Abstract
Abstract Mechanism for doffing large packages of roving from a mandrel of a winder is provided. The mechanism includes an upright stand mounted on a base which, in turn, is supported on wheels. A plate is slidably supported for vertical movement on the stand and is moved in a vertical direction by a fluid-operated ram, the piston rod of which is connected to the plate through a cable. A first elongate arm is pivotally mounted on the plate for pivotal movement in a vertical plane. A transverse arm extends outwardly from an end of the first arm and an elongate supporting member is connected to the transverse arm and located generally parallel to the first arm. The elongate supporting member has guide means at an end to enable the elongate member to be aligned with the mandrel to receive a roving package and a sleeve on which it is wound which are slid off the mandrel onto the elongate member. The base also has means cooperating with means on the floor adjacent the winder for positioning the overall mechanism relative to the mandrel. The elongate supporting member has resilient bands forming annular chambers around the member which are inflated to engage and hold the roving package. With the package held on the elongate supporting member, the mechanism is moved to a location spaced from the winder with the package over a pallet. The supporting member is then pivoted to a vertical position and lowered to place the package on the pallet. Air is then exhausted from the resilient bands and the elongate supporting member raised to separate it from the package.
