The specific embodiment
Below in conjunction with accompanying drawing die casting machine protective door control system and the die casting machine protective door system that the utility model provides is described in further detail.
As shown in Figure 1, the die casting machine protective door control system die casting machine protective door control system that the utility model provides, this control system comprises interconnective door controller 10 and electric machine controller 20, this control system also comprises pressure-detecting device 30, and described pressure-detecting device 30 links to each other with door controller 10.
Described pressure-detecting device 30 links to each other with door controller 10, for being used for detecting protective door opening or closing the pressure detecting element whether closed procedure is squeezed, for example can be touch sensor.The built-in some pressure sensing elements of touch sensor, when being subjected to the external force extruding, described pressure sensing element can send the signal of expression pressurized to door controller 10, and door controller 10 is controlled the protective door phase down according to this signal and is opened with reference speed.Described reference speed can set up on their own as required, and generally, described reference speed is slow than protective door open and close speed.The shell of described touch sensor is enclosed with pressure buffer element, for example rubber, and rubber has stronger pressure buffer effect, can avoid the people to be subjected to the bump injury.
Described pressure-detecting device 30 can be distributed on the protective door for one or more, is preferably a plurality ofly, can detect in a plurality of positions like this.
Because die casting machine protective door control system is in control protective door open and close process, the opening and closing speed of protective door normally fixing and inflexibility, the stationarity of motion is relatively poor.In order to realize the steady switching of protective door, under the preferable case, the die casting machine protective door control system that the utility model provides also comprises door position detecting device 23, and this door position detecting device 23 links to each other with door controller 10.
As shown in Figure 2, described door position detecting device 23 accurately detects for the current opened and closed positions that is used for opposite house, thereby realizes the accurately position detection device of control of protective door opening and closing speed, for example can be photoelectric encoder.
Photoelectric encoder is a kind of high-precision sensor that the geometry of machinery displacement is converted to pulse or digital quantity by opto-electronic conversion, reflect current motor speed by the number of calculating the output pulse, can control the switching stroke of protective door exactly, its operation principle is conventionally known to one of skill in the art.And photoelectric encoder can constitute the closed-loop control system that protective door opens and closes by the feedback to the current opened and closed positions of protective door, acceleration and deceleration to protective door are controlled, for example control is quickened in the switching of protective door at the protective door initial stage that opens and closes, open and close latter stage to the switching of the protective door control of slowing down at protective door, the flexibility that realizes protective door opens and closes, and guarantees the stationarity that protective door opens and closes.
In order to judge whether complete opening or close fully of protective door, under the preferable case, the die casting machine protective door control system that the utility model provides also comprises a condition checkout gear 41, and described door condition checkout gear 41 links to each other with described door controller 10.
As shown in Figure 2, described door condition checkout gear 41 is used to judge whether complete opening or close fully of protective door, and will represent the protective door complete opening or the protective door status signal of closing fully sends to door controller 10, so that door controller 10 is made corresponding response according to the protective door status signal that receives.Under the preferable case, described door condition checkout gear 41 is untouchable magnetic switch.Utilize the sensing capabilities of non-contact type magnetic switch to respond to the opening and closing of protective door, and send corresponding signal, for conventionally known to one of skill in the art.When door condition checkout gear 41 is output as the status signal of " ON " and the current location by door position probing 23 record show gates for " 0 ", door condition checkout gear 41 judges that protective doors are in complete opening or closing state fully, and will represent the protective door complete opening or the protective door status signal of closing fully sends to door controller 10.And when door condition checkout gear 41 is output as the status signal of " OFF " or the current location by door position probing 23 record show gates for " 0 ", door condition checkout gear 41 judges that protective door is in not complete opening or complete closing state, does not send and represents that protective door complete opening or the protective door status signal of closing fully send to door controller 10.
Door condition checkout gear 41 is because self-defect or outside cause are lost security function when causing disabler (as the weldering of Chu Dian Rong, electric short circuit or open circuit etc.) easily; therefore; under the preferable case; in order to improve the protective door safety coefficient; this die casting machine protective door control system also comprises safety guard 40; described door condition checkout gear 41 links to each other with door controller 10 by safety guard 40, outputs to gate control 10 from the signal of the expression protective door state of door condition checkout gear 41 by described safety guard 40.
