摘要:
Woodworking machines and safety methods for use with those machines are disclosed. The machines include a detection system adapted to detect one or more dangerous conditions and a reaction system associated with the detection system. The reaction system can include an explosive to trigger the system, and also can be configured to retract a cutting tool at least partially away from a cutting region upon detection of a dangerous condition by the detection system.

A detection device and a detection method are provided for robot-induced loads that can act upon the human body in contact with the robot during a working process. The robot-induced loads, in particular forces, are measured by the measuring device (16) of an external sensing device (2). The measuring device (16) is suitably positioned and oriented in this process in the working area of an industrial robot (3) by means of a positioning device (15).

A food preparation apparatus is presented that has fast-stop capability. It includes a base unit, a mixing container attached to the base unit, a mixing tool configured to extend into and move within the mixing container, and a motor within the base unit. The motor is configured to provide a torque to the mixing tool. A control unit within the base unit is connected to the motor. A contact sensor is connected to the control unit, and the control unit is configured to stop rotation of the motor when the contact sensor detects a touch of a human hand. In some cases, contact with the mixing tool stops the motor, and in other cases, contact with an outer surface or user interface of the base unit stops the motor.

A sensing mechanism (12) for detecting user contact with an active portion (26) of the power tool (10) is provided. In addition, a safety mechanism (14) for preventing prolonged user contact with the active portion (26) of a power tool (10) is provided. The safety mechanism (14) is configured to actuate upon receipt of a signal from the sensing mechanism (12). According to a first aspect, the safety mechanism (14) is arranged to rapidly displace the active portion (26) away from a user extremity. Alternatively, according to a second aspect, the safety mechanism (14) is arranged to rapidly urge an extremity of the user away from the active portion (26) of the power tool (10).

The invention relates to a switch strip (10) for an apparatus for detecting an obstruction (210) in the movement range (221) of a closure element (220), in particular of an automotive vehicle (200). The switch strip (10) comprises an inner electrode (20), an outer electrode (30) approximately concentrically surrounding the inner electrode (20) at a distance (D), and a space (40) filled with air, which is arranged between the outer electrode (30) and the inner electrode (20) and which is dielectric. Furthermore, the switch strip (10) comprises a spacer (50) which is deformable in a direction transverse to the longitudinal direction. The spacer (50) spaces and insulates the two electrodes (20, 30) from one another. The outer electrode (30) is deformable by a force (F) applied from the outside. The deformation of the outer electrode (30) is able to at least in portions bring the inner electrode (20) and the outer electrode (30) into contact with each other. Such a switch strip (10) is also referred to as a tactile switch strip (10).
摘要:
Table saws with safety systems are disclosed. The safety systems detect and react to dangerous conditions, such as contact between the blade and a person. The table saws may include a switch, a first light that illuminates to indicate the safety system is operable, and a second light that illuminates to indicate that the safety system is inoperable. The switch may not power the saw when switched on if the second light is illuminated.
摘要:
A first electrode and a second electrode carry out welding in cooperation with each other. A power supply applies a first voltage between the first electrode and the second electrode. A control device controls whether to carry out welding on a first object on the basis of information that varies with a material of the first object and that has been detected in a state where the first object is in contact with the first electrode and the second electrode.
摘要:
The invention is based on a power tool, in particular a stationary saw, having a guard device which has a guard element. It is proposed that the guard device has an actuator system, which is provided for monitoring an opening which is formed at least by the guard element and is adaptable to at least one geometric feature of a workpiece.
摘要:
The invention describes a safety system (100) for a working machine (1), wherein an operator (7) is able to interact with the machine (1), wherein the system (100) comprises a transceiver unit (71) associated with the operator (7), a central processing unit (11), associated with the working machine (1), so as to receive signals from the transceiver unit (71), conductive gloves (81) comprising electrical conduction means (85, 84) configured to operate in ordinary functioning (I) or in an alarm condition (II), electrical connection means (82) configured to connect the transceiver unit (71) to the conductive gloves (81), and wherein the central processing unit (11) is configured to recognize whether the operator (7) is authorized for use of the machine (1), and to transmit an alarm signal (Sx1) so as to disable the machine (1) if the second operative condition (II) occurs.
