Embodiment
Below in conjunction with accompanying drawing, the utility model is done to describe further through embodiment.
Embodiment:
Referring to Fig. 1, Fig. 2 and Fig. 3, the automatic charge weighing apparatus with automatic calibrating device comprises frame 1, feeding mechanism 4, weigh tube 9 and discharge bucket 3; The exit of discharge bucket 3 is separately installed with bag inserting machine structure 12 and coder 13.Frame 1 middle part one side is equipped with controls display 2, and opposite side is equipped with conditioning subassembly 11, on the upper stand of the tube 9 of weighing sensor 5 is installed;
The both sides, tube 9 outside below of weighing are separately installed with calibrating platform, and are respectively equipped with clamping device 7 on the corresponding frame of both sides calibrating platform; Referring to Fig. 4, Fig. 5 and Fig. 6; Clamping device 7 comprises the fixed mount 15 that is installed on the frame; Fixed mount 15 is triangular in shape, and fixed mount 15 end faces are uniformly distributed with the top that 17, four guide pillars 17 of four guide pillars are installed and through fixed head 18 lift cylinder 21 are installed; The piston rod of lift cylinder 21 extends fixed head 18 bottoms, and the piston rod of lift cylinder 21 is connecting clamping limb plate 19.Clamping limb plate 19 is connecting clamping base plate 22, and gripper cylinder 16 is installed on clamping base plate 22 1 sides outside through air cylinder fixed plate 28; One cavity is arranged at clamping base plate 22 tops; The tailpiece of the piston rod of gripper cylinder 16 is positioned at the cavity of clamping base plate 22; The tailpiece of the piston rod of gripper cylinder 16 is flexibly connecting clamping limb 20 through sliding pin 25 respectively through the other end that push pedal 29 is flexibly connecting 26, two short connecting rods 26 of two short connecting rods; Each clamping limb 20 is L shaped; Its corner is installed in the cavity of clamping base plate 22 through fixed pin 24; The other end of each clamping limb 20 is overhanging, and counterweight 8 in the clamping of filling the span of a man's arms of the corresponding shape of filling the span of a man's arms that is of the overhanging end of two clamping limbs 20, the overhanging end of two clamping limbs 20; The below of two counterweights 8 corresponding respectively the calibrating platform of the both sides, tube 9 outside below of weighing.
Principle of work is following: when the weighing apparatus weighing sent overproof warning, PLC sent instruction and stops charging for feeding mechanism 4, empties the material in the tube 9 of weighing simultaneously, and and then PLC sends the target component of revising in the batching controller.When target component reaches requirements; Lift cylinder 21 in the clamping device 7 promotes clamping limb plate 19, and sandwich arm plate 19 falls to counterweight 8 being put on the calibrating platform of the tube 9 outside belows of weighing along guide pillar 17, and the piston rod of gripper cylinder 16 promotes short connecting rod 26 simultaneously; Short connecting rod 26 promotes clamping limb 20; Clamping limb 20 around fixed pin 24 to both sides rotation unclamp counterweight 8, when batching controller batching etc. stops to glimmer, demarcate success, PLC sends and confirms instruction.Then gripper cylinder 16 shrinks and drives short connecting rod 26, and short connecting rod 26 drives clamping limb 20, and clamping limb 20 centers on inwardly rotation clamping counterweight 8 of fixed pin 24, and lift cylinder 21 shrinks simultaneously, promotes whole clamping limb plate 19, and the tube 9 of weighing is left in counterweight 8 liftings.So just accomplish the operation of Zero positioning, can repeat top process if demarcate unsuccessful total system, till demarcating successfully.
