Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production and filling equipment technology, specifically a filling device for bottled pharmaceutical production. Background Technology

[0002] In existing bottled medicine production and filling equipment, the filling process mainly relies on conveyor belts. During this process, the bottles are placed on the conveyor belt and transported to the bottom of the filling machine. Below the filling machine, multiple filling heads are installed; these heads descend when the bottles reach a designated position and insert into the bottle to perform filling. However, this traditional filling method has certain drawbacks.

[0003] First, due to conveyor belt issues, medicine bottles are prone to slight misalignment during transport. This misalignment can be caused by factors such as unstable conveyor belt speed, conveyor belt wear, or irregular bottle shape. When one bottle misaligns, it can cause all subsequent bottles to misalign, thus affecting the stability of the entire filling process. In this situation, the filling head may not be able to accurately insert into the bottle during descent, making filling impossible.

[0004] Secondly, when the bottle shifts, the filling head may insert into the bottle body, causing damage to both. This not only affects the appearance of the bottle but may also lead to leakage, impacting drug quality. Furthermore, damaged filling heads need replacement, increasing production costs and downtime. While existing technologies have made some improvements to address these issues, certain limitations remain. Therefore, it is necessary to research a novel filling device for bottled medicine production to improve the stability and efficiency of the filling process. Utility Model Content

[0048] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Various changes can be made to the implementation scheme as long as the effects of the present invention can be achieved.

[0049] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0050] Reference Figure 1-4 The filling device for bottled medicine production in this implementation plan is described.

[0051] The filling device includes a machine base 1, a conveyor belt 3, and multiple filling heads 22. The conveyor belt 3 is mounted on the machine base 1 and transports the medicine bottles from one end to the other. Conveyor belts are installed at both ends of the conveyor belt 3 to feed empty bottles before filling into the conveyor belt 3 and to output the filled bottles.

[0052] In one embodiment, there are two conveyor belts 3, arranged side-by-side on the machine base 1; a first push rod 5 is provided on the side support 2, preferably an electrically telescopic rod. The output end of the first push rod 5 is fixed to the lower crossbeam 18 and the upper crossbeam 19, driving the lower crossbeam 18 and the upper crossbeam 19, as well as the filling head 22 and the clamping mechanism, to reciprocate between the two conveyor belts 3. After the empty bottles on the first conveyor belt 3 are filled, the bottles on the first conveyor belt 3 are output, and empty bottles are input. At this time, the first push rod 5 pushes the lower crossbeam 18 and the upper crossbeam 19, as well as the filling head 22 and the clamping mechanism, to move towards the other conveyor belt 3 to fill the empty bottles on the other conveyor belt 3. The two conveyor belts 3 are used alternately to fill empty bottles, improving filling efficiency.

[0053] Furthermore, guide frames 4 are provided on the sides of the conveyor belt 3 along the conveying direction. There are multiple guide frames 4. For example, when there is one conveyor belt 3, there are two guide frames 4, positioned on both sides of the conveyor belt 3 to shield the bottles and prevent them from tipping over during transport. When there are two conveyor belts 3, there are three or four guide frames 4. Three guide frames 4 are arranged in parallel, with the gap between adjacent guide frames 4 suspended above the conveyor belt 3; four guide frames 4 are divided into two groups, with each group positioned on one side of the conveyor belt 3.

[0054] Furthermore, the filling device also includes a side support 2, which is fixed on both sides of the machine base 1. The top of the side support 2 is provided with a lower crossbeam 18 and an upper crossbeam 19. The bottom of the lower crossbeam 18 is slidably connected to the side support 2 via a fourth guide rail 20. The fourth guide rail 20 is used to assist the movement of the lower crossbeam 18 and the upper crossbeam 19 on the side support 2.

[0055] In this embodiment, clamping mechanisms are provided on the lower crossbeam 18 and the upper crossbeam 19 to clamp the bottle, ensuring that the empty bottle is directly below the filling head 22 and preventing tilting during filling. Specifically, the clamping mechanism includes multiple fixed bodies 14, a pushing assembly, a clamping frame, and a lifting assembly. Each filling head 22 is correspondingly mounted on each fixed body 14. The filling head 22 is a conventional filling mechanism, whose tube can extend downwards and be inserted into the bottle for filling, which will not be described in detail here.

[0056] In this embodiment, the pushing assembly moves laterally on the lower crossbeam 18. The pushing assembly includes two second push rods 6, a first connecting frame 8 and a second connecting frame 17, and a first guide rail 7. The second push rods 6 are preferably electrically telescopic rods. Specifically, the two second push rods 6 are arranged opposite each other at both ends of the lower crossbeam 18 and are located on the front sides of the lower crossbeam 18. The first connecting frame 8 and the second connecting frame 17 are arranged at the front ends of the two second push rods 6 and are respectively arranged on the front and rear sides of the filling head 22. The first connecting frame 8 and the second connecting frame 17 are arranged along the arrangement direction of the filling head 22. The first guide rail 7 is arranged between the first connecting frame 8 and the second connecting frame 17 and the output end of the second push rod 6, allowing the first connecting frame 8 and the second connecting frame 17 to slide up and down at the output end of the second push rod 6.

[0057] In this embodiment, the clamping frame is fixed to the pushing assembly, and a clamping ring 24 is provided at the bottom of the clamping frame. The clamping ring 24 is semi-circular, and two opposite clamping rings 24 interlock to form a ring. Under the action of the pushing assembly, the clamping frame is pushed to move relative to each other, so that the clamping ring 24 clamps the bottle mouth.

[0058] Specifically, the clamping frame includes multiple first clamping plates 9 and multiple second clamping plates 10, and clamping rings 24 are disposed on two opposite first clamping plates 9 and second clamping plates 10.

[0059] Multiple first clamping plates 9 are disposed on one side of each fixing body 14 and fixed on the first connecting frame 8; multiple second clamping plates 10 are disposed on the other side of each fixing body 14 and fixed on the second connecting frame 17; wherein, the first clamping plates 9 and the second clamping plates 10 on both sides of each fixing body 14 are arranged opposite to each other.

[0060] The clamping frame also includes multiple sliders 15 and a third guide rail 16. Each first clamping plate 9 and second clamping plate 10 slides up and down on the surface of each slider 15 in a one-to-one correspondence; the third guide rail 16 is fixed on the lower crossbeam 18, and each slider 15 slides laterally on the third guide rail 16.

[0061] During clamping, the two second push rods 6 push the first connecting frame 8 and the second connecting frame 17 to move inward, causing the first clamping plate 9 and the second clamping plate 10 on both sides of each fixed body 14 to move closer to each other and clamp the bottle mouth. When the bottle body shifts, the clamped bottle body is located directly below the filling head 22, ensuring that each bottle body and each filling head 22 can be relative to each other, thus improving filling accuracy.

[0062] The bottom of the first clamping plate 9 and the second clamping plate 10 are provided with limiting members 23, which are located above the clamping ring 24. The limiting members 23 are semi-circular, and the two limiting members 23 interlock to form a ring. After the filling head 22 descends, the tube end of the filling head 22 is inserted into the bottle body, and the tube body is engaged with the ring formed by the combination of the limiting members 23 to prevent it from touching the bottle mouth and causing a chip in the bottle mouth, or to prevent the tube body of the filling head 22 from being contaminated with medicine.

[0063] In this embodiment, the lifting component is mounted on one of the fixed bodies 14, preferably on the fixed body 14 located in the middle, to drive the clamping frame to move up and down, so that the clamping frame can move up and down stably.

[0064] Specifically, the lifting assembly includes a base 21, a frame 11, and a second guide rail 13. The base 21 is fixed to one of the fixed bodies 14; a third push rod 12 is fixed to the base 21, preferably an electric telescopic rod, with its output end penetrating the base 21; the frame 11 is fixed to the output end of the third push rod 12; the second guide rail 13 is located at the bottom of the frame 11, and the first clamping plates 9 and 10 on both sides of the fixed body 14 in the middle are slidably connected to the second guide rail 13 to ensure that the first clamping plates 9 and 10 can move normally relative to each other. The third push rod 12 pushes the frame 11 and the first clamping plates 9 and 10 connected to the frame 11 to descend. Since each first clamping plate 9 and 10 is connected to the first connecting frame 8 and the second connecting frame 17, all the first clamping plates 9 and 10 descend synchronously, causing the bottom clamping ring 24 to descend to both sides of the bottle mouth.

[0065] Working principle:

[0066] Step 1: The third push rod 12 advances the working drive plate frame 11 to descend, causing all the first clamping plates 9 and the second clamping plates 10 to descend synchronously, so that the clamping ring 24 is located on both sides of the bottle mouth of the bottle body.

[0067] Step 2: The two second push rods 6 push the first connecting frame 8 and the second connecting frame 17 to move inward, causing the first clamping plate 9 and the second clamping plate 10 on both sides of each fixed body 14 to move closer to each other and clamp the bottle mouth. After clamping, the bottle is located directly below the filling head 22, ensuring that each bottle and each filling head 22 are relative to each other.

[0068] Step 3: The retraction of the third push rod 12 causes the plate frame 11 to rise, which in turn causes all the first clamping plates 9 and second clamping plates 10 to rise synchronously while holding the bottle. The filling head 22 then descends and inserts into the bottle for filling. When the first clamping plates 9 and second clamping plates 10 rise, they cause the first connecting frame 8 and the second connecting frame 17 to slide along the first guide rail 7 at the output end of the second push rod 6, ensuring the normal lifting and lowering of the first connecting frame 8 and the second connecting frame 17.

[0069] Step 4: After filling is completed, the third push rod 12 pushes the working drive plate frame 11 down, causing all the first clamping plates 9 and the second clamping plates 10 to fall down synchronously, so that the bottle falls back onto the conveyor belt 3; and the second push rod 6 retracts, causing the first connecting frame 8 and the second connecting frame 17 to move outward relative to each other, so that the clamping ring 24 disengages from the bottle.

[0070] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
