Claims
- 1. A device for charging spools successively into the socket of a winding machine, said device comprising:
- a support;
- means for advancing said support along said winding machine;
- a bin containing previously oriented spools mounted on said support and formed with a discharge slot;
- a first fork displaceable on said support and having arms flanking said discharge slot, said arms being provided with opposite rotatable grip members engageable with opposite axial ends of a spool in said bin for withdrawing an engaged spool from said slot;
- a pair of coplanar guides extending parallel to the axis of said spool engaged by said fork and disposed along the path of said spool withdrawn from said slot;
- a blowing funnel on one of said guides and an aspiration funnel disposed on the other of said guides and means for displacing said funnels along said guides for respectively dislodging a thread end from said spool engaged by said first fork and drawing said dislodged thread end into said aspiration funnel;
- means for directing said spool engaged by said first fork after the drawing of said thread end into said aspiration funnel into a respective socket of said magazine; and
- means hinged to said support for guiding said thread end drawn by said aspirator funnel to said winding machine.
- 2. The device defined in claim 1, further comprising a first electromagnet mounted on one of said arms of said first fork and an armature displacing the respective grip member toward and away from a spool disposed between said arms.
- 3. The device defined in claim 2, further comprising:
- a rubber roller formed on the grip member of the other of said arms; and
- a first motor mounted on said support and provided with a first drive roller, said first drive roller frictionally engaging said rubber roller to rotate a spool engaged by said first fork when the latter is disposed between said guides in a sense opposite to the thread winding;
- said means for advancing said support including a support rail mounted on said winding machine and frictionally engaged by a second drive roller provided on a second motor mounted on said support.
- 4. The device defined in claim 3 wherein said means for directing said spool includes a second electromagnet on said support having an armature receivable in a slot of a first indexing rail mounted on said winding machine for aligning a spool guiding trough with said socket.
- 5. The device defined in claim 4 wherein said means for guiding said thread end includes a third electromagnet on said support and having an armature receivable in a slot of a second indexing rail mounted on said winding machine and a second fork extendable toward said thread end and connected to said third electromagnet to be moved thereby in a sweeping motion across an aspirator mounted on said winding machine when said support is advanced.
- 6. The device defined in claim 5, further comprising a thread cutter disposed in the region of said aspiration funnel for cutting a thread end withdrawn thereby.
- 7. The device defined in claim 6, further comprising means including a photoreflection element responsive to the absence of a spool in one of said sockets for controlling said second electromagnet.
