- Each of the cartons 4 has a pair of side flaps 25 and a tuck flap 26 at each end thereon. At the end to be loaded, the flap 26 is depressed beneath a part of the article bucket 2, and at the other end the flap 26 is depressed beneath a rail 27. Thus, both of the tuck flaps 26 of the carton 4 are depressed and held clear during the loading operation wherein the articles are transferred from the buckets 2 to the cartons 4. After the articles have been transferred from the buckets 2 to the cartons 4, the side flaps 25 are folded inwardly and the tuck flaps 26 of, each carton are folded upwardly to be inserted into the carton, as illustrated in Fig. 4.
- the operation ofremoving and expanding the cartons 4 from the magazine 5 is initiated as the first trans member 6 is pivoted upwardly such that the suction cups 7 engage the bottom carton of the stack, Fig. 6, and at such time, a vacuum is applied to the suction cups via a flexible hose 28 and a tubular duct 29 passing through the transfer member 6. to :the suction cups 7.

9 Claims. (Cl. 93-53) This invention relates to article packaging machinery for packaging articles in cartons made of cardboard, or the like. More particularly the invention relates to apparatus for expanding the cartons and placing them in successive buckets or pockets of a moving conveyer.
Each carton for packaging articles comprises a front panel, a rear panel, a pair of side panels, and two sets of end closure flaps, one set of flaps being at each end of the carton, whereby a rectilinear enclosure is provided for the packaged articles. The cartons are in collapsed or folded flat position and stacked one upon the other, and a packaging machine is usually equipped with carton expanding apparatus which includes a magazine for holding the stacked cartons. The lowermost carton at the bottom of the stack is expanded by engagement with a member having suction cups, the carton being pulled downwardly by the member from the bottom of the magazine. Stationary guides between which the cartonmust pass, converge andimpinge upon the opposite edges of the collapsed flattened carton and gradually forces the carton to expand. To prevent the carton from doubling or folding longitudinally rather than expanding, a long thin member or finger is positioned to engage a long tuck flap at one end of the carton and to thence slide'into the carton. The finger exerts a restraining force upwardly against the upper panel of the carton while the lower panel is being drawn downwardly by the suction cups, and thus the upper and lower panels are caused to separate. Because of the desirability of inserting the finger into the carton at the beginning of the expanding operation, the cartons are stacked in the magazine with the flap side in up position i.e., each carton being placed in the magazine such that the tuck flaps at one end extend from the upper panel thereof.
Heretofore, cartons were expanded from a flat position in the magazine and were then moved laterally and placed in a conveyer bucket with the tuck flap extending from the top panel of, the expanded carton as it was positioned in the magazine. After the carton had been filled with articles, the flap would be folded downwardly over the end and thence tucked in at the bottom of the carton. This mode of packaging has proved satisfactorily, for packaging many articles, particularly those which have resilient or rounded edges such that no substantial restraint is offered to the tuck flap when it is tucked or inserted into the carton in a final closure operation. However, in packaging certain articles which are hard and have sharp edges, it has been found that such tucking operation is not accomplished smoothly since the tuck flap is prone to engage and be held by the sharp edges of the articles within the carton, the tuck flap in such cases being likely to buckle and become damaged with the result that the carton may not properly be closed.
This invention consists generally in a new and improved carton expanding apparatus wherein the cartons are passed downwardly and rotated substantially ninety degrees from the horizontal, and thence inserted into a conveyer bucket which is moving upwardly and around an end sprocket or other conveyer end support means. The bucket then moves with the conveyer around the end sprocket support and assumes a horizontal position;
ice
the carton is thereupon rotated an additional ninety degrees while in the bucket and its ultimate position on the conveyer is inverted from its position in the magazine.
It is an object of this invention to provide new and improved carton expanding and inserting apparatus, wherein the cartons are removed from a horizontal position in the magazine and are placed on a conveyer in a horizontal position inverted from the positioning in the magazine; thereby the cartons may be positioned flap side up in the magazine to facilitate expansion by insertion of the finger, and may be positioned fiap side' down in the conveyer to facilitate closure of the fiaps.
A further object is to provide an improved apparatus for transferring successive cartons from a magazine to buckets of a conveyer; the cartons being removed from the magazine by a first pivotal member having suction cups for engagement with a panel of the carton; the carton being passed, or relayed, by further pivotal members, from the first pivotal member to the conveyer bucket which moves upwardly by the conveyer around an end sprocket support of the conveyer.
A more complete understanding of the present invention, its mode of operation and its advantages, may be gathered from further reading of this specification, to-
gether with an inspection of the accompanying drawings.

2 of the conveyernl into. the cardboard cartons 4 on the conveyer 3. The cartons 4 are initially stacked in a magazine 5, Figs. 1, 2, 5, 6, 7 and 8, and will be removed therefrom by a first-transfer member 6 having a pair-of suction cups 7 thereon. Thesuctionfcups. 7 constitutera means:for gripping the bottom carton stacked inthemagazine 5.' The first transfer member6 is mounted to pivot about a point 8 and thereby to transport a carton 4 in, an arc downwardly. A second transfer member 9 will receive the carton/4 from the first transfer member 6 and will pivot about an axis 11? thereby transporting the carton 4 downwardly along a second arc. A third transfer member 11 mounted to pivot about .a
fer member 9 and will move the carton into a bucket .or pocket 13 on the conveyer 3. The conveyer 3 consists of a chain 14 which is supported by a sprocket 15 on a shaft 16, Fig. 5. The sprocket 15 rotates in a clockwise direction, as illustrated in Figs. 1 andS, and therefore the buckets 13 move from the left, upwardly around the sprocket 15, and thence to the right over the upper reach of the chain 14, Fig. 5.- A stationary arcuate band 17, Fig. 5, extends over the buckets at a portion of the conveyer 3 tosecure the cartons 4 therein. Subsequently to the arcuate band 17, the cartons 4 are held'within the buckets 13 by a rail 18 resiliently urged against the cartons 4 by a plurality of springs 19 and supported by a rigid bracket 20.
The movementof cartons 4 from the magazine to the conveyer 3 may be best understood with reference to Fig. 5. Each carton 4 is removed from the bottom of the stack of cartons in the magazine and transported downwardly through an arc illustrated by an arrow 6' by the first transfer member 6, shown in Figs. 1, 5, 6 and 7. The carton. 4 is thence moved through a second are 9' by the second transfer member 9. The carton 4 then moves through a third arc indicated by the arrow 11' by the third transfer member 11. Movement of the carton 4 along the conveyer 3 is indicated by the arrows 3, Fig. 5. It, will be noted by progressively following the movements of the cartons'4 in Fig. 5 that each carton is rotated from a horizontal position in the magazine 5 to a substantially vertical position whereupon the third transfer member 11 inserts the carton in the conveyer 3, and thence the carton continues to be rotated until it assumes an inverted position on the conveyer 3.
The cartons on the conveyer 3 move to the right and in spaced relation to the buckets 2 on the conveyer 1, as illustrated in Fig. 9. A pusher member 21-engages and moves the successive cartons 4 somewhat transversely of the conveyer 3 to place the carton 4 closely adjacent to the article containing buckets 2 to permit the articles to be loaded into the cartons 4 from the buckets 2 as both conveyers l and 3 move synchronously. Fig. 11 illustrates the relative positioning of the article carrying buckets 2 and the carton 4 positioned to receive articles therefrom. The article carrying bucket 2 rests upon and slides along a pair of rails 22 and is moved by a chain 23, Fig. 11. The buckets 13 of the conveyer 3 likewise rest upon and slide along a pair of rails 24 and are similarly moved by the chain 14. Each of the cartons 4 has a pair of side flaps 25 and a tuck flap 26 at each end thereon. At the end to be loaded, the flap 26 is depressed beneath a part of the article bucket 2, and at the other end the flap 26 is depressed beneath a rail 27. Thus, both of the tuck flaps 26 of the carton 4 are depressed and held clear during the loading operation wherein the articles are transferred from the buckets 2 to the cartons 4. After the articles have been transferred from the buckets 2 to the cartons 4, the side flaps 25 are folded inwardly and the tuck flaps 26 of, each carton are folded upwardly to be inserted into the carton, as illustrated in Fig. 4.
The operation ofremoving and expanding the cartons 4 from the magazine 5 is initiated as the first trans member 6 is pivoted upwardly such that the suction cups 7 engage the bottom carton of the stack, Fig. 6, and at such time, a vacuum is applied to the suction cups via a flexible hose 28 and a tubular duct 29 passing through the transfer member 6. to :the suction cups 7. With vacuum applied, the suction. cups 7 grip the lower lying panel 30 of the;.carton 4, as indicated by dashed circles 7, Fig. 3. Simultaneously, a thin member or finger 31 engages the tuck flap 26 extending from the upper panel of the carton 4 and moves inwardly such that the finger is inserted into the carton as the expanding operation is commenced. The. transfer arm 6 and suction cups 7 pull the bottom panel 30 downwardly, while the finger 31 exerts a restraining force tending to hold the upper panel 32 upwardly thereby separating the upper panel from the lower panel. The finger 31 is mounted to be resilient such that it is capable of moving downwardly with the carton 4 while offering an upwardv force thereagainst.- After thecarton has descended a predetermined distance from the stack'of cartons 4 and has begun to expand or open, the finger 31 is withdrawn permitting the carton 4 to descend further without interference therewith. As the carton 4 is pulled downwardly from the-magazine 5, an inclined guide rail 33 fixed in a stationary position cooperates with a 'pair of upstanding'lugs 34, Fig. 1, whereby the extreme edges or corners of the carton 4 are impinged and forced to assume a lesser dimension thereby causing expansion of the carton 4.
The second transfer member 9 pivots to a position for receiving the carton 4 from the first transfer memben as shown in Fig. 7. The second transfer member 9 includes a pair ofspaced apart head elements 36 between which the first transfer member 6,'with the lugs 34 and suction cups 7, may descend. Fig. 7 shows the positioning of the parts at the time of transfer when-thesecond transfer.
member 9 receives the carton 4 from the first transfer member 6. The firsttransfer member 6 with. the suction cups 7 thereon pivots between spaced apart jaws 36 of the second transfer member 9, and the'carton 4will be secured near each end. by anupstanding guide part 37 and a second upstanding guide part 38 having a protuberance 39 spaced to hook over one corner edge of the carton The carton 4 is thereby held between the upward extending stud parts 37 and 38 of the spaced apart jaws 36. The transfer arm- 9 is pi-votally mounted at a point 10 and has a rearward extension 41) which is pivotally connected to a link 41 and thus is drivirigly coupled to a rotatable crank 42. As the crank 42 rotates on a shaft 43,.the connecting rod or link 41 causes the transfer arm 9 to reciprocate or rock. about the pivot point 10, Figs. 1, 6, 7 and.8.
' The third transfer member 11 is. mounted to. pivot about the point. 12 and has fixed thereto a drive extension arm 44 containing a slideway 45. Another crank 46 rotatable on a shaft-47 includes a crank pin 48 slidably positionedin theslideway. 45'such thatrotation of the crank. 46 will cause. a pivotal or rocking motionof the second transfer arm 11 about the point. 12.. The third transfer .arm 11 also contains a pair of spacedapart jaws 49. The jaws 49 are spaced apart at a distance greater than the spacement betweenthe jaws. 36 such that the jaws 36 of the transfer arm 9-may move between the jaws 49 ofv the transfer. arm- 11, Fig. 12. Fig. 8. illustrates the positioning of the transfer parts atthe moment when a carton 4. is being received in the jaws- 49 of the third transfer arm 11 from the jaws 36 of the second transfer arm ,9. It will. be appreciated that the jaws 49 consist of a straight extended part 50 of the arm 11 and a transverselycxtending jaw part 51 having an upwardly extending protuberance 52 forming a hook to secure the corner edge of the carton-4. As shown. in Fig. 8, the guide part 38 moves downwardly below the positionof the jaw part 51 and, therefore, the carton 4 is impinged betweenthe guide part 37 of the-second transfer arm 9 and the jaw part 51 of the third transfer arm 11 and thereby the carton is further expanded at the time when the carton is received by the transfer arm 11.
The transfer arm 9 with the guide part 37 thereon forms a guide surface for the upper edge corner of the carton 4 as the third transfer arm 11 begins to pivot forwardly toward the conveyer bucket 13. A stationary guide member 53 is positioned to form an extension of the guide part 37, when the second transfer arm 9 moves to an extreme downward position and, at such time, the third transfer arm 11 moves the carton 4 across the guide part 37, thence across the guide part 53, Fig. 1. The third transfer arm 11 continues to move the carton 4 whereupon the canton is seated in a bucket 13 of the conveyer 3 moving upwardly and being secured therein by the arcuate band 17, as is shown in Fig. 6. An arcuate skirt member 54 is positioned to engage and guide a side flap 25 of the cartons 4, should such flaps tend to fold backwards during the carton transferring operations.
A principal feature of the carton expanding apparatus of this invention not found in the carton expanders heretofore used is the inversion of the carton as it is removed from the magazine 5 and positioned in the buckets 13 of the conveyer 3. As is shown in Fig. 3, the cartons 4 must be placed in the magazine 5 such that the tuck fiap 26 extends from the top panel thereof in order that the finger member 31 will properly intercept the tuck flap 26 and may be inserted into the carton 4 when the carton is drawn downwardly from the magazine 5. As illustrated in Fig. 4, the carton 4 must be placed in the conveyer 3 with the tuck flap. 26 extending from the lower panel thereof such that the tuck flaps 26 may be folded upwardly and tucked into the carton 4 in a space above the articles contained therein. In the flap closure operation, an auxiliary blade (not shown) may be inserted and withdrawn to create sumcient space for the subsequent insertion of the cardboard tuck flap 26. With the carton 4, as positioned in Fig. 4, the weight of the articles exerted downwardly away from the space created by the blade will tend to preserve that space permitting the proper insertion of the tuck flap 26. Therefore, it may be appreciated that the cartons may best be expanded from a position with the tuck flap up in the magazine 5, and may be best filled and closed in a position with the tuck flap down in the conveyer 3. By use of the carton expanding mechanism as taught by this invention, the proper positioning of the cartons 4 may be maintained in both the magazine 5 and in the conveyer 3 since the carton expanding and transferring mechanism of this invention causes the cartonsto he inverted.
A further feature of this invention resides in the fact that the carton expanding and inserting apparatus is relatively simple, both in its structure and in its mode of operation. Because of its simplicity, the operation of the carton expanding and inserting apparatus of this invention will be relatively trouble-free and inexpensive to operate.
