Description

  The present invention relates to a gaming board step-variation apparatus that automatically performs step-breaking of a gaming board.

Conventionally, gaming machines such as pachinko machines equipped with game boards and frames are well known. Such a game board is made by attaching a thin plate member (so-called cell) made of synthetic resin (celluloid, polyester, etc.) having a design property to the surface of a wooden board material (so-called veneer), and placing game nails and objects on the cell. It is configured by arranging. Note that game boards may be stacked (stacked) for the purpose of eliminating restrictions on standby places in the manufacturing process and storage process (see, for example, Patent Document 1).
JP 2002-191776 A (FIG. 2 etc.)

  By the way, it is necessary to separate the stacked game boards one by one when shifting to the next process. However, since the stepping work is performed manually, the burden on the worker is large and the work efficiency is low. In view of this, there has been proposed a step-up device for a game board that can automatically perform step-up of the game board.

  However, in the conventional stage spreader, the stacked veneers are sandwiched one by one from the top and bottom, and are supplied to the downstream conveyor after being stepped, making it difficult to improve work efficiency. is there. If the machine speed of the corrugating apparatus is increased to the limit in order to improve the work efficiency, vibrations and impacts will increase, which may cause some problems in the game board completed through the subsequent steps, The life of the stepping device is also shortened.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a stage-breaking device for a game board that can improve the work efficiency of stage-breaking.

In order to solve the above-mentioned problem, the invention according to claim 1 is a stacking apparatus for stacking game boards in a stacked state, wherein the game board support base supports the game boards in a stacked state. Elevating means for raising or lowering , elevating means detecting means for detecting the game board support that has reached the highest point by being raised by the elevating means, a rod group configured to be able to appear and retract from one end of the cylinder, and A cylinder device having a rod group configured to be able to protrude and retract from the other end of the cylinder, and a pair of clamping members respectively connected to distal ends of the pair of rod groups and capable of coming into contact with and separated from each other. When the holding members approach each other, the game board is held in a holding state from the side, and when the pair of holding members are separated from each other, the holding means that is in an open state not holding the game board is moved up and down. A holding device capable of holding the same number of game boards as the holding means when the holding means of each stage performs a holding operation independently of each other and all the holding means are in the holding state; and the holding device In the apparatus, the game board detection means provided at the same height as the game board held by the holding means of each stage in the apparatus, respectively, are arranged on the downstream side of the game board support base, and a plurality of rollers are spaced at a predetermined interval. And a roller conveyor provided rotatably, and configured to be able to advance and retreat from between the plurality of rollers, and after being advanced from between the plurality of rollers and approaching the clamping device, any of the clamping means of each stage A game board support that supports the game board that is no longer sandwiched by being in the open state and delivers the game board onto the plurality of rollers by lowering and retreating to the lower side of the plurality of rollers Te And a control device that controls the entire device, the control device comprising a central processing unit and a ROM that stores a program used when performing stage separation of the game board, the central processing unit Performs stepping of the game board based on the program stored in the ROM, and the lifting means is positioned above the upper surface of the game board support base by a thickness of one game board. Support board side game board detection means for detecting the presence or absence of the game board, and when all the game board detection means have not detected the game board, the game boards in a stacked state are If the number is equal to or greater than the number of means, the game board support base is raised by the thickness of the same number of game boards as the holding means, and the game board detection means corresponding to the uppermost holding means detects the game board. All the game board detection means When the game board detection signal is output to the central processing unit, all the holding means simultaneously hold the game board and enter the holding state, and all the game board detection means detect the game board. In the case where there are fewer game boards in the stacked state than the holding means, the game board support base is raised to a position where the game board support base is detected by the lifting means detection means, When the gaming board support base has risen from the lowermost holding means to the highest point, which is a position below the thickness of one gaming board, the supporting board side gaming board detection means detects the gaming board. When the game board is no longer used, the game board support base is lowered, and the holding device has the predetermined holding means in the open state, so that the game board is supported by the game board support table and then the open state. The gripper became When the game board detecting means corresponding to the player no longer detects the game board, it waits for the game board support table to rise again by lowering the thickness of one game board, and The gist of this invention is that the game board detecting means corresponding to the holding means moves to the game board support base side when the game board is no longer detected.

  Therefore, according to the first aspect of the present invention, when the game board detecting means corresponding to the uppermost holding means detects the game board, all of the holding means can hold the game board at the same time, thereby allowing stepping. The step spread can be completed in a short time. Furthermore, even when the number of stacked game boards is less than the sandwiching means, if the lifting means detection means detects the game board support base, the game board support base will not rise any further, so the game board support The stand will not move in vain. Therefore, the work efficiency of the step spread is improved. Moreover, since the clamping device has a plurality of stages of clamping members at the top and bottom, it is easy to reduce the operating range of the clamping members. Therefore, it is possible to reduce the size and space of the holding device.

  In addition, even if the holding means for holding the game board is in an open state and no longer holds the game board, the game board is not dropped on the roller conveyor, but is supported by the game board support table to the roller conveyor. It is delivered on a plurality of rollers provided. Therefore, the game board can be prevented from being damaged when the game board is supplied to the roller conveyor.

  Here, the number of game boards in a stacked state is preferably about 20. If there are too many game boards, there is a risk that the game boards in a stacked state will collapse. In addition, when a game board is stacked with game nails and guide rails attached to the game board surface, a large load is applied to the game board near the bottom stage, so the game attached to the game board near the bottom stage Nail and guide rail may be deformed. On the other hand, if the number of game boards is too small, a large number of stacked game board groups are generated, so that a large space is required for waiting these game board groups. The number of game boards in a stacked state is preferably a multiple of the number of the holding means. In this way, the same number of stacked game boards as the holding means can be stepped up to the last one, so even in the last one stage, the board is not used for holding the game board and is wasted. There are no pinching means. Therefore, the work efficiency of the step breaker is further improved.

  The clamping device has a plurality of clamping means. The number of stages of the clamping means is not particularly limited, but for example, it is preferably 3 stages. If the clamping device has four or more clamping means, the structure of the clamping device becomes complicated, making it difficult to manufacture the clamping device. Further, since the holding device becomes heavier as the structure of the holding device becomes complicated, it is necessary to use a high output device as a lifting device for driving the holding device. On the other hand, if the holding device has only two steps of holding means, the holding device can only hold the same number of game boards as the holding means at the time of stepping, so that the work efficiency of stepping will be greatly improved. I can't.

  The game board detection means may be a non-contact detection means for detecting the game board in a non-contact state, or may be a contact-type detection means for detecting the game board in a contact state. Good.

Here, an optical sensor etc. are mentioned as a non-contact-type detection means. The optical sensor includes a light emitting unit provided on one of the pair of clamping members and a light receiving unit provided on the other of the pair of clamping members, and the game board blocks the light from the light emitting unit. An opposing optical sensor that detects the game board when the light receiving part is unable to receive light (Claim 2 ), or a light emitting part in which the light emitting part and the light receiving part are positioned on one of the pair of holding members and reflected from the game board For example, a reflection type optical sensor that detects the game board by receiving light from the light receiving unit may be used. In addition, examples of the non-contact type detection means include a proximity sensor that detects the game board when the game board approaches.

  Examples of the contact detection means include a touch sensor that detects the game board when the game board comes in contact, and a mechanical switch (mechanical switch) that detects the game board when pressed by the game board.

Further , according to the first aspect of the present invention, the elevating means lowers the game board support base when the support base side game board detection means stops detecting the game board, so that the next stacked state is reserved. The game board at can be put on the game board support base immediately. Thereby, since the next step separation can be performed immediately, the work efficiency of the step separation is further improved. Further, the holding means that is in an open state and no longer supports the game board is lowered by the thickness of one game board when the game board support table that supports the game board is lowered. As a result, the holding means on the upper stage side of the holding means in the opened state is positioned immediately above the game board support table that rises again, so that the holding means on the upper stage side becomes one. When in the open state, the game board is supported by the game board support table without falling. Therefore, the game board can be surely transferred from the holding means to the game board support table, so that the game board can be prevented from being damaged due to falling.

  The support base side game board detection means may be the non-contact detection means for detecting in a non-contact state with respect to the game board, or the contact-type detection means for detecting in a contact state with respect to the game board. It may be.

According to a second aspect of the present invention, in the first aspect , the game board detection unit includes a light emitting unit provided on one of the pair of holding members and a light receiving unit provided on the other of the pair of holding members. A light sensor that detects the game board when the light from the light emitting part is blocked by the game board and the light receiving part becomes unable to receive light. The gist of the invention is that it is arranged so as to be orthogonal to the direction in which the light from the light emitting section passes.

Therefore, according to the second aspect of the present invention, since the support base side game board detection means is arranged so as to be orthogonal to the light passing direction from the light emitting portion, the support base side game board detection means and the game board detection Even if the means approach each other, the detection means do not interfere with each other.

As described above in detail, according to the first and second aspects of the present invention, it is possible to provide a step-up device for a gaming board that can improve the work efficiency of step-up. According to the first aspect of the present invention, since the game board can be reliably transferred from the clamping means to the game board support table, the game board can be prevented from being damaged due to falling.

  The carry-in side roller conveyor 22 has a length that allows a plurality of game board groups 11a to be arranged and supported at the same time, and has a total length of several meters to several tens of meters. A plurality of rollers 31 are rotatably disposed on the carry-in side roller conveyor 22 at a predetermined interval. All the rollers 31 are arranged at the same height, and are arranged in a straight line along the conveying direction of the game board group 11a. These rollers 31 are arranged such that the rotation axis is orthogonal to the transport direction of the game board group 11a. Further, the dimension of the roller 31 in the rotation axis direction is set to be slightly larger than the length of each side constituting the outer shape of the game board 11. The interval between the adjacent rollers 31 is shorter than the length of one side of the game board 11 and is set to about 5 to 20 cm. And when the game board group 11a is mounted in the carrying-in side roller conveyor 22, the peripheral surface of each roller 31 comes into contact with the back surface of the lowermost game board 11 constituting the game board group 11a. . In other words, the game board group 11 a can be placed on each roller 31. Each roller 31 rolls when the game board group 11a is transported to promote smooth movement of the game board group 11a.

  As shown in FIG. 2, the stage separation device 10 includes a control device 101 that controls the entire device. The control device 101 includes a CPU 102, a ROM 103, a RAM 104, an input / output circuit, and the like. The CPU 102 controls the stage variation of the game board 11 by the stage separation apparatus 10. Specifically, the CPU 102 has motor drivers for the rotation drive motor of the carry-in roller conveyor 22, the rotation drive motor 43 of the roller conveyor 23 with lift, and the rotation drive motor of the carry-out roller conveyor 24, respectively. They are connected via a circuit (not shown) to control their drive. The CPU 102 controls operations of the elevating means 34, the elevating device 91, the transfer machine 51, and the game board support table 71. The ROM 103 stores a program used when the gaming board 11 is stepped.

  A keyboard 105 and a display 106 are connected to the CPU 102 shown in FIG. The keyboard 105 is for inputting information such as a production plan of the game board 11 to the CPU 102. The display 106 displays the number of game board groups 11a existing on the carry-in side roller conveyor 22 and the carry-out side roller conveyor 24, whether or not the game board group 11a exists on the roller conveyor 23 with a lift, and the like. It is like that. Note that the display 106 may display a mark or the like indicating the occurrence of an abnormality in the step-barashi device 10.

  Further, the stage separation apparatus 10 includes an elevating means detection sensor 111 which is an “elevating means detecting means”. The lifting means detection sensor 111 is disposed in the vicinity of the roller conveyor 23 with lift. The lifting / lowering means detection sensor 111 of the present embodiment is a counter-type optical sensor, and a light-emitting unit (not shown) and a light-receiving unit (not shown) provided on the opposite side of the light-emitting unit across the roller conveyor 23 with a lift. And. The lifting means detection sensor 111 detects the roller conveyor 23 with a lift when the roller conveyor 23 with a lift that has reached the highest point blocks the light from the light emitting section and the light receiving section cannot receive light (becomes an ON state). ) In this case, the lifting means detection sensor 111 outputs a highest point arrival signal to the CPU 102. On the other hand, when the light receiving unit can receive light from the light emitting unit, the lifting means detection sensor 111 does not detect the roller conveyor 23 with a lift that has reached the highest point (becomes an OFF state). In this case, since the lifting means detection sensor 111 does not detect the roller conveyor 23 with a lift, it does not output the highest point arrival signal. The highest point of the present embodiment is a position below the lowermost stage chuck 52 by the thickness of one game board 11.

  As shown in FIG. 2, the stage breaker 10 includes a support base game board detection sensor 112 which is “support base game board detection means”. The support base side game board detection sensor 112 is attached to the roller conveyor 23 with a lift, and is provided at a position above the upper surface of the roller conveyor 23 with a lift by a thickness of one game board 11. The support base side game board detection sensor 112 according to the present embodiment is an opposed optical sensor, and a light emitting unit (not shown) and a light receiving unit (on the opposite side of the light emitting unit across the roller conveyor 23 with a lift). (Not shown). The support board side game board detection sensor 112 is configured such that the game board group 11a (specifically, the lowermost game board 11 constituting the game board group 11a) on the roller conveyor 23 with a lift blocks light from the light emitting unit. When the light receiving unit becomes unable to receive light, the game board 11 is detected (turned on). In this case, the support base side game board detection sensor 112 outputs a game board support signal to the CPU 102. On the other hand, when the light receiving unit can receive light from the light emitting unit, the support base side game board detection sensor 112 does not detect the game board group 11a (becomes an off state). In this case, since the support base side game board detection sensor 112 does not detect the game board group 11a, it does not output a game board support signal. The light passing direction from the light emitting unit constituting the support base game board detection sensor 112 is orthogonal to the light passing direction from the light emitting unit 83 constituting the optical sensor 82.

  Next, a step separation method using the step separation apparatus 10 will be described. In addition, the game board group 11a includes the clamping process S1, the ascending process S2, the first releasing process S3, the first delivering process S4, the second releasing process S5, the second delivering process S6, the third releasing process S7, and the third delivering process. The steps are separated in the order of S8 → return step S9.

  In the previous step of the sandwiching step S1, the plywood (game board 11) to which the cells are attached is stored in a stock conveyor for a predetermined time in a stacked state, and the cells are fixed to the plywood. After a certain period of time, the stacked game boards 11 (game board group 11a) are placed on the carry-in side roller conveyor 22. Here, since each roller 31 included in the carry-in side roller conveyor 22 is always driven to rotate by an actuator such as a rotation drive motor, the game board group 11a placed on the carry-in side roller conveyor 22 remains as it is on the carry-in side. It moves to the downstream side of the roller conveyor 22.

  Next, the CPU 102 rotates and rotates the rotation drive motor 43 included in the roller conveyor 23 with a lift via the motor driver circuit. As a result, the game board group 11a moves onto the roller conveyor 23 with a lift. And CPU102 performs control which stops the rotational drive motor 43 via a motor driver circuit. Thereby, each roller 42 stops and the game board group 11a on the roller conveyor 23 with a lift stops. At this point, the CPU 102 performs control to drive the stopper device 33 at the downstream end of the carry-in roller conveyor 22 and moves (protrudes) the stopper pin upward. As a result, the outer peripheral surface of the stopper pin comes into contact with the game board group 11a that has subsequently moved on the carry-in side roller conveyor 22, and the game board group 11a becomes immovable.

  In the sandwiching step S1, the CPU 102 performs control for driving the elevating means 34 to raise the roller conveyor 23 with lift. CPU102 of this embodiment is when the game board 11 on the roller conveyor 23 with a lift is the same number or more as the chuck | zipper 52 (namely, when the game board 11 which comprises the game board group 11a is 3 or more). In addition, control is performed to raise the roller conveyor 23 with a lift by the thickness of three game boards 11. At this point, since there are 18 game boards 11 constituting the game board group 11a, the CPU 102 performs control to raise the roller conveyor 23 with a lift by the thickness of three game boards 11. . On the other hand, when there are fewer game boards 11 on the roller conveyor 23 with a lift than the chucks 52 (that is, when there are two or less game boards 11 constituting the game board group 11a), the CPU 102 detects the lifting means. Control is performed to raise the roller conveyor 23 with a lift to a position where the sensor 111 detects the roller conveyor 23 with a lift. That is, the CPU 102 performs control to raise the roller conveyor 23 with a lift until the highest point arrival signal is output from the lifting means detection sensor 111.

  Thereafter, the CPU 102 waits until all the optical sensors 82 can detect the game board 11 (that is, until the game board detection signals are output from all the optical sensors 82). Control to drive the rodless cylinder 93 is performed to lower the transfer machine 51 (see FIG. 7A). When the optical sensor 82 corresponding to the uppermost chuck 52 detects the game board 11 (that is, when the gaming board detection signal is output from the optical sensor 82 corresponding to the uppermost chuck 52), the CPU 102 Then, control for driving all the cylinder devices 54 is performed. As a result, each chuck 52 sandwiches the game board 11 at the same time and enters a sandwiched state (see FIG. 7B). In addition, the detection method of the game board 11 by the optical sensor 82 is as follows. That is, when the game board 11 is not present, the light receiving unit 84 of the optical sensor 82 receives the light from the light emitting unit 83 without being blocked by the game board 11, so the optical sensor 82 does not detect the game board 11. No game board detection signal is output (in an off state). On the other hand, when the game board 11 is present, the game board 11 blocks light from the light emitting unit 83. At this time, since the light receiving unit 84 of the optical sensor 82 cannot receive the light from the light emitting unit 83, the optical sensor 82 detects the game board 11 and outputs a game board detection signal (turns on).

  In the subsequent ascending step S2, the CPU 102 performs control to drive the second rodless cylinder 93 of the elevating device 91 and raises the transfer machine 51 to the ascending end (see FIGS. 8A and 8B). In the subsequent first opening step S3, the CPU 102 performs control to drive the first rodless cylinder 92 of the lifting device 91, and moves the transfer machine 51 that has reached the rising end to above the game board support table 71. Then, the control to drive the second rodless cylinder 93 is performed, and the transfer machine 51 is lowered to the supply point (see FIG. 9A). Then, the CPU 102 performs control to drive the lowermost cylinder device 54 to open the lowermost clamping member 53 (see FIG. 9B). As a result, the game board 11 held by the lowermost holding member 53 is supported by the support member 72 of the game board support table 71.

  In the subsequent first delivery step S4, the CPU 102 performs control to drive the cylinder 73 and lowers the support member 72. When the arm portion 72 a of the support member 72 is retracted to the lower side of the plurality of rollers 61 constituting the carry-out side roller conveyor 24, the game board 11 supported by the support member 72 is transferred onto each roller 61. (See FIGS. 10A and 10B). In addition, since each roller 61 of this embodiment is always rotationally driven by actuators, such as a rotational drive motor, the game board 11 delivered on each roller 61 is directly downstream of the carrying-out side roller conveyor 24. Moving. Further, the CPU 102 detects that the optical sensor 82 corresponding to the lowermost chuck 52 that has been released no longer detects the gaming board 11 (that is, the gaming board detection signal from the optical sensor 82 corresponding to the lowermost chuck 52). Is controlled to drive the second rodless cylinder 93. Thereby, the transfer machine 51 descends by the thickness of one game board 11 and waits until the support member 72 rises again.

  In the subsequent second opening step S5, when the game board 11 delivered onto each roller 61 moves downstream, the CPU 102 performs control to drive the cylinder 73 again to raise the support member 72 and The part 72a is advanced from between the rollers 61 to approach the transfer machine 51 (see FIG. 11A). When the support member 72 rises, the CPU 102 performs control to drive the middle cylinder device 54 to open the middle clamping member 53 (see FIG. 11B). As a result, the game board 11 held by the intermediate holding member 53 is supported by the support member 72 of the game board support table 71.

  In the subsequent second delivery step S <b> 6, the CPU 102 performs control to drive the cylinder 73 and lowers the support member 72. When the arm portion 72 a of the support member 72 is retracted to the lower side of each roller 61 constituting the carry-out side roller conveyor 24, the game board 11 supported by the support member 72 is transferred onto each roller 61. (See FIGS. 12A and 12B). In addition, the game board 11 delivered on each roller 61 moves to the downstream side of the carry-out side roller conveyor 24 as it is. Further, the CPU 102 outputs a game board detection signal from the optical sensor 82 corresponding to the middle stage chuck 52 when the optical sensor 82 corresponding to the middle stage chuck 52 that has been released no longer detects the game board 11. When the operation is stopped, the second rodless cylinder 93 is controlled to be driven. Thereby, the transfer machine 51 descends by the thickness of one game board 11 and waits until the support member 72 rises again.

  In the subsequent third opening step S7, when the game board 11 delivered onto each roller 61 moves downstream, the CPU 102 performs control to drive the cylinder 73 again to raise the support member 72 and The part 72a is advanced from between the rollers 61 to approach the transfer machine 51 (see FIG. 13A). When the support member 72 rises, the CPU 102 performs control to drive the uppermost cylinder device 54 and opens the uppermost clamping member 53 (see FIG. 13B). As a result, the game board 11 held by the uppermost holding member 53 is supported by the support member 72 of the game board support table 71.

  In the subsequent third delivery step S8, the CPU 102 performs control to drive the cylinder 73, and lowers the support member 72. When the arm portion 72 a of the support member 72 is retracted to the lower side of each roller 61 constituting the carry-out side roller conveyor 24, the game board 11 supported by the support member 72 is transferred onto each roller 61. (See FIGS. 14A and 14B). In addition, the game board 11 delivered on each roller 61 moves to the downstream side of the carry-out side roller conveyor 24 as it is.

  In the subsequent return step S9, when the game board 11 delivered on each roller 61 moves downstream, the CPU 102 performs control to drive the cylinder 73 again to raise the support member 72 and to move the arm portion 72a. Is advanced from between the rollers 61 (see FIGS. 15A and 15B). Further, the CPU 102 stops outputting the game board detection signal from the optical sensor 82 corresponding to the uppermost chuck 52 when the optical sensor 82 corresponding to the uppermost chuck 52 no longer detects the game board 11. ) To move the transfer machine 51 to the roller conveyor 23 with lift. Specifically, the CPU 102 controls the drive of the second rodless cylinder 93 of the lifting device 91 at the same time that the support member 72 starts to rise, and raises the transfer machine 51 to the rising end (FIG. 15 ( b)). Further, the CPU 102 performs control to drive the first rodless cylinder 92 of the lifting device 91 and moves the transfer machine 51 that has reached the rising end to above the roller conveyor 23 with a lift (see FIG. 15A). . At this time, since there are 15 game boards 11 constituting the game board group 11a, the CPU 102 performs control to drive the lifting means 34, and the lift-equipped roller conveyor 23 is provided for three game boards 11. And then wait until the transfer machine 51 arrives.

  Thereafter, by repeating the sandwiching step S1 to the return step S9, the stage variation of the game board group 11a on the roller conveyor 23 with the lift is continued. Then, the CPU 102 determines whether or not the roller conveyor 23 with lift has reached the highest point based on whether or not the highest point arrival signal is output from the lifting / lowering means detection sensor 111. When the highest point arrival signal is output from the lifting means detection sensor 111, that is, when the roller conveyor 23 with lift reaches the highest point, the CPU 102 outputs a game board support signal from the support base side game board detection sensor 112. It is determined whether or not it has been done. When the game board support signal is not output from the support board side game board detection sensor 112, that is, when the game board group 11a does not exist on the roller conveyor 23 with a lift, the CPU 102 performs control to drive the lifting means 34. Thus, the roller conveyor 23 with a lift is lowered until it becomes the same height as the carry-in side roller conveyor 22. Further, the CPU 102 ends the control for driving the stopper device 33 and moves the stopper pin downward. Thereby, the game board group 11a on the carry-in side roller conveyor 22 becomes movable. Then, the CPU 102 controls to rotate the rotation drive motor 43 of the roller conveyor 23 with lift, and rotates each roller 42. As a result, the next game board group 11a moves onto the roller conveyor 23 with a lift. Thereafter, the above-described sandwiching step S1 to return step S9 are repeated.

  Therefore, according to the present embodiment, the following effects can be obtained.

  (1) In the stage separation apparatus 10 of the present embodiment, when the optical sensor 82 corresponding to the uppermost stage chuck 52 detects the game board 11, all the chucks 52 hold the game board 11 at the same time, thereby providing stage separation. Is done. Therefore, since the three game boards 11 can be pinched and separated by one operation, the step dispersion can be completed in a short time. Further, even if the number of game boards 11 constituting the game board group 11a is smaller than that of the chuck 52, if the lifting means detection sensor 111 detects the roller conveyor 23 with a lift, the roller conveyor 23 with a lift further rises. Therefore, the roller conveyor 23 with lift does not move wastefully. Therefore, the work efficiency of the step spread is improved. Moreover, since the work efficiency is not improved by increasing the speed of the transfer machine 51, problems such as vibration, shock, machine life, and safety are unlikely to occur. Moreover, since the transfer machine 51 has a plurality of stages of holding members 53 at each stage, it is easy to reduce the operating range of the holding members 53. Therefore, the transfer machine 51 can be reduced in size and saved in space.

  (2) The lift-equipped roller conveyor 23 of the present embodiment is configured to rise by the thickness of three game boards 11 in the return step S9 (see FIGS. 15A and 15B). For this reason, the distance that the transfer machine 51 descends in the next clamping process S1 is the same as the distance that the transfer machine 51 descends in the previous clamping process S1. Therefore, even if the stepping work of the game boards 11 progresses and the number of the game boards 11 constituting the game board group 11a decreases, the distance that the transfer machine 51 descends is always equal. Therefore, the stage separation can be completed in a short time regardless of the progress state of the stage separation work, so that the work efficiency of the stage separation is further improved. Further, since the moving distance of the transfer machine 51 in the clamping process S1 to the return process S9 is always equal, it is not necessary to provide a plurality of types of programs for driving the transfer machine 51.

  (3) In the present embodiment, the game board 11 sandwiched between the chucks 52 is directly placed on the respective rollers 61 of the carry-out side roller conveyor 24, and then the chuck 52 is opened to place the game board 11 in the respective rollers 61. It can be considered to be handed over. However, since the pair of contact portions 53b sandwich the side surface 11b of the game board 11, there is a high possibility that the clamping member 53 interferes with the roller 61 when the game board 11 is placed. Even if the game board 11 can be placed, the holding members 53 interfere with the rollers 61 when the pair of holding members 53 are separated from each other to be in the open state. I can't hand it over.

  Therefore, in the present embodiment, when the chuck 52 that holds the game board 11 is in an open state and no longer holds the game board 11, the game board 11 is first supported by the game board support table 71 and then each roller 61. Passed over. Therefore, since the game board 11 can be successfully transferred onto each roller 61, it is difficult for the game board 11 and the holding member 53 to be impacted, and damage to the game board 11 and the holding member 53 can be prevented.

  (4) The clamping member 53 of the present embodiment is not in contact with only one place on the side surface 11b of the game board 11, but is in contact with two places (within the area A1 shown in FIG. 1). . Thereby, the contact area of the clamping member 53 and the game board 11 becomes large. Moreover, since the contact portion 53b is made of metal, the contact portion 53b is not deformed when contacting the side surface 11b of the game board 11. Therefore, the game board 11 can be firmly held by the pair of holding members 53, and the game board 11 can be transported stably.

  In addition, the pair of clamping members 53 is not in the corner portion of the game board 11 but so as to vertically contact two parallel sides of the four sides constituting the outer shape of the game board 11 so as to sandwich the game board 11. It has become. For this reason, the game board 11 can be stably clamped regardless of the size of the game board 11. For example, a general game board (so-called standard board) having a substantially square shape of 471.5 mm in length and 446.5 mm in width is a large game board having a substantially square shape of 500 mm in length and 482 mm in width (so-called large size). Even if it is a board), the game board 11 can be held by the pair of holding members 53.

  In addition, you may change this embodiment as follows.

  The “game board detection means” in the above embodiment is an opposed optical sensor 82 that detects the game board 11 when the game board 11 blocks the light from the light emitting section 83 and the light receiving section 84 cannot receive light. It was. However, the light emitting unit 83 and the light receiving unit 84 are positioned on one of the pair of holding members 53, and the game board 11 is detected when the light receiving unit 84 receives light from the light emitting unit 83 reflected by the game board 11. A reflective optical sensor, a proximity sensor that detects the game board 11 when the game board 11 approaches, or the like may be used as the “game board detection means”. Also, a “game board detection means” may be composed of a camera that takes an image and a CPU 102 (central processing unit) that determines the presence or absence of the game board 11 by analyzing the image taken by the camera. The “game board detection means” is not limited to the non-contact type detection means (optical sensor, proximity sensor, camera), and is detected in contact with the roller conveyor 23 with lift and the game board 11. Contact type detection means (such as a mechanical switch) may be used.

  -The raising / lowering means detection sensor 111 and the support stand side game board detection sensor 112 of the said embodiment are opposing type optical sensors, and were provided with the light emission part (not shown) and the light-receiving part (not shown). However, the lifting / lowering means detection sensor 111 and the support base side game board detection sensor 112 may be a reflection type optical sensor or a proximity sensor, or may be composed of the camera and the CPU 102 as described above. Further, the lifting means detection sensor 111 and the support base side game board detection sensor 112 are not limited to the above-mentioned non-contact type detection means (light sensor, proximity sensor, camera), and the roller conveyor 23 with lift and the game board are not limited. 11 may be contact-type detection means (such as a mechanical switch) that detects the contact state in a contact state.

  -The raising / lowering means 34 of the said embodiment was provided with the guide rail extended along an up-down direction, and moved the roller conveyor 23 with a lift attached to the guide rail up and down with actuators, such as an air cylinder. However, the elevating means 34 is not limited to the configuration of the above-described embodiment. For example, a lift attached to the ball screw by including a ball screw extending in the vertical direction and driving the motor to rotate the ball screw. The attached roller conveyor 23 may be moved up and down.

  -Although the contact part 53b of the said embodiment was set so that a contact area with the game board 11 might become large as it became the clamping member 53 of the lower stage side, each contact part 53b is the game board 11 and the contact area. You may set so that all contact areas may become the same.

  In the above embodiment, the optical sensor 82 corresponding to the chuck 52 at each stage is provided in the lowermost clamping member 53. However, the optical sensor 82 may be provided in the clamping member 53 at each stage.

  -Although the roller conveyor 23 with a lift of the said embodiment was raised in return process S9 (refer FIG. 15 (a), (b)), ascending process S2 (refer FIG. 8 (a), (b)) and As long as it is between the return step S9, it may rise at any step.

  The game board 11 of the above embodiment is stacked in a state in which the component attachment holes 13 and 14 are formed and the game nails 17, the guide rails 18a and 18b, the corner decorative members 19 and 20, and the like are attached. . However, the game boards 11 may be stacked in any state. For example, the game boards 11 may be stacked in a state before the game nails 17 are driven, or the game boards 11 may be stacked in a state before the component mounting holes 13 and 14 are formed.
