A coil spring is first inserted into the ~ hole, and then a lock plate is inserted into the same lock plate ~ hole. After the insertion operation, a missing item detection device detects whether the coil spring and the lock play 1 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 bottle into contact with the lock plate whose tip protrudes from the outer surface of the rotor due to the (=l force) of the coil spring from the direction in which the lock plate is inserted. It is designed to be detected.

The lock plate 5 and coil spring 4, which are inserted into the rotor 2 one by one, are prevented from being removed.

Next, the detailed structure of each part will be explained.

-〇- As shown in Fig. 2, the elevator 9 disposed on both sides of position P has multiple grooves 15 formed above and below, and push arrows 16 are movable in each of the 8 grooves 15. It is inserted. The tip of the pushing arrow 16 is formed in a shape along the edge of the lock plate 5 as shown in FIG. It is reciprocated within a range where it passes through the tool 7 and the tip reaches the inside of the rotor 2. In this embodiment, five push arrows 16 project from the left side of the rotor 2 and four push arrows 16 project from the right side. In the elevator 9, one lock plate 5 is inserted into each of the eight grooves 15 by a cam mechanism based on the reading result of each key mountain by the key reading device 8, and after the insertion, the push arrow 16 is inserted from the side of the elevator 9. The lock plates 5 protrude and are inserted into the rotor 2 from both elevators 9 at the same time by pushing arrows 16.

As shown in FIGS. 2 and 7, a plurality of insertion holes 17 are formed in the rotor jig 7 at the top and bottom for inserting the pushing arrows 16 from left and right, and the contact detector 12 is formed in the surface direction. An insertion hole 18 is formed for insertion.

As shown in FIG. 3, a pair of transfer jigs 19 are provided below the parts feeder 11 for transferring a predetermined number of coil springs 4 to a position P. It is attached to the tip of the rotating arm 20, which is normally held horizontally.

The rotating arm 20 is supported so as to be rotatable in the vertical direction with its base end as a fulcrum, as shown by the chain line in the figure, and also supported so as to be movable forward. The tool 19 is moved until it is located on both sides of the rotor jig 7, that is, between the rotor jig 7 and the elevator 9.

As shown in FIGS. 4 and 5, the transfer jig 19 is provided with a plurality of insertion holes 21 through which the coil springs 4 and lock plates 5 are inserted. In this embodiment, there are five locations on the left transfer jig and 19 locations on the right transfer jig.
Insertion holes 21 are formed at four locations. When the rotating arm 20 is supported in the horizontal direction, each insertion hole 2
1 is a guide member 2 extending downward from the parts feeder 11
The guide hole 23 is connected to the guide hole 23 provided in the
Inside, a large number of coil springs 4 dropped from the parts feeder 11 are stacked in series.

A first locking pin 24 that extends and retracts horizontally into the guide hole 23 and acts as a holding means for the coil spring 4 is provided at the lower end of the guide member 22, and a hydraulic cylinder 25 provided at the rear of the guide member 22 Driven by That is,
The first locking pin 24 is supported by a transmission member 26 that is supported by the guide member 22 so as to be movable back and forth, and one end of a cam 21 that rotates about a shaft 27 is engaged with the transmission member 26.
The other end of the cam 2h is connected to the hydraulic cylinder 25, and the first locking pin 24 is reciprocated so that its tip protrudes and retracts into the guide hole 23.

Second and third locking pins 28 and 29 as holding means are supported in the insertion hole 21 of the transfer jig 19 so as to be retractable. The second and third locking pins 28 and 29 are supported by a support member 30 that is supported by the rotating arm 20 so as to be movable back and forth, and the tip of the third locking pin 29 is connected to the second locking pin 28. It protrudes more forward. Then, the lower end of the transmission member 26 protrudes into the engagement recess 31 provided on the upper surface of the support member 30, and as the transmission member 26 retreats, the support member 30 retreats, and the first locking pin 24 is guided. When the second locking pin 28 goes down from the hole 23, the second locking pin 28 goes down from the insertion hole 21 with a slight delay, and the third locking pin 29 still projects into the insertion hole 21.

Therefore, when the first and second locking pins 28 and 29 sink from the guide hole 23 and the insertion hole 21 in a state where the coil spring 4 is not housed in the insertion hole 21, they are stacked in the guide hole 23. The coil springs 4 in the position move in the direction F due to their own weight, and the one coil spring 4 at the bottom moves onto the third locking pin 29 in the insertion hole 21, and in that state, the second and second locking pins move. When the locking pins 24, 28 move forward, the second locking pin 28 engages with the coil spring 4 in the insertion hole 21, and the first locking pin 24 moves forward, as shown in FIG. It is designed to engage with the coil spring 4. When the rotating arm 20 is rotated downward from this state, the transfer jig 19 is rotated downward with one coil spring 4 housed in the insertion hole 21. ing.

An engagement protrusion 32 that protrudes upward is formed at the rear of the support member 30, and when the rotating arm 20 is rotated in the vertical direction and travels, the engagement protrusion 32 moves from the sill to the collar (not shown). ) to prevent movement of the support member 30. Therefore, when the transfer jig 19 is moved to both sides of the [1-ter jig 7], the third locking pin 29 is recessed from the insertion hole 21, and the push arrow 16 is inserted into the insertion hole 21. This allows the coil spring 4 to be pushed out into the rotor 2.

The contact detector 12 is inserted into the pushing arrow 16, and after the coil spring 4 and lock plate 5 are inserted into the rerotor 2, the contact detector 12 is moved to the assembled position, and the coil spring 3 and lock plates 1 to 5 are removed. In other words, as shown in FIG.
A plurality of detectors 2 are provided vertically corresponding to the lock plate holes 3, and a front detector 12a and a rear detector 12b are supported in series on the transfer member 33 so as to be movable back and forth, and both detectors 12a are always supported. , 12b, a predetermined gap S exists between them. The transfer member 33 is transferred forward by a hydraulic cylinder (not shown). Thereafter, the tip of the front detector 12a is inserted into the insertion hole 17 of the rotor jig 7 as shown in FIG. front detector 12. a comes into contact with the lock plate 5. Then, the front detector 12a is set to lock plays 1 to 5.
The detectors 12a and 12
When the b end comes into contact with each other, an ON signal is output to a discriminating circuit to be described later.

The detection results of missing parts of the pulleys 1 to 5 and the coil springs 4 by the contact detector 12 are outputted to a discrimination circuit 34 configured in a sequence as shown in FIG.
Based on the output of the discrimination circuit 3/1, the presence or absence of the lock plate 5 and coil spring 4 of each rotor 2 is displayed on the display device 35, and if a missing item occurs, in addition to the display on the display device 35, an alarm is displayed. The device 36 is adapted to emit a warning sound.

Next, the operation of the rotor assembly machine 1 configured as described above will be explained.

When inserting the lock plate 5 and coil spring 4 into the rotor assembled on the 5th side using this rotor assembly machine 1, first insert the lock plate 5 and coil spring 4 into the five rotor jigs 7 attached to the rotor conveying device 6. The rotor 2 is supported vertically and the key is inserted into the key reader 8. When the operation of the rotor assembly Ia1 is started in this state, the key pile of the inserted key is first read by the key reader 8, and at the same time, the first rotor jig 7 is transported to the assembly position P. Then, a lock plate 5 corresponding to each key thread is selected and inserted into the matching groove 15 of the elevator 9.

Further, in the transfer jig 19 and the guide member 22, the hydraulic cylinder 25 is operated, and the first and second locking pins 24 and 28 are retreated and sunk from the guide hole 23 and the insertion hole 21. Then,
The coil spring 4 stacked in the guide hole 23 on the first locking pin 24 moves to two places above the third locking pin, and the lowermost one coil spring is placed in the transfer jig 19. 4 is stored. Then, the first and second locking pins 24,28 move forward and engage with the coil spring 4 in the transfer jig 19 and the coil spring 4 at the lowest part in the guide hole 23, and in this state, the rotating arm 20 is rotated downward. Then, the coil spring 4 in the transfer jig 19 and the guide hole 2
Since the coil springs 4 in the coil springs 3 are engaged with the second and second locking pins 24 and 28, respectively, the coil springs 4 are reliably pulled apart, and the transfer jig 19 is inserted into each insertion hole 2.
The coil spring 4 is rotated downward in a state where one coil spring 4 is housed in each spring.

After the rotating arm 20 is rotated vertically, it moves forward until the transfer jig 19 is located on both sides of the rotor jig 7 at the assembly position P, as shown in FIG. At this time, the second and third locking pins 28 and 29 in the transfer jig 19 are sunk into the respective insertion holes 21, and the respective insertion holes 21 are connected to the platform groove 15 of the elevator 9 and the insertion hole 17 of the rotor jig 7. It becomes a state where there is no communication.

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 the lock plates 5 located in each groove 15 of the elevator 9 are moved at each tip. The coil springs 4 are pushed out and positioned in the respective insertion holes 21 of the transfer jig 19 with the lock plays 1 to 5.
are pushed out, and the lock plays 1 to 5 and the coil spring 4 are inserted into the lock plate hole 3 of each rotor 2 from each insertion hole 17 of the rotor jig 7, as shown in FIG.

When the lock plate 5 and coil spring 4 are inserted, the contact detector 12 moves forward 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.

41 That is, as shown in FIG. 7, by advancing the pushing arrow 16 and pushing the lock plate 5, one end thereof protrudes outside the rotor 2, and in this state, the contact detector 12 is advanced and locked. The presence or absence of plate 5 is detected. That is, as shown in the figure, when the contact detector 12 comes into contact with the lock plate 5, the presence of the lock plate 5 is detected, and the ninth
Even if the push arrow 16 is moved forward as shown in the figure, the contact detector 1
2 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 back from the state shown in FIG. 7, and the contact detector 1 is moved back as shown in FIG.
2 is advanced to detect the presence or absence of the coil spring 4.

That is, as shown in FIG. 10, when the contact detector 12 does not come into contact with the lock plate 5, the presence of the coil spring 4 is detected, and as shown in FIG.
The blade that came into contact with the Kotoku plate 5 is the coil spring 4.
A missing item is detected. 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 using the dummy key insertion device 13.
are inserted, and each lock plate 5 is inserted as shown in FIG.
The dummy key 14 is penetrated to prevent the lock plate 5 and fill spring 4 from coming off from the rotor 2.

As described above, the set of lock plays 1 to 5 and coil spring 4 for the rotor 1 (=I) is completed, and the rotor jig 7 that supports the rotor 2 is moved from the assembly position P, and the next assembly is completed. The rotor jig 7 is transported to the assembly position P, and the assembly work as described above is repeated.
If at least one lock plate 5 or coil spring 4 is missing after the assembly of the rotor 2 is completed, the alarm device 36 will emit a warning sound.

As described above, in this rotor assembly 1111, the lock plates 1 to 5 corresponding to each lock plate hole 3 of the rotor 2 are selected by the elevator 9 on both sides of the assembly position P and inserted into each corner 15, The coil springs 4 corresponding to each lock plate hole 3 are transferred between the rotor jig 7 and the elevator 9 by the transfer jig 19, and the lock plate i-5 and the coil springs 4 are transferred to the rotor at once by the push arrow 16. 2 into each lock plate hole 3.

Therefore, the lock plate 5 and coil spring 4 can be inserted at position P when assembling the rotor 2 in the same manner.

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 second and second locking pins 2/I and 28, the coil spring 4 in the insertion hole 21 and the coil spring 4 in the guide hole 23 above it are securely connected. separated. Therefore,
Make sure that one coil spree 1 is inserted into each insertion hole 21.
8= Since the transfer jig 19 is moved to both sides of the rotor jig 7 with the ring 4 housed, it is possible to prevent the coil spring 4 from being out of stock.

On the other hand, the contact detector 12 for detecting missing items 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 lock plate 5 and the coil spring 4, the missing parts of the lock plate 5 and the coil spring 4 are detected.
This does not impede the missing parts detection operation, and the missing parts of the lock plate 5 and the coil spring in the rotor 2 can be quickly detected at the assembly position P.

(Effects of the Invention) As described in detail above, the present invention provides a rotor in which a rotor is supported in a vertical direction, and a coil spring and a lock plate are inserted horizontally into lock plates 1 through holes formed in the rotor using push arrows. It is possible to provide a new missing item detection device that can detect missing parts of a lock plate and a coil spring by bringing a contact detector into contact with a lock plate while operating the lock plate with a push arrow in an assembling machine. Demonstrates excellent effects.
