Weighing and removing machine

Abstract

The invention discloses a weighing and removing machine. The weighing and removing machine comprises two dynamic weighing mechanisms, a PLC (programmable logic controller) control cabinet control system, a removing mechanism and a temporary storage mechanism, wherein one of the two dynamic weighing mechanisms is provided with the PLC control cabinet control system; the removing mechanism is connected with the dynamic weighing mechanism provided with the PLC control cabinet control system; and the temporary storage mechanism is connected with the removing mechanism. The weighing and removing machine disclosed by the invention is a dynamic weighing and removing machine capable of realizing secondary detection, accurately detecting the product net weight after boxing, enabling the qualified products to smoothly pass the detection, removing the unqualified products into an appointed unqualified product region, and giving an alarm and is suitable for a large-scale automatic production line with strong detection capability. The weighing and removing machine is accurate to detect the product net weight, high in precision, fast in detection speed and strong in product adaptability, and is capable of meeting the urgent demands of large-scale automatic production.

Description

technical field [0001] The invention relates to packaging machinery, in particular to a weighing and rejecting machine. Background technique [0002] At present, the weighing machines produced by many packaging machinery factories at home and abroad use more than once to detect the total weight of the packed product, and the tare weight is only an average value weighed in advance. The difference in weight affects the accuracy of the net weight of the product in the detection box. The detected net weight of the product in the box fluctuates greatly and is unstable. It is difficult to meet the automatic production requirements of high accuracy of the net weight of each box, and to change the setting when changing the product variety frequently. The weight parameters of the packaging boxes are also very frequent, which is not convenient for quick and quick replacement of varieties. According to many factors, it is urgent to design a weighing and rejecting machine capable of sec...

[0002] At present, the weighing machines produced by many packaging machinery factories at home and abroad use more than once to detect the total weight of the packed product, and the tare weight is only an average value weighed in advance. The difference in weight affects the accuracy of the net weight of the product in the detection box. The detected net weight of the product in the box fluctuates greatly and is unstable. It is difficult to meet the automatic production requirements of high accuracy of the net weight of each box, and to change the setting when changing the product variety frequently. The weight parameters of the packaging boxes are also very frequent, which is not convenient for quick and quick replacement of varieties. According to many factors, it is urgent to design a weighing and rejecting machine capable of secondary detection, which can accurately detect the net weight of products. The qualified products pass smoothly, and the unqualified Products are rejected to the designated non-conforming product area, and an alarm is issued to meet the needs of large-scale automated production lines with strong detection capabilities
