Abstract

Coins pass through a channel whose length edge runs at an angle to the vertical and has a pushout spring at passage opening fixed to the edge, its object is to bring the coin to the edge. In the passage opening the distance of the feeding edge from the opposite edge is greater than the diameter of the coin for rejection and smaller than the correct coin. The width is only slightly smaller than the opening to ensure passage of a coin through opening weighing and pushout spring are provided. The part which carries the passage opening and cover plate is swung away by a pusher which is operated by the dispensing mechanism.

"Sales device with a coin checking device ¹

The invention relates to a sales device, in particular for Sale of newspapers and magazines, with one device for checking the diameter of the inserted coins and for rejecting false coins, whereby the coins pass through a coin channel and one of the channels on the flat side of the coin adjacent coin channel walls is provided with a preferably elongated passage opening, with precautions being taken are to press the passing coins against the passage opening and to distinguish them according to their diameter, as well as on the side facing away from the coin channel Passage opening is an ejection channel leading to the return of money and the receiving width of the coin slot Diameter of the largest applicable coin. Coin checking devices of this type are known in various designs that are relatively complicated and expensive. In particular, there is the problem of proper passage of coins too small in diameter through the opening too

without making the construction too expensive. Above all was with the well-known institutions it was not properly ensured that such coins were also reliably distinguished, their diameter only differ from each other by very small amounts.

The object of the invention is therefore with a Although the simplest possible device to be able to distinguish such coins from one another, their diameter are almost the same.

In order to achieve this object, according to the invention, in the first place Line provided that a longitudinal edge of the coin channel in the area of the passage opening at an angle to the vertical runs and there forms a guide edge for the coin and that a pressure spring connected upstream of the passage opening is provided, which brings the coin to rest on the leading edge. This ensures that the Coin channel inserted coin slides properly along the leading edge, so that for the diameter check by means of the passage opening is given a reference edge on which the coin always rests. Because the distance this reference edge from the opposite edge of the passage opening forms the criterion for whether a Coin is still applicable, or has to be eliminated because the diameter is too small, you can use it also relatively small differences in diameter can be safely recorded. Tests have shown that even 2-pfennig pieces of 50-pfennig

Pieces can be separated, although the diameter of a 2-pfennig piece is only 0.7 mm less than that Diameter of a 50-pfennig piece. On the other hand would the The coin channel run vertically in the direction in which the coin falls and so that the leadership could also have this direction, so such a secure investment of the coin would not be guaranteed and thus the exact diameter check is no longer given. As explained, the pressure spring ensures that the coin rests securely on the leading edge. Besides that the dimensioning of the coin slot ensures that coins that are too large are eliminated from the start will.

Further advantages and features of the invention are the dependent claims, as well as that described below and in Embodiment according to the invention shown in the drawing refer to. In the drawing shows?

In the housing 1 of the coin validator is the coin channel 2, which is not accessible to the buyer via an outlet 3 Coin collecting container leads. The receiving width b of the coin channel 2, or. of the coin slot is chosen so that the applicable coins, in this example 10-pfennig and 50-pfennig coins, and thus all coins with a smaller diameter, can not be imported but coins whose diameter is larger than the diameter of a 10-pfennig or 50-pfennig piece.

In the course of the coin channel, an opening 4 for the passage of coins of small diameter is provided in a side wall adjacent to a flat coin side. For the sake of clarity, the area of this opening is shown hatched in FIG. 1. The passage opening is ^{delimited by the edges 4 1} , 4 "and the part of the coin channel located in its area is delimited by the edges 2 ', 2". The edge 2 'forms the explained leading edge. Its distance C from the opposite edge 4 ″ of the opening 4 is selected so that it is smaller than the diameter of the applicable coins (in this example 10 and 50 pfennig pieces), but larger than the diameter of the coins to be ejected (in the present case Example one-pfennig, two-pfennig and five-pfennig pieces). For the reasons explained in more detail below, it is recommended that the width B of the opening 4 is only slightly smaller than the distance C between the edges 2 'and 4 ".

The leading edge 2 'runs at an angle to the vertical or the direction of fall, so that the coins passing through the coin channel according to the arrows are securely in contact with it. For this purpose also serves ^v a pressure spring 7 which the coins against the edge 2 ¹ presses "The compression spring 7 is fixed 2" of the Münzkanales in the edge and at a location that lies before the passage opening. 4

The passage of the coins through the opening 4 can either by a corresponding inclination due to their gravity or by means of a spring known per se 5 take place. The direction of travel of the coins is shown in the figures 1 and 2 entered with the arrow A.

The opening 4 can be formed by a guide plate 8 inserted into the coin channel wall, the contours of which are shown in FIG Fig. 1 are shown in dashed lines. The baffle 8 is according to this preferred embodiment in the about the axis 9 laterally pivotable wall 10 of the Münzprüfeinrichtung attached. The cutout 11 located in this wall for receiving smaller coins leads over the exit 12 to the coin return accessible to the buyer.

The coin inserted at 13 will, provided its diameter is not too large, through the coin channel 2 in the area of the Passage opening out. As explained, a force of gravity or the spring 5 then causes a Pressing the coin against opening 4 or * against a contact surface, which is formed by the baffle 8 and in shape an edge 14 surrounds the opening 4. Then the pre-

Diameter check explained upright with the help of the leading edge 2 'and according to the defined distance C. Coins of the correct diameter can pass through the opening 4 do not step through. They remain in the coin channel 2 and are fed to the coin collecting container according to section 3. Coins too small in diameter, however, are pushed through the opening 4 by the spring 5 and according to FIG Numbers 11, 12 are supplied to the coin return.

In the event that coins should have jammed, the wall part 10 can, as mentioned, be folded away to the outside will. A plunger 16 is used for this, which can be lifted by a cranked lifting plate 17, which with the operating handle 18 of the sales device on the Axis 19 is connected to rotary drive., In the present embodiment, it is a sales device for newspapers or magazines, which is designed in the form of a so-called fully automatic machine, in which after insertion the correct coin type and number and actuation of the handle 18 the newspaper is issued. Moving or Turning the handle 18 by a small angular amount is sufficient to bend the part 17 under the lower end to bring the plunger 16 and lift it upwards, so that the lateral pivoting away is via a lifting plate 19 of the wall part 10 causes. This position is shown in FIGS. 4, 4a. Coins located in the area of the opening 4 enter the coin return via outlet 12.

All the features shown and described, as well as their combinations with one another, are essential to the invention.
