Description

Description: TECHNICAL FIELD The present invention relates to an automatic nail adjusting device for automatically adjusting a large number of nails driven into a game board of a ball game machine such as a pachinko machine.

[Conventional technology]

Conventionally, the adjustment of a large number of nails arranged on the game board of a ball game machine has been performed manually by a skilled expert, but it corrects the poor workability, the adverse effect of lacking objective accuracy, etc. The applicant has filed an application for an automatic nail adjuster as Japanese Patent Application No. 1-42863.

This automatic nail adjuster includes measuring means for actually measuring the position of the nail on the game board, nail data specifying the position of the nail, comparing means for comparing the nail data with the actually measured value, and applying a load to a part of the nail. It comprises nail bending means for bending the nail in addition, and control means for moving the nail bending means to an arbitrary position on the game board surface,
The nail data and the measured value are compared by the comparing means. If the two do not match, the control means is actuated based on the measured value to move the nail bending means to the target nail position, and to a part of the nail by the nail bending means. The nail is bent by applying a load until it matches the nail position in the nail data.

[Problems to be solved by the invention]

In the conventional automatic nail adjuster described above, only one bending portion is provided for each nail. Therefore, no matter how much the working speed was improved, it became clear that it took a considerable amount of time to process one game board because the number of nails on the game board was too large.

In order to solve such a problem, it is conceivable to arrange a plurality of automatic nail adjusters and process a plurality of game boards at the same time, but in such a case, the machine installation area becomes large and it must be used in a small factory etc. However, another problem such as an increase in cost is caused.

[Means for solving the problem]

In order to solve the above problems, the present invention provides a measuring means for actually measuring the position of a nail on a game board, nail data specifying a position of a nail, a comparing means for comparing the nail data with an actually measured value, Equipped with at least two or more nail bending machines consisting of nail bending means for bending a nail by applying a load to a part thereof, and control means for moving the nail bending means to an arbitrary position on the game board surface,
Each nail bending machine compares the nail data with the actually measured value by the comparing means, and when the two do not match, activates the control means based on the actually measured value to move the nail bending means to the target nail position and simultaneously perform the nail bending. By applying a load to a part of the nail by means to bend the nail until it coincides with the nail position in the nail data, furthermore, by operating each nail bending machine independently, a single game board can be connected to a plurality of nails. An object of the present invention is to provide an automatic nail adjusting device for a game board for a ball game machine, which is adjusted in parallel with a music machine.

[Action]

 Each nail bending machine works independently as follows.

The position of the nail on the game board is read and stored as xy coordinates by the measuring means. On the other hand, nail data specifying the position where the nail should be located is stored as xy coordinates in the storage device, and the nail data is compared with the actual measurement value by the comparing means. If it is determined that the two do not match, first, the control means is operated to move the nail bending means to the position of the xy coordinate of the actually measured value. Next, after the nail bending means is brought into contact with a part of the nail, the control means forcibly moves the nail bending means in the direction of the xy coordinate of the nail data to bend the nail. The nail bending means bends the nail until it matches the position of the xy coordinate of the nail data, and then moves to the next target nail.

The tip of the nail 16 is moved down by the drive of 16 to engage with the head 8a of the nail 8. In this case, the nail sensor is
When the nail holder 11a engages with the nail 8 to a certain depth, the motor 16 is stopped to stop the nail holder 11a. The motor 4 and the like are driven while the head 8a of the nail 8 is engaged with the nail holder 11a as described above, and the nail 8 is forcibly bent by moving the nail holder 11a in an arbitrary direction.

As described above, guide rails 2, 2, sliding grooves 3a, 3b, screw shafts 5, 5
, Two nail curves A1 and A2 are schematically formed by the motors 4 and 4 for rotating the screw shafts 5 and 5, the moving frames 6a and 6b, the casing 12, the motor 12a, the nail holder 11a and the camera 10, respectively. You. Then, motors 4, 4 for moving the moving frames 6a, 6b
The motor 12a for moving the casing 12 and the like are all independently controlled by the control means 18 of one computer 14.

The computer 14 is provided with a comparing means 19 for comparing nail data specifying the position of the xy coordinate of the nail 8 with an actually measured value measured by the measuring means 9. This means of comparison
The control unit 18 and the control unit 18 form a part of the central processing unit 20 of the computer 14.

Next, the operation will be described with reference to the flowcharts of FIGS. 5 (a) and 5 (b). The two nailing machines A1 and A2 operate independently of each other, but since their functions are exactly the same, only one nailing machine A1 will be described.

At the stage of step (1), the game board B has not been set, and a CRT display indicating that nail data is input to the storage device 14a of the computer 14 is displayed. Here, the nail data is the nail data of the nail 8 used in the automatic nailing machine if all the nails 8 are adjusted vertically at the time of shipment from the factory.
The xy coordinate data may be used as it is. In addition, if the nail is adjusted so that the ball pitch is 80%, nail data set based on data obtained by an empirical rule, test hitting, or the like is input. These series of operations are performed from step (1) to
This is performed in (5).

At step (6), it is confirmed whether the game board B is set on the frame 1. This may be appropriately detected by a sensor, or may be manually input by the operator.

In step (7), it is checked whether the nail data has been changed. For example, this is to deal with a case where the pitching rate is changed from 80% to 70%.

When the preparation is completed in steps (1) to (7) and the start input is confirmed in step (8), first, in step (9), the camera 10 of the measuring means 9 moves to one block of the game board B. Moving. Then, when the camera 10 faces a predetermined block, the video is sent to the computer 14 and the xy coordinates of the nail 8 can be measured according to the image analysis program.
This measured value is stored in the storage device 14a of the computer 14.

In step (11), the comparison between the previously input nail data and the actually measured value in step (10) is performed by the comparison means. If the xy coordinates of the two do not match, the nail 8 is displayed as a nail to be adjusted on the CRT 13 in a different color (step (1)
2)).

Next, in step (13), it is determined whether the mismatch is within the reference value. Here, the reference value is a range that can be corrected by the nail bending means 11, and even when the nail 8 is dropped due to an error in the automatic nailing machine, the nail 8 is processed as a value outside the reference value.
This processing is to display on the CRT 13 that the nail 8 is abnormal in the step (14), skip this, and proceed to the next nail or the next block. Workers will deal with nails 8 outside this reference value later based on the CRT display.

If the deviation of the nail 8 is within the reference value in step (13), the nail bending means 11 is moved to the position of the target nail 8 in step (15). When it is confirmed in step (16) that the nail holder 11a has reached the position of the corresponding nail 8, the nail bending means 11 stops in step (17). Next step (18)
To drive the motor 16 to lower the nail holder 11a.
The nail holder 11a moves on the basis of the actually measured value and is located right above the nail 8 to be targeted, so that the head 8a of the nail 8 fits into the concave portion 15 by lowering the nail holder 11a. Then, the working rod 17a protruding into the concave portion 15 is pushed and the nail sensor 17 senses,
The motor 16 stops (steps (19) and (20)).

In this state, the nail bending means 11 operates in step (21). That is, the nail holder 11a is forcibly moved to bend the nail 8 to the position of the xy coordinate of the nail data. At this time, since the nail 8 has a phenomenon that the nail 8 slightly returns due to elasticity, it is necessary to bend the nail by an amount that takes such phenomenon into consideration (step (22)).

After the bending of the nail 8 is completed in this way, it is determined in step (23) whether there is any unmatched nail 8 in the block, and if there is, the process returns to step (13) to repeat the same operation as described above. If it is determined in step (23) that there are no more unmatched nails 8 in the block, it is determined in step (24) whether all blocks have been completed, and if there are any remaining, the camera 10 is moved to the next block in step (25). Move to step (10) and repeat the same operation. If it is determined in step (24) that all blocks have been completed, the camera 10 and nail holder 11a are returned to their original positions in step (26), and the game board B is removed. Then, in step (27), the player changes the game board B and inputs whether to continue the same operation. If the operation is to be continued, the process returns to step (6) to perform the same operation.

A bar code 21 representing the gate information of the game board B may be printed on the celluloid plate attached to the surface of the game board B, and the bar code 21 may be read by the measuring means 9 to input nail data. Good.

〔The invention's effect〕

As described above, according to the present invention, the nail bending machines A1 and A2 are controlled by the computer 14 and operate independently of each other, so that the processing speed of the nail adjustment can be greatly improved. Moreover, as compared with the case where a plurality of conventional automatic nail adjusters are installed to improve the processing speed, the installation space can be reduced, and the number of parts can be significantly reduced to reduce costs. effective.
