Lockout cam for a bedroll of a rewinder

机译:锁定凸轮,用于复卷机的底辊

摘要

A rewinder includes a lockout cam for controlling the actuation of transfer pins and transfer pads on the bedroll of a rewinder. The transfer pins and transfer pads are mounted on a rotatable pin shaft and a rotatable pad shaft, respectively. A cam follower assembly on the pin shaft is engageable with a pin cam for controlling movement of the transfer pins. A cam follower assembly on the pad shaft is engageable with a pad cam for controlling movement of the transfer pads. The lockout cam is rotatably mounted relative to the bedroll. A first portion of the lockout cam is engageable with the cam follower assemblies for preventing the pin and pad cam follower assemblies from engaging the pin cam and the pad cam, respectively. A second portion of the lockout cam permits the pin and pad cam follower assemblies to engage the pin cam and the pad cam, respectively. During most of the winding cycle, the lockout cam is rotated at the same speed as the bedroll so that the first portion of the lockout cam engages the cam follower assemblies and prevents the cam follower assemblies from engaging the pin and pad cams. Near the end of the winding cycle, the lockout cam is rotated at a different speed than the bedroll so that the second portion of the lockout cam is aligned with the cam follower assemblies and the pin and pad cam follower assemblies engage the pin and pad cams, respectively.
