Abstract

The invention relates to the production of chemical fibers. The purpose of the invention is to improve the performance properties by improving the reliability and simplifying the design. This goal is achieved by the fact that the probe-harness guide further comprises a hollow element and is installed with the possibility of deflection by means of a harness during its movement to 80-120, while the probe is connected to the body by means of elastic pipes, through which the compressed air enters the control mechanism. 6 Il.

Description

one

The invention relates to the manufacture of chemical filaments and fibers, in particular, is intended for use on wet-forming machines in highly aggressive and explosive environments.

The purpose of the invention is to improve the performance properties of the device by simplifying its design and increasing reliability.

Fig. 1 shows a device for controlling the movement of a chemical filament or a bundle of filaments on a molding machine (for a tow or filament arranged in a horizontal plane), the initial position; 2 is the same, top view; FIG. 3 shows a device for the case when the rope or thread is arranged in a horizontal plane, the working position; 4 is a device for the case.

when the rope or thread is located in a vertical plane, the initial position is, in FIG. 5, the same working position; 6 shows a variant of the device design with the return to the original position due to the elasticity of the elastic tubes.

The control device consists of a fixed housing 1, which is mounted on a molding machine, a tongue-harness 2 for gripping a harness 3. The probe is equipped with a counterweight 4, which can be rotated around an axis 5. In addition, the probe harness 2 is provided with a hollow - ment 6, which is connected to the housing 1 by two elastic tubes 7. In Fig.2, the arrows show the path of compressed air that passes through the housing 1, the elastic tubes 7 and the hollow element 6. The exit from the housing 1,

compressed air is supplied to an actuator, for example, a pneumatic electric converter or to a sound or light alarm device.

The control device operates as follows.

The housing 1 of the device is fixed to any element of the machine in the region of the passage of the controlled harness 3. Compressed air (shown by arrows) is supplied to the housing 1 and then through the elastic tube 7 through the hollow element 6, the second elastic tube an executive (for example, to a pneumatic cylinder) or a signaling mechanism (for example, to a sound or light) mechanism. In the absence of a harness, compressed air is blocked by a tap or valve and is not supplied to the device, and the actuator or alarm device does not work. Due to the counterweight 4 or the elasticity of the elastic tubes 7, the probe-strap- ruler 2 is in the starting position. In order to fix the moment of breakage of harness 3, the latter is loaded into probe-harness 2. As a result, elastic tubes 7 are deformed (fig. 3, 5 and 6), and the up-harness turns around axis 5 and continues to be held in position harness. In this position, the cable harness of the device is supplied with compressed air, which is not supplied to the actuating or signaling mechanisms, since the elastic tubes work as hose clamps.

With a breakage of the harness. 3 probe-harness. due to the elastic forces of the elastic tubes and the counterweight, turning around axis 5 returns to the initial position (Figures 1, 2 and 4). The elastic tubes are expanded and the compressed air supplied to the control device through the first elastic tube, the hollow element 6. and the second elastic tube, and the body of the device comes to

actuator or signaling device. Depending on the reasons for the break of the rope or thread and the duration of its elimination, compressed air may be disconnected from the sensor or not disconnected. In the latter case, for as long as the harness has been removed, the actuator or alarm device remains in working condition until the harness is reloaded into the probe-harness guide. The guaranteed overlap of compressed air requires that the axes of the elastic tubes and the axis of rotation of the gauge probe are parallel and better in the same plane, and the deviation of the probe guide from the initial position is within 80-120.

The return of the cable harness to its original position can only occur due to the elasticity of the elastic tubes (Fig.6). In this case, the probe-gang-rule (2l can be combined with a hollow element and made of a tube.
