Abstract

RFID and other identification tools can be used to convey detailed information about roll goods in order to facilitate improved operation and control of processes using the rolls. The feed forward system can use data from single rolls or from groups of rolls with one or more tags identifying the properties of the group or the individual members of the group.

RFID-Assisted Feed Forward Systems for Roll Goods

Abstract

RFID and other identification tools can be used to convey detailed information about roll goods in order to facilitate improved operation and control of processes using the rolls. The feed forward system can use data from single rolls or from groups of rolls with one or more tags identifying the properties of the group or the individual members of the group.

Overview

Rolls of nonwoven, film, and paper materials are commonly used as raw materials in the production of many articles. For example, disposable diapers may employ rolls of breathable cover materials, highly porous inner linings, hook and loop materials for fastening systems, elastomeric components, tissue webs, and other webs for their manufacture. For any of these components, the properties of the material may vary from batch to batch, or even with a single roll. Standard settings used in the processes that employ the roll goods typically are not adapted to prevent difficulties that might arise from variability in roll properties. Previously, Kimberly-Clark researchers have discussed intelligent manufacturing systems in which event-based information obtained during the production of roll goods can be used in a feed-forward process control system to adapt operating conditions of better runnability of the final product (see, for example, US Patent Publication No. US20030155415-A1, "Communication between Machines and Feed-Forward Control in Event- Based Product Manufacturing," published Aug. 21, 2003 by Markham et al.). We now propose several extensions of such concepts for improved manufacturing and roll handling.

In general, an RFID tag or other identification means (bar code, etc.) will be associated with a roll of material to be used in a manufacturing process to make a product. The tag can contain identification information that can serve as a pointer in a database to allow details about the roll to be retrieved, or it can contain the information directly by writing, for example, roll information to a read-write RFID tag. The roll information can include details of product type, roll size and mass, material composition, event-based data describing events such as splices or quality defects (e.g., location of the quality defect), basis weight and other material properties of the roll on the average or at various locations for which measurements are available, and so forth.

A tag such as an RFID tag can be associated with the roll in several ways. It can be present in the core of a roll, or on a portion of the material such as the leading or trailing edge, or it can be attached to a wrapping around the roll or attached to a box or other packaging material associated with the roll.

The information in the tag can be used to assist in routing of the roll. For example, the information can be read by an operator as an RFID scanner retrieves the ID c...
