Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pallet for transportation.

[0002]

[Prior art]

 In a conventional transport pallet, as described in Japanese Utility Model Publication No. 52-57578, a plurality of ribs are juxtaposed at predetermined intervals between upper and lower flat plates, and the upper and lower flat plates and the ribs are integrally combined. It is configured to do. Then, the lower flat plate is placed on the transport surface of the transport device, the upper flat plate serves as a load supporting surface, and the opening surrounded by the upper and lower flat plates and the rib serves as a fork of the forklift pawl.

[0003]

[Problems to be solved by the device]

 However, the conventional technique has the following problems. The horizontal width (distance between adjacent ribs) and vertical width (rib height) of the forklift pawl insertion port are too large for the cross-sectional dimensions of the forklift pawl. Since the width is too large, the center of the pair of forklift pawls inserted into the insertion slot is displaced from the center of gravity of the entire pallet supporting the load, impairing the lift-up stability. Also, since the vertical width is too large, when an unbalanced load is applied to the pallet, the pallet tilts up and down by the amount of play of the forklift pawl with respect to the upper and lower surfaces of the loading slot, impairing the lift-up stability.

The lower surface of the pallet placed on the transfer surface of the transfer device is formed of a flat plate, and no space is created between the lower surface of the pallet and the transfer surface of the transfer device. For this reason, it is not possible to install functional parts that project onto the transfer surface of the transfer device, such as sensor dogs for transfer and positioning control.

An object of the present invention is to ensure the stability of lift-up by a forklift and to install functional parts such as sensor dogs on the transfer surface of the transfer device.

[0006]

[Means for Solving the Problems]

 The present invention is a lower pipe consisting of a square pipe that can be placed on the conveying surface of a conveying device, and is assembled on the lower pipe by centering to form a forklift pawl insertion port and support a load. And a pair of upper pipes made of square pipes.

[0007]

[Action]

 Since the upper pipe forming the insertion port of the forklift pawl is made of a square pipe, the horizontal width and the vertical width of the insertion port do not become excessively large with respect to the sectional size of the forklift pawl, and conform to the sectional size. The vertical and horizontal clearances can be reduced. As a result, the center of the pair of forklift pawls inserted into the insertion port can be prevented from laterally shifting with respect to the center of gravity of the entire pallet supporting the load. Further, the play of the forklift pawls with respect to the upper and lower surfaces of the insertion port is small, and it is possible to prevent the pallet from tilting vertically due to an unbalanced load. Therefore, stable lift-up can be ensured.

As a result of the lower surface of the pallet placed on the transfer surface of the transfer device being composed of a lower pipe made of a square pipe, a space can be formed between the lower surface of the pallet and the transfer surface of the transfer device. . Therefore, functional parts such as sensor dogs can be installed on the carrying surface of the carrying device, and the carrying and positioning controllability can be improved.

【Example】

 1 is a schematic diagram showing a first embodiment, FIG. 2 is a schematic diagram showing a second embodiment, and FIG. 3 is a schematic diagram showing a third embodiment.

First Embodiment (see FIG. 1) In FIG. 1, 1 is a chain conveyor, 2 is a load, and 10 is a pallet. The pallet 10 is composed of two lower pipes 11 arranged in parallel in a sled shape and an upper pipe 12 arranged in parallel so as to form a pair of two sleds, which are framed at right angles by welding or the like.

The lower pipe 11 is a square pipe and can be placed on the conveying surface of the conveyor 1. The lower surface area of the lower pipe 11 which is in contact with the conveying surface of the conveyor 1 is set to a minimum. Further, the interval w between the pair of lower pipes 11 may be constant without changing even if the width W of the body is changed.

The upper pipe 12 is a square pipe, and the upper pipes 12 forming a pair are assembled on the lower pipe 11 with the centers thereof distributed (see FIG. 1B). The upper pipe 12 forms a forklift claw insertion port 12A and can support the load 2.

The operation of this embodiment will be described below. Since the upper pipe 12 forming the insertion port 12A of the forklift pawl is made of a square pipe, the lateral width and the vertical width of the insertion port 12A do not become excessively large with respect to the sectional size of the forklift pawl, and the sectional size is It is possible to have a small clearance on the top, bottom, left and right to suit. As a result, it is possible to prevent the center of the pair of forklift pawls inserted into the insertion opening 12A from being laterally displaced with respect to the center of gravity of the entire pallet 10 supporting the load 2. In addition, the play of the forklift pawls with respect to the upper and lower surfaces of the insertion opening 12A becomes small, and it is possible to suppress the pallet 10 from tilting vertically due to an unbalanced load. Therefore, stable lift-up can be ensured.

As a result of the lower surface of the pallet 10 placed on the transfer surface of the chain conveyor 1 being composed of the lower pipe 11 made of a square pipe, between the lower surface of the pallet 10 and the transfer surface of the chain conveyor 1. Space can be formed. Therefore, functional parts such as sensor dogs can be installed on the transfer surface of the chain conveyor 1, and the transfer and positioning controllability can be improved.

Second Embodiment (See FIG. 2) The pallet 20 differs from the pallet 10 in that the lower pipes 11 made of four square pipes are arranged in parallel with each other. The inner two lower pipes 11A can be placed on the conveying surface of the chain conveyor 1, and the outer two lower pipes 11B can be placed on the conveying surface of the elevating roller conveyor 3. As a result, the transfer between the conveyors 1 and 3 can be smoothly performed.

(Third Embodiment) (See FIG. 3) The pallet 30 is different from the pallet 10 in that the lower pipes 11 made of four square pipes are arranged in a frame so as to form a rectangle.

In the practice of the present invention, two or more pairs of upper pipes for inserting the forklift pawls may be provided. At this time, one pair of upper pipes and the other pair of upper pipes may be (a) narrow and wide ones parallel to each other, or (b) orthogonal to each other and four-sided. It may be possible to insert from.
