FIG. 2 shows an outline of a conventional apparatus using an aluminum release plate. The film of the roll 1 placed on the film placing roller 2 is fed out by the film driving roller 4, and then the film guide roller 5,
6, through the film feeding roller 7, the former 9 is opened on one side, and after the packaged object is inserted between the films from this opening side, the film is heat-sealed by the heat-sealing device 12. After that, the film is thermally shrunk by the hot air tunnel 13, the non-package is sealed, and the packaging is completed. The delivery of the film after the film drive roller 4 is driven by a motor (not shown). In order to peel off the opening of the half-fold film, an aluminum peeling plate is provided between the film placing roller 2 and the film driving roller 4, and the peeling plate is inserted between the films here. Is peeled off.

[0004] However, if the half-fold film has a slight self-adhesive property, even if the film is peeled off in front of the guide roller, the film is again blocked while passing through several film guide rollers, and the former film is blocked. Will not open in front of you. Further, since the film has a high resistance to peeling off the film immediately before entering the former, the film cannot be pulled by the ear processing chain, causing a problem that the ear processing chain idles. Furthermore,
There is also a problem that the film is entangled with the aluminum film release plate.

[0005] On the other hand, in the method in which compressed air is blown out from a round pipe to peel off the film, the speed at which the half-folded film is fed is faster than the speed at which the film is peeled, so that no effect can be expected. . Further, the film using the anti-blocking agent has a problem that the anti-blocking agent adheres to the packaging machine and causes mechanical trouble.

SUMMARY OF THE INVENTION Accordingly, the present invention provides:
It is an object of the present invention to provide a half-folded film opening device which does not cause such a problem. A woven cloth having good slipperiness and abrasion resistance is provided between a film feeding roller 7 and a former 9. It is characterized by adopting a configuration in which a release bar formed by the woven fabric is provided at a portion fixed to the support material and in contact with the film. The opening portion of the half-fold film is opened so as to be spread by such a peeling bar, and the movement to the former portion is performed smoothly without any resistance. Along with this, the conventional peeling plate provided between the film placing roller and the film driving roller causes entanglement of the film,
Removed.

The peeling bar used in the half-folded film opening device of the present invention is made of a woven cloth which is hard to be scratched on the film surface, has good slipperiness, and is abrasion-resistant, and is made of an aluminum material or a general material for the purpose of weight reduction. The woven fabric is used so that the portion in contact with the film is formed by the woven fabric. As described above, by using a woven fabric having good slipperiness in a portion of the peeling bar that comes in contact with the film, the disadvantage of the conventional aluminum peeling plate that the film is easily entangled is solved.

FIG. 1 shows an outline of the heat shrink wrapping apparatus incorporating the half-fold film opening device of the present invention, and FIG. 3 shows an outline of the half-fold film opening device of the present invention. The opening device for a half-folded film according to the present invention is characterized in that the peeling bar 8 is provided between the film feeding roller 7 and the former 9. The flow of the film in the heat shrink wrapping device having the half-fold film opening device of the present invention will be described with reference to FIGS. The film is fed by the film driving roller 4 from the half-folded film roll 1 placed on the film placing roller 2, and is sent out from the film feeding roller 7 via the film guide rollers 5 and 6. Next, the half-folded film is peeled by the peeling rod 8 so as to push open the opening side, and smoothly moves to the former 9. The former 9 is formed of two parallel triangular plate-like members, and the former 9 turns the film upside down and opens one side largely. Here, the articles to be packaged are supplied by the supply conveyor 14 from the direction of the arrow in FIG. Next, the film is thermally fused by the thermal fusion device 12. Thereafter, the packaged product is sent to the hot air tunnel 13 by the discharge conveyor 11, the film is thermally contracted, the packaged product is sealed, and the packaging is completed.

FIG. 4 shows an example of the structure of the peeling bar in the half-folded film opening device of the present invention. The peeling bar has a structure in which a woven fabric having good slipperiness and abrasion resistance is fixed to an aluminum material or a general steel material. In the structure shown in FIG. 4A, a vertically long band-shaped woven fabric 16 is sandwiched between aluminum bars 15 and several places are locked by pins 17 . FIG.
structure shown in b are bar 15 of the tubular fabric 16 aluminum material
It is covered around. The structure shown here is merely an example, and any structure can be adopted as long as the portion that comes into contact with the film is formed of woven fabric. Here, various thicknesses of the peeling bar in the vertical direction can be adopted depending on the distance between the film feeding roller 7 and the former 9 and the peeling bar 8, the height of the packaged object, and the like. 20 to 80 mm is preferred. If the peel bar is too thin in the vertical direction, the opening angle of the film cannot be made large, so that the film tends to be entangled with the peel bar. On the other hand, if the peel bar is too thick in the vertical direction, the peel resistance of the film is too large, and problems such as idle running of the ear processing chain occur. The length of the peeling bar is generally the same as the width of the half-fold film.
