Therefore, since the obstacle nail 200 is also erected with the head 200b side tilted upward by about 4 degrees with respect to the Z axis (perpendicular line), the game ball P colliding with the obstacle nail 200 is placed on the game board 2 side as much as possible. I try to bounce back.

As shown in FIG. 3B, for example, the distance dimension L2 on the base side of the body portion 200a of the left and right obstacle nails 200 constituting the designated nail 204 is set to about 10.5 mm (L2 = about 10.5 mm). Since the separation dimension L3 on the tip end side is about 12 mm (L3 = about 12 mm), the separation dimension of the left and right body portions 200a gradually increases from the game board surface 2a toward the head 200b. Further, the diameter PD of the game ball P is set to be about 11 mm (for example, PD = about 11 mm), and the game ball P passes between the body portions 200a of the left and right obstacle nails 200 in a state of being in contact with the game board surface 2a. Can be done.

In the above, the designated nail 204 corresponding to the first starting winning opening is illustrated, but the other designated nails 205 to 208 have different separation dimensions L3. Specifically, the designated nail 205 corresponding to the general winning opening 60 has a separation dimension L3 of 11.4 mm, the designated nail 206 corresponding to the gate 41 has a separation dimension L3 of 12.8 mm, and the designated nail 207 corresponding to the wind turbine 61. The separation dimension L3 is 11.5 mm, and the separation dimension L3 is 11.1 mm for the designated nail 208 corresponding to the warp passage 62. The separation dimensions L3 of the designated nails 204 to 208 exemplified above are merely examples, and these separation dimensions L3 are exemplified above according to the gauge configuration (so-called nail arrangement) of the game board 2. It is possible to change to a dimension other than the separated dimension L3. For example, the separation dimension L3 of the designated nail 204 may be a dimension larger than about 12.0 mm or a dimension smaller than about 12.0 mm.

Returning to FIG. 1, at the lowermost part of the game area 10, an out port 11 is provided in which a game ball that has not entered any of the winning openings is taken in. Speakers 8L and 8R for reproducing and outputting sound effects and the like are provided at the upper left and right positions of the gaming machine frame 3, and an effect LED 9 is provided at the peripheral portion of the gaming area 10.

Next, the circuit configuration of the pachinko gaming machine 1 will be described. On the back surface of the pachinko gaming machine 1, for example, a main board (not shown), an effect control board, a voice control board, an LED control board, and a relay for relaying various control signals transmitted between the main board and the effect control board. Various boards such as a board, a payout control board, an information terminal board, a launch control board, and an interface board are arranged.

The main board (not shown) is a control board on the main side, and is equipped with various circuits for controlling the progress of the game in the pachinko gaming machine 1. The main board is mainly a sub-side control board consisting of a random number setting function used in a special figure game, a function of inputting a signal from a switch or the like arranged at a predetermined position, an effect control board (not shown), and the like. It is equipped with a function to output and send a control command, which is an example of command information, as a control signal, and a function to output various information to the hall management computer. Further, the main board controls lighting / extinguishing of each LED (for example, segment LED) constituting the first special symbol display 4A and the second special symbol display 4B to control the lighting / extinguishing of the first special symbol and the second special symbol. Controls the variable display of a predetermined display symbol, such as controlling the variable display and controlling the variable display of the normal symbol by the normal symbol display 20 by controlling the lighting / extinguishing / coloring of the normal symbol display 20. It also has a function to do. Further, various circuits such as a game control microcomputer (not shown), a switch circuit (not shown), and a solenoid circuit are mounted on the main board.

A gate switch for detecting a game ball that has passed through the passage gate 41, a first start port switch, a second start port switch, and a wiring for transmitting detection signals from the count switch are connected to the main board. In addition, display control of the first special symbol display 4A, the second special symbol display 4B, the normal symbol display 20, the first hold display 25A, the second hold display 25B, the normal figure hold display 25C, and the like is performed. The wiring that transmits the command signal for is connected.

The control command transmitted from the main board to the effect control board via the relay board is, for example, an effect control command transmitted and received as an electric signal. The effect control command includes, for example, a variation pattern designation command indicating a variation pattern indicating a variation mode such as a variation time of the effect symbol, a type of reach effect, and the presence / absence of a pseudo-ream.

The game control microcomputer mounted on the main board is, for example, a one-chip microcomputer, which is a ROM (ReadOnlyMemory) for storing game control programs and fixed data, and a RAM for providing a game control work area. (RandomAccessMemory102), a CPU (CentralProcessingUnit) that executes a game control program to perform control operations, a random number circuit that updates numerical data indicating random values independently of the CPU, and I / O (Input /). Outputport), and is configured with. As an example, in the game control microcomputer, a process for controlling the progress of the game in the pachinko gaming machine 1 is executed by executing a program read from the ROM by the CPU.

The effect control board (not shown) is a control board on the sub side independent of the main board, receives a control signal transmitted from the main board via the relay board, and receives the effect display device 5, speakers 8L, and 8R. In addition, various circuits for controlling the production operation by the production electrical parts such as various motors, solenoids, sensors, and light emitting diodes (LEDs) provided in the production LED9 and other production units are mounted.

The effect control board (not shown) includes a effect control CPU that performs control operations according to a program, a ROM that stores the effect control program, fixed data, and the like, and a RAM that provides a work area for the effect control CPU. A display control unit that executes processing for determining the control content of the display operation in the effect display device 5, a random number circuit that updates numerical data indicating a random value independently of the effect control CPU, and I / O. O is installed. As an example, in the effect control board, a process for controlling the effect operation by the effect electric component is executed by executing the effect control program read from the ROM by the effect control CPU. Further, in the ROM, in addition to the effect control program, various data tables used for controlling the effect operation are stored.

Next, the progress of the game in the pachinko gaming machine 1 will be schematically described. In the pachinko gaming machine 1, based on the fact that the gaming ball has passed through the passing gate 41 provided in the gaming area 10, a normal drawing game by the normal symbol display 20 is started. If a predetermined time, which is the normal symbol fluctuation time, elapses after starting the fluctuation of the normal symbol, and the normal symbol other than the normal symbol per symbol is stopped and displayed, the fluctuation display result of the normal symbol is "out of normal symbol". Become. If a specific normal symbol (design per normal symbol) is stopped and displayed, the variable display result of the normal symbol becomes "per normal symbol", and the expansion / opening control (tilted control) of the normal variable winning ball device 6B is performed. Normal open control is performed to return to the vertical position over time.

After the first start condition is satisfied due to the game ball winning the first start winning opening, for example, the first start condition is satisfied due to the end of the previous special figure game or the jackpot game state. , The special symbol game by the first special symbol display 4A is started. In addition, after the second start condition is satisfied due to the game ball winning the second start winning opening, for example, the second start condition is satisfied due to the end of the previous special figure game or the jackpot game state. Therefore, the special symbol game by the second special symbol display 4B is started.

In the special symbol game, after the variable display of the special symbol is started, the confirmed special symbol (special symbol display result) is derived and displayed when the variable display time elapses. At this time, if a specific special symbol (big hit symbol) is stopped and displayed, it becomes a "big hit" as a specific display result, and if a special symbol different from the big hit symbol is stopped and displayed, it becomes "missing". After the variable display result in the special figure game becomes a "big hit", the game is controlled to a big hit game state as a specific game state in which a round advantageous to the player (also referred to as a "round game") is executed a predetermined number of times.

In the big hit game state, the big winning door of the special variable winning ball device 7 is a period until a predetermined upper limit time (for example, 29 seconds or 0.1 seconds) elapses or a predetermined number (for example, 9) of winning balls. The big prize opening will be open until the occurrence of. As a result, a round is executed in which the special variable winning ball device 7 is set to the first state (open state) which is advantageous for the player.

The large winning opening door that opens the large winning opening during the execution of the round catches the game ball falling on the surface of the game board 2, and then closes the large winning opening, so that the special variable winning ball device can be used. 7 is changed to a second state (closed state) which is disadvantageous to the player, and one round is completed. The round, which is the opening cycle of the big winning opening, can be repeatedly executed until the number of executions reaches a predetermined upper limit (for example, "16").

In the effect symbol display areas 5L, 5C, and 5R of the effect display device 5, the variable display of the effect symbol is started in response to the start of the special figure game. Then, in the period from the start of the variable display of the effect symbol to the end of the variable display, the variable display state of the effect symbol may be in a predetermined reach state. The reach state is a display in which the effect symbols that have not been stopped and displayed when the effect symbols that have been stopped and displayed in the display area of the effect display device 5 form a part of the jackpot combination continue to change. It is a state, or a display state in which all or part of the effect symbols are changed in synchronization while forming all or part of the jackpot combination.

As a definite special symbol in the special figure game, of the multiple types of jackpot combinations, the definite effect symbol that is a predetermined normal jackpot combination (also referred to as "non-probability variable jackpot combination") is stopped and displayed, and the variable display result is "non-probable variable jackpot". If it becomes, it is controlled to the big hit state, and after the end, the time reduction control (time reduction control) is performed. By performing the time reduction control, the fluctuation display time (special figure fluctuation time) of the special symbol in the special figure game is shortened as compared with the normal state. In the time saving control, the so-called electric chew support is carried out in which the winning frequency of the normal symbol is increased and the winning frequency of the normal variable winning ball device 6B is increased. In the time saving control, either of the conditions that the special figure game is executed a predetermined number of times (for example, 100 times) after the end of the big hit game state and that the variable display result becomes "big hit" is satisfied first. Sometimes you just have to quit.

As a definite special symbol in the special figure game, of the multiple types of jackpot combinations, the definite effect symbol that is a predetermined probability variation jackpot combination (also referred to as "probability variation jackpot combination") is stopped and displayed, and the variable display result is "probability variation jackpot". If it becomes a big hit, it is controlled to a big hit state, and after the end, probability fluctuation control (probability change control) is performed together with time reduction control. By performing this probability variation control, the probability that the variation display result becomes a "big hit" in each special figure game is improved so as to be higher than in the normal state. In the probabilistic control, when the condition that the fluctuation display result becomes "big hit" after the end of the big hit game state and the control is made to the big hit game state again is satisfied, a predetermined number of times (for example, 100, which is the same as the time reduction number) after the end of the big hit game state is satisfied. When the special figure game of (times) is executed, it is decided that "there is a probability change fall" to end the probability change control in the probability change fall lottery that is executed every time the special figure game is started after the jackpot game state ends. When, etc., it should end.

When the time reduction control is performed, the fluctuation time of the normal symbol (normal symbol fluctuation time) in the normal diagram game is shortened compared to the normal state, and the variation display result of the normal symbol in each normal diagram game is "normal diagram". Control to improve the probability of "hit" compared to the normal state, tilt control time to control the tilt of the movable wing piece in the normal variable winning ball device 6B based on the fact that the fluctuation display result is "hit" It is possible to make it easier for the game ball to pass (enter) the second start winning opening, such as control to make it longer than in the normal state and control to increase the number of tilts compared to the normal state, and the second start condition can be satisfied. Controls (electric chew support control, high open control) that are advantageous to the player by enhancing the performance are performed. This makes it easier to establish the second start condition for executing the special figure game using the second special figure, and the special figure game can be executed frequently, so that the variable display result is "big hit" next. The time until becomes is shortened.

Next, the operation (action) of the pachinko gaming machine 1 in this embodiment will be described. On the main board (not shown), when the power supply from the predetermined power supply board is started, the game control microcomputer (not shown) is started, and the CPU (not shown) performs the game control main process.

In the special symbol process processing, the CPU first determines whether or not there is a first start prize or a second start prize, and if there is a prize, it is for determining a special symbol display result, for determining a jackpot type, and a variation pattern. A start winning process is executed in which random values for determination and the like are extracted and stored (stored) at the highest level of empty entries in the first special figure holding storage device and the second special figure holding storage device.

Further, the CPU determines whether or not to start the special figure game based on the presence / absence of the hold data stored in the first special figure hold storage device and the second special figure hold storage device, and the special figure display result. Based on the numerical data indicating the random value for judgment, it is decided (predetermined) whether or not the variation display result of the special symbol or the effect symbol is a "big hit" before the variation display result is derived and displayed. Executes normal design processing. That is, when the CPU starts the variable display of the special figure game, whether or not to derive and display the jackpot display result as the display result of the variable display based on the random number value stored when the start winning is generated. Execute the process of determining (lottery).

Next, a variation pattern setting process for determining the variation pattern to one of a plurality of types, a special symbol variation process for setting a variation of the special symbol and measuring the elapsed time from the start of the variation of the special symbol, Stops the fluctuation of the special symbol and confirms. Performs the special symbol stop processing to set the stop display (derivation) of the special symbol. When the variable display result is "big hit", the big hit opening pre-processing, the big hit opening processing, the big hit opening post-processing, and the big hit end processing are performed to open and close the big winning opening in the big hit game state.

Next, the operation of the effect control board (not shown) will be described. First, the effect control CPU starts executing the main process when the power is turned on. When a timer interrupt occurs in the main process, command analysis process, effect control process process, and effect random number update process are executed.

In the effect control process process, the hold storage display in the first hold storage display area 5D and the second hold storage display area 5U of the effect display device 5 is updated to the display according to the storage contents of the hold storage buffer. To execute. Next, according to the value of the effect control process flag, the variation pattern specification command reception waiting process for confirming whether or not the variation pattern specification command is received from the game control microcomputer is controlled so that the effect symbol variation is started. Control of the switching timing of each fluctuation state (fluctuation speed) that composes the fluctuation pattern according to the process data set in the effect symbol fluctuation start processing and the production symbol fluctuation start processing, and monitor the end of the fluctuation time. Display control of the effect display device 5, sound output from the speakers 8L and 8R, light emission of the effect LED 9, and drive control of the effect unit (not shown), etc. Controls to derive and display (stop symbol) Performs the effect symbol fluctuation stop process.

In the big hit display process, after the end of the fluctuation time, the effect display device 5 is controlled to display a screen for notifying the occurrence of the big hit. In the processing during the big hit game, control is performed during the big hit game. In the jackpot end effect processing, the effect display device 5 performs display control to notify the player that the jackpot game state has ended.

It is easy to recognize that you are there. If the misalignment has occurred, a predetermined correction process is performed to correct the misalignment.

Further, as shown in FIG. 7, a pair of elevating clamps 320 provided so as to be movable in the front-rear direction by a slide mechanism 340 are provided on both upper side edges of the table 302, and on the upper surface of the table 302, With the game board surface 2a facing upward so that the obstacle nail 200 faces upward, the game board 2 is held between the table 302 by pressing the game board 2 from above the obstacle nail 200, and the game board 2 is held on the table 302. , Can be fixed.

As shown in FIG. 7, the elevating clamp 320 of this embodiment is formed of a substantially U-shaped transparent resin plate having a gap formed in the central portion, and the obstacle nail 200 to be maintained is the obstacle nail 200. The elevating clamp 320 moves sequentially so as to be located directly under the gap, and by pressing the nail close to the obstacle nail 200 to be maintained by the elevating clamp 320 to fix the game board 2, the position shift in maintenance occurs. In addition to preventing this, even if the obstacle nail 200 to be maintained is pressed, the maintenance status of the obstacle nail 200 to be maintained can be visually recognized through the transparent elevating clamp 320.

As shown in FIG. 6, the maintenance tool 400 is composed of a rod-shaped portion 401 made of a metal rod-shaped member having a diameter of about 6 mm, and a holding portion 403 attached to the lower end side of the rod-shaped portion 401 and made of a metal material. It is mainly configured so that the upper end of the rod-shaped portion 401 can be interchangeably attached to the head 317, and there are a plurality of types having different shapes of the sandwiching portion 403 (see FIG. 11), which are shown in FIG. As described above, a predetermined number is prepared in advance so as to be replaceable around the base 310.

In the obstacle nail maintenance inspection device 300 of this embodiment, the clamp control pattern A shown in FIG. 9A and the clamp control pattern shown in FIG. 9B are used to hold and fix the game board 2 by the elevating clamp 320. B is set, and the control unit 300'controls the position and pressing pressure of the elevating clamp 320 based on the set clamp control pattern.

In the clamp control pattern A, as shown in FIG. 9A, the obstacle nail 200 to be maintained is positioned in a substantially U-shaped gap of one elevating clamp 320, and the position of the other elevating clamp 320 is set back and forth. This is a clamp control pattern that is arranged symmetrically with respect to the center position in the direction and controls the gaming board 2 to be pressed, held, and fixed with a lower pressure (smaller force) than the clamp control pattern B.

As shown in FIG. 9B, the clamp control pattern B has a higher pressure (larger) than that of the clamp control pattern A on the game board 2 in a state where both elevating clamps 320 are arranged at the center positions in the front-rear direction. It is a clamp control pattern that controls to hold and fix by pressing with force). In the clamp control pattern B, when the elevating clamp 320 is arranged at the center position in the front-rear direction, if the obstacle nail 200 to be maintained is covered with the elevating clamp 320, the obstacle nail 200 to be maintained is covered. Moves the position of the elevating clamp 320 to a position where the elevating clamp 320 is not covered with the elevating clamp 320, and holds and fixes the game board 2.

In this embodiment, each of these clamp control patterns is selected according to the maintenance content, as shown in FIG. Specifically, when the obstacle nails 200 to be maintained are designated nails 204 to 208, the clamp control pattern B is selected (see FIG. 9B), and the obstacle nails 200 to be maintained are designated nails 204 to 208. When the obstacle nail 200 is other than 208, the clamp control pattern A is selected (see FIG. 9A).

Further, when the tool type used in the maintenance is the maintenance tool 400 of the tool type A used for servicing only one obstacle nail 200 having a cylindrical shape, the clamp control pattern A is selected. In the case of the maintenance tool 400 of the tool types B and C used for servicing a plurality of obstacle nails 200 at the same time, the clamp control pattern B is selected.

Further, when the fluctuation amount (maintenance amount) in maintenance is equal to or more than a preset predetermined threshold value, the clamp control pattern B is selected, and when the fluctuation amount (maintenance amount) is less than the threshold value, the clamp control is performed. Pattern A is selected. In principle, the relationship between these maintenance contents and the clamp control pattern is given priority over the clamp control pattern B. That is, when the maintenance content includes the maintenance content corresponding to the clamp control pattern B, for example, even if the maintenance content is other than the designated nails 204 to 208 and the maintenance content is based on the tool type A, the fluctuation amount When the (maintenance amount) is equal to or greater than the threshold value, the clamp control pattern B is selected.

As described above, in this embodiment, there are differences in the types of obstacle nails 200 to be maintained, differences in the types of maintenance tools 400 used for maintenance, and differences in the amount of fluctuation (maintenance amount) in maintenance. Since different clamp controls are performed according to the above, the game board 2 can be suitably held, and a plurality of types of maintenance having different maintenance contents can be appropriately performed. In the inspection using the inspection tool, the holding and fixing by the clamp control pattern of the immediately preceding maintenance are maintained.

Next, the maintenance tool 400 used for maintenance in the obstacle nail maintenance inspection device 300 will be described. As shown in FIG. 11, there are a plurality of types of maintenance tools 400 having different shapes of the holding portions 403. Specifically, the maintenance tool 400 is roughly classified into three types according to the number of obstacle nails 200 to be maintained at the same time. Tool type A is a maintenance tool 400 used for servicing only one obstacle nail 200, and tool type B is a maintenance tool used for servicing two obstacle nails 200 at the same time. 400, and the tool type C is a maintenance tool 400 used for simultaneously servicing three obstacle nails 200.

Further, as illustrated in A-1 to A-4 of FIG. 11, there are a plurality of types of maintenance tools 400 of the tool type A depending on the shape of the tip portion, the size of the opening, and the like. These tool types A are mainly used for maintenance of guide nails 201L and 201R called continuous nails. Further, as illustrated in B-1 to B-4 of FIG. 11, the maintenance tool 400 of the tool type B also has the width, shape, and pinching of the groove through which the obstacle nail 200 formed in the pinching portion 403 is inserted. There are a plurality of types depending on the thickness of the portion 403 and the like. These tool types B are mainly used for maintenance of obstacle nails 200 and the like facing a winning opening called a life nail such as designated nails 204 to 208. The maintenance tool 400 of the tool type C is a maintenance tool 400 mainly used for maintenance of the designated nail 205. In this embodiment, the embodiment in which the tool type C is set to two types is illustrated, but the present invention is not limited to this, and the tool type C is also an obstacle formed in the holding portion 403. Various types may be provided depending on the width and shape of the groove through which the nail 200 is inserted, the thickness of the holding portion 403, and the like.

The obstacle nail maintenance inspection device 300 of this embodiment was placed on the game board surface 2a by using the maintenance tool 400 in the process S5 in the manufacturing process of the game board 2 described later by exchanging the maintenance tool 400. Of the plurality of obstacle nails 200, the first maintenance is to maintain the obstacle nail 200 in which an abnormality is detected in the process S4 based on the first maintenance data, and the designated nails 204 to 208 are to be maintained based on the second maintenance data in the process S7. It is said that any of the second maintenance to be carried out is feasible.

Here, the first maintenance for the obstacle nail 200 other than the designated nails 204 to 208 performed by the obstacle nail maintenance inspection device 300 will be described. As described above, the first maintenance is the maintenance performed for the obstacle nail 200 in which the position abnormality is detected in the step S4, and the defect (NG) is performed by using the maintenance tool 400 of the above-mentioned tool type A. Each of the obstacle nails 200 determined to be the above is executed independently. Specifically, the content of the defect (NG) will be described by taking as an example a case where the arrangement position coordinates of the head portion 200b of the obstacle nail 200 are not within the appropriate range because the body portion 200a is not tilted at an appropriate angle. The obstacle nail is placed in the tubular shape of the maintenance tool 400 of tool type A and tool number A-2 so that the arrangement position coordinates of the head 200b of the defective (NG) obstacle nail 200 are within an appropriate range. By tilting the maintenance tool 400 with the 200 stored, the obstacle nail 200 can be maintained at an appropriate angle, or the head 200b can be fitted to the lower end of the maintenance tool 400 of tool number A-3. By moving the maintenance tool 400 together, the arrangement position coordinates of the head 200b are set within an appropriate range.

Next, the contents of the maintenance (second maintenance; step S7) for the designated nails 204 to 208 will be described with reference to FIG. In the following, the second maintenance content of the designated nail 204 will be described as an example, and the same applies to the second maintenance content of the other designated nails 205 to 208. However, the separation dimension between the nails may be different between the designated nail 204 and the designated nails 205 to 208. As shown in FIG. 8, the left and right obstacle nails 200, which are designated nails 204, are tilted upward by about 4 degrees with respect to the Z-axis direction orthogonal to the game board surface 2a in a state of being driven by the nail gun 16. ing. Further, at the set position, the separation dimension L2 on the base end side and the separation dimension L3 on the head 200b side of the body portion 200a of each of the left and right obstacle nails 200 are the same about 10.5 mm (L2 = about 10.5 mm, L3). = About 10.5 mm). That is, the left and right obstacle nails 200 are driven so that the body portions 200a of the left and right obstacle nails 200 are substantially parallel to each other. In the second maintenance, the distance between the left and right obstacle nails 200 of the designated nail 204 is gradually widened from the base side toward the head 200b side, and the head 200b is placed at the designated position where the separation dimension L3 is about 11.5 mm. 2 Performed based on maintenance data.

The obstacle nail maintenance inspection device 300 operates the holding portion 403 of the maintenance arm 301 by a drive source (not shown) based on the second maintenance data received from the management computer 500 to maintain the designated nail 204. The second maintenance data is based on the humidity / temperature data obtained from the hygrometer / thermometer described above by the management computer 500 when servicing the designated nail 204 of the game board 2, for example, the game board 2. When the material is a veneer plate, the water content of the veneer plate is calculated, and the operation pattern data for the veneer plate for operating the holding portion 403 of the maintenance arm 301 based on the water content is included. In this way, since the designated nail 204 of the plywood game board 2 can be maintained according to the change in the indoor environment (humidity / temperature) in the factory, it is possible to prevent the veneer plate from being damaged during the maintenance work of the designated nail 204. , Maintenance accuracy is improved.

Further, as the maintenance tool 400, a plurality of types of maintenance tools 400 having dimensions and shapes according to the type of the game board 2 and the target obstacle nail 200 are prepared, and the obstacle nail 200 to be maintained is provided. It is said that it can be replaced accordingly. It should be noted that such selection and replacement operation of the maintenance tool 400 is included in the second maintenance data, and the maintenance arm 301 automatically performs the operation according to the obstacle nail 200 to be maintained. It may be replaced manually by a person.

The obstacle nail maintenance inspection device 300 drives the maintenance arm 301 in a predetermined operation pattern based on the received second maintenance data, and moves the holding portion 403 from the initial drive position to the placement position of the designated nail 204 to be maintained. , The pinching portion 403 is moved above the game board 2 so as not to come into contact with the obstacle nail 200. The position of the designated nail 204 can be specified from the coordinate data of the designated nail 204, and the second maintenance data includes the coordinate data of the position where the maintenance tool 400 is placed and the data such as the moving direction and the angle. It is included, and by operating the maintenance arm 301 based on the second maintenance data, maintenance by accurate operation can be performed.

Next, as shown in FIG. 8A, the sandwiching portion 403 is lowered to the front side of the designated nail 204 so that the openings of the concave grooves 411L and 411R face the designated nail 204 side. Then, as shown in the direction of the white arrow in FIG. 8A, the sandwiching portion 403 is moved backward, and the body portions 200a of the left and right obstacle nails 200 are fitted into the concave grooves 411L and 411R, respectively. Place in position. As a result, the body portions 200a of the left and right obstacle nails 200 are sandwiched by the concave grooves 411L and 411R. At this predetermined position, the rod-shaped portion 401 is tilted upward by a predetermined angle (about 4 degrees) with respect to the Z axis (perpendicular line) at this predetermined position.

At the predetermined position, as shown in FIG. 8A, the lower surface of the sandwiching portion 403 is separated from the game board surface 2a, and the separation dimension L4 is about 2.5 mm (L10 = 2.5 mm). That is, the pinching portion 403 is arranged at a position on the body portion 200a on the base side closer to the game board surface 2a than the head portion 200b. Further, the rod-shaped portion 401 is arranged in a state of being tilted upward by a predetermined angle θ1 (θ1 = 4 degrees) with respect to the Z axis (perpendicular line) so as to be parallel to the body portion 200a of the obstacle nail 200. Further, the vertical dimension L5 of the pinching portion 403 is shorter than the length L1 from the game board surface 2a to the head 200b of the obstacle nail 200 (L5 <L1), and the pinching portion 403 and the head of each obstacle nail 200. Since it is separated from the 200b, the holding portion 403 can be slid toward the head 200b side.

Next, as shown in FIG. 8B, the pinching portion 403 is divided into a plurality of times while swinging the rod-shaped portion 401 left and right at a predetermined angle with reference to the center position CP in the left-right direction on the lower surface of the pinching portion 403. Move to. Specifically, the pinching portion 403 is tilted by tilting the rod-shaped portion 401 toward the right side by a predetermined angle θ2 (θ2 = about 13.15 degrees) with respect to the center position CP in the left-right direction on the lower surface of the pinching portion 403. The operation is stopped for a predetermined period (for example, about 0.6 seconds) in the state. Next, the sandwiching portion 403 is moved by the first movement amount (for example, about 0.35 mm) from the first position in a direction inclined upward by about 4 degrees with respect to the Z-axis direction, and is arranged at the second position. As shown in 8 (B), the sandwiching portion 403 is tilted by a predetermined angle θ2 (θ2 = about 13.15 degrees) with the rod-shaped portion 401 facing the left side with respect to the central position CP, and then returned to the Z axis, and then further. Tilt a predetermined angle θ3 (θ3 = about 12.25 degrees) toward the left side, and stop the operation for a predetermined period (for example, about 0.6 seconds) in the tilted state.

In this way, when the pinching portion 403 is tilted in the left-right direction with respect to the central position CP, the obstruction nail 200 on the direction of swinging the rod-shaped portion 401 has a larger bending angle than the obstruction nail 200 on the other side. By repeating the process a plurality of times, the distance between the obstacle nails 200 of the designated nails 204 is gradually widened from the base side to the head 200b side. By such maintenance, the obstacle nail 200 constituting the designated nail 204 is arranged at a designated position where the separation dimension is a predetermined dimension (about 11.5 mm).

Next, the first inspection and the second inspection performed by the obstacle nail maintenance inspection device 300 will be described below. In this embodiment, as the inspection tools used for the inspection in the obstacle nail maintenance inspection device 300, as shown in FIG. 12, the inspection tool 600 of the tool number D-1 and the inspection tool of the tool number D-2 are used. Two inspection tools of the tool 620 can be used, the inspection tool 600 is used in the first inspection (process S6), and the inspection tool 620 is used in the second inspection (process S8). ..

First, the first inspection will be described. In the first inspection, it is determined whether or not the head 200b of the obstacle nail 200 for which the first maintenance has been performed is arranged within the allowable range of the designated position. In this first inspection, in addition to whether or not the head 200b of the first maintained obstacle nail 200 is arranged within the allowable range of the designated position, the bending condition of the body portion 200a of the obstacle nail 200 is normal. It also inspects (determines) whether or not it is.

In this first inspection, the obstacle nail maintenance inspection device 300 first replaces the maintenance tool 400 with the inspection tool 600 shown in FIG. The inspection tool 600 is mainly composed of a rod-shaped portion 601 made of a metal rod-shaped member having a diameter of about 6 mm, and a measuring portion 602 attached to the lower end side of the rod-shaped portion 601 and made of a metal material. The measuring unit 602 has a base portion 602a fixedly installed on the lower end side of the rod-shaped portion 601 and a moving portion 602b provided so as to be movable relative to the base portion 602a. As shown in FIG. 15, the moving portion 602b has a plate-shaped piece extending forward from the lower end of the rod-shaped portion 601, and the tip of the plate-shaped piece has a first contact side 602L and the first contact portion 602L. A substantially V-shaped notch 603 in a plan view having a second contact side 602R formed so as to intersect the contact side 602L is formed. The measuring unit 602 configured in this way can measure the shearing force on the base 602a and the direction in which the shearing force is applied by the force sensor F by moving the moving unit 602b with respect to the base 602a in the XYZ axis direction. .. The valley portion of the substantially V-shaped notch portion 603 is the base point RP.

Next, as shown in FIG. 14, using the inspection tool 600, the XY-axis directions at a plurality of locations (in this embodiment, the inspection points P1 and P2) of the body portion 200a of the obstacle nail 200 in the Z-axis direction. Measure the position (coordinates) of. Then, a calculation unit (not shown) provided on the base portion 602a detects the bending condition of the obstacle nail 200 based on the position data (coordinate data). Specifically, as shown in FIG. 15A, the base point RP of the inspection tool 600 is arranged at the inspection start position corresponding to each of the inspection points P1 and P2. Subsequently, as shown in FIG. 15B, the inspection tool 600 is moved in the XY axis direction (horizontal direction) so that the base point RP is arranged at the designated position. That is, if the head portion 200b of the obstacle nail 200 is arranged within the allowable range of the designated position by the first maintenance, the first contact side 602L and the second contact side 602R do not contact the body portion 200a and the base point RP is set. It can be moved from the inspection start position to the specified position.

However, when the obstacle nail 200 is not within the allowable range of the designated position, the obstacle nail 200 comes into contact with either one of the first contact side 602L and the second contact side 602R (for example, the second contact side 602R). , A pressure acts in the direction of the dotted arrow in FIG. 15B, whereby the moving portion 602b moves with respect to the base portion 602a, so that the shearing force with respect to the base portion 602a and the direction in which the shearing force is applied are measured. The obstacle nail maintenance inspection device 300 guides the inspection tool 600 in the direction in which the shear force and its direction decrease (the direction in which the minimum value is obtained). The above operation is repeated, and as shown in FIG. 15C, the base point RP of the inspection tool 600 is placed at a position where it abuts on the obstacle nail 200. The obstacle nail maintenance inspection device 300 transfers the above-mentioned first inspection result information including the movement amount and the movement direction of the base point RP of the inspection tool 600 to the position where the base point RP abuts on the obstacle nail 200 to the management computer 500. Send.

The management computer 500 (CPU502) that has received the second inspection result information specifies the amount of deviation of each of the inspection points P1 and P2 with respect to the designated position in the XY axis direction based on the second inspection result information. That is, when the management computer 500 (CPU502) contacts the first contact side 602L or the second contact side 602R while the base point RP of the first contact side 602L and the second contact side 602R is moving toward the designated position. The degree of bending of the body portion 200a is specified based on the amount of deviation from the designated position at each of the inspection points P1 and P2 due to the load applied to the body.

Further, by specifying the bending condition of the obstacle nail 200 from the amount of deviation in the XY axis direction with respect to the designated position of the body portion 200a at each inspection points P1 and P2, the length of the head portion 200b of the obstacle nail 200 from the game board surface 2a. The dimensions can be specified. That is, even if the head portion 200b does not deviate from the set position in the XY axis direction, it is possible to grasp a problem that the body portion 200a is bent, so that the planting state of the obstacle nail 200 can be inspected with high accuracy. Then, if the obstacle nail 200 is not within the allowable range of the designated position in the first inspection, or if it is determined that there is a problem in the bending condition or the like, correction maintenance data (refirst maintenance data) is created. Then, the obstacle nail 200 is redeveloped (see FIG. 21). In this embodiment, in the first inspection, the management computer 500 (CPU502) is moving the base point RP between the first contact side 602L and the second contact side 602R toward the designated position, and the first contact side 602L. Alternatively, the present invention exemplifies a mode in which the degree of bending of the body portion 200a is specified based on the amount of deviation from the designated position at each inspection point P1 and P2 due to the load applied when the second contact side 602R is contacted. The deviation from the designated position at each inspection point P1 or P2 is based on the amount of movement and the movement direction (movement locus) that the base point RP has moved from the inspection start position to the position where it abuts on the obstacle nail 200. The amount may be measured to specify the degree of bending of the body portion 200a.

Further, the present embodiment exemplifies a mode in which the management computer 500 (CPU502) executes the determination of the first inspection based on the second inspection result information, but the present invention is not limited thereto. , These determinations are executed by the control unit 300'of the fault nail maintenance inspection device 300, and only when there is a defect in the inspection, the second inspection result information is transmitted to the management computer 500 (CPU502) to correct it. Maintenance data (refirst maintenance data) may be acquired. Further, in the present embodiment, the embodiment in which the first inspection is performed using the inspection tool 600 is exemplified, but the present invention is not limited to this, and the first inspection is performed by the camera in the obstacle nail maintenance inspection device 300. You may do it.

Next, the second inspection will be described. In the second inspection, the distance between the designated nails 204 to 208 where the second maintenance is performed is different from the first position where the height position from the game board surface 2a is different. At the second position (see FIG. 19), it is determined (inspected) whether or not the dimensions are appropriate. In this second inspection, the obstacle nail maintenance inspection device 300 first replaces the maintenance tool 400 used for the second maintenance with the inspection tool 620 shown in FIG. In this embodiment, the second inspection is performed in the order of the first position → the second position in each of the designated nails 204 to 208, but the second inspection may be performed in the order of the second position → the first position.

FIG. 16 is a six-view view showing an inspection tool 630 swingably mounted on the tip of the inspection tool 620. As shown in FIG. 16, the inspection tool 630 of this embodiment has an L-shaped metal plate having a predetermined thickness, and has a mounting portion 630a made of a vertically long rectangular metal plate and the mounting portion 630a. It is composed of an inspection part 630b made of a metal plate having a width wider than the part 630a, the inspection part 630b forming the first surface, and the mounting part 630a with respect to the first surface which is the inspection part 630b. It has a second surface that is shaped to bend at a right angle. In this embodiment, the angle formed by the mounting portion 630a and the inspection portion 630b is set to a right angle so that the inspection portion 630b can be arranged in a region on the board surface where the distance between the mounting portions 630a and the inspection portion 630b is narrow. The angle formed by the inspection portion 630b (first surface portion) and the mounting portion 630a (second surface portion) is not limited to an angle other than a right angle, that is, an angle smaller than 90 degrees or larger than 90 degrees. The angles may be used, and these angles may be determined according to the state of the designated nail to be inspected.

Two insertion holes 631 for screws 627 are formed in the upper part of the mounting part 630a on the side opposite to the inspection part 630b side in the longitudinal direction, and between the upper and lower two insertion holes 631. A swinging shaft hole 632 having a diameter smaller than that of the insertion hole 631 and capable of swinging the swinging shaft 622 for swinging the inspection tool 630 is formed. The swing shaft hole 632 has a diameter almost the same as the diameter of the swing shaft 622, whereas the insertion hole 631 has a diameter slightly larger than the diameter of the screw 627 to be inserted. As will be described later, when the screw 627 is inserted into the insertion hole 631, the inserted screw 627 does not hinder the swing of the inspection tool 630 (FIG. 17 (C)). )reference).

The inspection unit 630b is formed by bending forward at a right angle from the lower end of the mounting portion 630a, and the mounting portion 630a and the inspection portion 630b constitute an inspection tool 630 having a substantially L-shaped side view. Further, at a position close to the left and right sides of the mounting portion 630a on the rear side of the inspection portion 630b, a groove-shaped notch 634 extending forward is formed so as to be parallel to each other. It should be noted that these notch portions 634 are folded when the mounting portion 630a and the inspection portion 630b are formed by bending on the inspection tool 630 whose external dimensions have been determined in advance by polishing or the like in the manufacture of the inspection tool 630. The present invention is not limited to this, although it is formed to prevent the inspection portion 630b from bending due to bending and changing the width dimension of the inspection portion 630b (particularly, the fourth region). The shape may not have these notches 634.

As shown in FIG. 16, the inspection portion 630b has a substantially trapezoidal shape in which the front side (tip side) is small and the rear side (mounting portion 630a side) is large, and the front side (tip side). Since the corner portion of the above is a notch portion 635, the inspection portion 630b is guided by the notch portion 635 when the inspection portion 630b is inserted between the nails, as will be described later. There is. Further, on the left and right side surfaces of the inspection portion 630b, a first step portion 636 and a second step portion 637 that gradually bulge outward toward the rear are provided, and the first step portion is formed from the rear end of the notch portion 635. The left-right width dimension up to the step portion 636, the left-right width dimension from the first step portion 636 to the second step portion 637, and the left-right width dimension from the second step portion 637 to the rear end are different width dimensions. ..

Specifically, as shown in FIG. 18, the inspection portion 630b corresponding to the designated nail 204 has a left-right width dimension of 11.04 mm from the rear end of the cutout portion 635 to the first step portion 636. Further, the left-right width dimension from the rear end of the first step portion 636 to the second step portion 637 is 11.90 mm, and the left-right width dimension from the rear end of the second step portion 637 to the rear end of the inspection section 630b is 12. It is set to .10 mm, and the change in width in each step portion is larger in the first step portion 636 than in the second step portion 637. That is, the region from the tip of the inspection portion 630b to the rear end of the notch portion 635 is the first region having a width dimension of less than 11.04 mm, and the region from the rear end of the notch portion 635 to the first step portion 636 is 11. The region from the rear end of the first step portion 636 to the second step portion 637, which has a width dimension of 04 mm, is inspected from the rear end of the third region, the second step portion 637, which has a width dimension of 11.90 mm. The region up to the rear end of the portion 630b is a fourth region having a width dimension of 12.10 mm. In this embodiment, as shown in FIG. 18, since the inspection unit 630b is inserted between the nails of the designated nails 204 to 208 to perform the second inspection, the entire inspection unit 630b is performed in the second inspection. The shape of the rear end corner is rounded so that the rear end corner of the inspection unit 630b will not get caught between the nails and cannot be pulled out if it accidentally passes between the nails. However, the present invention is not limited to this, and the shape of the rear end corner portion may not be rounded, or may be a notch shape as on the front end side.

Further, in this embodiment, as described above, the designated nail 204 corresponding to the first starting winning opening has an appropriate dimension (separation dimension L3) of 12.0 mm at the first position, and the designated nail corresponding to the general winning opening 60. For 205, the appropriate dimension of the first position (separation dimension L3) is 11.4 mm, and for the designated nail 206 corresponding to the gate 41, the appropriate dimension of the first position (separation dimension L3) is 12.8 mm, and the designation corresponding to the windmill 61. For the nail 207, the appropriate dimension (separation dimension L3) of the first position is 11.5 mm, and for the designated nail 208 corresponding to the warp passage 62, the appropriate dimension (separation dimension L3) of the first position is 11.1 mm. Therefore, in addition to the inspection tool 630 corresponding to the appropriate dimension of 12.0 mm illustrated in FIG. 18, inspection tools corresponding to 11.1 mm, 11.4 mm, 11.5 mm, and 12.8 mm are manufactured, and the manufacturing thereof is performed. A total of five types of inspection tools are prepared in advance so that they can be replaced, including four types of inspection tools that are swingably mounted on the inspection tools.

As shown in FIG. 17, the inspection tool 630 is attached to a mounting tool 621 connected to a head 317 that can be attached to and detached from the maintenance arm 301 in a state of being sandwiched between the mounting tool 621 and the fixing plate 625. As shown in FIG. 17B, the mounting tool 621 has a swinging shaft 622 that is inserted into the swinging shaft hole 632 of the inspection tool 630, and has a screw hole 612 through which a screw 627 can be inserted. It has a mounted mounting surface that is formed. In this embodiment, the embodiment in which the swing shaft 622 is projected and formed on the mounting tool 621 is illustrated. For example, the swing shaft 622 can be used as a separate member of a single unit, and the swing shaft of the single unit can be inserted. A shaft hole may be provided on the mounting surface, and a single swing shaft may be inserted into the shaft hole to form the swing shaft.

Further, the fixing plate 625 has a recess 628 on one surface thereof, which is 0.2 mm larger than the width dimension of the inspection tool 630 so that the upper end portion of the inspection tool 630 can be accommodated. The recess 628 is formed with an insertion hole 629a through which the swing shaft 622 can be inserted and a screw receiving hole 629bb having a thread so as to serve as a receiving portion for the screw 627. To attach the inspection tool 630 to the mounting tool 621, first, the swinging shaft hole 632 of the inspection tool 630 is inserted through the swinging shaft 622 of the mounting surface and arranged, and the fixing plate 625 is mounted from the rear thereof. The swing shaft 622 is inserted into the insertion hole 629a so that the inspection tool 630 is housed in the recess 628 of the 625.

Then, the screw 627 is inserted from the front side of the mounting tool 621 and screwed. At this time, as shown in FIG. 17 (C), the inspection tool 630 sandwiched between the mounting surface of the mounting tool 621 and the fixing plate 625 is screwed with a force that does not make it impossible to swing. A gap of about 0.1 mm is formed between the side surface of the inspection tool 630 and the inner surface of the side wall 626 of the recess 628 of the fixing plate 625, and the side surface of the inspection tool 630 abuts on the inner surface of the side wall 626. As shown in the range, specifically, FIG. 17A, the inspection tool 630 can swing within a range of ± 1.21 mm at the tip position of the inspection unit 630b. The size of the swinging range of these inspection tools 630 is increased by increasing the gap between the side surface of the inspection tool 630 and the inner surface of the side wall 626 of the recess 628 of the fixing plate 625. By reducing the gap, the swinging range is also reduced. That is, the range in which the inspection tool 630 swings can be changed (adjusted) by changing the size of the gap. In this embodiment, these inspection tools 630 need to be inspected in a state where the inspection unit 630b is parallel to the board surface, so that the mounting portion 630a is orthogonal to the game board surface 2a. Since these inspection tools 630 are used in an upright state, they are swingably attached around a reference line CL along a direction orthogonal to the game board surface 2a in the inspection in a used state.

In this way, by making the inspection tool 630 swingable around the reference line CL along the direction orthogonal to the game board surface 2a, the individual of the obstacle nail maintenance inspection device 300 when a plurality of obstacle nail maintenance inspection devices 300 are used. Even if there is some error in the inspection position due to the difference, it is preferable because the inspection tool 630 swings so that the inspection can be smoothly performed without being affected by the error in the inspection position. The present invention is not limited to this, and these inspection tools 630 may not swing.

Here, the second inspection of the present embodiment using the above-mentioned inspection tool 630 will be described in more detail. As described above, the inspection unit 630b is provided with four regions having different width dimensions, and the width dimensions of the first stage portion 636 and the second stage portion 637 gradually increase toward the rear side between these regions. When the inspection unit 630b is inserted into the space between the nails of the obstacle nail 200 (on the line connecting the nail centers), the approach distance (distance from the tip of the inspection unit 630b to the line connecting the nail centers) is formed. ) Is the distance shown in FIG. 17B, the obstacle nail 200 is located at the first step portion 636, the second step portion 637, and the like. Specifically, for example, when the inspection unit 630b is inserted between a pair of obstacle nails 200 having a nail spacing of 11.04 mm, the body portion of the obstacle nail 200 reaches a distance of 1.3 mm. The 200a and the side surface of the inspection unit 630b come into contact with each other. Therefore, when the distance between the nails is less than 11.04 mm, the side surface of the inspection unit 630b abuts on the body portion 200a of the obstacle nail 200 before the approach distance becomes 1.3 mm, and a force (resistance) is applied to the inspection tool 630. Force) will act.

Since the pair of obstacle nails 200 having a nail spacing of 11.04 mm has the same width dimension of the second region of 11.04 mm, the body portion 200a of the obstacle nail 200 and the side surface of the inspection portion 630b come into contact with each other. However, since a large force (resistance force) does not act, it enters the first stage portion 636, and a large force (resistance force) acts on the first stage portion 636. As described above, as shown in FIG. 17B, the first step portion 636 is designed so that the approach distance when the obstacle nail 200 reaches the first step portion 636 is 2.6 mm. ..

Further, when the inspection portion 630b is inserted between the pair of obstacle nails 200 having a nail spacing of 11.90 mm, the width dimension of the third region past the first step portion 636 is also 11.90 mm. Therefore, although the body portion 200a of the obstacle nail 200 and the side surface of the inspection portion 630b are in contact with each other, a large force (resistance force) does not act, so the second step portion 637 is entered, and the second step portion 637 is used. A large force (resistance) acts. As described above, as shown in FIG. 17B, the second step portion 637 is designed so that the approach distance when the obstacle nail 200 reaches the second step portion 637 is 5.1 mm. .. Therefore, when the distance between the nails is 11.04 mm or more and less than 11.90, the side surface of the inspection unit 630b and the obstacle nail 200 before the approach distance becomes 2.6 mm or 2.6 mm. The resistance force due to the contact with the body portion 200a will increase.

Further, when the inspection portion 630b is inserted between the pair of obstacle nails 200 having a nail spacing of 12.10 mm, the width dimension of the fourth region past the second step portion 637 is also 12.10 mm. Therefore, although the body portion 200a of the obstacle nail 200 and the side surface of the inspection portion 630b are in contact with each other, a large force (resistance force) does not act, so that the second step portion 637 is exceeded and the fourth region is entered. .. Therefore, when the distance between the nails is 11.90 mm or more and less than 12.10, the side surface of the inspection unit 630b and the obstacle nail 200 before the approach distance becomes 5.1 mm or 5.1 mm. The resistance force due to the contact with the body portion 200a will increase.

Further, when the inspection section 630b is inserted between a pair of obstacle nails 200 having a nail spacing of 12.10 mm or larger than 12.10 mm, the width dimension of the fourth region past the second step portion 637 is 12. Since it is .10 mm, no large friction or resistance is generated between the body portion 200a of the obstacle nail 200 and the side surface of the inspection portion 630b, and the inspection portion 630b enters the fourth region.

As described above, the approach distance at which a large force acts on the inspection tool 630 differs depending on the distance between the nails. Therefore, the inspection unit 630b is inserted between the nails to be inspected from the tip for inspection. The force acting on the tool 630 is detected by the force sensor F, and the suitability of the separation dimension between the nails is inspected (determined) based on the approach distance when the detected force reaches a preset threshold value. Can be done. The threshold value may be appropriately set from the force (resistance force) acting on the inspection tool 630 in consideration of measurement error, noise, and the like. Specifically, in the second inspection, as shown in FIG. 19A, the height from the game board surface 2a is as high as 14.3 mm from the first position (also referred to as the affiliated position) and the game board surface 2a. An inspection (judgment) is performed on the second position (also called the gauge bar position) whose height is as low as 5.5 mm. As described above, the designated nails 204 to 208 to be inspected for the second inspection are maintained so that the distance between the nails gradually widens toward the head 200b by the second maintenance. The appropriate dimensions of the two positions are different.

In this embodiment, for example, for the designated nail 204, the separation dimension L3, which is an appropriate dimension for the first position, is 12.0 mm as described above, and therefore, as a pass (OK) determination condition at the first position. Must be able to enter the third region with a width dimension of 11.90 mm between the nails and the fourth region with a width dimension of 12.10 mm between the nails, as shown in FIG. 19 (A). It will be good. FIG. 20A shows a determination example in which an inspection (determination) is performed based on the above-mentioned approach distance and the force detected by the force sensor F so as to meet the pass (OK) determination condition of the first position. The appropriate dimension of the first position is 12.0 mm, but an error of about 0.1 mm may be appropriate. Therefore, 11.90 mm or more and less than 12.10 mm are accepted (OK) in this embodiment.

As described above, 2.6 mm shown in FIG. 20A is the approach distance corresponding to the first step portion 636, and 5.1 mm is the approach distance corresponding to the second step portion 637. Therefore, as shown in the graph B of FIG. 20A, when the approach distance at which the force detected by the force sensor F exceeds the threshold value is larger than 2.6 mm and 5.1 mm or less, It may be judged as passed (OK). Further, as shown in Graph A, when the approach distance exceeding the threshold value is 2.6 mm or less, the distance between the nails is smaller than 11.90 mm, so it may be determined that the small NG is smaller than the appropriate size. As shown in Graph C, when the approach distance exceeding the threshold value is larger than 5.1 mm and when the threshold value is not exceeded even if it exceeds 5.1 mm, the distance between the nails is larger than 12.10 mm. It may be determined that the big NG is larger than the appropriate size.

Further, in the present embodiment, the appropriate dimension of the second position is 11.04 mm, which is 0.04 mm larger than the diameter of the game ball so that the game ball having a diameter of 11.00 mm is not caught and stopped between the nails. Since the size is larger than that, as a pass (OK) determination condition at the second position, as shown in FIG. 19B, if the second region having a width dimension of 11.04 mm can be entered between the nails. It will be good.

FIG. 20B shows an example of determination in which an inspection (determination) is performed based on the above-mentioned approach distance and the force detected by the force sensor F so as to meet the pass (OK) determination condition of the second position. As described above, 1.3 mm shown in FIG. 20B is the approach distance corresponding to the tip of the second region, and 2.0 mm is the approach distance corresponding to the substantially central position of the second region. .. Therefore, when the approach distance at which the force detected by the force sensor F exceeds the threshold value is 1.3 mm or less as shown in the graph a of FIG. 20 (B), the separation dimension between the nails is 11. Since it is smaller than 04 mm, it may be determined to be NG. Further, when the approach distance where the force detected by the force sensor F exceeds the threshold value is larger than 1.3 mm, and when the threshold value is not exceeded up to 2.0 mm as shown in the graph b of FIG. 20 (B). It may be determined that the result is acceptable. In this embodiment, the second position exemplifies a mode in which the big NG is not determined, as in the first position, but the present invention is not limited to this, and for example, the first stage portion. If the threshold value is not exceeded up to the approach distance of 2.6 mm corresponding to 636, it may be determined as big NG. Further, in the present embodiment, the control unit 300'of the obstacle nail maintenance inspection device 300 executes each of the above-mentioned determinations as to whether or not the dimensions are appropriate in the second inspection. The management computer 500 may perform these determinations without limitation.

In this embodiment, as described above, the appropriate range is ± 0.1 mm, which is the appropriate dimension. Therefore, as an inspection tool corresponding to the appropriate dimension 11.1 mm of the designated nail 205, the width dimension of the third region is used. Is 11.00 mm, and the width dimension of the fourth region may be 11.20 mm, and as an inspection tool corresponding to the appropriate dimension 11.4 mm of the designated nail 206, the width dimension of the third region is 11.30 mm. There is no problem as long as the width dimension of the fourth region is 11.50 mm, and as an inspection tool corresponding to the appropriate dimension 11.5 mm of the designated nail 207, the width dimension of the third region is 11.40 mm and the fourth region. The width dimension of the third region may be 11.60 mm, and the width dimension of the third region is 12.70 mm and the width dimension of the fourth region is 12 as an inspection tool corresponding to the appropriate dimension 12.8 mm of the designated nail 208. It may be .90 mm.

Next, the flow of the manufacturing process of the pachinko gaming machine 1 will be described focusing on the manufacturing process of the gaming board 2. FIG. 21 is a flowchart showing a rough flow of the manufacturing process of the game board 2. First, a synthetic resin plate (for example, an acrylic plate) or a veneer plate having a predetermined size constituting the game board 2 is cut or drilled by a luter processing device or the like to form a predetermined shape, and then the game board surface 2a is formed. Attach the cell sheet. Next, in order to reduce the positional deviation during driving work of the obstacle nail 200, the wind turbine, etc., a metal gauge plate (not shown) formed according to the gauge data (nail arrangement data) corresponding to the type of the game board 2. A pilot hole is machined on the game board surface 2a (step S1). In this embodiment, the synthetic resin plate (for example, an acrylic plate) charged from the charging port B is assumed to have been previously cut, drilled, and prepared by the manufacturer of the synthetic resin plate. There is.

The game board 2 having a pilot hole formed in the game board surface 2a is a first two-dimensional code marking device 14a or a second two-dimensional code marking device 14b, and is used for gauge data (nail arrangement data) and maintenance operation (maintenance data described later). ) Etc., a gauge number indicating the material of the game board 2, a model code indicating the model of the game board 2, a sub code indicating model auxiliary information such as variations of the same model, a serial number of the game board 2 ( A serial number indicating a unique ID), a production company classification code, barcode information for making data with a conventionally used barcode available, and a type of cell sheet attached to the back of the game board 2. A sticker 15 printed with various codes including an individual two-dimensional code 15a symbolizing a cell number capable of specifying the data, a print date code indicating the date and time of printing, and the like is attached (step S2).

In the production line 12 of this embodiment, it is possible to manufacture game boards 2 having different types, and the nail arrangement and the maintenance contents of the obstacle nail 200 differ depending on the type of the game board 2. Therefore, the various devices provided on the production line 12 read the two-dimensional code 15a printed on the sticker 15 by a reading camera (not shown), and transmit the read serial number and the device number to the management computer 500. .. The management computer 500 that has received the serial number extracts maintenance data corresponding to the serial number, that is, maintenance data corresponding to the game board 2 specified from the serial number from the storage device 505, and is specified from the received device number. The extracted maintenance data is transmitted to the device of the transmission source. Then, in various devices, nailing and maintenance are performed based on the maintenance data received from the management computer 500. In the production line 12, in the nailing (process S3), the first maintenance (process S5), the second maintenance (process S7), etc., the nailing by the nailing machine 16 and the maintenance by the obstacle nail maintenance inspection device 300 are defective. May occur.

In the production line 12, as shown in FIG. 4, the transport device 13 on the supply side and the transport device 13 on the discharge side are arranged in parallel, and each nail gun 16 and each obstacle nail maintenance inspection device 300 are arranged. , The game board 2 is arbitrarily taken out from the transport device 13 on the supply side by the robot arm device described above, and the game board 2 that has been placed or maintained / inspected is placed or maintained / inspected. Since it is not determined in advance which of the plurality of devices will be used for nailing and nail maintenance, the storage device 505 stores the maintenance history of each game board 2 so that each can be returned to. It is possible to identify the device involved in the manufacture of the game board 2. As this maintenance history information is accumulated, it becomes possible to identify which of the various devices has a large number of maintenance defects. Therefore, maintenance work for a plurality of devices installed on the production line 12 can be performed. It is said that it can be done easily.

Further, by storing the maintenance history of each game board 2 in the storage device 505, if a defect of the obstacle nail is found at the final stage of the manufacturing process or after delivery, the maintenance history of the game board 2 is referred to and the game board is concerned. Since it is possible to identify the device involved in the manufacture of 2, that is, the device that may have a defect, the device that may have a defect does not cause maintenance of a new game board 2. As described above, it is possible to take measures at an early stage, such as immediately stopping the drive of the device and performing maintenance work.

Further, in step S2, the sticker 15 on which the two-dimensional code 15a is printed is not exposed from the outside when the sticker 15 is mounted on the pachinko gaming machine 1 (for example, the lower right position in this embodiment). The work of attaching to is performed (see Fig. 2). Further, the seal 15 is for reading provided at a predetermined position of the production line 12 (for example, each nail gun 16, each obstacle nail maintenance inspection device 300, the first nail inspection device 17A, the second nail inspection device 17B). In addition to the two-dimensional code 15a read by the camera, the print date, model code, serial number, gauge number, cell number, barcode information, etc. are converted into alphabets, numbers, symbols, etc. so that the operator can visually check them. It is written as. In the present embodiment, the sticker 15 on which the two-dimensional code 15a is printed is attached to the board surface plate 2A, and the two-dimensional code 15a is read by a reading camera (reading device). It is not limited, and it is very good that a sticker including an IC chip in which the above-mentioned various information is stored can be attached and the information stored in the IC chip can be read by a predetermined reading device.

After the marking work of the two-dimensional code 15a is completed on the board surface plate 2A, a plurality of obstacle nails 200 are driven into the prepared holes in the prepared holes by the nailing machine 16 (process S3). When the nailing machine 16 finishes driving the obstacle nail 200, the nailing machine 16 includes the device number of the nailing machine 16, the reading data of the two-dimensional code 15a read by the reading camera, the temperature and humidity at the time of the work, and the like. The information is transmitted to the management computer 500 as nailing work completion data. Then, the obstacle nail 200 driven into the game board surface 2a by the first nail inspection device 17A is photographed by a plurality of cameras 44 provided in the first nail inspection device 17A, and based on the photographed image data, the obstacle nail 200 is photographed. A nail image inspection is performed to inspect the inclination of each obstacle nail 200 with respect to the Z-axis direction orthogonal to the game board surface 2a (arrangement position coordinates of the head 200b, etc.), the presence or absence of the obstacle nail 200, nail bending, rust, discoloration, etc. ( Step S4). When the inspection is completed, the first nail inspection device 17A transmits the primary inspection result data to the management computer 500 together with the device number of the first nail inspection device 17A and the reading data of the two-dimensional code 15a of the game board 2.

The management computer 500 (CPU502) that has received the primary inspection result data tilts each of the obstacle nails 200 upward by about 4 degrees with respect to the Z-axis direction orthogonal to the game board surface 2a based on the received primary inspection result data. Whether or not it is present is determined from the misalignment direction and the misalignment amount in the XY axis direction with respect to the set position of the head 200b of each obstacle nail 200 specified from the gauge data corresponding to the game board 2. The set position (coordinate position) of the head 200b of each obstacle nail 200 is a position where the head 200b is arranged when the obstacle nail 200 is accurately driven into the prepared hole, and corresponds to the type of the game board 2. It is stored as gauge data in the storage device 505 of the management computer 500.

Further, for each set position, an allowable range (accuracy) is set in consideration of an error in the XY axis direction, and when the head 200b is arranged outside this allowable range, it is determined to be abnormal (defective). At the same time, the direction of deviation from the set position and the amount of deviation are specified. It should be noted that this permissible range can be set to a desired value for each obstacle nail 200 in the management computer 500.

The management computer 500 (CPU502), which has received the primary inspection result data, has out of the allowable range of deviation in the XY axis direction with respect to the set position of the head 200b by the inspection in step S4 among the obstacle nails 200 driven in step S3. For the obstacle nail 200 determined to be present, the first maintenance data for arranging the head 200b of the obstacle nail 200 within the permissible range of the set position is created, and the first maintenance data is received as the primary. It is stored in association with the serial number in the read data of the two-dimensional code 15a included in the inspection result data. The first maintenance data is read data including the serial number 15c from the obstacle nail maintenance inspection device 300 from which the game board 2 to which the seal of the two-dimensional code 15a of the serial number is attached is taken out from the transport device 13. Is transmitted (reply) to the obstacle nail maintenance inspection device 300, and maintenance based on the first maintenance data (first maintenance) is instructed.

In the obstacle nail maintenance inspection device 300, based on the first maintenance data received from the management computer 500, the first maintenance for the obstacle nail 200 in which the abnormality is detected in the process S4 is performed as described above (process S5). .. When the first maintenance is completed, the management computer manages the first maintenance completion data including the reading data of the two-dimensional code 15a and the temperature / humidity information at the time of executing the first maintenance, together with the device number of the obstacle nail maintenance inspection device 300. By transmitting to 500, the management computer 500 is notified that the first maintenance has been completed, and the first maintenance such as the device number and temperature / humidity information of the obstacle nail maintenance inspection device 300 that executed the first maintenance is related. Information is notified and stored.

Then, with respect to the obstacle nails 200 after the first maintenance, whether or not each obstacle nail 200 is tilted upward by about 4 degrees with respect to the Z-axis direction orthogonal to the game board surface 2a is determined with respect to the set position of the head 200b. The first inspection, which is determined based on the misalignment direction in the XY axis direction and the amount of misalignment, is performed as described above, and the inspection result of the first inspection is the device number of the obstacle nail maintenance inspection device 300 and two. It is transmitted to the management computer 500 as the first inspection completion data together with the read data of the dimension code 15a. In this embodiment, these first inspections are performed by the obstacle nail maintenance inspection device 300 that has executed the first maintenance using the inspection tool 600 having the tool number D-1 as described above. The present invention is not limited to this, and these first inspections may be performed by another obstacle nail maintenance inspection device 300 or a second nail inspection device 17B.

The first maintenance (S5) and the first inspection (S6) are repeated until all the heads 200b of the obstacle nail 200 after the first maintenance are arranged within the allowable range of the set position (S6 +; Y). .. However, since the obstacle nail 200 placed within the allowable range by the first maintenance is excluded from the target of the first maintenance again, as the first maintenance is repeatedly executed, the obstacle nail 200 to be maintained The number will gradually decrease.

At the time of these redevelopment, the first maintenance data is created again in the management computer 500 based on the inspection result of the first inspection, and the nail maintenance is executed based on the created first maintenance data. The first maintenance completion data is also transmitted to the management computer 500 every time the first maintenance is repeated. It should be noted that the maintenance contents based on the first maintenance data created by these management computers 500 will be sequentially different maintenance contents according to the number of times (the number of inspection NG times) determined in the first inspection that the maintenance contents are not within the allowable range. It is set. Specifically, when the number of inspection NGs is the first, in principle, the maintenance amount (deformation amount) of the obstacle nail 200 determined to be inspection NG is in the first maintenance before the inspection NG is determined. The maintenance content is changed to a maintenance amount (deformation amount) different from the maintenance amount (deformation amount). When the number of inspection NGs is the second time, in principle, the maintenance content is changed to a tool different from the tool used for the maintenance of the obstacle nail 200 determined to be inspection NG. In addition, when the number of inspections is NG for the third time, in principle, the maintenance content is changed to the obstacle nail maintenance inspection device 300 different from the obstacle nail maintenance inspection device 300 used for the maintenance of the obstacle nail 200 determined to be inspection NG. It is said that. That is, when the first maintenance in which the tool corresponding to the second inspection NG number is changed is executed, the obstacle nail maintenance inspection device 300 that executed the first maintenance is the obstacle nail that executed the first maintenance. The game board 2 having 200 is put into the transfer device 13 by the robot arm device, and the put-in game board 2 is first maintained by another obstacle nail maintenance inspection device 300 taken out from the transfer device 13 by the robot arm device. Is executed. Then, when the inspection is NG in the first inspection after the first maintenance is executed by the other obstacle nail maintenance inspection device 300, the game board 2 is set as the discharge target from the production line. Will be done. Specifically, it is discharged to the outside of the production line by the robot arm device in the obstacle nail maintenance inspection device 300 determined to be the inspection NG.

In this embodiment, in the first maintenance, the maintenance is performed only for the obstacle nail 200 in which the abnormality is detected in the nail image inspection in the step S4, but the present invention is limited to this. Instead, the first maintenance may be performed on all the obstacle nails 200 regardless of the presence or absence of an abnormality. Further, in the present embodiment, a mode in which the first maintenance and the first inspection are performed is illustrated, but the present invention is not limited to this, and for example, the position shift or the like due to the nail image inspection in the step S4 or the like. In the case where there is no obstacle nail 200 of the above, or in the game board 2 of a type that does not require the first maintenance, the first maintenance of the process S5 and the first inspection of the process S6 may be omitted.

If it is determined in the first inspection that there is no obstacle nail 200 for inspection NG (S6 +; N), the game board 2 is returned to the transfer device 13 by the robot arm device. Then, the game board 2 returned to the transfer device 13 is taken out from the transfer device 13 by the robot arm device of another obstacle nail maintenance inspection device 300, and among the plurality of obstacle nails, the game board 2 is previously taken out according to the type of the game board 2. A second maintenance is carried out for the designated nails 204 to 208, which are the designated obstacle nails 200, so that the separation dimension between the designated nails 204 to 208 is an appropriate dimension. That is, the management computer 500 is designated in advance according to the type of the game board 2 among the plurality of obstacle nails for the obstacle nail maintenance inspection device 300 in which the game board 2 for which the first inspection has been completed is taken out from the transfer device 13. For the designated nails 204 to 208, the second maintenance data for setting the separation dimension of the designated nails 204 to 208 to an appropriate dimension is transmitted to instruct the execution of the second maintenance. The fault nail maintenance inspection device 300 that has received the second maintenance data performs the second maintenance for the designated nails 204 to 208 based on the received second maintenance data (process S7).

As described above, in this embodiment, by performing the second maintenance in the obstacle nail maintenance inspection device 300 different from the obstacle nail maintenance inspection device 300 in which the first maintenance is performed, the maintenance accuracy due to the difference in the obstacle nail maintenance inspection device 300 is obtained. However, the present invention is not limited to this, and the first maintenance and the second maintenance may be performed by the same obstacle nail maintenance inspection device 300. ..

In the second maintenance, as described above, the designated nails are gradually widened from the base side to the head 200b side so that the distance between the pair of obstacle nails 200 in each of the designated nails 204 to 208 is the desired appropriate dimension. In addition to the maintenance of 204 to 208, maintenance for changing the inclination angle, inclination direction, arrangement mode of each obstacle nail 200 with other obstacle nails 200, etc. is also included, and maintenance is performed in the first maintenance of step S5. It is done regardless of whether it was done or not. These designated nails 204 to 208 are related to the probability of the game ball entering each winning opening or passing gate 41 related to the addition of the game value, among the plurality of obstacle nails 200 driven into the game board surface 2a. This is an obstacle nail that is likely to affect the base value of the pachinko gaming machine 1 due to slight errors or deviations. Further, the inclination angle, the inclination direction, and the arrangement mode of each obstacle nail 200 with the other obstacle nails 200 change according to the type of the game board 2. It should be noted that this designated nail allows the management computer 500 to designate a desired obstacle nail 200 for each game board 2.

As described above, the first maintenance targets the obstacle nail 200 in which the abnormality is detected in the process S4 among the plurality of obstacle nails 200 driven into the game board surface 2a in the process S3, and the obstacle nail having the abnormality is targeted. While the work of arranging the head 200b of the 200 within the allowable range of the set position is included, the second maintenance targets the pre-designated obstacle nail 200, for example, the designated nails 204 to 208, and the designation thereof. This includes the work of setting the separation dimension between the nails of the obstacle nail 200 to an appropriate dimension. That is, in the second maintenance (process S7), maintenance having a different content from that of the first maintenance (process S5) is performed. Further, the second maintenance is a maintenance that cannot be uniformly or is difficult in the nailing process by the nailing machine 16, and requires delicate work with higher accuracy than the first maintenance, so other obstacle nails. By performing the maintenance work separately from the first maintenance targeting the 200, the maintenance work of the obstacle nail 200 can be efficiently performed. Further, in the game board 2 of a type that does not require the second maintenance for the designated nails 204 to 208, the second maintenance of the step S7 may be omitted.

Then, after performing the second maintenance for the obstacle nails 200 of the designated nails 204 to 208, as described above, the first position is performed by using the inspection tool corresponding to the obstacle nails 200 of the designated nails 204 to 208. A second inspection (step S8) is performed to inspect whether or not the separation dimension between the nails is appropriate for the first position and the second position in the order of the first position to the second position. In the second inspection, as will be described later, redevelopment of the designated nails determined to have inappropriate dimensions (NG determination) is also executed. FIG. 22 is a flow chart showing the contents of the second inspection of S8. In the second inspection, first, the inspection order is determined based on the number of each designated nail. That is, since the designated nails 204 to 208 may have three pairs like the pointed nail 205, the order of the number of these designated nails, that is, the pointed nail 205 (3 pairs) → the pointed nail 204 (1 pair). → The inspection order is determined in the order of pointed nail 206 (1 pair) → pointed nail 207 (1 pair) → pointed nail 208 (1 pair). In this way, by determining the inspection order in descending order of the number of designated nails, if it is determined that the dimensions are inappropriate (NG determination) in the inspection of the second position of the designated nails with the largest number of these, it is immediately determined. Since it is determined to be defective and other designated nails are not inspected, unnecessary inspections and unnecessary replacement of inspection tools can be omitted, but the present invention is not limited to these, and these The inspection order may be appropriately determined in consideration of reducing the number of times the inspection tool is replaced and omitting the inspection time. The inspection order for the pointed nails 205 (3 pairs) may be arbitrarily determined according to, for example, the position or the like.

After the inspection order is determined in S20, the inspection tool corresponding to the pointed nail 205 to be inspected first is replaced (S21). Then, first, as described above for the first position, the inspection unit 630b is inserted from the tip between the nails to perform an inspection (S22), and the inspection results (OK, small NG, big NG) are stored. After that, as described above for the second position, the inspection unit 630b is inserted between the nails from the tip to perform an inspection (S24), and the inspection results (OK, NG) are stored (S25). Then, it is determined whether or not the inspection result is NG (determination of improper dimensions) (S26a). If the inspection result is OK in both the first position and the second position (S26a; N), the process proceeds to S29. When some of the inspection results are NG (S26a; Y), it is further determined whether or not the inspection result of the second position is NG (determination of improper dimensions) (S26b). When the inspection result of the second position is NG (S26b; Y), for example, as shown in FIG. 23, the first position to be inspected first was accidentally determined to have an appropriate dimension. However, since the body part 200a is greatly curved and there is a high possibility that it cannot be corrected to the proper separation dimension even if it is maintained, even if the first position is the proper size, it is not necessary to perform re-inspection or re-maintenance. It is regarded as defective (S50). The defective game board 2 is notified by the obstacle nail maintenance inspection device 300 that it is defective, and is taken out from the obstacle nail maintenance inspection device 300.

In the case where the second inspection is performed in the order of designated nail 205 → designated nail 204 → designated nail 206 → designated nail 207 → designated nail 208 as in this embodiment, for example, in the second inspection of the designated nail 205, the second inspection is performed. If the position is not the proper size, it is judged as defective and notified without performing the second inspection of the designated nail 204 → designated nail 206 → designated nail 207 → designated nail 208, for unnecessary inspection or unnecessary inspection. It is preferable to omit the replacement of tools and the like so that the inspection efficiency of the second inspection can be improved. The present invention is not limited to this, and even if it is determined that the second position is defective, the defect is not immediately determined, but the designated nail 205 → the designated nail 206 → the designated nail 207 → the designated nail 208. 2 After performing all the inspections, it may be determined that the defect is defective and the notification may be made.

On the other hand, when the inspection result of the second position is not NG in the determination of S26b (S26b; N), the inspection result of only the first position is NG, so that the inspection tool is not replaced. The first position is re-examined (S27) and the result of the re-examination is stored (S28). In the present embodiment, the second position is regarded as defective without performing the re-inspection (1), but the present invention is not limited to this, and the second position is also re-inspected (1). Is executed, and if it is determined to be NG again in the re-examination, it may be regarded as a defect.

Then, it is determined whether or not all the designated nails 205, which are designated nails having the same dimensions, have been inspected (S29). When all the designated nails of the same size have not been inspected (S29; N), for example, when there is an uninspected designated nail 205, after specifying the designated nail 205 to be inspected next from the inspection order (S30). ), Return to S22, and inspect another designated nail 205 specified. On the other hand, when all the designated nails having the same dimensions have been inspected (S29; Y), it is determined whether all the designated nails have been inspected (S31). If not all designated nails have been inspected (S31; N), the designated nail to be inspected next, for example, the designated nail 204 if it is next to the designated nail 205, is used based on the inspection order determined in S20. , Identified as the designated nail to be inspected next (S32). The tool is replaced with an inspection tool corresponding to the specified designated nail 204 (S33), and the process returns to S22. If all the designated nails have been inspected (S31; Y), the process proceeds to S34.

By performing the inspection in this way, the pointed nail 205 (3 pairs) → the pointed nail 204 (1 pair) → the pointed nail 206 (1 pair) → the pointed nail 207 (1 pair) → the pointed nail 208 (1 pair) In the order of, for each designated nail, the inspection is performed for each of the first position and the second position using the inspection tool corresponding to each designated nail, and the inspection of the second position is NG. Is determined to be defective immediately without being re-inspected, and if the inspection at the first position is NG, it is re-inspected. Specifically, first, the maintenance tool 400 is replaced with an inspection tool having an inspection tool corresponding to an appropriate dimension of 11.4 mm, and the second inspection is performed for each of the first position and the second position of the designated nail 205. Then, the second inspection is performed on the designated nail 204 by exchanging with an inspection tool having an inspection tool corresponding to the appropriate size 12.0 mm, and then the inspection tool corresponding to the appropriate size 12.8 mm is executed. Perform a second inspection for each of the first and second positions of the designated nail 206, and then replace it with an inspection tool having an inspection tool corresponding to the appropriate size of 11.5 mm. Then, the second inspection is performed for each of the first position and the second position of the designated nail 207, and then finally, the designated nail 208 is replaced with an inspection tool having an inspection tool corresponding to the appropriate size 11.1 mm. The second inspection is performed for each of the first position and the second position of.

In S34, it is determined whether or not there is a designated nail that is determined to be NG again in the re-inspection of the first position based on the stored inspection result. If the designated nail that is determined to be NG again in the re-inspection does not exist, the case where the re-inspection is not executed is included because the inspection in the first position is OK. If there is no designated nail that is determined to be NG again in the re-inspection (S34; N), all the indicated nails 205 to 208 have appropriate dimensions, and the process proceeds to the final inspection of the nail in S9. On the other hand, when the designated nail that is determined to be NG again in the re-inspection exists (S34; Y), the inspection tool is replaced with the maintenance tool 400 of the tool type B, and the designated nail that is determined to be NG again is designated. The nail is redeveloped using the replaced maintenance tool 400 of tool type B (S35). At the time of these redevelopment (second maintenance), the second maintenance data is created again in the management computer 500 based on the inspection result of the previous re-inspection, and based on the created second maintenance data. Nail maintenance is performed, but the present invention is not limited to this, and as these redevelopment (second maintenance), when the same maintenance as the previous maintenance is repeated, or only the previous maintenance and the amount of deformation. In the case of performing almost the same maintenance as the previous maintenance, such as the difference only by changing the above, even if the fault nail maintenance inspection device 300 (control unit 300') creates these second maintenance data. good.

Then, after the re-maintenance is executed, the re-inspected designated nail is re-inspected (2) using the inspection tool corresponding to the re-maintained designated nail (S36). As for this re-inspection, as shown in S20 to S33 of FIG. 22, when there are a plurality of designated nails for re-maintenance, the order is determined, and the first position and the second position are determined according to the determined order. The position inspection may be performed sequentially. If all of the designated nails for redevelopment are judged to be OK in the re-inspection (2) (S37; N), the process proceeds to the final inspection of the nails in S9. Further, when the designated nail for redevelopment is determined to be NG in the inspection at the second position, it is determined to be Y in S37 and S38 and is regarded as defective (S50). Further, regarding the designated nail for redevelopment, when it was determined to be NG in the re-inspection (2), but was not determined to be NG in the inspection at the second position (determined as Y in S37 and determined to be N in S38). Case), that is, when the refurbished designated nail is re-determined as NG only in the first position in the re-inspection (2), the designated nail re-determined as NG only in the first position. Re-maintenance is performed using the maintenance tool 400 of tool type B (S39). In this case, a re-maintenance different from the re-maintenance of S35 (a different amount of deformation, a tool type B but a different maintenance tool is used, etc.) is executed. After that, the designated nails that have been redeveloped are re-inspected (3) using an inspection tool corresponding to the designated nails that have been redeveloped in S35 (S40).

If there is no designated nail that is NG in this re-inspection (3) (S41; N), the process proceeds to the final inspection of the nail in S9. On the other hand, in the re-inspection (3), if there is a designated nail that is NG (S41; Y), even if only the separation dimension at the first position is inappropriate, it is considered defective (S50). The determination of S20 and the determination of S26a, S26b, S34, S37, S38, and S41 may be performed by the control unit 300'of the fault nail maintenance inspection device 300 or by the management computer 500. good.

In the second inspection, when it is determined that the separation dimension between the nails is appropriate for all of the designated nails 204 to 208 (Y in S34, N in S37, N in S41), the second inspection is performed. From the obstacle nail maintenance inspection device 300 that performed the 2 maintenance and the second inspection, along with the device number of the obstacle nail maintenance inspection device 300, the reading data of the two-dimensional code 15a read by the reading camera and the second maintenance and the second inspection. By transmitting the second maintenance completion data including the temperature / humidity information at the time of executing the inspection and the inspection result information of the second inspection (second inspection result information) to the management computer 500, the second maintenance and the second maintenance and the second maintenance are performed to the management computer 500. You will be notified that the second inspection has been completed, and information about the second maintenance such as the device number and temperature / humidity information of the obstacle nail maintenance inspection device 300 that executed the second maintenance, and the inspection result information of the second inspection.

Then, the game board 2 for which the second inspection is completed is thrown into the transport device 13 on the discharge side and conveyed to the second nail inspection device 17B by the robot arm device, and all the obstacle nails in the second nail inspection device 17B. A final nail inspection is performed on the 200 to see if the head 200b of each obstacle nail 200 is in the set position (step S9). In this embodiment, in step S9, the positions of all the obstacle nails 200 of the game board 2 are inspected, but the present invention is not limited to this, and only the designated nails 204 to 208 are used. You may want to inspect. Further, when the game board 2 in which the abnormality is detected in the step S9 is taken out from the production line 12, is re-maintained by an obstacle nail maintenance inspection device 300 or the like different from the production line 12, and the re-maintenance is completed. However, the second maintenance completion data is transmitted from the fault nail maintenance inspection device 300 that has undergone the redevelopment to the management computer 500.

If there is no abnormality in the final inspection of the second nail inspection device 17B, the guide rail 2b and the wind turbine 61 are attached by using the prepared holes formed in the game board surface 2a (step S10). Then, after attaching other gaming members such as a center decorative frame 51, various winning devices, and electronic parts such as a substrate, the pachinko gaming machine 1 is assembled to the gaming machine frame 3 (process S11). Finally, the completed pachinko gaming machine 1 is packed and shipped (process S12).

As described above, according to the present embodiment, the inspection tool 630 is inserted between the nails of the pair of obstacle nails 200 to be inspected for inspection (second inspection), so that the positions of the pair of obstacle nails 200 are inspected respectively. As compared with the case of inspecting the separation dimension between nails, the inspection accuracy can be improved and the inspection time can be significantly shortened. Further, since the inspection (second inspection) can be performed by the obstacle nail maintenance inspection device 300 in which the inspection tool 630 is attached to the maintenance arm 301, the approach direction is compared with the case where these inspections are performed by the inspector. In addition to being able to stabilize (stabilize) the approach angle and enable high-precision inspections, it is also possible to prevent these inspection accuracy from being reduced due to the fatigue of inspectors, and the labor costs required for inspections. Can also be reduced. As a result, it is possible to improve the manufacturing efficiency of the gaming machine and reduce the manufacturing cost of the gaming machine while improving the accuracy of the nail spacing dimension of the gaming machine. With the improvement of the accuracy of the nail spacing dimension of the gaming machine, it is possible to make the gaming performance of the gaming machine uniform, such as the winning rate of the winning opening.

Although examples of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these examples, and any changes or additions that do not deviate from the gist of the present invention are included in the present invention. Will be. For example, in the above embodiment, the embodiments in which the appropriate dimensions between the designated nails 204 to 208 are all different are exemplified, but the present invention is not limited to this, and only a part of the designated nails 204 to 208 is used. , The appropriate dimension of the first position may be the same dimension, or the appropriate dimension of the first position may be the same dimension for all of the designated nails 204 to 208, and thus the appropriate dimension is the same dimension. If there is a designated nail of, the second inspection is performed first from the designated nails with the same number of appropriate dimensions, and if there is a defect in the second position, it is defective at that point. It may be determined that.

Further, in the above embodiment, when the force sensor F is used to allow the inspection unit 630b to enter between the nails from the tip, and the force acting on the inspection tool 630 detected by the force sensor F reaches the threshold value. By determining whether or not the distance between the nails is an appropriate dimension based on the approach distance of the nail, the accuracy of the determination can be improved and an efficient inspection can be performed, but the present invention is limited to this. Instead, for example, the third region of the inspection unit 630b is the approach distance that should be located between the nails, and the inspection unit 630b is made to enter the inspection unit 630b by an approach distance of 3.5 mm. When the force sensor F detects a force equal to or higher than the threshold value, it is determined that the third region is not located between the nails and has an appropriate dimension (determined as small NG), and the force sensor F is determined to be equal to or higher than the threshold value. When the force of is not detected, it may be determined that the third region has an appropriate dimension located between the nails (determined as an appropriate dimension). Further, when the force sensor F does not detect a force equal to or higher than the threshold value in the first approach state, the second approach is further made by allowing the inspection unit 630b to enter the inspection unit 630b by an approach distance of 6.0 mm corresponding to the fourth region. When the force sensor F detects a force equal to or higher than the threshold value in the second approach state, it is determined that the fourth region is not located between the nails, and the force sensor F is determined to have an appropriate dimension. If the force above the threshold value is not detected, it may be determined that the fourth region is located between the nails and the dimension is not appropriate (big NG).

Further, in the above embodiment, an embodiment of performing an inspection (determination) using the force sensor F is exemplified, but the present invention is not limited to this, and for example, a micro that captures an image of the inspection unit 630b. A camera (imaging means) and an image analysis means for analyzing the image captured by the micro camera are provided, and for example, the third region of the inspection unit 630b is the approach distance to be located between the nails, for example, 3. Whether or not the third region is located between the nails from the image captured by the micro camera (imaging means) in the first approach state in which the inspection unit 630b is entered by the approach distance of 5 mm. Is determined by the image analysis means, and if the third region is located between the nails, it is determined to be an appropriate dimension (OK), and if the third region is not located between the nails, specifically, If the first region or the second region is located between the nails, it is determined to be small NG, and further, the inspection unit 630b has an approach distance of 6.0 mm corresponding to the fourth region of the inspection unit 630b. Is set to the second approach state, and if the fourth region is not located between the nails in the second approach state, it is determined that the dimension is appropriate (OK), and the fourth region is located between the nails. In that case, it may be determined as big NG.

Further, in the above-described embodiment, the embodiment in which the re-inspection (S27) is always executed when it is determined in the second inspection of the first position that the dimensions are not appropriate is exemplified, but the present invention is limited to this. Instead of performing these re-examinations, the re-maintenance (S35) may be performed.

Further, in the above-described embodiment, when it is determined in the second inspection of the second position that the dimensions are not appropriate, a mode is illustrated in which a defect is made without performing re-inspection or re-maintenance. Is not limited to this, and may be regarded as a defect when it is determined again that the dimensions are not appropriate by performing re-inspection or re-maintenance as in the case of the first position.

In the above embodiment, the inspection tool 630 of 1 can inspect the first position and the second position, but the present invention is not limited to this, and is dedicated to inspecting the first position. The inspection tool and the dedicated inspection tool for inspecting the second position may be separately provided, and the first position and the second position may be inspected by the individual dedicated inspection tools.

In the above embodiment, the first predetermined dimension and the second predetermined dimension corresponding to the appropriate dimension of the first position are exemplified with the appropriate range of ± 0.1 mm, but the present invention is limited thereto. These appropriate ranges may be values other than ± 0.1 m, for example, 0.05 mm or 0.15 mm, or narrow so that the narrow side is 0.05 mm and the wide side is 0.1 mm. The appropriate range may be different between the side (minus side) and the wide side (+ side). Further, these appropriate ranges may be different for a part or all of the designated nails 204 to 208.

Further, in the above embodiment, the pachinko gaming machine 1 is exemplified as an example of a gaming machine having a board surface provided with nails, but the present invention is not limited to this, and the board surface provided with nails is used. It may be a game machine such as an arrange ball or a slot machine using a game ball. Further, in the above embodiment, the pachinko gaming machine 1 for discharging the gaming ball to the outside is illustrated, but the pachinko gaming machine may be an enclosed type in which the gaming ball is sealed inside so as not to be touchable.

Further, in the above embodiment, as a nail inspection device, the second inspection is executed by the obstacle nail maintenance inspection device 300 capable of performing both the second maintenance and the second inspection for the purpose of shortening the time required for redevelopment. Although the embodiment is exemplified, the present invention is not limited to this, and an obstacle nail inspection device for performing only these second inspections may be provided exclusively. In this case, an inspection tool may be provided. The 620 may be irreplaceably provided on the maintenance arm 301.

Further, in the above embodiment, the shape of the inspection tool 630 is illustrated as an L-shape, but the present invention is not limited to this, and a shape other than the L-shape, for example, the inspection unit 630b. May be T-shaped on both sides of the front and rear surfaces, and the inspection unit on one surface may correspond to the first position and the inspection unit on the other surface may correspond to the second position.

Further, in the above embodiment, the embodiment in which the first inspection is always executed is illustrated, but the present invention is not limited to this, and depending on the model of the gaming machine, the first inspection is not executed. May be good.

Further, in the above embodiment, as the first tool for servicing a plurality of nails, the second maintenance (primary maintenance) using the maintenance tool 400 of the tool type B is performed, and the separation between the nails is performed in the second inspection. When it is determined that the dimensions are not appropriate, re-maintenance using the maintenance tool 400 of tool type B is performed again, but the present invention is not limited to this. In these redevelopments, a second tool for servicing a single nail, for example, a maintenance tool 400 of tool type A, is used for the obstacle nail 200 determined to be not of the proper size. By performing maintenance (secondary maintenance), it may be possible to achieve both efficiency of nail maintenance and measures against poor maintenance.

Further, in the above embodiment, when it is determined in the second inspection that the distance between the nails is not an appropriate dimension (first determination), for example, as shown in the step of S27 in FIG. The process of redevelopment of S35 is performed only for the obstacle nail 200 that is determined by the inspection (secondary determination) and that the dimensions are not appropriate in the re-inspection (secondary determination). By executing this, it is possible to prevent the second maintenance from being unnecessarily executed due to erroneous detection or erroneous determination, but the present invention is not limited to this, and these re-inspections are executed. It may not be.

Further, in the above embodiment, after the re-maintenance (secondary maintenance) is performed, the secondary re-inspection (S36) is executed again, and the nail determined to be not the proper size in the secondary re-inspection (S36). On the other hand, by performing re-maintenance (tertiary maintenance) with contents different from the red-maintenance (secondary maintenance) of S39, the nails that are not the proper dimensions due to the re-maintenance (secondary maintenance) are set to the proper dimensions. However, the present invention is not limited to this, and these re-maintenance (tertiary maintenance) may be the same as the re-maintenance (secondary maintenance), and these re-maintenance may be performed. It may be a form in which (tertiary maintenance) is not executed.

Further, in the above embodiment, the fault nail 200 that has undergone re-maintenance (tertiary maintenance) is subjected to a tertiary re-inspection (S40), and the tertiary re-inspection (S40) does not show that the dimensions are appropriate.
