An automated storage and retrieval system includes a three-dimensional storage grid for storing storage containers; first and second container handling vehicles operating on the storage grid; and a central communication system for controlling and communicating with the container handling vehicles for handling storage containers in the storage grid. The automated storage and retrieval system includes a barrier separating the three dimensional storage grid into a first section and a second section. The barrier has two states: a first state in which the container handling vehicles are allowed to move between the first section and the second section; and a second state, in which the container handling vehicles are physically prevented from moving between the first section and the second section by means of the barrier.

The invention relates to a control method for a quick change device of a work tool, comprising the steps of: receiving a command to disengage a work tool clamping device; determining whether the work tool clamping device is in an engaged state; detecting functionality of a disengagement alarm if the work tool is in the engaged state; switching to an emergency state upon the detection of failure of the disengagement alarm. The present invention further relates to a corresponding control apparatus and work machine.

An automated storage system includes a three-dimensional storage grid for storing storage containers, at least one container handling vehicle operating on, around or under the storage grid, and a central communication system with a system transmitter and a system receiver for controlling and communicating with the at least one container handling vehicle for handling storage containers in the storage grid. At least one container handling vehicle includes a vehicle communication system with a vehicle transmitter and a vehicle receiver for communication with the central communication system. The system and vehicle transmitters and receivers are configured to use light for wireless communication. The system transmitter and the system receiver are located in the automated storage system on, around, or under the storage grid transmitting the same communication from all the transmitters of the central communication system.

A device for a controlled locking or release of a safety-relevant, movable component (2), such as a protective door, protective cover of the like, with a movable blocking element (51) and with a self-locking drive unit (5, 17, 19, 21, 23, 27) controlling adjustment movements of the blocking element (51) between a locked position and a released position is characterized in that an actuator (33) is provided that can be moved by the drive unit (5, 17, 19, 21, 23, 27), said actuator being mechanically coupled to the blocking element for a transfer of the blocking element (51) into the released position brought about by the drive unit (5, 17, 19, 21, 23, 27) and being capable of decoupling for a transfer of the blocking element (51) into the released position brought about independently of the drive unit (5, 17, 19, 21, 23, 27).

An interlocking device for locking a movable safety guard has a locking unit, an electric mover, an additional release unit, a sensor device and an evaluation unit. The locking unit is movable between a locking position for interlocking the movable safety guard and a release position for releasing the movable safety guard and the mover is configured to move the locking unit between the locking position and the release position. The additional release unit is movable from a neutral position into an additional release position to move the locking unit from the locking position into the release position. The sensor device is configured to detect a position of the locking unit and a position of the additional release unit. The evaluation unit is configured to output a locking signal, a normal release signal, and an additional release signal.
