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.

The present invention concerns an order-picking system, comprising a goods-in buffer (3) with at least one storage area (4), in which the picked goods units are stored before they leave the order-picking system, and at least one staging area (6), in which the picked goods units are staged automatically by an operating device in accordance with a predetermined sequence. In addition, the present invention comprise a pallet racking warehouse for a shipping buffer and a stacker crane for a corresponding pallet racking warehouse. A gravity conveyor (5) for the staging area of the shipping buffer is also the subject-matter of the present invention.

A portable roller dislodging device is disclosed. The device is configured to dislodge a jammed roller of a conventional conveyor. The device may be detachably secured to the rail of the conveyor about any selectively-desired position. The device includes a motor, a rotating motor shaft, and a means for coupling the motor shaft to the jammed roller to facilitate dislodgement thereof. The device may be operated remotely via a wireless remote control device.
