Definitions
- Target shooting uses shooting targets with a number of concentric rings and a dark mirror in the middle. The distance between the bullet hole and the center of the mirror is determined by the eye.
- the object of the invention is to provide 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 consists in that a single disk or a disk belt passes through a first light barrier system, which generates a lo-center signal Lx and a mirror center signal Sx in the belt running direction x.
- the belt drive generates path pulse signals Ix that are 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 corresponding to the first light barrier system and arranged at right angles to this becomes rola Moved tiv to the shooting target transversely to its conveying direction 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 stored as a total value Y in a corresponding manner.
- the result is displayed as a ring number value, for example with a 10th division, and / or fed to a printer or a computer system.
- the respective central 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.
- FIG. 1 shows a side view of the evaluation device
- FIG. 2 shows a schematic top view of the device according to FIG. 1;
- FIG. 3 shows schematically the arrangement and function of one of two light barrier systems used
- Figure 4 illustrates one half in perspective a stationary light barrier system, which sits in front of the first pair of feed rollers;
- Figure 5 is a circuit diagram showing the various electronic components.
- 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 guide rods 42, 44 and 46, 48 fixed to the housing.
- a vertical drive shaft 50 and on the other side a deflecting shaft 52 rotatably mounted.
- 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 40, 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 includes 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 are approximately equal to twice the diameter of the bullet hole in the transverse spacing two extending over substantially the entire length of the plate 68
- Photo transistor lines 74, 76 arranged.
- a light emitting line 80 Arranged in the vertical plane of symmetry 78 to these two lines 74, 76 on the lower plate 70 is a light emitting line 80 consisting of a plurality of diodes or transistors lying close together.
- the receiver line 74 When the belt 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, is transmitted via a known comparator circuit generated for movement in the belt conveying direction.
- 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 cell-shaped but button-shaped and each consist of a light transmitter and an integrated light receiver. Since the window mirror is black and its external surroundings are white, the Stel receives 3 the reflection light barrier 86 more light than the light barrier 84, since more light is reflected from the white surface.
- both light barriers 84, 86 receive the same brightness if 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 reflection light barriers 88, 90, which corresponds to the first pair of light barriers 84, 86, the 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 seride beam on the top of the lower plate 70 of the light barrier system 1. Namely, when the shot hole 72 is in the bright area of the mirror edge area which its diffusely reflected light to the receivers of the reflection light barriers 84.86.
- the light barrier system 3 corresponds exactly to the system 1. However, it is fastened to the cross slide 38 by 90 °. After the mirror center signal Sx is generated when a shooting target 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 up 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 shooting disk. 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 deliver impulses Ix and iy continuously during engine running times.
- the path pulse signal Ix, 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.
- the y coordinate of these center distances is determined from the signals Sy, Ly and Iy 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 in the counter memory 8 accordingly.
- 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 10th division as the measurement result and sent to a printer 11 or an EDP system 12.
- the printer 11 can count be printer, which adds up the measurement results (ring number values) in the individual disks 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 predetermined response level is reached at one edge of the hole, the travel 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 Re arranged behind the pair of photo transistor lines 74, 80 in the direction of advance of the shooting disc 18 and the slide 38, respectively reflection light barriers 84.88 are omitted.
- the first mirror edge signal is recorded by the mirror edge sensor 86 or 90 when the light-dark boundary is passed when a preselected response level is reached, and the path pulse rate is counted until the same response level is determined by the same sensor 86 or 90 when it passes the dark light limit on the opposite mirror edge.
- the first mirror edge signal is a common start of counting for the pulse rates to determine 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.
