Description

Technical Field

[0001] This invention relates to a safety device for contact detection of obstacles, particularly vehicles, in vehicle handling facilities, especially vehicle washing facilities. The safety device includes a holding device fixed or capable of being fixed to a support of the vehicle handling facility for movably securing the safety device to the support; an impact device held by the holding device and capable of deflecting from a non-operational position to at least one operational position due to contact with an obstacle; a sensor device operatively connected to the impact device and capable of detecting at least the impact device occupying a non-operational position and / or an operational position; and a reset device connected to the impact device and connected or capable of being connected to the vehicle handling facility to transfer the impact device to a non-operational position without contact with the vehicle.

[0002] Furthermore, the present invention also relates to a vehicle treatment facility for treating vehicles, particularly washing and / or polishing. The vehicle treatment facility includes safety equipment of the type described above and a support device, particularly a support column, for supporting at least one vehicle treatment unit, wherein the safety equipment is mounted on the support device facing the vehicle treatment area, particularly the vehicle washing area. The safety equipment ensures the safety of the support device, for example, in the direction towards the vehicle treatment area. Background Technology

[0003] For example, in a vehicle handling facility of the type described at the beginning, safety devices of that type are used to ensure that, when, for example, the carrying device moves toward an obstacle, the obstacle does not collide with the carrying device or with the vehicle handling unit arranged on the carrying device. The obstacle is particularly a vehicle, but it can also be a person or other obstacle. By designing the impact device to be deflectable and capable of detecting obstruction, damage, particularly to vehicles, people, or the vehicle handling facility, can preferably be avoided.

[0004] It is worth anticipating that the system can reliably distinguish between occupying a non-operational position and / or occupying an operational position that deviates from the non-operational position. Summary of the Invention

[0005] The objective of this invention is to provide a safety device that can reliably distinguish between occupying a non-operational position and / or occupying an operational position that deviates from the non-operational position.

[0006] This task is solved by a safety device according to the invention, which is used for contact detection of obstacles, especially vehicles, in vehicle handling facilities, particularly vehicle washing facilities. The safety device includes a holding device that is fixed or can be fixed to the vehicle handling facility for movably securing the safety device to a carrier; an impact device that is held by the holding device and can be deflected from a non-operational position to at least one operational position due to contact with an obstacle; a sensor device that is operatively connected to the impact device and can detect at least the impact device occupying a non-operational position and / or an operational position; and a reset device that is connected to the impact device and connected or can be connected to the vehicle handling facility, such as its carrier, to transfer the impact device to a non-operational position without contact with the vehicle. The connection between the reset device and the impact device enables the transmission of torque between the reset device and the impact device, and / or the connection between the reset device and the vehicle handling facility enables the transmission of torque between the reset device and the vehicle handling facility.

[0007] By transmitting torque between the reset device and the impact device and / or between the reset device and the vehicle handling facility, the reset device is preferably relatively rigidly connected to the impact device on one side and / or to the vehicle handling facility on the other. This allows the impact device to be reliably transferred to a non-operational position and thus reset, and preferably held in the non-operational position against deviation. This is advantageous, for example, for avoiding unintentional deviation caused, for example, by a moving vehicle handling facility.

[0008] Preferably, the design scheme according to the invention can save at least one additional reset element and / or retaining element for the impact device, thereby giving the safety device a design scheme with a simple design structure.

[0009] As a comparative example, suppose a tension spring is used to reset the impact device. This tension spring, especially when the deviation is large, can cause relatively persistent vibrations around the non-operational position. When the deviation is small, only a small reset force may be applied, which may delay reset. In contrast, a coupling established for transmitting torque will preferably reset the impact device to the non-operational position more accurately, reliably, and / or quickly, and preferably hold it in the non-operational position more reliably.

[0010] Currently, "connection" can be understood, for example, as the connection between a reset device and an impact device and / or a load-bearing device of a vehicle handling facility.

[0011] Currently, occupying a non-manipulating position can be understood, in particular, as occupation in the sense of moving from a manipulating position to a non-manipulating position and / or remaining in a non-manipulating position. Currently, occupying a manipulating position can be understood, in particular, as occupation in the sense of moving from a non-manipulating position to a manipulating position and / or remaining in one or more manipulating positions.

[0012] Starting from a non-operational position, contact with an obstacle can cause the impact device to deviate, particularly in at least one direction, into at least one operational position. Advantageously, it can deviate into multiple operational positions, wherein the deviance of the impact device depends on where it contacts the obstacle. For example, the deviance can occur in the longitudinal direction of the vehicle handling facility (especially relative to the direction of entry) and / or in the lateral direction, preferably in both directions. Advantageously, there is a possibility of deviance occurring in a direction derived by superimposing the longitudinal and lateral directions. Therefore, the deviance can preferably occur at any angle to the direction of entry and can occur in the direction of entry itself. As a result, safety devices have proven to be particularly diverse, and the vehicle handling facility has a high degree of operational safety.

[0013] Sensor devices designed to detect the transition between non-operated and operated positions can have relatively fast response characteristics.

[0014] Sensor devices designed to detect whether a position is in a non-operational or operational position can be particularly insensitive to interference.

[0015] The connection between the reset device and the impact device and / or the vehicle handling facility is designed, for example, to transmit bending torque, especially cutting torque relating to bending and / or twisting of the reset device.

[0016] Preferably, not only the connection between the reset device and the impact device, but also the connection between the reset device and the vehicle handling facility are configured to transmit torque.

[0017] The connection between the reset device and the impact device, and / or the connection between the reset device and the vehicle washing facility, may, for example, have a gap. A gapped connection can, for example, prevent the reset device from being pre-tightened.

[0018] The connection between the reset device and the impact device, and / or the connection between the reset device and the vehicle washing facility, can be, for example, gapless. A gapless connection allows for more precise reset, for example.

[0019] Preferably, the reset device is supported on the impact device and / or vehicle handling facility by means of at least a 5-weltig bearing. The 5-weltig bearing, for example, enables a particularly robust connection of the reset device.

[0020] For example, the reset device is supported on the impact device and / or vehicle handling facility by means of a hexavalent (6-wertig) bearing. The hexavalent bearing, for example, enables unambiguous connection of the reset device.

[0021] The retaining device can be fixed or can be fixed to the supporting device of the vehicle handling facility. The fixation can be rigid or movable.

[0022] Preferably, the retaining device is designed to elastically hold the impact device on the carrier. For example, this can cause the impact device to make movements (e.g., in the case of slight deviation) limited only by the reset device. Thus, it is preferable to prevent the impact device from oscillating, for example, to avoid damage to the paint of the vehicle that comes into contact with the impact device.

[0023] If the reset device is connected to the impact device at one end and to, or can be connected to, a vehicle handling facility at the other end, the impact device can be deflected far away upon contact. For example, this can prevent damage to the paint of the vehicle that comes into contact with the impact device.

[0024] Preferably, the reset device is connected to or can be connected to the vehicle handling facility so as to keep the impact device in a non-operational position without contacting the obstacle during operation of the vehicle handling facility, for example, when the carrier is moved. In this way, for example, interference-free operation can be achieved.

[0025] For example, in gantry-type vehicle handling facilities, sudden impacts from moving devices may be introduced into the load-bearing structure, potentially causing erroneous detections by sensor devices. As a remedy, a reset device is preferably sized to keep the impact device in a non-operational position without contacting obstacles during operation of the vehicle handling facility.

[0026] Preferably, the reset device is or includes a spring element. For example, the spring element can be designed and / or arranged to elastically reset a deviation. Preferably, the spring element is or includes a metal body and / or a plastic body. For example, the metal can be particularly corrosion-resistant. The plastic can, for example, have good damping properties.

[0027] Spring elements may, for example, have at least one helical segment or helical spring segment, and may be designed, for example, at least in a segmental manner as a helical spring. Spring elements may, for example, have at least one rod segment, and may be designed, for example, at least in a segmental manner as a torsion bar spring and / or a beam spring. Spring elements may, for example, have at least one strip segment, and may be designed, for example, at least in a segmental manner as a bandfeder. The above variations represent only particularly preferred embodiments and do not reflect a complete list of possible variations.

[0028] Preferably, the end sections of the reset devices surround the protrusions fixed to the impact device and / or fixed to or capable of being fixed to the vehicle handling facility. "Surrounding" can be understood, for example, as completely surrounding the protrusion, surrounding at least half of the cross-section of the protrusion, and / or surrounding multiple sections distributed around the protrusion in the peripheral direction. For example, the protrusion may have a substantially circular cross-section, an angular cross-section, and / or other regular or irregular cross-sections. For example, the protrusion may be part of the impact device, such as an integral part and / or an end portion. For example, the protrusion may be fixed, such as welded or screwed, to the impact device and / or the vehicle handling facility and / or a reset support device capable of being connected to the vehicle handling facility. By surrounding the protrusion with the reset devices, a connection suitable for torque transmission can be structurally simplified, for example.

[0029] Preferably, the end sections of the reset devices are embedded in a housing formed on the impact device and / or in a housing formed or arranged on the vehicle handling facility. The housing may be designed, for example, as a hole, sleeve, retainer, clamp, slot, groove, and / or gripper. The housing may have, for example, a substantially circular cross-section, an angular cross-section, and / or other regular or irregular cross-sections. By embedding the reset devices into the housings, a connection that is structurally simple for torque transmission can be designed, for example.

[0030] The receiving part can be formed in the impact device and / or vehicle handling facility and / or in the reset support device that can be connected to the vehicle handling facility and / or installed thereon as a separate part or a section of a separate part.

[0031] The reset device can be directly fixed to the impact device and / or vehicle handling facility, for example, to achieve a particularly robust design structure. The reset device can also be indirectly fixed to the impact device and / or vehicle handling facility, for example, by connecting a damping device in the middle. The reset device can be fixed and / or can be fixed to the vehicle handling facility by connecting a reset support device in the middle, for example, to allow for the mounting of various types and / or optional existing reset devices or safety equipment.

[0032] The likely scenario is that safety equipment is placed within the environment of the vehicle handling facility, rather than being directly applied to the vehicle handling facility itself.

[0033] Preferably, the end section of the reset device is fixed to the impact device and / or to the vehicle handling facility or a reset support device fixed to or capable of being fixed to the vehicle handling facility, for example, in a releasable manner, shape-locking, force-locking and / or material-locking manner.

[0034] You can set a fixing and / or support method to prevent loss.

[0035] For example, when the reset device is or includes a helical spring, it is advantageous to arrange the spacing between any two adjacent turns in the relaxed state of the helical spring to be at most only the diameter of the helical wire, or the maximum transverse extension in the winding direction. By arranging the turns close to each other, a helical spring with relatively high spring stiffness can be used.

[0036] For example, when the reset device is or includes a helical spring, it is advantageous to arrange that, in the relaxed state of the helical spring, each pair of adjacent coils abut against each other. Thus, damping can be achieved, for example, based on the friction between the adjacent coils. The abutting coils can therefore lead to the attenuation of vibrations and thus to a rapid (re)occupancy of the non-operated position. Preferably, the friction can resist unintentional deviance of the impact device.

[0037] For example, if the safety device does not have a magnetic reset or a magnetic reset device, it can prevent interference caused by foreign objects attracted by magnetism.

[0038] Preferably, no other reset device is provided besides the aforementioned reset device. This allows for a simple design scheme in terms of the safety equipment's structure.

[0039] In particular, the aforementioned reset device can be configured to be the only reset device used (preferably elastically) to reset the impact device to the non-operational position.

[0040] The sensor device can be configured to detect when the impact device is in a non-operational position.

[0041] The sensor device can be optionally or additionally configured to detect that the impact device has deviated from the non-operational position into the operational position. The sensor device can be configured to detect the impact device deviating from the non-operational position into the operational position. This can, for example, trigger or enable the safety action of safety equipment.

[0042] For example, the control equipment of a safety device or a vehicle handling facility connected thereto may be configured to: deactivate the drive unit and / or output a prompt to the operator when it detects that the impact device is not in a non-operational position and / or detects that it is in an operational position deviating from the non-operational position.

[0043] The sensor device can be configured for non-contact detection of impact devices to provide, for example, a device insensitive to splashing water. Alternatively or additionally, the sensor device can be configured for contact detection of impact devices to provide, for example, a robust device.

[0044] The sensor device can be configured to perform inductive and / or capacitive detection of the impact device, for example, to provide a sensitive sensing device.

[0045] Preferably, a detection portion that can be detected by a sensor device is arranged on the impact device. The detection portion is, for example, an element coordinated with the sensor device for detection by the sensor device, or has such an element. This allows, for example, the position of the impact device to be reliably detected.

[0046] In particular, the positioning of the detection section can be configured to be variable, thereby adjusting the distance between the detection section and the sensor device. Therefore, for example, the detection characteristics can be matched to a specific installation location. This adjustability preferably allows for calibration using simple devices during assembly and / or site modifications. Preferred adjustment mechanisms include, for example, a continuously adjustable thread or a graded ratchet mechanism.

[0047] Optionally, the sensor device and the reset device are arranged on different sides of the foot section of the impact device. For comparison, consider a safety device in which the sensor device and the reset device are arranged, for example, on the same side of the foot section. In this comparative safety device, the reset device is preferably spaced sufficiently from the sensor device so that the reset device does not contact the sensor device in the event of a large deviation. In the currently preferred embodiment, by arranging the sensor device and the reset device on different sides of the impact device, collision between the sensor device and the reset device is preferably prevented even in the event of a large deviation of the impact device. Thus, the impact device and the reset device can, for example, be arranged relatively close in space, and a compact structural form can be achieved. Preferably, because the reset device is spatially close to the sensor device, the impact device can more quickly and reliably occupy a position clearly detectable by the sensor device.

[0048] Preferably, the sensor device and the reset device are arranged on opposite, especially opposing, sides of the foot section. This allows the connection between the reset device and the impact device to be installed very close to the sensor device, requiring very little structural space.

[0049] The sensor device can define the sensor axis.

[0050] Along the sensor axis, for example, the impact device being in a non-operational position and / or the impact device deviating from a non-operational position to an operational position can be detected.

[0051] The axis of the sensor and the axis of the reset device are preferably aligned with each other.

[0052] The axis of the sensor and the axis of the reset device may intersect, for example.

[0053] The axis of the sensor and the axis of the reset device can be offset by up to three times the diameter of the reset device and / or the sensor device. Preferably, the axis of the sensor and the axis of the reset device can be offset by up to twice the diameter of the reset device and / or the sensor device. More preferably, the axis of the sensor and the axis of the reset device can be offset by up to one time the diameter of the reset device and / or the sensor device.

[0054] In one embodiment of the invention, the sensor axis and the reset device axis can be arranged at opposite angles to each other.

[0055] According to a preferred embodiment of the invention, the impact device has a foot section, a head section, and an intermediate section connecting the foot section and the head section. The head section is preferably fixed to a safety device. The foot section is preferably coupled to a reset device and / or a sensor device. The intermediate section is preferably configured as a lever to convert small deviations of the intermediate section caused by contact with an obstacle into larger deviations of the foot section from a non-operational position to an operational position.

[0056] For example, in order to identify obstacles that come into contact with the vehicle handling facility and / or avoid contact with the vehicle handling unit, it is preferable to form a protruding section in the middle section, for example, extending beyond the vehicle handling unit, especially the lateral handling unit, especially the wheel washing brush, in the direction of the vehicle handling area, especially the washing area.

[0057] The shape and / or orientation of the prominent section is preferably matched with the shape of the vehicle handling facility and / or the vehicle handling unit carried by the vehicle handling facility and / or the shape of the vehicle handling area defined by the vehicle handling facility, such as the washing area.

[0058] Preferably, the protruding section is formed to extend beyond the sensor device and / or reset device toward the vehicle processing area, especially the washing area. This protects the sensor device and / or reset device from collisions with obstacles.

[0059] For example, a prominent section can have a shape that is essentially a triangular protrusion.

[0060] Preferably, the protruding section extends at least 20 cm, more preferably at least 50 cm, and more preferably at least 75 cm along the distance from the foot section to the head section. In this way, the safety device can be matched to various types of obstacle sizes.

[0061] At least the intermediate section can be formed of or comprise such a tube. The tube is a hollow body and therefore generally lighter than a solid body. By using a tube as an intermediate section or part of an intermediate section, the impact device can react more rapidly based on contact with the obstacle. Preferably, the protruding section is formed by at least one bend in the tube, for example, to avoid additional material in the area of ​​the protrusion.

[0062] A tube may, for example, have a circular cross-section, so as to have the same properties when contact occurs from different directions. A tube may, for example, have a non-circular cross-section, so as to exhibit different properties depending on the direction of contact.

[0063] Preferably, the head section is surrounded by an elastic cushioning device, which is preferably connected between the head section and the retaining device. This, for example, allows for elastic deflection of the impact device.

[0064] The task mentioned at the beginning is also solved by a vehicle processing facility according to the invention for processing, in particular cleaning and / or polishing vehicles, the vehicle processing facility having safety equipment of the type described above for contact-type obstacle detection and a support device, in particular a support column, for carrying the vehicle processing unit, wherein the safety equipment is mounted on the support device toward the vehicle processing area, in particular the vehicle washing area.

[0065] Safety equipment can, for example, ensure the safety of the load-bearing device by pointing towards the vehicle handling area. A vehicle handling unit, such as a wheel washing brush, is located behind the protruding section and specifically designed to ensure safety from the protruding section.

[0066] Advantageously, the impact device extends to or almost to the ground along the entire height of the bearing device.

[0067] The vehicle handling facility having the safety device according to the invention is preferably characterized in that the safety device has a rapid and reliable response when the impact device comes into contact with an obstacle.

[0068] Preferably, the arrangement of the vehicle handling unit on the vehicle handling facility defines a handling area, particularly a washing area, for vehicles. Preferably, optional protruding sections of safety equipment protrude from the support columns of the vehicle handling facility toward the handling area.

[0069] Preferably, the vehicle handling facility and / or safety equipment have a control device. The control device, for example, allows control of the vehicle handling facility or a portion thereof. Information from the sensor devices can preferably be processed by the control device.

[0070] Preferably, for signal transmission, the sensor device is connected to the control device to transmit a signal indicating whether the impact device is in a non-operational position or in an operational position deviating from the non-operational position. Thus, safety control can be achieved, for example, by means of the control device.

[0071] In particular, the control device can be configured to stop the movement of the carrier and / or vehicle handling unit when the impact device is detected to be in a maneuverable position by means of a sensor device. This can improve the operational safety of the vehicle handling facility.

[0072] Preferably, the sensor device is directly or indirectly connected to the drive mechanism of the vehicle handling facility to interrupt and / or accommodate the drive mechanism based on occupying a control position deviating from a non-control position. For example, the movement of the vehicle handling facility or the vehicle handling unit can be stopped. For example, the vehicle handling facility or vehicle handling unit can move away from an obstacle.

[0073] In particular, vehicle handling facilities may have display devices for showing prompts to users.

[0074] For example, the sensor device can be directly or indirectly connected to the display device so that, in the absence of an intermediate control device, when occupying a non-operational position deviating from the operation position, the signal output by the sensor device or its absence can be converted into a display on the display device.

[0075] Preferably, the control device is configured to display a prompt via a display device when a sensor device detects that the impact device has occupied the operating position. This particularly enables the display of any situation matching the condition to the user.

[0076] Preferably, the protruding section has its maximum protrusion at a height of approximately 20 cm to 100 cm above the vehicle handling or washing area. The mentioned height range is particularly useful for identifying obstacles, and is preferably independent of whether the obstacle is a passenger vehicle, a truck, a person, or other obstacle.

[0077] Vehicle handling facilities may in particular be washing facilities and / or polishing facilities. Preferred washing facilities may in particular be gantry-type washing facilities and / or washing lines.

[0078] Further advantageous embodiments of the vehicle handling facility according to the invention are derived from advantageous embodiments of the safety device according to the invention, and thus reference is made in this regard to the foregoing explanation. Attached Figure Description

Detailed Implementation

[0080] Figure 1 A vehicle handling facility 100 according to the present invention is illustrated schematically. The vehicle handling facility 100 is exemplarily a gantry-type washing facility.

[0081] The vehicle processing facility 100 includes a gantry-shaped support 102 for carrying multiple functional devices 104, and hereby exemplary includes two safety devices 108. The functional devices 104 are vehicle processing units, particularly side processing units, and especially wheel washing brushes 106. In addition to the wheel washing brushes 106, the vehicle processing facility 100 may also include other vehicle processing units not shown in the figures, such as side brushes, roof brushes, and / or drying devices.

[0082] The support device 102 exemplarily has two support columns 110 and a crossbeam 112 connecting these support columns. The support device 102, for example, can be perpendicular to... Figure 1 The planar component moves on the support surface via at least one drive device (not shown). As the support device 102 moves, the support column 110 exemplarily encloses the vehicle washing area 114, which is an example of a vehicle processing area.

[0083] Safety device 108 is fixed to the support device 102, currently fixed to the crossbeam 112, and protrudes from the support device 102 toward the vehicle washing area 114.

[0084] exist Figure 1 In the exemplary illustration, wheel wash brushes 106 extend from their respective support posts 110 into the washing area 114. Here, the wheel wash brushes 106 are not embedded in the hypothetical vehicle profile 116. For example, the vehicle profile 116 may be a space pre-defined by the vehicle handling facility 100 for properly parking the vehicle 118 to be handled by the vehicle handling facility 100.

[0085] Each of the two safety devices 108 has a retaining device 120, an impact device 122, a reset device 124, a sensor device 126, and an optional reset support device 128.

[0086] The retaining device 120 is currently fixed to the crossbeam 112 and holds the respective impact device 122, which is suspended downwards. Alternatively, the retaining device 120 may be fixed to the respective support column 110, for example. Other fixing points for the retaining device 120 are conceivable, especially in cases of other structural types of the vehicle handling facility 100.

[0087] For simplicity, only one safety device 108 will be discussed in detail below, because these safety devices 108 are designed symmetrically with respect to the central vertical plane of symmetry of the vehicle handling facility 100. The following statements apply accordingly to both safety devices 108.

[0088] The retaining device 120, which is fixed to the vehicle handling facility 100, can be fixed to the bearing device 102 in a movable manner, for example, it can be with gaps.

[0089] The impact device 122 is held by the holding device 120 so as to deflect from the non-operational position 130 to at least one operational position due to contact with an obstacle. For example, the stiffness of the impact device 122 is set to enable deflection. For example, the impact device 122 is held elastically and / or floatingly by the holding device 120.

[0090] Starting from the retaining device 120, the impact device 122 is configured to be substantially longitudinal and has a head section 132, a middle section 134, and a foot section 136. It is fixed to the retaining device via the head section 132. The middle section 134 is currently rod-shaped.

[0091] The head section 132 bends relative to the middle section 134 by approximately 90°. Similarly, the foot section 136 bends relative to the middle section 134 by approximately 90°. For example, the bends are made along the longitudinal direction of the vehicle handling facility 100.

[0092] The middle section 134 forms a protruding section 138 that faces the cleaning area 114. The protruding section 138 is currently formed in a basically triangular shape.

[0093] The protruding section 138 extends approximately 50 cm from the foot section 136 to the middle section 134, for example, to allow for contact detection of the widest possible range of heights of potential obstacles, including smaller ones. On the vehicle handling facility 100, the protruding section 138 extends to its furthest point approximately 40 cm above the placement surface in the vehicle washing area 114.

[0094] In the direction of travel of vehicle 118, the protruding section 138 is positioned in front of the wheel wash brush 106 so that an impending collision with the wheel wash brush can be detected.

[0095] Currently, to form sections 132, 134, and 136, the impact device 122 includes a curved tube, particularly made of a metallic material. Preferably, the tube is at least sectionally covered with a deformable material, such as foam. This reduces the risk of damage in the event of contact with an obstacle, such as vehicle 118.

[0096] The impact device is coupled to the reset device 124 at an end or end section 148 spaced apart from the retaining device 120. The end section 148 is included by the foot section 136. Currently, this coupling is achieved by connecting the foot section 136 to the reset device 124.

[0097] The reset device 124 is connected to the vehicle handling facility 100 at an end or end section 156 spaced apart from the impact device 122. Currently, this connection is achieved indirectly by connecting the end or end section 156 via an optional reset support device 128. The reset support device 128 is fixed to the support column 110.

[0098] The sensor device 126 is arranged at the end or end section 148 of the impact device 122, which is spaced apart from the holding device 120, and is laterally positioned next to the end section.

[0099] In the current example, the reset device 124 and the sensor device 126 are arranged on different sides of the foot section 136. In particular, the reset device 124 and the sensor device 126 are opposite each other with respect to the foot section 136, especially the end section 148.

[0100] In the present case, regarding the correct use of the height orientation and vehicle handling facility 100, the reset device 124 is arranged above the foot section 136, while the sensor device 126 is arranged below the foot section 136. In other embodiments of the invention, the opposite arrangement may be provided.

[0101] Currently, sensor device 126 is exemplarily a sensor device that performs detection non-contactly by means of sensing. Sensor device 126 is exemplarily fixed to vehicle handling facility 100, particularly to its respective support column 110. For this purpose, for example, separate retaining elements can be provided (…). Figures 3 to 5 and Figure 10 ).

[0102] The sensor device 126 is aligned, for example, with the non-operational position 130 of the impact device 122, and is configured, for example, to output a signal that specifically indicates that the impact device 122 occupies the non-operational position 130.

[0103] In the non-operational position 130, the impact device 122 may be oriented such that the middle section is perpendicular to the support surface of the vehicle 118 and extends vertically in particular.

[0104] The reset device 124 is currently securely connected to the impact device 122. Furthermore, the reset device 124 is currently securely connected to the reset support device 128. Accordingly, the reset device 124 can be supported, for example, on both sides.

[0105] In the safety device 108 according to the invention, torque can be transmitted via the connection of the reset device 124 to the impact device 122 and via the connection of the reset device 124 to the vehicle handling facility 100.

[0106] When the impact device 122 deviates from the non-operational position 130 to the operational position 150a, 150b due to contact with an obstacle, this causes not only the resetting device 124 to elongate or compress, but also to bend and / or twist. Therefore, the respective resetting devices 124 undergo superimposed deformation. This superimposed deformation, especially in the case of a small deviation, results in a relatively high resetting force. If the contact with the obstacle disappears, this will cause the impact device 122 to quickly and reliably return to the non-operational position 130.

[0107] Figure 3 The non-operational position 130 of the impact device 122 is shown when there is no contact with an obstacle that would cause a deviation. Figure 3 The wheel cleaning brush 106 has been removed.

[0108] Currently, the reset device 124 is a helical spring 140, which specifically defines the axis 142. The helical spring 140 is an example of a spring element 144 that forms and is included in the reset device 124.

[0109] Sensor device 126 defines sensor axis 146. Along sensor axis 146, for example, it is possible to detect that impact device 122 is in non-operational position 130. Alternatively, it is possible to detect that impact device 122 deviates from non-operational position 130 into operation position along sensor axis 146.

[0110] Currently, the reset device 124 and the sensor device 126 are arranged on opposite sides of the foot section 136 such that when the impact device 122 is in the non-operational position, the sensor axis 146 and the axis 142 of the reset device 124 are aligned with each other.

[0111] Starting from a non-operational position, contact with an obstacle will cause the impact device 122 to deviate into at least one operational position. Advantageously, deviating into multiple operational positions is possible. This will be referred to... Figure 4 and Figure 5 Let's discuss this.

[0112] Figure 4 and Figure 5 The operating positions of the impact device 122, exemplarily indicated by reference numerals 150a and 150b, are shown. Figure 4 and Figure 5 In the event that the obstacle (not shown in the figure) causes the impact device 122 to move in different directions from... Figure 3 The non-operational position 130 deviates from its respective operation position 150a, 150b.

[0113] In particular, Figure 4 In the example, the deviation occurs in the longitudinal direction 150c of the vehicle handling facility 100 relative to the direction of entry. Figure 5 In the example, the deviation occurs in the lateral direction 150d, which is oriented laterally and, in particular, perpendicularly to the longitudinal direction 150c.

[0114] In a corresponding manner, deviation in the opposite direction is possible, which is achieved through... Figures 2 to 5 The double arrows in the middle refer to the vertical direction 150c and the horizontal direction 150d.

[0115] It should be understood that, in particular, there is the possibility of deviation in the direction obtained by any superposition of the longitudinal direction 150c and the lateral direction 150d, i.e., preferably at an arbitrary angle to the direction of entry. Therefore, the safety device 108 has proven to be particularly diverse, and the vehicle handling facility 100 possesses a high degree of operational safety.

[0116] In terms of design structure, the end section 152 of the helical spring 140 that connects to the impact device 122 is, for example, securely connected to the end section 148 of the impact device 122. In a specific case, for example, a protrusion 170 is integrally constructed with the end section 148 of the impact device 122. In particular, the end section 152 is form-fitted onto the protrusion 170 and securely surrounds the protrusion.

[0117] For example, Figure 9 As shown, the receiving portion 154, which is implemented as a clamping device and is part of the reset support device 128, securely surrounds the end section 156 of the helical spring 140, which is connected to the reset support device 128. Here, the reset device 124 is form-locked into the receiving portion 154.

[0118] exist Figure 4 and Figure 5 When the impact device 122, as exemplarily shown, deviates from the non-operational position 130 to its respective operational positions 150a, 150b, the end sections 152, 156 of the reset device 124 shift or twist relative to each other. In the exemplary case, this relative movement causes the reset device 124 to bend into an S-shape, which is shown in the figure by the S-shaped deformation of axis 142. This bending or twisting acts as a reset force or reset torque to resist the deviance.

[0119] In addition, it particularly avoids unintentional deviation of the impact device 122, for example, when the vehicle handling facility 100 is moving on the support surface.

[0120] Apart from the reset device 124, there is no other reset device, thus the safety device 108 has a simple design and a compact structure.

[0121] As already described, the sensor device 126 is a non-contact sensing device. A detection portion 158 is arranged at the end section 148 of the impact device 122. Figures 3 to 5 , Figure 10 The probe portion 158 is constructed, for example, as a screw element, which is screwed into a thread (not shown) on the end section 148 and can be secured against loss, for example, by a lock nut.

[0122] The detection portion 158 can be screwed into the end section 148 to a greater or lesser extent in order to change the distance from the sensor device 126.

[0123] This, for example, allows the detection characteristics of the safety device 108 to be calibrated after the safety device 108 has been installed on the vehicle processing facility 100.

[0124] When the impact device 122 is in the non-operational position 130, the detection portion 158 is arranged, for example, close to the sensor head 160 of the sensor device 126. In this case, the sensor device 126 detects, for example, that the non-operational position 130 is occupied and outputs a corresponding signal.

[0125] The alternative can be configured to output a signal only when the position deviates from the non-operational position 130 to the operational positions 150a and 150b.

[0126] When the impact device 122 is deviated from the non-operational position 130 or deviated into the operational positions 150a, 150b, the detection portion 158 is no longer close to the sensor head 160, and the sensor device 126 does not detect the occupation of the non-operational position 130 and / or detects the occupation of the operational positions 150a, 150b. In this case, the sensor device 126 outputs a signal corresponding to the occupation of the operational positions 150a, 150b and / or the non-operational position 130.

[0127] The signal from sensor device 126 can be, for example, a digital signal. For instance, the signal from sensor device 126 can be a current value and / or a voltage value, including 0 amperes and / or 0 volts.

[0128] Control device 161 ( Figure 1 The control device 161 is electrically connected to the sensor device 126. The control device 161 is specifically configured to operate the vehicle handling facility 100, for example, to drive the drive unit 163 of the gantry cleaning facility to move on the support surface.

[0129] If the impact device 122 deviates from the non-operational position 130 to the operational position 150a, 150b due to contact with an obstacle, the control device 161 deactivates the drive device 163 in order to avoid damage to the obstacle and / or the vehicle handling facility 100.

[0130] If, for example, the impact device 122 is deflected into the operating positions 150a, 150b when the vehicle handling facility 100 is stationary, the control device 161 may lock the drive device 163.

[0131] If the impact device 122 returns to the non-operational position 130, the drive device 163 can be activated or reactivated, for example. It can be configured that prior operator approval is required at the control device 161.

[0132] For example, combining Figures 1 to 7 It can be seen that the protruding section 138 is formed to protrude from the bearing column 110 toward the vehicle washing area 114.

[0133] In the non-operational position 130, for example, the maximum distance 162 between the protruding section 138 and the support column 110 is greater than the maximum distance 164 between the reset device 124 and the reset support device 128 and the support column 110.

[0134] In the non-operational position 130, for example, the maximum spacing 162 of the protruding section 138 is greater than the maximum spacing 166 between the sensor device 126 and the support column 110. Therefore, there is a high probability that an obstacle will first come into contact with the impact device 122, thus avoiding damage to the support column 110.

[0135] Combination Figure 4 and Figure 5 It can be seen that the protruding section 138 is configured to protrude at least from the support post 110 to a degree sufficient to segmentally cover the wheel wash brush 106, especially the drive and / or brush disc of the wheel wash brush 106.

[0136] Since the impact device 122 extends almost the entire height of the gantry until it is close to the ground, almost the entire load-bearing column 110 can be safely secured in the direction of the inside of the gantry where the cleaning area is located.

[0137] Figure 8 An exemplary retaining device 120 is shown. The retaining device 120 holds the impact device 122, for example, between two support elements 168, which are preferably resilient and semi-shell-like, to facilitate the offset or pivoting of the impact device 122 relative to the bearing device 102.

[0138] at last, Figure 3 , Figure 6 , Figure 7 and Figure 9 As shown, for example, the coils 172 of the helical spring 140 are in contact with each other in the relaxed state of the helical spring 140. This causes friction between adjacent coils 172, especially when moving from the operating position 150a, 150b to the non-operating position 130. This situation can, for example, dampen the reset motion, thereby enabling a rapid return to the non-operating position 130 after deviation and preventing overshoot.
