Description

The present invention relates to a game board manufacturing system used for producing the gaming machine game board of typified pachinko machine.

  Conventionally, gaming machines such as pachinko machines equipped with game boards and frames are well known. Such game boards and frames are individually manufactured on a game board production line and a frame production line, respectively, and these are organically and integrally assembled to complete a pachinko machine. In the production line for game boards, a device for cell pasting process (see, for example, Patent Document 1) for pasting cells on plywood for game boards is arranged. Specifically, the production line 50 was coated with a hot press device 51 for raising the surface temperature of the plywood (about 70 to 80 ° C.), an adhesive application device 52 for applying an adhesive to the surface of the plywood, and an adhesive. A cell sticking device 53 for sticking the cells to the plywood and a cold press device 54 for pressing the plywood on which the cells are stuck at room temperature are arranged in this order (see FIG. 11). The cold press device 54 is for increasing the degree of adhesion by removing bubbles remaining between the cell and the plywood during pressurization. Further, a multi-axis drilling machine 55 for making a reference hole, a rail pin hole, and the like is disposed on the downstream side of the cold press device 54 in the production line 50.

  If the multi-axis drilling machine 55 is arranged adjacent to the cold press device 54, it is possible to make holes in the plywood immediately after the cells are attached to the plywood, so that the production efficiency of the production line 50 can be increased. it can. However, immediately after applying the cell, the adhesive is not yet dried, and the cell is not completely adhered to the plywood. Therefore, if drilling is performed in this state, the cells may be peeled off or torn, and defective products may occur frequently. Moreover, sawdust (wood waste) may enter between the cell and the plywood from the holed portion, and the surface of the cell may swell.

In order to solve these problems, a cold press device 54 and a multi-spindle drilling machine 55 are equipped with a facility for storing the plywood on which the cells are adhered until the adhesive is completely dried, a drying facility for rapidly drying the adhesive, and the like. It is necessary to provide between. In general, although various drying facilities for rapid drying have been proposed, it is mainly used for drying after bonding papers, cloths, and plywood, and drying after bonding plywood and cells There is no track record used for. In addition, the adhesive agent used for cell sticking usually adheres in a short time by increasing the temperature and promoting the drying of moisture. However, since such an adhesive also has high fluidity when the temperature is high, the cell immediately after application is easy to slide on the surface of the plywood. Therefore, in order to completely bond (fix), it is necessary to lower the fluidity of the adhesive by lowering the temperature conversely during drying. Therefore, even if the plywood and the cell are bonded using the above-described drying equipment, it is not known whether the adhesive can be dried well. In addition, since the drying equipment is large, it is necessary to consider the initial investment amount and running cost. Therefore, at present, a stock conveyor 56 that is cheaper than the drying equipment is provided in the production line 50, and the plywood with the cells attached is stored in the stock conveyor 56 for a certain period of time (about 1 hour) to completely bond the cells and the plywood. And then drilling holes.
JP 2003-180976 A

  However, since the stock conveyor 56 stores the plywood with cells attached in a stacked state, the stack transfer device for stacking and the stacking transfer for performing stacking after storage. A device is required. As a result, the production line 50 is enlarged and the installation space is increased. Moreover, the method of storing the plywood with the cells attached thereto on the stock conveyor 56 for a certain period of time is low in productivity of the game board because it takes time to fix the cells. Furthermore, if stacking is performed with dust or wood chips remaining attached to the front surface of the cell or the back surface of the plywood, the cell may be damaged or dented.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a game board manufacturing system capable of preventing the decorative sheet from being damaged, reducing the installation space, and improving productivity. It is to provide .

In order to solve the above problems, the invention according to claim 1 is a heating device that raises a surface temperature of the wooden board for game board by heating the wooden board for game board, and is heated by the heating device. An adhesive application device that applies an adhesive to the surface of the game board wooden board, and a resin decorative sheet is applied to the surface of the game board wooden board to which the adhesive has been applied by the adhesive application device. A decorative sheet sticking device, a cold press device that pressurizes in the thickness direction while sandwiching a wooden board for game board on which the decorative sheet is stuck by the decorative sheet sticking device, and a game board on which the decorative sheet is stuck A game board manufacturing system comprising a drilling device for drilling a wooden board for a game, wherein the cold press device is a wooden board for a game board to which the decorative sheet is attached. And a pressing member that can be moved up and down above the substrate supporting table, and the pressing member is capable of circulating a coolant near the bottom surface of the inner layer portion. together with the cooling liquid channel is formed, between the bottom surface and the cooling fluid flow path is formed using a high thermal conductivity material relative to the substrate support the bottom surface in a state toward the substrate supporter a pressing member main body toward and away Te, the bottom surface and the mechanical strength than the material forming between the coolant flow path is formed by a not high high thermal conductivity materials Rutotomoni, the pressing member main body Is attached to the lower part of the board so that it can move up and down, and is in surface contact with the wooden board for game board supported on the upper surface of the board support base and presses the wooden board for game board, and the press approaching the board support base Bottom of member body Also includes a pressing member in surface contact, the cold pressing apparatus, as the lowering of the pressing member, the decorative sheet being attached to the game board for wooden substrate supported by the substrate support table top The pressing member is brought into surface contact with each other, and after performing the substrate pressing step for pressing the decorative sheet, as the pressing member is further lowered, the pressing member main body is brought into surface contact with the pressing member, The gist of the game board manufacturing system is characterized in that a pressing step of pressing the decorative sheet is performed by both the pressing member main body and the pressing member .

  Therefore, according to the first aspect of the invention, between the bottom surface of the pressing member main body and the coolant flow path, the pressing member is formed of a high thermal conductivity material, and the coolant flow path is formed near the bottom surface of the inner layer portion. Therefore, the cold press apparatus has a cooling function. As a result, when the wooden board for game board to which the decorative sheet is affixed is sandwiched and pressed by the cold press device, the heat of the wooden board for game board, the decorative sheet and the adhesive is transmitted to the pressing member body via the pressing member. And is carried away by the coolant flowing through the coolant flow path in the pressing member body. Along with this, the adhesive is cooled and the fluidity is lost. As a result, the decorative sheet and the game board wooden board are completely bonded to each other. Therefore, even if a hole is made in the game board wooden board to which the decorative sheet is attached, the decorative sheet may be peeled off or torn. It becomes difficult.

  In addition, since the fluidity of the adhesive can be reliably lost with a cold press device, equipment for storing the wooden board for game boards with a decorative sheet attached thereto until the adhesive has dried, or drying to dry the adhesive Equipment is not required. As a result, the game board manufacturing system is reduced in size, so that the installation space can be reduced. Moreover, even if the game board wooden board with the decorative sheet is not stored for a certain period of time, the cold press device loses the fluidity of the adhesive so that the decorative sheet can be used in a very short time. Since it can be fixed on the board, the productivity of the game board is improved.

Further, when the pressing member main body when moved in a direction away from the substrate support, cooling means for cooling by sending air to the gap formed between the pressing member main body and the pressing member is provided, the pressing Both the member main body and the pressing member can be efficiently cooled. Moreover, since the pressing member is formed of a high thermal conductive material having a mechanical strength higher than that of the pressing member body, it is possible to prevent the pressing member from being deformed when the game board wooden board is pressed.

  Here, the “high thermal conductivity material” that forms the pressing member between the bottom surface and the coolant channel refers to a material having a thermal conductivity of 50 W / m · K or more, specifically, , Copper (370 W / m · K), aluminum (236 W / m · K), iron (83.5 W / m · K), and the like. The “thermal conductivity” described here conforms to the heat flow meter method defined in JIS A1412.

Further, the pressing member is made of a highly heat conductive material having a higher mechanical strength and a proof stress of 150 N / mm ² or more than the material forming the space between the bottom surface and the coolant flow path. Examples of the high thermal conductivity material forming the pressing member include aluminum and iron when the material forming the space between the bottom surface and the coolant flow path is copper. Here, “mechanical strength” is defined as “bending strength” defined by JIS R1601, “tensile strength” defined by JIS Z2241, and defined by JIS Z2241. It refers to “proof strength” etc.

  In addition, the pressing member main body may be made of, for example, a rectangular parallelepiped block material or a plate material formed in a box shape. Here, it is preferable that the pressing member main body has a structure that can be divided into a plurality of (for example, two) members. In this way, the coolant channel can be easily formed in the inner layer portion of the pressing member body. Specifically, if the structure of the pressing member main body cannot be divided, it is necessary to make a hole in the pressing member main body in order to form the coolant channel. In this case, it is difficult to make the coolant flow path into a complicated shape. On the other hand, if the pressing member main body has a structure that can be divided, it is possible to easily form a complex coolant flow path by simply forming a groove on at least one of the dividing surfaces of each member.

  Further, examples of the air cooling means include those that send the surrounding air as it is with a blower, and those that cool the surrounding air with a cooling means (for example, a heat pump) and send the cold air with a blower. In the case where the air-cooling means sends the surrounding air as it is with a blower, the air-cooling means can be formed at a low cost. On the other hand, in the case where the air cooling means is one that sends cold air with a blower, the cooling efficiency by the air cooling means is improved.

The coolant flow path may be divided into a plurality of systems along the surface direction of the bottom surface.

When the coolant flow path is not divided, the coolant flowing through the start end of the coolant flow path is cold, but as the coolant approaches the end of the coolant flow path, the coolant becomes the wooden board for the game board, the decorative sheet, and the adhesive. Cooling efficiency is poor because it gets warm from heat. On the other hand, lever to divide the coolant flow passage into a plurality systems, the distance of the respective cooling fluid channel is shortened, even the coolant does not easily become warm in the vicinity of the end of each cooling fluid channel. Therefore, the cooling efficiency is improved.

According to a second aspect of the present invention, in the first aspect of the present invention, air cooling means is provided on the side of the pressing member to send air to cool the gap generated between the pressing member main body and the pressing member, and the gap Is opened in a direction orthogonal to the conveying direction of the wooden board for game board, and the cold press device, in the pressing step, transfers heat of the wooden board for game board to the pressing member and the pressing member. is absorbed into the cooling liquid flowing through the cooling fluid flow path through the body, after the pressing step, performed spacing step for separating the bottom side of the pressing member main body from the pressing member, after the separation step, said pressing member as its gist to carry out the cooling step of cooling send air prior SL gap from the side.

Therefore, according to the second aspect of the present invention, in the pressing step, the bottom surface of the pressing member main body is brought into surface contact with the pressing member, and the wooden board for game board on which the decorative sheet is attached is used as both the pressing member main body and the pressing member. When the pressure is pressed, the heat of the wooden board for game board, the decorative sheet, and the adhesive is transmitted to the pressing member main body through the pressing member, and is carried away by the cooling liquid flowing through the cooling liquid passage in the pressing member main body. Along with this, the adhesive is cooled and the fluidity is lost. As a result, in the punching process after the pressing process, even if the drilling is performed on the wooden board for game board to which the decorative sheet is attached, the decorative sheet is hardly peeled off or torn.

Furthermore, since the cooling step is performed after the separation step and air is sent to the gap formed between the pressing member main body and the pressing member for cooling, both the pressing member main body and the pressing member can be quickly cooled. As a result, the heat of the wooden board for a game board that has been transported next can be immediately transferred to the coolant, thereby improving the manufacturing efficiency of the game board.
The invention according to claim 3 is the invention according to claim 1 or 2, wherein the pressing member main body includes an upper member constituting an upper part of the pressing member main body and a lower member constituting a lower part of the pressing member main body. The gist of the invention is that the cooling liquid flow path is formed in a divided portion of the upper member and the lower member, which can be divided from each other below the middle.

As described in detail above, according to the inventions described in claims 1 to 3 , a game board manufacturing system that can prevent the decorative sheet from being damaged, can reduce the installation space, and can improve productivity. Can be provided .

In addition, the cold press apparatus 17 pressurizes in the state cooled to 1-5 degreeC lower than the temperature (around 10 degreeC) of an adhesive agent. As a result, the plywood 22, the cell 23, and the adhesive are cooled, the bubbles remaining between the cell 23 and the plywood 22 are removed, and the degree of adhesion is increased. Further, the multi-axis drilling machines 18 and 19 which are “drilling devices” are arranged adjacent to the cold press device 17 on the downstream side of the cold press device 17. The multi-axis drilling machines 18 and 19 are configured to perform a drilling process for drilling a reference hole, a rail pin hole, the component mounting holes 24 and 25 and the like on the plywood 22 to which the cell 23 is attached. Since a plurality of multi-axis drilling machines 18 and 19 are provided in order to improve the working efficiency of drilling, either one of the multi-axis drilling machines 18 and 19 may be omitted.
(3) Configuration of the cold press device 17

  As shown in FIGS. 3 to 7, the cold press device 17 includes a substrate support base 31 and a pressing member 32. The substrate support 31 is configured to support the plywood 22 with the cells 23 affixed to the upper surface 31a thereof.

  The pressing member 32 is provided above the substrate support 31 and moves up and down as the piston rod 41 and guide rod 30 connected to the pressing member 32 move up and down. The piston rod 41 is driven by an actuator (not shown). The guide rod 30 is provided on both sides of the piston rod 41 and is driven by the piston rod 41. Each guide rod 30 is for preventing the pressing member 32 from inclining when moving up and down. In addition, the actuator of this embodiment consists of a hydraulic cylinder, an air cylinder, and a servomotor. The hydraulic cylinder is disposed on the same axis as the piston rod 41, and is for driving the piston rod 41 by hydraulic pressure. The hydraulic cylinder generates a driving force stronger than that of the air cylinder and the servo motor. The air cylinder is offset from the piston rod 41 and the hydraulic cylinder, and is used to finely adjust the moving amount of the piston rod 41 by air pressure. The servo motor is for finely adjusting the movement amount of the piston rod 41, and performs finer adjustment than fine adjustment by the air cylinder. The servo motor is configured to drive the piston rod 41 via a pinion gear attached to the rotation shaft of the servo motor and a rack gear provided on the side surface of the piston rod 41 and meshing with the pinion gear. Note that the servo motor may be configured to drive the piston rod 41 via a ball screw.

As shown in FIGS. 3 to 7, the pressing member 32 includes a pressing member main body 33 and a pressing member 34. The pressing member main body 33 approaches and separates from the substrate support base 31 with the lower member 36 facing the substrate support base 31. The pressing member main body 33 is formed of a block material having a substantially rectangular parallelepiped shape with a length of 480 mm, a width of 580 mm, and a height of 365 mm. As shown in FIG. 7, the pressing member main body 33 includes an upper member 35 that constitutes the upper part of the pressing member main body 33 and a lower member 36 that constitutes the lower part of the pressing member main body 33. 36 has a structure that can be divided from each other. A gasket (not shown) is interposed between the upper member 35 and the lower member 36. The gasket of the present embodiment is a liquid gasket applied to at least one of the dividing surface 35a of the upper member 35 and the dividing surface 36a of the lower member 36, but is preferably a plate-like gasket. The upper member 35 is formed of a block material having a substantially rectangular parallelepiped shape with a length of 480 mm, a width of 580 mm, and a height of 350 mm, and the lower member 36 is a block having a substantially rectangular parallelepiped shape with a length of 480 mm × width of 580 mm × height of 15 mm. It is made of material. A plate 37 having a length of 480 mm, a width of 580 mm, and a thickness of 2 mm is attached to the entire bottom surface of the lower member 36 (that is, a part between the bottom surface of the pressing member main body 33 and the coolant flow path 38). Yes. Note that the upper member 35, the lower member 36, and the plate 37 of the present embodiment are made of a highly thermally conductive material, specifically, copper having a thermal conductivity of 370 W / m · K. Further, the copper forming the upper member 35, the lower member 36, and the plate 37 has a yield strength of about 140 N / mm ² . However, the upper member 35 and the lower member 36 may be formed of aluminum.

  As shown in FIG. 6 and FIG. 7, the coolant that can circulate in the vicinity of the bottom surface of the inner layer portion of the pressing member main body 33 (the divided portion of the upper member 35 and the lower member 36 in this embodiment). A flow path 38 is formed. The coolant flow path 38 is a tubular flow path bent at a plurality of locations (see FIG. 6), and is formed in the groove 35 b formed in the split surface 35 a of the upper member 35 and in the split surface 36 a of the lower member 36. The groove 36b is formed. Therefore, the grooves 35b and 36b have the same shape. The distance between the bottom surface of the groove 36b and the lower surface of the plate 37 (the surface that contacts the pressing member 34) is preferably 5 mm or more and 7 mm or less (7 mm in this embodiment). If the distance is less than 5 mm, the lower member 36 becomes too thin, and the rigidity of the lower member 36 is reduced. On the other hand, when the distance is larger than 7 mm, the cooling liquid flow path 38 and the plywood 22 supported by the substrate support base 31 are too separated from each other, so that the plywood 22, the cell 23, and the adhesive can be efficiently cooled. Disappear. Further, an inflow portion 39 having an inflow port is provided at the start end of the coolant flow path 38, and a discharge portion 40 having a discharge port is provided at the end of the coolant flow path 38. In addition, the inflow part 39 and the discharge | emission part 40 of this embodiment are 20 mm in internal diameter, and are general purpose goods used for water supply. Therefore, the inner diameter of the coolant channel 38 is also 20 mm, which is the same as the inner diameter of the inflow portion 39 and the discharge portion 40. Then, the cooling liquid discharged from the discharge unit 40 is sent to the water cooling means (not shown) via the discharge path (not shown) and cooled again, and cooled via the inflow path (not shown) and the inflow part 39. It flows into the liquid flow path 38. The water-cooling means of this embodiment includes a radiator (cooler) to which a coolant is supplied and a blower that cools the coolant in the radiator by applying air to the radiator. The discharge path is preferably meandering. In this way, the cooling liquid is cooled even when flowing through the discharge path, so that the cooling efficiency of the cooling liquid is further improved.

As shown in FIGS. 3 to 7, the pressing member 34 is formed of a highly thermally conductive material having higher mechanical strength than the material (copper) forming the upper member 35, the lower member 36, and the plate 37. Has been. The pressing member 34 of this embodiment is formed of aluminum (JIS A5052) having a thermal conductivity of 236 W / m · K and a proof stress of 215 N / mm ² . The pressing member 34 is formed in a U shape by bending an aluminum plate (thickness 2 to 3 mm), and includes a member main body 42 and a pair of arm portions 43. The member main body 42 has a substantially rectangular plate shape of 500 mm long × 600 mm wide, and each arm portion 43 has a substantially rectangular plate shape of 200 mm long × 500 mm wide. Since the specific gravity of aluminum is 2.7, the weight of the member main body 42 is about 2.0 kg, and the weight of one arm portion 43 is about 0.68 kg. Therefore, the weight of the entire pressing member 34 is about 3.4 kg.

  As shown in FIG. 4, long holes 44 extending in the vertical direction (the height direction of the arm portion 43) are formed at both ends of each arm portion 43. Each long hole 44 is inserted with a pin 45, and the tip of each pin 45 is inserted and fixed in the pressing member main body 33. Accordingly, the pressing member 34 is attached to the lower portion of the pressing member main body 33 so as to be movable up and down.

The pressing member 34 comes into surface contact with the plywood 22 supported on the upper surface 31a of the substrate support 31 and presses the plywood 22 by its own weight (see FIG. 9B). Thereby, the position shift to the horizontal direction of the cell 23 stuck on the plywood 22 is prevented. The force for pressing the plywood 22 is about 3.4 kg, which is the same as the weight of the pressing member 34. Further, the pressing member 34 comes into surface contact with the plate 37 of the pressing member main body 33 which is close to the substrate support base 31 (see FIG. 9C).
(4) Configuration of air cooling means

  An air cooling means (not shown) is provided on the side of the pressing member 32. The air cooling means is configured to send air to a gap formed between the pressing member main body 33 and the pressing member 34 when the pressing member main body 33 moves in a direction away from the substrate support base 31 (arrow in FIG. 4). F1 direction reference). In addition, said clearance gap is opened in the direction orthogonal to the conveyance direction (refer arrow F2 direction of FIG. 3) of the plywood 22. FIG. As a result, the pressing member main body 33 and the pressing member 34 are cooled. In addition, the air cooling means of this embodiment consists of an air blower, and sends surrounding air with an air blower as it is.

  As shown in FIG. 8, the game board 21 is manufactured in the order of the substrate heating process S1, the adhesive application process S2, the cell application process S3 (decorative sheet application process), the press process S4, and the punching process S5. . More specifically, in the substrate heating step S <b> 1, the surface temperature of the plywood 22 is increased by heating the plywood 22 conveyed via the plywood conveying conveyor 11 and the transfer machine 13 with the hot press device 14. In the adhesive application step S <b> 2, an adhesive is applied to the surface of the plywood 22 heated by the hot press device 14. In the cell sticking step S3, the cell 23 is stuck on the surface of the plywood 22 to which the adhesive is applied.

  In the pressing step S4, the cold press device 17 is used to press in the thickness direction while sandwiching the plywood 22 with the cells 23 attached thereto. In the pressing step S4, the work is performed in the order of the substrate placement step S4-1 → the substrate pressing step S4-2 → the pressing step S4-3 → the separation step S4-4 → the cooling step S4-5. More specifically, in the substrate placement step S4-1, the plywood 22 to which the cells 23 are attached is placed horizontally on the upper surface 31a of the substrate support 31 (see FIG. 9A). In the substrate pressing step S4-2, as the piston rod 41 of the air cylinder is driven to lower the pressing member 32, the pressing member 34 is brought into surface contact with the plywood 22 supported by the upper surface 31a to press the plywood 22 ( (See FIG. 9B). In the pressing step S4-3, as the piston rod 41 is driven to further lower the pressing member 32, the bottom surface (plate 37) of the pressing member main body 33 is brought into surface contact with the pressing member 34 to press the plywood 22. It presses with both the member main body 33 and the pressing member 34 (refer FIG.9 (c)). Thereby, the heat of the plywood 22, the cell 23, and the adhesive is transmitted to the lower member 36 through the pressing member 34 and the plate 37, and absorbed by the coolant flowing through the coolant flow path 38. As a result, the surface temperature of the cell 23 is lowered, the adhesive is cooled and the fluidity is lost, and the cell 23 is fixed to the plywood 22. In the subsequent separation step S4-4, as the piston rod 41 is driven to raise the pressing member 32, the bottom surface (plate 37) of the pressing member body 33 is separated from the pressing member 34, and the pressing member 34 is further moved to the plywood 22. Separate from. At this point, the plywood 22 supported on the upper surface 31a is transported to the multi-axis drilling machine 18, 19 side. Thereafter, in the cooling step S4-5, air is sent by a blower to cool the gap formed between the pressing member main body 33 and the pressing member 34 in the separation step S4-4. This cooling step S4-5 is performed until the next plywood 22 is conveyed to the cold press device 17.

  In the drilling process S5 after the pressing process S4, the multi-axis drilling machines 18 and 19 perform drilling to open the reference holes, rail pin holes, component mounting holes 24 and 25, and the like on the plywood 22 to which the cells 23 are attached. Thereafter, the game board 21 is completed by performing processes such as gauge press, NC nailing, automatic rail fastening, NC windmill driving, corner decoration, accessory insertion, automatic screw fastening, wiring, display board attachment, and the like.

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

  (1) The temperature of the conventional cold press device 54 (see FIG. 11) is about 0 ° C. in winter and about 30 ° C. in summer in the initial state. However, the temperature of the cold press device 54 rises to about 60 ° C. while repeating the pressing process in which the plywood with the cells attached is sandwiched and pressed by the cold press device 54, and it cannot be called “cold press”. It becomes. Especially in summer, the temperature rises quickly. In this case, the heat of the plywood, the cell, and the adhesive is not absorbed by the cold press device 54 when performing the pressing process. As a result, since the adhesive remains in a state where the fluidity remains high, the cell and the plywood cannot be completely bonded.

  On the other hand, in the game board manufacturing system 10 of the present embodiment, the plate 37 of the pressing member main body 33 constituting the cold press device 17 is formed of copper, which is a high thermal conductivity material, and the pressing member 34 also constituting the cold press device 17. Is made of aluminum which is a high thermal conductivity material. Further, a coolant flow path 38 is formed in the vicinity of the bottom surface of the inner layer portion of the pressing member main body 33. Therefore, the cold press apparatus 17 comes to have a cooling function. Thereby, when performing a press process, the heat | fever of the plywood 22, the cell 23, and an adhesive agent is transmitted to the press member main body 33 via the press member 34, and the cooling which distribute | circulates the cooling fluid flow path 38 in the press member main body 33 is distribute | circulated. Taken away by liquid. Along with this, the adhesive is cooled and the fluidity is lost. As a result, since the cell 23 and the plywood 22 are completely bonded, even if the plywood 22 to which the cell 23 is attached is punched, the cell 23 is hardly peeled off or torn.

  Further, since the fluidity of the adhesive can be reliably lost by the cold press device 17, a facility for storing the plywood 22 to which the cells 23 are attached until the adhesive is dried (for example, the stock conveyor shown in FIG. 11). 56) and a drying facility for drying the adhesive are not required. As a result, the game board manufacturing system 10 is reduced in size, so that the installation space can be reduced. Further, since it is not necessary to perform maintenance on the stock conveyor 56, the amount of work during maintenance can be reduced. Moreover, even if the plywood 22 to which the cells 23 are attached is not stored for a certain period of time, the cell 23 can be fixed to the plywood 22 in a very short time by causing the cold press device 17 to lose the fluidity of the adhesive. Therefore, the productivity of the game board 21 is improved.

  (2) In the present embodiment, when the pressing member main body 33 moves in a direction away from the substrate support base 31, a blower that sends air to the gap generated between the pressing member main body 33 and the pressing member 34 and cools it ( Since air cooling means) is provided, both the pressing member main body 33 and the pressing member 34 can be efficiently cooled. Moreover, since the gap is opened in a direction perpendicular to the conveyance direction of the plywood 22 (see arrow F2 in FIG. 3), the air from the blower does not interfere with the conveyance of the conveyance machine. Sent to. Therefore, both the pressing member main body 33 and the pressing member 34 can be cooled more efficiently. Further, since the pressing member 34 is formed of a high thermal conductive material (aluminum) having a mechanical strength higher than that of the pressing member main body 33, the pressing member 34 can be prevented from being deformed when the plywood 22 is pressed.

  (3) In the present embodiment, the height of the upper member 35 of the pressing member main body 33 is 350 mm, and the height of the lower member 36 of the pressing member main body 33 is 15 mm. For this reason, the pressing member main body 33 is not a structure that is divided in the middle, but a structure that is divided below the middle. That is, since the coolant channel 38 is as close as possible to the plywood 22 supported by the substrate support 31, the plywood 22, the cell 23, and the adhesive can be cooled more efficiently.

  In addition, you may change this embodiment as follows.

  As shown in FIG. 10, the coolant flow path 38 of the above embodiment is divided into a plurality of systems (four systems in FIG. 10) along the surface direction of the bottom surface of the pressing member body 33, and a plurality of coolant flow The paths 46, 47, 48, and 49 may be used. In this way, the distance between the coolant channels 46 to 49 is shorter than the coolant channel 38 of the above embodiment, so that the coolant is warm even near the end of each coolant channel 46 to 49. Hard to become. Therefore, the cooling efficiency is improved.

  Next, in addition to the technical ideas described in the claims, the technical ideas grasped by the embodiment described above are listed below.
