[0029] The first robot 2 is used to grab the positioned packaging box on the positioning conveyor line 1 and place it on the hot stamping machine 3 for hot stamping;

[0030] The second robot 4 is used to grab the packaging box printed by the hot stamping machine 3, and rotate the packaging box and place it in the transfer machine 5 for transfer printing;

[0031] The third robot 6 is used to grab the packaging boxes after transfer, place the packaging boxes that do not need to be turned over on the unloading conveyor line 8, and place the packaging boxes that need to be turned over on the turning device 7; the turning device 7 is used to turn the packaging boxes over and place them on the unloading conveyor line 8.

[0032] like Figure 2 As shown, the positioning conveyor line 1 includes a bracket, a variable frequency conveying motor 101, a positioning belt line 102 and a guide roller 103;

[0033] The positioning belt line 102 and the variable frequency conveying motor 101 are both installed on the bracket. The variable frequency conveying motor 101 drives the positioning belt line 102 to rotate and convey the packaging box. The guide roller 103 is used to correct the direction of the packaging box on the positioning belt line 102, and the guide roller 103 is symmetrically installed on the bracket. The end of the positioning belt line 102 is installed with a photoelectric sensor 107 for detecting whether the packaging box is in place and an end limit plate 104 for limiting the packaging box. The end of the positioning belt line 102 is also installed with a positioning cylinder 106 that pushes the packaging box to make it close to the side positioning plate 105. The conveying and positioning of packaging boxes of various sizes and specifications are realized under the control of the control system.

[0034] The packaging box is manually placed on the positioning conveyor line 1. Under the control of the control system, the packaging box is conveyed forward via the positioning belt line 102, and the direction of the packaging box is corrected by the guide roller 103, and finally conveyed to the end close to the end limit plate 104. At this time, the photoelectric sensor 107 detects that the packaging box is in place, and the positioning cylinder 106 pushes the packaging box forward and close to the side positioning plate 105 to accurately position the packaging box.

[0035] like Figure 3 As shown, the turning device 7 includes a bracket, a lifting cylinder 701, a rotating cylinder 702, a clamping cylinder 703 and a discharge plate 704;

[0036] A lifting cylinder 701 is installed on one side of the bracket, and a rotating cylinder 702 is installed on a vertical guide rail 705 on the other side of the bracket. The lifting cylinder 701 drives the rotating cylinder 702 to slide up and down along the guide rail 705. A discharge plate 704 for receiving materials and a clamping cylinder 703 for fixing the packaging box on the discharge plate 704 are fixed on the rotating panel of the rotating cylinder 702.

[0037] Buffers 706 are provided at the top maximum displacement position and the bottom maximum displacement position of the guide rail 705 to buffer the rotating cylinder 702 .

[0038] When the workstation is running, the lifting cylinder 701 of the flipping device 7 rises to the top, the clamping cylinder 703 opens, and the rotating cylinder 702 rotates the material discharge plate 704 to the material receiving position. The robot grabs the finished packaging box and places it on the material discharge plate 704. Under the control of the control system, the clamping cylinder 703 clamps the packaging box, and the rotating cylinder 702 flips it again, and the lifting cylinder 701 descends to place the flipped packaging box on the unloading conveyor line 8.

[0039] like Figure 4 As shown, the unloading conveyor line 8 includes a bracket, an unloading belt line 801 and an unloading motor 802. The unloading motor 802 installed on the bracket drives the unloading belt line 801 to rotate. A receiving position of the unloading conveyor line 8 is provided with an in-place detection sensor 803 for detecting whether the packaging box is in place. Under the control of the control system, the unloading conveyor line 8 rotates, and the unloading motor 802 drives the unloading belt line 801 to transport the packaging box through the gear, chain and transmission shaft.

[0040] like Figure 5 As shown, the first robot 2, the second robot 4 and the third robot 6 are all six-axis MINI robots, which grab materials through multifunctional grippers. The structure and convenient programming of the six-axis robot can meet the requirements of grabbing, loading and unloading of packaging boxes of various sizes.

[0041] The workstation is controlled by a PLC controller. A safety fence is also installed on the workstation for protection. The packaging boxes come in a variety of sizes and specifications. The packaging box hot stamping / transfer robot workstation is controlled by a PLC program, and all sizes of packaging boxes can be automatically hot stamped / transferred.

[0042] Working process,

[0043] 1. Manually place the liquor packaging boxes on the positioning conveyor line 1 as required;

[0044] 2. The packaging box is transported to the end through the guide mechanisms on both sides of the positioning conveyor line 1 and is close to the end baffle;

[0045] 3. After the positioning mechanism at the end of the positioning belt line 102 detects the packaging box, it precisely positions the packaging box and sends the material picking information to the first robot 2;

[0046] 4. The first robot 2 grabs the precisely positioned packaging box and places it on the hot stamping machine 3 for hot stamping. After it is placed in place, the first robot 2 retreats to a safe position and returns to continue to take the precisely positioned packaging box for hot stamping;

[0047] 5. After the hot stamping of the packaging box is completed and the first robot 2 retreats to a safe position, the second robot 4 grabs the hot stamped packaging box, rotates the packaging box to a certain angle according to the process requirements and places it on the transfer machine 5 for transfer printing. After it is placed in place, the second robot 4 retreats to a safe position and returns to continue to take the hot stamped packaging box for transfer printing;

[0048] 6. After the transfer of the packaging box is completed and the second robot 4 retreats to a safe position, the third robot 6 grabs the packaging box that has been transferred and places it on the unloading conveyor line 8; after being placed in place, the third robot 6 retreats to a safe position and continues to grab the packaging box that has been transferred and unload it;

[0049] 7. If the box body needs to be turned, the third robot 6 directly places the transferred packaging box on the flipping device 7. After being placed in place, the third robot 6 retreats to a safe position to continue grabbing the transferred packaging box for unloading, and then the flipping device 7 flips the packaging box and places it on the unloading conveyor line 8.

[0050] The present invention uses the high-speed, flexible and high-precision characteristics of standardized robots to achieve high-intensity box hot stamping / transfer printing, simplify manual workload, improve product yield and improve production efficiency. The packaging boxes come in a variety of sizes and specifications. The packaging box hot stamping / transfer printing robot workstation is controlled by a PLC program, and various specifications and sizes of packaging boxes can be automatically hot stamped / transferred. It can complete a series of process processes such as automatic positioning, hot stamping, transfer, and flipping of liquor packaging boxes of different types and shapes, and realize unmanned production of hot stamping / transfer printing of liquor packaging boxes, which not only reduces the labor intensity of workers, but also improves the stability and quality of products.
