Description

[Detailed description of the invention] (Field of industrial application) This is an invention of a document cutting machine that cuts the seal of an envelope containing a document and accurately shreds the read document vertically and horizontally.

(Prior art) The conventional document cutting machine of this type was Utility Model No. 57-25743.
As shown in the publication, the part that cuts the seal of the envelope and the insertion slot for documents that are to be shredded vertically and horizontally are located on different sides, such as the top and front of the machine box that houses the cutting machine. Moreover, since the pair of cutting blades that cut the document into strips in the vertical direction are opposed to the rotary blade that shreds the strip in the horizontal direction, the rotary blade that shreds the document in the horizontal direction cuts one of the strips. The disadvantage was that it was not possible to precisely shred the entire strip that flowed out from the cutting blade that cut the strip in the longitudinal direction.

(Problems to be solved by the invention) This invention has a part for cutting the envelope seal and an insertion slot for documents to be shredded vertically and horizontally on the front of the machine box, and also The strip is cut into strips, and then the cut strips are shredded in the transverse direction.

(Means for Solving the Problems) The present invention will be explained below using drawing symbols for easy understanding.

A document insertion slot 2 is provided at the upper front of the machine case 1, and a long groove 3 is formed in the horizontal direction at the lower front. The cutting edges are overlapped and placed opposite each other.

Vertical cutting blades 5 are arranged vertically in the machine box 1 facing the document insertion slot 2, and horizontal cutting blades 8 are arranged horizontally below the discharge port of the receiving funnel 7 looking behind it.

Then, a receiving box 10 for small pieces is freely inserted into and removed from the machine box 1 below the horizontal cutting blade.

(Function) In the present invention, when one end of an envelope containing a document is inserted into the horizontal long groove 3 at the lower front of the machine box 1 and moved along the long groove 3, the machine box 1 extending into the long groove 3 is vertically constructed. Since the cutting edges formed on the circumference of the rotary blades 4, 4 are rotated and overlapped to face each other, one end of the envelope is cut in a correct straight line, and the document inside can be removed.

When the document that has been read is inserted into the machine box from the document insertion slot 2 at the upper front of the machine case 1, the document is cut into a large number of vertical strips by vertical cutting blades 5 that rotate vertically in parallel. It falls into funnel 7.

Then, from the discharge port of the receiving funnel 7, each strip is cut into a large number of horizontally cut pieces by the horizontal cutting blades 8 that rotate in parallel on the left and right and falls into the receiving box 10, which are then taken out of the machine box and disposed of. do.

(Embodiment) To explain the present invention with reference to the embodiment shown in the drawings, reference numeral 1 denotes a machine box, in which a document insertion slot 2 is provided at the upper front, and a long groove 3 is formed in the horizontal direction at the lower front. Inside, the cutting edges formed on the circumferences of the rotary blades 4, 4 installed above and below are placed overlappingly and facing each other.

Reference numeral 5 denotes vertical cutting blades arranged vertically in parallel within the machine box 1 facing the document insertion slot 2, and 6 indicates the mounting axis thereof.

A receiving funnel 7 is installed in the machine box 1, looking behind the vertical cutting blades 5, 5 arranged vertically in parallel, and below the discharge port of the receiving funnel 7 is a mounting shaft 9 on which the horizontal cutting blades 8 are arranged in parallel on the left and right.
is constructed, and a receiving box 10 for small pieces is inserted below it so that it can be freely inserted and removed from below the long groove 3 in the front of the machine box 1.

As shown in FIG. 4, each pair of blades 4, 5, and 8 are moved in gears in opposite directions by a motor M in the machine box 1 to feed out the envelope or document while cutting it.

(Effect of the invention) In this way, according to the invention, one end of the envelope is moved along the long groove on the front of the machine box to break the seal, and the finished document is inserted into the machine box from the document insertion slot 2 on the front of the machine box. Therefore, not only is the machine box easy to use, but the strips produced by the vertical cutting blade 5 are accommodated in the receiving funnel 7 and sent to the horizontal cutting blade 8, so that the strips produced by the vertical cutting blade are not removed as in the conventional case. This results in the effect that the horizontal cutting blade accurately shreds all of the strips produced by the vertical cutting blade without the risk of the horizontal cutting blade tearing off part of the strip.
