Abstract
The invention relates to a rotary coder of an offset press, in particular a rotary coder of a hall-type offset press. The rotary coder of the hall-type offset press consists of a magnet combination (1), a sampling circuit (2) and a signal processor (3), wherein the magnet combination (1) is connected with the sampling circuit (2) which is connected with the signal processor (3). The rotary coder of the hall-type offset press has the advantage of a switch-type hall sensor, is designed based on the simple and practical principle to directly obtain the position signals and is different from a magnetic rotary coder with complex and precise structure on the principle. The system acquires better effect on the application of the offset press, has stable and reliable performance and excellent cost performance. The more the sampling points are, the obvious the excellence is for position measurement.
Description
Technical field:
The present invention relates to a kind of scrambler, especially relates to a kind of Hall-type offset press rotary encoder.
Background technology:
The program control system (PLC) that realizes the offset press printing technological process needs with a plurality of sensors paper position, the anglec of rotation to be detected, increasing to installation, debugging and use of number of sensors causes inconvenience, the reliability of equipment is reduced, and the cost of electric control system increases.Analyze the function and the machine driven system of offset press and find, the combined pressure of offset press, beat sign indicating number, dial-up, dust and two revolute function belongs to sequential control, can be by the anglec of rotation of detection collection roller, the realization programmed control.Consider that offset press exists oil, China ink, water and dust fall to pollute, belong to the harsh applied environment of operation continuously again, the magnetic sensitive sensor is comparatively suitable, but concerning the few relatively offset press of control station, selects for use magnetic rotary encoder to seem again and cost an arm and a leg.
Summary of the invention:
The purpose of this invention is to provide a kind of Hall-type offset press rotary encoder, it has the advantage of Hall switch sensor, and it directly obtains position signalling based on simple and practical principle design, and is different with the magnetic rotary encoder of complex structure precision on the principle.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it is made up of magnet combination 1, sample circuit 2, signal Processing 3; Magnet combination 1 is connected with sample circuit 2, and signal Processing 3 is connected with sample circuit 2.
Rotary magnet aggregate erection of the present invention is on offset press collection roller, and Hall rotary encoder circuit part is fixed on the body, and sensitive area is aimed at magnetic pole, apart from less than 5mm, the anglec of rotation of collection roller is taken a sample between the two.Because of determining the position of magnetic pole, so sampled signal is the absolute position amount.If sample circuit has the ability at identification typography starting point and sequence of positions reference mark, Yin Shua process just can realize programmed control by the multidraw of a sensor so.The basis of sampling is based on Hall circuit A3144, and obvious single Hall chip can not realize comprising the sampling of starting point and order point, need carry out particular design to sample circuit, with full above-mentioned requirements.The position signalling feed signals treatment circuit that sample circuit obtains carries out judgment processing through software systems to signal, confirms the back output coding information.
The present invention has following beneficial effect: have the advantage of Hall switch sensor, it directly obtains position signalling based on simple and practical principle design, and is different with the magnetic rotary encoder of complex structure precision on the principle.The application of this system on offset press obtained better effects, and be stable and reliable for performance, has the excellent ratio of performance to price.To position measurement, sampling spot is many more, and its superiority is obvious more.
Description of drawings:
Fig. 1 is a theory structure synoptic diagram of the present invention.
Embodiment:
Referring to Fig. 1, this embodiment by the following technical solutions: it is made up of magnet combination 1, sample circuit 2, signal Processing 3; Magnet combination 1 is connected with sample circuit 2, and signal Processing 3 is connected with sample circuit 2.
