However, in recent years, automobile model changes have been carried out frequently, and each time the planar shape and size of the blank are changed, it is necessary to remanufacture a dedicated packing box in accordance with the change. There was a problem of growing.

In addition, the blank material is usually transported on a material table or naked for movement in the factory. However, when blank processing is outsourced, the transport distance between the blank material processing place and the storage place becomes long, and the appearance of a transport pallet for transporting the blank material appropriately has been desired.

[0003] Therefore, as a conventional technique for solving the above-mentioned problems, a pallet that can be conveyed corresponding to blank materials having a variety of planar shapes and sizes has been proposed (for example, see Patent Document 1).

In Patent Document 1, a pallet body in which a plurality of round holes 8 are formed and an article 1 is loaded, a plurality of support bars 3 that are erected on the pallet body and support the side surface of the load, and the erection A pallet is disclosed in which the insertion pins 5 that can be inserted into the round holes 8 are provided eccentrically on the lower end side of each support rod 3. ing.

According to the pallet of the present invention, it is possible to securely and easily fix loads of various plane shapes and sizes. That is, after an article is loaded on the pallet body, a support member (lower eccentric shaft portion) is inserted into the hole of the pallet body along the load, and the load is surrounded by the support member. Then, by winding the bundling member in contact with the upper eccentric shaft portion of the support member, the side surfaces of the load are supported by the support shaft portions of the plurality of support members, and the support member and the stacking material are supported on the pallet body. Things are fixed. As a result, when the support member and the load are fixed by the binding member, the phase (vector) of the tightening force of the binding member applied to each support member in the peripheral direction of the load (vector) and the reaction applied to each support member are counteracted. The phase (vector) of the load in the peripheral direction is shifted, and a rotational force around the tightening direction is generated in each support member, and the side surface of the load is firmly pressed by the support shaft portion of each support member. . As a result, the minimum necessary (base Using a single binding member, it is possible to reliably and easily fix loads of various plane shapes and sizes. Further, when the support members are erected on the pallet body, there is almost no need to adjust the pressing force of the load by manually rotating the support members.

Further, when the support member has a movement preventing portion, it is possible to more reliably prevent the upper end force binding member of the support member (upper eccentric shaft portion) from coming off.

In addition, when the ratio (L1 / L2) of the eccentric amount (L1) of the lower eccentric shaft portion to the eccentric amount (L2) of the upper eccentric shaft portion is less than 1, tighten to the support member. The rotational force around the direction can be generated more suitably.

In addition, in the case where an insertion pin that can be inserted into the hole is provided on a side surface of the stacking support member, a plurality of stacking support members standing on the pallet body are provided. With the holding member, other pallets can be stacked and supported to improve transport efficiency and storage space efficiency. In addition, each pallet support member can also be pulled out from the pallet body, and the insertion pins of the pallet support member can be inserted into the holes in the pallet body, so that the pallet support member can be positioned horizontally on the pallet body.匕匕 can be planned.

In addition, when a plurality of mounting members are further provided, and at least one mounting member is detachably positioned on the pallet body by positioning pins inserted into the holes, the mounting members are not connected to each other. The space between them can be used to load and unload items on the pallet body. In addition, the mounting position of the mounting member with respect to the pallet body can be easily adjusted, so that it is possible to deal with a wider variety of planar shapes and sizes.

In addition, in the case where the pallet main body is provided with a plurality of display portions that indicate attachment positions of the mounting member, which are determined in advance corresponding to shapes and sizes of a plurality of types of articles, Can be adjusted more easily and quickly.

Further, when the article is a plate material laminate, it is possible to reliably and easily fix plate material laminates having a variety of plane shapes and sizes.

According to the load fixing method to the pallet of the present invention, first, an article is loaded on the pallet body or the placing member. Thereafter, the lower eccentric shaft portion of the support member is inserted into the hole of the pallet body along the load, and the plurality of support members surround the load. Next, the binding member Is wound while being brought into contact with the upper eccentric shaft portion of the support member, the side surfaces of the load are supported by the support shaft portions of the plurality of support members, and the load is fixed. Thus, when the supporting member and the load are fixed by the binding member, the phase (vector) of the tightening force of the binding member applied to each support member in the peripheral direction of the load (vector) and the reaction force applied to each support member. The phase (vector) of the load in the peripheral direction of the load is shifted, and a rotational force around the tightening direction is generated in each support member, and the side surface of the load is firmly pressed by the support shaft portion of each support member. As a result, it is possible to securely and easily fix loads of various planar shapes and sizes using the minimum necessary (basically one) binding member. Further, when the support members are erected on the pallet body, it is almost unnecessary to adjust the pressing force of the load by manually rotating the support members.

(See Figure 6). This is because the lower eccentric shaft portion can be rotated more smoothly with respect to the hole.

The pallet body can have a guide member having a reverse U-shaped longitudinal section into which a fork of a forklift can be inserted and guides the insertion of the fork. The guide member preferably includes a front / rear guide member extending in the front / rear direction of the pallet main body and a left / right guide member extending in the left / right direction of the pallet main body.

[0015] The "support member" is detachably installed on the pallet body in order to fix the load on the pallet and prevent the load from dropping from the pallet. It is. The support member is preferably a continuous body including a lower eccentric shaft portion, a support shaft portion, and an upper eccentric shaft portion described below in this order, or a connected body in which the respective portions are combined. This support member is usually linear like a rod.

[0016] The "support shaft" is a part that abuts the side surface of an article (load) loaded on the pallet and supports the load, and its shape, size, material, etc. are not particularly limited. . The cross-sectional shape of the support shaft portion is usually circular, but may be elliptical, polygonal or the like as long as the side surface of the article (load) can be supported. Further, the support shaft portion may be a hollow cylinder or a solid shape.

[0017] The "lower eccentric shaft portion" is provided on the lower end side of the support shaft portion so as to be eccentric with respect to the axis of the support shaft portion and can be inserted into the hole.

In the pallet P of the present embodiment, an upper eccentric shaft portion 23 that is eccentric to the opposite side of the lower eccentric shaft portion 22 is provided on the upper end side of the support shaft portion 21 to constitute the support member 20, and the pallet body Since the endless belt-like binding members 25 are wound around the upper eccentric shaft portions 23 of the plurality of support members 20 that are erected in 1 so that the plurality of support members 20 are bound, When bundling with the bundling member 25, the phase (vector) of the tightening force F1 of the bundling member 25 and the phase (vector) of the reaction force F2 are shifted in each support member 20 and rotated around the axis tightening direction. Moment M is generated, and the side surface of the load is firmly pressed by the support shaft portion 21 of each support member 20. As a result, it is possible to reliably and easily fix loads of various plane shapes and sizes using one binding member 25. Also, since each support member 20 rotates in the direction of pressing the load when bound, when each support member 20 is erected on the pallet body 1, each support member 20 is rotated manually to press the load against the load. There is almost no need to adjust. Further, the strength of the support member 20 can be reduced by using the binding member 25 (for example, the number of the support members 20 to be used is reduced or the weight is reduced).

Further, in the present embodiment, since the disk-shaped movement preventing portion 24 is provided on the upper end side of the upper eccentric shaft portion 23, it is possible to more reliably prevent the binding member 25 from escaping from the support member 20. In this embodiment, the ratio (L1ZL2) between the eccentric amount L1 of the lower eccentric shaft portion 22 and the eccentric amount L2 of the upper eccentric shaft portion 23 is set to a value less than 1 (0.5). Therefore, it is possible to more suitably generate a rotational force around the tightening direction on the support member 20.

Articles can be loaded into and unloaded from the pallet body 1 by inserting a hook or the like. Further, since the outer placement members 17d and 17e are detachably positioned on the pallet body 1 by the positioning pins 19 inserted into the holes 7a of the upper plate member 7, the placement members 17d and 17e are placed on the pallet body 1. The attachment positions of the members 17d and 17e can be easily adjusted, and can deal with a wider variety of planar shapes and sizes.

Note that the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention depending on the purpose and application. For example, in the pallet P of the above embodiment, as shown in FIG. 13, the pallet body 1 is predetermined according to the shape and size of a plurality of types of loading articles having different planar shapes and sizes. A plurality of display line portions 26 (indicated by phantom lines in the figure) for indicating the attachment positions of the mounting members 17d and 17e may be colored with different colors. As a result, the mounting positions of the mounting members 17d and 17e can be adjusted more easily and quickly in accordance with a plurality of types of loads.

Further, in the above embodiment, the support member 20 is configured so that the axis of the support shaft 21, the axis of the lower eccentric shaft 22, and the axis of the upper eccentric shaft 23 are located on one straight line. For example, as shown in FIG. 14, a straight line L3 connecting the shaft center of the support shaft portion 21 and the eccentric shaft center of the lower eccentric shaft portion 22, and the shaft center of the support shaft portion 21 and the upper eccentric shaft. The support member 20 ′ may be configured such that the straight line L4 connecting the eccentric shaft centers of the portion 23 intersects at a predetermined angle (for example, 30 degrees).

Furthermore, in the above embodiment, the support member 20 is configured so that the cross-sections of the lower eccentric shaft portion 22 and the upper eccentric shaft portion 23 are located within the projection plane of the cross-section of the support shaft portion 21. For example, as shown in FIG. 15, the lateral cross section of the lower eccentric shaft portion 22 and a part of the lateral cross section of the Z or upper eccentric shaft portion 23 protrude from the projection surface of the cross section of the support shaft portion 21.
