  Next, when one of the inner link plates 2 that has finished fitting the rollers 6 and 6 to the bushes 5 and 5 in the above process is sent to a position directly below the punches 26 and 26 by the operation of the component transfer blade 85 and stopped. Then, one component clamping supply body 39 advances in a direction perpendicular to the component transfer path 22, and the other inner link plate 3 of the other inner link plate supply hopper 32 is clamped by the other component clamping supply body 42. To do. Then, the other inner link plate 3 is moved to a position directly below the punches 26 and 26 while being sandwiched, and the pressurization of the punches 26 and 26 leads to the bush fitting holes 4 and 4 of the other inner link plate 3. When the fitting of the bushes 5 and 5 is finished and the punches 26 and 26 start to rise, they return to their original positions again.

  Next, when both of the inner link plates 2 and 3, which have completed the above-described process by the operation of the component transfer blade 85, are sent to a position just below the punch 27 and stopped, the other inner link plate is pressed by the pressurization of the punch 27. 3 is pushed further deeper, and the fitting of the bushes 5 and 5 into the bush fitting holes 4 and 4 is completed. When this is finished, the punch 27 rises.

  Next, when both of the inner link plates 2 and 3, which have finished the above-described process by the operation of the component transfer blade 85, are sent to a position below the punches 28 and 28 and stopped, one of the inner link plates 58 is placed on the outer link plate moving supply table 58. One outer link plate 8 of the outer link plate supply hopper 33A is placed, and the O-rings 7, 7 of the O-ring supply hopper 33 are placed at the positions of the bush fitting holes 10, 10. The one outer link plate 8 is positioned below the adjacent inner link plates 2, 3, 2, and 3 by the movement of the outer link plate moving / supplying base 58.

  Next, the pins 11 and 11 of the pin supply hoppers 34 and 34 are supplied to positions just below the punches 28 and 28 by the operation of the pin movement supply plates 66, 67 and 68. Then, by pressing the punches 28, 28, the pins 11, 11 are moved from the bushes 5, 5 of the other upper inner link plate 3, 3 to the pin fitting holes 10, 10 of the lower outer link plate 8. Mating.

  Next, both the inner link plates 2 and 3 and the one outer link plate 8 that have completed the above-described steps by the operation of the component transfer blade 85 are sent to the next step, and the components are pushed up below the component transfer path 22. One outer link plate 8 positioned on the lower side is gradually raised along the component transfer path 22 by the transfer platform 79, and the other inner link plate 3 positioned on the upper end of the pins 11, 11 is positioned on the upper side. 3 is protruded from the bushes 5 and 5.

  Next, the O-rings 7 and 7 of the O-ring supply hoppers 35 and 35 are placed on the upper surfaces of the other inner link plates 3 and 3 positioned on the upper side by the O-ring transfer device 80.

  Next, the other outer link plate 9 of the other outer link plate supply hopper 36 is aligned with the pin fitting holes 10 and 10 and the pins 11 and 11 by the operation of the other outer link plate moving supply plate 81. And place it on the pins 11 and 11.

  Next, both the inner link plates 2 and 3 and both the outer link plates 8 and 9 that have completed the above-described process are moved to a position directly below the punches 29 and 29 by the operation of the component transfer blade 85. Then, the pins 11 and 11 are fitted into the pin fitting holes 10 and 10 of the other outer link plate 9 by pressurization of the punches 29 and 29. The entire assembly process is completed by the above processes, and the O-ring chain is completed.
