[0002]

2. Description of the Related Art A kneaded dough extruded by a spiral extruder is quantitatively divided by a cutter which is interlocked with a rotation of the spiral, and the extruder is also used. There is a technique of detecting a kneaded dough extruded from a sensor with a sensor and cutting it quantitatively by rotating the cutter, but in such a technique, since the extrusion density of the kneaded dough by the extruder is not constant, Even if the rotation interlock between the extrusion helix and the cutter is maintained constant, or even if the sensor that detects the extrusion position of the kneading dough works accurately, the density of the dough cut by the cutter changes a lot. , The weight is not constant. When handled by weight like tray packaging of food dough, even if the dough is cut and separated with a cutter, the weight must be measured for each kneaded food dough related to each tray packaging to determine the value. It requires trouble.

[0003]

The present invention is a kneaded dough A
And an extruding device 1 for extruding the dough A, and a weighing device 3 for weighing and weighing the extruded dough A while receiving it on a weighing conveyor 2.
And a cutter-4 for cutting the dough A sent out from the weighing conveyor 2 based on the weighing of the weighing device 3 having a constant weight.
And a kneading dough measuring cutter.

[0004]

The kneaded dough A extruded by the extruder 1 is received on the weighing conveyor 2 and weighed by the weighing device 3. When the weight of the dough on the weighing conveyor 2 is constantly weighed by the weighing device 3, the cutter-4 is operated to cut the dough while keeping the weigh of the dough constant.

The kneaded dough A thus extruded by the extrusion device 1 is weighed by the weighing device 3 while being extruded and transferred on the weighing conveyor 2, and the cutter 4 is operated by this weighing to operate the extruded dough A. Is cut into a constant weight, it is possible to improve the accuracy of constant weight of each cut dough A, and to perform the weighing of the dough A and the cutting of a constant weight while being extruded and transferred on the weighing conveyor 2. Therefore, continuous measurement and cutting processing can be performed by highly efficient extrusion transfer of the dough A.

According to the second aspect of the present invention, in the configuration in which the extrusion control device 5 is provided in the extrusion device 1, when the weight weighed by the weighing device 3 is larger than a certain set weight, the extrusion device 1
If the amount of extrusion by the extruder 1 is increased, the amount of extrusion by the extruder 1 is increased to control the amount of extrusion so that the weight of the extruded material A on the weighing conveyor 2 by the meter 3 becomes constant. Done.

With such a structure, even if the extrusion amount density of the extruded dough A by the extrusion device 1 changes, the extrusion control device 5 controls the extrusion amount of the dough A to adjust the density of the extruded dough A and the dough. The extrusion weighing of A and the cut weight can be maintained substantially constant, and a stable constant weight weighing and cutting process can be performed.

While measuring the weight of the dough A sent onto the weighing conveyor 2 by the weighing device 3 as in the invention of claim 3,
When the material A on the weighing conveyor 2 reaches a certain weight and is cut and separated by the cutter-4,
Since the dough A, which is weighed on the weighing conveyor 2, is directly cut and separated from the subsequent extruded dough A by the cutter-4, an error does not easily occur in the weighing, and more accurate constant weight cutting can be performed.

[0009]

1 and 2, an extruding device 1 for extruding a kneaded dough A, a weighing device 3 for receiving the extruded dough A on a weighing conveyor 2 and weighing the dough A, and the weighing conveyor. And a cutter-4 for cutting the dough A sent out from No. 2 on the basis of the constant weight of the weighing machine 3.
Further, an extrusion controller 5 is provided to control the amount of the kneaded dough A to be extruded in the extruder 1 by the metering device 3 so as to keep the cutting weight of the dough A by the cutter 4 constant.

In the extrusion device 1, an extrusion spiral 10 is provided at the bottom of a hopper 9 for accommodating the kneaded food dough A, which is rotated by electric power of the motor M1 to form a large number of extrusion nozzles 11 at the front end. It can be extruded while continuously forming like a noodle bundle.

A weighing machine 3 having a weighing conveyor 2 is provided with a kneading dough A extruded from the extrusion nozzle 11 and can be conveyed to the front side, and is constituted by a load cell. It is driven by a motor M2 on the upper side surface. The kneaded dough A is placed on the upper surface of the measuring belt 2.
While receiving and transporting, the weight is weighed by the weighing device 3 together with the weighing conveyor 2 and the like. A constant speed conveyor 12 driven by a motor M3 is provided on the lower side of the weighing conveyor 2, and the material A transported by the weighing conveyor 2 is directly transferred to the upper surface of the flat belt and transported.

A variable speed conveyor 13 is provided in front of the constant speed conveyor 12 and is electrically driven by a motor M4. A cutter 4 that is moved up and down by the expansion and contraction of the air cylinder 14 is provided between the constant speed conveyor 12 and the variable speed conveyor 13, and the fabric A inherited from the constant speed conveyor 12 onto the variable speed conveyor 13 is provided in the constant speed conveyor. It can be cut by the downward movement of the cutter 4 at the front end position of 12. The speed of the speed change conveyor 13 immediately after the cutting operation by the cutter-4 is automatically increased by the reference speed, so that the material A on the speed change conveyor 13 after cutting is promptly removed and the subsequent feeding operation is performed. The dough is weighed accurately. After the fast-forwarding of the dough is eliminated, it is automatically decelerated to return to the standard speed.

The tray conveyor 6 is provided for each of the cut fabrics A.
The trays T to be accommodated in each of them are placed side by side and fed out and conveyed, and are driven by an electric motor M5. A pulling plate 8 which is provided so as to convey the tray T close to the drop position of the material A sent out by the speed change conveyor 13 and which forms a receiving device 7 between the end of the speed change conveyor 13 and the tray conveyor 6. Also, an air cylinder 24 is provided. The pull-out plate 8 is made of a flat plate and is reciprocally provided so as to be parallel to the upper opening surface of each tray T on the tray conveyor 6 and parallel to the transport direction of the tray T. It is operated by the expansion and contraction of.
The cut material A is placed on the upper surface of the pulling plate 8 which is moving forward from the speed change conveyor 13 and is completely pulled out.
When the empty tray T is placed on the upper surface of the drawing plate and the empty tray T is located immediately below, the drawing plate 8 is rapidly pulled back to the rear by the air cylinder 24. Therefore, the material A on the drawing plate 8 upper surface falls in the same position due to position inertia. Then, it is accommodated in the tray T immediately below.

In such a structure, the extrusion spiral 1 is
The motor M1 of 0 has an inverter 15, and the motor M2 of the weighing conveyor 2, the motor M3 of the constant speed conveyor 12, the motor M4 of the variable speed conveyor 13 and the like have inverters. 16
Have. The PI controller 17 compares the measured output value of the load cell measuring device 3 with the target value of the frequency setting device 18, and feedback control is performed to the inverter 15.

By this, the extrusion amount of the dough A by the extrusion device 1 is controlled so as to be kept constant. For example, when the extrusion amount by the extrusion device 1 increases, the weighing conveyor 2
The weight of the upper fabric A is also increased, and the weight is increased by the measuring device 3,
The amount of electric output by the electric signal conversion by the load cell also increases, and as a result, in the PI controller 17, the deviation between the preset target value by the frequency setting device 18 and the detection value by the measuring device 3 increases. Output is made so as to reduce the control amount to the inverter 15 and the inverter 15
Is decreased, the rotation speed of the motor M1 is decreased, and the extrusion amount of the dough A by the extrusion spiral 10 is reduced to maintain and control the extrusion amount of a constant weight. Further, when the amount of the dough A extruded by the extruder 1 is excessively reduced and the amount of the dough on the measuring conveyor 2 is reduced, the opposite effect is obtained, and the rotation speed of the motor M1 is increased to increase the extruded amount. Then, the extrusion conveyance amount on the weighing conveyor 2 is controlled to be maintained at a constant weight.

The conveyors 2, 12 and 13 are drive motors.
The frequencies M2, M3, and M4 are adjusted and set by the frequency setter 19 so that the same peripheral speed is obtained. The rotary encoder 20 transmits a pulse corresponding to the rotation speed of the weighing conveyor 2 to the flow rate pulse generator 21. Reference numeral 22 is a weight integration counter, and 23 is a shift counter, which outputs a cutting timing signal to the cutter-4. As described above, when the weight A of the dough A on the weighing conveyor 2 increases, the amount of electricity in the weighing machine 3 also increases, and the rotary encoder 20 flows a pulse corresponding to the rotation speed of the weighing conveyor 2 as described above. Since the pulse is supplied to the pulse generator 21, when the number of pulses of the flow rate pulse generator 21 increases, the time until the counter of the weight integrating counter 22 goes up becomes shorter. On the contrary, when the weight of the dough A on the weighing conveyor 2 decreases, the time until the counter counts up similarly increases. The shift counter 23 outputs a cutting timing signal to the cutter-4 at the terminal end of the constant speed conveyor 12. The cutter-4 cuts the weight so that the weight becomes a constant amount by the cutting timing signal of the shift counter 23.

As described above, when the kneaded dough A is extruded from the extruding device 1, the extruded weight is conveyed on the weighing conveyor 2 and is constantly weighed by the weighing device 3. Cutter-4 under the weighing signal of constant weight
Since the dough A is cut for each constant weight, the weight of each cut dough A can be made uniform. Moreover, since the weight measurement is performed while the material A is being conveyed by the measurement conveyor 2, the weight cutting process is performed with high efficiency.

Further, in the extrusion device 1, the extrusion amount of the dough A from the extrusion nozzle 11 can be changed by controlling the rotation speed of the extrusion spiral 10 by the motor M1. Change control, measuring conveyor 2
The weight of the upper carrying material A can be maintained constant, and therefore the weight of the cutting material A cut by the cutter 4 can be maintained constant.

Therefore, as shown in FIG.
In the mode in which the long constant speed conveyor 12 is provided between the cutter 4 and the cutter-4, the measuring conveyor 2 to the constant speed conveyor 12 are provided.
This is effective because it is easy to keep the weight of the cut cloth A by the cutter-4 constant by keeping the conveyed weight constant throughout.

3 and 4 are different from the above example in that
The weighing conveyor 2 and the weighing device 3 are arranged on the rear side of the cutter 4, and the dough A conveyed by the extrusion device 1 and the constant speed conveyor 12 is weighed by the weighing device 3 while passing through the weighing conveyor 2, A constant weight is cut by the cutter 4 between the constant speed conveyor 12 and the weighing conveyor 2.

Therefore, since the dough A conveyed on the upper surface of the weighing conveyor 2 is weighed and directly separated from the succeeding dough A, a long conveying process does not occur between the weighing and the cutting, and during this conveying process. The change in weight of each cut dough A due to the change in the weight density of the dough A in Table 1 is small. Reference numeral 25 is a weight setting device for setting the weight of each cutting material A which is the measurement target value of the measuring device 3, and is composed of a frequency setting device.

In the same manner as in the previous example, the weight of the dough A conveyed on the weighing conveyor 2 is maintained constant by controlling the extrusion amount by the motor M1 of the extrusion device 1 by weighing the weighing device 3. It is also possible to control extrusion.

5 and 6, the difference from the above example is that
The weighing conveyor 2 and the weighing device 3 are provided in the middle of the tray conveyor 6, and the dough A conveyed by the constant speed conveyor 12 is directly received by the tray T on the weighing conveyor 2 and weighed, and the dough A received by the tray T is received. From the subsequent fabric A to the cutter
It is cut at 4. Therefore, the receiving device 7 as in the previous example is not necessary, and the configuration can be simplified. It should be noted that the conveyors 12, 2 and 6 are preferably set to have the same peripheral speed by the inverter 16.
