All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
The embodiment of the invention provides a method for detecting the accuracy of a weighing machine on a steel coil tray transportation line, and with reference to fig. 1, the method comprises the following steps:
step S110: and when the steel coil is conveyed and put in storage, controlling the steel coil tray conveying line to be in an automatic operation mode.
Particularly, the method can be carried out in normal production operation at random in the embodiment of the application, when the steel coil is conveyed and put in storage, a tray conveying mode can be adopted, the steel coil tray conveying line is set to be in an automatic operation mode for detecting the accuracy of the online weighing machine, namely, at the moment, the conveying line automatically conveys the tray, the weighing machine automatically weighs, and the weighing accuracy is prevented from being influenced by human factors.
Step S120: conveying a single empty tray to the steel coil tray conveying line, and driving the empty tray to automatically operate through the operation of the steel coil tray conveying line;
step S130: and controlling the empty tray to run to reach the weighing machine to automatically stop, so that the weighing machine displays the weight data of the empty tray.
Particularly, post operating personnel can manually put single empty tray on carrying coil of strip tray conveying line, empty tray automatic operation on the conveying line, when empty tray operation reachs weighing machine department, can automatic shutdown to direct operation reachs on the weighing machine, through weighing machine is single the weight of empty tray, and show in real time on the monitor display system the weight data of empty tray.
Step S140: judging whether the weight data is within a specified weight deviation range;
step S150: and when the weight data is within the specified weight deviation range, determining that the weighing machine is in a normal working state.
In particular, the national standard (0.3%) for the delivery weight deviation of steel coils is combined according to the structural characteristics and the economy of the pallet transport line. The post operator can compare the weight data of the empty pallet with a specified weight deviation range and judge whether the weight data is within the specified weight deviation range. When the weight data is within the specified weight deviation range, if the weight deviation of the online tray required by a certain strip steel production plant is within +/-10 kg, namely the weight deviation of the randomly weighed empty tray is within +/-10 kg, the weighing machine can be determined to be in a normal working state, and the accuracy of the weighing machine is good.
Further, the method further comprises: when the weight data exceed the specified weight deviation range, sequentially conveying M empty trays to the conveying steel coil tray conveying line, wherein M is a positive integer; controlling the M empty trays to sequentially arrive at the weighing machine, so that the weighing machine respectively weighs the M empty trays, and obtaining M weight data; judging whether the M weight data are within a specified weight deviation range; and when the weight data below M/2 is within the specified weight deviation range, determining that the weighing machine is in a distorted state.
Further, M is greater than or equal to 3 and is a positive integer.
Specifically, when the post operator compares the weight data of the empty pallet with a specified weight deviation range, the weight data exceeds the specified weight deviation range, and the post operator can further verify and check whether the pallet has a fault. The post operator can operate to sequentially place 3 or 4 empty trays on the conveying steel coil tray conveying line, the number of the empty trays is not limited, but 3 empty trays are generally selected for improving the working efficiency. When the 3 empty trays sequentially arrive at the weighing machine, the weighing machine respectively weighs the 3 empty trays, the weight of the 3 empty trays is displayed on the monitoring display system in real time, and a post operator can respectively compare the weight data of the 3 empty trays with a specified weight deviation range to judge whether the weight data is in the specified weight deviation range. When the weight data of only one empty tray is within the specified weight deviation range, the weighing machine is determined to be in a distorted state, and a post operator can contact a professional to maintain the machine, so that the method avoids the problem that a large batch of steel coils need to be frozen after the steel coils are put in storage due to weight defects, collects a large amount of data, analyzes and conjectures the distorted section of the weighing machine, screens the information of the steel coils, and accordingly causes the weight loss of the steel coils.
Further, the method further comprises: when more than M/2 weight data are within the specified weight deviation range, recording the number of the empty tray corresponding to the weight data which are not within the specified weight deviation range; and hanging the empty trays which are not within the specified weight deviation range away from the conveying steel coil tray conveying line.
Specifically, when the weight data of more than two empty pallets is within the specified weight deviation range, the numbers of the empty pallets exceeding the specified weight deviation range are recorded, and the empty pallets exceeding the specified weight deviation range are lifted away from the steel coil conveying pallet conveying line by a professional operator for processing.
Further, the method further comprises: passing a steel coil through the steel coil tray conveying line and weighing a first weight on the weighing machine; weighing a second weight of the quantitative steel coil by a coil warehouse weighing machine; judging the difference value between the first weight and the second weight; and when the difference value of the first weight and the second weight meets a preset condition, determining that the weighing machine is in a normal working state.
Further, the predetermined condition is that the deviation range of the weight difference is within ± 10 kg.
Particularly, in order to verify the accuracy that the method that the tray was weighed on the conveying line of application embodiment detected weighing machine, can be after the detection, pass through a quantitative coil of strip the coil of strip tray conveying line and weigh on the weighing machine the first weight of quantitative coil of strip will quantitative coil of strip is weighed through coil storehouse weighing machine the second weight of quantitative coil of strip. And comparing whether a difference exists between the first weight and the second weight, and judging whether the difference meets a preset condition, wherein if the preset condition is that the weight difference deviation is within +/-10 kg, the difference deviation is not limited, and the difference deviation is mainly a numerical range which is smaller than the delivery deviation of the national standard product weight and is set by professionals in a factory. When the difference value of the first weight and the second weight is within +/-10 kg, the weighing machine is determined to be in a normal working state, and meanwhile, the accuracy of determining the coil stock weighing machine can be checked.
The technical scheme provided in the embodiment of the application at least has the following technical effects or advantages:
