1. Field of the Invention
The invention relates to a method and an apparatus for detecting the position of a carrier that carries a textile bobbin or cop, in the region of a work station of an automatic textile machine that has a number of work stations, wherein each work station has its own work station electronics which control the progress of work done at that work station.
In automatic textile machines, such as twisting machines, bobbin winders, etc., it is known for each work station to have its own work station electronics, which control or monitor all of the operations carried out at the applicable work station.
In order to control and monitor transport operations, such as the delivery of bobbins disposed on carriers, a common control unit belonging tobobbin winder, the cop carriers are then distributed to the various winding stations successively through shunts or the like equipped with sensor devices, and the cops are rewound onto cross-wound bobbins or cheeses. For the sake of problem-free operation at the winding stations, it is desirable for at least one reserve cop to be kept in a waiting position at the individual winding stations at all times.
An initiator for actuating the cop carrier, which is connected to the central control unit of the spinning machine and is located in the region of the waiting position, prevents the yarn joining device from making unnecessary attempts at piecing up the yarn if the reserve cop is absent.
It is also known, in a combination of a plurality of spinning and bobbin
