Definitions

  • the present invention relates to a swingable claw for a wrapping machine, which acts to fold the end face of soft wrapping paper in a process of wrapping a product with the paper.
  • a conventional wrapping process shown in Figs. 2 to 8 is effected.
  • soft wrapping paper P cut to prescribed dimensions is moved down into a wrapping passage.
  • a product A to be wrapped such as a pile of cigarettes is pushed forward into the soft wrapping paper P by a pusher 1 and the product and the paper are passed through between an upper and a lower guide plates 16 (shown in Fig. 9) so that the paper P is wound as U on the product A.
  • the product A and the paper P are pushed forward further by the pusher 1 so that a swingable claw 2 waiting in a closed position performs the front end face folding P 1 of the paper P, as shown in Fig. 4.
  • the product A and the paper P are then pushed forward furthermore so that a guide plate 3 holds the end face folding P 1 of the claw 2.
  • the pusher 1 finishes pushing the product A and the paper P forward and the swingable claw 2 is opened to a non-folding position, as shown in Fig. 5.
  • a lower portion folding plate 4 is then moved up to perform a lower portion folding P 2 , as shown in Fig. 6.
  • An upper portion folding plate 5 is then moved down to perform an upper portion folding P3, and the lower portion folding plate 4 is simultaneously moved down, as shown in Fig. 7.
  • the swingable claw 2 is then turned to the closed position to perform a rear end face folding P 4 , as shown in Fig. 8.
  • the present invention was made in order to solve said problem.
  • the purpose of the present invention is to provide a swingable claw for a wrapping machine, which makes it possible to neatly perform the rear end face folding of soft wrapping paper exactly along its folding line.
  • the present invention is hereinafter described in detail referring to an embodiment.
  • the rear portion of a swingable claw 12 as to the direction of proceeding of a product A to be wrapped is pivotally coupled by a pin 13 to the support plate lla of a turnable arm 11 secured on a turning shaft 10, and the free front and 12a of the claw 12 is urged in such a direction as to open away from the support plate lla, by a helical spring 14 provided between the free front end 12a and the support plate lla.
  • the degree of opening of the swingable claw 12 from the support plate lla is adjusted by a stopper 15 secured on the rear portion of the support plate by a screw.
  • a support mechanism is provided for the pasted upper folded portion P 3 of soft wrapping paper P and an upper guide plate 16 has a vacuum suction port 16a.
  • paste 17 applied to the upper folded portion P 3 of the paper P is prevented from irregularly clinging to other portions as the paper P is wound as U on the product A.
  • the turnable arm 11 and the swingable claw 12 are moved between an opened position shown by a full line in Fig. 1 and a closed position shown by a two-dot line therein, respectively.
  • the closed position the free end 12a of the swingable claw 12 is closed by the wrapped product A against the helical spring 14.
  • the swingable claw 12 When the swingable claw 12 is in the closed position and the wrapped product A is pushed out by a pusher, the free end 12a of the swingable claw is pushed down by the wrapped product A against the helical spring 14 and simultaneously performs a front end face folding P 1 .
  • the outer edge Q of the free end 12a whose degree of opening is previously.adjusted by the stopper 15 takes a locus to come into contact with the folding line P 4 ' of the folded end face portion P 4 of the wrapping paper P at the rear of the wrapped product A so that the swingable claw 12 is moved to the closed position shown by the two-dot line in Fig. 1, as the claw performs the rear end face folding P 4 of the wrapping paper P and is simultaneously pushed down by the wrapped product A.
  • the rear portion of the swingable claw 12 is pivotally coupled to the support plate lla of the turnable arm 11 and the free end 12a of the swingable claw is urged by the spring 14 in such a direction as to open and is normally kept at a prescribed degree of opening, the rear end face folding of the soft wrapping paper P on the wrapped product A is neatly performed along the folding line of the paper.
