Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of packaging a coil body formed by winding a wire rod such as an enameled wire or a welding wire, or a band material into a coil shape.

[Prior Art and its Problems] Generally speaking, the means for packaging this type of coil body is to house it in a packaging bag or to wrap it in a tape-like wrapping paper. However, such conventional packaging is difficult to handle, especially when the coil body is heavy.1 For example, if the cable tie is lifted and moved by a crane, the winding condition may collapse and the product may be damaged. I was worried about this.

[Means for Solving the Problems] The method for packaging coil bodies according to the present invention is intended to solve the above problems, and includes a pallet in which the four periphery edges of the upper plate are projected outward in the form of an eave. A wide moisture-proof sheet is spread on the top surface, the coil body to be packaged is placed on top of the sheet, and a heat-shrinkable film is placed on top of the sheet, and the film is heated and shrunk, so that the peripheral edge of the film becomes the shape of the pallet. It is characterized in that the film is wrapped around the peripheral edge of the upper plate, and at the same time, the film is brought into close contact with the upper surface of the peripheral edge of the moisture-proof sheet.

[Function] The eave-shaped peripheral edge of the pallet top plate allows the heat-shrinkable film to adhere easily and reliably, and the film also adheres closely to the moisture-proof sheet, preventing moisture from entering and protecting the coil body. can. Furthermore, the pallet can support the coil body without deforming it, making transport and storage easier.

[Example] Next, one embodiment of the present invention will be described with reference to the drawings.

The pallet 1 is made of wood and has upper plates 3. The lower plate 4 is attached. The upper plate 3 is wider than the lower plate 4, and its four periphery edges protrude outward like an eave. However, on the pallet 1 of the lever, a moisture-proof sheet 5 made of foamed and elastic resin is laid.

The coil body 6 to be packaged is placed thereon so that its center line is perpendicular. Note that the coil body 6 is bound in advance using a binding pad door. Then, a sufficiently large heat-shrinkable transparent film 8 having a thickness of about 100 to 150 μm is placed thereon, and hot air is blown onto the film 8 to heat it and shrink it. Then, the peripheral edge of the film 8 is wrapped around and adhered to the peripheral edge of the upper plate 3, and at the same time, the film 8 overlaps and adheres closely to the upper surface of the peripheral edge of the moisture-proof sheet 5.

Therefore, the coil body 6 is immovably fixed on the pallet 1 by the tension of the film 8, and the coil body 6 is almost airtightly packaged by the moisture-proof sheet 5 and the film 8, so that water-tight sealing properties are created and moisture is removed. prevent intrusion. For this reason, cargo handling can be carried out even in the rain, and transport and transshipment can be easily carried out using a forklift.

[Effects of the Invention] As explained above in the embodiments, the method for packaging a coil body according to the present invention can be easily packaged with a heat-shrinkable film, so the packaging cost is low, and the coil body has water-sealing properties. In addition to providing reliable protection, the product has various advantages, such as being able to be handled by a forklift, making the product less likely to be damaged.

Claims (1)

[Claims] A wide moisture-proof sheet is laid on the top surface of the pallet, which has the four periphery edges of the upper plate protruding outward like an eave, and the coil body to be packaged is placed on top of it, and then a heat-shrinkable film is placed on top of it. The film is heated and shrunk so that the peripheral edge of the film wraps around the peripheral edge of the upper plate of the pallet, and at the same time, the film is brought into close contact with the upper surface of the peripheral edge of the moisture-proof sheet.
