Description

Technical Field

[0001] This utility model relates to the technical field of integrated packaging devices, and more specifically, to a cigarette pack pushing 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 during transport. Since the thickness of cigarette boxes is generally between 15mm and 25mm, the robotic arm cannot directly grip the boxes after they are conveyed. Utility Model Content

[0004] The purpose of this utility model is to provide a cigarette pack pushing mechanism, which allows the cigarette pack to enter the front of the pushing mechanism in a side-standing position after being sent out by the conveying device, so that the cigarette pack pushed out by the pushing mechanism can be easily gripped by the robotic arm, thereby facilitating the subsequent packing of the cigarette pack.

[0005] To achieve the purpose of this utility model, the technical solution adopted is as follows: a cigarette pack pushing mechanism, including a base and a worktable located on the base, a pushing mechanism is installed on the worktable, and the output end of the conveying device is perpendicular to the worktable and located on one side of the pushing mechanism; the output end of the conveying device also has a push box mechanism for pushing the product forward of the pushing mechanism.

[0006] Furthermore, the pusher mechanism includes a through hole on the conveying surface of the conveying device, and a pusher block that can move forward and backward in the through hole, and a drive structure for driving the pusher block is also installed at the output end of the conveying device.

[0007] Furthermore, the conveying device is also equipped with a linear pair whose extension direction is consistent with the movement direction of the pusher block, and the pusher block is fixedly installed at the output end of the linear pair.

[0008] Furthermore, the drive structure includes a pusher motor mounted on the back of the conveying device, with a connecting rod eccentrically connected to the output end of the pusher motor, and the extension end of the connecting rod connected to the pusher block.

[0009] Furthermore, the pushing mechanism includes a linear drive element supported on the worktable by a bracket, and a pusher plate is also installed at the output end of the linear drive element.

[0010] Furthermore, the workbench is also equipped with guide bars arranged at intervals. Two guide bars are located between the push mechanism and the output end of the conveying device, and the feed ends of the two guide bars are respectively connected to the two sides of the output end of the conveying device.

[0011] Furthermore, a cover plate is also supported on the workbench. The cover plate is located on the upper part in front of the pusher plate, and the feed end of the cover plate is connected to the output end of the conveying device.

[0012] The beneficial effects of this utility model are: In this invention, by making the output end of the conveying device perpendicular to the worktable, the cigarette packs sent by the conveying device are directly placed sideways on the worktable. In conjunction with the pusher mechanism installed at the output end of the conveying device, the sideways cigarette packs are directly pushed into front of the pusher mechanism, making it easier for the robot arm to grip the cigarette packs pushed by the pusher mechanism, thus facilitating the subsequent packing of the cigarette packs.

[0016] 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.

[0017] 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.

[0018] like Figures 1 to 4 As shown, the present invention provides a cigarette pack pushing mechanism, including a base 24, a worktable 20 on the base 24, and the output end of the conveying device 1 perpendicular to the worktable 20, so that after the cigarette pack is conveyed to the worktable 20 by the conveying device 1, the cigarette pack is perpendicular to the worktable 20. That is, when the cigarette pack is on the worktable 20, the length direction of the cigarette pack is consistent with the pushing direction of the pushing mechanism 21, and the width direction of the cigarette pack on the worktable 20 is consistent with the vertical direction, that is, the cigarette pack stands sideways on the worktable 20.

[0019] When the output end of the conveying device 1 is perpendicular to the worktable 20, the forward direction of the cigarette packs conveyed by the conveying device 1 is not the same as the direction in which the cigarette packs enter the front of the pushing mechanism 21 from one side. Therefore, in order to ensure that the cigarette packs conveyed by the conveying device 1 can sequentially enter the front of the pushing mechanism 21 after entering the worktable 20, a pusher mechanism 10 is also installed at the output end of the conveying device 1. The pushing direction of the pusher mechanism 10 extends horizontally and is perpendicular to the pushing direction of the pushing mechanism 21. When the cigarette packs are conveyed to the worktable 20 by the conveying device 1, the cigarette packs are perpendicular to the worktable 20 and parallel to the conveying surface of the conveying device 1. At this time, the pusher mechanism 10 pushes the cigarette packs, causing them to be sequentially squeezed into the front of the pushing mechanism 21 in a vertical state.

[0020] In this utility model, since the output end of the conveying device 1 is perpendicular to the worktable 20, in order to prevent the cigarette packs from falling directly onto the worktable 20 when being conveyed by the conveying device 1, a guide strip parallel to the conveying surface of the conveying device is also installed on the conveying device 1. The distance between the guide strip and the conveying surface of the conveying device 1 is adapted to the thickness of the cigarette pack. At the same time, there is a certain distance between the discharge end of the guide strip and the worktable 20, and the distance between the discharge end of the guide strip and the worktable 20 is not less than the width of one cigarette pack. This ensures that when the pushing mechanism 10 pushes the cigarette packs that have entered the worktable 20, the cigarette packs will not be blocked by the guide strip, so that the cigarette packs sent out by the conveying device 1 can be pushed sequentially to the front of the pushing mechanism 21 by the pushing mechanism 10.

[0021] In this utility model, such as Figure 2 , Figure 3 As shown, the pusher mechanism 10 includes a through hole 100 formed on the conveying surface of the conveying device 1. When the cigarette pack is sent out by the conveying device 1 and is perpendicular to the worktable 20, the through hole 100 corresponds to the center of the cigarette pack. The pusher mechanism 10 also includes a pusher block 104 located in the through hole 100. The pusher block 104 is clearance-fitted with the through hole 100, allowing the pusher block 104 to move forward or backward smoothly within the through hole 100. When the pusher block 104 moves forward, it pushes the cigarette pack located at the output end of the conveying device 1 forward. When the pusher block 104 moves backward, the output end of the conveying device 1 is vacated, allowing the next cigarette pack on the conveying device 1 to enter the output end of the conveying device 1. A drive structure is also installed on the back of the conveying device 1. The drive structure drives the pusher block 104, causing the pusher block 104 to move forward and backward automatically within the through hole 100.

[0022] A linear coupling 102 is also installed on the back of the conveying device 1. The linear coupling 102 includes a slide rail whose extension direction is consistent with the movement direction of the pusher block 104. The linear coupling 102 also includes a slider that can slide on the slide rail, and the rear end of the pusher block 104 is directly mounted on the slider. At the same time, the drive structure also includes a pusher motor 101 installed on the back of the conveying device 1. An eccentric wheel is installed at the output end of the pusher motor 101, and a connecting rod 103 is hinged to the eccentric wheel. The extension end of the connecting rod 103 is hinged to the rear end of the pusher block 104 or the slider in the linear coupling 102. Through the cooperation of the slide rail and the slider on the linear coupling 102, when the pusher motor 101 rotates, the pusher motor 101 drives the slider and the pusher block 104 forward or backward through the connecting rod 103, thereby causing the pusher block 104 to push the cigarette pack forward.

[0023] In this invention, to enable the pushing mechanism 21 to push the neatly arranged cigarette packs in front of it, the pushing mechanism 21 includes a linear drive element 210 mounted on the workbench 20 via a support, and a pusher plate 211 is also installed at the output end of the linear drive element 210. When the linear drive element 210 is not activated, the pusher plate 211 is located on the side of the cigarette packs away from the product collection station 23. By pushing the pusher plate 211 with the linear drive element 210, the cigarette packs located in front of the pusher plate 211 are pushed forward toward the product collection station 23.

[0024] To prevent the cigarette packs from shifting laterally as they are pushed forward by the pusher mechanism 10 towards the pusher mechanism 21, two guide bars 22 are installed on the worktable 20. These guide bars 22 are located between the pusher mechanism and the output end of the conveyor device 1. The inlet ends of the two guide bars 22 are respectively aligned with the two sides of the output end of the conveyor device 1, and the outlet ends are flush. When the linear drive element 210 is not pushing the pusher plate 211 forward, one of the guide bars 22 is aligned with one end of the pusher plate 211. Through the cooperation of the two guide bars 22 and the worktable 20, a guide channel corresponding to the pusher mechanism 10 is formed on the worktable 20. The inlet end of this guide channel is aligned with the output end of the conveyor device 1, and the outlet end is aligned with one end of the pusher plate 211, thus allowing the cigarette packs pushed forward by the pusher mechanism 10 to be sequentially squeezed forward within the guide channel.

[0025] In this utility model, in order to make the cigarette pack bounce upward when it enters the front of the pusher plate 211, two L-shaped brackets can be installed on the worktable 20. The vertical part of the brackets is installed on the worktable 20, and a cover plate 23 is installed on the two brackets. The height of the cover plate 23 is slightly higher than the height of the cigarette pack standing on the worktable, and the feed end of the cover plate 23 is connected to the output end of the conveying device 1. When the linear drive element 210 does not push the pusher plate 211 forward, one side of the cover plate 23 is located above the upper edge of the pusher plate 211, and the other end of the cover plate 23 extends in the forward direction of the pusher plate 211.

[0026] In this invention, to prevent the cigarette pack from shifting along the length of the pusher plate 211 when pushed by the pusher mechanism 21, guide strips can also be installed in front of the pusher mechanism 21. Specifically, there are two guide strips in front of the pusher mechanism 21, each corresponding to one end of the pusher plate 211. When the pusher mechanism 21 is not in operation, one end of the guide strip away from the pusher mechanism 10 is located outside the pusher plate 211, and the other end of the guide strip extends to the mounting opening 220; the end of the guide strip closer to the pusher mechanism 10 is connected to a guide strip used to guide the cigarette pack pushed out by the pusher mechanism 10. By installing two guide strips in front of the pusher mechanism 21, a guide channel for guiding the cigarette pack is formed in front of the pusher mechanism 21, so that the cigarette pack located in front of the pusher plate 211 can move forward neatly when the pusher mechanism 21 pushes the cigarette pack towards the flipping mechanism 22.

[0027] In this invention, the linear drive element 210 is one of a cylinder, a hydraulic rod, or an electronic telescopic rod, and the specific selection of the linear drive element 210 can be determined according to the actual situation. In this invention, in order to make the push box plate 211 move more smoothly, two guide rods arranged in opposite directions can be installed on the push box plate 211, and a sliding sleeve that slides with the guide rods is installed on the base 24.

[0028] When cigarette packs from the product conveyor 1 on the cigarette pack production line need to be boxed, as the cigarette packs are delivered from the product conveyor 1 and stand upright on the worktable 20, the box-pushing motor 101 rotates. During the rotation of the box-pushing motor 101, the box-pushing block 104 is driven by the connecting rod 103, causing the box-pushing block 104 to move forward or backward within the through hole 100. When the box-pushing block 104 moves forward, it pushes the cigarette packs standing upright on the worktable 20 forward, causing them to move in front of the box-pushing plate 211. When the box-pushing block 104 moves backward, because the cigarette packs at the output end of the product conveyor 1 are pushed forward and the output end of the product conveyor 1 is no longer blocked by the box-pushing block 104, the next cigarette pack on the product conveyor 1 automatically enters the output end of the product conveyor 1 and stands upright on the worktable 20. This process is repeated, so that the cigarette packs delivered by the product conveyor 1 are pushed sequentially in front of the box-pushing plate 211.

[0029] When the cigarette packs, which are standing upright on the workbench 20, are neatly placed in front of the pusher plate 211, the linear drive element 210 extends and drives the pusher plate 211 forward, so that the cigarette packs, which are neatly arranged in front of the pusher plate 211, are pushed forward.

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.
