By such scheme, described executing agency is also included in the accurate guard's valve that guide rail arranges corresponding below feed hopper on the way, for the accurate location of feeding cart.
By such scheme, described executing agency also comprises the emergency stop switch and collision energy-absorbing device that are separately positioned on guide rail two ends.
The injection workshop concentrating feeding system to realize based on above-mentioned injection workshop concentrates a feeding system control method, it is characterized in that:
Controller according to the accurate location of Charge level measurer real-time detecting material tank Raw, and controls the start and stop of charging equipment according to material level information;
When the scarce material detector in feeding cart detect feeding cart lack material time, suction feeder opens material sucking port under the control of the controller, draws raw material in storage tank in feeding cart, the closed electromagnetic valve now bottom feeding cart; After the weight tester in feeding cart detects and reaches required material loading weight, suction feeder is closed, and stops suction, and feeding cart moves to above the feed hopper of specifying, and magnetic valve is opened, and raw material is down in feed hopper by gravity; After discharging, closed electromagnetic valve, feeding cart moves to below filling position and suction feeder, completes a feed cycle;
Before upper once material loading, magnetic valve is opened, and purges feeding cart inside with the air blast above feeding cart; When injection machine reloads, before upper once material loading, with the air blast in feed hopper, feed hopper inside is purged.
By such scheme, controller is accurately located feeding cart by the accurate guard's valve arranging corresponding below feed hopper at guide rail on the way.
By such scheme, when feeding cart runs to guide rail two ends, controller by emergency stop switch control feeding cart stop, and by collision energy-absorbing device to feeding cart carry out urgency stop cushion.
Beneficial effect of the present invention is:
1, by adopting present system and control method, design large-scale storage tank and corresponding batch can charging equipment can guarantee uninterrupted materials and saving human cost in production process, reduce and store the plane space that takies, and exposing to the sun and rain of avoiding causing due to air storage; By design guide rail and movable loading dolly, by together placed side by side for the feed hopper of injection machine, can produce for multiple stage injection machine in workshop simultaneously; Raw material required for production schedule injection machine may change, the material list that therefore can specify according to the production schedule carries out splicing to splicing position, after splicing, move quickly into above corresponding injection machine feed hopper, plastic raw materials is discharged in feed hopper, forms automation and intelligentized conveying system; Between the feed cycle, adopt the purging system that reloads, guarantee that raw material is without mutual doping, avoids the surface quality affecting moulding.
2, in order to ensure that feeding cart can be parked on corresponding feed hopper accurately, the accurate guard's valve of corresponding below feed hopper is set on the way at guide rail and is controlled by controller.
3, design an emergency stop switch respectively at guide rail two ends, can prevent feeding cart under fortuitous event, going out guide rail, collision energy-absorbing device stops providing buffering to feeding cart is anxious.
