[0009] Further, the front labeling mechanism, the transfer member and the back labeling mechanism are distributed in sequence from left to right; after the front labeling mechanism completes the front labeling of the material, the material is flipped counterclockwise upward and moved into the transfer member, and the back labeling mechanism flips the material counterclockwise downward, moves the material out of the transfer member and then labels the back side of the material.

[0010] Further, the front labeling mechanism can move up and down relative to the frame. A first guiding mechanism is arranged between the front labeling mechanism and the frame. When the front labeling mechanism moves up and down, the first guiding mechanism enables the front labeling mechanism to rotate relative to the frame and move left and right relative to the frame at the same time; when the front labeling mechanism moves upward, the first guiding mechanism enables the front labeling mechanism to rotate counterclockwise upward and move left at the same time.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment: As Figure 1-8 shown, the double-sided flipping type automatic labeling device for electronic ship tickets includes a frame 1, and a conveying mechanism 2, a loading mechanism 3, a labeling mechanism 4, a laser mechanism 5, and a blanking mechanism 6 provided on the frame 1. The loading mechanism 3, the labeling mechanism 4, the laser mechanism 5, and the blanking mechanism 6 are sequentially distributed along the conveying mechanism 2 from left to right. The labeling mechanism 4 includes:

[0032] A transfer member 41, provided on one side of the conveying mechanism 2, for temporarily storing materials;

[0033] A front labeling mechanism 42, provided on one side of the conveying mechanism 2, for front-labeling the materials and moving the materials from the conveying mechanism 2 into the transfer member 41 after the labeling is completed;

[0034] A back labeling mechanism 43, provided on one side of the conveying mechanism 2, for moving the materials with the front labeling completed from the transfer member 41 back to the conveying mechanism 2 and back-labeling the materials;

[0035] A label conveying mechanism 44, provided on one side of the conveying mechanism 2, for conveying labels.

[0036] Among them, the trays carrying materials sequentially pass through the loading mechanism 3, the labeling mechanism 4, the laser mechanism 5, and the blanking mechanism 6 along the conveying mechanism 2.

[0037] Specifically, the front labeling mechanism 42, the transfer member 41, and the back labeling mechanism 43 are distributed in sequence from left to right. After the front labeling mechanism 42 completes the front labeling of the material, it turns the material counterclockwise upward to move the material into the transfer member 41. The back labeling mechanism 43 turns the material counterclockwise downward to move the material out of the transfer member 41 and then labels the back of the material.

[0038] Specifically, the front labeling mechanism 42 includes a first mounting frame 421 movably connected to the frame 1 and a first suction head 422 provided on the first mounting frame 421. The first suction head 422 is externally connected to a gas source and sucks the material through negative pressure. The back labeling mechanism 43 includes a second mounting frame 431 movably connected to the frame 1 and a second suction head 432 provided on the second mounting frame 431. The second suction head 432 is externally connected to a gas source and sucks the material through negative pressure.

[0039] The labeling steps for the material (such as an electronic ticket) are as follows: First, the material is conveyed by the conveying mechanism 2 from the loading mechanism 3 to the labeling mechanism 4. Then, the front labeling mechanism 42 sucks the label on the label conveying mechanism 44 and then pastes the label on the front of the material. Next, the front labeling mechanism 42 adsorbs the material from the front of the material and rotates counterclockwise upward to move the material into the transfer member 41. At this time, the front of the material faces left and the back faces right. Then, the back labeling mechanism 43 adsorbs the material from the back of the material and rotates counterclockwise downward to move the material out of the transfer member 41. At this time, the back of the material faces upward. Then, the material is placed back into the carrier of the conveying mechanism 2. Next, the back labeling mechanism 43 sucks the label on the label conveying mechanism 44 and then pastes the label on the back of the material. At this time, the front and back of the material have been labeled. Then, the material is conveyed by the conveying mechanism 2 to the laser mechanism 5 for laser processing. Finally, the processed material is conveyed by the conveying mechanism 2 to the unloading mechanism 6 for unloading.

[0040] In summary, the above structure realizes the automatic labeling of the front and back of the material, as well as automatic laser processing, achieving the automation and mechanization of labeling and laser processing, reducing labor costs and improving production efficiency.

[0041] In an implementation manner, for optimizing the structure and facilitating implementation, the front labeling mechanism 42 can move up and down relative to the frame 1. A first guiding mechanism 7 is provided between the front labeling mechanism 42 and the frame 1. When the front labeling mechanism 42 moves up and down, the first guiding mechanism 7 causes the front labeling mechanism 42 to rotate relative to the frame 1 and move left and right relative to the frame 1. When the front labeling mechanism 42 moves upward, the first guiding mechanism 7 causes the front labeling mechanism 42 to rotate counterclockwise upward and move leftward at the same time. Wherein, when the front labeling mechanism 42 rotates counterclockwise upward and moves leftward, materials can be moved into the transfer member 41. After the materials enter the transfer member 41, the front labeling mechanism 42 releases the materials. The front labeling mechanism 42 moves downward, and the first guiding mechanism 7 causes the front labeling mechanism 42 to rotate clockwise downward and move rightward to reset at the same time.

[0042] In an implementation manner, for optimizing the structure and facilitating implementation, a first power mechanism 10 is provided on the frame 1. The front labeling mechanism 42 is rotatably connected to the output end of the first power mechanism 10. The first guiding mechanism 7 includes a first guiding wheel 71 provided on the front labeling mechanism 42 and a first guiding groove 72 formed on the frame 1. When the first power mechanism 10 drives the front labeling mechanism 42 to move up and down, the first guiding wheel 71 slides along the first guiding groove 72 to cause the front labeling mechanism 42 to rotate relative to the frame 1 and move left and right at the same time. Specifically, when the front labeling mechanism 42 moves upward, the first guiding wheel 71 slides along the first guiding groove 72 to cause the front labeling mechanism 42 to rotate counterclockwise upward and move leftward at the same time.

[0043] Specifically, the first mounting bracket 421 is rotatably connected to the output end of the first power mechanism 10. The first guiding wheel 71 and the first suction head 422 are both connected to the first mounting bracket 421. Wherein, after the front labeling mechanism 42 rotates counterclockwise upward by 90°, the first suction head 422 faces the transfer member 41, and the materials are completely moved into the transfer member 41.

[0044] In an implementation manner, for optimizing the structure and facilitating implementation, the first guiding groove 72 includes a first groove section 721, a second groove section 722 and a third groove section 723 connected in sequence from bottom to top. The first groove section 721 is located on the right side of the third groove section 723, and the second groove section 722 extends obliquely in the left-right direction. More preferably, chamfers are provided at the joints of the second groove section 722 with the first groove section 721 and the third groove section 723.

[0045] In an embodiment, to optimize the structure and facilitate implementation, the back labeling mechanism 43 can move up and down relative to the frame 1. A second guiding mechanism 8 is provided between the back labeling mechanism 43 and the frame 1. When the back labeling mechanism 43 moves up and down, the second guiding mechanism 8 causes the back labeling mechanism 43 to rotate relative to the frame 1 and move left and right relative to the frame 1 at the same time. When the back labeling mechanism 43 moves downward, the second guiding mechanism 8 causes the back labeling mechanism 43 to rotate counterclockwise downward and move left at the same time. Specifically, when the back labeling mechanism 43 moves upward, the second guiding mechanism 8 causes the back labeling mechanism 43 to rotate clockwise upward and move right at the same time. After the back labeling mechanism 43 moves into place, it adsorbs the material. Then the back labeling mechanism 43 moves downward, and the second guiding mechanism 8 causes the back labeling mechanism 43 to rotate counterclockwise downward and move left, moving the material out of the transfer member 41. After the back labeling mechanism 43 swings downward into place, it releases the material, causing the material to fall onto the carrier plate on the conveying mechanism 2, and finally labeling is performed.

[0046] In an embodiment, to optimize the structure and facilitate implementation, a second power mechanism 9 is provided on the frame 1. The back labeling mechanism 43 is rotatably connected to the output end of the second power mechanism 9. The second guiding mechanism 8 includes a second guiding wheel 81 provided on the back labeling mechanism 43 and a second guiding groove 82 formed on the frame 1. When the second power mechanism 9 drives the back labeling mechanism 43 to move up and down, the second guiding wheel 81 slides along the second guiding groove 82, causing the back labeling mechanism 43 to rotate relative to the frame 1 and move left and right at the same time. Specifically, when the back labeling mechanism 43 moves downward, the second guiding wheel 81 slides along the second guiding groove 82, causing the back labeling mechanism 43 to rotate counterclockwise downward and move left at the same time.

[0047] Specifically, the second mounting bracket 431 is rotatably connected to the output end of the second power mechanism 9. The second guiding wheel 81 and the second suction head 432 are connected to the second mounting bracket 431. Among them, when the back labeling mechanism 43 rotates 90° clockwise upward, the second suction head 432 faces the transfer member 41. After the back labeling mechanism 43 rotates 90° counterclockwise downward, the material is completely moved out of the transfer member 41, and the back labeling mechanism 43 is reset.

[0048] In one embodiment, for optimizing the structure and facilitating implementation, the second guiding groove 82 includes a fourth groove section 821, a fifth groove section 822, and a sixth groove section 823 that are connected in sequence from bottom to top. The fourth groove section 821 is located on the left side of the sixth groove section 823, and the fifth groove section 822 extends obliquely in the left-right direction. More preferably, chamfers are provided at the joints of the fifth groove section 822 with the fourth groove section 821 and the sixth groove section 823.

[0049] In one embodiment, for facilitating the transfer of materials into or out of the transfer member 41, the front labeling mechanism 42 and the back labeling mechanism 43 are symmetrically arranged with respect to the transfer member 41.

[0050] In one embodiment, for facilitating the transfer of materials into or out of the transfer member 41, the transfer member 41 includes two chucks 411 that move closer to or away from each other in the front-rear direction. When the two chucks 411 move closer to each other, they cooperate to form a receiving space for receiving materials.

[0051] In one embodiment, for optimizing the structure and facilitating implementation, the conveying mechanism 2 includes a third power mechanism 21 provided on the frame 1 and a conveyor belt 22 that rotates under the drive of the third power mechanism 21.

[0052] In one embodiment, for optimizing the structure and facilitating implementation, the feeding mechanism 3 includes a first loading turntable 31, a first loading cylinder 32, a discharging push rod (not shown in the figure), a transfer table 33, a first transfer arm 34, and a fourth power mechanism (not shown in the figure) provided on the frame 1. The first loading turntable 31 is an annular conveyor chain, the first loading cylinder 32 is provided on the first loading turntable 31, there are several first loading cylinders 32, and each first loading cylinder 32 is distributed circumferentially along the first loading turntable 31. The transfer table 33 is provided on one side of the first loading turntable 31. The discharging push rod pushes the materials in the first loading cylinder 32 that has rotated to one side of the transfer table 33 to the transfer table 33 under the drive of the fourth power mechanism, and the first transfer arm 34 transfers the materials on the transfer table 33 to the carrier on the conveying mechanism 2.

[0053] In one embodiment, for optimizing the structure and facilitating implementation, the laser mechanism 5 is an existing laser machine.

The second material-carrying turntable 61 is an annular conveyor chain. The second material-carrying cylinder 62 is arranged on the second material-carrying turntable 61. There are several second material-carrying cylinders 62, and each of the second material-carrying cylinders 62 is circumferentially distributed along the second material-carrying cylinder 62. The second transfer arm 63 transfers the material from the tray on the conveyor belt 22 into the second material-carrying cylinder 62. More preferably, the conveyor belt 22 includes a first conveyor belt (not marked in the figure) and a second conveyor belt (not marked in the figure) arranged side by side. The first conveyor belt is used to convey the tray carrying the material, and the second conveyor belt is used to convey the empty tray.

[0055] It should be understood that in the present invention, terms such as "first" and "second" are used to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, the "first" information can also be called the "second" information. Similarly, the "second" information can also be called the "first" information. In addition, the orientation or positional relationship indicated by terms such as "center of the circle", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present invention.

[0056] As described above, one or more implementation manners are provided in combination with specific content, and it is not determined that the specific implementation of the present invention is only limited to these descriptions. Any implementation similar or identical to the method and structure of the present invention, or any implementation obtained by making several technical deductions or substitutions under the premise of the inventive concept of the present invention, should be regarded as within the protection scope of the present invention.
