In the range of / 3 to 1/5 (set value), the conveyor 23 moves to the set distance (0.5 to 1.5 m) and stands by.
After that, similarly, the cutting of the take-up broke 22 is continued, and the cutting is continued by the instruction from the control device 25 until the total amount of the pulper charge is accumulated on the conveyor 23, and when the cutting of the take-up broke 22 is completed, The conveyor 23 is driven, the cutting broke is thrown into the pulper, and the disintegration of the broke is started. When the pulper is disintegrating the broke previously charged, the cutting broke stands by on the conveyor 23 until the disintegration is completed.

Next, the continuous operation method of the disassembling apparatus for the take-up broke according to the present invention will be described. When the pulper is of a continuous type, it is possible to continuously charge the pulper by changing the driving speed of the conveyor 23 or the cutting amount of the take-up broke according to the processing amount of the pulper. Further, when a disassembling machine for a take-up broke is installed directly above the pulper, the amount of broke cut can be varied according to the throughput of the pulper, and continuous direct charging can be performed.

As a blade for cutting the take-up broke 22, it is possible to use a rotary blade of a round blade, but there is an effect that there is no paper dust at the time of cutting, but due to the friction between the blade and the broke. Since the burnt paper is burnt, it may become a foreign substance when the raw material is recycled, or a fire may occur.
Further, there is a problem that a large amount of paper dust is generated in the rotary blade of the circular saw blade. Furthermore, in the case of a knife, the blade is frequently worn due to wear, and the processing time is long because the number of cuts in one run of the blade is small. Further, there is a problem in that a blade having only a sharpened tip will not be cut well and a large amount of waste paper pieces will be generated.

A preferred cutting tool used in the present invention will be described with reference to the drawings. 6 is a plan view of the blade, FIG. 7 is a front view of the blade, and FIG. 8 is a side view of the blade. Blades 28 are fixed to both ends of the pedestal 27 by brazing or the like, and the shape thereof may have a length 29 of 10 mm or more and a cutting edge angle 30 of 30.
If the angle is ˜50 °, and the angle is larger than 50 °, the life of the cutting edge is extended, but it is not preferable because the cutting power is increased, and if it is smaller than 30 °, the life is shortened, which is not preferable. Further, the rake angle 31 is in the range of 15 to 45 °, and if it is 15 ° or less, the life of the blade is shortened, and if it is 45 ° or more, the sharpness of the broke becomes poor, which is not preferable.

As the material of the blade 28, a material having high wear resistance may be used, and alloy tool steel materials SKS8 and SKD1 may be used.
1 etc. are preferable.

The bottom of the blade 28 is not particularly limited, but may be in a horizontal state, and a clearance angle 32 is provided at the bottom of the pedestal 27 so that the pedestal 27 and the take-up broke 22 do not come into contact with each other when the take-up broke 22 is cut. This is to make it difficult for the scraps of paper to come out and to prevent the increase in power by reducing the resistance. An escape angle 32 of 5 ° or more is provided to the extent that they do not come into contact with each other, and the bottom middle portion of the pedestal 27 is 1 mm or more. Space should be provided.

By providing the curved peaks 33 on both upper ends of the pedestal 27 to which the blades 28 are joined, it is possible to prevent scraps of scrap paper from coming out, and to smooth open the broken brokes.

Further, from the upper part of the pedestal 27, both pedestal side faces 34
By providing an air hole 35 penetrating therethrough and blowing compressed air between the cut brooke and the take-up broke, the cut broke can be easily dropped. Higher pressure of compressed air is preferable, but 0.5 to ¹ kg / cm ²
You can spray in the range of.

Further, the pedestal 27 is provided with a mounting hole 36 for mounting the pedestal 27.

[0028]

As described above, according to the present invention, the take-up broke disassembly amount (pulper charging amount) can be arbitrarily set depending on the processing capacity of the pulper regardless of whether the palper is a continuous type or a batch type. It is efficient because it can be used regardless of the size of the take-out block. Further, since the cutting amount for one reciprocation can be set according to the paper quality (rolling hardness, strength, etc.), the paper type is not selected. In particular, the manual work is performed only by setting the control device, and the winding broke can be disassembled very safely and in a short time in a labor-saving manner.
