SU122350A1 - Software controller for controlling individual motor units - Google Patents

Description

The software controller is intended for automatic control of individual electric motors of units, for example, a bar, and of the cheese dyeing shops of fur production.

Known software regulators for this purpose, including -. A drive shaft which is forcibly rotated during a cycle time with cams interacting with switches that are included in the circuits of electromagnets.

Such regulators do not provide the possibility of conveniently making, manually, adjustments necessary for the technological process in the operation of individual electric motors of the units serviced by the regulator.

In the described controller, software cams are made in the form of discs with peripheral recesses that interact with spring-loaded contact levers and are frictionally coupled to cantilever axles, which are kinematically connected to the drive shaft with two parallel drives on and off electric motor, rigidly connected with a pin, and a rim rigidly connected to one of the disks and equipped with alarm contacts no interference with the techno OLS; -gichesky process units and on its completion.

FIG. 1 shows a general view from above of the software controller; in fig. 2 is a view of one of the sections of the software controller in two projections; in fig. 3 is a section along AA in FIG. 2

The software controller consists of several sections, each of which is designed to automatically control the individual electric motor of each machine entering the unit.

A motor (not shown in the drawing) and a gearbox 2 are attached to the frame 1, which leads to the insertion of a common worm shaft 4 by means of a gear transmission 3. From the worm shaft 5, the cantilever axes 6 are rotated by means of worm gears 5 number of sections. On each, “axis of the axis, there are two parallel disks, one of which 7 is intended for starting an individual electric motor, and the other disk 8 is for stopping it. Both disks are rigidly interconnected by a pin and are frictionally coupled to the cantilever axis 6 with a nut 9, pressing them against the anvil 10 of axis 6. The disk 8 is rigidly connected to the disk 8, equipped with adjustable contacts 12 for signaling the necessary external interventions in the process and its completion, interacting with the spring-loaded fixed contact 13. Each of the disks 7 and 8 has on the outer circumference of the recess 14, made on time in accordance with the requirements of technology, and interacts with the spring-loaded levers 15 and 16, rotatable around axis 17. On the right end of the levers, teeth are fixed, which fall into the notches of 14 discs, and on the left end of the plate are 18 and 19, making and closing the contacts 20 vi 21 ′ of the magnetic actuator circuit of an individual electric motor. The dial 8 is attached to the dial 8 using the dial 11, on which the machine number and the cycle time are indicated, during which the dial dials make one turn.

The software regulator is equipped with button actuators (not shown in the drawing) for manual control of the equipment and switch 23 from manual control to software control.

The regulator works as follows. Fixing the adjustable contacts 12 on the rim in accordance with the program, transfer the equipment with the help of switch 23 from manual control to program control; 7 and 5 snapshots are mounted on axis 6 to the zero position, corresponding to the zero line on dial 22 with pin 13, and the disks are fixed on the axis with a nut 9. In this position, the tooth on lever 16 abuts against the peripheral disc of fOGTb disc 8 , and the plate 19 closes the contacts 21; the tooth of the lever 15 is retracted in the recess 14 of the disk 7 on the zero mark, and the plate 18 closes the contacts 20. The circuit of the magnetic starter is closed and the corresponding electric motor is driven into rotation.

As the disks 7 and 5 rotate, the tooth of the lever 15 emerges from the recess of the disk 7 and abuts against the peripheral surface of this disk and the plate 18 opens the contacts 20, but the electric motor continues to rotate, and when the tooth of the lever 16 falls into the recess of the disk 8, the plate 19 will open the contacts 21 magnetic starters, and the motor will stop. Upon further rotation of the disks 7 and 5, the tooth of the lever 16 exits from the recess of the disk 8 and rests against its surface, and the cycle of operation;: {reverts.

The change of programs is done by replacing some discs with others during the operation of the unit and can be done independently of the other units.

Subject invention

1. A software controller for controlling individual electric motors of the aggregates, including a drive shaft forcibly rotated during a cycle time, with cams interacting with switches included in the electromagnet circuits, from which in order to provide the possibility of conveniently making manually the adjustments necessary for the operation of individual electric motors of units, for example, in the fur industry serviced by the controller, program cams are made s in the form of discs with peripheral grooves, -interacting with spring-loaded contact levers and frictionally coupled to cantilever axles, kinematically connected to a drive shaft with worm gears. 2. Software controller according to claim 1, characterized in that on the original cantilever axis there are two parallel motor switching and switching disks rigidly connected by a pin, and a rim rigidly connected to one of the disks, equipped with alarm contacts from outside interventions in the process of aggregates and its completion.
