Shuttle system and method for operating shuttle system by means of a control device

A method for operating a shuttle system by a control device, wherein the shuttle system comprises a rack with a driveway and a multi-deep storage channel with at least two storage locations, wherein the shuttle system further comprises at least two shuttles, wherein the at least two shuttles are arranged to store, retrieve, or transfer conveyed goods, wherein the at least two shuttles receive orders for storing, retrieving, or transferring a conveyed good from the control device, wherein, to prevent a blockage situation and/or to increase a storage density, the method comprising:

• a shuttle receives, via the control device, an order for storing a conveyed good, wherein the order specifies the storage channel to be approached, but not the storage location;
• the shuttle enters the storage channel and subsequently moves within the storage channel;
• during the subsequent movement, a sensor checks whether the storage locations located in front of the shuttle are free or occupied;
• if the sensor detects an occupied storage location, the conveyed good is stored in the free storage location directly adjacent to the occupied storage location;
• and
• if the sensor does not detect an occupied storage location, the conveyed good is stored in the last storage location in an entry direction within the storage channel in case of a storage channel designed as a dead end;
• in the case of a storage channel with two channel entrances, the conveyed good is stored in a storage location located in a middle of the storage location or in the last storage location in entry direction.

A method for operating a shuttle system by a control device, wherein the shuttle system comprises a rack with a driveway and a multi-deep storage channel with at least two storage locations, wherein the shuttle system further comprises at least two shuttles, wherein the at least two shuttles are arranged to store, retrieve, or transfer conveyed goods, wherein the at least two shuttles receive orders for storing, retrieving, or transferring a conveyed good from the control device, wherein, to prevent a blockage situation and/or to increase a storage density, the method comprising:

• a1. if at least two active or open orders for storing, retrieving, or transferring are present for a storage channel, the control device places at least a first and a second active or open order in a sequence;
• b1. for a first active or open order, the control device calculates an expected end point in time of an order run time or a point in time at which a shuttle performing this first order is expected to arrive at the channel entrance;
• b2. the control device calculates for a second active or open order an expected end point in time of an order run time or a point in time at which a shuttle performing this second order is expected to arrive at the channel entrance;
• c1. the control device compares the points in time calculated for both orders according to b1 and b2;
• and
• d1. if the point in time calculated according to b2 for the second order is present before the point in time calculated according to b1 for the first order, the control device modifies the first order and/or the second order.
