Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a method for weighing objects to be weighed supplied from a conveyance line using a plurality of weighing devices. The present invention relates to a control device for supplying objects to be weighed that controls the supply to an optimum level.

(Prior art) In food processing, for example, processing of potato chips, raw potatoes are fed to a slicer by a feeding device and sliced, and then fried in a fryer.
The workpieces, which are potato chips, are distributed to multiple conveyor lines. Next, on each conveyance line, the processed food is sprinkled with salt, seasoned with different flavors, etc. by supplying the specified weight J
In particular, every 14f1 is sent to a packaging machine for packaging processing.

(Problems with the prior art) In such a series of T processing, conventionally, the flow rate of the objects to be weighed on each conveyance line is visually checked, and the feeding speed of the feeding device and the feeding speed of the sorting device are determined by f-motion operation. It controlled the distribution ratio, the number of operating weighing devices, etc. For this reason, the supply amount of objects to be weighed is not sufficiently controlled, which may cause objects to be weighed to overflow from the conveyor line, or the number of operating weighing devices may not match the objects to be weighed fed from the conveyor line, resulting in long Reasonable metering control was not carried out, such as some equipment being operated idly for hours.

Furthermore, in the past, even if the amount of the object to be measured flowing through the conveyance line changed, the amount of salt or flavoring raw materials to be added to the object was not controlled, resulting in uneven flavoring.

(Objective of the Invention) An object of the present invention is to optimize the supply amount of the heavy material to be weighed in such processing and to control the seasoning of the heavy material to be weighed.

(R essential points of the invention) 1-In order to achieve the objects of the present invention as described above, the present invention:

When the weighing device weighs the object to be weighed brought in by the conveyance line, and the transportation condition of the heavy object to be weighed for each conveyance line, the acid of the object to be weighed supplied from each conveyance line to each weighing device is optimal. The object of the present invention is to provide an object to be weighed supply control device having an arithmetic and control device that controls the amount of objects to be weighed, and in item I, the distribution of objects to be weighed to each conveyance line is performed every time the amount is changed. The object of the present invention is to provide a control device for supplying objects to be weighed, which adjusts the amount of seasoning to the heavy objects to be weighed each time, thereby making the taste uniform.

(Example) Hereinafter, an example of the present invention will be described in detail using the drawings.

FIG. 1 is an overall view of the object to be weighed supply control device of the present invention. In the same figure, the feeding device 1 is constituted by a device 1b that conveys raw potatoes 1a by a conveyor or the like, as shown in an enlarged view in FIG. 2, and supplies the raw potatoes to a slicer 2. Potatoes, which are raw materials processed into a predetermined shape by the slicer 2, are fried by the fryer 3 to produce potato chips. As shown in the enlarged view in FIG. 3, the sorting device 4 supplies the chips to be processed at a predetermined distribution ratio to the lines FDA and FDB, which are a plurality of conveyor lines. Adjust the distribution to each line by moving in the directions of arrows (a) and (b).

The sorted potato chips are then sent to the salt sprinkler machine 5.
a, 5b, metal detector 6a, 6b, flavoring machine 7a, 7b
, and predetermined processing is performed respectively. Flavoring machine 7a, 7
The potato chips that have passed through b and have been seasoned differently are carried into conveyance line A and conveyance line B. Each of the transmission lines A and H has a plurality of shutters 91.
-912 are provided, and in detail, the conveyance line B is provided with shutters 91-95, and the conveyance line A is provided with shutters 96-912. The shutter is opened and closed in response to a shirt opening/closing signal from each measuring device, which will be described later.

When an opening signal is sent to each shutter, the corresponding shutter opens, and the potato chips are weighed by measuring devices 81 to 8 provided at positions corresponding to the shutters.
The arithmetic control unit N1 is sent to the 10 and is composed of a microcomputer having a processing unit, a memory, and an input/output device.
Based on the on/off signal f, the corresponding weighing device is driven. These measuring devices 81-81
0 is a well-known combination weighing device equipped with a microcomputer. This weighing device each includes a plurality of meters,
Potato chips, which are the objects to be weighed, are supplied from the opened shutter and are weighed after being supplied to each of these individual weighing machines, and these individual weight values are combined and added by a microcomputer. . The added weight value is then compared with the set weight value, and the optimal combination whose combination added weight value is equal to the set weight value or closest to the set weight value within the upper limit value is selected. Potato chips, which are the objects to be weighed, are fed into the hopper of the weighing machine and are discharged and sent to a packaging machine, which is not shown in the wIJ1 diagram, where they are packaged in bags or the like and shipped as products. . Note that the weight signal Wn of each weighing device is input to the arithmetic and control unit WIO. Further, the remaining potato chips that have been weighed in the conveyance lines A and B are returned to the conveyance lines A and H via lines A' and B''.

A signal q for controlling the supply speed of the supply device 1, line FDA, line F supply device 1, and distribution device 4 are supplied from the arithmetic and control device IO.

In this embodiment, the following control is further performed to prevent uneven seasoning due to changes in the amount of pot chips passing through the lines FDA and FDB. That is, each time the distribution control signal V is issued from the arithmetic and control device 10, the salt supply amount control signals dsa and dsb are issued to the salt sprinklers 5a and 5b to control the respective salt supply amounts. . In addition, a distribution control signal V is sent from the arithmetic control device 10.
Each time this is issued, flavoring material supply amount control signals dta and dtb are issued to the seasoning machines 7a and 7b, respectively, to control the supply amount of flavoring materials such as garlic powder and seaweed powder. The supply amount of flavoring materials such as salt, garlic powder, and seaweed powder may be controlled in direct proportion to the amount of potato chips distributed to each line and passing through them.

Next, control the allocation ratio to each line FDA and FDB,
Control of raw material supply rate and seasoning will be explained in detail using the flowchart shown in FIG. 4.

(1) The cumulative weight value Wa of the objects to be weighed on the transport line A and the cumulative weight value wb of the objects to be weighed on the transport line B stored in the memory of the arithmetic and control device i10 are cleared (step P1). Next, the combined weight values obtained by each of the weighing devices 81 to 810 are input to the arithmetic and control device io (step P
2).

In step P5, after calculating the cumulative weight value Wa of the transport line A and the cumulative weight value wb of the transport line B, it is checked whether a predetermined unit time (for example, 30 minutes) has elapsed since the start of weighing of each transport line ( Step P4).

(2) In step P5, the cumulative weight value W of the transport line A is
Determine whether a is within the appropriate range.

If Wa is within the appropriate range, it is checked in step P12 whether the cumulative weight value wb of the transport line B is within the appropriate range.

(3) If Wa exceeds the appropriate range, the arithmetic and control unit 10 calculates the distribution ratio of the distribution device 4 (step Ps), and checks whether the distribution ratio can be changed (step Ps). P7). The distribution ratio of each transport line is
There are certain restrictions in place to prevent excessive deflection to one conveyance line. If it is determined that the distribution can be changed, the distribution device 4 is operated to adjust the hl of the potato chips, which are the objects to be weighed, to be conveyed on each conveyance line (step Pa). In addition, when the hot water of the objects to be weighed transported by each transport line is adjusted in this step 2nd day,
The arithmetic and control unit IO sends supply amount control signals dsa and ds to the salt sprinklers 5a and 5b and the seasoning machines 7a and 7b, respectively.
b and flavored raw material supply amount control signals dta and dtb are issued to adjust the supply amount of salt and flavored raw materials, thereby making the seasoning uniform.

(4) If it is determined that the distribution change is not possible, the Wa
Check whether Wa is within the appropriate range (step Pg), and
If Wa exceeds the appropriate range, reduce the supply speed of the supply device 1 (Step P+o), and if Wa falls short of the appropriate range, increase the supply speed (Step P1I). 5 The object to be weighed supply control device according to the present invention achieves optimal weighing by (a) controlling the distribution ratio to each transport line and (b) controlling the raw material supply speed to each transport line. It is configured to be able to control the amount of material supplied. Furthermore, the arrangement is such that the seasoning of the objects to be weighed passing through each conveyance line is controlled at the same time.

Similarly to the transport line A, the transport line B also controls the distribution ratio (steps P15 to P15) and the supply device (
Step P17. Perform PI8).

In the above explanation, in addition to controlling the seasoning, there is also control of the distribution ratio,
The target is an example in which control of the raw material supply rate is also used.
In addition to controlling the seasoning, it is also possible to select and control only one of the above two types of controls.

1- In the embodiment, seasoning is controlled, distribution ratio is controlled,
The raw material supply rate is controlled based on the cumulative weight value obtained by accumulating the weight values obtained from each weighing device, but in addition to the cumulative weight value, for example, when each weighing device is used as a counting device, , the number of packages obtained from these may be controlled by the cumulative number of packages, or furthermore, the number of packages obtained from a packaging machine or the like may be controlled by the cumulative number of packages.

In addition, the object to be measured is not limited to potato chips as in the embodiment described above, and it goes without saying that other items may be used as the object.

(Effects of the Invention) As described above in detail, the wave meter material supply control device of the present invention is capable of controlling each weighing device when weighing objects to be weighed carried in from a plurality of conveyor lines by a plurality of weighing devices. Based on the cumulative weight value processed by the processing unit, an arithmetic and control unit composed of a microcomputer or the like automatically controls one or all of the feeding speed and distribution ratio of the feeding device. This allows optimal control of the supply of objects to be weighed. Moreover, since it is possible to perform flavoring control at the same time as performing such supply control of the objects to be weighed, it is also possible to achieve the effect of uniformly seasoning the objects to be weighed.
