Description

[Detailed description of the invention] Technical field of invention The present invention relates to an automatic packaging weighing and pricing machine.

Technical background of the invention and its problems In recent years, with the development of the distribution industry, the demand for systems that package, weigh, and price items has increased, and automatic packaging machines and automatic weighing and pricing machines have become more popular. There is an automatic packaging weighing and pricing machine that integrates the following. However, in reality, the packaged items need to be weighed and priced, so they are simply connected structurally in terms of layout, and they interfere with the flow of items on the conveyor. It would be better if it were not present. In other words, the automatic packaging machine and the automatic weighing and value labeling machine simply operate in different ways.

Therefore, the settings of an automatic packaging machine, such as the cut length of the packaging film, are generally set such that the packaging machine cuts a roll of packaging film to a predetermined length, feeds it onto the product, and raises the product against the film. (Since the peripheral edge of the film is bent under the product, it is necessary to set the film cut length according to the product.) The operation mode of the packaging machine can be changed using the switches on the operation panel of the automatic packaging machine. Settings, such as unit price and date, are made using the automatic weighing machine.

The operating mode is determined by operating switches on the operation panel of the automatic weighing machine.

As a result, in order to set the film cut length that matches the product, the operator must memorize that value, set the product number on the automatic weighing and pricing machine, and then set the film cut length on the automatic packaging machine. This is inconvenient because you have to go through the following steps.

Purpose of invention The present invention was made in view of these points.

An object of the present invention is to obtain an automatic packaging H4 quantity pricing machine capable of improving operability by controlling the film cut length in the automatic packaging machine by operating the automatic weighing and pricing machine side.

Summary of the Invention The present invention provides for setting the cut length of packaging film of an automatic packaging machine using this PLU when setting PLU data of an automatic weighing machine.
There is a structure in which the film cut length is automatically set when the PLU is operated by setting it in the data, thereby eliminating the need for individual operations and improving operability.

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

First, FIG. 1 schematically shows the external appearance of an automatic packaging weighing and pricing machine, which is basically an automatic packaging machine 1 and an automatic weighing and pricing machine 2 integrated together. As a result, first, an item set on the packaging conveyor 3 of the automatic packaging machine 1 is conveyed through the packaging machine, and a packaging film cut to a predetermined length is sent out onto the item along the way. The goods are lifted up and packed. Then, the package is transferred to the automatic weighing machine 2 according to the packaging conveyor 3 (more specifically, it is conveyed by the conveyor 3a or the heat conveyor 3b). First, a weighing conveyor 4 is arranged in front of the packaging conveyor 3, and the items transferred onto this weighing conveyor 4 are shaved. When the weighing is completed, the weighing arm 5 pushes the articles out to the side and transfers them onto the conveyor 6. This conveyor 6 is a conveyor guide 7
The items are sent onto the pasting conveyor 8 along the following lines.

A label issued by a label printer 9 is pasted to the item sent onto a pasting conveyor 8 by the operation of a pasting arm 1o. The article is then sent out by the discharge arm 11 and discharged to the front side by the discharge roller controllers 12 and 13. In FIG. 2, thick arrows indicate the conveyance direction of the conveyor, and thin arrows indicate the flow of goods. 8 14 is an operating section in the automatic packaging machine 1, and 15 is an operating section in the automatic weighing and pricing machine 2. The configuration of this operation section 15 is shown in FIG.
In addition to an execution key 19, various keys 20 such as product number, key switches 21 and 22, an operation switch 23 for starting/stopping, and a business changeover switch 24 for switching packaging mode with measurement value, mode with measurement value, and packaging mode. A power switch 25 is provided. Further, there are provided various keys such as a sheet key 26, and a changeover switch 27 for selecting whether the film cut length is to be set by a PLU setting (automatic), which will be described later, or by the automatic packaging machine 1 side. 28 is an LED for displaying errors and the like. Although not particularly shown in the drawings, the operating section 14 is provided with a dial and the like for setting the film cut length.

These systems are controlled by a system controller 30 as shown in FIG. 4, and the system controller 30, automatic packaging machine 1, and automatic weighing and value marking machine 2 each have ROMs 31, 32, 33, RAMs 34, 35 . It has a CPU 37.38.39 to which 36 is connected, and is connected via I10 boats 40, 41, 42 and photocouplers 43.44. Weighing conveyor 4 on I10 boat 40
, an AC motor control circuit 45 for an AC motor for the conveyor 6, the pasting conveyor 8, the discharge arm 11, etc., a pulse motor control circuit 46 for a pulse motor for the pasting arm 10, and switches 47 are connected. Also, I10
A motor control circuit 48 is connected to the boat 41 .

On the other hand, in the automatic weighing value marking machine 2, the weighing output from the load cell 49 is inputted to the I10 port 42 via the analog-digital converter 50, and
9 is a printer controller 51 for the label printer 9. Display tube 52. A display/key controller 54 for the keys 53 is connected.

In such a configuration, first, the main flow on the system controller 30 side is shown in FIG.

After initial set, memory, and I10 initial reset,
It is determined whether the operation switch 23 is ONL, and if it is OFF, the "measurement complete" signal is reset, but if it is ON, the discharge operation is performed. This discharge operation is performed when the power switch is ON.
and the initial discharge operation when switching from stop to operation, which is processed according to the flowchart in FIG.

First, if the ejection flag=1 and the ejection arm 11 is not at the home position, the ejection arm 11 is reversely driven and returned to the home position. If it is at the home position, it is stopped. A photo sensor (ps) for detecting the article is installed at the entrance of the pasting conveyor 8, but if this photo sensor is not ON, the transport conveyor 6 and the pasting conveyor 8 will rotate in the normal direction, and the pasting conveyor will not be able to carry the goods. 8. On the other hand, when the article is transferred onto the pasting conveyor 8 and the entrance photo sensor is turned on, the transport conveyor 6 and the pasting conveyor 8 are stopped to apply the label, and the discharge arm 11 is driven forward to discharge the article. Then, timer 1 processing is performed. Here, what is timer l processing?

This refers to the time required for the ejection arm 11 to complete ejection of the article from its home position. After the timer 1 processing, the discharge arm 11 stops, returns to the home position by reverse drive, and stops at the time of returning.

Next, the transport conveyor 6 and the pasting conveyor 8 are rotated in the normal direction. If the entrance sensor of the pasting conveyor 8 is OFF, the forward rotation of the conveyor 6.8 continues until 500 m5 has passed and then stops. On the other hand, if an item is present and the pasting conveyor sensor is ON, the item is gone and both conveyors 6.8 are stopped after waiting until 500 IIls have elapsed.

Then, at the same time as described above, the ejection operation of the ejection arm 11 is performed. In any case, if the items on the weighing conveyor 4 have been completely discharged at this time, the process ends. On the other hand, if the discharge of the items from the weighing conveyor 4 is not completed, the discharge flag is set to O.

If the measuring arm 5 is not at the home position, it is returned to the home position by reverse drive, and if it is at the home position, it is stopped as it is. Here, weighing conveyor 4
Looms rotates forward and the items are brought together. After that, the transport conveyor 6 rotates forward and the i1 view arm 5
is driven forward and the items are transferred from the weighing conveyor 4 to the transport conveyor 6.
It is transferred to and discharged. Here, the timer 2 refers to processing the time required from the home position of the weighing arm 5 to the completion of discharging the article. Then, when the weighing arm 5 returns to the home position, it stops, the discharge onto the weighing conveyor 4 is completed, and the transport conveyor 6 and pasting conveyor 8 start rotating normally.

The reason for performing such an initial discharge operation is as follows. That is, pieces of meat due to pack leakage, film fragments due to packaging mistakes, etc. tend to remain on the conveyor, and if this is on the weighing conveyor 4, it will cause a mistake in weighing the product, and no matter which conveyor is used, the product will not be weighed properly. This will hinder smooth conveyance.

Therefore, in this embodiment, as described above, the power switch 2
Immediately after the conveyor belt 5 is loaded or when the machine is switched from a stopped state to an operating state, a discharge operation is always performed to clean the top of the conveyor.

After the discharge operation is completed, a mode check is performed.

Here, there are three modes: packaging mode with measurement value, mode with measurement value, and packaging mode.
4 is selected. Now, if you are in packaging measurement value mode, check to see if the cut length of the film is set.

That is, when the PLU set signal is at H level, the selector switch 2
Check if 7 is set to automatic. If it is automatic, P
When setting the LU, the film cut length has already been set, and the film cut length is output to the automatic packaging machine 1 side. Then, the operation mode "4" is output to the automatic packaging machine 1 side. Here, it is assumed that the operation mode for sending to the automatic packaging machine 1 side is set as shown in the table below. On the other hand, if the PLU set signal is not at H level or the changeover switch 27 is not on the "auto" side, the changeover switch 27
At this time, the LED on the packaging machine side lights up, and the operation mode "3" is output to the automatic packaging machine 1 side. Furthermore, in the weighing value mode, the automatic packaging machine 1 is not involved;
Operation mode "2" is output to the automatic packaging machine 1.

If it is the packaging mode, the LED on the packaging machine side lights up in the changeover switch 27, and the operation mode "3" is output to the automatic packaging machine 1 side.

Thus, it is determined whether HP ready is at H level.

In other words, whether the load cell scale is OK to accept the item, etc.
Determine whether the automatic weighing value marking machine 2 side is operable and check the HP
If the ready signal is not at H level, it is assumed that the machine is inoperable, and the "weighing complete" signal is reset, the automatic packaging machine 1 is also disabled, and each mode process is not performed. on the other hand,
If HP ready is at H level, each mode process is performed after setting the "metering complete" signal. In other words, it is determined based on the HP ready signal whether or not the automatic weighing and price tagging machine 2 is operable, and the result is sent to the automatic packaging machine 1, and the automatic weighing and price tagging machine 2 operates the automatic packaging machine 1. It controls the This is because if the automatic packaging machine 1 operates while the automatic weighing and pricing machine 2 is in an inoperable state, items will accumulate on the conveyance path.

This is because it may cause trouble. However,
According to this embodiment, the operation of the automatic packaging machine 1 is controlled by the automatic weighing and value labeling machine 2, and the automatic packaging machine 1 can operate only when the automatic weighing and value labeling machine 2 is operable, so that the above-mentioned troubles can be avoided. Does not occur.

Here, each mode process is performed according to the flowchart shown in FIG. In other words, the product is transported from the automatic packaging machine 1, weighed (label issued) and transferred to the transport conveyor 6 by the weighing arm 5.
In a series of cycles of sending upward → conveying to the pasting conveyor 8 by the conveyor 6 → pasting the label on the pasting conveyor 8 by the pasting arm 10 → discharging by the discharge arm 11, the conveyance route is determined by pasting accuracy (position) etc. Ori.

It is sent along a guide 7 provided along the route.

In this regard, according to the conventional method, the conveyor is arranged so that the goods advance diagonally toward the guide from a line parallel to the guide, but it is not possible to make the conveyor diagonally large. When considering the smooth flow of goods, there is a limit, and the goods cannot be brought to a sufficient position. Another method is to dispose the conveyor diagonally, and when the article is conveyed onto the weighing conveyor, the weighing conveyor conveys the article as close to the guide as possible for weighing. However, with this method, the position of the item is quite far from the center of the weighing conveyor, resulting in variations in the accuracy of the scale and difficulty in stabilizing the item.

Unable to measure accurately. Therefore, in this embodiment, regardless of the mode, when an item is conveyed from the automatic packaging machine 1, the item is stopped at the center position of the weighing conveyor 4 (solid line position in Figure 2) and weighed. After weighing, the separate quantity conveyor 4 is operated in Looms mode to move the goods toward the guide 7 side as shown by the dashed line in FIG. It is something that makes you In addition, in Fig. 7, 50
0m5 indicates a dummy loop. Further, the processing of label issuance completion and pasting operations in the quantity pricing mode and the packaging measurement pricing mode are processes that are performed in parallel by one interrupt process.

On the other hand, the main flow in the automatic weight value tagging machine 2 is shown in FIG. After initial setting, memory, I10 initial reset, and display scanning, it is determined whether the error flag is 1, and if it is an error, error processing is performed. Thereafter, data is read from the load cell scale, mode changeover switch is read, and key processing is performed. Regarding this key processing, a flowchart centered on setting the cut length of the film is shown in FIG. Now, if the numeric keypad is 17, the cut flag is 1
, the input data is displayed and sent to temporary storage memory.

Then, if the sheet key 26 is pressed and the cut flag is not 1, 1 is displayed after the previous setting contents are transferred from the PLU memory to the temporary storage memory, and the cut flag becomes 1. On the other hand, if the cut flag is 1, it is determined whether the cut length stored in the temporary storage memory is the specified data. Here, the cut lengths are 25, 30, 35,
40, 45°5 (1 + 55 + 60cm) is standard data; any other value will result in an error, the error flag will be set to 1, and the above-mentioned error processing will be performed. If it is in the measurement mode, the contents of the temporary storage memory are transmitted to the system controller 30 side, If fi mode is displayed, and the cutting length cera 1- is completed.

On the other hand, in setting mode, the contents of temporary memory are P
After the film is sent to the LU memory, the setting mode is displayed and the setting of the film cut length is completed.

After such key processing, normal control of the scale and printer is performed according to FIG.

Furthermore, the main flow in the automatic packaging machine 1 is shown in FIG. This automatic packaging machine 1 has a limit switch that detects the product at its entrance, ONL, and a wrapping completion signal.
It is in a standby state until the level is reached, and thereafter it is controlled by the operation mode given by the system controller 30. Now, if the operation mode is r4J, the system controller 30
Items are packed using a film cut at the length of the film cut from the side and sent to the unfolding conveyor 4 side. If the operation mode is [2j], the product only passes through the automatic packaging machine 1, and no film comes out. If the operation mode is other than "4" or "2", the product is transported from the packaging conveyor 3 and the product is cut by the film cut length set by the operation section 14 of the automatic packaging machine 1. will be packed.

In other words, according to this embodiment, the PLU of the automatic weighing value marking machine 2
The data is determined by keystrokes on the operation unit 15. At this time, the cut length of the packaging film is also entered into the PLU data and determined by the keystrokes on the operation unit 15. By the PLU operation that calls up the film cut length, the film cut length corresponding to the product number is automatically called from the PLU memory and is loaded, which simplifies operations related to the film cut length. .

Here, even if the product has the same product number, the size may differ depending on the product, and the cut length of the film may need to be changed, but the contents of the PLU memory can be changed as shown in the flowchart shown in Figure 9. You can temporarily change the film cut length without any trouble, so you can deal with it. Also,
Depending on the mode of use, it may be necessary to set the film cut length on the automatic packaging machine 1 side, but in this example, the PLU
This allows not only setting but also setting on the automatic packaging machine 1 side, and selection can be made using the changeover switch 27. Furthermore, by setting the operation mode on the automatic separate pricing machine 2 side, it is possible to control the operation on the automatic packaging machine 1 side, including the settings of the film cutter 1 to length, which further simplifies the process.

Effects of the Invention As described above, when setting the PLU data of the automatic weighing and value tagging machine, the cutting length of the packaging film of the automatic packaging machine 1 is set in the PLtJ data, and the film is automatically cut when the PLU is operated. Since the length can be set, it is possible to simplify the operation of setting the cut length of the packaging film.Also, the film cut length can be changed temporarily without changing the contents of the PLU memory, so the same product number can be changed. It is possible to deal with the case where the size of the product changes even if there is a change in the size of the product, and furthermore, it is possible to set the film cut length on the automatic packaging machine side, so it can deal with various situations.
