Definitions

  • This invention relates to cleaning industrial components.
  • UK-A-1573424-and UK-A-2006913 disclose industrial component washing machines in which high kinetic energy jets of cleaning fluid having a selected pattern and orientation are each directed at a corresponding selected portion of a component to be cleaned by a respective jet which is located with precision.
  • jet assemblies selected from a series of different gripper-held jet assemblies would be used.
  • Each assembly would contain a dedicated jet designed for a specific type of washing.
  • a jet designed to form the so-called pinpoint jet of washing fluid, that is to say a jet of fluid which has a substantially uniform cross-section throughout its length, for washing blind tapped holes and small oil galleries in engine blocks.
  • jets which form a hollow cone of washing fluid and jets which form a solid cone of washing fluid for general surface cleaning.
  • Other jets which form jets of compressed air for drying would also be provided.
  • the robot would be programmed to select the jet assembly to be used, to transport the selected jet assembly to the washing location, to control it for the washing step, and then to return it to the storage location prior to selecting another jet for another washing or drying step.
  • a considerable amount of the wash cycle time was lost in the changeover operations.
  • a proposal to minimise this loss of time by arranging a number of jet assemblies as a group or cluster carried by a single robot was found to be less satisfactory than expected because of the complex form of the group or cluster and the danger of impact of parts of it with the engine block or other component being washed.
  • JA-A-58-98154 discloses alternation of the width of a paint spray pattern automatically in correspondence with the shape of an object to be painted by a spray gun carried by a robot, but paint spray apparatus is designed to form a mist of atomised paint which has low kinetic energy and is not suitable for forming a high energy jet of fluid such as is needed for cleaning.
  • GB-A-2001262 discloses a jet which may be used to form such a low kinetic energy mist of atomised fluid.
  • the pattern of the jet can be altered, it cannot be used to form a high energy hollow cone of fluid because the fluid enters the nozzle chamber in a circumferential direction to form the vortex and without an axial directional component. Also the fluid expands as it enters the chamber so that its speed falls.
  • Figure 1 shows a jet assembly 10 comprising a manifold block 11 from which a nozzle 12 projects and to which two hoses 13 and 14 are connected.
  • the nozzle 12 comprises a tubular body having a bore which reduces in diameter in three steps adjacent its end remote from the manifold 11.
  • An annular swirl plate 15 is spigotted into the larger intermediate diameter bore portion 16.
  • the central aperture 17 of the annular swirl plate 15 has a diameter which is smaller than the diameter of the smallest diameter bore portion 18 which forms an opening at the outer end of the nozzle 12.
  • the smaller intermediate diameter bore portion 19 forms a chamber 21 between the swirl plate 15 and the opening 18, the annular end wall of the chamber 21 adjacent the opening 18 tapering towards the opening 18.
  • a tube 22 is spigotted into the central aperture 17 of the annular swirl plate 15.
  • the tube 22 extends through the tubular body of the nozzle 12 and its other end is spigotted into a bore 23 in the manifold block 11.
  • the bore 23 leads to a union 24 to which the hose 14 is connected.
  • the tube 22 comprises an inner conduit which communicates with the chamber 21.
  • the major part of the tubular body of the nozzle 12, which forms the largest diameter bore portion 25, comprises an outer conduit which surrounds the tube 22 and cooperates therewith to form an annular passage leading around the tube 22 from a passage 26 in the manifold block 11 to the chamber 21, communication between the annular passage and the chamber 21 passed the swirl plate 15 being via spiral passages formed by four helical grooves in the outer cylindrical surface of the swirl plate 15 and the adjacent portions of the bore portion 16.
  • the passage 26 is connected to the hose 13 via a union 27.
  • Each hose 13, 14 is provided with a flow control valve 20 and with a solenoid shut-off valve 30.
  • the hoses 13 and 14 are connected in parallel to an output of a pump 36 which is a source of washing fluid under pressure.
  • a pressure regulator 37 in each hose 13, 14 between the pump 36 and the respective shut-off valve 30 regulates the pressure upstream of that shut-off valve 30 such that the pressure upstream of the valve 30 in the hose 14 is higher than that upstream of the valve 30 in the hose 13.
  • a supply of compressed air having its own shut-off valve 38 and pressure regulating valve 39 is connected to the hose 14 between the shut-off valve 30 in the hose 14 and the union 24.
  • Figure 2 shows that the nozzle 12 forms a hollow cone spray when washing fluid is supplied through the annular passage and the spiral passages formed by the swirl plate 15 to the chamber 21, the shut-off valve in the hose 14 being closed so that no fluid is supplied via the tube 22.
  • Flow through the spiral passages imparts a spinning action to the fluid so that it enters the chamber 21 with such a spinning action and with an axial directional component and forms a vortex in the chamber 21 which causes formation of the hollow cone.
  • Figure 3 shows that a pinpoint jet of washing fluid is formed when washing fluid is supplied to the opening via the tube 22 only, the shut-off valve in the hose 13 being closed so that no washing fluid is supplied by the annular passage and the spiral passages to the chamber 21.
  • Figure 4 shows that a full cone is formed when washing fluid is supplied by both the tube 22 and the annular passage and the spiral passages to the chamber 21, the two supplies of washing fluid interacting in the chamber 21 to form the full cone.
  • the spinning flow that emerges from the spiral passages into the chamber 21 with an axial directional component spins around the substantially uniform cross-section stream that emerges from the tube-22 in an area of the chamber 21 which has substantially the same cross-sectional area of the four spiral passages.
  • the flow emerges from the spiral passages into the chamber 21 without significant loss in kinetic energy (this is the case also when a hollow cone spray pattern is formed as illustrated in Figure 2). It is necessary to regulate the flows through the two paths by adjustment of the respective flow control valves in order to obtain the optimum spread of the full cone.
  • a compressed air jet is formed when the shut-off valves 30 in the two hoses 13 and 14 are closed to shut off the supply of washing fluid and the compressed air supply is opened by opening its respective solenoid shut-off valve 38 so that compressed air is supplied through the tube 22 to the opening 18.
  • the jet assembly 10 When the jet assembly 10 is used to wash an industrial component, such as an engine block, by a method in which this invention is embodied, it may be mounted on an arm of a robot which is programmed to effect a sequence of movements of the arm automatically whereby the jet assembly 10 is located and oriented automatically at each of a programmed sequence of locations and orientations in space, the program being appropriate for the components to be washed and the robot being located adjacent a washing station at which each of a series of the components to be washed is located in turn for washing.
  • an industrial component such as an engine block
  • the robot controls operation of the solenoid-operable shut-off valves 30 to effect the required supply of washing fluid to the chamber 21 via the annular passage and the spiral passages, or the tube 22 or both, dependent upon the form of washing fluid jet required for the particular washing operation to be performed in accordance with the program, or to effect closure of the two washing fluid shut-off valves 30 in the hoses 13 and 14 and to open the compressed air supply shut-off valve 38 for the drying steps of the washing cycle.
  • the compressed air supply as described would function to displace washing fluid that had accumulated in the nozzle 12, it may be desirable to provide a form of venting to clear washing fluid from the nozzle 12 for the drying step.
  • the robot may be adapted to control operation of the nozzle 12 to effect pulsing of the washing fluid jet supply during a washing step if desired.
  • a supply of compressed air having its own shut-off 38A valve and pressure regulating valve 39A may be connected to the hose 13 between the shut-off valve 30 in the hose 13 and the union 27 instead of or in addition to the supply of compressed air connected to the hose 14.
  • the pattern of the jet of compressed air may be varied automatically if desired by controlled operation of the respective shut-off valves 38 and 38A in much the same way as has been described above with reference to Figures 2, 3 and 4 when the shut-off valves 30 in the hoses 13 and 14 are closed to shut-off the supply of washing fluid.
  • FIG. 5 shows an industrial parts washing machine comprising a housing 40 with a loading hatch 41 through which a component to be washed is passed into and withdrawn from a work station within the housing 40.
  • a turntable 42 at the work station.
  • a number of fixed jet assemblies 43 are located and orientated with precision around the work station.
  • a robot 44 is provided within the housing 40.
  • FIG 6 shows the robot 44 in more detail. It carries a jet assembly 45 at the end of its arm.
  • the configuration and construction of each jet assembly 43, 45 is as has been described above as the jet assembly 10 with reference to Figures 1 to 4.
  • the machine includes a control panel 46 which is interlinked with the robot 44 and which incorporates programmed control means for controlling operation of the fixed jets 43 as well.
  • the programmed control means are microprocessors and such microprocessors may be incorporated in the robot 44 as well.
  • a component to be cleaned is conveyed to the loading hatch 41.
  • An automatic door of the hatch 41 is opened to allow the component to be introduced into the interior of the housing 40 and be loaded on the turntable 42.
  • the automatic door of the hatch 41 closes automatically once the component is positioned and locked on the turntable 42.
  • the programmed control means incorporated in the control panel 46 and in the robot 44 select the appropriate robot control program signal and instruct the robot control system to commence the wash cycle.
  • the robot 44 washes one face and 25% of the top of the work envelope of the component and returns to a safe location within the enclosure 40.
  • the pattern of the jet of fluid directed at the component by the jet assembly 45 and the wash action are controlled directly from the robot microprocessor and are therefore totally integrated into the robot program.
  • Figure 7 shows operation of the jet assembly 45 to direct a pinpoint jet of washing fluid at a selected part of the component.
  • Figure 8 shows the jet assembly 45 directing a cone spray of washing fluid at the component.
  • the turntable 42 is now indexed through 90 0 and through this operation the static jet assemblies 43 are operated in accordance with the program of the programmed microprocessors in the control panel 46 to remove gross swarf content from the component.
  • the robot 44 is instructed to continue the cleaning cycle on the next face and part of the top of the component. This cycle is continued until each side has received a robot wash and the overall component has received four flushes.
  • a drying cycle then commences, including direction of compressed air by the jets 43 and 45 onto the component.
  • the robot 44 operates to effect drying of the nearest face of the component in a similar manner to the washing operation.
  • General drying is effected by operation of blower fans incorporated in the housing 40 whilst the turntable 42 is indexed.
  • the blow-off fans are stopped, the supply of compressed air to the jet assemblies 43 and the robot jet assembly 45 is stopped by appropriate operation of the compressed air shut-off valves 38.
  • the automatic door of the loading hatch 41 opens and the component is removed.
  • Figure 9 shows an alternative arrangement in which the present invention is embodied.
  • a manifold 28 carries two nozzles 29 and 31.
  • the construction of each nozzle 29, 31 is substantially similar to the construction of the nozzle 12 described above with reference to Figure 1 and the connections through the manifold 28 of each nozzle 29, 31 to the respective pair of hoses 32 and 33, 34 and 35, are substantially similar to the equivalent connection of the nozzle 12 to the respective pair of hoses 13 and 14 as described above with reference to Figure 1.
  • the axis of the nozzle 31 is oblique to the axis of the nozzle 29 so that jets emitted from the two nozzles 29 and 31 converge.
  • the outer end of the nozzle 29 is further from the manifold 28 than is the outer end of the nozzle 31.
  • the manifold 28 is mounted on the arm of a robot.
  • the washing operation is substantially as described above with reference to operation of the nozzle 12.
  • the arrangement of the two nozzles 29 and 31 increases the scope of the washing operations that can be performed.
  • the space between two portions of a surface that can be washed by the jet assembly shown in Figure 9 can be increased by moving the two nozzles 29 and 31 closer to that surface, or can be reduced by moving the nozzles 29 and 31 further away. This is because the jets converge.
  • the nozzle 29 can be effectively shut off so that washing is effected only by the nozzle 31 by bringing the nozzles so close to the surface being washed that the surface abuts the outer end of the nozzle 29.
  • the jet assemblies described above with reference to Figures 1 to 4 or 9 may be designed so as to be physically and functionally compatible with a machine installation as illustrated in Figure 10 which includes a robot 50 which is arranged to select and locate automatically at a work station 51-54 one of a group of different tools, whereby the jet assembly is one of the group 55 of tools available for automatic selection.
  • the jet assembly may be formed with a shank or other suitable connecting and locating means adapted to locate the jet assembly at the work station 51-54 and to connect the jet assembly to a source of fluid pressure of the machine, the jet assembly being usable for various cleaning purposes, e.g. removal of debris or contaminants, such as swarf and oils.
  • the normal coolant/fluid available for use during the operating cycle of the machine could be directed through the jet for such purposes.
