Definitions
- the present invention relates to a device for cleaning hand operated spray guns, preferably hand operated spray guns used for painting vehicles in repair shops, whereby said device includes a sealable space with holders permitting positioning of preferably one spray gun at a time in such a way relative to nozzles that said nozzles can spray solvent onto and into said spray gun for cleaning thereof, and whereby said nozzles are provided for automatic cleaning of the spray gun.
- the object of the present invention is to eliminate these problems and provide a substantially improved cleaning device. This is arrived at according to the invention by means of the characterizing features of claim 1.
- the pressurized-air system is adapted, when required, to feed solvent by means of pressurized air through a nozzle for manual cleaning, automatic as well as manual cleaning may be carried out with the one and same device.
- the cleaning device 1 illustrated in the figures is adapted for cleaning hand operated spray guns 2 or 3, preferably spray guns for painting vehicles in repair shops. Accessories to spray guns 2 or 3 and eventually other painting equipment such as brushes, tins, screens, gauge rods, etc., may also be cleaned in the cleaning device 1.
- the cleaning device 1 comprises a frame 4 with a base 5 and a lower space 6 for a tank 7 for clean solvent. A collecting space 8 is provided above the lower space 6 and above said collecting space a cleaning space 9 adapted for carrying out an automatic process for cleaning the spray gun 2 or 3.
- the cleaning space 9 is sealable by means of a door 10 which is situated in a half-open hood 11 wherein manual cleaning of the spray gun 2 or 3 may occur and which is connected to a pipe 12 in a ventilating device 77 (see fig. 10) for extraction of injurious gases from the hood 11.
- the cleaning device 1 For cleaning the spray gun 2 or 3 in the cleaning space, the cleaning device 1 includes a pressurized-air system 13 and a solvent system 14 (see fig. 4).
- the pressurized-air system 13 is through a pressurized-air conduit 15 connectable to a pressurized-air outlet (not shown) and in said conduit 15 there is provided a main valve 16 which opens when the cleaning device is set in operating condition.
- the pressurized-air system 13 includes a pressurized-air conduit 15a through which pressurized air 17 flows to a regulator 18. From said regulator 19, pressurized air 17 flows through a pressurized-air conduit 19 and a branch conduit 19a to a first time valve 20 and through a branch conduit 19b to a second time valve 21. From the first time valve 20, the pressurized air may flow through a pressurized-air conduit 22 to branch conduits 22a and therefrom to ejectors 23 for recycled solvent (see fig. 6).
- pressurized air may flow through the pressurized-air conduit 25 to a block valve 26 and if this valve is open, through a pressurized-air conduit 27 to branch conduits 27a and therefrom to ejectors 24 for clean solvent.
- the pressurized-air system 13 is controlled by a time settable control device 28.
- This control device is through a conduit 29 connected with the pressurized-air system 13 and said conduit 29 has a valve 31a which is closed at rest but openable by means of a foot pedal 31b.
- a valve 31a which is closed at rest but openable by means of a foot pedal 31b.
- pressurized air can flow through a branch conduit 29a to a pressure chamber 21a in the time valve 21.
- a check valve 30 see fig. 7 which lets through pressurized air to the time valve 20 via apertures 31 in a membrane-like valve body 32 when said valve body moves from its seat 33.
- a return spring 34 closes the check valve 30 such that the pressure chamber 20a in the time valve 20 can not communicate with the pressure chamber 21a in the time valve 21.
- a pressurized-air conduit 38 to the block valve 26 (see fig. 8) is put under pressure, the valve body 39 and spring 40 of said valve 26 being designed such that the valve body 39 engages a seat 41 and keeps the block valve 26 closed when the pressures in the conduits 38 and 25 are equal.
- the block valve 26 prevents pressurized air from flowing from the pressurized-air conduit 25 to the pressurized-air conduit 27.
- valve body 39 and spring 40 are also designed such that pressurized air in the conduit 25 is able to open the block valve 26 when the pressure in the conduit 38 ceases.
- this block valve 26 it is obtained that as long as the supply of pressurized air through the time valve 20 to the ejectors 23 for contaminated (used) solvent is open, the supply of pressurized air through the time valve 21 to the ejectors 24 for clean solvent is closed.
- the pressure chambers 20a, 21a in the time valves 20, 21 include capillary tubes 42 through which pressurized air slowly may leak out into the surroundings for obtaining atmospheric pressure in each pressure chamber 20a, 21a and thereby enable closing of the seat valve 36 by means of a return spring in cooperation with the pressure reduction across said seat valve.
- the capillary tubes 42 of the time valves 20, 21 are differently dimensioned such that the time valve 20 is open preferably for a shorter time (e.g. about 2 minutes) than the time valve 21 (which is open e.g. about 3 minutes).
- the opening time of the seat valve 36 is dependent on the length and/or through-flow area of the capillary tube 42, and this time can be determined by providing a capillary tube 42 of a certain length and/or through-flow area and changed by replacing this tube by another capillary tube 42 of different length and/or through-flow area.
- the control device 28 further includes a manometer 43, which through a conduit 44 is connected with the pressurized-air conduit 25 of the pressurized-air system 13.
- This manometer 43 is adapted to indicate when the cleaning automatism is in operation and it permits control of the air pressure in the pressurized-air system.
- the supply of pressurized air to the pressurized-air system 13 should be such that the manometer 43 shows a pressure of 5-6 bars.
- a relief valve 45 which is controlled by a magnetic body 46 located in the door 10.
- the relief valve 45 operates such that the magnetic body 46 draws a valve ball (not shown) from its seat when the door 10 is closed, which means that the relief valve 45 is kept open when the door 10 is closed.
- the magnetic body 46 is moved such that it can not retain the valve ball, but said valve is by the pressurized air brought into engagement with its seat, whereby the relief valve 45 is closed.
- the solvent system 14 includes a collecting and recycling device 47 for collecting used solvent 48 and for recycling thereof.
- the collecting space 8 for used solvent 48 forms part of the collecting and recycling device 47 and at least one suction hose 49 for feeding used solvent 48 to a suction opening 49a in the ejector 23 (see fig. 6) is inserted into said used solvent 48.
- the ejector 23 operates in a known manner, i.e. when pressurized air through the branch conduit 22a is fed through its nozzle to its venturi tube, used solvent 48 is due to the venturi effect drawn through the suction opening 49a into the flow of pressurized air and the pressurized air 50 containing used solvent 48 is discharged through at least one nozzle 51 for cleaning the spray gun 2 or 3.
- Each nozzle 51 preferably consists of a unit in which the ejector 23 for used solvent 48 as well as the ejector 24 for clean solvent 53 are included. Passages for discharging used and clean solvent 48 and 53 respectively, and forming part of said unit, extend preferably in parallel to each other.
- the solvent system 14 also includes a feed device 52 for feeding clean solvent 53 from the tank 7 to the ejector 24.
- a feed device 52 for feeding clean solvent 53 from the tank 7 to the ejector 24.
- at least one suction conduit 54 is inserted into the tank 7 and said suction conduit is adapted to feed clean solvent to a suction opening 55 in the ejector 24 (see fig. 6).
- the ejector 24 also operates in a known manner, i.e. when pressurized air through the branch conduit 27a is fed through its nozzle to its venturi tube, clean solvent is due to the venturi effect drawn through the suction opening 55 into the flow of pressurized air, and the pressurized air 56 containing clean solvent 53 is discharged through the nozzle 51 (or a separate nozzle when required) for cleaning the spray gun 2 or 3.
- the pressurized-air system 13 further includes a pressurized-air conduit 57 to an ejector (not shown) in a nozzle 58 for manual cleaning of the spray gun 2 or 3 and there is preferably provided in said conduit 57 a valve 59 which is operated by means of a foot pedal 60.
- a suction conduit 61 is preferably connected with the ejector in the nozzle 58 and clean solvent is suck through this conduit from the tank 7 to the ejector for discharging pressurized air containing clean solvent 53 through the nozzle 58.
- the nozzle 58 for manual cleaning of the spray gun 2 or 3 is preferably located in an upper space above the sealable space 9 and said nozzle 58 is preferably directed downwards towards said sealable space 9.
- the upper space with the nozzle 58 may be defined by the half-open hood 11 (see fig. 1) and said space may communicate with the ventilating device 77 for ventilation thereof.
- the nozzle 58 can preferably be provided in the sealable space 9 in such a way that the nozzle 58 is accessible when said sealable space 9 is opened.
- the nozzle 58 can be located on the underside of a lid 78 which is pivotally mounted either for closing the sealable space 9 or for being set in an upwardly directed position U such that the sealable space 9 is open in an upwards direction.
- the nozzle 58 is preferably mounted such that it directs its jets of pressurized air containing solvent in a downward direction towards the sealable space 9 when the lid 78 is set in said upwardly directed position U.
- the lid 78 preferably includes a screen 79 which screens the nozzle 58 in upwards direction and preferably also in sideways directions, whereby dispersion of unhealthy gases is obstructed.
- the nozzle 58 is preferably located on the lid 78, but may alternatively be mounted on the screen 79 or on the lid 78 as well as on the screen 79.
- a branch conduit 62 extends from the pressurized-air conduit 57 to an extraction device operated by pressurized air for sucking out or extracting injurious gases from the hood 11.
- the cleaning space 9 is provided with a yoke 63 on which the spray gun 2 or 3 can be placed, with another yoke 64 for the paint container 65 for the spray gun (the so called cup) and a yoke 66 for the cap 67 to the paint container 65.
- the cleaning space 9 is also provided with a suitable number of nozzles 51 (here at least eight nozzles) for cleaning the spray gun interiorly and externally and for cleaning the various parts of the spray gun.
- nozzles 51 here at least eight nozzles
- it can be provided with a so called extension tube 68 which is moved a distance into one of the nozzles 51 (see fig. 2).
- the pressurized air containing solvent can pass through the paint passages of the spray gun during cleaning thereof and then out through the paint discharge nozzle 70 of said spray gun.
- the spray gun 2 or 3 is placed lying down in the cleaning space 9 with its paint discharge nozzle 70 situated in front of another nozzle 51 which is adapted to direct pressurized air containing solvent towards the exterior of the paint discharge nozzle 70 for cleaning thereof.
- the pressurized air containing solvent and discharged by the nozzles 51 defines a turbulent cloud or mist of solvent in the cleaning space 9, whereby all exterior surfaces of the spray gun 2 or 3 or parts thereof are reached by the solvent.
- Fig. 3 shows that a spray gun 3 with an underlying paint container 65 can also be cleaned in the cleaning space 9. Since such a spray gun 3 has a suction tube 68a, said gun is connected by inserting the end portion of said suction tube into one of the nozzles 51. The spray gun 3 is placed lying down on the yoke 63 and the paint container 65 is put in the yoke 64.
- the collecting and recycling device 47 for collecting and recycling solvent includes a sedimentation device 71 situated in the collecting space 8 and having guide means 72 in the shape of a screen like insert (see fig. 9) which is closed on top and open at the bottom.
- the guide means 72 has a somewhat smaller outer dimension than the inner dimension of the collecting space 8 in order to define a narrow gap 73 therearound. Used solvent 48 flowing down from the cleaning space 9 is guided outwardly towards the gap 73 by the guide means 72, flows into said gap and then slowly inwards beneath inwardly directed portions 74 of the guide means 72, whereby contaminants 75 in the solvent fall to the bottom region 76 of the collecting space 8.
- the suction hose 49 (or suction hoses) of the solvent system 14 is provided to open above the inwardly directed portions 74. It is hereby prevented that the suction hose 49 can reach down into the bottom region 76 and contaminants 75 included therein. Instead, it is ensured that the suction hose 49 sucks solvent from the area above the bottom region 76.
- the ventilating device 77 is adapted to ventilate the sealable space 9 during and/or after the cleaning operation. If there is also an upper space to be ventilated, this can be done by means of said ventilating device 72 or by means of another ventilating device.
- the embodiment of fig. 10 of the ventilating device 77 includes a suction passage 80 through which the sealable space 9 communicates with the tube 12.
- this suction passage 80 there is preferably provided a filter 81 through which air containing solvent flows to the tube 12.
- This filter 81 is designed such that it separates solvent from the air flowing therethrough and it is mounted such that the separated solvent can flow back down into the sealed space 9.
- the upper space within the hood 11 is also connected with the tube 12 which in turn is connected with a fan aggregate 82 for generating sufficient air flows in the ventilating device 77 for effective ventilation of the sealed space 9 and the upper space, such that persons working at the cleaning device 1 are not subjected to injurious gases.
- the cleaning device 1 is operated as follows:
- the door 10 to the cleaning space 9 is opened and e.g. 10-15 l of solvent, preferably thinner is poured directly into said cleaning space 9.
- a tank 7 with e.g. 10 l of clean solvent 53, preferably thinner, is placed in the frame 4 and connected with the solvent system 14.
- the hand operated spray gun 2 or 3 to be cleaned, is arranged in a suitable manner in the cleaning space 9.
- the door 10 Before the cleaning automatism is started, the door 10 must be closed and then the valve 16 for the pressurized air 17 is opened.
- the cleaning automatism is started by pressing the foot pedal 31b to open the valve 31a. On the manometer 43 one can read if the cleaning automatism is operating and if the air pressure is correct. During a cleaning cycle of e.g. 3 minutes, cleaning with used solvent 48 may occur for about 2 minutes (pre-wash) and then with clean solvent 53 for about 1 minute (after-wash). When the washing cycle is finished, the pressure in the pressurized-air system 13 drops and ceases to exist when the pressurized air is cut off with the valve 16.
- this cleaning may be carried out manually by means of the nozzle 58.
- This manual cleaning is started by opening the valve 51 by means of the foot pedal 60. It is also possible to clean only the spray gun 2 or 3 or any part thereof manually by means of the nozzle 58.
- cleaning may eventually occur only with recycled solvent or only with clean solvent.
- the cleaning process may be carried out only automatically or only manually and the time periods in a cleaning cycle can be adapted to the existing requirements.
- the spray guns and/or parts thereof may be arranged in other ways than described and the device may be used for other types of hand operated spray guns then the spray guns shown and for other accessories thereto.
- the cleaning device can be designed in other ways than shown and described; the nozzles can e.g. be designed and located differently. There can be more than one nozzle 58 for manual cleaning and this or these nozzles can be located in other ways than shown. Finally, it should be noted that other solvents than thinner can be used for cleaning with the device according to the invention.
