[Industrial applications]

 The present invention relates to a metal film peeling device for a metallized plastic film. The metallized plastic film for capacitors is an ultra-thin plastic film with a metal film such as aluminum deposited on one side.However, in a capacitor using such metallized plastic film, it is not However, the cut ends of the overlapping metal film may come into contact with each other to cause a short circuit. Therefore, in order to prevent this, it may be necessary to partially peel off the deposited metal film from the plastic film.

More particularly, the present invention relates to an apparatus for stripping a metal film from a metallized plastic film in such a case.

[Prior Art]

 As shown in FIG. 1, the conventional metal film peeling apparatus includes power feeding rollers 4 and 5 on the metal film side of the metallized plastic film 3 between the work-in-process shaft 1 of the metallized plastic film material and the condenser winding shaft 2. Are further provided with winding shafts 7 and 9 and aluminum foil supply shafts 6 and 8 for winding aluminum foil through the power feeding rollers 4 and 5, respectively, and the power feeding roller 4 is connected to a cathode (or an anode) to feed power. The roller 5 is connected to a positive electrode (cathode).

Then, the power feeding rollers 4 and 5 are brought into contact with the metallized plastic film 3 traveling from the work-in-process shaft 1 to the winding shaft 2 to cause the power feeding rollers 4 and 5 to have a cathode voltage (or an anode voltage) and an anode, respectively. When a voltage (or cathode voltage) is applied, the metal film undergoes a liquefaction phenomenon of the metal due to the current load only during the application of the voltage, and the temperature rise causes a destruction phenomenon on the deposition surface between the plastic film and the metal film. The metal film peels off. The peeled metal film is transferred to the aluminum foil on the power feeding roller 5 of the attached device and wound by the winding shaft 9.

As described above, in the prior art, since the auxiliary device is provided in the metal film peeling device, the metal film peeling device is inevitably increased in size, and the peeled metal film is transferred and wound around the winding shaft 9. The aluminum foil and the aluminum foil wound on the winding shaft 7 through the power feeding roller 4 have no choice but to be discarded, which also imposes a heavy burden on the cost of the winding process.

[Problems to be solved by the device]

 An object of the present invention is to solve the above problems and provide a metal film peeling apparatus for a compact metallized plastic film.

[0007]

[Means for Solving the Problems]

 As a result of earnest research aimed at achieving this object, the inventor of the present application has found that an electrode roller for supplying an anode voltage or a cathode voltage to a metal film of a metallized plastic film running by a winder to supply an anode voltage or a cathode voltage, and the electrode roller At the position of the take-up side, it was conceived to peel the metal film by an electrode rod for applying a cathode voltage or an anodic voltage, which comes into contact with the metal film provided crossing the running direction of the metallized plastic film, and the device of the present invention. Came to invent.

The metal film peeling apparatus of the metallized plastic film of the present invention has a gap between the work-in-progress shaft of the metallized plastic film material and the condenser winding shaft on the metal film side of the metallized plastic film, An electrode rod for voltage application is provided at a right angle to the feed roller and the running direction of the plastic film, and a pressure roller is provided below the electrode rod in parallel with the electrode rod. It is a device that can move at right angles to the traveling direction and is equipped with a means for cleaning the peeled metal film residue.

The metal film peeling apparatus of the metallized plastic film of the present invention will be described in detail with reference to FIG. The metallized plastic film 13 supplied from the work-in-process shaft 11 of metallized plastic film material (provided in the direction of the arrow and not shown) is brought into contact with the power supply roller 14 and a cathode voltage (or an anode voltage) is applied to the metallized plastic film 13. After passing through the anode voltage (or cathode voltage) applying electrode rod 15 and the guide roller 16, the winding shaft 12 (provided in the direction of the arrow, not shown) is wound at intervals of.

A pressure roller 17 is provided below the voltage-applying electrode rod 15 in parallel with the electrode rod 15, and in the case of peeling, as shown in FIG. Peeling of the plastic film is not in operation, and B is in the state of peeling operation), and the running metallized plastic film 13 is pressed to bring the electrode rod 15 into contact with the plastic film and the plastic film. When an anode voltage (or a cathode voltage) is applied to the film, the metallized plastic film between the power feeding roller 14 and the electrode rod 15 has a metal film liquefaction phenomenon due to a current load on the metal film, and the plastic film is increased due to the temperature rise. A destruction phenomenon occurs on the vapor deposition surface of the film and the metal film, and the metal film is peeled off.

Since the residue of the peeled metal film is deposited on the surface of the electrode rod 15, the electrode rod 15 moves while shifting in a direction perpendicular to the running direction of the film, and the next peeling work is performed on the new surface. stand by. Residues of peeling of the metal film deposited on the electrode rod are removed by brushing or the like to obtain a fresh surface. As described above, the metal film peeling device of the metallized plastic film of the present invention is simple and compact in comparison with the conventional device, and it does not waste the use of aluminum foil, and the cost is remarkably high. You can save money.
