Description

Technical Field

[0001] This application relates to the field of cigarette transportation technology, and more specifically, to an automatic frame-loading control method and device for irregularly shaped cigarette packs. Background Technology

[0002] In the process of raw tobacco storage and handling, the "burlap bale + frame" method has been widely adopted in the tobacco industry as an important loading and transportation mode. The frame dimensions are 1855mm x 1604mm x 1485mm, a size already widely used in the tobacco industry. To facilitate subsequent transportation and handling operations, tobacco companies extensively use burlap sheets to pack tobacco leaves into 40kg bales during the tobacco leaf purchasing stage. In the industrial stage, these bales are then framed in four layers, with four bales per layer, arranged in a 4x4 pattern, with each frame holding 16 bales. The frame's shape is as follows... Figure 1 As shown.

[0003] Because tobacco leaves grow in different parts of the plant, they are divided into upper, middle, and lower leaves. The size of upper leaves is less than or equal to the size of middle leaves, which in turn is less than or equal to the size of lower leaves. In other words, the weight of each upper leaf is less than or equal to the weight of each middle leaf, which is less than or equal to the weight of each lower leaf. Furthermore, when packing with burlap, the leaves from these three parts cannot be mixed together; each bale can only be packed with leaves from one part. This results in inconsistencies in the dimensions of the tobacco bales. Additionally, because burlap-bagged tobacco has a certain degree of flexibility, it is easily deformed. Bales packed at the tobacco company's receiving station may deform during storage in the warehouse; and during transportation by truck, the bales are squeezed together, causing further deformation. This results in inconsistent sizes and shapes of the framed tobacco bales; some bales are within the standard size range, while others exceed it, becoming irregularly shaped bales.

[0004] For non-standard, irregularly shaped cigarette packs, during the framing process, due to excessive bulging in height, it is very easy to only be able to fit 3 layers of 12 packs, resulting in a low loading rate. Furthermore, due to the different length, width, and height dimensions, it is very easy to cause a high rate of pack collapse and pack loss, requiring a lot of manual sorting, resulting in low work efficiency, significant safety hazards, and chaotic on-site management.

[0039] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0040] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0041] This application provides an automatic framing control method and device for irregularly shaped cigarette packs. By identifying the influencing factors in the automatic framing process and obtaining the optimal values ​​of these influencing factors, the automatic framing quality is optimized, achieving automatic, stable, and accurate framing of irregularly shaped cigarette packs. This reduces the complexity of manually setting relevant parameters, improves work efficiency, reduces the difficulty of manually framing the packs, and ensures safety and order.

[0042] like Figure 1 As shown, the frame includes a base plate and vertical sidewalls located on two opposite sides of the base plate. Figure 2 and 3 The automated framing system shown includes left and right shaping mechanisms 1, a stacker, a side shaping mechanism 5, an upper shaping mechanism 8, and frame control components. The left and right shaping mechanisms 1 are located upstream of the stacker, which is equipped with a belt conveyor 3 and a telescopic mechanism 4. The side shaping mechanism 5 is located above the belt conveyor 3. The belt conveyor 3, telescopic mechanism 4, and side shaping mechanism 5 are mounted on the stacker frame 2. The frame control components include a frame lifting frame 10, a frame lifting mechanism 6, a frame conveyor 7, and a frame blocking device 9. The frame lifting mechanism 6, frame conveyor 7, upper shaping mechanism 8, and frame blocking device 9 are mounted on the frame lifting frame 10.

[0043] Figure 2In the process, irregularly shaped cigarette packs are transferred from right to left into the frame. The direction of movement of the irregularly shaped cigarette packs is defined as forward, the opposite direction is defined as backward, and the directions perpendicular to the direction of movement are defined as left and right, respectively. When the frame is inside the frame lift 6, its two side walls are perpendicular to the direction of movement of the irregularly shaped cigarette packs. That is to say, after the irregularly shaped cigarette packs fall into the frame, the front or rear end of the packs rests against the side walls of the frame. The irregularly shaped cigarette packs are first shaped left and right by the left and right shaping mechanism 1. Then, when the irregularly shaped cigarette packs are conveyed to the belt conveyor 3 of the stacker, the belt conveyor 3 transports the irregularly shaped cigarette packs from the rear end to the front end of the stacker. After a photoelectric switch detects that the irregularly shaped cigarette packs have reached the front end of the stacker, the belt conveyor 3 stops running. The frames are conveyed from the frame lifting frame 10 via the frame frame conveyor 7 from the left or right buffer chain conveyor to the frame lifting machine 6. A frame blocking device 9, powered by a cylinder, is installed on the right or left side of the frame lifting machine 6. After it rises to a designated height, it ensures that each frame has a fixed position within the frame lifting machine 6. After a photoelectric sensor detects that the frame has reached its position, the frame frame conveyor 7 stops running after a 0.3-second delay. The frame lifting machine 6 then raises the frames to the upper proximity switch detection position. Subsequently, the telescopic mechanism 4 extends forward, and the irregularly shaped cigarette packs extend forward along with it. When the extension reaches the proximity switch detection position, the extension of the telescopic mechanism 4 stops. The side sorting mechanism 5 moves downward to a predetermined position, and its push plate presses the irregularly shaped cigarette packs forward until they reach the designated position. Then, the telescopic mechanism 4 retracts, and the belt conveyor 3 starts operating. Because the irregularly shaped cigarette packs are blocked by the side sorting mechanism 5, they are neatly arranged in the frame according to a predetermined pattern. Next, the upper sorting mechanism 8 moves downward to compress the irregularly shaped cigarette packs, reducing their expansion rate and height. The entire pressurization process lasts 6 seconds. After the upper sorting mechanism 8 presses down for 6 seconds, the frame lift 6 moves downward to the height of one layer of irregularly shaped cigarette packs. Then, the frame lift 6 stops operating, and while the frame lift 6 descends, the upper sorting mechanism 8 moves upward to its initial position, awaiting the next action. The stacking of the first layer of irregularly shaped cigarette packs is complete.

[0044] The second-layer irregularly shaped cigarette pack stacking process is as follows: The irregularly shaped cigarette packs are first shaped left and right by the left and right shaping mechanism 1. Then, when the irregularly shaped cigarette packs are conveyed to the stacker's belt conveyor 3, the belt conveyor 3 transports the irregularly shaped cigarette packs from the rear end of the stacker to the front end. After the photoelectric switch detects that the irregularly shaped cigarette packs have reached the front end of the stacker, the belt conveyor 3 stops running. The frames are conveyed from the frame lift frame 10 via the frame frame conveyor 7 from the left or right buffer chain conveyor to the frame lift 6. A frame stop device 9, powered by a cylinder, is installed on the right or left side of the frame lift 6, ensuring that each frame has a fixed position within the frame lift 6. After the frame is detected to be in position by a photoelectric sensor, the frame frame conveyor 7 stops running after a 0.3-second delay. The frame lift 6 raises the frame to the upper proximity switch detection position. Subsequently, the telescopic mechanism 4 extends forward, and the irregularly shaped cigarette packs extend forward along with it. When the extension reaches the proximity switch detection position, the extension of the telescopic mechanism 4 stops. The side sorting mechanism 5 moves downward to a predetermined position, and its push plate presses the irregularly shaped cigarette packs forward until they reach the designated position. Then, the telescopic mechanism 4 retracts, and the belt conveyor 3 starts operating. Because the irregularly shaped cigarette packs are blocked by the side sorting mechanism 5, they are neatly arranged in the frame according to a predetermined pattern. Then, the upper sorting mechanism 8 moves downward to compress the irregularly shaped cigarette packs, reducing their expansion rate and height. The entire pressurization process lasts 6 seconds. After the upper sorting mechanism 8 presses down for 6 seconds, the frame lift 6 moves downward to the height of one layer of irregularly shaped cigarette packs. Then, the frame lift 6 stops operating, and while the frame lift 6 descends, the upper sorting mechanism 8 moves upward to its initial position, awaiting the next action. The stacking of the second layer of irregularly shaped cigarette packs is complete.

[0045] The third and fourth layers are stacked in the same way as the second layer.

[0046] After the fourth layer of irregularly shaped cigarette packs is stacked, the frame lift 6 descends to its initial position and stops. The frames are stacked on a simultaneous in-and-out basis. A photoelectric detection sensor is installed at the rear center of the frame conveyor 7. During the unloading process, when the photoelectric detection sensor is empty, an empty frame is allowed to enter. When an empty frame reaches the photoelectric detection sensor, if the cylinder of the frame blocking device 9 has not yet reached its designated position, the frame conveyor 7 stops. It continues until the cylinder of the frame blocking device 9 reaches its designated position, at which point the frame conveyor 7 restarts, preparing for the next stacking operation. This process is repeated for stacking irregularly shaped cigarette packs.

[0047] Preferably, after automatic framing, the stacking pattern in the frame is an isosceles trapezoid to prevent the cigarette packs from falling out of the frame during movement.

[0048] Based on the above-mentioned automatic framing system, such as Figure 4 As shown, the automatic packing control method for irregularly shaped cigarette packs provided in this application includes:

[0049] S410: Identify multiple influencing factors in the automated framing process.

[0050] As an example, several influencing factors include the forward rotation speed of the belt conveyor, the extension length of the belt conveyor, the descent height of each floor of the frame lift, the descent speed of the frame lift, the retraction speed of the telescopic mechanism, the extension speed of the telescopic mechanism, and the distance between the baffle of the side sorting mechanism and the frame.

[0051] Specifically, cigarette packs are manually and randomly unloaded from the cigarette cart and then conveyed to the automatic framing system via a conveyor line. The automatic framing system frames cigarette packs of different sizes and shapes. Within the frames, they are automatically framed in a pattern of 4 packs per layer, stacked in 4 layers, for a total of 16 packs. Because the automatic framing requirement for cigarette packs is 40kg / pack, and there are no strict requirements on their dimensions, the cigarette packs are inconsistent in size, varying in length, height, and shape, including round and square packs. This results in inconsistencies in the center of gravity of each pack. During automatic framing, the packs are stacked unevenly, leading to packs falling off in later layers. Therefore, to achieve automatic framing, it is first necessary to solve the problem of inconsistent pack sizes and center positions caused by inconsistent pack dimensions. To address this issue, this application performs shape shaping on all automatically framed cigarette packs in six dimensions: left and right width (left and right shaping mechanism 1), front and back length (side shaping mechanism 5), and top and bottom height (top shaping mechanism 8). The six-dimensional shaping of the cigarette packs is performed in three different locations. First, the width is shaped to facilitate the entry of four cigarette packs per layer into the frame. Then, the length is shaped to ensure the cigarette packs are neatly stacked within the frame, reducing the rate of pack loss. Finally, the height is shaped (upper shaping mechanism 8) to allow four layers of cigarette packs to be stacked in one frame, reducing the need for three layers. The shaping in each direction also ensures that the center of gravity of each cigarette pack is basically consistent.

[0052] Since the cigarette packs are arranged in a four-pack per layer, and each pack needs to be placed in a different position within the frame, their landing locations are not consistent. As the packs are conveyed forward, the belt conveyor retracts under the action of a telescopic mechanism, automatically loading the four packs into different positions within each layer. The trajectory of the packs within the frame resembles a parabola; the motion is projectile motion, a combination of initial horizontal velocity and free fall under gravity. There is a matching relationship between the forward conveyor speed and the retraction speed of the belt conveyor. The forward conveyor speed (which depends on the extension speed of the telescopic mechanism and the forward rotation speed of the belt conveyor) and the retraction speed (which depends on the retraction speed of the telescopic mechanism and the forward rotation speed of the belt conveyor) are crucial factors affecting the efficiency of the automatic pack loading process.

[0053] The cigarette packs undergo projectile motion during automatic framing. For neat stacking, the height of the free fall is crucial. If the free fall is too high, the center of gravity shifts forward, causing the packs to stand upright during framing, making it impossible to stack subsequent packs and limiting the number of layers per frame to three. Therefore, the descent height of each layer of the frame lift is a significant factor affecting the efficiency of automatic cigarette pack framing.

[0054] Since the positions of the packing frames are fixed, if the belt conveyor extends too far into the frames, the preceding packs of cigarettes will fall out. If the belt conveyor extends too short, the following packs will fall out, affecting the automatic packing efficiency. Therefore, the extension length of the belt conveyor is a crucial factor affecting the automatic packing efficiency.

[0055] When the cigarette packs are automatically loaded into the first layer within the frame, the four packs in the first layer need to be stacked neatly and spread out as much as possible, rather than piled together. If they are piled together, packs will fall apart when the next three layers are stacked. When the cigarette packs are automatically loaded into the second layer within the frame, the four packs in the second layer need to be stacked neatly and spread out as much as possible, rather than piled together. If they are piled together, packs will fall apart when the next two layers are stacked. When the cigarette packs are automatically loaded into the third layer within the frame, the four packs in the third layer need to be stacked neatly, and the four packs should be intentionally moved towards the center of the frame. Therefore, the four layers of cigarette packs stacked within the frame form an isosceles trapezoid shape.

[0056] To achieve good stacking results, the belt conveyor 3, the telescopic mechanism 4, and the frame lifting mechanism 6 are controlled by frequency converters, which makes it easy to adjust the speed of each mechanism and achieve the most reasonable speed matching effect.

[0057] S420: Analyze the impact of multiple influencing factors on the quality of automatic framing.

[0058] As an example, the analytic hierarchy process (AHP) is used to analyze the influence of multiple factors on the quality of automatic framing. The influence of all factors on the quality of automatic framing is denoted as vector A(a1, a2, a3, a4, a5, a6, a7).

[0059] S430: Determine the optimal value of the impact factor based on all impact factors and their corresponding degree of impact.

[0060] As an example, the optimal values ​​of the impact factors are determined based on all impact factors and their corresponding degrees of influence, including:

[0061] S4301: Determine the automatic framing quality score based on different combinations of influence factor values.

[0062] As an example, the automatic framing quality score is determined based on different combinations of influence factor values, specifically including:

[0063] P1: For each combination of values ​​for an influencing factor, obtain an evaluation set consisting of all evaluation results from multiple evaluators on the quality of automatic framing.

[0064] The combination of values ​​is denoted as vector F(f1, f2, f3, f4, f5, f6, f7). As an example, Table 1 shows one of the value combinations, denoted as vector F(50, 320, 1900, 50, 150, 50, 50).

[0065] Table 1

[0066]

[0067]

[0068] It should be noted that for the automatic framing system, each influence factor has a set range, and the value of each influence factor in the value combination cannot exceed the set range.

[0069] Taking the evaluation results as excellent, good, average, and poor as an example, the evaluation set is denoted as vector V(v1, v2, v3, v4). The value of each element in vector V is obtained by converting the above evaluation results into numbers.

[0070] P2: The fuzzy comprehensive evaluation matrix R is formed based on the evaluation set and the corresponding value combinations.

[0071] First, a single-factor fuzzy evaluation is performed, which involves determining the membership degree of each element in the value combination to each element in the evaluation set. All membership degrees are then combined to form the fuzzy comprehensive evaluation matrix R. In the example above, the fuzzy comprehensive evaluation matrix R is a 7*4 matrix.

[0072] P3: Determine the membership degree B of the result based on the fuzzy comprehensive evaluation matrix R and the degree of influence of multiple influencing factors on the quality of automatic framing.

[0073] As an example, the product of vector A and fuzzy comprehensive evaluation matrix R is used as the result membership degree B. Here, the result membership degree B is a 1*4 matrix.

[0074] P4: Calculate the automatic framing quality score Q corresponding to the result membership degree B and the evaluation set and the value combination.

[0075] Specifically, the product of the membership degree B and the grade vector S corresponding to the evaluation set is used as the autoframing quality score Q corresponding to the value combination. Each element in the evaluation set is transformed into a numerical value representing the degree of quality of the autoframing, which serves as the grade corresponding to that element. The grade scores corresponding to all elements in the evaluation set form the grade vector S corresponding to the evaluation set.

[0076] As an example, for the above evaluation results including excellent, good, average, and poor, the grade vector S = (100, 80, 60, 30).

[0077] S4302: The combination of impact factor values ​​corresponding to the highest value of the automatic framing quality score is taken as the optimal value of the impact factor.

[0078] Table 2 provides an example of the optimal value for the influence factor.
