Description

[Detailed description of the invention] The present invention is a value packaging machine.More specifically, the invention includes a weighing section for weighing the product, a packaging section for packaging the product, sequentially printing required data of the product on a label, and attaching the label to the packaged product. The present invention relates to an improvement in the tally memory of a label printer in a label packaging machine comprising a label printer equipped with a printing and pasting device for pasting and a tally memory for adding up the data.

Conventionally, in the price tag packaging machine mentioned above, the label printer prints the required data of the product on the label regardless of the presence or absence of the product at the label affixing position, and at the same time stores the data in the tabulation memory of the label printer according to the content of the data, such as weight, price, etc. The number of products packaged was added up.

Therefore, even if there is some kind of abnormality in the packaging machine, such as stagnation or missing products, and there is no designated product at the label attachment position, a label will be issued and its contents will be added to the tally memory, so the extra amount will be added later. It is necessary to check the data and perform operations such as correcting the contents to correct the total memory, and this checking work is also difficult and significantly reduces work efficiency.

In view of the conventional drawbacks as described above, the present invention aims to provide a price tagging machine with excellent workability by eliminating the addition of extra data in the tally memory of a label printer. A detector for detecting the presence or absence of a product is provided at a fixed position near a label printer equipped with a printing and pasting device that prints on a label and affixes the label to the packaged product, and a tally memory that adds up the data; The apparatus is characterized in that it confirms the presence of a product at a predetermined position, issues a detection signal, and adds the required data to a tally memory.

Embodiments of the present invention will be described below based on the drawings.

As shown in Fig. 1, the pricing packaging machine has a weighing section A, a packaging section B, a label printer C, a detector 1, a carry-in path D that transports the product a to the packaging section B, and a packaged product a' from the packaging section B. It consists of a carry-out path E for carrying out, and a belt conveyor is used for the carry-in path D and the carry-out path E.
The label printer C is provided on the delivery path E, and the detector 1 is provided below the label printer C on the side of the delivery path E.

Weighing unit A weighs product a placed on a weighing plate, converts the weight into a predetermined electrical signal, and inputs the signal to label printer C.

The product a weighed in the weighing section A is placed on the carry-in path D and transferred to the packaging section B, either manually or by mechanical means that operates in conjunction with a measurement completion signal, that is, a weighing stability signal, or a charge calculation end signal. It's becoming like that.

The packaging section B automatically wraps the product a with a wrapping material such as a stretch film, and carries out the wrapped product a' to a carry-out path E.

As shown in FIG. 2, the label printer C is composed of an input device C ₁ , a control mechanism C ₂ , a tally memory C ₃ , a printing device 2 and a label pasting device 3, and the input device C ₁ is integrated with the label printer C. Either a built-in arrangement structure or a structure installed near the above-mentioned weighing section A as shown in the figure may be used.

The control mechanism C ₂ is a storage unit 4 that temporarily stores weighing data, weight, amount of the same bag, price, manufacturing date and time, expiration date, barcode data, etc. until printing, and prints according to input signals. It is composed of a control section 5 that operates the device 2 and the pasting device 3 in a predetermined manner at a timely manner, and an arithmetic processing section 6 that processes input signals from the weighing section A and the input device C ₁ to calculate prices and the like.

In response to the memory addition command from the control mechanism _C2 , the totalization memory _C3 cumulatively adds and stores the price or weight from the data of products a and a' stored in the storage unit 4, and also stores the total value. The number of packaged products a' is stored based on the number of times.

The printing device 2 connects the control mechanism C ₂ to the labels 7 that are pasted on a mount at regular intervals and transported intermittently.
The data of products a and a' stored in the storage section 4 of is printed in a timely manner according to a print command.

The label pasting device 3 is installed so as to be located directly above the delivery path E, and the label 7 printed by the printing device 2 and fed out onto the bottom surface is attached to the corresponding packaged product.
When a' is transferred directly below on the unloading path E, it is affixed by spraying.

The detector 1 may be a mechanical switch or a photoelectric switch such as a phototube, as shown in FIGS. However, it is optional to further detect the presence or absence of product a' within a certain range using a plurality of detectors 1.

The detector 1 is installed at the position where the label is attached to the product a', detects the presence or absence of the product a', and sends a detection signal to the control mechanism _C2 only when the product a' is present. Make C ₂ issue a memory addition command.

In the above embodiment, if the product a' is not in the label pasting position, the printing device 2 and the pasting device 3 of the label printer C can either perform the label printing pasting process or prohibit that process. Optional.

In the above case, it is preferable to issue a warning with a buzzer or lamp.

In the present invention, as mentioned above, in a price tag packaging machine having a tally memory, if the product is not in the labeling position, the data of the corresponding product is not added to the tally memory by the function of the detector.
It is possible to prevent unnecessary product data from being stored in the tally memory, the tally data of the actual product matches the data in the tally memory, and there is no need for operations such as correction operations or confirmation of corrections, which improves work efficiency. A highly accurate price tag packaging machine can be achieved.

Thus, the intended purpose can be achieved.
