As shown in Fig. 1, the mechanism may be mounted on a base 50 that is provided with wheels l, so that it may be moved around, and jackscrews 52, so that it may be supported in any desired location. This base is one that is used in connection with a bottlel forming machine, Serial No. 688,470, file-d August 5, 1946, by this inventor, although it will be understood that the take-out or Ware moving mechanism may be used to advantage with other glass forming machines and the like.
The glass forming machine outlined consists of a rotating table that has mounted thereon a plurality of molds which go through certain stages of processing glass into ultimate glassware,
4 with the result of producing completed bottles at a particular point in the rotation.
This machine, in general, includes a drive mechanism, generally designated at 54, which drive mechanism operates a larger gear 55 rotatably supported upon the table 50. The machine, as set forth in the application previously mentioned, has a central column, indicated generally at 58, about which this gear 55 is caused to rotate. The gear 55 is connected with a ro tating table 57 that supports parison mold ele-- ments 58, in which parisons are formed during the rotation of the table. When the parisons are completed, they are transferred by transfer mechanisms, fragmentally indicated at 59, to finish mold sets, generally indicated at 60. The finish molds are caused to open, as indicated in Figs. 3 and 6, when they are brought to the threeoclock position of Fig. l. In this position, the completed glassware, here shown as a bottle, is resting upon a mold bottom plate, which in the present instance is indicated as a vacuum transfer head, describedin greater detail in the copending application mentioned.
The base 50 has a projection 64 thereon that constitutes the principal support for the take-out mechanism of this application. This projection receives a standard of more or less channel shape, asV shown at 65, which is held by suitable screws 55 to the projection 65 of the base 50. This column has a bearing 51 in its base, and, aligned with this bearing, it has a bushing 68 at its top. Between the bearing socket and the bushing, there is an intermediate bushing 69.
The big gear 55 meshes with a small gear i2, keyed to a shaft 'I3 that is supported in a bracket 'H attached to the base 50. f
This bracket is formed to provide a space for the shaft to project downwardly but above the upper surface of the base 50. On this portion, the shaft 73 has a sprocket wheel 16 about which a sprocket chain 71 is mounted. This sprocket chain, in turn, passes around a sprocket Wheel 78 journaled on Ya lower vdriving shaft Asection 19 that is supported in th`e"bea'ring 61 and which also passes through the bushing 69. A suitable sprocket chain'tightening device 80 is employed.
By the foregoing arrangement, the shaft 19 will be driven coordinately with the rotation of the glass forming machine table 51 and the various molds mounted thereon.
An upper shaft member 83 is attached to the driving shaft element 19 by a combination coupling and whip reducing device 84, which may consist of a pair of half-round collar elements bolted together around the ends of the two shaft members and frictionally bound to them. By this means, the shaft 83 is caused to rotate co` ordinately with the rotation of the forming machine table 5l when the lbolts are tight; but relative adjustment between them may be made.
The shaft element 83 extends upwardly through the center ofthe bushing 68 and is rotatively supported at its top against a bearing 85 (Fig. 4). This bearing, in turn, supports one end of an arm 8l that extends across and is, in turn, supported upon the center column of the forming machine, as appears in the application referred to.
The bushing 68 receives a depending threaded cylindrical skirt 88 (Fig. 31) of a stationary support 89. This threaded portion 88 is in the form of a skirt vso that it may be slipped down over the shaft 83 and passed through the bushing 68. It may be internally bushed to aid staacoaeas bilization of the shaft 83. It haseJ keyway 90, into which a key 9| fits to hold the support 80 non-rotatably in the standard 65. A
There are two collars S2 and e3 above and below the bushing 68, which collarsare threaded around theskirt portion 03 and may be turned to alter elevation of the support 60, and then tightened against the opposite ends of the bushing.
The support 80 has an upstanding central` hub 24 (Figs. 28, 3l) and an annular flange 05 out from the hub S4. The hub 54 has a recess 06 therein that may receive `a thrust bearing.
There is a rotatable support for a plurality of take-out devices in the form of a framework. This framework includes a .lower ring or table Sii and an upper ring or table Sil, these being joined and held in spaced relation by a central column itil. Thiscolumn is shown more clearly in Fig. 8. It has a lower flange I3! andan upper flange H32. Below the lower flange, there is a rabbet that is adapted to interengage with the groove 536 of the stationary support 89 and to rest upon a thrust bearing therein. A similar rabbet projects from the upper end of the .flange |52 for purposes to appear.
The column |00 has a passage |03 therethrough so that it may be fitted over theV shaft Preferably, the opening |53 is enlarged between its ends, so as to provide a limited bearing area adjacent the ends of the column |353.
The column has a long slot `Ilid that passes through the wall of the column Mil! and a flat boss projecting therearound. A key |85, formed with a backing plate B6, is shown in Fig. 9. The key passes through the slot IEM and the plate engages against the flat projection and may be attached thereonto by screws, as is shown. The shaft 83 has an elongated keyway therein which is engaged Iby the key H35, so that the column and the parts secured to it are caused to rotate with the shaft (note the dotted line outlines at the center of Fig. 6). The elongated keyway'permits vertical adjustment of the framework.
The lower plate 98 is attached below the lower flange |0| of the column Ii by screws H33. The upper plate $9 is similarly `a tached above the upper flange |02 by screws H30. A series of guide bars Hextend between the lower and upper plates 98 and 50 and are arranged in pairs around the peripheries thereof. These guide bars, as shownin Fig. 19 (Sheet 6) for example, have reduced ends that pass through the lower and upper `plates 98 and S9 and receive nuts H3 for attaching the parts together. As shown in Figs. 34 and 35 (Sheet 8) the'lower table 93 has openings H4 around its periphery to receive the rods H2, and the upper table S9 has' corresponding openings H5. These guide bars cooperate in making a rigid supporting structure out of this rotating framework.
Fig. 35 shows that the lower table 33 is tensided,` with bosses adjacent the openings l. Alternate spaces between the bosss are connected by upstanding web portions H 'l which are joined by radial web portions I i8 that extend `along the spokes into the hub of the member. The interveningspaces are provided with webs having upper flanges H9 that are nush with the tops of the bosses.
Each pair of guide rods H2 flanking a web Il' receives a pick-up supporting bracket |20, shown detached in Fig. 39 (Sheet 8). The upper table 99 is broken away at approximately-.the sevenoclock position in Fig. 6i, so as to show the support of this bracket |20 between adjacent guide .rods H2. As shown, there are live such brackets around the rotary framework.
Each bracket has two laterally extending wings |2| and |22 (Figs. 6, Sheet 5, and 39, Sheet 8) that `have openings |23 therein to engage over the pair of guide rods mentioned and to slide freely thereon. Suitable bushings may beused as desired within` the openings IES.
Each bracket |20 has a rearwardly extending projection having a'plate-like surface thereon, this projection being adapted to receive an actuating cylinder. A longitudinal groove |25 is `accurately disposed in this portion. is, on the bracket |20, a forwardly and upwardly extending projection |28 that receives the ware holding rnechanismof the take-out device. The bracket |20, as clearly `appears in Fig. 5 (Sheet 4), has a transverse depending wall |33 to which an actuating cam device is attached. As appears also in Fig.123 (Sheet 6), the depending Wall |30 is provided with an opening |3| therethrough that has an enlargement |32 therein to provide a shoulder. A cam roller shaft |33, having several different diameters has one diameter that fits within the opening |3| and a larger diameter that nts within the opening |32. It likewise has a projectingthreaded end to receive a securing nut |34, by means of which it is held to the Wall |30. It will be seen that this gives rigidity to the connection `between the bracket |20 `and the shaft |33. At its outer end, the shaft |33 is reduced to receive a carri roller |36. Beyond this portion, the shaft |33 has a reduced threaded end that receives a washer and a, nut |31. This arrangement provides for the free rotation of the roller |35 on the shaft without binding. A bore |38 may be provided, as shown in dotted lines in Fig. 23,for the introduction of, oil to the bearing of the earn roller, which is shown as having a bushing therein.
As heretofore noted, the rearward extension |25 on each bracket |20 is adapted to support a power cylinder. Each power cylinder |03 (Sheet 4) has a fiat bottom with a projecting tongue thereon that interts `closely with the groove |26 in the bracket. Thisaffords accurate axial disposition of thecylinder. The cylinder is held to the bracket by machine screws lill that engage in holes |42 Vin the` rearwardly extending projection |25.
The cylinder has a removable cylinder head n |43 closing its end.` It is adapted. to receive a piston |44 that is attached to a piston rod |45. rlhis piston rod passes through a packing gland |46, such as that shown in Fig. 5, attached to the end of the cylinder |43. The piston rod Miti vhas a yoke |41 integrally formed with the outer end thereof. The two ends of the yoke H31 fit into slots formed between two arms of links |48, shown in Fig. 18 (Sheet 4) Yin side elevation and appearing also in Fig. 6 (Sheet 5). Yoke pins |49 pass through the two arms of the links t |43 and the ends of the yoke |47, so that the two links are pivotallyheld onto the ends of the yoke. These yoke pins are removably held in place by cotter pins (not shown).
On each take-out or ware engaging device, thc other ends of the links |48 overlie two take-out arms |50 (Figs. 6, Sheet 5, 36, Sheet 8). These two arms |50 are supported upon the outer end |28 of the bracket |20. As shown in Fig. 35, each arm has an `opening |52 therethrough. `Each hole |52 receives a bushing collar |53, the' skirt of which enters a groove |54 cut around'a threaded opening |55 in the end |28 of thebracket.
There A tie link |55 extends between the ,ends of the take-out jaw carriers |50. A pair of screws I 51 pass through the ends of the tie link and into the holes |55, clamping the bushing collars'|53 securely in place against the end |29 of the bracket, but permitting proper pivotal movement of the two take-out jaw carriers.
The connection of the yoke links |98 to the take-out jaw carriers is accomplished by means of eccentric studs |52 that are shown in Figs. 5 and 6 and are shown separately in Figs. 37 and 38 (Sheet 8). vEach of these studs has a reduced threaded portion Ithat passes through one of the openings |99 in the two jaw carriers |59, and receives an attachment nut on the bottom, as shown in dotted lines in Fig. 5 These eccentric studs have intermediate portions |95 that are shown in Fig. 38 to be eccentric of the threaded portion |69. These portions |95 are sized to lit accurateh7 lin the holes' |89. studs have heads on them designed to receive Spanner wrenches. By this means, the studs may be passed through the jaw carriers and securely held thereon. At the same time, they pass through the links I 49, which are thereby held pivotally connected to the jaw. When the nuts are loosened, the studs may be turned, and this will alter the distance between the adjacent parts of the carriers and the centers of the yoke pins |49. By this means, the two jaw carriers |59 may be individually given a line adjustment, so that the two will be closed at the proper positions.
The upstanding portion I 28 of each bracket |20 receives xedly a pin |98 that ts accurately within complementary cut-outs |89 in the carrie'r arms |50, so as to limit their maximum inward movement in a closing direction and prevent their passing over center.
Each of the take-out jaw carriers has threadopenings |13 to which suitable plates VM may be removably attached, these plates constituting the take-out jaws. They are sized and shaped to have the proper complementary recesses to engage the top of the ware at the finish thereof, and lift the same, supporting it by the iinish. It will be observed that the jaw carriers themselves have large complementary recesses H2, so that they may accommodate the largest ware expected. Accommodation for'different sized inshes is thereby made by merely changing the jaws i'lli.
From the foregoing, it lwill be seen that the reciprocation of a piston |49 in the cylinder hifi to its outermost position, shown in Fig. 5 and at the seven-oclock position in Fig. 6, will close the two carriers |59 together by the action of the links. When the jaws are thus closed together, the links |48 are preferably aligned. When the piston is drawn inwardly toward the center of rotation of the rotating support, the yoke iii-9 wiil withdraw the yoke pins |99 and these will act through the links to open the carriers I 59 to the positions shown at the eleven-oclock position in Fig. 6.
The operation of the piston is accomplished by a valve mechanism. There is a valve for each of the cylinders, these valves being mounted above the top table 99 of the rotating framework and spaced around the periphery thereof alternately with the ware take-out devices. Each valve (Sheets 4 and 6) includes a valve housing |99 that is held by screws i9! tothe top of the table 99. As shown in Fig. 34 (Sheet 8), there are suitable threaded holes |82 to receivethe screws I 9 I. Between each pair oi adjacent holes |92, the table 99 has a hole |89.
The 'I As shown in Fig. 5, each valve housing |90 has a bore therethrough, in which the upper valve plug end of a plunger |98 operates. This upper end slides pistonwise within the housing. It has an axial bore |89 extending a limited distance down from the top, and which communicates with two radial ports |90 and |9|. The housing |80 has a cap |92 threaded thereon. This cap receives a compressed air line |93. kBy this means, compressed air acts downwardly on the .top of the plunger |88 and urges it to its lower position.
The housing |80 has outlet passages |94 and |95 extending therethrough and communicating with lines |99 and |97, respectively. It will be seen that, when the valve is in its upper position, shown in Fig. 5, the radial passage |99 establishes connection between the air line |93 and the pipe |96, whereas the other radial passage |9| is not connected to anything. The valve plunger |88 has an upper radial groove |99 and a lower radial groove |99. The housing has an upper exhaust passage 290 and a lower exhaust passage 20| These passages lead through valves 292 and 203, respectively, and thence to exhaust. It will be seen that, when the valve is in its upper position, the radial groove |99 is in registry with the passage |95 and connects the other line |91 to exhaust through the valve 293, while the line |95 is receiving pressure from the line |93. Under conditions to be described, the valve plunger |88 will be lowered to bring the radial passage |9| into registry with the casing passage |95. This will bring the peripheral groove |98 into registry with both the casing passage |95 and the exhaust passage .299. In this case, the conditions in the lines |99 and |97 will be reversed, air pressure being delivered from the line |93 to the line |97 and exhaust being established for the line |96 through the valve 202. Under these conditions, the piston will be reversed.
A comparison of Figs. 5 and 17 will show that the line |96 is connected into the back end of the cylinder |49, which is provided with a communieating passage 205 for that purpose. The line |91 communicates into the outer end of the piston through a passage 295.
Each valve plunger |99 extends downwardly through one of the openings |94 through the upper table 99, as shown in Figs. 19 and 20. Below the upper table 99, the valve plunger |88 is forked and is united to a rod 299 iby a pin connection 2 0 that may readily be removed, it being secured by cotter pins, as shown in Fig. 19. This rod projects downwardly to adjacent the lower table 98.
The lower end of each rod has rst a threaded section .2| below which it has a square section 2 I 2. The edge of the lower table is provided with rectangular notches 2| 3 that receive the squared section 2|2 and guide the same. Each squared section 2|2 likewise passes through a guide bracket 2|5, one of which is shown particularly in Figs. l0, 19 and 20.
These guide brackets 2|5 have bottom plates that nt against the top of the periphery of the lower table 98 adjacent the notches 2|3, and they have central depending key elements 2 6 that interit with slots 2|`| in the lower table 98. By this means, proper alignment of the brackets 2|5 is obtained. The brackets are held in proper position by screws 2 I4.
Each bracket 2|5 has an upstanding portion 2I8 rising from the base plate, which is generally in the form of an open-sided square, in section.
Thisl receives the squaredsection 2|2 of the rod. There is a removable outer plate` 229 attachedl over this squared sectionV 2|8 by'screws 22|. By this means, the rods may be'easily removed. The squared sections 2 I2 of the rods, intertting with squared sleeves 2I8 andthe notches 2|3, prevent the entire valve plunger assemblies from rotating.
Above the top of the bracket, the threaded portion 2|| of each rod 2||lisV provided with a pair of nuts 223 that are adjustable and' lock each other. These determine the` maximum downward travel of the rod by striking the top of the bracket 215.
Below the bracket, the bottom end of each rod 209 is provided with a-stud 225 that interiits with suitably shaped openings in the bottom of the rod and is held by a setscrew` 225. This stud forms a shaft upon which a cam roller 221 rotates. As will appear, therotation of the several cam rollers 221 on their cam elements causes the valves to be opened and closed ink proper timed relationship to the operation of the take-out elements.
From the foregoing, it may be seen that the framework carrying the valves and the take-out operating members rotates about the central `shaf t 83 in timedrelationship with the rotation of the, glassware formingrnachine. The take-out members areV provided with the cam rollers |36 which govern their elevation by causing them to slide up and down on theiry respective pairs of guide rods ||2. At the same time, the several valves are provided with their cam rollers 221 that may be actuated to cause the valves to be operated and hence the take-out arms tobe opened and closed, at proper points during the rotation. These two cam rollers are.` governed by cams that aresupported upon the vertically adjustable support 9| that is rotativelyfixed relative to the rotating framework.
As shown in-Fgs. 3 and 6, the ware is` takenv from an open mold, comprising mold sections 230, and is moved with a horizontal component to a conveyor belt 23|. Fig.` 2 shows that there must be vertical movementfduringthis horizontal translation. The ware must be picked up of of the bottom plate 2'32 of the mold and slightly elevated so that it will clear the bottom plate. Thereafter, it must be lowered because the conveyor 23| isllower than the mold 230. The vertical movement of the take-out devices permitted by the rods I2 is suihcient-to accommodate the foregoing, which is accomplished by a cam track operating with the `roller |36.
This cam track comprisesgenerally a` circular strip 235 havinglseveral elevations. In horizontalview, this track 235 appears asa substantially complete ring, having its endsA 236 and 231 adjacent the take-outpoint (Figs. 6; '7). These two ends, as shown particularly in Fig. '7, are connected by a short trackelement 240, which completes the ring.
The startingtrack element 2LH)` (Figs. 7, Sheet 28, 32,` Sheet') is supportedfrom theiixed support 89 by a bracket24l. This bracket is attached by screws 242 to the periphery of the support 89 at the take-out point. It has `alxedidepending pin 243 projecting from its bottom, which pin interts into an opening in the support 89, by means of which the support bracket 24| is accurately positioned. The track element 240 is removably held to the top of` the. bracket 24| by screws 244. The interfaces of these two parts are provided with aktongue and groove arrange- 10- ment 2-45, byV means Qfhwhich` the track is` accurately positionedon the bracket.`
The trackelement 240 has a cam depression 241 in its upper surface, whichj depression is below the level of the end 23BA of the track ring 235; and further belowthe end 231 of the track ring. Consequently, when the cam roller |36 rnovesto` the right in Fig; 7, which is`.counterclockwise` in the other views, itv will first risefroin the depression 241 and then move onto" the track ring 235 at the level of the end 236-.` After the roller has passedv entirely around the ring `to the end 231, it will be somewhat higher than it was on the end 236, but it will descend intothe groove 241. While it is in the groove 241', the take-out device is lowered to theposition shown in Fig., 2,V wherein the take-out jaws are properly7 lowered to` engage below the iinish ofthe ware that rests then upon the moving' mold` bottomplate 232. The initial movement of the camroller will lift the ware off of the bottom plate while it moves it `-counter clockwise with respect, to theaxis 83:
The end 238 ofthe camtrack 2351s shown in Fig. 30. i This end extends `horizontally until' it reaches a second supporting bracket 259| which is similar tothe bracket 24| and,` issimilarly attached to the support `89 andtothe cam track ring. Just beyond the bracket 25.9, the cam track ring has a descending portion 252; `T n the exampleV shown, this descending `portion continues until a point approximately 9,0 counterclockwise from the starting point. At thispoint, the track againhas a horizontal section 25,3. This section is supported `upon a bracket 254"to which it is attached by'screws 25.5' This` bracket 25ll`is held tothe support 89 by screws 25S.
The horizontal section`2534 continues for approximately 90 more and issupported at its other end upon a bracket 258 that may be the same as the bracket 254'. Just beyond" the bracket 258, the track rises-in a section 260 which occupies about 90i Midway of this rise, the track is supported upon a bracket 26| (Figs. 2,8l and 33), to which it isheld by screws. At approximately 270 from the-starting point, the'track reaches a final horizontal section 2,63. A'tthis point', it is supported upon a bracket 264; This horizontal section 231l is at a `somewhat higher elevation than the other end 236; Between the brackets 264,` and 24|,there'may be an additional bracket 265'. It will be understood that all of these brackets are attached to theperiphery of the support89.
From the foregoing, it will be seen that' in a single revolution of the framework each of the take-out devices is caused to move from its starting position shown in` Fig. 7, ina' complete'revolutioh, during which it first rises slightly to lift the ware out ofA the mold and olf of the bottom plate.V Thereafter, it descends` to dispose the ware at the `level of the conveyorESl. 'It remains at the lower level until approximately 180 after the startingv point, when it again rises toa level slightly higher than the level of" the end23`6lso that thetake-out jaws may pass acrosstlie top 'of the ware. lt finally descends againA into the' groove 241, at which point itis ready once more to receive another piece of ware.
Thevalve cam: roller t'loperatesso that the take-outV jaws` will close` over the linish of the ware at the startingposition shown in Fig. 6. They remain closed until the Vware is over the conveyor 23| when they again open; These operations are performed by cam elements `upon which the cam roller 221 acts. i'
As shown in Figs. 24 through 29 (Sheets 6v and '1) there is a composite valve actuating cam consisting of two elements 215 and 216. The element 215 has a base flange from which an upstanding cam track wall 211 rises. This arcuate wall projects beyond the base flange and has an` elongated slot 218 init. The projecting portion overli'es a recess 219 cut into the upstandingcam wally 280 of the element 216. A setscrew 23H passes through the slot 218 and is threaded into a hole 282 in the flange of the element 216, so that these two parts .may be held together. lit will be seen that jointly they provide a continuous arcuate cam wall, the length of which may be varied by adjusting their relative positions which is permitted by the engagement of the screw 29| in the slot 218.
The two elements 2 15 and 210 are attached to the periphery of the support 89 inwardly of the cam track 235. It will be'seen that the support 89 has a plurality of elongated arcuate slots 235, 286, 281, 288 and 289. The base plates of the two cam elements are provided with a series of threaded openings 290, 29|, 292 and 293, respectively.
The opening 290 receives a screw 295 (Fig. 20) that passes through a bushing 296 which, with the screw, pass through the slot 235. The screw is nally threaded into the opening 293. The bushing around this screw also receives another member which will be described. The other attaching means for the track elements are typified by the one shown in Fig. 29. A screw 291 passes through a bushing 298 that fits slidably within the slot 281, and is threaded into the hole 232r in the track element 216. By this means, the track is held securely to the support 83, but may be arcuately adjusted therealong.
This adjustment is accomplished by a rod 333 that has an eye on its end that ts under the bushing 296 and surrounds the same. This rod extends outwardly, as shown in Fig. 28 and Figs. 19-22, to engage threadedly through a hand adjusting knob 30|. This knob has a bearing portion 302 adjacent a flange 303. The portion 302 ts through a swivel 305 and is secured by a collar 306 held by a setscrew 301.
The swivel 305 has a shank 333 that has a reduced threaded portion 309 at its upper end. This shank 303 passes through an opening in a bracket 3|0 that extends from and is supported upon the support 89 by screws 3l I. A nut SI2, with a suitable washer, holds the swivel rotatably onto the bracket 3 I 0.
It will be seen that when the handle or knob 30| is turned, the screw 300 threaded into the knob will be drawn outwardly or forced inwardly. This causes displacement of the valve cam track. In order to adjust the cam track 215 alone, it is necessary to loosen the screw 28| first. Otherwise, both cam trackelements 215 and 216 will be simultaneously adjusted. l
From the foregoing, it may be seen that the valve cam roller 221 will engage the starting or most clockwise end of the cam track portion 211 at the time when the associated take-out device is over the ware with its roller engaged in the cam track notch 241. This will cause the piston to move outwardly, closing the take-out jaws on the ware. This cam roller 221 will remain up while the framework rotates approximately 130, when it will then descend olf of the other end 230 of the cam track. When this occurs, the jaws will again open, releasing the ware onto the conveyor 23|.
Airis supplied to the valve.forthe actuation of the piston from a lineY 32.5 (Eig. 4 )that^is con-r nected into the top of the arm-31. Thel-.outer-end of thisarm has a passage 323,therethrpugh. 'Ihe lower end of thisarm, at its outer end has a recess 321 therein that receives a rabbeton the upper end of a Vcombined stuiiing box and Vguide 328.
k This guide is secured to the armby. screws 329 that in the flange of the member328., 1
This guide has abore therethrough which has a first enlarged portion 330 thatAv receives the bearing 86. There is a lower reduced portion 33| that is sized to give support and bearing tothe upper end of the shaft 83., B y this arrangement, the outer end of the arm 81 is supported upon the shaft. The upper end ofv thevshaft is flanged and is engaged by a shaftl retainer formed of two half rings 332 and 333 that engage-under the flange and Vfit within the opening 330 inthe box member 328.
The stuffing box pass through the arm and into threadedopenings re receives packing s35- that 'is held in place by a packing fglandY 336 that is attached to the lower end ofthedbox by screws, as shown. This glandalso furnishes a guide means for the upper end of the shaft..VV
The upper end of the shaft has anopelning 340 that registers with=the opening 326 in the arm 31, communication being establishedthrough the center of the ,bearing 83.v At the bottom end of this bore 343, there is aradialpassage V34| that extends to the outside of the shaft.- At this point,
the shaft is surrounded by a,V distributor 342 that nts over the shaft 93, as shown in Fig. 4. -It isat-i taohed to the shaft by a setscrew-343. It provides an `air chamber 344 from which five pipes 345 extend, there being one pipe for each of the valves,
the pipes being connected to therilexible lines |93.
A brake means is providedto smooth out irregularities in rotation of the parts. This brake is shown particularly in Figs. 4, ll fand'l2 (Sheet 3) lit includes a drum formed of two complementary semi-cylindrical members 350 and 3'5 They are fitted together by a groove and rabbet 352, as shown in Figs. 11 and l2, and held by screws 353. This arrangement assures proper alignment of these parts. The cylindrical periphery of these two elements furnishes a groove 354 in which brake band and shoe means operate.
As shown in Fig. 12, there is a somewhat flexible band 355 that passes around the groove 354 and has fittings 356 riveted thereto to provide clamp end 351 that normallyare spaced slightly apart when the brake is in its operating condition. This band is provided with a bra-ke lining 358 that may be clamped against the drumg349 in a manner to apply friction to the drum,.so thatthe rotation ef the shaft maybe deterred. The' :operating means for this brake includes, apspringibolt 360, having a hole throughits headjand;.a threaded shank 36| that passes through openings'in the two ears 351. This shank is surrounded .by a compression coil spring 362 that is retained by a nut and. washer arrangement 363.- Adjustment of the nut changes the force of the springI tending to bind the brake band on the drum.
The head of the bolt 360 receives a screw 365. that passes up into a brakeanehor Ypost 366 having a threaded end 361 passing through the flange on the arm 31 and attached thereto by a nut 363. By this means, the band 355 and its lining 358 are held non-rotatablywhilethe drum rotates, and. the brake may4 be caused to apply. anyY desired friction to the rotation of theshaft..
When the glassware forming machine is rotat ing its molds about its central column, the center shaft S3 of the take-out mechanism will be rotated in time therewith through the medium of the sprocket arrangement shown in Fig. l. The timing is such that one take-out device is introduced to the starting point, which is the nineoclock position in all of the plan views in these drawings, every time a 1nold`23|l is brought to the same position by the forming machine. The forming machine illustrated here, which is described in detail in the applicants copending apn plication, has ten mold sets on it, and, for the type of ware illustrated, may be operated at six revolutions per minute, which presents a mold 233 at the starting point of the take-out every sec ond. For such speed of the glass machine, the take-out device must rotate twice as fast, or twelve revolutions per minute, in` order to bring a new take-out set to each new mold. The speed change afforded by the sprocket mechanism produces this proper relative rotation. It will be seen that, if the speed of the forming machine is changed, the speed of the take-out machine will change correspondingly. The speed ratios are determined solely by the number of mold arms on the forming machine relative to the number of take-out arms on the take-out machine.
Air is continuously supplied through the line 325 to the bore 33oin the top of the shaft 83 and to the distribution chamber 344. From this, it is constantly supplied through all of the outlet pipes 345 to all of the valve housings |32, where it applies pressure to the top of the plungers |23 and urges them downwardly as far as they are per mitted to go.
To explain the operation of the machine, it is suiiioient to explain a single cycle for one oi the take-out devices. -t the point of take-out, the ware, here shown as a small-mouthed bottle, is standing on the bottom plate 232 of a inish mold, the sections 23) of which are open. A particular take-out device, approaching its take-out position, will bein the upper positionon its respective guide rods H2 caused by the riding of its earn |3t on the highest end 231 of the cam ring 23% (Figs. '"I, 30). .litsvalve will be in the lower position, owing to the fact that the valve cam roller 221 does not engage the end of the track 211 until the take-out jaws are in position to engage the ware. The jaws will be open..
The end 231 of the cam ring 233 is suiiieiently high to permit the leading take-out jaw to be moved over the top of the ware standing on the bottom plate of the mold.
Thereupon, the cam roller i3d descends into the notch 263i' on the cam track joining member, causing the talee-out device to descend onl its guide rods I i2 into an elevation, as illustrated in Fig. 5,` wherein the jaws may properly engage under the nish of the ware. At this operation, the jaws are sufficiently far apart so that the leading jaw may pass across the top of the ware and both jaws descend on opposite sides of the ware without engaging it, despite the continuan tion of rotation of the rotatable framework.
At a point properly synchronized with the disposition of the open jaws around the ware, the valve cam roller 221 rides up onto the cam edge 211, elevating the valve to the position shown in Fig. 5, porting the compressed air to the line Hit` that is connected `to the back end of the cylinder |40, and connecting the forward end `of the cylinder to the exhaust through the line |01.. The speed with which this-takes place is controllable by adjustment of the two, valves 2ll2 and 203. The piston is thereby forced radially outwardly, carrying the yoke |46 with it and causing the two jaw holders to close together under the force transmitted throughthe links |48. These jaws thereby Yclose over the ware engaging it irnrrle-s diately below the finish, as shown in Fig. 5,. This operation must be completed ]oy the time the take-out mechanism begins tomove beyond a precise nine-oclock position in Fig. 6, so that the ware will be held at` the time lateral force is applied to it. It will be understood that the mold set isrotating with the take-out mechanism, but the moldrotation will tend towithdraw the ware away from the take-out mechanism.
-immediately after the ware is grasped by the take-,out device, the cam roller Hifi leaves the groove2fi1 and rides up to the level of the end 236 of the cam ring. This action lifts the taireoutdevice and causes it toliit the Ware Off of the bottom plate of thernold.
The ware is then conveyed at a fixed eleva-tion for a desired distance, after which the cam roller |35 begins to descend the angular portion 2%32 of the cam ring. ,This permits` the take-out device to slide downwardly` on itsr guide rods H2, carryingthe ware with it.` The valve does not normally change its position during this operation, so that the ware continues to be held.,
After rotation of roughly from the starting point, the cam roller |36 reaches the lower portion 253 of the cam ring 235. This is arranged to provide proper elevation for disposing the ware on the conveyor 23 I.
When the take-out device reaches this position .to discharge the ware to the conveyor 23|, the valve cam roller 221 leaves the end 280 of its cam track, whereupon the valve plug descends and connects the line |91 to compressed air and the line |96 to exhaust. This reverses the pressure conditions on the piston |44, causing it to move inwardly, opening the take-out jaws and releasing the ware. The conveyor 23| 1s operated at a speed so that it will withdraw the ware from the take-out deviceas that device moves in its arc, counterclookwise in Fig. 3.
Thereafter, the take-out device continues until approximately from its` starting point, whereupon its cam roller |36 ascends `the incline 260 of the cam ring 235. The valve is not changed durmg this operation. l At some convenient point,
such as 270o from the starting point, the earn' roller |36 attains the elevation of the end 23"! of the cam track, so that the take-out device is ele` vated again to a position to pass its leading jaw over an item of ware and repeat its cycle.
It may be observed that, with` this talreeout machine, one take-out device is transferring one bottle while the successive take-out device is engaging a subsequent bottle from a subsequent mold.
The position of the conveyor 23| controls the valve cam operation. Ordinarily, the cam ring 235 will accommodate any disposition of the conveyor 23|l around the take-out mechanism because the conveyor is not likely to be less than 90 away from the starting point of the take-out mechanism. However, it will be seen that this cam 235 may easily be changed by` being unscrewed from its supporting parts, so that one of different `characteristics may bcapplied to the mechanism.
o If the conveyor v23| is further around the takeout mechanism, so that it is substantially greater than the approximately 90 from the starting point that it occupies in the present illustration, the valve cam will require adjustment. This will require loosening the screw 28|, so that the cam element 21B may be advanced counterclockwise around the support 9|, thereby to change vthe point at which the jaws of the take-out'devices are opened. If the position of the conveyor 23| is beyond the maximum permissible adjustment of the cam element 215, a cam element somewhat longer may be substituted and supported by a screw passing through the slot 289.
As already noted, the point at which the valve initially moves to its upper position to close the jaws of the take-out device requires accurate adjustment, so that the timing will be proper. Such adjustment may conveniently be made by operation of the hand nut which draws or propels the screw and thereby displaces the rst section 215 of the valve operating cam. The screw 28| should be loosened prior to such adjustment in order to avoid changing the position at which the jaws subsequently reopen. However, slight displacement of the end of the cam is not usually critical, so that accurate timing of the lifting of fthe valve plugs may be made by moving the hand wheel 30| during operation of the machine.
The shape of the finish of the ware, and particularly its elevation, may require particular attention to the height of the take-out deviceras it approaches the starting position and the elevation to which it descends at the take-out point. These two factors are controlled by the connector Zeil between the two ends 235 and 231 of the cam ring 235. These connectors 240 are'readily removed and replaced by diierent connectors having grooves 241 of different depths and shapes. The key arrangement 245 insures proper alignment of the supplement that-is actually installed. The track ends 236 and 231 are sufficiently flexible so that slight changes in elevation at these po-ints do not require changes in the supports for theY entire cam ring. However, if such changes in the cam ring are necessary, they can be made without great difficulty because the removab-ility of the supports for the ring.
For ware of different height, suitable accom- Irno-dationv is possible with this mechanism. If the bottle is a taller bottle, that .projects a greater distance above the bottom plate 232 of the mold, this may ordinarily be accommodated by adjusting the principal support 89 vertically. This adjustment is made by loosening the collars `92 and `$3 and turning the upper collar on its threads so that it raises or lowers the support 83 and all of the rotating mechanism, as is required. Such rotation of the collars cannot turn the support because .the same is keyed into the upper bushing 68 of the standard. Then the proper elevation is attained, the collars are both tightened rmly against the bushing, so that the adjustment will be held. These collars are designed to receive wrenches. y Y
If there is a change in the level of the bottom plate 232 relative to the level of the conveyor 23 l, this may be taken care of by employing different take-out jaws. Reference `to Fig. 5 will show that these jaws have a Vertical dimension. This dimension may vary .with diiferent jaws and such variation will accommodate for differences in the levels of the bottom plates and the convey-or 23|. As already noted, these jaws may be changed so that they may engage ware of different shapes. The two valves 202 and 203 control the speed of operation of the piston UM, and hence the speed of the closing and opening movements ci the take-out jaws. This adjustment is worked in connection with the adjustment of the hand knob 30| to obtain proper timing, and it also is used to be sure that the jaws close at a speed that will not cause the ware to be struck with excessive force.
The jaws are prevented from closing over center by the pins |58. They may be individually adjusted by the eccentric screws |62, there being one such stud for each of the jaw elements.
The brake mechanism is designed to control the inertial tendency of the rotating parts to have jerky movement. The force applied by the brake is adjustable by adjusting the nut 363 that changes the force exerted by the spring 362.
It will be seen, from the description that has already been made, that the parts of the mechanism may be assembled and disassembled with facility. The several take-out devices are interchangeable, as are parts thereof. The cylinders all have corresponding keys that w-ill engage with any of the keyways, so that these parts may be used interchangeably. Other parts are similarly so designed. The guides 2|5 may be mentioned in this connection, because they have intertting keyways that facilitate their positioning and enable them to be changed. The valves likewise are interchangeable as units, as well as in their several parts. All of the parts that require lubrication are readily accessible.
The mechanism, as aforesaid, provides a high speed take-out machine that is very flexible in operation and adjustment, as Well as assembly and disassembly.
