Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to an embroidery sewing machine, and in particular, to an embroidery sewing machine.
In addition to directional control, it enables amplitude movement in two directions for the secondary rod,
It concerns an embroidery machine that can embroider at high speed.

(Prior art) Conventionally, the embroidery machine is driven by a stock drive mechanism in a direction parallel to the cloth feed direction (Y-)' direction and in a direction perpendicular to the 71i feed direction (X-X direction). However, the weight of the embroidery frame itself increases the movement ``F'', which makes it impossible to increase the speed of the sewing machine, resulting in a disadvantage of poor production efficiency.

(Objective and Solution) The present invention has been made to eliminate the drawbacks of the prior art described above, and its purpose is to support a straight bar that slidably supports a side bar. By making the 4P part of the body into a ball bearing, the copper rod will not sweat.

There is a J, which can be swung in the direction of , and this allows for two-way control of the C embroidery frame. Another object of the present invention is to expand the scope of use of embroidery sewing machines.Also, by using a drive mechanism to drive the multiple sticks in any direction, there is no need to move the embroidery frame in any direction. By reducing the size of the kinematic skewer and increasing the speed of the sewing machine, production capacity was increased.

is almost equal to the distance fit F between the axis of the first pivot 25 and the axis of the sixth pivot 43, and the original surface of the thread ring catching portion 51a of the ball axis center line member 51 of the ball bearing 19 The distance G is the distance between the axis of the first pivot 25 and the axis of the second pivot 29! 1t! l G , and the needle bar 4 is moved in the direction of the arrow When moving in the X direction or the Y-Y direction, the $1 plate 8 and the strip member 51 are moved to the temporary hook drive mechanism 9 and the hook sliding mechanism 1'1:
C1 and Ij are configured to move synchronously in the same direction.

(Operations and Effects) The present invention is constructed as described above, and its operations will be explained below. When the main shaft 2 rotates in the direction of the arrow 1, the balance cranks 1 and 5, the crank bin 16,
Via the i1 bar crank 20 and the sword bar shore 21! The first rod 4 moves 1n in the vertical direction within the bearing portions 3 a and 3 b of the needle bar support 3 . At 1b1, the strip member 51 is rotated by the lid mechanism 10 in the same direction as the main shaft 2, and the needle 40 and the strip member 51 are rotated by the lid mechanism 10.
A thread loop (U in the figure) is formed by the cooperative operation of the thread loop catcher 518 and the thread take-up 17, etc., and a stitch is formed in the cloth (not shown) stretched on the embroidery frame. At this time, the embroidery machine is driven by a known drive m4M in the direction of arrow YY or in the direction of arrow XX perpendicular to the direction of arrow YY.

When the first stepping motor 27 is rotated by the micro=I pinion L and the first stepping motor 27 is rotated by the micro=I pinion L, the -C oscillation 1
The first rod 5 swings about the first pivot 25 in the direction of arrow 13-B. In other words, the first connection 1-] Rad28,
The second connecting rod 41 and the third connecting rod [1
: Then, the side rod support 3, the sub-plate 8, and the strip parts Δ51 largely move in the direction of arrow x-X, and the hook/IO and thread ring catcher 5
For cooperation with 1a, arrow X- is shown in Figure 3.
A stitch of distance IX is constructed in the X direction. At this time, distance F and 131, distance 1ii11 F and [1, distance G and G,
Since the swing angles of the male mouth support 3 and the first output rod 5 are set substantially equal, the hook 40, sub-plate 8, and strip member 51 move synchronously. ,
The seams are formed reliably.

The second stepping motor 36 is connected to the microcombi-2-
In the evening J, turn μru □ and gonion 38, rack 3
5a and the second drive rod 35, the needle bar support 3 swings in the direction of arrow C-C, and the button 40 and the thread ring catcher 51a
As shown in FIG. 4, the distance 1 in the direction of arrow Y=Y is achieved by the cooperation with III Y, the stitches are constructed. At this time, since the needle bar support 3 is pivotally mounted by the ball ll1lh receiver 19, it can swing smoothly. In addition, as shown in Fig. 5, if the first and second stepper operators - 27.36 and 27.36 are placed on the computer and adjusted as appropriate and rotated, the result will be as shown in Fig. 5. arrow x
A synthetic stitch with a distance of X2 at jJltll of -X and a distance of 1ilIfY2 in the direction of arrow YY is constructed.

In this way, the first and second stepping data 27.
By rotating 36, the 11-bar support 3 smoothly swings around the ball bearing 19, allowing stitches to be formed in various directions.

As the embroidery frame moves in the directions of arrows X--X and Y--Y, the rod 21 swings in an arbitrary direction, which has the effect of allowing advanced embroidery to be performed. In addition, since the needle bar is driven in any direction by the first and second needle bar drive mechanisms, there is no need to move the embroidery frame during this drive, and as a result, the moving mass is reduced. By increasing the speed of the sewing machine (b), the effect of improving efficiency will be noticeable.
