Definitions

  • a full an storage station is positioned in lineal arrangement in front of the drafting rolls and coiler. It is spaced from the can filling station by an operator access platform in the form of a horizontal plate across which a full can is doifed by engagement with its bottom rim.
  • the plate has a suitable switch for sensing the presence of any weight on it so that a full can will not be doffed while an operator is standing on the plate as during drafting roll or coiler servicing.
  • An empty can ready station is positioned beside filling station and one or more empty can storage stations are provided in lineal arrangement parallel to that of the drafting rolls and full can storage station, producing a U-shaped path of can travel with the filling and ready stations at the base of the U and the empty and full can storage stations at its ends.
  • Can doffing and donning devices are provided together with suitable controls for operation of the apparatus, which are integrated with the operation of the drawing rolls and coiler by a yardage counter which senses a predetermined quantity of sliver delivered to a can at the filling station and actuates the controls at appropriate intervals as well as arresting the delivery of sliver and severing it so that the coiling operation can begin in each new can with a fresh end of sliver.
  • a yardage counter which senses a predetermined quantity of sliver delivered to a can at the filling station and actuates the controls at appropriate intervals as well as arresting the delivery of sliver and severing it so that the coiling operation can begin in each new can with a fresh end of sliver.
  • This invention relates to textile processing apparatus and more particularly to a novel can storage and changing apparatus for moving to and from a can filling station a succession of cans for filling with coiled sliver from a coiler such as is used at the delivery end of a textile sliver drawing frame of the like.
  • any stoppage of the fiber delivery rolls during changing of a full can to an empty can can be short enough so that the cards may continue to operate during the can dofling cycle, and so that the practical ice problems in storing any substantial amount of the sliver being produced by the cards while the delivery rolls are stopped be avoided.
  • Still another problem with such machines has to do with the difficulty of operator access to the drafting and coiler elements at the output end thereof in which it has heretofore been necessary for the operator first to move one or more full cans and to interfere, as well, with the doffing functions of the apparatus for an undue amount of time, such that the cards almost inevitably stop with the resulting deleterious effect on the sliver.
  • a novel can changing apparatus having a plurality of can stations, not only including a can filling station and an empty can ready station, but also a reservoir for empty cans and storage for full cans, together with operating and control means therefor providing fully automatic operation with a minimum degree of operator supervision.

  • can donning means For moving an empty can from the ready station to the filling station across the base of the U, can donning means is provided, such having a retracted position and being responsive to appropriate sensing means such as the can dofling means sensing means to don an empty can from said ready station to said filling station.
  • Can donning means sensing means responsive to the retracted position of said can donning means may be provided.
  • conveying means are provided responsive to the ready can sensing means in the absence of a ready can at said ready station and preferably responsive to the can donning sensing means if present.
  • sliver quantity sensing means such as a yardage counter is provided for sensing a predetermined quantity of sliver delivered to a can at said filling station, as well as means such as a clutch responsive to said sliver quantity sensing means for arresting the delivery of sliver from the sliver delivery rolls and means preferably responsive to a position of a can changing element for restarting the delivery rolls.
  • means are provided responsive to the sliver quantity sensing means for severing sliver beyond said delivery rolls, so that the coiling operation can begin in each new can with a fresh end of sliver.
  • the invention meets the problem of access to the drafting elements and coiler at the delivery end thereof in a novel manner by spacing the full can storage station in lineal arrangement with the drafting elements and coiler a distance from the can filling station sufiicient to provide an operator access station, such access station having thereat a horizontal plate member providing a firm footing for an operator, while permitting movement of a full can thereacross from the filling station to the full can output station, the doffed filled can thereon being advanced to the full can storage position by novel means engaging its bottom leading edge lower rim.
