The sheet feed roll 20 protrudes from the upper plate 12. The sheet feed roll is coupled to the top plate and rotatable with a bearing, and the sheet feed roll 20 is directly wound on the sheet feeder, or a reel in which the sheet 91 is wound is mounted to enable continuous feeding of the sheet.

The sheet 91 wound on the sheet supply roll 20 is pulled by a pair of take-out rolls 30 and supplied to the adhesive supply means 40 to be described later. The pair of take-out rolls 30 are rotatably bearing coupled to the top plate, but the two rolls are installed to be in contact with each other, and a sheet 91 is inserted between the two rolls 30 to supply the sheet by the rotational force of the take-out roll. Let this be done. In addition, the two take-out rolls 30 in contact with each other may be driven to supply power to each other, or may be driven only in one of the take-out rolls, and the other may be passively rotated. In addition, the outer surface of the take-out roll 30 is preferably such that a cushion layer such as rubber or synthetic resin is formed to facilitate pressing or gripping the sheet.

In addition, a guide pin 13 may be installed between the sheet feed roll 20 and the draw roll 30 to prevent the sheet 91 from being caught by other components centrally disposed.

The adhesive supply means 40 applies an adhesive to one surface of the sheet 91 supplied from the draw roll 30.

As shown in FIG. 4, the adhesive supply means 40 includes an adhesive reservoir 41 installed on the bottom of the upper plate 12, a housing 42 and a screw roll 43 for transferring the adhesive of the adhesive reservoir to the upper plate. It consists of.

The adhesive reservoir 41 is a storage unit for storing the adhesive to be applied to the sheet, it can be used to be disposed on one side of the upper plate, the sheet adhesive apparatus of the present invention can be attached to the side of the inner side as well as the outside of the window-type door Since it is to be installed in the bottom of the top plate to minimize the portion protruding to the top. In addition, the top plate may be formed with a cover 121 so as to easily add the adhesive to the adhesive reservoir 41 to open the lid, and then the adhesive may be supplied to the adhesive reservoir.

Next, the housing 42 is a cylindrical body, the lower end of which is positioned below the adhesive reservoir, and the upper end is formed to protrude through the upper plate. The housing 42 has one side of the portion protruding to the top of the upper plate and one side of the portion supported by the adhesive stored in the lower adhesive reservoir 41 to open the adhesive flowing into the upper portion.

This upward supply of adhesive is possible by means of a screw roll 43 installed in the housing 42. The screw roll is rotated by the power of the motor 60, a plurality of spiral grooves 431 is formed on the outer surface, the adhesive is raised by the spiral grooves 431 during rotation. The adhesive raised along the spiral groove is exposed to the outside through the upper opening of the housing, and the adhesive is applied by contacting one surface of the sheet 91 supplied from the withdrawal roll 30 to the exposed outer surface of the screw roll 43. Will be made. Spiral grooves formed on the outer surface of the screw roll 43 is preferably formed as a small groove by supplying an excessive adhesive when the spiral height is formed large, so that the adhesive is supplied to the upper portion by a small amount. The screw roll is preferably formed to be similar to the inner diameter of the housing so that the rising of the adhesive is facilitated so that the screw thread is pushed up by the adhesive as the inner diameter of the housing 42 and the screw roll thread are rotated in contact with each other. In addition, the screw roll 43 extends and protrudes the screw roll shaft 43, which is a central shaft, to the lower portion of the adhesive reservoir so that power is transferred to the protruding portion. At this time, in order to prevent the leakage of the adhesive stored in the contact portion of the screw shaft and the adhesive reservoir, the watertight packing may be installed, or various known methods may be applied.

The attachment roll 50 installed in close proximity to the adhesive supply means 40 attaches the sheet 91 coated with the adhesive to the inner side of the window-shaped door. The attachment roll 50 is formed to protrude to the upper portion of the upper plate, it is preferable to be rotatable by bearing coupling with the upper plate.

In addition, it is preferable to transmit power to the attachment roll so as to be easily attached to the inner surface of the window-type door to enable automatic rotation. For example, when the attachment roll 50 is automatically rotated and the user presses the inside of the window door 90 with the attachment roll with the seat 91 therebetween, the attachment roll is rotated to push the window frame in the direction of rotation so that the window is moved. It is attached to the frame.

In addition, it is preferable that the attachment roll 50 also forms a cushion layer on the outer surface like the draw roll 30 so that the sheet is in close contact with the sheet when the inner sheet of the window frame is attached to prevent the window frame from being lifted by the air layer. Do.

On the other hand, a pair of guide plate 70 may be further installed between the take-out roll 30 and the screw roll 43 of the adhesive supply means. The guide plate is a device for guiding the sheet 91 continuously supplied from the take-out roll 30 in the tangential direction of the screw roll 43.

In addition, the sheet 91 in contact with the adhesive supply means 40 is applied to the upper portion by the spiral groove 431 of the screw roll 43 is rotated to be gradually lifted in the vertical direction of the top plate. As such, when the sheet 91 is spaced apart from the upper plate surface, the sheet 91 is displaced from the side of the window frame supplied in contact with the upper plate so that the sheet cannot be attached at the correct position. Therefore, as shown in FIG. 5, the guide plate 70 may be formed with a long groove 71 vertically, and a fixing screw 72 may be inserted into the long groove to fix the bolt by tightening bolts. When the fixing screw 72 is fixed and the seat 91 is supplied to the lower portion of the fixing screw 72, the fixing screw 72 is pressurized from the upper portion of the sheet 91 which is subjected to upward pressure by the rotation of the screw roll 43. By doing so it can be prevented to rise to the top in the process of applying the adhesive.

In addition, as shown in FIG. 6, a fixing nut 51 for blocking the rise of the sheet 91 may be mounted on the attachment roll 50 for attaching the sheet 91 coated with the adhesive to the window-shaped door. When the fixing nut is installed on the attachment roll, the seat 91 is pressurized by the position fixing screw 72 of the guide plate on both sides of the screw roll 43 and the fixing nut 51 of the attachment roll. The rising pressure of the roll can be canceled out.

In addition, when the width of the seat 91 to be attached is changed, the position fixing screw 72 to loosen the bolt to move to the same height as the seat width along the long groove 71 of the guide plate 70 and then tighten the bolt again The fixing nut 51 can be fixed at an appropriate position according to the seat width by loosening the screw, moving the nut, and then tightening the screw again.

Next, in the present invention, in order to make the amount of adhesive applied to the sheet 91 constant, the support roll 80 to which the pressure plate 81 is attached may be further mounted. As shown in FIG. 3, the support roll 80 is installed to be rotatable by manual or hydraulic pressure in close proximity to the surface where the screw roll 43 and the sheet 91 come into contact with each other. The support roll 80 has a pressure plate 81 attached to the outer surface to press the screw roll 43 which is in contact with the seat 91 end portion of the pressure plate which is located far from the axis of the support roll when rotated to one side to the screw roll The adhesive is buried in the sheet 91. Therefore, by making the gap between the end of the pressing plate and the screw roll thinner than the sheet thickness, it is possible to adjust the pressure so as to uniformly bury the adhesive.

On the other hand, the amount of adhesive buried in the sheet may be controlled by the pressure of the pressure plate, but as shown in Figures 2 and 7 the pressure plate 81 is to be made only the pressure of the sheet, the amount of adhesive on the screw roll Silver can be adjusted by the adhesive amount control plate 82.

The adhesive control plate 82 is positioned before the sheet guided by the guide plate is in contact with the screw roll 43 to scrape the outer surface of the screw roll to uniform the amount of adhesive on the surface of the screw roll. The adhesive amount adjusting plate 82 is the shaft is coupled to the rotation bar 84, the rotation bar is rotated from the shaft in accordance with the degree of protrusion by tightening the adjustment screw 83 installed on the upper end of the housing of the adhesive supply means (40). This is done to adjust the position of the adhesive amount control plate in the housing.

For example, when the adjusting screw 83 is tightened to one side, the rotating bar 84 rotates in one direction, and the adhesive amount adjusting plate 82 coupled to the rotating bar is spaced apart from the screw roll outer surface or close to the screw. The amount of adhesive on the outside of the roll can be controlled.

The sheet bonding apparatus 10 for the inner surface of the furniture window having the above structure is further provided with a motor 60 for transmitting power. The motor is installed under the upper plate of the table to transmit power to each roll.

For example, as shown in Figure 1 of the pair of take-out roll 30 extends the take-out roll shaft 311, which is the central axis of one side take-out roll, and the attachment roll shaft 511, which is the center axis of the attachment roll 50, to the lower side of the upper plate. The screw roll shaft 432, which is the central axis of the screw roll 43, is extended to the lower portion of the adhesive reservoir 41. Gears 611 are formed on each of the extended take-out roll shaft 311, the attachment roll shaft 511, and the screw roll shaft 432 on the same plane, and the gears formed on the three shafts are organically connected to each other. As a connection method, various methods such as a chain belt and gear mesh can be applied. In this way, by connecting the power of the motor to any one of the state connected to each other by connecting the drive shaft to the drive shaft it is possible to transfer the motor power to each roll.

In addition, the motor 60 may transmit power to each shaft through the speed reducer 61, and may install a separate operation pedal to interrupt the transmission of power. The interruption of the power transmission may be applied to a variety of methods, such as a brake for holding the drive shaft by the hydraulic pressure, a motor power short circuit, a reduction gear clutch, a gear clutch in the power gear transmission system.

In addition, the sheet bonding apparatus 10 having the above configuration has an attachment roll 50 and a draw roll 30 disposed on both sides of the screw roll 43 as shown in FIG. 3, and the draw roll and the screw roll. The guide plate 70 and the support roll 80 are disposed between the screw rolls as close as possible, and the sheet supply roll 20 for supplying the sheet to the draw rolls is positioned above the screw rolls 43 so that the table top plate Each part protruding into the center is placed in the smallest concentric circle so that the automatic seat can be attached to the inner side of the closed window door or the edge of the inner hole of the window door.
