Description

Technical Field

[0001] The utility model relates to the technical field of medical product detection equipment, in particular to a double-dial feeding device for an infusion bottle and a detection system. Background Art

[0002] In the field of pharmaceutical production, it is usually necessary to conduct sealing tests on drug packaging bottles to ensure that the drugs in the bottles can be safely stored. If the packaging bottle leaks, oxygen, water vapor and microorganisms in the air may invade the packaging bottle, causing the drugs to be oxidized, hydrolyzed, damp or contaminated by microorganisms, thereby affecting the quality and safety of the drugs.

[0003] Related art exists for high-frequency, high-voltage detection devices for bottle leaks. These devices apply a high-frequency, high-voltage electric field to the outside of the bottle being tested and observe changes in the electric field distribution and current to determine if the bottle is leaking. When the bottle is well-sealed, the high-frequency, high-voltage electric field cannot penetrate the bottle wall, resulting in a uniform electric field distribution and low current. However, when the bottle is leaking, the high-frequency, high-voltage electric field penetrates the leak point, causing a change in the electric field distribution and a significant increase in current. However, these related art high-frequency, high-voltage detection devices can cause severe deformation and unstable feeding of the bottle body when it enters the inspection station.

Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0032] The embodiment of the present application provides an infusion bottle double dial feeding device and detection system. Figures 1 to 5 , the double-dial feeding device and detection system for infusion bottles provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0033] The present application discloses a dual-dial feeding device for infusion bottles, which can realize the equal spacing of infusion bottles before they enter the inspection station, so as to improve the accuracy and stability of the inspection station. Figure 1 and Figure 2The double-dial feeding device for infusion bottles includes a conveying track 100, a first dial 200, a second dial 300 and a position sensor 400. Along the conveying direction of the conveying track 100, the first dial 200 is rotatably arranged on the first side of the conveying track 100, and the second dial 300 is rotatably arranged on the second side of the conveying track 100, and the second dial 300 is arranged upstream of the first dial 200. The diameter of the first dial 200 is larger than the diameter of the second dial 300. Part of the conveying track 100 surrounds the first dial 200. The infusion bottles conveyed along the conveying track 100 pass through the second dial 300 and the first dial 200 in sequence before being conveyed to the inspection station.

[0034] In the embodiment of the present application, the first dial 200 is provided with first shift teeth 210 distributed along its circumference, and the first dial 200 forms a first accommodating recess 220 between two adjacent first shift teeth 210. The first accommodating recess 220 is recessed toward the radial inner side of the first dial 200. When the first dial 200 dials an infusion bottle 500, part of the infusion bottle 500 is located in the first accommodating recess 220 and abuts against the first shift teeth 210. The first shift teeth 210 are used to dial the infusion bottle 500 to move along the conveying track 100.

[0035] In the embodiment of the present application, the second dial 300 is provided with second shift teeth 310 distributed along its circumference. The second dial 300 forms a second accommodating recess 320 between two adjacent second shift teeth 310. The second accommodating recess 320 is recessed radially inwardly of the second dial 300. When the second dial 300 stores an infusion bottle 500, part of the infusion bottle 500 is located in the second accommodating recess 320 and abuts against the second shift teeth 310. The second shift teeth 310 are used to drive the infusion bottle 500 to move along the conveying track.

[0036] Please continue to see Figure 1 and Figure 2Along the conveying direction of the conveyor track 100, the second dial 300 is located upstream of the first dial 200. That is, when the infusion bottle 500 is conveyed along the conveyor track 100, the second dial 300 contacts the infusion bottle 500 before the first dial 200. The position sensor 400 is fixedly disposed adjacent to the first dial 200 and the second dial 300. For example, the position sensor 400 may be disposed on the conveyor track 100 or on the frame (not shown) of the dual-dial feeding device, although this embodiment does not impose any specific limitations thereon. In this embodiment, the position sensor 400 is distributed at the intersection of the first dial 200 and the second dial 300. Exemplarily, the position sensor 400 can be a photoelectric sensor. The position sensor 400 is used to detect whether the second shift tooth 310 has an infusion bottle 500. When the second shift tooth 310 has an infusion bottle 500 and the first shift tooth 210 rotates adjacent to the infusion bottle 500, the second dial 300 is configured to rotate to release the infusion bottle 500. When the second dial 300 rotates to release the infusion bottle 500, the infusion bottle 500 moves along the conveying track 100 until it is separated from the second dial 300, so that the first shift tooth 210 that rotates adjacent to the infusion bottle 500 is smoothly handed over to the infusion bottle 500, and drives the infusion bottle 500 to continue moving along the conveying track 100 to the detection station.

[0037] It can be understood that the dual-dial feeding device for infusion bottles should also include a first driving member 910 and a second driving member 920, wherein the first driving member 910 is connected to the first dial 200 to drive the first dial 200 to rotate, and the second driving member 920 is connected to the second dial 300 to drive the second dial 300 to rotate. Exemplarily, the first driving member 910 and the second driving member 920 can be motors. The first driving member 910 or the second driving member 920 can be directly connected to the first dial 200 or the second dial 300, or can be connected to the first dial 200 or the second dial 300 through a transmission mechanism. Exemplarily, the transmission mechanism can be a gear transmission mechanism or a belt transmission mechanism, and this application does not impose specific restrictions on this.

[0038] It should be noted that the double-dial feeding device for infusion bottles also includes a controller. The aforementioned position sensor 400, the first drive member 910 and the second drive member 920 are all electrically connected to the controller. When the position sensor 400 detects that the second shift tooth 310 has shifted the infusion bottle 500, the controller receives the detection signal of the position sensor 400 and controls the action of the first drive member 910 and the second drive member 920. Specifically, the controller can control the first dial 200 to rotate continuously. When the second dial 310 stores an infusion bottle 500, if the first dial 210 is not adjacent to the infusion bottle 500, the second dial 300 is controlled to stop rotating. If the first dial 210 is adjacent to the infusion bottle 500, the second dial 300 is controlled to rotate so that the second dial 300 can smoothly transfer the stored infusion bottle 500 to the first dial 200. That is to say, in the embodiment of the present application, compared with the continuous rotation of the first dial 200, the second dial 300 rotates intermittently, and whether it rotates depends on whether the first dial 210 rotates to the adjacent stored infusion bottle 500.

[0039] When the first dial 200 is in the process of being transported to the storage tank 100, the second dial 300 can be used to transport the infusion bottle 500 to the storage tank 100, thereby preventing the infusion bottle 500 from being directly transported to the first dial 200 and causing the first dial 200 to deliver two materials at a time, thereby preventing two adjacent infusion bottles 500 from being squeezed and damaged. When the first gear 210 of the first dial 200 rotates to be adjacent to the blocked infusion bottle 500, the second dial 300 rotates to release the blocked infusion bottle 500, so that the first gear 210 can smoothly deliver the released infusion bottle 500, thereby enabling the first dial 200 to deliver a single infusion bottle 500 to the subsequent inspection station, thereby preventing the occurrence of double feeding or drug dumping, thereby ensuring the accuracy and stability of the subsequent inspection station inspection.

[0040] It can be understood that, based on the fact that the first dial 200 and the second dial 300 are distributed on both sides of the conveying track 100, the rotation direction of the first dial 200 needs to be opposite to the rotation direction of the second dial 300 in order to realize the infusion bottle 500 being conveyed in the same direction. For example, see Figure 1 , the rotation direction of the first dial 200 is counterclockwise, and the rotation direction of the second dial 300 is clockwise.

[0041] In the embodiment of the present application, the radial depth of the second accommodating recess 320 gradually decreases along the rotation direction of the second dial 300. Under such a setting, when the infusion bottle 500 is conveyed to the second dial 300 along the conveying track 100, the outer edge portion of the second accommodating recess 320 with a relatively shallow radial depth can play a stable stopping and limiting role for the infusion bottle 500, preventing the infusion bottle 500 from shaking randomly in the second accommodating recess 320. As the second dial 300 gradually rotates, the radially deeper portion of the second accommodating recess 320 slowly rotates to the position where the infusion bottle 500 is located. At this time, the second shifting tooth 310 is against the infusion, and the radially deeper portion of the second accommodating recess 320 can form a larger gap space for the infusion bottle 500 to pass through. At this time, the second shifting tooth 310 can contact the infusion bottle 500 and drive the infusion bottle 500 to move.

[0042] For further technical solutions, please continue to refer to Figure 1 and Figure 2 The dual-dial feeding device for infusion bottles further includes a first baffle 600, which is fixedly arranged between the first dial 200 and the second dial 300. For example, the first baffle 600 can use the conveying track 100 as an installation base, and the first baffle 600 can be fastened to the conveying track 100 through a threaded connector. The first baffle 600 and the second dial 300 are arranged opposite to each other, and the infusion bottle 500 has a feature portion corresponding to the first baffle 600 and the second dial 300. The second dial 300 and the first dial 200 drive the infusion bottle 500 to move along the conveying track 100 by dialing the feature portion. Exemplarily, the infusion bottle 500 may include a bottle head 510 and a bottle body 520. The characteristic portion may be the bottleneck of the infusion bottle 500. The radial dimension of the bottleneck is smaller than the radial dimension of the bottle head 510 and the radial dimension of the bottle body 520, so that the infusion bottle 500 can be set on the conveying track 100 in a suspended manner. The first dial 200 and the second dial 300 move the bottleneck to drive the infusion bottle 500 to move along the conveying track 100.

[0043] In the embodiment of the present application, when the second shift tooth 310 is opposite to the first baffle 600, a first gap is formed between the second shift tooth 310 and the first baffle 600, and the width of the first gap is smaller than the radial dimension of the characteristic portion. In this way, when the infusion bottle 500 moves along the conveying track to the second dial 300, the second shift tooth 310 and the first baffle 600 can limit the infusion bottle 500. At this time, the infusion bottle 500 remains in the second accommodating recess 320 and is detected and identified by the position sensor 400. That is to say, when the first shift tooth 210 of the first dial 200 does not rotate to be adjacent to the infusion bottle 500, the second dial 300 does not rotate at this time, and the second dial 300 and the first baffle 600 block the infusion bottle 500.

[0044] When the position sensor 400 detects that the first shifting tooth 210 of the first dial 200 has rotated adjacent to the infusion bottle 500, the controller can control the second dial 300 to rotate, causing the second accommodating recess 320 to face the first baffle 600, thereby releasing the stored infusion bottle 500. Specifically, when the second accommodating recess 320 faces the first baffle 600, a second gap is formed between the outer edge of the second accommodating recess 320 and the first baffle 600. The width of the second gap is greater than the radial dimension of the characteristic portion. In this case, the second gap allows the characteristic portion of the infusion bottle 500 to pass through. As the second dial 300 rotates, the second shifting tooth 310 shifts the infusion bottle 500 forward and transfers it to the first dial 200.

[0045] The second accommodating recess 320 has a smaller extension length in the circumferential direction of the second dial 300 than the radial dimension of the bottle body 520, and the spacing between two adjacent second shifting teeth 310 in the circumferential direction of the second dial 300 is larger than the radial dimension of the bottle body 520. With such a configuration, when an infusion bottle 500 is stored in the second dial 300, the bottle body 520 of the infusion bottle 500 located in the second accommodating recess 320 can abut and repel the bottle body of the subsequent infusion bottle 500, so that the second accommodating recess 320 can only accommodate the characteristic portion of one infusion bottle 500, thereby preventing the second dial 300 from delivering double materials. The size of the bottle body 520 is smaller than the spacing between two adjacent second shifting teeth 310 in the circumferential direction of the second dial 300, thereby avoiding interference with the subsequent infusion bottle 500 being stored in the second dial 300, thereby preventing double feeding and mutual interference.

[0046] In a further technical solution, a first accommodating recess 220 is formed between two adjacent first shifting teeth 210, and the radial dimension of the bottle body 520 is smaller than the extension length of the first accommodating recess 220 in the circumferential direction of the first dial 200. In this way, when the first dial 200 continuously shifts and stores multiple infusion bottles 500 and transports them along the conveying track 100 to the inspection station, it is possible to avoid collision and squeezing of two adjacent infusion bottles 500 shifted by the first dial 200.

[0047] See Figure 1The dual-dial feeding device for infusion bottles of the present embodiment may further include a floating assembly, which may be mounted on the conveyor track 100 or the aforementioned frame. For ease of description, this embodiment will be described with the floating assembly mounted on the conveyor track 100. The floating assembly is configured to apply an elastic force to the infusion bottle 500, causing the infusion bottle 500 to abut against the first dial 200 after being released by the second dial 300. After the infusion bottle 500 is released by the second dial 300, the floating assembly applies a certain elastic force to the infusion bottle 500, ensuring that the infusion bottle 500 is closely attached to the outer periphery of the first dial 200 during the transfer process. This effectively reduces shaking of the infusion bottle 500 caused by external interference, allowing the first shifting tooth 210 to stably contact the feature portion and shift the infusion bottle 500, thereby ensuring stability and accuracy of the infusion bottle 500 during the transfer process. At the same time, reducing the shaking of the infusion bottle 500 through the floating component can not only improve the transportation efficiency, but also effectively prevent the infusion bottle 500 from tipping over during the handover process, and at the same time reduce the risk of damage or leakage of the infusion bottle 500 caused by shaking.

[0048] In an optional embodiment of the present application, the floating assembly includes an elastic member (not shown in the figure) and a second baffle 720, wherein one end of the second baffle 720 can be rotatably set on the conveying track 100, and the other end of the second baffle 720 is slidingly engaged with the conveying track 100, that is, the second baffle 720 is floatingly set on the conveying track 100 in a swinging manner, and the elastic member can be a torsion spring, which is sleeved on the rotating shaft of the second baffle 720, one end of the torsion spring is connected to the second baffle 720, and the other end of the torsion spring is connected to the conveying track 100. Under the elastic force of the torsion spring, the second baffle 720 is pressed against the infusion bottle 500 so that it rests against the outer edge of the first dial 200. In this embodiment, the second baffle 720 is in a swinging form, and the rotating end of the second baffle 720 is located upstream of the conveying track 100 compared to its sliding end. In this way, when the infusion bottle 500 enters the area where the second baffle 720 is located, it can effectively avoid collision and interference with the second baffle 720. The swinging method can adapt to infusion bottles 500 of different sizes. When applied to infusion bottles of various specifications, there is no need to replace different components for complicated adjustments. It can also ensure that the second baffle 720 has a stable contact force on the infusion bottle 500, which is conducive to improving the versatility and reliability of the infusion bottle double dial feeding device.

[0049] For further technical solutions, see Figure 4 and Figure 5The dual-dial feeding device for infusion bottles may further include a transfer conveyor line (not shown) and a lifting mechanism 800. The transfer conveyor line is located upstream of the conveying track 100 and is used to transport and transfer the infusion bottles 500 to the conveying track 100. For example, the transfer conveyor line may be a conveyor belt, and the infusion bottles 500 are supported and transported on the transfer conveyor line. The lifting mechanism 800 is coupled to the transfer conveyor line to drive the transfer conveyor line up or down. For example, the lifting mechanism may be a screw lifting mechanism that can achieve manual or electric adjustment to achieve the raising or lowering of the conveying track 100. This embodiment does not impose specific limitations on this. For infusion bottles 500 of different sizes and types, the lifting mechanism 800 can be used to lift or lower them so that the height position of their characteristic parts can correspond to the first dial 200 and the second dial 300, thereby improving the compatibility of the entire dual-dial feeding device for infusion bottles.

[0050] In the examples of this application, see Figure 4 The conveying track 100 includes an outer guard plate 110 and a support plate 120 connected to the outer guard plate 110. The support plate 120 is distributed on the inner side of the outer guard plate 110. The bottle head 510 of the infusion bottle 500 can be suspended and supported on the support plate 120. In the height direction, the upper surface of the support plate 120 is slightly lower than the upper surface of the outer guard plate 110, so that the conveying track 100 forms a track groove on its inner side for the infusion bottle 500 to pass through, so that the infusion bottle 500 can move forward stably under the driving of the second dial 300 and the first dial 200. The aforementioned position sensor 400, floating assembly, etc. can be installed on the outer guard plate 110.

[0051] The embodiment of the present application further discloses a detection system for performing leakage detection on an infusion bottle 500 , and the detection system includes the aforementioned double-dial feeding device for infusion bottles.
