DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label attaching apparatus for automatically attaching a label to a product being conveyed.

[0002]

2. Description of the Related Art A label sticking apparatus for automatically sticking a price label to packed products (products stored in a tray and wrapped with a stretch film) such as fresh food such as meat and fish displayed in a supermarket or the like. Is commonly referred to as an "automatic pricing device". This automatic pricing apparatus attaches a label to a product moving on a conveyor, and there are affixing methods such as an air type by blowing air and a pressure contact type in which a label suction surface is pressed against the product. In these systems, for example, as shown in FIG. 16, the end of the product 7 being conveyed by the pasting conveyor 4 is detected by the product detection sensor S, and the product 7 is held by the label printing / pasting machine 2 from the detection time. The label sticking operation is performed after a lapse of a predetermined time (hereinafter, referred to as “sticking timing T”) obtained from a moving time for moving to the lower part of the label 8 or the like.

[0003] Recently, when displaying a packed product at a supermarket or the like, there has been a strong demand for a position where a label to be attached to the product is attached so as to give a good impression to customers as much as possible. For example, when displaying a product, make sure that the end of the label does not come off from the product at the corner off the center of the product so that the product can be sufficiently checked, and that the label is attached parallel to the product. Etc. are required. In order to respond to these requests, as shown in FIG.
It is necessary to improve the accuracy of the label 8 in the left-right direction and the up-down direction L3 of the label 8 with respect to.

Conventionally, the position L2 of the label attached to the product in the left-right direction has been adjusted by adjusting the above-described attachment timing T. On the other hand, the vertical distance L3 is
The position of the label printing / pasting machine 2 is automatically or manually moved in a direction perpendicular to the conveying direction of the pasting conveyor 4, or the product guide 9 is provided on the pasting conveyor 4 as shown in FIG. This is performed by positioning the product with respect to the label 8 held by the label 2.

[0005]

In this automatic pricing apparatus, a price label is automatically attached to a product while the product is being conveyed. It is used in combination with the device. For this reason, the transport speed of the pasting conveyor 4 can be changed so as to match the transport speed of the devices connected before and after. In addition, even when the automatic pricing device is used alone, the conveying speed of the attaching conveyor 4 is changed according to the size and properties of the product. For example, in the case of a product such as a lunch box or sashimi, the value of which decreases when its contents collapse, the transport speed cannot be increased. When the length of the label is long, it is necessary to reduce the transport speed in order to secure label printing by the label printing / pasting machine 2. As described above, there are many factors that determine the transport speed of the attaching conveyor 4 of the automatic pricing device at the work site. For this reason, the conventional automatic pricing apparatus is configured so that the attaching timing can be changed. Therefore, conventionally, it is necessary to adjust the sticking timing every time the conveying speed of the sticking conveyor 4 is changed, which is very troublesome. Also, if you forget to adjust the position, the label affixing position will vary and the product will not only look bad when displayed, but in extreme cases the end of the label will come off the end of the product and the label will stick out due to the back of the label. There is a risk of peeling.

More recently, when a plurality of automatic pricing devices are connected to a single management device (host computer) and data relating to work instructions are transmitted from the management device to the pricing device, centralized data management is performed. There is. in this case,
The above-mentioned sticking timing T is also transmitted from the management device to the automatic pricing device and is set, but in this case, the label attaching position varies if the transport speed of the attaching conveyor is not constant in each automatic pricing device. Would. That is,
In the conventional automatic pricing device, the application timing T must be readjusted every time the transport speed of the application conveyor changes, or the transport speed of the application conveyor of each automatic Since it is not constant, there is a problem that the position control of the label 8 in the left-right direction L2 is more difficult than the position control of the label 8 with respect to the product 7 in FIG.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a label sticking apparatus in which the label sticking position does not vary even when the conveying speed of the sticking conveyor is changed.

Next, the operation of the label sticking apparatus will be described with reference to the flowchart of FIG. In this device, the operator inputs the product number of the product to which the label is to be attached from the operation unit 15 of the console 1 so that the console 1
The following processing is started under the command of the CPU 11 in the above. It is assumed that the product file shown in FIG. 7 and the work instruction file shown in FIG. 8 have been read from the management device via the communication interface 16 in the RAM 13 of the console 1. Here, the product file is a file containing information necessary for printing on a label, and is a file containing data such as a product name and a price for each product number. In the present embodiment, the position L2 where the label is attached to the product is also stored in the product file. On the other hand, the work instruction file is a file in which data on the number of works, which is the number of products to be labeled for each product number, is stored. Please note that these product files,
The work instruction file may be a file that is requested from the management device and received and stored when the product number is input.

When the product number is input in this way, data necessary for printing, such as the product name and price of the product number, and the label attaching position L2 for the product are stored in the RAM.
13 and is displayed on the display unit 14. In addition, the work quantity corresponding to the product number is called from the work instruction file from the work instruction file, displayed on the display unit 14, and set in the work number register. Here, the sticking position L2 represents the distance from the end of the product 7 on the transport direction side to the label 8 when the reference is the front end as shown in FIG. 10A. On the other hand, FIG.
When the rear end is used as a reference as shown in FIG. 0 (b), the distance from the end of the product 7 opposite to the transport direction to the label 8 is represented. In the following description, the front end reference in FIG. 10A will be described as an example. By the way, the positioning of the label 8 in the vertical direction with respect to the product 7 shown in FIG. 17 is the same as the conventional method, and the description is omitted.

When the operation is started, first, a sticking timing T, which is a time from when a product is detected by the product detection sensor S to when the label is stuck, is calculated (step s1). The method of calculating the sticking timing T will be described in detail with reference to the flowchart of FIG. First, the conveying speed P of the goods by the attaching conveyor 4 is detected (step s11). This detection is performed based on the detection result by the tachometer K.
That is, since the transport speed is a function of the number of rotations of the drive motor M of the attaching conveyor 4, if the number of rotations is known, the transport speed P can be calculated. Therefore, the transport speed is obtained from the function given in advance and the rotational speed which is the detection result of the tachometer K.

Next, the sticking timing T is calculated (step s12). This calculation method is obtained by T = (L1 + L2) / P-T0 (1). In this equation (1), “L1” corresponds to FIG.
Is the distance from the detection position of the product by the product detection sensor S to the label 8 as shown in FIG.
It is assumed that it is stored in AM13. Also, "L2"
Is the sticking position called by inputting the product number, and "P" is the transport speed obtained in step s11. Also, "T
"0" is the operation time from when the sticking command is output from the console 1 to the label printing / sticking machine 2 until the label is actually stuck to the product, and is assumed to be stored in advance. Finally, the calculated sticking timing T is set in the sticking timing register TR. Thus, the calculation of the sticking timing T in step s1 is performed.

Next, it is determined whether or not a product has been detected based on the output of the product detection sensor S, and the process proceeds to the next step on condition that the determination result is "Yes" (step s2). When the result of the determination in step s2 becomes "Yes", the timer of the sticking timing T set in the sticking timing register TR is started. That is, the timer for the time T is started (step s3). Next, the label is printed and issued by the label printing / pasting machine (step s4). Printing is performed by the print head 22 under the control of the printing unit 31, and the printed label is peeled off from the backing paper by the dispenser 24 and issued. The issued label is held at a predetermined position of the label printing / pasting machine 2 with the label pasting side down using the negative pressure of the blower. Next, it is determined whether or not the counted time matches the sticking timing T stored in the sticking timing register TR, that is, whether or not the timer has timed out, and proceeds to the next step on condition of “Yes”,
In the case of "No", the time measurement is continued (step s5).

If the result of the determination in step s5 is "Yes"
Is attached under the condition (step s6). Attachment of this label is carried out by a command from the label attaching section 32.
By switching 3, the pressure by the blower is changed from negative pressure to positive pressure, and the printed label 8 is blown off the product 7. Finally, it is determined whether the processing for the number of works read from the work instruction file has been completed (step s7). If the result of the determination is "Yes", the process is terminated. If the result is "No", the process returns to step s2 to print and attach a label for the next product.

As described above, the sticking timing T measured in the processes of steps s3 and s5 is determined by the transport speed P in step s1.
Is calculated based on this. For this reason, even if the conveyance speed of the goods by the attachment conveyor 4 changes, the attachment timing T is automatically set without the need to manually adjust the attachment timing T. Further, since the sticking timing T is calculated according to the transport speed P, the sticking position L2 designated for each product can be accurately controlled.

(Second Embodiment) FIG. 11 is a diagram showing an electrical configuration of a label sticking apparatus according to another embodiment. In this figure, parts corresponding to the respective parts in FIG. 4 are denoted by the same reference numerals, and description thereof will be omitted. The difference between FIG. 11 and FIG. 4 is that the motor control circuit 44 shown in FIG. 5 is controlled by the PCU 11 in the console 1 instead of the tachometer interface 35 for taking in the signal from the tachometer K. is there. That is, in the present embodiment, instead of detecting the transport speed P of the product by the attaching conveyor 4, the sticking timing T is calculated from a preset transport speed P, and the motor control circuit 44 Thus, the rotational speed of the drive motor M is controlled.

In the following, a description will be given of how the operation of the present embodiment in the flowchart of FIG. 6 and the operation of the first embodiment are changed by such a change. Console 1
It is assumed that the product file shown in FIG. 12 is read in the RAM 13 in place of the product file shown in FIG. Here, the difference between the product file in FIG. 7 and the product file in FIG. 12 is that the transport speed P is further set for each product number in the product file in FIG. And
When the operator inputs the product number of the product to which the label is to be attached from the operation unit 15, the attachment position L2 and the transport speed P are called out together with the print data such as the product name. Then, the rotation speed of the drive motor M of the attaching conveyor 4 is determined based on the transport speed P, and the rotation of the drive motor M is driven by the instruction of the CPU 11 via the motor control circuit 44 so as to be the determined value. In the detection of the transport speed in step s11 in FIG. 9, the transport speed P called from the above-described product file is used, and the sticking timing T in step S1 is calculated. Since the transport speed P is thus detected based on the set value data, it is not necessary to provide a tachometer K for detecting the rotational speed of the drive motor M in order to detect the transport speed P.

(Third Embodiment) In the calculation of the sticking timing T at step s1 in FIG. 6, after the sticking command is output from the console 1 to the label printing / sticking machine 2 as shown in the equation (1), the sticking is actually performed. An operation time T0 until the label is attached to the product is required. In the above embodiment, the operation time T0 is stored in advance, but in the present embodiment, the operation time T0 is determined based on the label height H in FIG. 3 or the distance H 'between the label and the top surface of the product. The difference is that the calculation is performed.

First, a method of determining the operation time T0 using the label height H in FIG. 3 will be described. First, it is assumed that the operation time table shown in FIG. This operation time table is a table used for obtaining the operation time T0 based on the label height H. Before the calculation of the sticking timing T in step s12 in FIG. 9, the label height H is detected by the detecting means for detecting the label height H, that is, the detecting means for detecting the height of the label printing / pasting machine 2, The operation time T0 is calculated based on the operation time table and stored in the RAM 13 or a predetermined register. The operating time T0 is determined as H.ltoreq.H1.fwdarw.t1H1 <H.ltoreq.H2.fwdarw.t2H2 <H.ltoreq.H3.fwdarw.t3H3 <H.fwdarw.t4 from the table, where the obtained label height is "H". As described above, the operation time T0 is obtained from the label height H.

Incidentally, even if the label height H in FIG. 3 is the same, if the product height H0 is different, the distance H 'between the label and the product upper surface changes. Therefore, the above label height H
In the method of obtaining the operation time T0, an error occurs in the operation time T0 due to the difference in the product height H0, and as a result, the positional accuracy of the sticking position L2 decreases. Therefore, a method of determining the operation time T0 based on the distance H 'between the label and the upper surface of the product so that the label attaching position L2 to the product can be accurately controlled will be described below.

First, in the RAM 13 of the console 1, FIG.
It is assumed that a product table including data of the product height H0 is read for each product number as shown in FIG. Then, after input of the product number by the operator and FIG.
Prior to the calculation of the sticking timing T in step s12, the label height H is detected by the detecting means for detecting the label height H, and the product height H0 corresponding to the product number is read from the product table of FIG. . Then, the height H 'between the label and the upper surface of the product is obtained from H' = H-H0. An operation time table similar to the operation time table shown in FIG. 13 in which the operation time T0 with respect to the distance H 'between the label and the upper surface of the product is put in advance, and the operation time T0 is determined based on this table. Alternatively, it is stored in a predetermined register. The height H0 of the product may be detected by providing a height detection sensor in the transport path of the pasting conveyor 4.

By determining the operation time T0 based on the label height H or the distance H 'between the label and the upper surface of the product, the height of the label printing / applying machine 2 with respect to the conveying surface of the application conveyor 4 or the height of the product The change in H0 prevents the labeling position from varying.

In the first to third embodiments, as shown in FIGS. 7, 12, and 14, the sticking position L2 is the sticking position of the label indicated for each product number in the product file. Although it was obtained by L2, it is not limited to this. For example, the sticking position may be set from the operation unit 15 of the console 1 irrespective of the product number.

In the first to third embodiments, the method of attaching a label is performed by switching the negative pressure and the positive pressure of the blower in the label printing / applying machine 2 to perform the label attaching operation. , But is not limited to this. For example, a pressure bonding type for pressing the label suction surface against the product may be used. Further, in the above-described embodiment, the case of the upper surface (applied on the top) of the product is described.

The method of detecting the transport speed P in step s11 of FIG. 9 may be a method of detecting the transport speed of a product by further providing a transport speed detection sensor on the transport path of the attaching conveyor 4. For example, as shown in FIG. 15, detection sensors S1 and S2 for detecting a product position are provided, the distance between the two detection sensors S1 and S2 is L, and the time when the product 7 is detected by the detection sensor S1 is t1. The time at which the product 7 is detected by the detection sensor S2 is defined as t2, and the transport speed P may be calculated by P = L / (t2−t1). At this time, the detection sensor S2
May also be used as the product detection sensor S in FIG. That is, the detection of the transport speed P in step s11 may be performed by any method as long as the actual transport speed of the product can be known.

In the first to third embodiments, the sticking timing T is calculated in step s1 after inputting the product number as shown in FIG. 6, but the present invention is not limited to this. Absent. For example, the sticking timing T may be calculated when the transport speed P is changed, or may be calculated at regular intervals. Also, the sticking timing T may be calculated each time the label is stuck once.

In the first to third embodiments, the label is attached based on the front end shown in FIG.
The rear end reference shown in FIG. In this case, the label is applied after the application timing T elapses after the rear end of the product is detected by the product detection sensor S. The calculation of the sticking timing T is as follows: T = (L1′−L2) / P−T0 (2) Here, "L1 '" is the distance along the transport path from the commodity detection sensor S shown in FIG. 1 to the front of the label held by the label printing and pasting machine 2, and "L2" is the distance of the commodity 7 in FIG. The distance from the rear end to the label 8, "P" is the transport speed, and T0 is the operation time. However, in the case of the rear end reference,
It is necessary to lengthen the distance L1 'so that the sticking timing T in the equation (2) does not become negative.

Further, in the above-described embodiment, the description has been given by taking a fixed price as an example, but a weighed value for obtaining the price tag price from the product weight and the unit price may be used. Also, the case of a label with a price has been described as an example, but for example, a point-of-production information management system (POP)
The POP label used in n) may be used. Further, a label that is printed in advance may be used. Also, the products are not limited to packed products. Furthermore, to be able to change the label printing and pasting machine 2 to be used,
A configuration in which the label printing and pasting machine 2 is installed on a transport path of the pasting conveyor 4 using a moving table may be employed.
