Particularly, the interlayer peeling apparatus 100 according to the present invention is a facility for separating the interlayer (interlayer) from the end of a multi-plastic tube 10 (hereinafter, referred to as a "tube" This is to initially delaminate the interlayer adhesion of the tube 10.

The main body 210 forms an outer shape of the delamination apparatus 100 and supports or connects the lower jig 220, the upper jig 230, the cutter 240, and the cutter height adjuster 330 . At this time, the main body 210 can be deformed into various shapes.

The lower jig 220 is provided on the main body 210 to support the relief tube 10. At this time, the lower jig 220 can be deformed into various shapes.

The upper jig 230 is provided on the main body 210 so as to move upward and downward to press and fix the tube 10 placed on the lower jig 220. Of course, the upper jig 230 can be deformed into various shapes.

The cutter 240 serves to peel off the layers of the tube 10 fixed by the upper jig 230 and the lower jig 220. Therefore, the cutter 240 is provided to the main body 210 so as to be linearly reciprocally movable. At this time, the cutter 240 can be deformed into various shapes.

For example, the tube 10 is formed in a linear shape such that the cutter 240 is inserted between the corresponding layers while being peeled from each other as the interlayer between the lower jig 220 and the upper jig 230 becomes substantially linear.

Particularly, the cutter 240 is reciprocally movable in the direction of the tube 10 fixed to the lower jig 220 and the upper jig 230, or vice versa, by the front and rear slide members 310.

At this time, the front and rear slide members 310 are movably supported by the main body 210 and are moved forward or backward in accordance with the rotational direction of the front and rear shaft 312. The front and rear shafts 312 are engaged with the front and rear slide members 310 so as to stably and finely adjust forward and rearward movement distances.

The front and rear slide members 310 are linearly reciprocally movable to the main body 210 by various methods such as an 'LM guide'.

The front and rear shafts 312 are provided with front and rear handles 314 to facilitate rotation. Thus, the operator operates the front and rear handles 314 to adjust the amount of rotation of the front and rear shafts 312 to set the forward and backward degrees of the front and rear slide members 310 and the cutter 240.

In addition, the front and rear slide members 310 are provided with the vertical movement blocks 320 so as to be moved up and down. In particular, the vertical movement block 320 is movable in the vertical direction with respect to the front and rear slide members 310 in various ways such as an 'LM Guide'. The vertical movement block 320 may be formed in various ways.

Further, the vertical movement block 320 fixes the cutter 240. Of course, the cutter 240 can be fixedly installed in the vertical movement block 320 in various ways. At this time, the cutter 240 may be provided in the up-and-down moving block 320 so as to be interchangeable.

The vertical movement block 320 includes a cutter height adjuster 330. Accordingly, the cutter height adjusting unit 330 moves forward or backward together with the front and rear slide members 310 to adjust the height of the cutter 240 and the vertical movement block 320 with respect to the front and rear slide members 310 .

In particular, the cutter height adjuster 330 adjusts the height of the cutter 240 to a set value to set the interlayer peeling position of the tube 10.

Here, the cutter height adjuster 330 includes a height supporter 332 and a height gauge 334.

The height supporter 332 is provided at a set position of the main body 210 or the front and rear slide members 310. Of course, the height supporter 332 can be deformed into various shapes.

The height gauge 334 is provided in the vertical movement block 320 and is movable in the downward direction of the vertical movement block 320 to adjust the degree of descent of the vertical movement block 320 according to the degree of pressing the height supporter 332 It sets up. That is, the height gauge 334 serves to display the pressing force of the position-fixed height supporter 332 to the operator when the pressing force reaches the set value. Here, the 'set value pressing force' can be set in advance at the beginning of the work.

Of course, the height gauge 334 can be deformed into various shapes.

The cutter height set by the cutter height adjuster 330 is moved to the side of the tube 10 fixed to the lower jig 220 and the upper jig 230. [

At this time, the cutter 240 is moved by a set distance (depth) between the layers of the tube 10 to be peeled off.

Particularly, the movement distance of the front and rear slide member 310 and the vertical movement block 320 is set by the cutter advance setting portion 340 by the interlayer separation depth of the tube 10 in the cutter 240.

Here, the cutter advance setting section 340 includes a forward supporter 342 and an advance setting gauge 344. [

The forward supporter 342 is provided in the main body 210 or the lower jig 220. Of course, the forward supporter 342 can be deformed into various shapes.

The forward setting gauge 344 is fixed to the front and rear slide members 310 and presses against the forward supporters 342 when the front and rear slide members 310 are advanced. In particular, the advance setting gauge 344 allows the operator to confirm the forward distance of the front and rear slide members 310. [ This makes it possible to work equally at the distance (depth) at which the cutter 240 is inserted between the layers of all the tubes 10.

Of course, the advance setting gauge 344 is applicable in various ways.

In particular, when the cutter 240 is always exposed, a safety accident may be caused, and the cutter 240 may be damaged.

To prevent this, the up-and-down moving block 320 may be rotatably provided with the cap 500 so as to cover or open the cutter 240. Of course, the cap 500 can be deformed into various shapes.

The upper jig 230 is fixed to the upper and lower slide members 410 and the upper and lower slide members 410 are provided on the main body 210 so as to be slidable in the vertical direction.

The upper jig 230 is fixed to the upper and lower slide members 410 in various ways and the upper and lower movable members can be applied in various shapes. The main body 210 includes an LM guide, Allow up and down movement.

In particular, the upper and lower slide members 410 are raised or lowered in accordance with the rotation direction of the upper and lower shafts 412. The upper and lower shafts 412 are screwed to the upper and lower slide members 410 so that they can be stably and finely adjusted.

The upper and lower shafts 412 have upper and lower handles 414 to facilitate rotation. The operator operates the upper and lower handles 414 to adjust the amount of rotation of the upper and lower shafts 412 so that the upper jig 230 sets the pressing strength to press the tube 10 placed on the lower jig 220. [ Of course, the upper and lower handles 414 can be deformed into various shapes.

The degree of descent of the upper jig 230 and the vertical slide member 410 is determined by the jig height setting unit 420.

Here, the jig height setting unit 420 includes a reference supporter 422 and a check gauge 424.

The reference supporter 422 is provided in the main body 210 or the lower jig 220, and can be modified into various shapes.

The check gauge 424 is provided on the upper jig 230 or the upper and lower slide members 410 until the pressing force of the reference supporter 422 is achieved.

When the check gauge 424 presses the reference supporter 422 to the set value, the upper jig 230 presses the tube 10 placed on the lower jig 220 by the set value, Is disposed in a straight line with the cutter (240).

On the other hand, since the tube 10 has an elastic restoring force, the upper jig 230 is forced to be raised when the pressing external pressure is removed.

To prevent this, a locking portion 430 is provided.

The locking portion 430 serves to prevent arbitrary rotation of the upper and lower shafts 412 and the upper and lower handles 414.

By way of example, locking portion 430 includes latch gear teeth 432 and stopping ribs 434.

The latch gear teeth 432 are formed on the circumferential surface of the upper and lower shafts 412 or on the circumferential surface of the upper and lower handles 414.

The stopping rib 434 is rotatably mounted on the upper and lower slide member 410 or the main body 210 so that the stopping rib 434 is engaged with the latch gear gear 432 after the position of the upper jig 230 is set. Thus, the latch gear gear 432 is arbitrarily prevented from rotating. Of course, when the operator rotates the stopping rib 434 in the opposite direction, the latched gear gear 432 becomes rotatable by arbitrary or external manipulation.

Of course, the stopping ribs 434 can be deformed into various shapes.

As a result, the upper jig 230 presses the tube 10 by the set value through the check gauge 424 and the height of the cutter 240 is adjusted to correspond to the release layer of the tube 10 via the height gauge 334 And is adjusted so that the cutter 240 can be inserted (cut) into the release layer of the tube 10 through the advance setting gauge 344 by a predetermined depth.
