Abstract

PURPOSE:To permit easy cutting and removing of bands, by pressing in one direction a compressible articles packed with the bands bound around the peripheral surfaces thereof, whereby the bands are cut off from one face thereof and the cut pieces of the bends are removed from the opposite face thereof. CONSTITUTION:The packed articles 2 such as corrugated fiberboards and kraft pulp bound together with bands 1 into a square form are securely placed on a floor F and, from above it, a push rod 3 of a compressor is moved downwardly into contact with the upper face of the packed articles 2 and a vertical compressive pressure is then applied thereto, resulting in the occurrence of the looseness of the front and back faces 2a and 2c of the packed articles 2 and the formation of a gap between the bands 1 and the packed articles 2. In this condition, a cutter 4 is inserted into this gap and pulled outwardly to cut bands 1. Before cutting the bands 1, a rod-shaped band remover 5 is inserted between the back face of the packed article and the bands and, after cutting them off, the packed articles are turned outwardly or moved straight and the cut pieces of the band 1 are then removed from the packed articles 2. Therefore, this method permits easy automatic cutting and removing of the band and safe unpacking including the after-treatment of the removed bands.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for unpacking a banded package, particularly a package that is elastically deformable by compression.

[Conventional technology]

Banding as a packaging method is widely used in various fields. For example, cardboard, waste newspapers, kraft pulp, rags, etc. are tied together using bands made of wire, string, rope, etc., and then transported to the destination. However, until now, there was no mechanical method for unpacking the band, and workers had to use tools such as nippers to cut the band and remove it from the package.

[Problem to be solved by the invention]

Generally, an unpacking work site is often an operating area of a forklift or the like, and it is dangerous work for a worker to manually remove the band, especially the wire, from the package under such an environment. Furthermore, the wire removed from the package must be stretched against the stretching force;
The procedure is extremely troublesome. If this procedure is incorrect, the removed band will be dragged along with the unpacked material transport line, causing machine trouble and personal injury.

The present invention solves the above-mentioned problems, and focuses on the fact that these packaging bodies, including the aforementioned cardboard boxes, waste newspapers, kraft pulp, waste cloth, etc., can be compressed and deformed, and utilizes this property to create packaging bodies. It is an object of the present invention to provide a method for easily removing a band from a container and processing the removed band.

[Means to solve the problem]

In order to achieve the above object, in the method for unpacking a band package of the present invention, a compressible package whose peripheral surface is bound with a band is compressed in one direction, and two opposing sides of the compressed package are The band on the first surface side of the compressed package is cut using the gap formed between the band and the binding band as an insertion space for a band cutting and cutting band removal device, and the band is cut from the second surface side. The purpose of this is to remove the

[Effect]

There are two types of compressible packaging: the material of the packaging can be compressed, and the space between the eyebrows can be compressed.

A typical example of a material that can be compressed and deformed is foam rubber.A laminate that can be compressed between zero layers means that even though the material itself has almost no compressibility, it can compress the space between the eyebrows. It is a laminate whose volume is reduced by . This includes cardboard, waste newspapers, kraft pulp, rags, and most packaging that is typically tied together using wire, string, or rope. This type of compressible package is compressed to a certain extent and tied together with a band, but in the present invention, the package is further compressed in one direction, and a band loop is formed to keep the package in a certain shape. A gap is created between the compressed packaging and the band is cut by inserting a cutter into one gap, and a band removal tool is inserted into the other gap to remove the cut band. This is what we do. Due to the compression of the package, at least a portion of the band passed around its circumference is supported by the surface of the pressing pad of the compressor, so that there is no recoil or impact when cutting the band, and the cut wire is removed from the package. When the body is compressed or decompressed, it can be easily removed.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1(a) shows a package 2 in which a laminate of cardboard, kraft valves, etc., for example, is packed with a band 1 and kept in a rectangular shape. Note that the band 1 is attached to the front 2 of the package 2.
A, the hook is laid in two strips across the bottom surface 2b, the back surface 2C, and the top surface 2d.

In FIG. 1(b), the package 2 is placed on the floor F, and the press pad 3 of the compressor is pressed down from above to press against the upper surface of the package #2, compressing it in the vertical direction. Packing body 2
receives compressive force and reduces its volume, but the loops of the band 1 are maintained at a size that retains the original shape of the package 2, and the portions of the band 1 along the top surface 2d and bottom surface 2b of the package 2 are Since it is supported by the pressing pad 3 and the floor F, in the case of the embodiment, the front surface 2a and the back surface 2C of the package 2 are loosened, and a gap is formed between the facing surfaces of the band 1 and the package 2. In that state, first insert the cutter 4 into the gap on the front side,
The band 1 is cut by pulling the cutter 4 outward as shown in FIG. 1(C).

On the other hand, as shown in FIG. 1(d), a rod-shaped band removal tool 5 is inserted into the gap on the back side before cutting the band 1.
After cutting the band 1, it is rotated or linearly moved outward and the cut band 1 is removed from the package 2. The band may be removed either before or after the pressing pad 3 is moved upward. FIG. 1(e) shows an example in which a forked arm rod 6 is used as the band removal tool. Band 1 on the fork of armrest 6
After cutting the band, the arm rod 6 is rotated about its axis and the band 1 is wound around it, so that the cut band 1 is wound around it in a coil shape. This is suitable when wire is used for band 1. The forked arm rod 6 allows unpacking of the package including post-processing of the band.

In the case of a package in which bands are cross-hung, cut the band and remove the cut band by inserting a cutter or removal tool into each gap between the band and the package, which are formed on both sides as well as on the opposite sides of the front and back. conduct.

Note that the direction of compression of the package is not limited to the vertical direction; if the package is compressed while supporting at least the two opposing sides covered with bands, a gap will be formed between the remaining two sides of the pond and the band. . The package can be opened vertically or horizontally. The same applies even if the cross section of the package is circular or irregular.

〔Effect of the invention〕

As described above, according to the present invention, the characteristics of the package are utilized, and by simply compressing and deforming the package, the band that binds the package can be separated from the outer surface of the package, and the band can be easily cut and removed mechanically. Furthermore, by winding up the band to be removed onto the removing tool, it is possible to safely unpack the band, including post-processing of the removed band.

According to the present invention, it is possible to ensure the safety of the work environment for unpacking the packages delivered to the work site, and to mechanically and efficiently perform the unpacking work of the packages, including the processing of the cable ties.
