Embodiment Construction

[0024] As shown in FIG. 1 , the buttonhole sewing machine is C-shaped, having a top arm 1 , a bottom base plate 2 in the form of a housing, and an approximately vertical bracket 3 connecting the top arm 1 and the bottom base plate 2 . The arm shaft 4 is generally supported in the arm 1; it can be driven by a motor 5, which is only schematically indicated in FIG. 8 . The actuation of the vertically movable needle bar 6 and the needle 7 as well as their jogging drive originate from the arm shaft 4 .

[0025] An x-y slide table 8 is arranged on the base plate 2, and the x-y slide table 8 is a cross slide, which can move in two horizontal coordinate directions, ie, in x and y directions. An x-y slide 8 of conventional design is known, for example, from DE 19807771 A1 (corresponding to US patent 6095066). The drive of the x-y slide 8 takes place via drives only roughly outlined in FIG. 8 , namely an x ​​drive 9 and a y drive 10 , which are electric position-controlled motors, pref...

Abstract

A buttonhole sewing machine comprises work piece clamps with displacement drives for displacement from an initial position of spread by a length of spread into a final position of spread. The work piece clamp comprises a supporting plate for accommodation of a work piece and a clamping plate mounted on the supporting plate. A clamping drive for actuation of the clamping plate supports itself on the supporting plate.

Description

technical field [0001] The invention relates to a buttonhole sewing machine comprising a needle drivable by an arm shaft; an x-y slide movable in the x direction by an x ​​drive and in the y direction by a y drive , and the x-y slide table supports first and second sewing material clamps, the first and second sewing material clamps are mounted to be movable relative to each other, and the x-y slide table includes a movement drive for making the sewing material clamps from the initial The deployed positions are moved relative to each other by a spread length to a final deployed position. Background technique [0002] JUKI MEB-3200 Instruction Manual Leaflet no. 02 29343316 discloses a common type of (lock) buttonhole sewing machine. It consists of an x-y slide that can be moved on the sewing plane by two stepper motors as x and y drives. Two sewing material clamps are arranged on the x-y slide for clamping the sewing material thereon. Via a pneumatic cylinder, they are mov...
