This invention relates to combined scrap bunch rolling and shaping or concentrating machines, particularly to one in which a number of operations hitherto performed by hand are carried out in greater part or wholly by machine,

with the object of speeding up the manufacture of the cigars, and improving their quality.

'Scrap bunch machines have been limited as to speed because of the time required for the binder girl to lay a binder on the rolling apron and to transfer the rolled bunches from the bunch rolling machines to the bunch shaper or concentrator.

.the mold pocket of g In laying the binder, the binder girl has to locate the binder in proper position relative to I the filler charge in the bunch roller apron pocket. In order to make sure that the hastily laid binde-r fully enclosed the charge of scrap, it has been necessary to use extra large binders resulting in a considerable waste of binders.

Even with this precaution, the binder is sometimes placed too far to one side, with the result that the scrap has been lost from the head or tuck end of the cigar bunch and the cigar has therefore been rejected. It is an object of the invention to produce a scrap bunch machine which obviates these difflculties.

a transfer of this type which will not interfere with the preliminary constricting or shaping of the bunch as it is placed in the pocket of the bunch shaping unit, and will permit substantially full length shaping without slots or notches to admit transfer fingers.

'Another object of the invention is to combine with scrap paster which will serve during subsequent operations or bunch rolling mechanism, a binder to keep the binder closed transfers, thus preventing loss of the scrap through opening up the binder and which will also produce bunches which are more uniform as to size for the same reason.

Cigar machines,

whether of the scrap or long filler type have either required hand feeding of filler or else the placing of binders by hand with the restricted output due to the of the binder girl referred to above.

automatically cutting to shape and transferring and locating of binders relative to the charge automatically supplied to produce a machine.

Thus it is an object of the invention. to produce a machine which is more automatic than any cigar machine hitherto produced requiring a, minimum amount of labor and having the maximum speed for machines of this type which machine because of this makes scrap cigars of improved quality due to the more uniform feeding of tobacco and more accurate placing of binders and resulting more certain enclosure of scrap therein.

Another object of the invention is to combine the above with fully automatic transferring of the rolled bunches to the shaping and wrapper applying machine and to insure against loss of scrap from the ends of the bunch during this transfer.

Thus in the new machine all that will be required of the operator at the bunch forming end of the machine will be that she spread a leaf on a leaf cutting die and all other operations preceding the supplying of a wrapper in the wrapping end of the machine will be performed completely by machine.

With these and other objects not specifically mentioned in view, the invention consists in certain constructions and combinations which will be hereinafter fully described and then pointed out in the appended claims.

In the accompanying drawings, which form a part of this specification and in which like characters of reference indicate the same or like parts, Fig. 1 is a diagrammatic plan view of a combined scrap bunch rolling and shaping machine embodying the present invention; Fig. 2 is a side elevation on line 2-2 of .Fig. 1; Fig. 3 is a side elevation on line 3-3 of Fig. 1, showing the transfer for mechanically taking a bunch from the rolling unit and depositing the'same in the loading carriage of the bunch concentrating unit; Fig. 4 is a front elevation on, line 4-4 of Fig. 3; Fig. 5 is a top view on line 5-5 of Fig. 3; Fig. 6 is a side elevation on line 6-5 of Fig. 1, showing the operation of the transfer mold of the shaping unit; and Fig. '7 is a front elevation on line 1-1 of Fig. 6, showing the actuating means for opening and closing the jaws of the transfer carriage.

' In carrying the invention into effect there is provided in combination with a bunch shaping device, a bunch roller which operates to roll filler tobacco into a binder with the binder projecting beyond the filler together with mechanism for transferring bunches from said roller to said device including two laterally spaced sets of grippers arranged to grip the projecting end portions of the binder to prevent scraps of tobacco from escaping from said ends. The best constructions will also include full length bunch shaping means acting on the bunch in the space between said sets of grippers. The best constructions will also comprise the combination with bunch rolling means including an apron having a charge receiving pocket, of a hopper for holding a supply of scrap tobacco, mechanism for intermittently supplying bunch charges from said hopper to said pocket, a binder cutting die and means for automatically transferring binders from said die onto said apron in position to be rolled by the apron around the charge. Preferably the above will also include means for applying paste to said binder in position to secure the binder about the charge.

These means and parts may be widely varied in construction within the scope of the claims for the particular machine selected to illustrate the invention is but one of many possible concrete embodiments of the same. The invention therefore is not to be restricted to the specific apparatus illustrated and described.

Referring to Fig. 1, the binder A cut by the die 6 is deposited by a suction binder transfer 1, such as that shown in U. S. Patent 1,543,874 to R. E. Rundell, in stretched condition and in unvarying predetermined position upon the rolling apron 8, on which it is wrapped around a measured filler charge by the rolling pin 9, thereby forming a partly shaped bunch B. The latter is delivered by the rolling apron 8, at the end of travel of the rolling pin 9, into the holders ll! of a transfer ll such as that described in U. S. Patent 1,786,609 to J. F. Halstead. The transfer II, which has a sliding as well as aswinging motion to rectify the displacement of the bunch due to the curved rolling table, places the bunch B in alignment with a pair of bunch locators I2 which are moved axially by any suitable means (not shown), towards the ends of the same to assure proper position of the bunch with respect to the mechanism to which the bunch is subsequently transferred. The details of the foregoing except as hereinafter indicated, form no part of the present invention, for which reference is made to the above identifled patents. For simplicity of illustration these parts are therefore shown for the most part only diagrammatically.

The transfer IS, the construction of which will be described hereinafter, takes the bunch from the holders l0, swings it end for end so that the head of the bunch now points in the opposite direction and inserts it into the jaws of loading carriage I4 which open to receive it, as described in the U. S. Patent 1,785,822 to G, H. Snyder.

The die 6, the binder transfer 1, the rolling pin 9, the rectifying transfer II, the bunch locators l2 and the loading transfer l3 are actuated in timed relation to each other from a shaft l5 driven by a worm l6 and worm gear I! from the 'main drive shaft [3. The shaft l5, by means of spiral gears l9 drives an auxiliary shaft 20 which in turn, by means of bevel gears 2!, drives the shaft 22 of the bunch shaping and wrapping unit. The shaft 22 has a worm 23 which, by means of a worm gear 24 turns a vertical shaft 25'on which is mounted a cam operating the carriage M. The worm 23 by means of a second worm gear 20, also drives a horizontal shaft 21 which has a cam 28 actuating a roller 29 of a cam lever 30 which, by a rod 3! and a bell crank lever 32 pivoted on a floating arm 33 swinging on turret shaft 34, imparts intermittent motion to the Geneva gear 35 driving the turret 36. Thus the drives of all parts of the combined rolling, shaping and wrapping machines are interconnected to obtain proper synchronization of all motions.

The transfer of the bunch B from the loading carriage and auxiliary shaper or compressor I4 to the turret mold is shown in Fig. 6. The carriage I4 is mounted on wheels 31 running on rails 38 and is moved back and forth on these rails by a lever 35 actuated in time by the cam on shaft 25 above referred to. As shown in Fig. 1, the bunch engaging faces of the loading carriage M are shaped to the longitudinal cross section of the turret pockets so that the bunches can be pushed therein without injury.

It will be noted that since, as presently described, the transfer fingers lfi operate on the extreme ends of the bunch the carriage compressor faces can be continuous and act substantially the full length of the bunch without need for cutting notches or cavities therein or cutting away the mid portion, to admit the transfer fingers without interference. Such notches tend to produce raised uncompressed portions which give trouble.

As shown in Fig. 7, to give compressing movement to the movable jaw Me of the compressor l4, this jaw is mounted on a lever 14b which is given a movement toward and away from the stationary portion of the compressor by means of a bell crank lever I40 and link l4d operated from the main drive of the machine by any suitable means such as a cam and cam follower, in timed relation to the operation of the rest of the machine. When in loading position above a mold pocket 40, then in horizontal receiving position, a lever 4| operated by a rod 42 actuated by the cam on shaft 25, by means of the rods 42 depresses a plunger 43 which fits into the bunch shaped interior of the carriage and forces the bunch into the mold 43. Upon the withdrawal of the plunger 43, the mold 40, by the turning of the turret, is moved into position 40' in which a stationary cam 44 mounted on turret shaft 34,

with which cam each mold is in engagement by means of a roller 45, commences to turn the mold into vertical closing position, the closure of the mold being completed at the next step of the turret in position 40", Fig. 1. The bunch B then travels in the closed mold around the turret shaft, step by step, until it reaches position 40" in which the mold begins to open, the complete opening into horizontal position being effected at the next step in position 49", in which the now shaped bunch is ejected and transferred to the wrapping mechanism, as described in U. S. Patent 1,785,822 above cited.

The transfer for conveying the bunch from the rolling unit to the compressor carriage of the shaping unit is shown in Figs. 3 to 5. A pedestal l3 mounted on the base plate 43 of the machine supports a shaft 41 which is swung back and forth through 180 degrees by a gear 48 engaging with a rack 49 actuated by a cam on the shaft I5. The rack 49 is guided by a roller 50 mounted on a stud carried by the pedestal l3. To the shaft 4'! is attached an arm 5| which carries stop screws 52 engaging at each a stud 53 in pedestal 13.

arm 5| forms a bearing for fixed a sprocket 55 end of its stroke with The free end of the a shaft 54 to which is connected by a chain 58 with a s rocket 57 loosely mounted on shaft 41, but fixed to pedestal I3. The chain 56 held taut by a coil spring 58 connecting its ends, thus imparts a half turn to shaft 54 as the arm 5| swings through 180 degrees, thereby counteracting the reversal of angular position which would otherwise result, due to the swinging of arm 5!.

For the purpose of swinging the bunch end for end during transfer, to shaft 51 is affixed a bracket 59 carrying horizontal bearings 60 and a vertical bearing 61. The bearings 60 support a shaft 62 having fixed thereto a gear 63 meshing with a gear 64 rotatable on shaft 54 and affixed to the bearing face of arm 5|. In the bearing BI is journaled a shaft 65 carrying a bevel gear 56 meshing with a bevel gear 61 on shaft 62. To the end of the shaft 65 is affixed a. holder 68 carrying the bunch gripper fingers 69 and 10.

As will be seen from Figs. 1 and 4, these grippers are in two sets, which are spaced apart laterally a distance substantially equal to the length of the bunch to grip the bunch by its extreme ends only. Preferably the grippers are spaced apart a distance equal to the length of the filler charge so that the bunch is gripped by the portion of the binder projecting beyond the end of a normal charge, thereby pinching in the binder over the end of the filler to prevent loss of scraps of tobacco and also providing access without interference for subsequent operations on the filler containing portion of the bunch.

The gripper finger 69 is stationarily attached to holder 68, While the clip I is movable, being fastened to a plate II hinged on a pin 12 in the solid portion of holder 68. Lugs '33 of plate 'H carry a pin 14 on which swings a finger 15 which on its under surface has a projection 16 which is held against a stop plate 11 by a spring 13 stretched between a post 19 in finger I and a post 80 inthe stationary portion in holder 68, this spring, when free, drawing the movable clip towards the stationary clip 69. The finger l5 and the spring 18 extend through apertures in plate H and holder 68. Through the latter aperture also presses a pin 8| attached to plate II. By

depressing the pin 8|, the clip I0 is moved away from clip 69, and when the clips are opened far enough to'receive a bunch, the projection 16 on finger snaps over the end of stop plate 11 and is held thereagainst by the spring 18 upon the release of pin Bl.

In the bunch receiving position. of the transfer, shown in dotted lines in Fig. 3, a stop 82 engages with finger 15, thereby disengaging its projection 16 from the stop plate 11 and permitting the spring 18 to close the grippers 10 upon the bunch. The ensuing swing. of arm 5| lifts the bunch out of the holders I0 and carries it to the loading carriage M, to the movable jaw Ma of which is attached a hook 83. When this jaw closes, the end of hook 83 depresses pin 8| on its return travel, to open the grippers 10.

As shown in Fig. 2, scrap filler for forming the bunch is deposited in the pocket 85 of the apron B by a suitable fully automatic scrap filler feed which takes the tobacco from a bulk supply in a hopper 86 by means of a series of buckets B1 on a chain 88 passing over sprockets B9 and SI) driven through any suitable connections such as the sprockets and chain 9|, 92, 93 (diagrammatically shown) from the main shaft l5, in timed relation to the operation of the other parts of the machine.

The scrap tobacco from the buckets is deposited on a chute 94, whence it slides into a funnel 95, having at its bottom end a. gate normally spring pressed to closed position by spring 91, and having an arm 98 which engages a stationary pin to open the gate when the funnel 91 is in its lowermost position, as shown in dotted lines in Fig. 2.

To insure ejecting of the filler charge, a plunger plate I00 is provided, secured to plunger rod Hll reciprocated by lever [02 from the cam I03. A spring I04 secured at its ends to rod IM and a sleeve H12 secured to the funnel and loosely surrounding the rod llll causes movement of the funnel with the rod until the sleeve strikes the stationary collar I05. Thus movement of the plunger rod lfll will lower the ejector plunger Illfl and the funnel 95 in unison until the sleeve H12 strikes the collar I05, whereupon the ejector plunger will move relative to the funnel and eject the charge therein.

After the filler charge has been deposited in the pocket of apron 8, the rolling pin 9 is caused to roll the bunch in the binder B, by means operated from cam I63 by lever Hi1 and link I08. For proper coaction between the die 6, the transfer and the apron 9 and to maintain the binder in stretched condition, each of these have corresponding fiat binder engaging suction surfaces. The perforated apron 8 rests in the perforated flat top of a table 8a through which air is drawn into a suction chamber 8b. To give the rolling pin 9 movement in a plane parallel to the flat surface of the table the rolling pin is provided with projecting bosses 9a at each end engaging in slots in the operating lever I06 and is guided by suitable guide rails 90 (shown broken away in Fig. 2). The upper end of the lever of course will be suitably forked or duplexed (not shown) to engage each end of pin 9 in a manner well known in the art.

The details of construction of the scrap tobacco feeding and measuring mechanism form no part of the present invention. However, for a machine showing a more refined mechanism for measuring and feeding the scrap, reference is made to the U. S. patent to Schussler 1,559,009, suitable for use in the present combination.

In the operation of the embodiment described, a measured quantity of filler tobacco is rolled into a binder, cut to shape by a suitable die served by an operator and transferred by suction binder transfer upon the rolling apron of the bunch rolling unit.

For this purpose a die is provided, having a cutting edge III of the same outline as the desired cut binder. The operator stretches a leaf on the die, the leaf is cut thereon by suitable means not shown, as rollers passing over the die, and then transferred automatically by the suction transfer head 1 to the rolling apron 8 and placed there in exact predetermined relation to the scrap filler in the pocket. This transfer head I is swung from binder receiving to delivering position by means of an arm H2 secured to a shaft H3 oscillated by a pinion l M and rack H5. The rack is reciprocated by a lever IIB having a pin and slot connection with the rack and rocked by a cam II! on the shaft l5. A flexible suction pipe connects thetransfer head I which is of perforated hollow construction, with any suitable source of suction. Since the binder is held in flat stretched conditionuntil and as it is rolled about the filler, substantially less binder material is required and the scrap is more firmly bound therein particularly at the ends where the uniform projection of the binder beyond the ends of the bunch prevents escape of scrap. As already noted, the exact location of the edges of projecting beyond the the binder resulting from the-use of a binder cutter and transfer in the present device, render it practical to apply paste to a predetermined location on the inner side and near the edge of the binder as shown in Fig. 1.

The binder paster consists of a roller I20 on an arm l2! which is oscillated by a shaft I22 from a position in which it engages a paste roll 123 to a position in which it engages the binder as shown in dotted lines in Fig. 1. The shaft I22 is oscillated by means of a pinion I24 and a rack I25 which rack is reciprocated through a pin I26 engaging in a slot I21 in a rock arm. I28 rocked by a cam l29. The paste roll is driven from the shaft 15 by drive mechanism 13c.
