Description

[Detailed description of the invention] The present invention is an invention that provides a convenient and economical laminator that can reliably perform laminating processing at high speed and can also use rolled resin films.

As shown in Fig. 3, the mechanism of the conventional laminator is an ordinary feeding roller 2 that is not a heat roller.
0, 20' and the pressure rollers 21, 21', there are two upper and lower plate-shaped heater mechanisms 22, 2.
2' are arranged opposite to each other, and the processing material obtained by polymerizing resin films 23 and 24 for laminating the R side of a material such as a paper board is transferred from the feeding rollers 20 and 20' to the plate heater mechanism 22, 22', the resin films 23 and 24 are heated and fused to the material R as they pass through the heater, and then the resin films 23 and 24 are pressed and bonded to the material R by the pressure rollers 21 and 21' in the next order to perform lamination. The single plate-shaped heater mechanism 22, 22' requires a long waiting time to reach a high temperature at the start of work, resulting in a large power loss and being uneconomical.
Work starts late and is inconvenient to handle.
In addition, if the material to be processed passes through the heater at high speed, there is a risk of incomplete fusion, so the processing speed will inevitably be slow, and it will take time to adjust the heater temperature. In addition to not being able to quickly switch between laminating thick and thin materials, a further inconvenience is that, as shown in the figure, normal feeding rollers 20 and 20', which are not heat rollers, cannot feed the material to be processed. It is essential to use a special double-folded film in which the material R is inserted into a special film that has been folded in half in advance, and the film must be fed by a roller from the fold line. It has become difficult to use length films or individual leaf films. This is because, in the case of rolled film, etc.
Because the film is simply superimposed on the R surface of the material from above and below and is fed by rollers, no film fusion occurs at that point. As a result, the material to be processed enters the narrow gap between the opposed plate heater mechanisms 22 and 22' due to the curved film. There is a danger that the tip will get stuck at the entrance, and the polymeric film of the cut corner will be completely separated from the material R during transfer and get stuck, causing an accident that will make lamination completely impossible.

The present invention reliably eliminates the above-mentioned drawbacks of the conventional method, and by installing a heat roller mechanism at two locations, the film is adhered at the time of initial roller feeding, and is installed between the conventional rollers having the above-mentioned drawbacks. This eliminates the need for a plate-shaped heater mechanism and ensures reliable lamination through roller heating work.In addition, each heat roller mechanism part is further processed into a continuous curved plate on the outside. By attaching a thin heater cover in combination, the temperature of the heat roller part can be raised and increased in a short time with a small amount of electric power by using the composite heat of very fast heating on the thin heater cover made of plate processing, resulting in an economical energy saving. In addition to significantly shortening the work waiting time and greatly speeding up the start of work, it is possible to roll resin film by applying high-temperature heat to roller heat in two places and further fusing the film by feeding heat in the initial stage. It also makes it possible to use individual sheets of film, and to perform reliable lamination at high speeds.In addition, with two heat rollers, the temperature difference can be adjusted quickly, making lamination of thick and thin materials easy. The object of the present invention is to provide a high-speed performance laminator that can be quickly and conveniently made and can also perform single-sided lamination.An example of the implementation of the present invention will be described below with reference to the drawings. Feed hole 3 and feed hole 4 from slide parts 1 and 2 on the front and rear surfaces
A heater layer 6, located inside the roller from the front, is located on a line connecting both the holes 3, 4, and is formed into an appropriately shaped laminator case 5.
The heat rollers 7, 7', crimping finish heat rollers 8, 8', and non-heat rollers 9, 9' are sequentially installed so as to be driven by motors. Among them, a continuous curved shape that heats each of the heat rollers 7, 7', 8, 8' at a required interval on each outer side of the heat rollers 7, 7', 8, 8' It is constructed by arranging thin heater covers 10, 10', each of which has heater parts 11, 11' inside, facing each other. In the figure, 11 and 11' are the heater cover layer 1.
0 and 10' are heater parts, F and F' are wound resin films, and M is a motor.

If necessary, guide plates 12 and 13 consisting of upper and lower plates or only a lower plate may be provided at intervals between the heater cover layers 10 and 1, respectively.
0' via support plates 14 and 15, or by other suitable means. Further, it is desirable that the surface portion of each roller is made of a silicon layer 16, 16'.

Since the present invention is constructed as described above, a processing material in which rolled resin films F, F' or individual leaf resin films 23, 24 are polymerized is applied to the R surface of a material intended for laminating paperboards, etc. When the resin films 23 and 24 are fed into the feeding heat rollers 7 and 7' through the feed hole 3 of the slide section 1, the resin films 23 and 24 are fused to the R surface of the material due to the heat of the rollers, and the resin films 23 and 24 are fused to the R surface of the material. , 8', and is further heat-pressed and laminated, and is pressed by pressure-bonding feed rollers 9, 9' and sent out from the feed hole 4 of the rear slide section 2, and a reliable lamination process is performed.

In this case, by using a heat roller as the feed roller, the polymerized resin films 23 and 24 become fused to the material R at the same time as they pass there, and become adhered to the material R. Since separation does not occur, it is possible to polymerize not only individual individual films but also wound resin films F and F', and as a result of film fusion starting at the initial feeding, it is possible to finish the feeding and crimping. Coupled with the provision of the heating rollers at two locations, 7, 7', 8, and 8', the conventional plate-shaped heater mechanism with poor heating efficiency is completely unnecessary, and reliable lamination processing is ensured.

Moreover, in order to further increase the thermal efficiency of roller heating, the present invention further provides heater covers 10, 10' on the outer side of each heat roller 7, 7', 8, 8' to heat the rollers. Since the heat rollers 7, 7', 8,
The heat radiation to the outside of the cover 8' is considerably prevented, and the roller temperature is not lost, and the cover 10,1
Since 0' is a thin-walled heater related to plate processing,
Compared to a thick metal heating block mechanism, the heating rate for the roller section is significantly faster.
Combined heating can be performed on the heat roller part in a very short time, and furthermore, since the heat roller part is heated, the heat roller 7,
Since the temperature of parts 7', 8, and 8' becomes high and increases in a very short time, the waiting time for work is significantly shortened and work can be started very quickly.
The high temperature of the rollers generated by the combined heat makes it possible to transfer the material to be processed at high speed, allowing reliable lamination processing at high speeds.

In addition, since it is a composite heat source and the roller covers in the covers 10 and 10' have little heat dissipation to the outside, the working temperature can be reached quickly, and the power consumption is small, resulting in considerable power savings and energy savings. becomes. Furthermore, the heater cover 10,1
Due to the presence of 0', the resin film 23, 2 of the processing material
4 undergoes heating inside the inlet of the cover 10, 10' before reaching the feed heat rollers 7, 7', so that the fusing action at the heat rollers 7, 7' becomes very steady and Since the tip of the processed material is in the fused state U during the initial feeding,
The transition to the next press-finishing heat rollers 8, 8' is performed smoothly, and high-speed work is completely ensured.

In addition, since the heat rollers are provided at two locations, the feed and the pressure-finishing, it is possible to adjust the temperature difference between them or to adjust the temperature of the rear pressure-finishing heat roller 8.
If you switch the heater on the 8' side to high or low temperature,
It can be adapted to lamination of both thick and thin materials, and since it is a sandwiched roller heat, it can also be used for single-sided lamination.

In this way, the present invention has two heat roller mechanisms disposed in two places, and also has one heater cover.
0 and 10', the roller temperature changes from the composite heat to the cover 1 under the above action.
Combined with the prevention of heat dissipation by 0.10', the working temperature becomes high in a short period of time, which greatly reduces power consumption and contributes to energy saving, making it highly economical.Moreover, by ensuring a high temperature, work can be started quickly, and it is easy to transfer. Not only is it extremely convenient to provide a high-speed laminator that can greatly increase speed and significantly increase work efficiency, the laminating process at high speeds is completely reliable as film adhesion is performed at the time of initial rolling. Moreover, by adjusting the temperature, it is possible to quickly switch between laminating thick or thin materials, single-sided processing is also possible, and furthermore, rolled resin films F, F' and individual leaf films can be used. It is very convenient, easy to manufacture, suitable for mass production, and has many effects.
