Description

[Detailed description of the invention] The present invention is a labeling device that sequentially prints the required data of the products on the product transportation path on the label, automatically affixes the labels to the products, and sequentially adds the data using the tally memory. This invention relates to an improvement in the tally memory of a label pasting device.

Conventionally, in a label pasting device with tally memory, the label printer performs a memory addition operation on the tally memory every time the printing operation is started, regardless of the product at the label sticking position or the presence or absence of the issued label, and calculates the total weight, tally price, etc. for each item. The total number was memorized.

However, in the case of the above-mentioned conventional device, if a product stagnates or is missing on the transport path and the specified product is not conveyed to the labeling position, or if the issued label is not fed out properly in the label printer, the issued label is not placed at the specified position. Even if there is no data, a memory addition operation is performed in the tally memory with the printing operation, causing a problem in which unnecessary data is stored. Therefore, operations such as checking the unnecessary data and correcting the contents are performed later, and the tally is not completed. Memory had to be corrected, and checking for unnecessary data was also difficult, significantly reducing work efficiency.

In view of the conventional circumstances, this invention eliminates the conventional problems and prohibits the memory addition operation of unnecessary data.
The aim is to provide a label pasting device with excellent accuracy and workability, and a label detector is installed near the label printer to detect the presence or absence of an issued label, and a product detector is installed to detect the presence or absence of a product at a predetermined position. , the presence of the product and the issued label is detected by both detectors, and the output detection signal is added to the total memory.

The label printer described above is installed on a product transport path, which is a path for automatically transporting packaged or unpackaged products, and is also comprised of a belt conveyor or the like.

The transfer path may be an exit path of a packaging machine that automatically wraps products with stretch film or the like, or a path continuous thereto. In other words, the label printer may be used alone or may be assembled together with an electronic scale into an automatic product packaging machine.

An embodiment of the present invention will be described with reference to the drawings in the case of a price tag packaging machine in which a label pasting device is assembled into an automatic packaging machine.

The pricing packaging machine includes a weighing section A, a packaging section B, a label printer C, a product detector 2, an input path D that transports the product a to the packaging section B, and a packaged product from the packaging section B.
A' is composed of a carry-out path E, and belt conveyors are used for the carry-in and carry-out paths D and E, and a label printer C is provided above the carry-out 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 weighing completion signal, a weighing stability signal, a charge calculation end signal, etc. It is becoming more and more like this.

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.

The label printer C is composed of an input device C ₁ , a control mechanism C ₂ , a printing device 3, a label applicator 4, a label detector 1, and a tally memory C ₃ .

Input device C ₁ inputs the required data of product a, such as product name, product code, unit price, processing date, effective date, tare weight, and barcode data, by operating various operation keys such as the numeric keypad and clear key. etc. is input to the control mechanism _C2 in a predetermined signal form, and is installed near the weighing section A.

The control mechanism C ₂ includes a storage unit C ₄ that temporarily stores required data such as weight data, price, and the product name until printing, and a printing device 3 according to an input signal.
and a control unit C ₅ that operates the label applicator 4 in a predetermined configuration, and an arithmetic processing unit C ₆ that receives input signals from the weighing unit A and the input device C ₁ and processes the input signals to calculate a price. configured.

The printing unit 3 prints a label mount 6 on which labels 5 are releasably pasted at regular intervals on a roll 7.
The necessary data sent from the control mechanism C ₂ is printed on the label 5 by the print head, and the label mount 6 is fed out from the dispenser 7.
When reversing the label 5, the label 5 is peeled off from the label mount 6 and automatically fed out onto the lower surface of the label applicator 4.

The label applicator 4 is provided near the dispenser 7, and has an intake hole on its lower surface through which air is constantly taken in by a vacuum of a fan (not shown), and also has an ejection hole through which air is ejected with a force greater than the suction force. The label applicator 4 has a nozzle 8 which attracts and holds the label 5 peeled off by the dispenser 7 on the lower surface of the label applicator 4, and blows air downward from the nozzle 8 in accordance with the applicator command transmitted from the control mechanism _C2 . Paste it on packaged product a′.

The label detector 1 controls the memory addition command of the control mechanism C _{2 together with the product detector 2 described later, and the control mechanism C 2 performs} the memory addition based on the detection signals P ₁ and P ₂ of both detectors 1 and 2. Issue a command.

The label detector 1 is installed in the vicinity of the nozzle 8, and optically detects the presence or absence of the issued label 5 held by the label applicator 4 by suction, and outputs a detection signal P ₁ when detecting the presence of the label 5. The control mechanism C ₂
to be sent to.

The total memory C ₃ sequentially adds and stores data such as the price or weight of each product a stored in the storage unit C ₄ in response to a memory addition command Q sent from the control mechanism C ₂ . The total number of packaged products a' to which labels 5 are attached is stored based on the number of times.

The product detector 2 detects the presence or absence of a packaged product a' that has been transferred on the carry-out path E to just below the label applicator 4, and outputs a detection signal P when the product a' is present. ₂ to the control mechanism C ₂ .

The product detector 2 may optionally be a mechanical switch or a photoelectric switch consisting of a light emitter 2' and a light receiver 2'' as shown in FIGS. The presence or absence of product a′ within the range may also be detected.

Therefore, the product detector 2 and the label detector 1 are
Packaged product a′ and issued label 5 at predetermined position
detects the presence or absence of the product a' and outputs detection signals P ₁ and P ₂ when the label 5 is present, and by inputting both detection signals P ₁ and P ₂ , the control unit of the control mechanism C ₂
Memory addition command Q is output from C ₅ , and the corresponding product
Add the required data of a′ to the total memory _C3 .

Also, the detection signal from one or both of detectors 1 and 2
When P ₁ and P ₂ are not output, the control mechanism C ₂ does not output the memory addition command Q, so no memory addition operation is performed.

In addition, when the control mechanism _C2 does not output the memory addition command Q, it operates a warning means such as a warning buzzer or a lamp so that the operator can check the abnormal state, or the label printer C
is also optional.

In addition, in the above embodiment, the total memory C ₃
is provided separately from the control mechanism _C2 , but it may also be provided in the control mechanism _C2 , specifically in the storage section _C4 .

The present invention provides a label pasting device equipped with a tally memory as described above, which is equipped with a product detector and a label detector for detecting the presence or absence of products and issued labels, and uses the detection signals of both detectors to store the required number of products in the tally memory. Since the data is added to the memory, unnecessary product data is not stored in the tally memory, and the data in the tally memory is accurate, making it possible to create a highly accurate labeling device. This eliminates the need for confirmation work, etc., and enables efficient labeling work.

Thus, the intended purpose can be achieved.
