A cutting blade wear determination device (31) of a sheet processing device includes a cutting controller (33), a cutting trace extractor (34), and a determiner (35). The cutting controller (33), instructs formation of a cutting surface in a sheet placed on a table. The cutting trace extractor (34) acquires an image captured by imaging a portion of the back surface of a sheet where formation of a cutting surface is instructed and extracts, from the image, a cutting trace that is a line at which the formed cutting surface intersects the sheet back surface. When an assumed line that is a line at which a cutting surface assumed to be formed in the sheet by the cutting blade intersects the sheet back surface does not coincide with the extracted cutting trace, the determiner (35) determines that the cutting blade instructed to form the cutting surface is worn.

Abrégé

A cutting blade wear determination device (31) for a sheet processing device comprises a cutting control unit (33), a cutting trace extraction unit (34), and a determination unit (35). The cutting control unit (33) actuates a lifting mechanism that can move the cutting blade in a direction orthogonal to a sheet placed on a table, and a horizontal movement mechanism that can move the cutting blade parallel to the surface of the table in a state in contact with the table, the cutting control unit commanding the formation of a cutting surface with the cutting blade on the sheet placed on the table. The cutting trace extraction unit (34) acquires an image by imaging, with a camera (21), the rear surface of the sheet at the section where formation of the cutting surface has been commanded, and extracts a cutting trace, which is a line where the formed cutting surface and the sheet rear surface intersect, from the image. The determination unit (35) determines that the cutting blade for which the formation of the cutting surface has been commanded is worn when an assumed line, which is the line where the cutting surface assumed to be formed on the sheet by the cutting blade intersects with the sheet rear surface, and the cutting trace extracted by the cutting trace extraction unit (34) do not match.

Abrégé

A sheet processing apparatus (1) includes a first processing section (1000), a second processing section (2000), and a third processing section (3000) arranged on a straight line, and conveys a sheet (4200) therebetween. The first processing section (1000) forms a plurality of first processing lines extending in a first direction (an X axial direction) on the sheet (4200), by moving a plurality of tools (1110-1260) to the first direction in relation to the sheet (4200). The second processing section (2000) forms a plurality of second processing lines to a second direction (a Y axial direction) orthogonal to the first direction on the sheet (4200), by moving a plurality of tools to the second direction in relation to the sheet (4200). The third processing section (3000) forms a third processing line (aslant line, curve line) on the sheet, by relatively moving the sheet (4200) and the tool (3110, 3120).

Abrégé

A sheet-cutting device (1) is provided with a first cutting unit (1000), a second cutting unit (2000), and a third cutting unit (3000), arranged in a straight line, a sheet (4200) being conveyed between the cutting units. The first cutting unit (1000) causes a plurality of tools (1110-1260) to move relatively in a first direction (X-axis direction) in relation to the sheet (4200), whereby a plurality of first cut lines extending in the first direction are formed in the sheet (4200). The second cutting unit (2000) causes a plurality of tools (2110-2260) to move relatively in a second direction (Y-axis direction) that is orthogonal to the first direction in relation to the sheet (4200), whereby a plurality of second cut lines extending in the second direction are formed in the sheet (4200). The third cutting unit (3000) causes the sheet (4200) and tools (3110, 3120) to move relative to each other, whereby third cut lines (diagonal lines, curved lines) are formed in the sheet.
