APPARATUS FOR USE IN FITTING TOGER some OF THE SLIDE =1- snnnr. m3.

Application filed December 2,1926, Serial No. 152,296, and in Great Britain December 8, 1.

This invention is for improvements in or relating to-an apparatus for fitting together boxes of the slide and shell type and has for its object the provision of means whereby a shell may be opened from its collapsed state so as to receive a loaded slide without the possibility of the same fouling the shell.

The present invention consists of a device for use on a machine for assembling the slide to open the shell for the reception of a slide.

The invention is more particularly described with reference to the accompanylng drawings, in which Fig. 1 illustrates in plan the layout of a machine constructed to assemble the packets of the slide and shell type.

' Fig. 2 is an enlarged plan view of one method of opening the collapsed shells.

Fig. 3 is a side elevation on the line A- -A. of Fig. 2.

Figs. 4 and 5 illustrate details of the valve mechanism used in conjunction with the suction device illustrated in Figs. 2 and 3. Fig. 6 illustrates mechanism adapted to feed the collapsed shells towards the suction mechanism, and

Figs. 7 and 8 illustrate in plan and elevation a modification of theapparatus illustrated in Figs. 2 and 3.

Referring to Fig. 1 the slides 2 are placed ina stack in a magazine 4 which is arranged on one side of a conveyor 1 and comprises side members 4, front members 5 and 6 and a bottom in the form of a reciprocating table 7. Thetable is reciprocated y means of an eccentric, driven from the main drive of the .machine in the manner described in U. S.

Patent No. 1,473,496. At the rear-edge of the table is .a pusher tooth 12 which passes through an opening to the back member 6 and upon the movement of the table moves one slide at a time from the bottom of the stack to a pair of continunsly rotating rollers passes to a further pair of rotating rollers 15 In this with cigarwhich deliver it on to the conve or. position the slide may be fille etts in the manner described in U. S. Patent No. 1,188,368. In Fig. 1 a machine is illustrated with a batch of cigarettes delivered on to the slide 20, with a succeeding batch 21 located on a conveyor 16 which moves the cigarettes towards the conveyor 1.

When the loaded slide 20 is in the position illustrated in Fig. 1 the cross piece 1 mounted on the conveyor 1, makes contact with the rearwardly directed upward edge of the slide and carries the same through an L shaped channel 22 and suitably curved plates 24 which fold up the two end pieces 25 of the slide approximately into a vertical position and thereafter bends the said ends into approximately a horizontal position ready for the slide to be inserted in an 0 en shell. The slide so folded is then carried y the conveyor into the position for insertion into a shell.

The collapsed shells B are stacked in a magazine 27 on the same side of the machine as the slide magazine. The magazine 27 is of a similar construction to the slide magazine and is provided with a small reciprocating bottom and pusher tooth for feeding the lowermost collapsed shell between continuously rotating rollers 28. The rollers 28 pass-the shell between a continuously rotating sector 29 (Fig. 6) and one edge of the shell engages with an arm 30 pivoted at 31 and pressed into engagement with the shell by a cam 32 engaging with a finger 33 on the arm 30. The action of the sector 29 and the arm 30 causes the shell to be moved into a position inclined to the direction of the conveyor 1. The shell is moved into the inclined position against a guide stop 33' above a suction element 34 which is connected to a suction pump (not shown) through the valve mechanism illustrated in Figs. 4 and 5. The valve mechanism illustrated" in Figs. 4 and 5 is controlled by a cam 35 operable from the main drive of the machine and timed so as to bring the suction element 34 into operation when the shell is correctly disposed above the same.

=- Referringto Figure 1, it will be seenthat the shell is moved into an oblique position so that when it is opened the mouth of the same 1 will lie transverse tothe path of the on-com-- ing loaded slide, whereupon part of the slide 3 enters the-mouth of the shell in the manner are." illustrated in Figure 2without 'necessitat .a transverse movement of either the shell or;

13 which feed the slide between suitably 'curveol-dplates 14 which bend upithelongitu gas of the slide, after which the slide ment 36 is also the slide, and without requiring that the slide cease" its steady forward movement. After the parts are positioned as shown in Figure 2, the slide carries the shell forwardly and the same is automatically inserted over the slide by mechanism which forms no part of the present invention. It is an important feature of this invention that there is imparted to' the loaded slide a steady forward movement in contradistinction to the usual step by step movement in devices heretofore known,

When the suction element 34 comes into operation an upper movable suction elerought into operation and engages with the upper broad side of the shell and adheres to the same due to the action of the valve mechanism hereinbefore described. After the upper suction element has been brought into operation a bell-crapk lever 37 operable by cam 38 driven from the main drive of the machine rocks the lever "39 to cause the s indle 41 to rotate about its axis. Secured ast to the spindle 41 is a link 42 which is connected to the arm 43 which carries the suction element 36. On the upward movement of the link 42, the arm 43 1s moved upwardly and carries with it the upper broad side of the collapsed shell. The arm 43 is preferably connected to link 44 which is similar to the link 42 and ensures that the arm 43 is given a parallel motion. The free end of the lever 39 is connected to a ring which, when the cam 38 has raised t e arm 43 into its highest position, tends to draw thesaid arm downwardly.

When the cam has caused the shell to be opened out into its maximum position the valve controlling the suction members is opened and the suction members become inoperative. After, the suction members are released the cam 38 tends to raise the arm 43 still further, but due to the fact that the end of the arm 43 which is connected to the link 44 is fixed and the intermediate point which is connected to the link 42 is secured thereto throu h a spring connection 45, the arm 43 is ed about the pivotal connection between it and the link 44 and the suction element 36 is raised above the upper surface of the shell so as not to interfere therewith as the slide and shell are removed by the conve or 1.

vided with an adjustable sto coming slide will be easily inserted into the shell. The shell and the slide are thereafter assembled in the manner described in U. S. Patent No. 1,47 3,496 and the assembled packcontinuation of the lower broad side when the shell is in the collapsed state. The suction element 34 is adapted to dra the shell upon the bed of the machinealong the entire line which constitutes the junction between it and the adjacent wall and thereby removes any bow that may exist upon the underside of the shell.

- Mounted above the lower suction element 34 is a plunger 50 connected to links similar to those described with reference to Figs. 2 and 3, so that when the plunger is depressed it presses upon the upper surface of the collapsed shell and also permits a hook shaped projection 51 to engage with that narrow side wall of the shell which lies flush with the lower broad side of the shell. 1

The projection 51 on the end of the lunger 50 engages with the narrow side wal of the shell and swings the same upwardly about the junction line until the two narrow side walls of the shell are located at right angles to the lower broad side of the shell.

When the shell is in this position, the formost corner of the advancing slide enters the inside edge of the shell and together with the conveyor 1, the slide and shell are moved forwardly and the slide and shell assembled in the manner described in U. S. Patent No. 1,473,496.
