SU132291A1 - Device for remote control of the transport trolley - Google Patents

Description

The known devices for remote control of the transport trolley usually contain photoresistance mounted on the trolley and relays and light sources placed on the path at the places where the cart stops, which are switched on remotely and provide light signals to the photoresistances from the path.

The described device provides not only the stopping of the trolley at the required place, but also the choice of its direction of movement, for which each stopping point is equipped with two light sources, and the trolley with two photoresistances to choose the direction of light pulse delivery with a corresponding light source. 1 shows a diagram of the described device with electrical apparatus and a motor located on a trolley; in fig. 2 --- device diagram with the location of the control panel in any place, for example inside the workshop.

The first scheme allows automatic and manual addressing. With automatic addressing, the transfer of the control command to the trolley is non-contact and the trolley does not have a wired connection to the control panel. Manual addressing is done in the usual way.

As a command sensor, two incandescent luminaires installed at the stop points are used. The primary actuators are photoresistances (for example, of the type "FS-K7), the power dissipation of which allows their direct B circuit to be switched on. The command is given from the control panel, equipped with keys and buttons that switch the lamp on circuit.

No 132291-2 When both lamps come on, the photoresistances of FS i FSA are illuminated, the relays P / SYa and PKHz trigger with their normally open contacts turn on the stopping relay PO. The normally closed contacts of the relay PO, connected in series, break the circuit of contactor B or H, and the cart stops. To send a cart to a given point (forward or backward), one of the lamps is turned off accordingly. When the lamp B is turned off, (Fig. 2), the relay R / SYN switches off and closes contactor B, - the carriage moves forward to the destination point. For carriage, carriage lamp back turns off. The address of the destination (stop) is set by pressing the / SJ button. - The direction of travel to the destination is set by turning on the CL key.

Example. The cart is located in the control panel, the KHi button is pressed. It is necessary to direct the trolley to point p. To do this, release the button KN to turn the key КЛ1 in the direction corresponding to the chosen direction of movement. To stop the cart at point n, press the button KN ,,:

Subject invention

A device for remote control of a transport carriage consisting of photoresistances placed on a carriage and relays placed on the way at the places where light sources stop, which are switched on remotely and which serve to supply light signals to the photoresistance from the way, in order to choose the direction of movement of the carriage Each stopping point is equipped with two light sources and, accordingly, the trolley control circuit contains two photoresistances to make this choice by feeding a light pulse is an appropriate light source.
