Description

  The present invention temporarily collects and collects a part or all of a tile carpet that has been applied and used and peeled off from an appropriate floor base under the control of the user or owner from the user of the tile carpet, and the carpet layer on the surface. In addition to providing a recycled tile carpet that is renewed and regenerated to a new carpet tile, the recycled tile carpet is constructed at a new location or returned to its original construction position and re-used.

  More specifically, in the present invention, the carpet layer obtained by peeling off the backing layer from the tile carpet that has been applied and in use is joined together by an appropriate method, and the soiled portion is removed by washing to remove the dirt layer. Alternatively, a wide and long carpet layer is formed, and the used tile carpet or the wide and long carpet layer surface and an unused carpet raw fabric are bonded together by an appropriate method, and cut into a predetermined size. The present invention relates to a tile carpet regeneration and reuse system that recycles and reuses tile carpets that have been installed and in use by forming recycled tile carpets together.

  Ten years have passed since tile carpets were widely used, and the time has come for renewal. On the other hand, the disposal of waste has become difficult year by year, and in particular, vinyl chloride resin-based products are accompanied by the problem of dioxins, and the disposal is even more difficult. It has become to.

  In the US, etc., after cleaning, the carpet layer on the surface is re-stained, patterned, and reused. However, once the soiled carpet layer is difficult to remove, it is difficult to remove the stain, and the dyeing color is inevitably dark. The fact is that it is limited to.

  As a technique for reusing tile carpets, there are techniques described in Patent Documents 1, 2, and 7. In these techniques, a surface decorative resin layer is formed on the front surface or the back surface of the waste material obtained by substantially cutting and removing the carpet layer. The reason why the carpet layer is substantially cut and removed is that when the carpet layer exists, an adhesive or a pressure-sensitive adhesive cannot be applied to the surface. Therefore, in these techniques, it was necessary to substantially cut the carpet layer. However, as a result, there is a problem that a large amount of fiber waste of the carpet layer is generated, which becomes industrial waste, and a carpet layer mowing process is required, leading to an increase in cost.

  In addition, a method of finely pulverizing the recovered tile carpet described in Patent Documents 3 to 5 and separating the carpet layer and the vinyl chloride backing layer by a specific gravity separation method or the like is generally performed. It takes a lot of energy to pulverize, and the noise during pulverization is large.

  These Patent Documents 1 to 5 are all based on the idea of reusing only the vinyl chloride backing material, which is half of the components of the tile carpet, and the carpet layer occupying the other half is again discarded as industrial waste. The technical idea to do so was at the root.

  Furthermore, Patent Document 6 proposes to make a tile carpet using a backing layer that can be easily pulverized by freezing to minus 30 ° C. or lower. However, the soft vinyl chloride already on the market is used as the backing layer. Since it is necessary to make the freezing temperature extremely low for application to the tile carpet, it has not been put into practical use.

JP 2000-220281 A JP 2000-220282 A Japanese Utility Model Publication No.59-132581 first page Japanese Utility Model Publication No.59-132582, first page JP-A-8-312117, page 2, paragraph 0005 JP-A-9-173197, page 3, paragraph 0018 JP 2003-236957 A

  On the other hand, the law on waste and cleaning is becoming more restrictive year by year, and handling industrial waste requires qualification and certification as a company and an individual for collection / transportation and disposal. However, it is a big burden for the tile carpet contractor who is the most to do it legally.

  In the past, tile carpet renewal was not subject to legal restrictions, and could be operated freely with the agreement of the user and the installer. On the other hand, it is undeniable that some contractors have been conscious of outsourcing used tile carpets to cheap waste disposal companies, resulting in illegal disposal.

  However, current regulations on waste and cleaning in order to screen some contractors, all tile carpet contractors will replace used tile carpets at all tile carpet renewal sites if legally attempted. Taking out and transporting them is not legal without a qualification and a processing contract with the prime contractor, and this is a great burden for a good contractor who intends to legally carry out fine renewal work.

  Based on the purpose of the law, the present inventors greatly reduce industrial waste derived from tile carpets, and at the same time, recycle and reuse resources, and good contractors who want to legally carry out fine renewal work. The present inventors have arrived at the present invention in order to devise a technology that can simultaneously reduce the burden on the owner or user of a building that bears industrial waste disposal costs.

  The object of the present invention is to propose a method of renewing only the carpet layer on the surface while keeping the ownership of the building owner or user without making the used and used tile carpet as industrial waste as much as possible. It is.

  In other words, all the tile carpet contractors need to remove the used tile carpet from the designated construction site and transport it from the building owner or user to the designated location without requiring a new relevant qualification. Accordingly, the carpet layers obtained through the thickness reduction step are joined to form a wide and long carpet layer, and the wide and long carpet layer surface and the unused carpet raw fabric are bonded together by an appropriate method. To establish a mechanism that allows the regenerated tile carpet to be transported again and reconstructed at the same location or a new location after undergoing the process of forming a recycled tile carpet by trimming to a predetermined size. is there.

  In this way, it is possible to prevent the used tile carpet from becoming industrial waste and to discharge it to the outside as much as possible, and to provide a legally legal disposal method or system.

In order to achieve the above object, the present invention employs, for example, the following basic technical configuration.
That is, in a specific example of the tile carpet recycling and reuse system according to the present invention, the tile carpet user or owner who has signed a predetermined contract for tile carpet recycling and reuse by the tile carpet contractor. A first step of peeling the tile carpet that has been applied and used from an appropriate floor base under the control of

  The tile carpet that has been detached and used from the floor under the control of the user or owner is temporarily stored and collected from the user or owner, and a predetermined contract is made with the tile carpet contractor. A second step of carrying in the tile carpet recycling factory

  A plurality of used tile carpets collected and collected may or may not be washed, and the surface of the carpet layer or the backing layer surface of the tile carpet may have a carpet original fabric larger than the size of the tile carpet. A third step of forming a recycled tile carpet by pasting a surface opposite to the surface on which the carpet layer is formed (hereinafter simply referred to as the original fabric back surface) and then trimming to a predetermined size by an appropriate method;

The fourth step of returning the recycled tile carpet to a location designated by the user or owner so that the new carpet layer surface of the recycled tile carpet becomes the surface on an appropriate floor base surface designated by the user or owner. A fifth step of arranging and constructing the recycled tile carpet;
This is a tile carpet recycling and reuse system.

  Further, in the present invention, in the above-described steps, after the fifth step, if desired, the first to fifth steps are performed after the elapse of a predetermined period or after the elapse of the predetermined period. It is also possible to provide a sixth process in which is repeated.

  Conventionally, in order to renew dirty and used tile carpets, it has been common to first discard the currently used tile carpet and re-install the tile carpet. This is based on a methodology in which used tile carpet is once converted into industrial waste, and then an effective use of industrial waste is sought.

  By the way, the used or used tile carpet is not lost as its original function, except that its surface is dirty. In particular, the carpet layer, which accounts for the majority of the price, is very useful in terms of cushioning properties, loop properties, breathability, and heat retention.

  The inventors of the present invention pay attention to the useful part, stand on the idea of making the best use of this, and stand on the principle that industrial waste is not produced as much as possible. The handling of tile carpets has arrived in a completely different way.

  This method was made possible only by a technique for peeling and separating a tile carpet into a vinyl chloride backing material and a carpet layer in the shape as disclosed in Japanese Patent Application Laid-Open No. 2004-168023.

  That is, paying attention to useful parts of the used or used tile carpet, use the used or used tile carpet itself as a backing layer, or peel off the carpet layer from the used or used tile carpet. It is one aim of the present invention to recycle and reuse as a backing layer for new tile carpets, and the other is that in the process of renewing, industrial waste is not generated as much as possible in all processes, and is being used or used. The contractor who handles the finished tile carpet takes it from the owner or user of the building and transports it to the refurbishment factory where it is processed into a recycled tile carpet, and then joins the carpet layers obtained through the thickness reduction process as necessary. Forming a wide and long carpet layer, After the process of forming a recycled tile carpet by laminating the surface of the floor layer and the unused raw carpet fabric by an appropriate method and trimming them to a predetermined size, the recycled tile carpet is transported again to the same place. Or it is to establish a mechanism that can be reconstructed at a new location.

  The object of the present invention is to propose a method in which only the carpet layer on the surface is renewed while retaining the ownership to the owner or user of the building without making the used and used carpet tile as industrial waste as much as possible. It is.

  In other words, all tile carpet contractors involved in tile carpet refurbishment work need to remove the used tile carpet from the designated construction site without requiring a new relevant qualification, and leave it from the owner or user of the building. The purpose is to establish a mechanism in which after transporting and transporting to a recycling factory, the recycled tile carpet can be transported again and reconstructed at the same location or at a new location.

  In this way, it is possible to minimize the waste of the used tile carpet as industrial waste and to prevent it from being discharged as much as possible, and to provide a legally legal disposal method or system.

  In this way, the tile carpet that has been installed and used temporarily to be collected and collected from the user is to update only the carpet layer on the surface while retaining the ownership of the building owner or the user. The tile carpet that has been installed and in use is not industrial waste.

  An object of the present invention is to pay attention to the usefulness of a used tile carpet, and temporarily collect and collect it from a user who controls the tile carpet that has been used and used, and a carpet obtained through a thickness reduction process as necessary. Layers are joined together to form a wide and long carpet layer, the wide and long carpet layer surface and an unused raw carpet are laminated together by an appropriate method, and trimmed to a predetermined size to regenerate tile carpet The present invention is constructed and used in the present invention, characterized in that it is composed of the steps of forming the process, and further, if desired, the process is repeated after a predetermined period of time. This is achieved by adopting a tile carpet recycling and reuse system.

  Focusing on the usefulness of used tile carpets that have been treated as industrial waste, we have adopted the recycling and reuse system for used and used tile carpets of the present invention that has technical support to demonstrate its usefulness. By doing so, the used tile carpet as industrial waste is almost lost, and it becomes a socially useful thing.

  The used tile carpet according to the present invention has a wide and long tile carpet, that is, a tile carpet sheet layer, by joining a plurality of tile carpets to each other and joining them before joining the original carpet. The recycled tile carpet can be formed by pasting the wide and long tile carpet sheet layer and an unused carpet original fabric by an appropriate method and trimming them to a predetermined size.

  In other words, in the present invention, the collected used tile carpet is given a social status as a useful material again as a backing material for the recycled tile carpet.

  (1) Since used tile carpets have been treated as industrial waste, the contractor for tile carpet renovation work, which is a small business operator, is obliged to acquire qualifications, and the user has to pay extra costs as waste disposal costs. Although forced, the adoption of the constructed and in-use tile carpet recycling and reuse system of the present invention eliminates such problems.

  (2) Since the present invention adopts the above-described technical configuration, it is useful to pay attention to the usefulness of used tile carpets that have been treated as industrial waste and have been subject to strict legal regulations. By adopting the recycled and reused system for tile carpets that have been applied and used according to the present invention that has technical support to demonstrate the properties, used tile carpets as industrial waste are almost eliminated and become a socially useful product. .

  (3) The recycled tile carpet obtained by adopting the recycled and reused tile carpet system of the present invention in use and in use contains a backing material derived from the used tile carpet by 50% by weight. Therefore, it also fully meets the content rate standards for recycled products derived from the market, which are required for materials procured by public institutions such as government offices. In addition, since it satisfies the environmental improvement standard that does not discharge industrial waste required by ISO 14000, the product value of the product more than the conventional product derived from the virgin raw material can be realized and advantageous sales are possible.

  (4) After the vinyl chloride backing layer of the used tile carpet is separated and recovered from the used tile carpet, it can be reused as a backing material for other flooring materials in companies that have a factory to recycle. The carpet layer that is used is no longer industrial waste.

  (5) The carpet layer and the vinyl chloride backing layer constituting the tile carpet are both reused as useful materials, and the tile carpet is reused by adopting the recycled and reused tile carpet system of the present invention. If an effective and legal process can be established in all processes, from peeling of used and used tile carpets to the construction of recycled tile carpets, industrial waste derived from tile carpets will be almost zero and zero emissions will be realized. Can approach as much as possible

  (6) As described above, the conventional technique scrapes the carpet layer constituting the tile carpet and attaches only the vinyl chloride backing layer of the tile carpet to the new carpet layer as the backing layer of the recycled tile carpet. There is a concern about pollution problems due to the large amount of fiber scrap collected, and special consideration is required for the disposal method.

  On the other hand, in the present invention, the basic technique of using the carpet layer of the used tile carpet as the backing layer of the recycled tile carpet is to reuse both the carpet layer and the vinyl chloride backing layer. In the first specific example, the used tile carpet itself is used as the backing layer of the recycled tile carpet, and the carpet layer and the vinyl chloride backing layer constituting the tile carpet are separated from the used tile carpet. Then, the carpet layer is used as a backing layer for the recycled tile carpet, and the separated vinyl chloride backing layer is used for a backing layer of another carpet or other flooring material after appropriate regeneration treatment. Because the waste material from the treatment process of the present invention There is an effect to say that does not qualitatively occur. This method was made possible for the first time by a technique for peeling and separating a tile carpet into a vinyl chloride backing material and a carpet layer as disclosed in Japanese Patent Application Laid-Open No. 2004-168023.

  Further, in the present invention, if a carpet layer separated from a used tile carpet or a backing layer is bonded to a new carpet raw material by back-to-back, both sides of the recycled tile carpet have a pile layer. Therefore, the cushioning property is extremely large, the sound insulation and soundproofing effects are excellent, the thickness can be easily adjusted by pressure treatment, and the heat retention and breathability are also excellent. There is an advantage that construction and removal can be easily performed using a bonding method using a hook-and-loop fastener (such as a planar bonding material having a hook portion).

  Hereinafter, the present invention will be described with reference to specific configurations of the tile carpet regeneration and reuse system according to the present invention. However, the present invention is not limited thereto.

  That is, FIG. 1 is a flowchart showing the configuration of a specific example of the tile carpet recycling and reuse system according to the present invention. In the figure, the tile carpet contractor makes a predetermined contract for tile carpet recycling and reuse. A first step (S1) of peeling the tile carpet that has been installed and in use from an appropriate floor base under the control of the user or owner of the tile carpet being fastened;

  The tile carpet that has been detached and used from the floor under the control of the user or owner is temporarily stored and collected from the user or owner, and a predetermined contract is made with the tile carpet contractor. A second step (S2) for carrying into the tile carpet recycling factory having

  A plurality of used tile carpets collected and collected may or may not be washed, and the surface of the carpet layer or the backing layer surface of the tile carpet may be washed with a carpet raw material larger than the size of the tile carpet. A third step (S3) of forming a recycled tile carpet by pasting a surface opposite to the surface on which the carpet layer is formed (hereinafter simply referred to as the back side of the original fabric) and cutting it into a predetermined size by an appropriate method. ),

A fourth step (S4) of returning and carrying the recycled tile carpet to a location designated by the user or owner;
A fifth step (S5) of arranging and constructing the recycled tile carpet so that the new carpet layer surface of the recycled tile carpet becomes the surface of an appropriate floor base surface designated by the user or owner;

  After the fifth step, a sixth step (S6) in which the first to fifth steps are repeated after a predetermined period or after the predetermined period if necessary or necessary. A tile carpet recycling and reuse system is shown.

  In the first and second steps in the above specific example, the tile carpet construction company is peeled off from the appropriate floor base of the user who has concluded a predetermined contract and is being collected and used. Of tile carpets are transported to a recycling plant as used tile carpets.

  The predetermined contract concluded by the tile carpet contractor is a contract concluded between the user or owner, the recycle processor having the tile carpet recycling factory, and the tile carpet contractor. For example, a recycling processor peels off the tile carpet that has already been installed and used from the floor floor of the user or owner and temporarily stores and collects the tile carpet. It can be set to the content which prescribed | regulated the procedures, such as the process of carrying in to a factory and manufacturing a recycled tile carpet, and the arrangement | positioning construction process of the tile carpet construction contractor on the floor base surface which the said user or an owner designates the said recycled tile carpet.

  In addition, for maintenance after construction, it may be contracted for monthly, annual, and floor renewal at the time of refurbishment, and for each large-scale renovation work every 5 years, between the three contracting parties It may be described that the future policy will be discussed.

The used tile carpet 1 at that time is generally composed of a carpet layer 2 and a backing layer 3, and an example of a cross-sectional view thereof is shown in FIG.
In the present invention, as shown in FIG. 6A, the collected used tile carpet 1 in which the carpet layer 2 and the backing layer 3 are integrated is used as it is. Alternatively, as shown in FIG. 6 (B), a part or all of the backing layer 3 is peeled or removed from the tile carpet 1, and one of the appropriate base fabrics 66 is removed. The carpet layer 2 made of pile yarn is formed on the surface, and the backing layer 3 remains on the back surface of the base fabric 66, and the fiber binding layer 4 made of a resin component that binds the base fabric 66 and the pile yarn. The fiber forming material layer 10 may be used.

That is, in FIG. 6B, 4 is composed of a synthetic resin component such as vinyl chloride remaining on the back surface of the carpet layer 2 after the peeling or removing process.
Next, in the third step in the above-mentioned specific example of the present invention, a plurality of the collected and used tile carpets 1 are arranged adjacent to each other and are two-dimensionally arranged. A wide and long tile carpet sheet layer 15 that forms a flat surface may be formed.

  In this case, the plurality of tile carpets 1 may be arranged adjacent to each other without being joined to each other, and preferably, a two-dimensional plane is interposed via an appropriate reinforcing sheet as shown in FIG. A wide and long tile carpet sheet layer 15 may be formed. Further, after the end portions 11 of the plurality of used tile carpets are brought into contact with each other, the contact is made. The tile carpet sheet layer 15, which is a wide and long carpet layer, may be formed by joining the portions together with an appropriate fixing means 12 such as adhesion, adhesion, and fusion.

  In the present invention, the collected used tile carpet 1 or the wide and long tile carpet sheet layer 15 formed from the collected used tile carpet 1 is washed. It may be present or not washed.

  In the above specific example of the present invention, the used tile carpet 1 is the same as described above without peeling or removing all or at least a part of the backing layer 3. It can be used by joining together by the method.

FIG. 7A shows a plurality of collected used tile carpets 1 in which all or at least a part of the backing layer 3 remains, two-dimensionally arranged, and the end portions of the tile carpets 1. It shows that the wide and long used tile carpet 15 is obtained by being joined to each other as shown in FIG. Yes.

  The used tile carpet 1 in the present invention is a fiber-forming material layer having a structure in which a part or all of the backing layer 3 is peeled or removed from the tile carpet 1 as shown in FIG. 6 (B). Needless to say, it is also possible to form the fiber-forming material layer sheet layer 15 ′ as shown in FIG.

  In the present invention, the used tile carpet 1 collected as described above or its backing layer 3 is removed, and a fiber forming material layer 10 consisting only of the carpet layer 2 is used if necessary. As shown in FIG. 7C, the plurality of tile carpets 1 or the fiber-forming material layer 10 are appropriately bonded to each other, and the wide and long tile carpet sheet is washed. After the layer 15 or the fiber-forming material layer sheet layer 15 ′ is formed, the sheet layer 15 or 15 ′ may be executed by performing a cleaning process using an appropriate cleaning device or without performing a cleaning process. .

  Next, in the third step (S3) in the above specific example of the present invention, the wide and long tile carpet sheet layer 15 or the fiber-forming material layer sheet layer 15 ′ is used as an unused carpet raw material. Bonding with anti-20 by an appropriate method.

The unused carpet blank 20 used in the present invention is composed of a normal carpet layer, and the backing layer 3 is not formed.
That is, as shown in FIG. 8 (A), the unused raw carpet fabric 20 and the bonded wide and long tile carpet sheet layer 15 or the fiber-forming material layer sheet layer 15 ′ are appropriately bonded. The bonding means is not particularly limited, and a known adhesive is used with or without an appropriate film or auxiliary sheet interposed therebetween. Alternatively, it is possible to use known adhesive, fusion means or double-sided adhesive tape.

  As a joining method of the both, as shown in FIG. 8 (B), the carpet layer 2 of the wide and long tile carpet sheet layer 15 subjected to the joining treatment on the back surface 20-1 of the unused raw carpet 20 is used. The tile carpet sheet having a wide and long shape, which is joined to the back surface 20-1 of the unused raw carpet 20, as shown in FIG. 8C. The backing layer 3 of the layer 1 may be oppositely bonded.

  On the other hand, as another specific example, as shown in FIG. 8 (D), a wide and long fiber-forming material layer sheet layer 15 ′ subjected to the bonding treatment on the back surface 20-1 of the unused raw carpet 20 is used. The carpet layers 2 may be opposed to each other.

  As another specific example, as shown in FIG. 8 (E), a wide and long fiber-forming material layer sheet layer 15 ′ bonded to the back surface 20-1 of the unused raw carpet 20 is used. Alternatively, the fiber bonding portions 4 may be opposed to each other.

  Note that reference numerals 72 to 79 shown in FIGS. 8B to 8E are cut when the recycled tile carpet 30 is obtained by trimming the recycled tile carpet material manufactured by the above method by an appropriate method. A line is shown.

  That is, in another specific example of the present invention, as shown in FIG. 2, in the third step in the specific example, the collected and used tile carpet that has been collected and used in an appropriate method. The three-step process of forming the wide and long tile carpet sheet layer 15 and the surface of either the carpet layer surface 2 or the backing layer surface 3 of the wide and long tile carpet sheet layer 15 After pasting the back side of the carpet layer of the carpet original fabric, it may be composed of the step 3-2 of cutting the recycled carpet into a predetermined size by an appropriate method to form a recycled tile carpet. .

  By such treatment, the collected used tile carpet is utilized as a backing layer on the back surface of the carpet layer 2 of the carpet raw fabric 20 forming a new surface layer.

  In the present invention, an unused carpet layer is appropriately cut by combining the wide and long tile carpet sheet layer 15 formed as described above and the raw carpet back surface of the unused carpet layer. A plurality of new tile carpets 30 are formed by trimming to the size of a tile carpet having general dimensions.

  In the present invention, as a method for forming a wide and long carpet layer, for example, the adjacent edge of the carpet layer 2 obtained by removing the tile carpet 1 or the backing layer 3 of the tile carpet 1 is used. Whether to use appropriate adhesives, adhesives, double-sided adhesive tape, heat-sealing, or stitching, with or without end-to-end reinforcement sheets It is desirable to heat the built-in metal foil by induction heating, or to form a wide and long carpet layer by dielectric heating or ultrasonic processing.

Specific examples of the typical configuration of the recycled tile carpet 30 formed in the present invention are shown in FIGS. 9A to 9F.

  In the present invention, when the above-described recycled carpet reuse system according to the present invention is executed four times, any surface of the recycled tile carpet 30 "shown in (3) of FIG. And another carpet fabric 20 "'.

  Specifically, preferably, the recycled tile carpet 30 ″ shown in (3) of FIG. 9 (E) is appropriately compressed as necessary to adjust its thickness appropriately, and then the FIG. The carpet layer body 40 ′ functioning as a backing layer of the recycled tile carpet 30 ″ shown in (3) of FIG. 3) is bonded to the back surface of a new original carpet 20 ″ ′.

  Since the recycled carpet 30 ″ ′ of the present invention obtained in the fourth round shown in FIG. 9F in this specific example is composed of three layers, the same three-layer structure in that respect is shown in FIG. It has the same configuration as the recycled tile carpet 30 ′ obtained in the second round as shown in C) or (D).

  In the specific examples of FIGS. 9E and 9F, an example in which the fiber forming material layer 10 and the fiber forming material layer sheet layer 15 ′ are used as a tile carpet is shown. In this specific example, a backing is used. It goes without saying that the tile carpet 3 or the tile carpet sheet layer 15 having the layer 3 and the carpet layer 2 can also be used.

  Also, P1 to P5 shown in FIG. 9 are formed between adjacent recycled tile carpets when used tile carpets are interconnected to form a wide and elongated recycled carpet layer. It is a contact muscle.

  In the present invention, the recycled tile carpet 30 formed in this way is returned to the place designated by the user, and an appropriate floor base surface designated by the user, in many cases as described above. In the first step, the recycled tile carpet 30 is placed and installed in the place where the recycled tile carpet peeled off from the floor base during use is present so that the carpet layer surface 2 of the new tile carpet 30 becomes the surface. To do.

  In the fifth step after the fourth step of bringing the recycled tile carpet 30 into the location designated by the user in the present invention, the location designated by the user by the recycled tile carpet 30 If the area does not reach the required area, it is possible to use a recycled tile carpet prepared in advance.

  Recycled tile carpets are only used for renovations. Therefore, of course, the building has already been made and both Chile and Door Chile have already been decided. Since it is the flooring used here, the thickness of the recycled tile carpet cannot be selected other than according to the existing or according to the client's request. Therefore, it is necessary to adjust the thickness of the used tile carpet in the recycling process.

  That is, it is desirable that the step of forming the recycled tile carpet further includes a thickness reduction step of reducing the thickness of the used tile carpet temporarily stored and collected from the user. The thickness reduction step takes into account the allowable thickness of the recycled tile carpet from the thickness of the recycled tile carpet and the allowable height from the appropriate floor base surface specified by the user, It is a preferable aspect that a step of adjusting the height is included.

  Specifically, the thickness reducing step in the present invention includes compressing the thickness of the used tile carpet 1 or the carpet layer 2 of the tile carpet sheet layer 15 or using a synthetic resin such as vinyl chloride. This can be realized by removing or peeling part or all of the backing layer 3.

As shown in FIG. 10, it is necessary that the thickness of the recycled tile carpet 30 formed by repeating the first to sixth steps a predetermined number of times does not exceed the thickness of the door chilli portion 86. is there.
Chile is generally defined as a step at the boundary of the finished surface.

  As shown in FIG. 10, a tile finishing material 84 such as a tile carpet or a carpet is disposed on a floor base 87 made of a concrete slab or the like via an appropriate adhesive or the like, and at the same time the door portion 81 corresponds. A chile portion 85 is provided on the surface portion of the floor base 87, and a door chile portion 86 is provided at an end portion of the chile portion 85 facing the opening / closing direction.

In general, the height of the door chilli portion 86 is set to be substantially the same as the thickness of the floor finish 84.
The dust (or door dust) is preferably equal to or greater than the floor finish thickness.
When the floor finish thickness exceeds Chile (or Door Chile) (1) If it is Chile, kick it.
(2) In the case of doors and dust, the doors will not open.
In the case of the present invention, since it is a tile carpet, it is acceptable even if it is slightly thick (up to 2 mm), but the door is rubbing, and the carpet layer is worn and unsightly for a long time.

The floor finish thickness should be as close as possible to dust (or door dust).
If it is extremely thin, the pedestrian will feel a level difference and step on it.
As is apparent from the above description, the thickness of the recycled tile carpet is reduced because the thickness of the recycled tile carpet is an important requirement in the manufacturing process of the recycled tile carpet in the present invention. A process is required.
The thickness reduction process that can be used in the present invention will be described below.

  In the present invention, the thickness reducing step determines the allowable thickness of the recycled tile carpet from the thickness of the regenerated tile carpet 30 and the allowable height from the appropriate floor base surface specified by the user. In consideration, it is desirable to include a step of adjusting the height thereof. More specifically, the thickness reduction step is a method of removing the backing layer of the tile carpet, and the removal of the backing layer. The method squeezes the gap between a pair of rolls having a rotational difference to be equal to or less than the thickness of the vinyl chloride backing layer of the tile carpet, and the heated tile carpet is provided with the vinyl chloride backing layer on the earlier roll side of the pair of rolls. In this way, by passing through the gap, the interlayer between the carpet layer and the vinyl chloride backing layer is displaced, and the vinyl chloride backing layer is peeled off. Caused thereby, a method of separating a layer of suitable thickness of the vinyl chloride backing layer from the tile carpet.

More specifically, the vinyl chloride backing layer can be separated from the tile carpet by generating delamination using an apparatus as shown in FIG.
Here, if the thickness reduction process shown in FIG. 11 is described in detail, as shown in FIG. 11, it is a method of removing at least a part of the backing layer 3 of the tile carpet 1 and includes a pair of rotation differences. The gap 23 between the rolls 21 and 22 is squeezed below the thickness of the vinyl chloride backing layer 3 of the tile carpet, and the heated tile carpet 1 is placed so that the backing layer 3 comes to the earlier roll side 22 of the pair of rolls. Therefore, it is desirable that the vinyl chloride backing layer 3 is separated from the tile carpet 1 in which separation occurs between the carpet layer 2 and the backing layer 3 by passing through the gaps 23 and separation occurs.

  Furthermore, as another specific example of the thickness reducing step in the present invention, as shown in FIG. 12A, by using a scraper blade 600, the backing layer 3 is scraped off by an appropriate thickness. A method of separating at least a part of the backing layer 3 from the tile carpet 1 may be used. Alternatively, as shown in FIG. A method of separating at least a part of the backing layer 3 from the tile carpet 1 by scraping off the thickness may be used. As another specific example, as shown in FIG. 12C, a band knife splitter 602 is used. The carpet layer 2 composed of the pile 62 planted on the base fabric 66 and a part of the backing layer 3 or the carpet layer 2 and the carpet layer 2. It may be a method of separating at least a portion of the backing layer 3 from the tile carpet by slicing the boundary between the backing layer 3.

  On the other hand, as another specific example of the thickness reducing step in the present invention, a tile carpet sheet layer or a fiber-forming material layer sheet layer formed in a wide and long shape is formed through a reinforcing sheet. In the case of forming the wide and long layer, the thickness of the reinforcing sheet may be adjusted, or the backing layer may be formed from the collected used tile carpet. When separating and separating the film, the thickness of the backing layer may be adjusted.

  As described above, the method for reducing the thickness of the tile carpet in the present invention is a method of removing the backing layer 3 constituting the tile carpet 1 or cutting and grinding the backing layer 3 by a predetermined thickness, or the regeneration. Not only the method of heating and compressing the tile carpet, but also separating the original recycled tile carpet 30, 30 ′, 30 ″ used as the backing layer of the recycled tile carpet from the recycled tile carpet 30 ′, 30 ″, 30 ″ ′. Including the case of removing.

  Further, the thickness reducing step in the present invention is such that the thickness of the collected used tile carpet or the carpet layer constituting the fiber forming material layer is adjusted through a heat and pressure treatment. It may be configured.

  That is, the thickness reducing step compresses the carpet layer by, for example, heating the peeled and separated carpet layer to 150 ° C. to 200 ° C. and passing it between rolls narrowed to a gap smaller than the thickness of the carpet layer. This is a method of reducing the thickness or a method of reducing the thickness by compressing the carpet layer by heating the carpet layer separated and separated to 150 ° C. to 200 ° C. and pressing the carpet.

A specific example of another processing method for realizing the thickness reduction process in the present invention will be described in detail with reference to FIGS.
In the present invention, the pressure reduction treatment of the carpet layer in the thickness reduction step employs the principle of heating and compression setting utilizing the characteristics of the thermoplastic resin constituting most of the carpet layers.

  Specifically, as shown in FIG. 13, the tile carpet 1 or the fiber forming material layer 10 or the tile carpet sheet layer 15 or the fiber forming material layer sheet layer 15 ′ to be subjected to thickness reduction is conveyed by a rotating conveyor 26. And it heats to 140 to 200 degreeC with the hot air heating furnace 24 which incorporates the hot air blower 25 in the middle. The rotating steel belt conveyor 26 then passes through a cold press 27 whose temperature is adjusted to 20 ° C. to 80 ° C. and is compression set.

  The other specific example of the thickness reduction process in the present invention is the same as the principle of heating and compression setting using the characteristics of the thermoplastic resin constituting most carpet layers, but as shown in FIG. The tile carpet 1, the fiber forming material layer 10, the tile carpet sheet layer 15 or the fiber forming material layer sheet layer 15 ′ to be subjected to thickness reduction is conveyed by a rotating conveyor 26, and a hot air blower 25 is turned on the way. It heats at 140 to 200 degreeC with the hot-air heating furnace 24 incorporated. The heated il carpet 1 or the fiber-forming material layer 10 or the tile carpet sheet layer 15 or the fiber-forming material layer sheet layer 15 ′ passes through the chute 29 and is paired with a pair of rolls whose temperature is adjusted to 20 ° C. to 80 ° C. Is compressed and set.

  The heating and pressing process in FIG. 13 is preferably used mainly for the tile carpet 1 or the fiber forming material layer 10, and the heating and pressing process in FIG. 14 is preferably used mainly for the tile carpet sheet layer 15 or the fiber forming material layer sheet layer 15 ′. Is done.

  Heating to 140 ° C. to 200 ° C. in the hot air heating furnace 24 is to bring out the characteristics of the thermoplastic resin constituting the carpet layer, and at 140 ° C. or below, the carpet layer is not heated sufficiently and the subsequent compression set is sufficient. On the other hand, if the temperature exceeds 200 ° C., some fibers may melt out and the purpose cannot be achieved.

  In the compression setting process, the temperature is adjusted to 20 ° C. to 80 ° C. If the temperature is 20 ° C. or less, the temperature of industrial water must be cooled by a chiller machine or the like, resulting in extra costs. Above 80 ° C, the temperature is too high and there is a risk that sufficient setting will not be performed.

  As yet another specific example of the tile carpet recycling and reuse system according to the present invention, as shown in FIG. 3, a tile carpet contractor has signed a predetermined contract for tile carpet recycling and reuse. An eleventh step (S11) of peeling the tile carpet 1 that has been installed and in use from an appropriate floor base under the control of the user or owner of the tile carpet.

  The tile carpet 1 that has been detached and used from the floor under the control of the user or owner is temporarily stored and collected from the user or owner, and a predetermined contract is made with the tile carpet contractor. A twelfth step (S12) for carrying into a tile carpet recycling factory having

A thirteenth step (S13) of removing the backing layer 3 of the carpet 1 without cleaning the collected tile carpet 1 that has been applied and in use;
The fiber-forming material layer 10 mainly composed of the carpet layer 2 obtained by removing the backing layer 3 or the back surface opposite to the surface on which the carpet layer 2 is formed (hereinafter simply referred to as fiber formation). The surface opposite to the surface on which the carpet layer 2 is formed (hereinafter simply referred to as the original reverse surface) of the carpet original fabric 20 having a size larger than the size of the tile carpet 1 on either surface of the material layer reverse surface). After pasting 21, a fourteenth step (S14) of forming the recycled tile carpet 30 by trimming to a predetermined size by an appropriate method,

A fifteenth step of returning and carrying the recycled tile carpet 30 to a location designated by the user or owner (S15)
A sixteenth step (S16) of arranging and constructing the recycled tile carpet 30 so that the new carpet layer surface 20 of the recycled tile carpet 30 becomes the surface of an appropriate floor base surface designated by the user or owner;

  After the sixteenth step, if necessary, a seventeenth step (S17) in which each of the eleventh to sixteenth steps is repeated after a predetermined period or after the predetermined period has elapsed. Is a tile carpet recycling and reuse system.

  The basic technical configuration in this specific example is substantially the same as the above-described specific example, but as a different technical configuration, as shown in FIG. 4, the collected backing layer of the used tile carpet 1 is used. 3 is separated and removed in advance to form a fiber forming material layer 10 without the backing layer 3, and the fiber forming material layer 10 is bonded to the carpet raw fabric 20.

  Next, in this specific example, a plurality of fiber-forming material layers 10 obtained by removing the backing layer 3 of the collected used tile carpet 1 in the fourteenth step (S14). Are arranged as they are, or they are joined together by an appropriate method, and a wide and long fiber-forming material layer sheet layer 15 ′ is formed with or without washing.

  That is, in the fourteenth step (S14) in this specific example, the fiber forming material layer 10 obtained by removing the backing layer 3 is connected by an appropriate method to form a wide and long fiber. On the surface of either the carpet layer surface 20 or the fiber-forming material layer back surface 4 of the 14-1 step of forming the material layer sheet layer 15 ′ and the wide and long fiber-forming material layer sheet layer 15 ′, After the carpet original fabric 20 and the carpet layer original fabric rear surface 20-1 are attached, the carpet tile fabric 20 is cut into a predetermined size by an appropriate method to form a recycled tile carpet. Is also a preferred specific example.

Further, the method of arranging the plurality of fiber forming material layers 10 in this specific example adjacent to each other and connecting the adjacent portions is the same as the method of the specific example.
The outline of the structure of the wide and long fiber-forming material layer sheet layer 15 ′ formed in this specific example is shown in FIG. 7B, and further in this specific example. A configuration example of the regenerated tile carpet 30 formed in the 14th step is as shown in FIGS. 8D and 8E.

  Further, the tile carpet or the fiber-forming material layer manufactured according to this specific example is simply arranged adjacent to each other, and the wide and long tile carpet layer 15 or the fiber-forming material layer sheet layer 15 ′ is used. The configuration of the recycled tile carpet 30 is also substantially as shown in FIGS. 8D and 8E.

  On the other hand, as this specific example, as shown in FIG. 8D, the unused carpet original fabric 20 and the fiber-forming material layer sheet layer 15 ′ are joined as shown in FIG. 20 may be bonded oppositely to the carpet layer 2 of the wide and long fiber-forming material layer sheet layer 15 ′ on the back surface 20-1, and as another specific example, As shown in FIG. 8 (E), the fiber bonding layer surface 4 of the wide and long tile carpet 15 ′ subjected to the bonding treatment is bonded to the back surface 20-1 of the unused raw carpet fabric 20 so as to face each other. There may be.

  In the present invention, the method of successively stacking the thickness of the carpet original fabric and the recycled carpet one after another is always stuck due to the existing dust or door dust. The third round can be used as a backing layer for the carpet without peeling off the recycled carpet 30 in the second round, and a method of pasting the original carpet as it is can be taken, but in many cases it cannot be used practically. Therefore, after the third round, after separating the used recycled carpet 30 into a carpet layer and a backing layer of the used tile carpet, the separated carpet layer or backing layer is used as a new backing layer. The carpet raw fabric 20 is joined.

  The backing layer in the above-described process may be a vinyl chloride backing layer, a recycled tile carpet layer used in the previous cycle, or separated from the re-carpet used in the previous cycle. Includes a carpet layer.

  In this specific example, the thickness reducing step is a step of separating the carpet layer of the used tile carpet and the vinyl chloride backing layer or the recycled tile carpet layer by hot air or heating the used tile carpet. Or after the used tile carpet is heated, the moving direction of the heated used tile carpet is steep during the movement. It may be executed by changing to.

  Therefore, as a method for easily peeling the recycled tile carpet having the loop layer on the back surface, it is effective to join the fiber forming material layer sheet layer and the carpet raw fabric with a double-sided adhesive tape or an adhesive.

  Further, in the present invention, in any of the above specific examples, the carpet original fabric 20 is bonded to the wide and long tile carpet 15 or the wide and long fiber forming material layer sheet layer 15 ′. When the predetermined recycled tile carpet 30 is cut out from the long recycled tile carpet original fabric, the straight line of the joint portion 11 formed on the wide elongated tile carpet layer 15 or the fiber-forming material layer sheet layer 15 ′. It is desirable to cut out at portions 72 to 79 that do not overlap the shape portion.

  In the present invention, the recovered used tile carpet is utilized as a backing layer on the back surface of the carpet layer 2 forming a new surface layer by such treatment.

In the present invention, an unused carpet layer formed as described above is trimmed to the size of a tile carpet having general dimensions using an appropriate cutting method, and a plurality of new tile carpets are obtained. 30 is formed.
In the present invention, the above-described steps are repeatedly repeated after an elapse of a predetermined period, for example, through an interval of one year to several years, if desired.

  In the present invention, the recycled tile carpet 30 formed in this way is returned to the place designated by the user, and an appropriate floor base surface designated by the user, in many cases as described above. In the first step, the recycled tile carpet 30 is placed and installed in the place where the recycled tile carpet peeled off from the floor base during use is present so that the carpet layer surface 2 of the new tile carpet 30 becomes the surface. To do.

  Therefore, as described above, in the third step and the fourteenth step of the present invention, when the used tile carpet is used as the backing layer of the new tile carpet, the sixth step is performed. In order to be able to be used for the subsequent repeated use required in the process or the 17th process, a process for limiting the thickness in the recycling process of the used tile carpet is required.

  That is, in the present invention, as described above, in the step of forming the recycled tile carpet 30, the thickness reduction that further reduces the thickness of the used tile carpet 15 temporarily stored and collected from the user. It is desirable that the process is included.

  Furthermore, as another specific example in the present invention, in the above-mentioned specific examples, a wide and long unused unused surface of either the carpet layer surface or the backing layer surface of the collected used tile carpet is used. Although the carpet original fabric 20 was joined, in this specific example, the carpet cut out from the carpet original fabric having a tile carpet size on either the carpet layer surface or the backing layer surface of the collected used tile carpet. It is also possible to apply a layer to form a recycled tile carpet.

  As shown in FIG. 5, the operation procedure in this specific example is under the control of a tile carpet user or owner who has signed a predetermined contract regarding tile carpet remanufacturing. A thirty-first step of peeling the applied and used tile carpet from an appropriate floor base in

  The tile carpet that has been peeled off and used from the floor under the control of the user or the owner is temporarily stored and collected from the user to the tile carpet recycling plant controlled by the tile carpet installer. 32nd process of carrying in,

  Either the carpet layer surface of the collected tile carpet or the backing layer surface is attached to either the carpet layer surface or the backing layer surface of an unused tile carpet having an unused tile carpet size or a backing layer. A thirty-third step of forming a tile carpet;

A thirty-fourth step of returning and carrying the recycled tile carpet to a location designated by the user;
A thirty-fifth step of arranging and constructing the recycled tile carpet such that the new carpet layer surface of the recycled tile carpet is a surface on an appropriate floor base surface designated by the user;

A thirty-sixth step in which the thirty-first to thirty-fifth steps are repeated after the thirty-fifth step, after a predetermined period or after the predetermined period, if desired
This is a tile carpet recycling and reuse system.

  In the present invention, while the system according to the present invention is repeated, there remains a used backing layer in which the carpet layers are laminated together. In the backing layer, one streak is generated one by one in the order of contact and joining. The used backing layer, which is a back-to-back bonding of the extra carpet layers generated in a specific round of the system, has already played a role in the previous round, so it is in contact with each other vertically and horizontally. There is a streak. This streak appears as a slight step on the surface of the recycled tile carpet and impairs the beauty. In addition, when this backing layer is used, there are three contact bars, which are difficult to see. Therefore, it is desirable to abandon the use of this backing layer for recycled tile carpet and to use it for civil engineering materials such as planting floors.

  Furthermore, the backing layer is not used as a backing layer. For example, a plurality of holes of a predetermined size are intermittently formed to improve drainage and used for a drainage mechanism, artificial grass or natural grass. It may be used as an auxiliary material for curing or holding.

  In the present invention, when the recycled tile carpet is reconstructed, a normal construction method using an adhesive can be used to reconstruct the recycled tile carpet, but the back surface of the recycled tile carpet is a loop. Construction using a surface fastener (such as Velcro (trademark)) is preferably used.

  In the case of a normal construction method using an adhesive, the floor surface becomes sticky with the adhesive, and the socks and work clothes of the installer and electrician are stained, and the back surface of the recycled tile carpet is looped. Adhesive fills the loop surface, impairing the original cushioning property, making it impossible to reuse the recycled tile carpet again.

  In the case of construction with a loop-like fastener that uses the loop shape, the floor base surface is not sticky with adhesive, so it does not stain the socks and work clothes of installers and electricians, and recycled tile carpet It is possible to make full use of the cushioning property due to the back surface of the loop, and the recycled tile carpet can be reused again. The back surface of the recycled tile carpet can be used as a backing material for the next recycling.

Details of specific examples of the recycled tile carpet and the tile carpet recycling and reuse system according to the present invention will be described below.

(3) The tile carpet deposited from this office has a carpet layer of 3.0 mm, a vinyl chloride backing layer of 5.0 mm, and a total thickness of 8.0 mm. Therefore, in this office, the door dust is set to 9.0 mm. It was. At the request of the office building user, the renovation was to change the carpet layer thickness to 4.0 mm. Therefore, to match the existing door dust, the recycled tile carpet has a thickness of the carpet layer. The thickness of the backing layer derived from the deposited tile carpet is adjusted to 4.0 mm through the thickness reduction process so that the thickness of the backing layer derived from the deposited tile carpet is 4.0 mm and the total thickness is 8.0 mm. There was a need. First, after cleaning the installed and used tile carpet to remove dirt and dust, the gap between the pair of rolls with a difference in speed is set to be equal to or less than the thickness of the vinyl chloride backing material of the tile carpet. It was decided to peel off the vinyl chloride backing material of the tile carpet by heating and passing the tile carpet that had been installed and being used and applying a pressing elastic force. In the method of separating and recovering tile carpet and vinyl chloride backing material that causes peeling by applying a pressure resilience to the heated tile carpet, the heating temperature affects the separation and recovery rate of the vinyl chloride backing material, and the vinyl chloride backing material Utilizing the effect of the separation recovery rate on the thickness of the vinyl chloride backing material left on the peeled carpet layer, the residual vinyl chloride backing material that fits this office door chile was peeled off. In order to determine the thickness of the carpet layer, the heating temperature was set to 180 ° C., and 4.0 mm of the original 5.0 mm vinyl chloride backing layer was selectively peeled off to obtain a carpet having a total thickness of 4.0 mm. A backing layer consisting of layers was prepared.

  The edge portions of the carpet layers from which the vinyl chloride backing material was peeled were joined to each other by ultrasonic processing to form a carpet layer sheet layer 15 having a width of 1,030 mm and a long width.

  (4) The width of the 1,030 mm wide and long carpet layer sheet layer 15 and the unused carpet original fabric are arranged so that the loop layers of each other come to the outside so that the unused carpet original fabric can be stopped.

Cleaning maintenance, all floor maintenance once a year, large-scale maintenance once a year, and maintenance when changing the room layout. During each maintenance, the user of the office building, the tile carpet installer, and the manufacturer who has the tile carpet recycling factory will consult and take into account the degree of dirt on the tile carpet on the office floor, and then perform part or all of the tile carpet regeneration work. There is a clause that repeats the above process by deciding whether to use it or to continue using it, but it is decided to repeat the above process after consulting with the three companies prior to the large-scale maintenance once every five years. Reconstruction work was put in.

  In a 1,000 square meter office under the control of the user who removed the tile carpet from the tile carpet installer, the border of the room was cut to match the dimensions of the room, and the tile carpet was cut accordingly. Recycled tile carpet cut to 500-square size formed through steps (3) and (4) using a carpet layer from which vinyl chloride backing material has been peeled off from tile carpets peeled off from other offices. At the same time, it was returned and carried in along with the recycled tile carpet.

(1) A user of an office building, a tile carpet contractor, and a manufacturer that has a tile carpet recycling plant have contracted with three companies. Peel off,
(2) The used and used tile carpet that has been peeled off from the user is deposited and brought to a tile carpet recycling factory, one of the parties to the contract,

  (3) The tile carpet deposited from this office has a carpet layer of 7.0 mm, a vinyl chloride backing layer of 3.0 mm, and a total thickness of 10.0 mm. Therefore, in this office, the door dust is set to 11.0 mm. It was. At the request of the office building user, this renovation was to change the thickness of the carpet layer to 7.0 mm. In order to match the existing door dust, the recycled tile carpet has a thickness of the carpet layer. The thickness of the backing layer derived from the deposited tile carpet is adjusted to 3.5 mm through the thickness reduction process to 7.0 mm, the thickness of the backing layer derived from the deposited tile carpet is 3.5 mm, and the total thickness is 10.5 mm. There was a need.

  First, after cleaning the installed and used tile carpet to remove dirt and dust, the gap between the pair of rolls with a difference in speed is set to be equal to or less than the thickness of the vinyl chloride backing material of the tile carpet. It was decided to peel off the vinyl chloride backing material of the tile carpet by heating and passing the tile carpet that had been installed and being used and applying a pressing elastic force.

  In the method of separating and recovering tile carpet and vinyl chloride backing material that causes peeling by applying a pressure resilience to the heated tile carpet, the heating temperature affects the separation and recovery rate of the vinyl chloride backing material, and the vinyl chloride backing material Utilizing the effect of the separation recovery rate on the thickness of the vinyl chloride backing material left on the peeled carpet layer, the residual vinyl chloride backing material that fits this office door chile was peeled off. In order to determine the thickness of the carpet layer, the heating temperature was set at 200 ° C., and most of the original 3.0 mm vinyl chloride backing layer was peeled off to obtain a 7.0 mm thick carpet layer.

  The edges of the carpet layers from which the vinyl chloride backing material was peeled were joined together by ultrasonic processing to form a wide and long carpet layer sheet layer 15 having a width of 1,030 mm. A backing layer comprising a wide and long carpet layer sheet layer 15 comprising a carpet layer having a total thickness of 3.5 mm was prepared by heating and compression.

  (4) A vinyl chloride sol used for sealing the unused carpet original fabric, with the long carpet layer and the unused carpet original fabric having a width of 1,030 mm arranged so that the loop layers of each other come outside. Use as an adhesive, and laminate to 500 squares to form a recycled tile carpet.
