The obstacle nail 200 is erected on the game board surface 2a by being driven by a nailing machine 16 described later in a hole 2d formed in advance on the game board surface 2a. The length L1 to the portion 200b is about 16.8 mm (L1 = about 16.8 mm). Further, a thread groove 200c is formed on the other end side of the body portion 200a. The screw groove 200c prevents the obstacle nail 200 from falling off the game board 2 due to a frictional force generated between the body portion 200a inserted into the hole portion 2d and the inner peripheral surface of the hole portion 2d.

  Further, as shown in FIG. 9A, the hole 2d for placing the obstacle nail 200 has a predetermined angle θ1 (θ1) directed upward with respect to the Z axis (perpendicular line) perpendicular to the game board surface 2a. = About 4 degrees). Therefore, since the obstacle nail 200 is also erected with the head 200b side inclined upward by about 4 degrees with respect to the Z axis (perpendicular), the game ball P that has collided with the obstacle nail 200 is as close to the game board 2 as possible. It tries to bounce.

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

  In this embodiment, the separation dimension L2 is about 10.5 mm and the separation dimension L3 is about 12 mm. However, the present invention is not limited to this, and these dimensions are the gauge configuration of the game board 2. Various changes can be made according to the so-called nail arrangement. Moreover, the separation dimension in the other designated nails 205-208 can also be set individually.

An upper plate 90 (hit ball supply plate) that is held (stored) is provided. A lower plate 91 that holds (stores) surplus balls overflowing from the upper plate 90 so as to be discharged to the outside of the pachinko gaming machine 1 is provided at the lower portion of the gaming machine frame 3. The tilting operation of the stick controller 31A attached to the member that forms the lower plate 91 is detected by a controller sensor unit (not shown), and is pressed against the push button 31B provided on the member that forms the upper plate 90. The operation is detected by a push sensor (not shown).

  Next, the circuit configuration of the pachinko gaming machine 1 will be described. On the back of the pachinko gaming machine 1, for example, a main board (not shown), an effect control board, an audio 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 substrates such as a substrate, a payout control substrate, an information terminal substrate, a launch control substrate, and an interface substrate are arranged.

  The main board (not shown) is a main-side control board on which various circuits for controlling the progress of the game in the pachinko gaming machine 1 are mounted. The main board is a sub-side control board mainly composed of a random number setting function used in a special figure game, a function of inputting a signal from a switch arranged at a predetermined position, an effect control board (not shown), etc. And a function of outputting and transmitting a control command as an example of command information as a control signal, a function of outputting various information to a hall management computer, and the like. In addition, the main board performs on / off control of each of the LEDs (for example, segment LEDs) constituting the first special symbol display 4A and the second special symbol display 4B, so that the first special diagram and the second special diagram are displayed. Controls the display of fluctuations of a predetermined display pattern, such as controlling the display of fluctuations and controlling the fluctuation display of the normal symbols by the normal symbol display 20 by turning on / off / coloring the normal symbol display 20. It also has a function to do. The main board is mounted with various circuits such as a game control microcomputer (not shown), a switch circuit (not shown), and a solenoid circuit.

  The main board is connected to a gate switch that detects a game ball that has passed through the passage gate 41, a first start port switch, a second start port switch, and a wiring that transmits a detection signal from the count switch. Further, display control is performed on the first special symbol display 4A, the second special symbol display 4B, the normal symbol display 20, the first hold indicator 25A, the second hold indicator 25B, the universal figure hold indicator 25C, and the like. Wiring for transmitting a command signal 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 change pattern designation command indicating a change pattern indicating a change mode such as a change time of an 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, a ROM (ReadOnly Memory) for storing a game control program, fixed data, and the like, and a RAM for providing a game control work area. (RandomAccessMemory102), a CPU (Central Processing Unit) that executes a control program by executing a game control program, a random number circuit that updates numeric data indicating a random number value independently of the CPU, and an I / O (Input / Outputport). 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 the CPU executing a program read from the ROM.

  The production control board (not shown) is a sub-side control board independent of the main board, receives the control signal transmitted from the main board via the relay board, and produces the production display device 5 and the speakers 8L and 8R. In addition, various circuits for controlling the rendering operation by electrical components for rendering such as various motors, solenoids, sensors, and light emitting diodes (LEDs) provided in the rendering LED 9 and other rendering units are mounted.

  An effect control board (not shown) includes an effect control CPU that performs a control operation in accordance with a program, an ROM that stores an effect control program and fixed data, 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 random values independently of the effect control CPU; O is mounted. As an example, in the effect control board, the effect control CPU executes an effect control program read from the ROM, thereby executing a process for controlling the effect operation by the effect electric parts. In addition to the program for effect control, the ROM stores various data tables used for controlling the effect operation.

  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 game ball has passed through the passing gate 41 provided in the gaming area 10, the normal game with the normal symbol display 20 is started. After the start of the normal symbol change, if the specified time, which is the normal symbol change time, has elapsed, and the normal symbols other than the normal symbol are displayed in a stopped state, the normal symbol change display result is “out of normal”. Become. If the specific normal symbol (the symbol per ordinary symbol) is stopped and displayed, the variation display result of the ordinary symbol becomes “per ordinary symbol”, and the expansion / release control (tilt control) of the ordinary variable winning ball apparatus 6B is performed, and the predetermined symbol is displayed. When time elapses, normal opening control for returning to the vertical position is performed.

  Based on the fact that the first start condition is satisfied after the first special condition game or the big hit game state has ended, for example, after the first start condition is satisfied because the game ball has won the first start winning opening, etc. Then, a special game is started by the first special symbol display 4A. In addition, after the second start condition is established because the game ball has won the second start winning opening, etc., the second start condition is established, for example, due to the end of the previous special game or the big hit game state. Based on this, a special game is started by the second special symbol display 4B.

  In the special game, after starting the variable display of the special symbol, the fixed special symbol (special graphic display result) is derived and displayed when the variable display time elapses. At this time, if a specific special symbol (big hit symbol) is displayed in a stopped state, the result is “big hit” as the specific display result, and if a special symbol different from the big hit symbol is displayed in a stopped state, it becomes “out of place”. After the fluctuation display result in the special figure game becomes “big hit”, the game is controlled to the big hit gaming state as a specific gaming state in which a round advantageous to the player (also referred to as “round game”) is executed a predetermined number of times.

  In the big hit gaming state, a special winning prize ball device 7 has a special prize opening door for a period until a predetermined upper limit time (for example, 29 seconds or 0.1 second) elapses or a predetermined number (for example, 9) of winning balls. In the period until the occurrence of, the grand prize opening is opened. Thereby, the round which makes the special variable winning ball apparatus 7 the 1st state (open state) advantageous for a player is performed.

  A special prize-winning ball device that receives a game ball falling on the surface of the game board 2 and then closes the big prize-winning slot, with the grand prize-winning door that has opened the grand prize-winning port during the round. 7 is changed to the second state (closed state) disadvantageous to the player, and one round is completed. The round that is the opening cycle of the big prize opening can be repeatedly executed until the number of executions reaches a predetermined upper limit number (for example, “16”, etc.).

  In the effect symbol display areas 5L, 5C, and 5R of the effect display device 5, in response to the start of the special symbol game, the effect symbol variable display is started. In the period from the start of the variation display of the effect symbol to the end of the variation display, the variation display state of the effect symbol may be a predetermined reach state. The reach state is a display in which variation continues for effect symbols that are not yet stopped when the effect symbols that are stopped and displayed in the display area of the effect display device 5 constitute a part of the jackpot combination. A state or a display state in which all or a part of the effect symbols change synchronously while constituting all or part of the jackpot combination.

  As a confirmed special symbol in the special figure game, among the multiple types of big hit combinations, the fixed effect symbol that is a predetermined normal big hit combination (also referred to as “non-probable variable big hit combination”) is stopped and displayed, and the variation display result is “non-probable big hit bonus”. ”Is controlled to the big hit state, and after the end, time reduction control (time reduction control) is performed. By performing the time reduction control, the special symbol change display time (special figure change time) in the special figure game is shortened compared to the normal state. In the short-time control, so-called electric Chu support is performed in which the winning frequency of the normal symbol is increased and the winning frequency to the normal variable winning ball apparatus 6B is increased. In the time-saving control, one of the conditions is established first, that is, a special game is executed a predetermined number of times (for example, 100 times) after the big hit gaming state ends, and the fluctuation display result is “big hit”. Sometimes it just needs to end.

  As a confirmed special symbol in the special figure game, among the multiple types of big hit combinations, the finalized design symbol that becomes a predetermined probability variable big hit combination (also referred to as “probable big hit combination”) is stopped and the fluctuation display result is “probable big hit” When it becomes, it is controlled to the big hit state, and after the end, probability variation control (probability variation control) is performed together with time reduction control. By performing the probability variation control, the probability that the variation display result is “big hit” in each special figure game is improved so as to be higher than that in the normal state. When the condition that the variable display result is “big hit” and the game is controlled again to the big hit gaming state after the end of the big hit gaming state is established, the probability variation control is performed a predetermined number of times after the big hit gaming state ends (for example, the same as the number of time reductions 100) When the special figure game is executed, the probability variation control lottery executed every time the special figure game is started after the jackpot game state is finished is determined to have “probable fall”. When it ends, etc.

  When the short-time control is performed, the normal symbol variation time (normal diagram variation time) in the regular game is shorter than that in the normal state, and the regular symbol variation display result is “normal diagram” in each regular game. The tilt control time for performing the tilt control of the movable blade piece in the normal variable winning ball apparatus 6B based on the fact that the probability of “winning” is higher than that in the normal state, and the fluctuation display result is “normal hitting”. The second start condition can be established by making it easier for the game ball to pass (enter) the second start winning opening, such as control for making it longer than in the normal state, and control for increasing the number of tilts than in the normal state. Control (electricity chew support control, high opening control) that is advantageous for the player by enhancing the performance is performed. As a result, the second start condition for executing the special figure game using the second special figure is likely to be established, and the special figure game can be executed frequently. Time to become is shortened.

  Next, the operation (action) of the pachinko gaming machine 1 in this embodiment will be described. In the main board (not shown), when power supply from a predetermined power supply board is started, a game control microcomputer (not shown) is activated, and a predetermined process which is a game control main process by the CPU (not shown). Is executed. When game control timer interrupt processing is started in the game control main processing, switch processing, main-side error processing, information output processing, game random number update processing, special symbol process processing, normal symbol process processing, and command control processing are executed.

  In the special symbol process, the CPU first determines whether or not there has been a first start winning or a second starting winning. If there is a winning, the special symbol display result determination, jackpot type determination, variation pattern A random number value for determination or the like is extracted, and a start winning process is executed for storing (storing) at the highest level of empty entries in the first special figure reservation storage unit or the second special figure reservation storage unit.

  Further, the CPU determines whether or not to start the special game based on the presence or absence of the hold data stored in the first special figure hold storage unit or the second special figure hold storage unit, and the special figure display result. A special decision that determines (predetermines) whether or not the variation display result of a special symbol or production symbol is to be a “hit” based on numerical data indicating a random number for judgment before the variation display result is derived and displayed. The symbol normal process is executed. In other words, the CPU determines 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 occurs when starting the variable display of the special figure game. Processing to determine (lottery) is executed.

  Next, a variation pattern setting process for determining a variation pattern as one of a plurality of types, a special symbol variation process for performing a setting for varying a special symbol and a process for measuring an elapsed time after the special symbol starts variation, A special symbol stop process is performed to perform settings for stopping the change of the special symbol and stopping and displaying (deriving) the fixed special symbol. In addition, when the variation display result is “big hit”, the big hit release pre-processing, the big hit open process, the big hit release post-processing, and the big hit end process are performed to open and close the big winning opening in the big hit gaming 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 interruption occurs in the main process, a command analysis process, an effect control process, and an effect random number update process are executed.

  In the effect control process, the hold display update process for updating the hold storage display in the first hold storage display area 5D and the second hold storage display area 5U of the display display device 5 to a display corresponding to the storage contents of the hold storage buffer. Execute. Next, according to the value of the effect control process flag, control is performed so that the variation pattern designation command reception waiting process for confirming whether or not the variation pattern designation command is received from the game control microcomputer is started, and the variation of the effect symbol is started. In addition to monitoring the switching timing of each variation state (variation speed) constituting the variation pattern and the end of the variation time according to the process data set in the production symbol variation start process and the production symbol variation start process, Display control of the effect display device 5, output of sound from the speakers 8L and 8R, light emission of the effect LED 9 and drive control of the effect unit (not shown), etc. An effect symbol variation stop process is performed for performing control for deriving and displaying (stop symbol).

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

The game board 2 that has been determined that dust of a predetermined amount or more has not adhered is directly attached with the seal 15 by the first two-dimensional code marking device 14a, and the game board 2 that has been determined to have dust of a predetermined amount or more has adhered. 2 is conveyed to the ionizer device 18, and after dust is removed, a seal 15 is applied by the second two-dimensional code marking device 14 b.

  As shown in FIG. 5, the various devices constituting the production line 12 are connected to a control device 500 that controls the production line 12 so that data communication is possible. The control device 500 is associated with the serial code assigned to each game board 2, the type of each game board 2, maintenance data for maintaining the obstacle nail 200 by the obstacle nail maintenance device 300, maintenance history information (game board) 2), the storage unit 502 that stores information that can identify the nailing machine 16 and the troubled nail maintenance device 300, information that indicates the contents of maintenance, and the like, and operation control of various connected devices are performed. And a control unit 501 that performs processing for determining the transport destination of the game board 2, processing for transmitting maintenance data corresponding to each game board 2 to various devices, and the like.

  As described later, each device has a serial code read from a two-dimensional code 15a printed on a sticker 15 affixed to the game board 2 and device identification information (hereinafter referred to as device ID) that can identify each device. While transmitting to the control part 501, it operate | moves based on the operation data, maintenance data, etc. which were transmitted from the control part 501. Although not shown, the control device 500 is also connected to a transfer device 13 that connects various devices, the above-described sensors, each two-dimensional code reader, a hygrometer / thermometer described later, and the like.

  Next, a rough flow of the manufacturing process of the game board 2 in the pachinko gaming machine 1 will be described. FIG. 6 is a flowchart showing a rough flow of a game board manufacturing process. In the following manufacturing process, the game board 2 that has completed one process is transported by the transport apparatus 13 to the apparatus for performing the next process (see FIG. 4).

  First, a predetermined size synthetic resin material (for example, an acrylic board) or a plywood board constituting the game board 2 is cut or drilled by a router or the like into a predetermined shape, and then a cell sheet is placed on the game board surface 2a. Affix. Next, in order to reduce misalignment during driving operations such as nails and windmills, a metal gauge plate (not shown) formed according to gauge data (nail arrangement data) corresponding to the type of game board 2, An operation for machining a pilot hole in the game board surface 2a is performed (step S1).

  When the work for forming the pilot hole on the game board surface 2a is completed, the first 2D code marking device 14a or the second 2D code marking device 14b uses the development code indicating the type of the game board 2, gauge data (nail arrangement data). ) And maintenance operations (maintenance data to be described later), etc., a subcode indicating a serial number, a serial number indicating a manufacturing number (unique ID), a nail driver code indicating a nailing machine 16, and a material code indicating a material of the game board 2 Then, an operation for printing the various codes including the individual two-dimensional code 15a in which the print date code indicating the date and time printed on the seal 15 to be described later is encoded and pasting the seal 15 is performed (step S2).

  As described above, in the production line 12, the game boards 2 having different types can be manufactured, and the maintenance contents of the nail arrangement and the obstacle nail 200 are different depending on the type of the game board 2. Therefore, various devices provided in the production line 12 read the two-dimensional code 15a printed on the seal 15 with a two-dimensional code reader (not shown), and transmit the read serial code and device ID to the control device 500. To do. In the control device 500 that has received the serial code, the maintenance data corresponding to the serial code, that is, the maintenance data corresponding to the game board 2 specified from the serial code is extracted from the storage unit 502 and the maintenance data is received. The data is transmitted to the transmission source device specified by the ID. Various devices perform maintenance based on the maintenance data received from the control device 500.

  Further, in the production line 12, a plurality of nailing machines 16 and obstacle nails installed in the production line 12 are used in nailing (step S3), first maintenance (step S5), second maintenance (step S6), which will be described later. Among the maintenance devices 300 and the like, there may be a deficiency in nailing with the nailing machine 16 with which the predetermined game board 2 is involved or maintenance with the obstacle nail maintenance device 300.

  As described above, in the production line 12, the specification is such that in the process from the nail driving to the final inspection (process S <b> 3 to process S <b> 7), it is distributed to the devices that are vacant in each process. Since maintenance or nailing is not determined in advance, the maintenance history of each game board 2 is stored in the storage unit 502 so that the device related to each game board 2 can be specified. As the maintenance history information is accumulated, it becomes possible to identify which of the various devices has a large number of maintenance defects. Therefore, the maintenance work for a plurality of devices installed in the production line 12 can be performed. It is possible to carry out simply.

  In addition, by storing the maintenance history of each game board 2 in the storage unit 502, when a failure of a failure nail is found after 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 2 2 can identify a device involved in the manufacturing process, that is, a device having a possibility of malfunction, so that a new game board 2 may be maintained by the device having the possibility of malfunction. As a result, it is possible to cope with the problem early, such as immediately stopping the driving of the apparatus and performing maintenance work.

  Further, in step S2, the seal 15 on which the two-dimensional code 15a is printed is below the board surface plate 2A (for example, a position where the seal 15 is not exposed from the outside when mounted on the pachinko gaming machine 1. In the present embodiment, the lower right position) The work of pasting to is performed (see FIG. 2). Further, the seal 15 is provided with a two-dimensional code provided at a predetermined position on the production line 12 (for example, each nail driver 16, each nail maintenance device 300, the first nail inspection device 17A, the second nail inspection device 17B). In addition to the two-dimensional code 15a read by a reader (not shown), a development code 15b, a subcode 15c, a serial code 15d, a nail driver code 15e, a material code 15f, and a print so that the operator can visually confirm The date code 15g and the like are written with alphabets, numbers, symbols, and the like (see FIG. 14).

  In this embodiment, since the order of transporting the game board 2 to the first two-dimensional code marking device 14a or the second two-dimensional code marking device 14b through the step S1 is determined in advance, the first two-dimensional code marking The device 14a and the second two-dimensional code marking device 14b do not need to specify the type of the game board 2, but a one-dimensional code or the like that can specify a serial code is pasted on the game board 2 in step S1. The type of the game board 2 may be specified based on the serial code specified from the one-dimensional code by the first two-dimensional code marking device 14a or the second two-dimensional code marking device 14b.

  In the present embodiment, a seal 15 printed with a two-dimensional code 15a is attached to the board 2A so that the two-dimensional code 15a can be read by a two-dimensional code reader (reading device) not shown. However, the present invention is not limited to this, and a sticker including an IC chip in which various kinds of information are stored is pasted, and the information stored in the IC chip can be read by a predetermined reading device.

  When the marking operation of the two-dimensional code 15a is finished on the board surface plate 2A, the nailing machine 16 performs the operation of driving the plurality of obstacle nails 200 into the pilot holes processed in the step S1 (step S3). When the driving operation of the obstacle nail 200 is completed, 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 described later (see FIG. 13). Based on the nail image inspection, each obstacle nail 200 is inspected with respect to the Z-axis direction orthogonal to the game board surface 2a (position coordinates of the head 200b), presence / 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 inspection result data to the control device 500 together with data that can specify the device ID of the first nail inspection device 17A.

  The control unit 501 of the control device 500 that has received the inspection result data determines whether each obstacle nail 200 is inclined upward by about 4 degrees with respect to the Z-axis direction orthogonal to the game board surface 2a based on the received inspection result data. Whether or not the position shift direction and the amount of position shift 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 is determined. The setting position (coordinate position) of the head 200b of each obstacle nail 200 is a position where the head 200b is disposed when the obstacle nail 200 is accurately driven into the pilot hole, and corresponds to the type of the game board 2 It is stored in the storage unit 502 of the control device 500 as gauge data.

  In addition, for each set position, an allowable range (accuracy) in consideration of an error in the XY axis direction is set, and when the head 200b is disposed outside this allowable range, it is determined that there is an abnormality, The direction and amount of deviation from the set position are specified. The allowable range can be set to a desired value for each obstacle nail 200 as described later (see FIGS. 15 and 16).

  The control unit 501 that has received the inspection result data determines that, among the obstacle nails 200 driven in step S3, the deviation in the XY-axis direction with respect to the set position of the head 200b is out of the allowable range by the inspection in step S4. The first maintenance data for placing the head 200b of the obstacle nail 200 within the allowable range of the set position is created for the obstacle nail 200, and the first maintenance data is used as the obstacle of the transport destination of the game board 2 Transmit to the nail maintenance device 300 to instruct execution of the first maintenance.

  The obstacle nail maintenance device 300 performs first maintenance for the obstacle nail 200 in which an abnormality is detected in step S4 based on the first maintenance data received from the control device 500 (step S5).

  Further, the control unit 501 of the control device 500 conveys the game board 2 that has undergone the first maintenance to the second nail inspection device 17B, and the camera 44 of the second nail inspection device 17B for the obstacle nail 200 after the first maintenance. Accordingly, 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 based on the positional deviation direction and positional deviation in the XY-axis direction with respect to the set position of the head 200b. A first inspection is performed based on the amount. The first inspection and the first maintenance are repeated until the head 200b of the obstacle nail 200 after the first maintenance is arranged within the allowable range of the set position.

  In the present embodiment, the game board 2 that has completed the operation of the step S4 performs the first maintenance only for the faulty nail 200 in which the abnormality is detected, but the present invention is limited to this. The first maintenance may be performed for all the obstacle nails 200 regardless of whether there is an abnormality.

  Next, the control unit 501 targets the obstacle nail 200 (for example, designated nails 204 to 208) designated in advance according to the type of the game board 2 among the plurality of obstacle nails for the game board 2 for which the first inspection has been completed. Then, the second maintenance data for arranging the head 200b of the obstacle nail 200 within the allowable range of the designated position is transmitted to the obstacle nail maintenance device 300 to instruct execution of the second maintenance. The obstacle nail maintenance 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 (step S6).

  Specifically, in the second maintenance, for example, the gap between the pair of obstacle nails 200 in each of the designated nails 204 to 208 is gradually expanded from the base side toward the head 200b side so as to have a desired dimension (FIG. 3B). 9B), the head 200b is arranged at a designated position different from the set position. In addition, it includes maintenance for changing the inclination angle, the inclination direction of each obstacle nail 200, the arrangement mode with other obstacle nails 200, etc., regardless of whether or not the maintenance nail 200 was maintained in the first maintenance in step S5. Done.

  In addition, for each specified position, an allowable range (accuracy) considering an error in the XY axis direction is set, and when the head 200b is disposed outside the allowable range, it is determined that there is an abnormality and the specified position is specified. The direction and amount of deviation from the position are specified. As will be described later, this allowable range can be set to a desired value for each obstacle nail 200 (see FIGS. 15 and 16).

  These designated nails 204 to 208 are related to the probability of entering a game ball into each winning opening and passing gate 41 related to the provision of game value among the plurality of obstacle nails 200 driven into the game board surface 2a. This is a fault nail that is highly likely to affect the base value of the pachinko gaming machine 1 by a slight error or deviation. Further, the inclination angle, the inclination direction, and the arrangement mode of the other obstacle nails 200 are changed according to the type of the game board 2. As will be described later, this designated nail can designate a desired obstacle nail 200 for each game board 2 (see FIG. 17).

  As described above, the first maintenance is for the failure nail 200 in which the abnormality is detected in step S4 among the plurality of failure nails 200 driven into the game board surface 2a in step S3. The second maintenance is intended for a predetermined designated obstacle nail (e.g., designated nails 204 to 208) and includes the operation of placing the head 200b of the user within the allowable range of the set position. This includes the operation of placing the head 200b of the obstructed nail 200 within the allowable range of the designated position. In other words, the second maintenance and the step S6 for performing the second maintenance perform maintenance different in contents from the first maintenance and the step S5 for performing the first maintenance.

  The second maintenance is a maintenance that cannot be made uniform or difficult in the nailing process by the nail driving device 16, and requires a delicate work with higher accuracy than the first maintenance. By performing the maintenance separately from the first maintenance for 200, the maintenance work of the obstacle nail 200 can be performed efficiently. Further, in the game board 2 of the type that does not require the second maintenance for the designated nails 204 to 208, the second maintenance in the step 6 may be omitted.

  Further, in this step S6, after the second maintenance is performed for each of the designated nails 204 to 208, a method different from the final inspection (step S7) by the second nail inspection device 17B is performed using a maintenance tool 400 described later. Thus, a second inspection to be described later for determining whether or not the obstacle nail 200 of the designated nails 204 to 208 is disposed within the allowable range of the designated position is included. The second inspection and the second maintenance are repeated until the head 200b of the obstacle nail 200 after the second maintenance is disposed within the allowable range of the designated position.

  When the second maintenance and the second inspection for the designated nails 204 to 208 are completed, the head 200b of each obstacle nail 200 is in the set position for all the obstacle nails 200 in the second nail inspection device 17B. Whether or not the final inspection is performed (step S7). In the present embodiment, in step S7, the positions of all the obstacle nails 200 of the game board 2 are inspected. However, the present invention is not limited to this, and only the designated nails 204 to 208 are used. You may make it test | inspect. Furthermore, in the present embodiment, all the game boards 2 are confirmed by the second nail inspection device 17B, but the present invention is not limited to this, and any one of the plurality of game boards 2 may be inspected ( For example, 1 in 1000 units). In addition, the game board 2 in which an abnormality is detected in step S7 is taken out from the production line 12, and is maintained again by the obstacle nail maintenance device 300 or the like different from the production line 12.

  If there is no abnormality, an operation of attaching the guide rail 2b and the windmill using the prepared holes formed in the game board surface 2a is performed (step S8). And after attaching other game members, such as the center decoration frame 51 and various winning devices, it is assembled | attached to the game machine frame 3 of the pachinko game machine 1 (process S9). If there is an abnormality in step 7, maintenance of steps S5 and S6 is performed again. Finally, the completed pachinko gaming machine 1 is packed and shipped (step S10).

  Next, the obstacle nail maintenance device 300 that performs the first maintenance and the second maintenance of the obstacle nail 200 performed in the steps S5 to S7 will be described with reference to FIGS.

  As described above, the maintenance arm 301 formed of a multi-joint arm is connected to the control device 500 described above, and is built in the base 310 and each arm based on a command from the control unit 501 of the control device 500. When the driving source (not shown) such as a motor is driven, the maintenance tool 400 is moved in the horizontal direction (front / rear / left / right direction, XY axis direction) along the game board surface 2a or in the vertical direction ( It can be moved in the vertical direction (Z-axis direction) or tilted with respect to the Z-axis.

  In this embodiment, the maintenance arm 301, which is an example of the operation means for operating the maintenance tool 400, is configured by an articulated arm, but the present invention is not limited to this, and the maintenance arm 301 is not limited thereto. Any tool other than the articulated arm may be used as long as the tool 400 can be moved in the XY axis direction or the Z axis direction or tilted with respect to the Z axis.

  Clamps 320 are provided at a plurality of locations (four locations in this embodiment) on the upper peripheral edge of the table 302. The game board 2 faces upward on the table 302, and the game board surface 2a faces upward so that the obstacle nail 200 faces upward. It can be fixed horizontally in the state. Further, the game board 2 can be exchanged if the fixation by the clamp 320 is released.

  As shown in FIG. 7, the maintenance tool 400 includes a rod-shaped portion 401 made of a metal rod-shaped member having a diameter φ10 of about 6 mm (φ10 = about 6 mm), and a metal material attached to the lower end side of the rod-shaped portion 401. The upper end of the rod-like portion 401 can be attached to the head 317 in a replaceable manner.

  As shown in FIG. 9, the clamping part 403 which clamps the trunk | drum 200a is formed in the rectangular parallelepiped shape which makes a substantially horizontal rectangular shape in front view, and is wider than the diameter (phi) 1 (outer diameter) of the trunk | drum 200a on the front left and right side. Concave grooves 411L and 411R having a left-right dimension as an interval are formed in the vertical direction. A rod-shaped portion 401 is connected to the center of the upper surface of the sandwiching portion 403 in the left-right direction, and the sandwiching portion 403 is provided so as to be substantially orthogonal to the rod-shaped portion 401.

  Further, the left and right side corners on the back side of the sandwiching part 403, the inner side corners in the upper and lower openings of the grooves 411L and 411R, the outer side corners in the lower openings of the grooves 411L and 411R, and the lower surface of the sandwiching part 403 The left and right side corners are each chamfered.

  In this way, the chamfering process is performed on the corners of each side, so that the obstacle nail 200 or the game board surface 2a may be damaged when performing maintenance work by holding the body 200a with the holding part 403. Is prevented.

  The obstacle nail servicing device 300 configured in this manner is the process S3 among the plurality of obstacle nails 200 placed on the game board surface 2a using the maintenance tool 400 in the step S5 in the manufacturing process of the game board 2 described above. A first maintenance for maintaining the faulty nail 200 in which an abnormality is detected in step 1 based on the first maintenance data, and a second maintenance for maintaining the designated nails 204 to 208 specified in advance in step S6 based on the second maintenance data. Do.

  Next, the contents of the second maintenance of the designated nails 204 to 208 performed by the obstacle nail maintenance apparatus 300 in step S6 will be described with reference to FIGS. In the following, the second maintenance content of the designated nail 204 will be described as an example, and description of the second maintenance content of the other designated nails 205 to 208 will be omitted.

  As shown in FIG. 9, when the right and left obstacle nails 200, which are designated nails 204, are driven by the nailing machine 16, the left and right obstacle nails 200 are arranged with respect to the Z-axis direction perpendicular to the game board surface 2a. Inclined upward by about 4 degrees. Further, at the set position, the separation dimension L2 on the base end side and the separation dimension L3 on the head part 200b side of the body part 200a of each of the left and right obstacle nails 200 are respectively 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 trunk portions 200a are substantially parallel to each other. In the second maintenance, the distance between the right and left 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 arranged at a designated position where the separation dimension L3 is about 12 mm. Based on the data.

  Based on the second maintenance data received from the control device 500, the obstacle nail maintenance device 300 operates the holding portion 403 of the maintenance arm 301 by a driving source (not shown) 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 control device 500 when maintaining the designated nail 204 of the game board 2 formed from the plywood board. And the operation pattern data for the plywood plate for operating the holding portion 403 of the maintenance arm 301 based on the water content. As described above, since the designated nail 204 of the plywood game board 2 can be maintained in accordance with changes in the indoor environment (humidity / temperature) in the factory, the plywood can be prevented from being damaged during the maintenance work of the designated nail 204. , Maintenance accuracy increases.

  The maintenance tool 400 includes not only the maintenance tool 400 described above, but also a plurality of types of maintenance tools having dimensions and shapes according to the type of the game board 2 and the target obstacle nail 200. The replacement is possible according to the obstacle nail 200 to be maintained. Note that such a selection and replacement operation of the maintenance tool 400 is included in the second maintenance data, and the maintenance arm 301 is automatically performed according to the obstacle nail 200 to be maintained. It may be possible for a person to change the hand manually.

  The obstacle nail maintenance device 300 drives the maintenance arm 301 with a predetermined operation pan turn based on the received second maintenance data, and from the initial driving position to the arrangement position of the designated nail 204 to be maintained. The nipping portion 403 is moved above the game board 2 so as not to contact the obstacle nail 200.

  Next, as shown in FIG. 9A, the holding 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 by the white arrow direction in FIG. 9A, the clamping portion 403 is moved rearward, and the body portions 200a of the right and left obstacle nails 200 are fitted into the concave grooves 411L and 411R, respectively. Place in one position. Thereby, the trunk | drum 200a of the right and left obstacle nail 200 is clamped by the concave grooves 411L and 411R. As shown in FIG. 9A, the sandwiching portion 403 is inclined at a predetermined angle (about 4 degrees) upward with respect to the Z axis (perpendicular) as shown in FIG. 9A.

  In the first position, as shown in FIG. 9A, the lower surface of the holding 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 clamping part 403 is arrange | positioned in the position of the base side nearer to the game board surface 2a than the head 200b in the trunk | drum 200a. Further, the rod-shaped portion 401 is disposed in a state inclined at a predetermined angle θ1 (θ1 = 4 degrees) upward with respect to the Z axis (perpendicular) so as to be parallel to the trunk portion 200a of the obstacle nail 200. The vertical dimension L5 of the clamping part 403 is shorter than the length L1 from the game board surface 2a to the head part 200b of the obstacle nail 200 (L5 <L1). Since it is separated from 200b, the clamping part 403 can be slid toward the head 200b.

  Next, as shown in FIG. 9 (B), the clamping part 403 is divided into a plurality of times while swinging the bar-like part 401 to the left and right by a predetermined angle with respect to the center position CP in the horizontal direction on the lower surface of the clamping part 403. Move to.

  Specifically, the sandwiching portion 403 is tilted with a predetermined angle θ2 (θ2 = about 13.15 degrees) inclined toward the right side with respect to the center position CP in the left-right direction on the lower surface of the sandwiching portion 403. The operation is stopped for a predetermined period (for example, about 0.6 seconds) in the state. Next, the clamping unit 403 is moved from the first position toward the direction inclined about 4 degrees upward with respect to the Z-axis direction by a first movement amount (for example, about 0.35 mm) and disposed at the second position. 9 (B), after the sandwiching portion 403 is returned to the Z-axis by tilting the rod-like portion 401 toward the left side with respect to the center position CP by a predetermined angle θ2 (θ2 = about 13.15 degrees), The operation is stopped for a predetermined period (for example, about 0.6 seconds) in a tilted state with a predetermined angle θ3 (θ3 = about 12.25 degrees) inclined toward the left side.

  In this way, when the clamping part 403 is tilted in the left-right direction with respect to the center position CP, the obstacle nail 200 on the side where the rod-like part 401 is swung is bent more than the obstacle nail 200 on the other side. By repeating a plurality of times, the interval between the obstacle nails 200 of the designated nail 204 is maintained so as to gradually widen from the base side toward the head 200b side. By such second maintenance, the head 200b of each designated nail 204 is disposed within the allowable range of the designated position.

  Next, the control unit 501 of the control device 500 transports the game board 2 that has undergone the second maintenance to the second nail inspection device 17B, and the head 200b of the designated nail 204 that has undergone the second maintenance is allowed to be in the designated position. A second inspection is performed to determine whether or not it is located within the range. In this second inspection, in addition to whether or not the head 200b of the faulty nail 200 that has been second serviced is disposed within the allowable range of the designated position, the bending state of the trunk 200a of the faulty nail 200 is normal. It is determined whether or not.

  First, after the second maintenance is completed, the maintenance tool 400 is replaced with an inspection tool 600 shown in FIG. The inspection tool 600 includes a rod-like portion 601 made of a metal rod-like member having a diameter φ10 of about 6 mm (φ10 = about 6 mm), and a measuring portion 602 made of a metal material attached to the lower end side of the rod-like portion 601. It is mainly composed. The measuring unit 602 includes a base 602a that is fixedly installed on the lower end side of the rod-shaped portion 601 and a moving unit 602b that is provided so as to be relatively movable with respect to the base 602a. As shown in FIG. 12, the moving part 602b has a plate-like piece extending forward from the lower end of the rod-like part 601. At the tip of the plate-like piece, the first contact side 602L and the first piece A substantially V-shaped cutout portion 603 in plan view having a second contact side 602R disposed so as to intersect with the contact side 602L is formed. It should be noted that the phrase “disposed so as to intersect” may mean that the first contact side 602L and the second contact side 602R are in contact with each other and intersect, or the first contact side 602L and the second contact side. Although it is separated from 602R without contacting, it may be arranged so as to intersect on the extension line of each contact side. That is, it is only necessary that the contact sides are arranged at different angles.

  The measuring unit 602 configured as described above is a so-called force sensor (which can measure a shearing force on the base 602a and a direction in which the shearing force is applied by moving the moving unit 602b in the XYZ axial directions with respect to the base 602a. It is also called a strain gauge sensor. A valley portion of the substantially V-shaped cutout portion 603 is a base point RP.

  Next, as shown in FIG. 11, using the inspection tool 600, the XY axis direction at a plurality of locations in the Z-axis direction of the trunk portion 200a of the obstacle nail 200 (in this embodiment, two locations of inspection points P1 and P2). Measure the position (coordinates). Then, a calculation unit (not shown) provided in the base 602a detects the bending state of the obstacle nail 200 based on the position data (coordinate data).

  Specifically, as shown in FIG. 12A, 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. 12B, the inspection tool 600 is moved in the XY-axis direction (horizontal direction) so that the base point RP is arranged at the specified position. That is, if the designated nails 204 to 208 are disposed within the allowable range of the designated position by the second maintenance, the first contact side 602L and the second contact side 602R are not in contact with the trunk portion 200a and the base point RP is inspected. It can be moved from the position to the specified position.

  However, if the obstacle nail 200 is not disposed within the allowable range of the designated position, the obstacle nail 200 is placed on one of the first contact side 602L and the second contact side 602R (for example, the second contact side 602R). When contact is made, pressure acts in the direction of the dotted arrow in FIG. 12B, and thereby the moving portion 602b moves relative to the base portion 602a. Therefore, the shearing force on the base portion 602a and the direction in which the shearing force is applied are measured. The obstacle nail servicing device 300 guides the inspection tool 600 in the direction in which the shearing force and the direction thereof decrease (the direction of the minimum value). The operation as described above is repeated, and the base point RP of the inspection tool 600 is disposed at a position where it contacts the obstacle nail 200 as shown in FIG. The obstacle nail maintenance device 300 transmits to the control device 500 second inspection result data including the amount of movement and the direction of movement of the base point RP of the inspection tool 600 until the base point RP contacts the obstacle nail 200.

  The control unit 501 that has received the second inspection result data specifies the amount of deviation in the XY-axis directions of the positions of the inspection points P1 and P2 with respect to the designated position, based on the second inspection result data. That is, the load applied when the control unit 501 contacts the first contact side 602L or the second contact side 602R while moving the base point RP between the first contact side 602L and the second contact side 602R toward the specified position. Thus, the degree of bending of the body 200a is specified based on the amount of deviation from the designated position at each of the inspection points P1 and P2.

  As described above, the control unit 501 not only determines the amount of deviation in the XY axis direction with respect to the specified position of the head 200b of the obstacle nail 200, but also each inspection point that is a position different from the head 200b in the Z axis direction. By determining the amount of deviation in the XY-axis direction with respect to the designated position of the body part 200a in P1 and P2, the degree of bending of the body part 200a of the obstacle nail 200 is specified.

  Further, by identifying the bending state of the obstacle nail 200 from the amount of deviation in the XY axis direction with respect to the designated position of the trunk portion 200a at each inspection point P1, P2, the length of the head 200b of the obstacle nail 200 from the game board surface 2a is determined. Dimension can be specified. That is, even if the head 200b does not deviate from the set position in the XY axis direction, it is possible to grasp a problem that the trunk 200a is bent, so that the planted state of the obstacle nail 200 can be inspected with high accuracy.

  For the fault nail 200 in which an abnormality is detected in the second inspection performed after the completion of the second maintenance in step S6, the control unit 501 creates corrected maintenance data corresponding to the second maintenance data, and uses the corrected maintenance data as the corrected maintenance data. Based on this, the holding portion 403 of the maintenance arm 301 is operated. The second maintenance and the second inspection are repeated until the head 200b of the obstacle nail 200 after the second maintenance is disposed within the allowable range of the designated position.

  In the present embodiment, in the second inspection, the control unit 501 moves the first contact side 602L or the second contact point 602L or the second contact side 602R while moving the base point RP between the first contact side 602L and the second contact side 602R toward the specified position. Although the form which specifies the bending condition of the trunk | drum 200a based on the deviation | shift amount from the designated position in each test | inspection point P1, P2 by the load applied when contacting the contact edge 602R was illustrated, this invention is limited to this. When it is detected that the obstacle nail 200 is in contact with the base point RP, the position of the base point RP (the amount of movement and the direction of movement of the base point RP from the inspection start position to the position where it contacts the obstacle nail 200) (Movement trajectory)), the amount of deviation from the designated position at each of the inspection points P1 and P2 may be measured to specify the degree of bending of the body 200a. The contact with the base point RP means that the first contact side 602L and the second contact side 602R intersect (the first contact side 602L and the second contact side 602R do not contact each other as in this embodiment). In the case of being separated from each other, the contact is not limited to contact with an imaginary intersection on the extension line of each contact side, but is in contact with a portion near the intersection in the first contact side 602L and the second contact side 602R. It is also included. The vicinity of the intersection means, for example, when a member having a circular cross section such as the obstacle nail 200 is brought closest to the base point RP, the obstacle nail 200 is moved to the first contact side 602L and the second contact side 602R. The part etc. which contact is included.

  Further, in this embodiment, when the obstacle nail 200 comes into contact with the first contact side 602L or the second contact side 602R, the shearing force applied by the contact and the direction in which the direction decreases (the direction of the minimum value). Although the inspection tool 600 is guided, the inspection tool 600 may be guided without considering the shearing force and its direction. For example, when the obstacle nail 200 comes into contact with the first contact side 602L at a site different from the vicinity of the base point RP, the inspection tool 600 is guided to approach the second contact side 602R and the base point RP, and the obstacle nail 200 is guided to the base point RP. When the second contact side 602R is contacted at a site different from the vicinity, the inspection tool 600 may be guided so as to approach the first contact side 602L and the base point RP. That is, the inspection tool 600 may be guided so as to approach a contact side that is different from the contact side that is in contact without considering the shearing force and the direction thereof.

  Further, as a method for detecting that the obstacle nail 200 is in contact with the base point RP, when the external force applied to the measurement unit 602 when the obstacle nail 200 is in contact is greater than a specific value, the obstacle nail 200 contacts the base point RP. You may determine that you are doing. When the obstacle nail 200 comes into contact with the first contact side 602L or the second contact side 602R in the middle of guiding the base point RP toward the obstacle nail 200, a space for allowing the obstacle nail 200 to escape toward the base point RP is provided. Therefore, the external force applied to the measurement unit 602 is less than a specific value. However, when the obstacle nail 200 comes into contact with the base point RP, the obstacle nail 200 cannot be released, so that the external force applied to the measurement unit 602 becomes a specific value or more. From this, when the base point RP is guided toward the obstacle nail 200, when the external force applied to the measurement unit 602 is less than a specific value, the inspection tool 600 is contacted differently from the contact side that is in contact as described above. When the external force applied to the measurement unit 602 is equal to or greater than a specific value, the obstacle nail 200 may be determined to have contacted the base point RP.

  The method for detecting that the obstacle nail 200 is in contact with the base point RP is not limited to the above-described external force, but optical detection using infrared rays, electromagnetic induction detection, capacitance detection, and the like. May be used.

  Further, as a method for detecting that the obstacle nail 200 is in contact with the base point RP, when it is detected that the obstacle nail 200 is in contact with both the first contact side 602L and the second contact side 602R at the same time, It may be determined that the nail 200 is in contact with the base point RP.

  The measurement unit 602 according to the present embodiment includes a first contact side 602L and a substantially V-shaped notch 603 in plan view having a second contact side 602R arranged to intersect the first contact side 602L. Is formed. As in Patent Document 2, when the position of the obstacle nail 200 is detected by a position detection device provided with a ball probe at the tip of an articulated arm and capable of detecting the position of the ball probe by calculation, the ball portion is pinpointed. There is a possibility that the operation control of the apparatus becomes complicated because the obstacle nail must be brought into contact. On the other hand, in the measurement unit 602 in this embodiment, the position is detected by bringing the obstacle nail into contact with the base point RP, but the first contact side 602L and the second contact side 602R are in the vicinity of the base point RP. Arranged to form a V-shaped space toward the base point RP. Accordingly, even if the obstacle nail 200 is not brought into contact with the base point RP at the pin point, the base point RP is guided toward the obstacle nail if it is brought into contact with either the first contact side 602L or the second contact side 602R. The obstacle nail 200 can be easily brought into contact with the base point RP.

  In this embodiment, the second inspection is performed using the inspection tool 600. However, the present invention is not limited to this, and the second inspection is performed by a camera like a nail image inspection. You may do it.

  Next, the inspection of the obstacle nail 200 performed by the first nail inspection device 17A and the second nail inspection device 17B in steps S4 and S7 will be described with reference to FIG. 13A is a plan view showing the internal structure of the first nail inspection device and the second nail inspection device in FIG. 4, and FIG. 13B is a cross-sectional view taken along the line BB in FIG. Since the first nail inspection device 17A and the second nail inspection device 17B in this embodiment have the same configuration, only the configuration of the first nail inspection device 17A will be described, and the description of the configuration of the second nail inspection device 17B will be omitted. To do.

  As shown in FIG. 13, the first nail inspection device 17 </ b> A includes a rectangular frame 43 in a plan view arranged at a predetermined height by a plurality of standing leg portions 42, and a lower center side of the frame 43. That is, a plurality of cameras 44 (six in this embodiment) fixed along the frame 43 in a state of facing obliquely downward are disposed, and the lower part of the frame 43 is disposed by the above-described transport device 13. The game board 2 passes through. When the game board 2 is transported below the frame 43, the control device 500 stops the transport apparatus 13 and images the entire game board 2 with the plurality of cameras 44. Then, the control device 500 integrates image data from the plurality of cameras 44 to specify the position (coordinates) of the head 200b of each obstacle nail 200, and also stores each obstacle nail 200 stored in the storage unit 502. It collates with the set position (designated position) of the head 200b and checks whether there is any deviation from the set position.

  As described above, in the first nail inspection device 17A, the whole is photographed from the periphery of the game board 2 by the plurality of cameras 44 facing obliquely downward, and the image data is integrated by the control device 500, and each obstacle nail is processed. In order to specify the position of 200, not only the front / rear / left / right positions (positions in the X and Y axes) of each obstacle nail 200 but also the height direction position (position in the Z axis) of each obstacle nail 200 It is possible to grasp, and the planting state of each obstacle nail 200 can be inspected with high accuracy.

  In the present embodiment, as an example of grasping the position of each obstacle nail 200, a mode in which each obstacle nail 200 is photographed by a plurality of cameras 44 has been described, but the present invention is not limited to this. For example, a sound wave sensor or an optical sensor may be used as long as the position of each obstacle nail 200 can be grasped.

  As described above, in the first inspection, the control unit 501 arranges the head 200b of each obstacle nail 200 within the allowable range of the set position based on the captured image captured by the camera 44 of the second nail inspection device 17B. On the other hand, in the second inspection, the head 200b of each obstacle nail 200 is placed within the allowable range of the specified position by the measurement unit 602 (force sensor) provided in the inspection tool 600. By determining whether or not it is done, the state of the obstacle nail 200 can be determined in more detail than in the first maintenance, so that maintenance with higher accuracy can be performed.

  Next, various data stored in the storage unit 502 of the control device 500 and a data setting method will be described with reference to FIGS. FIG. 14 is a diagram showing a two-dimensional code printed on a sticker and other information. FIG. 15 is a diagram illustrating an interface displayed when referring to the model registration information list stored in the storage unit. FIG. 16 is a diagram showing an interface displayed when model registration information is newly registered in the storage unit. FIG. 17 is a diagram illustrating an interface displayed when setting maintenance data of each specific obstacle nail. FIG. 18 is a diagram illustrating an interface displayed when setting navel maintenance data. FIG. 19 is a diagram showing an interface displayed when setting maintenance data for an arbitrary nail. In the following, an interface displayed on a display (not shown) connected to the control device 500 will be described.

  As shown in FIG. 15, the storage unit 502 stores a plurality of model registration information in advance. This model registration information includes the item code that is the type of game board 2, material (plywood or synthetic resin), nail position accuracy, nail height accuracy, windmill nail position accuracy, windmill nail height accuracy, maintenance nail position accuracy (Designated nail position accuracy), maintenance nail height accuracy (designated nail height accuracy), camera setting file, etc. are registered. The nail position accuracy, the nail height accuracy, the windmill nail position accuracy, the windmill nail height accuracy, the maintenance nail position accuracy, and the maintenance nail height accuracy described here are allowable error ranges (allowable ranges). Further, the types of the game board 2 are various, for example, the game board surface 2a is flat or undulated (3D specification), and the camera 44 described above according to the model of the game board 2 is used for the camera setting file. This is data for setting the shooting angle.

  Each item code stores a serial code (unique ID) given to the two-dimensional code 15a affixed to each game board 2, maintenance data, gauge data described later, and the like. Therefore, when the two-dimensional code 15a is read by the above-described two-dimensional code reader, the control device 500 extracts an item code corresponding to the read serial code, and stores operation pattern data of various devices stored in association with the item code. And gauge data are extracted, and based on the information, various apparatuses perform the operations in steps S3 to S7 described above.

  The interface for referring to the model registration information list is provided with a new addition button for newly registering model registration information in the storage unit 502. When this new addition button is selected, an interface for newly registering model registration information appears in the storage unit 502 as shown in FIG. When registering new model registration information in the storage unit 502, first enter an item code with a keyboard (not shown) or select an item code from a list of item codes (not shown) by pressing the automatic input button. And input. Next, gauge data, which is a unique nail arrangement assigned according to the model of the game board 2, is input. The gauge data is inputted by selecting the corresponding gauge data from a gauge data list (not shown) by pressing the reference button. After that, the above-mentioned camera setting file and various nail accuracy are input. In addition, the new registration interface includes buttons for setting the correct driver maintenance data for the nail maintenance and the maintenance direction and angle of the optional nail.

  When the correct driver maintenance data setting button is selected, an interface for setting accurate driver maintenance data appears as shown in FIG. This interface includes accurate information such as maintenance location (type of designated nail), nail number, center position X, Y (coordinate data of head 200b), approach direction of maintenance tool 400, maintenance data (motion pattern data), etc. A driver list and a gauge data image (see the lower part of FIG. 17) are displayed. The designated nails can be set by inputting the above-described designated nails 204 to 208 or the like into the maintenance locations (types of designated nails) displayed on this interface.

  In the maintenance data column in the accurate driver list, one operation pattern data can be selected from a plurality of operation pattern data by a pull-down method, and the nail number, center position X, Y (head 200b Coordinate data) and the approach direction of the maintenance tool 400 can be set.

  The correct driver list has buttons for navel setting, chucker setting, passing gate setting, triangle setting, etc. By selecting an arbitrary button, the maintenance location associated with the button is accurate. Selected in the driver list. When an arbitrary maintenance location is selected from this exact driver list (in the present embodiment, navel nails are selected), the area around the obstacle nail 200 selected in the gauge data image is colored, and which maintenance location the operator has selected. It is easy to grasp. In this embodiment, when an arbitrary maintenance location is selected from the exact driver list, the area around the obstacle nail 200 selected in the gauge data image is colored. However, the present invention is not limited to this. If it is easy to grasp whether or not the failure nail 200 is selected, the periphery of the failure nail 200 selected in the gauge data image or the failure nail 200 itself may be lit or blinking.

  When an operation such as double-clicking is performed in a state where an arbitrary maintenance location is selected in the accurate driver list, as shown in FIG. 18, for maintenance data setting of an arbitrary maintenance location (in this embodiment, navel). An interface appears. In this interface, a nail swing angle, a nail swing movement amount, a Z-axis direction movement amount, a stop time, and a nail swing speed can be set for each maintenance data (operation pattern data). As described above, since various maintenance data (operation pattern data) can be set for each maintenance location (type of designated nail), settings for setting a specific obstacle nail 200 to a desired planting state are possible. Convenient.

  Further, when the button for setting the maintenance direction and angle of the arbitrary nail is selected in the above-described new registration interface, an interface for setting the maintenance direction and angle of the arbitrary nail appears as shown in FIG. . This interface includes a list of registered nail numbers, center positions X and Y (coordinate data of the head 200b), height, direction, angle, driver type (maintenance tool type), etc., and gauge data image (Refer to the lower part of FIG. 18). In the gauge data image in this interface, a specific obstacle nail 200 is colored, and the obstacle nail 200 of the nail number selected in the registration list list is distinguished (in this embodiment, it is circled). The operator can easily grasp the obstacle nail 200 being selected. According to this, since it becomes possible to maintain every single failure nail 200 regardless of the type of the specific failure nail 200, the specific failure nail 200 can be more precisely maintained in a desired planting state. It can be done.

  As described above, the obstacle nail maintenance device 300 according to the embodiment of the present invention is to maintain the plurality of obstacle nails 200 provided on the game board surface 2a of the pachinko gaming machine 1, and includes a plurality of obstacle nails. The first maintenance performed in step S5 on the obstacle nail 200 whose deviation from a predetermined setting position out of the allowable range of 200 is out of the allowable range, and a failure nail designated in advance among the plurality of obstacle nails 200 (for example, The second maintenance performed in step S6 can be performed on the designated nails 204 to 208). In the second maintenance, maintenance different in content from the first maintenance is performed. In this way, in the first maintenance, it is possible to uniformly maintain the deviation from the set position for the plurality of obstacle nails 200, and in the second maintenance, the deviation maintenance for the previously designated obstacle nail is performed. Since the maintenance can be performed with different contents, detailed maintenance corresponding to the nail arrangement (gauge) of the obstacle nail 200 or the like is possible.

  The obstacle nail maintenance method as an embodiment of the present invention is a failure nail maintenance method for maintaining a plurality of obstacle nails 200 provided on the game board surface 2 a of the pachinko gaming machine 1. Step S5 of performing the first maintenance on the failure nail 200 whose deviation from the set position is outside the allowable range, and a failure nail designated in advance among the plurality of failure nails 200 (for example, designated nails 204 to 208). ) In which the second maintenance is performed, and in the process S6, the maintenance differs from the process S5. By doing so, in step S5, the deviation from the set position can be uniformly maintained for the plurality of obstacle nails 200, and in step S6, the maintenance of the deviation for the previously specified obstacle nail is the content. Therefore, it is possible to perform detailed maintenance according to the nail arrangement (gauge) of the obstacle nail 200 or the like.

  The obstacle nail maintenance system as an embodiment of the present invention includes a nailing machine 16 for driving a plurality of obstacle nails 200 into the game board surface 2a of the pachinko gaming machine 1, and a preset position for each of the plurality of obstacle nails 200. The first nail inspection device 17A and the second nail inspection device 17B that determine whether or not the deviation from the tolerance is within the allowable range, the failure nail maintenance device 300 that maintains the plurality of failure nails 200, and the nail driver 16 The control device 500 controls the first nail inspection device 17A, the second nail inspection device 17B, and the obstacle nail maintenance device 300. The control device 500 controls the plurality of obstacle nails 200 provided on the game board surface 2a. Obstacle nail designation means for designating a specific obstacle nail (for example, a maintenance location (type of designated nail) displayed on the interface for setting accurate driver maintenance data), and a nail maintenance device 3 First maintenance instruction means for instructing the execution of the first maintenance on the obstacle nail for which the deviation from the set position is determined to be outside the allowable range by the first nail inspection device 17A and the second nail inspection device 17B. For example, when the control unit 501 that has received the inspection result data has a displacement in the XY-axis direction with respect to the set position of the head 200b out of the allowable range due to the inspection in step S4 among the obstacle nails 200 driven in step S3. For the determined obstacle nail 200, first maintenance data for arranging the head 200b of the obstacle nail 200 within the allowable range of the set position is created, and the first maintenance data is transported to the game board 2 To the failure nail maintenance device 300 and instructing the failure nail maintenance device 300 to execute the second maintenance on the failure nail designated by the failure nail designation means. First Maintenance instruction means (e.g., the controller 501 targets the obstacle nail 200 (e.g., the designated nails 204 to 208) designated in advance according to the type of the game board 2 among the plurality of obstacle nails). The second maintenance data for placing the head 200b within the permissible range of the designated position to the obstacle nail maintenance device 300 and instructing the execution of the second maintenance). The maintenance will be different from the first maintenance. In this way, in the first maintenance, it is possible to uniformly maintain the deviation from the set position for the plurality of obstacle nails 200, and in the second maintenance, the deviation maintenance for the obstacle nail 200 designated in advance is performed. Therefore, detailed maintenance corresponding to the nail arrangement (gauge) of the obstacle nail 200 and the like can be performed.

  In addition, by performing the second maintenance after performing the first maintenance, the second maintenance can be performed in a state where the shift is maintained in the first maintenance, and therefore the second maintenance can be performed accurately.

  Further, first determination means for determining whether or not the deviation from the set position is within an allowable range for the obstacle nail 200 that has undergone the first maintenance (for example, the control unit 501 of the control device 500 performs the first maintenance). Whether or not the obstacle nail 200 after maintenance is inclined about 4 degrees upward with respect to the Z-axis direction orthogonal to the game board surface 2a is specified from the gauge data corresponding to the game board 2. A portion determined based on the positional deviation direction and the positional deviation amount in the XY axis direction with respect to the set position of the head 200b of each obstacle nail 200) and the designation specified in advance for the obstacle nail 200 that has undergone the second maintenance. Second determination means for determining whether or not the deviation from the position is within an allowable range (for example, the control unit 501 of the control device 500 determines that the head 200b of the designated nail 204 on which the second maintenance has been performed is at the designated position). Tolerance A portion for determining whether or not the first determination means is disposed), and the determination method by the first determination means and the determination method by the second determination means are different, so that the determination according to the contents of maintenance can be performed efficiently. Can do.

  Further, since the second determination means determines whether or not the deviation from the designated position is within the allowable range based on the measurement result using the force sensor, the state of the prepared obstacle nail 200 is detailed. I can grasp it.

  The force sensor has a first contact side 602L and a second contact side 602R arranged to intersect the first contact side 602R. The first contact side 602L and the second contact side The deviation from the predetermined designated position is within an allowable range due to a load applied when the first contact side 602L or the second contact side 602R is contacted while moving the base point RP with respect to 602R toward the designated position. Since it is determined whether or not there is, it is possible to grasp in detail the state of the prepared obstacle nail 200.

  In addition, in the first inspection, the control unit 501 determines whether the head 200b of each obstacle nail 200 is located within the allowable range of the set position based on the image captured by the camera 44 of the second nail inspection device 17B. Since a plurality of cameras 44 are fixed to the predetermined frame 43, the state of the obstacle nail can be grasped in detail.

  In addition, it has measurement means (for example, a hygrometer and a thermometer) that can measure the state of the outside air, and performs the first maintenance and the second maintenance based on the measurement result of the measurement means, so that the first maintenance and the second maintenance are performed. The accuracy of maintenance can be increased.

  Further, in the second inspection, the control unit 501 determines whether or not the head 200b of each obstacle nail 200 is disposed within the allowable range of the specified position by the measurement unit 602 (force sensor) provided in the inspection tool 600. From the game board surface 2a of the head 200b of the obstacle nail 200, the bending state of the obstacle nail 200 is specified from the amount of deviation in the XY-axis direction with respect to the specified position of the trunk portion 200a at each inspection point P1, P2. Therefore, the state of the obstacle nail 200 can be grasped in detail.

  Further, a clamping part 403 that can be arranged so as to sandwich the trunk part 200a of the obstacle nail 200, and operating means for operating the clamping part 403 (for example, the control unit 501 of the control device 500, the maintenance arm 301 of the obstacle nail maintenance apparatus 300). , A maintenance source of the maintenance arm 301, and the like, and operating the clamping part 403 by the operating means to maintain the obstacle nail in which the body part 200 a is sandwiched by the clamping part 403. Can move the holding part 403 in the XY-axis direction, which is a direction along the game board surface 2a, and the Z-axis direction, which is a direction orthogonal to the game board surface 2a. A first step in which the portion 200b is disposed at the first position, a second step in which the sandwiching portion 403 is tilted in one direction in the XY direction at the first position, and the sandwiching portion 403 is moved from the first position to the Z position. A third step of tilting in the other direction of the XY-axis direction as well as arranged in a second position away from the game board 2a than the first position is moved in a direction, which is capable of executing. By doing in this way, not only inclining the clamping part 403 to one direction of an XY axis but performing the operation | movement which returns to another direction can give force with sufficient balance with respect to the trunk | drum 200b. Further, after the clamping portion 403 arranged at the first position is tilted in one direction in the XY axis direction, the bending force is applied only to a part of the trunk portion 200b by moving it to the second position as well as returning to the other direction. Since concentrated action can be avoided, the trunk portion 200b can be stably maintained without being bent halfway.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.
