Definitions

  • the invention relates to an acceptance or return device for coins in a coin validator according to the preamble of claim 1.
  • DE-PS 38 30 920 It is known to arrange a coin gate designed as a lockable swivel flap in a coin channel.
  • the known device is connected upstream of the actual coin check in order to prevent the forwarding of coins for coin check in certain operating states, such as "not ready” or "sales process active".
  • the released position of the swivel flap it is pivoted by an impacting coin, as a result of which the coin arrives in an acceptance slot. If the coin is not accepted, the swivel flap is blocked by a lever.
  • the position of the lever is controlled by two electromagnets, which requires a relatively low power consumption.
  • the swivel flap is pivotally mounted at its upper end, while a lower angled end protrudes into the coin channel.
  • the swing flap is released by briefly energizing an electromagnet, whereby the locking lever releases the flap and the flap can rotate due to the coin weight.
  • the time of energization must be chosen so that the armature of the further electromagnet can fall from the end of the lever onto a shoulder.
  • the acceptance of the coin acceptance is retained until the locking lever turns to its rest position during a brief energization of the second electromagnet.
  • the invention is therefore based on the object of creating an acceptance or return device for coins in a coin validator which has a simple and compact design and for which not only a short-term, but also an overall very low power consumption is necessary for its operation.
  • the coin switch can be pivoted by an impacting coin when the coin switch is unlocked.
  • the coin switch is preferably rotatably mounted in a slot of a receptacle, the front section of the coin switch projecting into the coin channel being pivoted downward by an impacting coin and the coin entering an acceptance or return channel.
  • the coin switch is unlocked by the electromagnet actuating the locking lever, which can be formed by an anchor, whereupon the anchor locks the coin switch Position changes into a position unlocking the coin switch.
  • An upper, angled portion of the locking lever can extend through an opening in the coin gate so that it is substantially perpendicular to the coin gate.
  • the preferred essentially parallel arrangement of the coin branches to the longitudinal axis of the coin channel and the preferred mounting of the coin branches in the receptacle create a simple and compact device which is further characterized by a low power consumption, since the electromagnet only briefly (in pulses) ) and must tighten over a short distance to unlock the coin switch. As soon as the rotating movement of the coin switches has started due to an impacting coin, no further action of force by the electromagnet on the armature is necessary, since the coin switches automatically rotate back to their starting position due to their bearing and the locking lever or armature is returned to the locking position by means of a spring mechanism.
  • the acceptance and return device can be coupled with a coin checking system.
  • the test electronics of the coin validator can Activate the electromagnets of the device according to the invention in such a way that it briefly attracts the armature, whereupon the coin switch is unlocked and the impinging coin swivels the coin switch and reaches the acceptance channel.
  • the electromagnet is not energized, the coin gate remains locked, whereupon the counterfeit coin arrives in the return channel.
  • a particularly advantageous embodiment of the invention consists in rotatably mounting the coin diverter formed from flat material in a slot in a receptacle, which is also preferably made from flat material.
  • the coin gate is a kind of balance lever that can be held in the rest position by the weight of one balance arm, in which the other balance arm protrudes into the coin channel.
  • the locking lever interacts with the coin gate via an opening in the coin gate.
  • the locking lever which preferably forms the armature of the electromagnet, extends through an opening of the coin switch, wherein a bent portion of the locking lever engages the opening edge and causes the coin switch to pivot into the operating position or lock in the operating position . It therefore depends on the formation of the opening in the coin switch, in which position of the locking lever the coin switch is locked or unlocked.
  • a further embodiment of the invention proposes that the coin channel is widened in the area of the coin branches, preferably by a shoulder which lies opposite the opening through which the coin branches project into the channel. As a result, the thread holding the coin is tensioned, so that swiveling back of the coin branches is reliably prevented and appropriate detection and signaling can take place.
  • the acceptance and return device according to the invention can easily be installed in relatively small devices in which only low voltages and / or currents are permissible (e.g. battery devices, desk phones).
  • the smallest power consumption, at which the function of the device according to the invention is still guaranteed at approximately 75 mW.
  • the bearings of the coin branches and the anchor are designed so that the parts can be easily manufactured and absorb the sometimes considerable forces which are caused by the striking coins without damage.
  • a coin switch 10 of the acceptance or return device shown in FIGS. 2 to 4 consists of a front section 11, a central section 12 and a rear section 13.
  • the coin switch is inserted into a slot in a receptacle 20 such that the front section 11 the coin branch protrudes into a coin channel 21.
  • the rest position of the coin branches can be seen from FIG. 2, this position being defined by a section 22 of the coin branches which bears against the receptacle 20.
  • the rear section 13 of the coin switch is arranged at right angles to sections 11 and 12 and serves as a counterweight.
  • An opening 23 is provided in the central section 12 of the coin switch.
  • An anchor 30 acting as a locking lever consists of a central section 31, an upper, angled section 32 and a lower section 33, which is arranged at right angles to the central section 31 of the anchor.
  • the upper section 32 of the armature extends through the opening 23 of the middle section 12 of the coin switch 10.
  • the armature 30 is rotatably mounted in a yoke 40 which is connected to an electromagnet 41.
  • the lower section 33 of the armature which engages the receptacle 20, limits its movement, while an edge 42 on the receptacle ensures the position of the armature.
  • a leaf spring 43 which is fastened to the receptacle 20, engages on the lower section 33 of the armature 30.
  • the rest position of the coin switch 10 is shown in FIG. 1.
  • the coin switch is locked by the armature 30, which, according to FIG. 3, is in the position 50.
  • a tested coin 60 which is to be accepted by the coin validator and moves in the coin channel 21
  • falls on the coin diverter 10 part of the kinetic energy will cause the coin diverter to rotate, so that the coin can pass a coin acceptor .
  • the rotary movement of the coin diverter can only take place if the coin checking system sends a corresponding impulse to the electromagnet 41 so that it attracts the armature 30, ie the armature 30 is then in position 51 and the coin diverter 10 is unlocked.
  • the turning back of the coin branches is effected by the angled section 13 of the coin branches acting as a counterweight.
  • the kinematics of the section 13 acting as a counterweight can be matched to the mass of the coin hitting it by varying its length accordingly.
  • Fig. 5a and 5b show a switch section 12a with an opening 23a through which the armature 31a extends with a cranked section.
  • 5a shows the anchor position 51 according to FIG. 3, in which the switch 10 can pivot freely.
  • Fig. 5b the anchor position 50 is shown, in which a locking takes place so that the coin rolls into the channel 21b (Fig. 1).
  • 6a and 6b are the Conditions vice versa.
  • 6a shows the armature position 51, in which a locking takes place, so that when the armature is attracted by the electromagnet, the coin 60 also enters the channel 21b.
  • 6b shows the anchor in position 50, in which the switch is unlocked, a coin can thus pivot the switch in order to enter the channel 21a. It is up to the user of the coin validator which of the two channels 21a and 21b he wants to use as the acceptance or return channel.
  • the optional unlocking and locking can take place in the two positions of the armature.
  • the acceptance gate 10 of the acceptance and return device 1 has a flag 70 which interacts with a forked light barrier 71.
  • the section 11 of the coin switch 10 extends through an opening 72 through a wall of the coin channel 21, and the opposite wall has a shoulder 74, against which the section 11 rests in the rest position. If a coin 60 is now attached to a thread and a swiveling open of the coin switch 10 is enabled, a Thread 76 tensioned, as shown in Fig. 8, so that the switch 10 can not swing back into the rest position.
  • the flag 70 actuates the light barrier 70 so that it can emit a thread signal which is processed in a downstream evaluation logic, not shown.
