Thus, the vertical width W and the height H of the product F are detected (measured). The detection data is transmitted from the packaging mechanism controller I to the weighing label printer controller G.

Step SP7: The CPU 36 as the tray type identifying means refers to the label sticking condition determination table (see FIG. 15) stored in the RAM 38, and refers to the width L and the length of the product F received from the packaging mechanism controller I. The type of tray is identified based on the detection data (type of tray) of the width W. Then, by the CPU 36 as the reading means, the tare weight (the weight other than the tray weight or the net weight of the product) and the labeling condition (labeling coordinates X0, Y0 and the labeling angle) are read from the RAM 38 based on the identified tray type. A) and are read and set.

Step SP8: The CPU 36 obtains the net weight NG (= G-FG) from the weight G of the product from the weighing section 40 and the tare weight FG set at step SP7, and the product stored in the RAM 38. File (Fig. 1
The price PR of the merchandise F is calculated from the unit price U and the net weight NG that are called from (see 4). For example, when the quoted price of the unit price U represents the value at 100 g, the price PR is
It is calculated as (NG × U) / 100.

Step SP9: In the packaging mechanism controller I,
The CPU 52 determines (generates) various data (packaging control data) for controlling the packaging operation from the horizontal width L, vertical width W, and height H of the product F (tray). The generation of this data is performed using a conversion table stored in advance in the RAM 55, but since it is not directly related to the essence of the present invention, its detailed description is omitted.

Step SP10: The mechanism drive unit 57 controls the packaging operation based on the data determined in step SP9, and the packaging machine A packages the product F. Step SP11: In the measurement label printer control unit G,
The CPU 36 controls the printing unit 42 to display the product F on the label.
The information (product information) about the product F such as the product name, weight, unit price, price, processing date, effective date, etc. is printed, and this label E is issued to the label issuing port 7.

Step SP12: The suction section drive section 43 (the drive mechanism C2) as the label sticking control section drives the label suction section C1 under the control of the CPU 36 to stick the label, as described in detail below. Based on the conditions, control is performed to attach the label E to a predetermined position of the product F in a predetermined direction.

The details of the processing in step SP12 will be described with reference to the flowchart shown in FIG. That is, the product name, price, unit price,
When data such as weight, effective date, and bar code is printed and the label E is issued to the label issuing port 7, the following processing is executed.

Step SP20: The label suction portion C1 located at the initial position (origin) is moved to the issuing port 7 and the label E is sucked onto the suction surface 8 (at this time, the adhesive surface of the label E is the lower side). Has become). Step SP21: From the label application condition called in step SP7, the label standby position (X,
Z) and the sticking timing time T are set.

Here, the label standby position (X, Z) is a standby position where the label suction unit C1 starts the operation of attaching the label to the product at a predetermined timing, and this X data is
As shown in FIG. 21, the horizontal distance from the initial position (origin) of the label suction portion C1 to the label standby position is shown. Z data is from the initial position (origin) to the label standby position as shown in FIG. Represents a vertical distance.

The X data is calculated by the following equation (1) from the distance relationship shown in FIG. X = XC-LR + X0 (1) However, XC ... Distance from the initial position (origin) of the label suction unit C1 to the center of the transport path (the center of the product when there is no displacement) (see FIG. 21) LR ... Length of the right half of the product detected by the length detection sensors 3a, 3a '(see FIG. 10) X0 ... Data obtained from the labeling condition (see FIG. 16)

The Z data is calculated by the following equation (2) from the distance relationship shown in FIG. Z = (Z0-Z2) -H (2) However, Z0 ... Vertical distance from the initial position (origin) of the label suction portion C1 to the transport surface (constant value: determined mechanically) Z2 ... Label Vertical distance (constant value) from the standby position (X, Z) to the label bonding position (upper surface of the product F) H ... Height of the product F detected by the sensor 3b

The Z2 data determines the position of the label E on the product F in the Y direction together with the later-described sticking timing time T so that the label adhesion position does not vary depending on the product height H. It is set to a constant value (so as to satisfy the label sticking condition Y0 shown in FIG. 16).

The sticking timing time T is a delay time from when the product F is detected by the sensor 44 (T = 0) to when the label suction portion C1 is started to descend from the standby position (X, Z). The label adhesion position in the Y-axis direction on F is determined. Therefore, when time T = 0, Y0
If the conveyance speed of the product F is D (mm) per second in the case of setting such that = 0, the sticking timing time T is
It is calculated by T = Y0 / D. However, Y0 is obtained from the label attachment condition (see FIG. 23).

Step SP22: The label sticking portion C1 is moved to the set label waiting position (X, Z). The movement to the label waiting position (X, Z) is determined by the number of steps of the motors M1 and M2. Step SP23: The motor M3 is driven to rotate the label sticking portion C1, and the orientation of the label E is determined based on the angle A of the label sticking condition called in step SP7.

Step SP24: Product detection sensor 44
By referring to FIG. 13, it is checked whether or not the product F is located at a predetermined position (labeling position) (step S).
P24: loop from NO to step SP24).

Step SP25: If the product F is located at a predetermined position (labeling position) (step SP2)
(4: YES), the sticking timing time T set in step 21 is set in a timer (not shown), and time counting is started. Step SP26: It is checked whether or not the timer has timed up (whether or not the pasting timing time T has passed) (step SP26: loop from NO to step SP26).

Step SP27: When the timer times out (step SP26: YES), the up-down motor M2 is driven to lower the suction portion C1. At this time, the product F is located below the suction portion C1, and the label E sucked by the suction portion C1 is brought into contact with the product F and attached.

Step SP28: Labeling sensor F
4 (51) (see FIG. 18), it is checked whether or not the suction portion C1 comes into contact with the product and the label is attached to the product F (step SP28: loop from NO to step SP28). Step SP29: When the label E is attached to the product (step SP28: YES), the label suction unit C1 is moved to the initial position (0, 0). As described above, the label sticking position and sticking direction set as the label sticking conditions are reflected, the label is stuck to the product F, and a series of label sticking operations are completed.

In the above-described embodiment, the X data of the standby position of the label sticking portion (suction portion) is expressed as X = XC-LR +
Then, the label is attached so that the distance X0 from the right end of the product F is constant, as shown in FIG.
Therefore, even if the placement position of the product F deviates to the left and right in the width direction and a deviation occurs between the center of the product F and the center of the transport conveyor, the label is calculated because the X data is calculated using the LR data. E can be stuck in place.

On the other hand, instead of the LR data, the product F
It is also possible to obtain the X data by using the lateral width L of the (tray) and the displacement amount δL of the placement. That is, as shown in FIG.
The center of the product F (tray) is the center of conveyance (predetermined reference position)
On the other hand, when it is deviated to the left by δL, the relational expression of L = LL + LR (3) δL = LR- (LL + LR) / 2 = (LR-LL) / 2 (4) holds, and this The following expression (5) is derived from the relational expression. LR = δL + L / 2 (5)

Therefore, the same result can be obtained by using "δL + L / 2" as the LR data in the equation (1) for calculating the X data, and the horizontal width L of the tray and the shift amount δL are used instead of the LR data. be able to. That is, the X data (label sticking position) can also be obtained by the following equation (6ï��) in which the shift amount δL is reflected. X = XC-LR + X0 = XC- (δL + L / 2) + X0 (6)

By the way, according to the above-described embodiment, the deviation amount δL is detected by the product width detection sensor 61 (see FIG. 13), and the product width detection sensor 61 detects the deviation amount δL. It also serves as a detection means. That is,
The lateral width L of the product F (tray) is simultaneously detected by a sensor that detects the deviation amount δL of the product.

Therefore, it seems that there is no difference between the equations (1) and (6), but according to the equation (6), the lateral width L of the product is the preset data for each product number. Can be used. Therefore, it is not always necessary to detect the lateral width L by the sensor, and it is also possible to detect the lateral width L by also using the width detection sensor equipped in the conventional packaging machine. Needless to say, it is also possible to detect the lateral width L of the product and the deviation amount δL by separate sensors.

In the above embodiment, the label sticking condition is set based on the size of the product F (tray), but in general, the label sticking position is set at the corner of the product in most cases. Therefore, when it is necessary to draw the customer's attention to a specific product, it is sufficient to attach a label at a position different from other positions. Therefore, when the label sticking condition corresponding to the tray containing the products is not set, the label sticking may be performed under the predetermined label sticking condition regardless of the size of the tray.

Further, the type of product (tray) for which the label sticking condition is set is stored, and based on the type,
It may be configured to determine whether the label is attached under the set label attachment condition or the label is attached under the predetermined label attachment condition regardless of the tray type.

Specifically, a special label sticking tray file (not shown) in which the type of product (tray) using the set label sticking condition (special label sticking condition) is defined is created in advance. Then, as shown in FIG. 25, the size of the product (tray) is identified (step SP3).
0), it is determined whether or not the special label attachment condition is used (step SP31).

When the special label attaching condition is used (step 31: YES), the label attaching condition is set based on the size of the product (tray). On the other hand, when the special labeling condition is not used (Step 3
1: NO), and a predetermined pasting condition set in advance is set.

Further, it is possible to select whether to attach the label under the stored label attaching condition or to attach the label under the predetermined label attaching condition regardless of the size of the product (tray). . Specifically, as shown in FIG. 26, the operator is in the normal mode in which the label sticking condition set in advance regardless of the size of the product (tray) is used, or the label according to the size of the product (tray). Set whether it is a special mode that uses pasting conditions.

Here, when the normal mode is set (step SP40: YES), preset label sticking conditions are set (step SP41). In contrast,
When the special mode is set (step SP40: N
O), label attachment conditions are set according to the size of the product (tray).

Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and the present invention includes a design change and the like within the scope not departing from the gist of the present invention. Be done. For example, although the sensor is used as the tray size detection method, the tray size may be detected by pattern recognition processing using an image processing technique.

The label attaching conditions can be modified in various ways. For example, the origin of the label sticking position (X0, Y0) may be another corner or center of the product and is not particularly limited. The sticking angle A is not limited to the illustrated one and can be set arbitrarily. Sticking position (X0, Y
Although 0) is aligned with the center position of the label sticking portion C1, it is not limited to this and may be the center position of the label, for example.

Further, the size of the product (tray) is detected and the label attaching condition is set, but not limited to the size, for example, a bar code may be detected as long as the type of the product can be identified. Any means may be used. Also, only the label adsorption part is supposed to move,
The entire label sticking device may be movable, and may have any structure as long as it can stick a label at a predetermined position on a product at a predetermined angle. Further, in the above-described embodiment, the weighing, packaging, and pricing machine is taken as an example, but the present invention is not limited to this, and is applied to other devices such as a packaging, weighing, pricing machine or weighing and pricing machine. It is also possible.
