Description

The invention relates to the transportation and storage of products and materials and can be used to automatically control the movement of closed conveyors of distribution conveyors, swivel hoppers, transfer carts, elevators and other objects. The purpose of the invention is to increase reliability in operation. Fig. 1 is a schematic diagram of the device at seven positions for moving an object; Fig. 2 shows the arrangement of the position sensors along a closed path for moving an object. The device contains a reversing starter with winding; 1 and 1 and 2, interlocking contacts 1.2 and 2.1 of interlocking and closing contacts 1.2 and 2.2 of self-blocking, the address setting device, made in the form of a switch with a moving contact 3 and fixed contacts 3.-3.7 position sensors with opening contacts 4.1 (1-4) - 4.7 (1-4) and closing contacts 4.1 (5.6) 4г7 (5.6) installed at the address of the closed path (the order number of the sensor contact is given in parentheses) Between the second pins of the first clocks 4.1 (1) - 4.7 (1) adjacent position sensors in series with the second contacts 4.1 (2) - 4.7 (2) sensors The positions included the third contacts 4.1 (3) - 4.7 (3) of the sensors related to the positions located at a distance equal to or close to half of the closed path of the object (figure 2}. The first conclusions of the first and fourth contacts 4.1 ( 1) - 4.7 (1) and 4.1 (4). 4.7 (4) sensors are connected to the corresponding fixed contacts 3.1 - 3.7 of the switch, the movable contact 3 of which is connected to the first power supply source. The second pins of the fourth contacts 4.1 (4) 4 .7 (4) are connected via series-connected contacts 1.2 and 2.1 of the starter to the first terminal of the winding 1 of the starter, and through series-connected contacts 2.2 and 1.-1 of the starter are connected to the first end of the winding of the 2 starter . The second outputs of the windings I and 2 of the actuator are connected to the second output of the power source. The connection point of contacts 1.2 and 2.1 of the actuator is connected via contacts 4.1 (5) - 4.7 (5) of the position sensors to the first terminals of contacts 4.1 (3) - 4.7 (3) of their sensors. And the point of connection of contacts 2.2 and 1.1 of the actuator through contacts 4.1 (6) 4 .7 (6) of the position sensors is connected to the second terminals of contacts 4, 1 (3) 4.7 (3) of their sensors. Similarly, a device circuit is constructed for a different number of object stopping positions. In this case, the offset between the second and third. The contacts of the position sensors are selected taking into account the actual distances between the positions of the object stops. The device works as follows. Let the object initially be in a predetermined position with sensor 4.1. In the switch (Fig. 1) contactee 3 and 3.1 are closed, sensor 4.1 is on and its contacts 4.1 (1) - 4.1 (4) are open and contacts 4.1 (5) and 4.1 (6) are closed. Contacts 1.2 and 2.2 of the actuator are open , windings 1 and 2 of the starter are disabled, the object is stationary. For moving an object, for example, to a position with a sensor 4.4, the switch is transferred to the position in which its contacts 3 and 3.4 are closed. When the power source is turned on, a circuit is formed: the first output of the power supply - contacts 3-3.44 .4 (1) - 4.4 (2) - 4.U5) -2.I - winding 1 - the second output of the power supply. The winding 1 of the starter is turned on and the object starts moving clockwise (Fig. 2). At the same time, an additional circuit is formed through pin 4.4 (4) and the activated contact 1.2 of the starter. Winding 2 actuator cannot be switched on, since its circuit is open by contacts 4.1 (2) and 4.1 (3). With the departure of the object from the initial position, the sensor 4. 1 is turned off and the switch-; All of its pins are switched off, but the coil of the starter 1 is not disconnected, as it is powered through an additional circuit. The object continues moving. When an object arrives at a given position, sensor 4.4 is turned on, contacts 4.4 (1 I and 4.4 (4) are open.

winding 1 is turned off, the object is stopped.

To move an object from its original position with sensor 4.1, for example, to a position with sensor 4.6 in the switch, its contacts 3 and 3.6 are closed. A circuit is formed: the first output of the power source - contacts 3-3.6-4.6 (1) -4.2 (3) A .5 (2 M. 1 (6S, 1 - winding 2 - SECOND output of the power source. Turns on winding 2 of the actuator and the object begins to move counterclockwise (figure 2). At the same time winding 186560 4

ka 2 receives power through an additional circuit through contacts 4.6 (4J and 2.2.

When an object arrives at position 5 with sensor 4.6, its contacts 4.6 (I) and 4.6 (4) open, winding 2 turns off, the object stops coming to a predetermined position, as in the previous case, the shortest way.

0 The device works in a similar way for other initial positions of the object, ensuring its movement to any given position by the shortest path.
