Description

  The present invention relates to a tape cutter. More specifically, the present invention relates to an adhesive roll tape in which adhesive tapes are stacked and wound, and rotatably supports the tape cutter. The present invention relates to a tape cutter that can pull out an adhesive tape to a desired length when it is pulled out and pressed against a cutter blade for cutting.

Conventionally, for example, when a pamphlet or book produced at a factory is packed and packed in a cardboard box, an adhesive roll tape is sometimes used to seal the packing box. A tape cutter is known as a tool for pulling out and cutting. This conventional tape cutter will be described with reference to FIG.
The adhesive tape 51 to be cut by the tape cutter 50 is usually used in a state of being laminated and wound around the ring body 52 to form an adhesive roll tape 53.
That is, the extending shaft 54 of the tape holder provided in the tape cutter is inserted into the central hole of the ring body 52 of the adhesive roll tape 53, and both ends of the extending shaft 54 are connected to the base of the tape cutter attached in an opposing manner. It is disposed in the support hole 57 through the insertion groove 56 of the support member 55 that is integrally formed upright.

In this state, the adhesive tape 51 pulled out from the adhesive roll tape 53 is pulled out to the position of the cutter blade 59 while being brought into contact with the lower side of the tension bar 58, and the pulled-out adhesive tape 51 is pressed against the cutter blade 59 and cut. .
This type of tape cutter is widely known in general (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 08-141979

  According to this tape cutter 50, since the extending shaft 54 of the tape holder is rotatably supported by the support hole 57, by pulling the tip 51 a of the adhesive tape 51, it is integrated with the extending shaft 54 of the tape holder. The adhesive roll tape 53 freely rotates, and the adhesive tape 51 is pulled out from the adhesive roll tape 53. Thereby, the adhesive tape 51 can be easily pulled out.

However, since the extending shaft 54 of the tape holder is rotatably supported by the support hole 57 in a free state, when the adhesive tape 51 is pulled out, the adhesive roll tape 53 rotates vigorously, and the desired length of the adhesive tape 51 is increased. It was difficult to withdraw.
That is, when the adhesive tape 51 is pulled out assuming that the length is desired, the stretching shaft 54 continues to rotate freely by the urging force of the pulling force, and even if the pulling force is released, the unnecessary adhesive tape is wasted due to inertia. The result was sent out. This is also due to the absence of a brake for stopping unnecessary rotation of the adhesive roll tape 53.

  When the adhesive roll tape 53 is replaced with a new one, the extension shaft 54 of the tape holder is removed from the support hole 57, the ring body 52 of the adhesive roll tape 53 is fitted into the removed tape holder, and then the tape holder is again inserted. Although the extending shaft 54 must be disposed from the insertion groove 56 to the support hole 57, this operation is complicated and a two-hand operation, which is relatively troublesome.

Further, when the adhesive roll tape 53 is replaced with a new one, first, the extending shaft 54 of the tape holder is disposed in the support hole 57, and then the adhesive tape 51 pulled out from the adhesive roll tape 53 is placed below the tension bar 58. It is necessary to pull out to the position of the cutter blade 59 while being in contact with the tape. However, since the lower periphery of the tension bar 58 is blocked by a pair of support members 55, it is space to pass the adhesive tape 51 through that position. For this reason, the adhesive tape 51 cannot be easily pulled out to the position of the cutter blade 59.
For this reason, there is a problem that it takes time to replace the adhesive roll tape 53.

  Further, since adhesive (glue) often protrudes from both side edges of the adhesive roll tape 53, when the adhesive tape 51 is guided via the tension bar 58, the glue protruding from both side edges of the adhesive tape 51 is tensioned. Since it accumulates and adheres to the bar 58, a cleaning operation for removing the glue from the tension bar 58 is inevitable.

  In the present invention, the adhesive tape can be accurately pulled out by a desired length, the adhesive roll tape can be easily replaced with one hand, and the glue protruding from both side edges of the adhesive roll tape adheres to the tension bar. It is an object of the present invention to provide a tape cutter that can prevent the above.

  In the invention according to claim 1, the pressure-sensitive adhesive roll tape is formed by laminating and winding the pressure-sensitive adhesive roll tape around the ring body, and the pressure-sensitive adhesive roll tape is rotatably supported, and the tip of the pressure-sensitive adhesive roll tape is pulled to thereby In a tape cutter that pulls out the adhesive tape and presses it against the cutter blade for cutting, a swing member is swingably attached to a support member formed integrally with the base in a cantilevered state, and the swing tip of the swing member The position of the support member at which the outer periphery of the adhesive roll tape can be always contacted by the weight of the tape holder and the adhesive roll tape. Attach the tension roll in a cantilevered state and pull it from the adhesive roll tape through this tension roll. A cutter blade for cutting the adhesive tape, characterized in that mounted in the state of cantilever supported by the support member.

Since the outer circumference of the adhesive roll tape is brought into contact with the tension roll by utilizing the weight of the tape holder and the adhesive roll tape, the outer circumference of the adhesive roll tape can be automatically brought into contact with the tension roll at all times. it can.
For this reason, when pulling out the adhesive tape, the adhesive roll tape can be rotated with a light force, and the adhesive tape can be easily pulled out with a light pulling force.
When releasing the pull-out force of the adhesive tape, the pressure contact force of the adhesive roll tape to the tension roll acts as a brake to stop the rotation of the adhesive roll tape instantaneously and prevent unnecessary rotation of the adhesive roll tape. The adhesive tape can be accurately pulled out by a desired length.

In addition, since the tape holder is rotatably attached to the swinging tip of the swing member in a cantilevered state, when the adhesive roll tape fitted in the tape holder is separated from the tension roll by slightly swinging the swing member, The used adhesive roll tape can be easily removed from the tape holder, and a new adhesive roll tape can be fitted at the same time.
Furthermore, by using the tension roll as a cantilever support, the adhesive tape pulled out from the adhesive roll tape can be easily pulled out to the position of the cutter blade via the tension roll.
Thereby, an adhesive roll tape can be easily exchanged with one hand without taking time and effort.

In addition, since the adhesive roll tape can be replaced only by filling from the side, the tape cutter of the present invention can be installed upward on the upper surface of the work table and can also be installed downward on the lower surface of the work table. It becomes.
In addition to this, it is also possible to stably install a tape cutter, which has been conventionally used only for mounting on a workbench, at a desired position on the workbench using a clamp member.

  According to a second aspect of the present invention, an escape groove is formed in a portion of the outer periphery of the tension roll that faces both side edges of the adhesive roll tape.

  Even when glue sticks out from both side edges of the adhesive roll tape, the glue sticking out faces the escape groove, so that the glue is prevented from adhering to the outer periphery of the tension roll.

  According to a third aspect of the present invention, the diameter dimension of the tape holder is such that both end portions are formed in a large diameter portion on the outer peripheral surface of the tape holder, and an inner portion of the large diameter portion is formed in a small diameter portion having a smaller diameter than the large diameter portion. It is characterized by.

The large diameter part can support a wide (50 mm width) adhesive roll tape, and the small diameter part can support a narrow (38 mm width) adhesive roll tape. Since it can be stably supported by the tape holder, adaptability and workability are improved.
Furthermore, if the large diameter portion is formed with a width of 50 mm and the small diameter portion is formed with a width of 45 mm, it is possible to deal with all the commercially available adhesive roll tapes that are commercially available.

  According to a fourth aspect of the present invention, in the outer periphery of the tension roll, a wide relief groove is formed at a portion facing both side edges of the wide adhesive roll tape, and at a portion facing both side edges of the narrow adhesive roll tape. A narrow relief groove is formed.

  For this reason, even if glue sticks out from both side edges of each adhesive roll tape, the glue sticking out faces each escape groove, and it is possible to prevent the glue from adhering to the outer periphery of the tension roll.

  In the invention according to claim 1, the outer periphery of the adhesive roll tape can always be brought into contact with the tension roll automatically, and when the adhesive tape is pulled out, the adhesive roll tape can be rotated with a light force. There is an advantage that the adhesive tape can be pulled out easily with a light pulling force. When the pulling force of the adhesive tape is released, the pressure contact force of the adhesive roll tape to the tension roll acts as a brake to rotate the adhesive roll tape. Is stopped instantaneously, unnecessary rotation of the adhesive roll tape is prevented, and there is an advantage that the adhesive tape can be accurately pulled out by a desired length.

  Also, since the tape holder is rotatably mounted in a cantilevered state at the swinging tip of the swing member, when the adhesive roll tape fitted in the tape holder is released from the tension roll by slightly swinging the swing member, The used adhesive roll tape can be easily removed from the tape holder, and a new adhesive roll tape can be inserted at the same time. By using the tension roll as a cantilever support, the adhesive tape pulled out from the adhesive roll tape can be tensioned. It is possible to easily pull out to the position of the cutter blade via the roll, and there is an advantage that the adhesive roll tape can be easily replaced with one hand without taking time and effort.

In addition, since the adhesive roll tape can be replaced only by filling from the side, the tape cutter of the present invention can be installed upward on the upper surface of the work table and can also be installed downward on the lower surface of the work table. It becomes.
In addition to this, it is possible to stably install a tape cutter, which has been used only on the work table in the past, at a desired position on the work table using a clamp member. is there.
