(54) | Automatic dispenser for flexible discs |
(57) An automatic dispenser for dispensing a flexible rubber collar over a shouldered
pin comprises a magazine 33 for holding a stack of collars. A carrier 31 has a recess
45 provided with a shoulder 46 which resists movement of a disc but does not prevent
movement of a disc through the carrier plate 31 on the application of sufficient axial
force. An actuator constituted by a piston 14 is coupled to the carrier 31 to effect
rotation thereof so as to align the disc held in the recess 42 with a hollow plunger
52. Advancement of the piston causes the hollow plunger 52 to force the disc through
the aperture defined by the shoulder 46, the disc flexing under the action of the
plunger. The plunger can receive the spigot or head of the pin so that the collar
may be inserted on the spigot or pin as far as a shoulder thereon. |
