Definitions

• the invention relates to a device for machining the surface of bodies having irregular contours in the form of a rotating body which is driven by a shaft which is guided therein and which can be adjusted against the surface to be machined and which consists of a plurality of sections which can be adjusted differently against the body to be machined. whose outer surface is the support for the means for processing the surface.
• washing brushes are provided, which extend vertically and horizontally and are designed to match the height or width of the usual car bodies, and which can be adjusted against the vehicle passing through the washing systems and clean or wash the body using water and cleaning agents .
• Polishing brushes can be connected downstream. The position of the brushes must in particular be adaptable to different vehicle dimensions, but if possible also to the different body shapes. This can be realized roughly with a program control that influences the brush setting. Different from the vertical
• the brush sections are non-rotatably arranged inner cylindrical and outer frustoconical brush bodies arranged on drive shaft sections which are connected to one another in an articulated manner.
• This washing brush adapts when starting against the vehicle roof to be cleaned, the contours of the roof in such a way that the off-center parts of the washing brush lower more.
• the wash brush sections come under the influence of their own weight including the weight of the drive shaft section against the surface to be cleaned. This in turn leads to the bristles bending, which impairs the cleaning effect of the brushes.
• the divisibility of such a washing brush is limited in the case of the complex construction that is otherwise to be accepted, and its adaptability is therefore also limited.
• this device cannot be used to individually adjust the brush sections against surfaces that extend essentially in the vertical direction, that is to say, for example, the longitudinal side surfaces of bodies.
• the invention has for its object to solve the problem of the individual loading of contours surfaces when machining such surfaces with the help of a rotating body, the outer surface of which is the carrier of the machining means or is formed by machining means, in such a way that all to be machined simultaneously surface parts can be optimally machined.
• a device of the type outlined at the outset which is characterized in that the sections of the rotary body are penetrated eccentrically by a drive shaft, on which drive wheels acting on each section from the inside are arranged and at least one relative to the drive shaft as also in relation to the section supported by it, smoothly rotatable guidance.
• the driven sections of the rotary body under the action of the torque resulting from the drive individual limited by the run-up of the respective section against the surface section acted upon by it pivoting movements around the drive shaft, which results in that with sufficient subdivision of the rotary body practically all parts of the surface also pronounced contours are optimally applied, both over the height or width of the total area to be machined as well as over its length, since the adjustment of the sections immediately and automatically the contours and adapts to the contour.
• the rough division can take place in a known manner by displacing the rotating body, as a G-fit against the surface to be machined, if necessary also by correspondingly inclining the rotating body.
• a mode of operation is also possible in which initially all sections of the rotating body in operation are swung out to a maximum and the individual sections are then pivoted back individually according to the surface contours by the body to be machined which is brought up to the rotating body.
• the sections of the rotating bodies preferably consist of rigid hollow cylinder sections.
• the hollow cylinder sections can be driven by pinions arranged on the drive shaft, which mesh with the internal toothed rings assigned to the hollow cylinder sections.
• the drive of the hollow cylinder sections with expediently leading friction wheels in a circumferential groove on the inside of the hollow cylinder sections proves to be particularly low-wear.
• the sections of the rotary body consist of endless belts in the manner of drive belts which are supported against driving wheels and deflection wheels arranged at a distance therefrom.
• driving wheels and deflection wheels arranged at a distance therefrom.
• Belts designed in the manner of V-belts, the tread, in particular the drive wheels, can be roughened to increase the grip.
• the design of the pairings can vary within wide limits. It can be a disk provided with recesses for the drive and for a possibly provided pivoting movement, in extreme cases a ring with an inwardly projecting shoulder with a passage for the drive shaft, but also around an arm mounted on the drive shaft, which is provided at the free end with supporting bodies which come to bear against the rotating body sections.
• a larger swivel range is obtained if the guides project laterally at the level of the drive over the drive wheels so that the belts can only be applied to the rear of the drive wheels. This can be dispensed with if the deflection wheel is designed to be significantly larger than the driving wheel.
• the guides can be arranged on the drive shaft with the insertion of slide and ball bearings. Accordingly, rollers can also be provided on the guides, against which the rotating body sections are supported. In order to bring about and maintain a clearance between the sections required for the unimpaired individual pivoting mobility of the rotary body sections, spacer sleeves can be provided on the drive shaft, which are supported indirectly or directly against the driving wheels.
• a stop extending through the rotary body sections limits the pivoting movement of the sections and prevents their undesired complete circulation.
• the stop is expediently adjustable to different swivel ranges.
• return springs counteracting the pivoting movement of the rotary body sections can be provided, which, when the device is at a standstill, cause the sections to pivot back into the starting position.
• a spring with free travel can be provided so that the return spring does not impair the desired pivoting movement of the section. If necessary, the spring can also be used to reduce the pivoting force.
• the applications described above with or without a return spring provide a particularly gentle treatment of the surface to be processed. In addition, they save on machining resources such as bristles, polishing discs and the like.
• the device according to the invention can also be provided with return springs acting on the rotary body sections, which prevent the sections from pivoting solely by the torque resulting from the drive.
• the sections are first pressed against the force of the spring by the body to be machined, which is brought up to the rotating body and corresponds to the surface contours of the body individually swiveled.
• Pressure spring can be used in this way to realize a surface processing that requires a greater pressure of the processing means against the surface to be machined, as may be necessary, for example, when grinding and polishing workpieces.
• the effect of independent readjustment with increasing wear of the processing means proves to be additionally advantageous.
• the device according to the invention it is also advantageously possible to move the supply of cleaning water into the interior of the rotary body and to apply water to the surface to be machined through the jacket surface. This enables a targeted application of water, which results in considerable water savings.
• the water supply can be integrated into the stop limiting the swiveling movement of the cylinder sections.
