Description

  The present invention relates to a roll holding jig, and more particularly to a jig for holding and transporting a roll.

For example, a sheet made of polyolefin resin is used as various battery separators such as lithium ion secondary batteries because it is excellent in organic solvent resistance and electronic insulation.
Such a sheet is normally configured as a wound body (mother roll) wound around a cylindrical support tube (core). In shipping, a wide sheet is cut into a desired width before shipping. In the case of a battery separator, since the battery has various dimensions, the sheet is cut (slit) into a width corresponding to the dimensions of the battery, and the cut sheet is wound around a core and shipped as a slit roll (Patent Document 1). reference).

  For example, when a slit roll is conveyed on a ball conveyor, it is necessary to protect the sheet from being damaged and contaminated by dust due to the property required as a battery separator. Therefore, the slit roll is accommodated in a storage box or the like and conveyed (see Patent Document 2).

  However, when the slit roll is accommodated in the storage box and transported, an impact or the like may be given to the storage box. Due to this impact, the storage box may be deformed, which may cause scratches and dirt on the slit roll.

  Furthermore, when an insertion tube such as a pipe is inserted through the core of the slit roll, it is difficult to store the roll in the storage box together with the insertion tube or to remove the insertion tube from the roll in the storage box. Transporting can be difficult.

  The present invention has been made in view of the above-described conventional situation, and an object thereof is to provide a roll holding jig that can be transported while suppressing damage and contamination of the slit roll.

[1] A roll holding jig for holding one or more rolls in a state of being arranged in the roll width direction,
A tray body made of foam,
A storage recess formed in the tray body, having a substantially semi-cylindrical shape matched to the shape of the roll, and storing the roll;
A notch portion formed so as to be opposed to both ends in the longitudinal direction of the storage recess,
The notch is formed so that the insertion tube can be extracted from the roll through the notch after the roll into which the insertion tube has been inserted is stored in the storage recess. A roll holding jig.

[3] The roll holding jig according to [1] or [2], further comprising a cushioning material arranged to cover at least a part of the storage recess.
[4] The roll holding jig according to [3], wherein the cushioning material is a bubble cushioning material.

  In the roll holding jig of the present invention, since the tray main body is made of a foam, it is possible to prevent damage to the roll and contamination by preventing the roll from impact during transport of the roll. Further, since the substantially semi-cylindrical shape of the storage recess matches the shape of the roll, it is possible to transport the roll while suppressing damage and contamination of the roll. Furthermore, since the insertion tube can be easily extracted from the roll through the notch, the handleability of the roll is improved, and the roll can be easily held and transported.

Fig.1 (a) is a perspective view which shows one structural example of the roll holding jig of this invention, and FIG.1 (b) is a front view of the structural example. It is a perspective view which shows the state which hold | maintained the roll to the roll holding jig of this invention. It is a front view which shows another structural example of the roll holding jig of this invention.

Embodiments of the present invention will be described below with reference to the drawings.
Fig.1 (a) is a perspective view which shows one structural example of the roll holding jig of this invention, and FIG.1 (b) is a front view of the structural example. FIG. 2 shows a state in which a plurality of rolls are stored side by side in the roll width direction in the roll holding jig shown in FIG.
The roll holding jig 1 is used to hold one or a plurality of rolls 20 in a state where they are arranged in the width direction of the rolls 20. The roll 20 can be transported or a label can be attached to the roll 20 on a conveyor such as a ball conveyor, for example, while the roll 20 is housed in the roll holding jig 1.
The roll holding jig 1 includes a tray main body 10 made of foam, a storage semi-cylindrical shape that is formed on the tray main body 10 and matches the shape of the roll 20, and stores the roll 20. A notch 12 formed so as to be opposed to both ends in the longitudinal direction of the recess 11. The notch 12 stores the roll 20 through which the insertion tube is inserted in the storage recess 11, and then the notch 12, the insertion tube is formed so that it can be extracted from the roll 20.

The tray body 10 has a size sufficient to accommodate one or a plurality of rolls 20. In the roll holding jig 1 shown in FIGS. 1 and 2, the tray body 10 has a substantially box shape having a longitudinal direction, a width direction, and a depth direction so as to conform to the shape of the roll 20.
The tray body 10 is made of a foamed material such as foamed plastic. By the foam, the roll can be prevented from being impacted when the roll is transported. The foamed plastic may be polyurethane; polystyrene; polyolefin, such as polyethylene or polypropylene, and is preferably a polyolefin from the viewpoint of impact resistance or non-invasiveness to rolls.

The storage recess 11 formed in the tray body 10 has a substantially semi-cylindrical shape that matches the shape of the roll 20. The roll 20 is stored in the storage recess 11. The longitudinal direction of the storage recess 11 corresponds to the longitudinal direction of the tray body 10.
Since the roll section is substantially circular, the storage recess 11 having a substantially semi-cylindrical shape can store one or a plurality of rolls 20 in a state where the storage recess 11 and the roll outer shape are adapted. Further, the roll 20 can be transported or rotated while the roll 20 is stored in the storage recess 11.

At least one pair of notches 12 are formed at both ends in the longitudinal direction of the storage recess 11 so as to face each other. The notch 12 is formed so that the insertion tube can be extracted from the roll 20 through the notch 12 after the roll 20 having the insertion tube inserted therein is accommodated in the accommodation recess 11.
The insertion tube is a tubular member through which the roll 20 or the roll core 21 is inserted. The longitudinal direction of the insertion tube corresponds to the longitudinal direction of the storage recess 11 and the width direction of the roll 20. The insertion tube can be formed of metal, plastic, paper, wood or the like. Further, a rod may be used instead of the insertion tube, or a rod or an additional insertion tube may be inserted into the insertion tube.
Since the insertion tube protruding from the width direction end of the roll 20 is fitted into the notch 12, the roll 20 can be easily stored in the storage recess 11 even if the insertion tube is inserted through the roll 20. .
Further, the pair of cutout portions 12 are opposed to each other at both ends in the longitudinal direction of the storage recess 11, and therefore receive and fix the insertion tubes protruding from both ends in the width direction of the roll 20. In that case, not only the positioning of the roll 20 with respect to the storage recess 11 but also the insertion tube can be taken into and out of the roll 20 through the pair of notches 12.
In the case where the insertion tube passes through the plurality of rolls 20 and communicates with the plurality of rolls 20, after the plurality of rolls 20 are stored in the storage recess 11 together with the insertion tube, the plurality of insertion tubes are inserted through the pair of cutout portions 12. By extracting from the roll 20, the plurality of rolls 20 are held by the roll holding jig 1 as shown in FIG. 2.

It is also preferable that a cushioning material is disposed so as to cover at least a part of the storage recess 11. The cushioning material may cover part or all of the surface of the storage recess 11. The cushioning material may extend from the storage recess 11 to the end of the tray body 10 in the width direction.
FIG. 3 shows a state in which the cushioning material 13 is arranged so as to cover the storage recess 11 and both ends of the tray body 10 in the width direction. The buffer material 13 relieves direct contact between the storage recess 11 and the roll 20 and suppresses damage or contamination of the roll 20.
The cushioning material 13 may be formed of any material depending on the mass or size of the roll 20, but from the viewpoint of cushioning properties, followability to the roll shape, and handling properties, a bubble cushioning material such as an air cap (registered trademark) is used. And the like.

  As described above, in the roll holding jig 1, since the tray main body 10 is made of a foam, it is possible to prevent the roll 20 from being impacted and to prevent damage and contamination of the roll 20 when the roll 20 is transported. . Moreover, since the substantially semi-cylindrical shape of the storage recess 11 matches the shape of the roll 20, it is possible to transport the roll 20 while suppressing damage and contamination of the roll 20. Furthermore, since the insertion tube can be easily extracted from the roll 20 through the notch 12, the handleability of the roll 20 is improved, and the roll can be easily held and transported.

  As mentioned above, although embodiment of this invention has been described, this invention is not limited to this, It can change suitably in the range which does not deviate from the meaning of invention.

  Since the roll holding jig according to the present invention can be transported while suppressing damage and contamination of the slit roll, it can be widely used as a roll holding jig for a separator.
