Description

[Detailed Description of the Invention] [Detailed Description of the Invention] The present invention relates to an improvement of a car number selection device in a multi-story parking lot.

Figures 1 to 3 show an example of a car number selection device in a conventional vertical circulation multi-story parking lot. In these figures, 1 is a cage, 2 is a lower sprocket, 3 is an encoder, and 4 is a CPU. An operation panel consisting of a circuit 4a, an FL unit 4b, an I.OI/F circuit 4c, etc., 5 is a landing cage detection limit switch, 6 is a cage detection limit switch, and the number of the landing cage is determined by rotating the lower sprocket 2. This is done by inputting information to the operation panel 4 via the encoder 3 as shown in FIG. This encoder 3 is an indispensable part for the landing number determination function in current multi-story parking lots, but the encoder 3 is a highly accurate electrical part, and there are problems with quality control in manufacturing and installation of related parts. be. That is, the encoder 3 is manufactured with high precision by an electrical manufacturer, but at the time of on-site installation, it is attached to a mounting base manufactured by a machine manufacturer, so it is necessary to control the manufacturing accuracy of the mounting base at the manufacturing stage.
The above-mentioned conventional device has a drawback in that there are problems in centering precision control at the time of installation, and it is difficult to maintain high precision as a whole.

The present invention was proposed with the aim of solving the above-mentioned drawbacks of the conventional device and providing a cage number selection device that can reliably select an implantation cage number without using the problematic encoder. A protrusion that activates a limit switch for detecting a specific cage at the car park is installed on an attachment attached to the specific cage hanging shaft, and the detection signal is sent to the control panel.
In addition to inputting the I.OI/F circuit into the I.OI/F circuit, the left rotation command, right rotation command, and landing cage detection limit switch command for each cage are input to the I.OI/F circuit on the operation panel.
This invention relates to a car number selection device in a multi-story parking lot, characterized in that it is configured to input data to an OI/F circuit.

Hereinafter, according to the embodiments shown in FIGS. 4 to 6,
The present invention will be explained in detail. In those figures,
1 is a cage, 2 is a lower sprocket, 4 is an operation panel, 5 is a limit switch for detecting a landing cage, 6
is a limit switch for detecting a specific cage, and the configuration, operation, and mutual relationship structure of these members is such that a protrusion that operates the limit switch 6 for detecting a specific cage is installed on the chain attachment 7 of the specific cage hanging shaft, and the signal is is configured to be input to the I.OI/F circuit 4c of the operation panel 4, and the left rotation command, right rotation command, and landing cage detection limit switch 5 command are input to the I.OI/F circuit 4c of the operation panel 4. 4c, and is configured to determine the landing cage number using each circuit configuration. (Equivalent parts are given the same reference numerals.) For example, in the case of a cage in a vertical circulation multi-level parking lot that accommodates 16 cars, it is assumed that it is located on the upper left side of the parking lot.
The procedure for calling cage No. 8 is as shown in the following order (i) to (v).

(i) #8 of the built-in keyboard of the operation carrier 4
The call cage number is entered on the operation panel 4 by pressing the button.

(ii) Inside the operation panel, a rotation direction (clockwise rotation) command is output based on the landing cage number (#1) at that time. Further, the target cage number is displayed on the FL unit 4b.

(iii) When the landing cage detection limit switch 5 is activated on the cage hanging shaft, the landing number 1 increases by +1.
I'm going to be done.

(iv) When the landing number in the FL unit 4b and the target cage number become the same, a deceleration command is output.

(v) When the cage is in deceleration operation and the landing cage detection limit switch 5 is activated, a stop command is output and the cage is stopped.

One embodiment of the device of the present invention is configured as described above, and includes a limit switch 6 for detecting a specific cage.
Enter only the No. 1 cage specific position into the operation panel 4, and use this as the reference address. In addition, by inputting a command to the limit switch 5 for detecting the landing cage, the operation panel 4 is activated.
When the CPU circuit 4a is set, a program is constructed that counts UP+1 when rotating to the left and counts DOUN-1 when rotating clockwise.

Since the device of the present invention has the above-mentioned configuration and function, the present invention does not use an encoder, which is an essential part of the conventional device, and therefore requires the installation, mounting hardware, and lower part of the encoder. This eliminates the need for a mechanism, cable, etc. for transmitting the rotation of the sprocket 2 to the encoder, and has the practical effect of improving the reliability of the entire system.
