Abstract

A peg tray type carrier for transporting textile yarn tubes has a codable, readable and erasable electronic information carrying device such as a memory chip connected to a transmitting-receiving antenna arranged in the area of the central axis of the peg tray to achieve essentially the same effective contactless transmission interval to a compatible transmitting-receiving antenna of a reading, erasing and encoding device, which may be located for example stationarily along a peg tray transport conveyor, essentially without regard to the rotational disposition of the peg tray about its axis. Inductive, capacitive or electromagnetic forms of contactless coupling are possible for information transmission.

Claims

1. A carrier for transporting a textile yarn tube comprising a base plate, a tube supporting pin extending in upstanding relation from the base plate for telescopic insertion into a yarn tube, a selectively encodable, readable and erasable information carrying device, and a transmitting-receiving device connected to the information carrying device for communication without physical contact with a device for reading, erasing and encoding thereof having a compatible transmitting-receiving device, the base plate and the tube supporting pin defining a central axis of the tube carrier, the transmitting-receiving device for the information carrying device being disposed generally in the region of the central axis to define a generally uniform transmission interval between the transmitting-receiving device for the information carrying device and the compatible transmitting-receiving device for the reading, erasing and encoding device when disposed in proximity thereto essentially without regard to the rotational disposition of the base plate and tube supporting pin about the central axis, the information carrying device comprising a memory chip, the memory chip and the transmitting-receiving device therefor being affixed to a silicon wafer, the base plate having a substantially enclosed hollow interior area and the silicon wafer being disposed within the hollow interior area.

2. A peg tray type yarn tube carrier according to claim 1 wherein the transmitting-receiving device for the information carrying device is mounted to the base plate in a plane generally parallel to the base plate for communication with the compatible transmitting-receiving device for the reading, erasing and encoding device in a direction generally parallel to the central axis.

3. A peg tray type yarn tube carrier according to claim 1, wherein the transmitting-receiving device for the information carrying device comprises a coil having a winding arranged concentrically to the central axis to facilitate an inductive coupling of the coil with the compatible transmitting-receiving device for the reading, erasing and encoding device.
