Abstract

An apparatus for feeding an electric-component tape which includes a carrier tape having feed holes in its lengthwise direction and which holds electric components at a predetermined pitch in the lengthwise direction, the apparatus including a drive device, two pivotable members which are reciprocatively pivotable about a common axis line, a motion converting device which converts the motion of the drive device into the respective reciprocative pivotal motions of the two pivotable members, such that when one of the two pivotable members is pivoted in one of opposite directions about the common axis line, the other pivotable member is pivoted in the other direction and, vice versa, a feed member having projections projecting outward from its circulateable circumferential surface to engage the feed holes of the carrier tape, and two one-way transmitting devices one of which transmits the pivotal motion of the one pivotable member in the one direction, to the feed member, but does not transmit the pivotal motion of the one pivotable member in the other direction, and the other of which transmits the pivotal motion of the other pivotable member in the one direction, to the feed member, but does not transmit the pivotal motion of the other pivotable member in the other direction.

Dependent claims

An apparatus for feeding an electric-component tape which includes a carrier tape having a plurality of feed holes arranged in a lengthwise direction thereof, and which holds a plurality of electric components at a predetermined pitch in the lengthwise direction, the apparatus comprising:

a drive device which provides a motion;
two pivotable members which are reciprocatively pivotable about a first common axis line;
a motion converting device which converts the motion of the drive device into the respective reciprocative pivotal motions of the two pivotable members, such that when one of the two pivotable members is pivoted in one of opposite directions about the first axis line, the other pivotable member is pivoted in the other direction and, when said one pivotable member is pivoted in said other direction, said other pivotable member is pivoted in said one direction;
a feed member which has a plurality of projections projecting outward from a circulateable circumferential surface thereof to engage the feed holes of the carrier tape;
and
two one-way pivotal-motion transmitting devices one of which is provided between the feed member and said one pivotable member and the other of which is provided between the feed member and said other pivotable member, said one one-way pivotal-motion transmitting device transmitting the pivotal motion of said one pivotable member in said one direction, to the feed member, and not transmitting the pivotal motion of said one pivotable member in said other direction, to the feed member, said other one-way pivotal-motion transmitting device transmitting the pivotal motion of said other pivotable member in said one direction, to the feed member, and not transmitting the pivotal motion of said other pivotable member in said other direction, to the feed member.

A method of feeding, with a common supplying device, each of a plurality of sorts of electric-component tapes that includes a carrier tape having a plurality of feed holes in a lengthwise direction thereof and holds a plurality of electric components at a first predetermined pitch in the lengthwise direction, and supplying the electric components, one by one, from said each electric-component tape, the first predetermined pitch being equal to a reference pitch or a product of the reference pitch and an integral number, M, not less than two, the method comprising the steps of:

engaging a plurality of projections projecting at a second predetermined pitch from an outer circumferential surface of a feed member, with the feed holes of a first sort of electric-component tape of the plurality of sorts of electric-component tapes, the first predetermined pitch of the first sort of electric-component tape being equal to the reference pitch,
driving the feed member, alternately with two reciprocative members which are reciprocatively moved in opposite directions about a common axis line, respectively, such that the feed member is driven one time by each of the alternate one-direction motions of the two reciprocative members, each one of the electric components being supplied from the first sort of electric-component tape when the feed member is driven one time,
engaging the projections of the feed member, with the feed holes of a second sort of electric-component tape of the plurality of sorts of electric-component tapes, the first predetermined pitch of the second sort of electric-component tape being equal to the product of the reference pitch and the integral number M, and
driving the feed member, alternately with the two reciprocative members, such that the feed member is driven one time by each of the alternate one-direction motions of the two reciprocative members, each one of the electric components being supplied from the second sort of electric-component tape when the feed member is driven the integral number M of times.
