Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial application field> The present invention relates to a method for manufacturing a machine frame for a pachinko machine in which upper ends of left and right side plates are connected by a top plate and lower ends are connected by a bottom plate. .

<Conventional technology> Conventionally, in order to manufacture a machine frame for a pachinko machine, a rectangular plate having necessary outer dimensions as a side plate, a top plate, a bottom plate, and a curtain plate is cut from a so-called single plate or a thick plywood, Each of the plates was cut and assembled into a frame. And it was common that the frame-like body assembled in this manner was not coated. In the case of coating, since a heat-resistant synthetic resin plate is adhered to the surface of the curtain plate as a coating plate, it is difficult to perform dip coating, and therefore brush coating or spray coating has been performed.

<Problems to be Solved by the Invention> However, if the machine frame is not painted, expansion and contraction and deformation due to moisture tend to occur.

In the case of applying the coating, the conventional method takes much time and causes uneven coating.

Further, in the pachinko machine line 2 in which a large number of pachinko machines 1 are installed, as shown in FIG. 14, the bottom plate 3 of the machine frame is similar to the shelf plate 4 so that dropped cigarettes, ash and spilled drinks are provided. In addition, when the upper surface of the shelf plate 4 is wiped with a rag, the rag comes into contact with the front end of the bottom plate 3 of the machine frame and gets wet.

If the bottom plate 3 of the machine frame is conspicuous, a dirty impression is given to the player, and the machine frame which is wet by the moisture of the rag expands and contracts or deforms.

Therefore, there has been a demand for a method of manufacturing a machine frame for a pachinko machine which has a high production efficiency and which can solve the above-mentioned disadvantages of the machine frame.

<Means for Solving the Problems> The present invention has been proposed in view of the above, a step of cutting a plywood to form a rectangular plate having the required external dimensions as a side plate, and cutting the plywood as a top plate A step of forming a rectangular plate having the required external dimensions; a step of cutting the plywood to form a rectangular plate having the required external shape as a bottom plate; A process of forming a required shape as a board and a bottom plate; a process of pressure-bonding a decorative plate having a masking sheet in close contact with the surface of the plywood in a releasable state; A step of forming one end face of the bottom plate in black, and a step of connecting the upper ends of the left and right side plates separated by a top plate and connecting the lower ends of the side plates by the bottom plate. Black painted surface A step of assembling the frame in a state protruding from the side plate, a step of fixing a curtain plate to a lower end of a front opening of the frame, and a step of dip-coating the frame with a curtain in a light-colored paint. It is another object of the present invention to provide a method for manufacturing a machine frame of a pachinko machine, comprising a step of removing a masking sheet of a curtain after drying.

<Example> Hereinafter, an example of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 4, the frame 11 of the pachinko machine 1 has upper and lower side plates 12a and 12b connected by a top plate 13 and lower ends of the side plates 12a and 12b connected by a bottom plate 14. It comprises a machine frame 15 and a frame-shaped front frame 17 which is attached to the front opening of the machine frame 15 by hinges 16, 16 so as to be openable and closable. The width and the vertical length of the machine frame 15 and the front frame 17 are different between the Kanto frame and the Kansai frame, and the Kanto frame is larger than the Kanto frame. Specifically, the front frame 17a of the Kansai frame
The size of the front frame 17b of the Kanto frame has a width of 516 mm and a vertical length of 711 m, with a width of 525 mm and a vertical length of 719 mm.
m. Note that the thickness of the front frame 17 and the size of the frame-shaped opening are common to both the Kanto frame and the Kansai frame, and the size of the storage step 18 such as a metal frame formed at the opening edge of the opening is also common.
However, as shown in FIG. 6, the positions of various holes formed in the front frame 17 are slightly different between the Kanto frame and the Kansai frame.

In the case of finally manufacturing two types of front frames 17a and 17b having different sizes, in this embodiment, a semi-processed material 19 that can be used for either size is first created.

In order to make the semi-processed material 19, as shown in FIG.
A rectangular plate 20 having necessary outer dimensions is formed as 17a and 17b, and a frame-shaped opening 21 is cut out from the rectangular plate 20 to form a cutout plate member 22. Specifically, by cutting a cross plywood with a thickness of 8.75 mm, the width is 530 mm and the vertical length is 725 mm
The rectangular plate 20 is provided with an opening 21 having a width of 420 mm and a vertical length of 535 mm. The opening 21 is located 65 mm from the upper edge, 55 mm from the left edge, 55 mm from the right edge, and 125 mm from the lower edge.

When the opening 21 is opened in this way, a rectangular remnant 23 which is slightly smaller than the opening 21 and which is long vertically is generated. Therefore, two pieces of the remaining material 23 are stacked and bonded while pressing with an adhesive to form a plate material 24 having a thickness of 17.5 mm. The plate material 24 is cut and the top plate 13 and the bottom plate 14 of the machine frame 15 are cut. A rectangular plate having the required external dimensions is prepared as the curtain plate 25, or is used as a material for the back rail 26, the reinforcing member 27, etc., and the end material is a packing material 28 as shown in FIG. And In the embodiment, the top plate 13 has a width of 70 mm, the bottom plate 14 has a width of 90 mm,
Since the curtain plate 25 has a width of 76 mm and the back rail 26 has a width of 20 mm, a plurality of the rectangular plates are cut from one plate member 24 as shown in FIGS.

Then, on the top plate 13, the above-described rectangular plate is subjected to required processing such as the cutout portion 29 and the counterbore portion 30 to have a predetermined shape.

On the bottom plate 14, a shallow recess 14 'is formed in one surface of the rectangular plate along the longitudinal direction, and one end surface is formed into a curved surface, and the one end surface is painted in black. To form the bottom plate 14. When one end surface of the bottom plate 14 is painted black, any type of painting means may be used. However, a roller having a groove having a shape corresponding to the shape of the one end surface of the bottom plate 14 (not shown) It is also possible to apply black paint in advance to the groove of the roller, and to apply the coating by bringing one end surface into contact with the groove of the roller when the bottom plate 14 is fed by the feeder.

When the curtain plates 25 are to be prepared, as shown in FIG. 10, a heat-resistant synthetic material is used in which a vinyl sheet or the like is previously attached as a masking sheet to the surface of the above-mentioned plate material 24 in a detachable state with an adhesive. The decorative plate 31 such as a resin plate is bonded by pressure. After that, a rectangular plate having a necessary outer dimension as the curtain plate 25 is cut, and this rectangular plate is set as the curtain plate 25.

As described above, in the present embodiment, two pieces of the remaining material 23 are bonded to each other to form the plate material 24.
Most of 23 can be used without waste, and the yield can be improved.

In addition, when creating the cutout plate material 22, the width was set to 530 mm, if the left and right edges were cut to 2.5 mm, the predetermined width of the Kansai frame front frame 17a was 525 mm, while the left edge was 2.5 m.
m, if the right edge is cut by 11.5 mm, the width becomes 516 mm, which is the predetermined width of the front frame 17b for the Kanto frame. Also, the vertical width of the cutout plate material 22 was set to 725 mm, because when the upper and lower edges were cut to 3 mm, the predetermined vertical length of the front frame 17a for Kansai frame 17a was 719 mm, the upper edge was cut 11 mm, and the lower edge was cut 3 mm. This is because the predetermined vertical length of the front frame 17b for the Kanto frame is 711 mm.

Next, in order to create a connecting plate 32 for bonding to the cutout plate 22 described above, a lower plate 32a, an upper plate 32b, a left plate 32c, and a right plate are cut by cutting a cross plywood having a thickness of 8.75 mm. Three
2d, and the lower plate 32a, the upper plate 32b, the left plate 32c, and the right plate 32d are connected and fixed in a substantially square shape, so that the cutout plate material 22 is formed.
A frame having an opening 33 smaller than the opening 21 of FIG. The lower plate 32a has a left-right length of 410 mm and a vertical length of 143 m
m, upper plate 32b is 410 mm in left and right length, 77 mm in vertical length, left plate 3
Both the 2c and the right plate 32d have a width of 60 mm and a vertical length of 725 mm.
Therefore, when the lower ends of the left plate 32c and the right plate 32d are connected by the lower plate 32a, and the upper ends of the left plate 32c and the right plate 32d are connected by the upper plate 32b, the width is 530, like the cutout plate material 22.
mm and a vertical frame with a length of 725 mm and a width of 410 mm
Thus, an opening 33 having a vertical length of 505 mm is formed.

In order to bond the cut-out plate material 22 and the connecting plate material 32 created as described above into one piece of the semi-processed material 19, apply a woodworking adhesive to the bonding surface, and then apply the cut-out plate material 22 and the connecting plate material. Press for a while with 32 superimposed. The semi-processed material 19 created in this way can be used commonly for both the Kansai frame and the Kanto frame, and is thus kept in stock in this state.

Then, the semi-processed material 19 is cut to a predetermined size of the Kansai frame or the Kanto frame by cutting the four circumferences of the upper, lower, left and right edges according to the order quantity by a predetermined width. In other words, to finish the Kanto frame, the left edge is 2.5 mm, the right edge is 2.5 mm, the upper edge is 3.0 mm, the lower edge
Width is 525mm and vertical length is 719m by cutting 3.0mm
Finish to m. On the other hand, when finishing to the Kanto frame, the left edge is 2.5 mm, the right edge is 11.5 mm, the upper edge is 11 mm, the lower edge is 3.0 mm, and the width is 516 mm and the vertical length is 711 mm. When such processing is completed, the decorative plate 34
Is pressure-bonded to the surface, and the remaining processing such as cutting and drilling is performed to complete the final front frame 17.

In addition, as shown in FIG. 12, the cutout plate 22 is used as a middle plate, the connecting plate 32 is used as a rear material, and the decorative plate 34 is attached to the surface of the cutout plate 22, or as shown in FIG. As shown in the connecting plate 32
May be used as a middle plate and the cutout plate 22 as a rear plate, and the decorative plate 34 may be attached to the surface of the connection plate 32.

The decorative plate 34 may be made of any material as long as it has a function of decorating and protecting the surface of the front frame 17. In the embodiment shown in the drawings, the decorative plate 34 is a typical heat-resistant synthetic resin plate material. Using a melamine plate that is difficult to stick and has heat resistance, lower decorative piece 34a, upper decorative piece 34b, left decorative piece 34c,
Cutout plate 2 by connecting the right decorative piece 34d in a substantially square shape
An opening 35 larger than the second opening 21 is formed. The lower decorative piece 34a used for the Kansai frame has a left and right length of 525 mm and a vertical length of 117 mm, the upper decorative piece 34b has a left and right length of 441 mm and a vertical length of 58 mm, and the left decorative piece 34c and the right decorative piece 34d are both The width is 42mm and the vertical length is 602mm. Therefore, in the case of the decorative plate 34 used for the Kansai frame, the opening having a width of 441 mm and a height of 544 mm
35 is formed. On the other hand, the lower decorative piece 34a used for the Kanto frame
The left and right length is 516 mm and the vertical length is 117 mm, the upper decorative piece 34b is the left and right length 440 mm and the vertical length is 50 mm, the left decorative piece 34c and the right decorative piece 34d are both 38 mm wide and 594 mm in vertical length It is. Therefore, in the case of the decorative plate 34 used for the Kanto frame, the width is 44
An opening 35 having a height of 0 mm and a height of 544 mm is formed.

In order to attach the decorative plate 34 of the above size to the surface of the semi-processed material 19, first, the lower decorative piece 34a, the upper decorative piece 34b, and the left decorative piece 34
c, and the right decorative piece 34d are arranged on a flat work table in a substantially square shape and without any gaps at the seams, and each decorative piece 34a,
Adhesive tape is applied to the joints of 34b, 34c and 34d and four decorative pieces 3
4a, 34b, 34c, 34d are temporarily fixed and integrated. Then, an adhesive is applied to the surface of the semi-processed material 19, and the above-described decorative plate 34 is placed on the semi-processed material 19 with the adhesive tape facing up and adhered. Note that the adhesive dries and the decorative plate 34 is
Press for a while with a pressing device until it is securely adhered to the surface of. Even when the decorative pieces are bonded under pressure in this manner, since the joints between the decorative pieces are closed with the adhesive tape, the adhesive is not pushed out from the joints to the front side of the decorative plate.

Once the decorative plate 34 has been pressure bonded, peel off the adhesive tape,
Chamfers four rounds of upper, lower, left and right edges. In addition, the cutout plate material 22
Is larger than the opening 33 of the connection plate 32,
A step is formed at the inner peripheral edge of the opening of the semi-processed material 19, and this step is used as it is as the storage step 18 such as a metal frame.

Then, when the above-mentioned processing is completed, processing is performed on the opening portion 36 into which a part of the hitting ball launching device enters, the hole 37 through which the game ball passes, etc. (Not shown) and work on the front frame
Complete as 17.

Next, in order to create the machine frame 15, the side plate 12 is cut by cutting a parallel plywood having a thickness of 17.5 mm in which the grain is aligned in the same direction.
A rectangular plate having the required external dimensions is created as a and 12b, and a predetermined counterbore 38
a, 12b.

Then, the side plates 12a, 12b thus created are arranged on the left and right at a predetermined interval, and the lower ends of the left and right side plates 12a, 12b are arranged such that the black one side end surface of the bottom plate 14 projects forward by the bottom plate 14. The upper end is connected to each other by the top plate 13 to form a rectangular frame, and the curtain plate 25 is fixed to the lower end of the front opening portion of the frame with the decorative plate 31 facing the front side. Then, the back rail 26 is struck on the upper edge of the back surface of the curtain plate 25 and the reinforcing material 27 is struck at the end to reinforce.

Next, the machine frame 15 assembled in this manner is immersed in an immersion tank (not shown) filled with a light-colored paint such as woodwork varnish, and the whole is painted. By applying such a dip coating, it is possible to paint the entire surface without unevenness and with a single operation,
Not only the finish is good, but also the work efficiency is good. In addition,
Since the masking sheet is in close contact with the curtain plate 25 where the paint is not to be adhered, the masking sheet may be peeled off after drying. Also, on the black one side end surface of the bottom plate 14, even if a light-colored paint is applied by dip coating, it looks black, rather the thickness of the paint layer increases,
Increases protective effect.

The front frame 17 is hinged to the machine frame 15 created as described above.
When it is opened and closed by 16, 16, it becomes the frame 11 of the pachinko machine 1.

<Effects of the Invention> As described above, according to the present invention, the entire machine frame is uniformly coated, so that expansion and contraction and deformation due to moisture hardly occur. Therefore, the inclination of the pachinko machine is not disturbed, and the adjustment of the payout rate by the nail adjustment is close to the planned value.

Further, the machine frame manufactured by the manufacturing method according to the present invention includes:
Since the end face of the bottom plate is painted black, even if it is close to the shelf plate, the fallen cigarette ash and the spilled drink are hard to adhere and the dirt is not conspicuous. Furthermore, even if the rag contacts the front edge of the bottom plate of the machine frame when the upper surface of the shelf is wiped with a rag,
Since the light-colored paint by immersion painting is applied on the black paint to be protected thickly, there is no possibility that the moisture of the rag will permeate the bottom plate. Therefore, it does not expand or contract even when wet.

Further, in the present invention, a decorative plate in which a masking sheet is preliminarily adhered to the surface of a curtain plate is pressure-bonded, and then dip coating is performed, so that the masking sheet is not displaced and excess paint is applied to the surface of the coated plate. Can be effectively prevented from being attached, and the production efficiency is high.
