The bottom of the receiving box 21 is provided with a medicine discharge. The medicine outlet is equipped with a pull-out baffle.

A plurality of fixed temporary storage boxes 22 are evenly distributed around the lower part of the turntable 1. After the completion of one sub-packing, the tablets in the receiving box 21 can be dropped into the temporary storage boxes 22 one by one, and the turntable 1 can be loaded immediately. In the second sub-packaging, the tablets in the temporary storage box 22 are packaged while the turntable 1 is sub-packed.

Also included is a total count display 23 that summarizes the sum of the counts of all sub-count displays 8 .

The working process and principle of the present invention are as follows:

When the turntable 1 is not started, under the action of the tension spring 6, the vertical plate 5 is located at the innermost end, and the channel below the vertical plate 5 is the smallest. retract into the sleeve 9 .

The present invention has two modes of totalization and sub-counting. In the sub-counting mode, the target value of the sub-count display 8 is firstly set, and then the tablets to be sub-packaged are poured into the sink 2, and then the driving motor is started. 13. The drive motor 13 drives the turntable 1 to rotate through the second gear 20, the first gear 19 and the rotating shaft 16, and the drive motor 13 continues to accelerate. After the turntable 1 rotates, the plurality of vertical plates 5 are moved outward by the action of centrifugal force, and the tension springs 6. Stretch, the faster the rotating speed of the turntable 1, the further the position of the vertical plate 5 is. At the same time, the tablets in the sinking groove 2 fall into the plurality of radial grooves 3 under the action of centrifugal force and are located on the inner side of the vertical plate 5. 5. When approaching the inner end, the width of the channel is smaller than the diameter of the tablet, and the tablet cannot pass through the channel. When the vertical plate 5 moves outward to the width of the channel that is equal to or slightly larger than the diameter of the tablet, the tablet falls into the dispensing slot 4 and passes through the channel. Pass through the passage to the outside of the vertical plate 5. After the counting sensor 7 detects the passage of the first tablet, it sends a control signal to the drive motor 13 to stop the drive motor 13 from accelerating and rotate at a constant speed at the current speed. Under the action of centrifugal force and the pulling force of the tension spring 6 , the tablet is stabilized at the current position, and the tablet passes through the passage in turn under the action of centrifugal force, and falls into the receiving box 21 from the outer end of the dispensing slot 4 .

When the value of the sub-counter display 8 of a certain sub-packaging unit reaches the set value, the counting sensor 7 will send a control signal to the electromagnet 12 of the group to turn off the electromagnet 12. Under the action of the compression spring 11, the The blocking lever 10 of the group pops down to cut off the channel, so that subsequent tablets cannot continue to pass through the channel. When the values of all the sub-counter displays 8 reach the set value, the sub-packaging operation is completed, and the drive motor 13 stops. At this time Open the baffle of the receiving box 21, the tablets in the receiving box 21 fall into the temporary storage box 22 below, and then pour the tablets into the sink 2 and start the drive motor 13 for the next sub-packaging. Pack the stored and stored tablets; after multiple dispensing, the required amount of medicine is obtained.

In some cases, the medicines taken by the patient are relatively single, and each meal does not need to be packaged separately, but only needs to be counted and then packed together. The patient counts the medicines for each meal and takes the medicine by himself, then the total mode is used at this time; in the total mode , the numerical value of a plurality of sub-count displays 8 is summarized by the total-count display 23, the sub-count display 8 no longer sets the target value, the total-count display 23 sets the total-target value, and when the value of the total-count display 23 reaches the total target value, more Each electromagnet 12 is powered off at the same time, and multiple channels no longer pass the tablets, then the driving motor 13 stops, and the tablets in the multiple receiving boxes 21 can be collected and packaged.

When the turntable 1 rotates, the support rods 18 on the lower surface of the turntable 1 drive the turntable 1 to vibrate up and down under the action of the raised strips 17 on the fixed plate 15, which helps the tablets to be dispersed and smoothly pass through the channel and avoid the accumulation of the tablets.

After the sub-packaging is completed, if there are many tablets remaining in the sink tank 2 and the sub-packaging tank 4, the driving motor 13 is started to discharge the tablets for recovery.

The appropriate number of the sub-packaging units is six groups, so that after each sub-packaging, two or three days' doses of medicine are obtained, which not only ensures the efficiency, but also has a certain flexibility.

The control relationship among the counting sensor 7 , the counting display, the electromagnet 12 and the driving motor 13 is completed by PLC, which is a conventional prior art and will not be described in detail in this application.

The present invention has the following significant technical effects: firstly, the present invention can quickly dispense multiple doses of medicine, greatly improve the working efficiency of dispensing medicine, and is especially suitable for patients with a large amount of medicine for single dispensing; secondly, the present invention The centrifugal motion of the vertical plate 5 can cooperate with the trapezoidal dispensing groove 4, and can automatically adapt to tablets of various diameters, without manual adjustment, and has strong versatility; Counting errors improve the accuracy of tablet dispensing.
