Description

[Detailed Description of the Invention] The present invention relates to a control device for a circulating storage facility such as a mechanical multi-level parking lot.

Generally, in a multi-story parking lot, the current situation is that vehicles for accommodating vehicles (usually referred to as cages) are called to the entrance/exit section of each vehicle on a first-come, first-served basis.

By the way, when a department store is closed or a meeting is dismissed, the above-mentioned first-come, first-served priority calling system is inefficient due to the long waiting time and operation time, and the power consumption of the drive device is also large.

Therefore, in combination with a computer, after registering the carrier number that you want to call, you can select the one closest to the entrance and exit from among them and issue commands in order. Therefore, it is extremely uneconomical and impractical to use it in the above-mentioned multi-story parking lot.

Additionally, since multi-story parking lots are equipped with display devices and operation status indicators, there is a method in which the operator uses these to select the carrier closest to the entrance and call it. It was not something that would be done.

The present invention was developed in view of the above-mentioned circumstances.In a storage facility in which a large number of carriers storing articles are moved in a circular manner, each registration confirmation indicator light is provided in a number corresponding to the number of carriers and when a call operation is performed. A carrier call registration switch that lights up, a registration memory relay that is energized and self-maintained when the registration switch is called, and a start relay that drives the carrier moving device when the start switch is operated. A selector switch that switches a switch corresponding to the carrier when the carrier arrives at the calling position, and an arrival confirmation relay that is energized when any switch in the selector switch is switched. and is characterized in that the carrier moving device can be stopped when the arrival confirmation relay is energized.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic diagram of a multistory parking lot as an example of a circulating storage facility. Vehicles 6 can be accommodated in carriers 5 installed at appropriate intervals, and chain 4 is rotated by driving sprocket 3 (or 2) with drive motor M.
It is configured such that a vehicle 6 can be brought in and taken out at an entrance/exit 7.

Further, as shown in FIG. 2, on the operation panel 8 for calling each carrier 5 to the entrance/exit 7, the same number of registration pushbutton switches 9 as the number of carriers 5 are consecutively arranged (1 to 10 in the figure). Accordingly, each carrier 5 is also successively arranged in correspondence with the number of the push button switch 9. Furthermore, a lamp (not shown) is built into the pushbutton switch 9, and when the pushbutton switch 9 corresponding to the carrier 5 to be called is pressed, the lamp lights up to confirm the registration. The drive motor M of the sprocket 3 can be driven to call the registered carrier 5 by pressing a start button switch 10 provided at an appropriate location.

Furthermore, in the present invention, when there are a plurality of registered pushbutton switches 9, a control circuit as shown in FIG. 3 is provided so that they can be called from the carrier 5 located closest to the entrance/exit 7.

In FIG. 3, Po-N is a 24V DC control circuit power supply, AX ₁ to AX ₁₀ are memory relays for carrier call registration, and 9 ₁ to 9 ₁₀ are push button switches. For convenience of explanation, the subscripts PL ₁ to PL ₁₀ are registration confirmation indicator lights incorporated in the pushbutton switches 9 ₁ to 9 ₁₀ , and C ₁ to _{C 10} are switches in the selector switch 11 and the carrier 5. The one _that operates in synchronization with the movement _of Yes confirmation relay,
10 is a start button switch in Fig. 2;
START is a relay that remembers the start after registration is completed PLo ₁ is the start button switch 1
0, ON confirmation indicator light, ar is the contact of the automatic mode switching confirmation relay (the relay is not shown), RY is the arrival confirmation relay that operates every time the registered carrier 5 arrives, and D is the backflow prevention diode. The contacts of each relay are indicated by the corresponding relay's lowercase letter.

Moreover, FIG. 4 shows the power circuit of the drive motor M and its operation circuit, R and S are the operation circuit power supply, RZ is the electromagnetic contactor coil of the motor M, rz is the contact point of the electromagnetic contactor coil RZ, start, rx is in Figure 3
These are START and RX contacts.

Next, the operation will be explained.

If you want to call multiple carriers 5, first,
Push all the pushbutton switches 9 corresponding to the plurality of carriers 5 that you wish to call. Now, let's say No. 2, No.
3. Push button switch 9 ₂ as No. 10 carrier 5,
Let's press 9 ₃ , 9 ₁₀ . Then, registration memory relays AX ₂ , AX ₃ , and AX ₁₀ are activated and self-hold.
At the same time, the registration confirmation indicator lights PL ₂ , PL ₃ , PL ₁₀ in the pushbutton switches 9 ₂ , 9 ₃ , 9 ₁₀ light up to confirm the registration. Next, when the start button switch 10 is pressed, the start relay START is activated and self-holds. At the same time, the confirmation indicator light PLo ₁ in the start button switch 10 lights up. Subsequently, as shown in FIG. 4, the electromagnetic contactor RZ is operated by the contact start to drive the motor M. When the motor M is driven, the No. 2 carriage 5 moves toward the entrance/exit 7, and when it reaches the entrance/exit 7, the switch _C2 in the selector switch 11 is switched and the normally closed contact is opened. When switch C ₂ switches, power Po - relay RY - contact ax ₂ - switch C ₂
-The loop of power supply N becomes a closed circuit, and relay RY is activated. When the relay RY is activated, the relays AX ₂ , RX, and START, which had been self-holding until now, are de-energized and the respective contacts ax ₂ , rx, and start are opened.
When each contact ax ₂ , rx, and start are opened in this way,
The electromagnetic contactor RZ in FIG. 4 is opened and the motor M stops. After the No. 2 carrier 5 leaves the warehouse (or may enter the warehouse), the start button switch 10 is operated again.

When you operate the start button switch 10 again,
The above operation is repeated and motor M is driven again, and No. 3
The carrier 5 arrives at the doorway 7 and leaves the warehouse.

Next, when the start button switch 10 is pressed again, the motor M is driven, and even if the No. 4 carriage 5 comes and the switch C ₄ is turned ON, the No. 4 registration memory relay AX ₄ does not operate, so the relay RY is activated. No. 4 carrier 5 passed without stopping, and thereafter, carriers 5 from No. 4 to No. 9 also passed in sequence, and switch C ₁₀ for No. 10 carrier 5 was turned ON and relay RY was activated again. Then, the motor M stops as before.

As described above, when a plurality of calls are registered, calls can be made sequentially from the first carrier 5 that arrives at the entrance/exit 7 regardless of the registration order.

In the above embodiment, the direction of circulation of the carrier was fixed, but since it is possible to automatically select the shortest direction with respect to the entrance/exit using a known method, the explanation thereof will be omitted. Further, since the selector switch is a well-known fact, explanation of its functional structure and the like has been intentionally omitted.

As mentioned above, according to the present invention, (i) During continuous unloading (or restocking), the carrier closest to the entrance can be automatically selected and called;
Eliminates loss of time for calling for delivery.

(ii) Since the carriers to be called up can be operated and registered in an appropriate order, the operator does not need to organize the registration order and does not need to make any judgments on the part of the operator.

(iii) Cost is low as no expensive equipment such as a computer is required.

(iv) Can be easily integrated into currently operating equipment.

(v) The registered carrier number can be displayed.

It can produce excellent effects such as
