Definitions
- the invention relates to an electro-dip painting device with
- electro-dip painting also called electrophoretic painting
- the paint constituents are separated in the paint bath under the influence of an electric field on the workpieces. It has proven to be expedient not to keep the electric field constant during the passage of the workpieces through the coating bath, but to vary along the path of movement, in particular with the distance traveled. Reason for this measure is, inter alia, that the build-up paint layer is an electrical resistance, which complicates the further construction of the paint layer.
- Object of the present invention is to provide an electric dip painting device of the type mentioned in such a way that it can be easily controlled, is flexible and causes less wear on the contactors.
- a controllable voltage regulation unit is arranged between each contact device and the associated workpiece;
- a position determining means is provided which determines the instantaneous position of each workpiece and outputs a corresponding signal to the controller;
- the at least one controller is designed so that it determines from the signal supplied to it of the position-determining device for each workpiece a voltage on which the workpiece is to be located at this position, and to the voltage regulation unit.
- the invention is therefore on the sectional division of the contact rail, which is connected to rail sections, omitted and used a galvanically continuous contact rail.
- a special voltage regulation unit is assigned to each workpiece. This is controlled according to the position of the workpiece so that at any time the workpiece is at the desired potential. In this way, a much more sensitive adjustment of the potentials on the workpieces can be accomplished as in the known division of the contact rail into individual sections. A change to another type of workpieces is easily possible only by programming measures. The absence of cuts in the contact rail has a favorable effect on the service life of the contact devices.
- the at least one controller may be the central controller of the device. This is especially in question where the conveyor comprises a conveyor chain and all workpieces move at the same speed.
- Modern devices have conveyor systems with independently moving, each bearing at least one workpiece weighing. Since these vehicles are generally "intelligent" themselves, ie have decentralized control, they can also be used for the purposes according to the invention be used.
- the position-determining device has a position code rail and, for each workpiece, a reading head which is moved along with the workpiece and is capable of reading out the local code of the position code rail.
- suitable position code rails are commercially relatively inexpensive - lent and have a high accuracy.
- a navigating system such as a laser-based or GPS-based system, may be used as the position-determining device.
- the position determining means comprises a presence sensor at the beginning of the movement path of the workpieces through the paint bath and speed sensors for the workpieces, wherein the controller is designed so that they from the detected
- Passing the presence sensor has elapsed can also be detected directly the distance traveled and from this the current position of each workpiece can be calculated.
- the distance measurement can be done by counting the passed chain links, working with wheels conveyor systems by counting the revolutions of the wheels.
- the drawing shows a total of three vehicle bodies Ia, Ib, Ic, which can think of immersed in a paint liquid filled with lacquer pool, as described in the above-mentioned DE 199 42 556 C2.
- the paint pool is not shown in FIG. 1, nor is the conveyor with which the various vehicle bodies Ia, Ib, Ic are moved continuously or intermittently through the paint pool.
- a suspension conveyor as it is shown as a conveyor 12 in DE 199 42 556 C2, a chain conveyor on which the workpieces are movably supported, but also a conveyor that makes use of individual, independently movable and controllable weighing.
- counter electrodes in particular anodes, placed in a known manner along the path of movement of the vehicle bodies Ia, Ib, Ic, as can also be seen in DE 199 42 556 C2.
- the electric field which occurs within the coating liquid between the counterelectrodes and the vehicle bodies Ia, Ib, Ic, the deposition of the paint constituents takes place on the vehicle bodies Ia, Ib, Ic.
- the ampere-hour number which has flowed between the counterelectrodes and the vehicle bodies Ia, Ib, Ic as they pass through the paint pool represents a direct measure of the thickness of the deposited paint layer.
- the Vehicle bodies Ia, Ib, Ic are connected during their movement through the paint bath with the corresponding pole of a DC voltage source 20, in the usual case of cataphoretic dip painting with the negative pole.
- a contact rail extends 2.
- This contact rail 2 is not interrupted on the entire length, thus does not have the usual in the art "cuts", So places where various portions of the contact rail 2 are electrically isolated attached to each other.
- the contact rail 2 is connected to a pole, preferably the negative pole, of the DC voltage source 20. It is generally sufficient if the DC voltage source 20 outputs a constant output voltage which corresponds to the maximum voltage to be applied to the vehicle bodies Ia, Ib, Ic.
- the other pole of the DC voltage source 20 is connected to the electrodes arranged along the path of movement, preferably anodes.
- Each vehicle body Ia, Ib, Ic is a contact shoe
- the contact shoes 3a, 3b, 3c are not connected directly to the respective vehicle bodies 1a, 1b, 1c but via a controllable voltage regulation unit 4a, 4b, 4c.
- the voltage regulation units 4a, 4b, 4c are designed such that, in accordance with a control signal supplied thereto by a controller 5 via a line 6a, 6b, 6c, the voltage lying on the contact rail 2 remains unchanged or changed, in general my reduced, can pass on to the corresponding vehicle body Ia, Ib, Ic.
- a reading head 8 a, 8 b, 8 c which is capable of reading the instantaneous position of the corresponding vehicle body 1 a, 1 b, 1 c from the position code rail 7.
- the signals read out by the reading heads 8a, 8b, 8c are supplied to the controller 5 via a respective line 9a, 9b, 9c.
- the controller 5 includes a memory in which is stored for each vehicle body Ia, Ib, Ic or at least for each type of vehicle body Ia, Ib, Ic, which is to be treated on the device, which voltage at which
- Place along the path of movement to the vehicle body in question Ia, Ib, Ic is to create.
- the electro-dip painting apparatus described above operates as follows:
- the controller 5 now outputs to the corresponding voltage regulation unit 4a, 4b, 4c via the line 6a, 6b, 6c from a corresponding signal, which ensures that the voltage regulation unit 4 actually generates the desired voltage from the voltage prevailing on the contact rail 2 voltage and to the vehicle body Ia, Ib, Ic lays.
- the reading head 8a, 8b, 8c transmits either continuously or after passing through small Weginkremente the respective position and the controller 5 regulates the voltage applied to the associated vehicle body Ia, Ib, Ic voltage via the voltage regulation units 4a, 4b, 4c.
- Ia, Ib, Ic which are connected to the same contact rail 2 to adjust while driving through the paint pool.
- the positioning device which was formed by the position code rail 7 and the read heads 8a, 8b, 8c in the embodiment described above, can of course also be replaced by other position determination devices.
- a navigating system based on laser control or GPS is usable.
- a sensor can be arranged at the entrance of the movement path through the paint pool, which reports the arrival of a vehicle body. From there, the respective position of the vehicle body is determined from its speed, which is constantly being determined and is monitored, and the elapsed time is calculated.
