Dunnage apparatus with static remover
Provided is a dunnage apparatus, comprising a converting station and a static remover. The converting station converts a line of high-density stock material into low density dunnage and moves the dunnage along a material path in a downstream direction. The static remover is electrically grounded and contacts the dunnage to thereby remove static buildup from the material.
1. A dunnage apparatus, comprising:
a converting station that converts a line of high-density stock material into low-density dunnage and moves the dunnage along a material path; and
a static remover that is electrically grounded, that is positioned to contact the dunnage, and that is configured to remove static buildup from the dunnage upon contact therewith.
2. The dunnage apparatus of claim 1 , wherein:
the converting station comprises a frame made of conductive material; and
the static remover is electrically connected to the frame.
3. The dunnage apparatus of claim 2 , wherein the frame is electrically grounded, thereby electrically grounding the static remover.
4. The dunnage apparatus of claim 1 , wherein the static remover is electrically grounded by connecting to an earth ground.
5. The dunnage apparatus of claim 1 , wherein:
the converting station ejects the dunnage from the apparatus at an exit along the material path; and
the static remover is positioned with respect to the exit, downstream thereof, to contact and configured to discharge static from the ejected dunnage.
6. The dunnage apparatus of claim 5 , wherein the static remover is positioned to extends transversely across the material path and is angled radially towards the exit trajectory to contact the dunnage in the material path as the dunnage is ejected.
7. The dunnage apparatus of claim 5 , wherein the static remover is configured to deflect the dunnage ejected in the material path from the converting station.
8. The dunnage apparatus of claim 5 , wherein the static remover is positioned and configured to avoid interrupting the material path.
9. The dunnage apparatus of claim 5 , further comprising an exit element that defines the exit, the exit element being positioned downstream of the converting station made of non-conductive material, wherein the static remover is positioned adjacent to the exit.
10. The dunnage apparatus of claim 1 , wherein the static remover comprises a brush.
11. The dunnage apparatus of claim 10 , wherein the brush has a spine and bristles extending from the spine and into the material path.
12. The dunnage apparatus of claim 1 , further comprising a cutting member disposed downstream of the exit that severs a downstream portion of the ejected dunnage from a portion of the dunnage still held by the converting station.
13. The dunnage apparatus of claim 12 , wherein:
the converting station ejects the dunnage at an exit along the material path; and
the static remover is positioned with respect to the exit to contact and configured to discharge static from the ejected dunnage; and
the cutting member is disposed downstream of the static remover with respect to the material path, so that the static remover sufficiently removes static from a portion of the dunnage prior to the converting station moving the portion of dunnage to adjacent the cutting member.
14. The dunnage apparatus of claim 1 , further comprising a supply station that supports the stock material in a fan folded configuration prior to the stock material being pulled into the converting station.
15. The dunnage apparatus of claim 14 , wherein the converting station comprises:
an intake; and
a drive mechanism that pulls the stock material off of the supply station and through the intake, the intake being configured to constrict the path of the stock material and begin creasing the stock material into the dunnage to maintain a low-density configuration.
16. The dunnage apparatus of claim 15 , wherein the drive mechanism includes a drive roller and a pinch roller configured to compress the dunnage from the intake and crease the dunnage such that the dunnage better holds a dense configuration.
17. The dunnage conversion system of claim 15 , wherein the high-density stock material is made of paper.
18. The dunnage apparatus of claim 14 , wherein as the stock material is pulled off of the supply station, adjacent layers of the fanfold material are separated from one another, building up the static buildup.
19. The dunnage apparatus of claim 1 , wherein the converting station is electrically isolated from ground.
20. The dunnage apparatus of claim 1 , wherein the converting station is made of non-conductive material such that it does not discharge the static buildup.
21. The dunnage conversion apparatus of claim 1 , wherein the dunnage is made of a non-conductive material.
22. A dunnage conversion system, comprising:
stock material; and
the dunnage apparatus of claim 1 , wherein the dunnage apparatus crumples the material to form longitudinal crumples extending in the machine direction.
23. The dunnage conversion system of claim 22 , wherein:
the static remover comprises bristles that extend into the material path; and
the bristles are configured to be sufficiently resilient and angled such that the bristles move into and follow the longitudinal creases that are formed by the dunnage machine.
24. A method for converting dunnage, comprising:
converting a line of high-density stock material into low-density dunnage;
moving the dunnage along a material path; and
contacting the dunnage with an electrically grounded static remover to remove static buildup from the material.
