摘要： 1,249,739. Discharging articles from shoots. USM. CORP. 27 March, 1969 [28 March, 1968], No. 15989/69. Heading B8S. [Also in Division B3] A machine for mounting components C on workpieces B includes automatic feed means 8. The components C are supplied from a'dispensable magazine 230, which contains several vertical stacks of components and is provided with lugs, which slide within a notch 234. The magazine is moved stepwise by gears (180), (182), (200), (202), Fig. 5 (not shown), and operation of a switch LS10 indicates to the feed mechanism that a stack is empty, thereby withdrawing a plunger (222) and allowing rotation of the gears so that a new stack of components is aligned with a shoot 20, whereupon the plunger is returned. The bottom component C of the stack is held by a spring-loaded rod 28 towards the top of the shoot 20. An air motor 32 is actuated to withdraw a rod 30, which abuts the other end of the spring 36, loading the rod 28, and a spring 26 pivots a member 24 so that a lower limb thereof enters the shoot. As the rod 30 withdraws, the spring pressure is reduced and the component stack moves down on to the lower limb of the member 24. The rod 30 is then advanced, thereby loading the rod 28 to hold the stack and pivot the member 24, whereupon the bottom component falls on to a gate 40. A cylinder 42 moves the component laterally so that a lead straightening operation may be performed. Should no component be present, the switch LS10 is closed, thereby resetting the apparatus for a new cycle. An air motor 70 opens the gate 40 when a component is present and it moves down the portion 21 of the shoot, coming to rest on a bar 84.
