Description

The present invention relates to a coin hopper that sends out coins stored in a container one by one, and a coin processing device equipped with the coin hopper.

A coin hopper is known that ejects coins one by one from a coin container in which a plurality of coins are stored. The coin hopper can eject coins one by one and count the number of coins ejected. Coin processing devices such as automatic change machines are equipped with a coin hopper for each denomination. For example, change data is output from a host device such as a POS system to a coin processing device. The change data includes data on the number of discharged sheets for each denomination. When the coin processing device inputs change data, it drives a coin hopper corresponding to the denomination included in the change data and ejects a specified number of coins. The discharged coins are collected at the receiving port and handed to the user.

The coin hopper is equipped with a container for storing coins and a rotating disk with an opening for coins one by one. For example, Japanese Patent Application Laid-Open No. 2013-250777 describes a coin hopper that ejects coins in a container one by one. When the coin in the container is charged, the coin hopper may have a problem when the coin is ejected. Therefore, the coin hopper is provided with a conductive path from the inside of the container to the outside of the housing. The coin hopper releases static electricity charged on the coin through a conductive path.

Further, a coin processing device equipped with a coin hopper is known. For example, the coin processing apparatus described in Japanese Patent Application Laid-Open No. 2017-151818 separates and sends out a plurality of coins inserted from the insertion slot one by one, and then sets the denomination of the coins to be conveyed one by one. It includes a step of identifying, and then a step of storing the identified coins for each denomination.

In the process of separating and sending out a plurality of coins inserted from the insertion slot one by one, an inclined base and a disk rotating on the base are used. Below the disc, a storage container for storing coins is arranged. For example, the storage container is arranged so as to cover about half of the lower part of the disk. The inserted multiple coins are temporarily stored in the storage container. Rotate the disc and pick up the coins in the storage container one by one. The disc is provided with a recess for one coin. When the concave portion of the rotating disk passes through the storage container, only one coin accumulated in the storage container enters the concave portion and is conveyed. Above the disc, a mechanism for delivering coins to the next process is provided. The coin is transported above the disc and delivered to the next process. In the next step, the denomination of the delivered coin is identified. The denomination of a coin is identified by multiple sensors that detect characteristics such as the size and material of the coin.

In the coin processing device, the coin is further handed over to the next process after the coin is identified. In the next step, the coins are carried by the belt. Slides are arranged for each denomination in the middle of the coin transport path by the belt. Each slide is connected to a coin hopper arranged for each denomination. The coin whose denomination is identified is dropped on the slide of the corresponding denomination during transportation. The coins dropped on the slide slide down to the storage container of the coin hopper for each denomination and are stored there.

The coin hopper can eject coins one by one. For example, the automatic change machine calculates the denomination and the number of coins to be ejected according to the amount of change, controls the coin hopper corresponding to each denomination, and ejects coins according to the amount of change.

Japanese Unexamined Patent Publication No. 2013-250777 Japanese Unexamined Patent Publication No. 2017-151818

A plurality of coins are stored in the containment vessel for storing coins in the coin hopper. The coins stored in the containment vessel are agitated as the disc rotates. Static electricity is generated by contact between coins, coins and containment vessels, coins and discs, coins and bases, and so on. When ejecting a charged coin, an electric discharge occurs between the coin and an electronic component such as a sensor or a connector. As a result, the charged coin causes a malfunction such as a failure of electronic parts and a false detection of a sensor. In addition, a coin processing device equipped with a coin hopper causes problems such as a shortage of discharged coins and overpayment.

Further, when the grounding electrode is arranged in the containment vessel, there is a problem that the coins do not come into contact with the electrodes when the number of coins in the containment vessel is small.

The present invention provides a coin hopper and a coin processing device capable of suitably eliminating static electricity in a coin container of a coin hopper, preventing problems such as false detection and failure of a sensor, and appropriately discharging coins.

The coin hopper of the present invention is arranged above a resin storage container for storing coins and a flat resin base, and is fixed to the rotating body and the rotating body for separating the coins one by one. The conductive rotating body shaft, which is the rotating body shaft, a drive mechanism for connecting the motor for driving the rotating body shaft and the rotating body shaft at a predetermined gear ratio, and the rotating body shaft are rotatably supported. In a coin hopper having a support portion, a drive mechanism, and a case for accommodating the support portion inside, the rotating body is rotated, and the coins stored in the storage container are discharged one by one. The case is provided with a bottom plate on the side facing the base, and a contact portion that contacts terminals arranged outside the case is arranged so as to be exposed to the outside from the bottom plate of the case. It is conductive with the rotating body shaft, and the contact portion is characterized by being conductive to the coin stored in the storage container via the rotating body shaft.

The coin processing device of the present invention includes the above-mentioned coin hopper, a mounting table on which a plurality of the coin hoppers are arranged, a coin receiving unit that receives and collects the coins discharged from each of the arranged coin hoppers. In the coin processing apparatus having the above-mentioned coin processing apparatus, a ground terminal for contacting the contact portion of the coin hopper is arranged on the above-mentioned pedestal, and by placing the coin hopper on the above-mentioned pedestal, the earth terminal is placed on the contact portion. Is in contact with the coin, and the charged coin in the storage container is released from the ground terminal.

According to the present invention, it is possible to provide a coin hopper and a coin processing device that can suitably eliminate static electricity even if the coin in the containment vessel is charged and can prevent a malfunction or failure of the coin hopper.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Each figure is merely schematically shown to the extent that the present invention can be fully understood. Therefore, the present invention is not limited to the illustrated examples. Further, in each figure, common components and similar components are designated by the same reference numerals, and duplicate description thereof will be omitted.

FIG. 1 is a perspective view of the appearance of the coin processing device. The coin processing device 1 separates the inserted coins one by one, identifies the denomination, stores each denomination in the coin hopper, and discharges the desired denomination and the number of coins. The coin processing device 1 is, for example, an automatic change machine, an automatic change machine, or the like. The coin processing device 1 is covered with a substantially cubic outer case. The coin processing device 1 is provided with a slot 2 for inserting coins and a tray 3 for receiving coins to be paid out.

The opening of the insertion slot 2 for inserting coins is arranged on the front side of the upper surface of the outer case. A tray 3 for receiving coins to be paid out is arranged on the front surface of the outer case. A withdrawal port 4 penetrating the inside and outside of the coin processing device 1 is provided at a position corresponding to the tray 3. The tray 3 receives the coins paid out through the withdrawal port 4. A display device 5 is arranged next to the slot 2. The display device 5 displays the status of the coin processing device 1, the deposit amount, the withdrawal amount, the guidance, and the like. A device for separating, identifying, storing, and paying out inserted coins is stored in an outer case.

For example, the coin processing device 1 is a device for depositing and withdrawing coins such as an automatic change machine and an automatic money changer. A coin is inserted into the insertion slot 2. A control unit (not shown) acquires the denomination and the number of inserted coins, and grasps the inserted amount. Whether or not to pay out is calculated, and if there is a payout, the denomination and number of coins to be paid out are calculated, and the coin hopper is controlled to eject coins. The ejected coins are sent to the tray 3.

Next, the configuration of the coin processing device 1 will be described. FIG. 2 is a diagram illustrating a configuration of a coin processing device. Commonly used coins are made up of multiple denominations. Coins have different elements such as size, material, and design for each denomination.

The coin processing device 1 separates the inserted coins one by one, identifies the denomination for each divided coin, and stores the identified coins for each denomination. Further, the coin processing device 1 reuses the coins stored for each denomination for payout.

The coin processing device 1 is roughly divided into three parts. The three parts are a separation unit 6 that divides and sends out the inserted coins one by one, an identification unit 8 that identifies the denomination of the coin, and a distribution unit 9 that stores the coins separately for each denomination.

Coins of a plurality of denominations are inserted into the insertion slot 2 of the coin processing device 1 in a mixed state. The coin 10 inserted in the insertion slot 2 passes through the coin passage 11 and is stored in the storage container 12. The slot 2, the coin passage 11, and the storage container 12 are shown by broken lines in FIG.

A disc 15 and a wheel 21 for carrying the coin 10 are arranged on the upper surface of the holding base 13. The storage container 12 is arranged on the lower side of the disk 15 in the vertical direction. The storage container 12 is provided with a bottom having a shape along the outer circumference of the disk 15. The storage container 12 covers about one-third from the lower half of the disk 15. The coin 10 is stored in the portion surrounded by the disk 15 and the storage container 12.

Further, the disc 15 is provided with disc recesses 16 for holding the coin 10 at three places. The coin 10 enters the disk recess 16 and is conveyed. Further, the area on the outer peripheral side of the disk 15 is open. The coin 10 is delivered from the separation section 6 to the identification section 8 at the delivery section 7.

The holding base 13 and the disk 15 are arranged so as to be inclined with respect to the horizontal direction. In the storage container 12, the coin 10 leans against the disk 15. The coin 10 in the storage container 12 moves relative to the disk 15 as the disk 15 rotates. The coin 10 enters the disk recess 16 that passes through the storage container 12.

The side surface of the coin 10 that has entered the disc recess 16 abuts on the inner wall of the disc recess 16. Since the holding base 13 and the disc 15 are arranged so as to take an oblique posture with respect to the horizontal direction, the coin 10 can be held in the disc recess 16 of the disc 15. The tilt angle of the holding base 13 is within the range of 30 degrees to 80 degrees. 40 degrees to 50 degrees is more preferable. If the tilt angle is small, unnecessary coins 10 cannot be slid off from the disc recess 16, and if the tilt angle is large, it becomes difficult for coins to enter the disc recess 16. Further, the height of the inner wall of the disc recess 16 is set to be lower than the thickness of the coin 10 so that only one coin 10 can be inserted. Further, in consideration of the diameter of the minimum size coin 10, the disc recess 16 is made so that only one minimum size coin 10 can be inserted. Further, only one coin 10 having the maximum size can be inserted in the disk recess 16.

The coin 10 is held in a posture in which the front surface or the back surface of the coin 10 faces the flat bottom surface of the disk recess 16. Further, since the inner wall of the disc recess 16 is interrupted in the region on the outer peripheral side of the disc 15, the coin 10 is passed to the next process through the interrupted region. A guide wall for guiding the coin 10 in the disk rotation direction is arranged on the outside of the outer circumference of the disk 15. The coin 10 is conveyed with its side surface in contact with the guide wall and the inner wall of the disc recess 16.

The disk 15 rotates about the disk rotation axis 14 in the disk rotation direction 17 indicated by the arrow. The disk recess 16 picks up coins 10 stored in the storage container 12 one by one. Since the disc 15 is arranged diagonally with respect to the horizontal direction, the coin 10 in the storage container 12 leans against the disc 15. The coin 10 leaning against the disc 15 easily enters the disc recess 16.

The coin 10 is delivered at a position above the separation unit 6 and below the identification unit 8. Although FIG. 2 shows an example in which the identification unit 8 and the separation unit 6 are arranged vertically, the identification unit 8 and the separation unit 6 can also be arranged on the left and right sides. The disc 15 can convey the coins 10 one by one to the delivery unit 7, and deliver the coins 10 to the identification unit 8 which is the next process.

The wheel 21 rotates about the wheel rotation axis 20 in the wheel rotation direction 22 indicated by the arrow. The wheel 21 rotates in conjunction with the rotation of the disc 15. The coin 10 sent out from the separating portion 6 has its side surface abutted against the wheel 21, is pushed by the wheel 21, and slides on the holding base 13. The holding base 13 is a flat flat surface. An identification sensor 19 for detecting characteristics such as the size and material of the coin 10 is arranged in the identification unit 8. The feature of the coin 10 moving on the holding base 13 is detected by the identification sensor 19, and the denomination of the coin 10 is identified by a control unit (not shown). Since the coins 10 are separated and conveyed one by one by the wheel 21, the identification sensor 19 can suitably detect the characteristics of the coins 10 one by one. The coin 10 is pushed by the wheel 21 and moves along the guide portion 18 with the front surface or the back surface in contact with the holding base 13 and the side surface in contact with the guide portion 18. The coin 10 whose denomination is identified by the identification unit 8 is handed over to the distribution unit 9 in the next process.

In the distribution unit 9, a rail 25 for guiding the coin 10 is arranged. The coin 10 is passed from the identification unit 8 to the rail 25 of the distribution unit 9. The coin 10 is conveyed along the rail 25. The conveyor belt 24 is arranged along the rail 25. Conveying pin rollers 23 are arranged at equal intervals on the transport belt 24. One coin 10 is inserted between the transport pin rollers 23. The transport pin roller 23 pushes the coins 10 one by one and transports the coins 10 along the rail 25. The transport pin roller 23 can also be said to be a pushing body that pushes and transports the coin 10. The conveyor belt 24 is an endless belt and rotates in conjunction with the disc 15 and the wheel 21 in the conveyor belt rotation direction 26 indicated by the arrow.

Along the rail 25, a first slider 27, a second slider 29, a third slider 31, a fourth slider 33, a fifth slider 35, a sixth slider 37, and a seventh slider 39 are arranged. These sliders are connected to a coin hopper or container of a predetermined denomination. The coin 10 identified by the identification unit 8 is dropped on the slider of the corresponding denomination and stored in the coin hopper or container of the corresponding denomination.

The first slider 27 is connected to the first coin hopper 28. The second slider 29 is connected to the second coin hopper 30. The third slider 31 is connected to the third coin hopper 32. The fourth slider 33 is connected to the fourth coin hopper 34. The fifth slider 35 is connected to the fifth coin hopper 36. The sixth slider 37 is connected to the sixth coin hopper 38. Further, the seventh slider 39 is connected to the overflow container 40.

The eighth slider 41 guides the coin 10 to the discharge belt 42. The coin 10 whose denomination cannot be identified and the unusable coin 10 are guided onto the discharge belt 42 and discharged to the tray 3.

The amount of coins 10 that can be stored in the coin hopper is predetermined. When the amount of coins 10 stored in the coin hopper is full, no more coins 10 can be stored in the coin hopper. If the coin 10 cannot be stored in the coin hopper, the unstorable coin 10 is stored in the overflow container 40. If the coin 10 is paid out from the full coin hopper, the coin hopper can store the coin 10 again. By storing the coins 10 that cannot be stored in the coin hopper in the overflow container 40, the number of maintenance of the coin processing device 1 can be reduced. The coin processing device 1 is operated efficiently. Since the overflow container 40 may be a container that does not have a function of discharging coins, or may be a coin hopper, as long as it can store coins 10.

Each coin hopper is arranged in two rows along the discharge belt 42. By driving the discharge belt 42, the coins 10 discharged from each coin hopper are guided to the withdrawal port 4 and collected in the tray 3. That is, the discharge belt 42 can be said to be a coin receiving unit that receives and collects coins 10 discharged from a plurality of coin hoppers. The coin 10 inserted in the slot 2 is reused as a coin 10 for payout. Further, the coin hopper is electrically connected to the coin processing device 1 in order to release the static electricity charged in the coin 10 stored in the coin hopper. By placing the coin hopper on a mounting table described later provided in the coin processing device 1, the coin processing device 1 and the coin hopper are electrically connected to each other.

The disk 15 rotates about the disk rotation axis 14. The wheel 21 rotates about the wheel rotation shaft 20. The disc rotation shaft 14 and the wheel rotation shaft 20 are rotated by a motor (not shown). The motor and the disc rotation shaft 14 are connected by a train wheel (not shown). Further, the motor and the wheel rotation shaft 20 are connected by a train wheel (not shown). The train wheel decelerates the number of revolutions of the motor at a predetermined ratio. The motor and train wheel form a drive unit that rotates the disc 15 and the wheel 21.

The coin 10 is slid from the separation portion 6 to the identification portion 8 via the delivery portion 7. In the movement path of the coin 10, each has a flat surface and is arranged without a step.

The disk 15 is provided with a plurality of disk recesses 16 at equal angles about the disk rotation shaft 14. For example, it is provided at three places at intervals of 120 degrees. A lever 43 is arranged in each disk recess 16. When the coin 10 is carried to the delivery unit 7, the lever 43 operates. The lever 43 pushes out the coin 10 in the outer peripheral direction of the disc 15, that is, in the direction of the identification portion 8. The coin 10 is delivered from the separation unit 6 to the identification unit 8.

The coin 10 is pushed out from the disc 15 of the separation unit 6 and picked up by the wheel 21 of the identification unit 8.

Receiving bodies are radially arranged on the wheel 21 at intervals of 120 degrees around the wheel rotation axis 20. A coin 10 is inserted between each receiver, and the coin 10 is pushed by the push wall on the side surface of the receiver. The coin 10 slides on the holding base 13. The wheel 21 rotates in conjunction with the disc 15, and the direction of rotation is opposite.

The identification unit 8 detects the coins 10 moving along the guide unit 18 one by one by the identification sensor 19, and identifies the denomination. The guide wall 18 is arranged in a straight line. The coin 10 moves linearly along the guide portion 18.

The coin 10 is pushed by the wheel 21 and passed from the identification unit 8 to the distribution unit 9. The coin 10 pushed by the wheel 21 is passed onto the rail 25. The wheel 21 and the transport belt 24 rotate in conjunction with each other. The transport pin roller 23 is arranged on the transport belt 24 so that one coin 10 can be inserted between the adjacent transport pin rollers 23.

The coin 10 moving along the rail 25 is dropped on the slider corresponding to the denomination. The coin hopper stores coins 10 of the same denomination.

Next, the main part of the coin processing device 1 will be described. FIG. 3 is a perspective view of a main part of the coin processing device.

In the separation unit 6, the inserted coin 10 is stored in the storage container 12. A plurality of coins 10 can be temporarily stored in the storage container 12. The stored coins 10 are conveyed one by one by the disk 15. When the coin 10 is conveyed to the position of the delivery unit 7, the lever 43 operates to push the coin 10 toward the identification unit 8. The extruded coin 10 passes through the delivery section 7 and enters between the receivers of the wheel 21. FIG. 3 illustrates a state in which the sensor cover covering the identification unit 8 is open. Under normal use, the sensor cover is closed.

In the identification unit 8, the coin 10 is pushed by the wheel 21. The coin 10 moves on the holding base 13 one by one. The guide portion 18 is arranged on the lower side of the identification portion 8. The guide portion 18 is diagonally arranged so that the traveling direction of the coin 10 is higher in the vertical direction. The guide portion 18 is a part of a guide wall arranged on the outside of the outer circumference of the wheel 21. The guide unit 18 is a guide wall arranged in a straight line in order to detect the coin 10 under certain conditions. The wheel 21 pushes the coin 10. The coin 10 slides on the holding base 13 along the guide portion 18. Since the holding base 13 is arranged so as to be inclined with respect to the horizontal direction, the side surface of the coin 10 is in contact with the guide wall, and the front surface or the back surface is in contact with the holding base 13. A force is applied downward to the coin 10 by gravity. The wheel 21 that has passed the lowest point carries the coin 10 upward against gravity. The coin 10 is conveyed in contact with the guide portion 18. The outer circumference of the coin 10 slides or rolls while in contact with the guide portion 18. The coin 10 passes through the detection area of the identification sensor 19 under certain conditions.

The coin 10 whose denomination is identified by the identification sensor 19 is passed from the identification unit 8 to the distribution unit 9. One coin 10 is inserted between the transport pin rollers 23. The coin 10 is pushed and transported by the transport pin roller 23. The coins 10 separated one by one by the wheel 21 in the identification unit 8 are separated and conveyed one by one by the transfer pin roller 23 in the distribution unit 9.

The coin 10 identified by the identification unit 8 is dropped by any of the sliders of the distribution unit 9 during transportation.

The first bar 44, the second bar 45, the third bar 46, and the fourth bar 47 are controlled by a control circuit (not shown) to change the course of the coin 10. The first bar 44 puts the coin 10 in a state of either dropping it on the first slider 27, dropping it on the fourth slider 33, or letting it pass. The second bar 45 puts the coin 10 in a state of either dropping it on the second slider 29, dropping it on the fifth slider 35, or letting it pass. The third bar 46 is in a state where the coin 10 is either dropped on the third slider 31, dropped on the sixth slider 37, or passed. The fourth bar 47 either drops the coin 10 onto the eighth slider 41 or allows it to pass through. The coin 10 that has passed through all the sliders falls to the seventh slider. Based on the denomination of the result identified by the identification unit 8, the coin 10 falls on any of the sliders and is guided to a predetermined coin hopper or the like.

FIG. 4 is a diagram illustrating an arrangement example of a coin hopper mounted on the coin processing device. The first mounting table 50 and the second mounting table 51 on which the coin hopper is placed are arranged so as to sandwich the discharge belt 42. The coin hoppers are arranged in rows on both sides of the discharge belt 42.

The first coin hopper 28, the second coin hopper 30, and the third coin hopper 32 are placed in a row on the first mounting table 50. A fourth coin hopper 34, a fifth coin hopper 36, and a sixth coin hopper 38 are placed in a row on the second mounting table 51.

The first discharge port 53 is an opening for discharging the coin 10 of the first coin hopper 28. The second discharge port 54 is an opening for discharging the coin 10 of the second coin hopper 30. The third discharge port 55 is an opening for discharging the coin 10 of the third coin hopper 32. The first discharge port 53, the second discharge port 54, and the third discharge port 55 are arranged on the discharge belt 42 side. The discharge belt 42 is a belt hung around a pulley 52 and a drive pulley (not shown). By driving the drive pulley with a motor (not shown), the discharge belt 42 is rotated, and the coin 10 discharged on the discharge belt 42 is guided to the tray 3 via the withdrawal port 4.

The coin hopper is optimized according to the denomination. The first mounting table 50 mounts a plurality of coin hoppers. Four coin hoppers are mounted on the first mounting table 50. The same applies to the second mounting table. The positions of the coin hoppers mounted on the first mounting table 50 and the second mounting table 51 are predetermined according to the denomination. Further, the first mounting table 50 and the second mounting table 51 are provided with identification protrusions for preventing the coin hopper from being set at an erroneous position. The shape of the identification protrusion is a predetermined shape according to the denomination. The coin hopper is provided with a recess corresponding to the identification protrusion according to the denomination. If the identification protrusion and the recess do not match, the coin hopper cannot be set on the first mounting table 50. The same applies to the second mounting table 51.

The first mounting table 50 and the second mounting table 51 make it possible to easily arrange coin hoppers of denominations corresponding to predetermined positions.

Next, the coin hopper will be described. FIG. 5 is a perspective view of the coin hopper. The coin hopper uses the one whose setting is optimized according to the denomination, but the basic configuration is the same for all denominations.

A coin hopper is a device that separates and ejects a plurality of coins one by one. The coin hopper is roughly divided into a main body 60 and a coin containment vessel 61. The coin containment vessel 61 can be attached to and detached from the main body 60. The coin containment vessel 61 is open at a portion facing a rotating body, which will be described later. The connection portion 64 is an outer peripheral portion of the opening. A plurality of coins 10 of a predetermined denomination can be stored in the coin containment vessel 61. The coin 10 in the coin containment vessel 61 is deposited on the rotating body. The main body 60 is covered with a case, and a drive mechanism is arranged inside. The main body 60 is provided with a mechanism for separating and discharging a plurality of coins 10 one by one by using a rotating body described later.

The stirring rod 65 is a metal rod fixed to the coin containment vessel 61. The stirring rod 65 is fixed to the coin containment vessel 61, and a spring is arranged on the root side. The tip side of the stirring rod 65 moves in various directions due to the elasticity of the spring on the root side. The coin 10 in the coin containment vessel 61 moves by rotating a rotating body described later. Since the coin 10 in the coin containment vessel 61 can be agitated by the stirring rod 65, it is possible to prevent the coins 10 from overlapping and forming a bridge shape. The motor 69 drives a rotating body.

The first support portion 66 and the second support portion 67 are provided on the side surface of the main body 60. The first support portion 66 and the second support portion 67 support the side surface of the coin containment vessel 61.

The payout port 62 for discharging the coin 10 is provided on one side of the main body 60. The side of the main body 60 where the payout port 62 is provided is referred to as a front side, and the opposite side is referred to as a back side. The coins 10 are ejected one by one from the payout port 62. The ejected coin 10 is detected by the payout sensor 63. By detecting the coin 10 with the payout sensor 63, it can be seen that the coin 10 has been paid out.

Guide grooves 68 are provided on both side surfaces of the main body 60. A groove is provided at a predetermined portion on the side surface of the main body 60 at a constant depth. That is, a guide groove 68 is provided on the side wall of the case of the main body 60. The guide groove 68 is used when the coin hopper is arranged at a predetermined position of the coin processing device.

FIG. 6 is a side view of the coin hopper.

The coin containment vessel 61 of the coin hopper includes a container inclined portion 74, and guides the coin 10 to a rotating body described later. The coin 10 is deposited on the lower side of the coin containment vessel 61.

A motor 69 is arranged on the back surface side of the upper surface of the main body 60. The motor shaft, which is the rotation shaft of the motor 69, is connected to a rotating body described later inside the main body 60 via a train wheel (not shown). The train wheel connects the motor shaft, which is the rotation shaft of the motor 69, and the rotation shaft of the rotating body with a predetermined gear ratio.

A second support protrusion 73 is provided on the side surface of the coin containment vessel 61. The second support protrusion 73 fits into the hole provided in the second support portion 67. Further, the first support protrusion is provided on the opposite side. The first support protrusion fits into the hole provided in the first support portion 66 (FIG. 5). Both sides of the coin containment vessel 61 are supported by the main body 60.

A step portion 75 is provided on the side surface of the main body 60. A guide groove 68 is formed on the side surface of the main body 60 by the step portion 75. The step portion 75 is provided in parallel upward from the bottom plate 76 side of the main body 60. For example, a protrusion corresponding to the guide groove 68 is provided at the mounting position of the mounting table of the coin hopper. By aligning the guide groove 68 with the protrusion provided on the mounting table, the coin hopper can be easily set at a predetermined position on the mounting table. Guide grooves 68 are provided on both side surfaces of the main body 60.

The rotating body shaft 70 protrudes from the bottom plate 76 of the main body 60. The rotating body shaft 70 is a rotating body to which a rotating body described later is fixed and passes through the rotation center of the rotating body. The gear at the final stage of the train wheel connected to the motor 69 is fixed to the rotating body shaft 70.

Support legs 71 are arranged on the bottom plate 76. The support legs 71 project from the bottom plate 76. In the side view, the rotating body shaft 70 is arranged between the support leg 71 and the front end portion 72 of the bottom plate 76. Further, in the side view, the guide groove 68 is arranged between the support leg 71 and the front end portion 72. When the coin hopper is placed on a flat surface, the front end portion 72 and the support legs 71 are in contact with the flat surface, and the rotating body shaft 70 is separated from the flat surface. When the coin hopper is placed, it is possible to prevent an object from coming into contact with the rotating body shaft 70. Further, the distance from the front end portion 72 to the rotating body shaft 70 is longer than the distance from the rotating body shaft 70 to the support leg 71. That is, the rotating body shaft 70 is biased toward the support leg 71 side with respect to the front end portion 72. In order to prevent the rotating body shaft 70 from hitting an object, it is preferable to arrange the support legs 71 near the rotating body shaft 70. Further, the support legs 71 may be provided at three or more places so as to surround the rotating body shaft 70, or a frame instead of the support legs 71 may be provided.

In the side view, the rotating body shaft 70 is arranged between the two stepped portions 75 of the guide groove 68. The guide groove 68 is arranged along the direction perpendicular to the bottom plate 76. When the coin hopper is set on the mounting table, the coin hopper moves from top to bottom along the guide groove 68. That is, the coin hopper moves from top to bottom along the extending direction of the step portion 75. The tip of the rotating body shaft 70 also moves from top to bottom.

FIG. 7 is a perspective view of the main part of the coin hopper. It is a perspective view of the main body 60 of a coin hopper.

A hopper base 81 is arranged on the upper surface side of the main body 60, and a rotating body 80 is arranged on the hopper base 81. The rotating body 80 is fixed to the rotating body shaft 70 (FIG. 6) by a screw 77. The screw 77 is a conductive metal screw. The rotating body 80 is provided with four rotating body recesses 82 for inserting the coin 10.

The hopper base 81 is provided with a movement control pin (not shown). When the rotating body 80 is rotated with the coin 10 in the rotating body recess 82, the coin 10 is pushed by the pressing wall 78, and the coin 10 moves together with the rotating body 80. When the coin 10 comes into contact with the movement control pin, the moving direction of the coin 10 changes, and the coin 10 is ejected from the payout port 62. The rotating body 80 is provided with a relief groove 79 in order to avoid the movement control pin. The rotating body 80 can rotate without hitting the movement control pin.

The payout sensor 63 detects the coin 10 discharged from the payout port 62. By counting the detection results, it is possible to grasp how many coins 10 have been ejected from the payout port 62.

The fixing portion 83 supports the coin containment vessel 61 (FIG. 5) together with the first support portion 66 and the second support portion 67. The fixing portion 83 is provided with a screw to fix the coin containment vessel 61 (FIG. 5) to the main body 60. The coin containment vessel 61 (FIG. 5) can be detachably fixed to the main body 60.

The rotation axis of the motor 69 is perpendicular to the hopper base 81. It is arranged in parallel with the rotation axis of the rotating body 80. That is, the rotation axis of the motor 69 is parallel to the rotation body axis 70 (FIG. 6). The rotating shafts of the motors 69 arranged in parallel and the rotating body shaft 70 (FIG. 6) are connected by a train wheel (not shown). The train wheel transmits the driving force of the motor 69 to the rotating body shaft 70 (FIG. 6).

The tip end side of the rotation shaft of the motor 69 is connected to a train wheel (not shown) arranged inside the main body 60. An exterior case containing the coils and magnets of the motor 69 is arranged outside the main body 60. Since a part of the motor 69 is arranged outside the main body 60, the size of the main body 60 in the thickness direction can be reduced. Since the size of the main body 60 in the thickness direction can be reduced, the length of the rotating body shaft 70 (FIG. 6) can also be reduced. By shortening the axis of the rotating body 80, the influence of the force from the direction perpendicular to the axis can be reduced.

FIG. 8 is a perspective view from the back side of the coin hopper.

A positioning hole 86 is provided at the end of the bottom plate 76 on the payout port 62 side. An identification hole 87 is arranged inside the positioning hole 86. The positioning hole 86 is provided with a semi-circular convex portion in the radial direction in eight directions from the center. One of the convex portions in the eight directions is deeply recessed. The position of this depression indicates the corresponding denomination. A protrusion corresponding to the identification hole 87 is arranged on the table on which the coin hopper is placed, and a coin hopper of a predetermined denomination can be set at a predetermined position.

A first connector 84 is arranged at the opposite end of the bottom plate 76 on the payout port 62 side. The first connector 84 is a connector for connecting various signal lines and power supplies that control the operation of the coin hopper to an external device. The payout sensor 63 is wired by a cable 88 that fits into a cable groove 89 provided in the bottom plate 76. By fitting the cable 88 into the cable groove 89, the cable 88 does not come off from the cable groove 89 due to vibration. By making the opening of the cable groove 89 narrower than the bottom, the cable 88 can be prevented from coming off from the cable groove 89. The cable 88 is a cable in which a plurality of wires are combined into one.

The payout sensor 63 and the first connector 84 are arranged at the respective ends in the longitudinal direction of the coin hopper. A drive mechanism for the rotating body 80 (FIG. 7) is arranged inside the main body 60. When the cable 88 comes into contact with the drive mechanism, disconnection or drive failure occurs. Therefore, it is necessary to provide a means for fixing the cable 88 or separating the cable 88 from the drive mechanism. However, when the means for preventing the contact between the cable 88 and the drive mechanism is provided, there are restrictions such as the arrangement position of the cable 88 and the communication position inside and outside the main body 60, and it may not be possible to wire in a short distance. Therefore, the cable 88 is arranged outside the main body 60 in which the cable 88 and the drive mechanism do not come into contact with each other. The first connector 84 is arranged at one end of the main body 60, and the payout sensor 63 is arranged at the other end. If both can be arranged in either one, the cable 88 can be easily arranged, which is preferable. If this is not possible, it is preferable to provide a groove on the outside of the main body 60 to arrange the cable 88.

The support legs 71 are provided in two places on the bottom plate 76. The rotating body shaft 70 is arranged at both ends of the front end portion 72 and at a position surrounded by the two support legs. The rotating body shaft 70 protruding from the bottom plate 76 is protected by the support legs 71. The rotating body shaft 70 is arranged substantially in the center of the coin hopper in the lateral direction. A groove edge portion 85 is provided on the bottom plate 76 side of the guide groove 68. A slope is formed on the groove edge portion 85 so that the groove of the guide groove 68 becomes deeper toward the bottom plate 76. When placing the coin hopper, it is easy to place.

FIG. 9 is a cross-sectional view of the coin hopper.

The coin containment vessel 61 can store a plurality of coins 10. The coin 10 is deposited on the rotating body 80. The rotating body 80 is rotated to convey the coin 10 contained in the rotating body recess 82. By rotating the rotating body 80, the pressing wall 78 on the inner circumference of the rotating body recess 82 comes into contact with the peripheral surface of the coin 10. The coin 10 moves with the rotation of the rotating body 80. The coin 10 slides on the hopper base 81.

Since the charged coin 10 may adversely affect the electronic components, it is necessary to release static electricity. When the hopper base 81 and the coin containment vessel 61 are made of resin, the static electricity of the coin 10 cannot be released to the ground from the hopper base 81 and the coin containment vessel 61.

The rotating body 80 is fixed to the rotating body shaft 70 by a screw 77. The rotating body shaft 70 is a metal shaft and is conductive. For example, a stainless steel shaft. Further, the screw 77 is also made of metal and is conductive. The tip of the rotating body shaft 70 protrudes from the bottom plate 76 of the main body 60. The tip of the rotating body shaft 70 includes a flat shaft bottom surface 98. The static electricity of the charged coin 10 can be transmitted to the bottom surface 98 of the shaft via the rotating body shaft 70. By contacting the terminal connected to the ground with the bottom surface 98 of the shaft, the static electricity of the coin 10 can be released. That is, the coin 10 conducts to the bottom surface 98 of the shaft.

The shaft bottom surface 98 is formed in a direction perpendicular to the axial direction of the rotating body shaft 70. For example, it is parallel to the flat surface of the hopper base 81. If the bottom surface 98 of the shaft is formed diagonally in the axial direction of the rotating body shaft 70, the tip becomes sharp and the terminal in contact with the bottom surface 98 of the shaft is damaged.

When the rotating body 80 is made of an insulating material such as resin, the static electricity of the coin 10 can be released via the screw 77 and the rotating body shaft 70. The coin 10 conducts to the bottom surface 98 of the shaft.

When the rotating body 80 is made of a conductive material such as metal, the static electricity of the coin 10 can be released via the rotating body 80 and the rotating body shaft 70. The coin 10 conducts to the bottom surface 98 of the shaft.

The rotating body shaft 70 is rotatably supported by a first sliding portion 92 arranged on the back surface side of the hopper base 81. The first sliding portion 92 uses a bearing or the like to support the rotating body shaft 70 while rotating it. Further, the rotating body shaft 70 is provided with a groove in the portion of the retaining ring 94, and the retaining ring 94 is fitted in the groove. The retaining ring 94 limits the axial movement of the rotating body shaft 70 and also limits the axial movement of the first sliding portion 92.

Further, the bottom plate 76 is provided with a through hole for exposing the rotating body shaft 70 to the outside. For example, the rotating body shaft 70 can be passed through the through hole and projected from the bottom plate 76. The rotating body shaft 70 is rotatably supported by a second sliding portion 93 including a bearing portion 91 arranged inside the bottom plate 76. The diameter of the rotating body shaft 70 is reduced at the portion of the bearing portion 91. The rotating body shaft 70 does not come off from the bottom plate 76 due to the step of the bearing portion 91. A through hole is provided in the central portion of the bearing portion 91. The tip of the rotating body shaft 70 is passed through the through hole of the bearing portion 91 and the through hole of the bottom plate 76, and is exposed to the outside from the bottom plate 76. That is, the tip of the rotating body shaft 70 is exposed to the outside from the through hole provided in the bottom plate 76. For example, static electricity can be released to the outside by bringing the tip of the rotating body shaft 70 exposed from the through hole into contact with the ground. The through hole of the bottom plate 76 is also referred to as a first through hole, and the through hole of the bearing portion 91 is also referred to as a second through hole. The tip of the rotating body shaft 70 passes through the first through hole and the second through hole and protrudes from the bottom plate 76.

A ground terminal is provided on the outside of the main body 60, and the bottom surface 98 of the shaft is brought into contact with the ground terminal. The static electricity of the charged coin 10 can be released from the bottom surface 98 of the shaft to the outside of the main body 60. However, since the rotating body shaft 70 and the external ground terminal are brought into contact with each other, a force is applied to the rotating body shaft 70 from the outside. Since an external force is applied to the rotating body shaft 70, the rotating body shaft 70 may be adversely affected by rotation. For example, uneven rotation, shaking of the shaft, and the like. Therefore, in order to reduce the shaking of the rotating body shaft 70, the first sliding portion 92 and the second sliding portion 93 are arranged apart from each other, and the rotating body shaft 70 is supported at at least two places. A drive gear 95 at the final stage of the train wheel is fixed to the rotating body shaft 70 between the first sliding portion 92 and the second sliding portion 93. By arranging the drive gear 95 in the final stage between the support portions, the drive force is transmitted while suppressing the influence of the external force.

Since the rotating body shaft 70 and the external ground terminal are brought into contact with each other, an external force is applied to the rotating body shaft 70 in the axial direction. By making the force from the ground terminal applied in the axial direction of the rotating body shaft 70 less than the total weight of the rotating body shaft 70 and the rotating body 80, the influence of the force from the axial direction of the rotating body shaft 70 is suppressed. The rotating body 80 can be rotated. It is possible to prevent the rotating body shaft 70 and the rotating body 80 from being lifted by the force from the ground terminal.

The rotating body shaft 70 is arranged at the center of the rotating body 80 in a top view. Since a plurality of coins 10 are deposited on the rotating body 80, a considerable load is applied to the rotating body 80. Since the rotating body 80 is rotated in that state, it is preferable that the position of the rotating body shaft 70 in the upper view is the position of the center of gravity or a position close to the center of gravity. If the rotating body shaft 70 is separated from the position of the center of gravity, the coin hopper tends to shake, which may cause vibration.

A drive gear 95 is fixed to the rotating body shaft 70. Further, the strength of the bottom plate 76 is increased by ribs 96 provided so as to project inside the main body 60 of the bottom plate 76. The rib 96 and the drive gear 95 do not come into contact with each other.

The cable groove 89 for accommodating the cable 88 forms an inner wall 97 of the cable groove protruding inside the main body 60. It is also a rib that improves the strength of the main body 60. Further, since the cable 88 can be separated to the outside by the cable groove inner wall 97, maintenance such as replacement of the cable 88 can be easily performed. Further, at the time of maintenance, it is not necessary to isolate the cable 88 so that it does not come into contact with other parts, so that the maintenance work can be reduced. Further, by reducing the number of wiring materials in the main body 60 as much as possible, assembly becomes easy and maintenance becomes easy.

FIG. 10 is a first example of a coin hopper grounding method. As an example, a case where a coin hopper is set on the first mounting table 50 will be described.

The first mounting table 50 includes a base portion 100 constituting the bottom surface and a frame portion 101 constituting the periphery. The coin hopper is set on the base 100 with the coin containment vessel 61 facing up and the main body 60 facing down.

The base 100 is provided with a ground groove 103 at a portion corresponding to the rotating body shaft 70 of the coin hopper. The base 100 is provided with a leg escape portion 102 at a portion corresponding to the support leg 71 of the coin hopper. The base 100 is provided with a recess in a portion corresponding to the rotating body shaft 70 and the support leg 71 of the coin hopper. Further, the base 100 is provided with a second connector 104 at a portion corresponding to the first connector 84 of the coin hopper. Further, the base 100 is provided with a positioning projection 109 and an identification projection 108 at a portion corresponding to the positioning hole 86 and the identification hole 87 of the coin hopper. The frame portion 101 is provided with a guide portion 90 at a portion corresponding to the step portion 75 of the coin hopper.

The base 100 is provided with protrusions and dents in a portion corresponding to the unevenness of the coin hopper, and when the coin hopper is mounted, the base 100 guides the coin hopper to a predetermined position, and the coin hopper after mounting also guides the coin hopper to a predetermined position. , Is configured to prevent rattling. When the coin hopper is placed on the first mounting table 50, the flat portion of the bottom plate 76 of the coin hopper comes into contact with the flat portion of the bottom surface of the base 100. The payout port 62 is arranged at a position higher than the edge of the frame portion 101 so as not to be an obstacle when ejecting coins.

The ground terminal 106 is connected to the ground via the ground line 107. A ground terminal 106 connected to the ground is arranged in the ground groove 103. When the coin hopper is set on the first mounting table 50, the bottom surface 98 of the shaft comes into contact with the surface of the ground terminal 106. The ground terminal 106 is located at the ground terminal position 105 when the rotating body shaft 70 is not in contact, which is indicated by a dotted line. When the coin hopper is set on the first mounting table 50, the bottom surface 98 of the shaft comes into contact with the ground terminal 106 and pushes it down. The pushing-down amount is the amount of protrusion of the rotating body shaft 70 from the bottom plate 76. The ground terminal 106 bends and urges the rotating body shaft 70. The contact between the rotating body shaft 70 and the ground terminal 106 is not released by a slight impact.

The operation of setting the coin hopper on the first mounting table 50 will be described. An identification protrusion 108 indicating a predetermined denomination is fixed to the first mounting 50th. Only a coin hopper having an identification hole 87 suitable for the identification protrusion 108 can be set. The insertion position is determined by the guide portion 90 so that the flat surface of the frame portion 101 or the base portion 100 does not come into contact with the first connector 84 or the rotating body shaft 70.

First, the step portion 75 fits into the guide portion 90, and the coin hopper moves to the back inside the frame portion 101 along the guide portion 90. Next, the tip of the positioning protrusion 109 is inserted into the positioning hole 86, and the tip of the first connector 84 is inserted into the second connector 104. By further moving the coin hopper to the back of the frame portion 101, the support leg 71 is inserted into the leg escape portion 102. After that, the flat portion of the bottom plate 76 comes into contact with the flat portion of the base 100, and the bottom surface 98 of the shaft comes into contact with the ground terminal 106 and pushes down the ground terminal 106 by the time the coin hopper is placed. The ground terminal 106 is deformed by the rotating body shaft 70. In this state, the first connector 84 fits into the second connector 104 and is electrically connected. Due to the weight of the coin hopper, the coin hopper can be set on the first mounting table 50 without being lifted by the elasticity of the ground terminal 106.

The bottom surface 98 of the shaft comes into contact with the ground terminal 106 and can be grounded. The amount of bending of the ground terminal 106 is the amount of protrusion of the rotating body shaft 70 from the bottom plate 76. This protrusion amount is smaller than the protrusion amount of the support leg 71. Since the amount of bending is small, the force with which the ground terminal 106 pushes the rotating body shaft 70 is also small, and does not affect the rotation of the rotating body shaft 70. The ground terminal 106 is, for example, a plate-shaped spring. A configuration in which one end is fixed and the other end is a free end is conceivable. Further, a plate-shaped spring that fixes both ends and bends the central portion may be used.

Further, it is preferable that the ground terminal position 105 when the ground terminal 106 is not connected is a position that does not protrude from the ground groove 103. Since the ground terminal 106 does not protrude from the ground groove 103, damage due to contact with other objects can be prevented.

FIG. 11 is a second example of a coin hopper grounding method. One end of the spring 110 is fixed to the ground groove 103, and the ground terminal 106 is fixed to the other end. The ground terminal 106 has a flat portion in contact with the bottom surface of the shaft 98 and is bent around the ground terminal 106. The spring 110 indicating the ground terminal 106 is pushed by the rotating body shaft 70 from the position of the ground terminal position 105 when not connected and contracts. Connect the ground line 107 to the spring 110 or the ground terminal 106. The ground terminal 106 has a structure in which the contact surface with the bottom surface 98 of the shaft is flattened and the ground terminal 106 moves along the axial direction of the rotating body shaft 70. The shaft bottom surface 98 preferably contacts the ground terminal 106. The flat surface of the tip of the ground terminal 106 protrudes from the ground groove 103, but the tip of the bent portion around the ground terminal 106 is arranged inside the ground groove 103.

FIG. 12 is a third example of a coin hopper grounding method. The rotating body shaft 70 does not protrude from the bottom plate 76. In this case, the ground terminal 106 is arranged so as to project from the ground groove 103. At this time, the ground terminal 106 is arranged so as not to come into contact with the bottom plate 76.

FIG. 13 is a diagram illustrating an example in which a coin hopper is set on a mounting table. An example of the arrangement of the ground terminal 106 in the ground groove 103 will be described. The ground groove 103 is a groove provided in the base 100. The bottom surface of the ground groove 103 is a flat surface, on which the ground base 111 is arranged. The ground base 111 is a metal substrate. A part of the earth base 111 is cut and bent to form a spring-like body. The spring-like body is the ground terminal 106. Connect the ground base 111 to ground. The ground terminal 106 is integrally provided with the ground base 111, which is a metal substrate. The bottom surface 98 of the coin hopper comes into contact at the contact position 112. The contact position 112 is preferably provided with a flat portion so as to be in surface contact with the shaft bottom surface 98. Further, by providing one ground base 111, it is possible to ground a plurality of coin hoppers arranged in a row. Although it is possible to individually provide the ground base 111 for the coin hopper, it is preferable to use one ground base 111 for grounding the plurality of coin hoppers in consideration of assembleability.

FIG. 14 is a diagram illustrating another example of the contact portion of the coin hopper with the ground terminal. The tip of the rotating body shaft 70 of the coin hopper does not protrude from the bottom plate 76. Instead, it is provided with a contact portion 115 protruding from the bottom plate 76. The contact portion 115 is preferably arranged on an extension line of the rotating shaft of the rotating body shaft 70. The contactor 113 is arranged under the drive gear 95 arranged on the lower side of the rotating body shaft 70. The contact 113 is an electrode for contacting the rotating body shaft 70, and makes contact in a state of being urged in the direction of the rotating body shaft 70. Since the contact 113 is pressed against the rotating body shaft 70, the contactor 113 is always electrically connected to the rotating body shaft 70. It is preferable to provide the contacts 113 at two or more places. Each contact 113 is connected to the contact portion 115 by a ground connection wire 114. The tip of the contact portion 115 is flat and protrudes from the bottom plate 76 as in the shaft bottom surface 98 (FIG. 9). The coin hopper has a large number of parts, which makes it difficult to manufacture. On the other hand, since no external force is applied to the rotating body shaft 70, stable rotational operation can be performed.
