Problems solved by technology

Since the stack of cutting pieces placed on the cloth placing table is directly moved from the cutting bed, it is very likely that a stack of cutting pieces will be mixed with shorter length secondary materials. The function of rejecting short remnants, which in turn affects the performance of automatic sewing equipment

Embodiment 1

[0043] Embodiment one, as Figure 1 to Figure 4 As shown, the sewing material detection sensor 1 is installed at the channel opening 51 and is fixed on the lower end side of the table 5 . At this time, the sewing material detection sensor 1 can be a through-beam photoelectric sensor, which has a transmitting part 11 and a receiving part 12 that are independent from each other and arranged opposite to each other left and right, such as Figure 4 As shown, the transmitting part 11 and the receiving part 12 are all fixed on the mounting bracket 2, and the two mounting brackets 2 are installed on the left edge and the right edge of the channel opening 51 respectively, and are fixed on the lower end surface of the platen 5, and then the The sewing material detection sensor 1 is installed at the passage opening 51 places. Alternatively, the sewing material detection sensor 1 can also be a reflective photoelectric sensor, such as Figure 5 As shown, the sewing material length detec...

Embodiment 2

[0045] Embodiment two, such as Figure 6 and Figure 7 As shown, the sewing material detection sensor 1 is installed on the lower end surface of the right end of the platen 5, and is adjacent to the channel opening 51, and the platen 5 is provided with a through hole 52 that penetrates up and down and exposes the seam material detection sensor 1; at this time , The sewing material detection sensor 1 is a reflective photoelectric sensor. Since the sewing material detection sensor 1 is installed on the lower end surface of the right end of the table 5, when the sewing material clamping device 3 transfers the sewing material to the specified position on the table 5, the sewing material must go over the sewing material detection to the left. The sensor 1 makes the table 5 must be able to accommodate a whole piece of sewing material, thereby relatively increasing the length of the table 5 and the overall length of the automatic sewing equipment. However, since the movement of the...

Abstract

The invention provides a sewing material length detection device of automatic sewing equipment. The sewing material length detection device is used for detecting length of a sewing material clamped by a sewing material clamping device, the sewing material clamping device can move between a cloth placement platform and a platen in the automatic sewing equipment and clamps one end of the sewing material in the length direction, the sewing material length detection device comprises a sewing material detection sensor used for detecting whether the sewing material passes or not, and the sewing material detection sensor is arranged on a moving track of the sewing material clamping device. Whether the sewing material passes or not is detected through the sewing material detection sensor to acquire time points when the sewing material passes the sewing material detection sensor along the length and two ends of the sewing material respectively, and the length of the sewing material can be calculated by combining with moving speed of the sewing material clamping device, so that powerful data support is provided to an electric control module in the automatic sewing equipment to automatically judge whether the sewing material is a defective material or not, and sewing efficiency and quality of the automatic sewing equipment are guaranteed finally.

Description

technical field [0001] The invention relates to a sewing material length detection device of automatic sewing equipment. [0002] The present invention also relates to an automatic sewing device comprising the above-mentioned sewing material length detection device. Background technique [0003] At present, automatic sewing equipment usually includes a cloth placing table, a separation unit, a clamping unit, an alignment unit, a sewing unit, and a receiving unit, wherein the cloth placing table is used to place a stack of cutting pieces moved from the cutting bed ;The separation unit is used to separate a stack of cutting pieces layer by layer and separate the sewing materials; the clamping unit is used to clamp the separated sewing materials and transfer the sewing materials to the designated position on the table; the alignment unit It is used to align the edges of the sewing materials on the table to avoid inclination at the end of the sewing materials near the sewing un...
