An apparatus for the preparation of comestible-containing sandwich products comprises a sandwich product assembly station and corresponding means for the fabrication and assembly of a sandwich product in the vertical direction. The apparatus includes an extruder nozzle, wafer trays and corresponding components for the location of wafers on opposite sides of the extruded product, an indexing wheel for receiving the assembled sandwich product, and sandwich transporting means for moving the sandwich to a wrapping assembly and from there to a discharge end, wherein all of the components of the apparatus are mounted in cantilevered fashion on a vertical support or base member. Each element is powered individually by a servo motor or actuator and controlled by a controller allowing the variability of throughput for each station.

An image forming apparatus includes a sheet accommodation unit, a feed roller to feed a sheet along a conveyance path, a first encoder to detect rotation of the feed roller, a conveying roller downstream of the feed roller, a second encoder to detect rotation of the conveying roller, and a motor to drive the feed roller and the conveying roller. A first clutch switches between connecting and disconnecting the paper feed roller to the motor. A second clutch switches between connecting and disconnecting the motor to the conveying roller. A first sensor detects the sheet at a first position. A second sensor detects the sheet at a second position. A control unit controls the motor based on output from the first encoder when the sheet is at the first position and output from the second encoder when the sheet is at the second position.

A first shaft control section is configured to control rotation of a first support shaft supporting a first roll such that a sheet is unwound from the first roll at a predetermined running speed. A second shaft control section is configured to execute a first rotation control of regulating a rotational speed of a second support shaft supporting a second roll such that a peripheral speed of the second roll coincides with the predetermined running speed of the sheet of the first roll. The second shaft control section is configured to regulate the rotational speed of the second support shaft by acceleration or deceleration such that an adhesive on an outer peripheral surface of the second roll arrives at a pressing position when a target joining portion of the sheet of the first roll meets the pressing position.

In steady control, a shaft control unit (922) adjusts rotation speed of a first support shaft (31) to cause a first roll (R1) to have peripheral speed equal to predetermined conveyance speed by maintaining a sheet storage amount in a storage mechanism (5) in a first storage amount as a reference. In storage amount adjustment control, the shaft control unit (922) accelerates the rotation speed of the first support shaft (31) to increase the peripheral speed of the first roll (R1) higher than the conveyance speed, until the sheet storage amount in the storage mechanism (5) reaches a predetermined second storage amount that is larger than the first storage amount. A calculation unit (911) calculates an outer diameter of the first roll (R1) based on the conveyance speed when the steady control is performed, and calculates the outer diameter of the first roll (R1) based on the sheet thickness calculated from a decrease amount of the outer diameter of the first roll (R1) in the steady control when the storage amount adjustment control is performed.

A motor controlling system is disclosed. The motor controlling system is integrated in an apparatus having roll-to-roll mechanism, and comprises a linear light source, N number of cameras and a modular electronic device. When a roll of continuous web material is discharged by an unwinding unit of the roll-to-roll mechanism so as to be further transferred to an inspection unit, the cameras are controlled by the modular electronic device to capture a plurality of time-consecutive material image frames. Subsequently, the modular electronic device conducts a defection inspection for a segment of the continuous web material by applying an image process to the material image frames. As a result, in case of there being at least one defect found, the modular electronic device stops a plurality of motors of the apparatus from running, thereby making the segment of the continuous web material be positioned on an inspection platform.

A sheet transport apparatus includes a first direction changing roller arranged along a transport path, wherein a sheet is transported along the transport path; a second direction changing roller disposed on the transport path, wherein the first direction changing roller and the second direction changing roller are next to each other in a direction perpendicular to the transport path, and the first direction changing roller and the second direction changing roller change an orientation of the sheet from a first orientation to a second orientation; and a control circuit configured to control one of the first direction changing roller and the second direction changing roller so that the first direction changing roller rotates slower than the second direction changing roller so as to change the orientation of the sheet from the first orientation to the second orientation.

A control device of a transport device includes a control unit configured to control a roll motor for rotating a first rotary shaft on which a medium is held and a transport motor for rotating a first driving roller, a tension detection unit configured to derive, for each tension detection cycle, a detected tension value of a tension applied to a tension adjustment portion of the medium, and a tension F/B unit configured to calculate a tension F/B correction amount by feedback control based on a deviation between a target tension and the detected tension value. The control unit is configured to calculate a driving force by the roll motor based on the tension F/B correction amount, and control the roll motor based on the driving force.
