(54) DEVICE FOR MANAGING THE WORKING BODIES OF THE ROUND-BANDING MACHINE

one

The invention relates to the field of knitting machine-building, in particular, to a device for controlling the working bodies of a circular beater, for example, round-broom.

A similar device is known, which contains a software drum connected to the mechanism of rotation of the counting circuit and an electric meter of the number of pushes.

The purpose of the invention is to increase the reliability of the device in operation.

This is achieved by the fact that the electric meter contains a switch system, and the device is equipped with an additional program carrier, for example, a drum drum mounted on the program drum, and a block of selector levers in contact with the additional program carrier and the switch system.

FIG. 1 schematically shows the proposed device; in fig. 2 - additional program carrier and block of selector levers, view in plan; in fig. 3 is his electrical circuit.

The device for controlling the working bodies of the circular machine has a program drum 1 with dies 2, from

which receive control levers working bodies (not shown in the drawings).

On the drum 1 is fixed ratchet wheel 3, interacting with the pawl 4, mounted on the axis 5 of the pushing lever 6. The lever 6 is fixed on the axis 7 and carries the roller 8, seated on the axis 9. The roller 8 contacts the fist 10. The roller 8 is pressed to the fist 10 a spring 11 connecting the arm b to the bed 12.

On the program drum 1, an additional program carrier 13 is fixed, made in the form of a spiky drum, having rows of holes 14, and pegs 15, recruited according to the program. The rows of holes 14 are oriented parallel with the axis of the programmer carrier 13 or with the axis of drum 1 so that one row corresponds to one pushing, as a result, the number of rows

holes 14 and the number of teeth of the ratchet wheel 3.

Block 16 selector levers installed with the possibility of contact with an additional program carrier 3 and the system 17 switches. One of the levers 18 is in contact with only one pin, the position of which corresponds to the beginning in the range of the product (for example, stocking). This extreme lever 18 interacts with a switch 19, manually controlled and connected to the circuit of an electric meter 20, which is controlled by a switch 21 and a switch 22 and consists of a generator 23, a counter of 24 higher rows and a counter of 25 lower rows, to the storage elements of which switches 17 are connected via the terminal board 26. A switch 19 connected to the amplifier 27 of the electric meter 20 is also connected through this board.

The amplifier 27 is connected to the electromagnet 28. The counter 20 is controlled by a switch 29 connected to the generator 23 for driving the counters 24 and 25. The rotating mechanism of the counting circuit contains a double-arm lever 30 mounted rotatably on an axis 31. One end of the lever 30 interacts with the pawl pin 32 4, and the other with dies 33 of the counting circuit 34. On the axis 31, a double-arm lever 35 is also mounted in contact with the dies 36 of the counting circuit 34. The dies 36 are located adjacent to the dies 33. The other arm of the lever 35 contacts the switch 29.

The counting circuit 34 is mounted on two wheels 37 and 38. The wheel 37 is equipped with a ratchet 39, with which the dog 40 interacts, freely seated on the axis 41 of the pushing lever 42. The latter is seated on the axis 43 and one of its shoulders carries the semi-axis 44 with the roller 45 resting on the fist 46.

The cam 46 is kinematically associated with the needle cylinder in the mask housing (not shown in the drawing). The lever 42 is connected with the bed 12 by means of a compression spring 47. At the lower arm of the lever 42, a protrusion 48 is made in contact with the switch 21.

The dog 40 is controlled by an electromagnet 28 via a core 49 connected to the spring 50.

The device works as follows.

The counter circuit 34 is pushed in the direction of the arrow A. The plate 33 lifts the lever 30, which rotates on the axis 31. As a result, the pin 32, and hence the doggie 4, is lowered. The dog 4 comes into contact with the teeth of the wheel 3, and the program drum 1 together with the additional program carrier 13 rotates in the direction of arrow B by one row of spikes 15.

Upon further movement of the counting circuit 34 in the direction of arrow A, the lever 30 comes off the jacket 33 and by means of the pin 32 lifts the dog 4 and thus removes it from work.

At the approach of the corresponding row of punches 15, the arms 16 corresponding to the set of hammers, which, in turn, turn up the switches of the system 17, and

information about the number of pushings of the counting circuit 34 is entered into the corresponding elements of the memory of the counter 24 and 25 high and low rows. After recording this information, the plate 36 lifts the lever 35, causing the switch 29 to close, and with it the contour of the electric meter 20. But the electromagnet 28 turns on, its measles 49, breaking the force of the spring 50, raises the pawl 40, and the counter circuit 34 turns off from work. The fist 46, continuing to rotate, swings the lever 42, the protrusion 48 of which rhythmically closes the switch 21, which thus considers the revolutions of the needle cylinder of the machine.

The generator 23 of the drive counters 24 and 25 causes the promotion of information about the number of revolutions on the elements of the storage device. And as soon as the number of revolutions read by the switch 21 corresponds to the number of pegs 15, the output of the amplifier 27 is a signal that turns off the electromagnet 28. The dog 40 enters the ratchet tooth 39 and the counter circuit 34 rotates. Thus, smooth cloaks (zero) of the counting circuit are replaced.

Then the lever 35 comes off the plate 36 and through the switch 29 turns off the circuit of the electric meter 20. The next plate lifts the lever 30, which turns the additional program carrier 13.

In the event of a defect in the product, the needle cylinder of the machine, and therefore the cam 46, is stopped. After the elimination of the defect, manually switch off the switch 19, and the circuit of the counter 20 is interrupted. As a consequence, no current flows through the electromagnet 28, and the counting circuit 34, the drum 1 and the program carrier 13 rotate until they enter the "Start.

The machine is brought to the starting position and is ready for reading a new product.

The proposed device is automatically set to its original position, which increases its reliability in operation.
