Definitions

• a coin sorter apparatus and use of such apparatus are provided.
• the invention relates to a coin sorter apparatus according to the precharacterizing clause of Patent Claim 1.
• the invention applies but is not limiting to the coin sorter apparatus manufacturing industry.
• the invention also relates to the use of such a coin sorter apparatus.
• Coin sorter apparatuses are used in, inter alia, systems for automatic coin handling.
• the coin sorter apparatuses are used in, for example, coin changers or other cash systems. Examples of the area of application of such cash systems can be found within trade and in stores . These cash systems provide safer and more rapid coin handling for both personnel responsible for cash and customers; see, for example, US 5 562 536 which discloses a coin sorter construction.
• One object of the present invention is to eliminate said disadvantages of known constructions .
• Another object of the invention is to produce a coin sorter apparatus which sorts coins according to denomination, at the same time as the transport distance for the coins is shorter.
• a further object of the invention is to produce a coin sorter apparatus which sorts coins according to size in order to facilitate transport to, for example, a bank.
• the coin sorter apparatus is characterized by the features indicated in the characterizing part of Patent Claim 1.
• the distribution means comprises a portion designed for receiving coins standing vertically on their edge by means of a guide means arranged on the transport device.
• the aperture of the distribution means adapted for distribution of the coins to at least one sorting unit, consists of a slot designed with steps. In this way, a number of coins can be accommodated side by side at the same time as every coin is transported directly to the respective sorting unit at the moment of distribution itself.
• the transport device is suitably coupled to a drive unit in order to bring about transport of the coins along a plane extending parallel to the main extent of the distribution means and along said slot.
• the drive unit such as an electric motor, can advantageously be positioned in the transport device, which arrangement requires little space.
• the transport device is preferably designed with a number of compartments, arranged one after another and without a bottom, the main extent of the compartments extending transversely to the longitudinal direction of the slot and each compartment being designed so as to be capable of accommodating at least one coin. In this way, in each compartment, every coin can rest vertically on its edge against the distribution means before the coin is distributed.
• the design of the transport device can be less bulky than known art at the same time as a number of coins for sorting and transport can be accommodated in the transport device.
• coin sorter apparatuses are suitably designed with a coin insertion slot for receiving coins edge first, the guidance of the coin is carried out directly into a position in which it can rest upright with its edge directly against the distribution means . An additional guide for bringing about sorting of the coin is no longer necessary.
• the guide means is advantageously driven in a direction along the slot designed with steps in such a manner that, in a first position, the coins come to lie at a first step with a width which is greater than the diameter of the coin with the smallest diameter but smaller than the diameter of the other coins.
• the coin with the smallest diameter thus falls into a first sorting unit, and other coins are transported onward for sorting.
• a sensor is preferably positioned at the coin insertion slot in order to sense every coin dropped down.
• the computer which is connected to a computer, senses that a coin has passed down to the distribution means, the computer gives a signal to a control unit to drive the transport device a distance corresponding to the spacing between two adjacent compartments.
• a second step has a width which is greater than the diameter of the coin with the next smallest diameter but smaller than the diameter of other coins except the coins with the smallest and the next smallest diameter. In this way, coins with the next smallest diameter can be sorted into a second sorting unit .
• subsequent steps have a width which becomes greater for each step, the width of the step being adapted according to the respective diameter of the coin to be sorted.
• the width of the step being adapted according to the respective diameter of the coin to be sorted.
• all sizes of coin in a currency can be sorted.
• coins can also be sorted according to denomination and each sorting unit receives a specific denomination.
• the handling of the sorting units for, for example, personnel responsible for cash is also simplified in comparison with known art.
• the present invention also means that coins can be sorted according to size, that is to say if there are a number of sizes of coin for a denomination, which facilitates transport to, for example, a bank.
• the distribution means is preferably a plane panel, in which the slot designed with steps in the panel describes a circular line.
• This solution means that the transport device can be designed as a carousel, the compartments of the carousel being guided along the slot designed with steps during operation for sorting the coins .
• the slot designed with steps suitably has its main extent along an essentially straight line.
• the coins can be transported over sorting units positioned in a row.
• this embodiment can facilitate handling of the sorted coins by, for example, personnel responsible for cash.
• the apparatus can, for example, be designed in such a manner that the personnel responsible for cash can reach the sorting units from one side.
• the transport device advantageously consists of a chain with lugs arranged at a spacing from one another, the main extent of the lugs extending transversely to the longitudinal direction of the slot so as to form said compartments .
• the transport device can thus be designed so as to be capable of being driven along the desired curvature of a slot designed with steps.
• the sorting unit preferably comprises at least one collecting container arranged removably under each step.
• the collecting container is removable, personnel responsible for cash, for example, can take the sorted coins out in a simple manner.
• Other arrangements for the transport of sorted coins instead of collecting containers can of course be arranged together with the sorting unit.
• the number of steps is preferably the same as the number of sizes of diameter of the coins to be sorted.
• the number of collecting containers and the number of steps is suitably eight. In this way, the coin sorter apparatus is adapted to the euro.
• Said compartments are preferably designed with such a width, seen in the main direction of the slot, that at least two coins can be accommodated side by side with the flat sides towards one another. In this way, coins of thinner thickness can be accommodated in one and the same compartment.
• the computer is set so as not to advance a compartment when a second sensor senses the thickness of coins which are so thin that two coins are accommodated in the same compartment. In this way, space can be saved, the apparatus being less bulky than known constructions for coin sorting.
• the slot is suitably continuous for sorting all the coins in a currency. In this way, each coin can be guided along the slot and at the same time stand vertically on its edge at the guide means of the transport device.
