A lower second reference hole 10b having a diameter slightly larger than 109b passes through the front and back surfaces.

  FIG. 4 shows an outline of the router processing machine. The router processing machine 2 is an apparatus capable of drilling four game boards 10 simultaneously. The main body 2a has four tool heads 2b and chucks the cutting tool 2c.

  Below each tool head 2b, there is a fixing base 2d for fixing the game board 10 to be processed, and the gaming board 10 fixed through the floor plate 2h is drilled with a cutting tool 2c.

  The four fixed bases 2d, 2d, 2d, 2d are fixed to the work table 2e. The work table 2e can be moved horizontally with respect to the main body 2a in the direction of the arrow shown in FIG. 4A by an actuator or the like (not shown), and each fixed table 2d is positioned vertically below each tool head 2b. There are two states: a processed state and a standby state protruding from the main body 2a. When drilling the game board 10 fixed to the floor plate 2h attached to the fixed base 2d, the work table 2e is set in the processing state, and when exchanging the game board 10 to be drilled, the work board 10 2e enters a standby state. FIG. 4A shows a standby state.

  The four tool heads 2b, 2b, 2b, 2b are installed on the main body 2a so as to be vertically movable by an actuator (not shown). When the work table 2e is in a standby state, the tool heads 2b, 2b, 2b, 2b move upward and wait. Further, when the work table 2e is in the machining state, the work table 2e moves downward, and the cutting tool 2c can drill the game board 10.

  Further, the four tool heads 2b, 2b, 2b, 2b are attached to be horizontally movable by an actuator (not shown) or the like, and the work table 2e is attached to be horizontally movable back and forth by an actuator (not shown) or the like. Then, in accordance with a command from the NC controller 2i (see FIG. 2) attached to the router machine 2, the router machine 2 horizontally moves the four tool heads 2b, 2b, 2b, 2b and the work table 2e. Then, the gaming board 10 fixed on the fixed base 2d is drilled.

  In addition, a floor plate 2h having an opening larger than the hole to be machined in the game board 10 is detachably attached to each fixed base 2d by attachment means (not shown). The game board 10 is fixed to the upper surface of the floor board 2h.

  In the floor board 2h, a plate-shaped member having the same shape as the game board 10 to be drilled has an opening having a shape larger than the hole to be processed in the game board 10 in advance. The floor board 2h can be exchanged according to the shape of the hole to be processed in the game board 10.

  Further, an upper positioning pin 2h1 protrudes from the upper surface of the floor plate 2h on the side closer to the work table 2e, and a lower positioning pin 2h2 projects from the rear side of the work table 2e. When the game board 10 is placed on the floor board 2h so that the surface is down, the upper first reference hole 10a (see FIG. 3A) of the game board 10 and the upper positioning pin 2h1 are engaged. The lower second reference hole 10b (see FIG. 3A) of the game board 10 and the lower positioning pin 2h2 are engaged.

  As described above, the upper first reference hole 10a of the game board 10 and the upper positioning pin 2h1 are engaged, the lower second reference hole 10b of the game board 10 and the lower positioning pin 2h2 are engaged, and the floor plate Position the game board 10 in 2h. Therefore, the upper positioning pin 2h1 and the lower positioning pin 2h2 are in a positional relationship equivalent to the positional relationship between the first reference hole 10a and the lower second reference hole 10b in the game board 10, and the gaming board 10 Is placed so that the processing reference position of the router processing machine 2 coincides with the processing reference position of the game board 10 (see FIG. 2A).

  In this way, by using the replaceable floor plate 2h corresponding to the game board 10 to be processed, the shape of the hole to be processed in the game board 10 is not limited, and the router processing machine 2 is capable of drilling various shapes. It becomes possible to respond.

  FIG. 4B is a diagram showing the fixing base in a state where the floor plate is removed. Each fixed base 2d has an escape hole 2g that is larger than the hole processed in the game board 10 and leads to the work table 2e. And in the opening part of the escape hole 2g, it has the 1st holding means 20 which hold | maintains the remaining material 12 (refer FIG.4 (d)) produced by drilling.

  Further, as shown in FIG. 4 (b), a rotating shaft 2f2 that is rotatably attached by a rotating means (not shown) around the fixed table 2d toward the upper side of the work table 2e, Four fixing members 2f each including a pressing portion 2f1 attached to the rotating shaft 2f2 in a direction perpendicular to the rotating shaft 2f2 are provided. FIG. 4B shows a state in which the floor plate 2h is removed from the fixing base 2d for the sake of explanation.

  When the work table 2e is in a processed state, as shown in FIG. 4C, the pressing portion 2f1 of the fixing member 2f faces the fixing table 2d and is fixed to the pressing portion 2f1 and the fixing table 2d (not shown). The game board 10 is fixed by sandwiching the game board 10 with the floor board 2h (see FIG. 4A). In addition, (c) of FIG. 4 has also shown the state which removed the baseplate 2h from the fixed stand 2d for description.

  On the other hand, when the work table 2e is in the standby state, as shown in FIG. 4 (b), the pressing portion 2f1 of the fixing member 2f rotates so as to be substantially parallel to the side of the fixing table 2d. Is fixed to the fixed base 2d, and the game board 10 can be replaced.

  The remaining material 12 is a portion that is cut out from the game board 10 when the router machine 2 drills the game board 10. As shown in FIG. 4 (d), when the router processing machine 2 drills the game board 10, the cutting tool 2c moves around the periphery of the hole to be processed and corresponds to the opening of the hole to be processed. A hollow portion is formed. Then, the hollow portion is cut out from the game board 10 to generate a remaining material 12.

  The cut remaining material 12 is held by the first holding means 20 inside the escape hole 2g opened in the fixing base 2d.

  Although not shown, if a dust-proof cover is attached around each tool head 2b and the dust-proof cover is connected to a suction dust collector (not shown) via a dust-collecting duct, etc., this occurs during drilling. The dust can be collected in a suction dust collector without scattering.

  The escape hole 2g opened in the fixed base 2d communicates with the opening of the floor plate 2h, so that when the dust is sucked by a suction dust collector (not shown), the escape plate 2d of the fixed base 2d is passed through the escape hole 2g. Since a flow path of air passing through the opening of 2h to the dust collector is secured, the dust collector can effectively suck dust.

  Further, since the opening of the floor plate 2h penetrates to the escape hole 2g opened in the fixed base 2d, dust such as chips that are generated during drilling and are not collected by a suction dust collector (not shown). Then, it passes through the opening of the floor plate 2h and falls into the escape hole 2g opened in the fixed base 2d. As described above, the dust generated by the drilling process falls into the escape hole 2g opened in the fixed base 2d, so that the dust can be collected in the escape hole 2g without being scattered.

  FIG. 5 shows a schematic diagram of the first holding means. 5A is a perspective view of the first holding means, FIG. 5B is a view showing that the remaining material is held by the first holding means, and FIG. 5C is a view shown in FIG. ) Is a cross-sectional view taken along the line A-A in FIG. 4, and shows a state of the first holding means when in the processed state, and FIG. 4D is a cross-sectional view taken along the line A-A in FIG. It is a figure which shows the state of the 1st holding means at the time of completion | finish of drilling.

  As shown in FIG. 5 (a), the first holding means 20 is fixed to the bottom of a relief hole 2g (see FIG. 4 (b)) that opens to the work table 2e from the fixed table 2d. The remaining material holding base 20b that can be moved up and down by the vertical movement means 20a such as an actuator, and the remaining material holding head 20c provided on the remaining material holding base 20b so as to protrude upward. The first holding means 20 can be moved up and down by the vertical movement means 20a. For example, when the first holding means 20 is not used, the fixing pin 20d described later does not contact the game board 10. Can be lowered.

  The remaining material holding head 20c has a flat upper surface to form a remaining material holding surface 20e, and holds the cut remaining material 12 with the remaining material holding surface 20e as shown in FIG. 5B. To do.

  Also, the remaining material holding base 20b is provided with two fixing pins 20d and 20d, and the tip of each fixing pin 20d is positioned higher than the remaining material holding surface 20e. Then, the remaining material 12 held on the remaining material holding surface 20e is prevented from being displaced by engaging with an engagement hole 12a provided in advance in a portion that is cut from the game board 10 and becomes the remaining material 12. . Further, it is assumed that the engagement hole 12a is previously drilled in a portion that becomes the remaining material 12 in the multi-axis drilling process 202 shown in FIG.

  As shown in FIG. 5C, the remaining material holding head 20c is set so that the remaining material holding surface 20e and the upper surface of the floor plate 2h have substantially the same height. When the game board 10 is placed on the floor board 2h, the game board 10 is protruded from two engagement holes 12a and 12a that are previously drilled at positions where the game board 10 becomes the remaining material 12 and the remaining material holding base 20b. The two fixing pins 20d and 20d are engaged.

  And the part which the cutting tool 2c moved and cut | disconnected the periphery of the hole drilled in the game board 10 is hold | maintained as the remaining material 12 as shown in FIG.5 (d).

  In this way, the game board 10 and the remaining material 12 will be described later because the game board 10 fixed to the floor board 2h and the remaining material 12 held on the remaining material holding surface 20e are at the same height. The work hand 8 (see FIG. 9A) can be simultaneously carried out from the router processing machine 2.

  Next, (a) of FIG. 6 is a view showing the structure of the vertical conveyance path constituting the member supply path 4a and the member carry-out path 4b shown in FIG. 2, and (b) is an inclination of the vertical conveyance path. It is sectional drawing which shows this.

  As shown in FIG. 6A, the vertical transport path 4 is composed of two upper and lower rails laid in parallel at substantially the same interval as the height of the game board 10 to be transported. A plurality of transport rollers 40 a, 40 a, 40 a,... Are rotatably attached to the lower rail 40 in the lengthwise grooves provided wider than the thickness of the game board 10. The plurality of transport rollers 40a, 40a, 40a,... Are rotated in a fixed direction by a rotational power means such as a motor (not shown) and a rotation transmission means such as a chain belt (not shown).

  The conveyance roller 40a has a shape having flanges 40a2 and 40a2 at both ends of a cylindrical conveyance unit 40a1, and the interval between the two flanges 40a2 and 40a2 is set wider than the thickness dimension of the game board 10. And the game board 10 is conveyed by rotation of the conveyance roller 40a, while a lower end part fits into the conveyance part 40a1, and position shift is suppressed by the flange 40a2.

  A plurality of guide rollers 41a, 41a, 41a,... Are attached to the upper rail 41. The guide roller 41a is a disk-shaped roller, and is attached so as to be rotatable around a rotation shaft provided downward from the upper rail 41. And it is preferable that the circumferential part of the guide roller 41a protrudes to the conveying surface side from the end part of the upper rail 41.

  The vertical conveyance path 4 is configured by laying the upper rail 41 and the lower rail 40 configured in parallel as described above, and the vertical conveyance path is formed by the conveyance portion 40a1 of the conveyance roller 40a and the circumferential portion of the guide roller 41a. 4 conveyance surfaces are formed.

  In consideration of the stability when the game board 10 is transported in the vertical transport path 4, it is preferable that the transport surface is slightly inclined with respect to the vertical so that the transport surface faces upward, as shown in FIG. ), The upper rail 41 and the lower rail 40 are preferably laid at a position slightly deviated from the vertical. As described above, by slightly tilting the transport surface with respect to the vertical, the game board 10 is supported while applying a load to the guide rail 41a, and stability during transport is improved.

  Using the vertical conveyance path 4 configured as described above, a member supply path 4a and a member carry-out path 4b are formed.

  FIG. 7 is a diagram showing a form of laying the member supply path and the member carry-out path. As shown in FIG. 7 (a), in the present embodiment, the member supply path 4a and the member carry-out path 4b are on the upper side of the member supply path 4a, and the member carry-out path 4b is parallel to the member supply path 4a and is conveyed. It has a two-story structure with surfaces laid in the same direction. Then, the two rows of the two-story structure member supply path 4a and the member carry-out path 4b were laid so that the conveyance surfaces face each other. In other words, as shown in FIG. 7B, there are two rows of member supply paths 4a and two rows of member carry-out paths 4b.

  Then, as shown in FIG. 7B, the router processing machine 2 is installed facing the conveyance surfaces of the member supply path 4a and the member carry-out path 4b. The router processing machine 2 faces the respective conveying surfaces of the two rows of the member supply path 4a and the member carry-out path 4b, and is installed at a position where the respective router processing machines 2 face each other.

  In the member supply path 4a, the work hand 8 supplies the game board 10 to the router processing machine 2 (hereinafter referred to as a router supply point), and in the member carry-out path 4b, the work hand 8 A sensor 40b (see FIG. 6B) for detecting the game board 10 is fixed at a position (hereinafter referred to as a router carry-out point) where the game board 10 is carried out from the router processing machine 2. The sensor 40b is a device for detecting the game board 10 and notifying the line control device 9 (see FIG. 2) of the detection of the game board 10, and is connected to the line control device 9 by a signal line (not shown). .

  The sensor 40b is not particularly limited, but as shown in FIG. 6 (b), for example, use of a photoelectric sensor including a pair of light emitting unit 40b1 and light receiving unit 40b2 is conceivable. The photoelectric sensor is a sensor that detects that an optical signal from the light emitting unit 40b1 to the light receiving unit 40b2 is blocked, and the light emitting unit 40b1 and the light receiving unit 40b2 are long at both ends of the lower rail 40 of the member supply path 4a. Install them so as to sandwich the vertical groove. And if the game board 10 is conveyed by the conveyance roller 40a between the light emission part 40b1 and the light-receiving part 40b2, the optical signal from the light emission part 40b1 to the light-receiving part 40b2 will be interrupted | blocked, and the game board 10 can be detected. .

  In the present embodiment, since one router processing machine 2 has four fixed bases 2d, each router processing machine 2 has four router supply points and router unloading points. Will have.

  As described above, by installing the sensor 40b at the router supply point, the line control device 9 can detect that the game board 10 has been transported to the router supply point. Further, by installing the sensor 40b at the router carry-out point, the line control device 9 can detect that the game board 10 has been carried out from the router processing machine 2 to the member carry-out path 4b.

  Further, the member supply path 4a and the member carry-out path 4b are transport paths for transporting the game board 10 in the same direction, and are linearly formed from the starting point S that is the starting point of transport to the terminal end E that is the end point of transport. It is laid (see Fig. 2).

  By the way, as described above, a resin film called a cell is attached to the surface of the game board 10. Therefore, when drilling is performed by the router processing machine 2, the cutting tool 2c is applied from the back surface of the game board 10 so as not to damage the cell. Therefore, considering the efficiency when supplying the game board 10 to the router processing machine 2, in the member supply path 4a, the surface of the game board 10 is in contact with the conveying surface of the member supply path 4a so that the game board 10 is turned over. It is preferable to be conveyed.

  However, the transport conveyor C transports the game board 10 with rollers that are in contact with the entire surface. Therefore, when the game board 10 is transported in an inverted state, the cells attached to the surface of the game board 10 may be damaged. There is.

  In contrast, in the vertical transport path 4 according to the present embodiment, the game board 10 and the vertical transport path 4 are in contact with each other at the lower end of the game board 10 in contact with the transport roller 40a and the guide roller. It is only the upper end part of the game board 10 which contacts 41a. And since the game board 10 stands up with most load applied to the lower end which does not appear on the surface as a game surface, almost no load is applied to the upper end part which contacts the guide roller 41a ((a) of FIG. 6). reference).

  As described above, the surface of the game board 10 is transported toward the transport surfaces of the member supply path 4a and the member unloading path 4b by configuring the member supply path 4a and the member unloading path 4b using the vertical transport path 4. Even so, there is an effect that the cell attached to the surface of the game board 10 is not damaged.

  In the vertical transport path 4, the dimensions of the upper and left and right ends of the game board 10 to be transported are not limited. Therefore, even if the size of the game board 10 is changed, it is not necessary to change the dimension of the vertical conveyance path 4, and thus there is an effect that it is not necessary to lay again.

  And by using the vertical conveyance path 4 for the member supply path 4a and the member carry-out path 4b, the laying space of the conveyance path is reduced. Therefore, even if the number of router processing machines 2 is increased in order to improve router processing efficiency, there is an effect that the amount of increase in the space for laying the conveyance path can be reduced.

  Further, since the space can be secured between the router processing machine 2 and the member supply path 4a and the member carry-out path 4b, a sufficient space for maintenance can be secured. Therefore, the router processing machine 2, the member supply path 4a and the member carry-out path are secured. The effect that the maintenance of 4b becomes easy is also show | played.

  At the starting point S of the member supply path 4a and the member carry-out path 4b, as shown in FIG. 2, the take-out conveyor C1 is disposed on the conveying surface side of the member supply path 4a and the member carry-out path 4b.

The NIC 96 communicates between the line control device 9 and the NC controller 2i via a data line 96a by communication means corresponding to Ethernet (registered trademark) which is a communication standard of LAN (Local Area Network).

  The communication between the line control device 9 and the NC controller 2i only needs to have a bidirectional communication function, and may be communication according to a serial communication standard such as RS-232C or RS-422, for example.

  In the processing line 1 configured as described above, a process of drilling the game board 10 transported by the transport conveyor C with the router processing machine 2 will be described (see FIGS. 1 to 12 as appropriate).

  The processing line 1 is controlled from the PLC 99 according to a program written in the PLC 99 connected to the line control device 9.

  Further, in the processing line 1, the game board 10 is transported by the transport conveyor C so that the upper end of the game board 10 faces upward in FIG. 2 and the surface of the game board 10 faces the upper surface.

  In the previous step, the game board 10 has cells attached to the surface thereof and is conveyed by the conveyor C in a horizontal state with the surface facing upward. And the game board 10 conveyed to the taking-out conveyor C1 is conveyed to the taking-out position by the taking-out conveyor C1, and stops at the taking-out position.

  A sensor 40b such as a photoelectric sensor as shown in FIG. 6B is also installed at the takeout position of the takeout conveyor C1 to detect that the game board 10 has been transported to the takeout position of the takeout conveyor C1. Thus, it is preferable that the PLC 99 is notified. By configuring as described above, the PLC 99 can detect that the game board 10 has been transported to the take-out position.

  Further, whether the game board 10 is transferred to the upper take-out conveyor C1 or the lower take-out conveyor C1 in FIG. 2 is appropriately selected based on the processing status of the router processing machine 2.

  When the game board 10 stops at the take-out position of the take-out conveyor C1, the PLC 99 moves the base 30 of the riser 3 to the upper part of the game board 10 and rotates the two gripping portions 33, 33 so that the respective gripping grooves 33a and 33a are set in the horizontal direction.

  FIG. 13 is a diagram illustrating a process in which the standing machine stands up the game board. As shown in FIG. 13 (a), the PLC 99 separates the two arm portions 31, 31 so that the interval between the grip portions 33, 33 is wider than the width of the game board 10, and the grip groove 33a, The two gripping arms 32 and 32 are extended by the two vertical movement means 31a and 31a so that 33a becomes the same height as the game board 10, and the gripping portions 33 and 33 are lowered.

  In this state, as shown in FIG. 13 (b), when the PLC 99 moves the two arm portions 31 and 31 in the approaching direction by driving means (not shown), both sides of the game board 10 are placed in the two holding grooves 33a and 33a. The planes are fitted and the game board 10 is gripped by the gripping portions 33 and 33. When the gaming board 10 is gripped, the PLC 99, as shown in FIG. 13C, contracts the two gripping arms 32, 32 upward by the two vertical movement means 31a, 31a, 33 is raised and the game board 10 is lifted from the takeout conveyor C1.

  Next, as shown in FIG. 13 (d), the PLC 99 rotates the gripping part 33 by approximately 90 ° by rotationally driving the rotating means 32 a. Due to this rotation, the gaming board 10 held by the holding portion 33 is in an upright state. At this time, it is preferable to rotate the grip portion 33 in a direction in which the upper end portion of the game board 10 is on the upper side, and it is preferable that the surface of the game board 10 is on the conveying surface side of the member supply path 4a.

  In this state, the PLC 99 horizontally moves the base 30 in the direction of the member supply path 4a and conveys the game board 10 to the upper part of the member supply path 4a, as shown in FIG. Then, as shown in FIG. 13 (f), the PLC 99 uses the two vertical movement means 31a and 31a to extend the two gripping arms 32 and 32 downward to lower the gripping portions 33 and 33, and to play the game board. 10 is placed on the conveying roller 40a of the lower rail 40 of the member supply path 4a.

  When the lower end portion of the game board 10 is placed on the transport roller 40a, the PLC 99 drives a drive means (not shown) as shown in FIG. The two arm portions 31, 31 are separated so as to be larger than the width of the game board 10, and the game board 10 is released from the gripping groove 33a.

  As described above, the game board 10 transported in the horizontal state by the takeout conveyor C <b> 1 stands up and is supplied to the member supply path 4 a including the vertical transport path 4.

  Here, in the lower standing machine 3 in FIG. 2, when the holding portion 33 is rotated so that the upper end of the game board 10 is up when the game board 10 is raised, the surface of the game board 10 is supplied with members. It will be on the opposite side to the conveyance surface of the path 4a. Then, after rotating the holding part 33 and raising the game board 10, the PLC 99 rotates the base 30 by 180 ° in a horizontal plane by a rotating means (not shown) so that the surface of the game board 10 is moved to the member supply path 4 a. Direct toward the transfer surface.

  In addition, it is preferable that the sensor 40b shown by (b) of FIG. 6 is installed also in the supply point where the game board 10 is supplied to the member supply path 4a. The PLC 99 can detect that the game board 10 is supplied to the member supply path 4a by detecting the game board 10 with the sensor 40b at the supply point.

  When the PLC 99 detects that the game board 10 is supplied to the member supply path 4a, the PLC 99 rotates the conveying roller 40a of the member supply path 4a by a driving means (not shown) to bring the game board 10 to the router supply point. Transport. When the game board 10 is detected by the sensor 40b at the router supply point, the PLC 99 stops the rotation of the transport roller 40a and places the game board 10 at the router supply point. In addition, although there are four router supply points in parallel with the member supply path 4a with respect to one router processing machine 2, the game boards 10 are arranged in order from the downstream side of the member supply path 4a.

  In the present embodiment, three router processing machines 2 are installed facing the conveyance surfaces of the pair of member supply paths 4a and the member carry-out paths 4b. Therefore, when there is a waiting router processing machine 2, the PLC 99 places the game board 10 at a router supply point for the waiting router processing machine 2. When all the router machines 2 are processing the game board 10, the PLC 99 does not carry the game board 10 and enters a standby state.

  And if the game board 10 is arrange | positioned at all the four router supply points with respect to one router processing machine 2, PLC99 will make the work hand 8 hung on the upper part of the router processing machine 2 applicable by the drive means 8a. The handhead 80 moves horizontally so that it is above the router supply point.

  FIG. 14 is a diagram illustrating a process in which the work hand supplies the game board to the router processing machine.
