renaud Application August 20, 1938. Serial No. 225,968 In Germany August 26, 1987 Claims. (Cl. 1131-21)v The present invention relates to a tobacco feed regulating device more particularly of the type used for forming loose tobacco into cigar bunches.
An object of the present invention is to control the amount of tobacco being delivered into the iiller forming press.
A further object is to provide feeding -means with a regulator which follows the vibratory feeding motion thereof. l
A further object is to coordinate the feed regulating device withthe filler pressing device.
A still further object is to control the feeding of tobacco into the filler pressing device by means of the resistance of the tobacco to the pressing member.
In order to turn out bunches for cigars from loose tobacco it is necessary that these bunches 'be made uniform as to density and weight This in turn necessitates a regulation of the feed of the tobacco so that the rate of feed will be carefully adapted to the requirements of the iiller forming device. Numerous devices have already had this as their object. The present device relates to machines in which the filler tobacco is bac'co is accomplished by pivoting a flap plate to a stationary part such as the feed hopper and allowing the free end of the plate to rest in the vibratory chute. 'I'he hinged arrangement permits the plate to follow the chute through all' of its phases of motion and the weight of the plate can be adjusted so that it will rest upon the surface of tobacco with any desired degree of drmness. If desired,-this pressure on the tobacco4 may be increased by the use of springs attached to the plate.
knife. According to the invention the quantity of tobacco fed into the former is used to control the rate of feeding from the vibratory chute. 'I'he coordination is accomplished by using the amplitude of movement of the presser as a measure. The tobacco fed from the vibratory chute falls through the opening inv th`e hollow block and lies before the presser so that the quantity of tobacco j delivered determines the extent of movement possible for the presser. Where a great quantity of tobacco has been delivered it is desirable to limit the subsequent rate of delivery until this quantity has been disposed of.
With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.
In the drawings, wherein like symbols refer to like or- .corresponding parts throughout' the several views,
Figure l is a longitudinal vertical section of the device with parts broken away.
Figure 2 is a similar longitudinal vertical section showing the operating parts in a different position. A
Figure 3 is an enlarged fragmentary view of a portion of Figure 1. f
Figure 4 is an enlarged fragmentary view of a portion of the device corresponding to that shown in Figure 3 when the operating parts are in the position of Figure 2, and
Figure 5 isa top plan view of the tobacco feeder of Figure 1.
Referring now to Figures l and 2, a tobacco supply hopper I3,is mounted-with its delivery end over a portion of a vibratory ch'ute or tray I. The floor of the chute is provided with teeth or ribs 2 which extend transversely of the chute Preferably, the hinged plate does not extend' feed lprevents feeding in large intermittent quantitles.
Thel filler forming device with which the invention is intended to be operated employs a former which consists of a hollow block -with an opening to receive tobacco and a reciprocating plungerwhich performs the actual compression of the tobacco. The compressed tobacco is cut off at suitable intervals by a reciprocating or other and serve to transmit the vibratory motion of the chute to the tobacco resting thereupon. The chute is vibrated by mounting it upon a bracket 6 which has a pair of arms 1 mounted on crank pinsv 8. The crank pins are carried by shafts 9 to which spur gears I0 are secured. The spur gears are driven by means of a third gear Il which is rotated by a belt drive I2 or the like. It will be seen that the crank arrangement causes the chute l to moveboth vertically .and horizontally. This motion causes tobacco delivered at the rear of the chute I to advancebetween the side walls 3 and 4 of the chute and to be delivered from the end Il thereof. The rear wall 5 of the chute is cut down at its upper portion to limit the amount of tobacco retained at that end of the chute. This arrangement of the back wall permits feeding an excessive quantity of tobacco at all times s o .that sumcient will be delivered for any contingency.
A guide chute I5 is located below the delivery end I4 of the chute. A shut-oif-ap I6 is mounted upon an axle I1 for movement across the delivery chute i5 to prevent flow of tobacco. The axle I1 carrying the flap I6 is connected to a lever I8 which in turn is connected through a link I9 with an angle lever 26 pivoted on the machine frame at 2|. 'I'he free end of the angle lever 20 is provided with a roller 22 which rides upon the face of cam 23 under the traction of a spring 24. The cam 23 is mounted on a shaft 25 suitably Journalled in the machine frame.
The tobacco delivery chute I5 terminates above an aperture 26 of the pressing device. This device consists of a hollow block for the channel 21 therein. Traveling in this channel 21 is a pusher 3|. Tobacco falling through the aperture 26 when the pusher or presser 3| is withdrawn receives the pressing force of the presser when=it is returned to its forward position. The aperture26 is provided with a gate or cover 28 which is pivoted at 29 and controlled by a connecting rod 30 actuated by a cam or other means (not shown). In the presser at the forward end 32 of the compression chamber a knife 33 is mounted for vertical reciprocation. This knife moves intermittently in the direction of the arrow in Figure 1 to cut off suitable portions of pressed tobacco for cigar fillers. The operation of this cutter is well understood and forms no part of the present invention and it is theref' fore not shown here in great detail.
The presser 3| is connected by a pivot 34 with a rod 35 which in turn is'connected to the angle lever 31 through a pivot 36., 'I'he angle lever 31 is pivoted on the machine frame at 38 and carries a roller 46 which rides'on the surface nf the cam 4I' under the traction of va spring 39. The* cam-4I is mounted on the same shaft 25 with the cani 23 and it will be appreciated that the cam 4I produces the pressing of the filler by swinging the lever 31 about the pivot 38 and reciprocating the presser 3|. 'The motion of the presser 3| is regulated by the following means: a slotted arm 43 is pivoted to the rod 35 and the lever 31 at the pivot 36. Through the slot 42 of the arm 43 a pin 44 mounted on the end of the lever 45 extends. The lever 45 is pivoted to the machine frame at 46 and has a braking device which may consist of a spring or other frictionally urged pin 41 which rubs against the frame and impedes swinging of the lever 45. The pin 44 has a proiection carrying a. roller 48 which extends laterally from the arm and projects into the plane of motion of a cam` carried upon the arm 49. The arm 49 is itself fastened b v means of screws 5I or the like to an angle lever 52 pivoted to the machine frame at 53. The lower arm of the angle lever 52 carries a roller 55 which rides upon the cam 56 under the traction of the spring 54. The upper end of the angle lever 52 connects to a rod 58 by means of the pivot 51 for the purpose of operating the tobacco regulating plate.
The regulator consists of a plate 64 hingedly mounted at 65 upon the tobacco hopper I3. The
weight of the plate is such that it rests firmly upon the tobacco when left free. The outer end of the plate 64 is provided with a hook 63 beneath which a finger 621s adapted to lie. The
'will thus be seen that a high point on the cam 56 will cause the nger 62 to raise the hookv 63 of the plate 64 to permit unimpeded feeding of tobacco from the chute. f h
As shown in Figure 5 the plate 64 is narrower than the chute I so that the plate lies only upon the bulk of the tobacco being fed and does not entirely stop the flow of tobacco.
It will be seen that the cams 23, 4| and 56 are all mounted upon the shaft 25 and are operated together by any suitable drive means.
The operation of the device is as follows: the vibratory chute is. as described, adapted to supply a greaterl amount of tobacco than can be used in the compression device. In operation, the shaft 25 is rotated in the counter-clockwise direction as shown in the arrow in Figure 1. As this is done the cam 4| rotates and its high portion 66 strikes the roller 40 swinging the lever 31 in a clockwise direction so that the presser 3| is `withdrawn in the direction of the arrow in Figure 1. As soon as the front face of the presser has passed the aperture 26 the closure gate 28 is swung out of the way by approximately 90 in the direction of the arrow to open the aperture. This gate 28 is swung in coordination with the presser by any suitable means (not shown).
Immediately after the presser 3| is Withdrawn the projecting part of the cam 23 strikes the roller 22 of the lever 20. As aresult of this. the closure flap I6 is swung downward to open the feed chute I5. Thereupon the tobacco accumulated upon the flap I6 drops through the aperture 26 into the presser channel 21. The cam 23 continues to rotate and the roller 22 drops from the high portion down to the normal face of the cam lifting the iiap I 6 to horizontal or closed position. The closure gate 28 for the aperture 26 is then closed and the cam 4I now arrives at the position in which the cut away or low part 61 comes beneath the roller 40. 'I'he traction spring 33 then swings the lever 31 in a counter-clockwise direction and returns the presser 3| to its upward position thereby pressing tobacco to the form of the channel 21. Accordingly, as the amount of tobacco in front of the presser 3| is greater or less the presser in its terminal position will lie more or less close to the knife 33. In Figure 1 a small quantity of tobacco lies before the presser 3|. In that case, as shown particularly in Figure 3, the pin 44 lies in position to place its roller 48 upon the cam face 56 of the arm 49. As in this position of pin 44 the recess of the cam 56 lies below the roller 55, as shown in Figure 1, the lever 52 cannot swing to drop the roller onto the cam because the arm 49 connected to the lever 52 is supported against counter-clockwise swinging by the roller 48 of the pin 44.
When the parts are in the relation shown in Figure 1 feeding of the tobacco takes place uninterruptedly.
However, on the other hand, as shown in Figure 2, the tobacco supply V in front of the presser 3| becomes too great, then, when the cam disk 56 rotates to the position shown in Figure v1, the
the tobacco.
After a suitable dwell in the cam 56 a high portion again presents itself and the arm V52 is swung in a counter-clockwise direction, the ap 64 is raised and feeding is re-commenced. In this way feeding of tobacco to the filler pressing device is kept, constant. If the feeding is normal as shown in Figure 1 the flap plate 64 is retained However, if on the other hand, an overopen. abundance of tobacco drops through the aperture 26 when the iap I 6 is opened, then the feeding of tobacco will be greatly cut down by permitting the plate 64 to close.
From the foregoing description of an embodiment of the invention, it appears that the improvements consist in 'providing Ithe shaking chute of a cigar machine with a shut off member which is associated with the delivery end of the shaking chute, and which in its operative position follows the movements ci" the shaking chute; the shut off member extending only over a portion of the width of the channel of the shaking chute. In the embodiment, the shut off member consists of a plate which is hinged above the shaking chute, and which in the position for impeding the tobacco feed, places itself sloping obliquely downward in the direction of the tobacco ow, with its free end upon the delivery end of the shaking chutein consequence of its own weight, and if necessary with the employment of additional loading by a weight or spring. Also, the tobacco passes through an aperture of the channel wall into a compression channel in which the tobacco, by means of a yielding forwardly-moved pusher or the like, is conveyed to a cut off contrivance associated with the end of the channel and the pusher by means of feelers or the like, and controls the tobacco feed in such a way that in case a certain quantity of tobacco supply in the channel is exceeded, the excess feeding of tobacco is impeded, this being arrived at by a cam controlled feeler member 50 which coacts with a projection 48 or the like, attached to the reciprocating pusher 3| or its rod system, 35, 43, t5, and at the same time is connected, by means of a rod system, 558-62, with the shut ot member 64 associated with the shaking chutev I in such a Way that in case the tobacco supply is exceeded, the fe'eler rod system is shifted into a position in which the shut off means 6d can pass into the operating position.
Finally, a structure has been described in which the inflow aperture of the compression channel is closed by a. closure piece during the compression stroke, characterized by the fact that in the tobacco feed shaft i5, terminating in the compression channel aperture 26, a flap I6 is built in, said flap i6 opening after the opening of closure 28' and closing before the closure 28 has been closed.
It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention Without departing from the spirit thereof, such changes,
andmodications being restricted only by the scope of the following claims. l
