DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label attaching method and an apparatus therefor, and more particularly, to attaching a security label for preventing theft, and in particular, attaching a security label together with a normal price label to a packed product in a supermarket or the like. And a device for implementing the method.

[0002]

2. Description of the Related Art Conventionally, a system has been adopted in which a security label is affixed to a product to prevent theft, and a bell or the like is sounded when a product is taken out of a store without settlement. I have. recently,
Even in packed products such as supermarkets, security labels are applied to expensive products and the like in order to prevent theft. In this case, it is suggested that a security label be attached below the price label in order not to impair the appearance of the product and to prevent the customer from knowing the attachment of the security label. Practical.

[0003] As a method of attaching a security label to the lower side of a price label, a label attaching device for a security label and a label attaching device for a price label are arranged along a product transport path, and the security label is attached first. A general method is to attach the product to a product and then attach a price label so as to cover the security label. However, the above-mentioned attaching method requires two label attaching devices,
There is a problem that the product conveyance path for label attachment becomes long and the device becomes large. Further, if the label sticking position control is not accurate, the security label will protrude from the lower side of the price label, and the appearance of the product will not only deteriorate, but also the sticking of the security label will be known.

[0004] Therefore, a security label smaller than the price label is pasted on the glued surface on the back side of the price label in advance, and then the price label with the security label attached is pressed against the product, whereby the price label and the security label are put on the product. Has been developed (US Pat. No. 5,897,741). However, in the above-mentioned conventional method and apparatus, the security label issuing device is arranged above the price label issuing device, the price label is issued and held so that the pasting surface thereof is on the upper side, and the price label is pasted. This is a configuration in which a security label is issued and dropped on the surface from above, and the security label is attached to the glued surface of the price label. When sticking a price label on the upper surface of a product, it is necessary to rotate the label by 180 degrees, which complicates the label sticking mechanism. Since the security label issuing device is arranged above the price label issuing device, the entire device becomes high and it becomes difficult to perform label setting and print head maintenance work. Since the security label is dropped from above and is attached to the glued surface of the price label, the attached state and the attached position of the security label are not stable. Since the next price label cannot be issued until after the security label is attached, the processing capacity is reduced.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, has solved the above-mentioned problems, simplified the label attaching operation, stabilized the attaching state and attaching position of the security label, and applied the label attaching. It is an object of the present invention to provide a label attaching method and an apparatus capable of improving the processing capacity of the apparatus and avoiding an increase in the size of the apparatus, making the apparatus compact and facilitating maintenance work.

[0006]

According to the label attaching method of the present invention, a price label of a product is issued, a security label is issued at a place different from the price label, and the price label is suction-held and held. The security label is adhered to the back side of the price label by pressing the glued surface of the labeled label against the top surface of the security label, and the price label and the security label are attached to the product by pressing the price label against the product. (Claim 1). Further, the label sticking apparatus of the present invention is provided with a price label issuing unit for performing the method, a security label issuing unit, a label holding unit, and a label sticking mechanism (claim 3).

According to this label sticking apparatus, as shown in FIG. 13, a price label La issued by a price label issuing unit is provided.
Is held by the label holding unit 51 (FIGS. 13A and 13B), and the price is obtained by pressing the glued surface of the back of the label La against the upper surface of the security label Lb issued by the security label issuing unit. The security label Lb is sucked and held on the back surface of the label La (FIG. 2B).
(C)). Then, by actuating the label holding unit 51 with the label sticking mechanism, the price label La is pressed against the product G, thereby sticking both labels La and Lb to the product (FIGS. (C) and (d)). The label attaching method is performed.

In order to minimize and simplify the label transfer operation of the label holding unit, the labels issued by both label issuing units are preferably transferred to the label holding unit at the same position. There is provided moving means for shifting the security label La issued by the unit to immediately below the price label suction-held by the label holding unit (claim 4). As a specific configuration of the arrangement of the label issuing section and the label sticking mechanism, a price label issuing section and a security label issuing section are arranged side by side on one side of the product transport path along the transport direction, and both label issuing sections are provided. The label receiving surface of the price label issuing unit is formed as a label receiving unit, and the label receiving surface of the security label issuing unit is configured to be movable to the transferring unit (claim 5). That is, both label issuing units are arranged using the side space of the product transport path, the label receiving surface of the price label issuing unit is used as a label transfer unit, and the label holding unit always holds the price label. Make the retention of the selection optional.
Further, the label attaching mechanism reciprocates the label holding unit between the label transfer unit and the label attaching position on the product transport path and enables the label holding unit to move in the vertical direction, and moves the suction unit of the label holding unit in a horizontal plane. It is configured to be rotatable (same item). The reciprocating movement of the label holding unit is a label carrying (conveying) operation, the vertical movement is a label receiving and attaching operation, and the rotating operation in the horizontal plane is a price label issuing attitude (orientation) and an attaching attitude. Is different, the operation is to turn the label to the sticking position.

The security label Lb is attached and held on the back surface of the price label La, but the security label Lb must not protrude from the back surface of the price label La, and should preferably fit in the center of the back surface of the price label La. It is. To that end, the security label issuing unit:
The dispenser is made to slightly protrude above the label receiving surface and the label receiving surface is formed so as to be inclined so as to rise toward the product transport path side. The position close to the top is defined as the lower limit of the lowering operation. As a result, the security label fits in the label receiving surface (dispenser tip position) separated from the issuing reference edge (dispenser tip position) in the label advancing direction when the label receiving surface is a price label, that is, fits within the back surface of the price label. Issued to the location. Further, the label holding unit stops when the label holding unit descends slightly above the dispenser, thereby preventing the label holding unit from colliding with the dispenser and giving an impact to the dispenser. For this reason, the end of the security label on the dispenser side is not completely adhered to the glue surface of the price label, but after that, the label holding unit is moved in the direction of the product transport path and the label is attached. When the price label is affixed to the product, there is no hindrance to the movement to the position, and the entire surface is affixed to the back surface of the price label.

Although the price label is attached to all products, there is a case where it is not necessary to attach a security label to products. Therefore, it is determined whether or not the product is a product to which a security label is attached. If the product is a product to which a security label is attached, the security label is attached to the product together with the price label as described above (claims). 2) In the case of a product to which a security label is not attached, only a price label is attached to the product without issuing a security label, or even when issued, without passing the security label to a label holding unit (claims 7 and 8). ).
The determination as to whether or not to apply the security label is automatically made based on data or the like stored in advance for each product (Claim 9). (Claim 10).

Then, the label holding unit 51 is raised and returned to the reference position (origin) (see FIGS. 12, 13 (b) and 13 (c)). At this time, the suction unit 53 of the label holding unit 51 stops at a position slightly higher than the case where the price label La is suctioned in order to avoid collision with the dispenser 36 (see FIG. 12).

(Step 5) The label holding section 51 holding the price label La (when the judgment in step 2 is "NO")
Alternatively, the label holding unit 51 holding the price label La and the security label Lb (the determination in step 2 is “YES”)
Is moved to the label pasting position above the carry-out section 16 and stands by. The label affixing position is determined based on the detection result of the product width detection sensor 21 described above. When it is necessary to change the direction of the label, the suction unit 53 may be moved 90 degrees, 180 degrees,
The direction of the label is changed by rotating by 70 degrees (the data of the label sticking direction is set in advance in the product file for each product). Then, the product detection sensor
When it is detected by 107 that the packaged product G has reached the predetermined position on the unloading section 16, the label holding section 51 is lowered to move the price label La or the price label La and the security label to the predetermined position on the upper surface of the product G. The label Lb is pressed and attached (see FIGS. 8 and 13D). The details of the structure of the drive mechanism 60 for moving the label holding portion 51 and the position control at the time of attaching the label are described in Japanese Patent Application Laid-Open No. Hei 9-77034 filed by the present applicant.

The present invention is not limited to the above embodiment, and the following configuration should be noted.
The stretch wrapping machine A to which the label sticking device B of the present invention is assembled is a device for performing weighing, packaging, and valuation work. Is also good.

In the above-mentioned label sticking apparatus, the first issuing unit
Although the case where 30a is composed of one price label issuing unit has been described, two price label issuing units may be selectively operated to issue a predetermined price label. Further, the mode has been described in which the security label Lb is attached when the second issuing unit 30b issues the security label Lb, in other words, only when the security label Lb is attached, the security label is issued each time. Since Lb is the same, the second issuing unit 30b may issue a security label in advance and issue the next security label every time the security label is attached. The security label Lb can be used irrespective of the type as long as it can be attached to the glued surface of the price label and can be attached to a product.

Further, the label issuing unit 30 has the first issuing unit 30a and the second issuing unit 30b arranged side by side along the product carrying direction of the packaging unit 3 in the direction perpendicular to the product carrying direction. , More specifically, may be arranged above the discharge conveyor 17 along the discharge direction. In addition, the label issuing unit 30 is of a movable type so that one of the first issuing units 30a and 30b can be selectively positioned at the label transfer unit. The label holding unit 51 is connected to the first issuing unit 30a and the second
It may be moved between the issuing units 30b.

The label sticking mechanism 50 is not limited to the driving mechanism 60 including the first driving mechanism 61 to the third driving mechanism 63. For example, when the label issuing unit 30 is of a stationary type, in addition to the reciprocating movement (X movement), the vertical movement (Z movement) and the rotating operation (R movement) by the driving mechanism 60, the first issuing unit 30a and the second 2 movement (Y movement) between the two issuing units 30b is required. Alternatively, the first issuing unit 30
If the attitude of the price label La issued by a and the affixing attitude to the product match, it is not necessary to perform the rotation operation (R movement).

According to the first and third aspects of the present invention, a price label and a security label are issued at different places, but the price label is pressed onto the upper surface of the security label and the label is attached. The stuck state and the stuck position of the security label are stable, and the security label can be stuck to the product with the price label covered. Then, since the labels are pressed against the product and attached, there is no need to make the label attaching mechanism perform an operation of rotating the label by 180 degrees, and the label attaching operation can be simplified and a simple attaching mechanism can be adopted. In addition, the height of the security label issuing device can be reduced as compared with the case where the security label issuing device is arranged above the price label issuing device, so that the device can be prevented from being enlarged and the label setting and print head can be set. Maintenance work becomes easy.
Furthermore, since the issued price label is first suctioned and held, after holding the label, the next price label can be issued and put on standby before the security label is stuck, and the label can be stuck accordingly. Ability is improved.

According to claims 4 and 5, a conventional twin labeler type label sticking apparatus is disclosed.
This can be easily implemented by using the sticking mechanism adopted in Japanese Patent Application Laid-Open Publication No. HEI 10-222 (1995). According to claim 6, without giving an impact to the peeling member of the security label,
A security label can be affixed to the center of the price label's glued surface.

According to the second, seventh and eighth aspects, it is possible to select only products that need to be attached with a security label to prevent theft, so that the desired effect can be achieved while sparing the use of expensive security labels. can get. According to the ninth aspect, the determination as to whether or not to issue a security label is automatically performed based on the preset data and the like, so that it is possible to selectively secure only necessary products without burdening the operator. Labels can be applied.
According to the tenth aspect, since the number of issued security labels is stored, inventory management and remaining amount management are possible and can be used as basic data when measuring the effect of attaching a security label. .
