Description

  The present invention relates to an apparatus for processing an adhesive label having an adhesive layer on one side and attached to a strip-shaped release liner, and particularly an adhesive label in which an unnecessary strip is formed in an inner area of a label main body by punching. The present invention relates to a label processing apparatus that removes only the extracted piece while leaving the label main body on the peeling liner.

  Conventionally, adhesive labels are widely attached to a strip-shaped release liner with an interval so that an adhesive label can be automatically attached to an object to be attached, but this type of adhesive label is adhesive on one side. After the strip-shaped base material on which the layer is formed and the release liner are bonded together, printing is performed on the surface of the base material, and then the base material is punched into a predetermined shape by die cutting.

  If the manufacturing method is shown and demonstrated in FIG. 9, S is a peeling liner and B is a label base material bonded together to the peeling liner S. FIG. As shown in FIG. 9B, a punching line dc is engraved on the label base material B by punching, and the inside of the label base material B is used as an adhesive label for practical use.

  The outside of the punching line dc is an unnecessary portion t that is continuous in a frame shape, but when the unnecessary portion t remains on the peeling liner S, the label body L is automatically pasted on the object to be adhered. Therefore, the unnecessary portion t is removed after the label base material B is punched out, and only the label main body L is left on the peeling liner S as shown in FIG.

  Here, the removal of the unnecessary portion t is generally performed by continuously winding the unnecessary portion using a winding roller (for example, Patent Document 1).

Japanese Patent Laid-Open No. 5-124136

  However, in the method of punching the label base material bonded to the release liner and providing the label main body with a predetermined shape on the release liner at a predetermined interval, the yield is reduced and unnecessary portions formed around the label main body. Therefore, productivity is also reduced. In addition, if the interval between the label bodies is narrowed to improve the yield, not only will unnecessary parts break during the removal process and the removal will not be performed efficiently, but the label body will be automatically attached to the target product by the end user of the label. When this is done, there is a concern that two label bodies will be fed out simultaneously.

  Furthermore, when the label base material is punched during the production of the pressure-sensitive adhesive label, the release liner existing underneath the cut liner enters, and the adhesive forming the pressure-sensitive adhesive layer of the label base material is pushed into the line, resulting in this. When the label main body is automatically applied, the label main body does not peel off from the peeling liner, and a label end user sometimes complains.

  The used release liner from which the label body has been completely peeled is disposed of by the end user without being reused.

  The present invention has been made in view of the circumstances as described above, and its object is to reduce the loss of raw materials related to adhesive labels, improve yield and production efficiency, and promote resource recycling.

In order to achieve the above object, the present invention
A plurality of label bodies that have an adhesive layer on the back surface and can be separated by a punching line are affixed to the strip-shaped release liner wound around the core, and each of the label bodies passes through the punching line. And providing a label roll characterized by being continuously arranged in the length direction of the release liner.

Further, it is attached to a first stripping liner that has an adhesive layer on the back surface and is continuous in a strip shape, and is detachable by a punching line, and the length of the first stripping liner through the punching line Label transfer device for transferring and pasting the label body to a second release liner that is continuous in a strip shape different from the first release liner at a predetermined interval based on the label bodies that are continuously arranged in the direction And
A first transfer means for transferring the first release liner; a label peeling portion for bending the first release liner transferred by the first transfer means into an acute angle and peeling the label body from the release liner; A label transfer sticking part provided in the vicinity of the label peeling part and a second peel passed through the label transfer sticking part to take off the label body peeled and protruded from the first peeling liner by the label peeling part And a second transfer means for transferring the liner at a higher speed than the first release liner.

Furthermore, it is affixed to the 1st peeling liner which has an adhesive layer in the back surface, and is strip | belt-shaped, and is detachable with a punching line, The length of said 1st peeling liner via the punching line Label transfer based on label bodies that are continuously arranged in the direction, and the label body is transferred and pasted at a predetermined interval to a second release liner that is continuous in a strip shape different from the first release liner. Device,
A first transfer means for intermittently feeding the first release liner at a constant pitch, and a first release liner intermittently fed by the first transfer means are bent at an acute angle to peel the label body from the release liner. A label peeling portion to be protruded, a label transfer sticking portion provided in the vicinity of the liner peeling portion, and a label transfer sticking portion for passing the label body peeled and protruded from the first peeling liner by the label peeling portion are passed through the label transfer sticking portion. And a second transfer means for intermittently feeding the second peeling liner to be intermittently fed at a feed pitch larger than that of the first peeling liner.

  In the above apparatus, the first transfer means has a liner take-up portion that winds up the first release liner from which the label main body has been peeled downstream of the label peeling portion, and the second transfer means is a label transfer sticker. A liner supply unit that rotatably holds a second release liner wound in a roll shape on the upstream side of the part, and a second release liner on which the label main body is attached on the downstream side of the label transfer application unit as a product roll And a product take-up unit for taking up the product.

  The label transfer pasting portion is characterized by comprising a liner receiver that supports the second release liner, and a pressure roller that presses the label main body against the second release liner opposite to the liner receiver.

Furthermore, the present invention is attached to a first stripping liner that has an adhesive layer on the back surface and is continuous in a strip shape, and is separated so as to be separable by a punching line, and the first peeling is performed via the punching line. Based on the label main body continuously arranged in the length direction of the liner, the label main body is transferred to the second release liner continuous in a strip shape different from the first release liner at a predetermined interval. It is a method of sticking,
While transporting the first release liner along a predetermined path, a part of the label body is bent at an acute angle and the label main body is peeled and protruded one by one from the release liner.
While the second release liner is transported at a higher speed than the first release liner along a path different from that of the first release liner, the label main body is at a position where the label main body is released from the first release liner. A second release liner on which the label main body is pasted by transferring and pasting the label main body peeled and protruded from the first release liner to the second release liner one by one at a predetermined interval through the second release liner. A label transfer method characterized in that the product is wound as a product roll.

  In addition, the present invention provides a label transfer method characterized in that a second recovery liner that is recovered from a user of a product roll in a state where the label main body has been completely peeled is used.

  According to the label roll of the present invention, since the label main body is continuously arranged in the length direction of the release liner via the punching line, an unnecessary portion continuous in a frame shape is formed around the label main body. Therefore, all of the label base material can be used as the label body. Therefore, the yield can be greatly improved, and the production efficiency is improved because no unnecessary part removing step is required.

  In addition, it is not necessary to form the unnecessary parts in a frame shape in consideration of the removal efficiency of unnecessary parts as in the past, and the label body can be cut off by inserting the punching line in the transverse direction of the label base material. Since the separation can be performed, the number of punched portions of the label base material is reduced, and as a result, the lines formed on the release liner can be reduced. Therefore, the release liner is hardly damaged and can be used repeatedly.

  In addition, according to the apparatus and the method of the present invention, the label main body continuously arranged in the length direction of the release liner (first release liner) through the cut line as described above is provided in the first The label can be efficiently transferred to a release liner (second release liner) different from the release liner, and the label main body is transferred and affixed to the second release liner at a predetermined interval. The main body can be automatically and satisfactorily applied to the object to be applied while being peeled from the second release liner one by one.

  Also, since the label main body is transferred to a large number of end users while being transferred and pasted to the second release liner, the first release liner can be returned from the label maker to the base paper maker and used as a papermaking raw material. Since there are fewer manufacturers than end users, it is expected that the first release liner can be recovered with a high recovery rate, and the recovery path can be shortened to reduce the recovery cost, thereby promoting resource recycling.

  On the other hand, the second release liner can be used repeatedly between the label maker and the end user, and the second release liner is not formed with lines due to die cutting. It does not break and can maintain a predetermined strength even after repeated use.

  Hereinafter, the present invention will be described in detail with reference to the drawings. First, FIG. 1 shows a label roll according to the present invention. As is clear from FIG. 1, the label roll R1 has a strip-shaped release liner S1 (first release liner) wound around a cylindrical core C1 as a support, and a plurality of label bodies having a predetermined shape thereon. L is attached. The release liner S1 is a highly flexible mount having a main surface coated with a release agent such as silicone, and a label main body L is attached to the main surface on one side. However, the front end portion of the release liner S1 is a blank portion m where the label main body L does not exist over a certain length.

  On the other hand, the label main body L is made of a relatively hard synthetic paper that is more tensioned than the release liner S1, and an adhesive layer formed by applying an adhesive on the back surface (the surface corresponding to the release liner S1). Is formed. In particular, as is clear from FIG. 2, the label main body L is separated by a punching line dc extending in the width direction of the peeling liner S1, and each label main body L,... Is peeled off via the punching line dc. The liner S1 is continuously arranged in a line with no gap in the length direction.

  The label roll R1 as described above is bonded to a release liner S1 having the same width or wider than that of a strip-shaped label base material B on which printing is performed on the front surface and an adhesive layer is formed on the back surface. It is manufactured by winding the release liner S1 around the core C1 while putting a punching line dc into the label base B and subdividing the label base B as a plurality of label bodies L,. The unnecessary portion other than the label main body L is not formed on the label base material B, and therefore, the unnecessary operation of removing the unnecessary portion in the related art is not performed. For this reason, according to the label roll R1, it is possible for the label maker to improve the yield and the production efficiency and to obtain the advantage that the manufacturing cost can be suppressed. However, in an aspect in which the label main bodies L are connected without gaps, the existing label sticking device is not compatible with the end user who uses the label main body L, and there are problems such as two label main bodies L being stuck on the sticking target. .

  Accordingly, the present invention provides an apparatus and a method for transferring and pasting the label main body L attached to the release liner S1 to the release liner S2 (second release liner) different from the release liner S1 at a predetermined interval. To do.

  FIG. 3 is a schematic view showing a configuration example of the label transfer apparatus. In FIG. 3, reference numeral 1 denotes a label supply unit that rotatably holds a label roll R1, and this label supply unit 1 includes a rotary shaft 11 that is passed through a core C1 of the label roll R1. A chuck (not shown) for fixing the roll R1 is provided. The rotating shaft 11 is applied with a braking force (rotational load) from a brake device (not shown), thereby preventing inertial rotation of the rotating shaft 11 and the label roll R1.

  Then, the release liner S1 unwound from the label roll R1 is sent to the label peeling unit 3 through the plurality of tension rollers 2, and further, the liner roll RS1 is passed through the label peeling unit 3 by the liner winding unit 4 at the downstream end. It is set as the structure wound up by the core C2.

  The label peeling unit 3 peels a label main body L (not shown in FIG. 3) attached to the peeling liner S1 from the peeling liner S1, which is a blade made of a metal plate or the like on a device frame (not shown). The separation liner S1 is bent abruptly (in an acute angle form in this example) to the opposite side of the surface of the label main body L at one end edge of the blade 31.

  As described above, the label main body L is formed of a material harder than the release liner S1, and for this reason, when the release liner S1 is bent at one edge of the blade 31 and transferred to the downstream side, the label main body L is folded. It goes straight without bending and is peeled from the peeling liner S1 in order from the tip, and protrudes beyond the edge of one end of the blade 31.

  Further, as shown in FIG. 3, a pair of feed rollers 5a and 5b are provided between the label peeling unit 3 and the liner winding unit 4 with the peeling liner S1 interposed therebetween and drawn into the liner winding unit 4 side. Provided. The feed rollers 5a and 5b are drive rollers that are rotationally driven by a control motor (not shown), which transports the peeling liner S1 along a predetermined path in cooperation with the label supply unit 1 and the liner winding unit 4. The first transfer means is configured. The peeling liner S1 is continuously fed at a constant speed by the rotational driving of the feed rollers 5a and 5b, or intermittently fed at a constant pitch. Note that the feed pitch when intermittently feeding the release liner S1 coincides with the length of the label body L attached to the release liner S1 (the distance between the two punching lines dc and dc).

  The liner winding unit 4 includes a cantilevered rotating shaft 41 that is passed through the winding core C2, and a chuck (not shown) that fixes the winding core C2 is provided on the rotating shaft 41. The rotary shaft 41 is driven to rotate by a control motor different from the feed rollers 5a and 5b, but the amount of rotation changes according to the winding amount of the peeling liner S1 (as the diameter of the liner roll RS1 increases). Thus, the feed amount of the release liner S1 by the feed rollers 5a and 5b and the winding amount by the liner winding unit 4 are controlled to coincide with each other.

  On the other hand, the release liner S2 (second release liner) is supplied from the liner supply unit 6 to a position where the leading end of the label main body L protruding beyond the one end edge of the blade 31 constituting the label peeling unit 3 is approached. The label transfer sticking part 7 is provided. The release liner S2 is wound around a core C3 as a liner roll RS2, and is configured to be rotatably held by the liner supply unit 6.

  The liner supply unit 6 includes a rotary shaft 61 that is passed through the core C3 of the liner roll RS2, and a chuck (not shown) that fixes the core C3 to the rotary shaft 61 is provided. In addition, a braking force (rotational load) is applied to the rotating shaft 61 from a brake device (not shown), thereby preventing inertial rotation of the rotating shaft 61 and the liner roll RS2.

  Then, the release liner S2 unwound from the liner roll RS2 is sent to the label transfer pasting portion 7, and further passed through the label transfer pasting portion 7 as a product roll R2 by the product winding portion 8 at the downstream end. The structure is wound around C4.

  The label transfer pasting portion 7 is composed of a flat liner receiver 71 disposed with a predetermined gap G between the label 31 and the blade 31, and a pressure contact roller 72 facing the liner receiver 71, and the liner receiver 71. The peeling liner S <b> 2 supplied from the liner supply unit 6 is passed between the contact roller 72 and the pressure roller 72. Then, the label main body L that is peeled and protruded from the release liner S1 onto the liner receiver 71 across the blade 31 and the liner receiver 71 is transferred and pasted to the release liner S2, and the label main body L is attached to the release liner S2 by the pressure roller 72. It is set as the structure pressed firmly with respect to it. FIG. 4 shows a state in which the label main body L transferred and pasted to the release liner S2 is pressed by the pressure roller 72. Here, the pressure roller 72 is a free roller that rotates by contact with the release liner S2.

  Further, as shown in FIG. 3, a pair of feed rollers 9a and 9b that draws the release liner S2 between the label transfer sticking portion 7 and the product take-up portion 8 and pulls it to the product take-up portion 8 side. Is provided. The feed rollers 9a and 9b are drive rollers that are rotationally driven by a control motor (not shown), which moves the peeling liner S2 along a predetermined path in cooperation with the liner supply unit 6 and the product winding unit 8. The second transfer means is configured.

  The release liner S2 is continuously fed at a constant speed by the rotational driving of the feed rollers 9a and 9b, or intermittently fed at a constant pitch. However, the transfer of the release liner S2 is performed at a higher speed than the release liner S1. Specifically, when the peeling liner S1 is continuously fed at a constant feeding speed, the peeling liner S2 is continuously fed at a higher speed. For example, when the peeling liner S1 is continuously fed at 1 m / sec, the peeling liner S2 is continuously fed at 2 m / sec. When the release liner S1 is intermittently fed at a feed pitch corresponding to the length of the label main body L as described above, the release liner S2 is intermittently fed at a feed pitch 1.5 to 2 times that of the release liner S1. .

  In this way, the release liners S1 and S2 are continuously fed or intermittently fed. In either case, the release liner S2 is transferred at a higher speed than the release liner S1, and as shown in FIG. The label main body L that is continuously applied to the release liner S1 can be transferred and applied to the other release liner S2 at a predetermined interval. The interval can be arbitrarily adjusted by the feed amount (speed difference) of the release liners S1 and S2.

  Here, the release liner S2 to which the label body L is transferred and pasted is wound around the core C4 as the product roll R2 by the product winding unit 8 as described above, but the product winding unit 8 is wound around the core C4. It includes a cantilevered rotating shaft 81 that is passed through, and a chuck (not shown) that fixes the winding core C4 to the rotating shaft 81. The rotation shaft 81 is driven to rotate by a control motor different from the feed rollers 9a and 9b, and the amount of rotation changes according to the amount of winding of the release liner S2 (as the diameter of the product roll R2 increases). Accordingly, the feed amount of the release liner S2 by the feed rollers 9a and 9b is controlled to coincide with the take-up amount by the product winding unit 8.

  FIG. 6 shows a product roll R2 as a finished product, which is supplied to the end user of the label. And an end user sets the said product roll R2 to the existing label sticking apparatus, and the label main body L is peeled one by one from the peeling liner S2 by the label sticking apparatus, and is stuck on the sticking object. The release liner S2 remaining after the label main body L is completely peeled off is collected as a liner roll RS2 from the end user to the label maker, and this is set by the label maker in the liner supply unit 6 of the label transfer device to transfer the label main body L. Used repeatedly for sticking. The other liner roll RS1 is collected from the label maker to the base paper maker and used as a papermaking raw material.

  Although the application example of the present invention has been described above, the label main body L is not limited to a rectangle, and may be a curved label main body L divided by an arcuate punching line dc as shown in FIG. . In the above example, the label main body L is attached to the peeling liner S1 fed out from the label supply unit 1 in a state where the label main body L is preliminarily separated by the punching line dc. However, as shown in FIG. While the cutter roller CR is provided between the supply unit 1 and the label peeling unit 3, a strip-shaped label base material is pasted on the peeling liner S1 fed out from the label supply unit 1, and the label peeling unit is attached to the label base material. 3 may be punched by a cutter roller CR on the upstream side. Even in this case, the label main body is continuously arranged in the length direction of the peeling liner S1 via the punching line between the label peeling portion 3 and the cutter roller CR.
