15 Claims. (Cl. 13121) This invention relates to long filler cigar machines, and particularly the feeding of long filler tobacco and the formation of long filler cigar bunches.

One of the principal objects is to form an improved filler bunch charge of long filler tobacco suitable for rolling into a Spanish bunch. Heretofore, it has been necessary in forming such bunch charges to make a horizontal cut parallel with the laminae of the bunch charge. Since, from the nature of tobacco leaf, these laminae are not perfectly even and in a single plane, the line of cut tends to mutilate the several laminae through which it passes. One method of overcoming this objection, as disclosed in the copending application of Neumair and Clausen, S. N. 147,178, filed March 2, 1950, is to form a bunch charge by severing charge lengths at the forward end of a thin stream of tobacco and compacting these charges sidewise to form a second thin stream (of bunch length width) and then severing charge bunch widths from the forward end of this second stream. This method has proved of great advantage.

It is, however, an object of this invention to improve the method of sidewise compaction by positioning thin charge bunch lengths side by side in overlapping or shingled relation. This shingling facilitates the compaction and produces a better interlacing of the laminae of each charge length to form a more continuous and homogenous stream. In streams formed from sidewise compaction of charge lengths, the laminae frequently fail to interlace. This produces bunch charges known as splits and is composed of two longitudinal sections each representing a portion of an original charge length. Cigars formed from such bunch charges have a tendency to burn unevenly, since the split forms with the binder and wrapper a veritable flue along the side of the cigar.

Still another object of the invention is to shingle successive charge lengths upon the preceding charge length in a predetermined overlap. Since the charge lengths are cut on corrugated cutters, it is advantageous to locate this overlap so that the corrugation of the one charge length coincides with the corrugation of the prior charge length.

It is a further object of my invention to design a mechanical apparatus that will accomplish my method in a satisfactory manner that will not only form a thin stream of charge lengths but will form it in a shingled fashion with controlled overlap.

It is a further object of my invention to provide a means of varying the predetermined width of a charge bunch automatically in accordance with its thickness. Thus, if a charge bunch of greater than average thickness is formed in the sidewise compaction stream, the width of said bunch will be compensatingly slightly less than average and, conversely, if a thinner than average bunch is formed, the final width severed will be slightly greater than average.

My invention is designed to incorporate all the advantages of the aforementioned co-pending application plus the above-mentioned improvements. Other objects r ce will be apparent from an understanding of the following specifications.

Fig. 8 is a diagrammatic sectional side elevation of a portion of the horizontal bunch charge column illustrating the whole leaf width sections in a bunch charge.

Referring to Figs. 1, 2 and 4, whole leaves of long filler tobacco T are fed on a wide cross-feed belt 2. It should be pointed out that this cross-feed differs from conventional cross-feeds commonly employed today in cigar machines in that it has no vertical side channel belts but only the bottom belt 2. This is because the channel is constructed wider than the width of the tobacco leaves employed. This permits placing the leaves on the belt to form a thin stream, thick in the center and tapered toward the edges. The sides of the channel may be formed by stationary members 4 as illustrated in Fig. 1.

Tobacco T is fed forward onto transfer platform 10 the distance of a bunch length, whereupon the corrugated cutter 6 is, by means not shown, moved downwardly to cooperate with the stationary and complementary cutter 7, to sever a charge length. The charge length L is stripped from the cutter 7 by the fingers 12 which drop into clamping position as cam piece 66 disengages the stud 82 on the lever 81. Lever 81 is secured to shaft 83 to which are secured the fingers 12. Cam piece 66 is operated by means not shown in conjunction with the operation of the cutter 6. This may be done in the manner disclosed at Fig. 6 of the copending application of Neumair and Clausen, S. N. 147,178.

The operation and mounting of the platform is as follows: I

Shaft 16 rotatably mounted in the frame of the cigar machine (not shown) has rigidly attached thereto a cam lever 18 carrying at its free end a cam roller 20 which bears on the cam 21 secured to rotating shaft 15. Also secured to the shaft 16 is the lever 22 to whose free end is pinned a supporting link 24 by means of pin 25. Cam lever 18 and lever 22 through shaft 16 operate as a bell crank lever. Tension spring 23 keeps the cam roller 20 in contact with the surface of the cam 21.

Link 24 by means of pin 27 loosely engages a slot 26 of vertical support 28 to whose upper end is rigidly secured platform 10. To maintain the support 28 in the vertical position, a link 30 runs from the bottom of the support 28 to a pin 31 on the free end of a link 32 pivoted at its other end to a stud 34. The links 24 and 30 cross each other and are commonly pivoted at their point of intersection to one end of link 36 by the pin 35. The other end of link 36 is attached to the free end of cam lever 38 pivotally secured to stud 40. Cam lever 38 has a cam roller 42 which is held in contact with cam 44' by the tension spring 46. This parallel linkage maintains the platform 10 in a horizontal position while permitting both vertical and horizontal movement thereof.

Horizontal movement of the platform 10 is initiated tioned Neumair and Clausen application.

by movement of the lever 38 as the spring 46 causes it to execute the motion defined by the cam'44. As the lever 38 moves to the right the platform 1% will likewise move to the right due to the toggle action of the links 24 and 30 on the vertical support 28. As the pin 35 moves between the pins 31 and 25, pin 27 rides freely in slot 26. a

Vertical motion of the platform results from the motion of lever 18. Cam roller 26 in lever 18 is held in contact with the cam 21 under the tension of the spring 23. As the lever 18 swings counter-clockwise the shaft 16 and lever 22 likewise are rotated counterclockwise. This counter-clockwise motion is transmitted to the links 36 and 32 as may be clearly seen in Fig. 1. The pins 25, 35 and 31 accordingly move in a downward are and with them the vertical support 28 and the connecting links 24 and 39.

The shingled horizontal columns of tobacco is fed forward on a belt 50 supported on a plurality of idler rollers 52 and driven by drive pulley54. The upper or active run of the belt is further supported by the table 56. The belt feeds forward the shingled tobacco compacted beneath the lower horizontal run of the belt 58 whose drive pulley 6t! is connected to the drive pulley 54 through hub gears 62 and 64. The idler pulley 67 of the compressor'fbelt -58'is supported on one end of a lever 68 pivoted on fulcrum shaft 79. The other end of lever 68 supports the link 72 to which is attached wedge-shaped member 74. As tobacco is fed forward on the belt 50 it is compacted beneath the belt 58 in the channel 57 formed between belt 58 and belt 50 and against the fingers 196 whose structure'and operation 7 is the same as the finger plate 196 of the above-men- As the tobacco attains a predetermined compaction pressure against this finger the motion of the drive pulley 54 is arrested by means illustrated in Fig. 7.

Referring to Fig. 7, the fingers or finger plate 196 are secured to .a member 252 pivotally secured on an arm 254 loosely mounted on'a shaft 256 held in the frame of the'machine. The opposite end of this arm 254 carries a cam roller 258 engaging a cam track 260 of a cam 262. This arm 254 raises and lowers the fingers 196 into and out of operative position in the slot 188, in the same manner as the arm 254 of the aforementioned Neumair and Clausen application.

Also pivotally attached to the member 252 is one end of the arm 250 composed of two sections 249 and The other end of the-arm 250 is pivoted to the free end of lever 242. Lever 242 is secured on shaft 224. Also secured to shaft 224, is counterweight lever 238 with its adjustable counterweight 240.

As the belt 50 moves the tobacco forward and it is compacted against the finger 196, the finger yields raising the weight 238 through the above described linkage 250, 242 and the shaft 224 is rocked clockwise.

Loosely mounted on shaft 224 is the latch 214. This latch is held by spring 216 against a pin 218 mounted on a lug 220 secured to a sleeve 222. The sleeve 222 moves with the lever 238 by means of its attachment thereto by the pin230 mounted on a lug 228 also secured to the sleeve 222.

'The clockwise movement, therefore, of shaft 224 moves latch214 out of engagement with a pawl 208 which then under the influence of spring 209 engages ratchet wheel 210. This causes a clutch 18!) to disengage shaft '15 from gear 211 driving gear 53. Gear 53 is secured to shaft 55 whereby pulley 54 (also secured to shaft 55) is driven. The feed stroke of belt 56 is thereby terminated.

The next feed stroke is begun when the high spot of a cam 1-98 on shaft 15 contacts a cam roller 200 on an arm 292 to which is secured a pin 206 which contacts the free end of pawl 208. Thisraises the pawl 4 I out of engagement with ratchet 21f), thereby i e-engaging clutch 180.

An arm 246 pivoted on stud 248 engages section 249 of arm 250 by means of a pin 93 and a slot 95. This arm 246 carries a cam roller'2 66 engaging 'a'carn surface 264. As thefingers 196 are urged forward by the tobacco, arm 246 moves forward, riding away from the cam surface 264. After the latch 214 is tripped free of the pawl 208, cam surface 264 overtakes cam roller 266 and moves the fingers 196 further forward so that it clears the tobacco during its descent with the arm 254. Cam surface 264 then gently returns the fingers 196 to their starting point in time for thenext cycle.

The link 250 is composed of two parts 249 and 251, which overlap each other a distance established by the wedge-shaped member 74. The operation of this structure depends on the thickness of the tobacco beneath the compression belt 58. In the event that overly thick charge lengths are fed to platform 10, the pulley 67 is raised during the passage of such lengths along belt 59. The descending link 72 is lowered, causing the wedge member 74 to increase the overlap of the members 249 and 251, thereby shortening the length of the tacts finger 196 sooner, and sooner raises weight 240' by the above described linkage 256, 242 and shaft 224. 7

By raising weight 240 slightly earlier in the cycle, latch 214 releases pawl 208 sooner and the'clutch 180 disengages shaft 15 and pulley 54' is no longer driven by the mesne linkage already described. Thus the length fed is less. In the event of an overly thin charge length there is a relatively contrary action to lengthen the feed stroke of pulley 54. That is, finger 196 is contacted later in the cycle and the feed is correspondingly longer.

A cam 73 is mounted on one end of a shaft 76 to the other end of which is secured a gear 84. The gear 84 meshes with gear which rotates with the shaft 55 of pulley 54. This cam rotates approximately once for each increment of the belt 50. A cam follower 86 is mounted in an arm 48 pivoted on a stud 77. The free end of arm 48 is provided with a slot 9f; which engages the pin 91 connecting arms 36 38. As arm 38 and its other connecting links are urged forward un- V der the influence of spring 46, cam follower 86 contacts cam 78 and the forward motion of platform ii) is arrested. Thus, the position of the cam .73 determines the prior feed stroke of the pulley 54.

M ode of operation In operation, the tobacco T, composed of a thin stream of tobacco leaves, is placed on the belt 2. Bunch length charges are fed to the platform 10 and severed by corrugated cutter 6. The finger rods 12 descend to grip the bunch length L on the platform 10. Platform 1% then is lowered and advanced to dotted line position shown in V Fig. 1. This position varies according to rotation of the cam 78 which, by the linkages associated therewith, defines the length of the prior feed stroke of the belt 59. The claw 88, supported on vertical shaft 92, is then lowered by the shaft 92 through the action of cam lever 94 and cam 96. This claw 88 holds the-tobacco during the withdrawal of platform 10-.

Because of the controlled horizontal advanceiof the platform 10 relative to the feedbelt 50 the corrugations of the tobacco charge length L will register with the corrugations of the prior charge length LP when deposited thereon in overlapping fashion to form shingled stream S.

When tobacco is compacted against the finger plate 196, clamp plate 272 in cooperation with claw 322 (more fully described in the above mentioned Neumair and Clausen specification) rips off a measured hunch charge of a predetermined weight and density. Because of the overlapping of the various bunch lengths the final bunch charge will contain some laminae extending substantially throughout the entire Width of the bunch charge. That is, by overlapping, the laminae are not longitudinally wrinkled or corrugated during the sidewise compaction. Since the width of a leaf may be as wide or wider than a bunch charge, it is inevitable and inherent in my method that some leaves will provide a lamina substantially of bunch charge width in each bunch as note the bunch charge width to the right of plate 272 in Figs. 1 and 5. In viewing the illustration, it should be borne in mind that each lamina is slightly angled from the horizontal by the shingling. In Fig. 1 compare the position of the leaves in tobacco T with the leaves in stream S. It will also be more uniform in density because the shingling of the charge lengths permits a smoother and better compaction.

Figs. 6 and 8 illustrate the structure and conformation of the horizontal bunch charge column S. Fig. 8 particularly shows how leaf portions will be positioned in the final charge W. It is obvious that the tobacco charge length L is composed of whole leaf width portions due to its severance from the leading end of the tobacco T on the belt 2 and also due to the width of the stream T. When the tobacco charge length L is overlapped as at V on the prior charge length LP, any severance of the stream S thereby formed on belt 50 requires that there be some whole leaf widths present. It further follows that certain of the whole leaf Widths will extend throughout the width of the final bunch charge (leaf 1' for example). This becomes more apparent by reference to Fig. 6 where it may be seen that some whole leaf width portions are wider than one-half the width of charge length L. For, as may be seen in Figs. 5, 6 and 8, the overlap is approximately one-half the width of charge length L. Consequently, the final bunch charge has two very favorable characteristics (1) it contains whole leaf widths l and (2) some of its whole leaf portions 1 will extend the full width of the final bunch charge.
