Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film winding device suitable for use when, for example, a band-shaped film fed from an original roll is wound by a predetermined length.

[0002]

2. Description of the Related Art In recent years, a thermal transfer type video printer for printing an image recorded on a video tape on paper has been developed and put into practical use. A thermal transfer film cassette is used in such a video printer. The film cassette for heat-sensitive transfer is provided with a reel (core) rotatably supported around its axis in a casing of a predetermined shape, and this reel has a predetermined length such as 25 screens or 50 screens. The heat-sensitive transfer film is wrapped around.

This heat-sensitive transfer film is composed of one frame consisting of three frames of yellow, magenta and cyan.
An image obtained by color-separating the video image to be transferred into the above three colors is sequentially transferred by superposing one color on each frame of the above three colors.
A desired image is composed and formed.

Conventionally, when manufacturing such a film cassette for heat-sensitive transfer, a strip-shaped film wound around a material roll is unwound for a predetermined length, and a small winding operation is performed to wind it around a reel, and then, inside a casing. I was supposed to store it. At this time, each work such as a small winding operation of the film on the reel, a film cutting operation, and a sorting operation of the reels having completed the small winding operation is almost manually performed.

[0005]

However, the conventional film winding method as described above has the following problems. First, it goes without saying that in manual work, the efficiency is low, and there are problems such as variations in the winding state of the film and generation of defective products due to work mistakes. Further, if there is some defect in the film wound on the original roll, it may not be possible to secure a film of a predetermined length to be wound on the reel, which causes waste and increases the cost of defective products. There's a problem.

Further, when there are plural kinds of film lengths (number of screens) to be wound, the film winding operation becomes more troublesome and the above-mentioned problem becomes more remarkable.

The present invention has been made in consideration of the above points, and provides a film winding device capable of reducing the cost by improving the production efficiency and stabilizing the quality. With the goal.

A carrier conveyer that receives the core body from the mechanism and rotatably supports both ends thereof and conveys it, a joining material attaching mechanism that attaches a jointing material to the core body conveyed by the conveyer, and a film to be wound. A film supply mechanism that pays out toward the core that is conveyed by the conveyor, a core drive mechanism that rotates the core around its axis, and the number of rotations of the core in the core drive mechanism in advance. A control unit that determines based on the input length of the film to be wound, a film cutting mechanism that cuts the film when the film is fed out for a predetermined length, and the transport conveyor. Film Komaki apparatus characterized by comprising; and a discharge mechanism for discharging this receiving said core wrapped with the film from. 2. The film winding device according to claim 1, further comprising an inspection mechanism for inspecting a film to be supplied, wherein the length of the film supplied by the film supply mechanism is used as an inspection result by the inspection mechanism. A film winding device characterized by being configured based on the above. 3. The film winding device according to claim 1, wherein when the core driving mechanism rotates the core, the pressing roller abutting against the peripheral surface of the core has an axis line thereof. A film winding device, which is provided so as to be rotatable around.
