Description
Technical Field
The application relates to the technical field of furniture manufacturing, in particular to a furniture punching procedure flexible matching system and method based on the industrial Internet.
Background
Furniture (especially wooden furniture) products have a greater variety of forms and stronger custom properties. In the structure of furniture, various connecting holes and functions Kong Xingtai are more, and punching is the main workload of furniture production. Moreover, as various holes are processed by intelligent equipment, and the MES system is accessed to carry out networking intelligent execution, the value of the equipment is usually higher, and the matching quantity is limited. Therefore, the punching process of furniture is usually a bottleneck-level processing process of furniture production enterprises, and has important significance for management, innovation and promotion of the process and value optimization of the whole furniture production process. Wherein flexible scheduling of hole-punching process orders based on flexible matching algorithms is considered an effective means.
The conventional flexible matching algorithm generally adopts a mode of estimating a certain value or dynamically correcting through empirical big data on the working capacity parameters of each punching device. In the method, a certain value is estimated in a manner that inaccurate estimation usually occurs in actual production, and if the estimated value exceeds an actual capacity value, the problem of excessive production and processing backlog occurs. It is common practice to make conservative predictions, i.e. the predicted value is usually smaller than the actual capacity value, which would lead to the disadvantage of wasted capacity. The mode of dynamic correction through big data generally adopts historical data to carry out statistics and average, and the mode seems to alleviate the problem of productivity waste or material congestion to a certain extent, but the congestion or the productivity waste still exists when aiming at a specific production behavior, and this leads to the management of the post to keep continuous tracking for a long time and solve the problem in time.

Example 1:
referring to fig. 1, fig. 1 is a schematic structural diagram of a furniture punching procedure flexible matching system based on an industrial internet according to an embodiment of the present application.
As shown in fig. 1, a furniture punching process flexible matching system based on the industrial internet comprises: an order resolution module 10, a capacity calculation module 20, and a process scheduling module 30.
Wherein, the order analysis module 10 is configured to analyze and extract the order task quantity and the order task time limit in the order task when receiving the order task; the capacity calculation module 20 is configured to obtain a unit capacity of each punching device, and determine a term capacity of each punching device according to the unit capacity and the order task term; the process scheduling module 30 is configured to generate a punching task for each punching device to execute, based on the deadline capacity of each punching device, subject to the order task amount and the order task deadline.
It should be noted that the existing furniture manufacturing process includes board drying, board cutting, woodworking, board painting, installation and packaging, etc., where the woodworking is a process of processing all parts of a product from raw materials to shapes and sizes required by drawing, and there is a very critical operation step in the woodworking, that is, punching, the holes of the parts directly affect the quality of the furniture product, and the furniture cannot be normally installed due to misalignment of the hole pairs. When punching, the plate needs to be placed on a numerical control machine tool, the plate is positioned, punched and turned, then punched and taken down, the punching precision requirement is higher, the punching equipment is the most intelligent and highest-cost equipment in the whole furniture manufacturing process, the punching equipment is effectively utilized under the condition that the quantity of the punching equipment is limited, but in the existing furniture production process, part of the punching equipment is often idle, the part of the punching equipment is excessively produced, and the utilization rate of the punching equipment is lower. In addition, in the prior art, a plurality of delivery conditions often occur for one furniture order, namely, the products of one order are delivered in a plurality of time periods, so that the problems of time trouble, space trouble, progress trouble and the like can be caused for a user, and very poor experience is brought to the user.
Therefore, the embodiment provides a flexible matching system for a furniture punching process based on the industrial internet, after a receiving signal passes through a radio frequency front end, the time limit productivity of each punching device is determined according to the order task time limit by acquiring the order task quantity and the order task time limit from the order task, and the punching task executed by each punching device is generated by utilizing the time limit productivity, the order task quantity and the order task time limit, so that flexible matching of the furniture punching process is realized, waste of productivity or material congestion possibly occurring during furniture punching processing can be solved, and the production efficiency of enterprises is improved. Compared with the traditional flexible matching algorithm, the method has the advantages that based on the mode of the order task quantity and the order task time limit, the punching task of each punching device is calculated, so that the total task quantity of the order is completed before the order task time limit, the furniture order can be ensured to be delivered at the same time before the interaction time, and the trouble caused by multiple delivery to a user is avoided.
In a preferred embodiment, the order resolution module 10 includes: an order task disassembling unit configured to extract order information of an order task when the order task is received; wherein the order information includes order delivery furniture and order mission terms; the order task analysis unit is configured to call a furniture database and match the order task quantity corresponding to the order delivery furniture. The furniture database comprises a plurality of furniture data packets, wherein each furniture data packet is provided with part composition information of target furniture and punching information of each part; the punching information comprises punching quantity and punching type; the different punching types are provided with different preset task amounts, and the task amounts of the orders are the sum of the task amounts of the corresponding punching information of the furniture delivered by each order.

It should be noted that, when determining the deadline capacity, the present embodiment considers the processing task that each punching device currently has, obtains the queuing task amount of each punching device in the invoked device processing task list, and subtracts the queuing task amount from the theoretical capacity, that is, the deadline capacity that each punching device can reach when the order task is scheduled, thereby more accurately calculating the capacity of each punching device, providing more accurate data for the scheduling algorithm, and further improving the utilization rate of the punching device.
In a preferred embodiment, the industrial internet-based furniture perforation process flexible matching system further comprises: the production capacity list generation module of the punching equipment; wherein, the punching equipment productivity list generation module comprises: a standard productivity determining unit configured to acquire a standard productivity of each punching apparatus in a standard processing person and a standard use state; the personnel correction coefficient determining unit is configured to acquire the scheduling information of the machining personnel of each punching device, determine the machining personnel corresponding to each machining period according to the scheduling information of the machining personnel, and match the personnel correction coefficient corresponding to each machining period in a comparison table of the machining personnel and the personnel correction coefficient; a usage correction coefficient determining unit configured to acquire identification information of each punching device, and determine a usage correction coefficient corresponding to each processing cycle according to the identification information; and a punching equipment capacity list generation unit configured to generate a punching equipment capacity list of each punching equipment according to a product of a standard capacity of each punching equipment in each processing cycle, a personnel correction coefficient, and a usage correction coefficient.
It should be noted that, during punching, a worker is required to operate the numerical control punching device, such as plate replacement, startup, punching, shutdown, etc., and the proficiency and operation level of the worker also directly affect the productivity of punching, so that accurate estimation of productivity is very important. The capacity of a punching device is not only related to the device itself but also to the staff using the device. The regular wear products (such as turners, cutters and the like) in the punching process are repaired or replaced, which is difficult to predict by historical big data statistics. The service life of the cutter is related to the material, the punching type and the punching quantity of the punched plate, and especially when the plate with higher hardness is continuously punched, the service life of the cutter is severely reduced due to the abrasion of the cutter, and the frequency of replacing the cutter is increased. The tool is replaced many times in a short time, and the effective working time of the tool is greatly reduced in the same time period, so that the service life of the tool estimated by taking an average value in the prior art is inaccurate.
In this embodiment, the standard machining personnel is defined as a person having an average operation proficiency of a plurality of machining personnel of the punching apparatus, and the standard use state is defined as the productivity of the punching apparatus when the tool is not required to be replaced. According to the method and the device, errors brought to productivity estimation are avoided due to the fact that the personnel correction factors are used for avoiding the difference of the operation levels of the workers, the correction factors are used for taking the time of tool replacement into consideration, so that the quantity estimation of standard holes of the standard plate in one working period of the punching equipment is more accurate, the total productivity of the punching equipment to the punching deadline is accurately estimated, more accurate data are provided for a scheduling algorithm, and the utilization rate of the punching equipment can be improved.
Specifically, the punching equipment capacity list generation module includes: a personnel correction coefficient calculation unit configured to determine a personnel correction coefficient according to a ratio of a number of holes punched in a unit time of a processing personnel in the target punching apparatus to a number of holes punched in a unit time of all processing personnel of the target punching apparatus; and the personnel correction coefficient comparison table generation unit is configured to establish a personnel correction coefficient comparison table of different processing personnel in corresponding punching equipment according to the personnel correction coefficient of each processing personnel in the corresponding punching equipment. According to the method and the device, the productivity is corrected through the personnel correction coefficient, the productivity calculation error caused by staff skill difference and habit difference can be reduced, the productivity can be calculated more accurately, the task allocation of the scheduling algorithm is more accurate, and the utilization rate of punching equipment is increased.
Specifically, each of the furniture data packages also has a sheet type for each part; wherein, the parts of different plate types have preset different equivalent proportions of task amounts when executing the same punching task. It should be noted that, since there are various kinds of boards for wooden furniture, for example: particle board, joinery board, oak board, pine board, density board, maple board, water yeast Liu Ban, etc., different types of boards have different hardness and density, the same cutter/the same rotating speed is used for punching holes of the same type on different boards, the abrasion of the cutter is different, the punching time is different, and therefore, only the number of punching holes is calculated, and the type of the punching boards is not considered, so that the estimation of the order task amount is deviated from an actual value.
On this basis, the usage correction factor determining unit includes: a first time determining subunit configured to determine a first time according to a processing time between every two tool changes in historical processing data of each type of punching performed on the part of each type of sheet by the target punching apparatus; a second time determination subunit configured to determine a second time from a sum of the first time and a time for which the target punching apparatus performs one tool change in the historical machining data for each type of punching for the part of each type of sheet; a use correction coefficient calculation subunit configured to calculate a use correction coefficient from a ratio of the first time to the second time; and a use correction coefficient determination subunit configured to determine a use correction coefficient when the punching apparatus performs the punching task of the target punching type on the part of the target plate type, based on the identification information of the punching apparatus. The correction coefficient used in the application is obtained according to the actual conditions of each punching device, so that the influence of the replacement of the cutter on the productivity estimation is avoided, the productivity estimation is more accurate, and the high-efficiency utilization of the punching device is more facilitated.
