The invention provides a conveying device having a conveying performance higher than that of the related art, a sample analysis system and sample pretreatment device with the conveying device and a method for conveying a conveyance object. A conveying device 1 includes a permanent magnet 10 which is provided on a sample rack 111 side, magnetic poles 25 each of which includes a core 22 made of a second magnetic body and a winding 21 wound around an outer periphery of the core 22, drive circuits 50 each of which supplies a current to the winding 21 of the magnetic pole 25, and current command calculation units 55 each of which controls a value of the current to be supplied to the winding 21 from the drive circuit 50. The current command calculation unit 55 makes the currents to be supplied to the windings 21 vary.

A control apparatus includes a drive instruction value generator configured to generate a first drive instruction value that is greater than or equal to 0, which corresponds to torque in a first rotation direction, for driving a first motor that applies the torque in the first rotation direction to a shaft, and a second drive instruction value that is less than or equal to 0, which corresponds to torque in a second rotation direction, for driving a second motor, which is different from the first motor, that applies the torque in the second rotation direction, which is an opposite direction to the first rotation direction, to the shaft.

According to one aspect of the present invention, an accumulation module for a product delivery system includes an input shaft configured to receive an external drive force. A transfer shaft reverses an operation of the external drive force to define a reversing drive force. An output shaft receives the reversing drive force. An accumulation belt is operated by the reversing drive force. The accumulation belt operates in opposition to the external drive force.

An apparatus for loading live turkeys from a barn floor to cages on a transport trailer. A continuous motorized drive chain moves attached, solid sheets that are loaded with turkeys from the barn floor into the cage, and then back to the loading position. The drive chain is looped around first and second sprockets. Each rectangular sheet is rotationally connected at two of its corners to the drive chain forming a fixed end and a loose end. When the drive chain rounds the barn end, the loose end of the sheet slides upwards on a guide flap to keep the top of the sheet facing up. The sheets are driven forward to the cages, round the end at the cage end, pulled backwards from the cages toward the barn end, and then driven forward again, all without stopping the motion of the drive chain.

A controller for a drive motor (60) of a product conveyor belt at a checkout has a phase-start cutting and/or phase-end cutting controller (50) that controls the drive motor (60) in such a manner that the product conveyor belt is accelerated with reduced torque from a non-driven state. A start controller controls the drive motor (60) in such a manner that the drive motor (60) initially drives with a non-reduced torque when accelerating the product conveyor belt from the non-driven state before the phase-start cutting and/or phase-end cutting controller (50) further accelerates the product conveyor belt with reduced torque.
