Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin pallet used for carrying articles and a method of manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, when transporting various articles, a method has been used in which the articles are stacked on a pallet, and the articles are lifted and carried together with the pallet using a forklift. There are various types of pallets for loading and transporting such articles. For example, there are wooden pallets, metal pallets, and synthetic resin pallets depending on the material.

[0003] Wooden pallets have drawbacks such as unstable supply due to tight wood resources, poor durability and chemical resistance, and complicated manufacturing. Metal pallets are disadvantageous in that they are expensive, heavy and easily corroded. for that reason,
In recent years, a synthetic resin pallet formed in a flat plate shape has been often used. For articles carried on pallets, in addition to box-shaped articles, generally cylindrical ones,
For example, there are rolled products such as film products and photographic paper rolls, and some of these rolled products have or do not have a shaft core protruding from an end surface.

[0004] In the case of roll-wound products, it is common to transport them from the state of manufacture to the state of lying down. As a conventional example of a pallet for transporting rolled products, horizontal beams are arranged opposite to a box-shaped frame, and bearing portions for receiving the axis of the rolled products are provided on these cross beams, and the rolled products are placed in the frame. There is a roll that is arranged in a lying state and supports both shaft cores on bearings provided on a cross beam (conventional example 1; Japanese Patent Application Laid-Open No. H5-254548). A dent in which the lower part of a rolled product fits, and an opening that penetrates vertically in the center of the dent (conventional example 2: JP-A-6-24550)
Furthermore, a curved concave portion is formed on the upper surface of the flat pallet to stably receive the peripheral surface of the rolled product, and the rolled product stored in the curved concave portion is fixed to the pallet with a rope. (Conventional example 3) is commercially available.

[0005]

However, in each of the conventional examples, the rolled product is placed on a pallet in a lying state, and the rolled product generally has an axial dimension in a radial direction. There are many relatively long structures as compared with, so there is a problem of taking up a transportation space. In this case, it is conceivable to transport the rolled product upright, but when the axis of the rolled product protrudes from the end surface, this shaft becomes an obstacle.

Further, in the conventional example 1, since the axis of the rolled product is supported by the cross-beam bearing provided with the box-shaped frame, the structure of the frame must be strengthened. Moreover, since the frame requires a height dimension, it is difficult to store the pallets in a stack when not in use.
In addition, the size of the frame must be changed according to the size (diameter and length) of the rolled product.

In the conventional example 2, since the peripheral surface of the roll-wound product is in direct contact with the dent of the pallet, and the opening is formed in the dent, dirt and scratches on the pallet are transferred to the product, or In addition, there is a problem that dirt adheres to the peripheral surface of the pallet from the opening and the commercial value of the rolled product is reduced. In addition, in order to transport rolled products of various sizes, the shape of the depression must be changed according to the size (diameter and length) of the rolled product, and multiple types of pallets are required. There is a problem that it is done. In other words, when a rolled product having a small diameter is stored in a large depression, a gap is formed between the depression and the rolled product, and the rolled product moves during transportation. Conversely, when a rolled product having a large diameter is stored in a small recess, the edge of the recess is pressed against the peripheral surface of the rolled product, and the product may be damaged.

Further, in the conventional example 3, as in the conventional example 2, since the peripheral surface of the roll-wound product directly contacts the curved concave portion, there is a problem that the product is soiled or damaged. In addition, in order to transport rolled products of various sizes, the shape of the curved concave portion must be changed according to the size of the rolled product, and a plurality of types of pallets are required. There is a point. In addition, in order to prevent the roll-wound product from moving during transportation, it is often necessary to fix the product by winding with a stretch film or a rope, which complicates the work of mounting the product on a pallet. In any case, in the conventional examples 2 and 3, the pallet is designed and manufactured after the rolled product to be placed is determined, and the pallet is dedicated to a specific roll and used for other articles. There is a big problem that you cannot.

SUMMARY OF THE INVENTION An object of the present invention is to provide a transportable member that can be transported without contaminating or damaging the transported member regardless of the type and size of the transported member. Storage of special products such as
An object of the present invention is to provide a synthetic resin pallet that can be transported, is easy to handle, and can be used for general purposes, and a method of manufacturing the same.

[0010]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a mounting surface for standing a member to be conveyed is formed on a substantially plate-shaped main body, and a mounting hole for fixing the member to be conveyed to a pallet is provided. Is formed on the mounting surface to achieve the above object. Specifically, the synthetic resin pallet of the present invention is characterized in that a mounting hole is formed on a mounting surface of a substantially plate-shaped main body. The mounting hole in the present invention is a hole into which an engaging member is inserted to engage and fix the transported member mounted on the mounting surface to the main body.

In the present invention having this configuration, when a transported member, for example, a roll-wound product is placed on a substantially plate-shaped main body, its end face is placed on the mounting surface of the main body, and an engaging member, for example, A shaft core that protrudes in advance from the end face is inserted and engaged with the mounting hole. In this state, the transported member is transported together with the pallet. However, since the engaging member is engaged with the mounting hole, the transported member is securely fixed to the pallet and does not move. Therefore, since the transported member which has been conventionally transported lying down is transported while standing upright, the transport space conventionally required can be omitted. Furthermore, when transported in a conventional lay-down state, the parts that contact the pallet do not come into contact with the pallet by standing the transported member, preventing the transported member from being damaged or soiled in relation to the pallet. it can.

In addition, since it is not necessary to form a curved concave portion or the like in accordance with the shape of the peripheral surface of the substantially cylindrical member on the mounting surface, the transported member is placed regardless of the size of the transported member. can do. Further, since the transported member is securely fixed to the pallet by the mounting holes, a rope for fixing the transported member to the pallet is not required. Since the pallets can be stacked up and down, the pallets can be made easy to handle and can also be used for general purposes as flat pallets on the surface.

Here, in the present invention, the main body includes two pallet forming members each having a plurality of girders separated from each other by a predetermined distance and having the mounting hole portion formed on at least one of them. The pallet molding member may have a structure in which the pallet molding members are adhered to each other with the spars except for the vicinity of the mounting hole. In this structure, the two pallet molding members are bonded together (for example, welded by heat or the like or bonded with an adhesive) between the girders, so that the fork difference for inserting the fork of the forklift between the adjacent girders is provided. Entrance can be formed. Therefore, pallets can be easily transported using a forklift.

Further, when the two pallet molding members are adhered to each other, adhesion traces such as welding beads are formed as a solid at the adhesion portion. At this time, if the vicinity of the mounting hole is set as the bonding target, the adhesion mark will protrude from the opening of the mounting hole in the mounting hole, but in the present invention, the vicinity of the mounting hole is formed. Since it is removed from the bonding object, the bonding margin does not protrude into the opening of the hole, and the mounting hole can be reliably formed over the two pallet forming members. Therefore, the engaging member is smoothly engaged with the mounting hole, so that the transported member is securely fixed to the pallet. The synthetic resin pallet of the present invention may be formed by integral injection molding instead of the above-mentioned adhesive type or in addition to the adhesive type.

Further, in the present invention, the four corners of the main body may be formed in a cut-off shape. With this structure, the pallet itself can be reduced in space and weight. Further, a structure in which a winding film locking projection is formed on the outer edge of the main body may be used. In this structure, a roll-wound product is wound with a rolled film (stretch film) in a state where a conveyed member such as a roll-wound product is placed on a main body provided with a protruding portion for locking a rolled film at a predetermined position. ,
The transported member can be sufficiently covered by hooking the edge of the rolled film to the rolled film locking projection to protect the transported member. Furthermore, in addition to the case where the mounting hole is a plane circular shape, a structure in which the mounting hole is formed in a plane polygon may be used. If it is made into a plane polygon, the mounting hole can be easily formed, and a cylindrical engaging member for fixing the transported member to the mounting surface, for example, a cylindrical shape protruding from the end surface of the roll wound product When the shaft cores are engaged with the mounting holes, the two are in line contact with each other, so that the engaging member can be easily inserted into the mounting holes.

In the method of manufacturing a synthetic resin pallet according to the present invention, the main body is formed of synthetic resin so that the mounting hole is not formed in order to manufacture the synthetic resin pallet. In this configuration, the main body is cut by a cutting unit to form the mounting hole. In this configuration, when molding the pallet molding member by injection molding, injection compression molding, or the like, the production device such as a mold is shared with the conventional production device so that the mounting hole is not formed. Can be. Furthermore, that no weld line of molten resin is formed,
There are also advantages such as no limitation on the supply of the molten resin. Moreover,
Since the main body is formed of a synthetic resin, the mounting hole can be easily formed by cutting the main body with a cutting device such as a cutter.

The pallet molding members 3 and 5 are integrally formed by press molding, injection molding, injection compression molding, or low foam injection molding usually having an expansion ratio of 1.3 or less. In addition, the pallet forming members 3 and 5 can be simultaneously and integrally formed. At the outer edge corner of the upper pallet molding member 3 and at the four locations where the spar 2 is located below, a winding film locking projection 3A is formed to protrude outward and is formed. At the remaining four positions where the fork insertion port 6 is located, a winding film locking projection 3B is formed to protrude outward. These projecting portions 3A and 3B lock the edges of the wound film 40 when the wound film (stretch film) 40 is wound in a state where the roll wound product 30 is placed on the main body 10. (See FIG. 1), and the upper surface thereof is formed in a substantially columnar shape coinciding with the upper surface of the pallet molding member 3.

The girders 2 arranged on both sides of the pallet forming members 3 and 5 are formed in an elongated box shape by combining a plurality of ribs 8. The spar 2 arranged at the center of the pallet molding members 3 and 5 is formed in a flat box shape by combining a plurality of ribs 8, and the center thereof conforms to the shape of the mounting holes 1 </ b> B and 4 </ b> B. The ribs 8A are arranged in a plane regular octagon, and the ribs 8 are arranged in a plane regular octagon along the outside of the rib 8A. The pallet molding members 3 and 5 are bonded and fixed to each other at the tips of ribs 8 constituting the spar 2. The bonding between the ribs 8 of the spar 2 is generally performed by heat welding, but other methods such as an adhesive may be used. Note that reinforcing ribs 9 may be provided in the vicinity of the fork insertion ports 6 of the plate materials 1 and 4 as necessary (see FIGS. 2 and 3).

The mounting holes 1B, 4 of the synthetic resin pallet
The detailed structure near B is shown in FIGS.
FIG. 5 is a longitudinal sectional view, and FIG. 6 is a plan view. In these figures, the ribs 8 arranged near the mounting holes 1B and 4B in each of the pallet molding members 3 and 5 are shown.
A has a lower height dimension than the other ribs 8, and
When the pallet forming members 3 and 5 are overlapped, a gap S is formed between the ribs 8A. Therefore, the ribs 8A having the gap S therebetween are not bonded to each other.

In each of the pallet molding members 3, 5, a rib 8
Ribs 8 arranged in a plane octagon along the outside of A
Has a higher height dimension than the rib 8A, like the other ribs 8, and thus the tip ends thereof are bonded to each other. A weld bead (adhesion mark) 8B is formed in the bonded portion. The mounting holes 1B and 4B are configured such that the center of each side thereof contacts the peripheral surface of the shaft core 32 of the rolled product 30 at eight locations.

Next, a method for manufacturing a synthetic resin pallet according to the present embodiment will be described with reference to FIG. FIG.
Here, the illustration is simplified for easy understanding of the contents. First, as shown in FIG. 7A, the pallet molding members 3 and 5 are molded by injection molding, press molding, or injection compression molding. Each of the pallet molding members 3 and 5 is manufactured in a state where the beam 2 composed of the ribs 8 and 8A is attached to the plate materials 1 and 4. At this time, the plate materials 1 and 4 are formed so that the mounting holes 1B and 4B are not formed.
The octagonal portions 1C and 4C defined by are formed so that the peripheral edge is thinner than the central portion (FIG. 5).
reference).

Next, as shown in FIG. 7B, the central portions of the plates 1 and 4 of the pallet molding members 3 and 5, that is, the thin portions of the regular octagonal portions 1C and 4C defined by the ribs 8A. Is cut by the cutter 20 or another cutting device to form the mounting holes 1B and 4B, respectively. Then, FIG. 7 (C)
As shown in FIG. 1, the main body 10 is manufactured by bonding the beams 2 of the pallet molding members 3 and 5 to each other. The rolled product 30 is placed upright on the synthetic resin pallet thus manufactured. That is, the cylindrical shaft core 32 as the engagement member
Are inserted into the mounting holes 1B and 4B, and the end surface of the columnar member 31 on the side where the shaft core 32 is located is mounted on the mounting surface 1A of the main body 10. Thereby, the rolled product 30 is securely fixed to the pallet, and does not move during transportation.

Therefore, according to the present embodiment, the mounting holes 1B and 4B are formed in the mounting surfaces 1A and 4A of the substantially plate-shaped main body 10, so that the rolled product 3 conventionally transported lying down is transported.
0 can be transported while standing on a synthetic resin pallet, and the transport space conventionally required can be omitted. Furthermore, the peripheral surface of the cylindrical member 31 of the rolled product 30 that has been in contact with the synthetic resin pallet when the product is conventionally laid down is no longer in contact with the synthetic resin pallet by setting the rolled product 30 upright. Therefore, it is possible to prevent the rolled product 30 from being damaged or soiled in relation to the synthetic resin pallet.

Moreover, since it is not necessary to form a curved concave portion or the like corresponding to the peripheral shape of the rolled product 30 on the mounting surfaces 1B and 4B of the main body 10, the size of the columnar member 31, that is, Regardless of the diameter or the length in the axial direction, the roll-wound product 30 can be placed. Further, since the rolled product 30 is securely fixed to the synthetic resin pallet by the mounting holes 1B and 4B, a rope for fixing the rolled product 30 to the pallet becomes unnecessary. Moreover, since the main body 10 is substantially flat, a plurality of synthetic resin pallets can be vertically stacked when not in use, so that the synthetic resin pallets can be easily handled.

In the present embodiment, the main body 10 includes two pallet forming members 3 and 5 each having a plurality of girders 2 spaced apart from each other by a predetermined distance and having mounting holes 1B and 4B formed therein. Equipped with these pallet molding members 3,
Since the girders 5 are bonded to each other, the fork insertion port 6 for inserting a fork of a forklift can be formed between adjacent girders. Therefore, pallets can be easily transported using a forklift.

In addition, when the pallet molding members 3 and 5 bond the girders 2, the ribs 8A near the mounting holes 1B and 4B are removed, so that the mounting holes 1B and 4B
And the roll-wound product 30 can be securely fixed to the synthetic resin pallet. That is, when bonding the girders 2 of the two pallet molding members 3 and 5,
A weld bead 8B is formed as a lump at the bonding portion between the ribs 8, and the ribs 8 near the mounting holes 1B and 4B are formed.
Since the gaps A are formed so that they cannot be bonded to each other, no weld bead is formed between the ribs 8A.

Therefore, the mounting holes 1B, 4B are formed continuously straight up and down, so that the mounting holes 1B, 4B are reliably formed over the two pallet molding members 3, 5. can do. Therefore, the mounting holes 1B, 4
The cylindrical shaft core 32 of the rolled product 30 is smoothly engaged with B, and the rolled product 30 is securely fixed to the synthetic resin pallet. In addition, the mounting hole 1
Even if the ribs 8A in the vicinity of B and 4B are not bonded to each other, the ribs 8 are arranged in a regular octagon outside the ribs 8A similarly to the ribs 8A. , 4B can be prevented from decreasing.

Further, since the four corners of the main body 10 are cut off to form a flat octagon, the space and weight of the synthetic resin pallet itself can be reduced, and the transport by the rolled film 40 can be achieved. The coating of the member 30 is also facilitated. Furthermore, the mounting holes 1B, 4B
Is formed in a plane octagon, so that the mounting hole 1B,
4B can be easily formed. Further, since the rolled film locking projections 3A and 3B are formed on the pallet molding member 3 of the main body 10, the wound film 40 is caught by these projections 3A and 3B, and positioning is easy and firm. And the roll-wound product 30. Moreover,
The end face of the columnar member 31 of the rolled product 30 is placed on the mounting surface 1
A is fixed to the mounting hole 1B,
When engaging with 4B, they both come into line contact at eight places,
The work of inserting and engaging the shaft core 32 into the mounting holes 1B and 4B can be easily performed. When only one side is used as the pallet, the mounting hole 4B is not particularly necessary, and in this case, the step of cutting the hole opening can be omitted.

In the method of manufacturing a synthetic resin pallet according to the present embodiment, the main body 10 is molded from synthetic resin so that the mounting holes 1B and 4B are not formed. Since the mounting holes 1B and 4B are formed by cutting with another cutting means, the mounting holes 1B are formed when the pallet molding members 3 and 5 are formed by injection molding, injection compression molding, press molding or the like. , 4B can be formed without sharing a manufacturing apparatus such as a mold with a conventional manufacturing apparatus. Further, no weld line is formed due to the flow of the molten resin, and the strength and appearance are excellent. Moreover, since the main body 10 is formed of a synthetic resin, the mounting holes 1B and 4B can be easily formed by cutting the main body 10 with the cutter 20 or another cutting device.

The present invention is not limited to the above-described embodiment, but includes modifications and improvements as long as the object of the present invention can be achieved. For example, in the present invention, the two pallet molding members 3 and 5 may be formed by integral injection molding without bonding. Further, in the present invention, a structure in which a closing member for closing the mounting holes 1B and 4B may be detachably provided in the main body 10 may be used. With this structure, when a roll-wound product without a shaft core is placed, dirt does not adhere to the product through the placement holes 1B and 4B, so this is optimal. Further, in the present invention,
The main body 10 includes a spacer member having a second hole for accommodating a shaft core having a diameter smaller than the axis 32 for accommodating the mounting holes 1B and 4B and closing the mounting holes 1B and 4B. 10
It may be a structure that is provided detachably on the vehicle. In this structure, a plurality of types of roll-wound products having different diameters of the shaft core can be transported using the same synthetic resin pallet by using the spacer member.

In the above-described embodiment, the transported member is the roll-wound product 30. However, in the present invention, the type of the transported member is not limited. For example, a tire or a hollow cylindrical member other than a tire may be used. It may be. When the transported member is a tire, one or more stacked tires are placed on the main body 10 such that the end faces thereof are placed on the placement surfaces 1A and 4A, and a rod-shaped member for fixing the tire is provided. The engaging member is inserted and engaged with the mounting holes 1B and 4B through the hole of the tire. Further, in the above-described embodiment, the main body 10 is constituted by the two pallet forming members 3 and 5. However, in the present invention, each of the pallet forming members 3 and 5 is divided into a plurality, and the main body is formed from three or more pallet forming members. It may be composed,
Alternatively, the main body may be composed of one plate-shaped member.

The synthetic resin pallet of the present invention may be a four-sided pallet. In the above-described embodiment, the pallet is a double-sided pallet having both sides 1A and 4A of the main body 10 as a mounting surface. However, in the present invention, the pallet may be a single-sided pallet having one of the main bodies 10 as a mounting surface. Good. In the case of a single-sided pallet, only one mounting hole 1B, 4B may be formed. Furthermore, although the four corners of the main body 10 are cut off, the main body 10 may be formed into a rectangular shape without cutting off, or may be formed into a circular shape in accordance with the end face shape of the rolled product 30.

The shape of the mounting holes 1B and 4B is not limited to a flat regular octagon, but may be a rolled product 3.
The shape may be a circle in conformity with the zero axis 32, or a polygon other than the octagon, for example, a triangle or a quadrangle. When manufacturing a synthetic resin pallet, the mounting holes 1B, 4B
May be cut by the cutter 20. Further, other than the cutter 20, other means such as a laser device may be used as a cutting device for forming the mounting holes 1B and 4B.

Further, the projecting portions 3A for locking the wound film,
It is not always necessary to provide 3B. Even if it is provided, it is not necessary to provide it at all corners of the pallet molding member 3 as in the above-described embodiment. For example, in the above-described embodiment, the location where the rolled film locking projection 3B is provided is a corner formed by forming the fork insertion port 6 below, so that the rolled film locking projection 3B is provided. Only 3A may be provided and the wound film locking projection 3B may be omitted.

According to the present invention, since the mounting hole is formed in the mounting surface of the substantially plate-shaped main body, the transported member which has been conventionally laid and transported is transported while standing on the pallet. As a result, the conventionally required transport space can be omitted. Furthermore, when transported in a conventional lay-down state, the parts that contact the pallet do not come into contact with the pallet by standing the transported member, preventing the transported member from being damaged or soiled in relation to the pallet. it can. In addition, since it is not necessary to form a curved concave portion or the like in accordance with the peripheral surface shape of the substantially cylindrical member on the mounting surface, it is possible to mount the transported member regardless of the size of the transported member. It can be used as a flat pallet. Further, since the transported member is securely fixed to the pallet by the mounting holes, a rope for fixing the transported member to the pallet is not required. Since the pallets can be stacked vertically, the pallets can be made easy to handle.
