Problems solved by technology

[0003] In order to overcome the shortcomings of the existing technology such as narrow measurement range, poor stability, susceptibility to environmental interference, complex installation, large investment, and inability to fix the width to realize the positioning and shearing function, etc., which are not suitable for the current medium plate shearing process requirements, And the deficiencies such as many input manpower, cumbersome measurement process, low measurement accuracy and incomplete data record in static instrument measurement or manual measurement; the present invention provides an automatic On-line length measurement system, which not only has a large measurement range, good stability, and is not susceptible to environmental interference, but also is easy to install, has a small investment, and can realize positioning cutting and automatic length and width recording functions.

Embodiment Construction

[0025] Below in conjunction with accompanying drawing, non-limiting embodiment of the present invention is described in further detail as follows:

[0026] Such as figure 1As shown in the signal flow chart, in the automatic judging device (1), the photoelectric switch device is composed of a photoelectric switch (6) and a photoelectric reflector. The photoelectric switch (6) is installed on the shearing machine body, and its photoelectric reflector is installed on the roller The bottom is opposite to the photoelectric switch (6), and there is no cable between them. The photoelectric switch (6), the equipment action auxiliary part (7) are connected with the intermediate relay (8), and are connected with the remote I / O acquisition template (9) through it. The photoelectric switch (6) and equipment action auxiliary parts (7) are used to judge and control the action signals of production equipment such as shears (32) or middle plates, and are converted into action data signals b...

Abstract

An in-line automatic length measuring system for measuring the length and width of intermediate plate is composed of laser measurer with cooler, the automatic judger consisting of photoelectric switch, action aid, relay and I / O card, the locating shearer with digital size indicator, data acquiring and processing unit comprising data acquisition card, RS232 port, bus and industrial control computer, and data network manager. Its advantages are high measuring correctness, low cost, and high automation level.

Description

Technical field [0001] The invention relates to an automatic on-line length measurement system, in particular to an automatic on-line length measurement system applied to a mid-plate positioning and shearing production line. Background technique [0002] After the medium plate is finished, the dynamic automatic measurement of the length and width of the medium plate on the medium plate positioning and shearing production line has always been a difficult problem. At present, some existing technologies use the critical angle measurement method or lens laser measurement method for online measurement, which has narrow measurement range and poor stability, and the measurement is susceptible to environmental interference, which is not suitable for the current medium plate shearing process, and there are too many application equipment And the installation is complicated, the investment is large, and the positioning and shearing function cannot be realized; and it is difficult to so...
