Description
Technical Field
[0001] The utility model relates to the technical field of tobacco logistics sorting and packaging, and further relates to a full-size cigarette stacking device. Background Art
[0002] Tobacco companies gather cigarettes of different specifications together according to customer orders and package them using packaging machines. Existing cigarette carton packaging machines can perform operations such as stacking, packing, and packaging on cigarette cartons.
[0003] Cigarette cartons need to be placed onto the flaps, which are then rotated to drop. If the flaps are too narrow, shorter cartons will fall directly through the gap between the two flaps. To accommodate cartons of all sizes, the flaps must be very wide. If they are too wide, they take up a lot of space when they flip down, causing the cartons to fall too high. This large height difference causes excessive impact on the cartons, making it impossible to drop them stably, affecting their shape and, consequently, the stability of the stack. Therefore, tobacco cartons are generally classified and stacked, and several stacking mechanisms are designed to accommodate different types of cartons.
[0004] The traditional stacking method is to divide cigarette strips into three major categories: standard cigarettes, thin and medium cigarettes, and special cigarettes, and stack them separately through three corresponding stacking mechanisms. The cigarettes from the three stacking mechanisms are then merged together to form a stack of cigarettes.
[0005] For those skilled in the art, how to improve the versatility of the flipping and falling of cigarette cartons is a technical problem that needs to be solved at present. Utility Model Content
[0006] The core of this utility model is to provide a full-size cigarette stacking device. When the sliding flap flips downward, the space occupied is smaller than the width of the flap, which reduces the height of the falling cigarette strips, improves the stability of the fall, and has better versatility. The specific solution is as follows:
[0007] A full-size cigarette stacking device, comprising:
[0008] The flip mechanism is provided with two groups, each comprising a rotator, a sliding flap and a guide frame. The sliding flap is slidably mounted on the output portion of the rotator, and the rotator is used to drive the sliding flap to move. The guide frame is provided with a guide rail, and the sliding flap is provided with a guide block, and the guide block is used to move along the guide rail.
[0009] When the outer edge of the sliding flap rotates downward, the sliding flap slides toward the inner edge relative to the rotator, so that the lowest distance the sliding flap moves downward is less than the width of the sliding flap.
[0010] Optionally, a group of the flipping mechanisms is provided with two or three sliding flaps, which are centrally symmetrically arranged about the rotating axis of the rotator.
[0011] Optionally, a group of the flipping mechanisms is provided with two sliding flaps that are offset and parallel to each other. When the sliding flap is horizontal, the area of the guide rail above the sliding flap is an arc with a first length as a radius, and the radial dimension of the arc of the area of the guide rail below the sliding flap is smaller than the first length.
[0012] Optionally, sliding rods are provided on the two wide sides of the sliding flap for slidingly cooperating with the rotator.
[0013] Optionally, the guide rail is a groove provided on the surface of the guide frame, and the guide block is a rotatable roller.
[0014] Optionally, a first cigarette receiving mechanism is further included, which includes a first cigarette receiving plate and a first lifting drive, wherein the first lifting drive is used to drive the first cigarette receiving plate to perform vertical displacement, and the first cigarette receiving plate is used to receive the cigarettes falling from the sliding flap.
[0015] Optionally, a side push mechanism is further included, which includes a side push plate and a side push driver, wherein the side push driver is used to drive the side push plate to perform lateral displacement, so as to laterally push the cigarette strips placed on the first cigarette receiving plate.
[0016] Optionally, two second cigarette receiving mechanisms are further included above the first cigarette receiving mechanism, each including a second cigarette receiving plate, a second lifting drive and a second translation drive. The second lifting drive and the second translation drive cooperate to enable the second cigarette receiving plate to move up and down and translate.
[0017] Optionally, the second cigarette receiving plate includes a horizontal plate and a vertical plate that are arranged perpendicular to each other.
[0018] Optionally, the horizontal plate of the second cigarette receiving plate and the first cigarette receiving plate are comb plates that are parallel and staggered with each other.
[0019] The utility model provides a full-size cigarette stacking device, which is equipped with two sets of flipping mechanisms. The sliding flap is slidably installed on the output part of the rotator. When the rotator drives the sliding flap to move, the sliding flap can be driven to slide relative to the rotator; a guide block is provided near the outer edge of the sliding flap, and the guide block moves along the guide rail. When the outer edge of the sliding flap is rotated downward, the minimum distance that the sliding flap moves downward is less than the width of the sliding flap, and the sliding flap slides toward the inner edge relative to the rotator. No matter the outer size of the cigarette strips, they can be undertaken by the sliding flap. Since the sliding flap will slide upward for a distance when it is rotated downward, the height of the falling cigarette strips can be reduced, and the stability of the falling cigarette strips is higher. It can be used for both large-sized cigarette strips and small-sized cigarette strips, thereby improving the versatility of the flipping and falling of the cigarette strips.

DETAILED DESCRIPTION
[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the full-size cigarette stacking device of the present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.
[0032] Combine Figure 1 、 Figure 2 As shown, A represents a cigarette carton. The utility model provides a full-size cigarette stacking device, which includes a flipping mechanism 1. The flipping mechanism 1 is provided in two groups, and each group of flipping mechanisms 1 includes a rotator 11, a sliding flap 12, and a guide frame 13. The output portion of the rotator 11 can output rotation. The rotator 11 can be driven by a motor, and its output portion is mounted on the motor shaft, and the output portion can rotate in a circular motion.
[0033] The sliding flap 12 is slidably mounted on the output portion of the rotator 11 . The sliding flap 12 can slide and translate relative to the rotator 11 . The edge of the sliding flap 12 close to the rotator 11 is the inner edge, and the edge away from the rotator 11 is the outer edge.
[0034] When the output part of the rotator 11 rotates, the sliding flap 12 is driven to rotate by the output part of the rotator 11 and also translates relative to the output part of the rotator 11. The movement of the sliding flap 12 is a composite superimposed movement of rotation and translation.
[0035] The guide frame 13 is provided with a guide rail 131, and the sliding flap 12 is provided with a guide block 121. The guide block 121 can be positioned flush with the outer edge or on the side of the sliding flap 12. The guide block 121 protrudes from the sliding flap 12 and is configured to move along the guide rail 131, defining the movement path of the sliding flap 12. The path of the guide rail 131 is an arc, which ensures smooth movement of the sliding flap 12.
[0036] When the outer edge of the sliding flap 12 rotates downward, that is, when the outer edge of the sliding flap 12 is lower than the height of the horizontal position, the guide rail 131 is a closed annular curve structure. The portion of the guide rail 131 located below the horizontal state of the sliding flap 12 is provided with a curve, which can be called the lower curve, and the portion of the guide rail 131 located above the horizontal state of the sliding flap 12 is called the upper curve. The distance (radial dimension) between each point on the lower curve and the rotation axis of the rotator 11 is smaller than the distance between the guide block 121 and the inner edge of the sliding flap 12. A circle with the rotation axis of the rotator 11 as the center and the distance between the guide block 121 and the inner edge of the sliding flap 12 as the radius is located outside the lower curve; when the guide block 121 is located at the outer edge of the sliding flap 12, a circle with the rotation axis of the rotator 11 as the center and the width of the sliding flap 12 as the radius is located outside the lower curve. Because of the structural design of the guide rail 131, when the guide block 121 moves in the lower curve, the sliding flap 12 slides toward the inner edge of the rotator 11, so that the minimum distance that the sliding flap 12 moves downward is less than the width of the sliding flap 12, and the size of the sliding flap 12 occupying the lower area is smaller, less than the width of the sliding flap 12.
[0037] The width of the sliding flap 12 allows it to accommodate the largest size of cigarettes when it is in a horizontal state, so it can accommodate cigarettes of different sizes; when the outer edge of the sliding flap 12 rotates downward, the sliding flap 12 as a whole slides toward the inner edge relative to the rotator, and the space occupied below is smaller. The height distance between the mechanism for catching the falling cigarettes below and the cigarettes is smaller, and the distance between the cigarettes falling downward is smaller, which can improve the stability of the falling cigarettes. Regardless of the size of the cigarettes, they can be received by the sliding flap 12 and fall downward. It can be used for both large and small cigarettes, thereby improving the versatility of the flipping and falling of cigarettes.
[0038] On the basis of the above scheme, in the full-size cigarette stacking device of the present invention, a group of turning mechanisms 1 is provided with two or three sliding flaps 12, and the sliding flaps 12 of the same group of turning mechanisms 1 are arranged symmetrically about the axis of rotation of the rotator 11. Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the two groups of flipping mechanisms 1 are arranged in an axisymmetric distribution, the sliding flaps 12 of the two groups of flipping mechanisms 1 move symmetrically and synchronously, and the sliding flaps 12 of the two groups of flipping mechanisms 1 are matched in pairs; Figure 1 、 Figure 3 When one pair of sliding flaps 12 of the two groups of turnover mechanisms 1 are both horizontal or slightly tilted, a row of cigarettes can be received; Figure 4 、 Figure 5 、 Figure 6As shown, the one-way arrow indicates the moving direction of the sliding flap 12 along the guide rail 131. When a pair of sliding flaps 12 are flipped downward at the same time, the cigarettes placed thereon fall downward.
[0039] Specifically, in the present invention, a set of flipping mechanisms 1 is provided with two sliding flaps 12 that are offset and parallel to each other. The structures shown in the drawings of this application are all illustrated by setting two sliding flaps 12 as an example. When the sliding flap 12 is horizontal, the area of the guide rail 131 above the sliding flap 12 is an arc with a first length as a radius, and the radial dimension of the arc of the area of the guide rail 131 below the sliding flap 12 is less than the first length. The first length is the length from the guide block 121 to the rotating shaft of the rotator 11. When the guide block 121 of the sliding flap 12 moves to the upper curve of the guide rail 131, the sliding flap 12 does not slide relative to the rotator 11, and the sliding flap 12 performs a circular motion.
[0040] A set of turning mechanisms 1 is provided with two sliding flaps 12. After one sliding flap 12 horizontally receives a cigarette carton, it only needs to be rotated 180° to enable the other sliding flap 12 to reach a horizontal position to receive a cigarette carton. When a set of turning mechanisms 1 is provided with three sliding flaps 12, after one sliding flap 12 horizontally receives a cigarette carton, it only needs to be rotated 120° to enable the other sliding flap 12 to reach a horizontal position to receive a cigarette carton.
[0041] Combine Figure 7 As shown, slide rods 122 are provided on the two wide sides of the sliding flap 12 for sliding cooperation with the rotator 11. The slide rods 122 can be provided at a position outside the edge of the sliding flap 12, or they can be provided inside the edge of the sliding flap 12 and on the surface of the sliding flap 12.
[0042] Combine Figure 8 As shown, in another embodiment, the sliding flap 12 itself can be set as a grid structure, with multiple sliding rods arranged side by side, and each sliding rod is respectively slidably matched with the rotator 11.
[0043] In one embodiment, the guide rail 131 is a groove provided on the surface of the guide frame 13, and the guide block 121 is a rotatable roller that can extend into the groove to perform the guiding function. The guide rail 131 can also be a curved rod-shaped structure, and the guide blocks 121 are slip rings sleeved outside the rod.
[0044] On the basis of any of the above technical solutions and their mutual combinations, the full-size cigarette stacking device of the present invention further includes a first cigarette receiving mechanism 2, which includes a first cigarette receiving plate 21 and a first lifting drive 22. The first lifting drive 22 is used to drive the first cigarette receiving plate 21 to perform vertical displacement, and the first cigarette receiving plate 21 is used to receive the cigarette rods dropped from the sliding flap 12. When the first lifting drive 22 drives the first cigarette receiving plate 21 to move upward, it can receive the fallen cigarette rods. As the number of layers of cigarette rods is stacked, the first lifting drive 22 drives the first cigarette receiving plate 21 to gradually descend, and the height of the cigarette rods on the first cigarette receiving plate 21 is continuously stacked. After a certain number of layers are stacked, the cigarette rods on the first cigarette receiving plate 21 are removed.
[0045] Furthermore, the full-size cigarette stacking device of the present invention further includes a side push mechanism 4, which includes a side push plate 41 and a side push driver 42. The side push driver 42 is used to drive the side push plate 41 to move laterally. The side push plate 41 is arranged vertically. When the side push plate 41 moves laterally, it pushes the cigarette strips placed on the first cigarette receiving plate 21 and pushes the cigarette strips out of the first cigarette receiving plate 21. It should be noted that when the side push plate 41 is pushed laterally, the first cigarette receiving plate 21 needs to move downward to the bottom of the side push plate 41.
[0046] Furthermore, the full-size cigarette stacking device of the present invention further includes two second cigarette receiving mechanisms 3 located above the first cigarette receiving mechanism 2. Each second cigarette receiving mechanism 3 includes a second cigarette receiving plate 31, a second lifting drive 32, and a second translation drive 33. The second lifting drive 32 and the second translation drive 33 cooperate to make the second cigarette receiving plate 31 move up and down and move in translation. Figure 3 As shown, the second cigarette receiving plate 31 is installed on the output part of the second translation driver 33, and the fixed part of the second translation driver 33 is installed on the output part of the second lifting driver 32. The second translation driver 33 drives the second cigarette receiving plate 31 to move horizontally, and the second lifting driver 32 drives the second translation driver 33 and the second cigarette receiving plate 31 to move vertically.
[0047] The second cigarette receiving plate 31 includes a horizontal plate and a vertical plate that are perpendicularly arranged to each other. The horizontal plate is used to receive cigarette rods, and the vertical plate is used to laterally limit the position of cigarette rods.
[0048] The horizontal plate of the second cigarette receiving plate 31 and the first cigarette receiving plate 21 are parallel and staggered combing plates, each having a plurality of parallel cantilever rods. The second cigarette receiving plate 31 and the first cigarette receiving plate 21 are staggered up and down to realize the transfer of cigarette strips.
[0049] Figure 3 、 Figure 4 、 Figure 5 、 Figure 6The double-headed arrows indicate the movement directions of the first cigarette receiving mechanism 2, the second cigarette receiving mechanism 3, and the side-pushing mechanism 4. During operation, the sliding flap 12 of the flipping mechanism 1 supports the cigarettes, and the rotator 11 drives the sliding flap 12 to rotate, causing the cigarettes to fall and be received by the second cigarette receiving plate 31. The first cigarette receiving plate 21 then rises, and the comb teeth of the first cigarette receiving plate 21 pass upward through the comb teeth of the second cigarette receiving plate 31, supporting the cigarettes. The second cigarette receiving plates 31 on the left and right sides then separate, and the first cigarette receiving plate 21 drives the cigarettes downward. Because the first cigarette receiving plate 21 has a higher vertical displacement height, it can receive more layers of cigarettes. As the first cigarette receiving plate 21 continues to descend, it can directly receive more cigarettes dropped from the sliding flap 12. When the cigarettes received by the first cigarette receiving plate 21 reach the set height, the side-pushing plate 41 pushes the cigarettes out laterally.
[0050] During the process of the side push plate 41 pushing the cigarette carton horizontally, the second cigarette receiving plates 31 on the left and right sides move closer together and can continue to receive the cigarette carton dropped by the sliding flip plate 12, so that the process of the cigarette carton falling downward is continuous and uninterrupted. When the side push plate 41 pushes the cigarette carton, the flip mechanism 1 continues to operate.
[0051] To sum up, since the flaps must be compatible with all sizes of cigarette strips, if the flaps are too narrow, shorter cigarette strips will fall directly from the gap between the two flaps. Therefore, traditional flaps must be made very wide. If the flaps are too wide, they will take up a lot of space when flipping down, resulting in a very high height of the cigarette strips, affecting the posture of the cigarette strips after falling, and thus affecting the stability of the stacks. Therefore, cigarette strips are generally classified and stacked, and several stacking mechanisms are designed to suit different types of cigarette strips.
[0052] The principle of the full-size cigarette stacking device of this utility model is to make the flap movable. When the flap receives cigarettes, the flap is very wide, and the gap between the left and right flaps is very narrow; when the flap flips down, it will slide back to the inner edge. Guide blocks (cam rods and bearings) are installed on the side of the flap to make its trajectory run along the guide rail. When the flap passes the lowest point and then extends again until it becomes horizontal again, the flap is fully extended and begins to receive the next layer of cigarettes. At this time, the cigarette receiving comb plate descends, and the flap continues to flip, and the second layer falls onto the first layer of cigarettes.
[0053] The second cigarette receiving plate 31 and the first cigarette receiving plate 21 operate alternately, so that the turnover mechanism 1 is always in operation, greatly improving the efficiency of stacking cigarettes. Without the assistance of the second cigarette receiving plate 31, after stacking a stack of cigarettes, the first cigarette receiving plate 21 must wait for the stack of cigarettes to be transferred from the first cigarette receiving plate 21 to the next station before the first cigarette receiving plate 21 can be extended and returned to the cigarette receiving station before the next round of stacking cigarettes can be carried out. This process requires the turnover mechanism to wait for at least 2 seconds. The present invention uses the second cigarette receiving plate 31 to assist in temporarily receiving cigarettes, thereby ensuring continuous and uninterrupted transportation of cigarettes.
[0054] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
