Abstract

<P>PROBLEM TO BE SOLVED: To allow the direction of a game board to meet a direction suitable for a work machine in a supply destination or a supply source. <P>SOLUTION: When it is required that the direction of the game board 4 to be supplied to or discharged from the work machine is inverted, in a state where an inverting part 7 is positioned to be lower than a carrier part 6, the carrier part 6 stops a carrier operation, while mounting the game board 4. The inverting part 7 is elevated, so as to mechanically lift up the game board 4 from the carrier part 6, support it, and invert the direction of the game board 4 by e.g., 180° on a plane. The inverting part 7 is lowered, so as to lift down the game board 4 onto the carrier part 6 for mounting. Then the carrier part 6 restarts the carrier operation, and carries out the direction-inverted game board 4 onto conveyors 2, 3 for supplying the game board 4 to the work machine or onto a conveyor for carrying the game board 4 from the work machine to a succeeding process. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine manufacturing redirection device for automatically adjusting the direction of a game board supplied to a processing machine or a game board discharged from the processing machine to a direction suitable for a processing machine of a supply destination or a supply source.

A nail driving apparatus for manufacturing a game machine disclosed in Japanese Patent Application Laid-Open No. 6-114147 has a configuration in which a carry-in / carry-out conveyor is arranged in two rows between two sets of rows in which a plurality of nailers are arranged in tandem. The game board is transported to the position of each nailing machine in each set row by the conveyor, and after the game machine is positioned and mounted on the mounting table of the nailing machine from the carry-in conveyor, the nailing machine corresponds to the nailing data corresponding to the game board. The nails such as game nails are driven one by one according to the position and the order of. When the driving of the predetermined number of game nails is completed, the game board is taken out from the mounting table and transferred to the carry-out conveyor, and the carry-out conveyor conveys the game board to the next step, the accessory mounting step. However, in the conventional nailing device, in order to facilitate the maintenance and inspection of the nailing machine in each group, each nailing machine in one group is arranged in tandem in the same direction, and the other group is used. Are arranged in tandem in the same direction so as to be opposite to the direction of the nailing machine in one group. For this reason, the direction of the game board related to the nailing machine of one set row is opposite to the direction of the game board related to the nailing machine of the other set row. For this reason, the carry-in conveyor, the carry-out conveyor, and the upper and lower transport mechanisms are arranged in two rows, the interval between the plurality of rows of nailing machines is widened, and a plurality of nailing machines are used in view of the building. In some cases, it could not be installed in a group. In addition, game boards delivered from the router processing process, which is the previous process, are stacked in multiple stages for the same model to form blocks, and these blocks are individually placed on a hand-held cart and transported to the upstream side of each loading conveyor In the process of turning, the bogie is turned so that the direction of the block is adapted to the direction of the nailing machine for each group of rows. Therefore, the number of loading conveyors must be the same as the number of rows of nailing machines, and a large space for turning the bogie is required. Also, when carrying out the nailing-completed game board to a later-stage accessory mounting process, the orientation of the game board related to the nailing machine in one group and the nailing machine in the other group are also considered. Since the direction of the game board related to (1) is opposite to that of the game board, the direction of the nailed game board has been artificially changed before the game board is carried out to the assembling process which is a subsequent process. Therefore, a discriminating device for detecting the direction of the component supplied to the reversing table, a reversing table for guiding the component in one direction, and a feed claw are provided, and the component is moved from the upstream side to the reversing table by the feed claw. The discrimination device detects the direction of the component conveyed by the feed claw, and if the discrimination device determines that the orientation of the component is reversed, after rotating the reversing table on which the component is mounted by 180 ° horizontally. Although it is conceivable to transport the components downstream from the reversing table using the feed claw, the feed claw and the reversing table have a structure independent of each other, so that the rotation angle range of the reversing table is 90 ° or 270 °. If the angle is set to a value other than 180 °, the mechanism of the feed claw becomes complicated because the feed claw needs to be configured to rotate in accordance with the rotation angle of the reversing table.
JP-A-6-114147 Japanese Utility Model Publication No. 56-121533

  The problem to be solved by the invention is that when the rotation angle range of the reversing table is set to other than 180 °, such as 90 ° or 270 °, the mechanism of the feed claw becomes complicated.

  The redirection device for manufacturing a gaming machine according to the present invention is provided with a transport unit capable of transporting / stopping the transport by mounting a game board to be supplied to the processing machine or a game board discharged from the processing machine, and a higher and lower level than the transport unit. The most main feature of the present invention is that it has a reversing section which can be moved up and down and can be rotated and stopped horizontally in a predetermined rotation angle range after stopping and moving up to a higher position.

  In the reversing device for manufacturing a gaming machine according to the present invention, it is necessary to reverse the direction of the game board supplied to the processing machine or the game board discharged from the processing machine in a state in which the reversing section is located below the transport section. If there is, the transport unit mounts a game board loaded from the previous process of the processing machine or a game board unloaded from the processing machine and interrupts the transport operation, the reversing unit rises and the game unit is moved from the transport unit to the machine. After reversing the direction of the game board by, for example, 180 ° in a plane, the reversing section descends and the game board is settled on the transport section, and then the transport section resumes the transport operation. Then, the game board whose direction is reversed is carried out from the conveyor for supplying the processing machine or the conveyor to the next process from the processing machine. In the state where the reversing unit is positioned lower than the transporting unit, when it is not necessary to reverse the direction of the game board to be supplied to the processing machine or the game board discharged from the processing machine, the transporting unit is more than the previous process of the processing machine. The direction of the game board can be changed by transporting the game board to the processing machine or the conveyor for the next process from the processing machine to the conveyor for the next process in a direction in which the loaded game board or the game board unloaded from the processing machine is mounted. There is an advantage that it can be automatically aligned in a direction suitable for the processing machine of the supply destination or supply source. When the transport unit is set to a position other than 180 °, for example, 90 ° or 270 °, the transport unit is rotated by 90 ° or 270 ° in a state where the reversing unit is positioned lower than the transport unit. , The mechanism for unloading the game board from the transfer unit is simplified. Therefore, there is an advantage that the carry-out direction of the game board can be easily switched to an angle other than 180 °.

Are arranged in tandem to facilitate maintenance and inspection of the nailing machine 1. For example, each nail driving machine 1 in one set row A located on the right side of the carry-in conveyor 2 is arranged in a row with the table 1a oriented in the same direction as the transport direction X, and the game board 4 is placed on the table 1a. The out-opening 4a, the notch 4b, and the like are mounted so as to face the upstream side in the transport direction X to perform nailing. The nailing machines 1 in the other row B located on the left side of the carry-in conveyor 2 are arranged in cascade with the table 1a facing in the opposite direction to the transport direction X, and the table 1a has an out port 4a of the game board 4 and The notch 4b or the like is mounted so as to face the downstream side in the transport direction X and nailing is performed. For this reason, when the carry-in conveyor 2 conveys the game board 4 toward each nailing machine 1 in the right side of the assembly row A, the carry-in conveyor 2 moves the out-opening 4a, the notch 4b, and the like of the game board 4 in the conveyance direction X. When the game board 4 is conveyed toward each of the nailing machines 1 in the row B on the left side of the game board 4, the out-opening 4 a and the notch 4 b of the game board 4 are moved downstream in the conveyance direction X. To the side. For this purpose, the carry-in side switching mechanism 5 is arranged upstream of the carry-in conveyor 2.

  The carry-in side reversing mechanism 5 includes a transport unit 6, a reversing unit 7, and a supply destination determination processing unit 8. The supply destination determination processing unit 8 is controlled by a control device 1 b (see FIG. 2) having a computer for each nailing machine 1. It is determined whether the nailing machine 1 which has issued the material request command belongs to the group A or the group B according to the material request command. Is determined to be required, the destination determination processing unit 8 outputs a posture switching operation command to the transport unit 6 and the reversing unit 7, and the game board 4 loaded from the previous process is transported higher than the reversing unit 7. When properly mounted on the section 6, the transport section 6 interrupts the transport operation, the reversing section 7 ascends and the gaming section 4 is mechanically levitated and supported by the transport section 6 so that the orientation of the gaming panel 4 is 180 °. After reversing in the plane, the reversing unit 7 descends and the game board 4 is settled and mounted on the transport unit 6 and transported. 6 resumes the transport operation and unloads the game board 4 whose direction has been reversed to the carry-in conveyor 2, and conversely, it is necessary to reverse the direction of the game board 4 to be supplied to the nailing machine 1 in the row B Is determined, the supply destination determination processing unit 8 outputs a posture switching non-operation command to the transport unit 6 and the reversing unit 7, and the transport unit 6 higher than the reversing unit 7 keeps the gaming board 4 passed from the previous process as it is. To the carry-in conveyor 2 in the direction of.

  The transport unit 6 is a reversing unit 7 that horizontally rotates a roller conveyor 6c including a conveyor frame 6a having a rectangular shape in a plan view smaller than the game board 4 and a plurality of rollers 6b rotatably supported by the frame, every 180 °. A support member (not shown) is provided on the upstream side of the carry-in conveyor 2 so as not to interfere with the installation.

  The reversing unit 7 is provided with the rotating plate 7 a on the basis of the installation so as to be coaxial below the center of the transport unit 6. A ring gear 7b provided on the rotating plate 7a meshes with a gear 7d coupled to an output end of a motor 7c as a rotary actuator mounted on an installation basis. An air cylinder 7e is mounted on the rotating plate 7a as an elevating actuator. The motor 7c rotates and stops the movable frame 7f having a rectangular shape in plan view disposed outside the conveyor frame 6a horizontally every 180 °. The air cylinder 7e moves up and down the movable frame 7f. The upper end surface 7f-1 of the movable frame 7f for supporting the game board 4 is higher than the upper transport section of the roller conveyor 6c at the upper limit position, and lower than the upper transport section of the roller conveyor 6c at the lower limit position. Become. The movable frame 7f is prevented from swinging by a guide mechanism (not shown), and abutment plates 7g for preventing the game board 4 from jumping out project from the upper end face 7f-1 at the four corners.

  The carry-out conveyor 3 can set the carrying direction to the same direction or the opposite direction to the carrying direction X of the carry-in conveyor 2 depending on the positional relationship between the nailing area and the next process area. In, the transport direction of the unloading conveyor 3 is set to the same direction as the transport direction X of the loading conveyor 2. Therefore, when the unloading conveyor 3 conveys the nailed game board 4 carried out from each nailing machine 1 of the row A on the right side to the next process, the out port 4a of the game board 4 is used. And the notch 4b are conveyed in the opposite direction to the conveying direction X, and the nailed game board 4 carried out from each nailing machine 1 in the left side of the row B is transferred to the next step. When the game board 4 is conveyed, the game machine 4 is conveyed with the out-opening 4a and the notch 4b of the game board 4 in the same direction as the conveyance direction X. For this purpose, the carry-out side switching mechanism 12 is arranged downstream of the carry-out conveyor 3.

  The unloading-side redirecting mechanism 12 includes a transport unit 13, a reversing unit 14, and a supply source determination processing unit 15, and the supply source determination processing unit 15 discharges material from the control device 1b of each nailing machine 1 (see FIG. 2). In accordance with the command, it is determined whether the nailing machine 1 which has issued the material discharging instruction belongs to the group A or the group B, and, for example, the direction of the game board 4 discharged from the nailing machine 1 in the group A Is determined to be reversed, the supply source determination processing unit 15 outputs a posture switching operation command to the transport unit 13 and the reversing unit 14, and the game board 4 is properly transmitted from the unloading conveyor 3 to the transport unit 13 higher than the reversing unit 14. When transported, the transport unit 13 interrupts the transport operation, the reversing unit 14 rises, and the gaming board 4 is mechanically levitated and supported by the transport unit 13 so that the orientation of the gaming board 4 is within a 180 ° plane. After the reversal, the reversing unit 14 descends and the game board 4 sinks on the transport unit 13. The transporting unit 13 resumes the transporting operation, and carries out the game board 4 whose direction has been reversed to the next process, and conversely, the game board 4 discharged from the nailing machine 1 in the group B It is determined that there is no need to reverse the direction, the supply source determination processing unit 15 outputs a posture switching non-operation command to the transport unit 13 and the reversing unit 14, and the transport unit 13 higher than the reversing unit 14 is delivered from the unloading conveyor 3. The game board 4 is carried out to the next process in the same direction.

  The transport unit 13 is a support member (not shown) provided on the downstream side of the unloading conveyor 3 and is provided on an installation basis, and includes a conveyor frame 13a and a roller 13b that do not interfere with the reversing unit 14 like the transport unit 6. 13c. The reversing unit 14 includes a rotating plate 14a, a ring gear 14b, a motor 14c, a gear 14d, an air cylinder 14e, a movable frame 14f, and a contact plate 14g, similarly to the reversing unit 7, and the motor 14c rotates the movable frame 14f by 180 °. Each time, it is horizontally rotated and stopped, and the movable frame 14f is moved up and down by the air cylinder 14e. The upper end surface 14f-1 of the movable frame 14f is higher than the upper transport section of the roller conveyor 13c at the upper limit position, and lower than the upper transport section of the roller conveyor 13c at the lower limit position.

  As shown also in FIG. 2, the carry-in conveyor 2 transports the game board 4 in the transport direction X with the design board surface of the game board 4 facing upward, and the game board 4 is provided with predetermined nails in each of the rows A and B. When reaching the position corresponding to the hitting machine 1, the game board 4 is moved to the predetermined nail driving machine by the stopper 2 a which protrudes from the lower part on the conveyance path of the game board 4 corresponding to the predetermined nail driving machine 1. Stop at the position corresponding to 1. Then, after the carry-in conveyor 2 interrupts the transport operation, the stopper 2a is retracted below the transport path. The game board 4 stopped by the stopper 2a is positioned and mounted on the table 1a of the nailing machine 1 with the design board surface of the game board 4 facing upward by a carry-in loading mechanism (not shown). After the game board 4 is held by the loading loading mechanism, the stopper 2a detects a game board sensor (not shown) that detects that the game board 4 is mounted, or is operated by an operator instead of the game board sensor. Any of the manual switches (not shown) that are turned on outputs a game board type signal and a nailing start signal to the control device 1b of the nailing machine 1. Then, the computer of the control device 1b extracts the nailing positions and order from the nailing data corresponding to the game board type stored in advance in the storage device of the control device 1b, and stores the nailing positions and order. Then, the table 1a is moved vertically and horizontally in the plane, and the predetermined position of the game board 4 on the table 1a is positioned and stopped below the nail holder mechanism 1c and the hammer mechanism 1d installed thereabove. Then, a nail (not shown) called a game nail or an obstacle nail supplied from the nail supply unit 1e such as a parts feeder to the nail holder mechanism 1c is driven into the game board 4 by the hammer mechanism 1d, thereby forming one sheet. A large number of nails to be hit on the game board 4 are automatically driven on the game board 4 one by one. When the driving of the predetermined number of nails is completed, an unloading loading mechanism (not shown) takes out the game board 4 from the table 1a and transfers it to the unloading conveyor 3, and the unloading conveyor 3 transfers the gaming board 4 to the next step, a non-illustrated guide rail. , Center goods, decorations, windmills, winning openings, etc., and transport them to the assembly process for attaching game function parts.

  In addition, the supply destination determination unit 9 of the supply destination determination processing unit 8 determines whether the nailing machine 1 that has output the material requirement command according to the material requirement command from each nailing machine 1 Alternatively, a signal that determines whether the signal belongs to the group B on the left side is output to the redirection determination unit 10 of the supply destination determination processing unit 8. In addition, the attitude detection unit 11 of the supply destination determination processing unit 8 determines whether or not, for example, the out port 4a or the notch 4b of the game board 4 mounted on the transport unit 6 faces upstream in the transport direction X. , The direction of the game board 4 is detected and output to the direction change determination unit 10. Thereby, the direction change determination unit 10 collates the attribute of the set A, B of the nailing machine 1 which has issued the material request command from the supply destination determination unit 9 with the direction of the game board 4 from the position detection unit 11. Then, a posture switching operation command or a posture switching non-operation command is output to the transport unit 6 and the reversing unit 7.

  The attitude detection unit 11 may be either a non-contact type or a contact type. In the case of the non-contact type, for example, an out port is used to specify the orientation of the game board 4 transferred to the transport unit 6 from the previous process. A detection light from a detection light source such as a laser element or an LED element (not shown) is applied to a portion (detection position) where a feature for specifying the direction of the game board 4 such as the notch 4a or the notch 4b may exist. Then, the reflected light from the irradiation field is captured by a detection light source (not shown) that two-dimensionally senses the reflected light, and whether or not the irradiation field has the out port 4a or the notch 4b is detected based on the captured result. The detection is performed in the conclusion part, and the detection result is output to the changeover determination unit 10. In this non-contact type, the detection conclusion unit of the posture detection unit 11, the supply destination determination unit 9, and the turnover determination unit 10 can be configured by a computer. In the case of the contact type, a contact (not shown) can be moved toward a detection position corresponding to the irradiation field, and if the detection position has an out port 4a, a notch 4b, or the like, the contact changes the OFF signal. The contactor outputs an ON signal to the direction change determination unit 10 when the outport 4a or the notch 4b is not present at the detection position. In this contact type, the supply destination determining unit 9 and the redirection determining unit 10 can be configured by a computer.

  Here, since the loading side redirection mechanism 5 and the unloading side redirection mechanism 12 have basically the same mechanism configuration and operation, they will be described in detail with reference to FIG. In FIG. 3, the conveyor frame 20a is a member corresponding to the conveyor frames 6a and 13a, the roller 20b is a member corresponding to the rollers 6b and 13b, and the roller conveyor 20c is a member corresponding to the roller conveyors 6c and 13c. The air cylinder 21e is a member corresponding to the air cylinders 7e and 14e, the movable frame 21f is a member corresponding to the movable frames 7f and 14f, and the upper end surface 21f-1 is the upper end surface 7f-1 and 14f-1. As a corresponding portion, the contact plate 21g is a member corresponding to the contact plates 7g and 14g. First, as shown in Fig. A, the movable frame 21f is stopped at the lower limit position, and the roller conveyor 20c normally mounts the game board 4 and interrupts the transport operation. Thereafter, as shown in Fig. B, the movable frame 21f rises to support the gaming board 4 by floating above the roller conveyor 20c, and then stops at the ascent limit position. Subsequently, as shown in Fig. C, the direction of the game board 4 is switched by the movable frame 21f rotating 180 degrees horizontally and stopping at the ascending limit position. That is, FIGS. 7A and 7B show a state in which the game board 4 has the out port 4a, the notch 4b, and the like positioned on the back side of the drawing, and the movable frame 21f has stopped rotating by 180 °. 4A and 4B show a state in which the notch 4b and the like are located on the front side of the paper. Next, as shown in Fig. D, after the movable frame 21f is lowered and the game board 4 whose direction is switched is mounted on the roller conveyor 20c, the movable frame 21f is lowered to a lower limit position where the movable frame 21f sinks from the upper conveying portion of the roller conveyor 20c. Stop. Then, the roller conveyor 20c restarts the transport operation. The transfer operation of the roller conveyor 20c is set to the same speed as the transfer speed of the carry-in conveyor 2 in the case of the carry-in side reversing mechanism 5, and to the same speed as the transfer speed of the carry-out conveyor 3 in the case of the carry-out side reversing mechanism 12. Then, the delivery or acceptance of the game board 4 can be performed smoothly.

  For example, in order to directly transfer the game board 4 conveyed by a conveyor (not shown) from the router processing step to the roller conveyor 6c of the carry-in side change mechanism 5, the game board 4 arrives at the carry-in side change mechanism 5. Before carrying out, the roller conveyor 6c is driven to rotate in the transport direction X by a motor (not shown) at the same speed as the transport speed of the conveyor in the router processing step, and a stopper (not shown) is provided on the downstream side in the transport direction X. After projecting above the upper conveyor of the roller conveyor 6c along the movable frame 7f, after stopping the movement of the game board 4 transferred to the roller conveyor 6c from the conveyor on the router processing step side by a stopper not shown in the figure. Then, the rotation drive of the roller conveyor 6c is stopped. Alternatively, in order to supply the game board 4 transported from the router processing step to the carry-in side switching mechanism 5 by a hand mechanism such as a manipulator or a robot (not shown), the roller conveyor 6c is stopped.

  In order to directly transfer the game board 4 conveyed by the unloading conveyor 3 to the roller conveyor 13c of the unloading side reversing mechanism 12, the roller board 13c must be moved before the game board 4 arrives at the unloading side reversing mechanism 12. Is rotated by a motor (not shown) in the transport direction X at the same speed as the transport speed of the unloading conveyor 3, and a stopper (not shown) is provided on the roller conveyor 13c along the movable frame 14f on the downstream side in the transport direction X. After projecting above the upper conveying section and stopping the movement of the game board 4 transferred from the unloading conveyor 3 to the roller conveyor 13c by a stopper (not shown), the rotation drive of the roller conveyor 13c is stopped.

  According to this embodiment, the carry-in side reversing mechanism 5 provided on the upstream side of the carry-in conveyor 2 automatically adjusts the direction of the game board 4 so as to match the direction of the nailing machine 1 to which the game board 4 is supplied. And then carried out to the carry-in conveyor 2. The loading board 2 conveys the game board 4 to the nailing machine 1 arranged on the side. Then, the game board 4 is positioned and mounted on the table 1a of the nail driving machine 1 from the carry-in conveyor 2, and the nail driving machine 1 automatically drives the nails into the game board 4 one by one. Then, when the nailing is completed, the game board 4 is discharged to the carry-out conveyor 3 arranged on the side of the nailing machine 1. Then, the direction of the nailing-completed game board 4 is automatically aligned according to the direction of the nailing machine 1 from which the game board 4 has been ejected by the unloading side reversing mechanism 12 provided on the downstream side of the unloading conveyor 3. After that, it is carried out to the next process side. Therefore, it is possible to improve the economy and productivity of nailing work when manufacturing a gaming machine.

  In addition, when the orientation of the game board 4 in the carry-in side reversing mechanism 5 and the direction of the nailing machine 1 to which the game board 4 is supplied match, the posture switching operation of the carry-in side reversing mechanism 5 is not performed. In addition, the game board 4 can be supplied to the nailing machine 1 of the supply destination via the carry-in conveyor 2 from the carry-in side reversing mechanism 5. If the orientation of the game board 4 in the loading-side switching mechanism 5 does not match the orientation of the nailing machine 1 to which the gaming board 4 is supplied, the attitude switching operation of the loading-side switching mechanism 5 is performed. By doing so, after switching the direction of the game board 4 to the same direction or the opposite direction to the transport direction X, the game board 4 can be supplied from the loading side reversing mechanism 5 to the nailing machine 1 of the supply destination via the loading conveyor 2. .

  In addition, when the orientation of the game board 4 in the unloading-side redirecting mechanism 12 matches the orientation of the nailing machine 1 as the supply source of the gaming board 4, the attitude switching operation of the unloading-side redirecting mechanism 12 is performed. Instead, the game board 4 can be conveyed to the next process side from the unloading side redirection mechanism 12. If the orientation of the game board 4 at the unloading-side redirecting mechanism 12 does not match the orientation of the nailing machine 1 as the supply source of the gaming board 4, the attitude switching operation of the unloading-side redirecting mechanism 12 is performed. After switching the direction of the game board 4 to the same direction as the transport direction X or the opposite direction, the game board 4 can be supplied from the unloading side change mechanism 12 to the next process side.

  In addition, a transport mechanism in which a row of carry-in conveyors 2 and a row of carry-out conveyors 3 are vertically arranged between a group A of nailing machines 1 and a group B of nailing machines 1 is arranged. Therefore, the interval between the group A and the group B can be reduced, and the installation density of the nailing machine 1 can be increased.

  Further, since the number of the carry-in conveyor 2 and the carry-out conveyor 3 is reduced to the minimum number such as one row, the apparatus can be simplified.

  As shown in FIG. 3A or FIG. 3D, when the gaming board 4 is levitated and supported by the roller conveyor 20c in the carry-in / carry-out side change mechanisms 5, 12, the conveyor is stopped while the transport operation of the roller 20b is stopped. After the rotation of the frame 20a is stopped within a predetermined rotation angle range by a rotary actuator such as a motor (not shown), the transport operation of the rollers 20b is resumed, and the unloading direction of the game board 4 is changed to the loading and unloading conveyors 2, 3. The direction can be switched to a direction intersecting the transport direction X at, for example, 90 ° or 270 ° or another angle.

  In the above-described embodiment, the rotation angle range of the movable frames 7f and 14f is set to 180 °, and the orientation of the game board 4 corresponding to the nailing machine 1 in the group A as one group is reversed. It is also possible to reverse the direction of the game board 4 corresponding to each of the nailers 1 in the rows A and B by setting one or a plurality of angles. For example, in the unloading-side redirection mechanism 12, the rotation angle range of the movable frame 14f is set to 180 °, which rotates in two directions, left and right, at every 90 °, and the game board 4 from the nailing machine 1 in the row A is set. If the game board 4 is controlled to rotate 90 ° to the left on the paper of FIG. 2 and to the game board 4 from the nail driving machine 1 in the group B, it is rotated 90 ° to the right on the paper of FIG. The game board 4 can be oriented so that the out opening 4a and the notch 4b of the game board 4 face the left side in FIG. The rotation angle range can be applied to angles other than 90 °, 180 °, and 270 °.
