JP 2009-219583 A

  As shown in FIG. 6, there is a pressure-sensitive adhesive covering that is obtained by laminating a product separator 3 made of hard plastic on an object 2 to be stuck. The adherend 2 is formed by laminating an adhesive layer 2b containing a drug on the entire surface of one side of the support 2a, and the adhesive layer 2b and the product separator 3 are overlaid. The product separator 3 has one or two back splits 3a in a corrugated shape so as to be easily separated. The spine 3a has been conventionally inserted by half-cutting the blade into the product separator original in a state where the object 2 is sandwiched between the product separator original and the support original.

  However, the pressure-sensitive adhesive covering body is also required to be thinned, and the product separator raw material may be formed as thin as about 15 to 20 μm. When the back of the product separator is cut with a blade, the blade damages and damages the support material, and an adhesive layer is sandwiched between the product separator material and the support material. In this state, the support 2a cannot be transported to the downstream side, and even if it can be manufactured, the support of the adhesive covering is in a damaged state. Sometimes it was a good product. This cannot be solved even by the apparatus for manufacturing an adhesive covering described in Japanese Patent Application No. 1-101.

  Then, this invention makes it a subject to provide the manufacturing apparatus of the adhesive coating | coated body which was able to manufacture an adhesive coating | coated body even if it puts a back in the product separator original fabric.

  The apparatus for producing an adhesive covering according to the present invention includes a first vacuum drum in which an original material to be stuck in which an adhesive layer is laminated on the entire surface of one side of a belt-like support is partially wound with the adhesive layer outside. A first die roll for forming an adherend in a state in which the adhesive layer is partially wound around the first vacuum drum and the support is in a state of being individually serialized; A second vacuum drum in which the product separator original fabric is partially wound, and a second vacuum drum for placing a longitudinal split in the strip-shaped product separator original fabric partially wound on the second vacuum drum A die roll is provided, the first vacuum drum and the second vacuum drum are arranged so as to contact each other with the object to be pasted and the product separator raw material separated from the back, and the first vacuum drum is covered. Rotating in one direction while adsorbing with a weak suction force that does not cause attachments to fall, the second vacuum drum is slightly faster than the first vacuum drum, and opposite to the first vacuum drum It is characterized in that it is rotated in the direction and the object to be pasted is transferred to the product separator at a certain interval.

  According to this apparatus for producing an adhesive covering, the object to be adhered is formed in a state where it is individually serially connected from the material to be adhered by the first die roll and is not damaged. The position where the first separator drum and the second vacuum drum are in contact with each other, while the product separator raw fabric advances with the back being split by the second die roll. Then, the article to be stuck is transferred to the original product separator.

  Since the adhesive layer has an adhesive layer facing outward and is attracted to the first vacuum drum with a weak suction force that does not drop, the first vacuum drum and the second vacuum drum are in contact with each other. At a certain position, when it comes into contact with the back-divided product separator original fabric, it is transferred to the product separator original fabric split-back by the adhesive force of the adhesive layer.

  On the other hand, since the product separator blank is adsorbed by the second vacuum drum, it is partially wound around the second vacuum drum even if it is inserted in the back. Since the second vacuum drum rotates slightly faster than the first vacuum drum, the object to be stuck is transferred so as to be pulled by the product separator original, so that a constant interval is provided. Affixed to the product separator stock.

  In the adhesive covering body manufacturing apparatus according to the present invention, the first vacuum drum blows out air for pressing the object to be bonded to the product separator at a position where the object is transferred to the product separator original. It is preferable that it is made so.

  According to this apparatus for manufacturing an adhesive covering, the object to be adhered is pressed against the product separator original by air at a position where the object adhering to the first vacuum drum is transferred to the product separator original. It can be reliably transferred to the original product separator without proceeding while adhering to the first vacuum drum.

  Further, in the pressure-sensitive adhesive covering body manufacturing apparatus according to the present invention, the release separator is covered when the original paste is a release separator laminated on an adhesive layer laminated on the entire surface of one side of the support. It is preferable that a peeling means for peeling from the patch is arranged so as to contact the first vacuum drum across the material to be pasted upstream of the first die roll.

  According to this apparatus for producing an adhesive covering, when the original patch is a laminate of release separators, the peeling means can peel the release separator from the adhesive layer to expose the adhesive layer. In addition, even if the adhesive original fabric which laminated | stacked the release separator is the brittle or too sticky adhesive layer, it is supposed that it can be stored in a roll shape and can be let out from a roll.

  Moreover, it is preferable that the cutting | disconnection means which cut | disconnects the product separator original fabric in which the said to-be-adhered thing was transferred in the predetermined shape is provided in the manufacturing apparatus of the adhesive coating | coated body which concerns on the said this invention.

  According to this apparatus for producing an adhesive covering, the cutting means can cut the product separator raw material to produce a final product.

  ADVANTAGE OF THE INVENTION According to this invention, the adhesive coating body by which the support body is not damaged can be manufactured by providing the manufacturing apparatus of the adhesive coating body which transfers a to-be-adhered article to the product separator original fabric which was split apart. It becomes possible.

It is a schematic perspective view and a partial expanded sectional view of an adhesive covering.

  An embodiment of an apparatus for producing an adhesive covering according to the present invention will be described with reference to FIGS. 1 to 3. This apparatus for producing an adhesive covering is for producing an adhesive covering as shown in FIG. 6 from an article to be bonded 200 and a product separator original 300. The first vacuum drum 10 and the first A die roll 20, a second vacuum drum 30, and a second die roll 40 are provided.

  As shown in the partially enlarged cross-sectional view of FIG. 2, the material to be adhered 200 is formed by laminating an adhesive layer 202 on the entire surface of one side of a belt-like support 201, and laminating a release separator 203 on the adhesive layer 202. It has a layered structure and is fed out from the roll. Moreover, the product separator original fabric 300 is formed of a flexible hard plastic and is fed out from a roll.

  Then, the first vacuum drum 10 and the first die roll 20 are arranged so as to be in contact with each other through the material to be stuck 200 (exactly, the support 201 and the adhesive layer 202 from which the release separator 203 has been peeled off). ing.

  Further, the second vacuum drum 30 and the second die roll 40 are arranged so as to be in contact with each other with the product separator raw fabric 300 interposed therebetween. Further, the first vacuum drum 10 and the second vacuum drum 30 are arranged so as to be in contact with the material substrate 200 (the material 204 to be described later) and the product separator material 300 sandwiched therebetween. Yes.

  Then, the first vacuum drum 10 is partially wound (from 10 o'clock position to 3 o'clock position on the clock face in the drawing) with the original material 200 to be pasted in one direction (counterclockwise direction in the drawing). ). The original material 200 is partially wrapped around the first vacuum drum 10 such that the support 201 overlaps the side surface of the first vacuum drum 10 and the release separator 203 faces outward.

  Also, the first vacuum drum 10 has a large number of vent holes (not shown) formed on the side surfaces, and a hood 11 connected to suction means (not shown) for evacuating both ends of the first vacuum drum 10. Are provided with a plurality of communication holes 12, 12,... For communicating the vent hole and the hood 11. However, the hood 11 adsorbs only a part of the material to be pasted 200 that overlaps the side surface of the first vacuum drum 10 (in the drawing, the position of the clock face from 10 o'clock to 4 o'clock). It is provided in a “upward (“) shape in front view.

  Therefore, even if the first vacuum drum 10 is rotating, a communication hole communicating with the fixed hood 11 (in the drawing, the communication from the 10 o'clock position to the 4 o'clock position on the clock face) .. Are only sucked in, and the original material 200 to be pasted overlapping at this portion is adsorbed from the vent hole. However, the suction force from the vent hole is set to a weak level that prevents the object 204 to be described later from dropping from the first vacuum drum 10.

  In addition, the first vacuum drum 10 is in contact with the second vacuum drum 30 (in the drawing, at the 3 o'clock position on the clock face) (hereinafter referred to as “transfer position”) P through the air vent. To be blown out. Therefore, the first vacuum drum 10 is provided with air supply means (not shown) for blowing air into the communication hole at the transfer position P on both side surfaces.

  Then, the position where the peeling means 50 for peeling the release separator 203 of the original article 200 to be peeled from the adhesive layer 202 starts to wind around the upstream side of the first die roll 20, for example, the first vacuum drum 10 (in the drawing). (Position at 9 o'clock on the dial of the watch) is arranged so as to be in contact with the original material 200 to be pasted. The peeling means 50 is composed of a knife edge, and is peeled off from the adhesive layer 202 when the release separator 203 is pulled back in the direction opposite to the traveling direction of the material to be stuck 200.

  Then, the first die roll 20 cuts the release separator 203 and cuts the material to be adhered 200 that overlaps the side surface of the first vacuum drum 10, that is, the adhesive layer 202 and the support 201. Forming the articles 204 to be individually connected in series, ladder-shaped blades (not shown) are projected around the periphery. Note that both sides of the object to be pasted 204 are discarded as scrap 205.

  The first die roll 20 is attached to the position adjusting means 21 so that the state in which the blade cuts the adhesive layer 202 and the support 201 can be finely adjusted.

  The second die roll 40 is for inserting a longitudinal split 301 into the product separator raw fabric 300 sandwiched between the second vacuum drums 30 and has a blade ( (Not shown) is projected. When inserting two back splits 301, two blades are naturally projected, and when inserting a corrugated spine 301, the blades are naturally projected in a corrugated form.

  In any case, the blade of the second die roll 40 rotates in the opposite direction to the second vacuum drum 30 while contacting the outer peripheral surface of the second vacuum drum 30, so that the product separator original fabric 300 is completely removed. It is cut and the spine 301 is inserted.

  The second die roll 40 is also attached to the position adjusting means 41 so that the state in which the blade puts the spine 301 into the product separator can be finely adjusted.

  The second vacuum drum 30 has a product separator blank 300 partially wound (in the drawing, from 4 o'clock to 12 o'clock on the dial of the watch), and in the opposite direction to the first vacuum drum 10 (drawing). In the clockwise direction) and slightly faster than the first vacuum drum 10.

  In addition, the second vacuum drum 30 is provided with a spine 301 so that the product separator blank 300 with the spine 301 inserted by the second die roll 40 is maintained while being wound around the second vacuum drum 30. It is designed to adsorb the product separator that has been put in.

  Therefore, as with the first vacuum drum 10, the second vacuum drum 30 is also formed with a large number of vent holes (not shown) on the side surfaces and connected to suction means (not shown) for evacuating both end surfaces. The hood 31 is fixed, and a plurality of communication holes 32, 32,... For communicating the vent hole and the hood 31 are provided therein. However, the hood 31 adsorbs only a part of the product separator web 300 that overlaps the side surface of the second vacuum drum 30 (in the drawing, from the 6 o'clock position to the 12 o'clock position on the clock face). It is provided in a “(” shape when viewed from the front.

  Therefore, even if the second vacuum drum 30 is rotating, the second vacuum drum 30 communicates with the fixed hood 31 (in the drawing, the communication from the 6 o'clock position to the 12 o'clock position on the clock face). Only the air holes 32, 32,... Are sucked, and the product separator original fabric 300 overlapping at this portion is adsorbed from the air holes.

  Further, as shown in FIG. 1, a cutting means 60 for cutting the product separator original fabric 300 into a predetermined shape is disposed on the downstream side of the second vacuum drum 30.

  The manufacturing apparatus of the adhesive covering body in this embodiment is comprised as mentioned above, and demonstrates operation | movement next.

  The material to be pasted 200 is fed from the roll and partially wound around the first vacuum drum 10. The original material 200 is peeled off from the adhesive layer 202 by the peeling means 50, the support 201 is overlapped with the first vacuum drum 10, and the first adhesive drum 202 is exposed outward. It advances following the rotation of the vacuum drum 10.

  Then, the first die roll 20 forms a cut in the adhesive layer 202 and the support 201, thereby forming the articles 204 to be bonded in series. Since the blade for putting the spine 301 is not applied to the product separator original 300 at the site where the spine can be put, the object 204 is not damaged. And since this to-be-adhered thing 204 is adsorb | sucked by the 1st vacuum drum 10, it advances without falling. Note that the adhesive layer 202 and the support 201 on both sides of the object to be pasted 204 become scrap 205 and are wound around a waste roll.

  On the other hand, the product separator blank 300 is unwound from the roll, and the second die roll 40 puts the spine 301 into a state. The product separator blank 300 with the spine 301 is adsorbed by the second vacuum drum 30 and advances following the rotation of the second vacuum drum 30.

  Then, at the transfer position P where the first vacuum drum 10 and the second vacuum drum 30 are in contact with each other, the object 204 is transferred from the first vacuum drum 10 to the product separator original 300 which is split back 301. To do. At the transfer position P, in the first vacuum drum 10, air is blown out from the air holes, so that the article 204 is pressed against the product separator original 300. Moreover, since the adhesive layer 202 having adhesiveness faces outward and is pressed against the product separator original 300, the object 204 is reliably transferred to the product separator original 300. It will be in the state of being affixed.

  Since the second vacuum drum 30 rotates slightly faster than the first vacuum drum 10, the adherend 204 is pulled by the product separator original 300, and the product separator original 300 is brought into contact with the product separator original 300. Transfer. Therefore, as shown in FIG. 3, the objects to be adhered 204 adjacent to each other on the first vacuum drum 10 are affixed to the product separator original fabric 300 with a space therebetween.

  And the product separator which stuck the to-be-attached thing 204 to which damage was not given leaves | separates from the 2nd vacuum drum 30, and is conveyed downstream. Then, the cutting means 60 cuts the product separator original fabric 300 in the width direction between the adherend 204 and the adherend 204, or cuts the product separator original 300 so as to surround the adherend 204. Thus, an adhesive covering is completed. This adhesive covering is conveyed further downstream, and is packaged in a packaging material by packaging means (not shown), thereby completing the final product.

  Note that the present invention can be variously modified without being limited to the above embodiment. For example, in the case where the material to be stuck 200 is not laminated with the release separator 203, the peeling unit 50 is not necessarily provided.

  Further, in order to rotate the second vacuum drum 30 slightly faster than the first vacuum drum 10, a motor rotating at the same speed is used, and the outer diameter of the second vacuum drum 30 is set to the first vacuum drum 30. The outer diameter of the vacuum drum 10 may be larger, or the first vacuum drum 10 and the second vacuum drum 30 may have the same outer diameter, and a motor for rotating the second vacuum drum 30 may be used. One vacuum drum 10 may be rotated faster than a motor that rotates the vacuum drum 10.

  Moreover, although it is preferable that the 1st vacuum drum 10 is provided with the spraying opening, it does not necessarily need to be provided.

  Moreover, although the apparatus which concerns on this invention can manufacture suitably the adhesive covering body for medical treatment, it can also manufacture the adhesive covering body of daily goods, such as a sticker, and industrial goods.
