At this time, the space portion 11 is preferably a rectangular space structure, the inlet 12 is disposed on the right rear of the space portion 11, the outlet 13 is the left side of the space portion 11 It is placed in front. This arrangement is only an example, and will be deformable and changeable.

The tape fabric (1) in the space 11 of the drying chamber 10 in the state where the adhesive is applied to one surface (hereinafter referred to as'coating surface') of the tape fabric 1 by the coater 20 ) Is transferred, the hot air or the like is supplied so that the adhesive liquid is dried and cured. At this time, hot air is supplied by a hot air fan or high-temperature steam is supplied by a gas boiler.

The coater 20 is

3 and 4,

For coating by applying an adhesive to one surface of the tape fabric (1) disposed and supplied to the inlet 12 of the drying chamber 10,

The nozzle opening is opened by an external control in the chamber in which the adhesive solution is accommodated, and the adhesive solution is sprayed from the nozzle opening opened in this way to be made of a conventional coating device that can be evenly applied to one surface of the tape fabric 1 being transported. .

The transfer guide unit 30 is

The tape fabric 1 disposed in the space 11 of the drying chamber 10 and coated with an adhesive by the coater 20 is dried from the inlet 12 of the drying chamber 10 to the drying chamber 10. ) To guide to have a transport section repeated left and right until reaching the exit (13),

1 to 5, the transfer section of the first embodiment is formed in a'W' shape. Eventually, after the tape fabric 1 entering the inlet 12 of the drying chamber 10 moves inclined to the left, it changes direction and moves inclined to the right again, and moves inclined to the left again by changing direction. It forms a section structure in which the operation is repeated.

As shown in FIG. 6, the transfer section of the second embodiment is formed in a form in which'′' is laid at 90 degrees. Eventually, the tape fabric 1 entering the inlet 12 of the drying chamber 10 moves horizontally from the inlet 12 to the left, and then moves by changing the direction in the 90 degree direction, and again changing the direction in the 90 degree direction. By forming a section structure in which a series of motions moving horizontally to the right are repeated.

The transfer guide unit 30 having a transfer section of the first and second embodiments made of the above structure is

As shown in Figure 4,

The tape fabric (1) along each transfer roller 31 in a state where the non-coated other surface of the tape fabric 1 (hereinafter referred to as a'non-coated surface') is wound on each transfer roller 31 Drive means for transferring)

Is made of

4 and 5, in the transfer guide unit 30 having a transfer section of the first embodiment, the driving means 32 is a first shaft 321 that is axially coupled to the transfer rollers 31 disposed on the left side. And, a second shaft 322 that is axially coupled to the transfer rollers 31 disposed on the right side, a first driving unit 323 for transmitting rotational power to the first shaft 321, and the second shaft ( 322) is composed of a second driving unit 324 for transmitting rotational power.

At this time, it is possible to transfer the tape fabric 1 with only one of the first driving part 323 or the second driving part 324, and at this time, the transport rollers 31 that do not receive power are idle rollers, that is, free It is desirable to form a rotating roller structure.

In addition, without transmitting power to the first shaft 321 and the second shaft 322, separate forcing interlocked with each other outside the inlet 12 or the outlet 13 of the drying chamber 10, or both. After placing the transfer roller, by transmitting rotational power in a direction interlocked with the forced transfer roller to rotate, the tape fabric 1 may be implemented for transfer.

In addition, each of the drive units 323 and 324 is a drive motor, and the drive shaft and the shaft of the drive motor are interconnected by a belt or the like so that the shaft can rotate when the drive shaft of the drive motor rotates.

As shown in FIG. 6, in the transfer guide unit 30 having the transfer section of the second embodiment, the driving means 32 may transmit rotational power to one or more of the shafts axially coupled to each transfer roller 31. In consideration of the cost aspect, after placing the separate forced transfer rollers engaged with each other outside the inlet 12 and the outlet 13 of the drying chamber 10, the rotational power is transmitted to the forced transfer rollers in a direction interlocked with each other. It can be made of a rotating structure.

And, as shown in Figure 5, each of the transport rollers 31 is provided with an annular stopper 311 that protrudes along the outer circumferential surface of both ends to limit the lateral movement of the tape fabric 1, the tape fabric 1 ) As the both ends of the tape fabric 1 are transported in the state arranged in the stopper 311 during transport, the tape is transported stably without departing from the transport roller 31.

On the other hand, as shown in Figure 7, the transfer guide unit 30 is

Among the transport rollers 31, the spacer 11 of the drying chamber 10 is arranged between the transport roller 31 disposed adjacent to one inner wall and the transport roller 31 disposed adjacent to the other inner wall, and is taped. The non-coated other surface of the fabric 1, that is, located on the upper side of the non-coated surface 1b, is wound between two transport rollers 31 to reduce the motion of the tape fabric 1 drooped by its own weight moving up and down during transport. For preventing the rolling roller 33 is further provided.

At this time, the rolling prevention roller 33 may be implemented to allow height adjustment up and down by a separate lifting device or the like.

When the tape fabric 1 is forcibly transported by a roller or the like rotated by a driving unit, the tape fabric 1 is struck downward between the transport rollers, and at this time, the coated surface of the tape fabric 1 when transported in the struck state ( The adhesive liquid applied to 1a) may not flow down or evenly distributed before being cured, and may be problematic in that the adhesive liquid is not coated properly while being crushed to one side to form a rugged surface. At this time, the rolling prevention roller 33 Since the upper side of the sagging tape fabric 1 is disposed adjacent to the non-coated surface 1b side, the tape fabric 1 is prevented from rolling up and down, such as shaking up and down, when transporting, thereby sticking It is possible to obtain a good-quality coated surface that is cured by evenly distributing the liquid.

On the other hand, among the transport rollers 31, the transport rollers 31 arranged on the upper side or the transport rollers 31 arranged on the lower side, or both, are moved back and forth based on the rotation center of the transport roller 31. It is also possible to implement the tilt, that is, to adjust the angle. In order to adjust the angle, a transport roller is provided by providing a separate support member for supporting the transport roller 31 to be rotated, a rotation shaft coupled to the lower part thereof, and a driving motor that provides power for forward or reverse rotation of the rotation shaft. 31) can be adjusted before and after tilt.

On the other hand, the present invention further moves the displacement means (40) for adjusting the gap between the conveying rollers 31 facing each other by moving in opposite directions and opposite directions to each conveying roller 31 Including,

The displacement means 40

7 to 10,

Elm Block (41),

A pillar body (42) coupled to the EL block (41), capable of moving back and forth along the EL block (41) and supporting the shaft of the transfer roller (31),

A housing 43 installed on the sidewall of the LB block 41 and having a receiving portion 431 inside one side,

Plate 44 is coupled to cover the opening side of the receiving portion 431 of the housing 43,

A pair of fitting holes 45 penetrated in and out of the plate 44,

C-shaped elastic clamp 46, both ends of which are fitted into each of the fitting holes 45 to be exposed toward the receiving portion 431 and the middle end toward the pillar body 42 side,

Adjusting bolts (47) fastened to both ends of the elastic clamp (46)

Is made of

At this time, when the tension adjustment for the tape fabric 1 is required, when the adjustment bolt 47 is tightened, as shown in FIG. 9, both ends of the elastic clamp 46 are close to each other, so that the middle end is the pillar body 42. By moving to the side, the pillar body 42 is moved along the EL block 41.

In order to prevent the column body 42 moved in this way from being moved further in the moving direction, as shown in FIG. 10, a support body connected to the column body 42 and disposed on the upper side of the LB block 41 ( 48) is provided with a fixing bolt 49 that is fastened to the support 48 so that an end thereof presses the upper surface of the LB block 41. As a result, the elastic clamp 46 elastically supports the pillar body 42 while the movement of the pillar body 42 is restricted by the fastening operation of the fixing bolt 49.

After all, when displacement (變位) with respect to the pillar body (42) is required, release the fixing bolt (49) to release the pressure on the upper surface of the L-block (41) and then adjust the adjusting bolt (47). This is made possible by tightening or loosening.

In the existing drying system, the length of the device including the drying section reaches approximately 30 meters, and its weight is considerable, as the drying section is realized in a long straight line, and it is necessary to secure a space in which such equipment can be installed. And its installation cost is also considerable,

The conveying device (MS) of the present invention made up of the above configuration realizes an alternating drying section, so that the length of the existing preparation device can be greatly reduced to about 4 meters, thereby minimizing the installation space. I can expect.

Meanwhile, as shown in FIGS. 11 and 12, the heating sheet 50 is

The protective layer 52, the thermal diffusion coating layer 53, and the copper plate 54 are sequentially stacked, and the planar heating element 51 is interposed between the protective layer 52 and the thermal diffusion coating layer 53 to be interposed. Is done.

Here, the protective layer 52 functions to protect the planar heating element 51 from the outside while having an insulating function.

In addition, the heat diffusion coating layer 53 helps the heat generated by the planar heating element 51 to diffuse more easily and be transferred to the one surface of the tape fabric 1 through the copper plate 54. The thermal diffusion coating layer 53 may be formed of a material such as graphite, which is formed by processing carbon and has a plate-like structure and excellent horizontal thermal conductivity.

In addition, the copper plate 54 is a medium having high thermal conductivity, and the temperature of the heat generated through the copper plate 54 is about 150 to 250 degrees.

13 and 14, the planar heating element 51 preferably has a width corresponding to each other with the tape fabric 1, and also between various rollers 2 for guiding the transfer of the tape fabric 1 It is preferable to have an appropriate length to match the separation distance between two adjacent rollers 2 in the state in which the heating sheet 50 is disposed between them. That is, the heating sheet 50 is to include a single planar heating element 51 having a length suitable for the separation distance between two adjacent rollers 2.

Or, as shown in Figure 15, the planar heating element 51 is provided with a plurality, is disposed at regular intervals between the protective layer 52 and the thermal diffusion coating layer 53, a number of planar heating elements 51 are arranged in this way It is preferable that the heat generating sheet 50 has an appropriate length to match the distance between two adjacent rollers 2 for guiding the transfer of the tape fabric 1. That is, the heating sheet 50 is to include a plurality of planar heating elements 51 which are arranged at regular intervals to match the distance between two adjacent rollers 2.

Alternatively, as shown in FIG. 16, the heat generating sheets 50 may be provided to be arranged at regular intervals between two adjacent rollers 2. At this time, for each heating sheet 50, a power supply unit 60 for power supply and control may be provided individually, or power supply and control may be integrated through one power supply unit 60.

On the other hand, the protective layer 52 is configured to cover the entire surface of the opposite surface facing the one surface of the tape fabric 1 in the heating layer 511, which will be described later, that is, the entire surface, thereby protecting the upper surface of the heating layer 511 to generate heat The heat generated in the layer 511 may pass through the protective layer 52 and radiate to the outside to heat the air inside the chamber or the like where the drying apparatus DS of the present invention is installed to provide heat.

As a result, the heat generated from the heating layer 511 is directly heated to the one side of the tape fabric 1 and the indirect heat that heats the inside air of the chamber or the like through the protective layer 52 is used. The adhesive liquid coated on one surface can be dried and cured.

In addition, the protective layer 52 may be made of a polyimide (PI) film.

In addition, an insulating film may be further provided on the planar heating element 51 to insulate the heating layer 511, and the insulating film is made of an insulating resin material, thereby preventing electricity from leaking.

Meanwhile, as shown in FIG. 12, the planar heating element 51 is

A heating layer 511,

A pair of electrode members 512 arranged parallel to each other on the heating layer 511 to receive power from the power supply unit 60,

A plurality of heating members 513 disposed between the electrode members 512,

Buffer member 514 disposed between each electrode member 512 and each heating member 513

Is made of

In more detail,

As shown in FIG. 14, the planar heating element 51 may be formed in a sheet form, may be formed in a rectangular plate shape when viewed from the top, and as described above, the length or width of the object to be dried, that is, a tape fabric ( It may be variously modified and changed in consideration of the width of 1) and the separation distance between two adjacent rollers 2.

The heating layer 511 is supplied with electricity to generate heat, and receives electricity to generate heat using electrical resistance. The heat generated is transferred to one side of the tape fabric 1 to dry and cure the adhesive.

In addition, a plurality of heating members 513 to be described later in the planar heating element 51 may be provided and may be horizontally or vertically spaced at regular intervals along the longitudinal direction of the planar heating element 51.

The heating member 513 is capable of generating heat by electrical resistance, and is made by processing carbon nanotubes (CNT) and carbon in the form of a tube (tube) in which hexagons made of 6 carbons are connected to each other to form a tube. It is composed of a composite material such as graphite, which has a plate-like structure and excellent horizontal thermal conductivity.

The electrode member 512 may be disposed to be the same as the longitudinal direction of the planar heating element 51, receives power (electricity) from the power supply unit 60, and is made of a material such as copper with high electrical conductivity.

The electrode member 512 may apply electricity to the heating member 513, and a pair may be provided so that the heating member 513 may be disposed between them. As a result, both ends of the heat generating member 513 are electrically connected to each electrode member 512, so that the heat generating member 513 is supplied with electricity to generate heat.

In addition, the buffer member 514 is disposed between the heating member 513 and the electrode member 512, a part of which is located above the heating member 513 and the other part of the electrode member 512. It is configured to be stacked on the bottom. That is, the buffer member 514 is provided at both ends of the heating member 513, and a pair of electrode members 512 are provided at the ends of each buffer member 514, respectively.

In the heating layer 511, carbon has a resistance value of about 1400 to 4000 uΩ/cm, and copper has a resistance value of about 0.1 to 2 uΩ/cm, so the difference in resistance between the heating element 513 and the electrode member 512 is very high. Due to the size, if there is no buffer area in the middle, and they are directly physically connected to each other, conductivity may be deteriorated or local overheating may occur. In addition, the heating member 513 made of carbon material and the electrode member 512 made of copper are very low in adhesion, and thus, when the planar heating element 51 is folded or unfolded, damage such as a short circuit is likely to occur.

Therefore, the buffer member 514 serves as an electrical buffer while electrically connecting the heating member 513 and the electrode member 512. The buffer member 514 is preferably a material having excellent electrical conductivity, and for example, silver paste may be used or may be implemented as a conductive adhesive layer. At this time, it may be a conductive adhesive layer made of a silicon (Si)-based inorganic adhesive or a carbon-based organic adhesive. The conductive adhesive layer provides an adhesive strength of 3 MPa or more, has a resistance value of about 0.1 to 2 uΩ/cm, and may have excellent elasticity.

In addition, since the conductive adhesive layer contains an adhesive component, the heating member 513 and the electrode member 512 may be physically bonded. Accordingly, it is possible to prevent a short circuit from occurring in the heating member 513 and the electrode member 512. In addition, the conductive adhesive layer may contain a material having excellent conductivity. Accordingly, the conductive adhesive layer may electrically connect the heating member 513 and the electrode member 512. In addition, the conductive adhesive layer may be provided with a flexible and elastic material. Accordingly, even when the planar heating element 51 is folded, bent, or bent, damage to the electrode member 512, the conductive adhesive layer, and the heating member 513 can be prevented.

On the other hand, the copper plate 54 is configured to cover the entire lower surface of the thermal diffusion coating layer 53 disposed under the heating layer 511, and the copper plate 54 configured as described above is tape when drying on the tape fabric 1 The planar heating element 51 may be protected from the adhesive liquid applied to one surface of the fabric 1.

In addition, although the copper plate 54 is a plate-like structure made of copper having high thermal conductivity, it may be made of various materials within a range that satisfies a condition that can transmit heat well. For example, it may be replaced with a polyimide (PI) film or the like.

14, a plurality of through-holes 541 are formed in the copper plate 54, and each of the through-holes 541 is more easily passed through the heat radiating from the planar heating element 51 so that the tape fabric is passed through. It helps to be delivered to one side of (1).

On the other hand, as shown in FIG. 17, the present invention further includes a blower fan 70 which is arranged to be spaced apart from the protective layer 52 of the heating sheet 50,

First, in the copper plate 54, the wind generated by the blowing fan 70 passes through the through hole 541 that is not blocked by the planar heating element 51 among the through holes 541, so that the tape fabric is passed through. It is blown toward one side of (1).

As a result, the adhesive liquid applied to one side of the tape fabric 1 can be dried and cured by simultaneously using the heat generated by the planar heating element 51 and the wind blown from the blowing fan 70.

On the other hand, as shown in FIG. 17, the present invention is disposed at the outlet side of the blowing fan 70, that is, the outlet from which the wind comes out so that the wind generated by the blowing fan 70 is concentrated toward one surface of the tape fabric 1 Further comprising a guide cover 80 to guide,

The guide cover 80 is disposed adjacent to one surface of the tape fabric 1 and the inlet 81 disposed on the outlet side of the blowing fan 70, and the width corresponding to one surface of the tape fabric 1 It consists of a hollow cover structure with an outlet 82 having.

In particular, the cross-sectional space structure of the upper and lower light (上狹下廣) is gradually increased from the inlet 81 to the outlet 82.

Therefore, the wind generated by the blowing fan 70 passes through the inlet 81 and is discharged through the outlet 82, and is concentrated toward one surface of the tape fabric 1. At this time, the wind through the guide cover 80 does not leak to the outside as much as possible, so that it can be concentrated only on one side of the tape fabric 1.

In the above description of the present invention with reference to the accompanying drawings, the "transfer of the tape fabric and the coating surface drying treatment system" having a specific shape and structure was mainly described, but the present invention can be variously modified and changed by those skilled in the art, These modifications and variations should be construed as falling within the protection scope of the present invention.
