Description

  The present invention relates to a laminator for adhering a laminate film to the surface of a medium, and more particularly to a laminator capable of removing foreign matter adhering to the surface of a medium before adhering the laminate film. .

  When sticking a laminate film to the surface of a medium on which characters or photos are printed, if foreign matter such as dust or dirt adheres to the surface of the medium, the aesthetics of the medium after the laminate film is attached will be impaired. become. For this reason, it is necessary to remove foreign matters such as dust and dirt adhering to the surface of the media. Generally, an operator removes foreign matters such as dust and dirt attached to the surface of a medium by holding a removal tool such as an antistatic brush or wipe in his / her hand.

  Although this technique is not a technique for removing foreign substances adhering to the surface of a medium in a laminator, a technique for removing foreign substances on a substrate is disclosed as a similar technique (see Patent Document 1). Also, in a gravure rotary press or dry laminator, a technique for removing deposits adhering to the sub-roller (see Patent Document 2), a technique for removing dust adhering to the clamping surface of the hot plate during the control operation of the laminator (patent) Reference 3) is disclosed.

  The technique described in Patent Document 1 performs a process of removing foreign matter in a vacuum using a foreign matter removing brush roll that is in contact with the base material and a foreign matter embedded brush roll that is interlocked while being in contact with the foreign matter removing brush roll. Thus, it is possible to prevent adhesion of an adhesive by the adhesive roll and to prevent the foreign matter attached to the foreign matter removing brush roll from reattaching to the substrate.

  The technique disclosed in Patent Document 2 is a roller device that sandwiches a belt-like sheet body between a main roller and a sub-roller and processes and conveys the belt-like sheet body, and is attached to the surface of the sub-roller in contact with the sub-roller. An adhesive roller for removing the kimono with adhesive force is provided. The sub roller has at least an outer peripheral portion formed of rubber, and the adhesive roller has at least an outer peripheral portion formed of an adhesive resin having adhesiveness.

  In conventional technology, when laminating a laminate film on the surface of the media, an operator holds a removal tool such as an antistatic brush or wipe in his hand and removes foreign matter such as dust or dirt attached to the surface of the media. In some cases, foreign matter may be left behind.

  Further, a method in which an operator presses an adhesive roller against the surface of a medium passing through a laminator transport path to remove foreign matters such as dust and dirt can be considered. In such a method, the operator presses the adhesive roller against the surface of the media passing through the laminator conveyance path to remove foreign matters such as dust and dirt, but at this time, since the adhesive roller is handheld, It is difficult to maintain an appropriate pressing pressure against the media surface, and it is also difficult to press the adhesive roller uniformly against the entire surface of the media. For this reason, the pressing operation of the adhesive roller requires skill, and there has been a difference in the quality of the laminated product according to the skill of the operator.

  The technique described in the above-mentioned prior art document uses an adhesive roller in an apparatus such as a laminator to remove foreign matters such as dust and dirt, but the surface of the media prior to laminating the laminate film is used. This does not remove the foreign matter by directly pressing the adhesive roller. Therefore, even if these prior arts are used, it is not possible to remove foreign matters such as dust and dirt adhering to the surface of the media before the laminate film is attached.

  Also, in an environment with low humidity such as in winter, static electricity may be generated, causing dust and debris to stick to the surface of the media, and dust and debris floating in the air to be attracted to the surface of the media. These foreign substances may not be completely removed. As described above, when the medium is charged with static electricity, it is difficult to completely remove foreign matters such as dust and dirt, and thus it is necessary to take measures against static electricity.

  The present invention has been proposed in view of the above-described circumstances, and can easily and reliably remove foreign matters such as dust and dirt attached to the surface of the media passing through the transport path of the laminator, thereby improving the quality of the laminated product. An object of the present invention is to provide a laminator that can be improved.

That is, the laminator according to the present invention is a device for sticking a laminate film to the surface of the media, and the adhesive surface is in pressure contact with the entire area of the surface of the media passing through the transport path with a uniform pressure. The pressure-sensitive adhesive roller is provided with an adhesive roller.

  In the laminator described above, the adhesive roller is preferably detachable from the laminator body.

  The laminator described above preferably includes an attachment position adjustment mechanism for adjusting the attachment position of the adhesive roller.

  Moreover, in the laminator described above, it is preferable that the adhesive portion of the adhesive roller has conductivity. In order to make the adhesive part having conductivity, for example, a conductive agent may be included in the adhesive part.

  According to the laminator according to the present invention, the adhesive roller is disposed in a state where the adhesive surface is pressed with a uniform pressure to the entire area of the surface of the medium passing through the conveyance path. Therefore, it is possible to easily and reliably remove foreign matters such as dust and dirt adhering to the surface of the media, and to improve the quality of the laminated product.

  In addition, by adopting a configuration in which the adhesive roller can be attached to and detached from the laminator body, it is possible to easily attach the media to the laminator body, so that work efficiency can be improved. Furthermore, since the adhesive roller can be easily cleaned and replaced, the quality of the laminated product can be improved in this respect as well.

  In addition, by adopting a configuration equipped with an attachment position adjustment mechanism for adjusting the attachment position of the adhesive roller, the adhesive roller can be attached to the optimum position according to the properties of the media and the laminate film. , Can improve the quality of laminate products.

  In addition, since the adhesive part of the adhesive roller has a conductive structure, static electricity charged on the medium can be guided to the outside of the laminator to eliminate the charged state, so that foreign matters such as dust and dirt can be reliably removed. it can.
