Abstract
Abstract An inexpensive device for acurately and intermittently feeding a component transporting tape to a pickup station of a circuit board assemblying apparatus wherein a yieldable actuator intermittently drives a tape feed pawl until stopped by an adjustable limit stop to precisely position each component. A takeup reel for removing a retainer strip from the transport tape is yieldably driven by the tape through a belt which is controlled by a constant tension device.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
117 words
A device for intermittently feeding components to a pickup station of a component assemblying apparatus having a reciprocating actuator, said components being carried by a transport tape having feed perforations there along, comprising a tape guide member, a feed pawl reciprocated by said actuator, a drive tooth on said pawl, spring means urging said pawl to extend said tooth through a said perforation and into guided engagement with said guide member, said tooth having a driving edge engagable in a said perforation for driving said tape during advancement of said pawl and a camming edge engagable with an edge of said last mentioned perforation during return of said pawl whereby to disengage said tooth from said perforation.
Claim 2
Independent Claim
117 words
A device for intermittently feeding components to a pickup station of a component assemblying apparatus having a reciprocating actuator, said components being carried by a transport tape having feed perforations there along, comprising a tape guide member, a feed pawl reciprocated by said actuator, a drive tooth on said pawl, spring means urging said pawl to extend said tooth through a said perforation and into guided engagement with said guide member, said tooth having a driving edge engagable in a said perforation for driving said tape during advancement of said pawl and a camming edge engagable with an edge of said last mentioned perforation during return of said pawl whereby to disengage said tooth from said perforation.
Claim 3
Dependent Claim
75 words
A device as defined in claim 1 comprising a detent pawl, means for urging said detent pawl into engagement with said tape, said detent pawl having a detenting edge engagable in a said perforation to prevent retrograde movement of said tape from said station and a camming edge engagable by said last mentioned perforation during advancement of said tape toward said station for moving said pawl out of detenting engagement with said last mentioned perforation.
Claim 4
Independent Claim
163 words
A device for intermittently feeding components to a pickup station of a component assemblying apparatus having a reciprocating actuator, said components being carried along a transport tape, said tape including a component carrying strip having feed perforations therealong and a retainer strip removably attached to said carrier strip which comprises means for guiding said tape toward said station, a feed pawl having a drive tooth engagable with said perforations, drive means operable by said actuator during advancement thereof for advancing said pawl to drive said tape toward said station, means comprising a tape guide member, spring means urging said pawl to extend said tooth through a said perforation and into guided engagement with said guide member, a detent pawl having a detent tooth, spring means urging said detent pawl to extend said detent tooth through a said perforation, and means including said guide member for stripping said retainer strip from said carrier strip and for drawing said retainer strip over said guide member.
Claim 5
Independent Claim
163 words
A device for intermittently feeding components to a pickup station of a component assemblying apparatus having a reciprocating actuator, said components being carried along a transport tape, said tape including a component carrying strip having feed perforations therealong and a retainer strip removably attached to said carrier strip which comprises means for guiding said tape toward said station, a feed pawl having a drive tooth engagable with said perforations, drive means operable by said actuator during advancement thereof for advancing said pawl to drive said tape toward said station, means comprising a tape guide member, spring means urging said pawl to extend said tooth through a said perforation and into guided engagement with said guide member, a detent pawl having a detent tooth, spring means urging said detent pawl to extend said detent tooth through a said perforation, and means including said guide member for stripping said retainer strip from said carrier strip and for drawing said retainer strip over said guide member.
Claim 6
Dependent Claim
143 words
In a component assemblying apparatus having means for intermittently feeding a component transport tape toward a component pickup station, said tape including a component carrier strip and a component retainer strip removably attached to said carrier strip; a device for stripping said retainer strip from said carrier strip comprising a takeup reel for said retainer strip, a pulley connected to said reel, a cog wheel, mean for rotating said cog wheel, a cog belt having a driving strand and a driven strand, said belt being loosely wrapped over said pulley and in driving connection with said cog wheel, and a belt tensioning device for yieldably varying the tension in said driving strand whereby to vary the torque applied to said pulley by said belt in accordance with the drag imposed on said retainer strip upon stripping said retainer strip from said carrier strip.
Claim 7
Dependent Claim
143 words
In a component assemblying apparatus having means for intermittently feeding a component transport tape toward a component pickup station, said tape including a component carrier strip and a component retainer strip removably attached to said carrier strip; a device for stripping said retainer strip from said carrier strip comprising a takeup reel for said retainer strip, a pulley connected to said reel, a cog wheel, mean for rotating said cog wheel, a cog belt having a driving strand and a driven strand, said belt being loosely wrapped over said pulley and in driving connection with said cog wheel, and a belt tensioning device for yieldably varying the tension in said driving strand whereby to vary the torque applied to said pulley by said belt in accordance with the drag imposed on said retainer strip upon stripping said retainer strip from said carrier strip.
Claim 8
Dependent Claim
24 words
A device as defined in claim 4 wherein said last mentioned means comprises means for deflecting said driving strand different amounts around said pulley.
Claim 9
Dependent Claim
17 words
A device as defined in claim 4 wherein said rotating means comprises means driven by said tape.
Claim 10
Dependent Claim
34 words
A device as defined in claim 4 wherein said belt tensioning means comprises spring means for deflecting said driving strand toward said driven strand whereby to wrap said belt different amounts around said pulley.
Claim 11
Dependent Claim
35 words
A device as defined in claim 4 wherein said belt tensioning means comprises spring means for deflecting said driving strand toward said driven strand to yieldably advance said pulley whereby to tense said retainer strip.
