Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method and apparatus for manufacturing a tack label.
[0002]
[Prior art]
As seal-type tack labels to be affixed to various products, wrapping paper, containers, packing boxes, etc., characters, figures, symbols, barcodes, etc. are printed on the surface of sheet materials formed from paper, etc. There is known one in which an adhesive layer is provided on the back surface of a sheet material. In the tack label, a release paper is pasted on the back surface so as to cover the pressure-sensitive adhesive layer before use (before sticking).
Therefore, in order to use (attach) this tack label, the release paper is peeled off from the back surface and the pressure-sensitive adhesive layer is pressed to the application position.
[0003]
Conventionally, in order to manufacture this type of tack label, the pressure-sensitive adhesive is uniformly applied to the back surface of the sheet material to provide a pressure-sensitive adhesive layer, but this process deals with a liquid or high-viscosity pressure-sensitive adhesive. For this reason, it has become environmentally wet, the apparatus becomes complicated, and it takes time for drying. Therefore, these have become a bottleneck in trying to achieve cost reduction and high operating efficiency.
Accordingly, the present applicant has come up with the idea that if the tack label 100 having the structure as shown in FIG. 6 is manufactured, the application of the adhesive to the sheet material 101 can be omitted in the manufacturing process.
[0004]
That is, the tack label 100 is attached to the outer edge portions 101a on both sides in the width direction of the front surface 102 of the sheet material 101 with the adhesive tape 104 extending in half along the longitudinal direction, and the back surface of the sheet material 101. From the side, the release paper 106 is pasted so as to cover the adhesive tape 104 (adhesive surface) protruding from the outer edge portion 101 a of the sheet material 101. Here, the sheet material 101 and the release paper 106 are also originally formed in a tape shape like the adhesive tape 104, and the whole is cut into a predetermined length after bonding.
[0005]
[Problems to be solved by the invention]
In the method of manufacturing the tack label 100 created by the applicant as described above, the adhesive tape 104 wound around the roll shape and the release paper 106 wound around the roll shape are separately prepared, These are brought to the bonding process with the sheet material 101 and used.
In this case, particularly in the case of the adhesive tape 104, waste is generated when dust adheres to the adhesive surface at the unwinding portion from the roll portion or when a sticking error occurs. Thus, there is a tendency that a difference is easily generated between the consumption of the adhesive tape 104 and the consumption of the release paper 106.
[0006]
For this reason, the roll body of the adhesive tape 104 and the roll body of the release paper 106 need to be managed separately, which may cause some difficulty in handling.
The present invention has been made in view of the above circumstances, and is attached to the sheet material in a state where the adhesive tape protrudes to the outer edge portions on both sides in the width direction of the surface, and from the back surface side of the sheet material, When manufacturing a tack label by sticking a release paper with the adhesive tape (adhesive surface) protruding from the outer edge of the material, the management of the adhesive tape and the release paper is facilitated, handling is improved, and It is an object of the present invention to provide a tack label manufacturing method and manufacturing apparatus that can achieve low cost and high operating efficiency.
[0007]
[Means for Solving the Problems]
In the present invention, in order to achieve the above object, the following technical means are taken.
That is, the manufacturing method of the tack label according to the present invention includes a sheet material, an adhesive tape having only one surface attached in an protruding state along the outer edge of the surface side of the sheet material, and the back surface of the sheet material. A method for manufacturing a tack label having a release paper that is attached in a state of covering the adhesive surface of the adhesive tape protruding from the outer edge of the adhesive tape, wherein the release paper is previously applied to the adhesive surface of the adhesive tape. Prepare a tape-like seal that is bonded to the entire surface.
[0008]
And in this tape-like seal, the adhesive tape and the release paper are once peeled to form an open space between them.
Further, the outer edge of the sheet material is sandwiched between the adhesive tape and the release paper in the open space with the front side facing the adhesive tape and the back side facing the release paper. At this time, the entire area of the intermediate position is not partitioned by the sheet material, and a region where the adhesive tape and the release paper directly overlap is left to some extent.
In this state, the pressure-sensitive adhesive tape and the release paper are pressed against each other in a direction to close the open space, whereby the pressure-sensitive adhesive tape is stuck to the surface of the sheet material in a protruding state.
[0009]
Further, the release paper is pasted on the adhesive surface of the adhesive tape in a state where the release paper is straddled between the back surface of the sheet material and the adhesive tape in a protruding state.
If it does in this way, an adhesive tape and a release paper will always be handled as what comprises a tape-shaped seal | sticker by the relationship of 1 to 1, and will be consumed simultaneously inevitably.
In addition, since the supply of the adhesive tape and the release paper to the sheet material is necessarily synchronized, the control for synchronizing the supply speeds of the adhesive tape and the release paper is unnecessary. However, handling is facilitated.
[0010]
The tape-shaped seal exhibits a long tape shape by forming the adhesive tape and the release paper in the same length (same length) as a long tape shape that extends multiple times the tack label. Can be formed as In this case, the tape-shaped seal may be wound around the roll shape.
If it does in this way, the roll part of this tape-shaped seal | sticker can be used as a thing which unwinds a tape-shaped seal | sticker from a roll form as what moves relatively between sheet materials.
[0011]
With this usage, handling of the tape-shaped seal itself is also facilitated. Furthermore, the tape-like seal (adhesive tape and release paper) can be easily supplied to the sheet material.
Note that the fact that the adhesive tape and release paper are multiple times the length of the tack label does not mean an integral multiple of the tack label, but it is long enough to produce multiple tack labels. .
When the sheet material is moved in the relative movement between the roll portion of the tape-shaped seal and the sheet material, the roll portion of the tape-shaped seal is unwound in the direction to the side of the movement path of the sheet material. It is arranged in a direction where the tip of the head becomes a moving passage and is held rotatably. And as above-mentioned, unwinding of a tape-shaped seal | sticker and formation of the open space by peeling with an adhesive tape and a release paper shall be performed.
[0012]
Then, each of the adhesive tape and the release paper is then folded once so as to be directed in the direction opposite to the moving direction of the sheet material, and then the moving direction of the sheet material. While adding two folds that are folded back so as to be directed in the same direction, the sheet is supplied to both front and back side positions overlapping each other with respect to the outer edge portion of the sheet material moving through the moving path.
And what is necessary is just to make it carry out opposing press with an adhesive tape and a release paper after that.
[0013]
As described above, by adopting a supply method in which the adhesive tape and the release paper are folded twice, there is an advantage that the guide, the direction change, and the alignment with respect to the sheet material can be performed in a compact space. In addition, the adhesive surface of the adhesive tape is necessarily directed to the surface of the sheet material, and the release paper is necessarily attached to the adhesive surface of the adhesive tape on the back surface of the sheet material. Will be directed to.
On the other hand, in the tack label manufacturing apparatus according to the present invention which can be used in such a manufacturing method, a moving path for moving a strip-like long sheet material along its longitudinal direction, and at least one side of the moving path. And a guiding means provided between the tape unwinding portion and the moving passage.
[0014]
The tape unwinding portion is a place for holding the tape-shaped seal wound around the roll shape so that the tip in the unwinding direction faces the moving path and is rotatable.
Further, the guiding means includes a peeling portion for separating the single-sided adhesive tape constituting the tape-shaped seal and the release paper affixed to the adhesive surface of the adhesive tape, and the adhesive tape and the release paper, respectively. A direction changing part that guides to both sides of the front and back that overlap the outer edge part of the sheet material while making the sheet material accompany the moving direction, and an adhesive tape and release paper are directed to the outer edge part of the sheet material, respectively. And a bonding portion that is pressed against each other.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 3 show an embodiment of a method for manufacturing a tack label according to the present invention and a manufacturing apparatus 1 that can be used therefor.
FIG. 4 shows a tack label 100 obtained by the manufacturing method and the manufacturing apparatus 1. As described above, the tack label 100 is based on the idea of the applicant of the present invention. The tack label 100 adheres only to the sheet material 101 and one side of the sheet material 101 that is pasted along the outer edge portion 101a on the front surface 102 side. It has an adhesive tape 104 as a surface 103 and a release paper 106 that is pasted in a state of covering the adhesive surface 103 of the adhesive tape 104 protruding from the back surface 105 side of the sheet material 101 at its outer edge.
[0016]
In FIG. 4, the adhesive tape 104 and the release paper 106 are provided on two opposite sides of the sheet material 101, but may be provided only on one side of the sheet material 101 as shown in FIG. In some cases, it may be provided on three or all four sides (not shown).
In the manufacturing apparatus 1 for manufacturing such a tack label 100, the moving path 2 for moving the sheet material 101, the tape unwinding section 3 provided on the side of the moving path 2, and these tape unwinding sections. 3 and a guiding means 4 provided between the moving passage 2 and the moving path 2.
[0017]
The moving path 2 keeps a predetermined tension with respect to the sheet material 101 and feeds the sheet material 101 without causing wrinkles. The moving path 2 is driven and driven at a plurality of locations along the feeding direction. Conventionally known appropriate transporting equipment (not shown) such as a pinch roller for tension and a dancer roller for tension adjustment is provided.
As the sheet material 101, it is initially assumed that it is formed in a long strip shape that extends over a plurality of times the tack label 100 (not necessarily an integral multiple), and preferably wound around a roll shape. Prepare it.
[0018]
Therefore, the sheet material 101 may be automatically unwound from the roll body as necessary on the conveyance start end side of the movement path 2.
The tape unwinding portion 3 is provided on both sides in the width direction with respect to the movement path 2 when the tack label 100 shown in FIG. It is provided on at least one side in the width direction.
The tape unwinding section 3 is for supplying the adhesive tape 104 and the release paper 106 toward the sheet material 101 conveyed in the movement path 2. Here, the adhesive tape 104 and the release paper 106 In addition, a tape-shaped seal 110 that is previously bonded to each other is used.
[0019]
Both the adhesive tape 104 and the release paper 106 constituting the tape-shaped seal 110 are formed in a long tape shape that extends a plurality of times (not necessarily an integer multiple) of the tack label 100. Furthermore, they have the same length and the same width. Therefore, the adhesive surface 103 of the adhesive tape 104 is entirely covered with the release paper 106.
Therefore, when this tape-shaped seal 110 is wound around a roll shape, unnecessary sticking does not occur between the windings, and dust or the like does not adhere to the adhesive surface 103 of the adhesive tape 104.
[0020]
The tape-shaped seal 110 is prepared in a state of being wound around a roll shape.
For this reason, the tape unwinding section 3 holds the tape-shaped seal 110 wound around the roll shape so that the tip in the unwinding direction faces the moving passage 2 and is rotatable. It has become. If necessary, unwinding drive means (not shown) may be provided.
The guiding means 4 includes a peeling part 10, an adhesive tape turning part 11, a release paper turning part 12, and a bonding part 13.
[0021]
The peeling part 10 is the place where the adhesive tape 104 and the release paper 106 are peeled from each other with respect to the tape-shaped seal 110 unwound by the tape unwinding part 3, thereby forming an open space 14 between them.
In the peeling unit 10, when the tape-shaped seal 110 is first set, the adhesive tape 104 and the release paper 106 are peeled into a Y shape by the operator's hand, and the adhesive tape is used in accordance with consumption on the other side. By simply applying a pulling action to each of the 104 and the release paper 106 with substantially the same force, the peeling phenomenon is naturally continued thereafter.
[0022]
However, if necessary in the sense of giving further certainty, a wedge member or a roller for diversion (both not shown) may be provided at the separation position between the adhesive tape 104 and the release paper 106.
The adhesive tape redirecting portion 11 is where the adhesive tape 104 is guided to a position where it overlaps the outer edge portion 101a of the surface 102 of the sheet material 101, and is made to accompany the moving direction of the sheet material 101.
At this time, first, folding is performed so that the adhesive tape 104 is turned in the direction opposite to the moving direction of the sheet material 101 (the right direction in FIG. 2), and then the adhesive tape 104 is moved by the movement of the sheet material 101. Two-folding is performed so as to be directed in the same direction as the direction (left direction in FIG. 2).
[0023]
As shown in FIG. 3, the 1-fold and 2-fold patterns may be obtained by covering the adhesive tape 104 with the thin plate-like folding guides 15 and 16. Here, the folding guide 16 for two-folding comes into contact with the adhesive surface 103 of the adhesive tape 104, but the contact force between the adhesive tape 104 and the folding guide 16 is not so strong, so that there is not much problem with respect to adhesion. Does not occur.
However, the surface of the turn-back guide 16 is subjected to Teflon coating, embossing, etc., or the shape of the turn-back guide 16 is changed from a thin plate to a roller shape to prevent the occurrence of adhesion. It can also be done actively.
[0024]
Thus, by folding twice, the adhesive tape 104 can be supplied to the surface side position that reasonably overlaps the outer edge portion 101a of the sheet material 101 that moves in the movement path 2. Further, the adhesive surface 103 of the adhesive tape 104 is necessarily directed to the surface 102 of the sheet material 101.
The release paper redirecting unit 12 is configured to guide the release paper 106 to a position overlapping the outer edge portion 101 a of the back surface 105 of the sheet material 101, and to bring the release paper 106 into the accompanying state in the moving direction of the sheet material 101.
[0025]
At this time, first, folding is performed so that the release paper 106 is turned in the direction opposite to the movement direction of the sheet material 101 (the right direction in FIG. 2), and then the release paper 106 is moved by the movement of the sheet material 101. Two-folding is performed so as to be directed in the same direction as the direction (left direction in FIG. 2).
For the 1st and 2nd diffractions, the folded guides 15 and 16 having an appropriate shape may be used, as in the case shown in FIG.
In this way, by turning back twice, the release paper 106 can be supplied to the rear surface side position that easily overlaps the outer edge portion 101a of the sheet material 101 moving in the movement path 2. In addition, the release paper 106 is inevitably directed toward the back surface 105 of the sheet material 101 with respect to the adhesive surface 103 of the adhesive tape 104.
[0026]
If the incident angle in the supply direction of the tape-shaped seal 110 with respect to the moving path 2 (the unwinding advance direction from the roll shape) is 90 °, the adhesive tape 104 and the release paper 106 are viewed from this supply direction. The above-mentioned one-folding is called “90 ° folding”, and the two-folding of the adhesive tape 104 and the release paper 106 is called “180 ° folding” as viewed from this one-folding. Of course, such an angular situation is not limited at all.
The bonding portion 13 is a place where the adhesive tape 104 and the release paper 106 are pressed against each other toward the outer edge portion 101 a of the sheet material 101.
[0027]
Specifically, a pinch roller 18 is provided so as to sandwich the sheet material 101 conveyed through the movement path 2 from both the front and back surfaces, and the upper pinch roller 18 and the surface 102 of the sheet material 101 are connected to each other. The adhesive tape 104 is passed between them, and at the same time, the release paper 106 is passed between the lower pinch roller 18 and the back surface 105 of the sheet material 101.
Next, the manufacturing method according to the present invention will be described based on the usage status of the manufacturing apparatus 1.
[0028]
In the moving path 2, the sheet material 101 is conveyed while being kept under a predetermined tension and without wrinkles, and the tape-shaped seal 110 is supplied toward the sheet material 101 from both sides (or one side) in the width direction.
At this time, while the sheet material 101 is unwound from the roll shape, it is first peeled off from the adhesive tape 104 and the release paper 106 at the peeling portion 10 of the guiding means 4 to form an open space 14 therebetween.
Then, with the open space 14 held, the adhesive tape 104 is guided to the outer edge portion 101a on the front surface 102 side of the sheet material 101, and the release paper 106 is guided to the outer edge portion 101a on the rear surface 105 side of the sheet material 101. Guide to.
[0029]
In the course of this guidance, the adhesive tape turning portion 11 and the release paper turning portion 12 overlap the outer edge portion 101a of the sheet material 101, and the relationship between the front and back surfaces of the sheet material 101 and the adhesive tape 104. And the relationship between the front and back surfaces of the release paper 106 is made uniform.
As a result, the adhesive tape 104 and the release paper 106 are parallel to each other with the open space 14, and the outer edge portion 101a of the sheet material 101 is sandwiched between the intermediate positions thereof.
[0030]
In the next bonding section 13, the adhesive tape 104 and the release paper 106 pass through the pinch roller 18 and are pressed against each other in the direction to close the open space 14 (vertical direction in FIG. 1). The adhesive tape 104 is attached to the front surface 102 of the sheet 101 in a protruding state, and the adhesive surface 103 of the adhesive tape 104 and the back surface 105 of the sheet material 101 are in the protruding state to the rear surface 105 of the sheet material 101. The release paper 106 is pasted in a state of straddling.
In this way, the adhesive tape 104 and the release paper 106 are always consumed at the same time while maintaining a one-to-one correspondence, that is, as the tape-shaped seal 110.
[0031]
Here, the sheet material 101, the adhesive tape 104, and the release paper 106 will be described in more detail.
The sheet material 101 is made of an appropriate material such as paper, resin-coated paper, resin sheet, or cloth, and characters, figures, symbols, barcodes, etc. are displayed or written on the surface 102 by printing or the like. It is assumed to be plain. Printing or the like may be performed before or after the adhesive tape 104 or release paper 106 is attached to the sheet material 101.
[0032]
The material of the adhesive tape 104 is not particularly limited as long as the adhesive is preliminarily attached to one surface of the tape material serving as the base material. For example, paper, cloth, resin, metal foil or the like can be used as the tape material, and various types of adhesives such as rubber can be used as the adhesive. Appearance can also be improved by using a transparent resin-based tape material. Of course, a commercially available adhesive tape 104 can be used as it is.
The release paper 106 is paper, resin-coated paper, resin sheet, or the like. In short, the release paper 106 can be attached to the adhesive surface 103 of the adhesive tape 104 and can be peeled relatively easily. The material is not particularly limited as long as the material does not leave a deposit on 103 (that is, can be peeled cleanly).
[0033]
On the other hand, in the tack label 100 obtained by bonding the sheet material 101, the adhesive tape 104, and the release paper 106, only about half of the width dimension of the adhesive tape 104 is applied to the sheet material 101, and the remaining approximately the width. In contrast, the release paper 106 has the same width as the adhesive tape 104 and is positioned so as to match the adhesive tape 104.
That is, about half of the width dimension of the release paper 106 is kept attached to the sheet material 101 side via the adhesive tape 104, but the other half of the width dimension of the release paper 106 is on the sheet material 101 side. Not sticking. Therefore, the release paper 106 can be easily peeled off from the sheet material 101 by inserting a fingertip from the side not attached to the sheet material 101 side.
[0034]
Note that the size of the adhesive tape 104 and the release paper 106 as well as the sheet material 101, the amount of pasting, the thickness, and the like are not limited at all.
The present invention can be variously modified in addition to the above embodiment.
For example, in the tape-shaped seal 110 (adhesive tape 104 and release paper 106), the width direction dimension is slightly larger than that of the sheet material 101, and the entire surface of the sheet material 101 is covered with the adhesive tape 104. On the other hand, it is also possible to apply the tape so as to protrude from the outer edge portion 101a.
[0035]
【The invention's effect】
As is apparent from the above description, in the method and apparatus for manufacturing a tack label according to the present invention, a sheet is attached to the sheet material with the adhesive tape protruding from the outer edge portions on both sides of the surface in the width direction. Management of adhesive tape and release paper is facilitated when manufacturing a tack label by attaching release paper in a state of covering the adhesive tape (adhesive surface) protruding from the outer edge of the sheet material from the back side of the material. As a result, handling is improved, and further cost reduction and high operating efficiency can be achieved.
