Description

  The present invention relates to a roll-shaped product protector for transporting and storing a roll-shaped product obtained by winding a long product such as a film around a core, and more specifically, the width of the roll-shaped product has been changed from long to short. Even in this case, the present invention relates to a roll product protector that can be reasonably handled.

  As an example of a conventional protector for roll-shaped products, a protector for transporting and storing a roll product in which a wide strip-shaped product such as a plastic film or paper is wound around a hollow core portion, is rolled on the back side of the protector. A square substrate part that holds the end face of the product, a roll product support cylindrical part that protrudes from the center of the back surface of the substrate part so that it can be inserted into the hollow hole of the hollow core part of the roll product, and a square that projects on the back side of the substrate part. And a stacking recess provided in a square on the surface of the substrate portion so that the tip of the leg portion can be inserted, and provided in the center of each side surface of the substrate portion. 2. Description of the Related Art A protector for roll products that includes a band groove for packing and is formed of a hard synthetic resin is known (see, for example, Patent Document 1).

  According to the structure of this conventional protector for roll products, it is used by being assembled at both ends of a roll product obtained by winding a wide strip product such as a plastic film or paper around a hollow core, that is, a substrate part of a pair of protectors. The both ends of the roll product are pressed and held on the back surface of the roll product, and the cylindrical portion is inserted into the hollow hole of the hollow core portion of the roll product to support the roll product, and then provided at the center of each outer peripheral surface of the substrate portion. Two packing bands are hung in a cross shape in the band groove and tightened as a whole.

  Thus, the substrate portion prevents the belt-like product from sliding out into a bamboo shoot to the side during transportation and storage, and when the roll product is placed horizontally on the floor surface or in the packaging container, In addition to preventing the product from coming into contact with the floor surface or the bottom of the packaging container and fouling, roll products with protectors assembled can be rolled safely, without the risk of collapse. It is possible to transport and store in a stack.

  However, in the above-mentioned conventional protector for roll products, the both ends of the roll product are held and fixed by the back surfaces of the substrate portions of the pair of protectors, so the length of the hollow core portion around which the belt-shaped product is wound is set. If the width of the roll product changes short and long under the condition that it is fixed to a certain length, it will not be possible to respond quickly, and if the both ends of the roll product are held and fixed, In order to make this method possible for all roll products having different widths, it is necessary to prepare many types of protectors having different thickness dimensions of the substrate portions of the pair of protectors. As a result, these cause cost increases, and a protector must be selected in accordance with the width of the roll product, so that there is a problem that workability deteriorates.

  In view of the above problems, the present invention is rational with one type of protector even when the width of the roll-shaped product is changed to a long or short width with respect to the hollow core portion of the same length wound around the belt-shaped product. It aims at providing the protector for roll-shaped products which can respond to.

  In order to achieve the above object, according to a first aspect of the present invention (Claim 1), in a protector for a roll product obtained by winding a long product around a core, a through-hole portion is provided to be inserted through the core. It is a plate-like body, and one surface has a smooth surface that comes into contact with the end surface of the roll-shaped product, and the other surface has a fixing portion for the core, and the fixing portion is transparent when facing each other. The fixing piece A has a circular arc portion that has substantially the same diameter as the hole, and the fixing piece A is fixed at one end of the circular arc portion while the circular arc portion is fixed along the through hole portion. The roll product protector is characterized in that the piece B is connected by a hinge so that it can be opened and closed, and a stopper that can be fastened and fixed to the other end of the fixed piece B is provided at the other end.

  Claim 2 as a preferred embodiment is the roll product protector according to claim 1, characterized in that an elastic body is interposed at the joint between the fixed piece A and the fixed piece B connected by a hinge. is there.

  According to a third aspect of the present invention, there is provided the roll product protector according to any one of the first and second aspects, wherein an elastic sheet is provided on the arc portions of the fixed piece A and the fixed piece B.

Claim 4 as a preferred embodiment is the roll product protector according to any one of claims 1 to 3 , wherein an elastic sheet is provided on a smooth surface in contact with the end face of the roll product. is there.

  The roll-shaped product protector according to the present invention is a roll-shaped product protector formed by winding a long product such as a film around a core, and is a plate-like body having a through-hole portion inserted through the core. One side has a smooth surface that comes into contact with the end face of the rolled product, and the other side has a fixed part that is fixed to the core, so that a long core is wound around the same length. On the other hand, even if the width of the roll-shaped product is long or short, the smooth surface can be contacted with the end surface of the roll-shaped product and fixed at an arbitrary position on the core, so one type of protector can be used. It becomes possible to respond. As a result, the cost is greatly reduced, and the conventional work of selecting a protector in accordance with the width of the roll product is eliminated, so that the work efficiency is further improved.

According to the present embodiment, the end face of the roll-shaped product and the plate-like body 1 are in contact with each other via the elastic sheet 12, that is, the end face of the roll-shaped product is elastically and softly in contact with the protector. In this case, even if there is some attachment error, it can be brought into close contact with the roll product, and the roll product is not damaged by vibration during transportation.

Usage 1
Next, the usage pattern of the protector of the present invention will be described.
As shown in FIG. 7, a long product such as a film is wound around a core 15 to form a roll-shaped product 16. Therefore, in order to prevent this, the protector 17 is attached from both sides. That is, the smooth surface 3 of the plate-like body 1 is inserted through the center core 15 so as to come into contact with the end face of the roll-like product 16, and is fixed by the stopper 9 (see FIGS. 1, 5, and 7).

Usage 2
The usage form which used the protector of this invention together with the outer protector is demonstrated.
There are various types of long strip products such as film.For example, when the weight of the roll-shaped product 16 is large, as shown in FIG. A mold outer protector 18 can be inserted and mounted. According to this embodiment, the leg portion made of a plate-like body that supports the heavy roll-shaped product 16 is approximately twice as strong, so that load resistance as a protector is guaranteed.

  As described above, the protector for roll-shaped products of the present invention has a smooth surface brought into contact with the end surface of the roll-shaped product, even when the width of the roll-shaped product is changed. Since it can be fixed at the position, it is possible to cope with one type of protector. As a result, the cost is greatly reduced, and the conventional work of selectively using the protector in accordance with the width of the roll product is eliminated, so that the work efficiency is further improved.
