Embroidery frame support device

Abstract

In an embroidery sewing machine, an embroidery frame support device for supporting a front end portion of an embroidery frame installed in a cantilevered manner includes: a base member that is a base for attaching the embroidery frame support device to the embroidery sewing machine, and a Y slide rail (support member) having a movable end that can move relatively with the base member. The embroidery frame support device supports a front end portion of the embroidery frame from a lower surface thereof through an X slide rail attached to a tip portion of the Y slide rail. The embroidery frame support device can be attached to the embroidery sewing machine by screwing a base member to a cylinder bed. The screwing of the base member to the cylinder bed can be carried out from the upper side of a sewing machine table.

Description

[0001]This application is a U.S. National Phase Application of PCT International Application PCT / JP2006 / 310052 filed on May 19, 2006.TECHNICAL FIELD [0002]The present invention relates to an embroidery frame support device for supporting attachment of an embroidery frame that holds an embroidered object in an embroidery sewing machine, by which an embroidery operation can be carried out against a tubular embroidered object such as a T-shirt and a cap.BACKGROUND ART [0003]Heretofore, in an embroidery sewing machine, when an embroidery operation is carried out against a tubular embroidered object such as a T-shirt and a cap, the embroidery sewing machine is constructed so that an embroidery frame for supporting the embroidered object is supported in a cantilevered manner. For example, when the embroidery operation is carried out against a T-shirt, a sweat shirt or the like, the embroidery frame is supported by a holding arm that protrudes in a cantilevered manner from a frame drive el...

Benefits of technology

[0009]In view of the foregoing, it is an object of the present invention to provide an embroidery frame support device in which an attaching and releasing operation requires a little work and this makes it possible to heighten convenience thereof.

[0012]According to the present invention, the embroidery frame support device is constructed so that the base member is fixedly attached to the predetermined portion of the embroidery sewing machine, the support member is supported on the base member so as to be capable of moving relatively with the base member, and the free end of the embroidery frame is movably supported to the support member. Thus, it is possible to attach the embroidery frame support device to the embroidery sewing machine while the support member and the base member are integrated. In addition, it is possible to release the embroidery frame support device from the embroidery sewing machine. Since the support member and the base member are integrated, the present invention achieves a brilliant effect that it is possible to omit work of alignment when the embroidery frame support device is attached, and the attaching and releasing operation of the embroidery frame support device itself can be carried out easily. Further, in the case where the embroidery frame to be installed in the embroidery sewing machine is exchanged, the structure in which the free end of the embroidery frame is attached to the support member may merely be changed to one fitting the embroidery frame after exchange. Thus, it is possible to carry out an operation for changing a different type of embroidery frame easily without changing the attaching structure of the support member to the base member. Moreover, since the support member includes the Y slide mechanism constructed to be capable of expanding and contracting in the Y direction so as to follow the movement of the embroidery frame in the Y direction, it is possible to freely correspond to the embroidery frames having various sizes. Therefore, the present invention achieves a brilliant effect that it is possible to deal with the embroidery frame support device without seriously changing the configuration of the embroidery frame support device even in the case where a size and / or a type of the embroidery frame to be used are to be changed.

Problems solved by technology

This causes the front end portion of the embroidery frame to bend, and defect that a harmful influence is exerted on a sewing operation has occurred.

A removing operation of the embroidery frame support device is a complicated operation in which the support arm of the embroidery frame support device is released from the Y direction drive element and the linear guide of the support arm is released from the cylinder bed.

Further, in an attaching operation of the embroidery frame support device, it requires time to adjust alignment of attachment of the member (such as a support arm or a linear guide) and the like.

Namely, since such time is required for replacement of the embroidery frame when the embroidery frame is to be changed, operating efficiency is bad.

Thus, there has been an inconvenience that a plurality of support arms each having a different length are prepared in accordance with the sizes of bag frames and one support arm is to be changed in accordance with the size of the bag frame appropriately.
