no. 1 Embodiment

[0054] The control box 20 of this embodiment is composed of a frame 21 as a main frame on which several electrical components are installed; a first cover 30 covering the outside, a second cover 31 and a third cover 32, and mounting accessories 22 and 23 as mounting components. .

[0055] The frame 21 is made of metal, such as integrally formed with aluminum die-casting parts, and made as figure 2 The section shown is T-shaped, and consists of a plate-shaped main frame part (frame member) 21B extending in the vertical direction, an upper frame part 21A and a lower frame part 21C arranged horizontally above and below the main frame part 21B, etc. constitute. The upper frame part 21A is not only used as a reinforcing member because of the high bending stress of the main frame part 21B, but also serves as a base frame for installing the control box 20 at the installation position, and forms an installation fitting for fixing the control box 20 for installation. 22, 23 screw ho...

no. 2 Embodiment

[0082] Figure 8 The sewing machine control box 200 of the second embodiment is shown.

[0083] In the control box 200 of this embodiment, the frame portion 153 and the lower cover portion 150 are integrally formed, and other configurations are basically the same as those of the first embodiment.

[0084] The frame body 152 is made into a Y-shaped section structure, and the upper end 150D of the lower cover portion 150 of the upper structure hangs around the sewing machine installation hole 102A of the sewing machine table 102 to support it. Furthermore, there is provided a frame portion 153 hanging downward from the center portion in the front-rear direction of the lower end surface (constituting the upper frame portion) 150B of the lower cover portion 150 .

[0085] The first cover 160 covering the rear of the frame portion 153, the second cover 161 covering the front and upper side of the frame portion 153, and the third cover 162 covering the front of the frame portion 15...

Abstract

The object of the present invention is to provide a control box of a sewing machine in which, by changing an arrangement of a frame of the control box, a size in X-Y direction of the control box can be compact, the cooling efficiency of heating parts can be increased, a deviated load which is caused by pedaling and loaded on the frame of the control box is eliminated, and further, it can be easily installed. The control box of the present invention is a control box of the sewing machine which is located under the table of the sewing machine, and in which control parts for use in the control of the sewing machine are accommodated. The control box is such structured that it has a vertically extending plate-like frame member, and on both sides of the frame member, the electric parts are fitted.

Description

[0001] The present invention is a divisional application of the patent application submitted on June 12, 1999 with the application number "99109716.5" and the title of invention "control box for sewing machine". technical field [0002] The invention relates to a sewing machine control box arranged under the sewing machine table in the technical field of industrial sewing machines for accommodating electrical components used for sewing machine control. Background technique [0003] On an industrial sewing machine, a sewing machine motor for driving the sewing machine is provided under the sewing machine table, and a control box is installed on the lower side thereof. [0004] also, Figure 10 and Figure 11 An industrial sewing machine is shown in which the sewing machine motor is installed on the head side of the sewing machine as the size of the sewing machine motor is reduced. Among them, P17 represents the sewing machine head, P18 represents the sewing machine motor, P1...
