Abstract: A work vehicle includes an assist motor that is located opposite an engine with respect to a continuously variable transmission device. The assist motor has an output shaft that extends coaxially with a drive shaft of the continuously variable transmission device and is interlocked with the drive shaft. A motor support platform that supports the assist motor protrudes more outward than the continuously variable transmission device does in a lateral direction relative to a vehicle body. The motor support platform includes a slide movement mechanism, and the slide movement mechanism is configured to change the position at which the assist motor is attached, relative to the continuously variable transmission device, axially of the drive shaft, between a connected position and a disconnected position of the drive shaft and the output shaft.

Abstract: Disclosed is a corrugated paperboard box making machine which comprises a feeding control mode setting unit for setting a feeding control mode to one of a first feeding control mode for controlling a sheet feeding apparatus and a second feeding control mode for controlling the sheet feeding apparatus such that the sheet feeding operation is performed plural times during the period of time in which the printing rotor is rotated 360 degrees, and a control apparatus for controlling the sheet feeding apparatus according to the set feeding control mode. The control apparatus is operable to execute a sheet feeding stop control processing of, when the second feeding control mode is set, controlling the sheet feeding apparatus such that the sheet feeding operation is stopped at least once after execution of the sheet feeding control processing.

Abstract: A torque upper limit value changing section increases an upper limit value of a torque instruction value in a powering range in case a rotational speed reduction degree is greater than a reference value and decreases the upper limit value of the torque instruction value in the powering range in case the rotational speed reduction degree is smaller than the reference value.

Abstract: Disclosed is a corrugated paperboard box making machine which comprises a sheet feeding apparatus, a processing apparatus, a folder-gluer, a counter-ejector for stacking the box-structured corrugated paperboard sheets and separating them as a batch, a speed setting unit for setting a sheet feeding speed, and a control apparatus. The control apparatus is operable to execute a sheet feeding control processing of the sheet feeding apparatus such that a sheet feeding operation of feeding one corrugated paperboard sheet is successively repeated a number of times corresponding to the number of the given number of box-structured corrugated paperboard sheets in the batch, and a sheet feeding stop control processing of, when the sheet feeding speed is greater than an allowable speed, the sheet feeding apparatus such that the sheet feeding operation is stopped at least once after execution of the sheet feeding control processing.

Abstract: A utility vehicle includes an electric motor for driving a propelling device, a battery for supplying electric power to the electric motor, a temperature sensor configured to detect a temperature of the battery, a discharge current setting unit for setting an upper limit discharge current value based on the detected temperature detected by the temperature sensor, and a control unit for regulating discharge current of the battery within the upper limit discharge current value determined by the discharge current setting unit and for controlling driving of the electric motor.

Abstract: A corrugated paperboard sheet feeding apparatus comprises: a plurality of sheet feeding rollers; a grate formed with a plurality of opening portions for receiving the sheet feeding rollers and configured to switch between contact and non-contact states of the corrugated paperboard sheet with respect to the sheet feeding rollers; and a suction box configured to suck the corrugated paperboard sheet downwardly by gaps between the sheet feeding rollers and the opening portions, wherein each of the gaps is formed to be 10 mm or less, and wherein the apparatus further comprises a mat switch for detecting an entry of a person into an area in a sheet feeding section, and a control device for stopping movement of the sheet feeding rollers and/or the grate when the mat switch is turned on.

Abstract: A torque upper limit value changing section increases an upper limit value of a torque instruction value in a powering range in case a rotational speed reduction degree is greater than a reference value and decreases the upper limit value of the torque instruction value in the powering range in case the rotational speed reduction degree is smaller than the reference value.

Abstract: A work vehicle includes a propelling device, which consists of a pair of right and left front wheels and a pair of right and left rear wheels, an engine configured to drive one of the pair of front wheels and the pair of rear wheels, an electric motor configured to drive the other of the pair of front wheels and the pair of rear wheels, a battery configured to supply electric power to the electric motor, and a controller configured to control the electric motor. The controller performs regeneration control at constant current value to charge the battery with regenerative power of the electric motor at a constant current value regardless of rotation speed of the electric motor.
