The iron ball of three kinds of specifications is stored in ball storehouse 12 and third ball cabinet 13 respectively, wherein the first ball cabinet 11,12 and of the second ball cabinet
Third ball cabinet 13 is respectively big ball storehouse, middle ball storehouse and small ball storehouse, and the quality of iron ball is successively in big ball storehouse, middle ball storehouse and small ball storehouse
Reduce；
Ball grasping device 2 grabs bulb equipped with liftable, and ball grasping device 2 can be respectively by the first storage by controller control
It is put into the iron ball feeding inlet 3 of milling apparatus, grabs after iron ball crawl in ball storehouse 11, the second ball cabinet 12 and third ball cabinet 13
The weighing device that can be detected to the weight of crawl steel ball is additionally provided on ball device 2, the weighing device is weighing sensor,
Weighing sensor is electrically connected with the controller；
The ball-grinding machine ball adding device grab ball control method the following steps are included:
A, parameter setting, in the controller setting need to grab the total weight of ball, the ratio of three kinds of specification iron balls, the ball adding class time and
Ball adding cycle time, wherein class's time is made of multiple cycle times, meanwhile, controller calculates averagely every automatically
The weight capacity value of three kinds of specification iron balls in a cycle time；
B, ball is grabbed in starting, resets board, is grabbed ball device 2 and is started automatically, and controller control grabs ball device 2 within a cycle time
The iron ball of three kinds of specifications is grabbed respectively, and is put into the iron ball feeding inlet 3 of milling apparatus, during this cycle time, controller pair
The weight of every kind of specification iron ball of crawl carries out cumulative calculation, up to the cumulative calculation weight of three kinds of specification iron balls in the cycle time
Magnitude is all larger than or equal to when the weight capacity value of three kinds of specification iron balls, stopping grabbing ball in the cycle time in cycle time,
And it waits until repeating in cycle time after the arrival of next cycle time and grabbing ball operation.
C, terminating ball adding, controller carries out cumulative statistics to the weight value grabbed in the iron ball of every kind of specification all periods,
When the weight of cumulative statistics is greater than or equal to total weight, terminate ball adding operation.
Further, the cumulative calculation weight of certain specification iron ball is greater than the specification iron in cycle time in the step b
When the weight capacity value of ball, subtracted in the weight capacity value of the specification iron ball greater than part within the cycle time in next period
Weight value, is unable to control due to grabbing the weight that bulb grabs every time and (can grab one, two iron ball etc. more), will cause each period knot
The cumulative calculation weight value of iron ball can generate one beyond the weight capacity value of period iron ball and have more surplus when beam, and controller will be
Next cycle will have more surplus automatically and cut, and can reduce the error of final cumulative amount in this way.
Grab ball control method in a preferred embodiment the following steps are included:
A`, parameter setting, set in the controller need to grab the total weight of ball as the ratio of 200kg, bead, middle ball, big ball be 2:
2:1, i.e. bead are 80kg, middle ball is 80kg, big ball 40kg, and the ball adding class time is 2.5 hours, and ball adding cycle time is 30 points
Clock, wherein class's time is made of 5 cycle times, meanwhile, controller calculates three kinds of rule in averagely each cycle time automatically
The weight capacity value of lattice iron ball, wherein the weight capacity value in bead each period is 16kg, the weight capacity in middle ball each period
Value is 16kg, and the weight capacity value in big ball each period is 8kg；
Ball is grabbed in b`, starting, resets board, is grabbed ball device 2 and is started automatically, and controller control grabs ball device 2 in a cycle
The interior successive crawl for carrying out three kinds of bead, middle ball and big ball specification iron balls, and the iron ball of crawl is put into the iron of milling apparatus
In ball feeding inlet 3, when grabbing bead, the bead for grabbing 2 pairs of ball device crawls is weighed, and sends weight value to control
Device, controller add up weight value, form the period cumulative calculation weight value of bead, when the period cumulative calculation weight of bead
When magnitude is greater than or equal to weight capacity value (i.e. the 80kg) of bead in cycle time, stop bead in the cycle time grabs ball
Operation；In crawl when ball, the middle ball for grabbing 2 pairs of ball device crawls is weighed, and sends weight value to controller, controller
Weight value is added up, the period cumulative calculation weight value of ball in formation, the period cumulative calculation weight value of ball is greater than in the middle
Or equal to ball middle in cycle time weight capacity value (i.e. 80kg) when, stop middle ball in the cycle time grabs ball operation；?
When grabbing big ball, the big ball for grabbing 2 pairs of ball device crawls is weighed, and sends weight value to controller, and controller is to weight
Value is added up, and the period cumulative calculation weight value of big ball is formed, when the period cumulative calculation weight value of big ball is greater than or equal to
In cycle time when weight capacity value (i.e. the 40kg) of big ball, stop middle ball in the cycle time grabs ball operation；It is large, medium and small
The cumulative calculation weight value of three kinds of specification iron balls is all larger than or equal in cycle time when the weight capacity value of three kinds of specification iron balls,
Stop the ball of grabbing in the cycle time, and waits until repeating in cycle time after the arrival of next cycle time and grabbing ball
Operation；
C`, terminate ball adding, controller carries out cumulative statistics to the weight value grabbed in the iron ball of every kind of specification all periods, when tired
When the weight of meter statistics is greater than or equal to total weight, terminate ball adding operation.
