[Detailed description of the invention] <Industrial application field> This invention relates to a waste pallet for storing waste generated from workplaces, etc., such as wood chips, iron scraps, etc. This is a waste pallet on which waste is dropped.

<Prior Art> Conventionally, there is a waste pallet as shown in FIG. 5, which is a large-sized pallet whose bottom plate is opened and articles stored therein are dropped. The pallet 21 has a substantially cubic shape, and a hook member 25 for hooking a wire from a crane is welded to the center of the upper surface, and an input port 21c for inputting waste such as garbage is provided on both sides of the hook member 25. and each has a lid 22. Furthermore, a rail member 27 is vertically welded to the center of one side surface 21a, and a support member 28 that slides along the rail member 27 is disposed. On the outer surface of the support member 28, there is a hook member 2 for hooking a wire from a crane in addition to the above-mentioned wire.
8a are welded to each other, and support rods 28b connected to the bottom plate 23 are rotatably connected to both lower ends of the support member 28, respectively. Similar members are also disposed on the side surface opposite to the side surface 21a on which the support member 28 and the like are disposed. Further, the bottom plate 23 of the pallet 21 is divided at the center, that is, the line connecting the rail members 27, 27, and is arranged so as to open outward, and the support rods 28b are connected to both sides of the bottom plate 23, respectively. has been done.

In order to take out the waste stored in this pallet 21, first, a vertically movable wire installed in a crane is connected to a hook member 25 provided on the upper surface.
Separately, two wires connected to the crane are each hooked onto the hook members 28a of the support member 28 provided on the side surfaces. next,
The pallet 21 is lifted and moved to a predetermined position while keeping the wire hooked to the support member 28 on the side surface 21a under tension so that the bottom plate 23 does not open. Then, the wire hooked on the hook member 25 on the upper surface is wound up. Then, the wire hooked to the side support member 28 loosens, so the bottom plate 23
Due to the weight of the waste hanging on the bottom plate 23 and the weight of the bottom plate 23 itself, the bottom plate 23 opens outward, and the supporting member 28 moves downward along the rail member 27. Move to.

<Problem that the invention aims to solve> Conventional waste pallets have the above-mentioned structure, so a crane is usually required to remove the waste contained therein, and it is not commonly used in workplaces. This work would not have been possible with a forklift truck. Therefore, a crane must be installed to lift such waste pallets and take out the waste, which is uneconomical both in terms of space and economy.

<Means for solving the problem> This invention was developed in view of the above-mentioned problem, and is a method for removing waste stored in large waste pallets, which is commonly used in workplaces. The purpose is to provide a waste pallet that can be carried out on a forklift truck and has the following structure.

In other words, it is a box-shaped pallet for storing waste, and the bottom plate of the pallet is formed of two members so that it can be double-opened, and one end of each member of the bottom plate is attached to the lower end of each of the left and right side walls of the pallet. In the supported waste pallet, a pair of fork holding cylinders into which the forks of the forklift truck are inserted are parallel to the lower part of the front wall of the pallet and are supported through a support member.
The lower part of the fork holding cylinder projects downward from the lower end of the front wall of the pallet, and furthermore, a spring member that biases the bottom plate in the closing direction is supported pivotably on each member of the bottom plate. This is a structure arranged near one end.

<Example> Hereinafter, an example of this invention will be described based on the drawings, but various embodiments can be considered as long as they do not depart from the scope of the technical idea of this invention.

Figure 1 shows how the fork holding cylinder 5 is inserted into the waste pallet 1 (hereinafter referred to as "pallet") so that the fork 15 can be inserted.
Fig. 2 is a perspective view of the fork holding cylinder 5 with the bottom plate 3 opened perpendicular to the front wall 1a of the fork holding cylinder 5.
is a perspective view showing a state in which the pallets are placed side by side on the front wall 1a and placed on the floor.

The pallet 1 has a substantially cubic shape, and no plate-like member is disposed at the upper part, which serves as a waste inlet 1c.

Further, at the lower part of the pallet front wall 1a, there is provided a hollow rectangular parallelepiped fork 1 of the forklift truck.
A pair of fork holding cylinders 5 into which 5 can be inserted are provided. This fork holding cylinder 5 usually has a second
As shown in the figure, its wide surface 5a is arranged parallel to the pallet front wall 1a, and the lower part of the fork holding cylinder 5 is arranged to protrude from the lower end of the pallet front wall 1a. Further, a shaft 6 having a circular cross section is located below the lower end of the front wall 1a of the pallet front wall 1a of the wide outer surface 5a of the fork holding cylinder 5 by the thickness of the fork holding cylinder 5, and a shaft 6 having a circular cross section is attached to both sides 7a of the supporting member 7, which will be described later.
The fork holding cylinder 5 is fixed to the fork holding cylinder 5 so as to extend over the shaft 7a, and the fork holding cylinder 5 is rotated about this shaft 6. And, the fork holding cylinder 5 is
From the state where the pallet is stored parallel to the front wall 1a
When it is rotated 90 degrees and becomes perpendicular to the pallet front wall 1a,
The portion of the fork holding cylinder 5 that protrudes from the pallet front wall 1a comes into contact with the lower end of the pallet front wall 1a, so that it cannot be rotated any further. In this embodiment, the shaft 6 is fixed to the fork holding cylinder 5, but a substantially semi-cylindrical guide member that can guide the shaft 6 while the fork holding cylinder 5 rotates as described above is used. It can also be placed.

Additionally, a connecting rod 5 is provided above the shaft 6 when the fork holding cylinder 5 is stored so as to span the fork holding cylinder 5.
b, so that the pair of fork holding cylinders 5 can be interlocked, and can be locked and stored at one place. In this embodiment, when the fork holding cylinder 5 is stored, a locking member 9 that is elastic and has a concave portion capable of locking the connecting rod 5b is vertically projected from the front wall 1a of the pallet corresponding to the connecting rod 5b. However, the structure is not limited to this, as long as it can lock the connecting rod 5b, and furthermore, it may be sandwiched between both sides 7a, 7a of the support member 7, which will be described later.

A support member 7 having a U-shaped cross section and supporting the fork holding cylinder 5 is arranged and fixed in parallel to the pallet side surface 1a so as to wrap around the fork holding cylinder 5 when it is stored. This support member 7 also protrudes downward from the pallet side surface 1a in the same way as the fork holding cylinder 5 described above, and on the outside of the protrusion is a protrusion 7b that rotatably holds the circular rod member 6 described above. is formed.

In this embodiment, the fork holding cylinder 5 and the like are arranged on the pallet front wall 1a, but they can also be arranged on the pallet rear wall 1d. It can also be placed in

In addition, the pallet bottom 1b includes two bottom plates 3,
3 are arranged on the left and right side walls 1e, 1 of the pallet.
The base end portion 3b of each bottom plate 3 is pivoted below f, and is opened outward from the pallet 1. These two bottom plates 3
When these are arranged parallel to the pallet bottom 1b, the end faces of the respective tips 3a are aligned without any gaps. Also, the base end portion 3b of the bottom plate 3
Two cylindrical guide members 4, 4 are fixed to the end face, and a rod member 10 disposed so as to span between the two legs 2, 2 of the pallet is attached to the guide members 4, 4. The base end portion 3b of the bottom plate is pivotally attached to the base end portion 3b. Further, a spring member 18 is disposed between the guide members 4, 4. This spring member 18 biases the bottom plate 3 toward the inside of the pallet 1, and when the pallet 1 is raised in the air with nothing inside, the tip of each bottom plate opened in double-sided directions as shown in FIG. The portion 3a is located on the inner side of the extension line of the pallet side walls 1e, 1f on the side to which the portion 3a is pivoted. In this way, since the bottom plate 3 is biased by the spring member 18, when the waste contained in the pallet 1 is discharged to the outside, the bottom plate 3 is pressed against the side wall 1 of the pallet.
Since it can be opened parallel to or more than e and 1f, it does not become an obstacle to waste discharge. Note that a hinge having a spring member that biases the bottom plate 3 inward may be disposed directly on the end surface of the bottom plate base end portion 3b. In addition, on the outer surface of the bottom plate 3, there are provided in order to allow the bottom plate 3 to close smoothly when the pallet 1 is gradually lowered onto the floor, and to prevent the bottom plate 3 from opening when the pallet 1 is placed on the floor. A roller member 13 having the same height as the distance between the bottom plate 3 and the floor surface is disposed via a support member.

Note that the conventional waste pallet 21 has a hook member 25 on its upper surface for lifting with a crane.
However, since the upper surface of the pallet 1 in this embodiment does not need to be provided with the hook member 25 and is formed flat, the pallet 1 can be stacked. Further, a substantially cubic projection 11 is provided at each corner of the upper part of the pallet 1, and a leg 2 having a recess capable of engaging with the projection 11 is provided at each corner of the pallet bottom 1b. As a result, a plurality of pallets can be stably stacked by engaging the upper protrusion 11 with a recess provided in the leg of another pallet of the same type.

The pallet 1 formed as described above is installed on a predetermined floor with the pair of fork holding cylinders 5 in a stored state, that is, in a state in which they are arranged parallel to the pallet front wall 1a (see Fig. 2). Insert waste from above. When the waste in the pallet 1 has accumulated to a certain extent, the fork holding tube 5 is rotated 90 degrees and the fork 15 of the forklift truck is inserted. At that time, the tip of the fork 15 is inserted so as to come under the bottom plate 3, and the fork 15 supports the bottom plate 3 so that it does not open. Next, with the fork 15 lifted upward, the pallet 1 is carried to a predetermined position, in this embodiment the truck bed section 19, and a support member 7 is attached to the tip corner of the side wall 19a of the truck bed section 19 as shown in FIG. and a protrusion 7b protruding from the support member 7.
The fork 15 is gradually pulled out outward until the tip of the fork 15 no longer hangs on the bottom plate 3, and the bottom plate 3 is opened double-sidedly. Then, the waste in the pallet 1 is dropped into the truck bed section 19. Thereafter, the pallet 1 is returned to a predetermined position and the fork 15 is lowered to lower it onto the floor. At this time, all the waste in the pallet 1 has been taken out, and the bottom plate 3 is urged inward by the spring member 18 and becomes the state shown in FIG.
As the pallet 1 is lowered onto the floor, the bottom plate 3 gradually closes, and finally returns to its original state, that is, a state in which the end surfaces of the tips 3a of the two bottom plates 3 are brought together.

<Effects of the invention> Since the waste pallet of this invention has the above-mentioned configuration, the waste placed in the pallet can be disposed of using a forklift truck commonly used in worksites, etc. Compared to conventional waste pallets, which can only be disposed of by crane, it is more efficient in terms of space and economy.
