11453564 · 2022-09-27 · ·

An apparatus for supplying a coil-like padding product for packaging purposes comprises a supply device for supplying a web-type padding material and also a rolling-up apparatus, which rolls up the web-type padding material to form the coil-like padding product. It is proposed that the rolling-up apparatus should comprise a flexible delimiting means, which can form an at least partially curved delimiting wall of an at least temporarily present rolling-up space, of which the extent is preferably alterable and which has an inlet for the web-type padding material, it being possible for the web-type padding material to enter into the rolling-up space through said inlet, wherein the web-type padding material is guided by the at least partially curved delimiting wall, this resulting in the formation of the coil-like padding product.

DRIVE MECHANISM FOR A PACKAGING MATERIAL WEB COILER, PACKAGING MATERIAL COILER, COILED PACKAGING MATERIAL CUSHION, AND DEVICE FOR MANUFACTURING THE SAME

A drive mechanism for a packaging material web coiler for forming a wound-up packaging material cushion may include a coiler core and a rotatable gyrating mass coupled to the coiler core. The coiled packaging material web is coilable around the coiler core such that the coiled packaging material cushion is detachable from the coiler core. With the rotatable gyrating mass, the coiler core performs at least one complete winding of the packaging material web around the coiler core in response to a manual swing-actuation.

A device for machine-making a dunnage product from a single- or multi-ply continuous paper web may include a delivery conveyor configured to draw the paper web into the device in a conveying direction; a cutter configured to separate the dunnage product from a three-dimensional strand of dunnage material formed from the paper web within the device; and a removal conveyor positioned after the cutter in the conveying direction and configured to remove the separated dunnage product from the cutter.

Crumpling mechanism for creating dunnage

A dunnage crumpling apparatus is provided having first and second entry-side crumpling members and first and second exit-side crumpling members. The first and second entry-side crumpling members define an entry therebetween. The first and second exit-side crumpling members define an exit therebetween that is disposed along the longitudinal path downstream of the entry. A crumpling zone being defined between the entry and exit. The first entry-side crumpling member is configured for moving at an first rate and is associated with the second entry-side crumpling member for moving sheet material through the entry in a first direction along a longitudinal path at an entry rate. The first exit-side crumpling member is configured for moving at an second rate and is associated with the second exit-side crumpling member for moving the sheet material through the exit in the first direction along the path at a exit rate that is slower than the entry rate to crumple the sheet material for producing dunnage. The entry and exit-side crumpling members are displaced laterally along the path with respect to each other to cause shearing of the sheet within the crumpling zone.

Dunnage system with variable accumulator

A dunnage handler for controlling the outfeed of dunnage from a dunnage machine is disclosed and can include a dunnage accumulator with first and second holding portions configured and associated with each other to define a dunnage accumulation space therebetween and for receiving and removably retaining the dunnage in the accumulation space from a dunnage machine and an articulation associating the first and second holding portions such that the holding portions are movable with respect to each other to vary the accumulation space to accommodate a varying amount of dunnage held therein, where a sensor and controller can be included to stop dunnage production when the accumulator is full.

DUNNAGE SYSTEM WITH COILER, AUTOMATED TAPING AND EJECTING APPARATUS AND METHOD
20220152970 · 2022-05-19 ·

A dunnage conversion system includes a machine for converting a stock material into a strip of relatively lower-density dunnage, a coiling mechanism for winding the strip into a coil, a taping mechanism for automatically securing a trailing end of the strip to the coil, and a coil ejecting mechanism for automatically removing the coil from the coiling mechanism. The taping mechanism includes a guide surface between an outlet of the machine and the coiling mechanism to guide the strip to the coiling mechanism and to guide tape for engagement with a trailing end of the strip and to secure the trailing end of the strip to the coil. The coil ejecting mechanism includes a lever arm that pivots to push the completed coil off the coiling mechanism.

Dunnage conversion machine and method

A dunnage conversion machine (36) converts a sheet stock material into a dunnage product that is relatively thicker and less dense than the stock material, but is relatively thin and sufficiently flexible to function as a protective wrap. The conversion machine includes a feed mechanism (40) that advances a sheet stock material therethrough and a connecting mechanism (42) downstream of the feed mechanism. The connecting mechanism retards the passage of the sheet stock material therethrough by feeding the stock material therethrough at a slower rate than the feed mechanism feeds the stock material to the connecting mechanism. This causes the stock material to randomly crumple in a longitudinal space between the feed mechanism and the connecting mechanism. The connecting mechanism connects multiple overlapping layers of sheet stock material together as they pass therethrough, including connecting at least one crumpled sheet to one side of one other sheet.

Device of providing cushioning matertal for packaging purposes

The invention relates to a device which is used to provide cushioning material for packaging purposes. The device comprises a container for storing the cushioning material and a dispensing device for dispensing the cushioning material out of the container. The dispensing device comprises a driven conveyor for conveying the cushioning material along a conveyor path, the conveyor being supported on a movable base which can be moved out of an operating position into a release position and back, said conveyor being moved out of the conveyor path in the release position.

Powered outlet chute for dunnage conversion machine
11718060 · 2023-08-08 · ·

A dunnage conversion machine that converts a stock material into a less dense dunnage product includes an outlet chute having a housing with a passage therethrough from an inlet at an inlet end downstream to an outlet at an outlet end spaced from the inlet end. The output chute includes a lower guide surface that defines a bottom side of the passage. The lower guide surface has an upstream end toward the inlet and a downstream end toward the outlet. The upstream end of the lower guide surface is spaced from a centerline of the passage a distance that is greater than a distance that the downstream end is spaced from the centerline of the passage to provide an inclined surface, such that a cross-section of the passage decreases from the inlet to the outlet.
