Press such scheme, described executing agency also is included in the accurate guard's valve that guide rail arranges corresponding below feed hopper on the way, is used for the accurate location of feeding cart.
Press such scheme, described executing agency also comprises emergency stop switch and the collision energy-absorbing device that is separately positioned on the guide rail two ends.
A kind of injection workshop of concentrating feeding system to realize based on above-mentioned injection workshop is concentrated the feeding system control method, it is characterized in that:
Controller is according to the accurate location of Charge level measurer real-time detecting material tank Raw, and according to the start and stop of material level information control charging equipment;
When the scarce material detector in the feeding cart detected feeding cart and lacks material, suction feeder was opened material sucking port under the control of controller, drew raw material in the storage tank to feeding cart, this moment the feeding cart bottom closed electromagnetic valve; After the detection of the weight tester in the feeding cart reached needed material loading weight, suction feeder was closed, and stops suction, and feeding cart moves to the feed hopper top of appointment, and magnetic valve is opened, and raw material is down in the feed hopper by gravity; After discharging was complete, it was the suction feeder below that closed electromagnetic valve, feeding cart move to the position that connects material, and finishes a feed cycle;
Before material loading next time, magnetic valve is opened, and with the air blast of feeding cart top feeding cart inside is purged; When injection machine reloads, before material loading next time, with the air blast in the feed hopper feed hopper inside is purged.
Press such scheme, controller is accurately located feeding cart by the accurate guard's valve of feed hopper below at guide rail correspondence being set on the way.
Press such scheme, when feeding cart ran to the guide rail two ends, controller stopped by emergency stop switch control feeding cart, and by collision energy-absorbing device feeding cart is carried out urgency and stop buffering.
Beneficial effect of the present invention is:
1, by adopting system of the present invention and control method, design large-scale storage tank and corresponding batch can charging equipment and can guarantee uninterrupted materials and saving human cost in the production process, reduce the plane space that storage takies, and avoid owing to exposing to the sun and rain that air storage causes; By design guide rail and movable loading dolly, the feed hopper of injection machine is together placed side by side, can produce simultaneously for many injection machines in the workshop; May change according to the needed raw material of production schedule injection machine, therefore can connect material to the position that connects material according to the material list of production schedule regulation, connect material complete after, move quickly into corresponding injection machine feed hopper top, plastic raw materials is discharged in the feed hopper, forms automation and intelligentized conveying system; Adopt the purging system that reloads between cycle at feed, guarantee that raw material without mutual doping, avoids affecting the surface quality of moulding.
2, in order to guarantee that feeding cart can be parked on the corresponding feed hopper accurately, the accurate guard's valve of feed hopper and controlled by controller below guide rail arranges correspondence on the way.
3, design respectively an emergency stop switch at the guide rail two ends, can prevent that feeding cart from going out guide rail in unexpected situation, collision energy-absorbing device stops providing buffering to feeding cart is anxious.
