The present invention relates to a pachinko ball passing sensor that detects the passage of a pachinko ball by adopting the principle of a proximity sensor and a pachinko ball counting device using the sensor.
[0002]
[Prior art]
Usually, a pachinko amusement hall is equipped with a payment device for an acquired pachinko ball called a jet counter. As shown in FIG. 13, this pachinko ball settlement apparatus is provided with a hopper 2 for introducing the pachinko balls P on the upper surface side of the main body case 1, and the pachinko balls P introduced into the hopper 2 1 falls on the pachinko ball alignment plate 3 supported in an inclined posture and flows in an aligned state on the counting lane 4 on the downstream side of the pachinko ball alignment plate 3, and on the downstream side of the counting lane 4 for each row. Passage is detected by the pachinko ball passing sensor 5 provided, and the number of balls out of the pachinko ball P is counted.
[0003]
As the pachinko ball passage sensor 5, a photo sensor has been well known. In FIG. 14, a light-shielded photosensor is used, and a sensor substrate 6 is attached on the downstream side of the counting lane 4 so as to extend in the vertical direction, and passes through the sensor substrate 6. A projector 6a and a light receiver 6b are respectively provided at the vertically symmetrical positions of the pachinko ball P. And if the pachinko ball P passes, the passage of the pachinko ball P is detected by blocking the light from the projector 6a.
[0004]
Further, in the reflection type photosensor shown in FIG. 15, a sensor substrate 7 is attached on the downstream side of the counting lane 4 along the flow direction of the pachinko balls P, and a light projector 7 a and a light receiver 7 b are mounted on the lower surface of the sensor substrate 7. The pachinko ball P is provided at a predetermined interval along the passing direction of the pachinko ball P, and when the pachinko ball P passes through the sensor portion, the light from the light projector 7a is reflected by the pachinko ball P and reaches the light receiver 7b. Thus, the passage of the pachinko ball P is detected.
[0005]
[Problems to be solved by the invention]
Thus, when the conventional photosensor shown in FIGS. 14 and 15 is used as the pachinko ball passing sensor 5 used in the pachinko ball P counting device, the light projecting / receiving device 6a, If dirt due to oil, water vapor, dust, etc. adheres to 6b, 7a, 7b, it is fatal, so it is necessary to perform work to remove the dirt frequently due to restrictions on the use environment, and maintenance is troublesome. Disadvantages have been pointed out.
[0006]
In addition, even strong ambient illumination light is easily affected and may malfunction, and a structure such as a light shielding plate is required to prevent this, and the structure tends to be complicated and large.
[0007]
Further, when the light-shielding photosensor shown in FIG. 14 is used, the sensor substrate 6 is installed to extend in the vertical direction, and the projector 6a and the light receiver 6b are respectively positioned on the vertical side of the pachinko ball P passage. A large amount of installation space is required, and the apparatus is disadvantageous in that the apparatus becomes large.
[0008]
On the other hand, when the reflection type photosensor shown in FIG. 15 is used, there is a possibility that malfunction may occur due to dirt on the pachinko ball P, and there is a drawback that good detection accuracy cannot be secured.
[0009]

[0012]
Therefore, according to the first aspect of the present invention, the pachinko ball passing through each of the two lanes is passed through the pachinko ball provided in each of the two sensor head portions protruding from the sensor mounting base portion. When passing through the hole, the inductance of the coil of each sensor head changes, and the passage of the pachinko ball can be detected, so it is not affected by the dirt of the sensor part, so maintenance is not troublesome and the pachinko ball is dirty. Even if it adheres, it does not malfunction, and the passage of pachinko balls flowing through each of the two lanes can be detected with high accuracy.
[0013]
In addition, since the sensor mounting base portion mounted so as to straddle two rows of lanes has two sensor head portions and each sensor head portion shares the sensor mounting base portion, it is more compact. It becomes a structure.
[0014]
Further, in the pair of coils embedded in the two sensor head portions, the right winding conductor of one coil and the left winding conductor of the other coil are located on the boundary line of the counting lane. Therefore, the thickness of the sorting rib can be reduced.

The pachinko ball passing sensor according to claim 1 , wherein each of the left and right sensor heads is attached to the pair of sensor head attachment parts,
It is characterized by comprising.
[0016]
Therefore, according to the invention described in claim 2 , the width dimension of the pachinko ball passing sensor attached to the counting lane located on the downstream side of the pachinko ball alignment plate can be shortened, and accordingly, the thickness of the sorting rib is reduced. Since it can be made thin, the entire width of the counting lane can be shortened, and the pachinko ball counting device can be made compact.
[0017]
Furthermore, since the thickness of the sorting ribs can be set thin, there is no clogging at the upstream side of the sorting ribs, and pachinko balls can flow linearly from the upstream of the pachinko ball alignment plate to the downstream of the counting lane, making smooth pachinko balls The flow can be accelerated and the pachinko ball counting process can be performed quickly.
[0018]
The invention according to claim 3 of this application is characterized in that the shifting distance of the left and right sensor heads in the counting lane extending direction is larger than the mutual interference distance of the proximity sensor.
[0019]
According to the third aspect of the present invention, since the shift distance in the extending direction of the adjacent sensor head portions is set larger than the mutual interference distance of the proximity sensors, pachinko balls are placed in the adjacent counting lanes. Even if it passes, there is no mutual interference in the inductance change of the adjacent coil, and malfunction due to the ball passing in the adjacent lane does not occur.
[0020]

Then, when the pachinko ball P passes through the pachinko ball passage hole 33 of the pachinko ball passage sensor 30 for each counting lane 21, the coil 34 embedded in the sensor head portion 32 so as to surround the pachinko ball passage hole 33. When the inductance value changes, the passage of the pachinko ball P is detected, and the total count is displayed on the display unit 15 of the pachinko ball counting device 10 shown in FIG.
[0033]
Therefore, unlike the conventional photo sensor type pachinko ball passing sensor, it is not necessary to clean the projector / receiver frequently, so that maintenance is not required and management is easy.
[0034]
Further, unlike conventional photosensors, there is no need for incidental equipment such as a light shielding plate for eliminating adverse effects from ambient illumination light and sunlight, and sensor mounting is performed so that the sensor head portion 32 faces the counting lane 21. Since the base portion 31 is attached in parallel with the floor surface of the counting lane 21, the installation space may be only the thickness of the sensor attachment portion 31 attached on the counting lane 21, and the pachinko ball counting device 10 as compared with the conventional photosensor. Therefore, the installation space for the pachinko ball counting device 10 can be reduced, which contributes to space saving.

It is an improved point.
[0037]
That is, the pachinko ball passing sensor 40 has a width corresponding to the two counting lanes 21 and 21 and is attached to the upper part of the counting lane 21 so as to face the floor of the counting lane 21 in parallel. It is composed of a resin integrated molded product including a base portion 41 and two sensor head portions 42a and 42b that project from the sensor mounting base portion 41 and are interposed in the middle of each of the two counting lanes. ing.
[0038]
The individual sensor head portions 42a and 42b are provided with pachinko ball passage holes 43a and 43b for allowing the pachinko balls P to pass therethrough, and LC so as to surround the pachinko ball passage holes 43a and 43b. Coils 44a and 44b serving as inductance elements of the oscillation circuit are embedded.
[0039]
In addition, a conductor portion for leading the terminal of each coil 44 to the outside is embedded in the sensor mounting base portion 41, and this conductor portion is connected to an external harness through a connector or the like from the outer surface of the mounting base portion 41, for example. In addition, a mounting hole 46 is formed in the sensor mounting base portion 41, and a stepped portion 47 that fits with a corner portion of the adjacent sensor mounting base portion 41 is set on one side edge of the sensor mounting base portion 41. Has been.
[0040]
FIG. 6 is a perspective view of the pachinko ball passage sensor 40 as viewed from the ball passage side. The inner surface of the sensor mounting base 41 is directed to the pachinko ball passage holes 43a and 43b corresponding to the counting lane 21. Inclined guide ribs 48a and 48b are provided so that a smooth ball flow can be expected.
[0041]
By the way, the two sensor head portions 42a and 42b are arranged at a certain distance along the extending direction of each counting lane 21, that is, the flow direction of the pachinko balls P, and shifted by the dimension b in FIG. The right winding conductor 44bR of the coil 44b embedded in the sensor head portion 42b and the left winding conductor 44aL of the coil 44a embedded in the right sensor head portion 42a are on the boundary line of the counting lane 21, that is, on the sorting ribs 22. They are set to overlap (see FIG. 7B).
[0042]
On the other hand, as shown in FIGS. 8 and 9, the pachinko ball alignment plate 20 to which the pachinko ball passage sensor 40 is attached has a plurality of rows (eight rows) on the downstream side of the pachinko ball alignment plate 20 by a plurality of sorting ribs 22. ) And the notches 24a are formed on the downstream end side of the odd-numbered counting lanes 21a so as to correspond to the sensor head portions 42a and 42b of the pachinko ball passing sensor 40. In addition, openings 24b are formed in the even-numbered counting lanes 21b at positions shifted by b in the upstream side.
[0043]
The pachinko ball passing sensor 40 is mounted on the downstream side of the counting lane 21 so that the sensor heads 42a and 42b of the pachinko ball passing sensor 40 are accommodated in the notches 24a and the openings 24b serving as sensor head mounting portions. Yes.
[0044]
Next, the usage pattern of the pachinko ball passage sensor 40 in the second embodiment will be described. The pachinko balls P introduced into the hopper 12 of the counting device 10 (not shown in FIG. 10) fall on the pachinko ball alignment plate 20, Due to the inclination of the pachinko ball alignment plate 20, it flows in the direction of the arrow in FIG. 11. At that time, it is separated for each column by the sorting rib 22, and flows downstream on each counting lane 21 in the aligned state. The pachinko ball P flowing on the counting lane 21a passes through the pachinko ball passage hole 43a of the sensor head portion 42a of the pachinko ball passage sensor 40, and at this time, the passage of the pachinko ball P is detected by the change in inductance of the coil 44a.
[0045]
On the other hand, the pachinko balls P flowing through the even-numbered counting lanes 21b pass through the pachinko ball passage holes 43a of the sensor head portion 42b located on the front side, and at this time, the passage of the pachinko balls P is detected by the inductance change of the coil 44b. Will be.
[0046]
Therefore, the pachinko ball passage sensor 40 of the second embodiment also uses the principle of the proximity sensor, like the pachinko ball passage sensor 30 of the first embodiment. There is an advantage that it is possible to detect the passage of the pachinko ball P with high accuracy without being affected even if the pachinko ball P is dirty.
[0047]
Furthermore, compared to the pachinko ball passing sensor 30 of the first embodiment, the two sensor head portions 42a and 42b are integrated, so that the configuration is more compact, and it is excellent in space saving, and the internal conductor substrate portion is also shared. Since the mounting time can be shortened, the assembly cost and the harness cost can be saved, and the like, and the sensor mounting base 41 is attached to the two adjacent rows of counting lanes 21 by crotch. Mounting workability is also excellent.
[0048]
Further, as shown in FIG. 6, the right winding conductor 44bR of the coil 44b embedded in the left sensor head 42b and the left winding conductor 44aL of the coil 44a embedded in the right sensor head portion 42a are arranged on the sorting ribs 22. Since they overlap, the sorting ribs 22 can be shared. Further, since the adjacent pachinko ball passing sensor 40 can be shortened in the width direction by the step 47, the thickness of the sorting ribs 22 can be reduced. Since the entire width of 21 can be reduced, the pachinko ball counting apparatus 10 can be further reduced in size, and there is an advantage that it can be effectively applied in a narrow space of a playground.
[0049]
In addition, since the sorting ribs 22 can be regulated thinly, the flow of the pachinko balls P does not incline in the horizontal direction even in the counting lanes 21 in the outer row, becomes linear, and does not clog the pachinko balls P. It can flow smoothly on the top and perform a quick counting process, and the pachinko balls P and the partition ribs 22 are less likely to come into contact with each other, and wear of the sorting ribs 22 can be suppressed.
[0050]
Further, in the pachinko ball passing sensor 40, the guide ribs 48a and 48b are provided on the inner surface of the sensor mounting base 41 corresponding to the counting lanes 21, so that, for example, when there are no guide ribs 48a and 48b, FIG. As shown in FIG. 12A, although the pachinko ball P jumps upward in front of the pachinko ball passage hole 43a and may cause clogging, as shown in FIG. 12B, the guide ribs 48a and 48b Even if the pachinko ball jumps upward, the pachinko ball P is smoothly guided into the pachinko ball passage holes 43a and 43b, and a good ball flow can be expected.
