(4) Indexing applications with: FEEDING WITH STOPPER (Feed frequency: N = Up to 300 cycles/min.) (Feed angle: 0 = up to 90°) In this application, a stopper holds the material to be indexed at a position just before the feed end point, providing a fixed feeding pitch. As soon as the material hits the stopper, a torque shock load larger than the torque required for feeding is applied to the feeding roll which is still rotating. Figure 19 below shows an example of a Cam Clutch used in a bolt header. The wire is fed intermittently by a Cam Clutch mounted on a grooved feed roll. Since the feed length of the wire is set longer than necessary, the fed wire hits the stopper which has been set at a position where the wire is fed to the necessary length. The reactive force this generates acts as a vibrating shock load upon the Cam Clutch. It is therefore necessary to consider this when selecting a Cam Clutch.
(5) Indexing applications with: SPEED CHANGE (Feed frequency: N = Up to 300 cycles/min.) (Feed angle: 0 = Up to 90°; N × 0 = 20,000 max.) In an intermittent feed mechanism that uses one or more Cam Clutches, the speed of the driven side is changed steplessly by changing the feed angle. Figure 20 below shows an example of a manure spreader. The amount of manure to be sprinkled varies depending on the field conditions. The chain conveyor is driven by an intermittent Cam Clutch feeding action and the manure loaded on the cart is fed in bits to the continuously rotating sprinkling vanes. The manure to be sprinkled can thus be kept at the optimum amount by adjusting the amount of manure to be fed. The feed amount (or angle of the Cam Clutch) can be controlled steplessly while the sprinkler is operating.
