Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for punching a Jacquard card for use in a Jacquard shell machine.

The pattern creation mechanism using the Jacquard Draciel machine is
As shown in FIG. 1, a dropper 2, whose vertical movement is selected via a jacquard device provided above, is attached to a flanchin guide 1 that holds an elastic thread guiding rod. By the relative sliding in the direction of the needle row by a flanking guide bar 3 which is provided between the guides 1 and has the flanking guides 1 attached in parallel, and a dropper bar 4 which has the droppers 2 vertically arranged in a slidable manner. , the flange guide 1 is bent by the dropper 2,
This is done by changing the action position of the pattern thread threaded through the flanchin guide 1 with respect to the needle.

Conventionally, the following method has been used to control the dropper 2.

This is a method in which the dropper 2 in the operating position is dropped when it is necessary to bend the flanchin guide through which the pattern thread is threaded.

However, in the above method, in order to once pull up the entire dropper 2, the bottom plate 7 engaged with the vertical needles 6 connected to the dropper 2 through the thread 5 moves up and down in the direction of the arrow. Since the entire force required to pull up the dropper 2 is applied each time, mechanical strain is caused, which prevents the knitting rotation from increasing.

However, some jiacard devices used in looms are equipped with a knife frame that allows the warp needles to be freely attached to and detached from the knife frame and to pull up only the healds connected to the warp threads that perform shedding. Compared to the above-described device, the device requires fewer droppers to be pulled up for each course, so the overall burden can be reduced.

The present inventor has developed and researched a method for punching Jacquard cards in order to apply this method to a dropper puncher machine.

In the jacquard dropper machine shown in Fig. 1, which pulls up only the inactive dropper 2, the bottom plate 7 is fixed and the knife frame 8 moves up and down in the direction of the arrow.
When the horizontal needle 9 is lifted by the non-punching device of the Jacquard card 10 and moved to the position of the selection needle 11', the vertical needle 6 is pressed by the convex portion of the presser 23 and moved to the position indicated by the dotted line. As a result, the vertical needle 6 disengages from the knife frame 8 and falls downward, causing the dropper 2 to fall between the flanking guides 1 via the thread 5, and the dropper 2 falls onto the feed ratchet wheel 24. Therefore, the Jacquard card 10 is moved in the direction of the arrow for each card, and in this way, the dropper 2 is pulled up only when it is not in the working position, so the working position of the dropper is always between the same flanch guides. It will be limited.

On the other hand, the patterning method for jacquard lace is determined by the density of the pattern yarn 12 that fills the wale made up of stitch yarns 11 as shown in Figure 2. The handle part is basically composed of the droppers 2 _a , 2 _b , and as shown in Fig. 3.
2 _c , 2 _d and the pattern threads 12 _a , 12 _b , 12 _c , 12 _d are in respective related positions, and the pattern threads 12 _a , 12 _b , 12 _c ,
The threads 12 and _12d are threaded through the frantine guide 1, and the frantine guide bar 3 provides insertion movement between the two needles.

G ₁ to G ₄ indicate the positions of each gauge, and in order to knit gauge G ₁ with hole-based knitting, drop the dropper 2 _a at the A course, and transfer the pattern thread 12 _a to the pattern thread 1.
2 _a ′, and raise the dropper 2 _b between gauge G ₂ on the B course.

In addition, in order to knit thick fabric between gauges _G2 , the dropper _2b is raised in the A course, the dropper _2c is lowered in the B course, and the pattern thread _12c is changed to the pattern thread _12c '.

Furthermore, in order to knit a thin fabric between gauges _G3 , the dropper _2c is raised in the A-th course, and the dropper _2d is raised in the B-th course.

That is, to determine the knitting method between certain gauges,
For the dropper that moved up and down in the A course, B
In the second course, it is necessary to move up and down the adjacent dropper that was activated in course A (in this case, the one on the right).

However, with the above-mentioned method of moving the bottom plate up and down, it is possible to freely move the droppers to the left and right working positions corresponding to each gauge, so the hole on the card corresponding to one dropper can be adjusted as appropriate depending on how the hole on the card is knitted. However, in the dropper control method using the upper and lower knife frames described later, the operating position of the dropper cannot be changed as described above.
It was not possible to adopt the conventional method.

The present invention provides a method for punching a Jacquard card in order to adopt a new mechanism capable of controlling vertical needles by moving the knife frame up and down.
The figure shows a partial plan view of a Jacquard card 10 manufactured by the perforation method of the present invention, 13 is an A card, and droppers 2 _a , 2 _b , 2 are arranged according to the pattern configuration of the A course in FIG. 3 . _c and 2 _d control the folding part on one side of the pattern thread, and 14 is a B card which also controls the pattern thread by droppers 2 _a , 2 _b , 2 _c , and 2 _d according to the pattern configuration of the B course. A hole is drilled to control the folded part on the other side.

If 15 is the drilling position for controlling the A-th course of gauge G ₁ , then the drilling position for controlling the B-th course of gauge G ₁ may be 19, and in this way, the drilling position of the B card is the same as that of the A card. The position may be shifted by one gauge.

Therefore, in the case of gauge G ₂ , the A card is 16,
If the B card is 20, and the gauge is G ₃ , the A card is 17 and the B card is 21. If the gauge is G ₄ , the A card is 18 and the B card is 22.

As mentioned above, in order to determine the knitting method for the gauge with respect to the perforation position for controlling the A course of gauge G ₁ , it is necessary to control the dropper 2 _b of the adjacent gauge G ₂ at the B course. However, the knitting method is determined by the original gauge G ₁ , so the combination of perforated and non-perforated is this gauge G ₁
Judge by.

For example, the A card has a perforation or non-perforation command for the dropper 2 _a corresponding to gauge G ₁ based on the knitting method, and the B card has a perforation or non-perforation instruction for the dropper 2 _b corresponding to gauge G ₂ based on the knitting method. The punching position for the punching command for the B card is shifted by one gauge from the punching position for the punching command for the A card.

As described above, when forming a pattern using a jacquard drassier machine, the present invention provides a punching position of the A card that controls the position of action of the A course of the pattern thread, and a B card that controls the position of action of the B course of the pattern thread. If a jacquard card is used which is formed by the perforation method of the present invention in which the perforation position is shifted by one gauge, the control of the dropper corresponding to the knitting method can be configured as a perforation command for each gauge. As a result, a jacquard device that allows the droppers to fall between fixed flanches can be used in a jacquard lattice machine, which allows knitting to be carried out smoothly and effortlessly, as well as increasing the rotational speed of the knitting machine. This will produce ground-breaking effects that will lead to further development.
