Definitions

  • 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.
  • 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
  • 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.

  • Fig. 4 is a diagrammatic view in sideelevation showing. a device for ejecting defective cigarbunches.
  • Fig. 5 is a detail view in end elevation on line 5-5 of Fig. 4.
  • 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.
  • the wrapper Preferably, the wrapper.
  • supplying devices include a suction wrapper transfer and said detecting means controls the suction to said wrapper transfer.
  • 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.
  • means are provided automatically to separate defective bunches from normal bunches.
  • 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.
  • 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.
  • a suction pipe I3 in which the suction is continuous.
  • 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 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
  • 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
  • the rods 29 are connected by links 40 to lever 3
  • 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.
  • 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 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 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
  • 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.
  • the bunch making machine 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.
  • 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,
  • 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.
  • 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
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • a cross bar I92 having a dependent end portion, which is attached to each of the gripper fingers 60a, is
  • 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.
