Abstract
This device for supporting cops in circular knitting machines, particularly in fixed needle cylinder knitting machines, comprises a plurality of frames which are arranged close together around the machine axis and carry the machine feed cops. Each frame is translatable parallel to itself along a direction having a substantially parallel component to the machine axis from a first raised working position to a second depressed position away from the machine axis to enable a floor-based operator to get at the cops of one frame when the latter occupies the second position; the device also comprises hooks for locking the frames in the first position.
Claims13
A device for supporting cops in circular knitting machines, particularly in fixed needle cylinder knitting machines, comprising a bearing member defining a device central axis, a plurality of frames for supporting feed cops radially arranged around said bearing member, frame translation means connected to said bearing member and said frame for moving each said frame in a direction having a component substantially parallel to said device central axis and a component substantially perpendicular to said device central axis, said device further comprising controlled operation frame locking means for selectively and removably connecting said frame with said bearing member, thereby each said frame translating between a first raised working position, wherein said frame is arranged close to said bearing member and is locked by said frame locking means, and a second depressed cops doffing position, wherein said frame is arranged away from said bearing member, said device further comprising safety means including a plurality of rest portions and a plurality of delimiting rods extending radially from said bearing member and defining a plurality of sectors for laterally delimiting said frames, said frames having lateral cooperation means engaging with said delimiting rods, and being laterally locked on opposite sides at said first position, said rest portions being slidingly arranged on said delimiting rods and movable between a first interference point of said delimiting rods and a second noninterference point, said lateral cooperation means comprising lateral projections bearing on said rests in said first position of said frames with said rest at said first interference point.
In combination, a circular knitting machine, and a device for supporting cops in said circular knitting machine, said device comprising defining a device central axis, a plurality of frames for supporting feed cops radially arranged around said bearing member, frame translation means connected to said bearing member and said frame for moving each said frame in a direction having a component substantially parallel to said device central axis and a component substantially perpendicular to said device central axis, said device further comprising controlled operation frame locking means for selectively and removably connecting said frame with said bearing member, thereby each said frame tarnslating between a first raised working position, wherein said frame is arranged close to said bearing member and is locked by said frame locking means, and a second depressed cops doffing position, wherein said frame is arranged away from said bearing member, said device further comprising a plurality of delimiting rods extending radially from said support shaft and defining a plurality of sectors for laterally delimiting said frames, said frames having lateral cooperation means engaging with said delimiting rods, and being laterally locked on opposite sides at said first position.
