Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading / unloading device for an automatic warehouse which is installed in, for example, a factory, is supported and guided by a floor rail, and can travel on a fixed path in front of a shelf.

[0002]

2. Description of the Related Art In an automatic warehouse comprising shelves and a loading / unloading device, a structure shown in FIG. 5 is provided as a lower frame of the loading / unloading device. That is, the lower frame 50 of the loading / unloading device is a pair of left and right channel members.
51 and a pair of front and rear end members 52 fitted between the ends of the channel members 51 and integrated with rivets or bolts. Both end members 52 are post mounting seats that face upward.
53 is integrally formed, and the post is attached to this post mounting seat 53.
54 is erected and integrated with rivets and bolts.

Then, one of the end members 52 is integrally formed with an upward drive driving device mounting seat 55 and a rearward (forward) driving driving device mounting seat 56. An elevating drive device 57 interlocking with an elevating body is attached to the elevating drive device mounting seat 55 with a bolt or the like. In addition, the traveling drive device mounting seat
A bracket 60 having a drive wheel 58 and a traveling drive device 59 is attached to 56 with bolts or the like.

[0004]

The above-mentioned end member 52 is manufactured by casting, and therefore, the post mounting seat.
If the 53, the elevating drive device mounting seat 55, and the traveling drive device mounting seat 56 are made as a unit by casting, the seat 5
As a result, the passage of hot water to the portions 3, 55, and 56 becomes poor, and a good end member 52 cannot be manufactured. In addition, a seat integrally formed with the end member 52
Since 53, 55, and 56 have a constant shape, the channel material 51
It is not possible to easily attach another type of lifting drive device 57 or traveling drive device 59 after assembling the same as above.

It is an object of the present invention to provide an automatic warehouse loading / unloading device in which end members can always be favorably manufactured, and another type of lifting drive device can be easily replaced.

[0006]

In order to achieve the above object, an automatic warehouse loading / unloading apparatus according to the present invention is a loading / unloading apparatus which is supported and guided by a floor rail and can travel on a fixed path in front of a shelf. And a post standing upright from the lower frame, and an elevating body having a retractable device that is guided to the side of the post and provided with a detachable mounting seat for the lower frame. In addition, an elevating and lowering drive device that interlocks with the elevating and lowering body is provided.

[0007]

According to the structure of the present invention, in the manufacturing factory,
A plurality of types of mounting seats and lifting drives are prepared in advance, and when an order is placed, the mounting seats are attached to the lower frame assembled according to the model to be handled, and further to the mounting seats. And a lifting drive is attached. Therefore, the end member on the lower frame side can be manufactured without forming the lifting drive device mounting seat, and can be replaced with another lifting drive device via the mounting seat.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. As shown in FIGS. 3 and 4, the frame-shaped shelf 1
Forms a plurality of storage sections 2 in the vertical direction and the horizontal direction, and each storage section 2 is configured to support a load 3 (directly or via a pallet) via arms. The shelves 1 are arranged side by side with a passage 4, and in the passage 4, a loading / unloading device 10 is arranged which can travel on a fixed path 5 in front of the shelves 1.

The loading / unloading device 10 includes a lower frame 11
And a pair of front and rear posts erected from this lower frame 11.
12 and the upper frame that connects the upper ends of these posts 12
13 and 13 form a traveling body. And both posts
An elevating body 14 is arranged between the two 12, and an evacuation tool (fork) 16 is arranged on the elevating body 14 so as to be able to move in and out of the storage part 2 and the like by the operation of the retracting device 15. The lower frame 11 has drive wheels 17 and driven wheels 18 which are rollable on the floor rail 6 and which are distributed forward and backward, and the upper frame 13 is a guide roller guided by the ceiling rail 7.
Has 19.

As shown in FIGS. 1 and 2, the lower frame 11 is fitted between a pair of left and right channel members 20, and is fitted between the end portions of the channel members 20 and integrated with a fixing member 21 such as a rivet or a bolt. It is composed of a pair of front and rear end members 22, 23. Both end members 22 and 23 are made of cast metal, and an upward post mounting seat 24 is integrally formed.
The post 12 is erected on 24 and is integrated with a fixture 25 such as a rivet or a bolt.

A lateral traveling drive device mounting seat 26 is integrally formed on one end member 22, and the traveling drive device 27 is fixed to the traveling drive device mounting seat 26 by a fixture 28 such as a rivet or a bolt. It is integrated. The traveling drive device 27 includes a motor 29 and a speed reducer 30, and an output shaft from the speed reducer 30 is linked to the drive wheels 17.

A mounting seat 31 is detachably attached to the lower frame 11. That is, the mounting seat 31 is made of cast metal, and has a lower side connecting portion 32 that is laterally or downwardly formed in the lower portion thereof, and an upper connecting portion 33 that is upward facing is formed in the upper portion thereof. Then, the mounting seat 31 is detachably mounted via a fixture 34 such as a bolt after the lower coupling portion 32 is applied to the side surface or the upper surface of the end member 22.
