Description

[0001] This application is a divisional application of the invention patent application filed on September 13, 2021, with application number 202180021604.2 and entitled "Coin Hopper, Rotating Body of Coin Hopper, and Coin Processing Device". Technical Field

[0002] The present invention relates to a coin hopper for feeding coins one by one, a rotating body used in the coin hopper, and a coin processing apparatus having a coin hopper. Background Technology

[0003] A coin hopper is known, which has a container for holding multiple coins and discharges the coins one by one from the container.

[0004] For example, Japanese Patent Application Publication No. 2008-204156 describes a coin hopper comprising: a holding bowl for holding multiple coins; and a feeding mechanism for discharging the coins from the holding bowl one by one. The holding bowl has an opening at its bottom. A rotating body is disposed on the upper surface of the feeding mechanism, facing the opening. The rotating body has multiple through-holes through which coins enter. Coins entering the through-holes of the rotating body are held on a flat base disposed on the back side of the rotating body. Furthermore, a pushing protrusion is provided on the side of the through-hole to push the coin. As the rotating body rotates, the coin is pushed by the pushing protrusion and moves on the base. Coins that have moved to a predetermined position on the base are deflected by a pin of the feeding mechanism and discharged into an outlet channel. Additionally, the rotation of the rotating body agitates the coins within the holding bowl.

[0005] The protrusion abuts against the coin that has entered the through-hole, and as the rotating body rotates, it pushes the coin in the direction of movement. The protrusion wears or gets damaged due to contact with the coin. Therefore, a rotating body reinforced with reinforcing components was devised. The rotating body is formed by inserting a metal plate into resin in a single molding process. The metal plate reinforcement enhances the durability of the rotating body. A coin hopper with this durability in mind was also considered.

[0006] In addition, the circulating currency issued by a country includes coins of most denominations. Coins differ in diameter, thickness, material, and design depending on their denomination, so anyone can easily identify them. The coin processing device detects the characteristics of the coins and identifies their denomination. Furthermore, the coin processing device can also store the identified coins in a container according to their denomination. The coin processing device identifies the coin's denomination, stores the coins according to their denomination, and dispenses the stored coins as needed. The coin processing device dispenses coins of the desired amount by storing them in a coin hopper according to their denomination and controlling the hopper.

[0007] For example, regarding coin handling devices, a coin deposit and withdrawal machine is known, as disclosed in Japanese Patent Application Publication No. 2017-151818. Other examples of coin handling devices include automatic coin exchange machines. Automatic coin exchange machines store the inserted coins according to their denomination. Furthermore, the automatic coin exchange machine calculates the denomination and number of coins to be dispensed based on the exchange amount. And, based on the calculated denomination and number of coins, the automatic coin exchange machine controls the coin hopper corresponding to each denomination to dispense coins.

[0008] Compared to metal rotating bodies, resin rotating bodies are lighter but less durable. Therefore, it is considered to make a part of the rotating body metal. One method involves inserting a metal plate into the resin through integral molding. Another method involves a rotating disc as described in Japanese Patent Application Publication No. 2003-20127. This rotating disc has an ejector disc with metal push protrusions fixed to a resin disc by screws.

[0013] Patent Document 3: Japanese Patent Application Publication No. 2003-20127 Summary of the Invention

[0014] The technical problem that the invention aims to solve

[0015] Previously, the concept of a rotating body that integrally molds a metal plate and resin was considered. In conventional rotating bodies, the metal plate is coated with resin, and the metal plate enhances the strength of the resin layer. Furthermore, the protrusion that pushes the coin is reinforced by the metal plate within the resin layer. Even when the metal plate is inserted into the rotating body, the exposed resin portion can be damaged due to contact with the coin. Depending on the location of the damage, the rotating body may sometimes malfunction. Additionally, when foreign objects other than coins enter the container, the rotating body comes into contact with the foreign object, causing wear and damage. In the worst case, the rotating body becomes unusable and must be replaced. With an integrally molded rotating body, even if only a part malfunctions, the entire rotating body must be replaced. This type of rotating body has the following problems: even if a usable part is required, it must be replaced, wasting usable parts.

[0016] Rotating bodies integrally molded from resin and metal suffer from the problem of delamination due to repeated impacts on the metal-resin interface. The strength of the interface can be improved through additional processing such as surface treatment of the metal parts or by complicating the shape. However, on the other hand, improving the strength of the metal-resin interface in rotating bodies results in problems such as longer manufacturing strokes, more complex parts, and longer manufacturing time.

[0017] Furthermore, the rotating disc, which is screwed onto a metal ejector plate to push the coin, is formed by bending a metal plate twice to create the ejector protrusion. The front end of the ejector protrusion abuts against the coin to push it. Because the ejector plate is screwed onto a resin disc, force is applied to the bent portion of the ejector protrusion when pushing the coin. Therefore, the bent portion of the ejector protrusion is prone to bending and deformation. In addition, a thicker metal plate must be used to sufficiently increase strength, resulting in a heavier rotating disc. Furthermore, since the ejector protrusion is formed by bending a metal plate, and the front end of the metal plate abuts against the coin, there is a risk that the edge of the metal plate may damage the coin.

[0018] Furthermore, because the ejector plate is secured to the resin plate with screws, the screw tightening process, torque management, and other manufacturing and quality control steps become more complex. If the screws loosen, the ejector plate may move relative to the resin plate, causing the coin to fall underneath and potentially jamming.

[0019] Coin handling devices using conventional coin hoppers often experience coin feeding malfunctions due to rotating component failures. Therefore, a high level of durability in the coin hopper is desirable. A coin hopper that is easy to maintain and repair is desired, mitigating the risk of malfunctions.

[0020] Technical means for solving technical problems

[0021] The coin hopper of the present invention comprises: a container for holding coins; a base for supporting the coins; a rotating body having a plurality of separation holes for holding the coins one by one, fixed to a rotating shaft and disposed opposite to the base; and a control pin disposed on the conveying path of the coins held by the rotating body, abutting against the conveyed coins to change the direction of movement of the coins. The coin hopper conveys the coins contained in the container on the base while held in the separation holes, causing the coins to abut against the control pin and move the coins in the discharge direction. The coin hopper is characterized in that the rotating body comprises: a first resin rotating body made of resin; and a metal pusher plate disposed for pushing the coins in each of the separation holes. The first resin rotating body has a first through hole, and the first resin rotating body or the second resin rotating body has a positioning protrusion at a position corresponding to the first through hole. The first resin rotating body has a first abutment portion, and the second resin rotating body has a second abutment portion. The metal rotating body is clamped between the first resin rotating body and the second resin rotating body when the pushing piece is exposed from the first resin rotating body. The positioning protrusion is fitted into the first through hole to restrict relative movement between the metal rotating body and the first resin rotating body in the rotational direction. The first resin rotating body, the metal rotating body, and the second resin rotating body are fixed by engaging the first abutment portion and the second abutment portion.

[0022] The coin processing apparatus of the present invention is characterized by having the coin hopper and a coin receiving part for receiving and collecting the coins discharged from the coin hopper, wherein multiple coin hoppers are arranged and the coin receiving part receives the coins discharged from each of the coin hoppers.

[0023] The rotating body of the coin hopper of the present invention comprises: a container for holding coins; a base for supporting the coins; a rotating body having a plurality of separation holes for holding the coins one by one, fixed to a rotating shaft and disposed opposite to the base; and a control pin disposed on the conveying path of the coins held by the rotating body, abutting against the conveyed coins to change the direction of movement of the coins. The rotating body of the coin hopper conveys the coins contained in the container on the base while held in the separation holes, causing the coins to abut against the control pin and move the coins in the discharge direction. The rotating body of the coin hopper is characterized in that the rotating body comprises: a first resin rotating body made of resin; and a metal abutment for pushing the coins disposed on each of the separation holes. The device comprises a metal rotating body for pushing the push plate and a second resin rotating body made of resin. The metal rotating body has a first through hole.

The positioning protrusion is fitted into the first through hole to restrict relative movement in the rotational direction between the push plate and the metal rotating body. By engaging the first abutment portion and the second abutment portion, the first resin rotating body, the metal rotating body, and the second resin rotating body are fixed.

[0046] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The drawings are only schematic representations of the invention to a degree that allows for a thorough understanding. Therefore, the invention is not limited to the examples shown in the drawings. Furthermore, in the drawings, common constituent components are labeled with the same component symbols, and repeated descriptions of these are omitted.

[0047] First, use Figure 1 Let me explain the coin hopper. Figure 1 It is a 3D diagram of a coin hopper.

[0048] The coin hopper 1 comprises: a container 2 for storing coins 10; and a body 3 for separating and discharging the coins 10 one by one. The container 2 can be attached to or removed from the body 3. The lower part of the container 2 is provided with a guide part 8, which is a generally circular opening. The upper part of the body 3 is provided with a rotating body 5. The guide part 8 is arranged along the outer periphery of the rotating body 5 to guide the coins 10 to accumulate on the rotating body 5.

[0049] The rotating body 5 has multiple separation holes 6. Each separation hole 6 is a through hole that passes through both sides of the rotating body 5. A coin 10 enters the separation hole 6 and slides on the base 7 under the influence of the rotating body 5. A control pin is positioned at a predetermined location on the base 7. When the coin 10 comes into contact with the control pin, its trajectory changes to the direction of the delivery outlet 4, and it is discharged from the delivery outlet 4.

[0050] The upper part of the main body 3 has a flat base 7, on which a rotating body 5 rotates. The guide part 8 of the container 2 is arranged along the outer periphery of the rotating body 5. The opening of the rotating body 5 and the guide part 8 face each other. The base 7 is inclined such that the side with the feed outlet 4 is higher in the vertical direction than the opposite side. Because the base 7 is inclined, the coins 10 are easily concentrated on the lower side of the container 2. The rotating body 5 passes under the stacked coins 10, causing the coins 10 to enter the separation hole 6. The coins 10 are transported by the rotating body 5 to the feed outlet 4.

[0051] In this way, the coin hopper 1 feeds the coins 10 in the container 2 one by one into the separation hole 6 of the rotating body 5 and transports them to the discharge outlet 4 for discharge.

[0052] Furthermore, the size, material, and design of the coin 10 vary depending on the coin type. The coin processing device places the coin hopper 1 of the specified coin type in a predetermined position. Therefore, the coin hopper 1 has a recognition hole 9 corresponding to the coin type. The coin processing device places a protrusion corresponding to the recognition hole 9 in a predetermined position. The coin hopper 1 with the corresponding recognition hole 9 is positioned in the predetermined position of the coin processing device.

[0053] The following is a further detailed description of coin hopper 1. Figure 2This is a 3D view showing the state of the coin hopper removing the coin container.

[0054] The coin hopper 1 is equipped with an electric motor 11 for driving the rotating body 5. The rotation of the electric motor 11 is controlled by a control circuit (not shown). A gear (not shown) is disposed inside the main body 3, connecting the electric motor 11 and a rotating shaft (not shown) to which the rotating body 5 is fixed. The rotating shaft passes through a through hole provided in the base 7. The rotating body 5 is fixed to the rotating shaft protruding from the base 7. The stirring part 12 is a protrusion disposed at the center of rotation of the rotating body 5, which stirs the coin 10 so that it does not remain concentrated in one position. Furthermore, the stirring part 12 has a mechanism for fixing the rotating body 5 to the rotating shaft. Additionally, making the part fixed to the rotating shaft metal can increase strength. For example, the stirring part 12 can also be made of metal. The rotating body 5 is also provided with stirring blades 18. The stirring blades 18 are protrusions provided on the surface of the rotating body 5. The stirring blades 18 stir the accumulated coins 10. The stirring blades 18 are arranged radially from the center of the rotating body 5. In addition, in order to improve the stirring ability, a recess is provided between adjacent stirring blades 18, which complicates the surface of the rotating body 5.

[0055] The uneven surface of the rotating body 5 effectively agitates the accumulated coins 10, making it easier for the coins 10 to enter the separation hole 6. Therefore, the rotating body 5 is thicker. To reduce the weight of the rotating body 5, part of it is made of plastic and part of it is made of metal. The rotating body 5 maintains its strength while remaining lightweight. Furthermore, by making the part of the rotating body 5 that contacts the coin 10 metal, wear and damage caused by contact with the coin 10 can be prevented.

[0056] The rotating body 5 rotates counterclockwise. A groove for the dodging control pin 13 is provided on the back side of the rotating body 5. Additionally, a pusher plate for pushing the coin 10 is disposed on the back side of the rotating body 5. Furthermore, a groove is disposed between the outer periphery of the rotating body 5 and the separation hole 6, allowing the coin 10 to pass through. The coin 10, entering the separation hole 6, abuts against the control pin 13 and is guided towards the delivery outlet 4. The coin 10 is pushed between the fixed roller 15 and the moving roller 16. The moving roller 16 is subjected to force in the direction of the fixed roller 15. When more than half of the coin 10 has entered between the fixed roller 15 and the moving roller 16, the coin 10 will pass through the space between them. At this time, the coin 10 is violently moved towards the delivery outlet 4 due to the force exerted by the moving roller 16. The discharge sensor 14 detects the discharged coin 10. The detection result is output to the control circuit (not shown). The control circuit can count the discharged coins 10. The control pin 13 is configured in the transport path of the coin 10 carried by the rotating body 5.

[0057] The outer periphery of the rotating body 5 is provided with an outer wall 17 that restricts the movement of the coin 10. In order to guide the coin 10 to the feed outlet 4, at least between the fixed roller 15 and the moving roller 16, there is no outer wall 17. The coin 10 can move toward the feed outlet 4 from this part.

[0058] Next, let's explain the rotation body 5. Figure 3 This is a three-dimensional view of the rotating body. The commonly used coin 10 is made of metal. The upper surface of the rotating body 5 is a first resin part 20 made of resin such as plastic. Considering strength, durability, and processability, the material of the first resin part 20 is preferably engineering plastic. The rotating body 5 is divided into three components, which will be described later.

[0059] The rotating body 5 wears down due to contact with the coin 10. Therefore, to reduce or even prevent wear, the rotating body 5 has both metal and resin parts. The entire rotating body 5 could also be made of metal. However, to reduce the weight of the rotating body 5, it is preferable to make a portion of it made of resin such as plastic. Furthermore, making the parts of the rotating body 5 that experience intense wear metal improves its durability. The part of the rotating body 5 that experiences intense wear is a pusher plate that pushes the coin 10, which has entered the separation hole 6. The pusher plate abuts against the control pin 13 when the coin 10... Figure 2 ), fixed roller 15 ( Figure 2 ), 16 movable rollers Figure 2 The pusher plate is pushed in a state where it is in the pushing position. Therefore, the pusher plate is subjected to a reaction force equivalent to the pushing force. The force is especially strong at the end of the pusher plate. Therefore, the pusher plate is made of metal to improve durability. The pusher plate is located on the back side of the rotating body 5.

[0060] The rotating body 5 has five separation holes 6. The rotating body 5 has at least one separation hole 6. The maximum number of separation holes 6 is determined by the size of the rotating body 5 and the size of the coin 10.

[0061] Next, let's look at the diagram of the back side of the rotating body 5. Figure 4 This is a diagram illustrating the back side of the rotating body.

[0062] The rotating body 5 has a shaft hole 23 at its center for inserting a rotating shaft. The rotating shaft has a locking part configured to pass through the shaft center and be perpendicular to the shaft direction. A shaft locking groove 24, which engages with the locking part, is located at the center of the rotating body 5.

[0063] The first resin section 20 has five separation holes 6 at equal intervals from its rotation center. Each separation hole 6 is a through hole penetrating both the front and back surfaces of the first resin section 20. The area surrounding each separation hole 6 is formed with a thick wall. The portion of the metal section 22, excluding the pusher plate 25, is made of flat metal and is configured to be flush with the substrate 7. Figure 2 Parallel. The push plate 25 is formed to push the edge of the plate towards the substrate 7 ( Figure 2 The direction of the bend is approximately perpendicular. The surface of the pusher piece 25 that contacts the coin is flat. For example, the metal part 22 can be easily manufactured by cutting off the outer periphery by stamping a flat plate and bending a portion of the pusher piece 25 by stamping. The metal part 22 does not require surface treatment to create tiny bumps and depressions on its surface.

[0064] The back side of the first resin portion 20 of the rotating body 5 has a recess 31, which protrudes from the central portion surrounding the shaft hole 23 and the shaft locking groove 24, the periphery of the first resin portion 20, and the periphery of the separation hole 6, and opens on the back side of the rotating body 5. A positioning protrusion 33 is provided in the recess 31 between adjacent separation holes 6. The positioning protrusion 33 is a protrusion provided on the back side of the first resin portion 20. The recess 31 houses a metal portion 22. The portion of the metal portion 22 protruding from the center of the first resin portion 20 and the portion corresponding to the positioning protrusion 33 have through holes. The metal portion 22 is fitted into the central protrusion of the first resin portion 20 and fixed to the first resin portion 20. Furthermore, the metal portion 22 disposed in the recess 31 is fitted into the positioning protrusion 33 and fixed to the first resin portion 20. The metal portion 22 is a metal plate such as stainless steel or an aluminum alloy. The metal portion 22 has a bent portion between adjacent separation holes 6, and the bent portion functions as a pusher piece 25. Each positioning protrusion 33 is arranged at equal intervals from the rotation center of the rotating body 5. The pusher plate 25 is arranged on a circumference with a radius equal to the distance from the rotation center to the positioning protrusion 33. Additionally, the inverting plate 26, which abuts against the coin when the rotating body 5 is inverted, is also arranged on a circumference with a radius equal to the distance from the rotation center to the positioning protrusion 33. Because the pusher plate 25 is constructed as a bent flat plate, the contact surface with the coin is a flat surface.

[0065] The reversing plate 26 is positioned on the forward rotation side of the separation hole 6 of the rotating body 5. Conversely, the pushing plate 25 is positioned on the reverse rotation side of the separation hole 6 of the rotating body 5. The pushing plate 25 pushes the coin 10 when the rotating body 5 is rotating forward, and the reversing plate 26 pushes the coin 10 when the rotating body 5 is rotating backward. That is, the coin entering the separation hole 6 is positioned between the pushing plate 25 and the reversing plate 26 and is thus transported.

[0066] A linear locking groove 37 is formed on the periphery of the first resin portion 20 and on the inner wall of the recess 31. The locking groove 37 is formed on the inner wall of the outer periphery of the recess 31. The locking groove 37 is a groove that engages with a locking protrusion (described later) provided on the second resin portion 21. The locking groove 37 is arranged along the outer periphery of the first resin portion 20 and has a narrow and elongated shape.

[0067] Figure 5This is a perspective view of the rear side of the rotating body. It is a perspective view of the rotating body 5 as seen from the rear side. The rotating body 5 includes: a metal part 22; and resin parts, namely a first resin part 20 and a second resin part 21. The metal part 22 is inserted into the recess 31 of the first resin part 20. The second resin part 21 is fixed to the first resin part 20. The metal part 22 is fixed between the first resin part 20 and the second resin part 21. The second resin part 21 has a through hole, i.e., a pusher hole 30, at a position corresponding to the pusher piece 25 of the metal part 22. Additionally, the second resin part 21 has a through hole at a portion corresponding to the positioning protrusion 33. The second resin part 21 covers the metal part 22 to prevent the metal part 22 inserted into the recess 31 from falling out. The pusher piece 25 is configured to protrude from the resin part through the pusher hole 30. The metal part 22 is fixed to the second resin part 21 by fitting the pusher piece 25 into the pusher hole 30. The first resin portion 20 and the second resin portion 21 can also be referred to as the first resin rotating body forming the resin portion of the rotating body 5, and the metal portion 22 can also be referred to as the metal portion forming the rotating body 5. Metal Rotating Body A pusher plate 25 is provided for each separation hole 6 located on the rotating body 5. A central protrusion 34 corresponds to the pusher plate 25 and is located adjacent to it. That is, the central protrusion 34 is provided for each pusher plate 25 to prevent deformation of the rotating body 5 in the direction of rotation of the pusher plate 25. The metal part exposed from the second resin part 21 on the side of the base 7 is only the pusher plate 25 exposed through the pusher plate hole 30. The part that allows the metal part to contact the coin is minimized. It can also be said that the part of the resin part that is subjected to strong force from the coin 10 is replaced with a metal part.

[0068] The outer periphery of the first resin section 20 is provided with a first step 28 and a second step 29 corresponding to each separation hole 6. The outer periphery of the first resin section 20 has an uneven surface formed by the first step 28 and the second step 29 corresponding to the separation holes 6. Five peripheral protrusions 32 are formed on the outer periphery of the first resin section 20. Recesses are formed between the peripheral protrusions 32, allowing a coin 10 entering the separation hole 6 to pass through. A coin 10 entering through the separation hole 6 can move in a channel that is wider than the opening of the separation hole 6 on the back side of the first resin section 20 and the second resin section 21. Because this channel is designed to be wide enough for one coin 10 to enter, other coins 10 will not enter through the separation hole 6 when a coin 10 is present.

[0069] The second resin portion 21 includes: a radially extending base 36; and an inner peripheral protrusion 35 and a central protrusion 34 protruding from the base 36. The central protrusion 34 has a through hole through which the positioning protrusion 33 passes. The second resin portion 21 is made of resin such as plastic. The second resin portion 21 is preferably made of resin such as engineering plastic. Furthermore, the second resin portion 21 is preferably made of the same material as the first resin portion 20. Since the second resin portion 21 does not come into contact with the coin 10, it can be made of a resin with lower durability in contact with the coin 10 compared to the first resin portion 20.

[0070] Rotating body 5 is located on base 7 ( Figure 2 Above. To allow rotation, the rotating body 5 must have a clearance control pin 13 ( Figure 2 The groove of the inner peripheral protrusion 35 and the outer peripheral protrusion 32. The push plate 25, the central protrusion 34, and the reversing plate 26 are arranged between the inner peripheral protrusion 35 and the outer peripheral protrusion 32, thereby forming a concentric circle of concave and convex shapes. Control pin 13 ( Figure 2 When the rotating body 5 rotates, it passes through the concentric recesses. The surfaces of the pushing plate 25, the central protrusion 34, the reversing plate 26, the inner peripheral protrusion 35, and the outer peripheral protrusion 32 are formed to be substantially coplanar. The positioning protrusion 33 is configured to be coplanar with the central protrusion 34 or not protrude.

[0071] The coin 10, entering the separation hole 6, is surrounded by the push plate 25, the inverting plate 26, the central protrusion 34, and the outer peripheral protrusion 32, which restrict its movement and transport it. When the rotating body 5 rotates forward, it is moved by the push plate 25. When the rotating body 5 rotates backward, it is moved by the inverting plate 26. The inverting plate 26 is made of resin, but it can also be formed by bending the metal part 22, just like the push plate 25. The rotating body 5 rotates backward less often than forward. Therefore, compared to the push plate 25, the inverting plate 26 has less chance of wear and damage due to contact with the coin 10. The inverting plate 26 can also be made of resin, but it is preferable to make it of metal. Like the push plate 25, the inverting plate 26 can also be formed by bending a portion of the metal part 22. The metal part 22 is made of a harder material than the first resin part 20 and the second resin part 21. The rotating body 5's durability is significantly improved due to the metal part 22. If the durability of the rotating body 5 is high enough, the replacement frequency of the rotating body 5 can be reduced. If the durability of the rotating body 5 is sufficient, the first resin part 20 and the second resin part 21 can also be fixed together with an adhesive. Alternatively, the first resin part 20 and the second resin part 21 can be fixed together using a fitting mechanism and adhesive. When fixed by adhesive, the part can be replaced by removing the adhesive portion. Alternatively, the resin part can be replaced while leaving the metal part 22 intact.

[0072] Coins 10 are stacked on the first resin portion 20. Because coins 10 sometimes fall from above and collide with the first resin portion 20, sufficient durability is required. Comparing the thickness of the first resin portion 20 and the second resin portion 21 between adjacent separation holes 6 in the rotation direction of the rotating body 5, the first resin portion 20 is thicker than the second resin portion 21. Furthermore, it is preferable that, as mentioned above, the first resin portion 20 is thicker than the combined thickness of the second resin portion 21 and the metal portion 22. Making the first resin portion 20 thicker improves its durability. The durability of the rotating body 5 is improved by pushing the metal portion 22 and the first resin portion 20 of the coin 10. This reduces the possibility of the rotating body 5 becoming fatally damaged and requiring replacement.

[0073] Next use Figure 6 and Figure 7 Let me explain the second resin part 21 and the metal part 22. Figure 6 This is the first diagram illustrating the structure of a solid of revolution. Figure 7 This is the second diagram illustrating the structure of a solid of revolution. Figure 6 This is a view taken from the metal part 22 side. Figure 7 This is a view taken from the second resin section 21 side.

[0074] The second resin section 21 is provided with a push plate hole 30 corresponding to the push plate 25. The push plate hole 30 is a through hole that passes through both sides of the second resin section 21. The push plate 25 is fitted into the push plate hole 30.

[0075] The second resin portion 21 has a first through hole 38 with a circular opening at its center. The metal portion 22 has a third through hole 40 with a circular opening at its center. The first through hole 38 and the third through hole 40 have the same diameter. The first through hole 38 and the third through hole 40 are fitted together with the first resin portion 20. Figure 5 The central protruding portion. The metal part 22 has five arms with push plates 25 formed thereon. Each of the five arms is provided with a push plate 25. The five push plates 25 are constructed as a single integral part. The metal part 22 and the second resin part 21 can be easily installed or removed.

[0076] Five arms extending radially from the center of the second resin section 21 each have a second through hole 39 with a circular opening. Five arms extending radially from the center of the metal section 22 each have a fourth through hole 41 with a circular opening. The second through holes 39 and the fourth through holes 41 have the same diameter. The second through holes 39 and the fourth through holes 41 are equipped with a positioning protrusion 33. Figure 5 The openings correspond to the shape of the holes. That is, the second through hole 39 and the fourth through hole 41 are through holes with the same opening shape. The second through hole 39 and the fourth through hole 41 are fitted with positioning protrusions 33. Figure 5 Positioning protrusion 33 ( Figure 5The pusher piece 25 and the central protrusion 34 are positioned in a predetermined position. That is, the second through hole 39 and the fourth through hole 41 are fitted into the positioning protrusion 33, thereby positioning the pusher piece 25 adjacent to the central protrusion 34. The positioning protrusion 33 can also be referred to as the engaging protrusion that engages the second resin part 21 and the metal part 22 into the first resin part 20. Since the second through hole 39 can be fitted into the positioning protrusion 33, it can also be replaced by a non-through hole.

[0077] The second resin portion 21 and the metal portion 22 overlap in a top view. In the top view, the metal portion 22 is configured such that the portion of the pusher piece 25 does not extend beyond the second resin portion 21.

[0078] The arm-shaped side 44 at the front end of the five radially extending portions of the second resin part 21 is aligned with the recess 31. Figure 4 The arm side 44 is provided with a locking and engaging protrusion 42. The locking and engaging protrusion 42 is a linear protrusion provided on the arm side 44. The locking and engaging protrusion 42 engages in the locking and engaging groove 37. Figure 4 The locking engagement protrusion 42 is engaged in the locking engagement groove 37. Figure 4 This allows the metal part 22 and the second resin part 21 to be fixed to the first resin part 20. Figure 4 That is, it can be said that they are respectively the first resin part 20 ( Figure 4 The first resin part 20 has a first connecting portion such as a locking groove 37, and the second resin part 21 has a second connecting portion such as a locking protrusion 42. The first connecting portion and the second connecting portion are joined together to fix the first resin part 20 and the second resin part 21. Alternatively, the first resin part 20 and the second resin part 21 can be securely fixed by means of an adhesive.

[0079] Each of the five radially extending portions from the center of the second resin portion 21 has a thick-walled portion 43 at its front end. The thick-walled portions 43 are arranged at equal intervals from the rotation center of the second resin portion 21. The thick-walled portions 43 enhance the strength of the outer periphery of the second resin portion 21, and are fixed to the first resin portion 20 (…). Figure 4 In the case of [missing information], it prevents deformation such as bending or torsion. The thick-walled portion 43 increases strength so that the locking and fitting protrusion 42 will not deform. The thick-walled portion 43 is approximately equal in thickness to the metal portion 22 and is twice the thickness of the base portion 36. The locking and fitting protrusion 42 is disposed at the center of the thick-walled portion 43 in the thickness direction.

[0080] A central protrusion 34, protruding from the base 36 of the second resin portion 21, is positioned adjacent to the push plate hole 30. That is, when the second resin portion 21 is engaged with the metal portion 22, the push plate 25 is adjacent to the central protrusion 34. When the coin is pushed by the push plate 25, the push plate 25 is subjected to force. When the push plate 25 is subjected to force, it is prevented from deforming by the adjacent central protrusion 34. The central protrusion 34 is made of resin, but because it does not directly contact the coin, it is not subject to being cut by the coin. The push plate 25 is positioned when the coin abuts against the control pin 13 (…). Figure 2 When the coin is pushed while the roller 16 is in motion, the pusher plate 25 is subjected to a strong force. If the pusher plate 25 is made of plastic, it is at risk of breakage. Even if the pusher plate 25 is made of metal, it is at risk of bending to the opposite side relative to the direction of rotation. Because the central protrusion 34 is arranged adjacent to the pusher plate 25, the central protrusion 34 can prevent the pusher plate 25 from deforming. In addition, the surface of the pusher plate 25 that contacts the central protrusion 34 is supported by the central protrusion 34. Because the entire surface is supported, the pusher plate 25 is prevented from bending due to contact with the coin 10. The width of the central protrusion 34 is approximately the same as that of the pusher plate 25, but the length of the central protrusion 34 is configured to be longer than the width of the central protrusion 34, which increases the strength in the direction of rotation. The central protrusion 34 will not deform even when subjected to force from the pusher plate 25.

[0081] Next use Figure 8 This describes the action of discharging coins from the coin hopper. Figure 8 It is a diagram illustrating the operation of the coin hopper. Figure 8 (a) shows the first state of the coin hopper's operation. Figure 8 (b) shows the second state illustrating the operation of the coin hopper. Figure 8 (c) represents the third state, which shows the operation of the coin hopper. Figure 8 (d) represents the fourth state, which shows the operation of the coin hopper. Figure 8 (e) represents the fifth state, which shows the operation of the coin hopper. Figure 8 (f) represents the sixth state, which shows the operation of the coin hopper.

[0082] Figure 8 (a) to (f) are performed in a manner that reveals the contact state between coin 10 and rotating body 5, and container 2 is removed. Figure 1 ), First resin part 20 ( Figure 3 A top view of the state. Figure 8 (a) to Figure 8 The (f) buttons sequentially display the state changes. Additionally, coin 10 is shown as a dashed line.

[0083] The rotating body 5 rotates counterclockwise, causing the coin 10, which has entered the recess of the rotating body 5, to move. The coin 10, surrounded by the outer wall 17 and the recess of the rotating body 5, is propelled and carried by the pusher plate 25. The pusher plate 25 passes between two control pins 13.

[0084] Figure 8 Image (a) shows the state of the coin 10 up to the position where it abuts against the control pin 13. Additionally, the coin 10 contacts the side wall of the second resin section 21 and the pusher plate 25.

[0085] As the rotating body 5 rotates, the coin 10 is pushed by the pusher plate 25 in the direction of rotation of the rotating body 5. However, the movement of the coin 10 in the direction of rotation of the rotating body 5 is restricted by the control pin 13. Therefore, the direction of movement of the coin 10 changes towards the delivery outlet 4. The force that changes the direction of movement of the coin 10 is applied to the pusher plate 25.

[0086] Figure 8 (b) shows the state where the coin 10 moves towards the feed outlet 4 and contacts the moving roller 16. The coin 10 is pushed by the pusher plate 25 as the rotating body 5 rotates. The coin 10 moves away from the control pin 13 on the center side of the rotating body 5 and becomes contacted with the control pin 13 on the outer side. The contact position of the pusher plate 25 with the coin 10 moves away from the center of the rotating body 5 as the rotation continues.

[0087] Figure 8 (c) describes the state where the coin 10 moves towards the feed outlet 4 as the rotating body 5 rotates, and comes into contact with the fixed roller 15 and the movable roller 16. The coin 10, pushed by the pusher plate 25, moves towards the feed outlet 4 and away from the control pin 13. When the coin 10 is not in contact with the fixed roller 15 and the movable roller 16, the distance between the fixed roller 15 and the movable roller 16 is less than the diameter of the coin 10. However, as the rotating body 5 continues to rotate, the coin 10 pushes the movable roller 16, widening the distance between the fixed roller 15 and the movable roller 16. Because the movable roller 16 can move away from the fixed roller 15, the coin 10 can move towards the feed outlet 4. The pusher plate 25 is subjected to the force that pushes the movable roller 16.

[0088] Figure 8 Image (d) shows the state in which the coin 10 moves towards the feed outlet 4 between the fixed roller 15 and the movable roller 16. When the coin 10 contacts both the fixed roller 15 and the movable roller 16, and is thus pushed by the pusher plate 25, the movable roller 16 moves away from the fixed roller 15. The coin 10 passes between the fixed roller 15 and the movable roller 16, and then moves towards the feed outlet 4.

[0089] Figure 8(e) shows the state where the distance between the fixed roller 15 and the movable roller 16 is equal to the diameter of the coin 10. The coin 10 is pushed by the push plate 25, causing the coin 10 to move further in the direction of the feed outlet 4 until the distance between the fixed roller 15 and the movable roller 16 exceeds the diameter of the coin 10.

[0090] Because the outer peripheral end of the rotating body 5 of the pusher piece 25 contacts the coin 10, the reaction force when pushing the coin 10 is applied to the end of the pusher piece 25. That is, because the pusher piece 25 applies a strong force, if the pusher piece 25 is made of resin, it will deform and wear. For example, when the edge of the coin 10 strongly impacts the resin part, the resin part may sometimes be chipped.

[0091] Figure 8 (f) shows the state where coin 10 leaves push plate 25 and moves towards outlet 4. Moving roller 16 is subjected to spring force in the direction close to fixed roller 15. Coin 10 is pushed by push plate 25 until the distance between fixed roller 15 and moving roller 16 becomes the diameter of coin 10. Beyond this state, coin 10 is pushed by moving roller 16 and moves towards outlet 4. Moving roller 16 pushes the side of coin 10 and moves it closer to fixed roller 15. Moving roller 16 returns to its initial position.

[0092] Because the movable roller 16 is subjected to a spring force in the direction close to the fixed roller 15, it moves towards the fixed roller 15 due to the spring force. The coin 10 is pushed by the movable roller 16 and pushed out towards the feed outlet 4. In addition, the discharge sensor 14 detects that the coin 10 has passed through.

[0093] The end of the pusher piece 25 closer to the center of the contact surface with the rotating body 5 is designated as the first end, and the end farther away is designated as the second end. The pusher piece 25 is in contact with the first end when the coin 10 is only in contact with the control pin 13 on the side closer to the center of the rotating body 5. The pusher piece 25 is in contact with the second end when the coin 10 is only in contact with the control pin 13 on the side farther from the center of the rotating body 5. That is, the surface of the pusher piece 25 that contacts the coin 10 is positioned in the direction intersecting the line passing through the center of the rotating body 5 in a top view. The contact position between the pusher piece 25 and the coin 10 moves from the direction of the rotation center of the rotating body 5 towards the direction away from the rotation center as the rotating body 5 rotates. The coin 10 moves away from the rotation center as the rotating body 5 rotates. Because the control pin 13 is positioned at a predetermined location on the base 7, the coin 10 changes direction and is ejected when it is transported to this predetermined location.

[0094] When the push plate 25 abuts against the control pin 13, it changes the direction of movement of the coin 10 from the rotation direction of the rotating body 5 to the direction between the fixed roller 15 and the moving roller 16. Therefore, the coin 10 is subjected to force in a direction intersecting the rotation direction of the rotating body 5. Depending on the direction of the force, the rotation of the rotating body 5 may stop, resulting in a coin jam. In the worst case, this could cause damage to parts.

[0095] Furthermore, the length of the face of the pusher piece 25 that abuts against the coin 10 is less than the distance between the two control pins 13. That is, the pusher piece 25 passes between the two control pins 13 as the rotating body 5 rotates. Additionally, because the end of the pusher piece 25 that abuts against the coin 10 contacts the coin 10, the end is subjected to a strong force. Therefore, it is preferable to be made of metal, especially hard metals such as stainless steel, ferrous alloys, titanium alloys, and aluminum alloys.

[0096] Next, let me explain the coin handling device. Figure 9 This is a perspective view illustrating an example of a coin-handling device.

[0097] The coins 10 stored in the storage container 60 of the coin processing device 50 contain a mixture of various denominations. The coin processing device 50 sorts the coins 10 stored in the storage container 60 according to their denominations and stores them in the coin hopper 1. Furthermore, the coin processing device 50 is a device that discharges coins 10 from the coin hopper 1 according to instructions from external equipment. This type of coin processing device 50 is equipped in POS systems and coin exchange machines, etc.

[0098] The coin handling device 50 comprises a separating section 51, an identification section 52, and a dispensing section 53. Coins 10 of different denominations are fed into the storage container 60 in a mixed state. In the separating section 51, each coin 10 is transferred to the identification section 52. In the identification section 52, the characteristics of each coin 10 being transported are detected by a sensor (not shown) to determine the coin type. The coin 10 whose denomination has been determined is transferred from the identification section 52 to the dispensing section 53. In the dispensing section 53, the coin 10 whose denomination has been determined is stored in the corresponding coin hopper 1.

[0099] In the dispensing unit 53, the coin 10 is conveyed along the track 58 by the conveying pin 54. A coin flipper 55 is arranged along the track 58. The coin flipper 55 is driven by a drive unit (not shown) to make the path of the coin 10 variable. Depending on the state of the coin flipper 55, the coin 10 may fall onto the slider 56, or it may not fall and may pass through. If the coin 10 falls onto the slider 56, it passes through the guide channel 57 and is stored in the container 2 of the coin hopper 1.

[0100] Coins 10 that have been identified by coin type are stored in one of the four coin hoppers 1, or guided to the coin return channel 61 and discharged to the coin dispensing tray 62. Because there are four coin hoppers 1, coins 10 of four different coin types can be stored; other coin types are not accepted and are discharged. The multiple coin hoppers 1 arranged in a row discharge onto the discharge belt 59. That is, the discharge belt 59 can also be called a coin receiving section that receives the coins 10 discharged from the multiple coin hoppers 1 arranged in a row. By rotating the discharge belt 59, the coins 10 can be collected in one place.

[0101] Coins 10 discharged from the outlet 4 of the coin hopper 1 are placed on the discharge belt 59. The discharge belt 59 is driven by a drive unit (not shown) to transport the coins 10 to the coin tray 62.

[0102] Secondly, use Figures 10 to 14 Let's illustrate a second example of a rotating body. The second rotating body 70 can be applied to the rotating body of the aforementioned coin hopper. Figure 10 This is a three-dimensional diagram illustrating an example of a second solid of revolution.

[0103] The second rotating body 70 has a metal rotating body (described later) sandwiched between the two resin rotating bodies of the third resin part 72 and the fourth resin part 73. The resin rotating body is preferably made of engineering plastic or other plastics with good machinability and high durability. The metal rotating body is preferably made of metals with good machinability and high durability, such as iron alloys, titanium alloys, or aluminum alloys.

[0104] The third resin section 72 has stirring protrusions 71 between the separation holes 6 to stir the coins inside the container. The second rotating body 70 has a stirring section 12 at the center of rotation. The stirring protrusions 71 are protrusions that extend radially from the stirring section 12 disposed on the front side of the third resin section. By rotating the second rotating body 70, the stirring section 12 and the stirring protrusions 71 stir the coins inside the container.

[0105] The fourth resin section 73 includes a wall section 76 that is erected along its outer periphery. The wall section 76 includes a plurality of locking protrusions 75. The locking protrusions 75 are engaged at predetermined positions on the outer periphery of the third resin section 72, thereby securing the third resin section 72 and the fourth resin section 73. The fourth resin section 73 is provided with a discharge groove 27 for each separation hole 6 through which the discharged coin passes.

[0106] Downstream of the second rotating body 70 in the direction of rotation of the separation hole 6, there is a reversing plate 26 that abuts against the coin when the second rotating body 70 is reversed. The discharge groove 27 allows the coin to move from the inner circumference to the outer circumference of the wall portion 76.

[0107] Next, the structure of the second rotating body 70 will be explained. Figure 11 This is the first diagram illustrating the structure of an example of a second solid of revolution. Additionally, Figure 11 This shows the state in which the fourth resin part 73 of the second rotating body 70 is embedded with the second metal part 74. Figure 12 This is the second diagram illustrating the structure of an example of a second body of revolution. Figure 12 This is a perspective view illustrating a portion of the fourth resin part 73 of the second rotating body 70.

[0108] A rotating shaft is inserted through the third shaft hole 83 at the rotation center of the second metal part 74. The second metal part 74 has arms of metal plates radiating outwards in three directions at equal intervals from the third shaft hole 83 between adjacent separation holes 6. Each arm of the three-direction extending metal plate has a bend at approximately a right angle at its front end. The bends serve as the second pusher plate 77 and the third pusher plate 78 for pushing the coin. The second pusher plate 77 is inserted into the second pusher plate hole 79 penetrating both sides of the fourth resin part 73, with its front end protruding from the back side of the fourth resin part 73. The third pusher plate 78 is inserted into the third pusher plate hole 80 penetrating both sides of the fourth resin part 73, with its front end protruding from the back side of the fourth resin part 73.

[0109] A peripheral through hole 82 is provided at the base of the wall portion 76 of the fourth resin portion 73. The peripheral through hole 82 is a through hole that penetrates both sides of the fourth resin portion 73. A peripheral through hole 82 is provided at a position corresponding to the locking protrusion 75. When the third resin portion 72 is hooked onto the locking protrusion 75, the wall portion 76 can be easily bent to prevent damage.

[0110] Two locking protrusions 75 are disposed between adjacent separation holes 6. A third pushing plate 78 is disposed between adjacent locking protrusions 75. The rotation center of the second metal part 74 of the second rotating body 70 is fixed to the rotation axis.

[0111] The second metal part 74 has a fifth through hole 84 on its upstream side in the rotational direction of the second push plate 77. The fifth through hole 84 is disposed on each arm of the second metal part 74. The fifth through hole 84 is a through hole that penetrates both sides of the second metal part 74. A protrusion, described later, is fitted into the fifth through hole 84 to prevent the second metal part 74 from wobbling in the rotational direction. The fourth resin part 73 has a second positioning protrusion 81, which fits into the sixth through hole 85 of the second metal part 74. The second positioning protrusion 81 indicates the relatively fixed position of the second metal part 74 relative to the fourth resin part 73.

[0112] The fourth resin part 73 has a seventh through hole 102 at a position corresponding to the fifth through hole 84. Opening 86 is the opening of the seventh through hole 107 on the contact surface between the fourth resin part 73 and the second metal part 74. The seventh through hole 102 is a through hole that penetrates both sides of the fourth resin part 73. A protrusion, described later, is fitted into the fifth through hole 84 and the seventh through hole 102, preventing the second metal part 74 and the fourth resin part 73 from wobbling in the direction of rotation. Since the seventh through hole 102 only requires the protrusion to be fitted, it can also be replaced by a non-penetrating hole.

[0113] The fourth resin part 73 has a second shaft hole 87. The second shaft hole 87 has an anti-rotation hole 88. A rotating shaft is inserted into the second shaft hole 87, and an anti-rotation handle that is vertically fixed to the rotating shaft is embedded in the anti-rotation hole 88. The rotating shaft is fixed to the fourth resin part 73, so that the rotation of the fourth resin part 73 is linked to the rotation of the rotating shaft. Alternatively, the rotating shaft can be configured with a non-circular cross-section and the anti-rotation hole 88 can be configured with a corresponding shape, thus transmitting the rotation of the rotating shaft to the fourth resin part 73 in the same way.

[0114] Next, let's explain the third resin part 72. Figure 13 The third figure illustrates the structure of an example of a second body of revolution.

[0115] The front side of the third resin section 72 has a stirring section 12. The back side of the third resin section 72 has a second recess 89 for receiving the second metal section 74. The second recess 89 is formed along the outer shape of the second metal section 74.

[0116] The rotation center of the third resin section 72 has a fourth shaft hole 93. A rotating shaft is inserted into the fourth shaft hole 93.

[0117] The second recess 89 has three third positioning protrusions 90. The third positioning protrusions 90 are positioned corresponding to the fifth through hole 84 of the second metal part 74 and the seventh through hole 102 of the fourth resin part 73, fitting into each hole. The third positioning protrusions 90, fitting into the fifth through hole 84 and the seventh through hole 102, prevent the third resin part 72 and the fourth resin part 73 from wobbling relative to the second metal part 74 in the rotational direction. The second rotating body 70 consists of three components rotating as a single unit. The cross-section of the third positioning protrusion 90 is circular, but not limited to this shape; it can also be polygonal or elliptical, etc., preferably a shape that is easy to process.

[0118] The side surface 91 of the third resin part 72 has a locking recess 92. The locking recess 92 is positioned corresponding to the locking protrusion 75. The locking protrusion 75 engages with the locking recess 92, fixing the third resin part 72 and the fourth resin part 73. A second metal part 74 is sandwiched and fixed between the third resin part 72 and the fourth resin part 73. The second rotating body 70 can be easily assembled and disassembled. The locking recess 92 is a contact part that abuts against the locking protrusion 75, and the locking protrusion 75 can also be referred to as a contact part that abuts against the locking recess 92.

[0119] Next, the back side of the second rotating body 70 will be described. Figure 14 This is a perspective view of the back side illustrating an example of the second rotating body. The second rotating body 70 has a second metal part 74 sandwiched between the third resin part 72 and the fourth resin part 73, thereby fitting and fixing the third resin part 72 and the fourth resin part 73 together.

[0120] A fourth resin portion 73 is disposed on the back side of the second rotating body 70. The back side of the fourth resin portion 73 has a groove for avoiding the control pin when the second rotating body 70 rotates. The first clearance groove 100 and the second clearance groove 101 of the fourth resin portion 73 are grooves through which the control pin passes to prevent it from abutting. To form this groove, the fourth resin portion 73 has a second central protrusion 97, a second inner peripheral protrusion 98, and a second outer peripheral protrusion 99.

[0121] The second inner circumferential protrusion 98 is disposed between the first clearance groove 100 and the second clearance groove 101. The second inner circumferential protrusion 98 is disposed upstream of the second rotating body 70 of the second push plate 77 in the rotational direction. The second inner circumferential protrusion 98 is adjacent to the second push plate 77 and resists the force when the second push plate 77 abuts against the coin, preventing deformation of the second push plate 77.

[0122] The second inner circumferential protrusion 98 is provided with a seventh through hole 102. The seventh through hole 102 is provided on the upstream side of the second rotating body 70 of the second push plate 77 in the rotation direction, and the third positioning protrusion 90 is fitted into the seventh through hole 102. When the coin is pushed by the second push plate 77, the upstream side of the second rotating body 70 of the second push plate 77 in the rotation direction is subjected to the greatest force. Therefore, the upstream side of the second rotating body 70 of the second push plate 77 in the rotation direction has a third positioning protrusion 90. The third resin part 72, the fourth resin part 73, and the second metal part 74 are securely connected by the third positioning protrusion 90 so that they do not shift from each other.

[0123] The second rotating body 70 of the second inner peripheral protrusion 98 has a second push plate hole 79 adjacent to the second inner peripheral protrusion 98 in the rotational direction downstream side. The second rotating body 70 of the second inner peripheral protrusion 98 has a first buffer portion 94 in the rotational center direction side. The second rotating body 70 of the second outer peripheral protrusion 99 has a third push plate hole 80 adjacent to the second outer peripheral protrusion 99 in the rotational direction downstream side. The second rotating body 70 of the second outer peripheral protrusion 99 has a second buffer portion 95 and a third buffer portion 96 on the rotational center direction side and the outer peripheral side of the third push plate hole 80 of the second outer peripheral protrusion 99.

[0124] The first buffer 94 prevents the coin from contacting the edge of the second push plate 77. Contact with the edge of the second push plate 77 could cause injury. When the second rotating body 70 rotates, the first buffer 94 covers the edge of the side where the coin initially contacts the second push plate 77. This part is prone to damaging the coin. In this example, although it covers only one edge of the second push plate 77, it could also cover both sides. The second buffer 95 and the third buffer 96 cover both edges of the third push plate 78, preventing the edge from contacting the coin. Because the first buffer 94, second buffer 95, and third buffer 96 do not forcefully push the coin, they can be formed using resin.

[0125] The opening of the second shaft hole 87 is wider than that of the third shaft hole 83. Therefore, the area around the third shaft hole 83 of the second metal part 74 is exposed through the second shaft hole 87. The second metal part 74 is fixed by abutting against the rotating shaft. By abutting and fixing the predetermined position of the rotating shaft against the area around the third shaft hole 83, the distance between the second metal part 74 and the substrate can be fixed. The predetermined positions are fixed by abutting against each other. An example has been shown in which a protrusion is provided in the third resin part 72 and a through hole is provided in the fourth resin part 73, but it is also possible to have a configuration in which a through hole is provided in the third resin part 72 and a protrusion is provided in the fourth resin part 73.

[0126] Next use Figures 15 to 18 To illustrate the third example of a rotating body. The third rotating body 110 can be applied to the rotating body of the aforementioned coin hopper. First, using... Figure 15 and Figure 18 To illustrate the shape of the third rotating body 110. Figure 15 This is a top view illustrating an example of a third body of revolution. Figure 15 This is a diagram showing the third rotating body 110 as viewed from directly above. Figure 18 This is a rear-side perspective view illustrating an example of a third rotating body.

[0127] The third rotating body 110 is equipped with three separation holes 6. The upper surface of the third rotating body 110 has stirring protrusions 71 extending radially from the stirring part 12.

[0128] The third rotating body 110 includes: a fifth resin portion 111 on the upper surface side, a sixth resin portion 112 on the back side side, and a third metal portion 113 (described later) sandwiched therebetween. The fifth resin portion 111 has a second locking recess 115, which engages with a second locking protrusion 114 on the sixth resin portion 112, thereby fixing the fifth resin portion 111 and the sixth resin portion 112. The third rotating body 110 is easy to assemble and can also be disassembled.

[0129] The second locking recess 115 is disposed on the outer peripheral side of the fifth resin part 111, between adjacent separation holes 6 and clamping the stirring protrusion 71.

[0130] A fourth pusher plate 116 and a fifth pusher plate 117 protrude from the predetermined position of the sixth resin section 112 toward the reverse side, pushing the coin.

[0131] The fifth resin portion 111 has a fourth positioning protrusion 119, which fits into the through holes of the third metal portion 113 and the sixth resin portion 112 (described later). At least one fourth positioning protrusion 119 is disposed on the upstream side of the third rotating body 110 in the rotational direction of each fourth pusher piece 116, up to the separation hole 6. The fourth positioning protrusion 119 is embedded in the through hole, and the fifth resin portion 111, the sixth resin portion 112, and the third metal portion 113 (described later) are prevented from wobbling relative to each other in the rotational direction by the fourth positioning protrusion 119. Furthermore, the fourth pusher piece 116 is supported by the sixth resin portion 112 on the upstream side of the third rotating body 110 in the rotational direction. The fourth pusher piece 116 receives force when pushing the coin, but is prevented from bending.

[0132] A rotating shaft is inserted into the sixth shaft hole 122 of the sixth resin part 112, and the sixth resin part 112 is fixed on the rotating shaft.

[0133] It includes: a fourth positioning protrusion 119 disposed at a position corresponding to the fourth push plate 116; and another fourth positioning protrusion 119 located between the rotation centers. The fifth resin part 111, the sixth resin part 112, and the third metal part 113 (described later) are prevented from wobbling relative to each other by the fourth positioning protrusions 119. The three components of the third rotating body 110 rotate as a single unit.

[0134] Next, the interior of the third rotating body 110 will be explained. Figure 16 This is the first diagram illustrating the structure of an example of the third rotating body. It is a perspective view showing the fifth resin part 111 and the third metal part 113 fixed together.

[0135] The fifth resin portion 111 has a recess on its back side for receiving the third metal portion 113. The recess has a fourth positioning protrusion 119. In addition, the recess has a second locking recess 115.

[0136] The third metal part 113 has a fifth shaft hole 118 at its rotation center. A rotating shaft is inserted and fixed into the fifth shaft hole 118. Arms extend radially from the fifth shaft hole 118 in three directions at equal angles. The third metal part 113 has a through hole into which a fourth positioning protrusion 119 fits. The front end of the third metal part 113 has a fourth push plate 116 and a fifth push plate 117.

[0137] Secondly, the interior of the third rotating body 110 will be described from other directions. Figure 17 This is the second figure illustrating the structure of an example of the third rotating body. It is a perspective view showing the sixth resin part 112 and the third metal part 113 fixed together.

[0138] The sixth resin section 112 includes a fourth pusher hole 120 through which the fourth pusher 116 of the third metal section 113 is inserted. The fourth pusher 116 is inserted through the fourth pusher hole 120 and protrudes toward the back side of the sixth resin section 112. A fifth pusher 117 is disposed along the outer peripheral edge of the sixth resin section 112 and protrudes toward the back side of the sixth resin section 112.

[0139] The sixth resin part 112 has a second locking protrusion 114. The second locking protrusion 114 is a snap-fit, engaging with the second locking recess 115 and securing the fifth resin part 111 and the sixth resin part 112. The second locking protrusion 114 and the second locking recess 115 have abutting portions that abut against each other. In addition, the third metal part 113 has an eighth through hole 121 at a position corresponding to the fourth positioning protrusion 119.

[0140] Next use Figure 19 and Figure 20 To illustrate the fourth example of a rotating body, the fourth rotating body 140 can be applied to the rotating body of the aforementioned coin hopper. The fourth rotating body 140 is an example where the push plate is not a single piece but is segmented and configured in each separation hole. Figure 19 This is the first diagram illustrating the structure of an example of a fourth rotating body. Figure 19 Showing an example of a split pusher piece. Figure 20 This is the second diagram illustrating the structure of an example of a fourth rotating body. Figure 20 This shows an example of a rotating body in which the segmented push pieces are fixed in place.

[0141] The fourth metal part 130 is to Figure 16 and Figure 17The third metal portion 113, as described, is formed by cutting out the portion including the fourth pusher piece 116, the fifth pusher piece 117, and the eighth through hole 121. The fourth metal portion 130 is formed by bending sheet metal to create the fourth pusher piece 116 and the fifth pusher piece 117, and by opening holes in the sheet metal to form the eighth through hole 121. Having multiple pusher pieces and miniaturizing them saves material. However, because multiple parts need to be assembled, the manufacturing process becomes more complex.

[0142] The fourth rotating body 140 clamps the fourth metal part 130 between the seventh resin part 141 and the eighth resin part 142. In addition, the fourth push plate 116 and the fifth push plate protrude from the back side of the fourth rotating body 140.

[0143] The fourth rotating body 140 has a center of rotation with Figure 16 and Figure 17 The sixth shaft hole 122 described is the same hole. The fourth rotating body 140 has a rotating shaft inserted through the sixth shaft hole 122 and is fixed to the rotating shaft.

[0144] The seventh resin part 141 is provided with a recess in the fourth metal part 130 that houses the seventh resin part 141, and is similar to... Figure 16 and Figure 17 The fourth positioning protrusion 119 described herein is the same as the previous one. When the fourth metal part 130 is housed in the recess, the fourth positioning protrusion 119 fits into the eighth through hole 121. The fourth metal part 130 is prevented from wobbling in the rotational direction of the fourth rotating body 140 by the fourth positioning protrusion 119.

[0145] The eighth resin section 142 is equipped with in four places with Figure 16 and Figure 17 The second locking protrusion 114 and the second locking recess 115 described herein are the same locking protrusions and locking recesses. The seventh resin portion 141 has a locking recess at a position corresponding to the second locking protrusion 114. By hooking the second locking protrusion 114 into the locking recess, the seventh resin portion 141 and the eighth resin portion 142 clamp the fourth metal portion 130 in the middle and fix it in place.
