CIGARETTE AND CIGAR TRAPPING MACHINE.

Application filed June 8, 1925, Serial No. 35,594, and in Cuba January 24, 1925.

This invention is an in'iprovement in wrapping machines, and more particularly in machines for compactinga selected number of articles, such as cigars or cigarettes, intoa formation substantially rectangular in cross section, irrespective of the cross sectional shape of the article.

In a certain type of wrapping machine for articles like cigarettes and cigars, the ar ticles are assembled in blocks of a selected number, and wrapped in a w'apper, the folding of which about the block of assembled articles is controlled to operate by the-movement of the assemblage past the folding .mechanism.

The articles are usually massed or bunchedwby discharging a selected number from a magazine, either the full complement of articles, or an aliquotpart thereof. In the latter case a distinct operation of ejection is required for each aliquot part.

With articles which are cylindrical or circular-in cross section and of uniform dimensions, it is notdiflicult to eject from a magazine a. selected number; When ho vever the articles vary in size, and especially whenthey are "not circular in cross section, the ejection is not so easily carried out.

At the present time, cigars and especially cigarettes difier greatly in cross sectional shape, and with oval cigarettes and cigars, methods of ejecting a selected number from the magazine are not satisfactory, and when ejected the articles do not lie compactly.

One of the primary objects of the pre ent=invention,'is the provision of mechanism forsimultaneously ejecting from a magazine thealiquot partsof a selected number of articles, such as cigars or cigarettes, and for afterwards bunchingthe parts in a compact block, wherein the parts are superposed one upon the other.

Another object of the invention is the provision of means for similarly arranging a set .of articles of similar shape and size-but oval in cross section.

'To the accomplishment of the foregoing and such other objects asmay hereinafter appear, the. invention consists in the constructionand novel combination of parts fully, described hereinafter, illustrated in the accompanyingv drawings, and pointed outinthe claims appended hereto, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims, may be resorted to without departing from the spirit of the invention.

In the drawings forming a part hereto,

Fig. l is a front view of the magazine, at substantially the line l1 of'Fig. 3.

Figs. 2, 4 and 6 are sections on the lines 2-2, 4-i and 66 respectively, ofFig. 3.

Fig. 3 is a plan view.

Fig. 5 is a perspective viewof one of the discharge chutes for the magazine.

Fig. 7 is a view similar to Fig. 6 showing the parts in another position.

The present embodiment of the invention,

which is adapted for use in connection with the machine forming the subject matter of my co-pending application Ser. No. 35,593 of even date herewith, comprises a magazine with a bottom composed of three chan nels, 1, 2, and 3, the bottoms of the channels being in stepped relation as shown, with the bottom of the channel 3 at the highest level. The channels 1 and 3 are adapted to receive articles from the body 4 of the magazine, and in the bottom of each channel means is provided for segregating a plurality of articles, and for holding them in spaced parallel relation.

Each of the said means is constituted by a number of partitions 5, which form between them and the walls of the channel, a number of troughs, each for receiving a single article. Where it is desired to pack the articles in superposed rows of aliquot parts of a selected number, as for instance 10 cigars in two rows of live each, there are five troughs in each channel, but the number of troughs will depend upon the number of articles it is desired to pack in each row.

Deflecting plates 6 of angular formation are arranged at the outer sidesof the channels, for deflecting the articles placed in the magazine into the channels. An areshaped deflector 'F is arranged between the channels, above the channel 2, and these deflectors are supported by aframe 8 which is mounted for transverse sliding movement between the body of the magazine and the channels.

It will be noticed referring to Fig. 2 that each of the deflectors 6 has a portion eX- tending through a slot 9 in a magazine wall, and a lever 10 is'provided for vibrating. or

reciprocating the "frame, the lever being connected to the frame by a link 11. The deflectors 6 are perforated as shown, and the frame is a species of grid, being composed of side members slidable in guides in the front and rear walls of the magazine, and connected by cross bars 12 at the inner ends of the deflectors 6, and at the ends of the deflectors 7, and by spaced pins 13 between the deflectors.

The pins 13 are spaced apart at equal distances, and at distances somewhat greater than the spacing of the partitions 5. The arrangement is such. that the articles in the magazine will be fed down between the pins 13, into the channels, with their 1on9; axes parallel with the pins and the partitions, and the articles will fall into the troughs between the partitions. These troughs are of a size to hold a single article. and any desired form of pusher is provided for ejecting; each series of articles from the channel.

The pusher for each channel may be a se ries of fingers. corresponding in number to the number of troughs, and moving through an opening 14': in the rear wall the magazine. Referring to Fig. 4 it. will be seen that a door 15 is provided in the side wall. the door being hinged at 16 at its top, and at its lower edge the door carries a number of fingers 17. which at their lower ends are in rear of the partitions 5. The fingers prevent the escape of articles at the rear of the magazine.

In front of the magazine and spaced apart therefrom, mechanism is provided for compacting the articles of each row, and for moving the rows laterally toward each other, into position one above the other. The said means includes a casing 18 which is supported on the table 19 which supports the magazine, and this table may be the frame carrying the wrapping mechanism shown and described in the application above mentioned. The casino: has its long: axis transverse to the path of movement of the articles issuing from the magazine, and it is provided with two passages or channels 20 and 21 extending entirelv through the casing from front to rear, and from one end thereof to near the other. One channel 20 extends from the left end of the casing, and the other from the right end, and they lap at their inner ends as shown, in Figs. 6 and 7. i

A slide is arranged in each of the channels, the slides 22 and 23 being movable toward and from the inner end of the respective channel, and cooperating; with the said inner end thereof, to compact the articles delivered into the channel. Each of the slides has connected thereto a pin 24 and 25 respectively, and the pins move in slots 26 in the casing. Levers 27 are connected with the pins by means of links 28, and it will be evident that when the levers are vibrated. the slides will be moved longitudinally of the channels.

The bottom of each channel 20 and 21 is formed by a plate 29 and 30 respectively, and these plates are connected with the slides, the plate 29 to the slide 22, and the plate 30 to the slide 23. The plates move on the bottoms of" the channels, and when articles are delivered into the channels in a manner to be presently described, they are delivered onto the plates.

i hen the cigars or cigarettes are cylindrical. they may be delivered into the channels 20-21 in any angular order. That is the angular position of the several articles is immaterial. l Jhen however the cigars or cigarettes are oval in cross section, it is desirable in the formation of a symmetrical package that the long; axes of the oval cross section be parallel and inclined. to the vertical. In order to insure that they will be so arranged in the channels 2021, mechan sin is interposed between the troughs of the magazine, and the channels, that is between the inagazine and the casing 18.

The said mechanism is for each set of seeregating troughs, a set of tubular guides which tor convenience are assembled in an integral structure comprising a base 31 and a nozzle portion 32 extendinglaterally from the base. and provided with bores 33 corresponding in number to the number of troughs. The base is secured to the tront wall of the casing, at the front ends of the troughs. and with the bores 33 of the nozzle in register with the troughs. Each of these bores as shown in Fig. 5 is circular in cross section at its entrance end, and oval in cross section at its discharge end, id each bore tapers from the entrance to the discharge. The walls of the bores are of a nature to otter no resistance to the passage of the articles. but the articles receive an angular movement in their passage through the bores. in the same direction. so that thev emerge with their axes parallel and inclined. The pnshers 34 which mo e in the channels. pass on opposite sides of the plate 29, the upper pusher moving the upper row of articles into the channel 20, while the lower pusher moves the lower row into the channel 21.

At this time the slides 22 and are at the outward limit of their strolre. and the articles of each set are moved into the appropriate channel between the front end ot the slide and the closed end of the channel. When the machine is handling articles oval in cross section, the front ends of the slides, and the closed ends of the channels should be beveled as shown in Figs. 6 and 7, on lines parallel with the lona axes of the ovals.

lVhen the articles have been placed in the casing as above mentioned, the slides are moved toward the inner walls of the channels, and each set of articles is compacted between the inclined walls of the slide and channel ends. The articles are not pressed tightly, but merely massed, and held in the desired relation.

At this moment the pushers 84 move forwardly, ejecting the compacted cigarettes from the channels -21, into the wrapping channel of the machine forming the subject matter of the above mentioned application. The slides are then withdrawn, another charge of articles is inserted in front of each slide, and the operation is repeated.

The pushing fingers which move the articles out of the troughs need only be of a length to push the articles from the troughs. The next movement of the fingers to eject another charge of articles, will eject the first charge from the mechanisms 32.

In operation, the articles are fed into the magazine, and by means of the reciproeating grid they are dropped into the troughs of the channels with their axes parallel, and in segregated relation. By means of the pushers not shown, the articles in each set are shoved out through the structure 31-82, into the channel 20 or 21 as the case may be. VVh-en the slides move toward each other, each set of articles is com pacted, and by the pushers 34, the com pacted sets are moved out to the wrapping channel, or they might be moved directly into a suitable container, as for instance a box if desired.
