Abstract

PURPOSE:To unpackage a package by pressing a bundled package on slits and separating elements of the package from a bundling member. CONSTITUTION:A package is formed of contractable elements a, a,... such as corrugated cardboard and newspaper which are arranged in the lateral direction and bundled and further tied up in a prescribed form by winding a band 6 around a body. On upper and lower surfaces of the package 3 which are not tied up by the band, end edges of the elements a, a,... appear in layers. The package 3 is carried onto a grid 1 and positioned so that a line direction of the elements a, a,... makes right angles with an opening direction of slits 4, 4,... of the grid 1. Next, when a processor 2 is started to make a pushing pad 5 descend so that the upper surface of the package 3 is pressed, the element (a) on the slit 4, which is not supported at all, drops down through the slit 4. Immediately, the rest of the elements a, a,... which are deformed by this drop down successively inside the slits 4, 4,... and are separated from the bundle band 6. The bundling band 6 is left on the grid 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for unpacking a banded package.

[Conventional technology]

Banding as a packaging method is widely used in various fields. For example, industrial cardboard materials such as used cardboard and craft paper are tied together using bands such as wire, string, or rope, and sent to factories after being kept in a certain shape. There was no other way to do this, so workers had to use nippers to cut the band and remove it from the package.

[Problem to be solved by the invention 1] Generally, unpacking work sites are often areas where forklifts operate, and it is difficult for workers to manually remove bands, especially wires, from packages in such environments. It is dangerous work. Furthermore, the wires removed from the package must be bundled against the stretching force, which 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.

By the way, when recycling old cardboard, old newspapers, old magazines, etc. as industrial materials, the materials are not tied together in a disorderly manner, and because the materials are compressible, they are usually layered in the same direction. They are lined up and bundled, tied with a band around the body, and held in a fixed shape.

An object of the present invention is to provide a method and apparatus for unpacking a package by effectively utilizing the form of this type of package.

[Means for Solving the Problems] In order to achieve the above object, in the unpacking method according to the present invention, a package bound with a binding member is pressurized on a slit to separate the material of the package from the binding member. This is a method for unpacking a package, in which the binding member is a band such as a string, rope, or wire, and the package is made by bundling compressible materials such as cardboard or waste paper in layers in the same direction, and wrapping them around the body. The slits are formed between the lattices that support key points of the package, and the slits are formed between the lattices that support the key points of the package. One side is supported on a lattice and the other side is pressed down to forcibly extract the material of the package from the binding member through the slit between the lattices.

The present invention also provides an unpacking device for a package that has a grid and a pressurizing device that realizes the above method, wherein the grid supports the package bound in a fixed shape by passing a band around the body. The slit is a gap formed between the lattices and allows compressible materials such as cardboard and waste paper that make up the package to pass through, and the pressurizing device is placed on the lattice. Press down one side of the package,
The material of the package is forcibly removed from the band through the slit.

[Effect]

The package is carried onto the lattice with the direction in which the materials are arranged perpendicular to the opening direction of the slits in the lattice.

The press pad of the pressurizing device is lowered from above the package and its negative side is pressed. The material of the package is pushed out into the slit of the grid under the pressure of the pad, and a part of it falls through the slit, destroying the shape of the package. As a result, the remaining material also falls from the slit b under its own weight, leaving only the band on the lattice.

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

In FIG. 1, the device of the present invention consists of a combination of a grid 1 and a pressurizing device 2. In FIG.

The grid 1 supports the package 3, and the grid I is
A slit 4 through which materials a, a, ... of the package 3 pass.
,4. ... are formed in parallel.

Therefore, the grid 1 has the strength to support the package 3 and withstand the pressure of the pressurizing device 2, and the slit intervals are wide, and the lengths of the slits are the same as those for the individual materials a, a,... It must be longer than the total length of... The pressurizing device 2 is a press machine, and has a press pad 5 installed above the grid 1 so as to be movable up and down.

FIG. 2 shows an example of a package 3 to be unpacked using the apparatus of the present invention. The package is made by arranging and bundling compressible materials a, a, . The edges of each material a, a, . . . appear in layers on the upper and lower surfaces of the package 3 that is not covered with a bundt.

The package 3 shown in FIG. 2 is carried onto the grid 1 shown in FIG.

When transporting the package 3, each slit 4, 4 of the grid 1
．． Each material a with respect to the opening direction of...

The packaging pair 3 is placed on the grid 1 with alignment so that the directions of the rows a, . . . are perpendicular to each other. Since the package 3 is tied tightly with the band 6 and kept in a fixed shape, it is attached to the grid 1 as it is.
held on top.

Next, the pressurizing device 2 is activated, the suppressing pad 5 is processed, and the upper surface of the package 3 is pressurized. The package 3 receives compressive force from above, and the material a above the slit 4 is unsupported, so
It falls through slit 4 and immediately loses its shape.
The remaining materials a, a, . . . are also successively inserted into slits 4, 4, etc. as shown in Fig. 3. It falls down inside and is separated from the binding band 6.

The cable ties 6 are left on the grid 1.

In the above embodiments, the unpacking of a cardboard package has been described, but the present invention is not limited to this, and it goes without saying that packages of kraft paper, newspaper, magazines, tree bark, etc. can also be unpacked in the same way.

As the band 6, wire, resin string, rope, rope, etc. can be used. The raw materials a, a, .

[Effects of the Invention] As described above, according to the present invention, it is possible to unpack a package placed on a grid simply by mechanically lowering it by utilizing the characteristics of the material of the package and the bundling method. The material of the packaging body and the cable tie can be separated using the following steps.

Therefore, according to the present invention, it is possible to mechanize and automate the unpacking work of banded packages, eliminate the dangers of conventional manual work, and easily dispose of removed bands. It has the effect of
