2. Description of the Related Art Food products and the like in a supermarket are displayed on a tray together with a film on which the product is wrapped with a film and a label on which the product name or the like is printed is affixed to the film. In order to automatically apply a label to such a product, a label applying device is used. Further, there is also used a weighing device that weighs the product, prints a price corresponding to the net weight of the product on a label, and affixes the product to the label. Is obtained by subtracting the tare weight (tray weight or (tray weight) + (film weight)) from the weighed value (see, for example, Japanese Patent Publication No. 3-48451). Here, conventionally, a tray to be used is determined for each type of product, and therefore, a label attaching position and a tare weight are determined for each product.

(Input operation means) 11, a label printer 12, a controller 14 with weighing and packaging values (control means), and the like are connected. The microcomputer 3 includes a CPU 4 and a memory 5. The CPU 4 includes an image processing unit 40, a dimension correcting unit 41, and a tray specifying unit 42. On the other hand, the memory 5 includes a product information storage unit 50 and a tray information storage unit 51.

No. of product call No. In correspondence with the product, one or more tray Nos. To be used besides the product name and unit price for each product. Is stored. The information of the product name and the unit price is used as label print information.

On the other hand, the tray information storage unit 51 shown in FIG. 6B stores, for each tray type (for each tray number),
A tray size consisting of a tray width (long side dimension) W and a depth (rectangular side dimension) D, a tray weight Wt for taring, and a film N determined by the tray depth dimension
o. The processing contents of the product, such as (film width) and film length (cut length) (packing conditions) determined by the width of the tray, label sticking position and sticking position (label sticking conditions) determined by the tray size, are stored. ing. In addition, the film weight Wf may be stored for each tray type (for each tray No.) in order to weigh the product after wrapping the product with the film together with the tray. The product information storage unit 50 and the tray information storage unit 5
The information of No. 1 is input from the touch screen 10 and the stroke key unit 11 in FIG.

The image processing means 40 shown in FIG. 4 detects the position of the apparent planar edge of the tray T from the luminance information input from the CCD camera 2 by the method described below. From the position of the edge, the apparent size of the tray T is calculated. The first image storage unit 52 of the memory 5 previously stores an image of the weighing conveyor 100 in a state where the tray T is not placed thereon, while the second image storage unit 53 stores the image of FIG. An image in a state where the tray T is placed is stored. The image processing unit 40 in FIG. 4 obtains the position of the edge Te on the tray T from the change in the brightness of the first and second image storage units 52 and 53.

On the other hand, the first and second reference lines C1 and C2 are arranged vertically and horizontally in the image pickup area A of the CCD camera 2 shown in FIG.
Are set, and the reference lines C1 and C2 and the imaging area A
The intersection O _N the end of, based on the distance between the intersection P _N of the two reference lines C1, C2 and edge Te, the tray T
Is calculated. For example, the apparent width Wa of the tray T is calculated by the following equation (1). Wa = W ₀ − (W ₁ + W ₂ ) (1)

Next, a method for obtaining the actual size of the tray T from the apparent size of the tray T will be described. As shown in FIG. 5B, when an image of a tray having a height H is taken and the planar dimension W of the tray T is measured, an apparent dimension Wa is a measured value. Here, the planar dimension W and the apparent dimension Wa of the actual tray T are expressed by the following equation (2). Wa: W = Ha: (Ha-H) (2) where Ha-H is the distance (height) from the imaging device to the edge Te of the tray Ha: the distance (height) from the imaging device to the transport surface 105 From the above equation (2), the actual dimension W of the tray T is expressed by the following equation (3). W = Wa · (Ha−H) / Ha (3) Therefore, by knowing the distance (Ha−H) from the imaging device to the edge Te of the tray, it is possible to know the actual dimensions of the tray.

The dimension correcting means 41 shown in FIG. 4 calculates the apparent dimension (width) Wa of the tray T shown in FIG. 5B by the height (Ha-H) to the tray in accordance with the equation (3). After correction, tray sizes W and D are obtained.

The tray specifying means 42 shown in FIG. 4 calculates the size (measured value) of the tray T obtained by the detection and calculation.
W and D are compared with the registered setting values of the tray stored in FIG. 6B. (Tray type) is specified. First, the tray specifying unit 42 sets the product call No. input from the stroke key unit 11. Tray No. corresponding to And each tray N read out
o. For each tray width W and depth D, the measured value and the set registration value are compared, and the absolute value ΔW of the difference for the width W and the absolute value ΔD of the difference for the depth D are determined. Subsequently, the tray specifying means 42 sets the tray having the smallest sum of the absolute values ΔW + ΔD as a candidate to be specified.

Next, the tray specifying means 42 determines whether or not the absolute values ΔW and ΔD are both within a predetermined measurement error range (threshold) ΔA. If the tray No. is within the tray No. Judge that it is. On the other hand, if one or both of the absolute values ΔW and ΔD are larger than the predetermined measurement error range ΔA, the tray specifying means 42
o. Is specified, the same operation as described above is performed for all types of trays, and the tray No. is selected from all the types of trays. To identify. In addition, tray No. is selected from all trays. If you cannot specify the tray, do not specify the tray.

The CPU 4 (reading means)
o. Is specified from the tray information storage unit 51 in FIG. The processing contents of the product are read out, and the processing conditions are output to the controller 14 with the weighing and packaging value. The CPU 4 executes the specified tray No. Is subtracted from the measured value to calculate the net weight Wc of the product M. For example, the specified tray No. , The tray weight Wt is read out, and the net weight Wc is obtained by subtracting the tray weight Wt from the weighed value. If the product is weighed after the entire tray is wrapped with film, the tray N
o. The film weight Wf is set and registered in advance for each
The specified tray No. , The tray weight Wt and the film weight Wf are read out, and the tare weight Wv (Wt
+ Wf) is subtracted from the measured value to determine the net weight Wc.
The CPU 4 causes the label printer 12 to print information on the net weight Wc calculated in this manner. In addition, the controller 14 with the weighing / packaging value specifies the specified tray No. Film No. And the product M is packaged based on the film length. The label sticking machine 13 sticks a label according to the output sticking position and sticking posture. Note that C in FIG.
PU4 is the tray No. If is not specified, the processing content of the product is calculated according to a predetermined arithmetic expression, and the processing content is output to the controller 14 with the weighing and packaging value. For example, the microcomputer 3 determines the tray weight Wt from the detected tray width W, depth D and height H according to the following equation (4). If the tray and the product are weighed after being wrapped with film, the film weight is calculated. Wf is obtained by the following equation (5), and the net weight Wc is obtained by subtracting the tray weight Wt or the tray weight Wt and the film weight Wf from the weight including the tare. Wt = Ct · {W · D + 2H · (W + D)} (4) where Ct: weight of tray per unit area Wf = Cf · {2 · (W + H) + L} (5) , Cf: film weight per unit length L: film overlap length

Next, the operation of the above configuration will be described. First, a registration mode is set in advance, and a product call N
o. , Product name, unit price and tray No. Etc.
Settings are registered from the touch screen 10 and the stroke key unit 11 for each product. Each tray No. The tray depth, width, tray weight Wt, film No. , Film length, sticking position and sticking posture, etc.
Register settings from. As the tray weight Wt, a value measured by placing an empty tray T on the weighing conveyor 100 can be registered.

On the other hand, when packaging a product, the packaging mode is set first. Next, the operator calls the number of the product to be packed. Is input, and the tray T on which the product M is placed is placed on the weighing conveyor 100, the weighing means 106 converts the output from the weight detector 101 into a weight, and
Output to When the weight signal is stabilized (the weight detector 101 is stabilized), the microcomputer 3 captures the luminance information from the CCD camera 2 and the height information from the ultrasonic distance meter 1.

Thereafter, the CPU 4 detects the edge Te of the tray based on the above-described method, obtains the apparent size of the tray from the edge Te, corrects the apparent size with height information, and obtains the width of the tray. Find W and depth D,
Identify the tray. The microcomputer 3 uses the specified tray N
o. Is subtracted from the weighed value including the tare, and the net weight is obtained.
0 and output to the label printer 12. Also, CPU
No. 4 is the specified tray No. Packaging conditions (film N
o. , Film length) from the tray information storage unit 51, and outputs the packaging condition (film No., film length) to the controller 14 with weighing and packaging value. Weighing and packaging controller 14
Controls the operation of the packaging machine on the basis of the packaging conditions (film No., film length) to package the product M. Further, the CPU 4 executes the specified tray No. Is read from the tray information storage unit 51, and the label pasting condition (pasting position, pasting posture) is output to the controller 14 with weighing and packaging value. The label printer 12 prints the net weight and the product name on the label and issues the label. The issued label is attached to the stretch-wrapped product together with the tray T according to the label attaching condition read from the tray information storage unit 51.

As described above, according to the present apparatus, the type of the tray is specified by comparing the detected size information of the tray with the registered size information, and the label attaching condition of the specified type of tray is stored in the tray information storage unit 51. , And control of label application to the product based on the read label application condition. Therefore, even when a plurality of types of trays are used for one product, the tray No. Can be automatically set without inputting a password. Therefore, weighing
The workability with the price is improved. Further, the label attaching position and the label attaching position can be arbitrarily changed for each type of tray. Further, according to the present apparatus, the packaging conditions of the specified type of tray are read from the tray information storage unit 51, and the operation of the packaging machine is controlled based on the read packaging conditions.
Even when a plurality of types of trays are used for one product, the tray No. , The packaging conditions can be set automatically. Therefore, the workability of packaging is improved. Furthermore, according to the present apparatus, the tray weight Wt is determined based on the specified tray type to determine the net weight. Therefore, even when a plurality of types of trays are used for one product,
Tray No. Without having to enter the
This net weight can be printed. Therefore, the workability of weighing and pricing is improved. In addition, there is no risk of forgetting to subtract (tare) the tare weight Wv. In addition, setting of each of these conditions is automatically performed by specifying the type of tray, so that weighing, packaging,
The overall workability with the price is greatly improved. Further, by also using the means for detecting the size of the tray, it is possible to suppress an increase in cost.

Incidentally, even if the tray is not specified or the tray cannot be specified, it is not possible to obtain the tray weight Wt from the above-mentioned formula (4), that is, from the size of the tray and the weight per unit area. it can. However, in this case, it is inevitable that an error occurs in the tray weight Wt. On the other hand, by specifying the type of tray as in the present embodiment, the accurate tray weight Wt weighed in advance by the weighing conveyor 100 can be known. Therefore,
An accurate net weight Wc is obtained.

By the way, the tray to be used is determined to some extent in advance depending on the type of the product (product name or the like). Here, in the above-described embodiment, first, the product call No. The tray is specified by selecting a tray from the types of trays corresponding to. Therefore, the product call No. Since the candidates for the tray specified by the above are narrowed down in advance, the specification of the tray is accurate and quick. As a result, an accurate net weight Wc can be obtained quickly.

By the way, the product information storage unit 5 shown in FIG.
If the dimensions of the trays registered for each of the products 0 are similar to each other, there is a possibility that the identification of the tray may be erroneous. Therefore, the same product call No. May be registered on condition that they have a dimensional difference equal to or greater than a predetermined value. For example, at least one of the tray width W and depth D is the same product call No. Only when there is a dimensional difference greater than or equal to a predetermined value with respect to the width W and the depth D of the other tray registered in the corresponding product call No. May be stored (registered) in the product information storage unit 50.

By the way, for products such as "eel kabayaki" and "sashimi", auxiliary materials such as "sag sauce", "wasabi" and "soy sauce" are stored in a tray together with the products, and weighed and valued. May be performed. In this case, it is necessary to subtract the weight of the secondary material in addition to the tare. On the other hand, the amount of the secondary material is, for example, 30 g in the case of one "eel",
In the case of two "eels", the weight varies according to the quantity of the product, such as 60 g. On the other hand, the type of tray also changes according to the amount of goods. Therefore, as shown in FIG. 7A, the tray No. is stored in the product information storage unit 50 in advance. The weight of the auxiliary material may be stored together with the weight, and the weight of the tray and the auxiliary material may be subtracted from the measured value to determine the net weight.

In the above embodiment, stretch wrapping is performed after weighing. However, as shown in FIG. 8A, weighing may be performed after stretch wrapping. For example, FIG.
As shown in (b), in a packaging weighing and pricing apparatus in which a carry-in conveyor 110 is provided upstream of the weighing conveyor 100 and a label pasting machine 13 is provided on a conveyor 120 downstream of the weighing conveyor 100, the packaging is carried out on the carry-in conveyor 110. Put the finished product. In the weighing and packaging apparatus, the tare weight Wv
It is necessary to obtain the net weight Wc by subtracting the film weight Wf from the measured value in addition to the tray weight Wt. In such a case, the weight of the film is determined to some extent by the size of the tray, that is, the type of the tray. Therefore, as shown in FIG. 7B, the tray information storage unit 51 stores the film weight Wf in addition to the tray weight Wt in the tray No. After the microcomputer 3 specifies the tray, the tray weight Wt and the film weight Wf are subtracted from the weighed value including the tare to obtain a net weight Wc, and a label printed with the net weight Wc is obtained. It sticks by the label sticking machine 13 of FIG.8 (b). In addition, when it is necessary to subtract the film weight Wf, the tray cannot be specified.
Alternatively, when the tray is not specified, the microcomputer 3 obtains the tray weight Wt and the film weight Wf according to the above-described equations (4) and (5).

The present invention is applicable not only to the weighing / packaging and valuation apparatus but also to a label pasting apparatus, a wrapping / applying apparatus, and a weighing apparatus (see JP-A-6-92338). it can.

In the above embodiment, the ultrasonic distance meter 1
And the dimensions of the tray were detected using the CCD camera 2
In the present invention, the mechanism for detecting the size of the tray is not limited. For example, when a carry-in conveyor is provided upstream of the weighing conveyor 100 shown in FIG. 1 (see Japanese Patent Application Laid-Open No. 7-257524), a large number of reflection-type photoelectric detectors 300 are provided as shown in FIG. The width W of the tray T is calculated from the number of the detectors 300 on which the reflected light is incident while moving on the carry-in conveyor, while the transmission-type photoelectric detectors 301 and 30 are calculated.
2, the depth D of the tray T may be calculated from the time during which the light is shielded and the transport speed while the tray T moves on the carry-in conveyor 100. When a centering device for centering the tray is provided, or when a pusher for pushing the tray from behind is provided, the dimensions of the tray may be detected from the stroke of the centering device or the pusher. Also, the height of the tray may be detected by arranging a large number of photoelectric detectors vertically.
Further, without directly detecting the actual dimensions of the width W and the depth D, the apparent planar dimensions and the area (information on the dimensions) of the tray captured by the piezoelectric sensor or the CCD camera are registered. Alternatively, the tray to be used may be specified by comparing with the above, and the pre-registered tare weight may be read from the specified tray.

When calculating the film weight Wf,
The film weight Wf may be corrected in consideration of the arrangement height of the products.
