BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball counter for pachinko balls and the like.

[0002]

2. Description of the Related Art As shown in FIG. 13, a conventional ball counter 1a is provided so as to be connected to a hopper b for receiving a ball a and a ball discharge port c below the hopper b, and the balls a are aligned in a plurality of rows. The ball a gradually narrows from the base end near the ball discharge port c toward the front end with respect to the bottom plate having a predetermined angle of inclination.
, One detecting unit e for detecting each ball a passing through each row of the counting unit d, and a ball passing through the counting unit d based on a signal of the detecting unit e. On the downstream side of the ball counter 1a, various devices such as a lifter for transporting the ball a upward and a polishing device for removing dirt on the ball a are provided. is set up.

When the ball a is thrown into the hopper b of the ball counter 1a, the hopper b moves the ball a toward the ball discharge port c because the bottom plate is inclined toward the ball discharge port c. Rolling, the balls a are dropped into the counting unit d from the ball discharge port c, and the balls a are aligned in a plurality of rows by a plurality of passages configured to be separated by the side plate and the bottom plate so that the balls a pass one by one. Since these passages are inclined and gradually narrowed, the balls a arranged in a plurality of rows pass through the rolling detection unit e one by one. The detection unit e has an optical sensor composed of a light emitting unit and a light receiving unit. The ball a passes through the detection unit e and cuts off the light of the optical sensor as a pulse signal. Is added by the number of passages to count the balls a. As a result of various contrivances, the counting speed of the ball a is considerably high at present, and is, for example, about 12000 pieces / minute to 24000 pieces / minute.

[0004] Further, the counting speed of the conventional ball counter 1a constructed as described above can be easily increased by increasing the inclination of the counting unit d. However, if the inclination of the counting unit d is made steep, the ball a tends to clog in the passage.
A diaphragm h is attached to the upper surface of the passage, and the diaphragm h is
What opens and closes in the direction is known.

[0005]

However, in the above-described conventional ball counter 1a, the ball a is collected from the wide ball input port of the hopper b to the narrow ball discharge port c by using gravity.
Since the ball a is divided into a plurality of passages of the counting unit d and passed through the plurality of passages, and the ball a is counted in the process, a certain head is required. If this head is large, it is possible to increase the counting speed of the ball a. However, the ball is clogged in the ball discharge port c and the counting unit d, which requires manpower or increases the machine height to handle the ball a. As a result, the counting speed of the ball counter 1a has a certain limit.

In the ball counter 1a, the inclination of the counting unit d is relatively gentle in order to prevent clogging, and the number of balls passing through one passage per unit time is not so large. For this reason, there is no other way to increase the counting speed per ball counting machine 1a except for increasing the number of passages. The ball counting machine 1a becomes larger as a whole, and how to effectively use a small installation area. It is desirable from the point of view that the ball counting machine in which the inclination of the counting unit d is steep, and in which a diaphragm h for preventing the clogging is provided, also opens and closes the diaphragm h to prevent clogging of the balls in the passage by the vibration. Therefore, when the diaphragm h is opened, the balls a may overlap, and conversely, clogging may occur.

Further, in the conventional ball counter 1a, the counting speed is restricted by the processing speed of various devices installed on the downstream side thereof. For this reason, for example, it takes time to count the pachinko balls, and in order to cope with giving a customer a wait and giving discomfort, the ball counting machine 1 with a high counting speed is used.
Even if it is going to install a, with the renewal of this ball counting machine 1a, it is sufficient that these lifters and polishing devices have a processing speed in accordance with the counting speed. Lifters and polishing equipment must be updated at the same time, and due to installation space and cost,
In some cases, these lifters and polishing apparatuses cannot be updated.

Therefore, the present invention has been made in view of the above circumstances, and the height of the aircraft is the same as or less than the conventional one, so that no wasteful space is produced, a small installation area can be effectively utilized, and ball jamming is achieved. It is an object of the present invention to provide a ball counter capable of improving the ball counting speed with almost no occurrence.

In addition, even if the counting speed is higher than the processing speed of the various devices installed on the downstream side, the ball counting machine can be installed without updating the various devices to one adapted to the counting speed. To provide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to FIGS. 1 is a perspective view of the ball counter of the present invention, FIG.
Is a side view of a main part of the ball counter, and FIG. 3 is a perspective view of the counting unit. In the figure, reference numeral 1 denotes a ball counter. The ball counter 1 comprises a counter body 2 and a hopper 4 provided at an upper portion of the counter body 2 for receiving and temporarily retaining balls 3.
And two counting units 6, 6 that are arranged below the hopper 4 and are arranged in a plurality of rows so that the balls 3 are aligned and passed therethrough, and the balls 3 that pass through the passages 5 of these counting units 6, 6. And a display unit 8 for calculating and displaying the total quantity of the balls 3 passing through the counting units 6 based on the signals of the detecting units 7 and 7, respectively.

The counter body 2 has a rectangular parallelepiped shape, and has a display panel 9 constituting a part of the display unit 8 on the upper surface, and the other part is open and the hopper 4 is attached. A power switch 10 and a power cord (not shown) are mounted on the back of the counter body 2, and a chute (not shown) for receiving the balls 3 after counting is provided on the lower surface thereof.
A pipe or the like is connected to the chute to transfer the ball 3 to a predetermined place.

The hopper 4 has a quadrangular pyramid shape, the side plate 4a # has a gentle slope, the bottom is open to form a ball discharge port 11, and the received balls 3 are collected in the ball discharge port 11. Let it fall. The capacity of the hopper 4 is set, for example, to be equal to or larger than the maximum capacity of 1 mm in which the ball 3 put out by the pachinko machine by the customer is placed.

The two counting units 6 include a hopper 4
Are provided on the left and right sides of a partition plate 12 located at the center of the ball discharge port 11 of FIG. Therefore, the total quantity of the passage 5 is 1
Since the number of the passages 5 in one counting unit 6 is doubled, the number of the balls 3 passing through the passage 5 is also doubled, and the counting speed per one ball counter 1 is doubled. That is,
Since the capacity of the hopper 4 is set to be equal to or larger than the maximum capacity of 1 mm for storing the balls 3, the outer dimensions (vertical dimensions) of the hopper 4 require a certain size, and the range of the outer dimensions It is possible to provide two or more counting units 6 having the same number of passages as before.
The counting unit 6 has a long side wall bar that is inclined from the base end (partition plate 12) side to the front end side and plays the role of a side wall.
13─ and a short bottom wall 14─ which plays the role of the bottom wall are alternately arranged, and the side walls 13, 13 and the bottom wall 14 form the passage 5 through which one ball 3 can just pass one after another. Do it. The height of the passage 5 gradually decreases from the base end to the distal end, and has a height such that only one ball 3 can pass near the distal end outlet 15. A top plate 16 for guiding this is stretched at the tip of the upper surface of the side wall bar 13.

The detection unit 7 is provided with an optical sensor 17 having a light emitting surface 17a and a light receiving surface 17b, which is located at the front end outlet 15 for each one of the passages 5 of the counting unit 6, and has
Each time the light from the optical sensor 17 is intercepted by the ball 3 coming out, it is taken out as a pulse signal, and the transmitter 18 transmits the pulse signal to the display unit 8. This detection means is not limited to an optical sensor, but may be another means, for example, a magnetic sensor.

Then, the pulse signals transmitted from the transmitter 18 are added for each path 5 on the display unit 8, and the total number of the balls 3 is calculated by adding up the number of additions for each path 5. The total amount of the balls 3 after the calculation is immediately displayed on the display panel 9 which is a component of the display unit 8.

In FIG. 1, reference numeral 19 denotes a printer for printing out the number of balls.

Next, the operating state of the ball counter 1 having the above configuration will be described. First, the power switch 10 of the ball counter 1
Is turned on and other acceptance conditions are checked, and if there is no problem, it is ready for acceptance. Next, the balls 3 are put into the hopper 4 from a container containing the balls 3 discharged from a game machine such as a pachinko machine. The capacity of the hopper 4 is 1
Since the ball 3 has a sufficient margin more than the capacity of the ball 3, the ball 3 does not overflow from the hopper 4 and gathers at the ball discharge port 11 in the center by the gently inclined side plate 4 a,
The two counting units 6 and 6
Fall into one of the. The ball 3 that has fallen into one of the counting units 6 is regulated by the side wall bar 13─ and
Enter ─. At this time, the base end side of each passage 5 is two balls 3 deep.
The balls 3 are aligned for each passage 5 by the inclination of the bottom wall bar 14 ° and the top plate 16 that gradually narrows the height of the passage 5. The balls 3 arranged for each passage 5 are discharged one by one from the distal end outlet 15. For this reason, the light emitted from the light emitting surface 17a of the optical sensor 17 of the detection unit 7 is intercepted one by one by the ball 3 and does not reach the light receiving surface 17b, and is extracted as a pulse signal by the transmitter 18 of the detection unit 7. The pulse signal is transmitted to the display unit 8.

The display section 8 adds up the pulse signals transmitted for each passage 5 and sequentially adds up the added numbers of the passages 5 to calculate the total amount of the balls 3, and displays the result on the display panel 9. . Accordingly, since there are two counting units 6, the counting speed of the balls 3 can be increased overall without increasing the head so much, and the space generated by installing one counting unit 6 can be effectively used. Can be used.

FIG. 4 shows a ball counter 1b showing another embodiment of the present invention. The difference from the embodiment shown in FIGS. 1 to 3 is that the balls 3 are moved in the same direction with the counting unit 6 being superposed. The point is that the balls 3 are counted in a plurality of rows. Other configurations and operations are shown in FIG.
3 to FIG. 3, the reference numerals are attached to the drawings and the description is omitted.

In the above-described embodiment, the case where two counting units 6 are provided has been described. However, the present invention is not limited to this, and two or more plural units may be provided.

FIGS. 5 to 7 show a ball counter 1c showing another embodiment of the present invention. FIG. 5 is a perspective view of a ball return machine having a built-in prevention device, and FIG. 7 is a plan view of the prevention device. In the figure, 1c
Denotes a ball counter. The ball counter 1c has substantially the same configuration as that of the embodiment shown in FIGS. 1 to 3 and includes a single counting unit 6 and an upper surface of a side wall bar 13 of the counting unit 6. In that it has a device 20 for preventing the ball from being jammed. 1 to 3 for other configurations.
Since the embodiment is the same as that of the first embodiment, reference numerals are attached to the drawings, and the description is omitted.

This prevention device 20 is provided by the side wall bar described above.
A regulating plate 21 provided on the upper surface of the movable member 13 so as to be able to move forward and backward is moved forward and backward by a drive unit 22. The regulating plate 21 has reinforcing frames 24, (24), 25, and (25) attached to four sides of a plate 23 that covers part of the passage 5 of the counting unit 6 in common, and these reinforcing frames 25, ( 25), two rollers 26, 26, (26, 26) are rotatably mounted on the roller 2, and the rollers 2 of the reinforcing frame 25 shown in FIG.
A fixing pin 27 is attached between 6 and 26. These rollers 26 roll on rails 28 attached to the side wall bars 13 at both ends of the counting unit 6.

The drive unit 22 has a first link 30 rotatably mounted on a shaft 29 fixed to the side surface of the rail 28. The first link 30 has an elongated hole 30a at one end thereof. A fixing pin 27 is rotatably engaged, and a pin 31 protrudes from the other end of the first link 30. The pin 31 is rotatably mounted on a shaft 32 fixed to the side surface of the rail 28. And is engaged with one end of the second link 33. Further, the other end of the second link 33 is rotatably connected to one end of the third link 34 by a pin 35. The other end of the third link 34 is fixed via a shaft 38 to a plunger 37 of a solenoid 36 serving as a drive source. Therefore, when the solenoid 36 of the drive unit 22 is operated to move the plunger 37 forward and backward at regular intervals, the forward and backward movement is amplified via the third link 34, the second link 33, and the first link 30, The control plate 21 is moved forward and backward.

Next, the operating state of the ball counter 1c having the above-described configuration will be described. First, the power switch 10 of the ball counter 1c is turned on and other receiving conditions are checked. If there is no problem, the preparation for receiving is completed. Next, the balls 3 are put into the hopper 4 from a container containing the balls 3 discharged from a game machine such as a pachinko machine. Since the capacity of the hopper 4 is sufficiently larger than the capacity of one ball 3 in the container, the ball 3 does not overflow from the hopper 4 and the ball in the center is formed by the gentlely inclined side plate 4a. It gathers at the discharge port 11, falls from the ball discharge port 11, and falls into the counting unit 6. The ball 3 that has fallen into the counting unit 6 has a side wall bar 13 mm.
And the vehicle enters each passage 5─. At this time, each passage 5
Although the two balls 3 overlap each other because the base end of the ball 3 is deep, the balls 3 are in the passage due to the inclination of the bottom wall bar # 14 and the regulating plate 21 and the top plate 16 which gradually narrow the height of the passage 5. One for every five. The balls 3 aligned for each passage 5 are discharged one by one from the tip outlet 15. At this time, since the passage 5 is gradually narrowed, the balls 3 are not aligned one by one in this process, and a ball jam may occur. Particularly, when the inclination of the passage 5 is increased to increase the counting speed. Easy to occur.
The regulating plate 21 is a plunger formed by a solenoid 36 of the drive unit 22.
Since the reciprocating motion of 37 causes the reciprocating motion along the side wall bar 13 # constituting the passage 5, the clogging of the ball 3 is broken and thereby eliminated.

That is, the plunger 37 of the solenoid 36
The forward and backward movement of the second link 33 is made by the third link 34
About the second link 33, and a pin is
The first link 30 is rotated around the shaft 29 by contacting the first link 30 to move the regulating plate 21 forward and backward through the fixing pin 27. The light emitted from the light emitting surface of the optical sensor of the detecting unit 7 is blocked by the balls 3 one by one and does not reach the light receiving surface. The light is extracted from the transmitter as a pulse signal, and the pulse signal is displayed on the display unit 8. send.

The display unit 8 calculates the total amount of the balls 3 by adding up the pulse signals transmitted for each passage 5 and sequentially adding up the added numbers of the passages 5, and displays the result on the display panel 9. .

8 to 12 show a ball counter 1d showing an embodiment of the present invention. FIG. 8 is a perspective view of the ball counter, FIG. 9 is a side view of a main part of the ball counter, and FIG. FIG. 11 is a plan view of a main part of the ball counter, FIG. 11 is a side view similar to FIG. 9 with the counting shutter of the ball counter opened, and FIG. 12 is a perspective view of the tank. In the drawing, 1d indicates a ball counter of the present invention, and the ball counter 1d has a configuration substantially similar to the embodiment of FIGS.
The counting unit 6 (6a, 6b) is different in that it has a counting shutter 40 for controlling the flow of the balls 3 at the ball discharging ports 11 and a tank 41 for discharging a certain amount of the balls 3 downstream of the detection unit 7. . Other configurations are the same as those in the embodiment of FIGS. 1 to 3, and therefore, the drawings are denoted by reference numerals and description thereof is omitted.

The tank 41 is provided on the lower surface of the counter body 2 for receiving the balls 3 after counting, connecting a pipe or the like to the balls 3, and transferring the balls 3 to a predetermined place. The counting shutter 40 has an L-shaped plate 42 for opening and closing the opening of the ball discharge port 11 of the hopper 4 on the side of the counting unit 6b to distribute and stop the balls 3 to the counting unit 6b side. 42 is opened and closed by a drive unit 43.

The drive unit 43 has a solenoid 44 fixed to a side plate of the hopper 4 via a mounting plate 45.
The plunger 46 is rotatably connected to one end of the first link 47 by a pin 48. The other end of the first link 47 is pulled by the hopper 4 by a tension spring 49. Mounting plate
Second link 51 that rotates about a shaft 50 fixed to 45
Is rotatably connected to the first link 47 by a rotation pin 52 at the side end thereof. The L-shaped plate 42 is fixed to the end of the second link 51 as described above.

FIG. 9 shows a state in which the counting shutter 40 closes the opening of the ball discharge port 11 on the counting unit 6b side. When the second link 51 rotates around the shaft 50 in the counterclockwise direction in FIG. The character plate 42 moves to the outside of the side plate 53 of the ball discharge port 11 to open the opening on the counting unit 6b side (see FIG. 11), and the balls 3 also circulate on the counting unit 6b side. Conversely, when the second link 51 is rotated clockwise, it returns to the original position and closes the opening on the counting unit 6b side.

The tank 41 is attached to the lower surface of the counter body 2 as described above, and collects the balls 3 at the discharge port 54 by the inclined plate 41a.
Has an opening area corresponding to the processing speed of the balls 3 of various devices such as a lifter and a polishing device connected downstream thereof, so that the balls 3 having a processing speed higher than the processing speed do not come out of the discharge port 54. . The opening area of the discharge port 54 may be an opening area suitable for the counting speed of the counting unit 6 (6a, 6b) on the upstream side. In this case, the slide type shutter 55 for controlling the ball discharge amount is used. It is only necessary to mount and control the amount of discharged balls by the shutter 55.

Next, an operation state of the ball discharging machine 1d having the above configuration will be described. First, the power switch 10 of the ball counter 1d is turned on and other receiving conditions are confirmed, the counting shutter 40 is set to the open state as shown in FIG. 11, and if there is no other problem, the preparation for receiving is completed. Next, the balls 3 are put into the hopper 4 from a container containing the balls 3 discharged from a game machine such as a pachinko machine. Since the capacity of the hopper 4 is sufficiently larger than the capacity of one ball 3 in the container, the ball 3 does not overflow from the hopper 4 and the ball in the center is formed by the gentlely inclined side plate 4a. Outlet 11
Gather in Since the counting shutter 40 is open, it falls from the ball discharge port 11 and the two counting units 6a and 6
b. The balls 3 that have fallen into the two counting units 6a and 6b enter the respective paths 6 # while being regulated by the side wall bars 13 #. At this time, the two balls 3 are deeply overlapped on the base end side of each passage 6, but the balls 3 are inclined by the inclination of the bottom wall bar 14 ° and the top plate 16 which gradually narrows the height of the passage 6. Passage 6
One by one. Balls 3 arranged for each passage 6
Are discharged into the tank 41 from the tip outlets 15 and 15 one by one. The tank 41 temporarily stores the balls 3 and is sent from various devices via a pipe or the like from a discharge port 54. Discharge speed v ₁ of the balls 3 to be discharged from the outlet 54 of the tank 41, because it is almost the same as the processing speed v ₂ of the various devices, the counting speed v ₃ having each of both counting unit 6a and 6b If the relationship is v ₁ ≒ v ₂ ≒ v ₃ , the ball discharge port 11 is fully open, so that the discharge speed v ₁ of the tank 41 <the count speed 2v ₃ of the counting units 6a and 6b, and the counting speed v ₃ minutes Ball 3
Is gradually stored in the tank 41. Ball 3 is tank 41
When the inside is full, it is detected by the level detector, and a close command is issued to the drive unit 43 of the counting shutter 40. Because it moves to the middle left, the first link 48
As a result, the second link 51 rotates clockwise about the shaft 50, and the L-shaped plate 42 fixed to the end of the second link 51 is counted from the outside of the side plate 57 of the ball discharge port 11 by the ball discharge port 11. It is moved to the unit 6b side opening and closed (it becomes the state shown in FIG. 9). Therefore, the ball 3 passes through only the counting unit 6b and is reduced to about half, thereby preventing the tank 41 from overflowing with the ball 3. Thereafter, when the operation is performed in this state, and the supply of the balls 3 to the hopper 4 is not performed, the balls 3 stored in the tank 41 decrease, and finally, the tanks 3 become empty. Usually the tank 41 is for example 70
%, The level detector detects this, and issues an open command to the drive unit 43 of the counting shutter 40, and the counting shutter 40 is opened by an operation reverse to the above-described case of closing.

Therefore, the double counting speed v ₃ becomes equal to the discharge speed v.
Even if it is larger than ₁ , while the ball 3 is stored in the tank 41,
Will use the ball counting machine 1d at twice the count speed v _3, depending on the method of determining the capacity of the tank 41, or from never continues for a long time discharge speed v ₁ or more double counting speed v _3, It almost eliminates waiting for customers,
Further, it is not necessary to increase the processing speed of various devices.

[0040]

As described in detail above, according to the ball counting machine of the present invention, the balls are thrown into the hopper, collected toward the ball discharge port, and dropped from the ball discharge port to two or more counting units. 2. Dividing the balls by two or more counting units, and immediately passing the balls in each counting unit in a plurality of rows,
The balls passing through each row of these counting units are detected by the detection unit, and the number of balls can be calculated and displayed on the display unit based on signals transmitted from these detection units. Therefore, it becomes possible to provide one or more counting units in the wasted space created by providing one counting unit as in the related art, and it is possible to keep the machine height equal to or less than that. Since the inclination of the ball does not increase, ball jams hardly occur. Therefore, there is an effect that the counting speed can be totally improved.

The balls dropped from the ball discharge port of the hopper to the base end side of the counting unit are rolled from the base end side to the front end side while being rolled from the base end side to the front end side by a bottom plate arranged in a plurality of rows and inclined at a predetermined angle. As the ball goes, the ball gradually narrows and passes one by one. At this time, the ball to be jammed is broken down by the reciprocating motion of the regulating plate, and the ball moves one by one in each row. Therefore, even if the inclination of the counting unit is steep, the ball clogging phenomenon can be eliminated, the ball counting speed can be improved, the installation space can be used effectively, and the effect of shortening the ball counting time can be obtained. Can be.

Further, if the drive section comprises a solenoid and a link for amplifying the forward / backward movement of the plunger, the forward / backward movement of the solenoid amplified by the link can be directly transmitted to the regulating plate, and the forward / backward movement of the regulating plate can be controlled. Easier to do. Therefore, the prevention device can be easily manufactured as a whole.

Further, the counting shutter is fully opened, the balls thrown into the hopper are collected toward the ball discharge port, dropped from the ball discharge port to the counting unit, and the balls are arranged in a plurality of rows by the counting unit, and the balls are aligned. The number of balls was calculated and displayed on the display unit, the balls were temporarily stored in the tank, and the amount of discharged balls in the tank was provided on the downstream side. When the processing speed is almost the same as that of various devices, balls of the difference between the counting speed and the processing speed accumulate in the tank, and when the tank is full, the counting shutter is activated and the processing speed on the downstream side is equal to or higher than At the counting speed, the inside of the tank decreases, for example, when it reaches about 70% of the whole, the counting shutter is opened, and the balls are counted at the maximum counting speed. Therefore, it is almost impossible for customers to wait long for counting balls, and it is not possible to adopt a ball counting machine with a high counting speed due to the processing speed of various devices installed on the downstream side. Absent. Further, there is an effect that it is not necessary to replace various devices in order to increase the counting speed.

If the tank is provided with a shutter, the amount of discharged balls from the tank can be freely controlled in accordance with the processing speed of various devices downstream of the tank. Therefore, the ball discharging speed of the tank can be made to more easily and accurately correspond to the processing speed of various devices.
