Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a shelf having a plurality of compartment storage spaces in the vertical and horizontal directions, and a cargo storage system that can run along the shelf and transfer cargo between the compartment storage spaces. The present invention relates to a warehouse facility comprising a delivery device, an operating section provided below the cargo delivery device, and inspection tables provided at a plurality of locations in the vertical direction.

In the warehouse equipment described above, normal loading and unloading operations are performed under automatic control. By the way, when performing inventory work or when double loading is detected and the cargo delivery device stops and the fork or cargo is being reworked,
Conventionally, a driver sits on the driving section and a worker sits on the inspection platform, and the two communicate by calling out to each other to operate the cargo delivery device.
In this case, only the voice is heard and the two parties cannot confirm each other, so for example, it is possible for the worker to operate the cargo handling device while leaning out from the inspection table, which is very dangerous.

SUMMARY OF THE INVENTION An object of the present invention is to provide a warehouse facility that allows operation in the operating section only when the operator is in a normal position inside the inspection table.

In order to achieve the above object, the warehouse equipment of the present invention is configured such that a pair of left and right matsu switches are arranged at a predetermined interval on each inspection table, and can be operated in the driving section when these matsu switches are turned on. There is.

According to this configuration of the present invention, when the operator is standing out from the inspection table, his/her foot leaves one of the matsu switches and the matsu switch is turned off, thus making it impossible for the operating section to operate. In a normal state when the operator is completely seated within the inspection table, both matsu switches are turned on, and therefore the operating section can be operated. This makes it possible to prevent an extremely dangerous situation in which the worker operates the cargo delivery device while standing on the inspection table.

An embodiment of the present invention will be described below based on the drawings. Reference numeral 1 denotes shelves arranged in parallel, each of which has a plurality of compartment storage spaces 2 in the vertical and horizontal directions, and each compartment storage space 2 can store a load 3. 4 is a passage formed between the shelves 1, and a ceiling rail 5 and a floor rail 6 are provided. Reference numeral 7 denotes a cargo delivery device disposed in the passageway 4, which is guided by the ceiling rail 5 and floor rail 6 and can travel along the shelf 1 within the passageway 4. This cargo delivery device 7 has a pair of front and rear posts 8, and a lifting platform 9 that can be raised and lowered by being guided by these posts 8 is provided with a fork 10 that can be moved in and out in the lateral direction. Reference numeral 11 indicates a traveling drive device, and 12 indicates a lifting drive device. According to this cargo delivery device 7,
By a combination of traveling in the passageway 4, the vertical movement of the lifting platform 9, and the lateral movement of the fork 10, it is possible to move between the desired compartment storage space 2 and the cargo handling area (not shown). Cargo 3 can be delivered.

In the cargo delivery device 7, one post 8
An operating section 13 is provided at the outer lower part of the operating section 13, and inspection tables 14 are provided at multiple locations above and below (four locations in the figure) above the operating section 13. 15 indicates stairs for transfer. Each inspection table 14 has a door 16 that can be opened and closed, and a door switch 17 that detects when the door 16 is closed. Furthermore, on the floor,
A pair of left and right matsu switches 18, 19 are arranged at a predetermined interval. These Matsuto switches 1
The predetermined interval 8, 19 is approximately the length of a stride, and therefore, when the operator steps out from the inspection table 14, one of his feet will lift (separate) from either one of the mat switches 18, 19. Further, the door switch 17 and the matsu switches 18 and 19 are connected to a control section 20, and the control section 20 is configured so that the operation section 13 can be operated only when each switch 17, 18, 19 is all turned on. It is configured. Further, the inspection table 14 is provided with a push button switch 21, and the control unit 20 is configured to operate only when the push button switch 21 is turned on.

When carrying out inventory etc., the driver
Then, the worker gets on the inspection table 14 at the desired level. The worker who has transferred to the inspection table 14 first presses the push button switch 21 to enable the control section 20 corresponding to the inspection table 14.
Then, the worker moves to the inspection table 1 as shown in the solid line in Figure 5.
Starting from 4, we carry out inventory work. Then, the worker and the driver communicate with each other to move the inspection table 14 to the next inventory location.
run. At that time, when the worker is in a position where he or she is leaning out of the inspection table 14 as shown by the solid line in FIG. automatically stopped. Further, when the operator is completely seated in the inspection table 14 as shown by the imaginary line in FIG. 5, since both feet turn on both the mat switches 19, operation in the driving section 13 becomes possible. Note that the door switch 17 is
Since the door 16 is almost certainly closed when the operator transfers to the inspection table 14, it is in the on state. However, if the door 16 is opened for some reason and the cargo delivery device 7 is allowed to travel in this state, there is a risk that the worker may fall due to vibrations during travel. Therefore, when the door 16 is open and the door switch 17 is turned off, the vehicle cannot be operated.
