Description

Method for manufacturing wearing article

Technical Field

The invention belongs to the field of sanitary products, and particularly relates to a method for manufacturing a wearing article, which has excellent elasticity at the waistline part and is provided with a waist tape, so that the wearing article is convenient and comfortable to wear.

Background

Along with the development of society, the living standard of people is continuously improved, and disposable hygienic products are widely used. The prior products containing elastic waistline can be roughly divided into paper diapers and pull-ups, the prior paper diaper products are usually added with elastic components between two layers of non-elastic sheets and waist tapes on the left and right sides of the non-elastic sheets, and the elastic components of the product are usually discontinuous or the quantity of the elastic components is limited from one side to the other side, so that the elasticity of the waistline is weak; the existing pull-up diaper products have continuous elastic members in the transverse direction, but are cumbersome to wear. In view of this, I have designed a kind of absorbent article with excellent elasticity on the whole waistline, this kind of wearing article has the advantage that the waist of the pull-up diaper is comfortable well concurrently, have the advantage that the disposable diaper is convenient to use again, contain many elastic components that extend from left side to right side in the waistline, and the left and right sides in the waistline is equipped with the waist and pastes, its product structure can refer to CN104905911A that applicant applied earlier.

However, the above products are difficult to realize in-line mass production, and the design difficulty lies in the processing of the elastic waistline and how to arrange the elastic waistline on the absorption body. For example, the elastic waistline needs to have a large tension when being compounded on the line or initially conveyed; in the conveying process, the procedures of arc cutting, magic waist tape compounding and the like are required, and the stretching multiple of the elastic waistline in the procedures is required to be small enough, otherwise the defect that the product is not attached to the skin of a user is caused; in addition, when the elastic waist band is combined with the absorbent main body, it is required that the elastic waist band must have a sufficiently large stretch ratio to be disposed on the absorbent main body.

In summary, how to adjust the tension requirements of each stage in the process of manufacturing the elastic waistline to realize the processing of the elastic waistline and the combination with the absorption body has become a problem to be solved in the art.

Disclosure of Invention

In order to overcome the problems, the invention provides a method for manufacturing a wearing article which is convenient to wear and has excellent elasticity, thereby realizing the streamlined mass production of the new products, greatly improving the manufacturing efficiency and reducing the production cost.

The technical scheme adopted by the invention for solving the problems is as follows: a method for manufacturing a wearing article for combining an elastic waist band with an absorbent main body to form a disposable wearing article, wherein a moving direction of a belt-like elastic sheet is taken as a flow direction, and a direction perpendicular to the flow direction is taken as a width direction, comprising the steps of: a step of conveying a band-shaped elastic sheet which can stretch and contract in a flow path direction while stretching the elastic sheet in the flow path direction; releasing the tension of the elastic sheet material in the flow direction to make the tension of the elastic sheet material zero or less than the tension in the step I, preferably conveying the elastic sheet material without tension, namely making the tension zero; processing the elastic sheet and cutting the elastic sheet according to a specified length; rotating the cut elastic sheet by 90 degrees and expanding the elastic sheet along the width direction vertical to the flow direction to ensure that the elastic sheet is in a stretched state again to form the elastic waistline; fifthly, arranging the elastic waistline on the absorption body at intervals. The "belt-like elastic sheet" in the foregoing step (i) may be formed by adding a plurality of elastic bodies between two sheets on a thread, or may be a composite sheet prepared under a thread and having a plurality of elastic bodies added thereto.

By adopting the technical scheme, the tension of the elastic sheet is released in advance before the elastic sheet is processed, so that the tension is zero or less than that in the step I, the quality of arc cutting and waist applying in the step III is ensured, an arc-shaped contour matched with the leg shape of a user is formed on the elastic sheet, and the wearing comfort of the user is improved. At the same time, the elastic sheet is turned after cutting and is widened in the width direction perpendicular to the flow direction, so that the stretch ratio of the elastic sheet is increased and finally arranged on the absorption body, thereby completing composite molding of the wearing article.

When the side of the absorption main body far away from the skin contact is made of the liquid-impermeable material, the process of folding, cutting and folding the wearing article is also included after the fifth step. When the absorption body itself has no leak-proof property, the process of arranging the liquid-tight outer packaging sheet on the lower layer of the absorption body is also included after the fifth step, and then the wearing article is wrapped, cut and folded. In other words, whether or not the "liquid-impermeable outer sheet" is provided depends mainly on whether or not the absorbent main body is leakproof, and therefore the technical solution recited in claim 10 is to be understood to include both cases. In addition, the front and back sequence of the three procedures of wrapping and folding, cutting and folding the two wings is not particularly limited, and can be reasonably adjusted according to the requirements during use.

As a further improvement of the present invention, a step of cutting or fusing a local elastic body on the elastic sheet is further included between the first step and the second step, and the purpose here is to prevent the connecting part of the absorption body and the elastic sheet from being excessively wrinkled under the elastic action of the elastic sheet, which affects comfort and prevents products from easily leaking. Furthermore, the cutter for cutting off the local elastic body on the elastic sheet material is provided with two cutting edges which are arranged at intervals, an elastic body cutting area is cut on the elastic sheet material by the two cutting edges, and the glue type width in the area is changed by changing the intermittent glue applying mode of the glue gun. In addition, in the process that the elastic sheet is released to be zero or less than the tension value in the initial state from the moment that tension exists at the beginning in the step II, in order to enable the whole conversion process to be more stable, firstly, the elastic sheet passes through a non-negative pressure conveying system by arranging a pair of driving rollers with speed difference, and then passes through a negative pressure conveying system, preferably, a material pressing system for pressing the elastic sheet to prevent the elastic sheet from deviating is further arranged between the non-negative pressure conveying system and the negative pressure conveying system, and the device can effectively help the elastic sheet to be stable and not deformed in the whole conversion process.

Specifically, the processing of the elastic sheet in the third step includes the steps of performing arc cutting on one side or both sides of the elastic sheet in the width direction, recovering waste materials generated by the arc cutting, and compounding the waist tape on the elastic sheet at intervals along the flow direction of the elastic sheet. Of course, the stations of the above processes may also be adjusted accordingly, such as first compounding the waist tape, then arc cutting, and recycling the waste, and the method is similar to the above method, and will not be described herein again. Furthermore, the cutting position in the third step is the middle part of the waist tape along the flow direction, and the shape of the cutting edge of the cutter cutting the elastic sheet material according to the specified length is linear or S-shaped. It is worth mentioning that both the above described arc cutting and the application of the waist panel require the elastic sheet to maintain a relatively small or even zero stretch ratio. For the arc cutting, since the cut arc-shaped contour corresponds directly to the outside area below the waist and above the thighs, if the arc cutting process is performed with the elastic sheet under a large stretching ratio, the elastic sheet will present an irregular or even locally piled contour when retracted, which affects the appearance and comfort of the product; for waist tape application, if the elastic sheet is applied at a larger stretching ratio, the waist tape is easy to fall off under the action of the contraction force of the elastic sheet at the composite position. In summary, a step of releasing the tension is required before the step (c).

In addition, the step of directly determining whether the waist circumference formed by cutting the elastic sheet material according to the specified length is a single product or two products arranged oppositely according to the arc cutting position on one side or two sides of the elastic sheet material in the width direction. Wherein, for forming a single product, the local elastic body cutter and the arc-shaped cutter are both arranged at one side of the width direction, the waist tape is correspondingly provided with a group, and is divided into two parts through the cutter blade, and is cut into a left waist tape of a previous product and a right waist tape of a next product, of course, the waist tape can also be divided into two parts in advance and is respectively applied to corresponding positions of the products, at the moment, the central distance between two adjacent elastic waistlines is equal to the length of the absorption main body, and the absorption main bodies compounded with the elastic waistlines are sequentially arranged in the same direction in the flow direction in the mode. For forming two products which are arranged oppositely, the local elastic body cutter and the arc-shaped cutter respectively comprise two groups and are correspondingly arranged at two sides in the width direction, the waist tape is correspondingly applied with two groups, the products at one side and the other side in the width direction are respectively added, the two products are arranged oppositely in the width direction at the front edge of the turning and expanding, the two products are arranged oppositely in the flow direction after turning, the central distance between two adjacent elastic waistlines in the step five is twice of the length of the absorption main body, the products in the flow direction after compounding are approximately arranged in a mode of head to head and tail to tail, and a forward and reverse laminating device can be omitted in the subsequent links after cutting and folding, so that the product packaging is more convenient, and the manufacturing cost is further reduced.

Furthermore, the process of turning and expanding the cut elastic sheet in the step (iv) may be performed simultaneously on one apparatus or may be performed in steps, wherein the process performed on one apparatus is the best process for further improving the production efficiency. The device for realizing the turning and the expanding into a whole comprises a stator part and at least one group of rotor parts which can rotate around the stator part, wherein the stator part is cylindrical, and the peripheral surface of the stator part is provided with a direction-changing cam groove; the mover member includes a turning member and a width expanding member. The steering component comprises a steering cam guider and a steering plate fixed with the steering cam guider, and the expanding component is provided with an expanding plate capable of moving along the circumferential surface of the stator component and two elastic material holding components; the width expanding plate is provided with a width expanding cam groove, one side of each elastic material retaining part, which is close to the steering plate, is provided with a width expanding cam guider which penetrates through the steering plate and can move along the width expanding cam groove, and the direction changing cam guider penetrates through the width expanding plate and can move along the direction changing cam groove of the stator part. In order to ensure that the movement of the two elastic material holding parts is more stable, as a further improvement of the invention, a guide groove matched with the width expanding cam guide is also arranged on the steering plate. The expanding cam guide reciprocates linearly along the guide groove while the two elastic material holding members perform the expanding operation. Furthermore, one side of the elastic material holding part close to the steering plate is provided with a group of grooves, and the steering plate is correspondingly provided with bulges matched with the grooves. In addition, the speed change mechanism in the above device can be realized by a servo motor or a mechanical cam, both of which are in the prior art and will not be described herein. Similarly, a protrusion may be disposed on one side of the elastic material holding member close to the steering plate, and a groove may be correspondingly disposed on the steering plate. The device avoids the defects caused by the switching of the elastic material between different holding parts through function integration, improves the stability of the elastic material in the production process, and has more compact structure and high production efficiency. In addition, when the step-by-step operation is completed, the operation can be realized by matching a variable-speed expanding device and a steering device, a variable-speed part in the variable-speed expanding auxiliary device can be driven by a mechanical mode or a servo motor, the expanding part can be formed by arranging symmetrically-arranged cam grooves on a cam, and an expanding plate is arranged in the cam grooves through a cam guider. There are, of course, many ways to implement the above-described functions, and not limited to the specific arrangements set forth above.

The elastic waist band may be disposed on the absorbent body at a position close to the skin-contacting side, at a position away from the skin-contacting side, or between the absorbent body and the outer sheet.

Compared with the prior art, the invention has the following advantages: the invention firstly provides tension-free or low-tension conveying in the industry, and realizes the flow line batch production of the wearing articles in the background technology by controlling the stretching multiple of the elastic sheets in the conveying process in a sectional manner, thereby greatly improving the production efficiency, shortening the process flow and saving the space and time.
