An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, 12 is a shredder for shredding the waste paper P and the like. The shredder 12
Is formed into a box-shaped body composed of a bottom plate 12a, a side plate 12b, and an upper lid plate 12c, and a door 12d is provided at the front part to be openable and closable. A base plate 14 is attached to the inner peripheral portion of the shredder 12. The inside of the shredder 12 is divided into an upper space 13 located above the base plate 14 and a lower space 15 located below the base plate 14. In the upper space portion 13, a pair of vertical cutting cutters 1
A shredder 20 is provided which is composed of 6, 16 and a horizontal cutter 18 provided below the vertical cutter.

Reference numeral 22 is a motor for driving the shredded portion 20. The motor 22 is provided on a substrate 24. 26 is a dust-proof cover for covering the motor 22. Reference numeral 28 denotes a control box that houses a control mechanism that controls the drive of the shredder 12, and is also covered with a dustproof cover 30.

In the lower space 15 of the shredder 12, a waste storage box 32 is arranged on the bottom plate 12a via a movable plate 34 which is vertically movable. Reference numeral 33 is a scattering prevention frame which is attached so as to cover the entire circumference of the lower surface of the base plate 14 and acts so as not to scatter the shredded scrap D from the scrap storage box 32.

2 and 3, reference numeral 36 is a bearing plate provided on the side edge of the bottom plate 12a. 38 is
It is an auxiliary plate provided on the side edge of the moving plate 34. One end of an arm plate 40 is rotatably attached to the auxiliary plate via a shaft 42. The other end of the arm plate 40 is rotatably attached to the bearing plate 36 via a shaft 44. Reference numeral 46 is an insertion hole formed in the front end portion of the moving plate 34. Reference numeral 48 is an inverted J-shaped hook means attached to a side edge portion inside the door 12d.

In FIG. 1, reference numeral 50 is a fan mechanism provided with one or a plurality of blades 50a, which is a smoothing means for smoothing shreds. 52 is the fan mechanism 5
It is a motor for rotating 0 and is mounted on a support plate 54 attached to the substrate 24. 56 and 58
Is a first waste sensor and a second sensor for detecting shredded waste. The first sensor is a shredder D from the shredder 20.
Is installed at position A (Fig. 7) where
The second sensor is installed at a position B (FIG. 7) opposite to the installation position of the first sensor 56.

The number of blades 50a attached to the fan mechanism 50 may be one or more or a plurality of blades.
There is no particular limitation, but four is preferable. The shape of the blade 50a is not limited to any particular shape as long as it has a function of smoothing out shredded dust, but as shown in FIG. 5, the efficiency of the smoothing operation is improved by using a blade having a downwardly inclined shape. Also, the blade 50a
It is also possible to attach a guard member (not shown) to the above to prevent danger.

The operation of the above structure will be described. Shredded debris D such as waste paper shredded by the shredder 20 of the shredder 12 falls and accumulates in a waste storage box installed below the shredded part. The above-mentioned waste leveling means, that is, the usage mode of the fan mechanism 50 is not uniform, and various usages are possible. For example, the fan mechanism 50 is rotated at the same time as the shredding of waste paper or the like is started, and the fan mechanism 50 is stopped at the same time as the shredding is completed. In this case, the shredded dust shredded by the shredder 20 falls downward between the blades 50a of the fan mechanism 50 and is housed in the waste housing box. This falling state is
As the blades 50a rotate, the blades 50a are uniformly dropped in the waste container.

Further, when a large amount of shredded chips reaches the position of the fan mechanism, the shredded chips are made uniform by the rotation of the blades 50a. When the second waste sensor 58 detects the shredded waste D, the waste storage box 32 is full of shredded waste D, and the shredding operation is stopped to remove the waste storage box 32. . After the shredding work is stopped, the fan mechanism 50 is preferably rotated for a short time to perform the final scraping operation.

As another usage mode of the fan mechanism, the first waste sensor 56 detects that the waste storage box 32 is full of shredded waste D and stops the shredding work. Next, the fan mechanism 50 is rotated to carry out a scraping operation. When the detection by the first waste sensor 56 is lost, the shredding work is started. This operation is repeated, and the shredding work is stopped when the second waste sensor 58 detects waste. After that, the waste storage box is taken out as described above. Even in this case, the shredding work and the scraping-out work can be performed at the same time.

The debris storage box 32 is placed on the moving plate 34 located on the upper surface of the bottom plate 12a, and when the door 12d is closed, the hook means 48 of the door 12d is inserted into the insertion hole 46 of the moving plate 34. To the engaged state, and at the same time, the arm plate 40 is erected to move the moving plate 34 upward, and the waste storage box 32 also moves upward.
The upper edge of the upper end is sunk into the lower surface of the base plate 14 so that the shredded waste D does not scatter from the waste storage box 32 to the outside.

The waste container box 32 is filled with shredded waste D,
When the door 12d is opened, the moving plate 34 moves outward together with the hook means 48 and the insertion hole 46 in the engaged state, but with the arm plate 40 falling forward, the moving plate 34 moves. 34 is displaced downwards and the hook means 48
Is disengaged from the insertion hole 46 and the engaged state is released.
As a result, the door 12d is completely opened, the waste container box 32 is also moved downward, the state in which it is in contact with the base plate 14 is released, and the waste container box 32 can be taken out.

After discarding the shredded waste D in the waste storage box 32, the storage box 32 is placed on the moving plate 34 again, and the door 1
When 2d is closed, the front end of the moving plate 34 is pressed by the inner end surface of the door 12d, and at the same time, the arm plate 40
And the moving plate 34 is displaced upward, and the insertion hole 46
The tip of the hook means 48 is inserted into. At the same time, as described above, the waste storage box 32 again moves upward, and its upper end edge contacts the lower surface of the base plate 14. Shredding work is possible in this state.

In the above-mentioned embodiment, the fan mechanism 50 as the scrap leveling means has been described as an example in which the fan mechanism 50 does not move up and down only by rotation, but it is desired to smooth the shreds of scraps even when the shreds are small. The fan mechanism 50 can be configured to be movable up and down depending on circumstances.

Although the rotation speed of the fan mechanism 50 is not described in particular, it does not blow air like an ordinary fan, so that it is sufficient to rotate the fan mechanism 50 at a slow speed. Is achieved.
