A packaging machine may include a foil transport device and a controlling system for controlling an operation of at least one drive unit of the foil transport device. The controlling system is designed to activate the drive unit during a production run of the packaging machine on the basis of a speed- and/or temperature-dependent friction moment characteristic curve detected by means of a rotationally driven measurement run carried out by the drive unit. The disclosure furthermore relates to a method for controlling a drive unit of a foil transport device.

A medium transport device includes a feeding roller that feeds a recording medium, a transport roller that transports the recording medium toward a recording head, and a transport motor which is a common driving source for the feeding roller and the transport roller. The medium transport device includes a power transmission mechanism that transmits power of the transport motor to the feeding roller, and a control section that controls a current of the transport motor. The control section measures a current value flowing through the transport motor during driving as a measured current value, and adds a predetermined offset value to the measured current value to set a second limit value as a limit value of the current supplied to the transport motor.

A sheet processing apparatus is configured to press a fold line that is formed on a sheet. The sheet processing apparatus includes: a sheet supporting unit configured to support the sheet in a pressing direction for pressing the fold line; a pressing unit configured to press the fold line that is formed on the sheet that is supported by the sheet supporting unit; and a pressing-force generating unit configured to generate a pressing force for pressing the sheet supporting unit against the pressing unit at a central part in a direction along which the fold line is formed.

A motor driver drives a motor that controls a position of an object based on a command from a controller. The motor driver includes: a correction command output part that outputs a correction command for correcting a position of the motor based on a position of the object detected by a displacement sensor that detects the position of the object; and a position controller that outputs a drive signal for driving the motor based on the command from the controller and the position of the motor detected by an encoder that detects the position of the motor, or based on the correction command and the position of the motor detected by the encoder.

According to an example, to eject print media from an image forming apparatus, a variable page feed velocity of a first page of print media exiting a feed zone is detected. An acceleration value and a deceleration value based on the variable page feed velocity of the first page is calculated. The calculated acceleration is applied to a media movement component in the output zone when the entire first page has cleared a media sensor in the front of the output zone, and the deceleration is applied when the tail end of the first page is in a brake zone. In some examples, a second page of print media and a variable page feed velocity of the second page exiting the feed zone is detected, and the media movement component in the output zone is accelerated to match the variable page feed velocity of the second page.

A sheet alignment device includes a driven roller, a drive roller, a displacement driving device, an information acquisition portion, and a displacement control portion. The drive roller is configured to rotate in a first rotation direction and in contact with an upper surface of each of sheets conveyed onto a tilt tray, to feed the sheets toward a base end portion of the tilt tray. The drive roller is configured to rotate in a second rotation direction and in contact with an uppermost surface of the sheets, to discharge the sheets from the tilt tray. The displacement control portion is configured to, when the drive roller rotates in the first rotation direction, control a holding position of the drive roller in accordance with the number of the sheets on the tilt tray and thickness information of each of the sheets acquired by the information acquisition portion.

The present invention is directed to a method of loading workpieces using a piler conveyor P including a first conveyor which sequentially conveys the workpieces by continuous operation at a first speed, a second conveyor which magnetically attracts, on a lower surface, the workpieces passed from the first conveyor for sequential conveyance by intermittent operation, and a loading frame where the workpieces are placed, the method including a first step S1 of gradually accelerating the second conveyor to the second speed, a second step S2 of operating the second conveyor at the second speed and passing the workpieces 1 from the first conveyor to the second conveyor, a third step S3 of gradually decelerating the second conveyor from the second speed for operation, and a fourth step S4 of stopping the second conveyor and causing the second conveyor to lose a magnetic force and dropping a workpiece 1 positioned above the loading frame onto the loading frame 30, wherein the first speed and the second speed are set at an equal constant speed.

A stacking apparatus for value documents, having a stack deposit device and a braking device which is arranged along the transport path of the value documents immediately before the stack deposit device. On the transport shaft of the braking device at least one driving roller is firmly mounted and at least one roller rotatably supported on the transport shaft. At least one cam roller is firmly mounted on a braking shaft of the braking device and at least one eccentric roller. By a rotation of the braking shaft, the eccentric roller can electively be brought in engagement with the opposing driving roller so that a value document becomes clamped between these, or be brought out of engagement with the opposing driving roller, so that the value document is no longer clamped between these, but rather is brakable by the engagement between the cam roller and the rotatably supported roller.

A meandering correction apparatus includes a transport mechanism, an orientation measurement part, a Young's modulus calculation part, a meandering prediction part and a meandering correction part. The transport mechanism transports an elongated strip-shaped base material in a longitudinal direction thereof along a transport path. The orientation measurement part measures fiber orientations of the base material in respective measurement regions on the transport path, the measurement regions being different in widthwise position from each other. The Young's modulus calculation part calculates Young's moduli of the base material for the respective measurement regions, based on the fiber orientations. The meandering prediction part predicts subsequent meandering of the base material, based on the Young's moduli, to output meandering prediction information. The meandering correction part corrects the widthwise position of the base material, based on the meandering prediction information. The meandering correction is made based on the fiber orientations of the base material. Thus, the widthwise position of the base material is corrected without depending on only edge sensors.

A medium wind-up apparatus includes a reel-out motor, which is a driving source that winds up a medium, a control portion that controls the reel-out motor on the basis of a torque limit value, which regulates an upper limit of an output torque of the reel-out motor, and a reel-out side detection portion that detects a rotation speed of the reel-out motor, in which the control portion changes the torque limit value on the basis of the detected rotation speed. In this case, it is preferable that the control portion increase the torque limit value in a case in which the detected rotation speed falls below a first threshold value, and that the control portion reduce the torque limit value in a case in which the detected rotation speed exceeds a second threshold value, which is larger than the first threshold value.
