2. Description of the Related Art Two long plastic films are supplied from opposite directions, an encapsulating material is filled between the films, and the periphery of the films is heat-sealed to form a film in a bag shape. The packaging device according to the above has already been proposed.
(Japanese Patent Application No. 2-106133) In this packaging device, the films supplied in a substantially horizontal state from opposite sides of the device are welded and joined in the central part of the device, and the article to be packaged is joined on the joined part of the film. After mounting, both films are fed out toward the central part and the film sandwiching the object to be packaged by the weight of the object to be hung is hung in the space formed in the central part of the device, and the object to be packaged from the outside of the film. A bag-shaped package is formed by heat-sealing a portion corresponding to the periphery.

On the upper end side of the space portion, inclined film guide plates for guiding the film to the space portion are arranged in parallel so as to face each other. It is set large enough to pass through. The object to be packaged is placed on the film arranged along the upper surface of the film guide plate, and depending on the unwinding of the film, the space is hung along with the film from the gap between the two film guides. Moved to the department.

[Problems to be Solved by the Invention] Vegetables, especially leafy vegetables such as spinach and chrysanthemum, have considerably different volumes at the root part and the leaf part. Therefore, as shown in FIG. , The roots have a gathered shape when placed on the film, and the vegetables at the top are arranged in an inclined state with the roots facing downward. When the film is fed out in this state, the leaf portion is squeezed by the guide plate and gradually moves into the space, but the root portion suddenly moves into the space and gathers at the bottom of the film, as shown in FIG. As shown, the roots of the vegetables are concentrated in one corner of the bag, and the vegetables are not arranged side by side in the bag, and the vegetables at the top of the bag are arranged in a state in which the vegetables are inverted by nearly 90 degrees. As a result, there is a problem that the packaging form is deteriorated and the commercial value is impaired.

The present invention provides a vegetable feeding guide device capable of visually wrapping leaf vegetables as described above inside a rectangular bag-shaped package, in particular, by arranging the root portions having a small volume evenly. This is an issue.

[0006]

[Means for Solving the Problems] A packaging space portion is opened upward, and a packaging film is arranged so as to be continuously supplied into the packaging space from opposite sides of the opening portion. The packaged object placed on the joint portion of the film is hung down in the packaging space by feeding out both films and at the same time the packaged object is wrapped between both films and arranged opposite to each other in the space. The straightening member corrects the form of the packaged object through the film, and at the same time, the heater disposed around the straightening member fuses both films around the packaged object to package the packaged object. In the packaging device described above, a positioning piece for restricting one end side position of the packaged object is installed in the opening, and the packaged object is arranged from both side edges of the positioning piece. It is intended to solve the above problems by forming a pair of chute guide piece which is formed opposite gradually such that the interval becomes narrower downward from BiKatsu above.

[0007]

Since the feeding guide piece for restricting the free fall of the root portion of leaf vegetables is formed in the portion to be packed of the packaging device, the root portion of leaf vegetables is sequentially dropped into the packaging space portion according to the hanging of the film. Therefore , the roots of leafy vegetables can be evenly arranged in the rectangular package without the roots being concentrated in one corner of the bag.

The leading ends of both films F are fused and integrated with each other at the central portion of the opening 3 via the upper surface of the film 4.
Both drive rollers 6 and 6 of the film feeding mechanism are rotationally driven in synchronism with each other in opposite directions, whereby the fusion-bonded portion F ′ of both films F droops into the packaging space 2.

In the space 2, a pair of heater devices 8, 8 are provided in a position opposed to each other with the film F hanging in the packaging space 2 sandwiched therebetween, in a normally separated state. . The heater devices 8 and 8 are driven by a drive mechanism (not shown) between the separated positions facing each other in the space and the positions at which the heater devices 8 and 8 approach each other at the central position in the space.
Each of the heater devices 8 and 8 has a horizontal heater 9 horizontally arranged above the article V hung in the packaging space 2, and a film F from below the horizontal heater 9. A vertical heater 10 is arranged vertically along one side. The horizontal heater 9 laterally fuses the upper part of the portion containing the article V to be packaged and, at the same time, melts and cuts the continuous film F hanging in the space 2 from the portion to the end portion of the film F. The new fused end F'is formed.

At the inner portion defined by the horizontal heater 9 and the vertical heater 10, a packaged object V hanging in the space 2 is formed.
A correction member 11 formed of an elastic member such as a sponge for suppressing the swelling of the film F sandwiching the film and correcting the packaging form is arranged. The correction member 11 is formed in a shape in which the central portion is recessed.

A discharge opening 12 for discharging a package is formed in a portion of the packaging device 1 which is below the space portion 2. The package P melt-fused by the horizontal heater 9 is the heater device 8. , 8 fall to the separated position, and are dropped from this opening and taken out of the packaging device 1 by a chute or the like not shown.

Between the two film guide plate members 4 and 4 installed on the opposite sides of the upper opening 3 of the space 2, a mounting position of the root V'of vegetables to be packaged V is set. A positioning piece 13 for regulating is provided. The positioning piece 13 is screwed to the bracket 15 fixed to the frame portion 14 of the packaging device 1 and is arranged between the film guide plates 4 and 4, and the mounting hole 17 into which the screw shaft 16 is inserted is inserted. Is formed as a long hole, the arrangement position is variably adjustable according to the size of the article V to be packaged and the width dimension of the film F. This positioning piece 13
Is set slightly closer to the center than the arrangement position of the vertical heater 10.

Inserting guide pieces 18, 18 are formed so as to project from the both side edges of the positioning piece 13 by a predetermined length in the direction in which the article V to be packaged is arranged. Both feeding guide pieces 18, 18 are opposed to each other so that the facing gap is large on the upper end side and narrows on the lower side, and both feeding guide pieces 1 at the lower end position.
The distance between the guide pieces 8 and 18 is set to be narrower than the distance between the guide pieces 4 and 4, and the projecting length of the input guide piece 18 is such that the root portion V ′ of the vegetable to be packaged is the guide piece 1
It is set according to the type of the article V to be packaged so as to be accommodated between 8 and 18. Further, the inclined guide surfaces 19 and 19 of the feeding guide piece 18 which face each other are made of a material having a good slip such that a root portion V ′ of a vegetable to be packaged easily falls into the packaging space 2, for example, a metal plate. Teflon coated surface or plastic material such as polycarbon is used.

Next, the operating state of the packaging device 1 will be described. In the normal state, the wrapping film F is pulled out from the film winding body 5 to drive the driving roller 6 and the pressing roller 7.
The fusion-bonding portion F ′ is arranged in the central portion of the upper opening portion 3 of the packaging space portion 2 in a state in which the ends of both packaging films F are fusion-bonded via the space between them and the upper surface of the film guide plate 4. There is. As for the leafy vegetables V that are to be packaged, the predetermined amount of the packaging unit is the root portion V '.
Is struck on the positioning piece 13 and placed on the packaging film F. At this time, the leaf tips having a large volume are arranged along the upper surface of the film guide plate 4 in a bulky manner, while the root portions V ′ are arranged inside the feeding guide piece 18 in an integrated manner.

When a start switch (not shown) is turned on in this state, the drive rollers 6 and 6 are rotationally driven in the direction of the arrow shown in FIG. 4 (b), and both packaging films F are fed toward the opening 3. Be done. The fusion bonding part F ′ of the packaging film F is hung down inward of the space part 2 together with the vegetables due to the weight of the vegetables, and at this time, the root parts V ′ of the vegetables are the feeding guide pieces 18, 18.
As a result, all of them are prevented from being collected all at once and fall in parallel with the hanging of the leaf tip portion, and they are sequentially dropped from between the feeding guide pieces 18 and 18 and are sandwiched between both packaging films F to be drooped into the space. .

The drive of the drive roller 6 is stopped after the packaging film F has been fed out for a predetermined length determined according to the amount of vegetables to be packaged, and then the pair of heaters in the space 2 is heated. The devices 8, 8 are driven in the proximity direction. The heater devices 8 and 8 are driven by driving the pair of heater devices 8 and 8.
From the outside of the packaging film F in which the correction members 11, 11 arranged in
Are pressed to suppress unnecessary bulging of the packaging film F and correct the packaging form. In this case, since the straightening member 11 is made of an elastic material, it is possible to prevent the vegetables from being damaged by pressing the vegetables more than necessary.

When the correction of the package P is completed, the corresponding lateral heaters 9 and 9 of the two heater devices 8 and 8 are horizontally arranged above the vegetables V in which the packaging film F is housed. The vertical heaters 10 and 10 vertically press the films from the position of the horizontal heater 9 along one side of the film F in the lower portion and simultaneously heat the films to fuse the films in the portions. At this time, the lateral heater 9 fuses the film and at the same time melts the film to form a new fused end F ′ at the end of the packaging film F. After that, the pair of heater devices 8 and 8 are driven in a direction in which they are separated from each other, and the package P that has been packaged is taken out of the packaging device 1 through the discharge opening 12.

It should be noted that the facing interval between the feeding guide pieces 18, 18 needs to be selectively set according to the form of the article to be packaged and the like. In this case, if it is possible to replace the positioning piece 13 together with the positioning piece 13, it is convenient because one packaging device 1 can be used for the packaging work of various kinds of packaged objects.
