Control system of secondary packaging equipment for small packaging bags

Abstract

The invention relates to a control method for secondary packing equipment of small packing bags. A stop button, a start button and a coil of a first relay are in series connected between a control loop live line and a zero line in sequence; a normally open contact of the first relay is in series connected between the start button and an induction switch header live line; a grip closing induction branch, a grip opening induction branch and a grip dropping induction branch are connected between the induction switch header live line and the zero line; the grip closing induction branch comprises a grip closing induction switch and a coil of a second relay which are in series connected to each other; the grip opening induction branch comprises a grip opening induction switch and a coil of a third relay which are in series connected to each other; the grip dropping induction branch comprises a grip dropping induction switch and a soil of an eighth relay which are in series connected to each other; and a normally open contact of the eighth relay, a normal open contact of the second relay, a normally closed contact of the third relay and a coil of a grip air cylinder electromagnetic reversing valve are in series connected between the start button and the zero line in sequence. The system can be used for filling the small packaging bags into large packaging bags in good order.

Description

technical field [0001] The invention relates to secondary packaging control equipment for small packaging bags, in particular to a control system for secondary packaging equipment for small packaging bags, and belongs to the technical field of industrial automatic control. Background technique [0002] With the miniaturization of social units and changes in people's consumption habits, the packaging of household food raw materials is gradually miniaturized. For example, when large packages such as rice and flour enter the family, they are inconvenient to carry and eat for a long time due to food diversification. People mostly choose small packages or even bulk products when purchasing these food raw materials. Due to its easy-to-carry, food-safe and traceable attributes, small-package products are gradually accepted by the public and transformed into consumption habits. Due to market factors, various food manufacturers have increased the proportion of small packaged flour (...

AI Technical Summary

Problems solved by technology

[0004] The small bags need to be neatly and orderly loaded into the big bag, and the shape should be uniform. Unordered bagging is prone to cause the big bag to be overfilled and difficult to sew, or the small bags are concentrated at the bottom of the big bag, and after the small bags are disorderly loaded into the big bag, due to local concentration, the follow-up automation of the big bag Stacking cannot be achieved

Based on the above difficulties, the current secondary packaging of soft bag products such as rice and flour is basically manual work, the packaging quality is not stable, and it is easy to cause damage; flour or rice flour will be produced during the bagging process, and the working environment for workers is poor; due to the quantity Huge, high labor intensity, high labor costs, and a large demand for secondary automated packaging of small bag packaging products
