In this manner, a disassembly at the time of transportation is made unnecessary and dimensions can be adjusted appropriately.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a packaging device for wrapping a plurality of packages by wrapping a plastic film around the packages while stretching the plastic film.

[Conventional technology]

Case packaging or boxing is a common method for transporting large quantities of single products. Large quantities of single products are typically stacked in cardboard boxes or wrapped in kraft paper with the edges of the kraft paper glued or taped. Another method of transporting such products is to form a monolithic package by wrapping a stretchable film around the product in a stretched state and shrinking the film, which can be done, for example, by This is a "packaging method and apparatus" disclosed in Japanese Patent Publication No. 59-52087. In other words, multiple pieces of luggage are stacked on the top surface of a support stand that is driven and rotated by a motor or the like.
A stretchable plastic film wound into a roll is attached to a film supply device adjacent to the support base, the starting end of the stretchable plastic film is fixed to a load on the support base, and the support base is rotated. The stretchable plastic film is fed out at a speed lower than the rotational speed of the stretchable plastic film, and is wound around the stack of luggage while being stretched.

[Problem to be solved by the invention]

However, in the prior art apparatus, the packaging apparatus itself is large in size, so there is a transportation problem in that the packaging apparatus must be disassembled, transported, and assembled at the installation site of the apparatus.

In addition, since the dimensions of the packaging device (for example, the distance between the film supply section and the package to be packaged, the height at which the film supply section can supply the film to the package, etc.) are fixed, the size of the package to be packaged may vary. It is difficult to properly adjust the device accordingly. That is, for example, if the dimensions of the packaging device (and therefore the distance between the film supply unit and the load to be wrapped) are too large compared to the load to be wrapped, there is a risk that the film will neck down; If the packaging device is too small compared to the cargo to be packaged, there are problems in use, such as the inability to use the device.

SUMMARY OF THE INVENTION An object of the present invention is to provide a packaging device that does not require disassembly during transportation and whose dimensions can be appropriately adjusted depending on the size of the cargo to be packaged.

[Means to solve the problem]

In order to achieve this objective, the present invention provides a fixed base having a hollow support member, a table rotatably attached to the fixed base and for placing a load to be packaged, and a table that includes a fixed base having a hollow supporting member; a support base having means for rotating, a connecting member inserted telescopically into the hollow support member; a mast device provided on the support base; a film supply unit; A packaging device is provided that includes a carriage for placing the carriage and a device for raising and lowering the carriage vertically along the mast device.

In the packaging device according to the present invention, preferably, the mast device includes an outer mast fixed to the support base and an inner mast provided inside the outer mast, and the lifting device carries the film supply section. This is a packaging device that moves a placed carriage and an inner mast vertically at a constant speed ratio.
