SU500851A1 - The device for determining the position of the rental - Google Patents

Description

one

The invention relates to the field of counter-measuring equipment, mainly to photoelectric non-contact devices (devices for determining the position and size of objects, and can be used, for example, for determining the position of hot-rolled products.

Devices for determining the i-prog position are known, comprising a collimator made in the form of a series of parallel light guide channels, a fiber-optic image transformer and a photo-spectral scanning node. The position of the nepetvnogo end of the rolled product is determined by the number of pulses produced by the photovoltaic node during scanning of the light signals C | 1 of the output ends of the optical fibers of the fiber-optic transformer. The disadvantage of the known device zlt vts is the inaccuracy of the determination of the south of the prosh at its transverse displacement and width change due to the perpendicular alignment of the collimator channels with respect to the direction of rolling. In order to improve the accuracy of

nor the position of the rolled light guide; the collimator channels are positioned so that

One of the diagonals of each channel forms a right angle with the direction of hire.

In FIG. 1, a diagram of the proposed device is shown; in fig. 2 and 3 - the distribution of the channels of the collimator with respect to moving rolling in the proposed and known devices.

The device contains a collnmator 1, made in the form of a series of parallel light-conducting channels 2, | Fiber optic image transformer 3, made up of optical fibers 4, the front ends of which are fixed on the output ends of channels 2, and the rear ones are arranged in the scanning path of the photovoltaic node 5, which can be used, for example, a television tube. The front ends of the 6 channels 2 are located on the same line along the direction of movement of the rental 7. The light-conducting channels 2 of the collimator are located so that one of the diagonals 8 of each channel &

forms a right angle with the direction of rental.

The position of the front end of the rolled product is determined by the number of pulses produced by the photovoltaic node 5 during scanning of the output torn of the optical fibers 4.

Performing the collimator in this way improves the accuracy of determining the position of the front end of the rolled metal in the controlled ion. In this case, the lines of reference, which are a continuation of cyagonpey 8, are located parallel to each other and parallel to the front loudness of the rental. As a result, the cross-sectional mixes of rolled metal, and the change in its width when switching over to another grade or billet, does not indicate kgg I for measurement accuracy.

In determining the position of the front

the edges of the rolling stock 9 by the known ugroup, in which the channels 1O of the windrower are perpendiculum to the direction of movement of the rolled metal, the accuracy will be better due to the presence of the above errors.

Fig. 3 shows that the lateral displacements of the car 9 and the change in its thickness lead to a lack of significance in determining the position of its front end.
