An automatically tray feeding device includes: at least one conveying mechanism configured to convey a tray at different heights; at least one lifting mechanism configured to move the tray on a conveying mechanism at a first height to a conveying mechanism at a second height different from the first height; and a sorting table frame configured to carry the at least one conveying mechanism and the at least one lifting mechanism.

The present disclosure describes new systems and methods for influencing the rotational speed of a roller or other conveying systems and for controlling the speed, orientation or position of objects on a conveyor through the use of hydraulically amplified self-healing electrostatic (HASEL) actuators. HASEL actuators for such systems provide distinct benefits over traditional braking systems including: electrical control, eliminated need for an external source of pressurized air or fluid to allow use in certain environments, analog control of force or displacement in order to provide variable control of speed of objects on the conveyor system, and feedback to infer information about the state of the actuators as well as the state of objects being conveyed and/or state of the conveyor rollers.

A conveyor system is configured to prevent objects from getting caught or pinched between rollers and belts. The system includes a base, frames on opposite sides of the base, a plurality of rollers each having a bearing, an attachment axle, a drive shaft, a drive belt connecting the draft shaft to one of the bearings, and connecting belts connecting the bearings. The bearings may be disposed between the frames such that the drive belt and connecting belts are protected between the frames or may be disposed within the frames such that the drive belt and connecting belts are protected within the frame when a cover is attached to the frame.

A roller conveyor, comprising: a plurality of rollers (2) each of which has a cylindrical external surface (21), arranged to enable an object to be transported to rest; a motor (3); a transmission element (4), which kinematically connects the motor (3) to the rollers (2). The transmission element (4) is placed in contact with the external surface (21) of the rollers (2), or in contact with a portion of the rollers (2) which has the same diameter as the external surface (21), and in the same position as the contact point of the external surface with the element to be transported.

A powered stereo garage without cables on a parking space is disclosed, which includes a conveyor, a guide rail, a parking mechanism, a collector bush and a collector rail. The conveyor is arranged on the guide rail, and the parking mechanism is arranged at a periphery of the guide rail. The collector rail is arranged on the guide rail, the collector brush is provided on the conveyor, and the collector rail on the guide rail is electrically connected with the parking mechanism and the collector brush on the conveyor is electrically connected with a control box on the conveyor. The disclosure can supply power to the electric devices in the parking space according to parking or picking up demands, without laying a large number of cables in the garage to supply power to the electric devices in each of the parking spaces, and with improved fire safety.
