Abstract

A system for tracking items includes a turntable to receive a pallet containing articles having RFID devices, a wrap dispenser to wrap the articles with wrap as the turntable rotates and a transceiver disposed on the wrap dispenser to transmit and receive a signal from the RFID devices while the turntable is rotating and wrapping the articles. A method is provided including loading articles having RFID devices thereon on a pallet, loading the pallet on a turntable, attaching an end of a wrap to at least one of the articles, rotating the turntable to cause the wrap to encircle the articles until all of the articles are constrained in position by the wrap, transmitting a signal to the RFID devices to cause the each RFID device to emit a signal back to the transceiver, and reading the signals from the RFID devices to obtain information contained in the signals.

Claims

1. A system for tracking items, comprising:

(a) a turntable adapted to receive a pallet containing articles, said pallet and said articles having at least one RFID device thereon;

(b) a wrap dispenser configured to dispense a wrapper and to wrap the pallet containing articles with wrap as the turntable rotates, and

(c) at least one RF transceiver mounted on said dispenser adapted to transmit a signal to the at least one RFID device and receive a signal from the RFID device while said turntable is rotating and wrapping the articles.

2. The system for tracking items of claim 1, wherein the pallet has at least one RFID tag mounted thereon.

3. The system for tracking items of claim 1, wherein the each of the articles on the pallet has at least one RFID mounted thereon.

4. The system for tracking items of claim 1, wherein the wrap dispenser for wrapping the pallet and the turntable move up and down relative to one another.

5. A system for trackingitems, comprising:

(a) a turntable for receiving a plurality of articles, at least some of said plurality of articles each having an RFID device thereon;

(b) a column adjacent to the turntable for supporting a spool, the spool moveable up and down on the column, the spool having a roll of resilient film thereon;

(c) at least one RF transceiver mounted on said column, the transceiver configured to transmit a signal to transmit a signal to a plurality of RFID devices and receive return signals from the plurality of RFID devices while said turntable is rotating and wrapping the articles, each of said return signals containing data related to the articles having the RFID device thereon; and

(d) a processor for processing the data related to the articles having the RFID devices thereon.

6. The system for tracking of claim 5, wherein the spool moves up and down on the column by use of at least one electric motor.

7. The system for tracking items of claim 5, wherein the turntable is for receiving a pallet having the plurality of articles thereon.

8. The system for tracking items of claim 5, wherein the pallet has at least one RFID tag mounted thereon.

9. The system for tracking items of claim 7, wherein the each of the articles on the pallet has at least one RFID mounted thereon.

10. A method for tracking items, comprising:

(a) loading a plurality of articles on a pallet, at least one of said articles having an RFID device thereon;

(b) loading the pallet on a turntable,

(c) providing a wrap dispenser adjacent the turntable;

(d) mounting a RE transceiver on said wrap dispenser;

(e) attaching an end of a wrap to at least one of the articles or pallet;

(f) rotating the turntable to cause the wrap to encircle the articles on the pallet and continuing to rotate the turntable until substantially all of the articles are generally constrained in position by the wrap;

(g) transmitting a signal from said transceiver to the at least one RFID device to cause each RFID device to emit a signal back to the transceiver while the turntable is rotating and wrapping the articles; and

(f) reading the signal from the RFID device to obtain information contained in the signal during the wrapping operation.

11. The method for tracking items of claim 10, including moving the pallet and the transceiver up and down with respect to one another.
