Embodiment Construction

[0025] A sewing machine embodying an embodiment of the present invention and a control method thereof will now be described with reference to the accompanying drawings. First, FIGS. 1 and 2 are plan views showing a multi-head embroidery sewing machine 1 using the control method of the present invention. This embroidery sewing machine 1 has: a pair of left and right pillars 2 erected on the table, and a lower frame (not shown) and an upper frame 3 respectively extending to the left and right directions supported between the lower parts and the upper parts of the two pillars 2. frame, the aforementioned lower frame supports the table top 4 slightly horizontally. A planar, horizontally long rectangular frame-shaped sewing frame 5 is placed on the table 4 , and the short sides of the left and right sides of the sewing frame 5 are connected with respective driving bodies 6 . Like this, when the X-direction drive mechanism 7a of the frame drive mechanism 7 that is provided with fro...

Abstract

The invention provides a sewing machine and its control method which reduces troubles by shortening the time required for recovering yarn breakage. This control method for a sewing machine controls the sewing machine in which the end part of a table for placing a sewing frame is provide with a recessed part allowing a worker to enter. The control method comprises steps (step S101, S103) of retreating the sewing frame from the upper side of the recessed part when the sewing frame is positioned on the upper side of the recessed part at the time of detecting yarn breakage to stop the drive of the sewing frame. The sewing machine has a plurality of sewing machine heads, and comprises a step (step S102) of cutting a yarn by the sewing machine head having not yarn breakage before the retreating step, and a step (step S106) of returning the sewing frame to the position before retreating in restarting embroidery processing from the state of stopping the embroidery process through the retreating step.

Description

technical field [0001] The present invention relates to a sewing machine and its control method. The sewing machine is provided with an operator-accessible recess at the end of the table top on which a sewing frame is loaded. In addition, it is customary to call the left-right direction X direction (or V direction) and the front-back direction Y direction (or H direction) in sewing machines, and this description is also used in this description. Background technique [0002] In a multi-head sewing machine with a large table depth (Y direction) equipped with a sewing frame, since there is a distance from the end of the table to the sewing head, the sewing head performs maintenance work such as thread replacement or thread breakage. Difficulties will arise. Therefore, like the sewing machine 50 shown in FIG. 5 , in order to allow the operator H to approach the sewing head 51 during operation, a recess 53 into which the operator H can enter is provided at the front end of the ...
