Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a coin sorting device that sorts inserted coins into denominations, which are components of a coin processing device mounted on a vending machine or the like.
[0002]
[Prior art]
A coin processing device is installed to process coins inserted when purchasing merchandise from vending machines, and this coin processing device is equipped with a coin distribution device that distributes coins by denomination. . Each sorting unit of this coin sorting device sorts inserted coins into fake coins, 50 yen coins, 10 yen coins, 100 yen coins, 500 yen coins, and stores them in various coin tubes and safes, or in return slots. return.
[0003]
As the type of each sorting unit, there are known a type in which a rotary flapper is rotated by a solenoid, and a type in which a split piece bifurcated upwards is moved up and down by a solenoid before and after the coin path surface. (Japanese Patent Laid-Open No. 4-40754).
[0004]
In this latter sorting part, each sorting piece is arranged in the front and back, and its lower end is fixed, and the rear sorting piece is connected to a solenoid via a connecting member.
[0005]
Here, when the solenoid is in a non-excited state, an inserted coin (for example, a 10-yen coin) falling from above is received by the rear sorting piece, and is distributed to a 10-yen coin tube. On the other hand, when the solenoid is in an excited state, the sorting unit is pulled to the rear of the coin passage, and a coin (for example, 50 yen) is received by the front sorting piece, which is sorted to a 50-yen coin tube.
[0006]
[Problems to be solved by the invention]
However, in the latter sorting portion, each sorting piece made of resin is only fixed at the lower end thereof, so that it does not have a sufficient receptive strength against a coin drop impact. Therefore, when used over a long period of time, the sorting piece is deformed, and the coin processing cannot be performed smoothly. In addition, the delay of the coin processing has a problem that coins that are continuously dropped are brought into contact with each other and the coins are jammed.
[0007]
On the other hand, in order to improve the strength of each sorting piece, there is also a solution method such as making the sorting piece itself thick, but this is not adopted in a coin sorting apparatus that requires a large sorting part and severe space efficiency. This is the solution.
[0008]
Further, since the fixed end of each sorting piece is only the lower end, the elastic force of each sorting piece acts on the whole from the lower end to the upper end of each sorting piece. Therefore, when a falling coin collides with each sorting piece, the coin is greatly bounced upward by the elastic force of the sorting piece, and this also collides with a succeeding coin and causes a coin jam.
[0009]
An object of the present invention is to provide a coin sorting device that has sufficient strength against an impact on a dropped coin and can prevent coin clogging in view of the conventional problems.
[0010]
[Means for Solving the Problems]
In view of the above-described conventional problems, the present invention has a sorting portion in which a pair of front and rear sorting pieces are fixed to each other at their lower ends and bifurcated upward, and each sorting piece is passed through a coin. In a coin sorting device that divides and throws in and out the front and back of a road surface and sorts inserted coins that fall on each sorting piece in two directions, the rear sorting piece is fixed to a connecting plate that connects to a drive source, and the rear sorting piece and the connecting plate fixation area is larger than the fixation area of the lower ends of each distribution piece has a small Kushida structure than a coin receiving angle of the coin receiving angle rear distributing pieces of the front distributing pieces with.
[0011]
According to the present invention, since the fixing area of the rear distribution piece is large, the strength of the distribution piece is reinforced by the connecting plate. Further, the elastic force of the rear sorting piece is reduced by the amount of the fixing area with the connecting plate, and when the falling coin collides with the sorting piece, the upward movement is also reduced.
[0012]
On the other hand, the front distribution piece is inferior in strength to the rear distribution piece and has a larger elastic force. However, the coin receiving angle of the front distribution piece is made smaller than the coin receiving angle of the rear distribution piece. Yes. Therefore, the impact of the coin falling on the front sorting piece is weak, and the resilience associated with the drop impact is also small.
[0013]
As in the second aspect of the present invention, a plurality of distribution units may be integrally connected by a connecting plate, and the plurality of distribution units may be operated by a single drive source.
[0014]

It is explanatory drawing.
[0015]
First, a schematic configuration of the coin processing apparatus will be described with reference to FIGS. 1 and 2. That is, this coin processing device is mounted on, for example, a vending machine, and has a coin identifying unit 10 for identifying coins inserted from the insertion slot 1 (10 yen coin, 50 yen coin, 100 yen coin, 500 yen coin). The coin distributing unit 20 that distributes the coins identified by the coin identifying unit 10 and the coin storage unit 30 that stores the coins distributed by the coin distributing unit 20 perform money processing on purchased products. .
[0016]
The coin identifying unit 10 normally transmits a signal of a predetermined frequency to the inserted coin, and based on the change of the received frequency, the type of a true coin, a fake coin, and a 10 yen coin, a 50 yen coin, a 100 yen coin, and a 500 yen coin Has been identified.
[0017]
The coin sorting unit 20 includes first to eighth sorting units 201 to 208 from the upper side to the lower side of coin rolling.
[0018]
Here, the 1st distribution part 201 rotates the rotation flapper 201a with solenoid SC1, returns a false coin to the return port which is not shown in figure, and falls a genuine coin toward the 2nd distribution part 202. FIG. Thus, the 1st distribution part 201 has the function to distribute based on the truth of inserted coin.
[0019]
As shown in FIGS. 3 (a) and 3 (b), the second distribution unit 202 uses 100 yen coins, other 10 yen coins, and 50 yen coins determined to be the correct coins by the first distribution unit 201. And 500 yen coins. The second sorting section 202 has front and rear sorting pieces 202a and 202b that are bifurcated, and is made to appear and disappear from the coin path A by a solenoid SC2. When the solenoid SC2 is de-energized (OFF), as shown in FIG. 3A, the 10-yen coin, 50-yen coin, and 500-yen coin are rolled to the rear sorting piece 202b to generate the third sorting unit. Guide to 203. On the other hand, in the excited state (ON), as shown in FIG. 3 (b), the second sorting unit 202 is pulled rearward, thereby causing the 100-yen coin to fall onto the front sorting piece 202a. Guidance is directed toward the four distribution unit 204.
[0020]
The third distribution unit 203 distributes the 10-yen coin, 50-yen coin, and 500-yen coin distributed by the second distribution unit 202. The third distribution unit 203 rotates the rotation flapper 203a to introduce 500 yen coins into the inside, while dropping 10 yen and 50 yen toward a seventh distribution unit 207 described later. The third sorting unit 203 has a first temporary holding unit 211 that temporarily holds 500 yen coins at its tip, and the third sorting unit 203 includes a first temporary holding unit 211 that appears and disappears from the coin path A. 2 temporary holding sections.
[0021]
The fourth sorting unit 204 rotates the rotary flapper 204a with the solenoid SC4, guides the 100 yen coin to the safe passage B (the back side of the rotary flapper 204a) and introduces it into the safe (not shown), while rotating the 100 yen coin. It is made to roll to the surface side of the flapper 204a, and to drop toward the 6th distribution part mentioned later.
[0022]
The fifth sorting unit 205 includes a return path C and a coin storage unit (safe passage) that communicate the 500 yen coins that have been rolled through the third sorting unit 203 and the temporary holding units 211 and 212 to a return port (not shown). B and 500 yen coin tube CT500), and the rotation flapper 205a is rotated by the solenoid SC5 for distribution.
[0023]
The sixth distribution unit 206, the seventh distribution unit 207, and the eighth distribution unit 208 are controlled by a solenoid SC6, and are integrally formed with a connecting plate 209 that is connected to the solenoid SC6.
[0024]
First, the sixth distribution unit 206 will be described with reference to FIGS. 5 and 6A and 6B. The sixth distribution unit 206 distributes the 100 yen coins distributed by the fourth distribution unit 204 to the coin tube CT100 for 100 yen and the empty tube CT0. The sixth distribution unit 206 is made of resin and has front and rear distribution pieces 206a and 206b that are bifurcated. The lower end of each of the distribution pieces 206a and 206b is fixed to be substantially Y-shaped. Further, the coin passage A has through holes 206c through which the respective sorting pieces 206a and 206b are inserted, and the sorting pieces 206a and 206b are reciprocated back and forth through the through holes 206c by the excitation / non-excitation of the solenoid SC6. It has become.
[0025]
Here, when the solenoid SC6 is not energized (OFF), as shown in FIGS. 4A and 6A, 100-yen coins are rolled to the rear sorting piece 206b to be coin tubes CT100. Drop and store in On the other hand, in the excited state (ON), as shown in FIG. 4B and FIG. 6B, the connecting plate 209 is pulled backward, whereby 100-yen coins fall onto the front sorting piece 206a. And drop and store it in the empty coin tube CT0.
[0026]
Further, when compared with the fixing portion (Wb2 in FIG. 5) at the lower end of each sorting piece 206a, 206b and the fixing portion (Wa2 in FIG. 5) between the connecting plate 209 and the rear sorting piece 206b, the width of the connecting plate 209 is obtained. , Wb2 <Wa2. As described above, the attachment strength of the rear distribution piece 206b is higher than the attachment strength of the front distribution piece 206a because the fixing area of the rear distribution piece 206b is large.
[0027]
Furthermore, the resilience of each of the sorting pieces 206a and 206b increases as the length of the unfixed portion increases. Here, the non-fixed portion, that is, Wb1 in FIG. 5 for the front distribution piece 206a and Wa1 in FIG. 5 for the rear distribution piece 206b, and both of them satisfy Wb1> Wa1, so the elasticity is The front distribution piece 206a is larger than the side distribution piece 206b.
[0028]
Furthermore, as shown in FIG. 6, 100-yen coins fall from above the sixth sorting unit 206, but the impact load of each sorting piece 206a, 206b against the coin drop varies greatly depending on the coin receiving angle (θ1, θ2). To do. That is, when the coin receiving angle is small, the impact load is small, and when it is large, the impact load is large. Here, the coin receiving angle of the front distributing piece 206a is θ2, while the coin receiving angle of the rear distributing piece 206b is θ1, and θ2 <θ1. That is, the impact load of the front distribution piece 206a is smaller than the impact load of the rear distribution piece 206b.
[0029]
The seventh distribution unit 207 distributes the 10 yen / 50 yen coins distributed by the third distribution unit 203 to the coin tube CT10 for 10 yen and the coin tube CT50 for 50 yen.
[0030]
The seventh sorting unit 207 has the same structure as the sixth sorting unit 206 described above, and causes the front and rear sorting pieces 207a, 207b branched and forked from the coin passage A through the through-hole 207c, and is used as a solenoid SC6. Is de-energized (OFF), as shown in FIGS. 4A and 6A, the 10-yen coin is dropped onto the rear sorting piece 207b and dropped and stored in the coin tube CT10. On the other hand, as shown in FIG. 6B, in the excited state (ON), the connecting plate 209 is pulled backward as shown in FIG. 4B and FIG. , 50 yen coins are dropped onto the front sorting piece 207a and dropped and stored in the coin tube CT50.
[0031]
Each distributing member 207a, when compared to 207b fixing portion Wd2 the connecting plate 209 and the rear side distributing piece 20 7 b of the fixing portion Wc2, as shown in FIG. 5, has a Wd2 <Wc2. On the contrary, when comparing the non-fixed portions of the respective sorting pieces 207a and 207b, as shown in FIG. 5, Wd1> Wc1, and the front side of the rear sorting piece 207b as in the sixth sorting unit 206. The resilience of the sorting piece 207a is greater. Further, as shown in FIG. 5, the coin receiving angle of the front distributing piece 207a is θ4, while the coin receiving angle of the rear distributing piece 207b is θ3, and θ4 <θ3. Therefore, the front distributing piece 20 It is smaller than the impact load of the rear distributing piece 20 7 b is an impact load of 7 a.
[0032]
The eighth sorting unit 208 sorts 500 yen coins into the safe passage or the coin tube CT500, and has bifurcated guide partition walls 208a and 208b extending in parallel toward the tip as shown in FIG. Each guide partition 208a, 208b has a coin sliding surface obliquely inward, and 500 yen coins are guided to the outlet 208c at the center of the bottom surface by the coin sliding surface. Here, when the solenoid SC6 is not excited (OFF), the 500 yen coin is guided to the coin tube CT500, while when the solenoid SC6 is in the excited state (ON), the 500 yen coin is guided to the rear safe passage B.
[0033]
In the coin sorting apparatus configured as described above, the sorting pieces 206a, 206b, 207a, and 207b of the sixth sorting unit 206 and the seventh sorting unit 207 have a fixed area of Wb2 <Wa2 and Wd2 <Wc2 as described above. (Strength of each sorting piece), Wb1> Wa1 and Wd1> Wc1 (elastic force of each sorting piece) for the non-fixed portion, θ2 <θ1 and θ4 <θ3 (impact load on each sorting piece) for the coin receiving angle It has become each.
[0034]
That is, the coin receiving angles of the rear sorting pieces 206b and 207b are increased (θ1, θ3), and as shown in FIGS. 6A and 6B, the coin tubes CT10, Even when coins are stored in the CT 100 (L1> L2, L3> L4), the rear distribution pieces 206b and 207b have high strength, so that the rear distribution pieces 206b and 207b are deformed or damaged. There is nothing to do.
[0035]
Further, since the non-fixed portions of the rear distribution pieces 206b and 207b are small, the elastic force of the rear distribution pieces 206b and 207b is small. Thereby, the falling coins are not bounced greatly by the sorting pieces 206b and 207b and are smoothly stored in the respective coin tubes CT10 and CT100, so that coin clogging due to contact with the subsequent falling coins can be prevented.
[0036]
On the other hand, the strength of the front distribution pieces 206a and 207a is lower than that of the rear distribution pieces 206b and 207b, and the elasticity of the front distribution pieces 206a and 207a is higher than that of the rear distribution pieces 206b and 207b. , The coin receiving angle is reduced (θ2, θ4). As a result, the impact load due to the dropped coin is small, the front sorting pieces 206a, 207a are not deformed or damaged, and the fall coins are small and are smoothly stored in the coin tubes CT50, CT0.
[0037]
【The invention's effect】
As described above, according to the present invention, the rear sorting piece can be firmly attached to the connecting plate so as to have a sufficient strength against the falling coins, and the front sorting piece has a smaller coin receiving angle. Since the impact load caused by the falling coins is reduced, each sorting piece is not deformed or damaged.
[0038]
In addition, the expansion of the fixed area and the narrowing of the coin receiving angle can simultaneously reduce the resilience of each sorting piece, so that inserted coins are smoothly stored in the coin tube, preventing coin clogging. it can.
