Abstract
The utility model relates to a thread breakage sensor for a sewing machine, which comprises a thread holder, wherein the potential of a thread take-up spring which is installed on the thread holder is low, and a metal contact piece which is adjacent to the thread take-up spring is connected with a high potential. The thread take-up spring contacts the metal contact piece in free state. The utility model skillfully uses the sewing tension which is borne by the existing thread take-up spring of a sewing machine on the occasion of sewing. The thread take-up spring for thread breakage comes back into the existing state and contacts the metal contact piece once the sewing control is lost. Just the metal contact piece and a connecting thread of the high potential are added, signals are accurate and reliable, and the cost is reduced largely.
Description
Technical field:
The utility model belongs to sewing machine technique, particularly to the disconnected sensor of not monitoring of suture.
Background technology:
Existing Sewing machines in the course of the work, particularly in automatic clothing product line, often the broken string phenomenon takes place in order, generally finds and the eliminating fault by manually going.Existing a kind of automatic photoelectric sensor is oppositely arranged by luminous tube and receiving tube, and sewing thread passes from the centre, in case break, light receiving tube will induce disconnection signal, sends alerting signal by control circuit.But the market price of this a pair of light pipe is more expensive, and with respect to a Sewing machines price, this cover cost ratio that sensor device produced is too high.
Summary of the invention:
The purpose of this utility model provides a kind of cheap, reliable Sewing machines line-breakage sensor.
The utility model comprises tension disk, and the yarn take-up spring that it is characterized in that being contained on the tension disk is an electronegative potential, and the metal contact of close yarn take-up spring is high potential in succession, and yarn take-up spring contacts with the metal contact when free state.
The utility model has utilized the original yarn take-up spring of Sewing machines the time to be subjected to the tension force of suture and deformation in sewing dexterously, in case the broken string yarn take-up spring is promptly controlled and recovered original form and contact with the metal contact because of losing suture.The utility model has only increased metal contact and high potential line, can realize the informing function that breaks by suggestion device, signal accurately and reliably, cost reduces significantly.
Description of drawings:
Fig. 1 is the utility model embodiment normal condition schematic diagram when work.
Fig. 2 is the utility model embodiment broken string situation schematic diagram when work.
The specific embodiment:
With reference to Fig. 1.Yarn take-up spring 4 is installed on the tension disk 3, yarn take-up spring 4 free states are levels, when when work sewing thread 2 pass from line transfer bar 1 and after yarn take-up spring 4 links, get back to line transfer bar 1, yarn take-up spring 4 is stressed upwards to be triggered, utilize the elastic force of yarn take-up spring 4, the rate of tension of suture 2 when increasing sewing.Because yarn take-up spring 4 and body mechanical connection have the zero potential identical with body.
With reference to Fig. 2.In yarn take-up spring 4 free state positions metal contact 5 is set, both are contacted.A high potential signal V is connected on the contact 5 by current-limiting resistance 6.
When sewing thread 2 was disconnected, yarn take-up spring 4 lost the power of colluding and the state position and contact with contact 5 of affranchising, and made contact 5 change to zero potential from high potential.As long as take out the control end that contact 5 signals are linked on-off circuit, can realize breaking and inform by known technology.
