Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for unpacking a banded package and a winding rod for the band used for packing.

[Conventional technology]

Banding as a packaging method is widely used in various fields. For example, industrial cardboard materials such as waste cardboard and craft paper are tied together using bands made of wire, string, rope, etc. to keep them in a certain shape. However, until now there was no mechanical way to unpack the bands, so workers had to cut the bands using nippers.
This was disposed of by removing it from the package.

[Problem that the invention seeks to solve]

Generally, unpacking work sites are often areas where forklifts operate, and it is dangerous work for workers to manually remove bands, especially wires, from packages in such an environment. Furthermore, the wire removed from the package must be bent against the stretching force, which is extremely troublesome. If this procedure is done incorrectly, the removed band will be dragged along with the unpacked material transport line, and
The object of the present invention is to solve the above-mentioned problems and provide a method for easily removing the band from the package and disposing of the removed band.

[Means for solving problems]

The present invention involves sandwiching one or two or more rows of bands that are stretched around a package between the two-pronged arm rods of a winding rod inserted from a right angle, cutting the bands, and moving the winding rod in one direction. A method for unpacking a package, which is characterized by rotating the package, winding a band around both arm levers, and removing the package from the package, and a forked arm lever extending parallel to the rotation axis used for this unpacking. This packing band winding rod is characterized in that the bases of both arm rods are thick, the ends are thin, and the outer surfaces in the longitudinal direction are provided with inclined surfaces.

〔Example〕

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

FIGS. 1 to 4 show an example of unpacking waste cardboard banded using a wire according to the method of the present invention. This package 1 is made by stacking a large number of waste cardboard sheets and banding three wires 3 around one circumference of the side surface to form a rectangular shape of, for example, InIX 1m x 2+++. In FIG. 1, after the package 1 is set in a fixed position, the winding rod 2 is lowered from above along one surface of the package 1. As shown in FIG. 5, this winding rod 2 has forked arm rods 2b, 2b integrally provided on a rotating shaft 2a directly connected to a rotary drive device 5. Both arm rods 2b, 2
b extends downward in parallel, the bases of both arm rods are thick, the lower ends are thin, and the outer surfaces in the longitudinal direction are provided with inclined surfaces. In Fig. 2, one arm rod 2 of the lowered winding rod 2
wires 3, 3.b stretched around the package 1; Insert the wires 3, 3 . Insert it between both arm rods 2b and 2b. Next, as shown in FIG. 3, a wire 3, which is stretched between one side of the package 1 into which the winding rod 2 is inserted, and the other side of the package 1,
3. ... is cut using a cutter 4 such as a rotary blade or a knife. Note that, prior to cutting the wire 3, the drive device 5 is activated to apply rotational torque to the winding rod 2. wire 3
,3. When ... is cut, the winding rod 2 rotates in one direction, and the wire 3 is wound into a coil while straddling both arm rods 2b, 2b. At the same time as the winding starts or after the winding is completed, the winding rod 2 is moved to the side of the package 1 as shown in FIG.
b, insert it into the base of 2b and pull up the winding rod 2, or push down the rod 6 and release both arm rods 2b.
, 2b, a coiled wire 3, 3 .・・・
・Scrape it off along the slope of the arm rods 2b, 2b and collect it in the container 7.

In the above example, the unpacking of a package of waste cardboard was explained, but it goes without saying that the package is not limited to this, but can also be unpacked in the same way for packages of kraft paper, rags, lumber, bark, leather, etc. .

In addition, the band hanging material is not limited to wire, but resin string,
Although it can be treated in the same way when ropes, ropes, etc. are used, it is suitable when using elastic materials that are difficult to remove and dispose of afterwards.

〔Effect of the invention〕

As described above, according to the method of the present invention, it is possible to mechanize and automate the unpacking work of banded packages, eliminate the dangers of conventional manual work, and also facilitate the disposal of removed bands. It can be carried out.

In particular, according to the present invention, the packing band is coiled around the arm of the winding rod, and can be easily removed from the arm in that form. Excellent effects can be obtained when applied to unpacking packages.
