Application July 24, 1952, Serial No. 300,608
33 Claims. (Cl. 22614) This invention relates to improvements in bottle case filling machines of the character adapted for placing filled beverage bottles in cases, cartons, etc.
As beverage bottles are filled and sealed by the capping machine, it is necessary that they be placed into cases or cartons for handling. While the bottles usually are discharged from the filling machine by a suitable conveyor, a more satisfactory machine is needed for inserting the bottles into the cases or cartons.
Wooden cases usually hold a total of twenty-four bottles. However, bottles often are placed in cardboard or paper cartons in lots of six or twelve. It is desired to fill the cartons or cases with the bottles as these are discharged -from the bottle filling and capping machine.
One object of the invention is to improve the construction of case filling machines wherein the bottles will be separated into proper relation with each other for introduction into the case or carton to which they are to be supplied, and which machine will operate with a minimum of power required, and is relatively simple for the operation required.
Still another object of the invention is to insure that the required number of bottles are received in the machine in proper position for introduction into the case or carton before these are ejected to maintain the proper operation and functioning of the machine.
Another object of the invention is to receive the bottles in proper position for discharge and to support them in properly spaced relation by the necks thereof whereby these bottles will move uniformly through the machine and will be discharged properly therefrom for filling the receptacles.
These and other objects of the invention may be accomplished in a machine for filling cases and cartons with bottles that is power operated and substantially automatic and which works for long periods with little attention at a high rate of speed. It has provision for assembling a desired group of bottles, preferably twentyfour, according to the size of cases now customarily employed, which are carried into position by the necks thereof and properly spaced for insertion into the case.
Bottles can be received from one or more conveyor lines which are supplied to a flexible conveyor forming a gathering unit enclosed by guard rails on which the bottles are fed to the receiving unit of the machine. The gathering unit has provision for separating the bottles into respective rows which are fed successively to the receiving unit. The bottles enter the overhead powered rod bottle carriers and are carried by the necks thereof in suspended relation to points directly over the loading unit. The bottle carriers separate the bottles properly spaced from each other and have provision for insuring that the proper and desired number of bottles are received therein before discharge. 4
When the desired number of bottles are suspended in the receiving unit, a loading unit moves up automatically into receiving relation with the bottles therein. The loading unit preferably is so formed as to enclose the proper "ice number of bottles to be introduced into the case or carton and its action is so timed with respect to the movement of the case or carton that the latter is moved into place beneath the loading unit automatically as the latter moves up into receiving relation with the bottles. When the empty case is in proper position, the loading unit is released to move down in the machine and deposits the charge of bottles in the empty case or carton. While this is being done, another charge of bottles moves into position above the loading unit and the latter may repeat its operation.
When the loading unit returns to its top position, the filled case is discharged from the machine and at the same time an empty "case is positioned ready to receive another charge of bottles. In this way the machine has provision for affording a double action system by releasing a charge of bottles into an empty case while at the same time moving a new charge of bottles into the receiving unit ready to direct the same into the loading unit when it is moved up to a position in proper relation therewith.
The loading unit is not powered but is operated by gravity provided by the filled bottles themselves. Weights are used attached thereto to inove the loading unit to its raised position and the filled bottles overbalance the weights to lower the loading unit and direct the bottles into the case or carton. The loading unit preferably is so constructed as to provide a minimum of breakage and to insure a proper direction of the bottles, both into the loading unit and therefrom into the case or carton, properly centered and spaced for direction into the latter.

-The invention is illustrated as applied to a case filling machine, but in some of the drawings portions of the .machine are omitted for clearness of illustration. To that extent the drawings are somewhat diagrammatic, although they will illustrate the structure of the machine fully and clearly.
In describing the operation of the machine, it will be understood that it is applicable not only for filling the usual wooden cases, but also for filling paper cartons of diffcrent sizes. In referring to the filling of cases, it will be understood that this has reference both to wooden cases and to paper cartons or carrying cases of the usual character.
The case filling machine comprising this invention is adapted to be used adjacent a bottle filling machine or machines and to receive the filled and capped bottles therefrom. The bottles ordinarily employed in connection with this invention are those customarily used for containing carbonated beverages. Such bottles ordinarily are provided with crown caps applied over a locking ring adjacent and spaced from a holding ring customarily formed on the neck of the bottle.
Fig. 1 shows the case filling machine with a row of bottles moving thereto along a chute from a bottle filling machine. However, it will be apparent that the machine may receive bottles from more than one filling machine, such as two machines, in which event two rows of bottles will be fed thereto.
. The case filling machine includes a supporting frame structure, generallydesignated by the numeral 2 in Fig. 3, mounted upon supporting legs 4 (Fig. 1) at the corners of the machine. The parts may be enclosed, if desired, by one or more side plates 6, secured to the frame 2 and extending about the sides of the machine. The opposite side plates 6 are provided with openings 8 therein adapted for the passage of cases C into and through the machine, these being received through one side, as shown at the left in Fig. 1 and discharged through the opposite side.
Gathering unit The bottle inlet end of the machine is provided with an endless conveyor 12, carried by drums 14 and 16, at the opposite ends thereof for the purpose of receiving the row or rows of bottles B from the chute or guideway 10.
This conveyor 12 is power driven, as shown in Figs. and 6,'by an endless chain or belt 13 extending over a drive wheel fixed to the shaft on which the drum 16 is mounted. The chain or belt 18 extends downwardly from the shaft of the drum 16 to a shaft 23, power driven by a chain or conveyor 22 extending thereto from a speed reducer drive unit 24. The speed reducer drive unit 24 is power driven in turn by a belt 26 extending over a shaft 28 connected with the speed reducer 24 and driven by a motor 30, as shown in Figs. 5 and 6.
The drum 14 is, in effect, an idler drum and provision may be made for adjusting the tension of the conveyor 12 by bodily movement of the drum 14. Accordingly, I have mounted the supporting shaft of the drum 14 in bearings 32 supported on pivoted arms 34, bodily adjustable lengthwise of the belt 18 by adjusting screws 36 threaded in suitable brackets in the frame 2, as shown in Fig. 6. Thus, by adjusting the screws 36, the arms 34 may be moved lengthwise of the frame to take up any slack in the conveyor 12 and thereby maintain the latter taut.
Any suitable conveyor may be used, as desired. However, I prefer to employ one formed of flexible chain links pivotally connected together in a mat of sufficient width to accommodate a plurality of rows of bottles. According to present practice, the bottles are packed customarily in wooden cases containing six rows of bottles with four in each row, a total of twenty-four bottles to the case. I have found that a chain-link conveyor of the type described, functions satisfactorily for collecting and spreading the bottles to the desired extent and for moving these forward in the machine to the loading position.
The gathering unit not only comprises the endless conveyor 12 but also means for dividing the bottles into multiple rows or distributing them transversely of the conveyor. Guard rails 38 are provided adjacent opposite sides of the conveyor 12, overlying the latter, and extending lengthwise thereof, as shown in Figs. 1 to 4. These guard rails 38 may be supported at their forward end portions by brackets 40 secured to a portion of the frame 2, and at their opposite ends. on brackets 42, also supported on the frame 2. The guard rails 38 have their inlet ends brought into juxtaposition, as shown at the rightin Fig. 3, to receive therebetween either a single row of bottles from one filling machine or two rows of bottles from two filling machines. According to this embodiment, only a single row of bottles B is supplied thereto, but these are spread laterally on the conveyor 12 into multiple rows, as described above.
The guideway or chute 44 is formed between the entrance ends of the guard rails 38 to receive the row or rows of bottles supplied thereto from the bottle filling machine or machines. This chute 44 is formed by a plate secured to the frame 2 of the machine and overlying the inlet end of the conveyor 12, between the guard rails 38, to direct the row or rows of bottles from the chute conveyor 1 onto the conveyor 12. a
Provision may be made, if desired, for spreading the bottles fed forward on the receiving conveyor 12. If two rows of bottles are fed from separate filling machines, usually the spreading device will not be required. While any suitable spreading means may be used, as desired, I have illustrated a conventional spreader, generally at 46 in Fig. 3, which is supported by a yoke 48 extending over the receiving unit and mounted on the frame 2. This will separate and spread the mass of bottles fed forward by the receiving conveyor 12 transversely substantially throughout the area enclosed by the guard rails 38.
A support plate 13 is secured at opposite sides to the frame 2 of the machine to support the upper run of the conveyor 12. This supporting plate is shown in Figs. 4 and 6 and extends substantially between the drums 14 and 16, as illustrated therein.
Extending transversely over the conveyor 12 is a spreader plate 47 mounted on supports 45 at opposite ends thereof on the frame 2. The supports 45 maybe in the form of spring arms to hold the plate 47 substantially on the top surface of the conveyor 12. As the bottles B are collected and moved forward by the conveyor 12, the bottles B are spread laterally by the plate 47 and the bottles are pushed over the plate in laterally spaced rows substantially across the width of the conveyor 12, and between spaced guides 49 sup ported on the main frame 2 of the machine. The guides 49 .divide the bottles into rows. The guides 49 are held in spaced relation by a support 51 extending transyersely of the frame .2 and mountedthereon and having the guides 49 secured to the said support.
Receiving unit The gathering conveyor =12 discharges the bottles -'B in multiple rows t to a receiving unit at the left ltahd side of the machine as viewed in Fig. 1. This unitco'mprises means adapted to receive'a'nd hold the bottles in multiple rows and properly spaced from each other for supply thereof to the loading unit, as hereinafter described.
The receiving unit comprises a supporting frame, generally indicated at 50 (see Figs. 6 and 7) which is mounted 'in turn on the main frame 2. Adjustable mountings are shown in Fig. 8 at 52 to 'vary the height of the frame 50 relative to the frame 2 to accommodate bottles of different capacities and for adjustment of the receiving unit relative to the loading unit where required for different sized bottles.
The frame 50 may be supplied with a cover 54, if
desired, comprising a sheet extending thereover to en close the receiving unit. This cover 54 is omitted in most of the drawings for clearness of illustration, and maybe omitted in practice, if desired.
As pointed out above, the receiving unit is adapted to receive and hold a plurality of rows of bottles properly spaced from each other by the guides 49, and includes "means carried by the frame 5% for accomplishing this result. Each holder (one for each row of bottles to be supplied to the case) is adapted to receive the necks of the bottles therebetween in a row, as will be apparent from Figs. 7 and 16to 19.
Each bottle holder for a row of bottles comprises a roll 56 and a bar 58 in spaced parallel relation, as illustrated in Figs. 17 and 18. These members 56 and 58 coact to form supporting members for the bottles, which members are spaced apart sufiiciently for freedom of passage therebetween of the necks of the bottles, normally received between those members.
The members are spaced apart insufficiently in their normal positions for the passage therebetween vertically of the holding ring and locking ring of each bottle. However, I have made provision for relative displacement of the members 56 and 58 to allow these bottle rings to pass freely out of the throat formed thereby when the bottles are to be discharged from the receiving unit into the loading unit, as will be described.
The rolls 56 are formed of steel or other suitable material and are smooth throughout their length. These are adapted to be rotated at relatively high speed-during operation of the machine in filling the case, and serve to facilitate the downward movement of the bottles along the throat as well as the separation of the bottles from each other. At the same time the smooth surface on each of the rolls 56 tends to separate'thebottles without danger of crowding in the throat and allows them to be properly spaced apart and to be retained therein until received by the loading unit.
Each roll 56 is journaled at one end on a support 60 (Fig. 18) suspended from the auxiliary frame 50, while the opposite end of the roll 56 is journaled in a bearing 62 mounted in a cross member 64 of the frame 50.
All of the rolls 56 of the receiving unit are interconnected by driving means, such as belts 66, for uniform rotation thereof by power at relatively high speed. These rolls 56 are driven by a power driving belt 68 (Fig. 7) which extends to a flexible shaft 70, mounted on the frame 2. The shaft 70 in turn is driven by a belt 72 from the shaft 28, described above.
The bar 58 is made in two sections, one of which is tiltablymounted for transverse turning movement about its longitudinal axis on a trunnion rod 76, while the other section 58' is stationary. The stationary section 58' is supported at 78 and 86 (Fig. 19) which supports are suspended from the frame 50, and are welded or otherwise secured to the section 58. The stationary section 58 carries a bracket 74 in which an end of the trimnionrod 76 is journaled. The opposite end of the trun- 6 nion rod 76 extends through a bearing :82 mounted on .t'hepross member 64 ofthe frame50.
The movable section of bar 58 is thus pivotally sup- ,ported for turning movement on .its longitudinal axis between the full -line and dottedline .positionsshown in Fig. '16. This is shown :as an angle bar and when in its dotted line .position, the lateral edge of the bar 58 will coactwith the roll 56 to form the throat therebetween thereby from the receiving unit.
Intermediate the length 'of the bar 58, adjacent the point overthe loading unit, the movablesection of each bar '58 is provided with a bottle retaining member or bracket 84 in position to enter between the last bottle of the row that is to be inserted in the case and the next following bottle entering the throat to hold back the latter during the-discharge of the row of bottles from the throat into the loading unit. This will preventthe following bottles from passing along the throat and dropping accidentally therefrom onto the loading unit or on top of the bottles therein.
\ Each bar 58 also carries a plurality of combined bottle spacers andholders, generally designated at 86, each of which is pivoted at 88 on the bar58, at the portion thereof over the loading unit. Each of these members 86 has a pointed or clearance end 90 directed toward the forward side of the receiving unit and a rearward 0; stop end 92 directed toward the rearward side there 0 The bottle spacers and holders 86 are of such length and so spaced with respect to each other along the length of each bar 58 as to be turned by the necks of the bottles into parallel relation with the bar 58, when the respective bottles are moved forward to their loading positions. -A bottle neck will engage the pointed end 90 of each holder -86 in its loading position, swinging the hol der-on the pivot 8 8 with itsrearward end 92 projecting out in the throat in the path of the succeeding bottle to stop the latter properly spaced from the next forward bottle, thereby holding these spaced from each other, as indicated in Fig. 17.
While -I have shown each bottle case C as adapted to receive twenty-four bottles, this will be :provided by six rows of four bottles each, which will be spaced apart by the holders 86 in the relation-shown in Fig. 18. Pro vision is made in the machine for receiving in each throat of the receiving unit some two or three additional bottles which will beheld back, however, by the stop member 84 during :the discharge of the bottles from the receiving unit. This stop member 84 normally is out of the path of the bottles moving into the throat, but as the bar 58 is turned on its axis to dischargeinto the loading unit, the member 84 willbe'turned down between the fourth bottle in each throat and the next following :bottle, which thereby will hold back the following bottles during the discharge. -A stop member 94 at the forward end of each throat will act to stop the first bottle rnoving-into the throat and additional bottles will be stopped by the members 86 in properly spaced relation therefrom and-from each other. 7 I
:No stopping action of the holders 86 will be applied until the first bottle in the throat reaches the stop 94 (-Figs. :17 and 18 In moving to-its forward-most position, each bottle will deflect the respective ends of each holder 86 and move past the bottles in the throat until the next forward bottle is in place beside the forward end 90 of a holder 86, which will then .prevent swinging of that holder and thereby will stop the next fol-lowing bottle in the throat.
The movable section of each ba'r 58 is provided'with 96' are connected together by a bar 95, which extends to a link 100 pivoted thereto. The link 1011 is pivotally connected with the upper end of an arm 102, supported by a stub shaft 104, shown in Figs. 20 and 21, which stub shaft 104 is journaled in bearings 106 supported by the sub-frame 50. The opposite endof the stub shaft 104 has fixed thereto one end of an arm 108, the opposite end of which is pivotally connected with a link 110 itltziched to a block 112 secured rigidly on a guide rod The guide rod 114- is slidably mounted for vertical movement in the frame 2 and in a guideway provided by a step bearing 116 on said frame. It is adapted for operation by the loading unit, as hereinafter described. Tension springs 118 and 12% connected with the arm. 198 properly tension the movement of the parts and provide for restoring the parts yieldably to their initial positions 'after operation for discharging the bottles into the loading unit.
Inasmuch as these bottle holding and release members are thus operated automatically by the raising of the loading unit to its receiving position, there is no danger of discharge of the bottles from the receiving unit until the loading unit is ready to receive the bottles therefrom.
Furthermore, the movement of the loading unit is caused by gravity and therefore gravity functions as the operating means for the release of the bottles from the receiving unit, whereby power is not required for this purpose.
The receiving unit is provided also with feeler means to ensure that a full complement of bottles will be contained therein before actuation of the receiving means 'to discharge the bottles therefrom. This feeler means is illustrated in Figs. 7 to 15.
Extending transversely over the throats of the receiving unit are shafts 122 spaced apart a distance substantially corresponding with the spacing of the bottles 13 in the throats. These shafts 122 are journaled at opposite ends in bearings formed in frame members 124 of the sub-frame 59. Each of the shafts 122 has provided rigid therewith, a saddle 126 overlying each throat of the receiving unit. The saddles 126 may be formed of wire or other suitable material and welded or otherwise rigidly fixed to the shafts.
Peelers 128 are journaled loosely on the shafts 122, and preferably, as shown, in the form of elongated 'bars. Each of the feelers 128 is pivoted at one end on the shaft 122 and extends laterally therefrom within a saddle 126, the free end of the feeler bar 128 normally being in position to be seated upon the cap of a bottle in its properly spaced relation in the throat of the receiving unit.
' These parts are so positioned relative to each other, as
shown in Fig. 11, that the feelers 12d normally rest in the saddles 126, in which event they exert a weight on each shaft 122 tending to rotate the latter in a clockwise direction, as viewed in Fig. 11. However, when a bottle is moved under the free end of the feeler 128, as shown "at the left in Fig. 11, the bottle lifts the feeler out of the saddle 126 and thereby releases the latter from the weight of the feeler.
' Each of the shafts 122 projects at one end through one of the frame members 124 and the projecting end thereof is provided with an arm 130 fixed thereon, as
the shaft 134 when permitted by the bail 132 acting .in their adjustment that as long as any of the feelers 128 are in the lowered positions in the saddles 126, the
weight of the feelers acting on each of the shafts 122,
will hold the correspondingarm or arms raised and ereby prevent swinging of the bail 132 and turning movement of the shaft 134.
Just as soon as all of the feelers 128 have been lifted out of the saddles 126, and all of the weight of the feelers taken off the shafts 122 and the arms 130, the counterweight 136 will rotate the shaft 134 as then permitted by the arms 130. This action will cause a swinging motion of a mercury switch 138 carried by the shaft 134, thereby closing the circuit to the solenoid 140 that controls the action of the loading unit, as illustrated in Fig. 31. Upon release of the loading unit by the actuation of the solenoid 140, the loading unit will be moved up to the receiving unit and thereby receive therein the bottles, as hereinafter described.
it has been pointed out above that the receiving unit will accommodate in the throats thereof additional bottles, more than the full complement of bottles to be introduced into the case. Additional feeler members may be provided if desired to act on the forwardmost of these additional bottles, as indicated at 142 in Fig. 11. The feeler members 142 will act to stabilize the bottles, as the latter are moved under the feeler members. These feeler members 142 are pivotally supported in saddles 144, supported bya transverse shaft 146 on which the feeler members 142 are pivoted.
Loading unit The loading unit is illustrated in detail in Figs. 22m 30. This leading unit comprises upper and lower sections 148 and 151), respectively, spaced apart vertically with an interposed grid plate 152 therebetween. Each of these sections including the grid plate is provided with a plurality of cells therein formed by intersecting partitions, welded or otherwise secured together, with the ells of the sections 14$ and in alignment with each other and adapted to be aligned with the cells of the 'grid plate 152. The number of cells in each of these parts corresponds with the number of bottles accommodated in the receiving unit and adapted to fit in each of the cases C. In the illustrated embodiment, there are six rows of cells, with four cells in each row, this being the relation of the bottles received by the throats of the receiving unit. a
The section 148 is provided with V-shaped notches 154 in each side of each cell at the upper end thereof, leaving upturned pointed corners on each cell as indicated at156 in Figs. 26 and 27. This has a tendency to direct the bottles into the cells without danger of tipping over in the opposite direction if misalignment should result. At the same time, there is less tendency of breakage of the bottles as a result of contacting of a bottle with a pointed edge rather than a uniform contact with a side of a cell, as I have discovered from actual experience therewith.
The cells of the lower section 150 are provided with downwardly projecting fingers 158 thereon, each of which converges inwardly acting as guides for the bottles as they drop from the loading unit into the case C. The fingers 158 are formed of fiat springs and may have longitudinally extending corrugated or ribbed portions 160 lengthwise thereof to stiffen the fingers and increase the resiliency thereof in acting on the bottles The loading unit is slidably mounted vertically between upright guide posts 162 and 164, rigidly fixed to the frame 2 at the top and bottom thereof as illustrated in Fig. 24. A guide bracket structure, generally indicated at 166, has portions thereof secured rigidly to the sections 148 and 151) of the loading unit, as will be apparent from Fig. 28, on opposite sides of the grid plate 152. The guide unit 166 carries a plurality of guide rollers 168, arranged in triangular relation, as shown in Fig. 29, to guide the 9 vertical sliding movement of the-loading unit-along the column 162.
The column 164 is .shown in Fig. 25 asan angle-bar. Accordingly guiderollers 170 are arranged to bear against opposite sides of one flange of the column 164 and thereby guide the loading unit in its vertical movement relative to this column. The rollers 170 are journaledina guide bracket 172 fixed at vertically spaced points to .the respective sections 148'and 1500f the loading unit.
The loading .unit is adapted to be moved upwardly by gravity, for which purpose I have provided flexible devices, such as chains 174 and 176, attached respectively to the guide brackets 166 and 172 at one end of each, and extending upwardly therefrom over guide members 178 and 180 carried by the frame 2 in elevated positions. The opposite ends of these flexible devices extend downward to counter-weights182 and 184, respectively, each of which is mounted in guides 186 mounted on the frame2. The counter-weights 182 and 184 serve to raise .the loading unit to the receiving unit to receive the bottles therefrom as soon as a full complement of bottles is contained within the receiving unit and a case C is in place beneath the receiving unit to receive the bottles therefrom. This action is controlled also by the solenoid 140 energized by an electric circuit controlled by the switch 138,
as described above.
The grid plate 152 is normally in the position shown in fulllines in Fig. 26 when the bottles'enter the load .ing .unit, in such relation that the transverse members of the cells of the grid plate are disposed intermediate the width of the cells of the receiving section 148, whereby to support the bottles in the latter until the loading unit .has moved downward to its lowermost position for discharge of the bottles into the case C. Slides 188 on each .opposite side of the grid plate 152 extend throughguides 190 on the section 148 to guide the back and forth movement of the grid plate relative thereto. Tension springs -.192 connected with theslides 188 normally tend to project the grid plate to the right, as viewed in Fig. 30, to the position shown.
The grid plate may be moved back for registry of the cells thereof with the cells in sections 148 and 150 by links 194 pivotally connected at one end of each to the grid plate 152 and at the opposite end to one arm of a bell-crank lever 196. The other arm of the bell-crank .1ever196 carries a bracket 198 adjustably mounted there- ,on by a pin and slot connection, generally designated at 200. A roller 282 is journaled on the bracket 188 in position to engage an abutment 204 secured to the frame or to the column 162 at one side of the loading unit, as .shown in Fig. 30.
The controls for the loading unit are shown in detail in Figs. 31 and 32.
A support structure generally designated 206 is secured to the column 162 in an elevated position beside the loading unit. The abutment 204 may be a part of this support structure or separately connected with the column. .It is shown on the opposite side of the column from the support structure. The structure 206 has arms 208 and 210 extending upwardly and downwardly respectively relative thereto and pivotally connected with the structure at 212 for lateral swinging movement out of the vertical plane of these members, as shown in Figs. 31 and 32.
Mounted on the arm 208 is an upwardly facing catch 214 pivoted to the arm at 216 and normally bearing against a stop 218 on the arm 208. A downwardly directed catch '220 is pivotally supported at 222 on the arm 210 normally bearing against a stop 224 on said arm 210. These catches 214 and 220 are in the form of bell cranks, one arm of each of which is positioned to engage and limit the movement of the guide bracket 166 as shown infFig. 32, while the opposite end of the bell-crank arm 214 projects laterally and is actuated by an interposed spring or springs 226 sleeved over a guide rod 228, slidjPQSltiOILtO engage an abutment 262 on the frame.

The spring orv springs 226. normally tend to holdthese respective members yieldably in their engaged positions against the .stops 218 and gizing of the .solenoid.140, when the receiving unit feeler mechanism has indicated a full complement of bottles, the solenoid will actuate the arm 236 and yoke 232 to move the arm 210 laterally,'releasing the catch 220 from the bracket 166, and thereby allowing the loading unitto move upward by gravity, acting on the counter-weights 182, 184. The bracket 166 will beengaged, aszit isthus moved toits upper dottedline position in Fig. "32,by the spring catch 214 and will be retained in such position until the .latter is released. A limit switch 240 in the circuit 241 of the solenoid controls'said circuit, with the switch 138 in series therewith. The switch 240 'will be'closed upon-engagement by the bracket 166 only when the loading unit is in its lower position.
The arm208 is provided with a pin 242, which isengaged by a yoke 244 on a shaft 246'carried by the supporting structure 206. The shaft 246 carries an arm 248 connected by a link 250 which extends downward to a cradle 253 below thecase receiving and guiding structure shown in Figs. 33 .to 36.
Thiscradle 253 is supported-by'one or more brackets 255 atone end thereof, which bracket 255 is pivoted intermediateitsends on-a shaft 258 that extends'from side to side of the frame 2 andiis supported thereby. The
lower ends .of the brackets 255 have a plurality of springs 260 connected therewith, the free ends of whichsprings are anchored to the frame 2.
At the forward end of the cradle 253 is an upright stop member 257 slidably mounted in a guide 259 on the frame 2. The stop member 257 carries a catch 261 in The stop member 257 is supported on a pivoted link 256 mounted -at=its opposite end on the frame and connected with the cradle 253 intermediate its ends. vA spring 263 normally urgesthe stop member 257 in one direction.
Extending outwardly from the opening 8 in a side of the casing-is guideway 264, also provided withrollers for freedom of movement of the cases C there-along by The .A feedzroll is shown at 266 intermediate the guideway 264 and the vcradle 253, which feed roll is continuously .power driven by a shaft 268 and gearing 270 from the m0tor.30, as .shown in Fig. 5.
Aroller support member is shown at 274 intermediate the guideway 264 and the feed roll 266 connected with an arm 252 which is mounted on the frame and pivotably connectedwith .the cradle253. The member 274 is adapted to 'be raised into the path of a case moving to the feed roll 266 to lift the case on the feed roll whenever an empty case is in position on the cradle 253.
"When a case C on the cradle 253 is filled, the weight thereof'willcause the forwardend of the cradle to lower against'the tension of the springs 260, rocking on the cross-shaft 258. A bracket 275 on the cradle 253 is connected with the link 250 moving the latter down to re- This same action also 257 ptravels down about three times as fast as the forward end of the cradle 253, due .to'the linkage connection therewith. The stop member 257 is latchedin this stop member 257 moves up approximately one inch, permitting the catch 261 to engage the catch stop 262.
When an empty case strikes the member 257 in this position, the catch 261 is released from the stop 262. This releases the member 257 allowing this member to move up further to the full position shown in Fig. 33.
Operation The bottles are received from the filling conveyor line or lines onto the power conveyor 12 of the case filling machine as shown at the right in Fig. 1. If the case filling machine is used in connection with a single bottle filling unit, the bottles are divided by the member 46 into separate portions laterally placed on the conveyor 12. On the other hand, if more than one line of bottles are received on the conveyor from separate filling machines, the division member 46 will not be required, but may be used where desired.
The bottles are then moved forward by the conveyor 12 to and over the plate 47 which lies flat over the conveyor 12, being spread out into a plurality of rows disposed lengthwise of the conveyor substantially throughout the lateral width thereof. These rows are shown, being the number customarily provided for cases of twenty-four bottles, although the number of rows may be varied according to the application of this invention. The bottles are separated in the respective rows by the spacers 49 which overlap the forward end of the conveyor as will be apparent from Figs. 1, 3 and 4. The bottles are carried forward by the conveyor 12 sufiiciently to cause their forward ends to be engaged by the receiving unit, directly into the respective bottle holders of the latter, formed by the members 56 and 58, shown in Figs. 16 to 19. Each row of bottles is directed into the throat of one of the bottle holders formed between the roll 56, which is operating at high speed, and the bar 58 which normally is turned to its full line position in Fig. 16.
Each bottle holder is outwardly inclined so that the bottles will have a tendency to be moved freely along the throat within the bottle holder where provision is made for proper separation of the bottles from each other, and holding them spaced apart. The first moved forward in each throat engages the stop member 94. It serves also to engage the forward edge of the spacer member 86, swinging the latter to its full line position in Fig. 17 and moving the heel of said member into stop engagement with the next succeeding bottle, keeping the latter properly spaced from the first bottle. The second bottle acts in like manner on the second stop member 86 and swinging it into holding relation with the third bottle. This action continues throughout the length of each bottle holder.
It is preferred that there be four bottles in each throat, although five bottles may be accommodated therein as indicated in Fig. 18, but only four will be discharged. The stop member 84 will enter the throat between the fourth and fifth bottles, holding back the latter during the discharge of four bottles therefrom.
Each of the bottles will be acted on by engagement of one of the feelers 128 therewith, lifting the latter out of its saddle 126 and out of pressure engagement with its respective cross shaft 122. The arms 130 on all of the cross shafts 122 are engaged by the bail 132 connected with the shaft 134 carrying a counter-weight 136 as shown in Figs. to 15. The relation of these parts is such that the shaft 134 does not rotate until all of the feelers 128 have been lifted from the saddles 126 away from pressure engagement with the cross shafts 122, by a full complement of bottles in the receiving unit. As soon as this happens, the weight 136 will turn the shaft 134 and the switch 138 mounted thereon to close the electric circuit 241 to the solenoid 14% The circuit 241 also includes a 12 limit switch 240 which is closed when the case holder is in its lower position.
The energizing of the solenoid 140 actuates the leverage 232-238 (Figs. 31 and 32) to disengage the catch 220 from the bracket 166. The loading unit, being empty at the time, will be moved upward in the machine by the action of the counter-weights 182 and 184 that are heavier than the empty loading unit, but lighter than the loading unit when filled. The loading unit thus telescopes over the suspended bottles hanging down from the receiving unit as illustrated in Fig. 8, with a bottle slipped into each cell of the top section 143 of the loading unit, where the bottles are supported by the grid plate 152 which normally is in the position shown in Fig. 26. This upward movement of the loading unit to its top position causes the bracket 166 to strike the pin 114 (Figs. 20 and 21), thus moving the latter upward and actuating the linkage 112 to shift the position of the movable sections of the bars 58 from the dotted line to the full line position shown in Fig. 16. The throat of each bottle holder normally is sutficient to receive the necks of the bottles therein and to hold the bottles by the guide rings on the throats. However, upon swinging movement of the movable sections of the bars 58, sufficient clearance is provided to allow the bottles to slip out of the throats and thus to discharge into the loading unit.
The bottles are thus retained in the loading unit in elevated position until an empty case is fed into the machine by the case feeding roller 266 onto the cradle 253. When an empty case strikes the stop member 257, the latter is released from the catch stop 262, permitting the case holder cradle 253 to swing upward, which is accomplished by the springs 26!) connected therewith. This upward movement of approximately one inch causes an upward sliding movement of the plunger rod 250 which acts to move the arm 208 on its pivot 212 and thereby disengage the catch 214 from the bracket 166 so as to release the loading unit filled with bottles for downward travel to its lowered position into the case, for unloading the charge of bottles therein.
When the loading unit reaches its lowered position, the roller 202 (Figs. 26, 30) carried thereby, engages the abutment 204, shifting the grid plate 152 from the position shown in Fig. 26 to a position aligning the cells in the grid plate with the cells in the loading unit. This releases the bottles in the loading unit for discharge by gravity into the case C which is in position beneath the loading unit in its lowered position.
The full case is held in this position until sufiicieut bottles for a charge are introduced into the receiving unit. As soon as the receiving unit is filled with a complement of bottles, the solenoid is energized by the closing of the circuit 241, releasing the loading unit for upward movement as described above.
As soon as the flexible guide fingers 158 on the loading unit clear the tops of the bottles in the loaded case, the cradle 2S3 drops down (Fig. 36), causing the stop memher 257 to be withdrawn out of the path of the now downwardly inclined cradle 253, thereby allowing the filled case to roll out of the machine by gravity onto a discharge conveyor. At the same time, this movement of the cradle causes the member 274 to be withdrawn from underneath the empty case allowing the latter to be lowered onto the feed roll 266 which causes it to move into proper position in the machine to receive the next load of bottles. The slight elevation of the next following case until needed saves the feed roll 266 from unnecessary Wear when no pressure is required.
While the machine is power operated, very little power is required inasmuch as the principal operations are performed by gravity, utilizing the weight of the bottles and the counterweights, to cause the vertical reciprocating movement and transfer of the loading unit andbottles from the receiving unit into the case as well as to cause the movement of the empty and full cases into and out of the machine. No clutch or variable speed devices are necessary as the presence of the bottles and cases alone control. the speed of themachine. The loading unit will not move up or down until bottles and case are present, thereby insuring a proper filling of the case with the bottles and preventing improper operation.
The entire machine is comparatively simple in structure and operation. The loading unit is mounted on roller bearings for quick and easy operation without undue noise or complexity of operation. It requires a minimum of floor space and little attention, considering the function performed thereby.
While the invention has been illustrated and described in one embodiment, it is recognized that variation and changes may be made therein without departing from the invention as set forth in the claims.
