Description

  The present invention relates to a bread slicing apparatus, and more particularly to a bread slicing apparatus for producing sandwich bread by cutting out so-called ear portions, which are edges of bread that has been sliced to a predetermined thickness in advance.

  2. Description of the Related Art Conventionally, a plurality of bread pieces obtained by cutting a so-called ear portion from bread and further slicing the bread pieces are sold as sandwich bread. Sandwich bread is manufactured using bread that has been baked in a rectangular parallelepiped shape. Generally, the manufacturing apparatus includes a band-shaped cutting blade for dropping an ear and a band-shaped cutting blade for slicing. When using the manufacturing apparatus, after a step of cutting each outer surface portion including the ear portion from a rectangular parallelepiped bread with a predetermined thickness, a step of slicing with a predetermined thickness in a direction intersecting the longitudinal direction is used. Bread is produced.

  By the way, the baked bread has a relatively hard outer surface, while the inside is soft, and each part becomes slightly harder as time passes after baking. Therefore, when slicing after the outer surface portion of the bread is first cut out as in the conventional manufacturing apparatus described above, the bread itself tends to be deformed only after a relatively long time has passed since baking. Difficult to do. Therefore, in the conventional manufacturing apparatus, since it takes a relatively long time from the baking of the bread to the manufacture of the sandwich bread, it is difficult to improve the freshness of the sandwich bread.

  On the other hand, when slicing bread first, it can be performed after a relatively short time after baking. However, since the sliced bread pieces are relatively soft, when the bread pieces are reciprocated to cut the bread pieces, the bread pieces are easily deformed, and the ear portions are appropriately excised from the bread pieces in a soft state. It is difficult.

  Therefore, the present invention has an object to provide a bread slicing apparatus capable of appropriately excising the ear portion from a piece of bread that is in a relatively soft state after a short period of time after being baked. And

  The present invention has been made in view of the circumstances as described above, and a bread cutting apparatus according to the present invention is mounted on a pedestal on which a bread piece obtained by slicing bread is placed, and on the pedestal. A fixing tool that presses and fixes the bread piece in a pressed state from above, and a disk cutter that cuts the bread piece fixed by the fixing tool.

  In such a configuration, even if the bread piece obtained by slicing the bread is relatively soft, it can be reliably fixed between the pedestal and the fixture, and the bread piece is relatively easy. Can be cut off. Moreover, since it cut | disconnects by the rotating disk cutter, compared with the case where it cut | disconnects by reciprocating a strip-shaped cutting blade, a bread piece is hard to deform | transform during cutting | disconnection and can cut a desired position appropriately. Moreover, a fine cut surface can be obtained, and the commercial value of the produced bread can be increased.

  In addition, the pedestal includes a transport unit capable of transporting the placed bread piece, and includes a moving unit that moves the fixing tool in a state where the bread piece transported by the transport unit is fixed. The disk cutter may be configured to cut a bread piece fixed by the fixing tool and conveyed by the conveyance unit along a conveyance direction of the bread piece.

  In the case of such a configuration, the bread pieces fixed by the fixture can be sequentially conveyed, and the conveyed bread pieces can be cut in a flowing manner. Therefore, many pieces of bread can be cut without human intervention, and it is possible to ensure freshness and improve work efficiency.

  Moreover, the said fixing tool may be comprised so that the at least edge part vicinity of the said bread piece may be press-fixed. Bread produced for sandwiches is generally cut off at the ears at the edges of the bread pieces. Therefore, in the case of the configuration as described above, when the ear portion is excised from the bread piece, the deformation of the bread piece can be prevented and the ear portion can be excised reliably.

  Further, the fixing tool is configured to press and fix the bread piece at a position near the cutting portion of the bread piece to be cut by the disk cutter and substantially opposed across the cutting portion. Also good. In the case of such a configuration, since the bread pieces are pressed and fixed on both sides sandwiching the portion to be cut, it is possible to further prevent the cut portions of the bread pieces from being deformed when cutting. Therefore, the desired position can be cut reliably.

  Moreover, you may provide the pin which is drawn into at least edge part vicinity of the bread piece of the state fixed with the said fixing tool, and supports this bread piece. In such a configuration, it is possible to prevent the bread piece fixed by the fixing tool from sliding or deforming between the base and the fixing tool, and it is possible to fix the bread piece more reliably.

  In addition, the pin is inserted into the bread piece in the vicinity of the cutting portion of the bread piece to be cut by the disk cutter and substantially opposed across the cutting portion, and supports the bread piece. It may be made as much as possible. In such a configuration, sliding and deformation of the cut portion of the bread piece can be prevented at the time of cutting, and a desired position can be cut reliably.

  According to the present invention, the bread piece on the pedestal is pressed and fixed by the fixing tool and cut by the disk cutter, so that the desired cutting portion can be reliably cut even with a relatively soft bread piece after baking. Can do.
