CARTON-FEEDING DEVICE.

Application fil ed October 16, 1922, Serial No. 594,796. Renewed July 29, 1926.

10 pared and sh pped fiat involves certain inherent diiiiculties in getting it from its flat or folded state into its erected or opened up position by mechanical means.

This difiiculty is primarily due to the natural set given to the cartonwhile in its fiat state with the folds at d' onally opposite corners, creased hard they naturally become when closely packed together and the opposite corners flattened out. T his set in the folded carton naturally malres it tend to sta-v closed and to return to a closed or partly collapsed condition after it is opened up.

i It is obviously of great importance that the carton when set up be as truly rectangular possible. The problem of handling has been variously treated in the art and a variety of opening up mechanisms have been devised. V

0 My present invention includes in part certain novel instrumentalities and combinations by which a maximum of accuracy and speed is obtained w.t-h a minimum of waste due to tearing), and crumpling of the paper cartons.

This with various improvements in the feeding of the cartons to the opening up point and their subsequent delivery for sue (ceding operations according to my present invention may best be understood by reference to a practical embodiment and I have therefore shown in the accompanying drawand will describe in the following specification a ma ....ine whivl'i have tested out and which in accordance with my invention and well illustrative thereof.

Fig. 11 is a fragmentary plan view of the cross slide in its transferring movement, and

Fig. 12 is a detail of the carton follower.

In the embodiment of my machine which I have shown in these drawings as illustrative of my invention, mount on a base 1 a slide frame or head 10 on which and on the base 1 are mounted slides and 30.

The base 1 is formed with an overhang 1 as will be seen in Fig. 3, which supports the head 2 transversely of a conveyorfram'e 40 along which the knock down or flat cartons are advanced to the transfer slide 20. The conveyor 41 is of the chain feed type running on sprockets 42 to advance the vertically disposed pack of cartons longitudinally-of the frame 40 and between the rails sup: ported on uprights 44 at each side of the way. The rails 43 are disposed two on one side of the conveyor 41 and one on the opposite side, the odd rail being; disposed about midway the heightof the two opposite rails so as to give a three point support for the. stack of cartons as they move past.

The sprocket 42 is advanced by a ratchet drive comprising a ratchet mounted fast on a shaft 51 and turned by a pawl 52 car- .53 and M anglesthereto. The rod 62 has a forked end ried by an arm 53 loosely mounted on shaft 51. This pawl is reset by an eccentric 60 on a shaft 61* througih a rod 62 which is connected to an arm 54. integral with the arm disposed at substantiallv right which embraces the eccentric 60 and is engaged thereby whenever the rod (32' lowers it. The arm 54 is also connected with a spring 55 fastened at 56 to the base of the machine and tending),' to rockthe pawl arr 53 and thus turn the sprockets 4-2 to advanvie the carrier 41. This spring 55 constitutes predetermined motive power to the conveyor drive.

The return motion of the ratchet is effected by the eccentric 60 which resets the paw-loathe main power shaft 61 whenever the transfer slide has reduced the number if cartons sufliciently to allow thespring to draw down the arm 54 so that the eccentric 60'finds bearing at its bottom. thus resets the ratchet to advance the carrier under the action of the spring whenever the reduction of pressure adjacent the transverse slide permits the action of the spring 55. i

The spring 55 therefore keeps the pressure within predetermined limits on the blanks in advance of the follower as. This follower 4-5 consists of a heavy block hai pins M3 in its lower face which engage with each of the conveyor chains 4-1. As the cartons are'placed on the conveyor the block 4e5zis placed behind them a follower to hold the cartons erect and to insure their advance and their free presentation to the transfer. slide 20.

Referring to Fig. 7 whica is a plan view of the transfer slide head with the brackets 1-1 removed, the slide 20 is gibbed into a way 21 the entire width of the frame. It is reciprocated along this way bv a lever having a forked end71 which receives between its jaws a block 72 which is loosely pivoted. on a stud 3 carried by the slide 20. V The lever 70 is pivoted at i l to the bracket on. the base. 1. It carries at its lower enda roller 75 whichv runs in .a cam. slot 76 on a cam 77 which is fast on the power shaft 61. Mounted on astud is a bracket 80 carrying an adjustable stud 81 which is disposed to strike a. jogger lever 82 pivoted at 83 and normally held up towards the bracket by aspring St. This spring; 84- is fastened at 85 to a bracket and at 86 to a hook which projects out from The receiver casting 90 is pivotally mounted at 93 to bracket 9-1 which 1s mounted on the slide head 10. it is held in position by a loose bolt 95 which can be released readilyin case of a jam in the carton receiver. in such an event the casting" fill may be swung on its pivot 93 and the iti'nmed cartons removed without trouble or delay.

To the rear of the diagonal line between the

corners

91 and 92 the receiver hollowed out as at 96 so that the carton as m d eated at (l is free to expand rearwardly as well as forwardly. This is important as the nature of the opening blade ltltl expands the rarton slightly while still in its initial position asiu Fig". 8 and it is important and l have discovered that it is important to permit the carton to expand symmetrically in both directions in order to avoid distortion and possible tearing.

The lower side of the carton receiving pocket is closed by a plate 110 which is slotted at 111 for the position of the blade 100. In its upward position the blade Hill is guided by a. similar plate 110 which proiects above the pocket men'iber 90. The blade 100 is carried in a slide 101 mounted in a slideway 102 adjust-ably held to the. slide 101 by bolts 1th.. The slide 101 is vertically reciproci ted by a link ltlil vow nectcd to one arm ll tl: with a bell crank pivoted at 105 and having its opposite end provided with a roller 106 ninnir in the cam groove 10'? of the cam 108.

This cam is fixed on the main shall G1. The shatt 61 1s driven by a sproeke (32 a t one end and at its opposite end has a hand wheel 3 by which the machine. may be turned over by hand when so desired.

The slide 30 carrying the vertically tociprocating blade 100 is itself reciprocated at right angles to the transfer slide 2) by a lever 31. The lever 3i is slotted as at 132 to receive a block held by a stud 3.4 to the slide 30 so to vary the throw of the lever with the motion of the slide. The lever is pivoted at its lower end as at 36 and is rocked by a roller stud 8T runningin a. cam groove in the cam 38 also fast on the power shaft 61.

It will therefore be seen that in this grou p of parts last. described, the bladelOO can be raised past the plane of the plate 110, projecting through the slot .111 so as topenelid wtrate the fiat carton C substantiallyin the line of that one of its flattened out corners which lies facing forward or in the direction in whichit is advanced.

\Vhen the blade 100 enters the carton C at this point it begins to expand it. The carton being held by its edges as above described is free to expand in both directions of its opening movement so that when the blade 100 has passed through it, it is symmetrically opened up with theblade against the inside of whatis to become one of its corners, but which up to this time has been pressed flat.

The slide now moves forward advancing as the blade 100 which moves the carton out of the

opposite corner

91, 92. between which it has been held. (See Figs. 8 and 8); As appears in the latter figure it will be notedthat the carton C has been brought in contact .with a pair of guides These guides converge at first but later become parallel so that the inner corner of the carton meets a slight resist ance or drag which tends to swing the ad jacent panel about the edge of the knife as a pivot to a position at right angles to that which it occupied when flat. As the blade moves forward this panel traveling against the parallel face of. the guide 120 meets no resistance while the forward edge of the opposite panel being still in engagement with the guide face 121 is retarded. In this position as shown in Fig. 8 the carton is opened out past its normal rectangular posi-' tion so that the folds or corner-scorings -which have been flat prior to opening are given a fold or set in excess of that which is desired. The corners, which have been sharply folded when the carton was flat,

are opened out at a more obtuse angle than their ultimate position so as to counteract the tendency of the carton to return to the flat condition in which it wasoriginally.

At the end of the movement of the slide 30 along its slideway 39, the blade 100 reaches the inner corner of the carton pocket 140. For the purposes of the present disclosure this pocket need only be considered as one of a plurality of successively presented pockets each adapted to take an openedcarton in turn. They are in fact, in the embodiment shown the receiving pockets of an end flap closing mechanism with which this embodiment is especially adapted to operate.

Fiach pocket 140 has one of its lateral walls 14-1 pivoted. at 142 which is opened by a roller M3 which is moved vertically as indicated by the arrow in Fig. 10 to a position in. which it contacts with a tail 144 on the pocket wall. This wall is opened as the blade 100 approaches with the carton trail- 'ing thereon.

When the blade reaches the corner as shown in Fig 8 the trailing panel clears the end of the guide 121 and under its own natural tendency this side snaps forward into the pocket. The seating of'the carton G in the pocket is assured by the spring pressed return of the wall latl which snaps nst the edge panel and about its corner. The wall 141 has an overhang lip 1 which closes about the outer edge, thus holding the carton in position and at the same time giving it a slight diagonal pressure in the direction of the blade, thus completely as suring the completeness of the angular coincidence between the carton and the corners of the pocket.

At this point the blade 100 retreats. being lowered along this slideway 102 under the action of a cam 107 through its bell crank and link connection. As soon as the blade has cleared the plate 110, the slide 30 is returned by .its cam 38 to its original carton penetrating position beneath the pocket 90. in the meantime the transfer slide 20 has 'vanced another carton to be opened and no. 'tioned it with its edges in the corners 9i; and 92.

The details of the pocket90 and the carton engaging edge of the slide 20 are shown in the enlarged fragmentary view of Fig. 7. In this view it will be seen that the

edge receiving portions

91, 92, referred to gen erally as the corners are defined by one wall of the guide 120 and a pair of catches 122 which are just behind the carton when it is delivered into the pocket 90 by the action of the springs 122 which permits that the pawls yield upon the advance of the carton which pushes them out of its. path as it is moved forward with the slide. The edge of the slide 20 is providedwith a lip 20 carefully formed to the exact thickness of the folded carton'edge so that it will pick the carton from the end of the pack in the carrier and advance it along the slidevwav to. the carton receiving knife.

In order to have the transfer slide 20 accurately and evenly engage the edge of the most advanced carton in the pack and remove it thereform without danger of crumpling or tearing it, it is necessary that the blanks be presented with a uniform pressure as maintained by the ratchet connection and the spring which keeps the conveyor block or follower 15 up against the carton pack. The tension on the spring 55 is restored at frequent intervals by the eccentric which constitutes a continuously acting urge although, through the pawl and ratchet connection. the conveyor is only driven intermittently.

It is also important that the cartons be presented in the proper position and that the pack adjacent the transfer slide be squared up and even. This is partly accomplished by the disposition of the rails 43. As above described, there are two of the III at: 154 is pivoted a rocker rod 1-541.

rails on'one side and the third on theopposite side thus affording a three point line of contacts; The. action or the jogger 82 restores the alignments of any cartons that may possibly be irregularly positioned in the pack. At each stroke oi the cross slide the tail of the lever strikes the side of the carton pack just atter the carton has been removed from it, thus assuring not only the alignment of the cartons but thei freedom to 'move up promptly behind the conveyor slide under the pressure of the conveyor driving spring 55.

Extending across the head of the machine "and jourualledin brackets 11 is a shatt 150 Adjacent lever 'lol and also fast to shaft 150 is a short arm 153 on the end of which This rod is pivoted at its lower end to a rocker The rock r 155' is pivotally mounted at 155% and carries a block 156 to which is pivoted at"1"57 a slide 15; to operate in the slideway' 158 of the guide 43 Suitably mounted within the slide 157 and shouldered'to receive-a compression spring 159 is a carton urger 157? operated by the upwardth'rust ot-the lever 1524 to oscillate the rocker 155 around pivot 15532.11 disposed to advance the slide 157, by which means the cartons ahead of the carton urger are also advanced by contact of carton urger to facilitate their 'delivery to the slide as shown in Figs. 10 and 11.

hen the conveyor l]. is advanced by operation of the ratchet drive to advance pack towards slide 20, the cartons contacting with the-back side of the carton urger 157 slide alongthe' angular surface 157 of the carton urger compressing the spring 159., as shown in Fig. 7, and travel the predetermined distance, after which the carton urger returns to an operative position by the ex pension of the spring 159.

\Vh'ile I have referred to the machine herein shown in some detail as to mechanisms; it will be understood that many of the .mechanisms niay be varied and modified or other equivalent mechanisms substituted. All such modificat ons are to be understood as within the scope of my present invention, and while {I have referred to my machine particularly for the handling of cartons, many ot'its novel features may be utilized in feeding other flat blanks or pieces of stock for subsequent operations.
