Definitions

  • the invention relates to a device for transporting car bodies along a treatment path with at least one dipping tank, comprising at least one transport unit with a pivot axis for receiving a car body and for introducing the same into the at least one dipping tank and a conveyor device with which the transport unit can be transported along the treatment path in a conveyor device, wherein a guide device is arranged along the treatment path, which cooperates at least temporarily with a driver which is connected to the pivot axis, wherein the guide device is designed to set the pivot axis in a pivoting movement via the driver for introducing and removing the car body into the dipping tank.
  • the invention relates to a return unit for returning transport units for car bodies, comprising a conveyor arranged along a path, in particular along a straight line, which is designed to cooperate with the transport units and to convey the transport units along the path, wherein the return unit has at least one drive for the conveyor.
  • the invention relates to a lifting station for a particularly vertical transport of transport units for car bodies between a working level and a base level, comprising receptacles for the transport units.
  • car bodies usually go through several immersion tanks in which treatment or
  • Coating fluids are located there.
  • the car bodies are guided along a treatment line using suitable transport units, each of which accommodates a single car body.
  • the car bodies are then transported into the respective dipping tanks via the transport unit. This can be achieved by swiveling them in and out by 180°, or by rotating them completely through 360°. Movement mechanisms are also known in which the car body is first placed approximately vertically into a dipping tank and then positioned approximately horizontally. and is then led out of the plunge pool approximately vertically.
  • the corresponding transport units comprise a first motor, with which the transport unit as such can be moved along the treatment path in the conveying direction. Furthermore, a second motor is provided, with which the pivot axis can be actuated, thus enabling the car bodies to be pivoted in and out.
  • a suitable guide device in the form of a rail is provided, which is indirectly connected to the pivot axis and interacts with a driver that is connected to the pivot axis.
  • the driver is guided in such a way that it causes the car body to rotate in and out of a dip tank through a deflection in the guide rail. Therefore, no separate motor is required to move the pivot axis.
  • a disadvantage, however, is that high forces act on the rails in the rotation area due to the large mass of the transport unit and the car body attached to it.
  • Systems in which a car body is moved passively into and out of a dipping tank without a separate motor usually comprise a conveyor system with which the transport unit for the car body can be moved along the treatment line.
  • the movement of the car body into and out of the tank is controlled via a rail and its shape.
  • the rail usually has a V-shaped recess in the area of the dipping tank.
  • the driver is designed as a frame with at least two bolt-like extensions, which are arranged so that the first bolt moves downwards upon reaching the V-shaped recess and then upwards, thereby rotating the pivot axis of the transport unit.
  • the frame is adapted to the V-shaped recess and is approximately rectangular in shape.
  • the frame is connected to the pivot axis.
  • a system of this type is known in the prior art as RoDip® M.
  • the object of the invention is to provide a device of the type mentioned above with which occurring forces can be easily handled.
  • the guide device has a first guide element with interrupted areas along the treatment path and a second guide element for taking over the guidance of the transport unit in the interrupted areas.
  • the invention provides the particular advantage that, due to the various guide elements, the forces occurring in different areas are taken into account and the guide elements are adapted accordingly. While in those areas in which the transport device, including the body attached to it (usually weighing several tons in total), takes place largely without major load peaks, very high forces occur when the body is rotated in and out of a dip tank with the given masses.
  • the first guide element is interrupted and, in the interrupted areas, the guiding work for the transport unit is taken over by a second guide element.
  • the guide elements are coordinated in such a way that the occurring forces are taken into account. This means that the second guide element, which is arranged in the interrupted areas, can handle higher forces without lasting wear.
  • the interrupted areas essentially correspond to the areas in which the dip tanks are arranged.
  • the transport unit including the body fastened to it, is then moved along a treatment section with the first guide element until an interruption, after which the second guide element, in the area of a dip tank, takes over the guidance of the transport unit, including the pivot axis, and causes the body to be rotated into the dip tank automatically and without the assistance of a motor.
  • the body is rotated out of the dip tank via the second guide element. Swiveling in and out is therefore passive.
  • the first guide device can then take over the guidance of the transport unit.
  • the concept of the invention can thus also be seen in combining various guide elements in such a way that high-performance guide elements are located in those areas where high forces occur, while guide elements with lower force capacity can be arranged in those areas where lower forces occur.
  • the guide elements are thus suitably designed and optimized with respect to the forces occurring at various positions along the treatment path.
  • the first guide element and the second guide element are preferably each arranged above a, in particular upper, level of the immersion tank(s), particularly preferably stationary. This also applies if one or more treatment devices other than immersion tanks are provided. If several treatment devices such as immersion tanks are provided, the first guide element and the second guide element are arranged along a transport path at least partially, preferably completely, above an upper level of the respective treatment device, so that guidance or transport of a Bodywork above, and treatment of the same bodywork in one or all treatment facilities, such as immersion tanks, takes place below an imaginary level.
  • the imaginary level which separates guidance from treatment, refers to the respective treatment facility, such as an immersion tank.
  • the first guide element and the second guide element are arranged in particular such that at least one of these guide elements seamlessly guides the transport unit, in particular above a treatment volume.
  • the treatment volume lies below an area defined by the guidance provided by the guide elements.
  • the first guide element is preferably designed as a guide rail.
  • the guide rail has the interrupted sections.
  • the guide rail does not have to absorb high forces and can therefore be designed relatively simply.
  • the second guide element can be designed as an arrangement of rollers, which are arranged in particular transversely to the conveying direction.
  • the arrangement of rollers interacts with the carrier of the transport unit.
  • the carrier can be designed as a roller wheel with a pin.
  • the carrier is designed so that it can interact with both the first guide element and the second guide element.
  • the interaction of the rollers with the roller wheel of the carrier allows for good force absorption in the area of the dipping tank.
  • the roller wheel also has a pin for this purpose. The pin interacts with the guide rail. As soon as the guide rail is left, the second guide element connects with the rollers. The roller wheel then engages with the rollers, causing the pivot axis to rotate and thus the body to be pivoted into the dipping tank.
  • the first guide element can then follow again, so that the body is first moved along a predetermined path through the dipping tank before the second guide element follows and, through the interaction of the roller wheel with the rollers, the body is rotated out of the dipping tank.
  • the rollers can be extended in the conveying direction so that the body is rotated both in and out through the interaction of the roller wheel with the rollers, thus achieving a 360° rotation.
  • the rollers have a suitable structure on the outside, which allows interaction with the rollers of the roller arrangement.
  • the rollers are arranged transversely to the conveying direction.
  • the rollers are preferably rotatably mounted to minimize wear. In principle, a gear with a rack could also be provided for this purpose, although this would be less advantageous in terms of wear.
  • the guidance can be assigned to the first guide element and the second guide element automatically, without the need for a separate control system.
  • a motor for rotating the transport device in and out of a dip tank can also be omitted.
  • either the pin or the roller wheel engages with one of the guide elements.
  • a shared guide can also be provided in the transition areas, allowing for a section-by-section transfer of guidance from the pin to the roller wheel of the carrier.
  • the conveyor device is preferably designed as a conveyor chain.
  • the conveyor chain can comprise at least one, preferably several, receiving shoes, which carry the transport unit in the conveying direction.
  • the conveyor chain can be designed to be closed all the way around.
  • the conveyor chain thus runs in a circle, driven by a motor provided for this purpose.
  • the receiving shoes allow the transport unit and thus also the body attached to it to be carried in the conveying direction.
  • a particular advantage of a device according to the invention is that only one conveyor chain is required, which is arranged on one side of the device in the conveying direction. On the other, opposite side (transverse to the conveying direction), the pivot axis can be mounted so as to rotate passively. This makes it possible to reduce the width of the device (again viewed transversely to the conveying direction).
  • the conveying device as well as the first conveying element and the second conveying element are preferably arranged outside a housing so that any maintenance and/or servicing work can be carried out more easily because it is not necessary to work within the volume defined by the housing.
  • the transport unit can preferably have at least one pickup which is connected to a carrying device, in particular the receiving shoes, of the conveyor device cooperates so that the conveyor device moves the transport unit in the conveying direction. It is particularly preferred that the at least one pickup is arranged so as to be displaceable perpendicular to the conveyor device.
  • the at least one pickup can be fixed in a first position, in which the conveyor device conveys the transport unit in the conveying direction, and can be brought into a second position, in which the conveyor device does not convey the transport unit when the latter is in operation. This makes it possible to decouple the transport unit from the conveyor device.
  • the at least one pickup is set so that the conveyor device takes the transport unit with it. Usually, two pickups are provided for this purpose per transport unit.
  • a first pickup can be arranged on the front of the transport unit in the conveying direction, and a second pickup on the rear.
  • the pickups work together with the aforementioned receiving shoes.
  • the transport unit can be decoupled from the conveyor device by moving the pickup(s). This is particularly important because normally a large number of transport units are moved one after the other along the treatment line via the conveyor system.
  • all transport units come to a standstill. If a transport unit cannot be moved out of an immersion tank due to a malfunction, the situation arises for rectifying the problem.
  • the transport unit causing the malfunction can be decoupled from the conveyor system, just like subsequent transport units, by moving their movable pickups into a second position so that they are no longer conveyed, the transport units at the front in the conveying direction can be extended and work can begin on rectifying the malfunction with good accessibility to the problem area.
  • the transport unit can advantageously comprise at least one friction rail, in particular an upper friction rail and a lower friction rail.
  • the friction rails are designed to interact with friction wheels to effect a movement of the transport unit.
  • the device advantageously comprises friction wheels which interact with the friction rail(s) to move the transport unit. A corresponding movement is particularly necessary for coupling and uncoupling the Transport units via lifting stations as well as for return transport of the transport units.
  • the invention provides for a first lifting station to be arranged upstream of the treatment line and/or a second lifting station to be arranged downstream.
  • the device according to the invention is fundamentally constructed such that the transport units are conveyed on a working plane.
  • the immersion tanks are arranged below the working plane.
  • Below the immersion tanks is a base plane.
  • the transport units are guided in a circle along the working plane and the second lifting device, as well as a return unit and the first lifting station.
  • This allows, among other things, a housing to be arranged directly above the immersion tanks so that the transport unit, which is moved via the conveyor device, preferably a conveyor chain, can be enclosed within a housing.
  • the conveyor device can be arranged outside this housing.
  • the transport unit is carried along without bearings on the opposite side.
  • the housing can thus enclose the transport unit with minimal space requirements, and the conveyor device can be arranged outside the housing.
  • a so-called imbricated seal is used for sealing. This makes maintenance easy, as all parts within the housing, except for the swivel mechanism of the transport unit, are easily accessible. At the same time, space requirements are minimized.
  • the first lifting station is configured to move the transport unit from the base level to the working level. Furthermore, the second lifting station is configured to move the transport unit from the working level to the base level.
  • Both the first and second lifting stations can have mounts for the transport unit. Typically, both lifting stations have corresponding mounts.
  • the mounts can be designed identically for both lifting stations.
  • the first lifting station and/or the second lifting station have at least one motor and at least one further conveyor chain driven by the motor and running along a height of the lifting station, wherein the further conveyor chain carries the receptacles.
  • the conveyor chains are preferably arranged parallel to one another.
  • the first lifting station and/or the second lifting station have several additional driven conveyor chains. In principle, both lifting stations are designed identically. Both lifting stations can comprise, for example, two to five additional conveyor chains for one drive.
  • the additional conveyor chains are jointly driven by a single motor of a lifting station.
  • the additional conveyor chains are designed to circulate along the height of the respective lifting station and thus allow the holders to be transported in a circle towards a height of the system. The number of chains is determined by the forces encountered.
  • the holders advantageously have an upper holder part and a lower holder part, with a motor with a friction drive arranged on the lower holder part.
  • the friction drive with a friction wheel in conjunction with a lower friction rail of the transport unit, can take over the transport unit at the end of the treatment section.
  • the pick-up shoes release the transport unit and push it towards the holder.
  • the friction drive with the motor provided for this purpose and the friction wheel engages the lower friction rail of the transport unit and moves the transport unit further into the holder.
  • the transport unit is firmly fixed in the holder by means of a form-fitting and/or force-fitting connection.
  • a fixing position is defined, for example, by an end position, which is triggered by a light barrier or a limit switch.
  • a return unit for the transport unit can be arranged between the first lifting station and the second lifting station, with which the transport unit can be moved from the second lifting station to the first lifting station.
  • the at least one transport unit usually a plurality of transport units, is guided in a circle, as already explained above.
  • the return unit can comprise several spaced friction wheels, which interact with the upper friction rail of the transport unit in order to convey the transport unit back to the first lifting station.
  • the friction rail is an upper friction rail of the transport unit, so that the friction wheels press from above onto the upper friction rail of the transport unit and thus move the transport unit towards the first
  • one or more motors are mounted on a return unit, and belts are provided to drive the individual friction wheels.
