Coin counter and return device

Abstract: Coin counter and return device useful in automatic vending machines and in amusement devices and slot machines that operate by introducing coins and that are prepared to return a certain type of coin to the user, consisting of a fixed base (2) upon which there is a rotating body (4) provided with some blades (3) projecting from the fixed base (2) some pivots (5), in correspondence with which the blades (3) have some recesses (11) in such a way that in order to produce the removal of the coin (6), the latter knocks against the pivots (5) and the blades (3) impel it towards the outside upon pressing upon it with regard to a chord smaller than its diameter.

Description: The present invention consists of a coin counter and return device, useful for all types of coins irrespective of the dimensions thereof. The coin ejection mechanism can be incorporated, in rotary returning devices, in which coins are deposited in a disorganized manner in a hopper, as well as in returning devices in which the coins are stacked in a vertical column as a deposit and which are removed through the bottom part of said deposit. The coin ejection mechanism consists of a fixed base upon which the coins are deposited, on which an element projects upon which the coins knock against and likewise, a rotary element acts upon the coins causing the expulsion of the coin that knocks against the element projecting from the base, upon exerting pressure on the coin, with regard to a chord smaller than its diameter. Among coin rotary return devices consisting of a frame like a hopper where coins are deposited and with the base thereof formed by a inclined rotating circular plate, we can mention those in which the circular strip has a perimetric recess in which there is a series of stubs with a specific distance between them, in such a way that between each two continuous stubs, a coin is housed in order to be lead to the outlet. In connection with the outlet there is a strip acting as a remover, likewise having a micro, to count the coins expelled. In this way the returning device can solely and exclusively return coins of specific dimensions, in order to be able to operate normally. Thus, in the event there are coins of the same value and different sizes, only coins with specific dimensions can be returned, in such a way that the coin of an identical value and different size must be led to a second returning device or definitive moneybox. In the case of returning devices in which the coins remain stacked in a vertical hollow cylindric body and are removed through the bottom part depending on different devices the same problem arises, since the diameter of the hollow cylindric bodies must be similar to the type of coin housed, so that there is no jamming. Thus, if the diameter of the body in which the coins are deposited is somewhat larger than that of the coins, they may remain in a vertical position preventing the expulsion of the coins and producing logical jams. From US-A-3,783,885 a coin counter and return device is known, of the type that are used in automatic vending machines, and in amusement machines and slot machines to return coins to the user, being useful in rotary returning devices and in the vertical column fixed ones. the returning device of the rotating returning device is formed by a fixed circular base in inclined position, upon which a rotating body remains. The device is based on a first rotatable plate with holes having a diameter slightly exceeding the diameter of the coins to be counted and returned by the device and on a second plate having a recess the depth of which slightly exceeds the thickness of said coins. Basically, the device known from US-A-3,783,885 should be used with coins of a specific size, as the diameter of the holes 14 should slightly exceed the diameter of the coins and as the depth of the recess 18 should slightly exceed the thickness of the coins. Differently sized coins could cause jamming of the device, and it would be difficult to control that the coins are expelled one and one and therefore to count the coins expelled. Actually, the device disclosed by US-A-3,783,885 is fairly complex, including holes and a recess that have to be designed according to the specific thickness and diameter of the coins which should be counted and returned. The present invention as claimed is useful in rotary return devices, as well as fixed column ones, to return coins. All types of coins can be returned and counted irrespective of the dimensions thereof. In use thereof, in the rotary returning devices in which coins remain spread out in a storage hopper, and the remover device itself remains inclined, it is formed by a fixed circular base from which a small strip or series of aligned pivots and a rotating body project in a radial position with regard to the shaft of the circular fixed base. The cited rotating body can have different shapes, and thus can be a radial element, diametric or star-shaped element, with a variable number of tips, in such a way that for each complete rotation a different number of coins can be removed depending on the shape thereof. The removal is done upon the coin knocking against the projection of the fixed base and the rotating body, producing the removal through a hole in which there is a strip which upon being connected to a micro causes the count, although said device can be of other types. The removal of the coin is produced upon causing the contact upon the same of the projection and the rotating body with regard to a stripper smaller than its diameter, in such a way that the stresses exerted upon the coin cause a resultant that results in the removal thereof. In order to permit the correct operating of the rotating element, the same is provided on its surface backed to the base with some recesses in correspondence with the pivots. In the event that the device is incorporated for the return of coins that remain located in a fixed vertical body, the same is formed by a rotating body that will knock against the lowest coin and in the same way as described, upon putting pressure against a chord with a smaller diameter, this causes movement of the coin. When jamming takes place, upon a certain amount of time going by, there is a retraction impulse of the rotating body to cause the unblocking. In this way the device can be used without any modification for the return and counting of all types of coins. In order to complement the description that is going to be made hereinafter and for the purpose of providing a better understanding of the features thereof, the present specification is accompanied by a set of drawings in whose figures the most significant details of the invention are represented in an illustrative and non-restrictive manner. Figure 1 shows a plan view of the returning device itself, showing the pivots that project from the fixed circular base, and the rotating body as well as the strip that obstructs the coin outlet hole. Figure 2 shows a plan view of one embodiment in which the body of stacked coins remains vertical and the bottom coin remains close to a projection upon which it knocks against. Figure 3 shows a sectioned view according to axis I-I of figure 1, in which the recesses of the rotating removing body which remain in correspondence with the pivots projecting from the fixed base. Figure 4 shows a sectioned view, according to a vertical plane of figure 2, in which one sees the projection upon which the lowest coin of the vertical column remains. In view of the commented figures, and in accordance with the numbering used, we can see how the returning device itself (1) consists of a fixed circular base (2) of the frame of the returning device in which the spread out coins are located and a rotating body (4) provided with some blades (3) in such a way that from the fixed circular base (2) some pivots (5) upon which the coins (6) knock against prior to removal, project. Upon the body (4) rotating, the blades (3) of the same press the coins (6) that knock against the pivots (5), in such a way that the pressure upon them is made regarding a chord smaller than the diameter of the coin, whereby the stresses (7) acting on the coin, give a resultant (8) that makes the latter drop from the hopper through a side hole (9) that can be obstructed by a strip (10) that is urged by the action of a spring that impels it towards the inside of the hopper. The rotating body can have different shapes. It can be a radial, diametric or star-shaped strip with a variable number of tips or blades. For the counting of coins, the strip (10) can be connected to a micro, or else said counting can be done by any other conventional device. Likewise, the rotating body (4) is provided on the bottom surface of their blades with some recesses (11) that remain in correspondence with the pivots (5) projecting from the fixed base (2) to permit normal rotation of the same, and that in turn drives the coins outside. The described returning device, used in rotating returning devices can, likewise, be used in fixed vertical column returning devices inside of which the coins are stacked. Thus, the bottom coin (12) of the fixed column (13) knocks against a projection (14) and upon a rotating strip (15) pressing upon said coin (12), regarding a chord of a smaller diameter, it makes it be impelled towards the outside, producing the return of the coin. The rotating movement of the strip (15) can be replaced by linear displacement of said strip, obtaining the same effect upon the coin. In this case, in order to allow normal rotation of the strip (15) it remains overlapped upon the projection (14) passing over it upon rotating once the coin has been ejected. Upon the point of intersection of the body stop (14) of the coins and that of the strip (15) of pressure on the same remaining close to the coins, the points upon which there is pressure on the coin regarding a chord smaller than the diameter thereof whereby no matter how small the diameter of the coin is, it will always be removed. In this way, the use of the described counter-returning device permits use thereof for the return and counting of all types of coins, irrespective of the dimensions thereof, without any modification in the same. Thus, if the rotating returning device is to be used to return a coin value, whose dimensions can be different, there is not any problem, since upon being spread around in the hopper, the returning device will remove either one without distinguishing the dimensions thereof. Likewise, if it is desired to count coins of the same value and dimension or of different values and dimensions it suffices to introduce them all in the hopper of the returning device and the latter will remove them, counting them all together. The device (1) incorporates in the event that jamming takes place, which after a certain amount of time, a return impulse is produced upon the rotating body (4), which makes the jam disappear following the normal operation of the returning device.
