Description

The present invention relates to a cleaning station for Spraying and / or rinsing vehicle bodies with a Wet medium, which is a rotating device which has a receptacle for comprises a vehicle body and by means of which the driving Tool body rotatable in at least one cleaning position and comprises at least one spray or rinse device.

The present invention further relates to a method for Cleaning vehicle bodies by spraying and / or Rinsing the vehicle bodies with a wet medium, in which a vehicle body by means of a rotating device in min at least a cleaning position rotated and in this Reini sprayed with the wet medium and / or rinsed becomes.

Cleaning stations and cleaning methods of the beginning named type are known from the prior art.

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

In these known cleaning stations, the angle is around which the vehicle body is tilted by the construct tion of the "body washer" limited. In addition, the Kippwin angle around which the vehicle body is tilted give. As a result, the vehicle bodies are frequent not in the most favorable cleaning position for spraying and / or who rinses and drains the wet medium that can. This is especially true when the "body washer "for cleaning vehicle bodies Chen type is used because the cheapest for cleaning Tilt angle from the shape of the vehicle body to be cleaned series depends on the well-known "body washers" of the Kippwin kel is fixed.

The present invention is therefore based on the object to create a cleaning station of the type mentioned fen, which makes it possible to differentiate vehicle bodies type as efficiently as possible.

This task is carried out at a cleaning station with the Merk paint 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 by one turn axis of the rotating device from a starting position by one Angle of more than 90 ° rotatable and within the access angular range of any predefinable cleaning position gene is sustainable.  

With the cleaning station according to the invention, the can nending vehicle body in one or more cleaning positions are brought, in which the body in particular effectively sprayed and / or rinsed and the wet medium run out of the body particularly quickly and completely can. Because the cleaning position or the cleaning positions can be specified as required within the accessible angular range different vehicle bodies - depending on the shape of the vehicle body series types - one or more optimal cleaning positions to be taken.

In particular, it is in the cleaning station according to the invention tion possible, the cleaning position, in particular the When the cleaning position is reached, depending on the type of vehicle body to be cleaned to specify so that every vehicle body, which in the Reini cleaning station is cleaned in the best for you Cleaning positions are brought, even if vehicle checks series of different types successively the same Reini through the station.

Since different areas of a vehicle body in a given cleaning position differently effective can be sprayed and / or rinsed, it is beneficial if the vehicle body into several by means of the rotating device different cleaning positions can be rotated. The vehicle body takes these different one after the other Cleaning positions, so in each of these Reini positions of those areas of the vehicle box body cleaned in the respective Reini  position particularly good for spraying and / or rinsing are common.

In addition, there is no possibility of using one or the other same turning device the vehicle body into several of to move each other different cleaning positions that Need a se for each of these cleaning positions to provide a separate turning or tilting device. This can the required total length of the cleaning station is small will hold. The length of the rotating device of the cleaning station only has to be slightly larger than the length of a trip witness body.

In a preferred embodiment of the invention Cleaning station is provided that the cleaning station at least one movable spray or rinsing device summarizes which when driving in the cleaning position Tool body relative to the vehicle body in one of the Ar assigned to cleaning position of the vehicle body working position is movable.

Such a movable spray or rinsing device can be used for a turning operation of the turning device into a rest position be moved in which the spray or rinsing device completely outside the movement contours of the vehicle body and the rotating device is arranged so that the Rotation of the vehicle body through the spray or rinse direction is not hindered in any way. For cleaning operation can be the movable spray or rinsing device as close as possible and in any orientation to clean the areas of the vehicle body.  

The for the cleaning process from the spray or rinse The working position assumed depends on the respective Cleaning position of the vehicle body coordinated; takes the vehicle body several during the cleaning process Cleaning positions, so the spray or rinse direction for each of these cleaning positions of the vehicle body must be assigned to another working position. The Art and the number of cleaning positions of the vehicle body and the work assigned to these cleaning positions positions of the movable spray or rinsing device the shape of the vehicle body to be cleaned adapted and thus optimized for every vehicle body type become.

To difficult to access inner surfaces of a drive to be cleaned To be able to clean the tool body in a targeted manner, it is beneficial if the cleaning station has at least one movable spray or rinsing device, which in the interior of the driving Witness body is movable.

Contamina contained in cavities of vehicle bodies ions are a particular problem for cleaning. In a preferred embodiment of the invention Cleaning station is therefore provided that the cleaning station comprises at least one movable flushing device, the jobs assigned to the cleaning position tion at an entrance opening of a cavity of the vehicle ka body is arranged. The cavity in question the driving Tool body can then ge by means of this flushing device aims to be flushed out and thus effective from Kontamina cations are exempted.  

It is in for the quality of the cleaning result line shows the amount of wet medium used for rinsing and only in the second place the pressure under which the wet medium is applied, significantly.

A high flow rate in a given given Time can be achieved by driving the cavity Tool body that is rinsed in the cleaning position is oriented substantially vertically. In this case gravity ensures that the Naßme flows away quickly diums from the cavity through at its lower end che outlet openings.

In order for the different areas of the Vehicle body to optimal runout behavior achieve, it is favorable if the vehicle body by means of the rotating device in several different Rei tilt positions is rotatable. Takes the vehicle body one after the other these different cleaning positions, so can in each of these cleaning positions areas of the vehicle body are cleaned, which particularly accessible in the cleaning position concerned Lich and for which the vehicle body in the be appropriate cleaning position the best outlet or Ab shows dripping behavior.

In addition, there is no possibility of using one or the other same turning device the vehicle body into several of to move each other different cleaning positions that Need a se for each of these cleaning positions to provide a separate turning or tilting device. This can the required total length of the cleaning station is small  will hold. The length of the rotating device of the cleaning station only has to be slightly larger than the length of a trip witness body.

To ensure that the vehicle ka to be cleaned has a good run-out behavior To achieve the body, it is beneficial if the vehicle body series by means of the rotating device by an essentially ho horizontal axis of rotation is rotatable.

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

Since the voids in the floor pan (especially in the Sills) of the vehicle body, often particularly are heavily soiled and therefore their cleaning is particularly important what is important is essentially parallel to the longitudinal direction of the Vehicle body, it is favorable if the driving tool body by means of the turning device to a transverse to Longitudinal direction of the vehicle body, preferably essentially lichen perpendicular to the longitudinal direction of the vehicle body, aligned axis of rotation is rotatable. This makes it possible the aforementioned voids in the bottom group of the Vehicle body as strong as possible against the horizontal tend to have a favorable leakage behavior when rinsing this To create cavities.

Since the vehicle body by means of the rotating device the hollow can be rotated by an angle of more than 90 ° spaces in the floor assembly of the vehicle body essentially Chen vertically aligned and thus an optimal outlet behavior can be achieved.

In this case, the vehicle body in Reini be brought into positions in which the body around is rotated any angle to the horizontal. It is thus possible to fill the cavities in the vehicle body not just in one direction, for example from behind front, but in two directions, for example, too flush from front to back. Also with one every cleaning point can be rotated through a full 360 ° by rotating continuously in the same rotation direction reachable so that a smooth movement he is aimed and the times required for the turning ge short can be held.

It is particularly favorable if the rotary device of the Reini supply station is designed so that in the recording taken vehicle body around the axis of rotation of the rotation Direction freely rotatable and in any predetermined cleaning positions is sustainable. Since the vehicle body around the Free axis of rotation of the rotating device, that is, in any Angle of rotation, is rotatable and the cleaning positions, in de NEN the vehicle body to spray or rinse with  Wet medium is kept, can be predetermined, it is possible Lich, every vehicle body - depending on the Ge form of the respective vehicle body type - one or more more optimal cleaning positions. Ins In particular, it is possible to use the cleaning position, in particular re the necessary to reach the cleaning position Angle of rotation, depending on the type of driving to be cleaned to specify the vehicle body so that each vehicle body, which is cleaned in the cleaning station, in the for them optimal cleaning positions is brought, too if vehicle bodies of different types in succession go through the same cleaning station.

If it is advantageously provided that the Fahrzeugka body by means of the rotating device in two mutually opposite opposite directions of rotation is rotatable, this is ge ensures that regardless of the type and sequence of the cleaning positions of the vehicle body always the shortest turning path to transfer the vehicle body series from one cleaning position to the next Cleaning position can be used.

Carrying rollers 176, which are spaced apart from one another in the longitudinal direction of the longitudinal frame supports 170, are rotatable about horizontal axes of rotation 178 oriented perpendicular to the conveying direction 102 .

The plurality, for example five, support rollers 176 , which are arranged equi-distant along the conveying direction 102 , together form a roller conveyor 180 of the receptacle 174 a of the rotary device 110 .

As can be seen from Fig. 16, each of the support rollers 176 comprises symmetrical to the longitudinal center plane 172 arranged cylindrical support body 182 , the upper support body tips together form a support surface 184 for a skid frame 106 .

The (seen in the direction of conveyance 102 ) to the left of the longitudinal center plane 172 arranged support body 182 are provided with track rings 186 for lateral guidance of the skid runners 136 in question of a skid frame 106 .

Furthermore, each of the support rollers 176 , adjacent to the respective trackless rimless support body, carries two gear wheels 188 . Via a respective gear wheel 188 of two adjacent Tragrol len 176 are each a chain 190 taut, so that the gears 188 and chains 190 along a chain transfer drive to, by which the rotation of a carrying roller is transmitted to the respectively adjacent support roller 176 176 bil.

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

For this purpose, the shaft 196 of the support roller 176 a is elongated so that it projects over the (in the conveying direction 102 ) right longitudinal frame support 170 to the right side wall 122 of the cabin 114 . This protruding part of the shaft 196 is rotatably mounted in a support 197 carried by the right cross member 154 of the rotating frame 152 .

As can best be seen from FIGS. 12 and 13, on the free end of the shaft 196 , which has a circular cross-section, a cross-sectionally slid with mounting bolt 198 , which has a blind hole 200 on one end face for receiving the free end the shaft 196 has.

The driving pin 198 is fixed by means of a in a radially extending shaft 196 to the threaded through hole of the driving pin 198 is screwed the threaded pin 202 rotationally fixed to the shaft 196th

One end of the drive pin 198 facing away from the shaft 196 is tapered and provided with a rounded tip 204 .

The driving pin 198 and the shaft 196 form a roll-side first part of the coupling 192 .

A second part of the clutch 192 on the drive part side is connected in a rotationally fixed manner to an output shaft 206 of the geared motor 194 .

As can be seen from Fig. 12, slid onto and by means of a support plate 212 and one on the output shaft 206, a cylindrical inner ring 208 with a stepped axial through hole 210, the closer, the gear motor 194 to-facing section 212 receives the output shaft 206, the Support disc 212 against the shoulder of the stepped passage hole 210 pressing cylinder head screw 214 , which is screwed into a front axial threaded blind hole of the output shaft 206 , fixed in the axial direction relative to the drive shaft 206 . A rotationally fixed connection between the output shaft 206 and the inner ring 208 is made by means of a feather key 216 , 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 area of the stepped through hole 210 of the inner ring 208 engages. These (not shown) groove on the inner ring 208 extending in the axial direction of the inner ring 208 to which the gear motor 194 facing front face, so that may be the inner ring 208 in the groove 218 of the output shaft 206 inserted key member 216 positioned on the output shaft 206 inserted .

On the inner ring 208 , a receptacle 220 is pushed up ben, which comprises a gearbox 194 facing hollow cylindrical section 222 and a gearbox motor 194 facing away, conically expanding funnel section 224 .

On the receiving sleeve 220, in turn, a hollow cylindrical outer ring 226 is pushed, which has a thicker wall than the receiving socket 220th The receiving socket 220 and the outer ring 226 are prevail and by a plurality of screws 228, which radial through-holes acquisition socket in the outer ring 226 and in the 220-blind holes threads are screwed into the inner ring 208 in radial, rotationally fixed to the In nenring 208 is connected.

As can be seen from FIGS. 12 and 13, are further in the receiving sleeve 220 , namely at the funnel section side end of the hollow cylindrical portion 222 of the receiving sleeve 220 , two circular section-shaped driver elements 230 , which by means of screws 232 , the radial through holes in of the receptacle 220 and are screwed into radial threaded blind holes in the driver elements 230 , are non-rotatably connected to the receptacle 220 .

The mutually facing edges of the driver elements 230 are, as can be seen from Fig. 13, aligned parallel to each other and have such a distance from one another that the driver elements 230 can take the section of the driving bolt 198 with a quadratic cross-section between them.

To facilitate insertion of the driving pin 198 between the driver elements 230 through cut in the hollow cylindrical From 222 of the receiving sleeve 220 into the carriers are elements 230 on its output shaft 206 bevelled end faces facing away.

As can best be seen from FIG. 11, the gear motor 194 is arranged on a sliding carriage 232 , which - for example by means of rolling element circulation guides 234 - is displaceably guided on a sliding guide 236 parallel to the axis of the shaft 196 .

In order to move the sliding carriage 232 with the geared motor 194 along the sliding guide 236 , a loading device 238 is provided which comprises, for example, a pneumatic cylinder 240 with a piston 242 displaceable therein, which engages on the sliding carriage 232 by means of a coupling rod 244 , so that the sliding trimmed 232 is moved in parallel to the direction of the axis of the shaft 196 when the piston 242 is moved out of the pneumatic cylinder 240 or is moved into the same.

The gear motor 194 , the sliding carriage 232 , the sliding guide Ver 236 and the movement device 238 for the sliding carriage 232 together form the external roller drive part 193 .

To couple the idler roller 176 a to the roller conveyor drive part 193 , the sliding carriage 232 with the gear motor 194 arranged thereon in the radial direction is pushed to the end of the shaft 196 provided with the driving pin 198 until the tip 204 of the driving pin 198 is pushed through dips the funnel section 224 and the driver elements 230 into the hollow cylindrical section 222 of the receiving bushing 220 . In this case, two of the side walls of the cross-sectionally square section of the driving pin 198 come into engagement with the driving elements 230 , so that a torsional connection between the shaft 196 on the one hand and the drive shaft 206 from the geared motor 194 comes about on the other hand.

After establishing this rotationally fixed connection, the shaft 196 of the support roller 176 a (and thus, by means of the chain exaggerations, all the support rollers 176 of the roller conveyor 180 ) is rotated when the gear motor 194 is actuated, so that a skid frame 106 with vehicle body series 108 arranged thereon the feed roller conveyor 104 can move onto the roller conveyor 180 of the rotating device 110 or can extend from the roller conveyor 180 of the rotating device 110 onto the discharge roller conveyor 112 .

About the rotation device 110 according to such Transportvor gear again about the pivot axis to be able to turn 160, the slider carriage 232 is motor with thereon gear 194 after switching off the gear motor 194 in the axial direction of the shaft 196 is moved away from the same, so that the driving pin 198 except Engagement with the driver elements 230 comes and the connection between the shaft 196 and the output shaft 206 of the geared motor 196 is interrupted.

As the Drehan can in FIGS. 10 and 11 it can be seen drive connection between the drive motor 194 and is driven support roller are a only produced 176 when the roll sheet 180 is in the initial position in which the support surface 184 of 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 Figs. 10 and 11, this applies only to a shown above each roller conveyor 180 of the first receptacle 174, but not to the illustrated including roller conveyor 180 of the second receptacle 174 of the rotary device 110 b.

As already mentioned, a skid frame 106 mounted on the roller conveyor 180 is secured with respect to the rotating frame 152 against relative movement parallel to the axes of rotation 178 of the supporting rollers 176 by the wheel flanges 186 on the right-hand supporting bodies 182 .

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

The locking device 244 comprises a locking part 246 when the rotating frame 152 rotates with the same rotating Ver member and a non-rotating driving part 248 when the rotating frame 152 rotates.

The locking part 246 comprises a parallel to the axes of rotation 178 of the support rollers 176 aligned threaded spindle 250 which is rotatably mounted on the longitudinal frame members 170 and on a support 251 carried by the right cross member 154 .

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

A front pusher plate 254 and a rear pusher plate 256 are pivotally connected to the two threaded nuts 252 by means of pushrods 258 in such a way that the four pushrods 258 form a rhombus.

As best seen in FIG. 17, the front pusher plate 254 is articulated to a front bracket 262 via a front pushrod 260 and the rear pusher plate 256 is articulated to a rear bracket 266 via a rear pushrod 264 .

The two brackets 262 , 266 each comprise a shaft 268 rotatably held on the brackets 170 of the roller conveyor 180 , from which a short lever 270 extends in the radial direction, to which the front push rod 260 or the rear push rod 264 is articulated .

Furthermore, each of the clamps 262 , 266 comprises two long levers 272 spaced apart from one another perpendicular to the conveying direction 102 , which extend substantially perpendicularly to the short lever 270 radially away from the shaft 268 and at their free end in each case a bracket 274 with a C-shaped cross section wear.

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

In order to release the skid frame 106 defined on the roller conveyor 180 , the brackets 262 , 266 must be pivoted away about the respective shaft 268 from the respective crossbeam 262 . As can be seen from FIG. 17, it is necessary for that purpose, 254 and 256 to move the pusher plates away from each other. As can also be seen from FIGS. 15 or 16, this requires the threaded nuts 252 to be moved towards each other. A Skidrah men 106 arranged on the roller conveyor 180 can thus be locked or released by means of the locking device 244 on the roller conveyor 180 by rotating the threaded spindle 250 in a suitable direction.

To generate such a rotary movement, the locking part 246 of the locking device 244 described above, which rotates with the rotating frame 152 , is connected to the external locking drive part 248 shown in FIG. 14 by means of a coupling 278 .

The first part of the coupling 278 on the locking part side is formed by the part of the threaded spindle 250 projecting beyond the right longitudinal frame support 170 and a driving bolt 198 arranged at its end.

The arranged on the threaded spindle 250 drive pin 198 is formed in the same manner as the drive pin 198 already described above in connection with the drive of the roller conveyor 180 , so that reference is made to the above description.

The second part of the clutch 278 on the drive part side and the locking drive part 248 itself are designed in the same way as the part of the clutch 192 on the drive part side and the roller track drive part 193 driving the support rollers 176 of the roller conveyor 180 , so that in this respect likewise reference is made to the above description is taken.

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

As can be seen from FIG. 14, the driving parts 193, 248, in particular, the geared motors 194 outside the Ka bine 114 are disposed and extend through the receiving sockets 220 through openings in the side walls 122 of 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 are protected from the wet medium used for cleaning the vehicle bodies 108 .

As shown in FIGS. 10 and 14 can be seen, are in the lower region of the rotary device 110, that is, below the pivot axis 160, stationary spray lances 148 a and movable spray lances 150 a and in the upper region of the rotating device 110, ie above the axis of rotation 160 , stationary spray lances 148 b and movable spray lances 150 b arranged on the side walls 122 of the cabin 114 . The passage openings in the side walls 122 penetrated by the spray lances are sealed by means of elastic seals 277 .

The movable spray lances 150 a, 150 b are by means of electro motor, hydraulic or pneumatic Bewegungsein directions in the horizontal direction from the tap of the vehicle body 108 can be moved out to the vehicle bodies 108 from the feed roller conveyor 104 to the roller conveyor 180 in the initial position To be able to convey rotary device 110 or from roller conveyor 180 of rotary device 110 to discharge roller conveyor 112 .

If a vehicle body 108 is conveyed from the feed roller conveyor 104 onto the roller conveyor 180 of the rotating device 110 and fixed to it by means of the locking device 244 , the movable spray lances 150 can be moved into their vehicle body type-dependent working positions in which the atomizer plates of these spray lances are to be sprayed areas of the respective vehicle body 108 are immediately adjacent or the atomizer plates of the spray lances protrude into the interior of the respective vehicle body 108 in order to spray off the inner surfaces of the vehicle body 108 .

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

Each of the surge nozzles 280 includes a tube, the end of which is located outside the cabin 114 is connected to a wet medium supply (not shown) and the other end of which is located in the cabin 114 is tapered and has an end (not closed by an atomizer plate) is provided for the wet medium.

As can best be seen from FIGS. 1 to 9, a collecting trough 282 is arranged below half of the rotating device 110 , the bottom 284 of which is corrugated in such a way that several discharge funnels 286 extending transversely to the conveying direction 102 are formed, which are at their lowest point each have a drain opening 288 .

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

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

As can be seen from FIGS . 4 to 10, these spray rings 296 are provided on their upper sides with spray nozzles through which wet medium can be sprayed onto the vehicle bodies 108 to be cleaned.

These spray nozzles can for example, the form of short pipe pieces have, which are fixed to the rings 296 and spray rings through its side wall into the interior of the spray 296 open.

To prevent that from the spray lances or Schwalldü sen 280 escaping and passes from one of the vehicle bodies held on the turntable 110 108 dripping Naßmedium to the respective other vehicle body 108 and contaminates this, the rotation frame 152 is provided in each case a partition wall 279 on both sides , which is aligned parallel to the rotating frame 152 and protrudes both in the longitudinal direction of the vehicle bodies recorded in the receptacles 174 a, 174 b and also transversely to this longitudinal direction over the vehicle bodies 108 received in the receptacles 174 a, 174 b.

Each of the partitions 279 is provided with troughs 281 which run parallel to the longitudinal direction of the rotating frame 152 and which, for example, have a trapezoidal cross section. Through these troughs 281 , wet medium reaching the respective partition wall 279 is guided 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 ), from where the wet medium drips into the collecting trough 181 without of the vehicle body 108 arranged under the partition wall 279 .

The first embodiment of a cleaning station 100 described above works as follows:

In an operating state shown in FIG. 4, there is a first vehicle body 300 on the discharge roller track 112 and is sprayed there from the outside by means of the stationary spray lances 148 and movable spray lances 150 .

Is the cleaning station 100 used as a so-called "body-washer" in accordance with the body shell and prior to entering into a checks serie-coating system, it is as Naßmedium for cleaning of the vehicle bodies 108 as Naßmedium nor males tap water with chemical cleaning additives, in particular additives for degreasing, used.

Is the cleaning station 100 within a body-Be coating plant according to any pretreatment and prior to entry into a Tauchlackierbecken used as a rinsing station, so 108 demineralized water (deionized water) used as Naßmedium for cleaning of the vehicle bodies.

In both cases, wet medium is used with the opposite Exercise temperature of elevated temperature, for example used at 60 ° C.

Both in the area of the discharge roller conveyor 112 and in the loading area of the rotating device 110 and the area of the feed roller conveyor 104 , the same wet medium is usually used for cleaning the vehicle bodies 108 ; 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 operating state shown in FIG. 4, in the first receptacle 174 a (shown in FIG. 4 below) of the rotary device 110, a second vehicle body 302 is received, which is in a lower cleaning position in which the second vehicle body 302 is at an angle is rotated by 180 ° with respect to the horizontal.

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

In addition, in this lower cleaning position, as can be seen from Fig. 10, the underbody of the vehicle body 302 and the interior thereof by means of the movable Sprühlan zen 150 a arranged in the lower region of the side walls 122 and the side parts of the second vehicle body 302 by means of the sprayed lower region of the side walls 122 is arranged stationary spray lances 148 a.

Furthermore, in the operating state shown in FIG. 4, a third vehicle body 304 is shown in the second receptacle 174 b of the rotary device 110 shown in FIG. 4 above and is in a starting position in which the third vehicle body 304 is not yet opposite Horizontal has been rotated.

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

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

The wet medium dripping from the third vehicle body 304 in the upper cleaning position first enters the troughs 281 of the partition 279 of the second receptacle 174 b, flows in these troughs 281 to the front or rear end of the partition 279 and drips from there into the Sam Melwanne 282 without getting onto the second vehicle body 302 located in the lower cleaning position and soiling it.

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

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

After completion of the rotation by 90 °, the second vehicle body 302 is 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 ° from the horizontal.

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

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

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

The optimal working position of the surge nozzles 280 depends on the type of vehicle bodies 108 to be cleaned in each case and 34544 00070 552 001000280000000200012000285913443300040 0002019950197 00004 34425d is controlled by a control unit (not shown) of the cleaning station 100 which detects the rotary movement of the rotating device 110 and the movements 150 of the movable sprayer and the surge nozzle 280 controls depending on the type of vehicle bodies to be cleaned.

While the vehicle bodies 302 , 304 are in the side cleaning positions, they can also be sprayed from the outside by means of the spray rings 296 .

After completion of this cleaning cycle of the rotating device 110 , the surge nozzles 280 are moved upwards out of the path of the vehicle bodies 203 , 304 and the rotating frame 152 . Subsequently, the rotating frame 152 is rotated clockwise by an angle of 90 ° by means of the rotary drive motor 162 (seen in the illustration in FIG. 5) until the operating state shown in FIG. 6 is reached, in which the second vehicle body 302 the initial position occupies in which this body is not rotated relative to the horizontal, and the third vehicle body 304 occupies the lower cleaning position, in which this body is rotated 180 ° relative to the horizontal.

Upon reaching the starting position of the cleaning cycle is completed for the second vehicle body 302 in the turning device 110 so that this body direction from the Drehvor 110 can be extended.

For this purpose, the control unit of the cleaning station 100 ends the spraying process on the discharge roller conveyor 112 first , and the movable spray lances 150 in the region of the discharge roller conveyor 112 are moved out of the path of the first vehicle body series 300 .

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

Then the roller conveyor drive part 193 and the locking drive part 148 of the locking device 244 are connected in the manner described above by means of the couplings 192 and 278 to the shaft 196 of the support roller 176 a and to the threaded spindle 250 , respectively. Then the gear motors 194 of the locking drive part 148 and the roller conveyor drive part 193 are actuated one after the other in order to first release the locking of the skid frame 106 of the second vehicle body 302 and then the second vehicle body 302 by means of the roller conveyor 180 of the first receptacle 174 a to convey the rotating device 110 onto the discharge roller conveyor 112 . This extension of a vehicle body from the turning device 100 is shown in FIG. 3.

The spraying process on the feed roller conveyor 104 is then interrupted, and the movable spray lances 150 in the region of the feed roller conveyor 104 are moved out of the path of the fourth vehicle body 306 .

Subsequently, the fourth vehicle body 306 is promoted by actuating the drive of the feed roller conveyor 104 on the roller lenbahn 180 of the first receptacle 174 a of the rotating device 110 and locked there by the direction of rotation of the gear motor 194 of the drive part 248 of the locking device 244 is reversed .

In this position of the vehicle bodies 304 and 306 , in turn, the surge nozzles 280 are moved vertically downward into their working positions in order to flush through the cavities in the floor groups of the bodies 304 and 306 , as has already been explained above in connection with FIG. 5.

After completion of this cleaning cycle of the rotating device 110 , the surge nozzles 280 are moved back to their rest positions, in which they are arranged outside the path of the vehicle body lines 304 and 306 and the rotating frame 152 , and the rotating frame 152 is moved by means of the rotary drive motor 162 (in the viewing direction ) seen in FIG. 8 in the clockwise direction by an angle of 90 ° around the axis of rotation 160 until the in Fig. operating condition illustrated 9 is reached, in which the third vehicle body to the original state takes 304 in which this body does not face of Hori zontalen is rotated, and the fourth vehicle body 306 assumes the lower cleaning position, in which this body is rotated by an angle of 180 ° with respect to the horizontal.

Thus, the cleaning cycle for the third Fahrzeugkaros is serially completed in the turning device 110 304, and the third vehicle body 304 is extended 110, as has already been described above for the second vehicle body 302 device in the same manner from the rotation.

In the above description of the function of the first embodiment of the cleaning station 100 , it was assumed for the sake of simplification that the vehicle bodies in the rotating device 110 are brought into four different cleaning positions, in which the vehicle bodies are at angles of 0 °, 90 ° to the horizontal , 180 ° or 270 ° are rotated. Depending on the type of vehicle bodies to be cleaned, however, a smaller or a larger number of cleaning positions can also be provided, and the vehicle bodies can be rotated in this cleaning position by any other angle, for example by 0 °, 80 ° and 240 °, with respect to the horizontal his. Depending on the type of vehicle body to be cleaned, the control unit of the cleaning station selects the cleaning positions specified for this type of body and the associated working positions of the movable spray lances and the surge nozzles. The type of vehicle bodies to be cleaned is entered into the control unit either via a data line or by a suitable input device, or the cleaning station is provided with sensors, with the aid of which the control unit automatically recognizes the type of vehicle bodies to be cleaned.

The total wet medium throughput through the spray lances and surge nozzles of the cleaning station 100 is typically 100 to 1000 m ³ / h.

A second embodiment of the cleaning station 100 shown in FIGS. 18 to 23 differs from the first embodiment described above in that the vehicle bodies 108 from the rotating device 110 'of the second embodiment are not in the standard position, in which window openings of the vehicle bodies 108 above the are arranged in each floor assembly, but in a head overhang in which the window openings of the vehicle bodies 108 are arranged below the floor assembly.

In order to be able to extend the vehicle bodies 108 in the head overhang from the rotating device 110 ', each of the two receptacles 174 a, 174 b each not only comprises a roller track, but also a lower roller track 310 and an upper roller track 312 , the structure of which is described below becomes; the rotating device 110 'thus has a total of four roller tracks.

In the following, only the structure of the roller conveyors of the first receptacle 174 a (shown in FIGS. 21 and 22 above) will be described; the second receptacle 174 b is embodied mirror-symmetrically with respect to a plane containing the axis of rotation 160 and the longitudinal direction of the rotating frame 152 .
