Description

Guide roller for continual overlap of laminating sheet}

The present invention improves the structure of the guide roller of the overlapping means formed on the feed supply of the object in the laminating machine for laminating a film (OPP film) of the synthetic resin to the object to be processed by a variety of sheet paper, inducing smooth progress of the object In addition, it relates to a guide roller that allows the front and rear ends of the workpiece to be more uniformly and stably overlapped.

In general laminating apparatus, sheet paper, which is an object to be processed, which is introduced at a predetermined interval from one side of the main body, and a film paper provided through a winding roller at the upper portion of the sheet is compressed and melted by an upper and lower pressure rollers, so that the film paper is on one side of the sheet. As a result of fusion, this laminated sheet is used as a cover for printed materials such as brochures, record jackets, book covers, and various fabrics such as shopping bags. Since the surface is glossy, the appearance of the product is more beautiful and high quality, so it is widely used.

In addition, the sheet paper described above is generally supplied in the form of a sheet cut in a predetermined length, such sheet sheet sheet is to be loaded to the transfer device by the operator and a separate supply means.

In addition, the sheet paper that is moved to the heating roller and the pressing roller side in the conveying device is to be compressed and melted with the film paper with the adhesive layer formed, in the case of a gap between the sheet paper and the sheet paper during this pressing process, the adhesive flows between the gap between the press roller Alternatively, since the adhesive is adhered to the surface of the heating roller, it is inconvenient to remove it in this case. Therefore, the worker's artificial overlapping work or the rotation speed of the front and rear guide rollers are differently set by the speed difference of the guide roller. Since the front and rear sheet paper is superimposed on each other, a method of allowing the film paper to be melted on one side of the sheet paper continuously supplied thereto is used.

After the lamination is completed, the laminated sheet is finished by laminating each sheet of paper in the opposite direction so that the film sheet formed on the overlapping part is cut off to obtain the laminated sheet in the same state as the original feeding state. Will be.

However, in the above-described overlapping work of the sheet paper, since the worker has to supply each sheet paper by hand by hand, the work time is very delayed and the length of the overlapping sheet paper is not constant. If the defective rate of the product rises and the overlapping section is made too long, lamination is not performed as much as the overlapping section, and thus the amount of sheet paper loss increases.

In addition, when the overlapping section is not made due to the operator's mistake, the adhesive is adhered to the surface of the heating roller and the pressing roller as in the prior art, and thus, the work has to be stopped.

The method of overlapping by setting the rotation speed of the front and rear guide rollers differently has the problem that the interval of the sheet paper to be supplied has to be constant, and the overlapping section of the sheet paper is not uniform, which makes it impossible to produce a uniform product. It is.

The present invention was conceived to eliminate the problems as described above, in the overlapping means formed between the sheet conveying device and the laminating device of the sheet and film paper, easy to move left and right while maintaining a constant elasticity up and down, and before and after the roller The guide roller is adjustable in length, but the guide roller on the advanced side is driven by the power of the driving motor to be automatically rotated during the overlapping process of the sheet paper.

It is very easy to install and adjust the guide roller according to the size of the sheet, and it rotates up and down in connection with the feeding speed and the overlapping action of the sheet, so that it is possible to accurately and uniformly stack the sheet, and the thickness of the sheet is maintained by maintaining a constant elasticity by the spring. The purpose of the present invention is to provide a guide roller for continuous overlapping of laminating sheet paper, which allows the sheet paper to be transported by pressing the sheet paper at an even pressure.

The guide rollers 12 and 12 'are separately formed by the upper support 14 and the lower support 15 which form insertion holes 13 and 13' inserted into the support rods 11 and 11 ', respectively. The upper support 14 is screwed to the fixing bolt 17 of one side and the coupling bolt 18, 18 'of the center and the other side of the adjustment bolt 19, the spring 16 is installed on the end, respectively, , The lower support 15 forms a long hole 20 on one side to form a pressure roller 21 coupled thereto,

An end of one side of the support rod 11 is coupled to the support arm 23 is equipped with a rotary roller 22, the rotary roller 22 is to be in contact with the drive gear 25, the rotary cam 24 is formed, the drive The gear 25 is configured to interlock with the drive shaft 27 of the overlapping means 10 by a plurality of connecting gears 26 and 26 '.

In the drawings, reference numeral 30 denotes an overlapping cam, 31 a protruding piece, 32 a sheet paper, 33 a film paper, and 34 a driving motor.

Referring to the operation of the present invention by the configuration as described above in more detail by the accompanying drawings as follows.

First, a schematic overall operation relationship of the overlapping device of the present invention sheet paper, the sheet paper 32 having a predetermined width from one side of the main body 1 is the sheet feeding device (2), for example, the suction head at a predetermined interval (not shown in the drawing). When the sheet paper 32 is absorbed by the sheet conveyer 32 and placed on the conveyor conveying apparatus 3, each sheet 32 is rotated in the direction of rotation of the conveyor conveying apparatus 3 by the conveyor conveying apparatus 3 which is rotated. To be transported.

The sheet 32 thus conveyed is stopped for a predetermined time by the lifting rod 8 and the plurality of protruding pieces 31 which are lifted up and down, and then proceeds again, and the line of the sheet paper 32 continuously supplied during such a stop time. The rear end is conveyed by overlapping.

In addition, the sheet paper 32, which is overlapped and continuously advanced by the above-described operation, is simultaneously formed between the film paper 33 having the adhesive applied to one surface by the adhesive supply unit 4, the heating roller 6, and the pressing roller 7. The sheet paper 32 and the film paper 33 thus supplied are laminated in a molten state on one surface of the sheet paper 32 while the film paper 33 is melted by the high heat of the heating roller 6.

The sheet paper 32 that has undergone such a laminating process is to be rolled up in a roll form by a separate winding means or to separate and store each sheet paper 32 by a cutting means.

The laminating apparatus, which is laminated by the above-described action, is a line of sheet paper 32 supplied in a sheet by the overlap means 10 formed between the conveyor conveying apparatus 3 and the heating and pressing rollers 6, 7, The rear end is supplied to overlap a certain width, which will be described in more detail,

The sheet paper 32 conveyed along the conveyor conveying apparatus 3 is first guided between the conveying roller 9 and the guide roller 12, and the pressing and driving motor 34 of the guide roller 12 and the conveying roller 9 are carried out. It is moved to the lifting rod 8 side having the protruding piece 31 by the rotational force of the feed roller 9 is rotated by receiving the power of the).

The sheet paper 32 thus moved is lifted up and down the lifting rod 8 and the projecting piece 31 by the rotation of the overlapping cam 30 just before the end of the sheet paper 32 approaches the projecting piece 31. At the same time, the supporting rods 11 of the guide rollers 12 rotated so that the pressing rollers 21 of the guide rollers 12, which were pressing the sheet papers 32, were raised. As the pressure is removed, the sheeting will not proceed anymore.

During the stagnation time of the sheet paper, the sheet sheets on the rear side which are continuously supplied are overlapped with the end portions of the sheet sheets which have been pre-input. Since the sheet paper is conveyed at the same time, the sheet paper which is divided and supplied is conveyed in a state where the front and rear ends are overlapped, so if the process is repeated continuously, the sheet paper 32 in which the front and rear ends are overlapped is continuously supplied and the film paper 33 It is laminated by).

Looking at the operation of the guide rollers 12 and 12 ', the guide rollers 12 and 12' are conveying rollers 9 and 9 'formed before and after the protrusion pieces 31 as shown in FIG. Opposed to and fixed to the supporting rods 11 and 11 ', the pressing rollers 21 of the feed rollers 9 and 9' and the guide rollers 12 and 12 'are abutted and rotated. will be.
