Abstract
A system for decurling a web from a roll of material comprises rollers, a decurling station actuator, a sensor, and a controller. The rollers are configured to pull the web along a path with an angle. The decurling station actuator is configured to shift one of the rollers relative to the other rollers to adjust the angle of the path. The sensor is configured to sense a characteristic of the roll of material and generate sensor data. The controller is configured to receive a signal representative of the sensor data and direct the decurling station actuator to shift one of the rollers based at least in part on the sensor data.
Claims18
A system for decurling a web from a roll of material, the system comprising:
- a plurality of rollers configured to pull the web along a path with an angle, wherein the plurality of rollers comprise a pair of pull roller assemblies spaced apart from one another, each of the pair of pull roller assemblies including a pull roller and a pinch roller configured to pull the web from the roll of material;
- a decurling station actuator configured to shift at least one of the plurality of rollers relative to the other rollers to adjust the angle of the path, wherein the at least one of the plurality of rollers is a decurl roller positioned between the pair of pull roller assemblies, wherein each of the pair of pull roller assemblies further comprises—an arm pivotable toward the pull roller and configured to support the pinch roller, and a biasing element configured to bias the pinch roller toward the pull roller so that the pinch roller presses the web against the pull roller;
- a sensor configured to sense a characteristic of the roll of material and generate sensor data;
- and
- a controller configured to receive a signal representative of the sensor data and direct the decurling station actuator to shift the decurl roller based at least in part on the sensor data.
A method of decurling a web from a roll of material, the method comprising:
- pulling a portion of the web, via a plurality of rollers, along a path forming an angle, wherein the plurality of rollers comprise a pair of pull roller assemblies spaced apart from one another, each of the pair of pull roller assemblies including a pull roller and a pinch roller configured to pull the web from the roll of material;
- sensing, via a sensor, a characteristic of the roll of material to generate sensor data;
- and
- directing, via a control system, a decurling station actuator to shift at least one of the rollers to adjust the angle of the path based at least in part on the sensor data, wherein the at least one of the plurality of rollers is a decurl roller positioned between the pair of pull roller assemblies, wherein each of the pair of pull roller assemblies further comprises—an arm pivotable toward the pull roller and configured to support the pinch roller, and a biasing element configured to bias the pinch roller toward the pull roller so that the pinch roller presses the web against the pull roller.
A system for decurling a web from a roll of paper material, the system comprising:
- a decurling station frame including—
- a pair of rails that support the roll of paper material, and
- support walls extending vertically from the pair of rails;
- a pair of pull roller assemblies horizontally spaced apart from one another on the support walls, each of the pair of pull roller assemblies including—
- a rotatable pull roller,
- a rotatable pinch roller positioned proximate to the pull roller so that the pinch roller presses the web into the pull roller, and
- an actuator configured to rotate the pull roller;
- a rotatable decurl roller supported by the support walls and positioned between the pair of pull roller assemblies;
- a decurling station actuator supported by the support walls and configured to vertically shift the decurl roller;
- a sensor configured to sense a characteristic of the roll of paper material and generate sensor data;
- and
- a controller configured to receive a signal representative of the sensor data and direct the decurling station actuator to vertically shift the decurl roller based at least in part on the sensor data.
