Embodiment Construction

[0032] (Overall structure of the sewing machine of this embodiment)

[0033] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0034] exist figure 1In the sewing machine 1 according to the present embodiment, the timing of the vertical movement of the needle bar 11 and the timing of the moving mechanism 20 moving the sewing product are controlled according to the sewing data 51 to form stitches. In the following description, the X-axis direction and the Y-axis direction perpendicular to each other are provided along a horizontal plane perpendicular to the vertical movement direction of the needle bar 11, and the plane is referred to as an X-Y plane.

[0035] The sewing machine 1 has: a sewing machine frame 2; a needle bar 11, which holds a sewing needle 12 and moves up and down; a moving mechanism 20, which holds a sewing object, and performs a feeding operation to move it along an X-Y plane; an operation panel 30,...

Abstract

The present invention relates to a sewing machine capable of finding out needle location having generated positional error. The sewing machine has a main shaft driven through the rotating of a sewing machine motor, a needle bar which is linked with the main shaft and moves up and down, a travel mechanism which makes a lower board and a cloth pressing foot move, a control part which controls the actions of the sewing machine motor and the travel mechanism on the basis of sewing data, an EEPROM which stories sewing data and deviation detecting threshold value, a CPU aiming at each needle location for detecting error between a needle location position and an actual needle location position on the basis of sewing data and for determining whether the error is bigger than or equal to the deviation detecting threshold value or not, when the deviation is larger than or equal to the deviation detecting threshold value, it is represented that the information of the needle location generating the error is storied in the EEPROM, and an error display control unit capable of displaying the needle location generating the error and other needle locations on a display unit in a recognition mode.

Description

technical field [0001] The present invention relates to a sewing machine which automatically performs cloth feeding and needle drop according to a preset stitch formation position pattern. Background technique [0002] Currently, the above-mentioned sewing machine has: a moving mechanism that moves a sewn product such as cloth in two directions along a plane substantially perpendicular to the vertical movement direction of the needle bar; According to the sewing data of the needle drop position of the stitch, control the driving of the sewing machine motor and the moving mechanism, the control part controls the timing of the needle bar moving up and down and the timing of the moving mechanism moving the sewing object according to the sewing data, so as to form a stitch . [0003] When performing a sewing operation using the above-mentioned sewing machine, the needle drop position may deviate from a preset position, resulting in a positional error. Causes of the position er...
