Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hat frame device for a multi-head embroidery sewing device, and more particularly, a multi-head embroidery sewing device is compact by narrowing the interval between adjacent embroidery sewing machines without reducing the sewable area of the cap. About what can be.

[0002]

2. Description of the Related Art Conventionally, a multi-head embroidery sewing device has a plurality of embroidery sewing machines arranged in a row and a front-back direction (Y direction).
Has a front-rear feed frame that is driven to move and a left-right feed frame that is driven to move in the left-right direction (X direction). Accordingly, a cloth holding frame having a substantially rectangular frame shape, a hat frame device for applying an embroidery pattern to the outer peripheral side portion of the hat, and the like are detachably attached.

In a general hat frame device, a base frame is provided near the cylinder bed of each embroidery sewing machine and is connected to a front-rear feed frame, and the hat frame is rotatably supported by the base frame and the hat frame is attached and detached. It is provided with an annular turning frame and a turning mechanism for converting the left-right movement of the left-right feed frame into turning of the turning frame via a wire.

In order to apply an embroidery pattern in a predetermined area on the outer peripheral side of the cap, the rotating mechanism rotates the rotating frame around a shaft parallel to the Y axis by a predetermined maximum rotation angle (for example, 270).
Rotate within °). The rotating mechanism includes a movable member connected to the left and right feed frames so as to be relatively movable in the left-right direction with respect to the base frame, and the wire wound around the rotating frame is attached to both ends of the movable member. Both ends are connected respectively. When the movable member moves relative to the left-right direction relative to the base frame in the left-right direction, the wire also moves in the left-right direction, and the rotating frame around which the wire is wound rotates relative to the base frame. .

Here, in order to rotate the rotating frame by the maximum rotation angle, in the two hat frame devices respectively corresponding to the two adjacent embroidery sewing machines, the rotating frames are spaced apart in the horizontal direction. It is necessary to make the maximum rotation angle larger than the maximum horizontal movement amount of the movable member (wire). Therefore, there has been a problem that the length of the multi-head embroidery sewing device in the left-right direction is inevitably increased.

In order to solve this problem, various hat frame devices have been proposed which can reduce the interval between adjacent embroidery sewing machines without reducing the sewable area of the hat. For example, in the hat frame device described in Japanese Patent Publication No. 3190515, two types of movable members having different shapes are provided for each of two adjacent hat frame devices, and a wire connected to an end of one movable member is used. The two movable members are arranged so as to be shifted in the front and rear direction so as not to interfere with the wire of the other adjacent movable member. In addition, JP 2000
In the hat frame device described in JP-A-212869,
An extension member that extends left and right is connected to the upper surface of the left end of the movable member in a leftward protruding shape, and on the lower side of the protruding extension member,
The right ends of the adjacent movable members are located, and the wires connected to the two adjacent movable members are arranged so as to be vertically displaced at the ends.

[0007]

However, in the hat frame device of the former publication, two types of movable members having different shapes are required, and the movable member itself shifts back and forth, which causes a shift in the front and rear. Therefore, other members connected to the movable member also need to have different shapes, which is disadvantageous in manufacturing cost.

On the other hand, in the hat frame device of the latter publication,
Since the extension member provided on the adjacent movable member is configured to cover the right end portion of the movable member from the upper side, when the plurality of hat frame devices are attached to the multi-head embroidery sewing device, the left end is not attached. It is necessary to install the hat frame device in order, and when replacing any one hat frame device,
There are restrictions on assembly and maintenance, such as when you have to remove other hat frame devices. Further, the number of parts increases as the extension member needs to be attached to the movable member, and the number of assembling steps of the hat frame device also increases, which is also disadvantageous in manufacturing cost. The purpose of the present invention is to
(EN) Provided is a cap frame device which simplifies a structure for reducing a space between adjacent embroidery sewing machines and is easy to install and remove.

On the other hand, the movable member of the rotating mechanism is connected to the left and right feed frames, and is relatively movable in the left and right direction with respect to the base frame. Since both ends of the wire wound around the rotating frame are connected to both ends of the movable member, when the left and right feed frame is driven to move left and right, the wire also moves left and right due to the movement in the left and right direction. Then, the rotating frame and the cap frame attached to the rotating frame rotate about an axis parallel to the Y axis within a predetermined maximum rotation angle. Thus, the embroidery pattern can be applied within a predetermined area on the outer peripheral portion of the cap attached to the cap frame by moving the cap frame back and forth and rotating it.

Here, a protrusion that protrudes a predetermined length toward the adjacent movable member is provided at the front end of either one of the left and right ends of the movable member, and the other end of the movable member has the protrusion of the adjacent movable member. A relief portion is provided to avoid interference with the protruding portion. That is, the movable member is displaced forward and backward at the end portion with the adjacent movable member, and the wire connected to the end portion is also overlapped forward and backward by a predetermined length. Therefore, the wire corresponding to the maximum rotation angle of the rotating frame is moved. It is possible to reduce the distance between the two rotating frames adjacent to each other by the predetermined length while ensuring the maximum amount of movement in the left-right direction.

Here, the above effect can be realized by simply forming the projecting portion and the relief portion at one end and the other end of the movable member, the structure thereof is simplified, and it is compatible with a plurality of embroidery sewing machines. It is also possible to configure a plurality of movable members having the same shape. Further, since the protruding portion is located on the same plane as the adjacent movable member, the movable member may vertically interfere with the adjacent movable member during the work of mounting or removing one cap frame device.
