The blocking rod 10 is not aligned with the center line of the channel but is biased to one side of the center line of the channel, so that when the blocking rod 10 is ejected downwards, the blocking rod 10 is inserted into the space between two tablets, and the adjacent tablets are prevented from being separated.

1 below of carousel be equipped with a horizontally fixed plate 15, install a vertical pivot 16 on the

fixed plate

15, 16 upper ends of pivot are installed in the centre of a circle department of carousel 1 through feather key slidable, the upper surface circumference equipartition of fixed plate 15 has a plurality of radial protruding strips 17, the lower surface circumference equipartition of carousel 1 has a plurality of vertical bracing pieces 18, the lower extreme of bracing piece 18 supports on fixed plate 15, when pivot 16 drives carousel 1 and rotates, the lower extreme of montant can make carousel 1 vibrate from top to bottom when protruding strips 17, help the tablet on the carousel 1 to disperse and open, avoid piling up in passageway department and block up the passageway.

The upper end and the lower end of the rotating shaft 16 are provided with a first gear 19, the driving motor 13 is fixed on the lower surface of the fixing plate 15, the driving motor 13 is connected with a second gear 20, and the second gear 20 is meshed with the first gear 19, so that the rotating shaft 16 and the rotating disc 1 are driven to rotate.

The bottom surface of the sinking groove 2 is higher than the bottom surface of the radial groove 3, so that the tablets in the sinking groove 2 can smoothly enter the radial groove 3.

The outer end of each radial groove 3 is provided with a receiving box 21 fixed on the side wall of the turntable 1 and used for receiving tablets falling in the sub-packaging grooves 4, the bottom of the receiving box 21 is provided with a medicine outlet, and a pull-out baffle is arranged on the medicine outlet.

1 below circumference equipartition have a plurality of fixed box 22 of keeping in, a partial shipment work is accomplished the back, but accept the tablet in the box 21 one-to-one and fall into the box 22 of keeping in, carousel 1 can carry out the next partial shipment immediately, packs the tablet in the box 22 of keeping in 1 partial shipment of carousel.

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

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

when the rotary table 1 is not started, under the action of the tension spring 6, the vertical plate 5 is positioned at the innermost end, the channel below the vertical plate 5 is the smallest at the moment, the electromagnet 12 is in an electrified state at the moment, and the stop lever 10 is absorbed by the electromagnet 12 and retracted into the sleeve 9.

The invention has total and divide two modes, when dividing and packing under the divide mode, presume the target number value of the display 8 of the divide count at first, then pour the tablet to be divided into in sinking the trough 2, then start the driving motor 13, the driving motor 13 drives the rotary table 1 to rotate through the second gear 20, first gear 19 and spindle 16, and the driving motor 13 accelerates continuously, after the rotary table 1 rotates, a plurality of risers 5 receive the effect of centrifugal force to move outwards, the tension spring 6 stretches, the faster the rotational speed of the rotary table 1, the more outside the position of the riser 5, meanwhile, the tablet in sinking the trough 2 falls into a plurality of radial grooves 3 and locates at the inside of the riser 5 under the effect of centrifugal force, when the riser 5 is close to the inner end, the width of the channel is smaller than the diameter of the tablet, the tablet can's unable to pass through in the channel, when the riser 5 moves outside to the width of the channel is equal to or slightly greater than the diameter of the tablet, the tablet falls into the sub-packing trough 4 and passes to the riser 5 from the channel, after the counting sensor 7 detects that the first tablet passes through, the counting sensor sends a control signal to the driving motor 13 to enable the driving motor 13 to no longer accelerate, and the driving motor rotates at a constant speed at the current speed, so that the vertical plates 5 are stabilized at the current position under the action of centrifugal force and tension of the tension spring 6, and the tablets sequentially pass through the channel under the action of the centrifugal force and fall into the receiving box 21 from the outer end of the split charging groove 4.

When the numerical value of the sub-counting display 8 of a certain subpackaging unit reaches a set numerical value, the counting sensor 7 sends a control signal to the electromagnet 12 of the group to power off the electromagnet 12, the stop lever 10 of the group pops downwards under the action of the pressure spring 11 to cut off a channel, so that subsequent tablets cannot continuously pass through the channel, when all the numerical values of the sub-counting display 8 reach the set numerical value, the subpackaging operation is completed, the driving motor 13 stops, the baffle of the receiving box 21 is opened at the moment, the tablets in the receiving box 21 fall into the temporary storage box 22 below, then the driving motor 13 is started to subpackage next time after the tablets are poured into the sinking groove 2, and the temporarily stored and the tablets in the sinking groove are packaged at the same time; packaging for several times to obtain the required dosage.

In some cases, the medicines taken by the patient are single, each patient does not need to be packaged separately, the medicines are packaged together after the total amount is enough, and the patient takes the medicines for each patient, so that the total mode is used; under total mode, a plurality of numbers that divide count display 8 are gathered by total count display 23, divide count display 8 no longer to set up target value, total count display 23 sets up total amount target value, after total count display 23's numerical value reached total target value, a plurality of electro-magnets 12 cut off the power supply simultaneously, a plurality of passageways are no longer through the tablet, then driving motor 13 shuts down, it can to collect the packing with the tablet in a plurality of take-up boxes 21.

When the rotary table 1 rotates, the supporting rod 18 on the lower surface of the rotary table 1 drives the rotary table 1 to vibrate up and down under the action of the convex strip 17 on the fixing plate 15, so that tablets can be dispersed and smoothly pass through the channel, and the tablets are prevented from being accumulated.

After the partial shipment is accomplished, if heavy groove 2 and partial shipment 4 interior remaining tablet are more, then start driving motor 13 and make the tablet exhaust and retrieve, if remaining tablet is less, then directly collect with tweezers and retrieve can.

The subpackage units are six groups in proper quantity, so that the dosage of two days or three days can be obtained exactly after each subpackage, the efficiency is guaranteed, and certain flexibility is realized.

The control relation between count sensor 7, count display, electro-magnet 12 and driving motor 13 is accomplished by PLC, and this is conventional prior art, and this application is not repeated.

The invention has the following remarkable technical effects: firstly, the invention can rapidly subpackage the dosage for many times, greatly improves the working efficiency of medicine taking, and is particularly suitable for patients with large dosage taken at one time; secondly, the invention can be matched with the trapezoidal split charging groove 4 through the centrifugal motion of the vertical plate 5, can automatically adapt to tablets with various diameters, does not need manual adjustment, and has strong universality; furthermore, the invention can avoid counting error and improve the accuracy of tablet split charging by the offset of the counting sensor 7.
