Abstract
Disclosed herein is a vacuum feeding apparatus for causing a working device such as a suction pad to communicate with a vacuum port so as to enable the working device to attract and hold a work or feed it to a desired position. In the vacuum feeding apparatus, components such as a valve section, a vacuum section, a filter section, a pressure detecting section, a manifold section, etc. are produced in blocks or units respectively. These blocks indicative of the above components can selectively be used in combination. In addition, a plate mounted on a corresponding block can be used to selectively make the changeover of any one of a plurality of fluid passages defined in the block and to cut off the selected passage.
