Embodiment Construction

[0037] DETAILED DESCRIPTION OF THE INVENTION The present invention will be described in detail below with reference to the accompanying drawings showing preferred embodiments.

[0038] Such as figure 1 , figure 2 As shown, the button sewing machine 1 includes a base 1a, a column 1b and a machine arm 1c. The base 1a has a cylindrical front end extending forward. The upright column 1b is provided in an upright configuration at the rear of the base 1a. The upper part of the column 1b supports the base end part of the machine arm 1c. The arm 1c extends forward in parallel with the base 1a.

[0039]The button sewing machine 1 includes a needle bar 10 and a sewing needle 11 . The needle bar 10 is supported vertically at the front end of the arm 1c. The sewing needle 11 is attached to the lower end of the needle bar 1c protruding downward of the machine arm 1c. The needle bar 10 and the sewing needle 11 are raised and lowered by the operation of a needle bar driving mechanism...

Abstract

PROBLEM TO BE SOLVED: To provide a button sewing machine capable of describing basic movement amount data on the basis of button sewing needle location point data, with hole-to-hole movement data showing buttonhole spacing, button hole inner needle location point data with a reference point in the button hole as the origin, and needle location order data. ŽSOLUTION: The basic movement amount data shown in Fig.6 includes main movement amount data and correction movement amount data. In the Fig.6, data order shows the sequence of data, and movement content shows movement from the origin to a needle location point 1, and movement between needle location points from the needle location point 1 onward. The main movement amount data shows X-direction movement and Y-direction movement in a coordinate system. The correction movement amount data shows x-direction coordinate data and y-direction coordinate data with the reference point in the buttonhole as the origin. When the needle location point moves within the buttonhole, the main movement amount data is (0, 0). Ž

Description

technical field [0001] The invention relates to a button sewing machine and a button sewing method implemented by the button sewing machine. Background technique [0002] No. 2005-287543, Japanese Laid-Open Patent Publication, Heisei 10 (1998) No. 137466 and other record button sewing machines are used when sewing buttons to cloth. The button sewing machine includes: a sewing needle disposed on the upper part of the base, a shuttle disposed on the lower part of the base, and a holding member for holding buttons and cloth on the base. [0003] The needles are driven up and down by the needle bar driving mechanism arranged inside the machine arm. The shuttle swings back and forth synchronously with the raising and lowering of the sewing needle by the drive of the shuttle driving mechanism provided inside the base. The holding member moves in the X direction (left-right direction) by driving the X-axis motor, and moves in the Y-direction (front-rear direction) by driving the ...
