Coding device and coding method of print wheel of numbering machine

Abstract

The invention discloses a coding device of a print wheel of a numbering machine, which comprises one or more print wheels around the circumference of which more than 2<n-1> and less than or equal to 2<n> print characters are distributed, wherein n is natural number more than 1; sensor units are arranged close to the circumferences of the print wheels and the print wheels are provided with a plurality of magnetic elements for transmitting magnetic signals to the sensor units; each sensor unit corresponding to each print wheel comprises n-1 sensor elements continuously arranged according to the angle intervals along the circumference direction of the print characters on each print wheel; the magnetic elements include magnetic elements of positive and negative two polarities; the sensor elements comprises two kinds of effective sensor elements triggered by the magnetic elements of positive and negative two polarities; the device also comprises a computer processor superposing the former character codes and the character codes after jump of sensor elements, the magnetic elements and the sensor elements are distributed in a mode that when the codes of a plurality of print characters detected by the n-1 sensor elements are the same, the codes of print characters before the characters having the same code are different. The device solves the problems of the prior coding device such as a large number of sensor elements required for the realization of full codes of the characters and consequent small spatial place of the numbering machine.

Description

technical field [0001] The invention relates to an encoding device, in particular to an encoding device for a character wheel of a numbering machine. Background technique [0002] The numbering machine is a machine that prints marks in the printed matter. The numbering machine is divided into rotary type and platform type according to the operation mode. It is used for different printing machines. Each printing machine is equipped with different numbers of numbering machines according to the requirements of the printed matter. From one Taiwan to dozens of Taiwan. The numbering machine is composed of different numbers of character wheels. The number of character wheels is determined according to the number of digits of the printed mark. Ten digits are commonly used, ranging from one to tens of digits. Printed marks can also be designed and engraved arbitrarily, such as: Arabic numerals, Chinese numerals, English letters, graphics, barcodes, multi-dimensional codes, etc., and...

AI Technical Summary

Problems solved by technology

[0022] The present invention aims to solve the coding device of the existing numbering machine, which is less than or equal to 2 n , greater than 2 n-1 The digit wheel needs to set n Hall elements to realize the corresponding ≤2 n , > 2 n-1 The full coding of digits, the setting of n hall elements will limit the technical problems of the installation of other mechanical structures
