  7. A use of a discharge device (20) or a conveyor system (1) according to one of the preceding claims for transferring goods (9) to be conveyed at the transfer point (26a) in order to at least intermittently convey the goods (9) to be conveyed in the conveying direction (FR) and to selectively discharge the goods (9) to be conveyed into the discharge region (3), which is arranged laterally to the conveying direction (FR) in a top view.
  8. The use according to the preceding claim, wherein the smallest possible goods (9) to be conveyed are dimensioned in such a way that they always rest on two conveyor belts (24) of two adjacent belt slides (21) in a conveyor region (26f).
  9. The use according to one of the two preceding claims, wherein the smallest possible goods (9) to be conveyed are dimensioned in such a way that a smallest side length (B9) amounts to no more than 120 mm, particularly no more than 90 mm, in a top view.

Description

The invention relates to an ejection device. The WO 2020/025329 A1 This reveals a cross-belt sorter configured as a horizontal sorter. The cross-belt sorter comprises multiple carriages arranged in a single direction of travel. Each carriage includes a cross-belt onto which the conveyed material can be placed. The cross-belt is movable in a transverse direction, perpendicular to the direction of travel. To sort the conveyed material, the cross-belt is driven in a controlled manner, accelerating the material laterally (in the conveying direction) and pushing it off the carriage (ejection). Such a cross-belt sorter is characterized by its ability to precisely eject the conveyed material, even at high conveying speeds. These types of cross-belt sorters are large installations requiring a floor space of over 100 square meters. To introduce the conveyed material onto the crossbelt sorter (feeding), a side-mounted infeed is usually used, which guides the material towards the sorter at an acute angle relative to its conveying direction. Alternatively, toploaders can be used, which drop the material onto the conveyor carriage from above. The DE 20 2012 04 830 U1 This diagram reveals a transverse belt sorter configured as a vertical sorter. The return of the conveyor carriages occurs vertically below a conveying level for the conveyed goods. All goods fed onto the vertical sorter must be diverted laterally before reaching the rear or collected at the end in a receiving station. Due to the vertical deflection, unlike a horizontal sorter, it is not possible to return the conveyed goods to a starting point in a closed loop. The conveyor carriages of a vertical sorter are similar in size to those of a horizontal sorter and require large deflection radii. The conveyor carriages of the cross-belt sorter are dimensioned to accommodate the entire conveyed item. A typical length in the conveying direction is therefore approximately 50 to 100 cm. Due to the size of the conveyor carriages and the resulting turning radius, installing a cross-belt sorter requires a considerable amount of space. Furthermore, access to the cross-belt sorter must be secured with extensive fencing to prevent the risk of injury from the moving conveyor carriage. To divert conveyed goods during a modular belt conveyor or roller conveyor, it is not necessary to provide a high-priced crossbelt sorter. The solutions available on the market under the names "Interroll High Performance Divert 8711" and "Interroll Transfer RM 8731" are suitable for this purpose, enabling the implementation of one or more diverting stations downstream of a belt or roller conveyor, or even between several such conveyors. In the "Interroll Transfer RM 8731", the conveyed material is completely decelerated during discharge in the conveying direction, in order to then be accelerated in a discharge direction perpendicular to the conveying direction. Both the "Interroll Transfer RM 8731" and the "Interroll High Performance Divert 8711" can only be operated at a conveying speed that is significantly lower than the conveying speed of the crossbelt sorter. The aforementioned solutions can be used modularly in a roller conveyor or a belt conveyor. The advantage of such diverting units compared to a cross-belt sorter is, in particular, that the conveyed goods can be introduced onto the diverting unit at the conveyor level. Furthermore, another roller conveyor or belt conveyor can be arranged directly downstream of the compact diverting unit in the conveying direction, allowing any goods that have not been diverted to be easily transported to the next station. The US 2015/360869 A1 The issuing authority considers this to be the closest prior art. It describes a conveyor sorting system comprising a frame and two or more carriages traveling along the frame in one direction. Each carriage includes a belt oriented in one direction perpendicular to the carriage's direction of travel and an electric motor configured to drive the belt. The belt has a width of no more than 8 inches. The EP 1 153 860 A1 The invention describes a conveying device comprising a main conveying section formed by connecting a plurality of conveying subunits, and a drive device for driving the main conveying section. Each of the conveying or subunits has a secondary conveying section, a drive device for the secondary conveying section for driving the secondary conveying section forwards and backwards, and a device for communicating with a control command device. A conveying direction of each of the secondary conveying sections is orthogonal to a conveying direction of the main conveying section. It is an object of the present invention to provide an improved discharge device that is particularly flexible in combination with other The discharge device can be used in conveyor lines. It is designed to have a performance comparable to cross-belt sorters, but requires significantly less installation space and effort, and is
