Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, the same technical structures as those of the prior art will be given the same names as they are.

The apparatus for producing a point-to-point tape, in which one side of the present invention is subjected to release (peeling) treatment and two side edges of the release paper are overlapped with each other, and the adhesive is applied to the release surface excluding the overlapping portion, is shown in FIGS. 3 to 5 A pressure-sensitive adhesive supplying unit 100 for supplying the pressure-sensitive adhesive 14 to the surfaces of the release paper 220 and 221 excluding the overlapped portion 230; A release paper supplying unit 200 for supplying the ends of each release paper to the pressure-sensitive adhesive supplying unit 100 while overlapping each other in a state where the pressure-sensitive adhesive 14 is uncoated; A drying unit 300 for drying the peeling paper to which the adhesive is applied and conveyed; A control unit 400 for controlling a transfer speed of the hot air for drying supplied to the drying unit 300 and the release sheets 220 and 221 to be transferred; The release papers 220 and 221 with the adhesive 14 dried in an appropriate state and the adherend 16 supplied from the adherend take-up roll 501 are compressed by a pair of adhering rollers 502, (Not shown).

At this time, the pressure-sensitive adhesive supplying unit 100 for supplying a known liquid pressure-sensitive adhesive (14) having adhesiveness to the heat-sensitive sheet and film to the release paper has an automatic air side 111 for discharging air to the outside, A pressure-sensitive adhesive supply tank 110 in which a flow rate regulating side 112 is mounted on a supply line 113; A pressure-sensitive adhesive inflow part 120 into which the pressure-sensitive adhesive 14 flows from the pressure-sensitive adhesive supply tank 110; A pair of upper and lower pressing rollers 130 and 130 'for flatly pressing the introduced pressure-sensitive adhesive 14 to a uniform thickness within a certain range (40 μm to 70 μm) are formed.

The pressure-sensitive adhesive inflow part 120 mounted to supply the pressure-sensitive adhesive 14 constantly includes a swash plate 121 for allowing the introduced pressure-sensitive adhesive 14 to flow forward; A pair of width adjusting plates 123 for preventing the leakage of the pressure-sensitive adhesive 14 and adjusting the width of the pressure-sensitive adhesive to be applied are formed in the pressure-sensitive adhesive 14 supply box 122 at both ends.

At this time, when the transverse width of the swash plate 121 is 2000 to 2500 mm, the angle? 'Of the swash plate 121 is preferably 22 to 26 degrees as shown in FIG. 3 .

If the angle? 'Of the swash plate 121 is smaller than the upper range, the length of the swash plate in the longitudinal direction is increased and the amount of the stored spots is excessively increased. On the other hand, There is a problem that the pressure-sensitive adhesive is leaked to the outside.

The upper compression roller 130 which adjusts the thickness of the pressure sensitive adhesive (40 μm to 70 μm) is lifted and lowered by an adjustment handle 133 which rotates the height adjusting rod 132 passing through the fixing hole 131, (Amount) of the pressure-sensitive adhesive to be adhered to the paper is adjusted.

In view of the fact that the release paper is the liquid pressure sensitive adhesive 14, the pressure sensitive adhesive press rollers 130 are coated with the pressure sensitive adhesive in a state of being superimposed on the pressure sensitive adhesive rollers 130 and transferred to the transfer tunnel 350, The upward inclination angle alpha of the upper limit angle? Is set to 25 to 30 degrees as shown in FIG.

This is because, when the upward inclination angle is smaller than the upper range, there is a problem that the longitudinal length of the inlet portion of the drying portion becomes longer in the adhesive supply portion. On the other hand, when the upward inclination angle is larger than the upper range, There is a concern that the pressure-sensitive adhesive in the liquid phase flows down at the same time as it becomes larger.

The release agent supplying unit 100 is provided with a superimposed part 230 at the lower part of the adhesive agent supplying part 100 to form a superimposed part 230 in which a part of a plurality of release paper before the application of the adhesive is superimposed, ) Comprises a first release unwinder roll 210 for feeding a first release paper 220; A second release rinse roll 211 for supplying a second release rinse 221; And a marker 240 in the form of a roller for recording product information on the peeled sheets 220 and 221 overlapped with each other.

The drying unit 300 for drying the pressure sensitive adhesive 14 adhered to the release paper comprises a feed mechanism 310 composed of a blowing motor 311, an air supply duct 312 and a plurality of plate type nozzles 313; A gas boiler 320 in which a hot air blower 321 and a burner 322 are mounted to supply the hot air to the air supply unit 310; An exhaust duct 330 for exhausting the introduced air to the outside; An upper rotation cover 340 rotating upward by 60 ° around the rotation pin 341; A plurality of conveying rollers 351 for conveying the peeling paper sheets 220 and 221 in which the overlapped portions 230 are formed are built in the lower end of the conveying tunnel 350 so that a box- A tension roller 352 for retaining the tension of the drive belt 353 for transmitting the power is formed at the central portion of the conveying roller 351.

The arrangement interval of the conveying rollers 351 is 65 to 75 cm in order to prevent shedding of the release paper coated with the pressure-sensitive adhesive.

If the gap between the transport rollers 351 is larger than the upper range, the adhesive tends to leak to the overlapped portion due to sagging. On the contrary, when the gap is smaller than the upper range, the number of transport rollers 351 is increased, And the power ratio rises during maintenance.

The control unit 400 for controlling the conveyance speed and the drying temperature of the release paper includes a speed display unit 410 for displaying a conveyance speed of the release paper 220 and 221, Wow; And a tension controller (420) for controlling a drive belt (353) for rotating a plurality of conveying rollers (351) installed in the conveying tunnel (350).

At this time, the speed display unit 410 includes a work amount display window 411 for displaying a daily accumulated work amount (adhesive tape completion amount); A speed adjusting knob 412 for adjusting the feeding speed; An ON / OFF switch 413 for connecting and disconnecting power; An emergency stop switch 414 for blocking power in an emergency is formed, and the tension controller 420 includes a voltage generator 421 for measuring an input voltage; A power switch 422 and a stop switch 423 for applying and blocking power; And a tension adjusting adjustment knob 424.

A method of manufacturing a point-to-point tape in which a pressure sensitive adhesive (14) is applied all at once on one side of the present invention is characterized in that a part of the first release paper (220) and the second release paper (221) Superimposing and transferring the adhesive to the adhesive supply unit; A pressure applying step of applying a pressure sensitive adhesive (14) to the top of the release paper (220, 221) conveyed from the release paper feeding part; A drying step of supplying dry air to a transfer tunnel (350) through which the release paper (220, 221) coated with an adhesive is passed; The release papers 220 and 221 with the adhesive 14 dried in an appropriate state and the adherend 16 supplied from the adherend take-up roll 501 are compressed by a pair of adhering rollers 502, And a step of winding the film on the substrate.

At this time, the feeding speed of the release paper 220 or 221 is set to 33 to 36 m / min. This is because when the conveying speed is lower than the upper range, the working efficiency is lowered, and at the same time, the adhesion of the release paper to the adherend is lowered due to the solidification of the adhesive due to the high drying. On the contrary, There is a problem that the failure rate of the apparatus is significantly increased.

4, the pressure sensitive adhesive 14 is applied to the lower surface 221 'of the overlapping portion 230 of the release paper 220, 221 in consideration of the convenience of separation of the release paper and the economical use of the pressure sensitive adhesive. .

The humidity of the dry air supplied to the inside of the plurality of conveyance tunnels 350 is set to 25 to 30%, the temperature to be supplied to the first conveyance tunnel 350 is set to 65 ° C, Respectively, so that liquefaction of the pressure-sensitive adhesive 14 due to the initial high temperature is prevented.

3, in order to operate the apparatus for manufacturing point-to-point tapes according to the present invention, first and second peeling ridges 220 and 221 supplied from first and second peeling ridge rollers 210 and 211 So that the overlapping portions 230 are formed.

The first and second release lips 220 and 221 formed with the overlapping portion 230 are conveyed to the adhesive supply portion 100 and pass through between the upper and lower compression rollers 130 and 130 ' And then enters the drying unit 300.

At this time, the width and the thickness of the pressure-sensitive adhesive are adjusted by the pair of width adjusting plates 123 and the upper and lower pressing rollers 130 and 130 '.

The first and second peeled sheets introduced into the drying unit 300 pass through the interior of the conveying tunnel formed under a predetermined condition (appropriate humidity: 25 to 30%, proper temperature: 65 to 85 ° C) (503) and wound on the finished roll (503).

The apparatus and method for manufacturing a spot-on-tape according to the present invention as described above are advantageous in that the cost can be greatly reduced by superimposing low-cost release paper and adhering it to an adherend having a wider width than the release paper.

Further, since the application process is completed by a single adhesive application step, the present invention has the effect of reducing the initial installation cost and drastically reducing the maintenance cost as compared with the prior art having two adhesion processes (main and auxiliary).

The present invention, which is provided with only a pair of width control plates (so-called 'pull cutters') and does not have uncoated portions in the central portion, is provided with two pairs of width control plates to uncoil the center portion, And also has the advantage of preventing the problem that the complex is separated from the product.

(25 to 30) in the conveyance tunnel to prevent the superimposed portion of the release paper from loosening and the conveyance speed (33 to 30 degrees) in the conveyance tunnel so that the liquid pressure-sensitive adhesive applied to the superposed release paper does not flow down, ~ 36m / min) is adopted (control), it is expected that the defect rate can be remarkably reduced.

The present invention, in which the transfer speed of the release paper and the drying of the pressure sensitive adhesive are automatically performed, has the advantage of greatly reducing the number of workers and saving the production cost.

In addition, according to the present invention, since the peeling surface of the overlapping portion is not coated with the pressure sensitive adhesive, it is possible to easily remove the release paper, reduce the consumption amount of the pressure sensitive adhesive, and dramatically reduce environmental pollution.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention.
