Description

[Detailed description of the device] [Industrial field of application] This device mixes multiple types of coins and deposits them all at once.
The present invention relates to a sorting device for a coin processing machine, which sorts and counts money types.

[Conventional technology]

FIG. 3 is a plan view showing a conventional technique, and FIG. 4 is an IV of FIG.
It is a IV-IV cross-sectional view.

In the drawing, the mixed coins M put into the hopper 1 are separated one by one by the centrifugal force generated by the rotation of the disk 2 and the outlet gap control section 3 of the hopper 1 and sent out to the coin conveying passage 4 from between the guides 9 and 10. Be done. The coin M sent out to the coin carrying path 4 is carried in the direction of arrow B by the belt 7 hung on the pulleys 5 and 6. The pulleys 5 and 6 receive power from a motor (not shown) and rotate. When the coin comes into contact with the slope 91 of the guide 9 protruding above the surface of the coin transport passage 4, the rubber roller 8 changes the direction in the direction of arrow C to be transported and enters the transport passage 11. The rubber roller 8 rotates by receiving power from a motor and a belt (not shown).

A belt 15 wound around a pulley 13 and a driven pulley 14 attached to a drive shaft 12 that receives power from a motor (not shown) is stretched in the transport passage 11. The driven pulley of this belt 15
From the 14 side, coins are transported in the transport path 11 in the direction of arrow D.
The shaft center of the drive shaft 12, that is, the shaft center of the pulley 13 is fixed by the bearing body 12a, but when the coins are conveyed, the pulley 5, the pulley 6, and the driven pulley 14 each independently perform a swinging motion. The coins are pressed against the transfer passage 11 and stably transferred. For example, the driven pulley 14 is the substrate 16
Attached to a pulley support plate 20 having a shaft 19 supported by a support plate 17 fixed to and a press roller support plate 18 as a fulcrum,
It swings vertically and is urged downward by a spring (not shown).

The transport passage 11 has window holes 22 (22a to 22) corresponding to the denominations of coins.
f) and protruding coin rail 23 are provided, and window holes 22a to 22f
Between the outer side of the coin and the outer surface of the coin rail 23, that is, the window hole dimensions 21a to 21f are the outer dimensions of each coin (¥ 1, ¥ 50, ¥ 5,
(¥ 100, ¥ 10, ¥ 500) and is smaller than the outer diameter of coins that are one rank larger than the outer diameter of the coins they own. Then, the window hole size is set to be gradually increased.

For this reason, the coins M conveyed as shown in FIG. 4 fall through the corresponding window holes 22. At this time, the pressing roller 41 is used to surely drop the coin M in the corresponding window hole 22. Since the pressing roller 41 is axially supported by the shaft 43 supported by the pressing roller support plate 18 fixed to the substrate 16, each pressing roller can independently swing as indicated by the arrow. Belt 15 in standby position with no coins under the presser roller
The belt 15 is hung so that the dimension g (not shown) between the lower surface on the coin transport side and the upper surface of the transport passage 11 becomes smaller than the coin plate thickness, and the stopper 44 is secured so as to secure such dimension g.
Is set by. In addition, the compression spring 45 is used to press the coin appropriately.

In this way, coins fall from the corresponding window holes 22 in the order of the smallest coin outer diameter, are counted by the sensor 32 provided on the chute 31, and fall into the collection box 33 to sort, count, and store the denominations. Is possible.

[Problems to be Solved by the Invention] A problem in such a conventional coin processing machine is to maintain the sorting performance in the coin sorting portion, particularly in the window hole portion, that is, prevent erroneous sorting.

For example, the standard outer diameter for ¥ 5 is 22 mm and the standard outer diameter for ¥ 100 is 2
It is 2.6 mm. The minimum value of the window hole size of the distribution part is set to about 22.1mm considering the dispersion of the outer diameter of ¥ 5.
On the other hand, the outer diameter of ¥ 100 is 22.6 mm and the minimum variation is about 22.4 mm, which is the maximum window hole size of ¥ 5. Therefore, the window hole size corresponding to ¥ 5, 22.1mm and 2
There is only a 0.3 mm diameter difference between it and 2.4 mm. This window hole
5 drops and ¥ 100 must be passed and transported to the next window hole. Here, if ¥ 5 is conveyed a little more than 0.3 mm or more away from the coin rail 23 that forms the dimension 21c of the window hole, ¥ 5 will not drop at the specified window hole and different denominations ¥ 100 It will fall in the window hole of and will be misclassified and miscounted.

Conventionally, in order to prevent such erroneous sorting, as disclosed in, for example, Japanese Patent Application Laid-Open No. 59-135586, a frustum-shaped pressing roller (taper roller) is provided on each window hole so that the conveyor belt is constantly operated. It is known that the pressing is performed and the conveyor belt is tilted by the pressing so that coins are conveyed while being pressed against the coin rail side. However, this is achieved by simply providing a truncated cone-shaped pressing roller. Since the pressing by the two interferes with each other and the conveyor belt does not incline at the position of the corresponding window hole, in order to prevent this, an auxiliary pulley is provided between the pressing rollers to regulate the position of the conveyor belt. However, there is a problem that the configuration becomes complicated.

In view of the above-mentioned point, the present invention makes the position of the conveyor belt between the pressing rollers by allowing the corresponding pressing roller to press and incline the conveyor belt only when the coin passes over the window hole. An object of the present invention is to provide a sorting device for a coin processing machine that does not require regulation.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention provides a substrate having a transport passage for transporting coins sent from a hopper, the substrate having an upper surface forming a transport passage surface that abuts a lower surface of the coin, and a protrusion provided on the substrate. A coin rail having one side surface that forms a conveying passage surface that abuts the outer peripheral surface of the coin, and the dimension from one side surface of the coin rail corresponds to the outer diameter of the coin to be distributed, and in the ascending order, A hopper provided with a denomination-type window hole opened in the substrate and a conveyor belt stretched in parallel with one side surface of the coin rail with an interval narrower than the thickness of the coin with respect to the upper surface of the substrate. In a sorting device of a coin processing machine, in which coins of a plurality of denominations, which are sent out one by one from the conveyor belt, are transported by the transport belt and sorted by denomination by the window hole, the transport belt is sandwiched between the windows. Denomination above the hole A frustum-shaped pressing roller having a small diameter on the side of the coin rail, a shaft that supports the pressing roller so as to be vertically swingable, and the pressing roller when the coin passes below the pressing roller. A spring for urging the shaft downward so as to press the conveyor belt, and a downward spring for the shaft so that the pressing roller does not press the conveyor belt when the coin does not pass under the pressing roller. It is characterized in that it is provided with a stopper for limiting swinging.

[Action]

In this invention, since the conveyor belt is provided on the upper surface of the substrate with an interval narrower than the thickness of coins, when the coins are conveyed, the conveyor belt is pushed up by the coins to be conveyed, and the coins are pressed by the pressing roller. When it reaches below, the pressing roller is also pushed up via the conveyor belt.

Therefore, as a reaction thereof, the conveyor belt is pressed by the pressing roller. Since the pressing roller has a truncated cone shape with the coin rail side having a small diameter, the conveyor belt is pushed toward the coin rail side and the coin rail Incline to the side.

Therefore, the coin is conveyed in this inclined direction, and is conveyed while being pushed toward the coin rail side every time it reaches the window hole, so that the coin falls from the window hole corresponding to its outer diameter.

Moreover, the stopper is provided so that the conveyor belt is tilted as described above only when the coins pass therethrough. In between, the conveyor belt is tilted at the position of each window hole without specially installing a pulley or the like to regulate the position of the conveyor belt to eliminate mutual interference, and the outer diameter corresponding to each window hole Can reliably drop coins.

〔Example〕

FIG. 1 is a plan view of the embodiment, and FIG. 2 is a sectional view taken along line II-II of FIG.

In the drawings, the same reference numerals as those in the conventional example have approximately the same function. That is, the coin M is guided from the hopper 1 having the disc 2 and the gap regulating portion 3 to the slanted surface 91 of the guide 9 by the belt 7 and the rubber roller 8 hung on the pulleys 5 and 6 on the coin transporting path 4 and transported to the transporting path 11. To be done. In the transfer passage 11, a coin rail 23 protruding above one surface and a dimension 21 (21a from the outer side surface of the rail 23 to the outer side) are provided.
~ 21f) is a plurality of window holes 22 (22a ~ corresponding to the outer diameter of each coin)
22f) is provided, and a belt 15 wound around a plurality of pulleys 13 provided on a substrate 16 and a driven pulley 14 biased downward is stretched above the window hole 22. The window holes 22 (22a-22
A sensor 3 that counts the coins falling on each of f)
A chute 31 including 2 and a collection box 33 are provided.

The characteristic structure of the embodiment is the pressing roller and the like. The pressing roller 51 that abuts the inner surface of the belt 15 stretched in parallel with the coin rail 23 has a truncated cone shape (the sloped portion of the vertical cross section has a straight line or a curved line, and the small diameter side is on the coin rail 23 side. The pressing roller 51 has its shaft 42 swinging around a fixed shaft 43 and is urged downward by a spring 45, so that the conveying passage 11 and the belt 15 maintain a dimension g (not shown) similar to the conventional one.
Equipped with. The stopper 44 causes the pressing roller 51 to press the belt 15 only when the coin M passes therethrough.

The frustoconical pressing roller 51, which is biased by the spring 45, pushes toward the coin rail 23 side at a right angle to the running direction of the belt while its slope slides on the shoulder on the inner surface of the belt 15. Therefore, due to the frictional force between the coin 15 and the belt 15, the coin M is always brought into contact with the coin rail 23 without being separated, and is conveyed on the conveying passage 11 and dropped from the correct window hole 22 corresponding to the outer diameter of the coin and distributed. Coin M
Does not leave the coin rail 23, so the coin rail 23 and the window hole
It is correctly distributed by the dimension 21 (21b to 21l) to the outside of 22.

Note that the window hole 22 corresponding to the smallest denomination (for example, 1 yen coin)
Since the coin is conveyed by the rubber roller 8 along the end of the coin rail 23, the a portion does not need to have the pressing roller because the pulley 14 plays the role of the pressing roller 51. Further, the window hole 22f corresponding to the denomination of the maximum diameter (for example, 500 yen coin) may have a size 21f which is considerably larger than the outer diameter size of the coin, so that the pressing roller is not necessary.

[Effect of device]

In this invention, a frustoconical pressing roller is provided for each denomination above the window of each denomination with the conveyor belt sandwiched between them, and the pressing roller does not press the conveyor belt during standby when a coin does not pass below the pressing roller. A stopper for restricting the downward swing of the support shaft of the presser roller is provided on the presser roller so that the corresponding presser roller presses the conveyor belt to incline it only when the coin passes over the window hole. Since it is not necessary to regulate the position of the conveyor belt to prevent the interference between the pressing rollers, erroneous sorting can be prevented with a simple configuration.
