Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention guides a packing material such as a stack of cut plates into a rectangular parallelepiped packing object with a packing material such as a heat-shrinkable resin film, which guides the packing material to the side surface of the packing object. Related to packaging jigs.

[0002]

2. Description of the Related Art Generally, in order to wrap a side surface of a rectangular parallelepiped object such as a stack of cut plates (hereinafter referred to as a cut plate lot) with a packaging material such as a heat-shrinkable resin film, a film formed in a ring shape in advance is used. A method in which an operator holds a part that hits a corner portion of the cutting plate lot and pulls down along the side surface of the cutting plate lot, or a film is formed into an annular shape by a mechanical force as shown in JP-A-5-229529. While wrapping methods are known.

In the former method, that is, in the method of pulling down a film formed in a ring shape in advance along the side surface of the cutting plate lot, not only is the film caught on the corner portion of the upper surface of the cutting plate lot, it is difficult to pull down the film, but also the film tears when pulling down. There were problems such as being lost. In the case of the latter method, the side surface of the cut sheet lot is packed while the objects to be packed are transferred by a transfer means such as a conveyor, so that a large space for the transfer device is required.

This will be described with reference to FIG. This figure is a perspective view schematically showing the packing process. 1 is an object to be packed, 21 and 22 are packaging materials (film), 5 is a conveyor for transferring the object to be packaged, 6 is a packaging material 21 and 22 left and right. It is a heat conduction member with a guide that is pressed from the to-be-packaged body 1. The object to be packed 1 is transferred by the conveyor 5, the packaging materials 21 and 22 which are heat-welded are arranged in a direction transverse to the traveling direction, and the front surface of the object to be packed 1 is brought into contact with the packaging materials 21 and 22. In this state, the object to be packed 1 is transferred and the side surfaces thereof are surrounded by the wrapping materials 21 and 22, and after enclosing, the wrapping materials 21 and 22 on both sides are brought into contact with each other by the heat conducting member 6 with a guide and heat-welded at two locations. The intermediate part is cut and the side surface of the packaged object 1 excluding the bottom surface and the top surface is surrounded and packed.

As described above, this method requires a transfer device such as a conveyor and a mechanical device such as a heat-conducting member with a guide, which requires a large space and causes a large capital investment.

[0006]

DISCLOSURE OF THE INVENTION The present invention solves such a problem and is easy to work without requiring a particularly large space or a mechanical device, and can be applied to an object to be packaged without damaging the packaging material. It is an object to provide a packaging jig for guiding.

[0007]

SUMMARY OF THE INVENTION According to the present invention, a packing material having a rectangular parallelepiped shape is covered with a packing material formed in an annular shape in advance to pack the four side surfaces of the packing object. A guide for the packing, the lower end of which can contact the four corners of the upper surface of the article to be packed, the upper part of which is inclined inward, and the outer surface of which guides the packaging material; It is characterized by comprising two connecting members that are connected to the inner surface of the guide member at each tip and connect in a cross shape. More preferably, the connecting members are extendable / contractible in the length direction and near the center thereof. The packing jig is joined by a joining means so that the crossing angle can be changed.

[0008]

According to the present invention, four corner guides of a packing jig are arranged at the four corners of the upper surface of a lot of a cutting board, and a film preliminarily formed into an annular shape is formed into the four corners. When sliding the guide along the outer surface of the corner guide of the book and guiding it to the side of the packaged item, the work is easy and there is no risk of damage to the film, and the length and crossing angle of the connecting member can be adjusted. Can easily respond to changes in the size of the cutting board lot.

Embodiments of the present invention will be described with reference to the drawings. Figure 1
1 is a perspective view showing the concept of the packing work according to the present invention, 1 is a cutting plate lot which is a rectangular parallelepiped to be packed, 2 is a packing material made of a heat-shrinkable resin film molded in an annular shape, and 3 is A packing jig 4 for guiding the packaging material 2 to the side surface of the packaged object 1 is a skid on which the packaged object 1 is placed.

FIG. 2 is a perspective view showing a state in which the packing jig 3 is placed on the upper surface of the object to be packed 1. The lower end of the packing jig 3 can contact four corners of the upper surface of the packaged object 1, the upper part is inclined inward, and the four guide members 31 for guiding the packaging material on the outer surface are provided. Two connecting members 32 which are connected to the inner surface of the guide member at the tip end thereof and are connected in a cross shape.
Consists of. Since the connecting member 32 is connected to the inner surface of the guide member 31 slightly above the lower end of the guide member 31, the packaging jig 3 is placed with the connecting member 32 contacting the upper surface of the cutting plate lot. It Since the upper part of each guide member 31 is inclined inward, if the packaging material 2 made of a heat-shrinkable resin film formed in an annular shape is put on the packaging jig 3 and pulled down, the packaging material 2 becomes very natural. It is guided to the side surface of the packaged object 1.

Although the guide member 31 is L-shaped in cross section in these drawings, it may be C-shaped or the like with roundness. Each guide member 31 of the packing jig 3 may be fixed according to the size of the cutting plate, but it is rare that the size of the cutting plate is constant in the cutting plate processing equipment, and several kinds of cutting plates are used. It is common to have a board. The packing jig 3 may be replaced with a packing jig 3 suitable for each size each time, but it is more preferable that the packing jig 3 can be changed in size in accordance with the size of the cut plate.

An example of a packaging jig whose dimensions can be changed is shown in FIGS.
Will be described. FIG. 3 is a cross-sectional view of the packaging jig cut a little above the connecting member, and FIG. 4 is a perspective view showing the vicinity of the center of the connecting member 32 in a disassembled state. That is, this connecting member is provided with a long hole in the longitudinal direction in the vicinity of the center as shown in FIG. It is desirable to appropriately provide the claws 32a and the like so that they are not bent so that they are fitted to each other. Then, as shown in FIG. 3, the two connecting members 32 are connected by a connecting means 33 such as a bolt or a pin near the center thereof so that the crossing angle can be changed. The coupling means 33 can also serve as fixing the expansion and contraction in the lengthwise direction.

Since the packing jig 3 with the loosened coupling means 33 is placed on the cutting board lot 1 and the length and angle of the connecting member 32 are adjusted to the cutting board lot 1, the coupling means 33 can be tightened. It is extremely easy to adjust the length and angle to the cutting board. When packing a lot of cut boards using this packing jig, the number of film tears, which was about 5 lots out of 200 lots in the past, was reduced to 1 lot, and the work was made easier. The time required for work was reduced from 30 seconds to 18 seconds, and a 40% improvement in efficiency was confirmed.

EFFECTS OF THE INVENTION According to the present invention, the efficiency of the work of covering the rectangular parallelepiped strip with the packaging material is improved and the packaging material is prevented from being damaged.
