BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warp knitting machine having a jacquard guide bar, the jacquard guide bar having two rows whose position can be moved by a support member and a pushing element controlled according to the pattern. Guide needle (
and a first guide block in the first row and a second guide block in the second row, each of these guide blocks being adjacent to each other in the longitudinal direction. are arranged and connected to a guide bar, each guide block holding a predetermined number of said rows of guide needles, guiding the associated pusher element and directing the movement of the guide needles. Has a stopper for restriction.

[Prior Art and Problems to be Solved by the Invention] Such a warp knitting machine is known as the "Kettenwirk-Praxi"
Warp knitting machine RJSG4 of the applicant described on pages 7 to 10 of issue 4/87 of ``S (Kettenbirk Praxis)''
Known by F-NE. This warp knitting machine is provided with a jacquard guide bar equipped with two rows of guide needles, a fall plate, and three guide bars equipped with fixedly attached guide needles in front and behind in the knitting direction. .

[0003] With this type, it is easy to access and work on the guide needle, the guide block holding it, the pushing element, and the harness cord on the front row side during repair.

However, repairing the rear (rear row) Jacquard guide bar takes much more time and expense than the front row. That is, the front row of Jacquard guide bars must be removed, which is very time consuming, as a large number of harness cords, each connected to the corresponding pushing element, must be disconnected and reconnected after repair. (approximately 50 hours) and also requires removing the fall plate behind the Jacquard guide bar and removing at least part of the guide bar, which also requires a long downtime. .

[0005] Moreover, it must be kept in mind that even if a problem occurs in just one guide needle, the above-mentioned troublesome repairs are forced.

The object of the invention is to propose a warp knitting machine of the type mentioned at the outset, which can be repaired very simply and quickly.

[0007]

[Means for Solving the Problems] According to the present invention, the second guide block is attached to the support member with the first guide block in between, so that the second row of guide needles can be This is achieved by arranging the member on the same side of the member as the first row of guide needles.

[0008]

[Function] With this structure, the second row of guide needles, which conventionally require a lot of time and money to repair,
Being placed on the same side of the support member as the first row of guide needles, the second row of guide needles can also be accessed and worked on very easily.

In this structure, the first guide block is covered by the second guide block, which means that the guide block is in any case a collection of small members with a length of 1 or 2 inches. This is not a serious problem as it is made up of several things. In other words, in order to replace the guide needles of the first row, it is only necessary to unscrew one second guide block located in front of it. However, at this time, it is necessary to uncouple the attached harness cord and remove the guide needle and pushing element of the second guide block. Its assembly can be carried out in reverse order, and repairs can be completed within an hour.

[0010] In this structure, a more effective structure is that the first guide block has a mounting wall on the side opposite to the support member, and a second guide that is a part of the Jacquard guide bar is attached to the mounting wall. The block is attached at its attachment site. This new design of the guide block ensures that in the direction of continuous swinging motion of the Jacquard guide bar,
A stable installation condition can be obtained in a small space.

A particularly advantageous and recommended construction is that the first guide block has a first lateral wall in which the guide needle is to be held and in which the pushing element is to be guided; a second lateral wall offset from the second lateral wall and in which a stop for limiting the movement of the guide needle is formed; an attachment part located between them and in contact with the support member; , and such that the mounting wall emanates from an extension of the first lateral wall and extends in a direction opposite to the guide needle.

[0012] This creates an attachment point at a relatively large distance from the hole portion of the guide needle. Sufficient space is provided to provide a stable mounting arrangement in the direction of continuous swing motion, and
In addition, the space radially outside the guide needle is available for mounting.

It is further advantageous that at least one mounting screw passes through the mounting portion of the second guide block and the mounting wall of the first guide block, and is mounted together with a threaded element provided behind the mounting wall. It is to function in This separately provided screw element avoids a structure in which a screw hole must be provided in the mounting wall of the first guide block. As a result, when the mounting points of the guide and holder of the guide needle and pushing element are formed as slits, which is a well-known method, the mounting points are located in close proximity to the slits, and the slit processing tool is placed in front of the mounting points. Or even if it partially penetrates, there will be no problem.

[0014] In the case of independent nuts, it is necessary to use a tool to hold each nut on site and tighten the screws while preventing rotation, but a plate having multiple screw holes as a screw element is used. By using , you can avoid such complicated work. Such a plate can be extended over several guide blocks and reliably retains the screw holes in the field during repairs.

It is also advantageous for the second guide block to have a stop which works together with the first guide block to determine the height position of the guide block relative to each other.

[0016] Thereby, the position of the guide needle can be determined with high precision during operation.

[0017] Furthermore, if the Jacquard guide bar is provided as the frontmost guide bar and the first and second rows of guide needles are held in front of the Jacquard guide bar, it is easy to access and work on the guide needles. The simplest configuration is obtained.

[0018] When two similar Jacquard guide bars are provided, each Jacquard guide bar is preferably arranged such that the rows of guide needles provided on one side of the Jacquard guide bars are located opposite each other; With this configuration, when repairing the guide needle, the repair work can be performed without disassembling the Jacquard guide bar.

The first guide block 8 is attached to the support member 2 by screws (bolts) 14, and in this attachment, a stopper 15 contributes to accurate positioning.

Similarly, the second guide block 9 is attached to the first guide block 8 by screws (bolts) 16, and in this attachment, a stopper 17 contributes to accurate positioning.

The first guide block has a mounting wall 18 on the side opposite to the support member 2, and this mounting wall 18 has the second
A guide block attachment portion 19 is attached. The screw 16 is screwed into a screw hole 20 of a screw element 21, which is formed of a plate having a plurality of screw holes 20, and therefore has a plurality of second screw holes 20.
This is common to the guide block 9.

The mounting wall 18 is provided at the open end of the lateral wall 22. This lateral wall 22 is provided with a number of slits 23, which for manufacturing reasons are also formed in the mounting wall 18. The pushing element 10 is guided in these slits 23, and the guide needle 4 is held, which is held by a wire 24 and a stopper 2 in a well-known manner.
This is done by 5. This wire 24 is connected to the hole 26

The pushing element 11 is held in a stable state in a complementary manner by a wire 45 passing through a slit 46 and a hole 47 therein.

The lateral wall 48 at the lower end has a relatively wide slit 49, which, like the slit 35 with the side wall described above, has a stopper a for the movable guide needle 6.
, b. The wire 50 complementarily holds and stabilizes the position of the guide needle 6.

The first and second guide blocks 8 and 9 each hold the same number of guide needles 4 or 6. These guide needles 4 and 6 stop at a gap between each other in the rest position state, so the needle pitch is determined by the distance between the odd-numbered guide needle and the even-numbered guide needle adjacent thereto. Determined by interval. In this way, for example, 28E(
28 gauge), or 28 needles per inch, can be obtained.

[0033] Even in that case, there is sufficient space for movement.

[0034] Also, by providing a relatively large needle interval, the first row and the second row can be knitted with two different types of knitting yarns.
It is also possible to mutually adjust the guide needles of the rows.

[0035] Then, if the guide needle 6 or the pushing element 11 has to be replaced, this
