Description

Technical Field

[0001] The utility model relates to the detection field of the pharmaceutical industry, in particular to a bottle turning device. Background Art

[0002] In the pharmaceutical industry, the foreign body automatic inspection machine (commonly known as the light inspection machine) is an indispensable quality inspection equipment used to detect whether there are foreign bodies in medicines. When performing foreign body inspection on medicines, the medicine to be inspected needs to be rotated at high speed, and then the packaging container of the medicine is operated, and the liquid medicine continues to rotate under the action of inertia, and then a sequence of images is taken at high speed, and then the trajectory changes of the foreign bodies in the sequence images are compared to determine whether there are foreign bodies in the liquid medicine.

[0003] Due to its special shape, the prefilled syringe has a curled edge at the tail and a Luer mouth for installing the needle at the head. In order to prevent foreign objects from entering the Luer mouth and not coming out during the inspection, the automatic inspection machine for foreign objects in prefilled syringes generally clamps the bottle with the Luer mouth facing up and the curled edge facing down. The upstream equipment of the light inspection machine is generally a nesting machine or an automatic bottle unloader, which is then transported to the light inspection machine through a conveyor line; the products that come in are all in the posture of the curled edge on top and the Luer mouth on the bottom. Therefore, when entering the large plate to detect foreign objects, the medicine bottle needs to be turned 180°.

[0004] Traditional automatic foreign body inspection machines for prefilled syringes generally have two ways to flip 180°. One is to use a screw + torsion track, which guides the torsion track to achieve a 180° flip of the prefilled syringe. However, the torsion track will be in contact with the prefilled syringe, causing the syringe to be worn out, and the torsion track will vibrate greatly during the flipping process, which can easily generate bubbles and affect the detection of foreign bodies.

[0005] The patent with application number 202120729558.9 discloses a new disc flipping device for a pre-filled needle light inspection machine, which adopts a gear rack and cam method. The cam drives the rack to move up and down, and the up and down moving rack drives the gear installed on the clamping part to rotate, driving the clamping part to flip, thereby flipping the pre-filled needle; but its structure is complicated, the rack needs to be guided and reset, there are many parts, it is difficult to install and maintain, and the cost is high; and its flipping angle is fixed at the cam stroke. To change the flipping angle, the cam stroke needs to be redesigned. Utility Model Content

DETAILED DESCRIPTION

[0026] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0027] The following is combined with Figure 1-3 This application is described in further detail.

[0028] The present application embodiment discloses a bottle turning device, referring to Figure 1 and Figure 2The bottle turning device includes a clamping mechanism 1, a disc mechanism 2 and a flipping mechanism 3; the clamping mechanism 1 is distributed on the disc mechanism 2 along the circumferential direction, the clamping mechanism 1 includes a base 11 fixed on the disc mechanism 2, a flipping shaft 12 rotatably matched with the base 11, and a clamp 13 arranged on the rotating shaft, the flipping shaft 12 is arranged along the radial direction of the disc mechanism 2, and a driven conical wheel is coaxially fixed on the flipping shaft 12; the flipping mechanism 3 includes a flipping conical wheel coaxially arranged with the disc mechanism 2, the flipping conical wheel is rotationally matched with the disc mechanism 2, and is matched with the driven conical wheel through tooth surface meshing transmission or friction transmission.

[0029] The clamping mechanism 1 is fixed on the rotating disc and connected to the disc mechanism 2 through the flip shaft 12, and the driven conical wheel on the flip shaft 12 cooperates with the flip conical wheel of the flip mechanism 3 to realize the flipping action of the clamping mechanism 1. This setting allows the speed and angle of the flip to be accurately controlled by adjusting the speed difference between the flip mechanism 3 and the disc mechanism 2 during the bottle flipping process, thereby adapting to the detection requirements of prefilled syringes of different types and sizes, ensuring the accuracy and efficiency of the drug detection process. At the same time, this design can also reduce mechanical wear, reduce maintenance costs, and improve the stability and long-term reliability of the device.

[0030] In a specific embodiment, the flip cone wheel is a flip cone gear 31, and the driven cone wheel is a driven cone gear 14. In another specific embodiment, the flip cone wheel and the driven cone wheel are driven by the extrusion friction force of the conical surface. The flip cone wheel is a friction wheel, and the friction wheel and the driven cone wheel are frictionally matched, and the clamping mechanism is driven to flip by friction. When the bevel gear is used, the meshing gear provides accurate flip angle and speed control, ensuring the stability and repeatability of the flipping process. In the embodiment of the cone surface extrusion friction transmission, this non-meshing transmission mode allows sliding when the flipping force exceeds a preset threshold, thereby providing a protection mechanism to avoid excessive flipping or damage to the clamped prefilled syringe. When the driven cone wheel on the clamping mechanism 1 is driven by friction, it is fixedly connected to the flip shaft 12, and the flipping degree of the clamping mechanism 1 is prevented from exceeding the required angle by sliding the flip cone wheel and the driven cone wheel.

[0031] An O-ring 15 is provided between the driven bevel gear 14 and the flip shaft 12, and the driven bevel gear 14 and the flip shaft 12 are connected by the friction force of the O-ring 15. This arrangement allows the driven bevel gear 14 to closely follow the rotation of the flip shaft 12 under normal operating conditions, thereby achieving precise flip control. When the flip force exceeds the friction force that can be provided by the O-ring 15, the driven bevel gear 14 can slide on the flip shaft 12, thereby avoiding mechanical damage or excessive pressure on the clamped object that may be caused by excessive flip force.

[0032] The disc mechanism 2 includes a disc body 21 and a disc shaft 22 coaxially fixedly connected to the disc body 21, and a first gear 23 is connected to the disc shaft 22. The first gear 23 on the disc shaft 22 receives the drive of the power mechanism and effectively transmits the power to the disc body 21 to rotate it.

[0033] The disc shaft 22 is a hollow tube, and a bevel gear shaft 32 is coaxially connected to the flip cone wheel. The bevel gear shaft 32 passes through the center of the disc shaft 22 and rotates with the disc shaft 22. A second gear 33 is provided on the bevel gear shaft 32. With this structure, the bevel gear shaft 32 can rotate independently of the disc shaft 22, and space can be used more effectively.

[0034] Reference Figure 3 , an exhaust channel is provided at one end of the flip shaft 12 close to the chuck 13, and one end of the exhaust channel is located inside the chuck 13 to attract the bottle. When the exhaust channel inside the flip shaft 12 is connected to a negative pressure source, the air is extracted, thereby forming a negative pressure inside the chuck 13, and this negative pressure enables the bottle to be firmly adsorbed on the chuck 13. The advantage of this suction method is that it can achieve contactless clamping of the bottle, reducing the contamination or damage to the bottle that may be caused by physical contact. In addition, this design also allows the bottle turning device to adapt to bottles of different sizes and shapes, thereby improving the versatility of the equipment and the flexibility of operation. By controlling the intensity of the negative pressure in the exhaust channel, the clamping force can be accurately controlled to ensure the stability of the bottle during the flipping process, while facilitating the rapid release of the bottle after the test is completed, thereby improving the efficiency of the entire test process.

[0035] The port of the exhaust channel away from the chuck 13 is opened at the position where the flip shaft 12 is located in the base 11, and a vacuum check valve 4 connected to the port of the exhaust channel away from the chuck 13 is installed on the base 11. The setting of the vacuum check valve 4 ensures that the negative pressure in the exhaust system is transmitted to the chuck 13 through the exhaust channel only when the bottle body needs to be clamped, preventing air pressure leakage in the non-clamping state, thereby improving the suction efficiency and energy saving. At the same time, the check valve can also prevent the negative pressure in the system from disappearing suddenly in power failure or other unexpected situations, avoiding accidental detachment of the bottle body or damage to the equipment due to uncontrolled negative pressure.

[0036] Two sealing rings 5 ​​are arranged between the flip shaft 12 and the base 11, and the port of the exhaust channel away from the chuck 13 is located between the two sealing rings 5. This configuration ensures that the gas in this area of ​​the exhaust channel will not leak to other parts of the device, thereby maintaining the efficiency and accuracy of the exhaust system. The double setting of the sealing ring 5 enhances the sealing performance, effectively prevents external contaminants from entering the exhaust channel or the interior of the flip shaft 12, protects the internal mechanical parts from contamination, and prolongs the service life of the device.

[0037] The bevel gear shaft 32 is hollow, and a first rotary joint 34 is provided at one end of the bevel gear shaft 32, and a second rotary joint 35 is provided at the other end of the bevel gear shaft 32. The first rotary joint 34 is connected to the vacuum check valve 4, and the second rotary joint 35 is used to connect to the vacuum source. Such a design allows negative pressure to be directly transmitted through the inside of the bevel gear shaft 32, thereby realizing efficient integration and power transmission of the vacuum system. The connection between the first rotary joint 34 and the vacuum check valve 4 ensures the sealing and safety of the vacuum system, prevents negative pressure backflow, and facilitates maintenance and inspection. The provision of the second rotary joint 35 enables the vacuum source to be directly connected to the exhaust channel in the flip shaft 12, thereby efficiently providing the necessary negative pressure to the chuck 13 part, ensuring stable adsorption of the bottle body. On the whole, this design simplifies the layout of the vacuum system, reduces the need for additional pipelines, and improves the system's integration and operating efficiency.

[0038] The bottle turning device also includes a mounting seat 6, and the bevel gear shaft 32 is inserted into the mounting seat 6. Bearings are provided between the bevel gear shaft 32 and the mounting seat 6 and between the bevel gear shaft 32 and the disc shaft 22. The main function of this design is to provide stable and smooth rotation support to ensure that the bevel gear shaft 32 can rotate efficiently with minimal friction and wear. The use of bearings reduces friction and heat generation during movement, thereby improving the operating efficiency and life of the entire bottle turning device. In addition, by ensuring the stable positioning of the bevel gear shaft 32 through bearings, the accuracy of power transmission and the precision of mechanical operation can be improved, ensuring the reliability and stability of the turning process, and also facilitating the maintenance of the device and the replacement of bearings.

[0039] The bottle turning mechanism first transports the prefilled syringe to be tested to the machine through a conveyor line and other devices. Once the medicine bottle 7 reaches the working position of the bottle turning device, the clamping mechanism 1 firmly clamps the medicine bottle 7 on the chuck 13 through vacuum adsorption. Then, the disc mechanism 2 starts to rotate, and the clamping mechanism 1 moves along the circumference, driving the medicine bottle 7 to rotate. At the same time, the bevel gear shaft 32 in the turning mechanism 3 is driven by the power mechanism to transmit power to the turning bevel gear 31. The turning bevel gear 31 meshes with the driven conical wheel on the clamping mechanism 1 or cooperates through friction transmission to realize the turning of the medicine bottle 7. By adjusting the speed difference between the turning mechanism 3 and the disc mechanism 2, the turning speed and angle can be accurately controlled to adapt to different specifications and turning requirements of the medicine bottle 7. During the entire turning process, the negative pressure in the exhaust channel keeps the medicine bottle 7 firmly adsorbed on the chuck 13, ensuring that the medicine bottle 7 will not fall off or move during the turning process. Once the bottle body reaches the required turning angle, the turning mechanism 3 stops working, and the medicine bottle 7 is released to the next working stage, such as entering the foreign body detection link. The working process of the entire bottle turning mechanism is efficient and reliable, and can ensure that the medicine bottle 7 is properly turned over during the inspection process, thereby providing accurate data support for subsequent quality inspections and ensuring the quality and safety of the medicines.

[0040] By adjusting the speed difference between the flipping mechanism 3 and the disc mechanism 2, the flipping speed and flipping angle can be adjusted. Flipping at different angles can be achieved without replacing parts, and the number of parts is small, and the cost and installation and maintenance workload are low. When the speed difference between the flipping mechanism 3 and the disc mechanism 2 is exactly the number of teeth of the small bevel gear, the clamping mechanism 1 rotates one circle and flips 360°. In order to avoid transmission loss caused by friction transmission, the flipping degree is generally greater than 360°.

[0041] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
