BACKGROUND OF THE INVENTION
The present invention relates to a method for cutting food dough, such as bread dough, and a food dough forming apparatus. More specifically, the present invention relates to cutting a chunk from a strip-shaped food dough, and thinly extending the chunk with an extending roll device, and then rolling it into a roll shape. The present invention relates to a method for cutting a chunk and a molding apparatus for the same so that the roll can be wound and formed without forming a cavity inside.

[Prior art]
2. Description of the Related Art Conventionally, food dough such as bread dough is formed into a continuous band shape, the band-shaped food dough is cut into chunks having a predetermined weight or length, and then rolled into a roll shape. (See Japanese Patent No. 2579826)
[0003]
[Problems to be solved by the invention]
As described above, when the strip-shaped food dough is cut into chunks of a predetermined weight, for example, when the chunks are rolled up as they are, the tip of the chunk is in a state of being cut in a straight line. However, after cutting into chunks of a predetermined weight, when the food dough is rolled up in a roll shape after passing between a plurality of spreading rollers, it is said that cavities are likely to occur in the rolled up product. There's a problem.
[0004]
That is, as shown in FIG. 1 and FIG. 2, the food dough 1 formed in a strip shape in advance is transported in one direction by a first transport device 3 such as a belt conveyor, and the first transport device 3 is appropriately positioned. Alternatively, the food dough 1 is appropriately weighted or appropriately lengthed by an appropriate cutting device 7 such as a guillotine type or a rotary cutter disposed between the second conveying device 5 on the downstream side and the first conveying device 3. The chunk 9 is cut and separated.
[0005]
Since the cutting blade 7B in the cutting device 7 is generally set in a direction orthogonal to the conveying direction of the food dough 1, the tip of the chunk 9 is in the conveying direction of the food dough 1. Is cut so as to form a straight line orthogonal to the.
[0006]
Thereafter, when the chunk 9 is conveyed to the extending roll device 11 in which a plurality of extending rollers are opposed to each other vertically, and thinly extended by the upper and lower extending rollers 11U and 11L in the extending roll device 11, the shape of the tip of the chunk 9 is As shown in FIG. 1, the central portion in the width direction of the chunk 9 becomes a concave portion 9 </ b> C. In other words, the leading end sides 9A and 9B on both sides in the width direction of the chunk 9 tend to protrude so as to precede the center portion in the width direction.
[0007]
That is, when the thick chunk 9 enters the narrow gap between the upper and lower extension rollers 11U and 11L, the leading edge of the chunk 9 is rolled and thinned. At this time, the center of the chunk 9 in the width direction is thinned. Although the food dough in the vicinity of the portion is restrained from surroundings and restricted in flow, both side portions in the width direction of the leading edge of the chunk 9 are open to the side, so that the flow is likely to occur as indicated by arrows. Is.
[0008]
Therefore, the vicinity of both sides tends to become faster and thinner than the vicinity of the central portion in the width direction of the front end edge of the chunk 9, and the head 9 enters earlier between the upper and lower extension rollers 11U and 11L. Therefore, if the chunk 9 is to be thinly extended by passing between the upper and lower extension rollers 11U, 11L, as described above, the center of the chunk 9 in the width direction is cut in spite of the fact that the leading edge is cut linearly. It is difficult to avoid the formation of the concave portion 9C in the portion.
[0009]
As described above, after the chunk 9 is thinly extended by the extending roll device 11, the chunk 9 is transferred to the downstream by the third transfer device 13, and the chunk 9 is rolled into a roll shape by a general known winding device 15 disposed on the downstream side. When winding, since the winding is started from the front end sides 9A and 9B on both sides of the chunk 9, a cavity 19 is generated inside the product 17 wound in a roll shape.
[0010]
Therefore, it is desired to prevent the generation of the cavity 19.
[0011]
[Means for Solving the Problems]
The present invention has been made in view of the conventional problems as described above, and the invention according to claim 1 is to cut a food dough formed into a strip shape into chunks of appropriate weight or length, and to extend the chunks to an extension roll device. When the food dough is cut into chunks when rolled up by a winding device after being spread thinly by the above method, the food dough cutting method is such that when the food dough is cut into chunks, the tip shape in the conveying direction of the chunks is cut into a protruding shape .
[0012]
The invention according to claim 2 is a cutting device for cutting a food dough formed into a strip shape into chunks of appropriate weight or length, an extending roll device for thinly extending the chunk, and a thinly extended food A food dough forming apparatus comprising a hoisting device for winding the dough into a roll shape, wherein the cutting blade in the cutting device cuts the food dough so that the tip shape in the conveying direction of the chunk has a protruding shape Shape.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, in order to describe the embodiment of the present invention in detail using FIG. 3, the food dough forming apparatus 21 according to the present embodiment is similar to the conventional configuration described with reference to FIGS. 1 and 2. First and second transport devices 3 and 5, a cutting device 7, an extension roll device 11, a third transport device 13 and a winding device 15 are provided. The food dough forming apparatus 21 is different from the conventional structure in the structure of the cutting blade 7B in the cutting apparatus 7.
[0014]
As understood from FIG. 3, the shape of the cutting blade 7B in the cutting device 7 is that when the chunk 9 is cut and separated from the food dough 1, the shape of the front end portion, that is, the front end portion in the conveying direction of the chunk 9 is It is the shape which cut | disconnects the food dough 1 so that the protrusion protruding in the direction may be exhibited. More specifically, when the food dough 1 is cut, the cutting portion (cutting edge) of the cutting blade 7B in the cutting device 7 is in the width direction near the center in the width direction of the leading edge (front edge) of the chunk 9. For example, it is formed in a V-shape or a curved projection shape (projection shape in the transport direction) or the like so as to have a V-shape, a curved projection shape, or the like preceding the both sides of the sheet. In FIG. 3, it is illustrated by a V-shape.
[0015]
In the above configuration, when the strip-shaped food dough 1 conveyed by the first conveying device 3 is cut and separated into chunks 9 having a predetermined weight or length by the cutting device 7, as shown in FIG. The shape is a shape exhibiting a protruding shape that protrudes in the conveying direction so that the vicinity of the center in the width direction precedes both sides.
[0016]
When the chunk 9 is conveyed to the spreading roll device 11 by the second conveying device 5 and the chunk 9 is to be thinly extended by the upper and lower extending rollers 11U and 11L, the vicinity of the protruding central portion 9P of the chunk 9 is 9P. First enters between the upper and lower extension rollers 11U, 11L and is thinly extended. Accordingly, the food dough in the vicinity of the center portion in the width direction of the front end edge of the chunk 9 can flow in the lateral direction, and is thinly extended from the vicinity of the center portion. A concave portion is not generated in the vicinity of the portion.
[0017]
Therefore, when the chunk 9 thinly extended by the third conveying device 13 is conveyed to the hoisting device 15 and rolled up in a roll shape, no cavity is generated in the roll-shaped product 17.
[0018]
By the way, although the cutting device 7 is illustrated in a guillotine type in which the cutting blade 7B moves up and down, the cutting device 7 is not limited to the guillotine type, and a rotary having a cutting blade on the outer peripheral surface of the rotating body. It can also be a cutter.
[0019]
【The invention's effect】
As will be understood from the above description, according to the present invention, when the food dough is cut and the chunk is separated, the front end edge of the chunk is protruded so that the vicinity of the center in the width direction precedes both sides. When the chunk is thinly extended by the extension roll device, since the extension starts from the protruding portion at the center portion in the width direction of the chunk, a recess or the like is generated near the center portion in the width direction. There is nothing, and the conventional problems as described above can be solved.
