Description

Technical Field

[0001] This utility model relates to the technical field of integrated packaging devices, and more specifically, to a product collection flipping mechanism. 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] During cigarette production, cigarette packs must be inspected before being packaged. Only after the cigarette boxes pass inspection are they provided to the packaging line, allowing the finished cigarettes to be automatically packed into the inspected boxes. Currently, to minimize damage to the inspected boxes during transport from the inspection line to the packaging line and ensure quality, the boxes are manually packed and stacked before being transferred to the packaging line by forklift. However, in the existing inspection line, the boxes are placed flat on the conveyor. Since the thickness of cigarette boxes is generally between 15mm and 25mm, even when vertically conveyed onto the pushing mechanism, the boxes only stand sideways on the mechanism's worktable, making it difficult for robotic arms to directly handle them. Utility Model Content

[0004] The purpose of this utility model is to provide a product collection flipping mechanism that allows cigarette packs pushed out by the pushing mechanism to flip over, so that the cigarette packs enter the subsequent product collection station in an upright state, thereby facilitating the subsequent robot to clamp and pack the cigarette packs, and greatly improving the packing efficiency of the cigarette packs.

[0005] To achieve the purpose of this utility model, the technical solution adopted is as follows: a product collection flipping mechanism, including a base, a worktable on the base, an installation port in the middle of the worktable, and a flipping structure installed in the installation port; the flipping structure has a receiving groove that can accommodate multiple products, and the flipping structure is connected to both sides of the installation port before flipping and after flipping, respectively, and the flipping structure also has a pushing structure that pushes the products out of the receiving groove.

[0006] Furthermore, the flipping structure also includes a rotating shaft rotatably mounted on the base, and a fixed plate extending along its diameter is mounted on the rotating shaft. The pushing structure includes a movable plate that can reciprocate along its extension direction on the fixed plate, and the inner side of the movable plate and the inner side of the fixed plate cooperate to form a receiving groove.

[0007] Furthermore, the pushing structure includes two linear pairs mounted on the fixed plate and extending along its extension direction, a movable plate jointly mounted on the output end of the two linear pairs, and a linear drive element one mounted on the fixed plate, the output end of the linear drive element one being connected to the output end of the movable plate or the linear pairs.

[0008] Furthermore, two linear drive elements are hinged to the worktable. The output end of the linear drive element is hinged with a curved arm, and the extension ends of the two curved arms are respectively connected to the two ends of the rotating shaft.

[0009] Furthermore, the fixing plate is U-shaped, with two linear pairs installed on both sides of the fixing plate, and there are two linear drive elements. The two linear drive elements are installed on both sides of the back of the fixing plate, and the output end of the linear drive element is connected to the output end of the linear pair located on the same side by a connecting plate.

[0010] Furthermore, two guide strips are installed on the opposite surfaces of the fixed plate and the movable plate, and the end of the guide strip on the movable plate away from the fixed plate is bent outward.

[0011] The beneficial effects of this utility model are: This invention enables the cigarette packs pushed out by the pushing mechanism to be flipped, so that the cigarette packs enter the subsequent product collection station in an upright state.

[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 , Figure 2 As shown, the present invention provides a product collection flipping mechanism, including a base 24, on which a worktable 20 is provided. In actual use, the two ends of the worktable 20 are respectively used to install a pushing mechanism for pushing products and a product collection station for flipping products. To facilitate the smooth entry of cigarette packs pushed by the pushing mechanism into the product collection station after the flipping mechanism, an installation port 220 is provided in the middle of the workbench 20. The installation port 220 is located between the pushing mechanism installed on the workbench 20 and the product collection station. The flipping structure also has a receiving groove 225 for accommodating cigarette boxes. The length of the receiving groove 225 is not less than the width of the pushing mechanism, and the receiving groove 225 is in an open state. Before the flipping structure is flipped, the opening of the receiving groove 225 corresponds to the pushing mechanism, so that the cigarette packs pushed by the pushing mechanism can smoothly enter the receiving groove 225. At the same time, in order to ensure that the cigarette packs in the receiving groove 225 can smoothly enter the product collection station after the flipping structure is flipped, the receiving groove 225 on the flipping structure corresponds to the feeding side of the product collection station after the flipping structure is flipped. The flipping structure also has a pushing structure, which can push the cigarette packs in the receiving groove 225 into the product collection station after the flipping structure is flipped.

[0018] To ensure that the opening of the receiving slot 225 of the flipping structure aligns with the pushing mechanism before flipping, the opening of the receiving slot 225 of the flipping structure is flush with the worktable 20. Furthermore, to ensure that the opening of the receiving slot 225 of the flipping structure aligns with the product collection station after flipping, the opening of the receiving slot 225 of the flipping structure is flush with the support surface of the product collection station. Therefore, for the installation of the flipping structure, the worktable 20 also has an installation port 220 located between the pushing mechanism and the feeding side of the product collection station, and the flipping structure is installed within this installation port 220.

[0019] In this utility model, the flipping structure also includes a rotating shaft 221 rotatably mounted on the base 24 via a bearing seat. The central axis of the rotating shaft 221 is lower than the worktable 20, and a fixing plate 222 is mounted on the rotating shaft 221. The extension direction of the fixing plate 222 is parallel to the diameter direction of the rotating shaft 221. When the rotating shaft 221 is not rotating, the fixing plate 222 extends vertically upwards towards the worktable 20 through the mounting opening 220. At the same time, the pushing structure includes a movable plate 224 that can reciprocate in the extension direction of the fixing plate 222. The movable plate 224 is located on the side of the fixing plate 222 closer to the pushing mechanism, and the extension direction of the movable plate 224 is perpendicular to the extension direction of the fixing plate 222. When the rotating shaft 221 is not rotating and the moving plate 224 is not moving on the fixed plate 222, the bearing surface of the moving plate 224 for carrying the cigarette pack is flush with the worktable 20. At this time, the cigarette pack pushed by the pushing mechanism can smoothly enter the moving plate 224. When the rotating shaft 221 drives the moving plate 224 and the fixed plate 222 to rotate 90 degrees, the cigarette pack carried by the moving plate 224 is changed to be carried by the fixed plate 222. At this time, the bearing surface of the fixed plate 222 for carrying the cigarette pack is flush with the support surface of the product collection station. With the movement of the moving plate 224 on the fixed plate 222, the cigarette pack carried by the fixed plate 222 is pushed by the moving plate 224 to the support surface of the product collection station.

[0020] That is, the receiving groove 225 on the flipping structure is formed by the cooperation of the moving plate 224 and the fixed plate 222. The receiving groove 225 is L-shaped. Before the flipping structure flips, the opening of the receiving groove 225 corresponds to the pushing mechanism. After the flipping structure flips, the opening of the receiving groove 225 corresponds to the feeding side of the product collection station.

[0021] In this invention, to prevent the cigarette pack from falling out from both sides of the fixed plate 222 and the movable plate 224 due to the flipping of the flipping structure after entering the receiving slot 225, guide strips 230 can also be installed on both sides of the fixed plate 222 and both sides of the movable plate 224. When the flipping structure is not flipped, the guide strips 230 on the movable plate 224 are aligned with the guide strips 230 between the pushing mechanism and the flipping structure, while the guide strips 230 on both sides of the fixed plate 222 correspond to the guide strips 230 on both sides of the movable plate 224. At the same time, in order to ensure that the cigarette pack located in front of the push box plate 211 can smoothly enter between the two guide strips 230 on the movable plate 224 when pushed by the pushing mechanism, the ends of the two guide strips 230 on the movable plate 224 away from the fixed plate 222 can be bent outward, so that the inlet end of the channel formed by the two guide strips 230 on the fixed plate 222 is funnel-shaped.

[0022] To enable the movable plate 224 to reciprocate on the fixed plate 222, the pushing structure includes two slide rails mounted on the fixed plate 222. The two slide rails are spaced apart along the width of the fixed plate 222, and each slide rail is equipped with a slider. The slide rails and sliders together form a linear joint 223. The movable plate 224 is mounted on the sliders of the two linear joints 223. When the movable plate 224 reciprocates on the fixed plate 222, the linear joints 223 guide the movement of the movable plate 224. The linear motion of plate 224 is more precise; the pushing structure also includes a linear drive element 226 mounted on the fixed plate 222. The extension and retraction direction of the linear drive element 226 is consistent with the reciprocating motion direction of the moving plate 224 on the fixed plate 222, and the output end of the linear drive element 226 is connected to the slider on the moving plate 224 or the linear pair 223, so that when the linear drive element 226 extends and retracts, it drives the slider on the moving plate 224 and the linear pair 223 to move along the slide rail on the linear pair 223.

[0023] In order to drive the rotating shaft 221 to rotate, so that the rotating shaft 221 can drive the fixed plate 222 and the moving plate 224 to flip when rotating, two linear drive elements 228 can be hingedly installed on the upper surface of the worktable 20, the lower surface of the worktable 20, or the machine base 24. The two linear drive elements 228 are located on both sides of the worktable 20 or the two sides of the machine base 24, and the two linear drive elements 228 correspond to the two ends of the rotating shaft 221. The output ends of the two linear drive elements 228 are hinged with bent arms 229, and the extension ends of the two bent arms 229 are respectively installed on the two ends of the rotating shaft 221. When the two linear drive elements 228 extend or retract, both linear drive elements 228 drive the two ends of the rotating shaft 221 to rotate via the swing arm, allowing the rotating shaft 221 to rotate forward or backward within a 90-degree range. This causes the fixed plate 222 and the moving plate 224 to rotate 90 degrees on the rotating shaft 221, thus allowing the cigarette box stored in the receiving slot 225 to rotate 90 degrees. In this invention, to meet the rotation requirements of the rotating shaft 221, the linear drive elements 228 can also be replaced by a stepper motor. In this case, there can be only one stepper motor, which is mounted on the base 24, and the output end of the stepper motor is connected to one end of the rotating shaft 221 by a coupling.

[0024] In this invention, the fixed plate 222 is designed to be U-shaped. During installation, the slide rails in the two linear couplings 223 can be installed on both sides of the fixed plate 222. By setting the fixed plate 222 to a U-shape, the extension length at the middle of the fixed plate 222 is less than the extension lengths on both sides in the width direction. This allows the moving plate 224 to move directly out of the middle of the extension end of the fixed plate 222 when guided by the linear couplings 223. This ensures that when the cigarette pack is carried by the fixed plate 222, the moving plate 224 can directly push the cigarette pack out of the fixed plate 222, thus guaranteeing that the cigarette pack after being flipped by the flipping structure can enter the product collection station. In this invention, when the fixed plate 222 is U-shaped, the mounting opening 220 on the worktable 20 is also U-shaped to ensure that the worktable 20 does not obstruct the flipping structure during flipping.

[0025] To make the movement of the mounting plate on the fixed plate 222 smoother, two linear drive elements 226 can be used. In this case, the two linear drive elements 226 are located on both sides of the fixed plate 222, and the output ends of the two drive elements 226 are connected to the sliders on the two linear pairs 223, or the output ends of the two drive elements 226 are connected to both ends of the moving plate 224. At the same time, in order to avoid the width of the fixed plate 222 being too large due to the installation of linear drive elements 226 on both sides of the fixed plate 222, the linear drive elements 226 can also be directly installed on the back of the fixed plate 222, and a connecting plate 227 can be connected between the output end of the linear drive elements 226 and the side of the slider in the linear pair 223 or the side of the moving plate 224, so that when the linear drive elements 226 extend or retract, they can drive the sliders on the moving plate 224 and the linear pair 223 to slide along the slide rail on the linear pair 223.

[0026] In this invention, the linear drive element 226 and the linear drive element 228 are both one of the following: cylinder, hydraulic rod, and electronic telescopic rod. The specific selection of the linear drive element 226 and the linear drive element 228 can be determined according to the actual situation.

[0027] When the cigarette packs pushed by the pushing mechanism need to be flipped during their entry into the product collection station, the cigarette packs pushed by the pushing mechanism enter the receiving groove 225, and the moving plate 224 lifts the cigarette packs that have entered the receiving groove 225. Then, the linear drive element 1 210 retracts and drives the pusher plate 211 to move backward, so that the pusher plate 211 is reset. During this process, the linear drive element 228 extends and drives the rotating shaft 221 to rotate 90 degrees to the side of the product collection station through the bent arm 229. At the same time as the rotating shaft 221 rotates, it drives the fixed plate 222, the moving plate 224, the linear drive element 1 226, and the linear coupling 223 to rotate synchronously, so that the fixed plate 222 aligns with the product collection station, and the moving plate 224 is vertical. At this time, the cigarette packs pass through the fixed plate 222. The robot lifts the cigarette packs, placing them upright on the fixed plate 222. Then, linear drive element 226 retracts, moving the movable plate 224 towards the extension end of the fixed plate 222. Simultaneously, the movable plate 224 pushes the cigarette packs on the fixed plate 222 towards the product collection station. After the cigarette packs enter the product collection station, linear drive element 226 extends, resetting the movable plate 224. Linear drive element 228 retracts and, through the bent arm 229, rotates the rotating shaft 221 90 degrees. Simultaneously, the rotating shaft 221 rotates, causing the fixed plate 222, movable plate 224, linear drive element 226, and linear coupling 223 to rotate synchronously, aligning the movable plate 224 with the worktable 20 and the receiving slot 225 with the pushing mechanism. This process is repeated, ensuring the cigarette packs pushed by the pushing mechanism are neatly rotated and placed into the product collection station. Once the neatly arranged cigarette packs fill the product collection station, the robot clamps and transfers the cigarette packs from the collection station.

[0028] Of course, the flipping mechanism provided by this utility model can not only be used in cigarette pack production lines to flip cigarette packs pushed out by the pushing mechanism, but also in packaging production lines with similar external dimensions to cigarette boxes, such as pharmaceuticals.

[0029] 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.
