20 Claims.

This invention relates to cigar machines, and more particularly to a method of feeding long ller tobacco and an improved and simplified filler feeding mechanism therefor.

Usually when feeding long ller tobacco into charge forming mechanism, the operator places the leaves in a feed channel and forms therein by constant addition thereto a continuous stream of long filler tobacco which is advanced past cutters which sever bunch length sections therefrom; these sections are then passed on to other tobacco handling instrumentalities and suitable bunch charges are made and transferred to bunch rolling mechanism. In feeding tobacco in `this manner the operator must endeavor to keep the tobacco in the stream up to a certain level, and not feed to much or too little lest the resulting bunch charges reect these variations and be overheavy or underweight.

According to the present invention, an operator feeds tobacco in usual manner to form a continuous stream, but it is relatively unimportant if she overfeeds. In fact she may overfeed without any danger of the resulting bunches being overheavy since automatically acting mechanism is provided for limiting the stream passing to the bunch length cutters to uniform thickness and density. From this it follows that operators feeding tobacco in this machine need not be highly skilled in order to feed long ller tobacco satisfactorily. Also, `due to the fact that the machine of this invention forms bunch charges of long filler tobacco of uniform size, thickness and density in a simplified manner, and cuts the tobacco only once, the possibility of forming undesired scrap, which is often produced when several cuts are needed to form a bunch charge, is heldto a minimum, and hence better bunches and more satisfactory long filler cigars result. Furthermore, the formation of measured bunch charges in the feed mechanism of the cigar machine results in a simpler machine, and eliminates many machine parts heretofore necessary toproduce bunch charges.

It is an object of this invention therefore to provide a method of feeding and a long ller tobacco feed mechanism for a cigar machine in which cigar bunch charges of substantially uniform size and density are produced with a minimum of cutting.

It is a further object to provide a method of feeding and a feeding mechanism having devices for forwarding a continuous stream of long filler tobacco, and means for automatically reducing the stream to uniform thickness and density as it travels to the cigar bunch length forming mechanism. Y

The invention also consists in the provision of automatically acting means for advancing a continuous stream of tobacco past compressing and trimming devices which compact the stream to a substantially uniform density, remove the excess from the stream and automatically redirect it back for association with later fed tobacco.

The invention also contemplates the provision of bunch forming mechanism of a simplified nature in which the skill of the operator feeding leaves to the advancing means has relatively little effect upon the finished cigar, especially insofar as overfeeding is concerned,

In the feeding of tobacco in this machine the stream of tobacco has been reduced to the predetermined size, thickness and density before it is fed to the bunch length cutter, and the resulting bunch lengths are each ejected onto the rolling apron for formation into bunches. It is evident, therefore, that no accumulating errors of size or density can creep into the bunch length due to the association of several lengths which may be of varying Weight and density, and the severance of a bunch charge from the leading end of the assembly. The invention, therefore, includes -means for forming uniform bunch charges from an advancing stream of tobacco by a single severing operation, and the formation of bunches from successive individual charges transferred from said means to the rolling mechanisrn.

In addition to the mechanism which has been provided for automatically removing excess tobacco from the top of the stream and returning it to the source for further feeding, there is also contemplated means for signalling when insufficient tobacco is being fed in order to notify the operator so that she may bring the quantity to be fed up to the requisite amount before a number of bunch charge increments have been fed through the feed mechanism to do much harm in the production of non-uniform bunches.

With these and other objects not specifically mentioned, in view, the invention consists of certain constructions and combinations which Will be hereinafter fully described, and then set forth more specifically in the claims.

VThe filler tobacco is placed into the filler feeding channel formed by the horizontal feedA belt I and the two vertical feed belts l l and l2, this channel forming the feed for ller tobacco similar ,to that shown in the patent to Bronander, 1,740,571, granted December 24, 1929. The horizontal belt Ill is supported upon a plate iS of a width substantially that of the belt, and may be driven in the same manner as disclosed in the above patent. The Vertical belts Il and i2 are supported in tobacco engaging position by pulleys I3 and I4, and pulleys I5 and i6, respectively. The belts II and I2 are also led around suitable guide rollers HIJ of Well-known design and arrangement suitably mounted on the machine table B and-the belts are formed into tightening loops about these last-named rollers. The belts, mentionedabove Which form the feeding channel, are intermittently driven by suitable means such as disclosed in the above-mentioned patent to Bronander. l

In a device such as shown by Bronander, bunch lengths cut from the advancing stream are not complete and ready for rolling with binders into bunches. Instead, lengths are pushed laterally into'juxtaposition with previously cut lengths, compacted to proper density, and charges are cutfrom the leading edge of the grouped lengths. This cutting naturally results in the formation of 'some scrap'particles, which are unwanted in long ller cigars. According to the structure shownin Figs. 1, 2 and 3 all of the operations necessary to produceibunch charges of Vproper size,"thic'kness and density are effected in the feed `mechanism; the bunch charge is out only once-thereby practicallyV eliminating the formation of small pieces and the-mechanism employed is simpler byv many parts.

The filler tobacco progressively 'placed in the iiller feed .channelformed bythe belts I0, I-I and I2, is intermittently advanced Aand passes Ain a v stream of -varying thickness and density under a guide Allocated vto directit beneath compactor I8,1.which in theillustrated embodiment consists of a wheelV lamounted upon a shaft I9. .Asprocket .29 `fixed on `the end of .shaft I9 .is suitably driven, by a conventional chain. drive not shown, from thedriving means of pulley I5.

.The compactor wheel I8 is .provided with a series of `spaced-radial holes .2I, Fig. 2, each of which receivesa shank 22 of the several plungers or compactors 23.v The `shank 22 of each plunger supports a stud 24, equipped with a cam follower 25 adapted to engage the inner periphery of an adjustable stationary cam 26. This cam s mounted on bracket 26e, which is provided with a semicircular extension 26a upon which the cam 26 may be moved circumferentially in order to position the lowermost portion 26h of `the cam in the proper location for best results. Adjustments are effected` by means of openings vand screws respectively formed in and carried by the cam and semicircular brackf et extension 26a. While several means may be cam'followers move oii the high part 0f the cam 26,v springs 2l will force the Compactors into contact with the advancing stream of tobacco and compress it to the predetermined density. Itis-obvious that weights or other cam controls Vcould be utilized for this same purpose. it is apparent that there can be no positive crushing force applied to break up the tobacco and at the samegtime the density of the layer treated by the compacting device will be substantially uniform because ofthe operation of Compactors 23 and .the settingof the wheel I8. Variations in density of the layer vpassing to the bunch charge severing cutter are extremely unlikely. Each compacter 23 is Vcontinuously pressed by its respective lspring 21 outward against the tobacco stream, which stream is thereby'brought to proper density and soheld. The Compactors 23 d onot recede or rise until theirlcontrol cam followers 25 ride up on cam 25 again following the cutting operation ofvknife 30.

In order to change -the compressive'force of the compactors23 and Vvary the density of the stream, shaft ,9 4is vertically adjustably mounted inbracket 26e which is suitably fixed to the bed B. This shaft is journaled for rotation in an adjustable .block 26e slidable inslot 26d of bracket-26o. The required'adjustments are made by `turning screw 2(5)c right or left to raise or lower block Ze. VLocknut 26g holds the screw 26f in 'adjusted position.

In order to form alayer of tobacco of proper thickness a knife 3i) is mounted in the path of the filler tobacco stream usually with vits cutting edgefbeyond the vertical plane through the axis of the ,compactor wheel I8,and is operated to severthe excess tobaccov from the main body of the stream.v A straight knife ispreferred because itcan be placed'nearer to the Compactors when the tobacco is under maximum compression than can any other type of knife and hence the density of the charges being formed is more accurate. AV chute 3l is located proximate the kniferanddefiects the excess which has been removed back to the source. AAsshown, chute 3I discharges onto a Ybelt 32 which returns the tobacco to the'feeding channel, 'in a manner to be latter described. The chute is mounted for vertical adjustment so that the plane of the lip adjacent yknife '30 may always be coincident therewith. `In, the embodiment-shown, brackets Slarare fixedv to table S and yare provided with elongated slots -3Id through which pass bolts-3lc projected through the bent ends of a bar 3Ib secured to the underside of chute 3l. Wing nuts `3le on bolts `3Ic secure the chute in adjusted position. The tobaccopassingunder the knife 30- isnow of uniform ,density and correct size .-andthicknessto make the bunch, this layer of tobacco being advanced forward and acted upon by a corrugated cutter 33 which may be of the type shown in the Bronander patentabove referred to (Fig. 1) which severs a length from the layer of tobacco to produce a complete bunch. In the illustrated form, knife 30 comprises a reciprocating serrated edged blade which is adjustably mounted in order to provide means for varrying the thickness of the layer advanced to the cutter 33.

The shaft 35, of motor 33, Fig. 1, is equipped with an actuator 31 carrying a crank pin 38 on which is loosely mounted a link 39 connecting to one end of an arm 40 fulcrumed at 4l in a bracket 4l?) mounted upon bed B, Figs. 5 and 8. The lower end of arm 40 h-as a slot 42 engaging a pin 43 carried by an arm 44 integral with the U-shaped frame 45. Arm44 together with arm 46, which is also part of frame 45, carries the knife 3U, Fig. 1. Blocks 41 and 48 which support and guide the arms 44 and 46 in their to and fro motion are adjustably mounted on the bed B in order to provide for adjusting knife 30 vertically to vary the thickness of the tobacco stream passing to the bunch cutting device. Fig. 1 shows the adjustments generally, whereas Fig. shows them in detail, although as applied only to one block since the construction of block 48 is identical only one will be described. Block 41 is mounted on a bracket 41a fixed to the bed B, and is furnished with an elongated slot 41e through which projects a screw 41h carried by bracket 41a. A wing nut 41d holds the assembly in adjusted position.

The filler tobacco on reaching the charge forming corrugated cutter 33 is acted upon by a plate 53, Fig. 1, which compresses the tobacco and retains its position while the cutter 33 severs a bunch length from the filler layer. Plate 50 is suspended from a rod 5I slidably mounted in a lug 52 of cutter bracket 53. A compression spring 5ta arrested between the lug and plate tends to normally hold nuts 5 Ib threaded on rod 5I -against lug 52. The charge having been cut, now rests on the cutter platform 55 which then descends, whereupon a pusher 56, suitably operated, as shown in the Bronander patent mentioned above, passes over the platform and delivers the charge onto the rolling apron 51. In the meantime the cutter bracket 53 ascends carrying the cutter 33 and plate 50 from the filler layer.

Fig. 6 illustrates one way in which complete bunch charges may be forwarded directly to bunch forming mechanism and comprises the platform 53 and follower 59 shown in the position they occupy when a charge has just been moved from the cutter platform 55 on to the rolling apron 51 overlying the platform 58. The platform and follower then move downward, by means similar to those disclosed in the patent to Bronander, No. 1,563,333, granted December 1, 1925, the follower moving at a greater rate of speed than the platform in order to overtake the charge being lowered before the platform reaches its lowermost position. As the platform approaches the end of its downward movement, the loop is formed in the rolling apron, and the lower edge of the follower 59 engages the charge C to one side of its mid-section. A little further, downward movement of its parts results in spreading or fanning out the leaves of the charge C and in simultaneously converting said charge from its initial substantially flat form to the arcuate form as clearly shown in Figl 7. As soon as this is accomplished, the follower 53 is given a rapid upward movement so that the loop forming roller 63 can come into action and roll the charge.

The eXcess quantity of tobacco scalped from the main body of filler tobacco, Figs. 1, 2 and 3, passes up the inclined runway 3i and is directed into the chute 3l which leads the tobacco onto a conveyor 32 carrying the same onto a turn-table 62. The table G2 is provided with guides 63 and 64, tending to lead the tobacco into the feeding channel formed by belts l0, Il and I2. In this manner, the scalped tobacco is returned to the belt lo and the additional tobacco required for the filler is placed on top of the previously scalped tobacco.

In the operation of this machine, it is rela tively unimportant if an excess of tobacco be fed to the feed channel since the compactor I3 and knife 3l) always automatically reduce the stream passing to `cutter 33 to uniform density and thickness, and chute 3l returns the excess back to the source for redistribution in the channel. However, if an insufhcient quantity of tobacco is fed, it is necessary to signal the operator at once in order that bunch lengths will not be formed which will result in the production of underweight cigars that will not pass inspection. In order to prevent this contingency a device has been provided for apprising the operator when less than the required amount of tobacco is being placed in the feed channel.

Referring to Fig. 2, it will be observed that when the tobacco stream is of proper thickness, cam followers 25 are held away from cam track 23h by the tobacco and Compactors 23 are resiliently forced against the tobacco by springs 21. If, on the other hand, the stream content is inadequate the cam followers will move out farther, and may engage the track 23h, in which case the compaction of the stream would not be that required, and bunches of varying density would result. For best results, therefore, the cam followers should not engage track 2Gb.

Referring to Figs. 4 and da, there is shown one form of device for preventing underfeed of filler tobacco to the channel. A bracket El@ is mounted upon shaft I3 and is adjustably fixed to bracket 26o. Bracket 6l@ is provided with two arms, one of which carries a stud 63 on which are mounted a trip finger 32, and a suitably insulated contact 54 adapted to engage with a contact 61 fixed to stud 33 carried by the second arm. A light spring 65 holds the trip finger in contact with rollers 56 mounted on the studs that support the cam followers 25, so that whenever an insufcient supply of tobacco has been placed in the channel and in the rotation of the wheel t8, as followers 25 move off cam 23, springs 21 will force Shanks 22 outward, thereby causing rollers 65 to swing finger 32 and bring contact arm 64 into engagement with contact 31 to close a circuit through battery 33, wires 10, and 1| connected to the contacts and ring a bell connected in series in said circuit. If desired, other signalling devices such as a light, etc., might be used with equal success.

The several means referred to may be varied in construction within the scope of the claims, for the particular device selected to illustrate the invention is but one of many possible concrete embodiments of the same. The invention is not, therefore, to be restricted to the precise details of the construction shown and described.
