Abstract
Description
Technical Field
[0001] This disclosure relates to the field of label detection technology, and in particular to a label dual-recognition detection device and a high-speed labeling machine. Background Technology
[0002] In the pharmaceutical production process, it is usually necessary to label the product bottles. Early label detection generally used image recognition technology. However, when the line speed of the labeling machine is too high, such as when the line speed of the high-speed labeling machine exceeds 1000 labels / minute, there is a problem of missing labels.
[0003] Of course, there are also some methods on the market that use photoelectric detection, such as the automatic label-missing detection method for labeling machines disclosed in Chinese patent document CN 111746890A. This method specifically combines a first photoelectric switch, a second photoelectric switch, a laser sensor, and a control program to detect bottle labels. However, during detection, it requires two data acquisitions via the first and second photoelectric switches. This results in the control program having to process the photoelectric acquisition information twice, leading to a relatively slow overall processing speed. Therefore, it cannot adapt to the rapid detection of high-speed labeling machines, meaning the probability of label misses remains relatively high. Utility Model Content
[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a dual-identification detection device for labels with simple structure, fast signal processing speed, and low probability of label miss detection, especially suitable for rapid detection in high-speed labeling machines and high-speed labeling machines.
[0005] The purpose of this disclosure is achieved through the following technical solution:
[0006] A label dual-recognition detection device includes a conveying component, a labeling component, an image detection component, a photoelectric detection component, and a processing module. The conveying component is mounted on the frame of a high-speed labeling machine, and the labeling component is mounted on the conveying component.
[0007] The image detection component and the photoelectric detection component are arranged sequentially along the conveying direction of the conveying component; the camera of the image detection component is located near the exit end of the labeling component;
[0008] The photoelectric detection component includes an infrared transmitter and an infrared receiver. The infrared transmitter is located on one side of the conveying component and is adjacent to the camera. The infrared receiver is disposed on the conveying component on the opposite side of the infrared transmitter. The external receiver, the infrared transmitter, and the image detection component are all electrically connected to the processing module.
[0009] In one embodiment, the mounting bracket of the infrared receiver is threadedly connected to the delivery assembly.
[0010] In one embodiment, the receiving area of the infrared receiver is larger than the light reflecting area of the infrared emitter.
[0011] In one embodiment, the tag dual recognition detection device further includes a rejection collection component, which includes an air tube and a collection basket. The collection basket is disposed on one side of the conveying component between the camera and the infrared emitter, and the collection basket is connected to the conveying area of the conveying component. The air tube is disposed opposite to the collection basket and is connected to the conveying area of the conveying component.
[0012] In one embodiment, the conveying assembly has a conveying area and an outlet connected together, and an inclined collection cavity is formed in the collection basket, the inclined collection cavity being connected to the conveying area through the outlet.
[0013] In one embodiment, the infrared receiver is located inside the outlet.
[0014] In one embodiment, the trachea is positioned adjacent to the infrared emitter.
[0015] In one embodiment, the collection basket includes a cover and a collection frame. The collection frame is connected to one side of the conveying assembly, and the cover is rotatably disposed inside the collection frame. An inclined surface is formed inside the collection frame, and the cover and the collection frame together form the inclined collection cavity.
[0016] In one embodiment, the cover plate has a plurality of vent holes.
[0017] A high-speed labeling machine includes the label dual recognition and detection device described in any of the above embodiments.
[0018] Compared with the prior art, this disclosure has at least the following advantages:
[0019] Because the image detection component and the photoelectric detection component are arranged sequentially along the conveying direction of the conveying component; the camera of the image detection component is located near the exit end of the labeling component, enabling preliminary detection of the bottle label by the image detection component; because the infrared emitter is located on one side of the conveying component and near the camera; the photoelectric detection component is located downstream of the image detection component, and the infrared receiver is positioned opposite the infrared emitter. In use, the infrared emitter emits infrared light towards the bottle, the label on the bottle reflects the infrared light, and the infrared receiver collects the reflected infrared light signal. The processing module processes and judges the collected infrared light signal. If the intensity of the collected infrared light signal exceeds a preset threshold, it is determined that the bottle has a label; otherwise, it is determined to be abnormal, and the machine is stopped immediately. In this way, only one acquisition is needed to achieve secondary confirmation of the bottle label, that is, to achieve dual label recognition. This not only simplifies the structure of the photoelectric detection component, but also improves the signal processing speed of the processing module of the photoelectric detection component, so as to better adapt to the rapid detection of high-speed labeling machines, thereby effectively reducing the probability of label missed detection.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0029] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0030] Please see Figures 1 to 3A label dual-recognition detection device 10 according to one embodiment includes a conveying assembly 100, a labeling assembly 200, an image detection assembly 300, a photoelectric detection assembly 400, and a processing module (not shown). The conveying assembly 100 is mounted on the frame of a high-speed labeling machine, and the labeling assembly 200 is mounted on the conveying assembly 100. The image detection assembly 300 and the photoelectric detection assembly 400 are arranged sequentially along the conveying direction of the conveying assembly 100. The camera 310 of the image detection assembly 300 is located near the outlet 120 of the labeling assembly 200. The photoelectric detection assembly 400 includes an infrared emitter 410 and an infrared receiver 420. The infrared emitter 410 is located on one side of the conveying assembly 100 and is located near the camera 310. The infrared receiver 420 is mounted on the conveying assembly 100 on the opposite side of the infrared emitter 410. The external receiver, the infrared emitter 410, and the image detection assembly 300 are all electrically connected to the processing module.
[0031] It is understood that, since the image detection component 300 and the photoelectric detection component 400 are arranged sequentially along the conveying direction of the conveying component 100; the camera 310 of the image detection component 300 is located near the outlet 120 of the labeling component 200, enabling preliminary detection of the bottle label by the image detection component 300; since the infrared emitter 410 is located on one side of the conveying component 100 and near the camera 310; the photoelectric detection component 400 is located downstream of the image detection component 300, and the infrared receiver 420 is arranged opposite to the infrared emitter 410, in use, the infrared emitter 410 will emit light towards the bottle. Infrared light is reflected by the label on the bottle, and the infrared receiver 420 collects the reflected infrared light signal. The processing module processes and judges the collected infrared light signal. If the intensity of the collected infrared light signal exceeds a preset threshold, it is determined that the bottle has a label; otherwise, it is determined to be abnormal, and the machine is stopped immediately. In this way, only one collection is needed to realize the secondary confirmation of the bottle label, that is, to achieve dual label recognition. This not only simplifies the structure of the photoelectric detection component 400, but also improves the signal processing speed of the processing module of the photoelectric detection component 400, so as to better adapt to the rapid detection of high-speed labeling machines, thereby effectively reducing the probability of label missed detection.
[0032] In use, the medicine bottle is conveyed to the labeling component 200 via the conveying component 100. The labeling component 200 then affixes the label to the body of the medicine bottle. Next, the conveying component 100 delivers the bottle to the image detection component 300 at the outlet 120 of the labeling component 200. The camera 310 of the image detection component 300 takes a picture and recognizes the image information. The processing module judges and processes the image information. If an abnormality is found, the subsequent rejection collection component 500 will reject the defective product. Then, the conveying component 100 delivers the bottle to the photoelectric detection component 400 for secondary confirmation. If an abnormality is found, the high-speed labeling machine will immediately stop.
[0033] Please see Figure 1 In one embodiment, the labeling assembly 200 includes an inlet star wheel 210, a labeling star turntable 220, a labeling system 230, and an outlet star wheel 240. The inlet star wheel 210, labeling star turntable 220, labeling system 230, and outlet star wheel 240 are sequentially arranged on the conveying assembly 100. An image detection assembly 300 is disposed between the outlet star wheel 240 and the labeling system 230, and is located on one side of the outlet star wheel 240, such that the image detection assembly 300 is positioned... The front end of the bottle ejector wheel 240 is located at the rear end of the labeling system 230, enabling better detection of the freshly labeled bottle. The photoelectric detection component 400 is located on the other side of the bottle ejector wheel 240, at the rear end of the bottle ejector wheel 240, ensuring that the distance between the photoelectric detection component 400 and the image detection component 300 is set reasonably, thereby achieving rapid dual recognition detection of the bottle label, quickly isolating unqualified products, and reducing the number of unqualified products isolated.
[0034] It should be noted that the labeling component 200, image detection component 300, photoelectric detection component 400, and processing module are all prior art, and therefore will not be described in detail in this disclosure. It is worth mentioning that the image recognition principle of the image detection component 300, the light recognition principle of the photoelectric detection component 400, and the data processing principle of the processing module are not within the scope of protection of this disclosure; this disclosure only protects the connection relationship between the image detection component 300, the photoelectric detection component 400, and the processing module.
[0035] In one embodiment, the mounting bracket 411 of the infrared receiver 420 is threadedly connected to the conveying assembly 100, enabling the infrared receiver 420 and the conveying assembly 100 to be detachably connected, facilitating the user's disassembly and replacement of damaged infrared receiver 420. Furthermore, since the mounting bracket 411 has an adjustment groove with a locking element, the user can easily adjust the height of the conveying assembly 100 connected to the mounting bracket 411, thereby improving the adaptability of the photoelectric detection assembly 400 to labels of different sizes.
[0036] In one embodiment, the receiving area of the infrared receiver 420 is larger than the light reflecting area of the infrared emitter 410, so that the infrared receiver 420 can receive the light reflected from the bottle more comprehensively, thereby improving the accuracy of the acquisition.
[0037] Please see Figure 1 In one embodiment, the image detection component 300 includes a camera 310 and a light shield 320. The camera 310 is positioned at the front end of the bottle dispensing star wheel 240, with the camera lens of the camera 310 perpendicular to the bottle body. The light shield 320 is located above the camera 310 to achieve a light-shielding effect on the camera 310.
[0038] In one embodiment, the dual-label identification detection device 10 further includes a rejection collection component 500, which includes an air tube 510 and a collection basket 520. The collection basket 520 is disposed on one side of the conveying component 100 between the camera 310 and the infrared emitter 410, and is connected to the conveying area 110 of the conveying component 100. The air tube 510 is disposed opposite to the collection basket 520 and is connected to the conveying area 110 of the conveying component 100. When the air tube 510 is connected to an external device, the gas blown out by the air tube 510 can push the non-conforming products on the conveying component 100 into the collection basket 520, thereby realizing the rejection operation of non-conforming products.
[0039] In one embodiment, the conveying assembly 100 has a conveying area 110 and an outlet 120 that are connected to each other. An inclined collection cavity 5221 is formed in the collection basket 520. The inclined collection cavity 5221 is connected to the conveying area 110 through the outlet 120, which realizes the connection between the collection basket 520 and the conveying assembly 100. The added inclined collection cavity 5221 makes it easier for defective products to slowly roll to the bottom of the collection basket 520, thereby realizing the collection of defective products.
[0040] Please see Figure 2 In one embodiment, the infrared receiver 420 is located inside the outlet 120, and the collection basket 520 is also located inside the outlet 120, so that the defective products detected by the infrared receiver 420 can be located within the collection port of the inclined collection cavity 5221. That is, the image detection component 300 and the photoelectric detection component 400 can work together in a single rejection collection component 500, thereby simplifying the structure of the tag dual recognition detection device 10.
[0041] In one embodiment, the air tube 510 is positioned adjacent to the infrared emitter 410, allowing it to effectively push defective products into the collection basket 520, thus enabling the image detection component 300 and the photoelectric detection component 400 to share a single rejection collection component 500. Furthermore, the gas blown from the air tube 510 effectively removes dust from the infrared emitter 410 and the infrared receiver 420, thereby ensuring the detection accuracy of the photoelectric detection component 400.
[0042] Please see Figure 3 and Figure 4 In one embodiment, the collection basket 520 includes a cover plate 521 and a collection frame 522. The collection frame 522 is connected to one side of the conveying assembly 100, specifically at the outlet 120 of the conveying assembly 100, thus enabling communication between the collection basket 520 and the conveying assembly 100. The cover plate 521 is rotatably disposed within the collection frame 522, facilitating the user to open the cover plate 521 and remove defective products. An inclined surface is formed within the collection frame 522, and the cover plate 521 and the collection frame 522 together form the inclined collection cavity 5221, ensuring that the inclined collection cavity 5221 is formed within the collection basket 520 for easy collection of defective products. It is worth noting that the rotatable arrangement of the cover plate 521 within the collection frame 522 is prior art. Therefore, it will not be described in detail in this disclosure.
[0043] In one embodiment, the cover plate 521 is provided with a plurality of vent holes 5211, which can effectively prevent the defective products in the collection basket 520 from rolling and colliding and breaking due to excessive gas volume when the air pipe 510 blows air.
[0044] In one embodiment, a plurality of vent holes 5211 are evenly distributed.
[0045] This disclosure also provides a high-speed labeling machine, including the label dual recognition detection device 10 described in any of the above embodiments, to achieve dual recognition detection of labels.
[0046] Compared with the prior art, this disclosure has at least the following advantages:
[0047] Since the image detection component 300 and the photoelectric detection component 400 are arranged sequentially along the conveying direction of the conveying component 100; the camera 310 of the image detection component 300 is located near the outlet 120 of the labeling component 200, enabling preliminary detection of the bottle label by the image detection component 300; since the infrared emitter 410 is located on one side of the conveying component 100 and near the camera 310; the photoelectric detection component 400 is located downstream of the image detection component 300, and the infrared receiver 420 is arranged opposite to the infrared emitter 410. In use, the infrared emitter 410 emits infrared light towards the bottle. The label on the bottle reflects infrared light, and the infrared receiver 420 collects the reflected infrared light signal. The processing module processes and judges the collected infrared light signal. If the intensity of the collected infrared light signal exceeds a preset threshold, it is determined that the bottle has a label; otherwise, it is determined to be abnormal, and the machine is stopped immediately. In this way, only one collection is needed to realize the secondary confirmation of the bottle label, that is, to achieve dual label recognition. This not only simplifies the structure of the photoelectric detection component 400, but also improves the signal processing speed of the processing module of the photoelectric detection component 400, so as to better adapt to the rapid detection of high-speed labeling machines, thereby effectively reducing the probability of label missed detection.
[0048] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
