In design, two rest shoe current potentials are not waited.Because being grabbed part (filter case) is electric conductor, when grabbing the part success, two rest shoe current potentials equate that when grabbing the part failure, two rest shoes still keep the unequal state of current potential.So when grabbing part, whether successfully whether control system just can equate according to the current potential of two rest shoes to judge grabs part.Judge and to grab part whether successful meaning is: when grabbing part when getting nowhere, possibility greatly is that the be not stretched liftout tank of machine of tensioning member ejects mould, that is to say that tensioning member is stuck in mould,, drawing die is damaged at this moment as continuing to send virgin material to stretch.So whether with grabbing part successfully is to judge whether tensioning member is stuck in the mould, determines whether continue the unique foundation of new one-off drawing, so this technology plays the supervision effect to mould protection.
The course of work of the present invention following (in conjunction with Fig. 3, Fig. 4):
1, initialization
After respectively with compressed air, power connection, each one of manipulator is in init state, that is: arm cylinder retraction; Metacarpus falls; Chela unclamps.And prompting: reclaimer is ready, waits for, waits until that always stretching-machine starts, and feeding begins to draw.
2, the course of work
When plate is sent in the stretching-machine mould and during by stretching-machine stretch forming, the up arrival top dead centre of stretching-machine slide block band mould, the liftout tank of stretching-machine ejects counterdie with tensioning member, meanwhile the tablet of stretching-machine also arrives slider position sensor KHS, (KHS is installed on the top dead centre of stretching-machine slide block) with the slide block rising.This moment, KHS sender notice mechanical arm stretched out, mechanical arm is under the effect of arm cylinder, shoot out, when mechanical arm stretches out when putting in place, the center of two rest shoes just in time with wait to grab tensioning member identical (adjusting the front end stop), this moment arm extended position sensor KZC sender, the notice claw can be grabbed part, grab the part cylinder and drive tongue piece retraction, tong arm and rest shoe shrink under the pulling force effect of extension spring, and rest shoe will wait that grabbing part tightly clamps, this moment circuit whether will inquire about two rest shoe current potentials equal, as equating, be called to grab the part success, (grabbing the unsuccessful aftermentioned of part).When grabbing part cylinder retraction when putting in place, grab part sensor KZJ sender, notice palm branch lifts, and the tensioning member that palm branch drives tong arm under the effect of palm cylinder, firmly grasped by rest shoe lifts the 25mm height, make the tensioning member bottom thoroughly leave mould, for tensioning member safety is taken away ready.After metacarpus lifts, sensor KZT sender on the palm cylinder, notice mechanical arm retraction, mechanical arm bounces back rapidly under the effect of arm cylinder and puts in place, the tensioning member that clamped by tong arm, rest shoe this moment just in time is in the top (adjusting the rear portion stop) of the conveyer belt that connects material, be in the position sensor KZS sender at arm cylinder rear portion simultaneously, a: the notice feeder send virgin material, start that slide block and mould are descending to carry out new one-off drawing process, b: the notice metacarpus falls, tong arm unclamps, at this moment tensioning member will drop on the conveyer belt, deliver to subsequent processing by conveyer belt.Reclaimer so far has been finished one and has been got the material cycle, and this moment, the state of each one of manipulator was identical with init state.After every this new stretching was finished, manipulator all will reach the purpose of constantly getting material from multiple above-mentioned action at every turn.
When pickup is unsuccessful, two rest shoe current potentials are unequal, and circuit control system judges that tensioning member is stuck in the mould, and at this moment control system is interrupted normal work tempo at once, the arm cylinder of issuing an order bounces back, shuts the gate of feeder, stretching-machine slide block down immediately, whole production line quits work, and alarm, waits the Hou personnel to fix a breakdown, after fault is got rid of, operating personnel click and reset strongly, and each one of manipulator is from newly being in init state, and whole system can rerun.
More than orderly action be under the monitoring of control circuit, to finish, this circuit adopts digital integrated electronic circuit as core component, circuit has that volume is little, reliability is high, the life-span is long, be convenient to characteristics such as maintenance.(circuit theory narration: slightly).
