Abstract
The utility model belongs to the metal processing facility field, in particular to protector who is used for improving horizontal strap saw. Horizontal strap saw protector, its characterized in that: including installing the safety inspection grating on horizontal strap saw, still include the PLC controller, the PLC controller is connected with the safety inspection grating, the PLC controller still is connected with the spindle motor of horizontal strap saw. The utility model discloses an adopt the grating protector of PLC control, can detect by the staff, judge the work area that has or not the staff to get into the saw to the rotation in area is sawed in control, guarantees operating personnel's safety, avoids the incident owing to personnel's carelessness causes.
Description
Technical field
This utility model belongs to metal-working plant field, more particularly to a kind of for improving the anti-of horizontal metal band sawing machine
Protection unit.
Background technology
Horizontal metal band sawing machine of the prior art does not have preventer, and when equipment works, the handss of operator can be with
Working area is stretched into, may so cause the problem of finger sawing injury.
Utility model content
For above-mentioned technical problem, this utility model devises a kind of grating preventer of employing PLC controls, Neng Gouren
Handss are detected, determine whether staff into the working region of saw, so as to control the rotation of saw band, it is ensured that the peace of operator
Entirely, it is to avoid due to the security incident that personnel's carelessness is caused.
Realize that the technical solution of the utility model is as follows：
Horizontal metal band sawing machine preventer, it is characterised in that：Including the safety inspection on horizontal metal band sawing machine
Light-metering grid, also including PLC, PLC is connected with safety detection grating, the PLC also with horizontal metal
The spindle motor connection of band sawing machine.
Alarm device is connected with described PLC.
The electromagnetic valve for adjusting band position is connected with described PCL controllers.
Described safety detection grating is arranged on the front of the saw band working position of horizontal metal band sawing machine.
Described alarm device includes the audio alert unit being connected with PLC and light warning unit.
In sum, this utility model has the advantages that:
This utility model by arrange safety detection grating staff is detected, when have staff enter safety detection light
After the detection range of grid, safety detection grating feedback signal controls horizontal metal band sawing machine to PLC, PLC
Spindle motor quits work, and makes saw band stop operating, so as to avoid staff from entering the potential safety hazard of saw working region presence
Problem.
Description of the drawings
Fig. 1 is schematic view of the mounting position of the safety detection grating on horizontal metal band sawing machine；
System composition figures of the Fig. 2 for preventer；
In figure, 1 is safety detection grating, and 2 is horizontal metal band sawing machine, and 3 is PLC, and 4 is spindle motor, and 5 are electricity
Magnet valve, 6 is alarm device, and 61 is audio alert unit, and 62 is light warning unit.
Specific embodiment
It is for making purpose, technical scheme and the advantage of this utility model embodiment clearer, new below in conjunction with this practicality
The accompanying drawing of type embodiment, is clearly and completely described to the technical scheme of this utility model embodiment.
As depicted in figs. 1 and 2, horizontal metal band sawing machine preventer, including the peace on horizontal metal band sawing machine 2
Full inspection light-metering grid 1, safety detection grating 1 for whether having object to detect into sawing machine working position, when staff is through peace
During full inspection light-metering grid, safety detection grating feedback signal to PLC, also including PLC 3, PLC 3 and peace
Full inspection light-metering grid 1 connect, and PLC 3 is used for receiving the signal of safety detection grating feedback 1, and is done according to the logic of setting
Going out corresponding judgement, and control the system component of correlation carries out action, the PLC 3 also with horizontal metal band sawing machine
Spindle motor 4 connects, and PLC 3 can control the work of spindle motor 4, and spindle motor 4 provides dynamic for saw when normal
Power, when abnormal, spindle motor is stopped operating at once, and provides brake drag, overcomes the inertia of saw band, enables saw quick
Stop.
Alarm device 6 is connected with described PLC 3, when PLC control spindle motor stop operating it is same
When send a signal to alarm device, alarm device sends voice and photosignal reminds operator to take care.
The electromagnetic valve 5 for adjusting band position is connected with described PCL controllers 3, when safety detection grating feedback
After signal is to PLC, PLC control electromagnetic valve work is adjusted the position of saw band, saw band is separated with workpiece, keep away
Exempt from the generation of security incident.
Described safety detection grating 1 is arranged on the front of the saw band working position of horizontal metal band sawing machine 2, installed in saw band
The front of working position, mainly prevents the handss of operator from entering the working region of saw band.
Described alarm device 6 includes the audio alert unit 61 being connected with PLC and light warning unit 62, examines in safety
After light-metering grid feed back signal to PLC, there is audible ringing signal in PLC control voices alarm unit, from acoustically to behaviour
Alerted as personnel, and light warning unit can also be occurred warning light, and visually operator are warned.
The course of work of the present utility model：
The first：State when saw blade operates
In this state, spindle motor is operating, once handss are stretched into cutting zone by someone will amputate finger, institute
It is once safety detection grating feedback signal is to PLC with the strategy taken in this state, then PLC is stood
Allow and spindle motor power-off brake, at the same time will be immediately performed sawing machine halt instruction, and to control solenoid valves 2.5 seconds
, there is audible ringing signal and light warning signal in (about rising 10 millimeters), then alarm device work.
Second：State when saw blade does not operate
If saw blade is in the state that shuts down, it is also possible to workman come off duty sweep lathe, be also likely to be sawing machine
Adjustment moulds of industrial equipment, if now someone passes through the light curtain of safe grating, then PLC can lock saw blade operating button simultaneously
The contactor coil loop of spindle motor is disconnected, other functions are normal, stepping up when so ensuring that adjustment moulds of industrial equipment,
The operations such as release, rising, decline, it is also possible to which Pneumatic water pump rinses machine-tool platform face, but can not exactly allow bands for band to operate, so as to
Protect the safety of workman.
In sum, this utility model has the advantages that:
This utility model by arrange safety detection grating staff is detected, when have staff enter safety detection light
After the detection range of grid, safety detection grating feedback signal controls horizontal metal band sawing machine to PLC, PLC
Spindle motor quits work, and makes saw band stop operating, so as to avoid staff from entering the potential safety hazard of saw working region presence
Problem.
