Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an article storage shelf component such as a rack device of an automated warehouse.

[0002]

[Prior art]

 Heretofore, the following members have been known as this type of article storage shelf constituent member. That is, the article storage shelf constituent members are provided on the front and rear columns on the left side and the front and rear columns on the right side at predetermined intervals in the height direction so as to face each other. It is known to have an arm and an article support bar which is stopped at the tip of the arm.

[0003]

[Disadvantages of the prior art]

 The conventional article storage shelf constituent members have the following drawbacks. That is, because the upper surface of the arm and the upper surface of the article support bar that is stopped at the tip of the arm are flush with each other, that is, because the upper surfaces of the article storage shelf constituent members are flat, in the event of an earthquake, etc. When the articles placed on the left and right article storage shelf components are displaced from the set position in the front-rear direction, and when the articles are not exposed, the articles may protrude toward the aisle side of the stacker crane, and troubles such as blocking the stacker crane from running may occur. I was afraid.

[0004]

[Means for eliminating the above drawbacks]

 This invention adopts the following means in order to solve the above-mentioned drawbacks. This invention has front and rear arms provided on front and rear columns, and article support bars that are fixed to the lower surface of the arms, and the surfaces of the front and rear arms facing each other face upward. It is an inclined guide surface that expands with each other.

[0005]

[Function of the device]

 This device has the following actions. Since the article supporting bar is fixed to the lower surface of the arm, the articles placed on the article supporting bar can be prevented from shifting in the front-rear direction by the arm located above the article supporting bar. Further, since the surfaces of the front and rear arms facing each other are inclined guide surfaces that expand upward from each other, the articles placed on the article support bars can be moved forward and backward by the guiding action of the inclined guide surfaces. You can guide and smoothly place the article on the support bar.

【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 10. 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 storage shelf constituent members 4 provided at predetermined intervals in the height direction, and the article storage shelves 3 are formed by a pair of left and right article storage shelf constituent members 4 that face each other without interposing the columns 2. It is configured. A fork passage gap 5 is provided between the pair of left and right article storage shelf constituent members 4 to allow the vertical movement of a slide fork 17, which will be described later. The access ports 6 of the article storage shelves 3 of the front and rear rack devices 1 face each other.

The article storage shelf constituent member 4 includes front and rear arms 21 each having a triangular cross section, which are provided on the front and rear columns 2, and an article support bar 22 having a rectangular cross section which is attached to the lower surface of the arm 21. Have The surfaces of the front and rear arms 21 that face each other serve as inclined guide surfaces 23 that expand toward each other upward.

The articles W placed on the pallet P are stored together with the pallet P in the article storage shelf 3. The length L1 between the lower edges of the inclined guide surfaces 23 of the front and rear arms 21 is equal to or slightly longer than the front and rear length L2 of the pallet P. With such a configuration, when the pallet P on which the article W is placed is stored in the article storage rack 3, the pallet P is guided by the front and rear inclined guide surfaces 23 even if the position of the pallet P is slightly displaced forward and backward. Can be smoothly placed on the article support bar 22. However, the length L1 between the lower edges of the inclined guide surfaces 23 of the front and rear arms 21 may be longer than the front and rear length L2 of the pellet P.

On the left side of the rack device 1, there is provided a loading / unloading roller conveyor 8 whose carrying direction is left and right. A known article elevator (not shown) is provided on the rack device 1 side of the loading / unloading roller conveyor 8. This article elevator is provided with a lift table that can be lifted and lowered by a known lift device below the rollers of the loading / unloading roller conveyor 8, and a pair of stands located between the rollers of the loading / unloading roller conveyor 8. It has a support frame. This article lifter lifts the pallet P by the support frame to form a fork insertion gap between the transfer surface of the loading / unloading roller conveyor 8 and the lower surface of the pallet P, and the support frame in the raised position. It receives the pallet P from the slide fork 17, and then lowers the pallet P to the loading / unloading roller conveyor 8 to lower the pallet P.

A pair of upper and lower guide rails 11 are arranged in the stacker crane passage 10 so that the longitudinal direction thereof is oriented in the left-right direction, and the stacker crane 13 is guided by these guide rails 11 so as to be movable left and right. The stacker crane 13 includes a traveling carriage 14, an elevating stand 16 which is vertically moved by a mast 15 provided on the traveling carriage 14, and a forward / backward movement mechanism known to the elevating stand 16 in the front-back direction. The slide fork 17 is provided so as to be horizontally slidable. As is well known, the sliding fork 17 projects the pallet P downward, lifts the pallet P up and down to lift the pallet P, and moves the pallet P back and forth to move the pallet P up and down. Then, the pallet P can be lowered onto the article storage shelf 3 or the like by the reverse operation.

[0012]

[Effect of device]

 The present invention has the following effects due to the above-described configuration. Since the article support bar is attached to the lower surface of the arm, the article placed on the article support bar can be prevented from shifting in the front-rear direction by the arm located above the article support bar. The surfaces of the front and rear arms that face each other are inclined guide surfaces that expand toward each other upward, so that the guide function of the inclined guide surface guides the articles placed on the article support bars back and forth. It can be smoothly placed on the article support bar.
