Film manufacturing apparatus and film manufacturing method

Abstract

To provide a film manufacturing device capable of easily manufacturing various types of sheet-like films.SOLUTION: There is provided a film manufacturing device that is configured in that: a transport mechanism 110 transports a long film; a valley fold forming mechanism 120 forms a valley fold in the film to be transported; a mountain fold forming mechanism 130 forms mountain folds in the film to be transported; a cutting mechanism 140 cuts the film with formed folds so as to obtain sheet-like films: the transport mechanism 110, the valley fold forming mechanism 120, the mountain fold forming mechanism 130 and the cutting mechanism 140 operate independently of each other; and each time the valley fold forming mechanism 120 or the mountain fold forming mechanism 130 forms a fold in the film, the transport mechanism 110 transports the film.SELECTED DRAWING: Figure 1

Claims

1. A film manufacturing apparatus for producing a single-sheet film for wrapping electrodes, A transport mechanism configured to transport long sheets of film, A valley fold forming mechanism configured to form valley folds in the film being transported, A mountain fold forming mechanism configured to form a mountain fold in the film being transported, A cutting mechanism configured to cut the film in which folds have been formed so that the aforementioned single-sheet film can be obtained, A jig having an adsorption member capable of adsorbing the aforementioned film, A pressing mechanism configured to press the film against the suction member of the jig, It has, The transport mechanism, the valley fold forming mechanism, the mountain fold forming mechanism, and the cutting mechanism operate independently of each other. Each time the valley fold forming mechanism or the mountain fold forming mechanism forms a fold in the film, the transport mechanism transports the film. The pressing mechanism presses the film against the suction member so that a predetermined position of the film after a fold has been formed but before it is cut is aligned with a predetermined position on the jig, thereby causing the film to be adsorbed onto the suction member. The cutting mechanism cuts the film while the film is adsorbed onto the adsorption member. The jig transports the sheet film obtained by cutting the film to a subsequent process while the sheet film is attached to the suction member. Film manufacturing equipment.

2. Each of the valley fold forming mechanism and the mountain fold forming mechanism forms one fold in a single fold formation process. The film manufacturing apparatus according to claim 1.

3. Between the time the valley fold forming mechanism or the mountain fold forming mechanism forms a fold in the film and the time the valley fold forming mechanism or the mountain fold forming mechanism forms the next fold in the film, the conveying mechanism conveys the film for a length corresponding to the dimensions of the sheet film to be manufactured. The film manufacturing apparatus according to claim 1.

4. A film manufacturing method for producing a single-sheet film for wrapping electrodes, A conveying process for transporting long rolls of film, A valley fold forming step in which valley folds are formed in the film being transported, A mountain fold forming step in which a mountain fold is formed in the film being conveyed, A pressing step in which the film is pressed against the suction member so that a predetermined position of the film after a fold has been formed but before it is cut is aligned with a predetermined position of the jig having a suction member capable of adsorbing the film, thereby causing the film to be adsorbed by the suction member, A cutting step is performed to cut the film, which has folds formed on it, while the film is adsorbed onto the adsorption member, in order to obtain a single sheet film. A discharge step in which the sheet film obtained by cutting the film is discharged to a subsequent process while the sheet film is adsorbed onto the adsorption member, It has, The conveying process, the valley fold formation process, the mountain fold formation process, and the cutting process are performed independently of each other. Each time a fold is formed in the film during the valley fold forming step or the mountain fold forming step, the film is transported during the transport step. Film manufacturing method.
