Description

[Technical Field]

[0001] The present invention relates to a label winding and a label dispensing device. [Background technology]

[0002] A label roll, formed by winding a continuous label onto a core material such as a paper tube, is used by being mounted on the dispensing device of a label application machine. The continuous label is a strip-shaped body in which multiple labels are attached at predetermined intervals to one side of a strip-shaped separator.

[0003] Here, in order to increase the length of the label continuum wound around each label roll and reduce the number of times the label rolls are set in the dispensing device, thereby improving work efficiency, a traverse-wound label roll has been considered (see, for example, Patent Document 1). A traverse-wound label roll is manufactured by using a core material whose axial length is longer than the width of the separator, and winding the label continuum around the core material while moving the label continuum back and forth (traversing) in the axial direction relative to the core material. [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2003-104594 [Overview of the project] [Problems that the invention aims to solve]

[0005] However, in traverse winding, bending deformation (torsional deformation) is imparted to the label continuum. In particular, significant bending deformation is imparted to the turn portion of the traverse (the reciprocating folding portion located near both ends of the core material in the axial direction). This bending deformation caused by traverse winding can result in deformations such as wavy or wrinkled surfaces in the label continuum. Label continuums using standard paper separators are highly rigid and resistant to stretching, thus they do not deform. This can lead to lifting or creasing. Label continuums with lifting or creasing may malfunction when fed through a labeling machine (labeler).

[0006] Furthermore, if the labels are wound with low tension to prevent bending and deformation, then when the label roll is stored or transported, if the tension applied to the label continuum is low, the label continuum may deform, such as becoming wavy or wrinkled, causing the winding to loosen and the roll to collapse, or creating gaps between the label continuums.

[0007] The object of the present invention is to provide a traverse-wound label body that can follow the bending deformation of a label continuum, making it difficult for gaps to form between labels and allowing it to be maintained stably. [Means for solving the problem]

[0008] The label winding of the present invention comprises a core material and a continuous strip of labels wound around the core material. The label continuum includes a strip-shaped separator and labels that are peelably attached to the separator. The label continuum is wound around the core material while the winding position of the label continuum is moved back and forth in the axial direction relative to the core material. The separator is made of resin. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide a traverse-wound label body that can follow the bending deformation of a label continuum, making it difficult for gaps to form between labels and allowing it to be maintained stably. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same parts or common parts are denoted by the same reference numerals.

[0012] In this specification, the "front surface" means the outer surface of the label attached to the container, and the "back surface" means the inner surface of the label attached to the container. The "axial direction" means the length direction of the core material, and the "circumferential direction" means the circumferential direction of a circle formed by the intersection of a virtual plane perpendicular to the axial direction of the core material and the outer peripheral surface of the core material. The transverse direction (TD) means the direction corresponding to the width direction (short side direction) of the belt-like body, and the longitudinal direction (MD: machine direction) means the direction corresponding to the length direction (long side direction) of the belt-like body.

[0013] <Label roll> Referring to FIGS. 1 and 2, the label roll 1 of the present embodiment includes a core material 3 and a belt-like label continuum 2 wound around the core material 3.

[0014] The label continuum 2 is wound around the core material 3 while relatively reciprocating the winding position of the label continuum 2 in the axial direction with respect to the core material 3. That is, the label continuum 2 is wound around the core material 3 in a traverse winding manner. As a method of reciprocally moving the winding position of the label continuum 2 in the axial direction relative to the core material 3, the core material may be reciprocally moved in the axial direction with the winding position of the label continuum fixed, or the winding position of the label continuum may be reciprocally moved in the axial direction of the core material with the core material fixed.

[0015] For the traverse-wound label winder 1, a core material 3 having an axial length longer than the width of the label continuum 2 (separator 21) is used. The axial length of the core material 3 is, for example, at least about 10 mm longer than the width of the label continuum 2, preferably 3 to 20 times the width of the label continuum 2. The specific axial length of the core material 3 is, for example, 150 mm to 300 mm. The core material 3 is a cylindrical or columnar member, such as a paper tube, a plastic tube, a resin tube, etc. The core material 3 has an inner diameter of, for example, 3 inches, 6 inches, etc., and has a thickness of 10 mm. Note that by rotating the core material 3 in the direction of the arrow shown in FIG. 1, the label continuum 2 can be wound.

[0016] By manufacturing the label winder 1 by traverse winding using a core material 3 having an axial length longer than the width of the label continuum 2, a label winder 1 around which a longer label continuum 2 is wound can be manufactured compared to a parallel-wound label winder. That is, the winding amount per core material can be increased. Thereby, when applied to a label affixing device, the number of times of mounting the label winder can be significantly reduced, and the workability of the label affixing device can be improved.

[0017] In the label winder 1, the ratio of the deviation width Z (see FIG. 4) of the label continuum 2 (separator 21) adjacent in the radial direction of the core material 3 (partially overlapping) to the entire width of the label continuum 2 (separator 21) is preferably 35% to 100%, more preferably 40% to 50%. Note that the deviation width Z corresponds to the axial movement distance (relative movement distance with respect to the core material 3) of the winding position per one turn in the circumferential direction of the core material 3 (every time the core material 3 rotates). When the deviation width Z is within such a range, a stable label winder 1 that is unlikely to cause winding collapse can be obtained. The ratio of the displacement Z may differ between the axial ends of the core material and the central part. For example, the ratio of the displacement Z around the axial ends of the core material may be less than the ratio of the displacement Z in the central part of the core material. By making the ratio of the displacement Z different between the axial ends of the core material and the central part in this way, collapse of the winding can be prevented.

[0018] Furthermore, in the label winding 1, the ratio of the overlap width W (see Figure 4) of the maximum thickness portion (label portion) of the label continuum 2 (separator 21) adjacent to the core material 3 in the radial direction to the overall width of the label continuum 2 (separator 21) is preferably 5 to 60%, and more preferably 45 to 55%. When the overlap width W is within this range, a stable label roll 1 that is less prone to unraveling can be obtained. The overlap width W ratio may differ between the axial ends of the core material and the central part. For example, the overlap width W ratio around the axial ends of the core material may be less than the overlap width W ratio in the central part of the core material. By making the overlap width W ratio different between the axial ends of the core material and the central part in this way, unraveling can be prevented. Furthermore, by maintaining a constant overlap width W in the central section, it becomes easier to control the tension applied to the label continuum, allowing the label continuum 2 to be wound stably.

[0019] In traverse winding, the maximum movement distance (maximum swing amplitude) of the winding position of the label continuum 2 in the axial direction relative to the core material 3 is, for example, 100 to 1000 mm, preferably 150 to 300 mm.

[0020] In manufacturing the label winding body 1, as shown in Figure 2, flange-shaped members 4 may be fixed to both axial ends of the core material 3 to limit the axial winding range of the label continuum 2. Alternatively, a winding method can be employed in which flange-shaped members are provided on the rotating shaft that holds the core material 3, so that no flange-shaped members remain on the core material 3 of the label winding body 1. Preferably, the outer diameter of the flange-shaped members 4 is greater than or equal to the outer diameter of the label winding body 1. By using a method in which flange-shaped members are placed at both ends of the core material before winding, it is possible to manufacture a label roll in a way that prevents the roll from unraveling.

[0021] [Label continuum] The label continuum 2 is a strip-shaped body that includes a strip-shaped separator 21 and a label 22 that is peelably attached to the separator 21. In the label continuum 2, for example, multiple labels 22 are attached at predetermined intervals to one side of a strip-shaped separator 21.

[0022] Typically, the width of the label 22 is smaller than the width of the separator 21, and the label 22 is peelably attached to the separator 21 with margins on both sides in the width direction of the separator 21.

[0023] The total width of the margins on both ends of the label 22 in the width direction on the separator 21 is preferably 1 mm to 10 mm, and more preferably 3 mm to 5 mm. While a margin width of 2 mm is preferable, increasing the margin width increases the manufacturing cost per label. The spacing between adjacent labels 22 in the longitudinal direction on the separator 21 is preferably 1 mm to 10 mm, and more preferably 3 mm to 5 mm. While it is preferable that the spacing between labels 22 be longer than the tolerance of the label feeding accuracy of the label application device (e.g., 3 mm), increasing the spacing between labels 22 increases the manufacturing cost per label.

[0024] In this embodiment, the width of the separator 21 may be, for example, 15 to 60 mm or 25 to 45 mm.

[0025] [Separator] In this embodiment, the strip-shaped separator 21 (release agent) is made of resin. By using a resin separator 21 that is softer (flexible) than paper separators, even if bending deformation occurs due to traverse winding, the deformation is less likely to remain after being unwound from the label winding body 1 due to its flexibility, thus reducing the likelihood of malfunctions when used in label application devices, etc. Furthermore, in the label winding 1, the separator 21 absorbs the bending deformation caused by traverse winding, so that even when the tension applied to the label continuum is weak, the winding of the label continuum does not loosen and collapse, and gaps do not form between the label continuums.

[0026] The separator 21 is, for example, a stretched film made of resin. The separator 21 is a stretched film made by extruding a single-layer or multi-layer resin sheet made of resin using a T-type die or the like, and then stretching it in a biaxial direction. Note that the stretched film has a higher elastic modulus in the stretching direction due to the stretching process (its elastic strength, as described later, becomes stronger and it becomes less stretchable when pulled). If the separator 21 is a biaxially oriented stretched film, the stretch ratios in the longitudinal (MD) and transverse (TD) directions are, for example, about 2 to 7 times. The stretched film may also be a uniaxially oriented film in the longitudinal direction.

[0027] (modulus of elasticity) In this embodiment, the elastic modulus (Young's modulus) of the resin film constituting the separator 21 is preferably 1000 N / mm². 2 More than 5000N / mm 2 The following, and more preferably 2000 N / mm 2 More than 4500N / mm 2 The following, and more preferably 3500 N / mm 2 More than 4500N / mm2 The following applies: In this case, a separator 21 having the elastic strength described later can be obtained within the range of the separator thickness described later. However, if the elastic modulus of the separator 21 is too low, a problem may occur in label application devices (especially dispensers where the tensile stress on the separator 21 is large) where the separator stretches.

[0028] (Elastic strength) In this embodiment, elastic strength is a value obtained by converting the elastic modulus to a value per 1 mm of separator width. The elastic strength of the separator 21 in the longitudinal direction (MD) is preferably 300 N / mm or less, and more preferably 100 N / mm or more and 250 N / mm or less. By using a soft separator 21 with a longitudinal elastic strength of 300 N / mm or less, deformation due to traverse winding can be more reliably prevented after the label is unwound from the label body 1, and the separator 21 can absorb the bending deformation caused by traverse winding in the label body 1. However, if the elastic strength in the vertical direction is too low, a problem may occur in label application devices (especially dispensers where the tensile stress on the separator 21 is large), where the separator may stretch.

[0029] (Tensile test) The elastic strength and modulus (Young's modulus) mentioned above are values ​​measured in tensile tests conducted using an autograph under the following conditions. Specifically, the tensile test method for measuring the modulus, and the methods for measuring and calculating the modulus, were carried out in accordance with the JIS K 7161 standard (JIS K 7161-1 Part 1: General rules, JIS K 7127 Part 3: Test conditions for films and sheets).

[0030] (Conditions for tensile testing) Measuring instrument: Autograph AG-X 500N (manufactured by Shimadzu Corporation) Tensile speed: 10 m / min Distance between gauge lines: 100mm Test specimen: Separator cut into strips 15 mm wide in both the MD and TD directions. Number of tests: n=6

[0031] The thickness of the separator is not particularly limited, but for example, it is 10 μm or more and 80 μm or less, preferably 10 μm or more and 60 μm or less, and more preferably 20 μm or more and 55 μm or less. The thickness of the base film can be measured using a micrometer.

[0032] Furthermore, the thickness of the label continuum 2 (the thickness of the thickest label portion) is not particularly limited, but is preferably 50 to 200 μm, and more preferably 70 to 150 μm. Note that the thickness of the label continuum 2 is the sum of the thickness of the base film and the thickness of the label (including the adhesive). When the thickness of the label continuum 2 is within this range, the label continuum 2 can be stably wound around the core material 3 using a traverse winding method.

[0033] (Polyester resin) In this embodiment, the separator is made of resin. The resin constituting the separator is preferably a polyester resin. The polyester resin is a resin containing polyester as the main component (a component accounting for 50% or more by mass). The proportion of polyester contained in the polyester resin is preferably 70% or more by mass, but may also be 80% or more by mass, 90% or more by mass, or 100% by mass.

[0034] Separators made of polyester resin are relatively softer (have a lower modulus of elasticity and lower elastic strength) than paper separators (release paper), making it easy to obtain separators with the above-mentioned elastic strength and modulus of elasticity.

[0035] Examples of polyesters (polyester resins) include polyethylene terephthalate (PET), polytrimethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, and polybutylene naphthalate. Among these, PET can be preferably used. One type of polyester may be used, or two or more types may be used.

[0036] Furthermore, the polyester resin may contain resins other than polyester.

[0037] However, the type of resin is not particularly limited as long as it is a resin capable of producing a separator (release film) having the above-mentioned elastic strength, modulus of elasticity, etc., and resins other than polyester resins may be used as the material for the separator. Examples of resins other than polyester resins include resins containing polyolefin as the main component (polyolefin resins). Examples of polyolefin resins include polypropylene, and among them, biaxially oriented polypropylene film is preferred. Furthermore, films obtained by mixing or laminating multiple types of resins, or films obtained by laminating other materials onto a resin film, may also be used, as long as the above-mentioned modulus of elasticity, etc., can be obtained.

[0038] Furthermore, the resin constituting the separator 21 may contain additives such as lubricants, fillers, heat stabilizers, antioxidants, ultraviolet absorbers, antistatic agents, antifogging agents, flame retardants, colorants, pinning agents (alkaline earth metals), and softeners, to the extent that they do not impair the effects of the present invention.

[0039] To facilitate the removal of the label 22 from the separator 21 (to improve release properties), a release agent may be applied to the surface of the separator 21. Examples of release agents include silicone-based release agents.

[0040] 〔label〕 The label 22 includes, for example, a base layer and an adhesive layer provided on the back surface of the base layer. Examples of the base layer include paper, synthetic paper, transparent film, milky white film, etc. The front surface (the side opposite the adhesive layer) of the label 22 (base layer) in this embodiment may be appropriately provided with a printed layer for displaying the design, a slippery overcoat layer, a matte coat layer with a non-glossy effect, and the like. The printed layer may include a design printed layer that displays text and images, and a background printed layer (for example, a solid white printed layer) laminated on the back side of the design printed layer to make the text and images appear clearer. However, if the base material layer is not a transparent film, the above solid white printed layer is not necessary.

[0041] Referring to Figure 3, the composition of the label 22 is not particularly limited. For example, the label 22 may consist of a single layer (see Figure 3(a)) or multiple layers (for example, two layers 22a and 22b) (see Figure 3(b)). Layers 22a and 22b are, for example, polyester layers. An adhesive layer (not shown) is provided on the separator 21 side of layers 22a and 22b.

[0042] The thickness of the label 22 including the adhesive layer is not particularly limited, but is preferably 30 to 150 μm, and more preferably 50 to 100 μm. Although the label 22 shown in Figures 1 and 2 is rectangular, the shape of the label is not particularly limited and may be a circle, ellipse, polygon, or any other shape.

[0043] As described above, an adhesive label material consisting of a label base, adhesive, and separator laminated together can be created, for example, by applying an adhesive to a separator coated with a release agent, drying it, and then laminating the label base layer. Furthermore, such an adhesive label material (adhesive label material, tack base paper) can be selected and used from materials having a resin release film (separator) sold by companies such as Lintec Corporation and Avery Dennison.

[0044] <Feeding device> The present invention also relates to a dispensing device 5 for dispensing a continuous sheet of labels from the label roll 1 described above. In order to use the continuous label material of the label roll 1 described above with a conventional label application device (tack labeler), a method is required to feed it stably without causing meandering or other issues. Therefore, the present invention also relates to a feeding device 5 for feeding out the continuous label material in order to implement an effective method of using the label roll 1 described above.

[0045] Referring to Figures 5 and 6, the dispensing device 5 includes a rotating shaft 51 that rotatably holds the label roll 1 from the inside of the core material, and an inverted crown-shaped roller 52 or conical guide 53 for feeding (receiving) the dispensed label continuum 2 to the next process (for example, the label application process). The inverted crown-type roller 52 is a cylindrical roller with a shape in which the diameter gradually decreases from both ends in the axial direction towards the center, and is rotatably mounted by contacting the outer surface of the label continuum that is sent to the next process. The conical guide 53 is a conical cylinder with an opening at the apex of the cone that is large enough for the label continuum 2 to pass through.

[0046] The inverted crown roller 52 or the conical guide 53 can be installed in a stable position where they do not move, for example. If they are installed, for example, near the center of the label winding 1 in the axial direction, even if the dispensing position of the label continuum 2 from the label winding 1 reciprocates in the axial direction and the angle at which the label continuum 2 is fed to the inverted crown roller 52 or the conical guide 53 changes, the outer surface of the inverted crown roller 52 or the inner surface of the opening of the conical guide 53 can follow the label continuum 2, thus allowing the label continuum 2 to be fed stably.

[0047] Here, the rotating shaft 51 may be capable of reciprocating movement in the axial direction. In this case, for example, by reciprocating the rotation shaft 51 using a rocking mechanism 51a or the like so that the position where the label continuum 2 is fed out from the label winding body 1 in the axial direction is close to the inverted crown-shaped roller 52 or the conical guide 53 (see Figure 5(b)), the angle at which the label continuum 2 is fed to the inverted crown-shaped roller 52 or the conical guide 53 becomes constant, and the label continuum 2 can be fed more stably.

[0048] A oscillating roller 54 may be further provided between the inverted crown-shaped roller 52 or conical guide 53 and the label winding body 1, which is reciprocally movable in the axial direction and redirects the label continuum 2 unwound from the label winding body 1 toward the inverted crown-shaped roller 52 or conical guide 53 (see Figure 5(a)). For example, as shown in Figure 5(a), the oscillating roller 54 is configured to reciprocate in the axial direction by being rotatably supported by a base 54a and having a base 54a that is slidable relative to a shaft 54b. As the oscillating roller 54 moves back and forth in the axial direction, the change in the angle at which the label continuum 2 is fed to the inverted crown-shaped roller 52 or the conical guide 53 is reduced, allowing the label continuum 2 to be fed more stably. In this case, it is preferable that the axis of the oscillating roller 54 be tiltable according to the direction in which the label continuum 2 is taken up by a spring mechanism or the like. In this case, the angle at which the label continuum 2 is fed to the oscillating roller 54 is constant, so the label continuum 2 can be fed more stably. Thus, by using the feeding device of the present invention to feed the label continuum 2 of the label winding 1, the label continuum 2 can be stably fed to the next process, such as a labeler, even from both ends in the axial direction. [Examples]

[0049] (Examples 1-5, Comparative Examples 1-2) The label rolls for Examples 1-5 and Comparative Examples 1-2 were prepared as follows.

[0050] First, a label continuum (label with separator) 2 was prepared, in which a label 22 was attached to one side of a separator 21 as shown in Figure 3(a). The following products were used as the label continuum for Examples 1-5 and Comparative Examples 1-2. Example 1: Lintec adhesive label material (tack label base paper: label substrate / adhesive / separator) "PET50 K2411 / PA-T1 / PET25" Example 2: Lintec adhesive label material "Synthetic Paper 80 / PA-T1 / PET38" Example 3: Lintec adhesive label material "PET50 / PA-T1 / PET50" Example 4: Lintec adhesive label material "Unoriented PET50 / UV adhesive / Unoriented PET60" Example 5: Lintec adhesive label material "PET25 / PA-T1 / OPP50" Comparative Example 1: Lintec's adhesive label material "Synthetic Paper 80 / CHILL AT / Paper Release Paper" Comparative Example 2: Lintec's adhesive label material "Synthetic Paper 80 / PA-T1 / Paper Release Paper" Note that "Synthetic Paper 80" above refers to void-containing synthetic paper (thickness: 80 μm). The adhesive thickness is approximately 10-20 μm.

[0051] The materials used for the separators in each of Examples 1-5 and Comparative Examples 1-2 are shown in Table 1. Table 1 shows the measured thickness of the separator. The separator thickness was measured using a micrometer. The width of the separator was 43 mm. A release agent was applied to one side of all separators in Examples 1-5 and Comparative Examples 1-3.

[0052] In all label continuum 2 of Examples 1-3 and Comparative Examples 1-3, the lengthwise spacing between labels is 3 mm, and the width of the margin in the widthwise direction is 1.5 mm on each side.

[0053] Next, using a winding device, the label winding bodies for Examples 1-3 and Comparative Examples 1-3 were produced by winding the prepared label continuum onto the core material in a traverse winding manner. In the traverse winding, the ratio of the displacement width Z mentioned above was set to be the same (approximately 20 mm) throughout the entire axial direction of the core material.

[0054] <Tensile Test> The elastic modulus and elastic strength were measured for the separators used in each of the label rolls in Examples 1-5 and Comparative Examples 1-3 described above. Note that the elastic strength here is the value obtained by converting the elastic modulus to a value per 1 mm of separator width. The modulus of elasticity (Young's modulus) and elastic strength were measured in tensile tests conducted using an autograph under the following conditions. Specifically, the tensile test method for measuring the modulus of elasticity, and the methods for measuring and calculating the modulus of elasticity were carried out in accordance with the JIS K 7161 standard (JIS K 7161-1 Part 1: General rules, JIS K 7127 Part 3: Test conditions for films and sheets).

[0055] (Conditions for tensile testing) Measuring instrument: Autograph AG-X 500N (manufactured by Shimadzu Corporation) Tensile speed: 10 m / min Distance between gauge lines: 100mm Test specimen: Separator cut into strips 15 mm wide in both the MD and TD directions. Number of tests: n=6

[0056] Table 1 shows the measured elastic modulus and elastic strength for each separator. For reference, Table 1 also includes the measured values ​​for elastic modulus and elastic strength in the transverse direction (TD), in addition to the longitudinal direction (MD).

[0057] [Table 1]

[0058] (result) In the label rolls of Examples 1 to 5 using a resin separator, loosening of the winding of the label continuum and unwinding, or the generation of gaps between the label continua were suppressed. In contrast, in the label rolls of Comparative Examples 1 and 2 using a paper separator, phenomena such as loosening of the winding of the label continuum and unwinding, or the generation of gaps between the label continua were confirmed.

[0059] From the measured values shown in Table 1, by using a soft separator with a longitudinal modulus of elasticity of 1000 N / mm 2 or more and 5000 N / mm 2 or less, even when the tension applied to the label continuum is weak, loosening of the winding of the label continuum and unwinding, or the generation of gaps between the label continua are suppressed, and it is considered that deformation due to traverse winding is unlikely to remain after being fed out from the label roll 1. Also, it is considered preferable that the elastic strength is 300 N / mm or less.

[0060] Note that in Example 5 where the longitudinal modulus of elasticity is 2000 N / mm 2 or less, when pasting is performed with a label pasting device, there is a possibility that the separator will stretch.

[0061] The present invention is not limited to the above embodiments and can be variously modified. Two or more embodiments selected from the above various embodiments may be appropriately combined, or at least one configuration (part of the configuration) selected from the above various embodiments may be replaced with a part of the configuration of other embodiments.
