ACCUMULATION DEVICE
An accumulation device is provided with a loading unit, a tensioning unit, an accumulation unit, and unloading unit and a controller. The tensioning unit comprises multiple fixed rollers capable of rolling, and movable rollers capable of rolling and arranged so as to be capable of moving with respect to the fixed rollers. Substrates are conveyed so as to move back and forth alternately between the fixed rollers and the movable rollers in a wrapped state, and a prescribed tensile force is applied to the substrates by a force acting on the moveable rollers in the direction away from the fixed rollers. The controller performs control so as to maintain the positions of the movable rollers in the tensioning unit constant.
Motor controller, sheet conveying device, and image forming apparatus
A motor controller (58) according to the present invention includes a pulse width detection portion (595), a speed control portion (591), a pulse width storage portion (596), a same pulse detection portion (597), and a stop processing portion (598). The pulse width detection portion detects the pulse widths of pulses included in the pulse signal. The speed control portion performs: an acceleration control of the drive motor; and a deceleration control of the drive motor. The same pulse detection portion detects, from among the pulses included in the pulse signal inputted during the deceleration control, a pulse in which the pulse width detected by the pulse width detection portion is the same pulse width as the pulse width of an earliest pulse stored in the pulse width storage portion. The stop processing portion stops control of a rotation speed of the drive motor performed by the speed control portion.

PAPER FEEDING APPARATUS
In a paper feeding apparatus, paper feed rolls in paper feed roll rows for feeding the lowermost one of cardboard sheets placed in a stacked manner on a paper feeding table intermittently one by one toward the printing device are coupled via shafts to separate servomotors. The servomotors are controlled so to be accelerated synchronously and rapidly from a stopped state to a high rotational speed during one cycle of feeding through contact with the lowermost cardboard sheet, while controlled so to be decelerated from the high rotational speed to be stopped rapidly and respectively when determined not to be in contact with the lowermost cardboard sheet.
System for high speed feeding a thin sheet metal strip into a reciprocating press
A sheet metal strip is directed from a supply coil into a unitized system including a frame supporting a feed roll driven by a variable speed motor. The strip is directed upwardly from the feed roll between vertical guide rods to produce an inverted U-shaped vertical loop detected by sensors connected to control the feed roll motor. A servo driven index roll receives and advances the strip into tooling within a reciprocating press. Vibration insulators support the frame from a base stand mounted on air casters which provide for quickly removing the system from the press. The axial length of each roll is less than the width of the strip and engages only a center portion of the strip. A second index roll driven by a servo motor may be used on the press to provide push/pull advancement of the strip through the press.
Method and system for a robotic tape applicator
A system comprising: a source of a tape comprising a material associated with an adhesive and at least one removable liner; an applicator head; a cutting mechanism; at least one drive feeding mechanism configured to index the tape from the source to the applicator head at a controlled rate; wherein the applicator head is controllable to apply the material on a surface or a substrate; and wherein the applicator head comprises a cutting mechanism configured to sever the material while leaving the at least one removable liner intact.
SHEET SUPPLYING APPARATUS AND SUPPLYING METHOD FOR SHEET THEREBY
Described herein is a sheet supply apparatus for continuously supplying sheets while splicing the leading edge of the sheet of a standby roll to the trailing end of a sheet being unwound from a working roll by using an auto splicer, the sheet supply apparatus including: a turret unwinder provided with fixation chucks that each fix both ends of a paper tube, and configured to switch the positions of the standby and working rolls; a detector configured to detect the position of one of both axial ends of the standby roll; a corrector configured to be connected to each of the fixation chucks and to correct the position of the standby roll; and a controller configured to align an end of the standby roll so that the end of the standby roll is aligned with the end of the working roll while correcting the position of the standby roll.
Automatic cut and transfer coiler and or spooler
An automatic cut and transfer coiler and spooler apparatus, system, and method for use generally comprising a rotatable turret with two independently driven spindles thereon wherein the drives for the independent spindles are attached to the turret for selectively rotating the spindles about their own axis independently.
