Dunnage conversion machine and method with sequential stock roll storage and loading
View Patent ↗A support for one or more rolls of sheet stock material includes a sloped support surface for supporting at least one roll, an operating stop toward a lower end of the support surface that defines an operating position at which a stock roll is held for paying out sheet stock material from the roll, and a holding stop. The holding stop extends above the support surface. The holding stop holds one or more rolls at a location spaced from the operating position, and is movable to allow a stock roll to move down the support surface, past the holding stop to the operating position.
1. A support for one or more rolls of sheet stock material, comprising:
a sloped support surface for supporting at least one stock roll,
an operating stop toward a lower end of the support surface that defines an operating position on the sloped support surface at which a stock roll is held for paying out sheet stock material from the roll, and
a holding stop extending above the support surface for holding one or more rolls at a location on the sloped support surface spaced from and above the operating position, the holding stop being movable to allow a stock roll to move down the sloped support surface past the holding stop to the operating position;
wherein the holding stop is mounted to a holding arm that is pivotably movable between a holding position where the holding stop extends above the sloped surface and a release position where the holding stop drops below the sloped surface; where the support surface is defined by a pair of parallel, spaced-apart support arms that support respective opposite ends of axles extending from opposite sides of a stock roll; wherein the holding arm having a pivot axis through the pair of parallel spaced-apart support arms to pivot relative to the pair of parallel spaced-apart support arms.
2. A stock roll support as set forth in claim 1 , where the holding arm is biased toward the holding position.
3. A stock roll support as set forth in claim 1 , where the support includes a frame that supports the sloped support surface at an elevated position.
4. A stock roll support as set forth in claim 1 , where the support includes wheels, forming a mobile cart.
5. A stock roll support as set forth in claim 4 , where the cart includes a latching mechanism for coupling the cart to a dunnage conversion machine.
6. A stock roll support as set forth in claim 1 , where a cross-member with a handle connects distal ends of the holding arm.
7. A stock roll support as set forth in claim 1 , further comprising a splicing plate mounted to the stock roll support.
8. A stock roll support surface as set forth in claim 1 , in combination with a packing table having an opening therein for receiving dunnage from a conversion machine mounted below the table.
