Software and hardware such as part feeding and assembling devices constituting a production system are simplified with the use of a plurality of processing and assembly integrated units in which processing and assembling of parts are coupled and integrated in accordance with products to be produced. The necessities for an automatic warehouse and an automated ground vehicle are eliminated by getting rid of futility of mere movements of the parts. A fundamental idea is that a production system is constructed of units in which three sections--a section for processing a raw material, a check functional section and an assembling section--are integrally combined in accordance with the products to be produced. The parts are processed, checked and assembled by single units just in time while targeting molded parts of plastic and pressed parts.

Production system for molded and pressed parts

An apparatus for use in a system for mounting taped electronic parts on a predetermined portions of ceramics substrates and adapted for supplying the parts to a predetermined portion of the system. The apparatus has a slide table equipped with a tape pay-off arrangement and a tape feeding arrangement, a slide table and a power transmission interposed between a stationary table and the slide table, with the power transmission means being capable of transmitting a power to the tape feeding arrangement even during the sliding of the slide table. A switch-over device is drivingly connected to the power transmission means and is adapted for selectively transmitting the power to the tape feeding arrangement, in such a manner that both the selecting operation for selecting the part to be mounted next and the part feeding operation for feeding the part are conducted simultaneously.

Apparatus for supplying taped parts

A coil winding and inserting machine suitable for winding stator coils of 3-phase multipolar motors. The machine has a plurality of independently liftable tooling blades and auxiliary plates. Three winding forms are formed simultaneously or in a predetermined sequence, each being constituted by two tooling blades and one selectively lifted auxiliary plate. Three flyers corresponding to the three winding forms are rotated around these winding forms to form coils of the first pole of respective phases. Then, the flyers make a 180.degree. indexing rotation and coils of the second pole are formed in the same manner as the coils of the first pole. After the winding of all coils, the coils are inserted into the stator core together with the wedges. Accordingly, it is possible to form the coils of u, v and w phases without cutting wires between two poles of respective phases, while ensuring an equal circumferential length of coils of all phases.
