Description

[0001] WIDE BONDING DEVICE FOR SHEET OR FILM [0002]

More particularly, the present invention relates to a wide adhesive apparatus for a sheet or a film, and more particularly, to a wide adhesive apparatus for a sheet or a film, To a wide adhesive apparatus for sheet or film.

In general, electric mats or hot water mats used in the winter season are heating mats in which popular use is common in that the heating cost can be reduced by locally heating the floor of the room.

These heating mats are covered with sheets to protect the cushioning function and the interior.

However, since the sheet must have adhesiveness, the silicone should be coated on one side of the sheet to a certain thickness. For this purpose, in general, the protective paper (the release paper, silicone is coated on one side) When the adhesive is applied on the silicon and then bonded to one side of the sheet, the sheet can be protected while being adhered to the sheet. In use, when the release sheet is removed, silicone is transferred to the sheet together with the adhesive to form an adhesive surface on one side of the sheet .

However, in spite of the fact that the conventional releasing paper can be manufactured to have a sufficiently wide width, the maximum size of the paper in which the silicone can be applied is 1680 mm, so that the width of the releasing paper coated with silicone is limited to 1680 mm.

Therefore, it is difficult to make a wide sheet exceeding 1680 mm at a time in the case of a wide sheet which is recently released.

In other words, since a single person or a two-person mattress was mainly used, a width of 1680 mm was sufficient. However, as the living culture spreads, a wide mattress of 1680 mm or more corresponding to 4-6 persons, such as a width of 1800-2500 mm, A wide-width mat having a width of -4000 mm is required.

Thus, in order to make a wide mat, two sheets having a width of 1680 mm in which an adhesive layer (= silicon) is formed are prepared, one sheet is arranged first, and the other sheet is horizontally stacked by the remaining width to secure a desired width And then the remaining portion was cut out and pasted to form a wide-width mat.

For example, in the case of a mat having a width of 2400 mm, a sheet of 1680 mm is first placed to prepare a sheet suitable for the mat, and then the other sheet is horizontally arranged to secure 720 mm, and then the remaining 960 mm is cut A sheet having a width of 2400 mm can be made, and a wide-width mat having a width of 2400 mm can be manufactured.

For this reason, the production of the wide width sheet in the related art requires a large work loss, a large material loss, a high cost, and a horizontally arranged material, so that not only a defect in surface flatness but also a gap Defects were also observed.

Such a problem does not only correspond to a mat, but also to a noise-preventing film having an adhesive layer and an interior sheet.

To solve this problem, the present applicant has developed a technique capable of wider adhesion, and has been patented in Registration No. 1176872 (Aug. 20, 2012).

However, since the above-mentioned patent technology has been applied for a long period of time, the following improvements have been found, and a need for supplementary patents has arisen.

For example, in the registered technology, the adhesive liquid is applied to the main paper (main release paper) coated with silicone, and the adhesive liquid is separately applied to the auxiliary paper (auxiliary release paper). Subsequently, As a result, in the overlapping portion of about 20-150 mm overlapping, the lower surface of one side of the main paper having no adhesive liquid and the side surface of one side of the auxiliary paper on which the adhesive liquid is deposited meet locally, A section in which the adhesive liquid is not partially adhered is generated in the range of 1 to 3 mm, so that a floating phenomenon occurs when the adherend is adhered, which leads to a product defect.

In addition, due to the necessity of installing each adhesive separately, the cost and space restrictions were also followed.

In addition, when the main paper and the auxiliary paper are moved while being supported by the simple guide roll, there arises a problem that the overlapped portions are spread due to unevenness of tension during transportation, causing unevenness in width, resulting in product defects.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in the prior art, and it is an object of the present invention to provide an adhesive layer on a wide sheet easily and conveniently by a single operation, The present invention provides a wide adhesive apparatus for a sheet or film.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic process diagram showing an adhesion method using a pressure-sensitive adhesive apparatus according to the present invention.
2 is an exemplary plan schematic view of a portion of the process of FIG.
FIG. 3 is an excerpt of a part of a characteristic part for implementing the adhesive apparatus according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

The wider adhesion method for a sheet or film according to the present invention is a wiping method for applying a sticky solution on one side (a surface coated with silicone) of a protective paper, that is, a release paper, ), And these processes are configured to be continuously processed.

Here, a drying process may be further included to dry the adhesive to a certain extent so that the adhesive applied before the application process after the adhesive liquid application step adheres to the adherend well, thereby achieving a semi-dry state.

To this end, the present invention comprises a tacking device, as shown in Figures 1 and 2.

The adhesive apparatus includes a main unwinding roll (100).

The main take-up roll 100 is a roll on which the main release liner 110 is wound and is wound around the shaft R1 so that the main release lane 110 is loosened and meandered, A disc-shaped main guide flange 120 larger than the roll radius of the main take-up roll 110 is removably screwed.

In addition, the sub-take-out roll 200 is installed in a state in which the main take-up roll 100 is partially overlapped with the main take-up roll 100 at left and right intervals.

The sub-roll release 200 is a roll on which the sub-release liner 210 is wound and releases the sub-release liner 210 with a predetermined tension. The sub-release liner 210 is wound on both ends of the shaft R2 so as not to meander, A sub-guide flange 220 in the form of a disk larger than the roll radius of the sub-outlet roll 210 is releasably screwed.

The main release paper 110 and the sub-release paper 210 are fed while being superimposed in a part of a width, for example, 20-150 mm.

At this time, the conveyed length in the overlapped state is about 24 m, and many, preferably five, dryers 300 are provided in the section.

The dryer 300 includes first, second, third, fourth, and fifth dryers 300a, 300b, 300c, 300d, and 300e, each having a size of about 4 m.

The dryer (300) dries the adhesive liquid in a semi-dry state, and by using a plurality of dryers, it is gradually and gradually dried in a continuous mode instead of a continuous mode, thereby solving problems such as non- And a uniform drying effect can be obtained over the entire surface.

In addition, the main release paper 110 and the sub-release paper 210 may be supported by the tension roll 400 so as to maintain a constant tensile force, And the sub-release papers 210 enter the lower portion of the main release papers 110.

In this case, the tension roll 400 is provided as a spring roll. The tension roll 400 includes a fixed body 410, a movable body 420 that is assembled with the fixed body 410 and elastically flows the moving body 420, At least one spring 430 embedded in the fixing body 410 and a roll 440 rotatably fixed to the moving body 420.

Accordingly, the tension roller 400 can move the movable body 420 with respect to the fixed body 410 due to the elastic action of the spring 430 according to the change of the tension, And uniform support is possible, so that the meandering of the sub-releasing paper 210 is minimized.

In addition, an adhesive nozzle 500 having a variable width is installed above the space main release film 110 between the tension roll 400 and the first dryer 300a.

The adhesive nozzle 500 is installed only one time so that the main release paper 110 and the sub-release paper 210 can be adhered to each other over the entire width in a state where the main release paper 110 and the sub-release paper 210 are overlapped. That is, the adhesive nozzle 500 is a means (coater) for coating the adhesive liquid on the silicon coated on the release paper (main and sub), and the width thereof can be controlled by design.

That is, since the main release paper 110 and the sub-release paper 210 can be manufactured only at a width of 1680 mm or less due to the silicon to be coated, the adhesive nozzle 500 is a viscous solution coating apparatus irrespective of silicone application. It is possible to make it as long as possible, preferably 2500 mm. Of course, more than that is possible.

In particular, as shown in the figure, the adhesive nozzle 500 has a circular space S at its lower end and an adjusting screw 510 screwed into the space S, and the adjusting screw 510 has a handle 520 are installed to allow the adhesive liquid supplied through the adhesive liquid supply port 530 to be discharged downward only within the width adjusted by the adjustment screw 510, Variable is possible.

In other words, when the adjusting screw 510 is deeply inserted, the adhesive solution coating width can be narrowed, and when the adjusting screw 510 is loosened and removed, the adhesive solution coating width can be widened.

Therefore, in the present invention, unlike the conventional method, the main release paper 110 and the sub-release paper 210 overlap each other using only one pressure-sensitive adhesive nozzle 500, It is possible to uniformly coat the adhesive solution on the entire surface without forming an uncoated portion, so that adherends are not lifted when the adherend is adhered, so that a high-quality product can be produced.

In addition, the adhesion nozzle 500 may be configured to be adjustable in height by using the up-down cylinder 540 and the proximity sensor 550 installed at the tip of the nozzle.

This is useful for varying the thickness of the adhesive liquid to be coated, and the proximity sensor 550 detects and automatically controls the falling height of the ascending / descending cylinder 540 within a predetermined interval, Can be automatically controlled by using a controller such as a microcomputer.

Meanwhile, a plurality of guide rolls 310 are installed in the dryer 300.

The guide roll 310 is a means for guiding and guiding the main release sheet 110 and the sub-release sheets 210 conveyed in the overlapped state in a rolling contact manner at the bottom.

However, in the conventional case, since the single roll type single roll structure is used, a meander occurs due to non-uniformity of tension, and a problem arises that a portion where the main release paper 110 and the sub-release paper 210 overlap each other occurs. Therefore, The structure of the roll 310 is improved to a unique form.

For example, as shown in FIG. 3A, the enlarged diameter portion 320 is formed at one end of the guide roll 310, preferably at one edge portion of the sub-separable paper 210.

The diameter of the guide roll 310 is larger than the diameter of the guide roll 310. The boundary between the guide roll 310 and the diameter portion 320 is perpendicular to the guide roll 310, And one end of the guide member 210 may be used in a state in which the guide member 210 is disposed in a state of being bent while being slightly bent.

In this case, since the force is pulled downward at the curved portion, the sub-releasing paper 210 does not deviate from the curved portion of the sub-releasing paper 210 and can be prevented from spreading out.

3 (a), the enlarged portion 320 may be formed to have a slope 330 so as to naturally follow the boundary as shown in FIG. 3 (b) It is possible.

In this way, when the slope 330 is formed, the sub-release paper 210 is smoothly and smoothly warped, so that even more stable transfer can be achieved while preventing the overlapped portion from spreading due to prevention of warpage.

In addition, a separate bracket is fixed to the roll axis of the guide roll 310, and a sensor member such as a limit switch or a proximity sensor is further provided to immediately detect the sub-release sheet 210 when it separates from the guide roll 310 It is also possible to have a double safety detection structure by configuring the equipment so that it can be restarted after calibration.

The upper pinch roll 600 and the lower pinch roll 610 can be rotated to abut against the lower end of the dryer 300. The overlapped releasing paper passes through the upper pinch roll 600 and the lower pinch roll 610.

A rolled product roll 700 is provided on one side of the upper pinch roll 600 and a lower pinch roll 610 and a product roll 800 is provided on the other side of the upper pinch roll 600 and the lower pinch roll 610, The adhered material 710 unwound from the roll 700 is put into a space between the upper pinch roll 600 and the lower pinch roll 610 and is mixed with the overlapped releasing paper and discharged therefrom. As shown in Fig.

The present invention having such an apparatus configuration can adhere a sheet or a film to a wide width in the following manner.

First, the adhesive liquid application step is performed.

Unlike the conventional method, the adhesive application step forms the overlapped part before the adhesive solution is coated.

That is, the main release paper 110 and the sub-release paper 210 unwound from the main take-up roll 100 and the sub-take-out roll 200 are wound on a tension roll 400 having a spring roll shape, And a coating process in which the adhesive liquid is applied to the surface of the release paper overlapped while simultaneously being loosened while being overlapped with each other with the adhesive nozzle 500 at one time.

At this time, the most important point is that the main release paper 110 and the sub-release paper 210 must be overlapped before applying the adhesive liquid, and simultaneously move in the overlapped state.

Therefore, there is no need to provide an additional facility for applying a different adhesive liquid, and it is advantageous to save cost, time, and space because it is not necessary to provide a double coating, and in particular, It is a point.

Particularly, since the overlapped portion is already formed and maintained in a laminated state during the adhesive liquid application process, a separate laminating process is not separately required in the present invention.

In addition, since the sheet according to the present invention is not so long as several hundred meters, even if the sheet is wound in the overlapped state, there is no defect due to the overlapped portion at the time of winding. Therefore, it is possible to omit a lot of steps that have been carried out until the product is wound up as compared with the prior art.

The drying process is performed while passing the plurality of dryers 300 in a state in which the adhesive liquid is applied. In the drying process, a plurality of dryers 300 are separated from each other, and stepwise drying is performed intermittently Thereby maintaining a uniform semi-dry state and improving adhesion to the adherend 710.

In this case, temperature control required for drying can be automatically controlled using a heat sensor and a hot air fan.

Then, an attaching process is performed.

In the adhering process, the two release papers are superimposed on each other to be changed into one release paper, and the adhesive is transferred onto one surface of the adherend 710 while having an adhesive layer on one side.

This process is performed in a state in which the adhered surface of the bonded release paper sheet maintained in tension by the upper pinch roll 600 is brought into contact with one side of the adherend 710 to be moved while being held in tension by the lower pinch roll 610 And adhere to each other due to the adhesive force of the adhesive.

At this time, the adherend 710 is released from the rolled-up roll 700 and rolled to the product take-up roll 800, where the adhering is made, and the rolled product is rolled into an adhered state.
