Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a double-sided adhesive tape, a method of using the double-sided adhesive tape, and an apparatus for attaching an article using the double-sided adhesive tape.

[Conventional technology]

Conventional double-sided adhesive tapes have a structure in which a continuous piece of double-sided adhesive material is sandwiched between a backing paper and a release paper, which are also continuous.

To use such double-sided adhesive tape, cut the double-sided adhesive tape to the desired length, peel off the release paper and apply it to the desired location, then peel off the backing paper to expose the adhesive material piece. I try to paste certain things from above.

[Problem to be solved by the invention]

However, with the conventional double-sided adhesive tape mentioned above,
When using the tape, there is the inconvenience of having to prepare a cutter or the like to cut the tape to the required length.

In addition, when applying tape to a predetermined part that moves intermittently while being supplied by a machine, it is difficult to cut the tape while positioning the tape. If this is done, there is a problem that unnecessary parts will be created on the tape.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention has provided a continuous support sheet that is releasable to the adhesive material, and intermittently includes pieces of double-sided adhesive material in a shape suitable for the purpose of use along the longitudinal direction of the support sheet. The double-sided adhesive tape has a continuous release sheet attached on top of the tape.

In addition, as a method of using the double-sided adhesive tape, while feeding the double-sided adhesive tape, the release sheet is peeled off and removed.Then, the adhesive is pasted on the double-sided adhesive material piece on the support sheet, and then, the adhesive is moved in the direction of movement of the adhesive. The present invention employs means for peeling and removing the adhered object, including the double-sided adhesive material pieces, from the support sheet by making the running direction of the support sheet different from the running direction of the support sheet.

Further, as a pasting device for a pasted product using double-sided adhesive tape, there is provided a double-sided adhesive tape feeding section, a release sheet winding section for peeling and removing a release sheet from the double-sided adhesive tape fed out from the feeding section, and the double-sided adhesive tape. A winding unit is installed at a predetermined location to wind up the supporting sheet while intermittently running the supporting sheet, and a supporting sheet reversing unit for reversing the running direction of the supporting sheet is located in the running path of the supporting sheet from which the release sheet has been removed. A member is installed, and an adhesive is supplied to the double-sided adhesive material piece on the support sheet on the running path of the support sheet between the location where the release sheet is removed and the support sheet reversing member. An adhesive material supply unit is installed between the support sheet reversing member and the location where the adhesive material is to be pasted, and a double-sided adhesive is supplied from the support sheet at the location of the support sheet reversing member. A configuration is adopted in which a rotating transfer section is installed that holds the adhered object removed together with the piece of material and transports it to the above-mentioned attachment point.

[Effect]

When the continuous release sheet is peeled off from the double-sided adhesive piece,
Pieces of the double-sided adhesive material remained on the support sheet intermittently. Therefore, without cutting the tape or the like, the double-sided adhesive piece can be attached to a predetermined location by simply pressing the double-sided adhesive piece onto the object to be attached using the support sheet.

Further, when the tape is applied to a predetermined part or the like that is intermittently running while being supplied by a machine or the like, the double-sided adhesive material piece is affixed to the part or the like while being carried by the support sheet.

〔Effect of the invention〕

As described above, the double-sided adhesive tape according to the present invention has pieces of double-sided adhesive material intermittently pasted along the longitudinal direction of the support sheet on a continuous support sheet that is releasable to the adhesive material. Furthermore, since a continuous release sheet with better releasability than the supporting sheet is attached thereon, by peeling off the continuous release sheet from the double-sided adhesive material piece, the screen adhesive material piece can be removed. can be left on the support sheet and positioned intermittently on the support sheet. Therefore, without cutting the tape or the like, the double-sided adhesive piece can be attached to a predetermined location simply by pressing the screen adhesive piece onto the object to be attached using the support sheet, thereby simplifying and speeding up the adhesion work.

In addition, when applying double-sided adhesive tape to predetermined parts running along an assembly line, etc., the pieces of double-sided adhesive are intermittently placed on a continuous support sheet, so they cannot be used by machines, etc. This makes it possible to improve the efficiency of assembly operations, etc. Furthermore, since the pieces of double-sided adhesive material are arranged intermittently, there is no waste of adhesive material.

According to the method for using the double-sided adhesive tape, a piece of double-sided adhesive material is pasted on a piece of double-sided adhesive material on a support sheet after peeling and removing a release sheet, and then the moving direction of the said piece and the running of the support sheet are determined. By making the directions different from each other, the object to be adhered can be automatically peeled off and removed from the support sheet together with the double-sided adhesive material piece. Therefore, the operation of attaching the guide plate etc. can be accomplished easily and quickly.

According to the device for pasting things using double-sided adhesive tape, since the double-sided adhesive material piece on the support sheet and the thing to be pasted are peeled off and removed by the support sheet reversing member, the structure can be simplified accordingly. It is. In addition, since the attachment (military supply section) is installed on the running path of the support sheet between the location where the release sheet is removed and the support sheet reversing member, the attachment can only be placed on the double-sided adhesive piece. Therefore, the structure of the adhesive material supplying device can be simplified. Further, between the support sheet reversing member and the place to be pasted to which the pasted object is to be pasted, the adhered object that has been removed from the support sheet 1 along with the double-sided adhesive material piece is held at the location of the support sheet reversal member. Since a rotating transfer section is installed to transport the object to the place where it is to be applied, if the area to be applied is above the part, the double-sided adhesive is applied from a direction different from the direction in which the part is being transported. The object can be attached while supplying the tape. Therefore, it has the effect of being easy to incorporate into an assembly line or the like.
