Description

Description: TECHNICAL FIELD The present invention relates to a packaging machine for four-fold and eight-fold packages.

(Prior Art) There are large bundles of articles, such as newspapers, in which a large number of four-fold parts are stacked, and small bundles, in which a small number of eight-fold parts are stacked. In many cases, the width of the packaging film used for packaging each of the packages is set to 1/2 for small bundles and for large bundles.

Therefore, when packaging a small bundle to be packaged by a packaging machine for a large bundle to be packaged, a packaging film that is too large is consumed for the small bundle to be packaged. It became remarkable and uneconomical.

Therefore, conventionally, in order to eliminate such waste of the packaging film, the four-fold wrapped object is a four-fold wrapping machine, and the eight-fold wrapped material is separately packaged by the eight-fold wrapping machine. .

(Problems to be Solved by the Present Invention) However, installing the four-fold wrapping machine and the eight-fold wrapping machine as described above is extremely effective in reducing the waste of the packaging film, but is relatively difficult to handle. The installation of an eight-fold wrapping machine to pack small quantities of eight-fold wrapped goods not only increases equipment costs, but also facilitates the planning of equipment arrangements in narrow delivery facilities with limited installation area. There was a problem that can not proceed.

In view of such a conventional situation, the present invention can easily perform the packaging of the four-fold package and the eight-fold package with a single packaging machine, and furthermore, does not waste the packaging film. It is an object of the present invention to provide a packaging machine for a four-fold package and an eight-fold package.

(Means for Solving the Problems) The packing machine for four-folded packages and eight-folded packages according to the present invention has a four-fold transfer port at both ends of a four-fold transfer path along a feeding direction of a conveyor. While the carry-out port is provided, an eight-fold transfer port is provided at one end of the eight-fold transfer path that joins the tri-fold with the four-fold transfer path, and is disposed near the four-fold transfer port. The four-fold film and the eight-fold film arranged near the eight-fold carry-in port have a vertical seal and a horizontal seal that can be processed by a sealer provided around the conveyor, respectively. .

(Function) The four-fold package is sent from the four-fold transport entrance to the four-fold transport path, and the vertical and horizontal seals are made on the conveyor located in the four-fold transport path. Is carried out of the aircraft.

On the other hand, the eight-fold package is fed into the eight-fold transport path from the eight-fold transport port, merges with the four-fold transport path, and is subjected to a vertical seal and a horizontal seal on the conveyor. Is carried out of the aircraft.
