초록 ▼

Safety equipment for machinery used in processing plates, etc., such as presses and shearing machines which are operated with great power, where, lest the operator\s hands, fingers or some other part of the body be caught or cut because of an error in his operation of these machines for processing plates, etc., an insulating mat in which a wire netting is embedded is placed for supporting the operator in front of the machine for processing plates, etc., and high-frequency electric power is applied to said wire netting from a high-frequency electric power source in such a manner that a high-frequency electric field may be formed around the operator standing on the mat, that the said high-frequency electric field may be sensed by an antenna installed adequately in the vicinity of the danger zone of the machine for processing plates, etc., and as the operator\s body approaches said zone, that a signal from the high-frequency electric field may be sent to a high-frequency receiver and that the output of the receiver may be transmitted to an electronic switch, making it possible to control the machine for processing plates, etc., for safety purposes and a safety tester for said safety equipment used in the operation of machinery for processing plates, etc., which is used for checking whether or not the said safety equipment for the machinery used in processing plates, etc., works satisfactorily before their operation is started.

대표청구항 ▼

A safety device for machinery, particularly machinery for processing plates and the like, comprising an insulating mat having an embedded electrically conductive grid and being adapted to carry an operator who is in working position adjacent to the machine; safety means for stopping the machine in the event part of the operator\s body approaches a dangerous area of the machine, comprising a first source of high-frequency electrical energy connected to said grid so that a high-frequency field is formed about the body of the operator on said mat, a first antenna on said machine and positioned to sense said field when part of the operator\s body approaches said dangerous area and to generate a first signal, and first means for stopping said machine in response to generation of said first signal: and fail-safe means comprising a second antenna on said machine and operative to sense an absence of said field about the operator\s body and in response to generate a second signal, and second means for stopping said machine in response to generation of said second signal.
