Description

[Detailed description of the invention] "Industrial application field" The invention is suitable for transporting long thermoplastic resin sheets or films (hereinafter simply referred to as "sheets") wrapped around a core. This relates to a post pallet with a new structure.

"Prior Art" Thermoplastic resin sheets are often wound around a core and transported in the form of a roll. In particular, when the diameter of the roll is small, a post pallet (see JIS Z0106), as shown in a perspective view in FIG. 3 or 4, has been used as a loading device and an auxiliary device during transportation.

``Problems to be Solved by the Invention'' However, such post pallets themselves do not take any consideration to protect the articles, so even though they are made of thermoplastic resin sheets, their surfaces may be soft and easily damaged. If the surface is adhesive or tacky, the roll may be deformed during transportation due to contact with other rolls or under pressure from loading, or the sheet surfaces may stick to each other, causing the sheet to peel from the roll. There were problems such as it being impossible to rewind.

In order to solve this problem, the rolls have been placed one by one in a moisture-proof fiber drum and then loaded onto a post pallet for transportation. However, with this method, due to the strength of the fiber drum, it is difficult to transport a long sheet several hundred meters long by winding it into a large diameter roll. Even if it were possible, the work of packaging it would be extremely complicated.

The inventor of the present invention has developed a long thermoplastic resin sheet with a soft surface that is easily scratched, and also has adhesive and adhesive properties, without coming into contact with other rolled rolls, and without applying pressure due to loading. The purpose of this project is to provide a post pallet that can be transported while being wound around a core without being damaged.
As a result of intensive study, we arrived at this idea.

``Means for Solving the Problems'' The gist of the present invention is that in a post pallet for thermoplastic resin sheets or films wound around a winding core, four Book post 2, 2′, 2″,
