Description

  The present invention is applied to a tape cutter of a wide adhesive tape winding body frequently used for packing or the like, and in particular, the side line is folded along the longitudinal side portion of the adhesive tape drawn from the adhesive tape winding body. The present invention relates to a handy type pressure-sensitive adhesive tape cutter in which a non-adhesive portion obtained by polymerizing pressure-sensitive adhesive surfaces is formed, and a pressure-sensitive adhesive tape is attached to an object, and then the peeling operation can be easily performed when peeling the surface.

  Adhesive tape is made by applying an adhesive mainly composed of rubber or synthetic resin to one side of a thin film-like base material such as cloth, cellophane, kraft paper, rubber or polyvinyl chloride. This pressure-sensitive adhesive tape is distributed in the form of a pressure-sensitive adhesive tape wound around a roll. Such adhesive tapes are used for various adhesive applications, and wide adhesive tapes having a tape width of about 50 mm are often used especially when packing cardboard boxes.

  In addition, when using such a wide adhesive tape for packaging, etc., the adhesive tape is pulled out from the adhesive tape wound body and cut to a desired length and attached to an object. As an easy-to-work tape cutter, when applying adhesive tape, it is possible to apply it simply by holding the tape cutter in your hand and pressing the adhesive surface of the adhesive tape drawn to the tip of the tape against the object. There is something.

  In such a tape cutter, since the shape of the pressure-sensitive adhesive tape drawn out from the pressure-sensitive adhesive tape winding body is a flat plate, the pressure-sensitive adhesive tape folds down when it comes out of the pressure-sensitive adhesive tape winding body and hangs down. In the pasting, an inefficient method is adopted in which the tip of the tape is peeled off with a tip of a fingertip, pinched with a fingertip, pulled out and pasted.

  Therefore, recently, a method of providing arms to support the pulled-out tape on both side ends of the part to which the tape is attached has been adopted so that the tape does not stick to the outer peripheral surface of the adhesive tape wound body. Since the tape is flat, if you pull it out from the supporting arm for a long time, it will fold and hang, and it may stick to other objects and become inoperable. For this reason, the supporting arm must be provided near the leading end of the drawn tape, i.e., at a position close to the tape cutting blade. Even if you try to apply it by pressing it against the object to be applied, the arm you support will be in the way and you will not be able to apply it properly. The fact was that it was not.

  In addition, the tape cutting blade attached to the tape cutter is mainly exposed and involves danger. However, there is a cover plate that can be swung via a spring above the tape cutting blade. However, even when the tape cutter is not used, it moves if a finger touches it, exposing the tape cutting blade, and perfect safety cannot be obtained.

Therefore, as an improvement of such a tape cutter, for example, a tape guiding portion for attaching the drawn adhesive tape is formed at one end of the main body to be attached to the adhesive tape wound in a roll shape, and the tape is formed at the tip thereof. A cutting blade is provided, and the surface to which the drawn-out adhesive tape is attached is formed in a shape in which the portion inside the edge is raised, and a tape holding portion provided with a plurality of protrusions on the surface covers the surface to which the adhesive tape is attached The cover plate with a plurality of protrusions on the surface is formed on both sides of the tape holding part. A structure having a structure in which it is sandwiched between the connecting arms and engaged with each other, and is pivotably attached to the main shaft that penetrates the connecting arms and is fixed to the side surface of the tape holding portion is introduced. (For example, refer to Patent Document 1).

The protrusions 26A and 26B are in contact with the side surface of the adhesive tape winding body 4 attached to the tape holder 11 to restrict the position of the adhesive tape winding body 4 to the support plate 2A side. When the adhesive tape 3 is pulled out from the adhesive tape wound body 4 by gripping the tape, the overlapping portion 3E is more reliably formed. Further, the protruding portions 26A and 26B also play a role of locking the adhesive tape wound body 4 so that the adhesive tape wound body 4 does not fall out of the support portion 5.

Further, a convex portion 9 </ b> B that can contact the outer peripheral surface of the adhesive tape wound body 4 is formed on the inner side surface 9 </ b> A of the tape cover 9. Due to the presence of the convex portion 9B, when the user holds the tape cover 9 and pulls out the adhesive tape 3 from the adhesive tape winding body 4, the adhesive tape winding body 4 is pressed by the tape cover 9. Since it can prevent still more reliably, it can make it easier to pull out the adhesive tape 3. FIG.

  This adhesive tape cutter 1 has a curved shape from the tip of the cut portion 6 (left tip in FIG. 2) to the tip of the tape cover 9 on the support portion 5 side (right tip in FIG. 2). Is configured to be easily operated for attaching the adhesive tape 3 to an object.

  Next, a specific operation of the adhesive tape cutter 1 according to the first embodiment will be described.

  First, the tape cover 9 is rotated outward with respect to the main body bracket 2 to form a space between the support portion 5 and the tape cover 9, and the non-adhesive of the adhesive tape 3 drawn out from the adhesive tape winding body 4. The roll core 4A of the adhesive tape wound body 4 is mounted on the support portion 5 of the adhesive tape cutter 1 so that the surface 3B faces the tape cover 9 side.

  Next, the adhesive surface 3 </ b> A of the adhesive tape 3 is positioned on the bending roll 15, the adhesive tape 3 is inserted between the folding member 16 and the laminating roll 17, and the adhesive tape 3 is further inserted into the first pressing roll 31. The pressure-sensitive adhesive tape 3 is set so that the pressure-sensitive adhesive surface 3A faces and the non-adhesive surface 3B of the pressure-sensitive adhesive tape 3 faces the second pressing roll 32. Thereafter, the tape cover 9 is returned to cover a part of the outer peripheral surface of the adhesive tape wound body 4.

  In this state, the user inserts a finger into the hollow portion 13, holds the adhesive tape cutter 1 so as to hold the tape cover 9, and pushes the adhesive tape 3 against the object via the second pressing roll 32. When the adhesive tape cutter 1 is pulled forward while being applied, the adhesive tape 3 is pulled out of the adhesive tape wound body 4 and attached to the object. At this time, in the adhesive tape 3, first, the flange 15 </ b> B end of the adhesive tape 3 is locked by the flange 15 </ b> B of the bending roll 15, and the position of the adhesive tape 3 is regulated. By this regulation, the edge 3C on the flange 15B side of the adhesive tape 3 is released from the end on the support plate 2A side of the bending roll 15 and becomes free. That is, the folding roll 15 supports the adhesive surface 3A of the adhesive tape 3 while leaving a predetermined folding width at the edge 3C of the adhesive tape 3, and bends the folded width portion.

  Next, the pressure-sensitive adhesive tape 3 that has passed through the bending roll 15 has the non-adhesive surface 3B of the edge portion 3C abutted against the bending angle holding portion 21 of the folding member 16, and the bending angle of the edge portion 3C bent by the bending roll 15 is maintained. In this state, the first bending guide member 22 is reached. In the first bending guide member 22, the edge 3C of the adhesive tape 3 is further bent so that the bending angle of the edge 3C of the adhesive tape 3 is about 120 degrees. Next, the adhesive tape 3 is inserted between the second bending guide member 23 and the laminating roll 17, and the edge portion 3 </ b> C of the adhesive tape 3 is folded back at approximately 180 degrees. And the adhesive surfaces 3A of the folded part of the adhesive tape 3 are stuck here, and the superposition | polymerization part 3E is formed.

  Next, the pressure-sensitive adhesive tape 3 on which the overlapping portion 3E is formed first reaches the first pressing roll 31, then passes between the first pressing roll 31 and the second pressing roll 32, and the second The pressing roll 32 is pressed against the object and is affixed to the object. The adhesive tape 3 is continuously pulled out from the adhesive tape wound body 4 in this state until it is cut by the cut portion 6 and is stuck to the object.

  Thereafter, in order to cut the adhesive tape 3 on which the desired application has been completed with the cut portion 6, the user first holds the adhesive tape cutter 1 that is gripped (held with the right hand) at the cut portion 6. The adhesive tape 3 is easily cut at the cut portion 6 when rotated counterclockwise. At this time, the cut adhesive tape 3 is pressed against the object by the pressing portion 8. For this reason, after affixing the adhesive tape 3 to the object, the user can surely affix the adhesive tape 3 to the object even if the user does not bother pressing the adhesive tape 3 against the object. it can. Moreover, the adhesive tape 3 can be affixed to an object more smoothly and easily without being bent carelessly.

  In a series of operations for forming the overlapping portion 3E on the edge 3C of the adhesive tape 3, the convex portion 9B formed on the tape cover 9 comes into contact with the outer peripheral surface of the adhesive tape winding body 4, and the adhesive tape is wound. Since the accommodation space for accommodating the body 4 is formed, the adhesive tape winding body 4 can be prevented from being pressed by the tape cover 9 when the adhesive tape 3 is pulled out from the adhesive tape winding body 4. Therefore, the adhesive tape 3 can be more easily pulled out. Moreover, since the position of the adhesive tape winding body 4 attached to the tape holder 11 is regulated by the protruding portions 26A and 26B, the overlapping portion 3E is reliably formed at the end portion 3C of the adhesive tape 3. The

  Further, in the above operation, the adhesive surface 3A of the adhesive tape 3 comes into contact with the surface of the folding roll 15, but the contact area with the adhesive surface 3A by the plurality of grooves 15A formed on the surface of the folding roll 15. Therefore, the force required when pulling out the adhesive tape 3 from the adhesive tape wound body 4 can be reduced. Further, a member (for example, a roll) for strongly pressing the adhesive tape 3 against the bending roll 15 is not provided. Therefore, the adhesive surface 3A of the adhesive tape 3 is not strongly bonded to the surface of the bending roll 15, and the adhesive tape 3 can be pulled out smoothly.

  Moreover, although the adhesive surface 3A of the adhesive tape 3 will also contact the surface of the 1st press roll 31, the 1st press roll 31 is short in length, and the some groove | channel 31A is formed in the surface. Therefore, as a result of being able to reduce the contact area with the adhesive surface 3A of the adhesive tape 3, the force required when pulling out the adhesive tape 3 from the adhesive tape wound body 4 can be further reduced, The adhesive tape 3 can be pulled out more smoothly.

  By the above process, the adhesive tape 3 on which the superposed part 3E is formed is affixed to the object, so that the superposed part 3E serves as a knob for making the adhesive tape 3 easy to peel off. The adhesive tape 3 can be easily peeled off. Since there is a mark line 3F in the vicinity of the picking allowance (that is, the overlapping portion 3E), the existence of the picking allowance can be easily known, and the binding release operation can be performed more easily.

  Moreover, this superposition | polymerization part 3E can be formed automatically, when sticking the adhesive tape 3 on a target object.

In Example 1, one end of the laminating roll 17 in the axial direction is attached to the support plate 2A of the main body bracket 2. However, as shown in FIG. It may be rotatably attached to the side surface of 119 in a cantilever state.

The tape cover 119 is rotatably attached to the main body bracket 2, and the tape cover 119 is separated from the main body bracket 2 around the rotation axis of the pressing roll at the tip of the main body bracket 2, as shown in FIG. When it rotates, a wide space is generated between the bonding roll 17 and the main body bracket 2. In FIG. 22, the adhesive tape 3 drawn out from the adhesive tape wound body 4 is bonded to the folding member 16 so that the adhesive surface 3 </ b> A of the adhesive tape 3 is positioned on the folding roll 15. The pressure-sensitive adhesive tape is inserted between the roll 17, and the pressure-sensitive adhesive surface 3 </ b> A of the pressure-sensitive adhesive tape 3 faces the first pressure roll 31 and the non-pressure-sensitive surface 3 </ b> B of the pressure-sensitive adhesive tape faces the second pressure roll 32. 3 is set. Here, since the laminating roll 17 is attached to the side surface of the tape cover 119, a wider space is formed between the support portion 5 and the tape cover 119 as described above. For this reason, when the above-mentioned adhesive tape 3 is inserted between the folding member 16 and the laminating roll 17 from the folding roll 15 and passes between the first pressing roll 31 and the second pressing roll 32. In addition, it becomes extremely easy to insert the adhesive tape 3 between the folding member 16 and the laminating roll 17 disposed on the side surface of the tape cover 119, and the laminating member 17 even if the tape is sticky. It becomes easy to mount the tape on the tape.

  Further, in Example 1, one end of the tape cover 9 is provided on the other end of the support plate 2A of the main body bracket 2 and the side plate 2C so as to be rotatable by a pin 25, but as shown in FIG. It can also be attached to the main body bracket 2 so as to be rotatable about the axis of the pressing roll 32 as a fulcrum. By mounting in this way, when the tape cover 119 is rotated outward from the main body bracket 2, a wider space can be formed between the main body bracket 2 and the bonding member 17. 3 is further easily inserted between the folding member 16 and the laminating roll 17.

  In Example 1, since it was necessary to shorten the 1st press roll 31 in order to make the contact area with 3 A of adhesive surfaces of the adhesive tape 3 small, the bonding roll 17 is the 1st press roll. It was longer than 31. As described above, since the adhesive tape 3 can be more easily inserted and attached to the cut portion 6, the length of the first pressing roll 31 and the laminating roll 17 need not be important. Either can be long. For example, in order to make the adhesive tape 3 more stable, both the first pressing roll 31 and the bonding roll 17 may be lengthened.

  Further, the laminating roll 17 provided on the side surface of the tape cover 119 is accurately guided to a position facing the folding member 16 when the tape cover 119 covers a part of the adhesive tape winding body 4. As shown in FIG. 22, the main body bracket 2 may be provided with a notch 120 that terminates in the vicinity of the folding member 16.

  In addition, when the laminating roll 17 is inserted into the cut 120, the tape cover 119 is cut at a position where the tape cover 119 does not press the adhesive tape wound body 4 even if the tape cover 119 covers a part of the adhesive tape wound body 4. May be provided. In this way, when the adhesive tape 3 is pulled out from the adhesive tape winding body 4, the adhesive tape winding body 4 is rotatably attached to the support portion 5 even when the tape cover is gripped. Since the tape winding body 4 can be prevented from being pressed by the tape cover 119, the adhesive tape 3 can be pulled out more easily and smoothly.

As shown in FIG. 21, the protruding portion 26 provided on the tape cover 119 is formed larger than that of the first embodiment so as to be able to contact the tape holder 11 or the flange portion 12. . Further, the tape holder 11 has the support portion 5 extended in the width direction so that the protruding portion 26 contacts the tape holder 11 without contacting the tape winding body 4, and the protruding portion 26 is provided at a position avoiding the tape winding body. Note that the flange portion 12 of the support portion 5 may be extended in the width direction so that the protruding portion 26 abuts on the flange portion 12.
By comprising in this way, the space beyond the thickness of the adhesive tape winding body 4 will be formed between the tape holder 11 or the flange part 12, and the tape cover 119, and the adhesive tape winding body 4 When the pressure-sensitive adhesive tape 3 is pulled out, the pressure-sensitive adhesive tape wound body 4 can be more reliably prevented from being pressed by the tape cover 119, so that the pressure-sensitive adhesive tape 3 can be more easily pulled out.

  Further, when the protruding portions 26A and 26B are both formed so as to be able to contact the flange portion 12 or the tape holder 11, when the tape cover 119 covers a part of the adhesive tape wound body 4, the protruding portions 26A and 26B are Since both ends of the tape cover 119 are brought into contact with the flange portion 12 or the tape holder 11, the left and right balance is improved, and the adhesive tape 3 can be pulled out more easily and smoothly.

  In Example 1, the tip of the protrusion 26 is formed in an arc shape and the apex is in contact with the support. However, the shape is not limited to this, and a concave arc is formed at the tip as shown in FIG. It may be formed and in surface contact with the circumferential surface of the support.
