Description

  The present invention prevents the decorative sheet from being peeled off from the game board and the cutting tool when the cutting tool of the router machine cuts the through hole from the game board side to the decorative sheet side to form the game board. The present invention relates to a base plate for drilling a game board capable of improving the durability of the game board.

As disclosed in Patent Document 1, a game board of a pachinko machine is integrally joined to the front surface of a game board in which a decorative sheet having a design drawing drawn on the back surface is formed in a substantially square shape by wood such as veneer. In addition, a through hole for attaching a game function component is formed. Further, the back surface of the game board has a dent used for positioning a game function component attached to the back surface of the game board. By the way, when forming a through hole and a recess in the game board, if the through hole is drilled from the front side of the game board, that is, the decorative sheet side, and the recess is drilled from the back side of the game board, that is, the game board side, Drilling is a two-step process, which is economically disadvantageous. For this reason, as shown in FIG. 5, when the through hole 20 and the recess 21 are drilled in one step from the back side of the game board 22, the drill 23 is used when the through hole 20 is formed. The cut edge of the decorative sheet 24 may be peeled off from the game board 25 and turned up. When this turning up occurs, cutting waste 26 such as sawdust enters between the turned up decorative sheet 24 and the game board 25, and the periphery of the through hole 20 of the decorative sheet 24 is on the front side of the game board 22. It will remain swelled. In the case where game function parts such as tulips (not shown), center bonuses, winning holes, and attackers are attached to the front of the game board 22 while the decorative sheet 24 is raised, the height of the game function parts is unreasonably high. In addition, game function parts may be distorted. Thus, if the gaming functional parts are unreasonably high, there is a disadvantage that the glass is damaged when the gaming board 22 is assembled to the machine frame attached to the island of the pachinko store and the glass of the machine frame is closed. In addition, when the game functional part has a movable part, the movable part may malfunction due to the distortion. Therefore, the cutting that has entered between the decorative sheet 24 and the game board 25 after drilling is performed. The waste 26 is removed manually, and there is a limit to reducing the cost. In order to eliminate such inconvenience, as shown in FIG. 6, a wooden floor board 27 such as veneer is superposed on the decorative sheet 24 of the game board 22 and the punching process is performed from the back side of the game board 22. However, the floor board 27 is likely to warp due to moisture absorption, which is one of the characteristics of natural wood, and when this warpage occurs, a gap 28 is provided between the mating surfaces of the decorative sheet 24 and the floor board 27. In the gap 28, the same inconvenience as described above occurs, which is difficult to adopt.

  The problem to be solved by the invention is that when the cutting tool of the router machine cuts the through hole from the game board side to the decorative sheet side to form the game board, the decorative sheet peels off from the game board. It is that the durability of the cutting tool cannot be improved.

  The base plate for drilling processing of a game board according to the present invention is a work mounting base of a router processing machine in which a decorative sheet and a base plate on which a design drawing coupled to the front surface of a game board in the game board is overlapped with each other. A hole on a game board used when a cutting tool of a router machine cuts a through hole from a game board side to a decorative sheet side to form a game board in a state of being fixed on the surface plate In the base plate for drilling, in order to escape the cutting tool when penetrating the game board and receive the decorative sheet around the through hole so that it does not peel off from the game board, a through hole is formed in the base board. The main feature is that it is provided in advance corresponding to the hole. The escape hole may be formed in the same shape as the through hole, or the escape hole may be formed as a hole penetrating the floor plate.

  The base plate for drilling processing of a game board according to the present invention is a work mounting base of a router processing machine in which a decorative sheet and a base plate on which a design drawing coupled to the front surface of a game board in the game board is overlapped with each other. When the through hole is drilled in the game board with the cutting tool of the router machine while being fixed on the surface plate, the cutting tool used when the escape hole provided in the base plate penetrates the game board is used. As it escapes and receives the decorative sheet around the through-hole and prevents it from peeling off from the game board of the decorative sheet, it can prevent the decorative sheet around the through-hole from peeling off from the game board, and the cutting edge of the cutting tool is placed on the base plate In addition to being able to improve the durability of the cutting tool without touching it, in addition to the through hole of the game board, even when a recess that does not reach the decorative sheet is formed in the game board, There is no need to change the processing procedure, and it is possible to appropriately drill through holes and dents with fewer steps. Further, after drilling, the cutting waste that has entered between the decorative sheet and the game board can be removed manually. There is an advantage that the game function parts can be attached to the front surface of the game board at an appropriate height without performing the work to be removed. If the escape hole is formed in the same shape as the through hole, there is an advantage that it is possible to best prevent the decorative sheet around the through hole from being peeled off from the game board. If the escape hole is formed as a hole penetrating the floor plate, there is an advantage that cutting waste generated in the process of drilling the through hole by the cutting tool can be released below the floor plate.

  In FIG. 2, as shown in step 201, the decorative sheet 1 is formed by multicolor printing using ordinary paint on the entire back surface of the front panel 1a made of a transparent synthetic resin sheet having light permeability. The fixing sheet 1b such as Kent paper is bonded to the entire back surface of the design drawing.

  This decorative sheet 1 is formed in a substantially congruent square shape with the game board 2 made of veneer or the like shown in step 202 and is integrally coupled to the game board 2.

  In order to connect the decorative sheet 1 and the game board 2, for example, as shown in step 203, the back surface of the game board 2 is mounted on a fixed plate and is heated to a predetermined temperature by an electric heater (not shown). By pressing the outer movable plate against the front surface of the game board 2 mounted on the fixed plate (not shown) with a predetermined pressure, the game board 2 is heated and pressurized for a predetermined time, thereby drying the front surface of the game board 2. .

  After an emulsion type adhesive 3 such as vinyl acetate is uniformly applied to the entire front surface of the game board 2 in a state where latent heat is generated by this heating, the adhesive is semi-dried. 3, while the back surface of the fixing sheet 1 b of the decorative sheet 1 is overlapped, the game board 2 on which the decorative sheet 1 is overlapped is moved to a movable plate outside the figure and a fixed plate outside the figure. And by applying pressure in a direction facing each other on the front surface side of the decorative sheet 1 and the back surface side of the game board 2 by throwing and bonding with the adhesive 3, the game board 2 And the decorative sheet 1 are integrally coupled with the fixing paper 1b interposed therebetween to obtain a game board 4 in which the decorative sheet 1 and the game board 2 are integrally coupled.

  Then, as shown in step 205, positioning holes 5; 6 are formed in the game board 4 by cutting using a drill 7; 8 from the front side of the game board 4, that is, the decorative sheet 1 side. In this cutting process, an automatic drilling operation using a multi-axis drilling machine is performed. At the same time as forming the positioning holes 5; 6, guide rail mounting holes (not shown) using a drill (not shown) are also provided from the decorative sheet 1 side. It is usual to form. These positioning holes 5; 6 are diagonally arranged on both sides of the corner of the game board 4 with one diagonal line L1 as a boundary so as to be hidden by game function parts (not shown) attached to the front surface of the game board 4.

  Thereafter, as shown in FIG. 3, the game board 4 is overlaid on the floor board 9 so that the game board 4 is turned over and the front surface of the decorative sheet 1 is overlaid on the front surface of the floor board 9.

  One positioning hole 5 of the positioning holes 5; 6 formed in the game board 4 is located at the intersection of the distance D1 from the upper edge of the game board 4 and the distance D2 from the side edge of the game board 4. The other positioning hole 6 is located at the intersection of the distance D3 from the lower edge of the game board 4 and the distance D4 from the side edge of the game board 4, and the dimensions of the distances D1 to D4 are D1 <D2 <. The relationship is D4 <D3.

  In addition, the floor board 9 is formed in a substantially congruent square shape with the game board 4 by either a thermosetting synthetic resin such as Bakelite (trademark) or a chemically treated wood such as acetylation as a material having low hygroscopicity. . A positioning hole 10; 11 having the same shape as the positioning holes 5; 6 of the game board 4 is formed coaxially in the floor board 9, and a cutting such as a drill or an end mill described later is provided on the game board 4 from the back side. A clearance hole 12 having the same shape as a plurality of through-holes 16 to be described later that are cut using the tool 17 is formed coaxially.

  The positioning holes 10; 11 formed in the floor board 9 are diagonally arranged on both sides of the corner of the floor board 9 with one diagonal line L2 as a boundary, and like the positioning holes 5; 6 of the game board 4, The positioning hole 10 is located at the intersection of the distance D1 from the upper edge of the base plate 9 and the distance D2 from the side edge of the base plate 9, and the other positioning hole 11 is located between the distance D3 from the lower edge of the base plate 9 and the base plate 9. It is located at the intersection with the distance D4 from the side edge, and the gaming board 4 can be positioned and mounted on the floor board 9 without making a mistake in the vertical relationship due to the relationship between these dimensions D1 to D4.

  According to the best mode, when the game board 4 turned upside down is overlapped with the floor board 9 and the plurality of through holes 16 are cut from the back side of the game board 4, that is, the game board 2 side, it is called a router processing machine. Since a drilling machine having a numerical control function is used, as shown in FIG. 1, a plurality of positioning holes 10; 11 of the base plate 9 are projected on a surface plate 13 as a work mounting base of the router machine. After the base plate 9 is mounted on the surface plate 13 of the router processing machine, the positioning holes 5; 6 of the game board 4 are opened with the game board 4 turned upside down. By fitting and mounting the positioning pins 14; 15 of the router machine projecting upward from the positioning holes 10; 11 of the floor board 9 from above, the front side of the game board 4, that is, the decorative sheet 1 is superimposed on the floor board 9, Router processing the periphery of the game board 4 from above By pressing in an unillustrated bracket is fixed to the base 13 in a state of superposition of both the game board 4 and decking 9.

  In this state, by driving the router processing machine based on preset numerical data, the game board 4 that is positioned and fixed on the surface plate 13 of the router processing machine with the floor plate 9 interposed therebetween is inserted into the through hole. 16 is formed by cutting with a cutting tool 17 of a router machine from the surface opposite to the side on which the floor plate 9 is overlapped, that is, the back surface side of the game board 4.

  When the formation of the through hole 16 is completed, as shown in FIG. 4, the game board 4 is removed from the floor plate 9 mounted on the surface plate 13 of the router processing machine, whereby the game board 4 has a plurality of through holes 16. Is formed. After that, the game board 4 is turned over again from the state shown in FIG. 4, and the front side of the game board 4, that is, the decorative sheet 1 is directed upward and conveyed to the next process.

  At the transport destination, on the front surface of the game board 4, a band attachment hole (not shown) for a band (not shown) (guide for guiding a game ball bounced from the ball launcher into the game area of the game board) is provided. In addition to using the through-holes 16 for mounting, various types such as unillustrated center role, windmill, start port, general winning port, large winning port, out port, side lamp, prize ball lamp, stop lamp, etc. By attaching the game function parts, the gauge board of the pachinko machine is completed.

  Therefore, according to the best mode, since the floor plate 9 made of a material that is resistant to changes in humidity and temperature is used, the floor plate 9 is less warped due to changes in humidity and temperature. When the decorative sheet 1 of the board 4 is overlaid on the floor board 9, the decorative sheet 1 and the floor board 9 are in close contact with each other. Therefore, when the cutting edge of the cutting tool 17 passes through the decorative sheet 1, the decorative sheet 1 is appropriately received by the floor plate 9, so that the decorative sheet 1 around the through hole 16 can be reliably prevented from turning up, Moreover, even when the recess 18 is formed on the back side of the game board 4, it can be appropriately drilled in the same process as the formation of the through hole 16.
