Description

  The present invention relates to a method of manufacturing a braided sleeve used for insulation, wiring, thermal protection, mechanical protection, hose protection, or electromagnetic wave shielding in, for example, home appliances, heavy electrical appliances, and automobiles. In particular, the present invention relates to a material that enables insertion of a wire or the like from a side surface that can be expanded and has improved insertability.

Conventionally, as a device for manufacturing such a braided sleeve, for example, a base (deck plate) having a central hole and fixedly arranged, and formed on the base, each of which has a corrugated shape and is formed in a shape of 8 with each other. The first and second pair of annular raceway grooves extending in the circumferential direction of the pedestal while intersecting each other, and the first raceway groove and the second raceway groove are inserted into the first raceway groove and the second raceway groove so as not to rotate relative to each other. From a bobbin having a foot with a guiding portion guided to travel while being regulated in direction by the second track groove, and having a bobbin shaft and a wire drawing hole, and rotatably mounted on the bobbin shaft A plurality of sets of first and second pairs of carry, which are relatively reversely run along the first raceway groove and the second raceway groove while pulling the wire from the lead hole, and the carry And a drive device for driving the carriage. Winding wire rods drawn from each carry as the vehicle runs in a spiral manner on the outer circumferential surface of a flexible elongated body that passes through the center hole of the frame and moves relative to the axis of the frame. In the wire braiding apparatus for braiding, a lead-out hole in the carry is provided in a fixed state at a position near the center of the gantry in a direction perpendicular to the traveling direction of the carry with respect to the axial center position of the guide portion ( Patent Document 1).

  However, in the above-described conventional braided sleeve manufacturing apparatus, since it is braided in an annular cross section, it has the advantage of excellent flexibility, elasticity, and stretchability, but in order to cover the braided sleeve on a wire such as a cable, It is necessary to insert a wire rod into the braided sleeve. Therefore, when a braided sleeve is applied to a long wire rod, considerable time and labor are required.

  In addition, the tip of the wire is not necessarily gentle, and may be caught in the middle of the sleeve, so there is a problem in workability. Further, when the wiring is already laid, the wiring is inserted into the braided sleeve. Since the work cannot be performed, there is a problem that the braided sleeve cannot be covered as it is.

  The present invention has been made in view of such conventional problems, and by making it possible to insert the wire from the side instead of the end of the sleeve, the insertability is improved and workability is improved. An object of the present invention is to provide a method of manufacturing a braided sleeve that can be easily covered with a laid wire or the like, and a manufacturing apparatus therefor.

  In order to solve the conventional problems as described above and achieve the intended object, the structure as the gist of the present invention is a first and second pair of annular grooves intersecting each other in the shape of a figure 8 on the surface of the gantry. In the manufacturing method of a braided sleeve in which a sleeve having a predetermined diameter is braided while running a plurality of bobbins in the circular raceway groove, the circular raceway groove is formed in a plane spiral shape from the outer periphery of the gantry to the center part. In addition, a braided sleeve manufacturing method is characterized in that a plurality of bobbins are spirally run while repeating U-turns at both ends of the circular raceway groove to be braided in a cross-sectional shape.

  In addition, the bobbin preferably travels in the orbital groove through the geared carry, and the bobbin is transferred by aligning the connecting grooves of the adjacent geared carry by rotation of gear 90 degrees.

  On the other hand, a braided sleeve manufacturing apparatus according to the present invention for carrying out this manufacturing method is capable of traveling through a spiral circumferential track groove formed in a gantry and a geared carry in the spiral circumferential track groove. A plurality of attached bobbins, and a guide having a predetermined outer diameter disposed above the mount for converging the wire wound around the bobbins, and the bobbin travels in the spiral orbital groove By doing so, it is characterized in that it is braided in a cross-sectional shape on the peripheral surface of the guide.

  Furthermore, the wire is one or two of polyethylene terephthalate (PET), polyethylene (PE), nylon, polybutylene terephthalate (PBT), polypropylene (PP), and metal wire having a wire diameter of 0.1 to 0.5 mm. A composite yarn knitted with the above combination is preferable.

  The present invention is configured as described above, and a plurality of bobbins travel along a circular spiral orbital groove formed on the pedestal, and then, above the pedestal to focus the wire wound around the bobbin. By braiding the sleeve into a cross-sectional shape on the circumferential surface of the guide having an outer diameter of a predetermined dimension, it is possible to easily form the cross-shaped sleeve so that insertion of a wire or the like can be performed from the side surface, etc. In addition, it is possible to facilitate the operation of inserting wires and the like, and since it can be produced simply by changing the frame of the conventional braiding device, it has the advantage of being very economically advantageous.

  A spiral orbital groove formed on the gantry, a plurality of bobbins attached to the spiral orbital groove through a geared carry, and the wire rod wound around the bobbin to converge A guide having an outer diameter of a predetermined dimension disposed above the gantry and a heater that heats the sleeve to stabilize the shape thereof.
