Further, when further processing is performed, the wafer is transported to the next processing work place. Usually, this transportation is carried out by hanging a hanger in a hanging manner on an endless rail laid on the ceiling or the like for effective use of space, and placing one or a plurality of winding packages on this at the same time. A system is adopted in which the hangers are transported together to the target workplace, where only the package is lowered and the empty hangers are returned to their original positions along the endless rails.

[0003] In this case, since the hanger constantly circulates while a number of yarn processing machines such as a spinning factory and a textile factory are operating at the same time, cotton dust including lint and fly cotton may adhere to the hanger. Inevitably, cotton dust and dirt accumulated on the hanger are solidified by oil droplets from the running rail and its drive chain, etc., which peel off and drop during traveling, causing products and equipment to become dirty, etc. It becomes a problem in internal environmental management.

Further, when a plurality of winders are operating at the same time, the yarn counts and types of the packages produced for each winder may be different, so that packages of different types are alternately mixed. May be sent to the transport device one after another. In the case where such different types of packages are mixed and transported,
For each hanger, a type discriminating device for identifying and storing the type of package to be mounted on the hanger is provided, and a package of a specific type is mounted on a specific hanger having an identification memory corresponding thereto, or At the stage of placing the package on the hanger, the type information is input to the type identification device of the hanger, and when it reaches a required workplace, the type information of the type identification device is read to determine which type of package is available. It is also determined whether or not it has arrived.

[0005] In order to always maintain an accurate information transmission / transmission function, this kind discrimination device is provided with a mechanism such as being provided on the uppermost frame of a hanger so as not to be affected by the adhesion of the dust or the like as much as possible. Nevertheless, during operation for a long time, error movement and sensitivity deterioration due to adhesion of cotton dust are inevitable.

In particular, since the variety discriminating apparatus has recently been required to have a complicated and diverse information transmitting function, maintaining its accuracy, sensitivity and durability is an important issue.

The present invention seeks to solve such a problem with a simple configuration.
