Abstract
This single chain stitch sewing device is provided with a sewing mechanism provided on a front end arm of a delivery robot. The sewing mechanism comprises a sewing motor for supplying power to sewing needles and loopers. When the sewing motor is energized, power is transmitted to the sewing needles via a first power transmission mechanism, this causing the sewing needles to move reciprocally. At the same time, power is transmitted to the loopers via a second power transmission mechanism to rotate the loopers. Accordingly, sewing is performed. The loopers are provided at an end of a post bed on the side closer to the sewing needles.
Claims7
A single chain stitch sewing device comprising:
- a sewing mechanism that includes a needle configured to repeatedly make reciprocating motion to thereby be stuck into and retracted away from a workpiece, and a looper facing the needle across the workpiece, the sewing mechanism being configured to form stitches on the workpiece with the needle and the looper, wherein
- the sewing mechanism further includes:
- a power source configured to rotate the looper and simultaneously reciprocate the needle;
- a crank configured to transmit power of the power source to the needle;
- a power transmission mechanism that is at least partially housed in a post bed and configured to transmit the power of the power source to the looper;
- and
- a first gear and a second gear that are provided in the post bed as constituent elements of the power transmission mechanism and configured to mesh with each other, and
- the looper rotates together with the second gear and is provided at a tip of the post bed that faces the needle,
- wherein the needle comprises two needles, and the looper comprises two loopers;
- and
- the second gear is located between the two loopers.
