[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a packaging device that attaches weight values, specifically, automatically packs products after weighing them, and then affixes a label with required printing to the packaged products. The invention relates to a device for

(Prior art) As seen in Japanese Patent Application Laid-Open No. 54-123391, the method described in the publication includes a weighing conveyor installed on the product feed path side of a packaging section that automatically packages products, and weighs products one by one. A supply conveyor is installed to transfer the products onto the conveyor, a Seijin conveyor is installed to transfer the products on the weighing conveyor to the packaging section, and a label printing and pasting device is installed on the output side.

In this conventional device, a product is transferred to a weighing conveyor, weighed while passing through the conveyor, sent to the packaging department via a one-shell large conveyor, and the packaging material is automatically wrapped around the product in the packaging department. The product is generally taken out from the packaging department by a production conveyor, and the necessary data related to the product is printed on the label by a label printing and pasting device on the heater conveyor, and the label is automatically pasted on the product. It is.

(Issue 5 to be solved by the invention) In the above-mentioned conventional device, the products are weighed while they are passing through the weighing conveyor, and while the weighed products are being transferred on the large conveyor, a photoelectric switch is activated. When detected, the next product is transferred from the conveyor onto the supply conveyor.

However, in conventional equipment, the weight of the product is measured while it is passing through the weighing conveyor, so Z
It took a long time to measure the measured value, resulting in a decrease in the processing capacity of the entire device.The purpose of the present invention is to solve the above-mentioned drawbacks of the conventional device. It is.

(Means for solving the problem) A weighing device, a packaging device, and a label pasting device are provided, each device is connected by a conveyance section, and an item weighed by the weighing device is packaged by the packaging device. A label with necessary information printed on it based on the weighing data is pasted on the item using a labeling device.A weighing device attaches a label to the item using a labeling device.The weighing device weighs the item once it has stabilized after being conveyed to the weighing device, and the weighing device on the weighing device The gist of the invention is a weighing device characterized in that it comprises a starting means for starting the conveying section with a weighing stability signal outputted from a weighing stabilizing weighing device.

(Example) As shown in FIG. ) (14)
are connected by the conveyance section (3), the item A weighed by the weighing device (11) is packaged by the packaging device (12), and the unit price, weight, price, etc. of the item is labeled by the label printer (I3). The label is printed on the label pasting device (14).
At this time, the data to be printed on the label is input to the shift register (21) via the control device (2), and the shift register (21) is affixed to the item in synchronization with the transfer of the item. Shift the inside of register (21),
The label printer (13) prints the item at the timing when the content of the item and the above data match. However, when weighing items that do not require packaging, there is no need to install a packaging device (12), and when it is acceptable to print directly on packaged or non-packaged items, it is necessary to use a label pasting device. In addition, a simple printer may be used instead of the label printer (13).

Therefore, to explain in detail about Fig. 2, the numeral part (41)
directly into the buffer register (22) via the control device (2) using
The product code, product name, unit price, etc. are written in the register, and the product code, product name, unit price, etc. of the corresponding product is written in the buffer register (22) via the control device (2) according to the product code input from the register section (41). ). Further, the conveyance section (3) advances by one pitch each time the start signal Pb output from the control device (2) is input based on the scale stability signal Pc input from the weighing device (11) to the control device (2). It is designed to transport items placed on it. The shift register (21) has a data flag area (
21a), a setting data area (2l b), and a measurement data area (21c) are provided, and a data flag Da is set in the data flag area (21a) when there is data in the other two areas. When there is no flag, the flag will be lowered. In the setting data area (2lb), in addition to the unit price and available number of items, settings related to the item name and the name of the store to which the item is delivered are stored. The weighing area (21c) contains weighing data (weight, price, etc.) regarding the weight of the item transferred from the weighing device (11).
DC is stored. These three sets of data flag Da, setting data Db, and weighing data Dc are synchronized with the movement of the item on one narrowing section (3), that is, in accordance with the movement of the transport section (3). The printer (13) and the label pasting device (14) sequentially shift the shift register (21) according to the timing pulse Pa output by the sending unit (3) 18 so that the item A matches the data corresponding to the item A.
) is activated. Label printer (13)
), dot printers (
For example, use a thermal printer to print out the product name or store name in text. FIG. 3 shows the CPU as the control device (2) in this invention explained above.
20 is a flowchart when using 20. In FIG. 3, when the power is turned on, the program installed in the CPU 20 starts (Fl). Next, the number part (4
1) Using the numeric keypad, etc., enter the name of the item, the name of the item, the name of the store to be delivered to, etc. directly or in memory (5)
Read it from the buffer register (22) and set it in the buffer register (22) (F2). Next, the start button (42) is pressed to start the entire system (F3), and the weighing data DC for the first item is obtained from the frame holder U (11) when the frame holder J (11) is stabilized (F32). At the same time, when the balance stabilization signal Pc is input to the CPU 20, the start signal Pb
is input to the conveyance section (3), and when the 1-squeezing section (3) is activated, a timing pulse Pa is output, so the above-mentioned weighing data and other data are shifted by 1 in the shift register (21), and then transferred to the conveyance section. (3) transports the one-pitch item forward. When the items are weighed one after another, their weighing data is shifted (F4) and the items are also transferred.
When the item reaches the applicator (14), the shift register (2)

6), affixing the label to the item using the affixing device (14) (Fl); Then, the data flag Da related to the printed data in the shift register (21) is lowered. Note that in order to perform this pasting work, the item must be at the position of the pasting device (14), and the sensor (6) is used to detect the position. The printer (13) and pasting device (14) operate when the data flag Da in the shift register is set (F5).
1). Therefore, until the first item reaches the applicator (14), and if the item is removed during transport,
Since the detection signal Pd is not output, the printer (13) and pasting device Z (14) do not operate.

Setting data such as product name can be changed at any time using the numeric keypad of the numeric field (41), and when changes are made, the contents of the buffer register (22) are simply rewritten without interrupting the work. You can continue (F31).

The end key (43) in Fig. 2 is used when finishing the work (
When the weighing of the last item is completed, the transport unit (3) is activated so that all the items are transferred one by one even without the start signal pb, and the items are printed one by one. and finish the work.

(SuJ) The product is weighed on the weighing device and weighed when the weighing device becomes stable, which allows for highly accurate weighing, reduces weighing time, and ensures that the weighing on the weighing device is stable. Since the transport section is activated by the scale stability signal output from the device, the transport section is always activated after a stable weighing has been performed, so one narrowing section is activated during the weighing of the item, resulting in impossible or incorrect measurement. This has the advantage that weighed items can be sent to the packaging device quickly without any problems, and the overall speed of the device can be increased.
