Abstract
On textile machines of the simultaneous doffing and/or donning type, full bobbins on spindles are simultaneously replaced by bare bobbins at stand-by positions in front of the spindles by utilizing the movement of an elongated beam for transportation of bobbins via chucks hung thereto, which beam rests outside the range of movement of a travelling member such as an automatic yarn knotter during the non-working cycle, along preselected courses while positively guiding the bobbins by a pilot mechanism away from any contact with surrounding machine parts.

Claims (12)
1. An improved automatic process for simultaneously doffing all full packaged bobbins from spindles of a textile machine and carrying said bobbins to an unloading station provided with pegs for holding bobbins, by way of chucks being capable of alternately engaging or disengaging with a shoulder of an axial bore of each bobbin and carried by at least a movable beam extending along said machine, comprising the steps of: displacing said chucks to positions axially above corresponding spindles when a doffing operation is required; displacing said chucks downward to said spindles holding full packaged bobbins; inserting each of said chucks into said bore of full packaged bobbins mounted on corresponding spindles; displacing said chucks upward whereby said chucks engage with said shoulder of corresponding full packaged bobbins; rotating said spindles through a prescribed angle in the direction of the normal winding after said full bobbins have been caught by said chucks; displacing each of said chucks to a position axially above corresponDing pegs mounted on said unloading station; displacing said chucks toward said unloading station and mounting said full packaged bobbins on corresponding pegs; disengaging said chucks from said bobbins by a small displacement of each of said chucks into said bore of each bobbin; and then displacing said chucks to a rest station thereof, all of said displacing motions of said chucks being carried out simultaneously with a predetermined program while guiding them positively away from any contact with surrounding machine parts.
2. An improved automatic doffing process according to claim 1, wherein said guiding is carried out by turning said bobbins under control about the axis of said beam.
3. An improved automatic process for simultaneously doffing full packaged bobbins from spindles of textile machine according to claim 1, further comprising a donning operation for automatically supplying fresh bobbins from a given standby station in front of said spindles onto spindles wherefrom said full packaged bobbins have been doffed, said donning operation being carried out by; displacing said chucks to positions axially above corresponding bare bobbins waiting at said given standby positions; displacing said chucks downward to said bare bobbins; inserting each of said chucks into said bore of bare bobbins positioned at said standby positions; displacing said chucks upward whereby said chucks engage with said shoulder of corresponding bare bobbins, displacing each of said chucks to a position axially above corresponding spindles wherefrom said full packaged bobbins have been doffed; displacing said chuck toward corresponding spindles and mounting said bare bobbins on said corresponding spindles; disengaging said chucks from said bare bobbins by a small displacement of each of said chucks into said bore of each bare bobbin; and then displacing said chucks to a rest station thereof; all of said displacing motions of said chucks being carried out simultaneously with a predetermined program while guiding them positively away from any contact with surrounding machine parts.
4. An improved automatic doffing process according to claim 3, wherein said guiding is carried out by turning said bobbins under control about the axis of said beam.
5. An improved automatic apparatus for simultaneously doffing all full packaged bobbins from spindles of a textile machine and carrying said bobbins by way of chucks capable of alternately engaging and disengaging with a shoulder of an axial bore of each bobbin, comprising a movable beam extending along said machine and turnably holding said chucks, flexible element means for displacing said beam in a direction perpendicular to the longitudinal axis thereof between a rest position and a plurality of dispositions including a position for inserting said chucks into a bore of corresponding full packaged bobbins held by spindles respectively, said flexible element means including a pair of flexible elements connected to said beam for suspending same, pilot means for piloting said chucks positively away from any contact with surrounding machine parts, and control means connected to said pair of flexible elements for controlling displacing motion of said flexible elements for moving said beam between said positions according to a predetermined program.
