Definitions

  • the invention relates to a road marking vehicle with at least one paint spray gun and at least one bead spreading device which is connected to the bead container by means of a connecting line.
  • the self-monitoring tests are tests carried out by the contractor (or his representative) to determine whether whether the quality properties of the marking materials and the finished performance meet the contractual requirements.
  • the contractor must carry out the self-monitoring tests during the execution with the necessary care and to the required extent.
  • the desired amount of pearls is determined by the speed of the spreader roller, regardless of whether enough pearls also get from the pearl container onto the roller.
  • the per path unit The desired amount of pearls is determined by installing a corresponding pinion, which specifies the speed ratio of the vehicle wheel and spreader roller. If, for any reason, the pearl feed line to the spreader roller is blocked or even blocked, or if the driver does not notice that the pearl container is empty, line sections with insufficient pearl quantity or even without pearls can be mistakenly laid. Even if a wrong sprocket is accidentally inserted, pearls are not scattered in the prescribed amount.
  • test described also does not allow any statements to be made as to whether the prescribed amount of pearls has been laid evenly over the entire route.
  • control tests or external surveillance are prescribed, which include, among other things, checking the amount of material laid on the marked route and with regard to the laid color, a random check of the color film thickness.
  • the invention has for its object to provide a marking vehicle, which allows a reliable and constant monitoring of the scattered amount of pearls directly in the manufacture of reflective marking lines and moreover for the first time offers the possibility of automatically recording the monitoring result, so that it can be used for a control is available through the authorities and can also be used for billing purposes.
  • Ultrasonic flowmeters based on the Doppler principle have been available on the market for many years, but have so far been used practically exclusively for measuring liquids, in particular in the chemical industry for measuring corrosive liquids and for measuring the flow of waste water, whereby in any case, the systems are permanently installed.
  • Indirect ultrasonic flow measurement of bulk materials, such as reflective pearls has not yet been considered because there were apparently concerns about the feasibility of an accurate measurement.
  • the installation of such a measuring system on a work vehicle and a measurement while driving have not been considered.
  • the experts have obviously not yet recognized the great advantages that an application of ultrasonic flow measurement offers to the important control of pearl scattering.
  • this flow meter Since the ultrasonic measuring head is only on the outside of a suitable one Pipe section is installed, this flow meter has no parts to be moved by the beads, is therefore not subject to abrasion and wear and avoids the risk of obstructing the flow path of the beads. If for some reason no pearls arrive at the measuring point, for example because the pearl container is empty or the supply line is blocked, the flow rate is measured by the ultrasonic meter so that the driver is immediately alerted.
  • an identical ultrasonic measuring head is also installed for the continuous monitoring of the amount of ink laid and thus for the continuous control and registration of the ink layer thickness.
  • a direct flow measurement of the installed paint has therefore not yet been possible and is therefore not provided for in the official control guidelines. Rather, as for the control of the scattered amount of pearls, laborious and time-consuming self-monitoring tests and control tests of the quantity and layer thickness of the laid paint are prescribed, whereby the test of the color film thickness is also only required can be carried out on a random basis.
  • pages 124 to 126 it is intended to test the wet film thickness of color markings on a sample sheet using a wet film thickness meter. This test sheet must be placed in front of the paint spray gun of the moving marking machine and run over without changing the speed or other settings of the marking machine, the measurement having to be carried out immediately after the running over.
  • both the laid color and the scattered glass beads are continuously monitored and registered on the basis of an ultrasound flow measurement, many of the previously required checking and writing work are dispensed with, and both the person responsible for the marking and the authorities are available printed receipts are available, which make it easy to reliably check the quality of the work performed and can also be used for billing purposes. Subsequent checks of the amount of material and color film thickness can be dispensed with, and the risk of accidents during the marking work is reduced, since there is no longer any need for the driver to leave the vehicle in between and to inspect the marking.
  • the invention is based on the single figure in a schematically illustrated embodiment Block diagram explained in more detail.
  • the figure shows only the elements necessary for understanding the invention.
  • the road marking vehicle not shown in any more detail, then has a bead container 1 for reflex beads 2 and a bead scattering device 4, which is connected to the bead container 1 by means of a connecting line 3.
  • the bead spreading device 4 is a bead gun operated with compressed air.
  • a paint tank 7 for the paint 8 to be laid and a paint spray gun 10 operated with compressed air, which is connected to the paint tank 7 by means of a connecting line 9, are installed on the marking vehicle.
  • the connecting lines 3 and 9 each contain a special pipe section 5 or 11, which consists of an ultrasonic conductive material.
  • an ultrasonic measuring head 6 or 12 is attached for non-contact flow measurement according to the principle of the Doppler effect, for example by gluing with an epoxy resin.
  • Ultrasonic flowmeters have been known for many years (for example under the trade name BESTOBELL DOPPLER ULTRASONIC FLOWMETER from BESTOBELL MOBREY AG, D Weg, Switzerland), but have so far been used practically exclusively for the flow measurement of liquids.
  • these ultrasonic flowmeters are particularly suitable for measuring the flow of corrosive liquids, industrial sludges, waste water in sewage treatment plants and the like same used.
  • the flow measurement is based on a measurement of the frequency change that an ultrasound beam sent by the measuring head experiences when it is reflected at imperfections, for example from bubbles or boundary layers created by turbulence, or also from impurities in the flowing liquid.
  • the electrical signal emitted by the measuring head is proportional to the flow rate and thus, for a given pipe cross section, the throughput in volume units per unit of time.
  • the analog output signals of the two ultrasound measuring heads 6 and 12 are passed to an electronic evaluation circuit which, in the exemplary embodiment under consideration, consists of an analog-digital converter 13, a computing circuit 14 performing the arithmetic conversion of the signals in the form of a microprocessor and a digital-analog Converter 15 is made.
  • a speedometer is also installed on the marking vehicle, which in the example under consideration consists of a pulse generator 17, which delivers a certain number of pulses per path unit, for example 100 pulses per meter, and a frequency-to-DC converter 18, which is one of the pulse repetition frequency and so that DC voltage proportional to the vehicle speed delivers.
  • a path counter 16 indicating the distance traveled is connected to the converter 18, and its output signal 18a representing the vehicle speed is transmitted on the one hand to the analog-digital converter 13 and on the other hand to a speed indicator 19.
  • the speedometer can also be used from a tachometer generator or another neten measuring device.
  • K1 means a calibration factor for the color flow
  • D1 the throughput of the color in volume units per unit of time
  • K2 a calibration factor for the beads
  • D2 the throughput of the beads in units of weight per unit of time
  • V vehicle speed
  • W width of the drawn marking line.
  • the throughput D1 results from the flow rate measured by the ultrasonic measuring head 12, and the calibration factor K1 is selected, for example, such that the output signal 24 emitted by the digital / analog converter 15, which represents the ink layer thickness S, in Voltage range between 0 and 2.5 V corresponds to a layer thickness range between 0 and 1000 microns.
  • the output signal 24 is applied to a display device 21, which directly displays the installed ink layer thickness in microns, and to Given registration device 22, which also receives a signal 18b representing the vehicle speed from the converter 18. This speed signal controls the paper feed of the register device so that the values S and P are recorded in writing depending on the path.
  • the throughput D2 of the beads also results directly from the measured flow rate of the beads for a given cross section of the tube section 5 and given specific bead weight.
  • the calibration factor K2 is selected, for example, so that the other output signal 23, which represents the scattered amount of pearls P, corresponds to a pearl quantity range between 0 and 70 kg / km in the voltage range between 0 and 2.5 V.
  • the output signal 23 is sent to a display device 20, which directly shows the amount of pearl scattered in kg / km, and also to the registration device 22.
  • a digital switch 25 connected to the microprocessor 14 permits the setting of the line width W and the desired ink layer thickness and amount of pearls by selecting the relevant calibration factors K1 and K2.
  • the driver After this setting of the digital switch and after setting the compressed air actuating the paint spray gun and the pearl gun to the desired fixed values, the driver only needs to keep an eye on the two display devices 20 and 21 during the marking work and ensure that he maintains a constant driving speed t maintains that the pointers of both display devices 20 and 21 always display the desired values for the color layer thickness S or the scattered amount of pearls P.
  • these values are recorded in the recording device 22 in a continuous or intermittent manner in the form of continuous or dotted curves, for example after each curve section of one meter or a few meters, for example.
  • the arrangement according to the invention which is comparatively simple and inexpensive to implement with commercially available instruments and can be installed without difficulty on all existing road marking vehicles, represents a surprising improvement, the advantages of which in terms of simplification, time savings and The reliability of the monitoring cannot be overestimated either by the person responsible for the marking or by the authority.
  • the daily output can be significantly increased with the road marking vehicle according to the invention.
  • a further developed embodiment of the invention has an automatic control of both the amount of paint emitted by the paint spray gun 10 per unit of time and the beads scattered by the bead spreader 4 per unit of time as a function of the vehicle speed in such a way that the driver is no longer forced to constantly maintain his driving speed by observing the Check display devices 20 and 21 and correct if necessary.
  • the quantities determining the quantities of paint or pearls emitted in the example under consideration the compressed air actuating the paint spray gun and the pearl pistol, are controlled as a function of the speed signal 18c emitted by the converter 18, as is indicated by dash-dotted lines in the figure.
  • the amount of paint and pearls laid increases as the vehicle speed increases and decreases as the vehicle speed decreases, such that the predetermined color layer thickness and quantity of pearls remain constant within a certain driving speed range in which the driver can choose his driving speed as desired.
  • the measurement signals are only available after a certain time, which depends on the time constant of this flow measurement and is approximately one second. Therefore the output signals 23 and 24 displayed on the display devices 20 and 21 and recorded in the registration device 22 are faulty each time the bead scattering device 4 and the paint spray gun 10 are switched on, although the marking naturally begins immediately after said switching on.
  • a correction circuit with two inputs is provided in the microprocessor 14, which is connected to two switches 26 and 27 via an input circuit 28 used for level adjustment. The switch 26 is closed when the bead spreader 4 is switched on, and the switch 27 is closed when the paint spray gun 10 is switched on.
  • this e correction circuit After each switch-on the flow values obtained are modified by means of an e-function with a fixed time constant of typically one second, whereby the time constant of the flow measurement is at least approximately compensated.
  • the output signal which occurs after switching on and which is an increasing e-curve is multiplied by a reciprocal, that is to say a decreasing e-function.
  • the invention is not restricted to the exemplary embodiment described, but rather allows for a wide variety of variants with regard to the type and design of the paint spray gun and the bead spreading devices and the electronic circuit.
