Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to an automated warehouse.

[0002]

[Prior art]

 The following are known as conventional automatic warehouses of this type. That is, a rack device having a large number of article storage shelves up and down, left and right, a stacker crane that is provided in front of the rack device so as to be movable left and right, and a conveyance direction arranged laterally of the rack device in the left and right direction. And a transfer conveyor (in this specification, the transfer-in / out conveyor means a function of at least one of a transfer-in conveyor and a transfer-out conveyor). It is known to have a traveling carriage, an elevating stand that can be raised and lowered by a mast provided on the traveling carriage, and a slide fork that is slidably mounted on the elevating stand in the front and rear directions. There is. The slide fork carries out the operations of projecting the article downward, lifting the article by raising the lift table, and retracting the article to the lift table side to pull the article into the lift table, and the reverse operation to store the article. Items can be dropped on shelves.

[0003]

[Disadvantages of the prior art]

 The conventional automatic warehouse has the following drawbacks. That is, in order for the slide fork to receive the article from the carry-in / out conveyor, or conversely to unload the article from the slide fork to the carry-in / out conveyor, an article lifter or an article unloader is installed at the article transfer station at the end of the carry-in / out conveyor. It had the drawback that it had to be provided. The article lifting machine forms a fork insertion gap between the transport surface of the loading / unloading conveyor and the bottom surface of the article by lifting the loading / unloading conveyor. On the other hand, the article unloading machine receives an article from the slide fork at a raised position, and then lowers the article to the loading / unloading conveyor.

[0004]

[Means for eliminating the above drawbacks]

 This invention adopts the following means in order to solve the above-mentioned drawbacks. The invention of claim 1 is provided with a rack device having a large number of article storage shelves, a stacker crane provided on the front of the rack device so as to be movable left and right, and a lift table of the stacker crane provided so as to be slidable back and forth. The drive conveyor has a transport direction directed to the left and right, and the carry-in / out conveyor having the drive direction fitted to the side of the rack device to form a space into which the drive conveyor fits There is something.

[0005]

[Function of the device]

 The invention of claim 1 has the following effects. The drive conveyor, which is installed on the stacker crane so that it can move back and forth, and whose transport direction is left and right, can transfer articles to and from the loading and unloading conveyor without using an article lifting machine or an article unloading machine. .

[0006]

【Example】

 The present invention will be described below based on an embodiment shown in the drawings. In this specification, the front means the lower side of FIG. 1, the rear means the upper side of FIG. 1, the left means the left side of FIG. 1, and the right means the right side of FIG.

A pair of front and rear rack devices 1 are erected on the floor so as to open the stacker crane passage 13. The rack device 1 includes a large number of front columns 2 arranged at right and left at predetermined intervals, rear columns 2 arranged behind the front columns 2 with a predetermined space therebetween, and the front and rear columns. 2 has a large number of article support members 4 provided therein, and a pair of left and right article support members 4 opposed to each other without the support columns 2 constitute an article storage shelf 3. Between the pair of left and right article support members 4 is a conveyor passage gap 5 that allows the drive conveyor 21 described later to move in the vertical direction. The access ports 6 of the article storage shelves 3 of the front and rear rack devices 1 face each other.

A space 9 into which a drive conveyor 21 to be described later is fitted is formed on the right side of the rear rack device 1, and a storage conveyor 10 having a conveyance direction oriented in the left-right direction is arranged, and the front rack device 1 is arranged. A space 9 into which a drive conveyor 21 to be described later is fitted is formed on the right side of, and a delivery conveyor 11 having a transport direction directed to the left and right is arranged. A drive roller conveyor is generally used for both the storage conveyor 10 and the storage conveyor 11.

A pair of upper and lower guide rails 14 are arranged in the stacker crane passage 13 so that the longitudinal direction thereof is oriented in the left-right direction, and the stacker crane 16 is guided by these guide rails 14 so as to be movable left and right. ing. The stacker crane 16 includes a traveling carriage 17, an elevating stand 19 that is vertically movable on a mast 18 provided on the traveling carriage 17, and a horizontal slide in the front-rear direction due to a well-known forward / backward movement mechanism of the elevating stand 19. It has a slide fork 20 freely provided, and a drive conveyor 21 provided on the slide fork 20 and capable of forward / reverse drive with the conveying direction directed to the left and right. The drive conveyor 21 carries out the operations of projecting the article W downward, lifting the article W by raising the lift table 19 and retracting the article W to the lift table 19 side, and pulling the article W into the lift table 19. By the reverse operation, the article W 1 can be dropped onto the article storage shelf 3. That is, when the article W is taken out from the article storage shelf 3 or stored in the article storage shelf 3, the drive conveyor 21 merely acts as a table for supporting the article W. On the other hand, the drive conveyor 21 is fitted in the space 9 and receives the article W from the storage conveyor 10 or the transfer conveyor 11 while the transport surface of the storage conveyor 10 and the transport surface of the drive conveyor 21 are flush with each other. When the article W is carried out to the delivery conveyor 11 in a state where the surface and the transport surface of the drive conveyor 21 are flush with each other, it acts as a conveyor.

A modification is shown in FIG. In FIG. 3, the slide fork 20 is provided with a horizontal base 24, and on the horizontal base 24, a free roller conveyor 26 having a conveyance direction oriented in the left-right direction is tilted leftward or rightward between the left and right standing walls 25. It is set freely. The free roller conveyor 26 can tilt the conveying surface to the left or right by operating either the left or right fluid pressure cylinder 27. A stopper 28 is provided at the left end of the free roller conveyor 26. It should be noted that, in order to prevent the stopper 28 from colliding with or interfering with the article support member 4 when the article W is delivered to and from the article storage shelf 3, the article support member 4 has a notch that allows the stopper 28 to move up and down. Are formed. When receiving the article W from the warehousing conveyor 10, the freeroller conveyor 26 is fitted into the space 9 so that the carrying surface of the freeroller conveyor 26 is located below the carrying surface of the warehousing conveyor 10, and then the freeroller conveyor 26 After the right end of the carrying surface is connected to the left end of the carrying surface of the storage conveyor 10, the article W is sent to the free roller conveyor 26 and placed on the free roller conveyor 26. After that, the free roller conveyor 26 is raised to the left end and becomes horizontal. On the other hand, when carrying out the article W to the delivery conveyor 11, the free roller conveyor 26 is fitted into the space 9 by making the transport surface of the free roller conveyor 26 flush with the transport surface of the delivery conveyor 11, and then the free roller The article W is carried out to the delivery conveyor 11 by raising the left end of the conveyor 26. After that, the free roller conveyor 26 becomes horizontal.
