Definitions
- the invention relates to a roof machine according to the preamble of claim 1.
- roof machines are known and in use in the painting lines of automobile plants.
- the known roof machines generally consist of an elongated, box-like roof beam, which is located across the assembly line within the spray booth and is suspended in the middle of the ceiling in such a way that it can be lowered and raised.
- a likewise beam-like holder for the atomizers hangs by means of arms, this holder beam being able to be moved horizontally back and forth relative to the actual roof beam (pendulum movement) and rotatable about its horizontal axis.
- the entire supply elements for the atomizers namely the metering pumps, the control and changeover valves for the paint, and the pneumatic valves, as well as the drive motors and gears for the pendulum and rotary movements of the mounting beam, are housed in the roof beam, in some cases also the drive motor for the up and down movement of the roof beam itself.
- the known roof beams are very heavy and large in volume, which not only requires very rigid roof structures and strong drive motors for the beam movement, but above all the occurrence of considerable flow turbulence in the spray booth brings with it.
- the object of the present invention is therefore to improve the known roof machines of the type mentioned at the outset in such a way that they disturb as little as possible a uniform air flow from top to bottom in the spray booth, are easy to assemble and install and contribute to the spray booth of dust and lubricant vapors keep clear.
- the solution to this problem results from the characterizing features of claim 1. '
- the roof beam is held on both ends by vertical columns, the drives being in one vertical column and the supply elements in the other vertical column.
- the roof beam which extends through the spray booth thus only contains the atomizers, a drive shaft for the atomizers and their supply hoses, which makes it possible to design the roof beam as a cylinder of comparatively small diameter.
- a Such roof beams as has also been shown by smoke tests, can hardly hinder the air flow, so that there is no major air turbulence.
- FIG. 1 shows a roof machine with a horizontal roof beam 10, which is mounted on vertical columns 11 and 12 at both ends.
- the roof beam 10 extends across a conveyor belt 13 on which an automobile body 14 is located.
- 15a, 16a and 17a denote the atomizing elements protruding from the roof beam 10 of three rotary atomizers mounted in the roof beam 10.
- FIG. 2A and 2B show the left and right side of the roof machine of Fig. 1 in a detailed vertical section.
- the vertical column 11 of rectangular cross section shown in FIG. 2A includes a bracket 20 to which a bearing 21 is attached.
- the bearing 21 receives the tapered left end 10a of the circular cross-section roof beam 10, such that the roof beam 10 is rotatable about a longitudinal axis.
- the console 20 is guided up and down in the column 11, the drive for this vertical movement of the console 20 and thus of the roof beam 10 being effected by a motor 22 fixedly attached in the upper region of the column 11.
- the power transmission from the motor 22 to the bracket 20 consists of a chain 23.
- a counterweight hangs on a steel cable and is connected to the bracket 20 via a deflection roller.
- the opening required for the up and down movement of the roof beam 10 is sealed with a circumferential plastic band 26 such that the column jacket is closed in every height position of the roof beam 10.
- Further drive motors are accommodated in the foundation of the column 10, namely the motors 27, 28 and 29.
- the motor 27 serves to rotate the roof beam 10 about its longitudinal axis, the force being transmitted to the console 20 by means of a torque shaft 30.
- the motors 28 and 29 serve to drive the atomizers 15, 16, 17 relative to the roof beam 10, as will be explained in detail later.
- the right vertical column 12 shown in FIG. 2B corresponds in its outer dimensions to the left column 11 just described and likewise has a console which can be moved up and down and is labeled 31.
- a console which can be moved up and down and is labeled 31.
- the components required for the paint supply are attached to the console 31, that is to say metering pumps 34, control valves 35 and paint mixing valves 36.
- the pneumatic components required for rotating the atomizers are also located on this console 31.
- an energy guide chain 37 is attached to the console 31 , which takes all - not shown - supply hoses to the components located on the console 31 and covers the entire vertical stroke of the console 31, so that there can be no hose kinks.
- the weight compensation by means of a counterweight and the sealing of the lifting opening by a revolving conveyor belt 39 are identical to those of the vertical column 11.
- the atomizers 15, 16 and 17 are accommodated in the beam 10, and are mounted on carriages 40, 41 and 42 which run on rails 44 and 45 fastened to the inner wall of the roof beam 10.
- a horizontal shaft 46 passes through the carriages, which is designed as a counter-rotating spindle at both ends, and are connected to this in a force-locking manner.
- the two outer carriages 40 and 42 are connected by means of a lock nut, and that of the middle carriage 41 by a shaft collar. This makes it understandable that when the shaft 46 rotates, the two outer atomizers 15 and 17 move synchronously towards or away from the middle atomizer 16, whereas the middle atomizer 16 remains stationary. In the case of a translatory movement of the shaft 46 to the right or left, however, the three atomizers 15, 16, 17 are also displaced together.
- a thrust rotary joint 48 which is displaceable on a linear guide 49 which is formed on the inner casing of a bushing 50 which is rotatably mounted in the roof beam 10.
- the displacement of the joint 48 is brought about by a crank 52 projecting from an eccentric 51; the eccentric 51 is driven by the motor 28 already mentioned via a shaft and a deflection gear.
- the bushing 50 and thus the joint 48 are rotated by the motor 29, also mentioned above, via a shaft, a deflection gear and a toothed belt 53.
- the atomizers 15, 16, 17 protrude from the roof beam 10 with their atomizer members 15a, 16a, 17a.
- the bushings of at least the two outer atomizers 15 and 17 through the roof beam wall are designed as drawers 55, so that the beam wall remains closed with each displacement of the atomizer.
- the atomizers 15, 16 and 17 are connected via connecting tubes (not shown) to the ink supply elements located on the console 31 of the vertical column 12; The connections for compressed air and high voltage - also not shown - are also made from this side.
- the roof machine works as follows: If the arrival of an automobile body to be sprayed is detected, the outer atomizers 15 and 17 are first brought into the position corresponding to the body width by rotating the shaft 46 and the entire roof beam 10 is lowered to the height required for spraying the body bow. Thereupon, the atomizers 15, 16, 17 are set into a reciprocating movement (horizontal pendulum movement) by means of the shaft 46 and the eccentric 51 and caused to start the spraying process. After spraying the body bow, the roof beam 10 is raised to the height required for spraying the body roof and then lowered again to that for spraying the horizontal body rear. Finally, the roof beam is lowered still further, with the roof beam rotating at the same time by approximately 90 ° in order to spray the vertical rear end face from behind. The roof bar 10 then returns to its raised position with the atomizer elements pointing vertically downward.
- the switching and control processes for paint, compressed air and high voltage to be carried out in this process are known to the person skilled in the art, so that an explanation is unnecessary.
- an extremely aerodynamically efficient roof machine is achieved because the roof beam lying in the flow path of the ventilation air (flow from top to bottom) has only a comparatively small expansion (small diameter) and is aerodynamically favorable due to its cylindrical shape, namely in every rotational position.
- the small diameter results from the fact that in Neither drive motors and gearboxes, but only a drive shaft, nor paint supply components, but only connecting hoses, can be accommodated.
- Another great advantage is that the drive shaft can be fed from one side and the connecting hoses from the other side to the atomizers, which prevents damage to the hoses.
- the requirements for freedom from dust are also largely taken into account because the dust part of the elements requiring lubrication is located in the closed columns.
- the two columns 11 and 12 are located outside the vertical walls of the spray booth, ie only the roof beam 10 and the synchronizing shaft are located within the spray booth itself.
- the columns 11 and 12 can also be designed as open frames.
- the roof machine can undergo numerous modifications without leaving the scope of the invention. If, for example, the degree of freedom of pivoting (rotation of the roof beam) is not required for the atomizers, the roof beam can be provided with a teardrop-shaped covering, making it even more flow-efficient. However, if an additional degree of freedom of movement is required for the atomizers, namely a co-movement with the body, then it is possible to design the two vertical columns to be movable on rails parallel to the assembly line.
