Description

Detailed Description of the Invention Object of the Invention (Field of Industrial Application) The present invention relates to a rotor assembly in which a lock plate and a coil spring are inserted into a rotor disposed in a key cylinder such as an ignition key or a door key of a vehicle. This is related to the attached machine.

(Prior art) Conventionally, as a type of rotor assembly machine, the rotor is supported horizontally, and in that state, a coil spring is first inserted into a lock plate hole that opens upward, and then a lock plate is inserted into the lock plate hole. It is inserted. After the insertion operation, the missing item detection device detects whether the coil spring and the lock plate have been inserted into the lock plate hole. That is, the missing item detection device detects missing items of the lock plate and coil spring by bringing a detection pin into contact with the lock plate whose tip protrudes from the outer peripheral surface of the rotor due to the biasing force of the coil spring from the direction in which the lock plate is inserted. It's becoming like that.

(Problem to be solved by the invention) In recent years, plural rotors have been put into practical use, in which lock plate holes are opened on both sides of the rotor axis, and coil springs and lock plates are inserted from both sides of the rotor. Hold the rotor vertically for rotors like
A new assembly machine has been proposed in which the coil spring and the lock plate are inserted into the lock plate hole which opens laterally using a push arrow in this state. However, in such an assembling machine, there is a push arrow in the lock plate insertion direction, so there is a problem that the conventional missing part detection device as described above cannot be used.

Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention supports a rotor vertically, and horizontally inserts a coil spring and a lock plate into a lock plate hole formed in the rotor. In a rotor assembly machine that inserts a rotor with a push arrow, one end of the lock plate can be moved in and out of the rotor by moving the push arrow in and out of the rotor, and a contact detector is provided at the position where the lock plate comes in and out.

(Function) With the above means, when one end of the lock plate protruding from the rotor comes into contact with the contact detector when the push arrow is inserted into the rotor, the presence of the lock plate is confirmed, and when the push arrow is pulled, the biasing force of the coil spring When the lock plate sinks into the rotor, the presence of the coil spring is confirmed because the lock plate does not come into contact with the contact detector.

are reliably separated, and the transfer jig 19 is inserted into each insertion hole 21.
The coil springs 4 are rotated downward in a state in which one coil spring 4 is housed in each.

After the rotating arm 20 is rotated to the vertical direction, the third
As shown in the figure, the transfer jig 19 moves forward until it is positioned on both sides of the rotor jig 7 at the assembly position P. At this time, the second and third locking pins 2 in the transfer jig 19
8 and 29 are recessed from each insertion hole 21, and each insertion hole 21
are in communication with each groove 15 of the elevator 9 and the insertion hole 17 of the rotor jig 7.

When the transfer jig 19 reaches both sides of the rotor jig 7, the push arrows 16 are moved from both sides toward the assembly position P, and each groove 15 of the elevator 9 is moved at each tip.
Push out the lock plate 5 located inside, and use the lock plate 5 to open each insertion hole 21 of the transfer jig 19.
The coil springs 4 located inside are pushed out, and each insertion hole 17 of the rotor jig 7 is pushed out as shown in FIG.

When the lock plate 5 and coil spring 4 are inserted, the contact detector 12 advances and is inserted into the insertion hole 18 of the rotor jig 7, and the missing parts of the lock plate 5 and coil spring 4 are detected.
That is, as shown in FIG. 7, the pushing arrow 16 is advanced to push the lock plate 5 so that one end thereof protrudes outside the rotor 2, and in this state, the contact detector 12 is advanced to detect the presence or absence of the lock plate 5. To detect. That is, when the contact detector 12 comes into contact with the lock plate 5 as shown in the same figure, the presence of the lock plate 5 is detected, and even if the push arrow 16 is advanced as shown in FIG. 12 does not come into contact with the lock plate 5, it is detected that the lock plate 5 is missing.

Further, the push arrow 16 and the contact detector 12 are moved backward from the state shown in FIG. 7, and the contact detector 12 is moved forward again as shown in FIG. 8 to detect the presence or absence of the coil spring 4. That is, as shown in the figure, when the contact detector 12 does not come into contact with the lock plate 5, the presence of the coil spring 4 is detected;
As shown in FIG. 10, when the contact detector 12 comes into contact with the lock plate 5, it is detected that the coil spring 4 is missing. Then, such a missing item detection operation is simultaneously performed in each lock plate hole 3 of the rotor 2 by the corresponding pushing arrows 16 and contact detectors 12, and the detection results are displayed on the display device 35.

When the missing item detection operation is completed in this way, the dummy key 14 is inserted into the rotor 2 from above by the dummy key insertion device 13, and as shown in FIG. The lock plate 5 and coil spring 4 are prevented from coming off.

The assembly of the lock plate 5 and coil spring 4 to one rotor is thus completed, the rotor jig 7 that supports the rotor 2 is moved from the assembly position P, and the next rotor jig 7 is moved to the assembly position. The assembly work is repeated as described above. If even one lock plate 5 or coil spring 4 is missing after the assembly work of the five rotors 2 is completed, the alarm device 36 emits a warning sound.

As described above, in this rotor assembly machine 1, the rotor 2 is moved by the elevator 9 on both sides of the assembly position P.
The lock plate 5 corresponding to each lock plate hole 3 is selected and inserted into each groove 15, and the coil spring 4 corresponding to each lock plate hole 3 is selected between the rotor jig 7 and the elevator 9 by the transfer jig 19. is transferred, and the lock plate 5 and coil spring 4 are inserted into each lock plate hole 3 of the rotor 2 all at once by the pushing arrow 16. Therefore, the lock plate 5 and the coil spring 4 can be inserted into the rotor 2 at the same assembly position P.

Further, the transfer jig 19 is rotated downward with one coil spring 4 housed in each insertion hole 21, and at this time, the coil spring 4 in the insertion hole 21 and the coil in the guide hole 23 above it are rotated. Since the spring 4 is engaged with the first and second locking pins 24 and 28, respectively, the coil spring 4 in the insertion hole 21 and the coil spring 4 in the guide hole 23 above it are surely pulled. be separated. Therefore, since the transfer jig 19 is moved to both sides of the rotor jig 7 with one coil spring 4 reliably accommodated in each insertion hole 21, it is possible to prevent a missing coil spring 4 from occurring. It can be prevented.

On the other hand, the contact detector 12 for detecting each item is moved from a direction perpendicular to the direction in which the lock plate 5 and the coil spring 4 are inserted into the rotor 2, and the lock plate is moved in and out of the rotor 2 based on the operation of the push arrow 16. Since the contact detector 12 is brought into contact with the rotor 2 and the missing parts of the lock plate 5 and the coil spring 4 are detected, the push arrow 16 does not become an obstacle to the missing part detection operation, and the lock plate in the rotor 2 5 and the missing coil spring can be quickly detected at the assembly position P.
