DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for storing a bobbin or the like in a box or collectively wrapping and packing a plastic bag or a stretch film and, if necessary, a PP (polypropylene) band. The present invention relates to a holder for a bobbin or the like for fixing and holding a bobbin or the like in a box or a collective package when transporting the same, and a holding plate for a bobbin or the like using the same.

[0002]

2. Description of the Related Art Conventionally, various holders of this type have been proposed, and one of the representative ones is a bobbin storage socket described in Japanese Utility Model Publication No. 46-13513. As shown in FIG. 9, this socket has a flange 2 provided at a lower portion of a cylindrical socket body 1 and a projection 4 provided on an outer peripheral surface 3 of the socket body 1.
The socket body 1 is fitted into a hole provided in the base plate 5 such as corrugated paper, and each end of the core 7 of the bobbin 6 is inserted and gripped into a portion of the socket body 1 protruding from the base plate 5.

[0003]

However, in a socket having such a structure, as shown in FIG. 9, the socket must be applied to both ends of the core 7 of the bobbin 6, so that a large number of bobbins are required. For a company that packs and transports 6, it has been an important issue to reduce the number of sockets as much as possible to reduce costs.

As shown in FIG. 10, when a plurality of base plates 5 with sockets are stacked and stored or transported, the height of the socket itself is high and the upper and lower sockets are connected to each other. Because of the collision, the overall height is not reduced, which requires a large space and a large space, resulting in poor storage and transportation efficiency.

On the other hand, when the socket is removed from the base plate 5 to store and transport the socket, the removal of the socket due to the projections 4 is troublesome, and the height of the socket itself is high and one socket is connected to another socket. Since the socket is not formed in a shape that can be inserted into the hollow portion of the socket, there is a problem that the removed socket is bulky and also difficult to handle.

An object of the present invention is to improve the conventional socket so as to eliminate the above-mentioned disadvantages.

[0007]

In order to achieve the above object, a holding tool for a bobbin or the like according to the first invention is provided with a short cylinder in the middle of the lower surface of a flat flange extending outward from the lower end of a cap cylinder. Part is formed, the cap tube portion, the disk-shaped top and the short tubular body are connected via a taper or roundness, a plurality of ridges on the outer periphery of the body The short cylindrical portion has a double wall structure having a U-shaped cross section, and the inner cylindrical portion and the outer cylindrical portion are connected by a plurality of radial reinforcing ribs. And the lower end of the inner cylinder portion is tapered or rounded. Also,
A holding plate for a bobbin or the like according to a second aspect of the present invention is formed by fitting a body of a cap tube portion of the holding tool for a bobbin or the like to a fixing hole provided in a fixing plate.

[0008]

In the holder having the above-mentioned structure, the cap tube is strongly pushed into the fixing hole of the fixing plate to bring the flange into contact with the fixing plate.
At this time, the body of the cap tube portion is tightened by the elastic force of the material of the fixing plate because the ridge on the outer periphery locally expands the inner peripheral wall of the fixing hole, and is securely fitted in the fixing hole. You. Further, by forming an occlusal hole near the flange portion of the ridge of the cap tube portion, the holder is engaged with the occlusal hole, and is more firmly fitted to the fixing plate.

Thus, according to the holding plate on which the holding tool of the present invention is fitted, two bobbins and the like can be held by one holding tool. That is, while inserting the outer periphery of the cap tube part of the holder into the hollow hole of the core part such as one bobbin,
The two bobbins and the like are held by inserting the outer periphery of the core such as the other bobbin into the hollow hole of the short cylindrical portion of the holder.

When storing and transporting a plurality of the holding plates, it is not necessary to remove the holding members from the fixing plate, and to lower the overall height by stacking the upper and lower holding members in the axial direction. Thereby, the space required for storage and transportation can be reduced. To remove the holding tool from the fixing plate, it is only necessary to push the cap tube of the holding tool strongly in the direction of the flange against the resistance of the ridge, which is simple. Removed holders can be stacked with multiple holders by inserting the cap tube part of one holder into the hollow part of the other holder, so large space is not required for storage and transportation, and handling is easy. is there.

When the detached holder is to be fitted to the fixing plate again for reuse, it is preferable that the position of the ridge be slightly shifted from the position at the time of the previous fitting. Thus, the fixing plate can be used repeatedly without making the fitting of the holder uncertain.
