Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a coin sorting device that is installed in a vending machine or the like and has a carrier arm for sorting inserted coins. This invention relates to means for preventing continuous coin insertion to prevent erroneous sorting due to continuous insertion of coins.

[Prior Art] A coin sorting device installed in a vending machine or the like has a structure in which coins are sorted based on the outer diameter, thickness, and material of the inserted coins, and the coins are guided into designated passages. ing.

FIG. 1 is a front view showing a schematic configuration of such a coin sorting device, in which 1 is a coin sorting device, 2 is a substrate,
3 is a coin slot, 4 is a cradle as a coin sorting member, 5 is a coin rail, 6 is a magnet, 7 is a deflector, 8 is a separator, and 9 is a carrier arm as a coin sorting member.

Coins inserted through the coin input port 3, coins whose outer diameter is smaller than the dimension between the protrusions 41 and 42 of the cradle 4, enter the window 21 opened in the base plate 2 as shown by the trajectory abc.
are guided to a coin passage (not shown) provided on the back side.

Further, coins with a larger outer diameter than between the protrusions 41 and 42 are guided onto the coin rail 5 by the cradle 4, and sorted by the following materials by the magnet 6, deflector 7, and separator 8. .

When a coin passes through the magnetic field of the magnet 6 installed at the end of the coin rail 5, the degree of braking force received differs depending on the material, so coins that are strongly braked will slide down as shown in the trajectory de, or , the coin that has not received much braking falls onto the deflector 7, and due to the difference in repulsive force, the coin has a trajectory dfe or a trajectory dfg.
It's played like this. Then, the coins that have jumped over the separator 8 are subjected to a second outer diameter sorting by the carrier arm 9, and those having a predetermined outer diameter are guided to the coin passage 10 along a trajectory fgh. still,
101 is a side wall that partitions the coin passage 10.

Next, the manner in which the outer diameter is sorted by this carrier arm 9 will be described in detail based on the operational diagram shown in FIG. The carrier arm 9 consists of two parts, an arm part 91 and a weight part 92, and the shaft 1 is arranged so that a protrusion 911 provided at the tip of the arm part 91 projects into the coin passage.
1, and in a standby state, the protrusion 911 abuts an upper stopper (not shown) provided on the wall of the coin passage, and the arm part 91 stands still with the arm part 91 substantially horizontal as shown by the solid line. . When the carrier arm 9 rotates clockwise around the shaft 11 to the position shown by the broken line (hereinafter referred to as bottom dead center), it comes into contact with a lower stopper (not shown) and is prevented from rotating. Here, the distance A between the protrusion 911 in the standby state and the side surface 12 of the coin passage, and the distance B between the protrusion 911 and the side surface 13 at the bottom dead center are set so that A<B, so that the separator 8 A coin that has jumped over the gap and has an outer diameter larger than the interval A and smaller than the interval B is caught between the protrusion 911 and the side surface 12, and the coin's own weight causes the carrier arm 9 to move clockwise as shown by the broken line. When the coin rotates to the bottom dead center, the distance from the side surface increases, so the coin passes between the protrusion 911 and the side surface 13 and is guided into the coin path 10 along the trajectory gh. In addition, for coins whose outer diameter is smaller than the interval A, the protrusion 911 and the side surface 12
Because it passes through (interval A), the trajectory gi
slide down like.

However, after the carrier arm 9 has guided the coin to the coin passage 10, if the next coin jumps over the separator 8 while returning to the standby position due to the weight of the weight section 92,
The coin may collide with the protrusion 911 of the rotating arm portion 91 and be introduced into the coin passage 10 even though the coin has a small diameter. In order to prevent such erroneous sorting due to continuous insertion of coins, conventional means have been taken to prevent repeated insertion of coins into the rolling path.

FIGS. 3 and 4 show repeat-throw prevention means used in a conventional coin sorting device. Figure 3A,
The repeat-throw prevention means 14 shown in B is rotatably mounted above the carrier arm 9, and in the standby state is kept balanced at the position shown by the solid line by a weight 142. Then, the coin that is repelled by the deflector 7 and jumps over the separator 8 collides with a protrusion 143 that projects into the rolling path from a notch 151 provided in the path wall 15 shown in Figure B, and the repeated throw prevention means 14 is blocked. Rotate the carrier arm 9 clockwise.
slide upwards. A protrusion 144 provided at the other end of this repeated throwing prevention means 14 is connected to the deflector 7 as shown by a broken line.
The second coin that is thrust out in the direction shown in FIG.

4A and 4B is rotatably supported by shafts 161, 161 at the entrance of the coin passage 10 below the carrier arm 9, and in the standby state is supported by a weight 162 as shown in FIG. A notch 15 in which a protrusion 163 is provided in the passage wall 15 as shown in B
1 into the coin passage 10. When the protrusion 163 protruding into the passage is pushed by the coin guided into the coin passage 10 by the carrier arm 9, the repeat-throw prevention means 16 rotates around the shafts 161, 161, and is mounted at the upper end. A protrusion 164 protrudes into the passage from the notch 152 and blocks the coin passage 10. Therefore, while the protrusion 164 projects to the entrance of the coin passage 10, the coins guided by the carrier arm 9 are prevented from sliding into the coin passage 10 (for example, as in
−164372).

[Problem that the invention attempts to solve]

The two types of repeat-throw prevention means shown above are provided above or below the carrier arm, and although the respective prevention means are different, they operate when the first coin hits the protrusion of the repeat-throw prevention means, and are activated when the first coin hits the projection of the repeat-throw prevention means. They have a common feature in that they prevent erroneous sorting due to continuous insertion by protruding a protrusion that flips coins that are subsequently inserted. Since such conventional repeat-tossing prevention means operate by directly detecting rolling coins, they are provided outside the rotational movement area of the carrier arm shown in FIG. 2 and operate independently of the carrier arm, so for example If the rear arm becomes locked during its return as shown by the broken line in Figure 4 due to the adhesion of dust, subsequent coins will collide with the protrusion of the carrier arm and jump into the coin passage, regardless of their outer diameter, resulting in false coins. Unauthorized purchases of goods using coins occur. In addition, since the above-mentioned repeated firing prevention means is installed separately at a location different from the carrier arm, it requires a relatively long rolling path for installation, and has the disadvantage that it can only be applied to a limited number of devices. Ta.

Therefore, the technical problem of the present invention is to enable the repeated pitch prevention means to operate by the rotation of the carrier arm.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention includes a coin passage between a substrate and a side wall, a coin passage rotatably supported by the side wall in a plane parallel to the side wall, and an arm portion on one end side. a carrier arm having a protrusion protruding into the coin passageway at its tip that is rotated by engaging with the rolling coin, and having a weight portion on the other end side for returning the coin to a substantially horizontal standby state; and a carrier arm on the side wall side. In the coin sorting device, the coin sorting device is equipped with a seesaw-shaped repeated throw prevention lever that is swingably attached to the side wall in a direction perpendicular to the side wall. A contact portion is provided that is curved in the direction of rotation so that the arm portion of the carrier arm that is positioned and rotated comes into contact with the arm portion of the carrier arm.
The other end is provided with a protrusion that is projected into the coin passage when the arm comes into contact with it, and a weight that biases the protrusion in a direction to move the protrusion out of the coin passage.

[Effect]

In the present invention, when the carrier arm is rotated by a rolling coin, the arm portion comes into contact with the abutting portion on one end side of the repeat-throw prevention lever, so that the protrusion on the other end side is projected into the coin path. This protrusion prevents the next coin from reaching the carrier arm and prevents missorting. and,
The contact part of the repeat-throw prevention lever is curved in the direction of rotation of the carrier arm, so while the carrier arm is rotating (until it returns to the standby state), the protrusion protrudes into the coin passage, preventing the next coin from entering. Reaching the carrier arm is prevented.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIGS. 5A and 5B are a front configuration view and a vertical sectional view showing an embodiment of the present invention. In the figure, the multiple-throw prevention lever 17 has a shaft 171 provided on its lever body that is pivotally supported by a support part (not shown to simplify the drawing) so that it can swing in a seesaw shape. A portion 172 is arranged within the rotational movement of the carrier arm 9, and the other pivoting portion 173 is provided with a projection 174. In the standby state, the swinging portion 173
Due to the rotational moment in the counterclockwise direction (in figure B) due to the weight 175 provided at When it comes into contact with the base plate 2, the protrusion 174 is in a state where it is pulled out of the coin rolling path.

When a coin is inserted into the coin input port 3 during such a standby period, the coin is first sorted by its outer diameter by the cradle 4, as explained in FIG.
coins with a predetermined outer diameter (for example, the coin sorting device 1 is capable of sorting new 500 yen coins).
If the front side of the board 2 shown in the figure sorts out 10 yen coins and 500 yen coins, and the back side sorts 50 yen coins and 500 yen coins, then 10 yen coins and 500 yen coins)
is led to coin rail 5. And magnet 6,
The materials are sorted by the deflector 7 and the separator 8, and only the coins made of a predetermined material are selected. Only the yen coins) jump over the separator 8 and reach the carrier arm 9. The operation of the carrier arm 9 was previously explained based on FIG. 2, so a detailed explanation will be omitted.
When the carrier arm 9 rotates, the repeated firing prevention lever 1
In order to push up the swinging part 172 by coming into contact with a surface (hereinafter referred to as a contact surface) 176 of the swinging part 172 of No. Then, the protrusion 174 provided on the swinging portion 173 is inserted into the notch 152.
It protrudes into the passage 10 after the coin passes through. Since the swinging portion 172 is curved in the direction of rotation of the carrier arm 9, it always comes into contact with the contact surface 176 and pushes up the swinging portion 172 during rotation, and the protrusion 174 allows the carrier arm 9 to stand by. It will continue to protrude into the passage 10 until it returns to its original position.

Therefore, even if a subsequent coin is repelled by the deflector 7 and jumps over the separator 8 during the rotation of the carrier arm 9, it will be repelled by the protrusion 174 and will be prevented from reaching the carrier arm 9, resulting in repeated coin tossing. It is possible to reliably prevent erroneous selection of the carrier arm 9 due to this. Then, as the carrier arm 9 returns, the swinging portion 172 again protrudes from the notch 151 into the rotating movement area of the carrier arm as shown in Fig. Lever 1 to prevent repeated pitching after being ejected
7 also returns to the standby state.

The swinging portion 172 of the repeated firing prevention lever 17 shown in FIG.
The lever is slightly bent in a dogleg shape so as to protrude into the passageway, and the tip is thick for strength reasons; however, the present invention is not limited to this type of repeated firing prevention lever. , it may be a simple rod-shaped swinging part.

[Effect of idea]

According to the present invention as described above, since the repeated throw prevention lever is operated by the rotation of the carrier arm, the repeated throw prevention lever is installed in the rotation area of the carrier arm, and the coins driving the lever are rolled. The moving coin passage can be shared, and the required coin passage can be shortened compared to the conventional case where the coin passage is provided at separate positions. Therefore, it is possible to make the coin sorting device more compact and to sort more denominations of coins within the same space.
