Description
Technical field
The utility model is related to sheet material handling facilities technical field, more particularly to plastic profiled bar extrusion die traction cutting
Machine.
Background technology
Only had protective cover to protect operator in the traction cutting machine of plastic profiled bar extrusion die downstream subsidiary engine equipment in the past
Safety, when the dodge gate of protective cover is closed, operator is just unlikely to have contact to draw the chance of crawler belt and cast-cutting saw slice；And
Some section bar manufacturers are not paid attention to safety in production, often in order to opening wide protective cover conveniently and in process of production
Dodge gate, once protective cover dodge gate is in open mode, because machine is still operated, operator or other staff are very possible
Because inadvertent general idea causes the generation of security incident.
In order to prevent unexpected generation, the supporting security system of domestic traction cutting machine institute is opened using gate control fine motion is lifted at present
Close, such as Chinese utility model patent application number CN200920186866.0 discloses plastic profiled bar extrusion die traction cutting
Machine, including protective cover, protective cover, which is provided with dodge gate, the doorframe of dodge gate to be equipped with when dodge gate is opened, can be cut off traction shoe
The microswitch of powered electromechanical source.Work as lift slide door（Dodge gate）When being opened, microswitch can disconnect electric control system control
Power supply stops that the operation of whole equipment reaches the purpose of protection personal safety with this.There is major hidden danger in such a security system：1、
There is no design safety door lock, the continuous operation of production is influenced whether when someone opens the door.2nd, microswitch is not secured electrical in itself
Element, once failure, personal safety can not be ensured.3rd, circuit double loop redundancy can not be designed, International Safety Certification mark is not met
It is accurate.Reason is as follows：Production just starts or continuously produces the long period, and now internal pair production meets with failure such as section bar off normal
Need staff to open lift slide door, but hauling machine operation can not be stopped again, the method taken is exactly in advance in regulator cubicle
Microswitch is shielded, lift slide door maintenance is now opened again.This method wasted time and energy and do not say, once shielding harness breaks down
（Comparatively vibrations device interior easily breaks down）Personal safety can meet with significant threat.New international safety standard
ISO 13849-1 are elaborated to safety specifications and safe class, and security function is by some and security phase
The ability for the resisting risk that the component of pass is realized.Safe class is from low to high：B-1-2-3-4, five grades, B grades system
One failure of system feature may cause the forfeiture of security！Domestic conventional traction cutting security system belongs to B grades.Therefore improve
Processing safety is very necessary.
Utility model content
The technical problems to be solved in the utility model is that existing traction cutting machine of plastic profiled material extrusion mold opens work
There is potential safety hazard during dynamic door, providing a kind of plastic profiled bar extrusion die with safety control for this draws cutting
Machine.
The technical solution of the utility model is：Plastic profiled bar extrusion die traction cutting with safety control
Machine, it includes dodge gate, traction cutting machine body, scram button and the servomotor for driving traction cutting machine body, it
Also include being placed in the safety door switch on dodge gate, the control handle with key, relay, contactor and servo-driver,
The scram button is connected by relay with contactor signal, and the control handle with key passes through relay and safety door
Switching signal is connected, and the contactor, servo-driver and servomotor are sequentially connected electrically.
The improvement of such scheme is that the output loop of the relay has also accessed indicator lamp.
Relay described in such scheme is G9SE type safety relays.
Safety door switch described in such scheme is D4SL type safety door switchs.
The beneficial effects of the utility model are that safety door switch can be controlled by the control handle with key, scram button control
Servomotor jerk, improves the functional reliability and security of traction cutting machine of plastic profiled material extrusion mold.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram；
Fig. 2 is the electrical module figure of safety control；
In figure, 1, dodge gate, 2, traction cutting machine body, 3, scram button, 4, servomotor, 5, safety door switch, 6,
Control handle with key, 7, relay, 8, contactor, 9, servo-driver, 10, indicator lamp.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, the utility model includes dodge gate 1, draws cutting machine body 2, scram button 3 and for driving
The servomotor 4 of dynamic traction cutting machine body, it also includes being placed in the safety door switch 5 on dodge gate, the control with key
Knob 6, relay 7, contactor 8 and servo-driver 9, the scram button are connected by relay with contactor signal, institute
State the control handle with key to be connected with safety door switch signal by relay, the contactor, servo-driver and servo
Motor is sequentially connected electrically.
Specifically, traction cutting machine body can include fixed mount, draw-gear and cutter device, described draw-gear
Fixed mount rear end is arranged at, fixed mount front end is provided with cutter device, and described draw-gear is made up of upper and lower traction crawler belt,
Draw crawler belt front end and be provided with servomotor, upper and lower traction crawler belt is provided with adjustment mechanism.
The preferred D4SL types safety door switch of safety door switch, the preferred G9SE types safety relay of relay, scram button leads to
The contact for crossing Control contactor is disconnected to control the emergent stopping of servomotor, and safety door switch normality is in closed form
State is locked by dodge gate, when need open dodge gate when by control handle to one signal of safety door switch so that dodge gate can
To open.The key of control handle is taken care of by qualified keeper, this guarantees common operating personnel in no key
In the case of can only be by pressing scram button so that safety door could be opened after machine down.And qualified keeper can be with
Control handle is opened by key, and then make it that safety door switch is opened in the case where machine runs well, dodge gate can be with
Open.
In order to improve safety coefficient in the case where opening control handle using key, best relay has also been accessed and band
The indicator lamp 10 of the control handle signal connection of key, so when dodge gate is opened, indicator lamp is lighted, and personnel on the scene are carried out
Alarm, reminds personnel on the scene to take care.
Relay of the present utility model, the control handle with key, safety door switch and scram button use secured electrical
Element, while the electric loop between them is designed with double loop redundancy.Ensure its functional reliability.
