Technical Field

[0002] Since traditional plastic cups are difficult to degrade in the natural environment, long-term accumulation will cause serious "white pollution".

[0015] Figure 2 It is a module flow chart of the control method of plastic cup production equipment. DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 2 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0017] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0018] The present application embodiment discloses a method for controlling a plastic cup production device, referring to Figure 1 The method flow of the plastic cup production equipment control method includes the following steps: Step S100: Obtain a production schedule for plastic cups and the production capacity of each production line.

[0019] The production plan is a table that records the number of plastic cups that need to be produced in each time period, which is formulated by the production management personnel. Each time period is one hour. For example, the data recorded in the production plan from 11:00 to 12:00 is 24,000 cups. The production capacity is the maximum number of plastic cups that the production line can produce in a unit time period. The production capacity of each production line is entered in advance by the management personnel.

[0020] Step S101: Determine the production plan quantity for each time period in the production plan table.

[0021] The production plan quantity is the quantity of plastic cups that need to be produced in each time period after the current time period filled in by the manager in the production plan table.

[0022] Step S102: randomly selecting any number of production lines to form a single operation combination, and performing a sum calculation based on all production capacity quantities corresponding to the single operation combination to determine the combined capacity quantity.

[0023] The single operation combination is a combination formed by randomly selected production lines. The combined capacity quantity is the total number of plastic cups that can be produced by the production lines within the single operation combination in a unit time period, which is determined by summing up the corresponding production capacity quantities.

[0024] Step S103: After randomly excluding a production line from the single operation combination, the production capacity quantities of the remaining production lines are summed up to determine the inferior capacity quantity.

[0025] The secondary production capacity is the sum of the production capacities of the remaining production lines that can be obtained after excluding any production line in the single operation combination.

[0026] Step S104: Define a single operation combination whose combined capacity quantity is not less than the production plan quantity and whose all inferior capacity quantities are less than the production plan quantity as a valid operation combination.

[0027] When the combined capacity quantity is not less than the production plan quantity and all inferior capacity quantities are less than the production plan quantity, it means that the currently determined single operation combination is an operation combination that can just produce plastic cups in this time period. At this time, it is defined as a valid operation combination to distinguish different single operation combinations, which is convenient for subsequent analysis.

[0028] Step S105: randomly selecting a valid operation combination in each time period to form an overall production combination, and determining the duration of continuous operation according to each production line in the overall production combination.

[0029] Selecting the corresponding effective operation combination in each time period can constitute an overall production combination for perfectly implementing the production plan in the production schedule. At this time, the overall production combination can be used to determine the specific conditions of the operation of each production line; among them, the continuous operation duration is the maximum continuous operation duration that a single production line will reach during the operation process. The specific determination method can refer to steps S400-S405.

[0030] Step S106: Define the entire production combination in which no production line has a continuous operation duration greater than the preset load operation duration as a valid production combination, select a unique production combination from the valid production combinations, and control each production line to operate according to the production combination.

[0031] The load operation duration is the minimum continuous operation duration set by the staff to determine that the continuous operation of the production line is prone to equipment damage. When there is no continuous operation duration of any production line that is greater than the load operation duration, it means that each production line can operate well under the current overall production combination. At this time, it is defined as a valid production combination to distinguish different overall production combinations. By selecting a production combination from the valid production combinations, the subsequent operation of the production line can be specifically controlled, which is convenient for the production of plastic cups. The method for determining the production combination to be used can be random selection, or it can be determined by referring to the method of steps S500-S602.

[0032] After the production plan quantity is determined, the plastic cup production equipment control method also includes: Step S200: performing a sum calculation based on all production capacity quantities to determine the full load capacity quantity.

[0033] The full-load capacity is the maximum number of plastic cups that can be produced when all production lines are operating simultaneously, and is obtained by adding together all production capacity quantities.

[0034] Step S201: Determine whether the production plan quantity is greater than the full load capacity quantity.

[0035] The purpose of the judgment is to find out whether there is any erroneous input in the currently acquired production plan quantity to affect the normal production of plastic cups.

[0036] Step S2011: If the production plan quantity is not greater than the full-load capacity quantity, the currently determined production plan quantity is maintained.

[0037] When the production plan quantity is not greater than the full-load capacity quantity, it indicates that the possibility of incorrect input is low, and subsequent processing can be carried out normally.

[0038] Step S2012: If the production plan quantity is greater than the full-load capacity quantity, an abnormal identification signal is output and the current production plan quantity is marked.

[0039] When the production plan quantity is greater than the full-load capacity quantity, it indicates that the staff has input the data incorrectly. At this time, an abnormal identification signal is output to identify the situation for further analysis. The incorrect input usually means that a single digit is entered incorrectly. For example, the original quantity is 24,000, but the incorrectly entered quantity is 124,000.

[0040] After the abnormal identification signal is output, the plastic cup production equipment control method further includes: Step S300: Generate a planned quantity range according to the remaining production plan quantities.

[0041] The planned quantity range is the range consisting of the largest planned production quantity and the smallest planned production quantity among the remaining planned production quantities as endpoints.

[0042] Step S301: The production plan quantity when the abnormal identification signal is output is defined as the wrong plan quantity.

[0043] Define the error plan quantity to distinguish different production plan quantities for subsequent analysis.

[0044] Step S302: Randomly delete a digit from the numerical value corresponding to the number of erroneous plans to obtain a simulated update number.

[0045] The simulated update quantity is the value obtained by randomly deleting a digit from the value of the erroneous plan quantity. For example, if the original erroneous plan quantity is 124,000, the simulated update numbers that can be obtained are 24,000, 14,000, 12,000, and 12,400 respectively.

[0046] Step S303: defining the simulated update quantity within the planned quantity range as the effective update quantity, and outputting the effective update quantity to a preset replacement selection system.

[0047] The effective update quantity is defined to identify the simulated update quantity that may be the actual planned quantity, so as to output it to the replacement selection system for selection by the management personnel, wherein the replacement selection system is a system for the management personnel to process data of the production schedule.

[0048] The steps to determine the duration of each production line in the overall production portfolio include: Step S400: Obtain the overall operation status of each production line at the current time point.

[0049] The overall operation status is the operation status of the production line, including the start operation status and the shutdown operation status. The two states indicate whether the production line is operating or not.

[0050] Step S401: define a production line whose overall operation status is consistent with a preset start-up operation status as a used production line.

[0051] The start-up operation state refers to the state when the production line is in operation. The use production line is defined to identify the production line that may be in continuous use, which is convenient for subsequent analysis.

[0052] Step S402: constructing a historical interval with the current time point as the rear end point and a width of the preset historical duration on the preset time axis according to the use of the production line.

[0053] The time axis is a coordinate axis formed by the combination of various time points. The time axis points from the time points that have been reached to the time points that have not yet been reached. The time points that have been reached are on the left side of the time axis, and the left side is defined as the front end of the time axis. The historical duration is the duration set by the staff to obtain data on the historical usage of each production line. By constructing historical intervals, it is convenient to obtain and analyze data within the historical duration.

[0054] Step S403: In the historical interval, the current time point is used as the starting point and the time axis is extended forward to obtain the overall operation status in real time, until the overall operation status is consistent with the preset closing operation status, and the corresponding time point is defined as the starting point.

[0055] The shutdown operation state is the state when the production line is not in use. When the overall operation state is consistent with the shutdown operation state, it is defined as the starting point. At this time, it means that the production line has been used from the starting point until the current time point, which is convenient for subsequent analysis.

[0056] Step S404: construct an identification interval according to the starting point and the corresponding time period in the overall production combination, and determine the continuous operation duration in the identification interval according to the time point when the continuous and uninterrupted overall operation state is the start operation state.

[0057] The identification interval is the time interval between the starting point and the end point after the last time period, and the continuous operation time is the time length that the production line is always in the startup operation state.

[0058] Step S405: determining the continuous operation duration with the largest value according to a preset sorting rule, and determining the continuous operation duration as the continuous operation duration.

[0059] The sorting rule is a method set by the staff to sort the size of the values, such as the bubble method. The sorting rule can be used to determine the continuous operation time with the largest value. At this time, it can be determined as the continuous operation time to realize subsequent analysis of the production line.

[0060] The steps to select a unique production combination from the available production combinations include: Step S500: In the effective production combination, the effective operation combination in the front time period of the adjacent time periods is defined as the preceding operation combination, and the effective operation combination in the rear time period is defined as the succeeding operation combination.

[0061] Defining the preceding and succeeding job combinations can distinguish different valid job combinations, which is convenient for subsequent analysis.

[0062] Step S501: In the subsequent operation combination, the production line in the previous operation combination is defined as a continued production line, and the remaining production lines are defined as new production lines.

[0063] Defining continued production lines and newly opened production lines can distinguish the continuous operation status of each production line, which is convenient for subsequent analysis.

[0064] Step S502: Counting is performed according to the continued production line to determine the continued quantity, and counting is performed according to the newly opened production line to determine the newly opened quantity.

[0065] The continued quantity is the total number of continued production lines determined in a single time period, and the newly opened quantity is the total number of newly opened production lines determined in a single time period.

[0066] Step S503: performing calculations based on the number of continuations and the number of new openings to determine the conversion suitability, and performing average calculations based on all conversion suitabilities to determine the average suitability.

[0067] The conversion suitability reflects the degree of suitability of the production line operation change. The larger the value, the more suitable the production line change is. The calculation formula of the conversion suitability is: ,in To convert the fitness, For the newly opened quantity, To continue the quantity, and is a fixed parameter used in the calculation; the mean fitness is the average of all transformed fitnesses.

[0068] Step S504: Determine the mean fitness with the largest value according to the sorting rule, and determine the effective production combination corresponding to the mean fitness as the production combination to be used.

[0069] The sorting rules can be used to determine the mean fitness with the largest value. At this time, the effective production combination corresponding to the mean fitness is determined as the production combination to be used so that each production line can operate as continuously as possible without exceeding the load operation time, so as to reduce the frequent switching of each production line.

[0070] After the mean suitability is determined, the plastic cup production equipment control method further includes: Step S600: Determine whether there are at least two effective production combinations with the same and maximum mean fitness.

[0071] The purpose of judgment is to find out whether there are multiple effective production combinations that meet the requirements, so as to facilitate subsequent analysis.

[0072] Step S6001: If there are not at least two valid production combinations with the same and maximum mean fitness, the valid production combination with the maximum mean fitness is determined as the production combination to be used.

[0073] When there are not at least two effective production combinations with the same and maximum mean fitness, it means that there is only one effective production combination that meets the requirements. In this case, it can be determined as the production combination to be used.

[0074] Step S6002: If there are at least two effective production combinations with the same and maximum mean fitness, the effective production combination with the maximum mean fitness is defined as the alternative production combination.

[0075] When there are at least two effective production combinations with the same and maximum mean fitness, it means that there are multiple effective production combinations that meet the requirements. At this time, they are defined as alternative production combinations to distinguish different effective production combinations, so as to facilitate the subsequent determination of the only production combination to be used.

[0076] Step S601: determining the number of consecutive continuation times in the candidate production combination according to the continuation production lines determined in each time period.

[0077] The continuous continuation times are the times that the continuation production line is used continuously, which can be determined by the time period that the production line has passed through. Every time a time period has passed, the corresponding continuous continuation times are increased by one.

[0078] Step S602: Calculate the average of all consecutive continuation times to determine the average continuation times, and determine the alternative production combination corresponding to the average continuation times with the largest value as the used production combination.

[0079] The mean continuation times is the average of all continuous continuation times. The larger the value is, the higher the proportion of each production line being used continuously and not switched frequently, and the operating effect of each production line is better. At this time, the alternative production combination corresponding to the largest mean continuation times can be determined as the production combination to be used.

[0080] The steps to control the operation of each production line using the production combination include: Step S700: Calculate the production capacity of the production line of each valid operation combination in the production combination to determine the production proportion.

[0081] The production share is the share of the production capacity of a single production line in all production lines of the effective operation combination, which is determined by dividing the production capacity of a single production line by the sum of the production capacity of all production lines in the effective operation combination.

[0082] Step S701: Calculate the actual production quantity based on the production ratio and the production plan quantity for the corresponding time period.

[0083] The actual production quantity is the number of plastic cups that the production line actually needs to produce in the current time period, which is determined by multiplying the production proportion by the production plan quantity.

[0084] Step S702: Calculate the operation efficiency value based on the actual production quantity and the corresponding production capacity quantity.

[0085] The operating efficiency value is the production efficiency of the production line, which is determined by dividing the actual production quantity by the production capacity quantity.

[0086] Step S703: determining the actual operation parameters corresponding to the operation efficiency values ​​according to the preset parameter matching relationship, and controlling the production line to operate according to the actual operation parameters.

[0087] The actual operating parameters are the parameters of each production equipment when the production line can operate at the production efficiency of the operating efficiency value. The operating parameters of the production equipment are different under different operating efficiency values, so the corresponding actual operating parameters are different. The parameter matching relationship between the two is determined by the staff through multiple tests in advance, which will not be elaborated here; by controlling each equipment on the production line to operate with the actual operating parameters, the entire production line can produce plastic cups at the actual production quantity.
