Abstract

PROBLEM TO BE SOLVED: To improve the efficiency of the work by connecting a rotation driving source and the shafts by a power transmitting means, connecting one edge of a link to the shaft, and connecting the other edge of the link with a lower part of a cargo receiving part. SOLUTION: One rotation driving source 10 is installed on a base 8, the shaft 11 are rotatably installed on the both sides of the base 8, the rotation driving source 10 and the shafts 11 are connected by a power transmitting means 12, one edge of a link 13 is connected with the shaft 11, and the other edge of the link 13 is connected with a lower part of a cargo receiving part 9. The rotation driving force of the rotation driving source 10 is transmitted from a first chain sprocket 14 to a second chain sprocket and the shaft 11, and when the shaft 11 is rotated, the link 13 also makes the different movements in a vertical direction corresponding to the rotating direction. That is, the cargo receiving part 9 is vertically moved on the basis of the difference of the rotating directions of the rotation driving mechanism 10, and the movement in a horizontal direction is added by the circular movement of the link 13.

SUMMARY OF THE INVENTION The present invention relates to a loading / unloading device arranged at a loading / unloading position of a multi-stage high-rise shelf constituting a three-dimensional automatic warehouse, wherein one rotation drive source is provided on a base of the loading / unloading device, and A shaft is rotatably disposed on both sides of the shaft, and the rotation drive source and the shaft are connected by power transmission means. One end of a link is connected to the shaft, and the other end of the link is connected below the load receiving portion. The above-mentioned problem has been solved.

[0005] As another structure of the present invention, there is provided a loading / unloading device arranged at a loading / unloading position of a multi-stage high-rise shelf constituting a three-dimensional automatic warehouse.
A shaft is rotatably arranged on both sides of the base, and the rotation drive source and the shaft are connected by power transmission means. One end of the link is connected to the shaft, and the other end of the link is located below the load receiving portion. When the load receiving portion is connected to the lowermost position, the other end is lower than one end, thereby reducing the depth of the pit.

As another two structures of the present invention, the loading / unloading device comprises a table lifter and a horizontally movable frame mounted on the upper surface of a table which moves up and down the table lifter. When storing, on both sides of the box, a cam plate formed with a cam groove having a predetermined shape is fixed, and a cam follower at the lower part of the gantry is inserted into the cam groove, and when the gantry is raised,
The above-mentioned problem is solved as a structure in which a cam follower rolls in a cam groove and the gantry moves horizontally along the shape of the cam groove.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is a perspective view of a three-dimensional automatic warehouse in which the present invention is arranged. Shelf 2,
It comprises a stacker crane 3, a stocking / unloading device 4 of the present invention, a control device 5 for these and a stock management device 6.

2 and 3, a pit 7 is dug on the loading / unloading side of each of the shelves 2A constituting the multi-stage high-rise shelf 2, and a base is disposed on the bottom of the pit 7. 8 and a load receiving portion 9 provided on the base 8 so as to be vertically movable. One rotary drive source 10 is disposed on the base 8 and shafts 11 are rotatably disposed on both sides of the base 8. 10 and shaft 11 are connected by power transmission means 12,
One end of a link 13 is connected to the shaft 11, and the other end of the link 13 is connected below the load receiving portion 9.

An example of the power transmission means 12 will be described. Two first chain sprockets 14 are fixed to a drive shaft (not shown) of the rotary drive source 10, and the shaft 1
The first chain sprocket 15 is also fixed to the first chain sprocket 1, and the chains 16 are individually supported by the first chain sprocket 14 and the second chain sprocket 15. The two-chain sprocket 15 is transmitted to the shaft 11, and when the shaft 11 rotates, the link 13 also moves differently in the vertical direction depending on the rotation direction. That is, the load receiving portion 9 moves up and down depending on the rotation direction of the rotary drive source 10 and draws an arc of the link 13, thereby taking into account the horizontal movement.

The load receiving portion 9 is formed in a U-shaped cross section. The U-shaped opening 17 faces downward, and the other end of the link 13 is connected to the lower end of a leg 18 forming the opening 17. Then, the load receiving portion 9 moves up and down by the circular motion of the link 13. Further, a pallet receiver 19 for mounting a pallet (not shown) is fixed at four corners of the load receiving portion 9 slightly higher than the running surface.

The load receiving portion 9 is formed in a U-shaped cross section. The U-shaped opening 17 faces downward, and the other end of the link 13 is connected to the lower end of a leg 18 forming the opening 17. Then, in addition to the configuration in which the load receiving portion 9 moves up and down by the circular motion of the link 13, the second connection point B is disposed below the first connection point A between the shaft 11 and one end of the link 13.
By employing this configuration, the overall height of the storage and retrieval device 4 can be reduced. Therefore, it is not necessary to dig the pit 7 deep for the arrangement.

Referring to FIG. 4, another second loading / unloading device 4 of the present invention will be described. A table lifter 30 and a horizontally movable frame 32 are mounted on the upper surface of a table 31 which moves up and down. When the table lifter 30 is stored in the box 33 together with the gantry 32, a cam plate 35 having a cam groove 34 of a predetermined shape is fixed to both side surfaces of the box 33, and the cam follower 36 below the gantry 32 is When the gantry 32 is inserted into the cam groove 34 and rises, the cam follower 36 rolls in the cam groove 34,
The gantry 32 moves horizontally along the shape of the cam groove 34.

The box 33 is disposed in the pit, and is formed by combining L-shaped members.
Therefore, a space is formed on all side surfaces. A cam plate 35 having a cam groove 34 of a predetermined shape is fixed on both sides of the first side facing each other. The cam grooves 34 fix the cam plates 35 at the same positions.

The table lifter 30 is housed in the box 33. Stand 3 of table lifter 30
A cam follower 36 is rotatably mounted on the lower end of a bracket 37 that hangs down on both sides at the center of the lower part of 2. The cam follower 36 is inserted into the cam groove 34 and the table 31
When the table 31 moves up and down, the table 31 follows the shape of the cam groove 34.
The gantry 32 movably mounted on the upper surface of the device moves up and down and moves horizontally.

The table 31 of the table lifter 30 is
It is moved up and down by lifting means (not shown). The table 3
A rectangular parallelepiped member 38 serving as a pair of linear guide rails is fixed in the longitudinal direction of the upper surface of the table 31 along the shape of the cam groove 34 when the vertical movement 1 moves up and down. The guide member 39 for inserting the
It is fixed to the bottom of. The gantry 9 can be moved linearly by the rectangular parallelepiped member 38.

The gantry 32 has a U-shaped cross section, and has guide members 39 serving as guides for placing a pallet at four corners on the top of a pair of side walls located in the longitudinal direction.

[0017]

The present invention has a structure as described above. When the load receiving portion or the gantry is raised, the load receiving portion or the gantry is brought close to the stacker crane side, and when the transfer of the load is performed by another transfer device. In addition, by locating in a direction away from the stacker crane, the worker can work at a position far from the stacker crane, so that the worker can work with peace of mind, and the effect of improving work efficiency can be obtained.
