Description

  The present invention relates to an attachment method and attachment jig for attaching a launch rail to a game board of a ball game machine.

  A launch rail for guiding the launch of the game ball is attached to the game board of the ball game machine. This type of launch rail is formed by protruding a plurality of retaining pins on a rail made of elastically deformable plate material (for example, a straight stainless steel plate), and when manually attaching to a game board The stop pin is driven into the board surface of the game board while curving the rail portion according to the shape of the mounted state.

In addition, since the mounting position and the bending state of the launch rail affect the launch direction and launch speed of the game ball, high-precision positioning is required when the launch rail is attached to the game board. Therefore, conventionally, a punch hole or the like is formed in advance at the stop pin driving position of the game board to facilitate positioning of the firing rail.
Japanese Patent Laid-Open No. 10-15163

However, since the launch rail is relatively high in rigidity, it is not easy to position the stop pin in the punch hole or the like while holding the curve, which is a laborious and time-consuming operation.
In addition, when the launch rail is manually attached, there is a problem that the amount of the stop pin driven into the game board is likely to vary. In particular, when the stop pin is excessively driven, an excessive load is applied to the stop pin and the rail portion, and the stop pin may be bent or the rail portion may be deformed.

The present invention is a launch rail mounting method created for the purpose of solving these problems in view of the above circumstances, and a plurality of set pins are provided in a protruding manner on a rail portion made of an elastically deformable plate material. The firing rail formed in this way is curved in accordance with the shape of the mounting state, and when the stop pin is driven into the board surface of the game board, the firing rail is held in the curved shape of the mounting state, and the curved shape is Using a mounting jig capable of positioning the held firing rail at the launch rail mounting position of the game board, and driving and holding the firing rail with the mounting jig, the stop pin is driven into the board surface of the game board. It is characterized by.
At this time, before the mounting jig is positioned on the board surface of the game board, the firing rail can be set on the mounting jig.
The firing rail may be set on the mounting jig after the mounting jig is positioned on the board surface of the game board.
In this way, even if the launch rail is attached manually, it becomes easier to hold and position the launch rail, so that not only can the labor of the operator be reduced, but also the accuracy of the launch rail is improved. Can be improved.
In addition, the present invention provides a game board in which a firing rail formed by projecting a plurality of stop pins on a rail portion made of an elastically deformable plate material is bent in accordance with the shape of the mounted state. A mounting jig used when driving into the board surface of the game board, and a curved holding portion that holds the firing rail in a curved shape in the attached state, and the firing rail that is held in the curved shape is mounted on the launch rail on the game board And a positioning portion for positioning.
With this configuration, the mounting rail can be held and positioned with a mounting jig, so not only can the labor of the operator be reduced when mounting the rail manually, but also the mounting accuracy of the rail is improved. Can be improved.
Further, the curved holding portion has a cross-sectional shape, and the firing rail is curved and held by a holding groove formed inside thereof. If comprised in this way, not only can a firing rail bend | curved reliably, but a mounting jig can be easily removed after a firing rail attachment.
In addition, a notch portion for hitting the upper portion of the firing rail with a tool when the stop pin is driven into the board surface of the game board is formed in the upper portion of the curved holding portion. If comprised in this way, the upper part of a firing rail can be hit with a tool, without being disturbed by an attachment jig. Further, if the notch is formed only at the position of the stop pin, the position where the tool is struck becomes clear, so that the efficiency of the rail mounting operation can be increased.
Further, the curved holding part is characterized in that a height at the notch part substantially coincides with a height of the firing rail. If comprised in this way, since it can restrict | limit the driving amount of the stop pin with respect to a game board with an attachment jig, it can prevent the bending of the stop pin by excessive driving | operation, and a deformation | transformation of a rail part.
In addition, a second cutout portion for avoiding interference with the stop pin is formed at a lower portion of the curved holding portion. If comprised in this way, the fall of workability | operativity by interference of a stop pin and an attachment jig | tool can be avoided. Further, since the stop pin can be visually confirmed through the second notch portion, there is an advantage that it is easy to check the drive position and the drive amount of the stop pin.

  According to the present invention as described above, when attaching the launch rail to the game board manually, it is not necessary to hold the launch rail curved by hand, so that the labor of the operator can be greatly reduced. In addition, since it becomes possible to accurately position the firing rail with respect to the game board, the mounting accuracy of the firing rail can be improved.

Next, embodiments of the present invention will be described with reference to the drawings.
[Game board and launch rail]
In FIG. 1, reference numeral 1 denotes a game board of a pachinko machine. The game board 1 includes an outer launch rail 2, an inner launch rail 3, a game nail 4, a windmill 5, a center accessory 6, a start port 7, a large A winning port 8, a winning port 9, a gate 10, and the like are attached. The present invention is suitable for the case where the launch rails 2 and 3 are manually attached to the game board 1. Hereinafter, the outer firing rail 2 will be described as an example.

  As shown in FIG. 2, the firing rail 2 includes a rail portion 2 a made of an elastically deformable plate material, and a plurality of stop pins 2 b that protrude from the lower end portion of the rail portion 2 a at a predetermined interval. Is formed. As a plate material forming the rail portion 2a, a stainless steel plate having relatively high rigidity is used. Although the rail portion 2a is bent at one end portion, the rail portion 2a is linear as a whole before being attached, and needs to be bent in accordance with the shape of the attached state at the time of attachment.

  The fixing pin 2b is of a split pin type in which the base end portion is broken, and is welded to the rail portion 2a in a state where the broken portion sandwiches the lower end portion of the rail portion 2a. When attaching the firing rail 2 to the game board 1, the stop pin 2 b is driven into the game board 1. This driving is performed by hitting the upper portion of the rail portion 2a with a tool such as a hammer. Since a high accuracy is required for the driving position of the locking pin 2b, a plurality of pin insertion holes 1a such as punch holes are processed in advance at the locking pin driving position of the game board 1. After inserting the tip of the stop pin 2b into these pin insertion holes 1a, the stop pin 2b is driven by a tool.

[First embodiment]
In FIG. 3, reference numeral 11 denotes an attachment jig used when attaching the launch rail 2 to the game board 1, and the attachment jig 11 is a curved holding portion 11 a that holds the launch rail 2 in a curved shape in the attached state. And a positioning portion 11b for positioning the launch rail 2 held in a curved shape at the launch rail mounting position of the game board 1.

  The curved holding portion 11a is formed by, for example, bending a plate material that is difficult to be elastically deformed into a cross-sectional shape and bending the plate material in accordance with the mounting shape of the firing rail 2. If comprised in this way, the curved holding groove 11c opened downward will be formed inside the curved holding part 11a, and the rail part 2a of the firing rail 2 can be curvedly held by this holding groove 11c.

  A plurality of first notches 11d for hitting the upper part of the firing rail 2 with a tool when the stop pin 2b is driven into the board surface of the game board 1 are formed at the upper part of the curved holding part 11a. If such a first notch portion 11d is formed, the upper portion of the firing rail 2 can be hit with a tool without being obstructed by the mounting jig 11. In addition, since the first notch portion 11d of the present embodiment is formed only at the position corresponding to the stop pin, there is an advantage that the position of hitting with a tool becomes clear.

  Further, in the present embodiment, as shown in FIG. 4, the height H1 of the curved holding portion 11a in the first notch portion 11d is made to coincide with the rail height H2 of the firing rail 2. As a result, the mounting amount of the stop pin 2b with respect to the game board 1 is limited by the mounting jig 11, and it is possible to prevent the stop pin 2b from being bent and the rail portion 2a from being deformed due to excessive driving.

  Furthermore, a plurality of second cutout portions 11e for avoiding interference with the stop pin 2b are formed in the lower portion of the curved holding portion 11a. That is, since the base end portion of the stop pin 2b slightly protrudes from the front and back of the rail portion 2a, there is a possibility of interfering with the mounting jig 11 and hindering the rail mounting operation. According to the notch portion 11e, not only can the interference between the stop pin 2b and the mounting jig 11 be avoided, but also the stop pin 2b can be visually observed through the second notch portion 11e, so And confirmation of the driving amount can be facilitated.

  In addition, although the curve holding | maintenance part 11a of this embodiment does not position the position of the firing rail 2 in the length direction correctly, you may make it position in the length direction. For example, if a stopper portion is formed in the holding groove 11c by a pin or a cut and raised, and one end portion in the length direction of the rail portion 2a is brought into contact with the stopper portion, the positioning of the firing rail 2 in the length direction is performed. It can be carried out. However, when the dimensional accuracy of the firing rail 2 is not so good, the position in the length direction may be finely adjusted at the time of attachment, so that the positioning in the length direction is performed like the curved holding portion 11a of the present embodiment. There may be times when it is not.

  The positioning part 11b of the present embodiment is formed so as to protrude from both ends of the curved holding part 11a. Each positioning portion 11b is provided with a positioning pin 11f that protrudes downward. By inserting these positioning pins 11f into positioning holes 1b that are formed in advance on the surface of the game board 1, the mounting jig 11 is inserted. Alternatively, the firing rail 2 held by the mounting jig 11 is positioned with respect to the game board 1. The formation position, shape, and number of the positioning portions 11b can be changed as appropriate. However, if the positioning portions 11b are provided at both ends of the mounting jig 11 as in the present embodiment, the game board 1 and the mounting jig 11 The backlash in the meantime can be minimized.

  Next, a method for mounting the firing rail 2 using the mounting jig 11 will be described with reference to FIGS. 5 and 6. The launch rail 2 is attached to the game board 1 after, for example, the game nail 4 and the windmill 5 are attached and before the corner decoration (not shown) is attached. As a method for attaching the firing rail 2, a method in which the firing rail 2 is manually attached to the game board 1 in a temporarily fixed state and then the firing rail 2 is press-fitted into the game board 1 with a rail press-fitting machine (not shown). In addition, there is a method of attaching the launch rail 2 to the game board 1 only by manual work, but in any case, the attachment method of the present invention can be applied.

  In this embodiment, first, as shown in FIG. 5, the firing rail 2 is set on the mounting jig 11. This operation is performed by inserting the rail portion 2 a of the firing rail 2 into the holding groove 11 c of the mounting jig 11. When the rail portion 2a is inserted into the holding groove 11c, the rail portion 2a is bent along the curved holding portion 11a and held in a curved shape.

  Next, the mounting jig 11 on which the firing rail 2 is set is positioned on the game board 1. This operation is completed simply by inserting the positioning pin 11f provided in the positioning portion 11b of the mounting jig 11 into the positioning hole 1b formed in advance on the board surface of the game board 1. When positioning is performed in this manner, the position of the stop pin 2b provided on the firing rail 2 and the position of the pin insertion hole 1a formed in advance on the game board 1 substantially coincide. However, when there is a gap between the two, the firing rail 2 can be slid in the length direction to finely adjust the position of both.

  Next, the upper part of the firing rail 2 is hit with a tool, and the stop pin 2 b is driven into the game board 1. This operation is performed through a first notch portion 11d formed on the upper portion of the curved holding portion 11a. When the firing rail 2 is attached in a temporary stop shape and then press-fitted with a press-fitting machine, the amount of driving of the stop pin 2b is conservative, and when the firing rail 2 is attached only by hand, the lower end of the rail portion 2a is the game board The stop pin 2b is driven until it hits the board surface of 1. At this time, since the height H1 of the curved holding portion 11a in the first notch portion 11d coincides with the rail height H2 of the firing rail 2, the amount of driving of the stop pin 2b with respect to the game board 1 is determined by the mounting jig 11. To prevent excessive driving.

  Next, the attachment jig 11 is removed. This operation only lifts the mounting jig 11 upward. When the launch rail 2 is attached only by manual work, the attachment work is completed. Moreover, when the firing rail 2 is temporarily fixed, the press-fitting process by a press-fitting machine is performed and the attachment of the firing rail 2 is completed.

  According to the embodiment of the present invention configured as described above, the firing rail 2 formed by projecting a plurality of stop pins 2b on the rail portion 2a made of an elastically deformable plate material is shaped into an attached state. When the stop pin 2b is driven into the board surface of the game board 1 while being bent together, the launch rail 2 is held in a curved shape in the attached state, and the launch rail 2 held in the curved shape is attached to the launch rail of the game board 1 Since the mounting jig 11 that can be positioned is used and the firing rail 2 is positioned and held by the mounting jig 11, the stop pin 2 b is driven into the board surface of the game board 1. Even when it is attached, the firing rail 2 can be easily held and positioned. Thereby, not only can an operator's labor be reduced, but also the mounting accuracy of the firing rail 2 can be improved.

  Further, the curved holding portion 11a of the mounting jig 11 has a cross-sectional shape and is formed so as to hold the firing rail 2 in a curved manner by the holding groove 11c formed inside thereof, so that the firing rail 2 can be securely attached. In addition to holding the curve, the mounting jig 11 can be easily removed after the firing rail 2 is mounted.

  In addition, when the stop pin 2b is driven into the board surface of the game board 1, a first notch part 11d for hitting the upper part of the firing rail 2 with a tool is formed on the upper part of the curved holding part 11a. The upper part of the firing rail 2 can be hit with a tool without being disturbed by the jig 11. Moreover, in this embodiment, since the 1st notch part 11d is formed only in the corresponding | compatible position of the stop pin 2b, the position where it hits with a tool becomes clear and the efficiency of a rail attachment operation | work can be improved.

  Further, since the height H1 at the first notch portion 11d is substantially equal to the height of the firing rail 2, the bending holding portion 11a has the mounting jig 11 to set the amount of the stop pin 2b to be driven into the game board 1. Can be limited. As a result, it is possible to prevent breakage of the stop pin and deformation of the rail portion due to excessive driving.

  Moreover, since the 2nd notch part 11e for avoiding interference with the stop pin 2b is formed in the lower part of the curve holding | maintenance part 11a, the fall of workability | operativity by interference with the stop pin 2b and the attachment jig | tool 11 is avoided. it can. Moreover, since the stop pin 2b can be visually observed through the second notch portion 11e, it is easy to check the drive position and the drive amount of the stop pin 2b.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. However, about the structure which is common in 1st embodiment, the same code | symbol as 1st embodiment is attached | subjected and description of 1st embodiment is used.

  As shown in FIG. 7, the mounting jig 11B of the second embodiment does not include the holding groove 11c in the curved holding portion 11a, and holds the firing rail 2 in a curved manner on the side surface (inner peripheral side) of the curved holding portion 11a. This is different from the first embodiment. In order to hold the firing rail 2 in a curved manner on the side surface of the curved holding portion 11a, it is considered necessary to lock both ends in the length direction of the firing rail 2, but the firing rail 2 of the present embodiment is not less than a semicircle. In order to form the circular arc, it remains on the inner surface of the curved holding portion 11a by its own elastic restoring force, and is curved and held by the mounting jig 11B.

  Next, a method for mounting the firing rail 2 using the mounting jig 11B of the second embodiment will be described with reference to FIG. As shown in these drawings, in the second embodiment, first, the mounting jig 11B is positioned on the game board 1. This operation is completed simply by inserting the positioning pin 11f provided in the positioning portion 11b of the mounting jig 11B into the positioning hole 1b formed in advance on the board surface of the game board 1.

  Next, the firing rail 2 is set on the mounting jig 11B positioned on the game board 1. This operation is performed by placing the rail portion 2a of the firing rail 2 along the inner peripheral curved surface of the curved holding portion 11a. If it does in this way, the position of the stop pin 2b provided in the launch rail 2 and the position of the pin insertion hole 1a previously formed in the game board 1 will correspond substantially. However, when there is a gap between the two, the firing rail 2 can be slid in the length direction to finely adjust the position of both.

  Next, the upper part of the firing rail 2 is hit with a tool, and the stop pin 2 b is driven into the game board 1. This operation is performed through a first notch portion 11d formed on the upper portion of the curved holding portion 11a. When the firing rail 2 is attached in a temporary stop shape and then press-fitted with a press-fitting machine, the amount of the stop pin 2b is conservative, and when the firing rail 2 is attached only by hand, the lower end of the rail portion 2a is the game board. The stop pin 2b is driven until it hits the board surface of 1.

  Next, the attachment jig 11B is removed. This operation only lifts the mounting jig 11B upward. When the launch rail 2 is attached only by manual work, the attachment work is completed. Moreover, when the firing rail 2 is temporarily fixed, the press-fitting process by a press-fitting machine is performed and the attachment of the firing rail 2 is completed.

  Needless to say, the present invention is not limited to the above embodiment. For example, the mounting jig may be configured so that the outer firing rail and the inner firing rail can be curved and held simultaneously. In this case, the outer firing rail and the inner firing rail can be attached together.
