Description

Technical Field

[0001] This utility model relates to the field of industrial testing equipment technology, and in particular to an online testing device for the integrity of labels on double-sided labeled oil bottles. Background Technology

[0002] On edible oil bottle bottling lines, the final step is usually affixing labels to the bottles. Currently, label quality inspection relies heavily on manual visual inspection or fixed industrial cameras. Manual inspection is inefficient, prone to fatigue, and inconsistent in standards; while fixed camera inspection solutions typically require multiple cameras to be placed on both sides and above and below the conveyor line to inspect the bottle's perimeter, resulting in high costs. In the packaging production of liquids such as edible oil, labels are usually affixed to the front and back side walls of the bottles. Whether labels are missing is a crucial indicator of product quality. Currently, the quality inspection of bottle labeling relies entirely on manual visual inspection. This method is labor-intensive, inefficient, and prone to missed or false inspections due to fatigue, failing to meet the online inspection requirements of modern high-speed production lines. Utility Model Content

[0003] This utility model provides an online detection device for the integrity of double-sided labeled oil bottles. Its purpose is to solve the problems of traditional bottle label quality detection relying on manual visual inspection, which is labor-intensive, inefficient, and prone to missed or false detections due to fatigue.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An online inspection device for the integrity of double-sided labeled oil bottles includes a frame and a conveyor longitudinally mounted on the frame. A horizontal positioning plate is mounted on one side of the frame in the middle of the conveyor. A positioning sleeve that can slide laterally is fitted onto the positioning plate. A column is vertically fixed to the positioning sleeve. A clamping positioning block that can be adjusted in height is fitted onto the side wall of the column. A mounting plate is mounted on the clamping positioning block. A barcode reader for detecting the barcode on the side label of the oil bottle is mounted on the mounting plate. A horizontal support plate is mounted on the conveyor to the side rear of the barcode reader. A telescopic cylinder is laterally mounted on the support plate. The telescopic end of the telescopic cylinder faces the conveyor and is equipped with a push plate. A platform for receiving oil bottles pushed away is mounted on the side of the conveyor corresponding to the push plate. A plane mirror fixed by a support frame is mounted on the rear end of the conveyor. The mirror surface of the plane mirror faces the oil bottle on the conveyor to reflect the image on the back of the oil bottle. The barcode reader and the telescopic cylinder are electrically connected to a control system.

[0005] Furthermore, the front end of the conveyor is equipped with two centering plates for guiding the oil bottles. Each centering plate is fixedly connected to the frame via a first bracket. This ensures that the oil bottles are centered on the conveyor when entering the inspection station, improving the success rate of barcode reader scanning and back-side image capture.

[0006] Furthermore, a threaded hole is provided on the side wall of the positioning sleeve, and a positioning screw for fastening the positioning sleeve to the positioning plate is screwed into the threaded hole. This allows the lateral position of the barcode reader to be easily adjusted and locked according to different bottle shapes.

[0007] Furthermore, the system also includes through-beam sensors for detecting whether the oil bottle has reached the scanning station. These sensors are positioned on both sides of the conveyor in front of the barcode reader. The through-beam sensors trigger the barcode reader to scan, ensuring the timeliness and accuracy of the detection action.

[0008] Furthermore, the through-beam sensor includes a laser emitting sensor and a laser receiving sensor, which are respectively placed on both sides of the conveyor and fixedly connected to sensor supports provided on the side of the frame.

[0009] Furthermore, an alarm is installed on the positioning plate. When the barcode reader fails to scan or detects abnormal label information, the control system can trigger the alarm to issue an audible and visual alarm, prompting the operator to handle the situation.

[0010] Furthermore, the barcode reader, through-beam sensor, telescopic cylinder, and alarm are all electrically connected to the control system. The entire detection, judgment, execution, and alarm process is centrally controlled by the control system, achieving high detection efficiency and reliability.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves the detection and sorting of double-sided labeled oil bottles through the coordinated work of a barcode reader, a plane mirror, a sensor, and a telescopic cylinder, which greatly improves production efficiency and detection accuracy, and reduces labor costs and labor intensity.

[0012] 2. The barcode reader of this utility model achieves three-dimensional adjustment in the horizontal, vertical and height directions through the positioning slide sleeve, column and mounting plate, which can quickly adapt to oil bottles of different specifications and shapes, and the equipment has high versatility and flexibility.

[0013] 3. This utility model ensures the centering of the bottle body through the centering plate and the precise positioning and triggering of the through-beam sensor, thus guaranteeing the repeatability of the detection station and the stability of the detection process.

[0017] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0018] Example 1: like Figures 1 to 5 As shown, an online inspection device for the integrity of labels on double-sided labeled oil bottles mainly includes a frame 1, a conveyor 2, an inspection mechanism, a sorting mechanism, and a reflection mechanism.

[0019] In this embodiment, the conveyor 2 is longitudinally mounted on the frame 1 for continuously conveying oil bottles to be tested. A pair of V-shaped centering plates 14 are installed on both sides of its front end. The centering plates 14 are fixed to the side of the conveyor 2 by the first bracket 15 to guide the bottles to the center line of the conveyor.

[0020] In this embodiment, the detection mechanism includes a barcode reader 7 and its adjustment bracket. The adjustment bracket consists of a positioning plate 3, a positioning sliding sleeve 4, a column 5, and a mounting plate 6. Please refer to [link to relevant documentation]. Figure 1Positioning plate 3 is horizontally fixed to frame 1. Positioning sleeve 4 is fitted onto positioning plate 3 and can slide laterally. Threaded holes are provided on the side wall of positioning sleeve 4, and positioning screws 16 for fastening positioning sleeve 4 onto positioning plate 3 are screwed into the threaded holes. Column 5 is vertically fixed onto positioning sleeve 4. A clamping positioning block 51 is fitted onto column 5 and secured with bolts. Loosening the bolts allows clamping positioning block 51 to move up and down along column 5 to adjust its height. Mounting plate 6, an L-shaped plate, is fixedly mounted on the side of clamping positioning block 51. A barcode reader 7 is fixedly mounted on the horizontal plate of mounting plate 6. Clamping positioning block 51 can slide up and down and its height is fixed with screws. Barcode reader 7 is a commercially available product, mounted on mounting plate 6, with its lens facing the barcode label on the back of the oil bottle on the conveyor. On both sides of the conveyor in front of the barcode reader 7, through-beam sensors 17 (including laser emitter 171 and laser receiver 172) are installed via sensor supports 18. These sensors are used to detect whether the oil bottle has reached the predetermined station and trigger scanning. The laser emitter 171 and laser receiver 172 are both commercially available products used to detect the position of the oil bottle.

[0021] In this embodiment, the reflection mechanism includes a plane mirror 12 mounted on the rear side of the conveyor 2 via a support frame 13. The plane mirror 12 is fixed to the side of the conveyor 2 via the support frame 13. Please refer to [link to relevant documentation]. Figure 1 , 3 4. The mirror surface of the plane mirror 12 is tilted towards the conveyor belt so that it can reflect the image of the label on the back of the oil bottle into the operator's field of vision, making it easier for the inspector to check both sides.

[0022] In this embodiment, the sorting mechanism includes a telescopic cylinder 9, a pusher plate 10, and a shelf 11. Please refer to [link / reference]. Figure 5 The telescopic cylinder 9 (which can be a pneumatic cylinder or an electric push rod) is mounted on one side of the conveyor 2 via a horizontally positioned support plate 8, located behind the barcode reader 7 station. A push plate 10 is mounted on the piston rod end of the telescopic cylinder 9. A storage platform 11 is positioned on the other side of the conveyor 2, directly opposite the push plate 10, to receive defective products (missing labels) pushed away by the telescopic cylinder 9.

[0023] In this embodiment, an alarm 19 is provided on the positioning plate 3. The support of the alarm 19 is fixedly installed on the positioning plate 3. When a defective product is found, it is used to issue a fault or abnormal alarm.

[0024] In this embodiment, the barcode reader 7, the through-beam sensor 17, the telescopic cylinder 9, and the alarm 19 are all electrically connected to the control system.

[0025] Working principle: Please see Figures 1-5Oil bottles are conveyed by the conveyor 2, and continue to move forward after being aligned by the centering plate 14. When an oil bottle passes through the opposite-beam sensor 17, a sensor signal is triggered and sent to the control system. The control system then instructs the barcode reader 7 to operate. The barcode reader 7 first directly collects the image of the barcode label on the back of the oil bottle, performs decoding and integrity analysis, then an operator indirectly collects the image of the back label of the oil bottle through reflection from the plane mirror 12, and determines whether the label is complete.

[0026] Wherein, the control system judges the analysis result of the barcode image on the back side: If both labels are complete and correct, the oil bottle is determined as a qualified product. The telescopic cylinder 9 does not act, and the oil bottle continues to be conveyed to the next process.

[0027] If the label is missing or unrecognizable, the oil bottle is determined as an unqualified product. When the unqualified product moves to the front of the push plate 10 along with the conveyor belt, the control system instructs the telescopic cylinder 9 to act, or an operator manually operates the remote controller to control the telescopic cylinder 9 to move, which pushes the push plate 10 to push the unqualified oil bottle away from the conveyor belt, so that the unqualified oil bottle falls onto the adjacent placement table 11 for centralized treatment. Meanwhile, the control system triggers the alarm 19 to alarm and prompt the operator.

[0028] Those skilled in the art will easily think of other implementation solutions of the present utility model after considering the specification and practicing the present utility model disclosed herein. The present utility model is intended to cover any variation, use or adaptive change of the present utility model, and such variation, use or adaptive change follow the general principle of the present utility model and include common general knowledge or conventional technical means in the technical field not disclosed by the present utility model.

The embodiments of the present utility model described above do not limit the protection scope of the present utility model.
