Description

[Detailed description of the invention] Industrial field of application The present invention is an automated warehouse in which loading and unloading devices can automatically carry out loading and unloading of goods to and from shelves. It is related to jigs.

Prior Art The above-mentioned automated warehouse consists of a shelf in which a plurality of partitioned storage spaces are horizontally formed with arms for supporting loads on the left and right sides, and a shelf that is movable along the front surface of the shelf and can be moved up and down as well as moved in and out laterally. It consists of a loading/unloading device with a fork. By the way, the fixed position of the loading/unloading device in such an automated warehouse is important, and if this is disturbed, the forks will move in and out of the center of the compartment storage space, making it difficult to maintain a safe and stable storage space. Loading/unloading work cannot be carried out. Therefore, in the past, the worker moved a fork corresponding to the divided storage space, measured the gap between the fork and the arms on both sides, and inched the loading/unloading device several times to make the amount of gap on both sides equal. By doing so, the fixed position was set.

Problems that the invention aims to solve According to the conventional method described above, it is very dangerous because the worker stands on the fork to take measurements, and the worker inclines the fork. Settings cannot be made.

The purpose of the present invention is to provide a fixed position setting jig that allows a worker to take measurements without having to get on the fork, and to efficiently perform inching travel based on the measured values.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a fixed position setting jig for a loading/unloading device in an automated warehouse. A pair of rack rails that can move forward and backward in the width direction are provided in the length direction of the fork, and a drive device that moves in and out in conjunction with these rack rails is provided. An interlocking movement amount detection device is provided.

According to the configuration of the present invention, the rack rails are attached to the fork via the base plate, and the detection value is set to, for example, "0" when both rack rails are moved in and out the most, and the target compartment storage space is first detected. Stop the loading/unloading device with the fork facing the Next, the fork is moved up and down so that the contact portion is located at the height level of the arm, and then the fork is moved into the divided storage space. Next, both ejection/retraction drive devices are operated to cause both rack rails to protrude and move in opposite directions. These protruding movements are performed until the abutting portion abuts the corresponding arm. At this time, the amount of protrusion (amount of movement) is detected by a detection device, and the final amount of movement can be detected by the abutting portion coming into contact with the arm. Both detected values are compared, and 1/2 of the difference becomes the inching amount. After both rack rails are moved in and out, the loading/unloading device is moved by the amount of inching described above. This allows the loading/unloading device to be stopped at the correct position, but for confirmation, both rack rails are moved out again and the amounts of movement of both are detected and compared. After stopping at the correct position in this manner, the device to be detected is attached to a shelf, floor, etc. in accordance with the stop detector provided in the loading/unloading device, and the fixed position is set.

By meshing the rack rails 22A, 22B with the rack rails 22A, 22B, the movement amount of the rack rails 22A, 22B is counted and detected. A gap display device 31 is removably disposed in the control section 16, and this gap display device 31 is connected to the movement amount detection devices 28A and 28B via a cable 32. Reference numeral 34 denotes a stop detector on the traveling machine base 10 of the loading/unloading device 7, which is composed of, for example, a phototube device.
Reference numeral 35 indicates a detection target that can be freely attached to the floor rail 8 side.

Next, the fixed position setting work in the above embodiment will be explained.

First, the fixed position setting jig 18 is set on the fork 13. This is done by fitting the base plate 19 onto the intermediate portion of the primary 13A in the longitudinal direction, fixing it by tightening the bolts 20, and fixing it by tightening the bolts 20.
The gap display device 31 may be disposed in the gap display device 31, and the cable 32 is connected at this time. Then, the values detected by the detection devices 28A, 28B when both the rack rails 22A, 22B are moved in and out the most are set so that the display on the gap display device 31 is, for example, "0". In this state, the loading/unloading device 7 is moved and stopped in correspondence with the target compartment storage space 6, and then the elevating table 12 is raised and lowered to make the fork 13 face the target compartment storage space 6. At this time, the lifting movement is performed at the contact portion 2 at the height level of the arm 5.
3A and 23B are located. Then, the fork 13 is moved to protrude, and the primary 13A is moved into the divided storage space 6. Next, the motors 24A, 2 of both egress and retraction drive devices 33A, 33B
4B to cause both rack rails 22A, 22B to protrude in opposite directions via pinions 30A, 30B. These protruding movements are caused by the contact portion 23
This is continued until A and 23B come into contact with the corresponding arm 5. At that time, since the pinions 30A and 30B rotate as they protrude (move), the input shaft 29
The detection devices 28A and 28B perform count detection via A and 29B, and this is displayed on the gap display device 31. Therefore, the abutting portions 23A, 23 on the arm 5
By contacting B, the final amount of movement can be detected and displayed. Both detected values are compared, and 1/2 of the difference becomes the inching amount (correction amount). After performing the above-mentioned detection, the egress/egress drive device 3
By the reverse operation of 3A and 33B, both rack rails 2
2A and 22B are moved in and out. And passenger platform 17
The carry-in/out device 7 is moved forward or backward by the above-mentioned inching amount by the control operation by the operator above. This allows the loading/unloading device 7 to be stopped at the correct position, but for confirmation, both rack rails 22A, 22B are moved out again, and the amounts of movement of both rack rails 22A and 22B are detected and compared. After stopping at the correct position in this way, the fixed position can be set by attaching the detection target 35 to the shelf 1 or the floor side in accordance with the stop detector 34 provided on the loading/unloading device 7. finish.

Effects of the Invention According to the present invention having the above configuration, the rack rails are attached to the fork via the base plate, and the detection value is set to, for example, "0" when both rack rails are moved in and out the most, and the target section is first detected. After the fork is opposed to the storage space and the loading/unloading device is stopped, the fork is moved up and down so that the abutting part is located at the height level of the armrest, and the fork is plunged into the divided storage space. In this state, when both ejection/retraction drive devices are activated and both rack rails are moved to protrude in opposite directions until the abutment part contacts the arm, the amount of protrusion (amount of movement) can be detected by the detection device. .
Therefore, by comparing both detected values and running the loading/unloading device using 1/2 of the difference as the inching amount, the loading/unloading device can be stopped at the correct position. Thereafter, a fixed position can be set by attaching the detected device to a shelf, floor, etc. in accordance with the stop detector provided in the loading/unloading device.
As described above, according to the present invention, measurements can be taken without the operator riding on the fork, which is advantageous in terms of safety, and inching travel can be performed efficiently based on the measured values. Furthermore, since the present invention is mechanical and contact type, it is possible to freely and accurately measure the amount of protrusion even for shelves that combine compartment storage spaces with different distances between arms, and is highly reliable and removable. Therefore, it can be used to measure other shelves.
