Description

TECHNICAL FIELD

[0001] The present application relates to the field of capsule filling equipment, in particular to a full-automatic capsule filling machine. BACKGROUND

[0002] Capsule filling machines are important equipment in the pharmaceutical industry for filling powders or other substances into capsules. With the continuous development of the pharmaceutical industry, the degree of automation is continuously improved, and the application of full-automatic capsule filling machines is becoming more and more widespread. Such equipment not only improves production efficiency, reduces the error of manual operation, but also improves the quality and consistency of drugs. Especially in large-scale production, the advantages of full-automatic capsule filling machines are more obvious, which can significantly reduce production costs, ensure the consistency and stability of product quality, and meet the market demand for efficient production and high-quality drugs. However, the existing full-automatic capsule filling machines still have some shortcomings in actual application, which need to be further improved and perfected.

[0003] At present, in order to realize the automatic filling of capsules, the commonly used solutions include but are not limited to the following: one is to grasp the capsule body and the capsule cap by a mechanical hand, and place them in designated positions respectively; two is to arrange the capsule body and the capsule cap in order by using a vibrating disc, and then send them into the filling station through a conveying belt; three is to adopt a rotary disc type design, and complete the filling and capping process of the capsules in turn through multiple stations on the rotary disc. Although these methods can improve production efficiency to a certain extent, there are still some problems.

[0004] For the related technologies in the above, the inventor believes that the mechanical hand grasping method is easy to cause damage to the capsules, and the vibrating disc arrangement method is easy to cause capsule jamming or mispositioning when handling a large number of capsules; and although the rotary disc type design is relatively stable, it is easy to cause the capsule body and the capsule cap to be unable to be accurately separated during the separation and capping process, and sometimes even needs to add a detection and rejection process of waste capsules, which will greatly affect the filling quality and production efficiency.

It also includes a rotating motor 2, which is mounted on the frame 1. The transmission end of the rotating motor 2 is vertically arranged, and a rotating plate 201 is provided on the transmission end of the rotating motor 2. Several bearing devices 3 are evenly arranged on the rotating plate 201. The bearing devices 3 are provided with a locking mechanism 301 and an anti-drop mechanism 302. A separation device 4 is also provided on the support frame. The separation device 4 includes a separation cylinder 401 mounted on the frame 1. The transmission end of the separation cylinder 401 is connected to a separation block 402. The separation block 402 is slidably connected to the frame 1. An adsorption suction cup 403 is provided on the separation block 402. The adsorption suction cup 403 is connected to a separation pump 404. The adsorption suction cup 403 can adsorb onto the capsule body, thereby improving the capsule filling accuracy and production efficiency.

[0038] Specifically, as an embodiment, the rotating motor 2 comprises a motor body and a transmission shaft. The motor body can be a servo motor or a stepper motor, both of which have high control accuracy and response speed, and are suitable for precise control occasions. The transmission shaft is coaxially arranged with the motor body, and a key groove is arranged on the transmission shaft to cooperate with the key on the rotating plate 201 to realize power transmission. The rotating plate 201 is provided with a plurality of positioning holes which are uniformly distributed and used to fix the bearing device 3. When the rotating motor 2 works, the motor body drives the transmission shaft to rotate, and then drives the rotating plate 201 and the bearing device 3 above it to rotate synchronously.

A clamping mechanism 301 is arranged on the capsule cap bearing mechanism 303, and at least one set of anti-falling mechanism 302 is arranged on the capsule body bearing mechanism 304. When the rotating plate 201 rotates, the bearing device 3 rotates with the rotating plate 201 and sequentially passes through each station to complete the filling, merging and separation of the capsules and the like.

[0040] The capsule cap bearing mechanism 303 comprises a capsule cap bearing block 3031, and a plurality of capsule cap bearing holes 3032 are arranged on the capsule cap bearing block 3031.

[0041] Reference Figure 3 The clamping mechanism 301 comprises a clamping ring 3011 arranged in the capsule cap bearing hole 3032. The inner diameter of the clamping ring 3011 is slightly smaller than the diameter of the capsule cap, so that the lower edge of the capsule cap is pressed on the clamping ring 3011 when the capsule cap enters the bearing hole, thereby ensuring that the capsule cap is in the hole and cannot be pulled out from below

[0042] The capsule body bearing mechanism 304 comprises a capsule body bearing block 3041, and a plurality of capsule body bearing holes 3042 are arranged on the capsule body bearing block 3041. The anti-falling mechanism 302 is arranged in the capsule body bearing hole 3042. The capsule body bearing hole 3042 is cylindrical, facilitating the capsule body to smoothly enter and be fixed in the hole. When the capsule body enters the capsule body bearing hole 3042, the anti-falling mechanism 302 starts to work due to the shape of the capsule body, ensuring that the capsule body is firmly fixed in the hole.

When the capsule body enters the capsule body bearing hole 3042, first, the capsule body will press on the first guide surface 3023, then push the first guide block 3022 to move horizontally, the first guide block 3022 will press on the second guide surface to push the second guide block 3025 to move vertically, the movement is transmitted to the third guide surface 3029 to push the third guide block 3028 to move, so that the third guide block 3028 extends below the capsule to cooperate with the separating device 4 to prevent the capsule body from falling and position the descending distance of the capsule body, so that each capsule can descend to the same position, and at the same time, the first guide block 3022 will press on the capsule body from multiple directions due to the first reset spring 3024, so as to achieve the clamping and positioning effect of the capsule body.

[0044] When the capsule body is taken out, the first reset spring 3024, the second reset spring 3027 and the third reset spring 30210 will return to the original state, so that the first guide block 3022, the second guide block 3025 and the third guide block 3028 return to the initial position again, waiting for the next work.

[0045] Reference Figure 3 The stretching mechanism 305 comprises a stretching cylinder 3051 arranged on the capsule cap bearing mechanism 303, the stretching cylinder 3051 being arranged obliquely, and the transmission end of the stretching cylinder 3051 being connected to the capsule body bearing mechanism 304. The stretching cylinder 3051 functions to separate the capsule body bearing block 3041 and the capsule cap bearing block 3031 when the capsule cap and the capsule body approach, so that the subsequent work station filling device and the like can be better matched to complete the work, the stroke of the stretching cylinder 3051 can be adjusted according to actual needs, and after the capsule body and the capsule cap are separated, the stretching cylinder 3051 extends to push the capsule cap bearing mechanism 303 to move downward and sideways.

The separation cylinder 401 functions to pull the capsule body away from the capsule cap through the action of the cylinder when the capsule body is separated from the capsule cap. The suction chuck 403 is made of a reversibly deformed high-elastic polymer material, has good flexibility and resilience, can closely adhere to the surface of the capsule body, and ensures the adsorption effect. When the capsule body needs to be separated from the capsule cap, the separation cylinder 401 is extended, the separation block 402 is pushed to move towards the capsule body, the suction chuck 403 is adhered to the bottom of the capsule body, the separation pump 404 is started, negative pressure is generated, and the capsule body is pulled away from the capsule cap through the cooperation of the suction chuck 403 and the cylinder movement.
