Definitions

• the present invention relates to a coin return for payment mechanisms, installed in coin operated machines or apparatus, such as vending machines, recreational machines, etc.
• Coin returners for the above purpose comprise a coin-containing chamber or vat equipped with a coin extractor mechanism and a system for counting the supplied coins.
• Coin returners are known in which the aforementioned mechanism is constituted by ascending chains, whose links are configured to drag each one and supply a coin from the containing chamber. Also known are returners that include discs with through holes, operating as tube payers. Some and other returners are excessively bulky, so their installation presents space problems.
• Older and more traditional returners use, as a mechanism for extracting coins, a rotating disk that constitutes the bottom or side of the chamber or coin-containing cuvette, whose disk has its circumferentially distributed internal pivot surface in a concentric position with the disc.
• the pivots constitute the elements in charge of dragging the coins towards the exit mouth, during the rotation of the disk.
• This mechanism presents problems of jamming and it is also very little multi-currency, that is, it can support a very limited variety of coins of different sizes.
• the rotating disk can have recesses or conformations capable of acting as supports for dragging coins.
• the object of the invention is to solve the problems more indicated, by means of a return that includes a mechanism of extractor of coins of relatively small volume, that admits a wide variety of coins of different sizes and that does not present problems of jamming.
• the return of the invention is of the traditional type, that is to say composed of a chamber or vat with an area composed of a rotating disk provided with means for dragging the coins and is characterized in that said means of dragging are constituted by preferably radial retractable blades that protrude through the internal surface of the disk, in contact with the coins to be dragged, and are movable between an extracted position, in which they partially protrude from the surface of the disk and are capable of dragging coins and a retracted position, in which no protrude from the surface of the disk.
• the blades are elastically driven towards the extracted position and are moved towards the retracted position upon reaching the arm that intercepts the circular path of the disk or the vicinity of said arm.
• the blades can be propelled towards the retracted position by different systems, for example by the arm itself that intercepts the circular trajectory of the coins or by means of a drive device that acts on the blades when reaching this the proximities of the arm that intercepts the circular path of the coins.
• the invention is based on the existence of the retractable blades, which in their extracted position drag the coins to the arm that intercepts their circular trajectory, at which point they start to occupy the retracted position to move under said arm , thus not being an obstacle to the continuation of the rotation of the disc.
• the blades are circumferentially separated from each other a magnitude slightly larger than the diameter of the maximum size coin. With this constitution, the shovels can drag any coin size without being also cause problems with jams, since each blade can only act on the edge of a coin, attached to the surface of the disc.
• Figure 1 is a top floor of the rotating disk defining an area of the coin-receiving chamber or vat, including the means for dragging the coins of the invention.
• Figure 2 is a section of the disk, taken along the line II-II of Figure 1, on a larger scale.
• Figure 3 is a bottom view of one of the blades of Figure 1, taken according to the direction A of Figure 2.
• Figure 4 is a side view of the same blade, according to the direction B of Figure 3.
• Figure 5 is a view similar to Figure 1, showing a variant of execution in the blade retraction mechanism.
• Figure 6 is a section of the disk taken along the line VI-VI of Figure 5, on a larger scale.
• Figure 7 is a partial perspective of the disk of Figure 5.
• a rotating disk 1 which defines an area of the surface of a chamber or coin receiving chamber, of known constitution.
• the disc 1 is toothed at its periphery 2 to engage with a drive pinion, but other drive systems or means could be used.
• On the internal surface of the disc 1 support coins 3 housed in the chamber or receiving tank.
• the disc 1 is mounted on a support 4 in which a flat arm or sprat 5 is fixed, which rests on the internal surface of the disc.
• a rocker lever 6 is mounted between which and the adjacent edge of the arm or sprat 5 the outlet for the coins is defined.
• the disk 1 has means for dragging the coins 3 when turning in the direction of the arrow F.
• the arm or sprat 5 intercepts the circular path of the coins 3, moving them towards the limited outlet between said sprat and the rocker lever 6, which is pushed towards a retraction position by the currencies themselves, recovering their original position after the exit of said currency.
• the return of the invention is characterized by the special constitution of the means for dragging the coins in the disk 1.
• these dragging means are constituted by retractable radial blades 7 that partially protrude from the surface in contact with the coins, and preferably run radially, as shown in Figure 2.
• the blades 7 are movable between an extracted position, shown in Figures 2 and 4, in which they partially protrude from the surface of the disk 1 and a retracted position, in which they do not protrude from the internal surface of the disk.
• the blades are elastically driven towards the extracted position and move towards the retracted position upon reaching the arm or sprat 5 or the vicinity thereof.
• the blades 7 form part of a plate 8 with an angled profile which, in the section that runs below the disc 1, has a transverse core 9 that is placed between parallel lugs 10 of a bridge 11 attached and fixed to the rotating disk 1.
• the core 9 is articulated between the lugs 10 by the axis 12. From the articulation zone, the
• SUBSTITUTE SHEET (RULE 26) plate 8 and bridge 11 extend in portions 13 and 14 between which a helical spring 15 is mounted in order to propel the blades 7 towards the extracted position shown in figures 2 and 4.
• the support 4 in which the disk is mounted 1 forms, in the vicinity of the arm or sprat 5, a ramp 16, figure 2 on which it will support the extension 13 of the plate 8 of the blades when these reach the vicinity of the sprat 5, causing the plate 8 to swing direction of the arrow G of figure 2, producing the retraction of the blade 7, thus avoiding its collision with the edge of the arm or sprat 5, so that it does not constitute an obstacle to continue the rotation of the disc 1.
• Ramp 16 which acts as a cam for the operation of the blades 7 is located so that the retraction or concealment of the blades 7 takes place once the coin 3 dragged by said blade has caused the displacement of the tilting arm 6, figure 1 " , to carry out on the traditional way.
• the blades 7 With the constitution exposed, the blades 7 will drag the coins 3 until they exit through the mouth limited between the sprat 5 and the arm 6, becoming occupying the retraction position before reaching the edge of the sprat 5. Once the arm or sprat 5 passes, the blades 7 are pushed towards the position removed by the spring 15.
• the retraction of the blades 7 can be achieved by any other system or mechanism.
• the blades 7 could be articulated below the disc 1 along an axis perpendicular to said blade, being driven outwards by means of a spring and becoming occupying the retraction position by resting on a profile or cam similar to that referenced with the number 16 in figure 2.
• Figures 5 to 7 show another possible way of acting on the blades 7 to cause its retraction.
• the blades 7 they are also part of a right angle angled plate and are propelled towards the extracted position by means of a spring 15a mounted between the section of the blade that runs below the rotating disk 1 and a disc or closing plate 17, both fixed by screws 18
• the blades 7 extend from their inner end in a section 7a that is adjacent to the central cone 18 of the return. This section 7a is of decreasing height, until it reaches the surface of the rotating disk 1.
• the return of the invention has counting means of the coins supplied or paid.
• These means may consist of a detector mounted at the outlet, limited between the sprat 5 and the rocker lever 6, or constituted by the lever 6 itself.
