The vehicle body (19) is sequentially driven to the side, and when the replenishment of goods is completed, the vehicle body (19) is driven to the origin location. However, in order to prevent the vehicle body (19) from running out of control due to detection errors in various sensors, etc., while checking whether or not deceleration is necessary based on information from the forward deceleration sensor (36b) and the reverse deceleration sensor (36c), The system also performs an emergency stop while decelerating the vehicle and checking whether or not an emergency stop is necessary based on the information ζ from the emergency stop sensor (36a).

That is, as shown in the flowchart of FIG. 19, first, it is checked whether the vehicle is running or not, and if it is not, it is checked whether the article replenishment work has been completed and whether the vehicle body (19) is moved for article replenishment. The necessity of running is checked while determining whether or not to continue stopping the vehicle.

If it is necessary to travel, when replenishing supplies, decide how far to travel and advance to the next target position,
Further, when the replenishment of goods is completed, processing is executed to determine the direction and amount of travel, such as deciding to move backward, and based on the results, the vehicle body (19) is caused to travel.

When the vehicle is traveling in the above-mentioned directions J and Z7, or after the vehicle has started traveling, it is checked whether or not the vehicle is traveling to the origin.

When traveling to the origin, the origin detection sensor (36d
) is checked to see if it is at the origin position, and if it is at the origin position, the traveling brake (35) is activated to stop the vehicle body (19).

If the vehicle is not traveling to the origin, it is checked whether the vehicle has traveled to the target position based on the information of the encoder (34), and if the vehicle is at the target position, the travel brake (35) is actuated to move the vehicle body (19). ) to stop.

If it is neither the origin position nor the target position, it is checked whether it is at the deceleration position based on the information of the forward deceleration sensor (36b) and the backward deceleration sensor (36c),
If it is at the deceleration position, it executes deceleration processing, and also checks whether or not it is at the emergency stop position based on the information of the emergency stop sensor (36d), and if it is at the emergency stop position, the vehicle is stopped for traveling. Activate the brake (35) and move the vehicle body (1)
9) Execute the process to stop.

In the surplus space detection process, when the vehicle body (19) stops at the target position, it is determined which of the four stages of front suspension the surplus space is based on the detection information of the surplus space detection sensor (39).

As shown in FIG. 20, the article replenishment stop processing is carried out when
19) has stopped at the target position to be replenished, and only if it has stopped, check the size of the article (Xa) to be replenished into the article storage zone (N) and the article storage zone (N). Compare the free space of the goods (
Check whether there is space to replenish Xa),
If there is no space, a process for instructing to stop replenishing items is executed.

In the extruder part movement process, the extruder part movement motor (30) is rotated by a fixed amount only when there is no instruction to stop replenishment of articles.

Note that when the article replenishment is stopped, the worker removes the excess article (Xa) and continues the article replenishment work.

[Another example]

In carrying out the present invention, the specific configuration of the container conveying means (G),
The specific configuration of the shelf (5), the specific configuration of the instruction means (D), etc. are as follows.
Various changes can be made according to the purpose of use.

In the above-described embodiment, the article replenishment means (L) is configured by a worker supplying replenishment articles to the article conveyance line (1) based on instructions from the notification means (F), and this is carried out semi-automatically. However, it is also possible to provide the article conveyance line (1) with a conveyance line that automatically supplies replenishment articles so that the process can be carried out fully automatically. It goes without saying that even in the case of fully automatic operation, various configuration changes can be made.

To constitute the extra space detection means, each article storage zone (N) may be equipped with a separate sensor (39), and in this case, when replenishing articles,
It is preferable to stop the replenishment of articles to the unnecessary zone (Z) by removing the article replenishment data for the unnecessary zone (Z) in advance.

Incidentally, in the above-described embodiment, the spare space is detected in multiple stages in order to cope with cases where the sizes of the boxed articles (Xa) stored in each article storage zone (N) are different. In cases such as when the sizes of the articles (Xa) are the same, only whether or not there is a predetermined amount of extra space may be detected.
