Abstract

<P>PROBLEM TO BE SOLVED: To provide a pallet tower (a pallet storage device) capable of charging/discharging pallets of the designated number from a lower portion thereof when tens of pallets for general physical distribution are stacked, so that the pallet tower of the present invention can easily charge/discharge the pallets of the designated number by hands or by a hand lift without using any forklift, and the space can be saved since tens of pallets can be stored according to the present invention. <P>SOLUTION: When discharging pallets, the pallets of the designated number stacked and stored in a pallet tower and counted from the bottom side are left behind, and all the pallets thereabove are slightly elevated. Thus, the pallets of the designated number can be easily taken out from a lower part of the pallet tower. When charging the pallets, all pallets are elevated above the height of the pallets of the designated number, and the pallets of the designated number can be charged from the lower part of the pallet tower. The pallet tower can easily charge/discharge the pallets of the designated number of one to ten into/from the lower part by using a hand lift. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a general pallet storage apparatus often used for physical distribution.

  The industry uses very many general pallets for logistics. Therefore, pallets to be used for a certain period must be kept.

  Currently, pallets are often stacked in layers above and outside the building. Up to about 10 sheets are manually stacked, and 10 sheets are stacked on top of the stacked 10 sheets using a forklift, and similarly stacked on 30 and 40 sheets.

  The next time you use pallets, use the forklift to lower the number of pallets you use from the top, and then divide them one by one by hand.

This method requires a technique of forklift that stacks pallets well and is dangerous. In addition, a palletizer (a machine that automatically puts an article on a pallet) may be accompanied by a machine that stocks the pallet. The mechanism is different.

  In order to stack and store pallets, a device is provided that allows the necessary number of pallets to be loaded and ejected manually from the bottom by hand lift (hand pallet truck) or manually.

  In a state where dozens of pallets are stacked, the necessary number of pallets can be discharged from the lower part by leaving the necessary number of pallets below and raising all the pallets on the pallet slightly.

  In the case of pallet input, all the pallets above the bottom pallet are raised slightly above the number of pallets to be input. As a result, a specified number of pallets can be loaded from the bottom.

  From the top, when loading and unloading pallets, you can load and unload any number of forklifts.

  In the pallet tower of the present invention, when stacking and storing pallets, the pallet can be loaded and unloaded at the bottom. Accordingly, even if a forklift is not used, the pallet can be loaded and unloaded with only a hand if it is one or two, and a handlift (hand pallet truck) if it is several or more.

  In addition, more pallets can be stacked than usual pallet stacking storage, saving space. Since there is no need to use a forklift, there is little danger. It is characterized by the ability to insert and discharge pallets from the bottom of the specified number instead of one by one.

  Embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a perspective view when five pallets are discharged from the pallet tower. First, the slider 2 is moved up and down to a height at which the claw 1 enters the lift hole of the sixth pallet from the bottom, and the claw 1 is inserted. The claw 1 and the slider 2 are on the front, rear, left and right of the pallet tower and are moved in synchronization. Next, as shown in FIG. 2, when the slider 2 is slightly raised while the claw 1 is put in the lift hole of the pallet, only the lower five pallets are left and the other upper pallets are lifted. In this state, since the load of the other pallets is not applied to the lower five pallets, it can be easily taken out from the lower part of the pallet tower by a hand lift or the like.

  FIG. 3 is a perspective view when eight pallets are loaded into the pallet tower from below. First, the slider 2 is lowered to a height at which the claw 1 can enter the lift hole of the bottom pallet, and the claw 1 is inserted. Next, as shown in FIG. 4, the slider 2 is raised to a height at which eight pallets are placed on the lower side. Eight pallets can be put here with a hand lift or the like.

  The pallet number of 5 sheets at the time of discharge and 8 sheets at the time of loading described so far can be changed from 1 to about 10 sheets and automatically operates. Finally, the process returns to the standby position in FIG. At the standby position, the claw 1 is removed from the pallet so that the slider 2 can freely move up and down.

  In addition, a pallet guide 3 may be provided to neatly stack the pallets. The front upper part is obstructed when using a forklift, so a pallet guide like an openable door is desirable. The pallet tower of the present invention is characterized in that the pallet is loaded and unloaded from the lower front side. If the rear side is the same as the front side, the pallet tower can be loaded and unloaded from the front side and the rear side.

  The embodiment of FIG. 6 is a pallet tower made of sheet metal and having an elevator 4 that moves up and down. A claw 1 that can be automatically inserted into and removed from the lift hole of the pallet is located at the twelfth pallet from the bottom. Before and after. The elevator 4 is suspended by a wire 5 and can be moved up and down by a rotating shaft 6.

  As shown in FIG. 7, when the pallet is loaded, an arbitrary number of pallets of up to 10 are placed on the elevator 4, the elevator 4 is raised to the height of the claw 1, and then the claw 1 is put into the lift hole of the pallet. . Thereby, a pallet can be thrown in from the lower part of arbitrary quantity pallet towers. When there are several pallets stocked above, when the pallet on the elevator touches the stocked pallet, if the claw 1 is pulled out, the stocked pallet and the loaded pallet are integrated into the elevator 4. Is raised to the height of the claw 1 and then the claw 1 is put into the lift hole of the pallet.

  When the pallet is discharged, the elevator 4 is raised so that the claw 1 is on the pallet immediately above the designated number of pallets (five in FIG. 8) as shown in FIG. Insert it into the pallet lift hole. After that, when the elevator 4 is lowered, five pallets can be taken out from the lower part of the pallet tower.

  The second embodiment is characterized in that the claw 1 is installed at a position about the 12th sheet from the bottom. There are two claws 1 at the front and rear of the pallet tower, but it is safe if there are several places for every 10 pallets. The pallet guide 3 is a pallet guide, but may be a guide for the elevator 4. The standby position of the elevator 4 according to the second embodiment is the lower end as shown in FIG. 6 regardless of the presence or absence of the pallet. The wire 5 may be a conveyor chain or the like, and is synchronized by the rotating shaft 6 in order to raise and lower the elevator 4 smoothly.

  Where a large amount of general pallets are used, many pallets are stacked and stored. In this case, several pallets cannot be loaded and unloaded unless a forklift is used. Since the pallet tower according to the present invention can input and discharge a specified number of pallets from the lower side, only a hand lift or a hand is required. Using a forklift can be dangerous and expensive to maintain.

  If a pallet is stacked and stored without using a forklift, only about 10 levels are stacked. This is because one or two sheets are inserted and discharged manually from above. The pallet tower according to the present invention can input and discharge a specified number of pallets from the bottom, so that tens of pallets can be stacked and stored. It is very space saving.

  General pallets are used very often in manufacturing factories and distribution warehouses, but they are very useful because there is no storage device for the pallets that can input and discharge a specified number (variable) of pallets from the bottom.

It is a perspective view at the time of discharging a pallet from a pallet tower. Example 1 It is a perspective view in the state where a pallet can be discharged from the pallet tower. Example 1 It is a perspective view at the time of throwing a pallet into a pallet tower. Example 1 It is a perspective view in the state where a pallet can be put into the pallet tower. Example 1 It is the perspective view which showed the standby state when not using the pallet tower. Example 1 It is a perspective view of the pallet tower of an elevator specification. This figure shows the standby position. (Example 2) It is a perspective view when eight pallets are thrown into the pallet tower. (Example 2) It is a perspective view when discharging five pallets from the pallet tower. (Example 2)
