In summary, the problems of the prior art are as follows:
(1) the existing steel shearing processing warehousing method has the problem that warehousing personnel collect the pound order and take longer time.
(2) At present, the steel shearing processing warehousing method has wrong writing or abnormal weighing when batch numbers are written on a weighing sheet, and the checking time is long.
(3) The existing steel shearing processing warehousing method is easy to lose due to the fact that the steel is stuck or clamped on a task list.
(4) The existing steel shearing processing warehousing method has the defect that finished product information is very easy to make mistakes when the balance sheet is required to be recorded.
(5) The existing steel shearing processing warehousing method has the hysteresis of warehousing time, more warehousing delay time and low warehousing efficiency.
The difficulty of solving the technical problems is as follows: 1. if a plurality of workers collect the pound order, the cost of the workers is high, and the labor division of the post is difficult; 2. if the packer directly writes, the workload of the packer is increased, writing data errors are easy to occur, and rework checking time is long; 3. the special person collects the pound bill, and the special person enters the pound bill, so that the labor cost is high, and when the workload is small, the pound bill collecting single person needs to rearrange the work; 4. if an MES workshop management system (including code scanning and warehousing) is introduced, the investment cost is at least more than 30 ten thousand, and the financial cost is high for part of enterprises.
The significance of solving the technical problems is as follows: 1. the warehousing process is simplified, and the workload of warehousing workers is reduced; 2. and warehousing is timely, the products can be delivered after being produced, and the warehousing and delivery efficiency of enterprises is improved.
