Abstract

PURPOSE:To eliminate cutting failure and simplify adjustment of a cutter blade and maintenance by providing a cutter blade which comes in and out by a cam inside each cutting roll. CONSTITUTION:With an endless chain driven, a flight bar 25 is cyclically moved wherein the flight bar 25 which has cyclically moved toward each tray 1 is put between the trays 1, and a wrapping plastic film 3 between the trays 1 is folded in a U-shape. When the flight bar 25 moving together with the trays 1 reaches a cutting roller 100 position, a cutter blade 130 of the rotating cutting roll 100 is made to protrude toward the flight bar 25 by a similarly rotating cam roll 120 so that the wrapping plastic film 3 folded in a U-shape between the trays 1 is cut, the trays 1 are separated, and the wrapping plastic film 3 is heated and shrunk. Thus a slide bar and a cam bar are not necessary resulting in no cutting failure as well as adjustment of a cutter blade and maintenance can be easily performed.

Next, the operation of the packaging plastic film cutting device of the packaging machine shown in FIG. 1.2 will be specifically explained. product(
2) is housed in the tray (1) in such a state that it protrudes upward from the open top surface of the tray (1), and this tray (1) is placed on the tray transport conveyor (15) and the film feeder ((10 ) → While being transported one after another to the packaging device (see (20) in Figure 6), the roll-shaped heat-shrinkable plastic film (11) in the film supply device (10) is passed through the guide roller (12). It is fed out as a packaging plastic film (3) into the packaging device (20), and each tray (
It is placed over the product (2) of step 1), and both sides of the plastic packaging film (3) are adhered to both sides of each tray (1) using an adhesive (5) or the like. At this time, the packaging device (2
0), an endless chain (see (30) in Figure 6) is driven to circulate the flight bar (25), and the flight bar (25) that has circulated toward each tray (1) between each tray (1), and fold the packaging plastic film (3) between each tray (1) into a U-shape. Also, the flight bar (25) that started moving with each tray (1) is connected to the cutting roller (100).
When the position is reached, the rotating cutting roll (10
The cutting blade (130) of 0) is made to protrude toward the flight bar (25) by the cam roll (120) which is also rotating, and the plastic packaging film ( 3) (Fig. 2 (II)
)), each tray (1) is separated and the packaging plastic film (3) is heated and shrunk.
