A safety switch (2) with a latching unit (12), by means of which an associated actuator (3) is held in a latched position. The latching unit (12) has an opening (9) and a blocking element. In a latched position, the blocking element projects into the opening (9) and rear-engages an actuator head (8) of the actuator (3), which is in the latched position. The blocking element is held in the latched position by means of a positioning element with a setting force. When the actuator head (8) is inserted into or removed from the opening (9), the actuator head (8) pivots the blocking element out against the setting force.

A safety device (8) with a safety switch (7) and at least one actuator (9), wherein when an actuator (9) is arranged within a response range relative to the safety switch (7), signals are transmitted from the actuator (9) to the safety switch (7), by which means a function of the safety switch (7) is released. The actuator (9) is additionally designed for configuring the safety switch in that a configuration signal is transmissible from the actuator (9) to the safety switch (7).

A station for providing access to contents in a storage container of an automated storage and retrieval system comprising:—an access barrier comprising an opening, and a plurality of covers, wherein each cover is arranged to be selectively deployed to close off a respective portion of the opening;—a loading mechanism arranged to receive the storage container and move it to the opening of the access barrier; and—a housing which is able to prevent access to the opening of the access barrier; wherein the station (10) is arranged to transition between;—a loading configuration in which access to the opening of the access barrier is prevented by the housing, and—an access configuration in which the opening of the access barrier is presented to thereby enable access to contents of the storage container through the opening. The station is configured to deploy the covers to close off predetermined portions of the opening prior to transition into the access configuration to thereby restrict or permit access to contents of the storage container through predetermined portions of the opening.

A web material converting line is disclosed, in particular for converting tissue paper, including a plurality of converting sections arranged in sequence along a feeding direction of a web material to be converted, each section including a converting machine; at least one converting section of the converting line includes a detection system for detecting the presence of people near the converting section. The detection system includes at least a first presence sensor and is adapted to detect the presence of people in at least a controlled area. The controlled area is subdivided into an accessible area 5 that can be accessed when the line is working, and an alarm area. The detection system is adapted to distinguish between the presence of an individual in the accessible area and the presence of an individual in the alarm area. The detection system is connected to a control unit adapted to intervene on the operation of the converting section based on information provided by the detection system.

A machine tool including a fixed cover and a movable cover for covering at least part of a machining region includes a cover control device that includes a driving circuit for driving the movable cover, an abnormality detection device that detects an abnormality while the movable cover is driven, a self-diagnosis device that performs evaluation on whether the abnormality detection device is normal, and an output device that outputs a result of the evaluation by the self-diagnosis device. The self-diagnosis device is configured to perform the evaluation on whether the abnormality detection device is normal based on an operating state of the abnormality detection device at a time when a pseudo abnormality is generated on the movable cover by driving the movable cover via the driving circuit.

An image forming system comprises a first housing, a second housing and a third housing. The second housing may comprise a motor, a first door and a first switch. The first switch is provided on an electrical path connecting a power supply and the motor, for switching between a first state and a second state and for switching from the first state to the second state. The third housing may comprise a load. When the first door is opened in a state where the first switch is in the first state, the first switch switches from the first state to the second state to cause supply of electric power to the load to be cut off.
