Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bogie storage device, and more particularly to a bogie storage device using a mechanical parking device.

For example, there is a general-purpose automated warehouse in which goods placed on pallets are carried in and out by forklifts. Such automated warehouses use, for example, standardized pallets of 1100 mm in length and width. In this case, the size of the articles that can be stored is limited to about 1000 mm in length and width, and there has been a demand for an automated warehouse capable of storing larger articles. However, designing a new large automated warehouse requires a great deal of manufacturing cost and time. Therefore, the inventor of the present invention uses an existing mechanical parking system (see, for example, "Patent Document 1") as a truck storage device, that is, puts a truck on the pallet of the mechanical parking system, So, we envisioned a truck storage device (automated warehouse) in which the truck is pulled out from the pallet by the worker.

However, when implementing the above-described truck storage device, it becomes difficult for a worker to operate the truck due to the increase in the size of the truck and the weight of the articles to be loaded. Therefore, for example, it is conceivable to install a chain conveyor on each pallet and move the cart on the pallet by the chain conveyor. Here, when an article is carried in and out of the rear part of the trolley using a crane, it is required to move the trolley to a position beyond the front end of the device, in other words, to move it beyond the struts of the mechanical parking device. However, since the chain conveyor cannot move the cart beyond the front end of the pallet, the operator must move the heavy cart to a position beyond the front end of the device, which imposes a heavy burden on the worker.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a truck storage device that can easily move a truck on a pallet to a position beyond the front end of the device. .

In other words, the connecting portion 64A between the third connecting member 64 and the fourth endless chain 61 moves leftward by the distance L with respect to the fourth sprocket 59 of the second slider frame 51 . That is, one point on the upper straight portion of the fourth endless chain 61 moves leftward by a distance L relative to the fourth sprocket 59 . Then, when the connecting portion 64A moves leftward by the distance L with respect to the fourth sprocket 59, in other words, when one point on the upper straight portion of the fourth endless chain 61 moves leftward by the distance L, The 4th sprocket 59 and the 2nd sprocket 60 make one rotation in the counterclockwise direction in FIG.

When the second sprocket 60 rotates once, the connecting portion 65A between the second connecting member 65 and the second endless chain 62, and thus the carriage 2 connected to the second connecting member 65, rotates through the second sprocket 60 and, by extension, the carriage 2. The second slider frame 51 is advanced by a distance of 2L (moved leftward in FIGS. 2 and 3). Here, since the second slider frame 51 is advanced by the distance L with respect to the first slider frame 31 and the pallet 21 , the carriage 2 moves forward with respect to the first slider frame 31 and the pallet 21 . will move forward by a distance of 3L (2L+L). That is, in this embodiment, the first shafts 33F and 33R are rotated counterclockwise in FIGS. 2 and 3 to advance the second slider frame 51 by the distance L with respect to the pallet 21 (first slider frame 31). Then, the carriage 2 moves forward by a distance of 3L with respect to the pallet 21 (first slider frame 31).

From the state where the carriage 2 and the second slider frame 51 are positioned at the forward end position (see FIG. 5), the first shafts 33F and 33R are rotated clockwise in FIGS. is retracted (moved to the right in FIGS. 2 and 3) by a distance L with respect to the pallet 21 (first slider frame 31), the carriage 2 is moved to the pallet 21 (first slider frame 31) by a distance 3L only retreat. In addition, referring to FIG. 3 , the carriage 2 includes rollers 7 that can roll on the frame body 52 of the second slider frame 51 . The roller 7 is arranged on the front side of the second connecting member 65 at the rear end of the bottom plate 3</b>A of the housing portion 3 of the carriage 2 . The second slider frame 51 also includes rollers 67 that can roll on the frame body 32 of the first slider frame 31 . A plurality of rollers 67 are arranged on the lower surface of the frame body 52 of the second slider frame 51 at intervals in the front-rear direction. Furthermore, at the ends of the first shafts 33F and 33R of the first slider frame 31, a tool having a polygonal (for example, hexagonal) cross-section to which a rotary tool such as a pneumatic impact wrench is connected is connected as a rotary driving means. A connecting portion (not shown) is formed.

Next, the operation of this embodiment will be described.
First, the operator operates the operation panel (not shown) of the mechanical parking device 11 (see FIG. 1) in the manner of leaving the parking lot to call out the desired pallet 21 (truck 2). Then, the mechanical parking device 11 transports the target pallet 21 to the loading/unloading position while moving the pallet 21 up and down between the storage spaces 12 as necessary. FIG. 2 shows the initial state in which the desired pallet 21 is positioned at the loading/unloading position. The initial state, that is, the pallet 21 is landed on the floor FL (installation surface of the mechanical parking device 11), the second slider frame 51 is positioned at the rearward end position with respect to the first slider frame 31, and the carriage 2 is positioned at the second position. When positioned at the backward end position with respect to the slider frame 51, the wheels 4 of the carriage 2 and the wheels 53 of the second slider frame 51 are on the floor FL.

In this state, when the rotating tool is operated to rotate the first shaft 33F counterclockwise in FIGS. , 38 and the third endless chain 42 wind in the counterclockwise direction in FIG. At this time, the chain speed of the third endless chain 42 is twice the chain speed of the first endless chain 41 . Since the second slider frame 51 is connected to the first endless chain 41 via the first connecting member 63 , it moves forward with respect to the first slider frame 31 and the pallet 21 .

On the other hand, the upper linear portion of the third endless chain 42 and the upper linear portion of the fourth endless chain 61 are connected by the third connecting member 64, and the chain speed of the third endless chain 42 is equal to that of the first endless chain 41. is twice the speed of the second slider frame 51, so the number of rotations of the first shafts 33F, 33R, the first sprockets 35, 37 and the third sprockets 36, 38 is are identical. Since the carriage 2 and the upper straight portion of the second endless chain 62 are connected by the second connecting member 65 , the carriage 2 can reduce the chain speed of the fourth endless chain 61 with respect to the second slider frame 51 . Move forward at double speed. That is, if the moving speed of the second slider frame 51 with respect to the first slider frame 31 (pallet 21) is V, the carriage 2 accelerates to a speed of 3V (2V+V) with respect to the first slider frame 31 (pallet 21). to move forward.

In other words, when the second slider frame 51 advances by a distance L with respect to the first slider frame 31 (pallet 21), the carriage 2 advances by a distance 3L relative to the first slider frame 31 (pallet 21). Here, in FIG. 4, the front end of the truck 2 exceeds the front end position P of the truck storage device 1, in other words, the post (not shown) of the mechanical parking device 11, and the front end of the second slider frame 51 reaches the truck storage device. 1, the front end position P is not exceeded. The wheels 4 of the truck 2 and the wheels 53 of the second slider frame 51 roll on the floor FL as the truck 2 and the second slider frame 51 move forward.

FIG. 5 shows a state in which the second slider frame 51 is positioned at the forward end position with respect to the first slider frame 31 and the carriage 2 is positioned at the forward end position with respect to the second slider frame 51 (hereinafter referred to as the "carriage forward end state"). ) is shown. In this carriage forward movement completion state, the rear end of the carriage 2 is positioned forward (left side in FIG. 5) of the front end position P of the carriage storage device 1, in other words, the strut (not shown) of the mechanical parking device 11. there is The first drive mechanism and the second drive mechanism are arranged so that the carriage 2 reaches the forward end position with respect to the second slider frame 51 when the second slider frame 51 reaches the forward end position with respect to the first slider frame 31 . has a mechanical stopper (not shown) for restricting movement of the second slider frame 51 and the carriage 2 .

On the other hand, when returning (storing) the trolley 2 to the mechanical parking device 11 after the goods (not shown) have been carried in and out of the trolley 2 in the state where the trolley has advanced forward in FIG. The rotating tool connected to the tool connecting portion of the first shaft 33F is operated to rotate the first shaft 33F clockwise in FIG. Accordingly, when the second slider frame 51 retreats by a distance L with respect to the first slider frame 31 (pallet 21), the carriage 2 retreats by a distance 3L with respect to the first slider frame 31 (pallet 21). At this time, the wheels 4 of the truck 2 and the wheels 53 of the second slider frame 51 roll on the floor FL as the truck 2 and the second slider frame 51 move forward.

When the second slider frame 51 reaches the rearward end position with respect to the first slider frame 31 and the carriage 2 reaches the rearward end position with respect to the second slider frame 51 (see FIG. 2), the operator can move the rotary tool from the first shaft 33R, and moves forward of the front end position P of the truck storage device 1 (outside the gate (not shown) of the mechanical parking device 11). The first drive mechanism and the second drive mechanism are arranged so that the carriage 2 reaches the rearward end position with respect to the second slider frame 51 when the second slider frame 51 reaches the rearward end position with respect to the first slider frame 31 . has a mechanical stopper (not shown) for restricting movement of the second slider frame 51 and the carriage 2 .

Next, the operator operates the operation panel (not shown) of the mechanical parking device 11 (see FIG. 1) in the manner of entering and leaving the pallet 21 (truck 2) located at the loading/unloading position to the mechanical parking device 11. is stored in the predetermined storage space 21 of .
