Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hat frame device, and more particularly to a cap frame device that can be easily attached to an embroidery sewing device without using a tool.
[0002]
[Prior art]
An embroidery sewing apparatus that applies various embroidery patterns to a workpiece is generally provided with a front-rear feed frame for feeding the workpiece in the front-rear direction and a left-right feed frame for feeding in the left-right direction. Is attached with a hat frame device for applying various embroidery patterns to the outer surface of the hat.
A general hat frame device includes a main body frame, a rotating frame that is rotatably supported by the main body frame, and a rotation mechanism that converts the movement of the left and right feed frames in the left-right direction into rotation of the rotating frame. And a clamp mechanism for detachably connecting the main body frame to the front and rear feed frame.
[0003]
As the clamp mechanism, those having various configurations have already been proposed. For example, the applicant of the present application has proposed the following clamp mechanism for a hat frame device (see Japanese Patent No. 2958947).
This clamp mechanism has a connecting plate fixed to the main body frame, a clamp rod supported by the connecting plate so as to be movable up and down, and a connected state in which the main body frame is connected to the front and rear feed frames connected to the lower end of the clamp rod. And a switching lever for switching over the connection release state. The clamp rod includes a flange portion at the upper end portion and a shaft portion extending downward from the flange portion. On the other hand, the front / rear feed frame has an insertion hole through which the flange of the clamp rod can pass up and down, and a long hole that extends from the insertion hole to the left and allows the shaft of the clamp rod to move relative to the left and right. Is formed.
[0004]
When attaching the cap frame device to the front / rear feed frame, position the connecting plate below the front / rear feed frame, pass the collar through the insertion hole from below, and then move the entire cap frame device to the left. By moving the connecting plate, clamp rod, and switching lever to the left relative to the front / rear feed frame to engage the shaft part with the elongated hole part, the main body frame is switched to the connected state by the switching lever. The main body frame is connected to the front / rear feed frame. According to this clamp mechanism, the main body frame can be connected to the front-rear feed frame without using a tool.
[0005]
[Problems to be solved by the invention]
However, in the hat frame device of the above publication, when engaging the shaft portion of the clamp rod with the elongated hole portion of the front and rear feed frame, the hat frame device itself having a considerable size and weight must be moved to the left. In addition, it takes time and effort to install.
An object of the present invention is to improve the operability of the clamp mechanism and facilitate the work of attaching the cap frame device.
[0006]
[Means for Solving the Problems]
The cap frame device according to claim 1 includes a main body frame, a rotating frame rotatably supported by the main body frame, and a clamp mechanism for connecting the main body frame to the front and rear feed frames of the embroidery sewing apparatus. In the frame device, the clamp mechanism includes a connecting plate fixed to the main body frame, a clamp rod that is supported by the connecting plate so as to be movable up and down, and has a flange portion at an upper end portion and a shaft portion extending downward from the flange portion. And a switching lever that is connected to the lower end of the clamp rod to switch between a connected state in which the main body frame is connected to the front / rear feed frame and a disconnected state, and a flange of the clamp rod is formed in the front / rear feed frame so that it can pass through And a long hole portion extending continuously from the insertion hole and allowing relative movement of the shaft portion of the clamp rod with respect to the front and rear feed frame. Parts are characterized in the provision of the engaging hole that penetrates relatively movable along the elongated hole.
[0007]
The embroidery sewing apparatus is provided with a front / rear feed frame for sending a workpiece in the front / rear direction and a left / right feed frame for sending the left / right direction. On the other hand, the main body frame of the hat frame device is connected to the front / rear feed frame by a clamp mechanism in the vicinity of the cylinder bed of the embroidery sewing device, and the rotating frame supported rotatably on the main body frame is used to attach the hat. A cap frame is installed. The hat frame device is also provided with a rotation mechanism that converts the movement of the left and right feed frames in the left-right direction into rotation of the rotation frame. When applying the embroidery pattern on the outer surface of the cap, if the front and rear feed frame is moved and driven in the front and rear direction, the main body frame and the rotating frame move in the front and rear direction integrally with the front and rear feed frame, and the left and right feed frame in the left and right direction When driven to move, the rotation frame rotates a predetermined angle via the rotation mechanism.
[0008]
In the clamp mechanism, the clamp rod is supported by the connecting plate so as to move up and down in a state where the shaft portion of the clamp rod penetrates the engaging hole of the connecting plate so as to be movable relative to the connecting plate. Therefore, when the main body frame is connected to the front / rear feed frame by the clamp mechanism, when the clamp rod is inserted through the insertion hole, the oblong hole of the front / rear feed frame and the engagement hole of the connecting plate The clamp rod is movable relative to the front and rear feed frame and the connecting plate. That is, only the clamp rod and the switching lever are integrally moved relative to the front / rear feed frame and the connecting plate along the elongated hole portion, and then the main body frame can be switched to the connected state by the switching lever. Since it is not necessary to move the whole with respect to the front-rear feed frame, the operability of the clamping mechanism is excellent.
[0009]
Here, with the shaft portion of the clamp rod inserted into the engagement hole of the connecting plate, the clamp rod is inserted into the insertion hole, and the clamp rod and the switching lever are integrated with the front and rear feed frame and the connecting plate. Alternatively, the main body frame may be connected to the front / rear feed frame by switching the main body frame to the connected state by the switching lever after the relative movement to the long hole portion side (Claim 2). In this case as well, as in the first aspect of the invention, only the clamp rod and the switching lever need to be integrally moved relative to the front and rear feed frame and the connecting plate along the elongated hole portion. Because it does not need to be moved left and right, the operability of the clamp mechanism is excellent.
[0010]
A cap frame device according to a third aspect of the present invention is the cam mechanism according to the first or second aspect, wherein the switching lever presses the connecting plate toward the front-rear feed frame side in order to switch the main body frame to the connected state via the clamp rod. It is characterized by comprising. Therefore, when the switching lever is operated to the connected state side, the connecting plate is pressed toward the front / rear feed frame by the cam mechanism, and the connecting plate and the front / rear feed frame are connected.
[0011]
According to a fourth aspect of the present invention, in the invention of any one of the first to third aspects, the cap frame device engages a pin hole formed in the front-rear feed frame on the connection plate and positions the connection plate relative to the front-rear feed frame. A positioning pin is provided. Therefore, when the clamp rod is inserted into the insertion hole of the front / rear feed frame, the connecting plate does not rotate relative to the front / rear feed frame by engaging the positioning pin with the pin hole. Can be done.
[0012]
