Abstract

The present invention provides an apparatus of feeding workpieces, capable of preventing generated contaminants from adhering workpieces and improving stabilization in a discharge rate of the workpieces while having advantage of the drum type. The apparatus has a mesh drum, a rotary drive and an angle adjuster. The mesh drum has a mesh circumferential wall that defines a space for accommodating workpieces, the mesh drum is configured to be rotated and tilted by the rotary drive and the angle adjuster. The mesh drum has a mesh size of the mesh circumferential wall being set according to form of the workpieces to ensure the separating of the workpieces.

First claim

What is claimed is:

1. An apparatus of feeding workpieces, comprising:
a mesh drum having a mesh circumferential wall that defines a space for accommodating workpieces, the mesh drum rotatably and tiltably supported with an apparatus base to separate and discharge the workpieces;
a rotary drive that drives the mesh drum to be rotated;
an angle adjuster that drives the mesh drum to be tilted;
as drum base being a part rotatably and tiltably connected to the apparatus base and driven by the rotary drive and the angle adjuster, the drum base having a cylindrical shape to enclose the mesh drum while maintaining an airgap between the mesh drum and the drum base; and
an engagement/disengagement part fixing an opening of the mesh drum enclosed in the drum base to an opening of the drum base,

wherein
the mesh drum has a mesh size of the mesh circumferential wall being set according to form of the workpieces to ensure the separating of the workpieces, and
the mesh drum is detachably supported with the apparatus base.
