Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention is a method for rolling a flexible sheet-like material such as a thermosetting molding material into a roll around a cylindrical core tube. Or related to a storage stand for storage.

<Prior Art> Generally, a thermosetting molding material is composed of a semi-fluid viscous liquid and glass fiber, and it is difficult to maintain its shape immediately after manufacturing. In particular, when sheet-like thermosetting molding material is wound into a roll around a cylindrical core tube for transportation and storage, if the roll diameter is 30 cm or more, it will not work if it is simply placed on a stand etc. The material of the roll is deformed by its own weight, and its cross-sectional shape loses its roundness, resulting in uneven thickness of the sheet material. For this reason, roll-shaped materials are loaded onto a storage stand made to prevent roll-shaped materials from deforming, and kept in storage for 1 to 5 days while maintaining the temperature of the materials at room temperature or around 40℃. By aging it to a certain degree, it was hardened to the extent that it would not deform under its own weight.

Here, as a method of supporting a roll-shaped material on a storage table, conventionally, a semi-cylindrical metal plate having a curvature similar to the curvature of the outer circumferential surface of the roll is provided on the storage table, and this metal plate is attached to the material part of the roll. A method of supporting the roll by placing it thereon, or a method of providing a support on the storage table and supporting both ends of the cylindrical core tube of the roll using the support have been adopted.

<Problems to be Solved by the Invention> By the way, according to the former method, since the entire weight of the rolled material is supported by the semi-cylindrical metal plate, the bottom of the roll and the edge of the arcuate metal plate, etc. According to the latter method, there was a problem that the lower part of the roll sagged downward due to its own weight and became deformed. As described above, the current situation is that no matter which storage table is used, the amount of deformation of the material cannot be sufficiently suppressed.

An object of the present invention is to provide a flexible sheet-like material roll that can store a flexible sheet-like material roll while maintaining its roundness as much as possible, and can even out the wall thickness of the sheet-like material. The purpose is to provide a storage stand for items.

<Means for Solving the Problems> A configuration for achieving the above object will be described with reference to drawings corresponding to embodiments. hand,
a pair of support members 27 that are arranged at a predetermined distance from each other and support both ends of the shaft (cylindrical core tube) 1 of the rolled material M at a predetermined height position from the floor surface;
28, a flexible sheet (canvas) 3 having a width greater than the width of the sheet-like material (thermosetting molding material) S to be stored, and both ends thereof across the line connecting the two support members 27 and 28. Two sheet fixing members (connecting members) 25 and 26 are arranged parallel to each other and fix both ends of the flexible sheet 3, respectively, and both ends of the shaft 1 are supported by a pair of supporting members 27 and 28. In this state, the upper surface of the flexible sheet 3 is configured to abut at least a part of the outer peripheral surface of the sheet-like material S wound around the shaft 1 over the entire width direction thereof. .

<Function> Both ends of the shaft 1 of the rolled material M are supported by two supporting members 2.
7 and 28, the flexible sheet 3
Since the upper surface abuts a part of the outer peripheral surface of the sheet-like material S of the roll M over the entire width direction, the weight of the roll M is distributed by the shaft 1 and the flexible sheet 6. This means that the rolled material M can be supported more easily than when using a conventional storage stand.
The amount of deformation will be reduced.

<Example> An example of the present invention will be described below based on the drawings.

The drawing is a perspective view of an embodiment of the invention.

The rolled material M is made by winding a sheet-like thermosetting molding material S (hereinafter referred to as sheet-like material) having a width of about 1 m around a cylindrical core tube 1 made of FRP. Both ends protrude from the sheet-like material S.

The support member 27 equipped with the receiver 27a is attached to the support column 2.
1 and 22 at a predetermined height position, and also includes a support member 28a.
is supported by pillars 23 and 24 at the same height as the support member 27. The strut 21 and the strut 23 are connected via the connecting member 25, and the strut 2
2 and a support 24 are connected via a connecting member 26, and by placing both ends of the cylindrical core tube 1 on the receivers 27a and 28a, the rolled material M can be supported horizontally.

One end of a canvas 3 having the same width as the sheet-like material S is fixed to the connecting member 25, and the other end is fixed to the connecting member 26. Note that the length between the connecting member 25 and the connecting member 26 of the canvas 3 is equal to
The length of the canvas 3 is such that the upper surface of the canvas 3 comes into contact with a part of the outer circumferential surface of the sheet-like material S when the canvas 3 is supported.

When the rolled material M is loaded on the storage stand 2 configured as described above, the weight of the rolled material M can be dispersed and supported by the cylindrical core tube 1 and the canvas 3.

Note that in this embodiment, the pillars 21, 22, 23,
At the upper end of 24 there are strut supports 21a, 22a, 23.
a, 24a, and two or more storage stands having the same structure as the present embodiment can be stacked.

Further, in this embodiment, the connecting member 25 and the connecting member 26 are both connected to the supports 21 and 23 and the support supports 2
2 and 24, however, the present invention is not limited to this, and if either one is made to have a structure in which the canvas 3 can be rolled up, the length of the canvas 3 can be freely adjusted, and the canvas can have different diameters. You can also load rolled items.

Further, in this embodiment, the canvas 3 is used as the flexible sheet, but any other flexible material such as a sheet of rubber may be used.

Furthermore, in this example, a roll of a sheet-like thermosetting molding material was described, but the present invention is not limited to this, and the present invention is also applicable to materials having physical properties similar to the thermosetting molding material, such as It can also be applied to sheet-like rolls of food.

<Effects of the Invention> As explained above, according to the present invention, a support member that supports both ends of a shaft of a flexible sheet-like roll at a predetermined height position, and a flexible sheet with both ends fixed are provided. The upper surface of the flexible sheet contacts a part of the outer peripheral surface of the sheet-like material of the roll over the entire width thereof, with both ends of the shaft of the roll being supported by the supporting members. With this structure, the weight of the rolled material can be distributed and supported between the shaft and the flexible sheet, and the amount of deformation of the rolled material can be reduced. Therefore, the thickness of the sheet-like material can be more uniform than when a conventional storage table is used.
