BACKGROUND OF THE INVENTION
The present invention relates to a drilling method for forming a through hole for attaching a game functional component to a game board such as a pachinko machine using a game ball or a slot machine using a medal.
[0002]
[Prior art]
The game board of the pachinko machine has a through-hole for attaching a game functional component to the back of the game board, such as a plywood board, and a cell sheet with a design drawing drawn on the back. It has a recess used for positioning a functional component attached to the back surface.
[0003]
[Problems to be solved by the invention]
In the case of forming the through holes and depressions on the game board with drilling machine called router pressurized coater, and drilling from the front side, that the cell sheet side of the game board through hole, the game board depressions backside In other words, if drilling is performed from the game board side, the drilling process becomes two steps, which is economically disadvantageous.
[0004]
6 For this reason, when drilling in one step from the back side of the game board 42 through holes 40 and recesses 41, the tool 43 such as a drill or end mill router pressurized Koki is a game When the board 42 is pulled out to the front side, the cut edge of the cell sheet 44 may be peeled off from the game board 45 and turned up. When this turning-up occurs, scraps 46 during processing such as sawdust enter between the turned-up cell sheet 44 and the game board 45, and the periphery of the through hole 40 of the cell sheet 44 is the front surface of the game board 42. Stays raised to the side. When this cell sheet 44 is raised and game functional parts such as tulips, center bonuses, winning holes, and attackers not shown are attached to the front of the game board 42, the height of the game functional parts is unreasonably high. In addition, game function parts may be distorted.
[0005]
If the gaming functional parts are unreasonably high, there is a disadvantage that the glass is damaged when the gaming board 42 is assembled to the machine frame attached to the island of the pachinko parlor and the glass of the machine frame is closed. When the game functional part has a movable part, the movable part may malfunction due to the distortion. Therefore, after punching, the scrap 46 that has entered between the cell sheet 44 and the game board 45 is manually created. There is a limit to reducing costs.
[0006]
In order to eliminate such inconvenience, a jig (not shown) called a base plate in which a relief hole of the same shape is formed at the same position as the through hole formed in the game board 42 is superimposed on the cell sheet 44 of the game board 42. It is also possible to perform drilling from the back side of the game board 42. However, each time the game board model to be drilled is changed, the floor board before the model change is routed. Remove from the mounting base of data pressurized Koki, that attach the decking after the change the model to the mounting base of the router pressurized Koki, it is necessary to setup changes. Moreover, since the method of co-processed at a time several sheets of the game board with a single router pressurized coater is employed, the number of sheets of decking required per single router pressurized Koki is A, Lou and the number of data pressurized Koki and B, and the number of models the game board and C, the floor plate is required is the number of a × B × C = D, production cost of decking also Kasami, as it suddenly hard to adopt is there.
[0007]
Accordingly, the present invention seeks to provide without using a jig such as decking, the game board hole drilling method capable of preventing the curling up of the cell sheet around the through-hole.
[0008]
[Means for Solving the Problems]
The game board drilling method according to the present invention is a method in which a cell sheet has a design layer on the back surface of a light-transmitting surface layer and a fixing layer on the back surface of the design layer, and surrounds a through hole for attaching a game function component. Lines penetrate the front and back of the surface layer and are engraved on the surface layer, and the inner and outer portions of the surface layer surrounded by the cut line are connected by the fixing layer, and the fixing layer of this cell sheet is the front surface of the game board A game board made of a game board and a cell sheet is formed by bonding to a game board, and a through hole for attaching a game functional part to the game board is formed by a router processing machine. The game board is fixed to the surface plate of the router machine in a state where the surface layer of the cell sheet is in contact with the support protrusion other than the portion where the through hole is formed in the surface plate of the router machine. After tool over data processing machine escapes space when penetrating the game board from above downward is formed between the game board and the surface plate, the through-hole on the game board while rotating the tool of the router machine It is characterized by being formed so as to be bordered by a cut line. According to the game board drilling method of the present invention, when the game board is fixed to the surface plate of the router processing machine, the surface layer of the cell sheet is other than the portion where the through hole is formed in the surface plate of the router processing machine. When the game board is fixed to the surface plate of the router machine while being mounted on the support protrusions, the clearance space when the tool of the router machine penetrates the game board from the upper side to the lower side is defined as the game board. Since it is formed between the board and the board, there is no need to use a jig to change for each type of game board called a floor board in which a relief hole of the same shape is formed at the same position as the through hole formed in the game board Also, since the cut line penetrates the front and back of the surface layer and is carved on the surface layer, when the tip of the tool of the router processing machine passes through the cell sheet, the inner part surrounded by the cell sheet cut line is the outer part From the cut line It is possible to prevent the cell sheet from turning up around the through-hole, and the router processing machine tool is rotated so that the inside of the game board is surrounded by the cut line of the game board from the game board. Since the above-mentioned through hole is drilled, even if a recess is formed on the back side of the game board, it is not necessary to change the drilling procedure, and the recess and the through hole can be appropriately drilled in a small number of steps. In the cell sheet at the time before being joined to the game board, the inner and outer portions of the surface layer surrounded by the cut line engraved on the surface layer through the front and back of the surface layer are connected by the fixing layer, so the game The cell sheet at the time before being joined to the board can be shaped like a sheet.

DETAILED DESCRIPTION OF THE INVENTION
1 to 3 show a first embodiment. In FIG. 1, as shown in step 101, a cell sheet 1 is a design layer 1b formed by multicolor printing using a normal paint on the entire back surface of a surface layer 1a made of a transparent synthetic resin sheet having optical transparency. A fixing layer 1c such as Kent paper is adhered to the entire back surface of the design layer 1b, and a cut line 1d is formed on the surface layer 1a. As shown in FIG. 2, the cut line 1d is positioned along the outside of the through hole 27 that is drilled in the game board 9 with a tool such as a press cutter after the cell sheet 1 is formed. A hole corresponding to the through hole 27 is drawn so as to penetrate the front and back of the surface layer 1a. The inner part and the outer part of the surface layer 1a surrounded by the cut line 1d are connected by the fixing layer 1c.
[0010]
Returning to FIG. 1 again, the cell sheet 1 is formed in a substantially congruent square shape with the game board 2 constituted by a plywood or the like shown in step 102 and is integrally coupled to the game board 2.
[0011]
In order to connect the cell sheet 1 and the game board 2, for example, as shown in step 103, the back surface of the game board 2 is mounted on the fixed plate 3 and the movable plate 5 heated to a predetermined temperature by the electric heater 4. Is pressed against the front surface of the game board 2 mounted on the fixed plate 3 with a predetermined pressure, thereby heating and pressurizing the game board 2 for a predetermined time, thereby drying the front surface of the game board 2.
[0012]
As shown in step 104, the emulsion type adhesive 6 such as vinyl acetate is uniformly applied to the entire front surface of the gaming board 2 in a state where latent heat due to this heating is retained, and then the process is changed to a step 105. As shown, the back surface of the fixing layer 1c of the cell sheet 1 is overlaid on the adhesive 6, while the game board 2 on which the cell sheet 1 is overlaid is fixed to the movable plate 7 having no heater as shown in step 106. By sandwiching with the plate 8 at a predetermined pressure and pressurizing for a predetermined time, a pressure in a direction facing each other is applied to the front side of the cell sheet 1 and the back side of the game board 2, and the game is performed by throwing connection with the adhesive 6. The game board 9 in which the cell sheet 1 and the game board 2 are integrally joined is obtained by integrally joining the board 2 and the cell sheet 1 with the fixing layer 1c interposed therebetween.
[0013]
Then, as shown in step 107, positioning holes 12 and 13 are formed in the game board 9 from the front side of the game board 9, that is, from the cell sheet 1 side by drilling using the drills 10 and 11. In this drilling process, an automatic drilling operation using a multi-axis drilling machine is performed. At the same time as forming the positioning holes 12 and 13, a guide rail mounting hole (not shown) using a drill (not shown) is also provided from the cell sheet 1 side. It is usual to form. These positioning holes 12 and 13 are arranged at corners of a pair of diagonal positions of the game board 9 so as to be hidden by game function parts (not shown) attached to the front surface of the game board 9.
[0014]
Next, as shown in step 108, the gaming board 9 that has been drilled by the multi-axis drilling machine is removed from the multi-axis drilling machine, and the positioning holes 12 and 13 of the gaming board 9 are defined as workpiece mounting bases of the gauge press machine. After the game board 9 is mounted on the surface plate 14 of the gauge press machine, the ram 17 of the gauge press machine is driven after the game board 9 is mounted on the surface plate 14 of the gauge press machine. The press gauge plate 18 is lowered, and the pilot holes 20 are pushed through the front side of the game board 9, that is, the front surface of the cell sheet 1 and the game board 2 with a number of punches 19 protruding from the lower surface of the press gauge plate 18. Form.
[0015]
Thereafter, as shown in step 109, with the gaming board 9 removed from the gauge press machine turned upside down, the positioning of the positioning holes 12 and 13 of the gaming board 9 is mounted on a router machine that is a drilling machine having a numerical control function. The game board 9 is mounted on the surface plate 21 of the router processing machine by fitting and mounting a plurality of positioning pins 22 and 23 projecting on the surface plate 21 as a base from above. The surface plate 21 of this router processing machine has support protrusions 24 and 25 at portions other than a portion where a through hole 27 described later is formed, and the cell sheet 1 of the game board 9 is placed on these support protrusions 24 and 25. In the mounted state, the game board 9 is mounted on the router processing machine, and the game board 9 is turned upside down by pressing the peripheral edge of the game board 9 from above with a bracket (not shown) of the router processing machine. It is fixed to the board 21. The height of the support protrusions 24 and 25, between the game board 9 and platen 21, the relief space when the tool 26, such as a drill or end mill router pressurized coater is penetrate the gaming board 9 formed is doing.
[0016]
In this state, by driving the router processing machine based on preset numerical data, the game board 9 positioned and fixed on the surface plate 21 of the router processing machine is attached to the game board 9 from the back side of the game board 9. Through holes 27 and depressions 28 are formed by drilling with the tool 26.
[0017]
When the formation of the through holes 27 is completed, the game board 9 is removed from the router processing machine, whereby a plurality of through holes 27 are bordered on the cut line 1d of the cell sheet 1 as shown in FIG. Is formed. After that, the game board 9 is turned over again so as to be in the state shown in FIG. 3, and the front side of the game board 9, that is, the cell sheet 1 is directed upward, and is conveyed to the next step.
[0018]
At the transport destination, a game nail (not shown) is driven into the front surface of the game board 9 while a band (guide for guiding a game ball bounced from the ball launcher into the game area of the game board) outside the figure is described above. is attached by using the non-illustrated band attachment hole, an unillustrated center won game by using the through hole 27, a windmill, starting opening, generally winning opening, a special winning opening, out port, side lamps, By attaching various game function parts such as prize ball lamps and stop lamps, the pachinko machine gauge panel is completed.
[0019]
According to this embodiment, since the cut line 1d is formed on the surface layer 1a of the cell sheet 1, the inside of the fixing layer 1c surrounded by the cut line 1d of the surface layer 1a or the design layer 1b is inseparably held in an integral manner. The sheet 1 can be shaped like a sheet. Further, by punching a through hole 27 in the game board 9 in which the cell sheet 1 having the cut line 1d formed on the surface layer 1a is coupled to the game board 2, the cell 26 is removed when the tip of the tool 26 passes through the cell sheet 1. The sheet 1 is separated from the cut line 1d, and it is possible to reliably prevent the cell sheet 1 from turning up around the through-hole 26, and even when the recess 28 is formed on the back side of the game board 9, it is necessary to change the drilling procedure. In addition, the recess and the through hole can be appropriately drilled with a small number of processes.
[0020]
4 to 5 show a second embodiment. In this embodiment, as shown in step 401 of FIG. 4, the cell sheet 1 is formed by penetrating a hole 1 e corresponding to a through hole 27 (see step 409) in which a hole is formed in the game board 9 (see step 406). Thus, the cell sheet 1 is joined to the game board 2 shown in step 402 through the processes of steps 403 to 406 to form the game board 9. The game board 9 is formed with a through hole 27 and a depression 28 through steps 407 to 409. When the formation of the through hole 27 is completed, the game board 9 is removed from the router machine shown in step 409, whereby a plurality of through holes 27 are formed in the game board 9 as shown in FIG. It is formed to be edged.
[0021]
According to this embodiment, since the hole 1e is formed in the cell sheet 1, the hole 1e can be easily formed by punching the hole 1e with a press or the like. Further, in addition to the first embodiment, since the synthetic resin component constituting the surface layer 1a of the cell sheet 1 is not included in the waste from the router processing, the exhaust gas when the waste is incinerated is released to the atmosphere as it is. However, the problem of pollution caused by incineration of synthetic resin or the like can be prevented. Further, when the thickness of the adhesive 6 to be transferred to the game board 2 in step 404 in FIG. 1 is set to be thin and the cell sheet 1 is pressed against the game board 2 in step 406, the adhesive 6 is transferred to the cell sheet 1. If it does not protrude from the hole 1e to the surface layer 1a side, the disadvantage that the adhesive 6 adheres to the movable plate 7 can be eliminated.
[0022]
In the above-described embodiment, a pachinko machine using a game ball has been described as an example. However, the present invention can be applied to a slot machine that uses medals by replacing functional parts attached to an intermediate product.
