Abstract

A sewing machine is provided, which includes a table, support posts, upper and lower frames, a head unit, a bed unit, an X-axial head-unit-transport means and an X-axial bed-unit-transport means. An object is placed on the table. The support posts are provided on opposite sides of the table. The upper and lower frames connect the support posts to each other. The head unit is provided on the upper frame so as to be movable in an X-axis direction. The head unit has a head-unit-rotating means for rotating a sewing head. The bed unit is provided on the lower frame so as to be movable in the X-axis direction. The bed unit has a bed-unit-rotating means for rotating a sewing bed. The X-axial head-unit-transport means moves the head unit on the upper frame horizontally. The X-axial bed-unit-transport means moves the bed unit on the upper frame horizontally.

Description

technical field [0001] The present invention relates to a sewing machine and its drive control method. In order to achieve perfect sewing without adding stitches when sewing airbags, bags, shoes, etc., the sewing machine head is provided with a rotatable structure. A plurality of sewing machine heads are installed in a row on the upper side, thereby greatly improving the quality and productivity of sewing products. Background technique [0002] Generally speaking, airbags, bags, shoes and other products not only have thicker sewing materials, but also have more sewing threads that are difficult to sew in shapes such as circles, curves, and oblique lines. Existing sewing machines have more winding threads depending on the sewing direction. Hitch stitch, uneven stitch shape like this degrades product quality. [0003] figure 1 It is an example of a conventional sewing machine. A body (arm) unit 40 including a head unit is located on the upper side of the table 10, and a carr...
