Definitions

  • the invention relates to a test device for round disks, preferably of the same dimensions, in which the disks run on a guide supporting them on the circumference and on at least one side along at least one gauge.
  • a test device for round disks preferably of the same dimensions, in which the disks run on a guide supporting them on the circumference and on at least one side along at least one gauge.
  • it means round or polygonal disks, round disks, possibly with a raised rim, embossed coins, washers or similar technical disks.
  • Test devices of this type are used to check coins or coin blanks in various processing stages for dimensional accuracy, in particular with regard to diameter, thickness, roundness and flatness, as well as completeness of the shape. So far, these tests have been carried out directly in front of or behind the machine performing the individual processing step, for example a coin press. Since such presses currently work with stroke rates of less than 1000 strokes per minute, the previously known test devices, with their mechanical gauges and calibres in particular, are still sufficient in terms of performance.
  • each individual machine must be provided with its own test device, which, due to the high precision with which the gauges must be manufactured, significantly increases the price of the machine. It would be beneficial here to be able to operate several presses together with just one test device. However, the performance of the known test devices is not sufficient for this. In addition, the test accuracy leaves something to be desired.
  • the object of the present invention is therefore to provide a test device with which a considerably higher throughput can be achieved.
  • This test device should be reliable, low-wear and easy to convert to other disc dimensions.
  • the guide is preceded by an inclined sliding plane, onto which the panes can be placed horizontally from above, and over which at least one collecting rail inclined relative to the horizontal runs into the guide at its lower end.
  • the invention has the advantage that a large amount can be picked up and processed by the test device, essentially disordered slices.
  • the coins slide under their own weight down the inclined plane and are caught by the inclined collecting rail from the vertical movement and diverted to the side. If the number of arriving disks increases so that the catch rail can no longer pick up all the disks and remove them to the side, the disks start to roll over and jump over the catch rail. they then fall back onto the inclined slide level and can be caught there by an additional rail, which may be fitted for these excess panes, and then also removed to the side.
  • panes which are also not caught by the second rail, then fall into an overflow channel at the lower end of the slide level, from which they are fed back onto the inclined slide level from above via a conveyor device.
  • the discs picked up by the collecting rail start to roll due to the lateral inclination of the collecting rails, which causes the high throughput of the test device according to the invention.
  • the slide plane is inclined between 10 ° and 70 ° with respect to the vertical, or the collecting rail between 10 ° and 60 ° with respect to the horizontal.
  • a particularly even throughput is achieved with an inclination of the sliding plane of approximately 25 ° and an inclination of the catch rail of approximately 30 °.
  • the collecting rail has a thickness that is smaller than the radius but larger than the thickness of the disks. In this way it can be achieved that many panes are gripped and those panes which tip over when they hit the collecting rail fall over the collecting rail and do not hinder the rapid rolling of the remaining panes.
  • the collecting rail can have a separating section at the lower end, which has a thickness less than or equal to the pane thickness. If two slices roll down the collecting rail directly next to one another, the separating section causes these two slices to be separated and only one continues to run on the collecting rail while the other falls away downwards.
  • the collecting rail is matched to the dimensions of the disks in terms of their thickness, it is expedient to attach them to the slide level in a detachable and interchangeable manner, or adjustable to the respective coin dimensions. This ensures that the device can be easily converted to round disks of various dimensions.
  • the catch rail can have cutouts on its side facing the sliding plane, so that dirt carried by the round disks can fall behind the rail and thus do not impair the smooth running of the round disks.
  • pneumatically controlled blowing nozzles are provided in the area of the collecting rails, which are controlled at intervals to remove the dirt that builds up.
  • the slice separated in the separating section then runs through a test station.
  • a diameter gauge according to the invention has two strips of light-sensitive elements which are arranged on one side of the disc plane essentially parallel to it in such a way that at least one of the strips runs essentially along the guide.
  • this diameter gauge according to the invention has a light source which is arranged on the opposite side of the disk plane and throws parallel light onto the light-sensitive elements. The round disks rolling along the guide cast a shadow on the light-sensitive elements, which generate corresponding signals that are processed by an evaluation unit.
  • one bar is parallel to the part of the guide which supports the disks on the circumference and the other is arranged approximately at right angles to the first bar.
  • the diameter can be calculated in a particularly simple manner from the end points of the shadow cast by the pane onto the strips of light-sensitive elements. But even if the strips of light-sensitive elements are parallel or at any angle to one another, the diameter of the disk passing by can be determined from the end points mentioned.
  • Either the light source can emit flashes of light or the light-sensitive elements record their signals only briefly; which prevents the shadow from smearing during the optical integration time due to the disk movement.
  • the height between the part of the guide which supports the disks on the circumference and the bar of photosensitive elements running parallel to this is less than 4/5 of the disk diameter. This ensures that discrete measured values are obtained without a grinding cut.
  • the gauge integrated in the test device is a thickness gauge, it can have at least one measuring system, which consists of a bar of optoelectronic, light-sensitive elements, which is arranged above or below the guide perpendicular to the plane of the pane, and a on the other side of the guide, a bar of several light sources arranged parallel to the first bar, which throw parallel light onto the photosensitive elements via imaging optics and an evaluation unit which processes the signals generated by the photosensitive elements. Since the parallel light bundles generated by these light sources are each angularly offset from one another, they radiate around the disk, which casts a shadow in each of the light bundles, the width of which is detected by the light-sensitive elements.
  • the measured width is enlarged compared to the actual width. Only the slightest measured width of the disc coincides with the actual. In this way, a wobbling movement of the disk to be measured can be compensated.
  • a bar with singular light-sensitive detectors a single continuous detector can be used, which works analog.
  • the detectors can also be arranged in areas, in particular in a polar coordinate system.
  • the parallel light bundles In the area of the lateral delimitation of the panes, the parallel light bundles must be able to reach the light-sensitive elements unhindered, apart from these panes themselves. For this it is necessary to provide suitable recesses in the slide level and the guide.
  • the thickness gauge can have at least two measuring systems arranged at an angle to one another.
  • the testing device in order that disks in which an incorrect dimension has been determined are sorted out, it is expedient for the testing device to have an ejection unit at the end of one or more gauges, the ejection unit in one embodiment according to the invention Is air nozzle, which is arranged in the region of the part of the guide supporting the disc on the side. A blast of air through this nozzle can push a disk past it from the running rail, so that it falls into a reject collection shaft assigned to the ejection unit.
  • the ejection can expediently also take place by means of electromagnets generating eddy current. Otherwise, the tour ends in a collecting shaft for "good" slices, from where the slices can be fed to a further processing step or to the final inspection or packaging.
  • the disks 4 slide down this slide level 6 until they meet a catch rail 7 which is arranged on the slide level 6 at a laterally inclined position.
  • the collecting rails 7, 10 In the case of the disks running along the collecting rails 7, 10, two disks (13) may run directly next to one another. So that this does not come in at the same time the gauges or calibres connected downstream of the collecting rail, the collecting rails 7, 10 have, at their lower end, singling sections 14 which have the thickness of a single disk.
  • the disks After the disks have been separated in the manner described, they roll or slide past a diameter gauge 16 and a thickness gauge 17 indicated only by the coordinate crosses for their sorting on a guide 15. Should it be determined in these teachings that the diameter or the thickness of the disc being tested does not correspond to the target values, then an air blast is imparted to the discs via air nozzles 18 which are installed in the slide plane 6 at the end of the gauges 16, 17 that they fall from the guide 15 into a committee collecting shaft 19. Otherwise, the disks run to the end of the guide 15 and can be fed there to the next processing stage or the final inspection, etc.
  • FIG. 3 shows how a light source 20 parallel light 21 on a disc 22 throws, which runs along a guide 23 in front of two strips of light-sensitive elements 24, 25. These strips 24, 25 are shown in more detail in FIG. 2.
  • the bar 24 runs at a constant distance ⁇ to the guide 23 and the bar 25 runs at a right angle to it at the point X ⁇ . Due to the shadow cast by the disc 22 onto the strips 24, 25, the points X0 and X1 as well as Y0 and Y1 result.
  • the position of the center point can be calculated directly from this: The center point can also be determined by a compensation calculation. The following applies Since it applies you get two equations for the unknown X M and Y M.
  • All four values r00 to r11 must match the specified radius of the disk up to predetermined tolerances, otherwise the disk 22 is blown by the air nozzle 26 from the guide 23 when the position X D is reached.
  • the strips 24 and 25 can either be arranged directly behind the panes 22 such that the panes 22 cast a shadow on the strips 24 and 25.
  • the disks 22 can be imaged on the strips 24 and 25 with the aid of a lens.
  • the strips of light-sensitive elements 24 and 25, which can be CCD strips, are controlled by a driver 27.
  • the signals of the strips 24, 25 generated by the parallel light 21 are then converted by an analog-digital converter 28 and fed to a computer with signal processor 29.
  • This computer 29 also contains an interface circuit 30, with which a light source driver 31 is controlled, which controls the light source 20.
  • the light source 20 emits flashes of light of such a length of time that the signal picked up by the CCD strips is not unduly blurred.
  • a programmable controller 32 is coupled to the computer with the signal processor and has a monitor 33 and a keyboard 34, via which it can be programmed.
  • the programmable controller 32 controls a valve driver 35 with which a valve 36 is to be opened, through which compressed air 37 is passed through the air nozzle 26, which functions in the manner described above.
  • FIG. 4b light which is emitted by the light 39 from a light source 44 which is adjacent to the light source 38 is inclined onto the pane 40 as parallel light. This results in a wider shadow 45 on the bar more sensitive to light Elements 43.
  • the disk 40 tumbles, it would not cast the thinnest shadow through the light source 38, as shown, but through the light source 44, so that the effective thickness of the disk can be determined even with a tumbling disk.
  • the shadow can be cast onto the bar of light-sensitive elements 43 either directly or via a lens.
  • FIG. 5 shows that several thickness measuring systems of the type just described can also be arranged at different angles ⁇ , ⁇ to the guide 41, so that the disk 40 is measured by several thickness measuring systems at the same time. If the disk is not within the required thickness tolerance, it is pushed into the reject collection shaft 19 by the guide 41 as already described for the diameter gauge.
  • the invention specifies a possibility of contactlessly testing a large number of disks or disk-like objects or of treating them in another way, as a result of which piece numbers can be achieved which were previously not possible.
