At present, after a customer selects to bag vegetables and fruits for selling in various large comprehensive supermarkets, medium and small supermarkets, retail stores and vegetable and fruit exclusive-selling stores, the customers are handed to a weigher to weigh, prick and stick price labels. The process is repeated mechanically, and during the shopping peak period, a weigher should take no time, so that the labor intensity is high. In addition, the low weighing efficiency also causes the queuing phenomenon of customers, so that the customer experience is poor and the supermarket benefit is reduced. There is also an independent settlement device in the market, and customers can settle accounts by scanning commodity bar codes by themselves, but the premise is that commodities are provided with price bar codes, and the price bar codes do not help scattered vegetables and fruits except for part of vegetables and fruits which are packed in advance. In summary, at present, no equipment capable of automatically weighing and settling accounts for bulk commodities such as vegetables and fruits exists, so that the selling efficiency is improved, the labor intensity of workers is reduced, and the labor cost investment is reduced.
