Description

Technical Field

[0001] This application relates to the field of plastic cup production technology, and in particular to a printing management method and system based on plastic cup production. Background Technology

[0002] Currently, the trend of personalized customization is driving the plastic cup manufacturing industry to transform towards a model of small-batch, multi-variety, and fast delivery. Customized plastic cup manufacturers typically need to complete a large number of printing tasks with different patterns in a short period of time, such as brand promotional cups, commemorative cups, and personalized gift cups. Orders are characterized by large differences in patterns, multiple batches, and short delivery cycles.

[0003] In existing production processes, a "one-to-many" production line layout is commonly used: a main production line continuously outputs unpatterned plastic cup blanks, which are then transported in batches to multiple parallel independent printing production lines through a material distribution system. Each printing production line is responsible for completing the printing task of a specific pattern, and the printing tasks of each production line are generally determined based on their respective printing efficiencies in order to maximize overall output efficiency.

[0004] The printing time varies for different patterns. Therefore, when switching printing tasks, a single production line needs to adjust the feeding timing of the plastic cup preforms (the time interval required for printing two consecutive plastic cup preforms). However, the above solution only considers printing efficiency when allocating tasks, which may result in a single production line frequently adjusting the feeding timing or making large adjustments to the feeding timing in a short period of time. This will put a large production load on the production line and may easily lead to equipment damage. There is still room for improvement. Summary of the Invention

[0005] To reduce the possibility of damage to the production line due to adjustments in material feeding timing, this application provides a printing management method and system based on plastic cup production.

[0006] Firstly, this application provides a printing management method based on the production of plastic cups, employing the following technical solution: A printing management method based on plastic cup production includes: Obtain production orders, which include the required printing pattern, the required printing quantity, and the maximum completion time. Analyze the printing pattern to determine the required printing time; On the preset production line, production orders are randomly allocated and sorted according to demand to determine the individual printing scheme of each production line, and all individual printing schemes are combined to determine the simulated allocation scheme. The order completion time for each production order is determined based on the individual printing plan and the printing demand duration. The simulated allocation plan in which the completion time of each order is less than the limit completion time is defined as the effective allocation plan. Under an effective allocation scheme, the equipment load is adjusted based on the printing time requirements of adjacent tasks in each individual printing scheme. The load is calculated based on the equipment adjustment load to determine the scheme execution load, and the effective allocation scheme corresponding to the minimum scheme execution load is defined as the usage allocation scheme. The plastic cup preform feeding and printing operation is carried out according to the usage allocation scheme.

[0007] The steps involved in analyzing the required printing pattern to determine the required printing time include: The partial printing pattern is determined based on the required printing pattern, and the printing point coordinates of each location are determined based on the partial printing pattern. The horizontal width of the print is determined on the preset horizontal coordinate axis based on the coordinates of the print points, and the vertical width of the print is determined on the preset vertical coordinate axis. The equivalent printing area is determined by calculating the horizontal and vertical widths of the print. The required printing time is determined by calculating the equivalent printing area and the preset equipment printing speed.

[0008] Under an effective allocation scheme, the steps for determining equipment load adjustment based on the printing time requirements of adjacent tasks in each individual printing scheme include: The difference in printing time between adjacent tasks is calculated to determine the feed adjustment time; The adjacent adjustment load corresponding to the feeding adjustment time is determined according to the preset adjustment matching relationship; Within the effective allocation scheme, determine the single-line printing duration and the number of demand adjustments based on the printing scheme of each individual unit, and determine the frequency of load adjustment based on the single-line printing duration and the number of demand adjustments. The device adjustment load is determined by calculating based on all adjacent adjustment loads and frequency adjustment loads.

[0009] After the frequency adjustment load is determined, the printing management method based on plastic cup production also includes: The local printing time is determined by calculating the number of each task and the corresponding printing time requirements. The load is adjusted rapidly according to the preset rapid matching relationship to determine the corresponding rapid printing time of the local area; The frequency-adjusted load is adjusted and updated based on calculations performed using both rapid and frequency-adjusted loads.

[0010] After the execution load of the solution is determined, the printing management method based on plastic cup production also includes: Determine whether the minimum execution load of the solution is less than the preset required execution load; If the minimum execution load of the scheme is not less than the required execution load, then the effective allocation scheme corresponding to the minimum execution load of the scheme is defined as the allocation scheme to be used. If the minimum execution load of the scheme is less than the required execution load, then the effective allocation scheme corresponding to the execution load of the scheme that is less than the required execution load is defined as the alternative allocation scheme. The batch printing time is determined by analyzing the single-line printing time among the alternative allocation schemes; The alternative selection coefficient is determined based on the batch printing time and the execution load of the scheme, and the alternative allocation scheme corresponding to the largest alternative selection coefficient is defined as the allocation scheme to be used.

[0011] After the alternative selection coefficients are determined, the printing management method based on plastic cup production also includes: Determine whether there exist at least two alternative allocation schemes with the same and largest selection coefficients; If there are no at least two alternative allocation schemes with the same and largest alternative selection coefficient, then the alternative allocation scheme corresponding to the largest alternative selection coefficient is defined as the allocation scheme to be used. If there are at least two alternative allocation schemes with the same and largest selection coefficient, then the alternative allocation scheme corresponding to the largest selection coefficient is defined as the backup allocation scheme. Under the alternative allocation scheme, the average load of adjacent adjustment is calculated based on the printing scheme of each individual unit to determine the adjacent average load; The load concentration level is determined by calculating the adjacent average load and each adjacent adjusted load, and the alternative allocation scheme corresponding to the largest load concentration level is defined as the allocation scheme to be used.

[0012] The steps for feeding and printing plastic cup preforms according to the distribution scheme include: Obtain equipment wear values; The equipment health order is determined by sorting the equipment wear values ​​from smallest to largest. Plastic cup preform feeding and printing operations are performed on each production line according to the equipment health sequence and equipment load adjustment in conjunction with the allocation scheme.

[0013] Secondly, this application provides a printing management system based on plastic cup production, which adopts the following technical solution: A printing management system based on plastic cup production includes: The acquisition module is used to acquire production orders, which include the required printing pattern, the required printing quantity, and the maximum completion time. The processing module, connected to the acquisition module, is used for information storage and processing; The processing module analyzes the required printing pattern to determine the required printing time. The processing module randomly allocates and sorts the individual printing schemes for each production line according to the production orders on the preset production line, and combines all the individual printing schemes to determine the simulated allocation scheme. The processing module determines the order completion time of each production order based on the individual printing plan and the printing demand duration, and defines the simulated allocation plan where the completion time of each order is less than the limit completion time as the effective allocation plan. Under the effective allocation scheme, the processing module determines the equipment load adjustment based on the printing demand duration of adjacent tasks in each individual printing scheme; The processing module calculates the load based on the equipment load adjustment to determine the execution load of the scheme, defines the effective allocation scheme corresponding to the minimum execution load as the usage allocation scheme, and performs the plastic cup preform feeding and printing operation according to the usage allocation scheme.

[0014] In summary, this application includes at least one of the following beneficial technical effects: During the plastic cup production and printing process, the specific details of the required printing pattern can be analyzed to rationally allocate printing tasks, thereby reducing the occurrence of frequent and significant adjustments to the feeding timing on a single production line, and thus reducing the possibility of equipment damage. During the production task allocation analysis, the magnitude, frequency, and urgency of the material feeding timing adjustment are comprehensively analyzed to achieve accuracy in determining the material feeding timing.

[0016] Figure 2 This is a module flowchart of the printing management method based on the production of plastic cups. Detailed Implementation

[0017] To make the purpose, technical solution, and advantages of this application clearer, the following is combined with Figures 1-2 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0018] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0019] This application discloses a printing management method based on the production of plastic cups, referring to... Figure 1The method flow for printing management based on plastic cup production includes the following steps: Step S100: Obtain the production order, which includes the required printing pattern, the required printing quantity, and the maximum completion time.

[0020] The production order demand refers to the plastic cup production order that needs to be completed under the current production batch. Data can be directly obtained by connecting to an external data interface. The printing pattern demand refers to the pattern that needs to be printed on the surface of the plastic cup. The printing quantity demand refers to the number of plastic cups that need to be produced. The maximum completion time is the maximum allowable completion and delivery time.

[0021] Step S101: Analyze the required printing pattern to determine the required printing time.

[0022] The printing time requirement is the time required for the printing equipment to print the current printed pattern. For specific determination methods, please refer to steps S200-S203.

[0023] Step S102: Randomly allocate and sort the production orders according to their needs on the preset production line to determine the individual printing scheme for each production line, and combine all the individual printing schemes to determine the simulated allocation scheme.

[0024] This production line is the "many" production line in the "one-to-many" production line, that is, the production line used to receive plastic cup blanks for printing. Different simulated production schemes, namely single-unit printing schemes, can be constructed by randomly allocating and sorting the demand production orders. The task of a single demand production order can be assigned to different production lines. Therefore, the task allocation is based on the processing quantity, and random sorting can simulate different processing and production sequences for subsequent analysis. The simulated allocation scheme is the production scheme formed by combining the single-unit printing schemes of all production lines, that is, the production processing scheme that can complete the demand production order of the current batch.

[0025] Step S103: Determine the order completion time of each production order based on the individual printing plan and printing demand duration, and define the simulated allocation plan where the completion time of each order is less than the limit completion time as the effective allocation plan.

[0026] Order completion time refers to the latest time for a single production order of plastic cups to be completed. The completion time of each type of plastic cup on each production line can be determined by the printing scheme and the printing demand time. At this time, the latest completion time of a single type of plastic cup is the order completion time. When the order completion time is less than the limit completion time, it means that the production scheme at this time meets the requirements from the delivery perspective. Therefore, an effective allocation scheme is defined to identify and distinguish different simulated allocation schemes for subsequent analysis.

[0027] Step S104: Under the effective allocation scheme, determine the equipment load adjustment based on the printing demand duration of adjacent tasks in each individual printing scheme.

[0028] The equipment adjustment load refers to the load generated by the feeding timing required for different types of plastic cups. For example, if the printing time for type A plastic cups is 3 seconds, then the feeding interval between two plastic cups is 3 seconds to ensure continuous feeding. After the production of type A plastic cups is completed, the process switches to type B plastic cups, which have a printing time of 4 seconds. Therefore, the feeding interval of the plastic cups needs to be adjusted to 4 seconds. The load generated by adjusting the equipment structure when adjusting from 3 seconds to 4 seconds is the equipment adjustment load. This load can be determined by calculating the difference between the printing time requirements of two different tasks. The larger the difference, the larger the corresponding equipment adjustment load. Alternatively, the equipment adjustment load can be determined using the methods in steps S300-S303.

[0029] Step S105: Calculate the load to determine the scheme execution load based on the equipment load adjustment, define the effective allocation scheme corresponding to the minimum scheme execution load as the usage allocation scheme, and perform plastic cup preform feeding and printing operations according to the usage allocation scheme.

[0030] The scheme execution load is the average value of the load adjustment of all equipment. The minimum scheme execution load indicates that the corresponding production line is performing best when in use. Therefore, it is defined as the use allocation scheme for identification and differentiation, thereby controlling the feeding operation of the corresponding plastic cup preforms. This meets production requirements and avoids situations where a single production line frequently adjusts or significantly adjusts the feeding timing, thereby reducing the possibility of production line damage and improving the overall effect of plastic cup production and printing.

[0031] The steps involved in analyzing the required printing pattern to determine the required printing time include: Step S200: Determine the partial printing pattern according to the required printing pattern, and determine the printing point coordinates of each location point according to the partial printing pattern.

[0032] A partial printing pattern is an independent pattern on the required printing pattern. It can be determined by connecting the feature points on each pattern. The printing point coordinates are the coordinate values ​​relative to the Cartesian coordinate system constructed by the printing equipment, including the X-axis coordinates and the Y-axis coordinates.

[0033] Step S201: Determine the horizontal width of printing on the preset horizontal coordinate axis based on the coordinates of the printing points, and determine the vertical width of printing on the preset vertical coordinate axis.

[0034] The horizontal axis is the X-axis. The horizontal width of the printing is the distance between the point with the smallest value and the point with the largest value on the horizontal axis. In other words, it is the distance that the printing equipment brush head needs to move on the horizontal axis. Similarly, the vertical axis is the Y-axis. The vertical width of the printing is the distance between the point with the smallest value and the point with the largest value on the vertical axis. In other words, it is the distance that the printing equipment brush head needs to move on the vertical axis.

[0035] Step S202: Calculate the equivalent printing area based on the printing horizontal width and printing vertical width.

[0036] The equivalent printing area is the area of ​​the pattern that needs to be processed for printing under theoretical conditions, and it is determined by multiplying the horizontal printing width by the vertical printing width.

[0037] Step S203: Calculate the required printing time based on the equivalent printing area and the preset equipment printing speed.

[0038] The printing speed is the printing speed that the staff inputs in advance based on the operating capacity of each printing machine. The printing time can be determined by dividing the equivalent printing area by the printing speed.

[0039] Under an effective allocation scheme, the steps for determining equipment load adjustment based on the printing time requirements of adjacent tasks in each individual printing scheme include: Step S300: Calculate the difference between the printing demand duration of adjacent tasks to determine the feeding adjustment duration.

[0040] The feeding adjustment time is the difference between the printing demand time of adjacent tasks. This difference is an absolute value. Taking the example in step S104 above, the feeding adjustment time is 1 second.

[0041] Step S301: Determine the adjacent adjustment load corresponding to the feeding adjustment time according to the preset adjustment matching relationship.

[0042] The adjacent adjustment load refers to the load that the printing equipment will bear when the feeding timing is adjusted. The longer the feeding adjustment time, the greater the corresponding adjacent adjustment load. The adjustment matching relationship between the two is determined by the staff in advance through multiple tests.

[0043] Step S302: Within the effective allocation scheme, determine the single-line printing duration and the number of adjustment requests based on the printing scheme of each individual unit, and determine the frequency adjustment load based on the single-line printing duration and the number of adjustment requests.

[0044] The single-line printing time is the total time required for a single production line to execute a single printing plan. It can be determined by analyzing the specific printing task. The number of demand adjustments is the number of times the feeding timing needs to be adjusted. The frequency adjustment load is a value reflecting the equipment load from the adjustment frequency. It is determined by dividing the number of demand adjustments by the single-line printing time and multiplying by a preset dimension adjustment parameter. This dimension adjustment parameter is set by the staff according to the actual situation.

[0045] Step S303: Calculate and determine the device adjustment load based on all adjacent adjustment loads and frequency adjustment loads.

[0046] The device adjustment load can be determined by adding the average of all adjacent adjustment loads to the frequency adjustment load.

[0047] After the frequency adjustment load is determined, the printing management method based on plastic cup production also includes: Step S400: Calculate the local printing time based on the quantity of each task and the corresponding printing time requirement.

[0048] The local printing time is the production time required for a single type of plastic cup on a single production line, and is determined by multiplying the quantity of that type of plastic cup by the corresponding printing time requirement.

[0049] Step S401: Determine the load adjustment corresponding to the local printing duration based on the preset rapid matching relationship.

[0050] The urgent adjustment load reflects the load value generated when the feeding timing is adjusted urgently. The shorter the local printing time, the more urgent the need for a second adjustment of the feeding timing, and therefore the greater the corresponding urgent adjustment load. The urgent matching relationship between the two is determined by the staff through multiple tests in advance, which will not be elaborated here.

[0051] Step S402: Calculate and update the frequency adjustment load based on the urgent load adjustment and the frequency adjustment load.

[0052] The frequency adjustment load can be updated by adding all the rapid adjustment loads to the frequency adjustment load, thereby improving the accuracy of data analysis.

[0053] After the execution load of the solution is determined, the printing management method based on plastic cup production also includes: Step S500: Determine whether the minimum execution load of the solution is less than the preset required execution load.

[0054] The demand execution load is the maximum execution load allowed when the production effect of the solution set by the staff is excellent. The purpose of the judgment is to know whether there is an effective allocation solution with excellent production effect.

[0055] Step S5001: If the minimum execution load of the scheme is not less than the required execution load, then the effective allocation scheme corresponding to the minimum execution load of the scheme is defined as the allocation scheme to be used.

[0056] When the minimum execution load of the solution is not less than the required execution load, it means that even the most suitable and effective allocation solution cannot achieve the best results. Therefore, it is normal to define it as using the allocation solution for subsequent production control.

[0057] Step S5002: If the minimum execution load of the scheme is less than the required execution load, then the effective allocation scheme corresponding to the execution load of the scheme that is less than the required execution load is defined as the alternative allocation scheme.

[0058] When the minimum execution load of the solution is less than the required execution load, it indicates that there is a solution that can achieve excellent production results. Therefore, the current assessment of the load situation can be slowed down. Thus, alternative allocation schemes are defined to identify and distinguish different effective allocation schemes for the convenience of subsequent analysis.

[0059] Step S501: Analyze the single-line printing time in the alternative allocation scheme to determine the batch printing time.

[0060] Batch printing time is the maximum time required to process the current batch of print orders based on alternative allocation schemes, which is also the maximum single-line printing time.

[0061] Step S502: Calculate and determine the alternative selection coefficient based on the batch printing time and the execution load of the scheme, and define the alternative allocation scheme corresponding to the largest alternative selection coefficient as the allocation scheme to be used.

[0062] The alternative selection coefficient is a parameter that reflects the feasibility of using alternative allocation schemes as allocation schemes. The larger the value, the more suitable the alternative allocation scheme is as allocation scheme. It is determined by adding the batch printing time and the scheme execution load in a unified dimension and taking the reciprocal. At this time, the alternative selection coefficient with the largest value indicates that the corresponding alternative allocation scheme is the most suitable, so it can be defined as the allocation scheme to be used.

[0063] After the alternative selection coefficients are determined, the printing management method based on plastic cup production also includes: Step S600: Determine whether there are at least two alternative allocation schemes with the same and largest alternative selection coefficients.

[0064] The purpose of the judgment is to determine whether there are multiple alternative allocation schemes that meet the requirements, so as to determine the unique allocation scheme.

[0065] Step S6001: If there are no at least two alternative allocation schemes with the same and largest alternative selection coefficient, then the alternative allocation scheme corresponding to the largest alternative selection coefficient is defined as the allocation scheme to be used.

[0066] When there are no at least two alternative allocation schemes with the same and largest selection coefficient, it means that there is only one alternative allocation scheme that meets the requirements, so it can be defined as the allocation scheme to be used.

[0067] Step S6002: If there are at least two alternative allocation schemes with the same and largest alternative selection coefficient, then the alternative allocation scheme corresponding to the largest alternative selection coefficient is defined as the alternative allocation scheme.

[0068] When there are at least two alternative allocation schemes with the same and largest selection coefficients, it indicates that there are multiple alternative allocation schemes that meet the requirements. Therefore, these are defined as candidate allocation schemes to distinguish between different alternative allocation schemes and facilitate subsequent analysis.

[0069] Step S601: Under the alternative allocation scheme, calculate the average adjacent adjustment load based on the adjacent adjustment load of each individual printing scheme to determine the adjacent average load.

[0070] The adjacent average load is the average of the adjacent adjusted loads across all individual printing schemes.

[0071] Step S602: Calculate the load concentration value based on the adjacent average load and each adjacent adjusted load, and define the candidate allocation scheme corresponding to the largest load concentration value as the allocation scheme to be used.

[0072] The load concentration value reflects the deviation between adjacent adjusted loads. The larger the value, the smaller the deviation between adjacent adjusted loads, which means that it is less likely to have a large load when adjusting the feeding timing of local tasks. It is determined by calculating the difference between the adjacent average load and each adjacent adjusted load, summing the absolute values ​​of the differences and taking the reciprocal. The maximum load concentration value indicates that the corresponding alternative allocation scheme has a better overall effect, so it can be determined as the allocation scheme to be used.

[0073] The steps for feeding and printing plastic cup preforms according to the distribution scheme include: Step S700: Obtain equipment wear value.

[0074] Equipment wear value is a parameter that reflects the degree of equipment monitoring. The smaller the value, the healthier the equipment is, meaning it can handle high-load operations. Specific values ​​can be obtained from the registration data of each piece of equipment.

[0075] Step S701: Determine the equipment health sequence by sorting the equipment wear values ​​from smallest to largest.

[0076] The equipment health sequence is the order obtained by sorting each printing production line according to the wear value of the equipment from smallest to largest.

[0077] Step S702: Perform plastic cup preform feeding and printing operations on each production line according to the equipment health sequence and equipment load adjustment in conjunction with the allocation scheme.

[0078] At this point, the high-load scheme of the equipment is assigned to the production line with low equipment wear value, so that the production line with high health can execute the high-load scheme, thereby reducing the probability of equipment damage during production. In addition, this setting can keep the health of each production line at the same level as much as possible. When one production line fails, other production lines can be inspected and processed simultaneously during the downtime, which is convenient for overall equipment maintenance.
