An inflow port 46, an airflow outlet 47 provided at the upper end of the main body 45, and a discharge port 48 provided at the lower portion of the main body 45 are provided.

  The first duct 17 is connected between the discharge port 41 of the dispersion cyclone 25 and the inlet 46 of the discharge cyclone 19, whereby the discharge cyclone 19 and the paper material input unit 18 are connected to the first duct 17. Connected through.

  As shown in FIGS. 2, 3, and 9, the blower 20 includes a suction port 50 that sucks air and a discharge port 51 that discharges the sucked air. A circular tube hollow second duct 57 is connected between the discharge port 51 of the blower 20 and the air flow inlet 42 of the dispersing cyclone 25.

  A third duct 58 having a hollow circular tube is connected between the air flow outlet 47 of the discharge cyclone 19 and the suction port 50 of the blower 20. The first to third ducts 17, 57, 58 are flexible and flexible tubes made of rubber or the like. In addition, an outside air suction portion 52 is formed on the suction side of the blower 20 to compensate for an insufficient discharge flow rate of air discharged from the discharge port 51.

  As shown in FIGS. 2 and 7, the measuring unit 11 includes a receiving tray 54 that can swing up and down around a support shaft 53, and a swinging device 55 that swings the receiving tray 54 between a receiving position C and a loading position D. And a weight detector 56 for detecting the weight of the paper material 7 received on the receiving tray 54.

Hereinafter, the operation of the above configuration will be described.
As shown in FIG. 2, when the blower 20 is driven, the air discharged from the discharge port 51 of the blower 20 flows through the second duct 57, passes through the dispersion cyclone 25, and passes through the first duct 17. It flows into the third duct 58 through the discharge cyclone 19, and is sucked into the suction port 50 of the blower 20 from the third duct 58. Thereby, the air discharged from the discharge port 51 of the blower 20 circulates in the first to third ducts 17, 57, 58 and returns to the suction port 50 of the blower 20. An airflow 63 that flows through the first duct 17 through the cyclone 25 is generated.

  As shown in FIGS. 4 and 5, when the electric motor 59 is driven and the drive gear 60 is rotated, both the delivery rollers 30 and 31 are rotated in directions A and B opposite to each other. As a result, the paper material 7 in the hopper 23 is sandwiched between the delivery rollers 30 and 31 and is drawn downward from the discharge port 27 of the hopper 23. At this time, the paper material 7 is unwound from the supply port 40 of the dispersion cyclone 25. It is sent out into the main body 39.

  At this time, as shown in FIG. 6, the air that has flowed into the main body 39 from the air flow inlet 42 of the dispersing cyclone 25 becomes a swirl flow E (vortex flow) from the discharge port 41 to the upstream side in the first duct 17. The paper material 7 that has flowed out and is fed into the main body 39 of the dispersing cyclone 25 by the feed rollers 30 and 31 is dispersed by the swirling flow E and is upstream of the first duct 17 from the discharge port 41 together with the air. It is thrown into. As a result, the paper material 7 does not become a lump, but is reliably unwound by the delivery rollers 30 and 31 and dispersed by the dispersing cyclone 25, and is fed upstream in the first duct 17. Accordingly, it is possible to prevent the paper material 7 from being put into the first duct 17 in a lump state, and to prevent the lump of the paper material 7 from being stagnated in the first duct 17 without being transferred. can do.

  As shown in FIG. 2, the paper material 7 put in the upstream side in the first duct 17 in this way is carried on the air flow 63 in the first duct 17 from the upstream side to the downstream side, and is discharged. As shown in FIG. 8, it flows into the main body 45 from the inlet 46 of the cyclone 19 and is drawn to the outside by the swirl flow F (vortex) generated in the main body 45 and descends by gravity, as shown in FIG. As described above, it is discharged from the discharge port 48 to the tray 54 of the measuring unit 11.

  Further, the air flowing into the main body 45 from the inlet 46 of the discharge cyclone 19 together with the paper material 7 flows into the swirl flow F in the main body 45 to the vicinity of the discharge port 48, and then the main body 45. Ascending airflow along the axial center of the airflow flows into the third duct 58 from the airflow outlet 47 and is sucked into the suction port 50 of the blower 20 through the third duct 58.

  In this way, the paper material 7 is carried on the airflow 63 in the first duct 17 and transferred to the measuring unit 11 at the target location. Therefore, as shown in FIG. It is possible to arrange the paper material input unit 18 at a location away from the discharge cyclone 19. Therefore, the arrangement position of the paper material input portion is not limited to the position just above the discharge portion as in the conventional case, and the degree of freedom in design is increased.

  Further, when the arrangement position of the paper material input unit 18 with respect to the arrangement position of the discharge cyclone 19 is changed, the first to third ducts 17, 57, 58 bend (bend), so the paper material input unit 18 and the discharge material are discharged. With the cyclone 19, the blower 20, and the ducts 17, 57, and 58 connected to each other, the paper material input unit 18 can be easily moved with respect to the discharge cyclone 19. Thereby, a layout can be rearranged easily and freely.

  Further, as shown in FIG. 4, when the paper material 7 is sandwiched between the delivery rollers 30 and 31 and sent out, the outer peripheral member 36 of the delivery rollers 30 and 31 is reduced in the radial direction, so that the paper material 7 is forced. Can be delivered smoothly and reliably.

  When the weight of the paper material 7 discharged to the tray 54 of the measuring unit 11 is detected by the weight detector 56 and reaches a specified weight (an example of a specified measurement value, for example, 100 g), When the moving device 55 is activated, the tray 54 swings from the receiving position C (see the solid line in FIG. 2) to the loading position D (see the phantom line in FIG. 2), and the paper material 7 on the tray 54 moves to the pulper device 10. It is thrown.

  Thereafter, the paper material 7 is disaggregated in the pulper device 10 to produce a pulp suspension 9, the pulp suspension 9 is deinked in the deinking device 3, and the wet paper obtained by papermaking is dried in the papermaking device 4. Then, the finished paper 5 is cut into a predetermined size to obtain the recycled paper 14.

  As shown in FIGS. 4 and 5, when both the delivery rollers 30 and 31 are rotating, the outer peripheral surfaces of both the delivery rollers 30 and 31 are in contact with each other, and both end portions of the delivery rollers 30 and 31 are in contact with each other. And the plate portion 29a is closed by the first closing member 37, and the gap between the outer peripheral surface of the delivery rollers 30 and 31 and the side plate portion 29b is closed by the second closing member 38. It is possible to prevent a part of the air that has flowed into the dispersion cyclone 25 from 57 from flowing back into the hopper 23 from the inside of the delivery cyclone 25 from the bottom to the top. It is possible to prevent the paper material 7 in the hopper 23 from being scattered.

  In addition, when a part of the air flowing into the discharge cyclone 19 from the first duct 17 is discharged from the discharge port 48 together with the paper material 7 without flowing to the third duct 58, the air flows into the suction port 50 of the blower 20. The suction flow rate that is sucked is smaller than the discharge flow rate that is discharged from the discharge port 51. In this case, since the outside air is sucked from the outside air suction part 52 to the suction side of the blower 20, the shortage of the discharge flow rate discharged from the discharge port 51 is compensated.

  In the first embodiment, both the delivery rollers 30 and 31 are provided with the outer peripheral member 36 so as to be flexible in the radial direction. However, only one of the delivery rollers has the outer peripheral member 36. By providing, you may have the softness | flexibility which can be expanded / contracted to radial direction.

  In the first embodiment, the roller main body 34 composed of the core member 35 and the outer peripheral member 36 formed of a flexible material is used. However, the roller main body 34 is not limited to this configuration. You may use the roller main body 34 comprised with the rubber | gum which has a hollow part. Even with such a configuration, it is possible to obtain both delivery rollers 30 and 31 having flexibility that can be expanded and contracted in the radial direction.

(Second Embodiment)
Hereinafter, a second embodiment of the present invention will be described with reference to FIGS.
The delivery means 24 includes a casing 29, a pair of rotatable opening / closing means 65 provided in the casing 29, and a rotation driving device 32 that rotates both opening / closing means 65 in opposite directions A and B. .

  The opening / closing means 65 feeds the paper material 7 from the inside of the hopper 23 to the upstream side of the first duct 17 while opening and closing the supply path 43. And a rotating body 66. By rotating both rotating bodies 66 in opposite directions A and B, as shown in FIGS. 10 and 11, both rotating bodies 66 open and close the supply path 43 according to the rotation angle. FIG. 10 shows a state where both rotating bodies 66 open the supply path 43, and FIG. 11 shows a state where both rotating bodies 66 close the supply path 43.

Hereinafter, the operation of the above configuration will be described.
When the electric motor 59 is driven to rotate the drive gear 60, both rotating bodies 66 rotate in opposite directions A and B, and the supply path 43 is repeatedly opened and closed with this rotation. The paper material 7 in the hopper 23 is sandwiched between the rotating bodies 66 and drawn downward from the discharge port 27 of the hopper 23. When the supply path 43 is opened as shown in FIG. It passes through the main body 39 from the supply port 40 of the dispersion cyclone 25.

  Further, as shown in FIG. 11, when the supply path 43 is closed, the paper material 7 in the hopper 23 is not sent out. Thus, by rotating both the rotating bodies 66 and repeatedly opening and closing the supply path 43, the paper material 7 stored in the hopper 23 does not become a lump but is finely divided and broken into the dispersion cyclone 25. Sent out.

  In the second embodiment, each rotating body 66 has four rectangular flat plates. However, the rotating body 66 is not limited to four, and there are a plurality of sheets other than four or a single sheet. You may do it.

(Third embodiment)
In the first embodiment, the dispersing cyclone 25 is provided as an example of the dispersing means as shown in FIG. 2, but as another example of the dispersing means, as shown in FIGS. A passage 70 may be provided. The dispersion passage 70 includes an inclined duct portion 71 and a connection duct portion 72.

  The inclined duct portion 71 is a square cylindrical member having both upper and lower ends opened, and the lower portion is inclined downstream with respect to the upper portion. The upper end portion of the inclined duct portion 71 is attached to the lower portion of the delivery means 24.

  The connection duct portion 72 is a square box-shaped member having a hollow portion therein, and has an inlet 72a and an outlet 72b. The first duct 17 is connected between the discharge port 72 b of the connection duct portion 72 and the inlet 46 of the discharge cyclone 19. The second duct 57 is connected between the discharge port 51 of the blower 20 and the inlet 72 a of the connection duct portion 72.

Hereinafter, the operation of the above configuration will be described.
The air discharged from the discharge port 51 of the blower 20 flows through the second duct 57, passes through the connection duct portion 72, and flows through the first duct 17. As shown in FIG. 15, the paper material 7 sent into the dispersion passage 70 by the sending means 24 falls in the inclined duct portion 71 and flows into the connecting duct portion 72, and flows in the connecting duct portion 72. The air that flows from the inlet 72 a to the outlet 72 b joins, is introduced into the first duct 17, and is carried along the airflow 63 through the first duct 17.

  At this time, since the lower portion of the inclined duct portion 71 is inclined to the downstream side with respect to the upper portion, the paper material 7 sent out by the sending means 24 once hits the inner side surface 71a of the inclined duct portion 71, and the inclined duct portion 71 The part 71 is dropped. Further, part of the air flowing into the connection duct portion 72 from the inlet 72a flows into the inclined duct portion 71, reverses in the inclined duct portion 71, returns to the connection duct portion 72, and flows to the discharge port 72b. Therefore, a spiral airflow 63a is generated, and the paper material 7 is diffused by the spiral airflow 63a. As described above, the paper material 7 does not become a lump by being hit by the inner surface 71a of the inclined duct portion 71 and being diffused by the swirl airflow 63a, and is reliably dispersed in the first duct 17. To the upstream side.

  In each of the above embodiments, the shredded waste paper 7 is used as the paper material 7. However, the present invention is not limited to this.
