Abstract

PROBLEM TO BE SOLVED: To provide a method to accurately determine the number of seams in a label continuous body in the state of being wound in a roll shape.SOLUTION: This invention provides a method to accurately determine the number of seams in a label continuous body 1 in the state of a roll 100 being wound in a roll shape, formed from at least two long label base materials tied with one or more connection members. X rays are radiated to the label continuous body 1 in the roll shape so as to determine the number of seams A on the basis of a difference in X-ray transmission amounts between the connection member and the long label base material.

Description

  The present invention relates to a method for detecting the number of seams included in a label continuum in which a plurality of labels are continuously connected.

Conventionally, various labels are attached to various adherends such as containers for storing beverages, products themselves, packaging boxes for wrapping products, etc., and are provided to consumers as packages (adhered substrates with labels). ing.
Generally, a label manufacturer and a label user are different from each other, and a user purchases a label manufactured by the label manufacturer and attaches the label to an adherend.
As labels, there are broadly known cylindrical labels that are attached to the adherend by heat shrinkage, wound labels that are wound around the adherend, and the like. These labels may be provided to the user in the form of a single sheet, but usually in order to continuously attach the label to the adherend using a labeler (label mounting device), A plurality of labels are provided in the form of a label continuous body continuously connected in the longitudinal direction. Since such a label continuous body is elongate, it is usually provided to the user in a roll wound up in a roll.

By the way, the length of the label continuum is often determined in advance according to a user's request, a labeler, a label type, and the like. For example, some users seek a label continuum with a length of 1000 m, others ask for a label continuum with a length of 1200 m, and for some labels, a label continuum with a length of 1500 m It seems that it is required. The manufacturer repeatedly prints a desired design in the longitudinal direction of the long original fabric substrate, and if necessary, creates a long label substrate by forming it into a cylindrical shape, etc. By cutting to a specified length (hereinafter referred to as a specified length), a label continuous body having a specified length is obtained and provided to the user as a scroll.
However, the length of the long original fabric substrate and the specified length of the label continuous body to be obtained are usually not the same, and the longer original fabric substrate is often longer. For this reason, for example, when a 3000 m original fabric base material is used when producing a label continuous body having a specified length of 1200 m, a 600 m long label base material is an end material (a length less than the specified length). It will remain as a scale label substrate. Further, when printing or the like is performed on the raw fabric base material, an end material may be generated due to an unexpected trouble such as a printing mistake or a twisted base material. Since the end material is a continuous continuous label except that the end material is less than the specified length, the end material is usually not discarded, but is connected in the longitudinal direction to the specified length label. A continuum is produced.
For example, as in Patent Document 1, a continuous label body having a specified length is produced by joining long label substrates that are less than a specified length with an adhesive tape.

When the connected continuous label body of the specified length is attached to an adherend with a labeler to produce a package, a package (hereinafter referred to as defective packaging) in which a label with an adhesive tape is attached in the production lot. The body). The defective package is mechanically detected and eliminated in the production line of the package, and only normal packages are packed and shipped.
On the other hand, when a label manufacturer provides a continuous label continuum, the number of seams in the label continuum is transmitted to the user.
The user checks the number of seams notified by the manufacturer and the number of defective packages eliminated in the line, and manages so that the defective packages are not mixed in the normal package. doing.

  However, the long label base material that does not meet the specified length is manually joined by the operator, and the number of seams is counted by the operator in parallel with the joining work. There is a risk of erroneously counting the number of seams different from the number of seams. If the number of joints is mistakenly communicated to the user, the number of seams obtained from the manufacturer will not match the number excluded as defective packaging, so the user will need to inspect the packaging. is there. In particular, if the number of reported seams is greater than the number of defective packages actually eliminated, the user suspects that the defective packages are mixed in the normal package. The package of the lot must be opened and all packages must be inspected artificially.

[Overview of label continuum]
The label continuum of the present invention is conceptually formed by continuously connecting a plurality of labels. Therefore, the design of one label is applied in the same direction and at equal intervals in the longitudinal direction of the long substrate.
The label continuum is formed by arranging two or more long label substrates in the longitudinal direction and connecting the long label substrates with a connecting member. The joined label continuum has an elongated shape with a specified length. The specified length is not particularly limited and can be set variously.
In addition, the said elongate label base material and a label continuous body are the structures substantially the same except the length of a longitudinal direction differing. That is, the label continuum of the present invention is a label continuum having a predetermined length in which a plurality of labels are continuously connected, and the long label substrate satisfies a specified length in which a plurality of labels are continuously connected. There is no label continuum.

[Continuous Label of First Embodiment]
The label continuum of the first embodiment is one in which a plurality of cylindrical labels are continuously connected.
FIG. 1 is a plan view of a continuous cylindrical label (partially omitted), and FIGS. 2 and 3 are cut surfaces (cut surfaces) when cut in the longitudinal direction and the short direction. FIG.
In FIG. 1 thru | or FIG. 3, the label continuous body 1 of this embodiment is a cylindrical label continuous body with which the several cylindrical label was connected continuously. Accordingly, the design of one cylindrical label is applied in the same direction in the longitudinal direction and at equal intervals. When the cylindrical label continuous body 11 is attached to the adherend, the cylindrical label continuous body 11 is cut at a position indicated by a one-dot chain line in FIG. 1 to obtain individual cylindrical labels. Hereinafter, also in the label continuous body of FIG.5, FIG.7, FIG.12 and FIG. 14, the location (scheduled cutting line) cut | disconnected at the time of mounting | wearing to a to-be-adhered body is shown with the dashed-dotted line.

The cylindrical label continuous body 11 is formed by connecting two or more cylindrical long label substrates 2 and 2 with a connecting member 3. The connecting member 3 is provided at a position so as not to overlap the planned cutting line indicated by the alternate long and short dash line.
FIG. 1 illustrates a state in which the joint A of the two long label base materials 2 and 2 is connected by the connecting member 3. In addition, in one cylindrical label continuous body 11, the joint A is not limited to one place as shown in FIG. 1, and there may be two or more places. When there are two or more joints A, two or more connecting members 3 are provided correspondingly.
The cylindrical label continuous body 11 is flattened by being folded at first and second folds 1a and 1b extending in the longitudinal direction and facing each other.

The long label base materials 2 and 2 constituting the cylindrical label continuous body 11 of the present invention are obtained by rolling a long original fabric base material 21 provided with a design printing layer 22 on at least one surface into a cylindrical shape. It is formed by adhering both end portions 21a and 21b. As described above, the long label base materials 2 and 2 are end materials that are produced when a continuous label body having a specified length is manufactured.
At the seam A, the edges of the two long label substrates 2 and 2 are abutted. Two adjacent long label base materials 2 and 2 are aligned at the joint A so that the design represented by the design print layer 22 is continuous.
In addition, in the joint A, the two long label base materials 2 and 2 are not limited to the case where the end edges are butted, and the end portions of the two long label base materials 2 and 2 may be somewhat separated from each other. Alternatively, the two ends may be overlapped on the front and back. Moreover, when the two long label base materials 2 and 2 are cylindrical like this embodiment, the edge part of one long label base material 2 is connected to another long label base material 2. Two ends may be overlapped by being inserted into the ends.

The cylindrical label continuous body 11 (cylindrical label) may have heat-shrinkability and / or self-stretchability or may not have these properties. The heat shrinkability refers to the property of heat shrinking at least in the main stretching direction (circumferential direction in the cylindrical label) when heated to a required temperature, and the self-stretchability is increased by applying an expansion force. It means the property of restoring to its original size by extending in the direction and releasing the expansion force.
A cylindrical label continuum (cylindrical label) having heat-shrinkability can be prepared using a raw fabric base material made of synthetic resin having heat-shrinkability, and has a self-stretching cylindrical label continuum (cylindrical label). ) Can be produced using a self-stretchable synthetic resin base material, and a continuous cylindrical label (heat-shrinkable and self-stretchable) is a heat-shrinkable and self-stretchable material. It can produce using the raw material base material made from the synthetic resin which has. A heat-shrinkable cylindrical label continuous body (cylindrical label) is also called a heat-shrinkable cylindrical label, a shrink label, a shrink film, and the like. For example, various decorations for beverage containers, cap seals for various containers, etc. It is used for various purposes. A cylindrical label continuous body (cylindrical label) having self-stretchability is also referred to as a stretch label, a self-stretchable cylindrical label, and the like, and is used for various applications such as decoration of containers containing carbonated beverages. Cylindrical label continuous bodies (cylindrical labels) having heat shrinkability and self-stretchability are also referred to as stretch shrink labels and the like, and are used in various applications as well.
The uses, materials, configurations, and the like of these cylindrical labels are disclosed in many documents such as JP2011-207502, JP2013-050711, and so on.

The connecting member 3 is not particularly limited as long as the adjacent long label substrates 2 and 2 can be connected.
In the illustrated example, an adhesive tape is used as the connecting member 3. This sticking tape has a sheet 31 and a sticking layer 32 provided on the back surface of the sheet 31. The connecting member 3 is pasted so as to cover the joint A.
For example, as shown in FIGS. 1 to 3, the strip-shaped connecting member 3 covers the seam A, which is a portion where the ends of two adjacent long label substrates 2 and 2 are attached, and has a cylindrical length. It is wound around the entire circumferential direction of the scale label substrate 2, and its one end 3a is laminated and pasted on the other end 3b. Thus, by providing the connection member 3 around the elongate label base material 2, it becomes easier to detect the position of the connection member 3 when X-rays are irradiated.

But the connection structure of the elongate label base materials 2 and 2 by the connection member 3 is not restricted above, It can change variously.
For example, as shown in FIG. 4, the connecting member 3 is wound in the circumferential direction of the long label substrate 2, and the other end of the connecting member 3 is disposed between both side ends 21 a and 21 b of the long label substrate 2. It may be pasted so that part 3b may be inserted. In such a connecting structure, in the manufacturing process of the label continuous body, before the long base material is formed into a cylindrical shape, the two long base materials are connected by a connecting member, and the long base material connected is connected to the cylinder. It is a structure obtained when it is rounded into a shape and both end portions thereof are bonded.
Further, for example, as shown in FIGS. 5 and 6, the connecting members 3 are long so that the end edges of the two long label substrates 2 and 2 are abutted and the seam A generated between the end edges is covered. You may affix on the at least one surface (preferably one side and the other side respectively) of the edge part of the scale label base materials 2 and 2.
Further, for example, as shown in FIGS. 7 to 9, after the end portion 2 c of one long label substrate 2 is inserted and joined to the inside of the end portion 2 d of the other long label substrate 2. The connecting member 3 may be attached to one surface of the end portions of the long label substrates 2 and 2 so as to cover the joint A between the two long labels 2 and 2. Preferably, as shown in FIG. 8, the connecting member 3 is affixed to one side and the other side of the long label substrates 2 and 2, respectively. Thus, by providing the two connecting members 3 so as to sandwich the long label base material 2 between them, the connecting members 2 are connected when irradiated with X-rays as in the case where the connecting members 2 are provided in the surroundings. It becomes easier to detect the position of the member 3.

  The connecting member 3 has a portion whose X-ray transmission amount is different from the X-ray transmission amount of the long label substrate 2. That is, the X-ray transmission amount in a part or all of the connection member 3 when the connection member 3 is irradiated with X-rays and the X-ray transmission amount when the long label substrate 2 is irradiated with X-rays are different. The connecting member 3 is used. In addition, the long label base material 2 has the raw fabric base material 21 and the design printing layer 22, and has any other layers as necessary. However, a part or all of the connecting member 3 has its X It is preferable that the amount of transmitted light is different from the amount of transmitted X-rays of all the components constituting the long label substrate 2. In order to more clearly distinguish the connecting member 3 from the long label base material 2 due to the difference between the X-rays that pass through the long label base material 2 and the X-rays that pass through the connecting member 3 when irradiated with X-rays. is there.

Here, the X-ray transmission amount decreases as the specific gravity of the object increases, and decreases as the thickness of the object increases. In other words, the amount of X-ray transmission is inversely proportional to the specific gravity of the object and inversely proportional to the thickness of the object. Furthermore, if the object contains metal, the amount of X-ray transmission may be low. In order to make the X-ray transmission amount with respect to the long label base material 2 different, the connecting member is such that the specific gravity or thickness of a part or all of it is different from the specific gravity and / or thickness of the long label base material 2. Used. Preferably, the connection member 3 containing a metal is used.
For example, when the thickness of the long label base material 2 is the same as part or all of the connection member 3, the connection member has a specific gravity that is larger or smaller than the specific gravity of the long label base material 2. 3 is used, and when the specific gravity of part or all of the connecting member 3 and the long label substrate 2 is the same, the thickness of part or all of the connecting member 3 is greater than the thickness of the long label substrate 2 or A small connecting member 3 is used. Preferably, when both thicknesses are the same, a connecting member 3 having a specific gravity of a part or all of which is larger than the specific gravity of the long label base material 2 is used, and when the specific gravity of both is the same. The connecting member 3 having a part or all of the thickness larger than the thickness of the long label substrate 2 is used.
In general, considering that the specific gravity of the long label substrate 2 is sufficiently small including the design printing layer, the difference in X-ray transmission amount becomes larger. It is preferable to use a connecting member 3 larger than the specific gravity of 2, and it is more preferable to use a connecting member 3 whose partial or total specific gravity and thickness are larger than the specific gravity and thickness of the long label substrate 2.
In addition, for example, when the specific gravity of the connecting member 3 is considerably larger than the specific gravity of the long label base material 2, it is also possible to use the connecting member 3 having a thickness smaller than the thickness of the long label base material 2, Further, when the thickness of the connecting member 3 is considerably larger than the thickness of the long label base material 2, it is possible to use the connecting member 3 having a specific gravity smaller than the specific gravity of the long label base material 2. In short, the connecting member 3 having a portion where the X-ray transmission amount is different from the X-ray transmission amount of the long label substrate 2 may be used.

In general, cylindrical label to be attached to various adherends is a thickness 10 m - 100 ^m, many of them having a specific gravity of ^{0.80g / cm 3 ~1.5g / cm 3} .
Long label substrate constituting such cylindrical label is also a thickness 10 m - 100 m, a specific gravity of ^{0.80g / cm 3 ~1.5g / cm 3} .
The connecting member 3 that connects the long label substrate 2 preferably contains a material that reduces the amount of X-ray transmission, more preferably contains a metal, and more preferably contains a metal having a specific gravity of 3 g / cm ³ or more. The connecting member 3 preferably has a layer with a small amount of X-ray transmission, more preferably a layer containing a metal, still more preferably a layer containing a metal and a specific gravity of 3 g / cm ³ or more. Particularly preferred is a layer containing a metal and having a specific gravity of 5 g / cm ³ or more.
In addition, although the long label base material 2 may also contain a metal, the amount is very small and it is not contained so finely that the X-ray transmission amount is lowered. The thickness of the layer containing is also extremely small. For example, the ink component of the design printing layer 22 may contain a metal or an oxide thereof, and the thickness of the metal-containing printing layer is about several μm. That is, the connecting member 5 has a part or all of its thickness larger than the thickness of the metal-containing printing layer of the long label substrate 2.

  Even when the long label substrate 2 contains metal, the connecting member 3 has a layer having a smaller amount of X-ray transmission than all the components constituting the long label substrate 2. ing. Since the connecting member 3 and the long label base material 2 can be clearly distinguished by X-rays, when the connecting member 3 contains a metal, the long label base material 2 substantially contains the metal contained in the connecting member 3. It is preferably not included. In addition, the long label base material 2 does not substantially contain the metal of the connecting member 3, and the metal of the connecting member 3 is not included in all the constituent elements constituting the long label base material 2. In addition to the case where the metal is not present, the meaning includes the case where the metal inevitably remains such as a catalyst residue or the case where the metal is included due to unintentional mixing.

Specifically, in this embodiment, at least the sheet 31 of the connecting member 3 is different in X-ray transmission amount from the long label substrate 2, and preferably X-rays are more than the X-ray transmission amount of the long label substrate 2. The amount of transmission is small.
Specifically, the sheet 31 is, for example, a sheet having a required shape in plan view (for example, a rectangular shape in plan view) having flexibility.
The material for forming the sheet 31 is not particularly limited as long as it has a layer showing an X-ray transmission amount different from that of the long label substrate 2. The material for forming the sheet 31 is, for example, a single-layer metal foil or a multi-layer metal foil made of one or more metals, a metal laminated film in which the metal foil is laminated on a film other than metal, and a film other than metal. Examples thereof include a metal vapor-deposited film obtained by laminating a metal vapor-deposited film and a film obtained by coating a metal-containing printing layer on a film other than metal. It is preferable that the sheet | seat 31 of the connection member 3 has a metal layer like the said metal foil, a metal vapor deposition film, and a metal containing printing layer.
The thickness of the metal foil is not particularly limited, but if it is too small, it may be difficult to clearly distinguish it from the image of the long label substrate 2 when irradiated with X-rays. 5 μm or more is more preferable, and 8 μm or more is more preferable. On the other hand, if the thickness of the metal foil is too large, the metal foil lacks flexibility, and it becomes difficult to wind the label continuous body 1 into a roll, and the labeling suitability using a labeler is deteriorated. Or less, more preferably 50 μm or less, and particularly preferably 30 μm or less. The thicknesses of the metal vapor deposition film and the metal-containing layer are not particularly limited. However, if the thickness is too small, it may be difficult to clearly distinguish the image of the long label substrate 2 when irradiated with X-rays. 0.3 μm or more is preferable, 0.5 μm or more is more preferable, and 1 μm or more is more preferable. On the other hand, since it is difficult to produce a metal deposition film that is too thick, the thickness of the metal deposition film and the metal-containing layer is preferably 3 μm or less.
Examples of the film other than the metal include paper; a synthetic resin film such as a polyester film such as polyethylene terephthalate; and the like. The thickness of the film other than the metal is, for example, 10 μm to 100 μm.

The metal is not particularly limited, and various metals can be used. In particular, the metal contained in the connecting member 3 is preferably a metal other than aluminum and titanium, more preferably a metal other than aluminum and titanium, a metal having a specific gravity of 3 g / cm ³ or more, and a specific gravity of 5 g / cm ^3. The above metals are more preferable, and at least one selected from nickel and copper group elements is particularly preferable. Examples of the copper group element include copper, silver, and gold, but copper is preferable in consideration of cost.
When a metal layer is used as the connecting member 3, the metal of the connecting member 3 is used to prevent corrosion or the like of the surface of the label continuous body 1 in contact with the connecting member 3 when the label continuous body 1 is rolled up. The surface of the layer is preferably covered with a synthetic resin film.

The long label substrate 2 may be provided with a gas barrier layer made of an aluminum vapor deposition film, a silver ink printing layer containing aluminum, or a white ink printing layer containing titanium oxide. Since the thickness of these metal-containing printing layers is several μm as described above, they are not included so densely as to reduce the X-ray transmission amount of the long label substrate. However, when the same metal (aluminum and / or titanium) as the metal-containing printed layer of the long label substrate 2 is used as the metal of the connecting member 3, the difference in the amount of X-ray transmission is caused to make the connecting member 3 a long label. In order to distinguish from the base material 2, it is necessary to make the thickness of the connection member 3 into 20 times-100 times of the metal containing printing layer of the elongate label base material 2, for example. When the connecting member 3 becomes thick in this manner, it is difficult to wind the label continuous body 1 in a roll shape, and there is a possibility that the suitability for attaching a label using a labeler may deteriorate. In this regard, by using the connecting member 3 containing a metal other than aluminum and titanium, when the X-ray is irradiated without greatly increasing the thickness of the connecting member 3, the connecting member 3 and the long label base material 2 are The connecting member 3 can be clearly distinguished from the long label base material 2 without being confused.
Further, according to the study by the present inventors, the larger the specific gravity, the lower the amount of X-ray transmission. Therefore, the long label base material 2 preferably has a specific gravity of less than 3 g / cm ³ , The specific gravity is preferably 2.5 g / cm ³ or less, and particularly preferably less than 2 g / cm ³ . The lower limit of the specific gravity of the constituent elements of the long label substrate 2 theoretically exceeds zero, but is generally 0.8 g / cm ³ or more.
In this specification, specific gravity is specific gravity with respect to the density of 20 degreeC water.

The patch layer 32 is made of a conventionally known patch. The patch is not particularly limited as long as it can be firmly bonded to the long label substrate 2, and examples thereof include a known pressure-sensitive adhesive or adhesive.
In the present embodiment, a pressure-sensitive adhesive is used as the patch, and the adhesive layer 32 is formed by laminating the adhesive on the back surface of the sheet 31 in a solid shape.
In the above description, the sheet 31 of the connecting member 3 is configured so that the X-ray transmission amount is different from that of the long label substrate 2, but instead of or in combination with this, the adhesive layer 32 is long. You may comprise so that X-ray transmission amount may differ from the scale label base material 2. FIG. For example, the adhesive layer 32 may be formed by mixing the above-described metal that reduces the amount of X-ray transmission into the patch.

For example, when using copper foil, the connection member 3 is comprised by PET film (10 micrometers-50 micrometers) / copper foil (5 micrometers-30 micrometers) / sticking agent (15 micrometers-25 micrometers). Since the difference in the amount of X-ray transmission increases, the label continuous body 1 becomes easy to handle when wound in a roll shape, and the label is suitable for mounting using a labeler. The thickness is preferably 10 μm to 100 μm, more preferably 20 μm to 80 μm, and even more preferably 40 μm to 60 μm.
As shown in FIGS. 10 and 11, the cylindrical label continuous body 11 of the present invention detects the number of seams described later in the state of a roll 100 wound around the core material 4 in a roll shape, and stores / Provided for transportation.

[Continuous Label of Second Embodiment]
The label continuum of the second embodiment is a wound label continuum in which a plurality of labels are continuously connected.
FIG. 12 is a plan view of the wrapping label continuum (partially omitted), and FIG. 13 is a view of a cut surface (cut surface) when cut in the longitudinal direction and the short direction. .
12 and 13, the label continuous body 1 according to the present embodiment is a winding in which two or more strip-shaped long label base materials 2 and 2 are arranged in the longitudinal direction and joined together at a joint A by a connecting member 3. This is a label continuum 12.
In the long label substrate 2 of the present embodiment, a heat-sensitive adhesive layer 23 is provided on a long strip-shaped raw fabric substrate 21 provided with a design printing layer 22 on at least the back surface. The heat-sensitive adhesive layer 23 is formed by applying a heat-sensitive adhesive to the raw fabric substrate 21. The heat-sensitive adhesive layer 23 is provided, for example, only in a region having a required width including the planned cutting line of the label continuous body 1. But the heat sensitive adhesive layer 23 may be provided in the whole back surface of the label continuous body 1. FIG. A heat-sensitive adhesive is an adhesive that exhibits adhesiveness at room temperature and exhibits adhesiveness when heated. Other configurations are the same as those in the first embodiment.
This winding label continuous body 12 (winding label) is affixed to a to-be-adhered body with a heat sensitive adhesive. The use, material, and configuration of the winding label are disclosed in Japanese Patent Application Laid-Open No. 2006-106234, Japanese Patent Application Laid-Open No. 2006-330552, and the like.
Also in the label continuous body 1 of the present embodiment, the number of seams A is detected in the state of the roll 100 wound up in a roll shape.
In addition, the continuous label body of the present invention may be one in which a plurality of glue labels are continuously connected, one in which a plurality of tack labels are continuously connected, and the like (none of them are shown). The glue label is a label to which a pressure-sensitive adhesive or an adhesive is applied at the time of use. Therefore, the heat-sensitive adhesive or the like is not provided on the back surface of the label continuous body of the glue label. The tack label is a label provided with a pressure-sensitive adhesive in advance. Therefore, the label continuum of the tack label is a long strip that temporarily attaches the tack label provided with the pressure-sensitive adhesive. Has a pattern.

[Seam detection method for continuous label]
The seam detection method of the present invention irradiates X-rays from an arbitrary direction of the scroll in a state in which the label continuum is wound up in a roll shape, and the amount of X-ray transmission between the connecting member and the long label base material. The number of seams is detected based on the difference.
Specifically, as shown in FIG. 16, an X-ray irradiation device 91 is arranged on one side of the roll 100 of the label continuous body 1. On the other hand, an X-ray detector 92 is disposed on the other side surface of the scroll 100 of the label continuous body 1. An imaging device (not shown) is connected to the X-ray detector 92. The scroll 100 is irradiated with X-rays from the X-ray irradiation device 91 (thick arrow in FIG. 16). The irradiated X-ray hits the roll 100 of the label continuum 1, while some X-rays are absorbed or reflected, the X-ray passes through the roll 100 of the label continuum 1, and the transmitted X-ray is detected by X-rays Detected by the instrument 92. The transmitted X-ray is indicated by a white arrow. The X-ray transmission amount data detected by the X-ray detector 92 is sent to the imaging device, and the imaging device creates an image according to the magnitude of the X-ray transmission amount. Examples of the imaging device include a computer X-ray machine such as a digital camera with a printing function or an image display device. The photographing method may be a method in which the scroll 100 is photographed in a line shape with a line camera and the whole image is created by synthesizing those images, or the whole image is photographed at once with an area camera. It may be a method of creating.
Usually, the imaging apparatus displays a portion having a large amount of X-ray transmission as a thin image and a portion having a small amount of X-ray transmission as a dark image. However, a portion having a large amount of X-ray transmission may be displayed as a dark image, and a portion having a small amount of X-ray transmission may be displayed as a thin image.

And the X-ray is irradiated to the whole scroll 100 of the label continuous body 1, and the transmitted X-ray is detected. When the X-ray irradiation device 91 and the X-ray detector 92 are capable of irradiating and detecting the X-ray at a time on the roll 100 of the label continuum 1, an image can be created in a short time.
When the X-ray irradiation part of the X-ray irradiation apparatus 91 and the detection part of the X-ray detector 92 are smaller than the scroll 100 of the label continuum 1, a plurality of X-ray irradiation apparatuses and X-ray detectors are used. A set may be used, or a set of X-ray irradiation apparatus and X-ray detector may be used. When using the set, (1) the scroll 100 is fixed, and the X-ray irradiation device 91 and the X-ray detector 92 are moved relative to the scroll 100, and (2) the X-ray irradiation device 91 and the X-ray. The detector 92 is fixed and the scroll 100 is moved with respect to the X-ray irradiation device 91, or (3) the X-ray irradiation device 91, the X-ray detector 92 and the scroll 100 are moved relative to each other. The entire roll 100 of the continuum 1 can be irradiated with X-rays to detect the transmitted X-rays. However, even when a plurality of sets are used, the X-ray irradiation apparatus and / or the X-ray detector may be moved.
Specific detection conditions for detecting the seam of the scroll 100 of the label continuous body 1 include, for example, an irradiation distance from the X-ray irradiation device 91 to the X-ray detector 92 of 500 mm to 1500 mm, from the X-ray detector 92. The distance to the label continuous body 1 is set to 10 mm to 50 mm, the tube voltage of the X-ray irradiation apparatus 91 is set to 50 kV to 150 kV, and the tube current is set to 2 mA to 10 mA.

As described above, since a part or all of the connecting member 3 has a different X-ray transmission amount from the long label base material 2, the location where the connecting member 3 exists is long as shown in FIG. 17. It is displayed as an image different from the label substrates 2 and 2. In the drawing, since the density of the image cannot be represented, the connecting member 3 is represented by a thick line.
For example, when part or all of the connecting member 3 has a smaller amount of X-ray transmission than the long label base materials 2 and 2, the connecting member 3 is included in the image of the long label base materials 2 and 2 that appear thinly. A dark image showing the location of the appears. By this image difference, it is possible to easily read how many connecting members 3 are present in the roll 100 of one label continuous body 1. In the illustrated example, since three dark images appear in the thin wound pattern image (long label base materials 2 and 2), it can be seen that the connecting members 3 exist at three locations. It can be seen that the continuous label body 1 has four long label substrates 2 and 2 connected by three seams A.
The number of the seams A based on the created image may be measured by human eyes or may be mechanically analyzed by analyzing the density of the image with a computer. From the viewpoint of minimizing human error, the operation of the X-ray irradiation device 91 and the X-ray detector 92 and the measurement of the number of joints A (connection member 3) based on the magnitude of the X-ray transmission amount are performed by a computer. It is preferable to carry out automatically. In addition, when automatically performing with a computer, the image for recognizing by human vision is not necessarily required, and thus the imaging device can be omitted.

According to the present invention, the number of seams A of the continuous label continuous body 1 can be reliably grasped. Conventionally, when an operator joins long label substrates that do not meet the specified length, the number of seams is recorded, but the seaming work and the number of seams must be recorded. There was a risk of miscounting the number of seams.
In this respect, according to the method of the present invention, since the number of seams A of the completed label continuous body 1 is measured using X-rays, an artificial mistake can be prevented. Further, when the label continuous body 1 is a scroll 100, the connecting member 3 (the seam A) is buried in the scroll 100 and the number cannot be measured, but if X-rays are used, Since the connecting member 3 can be detected in a state in which the label continuous body 1 is wound in a roll shape, the measurement operation of the joint A can be easily performed.
Further, according to the present invention, after the operator records the joining operation and the number of joints A, another inspector uses the X-ray to determine the number of joints A of the label continuum 1. It can also be measured. That is, the inspector can further increase the accuracy of the number of seams A by collating the number of counts and the number of measurements of the worker. In addition, the user who is provided with the scroll can separately measure the number of seams A of the provided scroll using X-rays.

In the above embodiment, the X-ray detector 92 and the imaging device are used as means for irradiating X-rays and creating an image, but a photographic plate or a photographic film may be used instead.
Moreover, you may perform the method of this invention with respect to the continuous label continuous body not only to the continuous label continuous body 1 joined. When X-rays are irradiated to a continuous label continuum, the connecting member cannot be detected, so it can be confirmed that there are no joints (that is, it is confirmed that the number of joints is zero. it can).
