Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) The invention efficiently inserts a fixing member for fixing the rail attached to the guide rail of the ball into a pilot hole provided in the game board. The present invention relates to a pre-treatment device for installing guide rails in pachinko machines.

(Prior art) Conventionally, in order to attach a guide rail to a game board, pilot holes are provided at appropriate intervals on the game board side in correspondence with the installation position of the guide rail, and the guide rail is inserted in a manner that corresponds to the position of the pilot hole. Temporarily attach multiple fixing members such as pins attached to the board by inserting them into prepared holes while bending the guide rail by hand, and then press-fit the pins into the game board using a press-fitting device to fix them. I found a way to do that.

(Problem to be solved by the invention) However, according to the above temporary mounting method, each pin is placed uniformly in each prepared hole due to the elastic force of the metal plate guide rail trying to return to a straight line. It is difficult to insert the pin in an upright position, and as a result, the pin may be tilted relative to the pilot hole and cannot be inserted completely. For this reason, incidental work such as hitting the upper edge of the guide rail with a hammer etc. is required to completely push the pin floating out of the pilot hole into the pilot hole, which does not improve work efficiency, and also makes it impossible to improve work efficiency. There was also a high possibility that the sagging guide rail would be deformed.

The present invention was developed in view of the above circumstances, and its purpose is to eliminate the need for extra work such as hitting with a hammer, etc., thereby increasing work efficiency and preventing damage to the guide rail. To provide a pre-treatment device for installing a guide rail in a pachinko machine that is free from the risk of damage.

[Structure of the invention] (Means for solving the problem) The guide rail installation pre-processing device for a pachinko machine according to the invention has a device that hangs on a predetermined position of the guide rail in order to erect and fix the guide rail on the board surface. A board installation member for setting a game board, which has a prepared hole on its surface for pushing in the fixed fixing member, and a gripping mechanism that is openable and closable to grasp the guide rail together with the fixing member at a position symmetrical to the prepared hole. and a rail installation member provided with a guide member that guides the guide rail in a curved manner between the gripping functions, and the panel installation member and the rail installation member are brought close to each other at a predetermined opposing interval and fixed. It is characterized by having a structure in which the member is inserted into a prepared hole.

(Function) Set the game board on the board installation member. On the other hand, the fixing member attachment portion of the guide rail is inserted and gripped between the gripping members of each gripping function of the rail installation member while using the guide member. Next, by moving the board installation member or the rail installation member, each fixed member is inserted into each pilot hole provided in the game board in a plane symmetrical relationship with respect to these fixed members. The fixing member mounting portions of the guide rail are gripped by respective gripping mechanisms, and the fixing members are restrained so as to be approximately perpendicular to the game board, so the fixing members cannot be completely inserted straight into the prepared holes. ,
The post-processing press-fitting process becomes easier.

(Example) An example of the present invention will be described below with reference to the drawings.

In Figure 1, which shows the overall configuration of the device, 1 is the base of the device, which consists of pillars 3 of the same height set up at the four corners of a square plate-shaped bottom plate 2, with the top end of each of them erected by a rod. It is constructed by being fixed to each of the four corners of the top frame 4 which forms a frame shape. A bearing member 5 is attached to the upper surface of each central portion of the two opposing sides of the top frame 4. Reference numeral 6 denotes a square board-shaped stand serving as a board installation member on which the game board 7 of the pachinko machine is set, and supports 3 are inserted into holes 6a provided at the four corners of the stand.
It is supported so that it can be moved up and down in a horizontal state by inserting it through it.

Reference numeral 9 denotes a rail installation board as a rail installation member for setting the metal plate guide rail 10 of the pachinko machine, and has a rectangular shape with dimensions that allow it to fit comfortably inside the top frame 4. At the center of each of the two sides, a pair of leg members 11 is attached so as to face the bearing member 5 provided on the top frame 4. By supporting both ends of the rotating shaft 12 fitted to these leg members 11 on the bearing members 5, the rail installation board 9 can be rotated 180° around the rotating shaft 12 and turned upside down. Note that the rail installation board 9 is turned upside down by a drive device (not shown).

Next, in FIGS. 1 to 4, reference numeral 13 denotes a gripping mechanism for the guide rail 10 and a pin 14 which is a fixing member for attaching the guide rail, and as shown in FIG. Pin 1 provided
A plurality of them are attached to the rail installation board 9 with a plane symmetrical positional relationship with respect to the pilot hole 15 for insertion of No. 4. As shown in FIG. 3, this gripping mechanism 13 includes a U-shaped frame member 16, a pair of gripping members 18 that are incorporated inside the U-shaped frame member 16 and rotate like scissors around a support shaft 17, and A compression spring 19 that biases the member 18 in the opening direction, and this spring 19
The wedge 20 is pushed into the opposing gap on the proximal end side of the pair of gripping members 18 in order to close the pair of gripping members 18 against the elastic force of the wedge 20, and a cylinder 21 for vertically moving the wedge 20. ing.
Reference numeral 22 denotes a small groove formed on each gripping surface of the pair of gripping members 18 for holding the pin 14 in an upright state with respect to the guide rail 10. This pin 14
As shown in FIG. 2, the pin is made of a split pin made by folding a metal wire in half, and is attached by being inserted into a pin insertion hole 10a provided in the guide rail 10.

Further, in FIG. 2, reference numerals 23 and 24 are guide rails which are respectively guide members attached to the rail installation board 9, and each of the two guide rails 10, 10 to be attached to the game board 7 is guided by each gripping mechanism 13. This facilitates the work of sequentially inserting the gripping members 18 between the pair of gripping members 18.
A pair of arcuate members 25 and 26 are laid in parallel between each other with a gap approximately equal to the plate thickness of the guide rail 10.

Next, the operation of the above configuration will be explained. First, the cylinder 8 is operated to lower the table 6, and the game board 7, on which the pilot hole 15 has been previously formed, is placed on top of the table 6, thereby setting the game board 7 in a fixed position as shown in FIG. . On the other hand, the rail installation board 9 is rotated around the rotating shaft 12 by a drive device (not shown),
The gripping mechanism 13 is fixed in such a manner that the gripping member 18 of the gripping mechanism 13 faces upward as shown in FIG. Thereafter, as shown in FIG. 2, the guide rail 10, on which the pin 14 has been previously attached, is placed so that the side where the pin 14 is attached faces upward, and its tip is placed in an arc shape on the rail installation board 9. It is inserted between a pair of gripping members 18 located at the end of the group of gripping mechanisms 13 that are scattered, or into the end of the guide rail 23. At this time, since the cylinder 21 of each gripping mechanism 13 is retracted, the pair of gripping members 18 are in an open state as shown by the two-dot chain line in FIG. Next, when the guide rail 10 is pushed in the direction of the arrow in FIG. The gripping mechanism 1 is pushed in or guided by the guide rail 24.
It is inserted between a pair of gripping members 18 of No. 3. Then, by continuing to press the guide rail 1
0 passes between the pair of gripping members 18 of the gripping mechanism 13 one after another while being guided in a curved manner by the guide rails 23 and 24. After inserting the guide rail 10 between each pair of gripping members 18 in this way,
The position of the guide rail 10 is adjusted so that the mounting portion of each pin 14 is located between each pair of gripping members 18 and the pin 14 faces the small groove 22. Therefore,
When the cylinder 21 is moved forward, each pair of gripping members 18 will be in the closed state shown in solid lines in FIG. 3 while allowing each pin 14 to be pushed into each small groove 22. is firmly gripped by each gripping mechanism 13 with each pin standing vertically. Thereafter, the rail installation board 9 is rotated 180 degrees around the rotating shaft 12, brought to a downward position as shown in FIG. 4, and fixed in this position. Next, when the cylinder 8 is moved forward, the game board 7 rises together with the stand 6, and each of the pilot holes 15 provided on the board surface is connected to each pin 14, which is fixed to the rail installation board 9 and is located opposite to the pilot hole 15. Insert it into the tip. And each pin 14
When the guide rails 10 and pins 14 are completely inserted into the respective prepared holes 15, the advance movement of the cylinders 8 is stopped, and the guide rails 10 and the pins 14 are released from the grips of the respective gripping mechanisms 13.
The pre-installation process for 0 is completed. The game board 7 that has undergone the pre-installation process for the guide rail 10 is taken out by moving the cylinder 8 backward to return the table 6 to the lowered position, and then the pin 14 is inserted by a press-fitting device (not shown).
is pushed into the game board 7 to fix the guide rail 10.

In this way, the pin mounting portion of the guide rail 10 is held by the gripping mechanism 13, that is, the pin 14 is held substantially perpendicular to the game board 7 and inserted into the prepared hole 15, so that the pin 14 is inserted into the prepared hole 15. Pilot hole 1
5, it is completely inserted straight without tilting. Therefore, there is no need for the unnecessary work of hitting the guide rail 10 and completely inserting the pin 14 into the prepared hole 15 later, and the guide rail 10 is not deformed. Further, since a large number of pins 14 can be inserted into the prepared holes 15 at once, pre-treatment for installing the guide rail 10 can be completed in a short time.

Furthermore, as in this embodiment, the guide rails 23, 24
By providing this, it is possible to efficiently insert the linear guide rail 10 between the pair of gripping members 18 of each gripping mechanism 13 while bending it.

In the above embodiment, the guide rails 23 and 24 are constructed of a pair of arcuate members 25 and 26, but the inner arcuate member 25 may be omitted. Furthermore, the guiding member can also consist of a guide roller. Alternatively, the mounting base 6 may be fixed and the rail installation board 9 may be moved up and down, or the support structure of the rail installation board 9 and the configuration of the gripping mechanism 13 may be changed as necessary. It's okay.

[Effect of the invention] As is clear from the above explanation, according to the invention, each fixing member attached to the guide rail can be inserted into each pilot hole of the game board at once, and moreover, at the time of insertion, Since the fixing member is held substantially perpendicular to the game board, the fixing member can be completely inserted into the prepared hole. Therefore, the guide rail can be attached to the game board extremely efficiently, and there is no need to hit the guide rail with a hammer or the like as in the conventional case, and there is no inconvenience that the guide rail may be damaged.

Further, by providing the guiding member between the gripping mechanisms, it is possible to efficiently perform the process of bending the guide rail into an arc shape and gripping the guide rail between the gripping mechanisms.
