DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

2 to 4, the tension plate assembler according to the present invention mainly includes a film supply unit 10, a sheet supply unit 20, a joint unit 30, a tension adjustment unit 40, a cutting unit 50).

The film supply unit 10 according to the present invention includes a film drum 11 on which a film sheet 1 is wound in a roll form and supplies the film sheet 1 to the joint unit 30,

Conventionally, the film web 1 is conveyed through the driving of the laminating rollers while the film web 1 is being held by the laminating rollers of the laminating unit 30. In contrast, the film web supplying unit 10 of the present invention has a separate A driving roller 12 is further provided.

Between the film drum 11 and the drive roller 12, one or more guide rollers 13 may be disposed to maintain tension of the film 1.

Reference numeral 11A denotes an auxiliary film drum 11A on which the film 1 is wound and stands by with the film 1 held in a pedestal 13a under the guide roller 13, The film laminas 1 of the auxiliary film drum 11A are continuously supplied, so that the work loss due to drum replacement can be reduced.

Next, the sheet feeding unit 20 of the present invention feeds the sheet 2 to the joining unit 30. In the figure, the sheet 2 cut in advance and having a predetermined size is conveyed and supplied through the conveyor 21 However, it is also possible that the sheet paper is rolled up and fed as in the case of the film sheet 1 as the case may be.

When a roll-shaped sheet is fed, the tension of the sheet can be maintained through various rollers.

The conveyor 21 of the sheet feeding part 20 is a conveyor of a known type for conveying the sheet 2 placed on the upper part to the joining part 30 and is conveyed through a sprocket (or a conveying roller) connected to a driving motor A mode including a belt 21A rotating in one direction (see FIG. 5), or a mode in which a plurality of conveying rollers connected to a driving motor are provided and rotated in one direction.

The conveyor 21 of the present invention is provided with a height adjusting means to adjust the height of the rear end portion 21b with respect to the front end portion 21a so that the inclination angle of the conveyor 21 is adjusted, It is possible to adjust the entry angle of the sheet paper 2 supplied to the jig 30.

In this case, the size (more precisely, the width) of the sheet 2 may be different, and therefore, as shown in Fig. 5, on one side of the upper side of the conveyor 21, The aligning member 22 is provided so as to be movable in the lateral direction of the conveyor 21 so that the position of the aligning member 22 is adjusted according to the size of the sheet 2, To be fed to the correct position.

2 to 4, the jig 30 of the present invention includes upper and lower jersey rollers 31 and 32. The film jersey 30 includes a film 1 and a sheet of paper, (2) is pressed to join the flat plate.

The jig (30) is operatively connected to the conveyor (21) of the sheet supply unit (20).

The jagged portion 30 includes a first roller portion 30A and a second roller portion 30B so that double layered paper is formed on the overlapped film 1 and the sheet 2.

The first roller 30A of the first pair of rollers 31 is disposed at a position adjacent to the sheet feeding portion 20 and is disposed at a position adjacent to the second roller 30 of the second pair of rollers 32. [ The portion 30B is disposed at a predetermined distance in front of the first roller portion 30A so that the film sheet 1 and the sheet paper 2 that are firstly joined together by the first roller portion 30A are separated from the second roller portion 30B The second lap is made.

As shown in FIG. 6, the first papermaking roller 31 further includes at least one pressing portion 31a protruding along the circumferential direction of the outer circumferential surface.

The pressing portions 31a may be spaced apart from each other by a predetermined distance along the longitudinal direction of the first papermaking rollers 31, and it can be seen that two pressing portions 31a are provided in the drawing.

The pressing portion 31a partially presses the overlapped film 1 and the sheet paper 2 (here, partial pressing means that the pressing force is concentrated compared to a portion where the pressing portion 31a is not formed) .

That is, in the conventional laminating machine, the film 1 and the sheet 2 are simply pressed and attached using a general cylindrical roller. In this case, even if double laminating is performed, the pressing force of the roller is dispersed, On the contrary,

The present invention improves the adhesive strength by partially pressing the film sheet (1) and the sheet paper (2) by the pressing portion (31a) in the first roller portion (30A).

The second joining roller 32 of the second roller portion 30B is constituted by a general cylindrical roller and the portion pressed like the groove due to the pressing portion 31a of the first roller portion 30A, (30B) and flattened to complete the lamination.

Next, as shown in FIGS. 2 to 4, a tension adjusting unit 40 is further provided between the film supply unit 10 and the joint 30.

The tension adjuster 40 of the present invention adjusts and maintains the length and tension of the film sheet 1 fed to the joint 30 so as to prevent defective joints and deformation of the flat plate 3 And is realized through the tensionless roller 41 whose position is displaced.

The tension roller 41 is basically similar to the guide roller for guiding the conveyance of the film 1, whereas the conventional tension roller is fixedly provided with the guide roller, whereas the tension roller 41 of the present invention is fixed at the first position Between the first position and the second position.

As described above, since the film sheet supplying section 10 and the sheet feeding section 20 and the joining section 30 operate independently of each other as described above, the tension roller 41 moves to the second position P2 After the film sheet supply section 10 is driven to secure the length of the film sheet 1 to be fed to the joint section 30,

The tension roller 41 is rotated by the length in which the tension roller 30 is driven and the film sheet 1 and the sheet paper 2 are joined together while the driving of the film sheet supplying part 10 is stopped, The tension of the film 1 is adjusted while moving to the position P1.

That is, since the guide roller (s) are fixedly provided between the film feeding section 10 and the leg section 30, the conventional lamination machine is configured such that when the film 1 is initially set, The film sheet 1 is put into a lint state by the driving of the jig 30 and the deformation of the flat plate 3 occurs due to the restoring force of the post-

The present invention is characterized in that the film sheet 1 and the sheet paper 1 which pass through the joint portion 30 are stretched by the tension roller 41 moved to the second position P2, 2 while the tension roller 41 moves from the second position P2 to the first position P1 by adjusting the length of the film 1 to be fed into the leg portion 30, So that the above-described problems can be avoided.

In this case, the displacement direction of the tension roller 41 is not limited to the up, down, left, and right directions, but it is more preferable that it is installed to transversely move in the horizontal direction in the structure with the angle adjusting roller 42 described later.

In addition, the tension adjusting unit 40 of the present invention further includes an angle adjusting roller 42 which is adjustable in height between the tension adjusting unit 40 and the jig 30.

The angle regulating roller 42 finally guides the film 1 fed to the jamming unit 30 so that the film sheet 1 enters the jamming unit 30 in accordance with the displacement of the tension roller 41 The angle of entry of the film 1 can be kept constant,

At the same time, by adjusting the height of the angle regulating roller 42 itself, the angle of entry of the film sheet 1 can be set variously.

Accordingly, the present invention can variously set the entry angles of the sheet paper 2 and the film paper 1 through the conveyor 21 whose height of the rear end portion 21b is adjusted and the angle adjusting roller 42 Thickness, size, and the like of the sheet paper 2 and the film sheet 1, it is possible to perform the lapping operation by setting the optimum conditions under which no joint failure occurs.

The cutting portion 50 of the present invention is provided on the front side of the joint portion 30 (more strictly, the second roller portion 30B) to cut the film sheet 1 and the sheet paper 2, (3) can be discharged.

The cutting portion 50 can be realized by a vertically driven cutter or the like. When the film sheet 1 is joined to the cut sheet 2 as shown in the drawings of the present specification, the cutting portion 50 is continuously discharged Only the film sheet 1 will be cut,

Unlike the drawing, in the case of laminating the film 1 to the roll-shaped sheet, the cutting portion 50 cuts both the sheet and the film continuously discharged.

Hereinafter, the operation and effect of the tension plate assembler of the present invention having the above-described structure will be described in detail.

3, when the film 1 to be wound is set, the film 1 is wound around the guide roller 13, the driven roller 11, Is guided to the joint portion (30) via both the roller (12), the tensionless roller (41) and the angle adjusting roller (42).

When the tension plate 41 is moved to the second position P2 and the driving roller 12 is driven, the length (that is, the length of the sheet 2) The film sheet 1 is loosened by the film drum 11 as much as possible.

When the driving of the film feeding unit 10 is stopped, the sheet feeding unit 20 and the joining unit 30 are driven together as shown in FIG.

As the sheet 2 of the conveyor 21 enters the first roller portion 30A of the joint portion 30, the film 1 guided to the first roller portion 30A also enters the first roller portion 30A, And are primarily joined together by the rollers 31.

At this time, the tension roller 41 at the second position P2 moves to the first position P1 at a speed corresponding to the driving speed of the jogger 30, and the film 1 passes through the jogger 30, While keeping the tensile force for pulling the film 1 at the jamming portion 30 constant.

That is, since the driving roller 12 is in a stopped state at the start of the lapping, the state in which the film 1 is pulled up with a certain force is maintained through the displacement of the tension roller 41, The length of the film 1 between the supporting portions 30 (more strictly, between the driving roller 12 and the angle adjusting roller 42) is adjusted and supplied to the joining portion 30.

In this case, a method in which the individual sheets of paper 2 cut by the operator are put on the belt of the conveyor 21 while the conveyor 21 is continuously driven at a constant speed is also possible.

The film 1 passing through the joint portion 30 is firstly joined while being partially pressed through the pressing portion 31a of the first roller portion 30A while maintaining the constant tension and the second roller portion 30B So that the film 1 and the sheet 2 are firmly adhered to each other.

When the lapping is completed, the cutting portion 50 is operated and cut into a single flat plate 3, whereby the flat plate 3 with the film sheet 1 and the sheet paper 2 laminated is finally discharged.

Therefore, the tension of the film sheet 1 supplied to the joint portion 30 is maintained at a proper level with appropriate strength, so that the post-joint film sheet 1 does not have a restoring force and the deformation does not occur It is possible to automatically produce continuous tension plates (3).

On the other hand, the sheet paper 2 used for the lamination does not have a completely flat surface over the entirety due to the characteristics of the material, manufacturing variations, etc., and can have a predetermined thickness deviation for each part of the whole surface.

Therefore, when the sheet 2 is passed between the rotating joining rollers, the height of contact with the joining rollers 31 and 32 is varied due to the thickness deviation of the sheet 2, The feeding direction of the sheet 2 may be distorted.

In order to solve the above problems, the present invention introduces a height correction means (S) to the lapping rollers (31) (32) of the lapping portion (30).

Hereinafter, the height correcting means S of the present invention will be described on behalf of the first roller portion 30A.

6 to 8, the height correcting means S includes a drive shaft 33 having a screw portion 33a formed on the outer peripheral surface thereof, a pressing member 34 coupled to the screw portion 33a, And an ascending / descending member 36 connected to a side end of the rotary shaft 21a (31b) of the lapping roller 31A and ascending and descending by contact with the pressing member 34. [

The height correcting means S having the above configuration is disposed on both left and right sides of the upper first papermaking roller 31A to individually correct the left and right side end heights of the upper first papermaking roller 31A in a horizontal state.

More specifically, the height correcting means S for correcting the height of the right end of the rotary shaft 31b of the upper first papermaking roller 31A will be described in more detail.

The driving shaft 33 is installed on the upper first lint roller 31A and connected to the driving means 33A such as a motor to rotate in both directions and has a screw portion 33a formed on one or all of the outer circumferential surface in one direction Respectively.

The pressing body 34 is a block-shaped member and is formed as a pressurized slant surface 34A whose lower surface is inclined in one direction and is screwed to the screw portion 33a of the driving shaft 33. [

Although not shown in the drawing, the pressing body 34 may be provided with fixing means (not shown) such as a stopper to prevent the rotation of the driving shaft 33 during the rotation of the driving shaft 33, So that when the driving shaft 33 rotates in both directions, the pressing body 34 is installed so as to move laterally and laterally on the screw portion 33a.

The upper surface of the ascending / contracting body 36 is formed as a corresponding inclined surface 36A corresponding to the pressing inclined surface 34A so that the pressure increasing inclined surface 34A and the corresponding inclined surface 36A are in contact with each other Respectively.

The lower end of the elevating bar 38 is connected to the rotating shaft 31b of the upper first joining roller 31A and the elevating bar 38 is coupled to the elevating bar 36. [ So that the height of the rotary shaft can be adjusted.

Here, the elevation rod 38 is connected to the rotation axis of the first pair of pile roller 31A, but is not directly connected to the rotation axis (because the rotation axis must be rotated), but the housing 31c, Which does not interfere with the rotation of the motor.

6, when both ends of the rotary shaft 31b of the upper first joining roller 31A are provided in a housing 31c having a bearing (not shown) and a motor, etc., Is hinged to the outside of the housing 31c, the rotation of the rotation shaft is not interfered with, even if the height of the housing is adjusted according to the raising and lowering of the raising and lowering rods 38. [

Of course, in this case, a link structure in which a driving force is transmitted in correspondence with a tilt change of the rotating shaft of the driving means and the rotating shaft of the motor or the like will be adopted.

Therefore, when the pressing body 34 is moved transversely to one side (left side in the drawing) by unidirectional rotation of the drive shaft 33 as shown in Fig. 8, the corresponding inclined face 36A, So that the elevating member 36 and the elevating bar 38 are lowered,

When the pressing body 34 transversely moves to the other side (the right side in the figure) by the rotation of the drive shaft 33 in the other direction, the pressurization of the pressurized slant surface 34A is released and the elevating body 36 and the ascending / .

At this time, a method of automatically elevating the ascending / descending body 36 and the ascending / descending rods 38 as much as the pressing of the pressing slope 34A is released by using an elastic means (not shown) Since elevation due to the elastic means may cause a height adjustment error in accordance with the elastic force,

The present invention introduces a locking protrusion 35 connecting between the pressing body 34 and the ascending / descending body 36 to force the ascending / descending body 36 to ascend.

More specifically, a locking protrusion 35 protrudes from the right and left side surfaces of the pressing body 34,

The ascending / descending member 36 is provided with a guide groove 37 formed in a shape corresponding to the inclination of the corresponding inclined surface 36A,

The engaging protrusion 35 is slidably engaged with the guide groove 37.

Therefore, when the pressing body 34 is transversely moved by one side, when the ascending / descending body 36 is lowered by the pressing inclined surface 34A, the engaging projection 35 is moved to one side along the inclination of the guide groove 37 Slidably moved,

When the pressing body 34 is laterally moved to the other side, the engaging protrusion 35 is slid to the other side along the inclination of the guide groove 37, so that the lifting body 36 is lifted, 31A and the elevating rod 38 connected to the rotating shaft of the elevating rod 31A.

Therefore, a sensor (not shown) for detecting the thickness deviation of the sheet 2 is provided on the sheet supply unit 20, and a control unit (not shown) controls the height correction unit S The height of the right and left sides of the first joining roller 31A can be automatically corrected by rotating the drive shaft 33. [
