Abstract

PURPOSE:To employ a flexible rack arrangement so as to aim at enhancing the efficiency of workpiece storage by providing a control means for instructing and controlling the projection of arm bars from the side faces of support columns. CONSTITUTION:Arm bars 2 adapted to be retracted into and extended from support columns 1 in a workpiece storage rack under instructions from a controller are attached to the side surfaces of the support columns 1, being opposed to each other. Further, during introduction and delivery of workpieces a stacker crane which may be stopped at an arbitrary height under instructions of the controller is used. When workpieces 3 alone are stored, it is sufficient to extend all arm bars under instructions of a controller. if workpieces having different dimensions, such as workpieces 4, 5 are stored, it is sufficient to retracts arm bars 2 at positions where the workpieces 4, 5 are stored, into the support columns 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an automatic warehouse in a factory warehouse, distribution center, etc.

(Prior Art and Problems to be Solved by the Invention) Conventional automated warehouses have fixed workpiece storage racks, so the height of the racks must be set to match the maximum height of the workpieces. Therefore, when storing workpieces of different sizes, the utilization efficiency of the warehouse deteriorates, and the warehouse as a whole becomes large compared to the storage capacity. On the other hand, when trying to reduce the size of a warehouse, it was necessary to abandon the storage management of large workpieces in an automated warehouse.

The present invention has been made in view of the above reasons, and an object of the present invention is to provide an automatic warehouse that can easily improve workpiece storage efficiency.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the object of the present invention, a plurality of supports are arranged opposite to each other and constitute a work storage shelf.

It is characterized by comprising at least a plurality of movable arms arranged opposite to each other on the side surfaces of these columns, and a control means for commanding and controlling the protrusion of these arms from the side surfaces of the columns. do.

(Function) With this configuration, it becomes possible to control the position of the arm that protrudes from the side surface of the support, and it becomes possible to adopt a flexible shelf configuration.

(Example) An example of the present invention will be described with reference to FIGS. 1 and 2.

In FIG. 1, arms 2 are attached to the sides of a support 1 of a work storage shelf in opposition to each other, and are moved in and out of the support according to instructions from a controller (not shown). In addition, a stacker crane that can be stopped at any height according to instructions from a controller is used for loading and unloading workpieces.

With the above configuration, if only workpieces (small) 3 are to be stored, all the arms need to be brought out using the controller, as shown in Figure 2, and workpieces (medium) 4. When workpieces of different sizes are mixed together, such as workpiece (large) 5, the arm in the place where workpieces 4 and 5 are stored can be stored within the support.

According to this embodiment, a shelf of any height can be created at any position by changing the position where the arms are stored, so a flexible shelf configuration is adopted that is not restricted by the height of the workpiece. be able to.

(Other Embodiments) Next, another embodiment of the present invention will be described with reference to FIG.

In Fig. 3, the pallet 6 is larger than the spacing between the opposing arms, the width of the workpieces 3, 4.5 is smaller than the spacing between the arms, and the stacker crane controlled by the controller can be moved at any arm position. Can be stopped.

In the above configuration, a workpiece of any height can be stored at any position by controlling the stanker crane.

〔Effect of the invention〕

According to the present invention, it is possible to employ a flexible shelf configuration that is not restricted by the height of the workpieces, and it is possible to provide an automatic warehouse that can easily improve workpiece storage efficiency.

Claims (1)

[Claims] A plurality of columns forming a work storage shelf are arranged opposite to each other, a plurality of movable arms are arranged opposite to each other on the sides of these columns, and these arms protrude from the side surfaces of the columns. An automatic warehouse comprising at least a control means for command and control.
