Description
Technical field
The utility model belongs to electric equipment field, is related to a kind of electrical safety protector for automatic pipebender.
Background technology
At present, in mechanical processing industry, it is wide that automatic pipebender produces the advantages of Product Precision is high, production efficiency is high with it
In the general processing applied to various tubings, its electrical safety protector is used as machine and operating personnel's personal safety
Safeguard is indispensable.The main Damage site of automatic pipebender is that head turns round position, but equipment is in actual use
In only in head backhaul use safety protection guard, equipment carry out bend pipe operation when using safety device to behaviour
Make, support staff carries out installation protection.So, need a kind of safety that security protection can be carried out in bend pipe operation of development badly and fill
Put and equipment and personnel are protected.
Utility model content
The purpose of this utility model be to provide it is a kind of it is simple and compact for structure, be easily installed the safety device used, and energy
It is enough to provide continual protection when automatic pipebender head carries out revolution operation, while requiring that its protective range can be according to need
Ask and be adjusted.
The technical solution of the utility model is：For the electrical safety protector of automatic pipebender, including：Power supply is opened
Pass, distance adjustable infrared sensing switch, infrared sensing switch output relay, start button, output relay first are normally opened
Contact, stop button, emergency stop button, infrared sensing switch output relay normally-closed contact, output relay, output relay
The normally opened contact of device second, equipment emergent stopping control relay.Opened by distance adjustable infrared sensing switch and infrared induction
Close parallel connection after output relay series connection and enter main control loop, while start button is in parallel with the normally opened contact of output relay first
Afterwards, connected with stop button, emergency stop button, infrared sensing switch output relay normally-closed contact and output relay
Main control loop is entered in parallel connection afterwards, will be in parallel after the normally opened contact of output relay second and the series connection of equipment emergent stopping control relay
Enter main control loop, power switch series connection is entered into main control loop.
The utility model can reach following beneficial effect after using above-mentioned technical proposal：The protection domain of the safety device is
By the way that distance adjustable infrared sensing switch is installed on equipment bending mechanism, then adjust distance of reaction to form one
Individual fan-shaped induction region, the induction region is run with equipment bending mechanism, can be real in whole pipe fitting process
Now to the protection of equipment and personnel.The protecting effect of the safety device is that equipment is normally transported when personnel keep off protection zone
OK, equipment is out of service if having personnel to enter protection zone, needs to carry out start-up operation after personnel leave protection zone
After continue executing with bend pipe program, the elbow member without changing, reduce waste product output.
Brief description of the drawings
Fig. 1 is the circuit diagram for the electrical safety protector that the utility model is used for automatic pipebender.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.As illustrated, for the electric of automatic pipebender
Safety device, mainly includes：Power switch 1, distance adjustable infrared sensing switch 2, infrared sensing switch output relay
Device 3, start button 4, the first normally opened contact of output relay 5, stop button 6, emergency stop button 7, infrared sensing switch are defeated
Go out relay normally-closed contact 8, output relay 9, the second normally opened contact of output relay 10, equipment emergent stopping control relay
11.Parallel connection is entered after the device is mainly connected by distance adjustable infrared sensing switch 2 and infrared sensing switch output relay 3
Main control loop, at the same by start button 4 it is in parallel with the first normally opened contact of output relay 5 after with stop button 6, emergent stopping
Button 7, infrared sensing switch output relay normally-closed contact 8 and output relay 9 connect and then parallel connection is entered main control and returned
Road, main control is entered in parallel connection after then the second normally opened contact of output relay 10 and equipment emergent stopping control relay 11 are connected
Loop, finally will constitute whole control device by the way that power switch 1 is connected into main control loop.The device is opened by power supply
It is distance adjustable infrared sensing switch 2, infrared sensing switch output relay 3, output relay 9, equipment emergent stopping to close 1
Control relay 11 and whole control loop provide power supply, and infrared sense is controlled by distance adjustable infrared sensing switch 2
Inductive switch output relay 3, relay is exported by start button 4, stop button 6, emergency stop button 7, infrared sensing switch
Device normally-closed contact 8 and output relay 9 constitute the first control loop, and this time is realized by the first normally opened contact of output relay 5
Road self-locking, the second control loop is constituted by the second normally opened contact of output relay 10, equipment emergent stopping control relay 11,
The purpose of control device emergent stopping is reached by control device emergent stopping control relay 11.
The device is mainly characterized by：When no personnel are close to induction region, safety device start button 4 is pressed, it is defeated
Go out the adhesive of relay 9, so as to keep the circuit to connect using the first normally opened contact of output relay 5, utilize output relay the
Equipment emergent stopping control loop is connected in two contacts 10, equipment is normally run.If personnel are close to distance during induction region
Adjustable infrared inductive switch 2 is acted, and the adhesive of infrared sensing switch output relay 3, infrared sensing switch output relay is normal
Closed contact 8 is disconnected, and output relay 9 is powered off, so that off device emergent stopping control relay 11, makes equipment downtime, is realized
Protect the purpose close to personnel.
The protection domain of the safety device is by the way that distance adjustable infrared sensing switch is installed into equipment bending mechanism
On, distance of reaction is then adjusted so as to form a fan-shaped induction region, and the induction region is transported with equipment bending mechanism
OK, the protection to equipment and personnel can be realized in whole pipe fitting process.The protecting effect of the safety device be
Equipment is normally run when personnel keep off protection zone, and equipment is out of service if having personnel to enter protection zone, in personnel
Leave needs to continue executing with bend pipe program after carrying out start-up operation behind protection zone, and the elbow member without changing reduces waste product production
Go out.
The utility model is simple and compact for structure, transformation is simple, carry out power supply supply, replicability using original equipment power supply
By force, it can be produced to automatic pipebender and provide a kind of effective equipment safety protectiving scheme using enterprise.
