Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic bottle testing equipment, and in particular to a pharmaceutical packaging bottle testing system. Background Technology
[0002] In the production of pharmaceutical packaging bottles, the bottle's sealing performance, cap forming quality, and cleanliness directly affect drug safety. Currently, most companies use leak detectors to test the airtightness of plastic bottles. However, this equipment can only judge sealing performance through changes in air pressure and cannot identify physical defects such as thread defects, bottle deformation, and black spots, often requiring manual visual inspection. However, relying solely on manual inspection is prone to worker fatigue, leading to errors or the inability to identify black spots. Furthermore, manual inspection is too slow; even with high-speed plastic bottle production, only random sampling is possible, resulting in low efficiency. Inspecting each bottle individually would require a large number of workers, undoubtedly increasing company costs. Therefore, there is an urgent need to develop an integrated system for sealing performance testing and three-dimensional defect identification to solve these problems. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0033] Please see Figures 1-4 The pharmaceutical packaging bottle inspection system of this embodiment includes: a frame 10, a first transport device 20, a second transport device 30, a third transport device 40, an airtightness inspection device 50, a bottle bottom inspection device 60, a bottle interior inspection device 70, a bottle body inspection device 80, an induction trigger module 90, and a rejection device 100.
[0034] The frame 10 is constructed from standard aluminum profiles welded together. Along the material feeding direction, the frame 10 is sequentially equipped with a first conveying device 20, a second conveying device 30, and a third conveying device 40. An airtightness detection device 50 is positioned above the second conveying device 30 and mounted on the frame 10; it is used to detect the airtightness of the plastic bottles. A bottle bottom detection device 60 is positioned below the second conveying device 30 and mounted on the frame 10; it is used to detect the appearance integrity of the bottle bottom. An internal bottle detection device 70 and a body bottle detection device 80 are sequentially positioned above the third conveying device 40 and mounted on the frame 10 along the material feeding direction; they are used to detect the appearance integrity of the internal parts and the body of the plastic bottles, respectively. The first conveying device 20, the second conveying device 30, and the third conveying device 40 work together to transport the plastic bottles in stages, completing corresponding detection tasks during the transportation process to ensure the continuity of the plastic bottle production line.
[0035] The sensing trigger module 90 includes sensing triggers A91, B92, and C93, which are respectively located on the rear side of the airtightness detection device 50, the bottle interior detection device 70, and the bottle body detection device 80 along the material feeding direction. Sensing trigger A91 is communicatively connected to both the airtightness detection device 50 and the bottle bottom detection device 60; sensing trigger B92 is communicatively connected to the bottle interior detection device 70; and sensing trigger C93 is communicatively connected to the bottle body detection device 80. The sensing trigger module 90 is used to sense whether the plastic bottle is about to pass through the corresponding detection device and triggers the detection device to perform the detection operation.
[0036] Three rejection devices 100 are provided, which are respectively set for the bottle bottom detection device 60, the bottle inside detection device 70 and the bottle body detection device 80, and are arranged in front of the bottle bottom detection device 60, the bottle inside detection device 70 and the bottle body detection device 80 along the material feeding direction. The three rejection devices 100 are connected to an external control unit and are used to reject the defective products detected by the corresponding detection devices and remove the defective products from the transport device.
[0037] The following is a further explanation of each part:
[0038] The first transport device 20 is a roller-type flat transport belt. The first transport device 20 includes two driving rollers at both ends and a belt wound between the rollers. One of the driving rollers is connected to a drive motor. Guide plates are symmetrically installed on the first transport device 20. The two guide plates cooperate to form a Y-shaped channel. Only one plastic bottle can pass through the front end of the channel, which facilitates the subsequent inspection of plastic bottles one by one.
[0039] The second transport device 30 includes mounting plates 31, arranged in pairs. Two sets of mounting plates 31 are symmetrically mounted on both sides of the frame 10. In this embodiment, the mounting plates 31 are mounted on the inflation unit mounting frame 51 (described later) via support rods. Two driven gears 34 are spaced apart between each set of mounting plates 31. A toothed belt 35 is wound around the two driven gears 34, and the inner side of the toothed belt 35 meshes with both driven gears 34. A motor 32 is fixedly mounted on the end face of the upper mounting plate 31 in each set. The output shaft of the motor 32 passes through the mounting plate 31 and is fixedly sleeved with a driving gear 33, which meshes with one of the driven gears 34. When the motor 32 is started, the driving gear 33 meshes with the driven gear 34, causing the driven gear 34 to rotate, thereby rotating the toothed belt 35. When the plastic bottle enters the second transport device 30 via the first transport device 20, it is held and moved forward by the toothed belts 35 on both sides.
[0040] The airtightness testing device 50 and the bottle bottom testing device 60 are arranged sequentially corresponding to the second transport device 30. They test the appearance of the bottle bottom while testing the airtightness of the plastic bottle to ensure the synchronization of the testing. The airtightness testing device 50 includes a welded inflation unit mounting frame 51 as a support base. The bottom two sides of the inflation unit mounting frame 51 are fixedly welded to the frame 10. An inflation unit 54 and a linear guide rail 52 are fixedly mounted on the top of the inflation unit mounting frame 51. A guide rail slider 53 is slidably mounted on the linear guide rail 52. A cylinder 55 is fixedly connected to the bottom of the guide rail slider 53. An inflation nozzle 56 is fixedly mounted on the movable end of the cylinder 55. The inflation unit 54 is connected to the inflation nozzle 56 through a flexible conduit and is used to provide an air source to the inflation nozzle 56. It should be noted that the above structure is the core structure for the detection of air tightness of plastic bottles in this detection system. It is implemented with reference to the leak detector in the prior art. Other functional components of the leak detector (such as air pressure sensing module, air compressor, etc.) are all located in the inflation unit 54, and are not shown one by one for the sake of brevity.
[0041] The bottle bottom detection device 60 includes a welded camera A mounting frame 61. The camera A mounting frame 61 is fixedly welded to the frame 10 on both sides, and a camera A mounting platform 62 is mounted on its bottom. A camera A63 and a supplementary light A64 are fixedly mounted on the upper surface of the camera A mounting platform 62. The camera A63 and the supplementary light A64 are used to photograph the bottom of the plastic bottle and provide the light source required for the photographing, respectively. Specifically, the supplementary light A64 can be a ring light to ensure that the light source is evenly projected onto the plastic bottle. Preferably, a transparent plate is sandwiched between the airtightness detection device 50 and the bottle bottom detection device 60 to prevent the plastic bottle from falling during transport by the second transport device 30.
[0042] Please see Figure 4The structure of the third transport device 40 is essentially the same as that of the first transport device 20, except that the belt in the third transport device 40 is designed to have a different length than the belt in the first transport device 20 in actual application.
[0043] The bottle interior detection device 70 and the bottle body detection device 80 are arranged sequentially corresponding to the third transport device 40. The bottle interior detection device 70 includes a camera B mounting frame 71, which is fixedly welded to the frame 10 on both sides. A camera B mounting platform 72 is installed on the top of the camera B mounting frame 71. A camera B 73 and a fill light B 74 are fixedly installed on the lower end face of the camera A mounting platform 62. The camera B 73 and the fill light B 74 are used to take pictures of the inside of the plastic bottle and provide the light source required for taking pictures, respectively. Specifically, the fill light B 74 is also a ring light.
[0044] The bottle detection device 80 includes four cameras C82, which are symmetrically arranged in pairs on both sides of the frame 10. The cameras C82 are fixedly mounted on the frame 10 via camera C brackets 81. They are used to photograph the body of the plastic bottle. Preferably, the two cameras C82 in each pair are arranged at a 70°-90° angle to each other to ensure omnidirectional, blind-spot-free photography. Simultaneously, a supplementary light C83 is provided between each pair of cameras C82, and the supplementary light C83 is fixedly mounted on the frame 10. Specifically, the supplementary light C83 can be a surface light.
[0045] Preferably, all of the aforementioned cameras A, B, and C can be high-definition cameras.
[0046] Preferably, the induction triggers A91, B92, and C93 in the induction trigger module 90 have the same structure and can all be photoelectric sensors. Each photoelectric sensor includes an optical transmitter and an optical receiver, which are arranged opposite to each other. Induction trigger A91 is installed on the rear side of the two sets of mounting plates 31, while induction triggers B92 and C93 are directly mounted on the frame 10.
[0047] Preferably, the rejection device 100 includes an automatic rejector 101 and a receiving trough 102 symmetrically arranged on both sides of the frame 10. The automatic rejector 101 and the receiving trough 102 are fixedly installed on the frame 10. The receiving trough 102 is rectangular and has a discharge port on the side opposite to the automatic rejector 101. The automatic rejector can be a pneumatic rejector or a push rod rejector. The plastic bottles are pushed by the automatic rejector 101 and fall out of the receiving trough 102, which facilitates the classification and collection of defective products.
[0048] The testing process for this utility model is as follows:
[0049] When the plastic bottle enters the second transport device 30 from the first transport device 20, it passes through the induction trigger A91. The induction trigger A91 generates an induction signal and transmits the signal to the airtightness detection device 50 and the bottle bottom detection device 60. The airtightness detection device 50 and the bottle bottom detection device 60 work simultaneously. In the airtightness detection device 50, the guide rail slider 53 drives the cylinder 55 and the inflation nozzle 56 to reciprocate. First, it moves in the same direction as the plastic bottle. At this time, the cylinder 55 drives the inflation nozzle 56 to move down and cover the mouth of the plastic bottle to inflate it inward to check the airtightness of the plastic bottle. After the test is completed, the inflation stops, the cylinder 55 quickly retracts, and the slider 53 quickly resets to wait for the next plastic bottle to pass. At the same time, the supplementary light device A64 of the bottle bottom detection device 60 starts to supplement the light, and the camera A63 takes an image of the bottle bottom. The acquired image can be transmitted to the external control unit for comparison and analysis to determine whether it is intact. If a defective product is detected during the process (the plastic bottle does not meet the airtightness standard or there is a defect at the bottom of the bottle), the control unit sends a rejection signal to the rejection device 100 located in front of the bottle bottom detection device 60 to reject the plastic bottle.
[0050] If the plastic bottle passes the aforementioned inspection, it continues to be transported to the third transport device 40. Similarly, the induction trigger B92 generates an induction signal and transmits it to the bottle-in-detection device 70. The supplementary light device B74 starts to provide supplementary light, and the camera B73 captures an image of the inside of the plastic bottle as it passes by. Defective products are rejected by the rejection device 100 in front of the bottle-in-detection device 70. Qualified products continue to be transported. The induction trigger C93 generates an induction signal and transmits it to the bottle-body detection device 80. The supplementary light device C83 starts to provide supplementary light, and the camera C82 captures an image of the bottle body as it passes by. Defective products are rejected by the rejection device 100 in front of the bottle-body detection device 80. Qualified products are then inspected, transported, and discharged.
[0051] Of course, the design and creation of this utility model are not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
