Improvements in an apparatus for removing full bobbins from a filament winder and install empty tubes on said winder.

摘要

A doffing apparatus used in combination with a row of winders each of which winds filamentary material upon a tube carried by a rotary spindle of the winder to form a package. The apparatus comprises a carrier mounted for movement generally parallel to and above the row of winders. A column is mounted on said carrier for horizontal movement. A package exchange arm is mounted on said column for up-and-down movement and is alignable with the winder spindle so that the package can be transferred to the package exchange arm. A tube exchange arm is mounted on the column for up-and-down movement and is alignable with the spindle so that a tube on the tube exchange arm can be transferred to the spindle. A shuttle is spaced horizontally from and vertically above the row of winders, and includes a package transfer arm and a tube transfer arm. The package exchange and tube exchange arms are moved along the column to the level of the shuttle. The column is moved horizontally toward the shuttle so that the package can be transferred from the package exchange arm to the package transfer arm and a tube can be transferred from the tube transfer arm to the tube exchange arm. The shuttle is transferred to a remote station where the package is removed from the package transfer arm and a tube inserted on the tube transfer arm.
