Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a document shredding device for shredding documents, etc. About

[Technical cost of invention and its problems]

A shredder is formed in the upper part of the casing main body, which has an inlet for inserting documents, etc., and is equipped with a shredding cutter for shredding the documents, etc. that are inserted from the input [-1]. A document shredding device is installed at the bottom lj position of the chamber with an upper-opening cylinder that receives the shredded debris that falls through the 1!1 exit of the shredding chamber and disposes of documents, etc. This is an auxiliary device that can be used as an auxiliary device, and is widely used in school offices and other places.

Conventionally, in a document shredding device with such a structure, GEL
When the cylinder is full, the operation is stopped based on a signal detected by the debris detection means installed inside the casing body, the cylinder is removed from the casing body, and the cylinder is removed from the casing body. A process to dispose of shredded waste is carried out.

The shredded waste shredded by the shredding cutter falls into the strata through the 11 outflows, but some of it remains in the shredding chamber or becomes shredded by static electricity generated during shredding. It often grows on the walls of the chamber. When taking out the cylinder from the casing body, some of the shredded waste 1i remaining in this shredding chamber falls into the gauging body after taking out the cylinder due to the impact, and falls into the casing body. It collects on the bottom. Then, the shredded waste that was on the bottom of the woosing body was
When I took out the I+1 box, it broke out of the casing body, and I had to clean the area frequently.

In addition, conventionally, a detection means for detecting when the cylinder is full of shredded waste is installed at one position of the cylinder, and when a part of the shredded waste exceeds the upper edge of the strata. Previously, a detection signal would be emitted when the cylinder was full of shredded waste, so when taking out the cylinder, there was not enough room in the cylinder to accommodate shredded waste, and the strong vibration caused it to be easily removed. There was a problem with the tube spilling into the surrounding area. Furthermore, he took out the same cylinder. Afterwards, the inside of the casing body may be cleaned, but at this time, there have been cases where someone accidentally put their hand into the shredding chamber and was injured by the shredding cutter.

[Purpose of the invention]

The present invention has been made with these six points in mind.It is an object of the present invention to provide a document shredding device that does not scatter shredded debris when taking out the shredded debris from the non-nosing main body. target

[1.Summary of the Invention] In the present invention, a shredding chamber in which a shredding cutter is disposed at the lower part is formed in the cooshing main body, and a cutter is disposed in the lower part of the shredding chamber, and the material is dropped through the outlet of the shredding chamber. This is a document shredding device in which a cylinder with an open opening is installed to receive the shredded waste.
It is characterized by the fact that it has an ivy plate.

According to the present invention, when taking out the shredded waste, the outlet 11 is closed by the shutter plate, and it is possible to prevent the shredded waste from falling from the shredding chamber and being scattered around.

In addition, the present invention provides that the tip of the tip of the Shitotsuta play 1 is movable in a rocking manner within the layer phase, and a detector is installed to detect that the tip is movable in a rocking manner. It has many characteristics.

According to the present invention, when the 8 boxes are full of shredded waste,
, l ll notes swing and move, and by detecting the position of this swing movement v1, it is possible to detect debris in the layer phase. According to this debris detection method, debris can be detected at a point in time when there is relatively melting within the layer phase, and it is possible to prevent the debris from falling out of the cylinder when taking out the debris. I can do it.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 are a side sectional view and a front sectional view showing an embodiment of a document shredding device according to the present invention. In the figure, the reference numeral 11 is a casing body that has an input port 12 at its upper end, and inside this casing body 11 there is a
- A shredding chamber 14 in which a shredding cutter 13 is disposed is formed on the right side.

At the lower part of the shredding chamber 14, there is provided a discharge port 15 through which the shredded waste P shredded by the shredding cutter 13 is discharged. A tube 16 is installed.

One side of the casing body 11 (in this example, the front side)
is an opening/closing door 11a whose upper end can be tilted toward the front with its lower end centered. 16 box 16 is this opening/closing door 1
It is attached to the inner -41 side of 1a using screws etc.
When the opening/closing door 11a is opened, the flap part of the waste box 16 comes out from the cushioning body 11.

Below the outlet 15 of the shredding chamber 14, a plate-shaped shutter brake 1, 21 opens and closes the outlet 15 around a swing shaft 22 pivotally attached to the bottom of the shredding chamber 14. J: Uo-do i) Noh is taken by HJ and C is.

In this embodiment 21, as shown in FIG. The vine 21a is for Jl Kusarikawa City 1, and the other narrow side is the balance surface 21b. A balance weight 23 that maintains balance and covers the end portion of this balance surface 21b (2, SI! Swing V of the ivy 21a) is fixed. Maruko, sil
The tip end 21c of the ivy 21a has a dimension larger than the distance between the swing shaft 22 and the upper end of the waste box 16, so that the tip 21c can swing in the same direction.

A V-shaped bent portion 24 is formed at one end of the swing shaft 22, and a permanent magnet 25 is attached to the tip of the extended shaft of this bent portion 24. V-shaped bent portion 24
The 0 part is similarly formed in a V shape, and is connected to the casing body 1.
The plate spring 26 fixed to the plate spring 1 is abutted and engaged with either surface of the leaf spring 26 with the top portion 26a in between. For example, Figure 1,
As is clear from FIG. 3, when the shutter 21a is listening, it abuts and engages with the upper surface of the leaf spring 26, and when it is closed, it abuts and engages with the lower surface of the leaf spring 26. ing. Also, at a position close to the permanent magnet 25, there is a glued switch 127 for detecting the swinging position of the V-shaped plate 21.
is installed.

On the opening edge of the outlet 15 on the side perpendicular to the shredding cutter 13, there is a spill-proof IL sheet [31] facing inside the same No. 16.
-C hanging down. This sheet]・31 is used to prevent the shredded waste from flying sideways due to static electricity and spilling out of the waste box 16 during shredding.For example, it is made of a synthetic resin sheet such as Poly L Stell. It is made. In this embodiment, an example in which the discharge outlet 115 is hung down only on the negative side of the opening edge is shown, but it is also possible to hang down on the entire periphery of the discharge opening 15.

In addition, in FIG. 2, C omitted t'> M1. L, the shredding cutter 13 is rotationally driven.

Next, the operation of this embodiment based on such a configuration will be explained.

FIG. 1 shows a state in which a document or the like is being shredded. The text 11 and the like input from the input port 12 are shredded by a shredding cutter 13 which is rotationally driven by a rotor M, and the shredded waste P falls downward through the discharge port 15. In this case, as shown in FIG. 1, in the scirett plate 21, the V-shaped bent portion 24 of the swing shaft 22 is placed on the upper surface side of the ■-shaped leaf spring 26 under the rotational force of the balance ways 1 to 23. The distal end portion 21c is stopped at a position where the distal end portion 21c is inclined at a predetermined angle.

Therefore, the shredded waste P that has passed through the outlet 15 falls into the shutter 21a-1-, further slides through the shutter 21a-1, and falls into the shutter 16.

In this way, when the shutter brake 1-21 is in the open state of the discharge hole 15, it is attached to the extended shaft end of the swing shaft 22.
The permanent magnet 25 keeps the reed switch 27 in the ON state, and the document shredding device continues to operate.

The amount of shredded waste P that has fallen into No. 16 has increased, and the upper end P
When o comes to a higher position than the tip 21G,,L of the shutter 21a, it becomes difficult for the shredded waste P to disappear from the shutter 21a, and gradually the tip 21C of the ivy 21a
It accumulates nearby. When the sum of the weight of the shredded waste P accumulated on the shutter 21a and the weight of the ivy 21a becomes greater than or equal to the sum of the weights of the balance way 1 and the balance surface 21b, the V ivy plate 21 In FIG. 1, it swings in the direction of the arrow (anti-l'\51 direction). Due to the swinging of this embodiment 21, the extension shaft end of the swinging shaft 22 is
The permanent magnet 25 also moves, and the reed switch 27 is turned to O.
Set to FF state. As a result, the operation of the document shredding device is stopped, and a signal indicating that the waste box 16 is -1 full is issued.

A method for removing the shredded waste P from the inside of the vehicle 16 and discarding the scrapped vehicle will be explained with reference to FIG. First in the closed position (
Condition in Figure 1) Place the upper end of the opening/closing door 11a on the front side (left side)
, and swing the lower end of the opening/closing Bi 11a as a fulcrum. When the opening/closing door 11a comes to position Y in Fig. 4, SI1? The tip 21 of the vine 21a (Cl;i, is pushed up by the upper back end 16a of the layer phase 16. Due to this pushing up action, the V-shaped bend formed on the extension shaft of the rocking shaft 22 of the scissetter plate 1-21 The portion 24 rides over the top portion 26a of the leaf spring 26 as the leaf spring 26 is elastically deformed, and moves to the lower surface of the leaf spring 26.The bent portion 24 moves over the top portion 26a of the leaf spring 26. 26a, the balance weight 23 moves the entire shutter brake 1-21 further in the direction (see Figures 1 and 4).
Rotate and SEE! The ivy 21a closes the discharge port 15.

The opening/closing door 11a is opened to the 7th position and held in the open position by an appropriate means, such as a chain (not shown) connecting the opening/closing door 1a and the casing body 11. . At the 7th position, the upper opening of the layer 16 is completely removed to the outside of the casing body 11, and the shredded waste P is extracted from the waste box 16 and discarded.

This shredded waste P can be removed at will by installing a collection bag (such as a plastic bag) in the waste box 16.

During this work of taking out and disposing of the shredded debris, the discharge port 15 is closed by the ivy 21a of the shredder 11, so that the shredded debris remaining in the shredding chamber 14 falls out.
When the layer phase 16 is taken out and the inside of the casing body 11 is cleaned, the shutter 21a When the discharge port 15 is closed, CS Ii inserts his hand into the shredding chamber 14 and removes the shredding cutter 1.
3 will not injure your hand.

After the disposal of the shredded waste is completed, an operation is performed to close the opening/closing door 11a. The opening/closing door 11a is swung from position 7.
When reaching the position @ (Fig. 4), the upper back end 1 of the facies 16
6a comes into contact with the balance surface 21b of the shutter plate 21, and when the opening/closing door 11a is further swung in the closing direction, the balance surface 21b is pushed by the upper back end 16a of the layer phase 16 and moves in the direction of the reaction bar 1. Being shaken and mouthed. Due to this swinging motion, the V-shaped bent portion 24 elastically deforms the leaf spring 26 and moves over the sacral portion 26a of the leaf spring 260) to the upper surface side of the leaf spring 26, and the small piece of the balance weight 23 causes the V-shaped bent portion 24 to move to the top surface of the leaf spring 26, and Abutting engagement is avoided on the side. To this J:
As mentioned above, the shutter plate 21

It can be detected by detecting the change in the swing position of 1, so it is not necessary to install a special detection device.
The structure of the lower part of the shredder '914 can be made into a cylinder. Roughly, this shredded waste is detected by swinging and moving the tip 21c of the shutter 21a that has entered the waste box 16, so that the shredded waste is detected up to the upper edge of the layer 16. It is detected before the debris accumulates, and the shredded debris can be taken out and discarded with some margin left above the layer phase 16. This makes it easy to take out the shredded waste and prevents some of it from spilling out of the layer 16.

FIGS. 5 to 8 are views showing other embodiments of the present invention.

This embodiment differs from the embodiment described above only in the shape of the shutter plate and the structure of the shutter plate, and since the rest is of the same construction, the same reference numerals are used. At the same time, we will omit the explanation.

In this example, one play 1~ shaped sheet 1 is used.

On the back side of the shutter brakes 1 to 41, there is a shield 1? formed in a substantially 1-shape. The vine retainer 43 has its - side 43a along the upper edge 141a of the shutter plate/11, and the other side 13b in a direction perpendicular to the edge 41a (
) are arranged. This scirette presser bar/I 3t
A spring 47 is connected to the end of the negative side 43a to pull the other side 43b to rotate in the direction of the shutter plate 41. has been done. The other side/the tip of Ib is
It is further bent while holding it in a direction perpendicular to the upper edge 'lla, and this bent portion comes into contact with the vicinity of the upper edge of the 16th member, and serves as the 16th contact portion 43G.

In this embodiment, during the shredding operation, the shutter blade t-/+1 is lowered as shown in FIG. is open. In this state, the switch operating lever 44 comes into contact with the detection switch 45, and the shredding operation is continued.

The shredded waste P falls from the shredding chamber 17I through the Tagawa [115] into the same No. 16, and the No. 16 is filled (when it comes to 7 pieces, the shredded waste P) ends Po to the shutter plate 41. The tip portion 41b is pushed and swings in the counterclockwise direction in FIG. , signals that the shredder day is full.

On the other hand, during this shredding operation, the shutter presser bar 43
During this period, the first contact portion 43G is brought into contact with the upper edge of the waste box 16 by the tensile force of the spring 47. During this time, due to the abutting action of the 1st abutting portion 43C, the 16th casing main body 1
It is fixedly held at a predetermined position within 1. J, T, No. 16 is attached to the opening/closing door 11a (St l-J is fixed, so

When the opening/closing door 11a reaches the 7th position and stops, press the 1st contact part 43G between 1 and 13.
is completely removed from the 16th part, and the spring 47 further releases the 1-
1st place VI. The back of the shutter plate 41 is pushed up by the l-r swing, and the shutter plate 41 is moved to Tagawa []
15 in the closed position.

This prevents the shredded waste remaining in the shredding chamber 1/l from falling from the discharge port 15 and scattering inside the casing body 11.

When closing the door 11a, the shutter plate 41 opens in conjunction with this.

First, when the opening/closing door 11ah is closed to the vicinity of the Y position, the 16th to-end deep part pushes the shutter presser bar 43 between the 1st abutting portions/13C, and the shutter presser is pressed against the tensile force of the spring 47. The rod 43 is swung in the i1 direction. When the opening/closing door 11a is closed almost to the closed position, the contact portion 43c of the shutter presser bar/I3 again contacts the upper edge of the sixteenth member, and is pressed upward by the tensile force of the spring 47. (l. Also, the shutter plate 41 swings together with the swinging of the shutter presser bar 43, and is suspended with its tip 41b entering the same 16th.
11, the detection switch 45 is activated.

According to this embodiment, the shutter plate 41 can have a more cylindrical structure than those of the previously described embodiments. In addition, since the discharge port 15 is completely opened,
During shredding, the shredded debris does not collide with the shutter plate 1-41, making it easy to adjust the debris detection position Ml. In addition, the tip of the shutter plate 41/Ilb is
I penetrate deeper than 6! Therefore, it is possible to detect debris at an earlier timing.

In addition, since the scissor presser bar 43 has the function of fixing the spacer 16 with the pusher 1 () when the door 11a is closed, a mechanism for closing the door 11a is specially designed as in the conventional case. Even without this, the closed state of the opening/closing door 11a can be maintained.

In addition, in the embodiment explained above, as an opening/closing door,
The opening/closing door is shown in No. 1, which has a mechanism that tilts M with its lower end as a fulcrum.
It may also be a door that opens and closes laterally. In addition, although we have shown an example in which the interstage is fixed to the opening/closing door (d' good.

Further, although an example is shown in which a reed switch and a microswitch are used as the debris detection switch, various other switches such as a photoelectric switch h may be used.

In addition, the timing of opening and closing of the shutter blaze is as follows:
The balance surface 21i) which contacts the upper end edge of the interlayer or the layer-corresponding contact portion 1n can be adjusted by changing the shape, etc. Further, the opening/closing operation of the shutter breaker 1- may not be linked to the second take-out operation, but may be linked to the opening/closing action of the door.

〔Effect of the invention〕

As described above, according to the present invention, since the shutter brake 1 is provided to open and close the discharge port of the shredding chamber, when the shredded waste is taken out and disposed of, there is no air inside the shredding chamber inside the shredding body. There is no scattering of remaining shredded waste. In addition, it is possible to prevent injury from accidentally inserting a hand into the shredding chamber while cleaning the inside of the casing body.

In addition, since the detection of shredded debris is performed by also using the shutter play 1~, and the tip of the shutter is inserted into the same hole, it can be detected at the right timing, and the shredded debris can be detected from the middle. When taking out the dimensions, it can be done with plenty of space between. This makes it possible to quickly and easily dispose of scrapped vehicles without scattering shredded debris around.
