Description

[Detailed description of the invention] The present invention relates to a label mounting method and a label mounting device.

To attach a heat-shrinkable synthetic resin film (hereinafter referred to as "heat-shrinkable film") in a tube shape around a container such as a bottle or can, first fold the heat-shrinkable film over itself and glue both edges together. A tube larger than the diameter of the container is formed, cut to the required length, fitted onto the container, and then heat-shrinked using hot air or the like. However, when heat-shrinking the tube fitted into the container, the tube is placed in a predetermined position (
For example, it is difficult to hold the bottle stably at the tip of the bottle mouth, around the body of the bottle), and it may be installed out of place, or it may cause unsightly wrinkles or twists on the lape. It is not uncommon for the finish to show scratches.

The present invention has been made in order to solve the above problem, and involves continuously feeding a long film coated with an adhesive at key points, cutting it into a required length, and cutting the film into a predetermined length for a container. By wrapping the label around the area and attaching it to the container surface with adhesive, the label will not be misaligned, wrinkled, or twisted.
To provide a label mounting method that allows a desired appearance and mounting ability to be obtained.

The label attachment method of the present invention involves continuously feeding a long film coated with adhesive in strips in the width direction of the film at required intervals, and dividing each adhesive layer into two. The film is cut and cut out as unit films, and
It is characterized in that the cut unit label is affixed to the outer surface of the container using an adhesive on both edges thereof.

The present invention also provides a feedrow μ for feeding a long film coated with an adhesive in strips in the width direction of the film at required intervals, and a long film for carrying out the above tube device method. A film suction drum that suction-holds the front end portion of the film, a cutter that cuts the film into unit labels so as to bisect the adhesive layer of the film suction-held on the suction drum, and a cutter located near the film suction drum. To provide a tube mounting device having a container rotating table for rotating a container around its axis, and a container transfer line connected to the container rotating table.

To explain the present invention with reference to the drawings, in FIG.
(5) is a feeder roll, (6) is a film suction drum that suctions and holds the leading end of a long film, and (8) is a container rotating table. (0 is an adhesive layer applied to one side of the film (G) in a band shape in the width direction of the film at a required interval.The adhesive layer (0 is an adhesive layer applied to a rotating drum in the film feeding line) The adhesive layer (C
) is approximately equal to the tube circumference of the unit label wound around ) of the container.

The suction drum (6) has a built-in vacuum suction mechanism (not shown) and has a vacuum suction port or slit (6.1) that opens on the drum surface. The leading end of the film that has reached the suction drum (6) is held between the circumferential surface of the suction drum (6) and the suppression row /l/ (7) that comes into contact with it, and is also exposed to the vacuum of the suction drum (6). It is held on the surface of the suction drum by suction force.

Furthermore, as shown in FIG. 5, the suction drum (6) is provided with a cutter OQ for cutting the film (G) inside thereof. The cutter QO is installed so that its cutting edge is oriented substantially perpendicularly to the surface of the drum, and a slit is provided in the drum surface for the cutting edge to protrude. The cutter QO is driven by a drive mechanism (not shown) so that its cutting edge protrudes outside the drum surface by a length corresponding to the thickness of the film to cut the film, and then retreats into the drum after cutting the film. It has become. Note that the number of cutters 01 is not limited to one, and a necessary number of cutters 01 may be arranged radially such that their cutting edges are substantially perpendicular to the drum surface, and cut the film in the same manner as described above.

The container rotation table (8) is connected to a rotational drive mechanism and a horizontal movement mechanism (not shown), rotates the placed container Q3) four times around its axis, and rotates the container CB) so that the side surface of the container CB) is a film with an adsorption drum surface. Repeat the operation of (g) approaching the adhesive layer (0) until it touches the adhesive layer (0) and then returning to the original position. The container may be fixed on the rotating table using a presser shaft (9) that hangs down from the mouth of the container coaxially with the rotating shaft (8, 1).

The container rotating table (8) has a container feed line (11/1).
A container transfer line consisting of a container feed line (11.2) and a container feed line (11.2) is connected, and the container is transferred to the feed line (11.1).
The container is placed on the turntable (8), a predetermined label is attached to the container, and then the container is placed on the delivery line (11) from the turntable (8).
・2) K is transferred and sent to the next process.

In the above device, the long film (to) is the original roll/I
It is unwound from /(1), passed through a guide row /l/ (2), a rotating drum (3), and then fed into an adsorption drum (6). The operation of cutting out the unit label from the film on the suction drum (6) and attaching it to the container will be explained with reference to FIGS.
11.1) onto the turntable (8) (Fig. 2),
Next, the rotary table and the suction drum (6) are brought close to each other, and the side surface of the container (B1) is moved to the container-facing point CP) on the circumferential surface of the suction drum.
(Figure 3). Next, the adsorption drum (6) and container (B1
) is rotated in the opposite direction of 1C at the same circumferential speed as shown by the arrow, the υ film (G) is transferred from the suction drum (6) to the container (Bl), and wound onto the surface of the container (B1) ( Figure 4). The film (G) wound around the container (B1) goes around the surface of the container, and the next adhesive layer (C2) on the film (G) is polymerized and pasted on the leading edge of the film. Once the adsorption drum (6) and the container turntable (8) have been attached, the rotation of the adsorption drum (6) and the container rotating table (8) is temporarily stopped, and the cutter 01 inside the adsorption drum (6) is pushed out from the drum surface to remove the overlapped adhesive layer (C2).
Cut the film (G) into two halves (Figure 5)
. The film wound up on the container surface is separated from the film (T) on the suction drum (6) as a unit rappel ρ. Next, the rotating table (8) is moved back to return the container (B1) to the container transfer line αυ (C (Fig. 6)), and the container (B1) is transferred from the rotating table (8) to the feeding line (11, 2). , send the next container (B2) onto the turntable (8) (7th
figure). Thereafter, the above operation is repeated for each container.

The suction effect of the suction drum (6) on the film (G) can be applied to the area in which the film comes into contact (the area from the film clamping point by the suppression row 1v (7) to the container facing point ψ). It is preferable to control the operation and stop of the vacuum suction in synchronization with the rotation of the drum so that the vacuum suction force is applied only to the circumferential surface of the drum and the vacuum suction is stopped on the circumferential surface other than that area. This also facilitates the transfer of the film (g) from the adsorption drum (6) to the container (13) at the point facing the container.

Instead of vacuum suction, other methods such as electrostatic attraction may be used to attract the film (g) to the circumferential surface of the attraction drum (6). In this case, if the electrostatic adsorption force and the adhesion force of the adhesive layer (C) to the container are balanced, the transfer of the film from the adsorption drum (6) to the container (I3) and
There is no problem in winding up the container.

The film (G) is wound up from the suction tram (6) to the container (6) as shown in Figure 8.
6) It is also possible to roll the drum a predetermined distance around the drum while in contact with the drum.

In addition, the cutter 00 attached to the suction drum (6) is
The cutting edge may be fixed so as to protrude from the curved surface by a length approximately corresponding to the thickness of the film.

This way, after wrapping the film around the container,
The film can be cut by pressing the overlapping part of the film against the cutting edge with moderate force.

Furthermore, as an alternative method for cutting the film, as shown in FIG. The blade edge of the bill cutter 01 is suctioned at regular intervals under the rotation of the roll.
) It may be cut to the required length by pressing it against the peripheral film (g).

In the present invention, since the unit labels are cut out from the long film so that each of the adhesive layers repeatedly applied to the long labels is divided into two at intervals corresponding to the length of the unit labels, Each cut unit label has an adhesive layer on both ends, so if each unit label is cut from a long film and rolled onto a container, the adhesive layer will hold it in place. Can be attached in a tube shape.

According to the present invention, any position of various containers such as bottles and cans,
For example, even in areas where it is difficult to attach the film (g) in a tube shape, such as the tip of the bottle mouth (a) shown in Figure 10, the adhesive action of the adhesive layer prevents positional displacement. Can be accurately pasted into a tube shape.

Therefore, if this is sent to a heat shrinking process and subjected to heat shrinking treatment using hot air or the like, it can be finished in a mounting manner as shown in FIG. 12, which can be used as a cap seal to seal the mouth of the bottle in an attractive manner and reliably. Similarly, the desired mounting manner can be obtained for the flange portion of a container (b) having a flange (b.1) on the large surface of the container as shown in FIG. 11.

Furthermore, according to the present invention, there is no need to form the film into a tube in advance using seven-point sealing or the like as in the past, and the tube forming process is simplified because unit labels are cut out from a long film and wound as they are around the container. It is not necessary and is effective in simplifying the process and reducing the amount of fitting.

The present invention can be applied not only to attaching heat-shrinkable labels, but also to attaching non-heat-shrinkable labels such as plastic, tick film, or paper to the neck or body of containers. Needless to say, the present invention is not limited to tubular labels, but can also be applied to the case of attaching a one-point tank label to the body of a bottle or can.
