The invention relates to a motorized conveyor roller, comprising a roller body mounted so as to be able to rotate about a roller axle, a drive unit arranged inside the roller body and designed to generate a rotational movement about the roller axle between an axle element and the roller body. The invention is characterized by a control unit that is arranged inside the roller body and that is designed to receive a state signal from outside the roller body, to generate a control signal that describes a drive characteristic on the basis of the state signal, to control the drive unit by way of the control signal, to generate a self state signal that describes the state signal and/or the drive characteristic, and to transmit this self state signal outside the roller body.

A conveying unit for transporting goods on transport rollers in a transport plane. The transport rollers can be rotated about their respective axes of rotation with an adjustable rotational speed and adjustable direction of rotation. The axes of rotation of the transport rollers are adjustable by rotation about their respective pivot axes by a particular pivot axis angle, and at least two of the transport rollers can be adjusted differently from one another. There is also described a method for adjusting the conveyor unit.

The invention relates to a conveyor arrangement (1) for conveying a conveyed material, comprising a motor-driven conveyor roller (100), comprising a roller body (10) mounted so as to be able to rotate about a roller axis (A), a drive unit (20) arranged inside the roller body (10), coupled mechanically to the roller body (10) and an axle element (16) and designed to generate a torque between the axle element (16) and the roller body (10), a sensor function unit (40) arranged inside the roller body (10) and designed to sense a conveyed material to be conveyed by the motor-driven conveyor roller (100), and a control unit (30) that is connected to the sensor function unit (40) in order to transmit signals, wherein the control unit (30) is designed to receive a sensor signal from the sensor function unit and to transmit a control signal to the drive unit (20) depending on the sensor signal, wherein the control signal contains data for driving the motor-driven conveyor roller, in a conveyor mode, with a characteristic profile that is predefined by the control signal.

A support apparatus can comprise a cylindrical rod extending along a first rotation axis and comprising a first end portion provided with a first convex spherical segment and a second end portion provided with a second convex spherical segment. A first area can be configured to receive a portion of the first convex spherical segment. A second area can be configured to receive a portion of the second convex spherical segment. The cylindrical rod can be pivotable about a first pivot axis perpendicular to the first rotation axis. In some embodiments, methods of supporting an object can comprise engaging a surface of the object with the outer surface of the cylindrical rod wherein the first cylindrical rod supports a weight of the object while the first cylindrical rod is supported by the first fluid cushion and the second fluid cushion.

The application discloses a method for replacing seedbed culture substrate and a conveyor belt seedbed, the flatbed truck is used to receive the dropped culture substrate at the end of the conveyor belt that has been driven all the time, without manual removal by workers. The conveyor belt continues to drive until the flatbed truck is fully loaded or only when the culture substrate on the conveyor belt is emptied, only need to place the flatbed truck full of culture substrate at the head end of the conveyor belt when placing new culture substrate, and turn on the conveyor belt, which speeds up the efficiency of replacing the culture substrate, and this method only requires one person can complete the replacement of the culture substrate on the seedbed, which solves the technical problem that the existing method of replacing the culture substrate is to manually remove the culture substrate on the seedbed, which leads to the long time for replacing the culture substrate and low work efficiency.
