Abstract

In order to enable roll adapters (61) on a suspended conveyor device (10) to be removed easily, the roll adapter (61) to be removed is pivoted about a pivot axis relative to the running track (809) from a usage orientation, in which a vertical axis of the roll adapter (61) encloses an angle of between 60° and 120°, preferably 90°, with the running track (809), to a removal orientation, in which the vertical axis of the roll adapter (61) extends between the running track (809) and the conductor track (807). During the pivoting movement of the roller adapter (61) from the usage orientation into the removal orientation, an electric contact between the current collector unit (610) and the conductor track (807) is interrupted. After the roll adapter (61) to be removed has been pivoted into the removal orientation and after the electric contact has been interrupted, the roll adapter is removed via an access region (805) by way of a sideways movement, transverse to the direction of travel, of the roll adapter (61) to be removed.

Description

REMOVING A ROLL ADAPTER FROM A RAIL NETWORK OF A HANGER BAG STORAGE The invention relates to a method for removing one of several roller adapters that can be moved along a suspended conveyor device in a direction of travel for transporting hanging bags that are designed to hold stored goods, wherein the suspended conveyor device comprises a rail network with a track and a power supply system with an electrical conductor track, which conductor track runs at a distance (and preferably parallel) to the track, the roller adapters each comprise a height axis, a drive device with a driven wheel and a power supply with a current collector unit, which power supply for driving the driven wheel is connected to the drive device, and the roller adapters each roll over the driven wheel on the track of the rail network and are electrically contacted with the conductor track via the current collector unit. Furthermore, the invention relates to a suspension conveyor device comprising a rail network with a track, an energy supply system with an electrical conductor track, which conductor track runs at a distance (and preferably parallel) to the track, Hanging bags for storing goods, and Rolling adapters for transporting the hanging bags, wherein the rolling adapters are movable in a direction of travel along the hanging conveyor device, which rolling adapters each have a length measured in the direction of travel, a height axis running orthogonal to the direction of travel, a drive device with a driven wheel and a power supply with a current collector unit, which power supply is connected to the drive device, and which rolling adapters each roll over the driven wheel on the track of the rail network and can be electrically contacted with the conductor track via the current collector unit. In addition, the invention relates to a storage system for picking stored goods, comprising a loading station for loading hanging bags with stored goods, a storage area for storing hanging bags with stored goods, a packing station for unloading the hanging bags and packing the cargo into shipping packages, and an overhead conveyor device connecting the loading station, the storage area and the packing station, and/or an overhead conveyor device arranged in the storage area. The invention also relates to a method for carrying out maintenance work on a hanging bag warehouse with hanging bags that can be moved on a network by means of rolling adapters or that can be moved autonomously or at least partially autonomously by means of the rolling adapters for receiving stored goods, a rolling adapter according to the method, a hanging bag warehouse and a storage arrangement. In automated warehouses, production sites and when transporting goods, such as in mail order, it is necessary to load stored goods into and unload them from containers as automatically as possible. The goods can be stored in these containers before they are delivered and then taken to a packing station where they are packaged for further transport to the customer. Transport within the storage system is usually carried out using overhead conveyors. The containers are usually hanging bags that are made like fabric bags and are suspended from a rail system at the top with a type of wire hanger. A container of this type is known from WO 2014/012965 A1, for example. Its side wall elements, which are connected to one another via a connecting area, are controlled via a rod so that the side wall elements can be folded open. In the area of a loading station, the containers are also transferred to a horizontal or inclined position. Comparable goods containers and associated overhead conveyor devices are known, for example, from DE 102004018 569 A1, EP 2 130 968 A1 or EP 2 196 415 A. The hanging pockets described therein consist of flexible materials in the form of a loop in which the stored goods are held. For loading, these hanging pockets are opened from above in order to be able to place the stored goods in the loop. Unloading takes place by either removing the stored goods from the side or ejecting them, or, for example, according to EP 2 130 968 A1, by opening the loop downwards. Furthermore, a goods container is known from DE 103 54419 A1 which has a relatively rigid and flat plastic wall with a cutout for loading and unloading with stored goods. Other containers for conveying goods are made like hanging flat plastic trays, which are covered on one side with elastic materials, which clamps the stored goods. It is known to load such containers for conveying goods mechanically and to unload them manually. A transport cycle is based on the slowest process, which also depends on the amount of goods being transported. In particular, a large number of individual goods can slow down loading and/or unloading. For example, the unloading and/or assembling of disassembled containers for conveying goods can determine the maximum possible transport cycle. EP 2 686 258 B1 relates to a suspen
