Abstract
Abstract An automatic winding machine includes: a multiplicity of winding stations; a conveyor belt guided along the winding stations for supplying individual spools in axial alignment to the winding stations in a given transport direction along a given transport plane; each of the winding stations including: a run-off position and a reserve position in which respective spools are maintained in readiness, a controllable deflector for conducting spools base-first from the conveyor belt to the reserve position, a chute for guiding spools from the reserve position to the run-off position, a spool receiving trough disposed below the given transport plane and substantially parallel to the given transport direction, a controllable thread suction device, and means for shifting the spool receiving trough from a relatively flat position to a relatively upright position in which a tip of a tube of a spool in the spool receiving trough approaches the thread suction device and the spool is aligned in the chute.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
156 words
Automatic winding machine, comprising: a multiplicity of winding stations; a conveyor belt guided along said winding stations for supplying individual spools in axial alignment to said winding stations in a given transport direction along a given transport plane; each of said winding stations including: a run-off position and a reserve position in which respective spools are maintained in readiness, a controllable deflector for conducting spools base-first from said conveyor belt to said reserve position, a chute for guiding spools from said reserve position to said run-off position, a spool receiving trough disposed below said given transport plane and substantially parallel to said given transport direction, a controllable thread suction device, and means for shifting said spool receiving trough from a relatively flat position to a relatively upright position in which a tip of a tube of a spool in said spool receiving trough approaches said thread suction device and the spool is aligned on the chute.
Claim 2
Dependent Claim
156 words
Automatic winding machine, comprising: a multiplicity of winding stations; a conveyor belt guided along said winding stations for supplying individual spools in axial alignment to said winding stations in a given transport direction along a given transport plane; each of said winding stations including: a run-off position and a reserve position in which respective spools are maintained in readiness, a controllable deflector for conducting spools base-first from said conveyor belt to said reserve position, a chute for guiding spools from said reserve position to said run-off position, a spool receiving trough disposed below said given transport plane and substantially parallel to said given transport direction, a controllable thread suction device, and means for shifting said spool receiving trough from a relatively flat position to a relatively upright position in which a tip of a tube of a spool in said spool receiving trough approaches said thread suction device and the spool is aligned on the chute.
Claim 3
Dependent Claim
22 words
Automatic winding machine according to claim 1, including a controllable spool releasing device disposed between said spool receiving trough and said chute.
Claim 4
Dependent Claim
33 words
Automatic winding machine according to claim 1, wherein said spool receiving trough includes a sensor sensing the presence of a spool, said sensor issuing a spool request signal and a spool receipt signal.
Claim 5
Dependent Claim
13 words
Automatic winding machine according to claim 3, wherein said sensor controls said deflector.
Claim 6
Dependent Claim
28 words
Automatic winding machine according to claim 3, wherein said spool receiving trough has side walls and said sensor is a reflecting light gate disposed in said side walls.
Claim 7
Dependent Claim
60 words
Automatic winding machine according to claim 1, including an upright stationary sheet metal trough serving as a stop for a base of the spool when said spool receiving trough is in said relatively flat position, and forming a sleeve with said spool receiving trough preventing tipping of the spool when said spool receiving trough is in said relatively upright position.
Claim 8
Dependent Claim
63 words
Automatic winding machine according to claim 1, wherein said spool receiving trough has an edge, and including a sheet metal guide extending at an incline relative to the horizontal from said conveyor belt to said edge, said sheet metal guide including a trough-shaped part forming an elongation of said spool receiving trough when said spool receiving trough is in said relatively upright position.
