Description

Easily removable label and its manufacturing unit {A LABEL BEING TAKEN OFF EASILY AND THE METHOD THEREOF}

The present invention relates to a label that can be easily removed and a manufacturing apparatus thereof, and more particularly, a label that is attached to the outer circumferential surface of a plastic container (PET or PE bottle) forms a cut line to facilitate removal, and is divided by the cut line. Tear tape (hereinafter referred to as "Tear Tape") is attached to the inner surface of the removal area to be removed, and a predetermined cutting groove is formed on the upper or lower portion of the cutting line to have a handle function when cutting. When the label is attached to the plastic bottle in the state that it is contracted by the heat compression contraction method on the outer surface of the plastic bottle, the incised handle portion protrudes on the outer surface of the container in the form of a mountain, so that the label can be removed and facilitated. The present invention relates to a label that can be easily removed for recycling and a manufacturing apparatus thereof.

In general, attachments such as trademarks used in plastic bottles are generally trademarks, ingredients, duration of use, manufacture and seller of polypropylene (OPP, POLY PROPYLERNE) or vinyl chromide (PVC) resin films. Printing, etc., by moving the process and continuously bonding the both ends to form a cylindrical shape and wound in a roll shape, and then moved to a container manufacturing plant, polypropylene, that is, OPP is put on a PET bottle and bonded with an adhesive, PVC is formed by attaching it to the container by heat compression shrinkage.

The polypropylene resin film in the above, due to the material properties, it is impossible to attach by thermal pressure shrinkage method, and always adopts an attachment method attached by an adhesive.

Conventionally, the PET container was used after packaging and circulating the contents of a beverage, such as a beverage, and discarded because it was not intended for reuse, and only a small amount was recycled through a high-temperature treatment process.

Although the PET container is a high quality recycled resource, it is wasted because it is wasted, but the waste of resources is caused, the material properties and volume is difficult to landfill, and if left unattended, it causes a problem of environmental pollution.

Therefore, in recent years, the handling problem of PET bottles has emerged as a problem to be solved, and in response to the trend of resource recycling, waste PET bottles are collected and recycled as high-quality materials for manufacturing high bars.

The above PET bottle is not reused by maintaining its form, but is collected and crushed and washed to a certain amount to be reused as a raw material for a completely different purpose such as a high bar as described above.

However, the PET bottle is made of polyester resin while the label is a polypropylene (OPP,) or polyvinyl chloride (PVC) resin film, so the PET bottle must be separated when reused. It is inevitable.

Conventionally, in the case of separating the PET bottle and the resin film attached to the outer surface of the PET bottle, that is, the label (for example, in the case of PVC), since the specific gravity of the PET bottle and the label is the same, separation by the specific gravity separation method is impossible. In addition, as described above, when the material is polypropylene (OPP), since the label is attached to the outer surface of the PET bottle by the adhesive completely, it is very difficult to remove it. Due to excessive consumption such as working time and labor costs, it was impossible to rely on it, so it was not feasible in terms of container recycling.

In addition, since the vinyl chloride (PVC) material label does not have a structure that is easy to remove, it is difficult and difficult to separate and remove it from the outer surface of a PET bottle. If the same is mixed with the recycled material and washed as it is, the material to be recycled will contain foreign matters, and the quality of the material will be degraded. There is a fatal problem that makes it impossible to recycle.

In order to overcome these drawbacks in recent years, polystyrene (OPS) or polyethylene resin film, which is lighter than the PET bottle, has been used as an adhesive, that is, a label.

Since the polystyrene resin film has a smaller specific gravity and a higher heat shrinkage rate than the conventional polyvinyl chloride resin film, it is formed in a roll form by printing and bonding as described above, and then moved to a container factory to maintain a cylindrical shape. The label is attached to the outer surface of the PET bottle as a series of work processes are continuously carried out while being cut and inserted into the outer surface of the container while being cut together and adhered by being compressed and compressed by the thermal compression contracting method. The resin film is attached by spreading it on the outer surface of the container using elasticity.

The label (PVC) attached by the thermal pressure bonding method is deformed into a contracted state by heat, and thus it is indented into the curved irregularities according to the shape of the various containers and pressed to maintain the shape of the container. This will produce a natural label on your back.

However, while the label attached to the container has a beautiful effect such as giving a sense of unity with the outer surface of the container, when the label is separated to reuse the PET bottle, the specific gravity is separated, but the specific gravity is the same. The problem still remains that the separation of the bottle is not good and the foreign matter such as label residue penetrates into the crushed PET bottle recycled to stabilize the quality of the resource.

In addition, when the above specific gravity separation method is used, problems such as problems in profitability of the recycling side are also inherent.

Since the label in the above is in close contact with the outer surface of the PET bottle in the form of shrinkage by the heat compression shrinkage method, it is very difficult for the user to remove it manually, and the use of a separate tool requires excessive labor and labor costs. 'S spending was so severe that they eventually faced unrealizable problems.

Thus, the present inventors have developed a technology that allows the label to be easily removed from the outer surface of the container by forming a perforation line on the label to solve the above problems and secure high quality recycling resources. The application is disclosed in 14183.

The applicant's prior design makes it possible by inducing a separate collection by promoting the disposal by forming a removal area by forming a perforation line on the label to facilitate and accelerate the reuse of the PET container and to provide high-quality recycled resources. I'm doing it forever,

Since the preliminary proposal only forms a perforation line on one side of the label, it is not easy to cut the opening of the cut start portion, which is easily given up because the container user who wants to remove the label is not easy to remove the label. In order to do this, it was impossible to completely separate without using a separate aid such as a knife.

As a result, the present applicant's prior design is difficult to completely remove the label from the container, and since the label is not easy to remove, there is a problem inherent in achieving a purpose.

The present invention has been made in order to fundamentally solve the problems of the prior art as described above and all the problems of the applicant's prior design, and has the following objects.

The main object of the present invention is to make it easy to remove the label attached to the outer peripheral surface of the PET bottle easy to remove the label for recycling the PET bottle.

Another object of the present invention is to provide a high-quality recycled resources by fundamentally preventing the inflow of foreign substances when recycling PET bottles by leaving the label completely removed from the outer surface of the PET bottle by the structure that is easy to remove. .

In order to achieve the above object, in the present invention, a perforation line is formed on one side of the label, and at the same time, the tearing line is improved through a tear tape on an inner surface of the removal area partitioned by the perforation line, and the tear line has a handle function when cutting. When a label is attached to the plastic bottle in a state of being contracted by a heat compression contraction method on the outer surface of the plastic bottle by forming a cut groove of a certain shape, the cut handle portion protrudes on the outer surface of the container in the form of a mountain and is formed. It was possible to make the removal operation more desired and easier, and it will become more apparent if this is explained in more detail based on the accompanying drawings.

That is, the present invention as shown in the accompanying drawings, Figures 2 to 5,

In the conventional label (1) consisting of a thin plate material such as PVC, OPS, or polyetherylene resin film attached by elasticity to shrink on the outer surface of the PET bottle 10 by a heat compression shrinkage method,

On one side of the label 1, a set of cutout lines 11 are formed in the vertical direction by maintaining a predetermined interval to form a removal region 1 ',

On the inner surface of the removal region 1 ', a conventional tear tape 12 having a width smaller than the width of the removal region 1' is attached and interposed.

At this time, a predetermined length of cutout grooves 13 are formed at the upper end of the set of cutout lines 11 that divide the removal area 1 'of the label 1, so that the label 1 is attached to the PET bottle 10. In this case, the upper end of the removal area 1 ′ due to the contraction and adhesion of the label 1 may protrude to the outer surface of the PET bottle 10 to constitute the handle 14,

In addition, according to the embodiment, the tear tape 12 may be attached and interposed therebetween without forming the cutting line 11 and forming only the cutting grooves 13 on both sides of the upper end of one side.

In the present invention, the removal area 1 of the label 1 is formed by the formation of the removal area 1 'by the formation of the perforated line 11 and the tear tape 12 interposed on the inner surface of the removal area 1'. ') Is pulled from the top to the bottom or from the bottom to the top with a slight force, the removal area (1') is easily separated from the label (1) and the heat compression contraction on the outer surface of the PET bottle (10) The label attached by the method and the polyethylene label 1 attached by the elasticity have an effective effect of being easily removed.

Particularly, the cutting groove 13 formed at the upper end of the cutting line 11 receives heat when both sides of the cutting groove 13 are attached to the outer surface of the PET bottle 10 in a contracted state by a heat compression contraction method. When it is contracted, it is deformed and the PE is fixed by wrapping the label on the outer surface of the container while opening the label by elasticity. In this case, the handle 14 is formed by the elasticity and shrinkage property. It is naturally formed in the shape and protrudes in the form of flapping on the outer surface of the PET bottle 10, so that it is easier to separate the removal area 1 'from the label 1, and thus attached to the outer surface of the PET bottle 10. The stripping action of the label 1 becomes even more desirable (see FIGS. 5A and 5B).

The following is a preferred example of the apparatus of the present invention which enables the attachment and interposition of the cutting line 11 and the cutting groove 13 and the tear tape 12 formed on the label 1 of the present invention as described above. Let's take a look at the details.

That is, the device of the present invention is as shown in the accompanying drawings, Figures 6-9,

Winding means (2) for winding the printed polyethylene resin film (F) in the winding roller, adhesive applying means (4) for applying an adhesive to one end of the processed film (F), and the transfer position of the film (F) Positioning means (6) for detecting and adjusting the position, and the adhesive means for continuous production of a cylindrical semi-finished attachment by adhering one end of the one side, the adhesive is applied to the film (F) to the other end of the back side (7) and a label production apparatus comprising a combination of winding means (8) such as a roller for winding a film (F) bonded in a cylindrical shape.

Tear tape wound in the shape of a roll controlled by the transfer position detecting means 6 so as to be located on one inner surface when the film F is cylindrically bonded by the bonding means 7 to the upper portion of the transfer position detecting means 6. 12 is installed to be continuously supplied by the tier tape supply means 20,

A tear tape 12 interposed between the adhesive means 7 and the winding means 8 for winding the film F adhered by the adhesive means 7 to one end of the inner surface of the film F. A cutting roller 30 is formed on the inner side of the cutting line 11 to form the cutting line 11 while the upper and lower surfaces of the film F are in contact with the roller.

The rear end of the cutting roller 30 is made of a cutting groove forming part 40,

The cutting groove forming part 40 is fixed to the holding roller 43 and the support 44 in which the cutting rollers 42 in which a plurality of cutting blades 41 are spaced apart at regular intervals on one side of the outer surface thereof are located at the bottom thereof. With the upper and lower clearance adjustable,

On one side of the support 44, a position detecting sensor 45 is installed so that the cutting roller 41 always matches the cutting groove 13 forming part of the film F forming the label 1 with the cutting roller 42. It is configured to control the number of revolutions.

The above-described cutting groove forming unit 40 is configured to be connected to the labeling device of the label 1, that is, the film F, in consideration of its workability and productivity, so that the continuous work can be made, but if necessary, it is separated separately. The above cutting groove 13 may be formed in the post-treatment step.

At this time, the device necessary for forming the cutting groove 13 is the same as that of the above-described invention device or can be easily modified to achieve this, but is not particularly limited, but a plurality of cutting blades protruding on one side of the outer surface of the cutting roller 42 The objective of the present invention is to be achieved only by adjusting the number of revolutions of the 41 and the lower roller to an optimal state and exactly matching the formation position of the cutout groove 13 using the position sensor 45 or the like. Will be achieved.

As the reference numeral 3, processing means for roughly processing one end of one side of the film (F), 4 'is an adhesive applying means that may be installed and used on the adhesive means 7 of the film according to the embodiment, 5 The drying means for drying the adhesive to hot air at a constant temperature, 46, 47 is the winding roller mounted on the front and rear of the cutting groove forming portion 40, 48 is the label of the cutting groove forming portion 40, that is, the film ( Each drive roller which moves while pressing F) is shown.

The operation of the present invention as described above is as follows.

First, the cutting line 11 forming operation of the present invention and the technique of interposing the tear tape 12 may use a conventional apparatus for bonding existing labels.

A conventional bonding apparatus of such a label will be described by taking an example of a "both end bonding apparatus for polyethylene bottle films for plastic bottles" disclosed in Korean Patent Application No. 98-56857 filed by the applicant.

However, the above-mentioned label of the present invention does not necessarily mean that it is limited to the device of the present invention.

In order to manufacture the present invention, that is, the label 1, the film (F, PVC, OPS, PE, etc.) is applied to the film and wound in the form of a roll, and the roll is completed and wound the roll winding the device of the present invention Wind up in (2).

After unwinding one end of the roll rolled on the winding means (2) so as to proceed smoothly to the respective means of the device and applying power to the control system to give an operation command to the film (F) While the pneumatic cylinder is controlled by receiving a signal according to the detection of the transfer position detecting means 6, one end of the one side of the one side on which the adhesive is applied is bonded to the other end of the printed film F, and is continuously processed into a cylindrical semi-processed attachment. I'm going to

At this time, the tear tape 12 is uniformly continuously fed before the process of adhering the film F to the cylinder F by the tear tape supply means 20 and attached to one inner surface of the film F bonded to the cylindrical shape. To maintain state.

With this semi-finished attachment, that is, the film F attached in a cylindrical shape, the cutting roller 30 positioned at the upper side of the semi-finished attachment is abutted on the film F passing between the lower interlocking rollers. While rotating in a state to form a cut line 11 in the film (F),

At this time, the cutting roller 30 forms a single cutting line 11 in the form of pressing on the upper surface of the film F attached in a cylindrical shape, and thus, on both sides of the overlapping film F, that is, the upper and lower portions. At the same time, the same cutting line 11 is formed to partition the removal region 1 '.

Of course, the tear tape 12 is located in the removal region 1 '.

In this state, when the forming of the removal area 1 ′ is completed by attaching, interposing, and forming the cutting line 11 in the state of the tear tape 12, the cutting groove forming part 40 installed in connection with the rear end of the process is moved. Will be moved to.

In the cutting groove forming part 40, a plurality of cutting blades 41 spaced at regular intervals on one side of the outer surface are installed at equal intervals, and the cutting blades of the cutting rollers 42 having the position sensor 45 are installed ( 41) the cutting groove forming portion of the label 1, that is, cylindrically bonded, so that the cutting blade is positioned between each cutting portion where the ends of the printing portion are interconnected to form the cutting groove 13.

The forming operation of the cutting groove 13 is formed at the upper end of the pre-formed cutting line 11 or is formed at the lower end.

Apparatus for forming the cutting groove 13 in the above can be used by applying a conventional cutter.

However, the cutting groove 13 in the above-described label and the label on which one side of the film F, that is, the cutting line 11, which is traveling between the pressing roller 43 and the cutting roller 42 at a constant speed are formed. By forming exactly one in the upper portion of the adjacent portion is formed at the same time on the upper and lower surfaces of the overlapping film (F) paper.

This determination of the correct position can be controlled by adjusting the rotational speed of the motor to the position sensor (45).

In the above process, the cutting groove 13 and the tear tape 12 are formed by forming the cutting groove 13 at the same position even in the case of the label 1 having only the tear tape 12 attached thereto without the cutting line 11 being formed. It is possible to separate the label (1) by this, thereby enabling the removal operation of the label (1) attached to the outer surface of the PET bottle (10).

When the forming operation of the cutting groove 13 is completed by the apparatus as described above, it is wound by a winding means 47 such as a roller and moved to the manufacturing plant of the PET bottle 10.

The moved label 1 may be attached to the outer surface of the PET bottle 10 by the cutting that is usually performed and also by the heat compression shrinkage method and the elastic attachment method.

At this time, the label 1 is contracted to the outer surface of the PET bottle 10 and the state in which the upper end of the removal region 1 ′ by the cutting groove 13 naturally spreads on the outer surface of the container while being attached by the elastic attachment method. Is protruded to be configured to perform the handle (14) function when removing the label (1).

The above-mentioned label (1) is used for packaging bottles such as drinks, such as PET bottle 10, after the drink user grasps the handle 14 formed by the cutting groove 13 to apply a slight force When it is lowered to the lower side, since the tear tape 12 is attached to the inner surface of the removal area 1 ', the removal area 1' is easily removed along the perforation line 11 by the tear tape 12.

In this state, the label 1 attached by the heat compression shrinkage method and the elastic adhesion method is easily removed from the outer surface of the PET bottle 10 without any foreign matter such as an adhesive, and thus is a high quality recycling resource. Only PET bottle 10 can be easily collected.

According to the present invention, the label attached to the outer circumferential surface of the PET bottle can be easily removed so that the label can be easily and quickly removed for recycling the PET bottle, and the label is removed from the outer surface of the PET bottle. It is obvious that it is a very advantageous invention that can simultaneously achieve various useful effects such as being able to provide high quality recycled resources by fundamentally preventing foreign substances from being introduced when PET bottles are recycled by completely separating and removing residues without leaving residues.
