Definitions
- the disclosure relates to a vehicle treatment system, in which at least one treatment device, in particular a washing portal, and a vehicle to be treated can be moved relative to one another within a treatment area, with a tactile collision detection device, which is supported on the treatment device via at least one connecting component and is in a starting position ( Zero position) located at an outer limit of the treatment area of the treatment device collision body and a sensor unit which is set up to detect a movement of the collision body relative to the treatment device as a risk of collision between the treatment device and the vehicle.
- a tactile collision detection device which is supported on the treatment device via at least one connecting component and is in a starting position ( Zero position) located at an outer limit of the treatment area of the treatment device collision body and a sensor unit which is set up to detect a movement of the collision body relative to the treatment device as a risk of collision between the treatment device and the vehicle.
- Vehicle treatment systems in particular gantry car wash systems, which are operated without training personnel, therefore generally have a device for monitoring the limits of the maximum treatment area. This device is intended to avoid a possible collision between the vehicle treatment system and the vehicle to be treated. Width monitoring is a device for monitoring the lateral limits of the vehicle treatment facility or the maximum passage width.
- Collision detection devices for vehicle treatment systems are known from the prior art, which use tactile systems or mechanical deflection systems, such as switching or contact strips, cable pull switches, flexible rods or the like, to avoid such damage. What all of these systems have in common is that when there is contact between the corresponding tactile switching element and the vehicle, a switching operation is carried out which forces the relative movement to stop.
- DE 10 2007 010 730 A1 shows a vehicle treatment system with a washing brush arranged transversely to the direction of movement of the system.
- the washing brush is arranged on a brush holder which is articulated pivotably on the system.
- a curved safety bar is provided on the brush holder, which causes the system to switch off immediately in the event of mechanical contact with the outer surface.
- DE 44 17 864 A1 shows a vehicle treatment system in which a treatment unit of the vehicle treatment system is moved along a side surface of a vehicle by means of a scanning device with at least one sensor designed as a light barrier.
- DE 10 2018 117 440 A1 discloses a vehicle treatment facility with a collision detection device in which optical sensors, in particular laser distance sensors, are provided for monitoring a lateral boundary of a treatment area of the vehicle treatment facility.
- Another example of non-contact sensors is shown in DE 20 2005 019418 U1. In this case, the vehicle treatment system has a scanning device for three-dimensional scanning and recording of a vehicle surface.
- optical measuring methods always have the disadvantage in the area of a vehicle treatment system that they are triggered incorrectly as a result of interference such as spray mist, water jets or other media. Accordingly, optical measuring methods have disadvantages that make reliable operation in the given measuring task difficult or impossible.
- the objects and goals of the disclosure are to eliminate or at least reduce the disadvantages of the prior art and in particular to provide a tactile vehicle treatment system which effectively and safely prevents a collision of the treatment device with the vehicle in all operating and/or movement states of the treatment device treated vehicle avoids.

- the collision body has such a large movement space both against and perpendicular to the direction of movement of the treatment device that it is ensured that the treatment device stops before the collision body strikes components of the treatment device and its movement is thus impeded. If the collision body is restricted in its movement before the treatment device has stopped, the treatment device may press the collision body against the vehicle, thereby damaging the vehicle.
- the collision body is supported on the treatment device via the at least one connecting component in such a way that, in the event of a collision with the vehicle, the collision body is displaced/retreats in a direction opposite to and/or in a direction perpendicular to the direction of movement of the treatment device, wherein a maximum displacement path/travel path that the collision body can describe in the collision with the vehicle due to the kinematics of its suspension is greater than a braking distance/overrun distance that the treatment device requires in order to stop after the sensor unit has detected a risk of collision.

- the figures are schematic in nature and are provided for understanding the disclosure only. Identical elements are provided with the same reference symbols. The features of the various embodiments are interchangeable.
- FIG. 1 is a perspective view of a vehicle treatment system (gantry car wash) 2 according to a first embodiment of the invention with a treatment device (gantry wash) 4 that can be moved relative to a vehicle to be treated (washed) in a relative direction of movement vr.
- the direction of movement vr is defined such that the treatment device 4 moves essentially along the longitudinal direction of the vehicle and sweeps the vehicle in the process.
- Such vehicle treatment systems 2 generally have a collision detection device 6 for monitoring the limits of the maximum treatment space B. This collision detection device 6 is intended to avoid a possible collision between the vehicle treatment system 2 and the vehicle to be treated.
- the maximum treatment space B in which no collision with a vehicle parked therein is to be expected, results from a projection of the washing brushes protruding from the inner edges or flanks of the treatment device 4, in particular for cleaning the vehicle wheels ( see Fig. 2) in the direction of relative movement vr.
- such a collision detection device 6 is implemented in the form of tactile width monitoring of the vehicle treatment system 2 .
- This is arranged on an outer boundary of the treatment room B and monitors in particular the lateral boundaries of the maximum treatment room B. It therefore ensures that a parked vehicle does not hit the inner edges or flanks of the portal columns of the treatment device 4 or treatment equipment protruding beyond them towards the middle of the treatment room. such as brushes and the like, collides.
- the collision detection device 6 detects that a section of a parked vehicle protrudes beyond the lateral limits of the maximum treatment space B and that there is a risk of a collision if the treatment device 4 or the vehicle moves further forward, it causes the relative movement between the treatment device 4 and the vehicle to stop by Treatment device 4 is stopped. In other words, the collision detection device 6 detects a risk of collision between the treatment device 4 and the vehicle by detecting a collision between the collision detection device 6 and the vehicle. If such a collision risk or collision is detected, the relative movement of the treatment device 4 is stopped.
- the collision detection device 6 is arranged upstream of the treatment device 4 in the relative movement direction vr. As shown in Fig. 1, the collision detection device 6 is attached to the treatment device 4 in such a way that there is a distance d between the collision detection device 6 and the treatment device 4 in a starting position (zero position) in which no vehicle collides with the collision detection device 6. This means that the collision detection device 6 is located in front of the treatment device 4 by the distance d in the relative movement direction vr. In the case of the vehicle treatment system 2 according to the disclosure, the distance d is greater than or equal to a stopping distance which the treatment device 4 describes after the collision detection device 6 has detected a risk of collision between the treatment device 4 and the vehicle.
- the collision detection device 6 has a collision body 8 which is designed as a collision bar 10 .
- the collision bar 10 as can be seen in FIG Treatment device 4, pendulously attached / suspended on the treatment device 4 and extends essentially parallel to a longitudinal strut / door 14 of the treatment device 4 downwards.
- the collision bar 10 is designed in two parts with a long bar segment 16 and a short bar segment 18 .
- the long rod segment 16 and the short rod segment 18 are arranged axially parallel to one another, are spaced apart from one another in the vertical direction of the vehicle treatment system 2 and are rigidly connected to one another via a coupling element 20 .
- the long segment rod 16 is arranged above the short segment rod 18 in the height direction of the vehicle treatment facility 2 .
- the short rod segment 18 is arranged axially parallel to the long rod segment 16 so as to protrude further toward the center of the treatment device 4 in a width direction.
- the long rod segment 16 can collide with an outside mirror of the vehicle, whereas the short rod segment 18 can collide with a body part in the floor area of the vehicle, such as a front apron, fender, etc.
- the collision detection device 6 makes it possible to use the short rod element 18 to detect a risk of collision between the treatment device 4 and the vehicle when the vehicle is placed with a lateral offset or at an angle in front of the treatment device 4 with respect to the relative movement direction vr.
- the collision detection device with the long rod segment 16 can detect a risk of collision between the treatment device 4 and the vehicle if the vehicle is placed so far laterally relative to the treatment device 4 that this would lead to a collision of the exterior mirror of the vehicle and the treatment device 4. An open door or a transverse position of the vehicle is detected using a combination of the long rod segment 16 and the short rod segment 18 .
- the collision bar 10 is supported against the door 14 of the treatment device 4 via an extruded profile (connecting component) 22 .
- the extruded profile 22 is rigid with the coupling element 20 with the Connected collision rod 10 and has a slot 24 which extends along a direction of extension of the extruded profile 22.
- the collision bar 10 is attached as a collision body 8 in front of the treatment device 4 .
- the collision bar 10 is suspended in an oscillating manner on the treatment device 4 and is supported against the treatment device 4 via the extruded profile 22 .
- the oscillating suspension and support via the extruded profile 22 enables a movement of the collision bar 10 relative to the treatment device, so that the extruded profile 22 and the collision bar 10 are moved away from the treatment space B or from the collision area.
- a pin 26 is formed on the treatment device 4, which is guided in the slot 24, so that the extruded profile 22 together with the collision bar 10 can move relative to the treatment device 4 counter to and transverse to the relative movement direction vr. That is, the extruded profile 22 and the collision bar 10 can move and rotate relative to the treatment device 4 . If the long rod segment 16 and/or the short rod segment 18 of the collision rod 10 collide with the vehicle, the collision rod 10 and the extruded profile 22 are displaced and/or twisted relative to the treatment device 4 .
- the collision detection device 6 in the above-mentioned starting position, in which no risk of a collision is detected or in which the collision bar 10 is not moved by the vehicle.
- the collision bar 10 is held in the initial position by a restoring element 28 .
- the restoring element 28 is designed as a flexible pulling device 30, which exerts a tensile or compressive force on the extruded profile 22 so that it is held in the starting position.
- a weight 32 is connected to the extruded profile 22 via a cable pull, so that the weight of the weight 32 presses the pin 26 against an end section of the slot 24 facing away from the collision bar 10 .
- the pulling device 30 is designed in such a way that the pulling force that holds the extruded profile 22 in the starting position has two directions of force, which together always pull the extruded profile 22 and thus the collision bar 10, regardless of the possible position in which they are located Drag towards the home position. This is realized in that the tensile force is directed via the movable weight 32 from a fixed position on the treatment device 4 to a position on the extruded profile 22 .
- Both positions are arranged in such a way that forces always act on the frame, which pull the extruded profile 22 into the starting position, against a stop (end section facing away from the collision bar 10) in the elongated hole 24 and against a stop (inner flank of the treatment device 4) on the treatment device ( see force components FR, V and FR of the restoring force FR in Fig. 5).
- the collision bar 10 now collides head-on with the vehicle, the collision bar 10 together with the extruded profile 22 moves back against the relative direction of movement vr until an end section of the slot 24 facing the collision bar 10 presses against the pin. If the extruded profile 22 is moved transversely to the relative direction of movement vr due to a lateral force component caused by an oblique collision of the collision body 10 with the vehicle, it pivots outwards until it finally presses against a rotary stop 34 on the treatment device 4 .
- a sensor 36 which can detect a change in distance is also provided in the collision detection device 6 according to the first embodiment, as shown in FIG. 5 .
- the sensor 36 is rigidly attached relative to or on the treatment device 4 and detects a change in distance to a sensor counterpart 38 that is rigidly attached to the end section of the extruded profile 22 facing away from the collision bar 10 .
- L By shifting the extruded profile 22 against the relative direction of movement vr along of the elongated hole 24 by L, in particular due to the collision bar 10 touching the vehicle, there is a displacement of the sensor counterpart 38 relative to the sensor 36 by L (see FIG. 6). This change in distance L is detected by sensor 36 .
- the vehicle treatment system 2 If the sensor 36 detects a change in distance L, L', the vehicle treatment system 2 is stopped and the treatment device 4 is stopped. Thus, the vehicle can be prevented from colliding with the treatment device 4 .
- the tensile force that holds the extruded profile 22 and the collision bar 10 in the initial position is transmitted as the weight of the weight 32 via the traction device 30 to the extruded profile 22 .
- 8 shows the collision detection device 6 according to a first modification of the first embodiment.
- a spring element 40 is provided for applying the tensile force to the extruded profile 22, which pulls the extruded profile 22 into the starting position via a cable pull.
- Figs. 9 and 10 show the collision detecting device 6 according to a second modification of the first embodiment.
- the collision bar 10 is supported on the treatment device 4 via two extruded profiles 22 spaced apart in the height direction of the vehicle treatment system 2, which is why the oscillating suspension of the collision bar 10 can be omitted.
- the extruded profiles 22 are each guided by the pin 26, which, as indicated in Fig. 10, extends through the elongated holes 24 of the two extruded profiles 22, so that the collision bar 10 together with the extruded profiles 22 can be displaced and/or twisted relative to the treatment device 4 in the event of a collision with the vehicle.
- the collision body 8 can be connected to the treatment device 4 via one, two or more connection components.
- the collision body 8 does not have to be held from above via the oscillating suspension.
- the collision body 8 is held on the treatment device 4 by a plurality of, preferably two, connecting components.
- the connecting components allow a movement of the collision body 8 relative to the treatment device 4.
- Two of the above-described extruded profiles 22 with slot 24 can be used as connecting components, which are held in their starting position by a force.
- the weight/tractive force of the collision body 8 and the connecting components is applied via a stop which is attached under one of the two connecting components.
- the collision body 8 Due to the elongated hole kinematics of the two connecting components, the collision body 8 can be tilted forwards and backwards and can be rotated about the pivot point of the pin 26. The two connecting components are pulled into the starting position by the tensile forces described above.
- the figs. 11 and 12 shows a collision detection device 6 according to a second embodiment.
- the collision rod 10, i.e. the long rod segment 16 and the short rod segment 18, is supported on the treatment device 4 via a fixing element (connecting component) 42 that is flexible in shape.
- the fixing element 42 is at least partially made of an elastomer or of elastic or resilient segments and can therefore deform reversibly, i.e. after a deformation, for example as a result of a collision of the collision bar 10 with the vehicle, the fixing element 42 reverses automatically returns to the starting position due to its own elasticity.
- the fixing element 42 which can contain parts made of elastomer or spring elements, thus enables a free overtravel in several directions.
- the fixing element 42 is attached to the treatment device 4 with an end section facing away from the collision bar 10 .
- a sensor arrangement 46 is arranged on fixing element 42 .
- the sensor arrangement 46 has a cup-shaped sleeve 48 which is screwed to the mount 44 .
- a rod end piece 50 which is coaxially coupled to the long rod segment 16 in a stationary manner, at least in an axial direction, extends in the height direction of the vehicle treatment system 2 from above into the interior of the sleeve 48.
- On an inner peripheral surface of the Sleeve 48 is a centering assembly 52 which centers the rod end 50 and sleeve 48 to each other. That is, centering arrangement 52 enables concentric positioning of rod end piece 50 and sleeve 48.
- centner arrangement 52 As shown in FIG.
- the torsion springs 56 bear against the inner peripheral surface of the sleeve 48 and an outer peripheral surface of the rod end piece 50 in order to keep the sleeve 48 and the rod end piece 50 concentric with one another.
- a sensor 58 is fastened to the sleeve 48 in such a way that it extends downward from a bottom plate 60 of the sleeve 48, preferably perpendicularly.
- the sensor 58 is set up to detect an offset of a sensor counterpart 62 lying opposite it, in particular in the height direction.
- the sensor counterpart 62 is accommodated in the rod end piece 50 in an axially displaceable manner in order to be able to compensate for longitudinal displacements of the long rod element 16 .
- a lever mechanism 64 is provided on the coupling element 20, which rigidly connects the long rod element 16 and the short rod element 18 to one another arranged. As seen in FIG.
- the lever mechanism 64 is diametrically opposed to the short rod member 18 with respect to the sleeve 48.
- a punch 68 is accommodated, which can hit an outer peripheral surface of the sleeve 48 in a collision between the short rod segment 18 and the vehicle, so as to prevent relative tilting between the rod end piece 50 and the sleeve 48 and thus to cause a detectable offset between the sensor 58 and the sensor counterpart 62.
- the collision detection device 6 thus enables a collision between the collision bar 10 and the vehicle to be detected at an interface between the collision bar 10 and the fixing element 42 by detecting a position shift of the collision bar 10 within the interface. If the collision bar 10 is further displaced during the collision with the vehicle, the collision bar 10 together with the sensor arrangement 46 can move outwards due to the flexibility of the fixing element 42 .
- the lower end of the long rod segment 16 is centered in the cup-shaped sleeve (cup) 48 fixed to the fixing member 42 .
- the sensor 58 is located under the rod end piece 50 and registers the offset of the sensor counterpart 62 lying opposite it.
- This sensor counterpart 62 is mounted in a bore of the rod end piece 50 in such a way that longitudinal displacements of the long rod segment 16 are compensated.
- the rod end piece 50 is touched by the torsion springs 56 over the circumference, with the result that it is always aligned centrally in the sleeve 48 .
- Displacement of the long rod segment 16 causes the rod end 50 is pressed against the torsion springs 56 in such a way that it leaves the central position and can touch a stop in the sleeve 48. This movement is detected by the sensor 58.
- the long rod segment 16 is displaced by the vehicle in a collision with the vehicle, causing the rod end 50 to deform the torsion springs 56 until it contacts the stop in the sleeve 48 . Further displacement of the long rod segment 16 by the vehicle results in the locating member 42 allowing the crash bar 10 and sleeve 48 to move.
- the short rod segment 18 is rigidly connected to the long rod segment 16 .
- the lever mechanism 64 ensures that any contact transmitted from the vehicle to the short rod segment 18 results in displacement of the rod end piece 50 within the sleeve 48 .
- the Figs. 14 and 15 show a collision detection device 6 according to a third embodiment.
- the collision bar 10 is supported on the treatment apparatus 4 via a support member (connecting component) 70 .
- the support element 70 can be made completely or partially from an elastomer, so that the support element 70 can deform reversibly and thus provides a restoring force due to its own elasticity, which pushes the support element 70 and the collision bar 10 into the starting position.
- An end portion of the long rod member 16 located in the height direction of the vehicle treatment facility 2 is fixedly connected to an end portion of the support member 70 .
- the short rod element 18 is also rigidly connected to the long rod element 16 via the coupling element 20 .
- the support element 70 is connected at its end section facing away from the collision bar 10 to a first L-shaped angle profile 72 which is guided in a second L-shaped angle profile 74 arranged stationary on the treatment device 4 .
- the long leg of the second angle profile 74 is attached to the treatment device 4 and has a pin 76 in the end area of its short leg, which extends through a slot 78 formed in the end area of the short leg of the first angle profile 72 . If the collision bar 10 comes into contact with the vehicle, the collision bar 10 can move back against the relative direction of movement vr due to the elongated hole 78 .
- the first angle profile 72 can rotate relative to the second angle profile 74 about the pin 76 as the pivot point.
- This twisting movement is limited on the one hand by the long leg of the second angle profile 74, ie by the inner edge of the treatment device 4, and on the other hand by a stop 80 formed in the end region of the long leg of the second angle profile 74.
- the flexible support member 70 thereby allows outward movement/retreat in the width direction of the vehicle treatment facility 2 .
- a sensor 82 in particular a compressive force movement sensor, is arranged on a region of the short leg of the second angle profile 74 opposite the pin 76.
- a stamp 84 is accommodated in the first angle profile 72 opposite the sensor 82 . If the collision bar 10 collides with the vehicle, this collision force is transmitted to the first angle profile 72 . The plunger 84 presses against the sensor 82 so that the sensor 82 can detect this collision force and thus also the collision between the collision bar 10 and the vehicle.
- the collision detection device 6 enables detection of a collision between the collision bar 10 and the vehicle at an interface between the treatment device 4 and the support member 70.
- the collision detection device 6 is constructed in such a way that a movement of the collision bar 10 leads to a force between the collision bar 10 and the support element 70 .
- the support element 70 is supported on the treatment device 4 .
- the forces acting on the collision bar 10 in acting in two directions of force, are converted so that they can be detected with the sensor 82, which only measures in one direction of force.
- the support element 70 is rigidly connected to the first angle profile 72 in order to be able to transmit all forces to it.
- the pin 76 , the stop 80 and the sensor 82 are rigidly connected to the second angle profile 74 , which in turn is fastened in a stationary manner to the treatment device 4 .
- the first angle profile 72 is supported via the elongated hole 78 on the pin 76 and is supported via the stop 80, against which the first angle profile 72 is supported on the second angle profile 74, so that all collision forces are transmitted via the plunger 84 to the sensor 82 become.
- Collision forces on the collision bar 10 transversely to the relative movement direction vr result in a moment on the first angle profile 72.
- the counter-moment is generated by a force on the pin 76 and a force on the sensor 82. This force on the sensor 82 is detected to detect the collision between the crash bar 10 and the vehicle.
- Collision forces on the collision bar 10 against the relative direction of movement vr are passed directly to the sensor 82 via the first angle profile 72 and the stamp 84 in order to detect the collision between the collision bar 10 and the vehicle.
- FIGS. 16 and 17 show a collision detection device 6 according to a fourth specific embodiment.
- the long rod segment 16 and the short rod segment 18 are rigidly connected to one another via the coupling element 20 .
- the collision bar 10 is supported to the treatment apparatus 4 via a support member (connecting member) 86 .
- the support element 86 can be made completely or partially from an elastomer, so that the support element 86 can deform reversibly and thus provides a restoring force due to its own elasticity, which pushes the support element 86 and the collision bar 10 into the starting position.
- a sleeve-shaped receptacle 88 is formed on the support element 86 on an end section facing away from the treatment device 4, into which a lower End portion of the long rod segment 16 engages.
- at least one sensor 90 is arranged between an inner peripheral surface of the receptacle 88 and an outer peripheral surface of the long rod segment 16 .
- the at least one sensor 90 is set up to detect a contact force which acts between the long rod segment 16 and the support element 86 when the collision rod 10 collides with the vehicle.
- Such sensors 90 can be, for example, strain gauges or piezoelectric sensors.
- the collision forces are transmitted to the receptacle 88 via the long bar segment 16 .
- the at least one sensor 90 mentioned above is arranged at the interface between the long rod segment 16 and the receptacle 88 in order to be able to detect the transmitted forces and thus to detect a collision between the collision rod 10 and the vehicle.
- the collision detection device 6 enables a collision between the collision bar 10 and the vehicle to be detected by detecting a force in the interface between the collision bar 10 and the support element 86 via the corresponding sensor 90 .
- FIG. 18 shows a collision detection device 6 according to a fifth specific embodiment.
- the collision bar 10 is supported on the door 14 of the treatment device 4 via a spring-bar arrangement (connecting component) 92 .
- the spring-rod arrangement 92 has a plurality of rigid rods 94, rods or plates, which are each coupled to one another via a spring 96.
- the spring-bar arrangement 92 enables the movement of the collision bar 10 to detect a collision with the vehicle and at the same time provides the restoring force due to the spring force of the springs 96 in order to press the collision bar 10 into the starting position.
- sensors can be provided in the interface between the spring-rod arrangement 92 and the door 14 and/or in the interface between the spring-rod arrangement 92 and the collision bar 10 .
- a sensor can also be arranged in the area of the springs 96 or rods 94 , ie within the spring-rod arrangement 92 .
