Furthermore, when working with insulating paper used under ultra-high pressure, such as synthetic paper, it is necessary to reduce the rotational speed to enable visual inspection, resulting in a further drop in work efficiency. Furthermore, if foreign objects are overlooked, the electrical characteristics of the cable will deteriorate, resulting in a loss of product reliability.

するにある。This invention was made in order to eliminate such drawbacks, and is an insulating paper for power cables that removes foreign matter mixed into cable insulating paper before the paper wrapping process and prevents the deterioration of the electrical characteristics of the cable due to the contamination of foreign matter. To provide a foreign object detection device.

のである。(Means and effects for solving the problems) In this invention, a laser transmission method is used as a detection method, and a He-Ne gas laser is used to inspect the entire length and width of the insulating paper.
A m@φ spot light is formed and the width direction of the insulating paper is scanned at a speed of 3000 times/second to obtain information in the width direction. In addition, a pulse generator is used to obtain information in the length direction of the insulating paper, and the information in the width direction and length direction is combined to digitally compare the size of foreign matter mixed in the insulating paper with the judgment standard. In this way, the apparatus is configured to output information on the suitability of the insulating paper to be used and its position.

In the figure, the insulating paper 2 from the original roll feeder l is
For example, it has a width of 900 am and a thickness of 0.15-1, is guided by guide rows 5 to 11, and upper blade 12
It is configured to be slit into a width of 28 mm, for example, by the lower blade 13, passed through a spacer 14, and taken up and wound into a winding washer 15 surrounded by winding under rolls 3, 3 and a presser roll 4. A laser emitter 16 is placed above the insulating paper 2 between the guide rolls 5 and 6, a pulse generator 17 is placed directly above the insulating paper 2, and a laser receiver 18 is placed below the insulating paper 2. It is arranged. Note that the outputs of the pulse generator 17 and the laser receiver 18 are respectively input to the control device a120.

The detected position of the foreign object mixed in the insulating paper 2 is calculated by combining the information in the width direction from the insulating paper 2. Further, a reference level setter 23 is connected to the control device 20, and allows setting values corresponding to the type and thickness of the insulating paper 2 to be input to the control device 20. The change in the amount of transmitted light is compared with the reference value of this preset setting value, and a judgment is made of (+) or (-), and if the level has been exceeded (
+), it is determined to be a foreign object. Further, the type and size of the foreign object is determined based on the difference from the set level, and the result is output to the printer 21 along with its position. When a foreign object is detected, an output is sent to the alarm 22 to issue an alarm, and the machine is operated.
