Description

  The present invention relates to a paper supply device for supplying paper to a defibrating device for defibrating paper such as waste paper, and a defibration system including the paper supply device.

  In recent years, sludge dewatering (low water content dehydration) has been performed to regenerate sludge such as industrial wastewater and household wastewater as an auxiliary combustion material for a garbage incineration plant, for example. In the sludge dewatering equipment used for such treatment, the calorific value is improved by mixing and dewatering the sludge and the dewatering auxiliary material.

Attempts have been made to use defibrated used paper obtained by defibrating paper such as used paper with a defibrating device as a dehydration aid. For example, Patent Document 1 discloses a sludge concentration method in which waste paper is dissociated with a pulper and added to organic sludge, and further a polymer flocculant is added, followed by screen separation. A waste paper dewatering system that performs dewatering with a screw press-type dewatering device after addition is disclosed.
As a paper defibrating device, a pulper comprising a cylindrical dissolution tank for storing paper and a liquid such as water, and a rotary crushing blade installed at the bottom of the dissolution tank to crush the paper into fibers. It has been known. The pulper is an apparatus mainly used for raw material production of a papermaking apparatus, and performs defibrillation while shearing paper with the crushing blade by rotating the crushing blade at high speed (for example, Patent Document 3). reference).
There is also a defibrating device that throws paper and liquid stacked in a drum provided with a plurality of blades on its inner peripheral surface and rotates the drum to perform defibrating.

  There is a limit to the processing capacity of the defibrating device that puts paper and liquid stacked in a drum with a plurality of blades on the inner peripheral surface and performs defibration by rotating the drum at a time. The amount of paper that can be processed is limited. Therefore, when a large amount of paper is defibrated, it is necessary to manually input the paper after processing a predetermined amount of paper.

  Next, the control method and operation of the defibrating system 11 of the present embodiment will be described mainly with reference to FIG. The control flow of the defibrating system 11 includes a manual loading process and an automatic operation process.

(Manual loading process)
The manual loading step is a step of pushing paper into the plurality of paper storage units 7 by using the manual loading box 9 in a fixed amount.
First, the operator switches the mode selector 38 to place the control device 59 in the manual loading mode. During the manual loading mode, the control device 59 monitors whether or not the limit switch LS2 is turned on when the push plate 29 is “closed”, that is, when the push plate 29 is in the push-off position.
And the control apparatus 59 which detected the output of limit switch LS2 stops the endless chain 6. FIG. That is, the control device 59 performs control so that the endless chain 6 is not rotated except when the push plate 29 is in the open state (the push plate 29 is in the return position and the limit switch LS1 is ON).

The control device 59 detects the signal of the loading start switch 39 as a loading request for the paper storage unit 7. Then, the control device 59 that has detected the signal of the loading start switch 39 moves the paper container 7 to the position of the manual loading box 9. This loading position is detected by the limit switch LS3. That is, the control device 59 moves the paper storage unit 7 until it detects a signal from the limit switch LS3.
Next, the operator stacks papers between the rail walls 28 of the manual loading box 9 and then moves the push plate 29 between the rail walls 28 to store the papers in a stacked state. Housed in part 7.

  When the paper is stored in the paper storage unit 7, the loading start switch 39 is pressed. The control device 59 moves the paper container 7 that is not loaded with paper to the position of the manual loading box 9. This operation is repeated and the paper is stored in the paper storage unit 7 in a stacked state.

The operator switches the mode selector 38 to set the control device 59 to the automatic operation mode. In the automatic operation mode, the control device 59 detects the signal of the limit switch LS2 as an automatic operation stop request. That is, the control device 59 confirms the open / close state of the push plate 29 and does not shift to the automatic operation mode when the push plate 29 is closed.

  Then, by switching to the automatic operation mode, the control device 59 moves the first paper storage unit 7 in which paper is stored to the position of the discharge means 8. This discharge position is detected by the limit switch LS4.

  At this time, if the limit switch LS5 for monitoring the state where the cylinder 31 is fully pushed is “ON”, the control device 59 stops the operation. The limit switch LS6 is a limit switch that is “ON” when the cylinder 31 is in the return cut-off position (fixed position) regardless of the manual loading mode or the automatic operation mode.

  Next, after confirming that the drum 70 of the defibrating device 62 can input paper, the control device 59 operates the flap 34 with chute to input paper into the drum 70. At this time, the control device 59 can refer to the limit switch LS7 which is “ON” when the flap 34 with chute is turned up and the limit switch LS8 which is “ON” when the flap 34 with chute is turned down. .

  The drum 70 is provided with a limit switch LS <b> 9 that is turned “ON” when a plurality of blades provided on the inner peripheral surface of the drum 70 are not positioned at the bottom of the drum 70. The control device 59 confirms that the LS 9 is “ON” when the paper is input and when the paper is discharged after defibration.

Next, the control device 59 rotates the drum 70, whereby the paper is agitated and defibrated. The paper is defibrated by strong turbulent flow generated between the inner peripheral surfaces of the drum 70 and impact force caused by dropping.
The drum 70 is provided with a limit switch LS11 that is turned “ON” when the inlet 70a of the drum 70 is facing upward. When the paper is agitated / defibrated, the control device 59 monitors the output of the limit switch LS11 and performs defibration when the limit switch LS11 is "ON".

Next, the control device 59 discharges the defibrated paper from the drum 70.
The drum 70 is provided with a limit switch LS10 that is "ON" when the insertion port 70a of the drum 70 is facing downward. When discharging the paper, the control device 59 monitors the output of the limit switch LS10, and discharges the paper from the drum 70 when the limit switch LS10 is “ON”.

And the control apparatus 59 implements the defibration of the following paper accommodating part 7. FIG. That is, the paper stored in the next paper storage unit 7 is put into the defibrating device 62, defibrated by the defibrating device 62, and the defibrated paper is discharged to the defibrated old paper storage tank 52. To do.
Then, the automatic operation process is continued until the defibration of the papers in all the paper storage units 7 in which all the papers are stored is completed.

  Further, since the paper accommodating portion 7 is always located on the outer peripheral side of the endless chain 6, the pushing operation of the discharge means 8 is performed by the presence of the endless chain 6 regardless of the shape of the endless chain 6 orbit. Will not be hindered.

  Further, since the track of the endless chain 6 extends in the vertical direction, space can be saved as compared with a conveyor system that moves paper in the horizontal direction.

  Further, in the automatic operation process, the control device 59 automatically disentries until the disentanglement of the papers stored in all the paper storage units 7 is completed, so that the operator arranges in the device. Time can be shortened.

  Further, when the paper is collected inside the paper storage unit 7 by the first guide 21 and the second guide 25, the paper collapses even when the paper storage unit 7 is rotated by the travel of the endless chain 6. Can be prevented.

  Moreover, since the paper accommodating part 7 is fixed by a pair of links which have the predetermined length which comprises the endless chain 6, fixation can be made stronger.
