摘要:
A controller for a motor is configured to rotate a roll of material. The controller includes a drive speed regulator configured to generate an initial torque command based on a difference between a speed setpoint and a measured drive speed of the motor. The controller also includes an observer module configured to estimate a density error of the roll of material. The initial torque command is adjusted based on the density error to obtain a total torque command. The controller also includes a torque regulator configured to control the motor based on the total torque command.
摘要:
Generally, the present disclosure is directed to, in one embodiment, a process for controlling a converting line web. More specifically, a sheet material is provided on the converting line. A loss of control is detected in the sheet material web and the sheet material web is broken at a location upstream from the converting line web rewinder. The broken sheet material web is redirected.

Registration and inspection systems and methods for use on a winder are disclosed. The systems and methods include scanning a region proximate a winding module with one or more sensors to determine a product defect. The product defect is then associated with a winding process parameter, such as percent roll build information or the identity of the particular sensor to first detect the defect. The winding process parameter is used to classify the defect into one or more defect profiles. The defect profiles can be based at least in part on segmenting the roll build of a web onto a winding module into a plurality of inspection windows and segmenting a plurality of sensors into a plurality of inspection sensor segments.
摘要:
A method and apparatus for winding a moving web upon a mandrel is disclosed. A moving web with a leading edge is conveyed towards a mandrel. The mandrel is adapted to allow the moving web to adhere to the mandrel at a specific circumferential location on the mandrel. To enable control of the location of the mandrel, the mandrel further includes a reference input to identify the specific circumferential location. A position sensor is used to determine the position of the reference input. The position of the specific circumferential location of the mandrel is controlled with a position drive control that controls the rotational speed of the mandrel. The position drive control sets the rotational speed of the mandrel to allow transfer of the leading edge of the moving web near the specific circumferential location.
