Filament production unit with a transport section, also has a camera which takes an image of the product in a monitoring zone, an analysis unit and a speed control device actuated by a signal from the analyser

摘要

A production unit (1) for continuous products (2) such as filaments or filament bundles, with a transport section (6) along which (2) moves in a direction (T), also has a monitoring system (28) which is directed to a monitoring zone (30) in the transport section (6) and produces an image (42) of this zone, an analysis unit (29) connected to the camera system which generates a control signal according to the area of (2) in the image, and a control device (38) which adjusts the speed of section (6) according to the signal. Independent claims are included for (1) a retrofit kit for monitoring (1), with a camera system (28) which produces an image of the product transported past the system (28), an analysis unit (29) as above and an interface device (37) to convert the monitoring signal into a speed signal for the production unit's motor control (38) (2) a method for controlling the production process for (2), in which a monitoring image (42) is produced and routinely updated, a representative value for the area of product (2) in the image (42) is calculated and the machine speed is adjusted according to this value .
