5 is a perspective view of a stopper of the cover sheet removing apparatus of FIG.

6 is a left side view of the tape winding part of the cover sheet removing apparatus of FIG.

Referring to Figures 3 to 6, the tape winding portion 20 is provided with an adhesive tape 10 is wound in a roll form. The tape winding unit 20 may include a handle 23 for adjusting the adhesive tape 10, and the adhesive tape 10 used here is the adhesive tape 10 continuously connected to the tape winding unit 20. Since the tape winding unit 20 can be used as a tape winding apparatus that is generally provided, detailed description thereof will be omitted.

The present invention can be applied to remove the cover sheet of the part in the form of a plate with a cover sheet attached to the surface. However, for convenience of description, the operation according to the embodiment of the present invention will be described by taking a case where it is applied to a panel (not shown) to which a cover sheet is attached.

When a panel (not shown) with a cover sheet attached is moved to a lower portion of the cover sheet removing apparatus 1000, the panel is positioned below the horizontal roller 60 to be described below. Meanwhile, the adhesive tape 10 provided from the tape winding unit 20 may include a rotary roller unit 30, a horizontal roller 60, a first conversion roller 80, and a stopper up to the tape collection unit 100 to be described below. 70 is continuously connected to the roller 71 and the second conversion roller (110).

In the present invention, the rotary roller part 30 is composed of three rollers, but is not limited thereto. In addition, a first cylinder 40 is provided at an upper portion of the horizontal roller 60, and a link portion 50 is connected to the lower portion of the first cylinder 40. The first cylinder 40 transmits power to the link portion 50 connected to the lower portion of the first cylinder 40 while moving up and down. The link unit 50 converts the vertical motion of the first cylinder 40 into a horizontal reciprocating motion of the roller guide part 55 located below.

That is, the link 51 of the link unit 50 connected to the lower portion of the first cylinder 40 while the first cylinder 40 moves up and down moves around the hinge shaft 52 and the link unit 50. The roller plate 54 of the roller guide portion 55 connected to the lower portion of the roller guide portion 55 causes the horizontal reciprocating motion along the LM guide 53.

Therefore, the horizontal roller 60 which is connected to the lower portion of the roller plate 54 also has an adhesive tape 10 guided to the lower portion of the horizontal roller 60 while performing horizontal reciprocating motion similarly to the roller plate 54. For example, it can be attached to the panel.

In detail, the horizontal roller 60 is horizontally moved by the link unit 50 described above according to the lowering motion of the first cylinder 40, in which the adhesive tape guided by the rotating roller unit 30 ( 10) moves a predetermined distance while adhering on a predetermined cover sheet (not shown).

At this time, the predetermined distance means the minimum distance that the cover sheet can be peeled off in the adhesive tape 10 is bonded. The horizontal roller 60 starts to adhere the adhesive tape 10 in front of a predetermined distance of one edge of the panel, and moves to the one edge of the panel while adhering the adhesive tape 10.

Then, the horizontal roller 60 is returned to its original position according to the upward movement of the first cylinder 40. In this process, the adhesive tape 10 attached to the cover sheet has the adhesive force of the adhesive tape 10. The cover sheet is separated from the panel by the.

On the other hand, after the horizontal roller 60 returns to the original position, the stopper 70 holds the adhesive tape 10 by the second cylinder 90 to move upward by a predetermined length.

Specifically, the second cylinder 90 includes an upper and lower cylinder 91 for lifting and lowering motion and a horizontal cylinder 92 for horizontal motion.

On the other hand, the stopper 70 is composed of a plurality of stopper rollers 71, fixed clamp 73 and the moving clamp (75). In the figure, the fixed clamp 73 and the movable clamp 75 are shown separately, but are actually coupled through a bracket.

As mentioned above, when the horizontal roller 60 returns to its original position, the stopper 70 is moved by the horizontal clamp 92 of the second cylinder 90 located on the left side. Approach to 73) to hold the adhesive tape 10 between the fixed clamp 73 and the movable clamp 75, the upper cylinder 91 of the second cylinder 90 is moved to the upper direction, is coupled thereto The stopper 70 is also moved upward while holding the adhesive tape 10.

After the stopper 70 moves upwards, when the movable clamp 75 returns to its original position by the horizontal cylinder 92 of the second cylinder 90, that is, the movable clamp 75 is fixed clamp ( 73, the holding adhesive tape 10 is held apart from the holding state, and the stopper 70 is also lowered by the lowering of the upper and lower cylinders 91 of the second cylinder 90, and the original position is lowered. Return to The stopper roller part 71 performs a function of preventing the fixed clamp 73 from sticking to the adhesive surface of the adhesive tape 10 when the stopper 70 is lowered so as not to interfere with the lowering of the stopper 70. do.

In addition, the adhesive tape 10 attached to the cover sheet by the horizontal roller 60 is loosened as the horizontal roller 60 returns to its original position, and the first shifting roller 80 moves in the adhesive tape 10. Is switched while having a tension in the movement direction of the stopper 70, the adhesive tape 10 is moved upward by the stopper 70. The first conversion roller 80 is installed at one end of the LM guide 53 so that the adhesive tape 10 can maintain the tension, in particular the first conversion roller 80 is horizontal roller 60 so as not to contact the cover sheet. Install a little higher than).

On the other hand, the second cylinder 90 to move up and down and horizontal to control the stopper 70 is installed on the left side of the movable clamp 75, as described above, is coupled with the stopper 70.

The adhesive tape 10 guided from the stopper 70 is collected by the tape collecting part 100. At this time, it may be provided with another second conversion roller 110 to maintain the tension of the adhesive tape 10 and to change the moving direction of the adhesive tape 10 between the stopper 70 and the tape collection unit 100. .

As described above, optimal embodiments have been disclosed in the drawings and the specification. Although specific terms have been used herein, they are used only for the purpose of describing the present invention and are not intended to limit the scope of the invention as defined in the claims or the claims. Therefore, those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

As described above, the apparatus for removing a cover sheet according to the present invention can automatically remove the cover sheet without being limited to the size of the panel and the length of the cover sheet to be removed. It has the advantage of lowering speed and improving working speed.
