Description

The invention relates to electrical means of automatic control used in industrial units and mechanisms, and can be used to automatically select the direction of movement of the transfer carriage with a concrete product moving from the forming conveyor to two heat treatment lines.

The aim of the invention is to simplify the design of the device

Figure 1 shows the functional diagram of the device; on - the basic scheme.

The transfer carriage 1 (FIG) moves from the initial position — the formation line — to the first and second heat treatment lines. On the path of the trolley is installed:.) Travel switches 2, 3 and 4.

The device diagram (FIG. 2) contains a start button 5 and a stop button 6 moving to the right, which is connected in series with the winding of the time relay 7 and connected via a slip contact 7.1 and the contacts Sol, 8.2 to the winding of the pos-point relay 8.

Disconnection of the cat ears of the time relay 7 occurs by the contact of the actuator 10 when the body / hki movement moves back to the formation line ,, Slipping contact 7.1 time relay 7 is set

 relay 8. Thus, an automatic selection of the direction of the engine of the transfer car from the forking line to the first 51

Terminals 3.1 and 4.1 of the circuit breakers, for the exception of a multiple trigger, 3 and 4 are connected in series with contacts 8.3 and 8 „4 of the position relay 8, which are connected to the winding of the actuator 9 via a speed switch

It is connected to one of the poles of the power supply. The reset key 11 connects the disconnecting contact 2.1 of the traveling disconnector 2 through the opening contact 9.2 of the actuator 9 to the coil of the actuator 10 Stopping the transfer trolley when moving Left or Right with button 5, through which the control circuits are switched.

 The device works as follows.

In the initial position, the transfer carriage 1 is on the line forming the product. When the button 5 is turned on, time relay 7 is turned on; which by its sliding contact 7.1, through contact 8.2, gives an impulse to switch position relay B. Contacts 8.1 and 8.3 are closed, and contacts 8.2 and open; pins 3.1 and 4.1 are closed, through
