Abstract

A weigh-in-motion scale system for a linear synchronous motor conveyor and a method for weighing objects on a linear synchronous motor conveyor are described herein. In one embodiment, the weigh-in-motion scale system includes a support structure for supporting the following: a weigh cell, a section of a linear synchronous motor conveyor track, a vehicle for transporting an object, and an object; and a weigh cell on the support structure on which a section of a linear synchronous motor conveyor track rests directly or indirectly. In one embodiment, the method includes transporting a vehicle with an object thereon along a section of a linear synchronous motor conveyor track; and at a weighing station while the vehicle with the object thereon is being transported, weighing the section of a linear synchronous motor conveyor track, vehicle, and object to determine the weight of the object.

First claim

What is claimed is:

1. A weigh-in-motion system for weighing objects on a linear synchronous motor conveyor, wherein the linear synchronous motor conveyor includes: sections of a linear synchronous motor which motor sections include propulsion coils; a cable through which power and communication can be provided to the propulsion coils; sections of track on which a vehicle can transport an object; and at least one vehicle, said system comprising:
a. a support structure for supporting the following: a weigh cell, a section of a linear synchronous motor conveyor track, a vehicle for transporting an object, and an object; and
b. the weigh cell on said support structure on which a section of the linear synchronous motor conveyor track rests directly or indirectly, wherein said weigh cell is configured to weigh vehicles and objects while in motion; wherein the support structure is configured to also support at least one section of the linear synchronous motor, wherein the linear synchronous motor sections are positioned adjacent to one another, wherein the support structure is configured to support a section of the linear synchronous motor without supporting one or more adjacent sections of the linear synchronous motor, wherein the support structure is configured to support two sections linear synchronous motor and one section of linear synchronous motor conveyor track, and the section of the linear synchronous motor track supported by the support structure spans at least portions of the two sections of linear synchronous motor.

2. The weigh-in-motion system of claim 1 wherein the section of linear synchronous motor conveyor track and the section of the linear synchronous motor supported by the support structure are coextensive.

3. The weigh-in-motion system of claim 1 wherein the section of linear synchronous motor conveyor track and the section of the linear synchronous motor supported by the support structure each have ends that are not coextensive, wherein the section of track is shorter than the section of linear synchronous motor, wherein at least one end of said section of track terminates short of at least one end of said section of the linear synchronous motor, and a portion at the end of at least one adjacent section of track is cantilevered over the section of linear synchronous motor supported by said support structure.

4. The weigh-in-motion system of claim 1 wherein the weigh cell is an electromagnetic force restoration (EMFR) weigh cell.

5. A weigh-in-motion system for weighing objects on a linear synchronous motor conveyor, wherein the linear synchronous motor conveyor includes: sections of a linear synchronous motor which motor sections include propulsion coils; a cable through which power and communication can be provided to the propulsion coils; sections of track on which a vehicle can transport an object; and at least one vehicle, said system comprising:
a. a support structure for supporting the following: a weigh cell, a section of a linear synchronous motor conveyor track, a vehicle for transporting an object, and an object; and
b. the weigh cell on said support structure on which a section of the linear synchronous motor conveyor track rests directly or indirectly, wherein said weigh cell is configured to weigh vehicles and objects while in motion; wherein the support structure is configured to also support at least one section of the linear synchronous motor, wherein the linear synchronous motor sections are positioned adjacent to one another, wherein the support structure is configured to support a section of the linear synchronous motor without supporting one or more adjacent sections of the linear synchronous motor, wherein the section of linear synchronous motor conveyor track and the section of the linear synchronous motor supported by the support structure each have ends that are not coextensive, wherein the section of track is shorter than the section of linear synchronous motor, wherein at least one end of said section of track terminates short of at least one end of said section of the linear synchronous motor, and a portion at the end of at least one adjacent section of track is cantilevered over the section of linear synchronous motor supported by said support structure.

6. The weigh-in-motion system of claim 5 wherein the support structure is configured to support two sections linear synchronous motor and one section of linear synchronous motor conveyor track, and the section of the linear synchronous motor track supported by the support structure spans at least portions of the two sections linear synchronous motor.

7. The weigh-in-motion system of claim 5 wherein the weigh cell is an electromagnetic force restoration (EMFR) weigh cell.
