Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pallet top attachment / detachment aid for drying and stacking pallets used in order to efficiently carry out cargo handling work using a forklift or the like through a top.

[0002]

[Prior art]

 Generally, when wet or damp pallets are piled up in multiple stages to be naturally dried, or forcedly dried by a blower or dryer, it is called a coma to improve the air permeability between the pallets. A member with a thickness of several centimeters is placed between the pallet and the pallet, and a gap is provided between the pallets.

Conventionally, as a work for providing the tops between the pallets, a work such as placing the tops at four corners of the pallet placed on the ground and placing another pallet on the tops is sequentially repeated by a hand or a forklift, and the like. I was stacking about 10 pallets through. Also, after drying the stacked pallets as described above, when removing the commas between the pallets, the top pallet should be removed manually or by a forklift in the same manner as above, and then the pieces on the next pallet should be removed. I removed the next pallet by removing it manually and using a forklift again to remove the frames placed between the pallets.

[0004]

[Problems to be solved by the device]

 However, if the work of attaching and detaching (installing and removing) the top is performed by the conventional work method as described above, it takes a lot of time and labor and is very inefficient. In particular, at least two people were required to reload the heavy pallets while manually removing the frames, which was a considerable amount of effort. Further, in the work using a forklift, etc., the work of loading (or lowering) the pallets and the work of attaching the tops must be performed alternately, which is a very troublesome and troublesome work.

The present invention was devised to solve the above problems, and the purpose of the present invention is to make it possible to easily and easily store each piece from a pallet stacked in multiple stages via the pieces. Another object of the present invention is to provide an auxiliary tool for pallet piece attachment / detachment, which can be removed in a short time and can be easily and quickly installed between pallets.

[0006]

[Means for Solving the Problems]

 Therefore, the present invention has the following configuration in order to achieve the above object. That is, the invention according to claim 1 has a structure in which locking projections are provided on the same side of the long member so as to project at a predetermined interval. According to the second aspect of the present invention, the locking projections can be outwardly protruded and folded upward at the same side of the elongated member having the latching portion on the upper side at predetermined intervals. This is the structure provided.

According to the third aspect of the present invention, locking projections are projected outwardly and upwardly on the same side of a long member having a hooking portion on the same side at predetermined intervals. In addition to being provided so as to be foldable, the projecting portion of the locking projection that is folded upward is housed in the recess formed in the elongated member.

[0008]

[Action]

 In the above-mentioned structure according to claim 1, when a plurality of tops are provided between the pallets stacked in multiple stages, first, in the pawl insertion openings such as forklifts of the pallets in each stacked stage, Inserting the respective locking projections provided on the long member, auxiliary pieces for attaching / detaching the tops are provided at four positions on the pallet stacked in multiple stages.

In this case, the uppermost locking projection piece is locked on the upper surface side of the lower surface plate of the uppermost pallet. The next locking projection is suspended in the pawl insertion opening near the top plate of the second pallet from the top. The locking projection of the pallet in the third tier from the top is located slightly below the position of the pawl insertion opening in the pallet in the second tier from the top. In this way, as the lower pallet is approached, the position of the locking projection in the claw insertion opening is gradually lower than the position of the upper pallet.

[0010] As described above, the auxiliary tools for attaching / detaching the tops are provided at four positions of the pallets stacked in multiple stages, and then a forklift or the like is inserted into the forklift or the like insertion opening of the forklift of the uppermost pallet. To raise the top pallet. As a result, the respective locking projections provided on the long member so as to have a dimension interval larger than the thickness dimension of one pallet, the uppermost pallet is lifted, and When the next locking projection is locked to the inner surface of the upper surface plate of the lower pallet and the uppermost pallet is further lifted, this pallet is lifted with a predetermined gap from the uppermost pallet. After that, the pallets on each stage are similarly lifted from the top.

Due to this, a gap larger than the height dimension of the tops is generated between the pallets of each stage. By placing a plurality of tops on the pallet of each stage from this gap and lowering the pawls of the forklift or the like, The pallets for each tier are placed on each top, and the pallets for each tier are stacked via this top so that the pallets for each tier do not adhere to each other and are used for ventilation between the pallets. You will be able to maintain the gap.

In addition, when removing the respective frame attachment / detachment aids from the pallets stacked as described above and after drying the pallets, when removing the frames provided between the pallets, the frames are stacked through the frames. Attach the piece attachment / detachment auxiliary tools near the four corners of the pallet as described above. Next, insert the pawls of a forklift or the like into the pawl insertion openings of the forklift or the like of the top pallet and lift the top pallet. As a result, the locking projections are sequentially locked from the top to the pallets in each stage, and the pallets are lifted away from the top in order from the top stage. Then, a gap wider than the height of the tops is formed between the pallets, and the tops on each pallet can be easily removed from this gap.

Further, in the structure according to the second aspect, while the hooking portion formed on the upper portion of the long member is hooked on the uppermost pallet that is stacked in multiple stages, fork lifts and the like of the pallets of each stage are formed. The locking projections provided on the long member are locked in the claw insertion openings. In this way, auxiliary pieces for attaching / detaching the tops are provided at four positions on the pallet stacked in the same manner as described above. Since the weight of the entire pallet is applied to the hooking portion when the uppermost pallet is lifted, it is formed to be strong in strength.

The operation of providing a plurality of pieces between the pallets stacked in multiple stages and the operation of removing the pieces provided between the pallets by using the piece attachment / detachment auxiliary tool are the same as those of the operation description of claim 1. Since it exists, the description is omitted. Since the locking projection of the piece attaching / detaching auxiliary tool according to claim 2 can be folded upward, it is possible to change the pieces from the pallets stacked in multiple stages via the pieces as described above. After removing the pallets, when the pallets on each stage are lowered, and when the pallets are piled up, the locking projections of the auxiliary tools for attaching / detaching the tops that come down with the pallets contact the end of the pallet. Then, the long member is folded. Therefore, since each frame attachment / detachment auxiliary tool is in a state of being hooked to the pallet only by the hooking portion at the top, it can be easily removed from the stacked pallets.

Further, in the structure according to the third aspect, when the locking projection is folded, the projection of the locking projection is housed in the recess formed in the long member. The protrusions do not get caught on the pallet, and it is possible to remove the frame attachment / detachment aids from the pallets that are stacked more smoothly. Since the work using the auxiliary tool for attaching and detaching the frame is the same as that of the first and second aspects, the description thereof will be omitted.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 4 show an embodiment of a piece attaching / detaching tool according to the present invention. This piece attaching / detaching tool 1 includes a long member 3 provided with a hook 2 on the upper portion thereof. The locking projections 4 are provided on the same side at predetermined intervals so as to project outward and be foldable upward.

More specifically, the elongated member 3 is a straight metallic member having a rectangular cross section and has a length comparable to the height of the pallets A stacked in about 10 steps. A hooking portion 2 is provided at a right angle on the upper end of the long member 3, so that the hooking portion 2 can be hooked on the uppermost pallet of the pallets A stacked in multiple stages. Further, the hook 2 is made of a metal member having a strength capable of supporting the entire pallets stacked in multiple stages as described later.

Holes 5 are formed in the elongated member 3 on the same side below the hook 2 at a distance of about 10 mm added to the thickness of one pallet A and a top B to be described later. The locking projection 4 is hingedly connected through the hole 5. That is, as shown in FIG. 4, the locking projection 4 is formed by the shackle 6, the stop pin 7, and the metal plate 8 which is the projection. A metal plate 8 is fixed to the lower end of the shackle 6 by welding or the like. The shackle 6 has a stopper pin 7 inserted into the hole 9 of the shackle 6 and the hole 5 of the elongated member 3 so as to be hingedly connected to the elongated member 3. In this case, the rear end 8a of the metal plate 8 is normally in contact with the elongated member 3 and projects horizontally in the direction perpendicular to the elongated member 3. Of course, the shackle 6 may be fixed to the elongated member 3 so as to project upward in an acute angle. The metal plate 8 can lock the pallet A and is shorter than the height dimension of the claw insertion opening a of the pallet A forklift or the like.

When a plurality of tops B are provided between the multi-tiered pellets A by using the top attachment / detachment auxiliary tool 1 having the above-described configuration (see FIGS. 3 and 4), first, The hooking portion 2 is hooked on the uppermost pallet A of the pallets A stacked on top of each other, and the stoppers provided on the long member 3 are provided in the pawl insertion openings a of the forklifts of the pallets A of the respective tiers. The metal plate 8 (protrusion) of the projecting piece 4 is inserted. In this way, the frame attachment / detachment assisting tools 1 are provided at four locations near the four corners of the pallets A stacked in multiple stages.

In this case, the metal plate 8 of the locking projection 4a at the uppermost stage is located closer to the lower surface of the upper surface plate b of the second palette A from the uppermost stage. The metal plate 8 of the next locking projection 4b is suspended in the pawl insertion opening a near the top plate c of the third pallet A from the top. The position of the metal plate 8 of the locking projection 4c of the fourth pallet A from the top is slightly lower than the position of the third pallet A from the top with respect to the claw insertion opening a. Thus, as the lower pallet is moved, the position of the metal plate 8 of the locking projection 4 inside the claw insertion opening a is gradually lower than the position of the upper pallet A.

In this way, after the top attachment / detachment assisting tools 1 are provided at four positions of the pallet A stacked in multiple stages, the pawls such as a forklift are inserted into the pawl insertion openings a of the forklift of the topmost pallet A. Then, the claws are raised to lift the uppermost pallet A. As a result, the metal plates of the respective locking projections 4 (4a, 4b, 4c ...) provided on the long member 3 so as to have a dimension interval larger than the thickness dimension of one pallet. As the uppermost pallet A is lifted, 8 is successively locked to the inner surface of the top plate of each pallet A, and the pallets A are sequentially lifted with a predetermined gap from the top. .

As a result, a gap larger than the sum of the thicknesses of one pallet A and the top B is generated between the pallets A on each stage. A plurality of tops B are placed on the respective pallets A through the gaps, and then the pawls of a forklift or the like are lowered, so that the pallets A of the respective tiers are placed on the respective tops B. At this time, the metal plate 8 of the locking projection piece 4 of the lower pallet A of each piece attachment / detachment auxiliary tool 1 provided on the stacked pallets A contacts the lower surface plate d of the pallet A and is folded upward. It will be in a folded state. Therefore, it is possible to easily remove each piece attachment / detachment auxiliary tool 1 from the stacked pallet A.

In this way, the pallets A of each tier are in a state of being stacked via the top B, and the pallets A of each tier do not adhere to each other, and a ventilation gap is maintained between the pallets A. become able to. After doing this, the top attachment / detachment auxiliary tool 1 is removed, and the pallets A stacked in multiple stages by natural drying or the like are dried. Further, after removing the pallets A, when removing the tops B provided between the pallets A, the auxiliary tools 1 for attaching / detaching the tops are placed near the four corners of the pallets A stacked via the tops B as described above. Install.

Next, a pawl such as a fork lift is inserted into the pawl insertion opening a of the forklift or the like of the uppermost pallet A, and the uppermost pallet A is lifted again. As a result, the metal plates 8 of the locking projections 4 are sequentially locked from the top to the pallets A at the respective stages, and the pallets are lifted away from the top B in order from the top. Then, a gap wider than the thickness (height) of the top B is formed between the pallets A, and the top B on each pallet A can be easily removed from this gap.

FIGS. 5 to 6 show a frame attachment / detachment assisting tool 1 according to another embodiment of the present invention. In this embodiment, the elongated member 3 is projected on the same side of the elongated member 3 at a predetermined interval. The locking projection 4 thus fixed is provided. In this case, the locking projection 4 is formed only by the metal plate 8 and is fixed by welding or the like so as to project from the same side in the horizontal direction at a right angle to the elongated member 3. When the locking projection 4 is fixed to the long member 3, the hook 2 may be provided at the upper end of the long member 3 (see FIG. 5) or may not be provided (see FIG. 6). If the hooking portion 2 is not provided, the uppermost locking projection piece 4 can function as the hooking portion 2, and the uppermost hook is engaged with the pawl insertion opening a of the forklift of the uppermost pallet A. By inserting the stop projections 4 and locking the other locking projections 4 to the respective pallets A, and lifting the uppermost pallet A with a forklift or the like, the entire pallet is stacked in multiple stages. Can be lifted.

The attachment / detachment work of the top B is the same as that of the above-mentioned embodiment, and the description thereof will be omitted. Incidentally, in the case of this embodiment, the long member 3 and the locking projection 4 may be integrally formed. FIG. 7 shows a main part of a frame attachment / detachment assisting tool 1 according to still another embodiment. The frame attaching / detaching aid 1 according to this embodiment has the locking projection 4 hingedly connected to the elongated member 3. Since the configuration is almost the same as that of the example, the different configuration, action and effect will be described.

In the case of this embodiment, the shackle 6 and the metal plate 8 when folded upward are stored on the side portion above the hole 5 for hinge-connecting the locking projection 4 to the elongated member 3. Each of the recesses 10 that can be formed is formed. The back surface of the metal plate 8 housed in the recess 10 is preferably housed flush with the side surface of the elongated member 3. Of course, it may be housed inside the long member 3 rather than the side surface.

Since the locking projections 4 are housed in the long member 3 when folded as described above, the locking projections 4 are locked to the side portions of the pallet A when the stacked pallets A are lowered. It is possible to prevent the projecting pieces 4 from coming into contact with each other, and it is possible to more smoothly remove the piece attaching / detaching auxiliary tool 1 from the stacked pallets A. The hook 2, the elongated member 3, and the locking projection 4 of the above-described auxiliary device 1 for attaching / detaching the top of the present invention are not made of steel, but have strength, and are made of a light metal member such as aluminum or titanium, You may form with the other hard member. Further, the number of pallets to be stacked is not limited to 10 and any number of pallets may be stacked if workability is good. In this case, it is necessary to use a long member having an appropriate length having locking projections that match the number of pallets to be stacked.

Further, the metal plate 8 is hingedly connected to the long member 3, and the lower surface of the rear end of the metal plate 8 or the long member is attached so that the metal plate 8 does not drop downward from the horizontal direction. By fixing the locking pieces, the metal plate 8 normally projects horizontally and can be folded upward.
