  • the present invention provides a compact packaging or dunnage dispensing system and method characterized by a stack of fan-folded sheet material suitable for use as a packing material, and a support having a surface for supporting the stack. The surface has an aperture therein.
  • the system further includes a stand that supports a bottom of the support at an elevated position so that sheet material can be withdrawn from a bottom side of the stack.
  • FIGS. 1 and 2 illustrate an exemplary system 10 provided by the present invention for supporting a sheet stock material 12 and dispensing a packing material 14.
  • the packing material 14 dispensed can be a dunnage product, which typically is relatively less dense than the stock material 12.
  • the system 10 includes a supply of stock material 12 in a container 16, which protects the stock material 12 during transport and storage.
  • the walls of the container 16 also provide a surface for supporting the stock material for use as a packing material.
  • the illustrated system 10 also has a feed assembly 20 that includes at least two movable members 22 arranged for drawing sheet stock material therethrough along a linear path 24, with which an opening 26 in the container 16 can be aligned. If the feed assembly 20 imparts or reinforces a shape of the stock material drawn therethrough, the packing system 10 also can be considered a dunnage conversion system.
  • a leading end 30 of the sheet material 12 is pulled from the container 16, through the opening 26. Then the container 16 is inverted and supported above the feed assembly 20.
  • the opening 26 faces the feed assembly 20 and is aligned with the linear path 24 through the feed assembly 20.
  • the container 16 is mounted such that the rotating members 22 can engage the leading end 30 of the stock material 12 and draw the stock material 12 from the container 16.
  • the rotating members 22 draw the stock material through the feed assembly 22 and dispense the dunnage product 14.
  • the opening 26 is aligned with the feed assembly 20 and the container 16 is supported relative to the feed assembly 20.
  • Elements of the feed assembly 20 define the linear path 24 from the opening 26 through the feed assembly 20.
  • the linear path 24 through the feed assembly 20 generally is perpendicular to a plane of the opening 26 in the container 16.
  • the arrangement can be reversed, with the feed assembly supported above the stock material container.
  • feed problems such as tears or jams, and other problems sometimes related to the feeding of sheet stock material into a dunnage conversion machine, are eliminated or reduced in this arrangement.
  • this arrangement provides a very small footprint which takes up less space at a packaging workstation.
  • the stock material 12 also is completely enclosed and therefore impervious to wind or other issues that may arise in the packaging environment.
  • the feed assembly 20 is very easy to load with a new supply of stock material since the sheet material does not have to be fed around any leading rollers or feed wheels prior to drawing the sheet material from the container 16 to produce a dunnage or packing product.
  • the container 16 generally houses a stack of fan-folded sheet stock material 12 having a width dimension W s , a depth dimension D s , and a height dimension H s .
  • the width dimension W s generally is larger than a depth dimension D s of the stack 12.
  • the sheet stock material 12 includes one or more plies of sheet material, such as paper or plastic. Kraft paper is an exemplary sheet stock material.
  • the sheet stock material has fold lines 32 generally parallel to the width dimension W s .
  • the sheet stock material 12 also can be perforated or otherwise weakened along longitudinally-spaced, transversely-extending tear lines.
  • the tear lines enable or facilitate separating discrete sections of dunnage 14 from the crumpled strip exiting the feed assembly 20 (FIG. 2).
  • the tear lines generally are coextensive with the fold lines 32.
  • a cutting device can be provided to sever the strip of dunnage 14 at a desired length.
  • FIG. 4 An exemplary container 16 for a supply of stock material 12 (FIG. 3) is shown in FIG. 4.
  • the container 16 generally has a rectangular cube shape, with a height dimension H c , a width dimension W c , and a depth dimension D c orthogonal to each other.
  • the opening 26 through which the stock material 12 is drawn from the container 16 typically has a dimension that is smaller than a corresponding dimension of the container 16. In the illustrated embodiment, both the width W c and the depth D c of the container 16 are greater than the corresponding width W 0 and depth D 0 , respectively, of the opening 26.
  • the stock material 12 is drawn from the stack in a direction perpendicular to the fold lines 32, and the width of the stock material generally corresponds to the width of the stack.
  • sheet stock material, and particularly paper provides an exemplary dunnage and packing material, other forms of dunnage can be dispensed from a container or other stock material support.
  • Dunnage conversion machines that convert a supply of such stock material into a dunnage product generally have a width that is similar to the width of the stock material. Consequently, some existing dunnage conversion machines can take up a significant amount of floor space.
  • Dunnage converters also typically include a forming device at an upstream end that receives the stock material. This forming device generally is in the shape of a funnel or converging chute, with or without other complementing elements that form the stock material into a desired shape. One or more dimensions of a converging forming device decrease in a downstream direction from an inlet toward an outlet. Alternatively, the forming device can include an air bag filling and sealing assembly, for example, or other type of dunnage-forming device.
  • the outlet generally is adjacent a feed mechanism that pulls the sheet material from the supply and through the forming device.
  • the feed mechanism generally includes one or more rotating members that advance the sheet material as they rotate.
  • a disadvantage of some conversion machines is their width or the amount of space that they occupy, and in some situations it would be desirable to provide a narrower converter and a correspondingly narrow supply of stock material.
  • the present invention provides a system and method that reduce or eliminate the need to form the sheet material between the supply 12 and the feed assembly 20, thereby enabling simpler and smaller dunnage converters and dispensers.
  • employing a folded stack of sheet stock material 12, as described in more detail below enables the use of a relatively wide stock material to produce dunnage products having advantages in relatively high density and volume that otherwise generally would not be possible from a narrower stock material.
  • a typical container 16, shown in FIG. 5, is a cardboard box with one or more side walls 40 and one or more flaps 42 hingedly connected to the side walls 40.
  • One or more of these flaps 42 can be pushed inwardly to extend over the stock material therein.
  • the opening 26 therefore is defined by one or more flaps 42, and typically the flaps 42 are movable between a shipping position where the flaps 42 are generally perpendicular to the side walls 40, thereby forming a rectangular cube, and a dispensing configuration where the flaps 42 are outwardly displaced from the shipping position. In the dispensing configuration, the flaps 42 form surfaces that are inclined away from the side walls 40 of the container 16 and extend over the open side of the container 16 and the stock material in the container 16.
  • the flaps 42 of the container 16 can be configured to include features that can be used to limit the extent to which the flaps 42 can move from the dispensing position as sheet stock material is pulled through the opening 26. These features can include flaps 42 that mate with corresponding surfaces on the feed assembly 20 (as shown in FIG. 2) to prevent those flaps 42 from moving, or the flaps 42 can include tabs and slots (as shown in FIG. 4) for connecting adjacent flaps together and limiting their range of movement. Either way, when the flaps 42 are inclined they present a sloped surface to the stock material for guiding the stock material to the reduced-width outlet opening 26 and into the feed assembly 20 (FIG. 2).
  • the illustrated container 16 has a converging side wall or walls on opposing widthwise sides of the container 16 that terminate at the reduced-size outlet opening 26 through which the sheet stock material 12 is drawn. These converging walls, formed by the flaps 42, support the stock material 12 until it is pulled from the container 16. Since the opening 26 is narrower than the stock material 12, the stock material 12 is inwardly gathered and crumpled as it is pulled from the container 16. The opening 26 generally is positioned such that the stock material 12 can be drawn through the opening 26 in a direction transverse the width dimension W s of the stock material 12. The width dimension W s of the sheet stock material 12 can be
  • the container 16 can have a width dimension W c that is less than the width W s of the stack of sheet stock material 12.
  • the stack 12 has to be bent to fit within the container 16.
  • the stack is folded about an axis that is transverse the width dimension W s .
  • the resulting folded stack has a folded width dimension FW that is less than the unfolded width dimension W s , a folded height dimension FH that is greater than the unfolded height dimension H s , and a folded depth dimension FD that is the same as the unfolded depth dimension D s .
  • the container height H c , container depth D c , and container width W c generally correspond to the folded height FH, folded width FW, and folded depth FD of the folded stack 12 such that the container 16 can receive the bent folded stack.
  • the folded stack of sheet stock material 12 has a convex surface 32 and a concave surface 34 in the stack 12.
  • the bent stack is placed in the container 16 with the convex surface 32 facing the opening 26.
  • the stack 12 has been folded about a transverse axis, and in this case an axis that is perpendicular to the width dimension W s .
  • the stack 12 is folded into an inverted U-shape with the outer surface 32 of that U-shape, particularly the center of the U-shape, closest to the container opening 26.
  • the convex outer surface 32 also is the bottom surface of the stack 12.
  • the container may not include flaps and the stock material can be drawn directly into the feed assembly 20.
  • the folded stock material 12 (FIG. 7) in particular tends to inwardly gather toward a centerline as it is pulled from the stack, so very short or no converging guide surfaces are necessary.
  • sloped or converging guide surfaces are employed, they can be integrally formed in the housing for the feed assembly 20 rather than by flaps in the container 16.
  • the feed assembly 20 generally includes a housing 50 having an inlet 52 and an outlet 54, as well as an opposed pair of rotating members 22 that define a path for the sheet stock material 12 between the inlet 52 and the outlet 54.
  • the rotating members 22 can include friction wheels, gears, paddle wheels, etc.
  • the housing 50 can be shaped to support the supply of sheet stock material 12, or the supply can be supported in another way above the feed assembly 20.
  • the stock material 12 could be supported on the feed assembly 20 directly without a separate container 16.
  • the container 16 for the stock material 12, if any, preferably is integrated into the housing 50 for the feed assembly 20. Rather than replacing the container after all the stock material has been dispensed, only the stock material would need to be replaced.
  • the present invention also provides a method of dispensing a dunnage product.
  • the method includes the following steps: (i) providing a stack of fan-folded sheet stock material having fold lines parallel to a width dimension, and (ii) drawing sheet stock material from a bottom side of the stack.
  • the drawing step can include drawing the sheet stock material through an opening having a width that is less than the width of the stack.
  • the method can also include the step of pulling a leading end of the sheet stock material from the container and then inverting the container and supporting the container on the feed assembly before the drawing step.
  • the drawing step can include drawing sheet stock material from a bottom side of the stack, as is the case when the stack is supported from below and the stock material is withdrawn in a generally downward direction, as shown.
  • the drawing step is accomplished by one or more rotating members in the feed assembly, as described above.
  • the drawing step can further include pulling the stock material in a direction transverse the width dimension on a linear path through the feed assembly. Because the sheet material is drawn from the supply and through the feed assembly on a linear path, no turning of the path occurs and no turning of the stock material is necessary. Turning sheet stock material to align it with an inlet of a feed assembly generally increases friction on the stock material and can be a source of tearing of the stock material or jamming in the feed assembly. Removing the need to turn or otherwise guide the stock material to the feed assembly also provides a more compact packing system.
  • the pulling step includes moving elements of a feed assembly to pull the sheet stock material from the stack.
  • the providing step can include providing that stack of sheet material bent about an axis transverse a width dimension to form a convex surface in the stack.
  • the providing step can further include providing a container having a width dimension that is less than the width of the stock material to hold the stock material in a bent state, as shown in FIG. 6.
  • the positioning step includes positioning the stack adjacent the feed assembly, preferably supporting the stack on the feed assembly, with the opening in the container facing the feed assembly and aligned with the linear path through the feed assembly.
  • the positioning step includes pulling a leading end of the sheet material from the container and then mounting the container on the feed assembly so that the feed assembly can engage the leading end of the stock material that is supported by the feed assembly.
  • the positioning step can also include inverting the container.
  • the present invention also provides a compact packing system without a feed assembly, which makes it even simpler and more compact.

Abstract

Un système compact (10) pour la distribution d'un produit de fardage (14) comprend la combinaison d'un contenant (16) destiné à la fourniture d'une matière première en feuilles pliées en éventail (12) et d'un ensemble d'alimentation (20) permettant de tirer la matière première (12) du contenant (16). Le contenant (16) comprend une ouverture (26) présentant une dimension qui est inférieure à une dimension correspondante, en particulier une dimension de la largeur, du contenant (16). Une extrémité avant (30) du matériau en feuilles (12) est tirée depuis le contenant (16) à travers l'ouverture (26). Le contenant (16) est ensuite inversé et supporté au-dessus de l'ensemble d'alimentation (20), l'ouverture (26) faisant face à un trajet linéaire (24) et étant alignée sur celui-ci à travers l'ensemble d'alimentation (20). Le contenant (16) est supporté de sorte que des éléments rotatifs (22) dans l'ensemble d'alimentation (20) puissent mettre en prise l'extrémité avant (30) de la matière première (12) et tirer la matière première (12) du contenant (16) le long du trajet linéaire (24) et à travers l'ensemble d'alimentation (20), qui distribue le produit de fardage (14).
