DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] The utility model aims to provide a drop pill filling machine to solve the problems existing in the prior art. By arranging a clamping module, the medicine bottles on the conveyor belt can be clamped horizontally to ensure the stability of the medicine bottles during the dosing process, thereby avoiding the problem of medicine bottles vibrating or shifting due to equipment vibration or other factors, resulting in dosing failure.

[0034] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] like Figures 1 to 8As shown, this embodiment discloses a drop pill filling machine, including a bottle separation module 1, a weighing and unloading module 2, a linear transport module 3 and a clamping module 4. The bottle separation module 1 is connected to the linear transport module 3, and the linear transport module 3 includes a conveyor belt 5. The weighing and unloading module 2 is located above the conveyor belt 5. The clamping module 4 includes a lifting bracket 6 and a fixed bracket 7, and the fixed bracket 7 is respectively located on both sides of the horizontal conveyor belt 5; the fixed bracket 7 is provided with a tension spring 8 and a guide shaft 9 that can slide horizontally along a direction perpendicular to the conveying direction of the conveyor belt 5, and the end of the guide shaft 9 is fixed with a clamping claw 10 for clamping the medicine bottle 16, and the end of the clamping claw 10 is an arc surface adapted to the outer wall surface of the medicine bottle 16, and the height of the clamping claw 10 on both sides of the conveyor belt 5 is equal. The tension spring 8 is sleeved on the guide shaft 9, one end of which is connected to the fixed bracket 7, and the other end is connected to the guide shaft 9 or the clamping claw 10. The lifting bracket 6 is connected to the lifting drive mechanism, and the lifting bracket 6 is provided with a wedge block 34 located between the clamping claw 10 and the fixed bracket 7. The side of the wedge block 34 away from the clamping jaw 10 is a vertical surface, and the side close to the clamping jaw 10 is an inclined surface, which can be a plane or an arc surface. From top to bottom, the cross-sectional area of ​​the wedge block 34 gradually increases, and the distances between points at different heights on the inclined surface and the conveyor belt 5 gradually decrease from top to bottom.

[0036] Under normal conditions, the clamp 10 is in its original position under the elastic force of the tension spring 8. After the linear transport module 3 delivers the medicine bottle 16 to the designated loading position, the lifting drive mechanism drives the lifting bracket 6 to rise. As the wedge block 34 rises with the lifting bracket 6, the inclined surface of the wedge block 34 abuts against the end of the clamp 10, and gradually squeezes the clamp 10 inward, so that the clamp 10 moves toward the medicine bottle 16 and gradually clamps the medicine bottle 16. After the clamp 10 clamps the medicine bottle 16, the weighing and unloading module 2 loads medicine into the medicine bottle 16. After the loading is completed, the lifting drive mechanism drives the lifting bracket 6 to descend, and the wedge block 34 gradually loses its limiting effect on the clamp 10; the clamp 10 gradually returns to its original position under the elastic force of the tension spring 8, and the medicine bottle 16 is released. The medicine bottle 16 containing the pills is transported to the next station by the linear transport module 3.

[0037] This embodiment can horizontally clamp the medicine bottle 16 on the conveyor belt 5 by setting the clamping module 4, ensuring the stability of the medicine bottle 16 during the dosing process, and avoiding the problem of medicine bottle 16 vibrating or shifting under the influence of equipment vibration or other factors, resulting in dosing failure. At the same time, the clamping module 4 in this embodiment has a simple structure, is easy to implement, has a low investment cost, and is easy to promote and use.

[0038] Furthermore, in this embodiment, there are two guide shafts 9 connected to a clamp 10 to avoid the problem that the guide shaft 9 rotates and the clamp 10 cannot clamp the medicine bottle 16; in order to further ensure the stability of the translation of the guide shaft 9, in this embodiment, the guide shaft 9 is installed on the fixed bracket 7 through a linear bearing 11.

[0039] Furthermore, in this embodiment, a buffer block 12 is provided on the clamping jaw 10, and the buffer block 12 is connected to the end of the tension spring 8 and the end of the guide shaft 9. The buffer block 12 is made of elastic material, and when the clamping jaw 10 contacts the medicine bottle 16, the wedge block 34 continues to rise to compress the buffer block 12, thereby preventing the clamping force on the medicine bottle 16 from being too large, resulting in damage or deformation of the medicine bottle 16.

[0040] Furthermore, in the present embodiment, the lifting drive mechanism is a clamping cylinder 13 , which is located below the lifting bracket 6 , and a piston rod of the clamping cylinder 13 is connected to the bottom of the lifting bracket 6 .

[0041] In this embodiment, the linear transport module 3 includes a conveying base 14 for installing the conveyor belt 5. First guide plates 15 are arranged in parallel on both sides of the conveyor belt 5. The interval between the two first guide plates 15 is adapted to the diameter of the medicine bottle 16 to prevent the medicine bottle 16 from falling from the conveyor belt 5.

[0042] The conveying base 14 is also provided with a position sensor 17 for monitoring the position of the medicine bottle 16. When the position sensor 17 detects that the medicine bottle 16 has reached the specified position, it sends a signal to the control module, and the control module controls the clamping cylinder 13 to move upward. The process of driving the movement of the clamping cylinder 13 by monitoring the position of the medicine bottle 16 by the position sensor 17 is well known to those skilled in the art.

[0043] Furthermore, in this embodiment, the weighing and unloading module 2 includes a weighing base 18, a silo 19 arranged on the weighing base 18, a vibrating trough 20, a weighing sensor 21, and a weighing bucket 22 installed on the weighing sensor 21, one end of the vibrating trough 20 is located below the silo 19, there is a certain gap between the bottom of the vibrating trough 20 and the discharge port at the bottom of the silo 19, the other end of the vibrating trough 20 is located above the weighing bucket 22, and the vibrating trough 20 is connected to the vibrator 35. The pills inside the silo 19 fall on the vibrating trough 20, and the vibrating trough 20 transports the pills to the weighing bucket 22 under the vibration of the vibrator 35; as the pills are continuously transported, the pills in the silo 19 gradually fall into the vibrating trough 20. The weighing sensor 21 weighs the pills in the weighing bucket 22. When the filling requirement of each medicine bottle 16 is reached, the vibrator 35 stops vibrating, the pills on the vibration trough 20 do not move, and the pills at the drop opening will not continue to drop downward under the pressure of the pills stored externally. Those skilled in the art should know that in order to reduce the influence of the vibration generated by the vibrator 35 on the weighing sensor 21, a buffer member should be provided between the weighing sensor 21 and the weighing base 18, and a wider measurement frequency of the weighing sensor 21 should be selected.

[0044] In this embodiment, the weighing hopper 22 includes a hopper body 23 and a baffle 24 hinged to the hopper body 23. The hopper body 23 has a feeding bevel below, and the baffle 24 is buckled on the feeding bevel. The baffle 24 is connected to a baffle 25. A weighing cylinder 27 is also provided on the weighing base 18. A paddle 26 is fixed to the end of the telescopic rod of the weighing cylinder 27. The paddle 26 is located below the baffle 25. A lower hopper 28 is provided below the weighing hopper 22. A lifting cylinder 29 is also vertically provided on the weighing base 18. The end of the telescopic rod of the lifting cylinder 29 is fixedly connected to the lower hopper 28 through a connecting plate. The lower hopper 28 has a conical body and a straight pipe section connected to the bottom of the conical body. The straight pipe section is directly opposite to the bottle mouth of the medicine bottle 16. When the quality of the pills in the weighing hopper 22 reaches the standard, the lifting cylinder 29 drives the lower hopper 28 to descend until the straight pipe section is inserted into the inside of the medicine bottle 16. Then the telescopic rod of the weighing cylinder 27 drives the paddle 26 to move upward, and the paddle 26 drives the baffle 25, and drives the baffle 24 to rotate, so that the feeding bevel is opened, and the pills fall into the lower hopper 28 from the feeding bevel, and finally the pills are sent to the medicine bottle 16. After the pills are bottled, the lifting cylinder 29 drives the lower hopper 28 to rise, and the straight pipe section is separated from the bottle mouth of the medicine bottle 16, and the conveyor belt 5 drives the medicine bottle 16 to enter the next process.

[0045] In this embodiment, the bottle separation module 1 can adopt an existing bottle separation machine, including a bottle separation base 30, a dispersion plate 31 arranged on the bottle separation base 30, and a second guide plate 32 fixed on the bottle separation base 30; a dispersion plate 33 is also fixed on the bottle separation base 30, and the dispersion plate 33 is arranged in the middle of the dispersion plate 31. After the medicine bottle 16 is placed on the dispersion plate 31, the dispersion plate 31 drives the medicine bottle 16 to rotate. Under the action of the dispersion plate 33, the medicine bottle 16 will be neatly arranged into the guide channel formed by the second guide plate 32, and finally move to the conveyor belt 5. The specific structure and working principle of the dispersion plate 33, the dispersion plate 31 and the second guide plate 32 are well known to those skilled in the art, and will not be described in detail in this embodiment.

[0046] Therefore, the drop pill filling machine in this embodiment can realize the filling operation of accurately filling the drop pills into the medicine bottle 16, with a high degree of automation, which can improve the filling efficiency and enterprise production capacity and reduce the labor intensity of the staff; at the same time, the drop pill filling machine in this embodiment is suitable for the filling of various drop pill medicines such as Huanglong Drop Pills and Danshen Drop Pills, and has a wide range of applications.

[0047] Adaptive changes made according to actual needs are all within the protection scope of this utility model.

[0048] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
