Apparatus for crumpling paper substrates
View Patent ↗The present subject matter relates generally to an apparatus for crumpling paper substrates. Specifically, the system provides for the crumpling of paper substrates to form fill material to be utilized in product packaging to fill void space and/or to wrap around products thereby allowing for safe transport of the products. The apparatus includes a feeder for feeding sheeting material, a first roller connected to a drive mechanism, a second roller disposed adjacent said first roller wherein said sheeting material travels between the first roller and the second roller and further wherein the second roller pushes said sheeting material against said first roller to engage the sheeting material with the first roller, and a third roller connected to the drive mechanism for directing said sheeting material out of said apparatus.
1. An apparatus for crumpling a length of sheeting material for making a cushioning product, comprising:
a first roller connected to a first drive mechanism for advancing the sheeting material along a material path;
a second roller disposed and associated adjacent said first roller for cooperatively creasing the sheeting material passing therebetween along the path for crumpling the sheeting material;
a cutting mechanism positioned downstream from the first and second roller along the material path and configured for cutting off a portion of the crumpled sheeting material; and
a third roller positioned downstream of the cutting mechanism along the material path, connected to a second drive mechanism, and driven for directing said portions out of said apparatus.
2. The apparatus of claim 1 , wherein said third roller further comprises a one-way clutch, and the second drive mechanism is connected to drive the third roller via the one-way clutch to allow the third roller to rotate in the drive direction when the second drive mechanism is inactive.
3. The apparatus of claim 1 , wherein the cutting mechanism comprises:
a cutting member configured to cut through the crumpled sheeting material; and
a protective member disposed between the cutting member and the material path and configured to shield at least a portion of said cutting member.
4. The apparatus of claim 3 , wherein the cutting member comprises a blade positioned adjacent the material path configured to cut the crumpled material and having a cutting edge shielded by the protective member.
5. The apparatus of claim 3 , wherein the protecting member is movable between a protecting position, in which it is disposed between the cutting member and the crumpled sheeting material, and a cutting position, in which the cutting member is exposed from the protective member for cutting the crumpled sheeting material.
6. The apparatus of claim 5 , wherein the protective member is biased from the cutting position toward the protecting position.
7. The apparatus of claim 6 , wherein the protective member is a resilient material that is compressible for movement from the protecting position to the cutting position.
8. The apparatus of claim 7 , wherein the first roller has a rotation axis, and the protective member is pivotally mounted for pivoting about the axis of the first roller.
9. The apparatus of claim 5 , further comprising a pusher disposed on an opposite side of the material path from the cutting member and the protective member, and is configured for moving the crumpled sheeting material against the cutting member, thereby displacing the protective member from the protective position to the cutting position and cutting the sheeting material.
10. The apparatus of claim 1 , wherein the second drive mechanism is driven by the first drive mechanism.
11. The apparatus of claim 10 , wherein the second drive mechanism comprises a belt connected to the first drive mechanism.
12. The apparatus of claim 1 , wherein the feed member is configured to form waves in the sheeting material and the first and second roller are configured to set the waves in the sheeting material in the form of creased folds.
13. An apparatus for crumpling a length of sheeting material for making a cushioning product, comprising:
a feeder for feeding sheeting material;
a first roller connected to a drive mechanism;
a second roller disposed adjacent said first roller wherein said sheeting material travels between the first roller and the second roller and further wherein the second roller pushes said sheeting material against said first roller to engage the sheeting material with the first roller; and
a third roller connected to the drive mechanism for directing said sheeting material out of said apparatus, wherein:
said third roller further comprises a clutch; and
said clutch permits said third roller to freely rotate in only one direction.
14. An apparatus for crumpling a length of sheeting material having first and second opposing faces for making a cushioning product, comprising:
a crumpling mechanism configured to crumple the sheeting material;
a cutting mechanism disposed downstream from the crumpling mechanism and configured for cutting off a portion of the crumpled sheeting material; and
an exit zone comprising a first exit roller connected to a drive mechanism configured for ejecting the portion from the apparatus and comprising a one-way clutch configured to allow the first exit roller to rotate in a drive direction when the drive mechanism is inactive.
15. The apparatus of claim 14 , wherein the cutting mechanism comprises:
a cutting member, configured to cut through the crumpled sheeting material; and
a protective member movable between a protecting position, in which it is disposed between the cutting member and the crumpled sheeting material, and a cutting position, in which the cutting member is exposed from the protective member for cutting the crumpled sheeting material.
16. The apparatus of claim 15 , wherein the crumpling mechanism defines a rotation axis and said protective member is pivotally mounted for pivoting about the rotation axis.
17. The apparatus of claim 15 , said cutting mechanism further comprising:
a pusher disposed on an opposite side of the sheeting material from the cutting member and the protective member and configured for moving the crumpled sheeting material against the cutting member, thereby displacing the protective member from the protective position to the cutting position and cutting said sheeting material.
18. The apparatus of claim 17 , wherein said cutting member is disposed within a sleeve and further wherein pushing said sheeting material with said pusher also pushes said sleeve thereby exposing the cutting member for cutting the sheeting material.
19. The apparatus of claim 14 , the exit zone further comprising an exit member arranged to cooperate with the first exit roller in ejecting the portions from the apparatus.
20. The apparatus of claim 19 , wherein the first exit roller is associated with the first face of the crumpled sheeting material and the exit member is associated with the second face of the sheeting material, the first exit roller and the exit member cooperating to guide the crumpled sheeting material out of the apparatus.
21. The apparatus of claim 20 , wherein the exit member is comprises a fourth roller disposed adjacent said third roller, the third and fourth roller associated to cooperatively eject said portion out of the apparatus.
22. The apparatus of claim 20 , wherein the exit member is a plate disposed adjacent said third roller for engaging the crumpled sheeting material against the third roller.
