Definitions

  • the invention relates to a metering system for a coating installation for, in particular, serial coating of workpieces according to the preamble of claim 1.
  • Dosing systems for coating systems in practice require considerable and sometimes difficult to implement requirements, in particular the accuracy, which in many cases is to be absolute and at least ⁇ 1% of the nominal value in terms of dosing fluctuations, with high repeat accuracy in terms of temperature and viscosity and pressure fluctuations. Because of the required accuracy preferably continuous volume control is required.
  • the constituents of the metering system must be as free from dead space as possible, inter alia, to avoid hardening. Particular requirements arise in the metering of special coating materials such as NAD material (non-aqueous polymer dispersion), for which, among other things, special measuring equipment is required, or for materials in the application of which high dosing pressure is achieved, for example in the case of PUR up to 400 bar.
  • NAD material non-aqueous polymer dispersion
  • the volume flow ie the flow rate, which may be in typical cases, for example, between 2 and 50 cc / sec.
  • Other requirements relate to the permissible transient response times of the system ( ⁇ 40 ms to ⁇ 5% of the nominal value), freely programmable pre-pressure setting with short reaction time ( ⁇ 100 ms) and automatic dynamic adjustment of the pre-pressure for changes in the viscosity of the coating material.
  • the possibility of automatic calibration in case of material changes and low delay times at start of operation In general, not only the plant and maintenance costs, but in particular with regard to the assembly in or on application robots and the weight and dimensions of the system components should be as low as possible.
  • Continuous dosing systems have fundamental advantages such as relatively low costs (low costs), continuous material flow, large dosing range, short cycle times without refilling times and compact dimensions.
  • known continuous metering systems are too inaccurate for some applications. They may include pressure regulators with simple control circuits, with which only a pressure control or using a flow cell, a volume control is performed, or flow regulators, in whose control circuits, for example, control valves can be used as an actuator and flow cells as actual value.
  • the object of the invention is to enable continuous metering with high metering accuracy and low reaction delays in a simple manner.
  • the two-stage or multi-stage metering system described here can be realized with minimal construction, control and maintenance costs as a pure flow system with the possibility of continuous, continuous metering, which in contrast to known continuous systems offers the greatest possible advantage Dosing accuracy (usually less than 1% deviation from the setpoint) has. A comparable accuracy was previously achievable only with discontinuous piston dosing.
  • the system works according to the master-slave principle with the first metering stage as master and the second metering stage as slave.
  • first metering advantageously a simple, compact, low-cost and low-maintenance metering device can be used in a conventional manner such as a low-wear and low-maintenance flow regulator with a metering valve as an actuator or an even simpler dosing pressure regulator.
  • second metering stage required for fine metering, for example, a piston metering device may be used which may be similar to conventional piston metering devices, but unlike these does not deliver discontinuously with periodic filling and emptying, but only the continuous coating material from the first metering stage for enlargement or reduce the flow rate.
  • the Feindosierer can be smaller, more compact and lighter than discontinuous Kolbendosierer, making it particularly well suited for mounting in or on a robot arm (eg on axis 3) or traveling (on axis 7), which in turn because of the short Removal of the dosing system from the applicator to increase the dosing accuracy contributes. Since the Feindosierer is mechanically less stressed, it is also less susceptible to wear and maintenance than conventional piston dispensers.
  • the first metering device preferably operates in a closed loop.
  • fine dosing does not always have to be done in its own closed loop.
  • Similar advantages also arise when other devices, including continuously conveying or continuous flow metering pumps of known type, whose conveying effect can be reversed so that they can both increase and decrease the pressure or volume flow of the coating material, are used as fine metering devices. and whose drive motor can be controlled to correct the pressure or volume flow value set by the first metering device.
  • working with rotating spindles screw pumps can be used appropriately.
  • Another possibility is a fine metering using a Sollwertt controlled applicator nozzle as a second metering device, for example in the closed loop in the EP 1 346 775 A1 known manner, according to which the main needle valve of an atomizer is used as an actuator, which may also contain the electric or pneumatic drive of this metering valve and / or an associated flow measuring device.
  • the fine meter usually only intervenes when the discharge rate set by the upstream metering stage does not exactly correspond to the specified target values, that is to say must be corrected.
  • the fine meter can adjust the pressure or volume of the coating material.
  • the Feindosierer in sudden changes in the setpoint for pressure or outflow rate then necessary pressure adjustment realize extremely short term.
  • the quality of application is significantly improved during seam sealing, especially at the beginning and end of the applied seam.
  • the invention has other advantages such u.a. the possibility of precisely dosed application of both very small and large volume flows as well as universal usability for different coating tasks and materials.
  • the materials which can be metered according to the invention include, for example, thixotropic material, NAD material and PUR.
  • the invention is suitable for any coating materials including paint, but especially for highly viscous coating material, as required for example in adhesive applications (such as Mosfalzkleben in vehicle bodies), for underbody protection or in the sealant application.
  • adhesive applications such as Tufalzkleben in vehicle bodies
  • the invention proves to be particularly advantageous. Similar advantages arise in also applied by air atomization material for the underbody protection of bodies.
  • the invention is always advantageous if a defined form must be set before opening the main valve (eg the main needle) of the applicator.
  • the pressure or the volume flow of the coating material supplied to the applicator can be regulated, in each case with the aim of precise and demand-controllable metering of the applied coating material.
  • pressure regulation it can be assumed that each pressure value at the inlet of the applicator corresponds to a known, precisely determined outflow quantity value of the applied material, which is given in compensable dependence on other factors such as temperature and / or viscosity, for example by the geometric shape and size of an application nozzle.
  • a nozzle suitable for the regulated pressure is to be used for the desired dosage or, for a given nozzle, the corresponding pressure at the nozzle is to be generated.
  • pressure or volume flow is regulated depends on the practical requirements of the particular application.
  • the respective coating material play a role, but may also be preferred for the same material, a pressure control system because of its lower cost or a volume flow control system because of its higher accuracy.
  • Fig. 1 Dosing system shown is designed so that it can be used either for pressure control as well as for flow control. Not all components are required for each case.
  • the coating material to be applied by an applicator 10 for example sealing material required for vehicle bodies or parts thereof, is supplied from a material supply device 12 through an input line 13 and a material pressure regulator 14 to a first metering device 20 and from there through a connecting line 21 to a second metering device 30. From the output of the second metering device 30, the coating material flows through a line 31, for example, a hose, to the input of the applicator 10.
  • the material delivery is effected by the pressure prevailing in the lines 13, 21 and 31 pressure.
  • the dashed lines represent e.g. electrical or pneumatic signal control lines.
  • the material pressure regulator 14 serves to regulate the admission pressure of the metering system at the material input of the first metering device 20 and contains for this purpose a switched into the input line 13 control valve 22 and an associated pressure sensor 23.
  • the control valve 22 can in a conventional manner of a in the application control 40th contained associated control device (not shown) in the closed loop in response to the actual pressure value, which is measured by the pressure sensor 23 at the material output of the control valve 22, and a predetermined desired form setpoint value to be controlled.
  • the material pressure regulator 14 is set to a constant material pressure which is greater than the maximum pressure required in the application operation in the system.
  • the first metering device 20 includes a switched into the connecting line 21 metering valve 22, which serves in a conventional manner as an actuator of a closed loop and is operated for example by an electric reversible motor M20 with associated gear G, as well as its own pressure sensor 23, the pressure at the material outlet of the metering valve 22 measures.
  • A likewise contained in the application control 40 associated control device (not shown), the motor M20 in response to the actual pressure value of the pressure sensor 23 and / or in response to an actual value at the output of the second metering device 30 and of the in the usual way with the Actual value control of compared setpoint values.
  • the setpoint values are variable as needed for the desired dosage of the coating material during the application and are specified to the control loop by the higher-level automatic system control (not shown).
  • the second metering device 30 is used for fine metering of the coating material and contains in the illustrated example, a cylinder unit 32 in which a piston 33 is displaceable by a reversible motor M30 via a gear G in both directions.
  • the piston delimits the first cylinder chamber 34, which has a material input connected to the connection line 21 and a material outlet connected to the line 31 and, moreover, is closed in a pressure-tight manner.
  • the cylinder unit 32 the known from coating plants piston dispensers (for example EP 1 252 936 . EP 1 314 483 . EP 1 384 885 etc.) or also known per se piston pumps, of which it differs, however, by its explained below differently in principle different function and operation as an actuator of a closed loop.
  • the connecting line 21 contains between the material outlet of the first metering device 20 and the material inlet of the first cylinder chamber 34, a check valve 35 to prevent additional pressure build-up by the fine metering a pressure check to the metering valve 22.
  • a flow measuring cell 37 is connected to the line 31, which measures the volume flow of the coating material flowing to the applicator 10 with an equally possible mode of operation of the system and feeds this actual value to the associated control device in the application control 40 ,
  • the control device can control the cylinder unit 32 of the second metering device 30 serving as an actuator for direct volume flow control.
  • the flow measuring cell 37 measures the volume flow of the coating material flowing to the applicator 10, which results as a result of both metering devices 20 and 30, it may also be expedient to additionally control the control circuit of the first metering device with the measured value of the flow measuring cell 37. With knowledge of the respective pressure at both metering devices, both control loops can be controlled separately. The measured values of the flow measuring cell 37 can be converted in the application control 40 into corresponding pressure values.
  • the flow measuring cell 37 could also be dispensed with.
  • an additional pressure sensor 42 directly to the material inlet of the applicator 10.
  • the measured value of this pressure sensor 42 is not necessary for the actual dosing control according to the above explanations, but it can e.g. in the application control 40 in the adaptation of the system serve to eliminate the influences of temperature and / or viscosity.
  • the coating material in a circulation circuit can pass through the applicator 10, as is known per se in coating systems.
  • the line 31 leading to the applicator 10 is connected to a return line 51 via a changeover valve 50, which is closed during the application and is opened when the applicator 10 is closed.
  • the circulation loop does not have to go to the applicator 10 or even, as in this embodiment, through the applicator 10.

  • the circulation circuit can pass through the cylinder unit 32 as shown.
  • the return line 51 in this case opens into a material inlet of the second cylinder chamber 39, which is located on the side opposite to the first cylinder chamber 34 side of the piston 33, and connected to a material outlet of the second cylinder chamber 39 output line 51 'then forms the continuation of the circulation circuit.
  • the output line 51 ' is connected to the illustrated direction changeover valve 53, from which the circulation circuit continues back to the circulation connection 52 in front of the inlet of the material supply device 12.
  • the function of the switching valve 53 is to selectively connect the cylinder chamber 39 via the outlet line 51 'of the circulation circuit either to the circulation port 52 or via the counter-pressure line 55 to the input line 13 of the metering system. Since the second cylinder chamber 39 is closed pressure-tight except for the inlets and outlets of the circulation circuit, this embodiment provides a simple way, that during application with closed switching valve 50, the second cylinder chamber 39 via the Wegeumschaltventil 53 with the material supply pressure of the dosing can be applied.
  • the pressurization has the advantage that the metering with the motor M30 must apply for adjusting movements of the piston 33 required for fine dosage only relatively small forces required to overcome a pressure difference between the two cylinder chambers 34 and 39.
  • the construction of the back pressure advantageously allows a smaller and more compact design of the Feindosierers with respect to the drive, which in turn allows an improvement in the accuracy and the reaction time. If the circulation circuit does not pass through the cylinder unit 32, the switching valve 53 can be omitted and the back pressure in the second cylinder chamber 39 can be derived through the conduit 55 directly from the material supply.
  • the counter pressure in the second cylinder chamber 39 could also be generated by a pressure source (eg a pneumatic system) separate from the material supply. Further, the pressure value supporting the piston movement in the second cylinder chamber 39 could be changeable according to the desired movements of the piston 33, whereby overpressure or underpressure with respect to the first cylinder chamber 34 can result.

  • the metering drive of the piston 33 which regulates in accordance with the double arrow 57, only has to overcome the difference between the pressure P2 in the first cylinder chamber 34, through which the material can flow continuously at controlled pressure or volume flow, and the assisting pressure P1 in the second cylinder chamber 39.
  • Such an actuator can on the embodiment according to Fig. 1 Be useful for any other control loops, possibly even without the pressure support.
  • Fig. 3 is a replacement model of the control circuits of the dosing system according to Fig. 1 represented in his training as a pressure regulator with fine dosage. It can serve to simulate the control behavior and to carry out calculations which may be required for the realization of the various functions and for the mutual control coordination of the two metering devices with respect to each other.
  • the first metering device 20 is connected via the connecting line 21 to the second metering device 30, which serves as a fine metering device, from which the hose line 31 leads to the applicator.
