Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a pulp unpacking device that improves the unpacking efficiency by cutting and removing wires binding the pulp without manual intervention. It is.

“Conventional technology” In general, paper manufacturing plants that do not have pulp manufacturing equipment
Sheet-like pulp transported from a pulp manufacturing plant is disintegrated by a pulper and then used as a raw material.

The sheet-like pulp is transported and stored as a so-called pulp bale l, which is wrapped in wrapping paper 1a and lb from above and below and tied vertically in a criss-cross pattern with wires lc, as shown in FIG. Therefore, when this pulp is put into a pulper for disintegration treatment, the wire 1c of the pulp bale l is removed, the wrapping paper 1a,
It is necessary to perform the removal work manually.

By the way, in recent years, the scale of paper manufacturing plants has increased significantly, and in order to efficiently supply pulp raw materials in such large-scale paper manufacturing plants, the unpacking of the pulp that has been mulched must be done automatically without manual intervention. There is a request to go to In order to meet this demand, a pulp unpacking method or a pulp unpacking device has been proposed in Japanese Patent Application No. 57-9752.

That is, this unpacking device aligns the pulp bale 1 being conveyed by the roller conveyor 2 in the width direction of the roller conveyor 2 by the centering device 3,
The wire 1c is cut by the wire cutting machine 4, the cut wire 1c is pulled out and removed by the wire removing machine 5, and the upper side is The wrapping paper la is removed, and the pulp bale 1 is reversed by the reversing machine 7 provided so as to surround the roller conveyor 2 described in 1iii, so that the lower wrapping paper 1b faces upward, and then the downstream ω direction of this reversing B7 is performed. The lower wrapping paper 1b is adsorbed and removed by a second suction device 6B installed in the second suction device 6B.

However, since the wires binding the pulp bale 1 have rigidity, the wires cannot be pulled out in a straight line by a simple pulling operation using the wire removal machine, and the wires may be bent in various shapes and pulled out. The problem is that it takes time to clean up the wire afterwards, and the structure of the wire remover becomes complicated because it supports forces in various directions that are applied to the wire remover when pulling out the wire.

By doing so, the wrapping paper covering the upper part of the pulp can be absorbed and removed.

Next, the operation of the unpacking device configured as above will be explained.

(i) The pulp bale l is conveyed in the X-axis direction by the roller conveyor 2, and is positioned at the center in the width direction of the roller conveyor 2 by a centering device (not shown).

(11) Stop the roller converter 2 and position the pulp bale I above the valve turner 8.

(iii) While bringing the contact plate 16 of the wire cutting machine 4A into contact with the side surface of the pulp bale 1, the cutting head 14
When the contact plate 16 moves in the X-axis direction, the contact plate 16 swings its head along the irregularities on the side surface of the pulp bale 16, and when the magnetic sensor 17 detects the metal wire lc, at the time of this detection After a certain timing, the cutting head 14 is stopped, and the cutter 18 is placed in a position facing the wire 1c.

(1v) Move the cutter 18 in the Y-axis direction and cut the wire IC as shown in FIG.

(v) Further repeat the above operations (iii) to 1v) to cut the two wire ICs.

(vl) Move the main frame 24 forward and the operating rod 4
0 is engaged with the guide frame 23, the swing arm 34 is rotated, and the brake is released, allowing the guide frame 23 and the main frame 24 to move together in the X-axis direction.

(vii) When positioning the cutting head I4 by moving the drawing head 37 laterally to bring the contact plate 16 into contact with the side surface of the pulp bale 1, and moving the guide flap 23 and the moving flap 38 in the X-axis direction. Similarly, the clamp 39 of the extraction head 37 is placed opposite the ear 1c.

(Japanese) As shown in Figure 9, the moving side guide roll,! 6
While lowering B, attach the wire IC to the clamp 39.

(IX) The wire IC pulled by the clamp 39 is guided by the guide plate 27 as shown in FIG. while being pulled outward in the Y-axis direction. At this time, the vertical force generated in ) due to the tension of the wire Ic is supported by the upper rail 25 via the guide roll 2611 and the guide frame 23, and therefore, the force other than the Y-axis direction is applied to the three clamps. There is almost no action, and a simple pull in the horizontal direction
You can pull out C. Further, the main frame 24 to which the clamp 39 is attached will not be lifted off the rail 35 due to vertical force being applied thereto.

(x) After repeating the operation (vl) or 1x) above and pulling out the two wires 1c, turn the valve turner
8 to horizontally rotate the pulp bale l over 90°, return to the above (...), cut the wire lc on the other side, and pull it out.

(xi) Operate the roller cono hair 2 to stop the valve hair l at a position between the reversing machine 7A and the wrapping paper removing machine 9.

(xii) Turn the wrapping paper removal R9 to the position shown by the chain line in FIG. 1 to remove the upper wrapping paper 1a, and then retract it to the position shown by the solid line.

(X...) Pulp bale 1 on feed 49 of reversing machine 7A
Hold a and rotate it vertically over 180°.

(xiv) Remove the wrapping paper 1h in the same manner as in (xii) above.

(XV) When the roller conveyor 2 is operated to send the pulp bale 12 further downstream [1111], the unpacking operation is completed.

Note that the configuration of the wire cutting machine, wire removing machine, reversing machine, or wrapping paper removing machine that forms part of the unpacking device is not limited to the one embodiment described above. For example, a reversing machine may be retracted from a position above the roller conveyor as long as it does not interfere with the operation of the wrapping paper removal machine, and a wrapping paper removal machine may be retracted from a position above the roller conveyor and removed from the wrapping paper removal machine. Any material that can absorb from above is sufficient.

"Effects of the Invention" As is clear from the above explanation, the present invention provides a pulp unpacking machine equipped with a wire removing machine that grabs the wire cut by the wire cutting machine and moves it horizontally toward the outside of the roller conveyor. , a guide frame that allows the wire removing machine to move freely in parallel to the conveying direction of the roller conveyor and is restricted from moving in the vertical direction, and a direction in which the wire is held in the same direction as the guide frame and in a direction perpendicular to the direction; and a drawing head that moves in both directions, and the guide frame is provided with a guide roll that winds the wire between the pulp bale and the drawing head and converts the drawing direction of the wire into a substantially horizontal direction. This makes it possible to pull out the pulp hale reliably while squeezing the wires that bind it, and also simplifies the mechanism that supports the pulling head by applying force only in the horizontal direction to the pulling head. This has the effect that it is possible to achieve the desired results.
