Description

one

The invention relates to devices for controlling the geometrical shape of cylindrical products, in particular, yarn cobs at various transitions of spinning production.

Devices are known for controlling the geometrical shape of cylindrical articles, comprising a hopper, a trap, a porter, a measuring device, photo-detectors, a tiratryl relay and an execution mechanism.

The proposed device makes it possible to control the minimum and maximum diameter of the coil winding, the required geometric shape of the cob EO over its entire length.

It is achieved that the measuring device is made in the form of lamellae of various lengths and a figured plate loosely fixed on the axis perpendicular to the direction of movement of the ears, and the executive mechanism consists of three disks with rollers movably mounted between them, a rotating ribbed disk and a rocker arm. In this case, the ribbed disk is loosely mounted on one end of the rocker, the other end of which is connected to the thyratron relay electromagnet.

FIG. 1 shows the proposed device, a general view; in fig. 2 - geometric shape of the cob of yarn; “And FIG. 3 - the device, side view; in fig. 4 - section along

on f: ig. eight; in fig. 10 is a circuit diagram of the proposed device.

The device consists of a bunker}, a belt conveyor 2, a measuring device 3, a photo sensor 4, a thyratron 5 a

actuator.

The tape axle sprinter .2 consists of an elastic band 6, a spindle 7 and two guide drums 8. The tape carries 9, which are located all over the perlmeter in two rows. Pr, and the movement of the conveyor belt and the cob of the yarn from the bunker are grasped by plankalsh 9 and fed to the measuring device; bloc 3. The last compost is 3 "10 buslets of 10 different lengths, freely suspended on the axes //, the ends of which (Copy the geometric shape of mined sizes cob, and figured solid plate 12, the lower end of which is cut but the contour of a geometric shape

maximum size of cob. Plate 12 is freely suspended on axis 13.

The actuating mechanism consists of i; 3 three discs 14 rigidly seated on the axis 15 of the drive gear 16, rocker arm 17 and the ribbed IS disc.

Between the disks in special slots are fatigued. Rollers 19. It is blunt, the wheel 16 receives a rotation 1Pr: and the movement of the tape 6 by means of the strips 9, carried out a reduction of the movement along the ChT | Cove and the disks 14. C; redn part of the rocker arms 17 Freely mounted on the shaft of the electroplator 20, transmitting the rotation of the disk 18, and the last - on the left end of the rocker arm 17, the right one (the end of which is connected to the electromotor; m 2: 1 THipanpoHfloro relay.

The device works as follows.

The movement is pochato, it touches the lam- ple of the elbk 10 to its lateral surface and deflects them by the amount of passage of the light beam from the llamas | PO) H, the illumination to the photo sensor.

If all the bars are deflected, then the tails are minuscule by the minimum dimensions, but if one or several of the tracks are deflected, then its dimensions are less than M1 minimum.

The coarse pattern is divided, maximized | maximally from each other, and the cob consists in not deviating the plate 12 from its vertical position. Each patch is monitored under two measuring strains; This is due to the fact that the left and right kotits of the consum have a different geometric shape (fit. 2), and from) the middle and the idle and give the conveyor randomly, without .preliminary 0 | rkent1TS1I.

At the time of the ipod position, the disk 18, the roller 19 is under the contact 23, which turns on the electromagnet 21. The roller may be in the left or right side of the gap between the disks 14. But the first position of the roller is left.

IF a good cob goes through (i.e., the lamellae are rejected, and the plate is fixed), the photosensors 4 through the thyratrons 5 (Fig. 10) turn on the electromagnet 24, and the roller 19 is shifted to the right position. At this moment, the contact 23 does not touch the rotor 19, the electromagnet 21 is turned off, the disk 18 is in the upper position. And the ear, without touching the disk, falls into the box 22.

The device circuit consists of a common power supply unit, two photo sensors, two photo sensor illumination bulbs, two electronic memory tiratrons, polarity lamps, mechanical memory recording tiratrons from the elec: ktro.mag.nitom 24, electromagnet erasing software 25 and a common control device to monitor the operation of photosensors. After a brief breakdown of the co-operation of the co-contacts with the darkened photo-data: ch.i.k.Ti.trona of the electronic memory L and L, they remain the same per negative voltage across the control grid. The t.ratron of the recording of the L on the control grid of the driving grid through the lamp. Changing the polarity.

and on the screen grid is in operation. When the photo sensor is photographed, the corresponding cob geometry is minimal, the size of the tirar. It / 7i is triggered and the open

L over the control grid. At the time of the next actuation of the com.andocoigact of the thyratron L opens, the recording electromagnet 24 will move the R. 191 to the interval, which will correspond to high-quality readings.

When another photo sensor is lit, corresponding to the pasiMeipy cob to the maximum, the L thyratron L is triggered. And depth: Ko closes the recording on the screen grid

thyratron. Then, milestone | H "74 regardless of the arrival of the control panel on the control grid at the time of the next switching of the command contacts will be closed, the electric magnet 24 will not move the roller 19 to the right position, and

: Contact 23 will turn on the electromagnet 21. At the same time, the left shoulder of the coro (the THOUGHT is lowered, and the disk 18 will direct the arm to shchi 26.

The subject is invented and

A device for controlling the geometric shape of ciliardic. Products, containing a bunker, a conveyor belt, a measuring device, a photo sensing device, tiratr.on relays and

an actuator, characterized in that, in order to ensure the possibility of measuring the shape of the cobs of the production line and improving the quality of their control, the measuring device was made IB in the form of diamonds of different lengths and a figured plate freely mounted on the backplate Dic; strno direction of movement of the wadding, and the executive, mechanical-ism consists of three disks with movably mounted between the N of the R. OLIKS, a rotating re-riated hard disc and rocker arm, while the ribbed disc is freely mounted on the end of the rocker arm, other the end of which is connected with the electromagnet of the thyratron relay.
