DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging apparatus for enclosing a package in a film, continuously and automatically packaging the film, and sequentially transporting and carrying out a film packaging bag containing the package.

[0002]

2. Description of the Related Art As a packaging apparatus of this type, a film supply apparatus for pulling out and guiding a long film with its upper edge side opened as an open portion while being folded in a half-fold state, and a cut-off edge of the film. A film drawing chuck device that repeats a reciprocating operation of chucking and drawing the drawing end, chucking the drawing end, pulling back, moving back again after the drawing and sequentially cutting and cutting, and chucking and drawing the drawing end, which is a cutting edge to be cut; A vertical sealing device for heat-sealing the film transferred between the drawer chuck device and the film into two strips with a small clearance in the vertical direction, and a package storage for storing the package in the bag-shaped film by the vertical seal. Device, a film cutting device for cutting a predetermined position of the film, and cutting by the film cutting device A packaging device comprising: a horizontal sealing device for thermally sealing the upper end opening of the film packaging bag in the horizontal direction; and a separating and cutting device for separating the film packaging bag packed by the horizontal sealing device and containing the package. ing.

In this case, the leading end of a film of a predetermined width folded in a V-shape having an opening at the upper end side is chucked and pulled out by a drawer chuck device, and the film is drawn out and supplied from a film supply section. On the film thus obtained, two vertical seals are applied one after another at intervals of one bag by a vertical seal device at a small interval, and the space between the two vertical seals is cut in advance by a film cutting device while leaving a little upper end of the film. The upper opening of the film packaging bag formed between the vertical seals by the vertical seal is opened by the package storage device, the package is put in, and the upper opening of the film packaging bag in which the storage of the package has been completed is opened by the horizontal sealing device. Laterally seal and seal, cut off the uncut portion left in advance and cut with a cutting device. And the chuck is moved back a beam drawer chucking device, it is pulled out movement, are sequentially package containing film packaging bag repeating this operation so as to sequentially transport emissions.

[0004]

In such a packaging device, the film pulling chuck device chucks the leading edge of the film and pulls out the film, and the front portion of the drawn film stores the package as described above. It is a film packaging bag with a package.

Therefore, in the case where the film is large and contains a large amount of packages and the weight is increased, the structure in which the film is simply pulled out by the film pull-out chuck device does not allow the film to be transported smoothly, and the packages in the film cannot be transferred. There is a problem that the amount must be limited to a small amount.

Further, if a conveying device for supporting the film is provided below the package storage device and the conveying device is simply constituted by an endless belt, the lower edge of the film is conveyed when the film is conveyed. When the package is put in this state, the package will not enter the bent lower end portion, and the storage space for the film packaging bag will be reduced by the amount of the bend. When an object is loaded, a pulling force (downward pulling force) acts on the film, so that the upper edge of the film held by a packaging storage device or the like falls off or the film is not transported smoothly. Also, when the lower end of the film is bent in this manner, the film is distorted by the vertical sealing device or the film cutting device located immediately before the film transfer side, and the heat sealing by the vertical sealing device or the vertical cutting by the film cutting device is appropriately performed. In some cases, a failure that cannot be achieved well may occur.

[0007] The present invention solves such a problem, and even if the film is large and accommodates a large amount of packages and is heavy, stable and smooth packaging movement is possible. It is an object of the present invention to provide an excellent packaging device capable of realizing reliable and quick automatic packaging.
