Description

  The present invention relates to a game board manufacturing facility, and more particularly to a technique for manufacturing a game board using a plate-like member formed of a light-transmitting material.

  In gaming machines, game boards with a cell film attached to the surface of the veneer have been mainstream, but in recent years, the cell film is attached to the surface of a plate member having light transmittance, and an illumination device on the back side. There has been proposed a game board in which a computer is installed (Patent Document 1).

JP-A-10-179854

  By the way, the light-transmitting plate-like member is made of synthetic resin such as acrylic, so it is easy to cause expansion and deformation due to changes in the environment such as temperature, and the defective product with the cell film sticking position shifted is shipped as it is. There was a risk of doing so.

  Accordingly, an object of the present invention is to prevent a defective product from being shipped accidentally when a game board is manufactured.

The game board manufacturing equipment of the present invention made to achieve such an object includes at least a pasting means for pasting a cell film on the back side of a plate-like member formed of a light-transmitting material, and the cell film And determining means for determining whether or not the plate-shaped member is correctly attached to the plate-like member, and further including the following configuration.
(1A) The cell film is printed in consideration of a design expressed by a combination of a transparent region and a non-transparent region or a color combination in the non-transparent region, and at least partially distinguishes it from the surrounding design. The determination reference mark is printed with the non-transparent ink of the color to be obtained.
(1B) A cutting means for cutting the determination opening with respect to a predetermined position of the cell film is provided between the sticking means and the determination means, and the cutting means is used for cutting the determination opening. A cutting positioning means for positioning the plate-like member so as to remove at least a part of the determination reference mark into a predetermined shape on the assumption that the cell film is correctly attached to the plate-like member. It is equipped with.
(1C) The determination unit includes an imaging unit that captures an image from the surface side of the plate-like member, and performs the pass / fail determination based on a remaining state of the determination reference mark in an image captured by the imaging unit. Be configured as.

  According to the game board manufacturing facility of the present invention, the cutting positioning means removes at least a part of the determination reference mark into a predetermined shape on the premise that the cell film is correctly attached to the plate-like member. In the same manner, the plate-like member is positioned. As a result, the cell film is correctly attached to the plate-like member (hereinafter referred to as “non-defective product”) and the cell film is attached to the plate-like member in a shifted state ( (Hereinafter referred to as “defective product”), the remaining state of the judgment reference mark when the judgment opening is cut by the cutting means is different, and a difference occurs in the images taken by the imaging means. Therefore, the determination means can determine whether the determination reference mark is a non-defective product or a defective product depending on whether or not the determination reference mark is in a predetermined remaining state (the remaining state when the cell film is correctly attached). . Note that the “predetermined remaining state” includes not only a state in which a part of the determination reference mark is removed but also a case in which the whole is removed.

  Here, in addition to the case where the plate-like member and the cell film are misaligned at the time of sticking by the sticking means, the defective product may also be caused by processing failure of the plate-like member, expansion or deformation of the plate-like member, etc. . According to the game board manufacturing facility of the present invention, regardless of any of these causes, in the defective product, the remaining state of the determination reference mark after cutting the determination opening is different from the non-defective product. Therefore, according to the game board manufacturing equipment of the present invention, not only when there is a problem in the cell film application process, but also when the processing failure or deformation of the plate-like member occurs in the process before the application process In addition, it is possible to execute a determination for accurately removing the defective product.

  Therefore, in the present invention, when the determination means determines that the product is defective, the defective product may be removed so as not to be sent to the next process. In this case, it is possible to notify the operator of the result of the pass / fail judgment using a “notification unit” such as a lamp or a buzzer, or to provide a marking unit for giving a mark to the defective product. Furthermore, the distribution means that distributes whether or not to transport the plate-like member to which the cell film is attached to the subsequent process based on the result of the quality determination by the determination means. ”Can automatically eliminate defective products. As a result, it is possible to accurately prevent a defective product from being transported to a subsequent process (eg, nailing or component mounting), causing waste of components or work, or shipping a defective product by mistake. .

  The opening for determination is recognized as an image of a color corresponding to the transparent portion after the cell film is cut and removed. In the present invention, since the configuration of “printing the determination reference mark with non-transparent ink” is adopted, if the configuration is such that all of the determination reference mark is removed from a non-defective product, the portion recognized as the determination opening The portion of the color used for the determination reference mark does not remain around. Further, if the non-defective product has a configuration in which a part of the determination reference mark is removed, the determination opening has a part of the color of the determination reference mark remaining in a predetermined shape around it. In this way, by adopting a configuration in which the determination reference mark is printed with a non-transparent ink having a color that can be distinguished from the design of the cell film, the determination opening can be cut and the quality determination can be accurately performed. .

  Furthermore, in this invention, a cell film is affixed from the back surface side of a plate-shaped member, and an imaging means performs an imaging from the surface side of a plate-shaped member. Therefore, in the image picked up by the image pickup means from the surface side of the plate-like member, the image based on the design of the cell film does not appear inside the determination opening. Such a configuration is also advantageous in accurately executing the above determination. Note that the surface of the plate-like member means a surface that becomes a front surface when an obstacle nail or the like is attached and assembled to the machine frame.

Here, the game board manufacturing facility of the present invention may further include the following configuration.
(2) The determination reference mark has the same shape as the shape of the determination opening, and there is a design expressed as a non-transparent region around the determination reference mark. Means for positioning the plate-like member so as to remove all of the determination reference mark by cutting the determination opening when the cell film is correctly attached to the plate-like member. Be configured as.

  In this case, it is possible to prevent a part of the determination reference mark from remaining on the non-defective product, and the further effect that the design property of the cell film is not impaired is exhibited.

In addition, the game board manufacturing facility of the present invention may further include the following configuration.
(3) The printing position of the determination reference mark is set so that the determination opening portion also serves as a boss hole of a part to be assembled to the plate-like member.

  Rather than cutting the judgment opening just for pass / fail judgment, it also serves as a boss hole, thereby reducing the number of man-hours and without increasing the number of holes opened in the plate-like member. This is because the portion does not adversely affect the strength of the plate-like member.

In addition, the game board manufacturing facility of the present invention may further include the following configuration.
(4) A printing position of the determination reference mark is set so that the plate-like member is provided with a component mounting means for mounting a component from the surface side, and is covered by the component mounted by the component mounting means. That.

  Covering the judgment reference mark with a part attached from the surface side of the plate-like member may impair the design of the cell film even if the judgment opening that completely removes the judgment reference mark is not formed. Because there is no. Examples of such parts include rail members and corner decorations that divide the periphery of the game area. Further, in this case, by adopting together with the configuration of (3), there is no waste if the boss hole for attaching these components is used as the determination opening.

In addition, the game board manufacturing facility of the present invention may further include the following configuration.
(5A) In the cell film, a plurality of the determination reference marks exist in at least two quadrants of the first quadrant to the fourth quadrant when divided by two straight lines orthogonal to each other at the center of the cell film. A number of criteria marks are printed.
(5B) The cutting means is configured to cut the determination opening with respect to each of the plurality of determination reference marks, and the determination means includes each of the plurality of determination reference marks. It is comprised as a means to perform the said quality determination based on a residual state.

  This is because, for example, the quality determination accuracy can be improved as compared with the case where only one determination reference mark is used. In this case, in particular, if the configuration of “(5C) the determination reference mark is provided outside the game area so as to be the diagonal position of the plate-like member” is adopted, the accuracy of pass / fail determination is further improved. Can be made. Further, in such a configuration, if the determination opening is also used as a boss hole of a part to be attached from the surface side of the plate-like member such as a rail member or a corner decoration, there is no waste, and the design is not impaired. It becomes possible to execute the pass / fail judgment with high accuracy.

  In the game board manufacturing facility of the present invention, the determination reference mark and the determination opening may be located inside the game area, for example, at a position corresponding to an opening for attaching an accessory such as a winning device.

  According to the present invention, it is possible to prevent defective products from being shipped by mistake when manufacturing a game board.

The second start winning device 27 includes an electric tulip that is opened and closed based on a normal symbol lottery result that is executed when a game ball passes through the gate 37.

  As described above, according to the present embodiment, the pass / fail determination station ST4 is provided after the cell pasting station ST2 and the drilling / cutting station ST3, and an image of the vicinity of the printing region of the determination reference marks MK1 and MK2 is taken. Because of the configuration that determines whether the product is non-defective or defective, it is not only due to misalignment when the cell film is applied, but also due to processing defects in the drilling / cutting process, and causes such as expansion and deformation of the acrylic resin plate itself. Good products can be removed accurately.

  This is removed in the non-transparent area near the corners of the second quadrant and the fourth quadrant of the cell film 2 "when the boss hole is processed on the assumption that the cell film is correctly attached to the plate member. If the determination reference marks MK2 and MK4 "are printed in black different from the surrounding colors, a black portion is formed around the image corresponding to the boss holes H2 and H4 found in the image of the corresponding part if it is a non-defective product. This is realized by adopting a configuration that does not remain.

  In addition, this pass / fail judgment is not performed when the cell film is applied, but is performed after the processing by the punching / cutting station ST3 is completed, so that not only the cause of cell film application failure but also the expansion of the acrylic resin plate is performed. It is also possible to discover the occurrence of defective products due to or deformation, as well as defective positioning at a cutting station or missing blades.

  Moreover, since the cell film 2 is affixed from the back surface side of the transparent acrylic resin board | plate material 1, and the structure which performs imaging from the surface side of the board | plate material 1 with the camera M42a is employ | adopted, in the imaged image, opening for determination The image based on the design of the cell film 2 is not reflected inside the boss holes H2 and H4 which are the portions. As a result, the above-described determination can be performed with high accuracy.

  Further, in the non-defective product, the determination reference marks MK1 and MK2 are completely removed by processing the boss holes H2 and H4, and the corner decorations 52 and 54 are attached using these boss holes H2 and H4. The provision of the determination reference marks MK1 and MK2 does not impair the design of the game board C. In addition, it is possible to reduce the number of man-hours and increase the number of holes opened in the plate member 1 by serving as the boss holes H2 and H4 instead of cutting the determination opening only for the quality determination. In addition, the strength of the plate 1 is not adversely affected.

  Furthermore, the determination reference marks MK2 and MK4 are printed in the second quadrant and the fourth quadrant when divided by two straight lines orthogonal to each other at the center of the cell film 2, and the determination device M43 displays the image PICa in the second quadrant corner. In addition, when one of the images PICb in the fourth quadrant corner portion is “NG”, it is determined as “defective product”, and thus the quality determination accuracy can be improved.

  Further, since the quality determination station ST4 includes the sorting device M44, defective products can be automatically removed. In addition, it not only automatically removes, but also contributes to the appropriate inspection opportunity of facilities by notifying the occurrence of defective products with warning lights and buzzers.

  Thus, according to the present embodiment, it is possible to prevent a defective product from being accidentally shipped when a game board is manufactured.

  The embodiment as the best mode for carrying out the invention has been described above. However, the present invention is not limited to this, and various modifications can be made without departing from the scope of the invention.

  For example, there may be only one determination reference mark, or conversely, three or more determination marks may be provided. If fiducial marks are provided at the four corners, the reliability of the pass / fail judgment is further improved. In addition, a determination opening dedicated to pass / fail determination may be cut separately from the component mounting boss hole, and a determination reference mark may be printed at the cutting position of the determination opening.

  In addition, for example, the determination reference mark is printed with a black circle having a diameter larger than that of the boss hole and the center of the boss hole is detected. May be. In this case, the pass / fail determination may be performed based on whether or not a black-shaped outline having a constant ring thickness exists around the boss hole as the outline of the black circle. On the contrary, it is also possible to use, for example, a judgment reference mark such that a crescent-shaped black portion remains in a non-defective product by using a judgment reference mark whose center does not coincide with the boss hole. In this case, a part of the design (for example, a part of a character's eyes, a part of a nostril, etc.) can be adopted as the determination reference mark instead of the dedicated determination reference mark “black circle”.

  Even if these black reference marks remain such that they are covered with a corner decoration or the like attached to the surface side, the design of the game board is not adversely affected.

  In addition, although the sorting apparatus M44 is installed in the embodiment, it is effective to give the operator an opportunity to remove defective products by a warning light or a notification by a buzzer.

  Further, the determination reference mark and the determination opening may be positioned inside the game area, for example, a position corresponding to an opening for attaching an accessory such as a winning device. Further, the positioning device is not limited to a fixed pin and a movable pin.

  The present invention can be used in a pachinko machine.
