Sewing machine

Abstract

The invention provided a sewing machine for improving the efficiency of sewing work and quickening it. The sewing machine is provided with a needle driving means 30, a cloth pressing means 40, a moving means 50 for positioning a sewing needle 11 to cloth, an input means 20 for inputting the setting relating to sewing, a storage means 103 for respectively storing sewing data and successive sewing data composed of two or more pieces of the sewing data, and an operation control means 100 for controlling respective parts on the basis of the respective stored sewing data. The order of sewing is specified for two or more pieces of sewing data and is inputted by the input means 20 and the storage means 103 stores it. The operation control means 100 makes the sewing of the sewing data or the successive sewing data be successively performed according to the stored order and waits for the detection of re-pressing by the cloth pressing means every time sewing is performed for the respective successive sewing data or sewing data for which the order is specified.

Description

technical field [0001] The present invention relates to a sewing machine which performs sewing in units of stored sewing patterns. Background technique [0002] A sewing machine such as a buttonhole sewing machine or a pattern sewing machine stores sewing data for each predetermined sewing pattern unit, and performs sewing according to the sewing data. [0003] As an example, a conventional buttonhole sewing machine has: a drive mechanism for moving the needle up and down, a presser mechanism with a frame-shaped presser for pressing the object to be sewn, and a moving mechanism for moving the needle and the presser relative to each other. Mechanism, an input mechanism for inputting relevant sewing settings, a storage mechanism for storing sewing data for determining sewing patterns, and an action control mechanism for controlling the actions of the needle drive mechanism and the moving mechanism according to the stored sewing data ( Refer to Patent Document 1).

AI Technical Summary

Problems solved by technology

Therefore, for example, as in polo shirts (polo shirts), the buttonholes of the first button (uppermost) are formed in a direction perpendicular to the buttonhole arrangement direction (up and down direction), and the second button below it From the buttonhole of the second button to the buttonhole of the fifth button on the conventional sewing machine, continuous sewing is set when the buttonhole is formed in the up and down direction to the fifth button. The buttonhole of the first button is continuous with the remaining buttonholes, and when the presser mechanism is raised and the presser is changed after the first buttonhole is formed, it is necessary to input new data for the next continuous sewing, etc. , there is a problem that the sewing operation cannot be sufficiently high-efficiency and rapid
