Processes are regulated, controlled, automated and adjusted by Novotechnik sensors. Particularly in the field of moulding injection machinery in metal-, wood-, paper- textile processing and in the packaging machinery Novotechnik sensors fulfill reliable the industry-specific requirements.
Whether a dancer application or in stroke adjustment regulations with analog or digital output signals high precision sensors from Novotechnik can be used successfully.
In injection molding machines, all values relevant to the process of manufacturing thermoplastic and duroplastic items are measured and stored. The positions of various mechanical parts are measured, as well as pressure and temperature. The goal is to achieve a consistently high quality of molded items and a short preparation time during tool changes.
Foil packaging is a practical and efficient solution to protect different products from environmental influences and damage.
The packaging machines are automatically supplied with film. In order to keep the take-off speed of the film, which can be up to 50 m/min, from the reel constant, a so-called dancer arm is used. An angle sensor is mounted in its pivot point. It determines the current position of the dancer arm and thus the constantly decreasing circumference of the reel.
In order to maintain the speed to draw off a foil consistantly, a dancer arm, which is mounted in the pivot point, is used. The Sensor Potentiometer series SP2841 in a custom design including an anti-deformation socket, cable and M12 cable box is used. The sensor signal affects the frequency converter in a way that the draw-off speed of the foil remains constant.
