Embodiment

[0028] Below, refer to Figure 1 to Figure 11 A first embodiment of the present invention will be described.

[0029] figure 1 The sewing machine of the present embodiment shown is a zigzag sewing machine M, which has a sewing machine head 1 and a foot column 2 erected on the right end of the sewing machine head 1, facing the sewing machine head 1 and extending from the foot column 2 upper end to the sewing machine head 1. Arm 3 extending to the left.

[0030] On the sewing machine head 1, a conveying tooth up-and-down mechanism (not shown) for moving the conveying teeth up and down and a conveying tooth front and rear actuating mechanism (not shown) for moving the conveying teeth forward and backward are provided. Winder and the thread wheel catcher (such as horizontal still) etc. that cooperate with sewing needle 6.

[0031] A scale plate opening 2 a is formed on a side surface of the leg portion 2 . Inside the opening 2a for the scale plate, there is a connecting portio...

Abstract

The present invention has a correction amount storage mechanism and a correction control mechanism; the correction amount storage mechanism stores the input correction amount, and the correction amount is used as an offset with respect to the origin position of the aforementioned actuator at the reference position of the stepping motor; the correction control mechanism corrects The control step corrects and controls the stepping motor so as to correct the displacement amount of the actuator according to the correction amount stored in the correction amount storage means.

Description

technical field [0001] The present invention relates to a control device for a driving mechanism, a control method using the driving mechanism, a sewing machine and a control method for the driving mechanism in the sewing machine, wherein the actuating body can be set at the origin position within the actuating range of the actuating body, and the actuating body The body is driven by a drive mechanism with a stepper motor. Background technique [0002] For example, in the past various electronically controlled sewing machines that can perform linear sewing or zigzag sewing, in order to drive the driving mechanisms such as the needle bar swing mechanism or the conveying mechanism, stepping motors are used, and each driving mechanism is set by the control device. The driving motor is controlled, so that the driving mechanism can be driven while sewing is controlled. [0003] However, stepper motors are usually controlled open-loop in a way that simplifies the control system. ...
