  When the edge of the adherend 2 is coincident with the edge of the product separator 3, the adhesive cover body protrudes from the product separator 3. It is formed larger than 2. By providing a wide area (dry edge) 4 around the product separator 3 to which the object 2 is not attached, the appearance of the adhesive covering can be improved.

  And when the to-be-attached material original 102 for forming the to-be-attached material 2 is formed in the same width as the product peeling tape original material 103 for forming the product separator 3, wide dry edge 4 is used. In order to manufacture the provided adhesive covering, both sides of the material to be pasted 102 must be widely cut.

  However, in particular, if the object to be adhered 2 contains an expensive drug, it is not preferable to widely cut both sides of the material to be adhered 102 because it causes a large increase in the cost of the product. In addition, it is desirable to eliminate waste loss as much as possible even if expensive drugs are not included.

  Therefore, the present invention provides an apparatus for manufacturing an adhesive covering that can manufacture an adhesive covering provided with a wide dry edge without widely cutting both sides of an original material to be pasted. The issue is to provide.

The second article roll is placed so that the article to be stuck separated from the release separator is transferred by the means, and the second die roll that splits the product separator original wound around the second drum sandwiches the product separator original. It is characterized by having a vacuum function that is disposed adjacent to the drum, and that adsorbs the product separator original fabric from which the second drum is split .

  According to this apparatus for producing an adhesive covering, the object to be adhered is formed by making a cut in the support and adhesive layer of the material to be adhered, but the material to be adhered is wider than the product separator original. By being narrowed, the object to be attached is also narrower than the product separator original, and the width between the edge of the object to be transferred transferred to the product separator original and the edge of the product separator original is wide. A part (dry edge) is provided, and scrap removed from both sides of the material to be stuck can be minimized.

Then, when the second drum is disposed adjacent to the peeling means, the adherend from which the release separator has been separated by the peeling means advances toward the product separator original fabric partially wound around the second drum. Then, after the front end portion of the object to be pasted contacts the product separator original fabric, it is pasted while being pulled by the product separator original fabric which is separated from the second drum and proceeds in the same direction as the direction of conveyance of the original material to be adhered. As a result, the entire surface of the object to be pasted is transferred to the original product separator.
And since the product separator original fabric is split by the second die roll, a product separator with a split is formed, and an easy-to-use adhesive covering can be manufactured. And since the 2nd drum is provided with the vacuum function, even if a product separator original fabric is split back, it can be wound around the 2nd drum and can advance.

This apparatus for manufacturing an adhesive covering is for manufacturing an adhesive covering as shown in FIG. 5 from a material to be adhered 200 and a product separator original 300, and includes a first drum 10 and a first die roll. 20, a peeling means 30, a second drum 40, and a second die roll 50 are provided.

  The material to be adhered 200 is for forming the material 2 to be adhered, and is composed of three layers in which an adhesive layer 202 is laminated on the entire surface of one side of a belt-like support 201 and a release separator 203 is laminated on the adhesive layer 202. It is structured, is fed out from a roll (not shown), and is conveyed in the length direction and basically in the horizontal direction. Although the conveyance direction of the original article 200 is not limited to the horizontal direction as illustrated, it will be described here with reference to the drawings.

  Moreover, the product separator original fabric 300 is for forming the product separator 3 (see FIG. 5), is formed of flexible hard plastic, and is fed out from a roll (not shown). In addition, the to-be-bonded original fabric 200 is narrower than the product separator original fabric 300.

  And the 1st drum 10 and the 1st die roll 20 are arrange | positioned up and down so that the to-be-attached material original fabric 200 may be pinched | interposed, and it is an opposite direction so that the to-be-attached material original fabric 200 may advance intermittently to a length direction It is designed to rotate in the clockwise direction and counterclockwise direction in the drawing. Further, the first drum 10 comes into contact with the release separator 203 and presses the material to be pasted 200 against the first die roll 20.

  The first die roll 20 is provided with a ladder-shaped blade (not shown) continuous on the side surface (surrounding), and a cut 205 is made in the support 201 and the adhesive layer 202 of the material to be pasted 200. Thus, the quadrangular object 2 is formed. When the corner of the object 2 is arcuate, the edge of the blade is also arcuate, and when the object 2 is circular or oval, the blade is also circular or oval. It is done. In any case, scrap 204 is formed on both sides of the support 201 and the adhesive layer 202 into which the cut 205 is made. The scrap 204 is partially wound around the first die roll 20 and separated from the release separator 203 and removed.

  And the peeling means 30 is provided by the knife edge which sharpened the front-end | tip part 31, for example, and the angle | corner which the main surface 32 and the return surface 33 make is made into a sharp acute angle. The release separator 203 of the original material 200 is overlapped with the main surface 32 of the peeling means 30, and the tip 31 is directed in the traveling direction of the original material 200. Then, the release separator 203 is pulled back from the front end portion 31 of the peeling means 30 along the folding surface 33 in the direction opposite to the traveling direction, so that only the article 2 is continuously advanced from the front end portion 31 of the peeling means 30. ing.

  The second drum 40 and the second die roll 50 are arranged vertically so as to sandwich the product separator web 300, and are rotated in opposite directions (clockwise and counterclockwise in the drawing). Further, the second drum 40 is disposed in the vicinity of the peeling means 30. The illustrated peeling means 30 is disposed in an inclined posture so that the front end portion 31 faces the upper end of the second drum 40 (in the drawing, the 12 o'clock position on the clock face).

  Then, the product separator blank 300 is partially wound around the second drum 40 (in the drawing, from the 4 o'clock position to the 12 o'clock position on the clock face) and proceeds in one direction. In addition, the roller 60 which presses the product separator original fabric 300 against the second drum 40 is disposed so as to contact the second drum 40 via the product separator original fabric 300 (at the 4 o'clock position in the drawing).

  And the 2nd die roll 50 shall be provided with the blade (not shown) for putting the back split 301 in the product separator original fabric 300. As shown in FIG. When only one spine 301 is provided along the center line of the product separator web 300, only one blade is naturally provided. When multiple spine 301 is provided, naturally, a plurality of blades are provided. When the spine 301 is provided in the waveform, the blade is naturally provided in the waveform.

  Then, the second drum 40 is provided with a vacuum function so that the product separator original fabric 300 with the spine 301 inserted can advance while being partially wound.

  That is, the second drum 40 has a large number of vent holes (not shown) formed on the side surface, and a hood 41 connected to suction means (not shown) for evacuating the both end surfaces is fixed inside. A number of communication holes 42, 42,... Communicating the vent hole and the hood 41 are provided. However, the hood 41 has a front surface so as to suck the divided product separator blank 300 that overlaps the side surface of the first drum 40 (in the drawing, from the 6 o'clock position to the 12 o'clock position). The visual “(” character is provided.

  Therefore, even if this 2nd drum 40 is rotating, it is a communicating hole (it is a communicating hole from the 6 o'clock position to the 12 o'clock position on the dial of the clock in the drawing). ) 42, 42,... Are sucked in, and the product separator original fabric 300 overlapping at this portion is adsorbed from the vent hole. That is, since the communication hole is configured not to suck air at a portion where the product separator original fabric 300 is not stacked, the product separator original fabric 300 is adsorbed to the second drum 40 with a necessary suction force.

  Further, a cutting means (not shown) for cutting the product separator original fabric 300 into a predetermined shape is disposed on the downstream side of the second drum 40.

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

  The original material 200 to be stuck is fed from a roll and intermittently conveyed in the length direction while being sandwiched between the first drum 10 and the first die roll 20. Then, the cuts 205 are made in the support 201 and the adhesive layer 202 of the workpiece original fabric 200 by the blades of the first die roll 20, and the workpiece 2 is continuously formed one after another, and the scrap 204 is formed on both sides. Is done.

  The scrap 204 is partially wound around the first die roll 20 and separated from the release separator 203 and removed. On the other hand, the release separator 203 and the adherend 2 advance intermittently toward the peeling means 30. And in the peeling means 30, when the release separator 203 is pulled back along the folding surface 33, only the to-be-sticked object 2 advances intermittently toward the 2nd drum.

  On the other hand, the product separator web 300 is unwound from the roll and continuously conveyed in the length direction while being sandwiched between the second drum 40 and the second die roll 50. Then, the second die roll 50 puts the spine 301 into the product separator blank 300 and divides it into two. However, since the second drum 40 has a vacuum function, the product separator original fabric 300 divided into two parts is continuously advanced while adsorbing.

  Then, as shown in FIG. 2 (a), the second product separator original fabric that is being advanced by the second drum 40 is formed such that the tip 2a of the object 2 to be pasted that has progressed intermittently hangs down. When contacting 300, the progress of the material to be pasted 200 stops. However, since the tip 2a is stuck and pulled on the second product separator raw fabric 300 that is progressing, the article 2 to be pasted is pulled up to the rear end 2b as shown in FIG. 2B. Affixed to anti-300. In this way, the object 2 is completely transferred to the product separator web 300.

  After the article 2 is completely transferred to the product separator original 300, the article original 200 is stopped for a while and then proceeds. By doing so, the next object to be adhered 2 is transferred to the product separator original fabric 300 that moves away from the second drum 40 with a space between the object 2 to be adhered.

  In this way, a large number of objects to be stuck 2 are transferred one after another to the product separator original 300 at intervals. Then, on the downstream side (right side in the drawing), the product separator original fabric 300 is cut by the cutting means between the adhering object 2 and the adhering object 2 adjacent to each other, as shown in FIG. A sticky coated body in which a dry edge 4 is provided on a product separator 3 and the object 2 is adhered is completed.

  In this adhesive covering, the adherend 2 is continuously formed one after another from the adherend original 200 having a width narrower than that of the product separator original 300, and the interval between the adherend 2 and the adherend 2 is formed. And the product separator original fabric 300 is cut between the object 2 and the object 2 to form the product separator 3. A wide dry edge 4 is provided between the edge and the edge of the product separator 3.

Note that the present invention can be variously modified without being limited to the above embodiment .

For example , the apparatus for producing an adhesive covering does not cause the workpiece original fabric 200 to move intermittently, but continuously advances the product separator substrate 300 faster than the workpiece original fabric 200. Accordingly, a wide interval may be provided between the object 2 to be adhered and the object 2 to be adhered to the product separator original fabric 300.

  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.
