Description

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

A coin hopper that ejects coins one by one from a coin container storing a plurality of coins is known. The coin hopper can discharge coins one by one and count the number of discharged coins. A coin processing device such as an automatic change dispenser is provided 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 coins to be discharged for each denomination. When change data is input, the coin processing device drives a coin hopper corresponding to the denomination included in the change data and discharges the specified number of coins. The ejected coins are accumulated in the receiving port and handed over to the user.

The coin hopper has a container for storing coins and a rotating disk with openings for inserting coins one by one. For example, Japanese Patent Application Laid-Open No. 2013-250777 describes a coin hopper that discharges coins in a container one by one. If the coins in the container are electrically charged, the coin hopper may have problems when the coins are 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 the conductive path.

A coin processing device equipped with a coin hopper is also known. For example, the coin processing device described in Japanese Patent Application Laid-Open No. 2017-151818 has a process of separating and sending out a plurality of coins inserted from an insertion port one by one, and then determining the denomination of the coins conveyed one by one. A step of identifying and then storing the identified coins by denomination.

In the step of separating and sending out a plurality of coins inserted from the slot one by one, a tilted base and a disk rotating thereon are used. A storage container for storing coins is arranged below the disk. For example, the storage container is arranged so as to cover approximately half of the lower portion of the disc. A plurality of inserted coins are temporarily stored in the storage container. Spin the disc and pick up the coins in the storage container one by one. The disk is provided with a recess for receiving one coin. As the concave portion of the rotating disc passes through the storage container, only one coin accumulated in the storage container enters the concave portion and is transported. Above the disk, there is a mechanism for transferring coins to the next process. The coin is conveyed above the disk and handed over to the next process. The next step is to identify the denomination of the coin passed. The denomination of the coin is identified by multiple sensors that detect characteristics such as the size and material of the coin.

In the coin processing device, the coins are passed to the next process after the coins are identified. In the next step the coins are transported by a belt. A slide is 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 denomination-identified coins are dropped onto the corresponding denomination slide during transport. The coins dropped on the slide slide down to the storage container of the coin hopper by denomination and are stored there.

The coin hopper can discharge coins one by one. For example, an automatic change dispenser calculates the denomination and number of coins to be discharged according to the amount of change, controls the coin hopper corresponding to each denomination, and discharges coins according to the amount of change.

A storage container for storing coins of the coin hopper stores a plurality of coins. Coins stored in the storage container are agitated as the disk rotates. Contact between coins, coin and container, coin and disc, coin and base, etc., creates static electricity. When ejecting a charged coin, electrical discharge occurs between the coin and electronic components such as sensors and connectors. As a result, the charged coins cause troubles such as failure of electronic parts and erroneous detection of sensors. In addition, a coin processing device equipped with a coin hopper causes problems such as shortage of discharged coins and overpayment.

Further, when an electrode for grounding is arranged in the storage container, there is a problem that the coins do not come into contact with the electrode when the number of coins in the storage container is small.

The present invention provides a coin hopper and a coin processor capable of suitably removing static electricity in the coin container of the coin hopper, preventing malfunctions such as erroneous sensor detection and failure, and suitably discharging coins.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Each drawing is merely a schematic representation to the extent that the present invention can be fully understood. Accordingly, the present invention is not limited to the illustrated examples only. Moreover, in each figure, the same code|symbol is attached|subjected about a common component and a similar component, and those overlapping description is abbreviate|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 the coins in a coin hopper by denomination, and discharges the desired denomination and 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 exterior case. A coin processing device 1 is provided with an insertion slot 2 for inserting coins and a tray 3 for receiving coins to be paid out.

An opening of an insertion port 2 for inserting coins is arranged on the front side of the upper surface of the exterior case. A tray 3 for receiving coins to be paid out is arranged on the front surface of the exterior case. A payout port 4 penetrating between the inside and the outside of the coin processing device 1 is provided at a position corresponding to the tray 3 . A tray 3 receives coins paid out through a payout port 4. - 特許庁A display device 5 is arranged next to the inlet 2 . The display device 5 displays the state of the coin processing device 1, the amount of deposit, the amount of withdrawal, guidance, and the like. A device for separating, identifying, storing, and dispensing inserted coins is housed in the exterior 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 change machine. A coin is inserted into the slot 2. A control unit (not shown) acquires the denomination and number of inserted coins, and grasps the amount of money inserted. The presence or absence of a payout 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 discharge the 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 for explaining the configuration of the coin processing device. Commonly used coins consist of multiple denominations. Elements such as size, material, and design of coins differ for each denomination.

The coin processing device 1 separates the inserted coins one by one, identifies the denomination of each separated coin, and stores the identified coins by denomination. In addition, 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 for sorting and sending out inserted coins one by one, an identification unit 8 for discriminating coin denominations, and a sorting unit 9 for sorting and storing coins by denomination.

Coins of a plurality of denominations are mixed and thrown into the slot 2 of the coin processing device 1.例文帳に追加A coin 10 inserted into the slot 2 passes through a coin passage 11 and is stored in a storage container 12.例文帳に追加The slot 2, the coin passage 11, and the storage container 12 are indicated by dashed lines in FIG.

A disk 15 and a wheel 21 for carrying the coin 10 are arranged on the upper surface of the holding base 13 . A storage container 12 is arranged below the disk 15 in the vertical direction. The reservoir 12 has a bottom shaped around the circumference of the disk 15 . The reservoir 12 covers the lower half to one-third of the disc 15 . A coin 10 is stored in a portion surrounded by a disk 15 and a storage container 12. - 特許庁

The disk 15 is provided with three disk recesses 16 for holding the coins 10 . The coin 10 enters the disc recess 16 and is conveyed. Also, the area on the outer peripheral side of the disc 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 with an inclination with respect to the horizontal direction. In the storage container 12, the coin 10 leans against the disk 15 side. The coins 10 in the storage container 12 move relative to the disk 15 as the disk 15 rotates. A coin 10 enters a disc recess 16 passing through the reservoir 12 .

The side surface of the coin 10 that has entered the disc recess 16 contacts the inner wall of the disc recess 16 . Since the holding base 13 and the disk 15 are arranged so as to take an oblique posture with respect to the horizontal direction, the coin 10 can be held in the disk concave portion 16 of the disk 15 . The inclination angle of the holding base 13 is set within the range of 30 degrees to 80 degrees. 40 degrees to 50 degrees is more preferable. If the inclination angle is small, unnecessary coins 10 cannot slide down from the disc recess 16, and if the inclination angle is large, it becomes difficult for coins to enter the disc recess 16. - 特許庁The height of the inner wall of the disc recess 16 is lower than the thickness of the coin 10 so that only one coin 10 can be inserted. Considering 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 therein. Also, only one coin 10 of the maximum size can be inserted into the disk concave portion 16.例文帳に追加

The coin 10 is held in such a posture that the front surface or the back surface of the coin 10 faces the flat bottom surface of the disc recess 16 . In addition, since the inner wall of the disk recess 16 is interrupted in the area on the outer peripheral side of the disk 15, the coin 10 is transferred to the next process through this interrupted area. A guide wall that guides the coin 10 in the direction of rotation of the disk is arranged outside 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 a disk rotation axis 14 in a disk rotation direction 17 indicated by an arrow. The disc recess 16 picks up the coins 10 stored in the storage container 12 one by one. Since the disk 15 is arranged obliquely with respect to the horizontal direction, the coins 10 in the storage container 12 lean against the disk 15 . A coin 10 leaning against the disk 15 easily enters the disk recess 16.例文帳に追加

A coin 10 is delivered at a position above the separation section 6 and below the identification section 8 . Although FIG. 2 shows an example in which the identification section 8 and the separation section 6 are arranged vertically, the identification section 8 and the separation section 6 can be arranged horizontally. The disk 15 can convey the coins 10 one by one to the delivery section 7 and deliver the coins 10 to the identification section 8 in the next process.

A wheel 21 rotates about a wheel rotation axis 20 in a wheel rotation direction 22 indicated by an arrow. The wheel 21 rotates in conjunction with the rotation of the disc 15 . The coin 10 sent out from the separating section 6 has its side surface in contact with the wheel 21 and is pushed by the wheel 21 to slide on the holding base 13 . The holding base 13 is a flat plane. 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 characteristics of the coin 10 moving on the holding base 13 are 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 one by one by the wheel 21 and conveyed, the identification sensor 19 can preferably detect the characteristics of the coins 10 one by one. The coin 10 is pushed by the wheel 21 and moved along the guide section 18 with its front or back surface in contact with the holding base 13 and its side surface in contact with the guide section 18 . The coin 10 whose denomination has been identified by the identification unit 8 is transferred to the distribution unit 9 in the next process.

Rails 25 for guiding the coins 10 are arranged in the sorting section 9 . A coin 10 is passed from the identifying section 8 to the rail 25 of the sorting section 9 . A coin 10 is conveyed along this rail 25 . A conveyor belt 24 is arranged along the rail 25 . Conveying pin rollers 23 are arranged at regular intervals on the conveying belt 24 . One coin 10 enters between the conveying pin rollers 23. - 特許庁The transport pin roller 23 pushes the coins 10 one by one and transports the coins 10 along the rail 25 . The conveying pin roller 23 can also be said to be a pushing body that pushes and conveys the coin 10 . The transport belt 24 is an endless belt and rotates in conjunction with the discs 15 and wheels 21 in a transport belt rotation direction 26 indicated by an arrow.

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 along the rail 25 . These sliders are connected to coin hoppers or bins of predetermined denominations. The coins 10 identified by the identification unit 8 are dropped onto the corresponding denomination slider and stored in the corresponding denomination coin hopper or container.

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

The eighth slider 41 guides the coin 10 to the ejection belt 42 . A coin 10 whose denomination cannot be identified or a coin 10 that cannot be used is guided onto a discharge belt 42 and discharged to a tray 3.例文帳に追加

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. When the coins 10 cannot be stored in the coin hopper, the coins 10 that cannot be stored are stored in the overflow container 40.例文帳に追加When coins 10 are dispensed from the full coin hopper, the coin hopper can store the coins 10 again. The number of times of maintenance of the coin processing device 1 can be reduced by the configuration in which the coins 10 that cannot be stored in the coin hopper are stored in the overflow container 40.例文帳に追加The coin processing device 1 is efficiently operated. As long as the overflow container 40 can store the coins 10, the overflow container 40 may be a container without a function to discharge the coins, or may be a coin hopper.

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 also be said to be a coin receiving portion that receives and collects the coins 10 discharged from the coin hoppers. Coins 10 put into the slot 2 are reused as coins 10 for payout. In addition, the coin hopper is electrically connected to the coin processing device 1 in order to release static electricity charged on the coins 10 stored in the coin hopper. The coin processing device 1 and the coin hopper are electrically connected by placing the coin hopper on a mounting table provided in the coin processing device 1, which will be described later.

The disc 15 rotates around the disc rotating shaft 14 . Wheel 21 rotates around wheel rotation axis 20 . The disk rotating shaft 14 and the wheel rotating shaft 20 are rotated by a motor (not shown). A gear train (not shown) connects the motor and the disk rotating shaft 14 . Further, the motor and the wheel rotation shaft 20 are connected by a train wheel (not shown). The gear train reduces the speed of rotation of the motor at a predetermined ratio. The motor and train constitute the drive that rotates the disc 15 and wheel 21 .

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

The disk 15 is provided with a plurality of disk recesses 16 equiangularly around the disk rotating shaft 14 . For example, three locations are provided at intervals of 120 degrees. A lever 43 is arranged in each disc recess 16 . When the coin 10 is delivered to the delivery section 7, this lever 43 operates. The lever 43 pushes the coin 10 toward the outer circumference of the disk 15, that is, toward the identification portion 8. As shown in FIG. The coin 10 is transferred from the separation section 6 to the identification section 8 .

A coin 10 is pushed out of the disc 15 of the separating section 6 and picked up by the wheel 21 of the identifying section 8 .

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

In the discriminating unit 8, the coins 10 moving along the guide unit 18 are detected one by one by the discriminating sensor 19 to discriminate the denomination. In the guide portion 18, guide walls are 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 identifying section 8 to the sorting section 9 . A coin 10 pushed by the wheel 21 is passed on the rail 25 . The wheel 21 and the conveyor belt 24 rotate together. Conveying pin rollers 23 are arranged on the conveying belt 24 so that one coin 10 is inserted between the adjacent conveying pin rollers 23 .

A coin 10 moving along a rail 25 is dropped onto a slider corresponding to the denomination. Coins 10 of the same denomination are stored in the coin hopper.

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

In the separating section 6 , the inserted coins 10 are 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 transported to the delivery section 7 , the lever 43 operates to push the coin 10 toward the identification section 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 that covers the identification section 8 is open. In normal use, the sensor cover is closed.

The coin 10 is pushed by the wheel 21 in the identification section 8 . The coins 10 move on the holding base 13 one by one. The guide portion 18 is arranged below the identification portion 8 . The guide portion 18 is obliquely arranged so that the traveling direction of the coin 10 is higher in the vertical direction. The guide part 18 is part of a guide wall arranged outside the outer circumference of the wheel 21 . The guide portion 18 is a guide wall arranged linearly in order to detect the coin 10 under certain conditions. A 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 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 rear surface is in contact with the holding base 13 . A downward force is applied to the coin 10 by gravity. After passing the lowest point, the wheel 21 conveys the coin 10 upward against gravity. The coin 10 is conveyed while being in contact with the guide portion 18 . The outer circumference of the coin 10 slides or rolls while being 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 has been identified by the identification sensor 19 is transferred from the identification section 8 to the sorting section 9 . One coin 10 enters between the conveying pin rollers 23. - 特許庁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 discriminating section 8 are separated one by one by the conveying pin roller 23 in the distributing section 9 and conveyed.

The coins 10 identified by the identifying section 8 are dropped onto any of the sliders of the sorting section 9 during transportation.

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

FIG. 4 is a diagram for explaining an arrangement example of coin hoppers mounted on the coin processing apparatus. A first mounting base 50 and a second mounting base 51 for mounting the coin hopper are arranged with the discharge belt 42 interposed therebetween. The coin hoppers are arranged in rows on each side of the discharge belt 42 .

A first coin hopper 28 , a second coin hopper 30 , and a third coin hopper 32 are mounted 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 mounted in a row on the second mounting table 51 .

The first discharge port 53 is an opening through which the coins 10 of the first coin hopper 28 are discharged. The second discharge port 54 is an opening through which the coins 10 of the second coin hopper 30 are discharged. The third discharge port 55 is an opening through which the coins 10 of the third coin hopper 32 are discharged. 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 looped around a pulley 52 and a drive pulley (not shown). By driving the drive pulley with a motor (not shown), the ejection belt 42 is rotated, and the coins 10 ejected on the ejection belt 42 are guided to the tray 3 through the outlet 4 .

The coin hopper is optimized according to denominations. 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 coin hoppers mounted on the first mounting table 50 and the second mounting table 51 are set in predetermined positions according to denominations. Identification projections are arranged on the first mounting table 50 and the second mounting table 51 to prevent the coin hopper from being set in the wrong position. The shape of the identification protrusion is a shape predetermined according to the denomination. The coin hopper is provided with recesses corresponding to identification projections corresponding to denominations. The coin hopper cannot be set on the first mounting table 50 unless the identification projection and the recess match. The same applies to the second mounting table 51 .

A coin hopper of a denomination corresponding to a predetermined position can be easily arranged by the first mounting table 50 and the second mounting table 51 .

Next, the coin hopper will be explained. FIG. 5 is a perspective view of the coin hopper. The coin hopper uses settings optimized for each denomination, but the basic configuration is the same for all denominations.

A coin hopper is a device that separates and discharges a plurality of coins one by one. The coin hopper is roughly divided into a main body 60 and a coin storage container 61. - 特許庁The coin storage container 61 is detachable from the main body 60 . The coin storage container 61 is open at a portion facing a rotating body, which will be described later. The connecting portion 64 is the outer peripheral portion of the opening. A plurality of coins 10 of a predetermined denomination can be stored in the coin storage container 61 . The coins 10 in the coin container 61 are deposited on the rotating body. The main body 60 is covered with a case and has a drive mechanism inside. The main body 60 is provided with a mechanism that separates and discharges the plurality of coins 10 one by one using a rotating body, which will be described later.

A stirring rod 65 is a metal rod fixed to the coin storage container 61 . The stirring rod 65 is fixed to the coin container 61 and has a spring at its base. The tip side of the stirring rod 65 moves in various directions due to the elasticity of the spring on the root side. The coins 10 in the coin storage container 61 are moved by rotating a rotator, which will be described later. Since the coins 10 in the coin storage container 61 can be stirred by the stirring rod 65, it is possible to prevent the coins 10 from overlapping and forming a bridge. A motor 69 drives the 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 side surfaces of the coin storage container 61 .

A payout port 62 for ejecting coins 10 is provided on one side of the main body 60 . The side of the main body 60 where the outlet 62 is provided is called the front side, and the opposite side is called the back side. Coins 10 are discharged one by one from a payout port 62.例文帳に追加The ejected coin 10 is detected by the payout sensor 63 . By detecting the coin 10 with the payout sensor 63, it can be known that the coin 10 has been paid out.

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

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

The coin storage container 61 of the coin hopper has a container inclined portion 74, which guides the coins 10 to a rotator which will be described later. Coins 10 are deposited on the lower side of coin container 61 .

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

A second support projection 73 is provided on the side surface of the coin storage container 61 . The second support projection 73 fits into the hole provided in the second support portion 67 . Also, a first support projection is provided on the opposite side. The first support projection fits into a hole provided in the first support portion 66 (FIG. 5). Both side surfaces of the coin storage container 61 are supported by the main body 60 .

A stepped 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 body 60 by the stepped portion 75 . The stepped 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 projection 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 .

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

A support leg 71 is arranged on the bottom plate 76 . The support legs 71 protrude from the bottom plate 76 . As viewed from the side, the rotor shaft 70 is arranged between the support leg 71 and the front end portion 72 of the bottom plate 76 . A guide groove 68 is arranged between the support leg 71 and the front end portion 72 in a side view. 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 rotor shaft 70 is separated from the flat surface. When the coin hopper is placed, objects can be prevented from contacting the rotating body shaft 70.例文帳に追加Also, the distance from the front end 72 to the rotor shaft 70 is longer than the distance from the rotor shaft 70 to the support leg 71 . That is, the rotating body shaft 70 is arranged to be closer to the support leg 71 side than the front end portion 72 is. It is preferable to arrange the support legs 71 near the rotor shaft 70 so that the rotor shaft 70 does not hit objects. Further, three or more support legs 71 may be provided so as to surround the rotor shaft 70, or a frame may be provided instead of the support legs 71.

As viewed from the side, the rotor shaft 70 is arranged between two stepped portions 75 of the guide groove 68 . The guide groove 68 is arranged along the vertical direction with respect to the bottom plate 76 . When setting the coin hopper on the mounting table, the coin hopper moves along the guide groove 68 from top to bottom. That is, the coin hopper moves from top to bottom along the direction in which the stepped portion 75 extends. The tip of the rotor shaft 70 similarly moves from top to bottom.

FIG. 7 is a perspective view of the main part of the coin hopper. 6 is a perspective view of the main body 60 of the coin hopper; FIG.

A hopper base 81 is arranged on the upper surface side of the main body 60, and a rotating body 80 is arranged thereon. The rotating body 80 is fixed to the rotating body shaft 70 (FIG. 6) by screws 77 . The screw 77 is a conductive metal screw. Rotating body recesses 82 into which coins 10 are inserted are provided at four locations on the rotating body 80 .

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

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

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

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

The tip side of the rotating shaft of the motor 69 is connected to a wheel train (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 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 rotor 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 dispensing port 62 side. An identification hole 87 is arranged inside the positioning hole 86 . The positioning hole 86 is provided with semicircular projections in eight radial directions from the center. Any one of the 8-direction projections is deeply recessed. The position of this depression indicates the corresponding denomination. A projection 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 end of the bottom plate 76 opposite to the outlet 62 side. The first connector 84 is a connector for connecting various signal lines and a power source for controlling 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 will not come off from the cable groove 89 due to vibration. Making the opening of the cable groove 89 narrower than the bottom makes it difficult for the cable 88 to come off the cable groove 89 . Cable 88 is a cable in which a plurality of lines are combined into one.

The payout sensor 63 and the first connector 84 are arranged at respective longitudinal ends of the coin hopper. Inside the main body 60, a driving mechanism for a rotating body 80 (FIG. 7) is arranged. If the cable 88 comes into contact with the drive mechanism, disconnection or drive failure will occur. Therefore, it is necessary to either fix the cable 88 or provide means for separating the cable 88 and the drive mechanism. However, when a means for preventing contact between the cable 88 and the drive mechanism is provided, there are restrictions on the arrangement position of the cable 88 and the communication position between the inside and outside of 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 where the cable 88 and the drive mechanism do not come into contact with each other. A first connector 84 is arranged at one end of the main body 60, and a payout sensor 63 is arranged at the other end. If both can be arranged on either side, the arrangement of the cable 88 is facilitated, which is preferable. If this is not possible, it is preferable to place the cable 88 in a groove on the exterior of the body 60 .

Two support legs 71 are provided on the bottom plate 76 . A rotating body shaft 70 is arranged at a position surrounded by both ends of the front end portion 72 and two supporting legs. The rotor shaft 70 protruding from the bottom plate 76 is protected by the support legs 71 . The rotor shaft 70 is arranged substantially in the center of the coin hopper in the width 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 a coin hopper, it is easy to place.

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

The coin storage container 61 can store a plurality of coins 10 . Coins 10 are deposited on rotating body 80 . The rotating body 80 is rotated to convey the coin 10 that has entered the rotating body concave portion 82 . By rotating the rotating body 80 , the pressing wall 78 on the inner circumference of the rotating body concave portion 82 comes into contact with the peripheral surface of the coin 10 . The coin 10 moves as the rotor 80 rotates. A coin 10 slides on the hopper base 81 .

Since the charged coin 10 may adversely affect electronic parts, it is necessary to release the static electricity. When the hopper base 81 and the coin storage container 61 are made of resin, the static electricity of the coins 10 cannot escape from the hopper base 81 and the coin storage container 61 to the ground.

The rotating body 80 is fixed to the rotating body shaft 70 by screws 77 . The rotor shaft 70 is a metal shaft and is conductive. For example, a shaft made of stainless steel. Also, the screw 77 is also made of metal and is conductive. The tip of the rotor shaft 70 protrudes from the bottom plate 76 of the main body 60 . The tip of the rotor shaft 70 has a flat shaft bottom surface 98 . The static electricity of the charged coin 10 can be transmitted to the shaft bottom surface 98 via the rotating body shaft 70 . The static electricity of the coin 10 can be released by bringing a terminal connected to the ground into contact with the bottom surface 98 of the shaft. That is, the coin 10 is electrically connected 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 rotor shaft 70 . For example, parallel to the flat surface of the hopper base 81 . If the shaft bottom surface 98 were formed obliquely in the axial direction of the rotating body shaft 70 , the tip would be sharp and the terminal in contact with the shaft bottom surface 98 would be damaged.

If 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 is conducted to the bottom surface 98 of the shaft.

If 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 is conducted to the bottom surface 98 of the shaft.

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

Further, the bottom plate 76 is provided with a through hole for exposing the rotor shaft 70 to the outside. For example, the rotor shaft 70 can be passed through the through hole and protrude from the bottom plate 76 . The rotor shaft 70 is rotatably supported by a second sliding portion 93 including a bearing portion 91 arranged inside the bottom plate 76 . The rotor shaft 70 has a reduced diameter at the bearing portion 91 . The rotor shaft 70 does not come off 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 rotor shaft 70 passes 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 rotor shaft 70 is exposed to the outside through a through hole provided in the bottom plate 76 . For example, static electricity can be released to the outside by contacting the tip of the rotor shaft 70 exposed from the through-hole with the ground. The through hole of the bottom plate 76 is also called a first through hole, and the through hole of the bearing portion 91 is also called a second through hole. The tip of the rotor 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 outside the main body 60, and the shaft bottom surface 98 is brought into contact with the ground terminal. The static electricity of the charged coin 10 can be released to the outside of the main body 60 from the bottom surface 98 of the shaft. However, since the rotator shaft 70 and the external grounding terminal are brought into contact with each other, external force is applied to the rotator shaft 70 . Since an external force is applied to the rotor shaft 70, the rotation of the rotor shaft 70 may be adversely affected. For example, rotation unevenness, shaft vibration, 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 least at two points. Between the first sliding portion 92 and the second sliding portion 93 , a driving gear 95 at the final stage of the gear train is fixed to the rotating body shaft 70 . By arranging the final-stage drive gear 95 between the support portions, the drive force is transmitted while suppressing the influence of external force.

Since the rotator shaft 70 is brought into contact with an external grounding terminal, external force is applied to the rotator 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. Rotating body 80 can be rotated. It is possible to prevent the rotating body shaft 70 and the rotating body 80 from floating due to the force from the ground terminal.

The rotating body shaft 70 is arranged at the center of the rotating body 80 when viewed from above. Since a plurality of coins 10 are accumulated on the rotating body 80, the rotating body 80 is subjected to a considerable load. Since the rotating body 80 is rotated in this state, it is preferable that the position of the rotating body shaft 70 in a top view is at the center of gravity or at a position close to the center of gravity. If the rotating body shaft 70 is away from the center of gravity, the coin hopper is likely to sway, which may cause vibration.

A drive gear 95 is fixed to the rotor shaft 70 . Further, the strength of the bottom plate 76 is increased by ribs 96 that protrude inside the main body 60 of the bottom plate 76 . Rib 96 and drive gear 95 do not touch.

A cable groove 89 for receiving the cable 88 forms a protruding cable groove inner wall 97 inside the body 60 . It is also a rib that improves the strength of the main body 60 . In addition, since the cable 88 can be separated from the outside by the inner wall 97 of the cable groove, maintenance such as replacement of the cable 88 can be easily performed. Moreover, since it is not necessary to isolate the cable 88 from contact with other parts during maintenance, maintenance work can be reduced. Also, by minimizing the number of wiring members in the main body 60, assembly becomes easier and maintenance becomes easier.

FIG. 10 is a first example of a method for grounding the coin hopper. 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 forming a bottom surface and a frame portion 101 forming a periphery. The coin hopper is set on the base 100 with the coin storage container 61 facing up and the main body 60 facing down.

A ground groove 103 is provided in a portion of the base portion 100 corresponding to the rotating body shaft 70 of the coin hopper. The base 100 is provided with leg recesses 102 at portions corresponding to the supporting legs 71 of the coin hopper. The base 100 is provided with depressions in portions corresponding to the rotating body shaft 70 and the support legs 71 of the coin hopper. A second connector 104 is provided on the base 100 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 portions 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 stepped portion 75 of the coin hopper.

The base 100 is provided with projections and depressions in portions corresponding to the unevenness of the coin hopper. , is constructed so as not to rattle. When the coin hopper is placed on the first placement table 50 , the flat portion of the bottom plate 76 of the coin hopper contacts 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 become an obstacle when coins are ejected.

Ground terminal 106 is connected to the ground via 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 positioned at a ground terminal position 105 when the connection is not made, indicated by a dotted line, when the rotor shaft 70 is not in contact. When the coin hopper is set on the first mounting table 50, the shaft bottom surface 98 comes into contact with the ground terminal 106 and pushes it down. The amount of depression is the amount of protrusion of the rotor shaft 70 from the bottom plate 76 . Ground terminal 106 flexes and biases rotor shaft 70 . A slight impact does not release the contact between the rotor shaft 70 and the ground terminal 106 .

The operation of setting the coin hopper on the first mounting table 50 will be described. An identification projection 108 indicating a predetermined denomination is fixed to the first mounting plate 50 . Only a coin hopper having an identification hole 87 that fits this identification projection 108 can be set. The insertion position is determined by the guide portion 90 so that the flat surfaces of the frame portion 101 and the base portion 100 do not come into contact with the first connector 84 and the rotor shaft 70 .

First, the stepped portion 75 is fitted into the guide portion 90 , and the coin hopper moves deep inside the frame portion 101 along the guide portion 90 . Next, the tip of the positioning projection 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 relief portion 102 . Thereafter, the flat portion of the bottom plate 76 abuts the flat portion of the base 100, and the bottom surface 98 of the shaft contacts the ground terminal 106 and pushes down the ground terminal 106 by the time the coin hopper is completely placed. Ground terminal 106 is deformed by rotor 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 contacts the ground terminal 106 and can be grounded. The amount of deflection of the ground terminal 106 is the amount of protrusion of the rotor shaft 70 from the bottom plate 76 . This amount of protrusion is smaller than the amount of protrusion of the support leg 71 . Since the amount of bending is small, the ground terminal 106 exerts a small force to push the rotor shaft 70 and does not affect the rotation of the rotor shaft 70 . The ground terminal 106 is, for example, a plate-like spring. A configuration in which one end is fixed and the other end is free is conceivable. Alternatively, it may be a plate-shaped spring with both ends fixed and the central portion flexed.

Moreover, 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 the method for grounding the coin hopper. 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 98 of the shaft and is bent around. A spring 110 that instructs the ground terminal 106 is pushed by the rotating body shaft 70 and contracts from the position of the ground terminal position 105 at the time of disconnection. Ground line 107 is connected to spring 110 or ground terminal 106 . The ground terminal 106 has a flat contact surface with the shaft bottom surface 98 and is configured to move along the axial direction of the rotor shaft 70 . Shaft bottom surface 98 preferably contacts 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 shows a third example of the method for grounding the coin hopper. The rotor shaft 70 does not protrude from the bottom plate 76 . In this case, the ground terminal 106 is arranged to protrude from the ground groove 103 . At this time, the ground terminal 106 is arranged so as not to contact the bottom plate 76 .

FIG. 13 is a diagram illustrating an example of setting the coin hopper on the mounting table. An example of arrangement of the ground terminal 106 in the ground groove 103 will be described. A ground groove 103 is a groove provided in the base portion 100 . The bottom surface of the ground groove 103 is a flat surface, and the ground base 111 is arranged thereon. The ground base 111 is a metal substrate. A portion of the ground base 111 is cut and bent to form a spring-like body. The spring-like body is used as the ground terminal 106 . Connect ground base 111 to ground. A ground terminal 106 is provided integrally with a ground base 111 that is a metal substrate. The bottom surface 98 of the coin hopper makes contact at contact location 112 . Contact location 112 preferably includes a flat to provide surface contact with shaft bottom surface 98 . Also, by providing one earth base 111, it becomes possible to earth a plurality of coin hoppers arranged in a line. Although the ground base 111 can be provided individually for each coin hopper, it is preferable to ground a plurality of coin hoppers with one ground base 111 in consideration of ease of assembly.

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 shaft 70 of the coin hopper does not protrude from the bottom plate 76. - 特許庁Instead, a contact portion 115 protruding from the bottom plate 76 is provided. The contact portion 115 is preferably arranged on an extension of the rotation axis of the rotor shaft 70 . A contact 113 is arranged below the drive gear 95 arranged below the rotor shaft 70 . The contactor 113 is an electrode with which the rotor shaft 70 is brought into contact, and contacts with the rotor shaft 70 biased in the direction of the rotor shaft 70 . Since the contactor 113 is pressed against the rotor shaft 70 , the contactor 113 is always electrically connected to the rotor shaft 70 . It is preferable to provide two or more contacts 113 . Each contact 113 is connected to a 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 in the same manner as the shaft bottom surface 98 (FIG. 9). Since the coin hopper has a large number of parts, it is difficult to manufacture. On the other hand, since no external force is applied to the rotor shaft 70, stable rotation can be achieved.
