Abstract

Apparatus for automatically producing a strip-like container housing chip-form electronic parts comprising a tape-like housing body provided with housing holes spaced thereon, a chip-form electronic part having no lead wire being housed in each of said housing holes. According to this automatic producing apparatus, a tape-like housing body is intermittently transported longitudinally, a respective chip-form electronic part being sequentially supplied by a supplying device into each housing hole provided on the housing body in the course of transportation thereof, the housing hole being sealed when the chip-form electronic part has been housed therein by a tape-like cover sheet supplied by a sheet supply device, the cover sheet being applied to the tape-like housing body by a cover sheet applying device, the aggregate of electronic parts thus produced being rolled round a reel of a winding device.

Dependent claims

Apparatus, comprising:

an intermittent feed device for intermittently feeding a tape-like housing body on a rail, said tape-like housing body having a plurality of housing holes and a plurality of feed holes formed at respective predetermined intervals therein, said tape-like housing body being fed along said rail by feed pins of said intermittent feed device which engage said feed holes;
a loading device provided along the traveling path of the tape-like housing body and adapted to load a respective chip-form electronic part into that one of said housing holes which is located at a predetermined chip insertion position each time said tape-like housing body is in a dwell period of its intermittent feed;
a cover sheet supply device for supplying at least one tape-like cover sheet to the surface of the tape-like housing body in a manner which encloses each said housing hole after a respective chip-form electronic part has been placed therein;
a cover sheet adhering device for adhering said at least one cover sheet to said housing body so as to form a strip-like container housing chip-form electronic parts;
and
a winding device for intermittently winding the strip-like container being fed from said intermittent feed device around a reel, said winding device being intermittently driven at a rate which is different than that of said intermittent feed device, said feed pins of said intermittent feed device being located downstream of said chip insertion position but upstream of said winding device relative to the path of travel of said tape-like housing body whereby said feed pins prevent forces placed on said container by said winding device from adversely affecting the relative positions of said housing hole located at said loading position and said loading device.
