Abstract

PURPOSE:To eliminate the need to discharge remaining articles and to simplify associated operation such as proceeding to a next articles process by setting and storing the number of labels to be issued previously, counting the number of times of labeling every time sticking operation is performed, and making an advance notice for the end by an alarm when the counted value reaches a specific difference from the set value. CONSTITUTION:The quantity of labels to be issued is preset as a set value in a preset register 34 prior to packing, weighing, and pricing operation. Further, when operation for packing an article, etc., is started, a counter 38 counts up every time labeling and sticking operation ends. The difference between the counted value and set value is calculated by an arithmetic control means 23. When the difference between both calculated values coincides with the quantity of articles which can be present between a weighing conveyor and an elevator, the arithmetic control means 23 drives the alarm 42 to make a previous notice for the end of the labeling. Consequently, an operator does not insert any following article and only a set number of articles are carried in a system and processed as specified; and an advance to the next process is made immediately after the end.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to automatic packaging in which an item is packaged, the weight of the item is measured, and a label is printed with information such as the unit price, weight, price, etc. of the item and is affixed thereto. This relates to a weight value marking machine.

BACKGROUND OF THE INVENTION In recent years, with the development of the distribution industry, there has been an increase in demand for systems that package, weigh, and price items, that is, automatic packaging, weighing, and pricing machines, and improvements in their operability and functionality have been required. There is.

In general, in this type of device, the weighing machine calls out the product number corresponding to the item, and the unit price and number of bells issued (
A set number of labels is preset in advance, and the system is configured so that the operation of the system ends when the set number of labels has been issued.

Problems to be Solved by the Invention However, when items are continuously loaded into a packaging machine, even if the issuance and pasting operations for the preset number of labels have been performed, the inside of the packaging machine and the weighing Subsequent items will remain on the conveyor.

These items exceed the set value and do not require labeling. Therefore, the remaining items are discharged by operating only the conveyor, etc. without operating the system in an idling manner, ie, without performing weighing, pricing, etc. operations. If such a method is used, it is inconvenient that when the next item is to be weighed and priced, it is necessary to wait for the previous item to be discharged. After all, in the case of the conventional method, since it is not known to what extent each operation has progressed with respect to the set value, extra items are also inserted, resulting in such inconvenience.

Means for solving the problem The items inserted through the insertion slot are automatically wrapped by a packaging machine equipped with an elevator, and the items carried in from this packaging machine are weighed by the weighing section on a weighing conveyor. Afterwards, the item is sent from the weighing conveyor onto a pasting conveyor, and on this pasting conveyor, a label on which data based on the weighing result is printed is issued by a pasting printer, affixed to the goods, and discharged in an automatic packaging weighing and value labeling machine. ,
First, a preset register is provided in which the number of labels to be issued is recorded in advance as a set value, and a counter is provided to count the number of times each label is issued or pasted to an item on the pasting conveyor. Then, the difference between the set value and the counted value of the counter is calculated, and when this difference reaches the number of items that are simultaneously present between the weighing conveyor and the elevator, an alarm is activated to notify the end of label issuance, and the count value is calculated. A calculation control means is provided to stop the alarm when the numerical value reaches a set value.

Prior to the packaging, weighing, and pricing operations, the number of labels to be issued is preset as a set value in a preset register. On the other hand, once an operation such as wrapping an item is started, a counter counts the number of times each label issuance/affixing operation is completed. Then, the difference between this count value and the set value is calculated by the calculation control means.

When the calculated difference between the two coincides with the number of items that can be present between the weighing conveyor and the elevator at the same time, the calculation control means activates an alarm to notify the end of label issuance in advance. In other words, after this, when the weighing and pricing operations for the items that have already been inserted and exist between the weighing conveyor and elevator are performed, the processing for the initial set value will be completed, and the next step will be based on this advance notice. The worker will be reminded that it is unnecessary to insert the following item, and the operator will not insert the subsequent item. As a result, only the items corresponding to the set value are brought into the system and subjected to predetermined processing, and after completion of the processing, processing can immediately proceed to the next item.

Example An embodiment of the present invention will be described based on the drawings.

First, as shown in FIG. 2, a packaging machine 1 and a weighing machine 2 are connected to each other. The packaging machine 1 has an insertion port 3 configured as a carry-in conveyor on its front side, and is provided with an elevator 4 for film packaging and a film peat section 5 configured as a beat conveyor inside. That is, the article set on the insertion slot 3 is conveyed into the elevator 4, a packaging film cut to a predetermined length is sent out onto the article on the way, and the article is raised by the elevator 4 against this film. The product is packaged by the fusion action of the film heat 14i15.

In this packaging machine 1, an operation panel 6 is provided above the insertion slot 3, and the operation panel 6 is provided with various operation keys 7a and a display section 7b.

Next, in the weighing machine 2, first, the weighing conveyor 8 located in front of the film heating section 5 of the packaging machine 1 is moved.
A measuring section 9 having a measuring section 9 is provided. This weighing section 9 weighs the items transferred onto the weighing conveyor 8.
A metering arm 10 is provided on the negative side. A pasting conveyor 1 is provided on the opposite side of the weighing arm 10 via a dummy conveyor 11 that is inclined with respect to the conveying direction.
2 are installed in succession. The weighing arm 10 is used to push and transfer weighed items from the weighing conveyor 8 onto the dummy conveyor 11.

Further, the dummy conveyor 11 is for conveying the article onto the pasting conveyor 12 along the conveyance guide 13 as shown in FIG. A pasting printer 14 having a built-in printer is provided for the pasting conveyor 12. This pasting printer 14 has a label issuing port 15.
A pasting device 16, such as a pasting arm, is provided for automatically pasting the issued label onto the item. Further, in front of the pasting conveyor 12, a discharge conveyor 17 is provided in an inclined state for discharging items with labels pasted thereon. Then, the pasting conveyor 1
The second part is provided with a discharge arm 18 for pushing and transferring pasted items onto the discharge conveyor 17.

In FIG. 3, thick line arrows indicate the transport direction of the conveyor, and thin line arrows indicate the flow of the product [9].

Here, as a control system of such a system, as shown in FIG.
), the conveyor control section 21, and the packaging machine, and are connected to each other by CPUs 22, 23, and 24, respectively. Here, the CP of the label printer section 2o is
For U22, the printer section 25, the measuring section 9 and the key
A display section 26 and a program memory section 27 are connected. Here, the printer section 25 is connected to a stepping motor 28.
, a head drive controller 29 , and a printer controller 30 . In addition, the measuring section 9 is connected to the load cell 31 and the A/
It consists of a D converter 32. Further, the key/display section 26 includes various operation keys 7a, a display section 7b, and a key/display section controller 33.

Furthermore, the program memory section 27 is a ROM/RAM
This is due to B2, and this ROM/RAM 3
A preset memory is provided in part of 4.

Next, the CPU 23 of the conveyor control unit 21 serves as an arithmetic control means, and the CPU 23 is provided with an AC motor control circuit 35 for the conveyor, a stepping motor control circuit 36 for the pasting arm, and a photosensor type sensor 37. ROM for counter 38 and program memory section
/ RAM 39 is connected. Here, the sensor 37 is a transmission type optical sensor provided on the discharge side of the pasting conveyor 12, as shown in FIG.
This is to detect the discharge from the affixing conveyor 2 for items 19 for which labels have already been issued and affixed. The counter 38 uses the detection signal from the sensor 37 to sequentially count up the number of label issuing and pasting operations.

Furthermore, for the CPU 24 of the packaging machine 1, there is an AC for the drive section.
A motor 40, a photosensor type sensor 41, and an alarm device 42 that emits an alarm sound are connected. Here, the sensor 41 has the same configuration as the sensor 37, and is arranged as shown in FIG. 3, for example.

In such a configuration, the operation keys 7a of the operation panel 6
Call up the product number of the target item and enter the unit price and set quantity (
The number of labels to be issued) is set in advance in the preset register in the P, OM/RA Ni 34 as the setting value N for the weighing value marking machine 2. This makes it possible to issue a label. Then, when the article 19 is placed in the insertion port 3 of the packaging machine 1, the article 19 is conveyed to the elevator 4.

Then, the next item 19 is placed in the insertion slot 3. The previously inserted item 19 is wrapped and reaches the film heating section 5, and the next item 19 is fed into the elevator 4. Furthermore, when the next item 19 is placed in the insertion slot 3, the first item 19 is transferred onto the weighing conveyor 8, the second item 19 reaches the film heating section 5, and the item 19 located in the insertion slot 3 is transferred. is transferred to elevator 4.

In this way, the two articles 19 are present inside the packaging machine 1, and the articles 19 are sequentially fed.

Next, the article 19 discharged from the packaging machine 1 is moved onto the weighing conveyor 8, and its weight is measured by the meter M section 9.

When this weighing is completed, the item 19 is transferred onto the dummy conveyor 11 by the weighing arm 10, and when this item 19 reaches the pasting conveyor 12, the pasting printer 14 issues a label in synchronization with the movement of the item 19, A label is pasted onto the item 19 by the pasting device 16 .

Data corresponding to the weight of the item 19 is printed on this label. After the label is pasted in this manner, the item 19 is transferred to the discharge conveyor 17 by the discharge arm 18, and packaging weighing is completed.

Here, when a plurality of items 19 are processed continuously during such packaging, weighing, and pricing operations, a maximum of five items 19a to 19e may exist in the system at the same time, as shown in FIG. In other words, an item 19e exists in the elevator 4, an item 19d exists in the film heat section 5, an item 19c exists on the weighing conveyor 8, and an item 19c exists on the pasting conveyor 1.
2, there may be an item 19b, and on the discharge conveyor 17 an item 19a.

Therefore, in this embodiment, the counter 38 counts the number of times each label is issued and pasted on the item lid on the pasting conveyor 12. As described above, this count is incremented every time the sensor 37 detects the discharge of the article 19 from the pasting conveyor 12.

If the count value of this counter 38 is n, then every time this counter 38 counts up, the preset value N
The CPU 23 calculates the difference between the count value n and the count value n. When this difference becomes 3, that is, the count value n is n-N-3
In this case, the CPU 23 sends a signal to the CPIJ 24 side, which drives the alarm 42 to generate an alarm sound forewarning that label issuance will soon end. This notifies the operator that insertion of the item 19 into the insertion slot 3 should be stopped. Here, the number three means weighing conveyor 8.
・This is the number of items 19 that can exist between the two elevators 4 at the same time, and in this example, three items 19 as shown in FIG.
This is because c, 19 d, and 19 e may exist. In this way, the item 1 on the pasting conveyor 12 is
When 9b becomes n=N-3rd, the item 19c on the weighing conveyor 8 to be priced next is the N-2nd item, the item 1.9d on the film heat section S is the N-1st item, and the elevator This is because the item 19e above 4 is the Nth item, and if the remaining items such as weighing and pasting are performed on the items currently in the system, the processing for the set value N will be completed. In this way, even if the alarm 42 is activated and a warning sound is emitted to notify the end of the label, when the number of times the label has been issued and pasted, that is, the counted value n by the counter 38 reaches n=N-3, the packaging/weighing・The pricing operation continues, and the items 19c and 19d that were present on the weighing conveyor 8, film heat section 5, and elevator 4 at the time when n=N-3
, 19 e are sequentially processed. and,
When the process is completed and the count value n reaches the set value N, and n=N, the price for the last item 9e will be changed to item 19.
Since the series of processes related to the above is completed, the alarm device 42 is stopped and the warning sound for notifying the end is also stopped.

This informs the user that the next item is ready for processing.

As described above, according to this embodiment, the count value n of the counter 38 that counts the number of times that labels have been issued and pasted is n=N-3 (this embodiment ), and when the difference between the two reaches a predetermined value, the alarm device 42 is activated to issue a notice of termination notice (not limited to an alarm sound, for example, a proactive notification method may be used). As a result, it is possible to warn the worker that the next item is prohibited from being brought in, so it is assumed that there will be no extra items in the system by the time all the items for the set value N have been processed. Become. Therefore, there is no need for the work of discharging such extra items or the waiting time before moving on to processing the next item. Furthermore, since carrying in excess items is prevented, unnecessary packaging is eliminated and packaging film is saved. Furthermore, since there is no article in the film heat section 5 etc. at the end of the processing for the set value N,
It is also possible to prevent thermal deterioration of the product.

Effects of the Invention As described above, the present invention stores the number of labels to be issued as a preset value in a preset register, and
A counter counts the number of times each label is issued and pasted on the pasting conveyor, and when the counted value reaches a predetermined difference from the set value, an alarm is activated to notify the end notice. Since this notification is stopped when all items are completed, it is possible to warn the operator not to insert more items than the set value, and therefore, the packaging, weighing, and pricing are completed within the system. Therefore, there is no need to dispose of the remaining items, which simplifies the operator's associated work such as moving on to the next item.
