Definitions

  • a generic method and a device are known from DE-A-1 703 171. These have two orthogonal light barrier systems, each with 200 light transmitters and receivers arranged at the same distance from each other. The projectiles flying through interrupt the photoelectric light barriers and the corresponding coordinates are transmitted to a display arrangement via a memory arrangement and a query arrangement.
  • the object of the invention is to create a method and a device for automatic hit evaluation of shooting targets in order to avoid subjective measurement errors, to improve the evaluation accuracy and to reduce the evaluation time.
  • the invention basically consists in the fact that a single disk or a disk belt runs through a first light barrier system, which generates a hole center signal Lx and a mirror center signal Sx in the direction of belt travel x.
  • the belt drive generates path pulse signals Ix proportional to the belt feed. Only the path pulse rate that occurs between the generation of the signals Lx and Sx is passed through a pulse gate circuit.
  • the path pulse sum X is formed from the number of these path pulses.
  • a second light barrier system which corresponds to the first light barrier system and is arranged at right angles to the latter, is moved transversely to the conveying direction relative to the shooting target, and the path impulses in the direction y of this transverse movement between the formation of a hole center signal Ly and a mirror center signal Sy are added and as a total value Y saved.
  • the respective center signals are determined by sensing the opposite edge signals.
  • the evaluation accuracy is 10 times greater than that of manual evaluation and the evaluation time is only about 1 second.
  • the shooting target evaluation unit consists of a prismatic housing 14 with a tapering inlet gap 22 on the front and an outlet gap 16 on the opposite housing wall.
  • the roller 28 is driven directly by a drive motor 36 which is connected to a step pulse generator 2. Both rollers 24, 28 of the roller pairs carry gear wheels 31, 32 and are synchronized by a toothed belt 34.
  • the second light barrier system 3 ' is arranged on a cross-movable carriage 38, which consists of an upper plate 40 and a lower plate 42', both of which are displaceably guided independently of one another on housing-fixed guide rods 42, 44 and 46, 48, respectively.
  • a vertical drive shaft 50 is rotatably supported on one side and a deflection shaft 52 on the other side. Both shafts carry upper and lower gear wheels 54, 56.
  • the two upper gear wheels 54, 54 and the two lower gear wheels 56, 56 are each wrapped by a toothed belt 58 and 60, respectively.
  • the drive shaft 50 is connected directly to a drive motor 62, which also has a step pulse generator 4 (FIG. 5).
  • the motor 62 can be reversed.
  • Both toothed belts 58, 60 have driver pins 64, 66 which engage in corresponding bores in the plates 50, 42 ', so that the motor 62 can alternately reciprocate them in opposite directions across the feed path of the belt 18.
  • the light barrier system 1 contains an upper plate 68 and a lower plate 70, both of which are of the same size and extend across the disc band 18.
  • the length of the plates is at least equal to the diameter of the largest disc ring.
  • Both plates 68, 70 are at approximately the same distance from the plane of movement of the belt 18, which is approximately 2 to 5 times the diameter of a bullet hole 72.
  • On the underside of the top plate 68, at a transverse distance approximately equal to twice the diameter of the bullet hole, two photo transistor lines 74, 76 extending over essentially the entire length of the plate 68 are arranged.
  • a light emitting line 80 consisting of a plurality of diodes or transistors lying close together.
  • the receiver line 74 When the band 18 moves in the direction of the arrow 82, the receiver line 74 first receives light from the transmission line 80 through the shot hole 72 as soon as both receiver lines 74, 76 receive the same brightness, a signal Lx, the so-called punch center signal for movement in the belt conveying direction, is generated via a comparator circuit known per se.
  • a signal Sx is triggered in the light barrier system 1 when the center of the mirror 20 reaches the vertical plane 78 with the pane belt 18 moved forward.
  • two reflective light barriers 84, 86 are arranged on the underside of the top plate 68 - one behind the other in the conveying direction and at a distance approximately the same as the diameter of a disk mirror 20, which are not linear but button-shaped and each consist of a light transmitter and an integrated light receiver. Since the disk mirror is black and its outer surroundings are white, the reflection light barriers 86 receive more light than the light barrier 84 when the disk mirror 20 is in FIG. 3, since more light is reflected by the white surface.
  • both light barriers 84, 86 receive the same brightness when the mirror 20 is to the left of the position shown in FIG. 3.
  • the reception of the same brightness values in the light barriers 84, 86 is in turn processed in a comparator circuit to the mirror center signal Sx mentioned.
  • the two reflection light barriers 84, 86 could be arranged in the central vertical longitudinal plane of the belt conveyor track. However, it is better to use a second pair of retro-reflective sensors 88, 90, which corresponds to the first pair of light-barriers 84, 86, one pair of barriers being arranged on one side and the other pair on the other side of this vertical longitudinal center plane.
  • each of the four reflection light barriers 84-90 is assigned a phototransistor 92 and 94, respectively, in the extension of the light emission beam on the upper side of the lower plate 70 of the light barrier system 1.
  • the shot hole 72 lies in the bright area of the mirror edge region which its diffusely reflected light is intended to send back to the receivers of the reflection light barriers 84, 86, then a faulty mirror center signal can arise. This is avoided by the fact that light transmitted through a shot hole 72 in the reflection area from the light barriers 84, 86 reaches the receiver 92 or 92 underneath and thus generates a signal which suppresses the hole center signal of these two light barriers 84, 86 and on the mirror center signal Sx of the other pair of reflection light barriers 88, 90 operated free from the shot hole area of the mirror edge.
  • the light barrier system 3 corresponds exactly to the system 1. However, it is fastened to the cross slide 38 rotated by 90 °. After the mirror center signal Sx has been generated when a shooting disk mirror 20 passes through the light barrier system 1, the motor 36 is stopped at the moment in which, after counting the number of step pulses, the mirror center has approximately reached the central vertical transverse plane 96 of the cross slide 38. The motor 62 thus starts and moves the cross slide 38 perpendicular to the conveying direction of the belt 18 by an amount which is at least equal to the outer diameter of the target. In this light barrier system 3, the pane center signal Sy and the shot hole center signal Ly are generated analogously to the system 1. The two pulse generators 2 and 4 of the motors 36 and 62 continuously supply pulses Ix and ly during the motor running times.
  • the path pulse signal [x, the hole center signal Lx and the mirror center signal Sx are fed to a pulse gate circuit 5, with the aid of the signal pair Lx / Sx only the pulse rate which corresponds to the x coordinate between the hole center and the mirror center is passed through. Accordingly, the y coordinate of these center distances is determined from the signals Sy, Ly and ly in a gate circuit 6.
  • the transmitted pulse rates x are counted in a memory counter 7 and buffered.
  • the transmitted pulse rates y are processed accordingly in the counter memory 8.
  • the value r is therefore proportional to the distance between the center of the shot hole and the center of the mirror.
  • the r signal is processed by multiplication with an adjustable calibration factor and decoding in the circuit 10 to the ring number value, for example with a 10te1 division as the measurement result, and is sent to a printer 11 or a computer system 12.
  • the printer 11 can be a counter printer, which adds up the measurement results (ring number values) in the individual slices of the belt 19.
  • An alternative embodiment for the light barrier systems 1, 3 consists in that the phototransistor line 76 is omitted to determine the hole edge signals and the remaining phototransistor line 74 is aligned vertically with the light transmission line 80. If a given response level is reached at one edge of the hole, the path pulse rate of the disc belt or the slide is counted until the same response level is reached at the opposite edge of the hole. The center of the hole is determined by halving the path pulse rate. A corresponding procedure is advantageously used when determining the mirror center signal.
  • the pair of reflection light barriers 84, 88 arranged behind the pair of phototransistor lines 74, 80 in the feed direction of the shooting disk 18 or the slide 38 is omitted.
  • the first mirror edge signal is recorded by the mirror edge sensor 86 or 90 when the light-dark limit is passed when a preselected response level is reached, and the path pulse rate is counted until the same response level is passed when the dark light limit is passed the mirror edge is determined by the same sensor 86 or 90.
  • the first mirror edge signal is a common start of counting for the pulse rates for determining the difference between the mirror center and hole center coordinates.
  • the mirror edge sensor 86 or 90 must lie at a distance in front of the pair of hole sensors 74, 80 in the direction of movement of the disk or the slide 38. This distance is taken into account when forming the difference by means of a corresponding constant path pulse rate.
