Description

[Detailed Description of the Invention] The present invention relates to a guide bar drive device for a Jacquard warp knitting machine.

In a guide bar drive device for a conventional jacquard warp knitting machine, as shown in FIG. A dropper bar 3 is provided in parallel with the dropper bar 2, and a dropper 4 slidably provided in the dropper bar 3 is dropped between the planchin guides 1 and 1, and the dropper bar 3 is further displaced in the direction of the arrow. Accordingly, the plantine guide 1 is bent by the dropper 4, and the position of action with respect to the needle 5 is selected.The jacquard bar 2 and the dropper bar 3 are driven by a handle such as a pattern wheel 6 provided on one longitudinal side. This is done via a bushing rod 7 from an ejecting device, and is pressed by a tension spring 8.

However, if each dropper acts on the flanchin at the same time during knitting, or if the knitting width is as wide as 170 inches or more and a large number of droppers act on the flanchin, the force with which the planchin guide is bent by the dropper is the return force of the tension spring. In this case, unnecessary displacement is applied to the Franchin bar by the dropper bar, and as a result, the Franchin guide cannot be displaced to the normal position.

For this reason, conditions have been added to the operating state of the dropper, and pattern creation using jacquard has had to be restricted.

Therefore, as a solution to the above-mentioned drawbacks, JP-A-50-
105958, and in this proposal, a jacquard bar and a dropper bar are linked with one lever, and the lever has a point of action on the dropper bar at the center position, and a fulcrum is provided on the line of action of the jacquard bar. , the other end is brought into contact with a bushing rod from a handle device to the dropper bar.

However, in this proposal, the amount of displacement of the dropper bar in the handle setting device needs to be at least twice the actual displacement position, which increases the displacement of the bushing rod and causes impact noise as the rotation speed increases. If the device is a handle drum for pattern chain links, special cutting is required, which is troublesome in processing and leads to increased costs.Also, the dropper bar must be in a stationary state when the dropper is applied. There was no firm guarantee that there would be any.

This invention was made to eliminate the above-mentioned drawbacks.
To provide a guide bar drive device capable of keeping a jacquard parr stationary no matter what force is applied when a dropper acts on a flanchin guide.

Next, the present invention will be explained based on the embodiment drawings. Fig. 2 is a perspective view showing an embodiment of the guide bar driving device of the present invention, and Fig. 3 similarly shows only the related parts of the jacquard bar. FIG. 2 is a plan view showing that the jacquard parser 2 is provided with a lever 9 as a deflecting means that acts in the opposite direction to the displacement in the direction of arrow A due to the action of the pattern wheel 6 on the dropper bar 3; It has a fulcrum 10 in the center of its length, and one end has a pattern wheel 6.
The handle is connected to the handle a and the bushing rod 7a, and the other end is rotatably connected to a connecting rod 12 connected to the jacquard spar 2 by a pin 11.

As shown in FIG. 4, a pin 14 is engaged with the notch 13 at the end of the connecting rod 12, and an indentation 15 corresponding to the pin 14 provided at the other end of the lever 9 is engaged with the pin 14. It is designed to match.

Therefore, when installing the jacquard parser 2, it is sufficient to fit the connecting rod 12 into the tip of the lever 9 and fit the indented part 15 into the pin 14, and then apply the tension spring 16, or remove it. The operation will be easier if you perform the reverse operation.

Since the present invention is constructed as described above, even if the dropper 4 falls between the plantain guides 1 and the dropper bar 3 is subsequently displaced in the direction of arrow A and bends the plantain guide 1, the jacquard par The force that attempts to move the jacquard bar 2 acts in the direction of pressing it against the pattern wheel 6 through the connecting rod 12, lever 9, and bushing rod 7a, so the jacquard bar 2 itself does not undergo any unnecessary displacement, and as a result, the flange Many droppers 4 at once on chin guide 1
Even if the flange guide 1 acts, the flanch guide 1 is bent normally and a predetermined displacement is obtained, so that the operating position with respect to the needle is selected correctly.

Therefore, according to the present invention, there is no restriction on the number of droppers that act on the flanchin guide in a jacquard warp knitting machine, so the range of patterning of jacquard can be expanded.
