[0002] In the pharmaceutical packaging machinery industry, the capping process after bottle filling is a crucial step in ensuring product sealing and safety. Current technologies generally employ automated equipment to handle cap gripping and pressing, typically using mechanical grippers or vacuum suction cups for cap picking and transfer. However, with the increasing demand for flexible production lines in the pharmaceutical industry, clamping devices capable of accommodating caps of different sizes are gradually becoming the direction of technological development.

[0003] In existing clamping devices, a rigid clamping arm combined with a drive motor is often used to achieve the opening and closing action. These devices typically achieve linear movement of the clamping arm through a lead screw or linear guide, and use a position sensor to detect the clamping status. Due to the dimensional tolerances and shape differences of bottle caps, local stress concentrations may occur between the rigid clamping surface and the outer surface of the bottle cap, indicating room for improvement in clamping stability and packaging quality.

[0004] Therefore, it is necessary to design a clamping device that can adapt to bottle caps of different sizes and, to a certain extent, avoid rigid contact between the clamping surface and the outer surface of the bottle cap. Utility Model Content

[0044] The embodiments of this utility model will be described in detail below.

[0045] This utility model discloses a flexible adaptive medicine bottle filling and capping clamping device.

[0046] Figure 1 A schematic diagram of a flexible adaptive medicine bottle filling and capping clamping device and a bottle cap supply device. Figure 2 This is a schematic diagram of the third support, clamp, and airbag assembly.

[0047] In this embodiment, the support system 1 adopts a three-level support structure consisting of a first support 11, a second support 13 and a third support 15.

[0048] The first support 11 is fixed to the working ground by anchor bolts, and its function is to provide stable foundation support.

[0049] The second support 13 is connected to the first support 11 via the first cylinder 12. The output shaft of the first cylinder 12 moves along a first direction, its function being to adjust the position of the second support 13 relative to the first support 11. The first cylinder 12 is a standard type cylinder, fixed to the first support 11 by bolts. In this embodiment, the first direction is a vertical direction; in other embodiments, the first direction may also be an inclined direction.

[0050] The third support 15 is connected to the second support 13 via the second cylinder 14. The output shaft of the second cylinder 14 moves along the second direction, which adjusts the position of the third support 15 relative to the second support 13. The second cylinder 14 is a standard cylinder and is fixed to the second support 13 with bolts. The first direction and the second direction are not parallel. In this embodiment, the first direction and the second direction are perpendicular to each other, that is, the second direction is horizontal. In other embodiments, the first direction and the second direction can also be at acute angles such as 30 degrees, 45 degrees or 60 degrees, or obtuse angles such as 120 degrees or 135 degrees. This arrangement allows the clamp 2 to be adjusted in position in multi-dimensional space.

[0051] The clamp 2 is mounted on the third bracket 15. The clamp 2 includes a fixed clamping arm 21, a drive motor 22, and a movable clamping arm 23.

[0052] The fixed clamping arm 21 is fixedly connected to the lower end face of the third bracket 15 by bolts, and its function is to provide a fixed clamping reference surface.

[0053] The drive motor 22 is a servo motor, fixed to the third bracket 15 via a motor mount. The output shaft of the drive motor 22 and the movable clamping arm 23 form a lead screw pair, which precisely controls the linear movement distance of the movable clamping arm 23. The lead of this lead screw pair is 5mm. In this embodiment, the lead screw pair adopts a ball screw structure; in other embodiments, the lead screw pair can also be a trapezoidal lead screw structure.

[0054] The movable clamping arm 23 is connected to the third bracket 15 through a sliding pair. Its function is to move closer to or further away from the fixed clamping arm 21 along a straight line under the drive of the drive motor 22.

[0055] A guide rail 151 is fixedly mounted on the third support 15. The guide rail 151 is a linear guide rail fixed to the third support 15 by bolts, and its function is to provide precise guidance for the movable clamping arm 23. Correspondingly, the movable clamping arm 23 has a guide groove 231 that mates with the guide rail 151. The guide groove 231 is precision machined to form a clearance fit with the guide rail 151, and the clearance is controlled within the range of 0.02-0.05mm. In this embodiment, there is one guide rail 151; in other embodiments, there may be two or three guide rails 151, the specific number of which is determined according to the length of the movable clamping arm 23 and the load requirements. The sliding pair formed by the guide rail 151 and the guide groove 231 can restrict the movable clamping arm 23 to move only along a predetermined linear direction. This structure can reduce vibration and offset during movement.

[0056] The airbag assembly 3 includes a fixed airbag 31 and a moving airbag 32.

[0057] The fixed air bladder 31 is fixed to the end of the fixed clamping arm 21 by adhesive bonding, facing the movable clamping arm 23. The function of the fixed air bladder 31 is to form flexible contact with one side surface of the bottle cap. The wall thickness of the fixed air bladder 31 is 1.5-2.0 mm.

[0058] The movable airbag 32 is fixed to the end of the movable clamping arm 23 by adhesive bonding, facing the fixed clamping arm 21. Its function is to form flexible contact with the other surface of the bottle cap. The dimensions of the movable airbag 32 are the same as those of the fixed airbag 31. The fixed airbag 31 and the movable airbag 32 are connected to an external air source through polyurethane tubing. The external air source consists of an electric air compressor and a precision pressure regulating valve.

[0059] In this embodiment, the initial shape of the fixed airbag 31 and the moving airbag 32 is hemispherical; in other embodiments, the initial shape of the fixed airbag 31 and the moving airbag 32 may also be cylindrical, rectangular or trapezoidal to accommodate bottle caps of different shapes.

[0060] The controller (not shown in the figure) is a programmable logic controller (PLC) electrically connected to the drive motor 22 via a cable. Its function is to control the start, stop, and direction of the drive motor 22. In this embodiment, the controller is further electrically connected to the electrically controlled valve (not shown in the figure) of the external air source via a signal line. Its function is to adjust the inflation pressure of the fixed air bag 31 and the moving air bag 32 according to the outer dimensions of the bottle cap. The electrically controlled valve is a proportional valve. The controller can be installed in the equipment body or in a separate control cabinet, depending on the site requirements. In other embodiments, the controller can also be implemented using an industrial computer or an embedded system.

[0061] Furthermore, based on the flexible adaptive medicine bottle filling and capping clamping device disclosed in the above embodiments, a bottle cap supply device is also disclosed.

[0062] Figure 3 A schematic diagram (perspective view) of a bottle cap supply device.

[0063] The bottle cap supply assembly 4 is located directly below the clamp 2, and includes a bottle cap compartment 41, a lifting motor 42, and a bracket 43.

[0064] The bottle cap compartment 41 is fixed to the working ground by a bracket. Its interior has a receiving cavity 411, which is formed by connecting a circular storage cavity 412 and a rectangular limiting cavity 413. The storage cavity 412 is used to accommodate multiple bottle caps, and its diameter is designed according to the bottle cap specifications. In this embodiment, the diameter is 50mm; in other embodiments, the diameter of the storage cavity 412 can also be 40mm, 60mm, or 80mm.

[0065] The lifting motor 42 is a stepper motor, which is fixedly installed on the side of the bottle cap compartment 41 through the motor mount, and its output shaft and bracket 43 form a screw and nut pair.

[0066] The bracket 43 includes a lifting portion 431 and a limiting handle 432. The shape of the lifting portion 431 matches the circular cross-section of the storage cavity 412, and its function is to lift the bottle cap upward. The shape of the limiting handle 432 matches the rectangular cross-section of the limiting cavity 413, and its function is to prevent the bracket 43 from rotating during lifting and lowering. In this embodiment, the cross-section of the lifting portion 431 is circular; in other embodiments, the cross-section of the lifting portion 431 may also be square, cross-shaped, or star-shaped.

[0067] Overall, this utility model adopts a combination of a multi-degree-of-freedom adjustment structure of the support system 1, a precision screw drive structure of the clamp 2, and a flexible contact structure of the airbag assembly 3. By moving the output shafts of the first cylinder 12 and the second cylinder 14 in different directions, the clamp 2 can adapt to medicine bottles in different positions.

[0068] The precise displacement control of the moving clamping arm 23 is achieved through the cooperation of the drive motor 22 and the lead screw pair; the clamping surface can be adapted to bottle caps of different shapes and sizes by adjusting the inflation pressure of the fixed air bladder 31 and the moving air bladder 32. This structural configuration can reduce the risk of damage to the bottle cap surface to a certain extent and improve clamping stability.

[0069] The intelligent control method of the controller can coordinate the working parameters of the drive motor 22 and the airbag assembly 3 to realize the automatic identification and processing of bottle caps of different specifications, which has a certain positive effect on improving the adaptability and ease of operation of the equipment.

[0070] The automatic lifting function of the bottle cap supply component 4 and the coordinated operation of the clamp 2, through the lifting motor 42 driving the bracket 43 to move in the vertical direction, lift the bottle cap from the storage cavity 412 to the clamping station, forming a complete bottle cap supply and clamping system, which has practical value in improving the automation level of the production line.

[0071] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
