Abstract
The utility model belongs to the technical field of sewing machines and particularly relates to a bottom line detecting mechanism of a sewing machine. A shuttle peg is arranged in a shuttle shell in a rotating mode. A light absorbing part is arranged on the side wall of the shuttle peg. A photoelectric sensor used for detecting the light absorbing part is arranged on one side the shuttle shell and controls motion of a servo motor. The bottom line detecting mechanism of the sewing machine is simple in structure, safe, reliable, good in practicality and capable of monitoring a bottom line in real time through the coordination of the photoelectric sensor and the light absorbing part on the surface of the shuttle peg.
Description
Technical field
The utility model belongs to the sewing machine technique field, is specifically related to a kind of bobbin thread for sewing machine testing agency.
Background technology
During Sewing machines work, shuttle coordinates bottom line and reaches the standard grade with lockstitch on fabric with syringe needle, shuttle is comprised of bobbin case and peg or spindle, peg or spindle is arranged in bobbin case, the bottom line winding is on peg or spindle, so the length of bottom line is (being generally that 20m is to 50m) be restricted, therefore, the bottom line of having to change frequently, the less sewer of a few thing experience can not find the phenomenon that bottom line is finished in time, if do not stop in time the sewing process when bottom line is finished, can cause on fabric and produce the empty needle eye, have a strong impact on quality and (the particularly high-grade fur fabric) attractive in appearance of textile product, reduced the qualification rate of textile product.
On market, also there is the Sewing machines of part top grade to there is bottom line supervising device (for example ZL 02128564.0 disclosed on double-lock type stitch sewing machine the device of monitoring and controlling bobbin thread), but the expensive shortcoming of this series products.
Summary of the invention
In order to overcome above shortcomings part in prior art, it is a kind of simple in structure, safe and reliable that the purpose of this utility model is to provide, and cost is lower, and practicality is good, the bobbin thread for sewing machine testing agency easily accepted for market.
In order to reach above-mentioned purpose, the utility model adopts following concrete technical scheme:
Bobbin thread for sewing machine testing agency, peg or spindle rotates and is arranged in bobbin case, on the sidewall of peg or spindle, is provided with light absorption unit, and bobbin case one side is provided with the photoelectric sensor that detects described light absorption unit, and photoelectric sensor is controlled the action of servomotor.
Preferably, be provided with the automatic shutdown circuitry of protection fabric in described photoelectric sensor, automatic shutdown circuitry is controlled the signal break-make of floor push to servo-driver.
Preferably, described automatic shutdown circuitry is connected with floor push with servo-driver by the DB syringe needle.
Preferably, described light absorption unit is extinction enamelled coating or extinction rete or blackout section.Light absorption unit is two sector regions, is symmetricly set on peg or spindle.
Preferably, be provided with the notch of at least one on described bobbin case, the light absorption unit on peg or spindle coordinates with described notch.
Preferably, described photoelectric sensor is integrated with generating laser and receiving transducer.

The specific embodiment
As shown in Fig. 1-4; bobbin thread for sewing machine testing agency; peg or spindle 2 rotates and is arranged in bobbin case 1; be provided with light absorption unit 21 on the sidewall of peg or spindle 2; bobbin case 1 one sides are provided with the photoelectric sensor that detects described light absorption unit; photoelectric sensor is controlled the action of servomotor; in the present embodiment; be provided with the automatic shutdown circuitry of protection fabric in photoelectric sensor; automatic shutdown circuitry is controlled the signal break-make of floor push to servo-driver; when floor push is stepped on, but peg or spindle is not while rotating, and automatic shutdown circuitry is controlled servomotor by servo-driver and shut down.
Preferably, described automatic shutdown circuitry is connected with floor push with servo-driver by the DB syringe needle.The floor push of the Sewing machines on market and servo-driver connect with the DB9 syringe needle between the two, and the pedal side is the DB female, and the servo-driver side is the DB male; The automatic shutdown circuitry of this mechanism is connected with floor push with servo-driver by the DB syringe needle equally, and this design makes producer without the original parts of change, and the strong adaptability of this mechanism, meet market discipline.
Preferably, described light absorption unit 21 is extinction enamelled coating or extinction rete or blackout section.Light absorption unit is two sector regions, is symmetricly set on peg or spindle 2.
Preferably, be provided with the notch 11 of at least one on described bobbin case 1, the light absorption unit 21 on peg or spindle coordinates with described notch 21.This design can effectively improve the practical effect of photoelectric sensor; avoid the interference of external environment condition; the working environment of protection peg or spindle; photoelectric sensor is integrated with generating laser and receiving transducer; the generating laser Emission Lasers is to the peg or spindle surface at notch 11 places, and peg or spindle rotates the light absorption unit and the normal surface that cause peg or spindle and early switches in notch.
The photoelectric sensor collection is launched and is received in one, detects distance and can be regulated as requested.This sensor have detection range far away, be subject to visible ray to disturb little, low price, be easy to assembling, the characteristics such as easy to use.
Preferably, on described photoelectric sensor, automatic alarm circuit is set, is provided with warning lamp on automatic alarm circuit, warning lamp can lead to sewing machine frame top by wire.
During the floor push conducting, give photoelectric sensor an enabling signal, the generating laser Emission Lasers of photoelectric sensor is to the peg or spindle surface, rotation along with peg or spindle, laser coordinates the rotation that realizes the Real-Time Monitoring peg or spindle with light absorption unit, peg or spindle stops operating or rotating speed is down to setting range, illustrates that bottom line uses up, and need to be changed.
Finally it should be noted that: above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
