Description

Technical Field

[0001] The utility model relates to the technical field of packaging assembly line equipment, in particular to a guiding mechanism used for packaging quasi-conical cigarettes and a packaging assembly line. Background Art

[0002] Due to the unusual shape of cone-shaped cigarettes, they are typically conveyed directly onto traditional assembly lines. This prevents them from maintaining a consistent orientation, meaning that the ends of the cigarettes entering the assembly line cannot all face the same direction. This creates significant challenges for the robotic arm used for packaging on the assembly line. When the cone-shaped cigarettes are placed into boxes or bottles in the same orientation, if the ends of the two cones face each other, the suction cup arm must rotate 180° after grabbing the first one before retrieving the second. The arm's own weight and rotational speed create significant inertia, which often leads to malfunctions. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a guiding mechanism for packaging quasi-conical cigarettes, including a rolling plate for receiving the quasi-conical cigarettes and allowing the quasi-conical cigarettes to roll toward the side close to the assembly line under their own gravity; and a guide plate for receiving the quasi-conical cigarettes sliding down from the rolling plate and allowing the quasi-conical cigarettes to continue sliding down to the assembly line with the big end facing forward.

[0004] Based on the above solution, the rolling plate and the guide plate both form an angle of 20-26° with the horizontal plane.

[0005] Based on the above solution, a plurality of guide grooves are provided on the guide plate.

[0006] Based on the above solution, the guide groove is a V-shaped groove.

[0007] On the basis of the above solution, the length of the rolling plate for the quasi-conical smoke to roll down is 1.5-2.0 times the length of the quasi-conical smoke.

[0008] On the basis of the above solution, the length of the guide groove for the quasi-conical smoke to slide down is 1.1-1.6 times the length of the quasi-conical smoke.

[0009] On the basis of the above solution, it also includes a fixing part for fixing the guide mechanism as a whole at the feed end of the assembly line.

[0010] The present application also provides an assembly line for packaging quasi-conical cigarettes, including a guide mechanism arranged at the feed end of the assembly line for adjusting the quasi-conical cigarettes entering the assembly line to a posture with the large end facing forward, and the guide mechanism is the above-mentioned guide mechanism.

[0011] The guiding mechanism of the utility model can adjust the conical cigarettes into a uniform posture by their own gravity before entering the production line, thereby effectively reducing the operating difficulty of the robot used in the subsequent packaging process, and also reducing the failure rate of the robot, providing a good foundation for the next step of packaging, and greatly improving the packaging efficiency.

[0018] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1

[0020] like Figure 1 As shown, the quasi-conical cigarette described in this application refers to a cigarette with an overall cone-like shape, with one end (diameter A) being larger and the other end (diameter a) being smaller, with A > a. Quasi-conical cigarettes are made of a relatively soft material, with an outer layer of paper or tobacco leaves and an inner layer of shredded tobacco.

[0021] During packaging, due to the irregular shape and soft material of the cone-shaped cigarettes, if a conventional gripper-type robot is used, the cone-shaped cigarettes will be scratched due to the material problem of the cone-shaped cigarettes. Therefore, a suction cup-type robot needs to be used on the packaging line.

[0022] like Figure 3 As shown, on traditional assembly lines, quasi-conical cigarettes are directly delivered to the line. At this point, the quasi-conical cigarettes cannot maintain a consistent posture, meaning that the large or small ends of the quasi-conical cigarettes entering the line cannot all face the same direction. This poses a significant problem for the robotic arm used for packaging on the assembly line. Because, when the quasi-conical cigarettes are loaded into boxes or bottles in the same orientation, if the large or small ends of the two quasi-conical cigarettes in front and behind face each other, in order to ensure consistent orientation, the suction cup robot must rotate 180° after grabbing the first one before grabbing the second one. However, due to the weight and rotation speed of the suction cup robot, a significant amount of inertia is generated, which often causes the suction cup robot to malfunction. To solve this technical problem, it would be best to ensure that the quasi-conical cigarettes entering the line maintain the same posture, so that the suction cup robot does not need to rotate when grabbing.

[0023] The way that the quasi-conical smoke is conveyed to the assembly line in the same posture can be that the large ends of all the quasi-conical smoke enter the assembly line first, or the small ends of all the quasi-conical smoke enter the assembly line first; or all the quasi-conical smoke enters in other directions but all the quasi-conical smoke maintains the same posture.

[0024] like Figure 2 As shown, the utility model provides a guiding mechanism for packing quasi-conical cigarettes, the guiding mechanism comprising a rolling plate for receiving the quasi-conical cigarettes and allowing the quasi-conical cigarettes to roll toward a side close to the production line by their own gravity;

[0025] and

[0026] It is used to receive the quasi-conical smoke sliding down from the rolling plate 1 and allow the quasi-conical smoke to continue sliding down to the guide plate 2 of the assembly line along the posture of the big end facing forward.

[0027] When using, Figure 4 and Figure 5 As shown, the quasi-conical smoke passes through rolling plate 1 before entering assembly line b. On rolling plate 1, the quasi-conical smoke rolls downward under its own weight (the arc with the arrow indicates the direction of the quasi-conical smoke's rolling, and the straight line with the arrow indicates the direction of its overall movement). Because the quasi-conical smoke has a special structure with one end larger than the other, the larger end is positioned downward. The quasi-conical smoke then falls onto guide plate 2 and continues to slide down to assembly line b under its own weight. When the quasi-conical smoke reaches guide plate 2, the larger end contacts guide plate 2 first.

[0028] In order to allow the cone-shaped cigarette to roll down on the rolling plate 1 by its own gravity and slide down on the guide plate 2 by its own gravity, the rolling plate 1 and the guide plate 2 are both at a certain angle to the horizontal plane. Specifically, the angle is 20-26 degrees, preferably 24 degrees.

[0029] Specifically, the rolling plate 1 is a smooth flat plate, and the guide plate 2 is provided with a guide groove 3. In order to better adjust the posture of the quasi-conical smoke, the guide groove 3 is a V-shaped groove. If the length of the rolling plate 1 for the quasi-conical smoke to roll down is too short, the posture of the quasi-conical smoke has not yet been adjusted. At this time, the posture of the quasi-conical smoke falling into the V-shaped guide groove 3 of the guide plate 2 is relatively messy, and it is impossible to complete the subsequent posture consistency adjustment; and if it is too long, due to the influence of inertia, the posture of the quasi-conical smoke is excessively adjusted, which also causes the posture of the quasi-conical product falling into the V-shaped guide groove 3 of the guide plate 2 to be relatively messy, affecting the overall feeding efficiency; therefore, the length of the rolling plate 1 for the quasi-conical smoke to roll down is 1.5-2.0 times the length of the quasi-conical smoke; this length can meet the requirement that the quasi-conical smoke entering the rolling plate 1 laterally will be rotated by its own gravity so that its thick end is forward. Similarly, the length of the guide groove 3 for the quasi-conical smoke to slide down should not be too long or too short. If it is too long, the quasi-conical smoke will be affected by friction and eventually stay in the V-shaped guide groove of the guide plate 2, and will not be able to enter the assembly line. If it is too short, the quasi-conical smoke will directly enter the assembly line before the posture of the rolling plate 1 is completely stabilized. Therefore, the length of the guide groove 3 for the quasi-conical smoke to slide down is 1.1-1.6 times the length of the quasi-conical smoke.

[0030] Based on the above technical solutions, such as Figure 2 As shown, the guide mechanism of the present application also includes a fixing portion 4 for fixing the guide mechanism as a whole at the feed end of the assembly line. There are many ways to set the fixing portion. Figure 2 The fixing part 4 is set on both sides of the guide mechanism. When in use, it is fixed at the feed end of the pipeline b (such as Figure 4 As shown), the fixing portion 4 can also be arranged at the bottom of the guide mechanism and fixed to the floor of the workshop.

[0031] After using the above-mentioned guiding mechanism, the conical cigarettes entering the production line will maintain the same posture with the big head facing forward, thereby providing a good foundation for the next step of packaging.

[0032] Example 2

[0033] Based on the guide mechanism in Example 1, the present application provides an assembly line for cone-shaped cigarette packaging, such as Figure 4As shown, the assembly line includes a guide mechanism arranged at the feed end of the assembly line for adjusting the conical smoke entering the assembly line to a posture with the large end facing forward. The guide mechanism is the guide mechanism in Example 1.

[0034] During packaging, the quasi-conical cigarettes are first placed on the rolling plate 1, or lifted onto the rolling plate 1 by a hoist; then, the quasi-conical cigarettes roll down along the rolling plate 1 under the action of their own gravity. During the rolling process, the quasi-conical cigarettes constantly adjust their posture with the big end facing downwards;

[0035] When the quasi-conical smoke leaves the rolling plate 1, the thick end (i.e., the big end) of the quasi-conical smoke moves forward into the guide groove 3 and the guide groove 3 further adjusts the posture of the quasi-conical smoke. Then, the quasi-conical smoke continues to slide downward along the guide groove 3 and finally enters the assembly line.

[0036] When the quasi-conical smoke leaves the rolling plate 1 and enters the guide groove 3, the thick end of the quasi-conical smoke moves forward, but at this time, the quasi-conical smoke is not completely along the direction of the guide groove 3. However, due to the effect of the V-shaped guide groove 3, the posture of the quasi-conical smoke completes the final adjustment, and the big end moves forward and continues to slide along the guide groove 3.

[0037] Each embodiment in this specification is described in a related manner. Similar parts between the embodiments can be referred to in conjunction with each other. Each embodiment focuses on the differences from other embodiments. The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
