Problems solved by technology
However, in the case of an emergency stop switch in the form of an icon displayed on the touch panel, the operator must pay attention to the touch panel, and it is inferior in ease of intuitive operation compared to a mechanical emergency stop switch.
In addition, depending on the usage environment of the mobile device, the visibility of the touch panel changes due to the increase and decrease of ambient light, and it may be difficult to recognize the emergency stop switch in the form of an icon.
In addition, there is also the possibility that the emergency stop switch in the form of an icon cannot be recognized due to a malfunction of the display function of the touch panel.
In addition, when the touch panel is stained with water droplets or the operator is wearing gloves, the operator's touch operation on the touch panel may not be correctly recognized, and safety cannot be ensured.

The invention provides an emergency stop system (1) which achieves the mechanical emergency stop through a portable device (2). The emergency stop system (1) includes: an emergency stop switch (11) including an operation button (21), a state output unit (22) which outputs a state different in accordance with whether or not the operation button (21) is pushed down, and an attachment unit which attaches the operation button (21) and the state output unit (22) to the mobile device (2) in a detachable manner in such a manner that the state of the state output unit (22) is positioned at a side facing a camera of the mobile device (2) at the time of attachment to the mobile device (2); and an information processing unit (12) which determines in accordance with an image related to the state of the state output unit (22) as imaged by a camera (41) whether to output an emergency stop signal indicating an emergency stop of the machine operated by the mobile device (2) or to output an emergency stop signal indicating no emergency stop of the machine.
Description
Technical field [0001] The present invention relates to an emergency stop system for emergency stop of a machine operated by a portable device. Background technique [0002] In order to operate robots, CNC machine tools, etc. (hereinafter sometimes referred to as "machines"), a mobile wireless instruction operation panel connected to the control device of the machine via wireless communication is used. In such a machine system, in order to avoid unexpected actions of robots or machine tools and ensure the safety of surrounding machines and operators, an emergency stop button is provided on the wireless instruction operation panel. [0003] Figure 17 It is a schematic diagram of a general mechanical system composed of a robot control device and a wireless instruction operation panel. The control device 102 that controls the robot 103 and the mobile wireless instruction operation panel 101 are connected by wireless communication. The operator can use the wireless instruction operat...
