A sewing system includes: a robot manipulator; a plurality of assemblies attached to and detached from the robot manipulator and each configured to perform predetermined work on cloth; a server stores process data indicating a relationship between a plurality of processes for manufacturing a sewn product from the cloth and the assembly used in each of the plurality of processes; and a control device configured to select an assembly to be mounted to the robot manipulator based on the process data.

Sewing system

The disclosure improves the quality of seams in sewing using a sewing machine, and includes: a holder holding fabric; a driver being detachable from a bed of a sewing machine and driving the holder along an upper surface of the bed; a position detector detecting a position of a sewing needle of the sewing machine in an up-down direction; and a controller controlling driving of the holder, which is performed by the driver, based on a detection result of the position detector.

Sewing machine external unit

A creasing apparatus includes a top plate having an upper surface supporting a fabric, a robot manipulator, a folding assembly mounted on the robot manipulator and configured to make a crease on the fabric by pinching the fabric from above, and a control device configured to control the robot manipulator and the folding assembly.

Creasing apparatus

A sewing system which includes a detector for detecting an edge of a cloth installed on an installation table, a cloth conveyor for conveying the cloth from the installation table to a sewing machine, and a controller, wherein the cloth conveyor includes a holding member that holds the cloth, and the controller includes a holding position decision portion that determines a holding position of the cloth based on detection data of the detector, and a conveyance control portion that controls the cloth conveyor such that the holding member holds the holding position. In the sewing system according to the above, it is possible to prevent deterioration in productivity of sewn products.

A lower thread supply device of a sewing machine includes a bobbin, a bobbin case, a magnetic force member, and a magnetic force change portion. The bobbin has a cylindrical portion for inserting into a spindle of a shuttle, a shuttle side flange portion, and a front surface side flange portion which is magnetic, and a lower thread is wound around an outer circumference of the cylindrical portion between the shuttle side flange portion and the front surface side flange portion. The bobbin case has a non-magnetic cover portion having a front surface side part and a side wall part, housing the bobbin and transmitting a magnetic force. The magnetic force member is arranged at the front surface side of the bobbin case and attracts the front surface side flange portion of the bobbin by a magnetic force via the bobbin case.
