Definitions

  • the invention relates to a method according to the preamble of claim 1 and to an apparatus for performing the method.
  • a device of this type which is intended exclusively for sorting coins and is known from DE-PS 35 18 268, the coins pass through a coin detection device which controls an ejector which acts laterally on the coins to be separated.
  • the ejector pushes the coin aside so that it slides off the support edge and tilts into the sorting opening.
  • the movement occurring transversely to the direction of conveyance causes the coin concerned to brake and results in the subsequent coins jamming.
  • the traffic jam hinders the continuous work flow and includes the risk of causing malfunctions.
  • the sudden movement of the ejector generates a not inconsiderable noise, which is also accompanied by increased stress and heavy wear.
  • the invention is therefore based on the object of creating, in addition to a method, a device which enables disc-shaped round objects to be discharged at a high conveying speed without jam.
  • the solution according to the invention allows the same means to separate objects which are too small in diameter or too thick.
  • Objects that are too small in diameter fall through the appropriately sized sorting opening.
  • Objects that are too thick cause the conveying means to be displaced from the conveying plane and thus a lateral deflection of the same, whereby the object that is too thick is pulled away from the support edge until it tilts into the sorting opening.
  • This process does not take place suddenly, as with an ejector, but extends a part of the way along the conveyor line, so that the excretion takes place "gently".
  • the funds are temporarily lifted off from the adjacent objects that are not intended to be removed so that these objects are not carried along laterally.
  • the continuous conveyance of the objects is not hindered by the removal of a "wrong" object, since there is no sudden braking. Therefore, a traffic jam is also excluded.
  • the continuous conveyance also ensures that there is practically no slippage between the objects to be conveyed and the conveyor belt due to the removal of individual objects. There is no increased stress and noise generation during excretion. As soon as an object has tipped into the sorting opening, it is accelerated downward by the restoring force of the deflected conveying means, so that the guideway is free again for subsequent objects.
  • the device according to claim 3 is based on the inventive idea of making the removal of non-conforming items dependent on an increase in the conveying means, which are deflected laterally in such a way that they convey the item to be removed into the sorting opening.
  • a swing-out arm causes the required lateral deflection as soon as it is displaced upwards.
  • an embodiment according to claim 6 appears advantageous since the spring not only accelerates the restoring force, but also accelerates the tilted object away from the guideway.
  • the lifting movement can be converted into a lateral deflection movement without a pivotable element.
  • a preferred embodiment according to claim 8 specifies how such objects are output on the basis of further criteria are to be separated, the thickness of which does not exceed the permissible thickness.
  • An embodiment according to claim 9 is used to remove all objects which are too large in diameter and which, when conveyed along the guideway, run on one side onto the fixed ramp and thereby cause the corresponding deflection of the conveying means.
  • Such an embodiment makes it possible for objects which are too small or too large to be separated out through the same sorting opening without additional control means, while the objects which are not to be separated cross the sorting opening lying on the support edges.
  • the deflecting element can be moved into the guideway depending on any criteria, so that, for example, objects whose dimensions are not outside the permissible limits can also be removed.
  • the deflecting element is a pivotable ramp to achieve a relatively gentle deflecting movement.
  • the scanning and the elimination take place in spaced-apart stations. It is possible, for example, to scan the alloy of the individual objects and to make the excretion dependent on a non-conforming alloy.
  • the deflecting element has no moving parts.
  • the device can be adapted to objects with different diameters.
  • Fig. 1 shows a device in side view, which in the basic version in addition to the excretion of coins that are too small in diameter, in particular for exiting from coins that are too thick.
  • a conveyor 12 endless conveyor belt 12 'wraps around two rotating pulleys 46 and 46' in the direction of the arrow.
  • the lower run 12 '' of the conveyor belt 12 engages by static friction from above on a coin 10 which is conveyed in a conveyor plane 20 along a guide path 18.
  • Two spring-loaded pressure rollers 48 ensure that the lower run 12 '' of the conveyor belt 12 'rests on the coins 10 to be conveyed over the entire conveying path.
  • FIG. 1 In order to increase the clarity, only one coin 10 is shown in FIG. 1. However, since it is a high-performance device, coin after coin is lined up in normal operation.
  • a sorting opening 14 is located in the bottom 52 of the guideway 18.
  • FIG. 2 From the top view according to FIG. 2 it can be seen how the coin 10 ⁇ which is not intended to be discharged is conveyed over the sorting opening 14. Since the conveyor belt 12 'offset from the center engages on the coin 10', this lies on one side during the conveyance on a guide rail 16. There is a narrow support edge 22 between the guide rail 16 and the sorting opening 14. The coin 10 ⁇ shown is so large in diameter that it just spans the sorting opening 14. It can therefore be deduced from the illustration that a smaller diameter the guide rail 16 falling coin falls into the sorting opening 14. From the two pulleys 46 and 46 ', the first pulley 46 is driven by a motor 54.
  • pivot axis 50 is laterally offset with respect to the guide roller 28.
  • the pivot axis 50 is located on a bracket 58 arranged on a wall 56.
  • the arm 26 and thus the guide roller 28 are up to a stop 36 under the action of a tension spring 30, so that the guide roller 28 on the lower run 12 'of the conveyor belt 12' is present.
  • Fig. 4 it is shown that the guide roller 28 and thus the lower run 12 '' of the conveyor belt 12 'is deflected towards the opposite side of the guide rail 16 when the lower run 12' 'is raised, for example, by a too thick coin. Due to the deflection, the coin 10 'is pulled laterally so that it slips off the support edge 22 and is tipped into the sorting opening 14.
  • the guide roller 28 endeavors to return to its normal position according to FIG. 3.
  • the tilted coin 10 ' is accelerated in the direction of arrow 60, so that the lower run 12' 'comes to rest on the other coins.
  • the deflection element 24, which has the guide roller, fulfills both functions, namely the detection of a coin that is too thick and the removal of the coin.
  • a conveyor belt deflector 42 with an inclined fixed deflection surface 42 ' is shown as the deflection element 24'. Viewed in the longitudinal direction of the conveyor track, the deflecting surface 42 'runs in an arc shape in order to achieve a gentle deflection of the lower run 12''.
  • the excess of a coin 10 ' is eliminated by the lower strand 12''being raised by the coin 10' and being deflected by the deflecting surface 42 '.
  • the coin to be separated 10 ' is pulled away from the support edge 22 so that it tilts into the sorting opening 14.
  • the embodiment according to FIG. 7 has as a deflecting element 24 '' a stationary conical deflecting roller 32.
  • the function of this deflection roller corresponds essentially to that of the deflection surface 42 '.
  • Both the conveyor belt deflector 42 according to FIG. 6 and a bearing pin 62 carrying the conical deflection roller 32 are fastened to the vertical wall 56.
  • a normal thickness coin 10' is shown in both Figures 6 and 7.
  • the sorting openings 14 are each arranged in a base plate 64.
  • the device shown in a plan view in FIG. 8 differs from the devices described so far in that on the guideway 18, opposite the lateral guide rail 16, in the conveying direction in front of or next to the sorting opening 14, a reject element 34 which raises the coins to be sorted out on one side in the form a ramp 44 is arranged.
  • the run-up ramp 44 is formed on a slide 66 which has a second support edge 68 opposite the guide rail 16.
  • the slider 66 is adjustable after loosening a wing screw 70.
  • the slide 66 is connected to two guide rods 74, each guided in a slide guide 72.
  • the slide 66 opposite lying, the guide rods 74 are connected to a bar 76 into which the wing screw 70 is screwed and can be displaced in an elongated hole 78 arranged in the base plate 64.
  • FIG. 9 shows a longitudinal section IX-IX according to FIG. 8.
  • FIG. 10 shows a cross section XX according to FIG. 8. From FIG. 10 it can be seen in particular that the adjusting elements 72, 74 and 76 are for the Slide 66 are located below the base plate 64. Furthermore, it can be clearly seen that the width of the sorting opening 14 can be adjusted with the slide 66.
  • the arrangement of the guide roller 28 corresponds to the explanations given for FIGS. 1 to 5.
  • FIGS. 11 to 14 show the same device as FIGS. 8 to 10.
  • FIGS. 11 and 12 show how a coin that is too small in diameter falls directly into the sorting opening 14.
  • FIGS. 13 and 14 it is shown in sequences how a coin 10 'which is too large in diameter runs onto the run-up ramp 44 serving as a deflecting element 34, thereby causing the guide roller 28 to be raised and deflected, to slide off the support edge 22 and into the sorting opening 14 is tipped over, the spring-loaded guide roller 28 helping.
  • Figures 15 to 19 show a device for separating non-compliant coins, regardless of their diameter and thickness. 15 and 16 it is Obviously, that serves as a deflecting element 24 '', a conical deflecting roller 32, as already explained for FIG. 7.
  • the remaining elements arranged above the base plate 64 essentially correspond to an embodiment according to FIGS. 1 and 2.
  • the electromagnet 84 is operated in dependence on the previously scanned properties of the conveyed coins when the coin 10 just passed was recognized as incorrect and determined to be eliminated .
  • the electromagnet 84 is connected to the aforementioned control circuit via connecting lines 86, has a plunger 88 and a return spring 90 for actuating the ramp ramp 38.
  • the electromagnet 84 is connected to the base plate 64 by means of a holder 92.
  • the run-up ramp 38 which can be actuated by the magnet 84, can be pivoted about a pivot axis 94.
  • a stop 96 formed by the holder 92 serves to limit the two end positions of the swivel path.
  • the mode of operation of the pivotable ramp ramp 38 can be seen from FIGS. 17 and 18. 17, the coin 10 can cross the sorting opening 14 unhindered. However, if the ramp ramp 38 is pivoted into the guideway according to FIG. 18, while the coin 10 'is immediately above it, the coin 10' is pulled away by the interaction of the deflection roller 32 with the lower run 12 '' of the conveyor belt 12 'from the support edge 22 and tipped into the sorting opening 14.
  • 17 and 18 show the guideway in cross section, the circled figures next to it show the respective position of the ramp 38 in a side view. 17, the upper surface of the ramp 38 is flush with the guideway 18.
  • the arrows below the ramp 38 each indicate the direction of actuation. 17, the direction of actuation is indicated by the restoring force of the spring 90. 18 is the direction of actuation by the magnet 84.
  • the coins are conveyed along the guideway 18 at a relatively high speed. It is therefore necessary that the pivoting-in duration of the ramp 38 according to FIG. 18 is of the order of milliseconds.
  • the 19 shows the control circuit 98 already mentioned, to which the signals from the sensors 40 are fed via the lines 82.
  • the electromagnet 84 is controlled via the line 86.
  • the sensors 40 can, for example, sense the inductance of the coins conveyed past, which allows a conclusion to be drawn about their alloy.
