Description

METHODO FOR BONDING PAPER TO SHEET OR FILM

The present invention relates to a method of adhering paper to a sheet or a film, and more particularly, to a wide sheet (1680-2500mm) when fabricating a hot mat, an electric mat, a noise preventing sheet, an interior film, or the like. The present invention relates to a method of adhering paper to a sheet or a film capable of easily adhering paper to a film.

In general, the electric mat or hot water mat used in the winter is a heating mat that is popular in the popular use in that it can reduce the heating cost by locally heating the floor of the room.

These heating mats are seated on the surface to protect the cushion function and interior.

By the way, the sheet should be adhesive, so that one side of the sheet should be provided with a silicon adhesive as a certain thickness, for this purpose, the adhesive is applied to the paper with a protective paper of the same width, and the adhesive coated surface When laminated to one side of the sheet was prepared in such a way that the adhesive layer is naturally formed on one side of the sheet while the adhesive layer is protected by the paper, and in use, the paper was removed.

However, since the width that can be adhered at one time with a conventional adhesive is limited to 1680 mm, the recently released wide sheet has a disadvantage that it is very cumbersome and difficult to adhere the adhesive.

In other words, 1680mm width was enough because single or double mats were mainly used, but as living room culture spread, 1680mm or more wide mats for 4-6 people, such as width 1800-2500mm and length 2400 There is a need for a wide mat with -4000mm.

Therefore, when the sheet was used, two sheets having a width of 1680 mm having an adhesive layer formed thereon were prepared with one sheet first, and then the remaining sheet was horizontally padded and used as the remaining width.

For example, when the mat was 2400mm wide, 1680mm was placed first, and then the remaining sheets were placed horizontally to secure 720mm, and then the remaining 960mm was used as a form of cutting.

As a result, the workmanship is increased, the material loss is large, the cost is increased, and the materials must be arranged horizontally, so that defects such as surface flatness mismatches and gaps are generated in the connected areas.

This problem is not only a silk mat, but also a problem that occurs in the noise-proof film or interior sheet having an adhesive layer.

The present invention was created in view of the above-mentioned problems in the prior art as described above, and it is possible to easily and conveniently form a pressure-sensitive adhesive layer on a wide sheet in one operation to reduce manufacturing costs and improve productivity while also reducing material loss. Its main purpose is to provide a method of adhering paper to a sheet or film that can be reduced.

At this time, after the pressure-sensitive adhesive coating process, the pressure-sensitive adhesive applied to the upper surface of the main paper or auxiliary paper passing through the guide unit is further carried out by a drying process to maintain a semi-dried state uniformly by section by a plurality of warm air fans It has its features.

In addition, in the lamination process, the pressure-sensitive adhesive applied to the secondary paper laminated in the form of a part overlapping the lower surface of the main paper to be semi-dry through a separate hot air to maintain the same dry state as the pressure-sensitive adhesive applied to the main paper at the time of lamination It also has its characteristics.

According to the present invention, it is possible to easily and conveniently form an adhesive layer on a wide sheet in one operation, thereby lowering manufacturing costs and improving productivity, thereby reducing material loss.

2 is a conceptual schematic view showing a lamination example for explaining the method according to the present invention.
3 and 4 are conceptual schematics showing an embodiment of lamination by the method according to the present invention.

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

In the method of adhering paper to a sheet or film according to the present invention, a pressure-sensitive adhesive coating process for applying an adhesive to one side of a protective paper, a lamination process for laminating a protective paper coated with pressure-sensitive adhesive to have a desired width, and a laminated paper It consists of an attachment process which adheres to a material, ie, a to-be-adhered body, and is comprised so that these processes may be processed continuously.

Here, the laminating step may further include a drying step of drying to a certain degree so that the applied pressure-sensitive adhesive is adhered to the adherend (sheet or film) smoothly to a semi-dry state.

To this end, the present invention, as shown in Figures 1 and 2, in terms of equipment, the guide unit 100, a plurality of support rolls 110 and the first and second tension rolls (120, 122), and the first and second Adhesives 200, 210, first and second unwinding rolls (300, 310), adherend unwinding rolls 320, adherend winding rolls (Winding Roll) 400, a plurality of hot air heaters 500, proximity sensor 600 ) And a thermal sensor 700.

At this time, the guide unit 100 is a hollow cylinder inside, is formed in a curved curve in the longitudinal direction, one side is branched to form a mouth side, the first side and the second winding rolls (300, 310) are respectively disposed The first and second winding rolls 300 and 310 are wound around the main paper M and the auxiliary paper S, respectively.

In addition, a plurality of support rolls 110 are installed in the guide unit 100 at regular intervals so as to support the main paper M and the auxiliary paper S in rotation, and the guide unit 100. A plurality of warm air heaters 500 are installed at a predetermined interval on the upper side of the upper part, and a warm air fan 500 is also installed above the branched mouth portion of the guide unit 100 to be released from the first and second winding rolls 300 and 310. The pressure-sensitive adhesive applied to the resulting paper is dried to a semi-dry state.

In addition, the first and second adhesives capable of applying an adhesive on the upper surface of the paper, ie, the main paper (M) and the auxiliary paper (S), released from the upper side of the first and second winding rolls (300, 310). 200 and 210 are respectively installed.

In addition, in order to automatically adjust the driving of the hot air heater 500, the heat detection sensor 700 that can measure the temperature for each section at regular intervals is installed in various places of the guide unit 100, in particular, the main paper (M). ) And the auxiliary paper (S) is laminated so that the proximity sensor 600 is installed to check the presence of proximity and to detect the processing failure in advance to control the operation.

In addition, in the present invention, the control method itself is not only characterized, and such control is well known, and thus, a detailed description of the control flow or procedure using the proximity sensor 600 is omitted here.

However, by adjusting the tension of the first and second tension rolls 120 and 122, which will be described later, based on the signal value detected by the proximity sensor 600 in the lamination process, it is possible to control the position where the paper is wound. Only the degree will be briefly described.

In addition, a first tension roll 120 is installed at the exit side of the guide unit 100 to guide the adhesive unit 330 to be attached to the adherend 330 while maintaining an appropriate tension on a paper coated with a pressure-sensitive adhesive. At the position opposite to the tension roll 120, a second tension roll 122 is installed to guide the adherend 330 released from the adherend winding roll 320 to the adherent winding roll 400 while supporting the adherend 330 at an appropriate tension. do.

According to the present invention having such an apparatus configuration, the sheet or film can be adhered in a wide manner in the following manner.

First, an adhesive applying process is performed.

In the pressure-sensitive adhesive coating process, the pressure-sensitive adhesive is uniformly coated on the upper surface of the main paper M released from the first winding roll 300 through the first adhesive 200, as well as released through the second winding roll 310. It includes both the process of uniformly applying the pressure-sensitive adhesive through the second adhesive 210 on the upper surface of the auxiliary paper (S).

In this case, the most important point is that the main paper (M) should always be moved ahead of the auxiliary paper (S) beforehand, preferably, it should be preceded first by the distance from the entrance side to the branched point, that is, the point where the paper occurs. will be.

This is not only because it takes time to adjust the amount of overlap to fit the width, but also the starting point from which these papers are released, and the main paper (M) is the base size, that is, the base with a width of 1680mm. This is because the auxiliary paper (S) is the sub to be added thereto.

Subsequently, a lamination process is performed.

The lamination process is a process of attaching the unfolded main paper (M) and the auxiliary paper (S) to each other to have a wide width, that is, 1680 mm or more and a width of 2500 mm or less. Secondary paper (S) on the opposite side as shown in Fig. 3 is placed in a partially overlapped state refers to a process that two papers are attached to one paper.

In this case, since the paper itself has nothing on the back side of the main paper (M), when the adhesive surface of the auxiliary paper (S) is attached to it, when the state of this state is viewed as a longitudinal cross section, in the overlapped portion, the adhesive layer-paper-adhesive layer-paper In the form of a non-overlapping place, only the adhesive layer-paper form appears.

Therefore, when the adhesive is attached to the width of the adherend 330 later and then cut off during use, the adhesive adhered to the back side of the main paper (M) falls neatly as if cut in an inline state based on the overlapping boundary. The sheet is constructed as if it were a single width with few gaps.

In addition, while the lamination process is in progress, the drying process as described above is carried out together to maintain the pressure-sensitive adhesive in a semi-dry state to further improve the adhesion to the adherend 330. In this case, temperature control required for drying is enabled by controlling the driving of the warm air fan 500 by the section by the heat detected by the heat sensor 700.

Particularly, in the drying process, the pressure-sensitive adhesive applied to the auxiliary paper laminated in the form of a portion overlapping the lower surface of the main paper is semi-dried through a separate warm air heater and a heat sensor to dry the same as the pressure-sensitive adhesive applied to the main paper at the time of lamination. It is very important to maintain the condition, which allows the same drying conditions to be met in a short time, although the auxiliary paper is followed, minimizing the occurrence of defects.

Thereafter, the attaching process is performed.

The attaching process is a process of attaching a paper having an adhesive surface which becomes one paper through the lamination process to one surface of the adherend 330 to form an adhesive layer.

In this process, the adhesive surface of the laminated paper whose tension is maintained by the first tension roll 120 is opposed to one side of the adherend 330 which is moved while the tension is maintained by the second tension roll 122. It is made in the form of being attached to each other by the adhesive force of the pressure-sensitive adhesive while being moved in the dark state.

At this time, the adherend 330 is released from the adherend winding roll 320 and wound onto the adherent winding roll 400, and the attachment is made in the middle, and is wound in the attached state.

The sheet having the pressure-sensitive adhesive layer thus wound may be further subjected to a separate cutting process to be cut to a required width afterwards, or may be further provided with a cutting process following the attaching process, and then wound into a state that is cut to fit the production width and then commercialized. Of course.

In addition, as shown in FIG. 4, the surface to which the pressure-sensitive adhesive is applied may be formed as opposed to the example of FIG. 3, and although not shown, the main paper may be controlled through the control of the proximity sensor 600 and the first and second tension rolls 120 and 122. (M) and the auxiliary paper (S) can be made by directly horizontally and parallel as in the conventional example without overlapping each other, because this is possible because the control using the sensor and tension as described. However, the present invention does not disclose the structure of the device in detail, but the claims are not claimed in the scope of rights, but it is clear that the technology is not at all feasible.

As described above, the method according to the present invention is expected to greatly improve its utility since it is possible to make a wide sheet very conveniently and easily.
