Description

Technical Field

[0001] The present invention relates to the technical field of sorting, and in particular to a system and method for improving the efficiency of cigarette carton sorting and packaging. Background Art

[0002] With the continuous development of the tobacco industry, tobacco carton brands have become diversified, with diversified carton sizes and diverse carton materials. At present, the tobacco sorting industry requires the realization of online sorting of all specifications. Under the condition of a certain total number of carton shapes, reducing the number of packages and improving the loading rate and stability of carton cigarettes are the main directions for realizing carton cigarette sorting. Due to the inherent characteristics of the diverse shapes of carton cigarettes, the development direction of sorting equipment is affected. Different shapes and materials of carton cigarettes have a great impact on the packaging in the sorting process. The more special shapes are handled, the more complex the equipment is. As a result, the sorting and packaging equipment becomes more complicated and the number of carton cigarettes is superimposed, which makes the sorting and packaging equipment inefficient and insufficient in production capacity.

[0003] At present, the sorting and packaging equipment on the market mainly adopts the dual-entry mode. The traditional sorting and packaging mode mainly uses the sorting line to store and sort the same type of cigarettes. When the quantity of one type far exceeds that of another type, this mode will lead to a significant reduction in system resource utilization, unbalanced system operating capacity, and mismatch between sorting and packaging. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a system and method for improving the efficiency of cigarette carton sorting and packaging. By constructing data for customer orders, the utilization rate of system resources is improved, and the capacity matching of sorting and packaging is achieved.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a system for improving the efficiency of cigarette sorting and packaging, comprising a first double-entry packaging machine, a first standard cigarette sorting line, a second standard cigarette sorting line and a first non-standard cigarette sorting line, the first standard sorting line is connected to the first inlet of the first double-entry packaging machine, the second standard cigarette sorting line and the first non-standard cigarette sorting line are connected to the second inlet of the first double-entry packaging machine after merging through a first swing arm belt conveyor.

[0006] It also includes a second double-entrance packaging machine, a third standard cigarette sorting line, a second non-standard cigarette sorting line and a third non-standard cigarette sorting line. The second non-standard cigarette sorting line is connected to the second inlet of the second double-entrance packaging machine, and the third standard cigarette sorting line and the third non-standard cigarette sorting line are connected to the first inlet of the second double-entrance packaging machine after merging through a second swing arm belt conveyor.

[0007] The first standard cigarette sorting line, the second standard cigarette sorting line and the third standard cigarette sorting line are connected to the outlet end of the third swing-arm belt conveyor, and the inlet end of the third swing-arm belt conveyor is connected to the standard cigarette input end.

[0008] The second non-standard cigarette sorting line and the third non-standard cigarette sorting line are connected to the outlet end of the fourth swing-arm belt conveyor, the inlet end of the fourth swing-arm belt conveyor is connected to the non-standard cigarette input end, and the first non-standard cigarette sorting line and the third non-standard cigarette sorting line are separated by the fifth swing-arm belt conveyor.

[0009] A method for improving the efficiency of cigarette sorting and packaging, using the above system, is as follows: Analyze the ratio of standard cigarettes to non-standard cigarettes in customer orders. If the ratio of standard cigarettes to non-standard cigarettes is 1 to 1.5, standard cigarettes are fed into the first standard cigarette sorting line in groups of 25 and flow into the first entrance of the first double-entry packaging machine. The remaining quantity less than 25 is fed into the second standard cigarette sorting line and flows into the second entrance of the first double-entry packaging machine and is grouped into 5n pieces, where 1≤n≤4, and n is an integer and takes the maximum value according to the remaining quantity. Finally, standard cigarettes less than 5 pieces are defined as a group; non-standard cigarettes are fed into the first non-standard cigarette sorting line in groups of 20 pieces and flow into the second entrance of the first double-entry packaging machine. The remaining quantity less than 20 pieces is grouped into 4 pieces. Finally, non-standard cigarettes less than 4 pieces are defined as a group; If the ratio of standard cigarettes to non-standard cigarettes exceeds 1.5, 80% of the standard cigarettes enter the first standard cigarette sorting line in groups of 25 and flow into the first entrance of the first double-entry packaging machine. The remaining amount less than 25 enters the second standard cigarette sorting line and flows into the second entrance of the first double-entry packaging machine and is grouped into 5n pieces, where 1≤n≤4, and n is an integer and the maximum value is taken according to the remaining amount. Finally, the standard cigarettes less than 5 pieces are defined as a group; 20% of the standard cigarettes enter the second standard cigarette sorting line in groups of 20 and flow into the second entrance of the first double-entry packaging machine. The remaining amount less than 20 pieces are grouped into 5n pieces, where 1≤n≤3, and n is an integer and the maximum value is taken according to the remaining amount. Finally, the standard cigarettes less than 5 pieces are defined as a group; non-standard cigarettes enter the first non-standard cigarette sorting line in groups of 20 and flow into the second entrance of the first double-entry packaging machine. The remaining amount less than 20 pieces are grouped into 4 pieces. Finally, the non-standard cigarettes less than 4 pieces are defined as a group.

[0010] When the customer order volume meets the packaging efficiency of a single double-entry packaging machine of 10,000 to 30,000 pieces / hour, the above method is adopted. When the customer order volume exceeds the packaging efficiency of a single double-entry packaging machine of 30,000 pieces / hour, the second double-entry packaging machine, the third standard cigarette sorting line, the second non-standard cigarette sorting line and the third non-standard cigarette sorting line are added, and the following method is adopted: A customer's complete full-standard cigarettes are regarded as the excess part. The standard cigarettes in the excess part are fed into the third standard cigarette sorting line in groups of 20 and flow into the first entrance of the second double-entry packaging machine. The remaining amount less than 20 are grouped into 5n groups, where 1≤n≤3, and n is an integer and the maximum value is taken according to the remaining amount. Finally, the standard cigarettes less than 5 are defined as a group. 80% of the non-standard cigarettes in the excess part are fed into the second non-standard cigarette sorting line in groups of 20 and flow into the second entrance of the second double-entry packaging machine. The remaining amount less than 20 are fed into the third non-standard cigarette sorting line and flow into the first entrance of the second double-entry packaging machine and are grouped into 4 groups. Finally, the non-standard cigarettes less than 4 are defined as a group; 20% of the non-standard cigarettes in the excess part are fed into the third non-standard cigarette sorting line in groups of 4 and flow into the first entrance of the second double-entry packaging machine. The non-standard cigarettes less than 4 are defined as a group.

[0011] The standard cigarettes at the first inlet of the first double-inlet packaging machine are placed below the full-standard cigarettes at the second inlet of the first double-inlet packaging machine.

[0012] The full-standard cigarettes at the first inlet of the second double-inlet packaging machine are placed below the non-standard cigarettes at the second inlet of the second double-inlet packaging machine.

[0013] Beneficial effects of the present invention: The present invention realizes parallel combination work by setting up different sorting lines and performing multiple confluences or diversions, and at the same time constructs data for customer orders, and distributes all types of cigarette cartons to different sorting lines according to a regular pattern, thereby reducing the sorting task volume of a single sorting line to meet the packaging efficiency of the packaging machine, thereby achieving sorting and packaging capacity matching, greatly improving sorting and packaging efficiency, enhancing the stability of machine operation, and ensuring a stable packaging stack with standard cigarettes at the bottom and non-standard cigarettes at the top.

[0016] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments. Example

[0017] like Figure 1 to Figure 2 As shown, the present invention provides a system and method for improving the efficiency of cigarette sorting and packaging, wherein a system for improving the efficiency of cigarette sorting and packaging comprises a first double-entry packaging machine 1, a first standard cigarette sorting line 2, a second standard cigarette sorting line 3 and a first non-standard cigarette sorting line 4, wherein the first standard sorting line 2 is connected to the first inlet of the first double-entry packaging machine 1, and the second standard cigarette sorting line 3 and the first non-standard cigarette sorting line 4 are connected to the second inlet of the first double-entry packaging machine 1 after merging through a first swing arm belt conveyor 5.

[0018] Specifically, it also includes a second double-entrance packaging machine 6, a third standard cigarette sorting line 7, a second non-standard cigarette sorting line 8 and a third non-standard cigarette sorting line 9. The second non-standard cigarette sorting line 8 is connected to the second inlet of the second double-entrance packaging machine 6, and the third standard cigarette sorting line 7 and the third non-standard cigarette sorting line 9 are connected to the first inlet of the second double-entrance packaging machine 6 after merging through a second swing arm belt conveyor 10.

[0019] Specifically, the first standard cigarette sorting line 2 , the second standard cigarette sorting line 3 and the third standard cigarette sorting line 4 are connected to the outlet end of the third swing arm belt conveyor 11 , and the inlet end of the third swing arm belt conveyor 11 is connected to the standard cigarette input end 12 .

[0020] Specifically, the second non-standard cigarette sorting line 8 and the third non-standard cigarette sorting line 9 are connected to the outlet end of the fourth swing arm belt conveyor 13, the inlet end of the fourth swing arm belt conveyor 13 is connected to the non-standard cigarette input end 14, and the first non-standard cigarette sorting line 4 and the third non-standard cigarette sorting line 9 are separated by the fifth swing arm belt conveyor 15.

[0021] A method for improving the efficiency of cigarette sorting and packaging, using the above system, is as follows: Analyze the ratio of standard cigarettes to non-standard cigarettes in customer orders. If the ratio of standard cigarettes to non-standard cigarettes is 1 to 1.5, standard cigarettes are fed into the first standard cigarette sorting line 2 in groups of 25 and flow into the first inlet of the first double-entry packaging machine 1. The remaining amount less than 25 is fed into the second standard cigarette sorting line 3 and flows into the second inlet of the first double-entry packaging machine 1 and is grouped into 5n pieces, where 1≤n≤4, and n is an integer and takes the maximum value according to the remaining amount. Finally, standard cigarettes less than 5 pieces are defined as a group; non-standard cigarettes are fed into the first non-standard cigarette sorting line 4 in groups of 20 pieces and flow into the second inlet of the first double-entry packaging machine 1. The remaining amount less than 20 pieces is grouped into 4 pieces. Finally, non-standard cigarettes less than 4 pieces are defined as a group; If the ratio of standard cigarettes to non-standard cigarettes exceeds 1.5, 80% of the standard cigarettes enter the first standard cigarette sorting line 2 in groups of 25 and flow into the first entrance of the first double-entrance packaging machine 1, and the remaining amount less than 25 enters the second standard cigarette sorting line 3 and flows into the second entrance of the first double-entrance packaging machine 1 and is grouped into 5n pieces, wherein 1≤n≤4, and n is an integer and takes the maximum value according to the remaining amount, and finally the standard cigarettes less than 5 pieces are defined as a group; 20% of the standard cigarettes enter the second standard cigarette sorting line 3 in groups of 20 and flow into the second entrance of the first double-entrance packaging machine 1, and the remaining amount less than 20 pieces are grouped into 5n pieces, wherein 1≤n≤3, and n is an integer and takes the maximum value according to the remaining amount, and finally the standard cigarettes less than 5 pieces are defined as a group; the non-standard cigarettes enter the first non-standard cigarette sorting line 4 in groups of 20 and flow into the second entrance of the first double-entrance packaging machine 1, and the remaining amount less than 20 pieces are grouped into 4 pieces, and finally the non-standard cigarettes less than 4 pieces are defined as a group.

[0022] It is worth noting that when the ratio of standard cigarettes to non-standard cigarettes is less than 1, another sorting line and packaging machine are used, which are not described in this embodiment.

[0023] When the customer order volume meets the packaging efficiency of a single double-entry packaging machine of 10,000 to 30,000 pieces / hour, the first method mentioned above is adopted. When the customer order volume exceeds the packaging efficiency of a single double-entry packaging machine of 30,000 pieces / hour, the second double-entry packaging machine 6, the third standard cigarette sorting line 7, the second non-standard cigarette sorting line 8 and the third non-standard cigarette sorting line 9 are added, and the following method is adopted: A complete set of full-standard cigarettes of a customer is regarded as the excess part, and the standard cigarettes in the excess part are fed into the third standard cigarette sorting line 7 into the first entrance of the second double-entrance packaging machine 6 in groups of 20, and the remaining amount less than 20 are grouped into 5n groups, where 1≤n≤3, and n is an integer and the maximum value is taken according to the remaining amount, and finally the standard cigarettes less than 5 are defined as a group, and 80% of the non-standard cigarettes in the excess part are fed into the second non-standard cigarette sorting line 8 into the second entrance of the second double-entrance packaging machine 6 in groups of 20, and the remaining amount less than 20 are fed into the third non-standard cigarette sorting line 9 into the first entrance of the second double-entrance packaging machine 6 in groups of 4, and finally the non-standard cigarettes less than 4 are defined as a group; 20% of the non-standard cigarettes in the excess part are fed into the third non-standard cigarette sorting line 9 into the first entrance of the second double-entrance packaging machine 6 in groups of 4, and the non-standard cigarettes less than 4 are defined as a group.

[0024] It is worth noting that when the customer order volume meets the packaging efficiency of a single double-entry packaging machine of 10,000 pieces per hour, the first method mentioned above is still used.

[0025] The standard cigarettes at the first inlet of the first double-inlet packaging machine 1 are placed below the full-standard cigarettes at the second inlet of the first double-inlet packaging machine 1, and the full-standard cigarettes at the first inlet of the second double-inlet packaging machine 6 are placed below the non-standard cigarettes at the second inlet of the second double-inlet packaging machine 6, thereby ensuring the formation of a stable packaging stack with standard cigarettes at the bottom and non-standard cigarettes at the top.

[0026] For ease of understanding, the efficiency of a single double-entry packaging machine is reduced by 10 times. First, to meet the efficiency of a single double-entry packaging machine, the total number of cigarette cartons is set to 1000 for illustration: If the total number of standard cigarettes is 564 and the total number of non-standard cigarettes is 436, the ratio of standard cigarettes to non-standard cigarettes is between 1 and 1.5, 564 / 25=22 with a remainder of 14, so 25 cigarettes are packaged as a group as standard cigarettes, a total of 22 groups enter the first standard cigarette sorting line 2 and flow into the first entrance of the first double-entry packaging machine 1, and the remaining 14 cigarettes enter the second standard cigarette sorting line 3 and flow into the second entrance of the first double-entry packaging machine 1, and 5n cigarettes are packaged as a group as standard cigarettes, n is 2, then 10 cigarettes are packaged as a group, and the remaining 4 cigarettes are specified as standard cigarette residues and packaged as a group; 436 / 20==21 with a remainder of 16, so non-standard cigarettes are packaged as a group as 20 cigarettes, a total of 21 groups enter the first non-standard cigarette sorting line 4 and flow into the second entrance of the first double-entry packaging machine 1, and the remaining 16 cigarettes are packaged as a group as 4 non-standard cigarettes, a total of 4 groups; If the total number of standard cigarettes is 800 and the total number of non-standard cigarettes is 200, the ratio of standard cigarettes to non-standard cigarettes exceeds 1.5, 800×80%=640, that is, 640 standard cigarettes are packed with 25 standard cigarettes, 640 / 25=25 remainder 15, so a total of 25 groups enter the first standard cigarette sorting line 2 and flow into the first entrance of the first double-entrance packaging machine 1, and the remaining 15 enter the second standard cigarette sorting line 3 and flow into the second entrance of the first double-entrance packaging machine 1, with 5n standard cigarettes packaged into a group, where n is 3, 160 standard cigarettes are packaged into a group with 20 standard cigarettes, 160 / 20=8, so a total of 8 groups enter the second standard cigarette sorting line 3 and flow into the second entrance of the first double-entrance packaging machine 1; non-standard cigarettes are packed into a group with 20 non-standard cigarettes and enter the first non-standard cigarette sorting line 4 and flow into the second entrance of the first double-entrance packaging machine 1.

[0027] Similarly, if the efficiency of a single double-entry packaging machine is reduced by 10 times, when it exceeds the efficiency of a single double-entry packaging machine, a customer's complete full-spec cigarettes are taken as the excess part, and the total number of excess cigarettes is set to 1000 for illustration: If the total number of standard cigarettes is 436 and the total number of non-standard cigarettes is 564, 564×0.8=451.2, then count 451 non-standard cigarettes and pack 20 of them into a group, 451 / 20=22 with a remainder of 11, so a total of 22 groups enter the second non-standard cigarette sorting line 8 and flow into the second entrance of the second double-entry packaging machine 6, and the remaining 11 enter the third non-standard cigarette sorting line 9 and flow into the first entrance of the second double-entry packaging machine 6, with 4 non-standard cigarettes packed into a group, for a total of 2 groups, and the remaining 3 are packed into a group as the remaining non-standard cigarettes, 564-451=113, Therefore, 113 non-standard cigarettes are packaged into a group with 4 non-standard cigarettes, 113 / 4=28 with a remainder of 1, so a total of 28 groups enter the third non-standard cigarette sorting line 9 and flow into the first entrance of the second double-entry packaging machine 6, and the remaining 1 is packaged as a group for the remaining non-standard cigarettes; standard cigarettes are packaged into a group with 20 standard cigarettes, 436 / 20=21 with a remainder of 16, so a total of 21 groups enter the third standard cigarette sorting line 7 and flow into the first entrance of the second double-entry packaging machine 6, and the remaining 16 are packaged into a group with 5n standard cigarettes, where n is 3, and the remaining 1 is specified as the remaining standard cigarette packaged as a group.

[0028] Through the above-mentioned customer order data construction method, the problem of mismatch between sorting and packaging capacity can be effectively solved, the stability of system operation can be improved, and the system sorting and packaging efficiency can be maximized.

[0029] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
