Abstract
Description
Technical Field
[0001] This utility model relates to a paper box processing equipment, and more particularly to a stacked paper box flipping and conveying mechanism. Background Technology
[0002] In the packaging and printing industry, after cardboard boxes are formed by a gluing machine, they typically need to be counted and transported by a box-feeding and counting mechanism. A certain number of cardboard boxes are then stacked vertically to facilitate subsequent robotic handling, packing, or palletizing processes. However, in actual production, after the cardboard boxes are stacked vertically, some manufacturers require the glued edges of the boxes to be oriented upwards or downwards when packing them into boxes. In this case, the entire stack of cardboard boxes needs to be rotated 180° to adjust the orientation of the glued edges.
[0003] Currently, the industry mainly uses manual flipping or simple clamps to assist in flipping stacks of cardboard boxes, which has many technical shortcomings:
[0004] Manual flipping is inefficient and labor-intensive: manual lifting and flipping of the entire stack of cardboard boxes is cumbersome and time-consuming, which cannot meet the continuous operation requirements of high-speed gluing production lines and significantly increases the labor intensity of workers.
[0005] The flipping angle cannot be precisely controlled, making it easy for the stack to fall apart and deform: manual or simple clamps lack stable clamping and support structures, and are mostly manually adjusted, making it difficult to accurately achieve a 180° flip. During the flipping process, the cardboard box stacks are prone to tilting, falling apart, and deforming due to uneven force, which cannot meet the manufacturer's directional packing requirements.
[0006] Poor versatility and insufficient adaptability: The existing flipping clamp is a fixed structure, which cannot adjust the clamping and support size according to the width and height of the cardboard stack. It can only adapt to a single specification of cardboard stack, resulting in insufficient adaptability. Utility Model Content
[0007] The problem to be solved by this utility model is to provide a whole stack of paper boxes flipping and conveying mechanism. This whole stack of paper boxes flipping and conveying mechanism can precisely flip the whole stack of paper boxes 180°, improve the flipping efficiency, reduce the labor intensity of workers, and meet the requirements of directional packing.
[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0009] A stacked paper box flipping and conveying mechanism includes a frame, a paper feeding platform, and a moving mechanism capable of driving the paper feeding platform to move horizontally. The moving mechanism is mounted on the frame, and the paper feeding platform is movably mounted on the frame. The mechanism further includes a lifting frame, a flipping strip suction cup, and two grippers. The lifting frame is vertically movable and mounted on the frame. The paper feeding platform is located below the lifting frame and can move horizontally below it. The flipping strip suction cup is rotatably mounted on the lifting frame and is located above the paper feeding platform. The two grippers are movably mounted at both ends of the flipping strip suction cup. The flipping strip suction cup has a paper feeding adsorption surface for placing the stacked paper boxes. The paper feeding adsorption surface has multiple air holes communicating with the inner cavity of the flipping strip suction cup. The paper feeding adsorption surface is located within the gripping area of the two grippers. The frame has a first lifting mechanism capable of driving the lifting frame to move up and down. The lifting frame has a flipping drive mechanism capable of driving the flipping strip suction cup to rotate 180°. The flipping strip suction cup has an opening and closing drive mechanism capable of driving the two grippers to open and close.
[0010] Before use, first, drive the paper feeding platform horizontally to directly below the lifting frame via the moving mechanism; then, drive the lifting frame upward via the first lifting mechanism to leave enough space between the flipping strip suction cup and the paper feeding platform below for the flipping strip suction cup to complete a 180° rotation, avoiding interference between the flipping strip suction cup, grippers, and paper feeding platform during the flipping process; next, drive the flipping strip suction cup to rotate via the flipping drive mechanism, so that the paper feeding suction surface on the flipping strip suction cup faces upward, and the two grippers are also set upward synchronously with the flipping strip suction cup, ready to receive the paper box stack; finally, connect the flipping strip suction cup to the external negative pressure supply device.
[0011] When it is necessary to flip the glued edges of a stack of cardboard boxes, first activate the negative pressure supply device. An external paper-picking robot then smoothly places a neat stack of cardboard boxes onto the paper-feeding surface of the flipping suction cup, which holds the entire stack in place. Next, the opening and closing drive mechanism drives the two grippers at both ends of the flipping suction cup to close synchronously, stably clamping the stack on the paper-feeding surface and fixing its position to prevent displacement or scattering during the flipping process. Then, the flipping drive mechanism drives the flipping suction cup to rotate precisely 180°, causing the grippers and the held stack of cardboard boxes to flip synchronously, adjusting the glued edges of the stack. The paper is moved to the preset upward or downward position, meaning the paper suction surface, grippers, and the stack of paper boxes being held are all facing downwards. After the flipping is completed, the lifting frame is driven downwards by the first lifting mechanism, so that the two grippers on the flipping strip suction cup approach the paper feeding platform. Finally, the two grippers are driven to open synchronously by the opening and closing drive mechanism, releasing the gripping of the paper box stack. At the same time, the negative pressure supply device is turned off, so that the paper suction surface of the flipping strip suction cup is released from negative pressure, releasing the suction on the entire stack of paper boxes. The flipped paper box stack is then placed smoothly on the paper feeding platform. The paper feeding platform is then driven horizontally to another operating position by the moving mechanism, thus completing one round of paper box stack flipping and conveying operation.
[0012] In a preferred embodiment, the first lifting mechanism includes a first linear guide rail, a first slide groove, a first gear, a first rack, and a first servo motor. The first rack is mounted on the frame and is vertically oriented. The first linear guide rail is mounted on the lifting frame and is vertically oriented. The first slide groove is mounted on the frame, and the first linear guide rail is located within and can move along the first slide groove. The first servo motor is mounted on the frame, and the first gear is mounted on the power output shaft of the first servo motor, meshing with the first rack. The first servo motor drives the lifting frame to move up and down on the first linear guide rail, thereby driving the tilting drive mechanism, the tilting strip suction cup, the opening and closing drive mechanism, and the two grippers.
[0013] In a preferred embodiment, the flipping drive mechanism includes a second servo motor, a hollow rotating platform, and bearings. Both the second servo motor and the hollow rotating platform are mounted on the lifting frame. The power output shaft of the second servo motor is connected to the hollow rotating platform. One end of the flipping strip suction cup is connected to the hollow rotating platform, and the other end of the flipping strip suction cup is rotatably mounted on the lifting frame via bearings. The hollow rotating platform is a high-precision indexing rotating structure. The second servo motor drives the hollow rotating platform to rotate, thereby driving the flipping strip suction cup to rotate precisely 180°.
[0014] In a preferred embodiment, the opening and closing drive mechanism includes a third servo motor, a second gear, two first rack guide slots, two second racks, two second linear guides, two second sliders, and two first translation seats. The third servo motor, the two second linear guides, and the two first rack guide slots are all mounted on the flip-type suction cup. The two second linear guides are parallel to the length direction of the flip-type suction cup. The two second sliders are respectively mounted on the corresponding second linear guides and can move on the corresponding second linear guides. The two first translation seats are respectively mounted on the corresponding second sliders, and the two grippers are respectively mounted on the corresponding first translation seats. The openings of the two first rack guide slots are arranged opposite each other, and the two second racks are respectively located in the corresponding first rack guide slots and can move in the corresponding first rack guide slots. The two second racks are parallel to the second linear guides. The left end of one second rack is connected to the left first translation seat, and the right end of the other second rack is connected to the right first translation seat. The second gear is mounted on the power output shaft of the third servo motor, and the second gear is located between and meshes with the two second racks. The second gear is driven to rotate by the third servo motor, and the two second racks move synchronously in opposite directions along the guide groove of the first rack, which drives the two first translation seats and their grippers to move synchronously in opposite directions along the length of the flipping strip suction cup, thus realizing the opening and closing action of the grippers.
[0015] In a preferred embodiment, a sponge layer is laid on the paper-feeding adsorption surface of the flip-type suction cup, and the sponge layer has multiple first through holes corresponding to the air holes. The sponge layer is made of a flexible and elastic material, and it is in surface contact with the bottom surface of the cardboard stack, avoiding scratches on the printed surface caused by direct contact between the rigid paper-feeding adsorption surface and the cardboard box.
[0016] In a preferred embodiment, the stacked cardboard box flipping and conveying mechanism further includes two second lifting mechanisms, two clamping columns, and a translational drive mechanism capable of driving the two second lifting mechanisms to move closer or further away. The paper-laying platform has two vertically penetrating strip-shaped guide holes aligned on the same straight line. The translational drive mechanism is installed at the bottom of the paper-laying platform. The power output ends of the second lifting mechanisms face upwards. The two clamping columns are respectively installed on the power output ends of the corresponding second lifting mechanisms, and are positioned below the corresponding strip-shaped guide holes, allowing them to move up and down within those holes. The clamping columns rise and fall through the strip-shaped guide holes, coordinating with the synchronous approach and clamping of the translational drive mechanism. This accurately positions the flipped cardboard box stack at a preset position on the paper-laying platform, preventing stack misalignment during loading and ensuring the accuracy of subsequent packing and palletizing processes, eliminating the need for manual handling.
[0017] In a further preferred embodiment, the translation drive mechanism includes a fourth servo motor, a third gear, two second rack guide slots, two third racks, two third linear guides, two pairs of third sliders, two second translation seats, and two clamping supports. The fourth servo motor, the two third linear guides, and the two second rack guide slots are all installed at the bottom of the paper feeding platform. The two third linear guides are parallel to the strip-shaped guide holes, and the two strip-shaped guide holes are located between the two third linear guides. Each pair of third sliders is installed on a corresponding third linear guide and can move on the corresponding third linear guide. The two ends of the second translation seats are respectively installed on the corresponding two third sliders, and the clamping supports are installed on the corresponding second translation seats. The second lifting mechanism is mounted on a corresponding clamping support. The second translational support has a first guide hole corresponding to the strip-shaped guide hole, and the clamping column is positioned within the corresponding first guide hole. The openings of two second rack guide grooves are arranged opposite each other, and two third racks are respectively positioned within and movable within their respective second rack guide grooves. Both third racks are parallel to the strip-shaped guide holes, and the two strip-shaped guide holes are located between the two third racks. The left end of one third rack is connected to the left side of the second translational support, and the right end of the other third rack is connected to the right side of the second translational support. A third gear is mounted on the power output shaft of the fourth servo motor, positioned between and meshing with the two third racks. Driven by the fourth servo motor, the third gear rotates, causing the two third racks to move synchronously in opposite directions along the second rack guide grooves, thus driving the two second lifting mechanisms to move closer or further away from the strip-shaped guide holes.
[0018] In a further preferred embodiment, the second lifting mechanism includes a lifting cylinder and a clamping block. The cylinder body of the lifting cylinder is mounted on the clamping support, the piston rod of the lifting cylinder is arranged facing upward, the clamping block is mounted on the end of the piston rod of the lifting cylinder, and the lower end of the clamping column is mounted on the clamping block.
[0019] The aforementioned moving mechanism is existing technology and will not be described in detail here. The moving mechanism can employ a structure consisting of a motor, lead screw, guide rod, guide sleeve, and nut; it can also employ a structure consisting of a motor, gear, rack, guide rail, and slider; or it can employ a structure consisting of a motor, driving sprocket, driven sprocket, chain, guide rail, and slider.
[0020] Compared with the prior art, this utility model has the following advantages:
[0021] (1) This utility model relies on the coordinated action of the first lifting mechanism, the flipping drive mechanism, the opening and closing drive mechanism and the moving mechanism to realize the fully automated flipping process of "receiving-clamping-flipping-discharging-conveying", without manual intervention, improving flipping efficiency, adapting to the continuous operation requirements of high-speed gluing production line, and reducing the labor intensity of workers.
[0022] (2) The paper-feeding adsorption surface of this utility model provides rigid support for the bottom of the paper box stack. The two claws close and clamp from both sides simultaneously, forming a double fixing structure of "bottom support and side clamping". During the flipping process, the paper box stack is subjected to uniform force, which completely avoids skewing and scattering. In addition, the clamping distance of the two claws can be flexibly adjusted according to the width of the paper box stack. At the same time, the paper-feeding adsorption surface of the flipping strip suction cup can be adapted to paper box stacks of different heights. Without replacing the core components, it can be adapted to flipping paper box stacks of various sizes and specifications, with good adaptability.
[0023] (3) The flipping drive mechanism of this utility model can precisely control the flipping strip suction cup to rotate 180°, with no deviation in the flipping angle, ensuring that the glued edge of the cardboard stack is precisely adjusted to the preset state of facing up or down, which fully matches the manufacturer's directional packing requirements.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0030] like Figure 1-5As shown, the stacked paper box flipping and conveying mechanism in this embodiment includes a frame 1, a paper feeding platform 2, a lifting frame 3, a flipping strip suction cup 4, and two grippers 5, and a moving mechanism (not shown) capable of driving the paper feeding platform 2 to move horizontally. The moving mechanism is mounted on the frame 1, the paper feeding platform 2 is movably mounted on the frame 1, the lifting frame 3 is vertically movable and mounted on the frame 1, the paper feeding platform 2 is located below the lifting frame 3 and can move horizontally below the lifting frame 3, and the flipping strip suction cup 4 is rotatably mounted on the lifting frame 3, and the flipping strip suction cup 4 is located above the paper feeding platform 2. Two grippers 5 are movably mounted at both ends of the flip-type suction cup 4. The flip-type suction cup 4 is provided with a paper-feeding adsorption surface 41 for placing the stack of paper boxes. The paper-feeding adsorption surface 41 is provided with multiple air holes 42 that communicate with the inner cavity of the flip-type suction cup 4. The paper-feeding adsorption surface 41 is located in the clamping area of the two grippers 5. The frame 1 is provided with a first lifting mechanism 6 that can drive the lifting frame 3 to move up and down.

The flip-type suction cup 4 is provided with an opening and closing drive mechanism 8 that can drive the two grippers 5 to open and close.
[0031] Before use, the paper feeding platform 2 is first moved horizontally to directly below the lifting frame 3 by the moving mechanism; then the lifting frame 3 is moved upward by the first lifting mechanism 6, so that enough space is reserved between the flipping strip suction cup 4 and the paper feeding platform 2 below to allow the flipping strip suction cup 4 to complete a 180° rotation, so as to avoid interference between the flipping strip suction cup 4, the gripper 5 and the paper feeding platform 2 during the flipping; next, the flipping drive mechanism 7 drives the flipping strip suction cup 4 to rotate, so that the paper feeding adsorption surface 41 on the flipping strip suction cup 4 faces upward, and the two grippers 5 are also set upward synchronously with the flipping strip suction cup 4, ready to receive the paper box stack; finally, the flipping strip suction cup 4 is connected to the external negative pressure supply device.
[0032] When it is necessary to flip the glued edge of a stack of cardboard boxes, first activate the negative pressure supply device. An external paper-picking robot then smoothly places a neat stack of cardboard boxes onto the paper-feeding suction surface 41 of the flipping strip suction cup 4, which holds the entire stack in place. Next, the opening and closing drive mechanism 8 drives the two grippers 5 at both ends of the flipping strip suction cup 4 to close synchronously, stably clamping the stack of cardboard boxes on the paper-feeding suction surface 41 and fixing its position to prevent displacement or scattering during the flipping process. Then, the flipping drive mechanism 7 drives the flipping strip suction cup 4 to rotate precisely 180°, causing the grippers 5 to flip synchronously with the clamped stack of cardboard boxes, adjusting the glued edge of the stack to the correct position. The preset upward or downward state means that the paper-feeding suction surface 41, the grippers 5, and the clamped cardboard stack are all facing downward. After the flipping is completed, the lifting frame 3 is driven downward by the first lifting mechanism 6, so that the two grippers 5 on the flipping strip suction cup 4 are close to the paper-feeding platform 2. Finally, the two grippers 5 are driven to open synchronously by the opening and closing drive mechanism 8, releasing the gripping of the cardboard stack. At the same time, the negative pressure supply device is turned off, so that the paper-feeding suction surface 41 of the flipping strip suction cup 4 is released from negative pressure, releasing the suction of the entire stack of cardboard boxes. The flipped cardboard stack is then placed smoothly on the paper-feeding platform 2. The paper-feeding platform 2 is then driven horizontally to another operating position by the moving mechanism, thus completing one round of cardboard stack flipping and conveying operation.
