A holing sewing machine including a workpiece-presser elevating and lowering mechanism which elevates and lowers a workpiece presser, a needle-thread cutting mechanism which cuts a needle thread conveyed by a sewing needle; a bobbin-thread cutting mechanism which draws a bobbin thread from a bobbin and cuts the bobbin thread, an interlocking mechanism which mechanically interlocks the elevating and lowering mechanism, the needle-thread cutting mechanism, and the bobbin-thread cutting mechanism, with one another, such that the elevating and lowering mechanism elevates the workpiece presser after the needle-thread cutting mechanism cuts the needle thread and the bobbin-thread cutting mechanism cuts the bobbin thread, a drive source which drives the interlocking mechanism to operate the workpiece-presser elevating and lowering mechanism, the needle-thread cutting mechanism, and the bobbin-thread cutting mechanism, the drive source being controllable with respect to a speed of operation thereof to drive the interlocking mechanism, and a control device which controls the drive source such that the drive source is operated at a higher speed at at least one of a time when the needle-thread cutting mechanism cuts the needle thread and a time when the elevating and lowering mechanism elevates the workpiece presser, than a speed at a time when the bobbin-thread cutting mechanism draws the bobbin thread from the bobbin.

Holing sewing machine

Transferring system for transferring delivery members to their destinations through a computed transfer route when any trouble exists in a usual transfer route. The delivery members carrying a workpiece to be stitched, and is to be transferred to a desired work station (destination). The delivery member undergoes distribution by a plurality of distribution mechanisms and transferring rails connecting the distribution mechanisms. By suitable control to the distribution mechanism the delivery member reaches its destination even if any troubled location exists in a transfer route. The transferring system includes the distribution mechanism, line connecting information storage device, transfer control device, trouble storage device and new route setting mechanism. The trouble judgment device is connected to the line connecting information storage device. The transfer control device is connected to the line connecting information storage device and the new route setting mechanism. The new route setting mechanism is connected to the line connecting information storage device, the trouble judgment device and the trouble storage device.
