Description

The present invention relates to adhesive Tepuro Le for cleaning the adhesive surface of the adhesive tape is wound so as to face outward, and more particularly relates to a hand cutting property of good adhesion Tepuro Le.

  Garbage such as hair and lint attached to carpets, etc. tends to get entangled in the pile and cannot be removed with a vacuum suction cleaner. Therefore, as a tool for efficiently and easily removing this kind of dust, an adhesive cleaning tool that has an adhesive surface such as an adhesive tape in contact with the surface to be cleaned and captures the dust on the adhesive surface. Is provided.

  For example, as disclosed in Patent Document 1, the cleaning tool includes an adhesive tape roll wound so that the adhesive surface faces the front side, and a cleaning tool body that rotatably supports the adhesive tape roll. The mainstream is that an adhesive tape roll is inserted into the cylindrical tape support portion of the cleaning tool body.

  According to this, by rolling the adhesive tape roll on the surface to be cleaned, it is possible not only to easily and efficiently capture dust on the adhesive surface, but also to peel off the dirty outermost adhesive tape after use. It is widely used not only for home use but also for business use because it is easy to clean.

  However, the conventional adhesive tape has the following problems. That is, this adhesive tape roll is provided with cuts (perforations) for cutting almost every round so that dirty adhesive tape can be separated therefrom, but hair, lint, etc. When adhering so as to straddle the cut, when the adhesive tape is cut off, the tape may tear along the longitudinal direction (feeding direction) from the middle of the cut.

  Another problem is that when the conventional adhesive tape roll is rolled in the direction opposite to the winding direction (unwinding direction) in the initial use state where the adhesive force is strong, the adhesive tape is removed from the edge of the cut. There may be a so-called rail pulling phenomenon that sticks to the surface in a band shape.

JP 2002-315718 A

The present invention was made in order to solve the above problems, its object is to hand tearability is good, providing an adhesive Tepuro Le does not cause the rail pulling phenomenon.

To achieve the above object, the present invention provides an adhesive tape one surface of the tape-like substrate is a pressure-sensitive adhesive surface in the adhesive tape roll for cleaning formed by winding as the outer and the adhesive surface, the adhesive The tape is formed with one cut for cutting substantially every circumference, and a cutting guide member made of a film base that is tougher than the adhesive tape along the core side of each cut. It is characterized by being provided in a strip shape along the width direction of the adhesive tape.

In the present invention, the pressure-sensitive adhesive tape has a non-adhesive portion having a predetermined width where no pressure-sensitive adhesive is applied to both ends of the pressure-sensitive adhesive tape, and the cutting guide member excludes the non-adhesive portion. It is preferable that it is provided on the adhesive surface of the adhesive tape.

Moreover, the aspect in which the adhesive surface which consists of an adhesive material whose adhesive force is weaker than the adhesive material of the adhesive surface of the said adhesive tape is formed also on the said cutting guide member in this invention.

According to the present invention, the cutting guide member that is tougher than the adhesive tape is disposed along the core side of each cut, so that the cutting guide member can be used even if the hair is attached across the cut. Because the end is protected, it does not cause vertical tearing. Further, since the adhesive force at the tape end is weakened by the cutting guide member, the rail pulling phenomenon can be reliably prevented.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a pressure-sensitive adhesive tape roll according to an embodiment of the present invention, and FIGS.

  As shown in FIG. 1, this adhesive tape roll 1 has an adhesive tape 2 in which an adhesive surface 22 is formed on one surface of a tape-like substrate 21, and the adhesive surface 22 is on the front side (the upper surface side in FIG. 1). It consists of what was wound in roll shape along the core 3 so that it may face.

  Usually, a core made of cardboard is used for the core 3, but other materials such as a synthetic resin may be used. In addition, a so-called coreless type in which only the adhesive tape 2 is wound in a roll shape without using the core 3 may be used, and in the present invention, the core 3 is an arbitrary component.

  The base material 21 is made of paper, for example, and as shown in FIG. 2A, an adhesive surface 22 coated with an adhesive material is formed on one surface (surface). The type of the adhesive material may be arbitrarily selected, such as strong adhesion or weak adhesion, according to the cleaning surface to be used (for example, flooring or carpet). Moreover, the material of the base material 21 may be a resin film other than paper.

  In this example, the adhesive surface 22 is applied in a uniform strip shape along the feeding direction of the adhesive tape 2, but it may also be striped or streaked, and is an adhesive for catching dust. If it functions as the surface 22, the coating form such as the coating thickness and shape can be arbitrarily changed according to the specification. Moreover, in this example, the non-adhesive parts 23 and 23 in which the adhesive material is not apply | coated are provided in the both ends of the adhesive surface 22 of the base material 21. FIG.

  On the other surface (back surface) of the base material 21, a peeling treatment surface 24 made of, for example, a silicon resin is provided. The release treatment surface 24 is provided so that the adhesive tape on the upper layer side and the adhesive tape on the lower layer side do not stick when the adhesive tape 2 is laminated in a roll shape. In the case of weak adhesion, the release treatment surface 24 may not be provided.

  Referring to FIG. 1 again, the adhesive tape 2 is provided with a cut line 4 for cutting almost every circumference. In the present invention, the cut 4 refers to a cutting means used for cutting the adhesive tape 2 along the width direction, and includes, for example, an array of long hole slits and an intermittent slit such as a perforation.

  In this embodiment, the cut 4 is provided substantially parallel along the width direction of the adhesive tape 2, but may be formed in an oblique direction other than this. Furthermore, a short cut for triggering cutting at a part of the end of the adhesive tape 2 may be used.

  A cutting guide member 5 is provided on the front side (adhesive surface 22 side) of the adhesive tape 2 along the core side (reverse feed direction side) of the cut 4. The cutting guide member 5 is made of a synthetic resin film such as PET (polyethylene terephthalate) or PP (polypropylene), and is preferably made of a tough material having higher tensile strength and tear strength than the tape base material 21. Moreover, it is more preferable to add an antistatic agent so that dust does not easily adhere.

  The cutting guide member 5 is preferably colored in a different color from the adhesive tape 2 so that the cut 4 of the adhesive tape 2 can be easily identified at a glance. According to this, even if dust adheres to the adhesive surface 22, the cutting guide member 5 can be easily discriminated, so that the cut 4 in the vicinity thereof can be reliably found. Note that the cutting guide member 5 may be colorless and transparent when cost is important such as business use.

  The cutting guide member 5 is formed in a strip shape having a width W (FIG. 2A) in the feeding direction of 1 to 10 mm. The cutting guide member 5 is more preferably set to W = 2 to 5 mm (particularly, W = 3 to 4 mm).

  According to this, when the length L is less than 1 mm, the toughness of the cutting guide member 5 becomes weak, and there is a possibility that the cutting of the adhesive tape 2 cannot be guided correctly. On the other hand, when the length L exceeds 10 mm, not only the material cost increases, but also the adhesive area decreases and the amount of dust captured may decrease.

  In this example, the surface of the cutting guide member 5 (the upper surface in FIG. 2A) is a non-adhesive surface. For example, as shown in FIG. 51 may be formed so that the cutting guide member 5 can also catch dust. In this case, in order to prevent the rail pulling phenomenon, it is preferable to use an adhesive material that is weaker than the adhesive material of the adhesive surface 22.

  According to this, even if hair or the like adheres across the end of the adhesive tape 2, the outermost adhesive tape 2 is peeled off by the cutting guide member 5 being provided along the cut line 4. At this time, since the cut 4 is guided by the end of the cutting guide member 2, it is possible to reliably prevent the adhesive tape 2 from being torn in the middle or torn in the vertical direction.

Next, with reference to FIG. 3 and FIG. 4, the manufacturing method of this adhesive tape roll 1 is demonstrated. 3, the apparatus for manufacturing adhesive tape roll have the meanings indicated schematically, FIG. 4 (a) ~ (c) is an operation explanatory view of a manufacturing apparatus for cutting guide member. In addition, this adhesive tape roll manufacturing apparatus is equipped with the housing | casing which is not shown in figure, and is integrated in it.

  As shown in FIG. 3, the apparatus for manufacturing the adhesive tape roll 1 is such that the adhesive surface 22 faces the front side of the adhesive tape 2 fed out from the raw roll 20 wound in multiple layers so that the adhesive surface 22 faces inward. A tape conveyance path 60 for winding the tape on the back, a cut forming means 70 for forming the cut 4 in the adhesive tape 2, and a delivery means 80 for sending the cutting guide member 5 toward the adhesive tape 2.

The tape transport path 60 includes two transport rollers 6 2 and 62 for transporting the adhesive tape 2 drawn from the raw roll 20 toward the take-up roller 61, and a constant tension for the adhesive tape 2. A tension roller 63.

In this example, the transport rollers 6 2 and 62 are rotationally driven via a driving means (not shown), and feed the adhesive tape 2 in a certain direction (from right to left in FIG. 3). The tension roller 63 pulls the adhesive tape 2 through a spring means (not shown) so as to have a constant tension. The specific configuration of the transport rollers 6 2 and 62 is arbitrary.

The cut forming means 70 includes a rotary blade 71 in which a blade 73 is provided in a part of a rotating body, and a feed roller 72 arranged to face the rotary blade 71 with the adhesive tape 2 interposed therebetween. 71 and the feed roller 72 are provided between the transport rollers 6 2 , 62.

  The rotary blade 71 is a so-called die-cut roll in which a blade 73 is integrally formed on a part of a cylindrical roll body, and the blade tip is formed in a comb blade shape to form a cut 4 (perforation). . In this example, a die cut roll is used as the blade 73, but a Thomson blade or the like may be used. The specific configuration of the blade 73 may be arbitrarily selected according to the shape of the cut 4. That is, for example, a straight blade is used to form the slit-like cut 4.

  The feed roller 72 is a receiver side roller of the rotary blade 71 and is rotationally driven by a driving means (not shown). In this example, the feed roller 72 reliably receives the rotary blade 71 composed of a die-cut roll and forms a perforation 4 so that the roll body (for example, anvil roll) whose surface is a high-precision smooth surface. Is preferably provided.

  The rotation of the rotary blade 71 and the feed roller 72 is preferably controlled synchronously with each other via a clutch means (not shown). That is, as the pressure-sensitive adhesive tape 2 is wound in a roll shape, the winding diameter increases and the position of the cut 4 is shifted. Therefore, the rotation timing of the rotary blade 71 is shifted by the clutch means, and control is performed so that the cut line 4 is formed approximately every one circumference.

  In this example, the cuts 4 are formed almost every round length. For example, the cuts 4 are provided at intervals of less than one round length (360 °), and the next layer is formed on a part of the outermost adhesive tape 2. A part of the adhesive tape 2 (in this example, the cutting guide member 5) may be exposed.

  According to this, since the cut guide member 5 appears on both sides of the cut 4 by providing the so-called reverse step structure cut 4, there is no adhesive force in the vicinity of the cut 4 and the rail pulling phenomenon is reliably performed. Can be prevented.

  The feeding means 80 includes a raw roll 81 of a cutting guide member around which a sheet-like cutting guide member 5a (cutting guide member sheet 5a) is wound, and a cutting guide member from the original roll 81 toward the cut forming means 70. Conveying rollers 82 and 83 for feeding out the sheet 5a and a guide plate 84 for guiding the cutting guide member sheet 5a are provided.

  The conveying rollers 82 and 83 are rotationally driven by a driving unit (not shown), and send the cutting guide member sheet 5a toward the cut forming unit 70 at a predetermined interval (W: 1 to 10 mm). In this example, auxiliary rollers 85 and 86 are provided upstream of the conveying rollers 82 and 83.

  The guide plate 84 comprises a so-called slide having one end (upstream side) disposed toward the exit side of the transport rollers 82 and 83 and the other end disposed obliquely toward the entrance side of the feed rollers 71 and 72. The cutting guide member sheet 5a is guided along the upper surface.

  The tip 841 of the guide plate 84 (on the rotary blade 71 side in FIG. 3) is curved so as to feed the cutting guide member sheet 5a substantially horizontally toward the rotary blade 71 and the feed roller 72.

  According to this, the front end of the cutting guide member sheet 5 a guided by the guide plate 84 can be reliably guided between the rotary blade 71 and the feed roller 72, and the cutting guide member sheet 5 a is attached to the adhesive surface 22. Can do.

  Next, an example of a procedure for forming the cutting guide member 5 will be described with reference to FIGS. 3 and 4A to 4C. First, as an initial setting, the adhesive tape 2 is set in advance along the tape transport path 60, and its tip is fixed to a winding core (not shown) of the winding roller 61.

  Further, the cutting guide member sheet 5 a is set on the conveying path of the conveying rollers 82 and 83, and the leading end thereof is pulled out to the leading end 841 of the guide plate 84. Furthermore, the formation width W of the cutting guide member 5 is set (in this example, W: 1 to 10 mm).

  When the start button (not shown) is operated after the initial setting is completed, the control means drives the drive means (not shown), whereby the adhesive tape 2 starts to be gradually wound along the take-up roller 61.

  As shown in FIG. 4A, when the adhesive tape 2 is drawn out to a constant length of substantially one circumference, the control means issues a command to the conveying rollers 82 and 83, and in response to this, the conveying rollers 82 and 83 Is a predetermined length of the cutting guide member sheet 5a based on a preset value.

  The fed cutting guide member sheet 5a moves along the guide plate 84 and is fed between the rotary blade 71 and the feed roller 72 as shown in FIG. At this time, the cutting guide member sheet 5 a is introduced between the rolls while the tip thereof is bonded along the adhesive surface 22 of the adhesive tape 2.

  When the rotary blade 73 further rotates and the blade 73 comes directly below, it is inserted into the adhesive tape 2 to form the cut 4, and at the same time, the cutting guide member sheet 5a is substantially cut. Further, when the feed roller 72 rotates, the cutting guide member 5 substantially cut as shown in FIG. 4C is peeled off in a state of being bonded to the adhesive tape 2 along the cut line 4, and the adhesive tape. 2 is wound on the winding side.

  Through the series of operations described above, the cut 4 formation operation and the cutting guide member 5 bonding operation are performed simultaneously. The control means controls the clutch means (not shown) in consideration of the increase in the winding diameter described above. The rotation speeds of the rotary blade 71 and the feed roller 72 and the feed speeds of the transport rollers 82 and 83 are adjusted as appropriate so that a cut 4 is formed for each circumferential length of the adhesive tape 2 regardless of the winding diameter. Yes.

In this embodiment, the adhesive tape roll manufacturing apparatus is configured to simultaneously perform the cutting guide member 5 and the cut 4 forming operation, but only the cutting guide member 5 may be attached. Further, only the cutting guide members 5 are affixed at regular intervals so as to be aligned in the radial direction, and after winding up, a cutting blade is inserted along the cutting guide member 5 from the outer periphery of the adhesive tape roll 1 to form a cut 4. You may make it do.
