Abstract

Disclosed is a dunnage apparatus, including a converting station and a deflector. The converting station converts a line of high-density supply material into low-density dunnage and ejects the dunnage at an exit in an exit trajectory along a path. The deflector is repositionable with respect to the exit between a first position, in which the deflector is interposed in the path to deflect the path of the dunnage from the exit trajectory to a first deflected trajectory, and a second position. The deflector is retained in each position during the ejection of the dunnage.

First claim

What is claimed is:

1. A dunnage apparatus, comprising:
a converting station having a housing and an exit, wherein the converting station converts a line of a supply material having a first density into dunnage having a second density, wherein the second density is less than the first density, and which converting station is configured to eject the dunnage at the exit in a first direction into an exit trajectory along a path; and
a deflector, configured for deflecting the dunnage and mounted repositionably between:
a first position at a first distance in the first direction downstream from the exit and oriented at a first angle with respect to the first direction, such that the deflector is interposed into the path of the exit trajectory to deflect the ejected dunnage traveling along the exit trajectory at an angle into a first deflected trajectory, and
a second position at a second distance in the first direction downstream from the exit and oriented at the first angle with respect to the first direction, such that the deflector is interposed into the path farther from the exit than in the first position to deflect the ejected dunnage traveling along the exit trajectory at an angle into a second deflected trajectory;

wherein the deflector is mounted with respect to the converting station such that the deflector is selectively retained in each of the first position and the second position to withstand impact by the dunnage against the deflector to maintain the direction of the first deflected trajectory and the second deflected trajectory, respectively, and
wherein the deflector is configured to be retracted at least partially to within the housing of the converting station.

2. The dunnage apparatus of claim 1 , wherein the deflector, is further repositionable to and selectively retained in a third position wherein the deflector, when in the third position, is disposed out of the path of the exit trajectory to avoid deflecting the ejected dunnage.

3. The dunnage apparatus of claim 2 , wherein the deflector, when in the third position, is retracted into the converting station housing.

4. The dunnage apparatus of claim 1 , wherein the deflector is pivotable about a pivot axis, which pivot axis is disposed at a first axis distance from the exit with the deflector in the first position, and a second axis distance from the exit with the deflector in the second position.

5. The dunnage apparatus of claim 4 , wherein the deflector comprises a hinge that defines the pivot axis, the hinge having friction that is sufficiently high to withstand a force of the ejected dunnage against the deflector to maintain a position of the deflector, yet sufficiently low to allow the deflector to be pivoted by hand between the first and second positions.

6. The dunnage apparatus of claim 4 , further comprising a track that guides the deflector between the first and second positions to reposition the pivot axis between the first and second axis distances from the exit.

7. The dunnage apparatus of claim 4 , wherein the pivot axis comprises a hinge, the hinge having sufficiently high friction to maintain a position of the deflector between the first and second positions.

8. The dunnage apparatus of claim 1 , wherein the second position is selectable from a range of second positions within a zone that extends along the exit trajectory.

9. The dunnage apparatus of claim 1 , wherein the converting station comprises opposed crumpling members that crumple the supply material to convert the supply material into the dunnage and that eject the dunnage at the exit, wherein the exit is located at said crumpling members.

10. 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.

11. The dunnage apparatus of claim 10 , wherein the cutting member is disposed upstream of the deflector with respect to the exit trajectory.

12. The dunnage apparatus of claim 10 , wherein the cutting member is disposed farther from the exit than the deflector in at least one of the first or second positions.

13. The dunnage apparatus of claim 1 , wherein the deflector is disposed in the path of the dunnage ejected at the exit such that the deflector is interposed into a top side of the path to deflect the dunnage downwards with respect to the exit trajectory of the dunnage at the exit.

14. The dunnage apparatus of claim 13 , wherein the dunnage is configured so that a container can be placed lower than the deflector and spaced therefrom, directly in one or both of the first or second deflected trajectories, such that the deflector deflects the ejected dunnage directly into the container.

15. The dunnage apparatus of claim 1 , wherein the converting station is configured to eject a continuous length of the dunnage that is longer than the each of the first and second distances.

16. The dunnage apparatus of claim 1 , wherein the converting station is configured to eject a continuous length of the dunnage that comprises a length such that the continuous length of dunnage is simultaneously being crumpled in the converting station and deflected by the deflector in each of the first and second positions.

17. A dunnage system, comprising:
the dunnage apparatus of claim 1 ; and
the supply material receivable by the converting station.

18. The dunnage system of claim 17 , wherein:
the supply material is a continuous strip of paper; and
the converting station is configured for crumpling the supply material into a continuous strip of crumpled paper.

19. A dunnage system, comprising:
the dunnage apparatus of claim 14 ; and
a container support positioned near the dunnage apparatus and lower than the exit, and configured to support a container at a container location;
wherein the deflector deflects the ejected dunnage directly into the container along the first or second deflected trajectories.

20. A method, comprising:
converting a line of supply material having a first density into dunnage having a second density, wherein the second density is less than the first density, at a converting station having a housing and an exit;
ejecting the dunnage at the exit of the converting station in a first direction into an exit trajectory along a path;
positioning and retaining a deflector mounted repositionably in a first position at a first distance in the first direction downstream from the exit and oriented at a first angle with respect to the first direction, so that the deflector is interposed into the path of the exit trajectory to deflect the ejected dunnage traveling along the exit trajectory into a first deflected trajectory; and
repositioning and retaining the deflector in a second position at a second distance in the first direction downstream from the exit and oriented at the first angle with respect to the first direction, so that the deflector is interposed into the path farther from the exit than in the first position to deflect the ejected dunnage traveling along the exit trajectory to a second deflected trajectory;
wherein the deflector is provided to be retractable at least partially to within the housing.

21. The method of claim 20 , wherein:
the converting includes crumpling paper by the converting station, such that the dunnage comprises the crumpled paper; and
the dunnage ejected from the exit has a length that is longer than a distance between the exit and the deflector com
