Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic chopstick packaging machine for packaging books and other items in paper bags.

(Prior art) Chopsticks are packaged using a method of inserting each chopstick into a cylindrical bag (Tokukoku Sho 52 19150, Sho 53-16358, Jikko Sho 5
0 21020), and a method of forming seven bags at the same time as wrapping chopsticks using long wrapping paper (Japanese Patent Publication No. 52-15032, Japanese Publication No. 15513. No. 52-1551 (i, No. 5)
3-37983) exists.

The present invention relates to the latter method.

To briefly explain the conventional device for wrapping chopsticks with long wrapping paper, long sheets of paper are sequentially fed out from a roll of long wrapping paper, predetermined printing is applied to the long wrapping paper, and then glue is applied. Apply glue to the attached parts, that is, the parts on both sides of the long paper for packaging and the places where the long paper is crossed at intervals slightly longer than the length of the chopsticks, and then fold the long paper in half at the center in the longitudinal direction and bend it in a prayer. The chopsticks are fed one by one between the sheets of paper, and the feeding mechanism uses a conveyor (as disclosed in the above-mentioned publications).
15032), a combination of a feeder box and a separate loader (Japanese Publication Act 53-379)
83) exists. When the chopsticks are supplied between the folded long pieces of paper and placed inside, the glued areas such as the side lines of the opposing long pieces of paper are pasted with a pressure roll, and when the glued parts across the long pieces of paper are cut, the chopsticks are placed in one place. Each meal is wrapped.

(Problems to be Solved by the Invention) When chopsticks are packaged using the method described above, as shown in FIG. The glued portion C on the upper edge is pasted, but in the conventional device described above,
As shown in f), the non-glued edges are rounded, spoiling the image of a chopstick bag. That is, the original chopstick bag has a flat cylindrical shape with sharp corners on both sides, but the above-mentioned packaging bag does not have one edge with a corner.

(Measures for Solving the Problems Vi) In order to solve the above-mentioned problems, the present invention provides an automatic wrapping machine for chopsticks that is equipped with a mechanism for creating creases in long wrapping paper. That is, the chopstick automatic packaging machine according to the present invention includes a feeding mechanism for long and thin packaging paper, a glue application mechanism for applying glue to the long paper in a ladder shape for each length of paper, and a folding roll to apply glue to the long paper in the longitudinal direction. A folding mechanism that bends the chopsticks into a U-shape at the center of the direction, a chopstick supply mechanism that supplies chopsticks between folded sheets for each meal, and a packaging mechanism that attaches the glued area and cuts the pasted area for each set are sequentially provided. In this automatic chopstick packaging mechanism, a clamping gap is formed at the folded portion of the long paper immediately after the folding roll of the folding mechanism, and a crease is formed at the folded portion of the long paper. be.

Therefore, immediately after the long paper is folded into a U shape, the folded portion passes through the clamping gap and is folded into a ■ shape to form a crease I. After that, the paper A is packaged using the conventional method. Then, as shown in FIG. 5(B), the non-glued edge becomes a corner.

(Example) Next, embodiments of the present invention will be described based on the drawings.

The automatic chopstick packaging machine according to the present invention is provided with 11 units including a paper supply mechanism, a printing mechanism, a glue application mechanism, a folding and creasing mechanism, a paper supply mechanism, and a packaging mechanism. The long paper for packaging is sent sequentially from roll 1 of long paper B to a printing mechanism, and the printing mechanism uses a printing roll 2 to print predetermined characters, figures, etc., and passes it through a drying chamber 3 to print the printed characters. etc., and then sent to the next glue application mechanism. The glue application mechanism consists of a glue roll 4 and a glue supply roll 5.
has an outer periphery corresponding to the length of the packaged meal, and has an application surface in contact with both sides of the long paper B and a band-like part of an appropriate width that extends perpendicularly to both sides, and has a coating surface that is in contact with both sides of the long paper B and a band-shaped part of an appropriate width that extends orthogonally to both sides. Glue is applied to the application surface by roll 5, and this glue is transferred onto a long sheet of paper. Glue is applied to the long sheet of paper B in the form of a ladder for each package of chopsticks and a meal. The long wrapping paper is fed to a folding and creasing mechanism. The folding mechanism folds the long paper B coated with glue in half, and a flat vertical folding roll 7 is positioned on the center line of the long paper that advances next to the horizontal tension roll 6. The long paper B is folded in half into a shape, and a gap forming part 8 is provided in front of the folding roll 7 by bringing two members close together, and a gap a of the gap forming part 8 is provided.
It is made by passing a long sheet of paper B which has been folded in a manner so as to pass through the folded part, and forming a crease in the folded part. The V-shaped long paper B, which has been folded in half with a crease, is sequentially sent to the next chopstick supply mechanism and then to the packaging mechanism.The chopstick supply mechanism folds the long paper B into a V shape in accordance with the advancing speed of the long paper B. It is made by dropping chopsticks A one by one between 8 pieces of bent long wrapping paper. In the packaging mechanism, chopsticks A are placed inside a long wrapping paper B that is bent in a V shape, and the chopsticks A are passed through a pressure roll 9 to adhere the glued surface, and then cut in a direction perpendicular to the longitudinal direction at a cutting section 10. The glued portion of the bag is cut, and the cut portion is placed in a bag made of paper B made of long packaging paper B, as shown in FIG. Therefore, when each mechanism is continuously and interlocked with each other as the long packaging paper B advances, automatic packaging is continuously performed using a packaging bag having creases formed on the non-glued edges.

The purpose of the present invention is to provide an automatic packaging machine for forming creases on the inner edges of packaging bags, and the presence or absence of a printing mechanism, the specific structure of the chopstick feeding mechanism, etc. can be determined as desired. It is not limited to the examples.

(Effects of the Invention) As described above, the present invention equips a conventional continuous automatic packaging machine with a creasing mechanism, and continuously wraps potatoes in packaging bags that also have creases on the non-glued edges. It was made.
