A deoxidizer self-adaptive bag length cutting and detection method for missing and sandwiched materials

Abstract

The invention discloses an adaptive bag length cutting and starving and pinching detecting method for deoxidizers. The adaptive bag length cutting and starving and pinching detecting method includes detecting whether the deoxidizers are available or not by the aid of photoelectric tubes to obtain detection information of opening and closing contact states; acquiring the positions of deoxidizer bags by the aid of photoelectric encoders and acquiring information of the deoxidizer bags; identifying and detecting adaptive cutting parameters of the information of the deoxidizer bags according to the detection information of the opening and closing contact states so as to obtain parameter information of the deoxidizer bags; combining the parameter information of the deoxidizer bags with information of the positions of the photoelectric tubes and cutters according to the detection information of the opening and closing contact states so as to obtain interference removal judging models, starving and pinching detecting models and adaptive cutting models, performing interference removal judgment and starving and pinching detecting judgment and implementing adaptive bag length cutting on the deoxidizers. The adaptive bag length cutting and starving and pinching detecting method has the advantages that mechanical mounting structures of common cutting machines can be simplified, adaptive cutting can be carried out on the deoxidizers with different bag lengths from different factories, the shortcoming that machines need to be frequently adjusted can be overcome, and the deoxidizer production qualified rate can be increased.

Description

technical field [0001] The invention belongs to the field of food machinery, and in particular relates to a deoxidizer self-adaptive bag length cutting and a method for detecting material shortage and inclusion. Background technique [0002] With the development of the food industry and the improvement of packaging materials, deoxidizers, as new materials for food preservation, have received more and more attention in China, and their applications have become more and more extensive. In industrial production, deoxidizers are usually manufactured in rolls, which need to be cut into individual pouches before they can be used in food processing. The old manual cutting can no longer meet the needs of modern production because it consumes a lot of manpower and time. At present, the demand for deoxidizer cutting equipment in China is growing very fast. [0003] At present, for the deoxidizer cutting equipment widely used in the market, generally only one bag length can be cut ind...

Problems solved by technology

[0004] (1) Frequent adjustments will loosen the photocell and the cutting edge, and the resulting mechanical wear will affect the accuracy and service life. At the same time, human operation will also bring accidental errors.

[0005] (2) It is impossible to detect the lack of material and the inclusion of material by the traditional method. The lack of material will cause the deoxidizer dose to be unqualified and cannot be put into food safety use, and the material inclusion will cause the material to spill during the cutting process. The deoxidizer material is generally There are iron series and sulfite substances, so it will pollute the cut strip and cannot be used
