Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a game machine such as a pachinko machine, in which a nail is driven into a game board conforming to a standard.

Pachinko machine manufacturers cut the reference holes and guide rail mounting holes that are used to position the decorative sheet as a decorative board surface on one side of a game board such as a plywood board, and the post-process. Multi-axis drilling process, Gauge pressing process for punching holes for nails and game function components, Router process for cutting openings for game function components, and nails called game nails and obstacle nails The game board (gauge board) is manufactured through a nailing process for driving, an assembly process for mounting a guide rail and a game function component, an inspection process for checking whether the game function component operates normally, and the like. By the way, it is conceivable to suppress the occurrence of defective products by supplying only good game substrates whose warpage, outer shape, thickness, etc. are within the standard to the initial process. However, in the router process, a relatively large opening is formed in the game board consisting of the decorative sheet and the game board, and the internal stress in the game board changes, which may cause the game board to be warped out of specification. However, there is an inconvenience that even if a nail is driven into the warped game board, it becomes a defective product.

  The problem to be solved by the invention is that a non-standard warp may occur in the game board after the router process, and even if a nail is driven into the warped game board, it becomes a defective product.

  The method of manufacturing a gaming machine according to the present invention includes a router step of cutting an opening for mounting a game function component on a game board having a design board surface, and a nailing step of driving nails into the game board according to the model of the game board. A warp inspection step and a discharge step, wherein the warp inspection step electrically detects the warpage of the game board discharged from the router step and determines whether the detected warp is within a preset allowable range. If the warpage is small, it is determined that the game board is non-defective, and if the warp is out of the preset allowable range, the warpage is large and the game board is determined to be defective. The game board as a non-defective product is supplied to the nailing process based on the result of the determination that the game board is non-defective in the process, and the game board as the defective product is determined based on the result of the warpage inspection process determining that the game board is defective. The warp inspection process or Ri and most important feature to retrieve from between the inspection process and Kugida step.

  The method of manufacturing a gaming machine according to the present invention, 100% inspection of the warpage of the game board supplied from the router process to the nailing process, abolished the nailing to the game board in which the warpage of the non-standard occurred, a good game Executing nailing only on the board has an advantage in that production of defective products due to warpage in the nailing step and subsequent steps can be prevented, and the production efficiency can be improved. In the method for manufacturing a gaming machine according to the present invention, in the warp inspection step, a game board having an opening for mounting a game function component discharged from the router step arrives at the inspection position on a conveyor for transporting to a nailing step. The game board is mechanically levitated and supported from the conveyor, and the warpage of the game board is electrically detected by a sensor located corresponding to the unprocessed portion where there is no opening common to different models of the game board. While the board is mechanically transferred to the conveyor, if the warpage of the game board detected by the sensor is provided with a warpage inspection device for electrically determining the quality of the game at the processing unit, a game having an opening for mounting a game function component from the router process is provided. In the process of transporting the board to the nailing process, there is an advantage that 100% inspection can be performed automatically. In the manufacturing method of the gaming machine according to the present invention, in the discharging step, the conveyer is retracted in the direction intersecting with the transport direction according to the result of the determination that the game board is a defective product in the warp inspection step, and the defect is determined to be defective during that time. If a discharge device for dropping the approved game board is provided, the structure of the conveyor that conveys the game board having an opening for attaching the game function component from the router process to the nailing process is advanced in the direction intersecting the conveyance direction. By changing to retreat, it is possible to properly discharge the defective game board from the conveyor to the outside in the process of transporting the game board having the opening for attaching the game function component from the router process to the nailing process. There are advantages.

  1 to 4 show one embodiment. In FIG. 1, first, in a router step 1, a game board 5 in which a decorative sheet as a design board surface is joined to a game board through respective steps of a decorative sheet pasting step, a multi-axis drilling step, and a gauge press step, is provided. Cut the mounting opening. Next, in the warp inspection step 2, the warpage of the game board 5 is electrically detected, and if the detected warp is within a preset allowable range, the warp is small and the game board 5 is determined to be a good product. Conversely, if the warpage is outside the preset allowable range, the warpage is large and the gaming board 5 is determined to be defective. Then, in the discharging step 3, the game board 5 determined to be defective in the inspection step is taken out from the warp inspection step 2 or between the warp inspection step 2 and the nailing step 4. In the nailing step 4, a number of nails called game nails or obstacle nails are driven into the game board 5 determined to be non-defective in the warp inspection step 2 according to the model of the game board 5. That is, the warpage of the game board 5 is inspected prior to the nailing process 4, the nailing to the game board 5 in which the warpage of the non-standard has occurred is abolished, and the nailing is performed only for the good game board 5. In addition, the production efficiency can be improved by preventing the occurrence of defective products in the nailing step 4 and subsequent steps.

  In FIG. 2, an apparatus used for each of the warp inspection step 2, the discharge step 3, and the nailing step 4 will be described. The game board 5 that has passed through the router process 1 is a form in which a decorative sheet 5b that constitutes a design board surface is bonded to one surface of a game board 5a such as a plywood board. An opening 5c for attaching various game function parts such as a number ramp, a variable winning opening, an out opening, and the like, and a reference hole 5d for positioning work in each process are conveyed by the conveyor 6 in the conveying direction X. The conveyor 6 has a plurality of rollers 6b arranged in parallel in the transport direction X and rotatably mounted on a pair of conveyor frames 6a opposed to each other at a predetermined interval in a direction orthogonal to the transport direction X, and all or all of the rollers 6b are mounted. A guide rail 6c is provided on each of the conveyor frames 6a to guide the game board 5 in the transfer direction X on each conveyor frame 6a.

  The warp inspection device 11 in the warp inspection process 2 includes a lower fixed plate 11a laid and connected to a lower portion of the conveyor frame 6a, and a support 11b separated from the lower fixed plate 11a by a support 11b to be separated from an upper transport portion of the roller 6b. And an upper fixed plate 11c fixedly supported so as to be substantially parallel to the upper conveying portion, and a warp such as a magnet scale that outputs the amount of movement of the piston rod of the air cylinder to the upper fixed plate 11c by magnetoelectric conversion. And a plurality of sensors 11d for performing an inspection.

  As shown in FIGS. 3A and 3B, in this embodiment, each sensor 11d has four intersections B between a diagonal line L1, L2 of the upper fixed plate 11c and a circle L3 centered at the center point A. The upper fixed plate 11c is provided on the upper fixed plate 11c so as to correspond to an unprocessed portion common to different models of the game board 5 in which holes or openings of the game board 5 are not formed, such as c, d, and e. A piston rod as a child 11e penetrates the lower surface of the upper fixed plate 11c at four intersections B to E. The upper fixed plate 11c includes three upper support pins 11f serving as measurement references, a plurality of positioning protrusions 11g, a horizontal pusher 11h, and a vertical pusher 11j. Each upper support pin 11f is opposed to two intersections of a circle L4 concentric with the circle L3 and having a radius smaller than the circle L3 and the diagonal lines L1 and L2, and a center point A between these intersections. Each of the intersections of the bisecting line L5 and the circle L4 of the included angle by the diagonal lines L1 and L2 is provided on the side, and the lower surface as each measurement reference surface is formed in parallel with the upper conveying portion of the roller 6b. The positioning protrusion 11g is located on the front side in the transport direction X, and is located at a front edge of the upper fixed plate 11c and equidistant to the left and right from the center point A of the upper fixed plate 11c, and at one side in the transport direction X. At a total of three places, that is, one side edge of the located upper fixing plate 11c and a position adjacent to the front edge, the lower end protrudes from the lower surface of the upper fixing plate 11c. The horizontal pusher 11h is formed by an air cylinder and is provided on the lower surface of the upper fixed plate 11c so that the pressing element 11i attached to the tip of the piston rod faces the positioning projection 11g on one side in the transport direction X. I have. The vertical pusher 11j is formed by an air cylinder and the lower surface of the upper fixed plate 11c so that the pressing element 11k attached to the tip of the piston rod is located at the center between the left and right positioning projections 11g on the front side in the transport direction X. It is provided in. The transport stopper 11m is disposed on the lower fixed plate 11a so as to be located on the upstream side in the transport direction X from the positioning protrusion 11g on the front edge side of the upper fixed plate 11c. The transport stopper 11m is an air cylinder (not shown) attached to the lower fixed plate 11a and moves up and down above and below the upper transport section through a gap between a pair of rollers 6b.

  In FIG. 3B, the lift base 11n disposed between the lower fixed plate 11a and the conveyor 6 is raised in two steps by a double cylinder 11p installed on the lower surface of the lower fixed plate 11a. On the other hand, during the elevating operation of the double cylinder 11p, the double cylinder 11p is slidably engaged with a guide mechanism (not shown) provided on the lower fixed plate 11a so as not to be swung in the horizontal direction. On the lift base 11n, a lower support pin 11q is erected so as to be vertically coaxial with the upper support pin 11f of the upper fixed plate 11c. The upper surface of each lower support pin 11q forms a support surface parallel to the lower surface of the upper support pin 11f. When the lift base 11n is stopped at the lower limit position, each lower support pin 11q is positioned below the upper transport section of the roller 6b so as not to interfere with the game board 5 transported on the roller 6b, The gaming board 5 is lifted from the rollers 6b through the gap between the rollers 6b by the raising operation of the base 11n, and is supported so as to be sandwiched between the upper supporting pins 11f.

  In the warpage inspection device 11, one game board 5 is conveyed by the conveyor 6 and arrives between the upper fixed plate 11c and the lower fixed plate 11a, and the front edge of the game board 5 is higher than between the rollers 6b. After coming into contact with the projecting transport stopper 11m, the transport operation of the conveyor 6 is interrupted. The transfer stopper 11m hinders the transfer of the game board 5 after the transfer operation of the conveyor 6 is interrupted and before the game board 5 is transferred to the next process side by resuming the transfer operation of the conveyor 6 described later. In order to prevent this, the roller 6b descends below the upper conveying section. Then, after the double cylinder 11p is extended and driven to the first stage, the lower support pin 11q rises from the lower limit position together with the lift base 11n, and lifts the game board 5 above the guide rail 6c of the conveyor 6. Then, the first-stage extension drive of the double cylinder 11p stops, and the lift base 11n stops at the first ascent stop position. In the first ascent stop position, as shown in FIG. 3C, the side surface of the game board 5 is located between the positioning protrusion 11g, the horizontal pusher 11h, and the vertical pusher 11j, and the upper surface of the game board 5 is located on the upper side. It is in a state of not contacting the support pin 11f. Thereafter, the presser 11i of the horizontal pusher 11h and the presser 11k of the vertical pusher 11j press the game board 5 toward the positioning protrusion 11g, whereby the game board 5 is positioned with the positioning protrusion 11g as a reference. The center of the board 5 is arranged substantially coaxially with the center point A of the upper fixed plate 11c.

  Subsequently, the double cylinder 11p is extended and driven to the second stage to raise the lower support pin 11q again from the first raising / stopping position to further raise the game board 5, and then to move the double cylinder 11p to the second stage of the double cylinder 11p. The extension drive stops, and the lift base 11n stops at the second ascent stop position. At the second stop position, as shown in FIG. 3D, the game board 5 is supported at three points so as to be sandwiched between the upper support pin 11f and the lower support pin 11q. Then, the tracing stylus 11e of each sensor 11d moves down and comes into contact with the upper surface of the game board 5, and each sensor outputs an electric signal corresponding to the descending amount to an electric processing unit 11r having a built-in computer shown in FIG. After that, the tracing stylus 11e moves up to return to the original position, and the pusher 11i of the horizontal pusher 11h and the pusher 11k of the vertical pusher 11j return to the original position. The lower support pin 11q stops together with the lift base 11n and stops at the lower limit position from the second ascending stop position together with the lower support pin 11q without being temporarily stopped at the stop position. During this lowering, the game board 5 is mounted on the rollers 6b from between the guide rails 6c of the conveyor 6. Then, the conveyor 6 restarts the transport operation and transports the game board 5 in the transport direction X shown in FIG. 2 toward the next step.

  On the other hand, the processing unit 11r converts the output from each sensor 11d into a difference from the reference surface at each of the measurement points B to E, that is, the tip of the tracing stylus 11e is the same as the lower surface that is the reference surface of the upper support pin 11f. The movement amount located in the plane is defined as a zero point (reference), the displacement amount due to the warpage of the game board 5 is calculated from the zero point at each of the measurement points B to E, and the difference as each calculation result is a preset tolerance. If the value is out of the range, it means that the warp is large and the use is hindered. Therefore, the game board 5 is determined to be defective, and a fault signal for removing the game board 5 out of the conveyor 6 is generated. On the other hand, if the difference between the calculation results is within a preset allowable range, it means that the warpage is small and it is safe to use the game board 5, so that the gaming board 5 is determined to be good. Therefore, the defective signal does not occur.

  In short, according to the warpage inspection device 11, when the game board 5 conveyed by the conveyor 6 arrives just above the lower fixed plate 11a, the game board 5 is stopped by the conveyance stopper 11m at the upper limit position. After that, the conveying operation of the conveyor 6 is stopped, the lift base 11n is raised, the gaming board 5 is supported by the lower support pins 11q so as to float above the conveyor 6, and is supported at three points so as to be sandwiched between the upper support pins 11f. After the processing unit 11r converts the outputs from the four-point sensors 11d into differences from the reference plane at each of the measurement points B to E and detects the warpage of the game board 5, the lift base 11n is supported on the lower side. By lowering the pins 11q so as to be lower than the upper conveying portion of the conveyor 6, and transferring the game board 5 to the conveyor 6 during the lowering, the warpage of the game board 5 can be automatically checked. In addition, by arranging the sensors 11d at the four intersections B to E corresponding to unprocessed portions common to different models of the game board 5 supported by flying, the number of the sensors 11d is minimized and detected. Accuracy can be improved. The reason is that when the game board 5a of the game board 5 is a plywood board, the plywood board is composed of a plurality of layers of superficial wood fibers and lower wood fibers constituting the veneer board, which are overlapped in a multi-stage manner. This is because the corners are more prominent than the center of the four sides.

  Returning to FIG. 2 again, the discharging device 12 in the discharging step 3 includes a pair of transport mechanisms 12 a arranged so as to be continuous with the downstream side of the conveyor 6. The transport mechanism 12a is configured such that the fixed bases 12b are arranged to face each other at a predetermined interval in a direction orthogonal to the transport direction X, and a direction orthogonal to the transport direction X by an actuator 12c such as an air cylinder attached to each fixed base 12b. A plurality of rollers 12e are arranged in a line in the transport direction X and rotatably mounted on the inner surface of a movable plate 12d that moves forward and backward, and the power of a motor (not shown) is applied to each roller 12e by a rubber belt 12e-1 (see FIG. 4). (See FIG. a)), and the rollers 12e are electrically driven to convey the game board 5 unloaded from the conveyer 6 via the warpage inspection device 11 in the conveying direction X. An inner side surface of the movable plate 12d protruding above each roller 12e serves as a guide portion for guiding the game board 5 conveyed by the rollers 12e in the conveying direction X. The fixed base 12b includes a substrate stopper 12f and a delivery mechanism 12h.

  The board stopper 12f is retracted from the transfer path of the game board 5 by the transfer mechanism 12a by the actuator 12g such as an air cylinder attached to the fixed base 12b while the warpage inspection device 11 does not detect the failure of the game board 5. As described above, the game board 5 is stopped at the retreat limit position, the conveyance of the game board 5 is continued, the warpage inspection device 11 detects a defect of the game board 5, and the game board 5 detected as defective is transferred to the conveyance mechanism 12a. At this time, the transport of the game board 5 is forcibly stopped by being stopped at the forward limit position by the actuator 12g so as to advance from the retreat limit position and protrude onto the transport path of the game board 5.

  The delivery mechanism 12h corrects the falling attitude of the game board 5 that falls from between the transport mechanisms 12a by retreating the movable plate 12d to a horizontal plane similar to the transport attitude of the transport mechanism 12a. A receiver 12j provided so as to be able to move forward and backward in the same direction as the movable plate 12d of the transport mechanism 12a by an attached actuator 12i such as an air cylinder, and a stationary portion such as a casing of an actuator 12i near the receiver 12j. A notch 12m formed in the movable body between the pair of rollers 12e of the transport mechanism 12a while the warpage inspection device 11 is provided with the attached abutting rod 12k and the warpage inspection device 11 detects no defect in the game board 5. The game board 5 is stopped at the further backward limit position, the warpage inspection device 11 detects a defect of the game board 5, and the game board 5 detected as defective is transferred to the transport mechanism 12a. When the receiver 12j is stopped at the forward limit position via the notch 12m of the transport mechanism 12a, the horizontal piece of the receiver 12j is positioned on the roller 12e of the transport mechanism 12a. The vertical piece of the receiving body 12j approaches the front and rear side surfaces of the game board 5 in close proximity. Then, after the movable plate 12d of the transport mechanism 12a retreats and the game board 5 which falls from between the rollers 12e is mounted on the horizontal piece of the receiver 12j, the receiver 12j stops at the retreat limit position. The interval between the horizontal pieces of the receivers 12j facing each other in the front-rear direction is set to be larger than the width of the game board 5, and the game board 5 falls from between the receivers 12j facing in the front-rear direction. The front end of the abutting rod 12k is substantially flush with the inner surface of the movable plate 12d so as to face the front and rear side surfaces of the game board 5 at the notch 12m of the movable plate 12d stopped at the forward limit position of the transport mechanism 12a. And does not interfere with the game board 5 transported by the transport mechanism 12a. Further, the tip of the abutting rod 12k protrudes inward from the notch 12m of the movable plate 12d when the transport mechanism 12a stops at the retreat limit position, and when the receiver 12j stops at the retreat limit position, the game board 5 Is prevented from being accompanied by the receiver 12j, and the game board 5 is dropped in a horizontal plane without tilting from the receiver 12j.

  In the discharge device 12, when the movable plate 12d of the transport mechanism 12a is stopped at the forward limit position and the transport mechanism 12a can take over the game board 5 from the conveyor 6 and transport the game board 5, the warp detecting device 11 detects a defect. When the game board 5 as a defective product from which the signal is output and the defect detection signal is output is transferred from the conveyor 6 to the transfer mechanism 12a as shown in FIG. The stopper 12f regulates the conveyance of the game board 5. Next, as shown in FIG. 4B, the receiver 12j of the delivery mechanism 12h moves forward and sinks below the front and rear direction of the game board 5 above the rollers 12e. Thereafter, as shown in FIG. 4C, the movable plate 12d retreats, the roller 12e escapes from the game board 5, and the game board 5 is supported by the receiver 12j. Subsequently, the receiver 12j retreats. At the time of retreat, since the abutment rod 12k corresponds to the front and rear side surface of the game board 5, even if the game board 5 tries to accompany the receiver 12j, the game board 5 abuts on the abutment rod 12k. The game board 5 is thereby prevented from tailgating, and the game board 5 drops from the receiver 12j while maintaining a horizontal plane. Thereafter, the movable plate 12d of the transport mechanism 12a stops at the forward limit position from the backward limit position, and returns to the normal state in which the game board 5 from the conveyor 6 is transported in the transport direction X. In this normal state, the substrate stopper 12f stops at the retreat limit position and retreats from the transport path of the game board 5.

  In short, according to this discharge device 12, when the game board 5 determined to be defective is transferred from the conveyor 6 to the transport mechanism 12a and received by the board stopper 12f and stopped, the receiver 12j of the delivery mechanism 12h is moved to the game board 5 Dive below. Then, when the movable plate 12d of the transport mechanism 12a retreats, the game board 5 drops from between the front and rear directions of the rollers 12e of the transport mechanism 12a and is received by the receiver 12j. Thereafter, when the receiver 12j retreats and the game board 5 falls from the front-rear direction of the receiver 12j, the abutting rod 12k of the delivery mechanism 12h prevents the tailgating with the receiver 12j of the game board 5 from occurring. The game board 5 can be dropped horizontally.

  The falling game boards 5 are stacked in a block by a lift mechanism (not shown) provided below the transport mechanism 12a, or formed diagonally downward by a shooter (not shown) provided below the transport mechanism 12a. It is possible to slide down.

  Further, in FIG. 2, the nailing device 13 in the nailing process 4 is disposed on a pair of chain conveyors 13 a facing each other at a predetermined interval in the front-rear direction orthogonal to the transport direction X, and on the side of the chain conveyor 13 a. With a nailing machine 13b, and transports the good game board 5 via the discharging device 12 in the transport direction X by the chain conveyor 13a, and the game board 5 is located at a position corresponding to the table 13c of the nailing machine 13b. Is reached, the conveyance of the game board 5 is regulated by a board stopper (not shown), and the stopped game board 5 is transferred and mounted on the table 13c by a carry-in loading mechanism (not shown). The game board 5 is positioned and mounted on the table 13c with the reference holes 5d circumscribing the positioning pins 13d provided on the table 13c. Either a game board sensor (not shown) that detects that the game board 5 is positioned and mounted, or a manual switch (not shown) that is turned on by an operation of an operator in place of the game board sensor, By outputting the type signal and the nailing start signal to a control unit (not shown) in which the computer is built, the computer stores nailing data corresponding to the model of the game board 5 stored in advance in a storage device of the control unit. The nail driving positions and the order are extracted, and the table 13c is moved in the X direction and the Y direction as the vertical and horizontal directions in the plane according to the driving positions and the order, so that the predetermined position of the game board 5 is determined. The positioning stops below the nail holder mechanism (not shown) and the hammer mechanism (not shown) attached to the set plate 13e above it. Then, the nails (not shown) supplied to the nail holder mechanism from the nail supply unit 13f such as a parts feeder are driven into the game board 5 by a hammer mechanism, whereby a large number of nails to be hit on one game board 5 are obtained. The game boards 5 are automatically driven one by one. Next, when the driving of the predetermined number of nails is completed, the gaming board 5 into which the nails are driven by the unloading loading mechanism (not shown) is removed from the table 13c, and is transferred and mounted on the chain conveyor 13a or the unloading conveyor (not shown). Convey to the next step.

  In the nailing machine 13b, the case where the set plate 13e is stationary and the table 13c is driven has been illustrated and described, but the table 13c is stationary and the set plate 13e is driven so that the nail holder mechanism and the hammer mechanism can be connected. The same operation can be performed by moving the set in the X and Y directions or moving the table 13c in the X direction and moving the set of the nail holder mechanism and the hammer mechanism in the Y direction using the set plate 13e. In this case, if the nail supply unit 13f is mounted on the set plate 13e and moved in the same manner as the set including the nail holder mechanism and the hammer mechanism, the operation of supplying nails to the nail holder mechanism becomes smooth.

  As shown in FIGS. 5 and 6, as the warpage inspection device 11, a sensor 15 such as a proximity sensor, a photoelectric sensor, or a limit switch, which reacts when wood or a synthetic resin is present in a measurement range, is fixed on an upper side. A plurality of upper and lower sensors 15 are turned on or off in a state where a plurality of upper and lower support pins 11f and 11q support the upper and lower support pins 11f and 11q, as shown in FIG. It is determined that there is no warpage in the gaming board 5 if any one of the same operation states, and as shown in FIG. A double-sided inspection for judging that the board 5 is warped is also possible. In this case, the presence / absence of warpage is detected depending on whether the on / off operation of the upper and lower sensors 15 is the same or opposite, so that the displacement from the reference point, the difference between the displacement and the reference point, and the difference are acceptable. It is not necessary to electrically process whether or not it is included in the range, and the device can be simplified.

  As shown in FIG. 7, the warpage inspection device 11 is provided with a shaft 16 coaxially spaced above a center point a of either the upper fixed plate 11c or the lift base 11n. When the sensor 11d or the sensor 15 is mounted on the tip of the arm 17 that protrudes from the game board 5, and the shaft 16 is electrically driven to rotate, the sensor 11d or the sensor 15 is rotated with respect to the game board 5. Warping can be detected by 11d or one sensor 15.

  Further, the sensor 11d can be similarly applied to a non-contact type using light such as a laser or an LED.

  In the above-described embodiment, the warpage of the game board 5 is electrically detected. However, when the game board 5 is supplied to the nailing process 4, it is detected whether the game board 5 is warped artificially. The same applies to the case where the game board 5 of a defective product having an out-of-specification warp is not supplied to the nailing step 4 and only the game board 5 as a non-defective product is supplied to the nailing step 4.

  Further, in the above-described embodiment, the defective board 5 is automatically ejected from the process of transporting to the nailing step 4 in accordance with the result of the warp detection. In addition, an alarm such as a sound, an image, a sound, or the like is generated, and the alarm can be used to artificially discharge defective products.
