Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a nail driving device for driving a nail into a game board such as a pachinko machine.

[0002]

2. Description of the Related Art A game board such as a pachinko machine is provided with a window hole into which a display digital device is fitted and stored, a prize ball hole, a ball discharge hole, and the like. A rail for guiding the hit ball is laid, and a part of the nail body supports the windmill.

Conventionally, in this surface treatment, first, a nail body is driven by a nailing machine according to a predetermined pattern in a predetermined order, and then the nail body having passed through the windmill is nailed in a predetermined pattern in a predetermined order. The procedure was such that a special machine was used, and finally a curved rail was driven.

The order of the nailing pattern or the above-mentioned procedure is constant. The reason for this is that nailing must be done with multiple nails in close proximity to a narrow area,
New casting had to be done while avoiding the existing nails.

[0005] Such complicated and inefficient procedure must be adopted because the conventional form of the nailing device drives the nail while holding the center of the axis of the nail body with the chuck device. . Here, when a new nail body is driven, the nail device is held in a predetermined pattern only from a certain direction so that the chuck device holding the nail body does not collide with the existing nail body.

[0006] In particular, it is extremely difficult to nail the rail after driving the rail, and it is also difficult to drive a new nail near the nail to which the windmill is mounted. It was.

However, in the process of manufacturing a large number of products, accidents such as mistakes in nailing or dropping of nails occur, and in such a case, the dedicated machine cannot be used for the above-mentioned reason. Therefore, it was manually added. For example, the invention "a nailing aid in a pachinko machine" disclosed in Japanese Patent Application Laid-Open No. 10-80533 is a kind of a jig used at the time of the manual operation as described above.

[0008]

Conventionally, the nail is driven from the center to the lower part of the shaft of the nail while being held by a chuck device. The goal was to make it possible to prevent the displacement by making it as close as possible to the driving target of the game board, but in addition, the chuck device also served as a stopper to control the driving depth of the nail body. It is.

The lengths of the nails are, of course, all constant. Therefore, if the installation depths of a large number of nails are different, the distance between the board surface of the game board and the head of the nails differs depending on the nails. Will do. Such a variation prevents a smooth flow of a hit ball, which is extremely inconvenient for a game board. Therefore, it is necessary to arrange the stopper in some form so that the nail body is not driven into the predetermined depth or more by the hammer.

FIG. 14 and FIG. 15 are schematic views showing a conventional nailing apparatus of this type, in which a window hole B is opened in a part of a game board A, and the vicinity of the window hole B in FIG. FIG. 15 shows a state immediately after the nail body C is driven and completed from the standby state in which the nail body C is aligned.

An axis E which is continuous with the head D of the nail C is held at its center by the chuck device 1, and the nail C is driven into the game board A by hitting the hammer 2 on the head D. .

However, since the stopper 3 is interposed between the chuck device 1 and the hammer 2, the hammer 2 descends simultaneously with the stopper 3, so that the stopper 3
In the state where the hammer 2 is stopped by contact with the nail member 2, the lowering of the hammer 2 is also stopped, so that the further driving of the nail C is stopped (see FIG. 15).

In such a form, the chuck device 1
In order to operate the chuck device 1 without being disturbed by the existing nail body, it is necessary to hold the center of the axis E of the nail body C or less corresponding to the driving depth of the nail body C. ,
It is inevitable that the procedure must be followed to avoid the existing nails.

In the conventional nailing for a windmill, a dedicated machine is used to first place the windmill at a predetermined position on the board surface with its chuck device, and insert the nail body into a hole in the center of the windmill to drive the nail body. Was. However, here, the nail body is not directly held by the chuck device, but is only held by the hole at the center of the windmill, so that the posture is unstable, and there has been a problem that the nail body is inclined at the time of driving.

Therefore, the present invention is a nail driving device developed to solve the above-mentioned drawbacks and disadvantages of the prior art, and is used for driving nails on a game board such as a pachinko machine, driving a windmill nail, The rails can be laid in any order in a random order, and it is easy to perform the additional casting of the places where the nails fall off. The purpose is to be able to achieve.
