BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described based on examples with reference to the drawings. FIG. 1 is a sectional view showing the structure of the embodiment, and FIG. 1 is a front view of a partial cross section of the split discharge device. That is, the hopper 1 for accommodating the bread dough W is provided supported by the frame 2. Hopper 1
A dividing cutter device 3 for cutting and dividing the bread dough W is provided at the bottom opening position of the. A belt conveyor 4 is provided below the split cutter device 3. A weighing roller 5 that is connected to the belt conveyor 4 to measure the weight of the bread dough and a cutting device 6 are provided downstream of the weighing roller 5 (FIG. 3). Downstream of the cutting device 6, various molding device groups 7 are provided.

In the embodiment, the bread dough W in the elongated hopper 1 is cut into a predetermined shape by the dividing cutter device 3, dropped on the conveyor 4 as the elongated chunk-shaped dough W1, and is placed downstream. Be transported. On the conveyor 4, these divided bread doughs W1 are respectively connected to the chunk-shaped dough W1 previously divided and cut, and the chunk-shaped dough W1 divided and cut thereafter, and continuously conveyed downstream. It Then, the conveyed continuous bread dough W2 is measured by the weighing roller 5, and the cutting device 6 obtains the bread dough W3 having a predetermined weight.
Further, the bread dough W3 is formed into a molding device 7 if necessary.
Various moldings are performed by.

A pair of rotating shafts 31 are rotatably provided near the bottom opening position of the hopper 1, and a plurality of blades 32 are attached to each rotating shaft 31. In this embodiment, the blade 32 has a configuration in which the base end portion of the first blade 32 is in contact with the adjacent second blade 32.
By providing the locations, the rotary shaft 31 is surrounded by the three blades, and is configured to rotate inward in synchronization with each other. The rotary shaft 31 has a hexagonal shape in this embodiment, and the blade 32 is fastened to the flat surface by screws.

As shown in FIG. 1, the tip portion 33 of the blade 32 has an inclined surface portion on the back side in the rotational direction.
As shown in FIG. 4, when the pair of rotating shafts 31 synchronously rotate the blades 32 and the blade tips 33 come into contact with each other, the sloped portions form a concave portion 34. The cutter device 3 is provided with a cutter motor 35 so that the blade 32 rotates in synchronization with the pair of rotating shafts 31. Further, the cutter motor 35 is provided with a control means 36 to control the motor 35. Also,
The synchronous rotation means of the rotary shaft 31 can be performed by a known means, for example, a mechanism including a plurality of gears.
(See JP-A-9-220048)

Regarding the rotation control of the rotary shaft 31, the rotation of the blade 32 performs the following operations. That is, the blade 32 is rotated by rotating the pair of rotary shafts 31 by 120 degrees in a state where the tip portions 33 of the first blades 32 are in contact with each other to seal the bottom portion of the hopper 1.
Rotation direction (arrow direction) so that the second blade abuts
Rotate to. Next, the rotating shaft is further rotated in the rotating direction of the arrow A (feeding direction) by a slight angle to separate the blade tip portion 33 (FIG. 4B), and then the rotating shaft is reversed to rotate the blade tip portion. The cutter motor 35 is controlled by the control means 36 so that the bottom portion of the hopper can be closed again by bringing 33 into contact with each other.

Next, the operation of this embodiment will be described. From the state where the bottom opening of the hopper 1 is closed by the split cutter device 3, the blade 32 bites into the bread dough W by the rotation of the rotary shaft 31. This blade 32
The blade tip portion 33 is inclined with respect to the radial direction (radial direction) of the rotation axis and oriented in the rotation direction, so that the bread dough W can be effectively sandwiched by the tip portion. Therefore, when the bread dough W is fed downward, slippage between the blade 32 and the bread dough W is prevented,
With the rotational movement of the blade 32, the blade 32 forcibly draws the bread dough W downward, and then the tip of the blade 32 can abut to cut the bread dough W, and the bread dough can be quantitatively cut and divided. You can The cut dough W1 is placed on the belt conveyor 4.

In this embodiment, the quantity of the dough to be divided and cut is determined by the volume V surrounded by the blade of the cutter device at the bottom opening of the hopper. Therefore, when the size of the dough to be cut and divided is desired to be changed. Is
It is possible to change the volume V by changing the thickness of the blade. It goes without saying that the blade can be attached and detached by using a screw other than the screw shown in the embodiment. When the bread dough W is cut, after the blade tip portions 33 contact each other by the control operation of the cutter motor 35, they are rotated by a slight angle so as to be further separated from each other, so that the dough is easily separated from the blade 32. .
In addition, at this time, when the blade tip portion 33 is provided with the depression 34, the depression (recess) becomes a non-adhesive portion with the cloth W in the hopper, and the result that the cloth W1 to be cut is easily separated can be seen. There is.

As described above, according to the embodiment of the present invention,
When the blade 32 has a shape surrounding the rotary shaft 31, the blade 32 can be easily oriented in the rotational direction with respect to the radial direction of the rotary shaft 31, and the bread dough can be reliably cut and discharged downward from the hopper bottom. it can. The blade uses a non-adhesive material made of plastic (for example, polypropylene, ultra high molecular weight polyethylene, etc.), and the base end of the first blade is brought into contact with the second blade so that the base of the second blade is When the end portion is brought into contact with the third blade, and similarly, the base end portion of the third blade is brought into contact with the first blade so as to surround the rotation shaft, the hopper bottom portion is formed only by the blade surface. It is hygienic and hygienic.

[0015]

As described above, according to the present invention, as a cutter device in a fixed amount dough discharging device for bread dough,
Attaching three or more blades to the rotating shaft with their tips inclined with respect to the radial direction of the rotating shaft so that they are oriented in the rotating shaft direction and control the rotation of the rotating shaft. Thus, the dough can be reliably sandwiched and quantitatively divided and cut. Further, in this case, in the three or more blades of the cutter device, the base end portion of the first blade is in contact with the adjacent second blade at three or more positions, and the rotary shaft is surrounded by each blade. By doing so, the hopper bottom formed by the blade surface becomes a smooth surface, so that the sticking of the bread dough can be reduced. Further, when the tip portions of the blades contact each other to form the bottom surface, by forming a recess at the position of the bottom surface side where the blade tip portions contact, it is possible to enhance the cutting action of the bread dough. It is possible. Further, by changing the blade, the division cutting amount of the bread dough can be easily changed.
