Problems solved by technology

When measuring the length, the mechanical counter needs to correct the error between the indicated value and the actual value through the transmission ratio or is equipped with a standard measuring roller. The disadvantage is that the operation is complicated and the measurement error is large.
When measuring the length, the electronic length meter not only needs to be equipped with a magnetic induction sensor or a photoelectric sensor and a porous turntable, but also solidifies the diameter of the length measuring shaft in the central processing unit CPU of the length meter in advance. Therefore, a type of electronic length meter It can only be applied to one type of equipment to measure the length of the measured object. Since there are many types of strip-shaped objects that need to be measured in length in industrial production, there are many equipment that need to be counted. Therefore, the corresponding electronic length measuring instrument type Just a lot, its disadvantage is poor versatility, which brings a lot of inconvenience to users

Embodiment Construction

[0019] With reference to accompanying drawing, the length measuring method described in embodiment, comprises the following steps:

[0020] A. Changing the sampling permanent magnet 1 from being installed on the measuring axis 2 to being installed on the sampling axis 3, the installation position of the sensor 8 is also changed from being close to the measuring axis 2 to being close to the sampling axis 3, and the measuring axis 2 passes through The meshed gear set is connected with the sampling shaft 3, and the signal output end of the sensor 8 is connected with the input end of the signal converter 6 in the electronic length meter;

[0021] B. Use the parameter setting button on the panel of the electronic length measuring instrument to input the diameter of the length measuring axis 2 of the strip to be measured, the gear transmission ratio between the length measuring axis 2 and the sampling axis 3 to the electronic length measuring instrument at the measurement site In th...

Abstract

A length measuring method installs the sample permanent magnet on the sample shaft instead of on the length measuring shaft, and installs the sensor to the place close to the sample shaft instead of the length measuring shaft, which connects with the sample shaft through the teethed gear set, connecting the signal output end of the sensor with the input end of the signal converter of the length measuring electrometer, entering the diameter of the strip like length measuring shaft and the gear drive ratio between the sample shaft through the parameter setup button on the length electrometer panel to the CPU of the length measuring electrometer. It can realize the length measurement to all strips like articles along their transmission direction, with strong applicability, simple operation and improved precision.

Description

technical field [0001] The invention relates to a method for measuring the length of a strip-shaped object conveyed along its length direction. Background technique [0002] At present, the instruments used to measure the length of a strip-shaped object transmitted along its length mainly include mechanical counters and electronic length counters. When measuring the length, the mechanical counter needs to correct the error between the indicated value and the actual value through the transmission ratio or is equipped with a standard measuring roller. The disadvantage is that the operation is complicated and the measurement error is large. When measuring the length, the electronic length meter not only needs to be equipped with a magnetic induction sensor or a photoelectric sensor and a porous turntable, but also solidifies the diameter of the length measuring shaft in the central processing unit CPU of the length meter in advance. Therefore, a type of electronic length meter ...
