Description

Capsule granule filling system and method for realizing rapid capsule filling using the same

Technical Field

The present invention relates to the technical field of filling particles inside capsules, and in particular to a novel system capable of realizing quantitative and rapid filling of drug particles into capsules, and a method for realizing rapid filling of particles into capsules and quantitative bottling of the filled capsules by using the system, in particular to a capsule particle filling system and a method for realizing rapid capsule filling by using the same.

Background technique

The traditional capsule filling process generally includes multiple steps such as drug crushing, screening, weighing ingredients, granulation (divided into wet granulation and dry granulation), fluidized bed drying, granulation, mixing, empty capsule filling, bottling, etc. Among them, empty capsule filling and bottling after capsule granulation have an important impact on the filling efficiency of the entire process and are also a relatively important part of the entire production process.

At present, capsule filling machines are generally used for filling capsules. Existing capsule filling machines are generally used in health care product factories, small pharmaceutical factories, medical research units, hospital preparation rooms, specialist clinics, pharmacies, tonic health care product stores and other units to achieve capsule filling. For example, in the patent document with patent application number: CN200820165036.5, a granule and powder mixed capsule filling machine is disclosed, and its main structure includes an intermittently moving disc conveyor, and capsule shell molds are equally placed on a circle of the disc conveyor. Around the disc conveyor, there are devices required for each station including a granule feeding device, a powder feeding device, and a detection device, and their working mechanisms are aimed at the position of the capsule shell mold when the disc conveyor stops. The powder feeding device includes a hopper, a cup-type metering mechanism, and a channel for guiding the material in the hopper to the capsule shell position on the disc conveyor through the metering mechanism. Among them, an electric vibrator is installed on the powder feeding device, and there is also an electronic computer, whose signal input end is connected to the electric signal output end of the detection device, and whose signal output end is connected to the control circuit of the electric vibrator.

Combined with the full text of the above patent, it can be seen that a vibrator is installed on the powder feeding device when it is working, so that the powder material is driven by the vibration force during the process of metering and inputting into the capsule shell, the gap between the powder material is reduced, the density is large and consistent, the cup wall is clean and non-sticky when filling into the capsule shell, and the powder material enters the capsule shell and can fill part of the gap with the original granular material. However, this structure can only be used when filling powder into the capsule when realizing the filling of the capsule, and cannot effectively process the previous process of the empty capsule. Therefore, it must be used in conjunction with external additional equipment, and the overall automation and linkage level are low.

In addition, for example, a capsule filling machine is disclosed in the patent document with patent application number: CN201520943790.7, whose main structures include a reel shaft, a grain smoothing device fixed shaft, a motor, a control panel, a driving device, a support frame, a reel, a tumbling shaft, a hopper, a grain smoothing device, a grain discharge port, a meter, a roller, a cutter, a bag discharger, a conveyor belt, a fixed pillar and a moving wheel. The reel shaft is fixedly arranged on the support frame, and a reel is arranged on the reel shaft. The grain smoothing device fixed shaft is fixed to the grain smoothing device, and the grain smoothing device fixed shaft is arranged on the support frame. The motor is fixed on the control panel, and the motor is connected to the tumbling shaft through a belt. The control panel is fixedly arranged on the support frame, and the middle of the driving device The equipment includes a meter, a roller, a cutter and a bagger. A moving wheel is fixed on the lower side of the support frame. The reel is arranged at the rear side of the hopper. The material sorter is located directly below the hopper and is fixed on the fixed axis of the grain sorter. The fixed device is arranged on the support frame and the grain outlet is located in the middle of the meter. The meter is fixed in the middle of the driving device. The roller is located between the meter and the cutter and the roller and the cutter are fixed on the driving device. The bagger is located on the lower side of the cutter and is fixed on the driving device. The conveyor belt is located on the lower side of the bagger and is fixed inside the support frame. The fixed pillar is connected to the support frame by bolts and the fixed pillar is arranged on the outside of the moving wheel.

The above patent only fills the filled capsules, and when filling, the western medicine capsules are placed in the hopper, and then the bracket frame is rotated upward and fixed with fixing bolts. After this step is completed, the motor and the drive device are started through the control panel, and the western medicine capsules in the hopper will be lowered into the feeder under the action of the rolling shaft, and the capsules will be sorted in the feeder, so that the capsules fall at a certain quantity and speed. This requires pre-coordination with the upstream capsule powder filling equipment. Similarly, when using capsule filling, it must be used in conjunction with multiple external equipment. There is a phenomenon of frequent transfer of capsules outside, the intermediate transition link is not easy to control, there is a greater risk of contamination, and the overall continuity of the entire equipment is relatively poor.

To this end, after analyzing the capsule filling process and filling equipment in the prior art, the present invention has designed a comprehensive filling system with a high degree of overall automation and capable of continuously completing capsule filling of granules and overall capsule filling into bottles, so as to better solve the problems existing in the prior art.

Detailed ways

The following is a detailed description of the embodiments of the technical solution of the present invention in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present invention. The specific structure of the present invention is shown in Figures 1-8.

Embodiment 1:

The capsule granule filling system comprises a rotary feeding and discharging assembly, on which a receiving station A, a waiting station B, a granule filling station C, and a return idle station D are evenly spaced along the circumference thereof; an empty capsule storage and discharging mechanism E is arranged above the receiving station A, and a linkage filling machine F is arranged above the granule filling station C; the empty capsule storage and discharging mechanism E is used for periodically feeding vertical empty capsules into the receiving station A on the rotary feeding and discharging assembly; and each ordered empty capsule passes through the receiving station A, the waiting station B, and the granule filling station C in sequence under the action of the rotary feeding and discharging assembly. The function of the receiving station A is to sequentially send the sorted empty capsules in the empty capsule storage and discharge mechanism E to the empty capsule vertical placement unit H at the receiving station A. When entering the empty capsule vertical placement unit H, each empty capsule on the capsule dropping disc 3 is aligned with the channel 301 and enters the corresponding capsule receiving lower cylinder 8 below, thereby completing the empty capsule discharge step at the receiving station A. During the above discharge step, the empty capsule discharge port of the entire empty capsule storage and discharge mechanism E is in a fixed state, and each empty capsule vertical placement unit H and the capsule dropping disc 3 thereon are synchronously rotated to sequentially receive each empty capsule vertically dropped from the empty capsule discharge port by using the empty capsule alignment channel 301. This discharge method discharges one empty capsule at a time, has high discharge accuracy, and the feeding position is accurately controllable. During the feeding process, the empty capsules have less contact with the outside, and the whole process is safer and more hygienic. The capsule dropping disc 3 and the empty capsule standing unit H at the receiving station A as synchronously moving integrated capsule storage components can realize revolution following the rotation of the main rotating disc 1, so that the four groups of the above-mentioned integrated capsule temporary storage components can realize sequential movement to the receiving station A through revolution to complete the receiving of empty capsules (at least 10 empty capsules can be received and stored each time when receiving empty capsules at the receiving station A, and the specific number is set according to the filling requirements and different molds are selected to manufacture the corresponding parts).

In any of the above schemes, it is preferred that the rotary feeding and discharging assembly includes a horizontally arranged main rotating disc 1, a main driving rotating mechanism 2 is installed at the central bottom of the main rotating disc 1, a capsule dropping disc 3 is installed in each installation circular cavity 101 at the material receiving station A, the waiting station B, the granule filling station C, and the return idle station D of the main rotating disc 1, a plurality of empty capsule alignment channels 301 are evenly spaced along the circumference of the surface of each capsule dropping disc 3, an empty capsule standing unit H is installed below each capsule dropping disc 3, a top supporting lifting and rotating mechanism is installed between the empty capsule standing unit H and the corresponding capsule dropping disc 3, the top of the top supporting lifting and rotating mechanism is fixedly connected to the bottom of the main rotating disc 1 at the corresponding position; the top supporting lifting and rotating mechanism at the granule filling station C is used to drive the empty capsule standing unit H below it and the empty capsules stored therein to move upward and cooperate with the capsule separating and combining mechanism 4 on the linkage filling machine F above it when in a high position.

When the rotary feeding and discharging assembly is working, it drives the main rotating disc 1 to rotate at a certain angle by the driving of the main driving rotating mechanism 2. The rotation of the main rotating disc 1 can drive the four capsule dropping discs 3 and the empty capsule standing unit H thereon to realize successive conversion among four different stations. After the empty capsules are placed inside the empty capsule standing unit H at the receiving station A, the lower negative pressure positioning unit is used to realize negative pressure adsorption positioning of the lower part of the capsule body G01 of each empty capsule. After adsorption and positioning, the empty capsule can remain stable inside the empty capsule standing unit H, and then enter the next waiting station B through revolution, and then continue to orbit to the granule filling station C. At the granule filling station C, the top support lifting and rotating mechanism is operated to drive the current empty capsule standing unit H and each empty capsule thereon in the adsorption and positioning state to move upward, and move to the highest position. At this time, the capsule cap G02 of each empty capsule extends to the top of the corresponding capsule dropping disc 3 to wait for the capsule body G02. 01, the capsule cap G02 is separated, and the linkage packaging machine F above the station is continued to be controlled to operate the capsule separation and combination mechanism 4 in place. The capsule separation and combination mechanism 4 moves downward to drive each gripping cap sleeve 403 to be respectively sleeved on the capsule cap G02 of the corresponding empty capsule. After the sleeve is completed, the upper negative pressure positioning unit is started to use negative pressure to adsorb the capsule cap G02 of each empty capsule on the gripping cap sleeve 403. At this time, since the capsule body G01 and the capsule cap G02 are both in a negative pressure adsorption fixed state, the overall upward movement of the capsule separation and combination mechanism 4 will separate the capsule cap G02 from the capsule body G01. At this time, the capsule separation and combination mechanism 4 is controlled to change the station 180°, and the particle quick loading mechanism 16 moves to the top of the particle filling station C. The discharge port of each particle precision quantitative discharger 1602 of the particle quick loading mechanism 16 is controlled to fill an appropriate amount of particles into the interior of each capsule body G01 directly below it. In this filling process, the filling accuracy is high and the filling flow rate is small, so the filling amount can be accurately controlled.

The lifting and rotating mechanism of the top support drives the capsule blanking disc 3, the empty capsule standing unit H, and the same-direction double-rod cylinder 6 to realize synchronous rotation through the rotation of the double-axis tight stepping motor. In addition, the synchronous double-rod cylinder can drive the lifting and lowering of the empty capsule standing unit H through the extension and retraction of its own piston rod, thereby realizing the high and low position control of the empty capsule, which is convenient for the later separation and combination of the capsule body G01 and the capsule cap G02 of the empty capsule.

The main drive servo motor 201 has an existing control program built in, which can set the angle of each rotation during rotation, and can also control the start and stop time by cooperating with the in-position switch. The control part belongs to the more conventional existing technology and will not be described in detail here.

The empty capsule storage and discharge mechanism E is used to periodically feed the empty capsules G in a vertical state to the receiving station A on the rotary feeding and discharging assembly;

The empty capsules G arranged in sequence pass through the material receiving station A, the waiting station B, and the particle filling station C in sequence under the action of the rotary feeding and discharging assembly.

The function of the material receiving station A is to sequentially deliver the sorted empty capsules inside the empty capsule storage and discharge mechanism E at the material receiving station A into the empty capsule standing unit H at the station. When entering the empty capsule standing unit H, each empty capsule on the capsule dropping disc 3 is aligned with the channel 301 and enters the corresponding capsule receiving lower cylinder 8 below, thereby completing the empty capsule discharge step at the material receiving station A.

When the above-mentioned discharge step is working, the empty capsule discharge outlet of the entire empty capsule storage and discharge mechanism E is in a fixed state, and each empty capsule upright placement unit H and the capsule dropping disc 3 thereon are synchronously rotated to sequentially receive each empty capsule vertically dropped from the empty capsule discharge outlet by the empty capsule alignment channel 301.

S3: Empty capsules are loaded into the vertical placement unit H from the current receiving station A:

Start the rotary feeding and discharging assembly and the empty capsule storage and discharging mechanism E of the capsule granule filling system, control the capsule dropping disc 3 at the receiving station A of the rotary feeding and discharging assembly to rotate, and sequentially move the empty capsule alignment channel 301 on the capsule dropping disc 3 to just below the capsule vertical row pipe 13 of the empty capsule storage and discharging mechanism E, at which time the bottom empty capsule will fall into the corresponding capsule receiving lower cylinder 8 of the empty capsule vertical placement unit H, and at the same time, the top of the empty capsule inside the capsule receiving lower cylinder 8 will be flush with the top of the empty capsule alignment channel 301, which will block the capsule inside the upper capsule vertical row pipe 13 from continuing to fall into the capsule receiving lower cylinder 8, and the empty capsule discharge of the current empty capsule vertical placement unit H is completed;
