Description

Technical Field

[0001] The present invention relates to the technical field of food and drug packaging machinery and equipment, and particularly to a bottle leakage detection device. Background Art

[0002] Regarding the detection of glass bottle aqueous medicines in the current market, for the requirements of large specification spans and compatibility of multiple packaging material product types on one device, the traditional structure of multiple sets of detection modules is shared, and it is necessary to replace detection modules of different specifications, with poor adaptability; and it involves the cooperation of the auger conveying pitch and the detection electrode. During the process of the medicine bottle passing through the detection station, due to too large a pitch, the bottle running is unstable, the risk of broken bottles is high, and the detection is affected. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a bottle leakage detection device with a simple structure, strong adaptability and capable of avoiding the problem of indistinguishable separation.

[0004] To solve the above technical problem, the present invention adopts the following technical solutions:

[0005] A bottle leakage detection device includes a conveying guide rail and a bottle conveying auger arranged on the conveying guide rail. One side of the conveying guide rail facing the bottle conveying auger is provided with a detection station. A high-voltage electrode and a low-voltage electrode are arranged on the detection station. The high-voltage electrode and the low-voltage electrode are respectively located on both sides of the conveying guide rail and are arranged opposite to each other. The low-voltage electrode is divided into at least two segments.

[0006] As a further improvement of the above technical solution:

[0007] The total length of each segment of the low-voltage electrode is shorter than the length of the high-voltage electrode.

[0008] The two ends of the low-voltage electrode and the high-voltage electrode are flush.

[0009] The length of each segment of the low-voltage electrode is set to S, and the pitch of the bottle conveying auger is set to f, and S < f.

[0010] The length of the high-voltage electrode is set to L, and the diameter of the bottle is set to D, and πD ≤ L.

[0011] There is a gap H between adjacent segments of the low-voltage electrode, and 0 < H ≤ 5 mm.

[0012] H = 2 mm.

[0013] Compared with the prior art, the advantages of the present invention are as follows:

[0014] The bottle leakage detection device of the present invention has the following detection process: the bottle rolls forward along the conveying guide rail under the rotation and pushing action of the bottle conveying auger, and when the bottle passes between the relative high-voltage electrode and the low-voltage electrode, the current passing through the bottle is used to detect whether there is leakage at various places of the bottle. Since relative high-voltage electrodes and low-voltage electrodes are used, and the low-voltage electrode is divided into at least two sections, if a larger-sized bottle needs to be detected, and the original single pair of high-voltage electrodes and low-voltage electrodes cannot fully detect the bottle because their length is less than the circumference of the bottle, at this time, the same pair or more pairs of high-voltage electrodes and low-voltage electrodes can be added before or after the original single pair of high-voltage electrodes and low-voltage electrodes, so that the total length of each high-voltage electrode is greater than or equal to the circumference of the bottle to achieve complete detection. Bottles of different specifications can be adapted by simply adding or subtracting paired high-voltage electrodes and low-voltage electrodes, and the adaptability is strong. At the same time, if the pitch of the bottle conveying auger is to be shortened while keeping the original high-voltage electrode length unchanged, for example, the original high-voltage electrode length is equal to twice the pitch of the bottle conveying auger, then, if the low-voltage electrode is not segmented, it will cause one low-voltage electrode to pass through two bottles at the same time, and the current passing through the high-voltage electrode and the low-voltage electrode is the sum of the currents of the two bottles. If one bottle leaks, it is impossible to distinguish which bottle is leaking through the electrode current. Therefore, the low-voltage electrode is divided into at least two sections, which can avoid the problem of indistinguishability. The bottle leakage detection device has a simple structure, strong adaptability, and can avoid the problem of indistinguishability. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Figures 1 to 4An embodiment of the bottle leakage detection device of the present invention is shown. The bottle leakage detection device includes as Figure 1 and Figure 2 shown. The bottle leakage detection device of this embodiment includes a conveying guide rail 1 and a bottle conveying auger 2 provided on the conveying guide rail 1. A detection station 3 is provided on one side of the conveying guide rail 1 facing the bottle conveying auger 2. A high-voltage electrode 4 and a low-voltage electrode 5 are provided at the detection station 3. The high-voltage electrode 4 and the low-voltage electrode 5 are respectively located on both sides of the conveying guide rail 1 and are arranged opposite to each other. The low-voltage electrode 5 is divided into at least two segments.

[0023] Detection process: Under the rotational pushing action of the bottle conveying auger 2, the bottle 6 rolls forward along the conveying guide rail 1. When the bottle 6 passes between the opposite high-voltage electrode 4 and low-voltage electrode 5, the current passing through the bottle 6 is used to detect whether there are leaks at various parts of the bottle 6. Since the opposite high-voltage electrode 4 and low-voltage electrode 5 are adopted, and the low-voltage electrode 5 is divided into at least two segments, in this way, if a larger-sized bottle 6 needs to be detected, and the original single pair of high-voltage electrode 4 and low-voltage electrode 5 has a length less than the circumference of the bottle 6, thus it cannot completely detect the bottle 6. At this time, the same pair or multiple pairs of high-voltage electrode 4 and low-voltage electrode 5 can be added in front of or behind the original single pair of high-voltage electrode 4 and low-voltage electrode 5, so that the total length of each high-voltage electrode 4 is greater than or equal to the circumference of the bottle 6 to achieve complete detection. As long as the paired high-voltage electrode 4 and low-voltage electrode 5 are increased or decreased, it can adapt to bottles 6 of different specifications, with strong adaptability. At the same time, when keeping the length of the original high-voltage electrode 4 unchanged, if the pitch of the bottle conveying auger 2 is to be shortened, for example, making the length of the original high-voltage electrode 4 equal to twice the pitch of the bottle conveying auger 2, in this way, if the low-voltage electrode 5 is not segmented, there will be two bottles 6 passing through one low-voltage electrode 5 at the same time, and the current passing through the high-voltage electrode 4 and the low-voltage electrode 5 is the sum of the currents of the two bottles. If one of the bottles has a leak, it is impossible to distinguish which bottle 6 has a leak through the electrode current. Therefore, the low-voltage electrode 5 being divided into at least two segments can avoid the problem of indistinguishable. This bottle leakage detection device has a simple structure, strong adaptability and can avoid the problem of indistinguishable.

[0024] One pair or multiple pairs of high-voltage electrode 4 and low-voltage electrode 5 are provided at the detection station 3. The conveying guide rail 1 is provided with one detection station 3 or multiple detection stations 3 along the conveying direction.

[0025] In this embodiment, as Figure 2 and Figure 4 shown, the total length of each segment of the low-voltage electrode 5 is shorter than the length of the high-voltage electrode 4.

[0026] In this embodiment, the two ends of the low-voltage electrode 5 and the high-voltage electrode 4 are flush. The number of segments of the low-voltage electrode 5 is set to m, the length of each segment of the low-voltage electrode 5 is set to S, the length of the high-voltage electrode 4 is set to L, there is a spacing H between adjacent segments of the low-voltage electrode 5, and L = mS+(m - 1)H. In this way, when the bottle body 6 passes between the paired high-voltage electrode 4 and low-voltage electrode 5, the head and tail of the bottle body 6 are in contact with the high-voltage electrode 4 and the low-voltage electrode 5 respectively. If the high-voltage electrode 4 is longer than the low-voltage electrode 5, when the extended segment contacts the head of the bottle body 6, there will be no low-voltage electrode 5 in contact with the tail of the bottle body 6. In this way, it will cause waste of the high-voltage electrode 4.

[0027] In this embodiment, as Figure 2 shown, the length of each segment of the low-voltage electrode 5 is set to S, and the pitch of the bottle body conveying auger 2 is set to f, where S < f. Ensure that there will not be two bottle bodies 6 passing through each segment of the low-voltage electrode 5 at the same time, avoiding the problem of indistinguishable separation.

[0028] In this embodiment, the length of the high-voltage electrode 4 is set to L, and the diameter of the bottle body 6 is set to D, where πD ≤ L. In this way, after the bottle body 6 passes through a pair of high-voltage electrode 4 and low-voltage electrode 5, complete detection can be achieved, completely avoiding the phenomenon of missed detection.

[0029] In this embodiment, there is a spacing H between adjacent segments of the low-voltage electrode 5, where 0 < H ≤ 2 mm. Optimally, H = 2 mm.

[0030] Assume: The diameter of the bottle body 9 is 22 mm, then the circumference πD = 3.14 x 22 = 69.08 mm, and half of the circumference is 69.08 / 2 = 34.54;

[0031] When the pitch f of the bottle body conveying auger 2 is designed to be greater than 40 mm, the length of each segment of the low-voltage electrode 5 is 39 mm, and the spacing H between adjacent segments of the low-voltage electrode 5 = 2 mm. The bottle body 6 rolls on the front segment of the low-voltage electrode 5, and the front segment of the low-voltage electrode 5 can cover more than half of the circumference of the bottle body 6. Then the bottle body 6 rolls on the rear segment of the low-voltage electrode 5 for more than half of the circumference of the bottle body 6. Each bottle body 6 passes through two segments of the low-voltage electrode 5, and the bottle body 6 can be detected in one circle, so that every part of the bottle body 6 can be detected. And at any time, there can only be one bottle body 6 on each segment of the low-voltage electrode 5;

[0032] When keeping the length of the original high-voltage electrode 4 (80 mm) unchanged, if it is necessary to shorten the pitch of the bottle body conveying auger 2. For example, make the pitch f of the bottle body conveying auger 2 = 20 mm. In this way, there are always two bottles on the low-voltage electrode 5. Then the electrode current is the sum of the currents of the two bottle bodies 6. If there is a leakage in one bottle, it is impossible to distinguish which bottle body 6 has the leakage through the electrode current;

[0033] When the length L of the high-voltage electrode 4 is 40 mm < 69.08 mm, at any moment, only one bottle body 6 exists on the high-voltage electrode 4 and each section of the low-voltage electrode 5. The leakage of the bottle body 6 can be judged by the return electrode current. However, the diameter of the bottle body 6 is 22 mm, so the circumference πD = 3.14 x 22 = 69.08 mm. Any bottle body 6 cannot roll 360° on the electrode, and complete detection cannot be achieved.

Any person skilled in the art can make many possible changes and modifications to the technical solution of the present invention by using the technical content disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the scope of protection of the technical solution of the present invention.
