Description
Technical field
The present invention relates to a kind of control device possessing the injection (mo(u)lding) machine of the abnormity detection portion of the abnormality detecting injection (mo(u)lding) machine.
Background technology
In injection (mo(u)lding) machine, combined by the tail plank of stationary platen with the behind being configured in movable platen by multiple connecting rod, movable platen and tail plank move along connecting rod.In addition, the mutually relative die mounting surface of stationary platen with movable platen is separately installed with mould, carries out die sinking and mold closing action.
In addition, make injecting unit relative to stationary platen forward-reverse, the injection nozzle of the cylinder front end of injecting unit is made to be close to the resin injection mouth of the fixed mould be arranged on stationary platen, the resin sending into melting to cylinder front is rotated by screw, screw is advanced mobile, in mould, inject the resin of melting thus.
Fig. 1 is the integrally-built figure representing the injection (mo(u)lding) machine comprising injecting unit, represents that the injection nozzle 12 of the front end in the injection cylinder portion 11 of injection part of sening as an envoy to is close to the state of the resin injection mouth of the fixed side mold 40b be fixed on stationary platen 33.
Injection (mo(u)lding) machine possesses mold closing portion and injection part on pedestal.Injection part carries out heating and melting to resin material (particle), to this molten resin of intracavitary administration of mould 40 (40a, 40b).Mold closing portion mainly carries out the opening and closing of mould 40.
In injection part, injection nozzle 12 is installed in the front end in injection cylinder portion 11, is through with screw 13 in injection cylinder portion 11.In addition, symbol 14 is the funnels supplying resin to injection cylinder portion 11.
Mold closing portion possesses tail plank 31, movable platen 30, the stationary platen 33 be fixed on pedestal.Tail plank 31 and stationary platen 33 are linked by many connecting rods.
In addition, in injection (mo(u)lding) machine, possess and make the elbow-bar mechanism of movable platen 30 forward-reverse, the screw 13 in through injection cylinder portion 11 rotated or the mechanism of forward-reverse, in the driving of these mechanisms, use servomotor 2 respectively.In addition, with each servomotor 2 accordingly, in order to drive servomotor 2 to be provided with servo amplifier 4, coupled together between servomotor 2 and servo amplifier 4 by cable 8.
In addition, Fig. 1 represents the control device of injection (mo(u)lding) machine of the present invention, but structure described above relates to known technology, therefore uses Fig. 1 to be illustrated.
In the control device of injection (mo(u)lding) machine, possess following function, namely detect the exception that each position in injection (mo(u)lding) machine produces, make running stop as required, report abnormality.As the example of abnormality, if detect that then control device makes running stop, and reports exception to operator because products formed shaping in upper one-period remains in the exception caused in mould.In this case, in order to prevent the reduction of the productivity ratio caused because of dwell time, operator's products formed that removing is residual at once usually, removes abnormality and recovers continuous print running (operating continuously).
Injection (mo(u)lding) machine, when carrying out so continuous running, uses sometimes under the condition of over proof high load capacity.Under the condition of such high load capacity, if exceed load and the time of permission, then injection (mo(u)lding) machine uses sometimes servomotor 2, servo amplifier 4, cable 8 etc. cause scaling loss, are therefore detected as the overload exceeding permission abnormal.In this case, the control device of injection (mo(u)lding) machine makes the stopping that operating continuously, reports exception to operator.
In addition, in Japanese Laid-Open Patent Publication 62-321716 publication, disclose following technology, namely as the injection method of motor control of injection (mo(u)lding) machine, differentiate whether the superheat state that the integrated value of the caloric value that the injection motor drive current in 1 injection moulding cycle causes exceedes the permission integrated value of caloric value when flowing through continuous rating electric current such is set up, and carries out predetermined avoidance action when superheat state is set up.
For many exceptions that the control device of injection (mo(u)lding) machine detects, by being removed the exception that control device detects by operator, continuous running can be recovered.But, when overload exception, if immediately recover running continuously, then likely again exceed a reference value of temperature, if repeat such situation, then significantly shorten the life-span of device sometimes.
Fig. 7 is the figure of the relation represented between the running stop conditions of the prior art and motor interior temperature.As shown in Figure 7, by reference value be the value of overload exception representing motor.In addition, if motor interior temperature exceedes a reference value because motor becomes overload exception, then detect this situation according to control device and be judged as exception, shutting down.But, if remove abnormal and recover running in short time, remove even if then abnormal, produce the heat of scheduled volume due to the driving of motor, therefore can exceed a reference value and shut down.
If recover running continuously like this under the state that heat radiation is insufficient, then again detect that overload is abnormal sometimes, be therefore sometimes difficult to find the suitable condition of molding that can operate continuously.In order to solve it, also can use specified larger drive unit, but in this case, larger-scale unit, price also uprises sometimes thus.
In addition, the integrated value of the caloric value calculated according to the drive current of injection motor and permissible value compare and differentiate by the technology disclosed in Japanese Laid-Open Patent Publication 62-321716 publication, therefore sometimes become the result that deviate from actual overheated value due to other factors beyond drive current.
