DETAILED DESCRIPTION
[0033] Referring to FIGS. 1-6 the first embodiment defined as a pressurized adjustable automatic mixing and dispensing apparatus or dispenser 20. The apparatus 20 has a lubrication concentrate (cutting oil or fluid) input 22, a lubrication concentrate output 24, a water input 26 and a water output 28. A mixing manifold 30 is provided below the concentrate output 24 and the water output 28 to mix the solutions (concentrate and water) together in the mixing manifold 30 from which the mixed fluid is fed into dispenser output 32 and further into a bucket 9 or reservoir sump 8 via a hose 7. The dispenser unit 20 has a power up button 36 and an external power outlet 38 for an external concentrate self-priming pump 3 mounted on the concentrate drum 2. A concentrate empty buzzer 40 is located on the dispenser 20 to indicate when the concentrate barrel 2 is empty, as known by the control 46 from past usage. The dispenser 20 is controlled by the touch screen control 46 which is programed and further programmable by its touch screen control 46. A bucket light 42 is also provided to be illuminated when the dispenser 20 is filling a bucket 9.
[0034] FIG. 2 illustrates the use of the dispenser 20 with a water input 1 and a pressurized concentrate input 5. The water is simply pressurized water from any source such as city or a well which feeds into water input 26 into the dispenser 20. The concentrated cutting oil is sourced from drum 2 which has an oil self-priming transfer pump 3 which pumps cutting oil out of the drum 2 and into concentrate input 22 into the dispenser 20. The touch screen control 46 allows the operator to set the volume of the mixed cutting and cooling fluid at a certain desired ratio. Viewing the concentrate side of the dispenser 20 from the inside of the dispenser 20 (FIG. 4) a concentrate conduit 50 receives the concentrate and the volume is controlled by the open and closed solenoid valve 52 under the control of the touch screen control 46 which receives the volume passing through the dispenser 20 from the flow meter 54. Viewing the water side of the dispenser 20 from the inside of the dispenser 20 (FIG. 4) a water conduit 60 receives the water and the volume is controlled by the open and closed solenoid valve 62 under the control of the touch screen control 46 which receives the volume passing through the dispenser 20 from the flow meter 64. Two fluids exit the dispenser through concentrate output 24 and water output 28 into mixing manifold 30 and then through hose 7 into machine 6 sump 8 for use by the CNC machine 6 in premeasured volume and concentrate.
[0035] FIG. 3 illustrates the use of the dispenser 20 with water input 1 and a pressurized concentrate input 5. The water is simply pressurized water from any source such as city or a well which feeds into water input 26 into the dispenser 20. The concentrated cutting oil is sourced from drum 2 which has an oil pressurizing transfer pump 3 which pumps cutting oil out of the drum 2 and into concentrate input 22 into the dispenser 20. The touch screen control 46 allows the operator to set the volume of the mixed cutting and cooling fluid at a certain desired ratio. Viewing the concentrate side of the dispenser 20 from the inside of the dispenser 20 (FIG. 4) a concentrate conduit 50 receives the concentrate and the volume is controlled by the open and closed solenoid valve 52 under the control of the touch screen control 46 which receives the volume passing information through the dispenser 20 from the flow meter 54. Viewing the water side of the dispenser 20 from the inside of the dispenser 20 (FIG. 4) a water conduit 60 receives the water and the volume is controlled by the open and closed solenoid valve 62 under the control of the touch screen control 46 which receives the volume passing information through the dispenser 20 from the flow meter 64. Two fluids exit the dispenser through concentrate output 24 and water output 28 into mixing manifold 30 and then through hose 7 into a bucket 9 for manual loading into the CNC machine 6 sump or reservoir 8 in premeasured volume and concentrate.
[0036] FIG. 5 illustrates the operation flow chart of the dispenser 20 in FIGS. 2 and 3. The touch control 46 of FIG. 6 illustrates options for volume and mixing ratios of the concentrate and water to be chosen by the operator. Illustratively, five pre-set programs may be available for the operator. The top number of each program is the volume to be dispensed and the bottom number of each program is the percentage at which to mix the concentrate into the water. For example, for program 2, if you were to dispense 10 gallons total at a 5% mix ratio, you would dispense gallon of oil on the concentrate side and 9 gallons of water on water side. The two fluids would come together in the mixing block 30 that hangs below the unit. The fluids are mixed there, then continue into whatever reservoir you are dispensing into, whether it be a bucket 9 or a sump tank 8.
[0037] FIGS. 7 and 8 illustrate a second embodiment of a premixed fluid one input adjustable automatic dispensing apparatus or dispenser 60. The dispenser 60 has an internal conduit 61 in flow communication with pre-mixed lubrication concentrate (cutting oil) and water inlet 62 and pre-mixed lubrication concentrate and water outlet 64. Conduit 61 has a solenoid valve 65 and a flow meter 66. The dispenser 60 further has a power button 67, a self-priming pump power outlet 68, fluid source empty buzzer and a bucket light 72. A touch screen control 74 is provided along with a power supply 76 and a relay 78 for energizing a self-priming external pump 3 on the drum 2
[0038] FIG. 9 illustrates the use of the dispenser 60 with a pre-mixed concentrate and water solution with CNC machines 6. Pre-mixed remote solution from a central mixing station is fed to dispensers 60 through conduit 10 into the dispensers' solution input 62. The dispenser 60 is connected to an electrical power source 76. The power button 67 is pushed to energize the dispenser 60 and to turn on the touch screen control 74. The operator puts in the volume of pre-mixed cutting and cooling solution suitably in gallons and presses the run button on the control 74. The solenoid valve 65 opens up to allow flow of the solution while the flow meter 66 counts the volume of fluid passing through the dispenser 60, into pre-mixed solution output 64 into reservoir or machine sump 8 via hose 7 until the desired amount has been delivered when the control 74 closes the solenoid valve 65.
[0039] FIG. 10 illustrates the dispenser 60 with a bucket 9 application with an external self-priming pump 3. The drum 2 contains a pre-mixed concentrate and water solution. The dispenser 60 is supplied with electrical power 76. The operator pushes the power button 67 to energize the dispenser 60 and the touch screen control 74 wakes up. The relay 78 energizes the pump 3 through outlet 68. The operator puts in the desired volume of pre-mixed cutting and cooling solution suitably in gallons and presses the run button on the control 74. The solenoid valve 65 opens up to allow flow of the pre-mixed solution while the flow meter 66 counts the volume of fluid passing through the dispenser 60, into pre-mixed solution output 64 into the illuminated bucket 8 via hose 7 until the desired amount has been delivered when the control 74 closes the solenoid valve 65.
[0040] FIG. 11 illustrates the dispenser 60 with a bucket 8 application. A pressurized water supply 1, a pre-mixed drum 2 with mixed solution and a venturi mixing valve 13. The water is connected to the venture valve 13. The dispenser 60 is supplied with electrical power 76. The operator pushes the power button 67 to energize the dispenser 60 and the touch screen control 74 wakes up. The operator puts in the desired volume of pre-mixed cutting and cooling solution suitably in gallons and presses the run button on the control 74. The solenoid valve 65 opens up to allow flow of the pre-mixed solution while the flow meter 66 counts the volume of fluid passing through the dispenser 60, into pre-mixed solution output 64, hose land then into the illuminated bucket 9 until the desired amount has been delivered when the control 74 closes the solenoid valve 65.
[0041] FIG. 12 illustrates the operation flow chart of the second embodiment 60 of the premixed fluid one input adjustable automatic dispensing apparatus or dispenser 60.
