<Combination weighing device and packaging device> FIG.
1 is a longitudinal sectional view schematically showing a combination weighing device 10.
As shown in FIG. 2, the combination weighing device 10 includes a supply device S
The weight of the product supplied from P is weighed for each weighing hopper, and a combination of weighing hoppers having a minimum error from a predetermined target weight is selected from among different combinations of the weighing results of the plurality of weighing hoppers. It is determined according to the result, and the merchandise stored in the weighing hopper of the determined combination is discharged to the packaging device 20.

More specifically, the commodity is supplied to the supply device SP
From FIG. 1, it is thrown into the supply chute 11 and thrown into the center of the distribution table 12. Further, each product is distributed to the radiation trough 13 and put into the pool hopper 14. Then, when there is a supply request, it is put into the weighing hopper 15. Then, the weight of the product supplied to each weighing hopper 15 is obtained. Thereafter, a calculation unit (not shown) determines an optimal combination of the weighing hoppers 15 that minimizes an error from a predetermined target weight, and selects an appropriate weighing hopper 15 according to the determination. Then, the goods stored in the selected weighing hopper 15 are collected by the collecting chute 17a, and are discharged by the discharging chute 17a.
b to the packaging device 20.

As a result, a group of commodities is divided into a group by weight near a predetermined target weight, and
Is discharged to The booster hopper 16 is provided between the weighing hopper 15 and the collecting chute 17a as necessary, and holds the product discharged from the weighing hopper 15 for a predetermined period until it is further discharged to the collecting chute 17a. It plays a role in regulating

This one combination weighing device 10 is
Dividing a plurality of weighing hoppers into two sections functions as combination weighing units C1 and C2 having a combination weighing function for two units. For example, when a total of 16 weighing hoppers 15 are provided in the combination weighing device 10, eight of the weighing hoppers 15 a to 15 a to 1 are provided.
A combination weighing unit C1 for performing combination weighing using 5h;
A combination weighing unit C2 that performs combination weighing using the individual weighing hoppers 15i to 15p can be configured. Then, it is possible to individually perform combination weighing for each of the combination weighing units C1 and C2. Therefore, for each of the separate weighing and packaging lines PL1 and PL2, each combination weighing section C1,
It is possible to provide each of the weighed products based on the results of the individual combination weighing for each C2.

Here, the combination weighing device 10 has two weighing modes, ie, a “double mode” and a “mix mode”, depending on how these combination weighing units C1 and C2 are used.

"Double mode" as one weighing mode
In, the weighing operation is performed independently in each of the two independent combination weighing units C1 and C2, and the products weighed to have a predetermined value in each of the combination weighing units C1 and C2 are separately provided. It is discharged to the packaging device 20 (and thus to a separate weighing and packaging line).

As described above, the "double mode" is a mode in which one combination weighing device 10 is divided and used in two independent weighing and packaging lines. The "double mode" can be referred to as a "shared mode" in which the combination weighing device is shared by a plurality of weighing and packaging lines, or a "non-exclusive mode" in which the combination weighing device is not exclusively used in a specific weighing and packaging line. It is.

In the "mix mode", which is another weighing mode, two independent combination weighing sections C1,
In C2, the weighing operation is performed independently, but the weighed products in each of the combination weighing units C1 and C2 are mixed and discharged to the same packaging device 20 (and therefore to the same weighing and packaging line). You. This “mix mode” is used, for example, when two independent combination weighing units C1 and C2 pack products weighed so as to have different target weights in the same bag, or when two different combination products weigh two different independent weights. Combination weighing section C1, C
After weighing each in step 2, it is used for bagging in the same bag. For the former example, 1
There is a case in which red candy and blue candy weighed by 00 g are packed in one and the same bag. As an example of the latter, 100 g and 50 g of 150 g of red candy are separately prepared. There is a case where the weight is measured and packed in the same bag. In these cases, the weighed products are placed in the same packaging device 2
In order to discharge to 0 (for example, the packaging device 20A), the discharge chute 17b is replaced with a type that discharges to one discharge port as shown in FIG. Note that FIG.
FIG. 2 is a longitudinal sectional view schematically showing the combination weighing device 10 in a mixed mode.

As described above, the “mix mode” corresponds to the two independent combination weighing sections C 1 and C 2 of the combination weighing apparatus 10.
In this mode, the products weighed in Step 2 are mixed and discharged to one weighing and packaging line. The “mix mode” is a mode in which the combination weighing device 10 is exclusively used in one of two (here, two) weighing and packaging lines, and is also referred to as “exclusive mode”. And In addition, this "exclusive mode"
In this mode, a weighing operation for a single target weight is performed using all the weighing hoppers. In other words, the combination weighing device 10 is weighed as one device having a combination weighing function without distinction between the combination weighing units C1 and C2. It also includes a mode in which the operation is performed. This is because such a mode can be understood as a mode in which all the weighing hoppers are exclusively used for one of the weighing and packaging lines PL.

There are roughly two types of setting parameters. This 2
The type parameters are “common parameters” and “commodity-specific setting parameters”.

First, the "common parameters" will be described.

As described above, the combination weighing device 10
Functions as two combination weighing units C1 and C2, and a setting parameter common to both of the two combination weighing units C1 and C2 (in other words, both of the weighing and packaging lines PL1 and PL2) is referred to as a common parameter. The common parameters include various setting parameters related to the operation of the scale associated with the weighing hopper 15 and the like. In addition, since the common parameter is a setting parameter related to the operation of the element shared by both the combination weighing units C1 and C2, it is also referred to as “operation parameter”.

FIG. 8 is a diagram showing an example of "common parameters" (or "operation parameters").

The common parameters include items related to “weighing mode setting”, “weighing setting”, and the like.

The "weighing mode setting" is a parameter for setting the combination weighing apparatus 10 to be operated in one of two weighing modes ("double mode" / "mix mode").

The "balance setting" is various setting parameters related to the balance, and any type (number) of the electric filters used in advance for noise removal or the like.
"Filter number" that determines whether to use the electrical filter of
It has various sub-items such as “stabilization time” that sets how long (time) the fluctuation of the weighing result in the weighing result is within a predetermined range and that the weighing state is considered to be stable. ing.

Next, another product-specific setting parameter will be described.

The “commodity-specific setting parameters” are setting parameters determined for each product. Further, there is a case where the combination weighing device 10 functions as two combination weighing units C1 and C2 and different products are supplied to the respective combination weighing units C1 and C2. In such a case,
Commodity-specific setting parameters include the combination weighing units C1, C2
It is preferable that each of them is determined separately for each of the weighing and packaging lines PL1 and PL2. Therefore, in this combination weighing device 10, each weighing and packaging line PL1,
Each product-specific setting parameter is stored in the storage unit 3 of the operation control device 30A, 30B corresponding to each of the weighing and packaging lines PL1, PL2 so that individual setting for each PL2 is possible.
2A and 32B. Specifically, the product-specific setting parameters for the weighing and packaging line PL1 are stored in the storage unit 32A of the operation control device 30A,
The product-specific setting parameters for the weighing and packaging line PL2 are stored in the storage unit 32B of the operation control device 30B. Note that the “product-specific setting parameters” are not the above-described operation parameters, and are therefore also referred to as “non-operation parameters”.

FIG. 9 is a diagram showing an example of the “setting parameter for each product”.

The “product-specific setting parameters” include “product name”, “product code”, “capability”, “weighing target value”,
It has various setting parameters such as “hopper opening / closing characteristics”, “timing”, and “section division selection”, and these parameters are set for each product.

The "product name" is an item representing the name of the product, and for example, names such as "xx candy" (product A) and "@ potato" (product B) are given.

The “product code” is an item containing an identification symbol or the like assigned to identify each product, and is, for example, 1000 for product A and 200 for product B.
A number such as 0 is assigned.

"Capability" is an item indicating the processing capacity of weighing, and is expressed by the number of times of weighing performed per minute. For example, it is represented by a numerical value such as 50 times per minute.

"Target weighing value" is a parameter for setting a target weight in one combination weighing operation. For example, when 100 grams is set, some weighing hoppers are determined so that the total of the products stored in the weighing hopper becomes 100 grams, and the total of 100 grams of the product is sent to the packaging device 20. Will be discharged.

The "hopper opening / closing characteristics" are parameters relating to the opening / closing characteristics of the weighing hopper 15, and include "stepping motor excitation type", "stop delay pulse number", "minimum output pulse number", "drive stop condition", "actuator stop condition", and "actuator stop condition". , “Drive power”, “error detection pulse number”, “brake holding time”, “drive pattern”, and other sub-items. For example, “stepping motor excitation type” is a parameter that sets the excitation type of the stepping motor that opens and closes the weighing hopper.
The “stop delay pulse number” is a parameter for setting the number of pulses in the slit signal from when a condition for stopping driving is first satisfied until the motor is actually stopped.
The “actuator type” is a parameter indicating the type of the actuator, such as whether it is a stepping motor or an air cylinder. The “drive power” is a parameter for setting the drive torque of the motor, and the “error detection pulse number” is a parameter for setting the reference pulse number when detecting a defective operation of the motor. "Brake hold time" is a parameter that sets the time to hold the excitation of the stepping motor and apply the brake after the drive stops and the motor stops, and the "drive pattern" selects the operation pattern during driving. Parameters to perform.

"Timing" is a parameter for setting various timings, and this parameter also has various sub-items. These sub-items include, for example, “time from when the weighing hopper 15 operates to when the pool hopper operates” and “the packaging device 20”.
From when the discharge request signal is input to when the weighing hopper 15 operates.

The "section division selection" means that when the combination weighing device 10 is divided into two combination weighing sections C1 and C2, a plurality of (for example, 16) weighing hoppers 15 are divided into two.
It is a parameter that determines how to divide into two sections A and B. Specifically, it is determined which weighing hopper is to be allocated to section A and which weighing hopper is to be allocated to section B. These setting parameters are determined such that, for example, eight weighing hoppers 15a to 15h are allocated to section A, and eight weighing hoppers 15i to 15p are allocated to section B. Alternatively, by changing this parameter, six weighing hoppers 15a to 15f are allocated to section A, and ten weighing hoppers 15g to 15g are allocated to section B.
15p can be assigned.

<B. Operation> The operation control device 30 has various menu screens hierarchized. The operator changes the above various setting parameters by selecting and using a menu screen of an appropriate hierarchy. Hereinafter, the changing operation of the setting parameter will be described.

<First Operation> First, the combination weighing device 10
A description will be given of the processing when the operation of changing the setting parameter is attempted during the operation of the above. In the first operation, a case where “common parameters” are changed as setting parameters will be described.

FIG. 10 is a diagram showing a state transition relating to a setting parameter changing operation of the operation control device 30.

As shown in FIG. 10, after the power of the operation control device 30 is turned on and a predetermined process is completed, the process shifts to a state ST10 in which setting parameter change can be permitted.

In this state ST10, none of the weighing and packaging lines PL1 and PL2 is operating (therefore, the combination weighing device 10 is not operating), and the setting parameters are not set by any of the operation control devices 30A and 30B. Is not being changed.

In this state ST10, when a change request relating to the setting parameters of the combination weighing device 10 is input through one of the operation input units 31A and 31B of the operation control devices 30A and 30B, the change request is transmitted. The state may be shifted to a state ST20 in which the operation is permitted and the change operation is possible.

For example, in this state ST10, when a request to permit setting of a common parameter is transmitted by the operation control device 30A, the request to permit setting is accepted, and the operation input by the operation control device 30A is performed.
The process moves to 20 (see arrow AR1).

More specifically, when an operation input relating to a change of a setting parameter is performed using the operation input unit 31A (see FIG. 6) of the operation control device 30A in the state ST10, first, the control unit 34A of the operation control device 30A is started. Sends a setting permission request to the intermediate unit 19 via the communication unit 33A. The intermediate unit 19 stores a state parameter indicating the current state. When the intermediate unit 19 confirms that the current state is the state ST10 by referring to the value of the state parameter, the operation control device 30A Is transmitted to the operation control device 30A. The intermediate unit 19 transmits the acceptance signal, and changes the value of the state parameter to a value indicating the state ST20, thereby shifting the current state of the weighing and packaging system 1 to the state ST20.

FIG. 11 is a diagram showing an example of a screen displayed on the operation input unit 31A when an operation input of a setting parameter (here, "stabilization time") relating to the scale is performed in the operation control device 30A. In state ST20,
For example, using such a screen, it is possible to change an operation parameter relating to the stabilization time of the balance, which is one of the common parameters. The operator can set the stabilization time to a desired time by changing the value in units of 100 milliseconds and / or 10 milliseconds using arrow keys or the like indicating the up and down directions.

The contents of the setting parameters changed by the operation control device 30A in this state ST20 are stored in the storage section 32A of the operation control device 30A, and are also transferred to the intermediate unit 19 to be transferred to the intermediate unit 1
9 is stored in a predetermined storage area. As a result, the setting parameters stored in the intermediate unit 19 have the newest contents. Further, the intermediate unit 19 also rewrites the setting parameters stored in the storage unit 32B of the operation control device 30B to the same contents. In this way,
The intermediate unit 19 synchronizes the setting parameters in the storage unit 32A with the setting parameters in the storage unit 32B.

Here, in state ST20,
Only the operation control device 30A that has received the setting permission request is
It is possible to change the setting parameters of the combination weighing device 10 and the like. On the other hand, in this state ST20, the setting permission request from the other operation control device 30B is rejected, and the operation control devices other than the operation control device 30A (specifically, the operation control device 30B) change the setting parameters. Can not do. Thereby, it is possible to avoid inconsistency in the setting parameters in both operation control devices 30A and 30B.

After the setting parameter change processing is completed after the predetermined setting parameter change processing, the operation control device 30A sends a signal notifying the end of the setting change operation to the intermediate unit 19, and Is changed to a value representing the state ST10. Thereby, the weighing and packaging system 1 returns to the state ST10 again, and any of the operation control devices 30A and 30B.
The setting permission request from is also accepted. In addition, as an exceptional process, when the communication line is disconnected for a certain period of time, for example, when the power supply is interrupted for some reason in the state ST20, the state ST20 is changed to the state ST10.
May return to.

In the above description, a case has been described in which the operation controller 30A sends a common parameter setting permission request in the state ST10. However, a case where the operation controller 30B sends a common parameter setting permission request is also described. The same is true.

Next, in the state ST10, when the operation start command is sent from the operation control device 30A or 30B to the combination weighing device 10,
The operation of the weighing and packaging line PL including the combination weighing device 10 is started. At this time, the intermediate unit 19 changes the value of the state parameter to a value indicating that the combination weighing device 10 is operating, and changes the state of the weighing and packaging system 1 to the state S.
The process proceeds to T30.

Then, in this state ST30, the intermediate unit 19 rejects any common parameter setting permission request from any of the operation control devices 30A and 30B.
Thereby, while at least one of the weighing and packaging lines PL1 and PL2 is operating (that is, the combination weighing device 1).
0 is operated), even when the operation control device 30 of another weighing and packaging line requests a change of the setting parameter for the common parameter of the combination weighing device 10, Storage units 32A, 32B of operation control devices 30A, 30B relating to parameters
Can be prevented from causing inconsistencies (or discrepancies) in the setting contents.

For example, a case will be described in which the operation control unit 30B of another weighing and packaging line PL2 requests a change of the set parameter using the operation input unit 31 during the operation of the weighing and packaging line PL1.

In this case, the control unit 3 of the operation control device 30B
4B (see FIG. 6), upon receiving an operation input from the operation input unit 31B, sends out a setting parameter setting permission request for the combination weighing device 10 to the intermediate unit 19 via the communication unit 33B. On the other hand, the intermediate unit 19 refers to the state parameter indicating whether the weighing and packaging line PL1 is currently operating or not, and determines that the other weighing and packaging line PL1 is currently operating and is in the state ST30. If confirmed, a rejection signal for rejecting the setting permission is sent to the operation control device 30B. That is, the intermediate unit 19 includes the operation control device 30 for the weighing and packaging line PL2.
The request for the change of the setting parameter from the B side is rejected. As a result, the operation control device 30B stores its own storage unit 32
The setting parameters stored in B cannot be changed, and the setting parameters stored in the storage area in the intermediate unit 19 cannot be changed.

As described above, in the intermediate unit 19, when one weighing and packaging line PL1 is operated, the operation input indicating that the setting parameter should be changed is performed by the operation input unit 31B of the other line operation control device 30B. in case of,
During the operation of the weighing and packaging line PL1, at least the synchronous operation of the set parameters is prohibited. As a result, inconsistencies (or discrepancies) occur in the setting contents in the storage units 32A and 32B of the operation control devices 30A and 30B regarding the common parameters (operation parameters) of the combination weighing device 10 shared by the two weighing and packaging lines PL1 and PL2. Can be prevented.

Here, the case where the request for changing the setting parameter is immediately rejected during the operation of the combination weighing apparatus 10 has been described as an example, but the present invention is not limited to this. The change request may be received and buffered, and then, when the combination weighing device 10 is in the non-operation state, the change of the setting parameter may be made valid.

For example, the intermediate unit 19 operates during the operation of the weighing and packaging line PL1 (therefore, the combination weighing device 10).
The change request of the setting parameter received during the operation of (1) is temporarily buffered. At this time, the changed content is not yet reflected on the content of the setting parameter. And
When the weighing and packaging line PL1 is brought into the non-operation state, the operation parameter is automatically changed in response to the buffered change request, thereby automatically changing the operation parameter in the intermediate unit 19. To enable.

More specifically, a buffer area is prepared in the intermediate unit 19, and a buffer area is also prepared in the storage section 32B of the operation control device 30B. Then, when an operation input indicating that the operation parameter should be changed is performed during the operation of the weighing and packaging line PL1 (therefore, during the operation of the combination weighing device 10), the change of these parameters is not enabled, and The change reservation parameter is stored in the buffer area of (1). Then, when the weighing and packaging lines PL1 and PL2 both become inactive and shift to state ST10, in response to the change request, state S
The process moves to T20. Then, the contents of the change reservation parameters stored in the buffer area of the intermediate unit 19 are written into the storage area of the intermediate unit 19 as the contents of the corresponding operation parameters, and the operation stored in the buffer area of the storage unit 32B. The contents of the parameters are also written in the storage unit 32B of the operation control device 30B, and the same contents are also written in the storage unit 32A of the operation control device 30A. Thereby, the change of the operation parameter of the combination weighing device 10 can be made effective, and the storage unit 32A and the storage unit 32B can be synchronized. Further, when both of the weighing and packaging lines PL1 and PL2 shift to the non-operation state, the setting parameters can be automatically changed, so that the operability is improved.

[0091] The return from the state ST30 to the state ST10 occurs when the operation stop command is sent from the operation control device 30A or the operation control device 30B to the combination weighing device 10, or the communication line for a certain period of time as an exceptional process. Is disconnected.

<Second Operation> Next, the change of the weighing mode will be described. As described above, the common parameters (operation parameters) include parameters for setting the weighing mode. The weighing mode includes (1) an exclusive mode (mix mode) in which the combination weighing device 10 is monopolized by one weighing and packaging line, and (2) a combination weighing device 10.
And a shared mode (double mode) in which the same is shared by a plurality of weighing and packaging lines.

FIG. 12 is a state transition diagram showing the transition of the weighing mode. As shown in FIG. 12, in the combination weighing device 10, there are a case where the mode changes from the double mode to the mix mode and a case where the mode changes from the mix mode to the double mode.

First, when the combination weighing device 10 is operating, the intermediate unit 19 rejects the request for changing the weighing mode, and the change of the setting parameter related to the weighing mode is not permitted in any direction. That is, the intermediate unit 19 does not permit a change request from the double mode to the mix mode, nor does it permit a change request from the mix mode to the double mode.

For example, when the combination weighing device 10 is operating in the double mode, the intermediate unit 19 transmits from the operation control device 30A a request to change the setting parameter relating to the weighing mode to immediately change the weighing mode to the mix mode. Also, when the change request is rejected, and the operation control device 30B transmits a request to change the setting parameter related to the weighing mode to immediately change the weighing mode to the mix mode, the change request is rejected. .

Similarly, even when the combination weighing device 10 is operating in the mix mode, the intermediate unit 19
When a request to change the setting parameter related to the weighing mode to immediately change the weighing mode to the double mode is transmitted from the operation control device 30A, the request for the change is rejected, and the weighing mode is changed from the operation control device 30B to the double mode. When a request for changing the setting parameter relating to the weighing mode for immediate change is transmitted, the request for change is rejected.

Next, a case where a request for changing the weighing mode is made while the combination weighing device 10 is stopped will be described.

When the combination weighing device 10 is stopped and the combination weighing device 10 is set to the double mode, the intermediate unit 19 is operated by the operation control device 30A to immediately change the weighing mode to the mix mode. Permits a request to change setting parameters for Thereby, the weighing mode is changed from the double mode to the mix mode.

For example, while the combination weighing device 10 is stopped, the operation input unit 31A of the operation control device 30A
A case where the weighing mode is changed will be described.

FIG. 13 is a diagram showing an example of the screen of the operation input unit 31A when the weighing mode is switched. The operator performs an operation input indicating that the weighing mode should be changed from “double” to “mix” by pressing a portion of the screen where “mix” is displayed with a finger.

In response to the operation input, the operation control device 3
OA transmits to intermediate unit 19 a setting parameter change request to immediately change the weighing mode to the exclusive mode (mix mode) in which combination weighing device 10 is monopolized by its own weighing and packaging line PL1. In response, the intermediate unit 19 grants this change request. In this manner, the weighing mode is changed from the shared mode (double mode) in which the combination weighing device 10 is shared by the two weighing and packaging lines PL1 and PL2 to the exclusive mode (in which the weighing and packaging line PL1 exclusively uses the combination weighing device PL). Mixed mode)
Is changed to

On the other hand, when the combination weighing device 10 is set to the mix mode, even when the combination weighing device 10 is stopped, the combination weighing device 10 is connected to a weighing and packaging line other than the weighing and packaging line that monopolizes the combination weighing device 10. The operation differs from the above case in that the change of the weighing mode from the corresponding operation control device 30 is not permitted.

For example, it is assumed that the combination weighing device 10 is set to the exclusive mix mode by the weighing and packaging line PL1. At this time, the intermediate unit 1
9 recognizes that the mode has shifted to the exclusive mode by the weighing and packaging line PL1, and the other weighing and packaging line PL2
Does not accept a request to change the setting parameter related to the weighing mode from the operation control device 30B. In other words,
When the combination weighing device 10 is set to the mix mode monopolized by the weighing and packaging line PL1, the intermediate unit 1 is set even when the combination weighing device 10 is stopped.
No. 9 rejects a change request from the operation control device 30B corresponding to the other weighing and packaging line PL2 to immediately change the weighing mode to the double mode.

As described above, the operation control device 30B cannot change the setting parameters of the combination weighing device 10. In short, the operation control device 30B is
It is in a state of being "cut off" from the weighing and packaging system 1 with respect to the change of the setting parameter. Therefore, it is possible to prevent the operation control device 30B of the weighing and packaging line PL2 that is not in use from changing the setting parameters related to the combination weighing device 10 by mistake.

At this time, as shown in FIG. 14, on the display screen of the operation input unit 31 of the operation control device 30B, the weighing mode of the combination weighing device 10 is set to the exclusive mode by another weighing and packaging line PL1. It is preferable to display an indication that the own weighing and packaging line PL2 cannot be used when it is in use. This is because such a display allows the operation control device 30B belonging to the weighing and packaging line PL2 to notify the operator that the setting of various parameters cannot be changed.

<Third Operation> Next, the operation at the time of turning on the power (at the time of starting) will be described. Specifically, as shown in FIG. 15, the power is turned off (OF) in each operation control device 30.
When the operation control device 30 shifts from the state of F) to the power-on (ON) state, each of the operation control devices 30
In response to the activation of 0, the latest setting parameters (more specifically, common parameters) in the other-line operation control device 30 are copied to its own storage unit.

More specifically, when the power switch of the operation control device 30A is switched from the off state to the on state and the operation control device 30A is supplied with power, the operation control device 30A All the common parameters stored in the area are copied to the storage unit 32A in the own operation control device 30A.

Here, the other-line operation control device 3
If the contents of the common parameters in 0B are changed, the latest changes made by the operation control device 30B are stored in the storage area of the intermediate unit 19. The contents are always memorized. Therefore, the contents of all the common parameters stored in the intermediate unit 19 are stored in the operation control device 30.
By copying to the storage unit 32A of A, the latest contents of the common parameters of the operation control device 30B are copied to the storage unit 32A of the operation control device 30A.

In this way, the intermediate unit 19
When one operation control device 30A is started, the common parameters stored in the storage unit 32A of one operation control device 30A are synchronized using the latest one of the common parameters in the other line operation control devices 30B.

Here, the case where data relating to all common parameters is copied has been described. However, the present invention is not limited to this, and only the difference data of the changed portion may be copied. Specifically, the intermediate unit 19 is stored in the storage unit 32A of the other line operation control device 30B and the common parameters stored in the storage unit 32A of one operation control device 30A before starting. The difference from the common parameter may be copied to the storage unit 32A. This also allows the storage unit 32A
Can be updated to the latest content, and the storage content of the storage unit 32A and the storage content of the storage unit 32B can be synchronized.

<Fourth Operation> Next, a copy operation relating to a setting parameter for each product among the setting parameters will be described.

This copy operation is mainly performed while the operation is stopped. Hereinafter, a specific description will be given of a case where data stored in the storage unit 32A of the operation control device 30A is copied to the storage unit 32B of the operation control device 30B with respect to the product-specific setting parameters.

FIG. 16 is a diagram showing setting parameters related to product-specific settings stored in each of the storage units 32A and 32B. As shown in FIG. 16, each storage unit 32A, 3A
2B is No. 2 respectively. 1 to No. There is an area for storing setting parameters (see FIG. 9) for each of the 50 types of products for 50 types of products. More specifically, the storage unit 32
A is a setting parameter NA1 for each of the 50 types of products.
To NA50, and setting parameters NB1 to NB50 for each of the 50 types of products are also stored in the storage unit 32B. In addition, each of these parameters NA1 to NA1
Each of the NAs 50 and NB1 to NB50 has a plurality of items described above (for example, “product name” and “hopper open / close characteristics”).

Here, a case will be described in which parameters relating to one product (here, the product of No. 3) stored in the storage unit 32A are copied to the storage unit 32B.

First, the operator uses the operation input unit 31A to select a predetermined product (here, N
o. An operation input to the effect that the setting parameter for each product (product No. 3) should be changed. The control unit 34A changes the contents of the setting parameters for each product stored in the storage unit 32A according to the operation input.

FIG. 17 is a diagram showing an example of a screen displayed on the operation input unit 31A when a setting parameter relating to "hopper opening / closing characteristics" which is one of the setting parameters for each product is changed. The operator can change the operation parameters relating to the “hopper opening / closing characteristic” using such a screen, for example. When the operator touches the display part with the name of each item in FIG. 17, the menu screen of the next hierarchy is displayed on the operation input unit 31. The operator
By using the new menu screen, each operation parameter can be operated and input.

Here, the measuring and packaging lines PL1, P
Since L2 sometimes handles different products,
The setting parameters for each product can store different contents between the operation control device 30A and the operation control device 30B. That is, this operation using the operation input unit 31A changes only the setting parameters for each product in the storage unit 32A, and the setting parameters for each product in the storage unit 32B are not affected at all.

Incidentally, in this weighing and packaging system 1, it is assumed that similar products are handled on the weighing and packaging lines PL1 and PL2. In such a case, there is a case where the result of changing the setting parameter in the operation control device 30A is also desired to be reflected in the operation control device 30B. In such a case, the operability can be improved by performing the following copy operation.

More specifically, the operator of the operation control device 30A first converts the product-specific setting parameters for the predetermined product in the operation control device 30A into the product-specific setting parameters for the predetermined product in the operation control device 30B. An operation input for performing an operation of copying in units is performed. For example, the No. in the storage unit 32A. An instruction is given to copy the product-specific setting parameter NA3 regarding the product No. 3 to the product-specific setting parameter NB3 in the storage unit 32B. In response, the intermediate unit 19 confirms that the product-specific setting parameter NB3 is not the parameter currently in use, and then stores the No. in the storage unit 32A. The product-specific setting parameter NA3 for the product No. 3 is copied to the product-specific setting parameter NB3 in the storage unit 32B, and the product-specific setting parameters are synchronized between the plurality of operation control devices 30A and 30B.

According to this, the operator can control the operation control device 3
It is not necessary to repeatedly input the same change content as in the operation control device 30A in 0B, and operability can be improved. At this time, the intermediate unit 19 determines that the setting parameter NB3 of the change destination is the currently operating combination weighing device 1
At 0, the synchronous operation is performed after confirming that the parameter is not the setting parameter relating to the product being processed. Therefore, it is possible to prevent the contents of the setting parameter from being changed during operation.

As described above, the changing operation and the synchronizing operation of the common parameters are prohibited during the operation of the combination weighing apparatus 10 with respect to the common parameters. Regarding the above, even during the operation of the combination weighing device 10, the change of the product-specific setting parameters for the products other than the products being processed may be permitted. In this case, even when the combination weighing device 10 is operating with another product as a processing target, the operation of changing and synchronizing the product-specific setting parameters for the predetermined product can be performed, so that the flexibility in system operation is improved. .

In the above, both storage units 32A,
Although the case of synchronizing the parameters of the same number (No. 3) in 32B has been exemplified, the present invention is not limited to this, and different numbers (for example, No. 3) are used in both storage units 32A and 32B.
5, No. 48) The parameters may be synchronized.

<C. Others> In the above embodiment,
The weighing and packaging system 1 having the two operation control devices 30A and 30B separately provided for the two weighing and packaging lines PL1 and PL2 sharing one combination weighing device 10 has been described, but the present invention is not limited to this. For example, the present invention can be applied to a weighing and packaging system in which one operation control device 30 is shared by three or more weighing and packaging lines PL.

In the above-described embodiment, when setting the setting parameters for each product (FIG. 9), the contents of a plurality of items relating to the hopper opening / closing characteristic parameters are individually and independently set (for each product). Although the case is illustrated (see FIG. 17), the present invention is not limited to this, and it is also possible to collectively set the setting parameters for each product over a plurality of items. For example, combinations of contents (set values) of a plurality of items included in the hopper opening / closing characteristic parameter among the setting parameters for each product are grouped, and the plurality of groups are stored (registered) in advance in a predetermined table, The operator may designate the number (group number) of any one of the plurality of groups by using the operation input unit 31. According to this, the contents regarding the plurality of items included in the hopper opening / closing characteristic parameters are collectively set so as to be the contents corresponding to the respective items of the group of the designated number.

[0125]

As described above, according to the first aspect of the present invention, the synchronizing means changes the setting parameter of another weighing and packaging line in one of the plurality of operation control devices. When the operation input to the effect is performed, at least the synchronization of the operation parameters is prohibited during the operation of the weighing device of another weighing and packaging line, so that the setting parameter stored in each of the plurality of operation control devices is set. Can be synchronized without contradiction.

According to the second aspect of the present invention, the synchronization means buffers the operation parameter change request received during the operation of at least one of the plurality of weighing and packaging lines, and executes the weighing and packaging line. Enables changes in operating parameters when becomes inactive,
The setting parameters stored in each of the plurality of operation control devices can be synchronized without inconsistency and with improved operability.

According to the third aspect of the present invention, when the combination weighing device is operating, the synchronization means rejects the weighing mode change request, so that the weighing mode can be prevented from being erroneously changed.

According to the fourth aspect of the invention, when the combination weighing device is set to the exclusive mode, the synchronization means monopolizes the combination weighing device even when the combination weighing device is stopped. Since a request to change the weighing mode to the shared mode from the operation control device corresponding to the weighing and packaging line other than the weighing and packaging line is rejected, the operation control device capable of changing to the shared mode is limited to one operation control device. This can more reliably prevent erroneous operation.

According to the fifth aspect of the present invention, each of the plurality of operation control devices can control its own weighing and packaging line when the weighing mode of the combination weighing device is set to the exclusive mode by another weighing and packaging line. Is further provided with a display means for indicating that the weighing and packaging line cannot be used, so that the operator can easily know that the weighing and packaging line cannot be used.

According to the sixth aspect of the present invention, the synchronization means responds to the activation of one operation control device by using one of the latest setting parameters in the other line operation control device. Since the setting parameters stored in the storage means of the operation control device are synchronized, it is possible to synchronize the setting parameters stored in each of the plurality of operation control devices without inconsistency at the time of startup.

According to the seventh aspect of the present invention, the synchronizing means stores the setting parameters stored in the storage means of one operation control device before starting and the storage means of the operation control device for another line. Since the difference from the stored setting parameter is copied, the amount of information to be copied can be suppressed and synchronization can be efficiently achieved.

According to the eighth aspect of the present invention, the synchronizing means synchronizes the setting parameters for each product among the plurality of operation control devices, so that the synchronization parameters are stored in each of the plurality of operation control devices. Can be synchronized without contradiction.
