Abstract

The utility model relates to a linear needle position detecting device of a computer embroidering machine and belongs to the field fabric detecting device. The utility model mainly comprises a detecting device stand. A color changing convex wheel driven by electric motor is arranged on the detecting device stand. The utility model also includes a sliding shaft, a guiding shaft and a linear needle position detecting plate which is arranged in the right front parallel with the guiding shaft; a hall element is arranged uniformly and side by side at the position corresponding to each needle line on the detecting plate; an electromagnet which is used for detecting is installed on the sliding body. Decoding and driving part of the detecting circuit is installed at side of the detecting device stand. Detecting can not limited by structure because of adopting a line detecting method and the circuit can be broadened unlimitedly, thus maximum amount of needle position is not restricted.

Description

Computer embroidering machine straight line pin level detecting apparatus

(1) technical field

The utility model belongs to textile machine checkout equipment field, specially refers to a kind of computer embroidering machine straight line pin level detecting apparatus that is used for.

(2) background technology

Anglicanum and bright and colourful product thereof, just spread among the people in China from ancient times, be subjected to the praise in the world, long history in thousand is arranged so far, after modern age, high-tech means was infiltrated embroidery industry, further strengthened especially, present the wide prosperous market prospects that expand, in recent years, China grasps and has used the computerized emboridering machine serial equipment, improved the embroidery process efficiency fully, and, embroidery machine expands to and can drive tens heads simultaneously from driving a head, improved work efficiency greatly, the computerized emboridering machine of an early stage generation derives from import equipment, the fuselage complexity, huge, cost an arm and a leg, the national conditions that can not adapt to China's widespread usage, especially for checkout gear, in the computer embroidering machine course of work, embroider pin position and embroider line color in order accurately to control each head, to detect the pin position, again signal being passed to computer is controlled, in the operation, the checkout gear of having experienced is science not to the utmost, rationally, not only its detection range is limited to constantly, inconvenient operation, and the checkout gear complex structure, the material cost height, cost is expensive, with reference to Fig. 1, represent original circumference formula checkout gear,, realize the detection of pin position by 2 motions of gear 1 driven gear, measuring electromagnet is housed on the gear 2, the testing circuit plate is contained in the parallel plane of gear, along uniform Hall element on the circumference of the electromagnet place circular diameter of gear 2 in order to detecting the pin position, original this one week of scheme at most even 9 Hall elements of cloth, otherwise hypotelorism can disturb, if increase the radius of gear 2, not only the cost height has also destroyed the complete of profile, under the situation of this many defectives, this development group proposes a kind of science more from operation principle and practicality, the orthoscopic pin level detecting apparatus of being convenient to operate has improved a new step with the general function of computer embroidering machine.

(3) summary of the invention

In order to overcome on existing computerized embroidery equipment, to existing detection range to be limited in its original circumference formula pin level detecting apparatus use, the degree of accuracy can not meet the demands and the testing equipment complex structure, many defectives such as involve great expense, and redesign a kind of straight line pin level detecting apparatus, the technical scheme of taking for addressing the above problem is as follows, a kind of computer embroidering machine straight line pin level detecting apparatus, mainly comprise the checkout gear frame, install on it by motor-operated colour changing cam, sliding axle, the axis of guide, reciprocating slide mass and the electromagnet that is used to detect on the axis of guide, it is characterized in that, the dead ahead parallel with the axis of guide, straight line pin position probing plate is housed, corresponding each pin position of this check-out console, settling corresponding even Hall element side by side, device has the electromagnet that detects usefulness on slide mass, and the decoding of testing circuit plate and drive part are contained in the side of checkout gear frame.

In the work, when computer embroidering machine needs colour changing, motor drives colour changing cam rotation, cam is transformed into rectilinear motion with circular motion, each head that drive is fixed on the sliding axle does reciprocating linear motion, roll sleeve in the cam path drives slide mass and carries out move left and right, when the Hall element on electromagnet on the slide mass and the pin position check-out console over against the time checkout gear notify the computer generation signal that colour changing puts in place, the Hall element that electromagnet is corresponding different, promptly arrive different colour changing positions, thereby realized embroidering the function of pin position probing.

Described sliding axle, being installed with can be by 1 to 36 different number by the head number that head drove that sticks with the embroidery pin of this drive.

The evenly Hall element of settling on the check-out console of described pin position side by side, the figure place that it can the respective row pin.

The beneficial effects of the utility model are, because what adopt is the straight-line detection mode, spatially be not subjected to structural limitations, the realization of circuit can infinitely be widened, thereby the maximum needle position that can detect is unrestricted, if also will continue to expand large needle position, only needing directly increases the relevant detection control circuit, and need not consider the influence of mechanism driving chain on the space layout by 8421 coded systems, also just need not to increase volume, thereby cost is also more economical than other schemes.

(5) specific embodiment

With reference to Fig. 1, represent a computer embroidering machine appearing diagram, the checkout gear frame is 1, be subjected to the head 2 that sliding axle drives on the frame, in model is on the NP-CEM1206 embroidery machine, the head number is 6, every head contains 12 embroiders pin, with reference to Fig. 4, along the moving a plurality of heads of sliding axle 6 synteny, straight line pin position check-out console 3 place frame by under the position, the middle part of frame 1 is a colour changing cam 4, it moves in a circle along camshaft 5, slide mass 7 slides along the axis of guide 9 by ball bearing 8, is connected to electromagnet 11 on the slide mass, in the sliding process when the position of magnet 11 just in time with the position that is located at the Hall element 10 on the check-out console when last, just can send the signal that colour changing puts in place, finish measuring ability to computer.With reference to Fig. 5, be 12 pin position computer embroidering machine straight line pin level detecting apparatus circuit diagrams, wherein Hall element 10 has 12 label is 2-13 with to embroider the pin number identical, and detection signal exports computer to after through transistor A10LS signal being amplified, and provides operation information.
