16 Claims. (Cl. 164-212) This invention relates to cigar machines, more particularly to automatic feeds for web binder and Wrapper material to high speed cigar machines.

The use of such web material has increased in recent years and the need for suitable automatic mechanical feeds of such material to a cigar machine has increased.

The main object of the present invention is 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 Gladeck 2,316,784, dated April 20, 1943.

It is an object of this invention to provide the means for drawing the leading end of a web across a suction table and severing the leading end from the web while Iat the same time shaping it in a suitable form for use in a desired cigar.

It is a further object of this invention to sever a predetermined length of said severed sheet material from the leading end of a web and deliver it to the binder or wrapper transfer of a cigar machine.

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 and operated therefrom so that a portion of a web may be fed in timed relation to a binder or wrapper station of a cigar machine.

Another object of this invention is to provide in such an automatic web feeding device a cutting system that Will pre-shape a severed portion of the web and accordingly obviate the necessi-ty of die cutting.

ICC

With reference to the drawings, the tobacco sheet or web W is pulled from the roll or reel R by a pair of intermittently driven

feed rollers

20, 22. The machine 4 is started by placing the leading end of web W on a suction pickup table 24. This leading end is then picked up from table 24 by reciprocating suction feed head 26 (Fig. 9) carried across a suction table 28 (Figs. 8 and 9) and deposited thereon. Feed head 26 then returns to its original starting position.

The suction table 28 (Fig. 5) is vertically movable and is surrounded by a stationary frame 30. The table 28 has secured to it at one end a knife 36 and at its other end the

ledger plates

234 and 236 which coact with

knives

32 and 34. These knives cut a properly shaped binder on the table 28. The shaped binder is then picked up by a suitable transfer T (Fig. 1) for delivery to the rolling apron of the cigar machine (not shown). The transfer T does not form a par-t of this invention and may be of the type and construction shown in my Patent 2,287,004 dated lune 16, 1942.

The reel R (Figs. 1, 3 and 4) is supported by a shaft 38 rotatably held in suitable bearings of a frame bracket 40 fastened to the bed 42 of the cigar machine. Feed roller 20 is mounted on the shaft 44 which is also supported in suitable bearings of the bracket 40. Shaft 44 has a gear 46 which meshes with a gear 48 secured to a ysleeve 49 co-axially secured to the second feed roller 22. Sleeve 49 is rotatably supported by shaft 50 which is provided at both ends with eccentric extensions 52. Extensions 52 are supported by bearing blocks 54 slidably confined in slots 56. Both blocks 54 are arrested at the bottom of the slot by means of a vertical supporting stud 58 secured in frame bracket 40. Each bearing block 54 has a compression spring 55 confined in bracket 40 and bearing downwardly on block 54.

A lever 60 is secured to one of the extensions 52 for the purpose of lifting roller 22 upward during threading operation by rotating eccentric extensions 52. Lever 60 also has a tension spring 62 suitably anchored to the main frame bracket 40 and employed to keep lever 60 in a downward position during operation of the web feed. The web W before reaching

feed rollers

20, 22 is guided over an idler roller 64 on a shaft66 supported by a pair of arms 68 secured to a shaft 70 which is supported at both ends in suitable bearings of bracket 40. Shaft 70 carries a trip finger 72 employed for the purpose of contacting and breaking a contact in a microswitch 74 in case of a slack, breakage or exhaustion of the web W. The microswitch may be suitably wired to a warning system or to the electric drive control of the cigar machine.

Feed roller 20 is driven through its sprocket 76. by a chain 78 which is guided over an idler sprocket 80 and attached to a bracket 82 slidably supported by a horizontal rail 84 secured to the main bed 42 of the machine. Bracket 82 through a link 86 is reciprocated by an arm 88 (Figs. 1 and 2) which is pivotally secured to a suitable shaft 90 supported by the main frame of the machine (not shown). Arm 88 through an adjustable rod 92 is connected to a stud 94 adjustably secured Iin a slot 96 of an arm 98 pivotally mounted to a stud 100 (Fig. 2). Arm 98 in a bell crank fashion has a cam lever 102 carrying a cam roller 104 engaging a cam track 106 in a cam 108 mounted on a cam shaft 110 continuously driven from the main drive of the cigar machine and supported by suitable bearings in the main frame.

The hub of sprocket 76 engages with a conventional one-way ball clutch 112 (Figs. 3 and 4) employed for the purpose of changing the reciprocating movement of bracket 82 transmitted through chain 78 and sprocket 76 to one-way intermittent rotaryl motion on shaft 44.

As mentioned above, the machine is started by placing the leading end of Web W on the top surface of the pickup table 24 whose forward end is provided with holes 25 (Figs. and 9) connected to a suction chamber 27 supplied with suction by a duct 29 (Fig. 5) connected to a butterfly valve 126. The suction holds the leading end of the web on the pickup table 24. A web feed head 26, positioned above the Vforward end of the pickup table 24, is adjustably suspended from a forked bracket 114 pivotally' supported on a shaft 116. Shaft 116 is stationarily secured to a bearing bracket 118 (Fig. 3) mounted on the reciprocating bracket 82. The suction feed head 26 is of hollow construction and at its bottom surface is` provided with a plurality of communicating holes 120. Suction is applied to the hollow interior of head 26 by a communicating flexible duct or tube 122 connected to a butteriiy valve 124.

Butterfiy valves

124 and 126 are alternatively opened and closed by a shaft 128 so that in cycle suction is passed from table 24 to head 26. Both butterfly valves communicate with another suction chamber 130 connected through duct 132 to a suita'ble source of suction (not shown). Shaft 128 is operated from an arm 134 whose free end through a rod 136 is connected to a cam lever 138 (Fig. 2) pivotally secured to a shaft 140. Cam lever 138 carries a cam roller 42 engaging with cam 144 mounted on the main cam shaft 110.

The machine is timed in such a manner that after the leading edge is placed upon or has reached the suction pickup table 24 the suction is switched from pickup table 24 to the web feed head 26 so that the leading end of web W adheres to said web feed head. The web feed head 26 then advances with the leading end of web W across the entire length of suction table 28.

The web feed head is -secured to carrying bracket 114 which is loosely supported on shaft 116 and indirectly locked thereto by a spring-loaded pin 152 held by a lug 154. During the transit of web feed head 26, the carrying bracket 114, shaft 116 and roller supporting brackets 158 yand 160 are further supported by a roller 146 engaging in a horizontal track 148 integral with the top portion of a supporting member 150 secured to the bed 42.

For threading purposes bracket 114 may be raised and locked in raised position by pulling back the springloaded pin 152 lifting bracket 144 and re-engaging said pin with a second hole 156 (Fig. l) in bracket 114. Shaft 116 also loosely supports two forked

brackets

158 and 160 which carry cutting

rollers

162 and 164, respectively. Forked bracket 158 has a stop lug 166 (Fig. 3) engaging a stop screw 168 mounted on a member 170 secured to shaft 116. Member 170 further carries a pair of adjusting studs 172 surrounded by a compression spring (not shown) which engages and urges bracket 114 downward to provide a sucient pressure and resilience to the roller 162.

Forked bracket 160 which carries the second cutting roller 162 engages a lug 174 by means of a similar pair of compression springs (not shown) surrounding a pair of guide studs 176 which are held by a suitable bar 178 attached to said bracket 160. Bracket 160 furthermore is provided with a lug 180 engaging a stop screw 182 held by the member 170 to control the downward limit movement of roller 164.

During the forward movement of the feed head 26 the suction table 28 is in downwardmost position to provide sucient clearance for the feed head 26 to pull the leading edge of the web W across said suction table 28 and knife 36. The top of the suction table has a plurality of suitably spaced holes 184 communicating with a suction chamber 186 formed by the open bottom of suction table 28 and its vertical frame 30. Frame 30 is rigidly secured to a bottom plate 188 which covers a chamber 190 in a bracket 192 mounted on the cigar machine bed 42. Chamber 4 190 communicates with the chamber 130 which as mentioned heretofore is permanently connected to a suitable source of vacuum by the tube 132.

Suction chamber 186 of suction table 28 communicates with suction chamber 190 in bracket 192 through a suitable port 194 (Fig. 1). Port 194 is closed by a valve 196 when table 28 is in the downwardmost position. After feed head 26 has completed its forward motion, the suction table 28 slightly raises thus opening port 194 and permitting suction to enter the chamber 186 of suction head 28. At the same time valve 126 is closed (and valve 124 opened) to permit transfer of the web from web feed head 26 to the top of the suction table.

The suction table 28 is mounted to a vertical shaft 198 which is slidably supported in a suitable lbearing lug 200 secured to plate 118 of bracket 192. The lower end of vertical shaft 198 carries a lug 202 (Fig. 2) which has a track 204 slidably engaging a guide shoe 206. Guide shoe 206 is connected by a stud 208 to a bell crank cam arm 210 carrying a cam roller 212 which engages a cam 214 mounted on the main cam shaft 110. A tension spring 216 provides permanent engagement of cam roller 212 with cam 214. Cam arm 210 is pivotally supported by the shaft 140.

As mentioned above, the leading end of web W now lies across and is lirmly held to the suction table 28.

During the forward feed of carrying bracket 114, the feed head 26 is carried beyond the suction table 28 as shown in the dotted line position in Fig. 5. Knives 32 and 34 (Figs. 6, and 7) are secured to lugs 238 and246, respectively. Lug 238 (246) is pivotally supported by a vertical stud 240 (248) held by a suitable bracket 242 (250) secured to plate 138. A tension spring 244 (252) keeps the knife 32 (34) in contact with ledger plate 234 (236) which is secured to the suction table 28 as may be seen in Fig. 8. This mounting of the

knives

32, 34 permits them to swing outwardly as shown in dotted line position in Fig. 5 during the forwardmost transit of the feed head 26.

After the leading end of the web has been dropped to table 28 and secured thereto by suction, the carrying bracket 114 begins its return. During this return, table 28 is in a moderately raised position so that the cutting

rollers

162, 164 pass over and contact the V-shaped knife blade 36 to sever the length of material from the web W.

During this cutting operation, the suction table is verv tically locked and firmly held in place by means of a lock lever 220 which is pivoted by means of a stud 222 on bed 42. Lever 220 engages beneath a lug 224 secured to the suction table supporting shaft 198. The locking of the table 28 provides a firm support against the pressure of the cutting

roller

162 and 164, since otherwise spring 216 would yield and the table 28 drop.

As shown in Fig. 3 lock lever 220 is pivoted on stud 222 to the bed 42. A spring 226 urges it beneath a lug 224 on suction table supporting shaft 198. The locker lever 220 carries a vertical stud 228 whose upper free end engages a cam bar 230 secured to the side of sliding bracket 82. Cam bar 230 accordingly operates locking lever 220 so that locking occurs only during the cutting operation.

After feed head 26 and cutting

rollers

162, 164 have reached their backmost or starting position, the suction table 28 due to the action of cam 214 is moved further upwardly until it engages beneath a binder transfer head 232 of the binder transfer mechanism T. During this upward movement of the binder carrying suction head .28, the leading edge of the web is trimmed to the proper shape by

knives

32 and 34 cutting in conjunction with

ledger plates

234, 236, respectively.

Overrunning of the reel R is prevented by a friction band 247 anchored to a shaft 251 and carrying a weight 249 on its free end. Shaft 251 (Fig. 4) is held by a pair of lugs 253 projecting from bracket 40.

A modified embodiment of my invention is shown in Figs. and ll in which cutting of both ends of the binder is accomplished at one end of the suction head. Suction head 300 similar to suction head 28 (Figs. 1 9) has a stationary K-shaped knife 302 adjacent its first end and secured to a frame 304. Suction head 300 is vertically movable within the frame 304 secured to a plate 306 which corresponds to plate 18S above.

Shaft 310 is supported and transversely moved in the exact structure and manner as the shaft 116. Feed head 308 is supported and moved by the shaft 310. Cutting

rollers

312 and 314 are supported respectively by

brackets

330 and 332 rockably pivoted on shaft 310. Shaft 310 has stationarily secured to it lugs 334 and 336. A gear 32S is mounted on a vertical shaft 338 supported in the lug 334. Lug 334 further has two

other spindle shafts

316 and 318 threaded in it to which are secured

gears

324 and 326 which are both engaged with the gear 328. The bottom end of spindle 318 bears upon a lug 322 which projects from bracket 332 while spindle 316 engages the lug 320 secured to the bracket 330. Thus when the spindles are rotated in one direction they press downwardly on the

lugs

320 and 322 to raise the

rollers

312 and 314 and vice versa.

Vertical shaft 338 to which gear 323 is mounted carries an actuating nger 340. A set screw 342 in a lug 346 fastened to plate 306 is positioned to engage actuating finger 340 during the last portion of the return stroke of the shaft 310 and a similar stop screw 344 in a lug 348 secured to the plate 306 engages the actuating linger 340 during the last portion of the forward stroke of the shaft 310.

In operation, when the cutting rollers are at their starting position they will be in a raised position and will remain in this position until the end of the forward movement Vof the feed head 308. Toward the end of this forward movement the actuating nger 340 will strike the set screw 344, rotate the shaft 338 and gear 328 which in turn will rotate

gears

324 and 326 and their

spindles

316 and 318 to lower the cutting rollers. Upon the return movement the rollers contact the K-shaped knife 302 thereby cutting the binder web. K-shaped knife 302 severs the leading portion from the web, shapes the following edge of said leading portion and at the same time cuts the desired shape of the leading end of the next portion which will be severed on the next cycle. The operation of suction table 300 and feed head 308 is identical with the operation of table 28 and feed head 26.
