The safety door switch of other brand and models can also be used in his embodiment.
The metal molten increasing material manufacturing equipment of present embodiment（Hereinafter referred to as " equipment "）Enabling control system be one
Kind PC+PLC control execution systems.In the following, the enabling control for shaping chamber door 110 is illustrated first.
When to open shaping chamber door 110, first detect whether to meet shaping chamber door door-opening condition, for example, detection device
Whether printing is being carried out, whether the pressure and temp in forming cavity reaches whether preset requirement, equipment are vacuumizing.
Specifically, for example, when detecting that equipment is not being printed, shaping chamber door 110 can be opened；When detecting forming cavity
External and internal pressure it is equal, i.e. shape intracavitary pressure it is equal with atmospheric pressure, can open shape chamber door 110；Shaped when detecting
When the pressure of intracavitary is positive pressure, i.e. the pressure of shaping intracavitary is more than atmospheric pressure, shaping chamber door 110 can be opened；When detecting into
The temperature of shape intracavitary is less than some temperature value（Such as 60 degree）When, shaping chamber door 110 can be opened；When detecting that equipment do not exist
When vacuumizing, shaping chamber door 110 etc. can be opened.
It is above-mentioned whether to meet that the detection for shaping chamber door door-opening condition can be achieved using existing common detection module, by
In such detection module known to those skilled in the art, thus do not repeat herein.
In the present embodiment, the safe door key 114 of safety door switch 120 is arranged in shaping chamber door 110, works as satisfaction
When shaping chamber door door-opening condition, safety door switch 120 is opened, and equipment is alarmed and emergent stopping.Specifically, when meet into
During shape chamber door door-opening condition, the instruction shaping chamber door 110 of safety governor module 130 can be opened, safety door switch 120 opens,
The safe door key 114 being arranged in shaping chamber door 110 slips off.In addition, the openable instruction of shaping chamber door 110 passes through peace
Full input/output module 140 is output to upper computer module 310, and the instruction of upper computer module 310 carries out alarm so as to prompt operator
Member's shaping chamber door 110 can be opened.When receiving shaping 110 openable alarm of chamber door, operating personnel need first to release report
Alert and then operation mechanical lock 112 is opened chamber door 110 is shaped, it is preferable that and it can be arranged to operating personnel's both hands and operate at the same time, one
Hand releases a hand of alarming and opens shaping chamber door 110.In addition, in the present embodiment, when satisfaction shapes chamber door door-opening condition
When equipment carry out emergent stopping, refer to that 130 commands relays 240 of safety governor module are acted so that equipment in this case
Emergent stopping, such as the action using relay 240, make the solenoid valve of control shaping intracavity gas disengaging close so as to stop setting
Standby vacuumizes；Or the action using relay 240, stop motor shaft so that equipment downtime, stopping print job.
In the present embodiment, the mode for meeting alarm during shaping chamber door door-opening condition for example can be alarm lamp flicker
The modes such as light warning, display screen picture prompting alarm, audible alarm.This alarm using existing common alarm module is
It can be achieved, belong to common knowledge, this kind of alarm module known to those skilled in the art, thus do not repeat herein.Separately
Outside, in the present embodiment, upper computer module 310 is for example configured to include industrial personal computer and in the industrial personal computer
Control software, upper computer module 310 are instructed by the control software and alarmed.
When being unsatisfactory for shaping chamber door door-opening condition, safety door switch 120 is failure to actuate, and equipment alarm simultaneously prompts " to hold
Row door opening action ".Specifically, when being unsatisfactory for shaping chamber door door-opening condition, the instruction shaping chamber door of safety governor module 130
110 cannot open, and then safety door switch 120 is not opened.In addition, the instruction that shaping chamber door 110 cannot be opened passes through peace
Full input/output module 140 is output to upper computer module 310, and the instruction alarm of upper computer module 310 is so as to prompt operating personnel " no
Door opening action can be performed " i.e. shaping chamber door 110 cannot open, with meet shape chamber door door-opening condition when as, be unsatisfactory for into
The mode of alarm during shape chamber door door-opening condition for example can be alarm lamp blinking light alarm, display screen picture prompting alarm,
The modes such as audible alarm, are instructed by its control software by upper computer module 310 and alarmed.
In addition, in metal molten increasing material manufacturing equipment, glove box door is typically opened in the operation for taking out printing workpiece successively
210 take out workpiece with shaping chamber door 110.Therefore, grasped to effectively prevent the enabling in equipment printing, vacuum from missing
Make, not only to prevent shaping chamber door enabling maloperation, should also prevent glove box door enabling maloperation.In the following, to glove box door
210 enabling control illustrates.
When glove box door 210 is opened, equipment alarm simultaneously stops.The opening of glove box door 210 is also by safety governor
Module 130 controls.Specifically, in the present embodiment, safety sensor 220 is arranged in glove box door, it is to gloves
The either on or off of chamber door 210 is detected, and when glove box door 210 is opened, safety sensor 220 is opened glove box door 210
Door information is output to safety governor module 130, and 130 control device of safety governor module stops and passes through safe input and output
The enabling information of glove box door 210 is fed back to upper computer module 310 by module 140, the instruction of upper computer module 310 alarm from
And operating personnel's glove box door 210 is prompted to open.Preferably, it can be provided when receiving the alarm of the opening of glove box door 210,
Operating personnel need to release alarm manually.In addition, in the present embodiment, stop when glove box door 210 is opened, refer to this
In the case of 130 commands relays 240 of safety governor module act so that equipment stops, such as utilizes the dynamic of relay 240
Make, the solenoid valve of control shaping intracavity gas disengaging is closed so as to which arrestment vacuumizes；Or utilize the dynamic of relay 240
Make, stop motor shaft so that equipment downtime, stopping print job.
In the present embodiment, the type of alarm opened on glove box door 210 for example can be alarm lamp blinking light
The modes such as alarm, display screen picture prompting alarm, audible alarm.This alarm can be real using existing common alarm module
It is existing, belong to common knowledge, this kind of alarm module known to those skilled in the art, thus do not repeat herein.
The purpose of present embodiment is in the maloperation opened the door in the equipment course of work is prevented, thus in described above
Mainly for equipment printing, chamber door is shaped in vacuum, the opening door operation of glove box door illustrates.
As described above, the enabling control system of the metal molten increasing material manufacturing equipment of present embodiment, it can avoid setting
