Abstract
Abstract A parts feeder for feeding parts that are disposed on a carrier having a base tape and an adhesive tape. Parts are disposed above holes which are formed at equal intervals on the base tape, and the parts are held by an adhesive tape adhered to a lower surface of the base tape. The feeder includes a pitched feeding mechanism for intermittently feeding the carrier tape at a predetermined pitch, a separating mechanism for separating the adhesive tape from the base tape in synchronization with the feeding of the carrier tape at an adhesive tape separating stage, and a pressing mechanism for pressing the parts disposed on the base tape against the base tape prior to the separation of the adhesive tape from the base tape at the adhesive tape separating stage.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
129 words
A parts feeder for feeding parts that are disposed on a carrier tape comprising: a base tape and an adhesive tape, wherein the parts are disposed above holes which are formed at equal intervals on the base tape, and wherein the parts are held by the adhesive tape adhered to a lower surface of the base tape; a pitched feeding means for intermittently feeding said carrier tape at a predetermined pitch; means for separating the adhesive tape from the base tape in synchronization with the feeding of the carrier tape at an adhesive tape separating stage; and means for pressing the parts disposed on the base tape against the base tape prior to the separation of the adhesive tape from the base tape at the adhesive tape separating stage.
Claim 2
Dependent Claim
129 words
A parts feeder for feeding parts that are disposed on a carrier tape comprising: a base tape and an adhesive tape, wherein the parts are disposed above holes which are formed at equal intervals on the base tape, and wherein the parts are held by the adhesive tape adhered to a lower surface of the base tape; a pitched feeding means for intermittently feeding said carrier tape at a predetermined pitch; means for separating the adhesive tape from the base tape in synchronization with the feeding of the carrier tape at an adhesive tape separating stage; and means for pressing the parts disposed on the base tape against the base tape prior to the separation of the adhesive tape from the base tape at the adhesive tape separating stage.
Claim 3
Dependent Claim
47 words
The parts feeder of claim 1, further comprising: a suction means for applying a suction force to a surface of the base tape opposite a surface on which the parts are disposed, in synchronization with the feeding of the carrier tape at the adhesive tape separating stage.
Claim 4
Dependent Claim
72 words
The parts feeder of claim 1, wherein said separating means comprises: a tape passage on which said carrier tape is fed; an adhesive tape separating hole, provided on said tape passage, through which the adhesive tape is fed when separated from the carrier tape; and a separating lever positioned below said separating hole, said separating lever swung in contact with the adhesive tape to separate the adhesive tape from the base tape.
Claim 5
Dependent Claim
98 words
The parts feeder of claim 2, wherein said pressing means comprises: a slider which is movable above said tape passage and in a direction parallel to said tape passage; a component holder which is pivoted with respect to said slider, said component holder capable of pressing said parts against said base tape when pivoted; means for moving said slider towards said separating hole; and means for swinging said component holder towards the parts after said slider is moved a predetermined distance by said slider moving means so that the component holder presses the parts against the base tape.
Claim 6
Dependent Claim
26 words
The parts feeder of claim 4, wherein said component holder has a component holding leaf spring which contacts and presses the parts against the base tape.
Claim 7
Dependent Claim
58 words
The parts feeder of claim 4, further comprising: a stopper which restricts movement of said slider in a direction parallel to said tape passage after said slider has moved through said predetermined distance, wherein said component holder is swung by the force applied by said slider moving means when movement of said slider is restricted by said stopper.
Claim 8
Dependent Claim
20 words
The parts feeder of claim 6, further comprising: a spring which biases said component holder away from said carriage tape.
Claim 9
Dependent Claim
25 words
The parts feeder of claim 1, further comprising: a single hydraulic device which actuates said pitched feeding means, said separating means, and said pressing means.
Claim 10
Dependent Claim
27 words
The parts feeder of claim 1, further comprising: an adhesive tape winding means which winds the adhesive tape after the tape is separated from the base tape.
Claim 11
Dependent Claim
30 words
The parts feeder of claim 9, further comprising: a single hydraulic device which actuates said pitched feeding means, said separating means, said pressing means, and said adhesive tape winding means.
Claim 12
Dependent Claim
20 words
The parts feeder of claim 1, wherein the base tape has a series of sprocket holes on opposite edges thereof.
Claim 13
Dependent Claim
51 words
The parts feeder of claim 11, wherein said pitched feeding means comprises: a pair of sprocket wheels which engages said series of sprocket holes; and, means for rotating said pair of sprocket wheels in a manner such that the sprocket wheels rotate intermittently so that the base tape is moved intermittently.
Claim 14
Dependent Claim
150 words
A parts feeder for feeding parts that are disposed on a carrier tape comprising a base tape and an adhesive, wherein the parts are disposed above holes which are formed at equal intervals on the base tape and held by the adhesive tape adhered to a lower surface of the base tape, comprising: means for separating the adhesive tape from the base tape in synchronization with the feeding of the carrier tape at an adhesive tape separating stage; means for pressing the parts disposed on the base tape against the base tape prior to the separation of the adhesive tape from the base tape at said adhesive tape separating stage; and a suction means for applying a suction force to the surface of the base tape, opposite a surface on which the parts are disposed, in synchronization with the feeding of the carrier tape at said adhesive tape separating stage.
Claim 15
Dependent Claim
150 words
A parts feeder for feeding parts that are disposed on a carrier tape comprising a base tape and an adhesive, wherein the parts are disposed above holes which are formed at equal intervals on the base tape and held by the adhesive tape adhered to a lower surface of the base tape, comprising: means for separating the adhesive tape from the base tape in synchronization with the feeding of the carrier tape at an adhesive tape separating stage; means for pressing the parts disposed on the base tape against the base tape prior to the separation of the adhesive tape from the base tape at said adhesive tape separating stage; and a suction means for applying a suction force to the surface of the base tape, opposite a surface on which the parts are disposed, in synchronization with the feeding of the carrier tape at said adhesive tape separating stage.
