<Prior Art> When packaging food or the like, the food is packaged in a flexible packaging body such as a bag made of synthetic resin, which is placed in a cardboard box for packaging. Here, when packaging food in a flexible package, it was conventionally performed under a normal environment, but in order to improve hygiene, this packaging is shielded from the outside such as a sterilization room and is better than the outside. It is desirable to do it in a good environment room that is kept in a good environment.

<Problems to be Solved by the Invention> However, since a packaging container such as a corrugated cardboard box contains a lot of germs and dust, if it is directly brought into a good environment room, the environment inside the room will be deteriorated.

Accordingly, the present invention provides a packaging method and an apparatus thereof that can carry out efficient packaging work while packaging a packaged item such as food under a favorable environment without bringing a packaging container into a good environment room. The purpose is to do.

<Means for Solving the Problems> Therefore, the present invention solves the above problems by providing the following packaging method.

The first packaging and packing method of the present invention uses a water resistant frame made of synthetic resin or wire as a transfer path in a good environment chamber which is shielded from the outside such as a sterilization chamber and kept in a better environment than the outside. It is carried along, and a flexible package such as a bag is attached to the frame inside or outside the good environment room, and the frame and the flexible package are sterilized to form a flexible package such as the bag in the good environment room. After storing the object to be packaged and closing the flexible package of the bag, carry out the frame together with the flexible package such as the bag from the good environment room along the transfer path outside the good environment room. It is characterized by taking out things.

The second packaging and packaging method of the present invention is the same as the first packaging and packaging method, except that the article to be packaged together with the flexible packaging body such as the bag body is taken out from the frame body outside the good environment room and then transferred to another packaging container. It is characterized by being replaced and stored.

Further, the present invention provides the following packaging and packaging apparatus suitable for the packaging and packaging method described above. This device is made of a synthetic resin or wire material having a water resistant frame, a flexible package such as a bag that is detachably mounted in the frame, and a sterilization chamber that is shielded from the outside and is better than the outside. A transfer path that allows the frame body to be transported to the outside again from the outside of the good environment room where the environment is maintained, and a flexible package such as a bag is attached to the frame outside or inside the good environment room. A mounting means, a disinfecting means for disinfecting the frame and the flexible package such as a bag inside or outside the good environment chamber, and a means for storing the article to be packaged in the flexible package such as the bag inside the good environment chamber. And a means for closing the mouth of a flexible package such as a bag containing the package, so that the package can be taken out together with the flexible package such as the bag from the frame outside the good environment room. It is what

In the above method and apparatus, after carrying out, the packaged object together with the flexible packaging body such as the bag body can be transferred from the frame body to the packaging container outside the good environment room, or can be stored in the packaging container. Alternatively, the flexible package may be put in the distribution process as it is without being transferred.

As the transfer path, in addition to a belt conveyor or a roller conveyor, a transfer table that moves on a rail or the like that can transfer the frame through a fixed path can be appropriately selected and adopted.

As the frame body, the lower surface is used as a drop port, and the packaged product can be taken out together with the flexible package body such as the bag body from the lower port of the frame body, and only the upper surface is opened. The flexible package such as a bag can be taken out together with the flexible package, the side surface is opened, or the side wall of the frame is collapsed to be in an expanded state. As long as it can be taken out, an appropriate structure can be adopted.

<Operation> In the packaging method and apparatus of the present invention, the frame body and the flexible packaging body are merely brought into the good environment chamber, and the packaging container is not brought into the environment. Further, the flexible packages such as the frame and the bag brought into the good environment room are sterilized outside or inside the good environment room. As a result, bacteria and dust in the packaging containers such as cardboard boxes will not contaminate the good environment room, and
By performing the disinfection, it is possible to prevent the bacteria and dust of the flexible packaging body such as the frame body and the bag body from contaminating the inside of the good environment room. A flexible package such as a bag is attached to the frame inside or outside the good environment chamber, and the article to be packaged is stored in the flexible package such as the bag in the good environment chamber. The items to be packaged can be stored efficiently. Next, since the object to be packaged is stored in a flexible package such as a bag in a good environment room and the flexible package of the bag is closed, the object to be packaged inside the flexible package such as the bag does not come out to the outside. Not polluted.

Here, the following configuration is given as an example.

As shown in FIG. 27 (I), two long strip-shaped plate-like bodies (304) (304) are arranged in parallel so that the plate surfaces face each other. The plate-like bodies (304) (304) are provided with hydraulic actuators (306) (306) on the outer sides thereof so that they can slide in directions away from each other, and the hydraulic actuators (306) (306) It is fixed to the tip. Guide bars (305) (305) parallel to the sliding direction are provided on both sides of the hydraulic actuators (306) (306) in the sliding direction to guide the actuators (306) (306) to slide. One plate-shaped body (304) is provided with one open / close conveyor (302) on the surface facing the other plate-shaped body (304), and similarly, the other plate-shaped body has the other open / close conveyor ( 30
3) is provided.

Pressing plates (309) (309) (309a) that arrange the frame body (41) on both open / close conveyors (302) (303) and hold it.
To provide. The pressing plates (309) (309) on both sides slide on the open / close conveyors (302) (303) to press and hold both side surfaces in the traveling direction of the frame (41). The front pressing plate (309a) presses and positions the frame body (43) from the front (with respect to the traveling direction). By these positioning and holding means, the article to be packaged in the bag (43) is surely dropped below the open / close conveyor. Pressing plate (309) (309) (30
9a) is designed to slide to the original position if the packaged item falls. In particular, the front pressing plate (309a) is designed to be able to escape upward so as not to hinder the subsequent movement of the frame.

The open / close conveyors (302) (303) may be belt conveyors, but in this embodiment, they are roller conveyors. This roller conveyor has a plurality of rollers (r) rotatably fixed to the plate-like bodies (304) (304). The rollers (r) are arranged so that their axial directions are parallel to each other, and form a horizontal roller group along the transfer direction. It suffices that an appropriate one of the plurality of rollers (r) rotates by itself to supply the transfer force (of course, it is not possible to prevent all the rollers (r) from rotating by themselves). Absent). The rollers (r) are arranged with an appropriate distance (d) from each other. By using the roller conveyor in this way, it is possible to set a hanging part (f) described later.

As shown in Fig. 27 (II), the pressure plates on both sides (309)
At an appropriate position of (309), such a hanging part (f)
(F) is provided.

The frame body (41) is a closed open / close conveyor (302) (303).
It is transferred to the top and stopped at a predetermined position, and the pressing plate (30
9) Positioned and held by (309) and (309a). When the open / close conveyors (302) (303) are opened in this state, the packaged object already packaged in the bag (43) opens the bottom lid (42) of the frame body (43) in a double door shape by its own weight, It falls down naturally.
Then, it is stored in the cardboard box (22) on the lower transfer conveyor (21) by spontaneous fall.

(Modification Example of Lower Feeding Conveyor) As shown in FIG. 28, the lower feeding conveyor includes an intermittent feeding chain (401) (401) stretched in parallel with each other, and a support rail ( 402) ... and. Two sets of the support rails (402) are set, and a plurality of sets are arranged at equal intervals.

The cardboard box (22) has a pair of support rails (402) (402).
Placed on top. Specifically, the lower side flap (22b) of the lower portion of the corrugated board (22) is placed on the support rails (402) (402) in a bent state, and the long side flap (22c) is placed.
Respectively hang outside the support rails (402).

The support rails (402) of each set are stopped at the mounting position (a), the loading position (b) and the feeding position (a) by intermittent feeding of the chain. And this lower conveyor is the 7th
It is arranged below the conveyor (17) so as to be orthogonal to this feeding direction, and the loading position (b) is arranged directly below the seventh conveyor (17).

A support (403) is arranged below the loading position (b). This support body (403) is provided between the intermittent feed chains (401) (401) and between the pair of support rails (402) (402) by an appropriate lifting means such as a fluid pressure cylinder or screw feeding means.
Short side flap (22b) that is bent further between
It goes up between (22b) and rises above the cardboard box (22). As a result, the open / close conveyors (302) (303) of the seventh conveyor (17) are opened to spontaneously drop the bag (4
3) Receive the items to be packaged. Then, the support (403) is gradually lowered by the elevating means, and the article to be packaged is placed on the folded short side flaps (22b) (22b) without impact. Further, only the support (403) descends and escapes below the lower conveyer, whereby the operation at the loading position (b) ends.

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 described.

On the right side of the mounting position (a) in the figure, a pair of fixed rails (41
0) (410) are arranged. Fixed rail (410) (410)
Is fixed to the support rails (402) (402) at the same interval and the same height, and the left end thereof coincides with the support rails (402) (402) stopped at the mounting position (a).

The cardboard box (22) is set to the left end of the support rails (402) (402) by a take-out means such as a suction pad (411), and the folding guide plates (412) (412) are used to flap the short side flaps. (22b) and (22b) are bent. Then, by a feeding means (not shown) such as a fluid cylinder,
Between the support rails (402) (402) sent from right to left on the fixed rails (410) (410) and stopped at the mounting position (a)
Transferred to the top.

On the other hand, at the delivery position (c), fixed rails (420) (420) for delivery are arranged on the right side in the figure. The left ends of the fixed rails (420) (420) for carrying out coincide with the support rails (402) (402) stopped at the sending position (c),
The distance between the rails is getting narrower as you move to the right. The bending guide plate (421) (4
21) is arranged. The corrugated cardboard box (22) in which the items to be packaged have already been loaded into the fixed rails (420) (420) for carrying out from the support rails (402) (402) by the sending device such as the fluid pressure cylinder (422) on the right side in the figure The long side flap (22c) by the folding guide plates (421) (421)
(22c) is folded. A belt conveyor (423) is arranged on the right side, and in the corrugated cardboard box (22), the flaps on the upper part are folded in here, and gum tape is applied to the upper and lower surfaces by the applying device (430), and the packing is completed. . Various known devices can be used for folding the flap and applying the gum tape, or it can be performed manually.

(Other Embodiment of Frame) Next, another embodiment of the frame will be described with reference to FIG.

The frame body (41) has a bottom lid that opens like a double door, but the frame body (501) of this embodiment has a bottom lid (502) (50).

Has a tip protruding outward in the closed state, and an engaging portion (503) bent upward is provided at the tip. Also, from the left and right side parts of the frame body (501), the arm part (504)
(504) is projected.

A seventh conveyor (17) for transferring the frame body (501)
Is changed to That is, instead of the open / close conveyor, the arms (504) are arranged on both sides of the frame (501) from below.
The transfer means can be changed to a guide rail (505) (505) that supports (504) and a fluid pressure cylinder (not shown) that is moved by pushing (or pulling) the supported frame body (501). . Further, the object to be packaged in the frame is dropped by pulling out the bottom lids (502) (502). This withdrawal may be performed by providing an engaging portion (507) at the rod tip of the fluid cylinder (506) and engaging the engaging portion (507) with the engaging portion (503) of the bottom lid. This frame (501)
Attach the support (403) for controlling the falling speed to the bottom lid (503).
This is advantageous in that it can be lifted up to just below, and the shock of falling can be reduced.

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

In the embodiment, the articles to be packaged in one bag are put in one package, but two or more packaged articles may be put in one package.

When the object to be packaged is a solid or a highly viscous fluid, it is desirable that the cross-sectional shape of the frame body be substantially equal to or smaller than the cross-sectional shape of the package body such as a corrugated cardboard box. As a result, the objects to be packaged can be transferred smoothly. When the fluidity of the object to be packaged is large, even if the frame is larger, it can be transferred to the package due to its fluidity.

The frame body can be changed to a box-shaped frame, 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 is opened and the object to be packaged is dropped, but the object to be packaged may be taken out from the side part or the upper part.

The package may be a cardboard box or another container such as a box or a can made of another material.

The transfer path may be a straight line other than the U-shaped one as in the embodiment, and may be carried in and out of the good environment chamber by reciprocating on the same transfer path. .

<Effects of the Invention> In the present invention, the frame body and the flexible packaging body are merely brought into the good environment room, and the packaging container is not brought into the environment. Further, the flexible packages such as the frame and the bag brought into the good environment room are sterilized outside or inside the good environment room. As a result, bacteria and dust in packaging containers such as cardboard boxes will not contaminate the good environment room, and by disinfection, bacteria and dust in flexible packaging such as frames and bags will be good environment room. Can be prevented from polluting. A flexible package such as a bag is attached to the frame inside or outside the good environment chamber, and the article to be packaged is stored in the flexible package such as the bag in the good environment chamber. The items to be packaged can be stored efficiently. And since the object to be packaged is stored in a flexible package such as a bag in a good environment room and the flexible package of the bag is closed, the object to be packaged inside the flexible package such as the bag is not contaminated even if it goes out. .

Therefore, the present invention can provide a method capable of hygienic and efficient packaging.

Furthermore, after taking out the object to be packaged together with the flexible package such as the bag from the frame outside the good environment room, the object to be packaged is transferred and stored in another packaging container to maintain the object to be hygienic. As it is, it can be packed in a packing container such as a cardboard box.

Further, the present invention can provide a device capable of performing hygienic and efficient packaging suitable for carrying out the above method.
