Title: Improvements in a method of, and mechanism for, feeding articles to machines
IPC: B65B35/26
Filed: 1959-01-16
Abstract: 904,235. Toothed gearing; ratchet mechanisms. SERAGNOLI, E., and SERAGNOLI, A., [trading as G.D. SOC. IN ACCOMANDITA SEMPLICE DI E, SERAGNOLI E A. SERAGNOLI]. Jan. 16, 1959 [Jan. 16, 1958; March 8, 1958], No. 1721/59. Classes 80 (1) and 80 (3). [Also in Group XXX] Different mechanisms are set forth for giving a turntable a stepby-step movement. Thus in Fig. 3, continuous rotation of shaft 40 is converted into a step-by-step movement of shaft 22 by the engagement of elements 38 in the groove of cam 39. Similarly the continuous rotation of shaft 40 produces an intermittent movement of shaft 27 by the engagement of elements 38a in the grooves of cam 39a. Figs. 4 and 5. The continuous rotation of shaft 56 is transmitted as an intermittent movement to shaft 64 by the engagement of cam 58 (which moves with shaft 56) with rollers 59 carried by cruciform 63 secured to shaft 64. The intermittent movement occurs when a roller 59 passes from inside the cam to outside the cam through the gap shown. Figs. 6 and 7. Continuous movement of shaft 65 is transmitted as an intermittent movement to shaft 71 by the engagement of cam 66 with disc 69, the movement taking place when elements 67 engage with teeth 70a. Similarly shaft 72 causes intermittent movement of shaft 77. Figs. 8 and 9. Continuous rotation of shaft 80 is transmitted as an intermittent rotation to pulley 79 by the engagement of teeth 84 and 85 in the apertures 83 formed in the pulley 79. The teeth 84, 85 are carried by arm 81 oscillated by eccentric 82 fast on shaft 80 so that the teeth 84 and 85 move into and out of engagement with the apertures of pulley 79. Figs. 10 and 11. The continuous movement of shaft 92 is transmitted as an intermittent movement to shaft 93 by the engagement of elements 91 in the slots of disc 94. Continuous movement of shaft 95 is transmitted as an intermittent movement to shaft 100 by the engagement of pin 96 in successive slots 98. Figs. 12 and 13. The continuous movement of shaft 104a is transmitted as an oscillatory movement to arm 107 by the engagement of cam 104 with roller 106, and arm 107 operates gear 111 to superpose its movement upon continuously-driven shaft 109 so that the resultant movement of output shaft 113 is a step-by-step rotation. Fig. 14. The continuous movements of shafts 114 and 121a are transmitted as an intermittent movement to wheel 124 by the engagement of tooth 118 in successive holes 125 of the wheel. Tooth 118 is carried by arm 116, and the tooth is given a radial movement by the engagement of cam 115 with roller 119 whilst arm 116 is given a rotary step movement by the engagement of cam 121 with roller 122. After each step, wheel 124 is held by pin 126. Figs. 15 and 16. The continuous movement of shaft 50 is transmitted as an intermittent movement to shaft 53 by the engagement of rollers 52 in the slots formed in wheel 54. Figs. 17 and 18. The continuous rotation of shaft 221 is transmitted as an intermittent movement to shaft 226 by the engagement of pins 223 in the slots of wheel 227.
