Extendible conveyor with irregular parcel handling
An extendible conveyor system having an extendible conveyor configured to extend into a container, at least one belt on the extendible conveyor configured to transport an irregular parcel from the container to a base end of the extendible conveyor, and a transfer mechanism configured to move the irregular parcel from the at least one belt to a shelf. A method includes transporting an irregular parcel on the at least one belt from the container to a base end of the extendible conveyor and moving the irregular parcel from the at least one belt to a shelf using the transfer mechanism.
1. An extendible conveyor system comprising:
an extendible conveyor configured to extend into a container;
at least one belt on the extendible conveyor configured to transport an irregular parcel from the container to a base end of the extendible conveyor; and
a transfer mechanism configured to move the irregular parcel from the at least one belt to a shelf,
wherein the transfer mechanism is configured to restrain the at least one belt when the irregular parcel is being moved to the shelf.
2. The extendible conveyor system of claim 1 , wherein the shelf is a takeaway conveyor.
3. The extendible conveyor system of claim 1 , further comprising a control system configured to control the at least one belt and the transfer mechanism to transport the irregular parcel from the container and onto the shelf.
4. The extendible conveyor system of claim 1 , wherein the transfer mechanism includes an elevator conveyor and at least one of: a pushbar configured to push the irregular parcel from the at least one belt and onto the elevator conveyor, a lift pushbar configured to push the irregular parcel from the elevator conveyor and onto the at least one belt, or a low-friction transfer surface disposed between the elevator conveyor and the at least one belt.
5. A method performed by an extendible conveyor system having an extendible conveyor configured to extend into a container, at least one belt on the extendible conveyor, and a transfer mechanism, comprising:
transporting an irregular parcel on the at least one belt from the container to a base end of the extendible conveyor;
moving the irregular parcel from the at least one belt to a shelf using the transfer mechanism; and
restraining the at least one belt when the irregular parcel is being moved to the shelf.
6. The method of claim 5 , wherein the shelf is a takeaway conveyor.
7. The method of claim 5 , wherein the extendible conveyor system further comprises a control system configured to control the at least one belt and the transfer mechanism.
8. The method of claim 5 , wherein the transfer mechanism includes an elevator conveyor and a pushbar configured to push the irregular parcel from the at least one belt and onto the elevator conveyor.
9. An extendible conveyor system comprising:
an extendible conveyor configured to extend into a container;
at least one belt on the extendible conveyor configured to transport an irregular parcel from the container to a base end of the extendible conveyor;
an input device configured to receive a user input that the irregular parcel is to be transported; and
an indicator configured to indicate that the irregular parcel has been transported to the base end of the extendible conveyor, for indicating that the irregular parcel must be manually transferred from the extendible conveyor.
10. The extendible conveyor system of claim 9 , further comprising a distance sensor configured to calculate an extension distance, the extension distance being the distance the extendible conveyor has extended into the container.
11. The extendible conveyor system of claim 10 , further comprising a control system configured to: use the extension distance to calculate an irregular travel distance, which is the distance the at least one belt should travel to transport the irregular parcel to the base end of the extendible conveyor; to stop the at least one belt on the extendible conveyor when the at least one belt has moved the irregular travel distance; and to activate the indicator.
12. The extendible conveyor system of claim 10 , wherein the distance sensor is one of a laser distance sensor or a proximity sensor.
13. The extendible conveyor system of claim 9 , wherein the control system is further configured to cause the at least one belt to remain stopped when the irregular parcel has been transported to the base end of the extendible conveyor until the irregular parcel has been removed from the extendible conveyor.
14. A method performed by an extendible conveyor system having an extendible conveyor configured to extend into a container and at least one belt on the extendible conveyor, comprising:
receiving a user input that an irregular parcel is to be transported,
transporting the irregular parcel on the at least one belt from the container to a base end of the extendible conveyor; and
activating an indicator when the irregular parcel has been transported the base end of the extendible conveyor, for indicating that the irregular parcel must be manually transferred from the extendible conveyor.
15. The method of claim 14 , further comprising detecting, using a distance sensor, when the irregular parcel has reached the base end of the extendible conveyor.
16. The method of claim 15 , wherein the distance sensor is one of a laser distance sensor or a proximity sensor.
17. The method of claim 14 , further comprising stopping the at least one belt when the irregular parcel has been transported to a base end of the extendible conveyor until the irregular parcel has been removed from the extendible conveyor.
18. The method of claim 14 , further comprising calculating, by a control system, when the irregular parcel will reach the base end of the extendible conveyor and stopping the at least one belt on the extendible conveyor when the irregular parcel has reached the base end of the extendible conveyor.
