Amacoil Introduces Spool Flange Sensing Option
Aston, Pa.-based Amacoil Inc. now offers an optional programmable logic controller (PLC)-controlled
spool flange sensing system for use with Uhing traverse winding drives. The sensors detect the
spool flange and send a signal to a pneumatic switch, which actuates the reversal lever on the
drive. According to Amacoil, optical flange sensing saves time because less time is required to
monitor the drive's reversal points, allowing operators to manage more winding stations.
Two versions of the system are available: one in which the spool flange's diameter is programmed into the system, facilitating fast spool changeovers when all spools being used have flanges of the same diameter; and a second version that employs a two-pronged, fork-shaped fixture with a light transmitter at one end and a receiver at the other end, creating a steady beam of light or a light curtain.
Amacoil stresses that in order to optimize flange sensing effectiveness, warped spools or spools with damaged flanges should not be used, and constant reflection conditions are required. Flange sensing systems are available with new Uhing winding drive assemblies, and also may be retrofitted for use with existing Uhing setups.
