Description

  The present invention is applied to an integrally molded plastic pallet, and more particularly to a plastic pallet stacking structure in which pallets can be stacked in a stable state, and one pallet can be conveniently disassembled.

  As shown in FIG. 1, the external appearance of a known integrally molded plastic pallet is rectangular, and includes a loading surface 1 for loading cargo, a bottom surface 2 installed on the bottom of the pallet, and an average of the loading surface 1 and the bottom surface 2. It includes a plurality of support columns 3 installed between them. A notch 4 for inserting a forklift claw is formed between two adjacent support columns 3. After the cargo is stacked above the pallet, the cargo placed on the pallet and the loading surface 1 is lifted by a forklift claw and transported to the designated designated position.

  When cargo is not placed on a general pallet, it is usually stored in a warehouse in a further stacked form to save storage space. However, since the surface of the pallet is made of a plastic material, the surface of the pallet is smooth, so when the pallets are stacked, the loading surface of the lower pallet and the bottom surface of the upper pallet can easily slide and tilt and fall down. Yes, pallets cannot be stacked high, and a relatively large storage space is required.

  Accordingly, the trader designs a known pallet as shown in FIG. 2, and the pallet is provided with a plurality of support pillars 6 slightly inclined at the periphery and center of the bottom of the loading surface 5 so that the bottom of the loading surface 5 A notch groove portion 7 that is recessed upward is provided between two adjacent support pillars 6. Among them, the upper surface of each support column 6 is larger than the bottom surface, and further includes a storage groove portion 8 in the direction of opening the upper surface of the loading surface 5. When the pallets are stacked on top of each other, the support pillars 6 of the upper pallet are inserted into the storage grooves 8 of the corresponding lower pallet, whereby the plurality of pallets are stacked and positioned in a stable state, and the storage space is reduced.

  However, although the known pallet of FIG. 2 is provided with the notch groove portion 7 for inserting the tab of the forklift, the weight pressure received by the lower pallet becomes larger when the pallet is stored and stacked in the warehouse. Since the support pillar 6 of the pallet is pressed and caught in the storage groove 8 of the lower pallet, the pallet is difficult to separate. In addition, as shown in FIG. 3, at the moment when the forklift claw is inserted into the notch groove portion 7 from one side of the pallet to lift the upper pallet, the upper pallet is inclined at an angle, and a plurality of support pillars 6 on the forklift side are provided. Is separated from the storage groove portion 8, but the other one side which is opposed cannot be separated effectively due to the angle inclination, causing difficulty in operation.

  In light of the various inconveniences of using known pallets, the inventor has made use of research and practical experience accumulated in related fields over many years to create a stack structure that can be applied particularly to plastic pallets. As a result, the pallets can be stacked in a stable state, and at the same time, the stacked pallets can be conveniently separated for storage logistics work in the warehouse, making it difficult to stack and separating because of the long stacking time. Improves the disadvantages of known pallets, which are difficult.

  The purpose of the present invention is to provide a stacking structure that can be applied to an integrally molded plastic pallet. Stacking the pallet in a stable state saves storage space and smoothes the pallet stacked further by forklift. It can be separated into the storage work in the warehouse, achieving the purpose of convenient use.

  In order to achieve the above-described object, the plastic pallet stacking structure of the present invention extends a plurality of hollow supports downward around the center and bottom of the pallet loading surface. A cross-shaped support bone is provided in the hollow recess of each support on the loading surface. At the bottom of each support that corresponds to the support bone, a cross-shaped stereotactic groove that is recessed upward is installed. The stereotactic groove divides the support bottom into four support pillars, and the top height of the stereotaxic groove is stacked. Lower than the bottom height of the surface. When stacking the upper pallet on the loading surface of the lower pallet, the four support pillars of each support of the upper pallet are inserted into the corresponding hollow recesses on the lower pallet loading surface, and are positioned. The letter-shaped support bone presses the upper part of the cross-shaped stereotaxic groove of the upper pallet support so that the bottom surface of the upper pallet and the upper surface of the lower pallet hold the fork lift claw and hold the lift.

  Using the structure described above, when loading cargo on a pallet, the four support pillars at the bottom of each support distribute the weight of the cargo on average, so that the pallet can carry heavier cargo. The cruciform support bone in the hollow recess has an effect of strengthening the pallet structure and effectively improves the durability of the pallet.

  Further, when stacking and storing pallets in a warehouse, each support of the upper pallet is inserted into a hollow recess on the corresponding lower pallet loading surface and positioned, so that the storage volume is reduced and the lower pallet Since the upper part of the cruciform support bone in the hollow recess presses the upper part of the cruciform stereotaxic groove of the upper pallet support, the outer wall surface of the upper pallet support does not get caught in the hollow recess and is constant between the two. Spacing is maintained. As a result, when the forklift claw is inserted from one side of the pallet and the upper pallet is lifted, a space is created around each support, and the forklift is inclined at a certain angle along the pallet. Lifts the upper pallet smoothly and improves the disadvantage that it becomes difficult to separate the pallet for a long time.

  The stacking structure applied on the plastic pallet of the present invention stacks the pallets in a stable state, saves storage space, and smoothly separates the stacked pallets with a forklift to perform storage work in the warehouse. It has the effect of making it convenient to use.

It is a figure which shows the state which piled up the well-known pallet. It is a figure which shows the state which accumulated another known pallet. It is a figure which shows the state which lifted the pallet of FIG. 2 with the forklift. It is a three-dimensional external view of this invention palette.

It is a three-dimensional external view regarding the 2nd Example of this invention support body. It is a figure which shows the state which accumulated the 2nd Example of this invention pallet.

  Next, based on the technical means of the present invention, implementation methods suitable for the present invention are enumerated and further described with reference to the drawings.

  As shown in FIGS. 4 to 7, in the plastic pallet stacking structure of the present invention, a plurality of hollow supports 20 are extended downward around and around the bottom of the pallet stacking surface 10. A cross-shaped support bone 31 is provided in the hollow recess 30 of each support 20 on the loading surface 10, and a cross-shaped stereotactic groove 21 recessed upward is formed at the bottom of each support 20 corresponding to the support bone 31. The positioning groove portion 21 divides the bottom of the support 20 into four support columns 22, and the upper height of the positioning groove portion 21 is lower than the bottom surface height of the loading surface 10. When the upper pallet is stacked on the loading surface 10 of the lower pallet, the four support pillars 22 of each support 20 of the upper pallet are inserted into the corresponding hollow recesses 30 on the corresponding lower pallet loading surface 10 and are positioned. The cruciform support bone 31 in 30 presses the upper part of the cruciform localization groove portion 21 of the upper pallet support 20, so that the forklift claw is inserted into the bottom surface of the upper pallet and the top surface of the lower pallet. Hold the lifting interval.

  As shown in FIG. 5 and FIG. 6, a cross-shaped control portion 32 that protrudes into the hollow recess 30 by forming the thickness of the cross-shaped localization groove portion 21 that is recessed upward is formed to control the cross-shaped support bone 31. Stand on part 32.

  Since the heights of the upper surface of the support bone 31 and the upper surface of the loading surface 10 are made equal and the hollow recess 30 is divided into four parts, it has an effect of strengthening the pallet structure and can effectively increase the durability of the pallet. . Furthermore, a columnar connecting column 311 is provided at the center of the cross-shaped support bone 31 to increase the structural strength of the support bone 31 and prevent the material from shrinking when the support bone 31 is injection molded.

  Using the structure described above, when loading cargo on a pallet, the four support posts 22 at the bottom of each support 20 distribute the average weight of the cargo so that the pallet loads more heavy cargo. The cruciform support bone 31 in the hollow recess 30 has the effect of strengthening the pallet structure and effectively improves the pallet durability when the cargo is loaded. To improve.

  Further, as shown in FIGS. 7 and 8, when the pallets are stacked and stored in the warehouse, the support members 20 of the upper pallet are inserted into the hollow recesses 30 on the corresponding lower pallet stacking surfaces 10 and are positioned. The upper volume of the support 20 of the upper pallet is hollow because the storage volume is reduced and the upper part of the cruciform support bone 31 in the hollow recess 30 of the lower pallet presses the upper part of the cross-shaped localization groove 21 of the upper pallet support 20. The inside of the recess 30 is not pressed and caught, and a constant interval is maintained between the two. As a result, when a forklift claw is inserted from one side of the pallet and the upper pallet is lifted, a space is created around each support 20 and is inclined at a certain angle along the pallet. The forklift lifts the upper pallet smoothly and improves the disadvantage that it becomes difficult to separate the pallet when stacked for a long time.

  As shown in FIG. 4, a guide groove portion 40 having a concave shape is provided between two adjacent supports 20 on the bottom surface of the stacking surface 10, and each guide groove portion 40 is a chamfered portion inclined to the bottom surface edge of the stacking surface 10. 41 is provided. The chamfered portion 41 is convenient for inserting a claw of a forklift into the guide groove portion 40 and lifting the pallet to move the position, and at the same time, can eliminate the stress concentration phenomenon when the guide groove portion 40 receives an external force.

  As shown in the drawing, a plurality of fixing holes 11 are provided on the upper surface of the loading surface 10, and slip stoppers 12 slightly projecting from the upper surface of the loading surface 10 are provided in each fixing hole 11. It prevents the cargo placed on the surface 10 from sliding and achieves the effect of stacking in a stable state.

  As shown in FIGS. 9 and 10, at the time of implementation, a plurality of reinforcing bones 33 are erected on the inner side of the hollow recess 30 at positions corresponding to the respective support pillars 22, and the upper surfaces of the plurality of reinforcing bones 33 and the cross-shaped control unit 32. When the upper pallet and the lower pallet are stacked together, the upper ends of the support bones 31 of the hollow recesses 30 of the lower pallet press the upper part of the localization groove 21 of the support 20 of the upper pallet, Since the bottom ends of the support pillars 22 of the pallet also press the upper surfaces of the plurality of reinforcing bones 33 in the hollow recesses 30 of the corresponding lower pallet, the stability when stacking the pallets is enhanced.
