Abstract
The invention relates to an automatic edge control device of an industrial sewing machine. The automatic edge control device comprises a platform, and a pressing plate is fixedly arranged on the platform. The feeding direction of sewing material is the X direction, and the direction perpendicular to the horizontal direction is the Y direction. A motor and an electromagnet are fixedly arranged on the lower portion of the platform, the motor drives a synchronous belt to rotate, the synchronous belt is installed on a rigid rocker arm, an ejector rod of the electromagnet ejects the rigid rocker arm up, the upper end of a ratchet presses cloth on the lower end face of the pressing plate, and friction force between the sewing material and the pressing plate is much smaller than that between the ratchet and the cloth. A pair of photoelectric switches are arranged at the parts, close to the sewing portion, of the platform in the Y direction; when the photoelectric switch on the inner side can not detect the sewing material, the motor works in the forward direction, and the synchronous belt drives the ratchet to rotate in the forward direction so that the sewing material can move outwards. When the photoelectric switch on the outer side senses the sewing material, the motor works in the backward direction, the synchronous belt drives the ratchet to rotate in the reverse direction until the photoelectric switch on the outer side can not sense the sewing material, and then the motor stops working.
Description
Technical field
The present invention relates to a kind of industrial sewing machine, specifically, be that a kind of industrial sewing machine controls limit device automatically, belong to industrial sewing machine control limit technical field.
Background technology
Existing industrial sewing machine, in the process of tailoring cloth edge sewing, what have carries out control limit according to " backer ", and some dependence computer programs and servomotor control track of sewing.
When cloth edge to be made is form of straight lines time, adopt " backer " to align, manually can control limit, effect also can reach general requirement.But when when the cloth edge made is the track of circular arc or other irregular lines, adopt the difficulty on manually control limit comparatively large, it is poor to make effect, and uniformity is lower.
And rely on computer program and servomotor to control the mode of sewing track, cost drops into larger, be applicable to the batch production of privileged sites, the out pocket of such as shirt pocket, and for some customization, non-bulk dress ornament, or the edge with irregular curve that personalization level is higher, then computer program and servomotor generally cannot be used to control track of sewing.
Summary of the invention
The object of the invention is: a kind of automatic control limit device being applicable to industrial sewing machine being provided, when making the cloth at irregular curve edge, can realizing automatically controlling limit, improve the quality and uniformity of making, reduce the labour intensity of workman, guarantee that scheme has economical, feasibility simultaneously.
The present invention takes following technical scheme:
A kind of industrial sewing machine controls limit device automatically, comprises platform, described platform is fixedly installed holding pad 6; Sewing direction of feed be X to, the direction of horizontal vertical is Y-direction with it; Described platform lower is fixedly installed motor 2, electromagnet 4, driven by motor Timing Belt 5 rotates, Timing Belt 5 is arranged on rigid swing arm 7, the push rod of electromagnet 4 is by rigid swing arm 7 upwards jack-up, cloth is pressed on the lower surface of holding pad 6 by the upper end of ratchet 3, and the frictional force between sewing and holding pad 6 is much smaller than frictional force with cloth of ratchet 3; Described platform is closely made position and be provided with a pair optoelectronic switch 1 along Y-direction, when inside light electric switch can't detect sewing, motor forward works, and drives ratchet 3 to rotate forward, sewing outwards movement by Timing Belt 5; When external side light electric switch senses sewing, motor 2 reverse operation, drives ratchet 3 to rotate backward by Timing Belt 5, until when the induction of external side light electric switch is less than sewing, motor 2 quits work.
Further, the thrust of described electromagnet 4 can regulate according to electrical current, and then adjustment regulates the thrust between ratchet 3 and sewing according to the kind of sewing.
Further, described rigid swing arm 7 is fixedly connected with connecting plate, and the push rod of described electromagnet 4 promotes described connecting plate and drives rigid swing arm 7 to rotate.
Further, described platform is provided with the waist-shaped hole fixing a pair optoelectronic switch 1, and the spacing of described a pair optoelectronic switch 1 can regulate in the length range of described mounting hole, and then adjustment control limit precision.
Beneficial effect of the present invention is:
1) when making the cloth at irregular curve edge, realize automatically controlling limit.
2) improve the quality of making and uniformity.
3) labour intensity of workman is reduced.
4) structure is simple, and drop into little, have economical, exploitativeness is high.
