Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a weighing, packaging, and pricing device, specifically, it automatically packages products after weighing them, and then labels the required information based on the data at the time of weighing. Along with printing,
The present invention relates to an improvement of a label printer in a device for pasting the label onto packaged products.

(Prior Art) In this type of weighing, packaging, and pricing device, the packaging section is disposed between the weighing section and the label printing and pasting section, so the distance between the weighing section and the label printing and pasting section becomes long. Therefore, after a series of tasks such as packaging the weighed product, printing and pasting the label after packaging, the processing speed is such that the next product is processed (in other words, one product is processed in one cycle). will drop significantly. Therefore, in this type of weighing, packaging, and pricing processing, one product is weighed, packaged, and priced in multiple cycles.

(Problems to be Solved by the Invention) In the conventional apparatus described above, the label printed and issued by the label printer does not contain the data of the product that has just been weighed, but the data of the product that has been weighed previously.

Therefore, even if a measurement error occurs during the weighing process or a packaging error occurs during the packaging process, the data for the incorrect product will also be sequentially stored in the storage unit of the label printer, and the incorrect stored data will remain unchanged. If a printed label is attached to a packaged product, or if a product is deleted midway through, the order of the data does not match the order of the sequentially sent products, and a label with other product data printed on the packaged product is attached. Causes problems.

Further, there are also problems in that data aggregation requires correction later.

Since it is very difficult to confirm the above-mentioned incorrect memory, it is necessary to correct the label again after pasting the label, which significantly reduces work efficiency.

The present invention has been made in view of the above-mentioned problems of the conventional technology, and its purpose is to detect abnormalities in the products in the weighing section and the label printing section. The purpose is to erase only the stored data of the product in which the abnormality has been detected from the storage section, and to prevent the label from being issued.

(Means for Solving the Problems) In order to achieve the above object, the method of the present invention includes a weighing process of weighing a product, a packaging process of automatically packaging the product after measurement is completed, and a label printer for storing required data of the product. a printing and pasting step in which the labels are sequentially printed on the labels and the labels are pasted on the packaged products that have been packaged; and a transport means that transports the products or packaged products between the weighing and packaging steps, and between the packaging and printing and pasting steps. In an apparatus in which products are transferred intermittently at predetermined intervals, a detection means for detecting an abnormal state of the product is provided between the weighing step and the printing and pasting step, and a detection signal from the detection means is used to send the product to the label printer. Delete the stored data of the corresponding product.

Abnormal conditions for the above product include: [] The weight of the product measured in the weighing section is not within the allowable range, and the weight is abnormal, such as being less than or more than that. [] The product is not properly packaged due to a malfunction in the packaging section. Cases such as when a product is left in the device or when a product on the transfer section is missing due to rejection of defective products or a malfunction in the packaging section. Use a container.

(Function) According to the above means, the product that is intermittently transferred at predetermined intervals from the weighing process to the printing and pasting process passes through the detection means provided between the processes, but if an abnormality occurs at any stage. When detected, the weighing data of the corresponding product for which the detection signal was output is erased from the storage section of the label printer, and no labels are printed or issued, and the data of normal products are printed and issued one after another.

(Embodiment) Hereinafter, embodiments of the present invention will be described based on the drawings. As shown in FIG. Packed product a′ after packaging is transferred to packaging department B.
It consists of a transfer section E that goes out from the
and E are constituted by belt conveyors, and the label printer C is installed on the transfer section E. Weighing unit A weighs product a placed on the weighing pan, 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 transferred onto the belt conveyor of the transfer section D, either manually or by a mechanical carrying means linked to the weighing operation, and sent to the packaging section B.

In the packaging section B, the product a is automatically wrapped in a packaging material such as a stretch film having extensibility, and the wrapped product a' is automatically carried onto the conveyor of the transfer section E. .

As shown in FIG. 2, the label printer C is composed of an input device 1, a control mechanism 2, a printing device 3, and a label pasting device 4.The input device 1 has various keys such as a numeric keypad and display fields, and the keys Through the operation, necessary data of the product, such as unit price, date of processing, barcode data, etc., are input into the control mechanism 2.

The input device 1 may have an array structure integrated with the label printer C or a structure installed near the weighing section A, but in the embodiment, a case where it is installed on the top surface of the packaging machine is illustrated.

The control mechanism 2 includes a storage section 5 that stores barcode code system and other data, a control section 6 that operates the printing device 3 and the labeling device 4 in a predetermined form according to input signals, an input device 1, and a weighing section. A
The system is comprised of an arithmetic processing section that receives input signals from the computer, processes the input signals, and calculates prices, etc.

The printing device 3 prints the data of the product a stored in the storage section 5 of the control mechanism 2 in a timely manner on the labels 8 which are pasted on a mount at regular intervals and transported intermittently according to a printing command.

The label pasting device 4 is located directly above the transfer section E, and attaches the label 8 printed by the printing device 3 and fed out to the bottom surface of the corresponding pack product.
It is applied by spraying when a' is transferred directly below the transfer section E.

The product a is sequentially weighed one by one in the weighing section A and sent to the packaging section B, and the product data is also sequentially sent to the control mechanism 2 of the label printer C and sequentially stored in the storage section 5. Patsuku products
storage section 5 according to the order in which a' is transferred on the transfer section E.
The label is outputted from the printer 3, printed on a label 8 by the printing device 3, and pasted onto the packaged product a' by the pasting device 4.

Therefore, what is the abnormal state of the above products a and a'? [I] Cases where the weight of product a measured in weighing section A is not within the permissible range, and is less than or above that, and the weight is abnormal.[] Packaging section B In the case that normal packaging is not performed due to a malfunction in the equipment, or products a and a' are stuck in the equipment, etc. [] Defective products are removed or the transfer part,
This refers to cases where products a and a' on D and E are missing on the way.

In the case of [] above, the control mechanism 2 detects the signal of the label printer C input from the weighing unit by detecting the weight and outputs the detection signal, []
In the case of , the abnormality is detected in the packaging section B and a detection signal is issued, and in the case of [], a detector etc. is installed on the transfer sections D and E to detect the missing product and a detection signal is issued. put out.

Alternatively, in any of the above abnormal conditions [ ] [ ] [ ], a detector is installed on the transfer section E immediately in front of the label printer C to detect the missing product a' at that position and output a detection signal.

The detection signal is sent to the storage section 5 of the control mechanism 2 of the label printer C, so that the stored data of the corresponding products a and a' are automatically erased.

It should be noted that the above-mentioned abnormal state and detection means are not limited thereto, and each part does not need to detect all the abnormal states.

In the label printer C, the printing device 3 and label pasting device 4 do not operate for the stored data erased by the means, so that labels are not issued.

It is also optional to erase the stored data and to activate alarm means such as a lamp or a buzzer based on the detection signal.

Now, referring to FIG. 3, an explanation will be given of a method of detecting an abnormality when the product detector 10 for detecting the presence or absence of the transferred product a' is installed on the transfer section E of the apparatus (FIG. 1).

FIG. 3A shows a synchronization signal of the device that is transmitted at regular intervals, which is synchronized with the transfer interval of product a.
2, 13, and 14, and product a
Let us take as an example a case where the product _A2 is carried onto the transfer section D in the state shown in FIG.

The registers 11, 12, 13, and 14 take in data for each synchronization signal regardless of whether or not a product is being weighed. That is, if the synchronization signal is received when no weighing is being performed or when the weight has not stabilized yet, zero data (hatched in the figure) is input into the register 11.

However, when the weight becomes stable after weighing and a synchronization signal is received, the measured value data a ₁ ′a ₂ ′, a ₃ ′, a ₄ ′, and a ₅ ′ are taken into the register 11. Therefore, if product a is delivered to transfer section D in the state shown in Fig. 3B, register 1
_{1 , 12, 13, and 14 are shifted} sequentially as shown _in FIG. Its presence or absence is detected by the detector 10 immediately before the detection.

The presence or absence of detection by the detector 10 is shown in FIG. Therefore, if product _A2 is missing on the way,
When the data a ₂ ′ comes to be called, the detector 10 detects an abnormal state in which there is no product a ₂ , and the detection signal P enters the control mechanism 2 and outputs the product a ₂ stored in the register 14 . The data a ₂ ' is erased, the printing device 3 does not operate, and label printing is prohibited.

(Effects of the Invention) As described above, in the weighing/packaging/pricing device, when an abnormal condition of the product between the weighing section and the label printing and pasting section is detected, the corresponding error condition is stored in the storage section of the label printer. Since the stored data corresponding to the product is erased, it is possible to prevent the issuance of wasteful labels that are printed with incorrectly stored information, eliminate mismatch between the product and the label, and prevent data aggregation errors.

Therefore, it is possible to provide a weighing, packaging, and pricing device that improves workability and has high accuracy.
