DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an automatic nail adjustment for automatically adjusting a large number of nails planted on a game board of a ball game machine such as a pachinko machine (hereinafter referred to as a pachinko machine). About the machine.

2. Description of the Related Art Conventionally, the adjustment of a large number of nails planted on a game board of a pachinko machine has been performed manually by a skilled expert called a “nailer”.

However, this nail adjustment requires considerable experience and, as a result, there is a shortage of nailers.

Therefore, in order to automate the nail adjustment, an automatic nail adjuster was invented. However, it is necessary to fix the automatic nail adjuster so as to face the front of the game board.

As such means, it has been considered that an automatic nail adjuster is first carried by a cart and the cart is fixed in front of the pachinko machine.

[Problems to be Solved by the Invention] However, when the automatic nail adjuster is carried by the trolley as described above, a chair placed in front of the pachinko machine becomes an obstacle in a pachinko hall or the like, resulting in poor workability. .

Means for Solving the Problems Accordingly, the present invention is an automatic nail adjuster for automatically adjusting a nail implanted in a game board of a ball game machine, such as an image processing sensor for actually measuring the position of the nail. A locking member is provided on the frame supporting the functional portion of the game machine, and a hooking member is provided on the island where a number of ball game machines are juxtaposed, and the hooking member is installed on the island by engaging the locking portion of the frame. The present invention provides an automatic nail adjuster for a ball game machine, which can be installed so as to face a game board surface of the ball game machine.

[Function] By fixing the support means for supporting the functional part such as the nail position measuring means to the game machine by the fixing means, the functional part can be installed facing the game board surface of the ball-and-ball game machine.

Example An example of the present invention will be described below with reference to the drawings.

The frame 1 supporting each functional part (such as a nail holder 18a and a camera 17 described later) includes two parallel vertical rods 1a, 1a, a horizontal connecting pipe 1b connecting the vertical rods 1a, 1a, and a vertical rod 1a. It is composed of traverse feed screw shafts 1c, 1c which are rotated forward and reverse by traverse feed motors 2, 2 mounted on the motor. The vertical rods 1a, 1a are formed such that the upper ends are bent in an inverted U-shape to form a locking portion 1d. The pachinko machine P is installed facing the front surface of the pachinko machine P by hooking the locking portions 1d of the vertical rods 1a. Further, vacuum suction devices 4, 4 are provided at the lower ends of the vertical rods 1a, 1a. The vacuum suction devices 4 and 4 are configured such that lower portions of the left and right vertical rods 1a and 1a are formed in a pipe shape and suction pads 5 and 5 are provided at the ends thereof. And further connect pipe 1b
Is connected to the hose 7 of the adsorber 6 at one end. The suction disks 5, 5 of the vacuum suction devices 4, 4 are sucked to the curtain plate 8 below the pachinko machine P to firmly fix the frame 1.

Movable supports 9 and 10 are screwed to the lateral feed screw shafts 1c and 1c, respectively, and the upper and lower movable supports 9 and 10 are connected by a vertical feed screw shaft 11 and a vertical guide rod 12. Vertical feed screw shaft 11
Is rotated forward and reverse by a vertical feed motor 13 provided on the upper movable support 9. The vertical feed screw shaft 11 and the vertical guide rod 12
Image processing sensor 1 that actually measures the positions of nails 15, 15,.
6 and a nail bending means 18 for bending the nail 15 by applying a lateral load to the nail 15 while engaging the head 15a of the nail 15.
Is mounted. The camera 17 and the nail holder 18a are housed in a single casing 19. When the casing 19 moves up and down with the rotation of the vertical feed screw shaft 11, the camera 17 and the nail holder 18a also move in the vertical direction together. Further, the vertical feed screw shaft 11 and the vertical guide rod 12 move laterally integrally with the movement of the movable abutments 9, 10 by the rotation of the horizontal feed screw shafts 1c, 1c. Therefore, the camera 17 and the nail holder 18a can face any part of the game board 14 by the lateral movement of the movable supports 9 and 10 and the vertical movement of the casing 19.

The image processing sensor 16 comprises a camera 17, a CRT 20 for displaying an image of the camera 17, and an analysis program for detecting xy coordinates of the nails 15, 15,... On the CRT 20. It is sufficient for the image processing sensor 16 to use existing technology as it is.

The actual measurement value of the xy coordinate of the nail 15 actually measured by the image processing sensor 16 is stored in the storage means 22a of the computer 22 installed on the movable carriage 21.

The nail bending means 18 is constituted by a combination of a lateral feed screw shaft 1c, 1c and its lateral feed motor 2, 2, a vertical feed screw shaft 11, a vertical feed motor 13, and a nail holder 18a provided in a casing 19. It is. Of these, the nail holder 18a is the fourth and fifth
As shown in the figure, a concave portion 23 that can be loosely fitted to the head 15a of the nail 15 is provided at the tip thereof, and the tip is advanced by driving a motor 24 provided in the casing 19 to engage with the head 15a of the nail 15. Is what you do. In this case, the operating rod 25a of the nail sensor 25 faces the recess 23, and when the nail holder 18a engages with the nail 15 to a certain depth, the motor 24 is stopped and the nail holder 18 is stopped.
I try to stop a. Then, the vertical feed motor 13 and the horizontal feed motors 2, 2 are driven while the head 15a of the nail 15 is engaged with the nail holder 18a in this manner, and the nail holder 1 is driven.
The nail 8 is forcibly bent by moving 8a in an arbitrary direction.

As described above, the vertical feed motor 13, the horizontal feed motors 2, 2, and the motor 24 for moving the nail holder 18a back and forth are all computer 22
Is controlled by the control means 27.

Further, the computer 22 is provided with a comparison means 29 for comparing nail data specifying the position of the xy coordinate of the nail 15 with an actually measured value measured by the image processing sensor 16.
The comparing means 29 and the control means 27 form a part of the central processing unit 30 of the computer 22.

Next, the flow of the nail adjustment of the pachinko machine Px of the machine number X will be described with reference to the flowcharts of FIGS.

In step (1), first, the storage device 22a of the computer 22
The nail data of the day before of the pachinko machine Px is read. Then, in steps (2), (3) and (4), nail data of the day corresponding to the pachinko machine Px is selected and read into the storage device 22a.
Here, the “ball pitch” in step (2) is assigned to each of the pachinko machines P, P... Based on the entire ball pitch determined by the business policy of the game arcade or the average ball pitch for each island S. It is something that can be done. Further, “selection of nail data corresponding to the pitching rate” in step (3) means that the test hitting is performed in advance in accordance with the pitching rate based on the pitching rate determined in step (2). Or the pattern of nail data that is obtained from actual measured values in business or the like. That is, since nail data patterns corresponding to the odds of 80%, 90%, and 100% have already been obtained, select nail data corresponding to the throwing rate determined in step (2). I just need to. When reading of the nail data of the previous day and the nail data of the current day into the storage device 22a is completed in this way, a display to that effect is made in step (5).

Next, in step (6), the automatic nail adjuster is used for the pachinko machine.
Waiting to be installed before Px. To install the pachinko machine Px, open the glass frame 32 of the pachinko machine Px, and set the vertical rods 1a, 1a
Hook 1d on the hook member 3 of the island S, and
This is performed by adsorbing the suction disks 5, 5 at the lower end of 1a, 1a to the curtain plate 8 below the pachinko machine Px.

When the installation of the automatic nail adjuster is completed, an input as to whether or not to change the nail data is awaited in step (7). This is required when moving to the next pachinko machine P _{X + 1} and changing the nail data. It is made to correspond.

When the start button is pressed in step (8), first, in step (9), the casing 19 moves to the lower side of the game board 14 to search for the reference point studs 31, 31 (step (1)
0)). Based on the positions of the reference point studs 31,31,
Actually measure or bend 15,15 ...

In step (11), the camera 17 is moved to the block of the game board 14. The term “block” refers to an area in which the game board 14 is sectioned by an appropriate size, and a range in which the camera 17 captures images at one time. The measurement accuracy improves as the range becomes narrower.

In step (12), the positions of the nails 15, 15,... Are actually measured by the image processing sensor 16 to obtain xy coordinates. Then, the actual measurement value is compared with the nail data of the present day read in step (4), and the comparing means 29 determines whether there is a mismatched nail 15 or not. If the xy coordinates of the two do not match, the nail 15 is displayed in the CRT 20 in a different color as the nail 15 to be adjusted (step (14). Next, it is determined in step (15) whether the mismatch is within the reference value. Here, the "reference value" is the maximum value that can be adjusted by the nail bending means 18. Even when the nail 15 has fallen, the nail 15 is processed as a value outside the reference value. In step (16), an indication that the nail 15 is abnormal is displayed on the CRT 20 and is skipped to proceed to the next nail or the next block. Workers will have to deal with it.

If the displacement of the nail 15 is within the reference value in step (15), the nail holder 18a is moved to the position of the target nail 15 in step (17). The control means 27 controls the rotation speed and rotation direction of the transverse feed motors 2, 2 and the rotation speed and rotation direction of the vertical feed motor 13 so that the nail holder 18a reaches the position of the xy coordinate based on the actually measured value of the nail 15 respectively. When the control is performed and it is confirmed in step (18) that the nail holder 18a has reached the position of the corresponding nail 15, the nail holder 18a stops in step (19). Next, in step (20), the motor 24 is driven, and the nail holder 18a
To move forward. Since the nail holder 18a is in front of the nail 15 as a result of the movement based on the actually measured value, the head 15a of the nail 15 fits into the concave portion 23 as the nail holder 18a advances.
Then, the operating rod 25a protruding into the concave portion 23 is pushed, the nail sensor 25 senses, and the motor 24 stops (steps (21), (22)).

In this state, the nail bending means 18 operates in step (23). That is, the nail holder 18a is forcibly moved to bend the nail 15 to the position of the xy coordinate of the nail data, and the nail 15 is plastically deformed. At this time, since the nail 15 has a phenomenon that the nail 15 slightly returns due to elasticity, it is necessary to bend the nail 15 by an amount that takes this phenomenon into consideration (step (24)). When the nail 15 is raised, the head 15a of the nail 15 gradually becomes higher. However, if the recess 23 is made deeper as shown in FIG. 4, the head 15a of the nail 15 becomes deeper in the recess 23. The nail 15 stands up without any trouble. Also. Conversely, nail 15 may be knocked down,
In this case, the head 15a of the nail 15 gradually lowers and tends to come off the recess 23, but this is taken into account from the beginning and the head
The nail holder 18a may be advanced by the motor 24 in accordance with the movement of the head 15a, by inserting the 15a deep into the recess 23.

After bending of the nail 15 is completed in this way, step (2)
In 5), it is further determined whether there is a mismatched nail 15 in the block, and if there is, the process returns to step (15) and the same operation as described above is repeated. Mismatched nails in block in step (25)
If it is determined that 15 has been lost, it is determined in step (26) whether all blocks have been completed, and if there are remaining, the camera 17 is moved to the next block in step (27) and jumped to step (12). The same operation is repeated. Also step (2
If it is determined in step 6) that all blocks have been completed, the camera 17 and nail holder 18a are returned to their original positions in step (28). Then, in step (29), the next pachinko machine P _{X + 1}
To continue and enter the same work, and if so, return to step (6) to perform the same work; otherwise, end.

Note that the nail data of the previous day is used when determining the pitching rate or when quickly determining a block that needs adjustment. In addition, a bar code 33 indicating gauge information of the game board 14 is printed on the celluloid plate adhered to the surface of the game board 14, and the bar code 33 is read by the image processing sensor 16 so that the nail data is incorrect. Check if there is any.

FIG. 8 shows another embodiment of the hanging member 3, in which the hanging member 3 is provided on the inner surface of the opening 35 of the curtain plate 34 of the island S. Island S without discomfort
Can be mounted on Note that a cover plate 36 is provided in the opening 35.

In this embodiment, the frame 1 corresponds to the support means,
The locking portion 1d, the hanging member 3, the suction disk 5 of the vacuum suction device 4, and the like correspond to fixing means.

[Effects of the Invention] According to the automatic nail adjuster of the present invention, it is possible to easily install a functional portion such as a nail position measuring means on a game board surface of a ball game machine with a simple configuration. . Thereby, in a pachinko hall or the like, a problem that a chair placed in front of the pachinko machine becomes an obstacle is prevented beforehand, and an extremely excellent effect that work efficiency can be remarkably improved can be achieved.

In addition, since the functional parts such as the nail position measuring means are fixed to the ball game machine by the fixing means via the supporting means, it is possible to eliminate the position error of the functional parts such as the error of the measuring position by the nail position measuring means. There is also an excellent effect that the accuracy of nail adjustment can be further improved.
