Cloth winder drive

摘要

A cloth winding machine has a winding shaft supported in ball bearings at the end of plural support braces positioned in different directions to reduce vibration of the winding shaft and increase its stability while winding at relatively high speeds non-symmetrical packages such as flat bolts of cloth. A cloth measuring wheel shaft encoder is connected through an electronic counter to an inverter motor control system for driving an AC electric motor so that electronic counting and motor control improves measured accuracy of the cloth segments wound onto each package, even at higher speeds. In the package mounting arrangement, the winding shaft is held in a fixed axial position and an extended shaft segment is provided with integral keyways which receive keys. The keys in turn are received in corresponding grooves on a spring mounted package support member so that the package support is rotatably received on the winding shaft in movable axial alignment therewith to permit mounting and subsequent removal of packages. The inverter motor control accelerates the AC drive motor to a predetermined speed in a predetermined acceleration time period. After a measured amount of cloth is wound onto a package and the electric motor is signalled to brake, a sensing wheel is separately braked after a predetermined time delay, which insures a smooth flow of fabric handling through the cloth winding machine and accurate measurement thereof.
