Description

Curl fabric making device {MANUFACTURING DEVICE FOR CURLED FABRIC}

The present invention relates to an apparatus for producing a curled fabric for producing a curled fabric for fabrication with a protective sleeve, in a flat form fabric.

Protective sleeves are used in the automotive, marine and aviation industries to systematically protect elongated articles, such as wire harnesses and fiber optic cables. This sleeve surrounds the elongated article to protect it from vibrations that cause cutting, wear, radiant heat, wear, and other severe environmental threats. When placed in a protective sleeve, the wires or cables are held together in a neat bundle so that a number of different items can be processed into sub-assemblies, thereby saving time and effort during the integration of those items into the product. do.

The protective sleeve can be made by weaving the filaments into the substrate and then elastically biasing the substrate into a tubular form to form a central space for accommodating the elongated article. Biasing can be done by a variety of means suitable for the types of yarns used to make the substrate. The polymer filaments can be biased by heating when the substrate is wound around a cylindrical mandrel, which filaments will take a permanent set that matches the shape of the mandrel. In addition, the filaments can be elastically biased into a dried shape by chemical means or cold working.

1 is a conceptual view of a fabric in the form of a plate, Figure 2 is a perspective view of a protective sleeve manufactured in the state of the product is cut into a predetermined length after the flat form of the fabric of Figure 1 is rolled.

In order to form such a flat fabric into a curled fabric, the fabric must be heated to a predetermined temperature and then cooled to a dried form.

However, as seen in FIG. 2, the curled fabric has a form in which one end of the width direction and the other end of the width direction are overlapped (in the case of FIG. 2, 180 degrees overlapped). The part located outside and the part located outside have different cooling speeds, and if it is not kept long enough in a dried form, it becomes a factor of product shape defect.

This mismatch in cooling rate is also a problem when fabricating protective sleeves individually, but it is a major cause of product shape defects, especially in the case of continuous fabric fabrication.

The present invention relates to a curling fabric manufacturing apparatus for molding a flat fabric as shown in Figure 1 in a dried form as shown in FIG.

The manufacturing apparatus is largely unwinding unit 100, steam preheating unit 200, heating unit 400, forming block 500, inner and outer cooling unit 610, 620, take-out unit 700, cutting unit ( 800).

First, the unwinding part 100 on which the flat fabric 10 is wound is provided.

Unwinding portion 100 is released from the flat plate-shaped fabric 10 wound thereon by the pulling force from the take-off portion 700 to be described later.

The fabric released from the unwinding part 100 first enters the steam preheating part 200.

Steam preheating unit 200 is made of a steam heating tube is supplied with steam, the fabric is pre-heated by the supplied steam.

The fabric 10 is then guided to the upper position by the guide roller.

The fabric 10 guided to the upper position is sequentially passed through the guide jig 300, the heating unit 400, the forming block 500, the inner cooling unit 610 while descending to the lower portion.

That is, the guide jig 300, the heating part 400, the molding block 500, and the inner cooling part 610 are sequentially disposed from the top to the bottom direction.

The guide jig 300 is formed with a G-shaped guide hole 301. By the G-shaped guide hole 301, the flat fabric is passed through the guide jig 300 in a dried form.

The fabric past the guide jig 300 then passes through the heating unit 400.

The heating unit 400 of the present embodiment is made of two tubular heaters 410 disposed in a row in the vertical direction, and the fabric heating passage 411 formed in the vertical direction at the center of the tubular heater 410. ) Is formed.

In the tubular heater 410 of the present embodiment, a band heater was used.

Accordingly, the fabric 10 is rapidly heated by the radiant heat of the heater 410 while passing through the fabric heating passage 411. Meanwhile, the fabric 10 passes through the fabric heating passage 411 but direct contact with the heater 410 should be prohibited. That is, the fabric heating passage 411 should have a larger diameter than the dried form of the fabric (10).

The fabric 10 passing through the heating unit 400 is molded into a curled fabric while contacting the forming block 500.

The molding block 500 extends while the molding opening 510 has the same cross-sectional structure in the vertical direction.

The molding opening 510 is a portion which is opened in a dried form so as to correspond to the cross-sectional structure of the curled fabric.

In addition, the outer end 511 of the molding opening 510 of this embodiment is open.

Thus, the fabric 10 can be easily attached to the molding opening 510 through the outer end 511 in preparation of the manufacturing process.

In the manufacturing process, the outer end 511 of the molding opening 510 is blocked by the guide permanent magnet 520 to prevent the fabric 10 from being separated to the outer end 511.

That is, the guide permanent magnet 520 is detachably magnetically coupled to the forming block 500 to prevent the mounting of the fabric 10 and the detachment of the fabric.

Thus, the fabric 10 is molded due to the shape of the molding opening 510 while passing through the molding opening 510.

The fabric 10 past the forming block 500 then passes through the inner cooling section 610.

The fabric passing through the inner cooling unit 610 should be cooled while maintaining the form after passing the forming block 500.

The inner cooling unit 610 is provided to cool the inside of the fabric 10 in particular.

The inner cooling unit 610 is formed by rolling a metal tube having excellent thermal conductivity.

Due to the dried structure of the inner cooling unit 610, the fabric passing through the forming block 500 is cooled while passing between the dried metal tubes while maintaining their shape. The fabric is then cooled in direct contact with the metal tube.

In addition, a cooling air injection hole 611 through which cooling air is injected is formed at the inner end of the metal tube.

Cooling air injected into the metal tube from the outside not only cools the metal tube itself but is also injected into the fabric 10 by the cooling air injection holes 611 to cool the inside of the fabric 10.

On the other hand, a stopper 612 is provided inside the metal tube to limit the position of the fabric.

In addition, the outer side of the inner side cooling unit 610 is provided with an outer side cooling unit 620 for injecting cooling air from the outside of the fabric (10).

As described above, in the present embodiment, the fabric formed by the inner cooling unit 610 and the outer cooling unit 620 may be uniformly cooled to prevent defects in the form of the product.

As described above, when the fabric passing through the inner cooling unit 610 is cut to a predetermined length, a protective sleeve in a product state may be manufactured.

To this end, a take-up part 700 for pulling the curled fabric may be provided at the rear end of the inner cooling part 610, and a cutting part for cutting the curled fabric to a predetermined length at the rear end of the take-off part 700 ( 800 may be provided.
