Abstract
A part is kept on standby so that it can be reliably held by a feed rod. An auxiliary feed rod is provided with an arrangement for holding a part at a fixed position in advance. The part is stopped on the advance and retraction axis of a main feed rod by the advance movement of the auxiliary feed rod where the part transferred and is held on the main feed rod.
Claims4
A parts feeding apparatus comprising:
- a main feed rod reciprocating along a first axis and having a recess formed therein for receiving a part delivered to a transfer point along the first axis;
- an auxiliary feed rod reciprocating within a sleeve along a second axis, which intersects the first axis, and forms an acute angle therewith;
- means for supplying the part to a preselected pickup point along the second axis;
- means fixed to an outward end of the auxiliary feed rod, for removably retaining the part, when the outward end is displaced to the pickup point;
- means for connecting the sleeve to the part supplying means;
- means for jointly displacing the sleeve and part supplying means along a direction parallel with the first axis;
- means for extending the auxiliary rod relative to the sleeve, along the second axis, until the part is located at the transfer point along the first axis;
- means for displacing the main feed rod to achieve engagement of the part by the main feed rod at the transfer point along the first axis;
- and
- means located in the recess of the main feed rod for releasably retaining the part while the displacing mean continues movement of the retained part beyond the engagement point.
