Description

The present invention relates to bottles to which tack labels are affixed and tack label affixing techniques, and more particularly to bottles affixed with longer tack labels than usual and a method for continuously affixing long tack labels.

BACKGROUND ART Containers (bottles in a broad sense) that are mainly filled with liquid and distributed on the market are known to have various external shapes, and cylindrical containers are often used for wine, beer, and other beverages.
Generally, a so-called label is affixed to the surface of these containers, which describes the product name and a description of the contents.

The majority of containers are made from plastics such as glass and PET. Generally, containers made of glass are called bottles.
Normally, labels that are attached to the surface of a bottle have a surface printed with the contents, product name, etc., and are attached to the surface of the bottle (such as the outside of the body) using an adhesive or adhesive applied to the back side. ing.

Labels are attached to the surface of bottles by hand in small quantities, but in order to attach labels to large quantities of bottles, an applicator called a "tack labeler" is used.
The tack labeler automatically attaches labels to the bottles that are continuously brought in by the bottle transport means and transports them to the next production line.
This tack labeler uses a tack label coated with an adhesive material, and as the tack label is fed out, it is brought into contact with the side of the body of the moving bottle (the surface of the bottle) and affixed.

A large number of these tack labels are wound into a drum and loaded into the application station of the tack labeler, and each time a bottle is transported and arrives at the application station, one tack label is fed out. ing.

FIG. 9 is a schematic diagram illustrating a general tack labeler using a rotary table as a bottle conveying means.
A plurality of bottle holders 10 (see FIG. 10) are provided at equal intervals on the rotary table 1, which is a bottle conveyance means, and the bottles 2 are placed one by one on the bottle holders 10. Rotate (hereinafter also referred to as revolution) in the direction of the bold arrow. Note that the bottle holder 10 constitutes a part of the rotation mechanism of the bottle 2.

The bottles 2 to be labeled are carried in by the loading means (star wheel) 300 on the carrying conveyor 31 of the bottle supply mechanism 3 and placed on the rotary table 1 one after another.
When the bottle 2 arrives at the applicator station 100 to attach the tack label 83 due to the revolution of the rotary table 1, the tack label 83 whose tip has been peeled off from the mount 82 sticks to the surface (outer surface of the body) of the bottle 2. After the bottle 2 is completely peeled off from the mount 82 (hereinafter referred to as rotation), the tack label 83 wraps around the body of the bottle 2.

Generally, after the bottle 2 arrives at the sticking station 100, it starts rotating and the tack label 83 is wrapped around it, and when it passes through the sticking station 200, it is stroked to ensure that it is stuck.
The sticking station 200 is a pressing mechanism composed of a slippery wall, a roll belt, a roller, or the like, and slides or presses the tack label 83 onto the body of the bottle 2 to ensure the attachment.
The bottle 2 (already pasted) that has passed through the sticking station 200 stops rotating, reaches the unloading means 400 by revolution of the rotary table 1, and is delivered to a bottle discharging mechanism (unloading mechanism) 4 such as a conveyor 41.

FIG. 10 is a diagram illustrating a bottle holder of the rotary table of the tack labeler in FIG. 9 and an example of the arrangement dimensions of bottles placed on the bottle holder.
This rotary table 1 is composed of 12 bottle holders 10 (small circles), and the arrangement pitch of the bottle holders 10 is 30 degrees.
In the figure, α represents the revolution diameter of the rotary table 1 on which the bottle 2 is placed and rotates, and β represents the diameter of a circle formed by adding the body diameter of the bottle 2 to the revolution diameter α.

In the pasting operation of the tack label 83 in the tack labeler, it is necessary to complete feeding out the tack label 83 by the time the next bottle 2 arrives at the pasting position of the pasting station 100. Therefore, in FIG. 10, β is the diameter. The length La corresponding to 1/12 (30°) of the circumference of the circle is the length of the label that can normally be accommodated.

In the case of a label length that can normally be handled, the tack labeler does not rotate the bottle 2 until the mount 82 (adhesive layer protective film) is completely peeled off from the tack label 83. Further, the feeding speed of the tack label 83 is such that while the non-rotating bottle 2 moves 30 degrees on the rotary table 1, feeding is completed at the length La shown in FIG.
Then, after the tack label 83 is completely peeled off from the mount 82, the bottle 2 starts rotating and the tack label 83 is wrapped around it.

The above pasting method will be further explained using FIG. 11. FIG. 11 is an explanatory diagram of the tack label pasting process in the prior art described in FIG. 9, and is a schematic diagram in which only the pasting station 100 and sticking station 200 in FIG. 9 are extracted.

First, just before the bottle 2 arrives at the affixing station 100, the mount peeling device 9 peels off the mount 82 from the tip of the tack label 83 of the tack label body 8, and leaves the tack label 82 on standby with its adhesive surface pointing out. The label body 8 is fed out at high speed)...(a)

The surface of the bottle 2 initially sticks to the adhesive surface of the tack label 83 that has been indexed (the bottle 2 does not rotate)...(b)

The tack label 83 is sent out in accordance with the revolution speed of the rotary table 1 (it is completely peeled off from the mount 82 while being dragged by the movement of the bottle 2)...(c)

Then, the bottle 2 starts rotating on its own axis by the bottle holder 10, and the tack label 83 is rolled up between the outer surface (surface) of the body and the sticking station 200 and is further pasted by sliding/pressing it... (d)

The tack label 83 is completely affixed to the outer surface of the body of the bottle 2, and its rotation stops when it passes the sticking station 200...(e)

In the above steps (a) to (e) for attaching a tack label, there is no problem when wrapping the tack label 83 with a length within the length La shown in FIG. 10, but when wrapping the tack label 83 with a length exceeding La It is not possible to attach the label spirally to the outer surface of the body of the bottle 2, which poses a problem when attaching a long label.

SUMMARY OF THE INVENTION An object of the present invention is to provide a bottle to which a long tack label is attached, which has a wrapping length exceeding the circumference of the body of the bottle, and a method for wrapping and affixing the tack label, which can solve the above-mentioned problems in the prior art. do.

(4) The base material layer having a high shape retention ability is made of a highly rigid material, and the total thickness of the tack label 83 is approximately 90 to 120 μm.

(5) The tack label affixing method according to the present invention is a method of affixing the tack label 83 in a spiral manner along the axial surface (outer surface of the body) of the bottle 2 that is conveyed to the affixing station 100 through a conveying means. There it is,
The tack label 83 has a wrapping length that exceeds the circumference of the body of the bottle 2, and the tack label 83 is pasted in a spiral along the axial direction of the bottle 2 by sequentially going through the following steps A to E. do.
Step A: Before the bottle 2 is transported by the transport means and arrives at the pasting station 100, the bottle 2 starts to rotate at a first rotation speed.
Step B: Immediately before the bottle 2 arrives at the pasting station 100, the predicted position of tapping the tip 84 of the tack label 83 exposed by peeling off the front area of the mount 82 (release film) that protects the adhesive layer 836. Take it out.
Step C: After the tip 84 of the tack label 83 comes into contact with the surface of the bottle 2, it is transported by the transport means and the bottle 2 is rotated at a second rotation speed that is slightly slower than the first rotation speed.

It goes without saying that the present invention is not limited to the configurations described above and the configurations described in the embodiments described later, and that various changes can be made within the scope of the technical idea of the present invention.

According to the tack label affixed bottle of the present invention, a long tack label is affixed in a spiral around the outer surface of the body of the bottle, so the tack label affixed bottle has a high design and expands various decorative possibilities. Can be provided.
Furthermore, by constructing the tack-labeled bottle of the present invention as a cylindrical bottle, the design of the long tack label that is affixed in a spiral manner is enhanced and enhanced, and the overall design of the bottle is improved. can do. It also has the effect of being easy to stick.
Furthermore, if the long tack label has not only a front surface printing layer but also a back printing layer, the back printing surface of the long tack label will be visible when attached to a transparent or translucent bottle. , it is possible to increase the amount of decoration and information, have a high visual effect, attract the interest of the person holding it, and create a bottle with a tack label that has an excellent design.

The tack label affixed to the tack label affixed bottle according to the present invention uses PET, OPP, etc., which has relatively high shape retention ability, as a base material having a surface printing layer, or a surface printing layer and a back printing layer, and is tacked. By configuring the entire thickness of the label 83 to be about 90 μm or more, preferably about 90 to 120 μm, the rigidity (shape retention ability) of the tack label after the backing paper (release film) is peeled off is increased, and the bending after the backing paper is peeled off is increased. occurrence has been significantly reduced.
Further, the tack label can avoid breakage even if the tension increases to some extent due to rotational fluctuations of the bottle.
Furthermore, since the tack label affixed to the tack label affixed bottle according to the present invention is thicker than those conventionally used, when a bottle to which this tack label is affixed spirally is gripped, the thickness of the tack label will be reduced. The unevenness makes it easier to grip and harder to drop.

As the bottle approaches the applicator station, it begins to rotate at a high first rotational speed. In the initial stage of positioning the tip of the tack label, high-speed feeding is performed in accordance with the rotation speed of the bottle.
From the start of tacking at the tip of the tack label, the bottle enters the sticking station, and when the front part of the tack label is firmly attached, the rotation speed of the bottle is reduced and the subsequent part of the tack label is moved to the second rotation speed. Paste.
By controlling the rotation speed of the bottle in this manner, it is possible to prevent the tack label from bending, tearing, or twisting when applying the long tack label in a spiral manner, thereby allowing accurate labeling work.

According to the present invention, a long tack label, which is required, can be reliably wound and stuck in a spiral around the outer surface of the body of various bottles.

Hereinafter, embodiments of the present invention will be described in detail with reference to drawings of examples.

FIG. 1 is a schematic diagram illustrating Embodiment 1 of a tack labeling device (tack labeler) for affixing tack labels to tack labeled bottles according to the present invention. (Hereinafter, it will be explained as a rotary table 1).

Further, 100 is a pasting station, 200 is a sticking station, 300 is a loading means, and 400 is an unloading means. 1A is a bottle conveying means speed sensor, 2A is a bottle proximity sensor, 3A is a bottle loading sensor, 4A is a bottle ejection sensor, 5A is an autorotation speed sensor, 7A is a mount sensor, and 8A is a tack label tip sensor.

In the pasting device shown in FIG. 1, the bottles 2 are sequentially placed one by one on the bottle holder 10 of the rotary table 1 in a loading means 300 by a bottle supply mechanism 3 constituted by a roller conveyor.
The rotary table 1 rotates (revolutions) at a set constant speed by a rotary table drive device 51. The rotary table driving device 51 is controlled so that the revolution speed of the rotary table 1 is detected by the bottle conveying means speed sensor 1A and always rotates at a constant speed.
The bottle 2 is conveyed by the revolution of the rotary table 1 and approaches the pasting station 100 .
Then, before the bottle 2 arrives at the pasting station, the bottle holder 10 on which the bottle 2 is placed starts to rotate, causing the bottle 2 to rotate at a first rotational speed.
This rotation is performed by the bottle rotation drive device 52 using detection signals from the bottle proximity sensor 2A and rotation speed sensor 5A.

At the pasting station 100, the tack label body 8 discharged from the tack label delivery device 6 is sent to a liner peeling device 9 having a peeling edge 91.
The leading portion (leader) of the mount 82 is folded back at the peeling edge 91 and rolled up by the mount recovery device 7 . The liner peeling device 9 peels off the front area of the liner 82 that protects the adhesive layer of the tack label 83 from the tack label 83 and exposes the front area of the liner 82 that protects the adhesive layer of the tack label 83 immediately before the bottle 2 arrives at the pasting station. 84 to the predicted tapping position.

The liner peeling edge drive device 92 adjusts the feeding position of the tack label body 8 based on the detection signals of the liner sensor 7A and the tack label tip sensor 8A, and controls the tack label body 8 to be tapped correctly on the outer surface of the body of the bottle 2.
The tack label body 8 is fed out by a delivery drive device 61, and the backing paper recovery device 7 is fed out by a recovery drive device 71. The feeding angle θ1 of the tack label body 8 to the application station 100 and the recovery angle θ2 of the mount 82 are set according to the rigidity, thickness, and other physical characteristics of the tack label body 8 to be used. Furthermore, the position d of the peeling edge 91 is also variable (double-headed arrow).

The tack label 83 that is rolled up and pasted at the pasting station 100 is pasted by sliding at the sticking station 200.
The sticking station 200 is not limited to the illustrated mechanism that presses a belt against the bottle 2 with a force F, but may also be a roller or a simple sliding wall.

After the tack label 83 is attached and the bottle 2 passes through the sticking station 200, the bottle 2 stops rotating, reaches the unloading means 400 by rotation of the rotary table 1, and is discharged (carried out) to the bottle discharge mechanism 4.

FIG. 3 is an explanatory diagram of a process of spirally pasting a long tack label, and is a diagram illustrating a series of steps of winding and pasting a long tack label around the outer surface of the body of the bottle 2.

First, before arriving at the applicator station 100, the bottle 2 starts rotating at a first rotational speed (high speed: relative value). Immediately before the bottle 2 arrives at the applicator station 100, the liner peeling device 9 peels off the tip 84 of the tack label 83 from the liner 82 to expose its adhesive surface. ...(A)

The tip 84 of the tack label 83 peeled off from the mount 82 is fed out in the direction of the passing path of the bottle 2 at a speed that is synchronized with the first rotation speed (tangential speed of the circumferential rotation speed) of the bottle 2. Then, the tip 84 of the tack label 83 comes into contact with the surface (outer surface of the body) of the bottle 2 and initially adheres (the circumferential speed of the bottle 2 and the feeding speed of the tack label 83 are the same). ...(B)

Next, when the tip 84 of the tack label 83 comes into contact with the surface of the bottle 2 and the tip 84 is firmly attached, the rotation speed of the bottle 2 is changed to a second rotation speed (relative value) that is slower than the first rotation speed. ).
At the same time, the feeding speed of the tack label 83 is reduced to a speed synchronized with the second rotation speed.

Furthermore, while the mount 82 in the rear region of the tack label 83 is peeled off as the bottle 2 is transported, the tack label 83 is wrapped around and attached to the axial surface of the bottle 2 rotating at the second rotational speed... C)
While further wrapping the tack label 83, the bottle 2 is firmly affixed by passing between the pressing member or the sliding member of the sticking station 200 at the sticking station 200 by the transport movement of the transport means. ...(D)
In this way, the entire tack label 83 is spirally wound and affixed to the surface of the bottle 2. After that, when the bottle 2 passes through the sticking station 200, the rotation of the bottle 2 stops, and then it is discharged from the conveying means...(E)

By sequentially performing steps A to E, the tack label 83 can be reliably attached in a spiral along the axial direction of the bottle 2.

FIG. 4 is a diagram illustrating the relationship between the amount of feed and the amount of pasting and winding of the tack label at the pasting station, comparing (a) a regular label and (b) a long label. As mentioned above, (a) a normal label is a label having a wrapping length less than the circumference size (around the body) of the outer surface of the body of a general bottle 2, and (b) a long label is a label according to the present invention. A tack label 83 is affixed to a tack label affixed bottle, and has a wrapping length that exceeds the circumference of the body of the bottle 2. Here, they are referred to as a "regular label" and a "long label", respectively.

In FIGS. 4A and 4B, the horizontal axis shows time (relative value), and the vertical axis shows label feeding length and label winding length (relative value).
In the figures (a) and (b), the broken line shows the label feeding length, and the solid line shows the label wrapping length around the body of the bottle 2.
In the case of the regular label shown in FIG. 2(a), during the initial label attachment period, after the tip 84 of the tack label 83 is attached to the bottle 2, the bottle 2 does not rotate and the label is further fed out, and the tack label 83 is After being completely peeled off from the backing paper, the bottle 2 starts rotating (rotation), and the label is wound up and pasted by the rotation, so that the length of the wrapping of the label increases from the middle.

In FIG. 4(b), while feeding out the label, at the same time, the bottle 2 wraps the tack label 83 at a high first rotational speed from the time of initial attachment of the label at the same speed as the feeding speed of the label. The length and wrap length increase at an equal slope. After the set period has elapsed, the rotational speed of the bottle 2 is reduced to the second rotational speed, and the label feeding speed is lowered accordingly (the slope of the label feeding amount changes). Thereafter, the long tack label 83 is spirally wound and pasted while maintaining the label feed speed so as to correspond to the second rotation speed. Once the entire length has been wrapped, the rotation of the bottle 2 is stopped.

In this way, when attaching the long tack label 83 to the bottle 2, the tack label 83 always follows the rotation of the bottle 2 during the entire period of spiral wrapping and attachment from the time when the tip 84 of the tack label 83 is tacked. .

FIG. 5 is a diagram illustrating the relationship between the rotational speed of a bottle when a tack label is attached at an attaching station, comparing (a) a regular label and (b) a long label.
Again, similar to FIG. 4, (a) the regular label has a wrap length less than the circumference of the outer body of bottle 2, and (b) the long label has a wrap length that exceeds the circumference of the body of bottle 2. It's a label.

The rotational speed (autorotation speed) of bottle 2 shown by the broken line is 0 in the case of the regular label shown in FIG. It is. After the label is completely peeled off from the mount, it starts rotating at the first rotation speed. The first rotation speed is preset in consideration of conditions such as the characteristics of the adhesive, the rigidity of the tack label 83, and the circumferential speed of the bottle 2.
The bottle 2 continues to rotate (rotate) at the first rotation speed until the pasting is completed. Then, when the winding of the tack label 83 is completed, that is, when the bottle 2 passes through the sticking station 200, the rotation of the bottle 2 is stopped.

In FIG. 5(b), the bottle 2 is rotated at high speed (first rotational speed) before the initial attachment of the tack label 8, and the tack label 83 is wrapped around it, and the timing is set so that the tack label 83 is sufficiently attached to the surface of the bottle 2. After the specified period has elapsed (same as above, this is set in advance taking into account conditions such as the characteristics of the adhesive, the rigidity of the tack label 83, and the circumferential speed of the bottle 2), the rotation speed of the bottle 2 is The rotation speed is reduced to 2, and the long tack label 83 is spirally wound and pasted while maintaining the second rotation speed, which is slower than the first rotation speed.
Once the entire length has been wrapped and the bottle 2 passes through the sticking station 200, the rotation of the bottle 2 is stopped.
Similarly to the above, the second rotational speed is such that the tip 84 of the tack label 83 remains tapped on the outer surface of the body of the bottle 2, and the tack label 83 with the backing paper 82 in the rear region of the tack label 83 peeled off. The speed is set to apply tension at a level that does not cause deflection.
In this way, by rotating the bottle 2 at high speed at the time of initial attachment of the tack label 8, it is possible to bring the long tack label 83 into contact with the bottle 2 while maintaining the tension, and then by rotating at a low speed, The long tack label 83 is wound slowly and surely, and the long tack label 83, which is easily wrinkled, twisted, and misaligned and is difficult to handle, can be attached with high precision.
The first rotation speed and the second rotation speed are set in consideration of conditions such as the length of the tack label 83, the feeding angle, and the characteristics of the adhesive. A 40% deceleration allows stable and reliable attachment, and in addition to the above conditions, the speed is adjusted as appropriate depending on the material of the bottle 2, the rigidity of the tack label 83, etc.

In this way, when attaching a long tack label to the bottle 2 (FIG. 5(b)), the tip 84 of the tack label 83 is tacked to the outer surface of the body of the bottle 2 during the entire period of spiral wrapping and attachment. , the tack label body 8 always follows the rotation of the bottle 2. That is, the circumferential speed of the bottle 2 and the feeding speed of the tack label 83 are controlled to be the same.

This control is carried out by the bottle transport means (rotary table) speed sensor 1A, bottle proximity sensor 2A, rotation speed sensor 5A, mount sensor 7A, tack label tip sensor 8A, bottle transport drive device 11, rotary table drive device 51, bottle rotation It is controlled by a (rotation) drive device 52, a tack label delivery device 6, a mount collection device 7, and a mount peeling device 9.

The transport speed (revolution speed) of the bottle 2, the rotation speed and start of rotation of the bottle 2, the rotation speed and the switching timing between the first and second speeds, the feeding speed of the tack label body 8, the feeding angle θ1 of the tack label body 8, and Operating conditions such as the mount collection angle θ2 are calculated and controlled from data on the type of bottle 2 (body diameter size, surface characteristics) and characteristics such as the adhesive material characteristics and thickness of the tack label 83 used.

The bottle 2 with the tack label 83 affixed is discharged from the rotary table 1 by the bottle ejection mechanism 4, inspected to see if the tack label 83 has been affixed correctly, and sent to a subsequent shipping station (not shown). ).

Each of the bottle holders 10 on which the bottles 2 are placed is equipped with a separate bottle rotation device (not shown). Start and stop the rotation of each bottle rotation device.

Next, an example of the structure of the tack label attached to the tack label attached bottle according to the present invention will be explained.
FIG. 6 illustrates an example of a tack label attached to a tack label attached bottle according to the present invention. It is a top view of a state.
The tack label 83 has a length D to be spirally wrapped around an attachment area W (see FIG. 8) set on the body of the bottle 2, and is temporarily adhered to a mount 82 having a width corresponding to the attachment area W. ing. Note that the width of the mount 82 may be wider than H.
The length D of the tack label 83 is a length that covers the axial width label attachment area W of the bottle 2 with a specified number of turns, and in the present invention, the surface diameter of the bottle 2 is set to 1.0. , the length is approximately 1.0 times to 4.0 times longer. In particular, a length of about 1.5 to 2.5 times is preferable because it provides a bottle with a tack label that is excellent in design.

The size L of the mount 82 in the winding direction (the feeding direction of the tack label body 8 is the traveling direction S of the tack label body 8) is determined by the length of the tack label 83 that is spirally wound.
That is, the inclination angle φ of the tack label 83 temporarily attached to the mount 82 depends on the length D of the tack label 83.
The inclination angle φ is adjusted to an angle that allows the entire length D of the tack label 83 to be affixed to be wrapped within the axial width label affixing area W on the surface of the bottle 2. Therefore, the inclination angle φ of the tack label 83 temporarily attached to the mount 82 varies depending on the length D of the tack label 83. In this way, by adjusting the inclination angle φ, it is possible to attach a long tack label 83 to a predetermined bottle 2.
The interval T between the tack labels 83 on the mount 82 is set at the interval between the bottles 2 that are revolved and conveyed by the rotary table 1, and according to the specifications of the tack label body 8, the tack label sending device 6 (or the mount collecting device 7) ) corresponds to the sending amount (recovery amount) setting value.

The tack label 83 affixed to the tack label affixed bottle according to the present invention is composed of a base material layer having a high ability to maintain shape. Here, the ability to maintain shape refers to rigidity strength, and the tack label 83 has a thick base material layer made of a highly rigid material, thereby increasing the overall thickness and increasing the ability to maintain shape. .
In addition, the tack label 83 has a thickness that is rigid enough to suppress the occurrence of bending and wrinkles after the mount 82 is peeled off, and flexible enough to handle the tension when it is spirally pasted onto the bottle. It is composed of
For example, the base material layer is made of PET, OPP, etc., which have a relatively high shape retention ability, and the total thickness of the tack label 83 is 90 μm or more, preferably about 90 to 120 μm.
With the above configuration, even if the backing paper 82 is peeled off, the tack label 83 has a large rigidity and a high ability to maintain its shape, so that the occurrence of deflection after the backing paper 82 is peeled off can be significantly reduced.
Further, the tack label 83 having the above structure can avoid breakage even if the tension increases to some extent due to rotational fluctuations of the bottle.
Furthermore, since the tack label 83 is thicker than those conventionally used, when a bottle to which the tack label 83 is spirally attached is gripped, the unevenness of the thickness makes it easier to grip, and the bottle can be easily removed. It becomes difficult.

FIG. 7 is a schematic diagram illustrating an example of the structure of a tack label attached to a tack label attached bottle according to the present invention.
The tack label body 8 shown in the figure has a tack label 83 temporarily attached to a mount 82, is wound into a coil, and is loaded into a labeler (not shown).
As an example of the structure of the tack label body 8, the surface protection layer 831 is the top layer, and the bottom surface thereof includes a surface printing layer 832, a surface base material layer 833, a back surface printing layer 834, a back surface base material layer 835, and an adhesive layer ( It is constructed by laminating an adhesive material 836 (which is commonly used for bottles) and a mount 82, and has a total thickness of 90 μm or more, preferably about 90 to 120 μm or more.
The front base material layer and the back base material layer are films made of synthetic paper, synthetic resin, etc., and are made of materials that have strength and rigidity, as well as flexibility and stretchability to follow the shape of the outer surface of the bottle body. . Specifically, resins such as polyethylene terephthalate (PET), polypropylene (PP), polyvinyl chloride (PVC), polyethylene (PE), ABS, polycarbonate, and acrylic; paper base materials include high-quality cardboard, art cardboard, Examples include Japanese paper.
As the front base material layer, a PET film, particularly a silvery vapor-deposited PET film, is suitable, and as the back base material layer, a biaxially stretched polypropylene film is suitable.
The surface protective layer may be a transparent or translucent film such as polyethylene terephthalate (PET), polyester, polyvinyl chloride (PVC), polystyrene (PS), polypropylene (PP), polyethylene (PE), polylactic acid ( The film is made of a resin material selected from PLA) or cyclic olefin copolymer (COC), and transparent PET film is particularly suitable.
The tack label 83 having the above structure has the base material layer (front base material layer 833, back base material layer 835) with a large shape maintaining ability, and it is possible to attach a long tack label 83 without twisting or wrinkles. shall be.

The tack label 83 shown in FIG. 7 has a printed layer on the front and back sides, but it may have a printed layer on only one surface. In that case, there is no back printed layer 834, and therefore the back base material layer 835 is also unnecessary, and the adhesive layer 836 is directly applied to the back surface of the front base material layer 833. In this case, the surface base material layer 833 is made thicker to adjust the overall thickness.
In addition, in the case of the tack label 83 having the back side printing layer 834, the decorative characters and figures printed on the back side printing layer 834 can be seen through from the inner circumference side of the bottle 2 to which it is attached. The bottle comes with a tack label that allows you to increase the quantity.

FIG. 8 shows an example of a tack-labeled bottle to which a long tack label according to the present invention is affixed.
The bottle 20 with a tack label according to the present invention is preferably a cylindrical bottle, for example, a transparent or translucent cylindrical bottle called a wine bottle.As shown in FIG. One type has an appearance in which the tack label 83 is wrapped 1.5 times around the body (one and a half wraps around the body), and the other type has a tack label 83 wrapped 2.0 times around the outer surface of the body of the bottle 2 (as shown in Figure (b)). This shows the appearance of the fuselage (attached twice).
In the figure, the tack label affixed bottle 20 with 1.5 wraps of the tack label 83 and the tack label affixed bottle 20 with 2.0 wraps are shown; The length and width between labels can be adjusted accordingly. Further, the shape of the bottle 2 is not particularly limited, but a cylindrical shape is preferable because the design of the entire bottle 2 to which the elongated tack label 83 is attached can be enhanced.

The tack label 83 affixed to the tack label affixed bottle according to the present invention is long, and compared to general tack labels, wrinkles, twists, and misalignment are more likely to occur after the mount 82 is peeled off. As described in FIG. 7, by using a material with a high shape retention ability for the surface base layer 833, the occurrence of defects in the tack label 83 can be avoided even after the mount 82 is peeled off. This suppresses adhesion defects such as misalignment and wrinkles when adhering to the bottle 2. Note that the thickness of the surface base material layer 833 may be made thicker or thinner to such an extent that wrinkles or the like do not occur, depending on the characters, figures, images, etc. that are decorated on the tack label 83.
In addition, by making the front base material layer 833 and the back base material layer 835 of thick materials, when the tack label 83 is pasted on the bottle 2 in a spiral shape, spiral irregularities are generated on the surface of the bottle 2, and It is possible to construct a bottle with a tack label attached that is not difficult to hold and is easy to hold.

According to the tack label affixed bottle and tack label affixing method according to the present invention, the tack label 83 has a high ability to maintain its shape after the mount 82 is peeled off, and the occurrence of deflection after the mount 82 is peeled off is greatly reduced. Even if the tension on the tack label 83 changes somewhat due to rotational fluctuations of the bottle 2, problems such as poor adhesion and breakage due to sagging of the tack label 83 can be avoided.

In the present invention, the bottle 2 begins to rotate at a high first rotational speed upon approaching the applicator station 100. During the initial period when the tip 84 of the tack label 83 is positioned, high-speed feeding is performed in accordance with the rotation speed of the bottle 2 .
The bottle 2 enters the sticking station 200 from the start of tacking of the tip 84 of the tack label 83, and when the front side of the tack label 83 is securely affixed, the rotation speed of the bottle 2 is reduced to a second rotation speed. By pasting the subsequent portion of the tack label 83, it is possible to accurately paste it to the predetermined pasting area W.

As described above, according to the present invention, by controlling the unwinding speed of the tack label 83 and the rotation speed of the bottle 2, the bending and pulling of the tack label 83 when the long tack label 83 is applied in a spiral manner can be prevented. Cutting and twisting are prevented, allowing accurate labeling work.

In Embodiment 2, the present invention is applied to a rotary conveyor system as shown in Patent Document 1 instead of the rotary table in Embodiment 1 as a means for transporting bottles. The application station, sticking station, inspection station, and their auxiliary equipment are basically the same as those used in the above-described rotary table system, except for the mechanism for transporting the machine.
Furthermore, since there is no fundamental difference in the structure and the method of attaching the tack label attached to the tack label attached bottle, a repeated explanation will not be given.
Of course, the same applies to bottles with tack labels attached by the above method.

Also in the second embodiment, by controlling the feeding speed of the tack label 83 and the rotation speed of the bottle, it is possible to prevent the tack label from bending, tearing, or twisting when the long tack label 83 is spirally wrapped and pasted, and to ensure accurate Can perform label pasting work.

In Example 2, by controlling the unwinding speed of the tack label and the rotation speed of the bottle, it is possible to prevent the tack label from bending, tearing, or twisting when attaching a long tack label in a spiral manner, thereby producing accurate labels. Can perform pasting work.

The present invention is not limited to the tack label 83 having a wrap length of more than 1.0 to 2.0 wraps on the bottle 2 described in each of the above embodiments, but is also applicable to the tack label 83 having a wrap length longer than that. can.
