Background

Conventionally, in the case of such a twisted tape wound in a long length, in a state of being repeatedly wound on a reel or the like, it is necessary to ensure that the tape is not subjected to such phenomena as slipping off of a gap between the twisted tape and the reel, twisting, bending, twisting, interlacing and tangling of the tape, and loosening and scattering of the tape from the reel, and further, the tape must be smoothly drawn out, and therefore, the tape is frequently used in the following cases: the soft PVC is used as a resin material for a covering material, a highly shaped metal wire is used as a core material, the twisted tape is wound around a plastic reel or the like, and the wound tape is mounted on a binding machine, and the object to be bound is bound at a high binding frequency of 50 to 100 times per minute.

No. 2000-95267 propose extrusion-type coreless twisted tapes in which a core wire is not used and wing portions and a core portion are integrally extruded by using a resin such as an olefin.

That is, the following laminated twisted tape is disclosed in japanese unexamined patent publication No. 60-190654: the core wire is made of synthetic resin wires such as polyester, the covering material is made of synthetic resin materials such as polyethylene, polypropylene and polyester, the corrosion is difficult, fingers can be prevented from being injured, the electric leakage cannot be caused, and the metal detector can be used for metal detectors.

On the other hand, U.S. Pat. No. 4797313 and japanese patent No. 2520403 disclose a coreless twisted tape obtained by extrusion molding without using a core wire in a core portion; also disclosed is a twisted tape which is a thermoplastic polymer containing, for example, at least 50% or more of polyalkylene terephthalate, styrene-acrylonitrile polymer, polystyrene, polyvinyl chloride, which contains a polymer having a glass transition temperature higher than about 30 ℃ and exhibiting glass/rubber transition behavior at a temperature of about 10 to 30 ℃, characterized in that: the binding device has the advantages that firstly, the binding can be carried out manually or by a mechanical device, secondly, the binding, the unbinding and the rebinding can be carried out in a large range of temperature, the binding can be firmly maintained, thirdly, the binding device can be used in a microwave oven, fourthly, even if the high-temperature treatment is carried out, the firm binding can be maintained, and the like.

These twisted tapes, which have no core wire in the core portion or no wire in the core wire of the core portion and are made of a non-halogen material such as olefin resin as a material for the covering material, are significantly improved in performance and can be used while being cut into a short-sized shape while sufficiently and normally exhibiting the performance. However, in contrast to a conventional twisted tape in which a wire is used as a core wire and PVC is used as a covering material, since the core portion is substantially weaker in shape than the wire and the covering material is harder than the soft PVC, the tape is not suitable for being wound into a wound shape such as a reel winding, and there are many problems that the twisted tape slips down into a gap portion of the reel, the tape itself twists and bends, the tape twists and entangles, and is loosened and separated from the wound state at the time of winding, transportation, and use, and as a result, the tape cannot be smoothly taken out.

Detailed Description

The non-metal twisted strip 1 of the present invention is generally in the state of an extruded non-metal twisted strip 1a as shown in fig. 2 or in the state of a laminated non-metal twisted strip 1b as shown in fig. 3. The former belt 1a can be obtained by extruding and integrally molding, for example, a mixed composition containing a non-halogen resin as a main component, into a shape having a core portion 3 and wing portions 4; the latter strip 1b may be formed as follows: for example, the core 3 is provided with a non-halogen plastic core wire 5, and a plastic film covering material 6 made of a non-halogen resin or a covering material 6 made of paper, nonwoven fabric or the like laminated on the inner surface of the core is laminated on the upper and lower sides thereof. As shown in fig. 1, the non-metal twisted tapes 1a or 1b are wound in a bundle shape in a long length on a winding frame (reel) and supplied.

The non-metal twisted tape 1 of the present invention is attached to a binding machine 11 shown in fig. 4, for example, and is not particularly limited in length, and can be used in a long-sized wound state 2 of about 500m to 5000m, for example, and therefore, binding performance after binding by the binding machine 11, for example, a torsional strength in a torsional state shown in fig. 5 (represented by a binding force measured according to the method shown in fig. 6) is necessarily excellent, but the following problems are not expected to occur: with regard to the winding shape 2 of reel winding, round-rod core winding, and the like, the phenomenon of slipping of the twisted belt 1 into the clearance of the reel 2a, twisting and bending of the belt 1, twist interlacing and tangling between the belts 1, or loosening and scattering of the belt 1 from the reel 2a in transportation or use, which problems must be solved.

When the non-metal twisted tape 1 is wound back to the winding shape 2 such as a reel winding, the phenomenon that the binding tape 1 slips into the gap of the reel 2a, the tape itself twists and bends, the tape 1 is twisted and entangled with each other, and the tape 1 is loosened and separated from the reel 2a is likely to occur at the time of winding back, transportation, and use.

As a result, for example, when the twisted tape 1 slips and twists in the gap between the spools or the twisted tapes 1 are twisted and entangled or tangled, the twisted tape 1 receives uneven resistance when the twisted tape 1 is drawn out from the wound state 2, and the twisted tape 1 may be bent leftward or rightward.

Further, the twisting band 1 is bent in the winding direction with respect to the winding shaft 2a, and causes a binding failure.

In contrast, the scattering and loosening of the twisted tape 1 in the winding form 2 due to the poor shape-forming and shape-holding properties becomes a cause of difficulty in twisting and wing breakage in twisting of the binding machine.

The present inventors have made extensive studies to solve the above problems, and as a result: it was found that by controlling the side bending degree α and the bending radius r in the winding direction in the case of pulling out the twisted tape 1 within a certain range, a good pulled-out state can be obtained without causing a binding failure.

That is, the degree of curvature α to the left and right with respect to the drawing direction shown in fig. 8 must be maintained within 10 degrees or 10 degrees. The reason for this is that: when the degree of curvature exceeds 10 degrees, the binding machine 11 cannot firmly clamp the strap, and a poor binding often occurs.

In addition, it is necessary to ensure that the bending radius r in the winding direction is within the range of 50 to 200 mm. The reason for this is that: if the radius r exceeds 200mm, the twisted tape is bent upward, and the binding machine 11 is difficult to continuously bind; on the other hand, if the radius r is less than 50mm, the twisted tape bends downward, and therefore, a trouble often occurs when the binding machine 11 continuously binds the tape.

On the other hand, the phenomenon of twisting and wing breakage which are difficult to bind with the binding machine 11 was investigated and found: the twisted belt 1 having the twisting strength, i.e., the binding force, of the twisted belt 1 within the range of 5 to 15N rarely causes such a problem.

Based on the above-described results, the inventors of the present invention have further studied the shape of the binding band 1 in the wound shape 2, in which the twisted band 1 is less likely to slip and twist into the gap of the reel 2a, or the twisted band 1 is less likely to twist, interlace, and tangle.

The result is: the total width (w in fig. 2 and 3) of the twisted belt 1, which is less likely to slip and twist or twist and interlace, is 1.50 to 20.0mm, and more preferably 2.5 to 20.0 mm.

If the total width w is less than 1.50mm, it is difficult to function as the wing part 4 of the twisted belt 1, thereby increasing the frequency of slipping and twisting, twisting and interweaving, and entanglement. If the total width w is greater than 20mm, the width of the wing portion 4 is also increased, and a failure often occurs in the twist binding of the twisted tape 1.

Further, the results of the investigation of the thickness of the wing part 4 are: the maximum thickness of the wing part 4 is 0.02 to 0.2mm, preferably 0.03 to 0.2 mm.

If the thickness of the wing portions 4 is less than 0.02mm, it is difficult to perform the function of the wing portions 4, and, for example, there is a problem that the twisted tape falls into a gap of the reel 2a due to vibration. If the thickness is more than 0.2mm, a problem such as wing breakage occurs during binding.

Next, the results of the study on the core 3 indicate the following facts: the relationship between the maximum thickness h and the total width w of the core 3 must be taken hold of.

That is, in terms of stability of the twisted tape 1 when wound into the wound shape 2 and ease of binding, the maximum thickness h (height) of the core 3 must be increased when the width w is large, and decreased when the width w is small.

The results of this study were: when the maximum thickness h of the core 3 is 0.04 to 0.30 times, more preferably 0.05 to 0.25 times, the total width w of the twisted tape 1, both the winding performance and the binding performance can be satisfied to the maximum.

When the maximum thickness h of the core 3 is not 0.04 times the total width w, the twisted tape is almost plate-like and shows a stable state on the reel, but the fulcrum at the time of twisting becomes wide in terms of bundling, so that it is difficult to twist, and undesirable bundling is likely to occur.

Conversely, if the maximum thickness h exceeds 0.3 times the total width w, it is preferable in that the bundling is easy, but the state of the wound shape 2 becomes unstable due to the protrusion of the core 3 during the winding, and as a result: when winding, the twisted belt 1 is liable to slide, slide down into the gap, twist and interlace between the belts 1, and tangle.

Further, the shape of the core 3 may be a single-sided convex shape as shown in fig. 2 in consideration of the winding shape 2 in particular, but the shape is not particularly limited thereto as long as the thickness h is 0.04 to 0.3 times the total width w.

Next, the inventors of the present invention studied a phenomenon that the binding tape 1 in the winding shape 2 is likely to be separated and loosened. The result is: in order to prevent the occurrence of the unraveling and loosening, the binding tape 1 must have a shape forming property of 90% or more or 90% or more and a shape retaining property of 70 to 95%.

Further, the inventors have found, after examining the torsional strength at which no binding failure occurs during binding: the binding failure of the twisted belt 1 having a binding force (torsional strength) of 5 to 15N is minimized.

The shape-imparting property, shape-retaining property, and bonding force within the desired value range can be obtained in the twisted tape 1 having a tensile elastic modulus of 5000 to 30000 MPa.

In addition, the tensile elastic modulus may be obtained by any one of the following means: first, a plastic core 5 strongly stretched 10 times or more is used (fig. 3), or second, a mixture with a filler added thereto is extruded and then stretched 2.5 times or more, and then, the resulting product is stretched 2.5 times or more (fig. 2).

As for the torsional strength (binding force), in the mechanical binding, the torsional strength (binding force) is preferably 5 to 15N. In other words, in the mechanical binding, a twisted tape having a torsional strength (binding force) of less than 5N causes a binding failure such as loosening immediately after binding. In addition, for twisted belts to which a high load exceeding 15N is applied at the time of twisting, the result of mechanically loading is: an undesirable bundled state occurs, such as the bundled portion being bundled into a dough.

Furthermore, the twisted tape having a torsional strength (binding force) of less than 5N has a problem in terms of the function of the twisted tape 1, such as coming off the object 7 to be bound or being disengageable with a small amount of force. Although the twisted tape having a number of twist tapes exceeding 15N has no problem in terms of the coupling force, it has a disadvantage that it is difficult to unwind and reuse the twisted tape because it is tied too tightly.

On the other hand, with regard to the shape retention, if the shape retention does not reach 70%, the tape 1 is often separated from the reel 2 a; if it exceeds 95%, the frequency of slipping down into the gap and twist-interlacing and entanglement between the belts increases due to the lack of reducing force.

In addition, the twisted tape 1 having a shape less than 90% is difficult to wind along the reel 2a and the like during winding, and the tape 1 itself has a large repulsive property, which causes slipping, twisting, interlacing, and tangling to the reel 2 a.

Next, the twisted tape material of the present invention will be described by using a non-metal twisted tape 1a of an extrusion type (hereinafter referred to as an extrusion tape) shown in fig. 2 and a non-metal twisted tape 1b of a lamination type (hereinafter referred to as a laminate tape) shown in fig. 3.

The extrusion band 1a is composed of a mixed composition containing a non-halogen thermoplastic resin as a main component, and 1 or 2 or a mixture of 2 or more of the following types can be used as the thermoplastic resin: polyester resins such as polyethylene terephthalate and polybutylene terephthalate, polyamide resins such as nylon 6 and nylon 6.6, polyacetal resins such as polyvinyl formal and polyvinyl butyral, polyolefin resins such as polyethylene and polypropylene, acetic acid resins such as cellulose acetate, polyethylene resins such as vinylon, biodegradable resins such as starch and polylactic acid, regenerated cellulose resins such as rayon, propylene resins such as copolymers of polyacrylonitrile, polyacrylonitrile and a propylene monomer, polycarbonate resins, and polyphenylene sulfide resins.

In addition to the thermoplastic resin, the extrusion belt 1a may be formed by appropriately selecting a mixture containing the following materials, as required: silicic acid such as colloidal silica, aluminum silicate such as kaolin, magnesium silicate such as talc, silicate such as mica powder, carbonate such as calcium carbonate and magnesium carbonate, metal oxide such as calcium oxide, magnesium oxide, zinc oxide and titanium dioxide, metal hydroxide such as magnesium hydroxide and aluminum hydroxide, filler such as barium sulfate and carbon black, lubricant such as stearic acid and zinc stearate, plasticizer such as trimellitate, phthalate, fumarate, adipate, azelate, sebacate, polyester and stearate, and pigment.

The difference in thickness between the core 3 and the wings 4 is caused by the shape: by providing the thickness difference, rigidity is imparted to the core 3, and flexibility is imparted to the wing 4. It should be noted that fig. 2 shows the shape of the core portion 3 having a single-sided convex shape, but the shape of the core portion 3 is not necessarily limited thereto, and may be a double-sided convex shape, and it is important to provide the core portion so as to have a certain thickness difference from the wing portions 4. The core 3 is located at approximately the center in the drawing, but the position thereof is not necessarily limited to the center, and may be an end. The number of the end portions is not limited to 1, and 1 end portion may be provided, or a plurality of end portions may be provided at a desired position.

In addition, the extrusion belt 1a may be formed by extruding the core portion 3 and the wing portions 4 by a twin-screw extruder with different mixing in order to further enhance the rigidity of the core portion 3.

On the other hand, the laminate tape 1b is constituted as follows: a plastic core 5 made of a non-halogen resin which is easily plastically deformed is sandwiched between 2 sheets of a covering material 6 used as a wing portion made of a plastic film made of a non-halogen resin, or a thermoplastic resin such as PE laminated on the inner surface of a paper, a nonwoven fabric, or the like. As the plastic film made of the non-halogen resin, an olefin film such as PE or PP, a polyester terephthalate film such as PET or PBT, an acetic acid film, a laminate of the above, or a vapor-deposited metal film using the above as a base layer, each having a thickness of 10 to 100 μm, is mainly used; but is not necessarily limited thereto as long as the performance as the wing portion can be maintained. The laminated 2 sheets of cover material may be the same material or may be different materials such as paper and PET film.

The core material 5 is preferably a thin plastic wire made of a non-halogen resin which is strongly stretched 10 times or more and is easily plastically deformed to have a diameter of 0.3 to 1.8 mm; the main component of the non-halogen resin is polyolefin resin such as polyethylene and polypropylene, polyolefin resin such as polybutylene terephthalate and polyethylene terephthalate, polyamide resin, and the like.

The twisted strap 1 of the present invention obtained by bundling with the bundling machine 11 shown in fig. 4, for example, can perform continuous bundling by inserting the opening portion of the bag-like object to be bundled 7 shown in fig. 5 into the bundling groove 13 of the bundling machine body 11 in the bundling machine 11 shown in fig. 4. The twisted tape 1 of the present invention has performance necessary for binding and can be stably drawn out from the winding shape 2, so that binding failure can be minimized even if work is performed at a high speed of 50 to 100 times/min.

The twisted tape 1 of the present invention is used in the winding shape as described above; for example, the desired length may be drawn out from the wound shape for manual twisting for gardening and the like, and the wound shape may be cut and used. In addition, even with a cut product produced in advance for use such as hand twisting, since the cutting operation or the cutting operation of cutting the cut product from the large roll, the medium roll, and the small roll in the above-described steps can be performed extremely smoothly with good winding performance and good drawing performance, a cut product with good appearance and low production cost can be obtained.

Examples

As shown in fig. 6, the loop portion 8 of the twisted tape 1 pulled out from the object 7 to be bundled was cut at a position facing the joint portion 9 to be a sample.

The assay was performed as follows: the ring ends obtained by cutting were fixed to upper and lower chucks of a tensile tester, respectively, and stretched at a speed of 300 mm/min to measure the bonding force.

Method for calculating shape retention and shape retention

The shape-imparting property and the shape-retaining property (the state of being retained in the wound shape) were calculated by the following formulas.

Formability (ease of bending) B (%) { (l)₀-l₁)/(l₀)}×100

Shape retention (ease of winding along a reel) R (%) {1- (l)₃-l₂)/l₂}×100

l: distance between calibration points

l₀: linear distance between calibration points when not under load

(thickness measurement by dial gauge when not loaded-specimen thickness. times.2)

l₁: linear distance between calibration points under load

(measurement of thickness by dial gauge under load-specimen thickness. times.2)

l₂: straight line distance between calibration points measured immediately after placement

l₃: straight line distance between calibration points after 2 minutes of standing

Method for measuring shape-imparting and shape-retaining properties

As shown in fig. 7, the twisted tape 1 removed from the wound material was cut exactly to a length of 80mm, and a calibration line M having a certain distance l between calibration points was marked at the center of the sample (fig. 7 (a)). ② the sample is slowly folded so that the terminals are overlapped, the dial gauge 14 for measuring the load 80g specified by JISZ0237(JISB7503) is used to clamp the position of the calibration line M, and the linear distance l between the calibration points at the time of no load is read according to the scale of the dial gauge 14₀And linear distance l between the calibration points under load₁The formability is obtained according to the above formula (fig. 7 (b)). Thirdly, the dial gauge 14 is taken down, and the linear distance l between the calibration points measured immediately after the placement is measured by the angle square₂At the same time, the linear distance l between the calibration points after being left for 2 minutes was measured₃The shape retention was measured according to the above formula (fig. 7 (c)).

Method for measuring lateral curvature

As shown in fig. 8, the measurement of the camber refers to: the left or right lateral curvature of the twisted strip 1 with respect to the direction of withdrawal of the twisted strip 1 is measured when the twisted strip 1 is withdrawn from a winding. That is, the tape 1 having a length of about 20cm is drawn from the wound object, the thick paper 15 for measuring the lateral camber is placed as shown in the drawing, and the lateral camber of the tape drawn from the wound object is measured along an arbitrary line shape marked on the thick paper 15. Method for measuring bending radius

As shown in fig. 9, the measurement of the bending radius refers to: the bending radius r is measured with respect to the winding direction. That is, the length corresponding to one turn wound on the winding is slowly wound back and cut. The radius r to which the sample is to be applied is the bending radius r when the sample is fitted to the corresponding arc of the thick paper 16 as shown in the figure using the thick paper 16 for measuring the bending radius with the arc previously prepared.
