Abstract

(57) [Summary] [Purpose] To reduce the dead space on the side of the stacker crane, and to enable operation of the stacker crane from the top of the maintenance platform. [Structure] An operation panel for raising and lowering the maintenance lifting platform 30 and operating the crane main body 22 is provided in the maintenance lifting platform 30 provided on the crane main body 22 so as to be able to rise and fall freely.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a stack system for loading and unloading goods such as luggage into storage shelves etc. in warehouses etc. Regarding Kakuran.

0002

[Conventional technology]

Conventionally, items were stored in storage shelves using slide forks installed on the transport platform. Or as a stacker crane for unloading, elevating platforms for transportation, sliding forks, etc. Equipment that has a maintenance lifting platform that goes up and down parallel to the transportation lifting platform in order to perform maintenance. It has been known. This stacker crane is equipped with a For this purpose, an operation panel is provided, and these maintenance platforms and operation panels are usually They are placed completely separately on both sides of the lane body.

0003

[Problem that the idea aims to solve]

The conventional stacker crane described above has a maintenance lifting platform and an operation panel that are completely separate. In order to install these, it is necessary to secure space on both sides of the lifting platform. However, there was a problem in that the widthwise dimension of the stacker crane increased. Also, the maintenance lift The platform is only equipped with a lifting operation device, and a worker on the maintenance platform can It was not possible to move the crane freely. This invention has a small width dimension, little dead space, and a lift platform for maintenance. A stacker crane that allows you to operate the stacker crane even at the top. The purpose is to provide

0004

[Means to solve the problem]

The stacker crane according to the present invention is a maintenance crane that is installed on the crane body so that it can be raised and lowered freely. It is housed inside the maintenance lifting platform and is used for operation and maintenance of the crane. It is characterized by being equipped with an operation panel for raising and lowering the guard lift platform.

【Example】

The present invention will be explained below with reference to the illustrated embodiments. The stacker crane 10 is provided so as to be movable in the left-right direction in FIG. It is moved by a lane driving mechanism. The stacker crane 10 is installed inside the warehouse. A transport platform 20 that can be raised and lowered is installed on a storage shelf (not shown) provided in multiple stages downward. A slide fork that is movably supported in the horizontal direction on the transport platform 20 The baggage 11 is entered into or taken out of the warehouse by means of the check 24. These transportation lifting platforms 20 and and the slide fork 24 are normally installed at the main operation panel (see figure) provided at the entrance of the warehouse. (not shown) is controlled via an optical communication system.

[0006] The transport platform 20 is supported by the crane body 21 so as to be able to rise and fall, and is supported by a crane (not shown). It is raised and lowered by a lane raising and lowering mechanism. The crane body 21 is placed on the warehouse floor for a predetermined distance. A horizontal frame 23 is joined to the upper ends of two vertical frames 22 that are erected at a distance. It is formed into a portal shape as a whole. On this conveyance lifting platform 20, there is a slide frame. A fork 24 is supported so as to be movable in the horizontal direction toward the storage shelf. slide photo The arc 24 is driven by a motor (not shown) fixed on the transport platform 20. Then, the luggage 11 is loaded into or taken out of the storage shelf.

[0007] The maintenance lifting platform 30 has a rectangular parallelepiped shape with a space inside which a person can sit. It consists of a box. This maintenance lifting platform 30 is one vertical frame of the crane main body 21. 22 so that it can be raised and lowered, and is raised and lowered by a cage raising and lowering mechanism (not shown). . Inside the maintenance lifting platform 30, there is a crane operating mechanism, a crane lifting mechanism, and a cage. An operation panel is provided to operate each stage elevation mechanism. Operate this control panel By doing so, the operator can move the crane main body 2 while remaining on the maintenance lifting platform 30. 1 to a predetermined location, raise and lower the maintenance lifting platform 30, and The luggage 11 can be stored in or taken out of the storage rack.

[0008] Therefore, for example, if a load collapses while the transport platform 20 is raised, In this case, the operator operates the operation panel while remaining on the maintenance elevator platform 30 to raise the cage. Activate the lowering mechanism and raise the maintenance elevator platform 30 to the position where the transportation elevator platform 20 has stopped. raise When the transport platform 20 reaches the stopped position, the source of the load collapse etc. After resolving the problem, operate the operation panel again to raise and lower the transport platform 20 and the slide frame. arc 24 can be activated.

[0009] As described above, according to the above embodiment, operations can be performed using the operation panel in the maintenance elevator platform 30. At the same time, one operator can carry in or out the cargo 11, maintain it, inspect it, etc. Ru. In addition, compared to the case where the operation panel is provided separately from the maintenance lifting platform 30, the stacker crane The dead space on the sides of the lane 10 can be reduced.

0010

[Effect of the idea]

As described above, according to the present invention, the dead space on the side of the stacker crane is reduced. Operate the stacker crane even on the maintenance lifting platform. This has the effect of making it possible.
