Abstract

The invention discloses a method for detecting bead conveying. A second detector is arranged for detecting travel of a bead conveying plate, the second detector is provided with any one detecting point, the detection point detects travel information of a point on the bead conveying plate in bead conveying travel, and a control system determines travel difference between the bead conveying plate and a driving motor, and further drives the driving motor to make corresponding response based on a determining result by receiving the travel information of one detecting point detected by the second detector, and comparing the travel information with preset travel information of rotation of the driving motor of a first detector, so as to enable the bead conveying plate to convey beads to be directly under an embroidery needle more quickly and accurately. The method has the beneficial effects that the method and the device disclosed by the invention achieve simultaneous monitoring and comparison of travel difference between the first detector and the second detector through the control system, and can effectively perceive and avoid the out-of-step phenomenon caused by factors such as instability of the driving motor or / and the change of a friction coefficient of a bead conveying structure, thereby avoiding the problems of needle striking, bead splashing, bead missing and the like.

Description

technical field

[0001] The invention relates to a bead embroidery machine head or a method for detecting beads sent by a bead embroidery machine. Background technique

[0002] Bead embroidery puts loose beads through the bead guide rod through the bead stringing device, and the bead feeding device of bead embroidery conveys the beads on the bead guide rod one by one to the place directly below the embroidery needle of the embroidery machine, so that the beads match the embroidery needle, and the embroidery The needle secures the beads to the fabric through the thread.

[0003] The bead feeding device includes a base plate with a guide groove, a bead feeding structure that slides in the guide groove of the base plate, a driving motor for driving the clamp of the bead feeding structure, and feeding beads. Usually, in order to facilitate accurate bead feeding, a detector is provided on the driving motor of the bead feeding, and the detector is used to detect the rotation angle...

Examples

Embodiment Construction

[0023] see Figure 1-7 , this implementation case, a method for detecting beads by a bead-feeding device, setting a control system, setting a closed-loop connection with the control system on the drive motor of the bead-feeding structure 1 that grips and transports beads, and detecting the rotation angle of the drive motor 11 or The first detector 2 in the rotating position is provided with the second detector 3 connected to the control system to detect the bead delivery stroke information of the bead delivery structure 1, and the second detector 3 can arbitrarily set detection points within the normal bead delivery stroke, and the control system receives The stroke information of the detection point detected by the second detector 3 is compared with the preset stroke information rotated by the drive motor 11 of the first detector 2 to judge the stroke difference between the bead feeding plate 12 and the drive motor 11, and then judge whether there is a step-out situation, Whe...
