Description

  The present invention relates to a weighing device and a package weighing system including the device.

There has been proposed a weighing value adding device that identifies a type of a product by reading a bar code attached to the product in advance (Patent Documents 1 and 2).
JP-A-6-198253 (summary) Reality 2-36631 (Fig. 1)

  By the way, in Europe, for example, a whole chicken and other contents are packed into a packaging material by a vacuum pack, and then weighing is performed. However, such a vacuum-packed product cannot read the barcode because of the wrinkles on the packaging material.

  Here, the quality of the product is differentiated from the consumer by using packaging materials having different colors and designs according to the quality of the whole chicken. Therefore, one packaging machine that wraps the same type of quality whole chicken is made to correspond to one unit with weighing value set to a unit price corresponding to the quality, and a label printed with a barcode or the like after packaging It is possible to issue and paste However, since the production capacity of the packaging machine is extremely lower than that of the weighing device, the production capacity cannot be improved.

  On the other hand, it is also conceivable to connect a plurality of packaging machines to a single weighing device. However, since a plurality of types of packaged products flow at random, it is difficult to sort the types of products.

  Therefore, a main object of the present invention is to provide a weighing value adding device capable of discriminating the type of product and automatically issuing a label corresponding to the type. Another object of the present invention is to provide a packaging weighing value adding system capable of weighing a plurality of packaging machines with a single weighing value attaching device.

  In order to achieve the above object, the weighing device according to the present invention measures the weight of a product while transporting a packaged product packaged by one type of packaging material among a plurality of types of packaging materials. By specifying the type of the packaging material based on the detected value from the conveyor, the detection means for detecting the packaging material in the packaging state in order to identify the packaging material in a state in which the product is packaged, A specifying means for specifying the type of product packaged in the packaging material, a product information storage unit for storing at least a unit price per unit weight of each product for each type of the product, and the specified product are read. Price calculating means for obtaining the price of the product based on the unit price and the measured weight, label issuing means for printing the price on a label and issuing the label, and attaching the label on which the price is printed to the product Labeling And a means.

  According to the present invention, since the type of product can be classified according to the type of packaging material, a label can be automatically issued, and the label can be attached to the product. Can be placed. Therefore, by using this apparatus, when a plurality of types of products are randomly transported from a plurality of packaging machines, labels suitable for the products can be issued and affixed.

In the present invention, the packaging material has a unique color and pattern for each packaging material, the detection means detects a color distribution determined by the color and the pattern, and the specifying means is based on the color distribution. It is preferable to specify the type of packaging material.
According to this aspect, the product can be sorted even if the shape of the packaged product is indefinite or the size is not fixed.
Note that “color distribution” refers to the area, length, ratio, etc., of each color detected by the detecting means.

  In the present invention, the detection means includes a light receiving element that receives light reflected from a spot on the surface of the packaging material being transported, and whether or not the spot has a preset color based on the light received by the light receiving element. Color determining means for determining whether or not the identifying means stores a detection storage unit for storing the number of detected spots for each color determined by the color determining means for a plurality of spots for one packaging material; A threshold storage unit that stores a threshold for the number of spots set for each material and for each color, a detection spot number that is stored in the detection storage unit, and a spot number that is stored in the threshold storage unit for each color It is preferable that a comparison means for specifying the type of packaging material is provided.

According to this aspect, since detection and classification can be performed using a so-called color sensor, software for specifying a packaging material is significantly simplified compared to using a CCD or the like.
Further, when the number of types of packaging materials is about several, for example, unlike a CCD, detection can be performed with a small number of spots of about several to several tens, so that the processing capability is remarkably improved.

In the present invention, the packaging material has predetermined first and second regions in the flow direction, and the specifying unit does not adopt information on the number of detected spots from the second region, and from the first region, It is preferable to specify the packaging material by using the information on the number of detected spots.
According to this aspect, even when it is difficult to discriminate the entire packaging material, the packaging material can be sorted based on information from local or partial areas.

In the present invention, in the product information storage unit, different unit prices are set and stored for each weight range for products packaged by the same packaging material, and the type of the packaging material specified by the specifying unit and the measurement It is preferable that the unit price of the product is read from the product information storage unit based on the weight measured by the conveyor and the price of the product is calculated.
According to this aspect, even when the unit price varies depending on the weight range, the price can be calculated.

On the other hand, the packaging weighing value addition system of the present invention is arranged upstream of the weighing value adding device, and each of the plurality of packaging machines for packaging contents using a predetermined packaging material, and the plurality of packaging machines A packaging weighing value system including a transport line for transporting in a state in which different products packaged together are mixed, and in a state in which packaged products having different types of packaging materials are mixed, Goods are introduced into the weighing device from the transport line.
According to this system, it is possible to assign a weighing value to a plurality of packaging machines with one weighing value device, and the number of weighing value devices can be reduced.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
Product M:
First, as an example of a product to which a packaging measurement value is attached by the present system, a whole chicken packaged by a vacuum pack is described.

Whole chickens have different unit prices per unit weight depending on the type of production area, etc., and as shown in FIG. 1 (a) and FIGS. 2 (a) and (b), packaging materials (for example, packaging) according to the type Bag) is packaged (for example, a packaging pack) by Mw. The packaging material Mw has a unique color and pattern for each packaging material Mw.
Note that “halftone dots” and “hatching” attached to the packaging material Mw indicate colored colors, and the same “halftone dots” means the same color.

  On the other hand, even for the same kind of chicken, the unit price per unit weight differs because the taste and texture differ depending on the size. Therefore, the unit price per unit weight is different even for the same kind of chicken packaged by the packaging material Mw having the same pattern Mc shown in FIGS.

System configuration:
Next, a system for attaching the package weighing value of the above-described product M will be described.
As shown in FIG. 3, the present system includes a plurality of packaging machines 1, a conveyor 2 (conveying line) 2 that conveys the product M packaged by the packaging machine 1, and weighing and values for the product M. And a weighing value attaching device 3 for performing the attaching.

  A plurality of packaging machines 1 are provided for each type of chicken. An operator selects chickens and feeds them into the packaging machine 1 corresponding to the type. The packaging machine 1 wraps chicken using a previously set type of packaging material Mw. By such sorting and packaging, a product M packaged with a packaging material having a pattern according to the type of chicken is produced.

  The products M packaged by the packaging machine 1 are respectively sent onto the transport conveyor 2 and transported to the weighing value adding device 3 by the transport conveyor 2. The transport conveyor 2 performs transport in a state where different products M packed by the plurality of packaging machines 1 are mixed. Therefore, the weighted apparatus 3 is introduced in a state where mixed products M having different types of packaging materials Mw are mixed.

  The weighing value attaching device 3 detects the type of the product M supplied by the transport conveyor 2 and measures the product M, and a label on which the product name, price, etc. according to the product M are printed is displayed. After affixing to, the product M is sent downstream.

Weighing device 3
Next, the measurement value attaching device 3 will be described.
Configuration of the weighing value adding device 3;
As shown in FIGS. 4A and 4B, the weighing value addition device 3 includes an introduction conveyor 11, a weighing conveyor 12, and a sticking conveyor 13 in order from the upstream along the conveyance direction X.
A centering device 11 a that moves the product M to the center in the width direction W substantially orthogonal to the conveyance direction X of the product M is provided on the introduction conveyor 11. The product M is centered by the centering device 11a and then conveyed to the weighing conveyor 12.

In the weighing conveyor 12, the type of the product M is specified by the color sensor 4 according to the color of the packaging material Mw and the pattern Mc. On the other hand, the product M is weighed by the weighing means 6 provided on the weighing conveyor 12.

Color sensor 4;
The color sensor 4 detects the color distribution determined by the color and pattern of the packaging material printed on the packaging material Mw of the packaged product M. As shown in FIG. It is provided above. As shown in FIG. 4A, the color sensor 4 is installed approximately at the center in the width direction W of the weighing conveyor 12.

Configuration of the color sensor 4;
As shown in FIG. 6A, the color sensor 4 includes a sensor controller 40, an amplifier 41, a light receiving element 42, and a light projecting element 43.
As shown in FIG. 4B, the light projecting element 43 projects visible light toward the product M being conveyed. The light from the light projecting element 43 shown in FIG. 6A is projected so as to be focused on a spot S (FIGS. 1 and 2) having a diameter of about 5 mm to 10 mm, for example.
The light receiving element 42 receives the light reflected from the spot S on the surface of the packaging material Mw of the product M. The light receiving element 42 converts the received light amount into a light receiving signal composed of an electrical signal for each of the three primary colors of light, and sends it to the sensor controller 40 via the amplifier 41.

The sensor controller 40 performs color discrimination based on the light reception signal, and includes a color discrimination unit 40a, a color setting unit 40b, and a color condition storage unit 40c.
As shown in FIG. 4B, the color condition storage unit 40c stores, for each color number, a threshold value for each of the three primary colors of light corresponding to the color printed on the packaging material Mw, such as “紺” or “orange”. Are stored in association with each other. The association between the color number and the threshold value is performed by the color setting unit 40b.

As shown in FIGS. 1 and 2, when a product is conveyed on the weighing conveyor 12 at a constant speed, a sensor is detected from the light receiving element 42 in FIG. A light reception signal is sent to the controller 40. The color discriminating means 40a discriminates the color No. for each spot based on the stored contents of the color condition storage unit 40c. The color sensor 4 transmits a signal of the determined color No. to the control unit 30 in FIG. Therefore, color No. signals corresponding to a plurality of spots S are sequentially transmitted to the control unit 30 for the packaging material Mw of one commodity M.
As the color sensor 4, for example, a color sensor such as CZH35S manufactured by OMRON Corporation (registered trademark) can be employed.

Product detector 5;
The product detector 5 shown in FIG. 5A includes, for example, an optical sensor, and is provided at both ends in the width direction W of the weighing conveyor 12 shown in FIG. The commodity detector 5 is provided on the upstream side of the weighing conveyor 12. The control unit 30 in FIG. 5A detects the product M based on the detection signal from the product detector 5.
As the commodity detector 5, for example, an article detector described in Japanese Patent Laid-Open No. 6-198253 can be employed.

Weighing means 6;
The weighing means 6 includes weight detection means such as a load cell, for example, and transmits a weight signal of the product M on the weighing conveyor 12 (FIG. 4B) to the control unit 30. The control unit 30 calculates the weight of the product M based on the weight signal.

Label applicator 7;
As shown in FIG. 4B, the label sticking device 7 is provided above the sticking conveyor 13 and performs label printing and sticking of the label on the product M.
As shown in FIG. 5A, the label sticking device 7 includes a label issuing means 71 for printing a label and a label sticking means 72 for sticking the issued label to the product M.

Control unit 30;
The control unit 30 includes a CPU 31 and a memory 32.
The CPU 31 has functions of a comparison unit 31a and a price calculation unit 31b.
The memory 32 is provided with a detection storage unit 32a, a product information storage unit 32b, and a threshold storage unit 32c.

  Based on the color No. signal from the color sensor 4, the color discrimination means 40a discriminates a plurality of spots S (FIGS. 1 and 2) for one packaging material Mw in the detection storage unit 32a. The number of detected spots for each color number is accumulated and stored.

As shown in FIG. 5B, in the product information storage unit 32b, the product number, packaging material number, product name, weight range, unit price per unit weight, and the like are stored in advance in association with each type of product M. ing.
As described above, even for the same type of product M, the product M having a different unit price depending on its weight stores a unit price that is different for each weight range with respect to the same packaging material number. ing.

  As shown in FIG. 5 (c), the threshold value storage unit 32c stores the packaging material number and the threshold value consisting of the range of the number of spots for each color in association with each other for each type of packaging material. .

  The comparison means 31a compares the number of detected spots stored in the detection storage unit 32a with the range of the number of spots stored in the threshold storage unit 32c for each color, and specifies the packaging material number. .

Means for identifying the packaging material;
Here, as shown in FIGS. 1 (a) and 2 (a), since the color and the pattern are different for each type of the packaging material Mw, the number of detection spots for each color constituting the pattern is different. Therefore, the comparison unit 31a in FIG. 5A reads the number of detection spots for each color from the detection storage unit 32a, and for each color, the detection spot number is stored in the range of the number of spots stored in the threshold storage unit 32c. By comparison, a matching packaging material number can be searched and specified.
Therefore, the CPU 31 having the function of the comparison unit 31a constitutes a specifying unit that specifies the type of packaging material based on the number of detected spots for each color distribution.

  Based on the packaging material No. and the weight calculated based on the weight signal from the weighing means 6, the price calculating unit 31b obtains the packaging material No. from the product information storage unit 32b and within the weight range. The unit price of the matching product is read out, and the price of the product M is calculated by multiplying the unit price by the weight.

The CPU 31 creates print contents based on the price, the product name and unit price of the product M, and transmits the print contents to the label sticking device 7.
The label sticking device 7 causes the label issuing means 71 to issue a label based on the printed content, and causes the label sticking means 72 to stick the label to the packaging material Mw of the product M at a predetermined timing.

  The CPU 31 specifies the packaging material registration mode in which the number of spots of each color and the packaging material No. are associated with each other for the packaging material Mw and stores the settings in the threshold value storage unit 32c, the packaging material, and calculates the price from the weight of the product. And a mode with a measurement value for issuing and sticking a label.

Operation of the device;
Next, the operation of this apparatus will be described.
First, the color sensor 4 is caused to read a specific part of the product without transporting the product M, and the colors constituting the pattern of each packaging material Mw in the color condition storage unit 40c (FIG. 6B) of the color sensor 4 Register the settings for No.

Packaging registration mode;
Next, registration is performed for setting the number of spots of the color that constitutes the pattern of the product to which the measurement value is attached with this apparatus.
When the operator performs a predetermined operation on the weighing value addition apparatus 3 and specifies a packaging material number to be stored in the threshold value storage unit 32c in FIG. 5, the packaging material registration mode starts.

  When the product M is conveyed on the introduction conveyor 11 of FIG. 4, the product M is centered toward the center of the introduction conveyor 11 in the width direction W by the centering device 11 a. When the product M is transferred from the introduction conveyor 11 to the weighing conveyor 12, the product detector 5 detects the tip of the product M.

  Based on the detection signal, color discrimination by the color sensor 4 is started, color discrimination for each spot S in FIG. 1 is performed, and a color No. signal from the color sensor 4 is sequentially transmitted to the control unit in FIG. 30. The control unit 30 adds up the number of signals of the same color color No. for each color and stores them in the detection storage unit 32a. The integration of the color numbers for each color is performed until the product detector 5 finishes detecting the rear end of the product M, that is, for one product M.

  The CPU 31 determines the range of the number of spots of each color corresponding to the designated packaging material No. by repeating the detection and integration of the color Nos. As shown in c), the threshold value is stored in the threshold value storage unit 32c.

  In addition, as shown in FIGS. 1 (a) and 1 (b), the registration of the packaging material No. is made to detect a large number of products M of the same packaging material and different sizes, and the range of the number of spots is determined. decide. Thereby, it becomes possible to discriminate | determine the goods M from which size differs by the same kind of packaging material.

Weighing value mode;
After registering the packaging material, the operator performs a predetermined operation on the weighing value addition device 3 to set the CPU 31 to the weighing value addition mode, and then starts the packaging weighing value addition system. As described above, at the time of operation of the present system, the packaged products M having different types of packaging materials are mixed and introduced from the conveyor 2 in FIG.

  When the product M shown in FIG. 4A is conveyed on the introduction conveyor 11, the product M is centered toward the center in the width direction W of the introduction conveyor 11 by the centering device 11 a. When the product M is transferred from the introduction conveyor 11 to the weighing conveyor 12, the product detector 5 detects the tip of the product M.

  Based on the detection signal, color discrimination by the color sensor 4 is started, color discrimination for each spot S in FIG. 1 is performed, and a color No. signal from the color sensor 4 is sequentially sent to the control unit 30. Sent. The transmission of the color No. is continued until the merchandise detector 5 no longer detects the merchandise M. As a result, the detection storage unit 32a in FIG. The number of detected spots is stored.

Next, the comparison means 31a compares the number of detected spots stored in the detection storage unit 32a with the range of the number of spots stored in the threshold value storage unit 32c for each color to identify the packaging material number. . On the other hand, the CPU 31 calculates the weight of the product M based on the weight signal from the weighing means 6.
Thereafter, the price calculation means 31b reads the unit price of the product that is the packaging material No. and matches the weight range from the product information storage unit 32b based on the packaging material No. and the weight, and the unit price Is multiplied by the weight to calculate the price of the product M.

  The CPU 31 creates print contents based on the price, the product name and unit price of the product M, and transmits the print contents to the label sticking device 7. Based on the printed content, the label sticking device 7 causes the label issuing means 71 to issue a label, and then causes the label sticking means 72 to stick the label to the product M on the sticking conveyor 13. . After the label is attached, the product M is transported downstream, and operations such as boxing are performed.

As described above, the weighing value adding device 3 can identify the type of the product M by classifying the type of the packaging material based on the color No. signal from the color sensor 4. Even for the same type of product M, the type of the product M having a different unit price per unit weight can be specified by calculating the weight based on the weight signal from the weighing means 6.
Therefore, in this system, by using the weighing value addition device 3, it is possible to attach a measurement value to the plurality of packaging machines 1 with one weighing value addition device 3.

Packaging with the same number of spots:
By the way, as shown in FIGS. 2A and 2B, there is a packaging material having a pattern in which the number of spots coincides even with different types of packaging materials Mw.
Further, in the case of “wrapping material No. 04” and “wrapping material No. 05” shown in FIG. 7A, when the number of detected spots is, for example, orange 3, white 5, yellow 2, both packaging materials Since it is within the range of the number of spots of Mw, the packaging material Mw cannot be determined.

  In such a case, as shown in FIGS. 8A and 8B, stickers Ms of different colors are attached to the packaging material Mw of the product M. The number of detection spots varies depending on the sticking of the seals Ms having different colors, and the packaging material can be identified.

  As shown in FIG. 2, some packaging materials have a mark Md called a domino mark for identifying the type of the product M visually recognized by an operator, and are printed on the packaging material Mw. The seal Ms may be attached to the domino mark.

First and second regions A1, A2:
By the way, as shown in FIGS. 1A and 1B, when the variation in the size of the product M is large, the variation in the number of spots for each color stored in the threshold value storage unit 32c increases, and the number of detected spots. Applies to a plurality of types of products, making it difficult to determine the type of product M.

  Here, as shown in FIGS. 9 (a) and 9 (b), after inserting the contents such as chicken into the bag-shaped packaging material Mw, the product M extends the packaging material Mw to release the air inside. The upper part of the packaging material Mw is crimped and sealed while sucking. In the manufacture of the product M, the contents are inserted while pulling the upper part of the bag-shaped packaging material Mw, and therefore, as shown in FIGS. The portion near the upper portion Ma of the packaging material Mw is stretched more greatly.

Therefore, the number of detected spots is divided into a first area (predetermined area near the bottom Mb) A1 in the transport direction X and a second area A2 (other areas) behind. Depending on the product, the information on the number of detected spots from the second region A2 that is greatly expanded is not adopted, and only the information on the number of detected spots from the first region A1 having a small degree of expansion is used, and the packaging material Mw is used. It may be specified.
As described above, by adopting information on the number of spots of only the local or partial area A1 of the packaging material, it is possible to determine the type of the product even when it is difficult to determine the entire packaging material.

  As a method of dividing the first area A1 and the second area A2, only information from the first one of the detected spots to a predetermined number may be adopted. In other words, information about only the number of detection spots obtained for the part corresponding to the region to be detected is employed.

If the number of colors detected by the color sensor 4 is large, two or more color sensors 4 may be provided as shown in FIG.
Further, as a detection means, a CCD camera may be used instead of the color sensor.

Label inspection device:
Here, conventionally, in a label inspection apparatus that captures a label with a camera and inspects the quality of the label by image processing, the timing of capturing an image with the camera is a “position detection sensor” that inspects the position of the inspection object. It was either installed separately and determined based on the output signal, or manually by pressing the “image capture” button. In this case, it is costly to install a position detection sensor separately, and it is troublesome to manually press the “image capture” button.

  Therefore, instead of shooting only when the inspection object comes under the camera, the camera always shoots and monitors whether the inspection object comes under the camera with a high-speed detection method. When it is determined, a structure that performs detailed inspection of the label (which takes time) is adopted.

To determine whether there is an inspection object under the camera, the brightness of “any point in the photographed image” is acquired, and it is determined whether there is an inspection object by the following method.
1. If the brightness falls below the threshold during standby (lighting OFF), it is determined that the inspection object has come under the camera. (If the object to be inspected comes under the camera, external light is blocked by the object to be inspected, so the brightness decreases.) → Turn on the light if it is determined that the object to be inspected has come under the camera.
2. If the lightness value falls below the threshold value during inspection (during illumination ON), it is determined that the inspection object has been removed from the camera (out of frame). (If the inspection object comes off, the light will not be reflected by the inspection object, and the reflected light will not reach the camera, so the brightness will decrease.) → If it is determined that the inspection object comes off the camera Turn on the lights.

  Since the inspection object is detected based on the magnitude relationship between the brightness value (at an arbitrary point) and the threshold value, the presence or absence of the inspection object can be determined at high speed. As a result, automatic inspection can be started without reducing the inspection timing and inspection speed of detailed information.

  The inspection apparatus that has been provided with a position detection sensor for the inspection object until now does not require a position detection sensor and can reduce costs. Further, in the inspection apparatus that has manually pressed the “image capture” button until now, the troublesomeness of pressing the button is eliminated.

Inspection method for printed labels:
By the way, there is a label inspection apparatus that takes an image of a label with a camera and inspects the printed content of the label printed by image processing. In such an inspection apparatus, when the label printing process is divided into two or more stages and the contents printed at each stage are related, the individual printed contents are inspected. No sex test was performed.
For example, as shown in FIG. 11B, when printing item names such as expiry date, processing date, price, content, and the contents corresponding to the item names, first, FIG. ), The item names are printed in advance, and then the contents corresponding to the item names are thermally printed. After the thermal printing, the printed content of the label is inspected based on the printed content of the label imaged by the camera.

However, in the conventional inspection method, as shown in FIG. 11C, when the contents corresponding to the item names are shifted downward and thermally printed, the inspection of only the printed contents results in a pass determination.
In particular, as shown in FIG. 11C, when the thermal printing is shifted, the expiry date becomes blank and the processing date is printed as “05.10.07” of the print content corresponding to the expiry date. Therefore, it should be judged as rejected.

Therefore, the relevance between the item name that is the print content of the first stage and the content that is the print content of the second stage is registered in advance, and the relevance is inspected at the time of inspection.
That is, as shown in FIG. 11D, for example, an allowable range indicated by a halftone dot is registered in advance on the right side of the “expiration date” character that is the print content in the first stage, and the content print area at the time of inspection. Whether date data corresponding to the expiration date is printed is determined. If the content printing area is not printed, the content is rejected.
Similarly, an allowable range indicated by a broken line is registered for the processing date, price, and content, and it may be determined whether or not the print content corresponding to the item name is printed in the allowable range at the time of inspection. Good.

  As described above, whether or not the print content corresponding to the item is printed within the allowable range corresponding to the pre-printed item, that is, the “function to inspect the relationship with other printed matter” is provided. Thus, it is possible to determine whether the inspection target is really good or bad, and to increase the added value of the inspection apparatus.

Individual identification number inspection method:
Conventionally, the individual identification number of livestock, which is required to be printed by law, has been printed by the following method.
First, when the bulk meat that has arrived is cut, a succession label printed with an individual identification number (barcode) is issued and pasted.
Next, at the time of pricing work, the bar code (individual identification number) of the inherited label is read with a labeler, and a label on which the individual identification number is printed is attached to each product.
However, in this conventional method, since the printing of the individual identification number is completely operated offline, it is impossible for the label inspection apparatus to receive the correct individual identification number from the host, and the machine (label inspection apparatus) The individual identification number cannot be inspected.
For this reason, there is a possibility that a product without an individual identification number printed or a product with a label with an incorrect individual identification number attached may be shipped, resulting in serious damages such as penalties or loss of trust.

Therefore, the above-mentioned problems are solved by using an identification number inspection described below and a system for keeping the inspection history.
In the case of a line-type label inspection device (hereinafter referred to as “line-type label inspection device”) that is installed in a product production line and inspects the label of the product being conveyed on the conveyor
1. In conjunction with a labeler or a host computer installed at the front of the line type label inspection apparatus, the presence / absence of printing of the individual identification number and the individual identification data are acquired by communication and inspected.
2. In conjunction with a labeler or higher-level host computer installed in the previous stage of the line type label inspection device, only the individual identification number printing presence / absence information is acquired through communication, and the individual identification number printing presence / absence (C / D if necessary) ) Inspection.
3. Whether the individual identification number is printed or not based on the individual identification number printing information registered in the label inspection device, not linked to the labeler or host computer installed at the front of the line type label inspection device. C / D).

In the case of a label inspection apparatus (hereinafter, referred to as “sampling type label inspection apparatus”) that inspects one of the produced products.
4). In conjunction with the host computer, it acquires information on whether or not the individual identification number is printed by communication, or acquires information on whether or not the individual identification number printed in the label inspection apparatus is printed. When inspecting a product that requires printing of a fixed identification number, an instruction to scan the inherited label attached to a box (container) that carries the product is displayed on the screen of the label inspection device. When the operator scans the inherited label, the individual identification number data is acquired and the individual identification number of the product is inspected.

As the history inspected in 1 to 4 above, whether or not the individual identification number of the label is printed, the individual identification number data printed on the label, whether or not the individual identification number is printed, and the setting value of the individual identification number data (correct data) ) In the history.
In this way, by performing the inspection of the individual identification number, it is possible to eliminate inspection mistakes caused by human inspections and improve the quality of shipped products.

A low-cost method of providing a vibration sensor:
By the way, it is common for a scale to smooth out vibration due to disturbance by a digital filter or the like and extract weight data (DC component).
In the past, filtering has often been used in such a way that if it does not fit within a certain touch range, it is often judged that it is unstable and measurement is impossible. There is no function to constantly monitor
This is a problem that can be solved by arranging an acceleration sensor or the like in the body, but costs increase because parts such as a sensor, a harness to the sensor, a bracket, and an I / O are required.
For this reason, aircraft equipped with sensors (safety circuits in scales) have not been widely available.
However, in actual sites, there are various types of vibrations such as temporary vibrations caused by the movement of the transport vehicle, cases where workers are inadvertently touching the weighing machine, and items are poorly connected and are being vibrated. Sudden vibration may occur.
These cannot be determined by the current system, and may be treated as unstable measurement or mismeasured.

The G sensor is mounted on the board mounted on the peel-off device.
At this time, the mounting pattern is designed so that the G sensor is arranged in the vicinity of the mounting screw on the substrate.
The substrate is mounted on the chassis. At this time, a metal component having a high vibration transfer function is used as a coupling member that couples the substrate and the chassis.
When excessive vibration is detected by the sensor, a lock mechanism (such as an electromagnetic lock) that locks the free end is provided to protect the load cell.
If excessive vibration is detected by the sensor, there is a possibility that the inspection cannot be performed correctly. Therefore, the operation is forcibly stopped and the upstream device is also stopped.

By mounting the vibration sensor in the vicinity of the mounting screw on the substrate, the sensor can detect external vibration with high sensitivity.
Since it is directly mounted on the scale substrate, the cost is greatly reduced as compared with the case where only the G sensor is arranged independently.
When this sensor catches vibrations transmitted from the frame to the electrical chassis, it can be determined whether or not the weighing machine can be used in the correct environment, and a more accurate inspection can be performed.
When a large external impact is applied, the cell's forced protection mechanism works to prevent cell failure (the same role as the hard disk protection function).
When a large impact is detected from the outside or the floor, the line is urgently stopped to ensure a reliable inspection ("safe lock function").

Sorting apples:
By the way, in the conventional sorting of apples, etc., when the farmer sorts the house, except for the equipment that processes at high speed in the fruit selection field, the appearance is visually checked, the rank size is weight sorted by a scale, etc. Often an incoming sensor is used. For this reason, each is divided as a work process and requires a lot of labor.

  Therefore, a load cell is incorporated into a commercially available honey sensor, the rank selection function and the rank selection function of the honey sensor are combined, and the operator is notified by voice, lamp, etc. just by placing the apple on the measurement part of the honey sensor.

  Although the appearance is visually determined by the operator, the weight rank and the honey degree rank can be measured in one step, and the labor is halved. In addition, it is easy to select by notifying at the same time by voice and lamp.

Agricultural product selection:
Conventionally, in the sorting of agricultural products, in the case of a type that is not measured by a weight sensor (the shape is captured by a camera), the class sorting accuracy is poor. When several items with poor sorting accuracy are cut out, the yield often becomes extremely poor or minus weighing occurs.

Therefore, for example, if L (4 pieces), M (5 pieces), and S (6 pieces) are set to 150 g, the weight in L is further divided into 4 equal parts, M for 5 equal parts, and S for 6 equal parts. Sort out.
Each one is discharged simultaneously at the end of the discharge lane aligned one by one.
When an empty lane is generated due to a variation in the number of lanes, there is also a function of selecting a lane closest to the remaining lanes and an empty lane (necessary lane).

  Therefore, the problems of the prior art are improved, and the combination weighing machine in the next process is unnecessary, so that the capital investment can be suppressed and labor saving can be realized.

As described above, the preferred embodiments have been described with reference to the drawings. However, those skilled in the art will readily understand various changes and modifications within the obvious scope by looking at the present specification.
For example, as shown in FIG. 3, in the above-described system with packaging weight values, two devices with weight values 3 are provided, but one device may be provided, or three or more devices may be provided.
Moreover, what is necessary is just two or more packaging machines.
Further, two or more label sticking devices including a label issuing means and a label sticking means may be provided for one weighing conveyor, or a label may be stuck on the bottom of a product.
Accordingly, such changes and modifications are to be construed as within the scope of the invention as defined by the claims.
