Top-cover-tape feeding apparatus and top-cover-tape treating apparatus

A top-cover-tape feeding apparatus for feeding two top cover tapes respectively peeled from two electric-component tapes each of which additionally includes a carrier tape having a plurality of pockets which are formed in a lengthwise direction of the carrier tape, which accommodate a plurality of electric components, respectively, and whose respective upper openings are closed with a corresponding one of the two top cover tapes, the apparatus comprising:

• two pairs of tape-feed rotatable members, the two tape-feed rotatable members of each of said two pairs being rotatable about respective axis lines parallel to each other, and having respective outer circumferential surfaces which cooperate with each other to pinch a corresponding one of the two top cover tapes respectively peeled from the two electric-component tapes;
• two rotary drive devices each of which comprises an electric motor as a drive source thereof and which rotates at least one of the two tape-feed rotatable members of a corresponding one of said two pairs;
• a frame which supports the two pairs of tape-feed rotatable members and the two rotary drive devices, such that the two rotatable members of one of said two pairs and the two rotatable members of the other pair are arranged in a widthwise direction of the frame that is parallel to the respective axis lines about which the two rotatable members of said one pair are rotatable and the respective axis lines about which the two rotatable members of said other pair are rotatable, and such that the respective electric motors of the two rotary drive devices are arranged in a direction perpendicular to the widthwise direction of the frame and each of the two electric motors is connected to said one of the two rotatable members of a corresponding one of said two pairs via a rotation-transmitting shaft member and two universal joints provided at opposite ends of the rotation-transmitting shaft member;
• at least one of the two tape-feed rotatable members of each of said two pairs having a scraper groove which is formed in the entire outer circumferential surface thereof, in an intermediate portion thereof in an axial direction thereof parallel to the widthwise direction of the frame;
• and
• at least two scrapers each of which is provided on at least an outlet side of the two tape-feed rotatable members of a corresponding one of said two pairs, in a tape-feed direction in which a corresponding one of the two top cover tapes is fed, such that a portion of said each scraper is fitted in a portion of the scraper groove that corresponds to a position where the respective outer circumferential surfaces of the two rotatable members of said corresponding one pair pinch said corresponding one top cover tape, so that said each scraper prevents said corresponding one top cover tape from clinging to said at least one of the two rotatable members of said corresponding one pair.
