national Cigar Machinery Company, New Jersey assignor to Intera corporation of This invention relates to cigar machines, more particularly to automatic binder and wrapper material feeds for high speed cigar machines.

In cigar machines heretofore used, a tobacco leaf was spread on a cutting bed provided with a die of the required configuration to cut a wrapper or bunch binder. In such machines, the output depends upon the experience and speed of the attendant in placing the tobacco leaf on the cutting bed.

It is the main object of the present invention to automatically feed the wrapper and/or binder material in the form of a continuous web of tobacco sheet material, for example of the type taught in the patent to Wells et al. 2,433,877 dated January 6, 1948.

his the object of this invention to provide a means for feeding such a sheet across the bunch rolhng table or to the wrapper applying mechanism of a cigar machine.

It is a further object of this invention to sever a predetermined length of said sheet material during the feed thereof.

A further object of this invention is to devise a mechanism that may be readily and automatically timed with the operation of a cigar machine, whereby said material will be fed commensurate with the speed of the cigar machine and will be independent of the ability and skills of an operator. v In-the accompanying drawings:

Fig. 10 is a sectional plan view, taken on line 1010 of Fig. 9, illustrating the cutting knife release mechanism.

With reference to the binder material feed mechanism illustrated in Figs. 1, 2, 3 and 4, this device consists of a frame bracket secured to the table 22 of a cigar machine. The upper portion of bracket 20 loosely supports a hollow shaft 24 the ends of which are closed by means of suitable plugs 26 to form a chamber 82. H01- z low shaft 24 is rocked by means of an arm 28 secured thereon. The free end of arm 28 is provided with a slot 38 (Fig. 1) to engage a suitable clamp screw 32 to Which is pivoted the upper end of a connecting rod 34 whose lower end is pivoted to the free end of a cam lever 36 loosely supported on a shaft 38 of the cigar machine (not shown). Cam lever 36 carries a cam roller 40 (Fig. 1) which engages with a cam 42 keyed to the main cam shaft 44 of the cigar machine. Shaft 44 also has another cam 46 engaged by a cam roller 48 on a cam leve 50 loosely supported by a suitablestud 52. v

An arm 54 extends from the hub of lever 50 and is connected at its free end by an adjustable rod 56 to a slide valve 58 protruding into a valve housing 60 which is connected by a tube 62 to a source of suction (not shown). Valve housing 60 is also provided with two

ports

64 and 66 and the slide valve 58 is provided with an opening or hole 68. Port 64 through tube 70 is connected to the suction chamber 72 of the rolling table 74. The top surface of table 74 is provided with perforations or holes 76 (Fig. l) which match up with the holes 77in the rolling apron 78. The structure and operation of the rolling table and apron are well known in the art and therefore further description is not deemed necessary. Port 66 of valve housing 60 is connected by a tube 80 to chamber 82 in hollow shaft 24.

When the cam roller 48 on lever 50 contacts the lowest portion 84 of cam 46 the slide valve 58 is moved to a position where its opening 68 coincides with port 66' of housing 60 to apply suction to chamber 82 of hollow shaft 24, the function. of which will be described later on.

When the cam roller 48 of lever 50 contacts the highest portion 86 of cam 46, the opening 68 of slide valve 58 opens port 64 to apply suction to chamber 72 of rolling table 74 and consequently through holes 76 in its top surface and holes 77 in rolling apron 78. Thiscauses a binder laid thereon to adhere.

When the cam roller 48 of lever 50 contacts the intermediate portion 88 of cam 46 opening 68 of the slide valve 58 is positioned between

ports

64 and 66 and no within the hub 92 communicates with chamber 82 of the hollow shaft 24 while its bottom end carries and communicates with a hollow suction head 96 provided with a perforated binder pick-up plate 98. Thus,

suction is applied to pick up plate 98 of feed arm when slide valve 58 permits suction to enter the tube 80 via port 66 of suction housing 61).

A pair of integral lugs 180' project from one end of head 96 and carry at their ends a horizontal shaft 102'.

A pair of spaced levers 184 are secured to shaft 102.

, One of these levers has an extension 106 supporting a roller108 engaging with a guide track 110 which by means of a pivot 112 and a thumb screw 114 is adjustably held by and attached to the frame bracket 20.

Hollow shaft 24 also carries a gear 118 provided at its hub 120 witha conventional one-way ball or roller clutch 122 so that as the shaft 24 is oscillated' by means of arm 28, gear 118 is driven intermittently in one direction only. To prevent blacklash during this operation a spring loaded pawl 124 engages the teeth of said gear 118'. Pawl 124 is pivotally supported by a stud'126 held by a suitable lug 128 extending from bracket20. Gear 118 through a pair of intermediate gears 136) drives a gear 132 and its shaft 134 to which 'is secured a drum or roller .136. ,Shaft 134 as well as stud shaft 138 to which intermediate gears are lc i Patented June 3, 1958'" pivoted are supported by a bearing arm 140 which in stud shaft 142 held by a suitable lug 144 projecting from frame bracket 20.

The binder material feed described above and illustrated in Figs. 1, 2, 3 and 4 operates as follows:

A length of web W is first pulled off the reel R and placed onto an inclined and stationary bridge plate 146 supported by a lug 148 projecting from frame bracket 20. Web W is laid on said bridge plate so that its leading edge is even with the front edge of binder pickup plate 98 of suction head96. Assume that, at this moment, the cam roller 48 of cum lever 58 is in contact with the low portion 84 of cam 42 causing slide valve 58 to stand in a position which permits suction to enter tube 88 and consequently act through perforated binder pickup plate )8 to pick up the leading portion of the binder web W. Upon rotation of cam shaft 44 in the direction of the arrow in Fig. 1, the binder material feed arm 90 due to cam 42 and the therewith connected parts moves forward in the direction of the arrow F, pulling web material from reel R. Roller 136 in contact with the periphery of reel R is positively driven during the forward motion of feed arm 98 and therefore assists in the feeding of web W. As arm 98 reaches a vertical position as indicated in dotted lines (Fig. 1) above the forward end of the rolling table, the suction, due to action of slide valve '58 is cut from feed arm 90 and switched to apron 78 on rolling table 74 causing the leading portion of web W to disengage from pickup plate 98 of arm 90 and adhere to rolling apron 78.

Arm 90 then returns to its original starting position where knife 116, operated by arms 104 and guide track 110, engage the ground forward edge 99 of pick up plate 98 to cut off that portion of the web now lying on apron 78. During the backward motion of arm 90, of course, no feeding action took place, since the web was not in contact with the pick up plate 98 and the reel R was not turned by roller 136 due to the disengagement of one-way ball clutch .122 as shaft 24 was rocked clockwise with reference to Fig. 1.

Ann 90 is operated from cam 42 which is in time with the cigar machine so that a bunch charge is placed on the binder as it is delivered to the apron so it may be rolled in the manner well known in the art. The cut piece of binder web is placed on the rolling apron at an angle to achieve a somewhat spiral wrapping during the rolling operation.

A modified embodiment of my binder material feed is shown in Figs. 5, 6, 7, 8, 9 and 10. It also consists of a frame bracket 150 which is secured to the bed 22.

of a cigar machine and which in its upper portion loosely supports a shaft 154 rocked by means of an arm 156 mounted thereon. Arm 156 is provided with a slot 158 engaged by a clamp stud 160 of the upper end of a connecting rod 162. The lower end of rod 162 is pivoted on a stud 164 to a cam lever 166 rotatably supported on a transverse shaft 168. Cam lever166 carries a cam roller 170 engaging a cam 172 mounted on the main cam shaft (not shown) of the machine. Cam 172 effects a raising and lowering of arm 156 which in turn causes shaft 154 to rock.

The binder material feed arm 174 is secured to rock shaft 154 and consists of an arm member 176 which on its lower free end carries a pair of feed rollers 178 one of which may be of rubber, if desired. Each roller 178 is mounted on a shaft 180 to each of which is also secured a gear 182. Both gears 182 mesh with each other and both shafts 180 are supported in suitable bearings in the fork-shaped free lower end of arm member 176. The upper of the two gears 182 also meshes with another gear 184 connected to a shaft 186 by means of a conventional one-way ball or roller clutch 188. A pawl 198 pivoted to arm member 176 by a stud 192 engages the teeth of gear 184 and in conjunction with ball clutch 188 permits rotation of gear 184 in one direction only. Shaft 186 to which gear 184 is connected is oscillated by means of a gear 194 mounted thereon and engaging an arcuate stationary gear segment 196 loosely supported by the oscillating shaft 154 and secured to the frame bracket 150 by means of a screw 198 (Figs. 5 and 6).

The lower portion of arm member 176 also carries a web cutting mechanism consisting of a vertical rod 280 having a V-shaped cutting blade 282 secured to its lower free end. Blade 282 is also slidably secured to the forked free end of arm member 176 by a pair of studs 284 engaged in the vertical slots 206 of said blade 282. A compression spring 288 surrounding each stud 204 urges cutting blade 202 against a ledger block 210 to assure a clean cut. Ledger block 210 with a guide lug 212 forms a guide channel 214 to support I the leading edge of the binder material web W. Ledger block 218 as well as guide lug 212 are suitably secured to the forked end of arm member 176.

The vertical rod 280 is slidably supported in suitably spaced ribs of arm member 176 and is provided with a collar 216 which is urged against the top surface of the lowest rib 218 by means of a compression spring 220 surrounding rod 200 and confined between said collar 216 and the under surface of a rib 222 located above rib 218. A latch finger 224 is pivotally mounted by a vertical stud 226 to the top surface of rib 218 adjacent collar 126. One end portion of latch finger 224 is urged against the side of collar 216 by a tension spring 228 held on a stud 230 and anchored to the top surface of rib 218. The other end of latch finger 224 contacts the end of an adjustable trip screw 232 (Fig. 10) which urges and keeps the opposite end of said finger 224 away from the collar 216 when the arm member 176 is in its backmost or starting position. The trip screw 232 is held in a stud 234 secured to a lug 236 projecting from the end of stationary gear segment 196. Vertical rod 280 is raised by lifter cam 240 on oscillating shaft 186 engaging lifter block 238 on rod 208. i

The binder material in reel R is wound between a pair of flanges 242 supported by a stud 244 on an arm 246 of frame bracket 150.

The auxiliary driving means shown in Fig. 1 and having the drum or roller 136 may also be used for applying driving power to the roller 242 of Fig. 5.

It is the object of this material feeding device to pull a predetermined length of web from said reel over bunch rolling table 258 and then cut therefrom a binder which then due to suction adheres to the rolling apron 252 on the rolling table 250. The latter is of the same type and design as the one illustrated in Fig. 1, the formation of which is well known and universally used in the art. Said bunch rolling table is provided with a chamber 254 which, by means of a tube 256, is connected with a suitable source of suction (not shown). The top wall 258 of said chamber is provided with suitable holes 260 which match up with suitable holes or perforations 262 in the rolling apron 252 attached to the front end of said rolling table.

The modified binder material feed and web cutting mechanism illustrated in Figs. 5, 6, 7, 8, 9 and 18 operates as follows:

We assume that a web W is pulled off the reel R the leading, portion is threaded between the rollers to the knife or cutter blade 202 which with the arm 176 in backmost or starting position is in its lowermost position blocking the guide slot or channel 214. As arm member 1'76 due to the act-ion of. cam 172 upon arm 156 moves forward the gear 194 carried by said arm memand br and meshing with stationary gear segment 196 starts to rotate and with it the shaft 186. This rotation of shaft 186 causes a turning of the rod lifter cam 240 mounted thereon to lift through block 238 vertical rod 200 bearing cutter blade 202. As collar 216 rises, the end of latch finger 224 is moved beneath collar 216 by spring 228 since the other end of latch 226 is free of screw 232. The cutter blade is thus held up and slot 214 is open. Although the shaft 186 is turned by gear 194 due to the forward motion of arm member 176, yet gear 184 engaged by pawl 190 does not turn because of oneway ball clutch 138. Accordingly, rollers 1'78 remain stationary with the leading end web W clamped between them, thus pulling a predetermined length of said web above and over apron 252 on rolling table 250.

After reaching its forwardmost position as indicated in dotted lines in Fig. 5, the arm member starts its return through action of cam 172. During this return, gear 194 and shaft 186 rotate in the opposite direction and one-way ball clutch 188 in gear 184 engages shaft 186, rotating rollers 180. The turning of rollers 180 during the return stroke of arm member 176 does not cause any pulling on the web and the rollers simply run over the pulled out length of web. This permits it to drop on rolling apron 252 to which it adheres by suction. As arm member 176 completes its return stroke, the free end of latch finger 224 is contacted by trip screw 232 releasing collar 216, rod 200 and cutting plate 202. This causes a cutting action against ledger plate 210 severing the length of web pulled out during the forward motion of the arm member 176. The balance of the cut binder is immediately sucked down on rolling apron 252. The

newly cut leading end of the web leading from the reel, of course, is held in the grip of the two rollers 178 so a new length of web may be pulled from the reel in the next cycle movement of arm member 76.

In a device such as claimed in claim 20, further characterized by a lever secured to the pivot of said free arm, a cam mounted on the main cam shaft of said cigar machine, and a cam follower'operatively secured to said lever and engaging said cam to move said arm to and fro across said station in timed relation to said cigar machine.

22. In a cigar machine having a bunch rolling table, the combination with an arm pivotally mounted at its one end to swing its free end to and fro across said table, of gripping rollers mounted at the free end of said arm, of drive means to rotate said gripping rollers in one direction only during the one swing of said arm, severing means operatively mounted adjacent said gripping rollers to sever a web held therebetween, and control means operated by said cigar machine to move said arm to and fro in timed relation to said cigar machine and to operate said severing means at a predetermined time toward the end of said one stroke whereby a web of sheeted tobacco material may be drawn across said table during the other stroke of said arm and fed thereon by said rotating rollers during the one stroke and then severed for deposition thereon.

23. An apparatus for feeding a predetermined portion from a continuous source of tobacco web material to a station, an arm pivotally mounted to swing from said continuous source of web material to and fro across said station, cooperating gripping rollers on the free swinging end of said arm, engaging gears secured to the ends of said gripping rollers whereby they may be totated, a drive gear engaging one of said engaging gears, a shaft whereon said drive gear is mounted, a one-way clutch to drive said shaft in one direction only a gear to drive said clutch, a stationary gear segment mounted in the arc of said swinging arm engaging said last-named gear to rotate it backwards and forwards during the swing of said arm whereby said gripping rollers are stationary during one swing of said arm and are rotated during the other swing of said arm so that a web of continuous sheeted material held between said rollers is pulled forward during the one swing of said arm and said arm will move backward without disturbing the position of said web due to the rotative motion of said rollers.

24. In a cigar machine having a bunch rolling table, a roll of tobacco web material mounted adjacent said table, grippers to grip the leading edge of said web, mechanism to move said grippers forward and return across said table with said web gripped thereby during the forward movement to draw a portion of said web across said table, said mechanism having a driven roller engaging the periphery of said roll of web material, said driven roller having a peripheral speed substantially equal to the speed of said moving grippers during their forward movement so that said driven roller by engaging the periphery of said roll of said web material will feed web material at substantially the same speed as the speed of said moving grippers, said grippers comprising gripping rollers to support therebetween the leading end of a sheet of web material from said source, and other means to rotate said rollers during the return swing of said arm so as not to disturb the position of the web pulled across said table by said grippers during their preceding forward movement.
