Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method and apparatus for manufacturing a braid formed by intertwining a number of braid threads with each other.

BACKGROUND OF THE INVENTION Conventionally, a device for manufacturing this type of braid consists of forming grooves that intersect in a zigzag pattern on a base, through which carriers pass, and attaching a large number of carriers to the grooves, and then attaching the carriers to a plurality of gears meshing with each other. The carriers are transferred one after another by a gripping member and moved along the groove, and the braided threads fed out from the carriers are entwined to form a braided cord with a predetermined structure.

Problems to be Solved by the Invention However, with this device, the texture of the braid that can be produced is determined for each lace-making machine, and a single lace-making machine can only produce strings with a very limited number of types of textures. .

Furthermore, braided cords can be roughly divided into round braided cords and flat braided cords, but in the case of round braided cords that have a large number of carriers, the braided cord becomes tubular and has a space inside. Therefore, if left as is, the braid will be too flexible and the structure will not be stable.Therefore, a round braid with a large number of carriers is often used as a core braid by inserting a large number of core threads into it. Braided cords have many uses, but in general, the behavior of the core thread and the braided cord when stretched is different, and compared to ropes, etc., the strength is inferior even if the thickness is the same.

The present invention was made in view of the above circumstances, and the structure of the braid is not limited, and any structure of the braid can be freely formed. It is an object of the present invention to provide a novel method and apparatus for manufacturing a braid, which can also produce a cylindrical braid organized in a cylindrical shape.

As a means for solving the problem, the method of the present invention is to place a large number of movable bodies slidably on the surface of a plate, attach bobbins wound with braided yarn to the movable bodies, and attach each of the movable bodies to the movable bodies. of the plate,
By magnetically attracting a conveying member provided on the back surface and moving the conveying member along a predetermined path on the back surface of the plate, the corresponding moving body is moved along the same path on the surface of the plate. The present invention is characterized in that the braided yarn fed out from the movable body is entwined with a desired braided fiber. Further, in the device of the present invention, a large number of movable bodies are slidably placed on a plate made of a non-magnetic material, a bobbin on which a thread is wound is attached to the movable body, and the bobbin facing the movable body is A conveying member is disposed below the plate, the conveying member and the moving body are coupled by magnetic force, and a driving means is attached to the conveying means to move the conveying means along a predetermined route. A pair of plates are fixed in parallel to each other via a spacer, the movable body is slidably placed on the upper plate, and the conveying member is arranged under the lower plate. , an intermediate member is placed between both plates,
It is preferable that magnets with opposite polarities are attached to opposing surfaces of the intermediate member and the movable body and conveyance member, respectively.

Operation Next, the present invention will be explained in detail. In the present invention, the movable body is slidably placed on the plate, and its sliding path and range are not restricted by grooves, etc., and can freely move on the plate. It can be moved and stopped as needed.

On the other hand, the conveyance member that moves the moving object moves under the plate without any obstacles, and is driven along a free path by a drive means of an appropriate structure (for example, a structure similar to an X-Y plotter or a magic hand). It is possible to move.

When the conveying member is moved along a predetermined path along the lower surface of the plate by a driving means controlled by a computer, the conveying member attracts the moving body by magnetic force, and the moving body is attached to the conveying member on the upper surface of the plate. It is pulled and slides along the same path. The braided threads wound around the bobbin are then unwound from the bobbin attached to the movable body, and these braided threads intertwine along the path of the movable body to form a braid of a desired structure.

Example Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 schematically shows a braid manufacturing apparatus of the present invention. In this device, 1 is a frame, and a plate 2 made of a non-magnetic material such as aluminum is fixed to the frame 1. A large number of moving bodies 3 are placed on the upper surface of the plate 2.

Next, the structure of this moving body 3 will be explained according to FIG.

The plate 2 has an upper plate 2a and a lower plate 2b.
They are separated into two parts and fixed in parallel to each other at regular intervals by spacers 4. The transfer #J body 3 has a running member 5 at its lower part, a magnet 6 is embedded in the center of the lower surface of the running member 5, a thrust bearing 7 is attached around the magnet 6, and the thrust bearing 7 allows it to slide smoothly on the upper plate 2a.

A support member 8 is fixed to the upper part of the traveling member 5, and a bobbin 10 on which a braided thread 9 is wound is attached to the support member 8. At the upper part of the support member 8, there is a yarn guiding portion trJi that guides the braided yarn 9 paid out from the bobbin 10.
11.12 are installed. The braided threads 9 are unwound from the bobbin 10, guided by thread guiding members 11 and 12, and extend upward, intertwining with each other to form a braided cord.

In the drawing, 13 is provided above the plate 2.
This is a die for forming the braid 14 into a predetermined shape.

15 is an intermediate member inserted between the upper plate 2a and the lower plate 2b. Magnets 16 and 17 are embedded in the centers of the upper and lower surfaces of the intermediate member 15, respectively, and the magnet 16 on the upper surface and the magnet 6 of the traveling member 5 have opposite polarities and are attracted to each other. ing.

Further, thrust bearings 7 are attached around the magnets 16 and 17 on both the upper and lower surfaces of the intermediate member 15, so that they slide smoothly along the lower surface of the upper plate 2a and the upper surface of the lower plate 2b.

Further, reference numeral 18 denotes a conveying member provided below the lower plate 2b, in which a magnet 19 having a polarity opposite to that of the magnet 17 on the lower surface of the intermediate member 15 is embedded in the center of its upper surface, and around this is a thrust bearing 7. is attached so that it slides smoothly along the lower surface of the lower plate 2b.

Furthermore, this conveying member 18 is attached to the tip of a driving means (not shown), and is configured to move along the lower surface of the lower plate 2b according to a desired path. As this driving means, a device having an appropriate structure can be used.For example, a device having a structure similar to an X-Y grotter or a magic hand can be used, and these driving devices are caused to perform a predetermined operation. It can be controlled by a computer.

When the conveying member 18 is moved along a predetermined path by this driving means, the magnet 1 of this conveying member 18
9 attracts the magnet 17, and the intermediate member 15 moves together with the conveying member 18. Furthermore, the magnet 16 on the upper surface of the intermediate member 15 attracts the magnet 6, and the movable body 3 moves together with the intermediate member 15.

The braid 14 is organized by intertwining above the .

Note that the plate 2 is a single plate, and the traveling member 5 may be moved directly by the conveying member 18 by sandwiching the plate, but this plate is not large enough to make the magnetic force of the magnet work effectively. It is preferable that it be very thin; if it is made thin, when a large number of movable bodies 3 are mounted and moved, there is a risk that the movable body 3 may bend or be distorted due to its weight. Therefore, as in this embodiment, the two plates 28.2tl are fixed via the spacer 4, and the intermediate member 15 is
It is preferable to move the traveling member 5 via the.
