An embodiment of the present invention has the above-mentioned structure,
Next, a case where the package 5 is packed in a box using the above device will be described.

First, a plurality of bell peppers are packed in a bag by the packing machine, and the packing body 5 is positioned by the positioning plate 8 of the conveying device 1.
It is sequentially supplied in the meantime and is conveyed to one end of the belt 6. The package 5 that has reached one end is dropped and held in an upright state between the standing plates 15 of the pitch conveyor 16 that intermittently rotates the aligning device 13.

In this way, 10 packages 5 are provided on each standing plate.
When supplied between 15, the sensor (not shown) detects this and the pitch conveyor 16 stops. After that, the pusher 25 is operated by the lifting cylinder 28 to move the pitch conveyor 16
Of the sliding cylinder 33, and the pusher 25 of the sliding cylinder 33 is located on the pitch conveyor 16 side.
It is moved so as to cross (see FIG. 8A). At this time, since the pusher 25 moves between the standing plates 15 of the pitch conveyor 16, the pushers 25 scrape out the packages 5 at the same time in rows.
While pushing it out on the mounting table 30 of the width-shifting device 29, after that,
Even if it goes up, it returns to the original standby position.

Next, the pressing plates 31 approach each other, and the widths of the packages 5 are narrowed so as to be narrowed. Behind the width-adjusted packaging body 5, the ejection plate 40 of the supply device 38 is lowered by an elevating cylinder 42, and further, the sliding cylinder 43 is a slide body.
In order to move 41 forward, the package 5 on the mounting table 30 is transferred onto the tray 39 (see FIG. 8B).

By further repeating the above-mentioned steps, the succeeding package 5 is also transferred onto the tray 39 by the projecting plate 40, but the package 5 in the second row following the projecting plate 40 is transferred. When pressing, the second-row packaging body 5 pushes out the first-row packaging body 5, and the tray 39
A total of 20 packages 5 in two rows are placed on the top (see FIGS. 9A and 9B).

In this way, the two rows of the packaging bodies 5 are placed on the tray 39.
When the tray is placed, the lifting cylinder 48 raises the tray 39, and the sliding cylinder 47 advances the raised tray 39 to above the temporary storage box 50 (see FIG. 10A).

On the other hand, the lifting table 54 in the temporary storage box 50 is
At the uppermost position, the shutter plate 58 is lowered. In this state, the tray 39 is the lifting table.
When the pushing plate 60 descends from the upper limit standby position when it comes down to approach or contact with 54, it moves forward and pushes the bulging part at the rear of the packaging body 5, so that the packaging body 5 is completely stored in the temporary storage box 50. Make sure to enter it (see Figure 10 (b)).

Next, as described above, the packaging body 5 in the two rows is surrounded by the temporary storage box 50 and the pushing plate 60, and then only the tray 39 is retracted and pulled out (FIG. 11).
(B)). Further, after the shutter plate 58 is raised so that the package 5 does not protrude from the temporary storage box 50, the pushing plate 60 is raised and returned to the original standby position.

The above process is the operation of storing the first-stage package 5 in the temporary storage box 50, and the same operation is repeated in the case of the second and third stages. Figure 11
(The tray 39 on which the second-stage packaging body 5 is placed as shown in (b)
After being transferred above the first-stage packaging body 5,
When the tray 39 descends as shown in (a), the tray
Corresponding to 39, the lifting table 54 and the shutter plate 58 in the temporary storage box 50 also descend at the same time. When the tray 39 is lowered, the packings 5 arranged in the first stage on the lower surface of the tray 39 are arranged.
Is preferably performed while pressing from above. Note that FIG.
When the third-stage packaging body 5 is similarly stored in the temporary storage box 50 as shown in (b), the temporary storage box elevating cylinder 77 raises the temporary storage box 50.

On the other hand, the box 81 is conveyed above the temporary storage box 50 by the box supply device 88 so as to be opened downward, and then the box 81 descends into the temporary storage box 50. Be fitted. At this time, since the temporary storage box 50 is made of a thin metal plate, the storage space of the box 81 is hardly reduced. Further, the lock lever 90 swings and is closed, and the lock lever 90 holds the bottom surface of the box 81 (Fig.
See 13).

Next, since the rack cylinder 74 operates to move the rack 75, the pinion 72 rotates and the temporary storage box
The reference numeral 50 indicates 18 around the rotary shaft 70 with the box 81 fitted.
Reverses 0 ° and descends. The temporary storage box 50 may be lowered while the temporary storage box 50 is inverted.

When the temporary storage box 50 and the box body 81 are lowered, the lock lever 90 is released and the temporary storage box 50 is raised, so that the box body 81 is separated from the temporary storage box 50 together with the packaging body 5. Is placed on the discharging roller conveyor device 93 and is carried out by the conveyor device 93, and the lid of the box body 81 is appropriately closed. In addition, when the box 81 is removed from the temporary storage box 50, it is preferable to lower the elevating table 54 and push out the package 5 so that the package 5 is aligned with the box 81 and is reliably stored. .

Further, the raised temporary storage box 50 is inverted to the original position by the reversing device 68, the next first-stage packaging 5 is stored in the temporary storage box 50, and similar operations are sequentially performed. . still,
The process of temporarily storing the first to third-stage packaging bodies 5 in the temporary storage box 50 and further storing them in the box body 81 is shown in FIG.
~ (F).

The present invention is not limited to the above-described embodiment. For example, in the above-mentioned embodiment, the packaging bodies 5 each having 10 pieces in one row are arranged in two rows, and the packaging bodies 5 are further stored in three rows to make a total of 60 pieces. Although the case where the package 5 is stored in the box 81 has been illustrated, the number of the package 5 to be stored is not limited to this.

Further, although two rows of the packaging bodies 5 are placed on the tray 39, they may be placed in one row or in three or more rows. Moreover, the items to be stored may be those in which sweets such as sweets and snacks other than fruits and vegetables such as bell peppers are packaged, and are not particularly limited, but a packaged body in which a plurality of items are packed is particularly preferable. .

[0040]

As described above, according to the present invention, a plurality of items to be stored are placed on a tray, and the items to be stored are temporarily stored in the temporary storage box from above by the tray. After fitting the inverted box body having the opening on the above from above,
Since the temporary storage box and the box body are separated so that the box body and the temporary storage box are integrally inverted and the storage object is stored in the box body, the storage object is packaged with a plurality of bell peppers in a bag. Even in the case of such a package, the package can be stored in a box in a state where the packages are automatically aligned, and the rationalization of work and the improvement of productivity due to labor saving can be achieved.

Further, in the box packing device for the items to be stored,
In the temporary storage box, an elevating table on which the objects to be stored are placed is provided so as to be able to store the objects to be stored in a plurality of stages so that the objects can be stopped in a plurality of stages at a predetermined position. If it is also provided so as to be able to move up and down, it is possible to store the packages in multiple stages in the temporary storage box. As a result, by temporarily storing the package in the temporary storage box, there is an advantage that the package can be easily stored in a plurality of stages in a box such as a cardboard box.

Further, since the temporary storage box has a structure in which the packaging body in the temporary storage box is accommodated in the box body by reversing the temporary storage box with the reversing device, the temporary storage box itself has no structure. It is not necessary to incorporate a device for housing the package in the box.
Therefore, the storage space of the temporary storage box can be made as large as possible, and it is not necessary to make the box body particularly large in order to store the temporary storage box in the box body, and the packages arranged in the temporary storage box are cluttered. There is an advantage that it can be stored in the box as it is without becoming.

Moreover, since it is not necessary to incorporate a device for accommodating the package in the temporary storage box itself, the device can be simplified and the method of the present invention can be easily achieved. .
