Description

Technical Field

[0001] This utility model relates to the technical field of integrated packaging devices, specifically to a clamping mechanism and robot for stacking cigarette packaging boxes. Background Technology

[0002] Cigarettes are tobacco products made by rolling tobacco shreds into strips using cigarette paper; they are also called paper cigarettes, cigarettes, or cigarette rolls. There are filtered cigarettes and unfiltered cigarettes, and they are also available in mild and strong flavors. Chinese cigarettes are mainly classified into four types based on their raw materials: ① Flue-cured type, using flue-cured tobacco as raw material, popular in countries such as Britain, China, India, and Canada; ② Blended type, using flue-cured, sun-cured, and air-cured tobacco as raw material, now popular worldwide; ③ Spiced type (Oriental type), using aromatic tobacco as raw material, popular in Turkey, Greece, the former Soviet Union, and Eastern European countries; ④ Sun-cured type, using dark sun-cured tobacco as raw material, popular in Southern Europe and parts of Africa.

[0003] In the cigarette production process, cigarette packs need to be inspected before being packaged. Only after the cigarette boxes pass inspection are they provided to the cigarette packaging production line, allowing the finished cigarettes to be automatically packed into the inspected boxes. Currently, to minimize damage to the inspected cigarette boxes during transport from the inspection line to the packaging line and ensure quality, manual packing and palletizing of the inspected boxes are often performed after inspection, followed by forklift transport to the packaging line. This operation is inefficient, labor-intensive, and increases labor costs, hindering companies from improving production efficiency and reducing costs. Therefore, to improve the efficiency of packing and palletizing cigarette boxes, a palletizing robot has been proposed to handle both packing and palletizing. However, existing clamping mechanisms cannot simultaneously hold both the cigarette boxes and the packaging boxes containing them, requiring two robotic arms to work together. This not only increases equipment costs but also requires significant space during installation. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping mechanism and robot for stacking cigarette packs. It can not only clamp neatly arranged cigarette packs, but also the packaging boxes containing cigarette packs, so that the stacking of cigarette packs can be completed by a single robotic arm, which greatly reduces equipment costs and installation space requirements.

[0005] To achieve the purpose of this utility model, the technical solution adopted is as follows: a clamping mechanism for stacking cigarette packaging boxes, including a base installed at the output end of a robotic arm, the shape of which is adapted to the inside of the packaging box, and flip-able clamps are installed on all four sides of the base; one of the clamps is also equipped with a tray that can extend into or retract from the base.

[0006] Furthermore, the base is equipped with side plates on all four sides, and a rotatable drive shaft is supported on the side plates. Multiple connecting arms are installed on the drive shaft, and clamps are installed on the connecting arms.

[0007] Furthermore, one of the drive shafts is also equipped with a mounting bracket, on which a linear drive element is mounted, and a support plate is mounted on the output end of the linear drive element.

[0008] Furthermore, a rotary drive element for driving the transmission shaft to rotate is also installed on the side plate.

[0009] Furthermore, the rotary drive element is a rotary cylinder.

[0010] A robot for palletizing cigarette packaging boxes includes a robotic arm and a gripping mechanism as described above, wherein the gripping mechanism is installed at the output end of the robotic arm.

[0011] The beneficial effects of this utility model are: This invention can not only clamp neatly arranged cigarette packs, but also clamp the packaging boxes containing the cigarette packs after the clamped cigarette packs are packed into boxes. This allows the packing and stacking of cigarette packs to be completed by a single robotic arm, greatly reducing equipment costs and the space required for installation. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings.

[0016] It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 As shown, this utility model provides a clamping mechanism for stacking cigarette packaging boxes, including a base 310. The shape and size of the base 310 are adapted to the shape and size of the inside of the packaging box, so that the clamping mechanism can clamp a pack of cigarettes that can fill the packaging box at once. In this utility model, both the base 310 and the inside of the packaging box are rectangular. Rotatable clamping plates 314 are installed around the base 310. Multiple clamping plates 314 work together. When the clamping plates 314 are flipped downwards, their lower edges are lower than the lower surface of the base 310. When the clamping mechanism needs to clamp cigarette packs collected in the product collection station, the neatly arranged cigarette packs in the product collection station are located below the base 310. Multiple clamping plates 314 flip downwards together, clamping the neatly arranged cigarette packs in the product collection station. In conjunction with the movement of the robotic arm 30, the clamped cigarette packs are transferred and packed into boxes.

[0018] In this invention, although the neatly arranged cigarette packs in the product collection station are not connected, and the multiple clamping plates 314 only clamp the cigarette packs located around the product collection station when clamping the neatly arranged cigarette packs in the product collection station, the cigarette packs located around the product collection station will be squeezed towards the center when each clamping plate 314 clamps the cigarette packs located around the product collection station, so that the adjacent cigarette packs located in the product collection station will be squeezed together, and the friction between two adjacent cigarette packs will increase. Thus, during the process of multiple clamping plates 314 jointly clamping and transporting the neatly arranged cigarette packs in the product collection station, the neatly arranged cigarette packs will not fall apart.

[0019] Furthermore, to grip the packaging box containing cigarette packs, the clamping mechanism includes a support plate 317 mounted on one of the clamping plates 314. The extension direction of the support plate 317 is perpendicular to the surface of the clamping plate 314. After the clamping plate 314 is flipped downwards on the base 310, the support plate 317 can extend downwards from the base 310 on the clamping plate 314, and the support plate 317 can also exit from below the base plate 4505 on the clamping plate 314. When the cigarette pack held by the clamping mechanism is placed into the packaging box, the support plate 317 extends downwards from the base 310 on the clamping plate 314, so that the support plate 317 is inserted under the packaging box. The support plate 317 lifts the packaging box, and together with the multiple clamping plates 314 gripping the cigarette pack, the packaging box containing the cigarette pack is clamped. In conjunction with the movement of the robotic arm 30, the packaging box containing the cigarette pack is transferred and stacked.

[0020] To facilitate the installation of the clamping plate 314, side plates 311 are installed on each side of the base 310. The lower edge of the side plate 311 does not extend beyond the lower surface of the base 310. A drive shaft 312, which is rotatably supported by a bearing seat, is also installed on the side plate 311. The length direction of the drive shaft 312 is consistent with the length direction of the clamping plate 314. Multiple connecting arms 313 are also installed on the drive shaft 312. The clamping plate 314 is installed on the extension ends of the multiple connecting arms 313 on the same drive shaft 312. This not only makes the flipping of the clamping plate 314 more stable, but also makes the force on both ends of the clamping plate 314 more balanced when clamping the cigarette pack, making the clamping plate 314 clamp the cigarette pack more secure.

[0021] To ensure the installation of the pallet 317, a mounting bracket 315 is also installed on one of the drive shafts 312. The mounting bracket 315 is L-shaped and a linear drive element 316 is installed on the mounting bracket 315. The extension and retraction direction of the linear drive element 316 is consistent with the movement direction of the pallet 317, and the pallet 317 is fixedly installed on the output end of the linear drive element 316, so that the linear drive element 316 can drive the pallet 317 to move forward or backward synchronously when it extends or retracts.

[0022] In this utility model, the mounting bracket 315 can also be fixed to the back of the rotating shaft 221 and the clamping plate 314 at the same time. In order to ensure that the packaging box remains stable on the tray 317 when the tray 317 is lifted, the central axis of the tray 317 is on the same straight line as the central axis of the base plate 4505.

[0023] To drive the flipping of the clamping plate 314, a rotary drive element 318 is installed on each side plate 311, and the output end of the rotary drive element 318 is connected to the transmission shaft 312, so that when the rotary drive element 318 rotates, it can drive the transmission shaft 312 to rotate synchronously, thereby driving the clamping plate 314 to flip through the connecting arm 313. In this utility model, the rotary drive element 318 is a rotary cylinder, which not only has sufficient power and a good clamping effect on the cigarette pack, but is also easy to control. Of course, when meeting the clamping requirements of the clamping plate 314 for the cigarette pack, the rotary drive element 318 can also be a stepper motor.

[0024] In this utility model, the linear drive element 316 is one of a cylinder, a hydraulic rod, or an electronic telescopic rod, and the specific selection of the linear drive element 316 can be determined according to the actual situation.

[0025] When it is necessary to clamp the neatly arranged cigarette packs, the lower surface of the base 310 contacts the cigarette packs collected in the product collection station. Then, the four rotary drive elements 318 drive the four transmission shafts 312 to rotate. While the four transmission shafts 312 rotate, they drive the four clamping plates 314 to flip downward through the connecting arms 313. The four clamping plates 314 work together to clamp the cigarette packs in the product collection station. After the cigarette packs are clamped by the four clamping plates 314, the linear drive element 316 extends and drives the tray 317 to insert under the pack, so that the pack containing the cigarette packs is clamped by the clamping mechanism.

[0026] Based on the above, this utility model also provides a robot, such as... Figure 2 As shown, it includes a robotic arm and a clamping mechanism as described above. The clamping mechanism is installed on the output end of the robotic arm 30. After clamping the cigarette packs collected in the product collection station and the packaging boxes containing the cigarette packs, the clamping mechanism can be driven by the robotic arm 30 to move, so that the cigarette packs clamped by the clamping mechanism can be put into the packaging boxes, and the packaging boxes containing the cigarette packs can be stacked.

[0027] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present invention.
