Device and method for automatically measuring quantity and length of cloth

Abstract

According to the device for automatically measuring the number and the length of the cloth, the traction wheel, the tensioning mechanism and the measuring mechanism are sequentially arranged on the base from left to right, and the measuring mechanism comprises the first connecting frames which are oppositely arranged front and back and the first rolling roller and the second rolling roller which are rotationally installed between the first connecting frames. Cloth sequentially passes through the traction wheel, the tensioning mechanism and the measuring mechanism, the cloth enters a rolling gap between the first rolling roller and the second rolling roller, the rotating shaft drives the roller type meter counter to rotate in the rolling process, the roller type meter counter is used for recording the length of the cloth, and when the tail end of the cloth is separated from the first rolling roller, the cloth is taken out. When the monitoring plates on the first rolling roller do not make contact with the cloth any more, the first pressure sensor is used for monitoring the stress condition of the monitoring plates, when all the monitoring plates in the first rolling roller are in a non-stress state, the single-chip microcomputer controls the brake mechanism to enable the rotating shaft to stop rotating, and the roller type meter counter also stops metering; therefore, the length of the cloth is accurately measured.

Description

technical field [0001] The invention relates to the field of piece quantity and length measurement, in particular to a device for automatically measuring the quantity and length of cloth pieces. Background technique [0002] The current method of detecting the number and length of cloth generally relies on manually counting the number and measuring the length, and after manually writing the code list, the computer counts; the manual measurement method is not only time-consuming and laborious, but also prone to measurement errors. [0003] Announced on August 29, 2012, the Chinese invention patent with the announcement number CN102226679B discloses a method for automatically measuring the number and length of cloth. However, traditional meter counters are generally attached to the rollers. During the process of cloth transmission, the rollers will generate inertial force. When the cloth has been detached from the rollers, the rollers will still rotate, resulting in the length...

[0003] Announced on August 29, 2012, the Chinese invention patent with the announcement number CN102226679B discloses a method for automatically measuring the number and length of cloth. However, traditional meter counters are generally attached to the rollers. During the process of cloth transmission, the rollers will generate inertial force. When the cloth has been detached from the rollers, the rollers will still rotate, resulting in the length recorded by the meter counter. Deviation
