Abstract: A driverless transportation vehicle for piece goods has a chassis, a traction drive, a load-transfer device with a load-transfer drive, and a control system. The chassis has at least two wheels arranged on an axle and the traction drive is configured to drive the wheels. The load-transfer device picks up an item of piece goods and transfer its center of mass on the vehicle. The control system controls the traction drive to prevent the transportation vehicle from tilting about the axle of the chassis, while the driverless transportation vehicle balances on only the at least two wheels. The control system additionally actuates the load-transfer drive in such a way that the position of the center of mass of the cargo is adapted for a driving maneuver that is to be carried out.

Abstract: An apparatus for taking hold of and releasing an object, which may be surrounded by a packaging with no surface stiffness and/or be positionally unstable in some circumstances. The apparatus includes: a manually and/or machine-controlled arm which can be actively directed to the object; a suction opening arranged at the freely moving end of the arm; a suction device for providing a negative pressure required at the suction opening; and a controllable vacuum check valve at the suction opening for adjusting the negative pressure acting on the object. The device makes it possible, using suction, to securely take hold of and then correspondingly further transport objects that are difficult due to their surface properties, e.g., items to be sorted with an inhomogeneous shape and/or a porous surface and/or items to be sorted that are packed, for instance, in plastic bags.

Abstract: A sorting system and a method for sorting piece goods provide for conveying the piece goods to be sorted on a delivery level to a delivery point and delivering them there into or onto a receiving device moving on a collection level receiving the piece goods. The collection level is disposed below the delivery level. The receiving device travels over an individually determined route on the collection level.

Abstract: An apparatus and a method convey and sort articles. The apparatus contains a link conveyor, having link elements, pushing-off elements, drive elements, and a control device. The link conveyor runs along a belt-movement line and has along the belt-movement line the link elements which are arranged to follow one after the other and form a conveying surface for the articles. In each case one pushing-off element can be arranged on one of the link elements, above the conveying surface, and therefore the pushing-off element runs along the belt-movement line together with the link element, and the pushing-off element can be moved, and stopped, along a pushing-off-line, which is arranged transversely to the belt-movement line. The drive elements each drive one or more pushing-off elements individually, and therefore the operations of moving and stopping these pushing-off elements, which are arranged to follow one after the other, are independent of one another.

Abstract: A driverless transport vehicle, a conveying system, and a method for transporting piece goods. The driverless transport vehicle overcomes a climbing section equipped with a primary side of an energy transmission device. The driverless transport vehicle, which can be moved individually and autonomously on a conveying plane, has a secondary side for energy pick-up in order, assisted by the energy pick-up, to overcome a height difference of the climbing section and/or a transition between the conveying plane and the climbing section. The formation of a connection between the primary side and the secondary side and the overcoming of the climbing section and of the transition between the conveying plane and the climbing section take place at a throughput speed without a slowing-down.

Abstract: A method ejects an item of piece goods from a load-supporting system which can be driven individually and in a driverless, automated manner on a surface. The method includes carrying out individual and driverless, automated transport of the goods on the load-supporting system and ejecting the item of piece goods downwards through an ejection region situated in a bottom region of the load-supporting device.

Abstract: An apparatus for handling articles in a transporting unit, which may be an interchangeable container, having a mobile conveying unit that is moved into the transporting unit to unload the unit, collect and receive articles stacked in the unit under the control of an operator, and convey the articles out of the transporting unit in an unloading direction for further processing. The apparatus generally facilitates removal from the transporting unit with a small amount of effort during the unloading of non-uniformly or randomly stacked articles. The conveying unit has a floor conveyor which conveys in a loose random arrangement the articles that have been toppled or removed from the stack of articles.

Abstract: A device for handling objects includes an unloading head, onto which the objects can be transported and from which the objects can be unloaded by an operator. A lifting apparatus is connected to the unloading head. The height of the unloading head can be adjusted by way of the lifting apparatus and a sensing apparatus that can be activated and the height of the unloading head can be adjusted. In order to achieve a throughput increase in the handling of objects, the sensing apparatus is arranged in such a way that the sensing apparatus can be triggered by the operator by way of an object that is located on the unloading head.

Abstract: A vehicle charging station charges an energy accumulator in a battery-driven vehicle, namely an electric bus or hybrid vehicle, the vehicle being parked in a pre-defined parking position during the charging process. The charging station contains a base which is arranged in the vicinity of the pre-defined parking position and an articulated arm. One end of which is mounted in a revolute joint on the base and is rotary driven by a rotary drive and the other end is connected to a supply-contact device by a second revolute joint, such that the supply-contact device can be moved, by a pivoting movement of the articulated arm, between an idle position, in which the supply-contact device is positioned above the vehicle roof, and a working position, in which, for charging purposes, electrical contact is made between the supply-contact device and a receiving-contact device arranged in a static manner on the vehicle roof.

The radiation-curable coating compositions comprise at least one urethane(meth)acrylate (A) having a molar mass Mn of 100 to 500 g/mol and two ethylenically unsaturated double bonds per molecular and at least one monoethtlyenically unsaturated reactive diluent (B) which contains at least one cycloaliphatic or heterocyclic group.

Abstract: An apparatus and a method transport articles by way of a plurality of parallel buffer sections. A feeding device transports the articles to a buffer device at a predetermined feeding speed. Each article is then directed into in each case one buffer section, which is either in a feeding mode or in a transporting-away mode. Each buffer section transports the articles which have been directed into this buffer section to a transporting-away device. In the feeding mode, the buffer section transports to the transporting-away device at a feeding buffer speed which depends on the feeding speed. In the transporting-away mode, the buffer section transports to the transporting-away device at a transporting-away buffer speed which depends on the transporting-away speed. The transporting-away device transports the articles away at a predetermined transporting-away speed.

Abstract: An apparatus and a method stand up and process articles of different dimensions, in particular flat mail items. A conveying device transports articles to an up-ending apparatus. The up-ending apparatus transports the articles further and, in the process, up-ends the articles such that the up-ended articles stand on an edge. Up-ended articles are transported to a separating apparatus. The separating apparatus separates flat articles such that a stream of upright, spaced-apart articles leaves the separating apparatus. Up-ended and separated articles are transported to a format-separating device. The format-separating device divides the articles as a function of the dimensions thereof into article classes such that all of the articles of a set of articles belong to the same format class. All of the articles of a set of articles are transported as a stream of upright and spaced-apart articles to an appropriate processing device. The processing device processes the articles.
