FIG. 12 is a fragmental view, partly brokenraway and in section, showing a still further modified form of our invention.
Referring now to the drawings for a better understanding of our invention, we show a rotary ring i0 having a plurality of angularly spaced roller bearing members 11 which ride in an annular guideway I2 whereby the rotary ring 10 is supported for rotation. The annular guide member 12 is carried by a stationary member I3 which in turn is supported by a suitable frame indicated generally at 14. The roller bearing members 11 are supported on suitable shafts I6 carried by the rotatable member 10. As clearly shown in FIG. 4, an outwardly and downwardly extending ange member 17 is carried by the rotatable member 10 and is provided with a plurality of angularly spaced openings 13 therein for receiving the adjacent ends of the shaft I6. The other ends of the shafts 16 project through suitable openings 19 prow'ded i inthe annular member 10.
The rotatable member l0 is driven by a sprocket 21 which is secured to the flange member 17, as shown in FIG. 4. Passing around the sprocket 21 and a lower sprocket 22 is a sprocket chain 23. The lower sprocket 22 is secured to a shaft 24 which is operatively connected to a gear reducer 26. A clutch and brake unit 27 operatively connects the gear reducer 26 to a suitable prime mover, such as a motor 2S.
The article or articles to be wrapped, indicated generally at 29, are fed into the rotary ring lb by a suitable conveyor 31 which may have suitable power driven feed rollers 32. The article or articles 29 are removed from the rotary ring 10 by a second conveyor unit 33 which may have driven rollers 34. It will be noted that the conveyor units 3l aud 33 are spaced from each other whereby the tape may be wrapped around the article 29 in a manner to be described hereinafter without contacting the conveyor units.
Mounted on the rotary member I0 and projecting outwardly therefrom in a direction substantially parallel to the axial center line of the rotary member 16 is an elongated support member 36 which may be in the form of a shaft or the like. Mounted for rotation and axial sliding movement along the elongated member 36 is a tape supply roll 37 having an end 38 thereof extending inwardly of the rotary ring 10, as shown in FIG. 2. An annular core member 35 is inserted within the usual opening in the supply roll 37 whereby the roll is mounted for rotation on the shaft 36. Also a suitable spring 3S8l is mounted on the shaft between the core member 35 and a washer 35b whereby tension is applied to the supply roll to restrain rotation thereof. The outer end of the shaft 36 is threaded for receiving a retaining nut 35 whereby the tension applied by the spring 35a may be varied and the axial position of the supply roll 37 along the shaft 36 may be varied by positioning suitable spacer members 35d between the supply roll 37 and the adjacent surface of the rotary member I0.
Mounted on the stationary member 13 adjacent the rotary ring 10 is a bracket 39 which carries a reciprocable actuating member 41. As shown in FIGS. 1-4, the reciprocable member 4l comprises a pair of laterally spaced guide members 42 and 43 which are adapted for sliding movement through suitable openings 44 and 46, respectively, provided in the stationary bracket 39. The outer ends of the guide members 42 and 43 are rigidly secured to a housing 47 by suitable lock nuts 48, whereby the housing 47 moves with the guide members 42 and 43. Mounted on the stationary bracket 39 is a fluid pressure operated cylinder 49 which extends in a direction generally parallel to the guide members 42 and 43. Fluid under pressure, such as air, is supplied to opposite ends of the cylinder' 49 by suitable conduits 51 and 52. The cylinder 49 is provided with a piston rod 53 which is connected to the housing 47 by suitable lock nuts S4 whereby the housing 47 is reciprocated by the iluid pressure operated cylinder 49.
lvlounted at the lower ends of the guide members 42 and 43 is a bracket 56 which carries a pair of laterally spaced tape engaging members 57 and 58, which preferably are in the form of rollers. As clearly shown in FIGS. l and 4 of the drawings, the reciprocable member 41 extends inwardly of the rotary n'ng 10 at an inclination relative to the axis of rotation of ther rotatable ring. Accordingly, the tape engaging members 57 and 58 are in alignment with the inwardly extending end 38 of the tape when the reciprocable member 41 is in an inner position an -is out of alignment with the inwardly extending end 38 of the tape when the reciprocable member 41 is in an outer position. The reciprocable member 41 is shown in the inner position in FIGS. l and 2 ofthe drawings whereby the tape engaging members 57 and 5S are disposed adjacent the article 29 being wrapped.y
By providing axial movement of the roll of tape 37 i along the shaft 36, Ithe tape engagingmembers 57 and 5S can move inwardly to accommodate articles 29 of various sizes. That is, when a smaller article 29 is Wrapped with tape the members 57 and 5S would move further inwardly and away from the rotary ring 18 due to the fact `that the reciprocable member 41 extended at an inclination relative to the axial center line of the rotary ring. Accordingly, the roll of tape 37 would have to move outwardly along the shaft 36 `in order to be in alignment with the tape engaging members 57 and 5S.
Mounted for reciprocatory movement in suitable openings provided in the stationary bracket 39 are laterally spaced actuating rods 59, 61 and 62 having their outer ends operatively connected to yiluid pressure operated cylinders 63, 64 and 66, respectively. vThe actuating rods 59, 61 and 62 extend in a plane generally parallel to the guide members 42 and 43 whereby they also move inwardly of the rotatable ring at an inclination relative to the axis of rotation of the rotatable ring 1t). Fluid under pressure for actuating the cylinders 63, 64 and 66 is sup plied ina manner well understood in lthe art by suitable means, not shown.
Mounted at the inner ends of the actuating rods 59 and 62 are clampmerrrbers 67 and 68, respectively, which are in alignment with the tape engaging members 57 and 58, as clearly shown in FEGS. 2 and 3. That is, the clamp member 67 is adapted to move toward the tape engaging member 57 While the clamp member 68 isV adapted to move toward the tape engaging member S. Mounted at the lower end of the actuating rod 61 is a cutter 69 which is adapted to move into cutting relation with the tape between the tape engaging members 57 and 58.
Pivotally connected to the bracket 56 by a suitable pivot pin 71 are a pair of laterally projecting arms 72 and 73 having forwardly projecting wiper members 74 and 76, respectively, which may be in the form of rollers. As shown in FG. 3, the rohers 74 and 76 are adapted lto move into engagement with the ends of the tape applied to the article being wrapped. That is, the wipers press the Vfree ends or' the tape downwardly into sealing relation with the subjacent surface. Pivotally connected to lthe arms 72 and 73 intermediate their ends by suitable pins 77 and 78 are the ends of piston rods 79 `and 81 of fluid pressure operated cylinders 32 and S3, respectively. The cylinders 82 and 83 are pivotally supported'bysuitable pins 84 and `86 which project outwardly from support brackets 87 and SS, respectively. The brackets S7 and S8 are rigidly mounted adjacent the lower end of the reciprocable member 41 by a suitable means, such Yas by welding.V
VMounted non-rotatably on the shaft 24 is a sprocket S9 which is operatively connected to ars'procket 91 by a sprocket chain l92. The sprocket 911 is mounted non- Y rotatably on a shaft 93 having cams 94, 96, 97, 98,
99, 191, 102 `and 193 mounted thereon and adapted for rotation therewith. The shaft 93 is mounted for rotation in suitable bearings 104 and 1&6, Vas shown. The cam members 94 and 96 actuate switch elements 167 and 19S which are lin circuit'with solenoids 109 and 111, respectively. Current Vis supplied to the switch elements 197 and 10S and the solenoids 199 and 111 by suitable power lines 112 and 113. The solenoids 109 and 111 are operatively connected to a valve 1'14 which supplies uid under pressure to opposite ends of the fluid pressure operated cylinder 49. That is, when the solenoid 1tl-9 is energized, the valve 114 is moved to a position to introduce Huid into the cylinder 49 through conduit 51 whereby the reciprocable member 41 is lowered. On the other hand, when the solenoid 111 is energized,the valve 114 is moved to a position to introduce fluid into cylinder 49 through conduit 52 to thereby raise the reciprocable member 41.
The cam members 97 and 98 actuate switch elements V116 and 117 which are in circuit with the power line 112 and one side of electrical solenoids 118 and 119, respectively. The other sides of the solenoids 1118 Vand 119 are connected to the power line 113. The solenoids 118 and 119 are operatively connected to a control valve 121 whereby uid under pressure in introduced adjacent opposite ends of the fluid pressure operated cylinder 63. That is, when the solenoid 118 is energized the actuating rod 59 is lowered. On the other hand, when the solenoid 19 is energized, the rod 59 is raised.
The cam members 99 and 191 actuate switch elements 122 and 123 which are in circuit with the power` line 112 and one side of solenoids 124 and 126, respectively. The other sides of the solenoids 124 and 126 are connected to the power line 113. The solenoids 124 and 126 are operatively connected to a valve 127 whereby uid under pressure is introduced selectively at opposite ends of the lluid pressure operated cylinder 64. When the solenoid 124 is energ'med, the actuating rod 6'1 carrying the cutter 69 is lowered. On the other hand whenthe solenoid 126 is energized, iiuid under pressure is introduced into the cylinder 64 whereby the actuating rod 61 and the cutter 69l are raised.
The cam members 162 and 103 actuate switch elements 123 and 129 which are in circuit with the power l-ine 112 and one side of electrical solenoids 1311 and 132. The other sides of the solenoids 131 and 132 are connected to the power line 113. The solenoids 131 and 132 are operatively connected to a control valve 133 whereby fluid under pressure is introduced selectively at opposite ends of the fluid pressure operated cylinder 66. That is, when the solenoid 131 is energized, the lfluid under pressure is introduced into the cylinder 66 whereby the actuating rod 62 is lowered. On the other hand, when the solenoid 132 is energized the valve 133 is moved to a position to introduce fluid into the cylinder 66 whereby lthe actuating rod 62 is raised. Y
While we show each valve 114, 121, 127 and 133 as being actuated by a pair of solenoids, it will be apparent that each valve may be operated by a single solenoid vhaving a spring return, which is operated in a manner well understood in the art, thereby reducing the number of switches, cams and solenoids required.
The cam members 94 through 103 inclusive rotate with the shaft 93 wherebykthey actuate their associated switch elements in timedV relation to the rotation of the rotary ring 1t? in a manner well understood in Ithe art. The brake and clutch member 27 is provided with suitable control means Wherebyupon rotation of the rotary ring 10 a predeterminedangular distance, the drive connection betweenrthe lmotor 23 and the gear reducer 26 is interrupted. That is, the clutch is deenergized'after the rotary ring 1l) has rotated a predetermined angular distance. Also, immediately upon deenergizing the clutch, the brake is applied whereby rotation of the rotary ring 10 is stopped, thuscornpleting one cycle of operation. The
clutch and brake unit 27 may be energized and deenergized by a cam 80 mounted on the shaft 93 in position :to actuate a switch element 80a which in turn energizes and deenergizes a solenoid 85. The clutch and brake unit is operatively connected to the solenoid 85 whereby the drive connection between the motor 28 and the gear reducer is interrupted upon rotation of the rotary member a predetermined angular distance. No detail description of the gear reducer 26 and the clutch and brake unit 27 is given herein due to the fact that such apparatus is well known in the art.
Also mounted on the shaft 93 are cams 95 and 95a which actuate switch elements 100 and 100EL as shown in FIG. 5, the switch elements 100 and 100a are in circuit with solenoids 105 and 105a and the power line 112. The other sides of the solenoids 105 and 105a are connected to the power line 113. The solenoids 105 Iand 105al actuate valves 110 and 1103, respectively, which in turn operate the ' cylinders 82 and 83, respectively, whereby the wiper 76 moves into engagement with the end of the tape initially applied to the article 29 and the wiper 74 moves into engagement with the end of the tape last applied to the article. The cylinders 82 and 83 may be of the single action type whereby the wipers are returned to inoperative position immediately after operation of the cylinders 82 and 83.
From the foregoing description, the operation of our improved apparatus shown in FIGS. 1-5 will be readily understood. The article or bundle 29 to be wrapped with tape is conveyed into the rotary ring 10, as shown in FIG. l whereby the end 38 of the tape is in position to be wrapped around the article 29. In the starting position, the reciprocable member 41 is in the raised position. Also, the actuating rods 59 and 61 are in the raised position relative to the reciprocable member 41. The actuating rod 62 is in the lowered position relative to the reciprocable member 41 whereby the end 38 of the tape is clamped between the clamp member 68 and the subjacent tape engaging member 58, as shown in FIG. 3. Also, to add a new supply of tape to the apparatus, the elements of the reciprocable member 41 are in the position just described. With the end 38 of the tape clamped between the tape engaging member 58 and the clamp member 68, the cam member 94 actuates the switch element 107 whereby the solenoid 109 moves the valve 114 in a direction to lower the reciprocable member 41. The tape engaging member 58 having the end of the tape attached thereto thus moves into contact with the larticle 29 being wrapped. The clutch of the clutch and brake element 27 is then energized whereby the rotary ring 10 is rotated in a clockwise direction, as viewed in FIG. 2, thus wrapping the tape around the article 29. It will be apparent, however, that the rotary member 10 may rotate in a counter-clockwise direction by timing the sequence of operation of the associated apparatus for operation in that direction. After rotation of the rotary ring 10 has commenced, the cam member 103 actuates the switch element 129 whereby the solenoid 132 moves the valve 133 in a position to raise the `actuating rods 62 and the clamp 68 carried thereby to thus release the end of the tape clamped between the clamp member 68 and the tape engaging member 58. Cam member 96 then closes switch l108 whereby the solenoid 111 is energized to thus move the control valve 114 to a position to raise the reciprocable member 41, thereby removing the end of the tape from the tape engaging member 58. By :providing a tape engaging member in the form of a roller, the tape is easily removed from the member 58 as the reciprocable member 41 is raised due to the fact that the roller rotates as the member 41 is raised. Just prior to raising the reciprocable member 41, cam member 95 actuates switch 100 whereby solenoid 105 operates valve 110 to move wiper member 76 into engagement with the end of the tape which was initially applied to the article. The
free end of the tape is thus forced into firm engagement with the article 29.
The tape may be wrapped about the article any number of times. If two passes of the tape around the article 29 are desired, the cam member 96 is so constructed that it actuates the switch 108 to energize the solenoid 111 before the second revolution of the rotary ring 10 is commenced. That is, the reciprocable member 41 is in the raised position at this time whereby both tape engaging members 57 and 58 are out of alignment with the end 38 of the tape, thus permitting the tape to be wound on itself around the article 29. After the second revolution is commenced, the cam 94 actuates switch 107 to energize the solenoid 109 whereby the valve 114 introduces fluid into the cylinder 49 to lower the reciprocable member 41. The tape engaging members 57 and 58 thus move into engagement with the outer surface of the tape thus applied with both clamp members 67 and 68 and the cutter 69 in raised position. As the second revolution of the tape about the article 29 is completed, the tape passes over the tape engaging members 57 and 58 or between the tape engaging members and the superjacent clamp members 67 and 68.
Immediately after completion of the second revolution, cam members 97 .and 102 close switch elements 116 and 128 to energize solenoids 118 and 131, thereby lowering the clamp members 67 and 68 to thus clamp the tape between the clamp members and the subjacent tape engaging members. Cam member 99 then closes switch element 122 to energize solenoid 124 whereby the cutter element 69 is lowered to thereby cut the tape as it eX- tends between the tape engaging members 57 and 58 and their associated clamp members.
Immediately after the tape has been cut by the cutter element 69, the cam members 98 and 101 close switch elements 117 and 123 to energize solenoids 119 and 126 to thereby rm'se the clamp member 67 and the cutter element 6'9. The clamp member 68 remains in the lowered position whereby the end 38 of the tape is clamped between th-e clamp member 68 and the tape engaging member 58. The cam a then actuates switch 100a to energize solenoid a whereby valve 11105 yis actuated. Valve 10E operates cylinder 82 whereby wiper 74 moves into engagement with the end of the tape last applied to the article 29. The cam member 96 then closes the switch element 108 whereby the solenoid 111 is energized to raise the entire reciprocable member 41 whereby the apparatus is in position for another cycle of operation.
By applying tension on the tape supply means, the articles being wrapped may be forced into a compact bundle during the wrapping operation. That is, by restraining rotation of the roll of tape relative to the shaft -36 the tape draws the articles closer together.
In FIGS. 6 and 7 of the drawings, We show a modified form of our invention which is particularly adapted for applying a single revolution of Itape `about the article 29 being wrapped. The apparatus shown in FIGS. 6 and 7 is substantially identical to the apparatus shown in FIGS.
1 5, the principal dii'erence being that the bracket 39 v carrying the reciprocable member 41 is pivotally mounted on the stationary member 13 by a suitable pivot pin 134. Extending downwardly yfrom the bracket 39a is a depending member 136 having one end of a piston rod 137 pivotally connected thereto by a pivot pin i138. The piston rod 137 is carried by a uid pressure operated cylinder 139 which is pivotally connected to the stationary member 13 by -a pivot pin 141 and a suitable bracket 142. Fluid is supplied under pressure to opposite ends of the cylinder 139 by suitable conduits 143 and 144 whereby the bracket 39a is pivoted relative to the stationary ring 13, thereby positioning the cutter at selected angular positions. Accordingly, by moving the cutter element in the direction of rotation of the rotary ring after the tape has been initially applied to the bundle, the cutter element is in a position to cut the tape after the tape has overcutter whereby the tape overlaps the initial end ber 58a.
7 lapped the initial end applied to the bundle or article 29. That is, the cutter moves in a position to cut the tape at a ditlferent position from the original position of the applied to the article 29 prior to being cut. in FIG. 8 we show a further modified form of our invention Vin which a single actuating rod 62a is carried byA the reciprocable member 41a. The reciprocable member 412l extends inwardly of the rotary ring 10 at an inclination relative to the axial center line of the rotary ring in the same manner as the apparatus described hereinabove. Also, the reciprocable member 41a is provided with guide members 42,a and 439- and a lower bracket 56a which carries a single tape engaging member 58a. The actuating member 62E carries a clamp member 652L adjacent the inner end thereof in position to clamp the end 33 of the tape between the clamp 68a and the tape engaging mem- IMounted on the actuating member 62a is a iiuid pressure openated cylinder 146 which carries a depending piston rod 147 having a cutter element 148 mounted on the free end thereof. Fluid under pressure is introduced into opposite ends of the cylinder 146 by suitable conduits 149 and 151 whereby the cutter ele-V ment 148 is selectively raised and lowered into engagement with the tape.
The apparatus shown in FiG. 8 is operated in a manner similar to the apparatus described hereinabove. lnstead of having to lower the actuating rods 59 and 61 carrying the clamp mem-bers 67 and the cutter 69, the cutter 14S isfcarried by the actuating rod 62a. Accordingly, after the tape has made the desired number of rounds around the anticle 29 being wrapped, the tape is clamped between the clamp member 6321 andthe tape engaging member 53a. Fluid under pressure is then introduced through the conduits 149 whereby the cutter element 14S is moved into engagement with the tape to there-l by out the same adjacent the tape engaging member 53a. It will be noted that the cutter 148 is positioned quite close to the clamp member 68a whereby it is adapted to move into close proximity to the subjacent tape engaging member 51S7l as it is lowered. Accordingly, the tape is supported a sucient distance above the anticle being wrapped for the cut-ter to sever the tape.
The position of the reciprocable member 41 relative to the article 29 being wrapped may be varied by adjusting the elevation of the conveyors for the article or by adjusting :the elevation of the entire rotary assembly relative to the conveyors. Also, the length of stroke of the piston rod 53 may be varied whereby the reciprocable member d1 would move to selected elevations to accommodate various size articles.
In FiG. 9 of the drawings, we show the actuating member indicated generally at 41h as being mounted adjacent the lower portion of the rotatable member indicated at 19h whereby the tape engaging member 58br is adapted to move into engagement with the under surface of the article bein-g Wrapped indicated generally at 29". A tape supply roll 37b is mounted on the rotatable member b and is adapted for rotation therewith as described hereinabove with reference to the apparatus disclosed in FIGS.
1 8. The inner end 38h of the tape is adapted to be enga ged between the tape engaging member 58b and a clamp member 63' in the manner described hereinabove with Y hereinabove, the only difference being the position of the actuating member 41h relative `'to the article being wrapped.V That is, by causing the actuating member 41b to move upwardly of the rotatable member 10b whereby it engages the under surface of the article 29h to be wrapped, the point of contact between the article and the actuating member is always at the same point. Accordingly, with the apparatus shown in FIG. 9, it is not necessary t'o adjust the elevation of the conveyors relative Ito the rotatable member 1Gb, or Vvice versa, in order to accommodate articles of various sizes. That is to say, regardless of the size of the article being wrapped, the bottom ofthe article will always lie in the same horizontal plane in position to be engaged by the actuating member 41b as it moves upwardly thereagainst.
Referring now to FIGS. l-G and l1 of the drawings, we show a further modified form of our invention in which the rotatable member 16 is mounted for rotation on astationary member 13 having an annular guideway 12c therein. The rotatable member 19C is supported by rollers 11C. l
Mounted on the stationary member 13c Vis a support bracket 39C which pivotally supports an actuating Vmember 152 by a pivot pin 153.V Theactuating member 152 comprises a iiuid pressure operated cylinder 154 having uid connections 156 and 157 for introducing uid at opposite Vsides of a piston 153. A piston rod E59 is connected to the piston 158 whereby upon movement ofthe piston 158, the piston rod 159 is raised and lowered. Mounted adjacent the lower end of the piston rod 159-is a' generally L-shaped plate-like member 161. Projecting outwardly from the lowerrend of the plate-like member 16.1 are tape engaging members 57cand 58". Preferably, the tape engaging members are in the form of rollers mounted at the outer ends of suitable support members.
A bracket 162 is mounted on the plate-like member .1.6i in position to support the upper ends of fluid pressure operated cylinders 63C, 64C and 66C. Suitable pivot pins 163 connect the upper ends of the duid-pressure operated cylinders 636, 64? and 66 to the plate-like member, as shown. An actuating rod 59 is actuated by the cylinder 63c whileV actuating rods 61c and 62C are actuated by the fluid pressure operated cylinders 64 and 66C. The lower ends of the actuating rods 59, 61 and 62c are pivotally connected to outwardly projecting arms 164, 166 and 167, respectively, which in turn are pivotally supported by the plate-like member 161, as shown. Clamp members 67c and 63C are carried adjacent the free ends of the arms 164 and 167, respectively, in position to 'engage the endV ot the tape indicated at 38.
A cutter element 69C is mounted adjacent the free end of the arm H6 in position to engage the tape 33 while it is clamped between the clamps 67c and 68 and their associated tape engaging members 57c and 58, as clearly shown in FIG. 11.
The actuating member 152 is moved about its pivot pin 153 by a uid pressure operated cylinder 168 having a piston rod 169. A pivot pin 171 connects the end of the piston rod `169 to an upstanding bracket 172 carried by the luid pressure operated cylinder 154. VThe fluid pressure operated cylinder 16?v is provided with suitable supply conduits 173 and 174 whereby iluid may be introduced into and exhausted from opposite ends of the cylinder.
The operation of the apparatus shown in FIGS. l0 and l1 is similar to that of the apparatus described hereinabove, the principal dierence being that the actuating member 152 is rst pivoted inwardly'in position for the tape engaging members to be in alignment with the tape 38c prior to being moved radially toward the article 29C being wrapped. That is, theV actuating member 152 is pivoted into the tape line by actuating the fluid pressure operated cylinder 168 and is then moved radially toward the article being wrapped by the fluid pressure operated cylinder 154. The cylinders 63C, 64c and 66C actuate the rods I59, 61? and 62c in the same manner as the cylinders 63, 64 and 66 aotuatethe'rods 59,61 and 62. Instead of having the `actuating member 152 reciprocate at an i11- 9 cl-ination relative to the axis of rotation of the rotatable member 10C, the actuating member is moved axially of the opening through the rotatable member 10c and is then moved radially inwardly toward the article being wrapped.
In FIG. 12 of the drawings, we show a still further modified form of our invention in which the rotatable member indicated at 10d is mounted for rotation on suitable rollers 11d which in turn yare supported by an annular guideway 12d carried by a stationary member 13d. Mounted on the stationary member 13d isan outwardly projecting support and guide member 176 which supports a sleeve-like member 177 carried by an actuating member 178. That is, the sleeve-like member 177 slidably receives the elongated guide member 176 whereby the sleeve member is adapted for sliding movement along the guide member 176. A suitable fluid pressure operated cylinder 179 having a piston rod 181 moves the sleeve member 177 to selected positions along the guide member 176.
Secured to the sleeve member 177 is a iluid pressure operated cylinder 182 having a piston rod 183 which is adapted to support a plate-like member 161 adjacent the lower end thereof in the same manner as the piston rod 159 supports the plate-like member 161.
The operation of the apparatus shown in FIG. 12 is similar to that of the apparatus described hereinabove. The actuating member 178 is first moved axially by actuating the iluid pressure operated cylinder 179 to move the tape engaging members 57c and 58c into and out of the tape line in the manner described hereinabove. The plate-like member 161 is then moved radially relative to the article being wrapped by actuating the iluid pressure operating cylinder 182 in the manner described hereinabove.
lt will thus be seen that the apparatus shown in FIGS. 10, l1 and l2 is adapted for axial and radiall movement relative to the article being wrapped whereby the tape engaging members and the clamp members 67c and 68, together with the cutter element 69, all move in a generally radial path when actuated by their associated cylinders. By providing such radial movement, the tape engaging members, the clamp members and cutter all move vertically toward the article being wrapped whereby it is not necessary to provide for lmovement of the tape roll relative to the support member therefor. Also, it will be apparent that the apparatus shown in FIGS. 10, 11 and 12 may be mounted beneath the rotatable member 10 and 10d in the same manner as the actuating member is mounted beneath the rotatable member 10b in FIG. 9 of the drawings.
While we have shown apparatus for moving the entire plate-like member 161 toward and away from the tape 38", it will be apparent that suitable mechanism might be employed with the plate-like member for moving the tape engaging members 57 and 58 toward and away from the tape line. Also, it will be apparent that other apparatus might be employed for moving the plate-like member 161 toward and away from the tape.
From the foregoing, it will be seen that we have devised improved apparatus for wrapping tape around articles. By providing an actuating member which is adapted to move tape engaging members, clamp members and a cutter element into and out of alignment with the tape, the tape may be readily applied to the article and then cut after the desired number of rounds of tape have been applied to the article. Also, by providing means for holding the free end of the tape in position for another cycle of operation after the tape has'been cut, the next article is wrapped without having to introduce the free end of the tape. By applying tension on the tape supply means, the bundle or articles being wrapped may be forced into a compact bundle during the wrapping operation.
While we have shownronly one reciprocable member 41 as being mounted for movement inwardly of the rotary member 10, it will be apparent that several such recipl@ rocable members may be associated with the rotary member 10, whereby various sizes of tape may be employed on a single machine or various size articles may be wrapped without having to adjust the position ofthe conveyor relative to a single reciprocable member.
While we have shown our invention in several forms, it will be obvious to those skilled in the art that it is not so limited but is susceptible of various other changes and modifications without departing from the spirit thereof, and we desire, therefore, that only such limitations shall be placed thereupon as are specifically set forth in the appended claims.
