Description

  The present invention relates to a tape cutter for an adhesive tape used for packaging or the like.

  Conventionally, pressure-sensitive adhesive tapes (hereinafter referred to as “tapes”) such as OPP tape, vinyl tape, cloth tape, and craft tape have been used for packing transportation goods. There are tape cutters for cutting these tapes, such as those that can be applied while pressing the drawn tape with a roller and those that can cut the tape quickly, and those that have been devised for quick application.

  However, if the tape is firmly applied during packing, it is not easy to remove the tape, so that the package can be sealed tightly, but it also takes time to unpack. Thickness such as OPP tape is particularly difficult to peel off, and unpacking may be difficult unless it is cut with a cutter such as a cutter. However, the contents may be damaged, which is not a preferable method.

  As a device for making it easy to peel off the tape once pasted, it is conceivable to form a folded portion having no adhesiveness on the tape. This is because that part becomes a knob for peeling the tape when unpacking, and the tape can be quickly peeled off. In recent years, various tape cutters have been devised for forming a folded portion on a tape.

  Among those that have already been put into practical use, there is one in which one long side edge of the tape is folded back when being fed out, and the folded portion is formed by overlapping the adhesive surfaces. However, if the adhesive portion is to be secured within the limited tape width, the width of the folded portion must be narrowed. At the time of peeling, since it is necessary to raise the folded portion with a nail or the like in order to pinch the tape firmly with fingers, it cannot be said that the ease of peeling is sufficiently considered.

  On the other hand, Patent Literature 1 discloses a tape cutter that forms a folded portion at an end of a tape. This is because when the tape is cut, a protruding needle sticks into the end of the tape, and when the roller is rotated by lever operation, the tape where the protruding needle is inserted is drawn between the roller and the tape receiver and folded in half. By pressurizing, a bi-folded portion in which the adhesive surfaces are bonded together is formed. However, in the present invention, a special operation such as lever operation is necessary for forming the folded portion, and there remains room for study in terms of operability.

  The problem to be solved by the present invention is to provide a tape cutter capable of easily forming a folded portion serving as a peeling knob at the end of the tape in a series of operations for applying the tape.

The present invention made in order to solve the above-mentioned problems includes a tape rotating portion that rotatably holds a tape, a pressing roller for pressing the tape against a surface to be bonded, and a cutting blade that cuts the tape. In tape cutter,
A guide hole provided between the cutting blade and the pressing roller;
A slider provided with a claw protruding downward at the tip, provided to be movable back and forth in the guide hole,
A tape cutter with a folding function, wherein when the slider moves backward, the tip of the tape is drawn between the slider and the pressing roller by a claw at the tip of the slider to form a folded portion with the adhesive surface inside.
In the above and the following description, the direction toward the center of the tape is defined as downward, the opposite direction is up, the width direction of the tape is the left-right direction, the direction in which the tape is pulled out is defined as the front, and the opposite direction is defined as the rear. To do.

  In the tape cutter with a folding function according to the present invention, when the tape is affixed to the adherend surface, a folding portion with the adhesive surface inside is automatically formed at the tip of the tape by the procedure described later. Therefore, it is possible to form a folded portion having no adhesiveness on both sides of the tape end without performing a special operation in a series of operations of tape application. Thereby, since tape sticking can be performed continuously while the peeling knob is reliably formed, operations such as packing can be performed quickly.

  The tape cutter according to the present invention has been widely used conventionally, a tape rotating unit that rotatably holds the tape, a pressing roller for pressing the tape against the adherend surface, a cutting blade for cutting the tape, Can be manufactured by improving the tape cutter.

  First, a guide hole is provided between the cutting blade and the pressing roller. In the conventional tape cutter, the pressure roller and the cutting blade are generally fixed to a side plate provided integrally with the tape rotating portion (the shaft of the pressure roller is fixed to the side plate). The guide hole of the tape cutter according to the present invention can also be fixed to the side plate.

  Insert a slider that can move back and forth in the guide hole. A claw protruding downward is provided at the tip of the slider. In a normal state, the slider protrudes forward, and the tip of the tape is lightly held by a claw protruding downward from the tip.

  When sticking the tape to the adherend surface, when the tape cutter is brought close to the adherend surface, the tip of the slider is pushed by the adherend surface, and the guide hole is retracted. At that time, the tip of the tape held by the claw is also retracted and drawn between the slider and the pressing roller, and a folded portion with the adhesive surface on the inside is formed.

  In this process, it is desirable to prevent the tape from moving so that the tip of the tape is more reliably drawn between the slider and the pressing roller. Usually, since the tape roll held by the tape rotating part is gripped by the user (directly or indirectly by the tape gripping part as described later), the drawn tape does not move, When the rigidity of the tape itself is low, the tape may bend at the pulled-out portion and may come off from the claw or may not be correctly folded between the slider and the pressing roller. In such a case, it is desirable to provide a temporary fixing portion for temporarily fixing the tape near the pressing roller.

  In order to prevent the tape from coming off the pawl while the slider is moving, and to ensure that it is correctly folded between the slider and the pressure roller, it is also possible to finely control the vertical movement of the slider. is there. This can be realized by providing a rib protruding in a part in the longitudinal direction on the upper or lower surface of the slider. The rib contacts the inner surface of the guide hole when the slider moves in the guide hole, and changes the vertical movement of the slider. Therefore, by appropriately setting the rib shape (profile), the vertical movement of the slider is controlled, the tape is prevented from coming off the claw, and it is correctly folded between the slider and the pressure roller. Can do.

  Hereinafter, an embodiment of a tape cutter according to the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a state when the folded portion of the tape cutter 10 of this embodiment is formed, and FIG. 2 is a diagram showing a state when the tape cutter 10 is not attached. The tape cutter 10 of the present embodiment includes a tape rotating portion 12 that rotatably holds the tape 11, a side plate 13 that is fixed to one side surface of the tape rotating portion and is provided so as to protrude in one direction, and the side plate 13 A tape folding portion 14 provided at a tip of the tape rotating portion by a predetermined distance, a cutting blade 15 provided further above the tape folding portion 14, and a part of the tape rotating portion 12 rearward from the side plate 13. And a tape gripping part 16 provided so as to be rotatable with respect to the side plate 13.

  The tape folding portion 14 includes a guide hole 17 provided immediately below the cutting blade 15, a slider 18 provided to be movable back and forth in the guide hole, and a pressing roller provided slightly below and in front of the guide hole 17. It consists of 19. A claw 20 that protrudes downward is provided at the tip of the slider 18, and a rib 21 that extends in the longitudinal direction and protrudes from the upper surface in a part of the longitudinal direction is provided on the upper surface. FIG. 3 shows a side view of the slider 18.

  The tape gripping portion 16 is for a person who uses the tape cutter 10 to grip the tape 11 so as to be rotatable with the tape rotating portion 12. The edge opposite to the side plate 13 is provided with a standing edge protruding downward so that the tape 11 does not escape to the left and right when the tape 11 is sandwiched between the tape gripping portion 16 and the tape rotating portion 12. Yes. Further, a sliding member (not shown) for reducing resistance to rotation of the tape 11 is attached to the lower surface of the tape gripping portion 16.

  A U-shaped temporary fixing piece 22 is provided below and slightly in front of the pressing roller 19. The temporary fixing piece 22 is a member for lightly holding the tape 11 drawn between the pressing roller 19 and the temporary fixing piece 22 by a narrow linear portion in the narrow width direction at the upper part of the U shape.

  The tape turn-back portion 14 including the pressing roller 19, the cutting blade 15, the temporary fixing piece 22 and the like are provided on the side plate 13 and the side surface on the opposite side, and fixed on both sides by the second side plate 23 fixed to the side plate 13. It is gripped.

  FIG. 4 is a side view showing how to use the tape cutter 10 of this embodiment. Hereinafter, the usage will be described along (a) to (e).

(A) First, the tip of the slider 18 is brought into contact with the adherend surface 24. At this time, the slider 18 holds the tip of the tape 11 lightly by a claw 20 protruding downward from the tip.
(B) When the tape cutter 10 is pushed toward the adherend surface 24, the slider 18 moves backward through the guide hole 17. At this time, the tip of the tape 11 is retracted together with the slider 18 by the claw 20. Finally, the tip of the tape 11 is drawn between the slider 18 and the pressure roller 19 and is folded back with the adhesive portion inside. Thus, a folded portion having no adhesiveness on both sides is formed.
During the backward movement of the slider 18, the rib 21 provided on the upper surface of the slider 18 contacts the upper inner surface of the guide hole 17, so that the vertical movement of the slider 18 is controlled. By appropriately setting the shape (height profile) of the rib 21, it is possible to make it difficult for the tip of the tape 11 to come off the claw 20 of the slider 18.
(C) When the tape cutter 10 is further pressed toward the adherend surface 24, the adhesive portion of the tape 11 is pressed against the adherend surface 24 by the pressing roller 19 and is stuck thereto. Here, it is desirable that the tape cutter 10 is pulled slightly while the pressing roller 19 is pressed against the adherend surface 24 to secure the pasting portion a little longer.
(D) By pulling up the tape cutter 10 slightly and pulling it forward, the tape 11 held rotatably is rotated, and the tape is fed out while the sticking portion is fixed.
(E) The tape cutter 10 is lowered at a position where the application is to be finished, and the entire surface of the drawn tape 11 is applied to the adherend surface 24. Then, the tape cutter 10 is rotated forward, and the cutting blade 15 is applied to the tape 11 to cut the tape 11. Thus, the tape 11 is affixed to the adherend surface 24, and a folded portion serving as a peeling knob is provided at the tip.

  After the cutting, the slider 18 that has been pushed back by the tape 11 in the pasting process moves forward, and returns to the non-sticking state (FIG. 2). The slider 18 moves forward by its own weight due to the inclination of the tape cutter 10 after cutting the tape 11, but a weight may be provided on the slider 18 for easier movement, and further, an elastic member is used to always attach the slider 18 to the front. It is good also as a structure to keep up. While the slider 18 moves forward, the claw 20 at the front end slides on the non-adhesive surface of the tape 11 temporarily fixed by the temporary fixing piece 22 and finally moves upward by elasticity when it exceeds the front end of the tape 11. The tip of the tape 11 that jumps up is held.

  In the procedure as described above, the folded portion is formed in the tape cutter 10 of the present embodiment. By using this, it is possible to quickly perform operations such as packing while reliably forming the peeling knob in a series of operations of tape application.
