Boxing apparatus and packaging apparatus

Abstract

The invention provides a boxing apparatus (100) for boxing bags of predetermined weight or a predetermined number of bags comprises a collecting section (5), a group weight checker (6), a control section (10), and a boxing / sealing section (7). The collecting section (5) collects bags and makes a group of bags. The group weight checker (6) weighs the group of bags. The control section (10) judges appropriateness to box the group of articles on the basis of the weight value measured by the group weight checker (6). The boxing / sealing section (7) boxes groups of bags each of which is judged appropriate to be boxed by the control section (10). With this, a failure that there is a missing article is detected before boxing and an appropriate measure can be taken. As the result, the boxing apparatus operates less wastefully than conventional boxing apparatuses which judge appropriateness of the weight of bags (the number of those) after completion of the boxing and reject the whole box whose inappropriateness is found out from its production line.

Description

technical field [0001] The present invention relates to a boxing device which accumulates a plurality of individual articles into a group and packs a plurality of such a group of articles, thereby packing articles of a predetermined weight or a predetermined number into one box. In addition, the present invention relates to a packaging device for packaging a plurality of articles having known weight values ​​in an outer packaging body. Background technique [0002] As a boxing device for packing items of a specified weight or a specified number into a box, the following technology has been proposed: the weight value of each individual item is measured, and a combination of items reaching a target weight is formed based on the weight value, so that The weight of the packed article reaches an appropriate value (for example, refer to Patent Document 1). [0003] However, in a boxing device that packs articles of a prescribed weight or a prescribed number into one box by gather...

AI Technical Summary

Problems solved by technology

[0005] However, when the overall weight is inspected after the packing is completed and it is determined that the packing weight (number) is not appropriate, the entire box containing the articles must be removed from the production line, resulting in low production efficiency

In addition, when the total number of items loaded into one box is large and the deviations in the weight values ​​of each item are multiplied, it is impossible to distinguish whether the weight fluctuation of the entire box is due to the absence of items or the weight of individual items. Due to the deviation of the value, such boxes can only be removed from the production line as defective.
