SU1509316A1 - Automatic device for selecting direction of movement of an object - Google Patents

Abstract

The invention relates to industrial transport and can be used to control the movement of various objects with fixed stopping positions, in particular trolleys, hoists, and storage mechanisms. The purpose of the invention is to increase reliability. The device contains forward and backward starters, an address memory relay, an interpositional stop relay, an inhibition relay, an object position sensor installed at the address positions, an address setting and cancel button, and diodes. The power circuits of the windings of the starter actuators forwards, backwards include the closing contacts of the sensors of the object position, the memory relay of the address of adjacent addressing positions, and through diodes the subsequent and previous addressing positions. The address is set by the corresponding button. The memory relay of the address through the closing contact of the corresponding sensor of the position of the object energizes the winding of the starter forward or backward. Having reached the specified addressing position, the object interacts with the corresponding position sensor, which de-energizes the actuator, and the object stops at the specified position. 1 il.

19.2 and opening switches 19.3, 19.4, a backward movement actuator with a winding 20.1, closing contact 20.2 and opening switches 20.3, 20.4.

In the supply circuit of the windings 12.1 ... 15. the address memory relay switches on the opening contact 17 of the address cancel button, the corresponding closing contacts 12.2–15.2, which are in parallel via the opening contact 16.2 of the inhibit relay and the series-connected disconnecting contacts

8.2- 11.2 of the previous address setting buttons The closing contacts 8.1-11.1 of the corresponding address setting buttons are connected.

The closing contacts 12.3 - 15.3 of the address memory relay are connected in parallel to the power supply circuit of the winding 16.1 of the inhibit relay.

In the power supply circuit of the winding 18.1 of the interpositional stop relay, the disconnecting contacts 4.2–7.2 of the object position sensors and 19.4 and 20.4 starters are connected in series. Parallel to the last two, the closing contact 18.2 of the interpositional positioning relay is connected.

In the power supply circuit of the windings 19.1 and 20.1 of the forward and backward starters, through jogging contacts 20.3 and 19.3, respectively, jio are connected, therefore closing contacts

4.3–6.3 and 5.4, 6.4, 7.3 position sensors installed at the subsequent first and previous last positions of the addressing, respectively, closing contacts 13.4–15.4 and 12.4, 13.5, 14.5 of the address memory relay,

and through diodes 1.2 and 3.1, 3.2 - subsequent and previous. Parallel to the positioning contacts 4.3 and 7.3, the positioning contacts 19.2 and 20.2 of the forward and reverse starters, respectively, are included. B food chain. Winding 20.1 start

The backward motion catcher is connected to the closing contact 18.3 of the interpositional relay.

The device works as follows.

Suppose the object is in the third address position. Opened the contacts 6.1, 6.2 of the position sensor of the object are open in the

the windings 14.1 of the address memory relay and the windings 18.1 of the interposition stopping relay, and the closing contacts 6.3 and 6.4 of the sensor are closed in the windings 19.1 and 20.1 of the starters.

Setting a new address, for example a second one, is degraded by pressing the corresponding button, the closing contact 9.1 which supplies power to the winding 13.1. The address memory relay is activated, self-blocking by the closing contact 13.2 and the closing contact 13.5 through the closing contact 6.4 of the position sensor of the object, supplies power to the winding 20.1 of the reverse motion back switch. The starter is triggered, self-blocking by closing contact 20.2 to automatically end the movement to the specified address. The object moves in the specified direction to the second address position. Included the closing contact 13.3 of the prohibition relay; the opening contact 16.2 excludes the assignment of another address during the movement of the object.

Having reached the specified addressing position, the object interacts with a position sensor, the opening contact 5.1 of which de-energizes the winding 13.1 of the address memory relay, which disables the forward drive starter. The object stops at a predetermined position.

To cancel the address, a button is pressed, the opening contact 17 of which de-energizes the winding of the relay 12. 1.. 1 address memory.

If, at the moment of the address cancellation, the object stopped between the addressing positions, along the chain: 4.2–7.2, 19.4, and 20.4, the in-position stopping relay is activated, which by the closing contact 18.3 through the contact .19.3 the forward actuator supplies power to the winding 20.1. starter backward. The object moves to the first addressing position, at which the position sensor by opening contact 4.2 - 7.2 de-energizes the winding 18.1 at the interpositional stop turn, the closing contact 18.3 of which turns off the starting starter.

Similarly, the object is removed from the intermediate position with the disappearance of the voltage and its subsequent restoration.
