Abstract
An alignment and task indication system is provided. The alignment and task indication system includes a conveyor cart having a first cart sensor, a second cart sensor, a first cart reflector, and a second cart reflector, and a stationary conveyor including a stationary sensor and a stationary reflector. The first cart sensor and the second cart sensor are attached to a first side of the conveyor cart and the first cart reflector and the second cart reflector are attached to a second opposite side of the conveyor cart. The first cart sensor and the first cart reflector are arranged at a first height and the second cart sensor and the second cart reflector are arranged at a second height.
Claims20
An alignment and task indication system comprising:
- a conveyor cart including a first cart sensor, a second cart sensor, a first cart reflector, and a second cart reflector, wherein the first cart sensor and the second cart sensor are attached to a first side of the conveyor cart and the first cart reflector and the second cart reflector are attached to a second opposite side of the conveyor cart, and wherein the first cart sensor and the first cart reflector are arranged at a first height and the second cart sensor and the second cart reflector are arranged at a second height;
- and
- a stationary conveyor including a stationary sensor and a stationary reflector, whereby alignment of the stationary sensor with one of the first cart reflector and the second cart reflector and simultaneous alignment of the stationary reflector with one of the first cart sensor and the second cart sensor is configured to confirm alignment between the conveyor cart and the stationary conveyor, and
- wherein the one of the first cart sensor and the second cart sensor aligned with the stationary reflector is configured to determine if the stationary conveyor is an unloading location or a loading location.
An alignment and task indication system comprising:
- a conveyor cart including a plurality of conveyor cart rollers, a first cart sensor, a second cart sensor, a first cart reflector, and a second cart reflector, wherein the first cart sensor and the second cart sensor are attached to a first side of the conveyor cart and the first cart reflector and the second cart reflector are attached to a second opposite side of the conveyor cart, and wherein the first cart sensor and the first cart reflector are arranged at a first height and the second cart sensor and the second cart reflector are arranged at a second height;
- and
- a stationary conveyor including a plurality of stationary conveyor rollers, a stationary sensor, and a stationary reflector, whereby alignment of the stationary sensor with one of the first cart reflector and the second cart reflector and simultaneous alignment of the stationary reflector with one of the first cart sensor and the second cart sensor is configured to confirm alignment between the conveyor cart and the stationary conveyor, and
- wherein the one of the first cart sensor and the second cart sensor aligned with the stationary reflector is configured to determine a rotational direction that the plurality of conveyor cart rollers and the plurality of stationary conveyor rollers rotate.
A method of operating a movable conveyor, the movable conveyor including a plurality of conveyor rollers, a first cart sensor, a second cart sensor, a first cart reflector, and a second cart reflector, the first cart sensor and the first cart reflector being arranged at a first height and the second cart sensor and the second cart reflector being arranged at a second height, the method comprising:
- moving the movable conveyor into alignment with a stationary conveyor, the stationary conveyor including a stationary sensor and a stationary reflector arranged on opposing sides thereof;
- determining which of the first cart sensor or the second cart sensor is aligned with the stationary reflector;
- upon determining that the first cart sensor is aligned with the stationary reflector, rotating the plurality of conveyor rollers in a first direction;
- and
- upon determining that the second cart sensor is aligned with the stationary reflector, rotating the plurality of conveyor rollers in a second direction.
