DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1 and 2 illustrate internal side and front views, respectively, of a blower assembly 10 according to an embodiment of the present invention. Referring to FIGS. 1 and 2, the blower assembly 10 includes a blower enclosure or cover 12 having a bottom wall 14 integrally formed with lateral walls 16, which are in turn integrally formed with a top wall 18. Alternatively, the cover 12 may be a hood that is removably secured to a base or bottom wall 14. For example, the cover 12 may be latchably secured to the base or bottom wall 14.
The blower enclosure 12 may also include front and rear access doors, such as shown and described in U.S. patent application Ser. No. 11/545,244, entitled “Blower Enclosure,” filed Oct. 10, 2006, which is hereby incorporated by reference in its entirety. The walls 14, 16, and 18, and the access door(s) define an internal chamber 20. A centrifugal blower 22 and a motor 24, such as an electric motor, are secured within the internal chamber 20. The blower 22 and the motor 24 may be secured to an interior surface of the bottom wall 14 through brackets 26 and fasteners 28. The blower 22 may be operatively connected to the motor 24 through belts, pulleys, and the like (not shown).
The blower 22 is, in turn, operatively connected to an outlet pipe 30 that is configured to deliver air from the blower 22 out of the blower assembly 10. The outlet pipe 30 may pass through a front wall (or any other wall) of the enclosure 12.
The enclosure 12 may be formed of polypropylene and may be secured to a base 32 including legs 34 connected by at least one cross beam 36. Adjustable feet 38 may be threadably secured to bottom surfaces of the legs 34. The adjustable feet 38 are configured to allow the four lower corners of the base 32 to be adjusted so that the blower assembly 10 may be leveled. The enclosure 12 protects the blower 22, the motor 24, and other internal components, such as air filters (not shown), from moisture and debris, as well as in wash-down environments and reduces sound levels to within OSHA standards.
FIGS. 3 and 4 illustrate top and end views, respectively, of an air manifold 40 according to an embodiment of the present invention. The manifold 40 may be a tubular plenum formed of plastic, metal or various other materials. Referring to FIGS. 3 and 4, the manifold includes a main cylindrical body 42 having a closed end 44 and an open end 46. The open end 46 may be threaded to receive a reciprocal threaded end of an air duct (not shown in FIGS. 3 and 4). An internal chamber 48 is defined within the main cylindrical body 42.
The manifold 40 may include a plurality of threaded openings 50 that are configured to threadably retain ends of air nozzles 52. Optionally, the air nozzles 52 and manifold 40 may be integrally formed as a single piece. Distal ends 54 of the air nozzles 52 are open so that air may be passed from the manifold 40 into the air nozzles 52 and out through the distal ends 54. As shown in FIGS. 3 and 4, the distal ends 54 may be tapered to increase the pressure of air passing out of the air nozzles 52.
The air nozzles 52 may be flared, round or various other shapes. FIG. 5 illustrates a side view of a round air nozzle 56 according to an embodiment of the present invention. The round air nozzle 56 includes an expanded distal end 58, thereby providing a wider stream of air. Round nozzles, such as the air nozzle 56, are particularly well-suited for drying the bottoms of aluminum cans.
FIG. 6 illustrates a side view of a flexible air duct 60 according to an embodiment of the present invention. The air duct 60 is formed of a flexible material, such as rubber, flexible plastic, or the like. The air duct 60 may be a hose having open ends 62 and 64 connected by a central channel. The end 62 is configured to secure over or into the open end 46 (shown in FIG. 3) of the air manifold 40. For example, the end 62 may be internally threaded and threadably engage the open end 46 of the air manifold 40. Optionally, the end 62 may be clamped over the open end 46 through a clamping ring 66.
The end 64 is configured to secure over or into the outlet pipe 30 (shown in FIGS. 1 and 2) of the blower assembly 10. Thus, air may be forced from the blower assembly 10 (shown in FIGS. 1 and 2) into the air duct 60 and into the manifold 40 (shown in FIGS. 3 and 4).
FIGS. 7 and 8 illustrate front and side views, respectively, of a bracket assembly 68. Referring to FIGS. 7 and 8, the bracket assembly 68 includes a base 70 that is configured to be secured to a conveyor line (not shown in FIGS. 7 and 8) through fasteners. The base 70 includes lateral walls 72 connected to a rear wall 74. The lateral walls 72 include aligned arcuate paths 76 formed through upper rear ends. Extension beams 78 are connected to the lateral walls 72 through adjusting clamps 80. The adjusting clamps 80 include fasteners 81 integrally connected to levers 82. The fasteners 81 pass through the arcuate paths 76 and are secured to lower ends 79 of the extension beams 78, thereby securing the extension beams 78 to the lateral walls 72. The levers 82 may be engaged to selectively tighten and loosen the engaging interface between the extension beams 78 and the lateral walls 72. When loosened, the extension beams 78 may be pivoted with respect to the laterals walls 72 in the directions of arc A. The levers 82 may then be engaged to secure the extension beams 78 in position at a desired location along arc A. The extension beams 78 may be connected together by one or more cross beams, rods or the like 84.
Upper ends 86 of the extension beams 78 are secured to aligned manifold brackets 88. The manifold brackets 88 may be separate and distinct from one another, or they may be connected through a beam or the like. The upper ends 86 of the extension beams 78 are pivotally secured to the manifold brackets 88 through adjusting clamps 90, similar to the adjusting clamps 80. The adjusting clamps 90 allow the manifold brackets 88 to pivot relative to the upper ends 86 of the extension beams 78 in the directions of arc B.
Manifold passages 92 are formed through distal ends 94 of the manifold brackets 88 and are configured to receive and retain the air manifold 40 (shown in FIGS. 3 and 4). Cam levers 96 are configured to secure the manifold 40 in place. That is, the cam levers 96 may be tightened to secure the manifold 40 into the manifold passages 92, and loosened to allow the manifold 40 to be removed from the manifold passages 92.
When the manifold 40 is secured within the manifold brackets 88, the position of the manifold 40 may be adjusted through a range of positions. That is, the adjusting clamps 78 may be engaged to move the extension beams 78 through a range of motion denoted by arc A, while the manifold bracket 88 may be moved through directions relative to the upper ends 86 of the extension beams 78 through the adjusting clamps 90.
FIGS. 9 and 10 illustrate isometric front and rear views, respectively, of a power drying system 100 according to an embodiment of the present invention. Referring to FIGS. 9 and 10, the power drying system 100 includes the blower assembly 10 (not shown in FIG. 10) positioned relative to a conveyor line 102. The conveyor line 102 moves containers 104, such as cans or bottles, past the blower assembly 10 and underneath the air manifold 40. The air manifold 40 is mounted on the conveyor line 102 upstream of a date coding assembly (not shown).
The outlet pipe 30 of the blower assembly is connected to the end 64 of the air duct 60, while the end 62 is secured to the open end 46 of the air manifold 40. The air duct 60 may be secured to the outlet pipe 30 and the air manifold 40 through clamping rings 66.
The air manifold 40 is securely positioned over the conveyor line 102 through the bracket assembly 68. The base 70 of the bracket assembly 68 may be securely fastened, such as through screws, to a lateral wall of the conveyor line 102. The plurality of air nozzles 52 expel air supplied from the blower assembly 10 down onto the containers 104 passing on the conveyor line 102, thereby blowing off moisture and/or contaminants. The air manifold 40 may be adjusted through a variety of positions by way of the adjusting clamps 80 and 90, as discussed above with respect to FIGS. 7 and 8. Thus, the air manifold 40 may be adjusted depending upon the size of the containers 104 passing underneath.
The containers 104 pass under each of the nozzles 52. Thus, if the first nozzle 52 that a container 104 encounters does not completely dry the area to be date coded on the container, the nozzles 52 downstream from the initial nozzle 52 ensure that the relevant area is dry.
As demonstrated above, embodiments of the present invention provide a more efficient system and method of removing water and impurities from containers before a date code printing/marking process. The blower assembly 10 provides relatively low pressure, high volume air that is ducted through the air duct 60 to the air manifold 40, which is then expelled through the air nozzles 52, thereby blowing water and impurities off the containers 104. Once water and impurities are removed from the containers 104, date codes may be accurately printed on the containers 104. The bracket assembly 68 allows the air manifold 40 to be adjusted vertically (e.g., the mounting brackets 88 pivoting with respect to the upper ends 86 of the extension members 78) and horizontally (e.g., the extension beams 78 pivoting with respect to the base 70) with respect to the conveyor line 102 so that the air nozzles 52 may be positioned in close proximity to the area where the containers 104 will be marked with date codes. Once the air manifold 40 is pivoted to an appropriate position, the air manifold 40 is locked in place through the adjusting clamps 80 and 90.
FIGS. 11, 12 and 13 illustrate, respectively, an isometric top view, a side view and a front view of a bracket assembly 110 securing an air manifold 112 according to an embodiment of the present invention. Referring to FIGS. 11-13, the bracket assembly 110 is generally the same as the bracket assembly 68 shown and described with respect to FIGS. 7-10. The air manifold 112 includes a plurality of air nozzles 114 that are configured to be oriented above a conveyor line, as discussed above. The air manifold 112 also includes air outlets 116 at either end. Flexible air conduits 118 are secured within the air outlets 116. Because the air conduits 118 are flexible, they may be fashioned to bow out, as shown in FIGS. 11-13, such that opposing air nozzles 120 will straddle containers passing underneath on a conveyor line.
While the conduits 118 may be flexible, they may alternatively be rigidly fixed in the positions shown in FIGS. 11-13. The air nozzles 120 may be similar to the air nozzles 56 shown and described with respect to FIG. 5 or may be similar to the air nozzles 52 shown and described with respect to FIG. 3.
In operation, the air nozzles 114 dry the top portions of containers passing underneath on a conveyor line, while the air nozzles 120 are directed towards the sides of the containers. While the conduits 118 and nozzles 120 are shown at ends of the air manifold 112, additional conduits may be positioned at various other positions of the manifold. For example, conduits 118 may be positioned at the middle of the air manifold 112 in addition to, or in lieu of, the conduits 118 at the ends of the air manifold 112.
Thus, embodiments of the present invention provide an efficient and cost-effective system and method of removing water and impurities from containers before date code printing. Embodiments of the present invention provide a system and method that may save an operator operating costs, when compared to conventional commercial compressed air driven nozzles.
Embodiments of the present invention provide a power drying system having a position selectable bracket assembly 68 that allows the air manifold 40 to be adjusted over the product conveyor line 102. As such, the air manifold 40 may be adjusted to accommodate containers 104 of various shapes and sizes.
