FIELD OF THE INVENTION This invention relates to improvements in automated warehouses.

[0002]

There are several forms in the automated warehouse BACKGROUND OF-0005], an automatic warehouse with them comprising a stacker crane, both sides or a number on one side across the travel path of the movable carrier, such as a stacker crane The storage shelves are arranged in a matrix in the vertical and horizontal directions so that luggage can be put in and taken out between the moving carriage and any storage shelves, and the back of each storage shelves is generally covered with a cover. It has become.

Incidentally, depending on the type of luggage to be stored in the storage rack, it may be necessary to inspect or adjust it again after storing it in the storage rack. However, in the conventional automated warehouse, the luggage stored in each storage rack can be taken out only by the moving carriage, so when carrying out such inspections and adjustments as to the luggage, the luggage is moved to the exit of the moving carriage. After taking out, perform inspection and other work,
Then, it is necessary to take the procedure of returning it to the original storage rack with the mobile trolley, which not only takes time for the inspection and adjustment work but also the mobile trolley during the inspection and adjustment. Since it had to be stopped, there was a problem that the efficiency of loading and unloading of automated warehouses was inefficient.

An object of the present invention is to solve this problem and improve the usability of the automatic warehouse.

[0005]

[0007]

[Advantageous Effects of the Invention] With this structure, the luggage stored in the storage rack provided with the manual outlet can be manually removed and used for inspection, adjustment, etc. without using a moving carriage. since it is possible to be returned by hand to the original storage shelf When you have finished, Ru can do the work of the inspection and adjustment of their luggage cleanly.

Further, since the luggage is pulled out to the side opposite to the traveling path of the moving carriage, it is not necessary to stop the moving carriage when performing work such as checking or adjusting the luggage, and it is possible to remove the luggage from a specific storage rack. Since it is possible to take out and put in and take out the luggage to and from other storage shelves at the same time by the moving cart, the efficiency of loading and unloading in the automatic warehouse does not decrease, and as a result, the usability of the automatic warehouse is improved. Can be significantly improved.

[0009] Also, create skilled in the art will not each time need to suffer to have the luggage when loading and unloading the luggage from the storage shelf, because may be performed out of the luggage by sliding move on the chute, the removal of luggage with a light force It can be done extremely easily. In this case, if the chute is configured to be flipped up and rotated toward the storage shelf, there is an advantage that the chute can be prevented from becoming an obstacle when not in use.

According to a second aspect of the present invention , the stopper has a roller shape.
Once formed, it can be loaded and unloaded smoothly.
Wear.

Further, according to the third aspect of the invention, when the load in the storage rack is transferred to the chute in a state of being raised and rotated about the lower end of the manual take-out port, the front end edge of the load is a guide body for pulling out. The baggage is
While moving around the lower end of the manual take-out port, it moves toward the chute.

In other words, the luggage automatically shifts to the chute only by pulling it while rotating around the lower end of the manual unloading port, and therefore, the manual unloading of the luggage is further facilitated. Can be done easily
It

Further, according to the structure of claim 4, it is possible to surely prevent the luggage stored in the storage rack from unexpectedly slipping out from the manual take-out port, and the luggage in the storage rack moves due to vibration or the like. Since the moving carriage stops when it goes out of the traveling path, it is possible to reliably prevent the moving carriage from colliding with luggage and ensure safety.

In this case, in order to take out the luggage from the manual take-out port, the trailing end of the luggage must be lifted above the stopper at the beginning of pulling out so that the luggage can go over the stopper. Therefore, a stopper and a sensor are simply provided. Otherwise, if the rear end of the luggage is excessively lifted too much and the luggage leans forward too much, the front end of the luggage will protrude into the traveling path of the moving carriage and the sensor will operate, causing the traveling of the moving carriage to stop. There is a risk.

[0015] However, when the height of the front end of the drawer guide body is constructed as claimed in claim 4, in pulling out <br/> originally luggage manually, towards the luggage travel path of the mobile carriage When tilting forward, the forward leaning posture of the luggage is regulated by the guide body for pulling out, and it is prevented from protruding to the front end of the luggage or the traveling path of the moving carriage, so the traveling of the moving carriage stops when manually pulling out the luggage. It can be prevented from doing.

Therefore, according to the structure of claim 4, it is possible to prevent the luggage in the storage rack from accidentally slipping out from the manual take-out port, and the luggage can be removed from the storage rack under the condition that the traveling of the movable carriage is ensured. Can be taken out very easily

In the embodiment, the sensor 21 is used for all the storage shelves 3
It is provided at the location. Needless to say, the sensor 21 is not limited to the photoelectric type, and various types of contact type or non-contact type can be used.

[0030] The lower portion of part of the manual eject hole 7 in each storage rack 3 positioned at the bottom, order to prevent the tray 4 from sliding from the manual eject hole 7 outside, roller-shaped stopper 22 is disposed Has been done. This stopper 2
2 is rotatably mounted on a first support shaft 24 between a pair of front and rear third brackets 23 protruding outward from the rear columns 15 adjacent to each other.

Further, the front and rear third brackets 23 are made to project more outward than the stopper 22, and a connecting rod 25 having a front and rear side plate 25a and having an inverted L-shaped cross section is provided between the front end portions of the front and rear third brackets 23. A second support shaft 26 is rotatably supported, and a chute 27 for slidably moving the tray 4 pulled out from the manual take-out port 7 is fixed to the connecting rod 25. Therefore, the chute 7 can be flipped up and rotated about the second support shaft 26. The chute 7 may be fixed to the hangar 2.

The chute 27 is formed in a gutter shape with an upward opening in cross section, and an edge plate 27a for stopping the tray 4 is provided at the tip thereof. Also, shoot 27

Is stuck.

As shown in FIG. 12, when the tray 4 is pulled out from the manual take-out port 7 as shown in FIG. 12, when the tray 4 is placed on the stopper 22, it is tilted backward as shown by the solid line. The height and angle are set so that the upper end of the front part of the container 5 hits.

Therefore, while the operator pulls out the tray 4, the tray 4 is placed on the stopper 22 and
When the rear end of the tray 4 is pushed downward while being gently pulled backward, the tray 4 and the container 5 (and the articles in the container) slide on the chute 27 due to their own weight. Therefore, it is possible to easily take out the luggage including the tray 4 and the like manually with a light force.

The guide body 30 for pulling out is not limited to the shape extending linearly in a side view, but may be curved in an arc shape in a side view.

By the way, when pulling out the tray 4 from the manual take-out port 7, the rear portion of the tray 4 must first be lifted and placed on the stopper 22. In this case, if the rear end portion of the tray 4 is excessively lifted, The tray 4 and the container 5 are tilted too much forward and the container 5 is detected by the sensor 21.
Is detected, the traveling of the stacker crane 1 is stopped.

Therefore, the front end portion 3 of the guide body 30 for drawing out
By setting the height of 0a such that the upper end surface of the container 5 hits the tray 4 when the tray 4 is tilted forward so as to get over the stopper 22, the tray 4 and the container 5 are separated from each other when the tray 4 is initially taken out. It prevents the stacker crane 1 from traveling due to excessive leaning forward.

When the work is finished after taking out the tray 4,
It is sufficient to push the tray 4 back to the storage shelf 3.

As in the above-mentioned embodiment, when the auxiliary stopper 18 for holding the position of the tray 4 is provided on the shelf plate 15 of the storage shelf 3 having the manual take-out port 7, the tray taken out from the manual take-out port 7 is provided. When the tray 4 is stored again, there is an advantage that the tray 4 can be prevented from being pushed too much toward the traveling path of the stacker crane 1 and the tray 4 can be held at an accurate position.

If the stopper 22 is formed in a roller shape, the tray 4 can be taken in and out more smoothly.

In the above embodiment, the manual take-out port 7 is provided in the storage shelf 3 at the lowermost stage. However, as shown as a second embodiment in FIG. The manual outlet 7 and the chute 27 may be provided.

As can be seen from this embodiment, the manual take-out port 7 may be provided at any height where a person can manually work. Therefore, the manual take-out port 7 and the chute 27 may be provided in all the storage shelves 3 if the worker can work.
