Abstract

To provide a technique by which, in cutting apparatus and a method for cutting into a small block such as a paper money or a postcard out of a large sheet, the cutting accuracy of a manufactured small block can be improved, and steps can be simplified and cutting equipment can have a smaller size simultaneously. A cutting apparatus comprises: a first pusher for pushing and conveying the left side of the cut large sheet block, of which two adjacent reference sides that have been jogged as an upper side and a left side are placed on the cutting apparatus, toward the right side direction; a second cutting means for cutting the right side of the large sheet block pushed and conveyed by the first pusher and sequentially cutting the right end of the large sheet block while interacting with the pushing conveyance by the first pusher to divide the sheet into long column unit blocks in the up-and-down direction; a right side removal means for removing the remaining portion after the right side cutting by the second cutting means; a column unit block conveyance means for conveying the column unit blocks in the right side direction while maintaining a predetermined interval thereamong; a second pusher for pushing and conveying the upper sides of the cut column unit blocks toward the lower side direction; a fourth cutting means for cutting the lower side of the column unit block pushed and conveyed by the second pusher and sequentially cutting the lower end of the column unit block into small blocks while interacting with the pushing conveyance by the second pusher; and a lower side removal means for removing the remaining portion after the lower side cutting by the fourth cutting means.

a second cutting means for cutting the right side of the large sheet block pushed and conveyed by the first pusher and sequentially cutting the right end of the large sheet block while interacting with the pushing and conveyance by the first pusher to divide the block into long column unit blocks in the up-and-down direction;

a right side removal means for removing the remaining portion after the right side cutting by the second cutting means,

a column unit block conveyance means for conveying the column unit blocks in the right side direction while maintaining a predetermined interval thereamong;

a third cutting means for cutting each upper side of the column unit block;

a second pusher for pushing and conveying the upper sides of the cut column unit blocks in the lower side direction;

a fourth cutting means for cutting the lower side of the column unit block pushed and conveyed by the second pusher and that sequentially cuts the lower end of the column unit block while interacting with the pushing and conveyance by the second pusher to divide the block into small blocks; and

a lower side removal means for removing the remaining portion after the lower side cutting by the fourth cutting means.

2. The cutting apparatus according to claim 1, wherein the second cutting means cuts the left side of a final column unit block sequentially cut out of the large sheet block and comprises a left side removal means for removing a remaining portion after the left side cutting.

3. The cutting apparatus according to claim 1, wherein the second cutting means cuts the left side of a final column unit block sequentially cut out of the large sheet block and comprises a left side removal means for removing a remaining portion after the left side cutting.

5. The cutting apparatus according to claim 1,

wherein the first cutting means and the second cutting means use a single edge-shaped blade edge of which one side is substantially vertical and the other side has an inclined blade ridge,

the blade edge of the first cutting means is placed so that the left side of a cut large sheet block faces the substantially vertical side, and

the blade edge of the second cutting means is placed so that the left side of a cut column unit block faces the blade ridge.

6. The cutting apparatus according to claim 1,

wherein the third cutting means uses a single edge-shaped blade edge of which one side is substantially vertical and the other side has an inclined blade ridge, and

the blade edge of the third cutting means is placed so that the upper side of a cut column unit block faces the substantially vertical side.

7. The cutting apparatus according to claim 1,

wherein at least one of the first pusher or the second pusher includes a main pusher performing the pushing and conveyance from a feed start position to a midway position and a following pusher taking over the operation at a midway position from the main pusher to push and convey the same side and is placed so that one pusher returns to a feed start position while the other pusher is performing an intermittent feeding so as to be able to immediately start the next intermittent feeding.

8. The cutting apparatus according to claim 1, including:

a small block conveyance means for conveying the small blocks divided by the fourth cutting means in the right side direction while maintaining a predetermined interval thereamong; and

a strapping means for strapping the respective small blocks.

10. The cutting apparatus according to claim 1, wherein the right side removal means includes a butterfly mechanism that releases, immediately behind in the conveyance direction of the second cutting means, the remaining portion after the right side cutting in the upper or lower direction only when the remaining portion is dropped and that is normally horizontally closed, providing a configuration to control the opening and closing in accordance with the pushing and conveyance by the first pusher.

11. The cutting apparatus according to claim 1, wherein the lower side removal means includes a butterfly mechanism that releases, immediately behind in the conveyance direction of the fourth cutting means, the remaining portion after the lower side cutting in the upper or lower direction only when the remaining portion is dropped and that is normally horizontally closed, providing a configuration to control the opening and closing in accordance with the pushing and conveyance by the second pusher.

12. The cutting apparatus according to claim 1, wherein the right side and the right end, and the left side and the left end are mutually exchanged to provide a symmetrical configuration.

13. A cutting method by which a large sheet block obtained by stacking a plurality of large sheets is cut by a cutting means to divide the sheet into small blocks,

wherein the respective sides when the large sheet is seen from above are assumed as an upper side, a right side, a lower side, and a left side, respectively, and two adjacent reference sides that have been jogged are assumed as an upper side and a left side and are placed in the cutting apparatus, and

the method has the following steps:

a first cutting step of cutting the left side of the large sheet block so that a direction parallel to the left side conforms to the paper grain direction;
