Description
Technical field
The invention belongs to machinery fields, and in particular to a kind of bender Intelligent human body protector.
Background technology
Bender product lacks safeguard measure within the scope of tool travel at present, although the increase travel switch having, fine motion
Switch or infrared switch, but since human body and workpiece to be machined cannot be distinguished in its sensor, in bender cutter dropping process
In be easy to be interfered bender caused to malfunction.Secondly, existing bender emergency stop measure is to allow cutter to stop pushing, and keep
Cutter is parked in a certain fixed position, and it is to lean on oil cylinder working-pressure rather than mechanical brake to keep the action, after equipment is used for a long time, oil cylinder
Seal aging may result in brake failure, and there are great security risks.
Invention content
The present invention is directed to problems of the prior art, and human body can be distinguished and be added during routine use by providing one kind
Work workpiece does not influence to ensure the bender intelligent human-body protection dress of operating personnel's personal safety under the premise of bender normal process
It sets.
The technical solution adopted by the present invention is as follows：
A kind of bender Intelligent human body protector, bender include sliding block（4）And cutter（5）, which is characterized in that described device
Including linear encoder（2）, pyroelectric infrared sensor（3）, safe light curtain（7）, multiple infrared tubes（8）, 2 resets press
Button, programmable logic controller (PLC)；The linear encoder（2）Including incuding scale（1）And reader（6）, the uniform enconding
Device（2）It is installed on the cutter（5）Side；The pyroelectric infrared sensor（3）It is installed on the sliding block（4）The back side it is upper
Portion；The multiple infrared tube（8）Equidistantly arrangement, the safe light curtain（7）By the multiple infrared tube（8）What is sent out is red
Outside line is formed, the multiple infrared tube（8）With the cutter（5）It is parallel and be respectively positioned on the cutter（5）Underface；Institute
State linear encoder（2）, the pyroelectric infrared sensor（3）, the multiple infrared tube（8）, 2 reset button point
It is not connected with the programmable logic controller (PLC).
According to above-mentioned device, which is characterized in that the multiple infrared tube（8）Close to the cutter（5）Range
One group of infrared tube of upper end and the cutter（5）The distance of range upper end is no more than 100mm；The multiple infrared tube
（8）One group of infrared tube close to operation plane is no more than 11.25mm at a distance from operation plane.
According to above-mentioned device, which is characterized in that after described device makes bender be stopped, the safe light curtain（7）
Alarm release and when pressing 2 reset button simultaneously, bender works on.
Beneficial effects of the present invention：The present invention can intelligently distinguish human body and workpieces processing during bender use,
When non-processing part is put into bending machined region by operating personnel, bender can be stopped in time and push work and send out cutter lifting and refer to
It enables, effective protection operating personnel's personal safety prevents accident.
Description of the drawings
Fig. 1 is the general structure schematic diagram of the present invention；
Fig. 2 is the left view of Fig. 1.
Specific implementation mode
Referring to Fig. 1 and Fig. 2, a kind of bender Intelligent human body protector, bender include sliding block 4 and cutter 5, device packet
Include linear encoder 2, pyroelectric infrared sensor 3, safe light curtain 7,2 reset button, programmable logic controller (PLC)s；It is linear to compile
Code device 2 is installed on 5 side of cutter；Pyroelectric infrared sensor 3 is installed on the top at 4 back side of sliding block；Between multiple infrared tubes 8 etc.
Away from arrangement, the infrared ray that safe light curtain 7 is sent out by multiple infrared tubes 8 is formed, multiple infrared tubes 8 it is parallel with cutter 5 and
It is respectively positioned on the underface of cutter 5, one group of infrared tube and 5 range upper end of cutter close to 5 range upper end of cutter
Distance is no more than 100mm, and one group of infrared tube close to operation plane is no more than 11.25mm at a distance from operation plane；Linearly
8,2 encoder 2, pyroelectric infrared sensor 3, multiple infrared tubes reset button respectively with programmable logic controller (PLC) phase
Even；After device makes bender be stopped, 7 alarm release of safe light curtain and when pressing 2 reset button simultaneously, bender continues
Work.
Pyroelectric infrared sensor 3 can detect the infrared ray of human body radiation in the form of non-contact, and be transformed into electricity
Signal is pressed, meanwhile, it is biology or abiotic that it, which can also identify movement,.
When cutter 5 falls, bender Intelligent human body protector is activated, at this time if there is human body enters cutter 5
In stroke range, pyroelectric infrared sensor 3 and safe light curtain 7 will be triggered simultaneously, and the infrared ray that infrared tube 8 is sent out is hidden
When gear, device sends out shielding signals, controls potentially dangerous mechanical equipment and is stopped, and avoids that safety accident, knife occurs
Tool 5 will stop falling at once and be lifted up.
In order to make device distinguish cutter 5 and human body, without influencing bender normal use, in 5 side of cutter, installation is linear
Encoder 2 is moved as distance of fall element is measured with cutter 5 together.Linear encoder 2 consists of two parts：6 He of reader
Incude scale 1, it, can be without frictionally determining position using contactless measurement.Sensor 6 is detected by unique code to be incuded
Absolute position on scale 1, and information is directly transferred to programmable logic controller (PLC), there is no need to reference to running, structure is tight
It gathers, high resolution.It is measured by linear encoder 2, when cutter 5 falls, the infrared ray 2mm-3mm that is sent out apart from infrared tube 8
When, this group of infrared tube 8 fails, and when cutter 5 makes last group of infrared tube 8 fail, cutter 5 is apart from operation plane at this time
12.25mm, has been enter into safety work distance, has not only ensured the normal use of bender, but also the personal safety of protection operating personnel.
Programmable logic controller (PLC) uses a siemens PLC as control centre, and signal is accessed programmable logic
It is controlled in controller.When cutter 5 is run down, if there is human body enters 5 stroke range of cutter, programmable logic
Controller monitors the trigger signal that pyroelectric infrared sensor 3 and the infrared tube not failed 8 are sent out, programmable logic simultaneously
Controller will control bender break-off and send shifting signal on cutter 5.In addition 2 signal of linear encoder is accessed programmable
In logic controller supercomputing interface, operation is carried out by programmable logic controller (PLC) internal program, calculates distance of fall, to really
Which fixed group infrared tube 8 fails.
In order to improve operating personnel's vigilance, device carries 2 reset button, when 7 alarm release of safe light curtain and simultaneously
2 reset button are pressed, bender can continue work.
