Abstract

PURPOSE:To reduce the pitch between wheels and miniaturize a device by elastically pressing pushing wheel bodies to a ceiling rail on the top end side of the pillar of the putting in/out device of an automatic warehouse and applying the reaction thereof to wheels on the lower portion to increase wheel weight. CONSTITUTION:At the time of operating warehouse equipment, a putting in/out device 10 is made travel in a passage to carry out the delivery of a load between a desired block housing space and a load handling place via the putting in/out device 10 by the combined action of the lifting up/down motion of a carriage 15 and the laterally advancing/retracting motion of a putting in/out member 16. In such an operating condition, a pair of front/rear pushing ring bodies 21A, 21B are pressed against the underside of a ceiling rail 8 by the elastic force of a spring, on the top end side of a pillar 14. Hence, the reaction thereof acts on both wheels 11, 12 side to be added to the self weight applied to the wheels 11, 12 side, increasing the wheel weight. Due to the increase in this wheel weight, the falling of the putting in/out device 10 can be prevented while even enabling the pitch P between the wheels to be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to applications installed indoors, for example, for storing various loads,
This relates to automated warehouses where storage is performed.

BACKGROUND OF THE INVENTION Conventionally, as a private warehouse consisting of shelves and a storage/retrieval system, an II structure has been proposed, for example, as disclosed in Japanese Patent Application Laid-Open No. 62-295807. In this conventional 4111 construction, the crane (unloading/unloading device) includes a traveling body that is supported and guided by a guide rail on the floor via traveling drive wheels and driven wheels, and one support that is erected from this traveling body. It is comprised of a guide wheel provided at the upper end of this support column and facing the side surface of the ceiling rail, a four-descent carriage guided by the support support, and a transfer tool provided on this elevating kittridge.

Problems to be Solved by the Invention According to the conventional 411 construction described above, the weight of the driven wheels decreases due to acceleration and deceleration during crane travel, and the crane tends to move along the track. Therefore, it is not possible to increase the acceleration/deceleration and speed of travel, and the efficiency of work cannot be improved. It is also conceivable to increase the pitch between the driving wheels and the driven wheels in order to prevent transfer, but this would increase the overall length of the crane and increase its size.

An object of the present invention is to provide a self-vehicle vehicle warehouse in which the wheel load can be increased without increasing the pitch between the wheels.

Means for Solving the Problems In order to achieve the above object, the self-help storehouse of the present invention is a great facility that has a shelf having a plurality of compartment storage spaces and a loading/unloading device that can freely run along the front surface of the shelf. In the above, the loading/unloading device includes a traveling body supported and guided via a plurality of wheels, and a pillar erected from the traveling body.
A carriage that is guided up and down by this support and has a loading/unloading tool that can move in and out in the lateral direction; a guide wheel that is attached to the top end of the support and faces the side surface of the ceiling rail; A pressing C-pull body is attached to the ceiling rail and can be elastically brought into contact with the lower surface of the ceiling rail.

Effects According to the configuration of the present invention, when the loading/unloading device is running, the front and back pressing on the upper end side of the column is caused by the wheel being elastically pressed against the lower surface of the ceiling rail, so that the reaction force is transferred to the lower wheel side. The above-mentioned reaction force is added to the dead weight (load) applied to the floor rail side, which can increase the wheel load of the wheels.

Example An embodiment of the present invention will be described below based on the drawings.

Reference numeral 1 refers to shelves arranged side by side with aisles 2, each consisting of vertical supports 3 installed in two rows horizontally at predetermined intervals, and armrests 4 installed between the vertical supports 3 facing each other in the front and rear. A plurality of partitioned storage spaces 5 having load supporting arms 4 on the left and right sides are formed in the vertical and horizontal directions. Each compartment storage space 5 can be stored using pallets or packets.
Alternatively, cargo can be stored directly. A cargo handling area is disposed outside one end of the l11, and this cargo handling area receives and transfers cargo to the outside via a conveyor device, a forklift truck, etc. Reference numeral 10 denotes a loading/unloading device disposed within the aisle 2 and capable of freely traveling on a fixed path 9 along the front surface of Ill and the cargo handling area, and is supported on the floor rail 7 via drive wheels 11 and conventional vehicle transport 12.

Next, the operation of the above embodiment will be explained.

During operation, the loading/unloading device e10 is run in the passage 2, and the lifting/lowering movement of the carriage 15 and the loading/unloading device 16 are performed.
This loading/unloading operation (transferring cargo between the intended partitioned storage space 5 and the cargo handling area via 10) is carried out in conjunction with the lateral movement of the loading/unloading system. In such an operating state, the pair of front and rear wheels on the upper end side of the column 14 are pressed against the wheel 21A.

213 is pressed against the lower surface 8b of the ceiling rail 8 by the elastic force of the springs 28A and 28B, the reaction force acts on both wheels 11 and 12, and the self weight (load) applied to these wheels 11 and 12 is reduced. ), which increases the wheel load. Due to this increase in wheel load, it is possible to prevent the loading/unloading device 10 from falling while reducing the inter-wheel pitch P.

Effects of the Invention According to the Mokubimei with the above configuration, when the loading/unloading device runs, the front and back pressure on the upper end side of the support is elastically pressed against the lower surface of the ceiling rail, so the reaction force is transferred to the lower side. The above-mentioned reaction force is added to the own weight (load Φ) on the floor rail side.
The wheel load can be increased. By increasing the wheel load, it is possible to shorten the pitch between the wheels and downsize the entire length, and it is also possible to increase the acceleration/deceleration and speed of travel to improve work efficiency, while also increasing the speed of loading and unloading. It can prevent falls.
