Abstract: A sewing device includes a power source, an input shaft to which a driving force from the power source is transmitted, an output shaft that outputs the driving force transmitted to the input shaft, and a transmission mechanism that transmits the driving force from the input shaft to the output shaft, in which the transmission mechanism includes a first gear that is provided in the output shaft and rotates integrally with the output shaft, a second gear that meshes with the first gear, an intermediate shaft that rotates integrally with the second gear, and a timing belt stretched between the input shaft and the intermediate shaft, in which the second gear is disposed to be movable in a circumferential direction of the first gear. As a result, loosening of the timing belt can be adjusted in a compact configuration.

Abstract: There is provided a sewing device comprising a needle and a looper, the sewing device including a rotation shaft that rotates the looper, and a set bolt that has a conical distal end and positions the looper in an axial direction relative to the rotation shaft from a radial direction of the rotation shaft, in which the looper includes a through screw hole into which the set bolt is screwed, the rotation shaft includes a groove recessed from a peripheral surface of the rotation shaft, and the groove includes an inclined surface that the distal end of the set bolt contacts. In one aspect, in the sewing device, a cross section of the groove viewed in a direction along an axis of the rotation shaft has a V shape. As a result, a relative position between the needle and the looper can be positioned with significantly high accuracy.

Abstract: A clamping device includes a cylinder, a base body, a movable plate, and holding pins. The movable plate is attached to the base body substantially parallel thereto via two pairs of link arms. The movable plate moves along the operating direction of the cylinder. The movable plate can abut against a width-direction side surface of a workpiece. The holding pins are attached to the movable plate. The holding pins abut against an upper portion of the workpiece.

Abstract: Provided are: a sewing device provided with a sewing mechanism which performs sewing on a work to be sewn using a sewing-machine needle, while holding the work to be sewn in a state of being shaped in a predetermined shape on a plurality of seating portions arranged in a sewing direction; and a sewing method. When the seating portions are withdrawn from the work to be sewn so as to avoid interference between the sewing mechanism and the seating portions, a guiding mechanism enables movement in a first withdrawing direction for avoiding a first undercut portion of the work to be sewn, and movement in a second withdrawing direction for avoiding a second undercut portion of the work to be sewn.

Abstract: A sewing apparatus includes a driving source, a second driven shaft, and an eccentric member of an eccentric mechanism. The second driven shaft is connected to a drive shaft of the driving source and rotates. The eccentric member is connected to the second driven shaft. The eccentric member is capable of converting the rotational motion of the second driven shaft into the up and down motion of sewing machine needles. A cushion member is disposed between the eccentric member and the second driven shaft.

The movable plate can abut against a width-direction side surface of a workpiece. The holding pins are attached to the movable plate. The holding pins abut against an upper portion of the workpiece.

Abstract: A sewing mechanism is provided with: a post bed and sewing needles, wherein an article to be sewn is interposed between the post bed and the sewing needles. When the post bed comes closer to the article to be sewn than that in the previous sewing by at least a predetermined distance, in other words, when a separation distance between the article to be sewn and the post bed becomes less than that in the previous sewing by at least a predetermined distance, a thread pulling mechanism pulls threads hooked in needle holes of the sewing needles in a direction away from the post bed.

Abstract: This sewing needle holding device (10) is provided with: a holder (24) which holds the base end side of a sewing needle (14) provided with, from the leading end side toward the base end side in the extension direction, a small diameter portion (16), an outer diameter varying portion (20a), and a large diameter portion (18); and a presser member (26) which is mounted to the holder (24). The holder (24) causes at least the small diameter portion (16) and the outer diameter varying portion (20a) of the sewing needle (14) to protrude from a holder leading-end surface (34). The presser member (26) has a counter portion (46) that faces the holder leading-end surface (34). The counter portion (46) has formed therein an insertion hole (50) through which the small diameter portion (16) can be inserted. At least a part of the insertion hole (50) is provided with a pressure-receiving surface (52) that comes into abutment with the outer diameter varying portion (20a).

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.
