[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to a device for packaging objects using a so-called half-folded film made of synthetic resin or the like, and more specifically to an apparatus for wrapping objects using a half-folded film that has improved transportability of the packaged objects. The present invention relates to a packaging device.

0002

BACKGROUND OF THE INVENTION Conventionally, in a device for packaging an object with a so-called half-fold film made of synthetic resin, etc.
As described in No. 64, in order to make the cross section of the half-folded film so-called U-shaped and to change the flow direction of the film to a direction perpendicular to that from the roll film mechanism, two upper and lower sections are generally used. An opening mechanism consisting of right-angled isosceles triangular members is used, and a belt conveyor mechanism for transporting the packaged items is disposed between the members, and each space provided between the belt conveyor mechanism and each of the members is A method has been adopted in which the object to be packaged is fed between the upper and lower pieces of a half-folded film folded back by an opening mechanism.

0003

[Problems to be Solved by the Invention] However, in the conventional packaging apparatus, a device having a guide plate for transferring the packaged items is attached to the transfer belt conveyor mechanism.
A support stand is installed in a direction perpendicular to the direction of transport of the object to be packaged, and the support stand and the support plate of the guide plate often come into contact with the half-folded film being transferred. It is desirable to solve these problems, such as preventing smooth and regular transfer of the film, and the fact that the support plate protrudes outside the transfer belt conveyor mechanism, making it difficult to carry out manual work around the transfer belt conveyor mechanism. It was rare.

[0004] Accordingly, an object of the present invention is to provide an apparatus for packaging an object using a half-folded film, which enables smooth and regular transport and packaging operations of the object and the half-folded film.

[0005]

[Means for Solving the Problems] The above objects of the present invention are achieved by the following means. That is, the packaging device for a packaged object using a half-folded film of the present invention includes a transfer belt conveyor mechanism for transferring the packaged object, and a roll group that feeds out the half-folded film substantially perpendicular to the transfer direction of the transfer belt conveyor mechanism. a roll film mechanism, which is located in front of the supply of the half-folded film and is provided above and below the transfer belt conveyor mechanism, and has a right-angled isosceles triangular film opening mechanism; and a sealing mechanism for sealing the object to be packaged. In the packaging apparatus for packaging items using a half-folded film, the transfer belt conveyor mechanism is configured to be movable in the width direction of the transfer belt conveyor mechanism, and the transfer belt conveyor mechanism is configured to be able to move freely in the width side of the transfer direction of the transfer belt conveyor mechanism. The present invention is characterized in that a guide member is provided on the frame of the main body on the front side in the transport direction of the object so as to protrude toward the transport front side of the transport belt conveyor mechanism.

[0006]

[Function] The present invention has the following functions due to the above structure. First, the half-folded film unrolled from the roll film mechanism is guided to the opening mechanism via appropriate guide rolls, and the roll film mechanism is guided for unwinding by right-angled isosceles triangular members provided above and below the transfer belt conveyor mechanism. Since the film is turned over by one side parallel to the roll and an oblique side continuous with the side, the cross section of the film has a U-shape. The half-folded film is pulled out in a direction perpendicular to the feeding direction, and the leading end of the half-folded film is once sealed by a sealing mechanism provided next to the transfer belt conveyor mechanism. Next, the transfer belt conveyor mechanism is activated, and the packaged items on the belt conveyor are placed into the U-shaped cross-sectional film. At this time, the object to be packaged is guided and transferred by a transfer guide plate of a transfer guide device having a support stand attached to the rear side in the direction of transfer of the object to be packaged. Since the transfer guide device is installed parallel to the direction in which the object to be packaged is transferred, the attachment of the device will not come into contact with the film and thereby prevent the transfer of the object to be packaged and the film. . Further, unlike conventional transfer guide devices, the support plate does not protrude significantly outside the packaging device, so if manual work around the packaging device is required, it is not obstructed.
