Conventional technology Conventionally, in a fully automatic labeling system, an incoming conveyor, a weighing conveyor, and a pasting conveyor are installed in series, and the operation of each conveyor is controlled independently to ensure smooth product transfer. ing. In other words, the time for weighing the product;
In order to achieve the shortest and most efficient processing time even when appropriate timings such as label printing time are combined, each conveyor is equipped with a sensor that detects the product, and the output of this sensor and the weighing device is The operation timing of each conveyor is determined by combining the following.

Problems to be Solved by the Invention However, this control system only ensures that the conveyance of products is carried out smoothly by weighing and labeling, and if the supply of products is interrupted, all conveyors will stop working. It is in working condition. Furthermore, product supply is not always continuous, and there may be interruptions, and continuous operation of the conveyor at such times increases power consumption and shortens the lifespan of the equipment. This means that noise is constantly generated, which is not desirable.

The present invention has been made in view of the above points, and an object of the present invention is to provide an intermittent operation device for a conveyor in a fully automatic labeling system that can reduce power consumption by operating the conveyor only when necessary. It is.

Means for Solving the Problem A carry-in conveyor, a weighing conveyor, and a pasting conveyor, each of which is operated independently, are installed in series, and a sensor for detecting products is provided on each of these conveyors, and a sensor is installed on each of these conveyors to detect products. A predetermined time is set based on the product detection by the sensor, and if no new product is detected during the predetermined time, the weighing conveyor and the pasting conveyor are stopped, and if the product is detected during the predetermined time, the weighing conveyor and the pasting conveyor are stopped. An intermittent timer is provided to put the pasting conveyor into operation.

Function When the supply of the product is interrupted and a predetermined period of time has elapsed, the weighing conveyor and the pasting conveyor will stop until the product is supplied again and detected by the sensor.
This allows the conveyors to be operated only when necessary, except for the carry-in conveyor.

Next, based on FIG. 5, the timing of each part when issuing a single-stage printed label 89 as shown in FIG. 6 will be explained. Printing at this time includes processing date, unit price, weight, price, department code, etc. First, V ₁ sensor 7 (displayed as V ₁ S)
When detects a product, V ₁ SF goes up and at the same time, V ₁ timer (V ₁ T) sets a certain time T, and after time-up, V ₁ TF goes up. Then, due to the time-up of V ₁ T, V ₁ SF = 0, and V ₁ sensor 8
(displayed as V ₂ S) detects a product, it sets up V ₂ SF and at the same time starts load cell SL4.
Then, the conveyor V ₁ 1 is started with the first signal of the load cell SL4, and V ₂ TF is also set up. The load cell SL4 is set to always generate two signals, and the second signal is used to take in weighing data and perform other necessary operations. Next, V ₃ sensor 9 (displayed as V ₃ S)
When the product is detected by V ₂ SF=0, V ₂ TF=
0, setting V ₃ SF, starting print work, and starting the V ₃ timer (V ₃ T) are performed at the same time. And _V3
Printing is completed and the label is fed during the time set by the timer, and after that is completed, label pasting (STICK) is started when the V ₃ timer is set up under the condition that V ₃ S ₂ F = 1, which is generated in the main routine described later. It will be done. In addition, INT HOLD
The portion labeled as ``'' indicates that various types of interruptions will be made, which will be described later.

Next, based on FIG. 7, the timing of each part when issuing a two-stage printed label 90 as shown in FIG. 8 will be explained. At this time, in addition to the above-mentioned one-line printing, the effective date, tare weight, product code, etc. are printed on the second line. first,
Load cell SL from product detection by V ₁ sensor 7
The conditions up to the 4th start are similar to those shown in FIG. However, the start of the conveyor V ₁ 1 is performed after the time T has elapsed since V ₂ SF=0. When the V ₃ sensor 9 detects the product, V ₂ SF = 0, V ₃ S ₁ F = 1, the V ₃ timer is started, the first stage is printed, and the first stage feed is started. Then, perform the second stage printing and perform the second stage feeding. If the V ₃ timer times up before these tasks are completed, the product has reached the labeling position and the V ₃ S ₂ F is erected and the conveyor is moved.
V ₃ Stop 3. At the end of the second stage feeding, the preparation for label pasting is complete, so label pasting (STICK) is performed after a certain period of time from that point.
V ₃ S ₂ F=0, and the conveyor V ₃ 3 restarts.

Even if the conveyor is set to a two-stage feed state, if the _V3 timer is not set up for some reason, the conveyor _V33 will not stop and will continue to operate, but when the _V3 timer is delayed and set up, Labeling is done while the conveyor _V33 is in operation.

Various business interruptions will now be explained based on FIGS. 9 to 15. First, what is shown in FIG. 9 is the interrupt INT V ₁ S of V ₁ sensor 7.
In this state, V ₁ SF=1 and V ₁ TF
A check to see if = 1 and a check to see if V ₂ SF = 1 are performed in sequence, and when either one is standing, the conveyor V ₁ 1 is stopped, and when neither is standing, the V ₁ timer is started. Next, _V3S2F checks whether _{the V3} sensor 9 detects the product.
V ₃ S ₂ When F=0, conveyor V ₂ 2 and conveyor
V ₃ 3 is started, and when V ₃ S ₂ F=1, the start of conveyor V ₂ 2 and conveyor V ₃ 3 is jumped and the ACLF is checked to see if it is in an auto zero state. When ACLF = 0, it resets the intermittent timer and returns, and when ACLF = 1, it resets the intermittent timer and returns.
Set end F=1 and start load cell SL4.
After turning it OFF, reset the intermittent timer and return.

Next, what is shown in Figure 10 is the interrupt of the V ₁ timer, and when this occurs, V ₁ TF = 1, and V ₁ SF
= 0, reset the V ₁ timer, and set INT V ₁ S
Reset.

In addition, the one shown in FIG. 11 is the V ₂ sensor 8
When this interrupt occurs, V ₂ SF = 1,
Check the measurement F after setting V ₁ TF = 0.
If weighing F=1, start load cell SL4 with print data -1F=1 and return.
If weighing F=0, set SL start F=1, start load cell SL4, then turn OFF and return. Therefore, even in the case of fixed printing, the load cell SL4 is started in the same manner as in automatic weighing, thereby making the start timing of each task exactly the same as in automatic weighing.

Furthermore, what is shown in FIG. 12 is an interrupt of the _V2 timer, and at this time, the double-stroke switch 67 is activated.
Check double stroke F to see if it is ON. In the case of two-stage printing, the conveyor V ₁ 1 is started according to the product detection state of the V ₃ sensor 9 described later, and in the case of one-stage printing, V ₂ TF = 1,
After setting V ₂ SF=0, start the conveyor V ₁ 1. Then, whether it is one-stage printing or two-stage printing, V ₁ SF is checked, and when V ₁ SF = 0, V _{1 SF is} checked.
Reset the start timer and return.
When V ₁ SF=1, start the V ₁ timer.
Check ACLF. If it is not auto-zero, reset the V ₁ start timer as described above and return. If ACLF = 1, set ACLF end F = 1, turn off the start of load cell SL4, reset the V ₁ start timer, and return. do.

Next, what is shown in Fig. 13 is the interrupt of the V ₃ sensor 9. When this occurs, it checks the double stroke F, and if the double stroke F = 1, it sets V ₂ SF = 0 and starts the V ₁ start timer. If double stroke F=0, jump these and check the measurement F.
If weighing F=0, set print ready F and weighing F
If = 1, jump it and make V ₃ S ₁ F = 1,
Set V ₂ TF=0, start V ₃ timer, INT
V ₂ S reset and return.

Also, what is shown in Fig. 14 is the interrupt of the V ₃ timer. When this occurs, the double-stroke F is checked, and if the double-stroke F = 0 and the single-stage printing is in progress, V ₃ S ₂ F is executed.
When = 1, spray the label to make V ₃ S ₂ F = 0,
When V ₃ S ₂ F=0, the V ₃ timer is directly reset and the process returns. Next, in the two-stage printing state, that is, when two-stage printing F = 1, check V ₃ S ₁ F. If V ₃ S ₁ F = 1, it means that the preparation for label printing is not completed. , at this time
V ₃ S ₂ F=1, V ₃ S ₁ F=0, conveyor V ₃ 3
Stops and returns after resetting the _V3 timer. Also, when the double hit F=1 mentioned above,
When checking V ₃ S ₁ F, if V ₃ S ₁ F = 0, check V ₃ S ₂ F, and if V 3 S ₂ F = 1, V _{3 S 2} F
= 0, then spray the label and conveyor V ₃
3, reset the _V3 timer and return.

Next, based on Fig. 15, load cell SL4
This section explains the interrupt. This load cell SL
After the start of Step 4, the weight count number is loaded, then the weighing F is checked, and if the weighing F = 1, the print data -2F is checked, and if the print data -2F = 1, it is first set to 0, and the print ready F is checked. = 1, put the weight count number in wait count register-1 85, display data F = 1, ACLF = 0, ACL counter = 0, ACL-2F = 0, ACL end = 0.
Return as. Also, if print data -2F = 0, check print data -1F, and if print data -1F = 1, set it to 0.
and set print data -2F=1, start OFF load cell SL4, and if double stroke F=0, V ₁
Start the start timer and double hit F=1
Then jump it and display data F=
0, and returns as ACLF=0, ACL counter=0, ACL-2F=0, and ACL end F=0 as described above.

Furthermore, when the aforementioned print data -1F = 0 or the aforementioned measurement F = 0, ACLF is checked, and if ACLF = 1, +1 is added to the ACL counter.
Check whether ACL counter = 2.
If ACL counter = 2, set ACL counter to 0,
Set ACL-2F=1, put the weight count number into the weight count register-1 85, and set display data F=1. In addition, if the ACL counter is not 2, set ACL-2F to 0 and set the weight count number to wait count register-2 87
and set the display data F=0. Next, check ACL end F, and if ACL end F = 0, return as is, and check ACL end F.
= 1, ACLF = 0, ACL counter = 0, ACL
End Returns as F=0.

Furthermore, when checking the ACLF mentioned above, ACLF=
When it is 0, check the measurement F again, and if the measurement F = 1, return as is, and if the measurement F = 0, check the SL start F, and start the SL.
If start F = 0, return, SL start F
If so, set it to 0, then check the double stroke F, and if the double stroke F=0, start the V ₁ start timer, and if the double stroke F=1, jump it and set the display data F=0. Return. This means that even in the case of fixed printing, the timing of each job is set based on the start of the load cell SL4.

Next, the main flow will be explained based on FIGS. 16 to 18. First, in FIG. 16, after the power switch 27 is turned on, I/reset and initialization of each part are performed, and a check is made to see if the double-stroke switch 67 is turned on. If this is ON, double hit F=
1, and when it is OFF, the double-stroke F=0 is set, and the business switch is read between . The content of this business switch reading is based on the switching switch 31 being in the automatic issuing position.
Is APF=1 or its switch 31?
The first is whether the switch 31 is in the manual issue position and the MPF is set to 1, or the changeover switch 31 is in the conveyor position and the conveyor F is set to 1.
Second, whether the changeover switch 32 is in the weighing position and the weighing F=1 is set, or the changeover switch 32
is the unit price and weight printing fixed position, IK=
Is WF=1 or its changeover switch 32?
is at the fixed price printing position and IK-PF=1. Next, the key reading of the contents shown in FIGS. 17 and 18 is performed between and.

First, in FIG. 17, the preset key 24
A check is made to see if is pressed, and if it is, the process moves to after completing the necessary operations.
If not, a check is made to see if the numeric key 19 has been pressed. First, regarding the state in which the numerical key 19 is pressed, preset F is checked, and if preset F=1, the process moves to after performing the preset operation, and if preset F=0, measurement F is checked. If this metric F=1, shift the unit price of S register 79 to the left, put the key contents in the lowest position of S register 79,
Put this into the upper display register 80 and display the upper display.
Turn it on and move on.

Also, if the measurement F=0, check IK-WF, if this IK-WF=1, check F1F, and if F1F=0, follow the same routine as the above-mentioned measurement F=1, and F1F= If 1 then F2F
Check, if F2F=1, move to F2F=1,
If 2F=0, shift the weight W in the S register 79 to the left, put the key contents in the bottom of the S register 79, multiply the unit price and weight to get the price P, put this in the upper display register 80, Turn on upper display
Let's move on.

Further, if IK-WF=0, as described above, IK-PF is checked, if IK-PF=0, the transition is made, and if IK-PF=1, F2F is checked.
If F2F = 1, shift to , and if F2F = 0, shift the price P in the S register 79 to the left, put the key content in the lowest price of the S register 79, put it in the upper display register 80, and display it in the upper row. ON
Let's move on.

If you go back further and find that the numeric key 19 has not been pressed, check the erase key 23, and if the erase key 23 is not pressed, proceed from the area marked (B-1) in Figure 18. When the state is reached and the erase key 23 is pressed, preset F is first checked. This preset F=1
If so, set CC-SF = 0, put 0 in the numeric register 82, put the contents of this numeric register 82 in the lower display register 81, turn on the lower display, and move on to. If preset F = 0, then the weighing F Check. If this measurement F=1, enter 0 in the unit price part of the S register 79, and input this into the upper display register 8.
Set it to 0, turn on the upper display, and move on.
At this time, if the measurement F=0, check IK-WF, and if IK-WF=1, F1F=0, F2F=
0, enter 0 into the S register 79, set the upper display register 80 to 0, display the upper display, and then proceed to the next step. Also, if IK-WF=0, check IK-PF, and if this is 0, shift to IK=PF
If =1, F1F=0, F2F=0, S register 7
The price portion of 9 is set to 0 and is placed in the upper display register 80, and the process proceeds after displaying the upper display.

Next, preset key 24, number key 19,
When none of the erase keys 23 are pressed, the state shifts from point (B-1) to the state shown in FIG. 18. First, a check is made to see if the execution key 20 has been pressed. When the execution key 20 is pressed, the preset F is checked, and when the preset F=1, the necessary work is performed and then the APF check, which will be described later, is performed. Also, if the preset F=0, check IK-WF, and if this IK-WF, check F1F,
If F=0, set F1F=1 and enter the APF check state, which will be described later.If F1F=1, check F2F, and if F2F=0, set APF to F2F=1.
The check state is entered, and if F2F=1, the state shifts to F2F. Furthermore, if IK−WF=0, then IK−
Checks PF, moves to IK-PF=0, and checks F2F if IK-PF=1.
If F2F=1, move to F1, if F2F=0
With F=1 and F2F=1, the APF is checked.

Then, the APF is checked, and if APF = 0, then the operation moves on, and if APF = 1, the operator F is checked, and if this is 0, the operation moves on, and if it is 1, the metering F is checked. If weighing F=1 and preset count up F=1, shift to weighing F=
0 and when F2F=0, it also shifts to, and the measurement F=
0, when F2F=1, preset count up When F=0, check V ₁ SF, and set V ₁ SF=
If it is 1, start the V ₁ timer, and if V ₁ SF = 0, jump this V ₁ timer start and start conveyor V ₁ 1, conveyor V ₂ 2, conveyor V ₃ 3, and set the intermittent timer to 0. do.

Next, when the execution key 20 is also not pressed, check the manual issue key (not shown) and confirm that it is
If it is YES and it is in the manual issue state, the corresponding work is performed and then the process moves on. If it is not manual issue, the operation/stop key 28 is checked. If this button is not pressed, the process will proceed to the next step, which is not shown, and if it is pressed, an APF check will be performed. If APF = 0, proceed to the necessary operations, and if APF = 1, check for Operator F. If this operator F=1, then the operator F=
0, turn off the operation lamp 47, and turn off the conveyor V _1.

Move to. Also, when APF=1, operate F=
If it is 0, check F2F and set F2F=0.
If it moves to F2F=1, the operation lamp 47
Turn ON, start conveyor V ₁ 1, conveyor V ₂ 2, conveyor V ₃ 3, and operate F=1.
, and then set the intermittent timer to 0.

In this way, the key reading and associated operations shown in FIGS. 17 and 18 are performed between and in FIG. 16, and subsequent operations are performed as follows. First, a check is made to see if the intermittent timer has timed up, and if it has not timed up, +1, and if it has timed up, conveyor V ₂ 2 and conveyor V ₃ 3
and stop. In other words, the intermittent timer counts the number of times the program cycles.
Each time the program is run, it is incremented by 1, and the number of cycles for about 30 seconds is used as the time-up timing. Therefore, there is no disturbance in the program when time-up occurs, and moreover, it is reset when the _V1 sensor 7 detects a product. Then,
V ₁ SF, V ₁ TF, V ₂ SF, V ₃ S ₁ F, and V ₃ S ₂ F are checked in sequence, and if all of these are 0, the operations from checking ACLF to starting load cell SL4, which will be described later, are completed. done, and if any one stands it will be jumped. And ACLF

Enter the data into the ZT register 84 and check the measurement F. In addition, the aforementioned Print Ready F-
If 2 = 1, the above-mentioned routine for auto-zero processing will be jumped and the weighing F will be checked, and if weighing F = 1, the weight will be calculated from the weight count register -386 and the calculation xW = P will be performed. and display it to reach the point. From this point, check print ready F-2 again, and if it is 0, return to print ready F-2.
If 2=1, print command F is set and print ready F-2 is set to 0 to reach the point.

Also, go back and display data F-2=
If it is 0, check print command F,
If this print command F=1, it will move to a point,
If the print command F=0, check the measurement F, return to the measurement F=1, check the print ready F-2 with the measurement F=0, return to the print ready F-2=0, and return to the print ready. F-
When 2=1, it moves to a point.

However, from the point, check V ₃ S ₁ F,
If V ₃ S ₁ F = 0, return to , and if V ₃ S ₁ F = 1, set print command F to 0 and check double stroke F. When this two-step printing F=0, that is, one-step printing, printing is performed and label feeding is performed, but when two-step printing F=1, that is, two-step printing, the _V1 start timer is started and the first step is started. , perform a small feed of the printing line spacing, print the second row, reset the INT V ₃ S, and feed the label. Next, check the double stroke again, and when the double stroke F=0, V ₃ S ₂ F=
1, set V ₃ S ₁ F=0, reset INT V ₃ S, and return to. Also, when double hit = 1,
Check V ₃ S ₂ F, and if V ₃ S ₂ F=0, set it to 1
and return to V ₃ S ₁ F=0. and,

Effects of the Invention As described above, the present invention detects a product by a sensor on the carry-in conveyor and then stops the weighing conveyor and the pasting conveyor if a new product is not supplied within a predetermined time set by an intermittent timer. When a new product is supplied, the weighing conveyor and pasting conveyor are put into operation.
When product supply is interrupted, only the carry-in conveyor can be operated and the weighing conveyor and pasting conveyor can be stopped, thereby reducing power consumption and extending the life of the device. This has effects such as less noise generation.
