A method for the weighed bottling of powdered drugs, applied to a control system, said method comprising the following steps A1-A5:
step A1, receiving a medicine outlet task, wherein the medicine outlet task comprises a medicine outlet amount;
step A2, controlling the transfer mechanism 42 to separate a piece of drug-loaded paper from the drug-loaded paper storage device 41 and transfer the drug-loaded paper to the scale 2;
step A3, controlling the storage and separation device 1 to separate out powder medicine with the weight consistent with the medicine output quantity;
step A4, controlling the transfer mechanism 42 to transfer the medicine carrying paper on the scale 2 to the post-processing device 3;
step a5, controlling the folding mechanism 31 of the post-processing device 3 to fold the drug-loaded paper loaded with drugs, collecting the drugs on the drug-loaded paper to the middle part of the drug-loaded paper, and then controlling the pouring mechanism 32 to rotate to pour out the drugs on the drug-loaded paper into the bottle.
The step A3 includes the following steps B1-B5:
step B1, multiplying the medicine output quantity by a preset coefficient to obtain a pre-output medicine quantity, wherein the coefficient is a numerical value which is more than 0.9 and less than 1;
in this step, because for the metering device, the ejection of compact has been just can't withdraw the process, consequently, for preventing to surpass out the medicine volume in the measurement, consequently, carry out the ejection of compact according to the medicine volume of prescribing a contract to the heart of a matter in advance, surpass the medicine volume of prescribing a contract to the heart of a matter when prescribing a contract to the heart of a matter, because there is a buffering difference between medicine volume of prescribing a contract to the heart of a matter and the medicine.
Step B2, calculating a discharge distribution mode according to the numerical value of the pre-discharge amount, wherein the discharge distribution mode comprises discharge tasks distributed to each medicine discharge core rod 13, and the discharge tasks are the number of times of back-and-forth sliding of the medicine discharge core rods 13;
for example, in the present embodiment, four standard medicine output mandrels 13 are included, the medicine output mass of each of the four standard medicine output mandrels 13 is 5mg, 3mg, 1mg, and 0.2mg, and if 20 mg of medicine is to be output, and the preset coefficient is 0.95, the pre-output mass is 19mg, and the discharge tasks allocated to the four standard medicine output mandrels 13 are as follows, the medicine output mandrel 13 with 5mg standard is discharged 3 times, the medicine output mandrel 13 with 3mg standard is discharged 1 time, and the medicine output mandrel 13 with 1mg standard is discharged 1 time.
Step B3, controlling the medicine cabin 12 to rotate, sequentially rotating each medicine outlet core rod 13 with a discharging task to a position opposite to the firing pin 141, and controlling the firing pin assembly 14 to push the medicine outlet core rods 13 to stretch and contract for corresponding times;
step B4, reading the reading of the scale 2, and calculating the difference between the dosage and the reading;
in the above example, when the discharging of the medicine discharging core rods 13 of the three specifications of 5mg, 3mg and 1mg is completed, the discharged amount is weighed as 19.1mg, and the difference between the discharged amount and the reading is 0.9 mg.
And step B5, controlling the medicine outlet core rod 13 with the minimum medicine outlet quantity to perform telescopic movement to discharge the medicine according to the difference, reading the reading of the primary metering scale 2 when the medicine is not discharged once, and calculating a residual difference until the proportion of the residual difference relative to the medicine outlet quantity is smaller than the set proportion.
In the above example, the medicine discharge core rod 13 of 0.2mg standard is controlled to extend and contract a plurality of times, each time, about 0.2mg of medicine is discharged, and if the total medicine discharge dose is 19.72mg after the medicine discharge core rod 13 extends and contracts 3 times, the ratio of the remaining difference to the medicine discharge dose is 1.4% and less than the set ratio of 2%, the discharge is considered to be completed.
Further, the step of controlling the firing pin assembly 14 to push the medicine discharging core rod 13 to stretch comprises the following steps C1-C3:
step C1, controlling the electric push rod 147 to drive the pushing member 142 to feed to the medicine cabin 12, pushing the medicine discharging core rod 13 to make the medicine accommodating groove 131 extend out of the medicine cabin 12, and simultaneously making the pin shaft 144 contact with the vibrating teeth 1451 of the fluted disc 145 close to the medicine cabin 12;
step C2, driving the fluted disc 145 close to the medicine cabin 12 to rotate, and enabling the vibrating teeth 1451 to act on the pin shaft 144, so that the striker 141 vibrates in a reciprocating manner for a plurality of times to drive the medicine core rod 13 to vibrate in a reciprocating manner for a corresponding number of times;
and step C3, controlling the electric push rod 147 to drive the pushing member 142 to move away from the medicine cabin 12, and resetting the medicine core rod 13 under the action of the first spring.
Further, before controlling the electric push rod 147 to drive the pushing member 142 to feed to the medicine compartment 12, the method further includes the following steps: the gear disc 145 far from the medicine compartment 12 is driven to rotate, so that the striker 141 vibrates in a reciprocating manner, the medicine core rod 13 is driven to vibrate in a reciprocating manner, and the medicine accommodating groove 131 vibrates in the medicine compartment 12 in a reciprocating manner.
According to the weighing and bottling system and the weighing and bottling method for the powder medicine, the medicine carrying paper is translated between the weighing scale and the post-processing device through the transfer device, the whole process of automatic medicine discharging, weighing, summarizing and pouring of the powder medicine into a bottle can be realized, manual participation is not needed, the operation efficiency is high, and the damage to a human body caused by dust generated in the medicine discharging and bottling process is avoided.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
