The present disclosure relates to an apparatus, system, and method for filling a chambered package. More particularly, the present disclosure relates to an apparatus, system, and method for automatically filling a chambered package for use in laundry and dishwashing applications.
Various types of chambered packages (e.g., unit dose packs, pods, cavity tablets, etc.) have been used for many years in the area of household care to provide a single-use, pre-dosed quantity of detergent in laundry and dishwashing applications. These types of chambered packages are generally formed from webs of film material that are in some way bonded together to form chambered recesses enclosing detergent provided within. In some of the chambered packages, different types of detergents are provided in different chambered recesses within the package to provide various cleaning effects throughout the laundry and/or dishwashing application. For example, a two chambered package may include detergent broken up into two different components: a powder component in one chambered recess and another powder, or a liquid or gel component in a second chambered recess, where only during the laundry or dishwashing application do the two components intermix. In another example, a single chambered package may include a powder detergent disposed within a single chambered recess.
Since the webs of film material are bonded together, it is desirable to ensure that the detergent be directed into the chambered recesses formed by the webs of film material so as to not interfere with the bonding therebetween. Current techniques employed to ensure that detergents, such as powdered detergents, are directed into the chambered recesses include, for example, vacuum systems configured to remove excess detergent, wiper assemblies configured to direct excess detergent into the chambered recesses, custom dispensing nozzles configured to dispense the powdered detergent into the chambered recesses, etc. However, these current techniques tend to be problematic. For example, current vacuum systems require a detailed maintenance schedule and often result in higher levels of product scrap, higher operating costs. In another example, current wiper assemblies may be unable to precisely direct the detergent into the chambered recesses which often results in increased product scrap. In addition, a complexity of current wiper assemblies often results in increased frequency of maintenance. In a still further example, custom dispensing nozzles generally require a long lead time for design and production purposes, and any design changes necessarily require additional costs, which then limit design flexibility and operational ranges.

Having thus described the disclosure in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
The present disclosure now will be described more fully hereinafter with reference to specific embodiments and particularly to the various drawings provided herewith. Indeed, the disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. As used in the specification, and in the appended claims, the singular forms “a,” “an,” “the,” include plural referents unless the context clearly dictates otherwise.
The present disclosure relates to an apparatus, system, and method for filling a chambered package. The apparatus, system, and method are utilized for directing a medium into one or more chambered recess defined about a surface of a carrying mechanism. Notably, the chambered recess defined about the surface of the carrying mechanism forms a chamber of a chambered package suitable for use in laundry and dishwashing applications. For example, the chambered package is introduced into a detergent cavity in a washing machine or a dishwasher. The chambered package is also usable in similar applications.
The carrying mechanism 102 generally refers to a device travelling in a machine direction that is configured to convey a medium in said direction. For example, the carrying mechanism may comprise a rotating drum rotating about a rotational axis and having a cylindrical surface disposed between two opposing end faces. In another example, the carrying mechanism may comprise a flatbed conveyor having a planar surface. Other example embodiments of carrying mechanisms are also contemplated.
Regardless of the type of carrying mechanism described herein, one or more chambered recess is defined about a surface thereof. Referring to
Referring to
In some example aspects, the carrying mechanism 102 may be configured to accommodate a web of film material that extends about a surface of the carrying mechanism and is received within the one or more chambered recesses 206. The web of film material may comprise a flexible, water soluble film material, such as a sheet-like flexible plastic formed of, for example, cellophane, polyethylene, acetates, polyvinyl alcohol (PVA), or the like, that is capable of having individual chambers formed therein, of being sealed and folded, bonded etc. In some aspects, a forming arrangement (e.g., a vacuum) is configured to interact with the web of film material. More particularly, for example, the forming arrangement is configured to exert a negative pressure through each of the one or more platen 204 or through the surface of the carrying mechanism so as to draw the web of film material into the one or more chambered recesses. As such, the carrying mechanism provides one or more chambered recess having a web of film material drawn into a bottom thereof, in which a quantity of medium may be dispensed.
Returning back to
The second end 306 of the dispensing nozzle 300 is configured to dispense the quantity of the medium received from the first end 304 through the longitudinal opening 302 and out of the second end into the one or more chambered recess defined about a surface of a carrying mechanism. In some example implementations, the second end of the dispensing nozzle is fixedly attached to the longitudinal opening, while in other example implementations; the second end of the dispensing nozzle is movably attached to the longitudinal opening.
The second end 306 of the dispensing nozzle 300 is also angled relative to a perpendicular of a machine direction of a carrying mechanism. More particularly, the second end of the dispensing nozzle may be angled between about 20 degrees and about 80 degrees relative to the perpendicular of the machine direction of the carrying mechanism; preferably between about 40 degrees and about 70 degrees; and most preferably about 60 degrees relative to the perpendicular of the machine direction. In this manner, the second end of the dispensing nozzle being angled about 60 degrees relative to the perpendicular is considered most advantageous in effectively directing a medium into a chambered recess defined about a surface of a carrying medium traveling in a machine direction.
In some example implementations, the second end 306 of the dispensing nozzle 300 is disposed adjacent to a carrying mechanism traveling in the machine direction.
Further, where the carrying mechanism is a rotating drum, such as the rotating drum 400, the second end 306 of the dispensing nozzle 300 may be disposed adjacent to the rotating drum between about 10 degrees and about 95 degrees relative to a center (i.e., a horizontal axis bisecting a center point) of the rotating drum. More particularly,
While not illustrated in
Referring back to
The dispensing apparatus 104 further comprises at least one wiping material.
As illustrated in
In another example implementation, rather than a single wiping material being arranged so as to define an angle having a vertex, at least two wiping materials may be convergingly arranged towards the machine direction. For example, two wiping materials may be arranged to form a 30 degree angle having a vertex toward the machine direction. In another example, there may be three concentrically arranged sets of two wiping materials, each set of two wiping materials defining an angle having a vertex toward the machine direction about the bottom surface of the housing, each angle being about 30 degrees.
Accordingly, the angle of the at least one wiping material 500 is configured to direct any of the quantity of the medium dispensed out of the second end 306 of the dispensing nozzle 300, but not directed into the one or more chambered recess, into the one or more chambered recess during travel of the carrying mechanism in the machine direction. More particularly, any of the quantity of the medium remaining on the surface of the carrying mechanism may be entrapped between the wiping material and the surface of the carrying mechanism and directed into the one or more chambered recess as the carrying mechanism travels in the machine direction.
Returning back to
Furthermore, the second end 306 of the dispensing nozzle 300 may comprise a resilient material 314 configured to directly interact with the carrying mechanism in order to direct the quantity of the medium into the one or more chambered recess defined about the surface of the carrying mechanism. More particularly, the resilient material may include a same or similar material to the at least one wiping material 500, such as an EPDM rubber, such that the resilient material is configured to directly interact or touch the surface of the carrying material. Otherwise, the resilient material may include a material different than the at least one wiping material.
Advantageously, in order to direct the quantity of medium remaining on the surface, the second end 306 of the dispensing nozzle 300 and the bottom surface 310 of the housing 308, each adjacent to the surface of the carrying mechanism, may each be contoured to match a contour of the surface of the carrying mechanism. Likewise, the tongue 312 may be contoured to match a contour of the surface of the carrying mechanism. For example, where the carrying mechanism is a rotating drum, each of the second end of the dispensing nozzle, the bottom surface of the housing, and the tongue may comprise a curved contour that matches the cylindrical curvature of the contour of the cylindrical surface of the rotating drum.
Returning back to
The method further comprises directing, by at least one wiping material that is arranged to define an angle having a vertex toward the machine direction about a bottom surface of a housing attachable to the dispensing nozzle about the second end thereof, any of the quantity of the medium dispensed out of the second end of the dispensing nozzle, but not directed into the one or more chambered recess, into the one or more chambered recess, the bottom surface of the housing extending away from the dispensing nozzle and adjacent to the carrying mechanism, in step 604.
The apparatus, system, and method disclosed herein resolves issues that may be present in current technical solutions for filling chambered packages because the dispensing apparatus, in particular, provides a focused product stream that minimizes product waste, reduces wear on components of the system and reduces maintenance frequency and associated downtimes. The number of components in the design of the dispensing apparatus also simplifies designs compared with other current technical solutions thereby reducing maintenance and operation costs. Further, the apparatus, system, and method disclosed herein are entirely flexible due to the design and prototyping used. More particularly, rapid prototyping to quickly fabricate a scale model of the dispensing apparatus using computer aided design software in conjunction with a 3D printing or other additive layer manufacturing technology reduces lead time to days versus weeks, increases operational and design flexibility by lending itself to complex geometric designs not easily recreated using conventional machining techniques, increases speed and lowers cost to trial. Therefore, the apparatus, system, and method disclosed herein provide a solution to the problem of filling chambered packages.
Many modifications and other embodiments of the disclosure set forth herein will come to mind to one skilled in the art to which these disclosure pertain having the benefit of the teachings presented in the foregoing descriptions. Therefore, it is to be understood that the disclosure is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
