[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] like Figure 1-6 The high-speed carton labeling device shown in the figure includes a body 10, a first worktable 11, a second worktable 12, and a workpiece transfer mechanism. The first worktable 11 and the second worktable 12 are both mounted on the body 10 and spaced apart along the length of the body 10. The workpiece transfer mechanism can transfer workpieces from the first worktable 11 to the second worktable 12.

[0025] A positioning assembly is provided on the first workbench 11 to position the workpiece. Furthermore, a marking mechanism 50 is provided on the second workbench 12. Specifically, the marking mechanism 50 comprises a marking roller 51, a first drive assembly, and a second drive assembly. The marking roller 51 is positioned above the second workbench 12 and, driven by the first drive assembly, moves along the length of the machine body 10. Driven by the second drive assembly, the marking roller 51 moves along the height of the machine body 10.

[0026] On the basis of the above structure, when using the high-speed carton labeling device of the present invention, the carton to be labeled can be placed on the first workbench 11 by an external manipulator, and the carton to be labeled can be positioned under the action of the positioning component of the first workbench 11. The positioned carton can be moved to the second workbench 12 under the action of the workpiece transfer mechanism, and the label is affixed to the surface of the carton by the external manipulator. Thereafter, the first driving component drives the label pressing roller 51 along the height direction of the machine body 10, and after the label pressing roller 51 moves downward, it moves downward and contacts the label on the workpiece. Subsequently, the second driving component drives the label pressing roller 51 to move along the length direction of the machine body 10, that is, the label pressing roller 51 moves back and forth, and drives out the bubbles between the label and the workpiece, thereby improving the labeling accuracy and labeling quality.

[0027] It should be noted that the above-mentioned label pressing mechanism 50 can be set at one end of the second workbench 12, and a pressure plate mechanism 60 is set at the other end of the second workbench 12. The pressure plate mechanism 60 includes a pressure plate 61 and a pressure plate cylinder 62. The cylinder body of the pressure plate cylinder 62 can be fixedly connected to the machine body 10. The piston rod of the pressure plate cylinder 62 extends along the height direction of the machine body 10. The pressure plate 61 is located above the second workbench 12 and is fixedly connected to the piston rod of the pressure plate cylinder 62. The extension and contraction of the piston rod of the pressure plate cylinder 62 can drive the pressure plate 61 to move up and down. In this way, when labeling and removing bubbles in the label paper, the pressure plate 61 can be driven downward by the pressure plate cylinder 62 to press against the end of the paper box to prevent displacement of the pressure roller 51 during the labeling process.

[0028] Furthermore, the first drive assembly includes a first cylinder 52 and a first guide rail. Both the first guide rail and the piston rod of the first cylinder 52 extend along the length of the machine body 10. A drive plate is provided on the piston rod of the first cylinder 52, which slidably engages the drive plate with the first guide rail. Furthermore, the second drive assembly includes a second cylinder 53 and a second guide rail. Both the second guide rail and the piston rod of the second cylinder 53 extend along the height of the machine body 10. The marking roller 51 is fixedly connected to the piston rod of the second cylinder 53 via a connecting arm 54; the connecting arm 54 slidably engages the second guide rail.

[0029] In this way, when driving the marking roller 51 to move along the height direction of the machine body 10, the piston rod of the second cylinder 53 can be extended and retracted to drive the connecting arm 54 to move up and down, thereby driving the marking roller 51 connected to the connecting arm 54 to move up and down, and the sliding cooperation between the connecting arm 54 and the second guide rail can guide the marking roller 51 up and down, and the up and down movement structure is stable.

[0030] When driving the marking roller 51 to move along the length of the machine body 10, the piston rod of the first cylinder 52 can be extended and retracted, driving the driving plate to move along the length of the machine body 10, thereby driving the marking roller 51 mounted on the driving plate to move along the length of the machine body 10. Similarly, the sliding fit between the driving plate and the first guide rail can guide the marking roller 51 to move stably along the length of the machine body 10.

[0031] Furthermore, the label pressing roller 51 can be selected as a rubber roller, which contacts the label paper to prevent the label paper from being scratched during the process of removing bubbles.

[0032] Of course, the first drive assembly and the second drive assembly can both be implemented by screw transmission mechanisms or other linear motion output mechanisms such as linear motors in the prior art.

[0033] Furthermore, in this embodiment, the positioning assembly includes a first fixed block 111, a first movable block 112, a second fixed block 113, and a second movable block 114. The first fixed block 111 and the first movable block 112 are both mounted on the first workbench 11 and spaced apart in the longitudinal direction of the machine body 10. The first movable block 112 can move toward or away from the first fixed block 111. In addition, the second fixed block 113 and the second movable block 114 are both mounted on the second workbench 12 and spaced apart in the width direction of the machine body 10. The second movable block 114 can move toward or away from the second fixed block 113.

[0034] Based on the above structure, after the external manipulator places the carton on the first workbench 11, it can move toward the first fixed block 111 through the first movable block 112, and the first movable block 112 and the first fixed block 111 can respectively abut against the two sides of the carton. At the same time, the second movable block 114 moves toward the second fixed block 113, and the second movable block 114 and the second fixed block 113 respectively abut against the two sides of the carton, that is, the first movable block 112, the first fixed block 111, the second movable block 114 and the second fixed block 113 can abut and limit the four sides of the carton to correct the position of the carton on the first workbench 11.

[0035] More specifically, the positioning assembly further includes a positioning slot 115, a positioning rod, and a first elastic component 116. The positioning slot 115 is disposed on the first workbench 11, and the positioning rod is disposed within the positioning slot 115, extending along the length of the machine body 10. Furthermore, a positioning hole is provided at the bottom end of the first movable block 112, into which the positioning rod is inserted and slidably engaged. Furthermore, the first elastic component 116 is sandwiched between the first movable block 112 and the wall of the positioning slot 115. The first elastic component 116 is configured to provide a first elastic stress that causes the first movable block 112 to move toward the second fixed block 113.

[0036] On the basis of this structure, when the carton is placed on the first workbench 11, the side of the carton can compress the first elastic component 116 during the placement process, and the first movable block 112 can move away from the first fixed block 111 to facilitate the placement of the carton. After the carton is placed, the first elastic component 116 is reset to drive the first movable block 112 to abut against the side of the carton for positioning.

[0037] It should be noted that the first workbench 11 may be provided with a second movable block cylinder 117 , and the piston rod of the second movable block cylinder 117 may be extended and retracted to drive the second movable block 114 to move toward or away from the second fixed block 113 .

[0038] Furthermore, in this embodiment, a plurality of the first workbench 11 and the second workbench 12 are provided, and the plurality of first workbench 11 and the second workbench 12 are staggered in the longitudinal direction of the machine body 10. In the actual labeling process, after the label paper is affixed, the labeled cartons need to be inspected. Based on this structure, the first workbench 11 located at the front end in the longitudinal direction of the machine body 10 can be used to position the cartons, and the workpiece transfer mechanism transfers the cartons on the first workbench 11 to the second workbench 12 behind it. After the labeling is completed after the second workbench 12 and the bubbles are removed, the workpiece transfer mechanism transfers the labeled cartons to the first workbench 11 behind the second workbench 12. After positioning, the cartons are inspected by the inspection camera on the machine body 10.

[0039] After that, the workpiece transfer mechanism transfers the paper box after inspection to the second workbench 12 behind it to carry out labeling operation of another label paper. In this way, the workpiece transfer mechanism pushes the paper box down in turn, and performs positioning, labeling, positioning re-inspection, labeling, etc. back and forth. The first workbench 11 and the second workbench 12 are set up according to the actual number of label papers that need to be affixed.

[0040] Furthermore, there is a support plate 20, a plurality of transfer platforms 21, a first drive mechanism 30 and a second drive mechanism 40. The support plate 20 extends along the longitudinal direction of the body 10, and the plurality of transfer platforms 21 are fixed to the support plate 20, and the transfer platforms 21 are spaced apart in the longitudinal direction of the body 10. In addition, a mounting seat 41 is provided on the power output end of the second drive mechanism 40. Driven by the second drive mechanism 40, the mounting seat 41 moves along the longitudinal direction of the body 10, and the first drive mechanism 30 and the support plate 20 are both mounted on the mounting seat 41. In this way, when the mounting seat 41 moves along the longitudinal direction of the body 10, the first drive mechanism 30 and the support plate 20 can both move along the longitudinal direction of the body 10. In addition, a transfer space 118 for the transfer platform 21 to pass through is provided in the middle of the first workbench 11 and the second workbench 12.

[0041] Specifically, the first drive mechanism 30 includes a driver, a first guide 34, and a second guide 35. The driver is mounted on a mounting base 41, and the first guide 34 is synchronously connected to the power output of the driver and, driven by the driver, moves along the length of the machine body 10. The second guide 35 is fixed to the bottom end of the support plate 20 and can flexibly cooperate with the first guide 34. When the first guide 34 moves along the length of the machine body 10, it guides the second guide 35 to move along the height of the machine body 10, thereby causing the support plate 20 to move along the height of the machine body 10.

[0042] On the basis of the above structure, when the workpiece is transferred, the paper box is placed on the first workbench by an external manipulator for positioning, and the transfer platform 21 located at the front end in the length direction of the body 10 can be driven by the second driving mechanism 40 to move along the length direction of the body 10 to the transfer space 118 of the first workbench 11. Thereafter, the driving member is started to drive, and the first guide member 34 moves forward along the length direction of the body 10. At this time, the second guide member 35 on the support plate 20 can cooperate with the first guide member 34 to guide the support plate 20 to move in the height direction of the body 10, so that the transfer platform 21 on the support plate 20 moves upward, and the transfer platform 21 is The paper box positioned on the first workbench 11 can be lifted up, and then the second driving mechanism 40 drives the support plate 20 to move backward as a whole by one station, and the transfer platform 21 supporting the paper box moves to the transfer space 118 of the second workbench 12. After that, the driving member drives the first guide member 34 to move backward along the length direction of the machine body 10. At this time, the second guide member 35 on the support plate 20 can cooperate with the first guide member 34 to guide the support plate 20 to move in the height direction of the machine body 10, so that the transfer platform 21 on the support plate 20 moves downward, and the transfer platform 21 can place the positioned paper box on the second workbench 12, thus completing the transfer.

[0043] When there are multiple first work tables 11 and second work tables 12, the multiple transfer tables 21 correspond to the transfer spaces 118 of the first work tables 11 and the second work tables 12 at various positions, and the transfer is completed synchronously, which improves the work efficiency.

[0044] At the same time, the second driving mechanism 40 can drive the mounting seat 41 to move in the length direction of the body 10, so that the multiple transfer platforms 21 on the support plate 20 move in the length direction of the body 10, and then drive the corresponding workpieces to complete the transfer in the length direction. The synchronization is high, and the first driving mechanism 30 and the second driving mechanism 40 can operate simultaneously without the need for interval operation, saving time.

[0045] Furthermore, in this embodiment, the first guide member 34 includes a guide block, and a guide slope is provided at the top of the guide block. The guide slope is inclined from top to bottom in the longitudinal direction of the body 10. Correspondingly, the second guide member 35 includes a roller, which is used to roll with the guide slope. Based on this structure, the guide block is connected to the power output end of the drive member, and the roller can be pivoted to the bottom end of the support plate 20. When the drive member is activated, it can drive the guide block to move along the longitudinal direction of the body 10. At this time, the roller can roll along the guide slope. By rolling along the inclined guide slope, it can move from top to bottom or from bottom to top, driving the support plate 20 to move in the height direction of the body 10.

[0046] Of course, the first guide member 34 may also be an arch member, and the roller of the second guide member 35 rolling along the arch member may also drive the support plate 20 to move in the height direction of the machine body 10 .

[0047] Furthermore, the first drive mechanism 30 further includes a second elastic member 36, one end of which is connected to the mounting base 41, and the other end of which is connected to the bottom end of the support plate 20. The second elastic member 36 is used to provide an elastic stress that causes the support plate 20 to move downward. Based on this structure, driven by the drive member, the first guide member 34 and the second guide member 35 slide together to guide the support plate 20 to move upward, and the second elastic member 36 is stretched. When the support plate 20 moves downward, the second elastic member 36 resets, providing a second elastic stress that causes the support plate 20 to move downward, allowing the support plate 20 to quickly reset.

[0048] It should be noted that the second elastic component 36 in this embodiment can be implemented by a spring in the prior art.

[0049] Furthermore, the first drive mechanism 30 also includes a guide mechanism for guiding the support plate 20 in the height direction of the machine body 10. Specifically, the guide mechanism includes a guide rod and a guide sleeve 37. The guide sleeve 37 is fixed to the mounting base 41, and the guide rod is fixed to the bottom end of the support rod; the guide rod slidably penetrates the guide rod. Based on this structure, when the support plate 20 moves in the height direction of the machine body 10, the guide rod can slide with the guide sleeve 37 to guide the support plate 20 in its up and down motion, making the motion structure more stable.

[0050] Furthermore, the above-mentioned driving member includes a first motor 31, a first screw rod 32, a first nut 33 and a first guide mechanism. The first motor 31 is installed on the body 10, and the first screw rod 32 extends along the length direction of the body 10 and is synchronously connected to the rotating shaft of the first motor 31; the first nut 33 is threadedly mounted on the outer surface of the first screw rod 32 and moves along the extension direction of the first screw rod 32 under the guidance of the first guide mechanism; the first nut 33 forms the power output end of the driving member; the first guide member 34 is fixedly connected to the first nut 33.

[0051] When driving the above-mentioned support plate 20 to move in the height direction, the first motor 31 can be started. The above-mentioned first guide mechanism includes a slide rail arranged along the length direction of the machine body 10 and a slider fixedly connected to the first guide member 34, so that the slider is slidably mounted on the slide rail. When the first motor 31 is started, the rotating shaft of the first motor 31 can drive the first screw rod 32 to rotate. The rotation of the first screw rod 32 can drive the first nut 33 threadedly engaged with it to rotate. The rotational movement of the first nut 33 is limited by the cooperation between the slider and the slide rail, and thus can be converted into a linear motion along the extension direction of the first screw rod 32, thereby driving the first guide member 34 fixed thereto to move along the length direction of the machine body 10, thereby sliding relative to the second guide member 35 at the bottom end of the support plate 20, guiding the support plate 20 to move up and down.

[0052] Of course, the above-mentioned driving member can also be realized by other linear motion output mechanisms in the prior art such as linear motors and electric slides. However, the use of a screw transmission mechanism as the driving member has the advantages of high speed and high precision.

[0053] Furthermore, the second drive mechanism 40 includes a second motor 42, a second screw rod 43, a second nut and a second guide mechanism. The second motor 42 is installed on the body 10, and the second screw rod 43 extends along the length direction of the body 10 and is synchronously connected to the rotating shaft of the second motor 42; the second nut is threadedly mounted on the outer surface of the second screw rod 43 and moves along the extension direction of the screw rod under the guidance of the second guide mechanism; the second nut forms the power output end of the second drive mechanism 40; and a mounting seat 41 is fixed to the second nut.

[0054] Similarly, the structure of the second guide mechanism can be the same as the structure of the above-mentioned first guide mechanism. The slider is fixedly connected to the bottom end of the mounting seat 41, and the slide rail is fixed on the body 10. When the support plate 20 is driven to move in the length direction of the body 10, the second motor 42 is started, and the rotating shaft of the second motor 42 can drive the second screw rod 43 to rotate. The rotation of the second screw rod 43 can drive the second nut threadedly engaged with it to rotate. The rotational movement of the second nut is limited by the cooperation between the slider and the slide rail, and can be converted into a linear motion along the extension direction of the second screw rod 43, thereby driving the mounting seat 41 fixed thereto to move along the length direction of the body 10, thereby driving the support plate 20 on the mounting seat 41 to move synchronously.

[0055] Furthermore, a vacuum suction cup assembly 211 is provided on the transfer platform 21. The vacuum suction cup assembly 211 is commercially available. The specific structure and operating principle of the vacuum suction cup assembly 211 are known to those skilled in the art from existing technologies and will not be described in detail here. The vacuum suction cup assembly 211 stably holds the workpiece on the transfer platform 21, preventing it from falling during transfer. Furthermore, vacuum suction does not damage the workpiece.

[0056] Those skilled in the art can make various other corresponding changes and deformations based on the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the present invention.
