Description

[Detailed description of the invention] This invention uses an attached cutting blade to cut a long film such as a long film used in photoengraving or a long film base used in photolithography that is wound around a winding shaft into a desired length. The present invention relates to a cutting machine for cutting the paper into pieces.

Conventionally, a long film wound around a winding shaft (in this specification, includes the aforementioned long-wound photosensitive material, long-wound base for film mount, and long-wound aluminum foil, paper, etc.) is manually operated. To perform cutting, a tapered support shaft fixed type cutting machine 1 as shown in FIG.
Both ends of the winding shaft 3 of the winding roller 2 were applied to the tapered support shaft 4 of the cutting machine 1, and the winding roller 2 was fixed so as to be hung from both sides with the support fixing screws 5. However, when supporting the winding roller 2 at both ends, the tapered support shaft 4 and the winding shaft 3
It takes time to align the axes of the paper and adjust the tightening of the support fixing screws 5, and furthermore, when cutting the long-wrap photosensitive material in a dark room, it is impossible to visually confirm the attachment of the long-wrap photosensitive material. Therefore, it has the disadvantage that errors in cutting dimensions at both ends of the photosensitive material are likely to occur.

The present invention has been developed in view of the above-mentioned circumstances, and it is an object of the present invention to provide a cutting machine in which the take-up roller can be set at a desired location quickly and accurately.

That is, the present invention is a cutting machine for cutting a long film wound around a winding shaft into a desired length using an attached cutting blade, and the cutting machine includes a set of rotating rollers that rotate while being supported by a receiving plate. The winding roller mounting device is provided in parallel on a table, and the winding roller mounting device is provided with at least a pressing means for pressing the winding roller set on the rotating roller from the uppermost surface as necessary. This is a long film cutting machine characterized by the following.

The present invention will be explained in detail below with reference to the drawings.

FIG. 2 is a perspective view of the present invention, and FIGS. 3 and 4 are explanatory views of the structure and usage state of the present invention. In the figure, 10 indicates a take-up roller mounting device, and 11 indicates a pressing means.

As is clear from the drawing, the take-up roller mounting device 10 takes up the long film 12 on the take-up shaft 13.
It is for placing the winding roller 14 wound around the winding roller 14, and is made up of a set of rotating rollers 16 which rotate while being pivotally supported by the receiving plate 15 and are arranged in parallel on a stand 17. Therefore, this winding roller 14 can freely rotate while being supported on a set of rotating rollers 16, and when rotated in the direction of arrow 18, the long film 12 wound around the winding roller 14 is rotated.
is supplied to the cutting tool 19 provided on the table 17.

The cutting tool 19 has a structure similar to that used in this type of conventional cutting machine, and has a cutting blade 21 and a rotating roller 22 for pressing the film on the lower surface of a moving table 81 that is movably attached to a moving rail 20. is provided. Therefore, when the long film 12 is inserted between the rotary film pressing roller 22 and the table 17 and the moving table 21 is moved, the cutting blade 2 is moved.
1, the long film 12 is cut from a desired portion.

The pressing means 25 presses the winding roller 1 set on the rotating roller 16 of the winding roller mounting device 10.
4 may be of any structure as long as it can be pressed from above with appropriate pressure as necessary to prevent it from floating above the rotating roller 16. Specifically, a pressure bar 26 and a pressure bar 26 on the stand 17 are used to contact the top surface of the take-up roller 14 set on the rotating roller 16 of the take-up roller mounting device 10 and press the take-up roller 14 downward. An arm 29 is rotatably supported at one end on a support plate 27 provided on the support plate 27, and has a pressing bar 26 and a small protrusion 28 at the other end and the middle thereof, and a sliding hole 30 in which the small protrusion 28 slides. Set it in moderation,
It is comprised of an operating lever 31 whose one end is rotatably supported on the support plate 27, and an elastic member 32 that connects the small protrusion 28 and a part of the base 17. Since the pressing means 25 has such a structure, after moving the operating lever 31 and the arm 29 as shown in FIG. (See FIG. 2). After that, the operating lever 31 is lowered and the pressure bar 26, which is pivotally supported by the arm 29, is moved to the winding roller 1.
When the uppermost surface of the film 4 is pressed downward, the take-up roller 14 is supported on the rotating roller 16 and rotates freely without lifting up, allowing the long film 12 to be fed to the cutting tool 19. It can be done easily and reliably.

Next, the long film 12 is attached to a rotary film pressing roller 22 and a stand 17 provided on the lower surface of the cutting tool 19.
In between, the long film 12 is fed out until the intended cutting position reaches the cutting blade 21. The distance between the cutting blade 21 and the stand 17 is set to be greater than the thickness of the film when no pressure is applied from above the cutting tool 19, and the distance between the cutting blade 21 and the stand 17 is set so that it is in contact only when pressure is applied. After a desired amount of the film 12 has been supplied, the film can be cut by simply moving the cutting tool 19 from one end of the moving rail 20 to the other end while applying downward pressure.

In the present invention, the take-up roller device in a long film cutting machine is implemented by a take-up roller device comprising a set of rotating rollers that rotate while being supported by a receiving plate in parallel on a table. ,
The trouble of attaching and detaching is saved, and the film can be pulled out smoothly due to the two-axis rotation support, so that the work of attaching the winding roller can be carried out with good workability even if the work is done in a dark room.
