BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a splitter according to the present invention will be described with reference to the accompanying drawings.
[0008]
FIG. 1 is a side view of a splitter 10 according to the present invention, and a conveyor system for transporting the dough d divided and discharged from the splitter 10 to the next process. FIG. 2 is a side view of a main part of the splitter 10. FIG. 3 is a horizontal sectional view of the required part.
[0009]
The splitter 10 includes a hopper 14 for supplying the dough d, a wide and flat rectangular cross-section rectangular cylinder chamber 16 (FIG. 3) for receiving the dough d from the hopper 14, and a cylinder chamber 16 (in FIG. A main ram 18 slidably (in the left-right direction) and a plurality of main rams 18 (shown in the figure) that are arranged adjacent to one end opening (left end opening in the figure) of the cylinder chamber 16 and receive the fabric d from the cylinder chamber 16 The fabric dividing block 22 includes five (5) pockets 20 and a small ram 24 inserted from the left end opening of the pocket 20.
[0010]
The dough d is supplied from the hopper 14 into the cylinder chamber 16 and is filled in the pocket 20 of the dough dividing block 22 by driving the main ram 18 to the left. FIG. 3 shows a state in which the upper three pockets 20 are filled with the fabric d in FIG. When the dough d is filled, the dough dividing block 22 is moved to a predetermined position in the vertical direction, where the small ram 24 loaded in the pocket 20 is driven forward (by a driving device not shown) to the right. Then, the dough d is discharged onto the conveyor of the above-described conveyor system (FIG. 3 shows a state in which the two small rams 24 shown in the lower part of the figure are moved rightward and the dough d is discharged). . After discharging the dough d, the dough dividing block 22 is moved vertically upward to receive new dough d from the cylinder chamber 16. At this time, the small ram 24 in the pocket 20 is pushed by the dough d to be filled, is engaged with the stopper 26 provided corresponding to each small ram 24, and retreats until it stops. Therefore, the volume of the dough d to be filled in the pocket 20 is determined by the volume of the (dough filling) space formed between the small ram 24, which is retracted and stopped, and the dough receiving port 25 at one end of the pocket. You.
[0011]
As shown in FIG. 3, the stopper 26 is supported by a frame 30 extending in a horizontal transverse direction. The stopper 26 is moved toward and away from the small ram 24 by a mechanism as described below to adjust the relative position with respect to the small ram 24. Is adjusted.
That is, the frame 30 has a rod 32 extending at both ends thereof in a direction parallel to the moving direction of the small ram 24 in the pocket 20 (in the figure, in the left-right direction). The drive shaft 34 is engaged with a gear 34 ′ formed on a drive shaft 34 extending in a horizontal transverse direction, and is driven in the left-right direction with the rotation of the drive shaft 34. That is, the drive shaft 34 is drivingly connected at one end (the lower end in FIG. 3) to the drive motor 36, and is driven to rotate around the central axis of the drive shaft 34 by the motor 36. The rotation of the drive shaft 34 causes the rod 32 to move to the right or left, and the frame 30 connected thereto to move toward or away from the pocket 20. An encoder is mounted on the upper end of the drive shaft 34 as seen in FIG. 3, and the controller 48 of the splitter dictates the amount of rotation of the drive shaft 34, and thus the position of the stopper 26 moved by the drive shaft 34. Feedback. Proximity switches 38 and 40 that determine the movement limit of the rod 32 are attached to the vicinity of the tip of the rod 32 at the lower position in FIG.
[0012]
As shown in FIG. 1, the dough d discharged from the splitter 10 is advanced to the next step through a conveyor system. At a middle position of the conveyor system, a pair of weighing conveyors forming a part of the conveyor system is provided. An automatic weighing device 46 is provided, which is provided with 42 and 44 and automatically weighs the mass of the divided dough d that has been transported. This automatic weighing device can measure the dough for each pocket.
[0013]
In FIG. 1, reference numeral 48 indicates a controller of the splitter 10 according to the present invention.
The controller includes a calculating means 60, that is, a CPU (FIG. 4), and has a function of determining an appropriate setting position of the stopper 26 based on the weighed value measured by the automatic weighing device 46.
That is, the calculating means includes a specific gravity calculating means 62 for calculating a specific gravity of the weighed dough d, and a dough in the pocket 20 required to make the dough d discharged from the pocket 20 a target mass. It is necessary to set the volume of the dough filling space in the pocket 20 to the calculated volume based on the calculated volume and the volume calculating means 64 that calculates the volume of the filling space from the specific gravity of the dough d. And a retreat position calculating means 66 for calculating a retreat preventing position of the ram by the stopper 26.
The calculating means sends the number of pulses corresponding to the value calculated by the retreat position calculating means 66 to the drive motor 36, thereby causing the position of each stopper 26 to be adjusted.
In this case, since the dough d measured by the mass weighing device and the dough d newly split by the splitter 10 are different in a splitting condition factor such as a fermentation state, the point is taken into consideration. The pulse sent to the drive motor 36 can be a signal obtained by applying a predetermined correction value.
[0014]
The controller 48 also has data input means for inputting necessary data relating to the division work conditions, such as the cloth temperature when the division operation is performed and the dough d setting time, and the arithmetic means is operated by the data input means. Storage means 70 for storing the data to be obtained, the average value of the mass of the divided dough measured by the automatic mass weighing device 46, and the standard deviation value for the same mass from the value of the variation of each divided dough mass from the average value And a means 74 for specifying the relationship between the standard deviation value calculated by the means and the data.
Specifically, the standard deviation value calculation means 72 calculates the average value of the divided dough mass, squares the difference between the calculated average value and the mass value of each divided dough, and sums the sum to the number of divided doughs. Divided by 1 minus the number, and the square root is used as the standard deviation value. The input data can be input by an operator through a control panel of the controller, or can be automatically input by installing a required sensor or the like.

The calculating means calculates a difference between the maximum value and the minimum value of the masses of the predetermined number of divided doughs measured by the mass weighing device, that is, a means 82 for calculating the maximum difference. Are assumed to be naturally distributed, a predetermined count that is statistically determined to obtain the standard deviation value (for example, for a measured number of 10; 50; 100; 1000, each count is 0.325; 0.222; 0.199; 0.154) by multiplying the maximum difference by the above-mentioned maximum difference to calculate a standard deviation value, and the standard deviation value calculated by the means and the standard deviation value calculating means 72. And a comparing means 86 for comparing the standard deviation value calculated from the above.
According to this, when there is a certain difference or more between the two standard deviation values, it is possible to estimate that the mass of the divided dough is not in a natural distribution state, and that there is some abnormality. .
[0016]
Outputs of the specifying means 74 and the comparing means 86 are displayed on a monitor 76 of an operation panel of the controller, and necessary adjustment operations can be performed while watching the monitor.
