Abstract
The invention discloses a punch operator fatigue judgement system, which comprises a safety light curtain on-off information module, a punch control module, a singlechip and a fatigue alarm module. The invention also discloses a punch operator fatigue judgement method. By calculating the difference between the time when the hands of an operator enter a safety light curtain and the time when the hands of the operator leave the safety light curtain, the singlechip works out the feeding rate of the operator to judge whether the operator is in a tired state or not, whether the operator is in an easy-to-fatigue time range or not is judged according to the working hours of the operator counted by the singlechip, and a corresponding alarm voice is emitted. The punch operator fatigue judgement system can effectively monitor the working state of the operator to prevent the tired operator to conduct dangerous operation, thus enhancing the safety of a punch.
Description
Technical field
The present invention relates to the punch press technical field, specifically is the tired judgment means of a kind of operating punch machine person and method.
Background technology
Along with improving constantly of punch press automaticity; safety problem more and more receives publicity; in order to protect operator's safety; safe grating has become an important device of punching machine safety; safe grating comprises RF transmitter; infrared receiver and safe grating break-make information module; safe grating break-make information module is electrically connected with RF transmitter and infrared receiver respectively; in the process of the downward punching press of slide block; when the infrared ray person's of being operated hand stops; safe grating break-make information module transmits a signal to the punch press control module, and the punch press control module forces to make punch press out of service.
Along with enterprise's production division of labor is more and clearer and more definite; pile line operation is at a large amount of Enterprises; the operator often only need to constantly repeat the operation of single operation; so repeat the operation of single operation; often cause easily the operator tired; particularly in the operating punch machine process; the operator puts into work bench of punch press to stock when slide block rises; slide block be mould in the die sinking action can by perpendicular to folding mould direction or with the die assembly of the angled slip of folding mould direction; the operator took out stamping forming product and puts into new stock after the slide block punching press was finished; so constantly repetitive operation; very easily cause the operator tired; operator's fatigue is just made later on risky operation easily; and the safe grating on the existing punch press can only be controlled punch press when the operator makes risky operation; put into work bench of punch press such as operator's handle when the downward punching press of slide block; safe grating break-make information module control this moment punch press is shut down; only when occuring, risky operation just can carry out safeguard protection; can not take precautions against owing to operator's fatigue produces risky operation; in case safe grating is malfunctioning; as easy as rolling off a logly cause personal injury, this can reduce the security of punch press undoubtedly.
Summary of the invention
A technical problem to be solved by this invention is, providing can whether fatigue be judged to the punch press operator, and can whether be in the operator and be easy to tired time district and judge, can effectively monitor operator's duty, avoid making risky operation after operator's fatigue, with the tired judgment means of operating punch machine person of the security that increases punch press.
For solving the problems of the technologies described above, the tired judgment means of operating punch machine person provided by the invention, it comprises safe grating break-make information module and the punch press control module that punch press carries, the first signal output of safe grating break-make information module is electrically connected with the first signal input of punch press control module, described operating punch machine person is tired, and judgment means also comprises single-chip microcomputer and fatigue warning module, the signal output part of punch press control module is electrically connected with the first signal input of single-chip microcomputer, the secondary signal input of punch press control module is electrically connected with the first signal output of single-chip microcomputer, the secondary signal output of safe grating communication module is electrically connected with the secondary signal input of single-chip microcomputer, and the secondary signal output of single-chip microcomputer is electrically connected with the signal input part of fatigue warning module.
