Description

241 1 824 Cleaning Apparatus
Field of the Invention
This invention relates to cleaning tools, and in particular to an apparatus for cleaning spray guns.
Background of the Invention
Paint spray guns are widely used in automotive repair shops and other industries where spray painting is carried out. 'I'hese spray guns must be cleaned regularly if they are to have a reasonable service life. Furthermore, spray guns must be thoroughly cleaned within a limited time frame following use, otherwise the paint tends to solidify, making the spray gun exceedingly difficult to clean.
There are many examples of spray gun cleaning apparatus. The most commonly used apparatus comprise a cabinet which includes a drain, a fluid supply, a fluid dispersion means and fluid collector.
The fluid supply and fluid collector are consumables, brought to and removed from the machine.
The spray gun cleaning apparatus must itself be cleaned periodically. This gives rise to a number of problems. First, whilst the apparatus is being cleaned, it is not possible to use the same apparatus for cleaning spray guns, and hence spray gun operators may be forced to stand idle whilst waiting to clean their spray guns. Second, spray guns and ancillary equipment must be cleaned within 10 minutes of ceasing spraying. If an operator has to wait longer than this threshold time, the paint in his gun may "go of P', making the gun particularly difficult to clean. Third, because the spray gun cleaning apparatus must be dismantled for cleaning, only a properly trained service engineer can carry out the cleaning operation. Fourth, because known spray gun cleaning apparatus require on site cleaning, the number of apparatus that a service engineer can attend to in any one day is limited by the amount of time he must spend cleaning apparatus. Fifth, the cleaning agents used to clean the apparatus must be acceptable for use in a spray shop.
A number of patents and patent applications relate to spray gun cleaning apparatus. W097/3567 describes equipment for cleaning spray guns in which an electric pump is used to convey cleaning liquid to an through spray nozzles.
Another known spray gun cleaning apparatus is described in US (>,(47,997. The apparatus described in this patent is characterised in not requiring hand operation of taps and the like.
Another known spray gun cleaning apparatus is described in US 4,827,955. In this patent, a suction system is used to expose the spray gun to a vacuum for cleaning. This apparatus avoids solvent being sprayed into the atmosphere.
A spray gun cleaning apparatus is also known from US 20()4/0103933. In this patent the apparatus is characterised by the washer apparatus providing clean solution throughout each wash cycle.
Another spray gun cleanh1g apparatus is described in BP 1327485. In this patent the apparatus is characterised by the presence of a partially submerged rotatable brush.
None of the spray gun cleaning apparatus described in the above-mentioned patent intormauon addresses the problems previously set out.
It would therefore be desirable to provide an improved cleaning apparatus, which is suitable for the cleaning of spray guns.
Summary of the Invention
According to one aspect of the invention there is provided a cleaning apparatus as specified in Claim 1.
According to a second aspect of the invention there is provided a method of cleaning spray painting equipment as specified in Claim 22.

Detailed Description of the Ptefetted Embodiments
Referring now to ligures la and lb, a cleaning apparatus I comprises a cabinet structure 2 upon which a cleaning tank 3 is removably mounted. The cabinet structure 2 further includes a thinners store 4 covered by a removable plate 5. The removable plate 5 includes a handle 6 and four spaced apart key hole slots 7, which co-operate with pins mounted on the cabinet structure 2 to hold the removable plate in place. Mounted on one side of the cabinet structure are compressed air services in the form of a hose connection 9 for connection to a supply of compressed air (not shown) and a compressed air gun 10 connected to a compressed air outlet 11 by means of a flexible hose 12. The cleaning apparatus 1 further includes an extractor unit 8, which is described in greater detail with reference to Figures 7a to 7c. In Figure 1 a the lid 13 of tank 3 is open, whereas in Figure lb the said lid 13 is closed.
The lid 13 is held in the lifted position illustrated in Figure l a by means of engagement between sides 14 of said lid 13 and a clip 15. The sides 14 are fabricated from a material having at least some resilience. 'l'he lid 13 is fabricated such that the in the dosed position illustrated in Figure lb the sides 14 press against sides 17 of the tank 3. As the lid is opened, the sides 14 ride over the bracket 15. When the edge 18 of the side 14 has passed over the bracket 15, the said edge 18 is aligned with an opening provided by the bracket. 'lthe lid 13 is then pulled slightly as if to close said lid 13, bringing the edge 18 into engagement with the bracket 15.
Also shown in l'igure la is the switch bank 80, which includes a hand wash switch 81, a clean rinse switch 82, a timer switch 84 (see Figure 2d) , and cover plate 83 to protect the switches from unintentional switching.
Figures 2a to 2d illustrate the steps for removing the tank 3 from the cleaning apparanus 1.
In Figure 2a the tank is situated in the cleaning apparanus with the lid 13 closed.
In Figure 2b the lid 13 is shown removed from the cleaning apparanus 1. In the sides 17 of the tank 3 are provided with slots 1') in which pins 20 of the lid 13 locate.
In Figure 2c the tank 3 is in the process of being removed from the cabinet structure 2. Removal of the tank 3 is achieved by pulling the lower front part of the tank 3 forwards and upwards so that the tank rotates about a point X where the tank 3 engages with the extractor unit 8. As the tank rotates a corner 21 of the tank slides on a track 24 of the cabinet structure 2.
In Figure 2d the tank 3 is fully removed from the cabinet structure 2. The tracks 24 on which the base 26 of the tank 3 slides and rests are formed from angle sections, with the leading edge of each track 24 being provided with a chamfer 25 to facilitate easy alignment of the tank 3 to the cabinet structure 2 when re-fining the tank 3 to the cabinet structure 2. A ledge 23 is provided in the upper rear part of the tank 3. '[this ledge 23 engages with the tmderside of the extractor 8 to provide an effective seal between the tank 3 and the extractor 8 when the cleaning apparatus 1 is in the configurations illustrated ill Figures 2a and 2b.
Referring now to Figures 3a to 3d, there is shown a stack of three tanks 3. In Figure 3a the tanks 3 are shown spaced apart. Invoking at the middle tank 3 in Figure 3a, it can be seen that the wall 17 extends beyond the upper surface of lid 13 by a small distance. In the configuration shown in Figure 3c, the upper tank 3 sits on the middle tank 3, which in Burn sits on the lower tank 3, the base 26 of a s tank 3 sitting on the did 13 of the tank 3 below. A tank 3 stacked on top of another tank 3 is constrained from lateral movement by the extension of walls 17 beyond the upper surface of lid 13.
F.ach tank 3 that is stacked on top of another tank 3 is constrained from longitudinal movement by pins 22 which engage with the slots 19 previously described with reference to Figure 2b. The slots 19 therefore fulfil dual functions. First, they form part of the lid hinge, and second they provide for the safe stacking <>f the tanks 3.
lthc tank 3 is illustrated in greater detail in Figures 4a to 4c. Rcfctring now to Figure 4b, the tank 3 comprises a chassis 27 strengthened by substantially U shaped members 28 disposed adjacent walls 17 of the tank 3. 'I'he width of these U shaped members corresponds substantially to the width of tracks 24, and it is the lower parts of the U shaped members that rest on the said tracks. 'lthe chassis 27 mounts a base plate 33 in which a drain 32 is located. Located in each corner of the tank 3 is a pipe 34 having outlet nc>zzlcs 35 (numbered on one pipe only for the sake of clarity). Each tube 34 is fluidly colmectcd to a tube mount 36. A perforated plate 29 rests on the tube mounts 36 such that a void exists between the perforated plate 29 and the base plate 33. The perforated plate 29 is provided with edge formations 30, 31 which essentially consist of folded metal, and serve to strengthen the said plate. In use a piece of filter material is place on beneath the perforated plate 29, and another perforated plate is placed beneath the filter material. Fluid exiting through the nozzles and 37 passes through the first perforated plate 29, through the filter matcriaL and the second perforated plate to gather on base plate 33 to exit through drain 32.
Referring now to Figures 5a to 5e, drums 40, 41 arc located in the fluid store 4. In this embodiment drum 40 contains unused clean thinners fluid, whereas drum 41 contains used dirty thinners fluid. In operation, the used thinners fluid contained in drum 41 is recycled and re-used for the first part of a cleaning cycle, and the clean thinners fluid from drum 40 is used for the final rinse cycle. When the cleaning apparatus is serviced, the old drums 40 and 41 arc removed, with the old drum 40 that has been removed becoming the new drum 41, and a new dmrn 4() is installed. 'I'he new drum 4() and old drum 40 (new drum 41) are each approximately half full. A pipe 42 extends from the chum 4() to a shut- off valve 43, which is in fluid connection with a pipe 44 that is connected to a clean rinse nozzle (see Figure 8) the pipes 34. A pipe 45 extends from the dnm 41 to a shut-off valve 46, which is in fluid connection with a pipe 47 that is connected to the pipes 34. Another pipe (not shown) extends from drain 32 to the drum 40.
Referring now to Figures 6a to 6c, the cleaning apparatus l includes a hose connection 9 for connection to a supply of compressed air (not shown) to the apparatus. Compressed air is the power source for the apparatus as will be described in greater detail with reference to Figure 9. The apparatus also includes an air gun 10 connected to a compressed air outlet 11 by means of a flexible hose 12. The air gun is provided as many spray gun operators like to use compressed air to assist in cleaning their spray guns. As is best shown in Figure 6c, the air gun 10 includes a hook 48, which hooks onto a cc>rresponding hook 49 protruding from the cabinet structure 2. 'lihe air gun is conveniently positioned for use by an individual using the cleaning apparatus 1.
Figure 7a to 7c illustrate the extractor unit 8 which comprises a housing 50 on top of which is mounted a chamber 51 having an outlet 52. in the assembled cleaning apparatus 1, the housing 50 lies above the rear part of the cleaning tank 3. The housing 50 includes a pair of spaced apart apertures 57 which receive tubular elements extending d<>wnwardly from the housing 5(). Seals 61 ensure that air extracted from the tank 3 does not leak into the housing 50.
Extraction of air from the tank 3 is achieved by means of an air jet 60. 1'he air jet 6() is connected to the supply of compressed air by means of pipe 54. The air jet 60 functions as a venturi, cleating a region of high velocity and low pressure air at the top of the chamber 51. '[this has the effect of drawing Sir in the tank through the chamber 51 and out of the outlet 52.
The housing 5() includes an element 58 which mounts a cut-off switch 59. 'lthe cut-off switch 59 is on when the lid 13 is up, because any contamination can escape to atmosphere, and off when the lid 13 is down. 'lihe switch 59 is turned on and off by engragement/disengagement of a part of the lid 13 with the switch 59.
Reherung now to Figure 8, the cleaning fluid circuit comprises a chum 40 containing clean thinners fluid and a drum 41 containing recycled thinners fluid Inlets of two pumps 71 and 73 are connected by pipes 72 and 74 respectively to the drum 41, each pipe 72, 74 having a filter 7() at the drum end.
Rach pump 71, 73 has an outlet connected to a nozzle located ha the tank 3. The pump 71 is connected by a pipe 75 to connectors 76 which attach to pipes 34 to deliver fluid to nozzles 35 and 37. The outlet of pump 73 is comlected to a hand wash nozzle 77, which, in use, is located in the tank 3 towards the rear thereof.
lihe drum 40 containing clean thinners fluid is connected by a pipe 42 to a clean rinse nozzle 78, which, in use, is located in the tank 3 towards the rear thereof. Clean thinners fluid is drawn from the drum 4() to the nozzle 78 due to a partial vacuum created in a chamber in the clean rinse block by the admission of air through a jet in the same clean rinse block when the tank lid is open and the clean rinse switch 82 is operated.
Outlet 32 of the tank 3 is fluidly connected to the drum 41 by means of a shut off valve 79. For most cleaning operations the shut off valve 79 is open so that spent cleaning fluid that has passed through the filter elements in the base of the tank 3 return to the thinners fluid drum 41. Ilowcvcr, one cleaning operation involves soaking items placed in the tank 3. In order to run this cycle the valve 79 must be closed.
Referring now to Figure 9, the pressurised air system includes: a compressed air supply connection 9, the pumps 71 and 73, both of which are powered by compressed air, an on/off valve 85, an air kilter 86, an air gun 10, a timer valve 84, a hand wash switch 81, a dean rinse switch 82, an pressure regulator valves 87 and 88.
In use, with the a compressed air supply attached to the connection 9, the on/off valve 85 is opened and air flows through the kilter 86 to supply the air gun 10 and the switch 59. When the lid is open, the switch 59 is OpCII and compressed air flows to the nozzle 60 and to the hand wash switch 81. If the hand wash switch 81 is opened, air flows via pressure regulator 87 to the pump 73, thereby pumping thinners fluid from the drum 41 to the hand wash outlet nozzle 77. Similarly, with the lid open and the switch 59 open compressed air is delivered to the clean rinse switch 82. When the clean rinse switch 82 is opened, air is allowed to pass to the clean rinse outlet 78 and within this outlet through a jet and into a chamber. A partial vacuum is created in the chamber drawing thinners fluid from the clean thinners drum 40 into the chamber, where it is atomised and forced out of the clean rinse outlet 78.
With the switch 59 dosed, compressed is prevented from flowing to the nozzle 60 and handwash switch 81. In this condition the extraction system is switched off, and pump 73 does not operate.
Compressed air is delivered to the timer valve 84, through a pressure regulator 88 and then to pump 71. In use, an operator sets the timer valve to give a particular period of wash, e.g. 45 seconds. The timer valve allows compressed air to pass thcrethrough for the selected wash period resulting in the pump 71 pumping thinners fluid from the drum 41 to the nozzles 35, 37 for the selected period. At the end of the selected period the timer valve 84 prevents further passage of compressed air and the pump ceases operation.
Operation of the cleaning apparatus is as follows: An operator opens the lid 13, opening switch 59 thereby activating the extraction system, the manual wash and clean rinse functions. To use the manual wash the operator switches switch 81 to the "on" position. When the manual wash is finished the operator switches switch 81 to the "off" position.
To use the clean rinse function the operator switches switch 82 to the "on" position. When the clean rinse is finished the operator switches switch 82 to the "off" position. The extraction system continues extraction until the lid 13 is closed.
Where an operator wishes to use the automatic mode, he closes the lid 13 and sets the timer 84, which causes thinners fluid to be delivered to the outlet nozzles 35, 37.
To operate in "soak" mode, the operator closes shut-offvalve 79. Any of the "automatic", "manual wash", and "clean rinse modes" can be used in "soak" mode.
The cleaning apparatus of the invention is particularly advantageous as it allows the apparatus to be cleaned away from the place where the apparatus is located. This is achieved by having a tank 3 which is detachable from the rest of the machine. This provides a number of advantages: First, the apparatus downtime is reduced from around 30 to 45 minutes to 5 to 10 minutes, resulting in less down time for spray gun operators. Second, because the time taken to service the cleaning apparatus is only 5 to 10 minutes compared to around 30 to 45 minutes for known apparatus, a service engineer can service many more machines in a day. Third, the actual operation of cleaning a tank does not require a person having the same skill level as a service engineer. As such the cost of cleaning can be reduced by using labour having a skill level appropriate for the task in hand.
Furthermore, in one embodimcut of the invention a simple stacking system is provided. This is beneficial for both said transportation and storage of the tanks.
Additionally, another embodiment of the invention provides a convenient means for holding the tank lid in its open position.
