The present disclosure relates to comestible manufacturing methods and systems and more particularly, to a method and system for separating at least a portion of a comestible structure after scoring and/or cutting the comestible structure.
Typically, the process of making and packaging comestibles, such as a confection or chewing gum, is time-consuming and involves a significant amount of machinery. For example, the process of making and packing gum products can include mixing and producing a finished gum as a non-uniform output, extruding and forming the finished gum into loaves, conditioning the loaves of the finished gum, extruding the loaves into a continuous thin sheet of the finished gum, rolling the continuous sheet through a series of rollers to a uniform reduced thickness, scoring and dividing sheets into individual scored sheets, conditioning the individual sheets in a conditioning room, dividing sheets into gum pieces, and packaging the gum pieces. Such processes of making and packaging gum products are disclosed in U.S. Pat. No. 6,254,373 assigned to the predecessor of interest of the present assignee, and U.S. patent application Ser. No. 12/352,110 assigned to the present assignee; the teachings and disclosures of which are hereby incorporated by reference in their entireties to the extent not inconsistent with the present disclosure.
During the manufacturing process, the lateral edges of the gum are typically removed such that the outermost pieces formed in the gum have a desired edge. The material that is trimmed or removed from the edges of the gum may be recycled back to an upstream portion of the manufacturing system to reduce waste. This trimming of material, as performed in existing manufacturing systems, generally includes forming one or more scores in the gum to define the portion of the gum to be trimmed. The scored gum is supported, such as by a sliding surface or glide plate. However, the width of the scored gum is greater than the width of the sliding surface such that the portion of the gum to be trimmed is not directly supported by the sliding surface. As a result, the gravitational forces acting on the portion of the gum to be trimmed, cause these portions at the outermost edges of the gum to separate from the remainder of the gum along the score lines.
While this method of separating the trim portions of the 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 a score having a non-linear configuration. This may be a result of the increased length (measured in a vertical plane) over which the trimmed material must be separated from the remainder and/or because the gravitational force acting on the trimmed portion is only partially applied in a direction of separation.
According to an embodiment, a method for separating a trim section from a body of comestible structure includes forming a trim score line in the body of the comestible structure to define the trim section in the body of comestible structure and actively applying a force to the trim section via a force generating device to separate the trim section from the body of comestible structure along said trim score line.

The accompanying drawings incorporated in and forming a part of the specification embodies several aspects of the present invention and, together with the description, serve to explain the principles of the invention. In the drawings:
The following disclosure will detail particular embodiments which provide improvements for separating waste portions generated during the manufacturing of a comestible. The comestible may include any type of edible product, including but not limited to chewing gum (at any stage including elastomer, partially finished base, finished chewing gum base, and finished chewing gum), confection (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 for example. In an embodiment, the comestible may include any edible product that is formed into a sheet during manufacture.
For ease of description, the comestible will be referred to herein as chewing gum for the remainder of the description. It should additionally be understood that certain compositions of chewing gum may have a non-uniform texture and/or a multi-layered composition. The chewing gum described herein is referred to as “chewing gum” or “gum” and includes, but is not limited to, compositions ranging from and inclusive of compounded elastomer to finished gum, which may include compounded elastomer in addition to some compounding aids, master batch gum base, compounded elastomer in addition to some subsequent gum ingredients, compounded elastomer in addition to some gum base ingredients and some subsequent gum ingredients, gum base, gum base in addition to some subsequent gum ingredients, master batch finished gum, and finished gum.
During a chewing gum manufacturing process, one or more sections of a gum structure may be removed to form a portion of the gum structure having a desired configuration or contour. The section of the gum structure that is removed is referred to herein as a “trim section.”
An example of a gum structure 20 having one or more trim sections 22 is illustrated in more detail in
Adjacent portions or pieces 24 formed in the gum structure 20 are generally defined by one or more score lines 26, also referred to herein as “scores.” For the 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 completely separate portions of the gum structure 20 are not created. As a result, a thin web 27, for example having a thickness of less than 30% of the height of the gum structure 20 (best shown in
One or more trim sections 22 of the gum structure 20 are typically located at an outer periphery of the gum structure 20. However, a trim section 22 located at another position relative to the gum structure 20 is also contemplated herein. In the illustrated, non-limiting embodiment, a first trim section 22 is defined at a first lateral edge 28 of the gum structure 20 and extends to the outermost edge 30 of the adjacent portions of 24, specifically the pieces formed in the gum structure 20. Similarly, a second trim section 22 is located at a second lateral edge 32, opposite the first lateral edge 28, and extends to the outermost edge 30 of the adjacent portions 24 formed in the gum structure 20. The scores that define the outermost edge 30 of the portions 24 and the trim sections 22 may be referred to herein as trim scores or trim score lines 36. Accordingly, the trim score lines 36 may have a configuration complementary to the contour of the portions 24 formed in the gum structure 20. In the illustrated, non-limiting embodiment of
In an embodiment, the trim score lines 36 that define the one or more trim sections 22 may be formed simultaneously with the scores 26 that define the portions or pieces 24 in the gum structure 20. In other embodiments, the trim score line 36 that defines a trim section 22 may be formed after or downstream from the formation of the scores 26 that define the plurality of portions or pieces 24, or alternatively, may be formed prior to or upstream from the formation of the scores 26 that define the plurality of portions or pieces 24 in the gum structure 20.
The gum structure 20 is formed into a desired shape and size prior to the formation of the trim scores 36 therein. For example, as best shown in
With continued reference to
In an embodiment, the at least one scoring or cutting device 48 includes two scoring rollers 48 disposed on opposing sides of the gum structure 20, above and below the gum structure 20, as shown in
The at least one scoring or cutting device 48 is illustrated as being located separate and downstream from the forming station 44. In an alternative embodiment, the functionality of one or more of the scoring or cutting devices 48 may be integrated into the forming station 44 such that the forming station is not only operable to size the gum mass, but also to form the trim scores 36 and/or scores 26. For example, in an 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 embodiments, the gum mass 42 is formed into a desired size and shape and scored to form a plurality of portions or pieces 24, simultaneously.
With continued reference to
An example of a trim separating system 60 is shown in more detail in
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 a trim section 22. As a result, a portion of the force generating device 62 is configured to contact the trim section 22. Although the force generating device 62 is shown being located vertically above the trim section 22, in other embodiments, the force generating device 62 may be disposed beneath the trim section 22 or adjacent a side of the trim section 22. In an embodiment, the force generating device 62 does not extend inwardly beyond the trim score line 36 and therefore does not overlap with or contact any portion of the remainder of the gum structure 20.
As shown, the force generating device 62 is mounted at an outwardly extending angle, illustrated at θ, relative to the direction of travel of the gum structure 20. In an 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 30°. In embodiments where the trim separating system 60 includes both a roller and a conveyor (see
By orienting the one or more force generating devices 62 at an outward angle relative to the direction of travel of the gum structure 20, at least a component of the force applied by the force generating device 62 to the trim section 22 is applied in a direction of breaking, which extends generally perpendicularly to the direction of travel of the gum structure.
As the gum structure 20 passes through the trim separating system 60, the one or more force generating devices 62 engage a corresponding trim section 22. As a result of this engagement, the force generating device 62 exerts a force on the trim section 22, directed generally away from the trim score 36. The force applied by the roller 62 to the trim section 22 in the direction of breaking causes the causes the trim section 22 to separate from the gum structure 20 along the trim score 36 via tension or application of a tensile force. In an embodiment, the drive device 62 is movable at a speed that is different than the speed of the gum structure 20 along the direction of travel. This difference in speed may further increase the force applied by the drive device 62 to the gum structure 20.
With reference now to
As the gum structure 20 is output from one or more scoring or cutting devices 48, compressed air from the at least one compressed air delivery unit 62 is applied to a surface of the trim section 22. As shown, the compressed air delivery units may be located proximate each of the trim sections 22. The compressed air expelled by the compressed air delivery units 62 is employed to sufficiently separate or at least partially separate the trim section 22 from the gum structure 20 along the trim score 36. As best shown in
Regardless of the configuration of the trim separating system 60, in an embodiment, the at least one scoring or cutting device 48 located directly upstream from the trim separating system 60 includes a feature 70 operable to apply a force to a trim section in the direction of breaking. In an embodiment, the force applied by the feature to the trim section is used to move a trim section 22 into a desired positioned relative to an adjacent force generating device 62. The feature 70 is generally located at the cutting and scoring device 48 at a position that is aligned with a corresponding trim section 22. As best shown in
As the scoring or cutting 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 for example. With continued rotation of the scoring or cutting device 48, the trim section 22 maintains contact with the feature 70. Accordingly, as the scoring or cutting device 48 rotates about its axis of rotation, each progressive wrap of the feature 70 gradually moves the trim section 22 laterally outward, in a direction generally perpendicular to the direction of travel of the gum structure 20. The configuration of the feature 70 is selected based on consistency of the gum and the total distance for the trim section to be moved.
It should be appreciated that the trim separating system 60 illustrated and described herein may be part of a continuous and/or in-line gum manufacturing system, and may be arranged in-line with a scoring or cutting device 48. Inclusion of the trim separating system 60 allows for continuous and expedited gum production. By using a trim separating system 60 to actively apply a force to a trim section 22 to separate the trim section 22 from the remainder of a gum structure 20, the trim section 22 is more easily removed than in existing systems. Further, via application of a force thereto, the trim section 22 may 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 that have an irregularly shaped edge.
