Bonding method for fruit protection bags and fruit protection bags manufactured therefor {Bonding method for fruit protection bags and fruit protection bags manufactured therefor}

The present invention relates to a method of joining a fruit protection bag and a fruit protection bag manufactured thereby. In more detail, when manufacturing a fruit protection bag through a continuous automated process, defects in adhesive application caused by the applied adhesive and defects in the adhesive during the bending and forming process are addressed. It relates to a method of joining fruit protection bags that can solve problems caused by bending and molding defects and at the same time minimize downtime of equipment due to defects, and the fruit protection bags manufactured thereby.

Generally, fruits are exposed to various pesticides, pests and diseases, pollution, excessive heat from the sun, and ultraviolet rays during cultivation. To prevent this, fruit cultivation bags that block fruit from contact with the outside are used.

In the beginning, newspapers and colored bags were mainly used as bags for fruit cultivation, but these bags were not durable and could not prevent damage from rain or hail, and they were easily torn, so they were rarely used in recent years. Various types of improved envelopes are being proposed, and various manufacturing devices are being proposed accordingly.

However, bags for fruit cultivation as described above do not allow smooth drainage when rainwater flows into the bag, or if the drain is expanded for excessive drainage, bees may invade through the drain and cause damage to the fruit. The disadvantage was that it was not easy to bag the fruit.

An invention that solves the above shortcomings is Patent Registration No. 10-2022831 (title of the invention: continuous automated manufacturing method and manufacturing system of pear cultivation bags, and pear cultivation bags manufactured thereby) for which the applicant of the present application is the registrant. there is.

Patent Registration No. 10-2022831 states that fruit protection bags can be manufactured through a continuous automated process, and at the same time, they are molded so that 1 to 2 folds are formed on both sides to facilitate handling depending on the size of the fruit.

The molding process for the folded portion is performed after the adhesive is applied, but there is a problem in that molding defects occur during molding processing for the folded portion due to the adhesive applied in the previous process.

If a defect occurs as described above, the automated equipment must be stopped, then the defective inner and outer paper must be cut and removed before restarting the machine. This will lead to a decrease in productivity and result in significant losses. To solve this problem, In order to do this, problems were pointed out, such as the meaning of a continuous automated manufacturing line disappearing if workers perform manual work.

In order to achieve the above object, the method of joining the fruit protection bag of the present invention and the fruit protection bag manufactured thereby will be described in detail based on the attached drawings as follows.

First, the method of joining the fruit protection bag provided by the present invention includes a roll-shaped outer fabric 10 that performs a light blocking function and a roll-shaped inner fabric (10) that performs a waterproof function as shown in FIG. 1. 20) are supplied to each subsequent process (S100).

Adhesive 80 is first partially applied to the edges of the outer layer fabric 10 and inner layer fabric 20 supplied through the above fabric feeding step (S200), and the outer layer and inner layer fabric to which the adhesive is applied are in contact with each other. In this state, pass between a pair of rollers and laminate the fabric (S300).

A notch 41 is formed on the edge of the laminated fabric 30 to which the adhesive is applied to provide speed and convenience in opening the envelope, and is formed simultaneously in one or more places (S400), and the notch 41 A secondary adhesive is partially applied to the side and lower edges of the inlay fabric 20 among the formed laminated fabric 30 (S500).

As shown in FIG. 4, the secondary adhesive is applied to a portion of the bottom edge and a portion of the right edge of the envelope. In particular, since the portion to which the adhesive is applied to the bottom edge is divided into sections, the envelope is folded along the fold line (44). ), when folded (corresponding to the envelope forming stage), a drainage hole 43 is formed.

The laminated fabric 30 to which the secondary adhesive is applied is transferred through one or more transfer rollers 51 to pass through the inside of the dry chamber 50 so that the applied adhesive is dried (S600) .

As shown in FIG. 2, the laminated fabric 30 that has passed through the inside of the dry chamber 50 is subjected to primary and secondary bending molding so that bent portions 42 are formed on the side of the bag in at least two places. The process continues continuously (S700).

Previously, when the envelope molding process was carried out after applying the secondary adhesive, the undried adhesive would stick between the laminated fabrics or stick to the transfer roller, causing the laminated fabric to be torn or folded and transferred to the post-process, leading to the production of final defective products. In addition, the loss of raw materials was leading to an increase in costs.

However, in the present invention, a complete solution was found by drying the applied adhesive, which was pointed out as a previous problem as described above, for an instant and then proceeding to the envelope molding process. In addition, after applying the first adhesive, the cover fabric 10 and Since even the adhesive that may be excessively applied around the inlay fabric 20 is dried, an easy molding process can be performed.

Also, when the envelope is molded as described above, since it is not yet adhesively fixed, the molded envelope is passed through a pair of heating rollers 60, and the adhesive dried in the dry chamber is melted and the envelope is adhesively fixed. S800).

At this time, a hot air blower 52 that generates heat so that the applied adhesive can be dried while passing through the dry chamber may be installed in the dry chamber 50. In addition, a hot air blower 52 that can generate hot air like a hot air blower may be installed in the dry chamber 50. Alternative electrical appliances may be installed.

In addition, an electric heater 61 capable of dissipating heat is installed on one side of the heating roller 60 or inside the heating roller 60, which can also transfer a heat source to the heating roller 60 in various ways. You can.

After heating and pressing the envelope as described above, a bundling band (70) with wire integrally fixed thereto is supplied and fixed by adhesive so that the top of the envelope can be tied to the outside of the envelope (S900), and the bundling band is tied to one side of the outer side of the envelope. Once fixed, the bags are cut to a standardized size and completed individually (S1000), and the completed bags (40) are loaded and removed by quantity (S1100), thereby completing the production of fruit protection bags.

Meanwhile, as shown in FIG. 1, producer information can be printed on the outer surface of the envelope, and this printing is performed through a printer in any two selected stages from the fabric feeding step (S100) to the envelope loading/unloading step (S1100). A printing step can be inserted between processes so that text is printed on the outside of the envelope.

The fruit protection bag 40 manufactured through the above joining and manufacturing process is easy to use for various agricultural products such as apples, pears, and grapes, and the occurrence of defective products is minimized, thereby improving production efficiency and significantly reducing manufacturing costs. You can get the effect.

Although the embodiments of the present invention have been described, those of ordinary skill in the relevant technical field will be able to invent the present invention by adding, changing, deleting or adding components without departing from the technical spirit of the present invention as set forth in the patent claims. It will be possible to modify and change in various ways, and this will also be included within the scope of the rights of the present invention.
