Abstract

In order to clean objects, in particular paint spray guns, with a liquid cleansing agent, the parts are introduced into a basket (44) rotatively mounted around a vertical axis within an airtight cleaning chamber (44). A pump (84) driven by a compressed-air motor (86) sprays the cleansing agent through spraying nozzles (67, 69) on the parts to be cleaned, thus rotating the basket. The spray gun bodies held in supports in the basket (56) are rinsed with cleansing agent sprayed through their paint inlets and supplied by a branch pipe (58) and adapter (72a, 72b) arranged across the axis of the basket. The used cleansing agent is returned through a filter (42) to a container (36). Another container (34) contains unused cleansing agent. For a first, rough cleaning, the pump (84) supplies used, filtered cleansing agent. For the final cleansing the unused cleansing agent is supplied. After the final cleaning, compressed air is blown into the cleaning chamber (44) and at the same time the air containing cleaning agent vapours is extracted from the cleaning chamber (44) through a venting nozzle (46) by a compressed-air injector (112). The process is automatically controlled, if necessary with a full cleaning option and a rough cleaning option followed by drying.

Description

 Method for cleaning objects using a liquid cleaning agent and device for automatically carrying out the method.

The invention relates to a method for cleaning objects using a liquid cleaning agent, in particular for cleaning the exterior and interior of paint spray guns with a trigger mechanism, a paint cup provided with a removable lid and an air nozzle, the cleaning agent being pumped a cleaning agent pressure line is conveyed into a cleaning chamber and is sprayed or sprayed onto the surface of the parts to be cleaned for external cleaning or is passed through the paint feed channel of the spray gun for internal cleaning, the cleaning agent being collected at the bottom of the cleaning chamber and via a filter is fed to a container for filtered cleaning agent and is first cleaned with filtered cleaning agent and then cleaned with new cleaning agent, and a device for automatically carrying out the method.

It is known that paint spray guns must be cleaned of paint residues before each use. The cleaning is done using a cleaning liquid, primarily a wash dilution, which is a mixture of organic solvents such as alcohols, ketones, acetates, aromatics and petrol. Since these color-dissolving cleaning agents have a flash point below 21 ° C., the corresponding cleaning devices must comply with the provisions on explosion protection.

Almost all cleaning devices on the market work in such a way that the paint spray gun is held with the hands of the person performing the cleaning in a cleaning chamber that is open to the front during the cleaning process, the exterior cleaning of the spray gun being carried out under a spray shower, which is then manually performed The interior of the paint-carrying parts of the spray gun is cleaned by first filling the paint cup with a little cleaning fluid and then operating the spray gun in the usual way with compressed air, so that the cleaning fluid injects the internal paint contamination into the cleaning chamber.

The paint cup with lid and the air nozzle unscrewed from the spray gun or the other built-in parts must be individually manually exposed to the spray shower. The hands of the person performing the cleaning are wetted by the cleaning liquid which is harmful to health, and the damaging vapors are also inhaled, even if the cleaning chamber, which is open to the front, is connected at the rear or at the top to a suction device.

After the cleaning process, the spray gun and accessories must be dried manually. A device is now known in which the paint-soiled spray guns with cup and accessories are placed or fixed in a closable cleaning chamber, several spray nozzles being arranged in the interior of the cleaning chamber, via which the parts to be cleaned outside and be wetted inside. This device works with a single circulating cleaning liquid which is already contaminated by the color components which have passed into solution after the first cleaning process and which can only be cleaned of the solid color components by filtering. In addition, the cleaning agent rests here on a cushion of water, which is contaminated and must be disposed of.

A disadvantage of this device is also that the parts must be dried manually after cleaning and that after opening the cleaning chamber to remove the parts, the solvent vapors inside escape into the work area.

The following disadvantages thus result both in manual cleaning and in the use of the known cleaning device:

- damage to hands and skin,

- Inhalation of harmful solvent vapors during or at the end of the cleaning process and

- Lack of automatic drying after cleaning.

In manual cleaning there is also a relatively large consumption of cleaning agents because of the - -

uncontrolled course of the cleaning process disadvantageous.

The invention is based on the object of providing a cleaning method and a device suitable therefor, which make it possible to overcome the disadvantages mentioned and to carry out a fully automatic cleaning with as little effort as possible while observing all safety regulations. In particular, the aim is to ensure that people neither come into contact with the cleaning liquid nor inhale their vapors, that at the end of the cleaning process the spray guns or parts are completely dried and available for immediate assembly, that the cleaning liquid is used economically is guaranteed and in particular simple disposal can take place.

Since it has hitherto been customary in manual cleaning not to carry out a complete and thorough cleaning of the spray guns after each color change, but rather only a rough cleaning using filtered, already used cleaning agent, the method and the device should also be suitable, if desired, to carry out either such a preliminary cleaning or a complete cleaning with a final cleaning using a new cleaning agent.

Furthermore, the method and the device should be designed in such a way that the individual method steps, namely the pre-cleaning, the final cleaning and the drying, can be changed within given limits with regard to their duration, in order to adapt to the cleaning requirement in each case optimally to allow. To achieve this object, the method mentioned at the outset is designed such that at least one spray gun with the air and / or paint nozzle removed and the paint cup removed is positioned in a basket rotatably arranged about a vertical axis in the cleaning chamber, one connected to the detergent pressure line, through the hollow axis of the basket branch line is connected via a hose line and an adapter to the paint access opening of the spray gun, that the paint cup with the cover removed is fixed with the opening down in the basket and the cover in ge ¬ inclined position is positioned in the basket, that the removed air and / or paint nozzle and if necessary also other ink-wetted parts of the spray gun are housed within the basket, that the cleaning chamber is then closed tightly and the pump is then driven by a compressed air motor and the detergent Via the detergent pressure line to the branch line and sprayed against the basket from below the basket and laterally next to the basket over its height, spray nozzles are sprayed, the pump from this container for filtered detergent and in a first cleaning cycle second cleaning cycle promotes new detergent from a second container into the detergent pressure line and that compressed air is fed into the cleaning chambers in one drying cycle and that vapors are removed from the cleaning chamber via a vent during drying.

As a result of this configuration, the operator only comes with the parts contaminated with color and before the process ends with the parts which have already dried and are free of detergent in touch. There is no contact with the cleaning liquid. The vapors occurring during the course of the process are led out of the cleaning chamber, which is closed on all sides, before the cleaning chamber is opened to remove the cleaned parts. The consumption of cleaning agents can be reduced to the required minimum by the automatic procedure. Filters and containers for new or used cleaning agents can be exchanged easily.

An expedient embodiment of the method for cleaning spray guns with a handle and a trigger bracket of the trigger mechanism arranged in the handle area consists in that, before the spray gun is inserted into the cleaning chamber, the trigger bracket is fixed in the triggering position by a clip pushed over the trigger bracket and the handle becomes. It is then no longer necessary to disassemble the paint nozzle.

Yet another expedient embodiment is that the basket is driven by the jet emerging from the spray nozzles arranged laterally next to the basket. The drying air introduced into the cleaning chamber also keeps the basket rotating.

A device for cleaning objects, in particular for cleaning the exterior and interior of paint spray guns using a liquid cleaning agent, with a cleaning room, a container for new cleaning agent, a container for used cleaning agent, and a feed pump is used to carry out the method for the cleaning agent, a cleaning agent pressure line connected to the pump on the pressure side and in the area of the / 02667

Cleaning chamber arranged outlet and a return line leading from the cleaning chamber via a filter to the container for used cleaning agent are designed in such a way that the cleaning chamber is provided with an operating opening which can be closed airtight by a cover and a ventilation nozzle that in the cleaning chamber one by one vertical Axially rotatably mounted basket for receiving the objects to be cleaned is arranged, that the pump is assigned a compressed air motor as a drive, that the suction side of the pump is optionally connected via a three-way valve with the container for the new cleaning agent or the container for the used one Cleaning means can be connected so that the cleaning agent pressure line is distributed on the one hand with a branch line guided through the hollow axis of the basket and on the other hand below the basket and laterally next to the basket in a vertical direction over the height of the basket It is connected to the spray nozzles that at least one holder for a spray gun is arranged in the basket and that it is assigned a hose connection, starting from the two lines and provided with an adapter for connection to the paint access opening of the spray gun, and that a compressed air connection is provided to supply the pump drive ¬ can be seen.

An expedient embodiment consists in that the spray device at least of the spray nozzles arranged laterally next to the basket is aligned in the direction of rotation of the basket in such a way that the basket is acted upon by the pressure of the cleaning agent emerging from these spray nozzles, which acts on the basket and the objects to be cleaned Cleaner can be driven. A receptacle for small parts is preferably provided in the basket in order to be able to fix these in a position which is favorable for cleaning. According to a preferred embodiment, the receptacle has insertion openings for dyeing and air nozzles, in which the nozzles are arranged with approximately vertically extending nozzle channels, so that they can be sprayed through by the spray nozzles arranged below the basket .

Another advantageous embodiment consists in that the detergent pressure line is connected to a spray tube arranged under the basket and running approximately radially with respect to the basket and a vertical spray tube arranged laterally next to the basket, the spray tube facing the basket exhibit.

A further expedient embodiment consists in that the adapter for anchoring has spring tongues which can be inserted into the paint access openings of the spray gun.

According to a particularly expedient embodiment, the device is provided with a compressed air connection, which is connected via a first connection line provided with a first shut-off valve to the compressed air motor for the pump drive and via a second connection line provided with a second shut-off valve to a blow nozzle opening into the cleaning chamber is in the rest position, the shut-off valves are closed and an automatic, pneumatically operable control comprising three timing elements, which can be switched on by a start switch, is provided, the first timing element a pre-cleaning cycle, the second timing element a final cleaning cycle and the third timer is assigned to a drying cycle and the control is designed such that when the start switch is actuated the first shut-off valve is opened and the first timer is activated so that a first control sequence is initiated when the first timer expires which the three-way valve is switched from the connection to the container for used detergent corresponding to its rest position to the container for new detergent and the second timer is activated, and that when the second timer expires a second control sequence is initiated in which the first shut-off valve valve closed, the second shut-off valve opened, the three-way valve switched to its rest position and the third timer activated, after which the second shut-off valve is closed.

As a result of this configuration, not only the drive of the pump and the basket, but the entire, fully automatic program control is carried out purely pneumatically, with only the start button having to be pressed after the objects to be cleaned have been filled in and the lid closed.

A particularly expedient embodiment also consists in that a selection switch with two switch positions is provided, one of which is assigned to a full cleaning program, the three timing elements being activated in succession in the switch position assigned to the full cleaning program after the start switch has been pressed while in the switch position assigned to the rough cleaning program after the start switch has been pressed and the first timer has elapsed, bypassing the first control sequence, the second control sequence is initiated immediately. With this selection option, either a program with pre-cleaning, final cleaning and drying or a program with pre-cleaning and drying can be carried out, in which case the cleaning is carried out only by means of the filtered, used cleaning agent.

Yet another advantageous embodiment is that the second connection line has a branch which opens out into an injector arranged in the vent connection. As a result, the drying air mixed with cleaning agent vapor is sucked out by the action of an injector. The injector output should be adjusted so that the suction volume corresponds at least to the volume of the incoming drying air.

Preferably a part, i.e. at least one of the spray nozzles arranged below the basket is directed obliquely upwards against the direction of rotation of the basket. As a result, the back of the spray guns and their parts are molded on when the basket rotates.

Further advantageous or expedient refinements of the invention result from the subclaims in connection with the description.

The following description of an embodiment of the device according to the invention shown in the drawing will explain this in more detail.

It shows:

Fig. 1 is a schematic side view of a usual spray gun,

2 shows a schematic section through a cleaning device according to the invention, partly with an external view,

3 is a plan view of the device with the lid open,

4 shows a vertical section through the cleaning chamber of the device,

5 is a section through a small parts recording,

6 shows a plan view of the small parts receptacle according to FIGS. 6 and

7 shows a schematic circuit diagram of the device according to the invention.

The mode of operation and the use of the cleaning device according to the invention can be better understood if the basic structure of a paint spray gun, such as that shown in FIG. 1, is discussed first.

This spray gun, generally designated 10, consists of the actual gun body 12 with a handle 14, a connecting piece 16 for a paint cup 20 which can be closed by a cover 18, and an actuating mechanism, by which the trigger bracket 22 is pivotally mounted on the gun body 12 in the grip area . The paint comes out in the area of a nozzle head 24, into which a paint nozzle 25 is screwed and an air nozzle 26 is placed. A trigger needle 22 adjusts a nozzle needle 28 which changes the outlet cross section of the paint nozzle 25 in the axial direction.

For cleaning, the paint cup 20 is removed from the gun body 12, as are the air nozzle 26 and usually also the paint nozzle 25. In addition, the cover 18 is removed from the paint cup 20 so that the inside of the paint cup can be cleaned.

A paint conveying channel 29 extends from the connecting piece 16 to the nozzle head 24 in the interior of the gun body 12. In order that a cleaning liquid can be flushed through this paint conveying channel for cleaning purposes, the flow cross-section must be opened and for this purpose either the paint nozzle 25 must be removed or the release bracket 22 can be fixed in its release position. For this purpose, a clamp 30 can be pushed onto the handle 14 and the trigger bracket 22 pivoted against the handle 14 into its release position.

The device according to the invention has a cabinet-like housing 32 which accommodates in its lower region a small container 34 for new cleaning liquid and a larger container 36 for used, filtered cleaning liquid.

Arranged on an intermediate plate 38 above the containers 34 and 36 is a conveyor unit for the cleaning liquid, designated 40 as a whole, as well as a filter assembly 42, which serves to clean the used cleaning liquid in the manner explained below.

In the upper area of the housing 32 there is a cleaning chamber 44 with a ventilation nozzle 46 and a cover 48 which can be swiveled upwards and placed airtight, as well as a switching unit 50 for program control of the device. The entire device is operated by means of compressed air from a supply network, an air preparation device 52 being provided on the side in the lower region of the housing 32 for connection to the supply network.

A wire basket 56 is arranged in the cleaning chamber 44 so as to be rotatable about a vertical axis 54 and has an approximately frustoconical shape which widens upwards. The vertical axis 54 is hollow and is crossed by a branch line 58 for the cleaning liquid, which is connected at the upper end of the vertical axis 54 to, for example, two hose lines 60a and 60b, the meaning of which will be explained in more detail below.

The cleaning chamber 54 is laterally closed off by a cylindrical wall 62 in the example shown, which is arranged concentrically to the vertical axis 54.

A cleaning agent pressure line 64 opens into the cleaning chamber 44 and branches inside the cleaning chamber 44, specifically into a horizontal first spray tube 66 running below the wire basket 56 in a radial direction and a second one outside the wire basket 56 Second spray pipe 68 guided at the top, both spray pipes being provided with spray openings 67 and 69 directed against the wire basket 56. The spray openings 69 in the second spray tube 68 are directed onto the wire basket 56 in such a way that the loaded wire basket 56 is set in rotation by the emerging cleaning agent jets. In addition, the cleaning medium pressure line 64 is connected to the branch line 58. In the exemplary embodiment shown, the wire basket 56 is provided with two brackets 70a and 70b, each for a gun body 12. A connecting hose 60a or 60b is assigned to each holder 70a and 70b, an adapter 72a or 72b being provided at the end of the hose 60a or 60b, which adapter is intended to connect the hose 60a or 60b in the region of the connecting piece 16 to be connected to the paint inlet opening of the gun body 12. The design of the adapters 72a and 72b will be explained later with reference to FIGS. 5 and 6.

A drain line 74 is connected to the bottom of the cleaning chamber 44 and leads to the filter assembly 42, so that the cleaning agent injected into the cleaning chamber is cleaned in the filter assembly 42 and then fed to the container for the used cleaning fluid via a return line 76 .

The small container 34 for the new cleaning liquid is connected to a suction pipe 78, the large container 36 for the used cleaning liquid is connected to a suction pipe 80 be connected to a pump 84, on the pressure side of which the cleaning agent pressure line 64 is connected.

The pump 84 is actuated by a compressed air motor 86 which is connected to the air treatment device 52 via a compressed air line 88. In front of the compressed air motor 86, the compressed air line 88 first contains an oil supply device 90 in the conveying direction and then a shut-off valve 92. In front of the oil supply device 90 branches from the compressed air line 88 from a further compressed air line 94, which contains a second shut-off valve 96 and then divides into two line branches 95 and 99.

The switching device 52, as can be seen in FIG. 2, is provided with a start switch 100 and a selector switch 102, as well as with a control display 104, which shows whether the device is in operation.

A small, perforated container 106 is arranged inside the wire basket 56 and can hold small parts to be cleaned, for example paint cup lids 18, paint nozzles 25 and air nozzles 26. In addition, the wire basket 56 is provided with holders 108 for fixing the ink cups 20, which are inserted into the wire basket 56 in such a way that they are open towards the bottom.

Instead of the container 106, a disk-shaped receiving plate 107 (FIGS. 5 and 6) can also be inserted into the wire basket 56, which has two groups of insertion openings for the small parts of two spray guns in a mounting sector 109, namely insertion openings purple, 111b and 111c for paint nozzles 25 with different diameters and insertion openings 113 for the air nozzles 26. The free sector 115 can be used for inserting further parts.

An exhaust air line 110 connects to the compressed air motor 86 and ends at a silencer 117.

The switching device 50 finally comprises three pneumatic timers 114, 116 and 118, which can be set to a preselected time and according to time trigger a switching sequence pneumatically, as will be explained in more detail below.

The adapters 72a and 72b are each provided with at least one elastic tongue which can anchor the adapter in the paint nozzle mouth of the gun body 12.

In order to avoid that the sprayed cleaning agent can escape through the vent pipe 46, a sector-shaped discharge opening 132 is provided in the cylindrical wall 62, which is covered by a shielding plate 134, so that the cleaning agent vapors and the air only on the upper one and lower edge of the shielding plate can enter the trigger opening 132.

The cleaning process will now be explained in more detail with reference to the circuit diagram of FIG. 7, which is to be understood purely schematically. The pneumatic program control is shown in such a way that the chronological sequence of the two programs to be selected can be tracked. The pneumatic switching devices, in particular the pneumatic actuators for the shut-off valves 92 and 96 and the three-way valve 82 and the setting devices for the pneumatic timers 114 to 118 are not shown, however, because commercially available elements can be used.

After the objects to be cleaned have been brought into the cleaning chamber 44 and the cover 48 thereof has been closed, the desired cleaning program is first set on the selector switch 102. In the position of the selector switch 102 pointing to the left in FIG. 7, the full cleaning cleaning program switched on, which includes a rough cleaning by means of the already used cleaning agent in the container 36, a final cleaning by the new cleaning agent in the container 34 and a subsequent drying. If the selector switch 102 is placed to the right, only the rough cleaning with subsequent drying takes place.

In a simpler embodiment, the option can be dispensed with. The full cleaning program is then always carried out.

7 shows the two shut-off valves 92 and 96 and the three-way valve 82 in their basic position, which they each take after the program has run.

If the start switch 100 is actuated when the selector switch 102 is shown in FIG. 7, the shut-off valve 92 is opened and at the same time the timer 114 is activated. For the relatively long period of time set on the timing element 113, compressed air enriched with oil is now supplied to the compressed air motor 86 via the oil supply device 90, so that the pump 84 sucks in used cleaning agent via the suction pipe 80 and the three-way valve 82 and this into the cleaning agent pressure line 64 and from there to the corresponding consumption points, whereby the basket 56 is set in rotation and the cleaning process takes place within the cleaning chamber 44.

As soon as the timer 114 is expired, the timer 116 is activated via the control branch 136 branching off on the left in the selector 102 in FIG switched, in which the pump 84 sucks new cleaning liquid from the container 34 via the suction pipe 78 and conveys it into the cleaning agent pressure line 64 and to the consumption points.

This final cleaning phase will usually be shorter than the previous rough cleaning.

As soon as the timer 116 has expired, the shut-off valve 92 is moved back into its locking basic position. At the same time, the three-way valve 82 is reset to its basic position II. In addition, the shut-off valve 96 is opened, so that the pump 84 is now stopped and the compressed air is diverted upstream of the oil supply device 90 and introduced into line 94, from where it passes through line 95 as drying air to at least one blowing nozzle 97 Wall 62 is guided. At the same time, air is led via a line 99 to an injector 112, which is used to extract cleaning agent vapors and drying air from the cleaning chamber 44. After a period of time sufficient for drying, the timer 118 expires, as a result of which the shut-off valve 96 is moved back into its blocking basic position. The program has ended and the cleaned and dried objects can be removed from the cleaning chamber.

If the selector switch 102 was flipped to the right before the start switch 100 was actuated in FIG. 7, after the timer 114, which determines the duration of the coarse cleaning, has expired, the control branch 138 proceeding from the selector switch 102 on the right in FIG. 7 is activated, as a result of which the shut-off valve 92 is closed, the shut-off valve 96 is opened and the timer 118 is activated. In addition, the three-way valve 82 in Directed to its home position II. However, since it is already in this position, this control command has no further effect.

After the timer 188 has expired, the drying is ended and the shut-off valve 96 is closed.
