A sheet material processing apparatus, comprising:
- a conveyor;
- and
- a sheet material processing device, whereby the conveyor is configured for conveying a sheet material to be conveyed in a conveyance direction and then a predetermined processing is to be performed thereon by the sheet material processing device,
- wherein the conveyor and the sheet material processing device are provided in an apparatus body, the apparatus body including a side plate arranged at each side in a width direction,
- wherein the sheet material processing device comprises:
- an outer frame constructed from a top plate, right and left side plates, and a bottom frame;
- a first blade member including a first upper blade part and a first lower blade part each having a length extending in a first direction with respect to the conveyor and configured to press the both blade parts to each other so as to perform predetermined processing on the sheet material located between the both blade parts;
- a pressing mechanism for pressing the both blade parts to each other in a second direction perpendicular to the first direction;
- and
- a moving mechanism for moving the first upper blade part and/or the first lower blade part of the blade member relative to the apparatus body in the first direction with respect to the conveyor, wherein
- the first direction is the width direction perpendicular to the conveyance direction, wherein
- in one of the first upper blade part and the first lower blade part, a first processing blade for performing the predetermined processing is formed at one or more sites in the first direction, and wherein
- in the other one of the first upper blade part and the first lower blade part, a receiving part for the first processing blade or alternatively a second processing blade for performing the predetermined processing is formed at least over a section facing the first processing blade
- a support arranged between the side plates of the apparatus body, the support including a first slide receiving part and a second slide receiving part, each slide receiving part arranged in the width direction, the first upper blade part configured to slide in the width direction in the first slide receiving part and the first lower blade part configured to slide in the width direction in the second slide receiving part, the support configured to maintain a position relative to the side plates when the first upper blade part and first lower blade part slide in the respective slide receiving parts,
- wherein when the sheet material cut at a position deviated in the width direction from the correct position is conveyed by the conveyor, the moving mechanism is configured to arrange the first upper blade part and/or the first lower blade part at the correct position relative to the sheet material,
- wherein the blade member can move in the width direction within an inner space of the outer frame, and
- wherein the pressing mechanism and the moving mechanism are fixed to the outer frame.
