Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a device for inserting a spring at the tip of a pachinko ball launching basket.
[0002]
[Prior art]
FIG. 4 is a first example of a conventional method. A hole 12 for standing the spring 11 is formed in the block 10, the spring 11 is inserted into the tapered tip pin 14 of the flange 13, and the end surface of the tapered tip pin 14 is stroked with a hammer or the like, or pressed with pressure. It was press-fitted.
5 and 6 show a second example of the conventional method. The tightly wound portion 15 of the spring 11 that was press-fitted into the tapered tip 14 of the heel 13 was fixed with pliers 16 and the end surface of the heel tip was pushed in with a hammering pressure.
[0003]
[Problems to be solved by the invention]
In the above prior art, the difference in the spring length after press-fitting, the difference in the winding end position of the contact surface of the pachinko ball of the spring, the bending of the spring, the difference in press-fitting and torsional distortion, etc. occur. Since it affects the variation of the ball jump, there is a problem that a large variation of the ball jump occurs due to the kite.
[0004]
[Means for Solving the Problems]
An object of the present invention is to solve the above-mentioned problems, and is a device for inserting a spring into the tip pin of a pachinko ball launcher . The spring holder set on the rotating and moving working shaft has a spring winding end position. Alignment marks are provided, and a hole for screwing the spring is formed. The spring is held so that it touches the bottom. The spring is held on the same line as the center of the tip pin. Insert the spring holder linearly until it comes into contact with the inner diameter, then screw the spring holder into the amount of the wire diameter pitch of the spring and screw it in the specified amount by relative rotation. After the screwing is finished, move the tip pin and the spring holder relative to each other. It has a function of retracting by reverse rotation and extracting the spring holder from the spring fixed to the tip.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described in detail based on the illustrated examples.
FIG. 1 to FIG. 3 show an embodiment of the present invention in which a scissor set base for setting a fixed scissors and a spring holder rotate and move.
The spring holder 1 is set on an operating shaft that rotates and moves. The operating shaft controls the rotation angle, the number of rotations, and the amount of movement. The scissors set base is a head guide pin that uses the scissors rotation shaft hole as a guide so that the scissors are set so that the center of rotation of the spring holder 1 coincides with the center of the scissors pin, and the head portion behind the scissors pin It consists of a contact member.
[0006]
The operating shaft measures the rotation angle, movement amount, etc. of the shaft by a sensor, controls the drive source, and performs the setting operation. In automatic operation, set the kite on the kite set stand, set the spring 2 so that the spring winding end position is aligned with the mark on the spring holder 1, and start with the start SW.
The spring holder 1 advances to a straight movement position (a point where the inner diameter of the spring 2 and the outer diameter of the tip pin 3 substantially coincide) set in a state where the spring holder 1 does not rotate. From this point, the spring holder 1 is rotated relative to the spring 2 and screwed to the set end position by the amount of the wire diameter pitch of the spring 2. Then, push in the thickness of the spring material line. The set rotation amount around screwing process ends.
Next, the spring holder 1 is moved backward while being reversely rotated to remove the spring 2 from the spring holder 1 and return to the origin to complete the operation.
[0007]
In order to adjust the difference due to the variation between the lots of the kite, the hole guide pin that guides the shaft of the kite rotation shaft hole, the contact member of the head part on the rear side of the kite tip pin, the head of the kite is a spring holder A fine adjustment device is provided (not shown) so that the center of rotation of 1 and the center of the tip pin 3 coincide.
In the embodiment, the spring holder is rotationally moved, but since the relative relationship between the spring and the tip pin, the movement and rotation may be any combination, and in order to increase safety, a locking device that fixes the rod during operation, for example, It is even better to use a presser arm, an adsorption magnet (adsorbed at the start), vacuum adsorption, or the like.
[0008]
【The invention's effect】
In the present invention, when inserting a spring into the tip pin of a pachinko ball launcher, the spring is held on the spring holder so that it hits the bottom, the spring is held on the same line as the center of the tip pin, Insert the spring holder in a straight line until the outer diameter and the spring inner diameter come into contact with each other, and then screw the spring holder into the amount of the wire diameter pitch of the spring and screw it into the specified rotation amount by relative movement rotation. Since the holder has a function of retracting the holder by relative movement and reverse rotation and removing the spring holder from the spring fixed to the tip, the spring length after press-fitting, the winding end position of the contact surface of the spring pachinko ball, press-fitting and torsional distortion, etc. Has become uniform, and there is no spring bending or overturning, so that it is possible to stably supply a kite that does not fluctuate.
