Utility
Packaging system and method with controlled dunnage dispensing
6 Apr 21
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.

Utility
Dunnage conversion machine, helically-crumpled dunnage product and method
9 Mar 20
A machine for converting a sheet stock material into a relatively less dense dunnage product includes both (a) a helical pre-form assembly having a cylindrical mandrel with a longitudinal axis and a guide member for guiding the sheet stock material from a supply thereof into a helical path along and around the mandrel so as to form a helical pre-form that rotates around the longitudinal axis and advances parallel to the longitudinal axis; and (b) a restriction in the path of the pre-form that slows the advance and rotation of the pre-form past the restriction, the restriction causing the pre-form to retard longitudinal advancement, to twist upon itself, and to permanently deform as it moves past the restriction, thereby longitudinally and helically crumpling the pre-form.

Utility
Dunnage conversion machine jam-detection system and method
2 Mar 20
A jam-sensing method for a dunnage conversion machine includes the following steps: (a) converting a stock material into a relatively less dense dunnage material having characteristics that vary along the length of the dunnage material; (b) sensing the characteristics of the dunnage material; (c) generating a signal that varies as a function of the sensed characteristics; (d) monitoring the generated signal over time; and (e) generating a control signal when variation in the generated signal within a predetermined period is less than a predetermined amount, which would indicate a lack of movement of the material.

Utility
Packaging system with adjustable container closer
30 Dec 19
An improved packaging system (10) includes a packaging line that guides containers in a downstream direction, a sensor (12) that can identify a dimension of a container on the packaging line, a dunnage dispenser (14) on the packaging line downstream of the sensor to dispense dunnage to a void volume in a container, and a container closer (16) downstream of the dunnage dispenser (14) to close containers on the packaging line downstream of the dunnage dispenser.
