Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device which can easily embroider any figure using a handle embroidery sewing machine and can uniformly mass-produce the same figure.

In a conventional manual handle embroidery sewing machine, as shown in Figure 1, which shows the transmission mechanism in the direction of fabric feed, the direction in which the handle rotates and stops is controlled by several sets of bevel gears and a rotating shaft. ■It is transmitted to the shaft and stops in the direction indicated by the handle.

In the case of embroidery thread that does not use bobbin thread, use a needle with hook 0 [phase], and if the direction of the hook is not always facing the feeding direction of arrow ■, which is the direction of movement of fabric 0, the stitch will not be stitched. is not formed, and the direction of the hook of the needle [phase] must also be located in the direction P with respect to the direction P1 of the handle, which is the direction in which the fabric is fed.

Note that the winding mechanism (loop mechanism) is also naturally synchronized in the direction of hook 0. Therefore, the manual handle ■ is rotated and positioned in the required direction according to the pattern to determine the feeding direction of the fabric and create the desired pattern.This operation requires a high degree of skill and experience, and it is difficult to mass-produce the same pattern. is considered an extremely difficult task.

The purpose of this invention is to simplify the conventional complicated handle embroidery work and facilitate mass production of the same pattern.

An embodiment in which the present invention is implemented as a feeding direction regulating device will be described below based on drawings.

FIG. 2 shows an example in which a flat table according to the device of the present invention is attached to the P and T 0 of the main body 0 of a conventional Poshin using a coupling fitting.

The plane table @ has a frame @ that can slide left and right on a ruler O that moves vertically in parallel, and a recording board or a figure engraving board 0 is installed on one side of the frame @.
Attach the fabric @ to be embroidered to one side and attach it.
FIG. 2 is a plan view in which an arm 0 equipped with the main parts of the present invention such as a pointer [phase] and a pulley O is mounted on a support shaft [phase].

If you move the frame @ vertically and horizontally with the handle O, the movement locus figure of the recording plate [phase] at the position of the needle [phase] and the movement locus figure of the fabric @ at the position of the needle [phase] will be parallel. Form shapes with the same trajectory using the effect of a moving ruler. As shown in the third diagram, the device of the present invention has a pulley 01 chain wheel or a timing pulley [phase] attached to the pointer shaft 0 which has a built-in pointer [phase], and a chain wheel @ having the same number of teeth on the needle bar ■. Attach the shaft and connect the chain or timing belt [phase] so that the eccentric position direction (arrow ■) of the pulley [phase] with respect to the pointer shaft is the same as the direction of the hook ■ (arrow ◎) of the needle [phase]. has been done.

When the frame @ is moved with the handle O in the direction of the figure to be embroidered (in the direction of the arrow ■ in Figure 4), the pulley @ is positioned eccentrically with respect to the axis of the pointer [phase] and moves to the fourth position. As shown, hook 0 of needle 0 is located in direction P.

Next, if the frame [phase] is moved in the direction of the arrow [F] in Fig. 4 by changing the feeding direction of the fabric and moving the fabric @, the position of the pulley is eccentric from the pointer axis as described above, The angle rotates, and the amount of angle change is transmitted to the needle bar ■ shaft by the chain wheel [share] [phase] and the chain [phase], and the hook ◎ of the needle [phase] changes in the direction of the arrow Q and the fabric @. They will be facing each other in the direction of travel.

In other words, if frame 0 is moved according to the desired figure, the hook of needle 0 is
With the device of the present invention, the direction is always at a position opposite to the direction in which the fabric travels, and embroidery can be easily performed with normal stitches without the need for highly skilled operation of a conventional manual handle.

In addition, in the device of the present invention, when a writing instrument such as a pencil lead is inserted into the pointer shaft ■, the locus of the figure is written on the recording plate [phase], and the figure is engraved on the recording plate 0. It has the feature that uniform embroidery of the same figure can be easily mass-produced by pasting figure pattern 0 and tracing the pointer [phase] along the engraving groove.

In addition, a small motor [phase] is used so that the rotating load of the needle bar ■ on the sewing machine body does not directly affect the pulley O when the position changes due to the oppositeness of the needle shaft 0 and the pulley O at the eccentric position in the direction of movement of the fabric. An example in which the directional displacement of the needle bar (2) is made easier is shown in FIGS. 5 and 6.

In other words, a rotatable rocking contact [phase] having a pulley [phase] is provided on the arm q, and the chain wheel [Co., Ltd.] and the Wormhokiel [Co., Ltd.]
, the contact mounting plate [phase] is pivoted to the pointer shaft 0, and the swinging contact [phase] is attached to the pointer shaft 0.
If the wiring is made so that the motor 0 rotates forward and reverse when the contact point 0 and
phase] is displaced in the required direction, and the swinging contact [phase] moves in that direction. At that time, only a very small load on the directional displacement of the oscillating contact [phase] is affected by the rotational force that causes the displacement of the pulley, and the operation of the contact @, 0 causes the small motor to 0.
This is a device that operates in the required direction and changes the direction of the needle bar (2) of the sewing machine body, which requires a considerable rotational force through the chain wheel and chain [phase].

As explained above, the present invention enables even unskilled workers to easily perform embroidery operations, which required a high level of skill and experience with conventional manual needles, and to produce uniform patterns suitable for mass production. It has the effect of being able to create.
