[0034] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0035] The first implementation method:

[0036] Figure 1-6 The invention shows an automatic tablet packaging and filling device with controllable quantity, comprising a support frame 1, a vibrating feeder 2 is fixedly connected to the support frame 1, the vibrating feeder 2 is connected to a powder removal mechanism 4 through a feeding trough 3, a sorting and counting mechanism 5 is installed below the powder removal mechanism 4, and a feeding assembly 6 is installed below the right side of the sorting and counting mechanism 5;

[0037] The powder removal mechanism 4 includes a vertical cylinder 7, a center rod 8 is fixedly connected to the central axis position of the vertical cylinder 7, a spiral sheet 9 nested in the vertical cylinder 7 is fixedly connected to the outside of the center rod 8, the inner wall of the vertical cylinder 7, the outer wall of the center rod 8 and the spiral sheet 9 are surrounded to form a spiral feeding chamber, an air inlet pipe 10 connected to the spiral feeding chamber is fixedly connected to the lower part of the vertical cylinder 7, the air inlet pipe 10 is connected to an external blower, an exhaust pipe 11 connected to the spiral feeding chamber is fixedly connected to the upper part of the vertical cylinder 7, the exhaust pipe 11 is connected to an external negative pressure vacuum cleaner, and the lower part of the vertical cylinder 7 is a conical cylinder with an opening at the lower end;

[0038] The sorting and counting mechanism 5 includes a loading turntable 12 that slides against the lower end of the vertical cylinder 7, and the unloading component 6 is located on the side of the loading turntable 12 away from the vertical cylinder 7. The loading turntable 12 is provided with drop holes 1201 that are equidistantly distributed in a circle and vertically penetrate the loading turntable 12. Both the lower end opening of the vertical cylinder 7 and the upper end opening of the unloading component 6 are arranged in coordination with the drop holes 1201. A loading sheet 14 for sealing the drop holes 1201 is inserted into the drop holes 1201, and the inner end of the loading sheet 14 is connected to a first electric push rod 15 nested in the loading turntable 12; a visual camera 13 is arranged above the loading turntable 12, and the visual camera 13 is arranged in coordination with the drop holes 1201. A waste box arranged opposite to the visual camera 13 is arranged below the loading turntable 12, and the waste box is used to collect broken tablets.

[0039] For details, please refer to Figure 2 and Figure 3 When filling tablets, the following steps are included:

[0040] Step 1: Put the tablet raw material into the vibrating feeder 2, and place the medicine bottle under the feeding assembly 6. Start the vibrating feeder 2, the external blower and the external negative pressure vacuum cleaner through the external controller. The vibrating feeder 2 conveys the tablets one by one through the feeding trough 3 to the spiral feeding chamber of the vertical cylinder 7. The tablets spirally descend along the spiral feeding chamber. At the same time, the airflow generated by the external blower is injected into the spiral feeding chamber from the bottom through the air inlet pipe 10, and forms a spiral airflow spirally upward under the action of the external negative pressure vacuum cleaner and the exhaust pipe 11. The spiral airflow performs reverse spiral spraying on the tablets sliding downward along the spiral feeding chamber;

[0041] Step 2: The tablets passing through the spiral feeding cavity enter the conical cylinder at the lower part of the vertical cylinder 7, slide along the inner wall of the conical cylinder and are discharged from the lower opening. The discharged tablets fall into the feeding hole 1201 of the loading turntable 12 and finally fall on the loading sheet 14. The loading turntable 12 drives the tablets to rotate under the action of the motor connected thereto, so that the feeding hole 1201 loaded with the tablets first rotates to the bottom of the visual camera 13, and the visual camera 13 takes pictures and identifies the tablets.

[0042] Step three, when there are broken tablets, the external controller records the number of broken tablets, and drives the carrier sheet 14 to disengage from the drop hole 1201 through the first electric push rod 15, and the tablets fall into the waste bin below through the drop hole 1201; when the tablets are qualified after inspection, the external controller counts the number of qualified tablets discharged, and the loading turntable 12 drives the qualified tablets to rotate above the discharge component 6, and then drives the carrier sheet 14 to disengage from the drop hole 1201 through the first electric push rod 15, so that the qualified tablets fall into the medicine bottle through the discharge component 6.

[0043] Compared with the traditional tablet filling device, the present invention uses a vertical cylinder 7 with a spiral feeding chamber and an external blower and a negative pressure vacuum cleaner connected to the spiral feeding chamber to make the tablets spirally slide down in the vertical cylinder 7. At the same time, the airflow injected into the spiral feeding chamber by the external blower rises in a spiral manner. The spiral rising airflow is in relative contact with the spirally descending tablets, and the tablets are efficiently sprayed, so that the drug powder adhering to the surface of the tablets is detached and discharged to the outside of the vertical cylinder 7 with the spiral rising airflow, thereby achieving efficient cleaning and external discharge of the powder adhering to the surface of the tablets, overcoming the problems of tablet surface contamination and uneven tablet content, and improving the tablet bottling quality; at the same time, through the loading turntable 12 with a feeding hole 1201, the movable loading sheet 14 and the visual camera 13, the tablets are inspected, counted, sorted and discharged one by one, realizing highly integrated sorting and counting operations.

[0044] See also Figure 2 The feed trough 3 is a strip tube with a rectangular cross section, and is tangentially connected to the vertical cylinder 7. The air inlet pipe 10 is arranged above the conical cylinder, and the air exhaust pipe 11 is arranged above the connecting port between the feed trough 3 and the vertical cylinder 7.

[0045] Specifically, it avoids the interference of airflow on the feeding and discharging of tablets, and reduces the collision damage of tablets in the spiral feeding cavity.

[0046] See also Figure 2 and Figure 6 The loading turntable 12 is a disc-shaped structure, the drop hole 1201 is a vertical circular hole, the lower conical cylinder of the vertical cylinder 7 is in sliding contact with the upper surface of the loading turntable 12, and a motor fixedly connected to the support frame 1 is fixedly connected to the lower center position of the loading turntable 12.

[0047] See also Figure 2 A second visual camera is disposed below the loading turntable 12 and is arranged opposite to the vertical cylinder 7. The second visual camera is arranged opposite to the drop hole 1201. The loading sheet 14 is made of transparent plastic material.

[0048] Specifically, the second visual camera and the visual camera 13 cooperate to perform damage detection on both the front and back sides of the tablet to improve the quality of quality inspection.

[0049] See also Figure 5 The spiral blade 9 is a vertical spiral blade, and its spiral inner wall is fixedly connected to the central rod 8, and its spiral outer wall is fixedly connected to the inner wall of the vertical cylinder 7.

[0050] Second implementation method:

[0051] Figure 6-13 The present invention shows an automatic packaging and filling device for tablets with controllable amounts. Based on the first embodiment, the upper end face of the spiral sheet 9 is fixedly connected with uniformly distributed capillary support rods 901, and the tablets slide on the capillary support rods 901. A plurality of guide blocks 801 uniformly distributed in a spiral are provided in the spiral feeding chamber, and the guide blocks 801 are strip blocks protruding downward.

[0052] For details, please refer to Fig.10 When the spiral airflow spirally rises in the spiral feeding chamber, under the guiding action of the guide block 801, a deflected spraying airflow is generated toward the upper end surface of the spiral sheet 9. After the deflected spraying airflow enters the gap of the capillary support rod 901, it collides with the upper end surface of the spiral sheet 9 and then changes direction for a second time. The secondary deflected airflow sprays the lower surface of the sliding tablet on the capillary support rod 901, further improving the powder cleaning effect on the tablet surface.

[0053] See also Figure 8 and Fig. 9 The guide block 801 is a strip block with an inverted triangle cross section. The guide block 801 is fixedly connected to the center rod 8, and a dust gap is formed between the guide block 801 and the lower end surface of the spiral sheet 9.

[0054] For details, please refer to Fig.10 Under the action of the spiral rising airflow, the powder is carried by the airflow and gathered on the lower end surface of the spiral blade 9. The guide block 801 divides the airflow near the lower end surface of the spiral blade 9. The spiral airflow carrying the powder continues to flow upward along the lower end surface of the spiral blade 9 through the dust gap. The spiral airflow with less powder content continues to blow toward the upper end surface of the spiral blade 9 under the guidance of the guide block 801, thereby improving the spray cleaning effect.

[0055] See also Figure 11-13 The material unloading assembly 6 includes an inner sleeve 16 that slides against the lower end surface of the loading turntable 12, an outer sleeve 18 is sleeved on the outer side of the inner sleeve 16 for sliding connection therewith, the outer sleeve 18 is rotatably sleeved with a lifting seat 19, a rotating motor 20 is fixedly connected to the lifting seat 19, the rotating motor 20 is transmission-connected to the outer sleeve 18 through a transmission gear set, and the lifting seat 19 is connected to a lifting cylinder 21 installed on the support frame 1;

[0056] A cylindrical airbag 22 is nested inside the opening of the lower end of the outer sleeve 18, and the cylindrical airbag 22 is connected to a second electric push rod 23 for driving the contraction thereof. The second electric push rod 23 is fixedly connected to a support plate 24 fixedly connected to the outer sleeve 18, and the support plate 24 is penetrated by a guide piece 25 slidably connected to it, and the guide piece 25 is connected to a third electric push rod 26 arranged parallel to it.

[0057] Specifically, when filling and unloading tablets, first, the lifting cylinder 21 is started to insert the support plate 24 and the guide sheet 25 into the medicine bottle, and then the second electric push rod 23 is started, and the second electric push rod 23 squeezes the cylindrical air bag 22 to seal it; second, the first electric push rod 15 drives the carrier sheet 14 to be withdrawn from the blanking hole 1201, and the tablets fall from the blanking hole 1201 through the inner sleeve 16 and the outer sleeve 18 into the sealed cylindrical air bag 22, and the cylindrical air bag 22 cushions the falling tablets; third, the rotating motor 20 and the third electric push rod 26 are started, so that the guide sheet 25 rotates in a circle in the medicine bottle until the tablets are dropped; fourth, the second electric push rod 23 is started again, so that the cylindrical air bag 22 opens again, and the tablets pass through the cylindrical air bag 22 and slide onto the guide sheet 25, and slide obliquely along the guide sheet 25 to the blanking position in the medicine bottle.

[0058] It should be noted that the rotating motor 20 and the third electric push rod 26 realize the circular rotation and oblique extension and retraction of the guide piece 25, and the lifting seat 19 is driven to move up and down through the lifting cylinder 21. The lifting seat 19 drives the guide piece 25 to change its filling height through the outer sleeve 18 and the support plate 24, that is, circumferential filling and lifting filling are performed during the filling process, so that the tablets fall into the medicine bottle evenly, reducing the collision and mutual friction of the tablets, reducing the collision damage when the tablets fall directly into the medicine bottle, reducing the generation of drug powder, and improving the quality of tablet filling.

[0059] See also Figure 6 and Fig.12 The inner sleeve 16 is in sliding contact with the lower end surface of the loading turntable 12 , and the inner sleeve 16 is fixedly connected to the support frame 1 through the mounting frame 17 .

[0060] Specifically, the inner sleeve 16 and the outer sleeve 18 are used to realize lifting and lowering filling, and the height of the guide sheet 25 is changed according to the filling progress to reduce the mutual collision of the tablets in the medicine bottle.

[0061] See also Fig.12 The guide piece 25 is an inwardly concave arc-shaped piece and is inclined.

[0062] Specifically, the situation where the tablets are separated from the side of the guide sheet 25 during the sliding process is reduced, thereby improving the stability of tablet filling.

[0063] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
