Abstract

A sampling apparatus is provided, which includes a pressing-up unit configured to press up a sheet piece that is being conveyed by a conveying unit, from a lower side of a conveyance course of the sheet piece to above the conveyance course; and
a holding unit configured to hold the sheet piece pressed up by the pressing-up unit.

First claim

The invention claimed is:

1. A sampling apparatus comprising:
a pressing-up unit configured to press up a sheet piece that is being conveyed by a conveying unit, from below a conveyance course of the sheet piece to above the conveyance course;
a holding unit configured to hold the sheet piece pressed up by the pressing-up unit; and
a separating unit configured to increase a distance between the sheet product and the sheet piece cut from the sheet product or a distance between sheet pieces cut from the sheet product.

2. The sampling apparatus according to claim 1 , further comprising:
a cutting unit configured to cut the sheet piece from a sheet product; and
an upstream-side conveying unit configured to convey the sheet product and send the sheet product to the cutting unit, wherein
the conveying unit is on a downstream side of the cutting unit along a conveyance direction of the sheet piece.

3. The sampling apparatus according to claim 2 , further comprising:
a speed adjusting unit configured to adjust a speed at which the conveying unit is conveying the sheet piece at a zone that includes at least a part of a segment of the conveying unit on an upstream side of the pressing-up unit along the conveyance direction of the sheet piece.

4. The sampling apparatus according to claim 1 , wherein
the conveying unit comprises a roller conveyer.

5. The sampling apparatus according to claim 4 , wherein
the pressing-up unit includes
a plurality of rod members, and
a rod member moving unit configured to move the rod members, wherein
the rod member moving unit is configured to move the rod members between below the conveyance course and above the conveyance course, and
for a case where the rod members are below the conveyance course, the rod members extend parallel to rollers of the roller conveyer and extend between the rollers.

6. The sampling apparatus according to claim 5 , wherein
a rod member at an upstream side along a conveyance direction of the sheet piece from among the rod members is a round bar.

7. A sheet member manufacturing apparatus comprising the sampling apparatus according to claim 1 .

8. A gypsum building material manufacturing apparatus comprising
the sampling apparatus according to claim 1 .

9. The sampling apparatus according to claim 1 , further comprising:
a speed adjusting unit configured to adjust a speed at which the conveying unit is conveying the sheet piece at a zone that includes at least a part of a segment of the conveying unit on an upstream side of the pressing-up unit along the conveyance direction of the sheet piece.
