Abstract
Description
Technical Field
[0001] This invention relates to the field of circular can transport technology, and in particular to a circular can flipping and coding association system. Background Technology
[0002] In modern fast-moving consumer goods, food and beverage, and chemical manufacturing industries, automated production lines are increasingly demanding traceability management throughout the product lifecycle. Particularly for round canned packaging containers (such as milk powder cans, aerosol cans, and canned goods), digitally encoding information (including QR codes, 1D barcodes, and clear numerical codes) onto the top and bottom lids, and accurately linking the information between the can and lid, is a crucial step in building intelligent factory information systems and meeting market regulatory compliance requirements.
[0003] However, in existing traditional production processes, the loading of digital information onto such curved or uneven packaging generally relies on manual operation. Specifically, workers must manually affix pre-printed labels to designated locations on the cans one by one beside the production line. This manual information loading method has significant inherent drawbacks: First, from the perspective of production cycle time, the speed of manual pasting is limited by the skill level and physical limits of the operators, making it difficult to match the high-speed operation of automated filling and packaging equipment. This can easily cause an imbalance in the production line cycle time, creating a production bottleneck and severely restricting the improvement of overall production efficiency.
[0004] Secondly, because the surface of a circular can is usually curved, and manual operation inevitably involves randomness, labels are prone to misalignment, tilting, or poor adhesion during application. This uncontrollability of physical position means that automated visual acquisition equipment (such as industrial cameras and barcode scanners) installed in subsequent processes cannot accurately capture digital information at standard workstations. Once reading fails, the system often determines the product as defective and triggers a rejection mechanism.
[0005] Furthermore, a large number of qualified products that were mistakenly rejected require additional manual intervention for re-inspection and relabeling. This not only increases the frequency of manual intervention on the production site, but also leads to chaos in material flow and a surge in rework costs. Summary of the Invention

[0022] See Figure 1 As can be seen, this embodiment provides a schematic diagram of a circular can body flipping up and down and a coding association system.
[0023] The system includes: The transmission line 100 is configured to transmit a vertically placed circular can along a preset direction.
[0024] Specifically, in this embodiment, the transmission line 100 includes a first transmission line 110, on which a conveyor belt moving in a preset direction is provided; and a second transmission line 120, on which a conveyor belt moving in a preset direction is provided.
[0025] A conveyor belt is installed on the first transmission line 110, which transports the circular cans towards the second transmission line 120. The circular cans are inverted, with their bottoms facing upwards. During this section, QR code information is loaded onto the bottom cover of the circular can, i.e., a QR code on the can bottom. Loading methods include: pasting QR code labels, laser engraving, or inkjet printing.
[0026] The system also includes: A flipping component 200 is disposed on the transmission line 100; the flipping component 200 is configured to flip the circular can being transmitted on the transmission line 100 by 180° in a preset clockwise direction; a bottom QR code is provided on one side of the circular can, and the bottom QR code is located on the side of the circular can away from the transmission line 100 before the circular can is flipped.
[0027] Specifically, in this embodiment, the rotating component 200 completes the 180° rotation of the circular can, thereby realizing the subsequent coding association of the circular can.
[0028] The flipping component 200 is located in the middle of the second transmission line body 120.
[0029] The second transmission line 120 transports the circular tank to the right. The front of this section transports an inverted circular tank.
[0030] The flipping component 200 includes: A flipping component 210 is disposed on the second transmission line 120, and the edge of the flipping component 210 has a preset distance from the second transmission line 120 during the flipping process; the flipping component 210 is configured to flip the circular can being transported on the second transmission line 120 by 180° in a preset clockwise direction. A rotary motor 220 is disposed on the side of the second transmission line body 120 and is connected to the flipping member 210; the rotary motor 220 is configured to drive the flipping member 210 to rotate 180° in the preset clockwise direction.
[0031] Specifically, in this embodiment, the rotary motor 220 provides the flipping force to the flipping component 210, and the flipping component 210 flips the circular can by 180°.
[0032] Furthermore, in some embodiments, the flipping assembly 200 further includes a motor support plate 230, which is disposed on the side of the second transmission line body 120, and the bottom of the rotary motor 220 is detachably connected to the motor support plate 230.

[0033] Specifically, in this embodiment, since the same production line does not only transport circular cans of the same size, and different circular cans must be adapted to different sizes and heights of the flipping component 210, a motor support plate 230 is also provided on the side of the second transmission line 120. The relative height between the motor support plate 230 and the second transmission line 120 can be adjusted according to actual needs. This is achieved by sliding the motor support plate 230 and the second transmission line 120 together and setting a fixing structure between them, thereby achieving height adjustment. The connection between the flipping component 210 and the rotary motor 220 is set to be detachable. When adapting to circular cans of different sizes, the flipping component 210 of different sizes is replaced, thereby enabling the flipping component 210 to flip circular cans of different sizes. Furthermore, the edge of the flipping component 210 will not scratch the second transmission line 120 during the flipping process.
[0034] The flipping component 210 has a structure with a hyperboloidal groove, the two curved grooves of which are adapted to the dimensions of the circular can; the dimensions of the circular can and the flipping component 210 are defined as follows: 2R<H≤3.2R h = 2 / 3H; Where R is the radius of the circular can and the curved groove of the flipping component 210, H is the height of the circular can, and h is the height of the flipping component 210.

[0037] The system also includes: A first photoelectric switch 500 is disposed on one side of the second transmission line 120. The first photoelectric switch 500 is located on the side of the flipping component 200 close to the first transmission line 110. The first photoelectric switch 500 is configured to detect whether the circular can has reached a first specified position, thereby driving the QR code reader 300 to read the data information of the QR code on the bottom of the can.
[0038] Specifically, in this embodiment, the first photoelectric switch 500 obtains information about the circular can reaching a first designated position, and uses this information to drive the QR code reader 300 to read the data information of the QR code on the bottom of the can.
[0039] The system also includes: A laser marking machine 400 is disposed above the transmission line 100; the laser marking machine 400 is configured to laser-etch a QR code on the top of the can, corresponding to the data information of the QR code on the bottom of the can, onto the other circular surface of the flipped circular can.
[0040] Specifically, in this embodiment, a laser marking machine 400 is also provided above the second transmission line 120, and the laser marking machine 400 is located on the side of the flipping component 200 away from the first transmission line 110. The laser marking machine 400 laser-etches a QR code on the top of the can onto the other side of the flipped circular can, thereby completing the coding association of the circular can.
[0041] The system also includes: A second photoelectric switch 600 is disposed on one side of the second transmission line 120 and located on the side of the flipping assembly 200 away from the first transmission line 110. The second photoelectric switch 600 is configured to detect whether the circular can has reached a second designated position, thereby driving the laser marking machine 400 to laser-engrave the QR code on the top of the can on the other side of the circular surface of the flipped circular can.
[0042] Specifically, in this embodiment, the second photoelectric switch 600 obtains relevant information about the circular can reaching the second designated position, thereby driving the laser marking machine 400 to laser-burn the QR code on the top of the can on the other side of the circular surface of the flipped circular can.
[0043] Furthermore, in some embodiments, the system further includes an industrial control computer 700, which is configured to: The first position arrival information of the first photoelectric switch 500 is obtained and a first driving instruction is generated; the first driving instruction is used to drive the QR code reader 300 to read the data information of the QR code on the bottom of the can. The second position arrival information of the second photoelectric switch 600 is obtained, and a second driving command is generated based on the data information of the QR code on the bottom of the can and the second position arrival information; the second driving command is used to drive the laser marking machine 400 to laser-burn the QR code on the top of the can on the other side of the circular surface of the flipped circular can.
[0044] Specifically, in this embodiment, the industrial control computer 700 generates corresponding control commands based on the relevant location information sent by the first photoelectric switch 500 and the second photoelectric switch 600, thereby realizing automated code reading, association, and code assignment.
[0045] It should be noted that the rotation control of the rotary motor 220 can also be controlled by the industrial control computer 700. The industrial control computer 700 can calculate the rotation timing based on the first position arrival information sent by the first photoelectric switch 500, thereby realizing the automation of the rotation of the circular tank.
[0046] Furthermore, in some embodiments, the system further includes: A capping machine is disposed above the second transmission line 120 and is located on the side of the laser marking machine 400 away from the flipping assembly 200; the capping machine is configured to seal the top of the can onto the flipped circular can.
[0047] Specifically, in this embodiment, the industrial control computer 700 can also be configured to control the capping machine to seal the top of the can onto the top of the circular can, while completely covering the QR code data information on the top of the can to ensure the data security of the QR code on the top of the can.
[0048] This embodiment has the following advantages: This embodiment of a circular can-flipping and coding association system perfectly realizes the automatic 180-degree vertical flipping of circular cans on the production line. While the QR code reader reads the QR code information on the bottom cover of the circular can, after the can is vertically flipped by the flipping mechanism, a corresponding QR code is burned onto the top cover of the circular can by a laser coding machine, thus achieving the corresponding association between the QR code information on the top and bottom covers of the circular can. After the top cover of the circular can is sealed in the next stage, only the QR code information on the bottom cover is exposed during the product's circulation. Even if the bottom cover QR code is damaged during circulation, the sealed top cover QR code information can still be used for product authenticity verification, logistics tracking, and quality traceability at each stage of circulation.
