Description

Technical Field

[0001] The invention relates to the pharmaceutical field, in particular to a rotary electronic leak detector. Background Art

[0002] In the pharmaceutical field, medicine bottles need to be tested for sealing after production. Currently, the most accurate and reliable detection method is to use an electronic leak detector for sealing detection. However, when the electronic leak detector is working, the medicine bottle is required to be rotated while being detected to ensure that the entire bottle is detected. The common leak detection methods on the market are auger-driven, where the auger is located above or below the medicine bottle and rotates the bottle by the friction of the support plate, or rollers are rolled and the medicine bottle is rotated by friction. For glass bottles with small bottle shape errors, this structure rarely fails to rotate the bottle. However, for some plastic ampoules, flat bottles or molded bottles with irregular shapes, there is a phenomenon of non-rotation.

[0023] A rotary electronic leak detector comprises a frame 1, a bottle feeding mesh belt 2, a rotating disk 4, a bottle discharging mesh belt 3 and a plurality of medicine bottle detection stations, and further comprises a three-dimensional curved slide rail 8 arranged concentrically with the rotating disk on the frame, the bottle feeding mesh belt and the bottle discharging mesh belt are both arranged on the frame and are arranged at intervals on the same horizontal line, a bottle dividing dial wheel 9 and a bottle feeding dial wheel 10 are respectively provided on both sides of one end of the bottle feeding mesh belt close to the bottle discharging mesh belt, the bottle dividing dial wheel and the bottle feeding dial wheel are engaged with each other and the position of the discharge port where the bottle dividing dial wheel and the bottle feeding dial wheel engage is set. There is an arc-shaped guide plate 11 for guiding the medicine bottles.

The feeding port of the bottle-discharging dial wheel is provided with an arc-shaped guide plate 2 for guiding the medicine bottles. At the same time, the bottle-discharging dial wheel rotates clockwise along the conveying direction of the bottle-inlet mesh belt, and the corresponding engaged bottle-inlet dial wheel moves counterclockwise. The bottle-discharging dial wheel moves counterclockwise in the same direction as the bottle-inlet dial wheel. Several bottle clamping devices 5 are provided along the circumference of the rotating disk. Each bottle clamping device is connected to the bottle by a flipping device. The bottle discharging mechanism 14 is a kind of bottle discharging mechanism, and the bottle discharging mechanism 15 is a kind of bottle discharging mechanism, and the bottle discharging mechanism 16 is a kind of bottle discharging mechanism, and the bottle discharging mechanism 17 is a kind of bottle discharging mechanism, and the bottle discharging mechanism 18 is a kind of bottle discharging mechanism, and the bottle discharging mechanism 19 is a kind of bottle discharging mechanism, and the bottle discharging mechanism 20 is a kind of bottle discharging mechanism, and the bottle discharging mechanism 21 is a kind of bottle discharging mechanism, and the bottle discharging mechanism 22 is a kind of bottle discharging mechanism, and the bottle discharging mechanism 14 is a kind of bottle discharging mechanism, and the bottle discharging mechanism 16 is a kind of bottle discharging mechanism, and the bottle discharging mechanism 18 is a kind of bottle discharging mechanism, and the bottle discharging mechanism 19 is a kind of bottle discharging mechanism, and the bottle discharging mechanism 1

[0024] The flipping device includes a support rod 22, a hinge 21 and a roller 20 provided on one side of the support rod. One end of the support rod is hinged to the rotating disk through a hinge. An inner concave annular groove is provided on the outer circumference of the roller. The three-dimensional curved slide rail is clamped in the inner concave annular groove of the roller. At the same time, the roller is driven to extend and retract through a connected reset device so that the roller is always clamped with the three-dimensional curved slide rail when the flipping device is flipped at any angle, thereby driving the flipping device to slide along the set three-dimensional curved slide rail track. The clamping device is provided on the other side of the support rod. The setting direction of the roller and the bottle clamping direction of the bottle clamping device are parallel to the setting direction of the support rod. The clamping device includes a pressure head rod 23, a bottle rotating base 27 and a driving device provided at the bottom of the bottle rotating base. The pressure head rod is connected to the support rod and is connected to a pressure head 26 at one end close to the rotating disk through a bearing 25. The pressure head presses the bottle head of the medicine bottle under the action of a compression spring 24 mounted on the pressure head rod. The compression direction of the compression spring is parallel to the setting direction of the support rod. The bottle rotating base is used to support the bottom of the medicine bottle. The driving device includes a motor 7. The motor is connected to a synchronous pulley 1 30 through a motor shaft. The synchronous pulley 1 drives the synchronous pulley 2 28 to rotate through a synchronous belt 29. The synchronous pulley 2 is connected to the bottle rotating base shaft, so that the flipping device drives the medicine bottle clamped in the upper pressure and lower support manner to flip, and then a separate motor drives the bottle rotating base connected to each shaft, which can avoid speed loss while rotating the medicine bottle accurately, so that medicine bottles of various materials and specifications can be smoothly inspected and missed inspections can be avoided even when the filling volume is very small.

[0025] This embodiment provides three medicine bottle inspection stations: a bottle head inspection station 19, a bottle body inspection station 18, and a bottle bottom inspection station 17. The bottle head inspection station, the bottle body inspection station, and the bottle bottom inspection station are respectively provided with different flipping angles. At the same time, the bottle head inspection station, the bottle body inspection station, and the bottle bottom inspection station are all provided with detection electrodes. The emitter 31 and the receiving electrode 32 on the detection electrode are both located below the medicine bottle to be inspected, which is beneficial to increase the contact area between the medicine liquid and the detection surface when the medicine bottle is flipped.

[0026] During the implementation process, the medicine bottles to be tested are fed through the bottle feeding mesh belt, and the bottle separation dial rotates clockwise to separate the bottles and drive the medicine bottles to rotate forward. At the same time, the bottle feeding dial rotates counterclockwise. Because the bottle separation dial and the bottle feeding dial are engaged, when the bottle separation dial and the bottle feeding dial engage, the medicine bottles are smoothly fed from the bottle separation motor dial to the bottle feeding dial, and then the medicine bottles are fed to the rotating disk through the guidance of the arc-shaped guide plate and the rotation of the bottle feeding dial. Several bottle clamping devices are installed on the rotating disk. The bottle clamping devices are hinged to the rotating disk through the hinges on the flipping device, so that the bottle clamping devices can flip along the radial direction of the rotating disk. When in the bottle in and out position, the bottle clamping devices are upright, and their state is as follows Figure 4 As shown, at this time, the medicine bottle enters, and then the pressure head presses the medicine bottle under the action of the spring. While the rotating disk rotates, it drives the flip device to move along the three-dimensional curved slide through the roller, and the bottle clamping device can be flipped to a certain angle, for example Figure 4The flip shown is 90°, and the angle setting is related to the track setting of the three-dimensional curved slide. During the entire rotation process of the rotating disk, the spatial state of the medicine bottle is changed by changing the three-dimensional curve parameters of the three-dimensional curved slide. The bottle clamping device first flips down along the radial direction of the rotating disk from the upright state of the bottle entering, stops after flipping to a certain angle, and then flips up along the radial direction of the rotating disk until it reaches the upright state when the bottle is discharged. The flip angle can be adjusted according to the specific amount of the medicine bottle, and when it passes through the three inspection stations of the bottle head, bottle body and bottle bottom, the corresponding position of each inspection station is obtained through the three-dimensional curved slide and the flip device. The medicine bottle is tilted at an angle, and at the same time, the motor connected to each bottle clamping device drives the medicine bottle base to rotate, thereby driving the medicine bottle to rotate. The motor speed is adjusted to ensure that the medicine bottle can accurately rotate multiple circles during detection to avoid missed detection. After the detection, the medicine bottle is driven by the rotating disk to drive the medicine bottle on the bottle clamping device into the counterclockwise rotating bottle output dial, and then the medicine bottle is sent to the bottle output mesh belt through the guidance of the arc guide plate 2. At this time, the liquid level detection station performs liquid level identification and detection on the medicine bottle, and the qualified and unqualified medicine bottles are sent to the bottle output mesh belt and the waste chute respectively through the waste rejection device. At this point, the entire detection process is completed.
