Abstract
One or more tissue web rolls are transferred from the core shaft on which they are carried by an apparatus that includes a roll change tube that is moved into coaxial alignment with one end of the core shaft and engages the end of the shaft to support it. A pusher device pushes the tissue web rolls from the core shaft onto the roll change tube. The roll change tube is then pivoted to move the roll change tube away from the core shaft to position the tissue web rolls for delivery to a downstream process, and simultaneously a core change tube is moved into coaxial alignment with the core shaft so that new cores can be pushed from the core change tube onto the core shaft.
Claims17
A method for transferring one or more tissue web rolls from a core shaft, the core shaft having a shell portion and having first and second coupling portions that respectively project beyond opposite first and second ends of the shell portion, the method comprising the steps of:
- transferring the core shaft into a core shaft change position;
- supporting the core shaft in the core shaft change position by first and second supports that engage the core shaft proximate the first and second ends of the shell portion, respectively;
- moving a roll change tube into coaxial relation with the core shaft so that a shaft-engaging end of the roll change tube at least partially engages the first coupling portion;
- removing the first support from the core shaft such that the core shaft is supported at one end by the second support and at the other end by the roll change tube;
- and
- axially pushing the one or more tissue web rolls from the core shaft onto the roll change tube.
An apparatus for transferring one or more tissue web rolls from a core shaft having a shell portion and having first and second coupling portions that respectively project beyond opposite first and second ends of the shell portion, the apparatus comprising:
- first and second supports structured and arranged to engage the core shaft proximate the first and second ends of the shell portion, respectively, so as to support the core shaft with the one or more tissue web rolls, at least the first support being movable between a position engaging the core shaft and a position disengaged from the core shaft;
- a roll change tube having a shaft-engaging end configured to fit at least partially about the first coupling portion of the core shaft, the roll change tube being configured to slidably receive the one or more tissue web rolls thereover;
- a roll core handler coupled with the roll change tube and operable to position the roll change tube in coaxial end-to-end alignment with the core shaft and to axially move the roll change tube so as to engage the shaft-engaging end of the roll change tube with the first coupling portion of the core shaft, the roll core handler and roll change tube being structured and arranged such that when the first support is disengaged from the core shaft, the core shaft and the one or more tissue web rolls are supported by the roll change tube's engagement with the first coupling portion and by the second support's engagement with the core shaft;
- and
- a pusher operable to engage the one or more tissue web rolls on the core shaft and to push the one or more tissue web rolls onto the roll change tube.
