The feature of the present invention is that, by using a rotating waste leveling means, for example, a fan mechanism having a plurality of leveling blades, the shredded waste that has fallen into a waste storage box and has a heaped shape is removed. By uniformly distributing and smoothing the waste in the entire waste storage box, the volume of the shredded waste is reduced and the waste storage amount is increased. In the present invention, since the scrap leveling means is rotated at the upper part of the scrap storage box to flatten the mountain-shaped shredder, the mechanism is simplified as compared with the installation of the compression means. There are advantages.

[0010]

An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 12 denotes a shredder for shredding waste paper P and the like. The shredder 12
Is formed in a box-like body including a bottom plate 12a, a side plate 12b, and an upper lid plate 12c, and a door 12d is provided at the front part so as to be openable and closable. A base plate 14 is attached to a peripheral portion of the inside 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. The upper space 13 has a pair of vertical cutters 1.
There is provided a shredding portion 20 comprising 6, 16 and a transverse cutter 18 provided below the vertical cutter.

Reference numeral 22 denotes a motor for driving the shredding unit 20. The motor 22 is provided on a substrate 24. Reference numeral 26 denotes a dust-proof cover that covers the motor 22. Reference numeral 28 denotes a control box in which a control mechanism for controlling the driving of the shredder 12 is housed, and is also covered with a dustproof cover 30.

In the lower space 15 of the shredder 12, a waste storage box 32 is disposed on the bottom plate 12a via a movable plate 34 which can be moved up and down. Reference numeral 33 denotes a scattering prevention frame which is attached so as to cover the entire periphery of the lower surface of the base plate 14 and acts so as to prevent the shredder D from scattering and dropping from the dust storage box 32.

2 and 3, reference numeral 36 denotes a bearing plate provided on a side edge of the bottom plate 12a. 38 is
It is an auxiliary plate provided on a 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 denotes an insertion hole formed in the front end of the moving plate 34. Reference numeral 48 denotes an inverted J-shaped hook means attached to a side edge inside the door 12d.

In FIG. 1, reference numeral 50 denotes a fan mechanism provided with one or a plurality of blades 50a, and is a leveling means which functions to level shredder chips. 52 is the fan mechanism 5
A motor that rotates the motor 0 is mounted on a support plate 54 attached to the substrate 24. 56 and 58
Are a first dust sensor and a second sensor for detecting shredder chips. The first sensor is provided with the shredder D from the shredding section 20.
Is set at a position A (FIG. 7) where the particles fall and accumulate to form a mountain,
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
Although there is no particular limitation, four sheets are preferable. The shape of the blade 50a is not particularly limited as long as it has the function of smoothing the shredder chips, 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
A guard member (not shown) can be attached to the vehicle to prevent danger.

The operation of the above configuration will be described. Shreds D, such as waste paper, shredded by the shredder 20 of the shredder 12 fall and accumulate in a dust storage box installed below the shredder. The manner in which the above-mentioned waste leveling means, that is, the fan mechanism 50 is used is not uniform but may be variously used. For example, the fan mechanism 50 is also rotated at the same time as the shredding of the waste paper is started, and the fan mechanism 50 is stopped at the same time as the shredding is completed. In this case, the shreds shredded by the shredding unit 20 fall downward between the blades 50a of the fan mechanism 50 and are housed in the shredder storage box. This falling state is
As the blades 50a rotate, the blades 50a are uniformly dropped into the waste storage box.

Further, when a large amount of shreds reaches the position of the fan mechanism, the shreds are made uniform by the rotation of the blade 50a. When the second dust detection sensor 58 detects the shredder D, the dust storage box 32 is full of the shredder D, the shredding operation is stopped, and the dust storage box 32 is taken out. . It is preferable that after the cutting operation is stopped, the fan mechanism 50 is rotated for a short time to perform the last scraping operation.

As another mode of use of the fan mechanism, the first waste sensor 56 detects that the waste container box 32 is filled with the fine waste D and stops the shredding operation. Next, the fan mechanism 50 is rotated to perform a dust leveling operation. When the detection by the first dust sensor 56 disappears, the shredding operation is started. This operation is repeated, and the shredding operation is stopped when the second waste sensor 58 detects the waste. Thereafter, the waste storage box is taken out as described above. In this case, the shredding operation and the scraping operation can be performed simultaneously.

The waste storage box 32 is placed on a movable plate 34 located on the upper surface of the bottom plate 12a. When the door 12d is closed, the hook means 48 of the door 12d is inserted into the insertion hole 46 of the movable plate 34. When the arm plate 40 rises at the same time, the movable plate 34 is displaced upward, and the waste container 32 is also moved upward.
The upper edge of the chip is in contact with the lower surface of the base plate 14 so that the chips D are not scattered from the chip storage box 32 to the outside.

The waste storage box 32 is filled with shreds D,
When the door 12d is opened, the moving plate 34 moves outward together with the hooking means 48 and the insertion hole 46 in the engaged state, but the moving plate 34 falls forward with the movement of the moving plate 34. 34 is displaced downward 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 dust storage box 32 also moves downward, the state of contact with the base plate 14 is released, and the waste storage 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 movable plate 34 again, and the door 1
When the 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 is closed.
The movable plate 34 is displaced upward, and its insertion hole 46
The tip of the hook means 48 is inserted into the hook. At the same time, as described above, the waste storage box 32 moves upward again, and its upper end edge contacts the lower surface of the base plate 14. Shredding work is possible in this state.

In the above-described embodiment, an example has been described in which the fan mechanism 50 as the dust leveling means only rotates and does not move up and down. However, even when the amount of the fine dust is small, it is desirable to level the pile of the fine dust. For example, the fan mechanism 50 can be configured to be vertically movable.

Although the rotational speed of the fan mechanism 50 is not specifically described, it is not a fan that blows air like a normal fan. Is achieved.
