BACKGROUND ART [0002] Generally, in forming a seat of an automobile, a cover made of artificial leather or the like is detachably attached to an injection molded article having a shape of a seat.

A detachable fastener is used to detach and attach such a cover.

The first fastener, which is a part of the detachable fastener, is bonded to the surface of the injection molded article in an in-mold manner during the molding process of the injection molded article, and the second fastener mated with the part is attached to the cover, As shown in FIG.

The first fastener, which is normally imbedded in the surface of the article of manufacture, is formed by uniformly dispersing a large number of hooks on the base, and the second fastener engaged with the sheet is provided with a number of loops or anchors Are uniformly dispersed and formed.

The first fastener, which is inlaid in the injection-molded article, covers a sponge made of a synthetic resin material having a good cushioning property along the edge of the first fastener, including the top of the hook, in order to prevent the injection product from intruding into the hooks during the molding process. This is because, when the injection material infiltrates into the hook during the injection process, the hook and loop engagement efficiency becomes poor.

Japanese Patent Application Laid-Open No. 10-2011-0070132 and the like disclose a conventional in-use fastener for attaching a sponge to the edge of the fastener.

However, in the conventional in-mold fastener, there is a problem in that it is necessary to attach the sponge to both sides of the fastener with a force or the like, thereby causing a lot of sponge.

In addition, this has made it difficult to mass-produce and raise the unit price due to labor costs.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a fastener for slit sponge, And it is an object of the present invention to provide an apparatus for manufacturing an in-mold fastener which can reduce the unit cost.

The sponge winding portion 20 is a portion around which a sponge 1b whose fabric is coated with an adhesive on one surface and to which the release paper 1c is adhered is wound.

The release paper 1c prevents the sponge 1b from being adhered to the sponge 1b by the adhesive applied to the sponge 1a before the sponge 1b is adhered to the fastener 1a.

2, the first slitting unit 30 slits the sponge 1b supplied from the sponge winding unit 20 into a plurality of slits in a longitudinal direction.

The first slitting portion 30 includes a first slitting roller 31 and a first support roller 32 as shown in FIGS.

As shown in FIG. 3, the first slitting roller 31 is formed with a plurality of first blades 31a at regular intervals along the circumferential direction.

The second support roller 82 is disposed below the second slitting roller 81 to support the second blade 81a.

The sponge 1b having the same width is provided on both sides of the fastener 1a by cutting the middle portion of the sponge 1b adhered to the fastener 1a at a predetermined interval in the second slitting portion 80, It is possible to mass-produce the bonded in-mold fastener 1.

In addition, loss caused by the sponge 1b can be minimized.

The size of the sponge 1a attached to both side surfaces of the first slitting portion 30 may be slightly reduced before the sponge 1b loss occurs in the second slitting portion 80, It can also be done.

The scraps generated on both right and left sides of the fastener 1a are separately moved while being slitted in the second slitting portion 80 and moved to the scrap box C as shown in FIG.

The feed roller 55 serves to move the in-mold fastener 1 slitted in the second slitting portion 80 so as to be cut to a predetermined length.

1 and 2, the cut portion 90 cuts the slitted in-mold fastener 1 fed by the feed roller 55 to a desired length.

The cutting portion 90 is vertically movable in a direction perpendicular to the longitudinal direction of the in-mold fastener 1, and the lower portion of the cut portion 90 supports the cutting edge 91 92 are formed and the cutting blade 91 moves in the vertical direction to cut the in-flow fastener 1 to a desired length.

The first tension roller 110 is disposed at the front end of the release paper separator 60 to adjust the tension of the slit sponge 1b.

The first sliding part 120 slides the first tension roller 110 in the vertical direction.

When the tension of the slanting sponge 1b is loosened, the first tension roller 110 moves downward by the gravity along the first sliding portion 120, and the slanting sponge 1b moves downward And is prevented from being slackened or broken when moving from the first slitting portion 30 to the releasing paper separating portion 60 or the like.

The first sensor unit 130 includes a plurality of sensors 131 disposed on the first sliding unit 120 and sensing the position of the first tension roller 110.

That is, the sensor 131 located at the lower part of the first sensor part 130 moves downward from the first sliding part 120 to prevent the sponge 1b from slipping, The sensor 131 located at the upper portion senses the position of the first tension roller 110 so as to prevent the first sliding portion 110 from being broken when the sponge 1b is slid, 120 to detect the position of the first tension roller 110 moved upward.

The first control unit (not shown) controls the speed of the first driving motor M driving the first slitting unit 30 according to a signal from the first sensor unit 130.

The first control unit controls the first tension roller 110 to move the first sliding unit 120 in response to a signal from the first sensor unit 130 disposed on the first sliding unit 120, The speed of the first driving motor M driving the first slitting part 30 is reduced.

That is, when the first control unit senses the first tension roller 110 from the sensor 131 located below the first sensor unit 130 of the first sliding unit 120, The speed of the first driving motor M driving the rotating part 30 is lowered so that the slitted sponge 1b is pulled and the first sensor part 130 of the first sliding part 120 The speed of the first driving motor M driving the first slitting part 30 is increased to detect the first tension roller 110 in the upper part of the sensor 131, (1b) is not cut off.

The first control unit controls the first tension roller 110 in a lower portion of the first sliding unit 120 by a signal of the first sensor unit 130 disposed on the first sliding unit 120, The speed of the first driving motor M is decreased as the position of the sponge 1b is increased, thereby preventing the slitted sponge 1b from being broken or sagged.

The second tension roller 210 is disposed at the front end of the conveying roller 55 to adjust the tension of the slit in-mold fastener 1.

The second sliding portion 220 slides the second tension roller 210 up and down.

The second sensor unit 230 includes a plurality of sensors 231 disposed on the second sliding unit 220 and sensing the position of the second tension roller 210.

The second sensor unit 230 senses the position of the second tension roller 210 which is moved by the gravity in the vertical direction on the second sliding unit 220.

To this end, the second sensor unit 230 is provided with a plurality of sensors 231 in the vertical direction in the second sliding unit 220.

The second control unit (not shown) operates the cutting unit 90 according to a signal of the second sensor unit 230, which is composed of a plurality of sensors.

The apparatus for manufacturing an in-line fastener of the present invention is not limited to the above-described embodiments, but can be variously modified and embodied within the scope of the technical idea of the present invention.
