Description

[Detailed description of the invention] <<Industrial application>> This invention transfers long, slender, rod-shaped items to be packaged, such as dried noodles and spaghetti, in predetermined pitches in batches, and transfers them using a strip-shaped film. This invention relates to an automatic packaging device that performs continuous packaging.

<<Background of the invention>> Conventionally, there is a device as disclosed in Japanese Utility Model Publication No. 17282/1982, which automatically packages a predetermined amount of long, slender, rod-shaped items to be packaged, such as dried noodles or spaghetti. This device had a rectangular gutter for transporting the items to be packaged, so when using one device for dual-purpose packaging by increasing or decreasing the amount of items to be packaged, the side wall of the gutter must be This was extremely difficult due to the mechanical structure, as it was necessary to change the height and width interval and use an appropriate bag-making machine for packaging.

In addition, when replacing the gutter, the article pushing plate that is inscribed in the gutter and transferred must also be replaced (for example, if the dimensions (cross-sectional shape) of the two are different and there is a gap between the article pushing plate and the gutter). (If this occurs, spaghetti, etc. may get into the gap and become impossible to push.) The above work is extremely difficult, so in practice, the gutter is not replaced, and only the bag making device is replaced. As a result, the range of practically possible packaging sizes was extremely narrow. In other words, when packaging is performed by replacing only the bag making device without replacing the gutter, the width of the bag making device must be the same as or slightly larger than the width of the gutter, otherwise the product will not be made from the gutter. Since it is not possible to smoothly feed the packaged items into the bag container, if the amount of the packaged items is reduced and packaged using a gutter of the same width as shown in Figure 14, it is difficult to carry the package. Compared to the one shown in Fig. 13, it becomes extremely flat as shown in Fig. 14, and not only does it have a very bad appearance, but it is also weak in strength, which makes it difficult to carry out subsequent boxing, packaging, etc. In this case, there is a risk that the packaged item may easily break and become a defective product, making it impractical for practical use, and therefore, the packaging size cannot be changed over a wide range.

The present invention was developed in view of the above-mentioned background, and its purpose is to eliminate the need to replace the packaged material transfer gutter and the product pushing plate each time, even if the amount of packaged products changes. To provide an automatic packaging device capable of efficiently carrying out dual-purpose packaging in a very wide range by simply replacing only a bag-making device, and also capable of manufacturing packages in a form suitable for various packaging sizes.

<Means for Solving the Problems> In order to achieve the above-mentioned purpose, the automatic packaging device for long and thin rod-shaped packages such as dried noodles according to the present invention has the following features:
The cross sections of the packaged material transfer gutter and the bag making device are formed into a V-shape having substantially the same angle, and
The article transfer gutter and the bag making device are arranged in series so that the inner bottom surfaces of the V-shaped cross sections are located on substantially the same straight line along the transfer direction of the article and at approximately the same level.

《Operation》 If the amount of items to be packaged increases or decreases, replace the bag making machine with a bag making machine (of a different height) that corresponds to the change.
At this time, since the bag making machine and the packaged material transfer gutter have a V-shaped cross section with substantially the same angle, even if the amount of packaged material to be packaged increases or decreases, the packaged material transfer gutter and There is little increase or decrease in the height of the packaged object when it passes through the bag-making machine, and the cross-sectional shapes of the packaged objects are almost similar, making it possible to produce good-looking packages (not extremely flat). Ru.

<<Example>> Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

A well-known center sealing device 4 seals and seals the cylindrical body F' to form a cylindrical body F' at the front and rear sides of the packaged article storage section 5 in the transverse direction with respect to the traveling direction. ' is a well-known top seal cutting device, and 6 is a gutter for transferring the packaged material, and is formed in a V-shaped cross section.

Further, 8 is an article pushing plate that moves at a constant speed in each predetermined pitch within the packaged article transfer gutter 6,
It is formed to have the same cross section as the packaged material transfer gutter 6, that is, to have a V-shape, and is adapted to move in contact with the inner surface of the packaged material transfer gutter 6. Reference numeral 9 denotes a shaft to which the article pushing plate 8 is attached, and an endless chain 1 stretched along the article conveying gutter 6.
A mounting member 12 having a molded cross section is integrally fixed to one side of the upper part of an article transport plate mounting board 11 (hereinafter referred to as mounting board) which is mounted at regular pitches on the shaft 9. A rectangular sliding member 14 is fitted into the recess 13 of the mounting member 12 in a sideways state, and a lever 15 is fixed substantially perpendicular to the sliding member 14.
16 and 17 are upper and lower guide members, which are parallel to the endless chain 10 so that the lower guide member 16 is in contact with the lower surface of the mounting member 12, and the upper guide member 17 is in contact with the upper surface of the sliding member 14. and is fixed at a predetermined location on the machine frame 18 by appropriate means. 19 is the packaged material transfer gutter 6
The lever 15 is a cam plate for reversing the article pushing plate fixed to a predetermined position of the machine frame 18 on the front end side of the machine frame 18, and the lever 15 is activated when the article pushing plate 8 sends the article to be packaged a into the bag making machine 2. The article conveying and pushing plate reversing cam plate 1

Further, the upper and lower guide members 16 and 17 are adapted to release the guides of the mounting member 12 and the sliding member 14 at a position where the lever 15 abuts against the cam plate 19 for reversing the article transport plate. 20, 20' are sprockets on which the endless chain 10 is stretched, and are driven by a driving force from the automatic packaging machine 1 side, although not shown. In addition, 2
Reference numeral 1 denotes a well-known automatic weighing machine for packaged articles, and 22 denotes a well-known temporary pool hopper, which drops the packaged articles a weighed to a predetermined amount into the packaged article transfer gutter 6 at a predetermined timing.

Here, in the present invention, the above-mentioned bag making device 2 is formed to have a V-shaped cross section, similar to the packaged article transfer gutter 6. The angles formed by both side surfaces are substantially the same as those of the bag making device 2 and the packaged material transfer gutter 6. Further, the bag making device 2 and the packaged article transfer gutter 6 are arranged in series so that the inner bottom surfaces 7' and 7 of the V-shaped cross section are substantially on the same straight line and at substantially the same level.

In addition, a plurality of bag making devices having the same angles on both sides as described above and different heights are prepared, and can be replaced as appropriate depending on the amount of the packaged items a to be packaged.

Next, to explain the operation of the above-mentioned embodiment, when packaging a packaged product, a long and thin rod-shaped packaged product a such as dried noodles or spaghetti weighed to a predetermined amount by the automatic weighing machine 21 is temporarily removed from the pool hopper 22. The packaged items are dropped into the transfer gutter 6 in a bundled state. Then, the packaged object a is the third
As shown in the figure, the articles are transferred to the automatic packaging machine 1 in predetermined pitches by the article pushing plate 8, and are fed into the bag making machine 2 disposed at the tip of the article transfer gutter 6 as shown in the figure. , the strip film F produced by the bag making device 2 and the center sealing device 3 is inserted into the cylindrical body F', and as shown in the first figure, the top seal cutting device 4 cuts the packaged material into the packaged article storage section 5. The front and rear parts are sealed and cut in a direction transverse to the direction of travel to produce a package a'.

When the amount of the packaged items a increases or decreases, the bag making device 2 (of a different height) is replaced accordingly. At this time, as mentioned above, the bag making machine 2
Since the angle formed by the side surface of the packaged article a and that of the packaged article transfer gutter 6 are substantially the same, that is, have substantially the same cross-sectional shape, the amount of increase in the height of the packaged body relative to the increase in the amount of the packaged article a is small, and the packaged article is not easily packaged. The cross-sectional shape of the packaging body a' is also substantially similar (see FIGS. 11 and 12), and a good-looking (not extremely flat) packaging body a' is manufactured.

<<Effect of the invention>> As described above, according to the invention, the cross sections of the packaged material transfer gutter and the bag making machine are formed into a V-shape having approximately the same angle, and the inner bottom surface of each V-shaped cross section is covered. Since the packaged material transfer gutter and the bag making device are arranged in series so that they are located on substantially the same straight line along the packaged material transport direction and at substantially the same level, the amount of packaged material can be increased. Even when packaging is to be carried out with a reduced number of items, there is no need to replace the article transport plate or replace each part as in the past, and the bag making machine is simply adjusted to the size ( height)
Packaging can be done simply by replacing it with a new one.

As a result, the workability is very good and packaging can be performed with high efficiency.

Moreover, it is possible to obtain a package with a good packaging form (appearance) that always maintains a balance between height and width as the amount of items to be packaged increases or decreases. It was possible to expand it to a large extent.
