Description

Article conveying equipment

Technical Field

The present invention relates to an article transport facility including a storage rack having a plurality of storage units for storing articles in a vertically aligned state, and a transport device for transporting the articles.

Background

As such article conveying apparatuses, for example, a structure described in japanese patent application laid-open No. 2018-091657 (patent document 1) is known. In the following description of the background art, bracketed reference numerals or names are those in the prior art documents. In the article conveying apparatus described in patent document 1, the conveying device (stacker crane 3) includes a lifting body (lifting table 13) that lifts up and down in the vertical direction, and a transfer device 14 that is supported by the lifting body and transfers articles between itself and the storage unit (storage unit 4).

In such an article transport facility, maintenance work for storing the rack (storage rack 2) may be required. Therefore, as a configuration in which an operator can ride on the lifting body of the conveyor, there is a case where the conveyor is used when performing maintenance work for storing the shelf. Specifically, in the case of performing maintenance work on the storage rack, there are cases where an operator rides on the lifting body in a state where the lifting body is lifted up to a height corresponding to a portion of the storage rack where the maintenance work is performed, the operator transfers from the lifting body to the storage rack, or the operator performs maintenance work on the storage rack.

Disclosure of Invention

However, depending on the size of each part of the article transport facility, the distance between the lifting body and the storage rack may be large. In such a case, maintenance work for the storage rack while riding on the lifting body is difficult, and in addition, in the case of transferring from the lifting body to the storage rack, such transfer is difficult.

Therefore, when the distance between the lifting body and the storage rack is large, it is desirable to realize an article conveying apparatus capable of easily performing maintenance work of the storage rack by the conveying device.

An article conveying apparatus according to the present disclosure includes: a storage rack having a plurality of storage units for storing articles in a vertically aligned state; and a conveying device for conveying the articles; the direction in which the storage rack and the conveying device are arranged in the vertical direction as viewed in the vertical direction is defined as the 1 st direction, the direction orthogonal to the 1 st direction as viewed in the vertical direction is defined as the 2 nd direction, and the side of the 1 st direction on which the storage rack is located with respect to the conveying device is defined as the 1 st direction 1 st side; the conveying device comprises a lifting body which is lifted up and down along the vertical direction, a transfer device which is supported by the lifting body and transfers articles between the self and the storage part, and a platform which can be detached from the lifting body and can be ridden by an operator; the lifting device is provided with a mounting part capable of mounting the platform on at least one side of the 2 nd direction relative to the transfer device; the table includes a mounting portion mounted on the mounting portion, and a protruding portion protruding toward the 1 st direction 1 st side from an end portion of the lifting body on the 1 st direction 1 st side; the mounting portion includes a plurality of fixing portions for fixing the stage to the mounting portion.

According to this feature, since the table is configured to be detachable from the lifting body, when performing maintenance work for storing the shelf, the operator can easily perform maintenance work for storing the shelf by mounting the table on the lifting body. On the other hand, when the article is conveyed by the conveying device, the table is separated from the lifting body, so that the transfer device or the article can be prevented from interfering with the table when the article is transferred by the transfer device. Thus, structural and operational constraints of the transfer device and the conveying device due to the provision of the table can be reduced.

Further, since the table is provided with the protruding portion protruding from the 1 st side end portion of the lifting body in the 1 st direction to the 1 st side in the 1 st direction, the worker can get closer to the storage rack by riding on the protruding portion of the table than in the case of riding on the lifting body. Therefore, the maintenance work for the storage rack in the state where the operator sits on the table is easy, and the operator can easily transfer the storage rack from the table to the storage rack for the maintenance work. As described above, according to the present configuration, when the distance between the lifting body and the storage rack is large, maintenance work of the storage rack by the conveyor can be easily performed.

3. Summary of the above embodiments

The outline of the article transport apparatus described above will be described below.

The article conveying device is provided with: a storage rack having a plurality of storage units for storing articles in a vertically aligned state; and a conveying device for conveying the articles; the direction in which the storage rack and the conveying device are arranged in the vertical direction as viewed in the vertical direction is defined as the 1 st direction, the direction orthogonal to the 1 st direction as viewed in the vertical direction is defined as the 2 nd direction, and the side of the 1 st direction on which the storage rack is located with respect to the conveying device is defined as the 1 st direction 1 st side; the conveying device comprises a lifting body which is lifted up and down along the vertical direction, a transfer device which is supported by the lifting body and transfers articles between the self and the storage part, and a platform which can be detached from the lifting body and can be ridden by an operator; the lifting device is provided with a mounting part capable of mounting the platform on at least one side of the 2 nd direction relative to the transfer device; the table includes a mounting portion mounted on the mounting portion, and a protruding portion protruding toward the 1 st direction 1 st side from an end portion of the lifting body on the 1 st direction 1 st side; the mounting portion includes a plurality of fixing portions for fixing the stage to the mounting portion.

According to this configuration, since the table is configured to be detachable from the lifting body, when performing maintenance work for storing the shelf, the operator can easily perform maintenance work for storing the shelf by mounting the table on the lifting body. On the other hand, when the article is conveyed by the conveying device, the table is separated from the lifting body, so that the transfer device or the article can be prevented from interfering with the table when the article is transferred by the transfer device. Thus, structural and operational constraints of the transfer device and the conveying device due to the provision of the table can be reduced.

Further, since the table is provided with the protruding portion protruding from the 1 st side end portion of the lifting body in the 1 st direction to the 1 st side in the 1 st direction, the worker can get closer to the storage rack by riding on the protruding portion of the table than in the case of riding on the lifting body. Therefore, the maintenance work for the storage rack in the state where the operator sits on the table is easy, and the operator can easily transfer the storage rack from the table to the storage rack for the maintenance work. As described above, according to the present configuration, when the distance between the lifting body and the storage rack is large, maintenance work of the storage rack by the conveyor can be easily performed.

Here, it is preferable that the stand includes a pillar portion connected to the elevating body; the pillar portion includes a1 st coupling portion coupled to the protruding portion and a2 nd coupling portion coupled to a lower portion of the lifting body.

According to this configuration, the 1 st connection portion is connected to the protruding portion of the table, and the 2 nd connection portion is connected to the lower portion of the lifting body, so that the protruding portion can be supported from below by the pillar portion while sandwiching the pillar portion between the protruding portion and the lower portion of the lifting body. Therefore, the downward deflection of the protruding portion of the table can be suppressed when the operator gets on the protruding portion.

Further, it is preferable that the 1 st direction side is set to be the 1 st direction 2 nd side opposite to the 1 st direction 1 st side; the table further includes a clamping portion connected to the mounting portion; the clamping portion is configured to extend in the up-down direction on the 1 st direction 2 nd side relative to the lifting body, and is configured to clamp the lifting body from both sides in the up-down direction.

According to this configuration, the lifting body can be held by the holding portions on the 1 st and 2 nd sides of the lifting body from both sides in the vertical direction, and the table can be fixed to the lifting body. Therefore, when the operator gets on the protruding portion of the table, the end portion on the 1 st direction 2 nd side of the table can be prevented from moving upward with respect to the lifting body.

Further, it is preferable that the plurality of fixing portions are provided at positions corresponding to insertion holes formed in advance in the elevating body; the fixing portions are fixed to the mounting portion by fastening members inserted into the insertion holes, respectively.

According to this configuration, the table is fixed to the mounting portion by fastening and fixing, so that the table can be easily attached to and detached from the lifting body. Further, by fixing the stage to the mounting portion by the insertion portion formed in advance in the elevating body, the necessity of forming a new insertion hole or the like in the elevating body for fixing the stage can be reduced.

Further, it is preferable that the stage includes a fence that restricts movement of an operator on the protruding portion at an end of the protruding portion on at least one side in the 2 nd direction or on at least one side in the 2 nd direction with respect to the protruding portion.

According to this configuration, the movement of the worker from the end portion on the 2 nd side of the protruding portion to the one side of the 2 nd direction can be restricted by the fence. Further, according to the present structure, the worker on the protruding portion can support the body with the fence. Therefore, the worker can be appropriately prevented from falling off the protruding portion.

Further, it is preferable that the protruding portion includes a riding surface on which an operator rides, and a rising portion provided at both ends of the riding surface in the 2 nd direction, the rising portion rising upward from the riding surface and extending continuously in the 1 st direction.

According to this configuration, the movement of the foot of the operator riding on the riding surface and the movement of the object placed on the riding surface are restricted by the ascending portion, so that the operator can be prevented from stepping on the foot from the riding surface or from dropping off the object placed on the riding surface.
