Description

  The present invention relates to a cleaning adhesive tape roll that captures dust existing on a surface to be cleaned with a dust removal surface. More specifically, the present invention relates to a cleaning adhesive tape roll that can handle various surfaces to be cleaned such as flooring and carpets. About.

  The cleaning adhesive tape roll is wound so that the dust-removing surface faces the front side. For example, the dust-removing surface is rolled along the surface to be cleaned using a special jig. The garbage on the surface can be caught by the garbage collection surface.

  By the way, there are various types of floors, such as carpets, tatami mats, flooring, and cushion floors, depending on the purpose and location. This type of cleaning adhesive tape roll is used to rewind adhesive tape along the floor surface. , The adhesive tape becomes like a rail and sticks to the floor surface, which may cause a “rail pulling phenomenon” (see, for example, Patent Document 1). There was a need.

  Specifically, a strong adhesive type with increased adhesive strength is used on surfaces where the dust removal surface such as carpets is difficult to stick, and a weak adhesive type with reduced adhesive strength on surfaces where adhesive tapes such as flooring are likely to stick. Is used.

  However, it is troublesome if the user purchases an adhesive tape roll (or mounting jig) according to the type of floor surface. Therefore, the present applicant has proposed a versatile adhesive tape roll described in Patent Document 2.

  This pressure-sensitive adhesive tape roll is characterized in that on the pressure-sensitive adhesive layer formed on one surface of the tape base material, an elastic release agent layer is formed at predetermined intervals as a streak, and according to this, a carpet or the like When the material with unevenness is the surface to be cleaned, it directly contacts the pressure-sensitive adhesive layer beyond the release agent layer, but when the smooth material such as flooring is the surface to be cleaned, the release agent layer is in contact with the floor surface. Serves as a spacer to prevent the adhesive layer from sticking directly. Thereby, it can be used for both carpets and flooring. Moreover, since it acts as a release agent on the back surface (the other surface) of the tape base material, the back surface side peeling process is not necessary.

However, in order to avoid breakage, there are points that should be improved in terms of the selection of the release agent layer having a high stretching strength and the productivity. That is, in forming the release agent layer in a stripe shape on the adhesive layer, conventionally, while the tape substrate is running, the adhesive layer is formed in a solid shape on one surface thereof, and subsequently, the adhesive layer A release agent layer was formed by hanging the release agent melted onto the fine streaks. Therefore, release agents Application switching Lena strange, it is necessary to adjust the running speed of the tape substrate, which is to be lower productivity.

  In addition, since the release agent layer is formed on the adhesive layer, it is necessary to add an additive for improving the affinity of the interface between the adhesive and the release agent, which increases the cost.

If the spacer layer is arrange | positioned so that the adhesive layer 4 may not stick directly to a to-be-cleaned surface, the arrangement | positioning form is arbitrary according to a specification.

  As shown in FIG. 1, the adhesive tape 2 is provided with a cut 24 for cutting the used adhesive tape almost every circumference. In this example, the cut 24 is a perforation, but other cutting means may be used.

  At both ends in the width direction of the dust collecting surface 22, so-called dry edge portions 25, 25 having no adhesiveness are provided. In the present invention, the dry edge portions 25, 25 are optional components, and thus description thereof is omitted.

  Next, a method for forming the dust removal surface 22 will be described with reference to FIGS. As shown in FIG. 3, the pressure-sensitive adhesive layer 4 and the spacer layer 5 are applied onto the tape substrate 21 using a dedicated application nozzle 6.

A connection pipe for injecting the spacer agent stored in the tank T2 is connected, and a valve V2 for adjusting the flow rate is provided in the middle of the connection pipe. The tank T2 is heated by the heater H2, so that the spacer agent can be kept warm at a predetermined temperature. The tank T2, the heater H2, and the valve V2 are controlled by the control unit C.

  A conducting tube 623 (see FIG. 6) that guides the spacer agent injected from the second injection port 621 to the inner surface of the second head 62 is provided inside the second head portion 62. In this example, the second injection port 621 is provided at one location, but the number of installation is not particularly limited.

Referring to FIG. 4, the first seam member 63 is made of a flat plate made of metal, and is formed in a rectangular shape so as to be sandwiched between the inner surface of the first head portion 61 and the separator 65. At the lower end of one side surface of the first seam member 63 , a large number of first discharge ports 631 into which an adhesive is poured are provided in a comb blade shape.

  The first discharge port 631 is formed by a slit groove cut out from the lower end edge of the first seam member 63 toward the center, and is provided in parallel to each other at a predetermined interval. By supplying the pressure-sensitive adhesive from the first guide groove 614 toward the first discharge port 631, the pressure-sensitive adhesive is applied on the tape base material 21 in a streak shape, and the pressure-sensitive adhesive layer 4 is directly applied on the tape base material 2. Formed.

  With reference to FIG. 3, a second seam member 64 is provided on the other side surface with the separator 65 interposed therebetween, and is sandwiched between the inner side surfaces of the second head portion 62.

  As shown in FIG. 5, the second seam member 64 is provided with a number of second discharge ports 641 into which the spacer agent is poured. The second discharge port 641 is formed of a notch groove that is notched in a groove shape from the lower end of the second seam surface 64 toward the center, and these are provided in parallel to each other at a predetermined interval.

  According to this, as shown in FIGS. 6 and 7, the adhesive supplied from the first injection port 611 is carried to the inner surface of the first head portion 61 through the conducting tube 613 and then the first discharge. It is supplied to the outlet 631 and discharged from the tip of the first discharge port 631.

  On the other hand, as shown in FIGS. 6 and 7, the spacer agent fed from the second injection port 621 is conveyed to the inner surface of the second head portion 62 through the conducting tube 623, and then the second discharge port. 641 is supplied to the side surface of the second discharge port 641 and discharged from the tip of the second discharge port 641.

In the drawing of FIG. 6, the positions of the first discharge port 631 and the second discharge port 641 of the first seam member 63 and the second seam member 64 are the same. In order to coat thicker than the layer 4, the position of the second discharge port 641 is provided at a position higher than the first discharge port 631 of the first seam member 63 .

As shown in FIG. 7, the first discharge ports 631 and the second discharge ports 641 are alternately arranged. As a result, the streaky pressure-sensitive adhesive layer 4 is formed on the surface of the tape base material 21 by the pressure-sensitive adhesive discharged from the tip of each first discharge port 631, and the spacer layer 5 is substantially between the pressure-sensitive adhesive layers 4. At the same time, they are formed in parallel.

  According to this, since the adhesive layer 4 and the spacer layer 5 can be directly formed on the surface of the tape base material 21, not only can the productivity be improved and the product can be manufactured at a lower cost, but also the reliability of the product is improved. In addition, the melting temperature, application speed, etc. of the adhesive and the spacer agent are arbitrarily set according to the specifications.

  In this example, the coating nozzle 6 applies two types of coatings using two seam members 63 and 64, but by further increasing the seam members between the head portions 61 and 62, 3. The 4th application layer can be provided on the tape base material 21.

Apart from this, as shown in FIG. 9, the type and formation pattern of the applied product can be similarly changed by arranging the two application nozzles 6 and 6 along the flow direction of the tape base material 21. .

  Further, by adjusting the shape of the seam members 63 and 64, as shown in FIG. 8A, the spacer layer 5 is formed in a streak-like manner on the pressure-sensitive adhesive layer 4 similar to that in Patent Document 2. It is also possible. Furthermore, as shown in FIG.8 (b), the spacer layer 5 can also be provided along the inside of the ditch | groove of the adhesive layer 4 in which one part was dented.

  In this example, the pressure-sensitive adhesive layer 4 and the spacer layer 5 are formed in parallel along the feeding direction of the pressure-sensitive adhesive tape 2, but in addition to this, the pressure-sensitive adhesive layer 4 and the spacer layer 5 are inclined at a predetermined angle with respect to the feeding direction of the pressure-sensitive adhesive tape 2. May be provided, or may be formed at right angles to the feeding direction.

In this example, the position of the second discharge port 641 is provided at a high position when viewed from the discharge port of the first seam member 63, but the first discharge port 631 and the second discharge port 641 are relatively substantially the same. It may be provided on a plane. In that case, for example, by controlling the temperature and viscosity of the pressure-sensitive adhesive and the spacer agent, as well as the discharge pressure and the discharge amount, the application thickness and shape of the pressure-sensitive adhesive layer 4 and the spacer layer 5 can be changed. Such an embodiment is also included in the present invention.

  That is, as shown in FIG. 3, the control unit C controls the valves V1 and V2 to arbitrarily set the discharge pressure, amount, and the like of the first discharge port and the second discharge port. It is possible to make the layer have a higher coating thickness than the pressure-sensitive adhesive layer.

  Further, by controlling the heaters H1 and H2 by the control unit C, the temperature of the adhesive is increased to lower the viscosity, and the spacer agent is set to a lower temperature to increase the viscosity. The height of the agent can also be changed.

As shown in FIG. 10, the coating nozzle 6A has substantially the same shape as the coating nozzle 6 described above, and the same reference numerals are given to the portions regarded as the same.
