Description

Technical Field

[0001] The present invention relates to the technical field of online detection of wire package unwinding, and in particular to an intelligent switching method for external power supply of a frequency converter fan. Background Art

[0002] The unloading cart for the South Slicing Line is equipped with three sets of photoelectric sensors. When the finished wire bales produced by the baler are 1.8-2.0 meters long, the unloading cart's photoelectric sensors detect the rolled material and transmit a signal to the PLC, which begins scanning and starting the unloading process for bales 1-5. Furthermore, when the finished rolled material bales are 1.32-1.45 meters long, the "Unloading 2# Small Package" option is selected on the system's WinCC screen. The three sets of photoelectric sensors in the middle detect the number of small packages, 1-4, and initiate unloading.

[0003] During production, it was found that when the number of small rolls to be unloaded reached five, the following problems occurred:

[0004] 1. There is no shooting switch on the unloading trolley to detect five small rolls, which means that it is unable to identify more than four small rolls.

[0005] 2. The PLC program does not include a program for automatically unloading the five small rolls. Even if the position of the five small rolls can be detected, the rolls cannot be automatically unloaded.

[0006] Therefore, it is necessary to design a high-speed wire unloading coil package length automatic identification method to solve the problem that the existing slitting line cannot accurately identify the unloading work of more than four coils during the automatic unloading process of the unloading trolley, causing the system to work unstable and require shutdown for maintenance. Summary of the Invention

[0007] In view of the problems existing in the prior art, the object of the present invention is to provide a method for automatically identifying the length of a high-speed wire unwinding package.

[0008] The technical solution adopted by the present invention to solve the technical problem is: a method for automatically identifying the length of a high-speed wire unwinding package, comprising the following steps:

[0009] S1. Establish a model for identifying the length of finished high-speed wire packages with 1 to 5 rolls;

[0010] S2. Set the detection point. When the length of the high-speed wire finished package is 1.32-1.45 meters, the coil will be automatically unloaded.

[0011] S3, the system sets the variable name of the detection point and the corresponding PLC working circuit;

[0012] S4. Set up misoperation protection logic in the PLC working circuit.

[0013] Specifically, the high-speed wire finished product package length recognition model in step S1 recognizes the unloading trolley with a package length of 1.8-2.0 meters, and five groups of photoelectric switches are installed on both sides of the running direction of the unloading trolley.

[0014] Specifically, the corresponding positions of the opposing photoelectric switches are numbered I87.1, I87.2, I87.3, I87.4, and I87.5.

[0015] Specifically, the photoelectric switch in step S2 automatically detects the small packages. When there are five or fewer high-speed wire finished product packages with a length of 1.32-1.45 meters that need to be unloaded at the same time, the system automatically recognizes it and automatically unloads the packages.

[0016] Specifically, the variable names of the detection points set by the system in step S3 include unloading roll 2 small package unloading position 2, unloading roll 2 small package unloading position 3 and unloading roll 2 5th roll photoelectric detection switch. The system takes the internal variable 163.0 of the Botu software and connects it to this system as the automatic switch for unloading the fifth small roll.

[0017] Specifically, the working mode of the PLC working circuit in step S3 is to check the two options of small roll automatic and five small roll unloading in the system. At this time, through online detection through the Botu software, when it is necessary to unload five small rolls of wire, first the small roll automatic switch DB10.DBX0.0 is energized, the unloading and five small roll unloading switch M163.0 is energized, and the SR trigger M163.1 is set and energized, and the on-site unloading trolley starts to work normally.

[0018] Specifically, the misoperation protection logic in step S4 sets a reset priority trigger to ensure that the equipment is not damaged due to misoperation. If any of the unloading and five-small-roll switch M163.0 and the small-roll automatic switch DB10.DBD0.0 is not selected, the equipment cannot operate.

[0019] The present invention has the following beneficial effects:

[0020] The method for automatically identifying the length of high-speed wire unloading packages designed by the present invention automatically detects small packages through a corresponding photoelectric detection switch. By checking the box on the system wincc screen, when there are less than or equal to five high-speed wire finished product packages with a length of 1.32-1.45 meters that need to be unloaded at the same time, the system can still recognize and automatically unload them, thereby improving system operation stability, increasing production line operation efficiency, and reducing production costs.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely further describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] The present invention mainly uses the automatic identification technology of the length of high-speed wire finished product packages to realize that when the southern production line is cut and produced, the package length is 1.8-2.0 meters and the number of rolls is 1-5. The unloading trolley can identify the wire products, accurately locate the products through the forward and reverse solenoid valves of the unloading trolley, and transport the products back to the platform to continue the next operation. The closed-loop control technology is as follows: Figure 1 shown.

[0026] like Figure 1-Figure 3 As shown, a method for automatically identifying the length of a high-speed wire unwinding package includes the following steps:

[0027] 1. Build a model for identifying the length of finished high-speed wire packages with 1-5 rolls. This model identifies unloading carts with package lengths between 1.8 and 2.0 meters. Install five sets of photoelectric switches on either side of the unloading cart's direction of travel. The corresponding positions of the photoelectric switches are numbered I87.1, I87.2, I87.3, I87.4, and I87.5.

[0028] 2. Set the detection point. When the length of the high-speed wire finished product package is 1.32-1.45 meters, the roll will be automatically unloaded. The photoelectric switch automatically detects small packages. When there are five or fewer high-speed wire finished product packages with a length of 1.32-1.45 meters that need to be unloaded at the same time, the system automatically recognizes it and automatically unloads the packages.

[0029] 3. The system sets the variable name of the detection point and the corresponding PLC working circuit; to solve the problem of simultaneous production of two cutting production lines, the present invention increases the production rhythm and improves production efficiency: an automatic program for the unloading trolley with five small rolls is written in the Botu software.

[0030] The variable names of the detection points set by the system include unloading roll 2 small package unloading position 2, unloading roll 2 small package unloading position 3 and unloading roll 2 5th roll photoelectric detection switch. The system takes the internal variable 163.0 of the Botu software and connects it to this system as the automatic switch for unloading the fifth small roll.

[0031] The working mode of the PLC working circuit is to check the two options of small roll automatic and unloading five small rolls in the system wincc screen. At this time, through the online detection of the Botu software, when it is necessary to unload five small rolls of wire, first the small roll automatic switch DB10.DBX0.0 is energized, the unloading five small rolls switch M163.0 is energized, and the SR trigger M163.1 is set and energized, and the on-site unloading trolley starts to work normally.

[0032] 4. Set up misoperation protection logic in the PLC working circuit. To prevent equipment damage caused by misoperation, set a reset priority trigger. If either the unloading and unloading five small rolls switch M163.0 or the small roll automatic switch DB10.DBD0.0 is not selected, the equipment will not operate.

[0033] This invention designs automatic wire package identification technology, which is crucial for production stability and workflow upgrades. It automatically detects small packages through a photoelectric detection switch. By selecting a checkbox on the system's WinCC screen, the system can identify and automatically unload five or fewer high-speed wire packages 1.32-1.45 meters long when they need to be unloaded simultaneously, improving system stability, increasing production line efficiency, and reducing production costs.

[0034] The present invention is not limited to the above-mentioned embodiments. Anyone should be aware that any structural changes made under the guidance of the present invention, and any technical solutions that are the same or similar to those of the present invention, fall within the scope of protection of the present invention.

[0035] The technology, shape, and structure not described in detail in the present invention are all well-known technologies.
