DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. FIG. 1 is a sectional view showing the configuration of the embodiment, and FIG. 1 is a front view of a partial section of the split discharge device. That is, the hopper 1 for storing the dough W is provided to be supported by the frame 2. At the bottom opening position of the hopper 1, a division cutter device 3 for cutting and dividing the bread dough W is provided. Below the split cutter device 3, a belt conveyor 4 is provided. A weighing roller 5 connected to the belt conveyor 4 for measuring the weight of the dough and a cutting device 6 provided downstream thereof (FIG. 3).
Downstream of the cutting device 6, various forming device groups 7 are provided.

In the embodiment of the present invention, the bread dough W in the elongated hopper 1 is cut into a predetermined shape by the split cutter device 3, and is dropped and mounted on the conveyor 4 as a slender chunk-like dough W1 to be downstream. Conveyed. On the conveyor 4, the divided bread dough W1 is connected to the chunk-shaped dough W1 that has been divided and cut before, and the chunk-shaped dough W1 that has been divided and cut thereafter, and is continuously conveyed downstream. You. Then, the conveyed continuous dough W2 is measured by the weighing roller 5, and a predetermined weight of the dough W3 is obtained by the cutting device 6.
Further, if necessary, the dough W3 is
Various types of molding are carried out by using this method.

Near the bottom opening position of the hopper 1, a pair of rotating shafts 31 are rotatably provided, and each rotating shaft 31 is provided with a plurality of blades 32, respectively. In the present embodiment, the blade 32 has three configurations in which the base end of the first blade 32 is in contact with the adjacent second blade 32, so that the rotating shaft 31 is formed by the three blades. They are enclosed and rotate inward in synchronization with each other. The rotating shaft 31 has a hexagonal shape in this embodiment, and a blade 32 is fastened to a flat surface of the rotating shaft 31 by a screw. The tip portion 33 of the blade 32 has a slope on the back side in the rotation direction as shown in FIG. 1, and a pair of rotating shafts 3 as shown in FIGS.
When the blade 1 rotates in synchronization with the blade 32 and the blade tips 33 come into contact with each other, a concave recess 34 is formed by the inclined surface. The cutter device 3 is provided with a cutter motor 35 so that the pair of rotating shafts 31
2 rotate synchronously. The cutter motor 35 is provided with control means 36, and the motor 3
5 is controlled. The means for synchronously rotating the rotating shaft 31 can be achieved by a known means, for example, a mechanism having a plurality of gears. (See Japanese Patent Application Laid-Open No. 9-220048)

Regarding the rotation control of the rotating shaft 31, the rotation of the blade 32 performs the following operation. That is, the rotation of the blade 32 is performed by rotating the pair of rotation shafts 31 by 120 degrees in a state where the tip portions 33 of the first blade 32 are in contact with each other and the bottom of the hopper 1 is closed.
Rotation direction (arrow direction) so that the second blade abuts
To rotate. Next, the rotating shaft is further rotated synchronously by a small angle in the rotation direction (feeding direction) of arrow A to separate the blade tip 33 (FIG. 4B). The control means 36 controls the cutter motor 35 so that the hopper 33 is brought into contact with the hopper 33 and the bottom of the hopper can be closed again.

Next, the operation of the present 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
Since the tip 33 of the blade is inclined with respect to the radial direction (radial direction) of the rotation axis and is directed in the rotation direction, the dough W can be effectively sandwiched between the tips. Therefore, in the operation in which the dough W is sent downward, the slip between the blade 32 and the dough W is prevented,
With the rotation of the blade 32, the blade 32 forcibly pulls the dough W downward, and then the tip of the blade 32 abuts to cut the dough W, thereby quantitatively cutting and dividing the dough. Can be. The cut bread dough W1 is placed on the belt conveyor 4.

In this embodiment, the size of the dough to be divided and cut is determined by the volume V surrounded by the blade of the cutter device at the opening at the bottom of the hopper, so that it is necessary to change the size of the dough to be cut and divided. Is
The volume V can be changed by changing the thickness of the blade. It goes without saying that the attachment and detachment of this blade can be carried out using screws other than those shown in the embodiments.

At the time of cutting the bread dough W, the blade tips 33 come into contact with each other by the control operation of the cutter motor 35, and then rotate by a slight angle so as to separate further, so that the dough is easily separated from the blade 32. Has become. In addition, at this time, if the dent portion 34 is provided in the blade tip portion 33, the dent (recess) is formed by the cloth W in the hopper.
The result shows that the cut cloth W1 is easily separated.

As described above, according to the embodiment of the present invention,
When the blade 32 has a shape surrounding the rotation shaft 31, the blade 32 can be easily directed in the rotation direction with respect to the radiation direction of the rotation shaft 31, and the dough can be reliably cut and discharged from the bottom of the hopper. it can.

The blade is made of plastic (for example,
Use a non-adhesive material such as polypropylene, ultra-high molecular weight polyethylene, etc., and bring the base end of the first blade into contact with the second blade, and connect the base end of the second blade to the third blade. If the base end of the third blade is brought into contact with the first blade so as to surround the rotation axis, the bottom of the hopper can be formed only by the blade surface, which is sanitary.

[0016]

As described above, the present invention relates to a dough fixed quantity discharge device for a dough, in which three or more blades are attached to a rotating shaft with their tips inclined with respect to the radial direction of the rotating shaft as a cutter device. By directing the dough in the direction of the rotation axis, the dough can be reliably sandwiched and cut quantitatively. Also, at this time, the three or more blades of the cutter device have three or more configurations in which the base end of the first blade is in contact with the adjacent second blade, and the rotating shaft is surrounded by each blade. As a result, the bottom of the hopper formed by the blade surface becomes a smooth surface, so that the adhesion of the dough can be reduced. Furthermore, when the tips of the blades come into contact with each other to form a bottom surface, by forming a concave portion at the position on the bottom surface where the blade tip contacts, it is possible to enhance the cutting action of the bread dough. It is. Furthermore, by changing the blade, the cut amount of the bread dough can be easily changed.
