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 punch press technical field, is specifically 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 the safety of operator, 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 infrared ray is stopped by the hand of operator, safe grating break-make information module transmits a signal to punch press control module, 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 carried out in a large amount of enterprise, operator often only needs the operation constantly repeating single operation, so repeat the operation of single operation, often easily cause operator tired, particularly in operating punch machine process, operator puts into work bench of punch press when slide block rises stock, slide block is that mould can by perpendicular to folding mould direction or the die assembly with the angled slip in folding mould direction in die sinking action, after slide block punching press completes, operator takes out stamping forming product and puts into new stock, so constantly repeat, very easily cause operator tired, operator's fatigue just easily makes risky operation later, and the safe grating on existing punch press can only control punch press when operator makes risky operation, as operator's handle when the downward punching press of slide block puts into work bench of punch press, now safe grating break-make information module controls punch press shutdown, only just safeguard protection can be carried out when risky operation occurs, can not take precautions against because operator is tired and produce risky operation, once 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, thering is provided can whether fatigue judges to punch press operator, and whether can be in operator and be easy to tired time zone and judge, effectively can monitor the duty of operator, risky operation is made, with the tired judgment means of the operating punch machine person increasing the security of punch press after avoiding operator's fatigue.
For solving the problems of the technologies described above, the tired judgment means of operating punch machine person provided by the invention, it comprises the safe grating break-make information module and punch press control module that punch press carries, first signal output part of safe grating break-make information module is electrically connected with the first signal input part 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 part of single-chip microcomputer, the secondary signal input of punch press control module is electrically connected with the first signal output part of single-chip microcomputer, the secondary signal output of safe grating break-make information module is electrically connected with the secondary signal input of single-chip microcomputer, the secondary signal output of single-chip microcomputer is electrically connected with the signal input part of fatigue warning module.
After adopting above structure, the present invention compared with prior art, has following advantage:
Whether fatigue judges to punch press operator to utilize single-chip microcomputer, and can by the working time of the single-chip microcomputer person that comes Clocked operation, thus judge whether operator is in and be easy to tired time zone, be easy to tired time zone i.e. operator and easily produce the tired time period, thus effectively can monitor the duty of operator, make risky operation after avoiding operator's fatigue, greatly reduce the generation of risky operation, considerably increase the security of punch press.
As preferably, three kinds of different alarm voices are preserved in described fatigue warning module, be respectively fatigue warning voice, tired rear continuous firing alarm voice, be easy to tired time zone alarm voice, the different control signal that can send according to single-chip microcomputer, send corresponding alarm voice.
Another technical problem to be solved by this invention is, thering is provided can whether fatigue judges to punch press operator, and whether can be in operator and be easy to tired time zone and judge, effectively can monitor the duty of operator, risky operation is made, with the tired determination methods of the operating punch machine person increasing the security of punch press after avoiding operator's fatigue.
