ある。Detailed Description of the Invention The present invention involves unwinding a film from an original film, printing,
In film processing equipment that has a processing section over a relatively long distance for performing processing such as drying after processing such as painting, it is provided to insert the starting end of each raw film into the processing section. This invention relates to a film threading device.

A tension detector 4 is attached to the film 5 between the plate cylinder 6 and the plate cylinder 6, and adjusts the outputs of the drive motors 3 and 7 during operation.

には一般に誘導電動機が使用されている。A film threading chain 9 driven by a drive motor 10 is provided to insert the starting end of each original film in the dryer 11 into the dryer 11, and the chain 9 is provided with a film threading bar 8. . Drive motor 10

チェーン9のバー8を折損する等の事故をもたらす。Conventionally, when threading a film, the starting end of the film is fixed at point A to the bar 8 attached to the film threading chain 9, and at point B, an operator pulls out the film from the film feeding printing section side, and the film is threaded. After accumulating a sufficient amount of water, the chain 9 was driven, and the worker manually fed the film in accordance with the movement of the chain 9, and the chain 9 carried the starting end of the film to the zero point. However, if there is a roller driven by a DC motor or the like on the feeding printing unit side, that roller becomes a load and it becomes difficult for one worker to continuously feed the film. In many cases, it is difficult to pull the film from the unwinding side using only an electric motor. It is conceivable to use the feed-out drive motor 3 or plate cylinder drive motor 7 together with the chain drive motor, but since the chain drive motor is an induction motor and its speed changes depending on the load, the chain drive motor is used as the feed-out side motor. It is difficult to operate in synchronization,
This may lead to accidents such as breakage of the bar 8 of the chain 9.

First, the application of the apparatus of the present invention to the film printing apparatus shown in FIG. 1 will be explained. The apparatus shown in FIG. 1 is a sectional drive type apparatus in which each drive section is driven by a separate motor 3.7. In this rod device, the output of each drive source is adjusted by tension control or the like. The device of FIG. 1 is equipped with a tension detector 4 for this purpose. Therefore, this tension detector 4 can be used in the device of the present invention. That is, when fixing the starting end of the film 5 to the bar 8 at point A and driving the drive motor 10 of the chain 9, the tension detector 4 detects the original film 11IIll.
The drive motor 3 of the drive portion of the film 5 is also operated at the same time, and the output of the drive motor 3 is controlled so that the detection signal of the tension detector 4 is constant. As a result, the tension of the film is stabilized regardless of variations in the output of the chain drive motor 10, that is, the speed of the chain 9, and stable film threading can be performed without the need for assistance from an operator.
フィルムの加工装置が張力検出器を備えていないときは

ができる。A control circuit for the film threading device in the apparatus shown in FIG. 1 is shown in a block diagram in FIG. Film threading start signal 1
01 is input to the motor 3 control device 104 and the motor 10 control device 105, each control device 104 and 10
5 drive motors 3 and 10, respectively. On the other hand, the detection signal value from the tension detector 4 is compared with the setting signal value from the tension setting device 103, and the motor 3 is controlled by the control device 104 so that the detection signal value from the tension detector 4 is constant. Ru. Here, if the speed of the motor 10 decreases, the tension of the film in the D section decreases and the detection signal of the detector 4 also decreases, so the motor 3 is controlled to increase the tension in the D section and the speed decreases. Furthermore, even if the speed of motor 10 increases, motor 3
is controlled. As a result, even if there is some variation in the speed of the chain drive motor, the drive motor 3 is controlled to follow the speed change, allowing continuous and stable film threading without operator assistance. It can be performed.

手動又は自動でフィルム通しストップ信号102が出力
され、両モータ3.10は停止する。When the film reaches the 0 point and the film threading is finished,
A film threading stop signal 102 is output manually or automatically, and both motors 3 and 10 are stopped.
