TECHNICAL FIELD

[0001] The present application relates to the field of detection equipment, and in particular to a BFS product automatic lamp detection machine. BACKGROUND

[0002] A blow-fill-seal integrated machine (referred to as "BFS") can realize the steps of blow molding, liquid product filling and sealing of a row of ampoules in a sterile state, and is widely used in the packaging production of various liquid medicines and cosmetics.

[0003] In related technologies, after a row of ampoules is produced by a blow-fill-seal integrated machine, a series of detections need to be performed to ensure the integrity of the row of ampoules and the cleanliness of the liquid inside. Currently, the detection of the row of ampoules is mainly performed by manual sampling inspection. When performing the detection, the row of ampoules is stood up and placed under a lamp panel for visual inspection.

[0004] In the above related technologies, on the one hand, manual sampling inspection is usually prone to missed inspection or incorrect inspection, and the detection efficiency is low; on the other hand, since some impurity particles tend to deposit at the bottom of the row of ampoules, when the row of ampoules is stood up and placed at the lamp panel for detection, the specific situation of the liquid in the area cannot be observed, and the situation of the liquid inside the ampoule can be confirmed only after the position of the ampoule is repeatedly adjusted or the ampoule is shaken by hand. Therefore, there is room for improvement. SUMMARY

[0081] The second upright conveying part comprises two second upright conveying belts 422 which form conveying gaps for clamping and conveying the upright array ampoule bottle tails. The input ends and output ends of the two second upright conveying belts 422 are vertically arranged axially. The input ends of the two second upright conveying belts 422 respectively extend to the bottom of the output ends of the two first upright conveying belts 421, so as to realize the butt joint of the first upright conveying part and the second upright conveying part.

[0082] The image acquisition assembly 6 located at the overturning conveying mechanism comprises three parts, two of which are located at the first upright conveying part and one of which is located at the second upright conveying part. The camera 61 of the two image acquisition assemblies 6 located at the first upright conveying part are respectively located at the sides of the two first upright conveying belts 421 which are away from each other and are both arranged towards the conveying path of the array ampoule bottles. The image acquisition assembly 6 located at the second upright conveying part is located at one side of the second upright conveying belt 422 and the camera 61 of the image acquisition assembly 6 at this position is arranged towards the conveying path of the array ampoule bottles.

[0083] Specifically, the camera 61 located at the first upright conveying part is used for shooting and acquiring the image of the upright array ampoule bottle and feeding back to the control module, so as to judge whether there is a defect at the ampoule bottle body and bottle tail, whether there is a floating impurity particle in the liquid in the array ampoule bottle body and whether there is a precipitated impurity at this time.

[0084] The camera 61 located at the second upright conveying part is used for shooting and acquiring the image of the upright array ampoule bottle and feeding back to the control module, so as to judge whether there is a defect at the ampoule bottle body and bottle head, whether there is a floating impurity particle in the liquid in the array ampoule bottle body and whether there is a precipitated impurity at this time.

[0085] The overturning conveying assembly 41 overturns the array ampoule bottle in the inclined state to the upright state. When there is an impurity particle in the array ampoule bottle, it is convenient to better improve the flowability of the impurity particle in the liquid in the array ampoule bottle, so as to make it better be captured by the image acquisition assembly 6. The first upright conveying part and the second upright conveying part clamp and convey the array ampoule bottle head and the array ampoule bottle tail respectively, so that the array ampoule bottle head and the array ampoule bottle tail can be alternately leaked, and then the corresponding image acquisition assembly 6 can more completely acquire the image of the array ampoule bottle.

[0086] The turnover conveying mechanism further comprises a support conveying belt 43 for supporting and conveying the upright arrayed ampoules. The input end of the support conveying belt 43 extends to the bottom of the output end of the two second turnover conveying belts 412, and the output end of the support conveying belt 43 extends to the bottom of the input end of the two first upright conveying belts 421. The support conveying belt 43 is used to assist in conveying the upright arrayed ampoules, which is conducive to better connecting the unpowered area between the second turnover conveying part and the first upright conveying part, and thus facilitating the better transmission of the upright arrayed ampoules output by the second turnover conveying part to the first upright conveying part.

[0087] With reference to Figure 8 and Figure 9 The discharge conveying mechanism 5 comprises a discharge conveying belt 51, and the input end of the discharge conveying belt 51 extends to the bottom of the output end of the two second upright conveying belts 422. A cull assembly 50 is arranged at the input end of the discharge conveying belt 51, and the cull assembly 50 comprises a cull limiting rod 501, a cull air knife 502, and a cull collection box 503. The cull limiting rod 501 is arranged above the discharge conveying belt 51 and leaves a gap with the conveying surface of the discharge conveying belt 51, and the leading end of the cull limiting rod 501 extends to the output end of the second upright conveying part for the head of the upright arrayed ampoule output by the second upright conveying part to be overlapped. The cull air knife 502 and the cull collection box 503 are respectively arranged on the opposite sides of the discharge conveying belt 51, and the cull air knife 502 is arranged towards the gap between the cull limiting rod 501 and the discharge conveying belt 51. The cull air knife 502 is electrically connected with the control module.

[0088] The control module determines the qualification of the arrayed ampoules according to the image acquisition assemblies 6. When the unqualified arrayed ampoules are conveyed to the cull limiting rod 501, the control module controls the cull air knife 502 to blow the unqualified arrayed ampoules into the cull collection box 503, so as to realize the automatic culling of the unqualified arrayed ampoules. In this embodiment, the opening and closing of the cull air knife 502 is completed by the control module in cooperation with the sensor.

[0089] The second guide 52 is further arranged on the discharge conveying belt 51, and the input end of the second guide 52 extends to the leading end of the cull limiting rod 501. The output end of the second guide 52 leaves a gap with the output end of the discharge conveying belt 51. The second guide 52 comprises two second guide plates arranged in parallel, and the two second guide plates form a conveying gap for the upright arrayed ampoules to pass through. The subsequent qualified upright arrayed ampoules enter the conveying gap between the two second guide plates through the cull limiting rod 501 under the conveying of the discharge conveying belt 51, and then automatically swing downward to transition to the horizontal state after being conveyed out of the two second guide plates.

[0090] With reference to Figure 8 and Figure 10The output end of the discharge conveying belt 51 is connected with a rear-end packaging device used in cooperation with the BFS product automatic lamp inspection machine. The output end of the discharge conveying belt 51 is provided with a transition plate 8. The transition plate 8 extends to the conveying plane of the discharge conveying belt 51 and is arranged flush with the conveying plane of the discharge conveying belt 51. The transition plate 8 is arranged to facilitate the better output of the aligned ampoule bottles on the discharge conveying belt 51 from the output end of the discharge conveying belt 51.

[0091] The output end of the discharge conveying belt 51 is also provided with an auxiliary conveying belt 81. One end of the auxiliary conveying belt 81 extends above the transition plate 8. The auxiliary conveying belt 81 and the transition plate 8 form a conveying gap for clamping and conveying the aligned ampoule bottles. The auxiliary conveying belt 81 is arranged to facilitate the better output of the aligned ampoule bottles conveyed by the discharge conveying belt 51 to the transition plate 8 to the outside of the transition plate 8, thereby reducing the accumulation of the aligned ampoule bottles in the transition plate 8, which is a non-powered area, and causing the accumulation of materials at the output end of the discharge conveying belt 51.

[0092] The input end of the inverted conveying mechanism 2 and the input end of the first vertical conveying part are both provided with a defoaming part. The defoaming part is located on one side of the conveying path of the aligned ampoule bottles. The defoaming part includes a defoaming air cylinder 7. The defoaming air cylinder 7 is arranged towards the conveying path of the aligned ampoule bottles. The piston rod of the defoaming air cylinder 7 is coaxially connected with a defoaming rod 71. The defoaming air cylinder 7 is electrically connected with a control module.

[0093] When the aligned ampoule bottles are conveyed to the defoaming air cylinder 7, the control module controls the defoaming air cylinder 7 to drive the defoaming rod 71 to reciprocally strike the aligned ampoule bottles, so as to eliminate the air bubbles in the ampoule bottles and reduce the interference of the air bubbles on the subsequent control module in judging whether the ampoule bottles are qualified.

[0094] The implementation principle of the embodiment of the present application is that the aligned ampoule bottles in the inverted state are transmitted into the BFS lamp inspection machine through the feeding conveying structure, and then conveyed through the inverted conveying mechanism 2, the inclined conveying mechanism 3 and the vertical conveying mechanism 4 to convey the aligned ampoule bottles, and gradually transition the aligned ampoule bottles from the inverted state to the inclined state and the vertical state. Preferably, the aligned ampoule bottles are transmitted out through the discharge conveying mechanism 5. During the conveying, the cameras 61 at each position of the inverted conveying mechanism 2, the inclined conveying mechanism 3 and the vertical conveying mechanism 4 capture the images of the aligned ampoule bottles in the corresponding postures and feed back to the control module. The control module judges whether the aligned ampoule bottles are qualified according to the feedback images. When the unqualified aligned ampoule bottles are output to the blowout air knife 502 through the discharge conveying belt 51, the blowout air knife 502 blows them out of the discharge conveying belt 51, thereby realizing the automatic rejection of the unqualified aligned ampoule bottles.

[0095] The inverted conveying mechanism 2, the inclined conveying mechanism 3 and the upright conveying mechanism 4 are used to convey the aligned ampoules from the inverted state to the inclined state and the upright state gradually, so that the camera 61 at the image acquisition assembly 6 can obtain clearer and more complete internal and external conditions of the aligned ampoules, and then the subsequent control module can better judge whether the aligned ampoules are qualified.

[0096] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
