Description

  The present invention relates to a packing method and a packing apparatus for a compressed object to be packed (contents in which a fiber assembly such as a thread, a tow, and a filament is compressed).

Fiber aggregates such as filaments, tows and filaments have a low bulk density. For example, a filter tow composed of cellulose acetate filaments has a small bulk density of about 100 kg / m 3 . Therefore, in order to improve transport efficiency and processability to tobacco filters, the bulk density is increased to about 300 to 600 kg / m 3 by compressing with a pressing means such as a press in the filament packing process, and then packed. Yes.

  On the other hand, the press pressure in the packing process is high, and the press compression pressure at the time of packing the filament reaches a maximum of 5000 kPa, and even if the compression pressure is low, it does not fall below 1000 kPa. For this reason, a repulsive internal pressure (expansion pressure) of about 20 kPa to 100 kPa remains in the filter tow packing body due to the stress repelling compression after packing. In order to make a packing body that can withstand such a high repulsive internal pressure, conventionally, the filter tow has been packed with a packing material (polyethylene film, polypropylene film, cardboard, interleaf, and a laminate thereof), and then a band (made of iron And a plastic band or the like, which are called bundling bands), and has a packing form in which the rebound internal pressure of the remaining filter tow is held by the bundling band. However, in this method, the binding band may bite into the compressed filter tow surface layer, and when the filter tow is opened, the tow or filament may break. In addition, there is a difference in the outer diameter size of the package, and hence the bulk density of the filter tow, between the binding part by the binding band and other parts, so that the weight of the tobacco filter rod manufactured using this filter tow varies. It affects the taste of tobacco. Furthermore, if the binding band is cut to unpack the package, not only will the cut binding band bounce off and the operator may be injured, but the packing material will be broken by the edge of the band, and the filter tow will be exposed. There is also a case.

  In view of such a problem, a packing form without a binding band has been studied. In DE 76-U35849 (Patent Document 1), a compressed filter tow is packaged with a packaging material, and the packaging material is bonded using the adhesive applied to the packaging material to form a package. Is disclosed. In this document, a compressed filter tow is wrapped with a laminate of polypropylene and paper vapor-deposited on the inside, and the outside is bonded with a solvent-type adhesive (specifically, a solvent-type adhesive of chloroprene rubber "Fastbond"). A package wrapped in cardboard is described.

  However, in the method described in this document, since a solvent-type adhesive is substantially used, the odor of the solvent adheres to the filter tow.

  Japanese Patent Application Laid-Open No. 7-215338 (Patent Document 2) discloses a technique for joining an upper part and a central part of a collection container using a hook-and-loop fastener tape without using an adhesive. However, this technology has several upright side parts that surround and demarcate the perimeter of the collection container, and these side parts can withstand repulsive internal pressure without a binding band. ing. That is, in the side portion of the package, a surface fastener is interposed between the side part and the collection container, and the surface fastener is always pressed and firmly bonded by the repulsive internal pressure of the collection container. For this reason, the side parts are required to have rigidity sufficient to withstand the repulsive internal pressure of the collection container, and the packaging form becomes large and the cost is increased. Therefore, this package cannot be applied to one-way packaging and can be used only within a range in which the packaging material can be collected and reused.

  Moreover, in order to give the strength of the bonding part that can withstand the internal pressure of the package body of a high rebound internal pressure, it is necessary to apply a considerably high pressure at the time of forming the package body. There is a problem that the contents are ejected from the package when compressed and packaged and a high pressure bonding force is applied to the bonding part.

In Japanese Patent Publication No. 9-508880 (Patent Document 3), a fibrous material, in particular, a press bale made of a cut fiber or a strand-like fiber, is applied to the periphery of the bale and fixed. In a method for packaging in a bale press using a plurality of shape elastic packaging material sections, a method is disclosed in which the packaging material sections are overlapped with each other and bonded together by adhesion or melting, and the press bale is packaged. . This document also describes a heat-sealing device provided with point-like or stripe-like punches for adhering or melting a packaging material section. However, according to the method described in this document, the bonding of the packaging material sections is performed by adhesion or melting, so that time is required for heating and melting, and the packaging speed and the productivity of the package cannot be improved.

An object of the present invention is to provide a packing method and a packing apparatus capable of packing while preventing.

  As a result of intensive studies to achieve the above-mentioned problems, the present inventors cause a time delay when using bonding by pressure-sensitive bonding means (adhesion with a pressure-sensitive adhesive or mechanical engagement with a surface fastener). Without being able to quickly join the packaging member, when the pressure-sensitive joining means is moved by the crimping means and crimped in a dotted or linear manner, a fiber aggregate (aggregate of filamentous bodies, tows, filaments, etc.) ) Is compressed and the packing member can be reliably and efficiently joined without causing separation due to the repulsive internal pressure even in a packaged body with a high rebound internal pressure (expansion force), and the present invention is completed. did.

  That is, in the method of the present invention, the compressed contents are packed in a packing container composed of a plurality of packing members having joint portions that can be brought into surface contact with each other, and the contents are accommodated.

Further, the holding portion that holds the rotation shaft and the guide may be coupled via a hinge. The pressure-bonding force of the pressure-bonding member may be 10 kPa or more, and the pressure-sensitive bonding means may be composed of a pressure-sensitive adhesive or a hook-and-loop fastener.

  The apparatus of the present invention includes a hollow cylinder whose bottom is closed by a shutter member, a supply unit for supplying a fiber assembly into the hollow cylinder in a state where the bottom is closed by a shutter member, and a shutter member from the bottom.

However, the bottom plate packing material and the top plate packing material that can be respectively attached to the pair of press plates and can enter the hollow cylinder as the press plate moves, and these bottom plate packing materials A pressure-sensitive bonding means for forming a bonding portion at a bonding portion extending in the circumferential direction of the top plate packing material, and a bonding portion that can be brought into surface contact with the bonding portion and can be bonded by pressure bonding With the side packing material, bottom plate packing material, top plate packing material, and side packing material in surface contact at the bonding site, the bonding site is crimped in a dotted or linear shape while moving the crimping member. A crimping unit (or a crimping device). Of the bottom plate packing material and the top plate packing material, at least one packing material that enters the hollow cylinder as the press plate moves can be slidably moved in an unbonded state with respect to the inner wall of the hollow cylinder. . Further, the bottom plate packing material and the top plate packing material are provided on the outer surfaces of the bottom plate and the top plate, a plurality of side pieces that can be bent from the bottom plate and the top plate, and a plurality of side pieces in a folded state. And a first pressure-sensitive joining means that is formed in a circumferential direction with a width and is slidably movable in a non-joined state with respect to the inner wall of the hollow cylindrical body. And a second pressure-sensitive joining means formed in a portion corresponding to the pressure-sensitive joining means in the lower portion, and the pressure-bonding unit (or pressure-bonding device) is provided on the second pressure-sensitive joining means. You may provide the roller provided with the rotating shaft for crimping | bonding a bonding site | part in the state which accumulated the 1 pressure-sensitive joining means. Further, the crimping unit includes a holding portion for rotatably holding both side portions of the rotating shaft of the roller, a guide for guiding the holding portion along the joint portion, and the holding portion and the guide.

Can be uniformly crimped with a predetermined crimping force. In addition, if the crimping member (crimping roller, etc.) can be swung (can be swung in a direction orthogonal to the bonding part) by hinge connection (pivot structure or pin connection), the bonding part depends on the shape of the package. Even if the distance between the crimping member and the crimping member varies depending on the location, the crimping member can follow the shape of the bonded portion.

Even if it is a to-be-packed body, it can package simply and efficiently, without using a binding band. Therefore, it is possible to effectively prevent problems in quality of the fiber aggregate (tow etc.) generated due to the binding band, for example, cutting or breaking of the tow. Further, since the pressure-sensitive joining means is joined by pressure bonding, the packaging body can be obtained smoothly and efficiently with a high packaging speed even if it is connected in-line with the production process of the filamentous body such as a filter tow. Furthermore, even a packaged body of a fiber assembly having a high repulsive internal pressure (or expansion force) can be packed while preventing the filamentous body such as a filter tow from being cut or broken without using a member having high rigidity. Furthermore, no application of an adhesive is required, no odor problem due to the solvent occurs, and deformation of the package and ejection of the contents do not occur.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a schematic diagram showing a fiber assembly accommodation or filling process, FIG. 2 is a schematic diagram showing a state before compression of the fiber assembly, FIG. 3 is a schematic diagram showing a state after compression of the fiber assembly, and FIG. FIG. 5 is a schematic diagram showing a process of extracting a hollow cylinder from a compressed fiber assembly, FIG. 5 is a schematic diagram showing an arrangement state of a bottom plate packing material, a top plate packing material and a side packing material, and FIG. 6 is a bottom plate packing. FIG. 7 is a schematic side view showing the main part of the crimping unit, FIG. 8 is a schematic perspective view showing the main part of the crimping unit, and FIG. FIG. 9 is a schematic side view showing the crimping unit.

  As shown in FIG. 1, the bottom of a hollow cylinder (can body) 1 having a square cross section with both ends opened can be opened and closed by a shutter member 2. In the accommodation process of the fiber assembly F, the fiber assembly F is supplied or filled into the hollow cylindrical body 1 with the bottom portion closed by the shutter member 2. In this example, a crimped filter tow having a predetermined width is conveyed by a pair of rollers 3 and is accommodated or filled in the hollow cylinder 1 while being folded by a transfer machine 4 traversing with a predetermined width. Yes. However, even if a bulky crimped filter tow is accommodated in the hollow cylinder 1, the storage or transport efficiency of the contents F is greatly reduced. Therefore, the crimped filter tow is compressed and packed.

  As shown in FIG. 2, in the compression process, the pair of press plates 5 and 6 for compressing the contents (in this example, the folded filter tow) F includes a bottom plate packing material 7 and a top plate packing, respectively. The material 8 is mounted, and at least one of the bottom plate packing material 7 and the top plate packing material 8 can move in the hollow cylindrical body 1 with the movement of the press plate 5b. Therefore, it is possible to compress a predetermined amount of the fiber assembly F accommodated in the hollow cylinder 1 with the shutter member 2 removed from the bottom. In this example, of the bottom plate packing material 7 and the top plate packing material 8, the top plate packing material 8 can enter the hollow cylinder 1 as the press plate 6 moves, and the inner wall of the hollow cylinder 1 Can slide or move in a non-bonded state. More specifically, the bottom plate packing material 7 and the top plate packing material 8 include a rectangular bottom plate 7a and a top plate 8a, and four side pieces 7b that can be bent from each side of the bottom plate and the top plate, 8b, and are formed in the circumferential direction with a predetermined width on the outer surfaces (the inner surfaces of the side pieces in the non-folded state) 7b, 8b of the four side pieces when folded outward. A first pressure-sensitive joining means 9 is provided which can slide or move in a non-joined state with respect to the inner wall of the hollow cylindrical body 1. In this example, the first pressure-sensitive bonding means 9 is composed of a pressure-sensitive adhesive, and this pressure-sensitive adhesive layer forms a bonding site. A release paper (or release paper) is affixed to the surface of the pressure-sensitive adhesive layer (the surface that can come into contact with the inner wall of the hollow cylinder 1) to prevent sticking to the inner wall of the hollow cylinder 1. is doing. Therefore, with the forward movement of the press plate 6 by the upper press, the top plate packing material 8 enters the hollow cylindrical body 1, and the fiber assembly F in the hollow cylindrical body 1 is formed as shown in FIG. Pressurized and compressed to form a bale.

  In the compression of the filter tow, the compressed bale is usually compressed to about 50 to 150 cm in length and width (for example, 70 to 140 cm, usually 90 to 130 cm) and about 50 to 120 cm in height (for example, 70 to 110 cm). (Contents) has a large mass of about 200 to 800 kg (for example, 300 to 600 kg).

  After the compression step, the hollow cylinder 1 is extracted from the compressed fiber assembly F. In this extraction process, as shown in FIG. 4, the hollow cylinder 1 is extracted by lifting or pulling the hollow cylinder 1 upward while the fiber assembly F is compressed by the pair of press plates 5 and 6. be able to.

  The compressed bale (compressed material) from which the hollow cylinder 1 is removed is packed with a packing material. That is, in the packing process, as shown in FIG. 5, in the compressed state, the opposing side portions of the compression bale (compressed material) F are U-shaped in cross section and partially at the side end portions. A pair of side wall members 10 and 11 that can overlap each other are disposed to constitute a side packing material. A second pressure sensitive joining means 12 is formed in a circumferential direction at a portion corresponding to the first pressure sensitive joining means 9 in the upper and lower portions of the side wall members 10 and 11. The second pressure-sensitive bonding means 12 is also composed of a pressure-sensitive adhesive like the first pressure-sensitive bonding means 9, and the adhesive layer composed of this adhesive forms a bonding site. . A release paper (or release paper) is attached to the surface of the pressure-sensitive adhesive layer.

  Therefore, after wrapping the side part of the compressed product (bale) F with the side part packing materials 10, 11, the outer surface of each side piece 7 b, 8 b of the bottom plate packing material 7 and the top plate packing material 8 (on the side in the non-turned state) The inner surface of the piece is folded to the side packing materials 10 and 11 side, and the first pressure-sensitive bonding means is placed on the second pressure-sensitive bonding means (adhesive layer) 12 as shown in FIGS. In the state where the (adhesive layer) 9 is overlapped, a packing body can be formed by crimping the bonding site in the crimping step using the crimping unit. That is, with the bottom plate packing material 7 and the top plate packing material 8 and the side packing materials 10 and 11 being in surface contact with each other at the bonding site, the bonding site is crimped while moving the crimping member of the crimping unit, and the packaging is performed. Forming the body.

  As shown in FIGS. 7 and 8, the pressure-bonding unit rotatably holds a rotatable roller (pressure-bonding roller) 15 for pressure-bonding the bonded portion and both sides of the rotating shaft of the roller. A holding part 16 for pivoting, a pivoting member 17 for pivotably pivoting the holding part (or the roller 15) by a pivot (hinge coupling or pin coupling) 18, and the joining part (bonding part) ) And a guide member 19 for guiding the holding portion 16 along the joining portion (bonding site), and between the holding portion 16 and the pivot member 17. And an intervening spring 20.

  The guide member 19 can travel on the rail portion of the frame 21. That is, a roller 22 is rotatably attached to the guide member 19, and this roller is accommodated in a guide portion (guide rail) 23 of the frame 21 so as to be able to run. The crimping units having such a structure are respectively formed on the upper and lower portions of the frame 21 corresponding to the bonded portions of the bottom plate packing material 7 and the top plate packing material 8 and the side packing materials 10 and 11. In addition, crimping | compression-bonding operation is each performed by four side surfaces of the said package by moving in the horizontal direction, pressing the roll 15 with respect to the surface of the bonding site | part of a packaging material.

  In such an apparatus and method, the pressure sensitive adhesives 9 and 12 are used by bringing the roller 15 into line contact with the bonding portion and pressing the bonding portion in a line while moving the bonding portion with a predetermined pressure. Since it can join rapidly, the packing time of fiber assemblies F, such as a filter tow, is not delayed. That is, in the method of packing a fiber assembly F such as a filter tow without a binding band, the main rate-limiting process in the packing process is an operation process of attaching a packing material to the fiber assembly F such as a compressed filter tow. More specifically, if an adhesive is applied during the packing operation, it takes time to apply the adhesive, and the packing operation time becomes longer, which increases the production speed of the fiber assembly F such as filter tow that is performed at high speed. The packing operation cannot catch up, and the production amount of the fiber assembly F such as filter tow has to be reduced. On the other hand, when the pressure-sensitive adhesives 9 and 12 are used, it is not necessary to apply an adhesive and work efficiency can be improved.

  Further, the fiber assembly F such as the filter tow can be efficiently packed by crimping the bonded portion so as to exhibit the shear strength equal to or higher than the repulsive internal pressure (or expansion force) of the fiber assembly F such as the filter tow. That is, the bonding strength of the pressure-sensitive adhesives 9 and 12 has a characteristic that changes depending on the pressure-bonding force, and when the pressure applied to the bonding portion is increased in order to increase the peeling strength of the bonding portion, the deformation and contents of the packaging body A jet of things occurs. On the other hand, when the roller 15 is pressure-bonded, the bonding part and the roller 15 are in line contact with each other, so that a high pressure can be applied to the bonding part without applying a very high pressure to the entire package. . Therefore, while preventing deformation of the packing body and ejection of contents, the packing material can be securely and firmly joined at the bonding site, and the rebound internal pressure (or expansion) of the fiber assembly (compression bale) F such as compressed filter tow It can be packed with shear strength (adhesive strength) that can withstand force. In addition, since the roller 15 can swing, the pressure can be effectively applied to the bonding site by following the uneven shape, and the packing material can be bonded efficiently and firmly at the bonding site. Further, by moving the roll 15 in the horizontal direction within the frame 21 with respect to the surface of the packing material, it can be joined by a crimping unit having a simple structure.

  Furthermore, the problem of tow quality caused by the binding band does not occur. That is, when (compression bale) F such as a tobacco filter tow of cellulose acetate is packed using a binding band, the binding band bites into the compression bale F, and the crimped tow and filament are damaged at the fastening portion. Therefore, when the packed compression bale F is opened to prepare a filter rod, the tow or filament is broken or cut. However, when the apparatus and method of the present invention are used, the compressed bale can be opened smoothly and the filter rod can be manufactured efficiently.

  In addition, in the apparatus and method of the present invention, cutting or breaking a filamentous body such as a filter tow without using a member having a large rigidity even in a packaged body of a fiber assembly having a high repulsive internal pressure (or expansion force). Can be packed while preventing. Furthermore, no application of an adhesive is required, no odor problem due to the solvent occurs, and deformation of the package and ejection of the contents do not occur.

The apparatus and method of the present invention is useful for packing compressed contents without using a tie band. In this invention, a package can be hold | maintained, without using a highly rigid side part. The compressed content is not particularly limited as long as it has a repulsive internal pressure (or expansion force), particularly a high repulsive internal pressure (or expansion force), but the fibrous content is required to be compressed to a compact volume with a small bulk density. To be packed, for example, made of filamentous material (filament, strand, tow or tow band, especially filter tow, etc.) composed of organic or inorganic fibers, especially cellulose acetate fibers, etc. This is advantageous for packing of the contents to be compressed and packed by the pressure means. Packing such contents can reduce storage and transportation space and improve handling. The bulk density of the compressed fiber aggregate (packed fiber aggregate) is about 200 to 800 kg / m 3 , and is usually about 300 to 600 kg / m 3 (for example, 350 to 550 kg / m 3 ). Moreover, the repulsion internal pressure is about 20-100 kPa, and is usually about 25-75 kPa (for example, 30-50 kPa).

  In the formation of the packing body of the present invention, the compressed contents (such as fiber aggregates) F may be packed, and the contents (such as fiber aggregates) F may be stored or filled, and the contents (such as fiber aggregates). ) The step of compressing F, the step of extracting the hollow cylinder from the compressed contents (fiber assembly, etc.) are not necessarily required. In addition, the content (fiber assembly etc.) F can be efficiently packed through the said process.

  In the process of containing or filling the contents (fiber assembly etc.), the bottom of the hollow cylinder need not be openable / closable by an opening / closing member such as a shutter member, and if the cylinder constitutes a packing material, the cylinder The bottom of may be closed. If a hollow cylinder whose bottom is openable and closable by a shutter member is used, the contents (such as fiber aggregates) are accommodated or filled, and then conveyed to a compression site equipped with a press machine by a conveyance line and to the compression site. Extraction of the shutter member from the conveyed cylinder and compression of the contents at the compression site can be sequentially performed, and packing efficiency can be improved. Moreover, one hollow cylinder can be repeatedly used by extracting a hollow cylinder from the content after compression. The hollow cylinder is usually formed as a pressure-resistant hollow cylinder in order to have durability against stress generated by the compression of the contents (such as a fiber assembly). The cross-sectional shape of the hollow cylinder is not limited to the rectangular shape, but may be a polygonal shape, a circular shape, an elliptical shape, or the like.

  Various supply devices (or supply units) can be used to store or fill the contents (such as fiber aggregates) in the hollow cylinder, and for example, the traverse device, conveyor, and conveyance roller may be used. The contents may be accommodated or filled into the hollow cylinder by manual operation.

  In the compression step, when the hollow cylinder is used, a predetermined amount of contents or contents (such as a fiber assembly) accommodated in the hollow cylinder is compressed with the shutter member removed from the bottom. It is advantageous. Various compressing or compressing devices can be used for compressing the contents. Usually, a pressurizing or compressing device including a pair of pressurizing units (such as a press plate) that can move forward and backward relative to each other is used. . In such an apparatus, the pressurizing unit may be composed of a cylinder (air cylinder, hydraulic cylinder, etc.) that can move forward and backward, and is composed of a cylinder that can move forward and backward and a press plate attached to the cylinder. May be. Usually, the pressure unit is often provided with a press plate that can be moved back and forth by a cylinder. In a pressure unit equipped with a press plate, both press plates may be movable back and forth, but usually one press plate (the upper press plate in the above example) is the other press plate (in the above example). It only needs to be able to move forward and backward relative to the lower press plate.

  In the extraction step, in order to extract the hollow cylinder 1 from the compressed content (fiber assembly or the like), various extraction units, for example, a traction device that pulls the hollow cylinder can be used. In addition, for extracting compressed contents (such as fiber aggregates), not only the method of extracting the hollow cylinder upward, but also a method of extracting downward may be used, and the side wall of the hollow cylinder can be opened and closed. An open / close method (such as a hinge-type open / close method) may be used. In addition, extraction of a hollow cylinder is performed in the state which compressed the contents (fiber assembly etc.).

  In the present invention, in order to tightly pack the contents (such as fiber aggregates) in the packing container, it is only necessary to have a packing process (or packing apparatus) for packing the compressed contents with a packing material. May be provided with at least a crimping unit (or crimping device).

  In the present invention, the packing container can be composed of a plurality of packing members, and the adjacent packing members are usually firmly bonded by pressure-sensitive bonding means (pressure-sensitive bonding elements), and therefore have bonding portions that can be brought into surface contact with each other. Each of these joints is provided with a pressure-sensitive joining means (pressure-sensitive joining element) to form a bonding site. A package is obtained by wrapping the compressed contents with a plurality of packaging materials having these bonding parts, and bonding the bonding parts to each other for packaging.

  A packing container can be normally comprised by the baseplate packing material which comprises a bottom part, the top plate packaging material which comprises an upper part, and the side part packaging material which comprises a side part. The bottom plate packing material, the top plate packing material, and the side packing material may be bonded to each other at the bonding portion formed by extending in the circumferential direction by pressure-sensitive bonding means at the bonding portion of each packing material. The bonding means (pressure-sensitive bonding element) may be provided on at least one of the bottom plate packing material, the top plate packing material, and the side packing material, and the bottom plate packing material, the top plate packing material, and the side It is preferable to provide both on the part packing material.

  In order to increase packing efficiency, as described above, it is preferable that the bottom plate packing material and the top plate packing material can be respectively attached to a pair of pressure units (such as a press plate). The bottom plate packing material and the top plate packing material do not necessarily require the side piece, but in order to increase the bonding strength with the side packing material, the side plate, particularly the bottom plate and the top plate, respectively outward (radial direction) It is preferable to have a plurality of side pieces (a plurality of side pieces that can be bent). In particular, when the bottom plate and the top plate are polygonal, it is preferable that a plurality of side pieces that can be bent extend from each side of the bottom plate and the top plate.

  The side packing material may be in surface contact with the joint between the bottom plate packing material and the top plate packing material, and may have a bonding part that can be bonded by pressure bonding. You may comprise with one side wall member to comprise, and may comprise with the some side wall member divided | segmented into the vertical direction and / or the horizontal direction. From the viewpoint of packing workability, as in the above example, the side packing material can be bent or bent in the lateral direction, and can be partially overlapped with each other on the side portions adjacent to each other. It is preferable to comprise a side wall member (for example, a pair of side wall members that can be bent into a U-shaped cross section). Moreover, the site | part corresponding to the junction part of the said bottom-plate packing material and a top-plate packing material among the upper part and the lower part of the outer surface of a side part packing material forms a junction part.

  The packing material may be various materials that can withstand the expansion force of the compressed content depending on the content and the expansion force thereof, such as paper, interleaf made of a plurality of papers, cardboard, woven fabric, Nonwoven fabrics (for example, polyethylene fabrics), composite sheets thereof (for example, laminated sheets of paper and plastic, laminated sheets of woven fabric and plastic, etc.) can be used.

  The bottom plate packing material, the top plate packing material, and the side packing material may be bonded to each other by pressure-sensitive bonding means (pressure-sensitive bonding element) at the joint, and the upper and lower packing materials (bottom plate packing material and top plate packing). Material) and at least one of the side packaging materials may be provided with pressure-sensitive joining means (pressure-sensitive joining element) to form a bonding site. In a preferred embodiment, pressure-sensitive joining means (pressure-sensitive joining elements) are provided at the joints of both the upper and lower packing materials (the bottom plate packing material and the top plate packing material) and the side packing materials, and the bonding site is It is formed. That is, the bottom plate packing material and the top plate packing material (especially each side piece) are formed with the first pressure-sensitive bonding means (pressure-sensitive bonding element) with a predetermined width in order to form a bonding portion with the side packing material. ) Is formed, and second pressure-sensitive joining means is formed at a portion (joining portion) corresponding to the pressure-sensitive joining means among the upper and lower portions of the outer surface of the side wall member. In addition, in the bonding of the bottom plate packing material and the top plate packing material (particularly each side piece) and the side packing material, the first pressure sensitive bonding means is stacked on the second pressure sensitive bonding means. The bonding part may be pressure-bonded, and conversely, the bonding part may be pressure-bonded in a state where the second pressure-sensitive bonding means is stacked on the first pressure-sensitive bonding means.

  As the contents are compressed (for example, the forward movement of the press plate), at least one of the bottom plate packing material and the top plate packing material can move (enter) the hollow cylinder 1. Is preferred. In this case, it is preferable that the inside of the hollow cylinder 1 can be moved (invaded) in a state where the pressure-sensitive joining means is attached to the side piece of the bottom plate packing material and the top plate packing material. Further, the pressure-sensitive joining means may be attached to either the inner surface or the outer surface of the side piece of the bottom plate packing material and the top plate packing material, and the surface of the side piece in a non-contact state with the inner wall of the hollow cylindrical body 1 ( When pressure-sensitive joining means is provided on the inner surface, the hollow cylinder 1 can be moved or infiltrated smoothly. On the other hand, when the pressure sensitive joining means is formed on the outer surface of the plurality of side pieces in the state where the side pieces of the bottom plate packing material and the top plate packing material are folded outward as in the above example, pressurization or contents The pressure-sensitive joining means is in pressure contact with the inner wall of the hollow cylinder 1 by the expansion force. Therefore, as the contents are compressed by the pressure unit, the ingress of the packing material attached to the pressure unit that moves forward among the bottom plate packing material and the top plate packing material is restricted or the pressure-sensitive joining means is damaged. There is a case. In such a case, like pressure sensitive adhesive layer release paper, the pressure sensitive joining means is covered with a protective sheet or the like, and can be slid or moved in a non-joined state with respect to the inner wall of the hollow cylinder 1. Is preferred.

  The packaging member forms a bonding site by pressure-sensitive bonding means (or a pressure-sensitive bonding element or component) of a bonding portion (particularly, a bonding portion extending in the circumferential direction with a predetermined width). The pressure-sensitive joining means can be composed of various materials and members that exhibit bonding or adhesive strength by pressurization, and can usually be composed of a pressure-sensitive adhesive or a hook-and-loop fastener (physical coupling component).

  The pressure-sensitive bonding means is not particularly limited as long as the pressure-sensitive bonding means expresses adhesive strength by a pressure-bonding force, and a pressure-sensitive adhesive is suitable. Moreover, a surface fastener can also be used suitably as a pressure-sensitive joining means. Examples of pressure-sensitive adhesives include various pressure-sensitive adhesives such as diene rubbers such as nitrile rubber, butyl rubber, and isoprene rubber, styrene-butadiene rubber, block copolymers (styrene-butadiene-styrene block copolymers, styrene-isoprene). -Styrene block copolymers, hydrogenated block copolymers thereof, ethylene-vinyl acetate copolymers, (meth) acrylic polymers (acrylic such as ethyl acrylate, butyl acrylate, 2-ethylhexyl acrylate) Examples thereof include (meth) acrylic polymers using acid alkyl esters and the like. These adhesives can be used alone or in combination of two or more.

The pressure sensitive adhesive may contain a tackifier (tackifier). The tackifier (tackifier), hydrocarbon resins, for example, rosin ester, coumarone - indene resin, alpha-methylstyrene - vinyl toluene copolymer, C 5 fraction, C 9 fraction of the polymer (petroleum resin ), Dicyclopentadiene resin, terpene resin and the like, and the tackifier (tackifier) may be hydrogenated. The proportion of tackifier (tackifier) is 1 to 150 parts by weight, preferably 3 to 100 parts by weight, more preferably about 5 to 80 parts by weight, based on 100 parts by weight of the pressure-sensitive adhesive, in terms of solid content. There may be. Note that the pressure-sensitive adhesive may contain a stabilizer (such as an antioxidant or an ultraviolet absorber).

The hook-and-loop fastener can be composed of a loop-type female member and a hook (or anchor) -type male member, and an anchor type can be suitably used as the male member. The density of the hook is, for example, 10 × 10 4 to 100 × 10 4 pieces / m 2 , preferably 20 × 10 4 to 90 × 10 4 pieces / m 2 (for example, 40 × 10 4 to 80 × 10 4 pieces / m 2 It may be about m 2 ). Moreover, the length of a hook may be 1-5 mm (for example, 1.2-3 mm), for example, Preferably about 1.5-2.5 mm may be sufficient as it.

  Incidentally, the moisture absorption / rehumidification type and thermosetting type (two-component type) adhesives cause problems of odors such as solvents and reactive monomers. Therefore, in the method of laminating the packing material, the pressure sensitive adhesive that does not contain solvent or reactive monomer is used, and the physical bonding parts such as the pressure sensitive adhesive application part and the hook-and-loop fastener are pressed to paste the packing material. It is preferable to combine them. In particular, in the packing of a packaged object such as a filter tow, a bonding member exhibiting a strong adhesive strength sufficient to overcome a high repulsive internal pressure (expansion force), especially a physical material such as a pressure-sensitive adhesive or a hook-and-loop fastener. It is preferable to use a simple coupling component.

  Such bonding members (physical bonding parts such as pressure-sensitive adhesives and hook-and-loop fasteners) are already known, but in order to develop the bonding strength of the bonding members, it is necessary to apply a high pressure bonding force. That is, when a packaged body having a high repulsive internal pressure, such as a filter tow package, is packed by pressure bonding of a physical coupling member such as a pressure-sensitive adhesive or surface fastener, the pressure-sensitive adhesive or surface fastener is It was thought that the pasting part of the physical bonding parts could not withstand and the packing form could not be maintained. However, the packing material of the packed object such as the filter tow is composed of paper, interleaf paper, a woven composite sheet, etc., and the rigidity and strength of the packing material itself are not so high. Therefore, when a large pressure bonding force is applied, the package is deformed. Furthermore, since the package itself has a repulsive internal pressure (expansion force) due to the compressed package body such as filter tow, when external pressure is applied to the package body, the internal pressure acting on other parts of the package body Becomes larger and packaging defects such as ejection of contents from the package and rupture of other joints are likely to occur. More specifically, it is difficult to press the bonded portion using a smooth surface such as a press plate. That is, for pressure bonding of physical bonding parts such as a pressure-sensitive adhesive application part and a hook-and-loop fastener, it is necessary to apply a certain pressure or more to the bonding portion so as to exhibit a shear strength that is higher than the repulsive internal pressure of the filter tow. . In particular, pressure-sensitive adhesives require a pressing force far exceeding 400 kPa in order to obtain the required shear strength. If the pressing force is insufficient, a part having a low shear strength is generated at the bonding site. However, it can not withstand the repulsive internal pressure of the filter tow and peels off. And since the area of a bonding part is large (for example, it is 10 cm x 100 cm or more), when a pressure sensitive adhesive that requires a pressure of 400 kPa or more is used, it is necessary to press one bonding surface with a force of 4 Tf or more. And the size of the crimping device increases. Moreover, since the compressed filter tow is pressed by the upper and lower pedestals (upper and lower press plates) and a repulsive force of 2 to 40 Tf is generated, it is necessary to make the pressure of the bonded portion larger than this repulsive force. There is a possibility that such a defect may occur that the filter tow is pushed out of the pedestal on which the filter tow is placed and falls, the contents are ejected from the package, or the other joints are ruptured. However, if the bonding portions are bonded together while being locally pressed, the packaging material can be bonded securely and firmly.

  In the present invention, in a state where the contents are accommodated (compressed state), the bonded portion is crimped in a dotted or linear manner while moving the crimping member to form a packing container. That is, the apparatus of the present invention includes a crimping unit that includes a crimping member that is movable along the joining portion and that can be crimped to the bonding site by point contact or line contact.

  The crimping member may be crimped by surface contact if the contact area is small with respect to the bonding site (or joint), but a large pressure does not act on the entire package, and the bonding site. In order to apply a large pressure to (or the joint), it is preferable that the pressure can be applied by contact in a point or line form (point contact or line contact). That is, the peel strength at the bonding site by pressure-sensitive bonding means such as a pressure sensitive adhesive or hook-and-loop fastener has a characteristic that depends on the pressure bonding force. To increase the peel strength at the bonding site, When a high pressure is applied, the package is deformed or the contents are ejected. However, when a high pressure is applied to a dotted or linear narrow area, the pressure applied to the entire package is not so high, and the package is not deformed or the contents are not ejected. Therefore, in this invention, a crimping | compression-bonding member is made to contact locally (dotted or linear) with respect to a bonding site | part, it is crimped | bonded while moving a bonding site | part, and a bonding site | part is bonded.

  When pressure bonding by point contact or line contact is used, not only the force applied is smaller than that by surface pressure bonding, but also the surface unevenness of the portion to be bonded is easily followed. That is, as described above, in the cubic package, the surface of the bonded portion is not completely smooth, and there are minute uneven portions, curved portions, and the like. For this reason, even if it is brought into surface contact with a press plate or the like, it cannot follow the unevenness of the surface of the bonding part, but if point contact or line contact is used, the bonding force is appropriately applied all over the bonding part along the uneven part. High bonding strength can be obtained even with a small pressure.

  In addition, for example, a method in which the bonding part is crimped over the entire surface using a material having a flexible surface, or a uniform crimping force may be applied to the bonding part with a flexible tubular body filled with gas or liquid. Conceivable. However, in these methods, there is a limit to the followability to the concavo-convex portion on the surface of the bonded portion. In addition, since the crimping surface is large, when the crimping force is increased, the stress applied to the entire bonded portion is considerably increased, and as described above, the package is easily deformed or the contents are ejected.

  In this invention, the contact surface of the pressure application part of a crimping | compression-bonding member should just be crimpable with respect to a bonding site | part, and does not need to be substantially parallel to the surface of a bonding site | part. In a preferred aspect of the present invention, the crimping unit is usually provided with a guide member disposed along the joint (or a bonding site) and a crimping member movable along the guide member. The member can apply a pressure equal to or greater than a predetermined value to the contact portion with the bonding site. The joint portion (or the bonding portion) and the guide member may be substantially parallel. In addition, the pressure-bonding member having the pressure application unit may be movable within the range of the bonding portion, and the pressure-bonding member may be movable along the guide member, and the pressure-bonding member is movable along the guide member. It may be fixed by a holding member or the like. Furthermore, the crimping member may be rotatable around the axis about the axis, and the axis of the crimping member may be supported so as to be rotatable.

  The crimping member may be composed of, for example, a spherical rotating body, but is usually composed of a roller having a rotating shaft. The peripheral surface of this roller may be smooth, and a pressure application section capable of point contact or line contact may be formed as described above. Normally, both sides of the rotating shaft of such a roller are held by holding parts so that the roller can rotate. The form of this holding part is not particularly limited. Moreover, a holding | maintenance part is guided along a junction part (bonding site | part) with a guide member. This guide mechanism is composed of a conventional element, for example, a rotation roller (guide roller) rotatably attached to the holding portion, and a guide portion (guide rail, storage portion, etc.) that guides the rotation roller rotatably. The guide portion may be formed on an exterior frame (frame or the like) of the crimping unit.

  Furthermore, it is preferable that an elastic body or a cushion member (a member having a buffer property and capable of pressurizing the pressure-bonding member against the bonding portion) is interposed between the holding portion and the guide. This elastic body or cushion member can be constituted by a spring (such as a metal spring) or an air shock (air cushion). By disposing the elastic body or the cushion member, it is possible to suppress the fluctuation of the applied pressure with respect to the bonding site and to uniformly press the bonding site.

  FIG. 10 is a schematic view showing another example of a crimping unit (crimping device). In addition, the same code | symbol is attached | subjected and demonstrated about the member similar to the said crimping | compression-bonding unit (crimping apparatus). In this example, a cylinder 30 is provided instead of the spring 20. That is, the pressure-bonding unit (pressure-bonding device) includes a holding member 16 that rotatably holds the rotation shaft of the pressure-bonding roller 15, a pivoting member 17 that pivotally supports the holding member by a pivot 18, A plurality of cylinders 30 for pressing the pivot member at a plurality of locations in the longitudinal direction, a guide member 19 to which these cylinders are attached and guiding the holding member 16 along the guide, and the guide member And a frame 21 for holding the frame. The cylinder body 30 a of the cylinder 30 is attached to the guide member 19, and the rod 30 b that can be moved forward and backward is attached to the pivot member 17. In this example, the rod 30 b of the cylinder 30 is attached to both side portions that are spaced apart from the central portion in the longitudinal direction of the pivot member 17. The cylinder body 30a is filled with a gas pressurized at a predetermined pressure, and the rod 30b forms an air cushion that can move forward and backward according to pressure fluctuations. Further, guide rollers 22 are rotatably attached to both upper and lower ends of the guide member 19, and the guide rollers are accommodated in a guide portion (guide rail) 23 of the frame 21.

  Even with such a crimping device, the cylinder can suppress fluctuations in the applied pressure to the bonding site, and the bonding site can be uniformly crimped, and the spacing between the packing material surface and the crimping roll due to warpage or partial unevenness of the packing body Even if it fluctuates depending on the location, because of the pivot structure, the crimping roll can swing in a direction perpendicular to the axis of the rotating shaft, Can be moved.

  In the above example, a cylinder constituting a liquid cushion may be used instead of the air cushion. Moreover, although the moving direction of the crimping member and the axial center direction of the rotating shaft of the crimping member are orthogonal, the moving direction of the crimping member and the axial center direction of the rotating shaft of the crimping member may be the same direction.

  The pivoting member is not necessarily required to make the crimping member swingable, and the holding portion or the holding member that holds the shaft of the rotating body (rotating roll or crimping roll) and the guide member have a pivotal structure ( They may be connected by a hinge connection (pin connection or pivot structure) connected via a hinge.

  The pivot attachment structure (or hinge connection) may be any connection unit (coupling device) that can be varied (stretched or swung) along an axis orthogonal to the bonding site (bonding surface). If present, the elastic body may be arranged on the pivot structure (or hinge connection), and the crimping force may be set to a desired value.

  The guide member may be smoothly moved along the guide portion by using a lubrication mechanism (or a rolling mechanism) such as a roll or a bare link for guiding the pressure-bonding member (pressure-bonding roll or the like) by the guide member. In addition, the guide member may be moved manually, and mechanically operated using a reciprocating mechanism using rotational movement by gears, gears, chains, motors, etc., advancing / retreating mechanism by cylinder pressure, etc. Also good.

  In the pressure-bonding member, the number of point-like or line-like pressure application units for making point contact or line contact is not particularly limited, and may be one or plural. Moreover, the dotted | punctate or linear pressure application part may be scattered regularly or irregularly. In addition, point contact or line contact may be performed in a certain area as long as the stress does not cause deformation of the package and ejection of contents. The shape of the pressure application portion of the pressure-bonding member for point contact may be, for example, a polygonal truncated cone shape such as a truncated cone shape or a triangular truncated cone shape. The pressure application units for point contact may be scattered on the circumferential surface of the cylindrical body (roll or the like), and may be regularly arranged in the circumferential direction and / or the axial direction. For example, the pressure application unit for point contact is a line extending in the circumferential direction of a cylindrical body (such as a roll) (a straight line extending in a direction perpendicular to or intersecting the axial direction, a direction extending in a direction intersecting with the axis direction, or regular or indefinite to the axial direction It may be formed in a curved line (S-shaped curve or the like) or meandering line extending in a meandering manner or in a staggered pattern. In addition, when the crimping member is a cylindrical body (such as a roll), it can be in line contact with the bonding site without forming a convex portion in particular, but it is in line contact with the peripheral surface of the cylindrical body (such as a roll). The pressure application part may be formed. The pressure application unit for line contact can be constituted by a ridge formed in the circumferential direction of a cylindrical body (roll or the like), and this ridge may be linear or curved or bent at a predetermined cycle. May be. In addition, the pressure application unit for line contact may be constituted by a plurality of ridges extending in the circumferential direction at a predetermined interval in the axial direction of the cylindrical body (roll or the like), and intersect with each other in the form of a lattice or the like. And you may comprise by the some protruding item | line extended in the circumferential direction. The cross-sectional shape of these ridges may be a quadrangular pyramid shape. Furthermore, a pressure application unit capable of point contact and a pressure application unit capable of line contact may be combined.

  FIG. 11 is a schematic perspective view showing another example of the pressure application section of the crimping member. In this example, a quadrangular pyramid-shaped convex portion 25a is regularly formed in the vertical and horizontal directions on the peripheral surface of the cylindrical pressure roller 25 to form a pressure applying portion. In the pressure-bonding unit provided with such a pressure-bonding roller 25, the bonding portion can be pressure-bonded with a high pressure by the convex portion 25a as the pressure-bonding roller rotates.

  FIG. 12 is a schematic perspective view showing still another example of the pressure application section of the crimping member. In this example, in the circumferential direction of the cylindrical pressure roller 35, a ridge 35a curved in an S shape with a predetermined period is formed to form a pressure application section. When such a pressure roller 35 is used, the bonded portion can be crimped into an S shape as the pressure roller 35 rotates.

  In addition, the bonding site | part (or package) and a crimping | compression-bonding member should just be relatively movable, and a crimping | compression-bonding member does not necessarily need to move. In addition, in order to prevent damage to the surface of the packing material and to improve the slipperiness of the crimping member, the surface of the crimping member is covered with a slidable member (such as a fluororesin member) or a highly slidable resin ( It may be coated with a fluororesin or the like, or may be bonded with a protective member (for example, a polypropylene resin sheet, a fluororesin sheet, etc.) interposed between the pressure-bonding member and the bonding site.

  The pressure-bonding force by the pressure-bonding member can be selected according to the degree of compression of the packaged body, the rebound internal pressure, the type of packing material, etc., and in the case of a fiber assembly, usually 10 kPa or more (for example, about 30 to 1500 kPa), preferably Is 50 kPa or more (for example, about 70 to 1200 kPa), more preferably 100 kPa or more (for example, 150 to 1000 kPa). Furthermore, in the case of a fiber assembly such as a filter tow, the crimping force by the crimping member is usually 50 kPa or more (for example, 75 to 800 kPa), preferably about 80 kPa or more (for example, 100 to 700 kPa). Depending on the type of aggregate, it may be 200 kPa or more (for example, about 250 to 800 kPa), preferably 350 kPa or more (for example, about 400 to 700 kPa), particularly about 400 to 600 kPa. The pressure-bonding force may be about 200 to 1000 kPa (for example, 300 to 800 kPa, preferably 350 to 600 kPa) when a pressure-sensitive adhesive is used, and 10 to 600 kPa (for example, when a surface fastener is used) 50 to 500 kPa, preferably 75 to 300 kPa).

  The present invention relates to the contents to be compressed and packed, in particular, fibrous aggregates [filamentous bodies (tows, filaments, strands, etc.) composed of fibers such as cellulose acetate], in particular, a filter in which a plurality of filaments are bundled Tow etc.] and can be used effectively for compressing and packing the contents by pressurizing means such as a press.

  Hereinafter, the present invention will be described in more detail based on examples, but the present invention is not limited to these examples.
