Definitions

  • Another object of this invention is to provide a clamping mechanism which has its jaws opened by a relative upward motion of .an extension of one of the jaws.
  • Still another object of this invention is to provide a bunch clamping mechanism whose jaws remain ⁇ open for a period of travel after releasing a bunch to the wrapping rnechanism.
  • a further object of this invention is to provide a simple, rugged, gently acting, and adjustable bunch clamping mechanism having fewer moving parts.
  • a feature of this invention is the provision of a bunch clamping transfer mechanism having a main jaw with an upper part pivotally mounted on a transfer arm and having a second shorter jaw pivotally secured to the main jaw below the upper part of the main jaw.
  • the second jaw is laterally constrained below its point of attachment to the main jaw so that the upward movement of a lateral projection of the second jaw causes it to pivot about its point of lateral constraint and swing7 the main jaw in the opposite direction.
  • Another feature of this invention is the provision of a latch which will hold the jaws of the clamping mechanism in the open position when they are opened to release a bunch to the wrapping mechanism and which will be inoperative when the jaws open and then close to clamp and grasp a bunch as it is ejected from the mold turret.
  • FIG. l is a front view of the bunch clamp-ing mechanism mounted on a transfer arm positioned over a broken away portion of a mold turret and with the broken away end of the transfer .arm shown in two intermediate positions and in position over a fragment of a wrapping mechanism after releasing a bunch;
  • FIG. 2 is a side view of a portion of the transfer arm with the bunch clamping mechanism shown receiving a bunch from a mold turret which is partly brokenaway in section;
  • FIG. 3 is a section taken on line 3 3 of FIG. 2;l and FIG. 4 is a perspective view of the clamping'mechanism mounted on a broken away end of the transfer arm with the trip latch of the mold turret shown below it.
  • FIGS. 1 and 2 show a portion of a mold turret T.
  • This mold turret T Patented Aug.. 7, 1962 ICC may be a conventional unit containing a number of the specially formed grooves 10 from which the bunches B are ejected on the lifting forks 12.
  • the rod 14 reciprocates vertically to eject each bunch from its groove 10 at the proper time. As shown in FIGS.
  • the turret T also has associated with it a stationary boss 22 containing a slot 2t) within which a slide 1S is-reciprocated by means of rod 24. Since the rod 24 moves upward when the rod 14 is in its uppermost position, the trip lever 16, which is fixed to the slide 18, moves upward when the lifting forks have ejected a bunch B. This trip lever is used in a manner that will be described. As is further shown in FIG. l, the bunches B are transferred to a wrapping mechanism W which may be of the type shown in Wheeler Patent 2,675,810. Since the particular mechanisms T and W do not form an integral part of this invention, .any additional description of their structure and function is not deemed necessary. It is to be noted, however, that the movement of the trip lever 16 is cooperatively utilized in the invention.
  • FIG. l also shows the central post 26 to which the transfer arm 28 is pivotally attached by the shaft v30.
  • a mechanism which is not shown swings the transfer arm 2S about the shaft 30 from position I to position IV and then back again.
  • the transfer arm 28 also has associated with it a conventional chain and sprocket or other type of drive, such as shown in Clausen Patent 2,334,174, to irnpart a parallel motion t-o the shaft 17 which is journaled in the end of the transfer arm.
  • a positioning arm 19 is xed to the shaft 17 by its heavier shank portion 23 by any suitable means such as a set screw. Since the shaft 17 has a parallel ino-tion imparted to it, the positioning arm 19 a1- ways remains vertical in all positions lof the transfer arm 28.
  • the shaft 17 rotatably passes through the heavier upper portion 32 of the main jaw 31.
  • the lower offset portion 33 of the main jaw 31 has the bunch clamp 40 fixed to it.
  • a small shaft 34 is fixed horizontally within the main jaw with a set screw or other suitable means to protrude a short distance on either side.
  • the second jaw 35 consists of two side portions 36 and 37 which are mounted on the shaft 34 and joined at their lower ends to which the bunch clamp 41 is secured.
  • a pin or fulcnnn 25 projects from side 36 of the second jaw and extends into the slot 38 ofthe positioning arm 19. This slot 38 prevents any lateral movement of the pin 25.
  • a positioning arm 42 formed of sheet metal may be fixed to the transfer arm extension 43 to position the mouth piece end of the bunch B as it is held between the bunch clamps 40. and 41.
  • the mouthpiece 44 may be thrust onto the bunch by the mouthpiece holder 4F* as shown in the patent to Halstead No. 2,827,904 dated March 2'5, 1958.
  • An additional positioning guide 46 is shown fixed to the main jaw 31 to position the front of the bunch.
  • This clamping mechanism operates as follows. Referring again to FIG. 1, as a bunch is ejected and raised on the lifting forks 12, the trip lever lorrises to its uppermost position.
  • the pin 48 which projects from theside of the second jaw 35, is urged upward as it contacts the trip lever 16.
  • This motionfto the left of the upper part of the second jaw moves the shaft 34- to the. left to pivot Ithe entire main jaw 3'1 to the left about the' shaft 17.
  • the more forwardly extending portion of the shaft 17 is of a lesser diameter than the rearwardly extending portion so that the shaft 17 has a shoulder.
  • the latch 52 rests against this shoulder so that it is positioned along the shaft 17.
  • the light torsion spring 50 shown in FIGS. 2 and 4, connects the extension 51 of the transfer arm 28 to the latch 52.
  • the spring 50 As the transfer arm moves through positions II and III of FIG. l, the spring 50 is under no tension and moves the freely turning-latch 52 around until it is stopped by the dowel pin 53 which projects from the upward extension S4 of the second jaw.
  • the spring 5t? exerts an increasing torque on the latch 52.
  • the second jaw 3S pivots in the same manner that has been descirbed in position I to open the jaws. This releases the bunch B to the wrapping mechanism W.
  • the pin ⁇ 53 on the upward extension 54 moves closer to the shaft 17 to be secured by the latch 52 which is urged downward to hook about it by ⁇ the torsion spring 50. Therefore, as the bunch clamp mechanism moves upward from position IV, the latch 52 holds the jaws open.
  • a release pin 58 projecting from the exten-- sion 51 of the transfer arm 28 rotates relative to the clamping mechanism.
  • the release pin 58 reaches the latch 52, it raises it releasing the pin 53 and allowing the jaws to close.
  • the spring 50 or the release pin 58 then turns the latch 52 ⁇ away from the pin 53 so that the jaws may freely open and close in position I where the latch will be inoperative. It may be seen in FIG. 2 that the pins 53 and 58 each extend somewhat less than half way through the thickness of the latch 52 so that the ends of the pins will clear and pass each other as the latch is released.
  • This particular bunch clamping mechanism has many advantages. Since it has only three moving parts with lassociated elements fixed to them, it is rugged in construction, easy to disassemble, and simple to maintain. The only moving parts are the two jaws and the latch. In addition, this clamping mechanism is easily adapted to be used with existing cigar making machinery with minimum alterations.
