Description

Shredder with automatic feeder.

The present invention relates to a shredder for finely cutting documents to be discarded, and more particularly, to a shredder equipped with an automatic paper feeder capable of minimizing time loss due to the sedan by adding an automatic paper feed function.

In general, a shredder is used to remove documents to be discarded. In the conventional shredder, when a user manually pushes a document into the inlet of the shredder one by one, the shredder is cut by a saw blade installed inside the shredder. .

However, there is no problem when the amount of documents to be discarded is small, but when there are dozens of documents to be discarded, it causes inconvenience to the consumer because the user has to manually push the documents one by one into the inlet of the shredder. In the case of documents that are regularly generated during the period, consumers have to destroy them manually, so that users cannot perform other tasks during the sedan work, and the work efficiency decreases due to the increased loss time required for the sedan. .

In order to solve the above problems, an object of the present invention is to provide a shredder equipped with an automatic paper feeder capable of discarding a large amount of documents in a short time.

Another object of the present invention is to provide a shredder equipped with an automatic paper feeder that can significantly reduce the time loss due to the shredding of documents to be discarded.

It is another object of the present invention to provide a shredder equipped with an automatic paper feeder that does not require the user to manually shred out documents to be discarded.

In order to achieve the above object, the present invention provides a shredder having an inlet into which documents to be discarded are injected, a sedan saw blade for finely cutting documents introduced through the inlet, and a scrap box for collecting pieces of documents cut by the sedan saw blade. In the present invention, the shredder is composed of an automatic paper feed cassette for stacking a plurality of documents, and an automatic paper feed roller installed at an upper portion of the automatic paper feed cassette to separate the documents one by one and feed them to the sedan saw blade side. Features automatic document shredding.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used for the same components, even if displayed on different drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a schematic view showing the configuration of a shredder equipped with an automatic sheet feeder according to a preferred embodiment of the present invention, Figure 2 is an automatic sheet feeder capable of automatically cutting the document in the shredder according to a preferred embodiment of the present invention It is a side view which shows the structure of an apparatus.

As shown in Figure 1 and 2, one side of the upper surface of the shredder is formed inclined at a predetermined angle in the inlet 12 opened in the upper direction in order to manually cut the document 26 to be discarded. One end in the inward direction of the inlet 12 is interlocked with the sedan saw blade 14 to finely cut the document 26 introduced through the inlet 12. And one side of the cutting saw blade 14 is provided with an automatic paper feed cassette 18 for loading a plurality of documents 26 to be discarded. At this time, the pedestal 30 is installed inside the automatic feeding cassette 18, and the document 26 is sequentially seated. On one lower surface of the pedestal 30, the uppermost portion of the automatic feeding cassette 18 is installed. A spring 28 pressurized with a predetermined elastic force is provided so that the document 26 loaded on the surface and the feed rake 22a of the automatic paper feed roller 22 are always in contact with each other.

In addition, on the upper side of the upper sheet of the automatic sheet feeder 18, the document sensor 20 for detecting the presence or absence of the document 26 to drive the automatic sheet feeder 22 and the sedan saw blade 14 Is installed. And on the other side of the upper side of the automatic sheet feeding cassette 18, that is, on one side of the sedan saw blade 14, the document 26 loaded in the cassette for feeding automatic sheet 18 is separated by a single saw blade sequentially ( 14) The automatic paper feed roller 22 is provided with a plurality of feed rakes 22a for feeding to the side. At this time, the feed rake 22a is formed on the automatic feed roller 22 to be inclined at a predetermined angle in the opposite direction in which the saw blade 14 is installed.

According to the configuration as described above, when the document 26 to be discarded by hand is first manually pushed into the inlet 12 of the shredder, the document 26 is interposed between the saw blades 14. Inflow. Subsequently, the document 26 is chopped by the rotation of the saw blade 14 and moves along the guide portion 16 to be accumulated in the waste box 32. That is, as shown in Fig. 1, the document 26 is disposed in the direction indicated by the dotted arrow (----) while being discarded.

Secondly, in order to shred a large amount of documents 26, first, a plurality of documents 26 to be discarded are stacked on the pedestal 30 of the automatic paper feed cassette 18. At this time, the document 26 is in contact with the feed rake 22a of the automatic paper feed roller 22 by a constant elastic force of the spring (28). Subsequently, the sensor 20 detects the document 26 loaded in the cassette 18 for automatic feeding, and drives the automatic paper feeding roller 22 and the sedan saw blade 14, whereby the automatic paper feeding roller 22 Rotate counterclockwise. At the same time, the feed rake 22a of the automatic paper feed roller separates the document 26 sheet by sheet and feeds it to the side of the saw blade 14, and the saw blade 14 cuts the document 26 finely. Afterwards, the finely chopped pieces are moved along the guide part 16 and stacked in the waste bin 32. That is, as shown in Fig. 1, the document 26 is disposed in the direction of arrow (?) While being discarded. Thereafter, as the above operation is repeated repeatedly, the document 26 loaded in the automatic paper feed cassette 18 is disposed of in a short time. At this time, the document that can be destroyed at one time is usually about 250 to 500 sheets.

As described above, the shredder equipped with the automatic paper feeder according to the embodiment of the present invention not only eliminates inconvenience for the user, but also improves the reliability of the product because the user does not need to separate the documents for manual disposal. In addition, by automatically cutting a large amount of documents can significantly reduce the work time, and also has the effect of improving the work efficiency.
