Abstract: A method for picking objects is specified, in which at least one object is removed from a source loading aid and placed into a target loading aid using a robot. After the operation of removing the object, a first sensor system of the robot is used to check whether at least one object is held by the robot. A number and/or a type of the at least one removed object is ascertained using the second sensor system. The operation of placing the at least one object into the target loading aid is aborted or modified if no object is held by the robot or the number and/or the type of the at least one removed object does not contribute to completing the picking order, which defines a desired number and/or desired type of objects in the target loading aid. Furthermore, a device and a computer program product for performing the presented method is specified.

Abstract: In a method and arrangement for distributing articles, an order management system acquires an order for delivering articles, the articles to be delivered are transferred from an article store and the articles included in an order are order-picked into at least one mobile shelf unit shelf compartment. The mobile shelf unit is subsequently transported to a dispensing station including a first article storage region separated by a first separating wall and a customer access region and is brought into a handover position, in which the at least one shelf compartment is accessible via a closeable opening in the first separating wall. When an article dispensing system accepts a request for taking over the articles by a person or a machine associated therewith, it releases the closeable opening if authorization exists for taking over the articles. Alternatively a loading robot can load the articles to be delivered into the machine.

Abstract: A method for storing piece goods of different dimensions in storage channels conveys the goods to the channels using a piece goods receiving device movable along the channels in an x direction and into the channels using a transport device extendible into the channels in a z direction. The goods are stored tightly-packed in the channels. A width dimension of the goods is detected and the goods are assigned to the different width classes. The goods are supplied to a pick-up station selectively according to width classes using a conveying system, then transferred to the receiving device, and using the transport device a group of goods is moved from the receiving device into the channel simultaneously in a storage direction and in a depth direction of the channel so that a lateral wall of the rearmost good in the storage direction is substantially flush with the channel end edge.

Abstract: The invention relates to a method for bundling conveyed streams on a material handling element (Ka . . . Kz, K1 . . . K34) comprising a number of incoming conveyor segments (1a, 1b), at least one coupling (2) to an outgoing conveyor segment (3), on which the incoming conveyor segments (1a, 1b) converge, and a number of holding devices (4a, 4b) for holding a conveyed stream on the incoming conveyor segments (1a, 1b). In a first step the conveyed objects (17) are vectorially combined in in ascending/descending order according to a desired sorting sequence. When a conveyed object (17) passes the material handling element (Ka . . . Kz, K1 . . . K34) a vector corresponding to the actual sequence is entered in the vector combination. Conveyed objects (17) are released if a ring with a constant direction is avoided in the vector combination. The invention further relates to a material handling element (Ka . . . Kz, K1 . . . K34) for carrying out said method.

In a first step of the method, target arrival times (TA1 . . . TA3, TB1, TC1 . . .

A conveyed object (17) is released at a release time which substantially corresponds to the target arrival time (TA1 . . . TA3, TB1, TC1 . . . TC3) minus the target pass-through time (t1, t2, t6) required for the conveyed object (17) to be transported as planned from a current position to the destination (23a . . . 23c). The invention further relates to a materials handling element (Ka . .

Abstract: The invention relates to a method and a system intended for delivering items (4) in delivery containers (3) and in which, in a supply depot (1), the items are order picked, in accordance with orders placed, into delivery containers and then the delivery containers are loaded onto a transport rack (12). The transport rack is loaded with the delivery containers in a loading sequence determined by the computer system (2). Thereafter, the transport racks are transported, by means of a transport system, from the supply depot to a buffer depot (collection depot). A consignee (68) can collect the ordered item from the buffer depot at an issuing station (56). The transport rack is positioned, in the buffer depot, against a docking apparatus (54) such that a storage and retrieval unit (17) can access compartments in the transport rack.
