Each set of support rails (402) is stopped at the loading position (a), loading position (a) and delivery position (al) by intermittent feeding of the chain. It is arranged below so as to be orthogonal to this feeding direction, and the input position (b) is arranged directly below the seventh conveyor 07).

A support body (403) is disposed below the input position (bl). This support body (403) is connected to the intermittent feeding chain (401 ) (401), between the pair of support rails (402) (402), and further between the bent short side flaps (22b) (22b), and rises above the cardboard box (2). Accordingly, the opening/closing conveyor (302) (303) of the seventh conveyor 0η
When the bag i1m is opened, the items to be packaged falling naturally are stopped. Then, the support body (403) is gradually lowered by the elevating means, and the article to be packaged is placed on the bent short side flap (22b) (22b) without applying any impact. Furthermore, a support (403)
Only the lower part moves downward and escapes to the lower part of the lower conveyor, thereby completing the operation at the input position iZ (b).

Next, based on FIG. 29, the placement of the cardboard box at the placement position (a) and the delivery at the delivery position (C) will be briefly explained.

A pair of fixed rails (4
10) (410) is arranged. Fixed rail (41

A belt conveyor (423) is placed on the right side, where the upper flaps of the corrugated pole box (2) are folded in, and packing tape is applied to the top and bottom surfaces using a device (430). is completed. Various known devices can be used for folding the flap and applying adhesive tape, or it can also be done manually.

(Other examples of frame body) Next, another embodiment of the frame will be described based on FIG. 30.

The previous frame body 1u had a bottom lid that opened in a double-door shape, but the frame body (Sol) of this embodiment has a bottom lid (502).
(502) slides left and right to open, bottom lid (502)
) (502) has a distal end protruding outside in the closed state, and a latching portion (502) that is bent upward at the distal end.
3) is provided. Further, arm portions (504) (504) are provided protruding from both left and right sides of the frame (501).

In order to transfer this frame (501), the seventh conveyor 07
) is changed as follows. That is, instead of opening/closing hair, it is arranged on both sides of the frame (501), and the arms (501) are connected from below.
04) Guide rail (505) that supports (504)
(50-5) and push the supported frame (501) (
or by a hydraulic cylinder (
(not shown). Further, the object to be packaged inside the frame is dropped by pulling out the bottom cover (502) (502). This withdrawal can be carried out by providing a retaining part (507) at the tip of the rond of the fluid cylinder (506) and engaging the retaining part (507) with the retaining part (503) of the bottom cover. The frame body (501) supports the support body (403) for controlling the falling speed, and the bottom M (503)
This is advantageous in that the shock of falling can be reduced.

(Second packaging method) When the packaging body is a self-supporting plastic container, the use of a frame becomes unnecessary. To briefly explain this using FIG. 1, the package is placed directly into the environmentally friendly chamber along the transfer path without using the frame.

The package passes directly from the starting end position (1) of the first conveyor (11) to the bag insertion position (2) of the second conveyor.

Next, all the automatic opening/closing doors for the outward route open and the second conveyor 0
21 to the third conveyor 0, and stops at the - time stop position (3). - The package stopped at the time stop position (3) is transferred to the fourth conveyor 0 by the extrusion device (b).
4) It is sent to the upper filling position (4) and stops, and the object to be packaged is filled into the package. The filled package is sent from the fifth conveyor 00 to the sixth conveyor (16), and its mouth is closed. Next, the package goes out of the sterilization room (A) through the opened automatic return door (to), is dropped at the drop position (6) on the seventh conveyor 07), and is dropped into a cardboard box (company). ). The cardboard box @ is then sealed at the packing position (7). Note that since the frame 1111 is not used, the ninth conveyor side and the bag insertion device are not required.

(Explanation of Modifications) The packaging body may be changed to other packaging bodies such as a sheet-like body in addition to the bag body.

In the embodiment, the object to be packaged in one bag is placed in one package, but two or more packaging methods may be used in one package.

If the object to be packaged is a solid or a highly viscous fluid, it is desirable that the cross-sectional shape of the frame is approximately the same as, or smaller than, the cross-sectional shape of the package such as a cardboard box. This allows for smooth transfer of the packaged items. In addition, if the fluidity of the packaged material is high,
Even if the frame is larger, its fluidity allows it to be transferred to the package.

In addition to the box-like frame, the frame can be changed to a frame made of wire or the like or a basket made of net or the like.

In the embodiment, the bottom of the frame was opened to let the packaged items fall, but the packaged items may be taken out from the side or top.

The package may be a cardboard box or other containers such as boxes or cans made of other materials.

The transfer path may be U-shaped as in the embodiment, or may be linear. Furthermore, the transfer path may be carried in and out of the environmentally friendly room by reciprocating along the same transfer path. .

<Effects of the Invention> In the first packaging method of the present invention, since no packaging containers are brought in, germs and dust from packaging containers such as cardboard boxes do not contaminate the environment-friendly room. Then, a flexible packaging body such as a bag is attached to the frame body either outside or inside the environmentally friendly chamber, and
Since the items to be packaged are stored in a flexible packaging body such as a bag in a room with a good environment, the items to be packaged can be efficiently stored in the flexible packaging body. Moreover, since the items to be packaged are stored in a flexible packaging such as a bag in a room with a good environment and the flexible packaging of the bag is closed, the items to be packaged inside the flexible packaging such as a bag will not be contaminated even if they are exposed to the outside. It was possible to provide a hygienic packaging method.

Furthermore, the packaging device of the present invention is such that the article to be packaged, together with a flexible packaging body such as a bag, can be transferred and stored in a packaging container from the drop opening on the lower surface of the frame held outside in a room with a good environment. Therefore, transfer can be performed efficiently.

In the second packaging method of the present invention, only the packaging body is brought into the environmentally friendly chamber, and the packaging container is not brought into the environmentally friendly chamber, so that bacteria and dust from the packaging container such as a cardboard box enters the environmentally friendly chamber. This provides a hygienic packaging method that does not cause contamination.
