Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims the benefit of U.S. Application No. 62 / 880,467, filed July 30, 2019, which is incorporated herein by reference in its entirety.

[0002] FIELD OF THE INVENTION The present disclosure relates to methods and systems for producing edible structures, and more particularly to methods and systems for scoring and / or cutting edible structures prior to separating at least a portion of the edible structures. [Background technology]

[0003] Typically, the process of manufacturing and packaging edible products, such as confectionery or chewing gum, is time-consuming and involves a significant amount of equipment. For example, the process of manufacturing and packaging gum products may include mixing and producing finished gum as a non-uniform output, extruding and forming the finished gum into loaves, conditioning the loaves of finished gum, extruding the loaves into thin, continuous sheets of finished gum, rolling the continuous sheets through a series of rollers to a uniform, thin thickness, scoring and dividing the sheets into individual scored sheets, conditioning the individual sheets in a conditioning room, dividing the sheets into gum pieces, and packaging the gum pieces. Such processes for making and packaging gum products are disclosed in U.S. Patent No. 6,254,373, assigned to a joint venture involving the present assignee, and U.S. patent application Ser. No. 12 / 352,110, also assigned to the present assignee, the teachings and disclosures of which are incorporated herein by reference in their entireties to the extent not inconsistent with the present disclosure.

[0004] During the manufacturing process, the side edges of the gum are typically removed so that the outermost piece formed in the gum has the desired edge. The material trimmed or removed from the gum edges can be recycled to an upstream portion of the manufacturing system to reduce waste. As practiced in existing manufacturing systems, this trimming of material generally involves forming one or more cuts in the gum to define the portion of the gum to be trimmed. The cut gum is supported, for example, by a sliding surface or a sliding plate. However, the width of the cut gum is greater than the width of the sliding surface so that the portion of the gum to be trimmed is not directly supported by the sliding surface. As a result, gravity acting on the portion of the gum to be trimmed separates these portions at the outermost edge of the gum from the remainder of the gum along the cut line.

[0005] While this method of separating the trimmed portion of gum via gravity is suitable when the edges of the formed pieces have a planar configuration, such a method may not be suitable for trimming material along cuts that have a non-linear configuration. This may be the result of the increased length (measured in a vertical plane) over which the trimmed material must be separated from the remaining portion, and / or because gravity acting on the trimmed portion is only partially applied in the direction of separation.

[0071] [Figure 9] 9 is a cross-sectional view of the trim section of FIG. 8 taken in a plane perpendicular to the direction of travel of the gum structure according to one embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0072] The following disclosure details specific embodiments that provide improvements for separating waste portions generated during the manufacture of edible materials. Edible materials can include any type of edible product, including, but not limited to, chewing gum (at any stage, including elastomers, partially finished bases, finished chewing gum bases, and finished chewing gums), confections (which may be synonymous with chewing gum, candy, or a combination of chewing gum and candy), sweet and savory biscuits and cakes, nuts, and grains. In one embodiment, edible materials can include any edible product that is formed into a sheet during manufacture.

[0073] For ease of explanation, the edible material will be referred to herein as chewing gum for the remainder of this description. It should be further understood that certain chewing gum compositions may have a non-uniform texture and / or a multi-layered composition. The chewing gums described herein are referred to as "chewing gums" or "gums" and include, but are not limited to, compositions ranging from and including compounded elastomers to finished gums, which may include, but are not limited to, compounded elastomers with some compounding aids, masterbatch gum bases, compounded elastomers with some subsequent gum ingredients, compounded elastomers with some gum base ingredients and some subsequent gum ingredients, gum bases, gum bases with some subsequent gum ingredients, masterbatch finished gums, and finished gums.

[0074] During the chewing gum manufacturing process, one or more sections of the gum structure may be removed to form a portion of the gum structure having a desired configuration or profile. The removed gum structure sections are referred to herein as "trim sections."

[0075] An example of a gum structure 20 having one or more trim sections 22 is illustrated in more detail in FIGS. 1A and 1B. As shown, the gum structure 20 is a gum sheet having a body with a plurality of portions 24 formed therein. In the illustrated non-limiting embodiment, the plurality of portions 24 are individual pieces, and in some embodiments, pellets. The gum pellets typically have a non-uniform thickness, such as a hexagonal, pillow-shaped, or ball-like shape, and are generally coated with one or more coating materials to form a finished confection. However, it should be understood that embodiments in which the gum structure 20 has another shape, and also in which the portions 24 of the gum structure 20 have a different configuration, such as, for example, a slab or piece having a stick configuration (generally rectangular shape), are also within the scope of the present disclosure.

[0076] Adjacent portions or segments 24 formed in the gum structure 20 are generally defined by one or more score lines 26, also referred to herein as "scores." For purposes of this disclosure, a "score" may be defined as a cut that extends through the gum structure 20 to a depth less than the entire height of the gum structure 20, such that a completely separate portion of the gum structure 20 is not created. As a result, for example, a thin web 27 (best shown in FIG. 1B ) having a thickness less than 30% of the height of the gum structure 20 extends between adjacent portions or pieces 24 of the gum structure 20. When the gum structure 20 is cut or cut to a depth less than the entire height of the gum structure 20, forward movement of the gum structure 20 conveys each of the portions 24 of the gum structure 20 defined by the score 26 as a single (continuous or non-continuous) structure. Thus, when the score 26 does not extend the entire height or thickness of the gum structure 20, the gum structure 20 may move as a single unit.

[0077] One or more trim sections 22 of a gum structure 20 are typically located on the periphery of the gum structure 20. However, trim sections 22 located at other locations relative to the gum structure 20 are also contemplated herein. In the illustrated non-limiting embodiment, a first trim section 22 is defined on a first side edge 28 of the gum structure 20 and extends to an outermost edge 30 of an adjacent portion 24, specifically, a piece formed in the gum structure 20. Similarly, a second trim section 22 is located on a second side edge 32 opposite the first side edge 28 and extends to an outermost edge 30 of an adjacent portion 24 formed in the gum structure 20. The cuts defining the outermost edge 30 of a portion 24 and the trim section 22 may be referred to herein as trim cuts or trim cut lines 36. Thus, the trim cut lines 36 may have a configuration complementary to the contour of the portion 24 formed in the gum structure 20. 1A and 1B, the trim score lines 36 have a non-linear configuration. For example, the entire trim score lines 36 extending the length of the edible structure (measured along the direction of travel of the edible structure) do not lie in a single vertical plane. More specifically, the trim score lines 36 are shown having a zigzag configuration that is complementary to the contours of the pellets 24. It should be understood that trim score lines 36 having alternative configurations are also within the scope of the present disclosure.

[0078] In one embodiment, the trim score lines 36 defining one or more trim sections 22 may be formed simultaneously with the cuts 26 defining the portions or pieces 24 in the gum structure 20. In other embodiments, the trim score lines 36 defining the trim sections 22 may be formed after or downstream from the formation of the cuts 26 defining the portions or pieces 24, or alternatively, may be formed before or upstream from the formation of the cuts 26 defining the portions or pieces 24 in the gum structure 20.

[0079] The gum structure 20 is formed into a desired shape and size before the trim cuts 36 are formed therein. For example, as best shown in FIG. 2 , within a gum manufacturing system 40, a gum mass 42 may be formed into a gum structure 20 via a forming station, illustrated generally at 44. While the gum mass 42 is illustrated in the figures as being generally undefined or non-uniform, it should be understood that embodiments in which the gum mass 42 has a uniform cross-section along its length, such as obtained by extrusion through a die located upstream of the forming station 44, are also contemplated herein. The forming station 44 may include any mechanism or assembly capable of shaping and / or sizing the gum mass 42 into a gum structure 20 having a desired thickness, such as between 3 mm and 10 mm. The gum structure 20 may be sized by the forming station 44 into a sheet having generally planar upper and lower surfaces and a substantially uniform thickness prior to the formation of the trim cuts 36. In one embodiment, forming station 44 includes two forming rollers such as those described in U.S. patent application Ser. No. 13 / 522,767, filed Nov. 16, 2010. Alternatively or additionally, forming station 44 may include an extrusion device and / or one or more rolling devices. While gum structure 20 is illustrated as output from forming station 44 as a continuous sheet, embodiments in which gum structure 20 has other shapes are also within the scope of this disclosure.

[0080] 2 , in the illustrated non-limiting embodiment, the continuous gum structure 20 output from the forming station 44 is conveyed downstream by a conveying device 46, such as a conveyor, to at least one cutting or cutting device 48. The cutting or cutting device 48 is illustrated as being located directly downstream from the forming station 44. However, one or more additional system components (not shown) may be disposed between the forming station 44 and the at least one cutting or cutting device 48.

[0081] In one embodiment, the at least one cutting or cutting device 48 includes two cutting rollers 48 disposed on either side of the gum structure 20, above and below the gum structure 20, as shown in FIG. 2. However, any configuration of the one or more cutting or cutting devices 48 is contemplated herein. In another embodiment, as best shown in FIG. 3, the at least one cutting or cutting device 48 includes a first cutting ring roller 48 configured to cut the gum structure 20 in a first direction, such as parallel to the direction of travel of the gum structure, and a second roller 48 located downstream of the first cutting roller 48 and configured to cut the gum structure 20 in a second direction, such as perpendicular to the direction of travel of the gum structure 20. The cutting or cutting device 48 not only defines multiple portions 24, such as slabs or pieces, in the continuous gum structure 20, but also defines trim sections 22 of the gum structure 20. However, embodiments including a notching or cutting device 48 configured to form trim notches 36 that define one or more trim sections 22, but not form notches 26 that define multiple portions 24 in the gum structure 20, are also contemplated herein.

[0082] At least one notching or cutting device 48 is illustrated as being separate from and downstream from the forming station 44. In alternative embodiments, the functionality of one or more of the notching or cutting devices 48 may be integrated into the forming station 44 such that the forming station is operable not only to size the gum mass but also to form the trim notches 36 and / or notches 26. For example, in one embodiment, the forming station 44 includes a pair of rollers having one or more surfaces that form various portions 24 in the gum mass 42 as it passes through a gap defined between the pair of rollers. In such an embodiment, the gum mass 42 is formed to a desired size and shape and then notched to simultaneously form multiple portions or pieces 24.

[0083] 2 and 3 , the gum making system 40 may further include a trim separation system 60 operable to separate one or more trim sections 22 from the gum structure 20 by being mechanically driven, e.g., by actively applying a non-gravity force to the trim sections 22. The trim separation system 60 may be located generally downstream from one or more components (e.g., forming station 44 and / or cutting or severing devices 48) where the trim cuts 36 are formed in the gum structure 20. Thus, in some embodiments, the trim separation system 60 is located downstream from all cutting or severing devices 48, or alternatively, downstream from only a portion of the cutting or severing devices 48. Once one or more trim sections 22 have been removed from the gum structure 20, the gum structure 20 may be provided to a downstream component or system of the gum making system, such as, for example, a device operable to separate the plurality of portions 24.

[0084] An example of a trim separation system 60 is shown in more detail in Figures 4-7. As shown, the trim separation system 60 includes at least one mechanical drive device, also referred to herein as a force-generating device 62, located directly downstream from the at least one cutting or severing device 48 and operable to apply a force to a corresponding trim section 22 of the gum structure 20. As shown, a movable surface of the force-generating device may be operable to directly engage the trim section 22. In the illustrated non-limiting embodiment, the force-generating device 62 includes a roller driven about a rotational axis X. However, embodiments in which the force-generating device 62 includes a conveyor, any other suitable device, or a combination of multiple devices, such as a conveyor and a roller, are also within the scope of the present disclosure.

[0085] The force-generating device 62 may be positioned near an edge 28 or 32 of the gum structure 20, for example, in vertical alignment with at least a portion of the trim section 22. As a result, a portion of the force-generating device 62 is configured to contact the trim section 22. In other embodiments, although the force-generating device 62 is shown as being located vertically above the trim section 22, the force-generating device 62 may be disposed below the trim section 22 or adjacent to a side of the trim section 22. In one embodiment, the force-generating device 62 does not extend inwardly beyond the trim score line 36 and therefore does not overlap or contact any remaining portions of the gum structure 20.

[0086] As shown, the force generating devices 62 are mounted at an outwardly extending angle, illustrated as θ, relative to the direction of travel of the gum structure 20. In one embodiment, the angle θ is greater than 0° and less than about 90°. For example, the angle θ may be between about 5° and about 60°, between about 5° and about 45°, and between about 5° and about 30°. In embodiments in which the trim separation system 60 includes both rollers and a conveyor (see FIG. 6 ), the rollers and conveyor are generally parallel to one another. In the illustrated non-limiting embodiment, the trim separation system 60 includes a first force generating device 62 positioned adjacent a first edge 28 of the gum structure 20 and a second force generating device 62 positioned adjacent a second, opposite edge 32 of the gum structure 20 such that the trim sections 22 can be removed from the gum structure 20 substantially simultaneously. In such an embodiment, the force generating devices 62 may be mounted at equal but opposite angles relative to the direction of travel. However, embodiments in which the force-generating device 62 is mounted at a different angle are also within the scope of this disclosure.

[0087] By orienting one or more force generating devices 62 at an outward angle relative to the direction of travel of the gum structure 20, at least one component of the force applied by the force generating device 62 to the trim section 22 is applied in a breaking direction, which extends generally perpendicular to the direction of travel of the gum structure.

[0088] As the gum structure 20 passes through the trim separation system 60, one or more force-generating devices 62 engage a corresponding trim section 22. As a result of this engagement, the force-generating devices 62 exert a force on the trim section 22 that is directed generally away from the trim notch 36. The force exerted by the rollers 62 on the trim section 22 in the breaking direction applies a tension or tensile force, causing the trim section 22 to separate from the gum structure 20 along the trim notch 36. In one embodiment, the drive device 62 is movable at a speed along the direction of travel that is different from the speed of the gum structure 20. This speed difference can further increase the force exerted by the drive device 62 on the gum structure 20.

[0089] 8 and 9 , in another embodiment, the force-generating device 62 of the trim separation system 60 includes one or more compressed air delivery units that facilitate separating the trim section 22 from one or more edges of the gum structure 20. The compressed air delivery unit 62 may operate in conjunction with or independently of the one or more force-generating devices 62 previously described herein to assist in separating the trim section 22 from the gum structure 20 along the trim cut 36.

[0090] As the gum structure 20 is output from one or more scoring or cutting devices 48, compressed air from at least one compressed air delivery unit 62 is applied to the surface of the trim section 22. As shown, a compressed air delivery unit may be located proximate each of the trim sections 22. The compressed air emitted by the compressed air delivery unit 62 is used to fully separate or at least partially separate the trim sections 22 from the gum structure 20 along the trim cuts 36. As best shown in FIG. 9 , the compressed air applied to the trim sections 22 may flow in a generally vertical direction, such as vertically downward. In such an embodiment, the compressed air is applied to the top surface 23 of the trim section 22, and the resulting force generated by the application of the compressed air thereto separates the trim section 22 from the gum structure 20 along the trim cuts 36 via shear. In other embodiments, the direction of the compressed air may be oriented such that a component of the force applied by the compressed air to the surface 23 of the trim section 22 is applied in the breaking direction.

[0091] In one embodiment, regardless of the configuration of the trim separating system 60, at least one cutting or severing device 48 located directly upstream from the trim separating system 60 includes a feature 70 operable to apply a force to the trim section in a breaking direction. In one embodiment, the force applied by the feature to the trim section is used to move the trim section 22 to a desired position relative to the adjacent force-generating device 62. The feature 70 is generally located on the cutting and severing device 48 in a position that is aligned with the corresponding trim section 22. As best shown in FIG. 7 , the feature 70 is positioned adjacent an end 72 of the cutting or severing device 48 and is configured to contact the trim section 22 as the gum structure 20 traverses the cutting or severing device 48. In the illustrated non-limiting embodiment, the feature 70 includes a protrusion having a helical configuration. However, other suitable features are also within the scope of this disclosure.

[0092] As the cutting or severing device 48 rotates about its axis of rotation, a start point 74 of the feature 70 engages a portion of the trim section 22, such as near the trim score line 36. Continued rotation of the cutting or severing device 48 causes the trim section 22 to maintain contact with the feature 70. Thus, as the cutting or severing device 48 rotates about its axis of rotation, each advancing wrap of the feature 70 gradually moves the trim section 22 laterally outward in a direction generally perpendicular to the direction of advancement of the gum structure 20. The configuration of the feature 70 is selected based on the consistency of the gum and the total distance of the trim section to be moved.

[0093] It should be understood that the trim separation system 60 illustrated and described herein can be part of a continuous and / or in-line gum manufacturing system and can be placed in series with the notching or cutting device 48. The inclusion of the separation system 60 allows for continuous and rapid gum production. By using the trim separation system 60 to actively apply force to the trim section 22 to separate it from the remainder of the gum structure 20, the trim section 22 is more easily removed than with existing systems. Furthermore, by applying force thereto, the trim section 22 can be more cleanly severed from the gum structure 20, thereby limiting deformation of the gum structure 20, which is particularly beneficial during the formation of pieces or pellets 24 having irregularly shaped edges.
