Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic chopstick packaging machine for packaging disposable chopsticks 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, Chopsticks 53-16358, Jikko Sho 5
O-21020) and a method of forming a chopstick bag at the same time as wrapping chopsticks using long wrapping paper (Japanese Patent Publication No. 15032, No. 52-15513, No. 52-15516, No. 53-3)
7983) 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. Glue is applied to the attached parts, that is, the parts on both sides of the long paper for packaging and the parts that cross the long paper at intervals slightly longer than the length of the chopsticks, and the long paper is folded in half at the center in the longitudinal direction. The system feeds 1 piece between 12 pieces of paper one by one, and the feeding mechanism includes a conveyor system as disclosed in the above-mentioned publications (Japanese Patent Publication No. 52-15032), and a combination of a feeder box and separate loader. Things (Mikoaki! i 3-
37983) exists. When chopsticks are supplied between the folded long pieces of paper and placed inside, the glued areas such as the side edges of the opposing long pieces of paper are pasted with a pressure roll, and the cross-glued parts of the long pieces of paper are cut. Each serving is individually wrapped.

(Problems to be Solved by the Invention) The state of packaging chopsticks using the method described above is as shown in FIG. The glued part C on the upper edge is the part B to be pasted, but in the conventional device described above,
As shown in (a), 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.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides an automatic packaging 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 a layer of water to the long paper in a ladder shape for each length of the long paper, and a glue application mechanism for applying a layer of water to the long paper in a ladder shape for each length of the long paper.
Automatic packaging for chopsticks that is sequentially provided with a folding mechanism that folds chopsticks into a shape, a chopstick supply mechanism that feeds chopsticks between pieces of folded paper for each set, and a packaging mechanism that attaches glued parts and cuts the parts that are pasted for each set. In the mechanism,
The method is characterized in that a long paper for packaging is once folded at the center in the longitudinal direction and a crease is created by folding the long paper at the center in the longitudinal direction and then unfolding the long paper in a process before the glue application mechanism. It is.

Therefore, as shown in Fig. 2, the long packaging paper B is once folded in half and then unfolded again to return it to its original flat state.
If a crease A is made in the center of the long packaging paper and the paper is then wrapped in mA using the conventional method, the non-glued edges become corners as shown in Figure 4 (B). .

(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 a paper supply mechanism, a creasing mechanism, a printing mechanism, a glue coating mechanism, a chopstick supply mechanism, and a packaging mechanism in this order, and these are shown in a simple mechanism diagram. To explain based on FIG. 1, the paper supply mechanism sequentially feeds the long packaging paper B from the roll 1 of the long packaging paper B to the creasing mechanism, and the creasing mechanism is configured to feed the long packaging paper B sequentially from the roll 1 of the long packaging paper B to the creasing mechanism. The long paper B is folded into a U-shape with a folding roll 2 positioned so as to press downward the central part of the long paper for packaging in the longitudinal direction, and then folded in half with a pressure roll 3. A fold D' is formed in the longitudinal center of the long paper B by opening it. The long paper B with the creases is sent to the next printing mechanism, where predetermined characters, figures, etc. are printed using the printing roll 4, and passed through a drying chamber 5 to dry the printed characters, before being applied with the next glue. sent to the organization. The gluing mechanism consists of a gluing roll 6 and a gluing supply roll 7, and the gluing roll 6 has an outer circumference corresponding to the length of the packaging of the table, and also covers both sides of the long paper B and the both sides thereof. It has a coated surface that contacts orthogonal strips of appropriate width. Glue is applied to the coated surface by the glue supply roll 7, and this glue is transferred onto a long sheet of paper. Glue is applied in a ladder shape for each package, and then the long wrapping paper is sent to the chopstick supply mechanism. The chopstick feeding mechanism bends the long paper B for packaging coated with glue into a V-shape with a folding roll 8 and a support rod 9 having a ■-shaped notch, and also bends the long paper B coated with glue into a V-shape. The chopsticks A are dropped one by one between the long wrapping paper 8 which is bent into a V shape. In the packaging mechanism, the chopsticks A are placed inside the long wrapping paper B which is folded into a ■ shape, and the paper is passed through the pressure roll 0 to adhere the glue coated surface, and the paper is perpendicular to the longitudinal direction at the cutting part 11. The glued portion in the direction is cut, and the cut portion is such that the chopsticks A are housed in a bag 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 object of the present invention is an automatic packaging machine that creases the glued edge of the inner valve of a packaging bag, and the presence or absence of a printing mechanism, the specific structure of the chopstick supply mechanism, etc. can be arbitrarily determined, and the above-mentioned implementation is possible. The examples are not limited.

(Effects of the Invention) As described above, the present invention is a conventional continuous automatic packaging machine equipped with a folding mechanism, and chopsticks can be continuously wrapped in a packaging bag that also has creases on the non-glued edges. It can be packaged in
