Abstract
Bobbin transport devices with a swingable carrier and a bobbin receiving member adapted in a first pivot position to align with a bobbin on a winding machine, a second swingable carrier with its own bobbin receiving member which aligns with the first bobbin receiving member, a shifting member for varying the distance between the two bobbin receiving members, e.g., a piston rod adapted to engage the bobbin on a slide or trolley member for one swingable carrier, and a rack and pinion or pressurized fluid operated lift for the aforementioned structures.
Claims18
Bobbin transport apparatus comprising a first, pivotable bobbin-receiving member, means for pivoting said member about a first axis between a first position in which it is aligned with a wound bobbin on a winding machine and a second position, a second, pivotable bobbin-receiving member, means for pivoting said second member about a second axis between a first position in which it is aligned with said first member in its second position and a second position of said second member in which said wound bobbin, after its transfer from said first member to said second member, may be doffed from said second member, and transfer means for shifting said wound bobbin from said first member, while in its second position, to said second member, while in its first position.
Bobbin transport apparatus comprising a bobbin-receiving member, first means, having releasable gripping means for said member, for swinging said member and a wound bobbin thereon between a first position in which said member is aligned with a wound bobbin on a winding machine and a second position, second means, having releasable gripping means for said member, for swinging said member and the wound bobbin thereon, after release of said member by said first means, from a first position of said second means in which said member and the wound bobbin thereon may be shifted from said first means to said second means, to a second position in which said wound bobbin may be doffed from said member, and means for shifting said member and the wound bobbin thereon from said first means to said second means.
Bobbin transport and elevator apparatus comprising a vertical support member, a lift member mounted on said support member for vertical, up-and-down movement thereon, a bobbin gripper on said lift member, a follower member mounted on said vertical member and joined with said lift member for synchronous up-and-down movement with said lift member, releasable brake means on said follower member for arresting said lift and follower members on said vertical member, power drive means for moving said lift member and said follower member up or down on said support member, a spring mounted on said follower member and deflectable in the vertical directions, a handle on said spring for grasping by an operator to move said handle either up or down, and measuring means operatively associated with said spring to sense the direction of up or down movement of said handle and operatively associated with said power drive means to activate the latter in a manner seeking to maintain a substantially constant spacing between said spring and said lift member whenever said operator raises or lowers said handle.
