Problems solved by technology

[0005] However, in the prior art, the production line runs at high speed. During the production process, the glue spray head of the glue machine is easy to accumulate glue due to clogging and other reasons. When the glue gathers to a certain extent, the glue will drip onto the material (especially It is the surface layer material), which affects the performance of disposable absorbent articles and causes quality problems of disposable absorbent articles

Abstract

The invention discloses a detection removing method for a defective disposable absorption article. The method comprises the following steps: the detecting step: installing a drop glue detecting devicebehind a glue sprayer, wherein the drop glue detecting device identifies whether drop glue exists on a continuous material on the way of a production line; and enabling an output end of the drop gluedetecting device to be connected to a controller input end of a waste removing mechanism, while the drop glue detecting device detects the drop glue and a waste product of the drop glue is conveyed to a waste removing port, removing multiple absorption articles containing the waste product by the waste removing mechanism. According to the provided detection removing method for the defective disposable absorption article, whether the drop glue exists on the material can be automatically detected, the waste product can be removed, a defective percentage of the product can be reduced, customer complaints are reduced, and the quality of commodity is improved.

Description

technical field [0001] The invention relates to a method for detecting and rejecting defective disposable absorbent articles used in a production line of disposable absorbent articles. Background technique [0002] Currently, many different types of disposable absorbent articles such as diapers, incontinence pads, sanitary napkins, etc. are widely used on the market. Most of these absorbent articles have a similar structure: a liquid-permeable topsheet, a liquid-impermeable backsheet, and an absorbent core between the liquid-permeable topsheet and the liquid-impermeable backsheet. The absorbent core is capable of receiving and containing liquids, such as body exudates. Absorbent cores are usually made from an intimate blend of fluff pulp fibers and superabsorbent polymers. A liquid-permeable topsheet is used to provide a comfortable and dry feel upon contact with the body, while allowing liquids to pass freely to the underlying absorbent core. The liquid-impermeable backs...
