Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
145 words
In apparatus for feeding empty bobbins each having a head at one end, to a bobbin changing device including spaced bobbin gripping means and means for advancing same, means for orienting bobbins for engagement of the heads by the gripping means, bobbin cArrying means mounted for pivotal movement between first and second positions and adapted to receive oriented bobbins from said orienting means when in said first position, drive means pivoting said carrying means to said second position to effect presentation of said bobbin heads to the advancing gripping means, means for urging the pivot axis of said carrying means in a direction to complete presentation of the bobbins to the gripping means at the end of the excursion of said carrying means from said first to second position, and retaining means rendering said urging means ineffective until said carrying means approaches its second position.
Claim 2
Dependent Claim
145 words
In apparatus for feeding empty bobbins each having a head at one end, to a bobbin changing device including spaced bobbin gripping means and means for advancing same, means for orienting bobbins for engagement of the heads by the gripping means, bobbin cArrying means mounted for pivotal movement between first and second positions and adapted to receive oriented bobbins from said orienting means when in said first position, drive means pivoting said carrying means to said second position to effect presentation of said bobbin heads to the advancing gripping means, means for urging the pivot axis of said carrying means in a direction to complete presentation of the bobbins to the gripping means at the end of the excursion of said carrying means from said first to second position, and retaining means rendering said urging means ineffective until said carrying means approaches its second position.
Claim 3
Dependent Claim
40 words
Apparatus according to claim 1, wherein said urging means is a spring and said retaining means comprises a ramp and means mounted for movement with said carrying means and engaging said ramp until said carrying means approaches its second position.
Claim 4
Dependent Claim
60 words
Apparatus according to claim 1, wherein said carrying means pivots about a shaft journalled in a link of a bellcrank, and said urging means is a spring arranged to bear against the other link of said bellcrank to rock same about a bellcrank axis to shift said shaft about which said carrying means pivots as same approaches its second position.
Claim 5
Dependent Claim
31 words
Apparatus according to claim 1, wherein pneumatically controlled means are mounted on said carrying means for maintaining bobbins in said carrying means during their excursions and presentation to the gripping means.
Claim 6
Dependent Claim
43 words
Apparatus according to claim 4, wherein said pneumatically controlled means comprises a double-acting pneumatic ram, the body of which is fixed on said carrying means and the piston rod of which constitutes the means for maintaining the empty bobbin in said carrying means.
Claim 7
Dependent Claim
93 words
Apparatus according to claim 4, wherein said drive means includes a double-acting pneumatic ram, the body of which is pivoted to a fixed part of the device and the piston rod of which is pivoted to the carrying means, there being also provided a distributor connected with a compressed air source which supplies the pneumatic ram of the drive mechanism and said pneumatically controlled means, and a detector for controlling the distributor and adapted to sense each passage of a gripping means and to actuate said distributor in turn to operate said ram.
Claim 8
Dependent Claim
36 words
Apparatus according to claim 6, wherein said compressed air source also operates said bolt controlling ram to retain a bobbin in said carrying means until same reaches its second position and then to release the bobbin.
Claim 9
Dependent Claim
62 words
Apparatus according to claim 1, wherein said orienting means include a holding channel for supporting oriented bobbins, said carrying means adapted to receive oriented bobbins from said channel of which it is an extension when in its first position, and means are provided to block passage of a bobbin from said channel when said carrying means is out of its first position.
Claim 10
Dependent Claim
50 words
Apparatus according to claim 8, wherein said blocking means comprise a pin mounted for pivotal movement, spring means normally urging said pin into bobbin blocking position, and means pivoting said pin out of blocking position against the force of said spring when said carrying means is in its first position.
