  • Patent number: 9370914
    Abstract: A tabletop converter has a conversion assembly that inwardly gathers and crumples a stock material to form a strip of dunnage. The conversion assembly includes a feeding assembly that moves the stock material and a controller that controls the feeding assembly to operate in both a forward direction and a reverse direction. To automatically separate a discrete dunnage product from the strip, a holder grabs and holds the strip of dunnage at a holding location downstream of the feeding assembly. The feeding assembly then operates in a reverse direction and urges the strip away from the holding location. This causes the strip to separate at or between the holding location and the feeding assembly, leaving a discrete dunnage product ready for use. The converter is mounted to a stand that allows the converter to rotate relative to part of the stand about both a horizontal axis and a vertical axis.

  • Patent number: 8997440
    Abstract: A packaging system (100) includes a controller (102), an input device (104) in communication with the controller (102) that identifies one or more characteristics of the container, an illustration with indicia representing different degrees of fill for a container; and a manual input device (106) in communication with the controller (102) for inputting an estimated degree of fullness of the packing container having one or more articles to be packed correlated with the indicia in the illustration. The controller (102) provides an output signal indicating a quantity of dunnage to dispense to the container based on the input estimated degree of fullness and the one or more identified characteristics of the container. Then the controller can determine the amount of dunnage that needs to be provided to fill the remaining void in the container, and the controller can signal a dunnage dispenser (110) to dispense the determined amount of dunnage.

    Abstract: 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.

A lower die (22) is attached to the fixed die holder plane, whereas an upper die (23) is attached to the moving die-holder plane. The moving die-holder plane is powered by an electric actuator (29) for the opening and closing movements and the half-dies are provided with heating means for the drying and hardening of the paper in a set closed position. The moving die-holder plane can be slowed down or stopped during its stroke to allow for the drying of the paper.

  • Patent number: 8425393
    Abstract: A motor-free dunnage conversion system for converting a sheet stock material into a relatively less dense dunnage includes a container having a wall with an opening therethrough, a supply of sheet stock material within the container, and a forming member. The forming member has converging sidewalls that define a passage alignable with the opening in the wall. The forming member is a converging chute having a relatively larger inlet spaced from the outlet, which is relatively smaller than the inlet. The forming member functions to crumple the sheet stock material as a packer draws the sheet stock material through the forming member to form a crumpled strip of dunnage. The forming member has a dimension that is larger than a corresponding dimension of the opening to keep the forming member from escaping the container as the packer pulls the stock material through the forming member.

  • Patent number: 8419606
    Abstract: A compact dunnage conversion machine includes a converging chute with a restricted inlet, a powered feed assembly with a sealed gearbox, a plurality of interchangeable power supplies, and a restricted outlet chute. The converter can convert a sheet stock material into dunnage for use in packaging one or more objects in a container. The restricted inlet and outlet make it more difficult for foreign objects to enter the converter and disrupt the conversion process. The sealed gearbox interposed between the driving elements of the feed assembly and an electric motor facilitates maintenance and repair of the feed assembly, while also protecting the gears therein. Finally, the power supplies provide electrical power to the motor and can include an electrical storage device, such as a battery, or an alternating-current-to-direct-current converter which is connectable to a source of electricity for supplying that electricity to the motor in an acceptable form.

  • Patent number: 8388508
    Abstract: 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.

  • Patent number: 8376114
    Abstract: A dunnage discharge chute includes features designed to prevent injury to an operator of a dunnage producing machine. The dunnage discharge chute includes at least one door with sensors that monitor the position of the door and output position signals. The position signals are received by a controller which outputs a control signal that disables operation of the dunnage producing machine based at least in part on a change in the position signals over a predetermined period of time. Additional sensors may detect whether the door is open beyond an upper open position, and a relay may disable operation of the dunnage producing machine immediately if the door is opened beyond the upper open position. Thus, if the operator reaches in through the door, the dunnage discharge chute will disable operation of the dunnage producing machine.

  • Patent number: 8360949
    Abstract: 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.

  • Publication number: 20120283084
    Abstract: A self-contained dunnage system includes a box sized to receive a supply of sheet stock material with minimal or no empty space when the box is closed. The box has one or more flaps that are movable between a generally planar closed position where the flaps cooperate to close the box and an inclined operating position displaced from the closed position. In the operating position, the ends of the flaps define a dispensing outlet spaced from an open side of the box defined by the side wall or walls of the box. The dispensing outlet is smaller than the open side of the box such that as the sheet material is pulled from the box and through the outlet, the inclined flaps act as a forming member that inwardly gathers the sheet material, causing it to crumple as it is withdrawn from the box.
