Description

The invention relates to a cleaning station for spray and / or rinsing of vehicle bodies with a wet medium, which has a turning device, which is a recording for includes a vehicle body and by means of which the vehicle body can be rotated into at least one cleaning position and at least one spray or flushing device includes.

The invention further relates to a Process for cleaning vehicle bodies by spraying and / or do the washing up the vehicle bodies with a wet medium in which a vehicle body by means of a rotating device in at least one cleaning position rotated and in this cleaning position with the wet medium sprayed and / or rinsed becomes.

Cleaning stations and cleaning methods of the type mentioned at the outset are known from the prior art ( DE 197 30 886 A1 ).

In particular, so-called "body washers" are made for cleaning the body shell of upcoming vehicle bodies before the pretreatment and Coating of the vehicle bodies in a coating system following the "body washer" known in which the vehicle body to be cleaned by one Angles of typically 15 to 20 ° tilted against the horizontal is sprayed from the outside in the tilted state by means of spray devices, tipped back into the horizontal starting position and then pulled out of the "body washer".

In these known cleaning stations the angle by which the vehicle body is tilted through the Construction of the "body washers "is limited the tilt angle by which the vehicle body is tilted specified. As a result, the vehicle bodies are often not in the cheapest Cleaning position for spraying and / or rinsing and draining the wet medium can be moved. This is especially true when the "body washer" is used to clean vehicle bodies different types because the cheapest for cleaning Tilt angle from the shape of the vehicle body to be cleaned depends in the well-known "body washer "the tilt angle but is fixed.

The invention is therefore the object to create a cleaning station of the type mentioned at the beginning, which enables To clean vehicle bodies of different types as efficiently as possible.

This task is done at a cleaning station with the features of the preamble of claim 1 according to the invention solved, that the rotating device is designed so that the Vehicle body recorded in the recording about an axis of rotation the rotating device from a starting position through an angle of rotatable more than 90 ° and in within the accessible Angular range of any predefinable cleaning positions can be stopped is.

With the cleaning station according to the invention can the vehicle body to be cleaned in one or more cleaning positions brought in which the body sprayed particularly effectively and / or rinsed be and the wet medium can run out of the body particularly quickly and completely. Since the Cleaning position or the cleaning positions within the accessible Angular range are arbitrary, it is possible to have different vehicle bodies - depending of the shape of the respective vehicle body type - one or to have several optimal cleaning positions.

In particular, it is in the cleaning station according to the invention possible, the cleaning position, in particular that for reaching the cleaning position required angle of rotation, depending on the type of to be cleaned Specify vehicle body so that each vehicle body, the is cleaned in the cleaning station, in each case for them optimal cleaning positions is brought, even when vehicle bodies different types pass through the same cleaning station in succession.

Because different areas of one Vehicle body different in a predetermined cleaning position sprayed effectively and / or rinsed can be is it convenient if the vehicle body into several by means of the rotating device different cleaning positions can be rotated. takes the vehicle body one after the other these different cleaning positions one so can those areas in each of these cleaning positions the vehicle body can be cleaned, which in the respective cleaning position particularly good for spraying and / or do the washing up accessible are.

Also eliminated by the possibility the vehicle body by means of one and the same rotating device to move into several different cleaning positions, the need for each of these cleaning positions a separate turning or tilting device provided. This allows the required total length of the Cleaning station can be kept small. The length of the rotating device of the Cleaning station only has to be a little bigger than the length a vehicle body.

In a preferred embodiment of the cleaning station according to the invention, that the cleaning station comprises at least one movable spray or rinsing device which, when the vehicle body is in the cleaning position, can be moved relative to the vehicle body into a working position assigned to the cleaning position of the vehicle body.

Such a movable spray or flushing can for a turning operation of the rotating device is moved into a rest position in which the spray or flushing device Completely outside the movement contours of the vehicle body and the turning device is arranged so that the Rotation of the vehicle body by the spray or flushing device in no way is hindered. For the cleaning process, the movable spray or rinsing device as close and in any orientation to the areas of the vehicle body to be cleaned be moved up.

The for the cleaning process of the spray or flushing device assumed working position is on the respective cleaning position matched the vehicle body; takes the vehicle body while of the cleaning process several cleaning positions, so can the spray or flushing device for every this cleaning positions of the vehicle body another working position be assigned. The type and number of cleaning positions the vehicle body and the cleaning positions assigned to them Working positions of the movable spray or rinsing device can adapted the shape of the vehicle bodies to be cleaned and thus for each Vehicle body type can be optimized.

To make difficult to access inner surfaces to be able to clean the cleaning vehicle body in a targeted manner it cheap if the cleaning station has at least one movable spray or rinsing device comprises which can be moved into the interior of the vehicle body.

Containing in cavities of vehicle bodies Contamination is a particular problem for cleaning preferred configuration of the cleaning station according to the invention is therefore provided that the Cleaning station comprises at least one movable flushing device, the in the working position assigned to the cleaning position on a entrance opening a cavity of the vehicle body is arranged. The one in question Cavity of the vehicle body can then by means of this flushing device targeted flushing and thus be effectively freed from contamination.

For the quality The cleaning result is primarily the amount used for rinsing of the wet medium and only secondly the pressure under which the wet medium is applied, significantly.

A high flow rate in a certain predetermined time can be achieved that the Vehicle body cavity being rinsed in the cleaning position is oriented substantially vertically. In this case, worry gravity for a quick one Flow away of the wet medium out of the cavity through outlet openings located at its lower end.

In order for the different too cleaning areas of the vehicle body each an optimal To achieve run-out behavior, it is beneficial if the vehicle body by means of the rotating device into several different from each other Cleaning positions is rotatable. Takes the vehicle body one by one these different cleaning positions, so in each of these cleaning positions each of those areas of the Vehicle body are cleaned, which in the relevant Cleaning position are particularly accessible and for which the vehicle body in the relevant cleaning position shows the best draining or draining behavior.

In addition, the possibility of the vehicle body by means of one and the same rotating device to move into several different cleaning positions, the need for each of these cleaning positions a separate turning or tilting device provided. This allows the required total length of the Cleaning station must be kept small. The length of the rotating device of the Cleaning station only has to be a little bigger than the length a vehicle body.

In order to ensure that the to achieve cleanable vehicle body, it is beneficial if the vehicle body by means of the rotating device substantially horizontal axis of rotation is rotatable.

In particular, it can be provided that the The axis of rotation does not cut the vehicle body, but below it or is arranged above the same.

Because the voids in the floor pan (especially in the sills) of the vehicle body, which is often particularly dirty are and their cleaning is therefore particularly important, essentially parallel to the longitudinal direction the vehicle body, it is favorable if the vehicle body by means of the rotating device about a transverse to the longitudinal direction of the vehicle body, preferably essentially perpendicular to the longitudinal direction of the vehicle body, aligned axis of rotation is rotatable. This makes it possible to mentioned above cavities in the floor pan of the vehicle body as strongly as possible against the horizontal tend to be a cheap one Leakage behavior when rinsing of these cavities to achieve.

Since the vehicle body can be rotated by an angle of more than 90 ° by means of the rotating device, the cavities in the floor assembly of the vehicle body can be substantially vertical aligned and thus an optimal run-out behavior can be achieved.

The rotating frame 152 is on two pedestals 158 around a perpendicular to the conveying direction 102 aligned horizontal axis of rotation 160 rotatably mounted. The pillow blocks 158 rest on the ground 124 which is also the cabin 114 wearing.

The drive of the rotating movement of the rotating frame 152 around the axis of rotation 160 takes place by means of an in 14 schematically illustrated rotary drive motor 162 which has a gearbox 164 those in the pedestals 158 mounted shaft 166 of the rotating frame 152 rotates.

The wave 166 is on both sides of the rotating frame 152 through the respective side wall 122 the cabin 114 passed through so that the side walls 122 the cabin 114 serve as covers through which the rotary drive motor 162 , The gear 164 and the pillow blocks 158 before cleaning vehicle bodies 108 used wet medium are protected.

Like from the 10 and 14 you can see the openings in the side walls 122 which of the wave 166 be penetrated by means of elastic seals 168 sealed.

On the top and bottom of the rotating frame 152 is one recording at a time 174a respectively. 174b for one on a skid frame 106 arranged vehicle body 108 intended.

The two shots 174a . 174b are the axis of rotation with respect to one 160 and the longitudinal direction of the rotating frame 152 containing plane formed mirror-symmetrical to each other, so that only the in 10 First shot shown above 174a will be described in detail.

How best to look 16 you can see the crossbeams 156 of the rotating frame 152 two longitudinal frame beams 170 with a Z-shaped profile, which is parallel to the conveying direction 102 extend and with respect to a longitudinal median plane 172 of the rotating frame 152 are symmetrical to each other.

The longitudinal frame beams 170 are at their front and rear ends by means of end plates 171 as well as between the end plates 171 arranged, transversely to the longitudinal direction of the longitudinal frame beams 170 one of the longitudinal frame beams 170 to the other longitudinal frame beam 170 extending cross struts 173 connected with a U-shaped or C-shaped cross-section.

On the longitudinal frame beams 170 are idlers spaced apart in the longitudinal direction thereof 176 to be perpendicular to the conveying direction 102 aligned horizontal axes of rotation 178 rotatably mounted.

The several, for example five, idlers 176 , which are equidistant along the conveying direction 102 are arranged together form a roller conveyor 180 the recording 174a the rotating device 110 ,

How out 16 can be seen includes each of the idlers 176 symmetrical to the median longitudinal plane 172 arranged cylindrical support body 182 , whose upper supporting body tips together form a supporting surface 184 for a skid frame 106 form.

The (in the conveying direction 102 seen) to the left of the median longitudinal plane 172 arranged support body 182 are with wheel flanges 186 for lateral guidance of the skid runners concerned 136 of a ski frame 106 Mistake.

Furthermore, each of the idlers carries 176 , adjacent to the respective trackless support body, two gears 188 , Via a gear wheel each 188 two adjacent idlers 176 is a chain 190 cocked so that the gears 188 and chains 190 together form a chain overdrive, through which the rotation of a support roller 176 on the adjacent idler 176 is transmitted.

One of the idlers 176 , for example the support roller lying furthest to the rear in the conveying direction 102 176a , is by means of a clutch 192 from an electric gear motor 194 an external roller conveyor drive part 193 set in rotation.

For this purpose, the wave 196 the idler 176a so that it extends over the (in the conveying direction 102 seen) right longitudinal frame beam 170 to the right side wall 122 the cabin 114 survives. This protruding part of the wave 196 is in one from the right cross member 154 of the rotating frame 152 worn prop 197 rotatably mounted.

How best from the 12 and 13 can be seen is on the free end of the wave 196 , which has a circular cross section, a driving pin with a square cross section 198 pushed on, which has a blind hole on one end 200 to accommodate the free end of the shaft 196 having.

The driving pin 198 is by means of a radial to the shaft 196 running threaded through hole of the driving pin 198 screwed threaded pin 202 rotatable on the shaft 196 established.

One of the wave 196 facing end of the driving bolt 198 is tapered and has a rounded tip 204 Mistake.

The driving pin 198 and the wave 196 form a first part of the coupling on the roller conveyor side 192 ,

A second part of the clutch on the drive part side 192 is non-rotatable with an output shaft 206 of the gear motor 194 connected.

How out 12 can be seen is on the output shaft 206 a cylindrical inner ring 208 with a stepped axial through hole 210 , its narrower, the geared motor 194 facing section 212 the output shaft 206 picks up, pushed on and by means of a support disc 212 and one the support disc 212 against the shoulder of the stepped through hole 210 pressing cylinder head screw 214 , which in an end axial threaded blind hole of the output shaft 206 is screwed in the axial direction relative to the drive shaft 206 fixed. A non-rotatable connection between the output shaft 206 and the inner ring 208 is by means of a feather key 216 manufactured, which in an axially aligned groove 218 on the circumference of the output shaft 206 and an adjacent axial groove on the inside of the narrow region of the stepped through hole 210 of the inner ring 208 intervenes. This (not shown) groove on the inner ring 208 extends in the axial direction of the inner ring 208 up to the gear motor 194 facing end face, so the inner ring 208 in the groove 218 the output shaft 206 key inserted 216 on the output shaft 206 can be postponed.

On the inner ring 208 is a receptacle 220 postponed, which one the geared motor 194 facing hollow cylindrical section 222 and the gear motor 194 facing, conically widening funnel section 224 includes.

A hollow cylindrical outer ring is in turn on the receiving bushing 220 226 pushed on, which has a thicker wall than the receptacle 220 having. The receptacle 220 and the outer ring 226 are by means of several screws 228 which have radial through holes in the outer ring 226 and in the receptacle 220 push through and into radial threaded blind holes in the inner ring 208 are screwed in, rotatably with the inner ring 208 connected.

Like from the 12 and 13 can be seen are also in the receptacle 220 , and that at the funnel section side end of the hollow cylindrical section 222 the receptacle 220 , two segment-shaped driver elements 230 is arranged, which by means of screws 232 , the radial through holes in the mounting bush 220 push through and into radial threaded blind holes in the driver elements 230 are screwed in, rotatably with the receptacle 220 are connected.

The mutually facing edges of the driver elements 230 are like out 13 can be seen, aligned parallel to each other and have such a distance from each other that the driver elements 230 the square section of the driving pin 198 can form-fit between them.

For easier insertion of the driving pin 198 between the driver elements 230 through into the hollow cylindrical section 222 the receptacle 220 the driver elements are inside 230 on their the output shaft 206 bevelled end faces.

How best to look 11 you can see the gear motor 194 on a sliding carriage 232 arranged, which - for example by means of rolling element recirculation guides 234 - on a sliding guide 236 parallel to the axis of the shaft 196 is slidably guided.

Around the sliding carriage 232 with the gear motor 194 along the sliding guide 236 moving is a movement device 238 provided which, for example, a pneumatic cylinder 240 with a piston that can be moved in it 242 comprises which by means of a coupling rod 244 on the sliding carriage 232 attacks so that the sliding carriage 232 in parallel to the direction of the axis of the shaft 196 is moved when the piston 242 from the pneumatic cylinder 240 is moved out or into it.

The gear motor 194 , the sliding carriage 232 who have favourited Shift Guide 236 and the moving device 238 for the sliding carriage 232 together form the external roller conveyor drive part 193 ,

For coupling the support roller 176a to the roller conveyor drive part 193 becomes the sliding carriage 232 with the gear motor arranged on it 194 in the radial direction on the one with the driving pin 198 provided end of the shaft 196 moved to the top 204 of the driving pin 198 through the funnel section 224 and the driver elements 230 through into the hollow cylindrical section 222 the receptacle 220 dips. Here come two of the side walls of the section of the driving bolt which is square in cross section 198 in engagement with the driver elements 230 , so that a rotationally fixed connection between the shaft 196 on the one hand and the output shaft 206 of the gear motor 194 on the other hand comes about.

After this rotationally fixed connection is established, the gear motor is actuated 194 the wave 196 the idler 176a (and thus, by means of the chain exaggerations, all idlers 176 the roller conveyor 180 ) rotated so that a skid frame 106 with the vehicle body arranged on it 108 from the feed roller conveyor 104 on the roller conveyor 180 the rotating device 110 drive in or from the roller conveyor 180 the rotating device 110 on the discharge roller conveyor 112 can extend.

To the rotating device 110 after such a transport operation again around the axis of rotation 160 Being able to turn is the sliding carriage 232 with the gear motor arranged on it 194 after switching off the geared motor 194 in the axial direction of the shaft 196 moved away from the same, so that the driving pin 198 out of engagement with the driver elements 230 comes and the connection between the shaft 196 and the output shaft 206 of the gear motor 196 is interrupted.

Like from the 10 and 11 can be seen, the rotary drive connection between the geared motor 194 and the driven idler 176a can only be manufactured if the roller conveyor 180 is in the starting position in which the support surface 184 the roller conveyor 180 is aligned horizontally and is at the same level as the support surfaces of the feed roller conveyor 104 and the discharge roller conveyor 112 , In the 10 and 11 this only applies to the roller conveyor shown above 180 the first shot 174a , but not on the roller conveyor shown below 180 the second shot 174b the rotating device 110 to.

As already mentioned, one is on the roller conveyor 180 opened skid frame 106 in terms of the rotating frame 152 against a relative movement parallel to the axes of rotation 178 the idlers 176 through the flanges 186 on the right-hand supporting bodies 182 secured.

A backup of the ski frame 106 against a relative movement relative to the rotating frame 152 in the longitudinal direction of the rotating frame 152 or perpendicular to the support surface 184 the roller conveyor 180 takes place by means of a locking device 244 , which is described below.

The locking device 244 includes one when the rotating frame rotates 152 with the same rotating locking part 246 and one when the rotating frame rotates 152 not rotating drive part 248 ,

The locking part 246 includes one parallel to the axes of rotation 178 the idlers 176 aligned threaded spindle 250 which on the longitudinal frame beams 170 and on one of the right cross member 154 worn prop 251 is rotatably mounted.

The threaded spindle 250 carries two threaded nuts 252 , which are guided laterally so that they rotate when the threaded spindle 250 do not turn, but, depending on the direction of rotation, move towards or away from each other.

A front thrust plate 254 and a rear push plate 256 are by means of push rods 258 so with the two threaded nuts 252 articulated that the four push rods 258 to form a diamond.

How best to look 17 you can see the front thrust plate 254 via a front push rod 260 articulated with a front bracket 262 and the rear thrust plate 256 via a rear push rod 264 articulated with a rear bracket 266 connected.

The two brackets 262 . 266 each include one rotatable on the brackets 170 the roller conveyor 180 held wave 268 , of which there is a short lever in the radial direction 270 away he stretches at which the front push rod 260 or the rear push rod 264 is articulated.

Each also includes brackets 262 . 266 two perpendicular to the conveying direction 102 spaced long levers 272 which is essentially perpendicular to the short lever 270 radially from the shaft 268 extend away and at their free end a cross-sectionally C-shaped bracket 274 wear.

In the in 17 shown closed position of the locking device 244 embrace the C-shaped temples 274 the brackets 262 . 266 one crossbar each 276 one on the roller conveyor 180 arranged ski frame 106 from above, from below and from behind or from the front, so that the skid frame 106 relative to the parentheses 262 . 266 in the longitudinal direction of the rotating frame 152 and perpendicular to the support surface 184 the roller conveyor 180 is set.

To the on the roller conveyor 180 fixed skid frame 106 to release the brackets 262 . 266 around the respective wave 268 from the relevant crossbeam 262 be swung away. How out 17 can be seen, it is necessary to do this, the push plates 254 and 256 to move away from each other. As further from the 15 or 16 you can see the threaded nuts 252 to be moved towards each other. One on the roller conveyor 180 arranged skid frame 106 can thus by means of the locking device 244 on the roller conveyor 180 locked or released by the threaded spindle 250 is rotated in a suitable direction.

To generate such a rotary movement, the one described above, with the rotating frame 152 rotating locking part 246 the locking device 244 with the in 14 External locking drive part shown 248 by means of a clutch 278 connected.

The first part of the coupling on the locking part side 278 is through the over the right longitudinal frame beam 170 laterally protruding part of the threaded spindle 250 and a drive pin arranged at its end 198 educated.

The one on the threaded spindle 250 arranged driving bolts 198 is designed in the same way as that already mentioned above in connection with the drive of the roller conveyor 180 driving bolts described 198 , so that reference is made to the above description.

The second part of the clutch on the drive part side 278 and the locking drive part 248 themselves are formed in the same way as the part of the clutch on the drive part side 192 and the idlers 176 the roller conveyor 180 driving roller conveyor drive part 193 , so that reference is also made to the above description.

It is thus possible in the same way, the gear motor 194 of the drive part 248 the locking device 244 by means of the clutch 278 with the locking part 246 the locking device 244 to put in operative connection when the roller conveyor 180 is in the starting position, as already mentioned above for the establishment of the connection between the geared motor 194 of the roller conveyor drive part 193 has been described.

How out 14 you can see the drive parts 193 . 248 , especially the geared motors 194 outside the cabin 114 arranged and penetrate the receptacles 220 Through openings in the side walls 122 the cabin 114 so that the side wall in question 122 serves as a cover through which the roller conveyor drive part 193 and the locking drive part 248 before cleaning vehicle bodies 108 used wet medium are protected.

Like from the 10 and 14 can be seen are in the lower area of the rotating device 110 , ie below the axis of rotation 160 , stationary spray lances 148a and mobile spray lances 150a and in the upper part of the rotating device 110 , ie above the axis of rotation 160 , stationary spray lances 148b and mobile spray lances 150b on the side walls 122 the cabin 114 arranged. The openings in the side walls penetrated by the spray lances 122 are by means of elastic seals 277 sealed.

The mobile spray lances 150a . 150b are in horizontal direction from the path of the vehicle bodies by means of electromotive, hydraulic or pneumatic movement devices 108 retractable to the vehicle bodies 108 from the feed roller conveyor 104 on the roller conveyor in the starting position 180 the rotating device 110 or from the roller conveyor 180 the rotating device 110 on the discharge roller conveyor 112 to be able to promote.

Is a vehicle body 108 from the feed roller conveyor 104 on the roller conveyor 180 the rotator 110 promoted and by means of the locking device 244 attached to it are the mobile spray lances 150 movable into their vehicle body type-dependent working positions, in which the atomizer plates of these spray lances are the areas of the respective vehicle body to be sprayed 108 are immediately adjacent or the atomizer plates of the spray lances in the interior of the respective vehicle body 108 protrude to the inner surfaces of the vehicle body 108 abzusprühen.

Furthermore, in the area of the rotating device 110 on the ceiling wall 120 the cabin 114 movable surge nozzles 280 arranged, which by means of an electromotive, hydraulic or pneumatic movement device in the vertical direction to one on the rotating device 110 arranged vehicle body 108 are movable towards or away from the same.

Each of the surge nozzles 280 includes a tube whose outside the cabin 114 arranged end is connected to a (not shown) wet medium supply and the other, in the cabin 114 arranged end tapers conically and is provided with an outlet opening (not closed by an atomizer plate) for the wet medium.

How best from the 1 to 9 can be seen is below the rotating device 110 a sump 282 arranged whose bottom 284 is so corrugated that several are transverse to the conveying direction 102 extending drain funnels 286 are formed, each of which has a drain opening at its lowest point 288 exhibit.

All drain opening 288 are connected to a wet medium discharge line 290 connected through which the in the sump 282 collected wet medium for further processing, such as cleaning or disposal, can be supplied.

On a front boundary wall 292 and on a rear boundary wall 294 the collecting tank 282 are two spray rings which are essentially U-shaped in the side view 296 held, which are connected to a (not shown) wet medium supply.

Like from the 4 to 10 you can see these thrower rings 296 Provided on their tops with spray nozzles through which wet medium onto the vehicle bodies to be cleaned 108 can be sprayed.

These spray nozzles can, for example, have the shape of short pipe sections which are attached to the spray rings 296 are fixed and through the side wall into the interior of the splash rings 296 lead.

To prevent spray lances or gushing nozzles 280 emerging and from one of the on the turning device 110 held vehicle bodies 108 dripping wet medium on the other vehicle body 108 arrives and dirty, is on both sides of the rotating frame 152 one partition each 279 provided which is parallel to the rotating frame 152 is aligned and both in the longitudinal direction of the in the recordings 174a . 174b recorded vehicle bodies and transversely to this longitudinal direction on the in the recordings 174a . 174b recorded vehicle bodies 108 survives.

Each of the partitions 279 is parallel to the longitudinal direction of the rotating frame 152 running troughs 281 provided which, for example, have a trapezoidal cross-section. Through these troughs 281 is on the respective partition 279 wet medium reaching in a defined manner to the front or to the rear end of the rotating frame 152 (depending on the current inclination of the rotating frame 152 ) directed from where the wet medium into the collection pan 181 drains without going to the one under the partition 279 arranged vehicle body 108 to get.

The first embodiment of a cleaning station described above 100 works as follows: In an in 4 shown operating state is a first vehicle body 300 on the discharge roller conveyor 112 and is there by means of the stationary spray lances 148 and movable spray lances 150 sprayed from the outside.

Will the cleaning station 100 used as a so-called "body washer" after the body shell and before entering a body coating system, it is used as a wet medium for cleaning the vehicle bodies 108 normal tap water with chemical cleaning additives, in particular degreasing additives, is used as the wet medium.

Will the cleaning station 100 used as a rinsing station within a body coating system after a pretreatment bath and before entering a dip painting basin, is used as a wet medium for cleaning the vehicle bodies 108 demineralized water (demineralized water) is used.

In both cases it becomes wet medium with opposite the ambient temperature increased Temperature of, for example, about 60 ° C is used.

Both in the area of the discharge roller conveyor 112 as well as in the area of the turning device 110 and the area of the feed roller conveyor 104 usually the same wet medium for cleaning the vehicle bodies 108 used; In principle, however, it is also possible to use different wet media in the three areas mentioned according to composition and / or temperature.

In the in 4 shown operating state is in (in 4 first shot shown below 174a the rotating device 110 a second vehicle body 302 recorded, which is in a lower cleaning position, in which the second vehicle body 302 by one An angle of 180 ° to the horizontal is rotated.

The second vehicle body is in this lower cleaning position 302 by means of the spray rings 296 sprayed from the outside in the area of the bonnet, roof and tailgate.

Also, in this lower cleaning position, how out 10 you can see the underbody of the vehicle body 302 and the interior of the same by means of in the lower region of the side walls 122 arranged movable spray lances 150a and the side parts of the second vehicle body 302 by means of in the lower area of the side walls 122 arranged stationary spray lances 148a sprayed.

Furthermore, in the 4 operating state shown a third vehicle body 304 in the in 4 Second shot shown above 174b the rotating device 110 recorded and is in a starting position in which the third vehicle body 304 has not yet been rotated with respect to the horizontal.

At the same time, this starting position is an upper cleaning position in which the third vehicle body 304 by means of in the upper area of the side walls 122 arranged movable spray lances 150b inside and outside and by means of the upper area of the side walls 122 arranged stationary spray lances 148b is sprayed outside.

That of the second vehicle body 302 Wet medium dripping in the lower cleaning position goes directly into the collecting pan 282 and flows out of the same through the wet medium discharge line 290 from.

The third vehicle body 304 Wet medium dripping in the upper cleaning position first enters the troughs 281 the partition 279 the second shot 174b flows in these troughs 281 to the front or rear end of the partition 279 and drips from there into the sump 282 without the second vehicle body in the lower cleaning position 302 to get there and pollute it.

Furthermore, in the 4 operating state shown a fourth vehicle body 306 on the feed roller conveyor 104 arranged and is lances there by means of the stationary spray 148 and the movable spray lances 150 sprayed from the outside.

After a cleaning cycle of the rotating device 110 is completed, the movable spray lances 150a and 150b in their rest positions, in which they are outside the path of the vehicle bodies 302 . 304 and the rotating frame 152 are located. Then the rotating frame 152 by means of the rotary drive motor 162 (in the direction of the 4 clockwise) by 90 ° around the horizontal axis of rotation 160 rotated until the in 5 shown operating state is reached. An intermediate state assumed by the rotating device during this rotation is shown in FIG 1 shown.

After completing the 90 ° rotation, the second vehicle body is located 302 in a second lateral cleaning position, in which this vehicle body is rotated by 270 ° with respect to the horizontal, and the third vehicle body 304 is in a first lateral cleaning position, in which this vehicle body is rotated 90 ° with respect to the horizontal.

After completing the rotary movement, the surge nozzles 280 so far down on the vehicle bodies 302 . 304 moved until the nozzle outlet openings are arranged near the inlet openings of cavities arranged in the floor groups of these bodies and are directed towards these inlet openings.

This is the working position of the surge nozzles 280 reached, the wet medium supply to the surge nozzles 280 opened, whereupon wet medium from the surge nozzles 280 under a pressure of 1 to 5 bar into the cavities in the floor panels of the vehicle bodies 302 . 304 penetrates, flows through this in a substantially straight line and exits again at the outlet openings of these cavities, which lie essentially vertically below the inlet openings, and into the collecting trough 282 arrives. By specifically flushing out the cavities in the floor panels of the vehicle bodies 302 . 304 a particularly good cleaning effect is achieved.

The floor assembly of the third vehicle body in the first lateral cleaning position 304 becomes from the back to the front and the floor assembly of the second vehicle body located in the second side cleaning position 302 is flushed from front to back.

The optimal working position of the surge nozzles 280 depends on the type of vehicle body to be cleaned 108 and is from a (not shown) control unit of the cleaning station 100 which the rotational movement of the rotating device 110 and the movements of the moving spray lances 150 and the surge nozzles 280 controls, depending on the type of vehicle bodies to be cleaned.

While the vehicle bodies 302 . 304 in the side cleaning positions, you can also use the spray rings 296 be sprayed from the outside.

After completing this cleaning cycle of the rotating device 110 become the surge nozzles 280 up from the path of the vehicle bodies 203 . 304 and the rotating frame 152 moved out. Then the rotating frame 152 by means of the rotary drive motor 162 (in the representation of the 5 seen) rotated clockwise through an angle of 90 ° until the in 6 shown operating state is reached, in which the second vehicle body 302 assumes the starting position, in which this body is not rotated with respect to the horizontal, and the third vehicle body 304 occupies the lower cleaning position, in which this body is turned 180 ° against the horizontal.

When the starting position is reached, the cleaning cycle for the second vehicle body is 302 in the rotating device 110 completed so that this body from the turning device 110 can be extended.

For this purpose, the control unit of the cleaning station 100 first the spraying process on the discharge roller conveyor 112 finished, and the moving spray lances 150 in the area of the discharge roller conveyor 112 become from the path of the first vehicle body 300 moved out.

Then the discharge roller conveyor is driven 112 actuated so that the first vehicle body 300 (in the representation of the 6 to the right) from the cleaning station 100 is conveyed into a subsequent pretreatment section or painting section.

Then the roller conveyor drive part 193 and the locking drive part 148 the locking device 244 in the manner described above by means of the couplings 192 respectively. 278 with the wave 196 the idler 176a or with the threaded spindle 250 connected. Then the gear motors are successively 194 of the locking drive part 148 and the roller conveyor drive part 193 actuated to first lock the ski frame 106 the second vehicle body 302 to solve and then the second vehicle body 302 by means of the roller conveyor 180 the first shot 174a the rotating device 110 on the discharge roller conveyor 112 to promote. This extending a vehicle body from the turning device 100 is in 3 shown.

Then the spraying process on the feed roller conveyor 104 interrupted, and the moving spray lances 150 in the area of the feed roller conveyor 104 become from the path of the fourth vehicle body 306 moved out.

Then the fourth vehicle body 306 by actuating the drive of the feed roller conveyor 104 on the roller conveyor 180 the first shot 174a the rotating device 110 conveyed and locked there by the direction of rotation of the geared motor 194 of the drive part 248 the locking device 244 is reversed.

A fifth vehicle body 308 (in the representation of the 6 seen from the left) from the in the conveying direction 102 in front of the cleaning station 100 lying area on the feed roller conveyor 104 promoted.

Then the movable spray lances 150 in the area of the feed roller conveyor 104, in the area of the discharge roller conveyor 112 and the moving spray lances 150b in the upper area of the rotating device 110 returned to their working positions to do the spray cleaning of the bodies 302 . 304 and 308 continue.

The drive parts 193 and 248 the roller conveyor 180 or the locking device 244 are made by moving the respective slide 232 from the wave 196 or from the threaded spindle 250 decoupled.

So that is in 7 shown operating state of the cleaning station 100 reached.

At the end of this work cycle of the turning device 110 become the moving spray lances 150a and 150b in the area of the turning device 110 in their rest positions, in which they are outside the movement contours of the vehicle bodies 304 and 306 and the rotating frame 152 are arranged.

Then the rotating frame 152 by means of the rotary drive motor 162 (in the representation of the 7 seen) clockwise by an angle of 90 ° around the horizontal axis of rotation 160 rotated until the in 8th shown operating state is reached, in which the third vehicle body 304 occupies the second lateral cleaning position, in which this body is rotated by 270 ° with respect to the horizontal, and the fourth vehicle body 306 occupies the first lateral cleaning position, in which this body is rotated by an angle of 90 ° to the horizontal.
