Description

The present invention relates to a method for separating wires from a pulp bale, and in particular, to a method for separating wires from a pulp bale in which, after cutting the wires, the cut wires are peeled off from the pulp bale and then wound up.

The present inventors have previously disclosed a method for opening pulp bales (see, for example, patent documents).
This method of unpacking a pulp bale involves cutting the wire used to pack the pulp bale, and then winding up the cut wire without peeling it off from the pulp bale, thereby separating the wire from the pulp bale.

Patent No. 6570096

However, since pulp bales are generally imported and many days pass before the pulp is unpacked at the factory, the pulp bales can absorb a lot of moisture and expand, and the wire used to pack the pulp bales can become embedded in the corners of the pulp bales due to transportation, etc.
In such a case, when the cut wire is wound up after being cut, the motor overloads and the device stops, making it impossible to continue the work.

The present invention aims to provide a method for separating wires from pulp bales that eliminates the above problems.

A method for separating wires from a pulp bale according to one embodiment of the present invention will be described with reference to the drawings (Figs. 1 to 21).

(FIGS. 1 to 15)
1 shows a pulp bale 1 packed with wire, which is placed on a conveying surface 2. The conveying surface 2 is, for example, a roller conveyor.

The pulp bale wire separation device S is a device that separates wires from a pulp bale, and for example, has a main body 3 attached to the tip of a multi-axis robot arm that has multiple joints and can move freely in three-dimensional space, and has a clamp 4, a winding guide 5, and a cutter 6 attached to it.
The main body 3 , the clamp 4 , the winding guide 5 , and the cutter 6 are controlled by a control unit 100 .

In FIG. 2, the wire 11 is bound clockwise around the pulp bale 1 via a first corner R1, a second corner R2, a third corner R3 (see FIGS. 14 and 15), and a fourth corner R4.
Then, when the pulp bale 1 reaches a predetermined position on the conveying surface 2 as detected by an image sensor (not shown) attached to the main body 3, it stops, and the control unit 100 moves the main body 3 to the lower right position shown in Figure 5.

When the main body 3 is in the lower right position shown in Fig. 5 (for example, a position near the first corner R1), the control unit 100 causes the arm to descend. Then, the clamp 4, winding guide 5, and cutter 6 attached to the tip of the robot arm also descend. The clamp 4 grips and lifts the wire 11 (Figs. 3(a) and 3(b)), and the cutter 6 adjacent to the clamp 4 cuts the wire 11. That is, the wire 11 near the first corner R1 is cut (Figs. 9(c) and 11). One of the cut wires 11 is gripped and the wire 11 abutting the first corner R1 is moved so as to be peeled off from the first corner R1 and the second corner R2 (Figs. 9(c) and 9(d), 11, 12, and 13). After the movement, the cut wire 11 is wound up (Fig. 14), and the wire 11 is separated from the pulp bale 1 (Fig. 14).
The winding is performed by rotating the winding guide 5 located on the outside of the clamp 4, and the wire 11 is wound around the outer periphery of the winding guide 5.
In addition, the wire 11 wound around the outer periphery of the winding guide 5 is separated by lifting the winding guide 5 and abutting it against the stopper 8 located on the winding guide 5.

If the wires are cut and then wound up as is, the wires will get caught in the corners of the pulp bale, preventing the wires from being wound up. However, according to the above-mentioned method for separating wires from a pulp bale, the wires 11 near the first corner R1 are cut, one of the cut wires 11 is grasped and the wires 11 abutting the first corner R1 and the second corner R2 is moved so as to be peeled away from the first corner R1 and the second corner R2, and after the movement, the cut wire 11 is wound up, thereby preventing the above-mentioned problem from occurring.
After the wire 11 is separated from the pulp bale 1, the wire 11' above the wire 11 shown in Figure 5 is also separated from the pulp bale 1 in the same manner as the wire 11. This state is shown in Figure 9(c).

In the above-described embodiment, one of the cut wires 11 is grasped, and the wire 11 abutting against the first corner R1 and the second corner R2 is moved so as to be peeled off from the first corner R1 and the second corner R2. However, the present invention is not limited to this, and one of the cut wires 11 may be grasped, and the wire 11 abutting against the first corner R1 may be moved so as to be peeled off from the first corner R1.
In other words, this method of separating wires from a pulp bale is a method of separating wires from a pulp bale 1 that is packaged with wires 11, in which the wires 11 are bound clockwise around the pulp bale 1 via the first corner R1, the second corner R2, the third corner R3, and the fourth corner R4, and the wires 11 near the first corner R1 are cut, one of the cut wires 11 is grasped, and the wire 11 abutting the first corner R1 is moved so as to be peeled away from the first corner R1, and after the movement, the cut wire 11 is wound up and the wire 11 is separated from the pulp bale 1.
As described above, if the wire is cut and then wound up as is, the wire may get caught in the corner of the pulp bale and may not be able to be wound up. However, with this method of separating wires from a pulp bale, the wire is cut near the first corner R1, one of the cut wires 11 is grasped and the part of the wire 11 abutting the first corner R1 is moved so as to be peeled away from the first corner R1, and after the movement, the cut wire 11 is wound up, thereby preventing the above-mentioned problem from occurring.

(Figure 16)
In the above-described embodiment, the wire 11 is held at one point, but as shown in FIG. 16, it may be supported at two points.
In other words, this is a method for separating wires from a pulp bale 1 packaged with wires 11, and similarly to the above-described embodiment, the wires 11 are bound clockwise around the pulp bale 1 via the first corner R1, the second corner R2, the third corner R3, and the fourth corner R4.
As shown in FIG. 16( a ), the wire 11 is gripped at two points, the wire 11 between the two gripped points is cut, and one of the cut wires 11 and the other cut wire 11 are gripped and moved in a direction in which the one cut wire 11 and the other cut wire 11 are separated from each other. As shown in FIG. 16 ( b ), the one cut wire 11 is peeled off from the first corner R1, and the other cut wire 11 is peeled off from the fourth corner R4. As shown in FIG. 16 ( c ), the gripping of either the one cut wire 11 or the other cut wire 11 is released, and after the release, the cut wire 11 is wound up and separated from the pulp bale 1.
If the number wires are cut and then wound up as is, they may bite into the corners of the pulp bale, preventing them from being wound up. However, according to the method for separating number wires from a pulp bale in this embodiment, the number wires 11 are gripped at two points, the number wires 11 between the two gripped points are cut, one of the cut number wires 11 and the other cut number wire 11 are gripped separately, and the one cut number wire 11 and the other cut number wire 11 are moved in a direction separating them, so that the one cut number wire 11 is peeled off from the first corner R1 and the other cut number wire 11 is peeled off from the fourth corner R4, and the gripping of either the one cut number wire 11 or the other cut number wire 11 is released, and the cut number wire 11 is wound up after the release, thereby preventing the above-mentioned inconvenience from occurring.
In addition, "holding the wire 11 at two points and cutting the wire 11 between the two held points" specifically means that the two-point holding is performed, for example, by "the clamp 4 and the winding guide 5 shown in FIG. 3, and the clamp 4 shown in FIG. 3", and the cutting is performed by the cutter 6 shown in FIG. 4, and the wire 11 wound around the winding guide 5 can be cut by lifting the winding guide 5 of "the clamp 4, the winding guide 5, and the clamp 4 shown in FIG. 3" and abutting it against the stopper 8 shown in FIG. 17.

(FIGS. 17 to 21)
In the above-described embodiment, the wire 11 is cut, but as shown in Figs. 17 to 21, a plurality of wires 11, 12 may be cut.
That is, the wire has a first wire 11 and a second wire 12 arranged perpendicular to the first wire 11, and the first wire 11 is bound around the pulp bale 1 in a clockwise direction via the first corner R1, the second corner R2, the third corner R3, and the fourth corner R4, and the second wire 12 is bound around the pulp bale 1 in a clockwise direction via the first' corner R'1, the second' corner (not shown), the third' corner (not shown), and the fourth' corner R'4.
As shown in Fig. 21(a), the location where the first wire 11 and the second wire 12 intersect is A, and the first wire 11 and the second wire 12 near A are cut. That is, as shown in Fig. 17, clamps 4, 4' and cutter 6 adjacent to clamp 4' are provided along the first wire 11, and clamps 4", 4"' and cutter 6 adjacent to clamp 4"' are provided along the second wire 12, and the first wire 11 and the second wire 12 are cut. That is, as shown in Fig. 17, the first wire 11 is held by the clamps 4, 4', the first wire 11 is held by the cutter 6, and the second wire 12 is held by the clamps 4", 4"', and the second wire 12 is cut by the cutter 6' [Fig. 21(c)].
One of the cut first and second wires 11, 12 is gripped and moved so that the first wire 11 is away from the first corner R1 and the second corner R2, and the second wire 12 is away from the first' corner R'1 and the second' corner R'2 [FIG. 21(d)]. After being moved, the cut first and second wires 11, 12 are wound up and separated from the pulp bale 1.
The winding is performed by rotating the winding guide 5 located inside the clamps 4, 4', 4", and 4"', and the first and second wires 11, 12 are wound around the outer periphery of the winding guide 5.
In addition, the first and second wires 11, 12 wound around the outer circumference of the winding guide 5 are separated by lifting the winding guide 5 and abutting it against a stopper 8 (see Figure 14) located above the winding guide 5.
21(c) and 21(d), it is preferable to move in a direction toward corner B, which is closest to the intersection A of the first wire 11 and the second wire 12 among the four corners B, C, D, and E of the pulp bale 1 in a plan view, and then move downward. Since the moving distance can be reduced, the wires 11 and 12 of the pulp bale 1 can be separated more quickly.
Furthermore, if the wires are cut and then wound up as is, the wires may get stuck in the corners of the pulp bale, preventing it from being wound up. However, according to the method for separating wires from a pulp bale in this embodiment, the first wire 11 and the second wire 12 near A are cut, one of the cut first and second wires 11, 12 is grasped and moved so that the first wire 11 is away from the first corner R1 and the second corner R2, and the second wire 12 is away from the first' corner R'1 and the second' corner (not shown), and after the movements, the cut first and second wires 11, 12 are wound up, thereby preventing the above-mentioned inconvenience from occurring and allowing the first and second wires 11, 12 to be simultaneously separated from the pulp bale 1.

After the wires 11 and 12 have been separated from the pulp bale 1, the wires 11' above the first wire 11 and the wire 12' to the left of the second wire 12 shown in Figure 21(a) are also separated from the pulp bale 1 in the same manner as the first wire 11. This state is shown in Figure 21(h).
In other words, in a plan view, the location where wires 11' and 12' intersect is A', wires 11' and 12' near A' are cut, and one of the cut wires 11', 12' is grasped and moved so that one of the cut wires 11' is away from fourth corner R4, and one of the cut wires 12' is away from fourth corner R'4, respectively, and after the movements, the cut wires 11', 12' are wound up and the wires 11', 12' are separated from the pulp bale 1.

In the above-described embodiment, the first wire 11 and the second wire 12 in the vicinity of A are cut, and one of the first and second wires 11, 12 that have been cut is grasped and moved so that the first wire 11 that has been cut is away from the first corner R1 and the second corner R2, and the second wire 12 that has been cut is away from the first' corner R'1 and the second' corner R'2. However, the present invention is not limited to this, and one of the first and second wires 11, 12 that have been cut may be grasped and moved so that the first wire 11 that has been cut is away from the first corner R1, and the second wire 12 that has been cut is away from the first' corner R'1.
In other words, this method of separating numbered wires from a pulp bale is a method of separating numbered wires from a pulp bale 1 packed with numbered wires 11, 12, the numbered wires having a first numbered wire 11 and a second numbered wire 12 arranged perpendicular to the first numbered wire 11, the first numbered wire 11 being bound around the pulp bale 1 in a clockwise direction via a first corner R1, a second corner R2, a third corner R3, and a fourth corner R4, the second numbered wire 12 being bound around the pulp bale 1 in a clockwise direction via a first' corner R'1, a second' corner R'2, a third' corner R4, the The first and second wires 11, 12 may be bundled together via corners R'3 and R'4, and in a plan view, the location where the first wires 11 and the second wires 12 intersect is A. The first and second wires 11, 12 may be cut near A, and one of the cut first and second wires 11, 12 may be grasped and moved so that the first wire 11 is away from the first corner R1 and the second wire 12 is away from the first' corner R'1. After the movements, the cut first and second wires 11, 12 may be wound up and the first and second wires 11, 12 may be separated from the pulp bale 1.
As described above, if the wires are cut and then wound up as is, the wires may get stuck in the corners of the pulp bale, preventing it from being wound up. However, according to the method for separating wires from a pulp bale in this embodiment, the first wire 11 and the second wire 12 near A are cut, one of the cut first and second wires 11, 12 is grasped and moved so that the first wire 11 is away from the first corner R1 and the second wire 12 is away from the first' corner R'1, and after the movements, the cut first and second wires 11, 12 are wound up, thereby preventing the above-mentioned problem from occurring and allowing the first and second wires 11, 12 to be simultaneously separated from the pulp bale 1.
