Description

[Detailed explanation of the idea] The present invention relates to a jacquard device installed in a warp knitting machine.

Conventionally, the hook part at the upper end is arranged approximately at right angles to the vertical needle which can be held on the knife, and the movement of the horizontal needle, which is partially engaged with the vertical needle, is selected depending on the presence or absence of perforations in the patterned paper. In a jacquard device for a warp knitting machine, in which the hook portion of the horizontal needle that is engaged with the moved horizontal needle is removed from the knife, the horizontal needle is moved by the reciprocating movement of the cylinder with the pattern paper interposed. However, in this case, the pattern paper is subjected to oscillation due to both the reciprocating motion and the intermittent rotational movement of the cylinder, which makes it difficult to increase the rotation of the jacquard device, and also causes the paper surface to oscillate. Since the load placed on the pattern paper increases as the horizontal needle is directly pressed and moved, the pattern paper itself needs to be strong and thick enough to be made, so a thin single sheet of pattern paper cannot be used. It was necessary to bind each card with braided cord, making the process of preparing the pattern paper time-consuming.

The present invention has been made in order to eliminate the above-mentioned drawbacks.

Next, the present invention will be explained in detail based on example diagrams.
1 is a vertical needle, 2 is a bottom plate fixed to the machine frame, 3 is a knife frame plate, and the bottom plate 2 has holes 4 arranged vertically and horizontally in correspondence to the number of vertical needles 1. A knife 5 is hung horizontally on the knife frame plate 3 and fixed at both ends. An integrally provided connecting rod 6 is inserted into the hole 4 of the bottom plate 2.

7 is a horizontal needle, 8 is a sliding mesh plate, and 9 is a side plate. It is inserted through the horizontal needle 7, and is engaged with the vertical needle 1 by a bent portion 7a provided on a part of the horizontal needle 7.

Reference numeral 7b denotes an engaging portion projecting from the end of the horizontal needle 7 on the side of the feed sprockets 1 to 10.

10 is a feed sprocket fitted to the fixed shaft 11, 12 is a guide plate, 13 is a pattern paper, 14 is a presser plate, and the guide plate 12 has a trapezoidal cross section and corresponds to the tip of the horizontal needle 7. A holding plate 14 is installed at a distance from the guide plate 12, holding the patterned paper 13 between them, and the patterned paper 13 is formed by pointed pins protruding radially from the outer periphery of the feed sprocket l-10. 15 and the feed sprocket 10
By the intermittent rotation, one piece of pattern paper, that is, one area of pattern paper having an area that can be perforated by the number of horizontal needles 7, is sent to a position corresponding to the horizontal needles 7.

16.16 is a sliding shaft, and the sliding shaft 16.16 has a sliding tube 18. in which a plurality of balls 17 are rotatably embedded.
18 is loosely fitted and is inserted and supported by bearings 19 and 20,
A sliding eye plate 8 is supported and fixed at one end of the sliding shaft 16.16.

Reference numeral 23 denotes a drive arm, which has an eccentric ring 22 fitted onto a drive shaft 21 that rotates in synchronization with the weaving, and is connected to the sliding shaft 16 via a connecting pin 24 by a connecting member 25. There are one set on each side.

The above is the configuration of the jacquard device according to the present invention.
Next, to explain its operation, the drive arm 23 is driven by the rotation transmitted to the drive shaft 21 from the driving shaft (not shown) of the warp knitting machine, and the sliding shaft 16 moves in the direction A shown in FIG. At the same time as sliding, the sliding eye plate 8 also moves in the A direction, but at this time, due to the engagement between the engaging portion 7b of the horizontal needle 7 and the sliding eye plate 8, the horizontal needle 7 moves entirely in the A direction. At this time, the fixed shaft 11 is rotated by an angle equivalent to one sheet of pattern paper in synchronization with the rotation of the driving shaft, and at the same time the pattern paper is rotated by the pointed pin 15 of the feed sprocket 10. is sent so that one area in which a specified hole has been made comes into contact with the guide plate 12, and then the sliding shaft 16 is returned to the direction B, but at this time, the part of the horizontal needle 7 on the pattern paper 13 comes into contact with the guide plate 12. If there is no perforation, it will not return to its original position and will be stopped midway, and the vertical needle 1 will be pushed by the bent part 7a, and the hook part 1a will be removed from the knife 5 and placed on the pattern paper 13. The one with a perforation has a hook portion 1b that engages with the knife 5,
When the knife frame plate 3 moves upward with the horizontal needle 7 selected in this way, only the vertical needle engaged with the knife 5 is lifted, and at the same time the connecting rod 6 is lifted. It will perform the function of a jacquard device.

In this way, the information on the pattern paper 13 is converted into the vertical selection movement of the connecting rod 6 by the mutual movement of the vertical movement of the knife frame plate 3, the left and right reciprocating movement of the sliding mesh plate 8, and the intermittent rotational movement of the feed sprocket 10. It is.

As described above, the present invention does not move the horizontal needle directly through the pattern paper using a guide member such as a cylinder, as in the past, but the horizontal needle is first engaged with the retaining part of the horizontal needle using a sliding plate. Since the pattern paper is spaced further apart and is configured so that one sheet of the pattern paper is transported by the feed sprocket, the pattern paper only needs to be rotated intermittently in the feeding direction, and therefore less vibration is applied to the pattern paper. It is possible to increase the rotation of the device, and since the pattern paper does not involve the movement of the horizontal needle, it is possible to prevent misalignment between the horizontal needle and the pattern paper hole. It can be made thinner, and moreover, it can be reliably engaged with the horizontal needle, so by making the perforation hole smaller, the area of one card can be reduced, and as a result, the weight of the pattern paper as a whole can be reduced, and the continuous It has various practical effects, such as the effect of using a single sheet of patterned paper.

Claims (1)

[Scope of utility model registration request] The movement of the horizontal needle, which is located approximately perpendicular to the vertical needle that can be freely attached to the knife at the hook part at the upper end and is partially engaged with it, is selected depending on whether or not there is a perforation in the pattern paper. In a Jacquard machine of the type in which the hook portion of the vertical needle that is engaged with the horizontal needle is removed from the knife, a feed sprocket 10 is provided on a fixed shaft 11 so as to be able to rotate intermittently, and the feed sprocket of the horizontal needle 7 is A sliding eye plate 8 is provided that circumscribes the retaining portion 7b provided protrudingly at the end of the sprocket 10 and is slidable in synchronization with the rotation of the feed sprocket 10. The sliding eye plate 8 allows the engagement portion 7b to A jacquard device for a warp knitting machine, characterized in that the jacquard device for a warp knitting machine is constructed such that when all the needles 7 are moved away from the pattern paper 13, branches of the pattern paper 13 can be conveyed by the feed sprocket 10.
