Method for automatically coiling a spool and a thread spool and coiling device for carrying out the method

摘要

The method involves inserting a coil (13) into a coil retainer of a reeling device (8), and determining residual thread on the inserted coil by using a residual thread sensor (16) i.e. light barrier sensor. The coil is wound or the coil is released only when the inserted coil carries no residual thread. A signal transmitter (17) is connected with the sensor, where the sensor is provided with a light source and a light detector. A surface of the coil is used as a reflector in a light path between the light source and the light detector. An independent claim is also included for a reeling device for executing a method for automatically winding a coil from a thread spool.
