Japanese Patent Application Laid-Open No. 2001-134800 (Figures 1 to 3, paragraphs 0011 and 0012) JP 2010-131122 (Figures 1 to 11, paragraph 0007) JP 2014-174720 (Figures 1 to 17, paragraph 0007) JP 2018-012864 (Figures 1 to 20, paragraphs 0014 and 0068)

In the first prior art, a coin is sandwiched between a guide member and a payout roller attached to an arm biased by a spring and ejected, the arm is prevented from moving by a stopper, and the payout roller and the guide member move. Predetermined intervals are maintained between The stopper is made of an elastic material such as rubber, and is designed to reduce impact when it comes into contact with the stopper.

There is no mention of the material of the abutment body.

In the disk feeding device, a rocking lever to which an ejection roller for ejecting a disk such as a coin is attached is brought into contact with an elastic body as a stopper to reduce impact noise and improve durability. Urethane rubber, which is superior in mechanical properties to rubber, in other words, is durable, is usually used as the elastic body in consideration of durability, availability, and cost. Urethane rubber is classified into ether type and ester type.
Ether-based urethane rubber does not undergo hydrolysis, but its mechanical strength is inferior to that of ester-based urethane rubber, in other words, its durability is inferior. Not suitable for stoppers that receive the impact of ejection rollers.
Ester-based urethane rubbers are superior in mechanical strength and are more durable than ether-based urethane rubbers. However, since the ester-based urethane rubber is hydrolyzed, it is not suitable for long-term use in a high-humidity atmosphere. The reason is explained below.
The disc delivery device is usually installed in a vending machine or a money changer and used as a coin dispensing device, so it is used in a harsh natural environment. For example, during the summer in Japan, the vending machine is used under high humidity conditions, and water entering the housing of a vending machine or the like is difficult to escape from the housing, which may accelerate hydrolysis.
As described above, since the ester-based urethane rubber is hydrolyzed, when used under high-humidity conditions, the hydrolysis may cause stickiness and stickiness. If the stickiness of the stopper occurs on the stopper of the disc delivery device, there is a concern that the disc may not be delivered smoothly.

This concern will be explained with reference to FIG.
In FIG. 16, C is a disk, 12 is a flat base, 14 separates the disk C one by one, and pushing pieces 16 (inner pushing piece 16i, outer pushing piece 16e) protruding from the bottom surface. 18 is a C-shaped peripheral surface guide body that guides the peripheral surface of the disc body C pushed by the inner pushing piece 16i and the outer pushing piece 16e; 22 is a fixed guide body substantially fixed at one end of the outlet opening 20; and 24 is a discharge roller. The ejection roller 24 extends from the tip of a rocking lever 28 rotatably provided around a support shaft 26 projecting from the back side of the base 12 to an arc-shaped elongated hole (not shown) formed in the base 12. It is rotatably supported by the tip of a shaft 30 protruding to the surface side of the base 12 via. The rocking lever 28 is biased toward the fixed guide body 22 by a spring 32 as an elastic body. A stopper 38 made of urethane rubber is fixed to the rocking lever 28 side of the stopper piece 34 protruding downward from the back surface of the base 12 . The movement of the contact portion 40 of the rocking lever 28 is restricted by the stopper 38 . That is, the ejection roller 24 is prevented from moving by the stopper 38, and cannot approach the fixed guide body 22 by a predetermined distance smaller than the diameter of the disk C.
Therefore, when the disc body C is not sent out, the contact portion 40 of the rocking lever 28 is pressed against the stopper 38 with a predetermined force by the elastic force of the spring 32 .

When the disc body C is sent out, the disc body C falls between the pushing pieces 16 through a through hole (not shown) due to the rotation of the rotating disc 14 and is separated one by one. reaches the exit opening 20 while being guided by
The disc body C is initially pushed in the radial direction of the rotary disc 14 by the pushing piece 16 while being guided by the stationary guide body 22 on one side of the rear arcuate surface on the forward side in the traveling direction and by the ejection roller 24 on the other side. be moved. As a result, the ejection roller 24 is moved away from the fixed guide body 22 . Due to the movement of the ejection roller 24, the rocking lever 28 is rotated clockwise in FIG. When the fixed guide body 22 and the ejection roller 24 are in contact with the arcuate surface on the forward side of the disk C in the traveling direction, the fixed guide acts on the disk C by the elastic force applied by the spring 32 to the ejection roller 24. The resultant force from the body 22 and the ejecting roller 24 is in the direction of returning the disc body C toward the center of the rotating disc 14 . However, immediately after the center of the disc body C passes through the straight line connecting the points of contact between the disc body C and the fixed guide body 22 and the points of contact between the disc body C and the ejection roller 24, the fixed guide body 22 and the ejection roller 24 Since the disc body C is in contact with the posterior side arcuate surface of the disc body C, the resultant force acting on the disc body C from the fixed guide body 22 and the ejection roller 24 acts in the direction away from the rotating disc 14. The force pulls the rocking lever 28 toward the fixed guide body 22, and the ejection roller 24 pushes the peripheral surface of the rear side of the disc body C to force it out in a certain direction. The ejected disk C is detected by the metal sensor 42 .
When the stopper 38 is not sticky, the rocking lever 28 can also rotate with the movement of the ejection roller 24 . Therefore, the resilient force of the spring 32 causes the disc body C to approach the fixed guide body 22 at a predetermined speed, and the disc body C is delivered at a predetermined speed at a predetermined timing each time.

However, if the stopper 38 becomes sticky due to hydrolysis, the contact portion 40 cannot immediately separate due to the adhesive force of the stopper 38 . In other words, when the front arcuate surface of the disc body C in the traveling direction comes into contact with the ejection roller 24, the rocking lever 28 (contact portion 40) immediately separates from the stopper 38 due to the stickiness of the stopper 38. The contact portion 40 is adhered to the stopper 38 until the elastic force of the spring 32 reaches a predetermined value or more. Then, when the elastic force of the spring 32 reaches or exceeds a predetermined value, the contact portion 40 (swing lever 28) is separated from the stopper 38 momentarily. As a result, the inertial force of the swing lever 28 and the ejection roller 24 increases, and for example, the swing lever 28 overruns from the normal rotation position and then approaches the fixed guide body 22. be moved. Since the rocking lever 28 is rotated more than usual, the spring 32 is stretched more than usual. As a result, the elastic force of the spring 32 is increased, and the ejection roller 24 is moved toward the fixed guide body 22 at a higher speed than usual. As a result, the ejecting speed of the disk C is increased, and there is a possibility that the metal sensor 42 cannot secure a sufficient detection time width, resulting in erroneous detection. In addition, when the ejection roller 24 is moved at a higher speed than usual, the ejection direction of the disk body C becomes different from the normal direction, and there is a possibility that ejection failure may occur.

The operating environment and operating conditions of disk delivery devices in vending machines and the like are extremely diverse, depending on the product to be offered, the place of installation, the amount of money set, and the like. For example, when the stopper 38 is operated frequently, even if hydrolysis occurs in the stopper 38, the contact portion 40 and the stopper 38 are separated before the time elapses until the degree of adhesion between the contact portion 40 and the stopper 38 increases. However, it is rare that the concerns mentioned above actually occur. On the other hand, depending on the location where the vending machine or the like is installed, if the frequency of operation of the disc delivery device is low, for example, it may not operate for more than one day.
As a result, the contact portion 40 is pressed against the stopper 38 for a long period of time, and when the stopper 38 is hydrolyzed, the stickiness of the stopper 38 increases the degree of adhesion, which may cause the above-described erroneous detection or ejection failure.
Even if it is only for a short period of time, if the hydrolysis is progressing, the above defects may occur.

An overview of the disc delivery device 100 will be described with reference to FIG.
The disk body delivery device 100 has a function of sorting and dispensing the randomly stacked disk bodies C one by one. In the first embodiment, the disk body delivery device 100 includes a coin holding container 102, a base 104, a base 106, a peripheral surface guide body 108 (see FIG. 2), a rotating disk 110, a regulation body 112 (see FIG. 2), a ejector The device 113 (fixed guide 114, ejection roller 116, etc.) is the main component.
However, the disc delivery device 100 according to the present invention only needs to include at least the coin holding container 102, the base 106, the circumferential guide member 108, the rotary disc 110, the regulation member 112, and the ejection device 113. Various modifications having similar actions and effects are possible.

First, the coin holding container 102 will be explained.
The coin holding container 102 has a function of holding the received disk bodies C in a bulk state. , The intermediate portion 102M is formed on a slope connecting the upper portion 102U and the lower portion 102L, and a rectangular flange 102F for attachment is formed at the lower end portion.
A circular container bottom hole 117 having a diameter slightly larger than the diameter of the rotating disc 110 is formed in the lower portion 102L.

Next, the base 104 will be explained.
The base 104 has the function of mounting the base 106 like a ceiling and incorporating the rotation driving device and the control unit of the rotating disk 110. In the first embodiment, the front side F is low and the rear side R is low. It has a high trapezoidal channel shape when viewed from the side. However, the upper surface 104U can also be formed horizontally.

Base 106 will now be described with reference to FIGS.
The base 106 has at least the function of guiding the lower surface of the disc body C that is rotated together by the rotating disc 110 . In the first embodiment, the base 106 is a rectangular flat plate having a predetermined thickness and is fixed to the upper surface 104U of the base 104 that slopes forward downward. In the first embodiment, it is formed in a vertically long rectangular shape in order to guide the disc body C pushed by the rotary disc 110 and to arrange the fixed guide body 114 and the ejection roller 116 . However, as long as the base 106 has the same function, its shape and the like do not matter.

Next, the circumferential guide member 108 will be described with reference to FIG.
The peripheral surface guide body 108 has a function of guiding the peripheral surface of the disk body C that is moved while sliding on the base 106 by the rotating disk 110, and is thicker than the thickness of the disk body C that is assumed to be used. also has a slightly thicker plate thickness. In the present embodiment 1, for example, if the disk C is a one-yen coin, it has a plate thickness of 2.0 mm, which is slightly thicker than the thickness of the disk C of 1.5 mm. That is, a peripheral guide wall 118 having a diameter slightly larger than the diameter of the rotating disk 110 is formed.
A peripheral guide wall 118 serves as a guide surface for the disc body C, and a part of the peripheral guide wall 118 is open to a length equal to or greater than the diameter of the disc body C, forming an outlet opening 122 . Therefore, the peripheral guide body 108 is formed in a C shape as a whole.

Next, the peripheral guide wall 118 will be explained.
The peripheral surface guide wall 118 has a function of guiding the disk body C pushed by the pushing portion 128 (FIG. 2) of the rotating disk 110, more specifically, by the inner pushing portion 128i (FIG. 3). It is a circular hole formed so as to penetrate the guide body 108 from the upper side to the lower side, and its depth is formed slightly deeper than the thickness of the thickest disc body C expected to be used. The diameter of the peripheral guide wall 118 is formed to be substantially the same as the diameter of the rotating disc 110 . Therefore, the peripheral guide wall 118 is a circular hole located outside the pushing portion 128 .

The outlet opening 122 will now be described primarily with reference to FIG.
The outlet opening 122 of the first embodiment is opened with a predetermined length at the lower side of the peripheral guide wall 118 in the inclination direction of the base 106, and the left end 118L and the right end 118R form a space d. . In the first embodiment, the distance d between the left end portion 118L and the right end portion 118R is about twice the diameter of the disk C to be sent out. However, the length of the interval d is sufficient as long as the disc C can pass through and can be ejected by the ejection device 113 .
The rotation axis CS of the rotating disc 110, the central axis of the peripheral guide wall 118 and the central axis of the container bottom hole 117 of the coin holding container 102 are the same.

Next, the rotating disk 110 will be described mainly with reference to FIGS. 2 and 3. FIG.
The rotating disk 110 has a function of rotating together with the rotating disk 110 after separating the disk bodies C one by one, and further pushing in the radial direction of the rotating disk 110. In the first embodiment, at least: It includes a disc-shaped disc main body 124, through holes 126 (126A to 126E) as separation portions 125 formed in the eccentric portion of the disc main body 124, and pushing portions 128 (128A to 128E) formed on the back surface.

First, the disc main body 124 will be explained.
The disc main body 124 is formed by integral molding of metal, wear-resistant resin, or the like, and is fixed to the tip of a rotating shaft 130 that stands upright with respect to the base 106, so that at least the upper portion in the thickness direction holds coins. The pressing part 128 at the lower end of the container 102 is rotated at a predetermined speed inside the peripheral guide wall 118 . In the first embodiment, the rotating shaft 130 is rotated via a speed reducer 133 by an electric motor 131 attached to the back side of the base 106 . Therefore, the axes of the rotating shaft 130 and the rotating disk 110 also coincide with the axis CS. Further, a peripheral guide wall 118 is positioned outside the pushing portion 128 . Since the rotating shaft 130 stands vertically with respect to the base 106 , the rotating disk 110 also tilts forward and downward and rotates in a plane parallel to the base 106 . In other words, the base 106 and the rotating disk 110 are arranged in parallel with a predetermined gap therebetween. The gap is the distance between the lower end of the pressing portion 128 formed on the back surface of the rotating disk 110 (disk main body 124) and the upper surface of the base 106, and the lower end of the pressing portion 128 and the base 106 do not contact each other, When the thickest disk C expected to be used slides on the base 106, a slight gap is formed between the upper surface of the disk C and the rear surface of the disk main body 124. FIG.

Around the rotating shaft 130 on the upper surface side of the disk body 124, a conical agitating portion 132 is formed, and when the rotating disk 110 rotates, the disk bodies C randomly piled in the coin holding container 102 are agitated.
A clearance regulating portion 134 protruding downward in a columnar shape is formed around a rotating shaft 130 on the back side of the disc main body 124, and the lower end of the pushing portion 128 is half the thickness of the thinnest disc C with respect to the base 106. Regulate to keep a distance of one or less and rotate. A sheet made of a low-friction material can be interposed between the lower end surface of the clearance restricting portion 134 and the base 106 in order to reduce frictional resistance.

Next, the through hole 126, which is the separating portion 125, will be described.
The separation unit 125 has a function of separating the disk bodies C bulk-stacked in the coin holding container 102 one by one. In the first embodiment, the separating portion 125 is a circular through hole 126 that vertically penetrates the disk body 124 at an eccentric position of the disk body 124 . In the first embodiment, five through-holes 126 (126A to 126E) are formed. When a combination of numbers and letters is used and no separate explanation is required, only the number 126 is used generically.
The through-hole 126 has a function of stirring the disc bodies C randomly piled in the coin holding container 102 and dropping them into the through-hole 126 one by one, thereby separating the disc bodies C one by one. In the first embodiment, five circular through-holes 126A to 126E are formed at eccentric positions of the disk body 124 at regular intervals. The diameter of the through-hole 126 may be set to a diameter that allows the maximum diameter target disk C to fall smoothly so as to be compatible with two or more disk bodies C, or a specific disk C has the largest diameter. It may have a dedicated diameter that allows it to drop smoothly and be processed.
When formed in this manner, the edge of the clearance restricting portion 134 becomes a petal shape.
On the rear surface between the adjacent through holes 126A to 126E of the disk body 124, there are formed pushing portions 128 (128A to 128E) in the shape of swept-back wings extending toward the peripheral edge.

Next, the pushing portion 128 will be explained.
The pressing portion 128 pushes the disk body C dropped into each of the through holes 126A to 126E by the rotation of the rotating disk 110 into a ring-shaped coin passage 136 ( Fig. 3) has a function of pushing. In the first embodiment, the pushing portion 128 is a projection that protrudes downward from the lower surface of the disk main body 124 and is formed in each through hole 126 so as to radially cross the coin passage 136 . In the following description, since five pressing parts 128 (128A to 128E) are formed, the numerals 128 are denoted by letters A to E for the sake of convenience. and alphabetical combinations are used, and only the number 128 is used generically when no separate explanation is required. Since the configuration of each of the pushers 128A to 128E is the same, the pusher 128A will be described as a representative with reference to FIG.

The pushing portion 128A is composed of at least two of an outer pushing portion 128e and an inner pushing portion 128i. However, pusher 128E can form an intermediate pusher between outer pusher 128e and inner pusher 128i. In this case, the intermediate pusher may become the inner pusher 128i for the outer pusher 128e, and the intermediate pusher may become the outer pusher 128e for the inner pusher 128i. There is

First, the outer pressing portion 128e will be described.
The outer pushing portion 128e has a function of pushing the disk body C between the fixed guide body 114 and the ejection roller 116, and in the first embodiment, it is the back surface of the disk main body 124 and the inner side of the rotating disk 110. It is composed of a downward projection formed at a position radially farther from the axis SC than the pushing portion 128i, and is formed in an arc shape when viewed from the back and extends arcuately along the outer peripheral edge of the corresponding through hole 126E. It is an existing protrusion.

The outer end of the outer pushing portion 128e is located at the periphery of the rotary disc 110. As shown in FIG.
The outer rear end 140A, which is the rear end of the outer pushing portion 128e in the forward rotation direction, has a function of pushing the disk body C when the rotating disk 110 is reversed. It is formed on the outermost edge of 124 and is formed in a pointed shape. This is to draw the disk body C into the peripheral guide wall 118 as much as possible.
The outer pushing portion 128e is formed in a swept wing shape so as to be positioned on the trailing side in the forward rotation direction of the rotating disk 110 as it becomes farther from the axis CS. As a result, the disc body C pushed by the inner pushing part 128i and guided to the exit opening 122 by the inner regulation body 112i and the outer regulation body 112e is pushed between the fixed guide body 114 and the ejection roller . Next, after being further pushed between the fixed guide member 114 and the ejecting roller 116 by the outer pushing portion 128e, the ejecting roller 116 is ejected by the elastic force.

When the disc body C is pushed by the outer pushing part 128e at the exit opening 122, the disc body C receives a force from the outer pushing part 128e toward the radial direction of the rotating disk 110 and is ejected from the fixed guide body 114. It is pushed between rollers 116.
The forward rotation direction of the rotating disk 110 means the rotating direction of the rotating disk 110 in which the disk C can be dispensed (counterclockwise in FIG. 4).

Next, the inner pushing portion 128i will be explained.
The inner pressing portion 128i is a protrusion that protrudes downward from the lower surface of the disc main body 124. In the first embodiment, it has a trapezoidal shape when viewed from the back, and the front side of the rotating disc 110 in the forward rotation direction constitutes the inner front surface. The rear side in the rotational direction constitutes the inner rear end. Therefore, between the outer pressing portion 128e and the inner pressing portion 128i, an arc-shaped outer relief groove 138e centered on the axis CS of the rotary disk 110 is formed so that the outer correcting member 112e can pass therethrough.
The forward rotation direction rear end of the rotating disk 110 of the inner pushing portion 128i is preferably formed flush with the peripheral edge of the through hole 126B. This is because by suppressing the amount of movement of the disk C that has fallen into the through hole 126A as much as possible, it is possible to prevent the disk C from moving violently (irregular movement) and, as a result, to prevent unexpected troubles.
Furthermore, the front surface of the inner pressing portion 128i is formed to extend radially from the axis SC. When the disc body C contacts and is guided by the peripheral guide wall 118 and rotated together, the disc body C is pushed by the inner pushing portion 128i.

Next, the clearance restricting portion 134 will be described.
The gap regulation part 134 has a function of positioning the rotating disk 110 with respect to the base 106 at a predetermined distance. The outer surface flush with the periphery of the through hole 126 and the arcuate convex surface located below the base of the pushing portion 128 form a petal shape as a whole.
An inner escape groove 138i is formed between the clearance restricting portion 134 and the inner pressing portion 128i to allow the inner adjusting member 112i to pass therethrough.

Next, the corrector 112 will be described with reference to FIGS. 3 and 4. FIG.
The regulating body 112 has a function of guiding the disk body C, which is pushed through the coin passage 136 by the inner pushing portion 128i, in the radial direction of the rotating disk 110. As shown in FIG. In the first embodiment, the regulating member 112 is composed of a pair of an inner regulating member 112i and an outer regulating member 112e projecting upward from the base 106 at positions facing the outlet opening 122 in the coin passage 136. As shown in FIG. The inner regulating member 112i and the outer regulating member 112e are arranged at approximately equal intervals between the clearance regulating portion 134 and the fixed guide member 114, and their tip portions pass through the outer escape groove 138e or the inner escape groove 138i, respectively. can do. Since the inner corrector 112i and the outer corrector 112e have the same configuration, the outer corrector 112e will be mainly described as a representative.
The outer regulator 112e is fixed to the free end of a leaf spring 142 fixed to the back surface of the base 106 at one end. The leaf spring 142 is made of spring steel, a springy composite structure, resin, or the like.

The leaf spring 142 has a flat plate shape, one end of which is fixed to the back surface of the base 106 by a screw (not shown), the lower end of the outer regulator 112e is inserted into the hole of the other end, and crimped to stand upright. It is
In the first embodiment, the inner corrector 112i and the outer corrector 112e are made of metal or the like.

Next, the ejection device 113 will be explained.
The ejection device 113 has a function of ejecting the disc body C pushed by the rotating disk 110 in a predetermined direction, and includes at least a fixed guide body 114 arranged at the exit opening 122 and an ejection roller 116. I'm in.

Next, fixed guide body 114 will be described mainly with reference to FIG.
The fixed guide body 114 has a function of guiding the disk body C pushed by the pushing part 128 (outer pushing part 128e) after the disk body C is guided by the regulation body 112. It is arranged on the front side of the rotating disk 110 in the forward rotation direction and attached to the base 106 in a substantially fixed state. In other words, the disk body C is not moved by the pushing force in the normal state by the pushing part 128, but is elastically supported so that it can be retracted when pushed by a larger force. In the first embodiment, the fixed guide body 114 is arranged at a position close to the peripheral edge of the rotating disk 110, but it may be located below the peripheral edge of the rotating disk 110. FIG.
In the first embodiment, the fixed guide body 114 protrudes upward from one end of a lever 146 that is rotatably supported by a fixed shaft 144 that protrudes downward from the back surface of the base 106. It is rotatably attached to a fixed guide support shaft 150 that penetrates through 148 and protrudes upward. By locking the tension spring 156 between the locking projection 152 projecting downward from the tip of the lever 146 and the set screw 154 projecting downward from the back surface of the base 106, the tension spring 156 is rotated counterclockwise in FIG. A turning force is applied to the base 106, and the locking projection 158 protruding downward from the back surface of the base 106 abuts against it to stop the turning. Referring to FIG. 3, the fixed guide 114 is urged by a tension spring 156 so as to be rotatable toward the ejection roller 116, but by a locking projection 158, as shown in FIG. It is held in the stationary position SP. In other words, the fixed guide 114 can move leftward in FIG. 3 against the elastic force of the tension spring 156, but cannot move in the opposite direction. The tension spring 156 is much larger than the elastic force of a spring 168, which will be described later, and is substantially maintained in a fixed state when the disk C is normally delivered. However, if pushed by excessive force, it can be displaced, preventing excessive force from being exerted on the rotating disk 110 .

Next, the ejection roller 116 will be described mainly with reference to FIGS. 6 to 10. FIG.
The ejection roller 116 has a function of sandwiching the disk body C between itself and the fixed guide body 114 and ejecting it. In Embodiment 1, the ejection roller 116 is unitized and configured as an ejection roller unit 160 .
The ejection roller unit 160 attaches the ejection roller 116 to a predetermined position on the base 106, adjusts the positional relationship with the fixed guide body 114, and prevents the biasing force from being changed even if the position is adjusted. have a function. In the first embodiment, the ejection roller unit 160 includes a bracket 162, a swing shaft 164, a swing lever 166, a spring 168, a stopper 172, and a position adjusting portion 174.

First, the bracket 162 will be explained.
The bracket 162 has a function to which a swing shaft 164, a swing lever 166, a spring 168, a stopper 172 are attached, and a position adjusting portion 174 is configured. In the first embodiment, the bracket 162 is formed by sheet metal working. The bracket 162 has a flat plate shape, and is integrally formed with a base portion 178 having a roughly trapezoidal shape in plan view, an ejection spring receiving projection 182 projecting downward from the base portion 178, and a stopper support piece 184. As shown in FIG. Further, a circular lever shaft hole 186 formed near one side of the bracket 162, an arc elongated hole 188 forming a part of the position adjusting portion 174 formed around the axis of the lever shaft hole 186, and a lever shaft hole A generally square ejection roller hole 192 formed on the opposite side of 186 is formed.

Next, the swing shaft 164 will be explained.
The rocking shaft 164 has a function of supporting the rocking lever 166 so as to be rotatable.
In the first embodiment, the swing shaft 164 is a downward shaft whose one end is inserted into a lever shaft hole 186 formed near one side of the base portion 178 and then fixed by caulking. A circular positioning hole 194 having a predetermined depth is formed at the crimped end of the swing shaft 164 . A positioning shaft 200 protruding downward from the base 106 is inserted into the positioning hole 194 . The positioning shaft 200 can be replaced by a screw or the like screwed into the base portion 178 .

Next, the rocking lever 166 will be explained.
The rocking lever 166 has a function of supporting the ejection roller 116 so as to be rotatable. In the first embodiment, the rocking lever 166 is made of an elongated plate-shaped sheet metal, and a cylindrical bearing 196 protruding downward is fixed to one end of the rocking lever 166 . Specifically, the upper end of the bearing 196 is inserted into a circular mounting hole 170 formed at one end of the swing lever 166 and fixed. Bearing 196 is rotatably supported by ball bearing 198 on swing shaft 164 .

A plurality of first ball bearings 198A and second ball bearings 198B are built in the bearing 196. A collar 202 is arranged above the first ball bearing 198A, and a resin ring-shaped spacer 204 is arranged above it. be done.
A ring-shaped spacer 206 made of resin is arranged below the second ball bearing 198B on the lower side, and a snap ring 208 is engaged with the tip (lower end) of the swing shaft 164 so that it does not come off the swing shaft 164. supported by
In other words, the swing lever 166 is rotatably supported on the swing shaft 164 by the ball bearing 198 .

A spring engaging portion 210 is formed to protrude downward from the other end of the swing lever 166 . A support shaft 212 (hereinafter referred to as “ejection roller support shaft 212” for convenience) protruding upward from the side of the spring locking portion 210 is fixed.
The ejection roller support shaft 212 is composed of a lower large diameter portion 212L and an upper small diameter portion 212S. The ejection roller 116 is rotatably attached to the small diameter portion 212S via a ball bearing (not shown). A snap ring 216 is placed above a ring-shaped spacer 214 placed above the delivery roller 116 and is locked to the upper end of the small diameter portion 212S to restrict movement in the thrust direction so that it does not come off. When the swing lever 166 is attached to the bracket 162 , the ejection roller 116 passes through the ejection roller hole 192 and is arranged above the bracket 162 .

A generally rectangular contact piece 211 is formed downward from a portion near the swing shaft 164 on the side opposite to the spring locking portion 210 of the swing lever 166 . The contact piece 211 has a function of contacting the stopper 172 and restricting movement when the rocking lever 166 is rotated by the spring 168 . Therefore, the contact piece 211 may be part of the swing lever 166 .

A stopper 172 is fixed to a stopper support piece 184 projecting downward from the end of the ejection roller hole 192 on the ejection spring receiving projection 182 side at right angles to the bracket 162 . The stopper 172 will be described later.

Spring 168 will now be described.
The spring 168 has a function of biasing the rocking lever 166 in a predetermined direction with a predetermined force. Specifically, it has a function of urging the ejection roller 116 to the opposite side with respect to the fixed guide body 114 . Spring 168 is a concept that includes members with similar functions, such as rubber and gas springs.
In the first embodiment, the spring 168 is locked at one end by the ejection spring receiving projection 182 and at the other end by the spring locking portion 210, and finally moves the ejection roller 116 toward the fixed guide body 114. It is energized with rotational force. The spring 168 is set to be smaller than the elastic force of the tension spring 156, and when the disk body delivery device 100 normally operates, the elastic force of the tension spring 156 pushes the disk C out.

Next, the stopper 172 will be explained.
The stopper 172 has the function of stopping the rotation of the swing lever 166 by the spring 168 and restricting the distance between the ejection roller 116 and the fixed guide member 114 to a predetermined distance. In other words, the stopper 172 has the function of receiving the contact piece 211 while buffering it through surface contact and stopping it at a predetermined position.
In Embodiment 1, the stopper 172 is formed in a ring shape from resin that does not substantially hydrolyze. Engineering plastics are preferred as the resin.
Engineering plastics are excellent in mechanical strength, for example, shock resistance, so they are highly durable against repeated impacts from the contact piece 211 of the rocking lever 166. In addition, since they have a high bending elastic modulus, they absorb shocks to the contact piece 211. Since it is highly elastic, it has the advantage of having a small amount of bounce.
In the present specification, engineering plastics must have a tensile strength of 50 MPa or more at room temperature and a bending elastic modulus of 2.4 GPa or more at room temperature, and in the present invention, must be substantially non-hydrolyzable. be. Specifically, as the substantially non-hydrolyzable resin that can be used in the present invention, polyacetal resin, polycarbonate resin, modified polyphenylene ether resin, polyamide resin, or ultra-high molecular weight polyethylene resin are assumed. The term “substantially non-hydrolyzable” means that the composition does not become sticky even when used in high humidity.

Next, the stopper 172 will be described mainly with reference to FIGS. 9 and 10. FIG.
In the first embodiment, the stopper 172 is made of polyacetal resin and has a predetermined thickness, for example, 1 mm, and a predetermined diameter, for example, 8 mm. ing. The through hole 218 is formed by a cylindrical hole 218P and a conical hole 218C connected to the cylindrical hole 218P. Cylindrical hole 218P is approximately 4 mm in diameter, and conical hole 218C is a conical hole having an angle A of 90 degrees inclined at an angle of 45 degrees left and right with respect to centerline CL.

上記より、実施例１における、ポリアセタール樹脂によって製造したストッパ172が加水分解による悪影響が長期に亘り生じないので最も適した材料であると言える。 Next, one test example of the stopper 172 made of polyacetal will be described.
In the test, the sample was subjected to a temperature and humidity cycle test in which a high temperature and high humidity state and a low temperature and low humidity state were repeated, and the sample was evaluated by measuring the hardness and observing the appearance for each cycle.
The temperature-humidity cycle test is a test in which the following high-temperature, high-humidity environment and low-temperature, low-humidity environment are repeated to accurately create dew condensation and dry conditions in the sample, and to evaluate hydrolysis at an accelerated rate.
Specifically, the contents of the temperature-humidity cycle test consisted of placing a sample in a test room and repeating the following procedures 1 to 4 as one cycle.
1. The high temperature and high humidity environment is left for 3 hours in an environment with a temperature of 60°C and a humidity of 90%.
2. Leave for 1 hour before switching from the high-temperature and high-humidity environment to the low-temperature and low-humidity environment.
3. The low temperature and low humidity environment is left for 3 hours in an environment with a temperature of -20°C and a humidity of 0%.
4. Leave for 1 hour before switching from low temperature and low humidity environment to high temperature and high humidity environment.
The shape of the sample used for the test is the shape shown in FIG. The material of the sample of Comparative Example 1 is an ester-based urethane rubber containing an ester bond in its main chain. For the material of the sample of Comparative Example 2, an ether-based urethane rubber containing an ether bond in the main chain was used. The material of the samples of the examples is polyacetal resin.
Comparative Example 1: Ester-based urethane rubber, initial hardness 80
Comparative Example 2: Ether-based urethane rubber, initial hardness 80
Example 1: Polyacetal resin, initial hardness 90
As a method for evaluating hardness, hardness was measured with a type A durometer that satisfies the measuring instrument conditions specified in JIS K 6253, and the rate of change from the initial value was obtained.
In the appearance observation, the appearance of the stopper was observed, and the surface conditions such as the presence or absence of viscous substances, the presence or absence of cracks, the restorability of dents, and the presence or absence of collapsing of corners were observed.
Table 1 below shows the test results.

In Table 1, the evaluation in some cycles is omitted, and the evaluation in the cycle is in a state of no change from the previous evaluation.
The evaluation "◯" means that no abnormality is found on the surface of the sample in the observation of appearance. The state in which no abnormality is found on the surface means the state in which there is no viscous matter, good restorability, and no cracks or collapses. When the hardness in this case was measured, it was within the range of 100 to 75% of the initial hardness. As the test progressed, the deterioration progressed, but if the hardness was 75% or more compared to the initial value, the sample had no problems in terms of appearance and functionality. A viscous substance is an intermediate product produced during the process of hydrolysis of a sample reacting with water or a product after hydrolysis, and is a viscous substance. A state of good restorability means a state in which no trace remains when the sample is pressed with a durometer.
The evaluation "Δ" means that there is a viscous substance on the surface of the sample, or there is an abnormality such as a mark left by pressing with a durometer pin. When the hardness in this case was measured, it was within the range of 74 to 58% compared to the initial value. If the deterioration of the sample progresses and the hardness is within this range, the sample may have problems in terms of appearance and function. The state in which a pin-pressed mark remains is a state in which when a sample is pressed with a durometer, the pressed mark does not return immediately and a mark remains.
An evaluation of "x" indicates that there is an abnormality on the surface in the observation of appearance. The state in which the surface of the sample is abnormal is, for example, a state in which cracks appear on the surface or collapse is observed at the corners. When the hardness in this case was measured, it was within the range of 57 to 43% compared to the initial value. Degradation of the sample progresses, and problems occur in the appearance and functionality of the sample. A problem arises when the hardness is 57% or less compared to the initial value.
In observing the external appearance of cycle 9 of Comparative Example 1, a viscous material was observed on the surface of the sample, so the evaluation was given as "Δ".
In cycle 12 of Comparative Example 1, a viscous material was observed on the surface of the sample, and when the contact piece 211 was brought into contact with the surface of the sample, the contact piece 211 adhered to the sample and a load was generated due to peeling off. , the evaluation was set to "x".
In the external appearance observation of cycle 15 of Comparative Example 2, it was judged that the restorability was deteriorated and the mechanical strength was degraded because the traces of pressing with the pin remained, and the evaluation was given as "Δ". Ether-based urethane rubber does not have an ester bond, so it is considered to be difficult to hydrolyze, but deterioration progresses little by little, and strength decreases. Although it is not clear, the cause may be cleavage of the urethane bond, hydrolysis of the urethane bond, or the like.
Also, the judgment as to whether or not the sample can be used as the stopper 172 is as follows.
If the evaluation is "◯", it can be preferably used.
If the evaluation is "△", it may cause problems and cannot be used.
If the evaluation is "x", it causes a problem and cannot be used.
From the above, it can be said that the stopper 172 made of polyacetal resin in Example 1 is the most suitable material because it is not adversely affected by hydrolysis over a long period of time.

The stopper 172 is fixed to the stopper support piece 184 by the countersunk screw body 222 . The end face of the stopper 172 on the side of the cylindrical hole 218P is applied to the stopper support piece 184, and the threaded portion 222S of the countersunk screw body 222 is threaded from the conical hole 218C to the cylindrical hole 218P and then to the stopper support piece 184. It is fixed by a nut 226 screwed onto a threaded portion of a countersunk screw body 222 through a hole 224 . By tightening the nut 226, the screw portion 222S is axially moved, and the conical surface 222C of the screw head 222H of the countersunk screw body 222 is pressed against the conical hole 218C. Thus, in the stopper 172, the hit portion 176 with which the contact piece 211 of the swing lever 166 contacts is formed into a circular ring-shaped surface. By forming the stopper 172 into a ring shape, the hit part 176 becomes a ring-shaped surface, which reduces the area and facilitates manufacturing. Since the stopper 172 is made of resin and has a predetermined elasticity, the reaction force tightened by the nut 226 acts on the conical surface 222C of the countersunk screw body 222 from the conical surface of the conical hole 218C. , a force acts in the axial direction of the countersunk screw body 222 . As a result, a force in the thrust direction acts between the female thread of the nut 226 and the male thread of the threaded portion 222S, and the locking effect of the nut 226 is obtained.

Next, the position adjusting section 174 will be explained.
The position adjuster 174 has a function of adjusting the position of the ejection roller 116 with respect to the fixed guide member 114 . In Embodiment 1, the position adjusting portion 174 is composed of an arcuate long hole 188 centered on the axis of the lever shaft hole 186 and a set screw 228 . The setscrew 228 has the function of holding the bracket 162 in a fixed state by frictional force by being passed through the arcuate long hole 188 and screwed into the back surface of the base 106 .

Next, a method of attaching the ejection device 113 to the back surface of the base 106 will be described.
The ejection device 113 inserts the positioning shaft 200 protruding from the back surface of the base 106 into the positioning hole 194, brings the upper surface of the bracket 162 into close contact with the back surface of the base 106, and screws the set screw 228 into the base 106. Fixed in place. The predetermined position means that the distance between the ejection roller 116 and the fixed guide body 114 is set to a position suitable for the diameter of the disc body C. As shown in FIG. When adjusting the position of the ejection roller 116, after loosening the set screw 228, rotate the bracket 162 around the positioning shaft 200, and tighten the set screw 228 again at an appropriate position.

Since the stopper 172 is hit by the contact piece 211 a great number of times each time, it needs to be highly durable so as not to cause problems such as cracking. Therefore, an example of the method of manufacturing the stopper 172 in the first embodiment will be described with reference to FIG.
As shown in FIG. 4A, in the first embodiment, the material of the stopper 172 is a round bar material 234 obtained by drawing a polyacetal resin into a standardized predetermined diameter. Injection molding of engineering plastics is more difficult than general-purpose resins, and mold temperature control is required. Poor temperature control, etc. may cause the resins to not adhere to each other at the confluence of the resins, resulting in a boundary (weld). , cracks may occur starting from the boundary. However, a drawn round bar is preferred because it does not create such a boundary and there is no risk of cracking from the boundary. In other words, it is preferable to use a polyacetal resin round bar material 234 having a standardized outer diameter and length.
Next, as shown in FIG. 4B, a round bar material 234 is attached to the chuck of the lathe, a small diameter drill 236 is attached to the end surface of the round bar material 234, and a circular hole 238 that becomes a cylindrical hole 218P is formed in the center. to perforate.
Next, as shown in FIG. 1(C), a large-diameter drill 242 is applied to the end surface of the circular hole 238 and countersinked to form a conical hole 244 with a predetermined depth that will become the conical hole 218C. .
Next, as shown in FIG. 4D, the round bar material 234 is cut by a cut-off tool 240 at a predetermined length LS (corresponding to the thickness of the stopper 172) from the end surface of the round bar material 234 to form the stopper 172. do.

Next, the disc-shaped sensor 230 will be described mainly with reference to FIG. 2 or FIG.
The disk body sensor 230 has a function of detecting the disk body C ejected by the fixed guide body 114 and the ejection roller 116, and is arranged in relation to the movement path of the ejected disk body C. A sensor or the like can be employed. A metal sensor is used in the first embodiment. The disk-shaped sensor 230 includes, for example, a sensor bracket 246, a U-shaped sensor body 248, and a sensor coil 250 and detection circuit (not shown).
The sensor body 248 is formed into a U-shape by an upper crosspiece 248U and a lower crosspiece 248L arranged vertically at a predetermined interval, and a post 248P connecting one ends of the upper crosspiece 248U and the lower crosspiece 248L. and the lower crosspiece 248L, the disk body C pushed out by the fixed guide body 114 and the ejection roller 116 passes through the sensor coil 250 portion. A change in the electric current flowing through the sensor coil 250 due to the metallic disk C is detected, and ejection of the disk C is detected. Sensor body 248 is secured to base 106 by sensor bracket 246 .

Next, the operation of the first embodiment will be explained.
The disc bodies C held in the coin holding container 102 are stirred by the rotation of the rotating disk 110 and take various postures, so that they fall one by one into the through holes 126 (126A to 126E). The disk body C dropped into the through-hole 126 comes into surface contact with the base 106, is pushed by the inner pushing part 128i, and is guided along the outer circumferential surface by the circumferential surface guide wall 118, and is moved along the coin passage 136 by the rotating disk 110. It is taken around (Fig. 3).
When the disc body C is pushed toward the regulating body 112, it is first guided by the inner regulating body 112i toward the exit opening 122, in other words, in the radial direction of the rotary disc 110 (FIG. 3), and then is guided toward the outer regulating body 112e. is guided in the radial direction of the rotating disk 110 by (FIG. 4).

As a result, a part of the circular arc peripheral surface of the disc body C is guided in contact with the fixed guide body 114, the disc body C as a whole is guided toward the ejection roller 116 side, and the arc peripheral surface on the other side is guided to the ejection roller 116 side. Make contact with 116. In this process, the pressing portion 128 of the disc body C changes from the inner pressing portion 128i to the outer pressing portion 128e. Since the disc body C is further pushed in the radial direction of the rotary disc 110 by the outer pushing part 128e, the ejection roller 116 is separated from the fixed guide body 114. As shown in FIG. Until the ejection roller 116 is moved by the disk C, it is kept stationary with a predetermined distance equal to or less than the diameter of the disk C from the fixed guide body 114, and the contact piece of the rocking lever 166 is kept stationary. 211 is brought into surface contact with the hit portion 176 of the stopper 172 by the elastic force of the spring 168 and is pressed.
When the ejection roller 116 is moved by the disk C, the swing lever 166 is rotated clockwise in FIG. 4 against the elastic force of the spring 168 . By rotating the rocking lever 166 clockwise, the contact piece 211 is separated from the stopper 172 (hit portion 176).

When the disc body C is pushed between the fixed guide body 114 and the ejection roller 116 by the outer pushing portion 128e, the ejection roller 116 moves away from the fixed guide body 114 against the elastic force of the spring 168. 4, the center of the disk C crosses the straight line L connecting the point of contact P1 between the disk C and the fixed guide body 114 and the point of contact P2 between the disk C and the ejection roller 116. Immediately after this, the fixed guide body 114 and the ejecting roller 116 each contact the arcuate surface of the disk body C on the backward side in the traveling direction, so that the ejecting roller 116 is moved by the elastic force of the spring 168 to the fixed guide body 114. It is moved to the side and ejected in a direction away from the rotating disk 110 . As the ejection roller 116 moves toward the fixed guide body 114, the rocking lever 166 rotates counterclockwise in FIG. is restrained and becomes stationary. Since resin has a lower hardness than metal, microvibrations due to rebounding quickly converge. Also, since the density is much lower than that of metal, the impact sound is greatly reduced. Moreover, since it is a resin that does not substantially hydrolyze, there is an advantage that even when used under high humidity conditions, it does not become sticky and does not cause erroneous detection or ejection failure.

Also, the height H2 of the second deformation prevention ring 2562 is set lower than the height (thickness) H3 of the stopper 172 . As a result, the contact piece 211 comes into contact with the hit portion 176 of the stopper 172, suppressing radial deformation of the stopper 172 due to multiple hits by the contact piece 211, thereby improving durability. Moreover, it is preferable that the height H2 of the second deformation prevention ring 2562 is set higher than the height H1 of the screw head 222H of the countersunk screw body 222 . As a result, even if the stopper 172 is deformed and the height H3 is reduced, the contact piece 211 contacts the deformation prevention ring 256, so that the head of the countersunk screw 222 can be prevented from being hit. Because you can. The second anti-deformation ring 2562 can be fixed to the stopper support piece 184 or press-fitted to the stopper 172 .

A portion is formed in the circular flat portion 258 . The lower surface of the stopper 172 is in contact with the flat portion 258 and fixed by the countersunk screw body 222 . As a result, the lower end of the stopper 172 is fitted inside the third deformation prevention ring 2563 . Therefore, when the lower end portion of the stopper 172 is deformed to swell, it is restricted by the third deformation prevention ring 2563, so there is an advantage that the deformation of the stopper 172 is suppressed. The ring body of the third deformation prevention ring 2563 may be fixed to the stopper support piece 184 by brazing or the like.

Next, Embodiment 4 will be described with reference to FIG.

It has a bottom portion 264 and is formed in a bottomed pan shape having a bottom hole 266 with a predetermined diameter smaller than that of the circular ring portion 262 .
