1. Field of the Invention
The present invention relates to systems and methods for dispensing automotive appearance care products. Embodiments relate to a transportable, compact system for dispensing multiple automotive appearance care products.
2. Description of the Related Art
Current methods for providing customers with automotive appearance care products involve either supplying the customer with pre-made solutions in large, heavy containers or providing the customer with containers of concentrated fluids and having the customer combine the concentrated fluids with a carrier fluid (e.g., water) to obtain the desired product.
Supplying the customer with pre-made solutions requires delivery and handling of large, heavy containers, which can be costly for the customer. The heavy containers also may be difficult to move from location to location, if so desired. If the customer is a distributor, the customer must also provide a means for transferring the product from the large container to a container suitable for consumers. This process can be time consuming and material may be wasted in the transfer process. It may also be difficult for the distributor to track the amount of product given to consumers if consumers desire varying amounts of product. Storage of the large containers may also take up valuable warehouse or storage space.
Providing the customer with concentrated fluids may reduce the size of containers delivered to the customer, thus saving space and reducing delivery costs. Combining the concentrated fluids with a carrier fluid however, may result in a significant waste of time and money. In addition, improper mixing of the fluids by the customer may result in unreliable product uniformity. Again, it may be difficult for a distributor to easily track the amount of product given to a consumer if consumers desire varying amounts of product. For the customer to be provided with a variety of products, multiple concentrated fluids must be mixed with carrier fluids, which can be a difficult process and can significantly increase the difficulty in tracking product costs to be charged to a consumer.
Thus, there is a need to dispense multiple automotive appearance care products from a system that can be used to accurately track and dispense a large amount of product, saves space, and transports easily. It may also be advantageous to automatically control product dispensing.
In an embodiment, a system for dispensing a plurality of product fluids may include a plurality of containers. Each container may contain a base fluid. A carrier fluid supply may be coupled to a first conduit to provide a source of carrier fluid. The carrier fluid may be pressurized in the system to provide a substantially constant pressure of carrier fluid. Pressurizing the carrier fluid in the system may provide a more transportable apparatus that can be moved from one location to another location without a need to modify the system. A valve coupled to the first conduit and a supply conduit may control a flow of the carrier fluid from the first conduit to the supply conduit. The base fluid may be mixed with the flow of carrier fluid in the supply conduit.
An injector may control mixing of the base fluid with the carrier fluid to form a product fluid in the supply conduit. In some embodiments, more than one injector for mixing the carrier fluid with more than one base fluid may be disposed along the supply conduit.
A metering device may be coupled to the supply conduit to determine an amount of product fluid dispensed during use. Monitoring the amount of product fluid dispensed by using a metering device may improve the ability to track and determine costs for charging users of the apparatus. A plurality of supply conduits may be disposed in the system and coupled to the first conduit. In certain embodiments, each supply conduit may produce a different product fluid. A separate metering device may be used for each product fluid dispensed.
Each product fluid may be dispensed through an exit valve. In some embodiments, more than one exit valve may be used. Multiple automotive appearance care product fluids may be dispensed in a diluted composition for immediate use. The system may be used to dispense multiple product fluids from a single apparatus regardless of the chemical compatibility of the fluids. The multiple automotive appearance care product fluids may also be dispensed in a concentrated composition requiring dilution before use.
In certain embodiments, a system for dispensing a plurality of automotive appearance care products includes a plurality of storage containers. A raw material may be placed in each storage container. One or more mixing containers may be coupled to each storage container.
Raw materials from the storage containers may be combined with a carrier fluid. The combined raw materials and carrier fluid may be provided to a plurality of mixing containers. In addition, a powder may be added, either manually or automatically, to each mixing container. The raw materials, powders, and/or carrier fluid may be combined in the mixing containers to produce a plurality of mixtures.
Mixtures from the mixing containers may be provided to a plurality of mixing systems. The mixing systems may be located in a dispensing apparatus. The mixing systems may combine the mixtures with carrier fluid to produce a plurality of product fluids. The product fluids may be dispensed to a plurality of storage vessels. A plurality of pumps may be coupled to the storage vessels to pump the product fluids from the storage vessels to a plurality of dispensing conduits. The dispensing conduits may be used to dispense automotive appearance care products that are ready for immediate use by a user.
Systems for dispensing a plurality of automotive appearance care products as described herein may be used in high volume areas (i.e., areas with a high throughput of automobiles processed using the automotive appearance care products). For example, a system may be used to treat between about 150 and about 250 automobiles per day. Using more than one system may substantially increase a possible throughput of automobiles.
In an embodiment, a dispensing apparatus may include storage containers, mixing systems, storage vessels, pumps, and/or dispensing conduits. The storage containers, mixing systems, storage vessels, pumps, and/or dispensing conduits may be located in a housing. The storage containers may contain one or more raw materials. The raw materials may be mixed with a carrier fluid by mixing systems to produce one or more automotive appearance care product fluids. The product fluids may be stored in storage vessels before being dispensed. Pumps may produce a flow of product fluids to one or more dispensing conduits. The dispensing conduits may be used to dispense the product fluids for use as automotive appearance care products.
In an embodiment, a cost to be charged to a user may be based on a number of automobiles the user treats using the automotive appearance care products produced by a system for dispensing product fluids. In certain embodiments, a cost to be charged to a user may be based on a per application basis. Charges based on a number of treated automobiles or on a per application basis, rather than on an amount of fluid dispensed or fluid used, may reduce the number of costs associated with using the automotive appearance care products that a user of the system may have to consider for budgeting.
In some embodiments, product fluids (or automotive appearance care products) may be dispensed substantially automatically by the system. Automatically dispensing products may reduce excess use of raw materials or base fluids by a user of the system. Automation may include limiting operating of the system by use of an on/off switch and/or dispensing the product fluids by operating a fluid applicator. Such automation may increase a lifetime of the system or apparatus and/or control the use of fluids and materials in the system.

An embodiment of a compact, transportable automotive appearance care product dispensing apparatus is shown in
In
In an embodiment, tube 11 may be made of vinyl tubing (e.g., Tygon® tubing). Container 10 may be made of an inert polymeric material. Containers 10 may be placed on shelves 12. Shelves 12 may be perforated to allow for spilled or leaked fluid to be collected and removed at bottom of main cabinet 5. A perforated shelf may also be used to separate top cabinet 2 from main cabinet 5, allowing fluid spilled or leaked from the top cabinet to be collected and removed at the bottom of the main cabinet. In one embodiment, up to approximately 5 gallons of base fluid may be disposed in container 10. Container 10 may comprise a variety of shapes.
The base fluid may be any fluid used as a component for an automotive appearance care product. The base fluid may be a cleaning agent or a surfactant. Examples of a surfactant may be a nonionic surfactant, a cationic surfactant, a siloxane polymer surfactant, or an organosiloxane polymer surfactant. A nonionic surfactant may include nonylphenol ethoxylates, octylphenol ethoxylates, and/or ethoxylated alcohols. A cationic surfactant may be, for example, a quaternary ammonium compound. An example of a siloxane polymer surfactant may be dimethylpolysiloxane. A surfactant may also be an anionic surfactant such as a linear alkyl sulfonate.
The base fluid may be a wetting agent. Wetting agents may include fatty acid salts, long chain (between about 12 and about 20 carbon atoms) alcohols, or sodium alkyl sulfates. An example of a sodium alkyl sulfate is sodium lauryl sulfate.
The base fluid may be an emulsifier. An emulsifier may be a surface-active agent that reduces interfacial tension between a continuous phase and a dispersed phase in an emulsion. An example of an emulsifier may be coconut fatty acid amide or another alkanolamide.
The base fluid may be a glycol ether. Examples of glycol ethers include 2-butoxyethanol, propylene glycol monobutyl ether, and dipropylene glycol monobutyl ether.
The base fluid may be an acid. Examples of acidic base fluids include phosphoric, sulfuric, or sulfonic acids. The base fluid may be a glass cleaner. A glass cleaner may be a combination of alcohol, surfactant, and water. The base fluid may also include petroleum distillates, acrylic fluoropolymer resins, aliphatic hydrocarbons, or alcohols. The base fluid may be a foaming agent. In some embodiments, the base fluid may include fragrance and/or dye.
A system for mixing at least one base fluid with a carrier fluid to form an automotive appearance care product fluid may be disposed in top cabinet 2. A schematic for an embodiment of system 15 for injecting at least one base fluid into the carrier fluid to form a plurality of automotive appearance care product fluids is shown in
First conduit 18 may include copper tubing with a diameter of about ½ inch. A plurality of supply conduits 20a–20e may be coupled to first conduit 18 using suitable connectors 19. In the embodiment of
Supply conduit 20 may include valve 21 coupled to first conduit 18. Valve 21 may allow a flow of the carrier fluid from first conduit 18 to supply conduit 20. Valve 21 may be, for example, a normally-closed valve. Valve 21 may be operated by switch 3 located outside of top cabinet 2, as depicted in
Supply conduit 20 may include injector 22. Injector 22 may inject the base fluid into the carrier fluid. Injector 22 may be coupled to container 10 with tube 11 (shown in
In an embodiment, each container 10 may be coupled to multiple injectors 22 disposed in separate supply conduits 20a–20e. Each injector may inject a different amount of base fluid into the carrier fluid in each supply conduit. The amount of base fluid injected may be predetermined by a setting of the injector. This may be accomplished with the use of a “T” connector on tube 11 commonly used in the art of plumbing fluid lines. The “T” connector, or more than one “T” connector, may be located in main cabinet 5 (shown in
Product fluid may flow through metering device 25 coupled to each supply conduit 20a–20e. Metering device 25 may determine an amount of product fluid dispensed from supply conduit 20 during use of apparatus 1. An example of metering device 25 is a Fill-Rite made by Tuthill Corporation (Burr Ridge, Ill.). The amount of product fluid dispensed may be determined as a total volume in gallons dispensed of product fluid. Metering device 25 may determine a total amount of product fluid dispensed from apparatus 1 during its lifetime, an “odometer” function. Metering device 25 may determine an amount of product fluid dispensed during a single use, or a specific number of uses, a “trip meter” function. In an embodiment, metering device 25 determines both “odometer” and “trip meter” amounts simultaneously and may show either amount on a display or on a computer coupled to the metering device. Monitoring the amount of product fluid dispensed may be used to determine a cost associated with the amount dispensed in order to charge the cost to an end user or other customer.
Supply conduits 20a–20e may be coupled to at least one exit valve 7 through exit conduits 26a–26e. Exit valve 7 may be used to dispense product to an external container or other such vessel. Coupling to exit valve 7 may be done by methods well known in the art. In some embodiments, a single exit valve 7 is used for product fluids that are chemically compatible. In an embodiment for chemically non-compatible product fluids, one or more additional exit valves may be used. In the embodiment of
In an embodiment shown in
In an embodiment, the system may be used to dispense automotive appearance care products that are used in a high volume area. For example, a system for dispensing a plurality of product fluids may be used for processing approximately 150 to approximately 250 automobiles per day. Such a high volume location may be, for example, at an automobile auction. Products similar to those used in automotive appearance care may possibly be dispensed from a system used according to embodiments described herein.
Storage container 102 may contain a raw material. The raw material may include materials used as a base material for producing an automotive appearance care product. For example, the raw material may include a liquid concentrate of an automotive appearance care product. In an embodiment, storage container 102 is a 55 gallon drum containing a liquid concentrate. Storage container 102 may have opening 110. Conduit 112 may be placed in opening 110 and coupled to mixing container 104. In an embodiment, conduit 112 allows raw material to flow from storage container 102 to mixing container 104. In some embodiments, storage container 102 may be coupled to more than one mixing container 104 with one or more conduits (i.e., one storage container 102 may supply raw material to more than one mixing container 104). Conduit 112 may extend proximate bottom of storage container 102. Conduit 112 may include materials chemically inert to the liquid concentrate such as, but not limited to, PVC or polyethylene.
Conduit 112 may be coupled to mixing system 114. Mixing system 114 may be coupled to mixing container 104. Mixing system 114 may be placed at or in an opening in cover 132 of mixing container 104. Mixing system 114 may include body 115, valve 118, mixing valve 116, and float 124, as shown in
When valve 118 is opened, carrier fluid may enter body 115 of mixing system 114 (shown in
As shown in
In certain embodiments, dilution tip 117 may be selected and/or installed by a distributor of the apparatus. The distributor of the apparatus may select the desired product fluids to be dispensed by the dispensing apparatus (and/or their corresponding raw materials), and select and/or install corresponding dilution tips for each valve 116. In some embodiments, a manufacturer or user of the dispensing apparatus may select and/or install the dilution tips for each valve 116.
The combined raw material and carrier fluid may flow through mixing valve 116 and to mixing container 104, as shown in
In some embodiments, valve 119 may be coupled between valve 118 of mixing system 114 and carrier fluid supply conduit 122. Valve 119 may be a solenoid valve. Valve 119 may be either electrically or pneumatically operated. In an embodiment, valve 119 is a normally-closed solenoid valve. Valve 119 may be used to control the flow of carrier fluid between carrier fluid supply conduit 122 and mixing system 114. Closing valve 119 may inhibit the flow of carrier fluid to mixing system 114. Valve 119 may be operated by a switch. The switch may be controlled by a user or, in some embodiments, may be automatically controlled (e.g., by a computer or a timing device).
In some embodiments, a powder may be added to mixing container 104. Mixing container 104 may include cover 132 with lid 133. Lid 133 may be opened to allow for adding of a powder to mixing container 104. The powder may include a base material for producing an automotive appearance care product. An example of powder may include, but not be limited to, caustic soda. In some embodiments, powder may be added to mixing container 104 while valve 118 is open. In an embodiment, powder may be automatically added to mixing container 104 at a specified time. Powder may be added using an automated dispensing system. The automated dispensing system may be coupled (e.g., interlocked) with mixing system 114 to provide powder to mixing container 104 substantially simultaneously with carrier fluid and raw material dispensed by mixing system 114. Mixing container 104 may include materials substantially inert to carrier fluid, raw material, powder, and any combination thereof. For example, mixing container 104 may be a cylindrical polyethylene container obtainable from Chem-Tainer Industries (West Babylon, N.Y.).
Mixer 128 may be placed in mixing container 104. Mixer 128 may be a stirrer. For example, mixer 128 may be a four-bladed stirrer as shown in
In an embodiment, mixer 128 may be turned on and valve 119 opened substantially simultaneously. A switch may be used to provide power to mixer 128 and open valve 119 at substantially the same time. In certain embodiments, valve 119 is a solenoid valve that opens when power is applied to the valve (e.g., a normally-closed solenoid valve). In some embodiments, the switch may be coupled (e.g., interlocked) to float 124 such that power is not provided to valve 118 or mixer 128 until the float is above a specified height in mixing container 104. Mixer 128 and valve 119 may also be placed on a timing device (e.g., a clock timer) such that they operate for a specified time. In some embodiments, the timing device may be included in a switch. For example, the timing device may be set so that power is provided to mixer 128 and valve 119 for approximately 30 minutes or, in some embodiments, a time between about 20 minutes and about 40 minutes. The specified time may be determined by a time needed for substantially complete mixing of the contents of mixing container 104.
In some embodiments, float 124 may reach a specified height in mixing container 104, thus closing valve 118 in mixing system 114 before the timing device turns off power to mixer 128 and valve 119. For example, the specified height in the mixing container may be reached after a time less than the specified time of the timing device (e.g., about 10 minutes) while mixer 128 will run and valve 119 will be open for the specified time (e.g., about 30 minutes). In other embodiments, mixer 128 and valve 119 may be separately controlled by one or more timing devices. Using the mixer for a period of time after filling the mixing container may produce a more uniform mixture in the mixing container and, thus, a better product quality. In an embodiment, after the timing device turns off power to mixer 128 and valve 119, the flow of carrier fluid through valve 119 and to mixing system 114 may be reduced or stopped to inhibit unnecessary filling of mixing container 104. For example, inhibiting flow of carrier fluid through valve 119 may inhibit automatic filling of mixing container 104 with carrier fluid and raw material without adding powder to the mixing container (i.e., mixing container 104 cannot be filled with raw material and carrier fluid if float 124 opens valve 118 in mixing system 114 because there is no flow of carrier fluid through valve 119). Controlling the flow of carrier fluid may also allow for control of the production of a mixture in a mixing container so that the mixture cannot be produced until a mixing container is substantially empty.
In some embodiments, contents of mixing container 104 may substantially mix without using mixer 128 (e.g., if the mixture contains only raw material and carrier fluid). The raw material and carrier fluid may be substantially mixed by mixing system 114. In such a case, a timing device or switch may be used to open and close valve 119 to control the flow of carrier fluid as described herein.
As shown in
One or more mixing systems 140 may be placed in an upper portion of dispensing apparatus 106 as shown in
One or more pumps 150 may be placed in an upper portion of dispensing apparatus 106 above mixing systems 140. However, a location of pumps 150 may vary in dispensing apparatus 106. Each pump 150 may be coupled to a storage vessel 160 with conduit 162. In an embodiment, one pump 150 is coupled to each storage vessel 160, which is coupled to each mixing system 140. Thus, a number of pumps may typically be equal to a number of storage vessels and a number of mixing systems.
As shown in
When valve 146a is opened, carrier fluid may enter body 115 of mixing system 140a through valve 146a. The carrier fluid may flow through mixing valve 142a. Mixing valve 142a may be, for example, a venturi valve. In some embodiments, mixing valve 142a may include an injector or dilution tip. Mixing valve 142a may be used to combine carrier fluid with material from mixing container 104a, as shown in
As shown in
The combined material and carrier fluid may flow through mixing valve 142a and to storage vessel 160a through conduit 144a, as shown in
Mixing system 140a may include float 148a. Float 148a may rise and fall with a level of fluid in storage vessel 160a. Float 148a may turn on and/or off mixing system 140a. The status (on or off) of mixing system 140a may be controlled by operation (i.e., opening or closing) of valve 146a. A position of float 148a may cause valve 146a to open or close. In an embodiment, valve 146a is opened when float 148a falls below a lower specified height. Valve 146a may be closed when float 148a rises above an upper specified height. This process may automatically open and close valve 146a based on a level of float 148a in storage vessel 160a. Thus, an automatic re-filling process for storage vessel 160a may be provided.
Conduit 162a may substantially extend into storage vessel 160a proximate a bottom of the storage vessel. Conduit 162a may couple storage vessel 160a to pump 150a. Any of the conduits described herein (e.g., conduit 162a, conduit 130, conduit 144a) may include, but not be limited to, substantially chemically inert materials such as polyethylene, PVC, etc.
Pump 150a may be used to pump product fluid from storage vessel 160a to dispensing conduit 108a. Pump 150a may be any pump that provides a pressure of product fluid to dispensing conduit 108a. In an embodiment, pump 150a is a diaphragm pump or a double diaphragm pump. For example, pump 150a may be an air-operated ARO ¼″ non-metallic diaphragm pump available from Ingersoll Rand Co. (Woodcliff Lake, N.J.). Pump 150a may also be obtained from Flojet Corporation (Foothill Ranch, Calif.) (e.g., model number 5100-020 or model number G573205-Viton). Air may be supplied to pump 150a through an air supply conduit located in dispensing apparatus 106. The air supply conduit may include a central conduit with branches coupled to each pump 150a–150i in dispensing apparatus 106. A regulator may be coupled to the air supply conduit to control the pressure of air supplied to pump 150a (and other pumps 150). In an embodiment, the regulator may provide a pressure of about 40 psi to pump 150a. Other pressures may be used depending on, for example, a desired application of product fluids or a desired flow rate of product fluids. Pump 150a may be turned on by a user of dispensing apparatus 106. In some embodiments, pump 150a may be turned on by a switch located on dispensing apparatus 106. In certain embodiments, pump 150a (and pumps 150(b–i)) may run continuously with power supplied to dispensing apparatus 106.
Dispensing conduit 108a may be coupled to an outlet port of pump 150a. Fluid applicator 109 may be coupled to an end of dispensing conduit 108 (as shown in
In some embodiments, one or more additional dispensing conduits may be coupled to dispensing conduit 108a. In certain embodiments, a metering device (e.g., a metering device as described in the embodiment of
As shown in
Storage containers 102 may contain one or more raw materials. The raw materials may include materials used as a base material for producing an automotive appearance care product. For example, the raw material may include a concentrated form of an automotive appearance care product (e.g., a liquid concentrate). In an embodiment, each storage container 102 is a 5 gallon container containing one raw material or liquid concentrate. Larger storage containers may be used as desired depending on an application of system 100. Conduits 130 may be placed in storage containers 102 (shown schematically in
Conduits 130 may be coupled to mixing systems 140. Each conduit 130 may be coupled to one mixing system 140. In some embodiments, more than one conduit 130 may be coupled to one mixing system 140 such that the mixing system combines two or more raw materials with a carrier fluid. Conduits 130 may couple to mixing systems 140 at valves 142 (as shown in
Carrier fluid supply 132 may be coupled to supply systems 136(a–d). Carrier fluid supply 30 may be provided by a user of dispensing apparatus 106. Carrier fluid supply 30 may be removably coupled to carrier fluid supply conduit 134 using a quick-coupling connection. Using a quick-coupling connection to couple dispensing apparatus 106 to a carrier fluid supply and/or an air supply allows the dispensing apparatus to be mobile and transportable (e.g., transportable within a local area such as an automobile auction, transportable from user to user, or transportable from one location to another by a user).
Supply system 136a may include storage container 102a, mixing system 140a, storage vessel 160a, pump 150a, dispensing conduit 108a, and/or dispensing conduit 108a′. Supply systems 136b–136d may include similar components represented by corresponding reference numbers. Storage container 102a may be coupled to mixing system 140a with conduit 130a. Carrier fluid supply conduit 134 may provide carrier fluid (e.g., water) to mixing system 140a. In some embodiments, a regulator may be used to control a pressure of carrier fluid in carrier fluid supply conduit 134. Mixing system 140a may be coupled to storage vessel 160a with conduit 144a. Conduit 162a may couple storage vessel 160a to pump 150a. Dispensing conduit 108a and dispensing conduit 108a′ may be coupled to pump 150a. Dispensing conduit 108a and dispensing conduit 108a′ may dispense identical product fluid from storage vessel 160a. In certain embodiments, dispensing conduit 108a and dispensing conduit 108a′ may be useable on different sides of dispensing apparatus 106, as shown in
As shown in
When valve 146a is opened, carrier fluid may enter body 115 of mixing system 140a through valve 146a. The carrier fluid may flow through mixing valve 142a. Mixing valve 142a may be, for example, a venturi valve. In some embodiments, mixing valve 142a may include an injector or dilution tip. Mixing valve 142a may be used to combine carrier fluid with raw material from storage container 102a, as shown in FIG. 11. In an embodiment, when carrier fluid flows through mixing system 140a, mixing valve 142a siphons fluid from conduit 130a. This siphoning may produce a flow of raw material through conduit 130a. The raw material may be combined with carrier fluid in mixing valve 142a. A proportion of raw material to carrier fluid produced by mixing valve 142a may be determined by a design of the mixing valve.
As shown in
In certain embodiments, dilution tip 117 may be selected and/or installed by a distributor of the apparatus. The distributor of the apparatus may select the desired product fluids and/or corresponding raw materials to be dispensed by the dispensing apparatus and select and/or install corresponding dilution tips for each valve 142a. In some embodiments, a manufacturer or user of the dispensing apparatus may select and/or install the dilution tips for each valve 142a.
The combined raw material and carrier fluid may flow through mixing valve 142a and to storage vessel 160a through conduit 144a, as shown in
Mixing system 140a may include float 148a. Float 148a may rise and fall with a level of fluid in storage vessel 160a. Float 148a may turn on and/or off mixing system 140a. The status (on or off) of mixing system 140a may be controlled by operation (i.e., opening or closing) of valve 146a. A position of float 148a may cause valve 146a to open or close. In an embodiment, valve 146a is opened when float 148a falls below a lower specified height. Valve 146a may be closed when float 148a rises above an upper specified height. This process may automatically open and close valve 146a based on a level of float 148a in storage vessel 160a. Thus, an automatic re-filling process for storage vessel 160a may be provided.
As shown in
In certain embodiments, different product fluids may have different colors (e.g., different dyes may be added to the raw materials to produce different product fluid colors). The varying colors may be used to distinguish between product fluids in each storage vessel 160. The product fluids may also be colored to provide a visually stimulating display (i.e., aesthetically pleasing view) to a user of dispensing apparatus 106 or a customer. Storage vessels 160 with visibly transparent walls may allow a user to view the various colors of the product fluids and/or to view the level of the product fluid in each storage vessel. If there is a problem with a particular storage vessel (e.g., the storage vessel is not filling properly), the user may easily view and/or inspect the problem through a transparent wall. The user may then contact a distributor or manufacturer of dispensing apparatus 106 for help in correcting the problem.
Product fluids may be stored in storage vessels 160 until a user of the dispensing apparatus desires to dispense one or more product fluids. Storage vessels 160 may be automatically refilled by mixing systems 140 as described herein. In an embodiment, storage vessels 160 may have end caps that are removable from the bottom of the storage vessels. In some embodiments, the end caps may be removable only by a distributor or manufacturer of dispensing apparatus 106. The end caps may be removed to allow access to the inside of storage vessels 160 so that the storage vessels may be repaired, cleaned, etc.
As shown in
Dispensing conduits 108 may be coupled to pumps 150. In one embodiment, two dispensing conduits 108 are coupled to each pump 150. Coupling two dispensing conduits 108 to each pump 150 may allow each product fluid to be dispensed through each of the two conduits substantially simultaneously. Thus, dispensing apparatus may be used to provide product fluids simultaneously to more than one automobile (e.g., two automobiles at the same time). In certain embodiments, dispensing conduits 108 that dispense identical product fluids may be located so that the dispensing conduits 108 may be used on opposite sides of dispensing apparatus 106, or located so that more than one user can use the dispensing apparatus at one time. In an embodiment, four dispensing conduits used on one side of dispensing apparatus 106 (on a first automobile) may dispense four identical product fluids as four dispensing conduits used on another side of the dispensing apparatus (on a second automobile). Thus, dispensing apparatus 106 may be used to service two or more lanes of automobiles depending on a configuration of the dispensing apparatus.
As shown in
In an embodiment, portions of dispensing apparatus 106 may be placed in a housing. In one embodiment, the housing may be a cabinet. In certain embodiments, pumps 150, mixing systems 140, storage vessels 160, and storage containers 102 may be located in a housing. In some embodiments, any number and combination of pumps 150, mixing systems 140, storage vessels 160, and/or storage containers 102 may be located outside of a housing. The location of any of pumps 150, mixing systems 140, storage vessels 160, and storage containers 102 may depend on their size and/or use in dispensing apparatus 106. For example, for a large scale operation, storage containers 102 may be located outside of a housing (e.g., in a storage room) to accommodate storage containers that are large in size (e.g., 55 gallon drums).
In the embodiment depicted in
In one embodiment, the pumps and mixing systems may be enclosed in a section of housing 190 such that the pumps and mixing systems are accessible only to desired personnel (e.g., a distributor or manufacturer of dispensing apparatus 106). A section of the housing may be locked (e.g., by a cabinet key or locking panel) to limit access to the section. Access to the section containing the mixing systems may be limited to inhibit adjustment or replacement of, for example, dilution tips by unwanted personnel (e.g., a user). A user of dispensing apparatus 106 may only be allowed to access dispensing conduits 108 and fluid applicators 109. In certain embodiments, a user may be inhibited from accessing sections of the housing containing pumps, mixing systems, storage containers 102, and/or storage vessels 160. Limiting the access of a user to dispensing apparatus 106 may inhibit the user from, for example, misusing product fluids, wasting raw materials, damaging the dispensing apparatus, affecting mixing of raw materials and carrier fluid, etc. In some embodiments, a user may be allowed to replace storage containers 102. In other embodiments, only a distributor or manufacturer may be allowed to replace and/or refill storage containers 102. Only allowing the distributor or manufacturer to replace and/or refill storage containers 102 may inhibit placing the wrong raw materials in the dispensing apparatus and/or mis-aligning the raw materials in relation to their corresponding mixing system and storage vessel. Limiting access to dispensing apparatus 106 may also reduce the possibility of theft of materials.
In certain embodiments, a housing for dispensing apparatus 106 may have a profile that is relatively small. The housing may have a profile in at least one direction (e.g., a horizontal width) that is less than about 18 inches. Having a relatively small profile may reduce the space taken up by dispensing apparatus 106. Housing 190 may, in some embodiments, be coupled to a wall or other support structure. Coupling the housing to a wall may also reduce the space taken up by the housing. In some embodiments, a dispensing apparatus housing may be coupled to a wall and include an overhead coupling system (as shown in
In an embodiment, dispensing apparatus 106 may have a unique identifier or unique identification number. The unique identifier may be permanently located on housing 190 or dispensing apparatus 106. The unique identifier may be used to identify the apparatus to a manufacturer or distributor of the apparatus. For example, the unique identifier may be used to track the apparatus for leasing or selling purposes.
First ends of dispensing conduits 108 may be coupled to pumps 150, as shown in
In some embodiments, dispensing conduits 108 and/or fluid applicators 109 may be labeled to display information about the product fluid that is dispensed through each dispensing conduit or fluid applicator. The information displayed may include, for example, what the product fluid is, safety information about the particular product fluid, dispensing directions, etc. A manufacturer or distributor of dispensing apparatus 106 may label the dispensing conduits and/or fluid applicators. For example, a distributor may label the dispensing conduits and/or fluid applicators after selecting a dispensing conduit that corresponds to a storage vessel and a dilution tip used to fill that storage vessel using a mixing system. Labeling the dispensing conduits and/or fluid applicators may, for example, inhibit use of the wrong product fluids by a user of the dispensing apparatus and/or reduce the likelihood of misuse of the product fluid.
Using dispensing apparatus 106 to produce product fluids for use as automotive appearance care products may reduce chemical costs because of reduced waste of material during filling of containers or mixing of fluids. Dispensing apparatus 106 may reduce labor costs by reducing or eliminating time involved with filling containers, mixing fluids, and cleanup or transport of materials. Dispensing apparatus 106 may also reduce problems associated with container storage, handling, and disposal.
In certain embodiments, storage containers 102 may be 5 gallon containers filled with raw materials. The raw materials may be liquid concentrates of product fluids as described herein. In an embodiment, dispensing apparatus 106 may be able to produce about 20 gallons of a product fluid before a 5 gallon storage container containing the raw material corresponding to the product fluid needs to be refilled or replaced with a new, full storage container (i.e., the storage container is substantially empty). In some embodiments, dispensing apparatus 106 may be able to produce about 30 gallons, about 40 gallons, about 50 gallons, about 60 gallons, about 70 gallons, or more of a product fluid before a 5 gallon storage container containing the raw material corresponding to the product fluid needs to be refilled or replaced with a new, full storage container. The amount of each product fluid producible from a storage container before refilling or replacing the storage container depends on factors including, but not limited to, volume of the storage container, concentration of the raw material, dilution ratio of the raw material in a carrier fluid, and amount of product fluid used per automobile.
Dispensing apparatus 106 may be able to produce a sufficient amount of product fluids so that a relatively large number of automobiles or vehicles may be treated before a storage container has to be refilled or replaced. The number of automobiles treatable may depend on, for example, the product fluid with the smallest amount of product fluid produced by dispensing apparatus 106. For a ratio of about 1 gallon of product fluid used to treat 8 automobiles, about 20 gallons of product fluid will treat about 160 automobiles before the storage container needs to be replaced or refilled. In some embodiments, greater than about 100 automobiles, greater than about 200 automobiles, greater than about 300 automobiles, or more may be treatable using dispensing apparatus 106 before a storage container has to be refilled or replaced. The number of automobiles treatable using dispensing apparatus 106 before refilling or replacing a storage container depends on factors including, but not limited to, volume of the storage container, the concentration of the raw material, the dilution ratio of the raw material in a carrier fluid, and the amount of product fluid used per automobile.
Overhead coupling system 200 may be coupled to a ceiling or any other appropriate supporting structure. Overhead coupling system 200 may be used to provide a space between housing 190 and fluid applicator 109, as shown in
In certain embodiments, dispensing apparatus 106 may be leased or sold to a distributor. The distributor may allow a user to use dispensing apparatus 106 through a user contract (e.g., a lease contract or other type of agreement). The distributor may provide the user dispensing apparatus 106 and raw materials for use in the dispensing apparatus. For example, the distributor may provide storage containers 102 with raw materials. In some embodiments, the distributor may provide a user with one or more dispensing apparatus 106 preloaded with full storage containers 102. The number of dispensing apparatus 106 provided to the user may be determined by the user's desired application (e.g., the estimated number of vehicles to be treated by the user). The user may be allowed to use dispensing apparatus 106 until his application is done or until the dispensing apparatus runs out of raw material. The dispensing apparatus may then be refilled, replaced with a new dispensing apparatus, or taken back by the distributor.
In an embodiment, a distributor may provide dispensing apparatus 106 to a user. The distributor may allow the user to operate the dispensing apparatus (i.e., operate the dispensing conduits and fluid applicators). In certain embodiments, the user may only be allowed to operate the fluid applicators on the dispensing apparatus. The distributor may transport dispensing apparatus 106 to a site for the user. The distributor may set the floats and select and install dilution tips for each dispensing apparatus based on the user's application. The distributor may also load and couple the storage containers to the dispensing apparatus. The user may need to provide an air supply and/or a carrier fluid (water) supply to operate the dispensing apparatus. The distributor may couple the dispensing apparatus to the air and carrier fluid supplies. In some embodiments, the user may couple the dispensing apparatus to the air and carrier fluid supplies. After coupling the air and carrier fluid supplies to the dispensing apparatus and setting the floats, selecting and installing the dilution tips, air and carrier fluid may be supplied to the dispensing apparatus to begin filling the storage vessels and prepare the dispensing apparatus for use. After use, the dispensing apparatus may be decoupled from the air and carrier fluid supplies and transported back to the distributor or to another location.
In some embodiments, a user may lease or buy a dispensing apparatus. For example, the user may desire to use the dispensing apparatus through many cycles of refilling or replacing the supply of raw materials, or over an extended period of time (e.g., over several years). The user may have a contract or agreement to operate the dispensing apparatus for a certain time period or until either the user, a distributor, or a manufacturer desires to terminate use of the dispensing apparatus. Typically, a manufacturer or distributor may be responsible for resupplying raw materials for the dispensing apparatus and/or maintaining (e.g., repairing, maintaining, etc.) the dispensing apparatus. In some embodiments, the user may be allowed to replace or refill the storage containers in the dispensing apparatus. Responsibilities associated with use and/or maintaining of the dispensing apparatus may be outlined in a contract or agreement between a user, a distributor, and/or a manufacturer.
In certain embodiments, a cost charged to a user by a distributor or manufacturer may be assessed, or determined, based on the number of automobiles, or vehicles, that are treated, or will be treated, with fluids provided by an automotive appearance care product dispensing system. The user may be charged on a cost per vehicle treated basis for use of the automotive appearance care product dispensing system. The cost per vehicle treated may be based on a set rate. The set rate may be based on the average amount of fluids needed, which may be estimated or predetermined, for each vehicle treated with automotive appearance care product fluids. The set rate may include other costs such as chemical or material costs, freight costs, labor costs, etc. In some embodiments, the set rate may be adjusted for each vehicle based on certain variables such as, but not limited to, a size of a vehicle (e.g., compact, mid-size, full-size, etc.), the vehicle manufacturer, and/or the vehicle model. The average amount of product fluids to be used for treating a vehicle may change based on these variables (e.g., a full-size vehicle may require more fluids than a compact vehicle). Thus, the set rate for treating a certain type of vehicle may be adjusted accordingly.
In an embodiment, the cost charged to a user may be assessed, or determined, as the set rate multiplied by the number of vehicles treated by the user with one or more automotive appearance care products. The set rate may be assessed (e.g., predetermined) for the user before the user utilizes the automotive appearance care product dispensing system. The set rate may be assessed or determined by a manufacturer of the dispensing system, and/or a supplier of the automotive appearance care products and/or base materials for the automotive appearance care products. In certain embodiments, the manufacturer of the dispensing system may also be the supplier of the automotive appearance care products or base materials for the automotive appearance care products.
In some embodiments, a set rate may be assessed or determined for each individual automotive appearance care product. Individual set rates for each automotive appearance care product may be used in combination to determine a cost to be charged to a user of the dispensing system. Individual set rates may be used, for example, when certain automotive appearance care products are not used for certain types of vehicles. As another example, some automotive appearance care products may be used at one location for using the dispensing system but not at a second location for using the dispensing system. Thus, the set rate may be adjusted between locations based on which automotive appearance care products will be used at each location.
Charging a cost to the user based on a set rate, or, in some embodiments, on more than one set rate, may reduce the number of costs a user of an automotive appearance care product dispensing system has to track and/or monitor during use. The user may only have to budget for the number and/or type of automobiles processed since costs such as chemical or material costs, freight costs, labor costs, etc., are already factored into the set rate for each vehicle processed. The user may not need to budget separately for these other types of costs, thereby simplifying bookkeeping, inventory, and/or other tasks associated with monitoring, tracking, or budgeting. This simplification may allow a user to operate a business (e.g., a car dealership, a detail shop, or a vehicle auction) or process more efficiently.
In certain embodiments, a cost charged to a user by a distributor or manufacturer may be assessed, or determined, based on a per application basis for the automotive appearance care product dispensing system. The user may be charged a cost for each application the user uses the dispensing system. In one embodiment, an application may be a one-time use of the dispensing system. In some embodiments, an application may be a use of a dispensing system until the system has to be refilled with raw materials or replaced because the system has run out of raw materials. In some embodiments, an application may be a predetermined time period for use of a dispensing system (e.g., a number of days or months).
The cost per application may be based on a set rate. The set rate may be based on the average or estimated amount of fluids needed for a predetermined application using the automotive appearance care product fluids. The set rate may include other costs such as chemical or material costs, freight costs, labor costs, etc. The set rate may be based on the costs of a full use of the dispensing system (e.g., the costs associated with transporting the dispensing system to and from the site, setup of the system, raw material costs for full storage containers, and other extraneous costs such as insurance or maintenance). The set rate for an application may include cost adjustments based on the types of raw materials used in the application. The set rate may also be adjusted based on the number of dispensing systems needed by the user.
Charging a cost to the user on a per application basis may reduce the number of costs a user of an automotive appearance care product dispensing system has to track and/or monitor during use. The user may only have to budget for the cost charged by a distributor or manufacturer on a per application, or per use, basis since costs such as chemical or material costs, freight costs, labor costs, etc., are already factored into the set rate per application. The user may not need to budget separately for other costs, thereby simplifying bookkeeping, inventory, and/or other tasks associated with monitoring, tracking, or budgeting. This simplification may allow a user to operate a business (e.g., a car dealer, a detail shop, or a vehicle auction) or process more efficiently.
In certain embodiments, a user of a dispensing system may receive a statement (or bill) of charges for using the dispensing system. The statement may outline the cost for using the dispensing system on a per vehicle or a per application basis. In some embodiments, the statement may include a breakdown of the costs associated with using a dispensing system (e.g., transportation, chemical costs, etc.).
In some embodiments, dispensing of the automotive appearance care products may be substantially automated. Automatically dispensing products may reduce excess use of materials or fluids by a user of the system. Automatically dispensing products may further simplify operation of the dispensing system and the business or process utilizing the dispensing system.
In certain embodiments, a dispensing system or apparatus may include or be coupled to a counting system. A counting system may count or record numbers or amounts of one or more selected factors used in determining costs charged for use of the dispensing system. Selected factors used in determining costs may include, but not be limited to, a number of vehicles treated, a number of applications using the dispensing system, a number of uses of the dispensing system, a number of times the dispensing system is refilled, an amount of fluid dispensed by the dispensing system, or an amount of time the dispensing system is used (e.g., time the system is turned on for). The counting system may automatically count or record the number or amount of a selected factor. In some embodiments, the counting system may be manually activated (e.g., manually incremented) to count or record the number or amount of a selected factor.
In certain embodiments, the counting system may provide a report of the number or amount of a selected factor. The report may be used to determine a fee for use of the dispensing system. A statement of the fee may be provided to a user of the dispensing system. In an embodiment, the counting system may automatically determine the fee for use of the dispensing system and provide a statement of the fee to a user.
Using the embodiment in
A degreaser was produced in supply conduit 20a. The degreaser was formed by injection of surfactant from 10a, first cleaning agent from 10b, and fragrance from 10f into the water flowing from first conduit 18. Each injector 22 injected a predetermined amount of each base fluid (surfactant, first cleaning agent, or fragrance) into the flow of water. Injectors 22 were injectors manufactured by DEMA Engineering. Solenoid valve 21 controlled a flow rate of water from first conduit 18 to supply conduit 20a. An amount of degreaser dispensed was determined with metering device 25. Metering device 25 was a Fill-Rite from Tuthill Corporation. The degreaser was dispensed through exit valve 7.
Supply conduits 20b–20d operated in a similar manner producing different product fluids. An all-purpose cleaner was produced in supply conduit 20b from the injection of surfactant from 10a, first cleaning agent from 10b, and fragrance from 10f. A greater flow rate of water from first conduit 18 produced an all-purpose cleaner that was more dilute than the degreaser made from the same base fluids in supply conduit 20a.
Surfactant from 10a, foaming agent from 10c, and fragrance from 10f were combined in supply conduit 20c to form car wash soap. Surfactant from 10a, second cleaning agent from 10d, and fragrance from 10f were combined in supply conduit 20d to form a wheel cleaner. All product fluids formed in supply conduits 20a–20d were dispensed through exit valve 7. These product fluids were dispensed through the same valve 7 because of their chemical compatibility. The product fluids were dispensed at separate times through use of switches on a top panel of the housing of system 15. No system cleanup was necessary between dispensing of these fluids, although a brief initial dispensing period was beneficial to clean out fluid from the previous dispensing period. Metering devices 25 monitored a volume dispensed for each use and a total volume dispensed over time for each product fluid.
Glass cleaner from container 10e was injected into water in supply conduit 20e to form a more dilute glass cleaner. The glass cleaner was chemically non-compatible with fluids formed in supply conduits 20a–20d and therefore was dispensed through separate exit valve 8. Metering device 25 coupled to supply conduit 20e monitored a volume of glass cleaner dispensed.
