Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is directed to a pressure-sensitive adhesive for a winding tape, which is formed by winding a double-sided pressure-sensitive adhesive transfer tape coated with a pressure-sensitive adhesive on one side of a double-sided release paper. The present invention relates to an improvement in the structure of an automatic transfer device for a double-sided adhesive transfer tape that can be easily and reliably transferred to the position.

[Prior Art] This type of double-sided adhesive transfer tape is different from the conventional double-sided adhesive tape in that it can be adhered only by an adhesive without a core material, so that ideal adhesion based on the characteristics of the adhesive alone can be realized recently. It has become widely used.

An example thereof will be described below with reference to the drawings.

That is, in FIG. 6, 101 is a transfer device, and this transfer device 1
01 is a double-sided release paper 10 on the winding tape mounting shaft 103 of the casing 102.
A wrapping tape 106 formed by winding a double-sided adhesive transfer tape having a pressure-sensitive adhesive 105 applied on one surface 104a of 4 is rotatably loaded, and a spring-like pressure contact plate 107 is further provided inside the casing 102. The winding tape 106 is mounted in a direction opposite to the rotation direction of the winding tape 106, and a braking pressure is applied to the extent that the free rotation of the winding tape 106 is prevented. In the figure, reference numeral 108 is a tape exposing portion, and 109 is a delivery port of the double-sided release paper 104 on which the adhesive 105 has been peeled and transferred.

The automatic transfer device for a double-sided adhesive transfer tape having the above-mentioned structure has a space in the rotating direction of the winding tape inside the casing, especially in the vicinity of the lower side of the outlet for the double-sided release paper. There are no problems such as the accumulation of release paper, and as long as the user reliably presses the tape surface against the transfer object with uniform force and runs, there are no problems. When running with tilting, the adhesive will remain on the double-sided release paper,
It hindered smooth contact rotation with the pressure contact plate and hindered the release of the release paper from the delivery port, so it was necessary to get used to it without problems. Furthermore, since the mounting direction of the pressure contact plate is opposite to the rotation direction of the double-sided release paper, the drag force received during the rotation of the winding tape is relatively large, and not only when the residual adhesive on the double-sided release paper adheres, the tape Of the tape tends to become loose, and the slack that occurs in the tape due to the looseness has the effect of further hindering rotation at the pressure contact portion with the pressure contact plate that opposes the rotation direction of the winding tape,
There is also a possibility that the adhesive cannot be transferred smoothly in a constant state. Further, it is extremely difficult to directly transfer the casing to the surface to be transferred and transfer it, and when the casing is run with an inclination, the adhesive is not transferred to the surface to be transferred in an orderly manner and the desired adhesive effect cannot be obtained.

Further, the double-sided adhesive transfer tape itself used in an automatic transfer device for this type of double-sided adhesive transfer tape has the following problems.

2. Description of the Related Art In recent years, a double-sided adhesive transfer tape has been widely used in which a double-sided release paper is coated with a film of an adhesive and is wound into a tape. Compared with the conventional double-sided adhesive transfer tape using a core material, this kind of double-sided adhesive transfer tape is a simple and ideal tape, but the following unsolved problems remain.

That is, since the film-shaped adhesive is applied to the entire upper surface and the entire surface of the double-sided release paper, the adhesive sticks out to both sides when it is wound into a tape, and for example, this winding tape is stored in the case of the automatic transfer device. When it is used as an adhesive, the adhesive that sticks out inside the case sticks, and it hinders the smooth rotation of the double-sided adhesive transfer tape.
The pressure-sensitive double-sided adhesive transfer tape in which the adhesive portion is peeled off in the case and the adhesive is partially removed is also pressure-sensitively transferred. In order to solve such a defect, a plurality of pressure-sensitive adhesive pieces made of an adhesive film, etc. are formed on a double-sided release paper in a continuous manner with a slight gap in the longitudinal direction. Some of the papers are exposed. According to this improvement plan, when the double-sided adhesive transfer tape is incorporated as a winding tape in an automatic transfer device for a double-sided adhesive transfer tape and the double-sided adhesive transfer tape is directly used as a pressure-sensitive roller, the transfer device can be pulled up at a required end portion. Since the adhesive is not applied to the required space between the parts, it is possible to easily perform the transfer and adhesion work of the double-sided adhesive transfer tape with the required width without causing the situation that it can not be cut even if it is pressed hard and then pulled up as in the past. At the same time, the pressure-sensitive adhesive is transferred and adhered to the required end portion in an orderly manner, and there is no possibility that it will become liquid or have a thick or thin portion due to the pressing and cutting work as in the conventional case.

However, even in this type, since the adhesive is applied to the upper and lower parts of the adhesive piece, the adhesive sticks out from the side when incorporated into the automatic transfer device in the form of a winding tape, There remains a drawback that there is a possibility that the adhesive may adhere to the inside of the automatic transfer device and smooth rotation may not be possible.

[Problems to be Solved by the Invention] The present invention not only improves the double-sided pressure-sensitive adhesive transfer tape itself, but also responds accordingly to various types of automatic transfer devices for double-sided pressure-sensitive adhesive transfer tape using the double-sided pressure-sensitive adhesive transfer tape. By devising the device, the double-sided release paper to which the adhesive has been transferred can be guided and discharged extremely smoothly toward the outlet to completely prevent the double-sided release paper from accumulating inside the casing and prevent the double-sided release paper from having adhesive. Even if it remains, the double-sided release paper will be ejected without any trouble, and since the wrapping tape has good rotatability and the directionality is also good at the time of transfer work, it runs with the tape surface inclined and the adhesive is neatly placed at a predetermined place. The transfer of release paper and the transfer of adhesive to the required surface can be performed reliably and smoothly without the risk of not being transferred, and it requires skill even if used by an inexperienced user. It is intended to provide an automatic transfer device for a double-sided adhesive transfer tape, which can perform a suitable transfer operation without any need and is devised for storage when not in use.

[Means for Solving the Problem] The above-mentioned problem is that a double-sided release paper is coated with a pressure-sensitive adhesive on one side, and a double-sided pressure-sensitive adhesive transfer tape is wound so that the pressure-sensitive adhesive is exposed on the outer surface. A spring-like pressure contact plate that is inserted into the casing and presses against the winding tape to prevent free rotation of the winding tape is attached inside the casing, and the adhesive surface of the winding tape is exposed below the casing. A double-sided adhesive transfer tape has an automatic transfer device structure in which a cutout portion is provided in order to provide a double-sided release paper on which the adhesive has been peeled and transferred and which is ejected above the casing. The adhesive to be applied has a double-sided release paper exposed portion formed on the upper side and the lower side in order to form a dry edge portion on the upper side and the lower side in the longitudinal direction of the double-sided release paper. Above the casing On the winding tape rotation direction side of the inside of the delivery port, the dry edge of the double-sided release paper on the surface of the winding tape freely moves down in the direction of the winding tape due to its own weight in the groove-shaped or bag-hole-shaped guide portion. A free contact piece, which has a notch for abutting only a portion and is made of a relatively heavy material such as an iron material, is positioned as a stopper for preventing release paper entrapment, and the spring-like pressure contact plate is provided inside the casing. While protruding from the peripheral mounting base in the direction learned in the direction of rotation of the winding tape, the end of this pressure contact plate is pressed against only the dry edge portion of the double-sided release paper and remains on the double-sided release paper after transfer to the contact part. It has a notch to avoid contact with the adhesive, and both ends of the pressure contact plate are always in positive contact with only the dry edge part, and pressure contact is performed to prevent both ends of the pressure contact plate from moving laterally. Both ends of board Of at somewhat as the rear is solved by a double-sided pressure-sensitive adhesive transfer tape of the automatic transfer device, characterized in that projecting from the guide plate toward the winding tape direction.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 to 5, reference numeral 1 is a transfer device, and the transfer device 1 is shown in FIGS. 1, 2 and 3 on a winding tape mounting shaft 3 of a casing 2 having a lid portion 2a. Double sided release paper 4
The pressure-sensitive adhesive piece 5 is made narrower on one side 4a than the double-sided release paper 4 so as to form a dry edge portion 4b where no adhesive is present in the longitudinal direction, the upper side and the lower side of the double-sided release paper 4,
A winding tape 6 formed by winding a double-sided adhesive transfer tape which is continuously applied at a small interval is rotatably loaded. Further, as shown in FIG. 1, FIG. 2, and FIG. 4, only the dry edge portion 4b of the double-sided release paper 4 is brought into contact with the inside of the casing 2 to prevent the winding tape 6 from freely rotating. Therefore, a spring-like pressure contact plate 7 having a notch 7b for avoiding contact of the adhesive 5 remaining on the double-sided release paper is attached to the contact portion 7a in a direction learned in the rotation direction of the winding tape 6, and peeling is performed. The braking pressure is applied to the extent that the paper feeding direction is regulated and free rotation of the winding tape 6 is prevented. Further, according to the present invention, both ends of the abutting portion 7a of the pressure contact plate 7 are positioned slightly rearward so that the both ends of the abutting portion 7a of the pressure end plate 7 are always reliably in contact with only the dry edge portion 4b. Guide plates 7c are provided on both side edges so as to project in the winding tape direction so as not to slip or fall off. In FIG. 1 and FIG. 2, 8 is the tape exposing portion, 9 is the double-sided release paper 4 in the same manner as the pressure-contact plate 7 for discharging the double-sided release paper 4 on which the adhesive 5 has been peeled and transferred as shown in FIG. It is a double-sided release paper delivery port provided with a notch 9a for avoiding contact with residual adhesive on the side where the surface 4a on which the adhesive 5 has been applied comes into contact. Reference numeral 10 denotes a groove-shaped or bag-hole-shaped guide portion formed inside the winding tape rotation direction protruding portion 11 of the casing 2 with respect to the delivery port 9, and the guide portion 10 has the weight of the winding tape. A free contact piece 12 which is made of a relatively heavy material such as iron and has a notch 12a for avoiding contact with the adhesive 5 so as to allow free movement and descent in the same direction as the pressure contact plate 7 is housed. Is. Therefore, the release paper does not come into contact with the rotating pressure-sensitive adhesive piece and also serves as a stopper member, and there is no possibility that the release paper will be caught inside the casing as the winding tape rotates and stay.

Reference numeral 13 denotes a forefinger placement surface, which is a lower surface of the projection member 11 in the direction opposite to the anti-peeling paper feeding direction and a face body which is continuous with this and inclines upward toward the upper surface of the casing. Projections or protrusions 13a are formed.

Reference numeral 14 denotes projections or ridges for hooking fingers of the thumb and middle finger, which are formed on both sides of the casing in the transfer direction. If the casing is gripped by the index finger, thumb, and middle finger and the transfer operation is performed, the tape surface is formed. There is no fear that the tape surface will be surely opposed to the surface to be transferred, the tape surface will be inclined, and the adhesive will not be transferred in order to a predetermined position.

Reference numeral 15 is a through hole for locking formed in the casing when the double-sided adhesive transfer tape automatic transfer device is stored or not used.

[Advantage of the Invention] In the automatic transfer device structure of the double-sided adhesive transfer tape having the above-described structure, the width of the adhesive applied to the double-sided release paper of the winding tape is narrower than the width of the double-sided release paper in the tape itself. The double-sided release paper has dry edges on the upper and lower sides of the double-sided release paper in the absence of adhesive, and a groove or bag hole inside the protrusion on the winding tape rotation side from the delivery port inside the casing. Of the guide member is formed, and a free contact piece made of a relatively heavy material such as iron is positioned inside the guide part so that the weight of the guide part allows free movement and descent in the winding tape direction. Since the notch is formed so as to avoid the adhesive of the rotating winding tape and contact only the dry edge part, the adhesive has been peeled off and transferred when it can exert a smooth winding tape rotation effect. Double sided release paper Due to the stopper action and the guide action of the release contact paper entrainment in the casing of the free contact plate, the guide sheet is discharged very smoothly toward the delivery port. Further, a notch is provided at the contact portion of the spring-like pressure contact plate that suppresses the free rotation of the winding tape with the winding tape to avoid residual adhesive and press only the dry edge portion, and the dry edge portion of the pressure contact plate. At both ends of the abutting part, guide plates 7c are provided to the rear of the abutting plate so that both ends of the abutting plate are always in abutting contact only with the dry edge part and are prevented from falling off. Since both ends of the pressure contact plate fall off from the ends of the winding tape or are misaligned, both ends of the pressure end contact the adhesive that remains on the double-sided release paper that has finished the transfer, and smooth. Unforeseen circumstances such as the inability to send out release paper can be completely prevented. Similarly, by providing a notch on the side where the adhesive-coated surface of the double-sided release paper at the outlet for discharging used double-sided release paper contacts, the adhesive remains on the double-sided release paper. Even then, the double-sided release paper came to be discharged without any trouble.
Further, when the mounting direction of the spring-like pressure contact plate that suppresses the free rotation of the winding tape is attached in a direction that follows the rotation direction of the winding tape, almost no counterforce is generated against the forced rotation of the winding tape. Therefore, the winding of the tape is not loosened, that is, the rotation of the winding tape is very smooth, so that the transfer of the adhesive can be reliably performed in a stable state.
