51 Claims.

This invention relates to detectors forcigar machines, its general. object being to provide means for controlling the operation of certain parts. of a cigar making machine, when a defective cigar hunch is forwarded to be operated on by said parts, in such a manner that losses due.

to the wrapping of defective bunches or otherwise operating on defective bunches are eliminated.

Hitherto, in the operation of cigar machines, if a defective hunch is supplied to the wrapping mechanism an expensive wrapper will be delivered by a wrapper transfer, paste will be applied to said wrapper, and the wrapper will be-applied to the-bunch, with the result that the wrapper is spoiled. Also when no bunch whatever is supplied, the wrapper is pasted and fed into the wrapping mechanism and becomes entangled therein, unless the operator is alert and notices that no bunch has been supplied. In this case the operator declutches the machine and pre-- vents operation thereof until a bunch is received, whereupon she restarts the machine,with some loss of timeand trouble.

leaf to the defective bunches, or when no bunch is forwarded, thus preventingspo-iling of expen- I sive. wrappers.

Another object of the invention is to provide detecting and control means for preventing application of paste when no normal bunch or wrapper is being forwarded tov the wrapping station. This serves to prevent fouling of parts by paste, as for. instance fouling of the. Wrapper transfer face.

A further object of the invention is to provide detecting mechanism. including. feelers operating on the head end of the. bunch or filler charge to detect empty or soft head portions, and also to provide feelers spaced along, the length ofthe cigar and individually operable to prevent the operations above referred towhenanyone of said feelers detects a defective bunch part.

Another object of the invention is. toprovide The principal object of the present invention,

of .a bunch, and to cause said instrumentalities for maintaining the wrapper supplying means or for operating parts inoperative after passage of a bunch past the detecting station. In this connection it is also a feature of the invention to provide for means automatically rehabilitating the parts rendered inoperative by the passage of a defective bunch when a normal bunch is ready to be operated upon.

Another feature of the invention lies in the controlling of the, suction on a cutting die and on the suction transfer receiving a leaf portion from said die to retain suction on said die andto cut oil suction on said transfer when a defective bunch is forwarded.

With these and other objects not specifically mentioned in view, the-invention consists in certain constructions and combinations hereinafter fully described, and then set forth in the claims hereunto appended.

Briefly and generally described, in the embodiment. illustrated, there is provided in combination with mechanism for supplying a filing portion of a cigar, such as a charge or a charge wrapped in a binder, devices for supplying a wrapping portion of a cigar such for instance as a wrapper or binder, together with detecting meanscoacting with said mechanism. and said devices to. incapacitate said devices when said mechanism fails to supply a normal filling portion, thereby preventinginjury to. or loss of wrappers. In the form selected for illustration, said detecting means includes a feeler and means for imparting relative movement to said filling portion and said feeler to-cause one to. engage the other. Preferably, the wrapper. supplying devices include a suction wrapper transfer and said detecting means controls the suction to said wrapper transfer. In the machine selected for illustration, which is provided with a paster for applying paste to said wrapping portion, said detecting means is arranged to incapacitate the paster when no wrapping portion is supplied and when no normal bunch is for- Warded, thereby preventing fouling of the transfer. In the improved form shown, means are provided automatically to separate defective bunches from normal bunches. The above mentioned means and parts may be widely varied in constructions, for the particular device selected to illustrate the invention is but one of many possible concrete embodiments of the same. The invention, therefore, is not to be restricted to the details of the structure shown and described for illustrative purposes.

Referring now to the machine illustrated in the drawings, the bunch B ejected from one of an endless series of bunch shaping pockets 5a of the bunch mold turret 5 is carried by a swinging transfer arm 6 to the wrapper applying device I. The end positions 6 and 6" of the transfer arms corresponding to the bunch positions B and B" are shown in dotted lines. At the same time, a wrapper W is cut on the wrapper die 8 and taken to the wrapping device I by a wrapper carrier 9. The wrapper W is held by suction on the die 8 while being cut and on the wrapper carrier While being transferred. The die 8 and carrier 9 for this purpose communicate with a common suction chamber I controlled by slide valves I and I2, the valve II being closed and the valve I2 opened by a cam 54 when the wrapper W is being picked up by the perforated suction face 9a of the wrapper transfer or carrier 9, as shown by dotted lines II and I2. To chamber I6 is connected a suction pipe I3 in which the suction is continuous. The wrapper carrier 9, which is rotatably mounted on a hollow jointed arm I4 swinging on a shaft I5 in a hollow column I6, travels from position 9 on the die 8 to position 9" at the wrapper device I. In position 9", before reaching the wrapping device, one end of the wrapper on the carrier receives a daub ofpaste from a dauber H which is raised from a paste pot I8 at the proper time.

In order to prevent the wrapper carrier 9 from picking up a wrapper and paste, or in the absence of a wrapper, being fouled by the paste, in case no bunch or an imperfect bunch has been delivered to transfer 6, a row of detector feeler fingers I9 is placed adjacent the path of the bunch carried by transfer arm 6, these feelers being pivoted on a pin and each being provided with a spring 2|, the tension of which is adjustable by a threaded nut anchoring the spring to a bar 22 and adapted to yieldingly urge the feelers with a proper predetermined pressure toward the bunch B. The feelers I 9 are normally held in a neutral retracted position on pin 20 by levers 23 pivoted on a pin 24 and bearing against them through the action of springs 25, each feeler for this purpose having a stub projecting downward from its pivot point and engaging the end of one, of the levers 23, thus in turn holding the levers 23 in their normal horizontal position on their pivot pin 20 as long as the feelers I9 remain in place, the tension of the springs 25 being made sufficient as compared with the rather light tension of springs 2|, to accomplish this result.

At the moment when the arm 6 crosses the path of the feelers I9, but in proper time to engage the bunch if one is advanced in proper succession, the pressure of each of the springs 25 is momentarily taken up by a cam 26 which slightly raises a roller 21 of a lever 28 connected by a rod .29 to each of the levers 23, so that the feelers for this moment are free to swing against the bunch B. The levers 25 are pivoted on a shaft 30 and are connected by links 3| with latches 32 mounted on a pivot 33 and adapted to engage with a pin 34 in cam lever 35 which by a spring 36 is held in tension on fulcrum shaft 31 and through links 38 and 33 actuates the slide valves II and I2 of suction chamber III. The rods 29 are connected by links 40 to lever 3| pivoted on paster bracket 42 and carrying stop screws 43 which limit the up-motion of the dauber Il' so as to deliver just the right amount of paste to the wrapper.

When the transfer 6 carries a perfect bunch, then at the critical moment when the springs 25 are arrested by cam 25, the freed feelers I3 are held by the passing bunch B in their neutral position and at the next moment, when cam 26 has released springs 25, are again locked in place by the friction of levers 23. Thus after one cycle of operation of the machine and until a normal bunch is forwarded, the parts incapacitated by the operation of the feelers are rehabilitated. But when the bunch B in transfer 6 is too soft or when there is no bunch in the transfer arm, one or more of the feelers I9 will swing out of their neutral position, until arrested by stop screws 44 provided for this purpose, and the corresponding levers 23 on the release of springs 25 will turn on their pivots, causing cam levers 28 to descend to positions 28 thereby closing through links 3| one or more of the latches 32 over the pin 34 and at the same time turning through links 40 one or more of the levers 4|.

The closing of any one of the latches 32 prevents the cam lever 35 from actuating the valves I I and I2 when the wrapper carrier is in position 3 to receive the wrapper for the imperfect or missing bunch which has permitted the tripping of any of the levers 23. Also, the turning of any one of the levers 42 causes the dauber I! to be arrested by the then depressed stop screws 43 before it has reached the level of the wrapper carrier and the latter is thus kept clean for the next wrapper. Thus the cigar bunch is automatically inspected at spaced points along its length, including its head end, a part of the bunch which is critical in the production of good cigars.

The lever 35 and the stop screws 43 remain in their down-positions until the next normal bunch B transferred by arm 6 has reset the tripped feelers I9 by engaging with them and turning them back into neutral position on its way to the wrapping device. Since at this moment of engagement the cam 26 raises the levers 28, the feelers I9 and the levers 23 come into engagement and hold each other in their normal positions. The latches 32 are thus released and the stop screws 43 are raised to their normal positions so that a wrapper is properly fed and pasted for the coming bunch.

The bunch mold turret 5, wrapping device I, and wrapper carrier 9 are actuated from a main cam shaft 45 of the cigar machine by chains 46, 41, and 48, respectively, and the transfer arm 6 carrying bunch holding spring clips or gripper fingers 6a and paste dauber I! are operated by levers 49 and 50 controlled by cams on shaft 45, so that .all parts of the machine work in synchronism. A cam 54 on shaft 45 actuates lever 35 downwardly against spring 36.

The guide rod 5| of the dauber rests on a spring 52 carried by the lift rod 53, this spring taking up the motion lost by rod 5|. when the latter engages screws 43 before the end of the stroke of rod 53. I

As shown in Figs. 1 and 3, the ejector pins 55 are moved to a position shown at 55' to eject the bunch B into the grip of the spring clips or gripper fingers Go for movement on the transfer arm 6. These ejector pins are supported in a block 55a. which is vertically reciprocated by an arm 56 pivotally connected to the block and given an oscillating. movement by rack 58 .and pinion 51. The rack is reciprocated by means of a lever 60 having a cam roller 6| in engagement with a cam 62 secured to the turret shaft 63. This ejector pin operating means may be of any other suitable construction for operating the pins in proper timed relation to the movement of the turret, such as that shown in the patent to Rundell, No. 1,838,157, dated December 29, 1931, to which reference is made for further details of the ejecting mechanism and mold turret proper.

One of the principal advantages of the defective bunch detecting mechanism set forth herein is that it makes'possible and renders more reliable a cigar machine in which the bunches are automatically delivered from the bunch making end wherein, for example, scrap tobacco is separated into charges and rolled in a binder, to the wrapping end of the cigar machine wherein the formation of the completed cigar from the bound bunch is completed. Hitherto, there has com monly been a hand transfer from the bunch making machineto the wrapping and shaping part of the machine, necessitated to a large extent because. of the need for a hand inspection of the bunches through feeling of the same by the operator prior to inserting them in, for.example, the pockets of a shaping mechanism. By providing an automatic inspection device acting on the bunchlintermediate the applying of the expensive wrapper and the forming of the bunch consisting of abound: charge, it becomes possible to eliminate the, hand transfer between bunch making and wrapping .machines. It should, however,.be clearly understood that the present inspection device and its combination with the wrapping and pasting mechanisms have value outside of the general combination with the bunch wrapping mechanism, since they provide an automatic inspection not hitherto available in connection with these elements.

Referring to Fig. 1a showing the machine parts to the right of those shown in-Fig. 1, with which they are intended to cooperate, a container 64 constituting a source of supply of scrap tobacco has travelling within it an endless chain conveyor 65 having pockets 65a which take up a quantity of .tobacco sufficient for one bunch charge. This chain travels over sprockets 66 and 61 and an idler sprocket 68 positioned to invert the pockets and deliver tobacco into the chute 19 and thence to the measuring chamber H within which the tobacco is retained by a hinged door 12. The. sprocket 66 is driven in timed relation to the cigar machine by a chain 69 connected to a sprocket on the main drive shaft 45. A vertical-shaft l3 mountedfor. vertical reciprocation in a bearing 14 supports through bracket 15 a plunger lfiwhich is rela-' tively movable with respect to the chamber II,

through which it passes to deliver the tobacco charge T past the gate 12 into the pocket ofthe bunch rolling apron 82. A spring 111 interposed between a bracket element of the measuring chamber H and the bracket 15 serves to impart a vertical motion to said chamber depending onthe position. of. the lower end of the keyway 13a. within which a set screw 13b engages. Thus, the spring 11 serves to keep the. measuring chamber at a position determined by said lower end of the keyway while permitting relative motion of the plunger 16 to eject the charge. The plunger 13 is operated by any suitable means such as a cam lever 18 pivoted at 19 and having a cam roll engaging cam 8i. The door 12 is suitably operated by striking a stationary pin 12asecured to any stationary part of the bunch machine frame.

The rolling apron 82 rolls the charge T over the rolling table 83 on which a binder leaf has been previously placed, in a manner well known in this art, by means of a rolling pin 84 given its operative movement by means of a lever 86 pivotedat 8l'and actuated by a link 88 connected to a lever 89' operated through cam roller 9| by cam 8|. Lever 89 is suitably pivoted on a bracket 99'. Guides suitably guide the rolling pin at projecting end portions thereof over the rolling table 83. The bound bunch consisting of the charge rolled in the binder is ejected by an apron as shown in Fig. 1a, into a chute 92 against a guard 93. The bunch is seated in the pocket Baof the'shaping turret 5 by a plunger 94 supported by bracket 95 which preferably extends diagonally out of the path of the transfer 6 and is secured to a plunger rod 96 guided in a bearing 91 and actuated by a lever 98 operated through roller I09 from the cam 62. The lever 98 is suitably fulcrumed at 99.

It is noted that the failure of the wrapper car rier or transfer to remove the cut wrapper leaf from the wrapper die constitutes a visual signal to the operator that a defective bunch is passing through the machine, and other signal means may of course be operated by the inspection device to inform the operator as to the presence of a defective bunch.

While as used in the trade the terms cigar bunch and cigar wrapper are commonly employed. in a narrow technical sense, as used in the claims, these terms .are to'be employed in their broad dictionary meaning in the absence of specific language to the contrary. Thus, the term cigar bunch as used in the claims may refer to a charge without a binder, or to the charge in a binder known to the trade as a cigar bunch. Similarly, unless otherwise specified, the term cigar wrapper. or cigarwra'pping is not to be limited to the spiral outer'wrapping but may refer to a binder wrapped about the charge, or to such binders or wrappings as constitute the sole wrapper for cigars, such as Toscani cigars.

In. Figs. 4. and 5, inaddition to the construction shown in Figs. -1 and 1a, an addition is provided in which the cigar bunch is released from the bunch transferring or advancing means, as for instance'by opening the grippers 6a when the detector feeler 19' by its movement indicatees that said bunch is defective.

In the embodiment illustrated in Fig. 4, a cross bar I92 having a dependent end portion, which is attached to each of the gripper fingers 60a, is

provided. The detector .feeler I9 is provided on piece I04 into the path of travel of the dependent portion of the cross bar I02 and thus swings open the gripper finger 6a, releasing the defective bunch which drops into a container I05.

A suitable circuit is provided forv energizing the solenoid I03 when the contacts IOI and IOIa. are brought together. When contact is made between MI and mm, the current in the primary III of a transformer energizes the secondary II2 of said transformer and the current from the secondary passes through conductor H5 to the contacts IM and mm. The current now passes through contacts IN and IOIa and wires IIS and I20 through solenoid I03 and back through wires I2I and I I! to the secondary I I2. As long as contact IOI remains closed current passes to solenoid I03. Thus, the core I04 remains in the path of the dependent portion of the member I02 for the purpose of opening the gripper fingers 6a if a defective bunch is being carried. In the next cycle of operation of the machine passage of a normal bunch will push the feeler I9 down, open contacts I0 I-I0 Ia, causing armature I03 to drop out of gripper opening position. It is noted that the operation of the locking lever 23 is such that once a defective bunch has pressed feeler I9 down it is held in its lowered position until reset by engagement of a normal bunch therewith. Thus contacts IOI-I M a remain closed till the feeler is reset. On the return movement the resilient finger 6a yields enough to permit passage of the depending portion of I02 past core I04 which is somewhat champered to facilitate this action.

Current flows at all times through the transformer primary through conductors I24, I25, and I23 back to the line I I3.
