Embodiment Construction

[0027] Fig. 1 is a perspective view of a use state of a strip conveying device 1 according to a specific embodiment of the present invention. Tape conveying device 1 is contained in sewing machine body (not shown in the figure), and is used when tape (ribbon) T such as lace elastic band and elastic band is sewn on cloth (not shown in the figure), is controlled by conveying device body 2 and Box 3 (as shown in Figure 2) constitutes.

[0028] The conveying device body 2 has a large roller 5 for pinching the strip T, a small roller 6 and a stepping motor 7 for driving the large roller 5 to rotate. The rollers 5, 6 are supported by the roller mounting table 10, and the roller mounting table 10 is fixed to the sewing machine body by the bracket 8, so that the rollers 5, 6 are arranged above the cloth presser 4 of the sewing machine body. The outer peripheral surfaces of the rollers 5 and 6 are roughened by knurling, and they are in elastic contact with each other. Thereby, the ta...

Abstract

The utility model relates to a sewing machine which can automatically check whether a sewing product is stitched according to a specified length. The strip conveying device includes a pair of rollers holding the strip, and the stepping motor drives the large roller to rotate to send out the strip; the pulse signal sent to the stepping motor is sent by the control part; the control part has a recording function sent to the stepping motor The tape conveying pulse recorder of the number of pulses detects the length of the tape sent out; the control unit records the predetermined length of the tape to be stitched, and calculates the difference between the predetermined length and the actual tape sent out after the sewing operation is completed. When the difference of the bar length exceeds the allowable error range, a warning will be issued.

Description

technical field [0001] The present invention relates to a sewing machine, in particular to inspection after sewing. Background technique [0002] Lace elastic at the hem of shorts, girdles, etc.; elastic at the top of pantyhose, bodysuits, etc.; elastic sewing, etc., of swimsuits, sports shorts, etc.; sewing these tapes (hereinafter referred to as tapes) to fabric , the tape is sewn to the fabric while being fed out from the tape feeder installed in the sewing machine. As a conventional technique for sewing a tape to cloth with high precision, there is, for example, Japanese Patent Publication No. 7-44984 "Conveyance control device for long-sized sewn objects in a sewing machine". [0003] In the following, the tape stitching will be described in more detail. The cloth is located on the needle plate, and the tape is delivered from the tape conveying device to the top or bottom of the cloth. The operator sews the tape while feeding out the cloth such that the tape is sewn a...
