Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wound residual paper processing apparatus that removes a wide (5 meters) remaining paper (diameter: 1.2 meters) wound on a spool from the spool.
[0002]
[Prior art]
In a paper mill, a wide base paper wound on a spool by a winder of a paper machine is cut into a predetermined width by a plurality of slitters and wound on a plurality of paper tubes (cores) having a predetermined width. A paper roll of a predetermined width is manufactured.
The wide remaining paper remaining on the spool in the above manufacturing process is reused as a paper raw material and is removed from the spool and collected in the manufacturing process.
[0002]
Conventionally, as a means for removing the remaining wide paper remaining on the spool, the spool is rewound and the remaining paper is taken out. With this means, it takes time to rewind the long paper, and the rewound long paper becomes bulky. There are drawbacks.
In addition, as another removal means, the remaining paper is sequentially cut in the spool axis direction by manual cutting using tuna, etc., and the incision and removal are performed. It was hard work.
[0003]
[Problems to be solved by the invention]
An object of the present invention is to provide a rolled-up residual paper processing apparatus that improves the above-mentioned conventional problems and can be recovered in a short time without using human power and with reduced labor without bulking the removed residual paper.
[0004]
[Means for Solving the Problems]
A rotary blade 31 that can reciprocate over the entire length of the remaining paper P in the paper width direction of the remaining paper P wound around the spool 2 and can be cut in the radial direction of the remaining paper P. The remaining paper is incised and peeled off by a plurality of layers.
[0005]
The base plate 23 on which the rotary blade 31 is installed is provided with scissors 36 and 36 ′ that can be projected and retracted vertically on both sides of the rotary blade 31, and the scissors are inserted into the cut portions of the rotary blade 31 to separate the remaining paper. It is characterized by improving.

[0015]
Reference numeral 52 denotes a cutting paper guide device, and two guide plates 54, 54 ′ slightly longer than the paper width in the width direction of the remaining paper P on the upper side of the square frame 53 installed below the remaining paper P. Has a structure in which the upper part is expanded and attached. (See Figs. 1 and 2)
[0016]
Next, the operation of the apparatus according to the present invention will be described.
First, the remaining paper P wound up on the spool 2 is conveyed by an overhead crane or the like, and both end bearing boxes R and R ′ of the spool 2 are placed on the spool placing stands 3 and 3 ′. Due to the synchronous operation of the geared motors 6 and 6 ′, the carts 5 and 5 ′ travel from the standby position and are stopped at the working position of the rotary blade 31.
[0017]
The rail 10 in which the beam 11 is laid on the vertical frame portions 7 ₁ and 7 ₁ ′ of the portal frame 7 through the gear box 17 and the power transmission shafts 19 and 19 ′ screw jacks 13 and 13 ′ by the operation of the AC servo motor. 10 ′ is slid and guided by the linear blocks 12 and 12 ′ to be lowered from the standby position, is lowered to the working position of the rotary blade 31 installed on the beam 11, and is stopped at the position.
[0018]
Therefore, by operating the geared motor 27, the base plate 23 driven by the chain 29 and the chain 29 by the rotation of the chain wheels 28 and 28 ′ causes the beam through the sliders 23 ₁ , 23 ₁ ′, 23 ₂ and 23 ₂ ′. rail 22 ₁ which is laid 11, 22 ₂ to the traveling base plate 23 by counterclockwise rotation of the geared motor 27 in FIG. 1 travels in the direction of the arrow.
[0019]
Since the rotary blade 31 is installed on the base plate 23 so as to be freely rotatable, the rotary blade 31 cuts the remaining paper P from the right end to the left end over a plurality of layers while rotating in contact with the remaining paper P. In FIG. 2, the cut paper is cut left and right in FIG. 2, and when the paper is dropped, the paper is guided by the guide plates 54 and 54 ′ of the cut paper guide device 52 and discharged. When the rotary blade 31 cuts to the left end, the AC servo motor 14 is operated to lower the beam 11 by the cutting stroke of the rotary blade 31 and the geared motor 27 is rotated in the reverse direction, so that the base plate 23 travels in the opposite direction. The cutting operation by the rotary blade 31 is continued. By repeating the above operation, the cutting operation is performed up to the vicinity of the spool 2.
[0020]
In the above cutting operation, if the remaining paper is not sufficiently separated only by cutting the rotary blade 31, the remaining paper is separated by using the scissors 36 and 36 ′ installed on both sides of the rotary blade 31. It can be done effectively.
That is, the paper layer is surely separated by inserting the air cylinder 37 or 37 ′ into the paper layer cut by the rotary blade 31 with a thickness larger than the blade thickness of the rotary blade. be able to.
[0021]
When the scissors 36 and 36 'are on the front side in the moving direction of the rotary blade 31, the front end of the scissors is retracted to a position higher than the front end of the rotary blade, and is lowered below the front end of the rotary blade only when coming to the rear side. Is inserted into the notch of the rotary blade. Further, although not shown, the paper layer can be surely separated by blowing air from the air nozzle toward the cut portion of the paper layer.
[0022]
When the operation of separating the remaining paper by the rotary blade 31 is completed, the remaining paper slightly wound around the spool 2 is unwound from the spool by the operation of the spool driving device 38 and removed. That is, when the cylinder 42 is operated, the cylinder rod 48 is extended while the cylinder head 43 is guided by the guide members 49 and 49 ′, and the base 44 is raised along the guide rails 41 and 41 ′. When the rubber tire 46 comes into contact with the friction wheel W attached to the tip end portion of the spool shaft, the cylinder stops, and the base 44 is placed at this position. Therefore, the friction wheel W is driven by operating the geared motor 45 to drive the rubber tire, and the remaining paper wound around the spool 2 is rewound and completely removed from the spool.
Each of the above steps can be easily automatically operated by a known automatic control technique.
[0023]
Although not shown, a rotary blade 31 is adjacent to two of the first rotary blade and the second rotary blade in the advancing direction of the blade, and a drive mechanism that drives each rotary blade in the vertical direction with an air cylinder or the like, respectively. And a device that performs cutting work by adjusting the cutting depth with a driving device such as an air cylinder so that the cutting of the trailing rotary blade is deeper than the leading rotary blade. Work time can be greatly reduced.
[0024]
【The invention's effect】
According to the present invention, since the remaining paper removal work wound around the spool can be performed by mechanical equipment without human power, the work can be performed quickly and the remaining paper can be processed without being bulky, and can contribute to labor saving. The effect of this is achieved.
