Abstract

PURPOSE:To reduce the load applied to a 2nd conveyor belt and at the same time to prevent the working defects of the belt due to jamming of coins by using the 1st and 2nd conveyor belts to a conveyor device together with a coin sensor. CONSTITUTION:A conveyor device M consists of a horizontal (1st) conveyor belt 30 and a tilted (2nd) conveyor belt 31, etc., and also contains a coin sensor 34. Thus the belt 30 is driven intermittently, for example, to the belt 31 and at a low speed. As a result, the coins put on the belt 30 are sent by a fixed amount to the joint area between both belts 30 and 31 so that the excessive supply of coins is avoided to the joint area. In case an excessive amount of coins are collected at the joint area, the sensor 34 set at the joint area detects this fact. Thus the drive of the belt 30 is stopped. Thus it is possible to reduce the load applied to the belt 31 and also to prevent the working defects of the belt 31 due to jamming of coins.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a coin packaging machine that collects and packages coins of the same denomination.

``Prior art'' This type of coin packaging machine is
What is shown in the above publication has been known for a long time.

This coin wrapping machine has a lower hopper installed at the bottom of the machine into which coins to be processed are input from the outside, and an upper hopper installed at the top of the machine with the coins in the lower hopper placed on the top surface. It has a conveyor belt (conhair device) that continuously conveys coins, and the conveyor belt is provided with protrusions at regular intervals for locking coins and conveying them upward.

Then, Ff! is fed into the upper hopper by the conveyance belt. The coins are sent into a rotary disk, and sent out one by one to a sorting passage by the centrifugal force of the rotary disk, where they are sorted, stacked, and packaged for each set denomination.

"Problems to be Solved by the Invention" By the way, in the coin packaging machine configured as described above, since the conveyor belt attempts to continuously convey the coins in the lower hopper upwardly to the upper hopper, The load applied to the conveyor belt increases, and in the worst case, for example, a large amount of coins conveyed may become caught between the conveyor belt and the inner wall of the device, resulting in malfunction of the conveyor belt. .

This invention has been made in view of the above circumstances, and it conveys coins little by little to a rotary disk at the top of the machine, and stacks them at the connection point between a first conveyor belt and a second conveyor belt. A VJ who can do it! The load on the second conveyor belt can be reduced by keeping the amount of cargo at a constant level, and
``Means for Solving the Problem'' Aiming to provide a coin wrapping machine capable of preventing malfunction of the second conveyor belt due to coin jamming In order to achieve the above object, (1) the first invention According to the above, there are a lower hopper installed at the bottom of the machine and into which coins to be processed are thrown, and a conveyor device that places the coins in the lower hopper on the upper surface and conveys them to a rotary disk installed at the top of the machine. In the coin packaging machine, the coins put into the rotary disk by the conveyor device are sent out one by one by the centrifugal force of the rotary disk to be sorted, stacked, and packaged. , a first conveyor belt that horizontally conveys the coins thrown into the lower hopper; and a first conveyor belt provided on the front side in the moving direction of the first conveyor belt, and which carries the coins horizontally conveyed by the first conveyor belt. It is configured to include a second conveyor belt that is locked and conveys upward, and first and second drive mechanisms that drive the first conveyor belt and the second conveyor belt, respectively.

A stop mechanism is provided that stops the driving of the first drive mechanism when the coin is detected.

"Operation" (1) According to the first invention, the first conveyor belt is driven relative to the second conveyor belt, for example, intermittently or at a low speed. A fixed amount of the coins placed thereon are sent to the connection point between the first conveyor belt and the second conveyor belt, thereby preventing excessive supply of coins to the connection point.

(2) According to the second invention, when coins exceeding a certain amount are piled up at the connection point between the first conveyor belt and the second conveyor belt, the drive of the first conveyor belt is stopped. This prevents the stacked coins from being unnecessarily pressed toward the second conveyor belt by the first conveyor belt.

"Embodiment" Hereinafter, the configuration of a coin wrapping machine that is an embodiment of the present invention will be described with reference to FIGS. 1 to 3 of the drawings.

These figures are a front view and a left side view showing a mechanism for sorting, counting, and packaging coins (coin packaging process), and a mechanism for counting coins and bagging them (bag counting process). , showing a plan view.

First, a schematic configuration for performing the former coin wrapping process will be explained along with its operation.

Reference numerals 2 and 3 in the figure indicate an upper hopper and a lower hopper, which are provided at the upper and lower parts of the machine body L, respectively, and store coins inserted from the workers 2A and 3A. The coins are transferred to a rotary disk 4 by a conveyor device M.
(These upper hoppers, lower hoppers, and conveyor devices will be explained in detail later).

The rotary disk 4 rotates in a horizontal plane around a vertical rotation axis, applies centrifugal force to the coins stored in the rotary disk 4, and directs the coins toward the sorting section 5 to sort them into I-4''. The sorting section 5 sends out the coins ejected from the coin rotary disk 4 through conveyor belts 6A and 7 disposed above.
The primary sorting passage 6 and the secondary sorting passage 7 are slid by contacting A, and these sorting passages 6 and 7 are equipped with sensors (line sensors, magnetic sensor, etc.), a large-diameter coin removal section 8 that removes large-diameter coins, a small-diameter coin removal section 9 that removes small-diameter coins, and a different denomination detection sensor/stopper for removing redundant denominations (both shown in the diagram). ) are provided sequentially along the direction of movement of the coin.

Then, in the sorting section 5, as shown in FIG. 3, in the large-diameter coin removal section 8, large-diameter coins larger than the set denomination (coins other than the set denomination) are allowed to ride on the removal member 8A and are removed. After dropping into the hole 8B, the coin is fed into a sorting box 11 through a sorting unit 10. On the other hand, the coins that have passed through the large-diameter coin removal section 8 without being removed are sent to the next small-diameter coin removal section 9 after their traveling direction is changed by approximately 90 degrees.

In this small-diameter coin removal section 9, small-diameter coins smaller than the set denomination (coins of other than the set denomination) are dropped into the small-diameter removal hole 9B between the sorting rails 9A and 9A, and then the coins are passed through the sorting chute 12 into the sorting box 11. send to.

Then, the coins (set denomination coins) that have not been removed in the large-diameter removal holes 8B and small-diameter removal holes 9B of the large-diameter coin removal part 8 and the small-diameter coin removal part 9 (set denomination coins) are further removed from the small-diameter coin removal part 9. It is fed into the front stacking section 13 and stacked in a bar shape.

In addition, if a different denomination (counterfeit coin, foreign coin, etc.) with the same outer diameter as the set denomination passes through the small-diameter coin removal hole 9■3 without being removed, the downstream of the small-diameter coin removal hole 9B The different denomination detection sensor located on the side detects this and immediately operates the stopper, and at the same time transfers the conveyor belts 6A and 7A.
This prevents the coins of different denominations from falling into the stacking section 13. Furthermore,
After the movement of the different denomination coins is stopped by the stopper, the conveyor belt 7A is reversed to widen the width of the marking sorting rails 9A, 9A, and the coins of each denomination are transferred to the small diameter removal hole 9B. , through the sorting unit 12 to the different denomination box 14 adjacent to the sorting box +1. In addition,
When discharging coins of different denominations from the sorting chute 12 to the different denomination box I4, a sorting gate 15 rotatably provided at the bottom of the sorting chute 12 about a shaft 15A is connected to When the coin is received, the coin is rotated counterclockwise A from the standby position shown in FIG.

In addition, when sorting normal coins sent through the sorting chutes 10 and 12 and not of different denominations to the sorting box II on the other side, when the normal coins are received in the receiving IJ, the marking sorting gate 15 is opened. Rotate clockwise B from the standby position shown in FIG.

On the other hand, the set denomination coins that have passed through the large-diameter coin removal section 8 and the small-diameter coin removal section 9 and are sent into the accumulation section 13 are stored in accumulation drums +3A and +3A whose mutual spacing is set according to the denomination. After the predetermined number of 50 sheets are stacked on the stacking drum 13A-
It is placed on a shutter (path shown) provided directly below 13A. Then, the accumulated coins placed on this shutter are transported to a support frame 1 which is provided below the shutter so as to be movable up and down.
6, after the shirt is handed over with the shirt open, the packaging section is further down! 7.

This packaging section 17 includes three packaging rollers 17A and 17A.
-17A, the stacked coins guided by the support frame 16 are positioned between the wrapping rollers 17A and 17A.
By rotating the wrapping rollers 17A and +7A and feeding the wrapping paper between the wrapping rollers 17A and 17A-177\ and the accumulated coins, the wrapping paper is wound around the accumulated coins.

Roll shoe 1-18 located below the packaging section 17
, a gate mechanism G is provided to distribute the fractional coins rejected due to insufficient number in the stacking section 13 to the clear box 19, and to distribute the wrapped coins wrapped in the packaging section 17 to the roll box 20. It has become.

As shown in FIG. 1, the gate mechanism G is rotatably provided around a shaft 21A and is connected to the roll chute 18.
A first gate member 21 receives and places fractional coins or packaged coins supplied through the gate member 21, and a first gate member 21 is provided to be rotatable about a shaft 22A, so that the coins placed on the gate member 21 move in the direction of arrow C. second gate member 2 that restricts movement of
2, and when guiding the fractional coins to the clear box 19 side, only the first gate member 21 is rotated in the counterclockwise direction A from the standby position shown in FIG.゛Meanwhile, the wrapped coins are placed in a roll box 20.
When guiding to the side, move from the standby position shown in Figure 1 to the second position.
Only the gate member 22 is rotated in the counterclockwise direction A.

The wrapped coins sorted by this gate mechanism 18 are placed on a basket 24A disposed at the front end of the passage 23 via a passage 23.

Then, the wrapped coins placed on the basket 24A are lifted up by a lift mechanism 24 that raises the basket 24A, and are thrown into a roll box 20 provided at the top of the machine body 1. There is.

Incidentally, when rotating the second gate member 22 of the gate mechanism 18 in the counterclockwise direction A to send out wrapped coins to the passage 23, the basket 24A is made to stand by at the front end position of the passage 23 in advance. put.

Next, a description will be given of a configuration related to the coin bag counting process performed using the above-mentioned upper hopper 2, lower hopper 3, and conveyor device M1 sorting section 5.

Between the stacking drums +3A-13A of the stacking section 13,
As shown in FIGS. 1 and 2, a guide chute 25 that rotates about a shaft 25A is provided so as to be freely inserted and removed.

When the mode is changed from the coin wrapping mode to the bag counting mode, the guide chute 25 is connected to the stacking drum 1 whose interval has been widened to the maximum in advance.
3A-13A, the set denomination coins that have passed through the sorting section 5 (coins sorted in the sorting section 5) are not stacked in the stacking section 13, and are placed between the stacking drum 13A-13A. It is designed to be excluded from the gap.

The coins removed from the accumulating section 13 are guided via a guide thread 25 to a counting chute 26 connected to the lower end of the guide thread 25. It is designed to be put into a bag that does not contain any liquids.

Next, the conveyor device M for conveying coins in the lower hopper 3 or the upper hopper 2 to the rotary disk 4 will be explained.

As shown in FIG. 2, this conveyor device M includes a horizontal belt 30 (J l conveyor belt) with a smooth surface, which is provided inside the lower hopper 3 and forms the bottom surface of the lower hopper 3; An inclined belt 31 (a second conveyor belt) is provided on the front side of the horizontal belt 30 in the moving direction, and has protrusions 31A, 31A, etc. arranged at regular intervals for locking coins conveyed by the horizontal belt 30. ) and a receiver provided below the terminal end 31B of the inclined belt 31 to receive the dropped coins after being raised by the inclined belt 31 and convey them to the rotary disk 4. A connection member 33 is provided at the connection point Z between the horizontal belt 30 and the inclined belt 31 to prevent coins passed between the belts 30 and 31 from falling to the bottom of the machine body l, and the horizontal belt 30 a first drive mechanism (not shown) that drives the inclined belt 31. The receiver is composed of a second drive mechanism (not shown) that interlocks and drives the transfer belt 32.

The end of the connecting member 33 facing the inclined belt 31 side has a comb-teeth shape with a notch formed at a portion through which the protrusions 31A of the inclined belt 31 pass.

The first drive mechanism and the second drive mechanism drive the horizontal belt 30 intermittently or at a relatively low speed with respect to the inclined belt 31, thereby causing the horizontal belt 30 to drive at a relatively low speed. At the connection point Z between the horizontal belt 30 and the inclined belt 31, as shown by the symbol m, coins are prevented from being excessively supplied and piled up beyond a certain m.

Further, within the lower hopper 3 and above the connection point Z between the horizontal belt 30 and the inclined belt 31, a coin detection sensor 34 is provided to detect that a certain number of coins are piled up. The first and second drive mechanisms are provided with a stop mechanism that stops driving only the horizontal belt 30 when the coin detection sensor 34 detects a coin.

On the other hand, the surface of the upper hopper 2 (i) facing the inclined belt 31 side is an opening 2B, and the opening 2B and the surface of the inclined belt 31 are arranged in close proximity. When a coin is inserted into the upper hopper 2 through the input port 2A, the coin is stored so as to lean against the inclined belt 31 as shown by m', and in this state, the inclined belt 311 receiver is transferred to the transfer belt. 32, the coins are scooped up by the protrusions 31A, 31A of the inclined belt 31, and thereby the coins stored in the upper hopper 2 are sequentially conveyed toward the rotary disk 4. . Note that when coins are sent from the upper hopper 2 to the rotary disk 4, it is assumed that the lower hopper 3 does not contain any coins.

On the other hand, when a coin is inputted from the input port 3A of the lower hopper 3 and placed on the horizontal belt 30, the coin is transferred to the inclined belt 31, and the coin is transferred to the protrusion 3 of the inclined belt 31.
1A, 31A, etc., and are transported toward the upper rotary disk 4.

In this case, the horizontal belt 30 is driven relative to the inclined belt 31 intermittently or at a low speed by the first drive mechanism and the second drive mechanism. Therefore, the coins can be sent one by one to the connection point Z where the horizontal belt 30 connects to the inclined belt 31, thereby preventing more than a certain amount of coins from being piled up at the connection point Z. And as a result,
The coins can be caught and lifted little by little on the protrusions 31A, 31A, etc. of the inclined belt 31, thereby reducing the burden on the inclined belt 31, and preventing the inclined belt 31 from becoming inoperable due to coin jamming. This has the effect of preventing such situations.

Furthermore, if the horizontal belt 30 and the inclined conveyance belt 31
If more than a certain amount of coins are piled up at the connection point Z, the coin detection sensor 34 detects this and turns on.
Since the stop mechanism causes the drive of the horizontal belt 30 to be stopped with respect to the first drive groove, there is no possibility that coins piled up at the connection point Z will be unnecessarily pushed toward the inclined belt 31 by the horizontal belt 30. In this respect as well, the load on the inclined belt 31 can be kept low.

Incidentally, when the coins put into the lower hopper 3 are sent to the upper rotary disk 4 by the conveyor device M, it is assumed that there are no coins in the upper hopper 2.

"Effects of the Invention" (1) According to the first invention, the first conveyor belt is driven relative to the second conveyor belt, for example, intermittently.
In addition, by driving at a low speed, the coins can be sent in fixed amounts at a time to the connection point between the first conveyor belt and the second conveyor belt. It can be locked and fried. As a result, it is possible to reduce the load on the second conveyor belt, and to prevent the second conveyor belt from becoming inoperable due to a coin jam.

(2) According to the second invention, when more than a certain amount of coins are piled up at the connection point between the first conveyor belt and the second conveyor belt, the drive of the first conveyor belt is stopped. This prevents the stacked coins from being unnecessarily pressed toward the second conveyor belt by the first conveyor belt, and in this respect as well, the load on the second conveyor belt is kept low. It has the effect of being able to
