Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a packaging tool, and more specifically, a packing tool that can pack and unpack bonded materials such as films and sheets with good workability, and that can be used as a product. This invention relates to a packaging tool with excellent layer protection.

[Conventional technology]

BACKGROUND ART Conventionally, manufactured films, sheets, etc. are once packaged as a bonded body, and after being transported or stored, the film or sheet is fed out for use.

These films and sheets are packaged in the form of layers of 650 to 1,600 square meters wrapped around each other to a weight of 100 to 600 square meters.

Conventionally, as shown in FIG. 5, a method has been adopted in which a shaft 31 is inserted through a layered body 29 wound around a bobbin 30 and then fixed to a shaft holder 32.

In addition, as shown in FIG. 6, a nut 34 is provided for fixing the shaft 31 and the contact layer 29 of the product.
! A method of preventing the layered body 29 from moving laterally has also been adopted.

[Problem to be solved by the invention]

However, the method shown in FIG. 5 has the following problems.

(2) Since the contact body 29 is heavy, a forklift or a hoist crane is required to pass the shaft 31 into the bobbin 30, transfer it to the shaft pedestal 32, and pack it.

■Since the shaft pedestal 32 is considerably larger than the contact body 29, a forklift or hoist crane is required to move it, and the size of the shaft pedestal is increased by the size of the shaft pedestal, which requires extra space. The number of products that can be loaded onto a truck bed, etc. is inevitably reduced, and the efficiency of loading onto the truck bed, etc. is reduced.

(2) Since the contact body 29 is heavy, it must be unpacked by lowering it from the shaft pedestal 32, pulling out the shaft 31, and removing the side plate 33, and a hoist crane or the like is required at that time.

■Since the shaft holder 32 is heavy and bulky, it is difficult to collect and store it, and the shaft 31 corresponds to the width of the contact body 29.
A shaft holder 32 is also required.

■Since the contact body 29 and the shaft 31 are not fixed, the contact body 29 may shift laterally or rotate. The winding body 29 is easily damaged and loses its commercial value.

In addition, in the method shown in FIG. 6, the nut 34 prevents the contact body 29 from moving in the lateral direction during transport, so that part of the problem (2) in the method shown in FIG. 5 is solved. Other issues remain unresolved.

The present invention has been made to solve the above-mentioned problems, and its purpose is to enable packaging and unpacking of bonded objects such as films and sheets with good workability, to reduce the bulk of the packaged objects in the packed state, and to enable the bonded objects as products to be packaged and unpacked with good workability. The purpose of the present invention is to provide packaging equipment with excellent protection.
