Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a coin sorting device, and particularly to a coin sorting device that is most suitable for coin collection in an automatic pachinko ball dispensing machine.

(Conventional technology) Conventional automatic ball lending machines for pachinko play only one denomination (100
Since the use of yen coins was limited, it was sufficient to simply collect the coins inserted into the ball lending machine in one place using a collecting belt.

However, other high-value coins (for example, 500 yen coins)
yen), automatic ball lending machines for 500 yen coins in addition to the conventional 100 yen coins will be used exclusively or as dual-purpose machines, but these machines will be transported by the same collection belt. If this is done, it will be necessary to classify the coins by denomination type before collecting them into the gold box.

Traditionally, devices for sorting coins of different denominations as described above have generally adopted methods such as classification based on the shape of the coins and classification based on the material. Most of them have screening holes that match the diameter.

(Problem to be solved by the invention) However, in the above-mentioned sorting using sorting holes, holes of a size commensurate with the coin diameter are drilled in the lower wall of the passage where the coins roll in order from small diameter to large diameter. When the coins are rolled, the small-diameter coins first fall through the small-diameter hole, and then the large-diameter coins pass through the small-diameter hole and then fall through the large-diameter hole, thereby forming small-diameter coins. It was designed to separate large-diameter coins from large-diameter coins, but if the rolling speed of the coins is fast, it is easy for small-diameter coins to pass through the small-diameter holes without falling through. When trying to sort the coins at high speed, there is a problem in that the small diameter coins do not fall through the small diameter hole but fall through the large diameter hole, and the small diameter coins get mixed in with the large diameter coins, resulting in a significant drop in sorting accuracy.

In view of this, the present invention has been made with the object of providing a coin sorting device that can perform reliable sorting processing without reducing the sorting accuracy even when performing high-speed sorting.

[Structure of the idea]

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a roller near the end of the coin collection belt that eliminates the overlapping state of coins on the coin collection belt. A coin collection port is formed in the lower part along the outer circumferential surface of the pulley, and a coin classification section is provided at the bottom of the coin collection port, and the coin classification section is a coin entrance into which coins fall in a vertical position from the collection port. It is vertical in the vicinity and gradually curves into a gentle downward arc as it goes downwards, and coin holding edges having an opening width smaller than the diameter of the large coin and larger than the diameter of the small coin are formed on both sides of the edge, and the space between the holding edges is downward. a large-diameter coin passage gutter that is open, and a large-diameter coin outlet directly below the coin inlet that receives small-diameter coins that fall downward from between the coin holding edges of the large-diameter coin passage gutter; The passage gutter is characterized by having a large-diameter coin outlet at its end for receiving large-diameter coins to be ejected therefrom.

(Function) According to the present invention, the coins that have fallen onto the coin collection belt are removed from being double stacked by the rollers, and the coins are passed from the coin collection port along the outer peripheral surface of the pulley provided at the end of the coin collection belt. The coins fall vertically into the coin inlet provided at the bottom of the collection port, but small-diameter coins immediately fall between the coin holding edges of the large-diameter coin passage gutter that opens downward, and large-diameter coins fall into the large-diameter coin passage gutter. Since the edge of the coin is held by the coin holding edge and falls to the large-diameter coin outlet, coins of different diameters are not mixed, and the coins can be sorted reliably.

(Embodiments) The present invention will be described below with reference to embodiments shown in the drawings.

Figure 1 shows an embodiment in which the present invention is applied to the coin collecting section of an automatic pachinko ball lending machine, which is installed at an appropriate interval between pachinko machines. A coin collection belt 2 is installed horizontally on the back of the coin collection belt 2, and a coin collection port 4 is opened at the lower part along the outer peripheral surface of the pulley 3 at the end of the collection belt 2, as shown in the second figure. is,
A coin sorting section 5 is provided at the bottom thereof.

In the figure, 6 is a rubber reversing roller that eliminates the overlapping state of the coins C, C, etc. carried on the collection belt 2 and corrects them to a single line state, and 7 is a rubber reversing roller on the inner circumferential surface of the pulley 3. Pinch rollers are provided opposite to each other and bring the belt 2 into contact with the pulley 3 to remove slack on the upper running side of the collection belt 2. This way of installing the pinch roller 7 makes it possible to apply tension to the upper running side of the collection belt 2 without increasing the tensile force of the tension spring 9 suspended on the pulley 8 at the other end of the collection belt 2. The slack is now concentrated on the driving side.

Next, a configuration example of the coin sorting section 5 will be explained.

As shown in FIG. 2 as a longitudinal front view, a large-diameter coin passage gutter 11 is provided following the coin inlet 10 connected to the collection port 4.

This large-diameter coin passage gutter 11 includes an upper wall 12, side walls 13, 13 provided on both sides of the upper wall 12 at right angles thereto, and coins protruding inward at the tips of these side walls 13, 13. It has holding edges 14, 14, and has a substantially C-shaped cross section, and has a substantially vertical shape at the coin entrance 10 connected to the collection port 4, and gradually becomes closer to the coin holding edge 1 as it goes downward.
The opening between the coin holding edges 14 and 14 is curved into a gentle arc shape while facing downward, and then the opening between the coin holding edges 14 and 14 is curved into a circular arc shape in the opposite direction while remaining facing downward. Large diameter coin C ₁
It has a sufficient inclination for the coin to run, and its end is connected to the large-diameter coin outlet 15. In this end portion, the upper wall 12 is bent upward to create a wide space 16 so that the large-diameter coin C ₁ can easily enter the large-diameter coin outlet 15 .

Directly below the coin inlet 10 are provided funnel-shaped side walls 17 and 18, the lower ends of which serve as a small-diameter coin outlet 19. The upper part of the one side wall 18 constitutes a bottom wall 20 that extends in the lower half of the large diameter coin passage gutter 11 with a slight gap,
Furthermore, this bottom wall 20 is connected to the inner side wall of the large-diameter coin outlet 15.

The inner dimension between the side walls 13, 13 of the large-diameter coin passage gutter 11 is about 0.3 to 0.4 m/m wider than the outer diameter of the large-diameter coin _C1 to be processed, and the width of the coin holding edges 14, The dimension between the opposing surfaces is about 0.3 to 0.4 m/m wider than the outer diameter of the small diameter coin _C2 .

The large diameter coin outlet 15 and the small diameter coin outlet 19
There is a coin detection device 2 using a photoelectric element in the middle of each
1, 22 are provided, and these outlets 15, 1
The number of coins taken out from 9 is counted.

In addition, in this embodiment, the coin sorting section 5
In Fig. 2, it is divided into two parts in the direction parallel to the plane of the paper and molded with synthetic resin, and the side walls 5a, 5a
By forming a groove in the groove, the large-diameter coin passage gutter 11 is formed when the two pieces are combined. However, this large diameter coin passage gutter 11
may be incorporated as a separate structure as shown in FIG. In the figure, 23 is a gold box for collection.

Next, the operation of the above embodiment will be explained.

Small diameter coins ejected from each automatic ball lending machine 1, 1...
C ₂ and large diameter coin C ₁ fall onto the collection belt 2,
It is carried to the end by the movement of the belt 2. At this time, the double sheet is removed by the reversing roller 6, and the sheet falls vertically into the collection port 4 along the outer peripheral surface of the pulley 3 at the folded portion of the collection belt 2.

If the coin that falls into the collection port 4 is a small-diameter coin _C2 , its outer diameter is smaller than the gap between the coin holding edges 14, 14, so it immediately falls between the funnel-shaped side walls 17, 18 directly below. The coins are then collected from the small-diameter coin outlet 19 in the lower part into the coin box 23 or the like. During this time, the number of coins collected by the coin detection device 22 is counted.

When the coin dropped into the collection port 4 is a large-diameter coin C ₁ , both ends of the coin C ₁ are caught on the coin holding edges 14 , 14 which are oriented sideways and open slightly downward, so that the coin C ₁ Both ends of the coin holding edges 14, 14
The coins slide downward along the slope of the large-diameter coin passage gutter 11 while riding on the large-diameter coin passage gutter 11, reach the lower end, and are collected from the large-diameter coin outlet 15 into the coin box 23 or the like.
During this time, the number of coins collected by the coin detection device 21 is counted.

In addition, in the illustrated example, a small diameter coin (100 yen) is used.
Although we have explained the method for classifying denominations assuming large-diameter coins (500 yen), this method can also be applied to coins of other denominations as long as they have different outer diameters. Of course, in addition to the two denominations, the coin holding edges 14, 14 are installed in two stages, one for large-diameter coins and one for medium-diameter coins, and the small-diameter coins are placed directly under the collection port 4 as in the previous embodiment. Furthermore, if medium-diameter coins are collected in the middle and large-diameter coins are collected at the end, even if there are three denominations, they can be classified by outer diameter, and there is no restriction on the number of denominations.

[Effect of idea]

In this way, the present invention uses rollers to eliminate the overlapping state of coins on the coin collection belt, and allows the coins to fall vertically from the coin collection port to the coin entrance along the outer peripheral surface of the pulley provided at the end of the coin collection belt. ,
The edges of large-diameter coins are held and slid by the left and right coin holding edges of the large-diameter coin passage gutter that opens downward, and the small-diameter coins are immediately dropped from between the coin holding edges of the large-diameter coin passage gutter that opens downward. Because of this structure, there is no chance that coins that should fall will pass through the sorting hole without falling when coins are sent in at high speed, unlike with conventional sorting holes, and large-diameter coins will not meander. Moreover, since the coin is held between the coin holding edges and slides, there is no extra friction between the wall of the coin passage and the coin, and therefore the falling speed is fast and the coin does not hit the passage. Therefore, the accuracy of coin classification can be dramatically improved. In addition, there is no need to transport the coins for sorting, and the coins can be sorted using their own weight, so there is no need for any special drive device, making it extremely easy to assemble and maintain during installation. Moreover, since the coin sorting device can be easily obtained by molding synthetic resin, it can be extremely lightweight and inexpensive, and it has various effects such as there is no risk of failure.
