Description

  The present invention relates to a mat roll in which various fiber mats are wound in a cylindrical shape, for example, a packing body of a mat roll in which a glass fiber chopped strand mat or a glass fiber continuous strand mat is wound, and a packing method thereof.

  Various fiber mats such as glass fiber chopped strand mats and glass fiber continuous strand mats are used in a wide range of applications, for example, as one of various FRP reinforcing materials. The manufacturing process of the glass fiber chopped strand mat manufactured from the long glass fiber is as follows. First, a continuous glass strand obtained by collecting several tens to several hundreds of glass fibers having a diameter of several μm to several tens of μm is cut into a length of about 10 mm to 100 mm using a cutter or the like to form a chopped strand. The mat is produced by uniformly dispersing the obtained chopped strands in a non-directional direction, spraying a thermoplastic resin powder such as a polyester resin powder, heating and melting, and solidifying by press cooling. For glass fiber continuous strand mats, continuous glass strands melted and spun in a glass melting furnace are irregularly arranged, and then an emulsion such as vinyl acetate resin is applied as a binder, and moisture is removed in the drying process. After the film is formed by evaporation, it is produced by press cooling and solidifying.

  Usually, the width dimension of these fiber mats made of glass is about 1000 mm to 2000 mm. The length of this fiber mat of several tens to several hundreds of meters is wound around a core tube a plurality of times to form a roll (hereinafter referred to as a mat). Called a roll). Next, in order to protect the surface of the mat roll, it is stored in a bag made of a resin film such as polyethylene, and then a plurality of long mat rolls are stored in a cardboard box while being laid, and then loaded on a pallet. The entire load is stored and transported in a state of being fixed so as not to be displaced by being bound by a polypropylene band (PP band) or the like.

  However, in such a conventional packing form, since a large number of cardboard boxes are loaded, the cardboard box located at the lower stage is easily crushed by the weight of the mat roll above it, and the mat roll stored is deformed, and the product There was a risk of quality loss. In addition, such a packing form has a problem that the cost of the packing material is expensive and a storage place for the packing material is required. In addition, cardboard boxes are often regarded as disposables as consumables. However, it is desirable to simplify materials required for product packaging as much as possible from an environmental viewpoint, resource saving, and cost reduction.

For this reason, the invention which solves the problem of the packing body of the mat roll which enclosed the above several fiber mats has been performed until now. For example, Patent Document 1 discloses an invention in which a cardboard box is unnecessary because a plurality of mat rolls are arranged substantially in parallel on a pallet and then wound around with a belt-like body. Further, in Patent Document 2, in a mat roll package in which a plurality of mat rolls produced by winding a fiber mat into a cylindrical shape are arranged substantially in parallel on a pallet, each mat roll has a sticky shape. A mat roll package is disclosed which is held together via a consistent film. In these inventions, the fiber mat package is formed by arranging a plurality of mat rolls substantially upright on a pallet in parallel and then tightly wrapping the bundle around it with a stretch film, thus eliminating the need for cardboard boxes. There is an advantage of being.

  However, in the conventional packing form, the long ends of the mat roll are deformed with time due to the shrinkage of the used stretch film with time, and the fiber mat is moved from the mat roll at a speed of several tens of meters / minute. When releasing at this time, the long ends of the mat roll are not released at the same speed, and as a result, there is a possibility of causing a problem that the released fiber mat is wrinkled or torn. On the other hand, if the periphery of the bundled mat rolls is not tightly wound with a stretch film or the like, there is a possibility of causing problems such as load collapse.

  Therefore, the present inventors have repeated research, and even in the case of a fiber mat package that has been kept packed for a long period of time, the long ends of the mat roll are deformed by the shrinkage of the tightly wrapped packaging material. When the mat roll is released to make a fiber mat, the fiber mats at both ends of the mat roll are released at the same speed, there is no risk of wrinkling, and the mat roll is stored without further worries. It is an object of the present invention to provide a fiber mat packaging body and a packaging method thereof that can reduce costs and save resources because no packaging material such as a cardboard box is used.

  The fiber mat packaging body of the present invention has a base, a substantially cylindrical mat roll around which the fiber mat is wound, and a tightening body, and a plurality of mat rolls are integrated in a substantially upright state on the base. A fiber mat package in which mat rolls are formed by tightening together with a tightening body, and the belt-like body is accumulated so as to have an uncovered portion of at least 5 cm from the upper end of the stack on the base. It is characterized in that the side peripheral surface of the body is covered and tightened, and the covering dimension by the band-shaped body is at least 50% or more of the height dimension of the integrated body.

  Here, it has a base, a substantially cylindrical mat roll around which a fiber mat is wound, and a tightening body, and a plurality of mat rolls are accumulated in a substantially upright state on the base and integrated by the tightening body. A fiber mat package that is tightly formed to form an assembly of mat rolls, the side circumferential surface of the assembly being such that the strip has at least 5 cm of uncovered portion from the upper end of the assembly on the base. Collecting a plurality of mat rolls each having a long shape around which a fiber mat is wound up means that the covering is tightened and the covering dimension by the belt is at least 50% or more of the height dimension of the aggregate. The fiber mat packaged body, which is arranged on the base in a state close to upright and is fastened together by the tightening body to form an assembly of mat rolls, is the top of the stack, that is, the mat roll in a state close to upright. Starting from the upper end of the long side, The belt-like body that is tightened so as not to cover at least 5 cm in the height direction of the stack, that is, toward the long bottom end of the mat roll, is 50% or more of the full length of the mat roll. This means that a plurality of bundled mat rolls are coated and fastened so as to have the following width.

  As for the belt-like body to be tightened by covering, any material, thickness dimension, and width dimension can be used in the present invention as long as they have strength and durability sufficient to fix the fiber mat and further have shielding properties. It can be used as such. For example, a stretch (stretchable) film, a fiber reinforced composite sheet, or a stretchable rubber-like woven fabric can be used as necessary. The belt-like body may also serve as a tightening body.

  Various methods are possible for the method of tightening the covering. That is, a belt-like stretch film or other belt-like body may be wound around a mat roll assembly that is bundled into a plurality of pieces, and may be covered and tightened by fixing the end of the belt. Then, by sequentially covering the side peripheral surface of the mat roll assembly with a jig or a plurality of processed sheets that can fix the end portions or the peripheral portions to each other, finally It may be in a state of covering and tightening. Further, after covering with a sheet made of a heat-shrinkable material, the sheet may be stretched and tightened by an appropriate amount by applying appropriate thermal energy to the sheet.

  According to the study by the present inventors, the belt-like body to be covered and tightened starts from the upper end of the stack, and is fastened so as to have an uncovered portion of at least 5 cm or more in the height direction of the stack, that is, downward. Thereby, it can suppress that the both ends of the elongate direction of the mat roll which forms an integrated body deform | transform with a temporal pressing force. And in addition to that, the covering width dimension in the longitudinal direction of the mat roll assembly by the band-like body to be tightly covered is at least 50% or more of the height of the assembly, that is, the total length in the longitudinal direction of the mat roll, A plurality of mat rolls can be firmly fixed as an integrated body in a state where the mat rolls are bundled together so that the mat rolls do not collapse during inventory or transportation.

  From such a point of view, in the fiber mat package of the present invention, a fiber mat in which a plurality of mat rolls are stacked on a base in a substantially upright state and tightened together by a tightening body to form an aggregate of mat rolls. It is more preferable that the belt-shaped body that covers and tightens the side peripheral surface of the assembly is fastened so as to have an uncovered portion of at least 10 cm or more downward from the upper end of the assembly.

  In addition, when a plurality of mat rolls are bundled and fixed together to form an integrated body, if a band having a predetermined fixing property and having a higher flexibility is used, a band to be tightened by covering. The covering dimension in the height direction of the aggregate by the body, that is, the longitudinal direction of the fiber mat is preferably at least 70% or more of the total height of the aggregate.

  Further, in the present invention, if the plurality of bundled mat rolls are securely fixed and do not cause any trouble when the mat roll is released, the upper end of the stack is used as a starting point, and the stack There is no problem even if the non-covering portion provided in the height direction is provided at another position on the side peripheral surface of the mat roll assembly. For example, there may be an uncoated portion at the lower end of the mat roll assembly. Further, the belt-like body to be tightly coated does not necessarily need to uniformly cover the side peripheral surface portion of the mat roll assembly. If necessary, there may be a difference in the coating thickness, and even if there is a part that is not partially coated, there is no problem as long as other coating materials are used in combination.

  Further, in the fiber mat package of the present invention, a coating material having another appropriate function is used for the non-covered portion of the side peripheral surface of the aggregate that is not covered by the belt-like body that covers and tightens the mat roll assembly. It does not prevent the accumulation of the aggregate, that is, the mat roll. However, it is preferable that the covering material having another appropriate function used in this case (hereinafter referred to as an auxiliary covering material) does not exert the tightening effect on the mat roll. An example of such a case is a case where a stretch film is used as a belt-like body to be covered and tightened, and a polyethylene bag is used as an auxiliary covering material. Here, the polyethylene bag has a function of protecting the fiber mat from dirt and the like, but does not have a function of tightening the mat roll. With such a configuration, the auxiliary covering material may have a bag-like form for storing the mat roll, or may be a simple sheet-like form. When a bag-shaped covering material is adopted as the auxiliary covering material, the opening of the bag after the mat roll is accommodated is sealed and fixed by heat treatment, an adhesive, a pin, a jig, or the like. Alternatively, it may be pushed into a hollow portion provided in the core member of the mat roll, or may be folded under the mat roll and fixed by the weight of the mat roll without performing such a thing.

  Moreover, the fiber mat package of the present invention can be applied after making it into a roll, regardless of the configuration of the fiber mat. For example, if it is made of glass fiber, the mat roll can be applied softly, such as a glass fiber chopped strand mat or a glass fiber continuous strand mat, and its long end portions are easily deformed.

  In addition to the above, the fiber mat package of the present invention is effective against the collapse of the package even when the height of the mat roll assembly is in the range of 500 mm to 3000 mm. The mat is not deformed or damaged when the roll is released later.

  If the total height of the mat roll assembly, that is, the overall length in the longitudinal direction of the mat roll is less than 500 mm, the cost effectiveness is reduced even if the present invention is applied. Further, if the overall length of the mat roll in the longitudinal direction exceeds 3000 mm, the total height of the aggregated body is too large in transportation and storage, which may cause problems in workability such as transportation and transportation of the mat roll.

  In addition to the above, the fiber mat package of the present invention can be applied to any shape or material of glass fiber as long as the fiber mat is made of glass fiber. It is possible to make it easy to use a mat material having an excellent quality without causing any trouble when storing or transporting various fiber mats to be used.

  Specifically, the glass fibers constituting the fiber mat that can be used as the fiber mat package of the present invention include E glass (non-alkali glass composition), AR glass (alkali resistant glass composition), C glass (acid resistant alkali). Lime-containing glass composition), D glass (composition realizing low dielectric constant), S glass (composition realizing high strength and high elastic modulus), T glass (composition realizing high strength and high elastic modulus) and H glass (Composition realizing high dielectric constant).

  Various organic chemicals may be applied to the surface of the glass fiber constituting the fiber mat. Specifically, the sizing agent, the antistatic agent, the surfactant, the polymerization initiator, the polymerization inhibitor, and the antioxidant. It may be coated with an agent, a film forming agent, a coupling agent or a lubricant, and if necessary, a water reducing agent, a fluidizing agent, a thickening agent, a waterproofing agent, a rust prevention agent, a curing accelerator, a curing delay An agent, slag, fly ash, silica fume, colorant or quick setting agent may be mixed.

  Moreover, the glass fiber which comprises a fiber mat is not specifically limited also about the fiber diameter and length of a filament, and fiber cross-sectional shape. That is, a monofilament glass fiber having a diameter of several μm to several tens of μm can be used, the length thereof is arbitrary, and the cross-sectional shape thereof is also a perfect circle, a substantially oval, a flat circle, a hollow circle, or a substantially Appropriate application is possible for shapes such as rectangles.

  In addition to the above, the fiber mat package of the present invention can be firmly fixed by bundling a plurality of fiber mats after appropriately forming a mat roll if the belt-like body covering and tightening the aggregate is an elastic film. Therefore, it is preferable that the packaging is not damaged during the conveyance.

  Here, the belt-like body for covering and fastening the integrated body is an elastic film means that a so-called stretch film is used as a member for covering and fastening a mat roll. This stretch film is preferable because it has a function of protecting the mat roll in addition to the functions of covering and tightening.

  As the material of the stretch film, any material can be used as long as it can be stretch-wrapped, but a polyethylene film or a polypropylene film is preferable. In particular, a polyethylene film is preferable because it has high extensibility and hardly breaks. The film thickness of the stretch film is preferably in the range of 5 μm to 100 μm, particularly in the range of 10 μm to 40 μm, considering the strength of the packaging and the ease of tearing when unpacking.

  The number of times the stretch film is wound around the mat roll may be appropriately selected according to the size, weight, number of bundles, and the like of the entire mat roll. Further, it is preferable that the stretched film is wound so that the side peripheral surface portion of the pallet corresponding to the base for installing the mat roll substantially upright and the lowermost portion of the mat roll are integrated. That is, the side of the pallet and the lowermost part of the mat roll are wound together so as to be stretched together, and the winding is performed so that the number of windings is 5 to 20 times. Since the pallet and the mat roll are integrated, it is difficult to collapse the cargo, which is preferable. Further, for example, in a case where a structure such as a receiving tray or the like is interposed between the base and the mat roll, a stretch film is attached to these three or more in order to integrate the mat roll, the auxiliary structure and the base. It is preferable to wrap around the related member. Further, such an integrated configuration is preferable because the lowermost portion of the mat roll is in a state where it is not directly subjected to the force of the band-like material that is covered and tightened by being surrounded by a base, a tray or the like.

  In addition to the above, the fiber mat package of the present invention can be used as an aggregate of mat rolls when forming the fiber mat package if the mat roll is obtained by winding the fiber mat around a core material. Therefore, it is preferable because the workability when standing upright is good, and the operation of applying the band-like material to be covered and tightened can be performed quickly and efficiently.

  Here, the mat roll is a roll obtained by winding a fiber mat around a core material. The mat roll having a cylindrical shape formed by winding the mat around the core material relates to the present invention. It is a thing.

  As the core material for winding the fiber mat, any material can be adopted as long as the fiber mat can be wound. Specifically, a material composed of a light metal material such as aluminum, plastic, paper, or the like can be used as appropriate. Further, the shape is not particularly limited as long as it can be wound. However, from the viewpoint of cost and the like, it is preferable to use a so-called paper tube in which paper is formed in a cylindrical shape as a core material and wind the fiber mat into a roll to form a mat roll.

  Further, in the fiber mat package of the present invention, as a base used for bundling a plurality of mat rolls to be substantially upright, a surface on which the mat rolls are loaded substantially upright has flatness, and a plurality of mat rolls are loaded. Any material and shape that has an appropriate structural strength that does not increase even if it is easy to transport using a forklift or other transport means. Even it can be adopted. As a material applicable to the base, for example, a material such as wood, metal, synthetic resin, or FRP can be used alone or in combination. Moreover, as a shape of a base, if it has what is called a pallet shape, since it is suitable also for conveyance, it is suitable.

  Further, the fiber mat package of the present invention may have a configuration in which an auxiliary component, an auxiliary jig, and the like for arranging the mat rolls in a substantially upright manner are appropriately attached as necessary. For example, in the present invention, a tray-like component whose periphery is further bent upward may be disposed on the upper portion of the base, and a light metal frame may be provided on the periphery of the base. Even if these incidental components are fixed to the base and integrated, or can be removable with bolts or the like, there is no problem.

  For the saucer-like structure, for example, if the height of the circumference is 5 cm or more, preferably 10 cm or more, it is preferable because the load does not easily collapse due to rolling when transported by a forklift or the like. Any material can be used as long as it has a certain strength. For example, wood, cardboard, metal, synthetic resin, FRP, etc. can be used alone or in combination. However, it is most preferable to use corrugated cardboard in consideration of cost and the like.

  In addition to the above, for such incidental components, a roof-like protective plate, a side protective plate, or the like applied to protect the upper portion of the fiber mat package can be used as appropriate.

  The fiber mat packaging body of the present invention is characterized in that any of the above fiber mat packaging bodies is formed by an operation of covering and fastening the aggregate while applying a tensile force to the belt-like body.

  Here, forming any one of the above fiber mat packaging bodies by applying and tightening the aggregate while applying a tensile force to the belt-like body means, for example, a mat roll bundled while being pulled from one end side of the belt-like body to be covered and tightened This indicates that packing is performed by firmly fixing a plurality of mat rolls, for example, by covering the integrated body by wrapping a belt-like body around it.

  As a method of applying a tensile force, it may be performed by human power, or may be performed by continuously applying a constant force by a mechanical device such as a robot, or a method combining both. There may be. Moreover, when performing such operation, it is also possible to adjust the tensile force as appropriate on the upper side or the lower side of the mat roll assembly as necessary, and to intentionally apply a different stress depending on the winding site.

  In addition to the above, the fiber mat packing method of the present invention can be applied to the mat as long as the operation of covering the belt-like body while applying a tensile force is performed by the winding operation of the belt-like body to be tightened multiple times. This is preferable because the tightening force applied to the roll assembly can be appropriately adjusted by the number of windings.

  The operation of coating the belt while applying a tensile force is performed by the winding operation of the belt for tightening the coating multiple times, when the belt for tightening the coating is wrapped around the mat roll assembly. This means that the belt-like body to be covered and tightened is laminated by performing a plurality of winding operations.

  Thus, it becomes easy to comprise the packing body of a strong fiber mat by setting it as the state laminated | stacked on the side peripheral surface of the several mat roll integration | stacking body with which the strip | belt body to carry out covering | tightening tightening was bundled.

  (1) As described above, the fiber mat package of the present invention has a base, a substantially cylindrical mat roll around which the fiber mat is wound, and a tightening body, and a plurality of mats on the base. A fiber mat packaging body in which rolls are stacked in a substantially upright state and tightened together by a tightening body to form an assembly of mat rolls, and the belt-shaped body is at least 5 cm or more from the upper end of the stack on the base Since the side peripheral surface of the assembly is covered and tightened so as to have an uncovered portion, and the covering dimension of the band-shaped body is at least 50% or more of the height-direction dimension of the assembly, the package body for transportation and storage There is no damage or collapse of the mat, and even in the mat releasing operation, the released mat does not cause quality problems such as wrinkles on the appearance.

  (2) Further, the fiber mat package of the present invention can be transported and stored even when the height of the mat roll assembly is in the range of 500 mm to 3000 mm, and can overcome the problem when the mat roll is released. it can.

  (3) Further, in the fiber mat package of the present invention, if the fiber mat is made of glass fiber, the glass fiber produced for the fiber mat can be made into a mat having excellent quality, and further in the process of using the mat. Thus, it is possible to efficiently produce a product using a fiber mat having a stable quality.

  (4) Further, in the fiber mat package of the present invention, if the belt-like body that covers and tightens the integrated body is an elastic film, a plurality of mat rolls to be coated can be surely adjusted by adjusting the pressing force applied to the mat. It becomes possible to fix to.

  (5) Furthermore, if the mat roll is a roll obtained by winding the fiber mat around a core material, the mat roll may be displaced when the mat roll is coated with a belt-like body to be coated and tightened. This is preferable because the efficiency of the covering operation can be improved without tilting.

  (6) The packing method of the fiber mat package of the present invention is to form the fiber mat package by an operation of covering and tightening the aggregate while applying a tensile force to the belt-like body. It is easy to fix the mat rolls in a bundle without depending on the number, and the fiber mat package can be formed quickly.

  (7) In the fiber mat packing method of the present invention, if the operation of covering the belt-like body while applying a tensile force is performed by the winding operation of the belt-like body to be tightened multiple times, It is easy to adjust the fastness of the fiber mat, and it is possible to reinforce locally vulnerable areas.

  The fiber mat package of the present invention and the packaging method thereof will be specifically described below based on examples.

  FIG. 1 is a perspective explanatory view of a fiber mat package 10 of the present invention. FIG. 2 is a partial cross-sectional view of the fiber mat package 10 of FIG. In this package 10, a cardboard tray 12 is arranged on a wooden pallet 11, and 16 glass fiber chopped strand mats made of E glass are wound around a paper tube as a fiber mat above the tray 12. The taken mat rolls 13 are arranged in parallel (4 in the vertical direction and 4 in the horizontal direction) in a substantially upright state.

  These 16 mat rolls 13 are manufactured with the same specifications, and the total length L in the longitudinal direction is 1440 mm, the outer diameter is 270 mm, and the mass is 32 kg. Each of the mat rolls 13 is 530 mm wide and 1800 mm long. The opening 15 of the polyethylene bag 15 is pushed into the cavity of the paper tube 14 at the lower end 13b of the mat roll and fixed.

  As shown in FIG. 2, a stretch film (polyethylene with a thickness of 25 μm) is placed around the bundle 130 of mat rolls 13 having a height T of 1300 mm from the lower end 13b of the mat roll stored in the mat roll package 10. Film) 16 is coated. Therefore, in this fiber mat package 10, 140 mm from the upper end 13a to the lower end 13b of the stack 130 of mat rolls 13 in a substantially upright state intentionally covers the uncovered portion 10a that is not covered with the stretch film 16. Provided. On the other hand, the stretch film 16 also covers a part of the pallet 11 as a base for the lower end 13b of the aggregate 130 of the mat rolls 13, whereby the mat roll 13, the tray 12 and the pallet 11 are integrated. It has a structure to do.

  Subsequently, the process is concretely demonstrated in order about the packing method of the fiber mat package 10 of this invention.

  First, molten glass of E glass material previously melted in a glass melting furnace is drawn out from the bushing and spun to have a count of 22 Tex, and the obtained continuous strand is cut into a length of 50 mm by a glass fiber cutting device.

A large number of glass chopped strands obtained from long glass fibers in this way are dispersed uniformly and non-directionally, and then a polyester resin thermoplastic resin powder is applied to the surface to bond the glass strands together. A plurality of strand mats (weight per unit area: 110 g / m ² ) are produced.

  Next, the obtained glass fiber chopped strand mat was wound up 200 m around a paper tube 14 as a core material to produce a mat roll 13 (total length 1440 mm, outer diameter 270 mm), and then a polyethylene having a width of 530 mm and a length of 1800 mm. The bag 15 is placed and the opening is pushed into the cavity of the paper tube 14 and stopped.

  Then, 16 mat rolls 13 filled with the polyethylene bag 15 are prepared, and these are placed on a corrugated cardboard tray 12 arranged on the pallet 11 so as to be in a substantially upright state of 4 in the vertical direction and 4 in the horizontal direction. The mat rolls 13 packed in the polyethylene bags 15 are arranged so that the outer peripheral surfaces thereof are in contact with each other. In this state, a plurality of mat rolls 13 are bundled, and a single PP (polypropylene) band 17 is wound around the circumferential surface of the bundled mat rolls 13 on the assembly 130 side. When the PP band 17 moves to a stretch wrapping machine (also referred to as a stretch wrapper, stretch machine, or stretch wrapping machine), problems such as collapse of a plurality of substantially upright mat rolls 13 packed in a bag occur. This is intended to prevent this.

  Next, a plurality of bag-packed mat rolls 13 in a substantially upright state are placed in a state where they are bundled with the PP band 17 and placed together with the pallet 11 on a Stretch film packaging machine with a forklift. 11 is covered with a stretch film 16 so as to be integrated with a part of 11 and a peripheral portion having a height T from the lowermost part of the tray 12 and the mat roll 13 to 1300 mm. In this way, a dimension of 1300 mm is covered with respect to the total length 1440 mm of the aggregate 130 of the mat roll 13, and 90% or more of the total length of the aggregate 130 of the mat roll 13 is covered. .

  The mat roll 13 is covered with the stretch film 16 while applying a tensile force (12 kgf) along the stretch film 16 so that a part of the pallet 11, the tray 12, and the lowermost part 10 of the mat roll 13 are integrated. After winding 15 times, the winding part is directed upward from a predetermined point, and continuously in the longitudinal direction of the mat roll 13 until reaching a height T of 1300 mm from the lower end 13b of the mat roll 13. This is performed by winding the stretch film 16 spirally.

  The mat roll package 10 thus produced is stored for 6 months in the same environment as when a normal glass fiber mat is conveyed, and then whether both ends of the mat roll 13 are visually observed is deformed. When the shape of the part was investigated, no deformation was observed. Further, in order to release the mat roll 13 in the packed state, when the release operation is performed at a speed of 30 m / min while applying a constant tensile force to the mat roll 13 and the fiber mat is rewound, wrinkles are generated. In addition, the mat was not torn off, and it was found that excellent quality at the beginning of production without any problems was maintained.

  The fiber mat packing body and packing method of the present invention can also be applied to inorganic fiber mats other than glass fibers or organic fiber mats.
