Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a coin ejecting device for ejecting coins as change from, for example, a cash register.

[Summary of the idea]

The present invention provides a coin ejection rod that rotates around the center of the arrangement circle of the coin storage tubes below a plurality of coin storage tubes arranged in a circular manner, and this coin ejection rod stores the coins to be ejected. When it comes to the front of the coin storage cylinder, the coin ejection rod is raised and the coin ejection part rising vertically from the coin ejection rod enters the coin storage cylinder from the coin ejection rod entrance on one side thereof. The coins in the coin storage cylinder are ejected by the coin extrusion section.

[Conventional technology]

Recently, some cash registers, for example, are equipped with a coin ejecting device that automatically ejects coins as change. This type of coin ejecting device generally has coins of 100 yen, 50 yen, and 10 yen.
A plurality of coin accommodating cylinders each accommodating stacks of yen, 5 yen, and 1 yen coins in a stacked state; Some conventional coin ejection devices are equipped with a coin ejecting rod that pushes out and ejects coins that are stored in the device. A coin accommodating cylinder B is erected on the top, and a coin receiving part D is provided below the coin outlet C provided on the board A so as to be spaced apart from and facing the coin outlet C. The coin a on the coin receiving part D is pushed out and ejected by a horizontal coin pushing rod E that enters the gap from the side.

[Problem that the invention attempts to solve]

However, in the coin ejecting device having the above-mentioned coin accommodating section, the coin ejecting rod E entering the gap between the coin outlet C and the coin receiving section D is caused to vibrate vertically due to movement, and the coin receiving section D If the coin ejecting rod E were to be displaced even slightly downward just before entering the upper position, the coin ejecting rod E would abut against the coin receiving portion D and become stuck, as shown in FIG. 2. In other words, in a coin ejecting device having a coin storage section as described above,
It is necessary to make the thickness of the coin ejecting rod E less than the thickness of the coin a, and to allow the coin ejecting rod E to enter the coin receiving part D so as not to hit the coin above the coin being ejected. Therefore, if the thickness of the coin a is thin, the coin ejecting rod E should of course be made thin, and the coin ejecting rod E should be placed on the coin receiving portion D so that it is almost in contact with the top surface of the coin receiving portion D. must be entered. Therefore, if the coin ejecting rod E tries to enter the coin receiving part D with even a slight downward displacement, the coin ejecting rod E will hit the side of the coin receiving part D and become stuck, making it impossible to eject coins. Not only that, but it also deforms the coin ejecting rod E and overloads its drive mechanism, causing it to malfunction.

Moreover, since the conventional coin ejecting device uses a coin ejecting rod E that moves linearly forward and backward, a dedicated coin ejecting rod E and its drive mechanism must be provided for each coin storage section. However, the number of parts required is enormous and the price is very high.

In general, coin ejecting devices eject coins one by one from each coin accommodating section, and also eject multiple coins at once from a specific coin accommodating section, so that several coins can be ejected for a short period of time. However, in order to eject multiple coins at once from one coin storage section in the conventional device described above, it is necessary to eject the coins at once as shown in Figure 3. It is necessary to use a coin ejecting rod E having a thickness corresponding to the thickness of a plurality of coins a (for example, three), and in that case, the number of coins ejected from each coin storage section must be Since it is necessary to manufacture a plurality of types of coin extrusion rods with different thicknesses, the cost will further increase.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to prevent the coin ejecting rod from hitting the coin receptacle even if it is displaced up and down due to vibrations caused by movement. This allows coins to be ejected reliably regardless of vertical vibrations of the coin ejecting rod, and also prevents malfunctions due to deformation of the coin ejecting rod or overload of the coin ejecting rod drive mechanism. Regardless of the number of coins ejected from the coin storage tubes, coins can be ejected from all coin storage tubes using a common coin ejection rod, and the coin ejection rod and its drive mechanism are unified, reducing the number of parts and price. An object of the present invention is to provide a coin ejecting device that can greatly reduce the amount of money.

[Means for solving problems]

The present invention includes a coin ejecting rod that is rotatable and movable up and down and provided below a substrate on which a coin storage cylinder is erected; a plurality of coin storage tubes arranged on the same circumference centered around the rotation center of the coin ejecting rod; an ejecting rod rotation mechanism that rotates the coin ejecting rod; and an ejecting rod vertical movement that moves the coin ejecting rod up and down. a timing signal generating means for generating a timing signal every time the coin ejecting rod rotates by a predetermined angle as the coin ejecting rod rotates; and a timing signal generating means for detecting the position of the coin ejecting rod based on the timing signal; When the coin ejecting rod comes in front of the coin storage cylinder containing the coin to be ejected, the ejecting rod vertical movement mechanism is operated to raise the coin ejecting rod to the coin ejecting height, and the coin ejecting rod is raised to the coin ejecting height. and a coin ejecting control means for lowering the coin ejecting rod by reversely operating the ejecting rod vertical movement mechanism after the coin has passed through the coin storage cylinder, and the coin ejecting rod is in a lowered state when the coin ejecting rod is in a lowered state. A coin ejecting part is vertically provided and positioned below the lower end of the coin accommodating cylinder and whose upper end protrudes above the lower end of the coin accommodating cylinder when the coin ejecting rod is lifted. Each of the coin storage cylinders has a coin receiving part at the lower end thereof for receiving coins stored in a stacked state in the coin storage cylinder, and coin ejecting rod entry ports into which the coin ejecting part of the coin ejecting rod enters on both sides of the lower end. and a coin ejecting port are provided in the coin receptacle, and the coin ejecting rod inlet and the coin ejecting port are communicated with each other so that the coin ejecting portion of the coin ejecting rod is connected from the coin ejecting rod inlet to the coin ejecting port. It is characterized by having a structure in which a coin extrusion rod passage groove is provided.

[Effect]

That is, the present invention raises the coin ejecting rod rotating through the bottom of each coin storage tube when it comes in front of the coin storage tube containing the coin to be ejected. The coins in the coin storage cylinder are ejected by the coin ejecting part provided on the coin ejecting rod, and the coin ejecting part provided vertically up from the coin ejecting rod is The coin enters into the coin storage cylinder from the coin ejection lever entrance on one side of the coin storage cylinder, passes through the coin ejection rod passage groove formed in the coin receiving part at the bottom end of the coin storage cylinder, and pushes out the coin. The coins exit from the coin ejection port opened on the other side. Therefore, according to the present invention, even if the coin ejecting rod is displaced up and down due to vibrations caused by movement, the coin ejecting portion of the coin ejecting rod can enter the coin storage tube without hitting the coin receiving portion of the coin storage tube. Therefore, coins can be ejected reliably regardless of the vertical vibration of the coin ejecting rod, and since the coin ejecting rod does not hit the coin receiving part of the coin storage cylinder, the coin ejecting rod can be ejected reliably. It is possible to prevent failures due to deformation or overload of the coin ejecting rod drive mechanism. Moreover, in the present invention, since the coin ejecting part of the coin ejecting rod is provided vertically, it is possible to eject coins with a common coin ejecting rod regardless of the number of coins ejected from each coin storage cylinder. It is also possible to rotate the coin ejecting rod so that its coin ejecting part passes under a plurality of coin storage tubes arranged on the same circumference, and to move the coin ejection rod in front of the coin storage tube containing the coins to be ejected. When the coin ejecting rod comes, the coin ejecting rod is raised to the coin ejecting height and the coins are ejected from the coin storage tubes, so that the coins are not ejected from all the coin storage tubes. Since this can be done using a common coin ejecting rod, the coin ejecting rod and its driving mechanism can be unified, and the number of parts and cost can be greatly reduced.

The timing pulse from the timing signal generating section 40 which generates a timing pulse every time the extrusion rod comes to the front position) is counted, and the count value of this counter 42 is sent to the extrusion rod position determination circuit 42. . In addition, the timer 44
is started when a timing pulse is given from the timing signal generator 40 (when the coin ejecting portion 18a of the coin ejecting rod 18 comes in front of the coin storage tubes ₉₁ to ₉₅ ), and the coin ejecting rod 18 is activated. Extrusion part 1
When the time required for the coin storage tubes 9 ₁ to 9 _{5 to pass through the coin storage tubes 9 1 to 9 5} is measured, the push rod position determination circuit 42
This timer 44 sends a push rod passing signal to

It is determined that the coin ejecting portion 18a of the coin ejecting rod 18 has passed the first coin storage tube ₉₁ when the ejecting rod passing signal is inputted from the timer 44 _. Similarly, each time the count value of the counter 43 becomes "2", "3", "4", or "5", the coin ejecting portion 18a of the coin ejecting rod 18 moves to the second, third, fourth, or fifth position. Coin storage cylinder 9 ₂ , 9

Note that the counter 43 determines when the coin extrusion portion 18a of the coin extrusion rod 18 passes the last coin storage cylinder (fifth coin storage cylinder) ₉₅ and this is determined by the extrusion rod position determination circuit 42. The counter 43 is reset to the initial state (count value "0") by a reset signal from the push-out rod position determination circuit 42, and the count value of the counter 43 is determined when the coin push-out portion 18a of the coin push-out lever 18 is When it comes before the first coin storage tube ₉₁ again and a timing pulse is input, it becomes "1".

Further, in FIG. 12, 45 is a coin discharge control section, and 46 is a discharge coin designation section. The discharged coin designating section 46 sets the type and number of coins to be discharged according to a change amount signal sent from a cash register (not shown).
If the amount is 230 yen, the ejected coins are two 100 yen coins,
Three 10 yen coins are set and held in the register, and this ejection coin signal is sent to the coin ejection control section 45. The coin ejection control section 4
5 controls the solenoid 21 for ejecting the ejecting rod based on the ejecting coin signal from the ejecting coin specifying section 46 and the ejecting rod position signal from the ejecting rod position determining circuit 42. For example, 100
When a signal for a yen coin is being sent, the coin ejecting portion 18a of the coin ejecting rod 18 is inserted into a coin storage cylinder containing a 100 yen coin (for example, the first coin storage cylinder 9).
₁ ) When the position signal is input from the ejecting rod position determination circuit 42, the solenoid 21 is excited and driven to raise the coin ejecting rod 18 to the coin ejecting height, and the coin ejecting rod 18 is pushed out. Extrusion section 18
When the coin a passes through the coin storage tube and its position signal is input from the pushing rod position determination circuit 42, the excitation of the solenoid 21 is stopped and the coin pushing rod 18 is lowered by the spring force of the return coil spring 20. At the same time, a 100 yen coin discharge completion signal is sent to the discharged coin designating section 46 to subtract 1 from the number of 100 yen coins held in the register of the discharged coin designating section 46. This also applies to the case of discharging other types of coins, and this coin discharging operation is repeated until the number of each coin held in the register of the discharged coin designating section 46 becomes zero.

(2) Operation Next, the operation of ejecting change coins by the coin ejecting device will be explained.

The rotating shaft 2 is always rotated at a constant speed by constantly driving the motor 5, and thereby the coin ejecting rod 18 held by the holding member 17 is also always rotated at a constant speed. When coins are not ejected, the coin ejecting rod 18 is moved to its coin ejecting portion 1.
8a is rotated while passing below the bottom surface of each coin storage tube ₉₁ to ₉₅ , that is, the top surface of the coin receiving section 12, and when ejecting a coin, the coin ejecting section 18a removes the coin to be ejected. When the solenoid 21 is energized when the coin storage tube comes in front of the coin storage cylinder containing the coin, the plunger rod 23 pushes up and rotates the coin. That is, for example, when trying to eject a coin stored in the coin storage cylinder ₉₃ , the coin ejection portion 18a of the coin ejection rod 18 rotated in the direction of the arrow in FIG. ₃ and the coin storage tube ₉₄ through which the coin ejecting portion 18a passed before, the coin ejecting rod 18 is pushed up and rotated, and the flange 23a of the plunger rod 23 is moved to the solenoid 21.
By hitting the case 25 of the coin ejecting unit 1
8a rises to a position where it hits only the coin to be ejected on the coin receiving section 12. However, the coin ejecting part 18 of the lever
As the coin ejecting rod 18 continues to rotate, the coin enters the coin receiving portion 12 from the coin ejecting rod entrance 10 and passes through the coin ejecting rod passage groove 13 while pushing the ejected coin. The coins that are ejected from the coin ejection port 11 and pushed out from the coin ejection port 11 fall onto the coin guide plate 30 and are ejected into a change tray (not shown). Further, after this, the coin ejecting rod 18 is rotated downward by the elastic force of the spring 20 as the solenoid 21 is brought into a non-driving state, so that the coin ejecting part 18a remains in the coin receiving part 12 until the next coin is ejected. It is rotated while passing under the top surface. In other words, in this coin ejecting device, the coin ejecting rod 18 is rotatably moved below each of the coin storage tubes 9 ₁ to 9 ₅ as described above, and the coin ejecting rod 18 is rotated when discharging coins.
8 is pushed up and rotated to project the coin ejecting part 18a above the coin receiving part 12.
The coin ejecting section 18a is designed to push out and eject the coin a received on
is a coin ejecting rod passage groove 13 provided in the coin receiving part 12
Since the portion other than the coin ejecting portion 18a passes under the coin receiving portion 12, the coin ejecting rod 18 does not come into contact with the coin receiving portion 12 and become stuck.

FIGS. 8 and 9 show the coin ejecting state from the coin receiving section 12 when the coin storage tube is for discharging one coin, and the coin is pushed up and rotated before entering the coin receiving section 12. The coin ejecting rod 18 enters from the coin ejecting rod entrance 10 with the coin ejecting portion 18a protruding above the coin receiving portion 12, and pushes out the coin a through the coin ejecting rod passage groove 13. Therefore, when ejecting coins from this coin storage tube, even if the coin ejecting rod 18 is displaced vertically due to vibrations or the like due to movement, the coin ejecting rod 18 will not hit the coin receiving portion 12, and the coins will always be ejected reliably. Can be discharged. In addition, in the above coin ejecting device, when the coin is not being ejected, as long as the coin ejecting rod 18 is lowered until the upper end of the coin ejecting portion 18a is positioned below the upper surface of the coin receiving portion 12, the coin can be removed without hitting the coin a. Since the extrusion rod 18 can be rotated, the coin receiving section 1 can be moved at maximum compared to conventional devices.
The vertical stroke of the coin ejecting rod 18 can be reduced by the thickness of the coin ejecting rod 18.
The lifting and lowering operations can be performed in a short time, and the solenoid 21 can also be made smaller. Moreover, FIG. 10 shows a coin storage cylinder used when ejecting a plurality of coins a, a at once, and as shown in FIG. 9a, and set the opening height of the coin extrusion lever entrance 10 and the coin ejection opening 11 to a height that can eject multiple coins (three in this example) (the upper edge of the opening can also be used for ejecting one coin). If the coins for discharging a plurality of coins are also aligned at the same height), a plurality of coins can be discharged at once by simply performing the above-mentioned coin discharging operation. That is, since the coin ejecting portion 18a of the coin ejecting rod 18 projects above the coin receiving portion 12 through the coin ejecting rod passage groove 13, the entire height of the portion protruding onto the coin receiving portion 12 allows the coin to be pushed out. Therefore, different numbers of coins can be ejected by the same coin ejecting rod 18.

In addition, since the coin storage cylinder has the coin storage cylinder main body 9 and the coin receiving part 12 integrated,
Even if the coin storage cylinder is removed from the base plate 1 with the coin a remaining in the storage cylinder when replenishing the coin a, the coin a in the cylinder falls from the bottom end of the storage cylinder because it is received by the coin receiving part 12. This does not happen, and therefore the coin a remains in the storage cylinder without waiting for it to become empty, unlike in conventional coin storage units in which the coin storage cylinder and the coin receiving part are separated. I can replenish my house with coins a.

(3) Other Embodiments In the above embodiments, the coin accommodating cylinder main body 9 is integral over its entire length, but the coin accommodating cylinder main body 9 may be of the following two-part type. That is, FIG. 11 shows the coin storage cylinder main body 9.
shows an example in which the lower cylinder 31 has a coin receiving part 12 and an upper cylinder fitted onto the lower cylinder 31, and the lower cylinder 31 is positioned on the side surface of the board fitting part. The upper tube 32 has a flange-like stepped portion 33 on its upper portion that is received by the upper surface of the substrate 1. The upper tube 32 has a fitting tube portion at its lower end that is fitted into the lower tube 31. 34, and a shutter plate 35 that is slidable on this fitting cylinder portion 34.
It is said that the structure is such that it is inserted through. The shutter plate 3
5 has a manual operation grip part 36 at its base end,
A coin passing hole 37 is opened in the portion near the base end, and the shutter plate 35 is
When pulled, the lower end of the upper tube 32 is closed by the surface of the shutter plate 35, and when the shutter plate 35 is pushed in, the coin passing hole 37 aligns with the lower end opening of the upper tube 32, as shown by the chain line. The upper cylinder 32 and the lower cylinder 31 are configured to communicate with each other. Also, 3
8 is a stopper provided on the base plate 1, and when the shutter plate 35 is pushed in, the tip of the shutter plate 35 enters the lower side of the stopper 38, so that the upper cylinder 32 cannot be lifted up. It is locked. Therefore, if the stopper 38 is provided, the upper cylinder 32 cannot be removed unless the lower end of the upper cylinder 32 is closed by operating the shutter plate 35, and thus the upper cylinder 32 cannot be removed without closing the shutter plate 35. It is possible to prevent operational errors such as removing the upper cylinder 32, and to replenish coins by removing the upper cylinder 32 without dropping the coins even if there are coins remaining in the upper cylinder 32. Note that the means for closing the lower end of the upper cylinder 32 when the upper cylinder 32 is removed is not limited to the one in the above embodiment. Other means may also be used, such as one that elastically enters the upper cylinder 32 to support the coin when the upper cylinder 32 is lifted.

The coin ejection device of the present invention can be used to automatically eject not only coins but also pseudo coins (tokens), etc., and the coin storage tube is not limited to the cylindrical one as in the above embodiment. The shape may be selected depending on the shape of the coin or pseudo coin to be accommodated, such as an elliptical cylinder or a rectangular cylinder.

[Effect of idea]

According to the present invention, even if the coin ejecting rod is displaced up and down due to vibration due to movement, it does not hit the coin receiving part, and coins are reliably ejected regardless of the vertical vibration of the coin ejecting rod. At the same time, it is possible to prevent malfunctions due to deformation of the coin ejecting rod or overload of the coin ejecting rod drive mechanism. Since coins can be ejected using the coin ejecting rod, the coin ejecting rod and its driving mechanism can be unified, and the number of parts and cost can be greatly reduced.
