Packaging system and method with controlled dunnage dispensing
View Patent ↗A packaging method includes the steps of (a) detecting whether a height ( 104 ) of contents ( 105 ) in a container ( 106 ) exceeds a predetermined height ( 112 ), and (b) indicating how much dunnage to dispense based on predetermined criteria, including whether a detected height exceeds a predetermined height that is less than a height of the container. The indicating step includes indicating a quantity of dunnage to dispense selected from a plurality of predetermined quantities of dunnage. If no detected height is greater than the predetermined height, the indicating step includes indicating that a regular amount of dunnage should be dispensed. And if a detected height is greater than the predetermined height, the indicating step includes indicating that either zero or less than the regular amount of dunnage should be dispensed. The detecting step also can include detecting whether any contents in the container have a height above the height of the container.
1. A control system for a dunnage-dispensing system that includes a dunnage dispenser, the control system comprising:
(a) a sensor that detects a height of contents in a container, and
(b) a controller connected to the sensor, the controller being configured to determine and to output a signal for a dunnage dispenser that indicates how much dunnage to dispense based on predetermined criteria, where the predetermined criteria includes a comparison between a detected height and a predetermined height that is less than a height of the container.
2. A system as set forth in claim 1 , wherein the controller includes a memory storage device containing a plurality of quantities of dunnage, and the controller indicates a quantity of dunnage to dispense that is selected from the predetermined quantities of dunnage.
3. A system as set forth in claim 2 , wherein the predetermined quantities of dunnage to dispense stored in the memory storage device include zero dunnage, a minimal amount of dunnage, and a regular amount of dunnage greater than the minimal amount.
4. A system as set forth in claim 1 , wherein the controller includes an output device for signaling when the detected height is greater than a height of the container.
5. A system as set forth in claim 1 , comprising a dunnage dispenser that is controlled by the controller.
6. A system as set forth in claim 5 , comprising a sensor that identifies a container and is connected to the controller.
