    Transport device and method for dip painting
    The invention relates to a transport device for transporting an object, such as a body, along a treatment line, the transport device comprising a transport unit which can be moved in a transport direction along the treatment line, a rotary shaft mounted on the transport unit for holding the object to be treated and introducing it into the treatment line, and an in includes a support arm that rises to a working position to support the transport unit.
    Furthermore, the invention relates to a system for dip painting a body comprising a plunge pool, a guide structure and such a transport device.
    The invention further relates to the use of such a transport device.
    Furthermore, the invention relates to a method for conveying an object, in particular a body, along a treatment route, a transport device with an upstanding support arm being guided along the treatment route and / or a return route.
    Various systems for conveying bodies along a treatment line are known from the prior art, a treatment line comprising at least one station for surface treatment of an object, such as a vehicle body. Such stations can be, for example, immersion baths or painting booths, into which bodies are introduced for painting. In such a process, large bodies in particular should be able to be transported in a space-saving and stable manner.
    A transport device for transporting large vehicle bodies usually comprises a transport unit on which a rotary shaft with a receptacle for the object to be treated is mounted, the object being immersed, for example, in a plunge pool via the rotary shaft. For stabilization, a substantially vertically arranged support arm can be provided on the transport unit, which prevents the transport device from tipping over when loaded. To one
    To provide 2/24 supporting force of sufficient extent, this support arm must have a great height of, for example, 2 m or more, whereby leverage is used. Such transport devices are usually returned laterally along the treatment line in order to be loaded again. This results in the disadvantage that arrivals with such a transport device are wide and therefore a large space requirement for these systems.
    The object of the invention is therefore to provide a transport device of the type mentioned at the outset with which a space-saving process route can be implemented.
    The further object of the invention is to provide a system of the type mentioned at the outset which requires little space.
    Furthermore, it is an object of the invention to provide a use for a transport device of the type mentioned at the outset.
    The procedural object of the invention is to provide a method of the type mentioned at the beginning with which a space-saving process route can be implemented.
    The first object is achieved according to the invention in that the support arm can be moved in a transport device of the type mentioned at the outset, so that a height of the transport device can be changed.
    An advantage achieved with the invention can be seen in particular in that a height of the transport device can be reduced, as a result of which a return path for the transport device can run below a treatment line. For this purpose, the support arm can be designed to be removable, telescopic and / or pivotable.
    In order to ensure adequate stabilization, it is advantageous if the support arm is arranged substantially perpendicular to the direction of transport in the working position.
    Another advantage is obtained when the support arm is pivotally attached to the transport unit, a pivot axis being arranged perpendicular to the rotary shaft and / or in the transport direction. This allows the support arm to reduce the height
    3/24 of the transport device are aligned essentially parallel to the rotary shaft, which is why no additional space for the support arm has to be planned.
    It is further favorable if the support arm can be moved between two end positions which enclose an angle between 0 ° and 180 °, preferably of at least 60 °, in particular approximately 90 °, a first end position representing the working position and a second end position representing a return position . This ensures a sufficient gain in space, for example when the vertical support arm is pivoted by 60 °, its height is reduced to half. The support arm preferably has a lower height in the second end position, which is why it is taken along the return path.
    In order to fix the support arm in the working or return position and to secure it against tilting or arbitrary pivoting, it is expedient if a means for fixing the support arm is provided in the end positions.
    In addition, a counterpart, for example a beam, a rail or any support, can be provided for the support arm, as a result of which the transport device is prevented from tipping over and is stabilized along a treatment path. So that the support arm can be guided as wear-free and with little friction or effort along the counterpart, it is expedient if a rotatable guide element is provided, which is positioned at an upper end of the support arm. A rotatable guide element can comprise, for example, at least one rolling element. Alternatively, a sliding element can also be provided.
    The further object is achieved according to the invention in that in a system of the type mentioned at the outset, the plunge pool is mounted at a distance from a floor on which the system is located, the transport device being able to be guided along a treatment path above and along a return path below the plunge pool.
    An advantage achieved with this system can be seen in particular in the fact that the system can be designed to be narrow, which means that it takes up little space. For this purpose, the plunge pool can in particular be mounted on a frame or on supports.
    4/24
    It is furthermore favorable if the guide construction has a guide rail, in which the rotatable guide element engages in the working position. This ensures a quick release and stabilization of the transport device by the support arm. Furthermore, the rotatable guide element can be guided in the guide rail with little friction. It is advantageous if the guide rail runs parallel to the treatment section. In addition, it is advantageous if the guide rail is arranged in a region of the upper end of the support arm.
    A further advantage is obtained if the guide construction has a support rail in which the rotatable guide element engages in the return position. This ensures stabilization of the support arm, whereby a force on a pivotable attachment of the support arm to the transport device is reduced. Such a fastening can be, for example, a hinge or a similar joint which can be pivoted about an axis. It is advantageous if a force on the fastening is reduced, since this increases the lifespan of the fastening.
    It is furthermore expedient if the guide construction has a travel rail in which at least one rolling element of the transport unit engages along the treatment route. As a result, the transport device for treating the object can be guided along a defined path.
    Furthermore, it is expedient if the guide structure has a further travel rail in which at least one rolling element of the transport unit engages along the return path. As a result, the transport device can be returned along a defined path after the treatment of the object.
    In order to move the transport device from a first section, which runs in the transport direction along the treatment section, to the return section lying underneath and running in the opposite direction, it is expedient if a lifting device is provided for lifting and / or lowering the transport device.
    In order to move the transport device from a first route, which runs in the transport direction along the treatment route, to a further route
    5/24 favorable if a swivel table is provided, with an axis of rotation of the swivel table being aligned perpendicular to the travel rail. The further route can, for example, lie next to the first route and run along a further treatment route. The further route runs in the opposite direction to the transport direction. This can be, for example, a first section of another plant; thus two systems can be connected to the swivel table. As an alternative to this, the transport device can also be returned to a start of the treatment route along this further route.
    The further object is achieved when using a transport device according to the invention for dip painting bodywork.
    An advantage achieved with this use can be seen in the fact that with this transport device the height of the support arm is reduced and the transport device can subsequently be led back below the treatment section to save space.
    The procedural object is achieved if, in a method of the type mentioned in the introduction, the object is delivered to one end of the treatment section and the device is returned to a starting point without the article along a return section below the treatment section.
    An advantage achieved with this method can be seen in particular in the fact that the treatment of the object can take place in a confined space.
    It is advantageous if a support arm of the device is moved from a working position to a return position at the end of the treatment section or at the beginning of the return section and from a return position to a working position at the beginning of the treatment section or at one end of the return section. This ensures that the transport device is supported by the support arm during the treatment of the object. Furthermore, the support arm is arranged along a return path in a return position, whereby a height of the transport device is reduced. An advantage achieved in this way can be seen in particular in the fact that the treatment of the object can also take place in a small space in addition to the narrow space.
    6/24
    In order to provide sufficient space for the support arm to be folded in, it is expedient if a holder for the object is pivoted or rotated downward with a rotary movement. For this purpose, for example, a rotary shaft to which the holder is attached can be rotated so that the holder is positioned below the rotary shaft.
    It is also expedient if the device is lowered to the return path at the end of the treatment path by means of a lifting device and raised to the treatment path at the end of the return path by means of a lifting device.
    The invention is explained in detail below. The drawings to which reference is made show:
    Figures 1a and b a transport device with a pivotable support arm.
    2 shows a further view of the transport device;
    3a to f each show a detailed view of a fixing device;
    4 shows part of a first embodiment of a system;
    5 shows a further part of the first embodiment of the system;
    6a to b show part of a further embodiment of the system.
    A first embodiment of a transport device 1 is shown in FIGS. 1a and b. The transport device 1 comprises a transport unit 2, a rotating shaft mounted thereon, a support arm 4, and a holder 5 for an object, in particular for a vehicle body.
    In Fig. 1a, the transport device 1 is shown in a working setting, wherein the support arm 4 assumes a working position in which it protrudes substantially vertically. In this embodiment, a main pipe 3 is connected to the transport unit 2, for example screwed to it. The rotary shaft is at least partially guided within the main tube 3, a sliding bearing being provided at the ends of the main tube 3 for rotatably supporting the rotary shaft. The main pipe 3 serves to support the rotary shaft and can be designed over the entire surface as shown in FIG. 1a. Alternatively, the main pipe 3 can have a plurality of recesses for weight and material reduction. Instead of the main pipe 3, an alternative can also be used
    7/24
    Device for supporting the rotary shaft is provided or the rotary shaft is connected to the transport unit 2 in a self-supporting manner. The bracket 5 is fixed to the rotary shaft and oriented upwards in this illustration. In operation, the holder 5 can be rotated about an axis of rotation of the rotary shaft, for example in order to introduce the object into a plunge pool or to guide it through a plunge pool or to pivot it. For this purpose, the rotary shaft is mounted on the transport unit 2 essentially perpendicular to a transport direction R. It can further be provided that the holder 5 is rotatably mounted about one or more additional axes. A rolling element 7 is provided at an upper end of the support arm 4, which reduces frictional resistance when the support arm 4 is supported. Alternatively, one or more sliding elements or several rolling elements 7 can also be provided for this.
    In Fig. 1b, the transport device 1 is shown in a return setting, wherein the support arm 4 assumes a return position in which it is tilted essentially 90 ° to the working position, whereby a height of the entire transport device 1 is reduced. However, the return position is not limited to an arrangement shown. In principle, the support arm 4 can be folded in at any angle in order to reduce a height of the transport device 1 and to be brought into the return position. The working and return position of the support arm 4 preferably enclose an angle between 60 ° and 90 °. In the return setting, the holder 5 is rotated on a side of the rotary shaft facing away from the support arm 4. This provides sufficient space for the folded-in support arm 4. The support arm 4 is fixed both in the working position and in the return position by a, in particular releasable, fixing device 6.
    Fig. 2 shows a further view of the transport device 1 in the working setting, in which further rolling elements 7 and a hinge can be seen. These rolling elements 7 are arranged on the transport unit 2 in order to reduce frictional resistance when it is moved. The hinge is fixed on the one hand to the transport unit 2 and on the other hand to the support arm 4 in order to pivotally connect the support arm 4 to the transport unit 2. Alternatively, other connections can also be provided, which enable a pivotable connection.

    FIG. 3a shows a detailed view of the fixing device 6, with the support arm 4 being fixed in the working position. Here, a fixing pin 9 engages in a recess 11 in the hinge pin 13, whereby it is secured against rotation and the support arm 4 is fixed, in particular against inadvertent folding or pivoting.
    3b shows the fixing device 6, the support arm 4 being fixed in the return position. In the hinge pin 13 there is one for each position of the support arm 4
    Recess 11 is provided so that the support arm 4 can be brought into the recesses 11 corresponding, discrete positions. In the embodiment shown, a recess 11 is provided for the working and for the return position. The fixing bolt 9 is pressed into the recess 11 by means of the spring element 10. In order to pivot the support arm 4, a spring force must be counteracted and the fixing bolt 9 must be moved out of the recess 11.
    In Fig. 3c, the fixing device 6 is shown in a plan view. The hinge 8 is shown in an orientation corresponding to the working position. The fixing bolt 9 is pressed into the recess 11, which cannot be seen, by means of the spring element 10. For example, a disk 12 arranged on the fixing bolt 9 can serve as the contact surface for the spring element 10.
    A cross section along the line III-III is shown in FIG. 3d, wherein the fixing bolt 9 engages in the recess 11 in the hinge bolt 13.
    3e and f show a side and a holistic view of the fixing device 6.
    Fig. 4 shows part of a system for dip painting objects, the support arm 4 is in the working position and engages with the rolling element 7 in a guide rail 14, whereby the transport device 1 is stabilized. The transport unit 2 engages with further rolling elements 7 in a travel rail 15, as a result of which this can be guided in a transport direction R according to FIG. 1a. The transport direction R is perpendicular to a view surface. The bracket 5 is
    9/24 oriented upwards in this view, but rotatable around the axis of the rotary shaft during operation, in particular along a treatment path.
    FIG. 5 shows a further part of a system for dip painting objects, the support arm 4 being in the return position and engaging with the rolling element 7 in a support rail 16. Thus, the weight of the support arm 4 is at least partially on the support rail 16, whereby a load on the hinge 8 is reduced. Furthermore, the holder 5 is rotated downward to make room for the support arm 4. Due to the space gained by the folded-in support arm 4, the transport device 1 can be guided below a treatment section, for example a plunge pool, the plunge pool being arranged on a frame 17 for this purpose. This enables a slim design of a system for dip painting bodywork. A width of the system is therefore essentially limited to a width of the frame 17 or the plunge pool. However, it can be provided that optional units, such as drive units or control units, increase the width of the system. A guide rail 15 is also provided along the return path for returning the transport device 1.
    In general, a transport device 1 with an object to be treated is guided in a transport direction R along a treatment path and, after the object has been released, is returned to a starting point along a return path at the end of the treatment path. In the exemplary embodiment shown, a return path can lie below the treatment path.
    As an alternative to the pivotable support arm 4, it can be provided that the support arm 4 can be telescopically extended or retracted, as a result of which a height of the transport device 1 can also be reduced and the transport device 1 can be returned below the treatment section in a space-saving manner.
    In a further advantageous embodiment, the support arm 4 can be detachably connected to the transport device 1, for example by means of a plug connection. In this case, the support arm 4 can be detached from the transport device 1 and placed on it and fixed, as a result of which the height of the transport device 1 is also reduced and the return path can lie below the treatment path.
    10/24
    As an alternative to this, the support arm 4 detached from the transport device 1 can be returned along a further route, for example hanging, and provided at the beginning of the treatment route and connected to a transport unit 2. In such an embodiment, the transport unit 2 can also be returned below the treatment section in a space-saving manner.
    A lifting device can be provided in order to move the transport device 1 or the transport unit 2 from a treatment section to a return section below it or from a return section to a treatment section above it. It is expedient for this if the lifting device decouples the rolling elements 7 from the respective rails 14, 15, 16. Here, for example, the rolling element 7 can be brought out of the guide rail 14 at the upper end of the support arm 4, the entire transport device 1 can be lowered, the support arm 4 can be folded in, and the rolling element 7 can subsequently be introduced into a support rail 16. A lifting device can be, for example, a height-adjustable or tiltable travel rail 14, which ensures that the transport device 1 can engage in a travel rail 14 arranged on the return path.
    6a to b show a further embodiment of a system for dip painting a vehicle body. Here, a return path is arranged parallel to the treatment path. The guide rails 14 of the return path and the treatment path are connected via a curved guide rail 18. Furthermore, a swivel table 19 is provided. In operation, the transport device 1 reaches the swivel table 19 and is fixed in it. As a result, the transport device 1 is moved along the curved guide rail 18, as a result of which the swivel table 19 is rotated about an axis with the transport device 1. The transport device 1 can be released again and guided further along a process route along a travel rail 15. This can be done, for example, along a return route or a further treatment route. Thus, for example, several treatment routes can be linked together.
