Description

Detailed Description of the Invention For example, when packaging a large number of paper containers called pack containers, which are used to hold milk or juice, a sheet made of cardboard or the like is used, and the paper containers are packaged in the form of a tray. Because of the busy molding process, a method of packaging a large number of paper containers has been adopted, and the packaging form (accumulation pattern)
For example, a total of 24 pieces, 3 vertically and 8 horizontally (3 x 8),
In some cases, 3 pieces vertically and 9 pieces horizontally ('3 x 9), for a total of 27 pieces, or 3 pieces vertically and 10 pieces horizontally (3 x 10), a total of 30 @, are packaged together.

However, increasing the number of packages larger than this is not practical because the packaged items become heavy, which is inconvenient in terms of transportation (and the packaging machine becomes larger).

On the other hand, making the number of accumulations smaller than in the above case is
It is very difficult to do this in view of the capacity of packaging machines, as the capacity of filling machines has increased.

Despite this situation, for sales reasons, customers are purchasing 12 pieces (3 x 4), 9 x 3 x 3 (3 x 3), or 3 x 3 (3 x 3) pieces, 5 pieces horizontally (3
It is often the case that a packaged item is desired that is packaged in a smaller stacking pattern than a normal stacking pattern, such as a total of 15 pieces in X5).

In this way, the present invention allows a large number of articles to be stored in one place using a tray sheet.
When packaged in a fixed size, for example, in the case of 3 x 8, it can be divided into packages with a smaller accumulation pattern,
In addition, the device used for packaging with a large stacking bag can be used as it is to make it possible to package with a smaller stacking pattern.The packaging method is characterized by one or more cutting lines (c ) to the left and right of the individual tray sheets to form a single tray sheet, and by folding this from each fold line, multiple openings are formed on the left and right sides of the tray sheet through the cutting line (c). The device is characterized by forming a height (d) and storing a group of articles grouped in a predetermined number within each mouth height (dl). To,
A shovel (3) for pushing articles is provided which operates in a direction perpendicular to the driving direction of the conveyor f11, and an article accumulation part (ip) in front of the push shear (3) follows the movement of the articles pushed by the push shear (3). A receiving plate (7) that moves, a partition plate (4) that moves up and down and moves to follow the movement of the article pushed by the pusher (3), and a pusher (3).
) are provided with pushers (8) for pushing out articles that operate in a direction perpendicular to the operating direction of the pushers (8), and on the side of the article accumulation section (p+) in front of the pushers (8), there is a folding flap of the tray sheet. The point is that the device was installed.

An embodiment of the collective packaging method according to the present invention will be described based on the attached drawings.

Figure 8 shows, for example, 3 pieces vertically and 8 pieces horizontally (3x8), a total of 2 pieces.
This shows the most common packaging form for four items (A), in which case a tray sheet (bl) as shown in Figure 9 is used, which is folded from each fold line. and the tray (B1).

FIG. 10 shows the same number of articles (3) packaged by the packaging method of the present invention, in which case a tray sheet (B2) as shown in FIG. 11 is used. This tray sheet (B2) is an individual tray sheet (b'), (
b') are connected to the left and right through one perforation line (c), and this one tray sheet (B2) is bent as shown in Fig. 12 to form one perforation line (C). Two openings (dl) for storing items are formed in one tray on the left and right, and 3 x 4 items (5
), and fold the corresponding backward flap (hl) and outer flap (g) in order to form a tray (B2) as shown in Fig. 10. In this way, 3 x 8 articles can be stored. It is divided into two groups of 3 x 4 items and packaged in one tray, and can be handled as is, or if necessary, divided into two items along the tear line fc) and sold. .

Moreover, FIG. 13 shows the most common packaging form for a total of 27 articles (A), for example, 3 vertically and 9 horizontally (3×9), and in this case, FIG. A tray sheet (B3) as shown is used, which is folded along each fold line and inserted into the tray (B3).

FIG. 15 shows the same number of articles [A] packaged by the packaging method of the present invention, in which case a tray sheet (b4) as shown in FIG. 16 is used. This Tracy), (b4) put 3 x 3 items into 1
2 individual tray sheets (b″) to be packed together
Three trays are connected through two cutting lines (C), and this one tray (b4) is bent as shown in Figure 17 to create three openings for storing items in one tray. height (d) and 3x3 articles (A
), and then the inner flap (h) and outer flap (g) are sequentially bent to form a tray (B, ) as shown in FIG. In this way, the 3 x 9 items are divided into three groups of 3 x 3 items and packaged on one tray, and the items can be handled as a single item, or if necessary, ) can be sold in two or three pieces.

In this way, when a large number of items A) are packaged together, even if the number of items is the same, they are divided into groups and stored in one tray, so small accumulation patterns can be created as needed. The packaging device can be divided into several packages to facilitate handling during transportation, sales, etc. Next, an embodiment of the packaging device according to the present invention will be described with reference to the accompanying drawings. In the example, 3×8 articles are arranged in 3×4
A case will be described in which the products are divided into two groups and packaged on one tray.

As shown in Fig. 1, a pair of left and right vertical belts (2) are intermittently driven at the front end of a conveyor (1) for conveying goods that is constantly driven, and the conveyor belt (2) is intermittently driven.
For example, the articles A), which are loaded and transported, are sent forward in groups of three.

A pusher 13) is provided in front of the vertical carbel) +2+ and i2+, and by operating in a direction perpendicular to the running direction of the conveyor θ), the product A is
) to the front (to the right in Figure 1). At this position (p+ is the article accumulation section, as shown in Figures 2 and 3, there is a partition that is perpendicular to the operating direction of the pusher (3) (left-right direction in Figure 1). A plate (4) and a receiving plate (7) located on the right side of the partition plate (4) and arranged parallel to it push out the accumulated group of articles to the side (downward in Fig. 1). The partition plate (4) is associated with two shillings +51 and +61 as shown in FIGS. (3) side, and gradually retreats due to the exhaust pressure of the shilling (5).Also, due to the operation of the shilling (6), the partition plate (4)
is lying down as shown by the two-dot chain line (4') in FIG.

On the other hand, the receiving plate (7) advances to the pusher (3-in) side by the operation of the cylinder (7a), and the cylinder (7a)
gradually retreats due to exhaust pressure.

To explain the accumulation of articles by the pusher (3), the partition plate (4), and the receiving plate (7) K, as shown in Fig. 7(a), the sealing plate (7a) is activated and the receiving plate (7) is pushed by the pusher (7). −
(3) Advance to the side and wait in this state for the goods to be pushed in. In this case, the piston rond of Schilling (5) is protruding and the partition plate (4) is raised and in a lying state.

The pusher (3) is actuated to push the three articles forward (to the right in Figure 1.2.7). At this time, the receiving plate (7) receives this group of articles so that they do not fall. This action is 4
As shown in Figure 7 (Cl), the
Four sets (total of 12 items) of one set of articles are stacked in front and behind each other. In addition, each time a group of three articles is pushed out by the pusher (3), the receiving plate (7) follows the movement of the articles and retreats one step at a time by the exhaust pressure of the cylinder (7a).

At the moment when 4 sets of 3 items (12 items in total) are stacked in the front and back, the cylinder 16) is actuated and its piston rond protrudes, causing the partition plate to close as shown by the chain line in Fig. 7(c). (4) is lowered and applied to the rear end face of the group of 12 accumulated articles.

Then, the pusher (3) operates again and pushes the group of three articles forward, but there is a partition between the group of 12 articles accumulated last time as shown in Fig. 7(d). Since the plate (4) is inserted, it is separated from the group of items to be accumulated this time, and due to the reciprocating movement of the pusher (3), as shown in Fig. 7 (
As shown in e), on the left side of the partition plate (4),
Two groups of articles will be accumulated.

In addition, each time a set of three items is pushed into the left side of the partition plate (4) by the pusher (3), a shilling (51,
Since both piston rondos in (7a) follow the movement of the article and retreat one step at a time, the partition plate (4) and the receiving plate (7)
follows the movement of the goods and retreats one step at a time.

Thus, as shown in FIG. 1, two groups of 3×4 articles are accumulated in the article accumulation section (pi) with the partition plate (4) in between.

At this moment, the pusher IRI is activated to push out the two groups of accumulated articles to the side. In addition, when the pusher (8) returns to its original position, Schilling - (5), +61° (7a)
are operated, and the partition plate (4) and the receiving plate (7) return to the state shown in FIG. 7(a) and stand by for the next stacking operation.

By repeating this operation, it is possible to accumulate two sets of 3×4 articles across the partition plate (4) and discharge them to the side. In the above case, the partition plate (4) etc. is operated in order to accumulate two groups of 3 x 4 articles on one tray, but the partition plate (4) is moved up and down by changing the switch. By changing the activation timing of the syringe (6) or disabling it altogether, the article accumulation pattern can be easily changed.

A tray sheet folding device as shown in FIGS. 4 to 6 is provided on the side of the article stacking section (p).

By changing the number of IJ and plates, or by making the two left and right bending plates (lla) and bending claws (llb) move up and down independently with separate shillings, and by changing the switch. If each shilling is activated and then deactivated, packaging can be performed using a variety of tray sheets of different shapes.

According to the group packaging apparatus according to the present invention, a gate for storing articles is formed by folding the flap of one tray sheet, and a group of articles sorted by a predetermined number can be assembled in the recess. Since the tray sheet can be automatically stored in the tray sheet, it is possible to efficiently package articles using the tray sheet without reducing the capacity of the packaging machine. Furthermore, by using tray sheets of different shapes, it is possible to package the same number of articles in a smaller accumulation pattern.

Although the packages shown in FIGS. 8, 10, 13, and 15 may be shipped as they are, they are preferably surrounded by a polyethylene film and shrink-wrapped. In this case, it is advisable to make perforations in advance in the film along the perforation line (c) of the tray sheet so that there is no problem when dividing the film into two or more pieces.
