Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hat frame driving device in an embroidery machine for embroidering the front surface of a cap (mainly a cap) on which sewing has been completed.

[0002]

2. Description of the Related Art A hat frame driving device of this type is disclosed in, for example, Japanese Patent Publication No. 1-53384. As is clear from this publication, the frame support on which the hat frame is mounted is rotatable with respect to the Y-axis driving body of the embroidery machine, which is the driving direction, and the Y-axis driving body. It is mounted to move with. The frame support and the X-axis drive of the embroidery machine are connected by an interlocking rod and a link member. Therefore, the frame support body rotates around the above-mentioned axis in conjunction with the driving of the X-axis drive body in the X direction and moves in the Y direction integrally with the Y-axis drive body. By the way, although the Y-axis drive body is integrally connected to the drive unit, the X-axis drive body is integrally moved in the X direction with respect to the drive unit, and is relatively movable in the Y direction. Is bound to. Thereby, the movement in the Y direction of the frame support acting on the X-axis drive body is released through the interlocking rod and the link member.

[0003]

The coupling between the X-axis drive body and its drive portion is performed by moving the guide groove of the X-axis drive body in the Y direction with respect to the roller provided on the drive belt of the drive portion. It is configured to be engaged as much as possible. So this X
When the shaft driving body moves relatively in the Y direction with respect to the driving portion, the X-axis driving body is biased with respect to the rollers of the driving belt. Further, as a matter of course, there is an unavoidable gap between the roller of the drive belt and the guide groove of the X-axis drive body. For these reasons, the drive transmission in the X direction of the X-axis drive member to the frame support member becomes unstable, which in turn adversely affects the finish of the embroidery. The technical problem of the present invention is that the X-axis drive body is relatively biased with respect to the X-axis drive unit regardless of the Y-direction movement of the Y-axis drive body including the frame support to which the hat frame is attached. By avoiding the movement, the driving force in the X direction transmitted to the frame support body by the X-axis drive body is stabilized.

[0004]

In order to solve the above-mentioned problems, the hat frame driving device in the embroidery machine of the present invention is constructed as follows. That is, the embroidery machine includes an X-axis driving body and a Y-axis driving body that are individually driven in the X and Y directions orthogonal to each other by the X-axis driving section and the Y-axis driving section. With respect to the Y-axis drive body, it is rotatable about an axis in the Y direction, which is the drive direction, and
A hat frame drive device in an embroidery machine which is provided so as to move together with an axial drive body, and in which the frame support body is driven around the axis line in response to the drive of the X axis drive body in the X direction. The X-axis drive unit is integrally connected to the X-axis drive unit, and the X-axis drive unit has an interlocking base for transmitting the drive to the frame support in the X direction. Are coupled so as to move integrally and relatively in the Y direction.

[0005]

According to this structure, the X-axis drive unit is integrally coupled to the X-axis drive unit, and the movement of the frame support body in the Y direction due to the drive of the Y-axis drive unit is controlled by the X-axis drive unit. It is released by the relative movement of the interlocking base with respect to the driving body. Therefore, it is possible to prevent the X-axis drive body from being biased with respect to the X-axis drive section, and to stabilize the drive transmission in the X direction to the frame support body by the X-axis drive body. The rotation is properly controlled.
