Abstract
The invention relates to a heald raising detection method of an electronic jacquard machine. A Hall sensor, a connecting lead, a raising heald, a magnetic material and a parallel data to serial data conversion element are mainly provided in the detection method, wherein the magnetic material is fixed on the raising heald; and the output end of the Hall sensor is connected with the input end of the parallel data to serial data conversion element through the connecting lead. The invention realizes the complete detection of a heald raising motion state, thereby accurately detecting the accuracy of the needle selecting action of an electromagnetic valve needle selector of the electronic jacquard machine; in addition, compared with the traditional detection method, the invention has higher reliability and can detect whether all the needle selecting actions of the electronic jacquard machine are accurate or not on line.
Description
Technical field
The present invention relates to a kind of heald raising detection method of electronic jacquard machine, it is applied to textile industry.
Background field
Electronic jacquard machine is a kind of weaving that runs up equipment of complexity, has considerable electromagnetic valve needle selection device.Each electromagnetic valve needle selection device, drives corresponding warp and rises or descend in conjunction with mechanical movement by to the absorption of needle with do not adsorb this two states.All electromagnetic valve needle selection devices are worked together, just realize that the part warp rises, and the part warp descends, and forms a specific opening, and parallel passes from this opening, with the warp formation woven fabric that interweaves.
Because electromagnetic valve needle selection device One's name is legion in the electronic jacquard machine, and running speed is fast, substantially all more than 280r/min, and also often 7 * 24 operations, one day needle selection number of times will reach more than one hundred million even tens times, and control requires quite high.The electromagnetic valve selecting needle assembly might lose efficacy, in case lost efficacy, will cause fabric to produce flaw, influence the quality of fabric, so must whether operate as normal detects to electromagnetic valve needle selection device.Present detection method all is an electric circuit inspection generally, that is to say that the characteristic that can only detect electromagnetic valve whether in normal range (NR), can't detect the needle selection mistake of electromagnetic valve randomness; Simultaneously, because the problem of needle or heald, and the needle selection that causes failure, electric circuit inspection can't be judged.
Obviously, effective method is exactly the motion that detects the heald that promotes warp, and the present invention just is based on such thought and proposes.
Summary of the invention
The present invention proposes a kind of detected electrons jacquard needle selecting and whether operates correct method, is applied to textile industry.
Know-why of the present invention is a Hall effect, and when one section magnetic material motion, magnetic field on every side can change, and the magnetic field that changes is converted into the variation of output voltage.The present invention fixes one section magnetic material on heald, heald is after the needle selection running finishes, the warp that promotes is adsorbed by electromagnetic valve owing to corresponding needle, no longer motion, and the corresponding warp that is not adsorbed needle descends along with the decline of needle, at this moment, magnetic material will form the magnetic field that changes in the motion of Hall element annex, and the voltage of Hall element output will change.Like this, just can recognize the motion conditions of specific warp, judge whether the needle selection action is correct according to the voltage output of Hall element.
The present invention is realized by a testing circuit, testing circuit changes the serial data element by magnetic material, Hall element, connection lead, parallel data and forms, magnetic material is fixed on the heald that drives the warp motion, and the output of Hall element is connected with the input that parallel data is changeed the serial data element by connecting lead.
Advantage of the present invention is, Hall element detects the motion of the magnetic material on the heald, the variation of output voltage that can be by Hall element comes perception, the actual conditions of needle selection can be correctly described in such detection, no matter be because the needle selection mistake that the inefficacy of electromagnetic valve needle selection device causes, or the needle selection mistake that causes of the reason of heald, needle, can detect, the technology in the past that solved can only testing circuit, and can not detect the defective of actual needle selection situation.
The specific embodiment
The present invention is further detailed explanation below in conjunction with drawings and Examples.
Referring to Fig. 1, the output of Hall element 1 is connected with the input that parallel data is changeed serial data element 4 by connecting lead 5, magnetic material 2 is serially connected on the heald rope 3, such Hall element 1 has a plurality of, the output of each Hall element 1 links to each other with the input that parallel data is changeed serial data element 4 by connecting lead 5, when heald rope 3 after needle selection running finishes, the corresponding warp needle that promotes is adsorbed by electromagnetic valve, no longer motion, and corresponding decline warp descends along with the decline of needle, at this moment, magnetic material 2 will be in the sensing scope motion of Hall element 1, the motion of magnetic material 2 has produced the magnetic field that changes, and Hall element 1 will detect the magnetic field of variation, thereby the voltage that can cause output changes.Parallel data commentaries on classics serial data element 4 converts the signal of a plurality of inputs arranged side by side to serial signal, by detecting parallel voltage signal, just can recognize the actual motion situation of each root heald rope 3, and then judges whether the needle selection action is correct.
