The present invention relates to a tab forming tape cutter to be formed.

  Conventionally, manual tape cutters used for cutting adhesive tapes have been used in a wide range of fields, and tape cutters have become established as indispensable equipment from daily life to business use. At present, many techniques for improving the function of the tape cutter and improving the usability have been developed.For example, the adhesive surfaces of the residual tape after cutting the tape are bonded to each other like the tape cutter according to the present invention. Various techniques have been developed for bonding and forming tabs. The applicant of this case is a developer of a tape cutter disclosed in JP-A-2005-75560, JP-A-2006-103808, JP-A-2012-101932, etc., and has other functions and conveniences. Engaged in research and development of enhanced tape cutters.

  Many of the uses of the adhesive tape are used for the purpose of bonding two or more objects or edges of one sheet of paper. For example, it is used when a product is packed and fixed with a wrapping paper in a supermarket or a department store for business use, or when an envelope or the like is closed. On the other hand, the purpose may be to peel off the tape from the beginning. For example, in order to prevent parts such as electrical products from floating in the packaging, it is generally performed to temporarily fasten each part with an adhesive tape, and the adhered tape is required to be easily peeled off. Yes.

  In such a purpose of use, depending on the degree of adhesion of the adhesive tape, the adhesive tape is strongly adhered to the object and difficult to peel off. As an improvement measure, the end of the adhesive tape is folded to the adhesive tape side, A device has been devised in which the surfaces are bonded to each other so that a tab that becomes a non-sticking knob is formed at the tip, and this part can be easily picked and peeled off.

  As a technique relating to a tape cutter for forming a tab serving as a knob provided at the end of such an adhesive tape, there is a technique disclosed in JP-A-11-49419. In the present invention, when forming a tab at the tip of the cut tape, the tape cutter includes a cutter mechanism for cutting the adhesive tape, a folding mechanism for folding the tip surface of the residual tape, and a folding process for the folded portion. Each of the mechanisms has a folding mechanism, and the cams provided in each mechanism may cause a shift in the linkage operation of the adhesive tape cutting process, the remaining tape tip folding process, and the folding part folding process. A technique for forming a tab at the tip of an adhesive tape to be pulled out in preparation for the next cutting is disclosed.

It was. In addition, since the accuracy of the equipment is required, there is a problem that the production cost of the tape cutter is high.

  Japanese Patent Application Laid-Open No. 9-30718 discloses a pressure-sensitive adhesive tape in which the front end portion of the pressure-sensitive adhesive tape is engaged with the adhesive surface of the swinging arm as a tape cutter that automatically forms a knob on the front end of the pressure-sensitive adhesive tape. The swing arm is swung away from the standby section by pulling out the tip of the arm, and then the adhesive tape is adhered to the standby section. After the adhesive tape is cut, the standby arm is engaged with the adhesive tape. A technique for forming a knob on an adhesive tape by returning to a position adjacent to the tape is disclosed.

  However, according to the disclosed technique, the adhesive tape is bent backward (lower side), and the situation where the formation of the knob is failed has occurred. No particular disclosure or suggestion has been made regarding a method for accurately forming the knob part upward, and the tab forming tape cutter for forming the knob part has a drawback in this respect. In addition, adhesive tapes of various widths exist, and it is particularly difficult to form tabs for narrow adhesive tapes. In particular, in the present disclosure, it is sufficient to form tabs on narrow adhesive tapes. There was a problem that it was not possible.

  Japanese Patent Application Laid-Open No. 2004-284687 discloses a method in which an adhesive tape is cut in a state where the movable cutter portion is separated and rotated and temporarily attached to the temporary receiving portion, and the movable cutter portion is returned and rotated by a spring. A technique for forming a tab is disclosed. According to this technique, an inexpensive and highly durable tape cutter can be manufactured, but there is a problem that it is difficult to reliably form a tab in the upward direction. In addition, although it is difficult to form a tab of a narrow adhesive tape, this invention also has a problem that it cannot sufficiently cope with the narrow adhesive tape.

Therefore, it is desired to develop a tab-forming tape cutter that can form tabs accurately as tabs without making the structure too complicated, and can easily form tabs even with a narrow adhesive tape. It was.

  The pressure-sensitive adhesive tape 20 is rotatably held by the tape mounting portion 30 in a wound state, and the pull-out operation places the pressure-sensitive adhesive surfaces at a certain length on the front end surface of the pressure-sensitive adhesive tape (the top of the remaining tape pulled out). It is pulled out to the tape cutting part 40 via a tab forming part 50 for forming a tab to be bonded to form a tab. Thereby, at the time of the next tape drawing and cutting, the adhesive tape 20 on which the tab is formed can be pulled and cut and used.

  The tape cutting unit 40 is a member that cuts the drawn adhesive tape 20, and includes a cutter 42 and a cutter holding unit 44, and the cutter holding unit 44 holds the cutter 42 fixedly as shown in FIG. The structure is fixed to the tape cutter body 10. In this embodiment, the cutter 42 of the tape cutting unit 40 is configured to be detachably attached to the cutter holding unit 44. Thereby, when the cutter 42 is deteriorated or another cutter 42 having a different blade shape is used, the cutter 42 can be easily replaced and used as another type of tape cutter.

  The tab forming unit 40 is used for a tape to be used next time by pulling out a tab to be used as a knob part by folding the tape back to the top portion of the adhesive tape 20 remaining after the cutting process and bonding the adhesive surfaces to each other with a certain length. As shown in FIG. 1, it is a member for forming, and is composed of a fixed adhesive holding portion 60 and a swinging portion 70 provided with a swinging adhesive holding portion 80.

Next, operation | movement of the rocking | swiveling part 70 at the time of forming a tab in the adhesive tape 20 is demonstrated.
When pulling out the pressure-sensitive adhesive tape 20, the pressure-sensitive adhesive tape 20 is once bonded to the swing bonding holding portion 80. Thereby, the swinging part 70 moves forward in the extending direction of the adhesive tape 20 (the direction of the tape cutting part 40) in a state where the swinging adhesive holding part 80 adheres and holds the adhesive tape 20. When the adhesive tape 20 is cut by the tape cutting unit 40, the swinging adhesive holding unit 80 moves backward toward the fixed adhesive holding unit 60 by an urging force in a state where the remaining top portion of the adhesive tape 20 is bonded and held. . At this time, as described above, since the drawn-out adhesive tape 20 is in a state of being fixed by the fixed adhesive holding portion 60 at the time of cutting, the leading portion of the remaining adhesive tape 20 is folded back to form a tab. Will be.

Hereinafter, the structure of the swing part 70 will be described.
As shown in FIGS. 2a to 2d, the swinging unit 70 includes a swinging base portion 72 made of a crank-shaped long piece, a first shaft body 74, a swing control piece 76, a second shaft body 78, It consists of the elastic body 100, draws a substantially elliptic arc, and performs forward movement toward the tape cutting part 40, which is the extending direction of the adhesive tape 20, and backward movement toward the fixed adhesive holding part 60.

  As shown in FIGS. 2a to 2d, the swing base 72 is formed of a crank-shaped long piece, provided with a swing adhesive holding portion 80 at the upper end, and a shaft hole 71 having a long hole extending in the longitudinal direction at the lower end. It is formed so as to swing back and forth about a long hole shaft hole 71. The first shaft body 74 is a shaft body that serves as a rotation shaft of the swing base 72, and is loosely fitted in a long shaft hole 71 formed in the swing base 72. As a result, as shown in FIG. 5, the swing base 72 can swing up and down while swinging back and forth.

  The swing control piece 76 is a member that controls swinging back and forth and up and down movement about the first shaft 74 by the swing base 72. As shown in FIGS. 2 a to 2 d, the swing base 72. Is rotatably connected to. Since the swing control piece 76 is a member shorter than the swing base 72, the rotation radius is also short. The second shaft body 78 is a rotation shaft of the swing control piece 76 and is rotatably installed with the swing control piece 76 connected to the swing base 72 with the second shaft body 78 as a central axis. The

  The elastic body 100 is a member that biases the swing base 72 toward the fixed adhesive holding portion 60. In this embodiment, as shown in FIGS. 2a to 2d, the swing base 72 is fixed using a spring. It is installed so as to be pulled toward the adhesive holding part 60. The elastic body 100 is not limited to the spring type as in this embodiment, and it is also possible to use a rubber member. Alternatively, the swing base 72 may be urged so as to be pushed from the tape cutting unit 40 side toward the fixed adhesive holding unit 60.

  As shown in FIG. 2 a, the swing base 72 is installed so as to swing and move up and down with the first shaft body 74 as a rotation axis, and is further connected to the swing base 72 so as to be rotatable. When the motion control piece 76 performs shaft rotation about the second shaft body 78, the swing operation of the swing base 72 is controlled.

  As shown in FIG. 2B, the swing base 72 urged toward the fixed adhesive holding portion 60 by the elastic body 100 is fixedly bonded as the adhesive tape 20 bonded to the swing adhesive holding portion 80 is pulled out. It separates from the holding part 60. At this time, the swing base 72 swings so as to draw an arc shape corresponding to the arc drawn by the shaft rotation movement of the swing control piece 76 while performing the shaft rotation movement with the first shaft body 74 as the rotation axis. That is, since the swing control piece 76 is shorter than the swing base 72, the swing base 72 rotates so as to protrude upward in response to the rotation of the swing control piece 76. Since the first shaft body 74 has a structure that is loosely fitted into a long shaft hole 71 formed in the swing base portion 72, the swing base portion 72 having the first shaft body 74 as a rotation shaft is stable. It can swing and move up and down.

After the adhesive tape 20 is pulled out to a desired length, in this embodiment, as shown in FIG. 2 c, the swinging adhesive holding unit 80 installed on the swinging base 72 responds to the rotation of the swinging control piece 76. As a result, the swinging base portion 72 is lowered to be positioned below the fixed adhesive holding portion 60. As a result, the adhesive tape 20 is securely bonded and held by the fixed adhesive holding portion 60.
Through the above series of operations, the swinging portion 70 draws a substantially elliptical arc as shown in FIG. 5 and moves forward toward the tape cutting portion 40, and similarly moves backward toward the fixed adhesive holding portion 60. Will be done.

  Next, when the adhesive tape 20 is cut, as shown in FIG. 2 d, the swing base 72 is automatically rotated toward the fixed adhesive holder 60 by the biasing force of the elastic body 100. At this time, the oscillating adhesive holding part 80 installed on the oscillating base 72 keeps the remaining adhesive tape 20 adhered and held, and at the same time, the remaining adhesive tape 20 is also adhered and fixed to the fixed adhesive holding part 60. Therefore, when the swinging adhesive holding portion 80 approaches the fixed adhesive holding portion 60 while drawing a substantially elliptical arc, a tab serving as a knob portion is formed on the remaining adhesive tape 20.

  Since the rocking body 70 performs the above-described operation, when the adhesive tape 20 is pulled out, the pressure-sensitive adhesive tape 20 is adhered and held to the rocking adhesive holding part 80 in a state where the adhesive tape 20 is not in contact with the fixed adhesive holding part 60. 20 can be pulled out, and the adhesive tape 20 can be securely bonded to the fixed adhesive holding portion 60 when the adhesive tape 20 is cut. Furthermore, after the adhesive tape 20 is cut, the rocking adhesive holding portion 80 that holds and holds the adhesive tape 20 approaches the fixed adhesive holding portion 60 while drawing a substantially elliptical arc, so that a reliable tab can be formed. Become. Further, when the swing base 72 swings, the swing adhesive holding part 80 moves back and forth in a substantially horizontal state, thereby preventing the adhesive tape 20 from peeling from the swing adhesive holding part 80. The effect can also be expected.

  As shown in FIG. 3, the swing adhesion holding portion 80 is provided with a tab formation auxiliary portion 90. The tab formation assisting portion 90 is a plate-like member for adhering and holding the adhesive tape 20 in a substantially concave shape, and includes a swinging bottom surface portion 92 and a swinging inclined portion 94. As shown in FIG. 3, the swinging bottom surface portion 92 is located at the center portion of the surface of the tab forming auxiliary portion 90 to which the adhesive tape 20 is bonded, and holds the central portion of the adhesive tape 20 by adhesion. Further, as shown in FIG. 3, the swing inclination portion 94 is located at the left and right end portions of the surface to which the adhesive tape 20 of the tab forming auxiliary portion 90 adheres, and is inclined upward from the swing bottom surface portion 92 toward both ends. It is a surface provided with an inclination angle to be inclined, and both ends of the adhesive tape 20 are inclined and bonded and held.

  As described above, the tab forming auxiliary portion 90 has a surface in which the adhesive tape 20 is bonded and held in a substantially concave shape, so that the adhesive tape 20 can be bonded and held in a substantially concave shape. As a result, after the adhesive tape 20 is cut, the swinging adhesive holding portion 80 swings toward the fixed adhesive holding portion 60 while bending the adhesive tape 20 upward, so that tabs can be easily formed on the adhesive tape 20. It becomes.

  Since the pressure-sensitive adhesive tape 20 is wound in a state of being stuck to its own non-adhesive surface, the pressure-sensitive adhesive tape 20 drawn out from the non-adhesive surface is usually warped with the non-adhesive surface inside. It becomes easy to become. For this reason, tab formation is performed with the adhesive surface protruding and warped, and particularly in the case of a narrow width (12 mm) tape, the conventional tab forming tape cutter is bent upward (the adhesive surface is inside and bent). It was difficult to form tabs accurately in the direction). By using the tab forming auxiliary part 90 having the above-described shape, the adhesive tape 20 is easily bent upward, and further, the swinging adhesive holding part 80 maintains a substantially elliptical arc while maintaining this state. The tabs can be formed accurately even with a narrow (12 mm) tape.

  Although the width of the swing bottom surface portion 92 is not particularly limited, in this embodiment, the width is set to be less than 12 mm in order to make it possible to form a tab of a narrow width (12 mm) tape. In addition, the inclination angle of the swing inclination portion 94 is not particularly limited, but in this embodiment, an inclination angle of about 30 degrees is used in order to reliably form a tab. In addition, if the width of the swinging bottom surface portion 92 is too narrow or the tilting angle of the swinging tilting portion 94 is too large, the adhesive tape 20 may be excessively bent and the cut surface of the cut adhesive tape 20 may not be linear. Therefore, it is desirable to provide an appropriate width and inclination angle.

  The fixed adhesive holding portion 60 can be configured to have a fixed bottom surface portion 62 and a fixed inclined portion 64 in order to bond and hold the adhesive tape 20 in a substantially concave shape. As shown in FIG. 4, the fixed bottom surface portion 62 is positioned at the central portion of the surface to which the adhesive tape 20 of the fixed adhesive holding portion 60 is bonded, and holds the central portion of the adhesive tape 20 by adhesion. The fixed inclined portion 64 is located on the left and right end portions of the surface to which the adhesive tape 20 of the fixed adhesive holding portion 60 adheres, and is a surface provided with an inclination angle that is inclined upward from the fixed bottom surface portion 62 toward both ends. Yes, both ends of the adhesive tape 20 are tilted and held.

  The fixed adhesive holding unit 60 can press and hold the adhesive tape 20 against the substantially concave shape by forming the adhesive holding surface of the adhesive tape 20 into a substantially concave shape with the center being concave as described above. It becomes possible. Thereby, since the adhesive tape 20 is easily bent upward, it is easy to form a tab on the adhesive tape 20.

  Note that the width of the fixed bottom surface portion 62 is not particularly limited, but in this embodiment, it is possible to form a tab of a narrow (12 mm) tape, so that it can be less than 12 mm. In addition, the inclination angle of the fixed inclination portion 64 is not particularly limited, but in this embodiment, the inclination angle is about 30 degrees in order to reliably form a tab. In addition, since the adhesive tape 20 may bend and an unnecessary crease may be attached to the adhesive tape 20 when the width of the fixed bottom surface portion 62 is excessively narrowed or the fixed inclined portion 64 is excessively inclined, an appropriate crease is considered. It is desirable that the width and the inclination angle be provided.

  As shown in FIG. 3, the tab formation assisting portion 90 can be configured to be detachable from the swinging adhesive holding portion 80. In this embodiment, the fixing pin 96 is installed in the tab forming auxiliary part 90, and the fixing pin 96 sandwiches the swinging adhesive holding part 80 or the swinging base part 72 so that the tab forming auxiliary part 90 can be detached. It becomes the composition fixed to. With this configuration, it is possible to use the tab forming auxiliary portion 90 when using a narrow (12 mm) tape or a wide tape, and a more convenient tab forming tape cutter is configured. It becomes possible to do.
