Machines are known for shaping and closing boxes having slides or trays and in particular those for filling the slides of the boxes with cigarettes or like articles.

In such apparatus it has already been proposed to move towards one another the slide portion or tray and the shell or case into which it is to be pushed. The slide portion has been shaped during its movement and at the same time the cigarettes inserted in it. Moreover the initially flat shell in its movement has been. shaped (i. e. opened) so that on meeting with the shaped and filled slide portion it is located in the correct position to receive it.

Also it has already been recognized that the introduction of the shaped and filled slide or tray into the shell or case presents, difliculties and it has been proposed to feed the shells at an ane'le to the direction of movement to the slide portions therefor in such manner that one corner of the folded slide part first enters the shell.

The present invention. however. not-only solves the problem of simultaneously filling the slide and bending upwards the side portions but also the problem of introducing the slide into the shaped shell fed in the same direction in the longitudinal direction of the box.

For this purpose, While the cigarettes are being filled into the slide blank. the side walls are raised and later the completed slide is led on to an inclined track inclined towards the feed track of the shell .so that it first withits forwardly projecting front edge enters the shell. which is held at its opposite end by means which serve to erect (i. e. open) it. The blank broughtinto the feed track of the cigarettes is held by a Lil-shaped bridge falling on it whichrests on the bottom of the blank and at the same time permits-the introduction of the cigarettes and forms with its limbs abutment surfaces for the side walls adapted to be erected by cams or the like. The slide portions after the cigarettes are introduced and the side walls raised are led by the conveying means, while theslide is at the same time completely closed. into a channel in. which the slide portions are fed forwards in the new apparatus. 7 section. on the line 33 of Fre. 4 to an 'en- 36%,833, and in Germany March 5, 1928.

the longitudinal side of the box or packet into a channel with an inclined base the cover of which is formed by the lower flight of an endless conveyor band rotating in a suitable di rection. The last part of the inclined base of the channel is inovably arranged and operated in such manner that the slide part which passes on to this base portion is led in an inclined position to beaks withthe shell fed oppositely to'it, whereupon the base portion is lowered in'such manner that the slide part is coinbined with the shell lying wholly in the same plane. The initially flat shell "is pushed forward over a former which presents to the shell first a knife-like end and gradually expands to the'internal cross section of the erected shell; the shell beingfed forward by feeding means engaging the outer side thereof and means being. provided for preventing the former from being displaced so as to permit the passage of the shell on to the former. The insane for preventing the former from being displaced consist of a number of pins disposed in a row and in the longitudinal direction of the former, and movable towards the former, which pins with their ends are adapted to enter recesses in the former and are so operated that they are moved in succession corresponding to the feed of the shell upwards out of and'downwards into the recesses in the former.

The invention is illustrated in the'accompanying drawings which show one example of apparatus for boxes having slides ortrays filled with cigarettesn i 1 shows the new apparatus in side elevation partly in vertical cross section on the line 11 of Fig. 2. Fist. 2 is a plan view of t Fig. 3 shows in cross" lare'ed scale the part shown at the left hand side of Fig. 1. Fig. 4 shows in plan also to enlarged scale the portion shown at the lower left hand side of Fig. Both figures refer to the arrangement for introducing the cigarettes and at the same time erecting the side walls of the slide. Fin. 5 shows the central part of 1 to enlarged scale. Fig. 6 is a plan view thereof. Fig. 7 shows in vertical longitudinal section the part of the apparatus which serves to connect the two parts of the box. Fig. 8 is a plan view. It will be observed that Fig. 7 is a vertical section on the line -5 of Fig. 2 to enlarged scale.

Figs. 11a to 11 a show the slide parts and the box shells in different stages of production.

, The cigarettes 2 2 are taken from the containers 1 and 2 by drums 3, 4 and delivered to feed bands 5 and 6 which feed them laterally of the track 7, the cigarettes being depositedin two layers on the track 7. For

this purpose a strip 8 is provided. which is '7 upper finger of which is fed over the strip "8 While the other finger moves between the strip 8 and the track 7. The upper finger of the pushing device feeds the cigarettes a to the end 11 of the strip whereupon they are deposited on the lower layer formed of the cigarettes 2 Both lavers of cigarettes are now pushed by the fingers of the pushing device and fed to'the slide blank'or tray blank beneath the U-shaped bridge 12. The pusher. 9 is a bifurcated member of the construction shown in the copending ap lication Serial Number 449,822 of Neff filed May 5. 1930. This pusher while swing ng around with the chain to which it is attached will longitudinally displace the two levers of cigarettes relative to one another. To re store them to the proper position on the slide blank before the latter can be folded. as will be presentlv described. an additional pushing meansisused. This pushing means comprises a plate 50 capable of swinging in ver tical direction an'd formed with a wing or part 52 adapted to be actuated by suitable means (not shown). After the positioning of the cigarettes onto the s ide blank the plate 50 is swung downwardly against the ends of the cigarettes and thereby ushes them back to be in alignment on said slide.

; -.The slide. blanks s are arranged in iles in the holder 13. Beneath the holder slides to V and fro a pusher 14 having a lug 15. A lever 16'pivoted at 16?) to the machine frameis fitted with a roller 16!; which tracks a cam disc 17. The lever 16 is controlled by a spring 16a and engages with its forked end 16d and a pin 14a secured to the pusher 14. The pusher is moved to and fro by this means in such manner that on each stroke it withdraws a blank from the holder13 and -pus-hes it on to'thelconveyor band 18. As

soon as the slide blank abuts against the stops 177) 3 and 4) the U-shaped bridge 12 is lowered thereon. At the same time the charge of cigarettes is pushed beneath the bridge; at the same moment the pushers 19a move upwards and raise the side walls wet the slide blank (Fig. 11a). Preferably, the pushers19a and the stops 19?) are mounted on a common frame" 19. This frame is moved from a-cam disc 20 by means of a double armed lever 20a and a link 20?) so that the stops 19b first stop the slide or tray and hold it and then the pushers 19a asabove described move upwards and raise the side walls w. Thereupon the'pushers 19a retreat and the stops 19?) move downwards and release the slide. At the same time the bridge '12 moves upwards. the Xed stamp 12a pushing the slide out of the bridge. The pushing member 21 of the conveyor band 18 comes against the filled slide and pushes it through the channel 22. This channelis provided with flanks 23 and 24 which raise the flaps (Fig. 11a) of the slide or tray vertically and bend .over' the tongue .2 so that it' lies parallel to the bottom of the slide. r

When the slide or tray reaches the end of r the channel 22 it is moved by a pushing member 25 which is moved by a chain 26 over a track 27 at right angles to the longitudinal direction of the channel 22. 'Thismember pushes the slide or tray through a'short channel 28, the folding plates 29 folding the flap 7c of the slide into its horizontal position and bending over its sides I? (Fig. 11a) so that the slide is given its finished form. After the slide has passed through the channel 28 it passes on tothe steep inclined plane 30 and beneath the lower flight of the conveyor band 31 and is fed in the direction of the arrow a in Fig. 7 towards'the shell of the box/ The flat pressed shells or cases h of the boxes'are piled in a holder 32. Pushers 33 extend through a slot in the bottom of the holder. these pushers being carried by a chain 34 and carrying with them' on their passage beneath the holder 32 a shell and feeding it in the direction of the arrow (Figs. 7 and 9). The wedge-shaped core or former 35 with its knife-like end 36 enters the openings in the shell. Several such shells h are adapted to continuously engage said former 35 at a time, thereby supporting the former 35 in its position at the desired height from the path of the shells h. The former 35 gradually increases in dimensions until it has the full internal width of theshell and a corresponding rectangular cross section. The shell is thus shaped and opened while it is carried over 1 the pins 38 alternately engage. These pins under the action of springs 39 are pressed with their upper ends against cams 40 which are mounted on the cam shaft 41 and actuate the pins in such manner that the former is always held by'at least two pins. During the passage of the shells over the former, each pin is raised in turn until the shell has pushed past beneath it. b

At the moment when the slide or tray 8 reaches the position shown in Fig. 7 the shell h of the box meets it, the upper front edge of the slide being pushed a little into the shell. At this moment the movable part 42 of the steep inclined plane 30 is turned about the pivot 43 into the horizontal position while at the same time the pushing member 33 pushes the shell part of the box over the slide. The part 42 is actuated by means of a cam 4A and a spring 45.

The completed box is pushed by a pushing member 46 which hangs from a chain 47, on to a conveyor band 48 which runs parallel to the chain 44 but in the opposite direction thereto and delivers the filled boxes from the 7 machine.

Figs. 11a to 119 show the different stages of the boxes. Fig. 11a shows the slide blank as it comes from the holder 13. Figs. 11?) and 110 show the slide before and after its passage through the flanks 23 and 24:. In Fig. 11d the slide is shown in its finished form. Figs. 116 and 11;" show the shell in half and in completely erected position. Fig. 11g shows the finished and filled box as it leaves the machine on the band 48.
