DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for wrapping spherical vegetables such as cabbage or lettuce or spherical fruits such as pomelo in a film. .

[0002]

2. Description of the Related Art Conventionally, in this type of packaging apparatus, a film wound on a film roll is clamped at a leading end thereof by a drawer mechanism, and is spread on an upper surface of a table plate having an insertion port by moving the drawer mechanism. And pull it out
After the film is cut by the cutting mechanism, the spherical object to be packaged is dropped downward from the upper surface of the film piece into the input port, so that the spherical object is wrapped by the film piece. The edge of the film piece,
The pair of shutters disposed in the main body case are narrowed down by approaching inward, and the narrowed portions are then bound by heat fusion or the like.

[0003] By the way, when packaging spherical vegetables and the like,
Use a long film printed with brand marks indicating the place of origin or producer etc. at a constant pitch along the longitudinal direction, and apply this long film to a piece of film in the middle part of each brand mark. The film piece with the brand mark is used to wrap the spherical object such as a spherical vegetable around the brand mark on the film piece, in other words, wrap it in a state where the brand mark is clearly visible. That is being done.

The pitch interval of each brand mark in the long film with the brand mark is set arbitrarily according to the size of the spherical object to be packaged. In other words, the pitch with the brand mark is long. In the lengthy films, there are those in which the pitch interval of the brand mark is widened and those in which the pitch is narrowed.

[0005]

On the other hand, in a conventional packaging apparatus, as described above, a long film wound on a film roll is moved by a drawer mechanism to a table plate having an input port. After being pulled out so as to be spread on the upper surface, the film is cut into pieces by a cutting mechanism, and a spherical object to be packaged is put into the above-mentioned inlet from the upper surface of the film piece, and is packaged. By this, as described above, when using a long film printed with a brand mark indicating the place of origin or producer, the film piece cut from this long film, It is quite difficult to make the brand mark on the film piece substantially coincide with the input port on the table plate on the upper surface of the table plate. If the pitch of the brand mark is changed to a different one according to the size of the spherical object, the brand mark will be greatly displaced from the input port. There has been a problem that landmarks on a film piece are shifted to the narrowed-down portion of the film piece and cannot be seen, which often occurs.

According to the present invention, when a spherical object is wrapped and packaged with a film piece cut from a long film with a brand mark, the spherical mark can be packaged so that the brand mark can be surely seen. It is an object of the present invention to provide a packaging device which has been described above.

[0007]

SUMMARY OF THE INVENTION In order to achieve this technical object, the present invention provides a table plate having an inlet for a spherical object, a mounting table for a film roll provided at one end of the table plate, and a cutting mechanism. And a reciprocating film pull-out mechanism that moves forward along the upper surface of the table plate toward the cutting mechanism and then retreats. A clamping means for clamping and releasing the clamp at the retracted position, and a film squeezing mechanism disposed below the table plate, wherein the cutting mechanism is provided with the film drawing mechanism. While a cutting position adjusting means for adjusting the movement along the direction of the reciprocating motion is provided, the cutting position adjusting means extends between the film unwinding mechanism side and the cutting mechanism side. A forward position regulating means for regulating the end point of the forward movement toward the cutting mechanism on the film unwinding mechanism side, and further, a retreat position for regulating the end point of the backward movement of the film unwinding mechanism over the film unwinding mechanism and the table plate side. The restricting means is provided so that the end point of the retraction by the retreat position restricting means can be adjusted to move along the reciprocating direction of the film unwinding mechanism. "

[0008]

In this construction, the film draw-out mechanism reciprocates between the forward position regulating means provided over the cutting mechanism and the cutting mechanism, and the retreat position regulating means provided over the cutting mechanism and the table plate. At the end point of the forward movement, the leading end of the film unwound from the film roll is clamped by the clamp means, and the film is retracted in this state, whereby the film is pulled out to the upper surface of the table plate and the clamp is released. On the other hand, since the cutting mechanism cuts this film piece into film pieces, in this state, a spherical object to be packaged is thrown into the slot in the table board from the upper surface side of this film piece, thereby Since the periphery of the film piece is squeezed by the squeezing mechanism, the spherical object can be wrapped and packaged.

In this case, the cutting mechanism is configured to adjust the movement along the direction of reciprocation of the film pull-out mechanism by the cutting position adjusting means, while being controlled by the retreat position restricting means with respect to the film pull-out mechanism. The end point of the retraction is also configured to be adjustable in the direction of the reciprocation of the film unwinding mechanism, so that the distance from the input port on the table plate to the cutting mechanism, and the retraction of the film unwinding mechanism While the distance to the end point is set to half the dimension of the pitch interval according to the pitch interval of each brand mark in the long film, first, the brand mark on the film is made to coincide with the input port. By setting, a film piece is placed on the upper surface of the table board, It is possible to supply under approximately identical to the state at the center of the inlet of the marks in the table plate.

Therefore, according to the present invention, when a spherical object is wrapped and packaged with a film piece cut from a long film with a brand mark, even if the pitch interval of the brand mark changes, the brand mark is not changed. It has the effect that it can be always wrapped and wrapped in a visible state.
