Description

Technical Field

[0001] This utility model relates to the field of label detection technology, and in particular to a label-free detection mechanism for plastic bottles. Background Technology

[0002] With economic development, labels are widely used on commodities, driving the rapid development of the label printing industry. During the production and processing of products, labels need to be affixed, and these labels must also include production batch numbers. In the label processing technology, the position of the labels needs to be checked to identify products with incorrectly or crookedly placed labels.

[0003] Existing detection methods generally rely on manual visual inspection for selection. Obviously, manual inspection is not only inefficient, but also prone to visual fatigue after long hours of work, leading to missed or incorrect detections and thus low detection accuracy.

[0004] Chinese utility model patent (authorization announcement number: CN201689317U, name: label detection system) effectively reduces production costs, improves product quality and production speed, and prevents bottles with missing labels from entering the market and affecting the company's image. This system can not only detect the presence of labels on bottles on a high-speed production line, but also accurately reject bottles with missing labels and effectively prevent bottle tipping. Its structure includes a detection unit, a rejection unit, and a rejection confirmation unit arranged sequentially along the bottle flow direction on the production line chain. A control device is also provided on the side of the production line chain. The detection unit, rejection unit, and rejection confirmation unit are all connected to the controller in the control device. The production line chain corresponding to the rejection unit is also connected to the bottle recycling chain. However, if the bottles on the production line rotate unexpectedly, the detection unit may fail to scan the label, resulting in false detections. Utility Model Content

[0005] The purpose of this invention is to provide a label-free detection mechanism for plastic bottles to overcome the shortcomings of existing technologies.

[0006] The purpose of this utility model is achieved through the following technical solution: a label-free detection mechanism for plastic bottles, including a belt conveyor, a worktable fixed on the frame of the belt conveyor, the table surface of the worktable spanning the belt of the belt conveyor, a turntable installed on the worktable, the turntable being driven by a reduction motor fixed on the worktable, a baffle and a bracket also fixed on the worktable, the baffle being located between the turntable and the bracket, a barcode scanning slot being provided on the baffle, and a barcode reader being installed on the bracket, the barcode reader scanning the label of the plastic bottle through the barcode scanning slot.

[0007] Preferably, there are three scanning slots distributed vertically, and there are three barcode readers, each corresponding to one of the scanning slots.

[0008] Preferably, the bracket includes a column, a round rod, and an A-clamping member. The round rod is fixed to the column by the A-clamping member, and the barcode reader is fixed to the round rod by a clamp.

[0009] Preferably, a limiting ring is fixed on the turntable, the limiting ring is coaxial with the turntable, and an elastic sheet is fixed on the inner wall of the limiting ring. The elastic sheet is a plurality of sheets and is evenly distributed along the circumference of the limiting ring. The plastic bottle is clamped in the limiting ring by the elastic sheet.

[0010] Preferably, the A clamping member is block-shaped, and has an A through hole and a B through hole. The A through hole is opened along the Y-axis direction, and the B through hole is opened along the X-axis direction. The A clamping member also has an A notch and a B notch. The A notch communicates with the A through hole, and the B notch communicates with the B through hole. The A clamping member is also screwed with an A bolt and a B bolt. The A bolt is used to narrow the A notch, and the B bolt is used to narrow the B notch. The column is inserted into the A through hole, and the round rod is inserted into the B through hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Plastic bottles are placed on a turntable and rotated. The labels are read by a barcode reader. If the barcode reader does not read or write the label, it means that the bottle is missing a label and can be removed. This prevents false detections, reduces the labor intensity of workers, and avoids visual fatigue. Attached Figure Description

[0023] like Figure 1 and2 As shown, a label-free plastic bottle detection mechanism includes a belt conveyor 1, a workbench 2 fixed on the frame of the belt conveyor 1, and a turntable 3 mounted on the workbench 2. The turntable 3 is driven by a geared motor 4 fixed on the workbench 2. A baffle 5 and a support are also fixed on the workbench 2. The baffle 5 is located between the turntable 3 and the support. A barcode scanning slot 6 is provided on the baffle 5. A barcode reader 7 is mounted on the support. The barcode reader 7 scans the label of the plastic bottle through the barcode scanning slot 6. The plastic bottle is placed on the turntable 3 and rotated. The label is read by the barcode reader 7. If the barcode reader 7 does not read the label, it means that the bottle is missing a label and can be rejected. This prevents false detections, reduces the labor intensity of workers, and avoids visual fatigue.

[0024] In this embodiment, as Figure 1 and 2 As shown, there are three barcode scanning gaps 6 distributed vertically, and three barcode readers 7 corresponding to each of the barcode scanning gaps 6. If all three barcode readers 7 read and write the label, it means the label is correctly affixed. If only the top or bottom barcode reader 7 reads and writes the label, it means the label is completely misaligned and needs to be reattached. If only the top and middle or middle and bottom barcode readers 7 read and write the label, it means the label is affixed too high or too low, and the labeling station needs to be checked in time to find the cause.

[0025] In this embodiment, as Figure 2 and 3 As shown, the bracket includes a column 8, a round rod 9, and a clamping component A. The round rod 9 is fixed to the column 8 by the clamping component A. The barcode reader 7 is fixed to the round rod 9 by a clamp 10. The clamping component A is block-shaped and has an A through hole and a B through hole. The A through hole is opened along the Y-axis direction, and the B through hole is opened along the X-axis direction. The clamping component A also has an A notch 12 and a B notch 13. The A notch 12 communicates with the A through hole, and the B notch 13 communicates with the B through hole. The clamping component A also has an A bolt 14 and a B bolt 15 screwed on it. The A bolt 14 is used to narrow the A notch 12, and the B bolt 15 is used to narrow the B notch 13. The column 8 is inserted into the A through hole, and the round rod 9 is inserted into the B through hole, clamping firmly to prevent the round rod 9 from shifting due to slight impacts. If the position of the round rod 9 needs to be readjusted, it will affect the barcode reader 7's scanning of the label on the plastic bottle.

[0026] In this embodiment, as Figure 1 and 2 As shown, a limiting ring is fixed on the turntable 3. The limiting ring is coaxial with the turntable 3. An elastic sheet 11 is fixed on the inner wall of the limiting ring. There are several elastic sheets 11 and they are evenly distributed along the circumference of the limiting ring. The plastic bottle is clamped in the limiting ring by the elastic sheets 11 to avoid relative rotation between the plastic bottle and the turntable 3, which would affect the detection of the label.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
