Description of the Related Art Conventionally, a nichrome ribbon or a nichrome wire is pressure-bonded to a heat-welding plastic film, and a large-capacity current is instantaneously applied to the nichrome ribbon or the nichrome wire to generate heat, thereby welding or welding a heat-welding plastic film. Welding

である。In the heat sealing apparatus shown in FIG. 5, a linear receiving rubber 72 made of heat-resistant rubber is fixed to the lower end, and the receiving rubber 72 is pressed against the heat-welding plastic film 60 so as to be vertically movable. Crimping plate 74 and crimping plate 7
4 and a seal base 78 on which a nichrome wire 76 is placed via an insulator 79 at the top, and a heat-sealable plastic film 60 disposed between the seal base 78 and the pressure plate 74 is pressed against the pressure plate. After holding the film 60 by the downward movement of the film 74, a large-capacity current is instantaneously applied to the nichrome wire 76 to weld the film 60 in a straight line or to weld and fuse it.

合している。The heat seal device shown in FIG. 6 is basically similar in structure to the heat seal device shown in FIG.
In order to make the seal shape a semi-circular shape, the pressure bonding plate 74 and the seal base 78 are curved in a vertically symmetrical semi-circular shape, and in the groove formed in the semi-circular insulator 79, the nichrome wire is replaced. A ribbon-shaped or band-shaped nichrome wire (hereinafter simply referred to as “nichrome ribbon”) 80 is fitted.

できる装置は存在しなかった。In the conventional heat sealing apparatus, a linear seal shape as shown in FIG. 5 and an arc seal shape as shown in FIG. 6 are formed. However, it is technically difficult to make them changeable from the insulator that holds the nichrome wire or the nichrome ribbon, the material of the insulator, and the structure that fixes these to the seal base. There is no heat-sealing device that can appropriately change the seal shape according to the size and shape of the package, and it is possible to perform heat-sealing and seal cutting to any desired shape other than the initially set shape. Did not exist.
【0007】そのために、被包装物の外形形状に合致し

いる。For this reason, the packaged object packaged by a heat sealing device having a seal shape that does not match the external shape of the packaged product not only has a poor finish after packaging, but also has a seal cut by the heat sealing device. When subjecting the packaged product inserted in the wrapped tube to heat shrink wrapping, the shrinked film or sheet does not adhere to the packaged product, and the film or the like partially loosens, loosens, triangles, squares, etc. The burrs or protruding portions referred to as "one" are generated, and the appearance of the package is poor, and when collective packaging or the like is performed, a sufficient binding force cannot be obtained, which causes collapse of the load.

いた。[0008] Therefore, when packaging with a conventional heat sealing device, loosened, loosened, and protruding portions of the heat-sealed and heat-shrink-wrapped film are again sealed and removed, and the package conforming to the outer shape of the packaged object is removed. And the work efficiency was degraded.

を目的とする。Therefore, the heat sealing device of the present invention can change the shape of the seal by making the shape of the seal variable, and the heat seal device of the present invention can cope with various shapes and sizes of objects to be packaged in one device. By changing the seal wire to a shape that is in close contact with the outer shape, heat sealing can be performed that matches the shape of various items to be packaged, especially when used before heat shrink packaging, the finish is beautiful, An object of the present invention is to provide a heat sealing device capable of performing heat shrink wrapping with a good yield.

接し得るように構成している。The plurality of support members 16 supported on the pins 14 protruding from the chain 12 are made of a heat-resistant synthetic resin, for example, an engineering plastic such as an epoxy resin, or a heat-resistant / insulating material such as glass or ceramic.
Not contacting the adjacent support member 16 and supporting member 16
The diameter of the support member 16 is set so that the distance between the outer periphery of the support member 16 and the support member 16 is about 0.5 to 1.5 mm. In this embodiment, the distance between the centers of the support members 16 and therefore the pins 14 is set to about 12 mm, and the diameter of the support members 16 is about 12 mm and the length is about 23 mm.
The distance between the adjacent support members 16 is set to be less than 1 mm. In this manner, by providing the support member 16 for supporting the nichrome ribbon 40 with a small interval, the displacement of the nichrome ribbon 40 when the supporting means 10 of the heating means 40 is deformed is prevented, and the receiving rubber described later is securely formed. It is configured so as to be able to face and abut with 42.

の形状と成る。When the chain 12 is deformed into, for example, a semicircle in a state where the nichrome ribbon 40 serving as the heating means is carried on the carrying means 10 of the heating means 40 having the above-described structure, the link of the link of the chain 12 is formed. A support member 16 supported by a pin 14 projecting from one side moves according to the shape of the deformed chain 12. Therefore, the nichrome ribbon 40 carried on the upper end of the support member 16 follows the semicircular chain 12 and has a similar curvature.

る。The nichrome ribbon 40 carried by the support member 16 has a flexibility generally having the same elasticity and resilience as a leaf spring, and a force for restoring the deformed chain 12 to a straight line. Works. Due to the presence of the restoring force, the adjacent links of the chain 12 are prevented from being bent sharply around the pin 14, and the nichrome ribbon 40 is prevented from being partially linearly bent.

The heat-welding plastic film 60 can be reliably welded and blown by being brought into contact with the rubber 42. In particular, since the heating means 40 has a ribbon shape, the nichrome ribbon 40
Although repeated use may cause a slight wavy habit, even in such a case, the widely formed receiving rubber 42 and the nichrome ribbon 40 surely come into contact with each other.
