Definitions

  • the invention relates to a device for checking the magnetic property of a coin in self-cashing devices, for example for releasing and displaying a parking time in a parking meter, and for controlling a coin diameter test process as a function of an entered coin which remains statically on a coin support.
  • This method is based on the use of a sensitive coin scale and usually also requires a longer coin transport path into which a coin scale is arranged and good and bad coins are diverted via two separate channels.
  • the use of the coin scale in the parking meter has not proven itself due to the harsh environmental conditions, since selection by weighing does not guarantee satisfactory functioning.
  • the disruptive influences on a coin scale can be explained by the location of the parking meters, which are usually located on the side of the road or in open spaces, where extreme conditions such as cold, wet, and contamination of the sensitive technology of a coin scale are hard on.
  • German utility model 17 45 46o a simple magnetic coin check has become known which provides a magnet in the coin channel which deflects a coin which can be influenced by a magnetic force field in a certain direction.
  • a permanent magnet in the form of a circular disk is proposed which is magnetized in such a way that the magnetic lines of force run outside around each half disk.
  • a magnetically influenceable coin falls through its own weight through the field line zone of the magnetic disk and rolls with the outer surface due to the effective attraction force on the magnetic disk.
  • a real coin is deflected into a coin channel, which is used only to trigger the parking meter functions via a diameter test.
  • a coin that cannot be influenced magnetically falls vertically into a collecting container without any deflection by the magnetic disk.
  • a further magnetic coin check is known, through which a rotatably mounted locking bolt in its rest position with one end blocks a stylus on a double lever for the diameter scanning and time release, with the other end, which carries a magnet , extends into the coin transport path.
  • the magnetic test lever interacts directly with a pivotable diameter sensing element via a swivel arm, so that one diameter sensing element (feeler pin) and thus the double lever is held in a locked position.
  • the magnetic arm of the locking lever protrudes into the coin entry slot, leading the diameter check.
  • the diameter sensing element is part of the double lever, which in turn blocks or releases the sensing element for the setting of a time control device.
  • This double lever must, if you want one at all Trigger time setting, always be released before each diameter test. This release can only ever be given by an iron-containing object.
  • the entrainment of the locking lever caused solely by the line of force does not guarantee absolute functional reliability.
  • the frictional relationships between the locking lever and the double lever allow many functional uncertainties. The separation of a ferromagnetic coin against a usable coin that does not contain iron cannot be carried out with this device, since the double lever for releasing the time setting can only be freely controlled by the blocking lever using coins made of ferromagnetic substances.
  • a cross-sectional checking zone is provided in the coin transport channel.
  • two magnets are arranged on a fixed coin channel wall, which attract a coin that is guided past and can be influenced magnetically. Due to the lateral movement of the coin, a spring-loaded probe lever immersed in the test zone is deflected into a position that enables the time setting.
  • DE-OS 29 49 658 a coin checking device for parking meters with a coin transport system has become known. Based on the thickness of the usable coin is at this device, the coin transport channel widened in cross section, and at the same time fixed magnets are arranged in a side wall, which cause a ferromagnetic coin to be moved laterally.
  • laterally offset coin support tracks are provided in the area of the test zone and are arranged at different heights with respect to the coin support base. A magnetically influenceable coin is deflected laterally by the magnetic effect, reaches the corresponding coin support base, which differs in height from the coin support base for non-ferrous coins.
  • This device is actually only suitable for distinguishing coins of the same diameter, but made of magnetically different material, the coins also being inevitably guided through the test zone by a transport system.
  • the object of the invention is to provide a simple device for testing the magnetic property of a coin after its input into a coin test organ in a self-collecting device and for triggering the evaluation of a usable coin or collection as counterfeit coin.
  • the object of the invention is to provide an anchor designed as a double-armed rocker on one side wall of a coin guide shaft, one arm of which is provided with a permanent magnet and with the latter dips into the area of a coin inserted into the coin guide shaft and resting on the coin support, the other arm has a side locking bracket that engages and disengages a test segment for diameter testing is controllable.
  • the device essentially consists of an armature which can be controlled in two functional positions and has a permanent magnet as an effective magnetic field.
  • the armature is designed as a double-armed rocker over the cantilever arms as a swivel bearing axis and engages with a locking bracket directly in the movement path of the test segment, which is only set in motion as a diameter sensing element after a coin has been entered and the rotary toggle is actuated.
  • the coin falls onto a coin support in the test area after it has been entered and remains there in a defined position on prismatic supports.
  • a permanent magnet on the rocker in the area of the stationary coin reacts immediately due to the nature of the coin material, ie it is attracted to an iron-containing coin or remains in the starting base for material that cannot be influenced magnetically.
  • the locking bracket on the rocker can be functionally adjusted to the effectiveness of the test segment so that the latter carries out the diameter test or not. It is of fundamental importance that the function of the rocker in cooperation with the test segment can be set so that, depending on the type of coin material approved for a device, coins consisting of non-approved material are excreted. This means that if iron-containing coins are approved for evaluation, all coins that cannot be influenced magnetically are eliminated with this device.
  • any ferrous object from the start in front of each diameter examination are excreted when magnetically influenceable M zen UEN to an apparatus for.
  • plastic tokens are determined as usable. An effective decision is guaranteed in the simplest way that the permanent magnet responds depending on the test material and the locking bracket from the locking position to the release position, or the locking bracket from the release position in the Lock position controls. The test functions cannot overlap, as a diameter test is only triggered much later when the rotary knob is actuated.
  • FIG. 1 shows a side view of a parking mechanism with the housing parts removed.
  • all devices for coin acceptance and their evaluation up to the setting of a corresponding parking time specification are stored between a front plate 1 and a rear plate 2.
  • the front board 1 is the side facing the user.
  • a rotary toggle 3 is arranged on this side, which is arranged on a shaft 4 rotatably mounted in the front plate 1 and rotates with the latter is firmly connected.
  • the rotary knob 3 is used for manually actuating the parking meter to a preset parking time after a usable coin 5 has previously been entered.
  • a lockable coin input device 6 designed as a compact assembly is provided, which serves to insert coins 5 of all common diameters, but prevents other unsuitable objects from being inserted which block the clockwork or render it inoperable.
  • a preset time display mechanism 7 can be set, which marks a parking time preset by adjusting a rotatable time slice 8 on a time scale 9.
  • a time drive 10 is attached with two screws 11 as a separate assembly, which can be easily replaced.
  • the front plate 1 and the rear plate 2 are assembled with three self-tapping screws 12 via spacing pillars 13, 14 and 15, 16 cast onto the plates 1, 2, respectively.
  • the time scale 9 is inserted between the two spacing pillars 13, 14 before the two upper screws 12 are tightened.
  • a coin guide channel 18 is provided behind the coin input device 6 and runs obliquely downward and integrally formed on the front plate 1.
  • the coin input device 6 is connected in a geared manner to a locking segment 26, which is rotatably supported on the front plate 1 and has a positive drive connection to the rotary knob 3. Only in the basic position of the rotary knob 3 is the coin input device 6 unlocked, so that a coin 5 can only be inserted into the device in this initial state.
  • the Münzleitkanal 18 ends in a profile similar moderately M ünz operationsschacht 19 which is integrally formed on the rear board. 2
  • the coin guide channel 18 and the coin guide shaft 19 form the coin checking zone in which a coin 5 initially rests on a prism-shaped support 20, 21 for the purpose of diameter testing.
  • the one in one Th angles arranged to each other 2 0 , 21 are part of a pivotable coin bar 22 which is mounted between the front plate 1 and the rear plate 2.
  • the coin bar 22 occupies two functional positions. In the starting position, the coin bar 22 is pivoted in against the action of a tension spring 33, so that the two supports 20, 21 close the downwardly open coin guide channel 18 and the coin guide shaft 19.
  • the coin bar 22 is in geared connection to a control disk 24 on a shaft 25 of a coin checking device 17.
  • the control disk 24 is supported by a driver 27 on the closing segment 26, which is connected via a geared connection when the rotary knob 3 is actuated in the counterclockwise direction according to FIG . 2 is driven, taken.
  • the control disk 24 drives a torsion-sprung clutch bushing 28, which is rotatably supported on the shaft 25,
  • test segment 29 arranged coaxially rotatable on the shaft 25.
  • the test segment 29 is designed as a double lever, in which a sensing element 30 is provided on one arm and a toothed segment 31 is provided on the second arm. According to FIG. 2, the test segment is pivoted upon actuation of the D rehknebels 3 from the starting position clockwise 29th The sensing element 30 comes into contact with the circumference of a coin 5 accommodated in the prismatic support 2 0 , 21 of the coin bar 22. The overlap to be traversed by the control disk 24 is received by the torsion spring-loaded coupling bush 28.
  • the setting position of the sensing element 30 bearing on the circumference of a coin 5 is transmitted to a toothed wheel 32 on a test disk 33 via the toothed segment 31 for evaluation. Doing so the test disk 33 is set against the force of a return spring 34 in a defined, lockable position. Ünz phenomenon for the phase of M, which is up to and including the appropriate setting of the Prfifprint 33 in a latched position, the coin 5 remains in the test position on the supports 2o, 21 of the Münzriegels 22. This is ensured by the control disc 24 a peripheral Has curve element 35, which presses against the coin bar 22 until that the checking process is completed. Thereafter, the control disk 24 is driven in the opposite direction and releases the coin bar 22 through the falling region of the cam element 35, which swings out following the action of the tension spring 23 and allows the coin 5 to fall freely downward.
  • one of the test uses the magnetic properties of the - coin material. Such a check is absolutely indispensable if, for example, play money is in circulation in the form of plastic coins that have been accurately reproduced. A distinction can then only be made by specifying the material. A test using a magnetic force field is particularly suitable for this. Since most coins are made of ferrous material, they also react to exposure to a magnetic field. In order to fundamentally make a separation that is completely independent of the other test criteria (diameter, thickness), the test for ferromagnetic properties of the coin 5 and its triggering control effect is included as the first test phase in the coin test procedure. This means that excretion takes place when the material properties prove unsuitable. Suitable phase of testing a coin on ferromagnetic characteristic of the torque is directly viewed, in which the coin 5 to the input on the supports 2 0, 21 and arrives temporarily motionless by the Münzriegel 22 in Münz Resultsschacht 19 is held.
  • the McMetracher 37 armature 38 to a side wall 36, of which one arm is provided with a permanent magnet 39 and with the latter in the area of an input to the Münz Operationssschacht 19 on which Münzauflage 2 0 , 21 lying on the coin 5, the other arm has a lateral locking bracket 4o, which can be controlled in and out of engagement with a test segment 29 for diameter testing.
  • the rocker 37 is equipped with a cantilever arm 41, 42 for pivoting movement, by means of which the rocker 37 is hooked into hook-shaped bracket 43 on the side wall 36 of the coin guide shaft 19.
  • the rocker 37 can be controlled in two defined functional positions.
  • the position designated as the starting position is ensured by the arrangement of a compression spring 44 between the rocker 37 and the side wall 36 of the coin guide shaft 19 and an adjustable adjusting screw 45 for determining the starting position of the rocker 37.
  • the setting of the rocker 37 in the end position is determined by the support thereof on the side wall 36 due to the tensile force effect of the permanent magnet 39 when on the M ünzauflage 20/21 existing ferromagnetic coin 5.
  • the initial position of the rocker 37 is adjustable by means of the adjusting screw 45, such that the locking clip is always 4o in front of a locking lug 46 on the test segment 29 provides and blocks the pivoting of the test segment 29, and a free control of the test segment 29 takes place in that the armature 38 is attracted by a ferromagnetic coin 5 and the locking bracket 40 is controlled from its locked position.
  • the magnetically influenceable coin 5 is eliminated and all other coins 5 or tokens made of non-ferrous material or plastic pass through the first test criterion as usable.
  • the starting position of the rocker 37 can be adjusted by means of the adjusting screw 45, so that the locking bracket 4o in the initial position of the rocker 37 can always be immersed in a slot-shaped recess 47 on the test segment 29 and the latter for a pivoting movement Diameter test frees up, when you enter a ferromagnetic coin 5 immediately removes the exemption and controls the locking bracket 40 in the effective area of a further locking lug 48 on the test segment 29.
  • the test segment 29 cannot lower itself onto a coin 5, there is no diameter test, and after that no time can be set.
  • a hole 49 is provided on one side, which creates a collet effect, due to which the installation dimension for the immersion depth of the cylindrical permanent magnet 39 can be changed and thus a certain air gap to the position of the coin 5 is adjustable.
  • the air gap is required so that the magnetically influenceable coin 5 can fall freely after the test after being released by the coin bar 22 and is not held by the magnetic force field and is additionally attached to the angular end face of the permanent magnet 39 by the coinage on a coin .
  • the rocker 37 has a control finger 50 which cooperates with a scraper bracket 51 on the pivotable coin bar 22, so that when the coin bar 22 is pivoted, the rocker 37 is inevitably pivoted into the starting position, in which the coin 5 is unhindered by the magnetic field in a collecting container can fall. Due to the inevitable f i ge control of the rocker 37 in the starting position, the force field effect tears off largely, and there is a guarantee that the coin does not get caught due to the large air gap.
  • the stripper bracket 51 is screwed to the coin bar 22 by means of a screw 52.
