Description

    FIELD OF THE INVENTION
  • The present invention relates to a nip apparatus and a nip method which press a material such as a band-shaped film to be treated on a supporting member such as a roll.
    • TECHNICAL BACKGROUND
  • In a nip apparatus which a band-shaped film is conveyed while being supported on a rotating roll, when the film is provided on the roll, a part of air is enclosed in a film, the enclosed air forms air bubbles causes a partial elevation of film. The partial elevation of the film changes a gap between the film surface and a post-processing device through which the film is subjected to post-processing such as coating or plasma processing, causing problem of resulting in incapability of uniform post-processing.
  • In order to solve such a problem, there is proposed a method in which a film supported on a roll (referred to as a supporting roll) is pressed against the roll at an appropriate pressure employing a roll with elasticity (referred to as an elastic roll), thereby bringing the film into close contact with the supporting roll.
  • However, in the technique employing the elastic roll, dirt on the elastic roll surface is transferred to the film, since the elastic roll is in contact with the film. Further, the technique employing the elastic roll has problem in that since the elastic roll rotates while deforming along the outer circumference of the supporting roll, microscopic slippage takes place at the interface between the film and the elastic roll, producing scratches due to slippage on the film surface.
  • In order to prevent the dirt transfer or scratches due to slippage as described above, a technique is disclosed in, for example, Patent Document 1, in which compressed air is jetted onto a band-shaped film supported on a supporting roll, thereby improving contact between the film and the roll without employing an elastic roll.
  • A technique is disclosed in Patent Document 2 in which air present between a film and a supporting roll having numerous minute holes in the surface is sucked through the minute holes, thereby improving contact between the film and the roll.

The nozzle 16 of the take-up device 10 is disposed faced to the outer peripheral surface of the tape roll 15, and air is blown off from the nozzle 16 toward the outer peripheral surface of the tape roll 15. The nozzle 16 is fixed to a linear guide 21, and is supported movably with the tape roll 15.

A slit conditioned air nozzle opening 28a of which length is 0.7 to 1.1 times or more preferably 0.7 to 0.9 times the length in a width direction of the TAC film 11 is formed at the air nozzle 28. At the time of taking up the film, high pressure air is generated by a high pressure type blower 32 connected through an air pipe 33, and air is blown to the peripheral surface of the film roll 14 from the air nozzle opening 28a to spray air, thus removing air entering in the film roll 14 at the time of taking up the film without using the pressure roll.
    • DISCLOSURE OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION
  • However, in the technique disclosed in Patent Document 1, it is necessary that the compressed air is continuously jetted on the film surface while maintaining a pressure higher than outside atmospheric pressure and consumption of the air is too large. The technique, when expensive gas such as a nitrogen gas needs to be employed as air to be compressed, increases the gas cost, and therefore, is not considered to be useful.
  • The technique disclosed in Patent Document 2 has problem in that scratches due to edges of the numerous minute holes are produced on the surface on the side facing the roll of the film.
  • An object of the invention is to provide a nip apparatus and a nip method which reduce consumption of gas used without scratches which are produced when a material to be treated (such as a band-shaped film and the like) is pressed against a support (such as a roll and the like).
    • MEANS FOR SOLVING THE ABOVE PROBLEMS
  • The above object of the invention can be attained by a nip apparatus according to claims 1 - 3 and a method according to claim 4.
    • EFFECTS OF THE INVENTION
  • In the invention, a gas storage chamber, which stores gas with a pressure higher than outside atmospheric pressure, is disposed at a position facing a film, and a band-shaped film can be conveyed while being pressed against a roll with a reduced consumption of gas.

    PREFERRED EMBODIMENT OF THE INVENTION
  • The preferred embodiment of the invention will be explained below. The present invention will be explained employing the embodiment illustrated but the present invention is not limited thereto. A definite explanation of the preferred embodiment of the invention made below shows the best mode of the invention but does not limit the terms or technical scope described.
  • Next, the present invention will be explained, referring to the drawing.
  • Fig. 1 is a schematic drawing showing the structure of the nip apparatus 1 in the invention. In the drawing, the nip device 1 comprises a roll 3 and a gas jetting device 4, a band-shaped film 2 being supported on the roll 3 and the gas jetting device jetting gas onto the band-shaped film 2 supported on the roll 3.
  • In the gas jetting device 4, a jetting nozzle 5 as a gas introduction pipe is disposed at a position facing the film 2. A surrounding wall 6 is disposed at the tip end of the jetting nozzle 5, the surrounding wall connecting the jetting nozzle 5 and extending to the vicinity of the surface of the film 2. The surrounding wall 6 has a port diameter greater than the pipe diameter of the jetting nozzle 5, constituting a gas storage chamber 7. The gas storage chamber, which has a diameter (or a sectional area) greater than a pipe diameter (or a sectional area) of the gas introduction pipe, and is not completely opened, makes it possible to jet a high pressure gas onto an area broader than an area onto which a nozzle jets the gas, providing an excellent nip effect and reducing gas consumption amount. Namely, the nip apparatus has a structure that the stream diameter (or sectional area) of the gas stream increases in the gas storage chamber but a relatively high pressure of the gas is maintained.
  • The gas storage chamber comprises a gas jetting port and jets gas onto the film 2, whereby the film 2 can be pressed against the roll 3. Herein, the jetting nozzle 5 and the surrounding wall 6 are explained as being different members but they may be integrated into one body.
  • The roll 3 rotates in the direction as shown by an arrow Y, and the band-shaped film moves in the direction as shown by an arrow X. Gas jetted by the gas jetting device is temporarily stored in a space formed from the surrounding wall, the end surface of the jetting nozzle and the surface of the film 2. This space forms a gas storage chamber 7. Gas G , which is ejected from the gas jetting device 4 and has a pressure higher than outside atmospheric pressure, is stored in the gas storage chamber 7. The gas G with higher pressure is discharged from the gas storage chamber 7 through a gap S between the surrounding wall 6 and the film 2. The gas, G discharged from the gas storage chamber 7, accumulates in the nip apparatus 1 unless any processing is carried out, and when the accumulated gas leaks from the device, the leaked gas has problem in that it may be harmful to human body due to kinds of gas used. Accordingly, a gas discharge device 8, which sucks the gas G and discharges the gas toward a predetermined section, is provided in the vicinity of the gap S so as not to allow extra gas to accumulate in the nip apparatus 1. In this case, it is preferred that the amount of the sucked gas is larger than the jetting amount of gas jetted by the gas jetting device.
  • In the gas jetting device 4, a filter F for removing impurities in the gas G is provided in a path through which the gas G passes. In the embodiment of the invention, the filter is provided between the gas jetting device 4 and a compressor 9 which compresses the gas G In this drawing, the gas jetting device 4 is explained as pressing gas against one portion of the band-shaped film surface. Plural gas jetting device may be provided in the width direction (from the front of the page to the back of the page) of the band-shaped film 4, thereby linearly applying uniform pressure to the surface in the width direction of the film.
  • The gas jetting device can be a gas jetting device in the form of a slit capable of linearly jetting gas onto the entire surface in the width direction of the film. In this case, it is necessary that the jetting port of the gas storage chamber (the sectional area of the gas storage chamber is larger than the tip port of the slit (the sectional area of the gas introduction pipe).
  • After the film is pressed against the roll, a step may be carried out in which the pressed film is subjected to post-treatment such as coating, UV irradiation or plasma on that roll.
  • The difference in gas pressure GF (hPa) of the gas jetted by the gas jetting device 4 between the device of the invention with the gas storage chamber 7 and a conventional device without the gas storage chamber 7 was determined in the experiment. The results are shown below.
  • The experiment was carried out under the following conditions.
    S = 1mm
    W = 1000 mm
    V = 500 mm/sec.
    wherein S (mm) represents a gap between the surrounding wall 6 and the upper surface of the film 2, W (mm) represents the width of the film 2, and v (mm/sec.) represents a take-up speed at which the film 2 is taken-up.
  • The gas pressure GF was 1200 hPa in the device of the invention with the gas storage chamber 7, while the gas pressure GF was 2000 hPa in the conventional device without the gas storage chamber 7.
  • In summary, the nip apparatus of the invention with the gas storage chamber 7 enabled to convey the film 2 while pressing the film against the roll 3 without causing scratches due to film slippage at a gas pressure GF of about 1.1 times the atmospheric pressure 1013 (hPa). This shows that the gas in the gas storage chamber 7 uniformly presses the film surface.
  • In contrast, the conventional nip apparatus required a gas pressure GF of about 2 times the atmospheric pressure, in order to obtain the same performance as described above.
  • Thus, the nip apparatus of the invention comprising a gas storage chamber 7, which stores gas with a pressure higher than outside atmospheric pressure, enables to convey while pressing a band-shaped film against a roll in a reduced amount of gas.
