Definitions
- the herein described invention relates generally to a dunnage conversion machine and method for producing a dunnage product from sheet stock material, and more particularly, to an improved machine and method for producing a void-fill dunnage product from a sheet stock material.
- a protective packaging material is typically placed in the shipping case, or box, to fill any voids, to block, to brace and/or to cushion the article.
- packing products have been used to pack articles in shipping containers, including a crumpled paper dunnage product.
- Paper is a biodegradable and recyclable material composed of a renewable resource, making it an environmentally responsible raw material.
- conversion machines heretofore have been used to convert sheet stock material into a dunnage product. The conversion of sheet material into a crumpled dunnage product may be accomplished by a cushioning conversion machine, such as those disclosed in U.S. Patent Nos. 4,750,896; 4,884,999; and/or 5,607,383.
- Each of the cushioning conversion machines disclosed in the above-identified patents includes a conversion assembly which converts sheet stock material composed of one or more plies into a relatively less dense three-dimensional cushioning product.
- the conversion assembly includes a forming assembly which forms the sheet stock material into a strip of cushioning that is severed to form discrete pads useful as a packing material.
- cushioning conversion machines Although the cushioning conversion machines disclosed in the above- identified patents adequately perform their connecting and other functions, they generally are limited in the speed with which the cushioning product can be produced.
- cushioning products produced by cushioning conversion machines can be used as void-fill dunnage, the process of forming a cushioning product from sheet stock material generally results in a yield lower than what might otherwise be needed for use as a void-fill.
- the lower yield is caused in part by crimp loss, i.e., a loss of longitudinal length of the resulting cushioning product relative to the length of the starting sheet stock material.
- the present invention provides a dunnage conversion machine and method capable of rapidly producing a dunnage product from sheet stock material using the machine, and a dunnage product particularly useful as a void- fill dunnage product.
- a dunnage conversion machine for converting sheet stock material into a dunnage product includes a forming assembly and a feeding/fixing assembly downstream of the forming assembly.
- the feeding/fixing assembly advances sheet stock material from a supply thereof along the forming assembly, whereby the feeding/fixing assembly cooperates with the forming assembly to cause inward folding and crumpling of lateral edge portions of the sheet stock material to form a strip of dunnage having laterally spaced apart folded crumpled edge portions.
- the feeding/fixing assembly also includes laterally spaced-apart feeding/fixing members which respectively engage the folded crumpled edge portions to feed the sheet stock material through the machine and to fix the folded crumpled edge portions in a folded crumpled state.
- the forming assembly includes a chute and a former which define a path therebetween for the passage of the sheet stock material, with the former extending into the chute such that the stock material passes between the former and the chute, the former has the shape of a generally flat plate, the former has a generally triangular shape, the former is angularly adjustable relative to the chute, the former is longitudinally adjustable relative to the chute, the former is mounted to the chute, and/or the chute is a converging chute.
- a method of converting sheet stock material into a dunnage product includes: causing laterally spaced apart edge portions of the sheet stock material to fold and to crumple inwardly to form a strip of dunnage having laterally spaced apart folded crumpled edge portions; and fixing the folded crumpled edge portions in a folded crumpled state.
- causing includes feeding the sheet stock material along a forming assembly, and/or causing includes causing the laterally spaced apart edge portions to fold over a same side of the sheet stock material.
- fixing includes mechanically interlocking the layers of sheet stock material in the lateral edge portions, fixing includes perforating the layers of sheet stock material, and/or the method further includes severing dunnage products from a continuous strip of dunnage.
- a dunnage product includes n plies of sheet stock material having laterally spaced apart edge portions folded upon themselves and crumpled to form laterally spaced apart folded crumpled edge portions separated by a central portion, where n is a whole number greater than or equal to one.
- the laterally spaced apart folded crumpled edge portions are at least 2 * n layers thick and are separated by the central portion which is n layers thick
- the dunnage product is formed of multiple plies of sheet stock material
- the folded portions are of approximately equal width
- the multiple layers of sheet stock material in the folded portions are fixed to maintain the folded portions in their folded condition
- the multiple layers of sheet stock material in the folded portions are mechanically interconnected to maintain the folded portions in their folded condition
- the dunnage product further includes a plurality of perforations through the multiple layers of sheet stock material in the folded portions.
- Figure 1 is a side view of a dunnage conversion machine with a side panel of the machine's housing nearest the viewer removed to permit viewing of internal machine components.
- Figure 2 is a cross-sectional view of the machine as seen along line 2-2 of Figure 1.
- Figure 3 is an elevation view of a separating member from the machine of Figure 1.
- Figure 4 is a side view of connecting elements of the machine of Figure 1.
- Figure 5 is a sectional front view of the connecting elements shown in Figure 4 as see along line 5-5.
- Figure 6 is a perspective view of a dunnage product produced by the machine of Figure 1.
- a dunnage conversion machine 20 is illustrated.
- the machine is capable of quickly converting sheet stock material into a dunnage product that is particularly suitable for use as void-fill dunnage.
- the machine also produces a void-fill dunnage product that may have less crimp loss compared to known prior art cushioning products resulting in greater lengths of dunnage from the same length of sheet stock material.
- the sheet stock material generally consists of one or more superimposed webs or plies of kraft paper of any desired basis weight, although other types of sheet stock material may be used.
- the sheet stock material generally is tightly wrapped around a hollow core formed by a cardboard tube to form a stock roll (not shown).
- a disposable plastic plug may be inserted into each end of the tube to accommodate a difference between the inner diameter of the tube and the outer diameter of a stock roll holder, such as an axle or a spindle 22, used to support the stock roll on the conversion machine 20.
- a stock roll holder such as an axle or a spindle 22
- the machine 20 generally includes a stock supply assembly 24 at an upstream end 25 of the machine (the terms “upstream” and “downstream” are used herein in relation to the direction of flow of the stock material through the machine, from a stock inlet opening 26 at the upstream end toward an output chute 27 at a downstream end 28) that supplies the sheet stock material.
- a conversion assembly 30 is enclosed in a housing 32 downstream of the stock supply assembly 24 and converts the sheet stock material into the dunnage product.
- the stock supply assembly 24 includes a pair of laterally spaced U-shape brackets 36, a lower portion of which supports the ends of the stock roll spindle 22 supporting a stock roll (not shown), and an upper portion of which supports a constant-entry device 38 downstream of the stock roll spindle, and a separating device 40 downstream of the constant-entry device.
- the stock supply assembly 24 also may include a brake mechanism (not shown) to prevent or minimize stock roll overrun during starting and stopping of the machine 20, which causes significant variation in the amount of tension acting on the stock material being fed into the machine. The problem of overrun results from the rotational momentum of the stock roll causing the stock roll to continue rotating after the stock material is no longer being fed into the machine.
- the constant-entry device provides a substantially constant point of entry for the sheet material from the stock roll into the separating device 40 and the conversion assembly 30 regardless of the diameter of the stock roll.
- the point of entry of the stock material into the separating device remains constant. This consistency is believed to facilitate the production of a uniform dunnage product.
- a spring-biased constant-entry device (not shown) may be used.
- Such a constant-entry device additionally functions temporary as a force dampening device during a high tension situation, such as during start-up when it is necessary to overcome the starting inertia of the stock roll. Once the high tension situation is relieved, the constant-entry device automatically returns to its normal operating position which remains substantially constant as the sheet stock material is fed into the machine 20. From the constant-entry device, the sheet stock material passes to the separating device.
- the conversion assembly 30 includes a forming assembly 58 and a feeding/fixing assembly 60.
- a severing assembly 62 also is provided.
- the forming assembly is located downstream of the stock supply assembly 24 interiorly of the housing 32.
- the forming assembly as the stock material is drawn therealong, cooperates with the feeding/fixing assembly 60 to cause inward folding and crumpling of lateral edge portions of the sheet stock material to form a strip of dunnage having laterally spaced apart folded crumpled edge portions.
- the feeding/fixing assembly 60 is located downstream of the forming assembly 58 to pull or feed the sheet stock material along the forming assembly and to fix the juxtaposed multiple layers of sheet stock material in the folded portions to maintain their folded condition.
- the severing assembly 62 is mounted downstream of the feeding/fixing assembly 60 to sever discrete sections of dunnage product, such as for use as a void-fill dunnage.
- sever discrete sections of dunnage product such as for use as a void-fill dunnage.
- the forming assembly 58 is provided with a guide ramp 64 to which a shaping chute 66 is mounted, the guide ramp having an extended guide surface 68 portion extending from the downstream end of the shaping chute into close proximity to the feeding/fixing assembly 60.
- the forming assembly 58 also includes a forming member or former in the shape of a generally solid triangular plate 70 at least partially disposed within the chute 66.
- the chute has a generally flattened, hollow cone shape with a widened mouth or entranceway opening in the direction of the stock supply assembly 24 (the upstream end) with the body of the chute converging in the downstream direction toward the feeding/fixing assembly 60 and terminating in an exit.
- the chute is flattened along its vertical plane thus leading to a generally oval shape entranceway and exit.
- the triangular plate 70 is situated so as to extend into the chute with the base of the triangular plate facing the upstream end of the machine 20, and the sides of the triangular plate converging at approximately the same rate as the adjacent curved inner surfaces of the chute, with edge surfaces of the triangular plate extending into the space enclosed by the curved inner surfaces of the chute.
- the apex of the triangular plate is generally near the exit of the chute.
- the triangular plate also has rounded corners to reduce the chance for the stock material to catch and tear thereon, thereby enabling the sheet stock material to be fed through the forming assembly rapidly.
- the downstream end of the triangular plate may be flattened to give the triangular plate a trapezoidal shape.
- the triangular plate and the chute are sized relative to each other and relative to the width of the stock material so that the curved inner surfaces of the chute and the triangular plate cooperate to cause the lateral edges of the stock material passing along the forming assembly to fold inwardly upon themselves and crumple to form a continuous strip having laterally spaced apart folded crumpled edge portions.
- the triangular plate is spaced from the curved side wails and flat top wall of the chute to permit the lateral edges of the sheet stock material to crumple therebetween as it passes through the chute, thereby further increasing the thickness or loft of the folded portions.
- the spacing of the triangular plate from the bottom wall of the chute and the guide plate 64 minimizes or substantially eliminates crumpling of a central portion of the sheet stock material as it passes therebetween, providing a substantially flat central portion with less thickness than the folded portions.
- the triangular plate 70 is supported in position in the chute 66 at an intermediate point along the plate by a rod 72 which extends to a top portion of the chute, and at its upstream end, for example, by another rod 74 extending from a frame element 76 of the machine 20.
- the folded strip of dunnage passes to the feeding/fixing assembly 60 from the forming assembly 58.
- the feeding/fixing assembly 60 in the illustrated machine 20 performs two functions.
- the feeding/fixing assembly feeds the stock material through the machine, as by pulling the stock material from the stock supply assembly 24 and along the forming assembly 58.
- the feeding/fixing assembly also fixes juxtaposed layers of sheet stock material in the folded portions of the strip to maintain the three-dimensional shape of the folded portions, i.e., to keep some loft in the crumpled folded portions and to prevent or minimize unfolding of the folded portions of the dunnage product as it is manipulated.
- These dual functions are carried out by one or more pairs of feeding/fixing members, formed, for example, by rotating stitching elements such as two laterally spaced apart pairs of gear-like members 80 and 82 in the illustrated embodiment.
- the gear-like members (herein also referred to as gears) are described in greater detail in the following paragraphs.
- a lower, driven gear-like member 80 is mounted on a shaft 84 rotatably driven by a feed motor (not shown) whereas the other, opposing upper gear-like member 82, is an idler carried on a floating shaft 86.
- the driven shaft and the floating shaft are substantially parallel to each other, while both are generally perpendicular to the longitudinal dimension of the strip of dunnage (the upstream-downstream direction) and generally parallel to the width dimension of the strip of dunnage and the chute.
- the gear-like members 80 and 82 will rotate synchronously because of intermeshed segments or teeth.
- the meshing gear-like members pull the folded portions of the stock material therebetween and while doing so fix (e.g., mechanically permanently deform) the folded crumpled edge portions in a folded crumpled state.
- the then juxtaposed gear teeth will cause adjacent portions of the stock material to move in opposite directions while creating a shearing action between laterally adjacent teeth to form a slit through each one of the overlapped layers at each side of a thus formed tab portion.
- gear-like members 80 and 82 are each formed of a series of flat plates 90. This greatly facilitates production and maintenance of the gear-like members. As shown in Fig. 5, two sets of opposing gear-like members are laterally spaced on the driven and floating shafts. However, other types of feed assemblies that perform similar functions may be used, including a pair of laterally continuous rotating elements.
- gear-like members 80 and 82 or gears are illustrated in further detail in U.S. Patent No. 6,035,613 which is commonly owned with the present invention and hereby incorporated herein by reference.
- gears gear-like members
- other types of gears may be used in place of the gears described herein, such as those disclosed in commonly owned U.S. Patent No. 4,750,896, which is hereby incorporated herein in its entirety.
- the feeding/fixing assembly 60 may also include a pressure shoe 92, illustrated in Fig. 1 , biased toward the guide plate 68 between the forming assembly 58 and the gear-like members 80 and 82 to resiliently hold the central portion of the strip of dunnage and thereby help reduce jamming of the strip of dunnage as it is rapidly fed through the feeding/fixing assembly.
- the pressure shoe is formed by a leaf spring bowed in a C-shape and extending down from the frame element 76 and between the laterally spaced rotating gear-like members.
- the resilient bias of the pressure shoe can create back-pressure on the sheet stock material upstream of the pressure shoe to form undulations and/or crumpling of the central portion of the sheet material exiting the forming assembly 58.
- Other types of pressure shoes may be used in accordance with the present invention to hold and/or guide the unfolded portion of the sheet material as it passes to and/or through the feeding/fixing assembly 60.
- the stock supply assembly 24 supplies stock material to the forming assembly 58.
- the forming assembly cooperates with the feeding/fixing assembly 60 to cause inward folding and crumpling of lateral edge portions of the at least one ply sheet stock material upon themselves to form the folded crumpled portions of a continuous strip of dunnage.
- the feeding/fixing assembly 60 also advances the stock material through the machine 20 and fixes the juxtaposed layers of stock material in the folded crumpled portions.
- the severing assembly 62 severs or cuts the dunnage strip into discrete sections of a desired length.
- the crumpled and fixed folded portions provide increased column strength and stiffness in the longitudinal direction which helps feed the sheet stock material through the feeding/fixing assembly and out the output chute 27.
- the dunnage product can be produced in sections of the desired length on- demand as needed, or can be produced in batches for the delivery of a plurality of dunnage products to a packing site for use. Because the folded portions are fixed in place, the dunnage product can be handled prior without losing its shape.
- a dunnage product 100 according to the invention is schematically illustrated.
- the dunnage product comprises at least one ply of sheet stock material having lateral edge portions thereof folded over themselves as a unit to form laterally spaced apart folded portions 102.
- a central portion 104 of the dunnage product separates the folded portions and in the illustrated embodiment is relatively uncrumpled compared to the folded portions.
- Multiple layers of stock material in the folded over portions are mechanically deformed along a pair of longitudinally extending, parallel seam lines or bands to fix the juxtaposed layers of sheet stock material in place and to retain the folded portions in a folded crumpled state.
- tabs 106 have been formed from perforations in the folded portions to fix the juxtaposed layers of sheet stock material in the folded portions in place.
- the sheet stock material is biodegradable, recyclable and reusable kraft paper.
