Description

The present invention relates to a reuse system and a reuse method for tile carpets removed from a laying place.

Conventionally, a method of cleaning and reusing used tile carpet has been proposed. For example, Japanese Patent Application Laid-Open No. 2002-70299 (Patent Document 1) discloses that the removed tile carpet is washed while being pressed with a roll brush. Further, it is disclosed that a tile carpet that has been washed and finished as new as possible and a new tile carpet are combined and re-laid on the base.

Further, in Japanese Patent Application Laid-Open No. 2003-41759 (Patent Document 2), a crushed tile carpet that has become unusable is subjected to volume reduction treatment to generate a high-density fiber aggregate impregnated and fixed with a thermoplastic resin. It is disclosed to do. It is disclosed that a tile carpet is obtained by laminating a surface pile on the backing layer, which is obtained by hot-press molding the powder or granular material of the high-density fiber aggregate.

Although reuse techniques such as those in Patent Documents 1 and 2 are known, tile carpets that are still usable may be discarded without being reused. For example, when a rental office building is newly constructed, a standard tile carpet is laid on the floor of the building. When a resident moves into a room in a building, some or all of the tile carpet on the floor may be replaced with his own. In this case, the original building standard tile carpet is often discarded even though it is in the same condition as new.

The inventors examined a mechanism for purchasing and storing tile carpets that had been discarded in the past, and providing them as needed. In this study, the inventors found the following problems. For example, if the person who laid the tile carpet is different from the person who removes and stores the tile carpet, the lot information about the removed tile carpet becomes unknown. Therefore, when re-laying the tile carpet that has been removed and stored, a plurality of tile carpets having the same product number but different lots may be laid in one laying area. Even if the product number is the same, the appearance of the tile carpet may be slightly different if the lot is different. In this case, it was found that a slight difference in color tone may be visually recognized between a plurality of tile carpets in one re-laid laying area.

Therefore, the present invention provides a tile carpet reuse system and a tile carpet reuse method that can secure the texture of the tile carpet in the laying area in consideration of the difference in color tone due to the difference in lot in the re-laid tile carpet. The purpose is to do.

The tile carpet recycling system according to one aspect of the present invention accepts input of information regarding the redelivered tile carpet that has been laid and then removed, and indicates the part number, lot information, and storage time of the redelivered tile carpet. Access the recording unit, the registration unit that records in the recording unit in association with the above, the request reception unit that accepts the input of the part number of the tile carpet to be newly laid, and the quantity of tile carpet for each laying area. , The redelivery tile carpet having the same product number as the product number received by the request reception unit, and the redelivery tile carpet satisfying the conditions of the lot information and the storage time predetermined, is said for each laying area. It includes an extraction unit that extracts the quantity received by the request reception unit, and an output unit that outputs the information of the redelivered tile carpet extracted by the extraction unit as the tile carpet information for laying in the laying area.

According to the above configuration, the part number, lot information, and storage time information of the redelivered tile carpet that is removed and placed in the storage place are associated and recorded. This saves lot information for the removed redelivered tile carpet. The extraction unit extracts information on the quantity of redelivered tile carpet required in each laying area from the recording unit with the product number received by the request reception unit. The extraction unit extracts the redelivered tile carpet that satisfies the conditions for which the lot information and the storage time are predetermined for each laying area. Thereby, not only the product number but also the lot and the storage time can be taken into consideration to extract the redelivered tile carpet for laying in each laying area. The information of the redelivered tile carpet extracted by the extraction unit is output as the information of the tile carpet for laying in the laying area. Therefore, it is possible to extract the redelivered tile carpet in consideration of the difference in color tone due to the difference in lot in the laying area and output the information. As a result, the texture of the tile carpet can be ensured in consideration of the difference in color tone due to the difference in the lot of the redelivered tile carpet in the laying area. The redelivered tile carpet includes a tile carpet that has been laid and then removed, that is, a tile carpet that has already been laid. For example, a tile carpet as good as new, which is laid in the laying area and then removed before the resident moves into the laying area, is also a redelivered tile carpet. The redelivered tile carpet can also be referred to as a used tile carpet.

Here, the lot information is information for identifying a production lot. For example, one production using the same production line, that is, tile carpets of one product number produced in one operation of the production line are in the same lot. Tile carpets of the same part number produced in a single production will have a nearly uniform finish. Different lots of tile carpets with the same part number may have slightly different finishes. For example, when tile carpets having the same part number are manufactured on different days using the same production line, the finish of the tile carpet differs slightly depending on the manufacturing date. Even if the production line and product number are the same, if the production dates are different, the lots are different. If tile carpets of the same part number are manufactured in multiple times on the same production line on the same day, the lot will be different for each time. The quantity produced in one production, that is, the quantity of one lot is not particularly limited. The quantity of one lot is set as appropriate according to the order, inventory and other conditions. The lot information can be, for example, a lot identification code. The lot identification code can be represented by, for example, a number indicating a lot, a character string, a bar code, or the like.

The laying area is a unit of the area where one product number tile carpet is laid. It is preferable that the appearance of a plurality of tile carpets of the same part number laid in one laying area is uniform to some extent in the laying area. That is, the laying area is a unit of the laying area where the uniformity of the tile carpet is required. For example, one room without a break can be one laying area. Further, when one room has a plurality of sections separated by partitions, walls, etc., each section may be used as one laying area. Further, for example, there may be a plurality of laying areas on one floor of the building.

In the above system, the extraction unit sets the number of redelivered tile carpets in each laying area received by the request reception unit in each laying area within a predetermined range of the number of lots of tile carpets in each laying area. It may be extracted so as to be. As a result, the variation in lots of redelivered tile carpets laid in each laying area can be kept within a predetermined range. Therefore, for example, it is possible to make it more difficult for color unevenness due to the difference in lots to occur in the laying area, and it is possible to enhance the sense of unity of the laid tile carpet. As a result, the texture of the tile carpet in the laying area can be maintained or improved as if it were new, in consideration of the difference in color tone due to the difference in lot.

In the above system, the extraction unit stores the number of redelivered tile carpets in each laying area received by the request reception unit in each laying area so that the number of lots is within a predetermined range. It may be extracted in the order of earliest time. As a result, the lot variation of the redelivered tile carpet laid in each laying area can be kept within a predetermined range, and the one having a long storage period can be preferentially reused. Therefore, for example, color unevenness due to a difference in lot and a difference in storage period can be less likely to occur in the laying area, and the sense of unity of the laid carpet can be enhanced. In addition, the storage period of the redelivered tile carpet can be shortened, and the lot difference of the redelivered tile carpet stored in the warehouse can be reduced.

In the system, at the storage location, a plurality of the redelivered tile carpets having the same part number and lot may be arranged and stored in one box or on one pallet. The registration unit can record the product number, the lot information, the storage time, and the information for identifying the box or pallet in the recording unit in association with each other. In this case, the extraction unit may extract information that identifies a box or pallet of the redelivered tile carpet that satisfies the above conditions. The output unit may output the information of the box or pallet extracted by the extraction unit as the information of the tile carpet for laying in the laying area. As a result, it is possible to improve the work efficiency of placing, taking out, and transporting the redelivered tile carpet in the storage place. By improving these work efficiencies, it is possible to shorten the period from the removal of the redelivered tile carpet to the redelivery. Therefore, the lot difference of the redelivered carpet can be further reduced. As a result, for example, the effect of ensuring the texture of the tile carpet, such as eliminating color unevenness in the laying area and improving the sense of unity of the carpet, can be further enhanced.

In the system, the registration unit may record information indicating the position of the box or pallet in the storage location in the recording unit as information for identifying the box or pallet. The output unit may output information indicating the position of the box or pallet extracted by the extraction unit in the storage location as information on the tile carpet for laying in the laying area. As a result, the work efficiency of placing, taking out, and transporting the redelivered tile carpet to the storage place can be further improved. By improving these work efficiencies, it is possible to shorten the period until the redelivered tile carpet is delivered again. As a result, the effect of ensuring the texture of the tile carpet can be further enhanced.

A method of reusing a redelivered tile carpet according to one aspect of the present invention includes a step of removing the tile carpet with the product number and lot information and transporting the tile carpet as a redelivered tile carpet, and for each of the redelivered tile carpets. A sorting step of determining the degree of contamination and selecting whether to wash and reuse according to the judgment result, and a redelivery tile carpet determined to be washed and reused in the sorting step. When a request for a tile carpet with a specified product number and quantity for each laying area is received, the redelivered tile carpet is a redelivered tile carpet with the same product number as the specified product number. The lot information has a take-out step of taking out a specified quantity for each laying area from the redelivered tile carpet satisfying a predetermined condition.

According to the above method, a tile carpet with a product number and lot information is used. As a result, for example, even if the person who laid the tile carpet and the person who removed the tile carpet are different, the lot information of the tile carpet is not lost. In each process after removal, lot information of each redelivered tile carpet can be tracked. The removed redelivered tile carpet is determined to be contaminated and screened for cleaning and reuse. In addition, the redelivered tile carpet to be washed can be narrowed down by judgment and selection. In the take-out process, the redelivered tile carpet having the specified product number and the lot information satisfying the predetermined condition is taken out in the specified quantity for each laying area. This extraction step may be performed by an operator or may be performed automatically by a machine. As a result, not only the product number but also the lot can be taken into consideration to select and take out the redelivered tile carpet for laying in each laying area. Therefore, it is possible to secure the texture of the tile carpet in the laying area in consideration of the difference in color tone due to the difference in lot in the laying area.

In the above method, the redelivered tile carpet can be carried on a trolley. In this case, the method may further include the step of transferring the redelivered tile carpet from the carriage to the cleaning line. In the sorting step, the degree of contamination of the redelivered tile carpet on the washing line can be determined and sorted. By performing the determination and sorting on the cleaning line in this way, the work efficiency is improved.

The above method may include a storage step of arranging a plurality of redelivered tile carpets with the same part number and the same lot information at the storage location. By arranging the redelivered tile carpet in the storage place in this way, the work efficiency of managing and taking out the redelivered tile carpet based on the lot information and the storage time is improved.

In the above method, it is preferable that a plurality of redelivered tile carpets having the same product number and the same lot information are collectively loaded at the storage location. For example, a plurality of redelivered tile carpets with the same part number and the same lot information can be stored in a state of being loaded on the same pallet or in a state of being put in the same box. This makes it easier to manage and take out the redelivered tile carpet considering not only the product number but also the lot, and the work efficiency is improved. Due to the above-mentioned improvement in work efficiency, it is possible to shorten the period until the redelivered tile carpet is delivered again. As a result, the effect of ensuring the texture of the tile carpet can be further enhanced.

The above method may further include a construction step of transporting the redelivered tile carpet taken out in the take-out step and laying it in the laying area. As an example, the removed redelivered tile carpet may be transported without being stored in the storage place, and may be directly transferred to the construction process of laying in the laying area. By adopting such a method, the period from removal to re-laying can be further shortened. As a result, it is possible to reduce the lot difference and enhance the effect of eliminating color unevenness and improving the sense of unity of the carpet. Alternatively, the removed redelivered tile carpet can be temporarily stored in a storage location, and then the one that meets the conditions can be taken out from the storage location, transported, and laid in the laying area. As a result, the redelivered tile carpet can be efficiently managed. As a result, it is possible to more efficiently secure the texture of the tile carpet in the laying area in consideration of the difference in color tone due to the difference in lot.

In the above method, in the take-out step, the specified quantity of redelivered tile carpet for each laying area can be taken out so that the number of lots is within a predetermined range. As a result, the variation in lots of redelivered tile carpets laid in each laying area can be kept within a predetermined range. Therefore, color unevenness due to different lots can be less likely to occur in the laying area, and the sense of unity of the laid carpet can be enhanced.

In the above method, in the take-out step, the redelivered tile carpet of the specified quantity for each laying area is taken out first from the earliest storage time so that the lot number is within a predetermined range. be able to. As a result, the lot variation of the redelivered tile carpet laid in each laying area can be kept within a predetermined range, and the one having a long storage period can be preferentially reused. Therefore, color unevenness due to differences in lots and storage periods can be less likely to occur in the laying area, and the sense of unity of the laid carpet can be enhanced. In addition, the storage period of the redelivered tile carpet can be shortened.

The method may further include a step of adding information indicating cleaning to the lot information attached to the redelivered tile carpet washed in the washing step. In this case, in the storage step and the take-out step, the redelivered tile carpet to which the lot information indicating that the item has been washed is attached has the same lot information to which the information indicating that the item has been washed is not added. The removal can be performed as a lot different from the attached redelivery tile carpet. As a result, the washed redelivered tile carpet can be treated as a different lot from the unwashed redelivered tile carpet. Therefore, in the laying area, the texture of the tile carpet in the laying area can be ensured in consideration of the difference in color tone due to the difference in lot and washing.

The method may further include a construction step of transporting the removed redelivered tile carpet and laying it in the laying area. In the construction process, tile carpets of different lots can be arranged in the central portion and the peripheral portion of the laying area. Thereby, the texture of the entire tile carpet in the laying area can be improved in consideration of the difference in color tone due to the difference in lot in the laying area.

In the above method and system, it is preferable that the tile carpet has a structure in which a surface pile tufted with a pile yarn of a dyed original fiber is laminated on a backing layer. By adopting such a configuration, it is possible to use a tile carpet that does not easily fade and is suitable for reuse.

In the take-out process of the above method, if the redelivered tile carpet whose lot information satisfies the predetermined condition cannot be taken out from the storage location by the quantity specified for each laying area, the shortage is a new product. Can be replenished with tile carpet. In this case, it is preferable that the total number of lots including the number of lots of redelivered tile carpet and the number of lots of new tile carpet is within a predetermined range.

The above method is a step of producing a recycled material by reducing the volume of a redelivered tile carpet that is determined not to be washed or reused in the sorting step, and a new tile using the recycled material. It may further have a process of producing a carpet. In this case, at least a part of the shortage when the redelivered tile carpet taken out in the take-out process is less than the quantity specified for each laying area is supplemented with the tile carpet produced using the recycled material. You may.

Tile carpets produced using recycled materials can be stored in storage areas and then transported to the laying area. As a result, the tile carpet containing the recycled material can be managed at the storage place together with the redelivered tile carpet. Therefore, the work efficiency of extracting and taking out the tile carpet that satisfies the conditions of lot information and storage time is improved. Alternatively, the tile carpet produced using the recycled material may be transported to the laying area and laid without going through the storage place. As a result, the period from production to laying can be further shortened. As a result, the effect of ensuring the texture of the tile carpet can be enhanced.

In the above system, when the extraction unit cannot extract the number of redelivered tile carpets that satisfy the conditions for which the lot information and the storage time are predetermined, the output unit is insufficient. May output information instructing it to be replenished with a new tile carpet.

According to the present invention, it is possible to secure the texture of the tile carpet in the laying area in consideration of the difference in color tone due to the difference in lot in the re-laid tile carpet.

The present embodiment relates to a method for reusing a redelivery tile carpet (hereinafter referred to as a redelivery TCP) and a redelivery TCP reuse system. FIG. 1 is a diagram showing a flow of a reuse method in the present embodiment. FIG. 2 is a diagram showing an example of an overall configuration of equipment for realizing the reuse method in the present embodiment.

The reuse method shown in FIG. 1 includes a step (S1) of removing the tile carpet laid in the facility. Here, as an example, a case where the facility is a rental office building and the resident replaces the tile carpet laid at the time of new construction of the building with his / her own tile carpet will be described. In this case, the tile carpet laid at the time of new construction of the building will be removed. During the removal process, the tile carpet is torn off the floor.

In rental office buildings, tile carpets with a single product number are often laid when one facility (building) is newly constructed. In this case, it is preferable that the tile carpets laid in each area of each floor of the facility have the same part number and the same lot. FIG. 3 is a schematic view showing an example of a part number and a lot of tile carpet laid in one facility A. The drawing is a diagram schematically showing the floor of facility A, in which the floor represents the number of floors and the area represents an area such as a store or an office where tile carpets are laid. Information on the tile carpet laid in the facility can be recorded in, for example, a redelivery TCP reuse system described later. FIG. 4 is a diagram showing a data configuration example of the tile carpet laid in the facility A shown in FIG. In the example shown in FIG. 4, the facility information, the floor, the area, the part number of the tile carpet to be laid, and the lot identification code are associated and recorded.

FIG. 5 is a diagram showing an example of the front surface and the back surface of the tile carpet 1. In the example shown in FIG. 5, the product number L1 and the lot identification code L2 are engraved on the back surface of the tile carpet 1. In FIG. 5, "Product No. 1" is engraved as the product number L1 and "Lot No. 342" is engraved as the lot identification code L2. These markings are made, for example, by laser printing. By engraving the product number and lot identification code on the back surface of the tile carpet in this way, even if the remover does not have the tile carpet information, the product number and lot of the removed tile carpet can be known. The form in which the product number and lot information are attached to the tile carpet is not limited to the example shown in FIG. For example, lot information may be printed on the back surface of the tile carpet. For example, lot information can be represented by characters, barcodes, QR codes (registered trademarks), or the like. Further, a data-readable recording medium such as an IC tag may be embedded in the tile carpet, and lot information may be recorded on the recording medium.

The tile carpet removed in S1 is transported as redelivery TCP (S2). For example, the redelivery TCP can be carried on a trolley. It is preferable to use a trolley dedicated to tile carpet.

FIG. 6A is a top view showing a configuration example of a trolley dedicated to tile carpet. FIG. 6B is a side view showing a configuration example of the dolly shown in FIG. 6A as viewed from the direction of arrow B. FIG. 6C is a side view showing a configuration example of the dolly shown in FIG. 6A as viewed from the direction of arrow C. FIG. 6D is a bottom view showing a configuration example in which the carriages shown in FIGS. 6A to 6C are viewed from below (in the direction of arrow D in FIG. 6B). FIG. 6E is a diagram showing a state in which two bogies shown in FIGS. 6A to 6D are stacked one above the other.

In the example shown in FIGS. 6A to 6C, the trolley 2 has a pedestal 23 having a surface on which the tile carpet 1 is placed, wheels 24 attached to the lower surface of the pedestal 23, and four trolleys extending upward from the four corners of the pedestal 23. It has a pillar 21. The area of the surface of the table 23 is slightly larger than the area of one tile carpet 1. That is, the size of the table 23 can be set to a size on which one tile carpet 1 can be placed. As a result, the width of the carriage 2 can be reduced, and the weight of the carriage 2 can also be reduced. Therefore, the handling (operability) of the carriage 2 is improved. The size of the target tile carpet can be, for example, 50 cm × 50 cm. A horizontal bar 22 connecting the two pillars 21 is provided at a portion corresponding to a pair of opposite sides of a quadrangle having four pillars 21 as corners. The horizontal bar 22 is not provided on the portion corresponding to the side other than the side on which the horizontal bar 22 is provided. In this way, by providing the horizontal bars 22 on the two sides and not providing the horizontal bars on the other two sides, it becomes easy to load and unload the tile carpet on the base 23. The size of the table 23 is limited to a size on which one tile carpet 1 can be placed, but is not limited to this, and may be a size on which two or four tile carpets can be placed, for example. In this case, one trolley can carry more tile carpets.

As shown in FIG. 6E, the trolley 2 has a configuration in which two trolleys 2 on which tile carpets are placed can be stacked one above the other. In this example, the heights of the four pillars 21 of the carriage 2 are the same. The upper ends of the four pillars 21 are the uppermost ends of the carriage 2. As a result, the pedestal 23 of the other trolley 2 can be placed on the four pillars 21 of one trolley 2 in a state where the mounting surface is horizontal.

As shown in FIG. 6D, a convex portion 23a in contact with the outer edge of the region corresponding to the pillar 21 is provided on the lower surface of the base 23 of the carriage 2. When the trolley 2 is placed on top of another trolley 2, the convex portion 23a of the upper trolley 2 comes into contact with the pillar 21 of the lower trolley 2. As a result, the upper trolley 2 can be prevented from shifting laterally with respect to the lower trolley 2. As a result, when moving the two trolleys 2 stacked one above the other, the upper trolley 2 is displaced from the lower trolley 2 and is less likely to fall. In the example shown in FIG. 6D, the convex portion is provided on the lower surface of the base 23, but the concave portion may be provided in the region corresponding to the pillar 21 instead of the convex portion. That is, a step may be provided on at least a part of the outer edge of the portion corresponding to the pillar 21 on the lower surface of the trolley 23 of the trolley 2.

It has been found that stacking a large number of tile carpets on top of each other can cause problems such as the tile carpet being squeezed by its own weight and causing the pile to sag (the pile remains collapsed). Therefore, it is preferable to set an upper limit on the number of tile carpets to be laminated. The height of the pillars 21 of the carriage 2 is preferably determined according to the upper limit of the number of tile carpets that can be laminated. As a result, it is possible to avoid stacking tile carpets in excess of the maximum number of stackable tiles during transportation. As a result, it is possible to suppress the settling of the pile of the tile carpet. The maximum number of stackable sheets can be, for example, 45 to 55 sheets. Correspondingly, the height of the pillar 21 from the upper surface of the base 23 can be, for example, 36 to 44 cm.

The trolley dedicated to tile carpet can be used for both in-facility transportation and inter-facility transportation. For example, a dolly can be carried by a person by stacking two trolleys on top of each other with a tile carpet placed on them. As a result, it is possible to prevent the pile from sagging due to the pressure of the plurality of tile carpets stacked on top of each other due to its own weight. It is also possible to carry a trolley with tile carpet on a truck. In this case, the truck may be configured to have a covered carrier. The space of the truck bed can be large enough to be placed on the truck bed with two trolleys stacked one above the other. As a result, damage to the tile carpet during loading and unloading can be suppressed, and the tile carpet can be efficiently transported. That is, when loading the tile carpet on the truck and when unloading it from the truck, it is not necessary to unload the tile carpet from the trolley 2 or load it on the trolley. Therefore, the number of times of loading and unloading the tile carpet is reduced. As a result, it is possible to prevent the edges of the tile carpet from being worn and deteriorated during loading and unloading. Furthermore, the work of loading and unloading is reduced, and the work efficiency is improved.

When mounting the removed redelivery TCP on the trolley 2, it is preferable to mount a plurality of redelivery TCPs having the same product number and lot on the same trolley. This is possible by adding the product number and lot information to the tile carpet. This makes it easy to collectively handle a plurality of redelivery TCPs having the same part number and the same lot in a later process.

The removed redelivered TCP is transported directly to the facility 50 having the cleaning line or via the storage location 40 and placed on the cleaning line (S3 in FIG. 1). For example, the redelivered TCP can be carried to the cleaning line in a state of being mounted on the trolley, and can be directly mounted on the cleaning line from the trolley. The cleaning line includes a transfer device such as a roller conveyor or a belt conveyor. The redelivered TCP placed on the cleaning line is transported by the transport device. The cleaning line may also have a cleaning device and / or a sorting device.

The degree of contamination is determined for the redelivered TCP on the line (S4). The degree of contamination can be determined, for example, by a person visually and based on the result of the degree of stain removal by a specific chemical. Alternatively, the computer can determine the degree of contamination based on the processing of the image obtained by photographing the redelivery TCP on the cleaning line and / or the detection result of the degree of contamination by other sensors.

The determination of the degree of contamination by a computer may be performed, for example, by measuring and quantifying the color of the surface of the tile carpet. In this case, the degree of contamination can be determined by comparing the measured surface color value of the redelivered TCP with the surface color value of the standard product. The color of the surface of the tile carpet can be obtained, for example, by measuring the tristimulus values X, Y, Z of the XYZ color system on the surface of the tile carpet. The degree of stain can be determined from the color difference value between the surface color of the surface to be measured and the surface color of the standard product obtained by the measurement.

In this example, in ascending order of the degree of contamination, three stages of determination of non-defective product determination (S5), contaminated product determination (S6), and defective product determination (S8) are made. Further, the redelivered TCP, so-called scrap, which has been cut at the laying site and has a deformed shape, is judged as a defective product (S8). For example, the above three stages can be determined according to the following criteria.
Good product judgment Can be used as it is without contamination (no contamination)
Judgment of contaminated products Although it is slightly dirty, the appearance can be restored by cleaning (light contamination)
Defective product judgment Settling and dirt are conspicuous and difficult to recover by cleaning (heavy contamination), and scraps The number of stages of the degree of contamination to be judged and the form of the judgment result are not limited to the above examples.

Depending on the determination result of S4, whether or not to clean and whether or not to reuse each redelivered TCP is selected. In this example, the redelivery TCP judged to be non-defective is not washed. The redelivered TCP that has been determined to be contaminated is washed (S7). This cleaning may include an antifouling treatment. The redelivered TCP that has been determined to be defective is neither washed nor reused. Here, "reuse" means to reuse while maintaining the form of redelivered TCP. The form (recycling) of using the material obtained by crushing or processing the redelivered TCP does not correspond to the reuse in the present invention. The redelivered TCP determined not to be reused is transported to the reprocessing factory (S9).

Redelivery TCP can be regenerated as a material for new tile carpet by processing it at a reprocessing plant. For example, redelivery TCP can be processed at a reprocessing plant and recycled as a backing material for new tile carpets.

For reprocessing, it is desirable to use a volume reduction treatment method as an example. In the volume reduction treatment method, a tile carpet is roughly crushed and the volume is reduced by a volume reduction device to obtain a string-like body. This string-like body is a high-density fiber aggregate impregnated with a thermoplastic resin and solidified. A backing layer sheet (backing material) can be obtained by cutting the string-like body, sprinkling it in a grain state on a base material, heating it, applying pressure, and integrally molding it with heat and pressure. A tile carpet is generated by laminating a carpet raw material (surface pile) on a backing layer sheet. The carpet raw machine is produced, for example, by tufting a pile on a base cloth at a raw material factory F3. In the weaving process of the carpet raw machine, the dyed pile yarn (original fiber) may be tufted on the base cloth, or the base cloth may be dyed with the pile yarn tufted. The step of attaching the carpet raw machine to the backing layer sheet to produce the tile carpet is performed, for example, in the TCP production factory F2.

As described above, the regeneration method using the volume reduction treatment includes a step of coarsely crushing the tile carpet fibers and the resin without separating them, a step of treating the coarsely crushed material with a volume reduction device, and a string obtained by the volume reduction treatment. It includes a step of cutting a state to obtain a powder or granular material, a step of hot-press molding the powder or granular material to form a backing layer of a tile carpet, and a step of laminating a surface pile on the backing layer. As a result, a new tile carpet using the recycled material can be obtained.

An example of a regeneration method using the volume reduction treatment method is described in Patent Document 2 (Japanese Unexamined Patent Publication No. 2003-41759). Further, as the volume reducing device, for example, the device disclosed in Japanese Patent Application Laid-Open No. 6-344343 can be used.

In the above volume reduction treatment method, a recycled material is produced using a high-density fiber aggregate obtained by roughly pulverizing the redelivered TCP and performing the volume reduction treatment. Therefore, all of the pile yarn, the base cloth, the glass fiber, and the fibers used to form the backing layer included in the redelivery TCP can be utilized as the high-density fiber aggregate portion. As a result, the material reuse rate is extremely high. Further, the high-density fiber aggregate obtained by the volume reduction treatment method contains 15 to 50% by volume of fibers, and when used as a lining layer of a tile carpet, its dimensional stability and strength can be enhanced. .. In this way, almost 100% of the coarsely crushed waste carpet can be used as a backing layer sheet for new tile carpet, and by using it together with reuse, it is possible to minimize the waste generated from the redelivery TCP. Become.

As shown in FIG. 1, a new tile carpet produced by using recycled material in the TCP production factory F2 may be temporarily stored in the storage location 40 and then transported to the laying facility, or may be transported to the laying facility, or the TCP production factory F2. May be transported directly to the laying facility. According to this embodiment, each redelivered TCP will be reused or recycled as a new carpet material. Therefore, the amount of waste from the redelivery TCP is reduced, which is good for the environment.

The non-defective redelivery TCP and the cleaned redelivery TCP are taken out from the cleaning line and placed in the storage location 40 (S10). At the storage location 40, it is preferable that a plurality of redelivery TCPs with the same product number and the same lot information are stored in a state of being loaded on the same pallet. For example, multiple redelivery TCPs with the same part number and the same lot may be put in a box. A plurality of boxes containing the plurality of redelivery TCPs can be stored in a state of being stacked on a pallet. In this case, it is preferable to set an upper limit of the number of boxes to be stacked on one pallet in advance. As a result, it is possible to prevent the pile from sagging due to the pressure of the plurality of redelivered TCPs stacked on top of each other due to their own weight. Further, it is preferable that each box is attached with the part number and lot information of the redelivery TCP contained in each box. As a result, redelivery TCP can be managed on a box-by-box basis, and work efficiency can be improved. For example, the product number and lot information may be printed on the outer surface of the box. The product number and lot information may be represented by characters, barcodes, QR codes (registered trademarks), or the like. Further, an IC tag for recording the product number and lot information may be attached to the box.

Information indicating that the product has been cleaned may be added to the lot information of the cleaned redelivery TCP. For example, an additional code such as a branch number may be added to the lot identification code of the redelivery TCP that has been determined to be contaminated (S6) in the contamination degree determination in S4. As a result, in the redelivery TCP of the same lot, the washed one and the unwashed one can be treated as different lots. The form of adding information indicating cleaning to the lot information is not limited to a specific one. For example, in addition to the above branch numbers, the lot information itself may be changed to a different one. The information to be added to the lot information may be printed on the back surface of the redelivery TCP in the same manner as the lot information. Alternatively, information indicating that the product has been washed can be added by printing on a pallet or box for storing the redelivered TCP or recording on an IC tag. Further, the information to be added may be changed depending on the degree of cleaning. For example, information that can distinguish between the washed redelivery TCP including the antifouling treatment and the washed redelivery TCP without the antifouling treatment may be added to the lot information.

FIG. 7 is a diagram showing an example of a shelf at the storage location 40 (stockyard) and a redelivery TCP placed on the shelf. In the example shown in FIG. 7, the shelf 4 has an area to which the product number of the redelivery TCP is assigned. For example, the product number 1 is assigned to the area of "E01" on the shelf. In the area of each product number on the shelf 4, a plurality of redelivery TCP1s of the same lot of the corresponding product numbers are loaded on the same pallet 30. That is, the plurality of redelivered TCP1s are grouped for each lot and loaded on the pallet 30. In this way, the redelivery TCP of the corresponding product number is arranged in the area assigned to each product number so that the redelivery TCP of the same lot is placed on the same pallet. Thereby, the redelivery TCP can be managed based on the product number and the lot. For example, the work efficiency when carrying out the redelivery TCP of a specific product number and lot is increased. The shelf 4 may be movable.

The information of the redelivery TCP stored in the storage location is registered in the tile carpet reuse system (S11). The tile carpet reuse system manages the stored redelivery TCP data, accepts the tile carpet request to be reused from the outside, extracts and outputs the information of the redelivery TCP that meets the request.

In addition, S10 and S11 may be performed at the same time, or S10 may be performed after S11. For example, the tile carpet reuse system accepts the input of the information of the redelivery TCP to be stored (S11), and stores it based on the received information and the information of other redelivery TCP already stored. The position of the redelivery TCP in the storage location may be determined. In this case, the redelivery TCP is carried and placed at the position determined by the tile carpet reuse system (S10).

FIG. 8 is a functional block diagram showing a configuration example of a tile carpet reuse system (hereinafter, referred to as a TCP reuse system). The TCP reuse system 5 includes a registration unit 51, a request reception unit 52, an extraction unit 53, and an output unit 54. The TCP reuse system 5 can consist of one or more computers including a processor and memory. Each function of the registration unit 51, the request reception unit 52, the extraction unit 53, and the output unit 54 of the TCP reuse system 5 can be realized by the processor executing a predetermined program. An embodiment of the present invention also includes a program for causing a computer to execute processing of each unit of a registration unit 51, a request reception unit 52, an extraction unit 53, and an output unit 54, and a recording medium on which such a program is recorded.

Further, the TCP reuse system 5 is connected to the terminals 7a and 7b, and is connected to the recording unit 6. The terminals 7a and 7b are input terminals such as a personal computer. The recording unit 6 is a data recording device accessible to the TCP reuse system 5. The recording unit 6 may be built in the TCP reuse system 5.

The registration unit 51 accepts input of information regarding the redelivery TCP placed in the storage location. For example, information regarding the redelivery TCP placed in the storage location is input to the registration unit 51 of the tile carpet reuse system 5 via the terminal 7a of the storage worker. Information on the redelivery TCP includes, for example, the part number of the used TPC stored on the shelf 4, lot information, the storage time at the storage location (for example, the delivery date when the redelivery TCP was delivered to the shelf 4), the storage position, and the like. May be included. These information can be input to the terminal 7a by, for example, a storage worker. Based on the input information, the registration unit 51 records at least the product number of the redelivery TCP, the lot information, and the information indicating the storage time in the recording unit 6 in association with each other.

FIG. 9 is a diagram showing a configuration example of redelivery TCP data recorded in the recording unit 6 by the registration unit 51. In the example shown in FIG. 9, the product number, lot number, quantity, storage time (delivery date), and storage position of the redelivery TCP in the storage location are recorded in association with each other. By recording the product number and the lot number in association with each other in this way, it is possible to manage the storage status of the redelivery TCP of the same product number and the same lot. The storage position is an example of information indicating the position of the pallet on which the redelivery TCP of the corresponding part number and lot number is placed.

In this example, as an example, the case where the information indicating the storage time is set as the delivery date will be described, but the information indicating the storage time is not limited to the delivery date. For example, other information indicating the start of storage, a storage period, or the like may be recorded as information indicating a storage time.

The input of the stored redelivery TCP data to the registration unit 51 may be performed automatically. For example, each area of the shelf 4 may be provided with a reader for IC tag data. The reader may read the data of the IC tag attached to the pallet, the box, or the redelivery TCP, add the position information, and transmit the data to the registration unit 51. The registration unit 51 receives the IC tag data read by the reader. As a result, the registration unit 51 can automatically acquire the product number, lot information, storage time information, and storage position information recorded on the IC tag. That is, it is possible to automatically associate (automatic mapping) the product number and lot information with the storage position information.

The request reception unit 52 of the TCP reuse system 5 receives input of the product number of the tile carpet to be newly laid and the quantity of the tile carpet for each laying area (see S12 in FIG. 1). The request reception unit 52 receives, for example, the request information of the tile carpet from the terminal 7b of the person in charge of ordering or the person in charge of enforcement. The required information includes, for example, the part number of the tile carpet and the quantity for each laying area. These information can be input to the terminal 7b by the person in charge of ordering, for example. As an example, the person in charge of ordering can input the number of laying sheets for each laying area at the site where the redelivery TCP is to be reused to the request reception unit 52 via the terminal 7b.

The extraction unit 53 of the TCP reuse system 5 accesses the recording unit 6 and extracts the information of the redelivery TCP according to the request received by the request reception unit 52 (see S13 in FIG. 1). The extraction unit 53 is a redelivery TCP having the same product number as the product number received by the request reception unit 52, and requests a redelivery TCP that satisfies the conditions for which the lot information and the storage time are predetermined for each laying area. Extract by quantity. For example, the extraction unit 53 sets the number of redelivery TCPs requested for each laying area in the order of longest storage period, that is, the delivery date (at the start of storage) so that the number of lots is within a predetermined range. It can be extracted in chronological order.

The redelivery TCP information extracted by the extraction unit 53 is output by the output unit 54 as information on the tile carpet for laying in the laying area. The output information may include, for example, the product number, lot information, storage position, etc. of the extracted redelivery TCP. For example, the above information is output to the terminal 7b that has transmitted the request to the request receiving unit 52.

A plurality of redelivery TCPs having the same part number but different lot numbers may be laid in one laying area. For example, if 50 redelivery TCPs with lot number 425 and 50 used CPs with lot number 210 are laid in one laying area, the total number of lot number types (ie, "lot"). "Number") becomes "2". The inventors have found that if the number of lots of redelivered TCP in one laying area becomes too large, color unevenness and the like may become noticeable. Therefore, by setting and managing the upper limit of the number of lots as a threshold value, for example, "3", it is possible to supply redelivery TCP with stable quality. In addition, in this specification, "color unevenness" due to a difference in lot means that a difference in color tone is visually recognized between tile carpets in a plurality of tile carpets laid adjacent to each other. Further, the inventors have found that by adjusting the number of lots in the laying area, the difference in color tone due to the difference in lots in the laying area can be controlled to some extent. Therefore, by setting the condition of the number of lots in the laying area when extracting the redelivery TCP, it is possible to improve or maintain the texture of the tile carpet in the laying area.

FIG. 10 is a flowchart showing an example of a process (S12, S13 in FIG. 1) of extracting and outputting a redelivery TCP for laying in one laying area. In the example shown in FIG. 10, the extraction unit 53 inputs the product number and quantity (referred to as the required product number and the required quantity) of the requested tile carpet received by the request reception unit 52 (S101).

The extraction unit 53 refers to the data of the redelivery TCP recorded in the recording unit 6, and the product number is the same as the required product number (product number = required product number), and the storage period is the longest, that is, the delivery date is the oldest. Data is extracted (S102). If the extraction is possible, the extraction unit 53 adds the extracted redelivery TCP data to the candidate TCP data (S103). When the redelivery TCP satisfying the condition cannot be extracted in S102, the output unit 54 outputs as the information of the candidate TCP that there is no redelivery TCP satisfying the request (S111). In this case, the output unit 54 may output information instructing that the shortage with respect to the required quantity is replenished with a new tile carpet.

If the quantity of the extracted candidate TCP is equal to or greater than the required quantity (YES in S104), the output unit 54 outputs the information of the candidate TCP as the tile carpet information for laying in the laying area (S111). When the quantity of the extracted candidate TCP is less than the required quantity (NO in S103) and the total number of lots of the candidate TCP is less than the threshold value (NO in S104), the extraction unit 53 is recorded in the recording unit 6. With reference to the data of the redelivery TCP, the data of the redelivery TCP having the same product number as the requested product number and the next longest storage period, that is, the next oldest delivery date is extracted (S106). The redelivery TCP data extracted in S106 is added to the candidate TCP data (S107).

When the redelivery TCP satisfying the condition in S106 is not extracted, the output unit 54 outputs the information of the candidate TCP as the information of the tile carpet for laying in the laying area (S111). In this case, the number of output candidate TCP lots has not reached the threshold. Further, the quantity of the redelivered TCP output as the candidate TCP is less than the required quantity. The amount less than the required quantity can be replenished with, for example, a new tile carpet. Multiple tile carpets to be replenished shall be of the same lot. As a result, the number of lots of tile carpet laid in the laying area becomes equal to or less than the threshold value. Further, the output unit 54 may output information instructing that the shortage with respect to the required quantity is replenished with a new tile carpet.

After S107, the extraction unit 53 repeats the determination processing of S104 and S105 until the total number of extracted candidate TCPs reaches the required quantity or the total number of lots of the extracted candidate TCPs reaches the threshold value, and the candidate TCPs of S106 and S107 are reached. Repeat the additional processing of. When the total number of candidate TCPs reaches the requested quantity (YES in S104), the output unit 54 outputs the information of the candidate TCPs at that time (S111). When the total number of lots of the candidate TCP reaches the threshold value (YES in S105), the extraction unit 53 selects the data of the redelivery TCP having the same product number as the requested product number and the next longest storage period, that is, the next oldest delivery date. Extract (S108). The extraction unit 53 replaces the extracted redelivery TCP with the used TPC of the lot with the smallest quantity among the candidate TCPs (S109). That is, the extraction unit 53 adds the newly extracted redelivery TCP to the candidate TCP, and removes the redelivery TCP of the lot having the smallest used quantity originally included in the candidate TCP from the candidate TCP. After that, S108 and S109 are repeated until the quantity of the candidate TCP reaches the required quantity (YES in S103).

When the redelivery TCP satisfying the condition cannot be extracted in S108, the extraction unit 53 removes the redelivery TCP of the lot having the smallest quantity contained in the candidate TCP from the candidate TCP (S110). As a result, the number of lots of candidate TCP is reduced by one. The output unit 54 outputs the information of the candidate TCP as the information of the tile carpet for laying in the laying area (S111). In this case, the quantity of redelivered TCP output as the candidate TCP is less than the required quantity. The amount less than the required quantity can be replenished with, for example, a new tile carpet. Multiple tile carpets to be replenished shall be of the same lot. As a result, the number of lots of tile carpet laid in the laying area becomes equal to or less than the threshold value. Further, the output unit 54 may output information instructing that the shortage with respect to the required quantity is replenished with a new tile carpet.

Further, in S110, instead of the above processing, a processing of removing the redelivery TCP of the lot having the shortest storage period, that is, the latest delivery date, included in the candidate TCP from the candidate TCP may be executed. As a result, redelivery TCP with a long storage period can be preferentially selected as a candidate and shipped.

By executing the process shown in FIG. 10 for each laying area, the number of redelivery TCPs requested for each laying area can be extracted in descending order of storage period so that the number of lots is equal to or less than the threshold value. The process shown in FIG. 10 is an example, and the process for extracting the redelivery TCP is not limited to the above example.

The redelivered TCP extracted and output by the TCP reuse system 5 is carried out from the shelf 4, that is, taken out (S14 in FIG. 1). As described above, by placing the redelivery TCP of the same product number and the same lot on the same pallet and storing it, it is possible to carry out the redelivery TCP in units of pallets in the step of S13. Therefore, the work efficiency of carrying out is high. Further, when the redelivered TCP taken out contains redelivered TCPs of different lots, an inspection step for inspecting the presence or absence of color unevenness due to the difference in lots may be provided.

The redelivered TCP taken out from the storage location is transported to the laying site (S15). The redelivery TCP can be transported from the storage location to the site in the state of being mounted on the above-mentioned trolley.

The redelivery TCP is laid in the laying area at the site (S16). FIG. 11 is a diagram for explaining an arrangement example of the tile carpet laid in the laying area. The tile carpet to be laid may include redelivery TCP and new tile carpet. In the example shown in FIG. 11, tile carpets of different lots are laid in the three areas A1, A2, and A3 in the laying area FA. That is, the lot of tile carpet laid in the areas A1 and A2 in the central part of the laying area and the lot of tile carpet laid in the peripheral part A3 of the laying area are different. By arranging the tile carpets having different lots in the central portion and the peripheral portion in this way, the subtle differences in the tile carpets due to the different lots become less noticeable. For example, it is often difficult to visually recognize color unevenness in the peripheral area due to the influence of furniture, light from windows, and the like. Therefore, as shown in FIG. 11, by laying the tile carpet of the least number of lots in the peripheral portion A3, it is possible to make the color unevenness due to the difference in lots less noticeable.

Also, each tile carpet often has a direction. Specifically, pile rows are often formed in one direction. As for the direction of each tile carpet, for example, the transport direction of the production line is indicated by an arrow on the back surface of each tile carpet. There are two ways to apply tile carpets (laying method):, for example, "flow pasting" in which multiple tile carpets are attached so that the directions of adjacent tile carpets are the same, and multiple methods of attaching tile carpets so that the directions of adjacent tile carpets are different. There is a "checkerboard paste" for pasting tile carpets. When the number of lots of tile carpets laid in one laying area increases, for example, by pasting with a checkerboard, color unevenness can be made less noticeable.

According to the present embodiment, when redelivery TCPs of a plurality of different lots are laid in one laying area and reused, the texture of the tile carpet in the laying area is determined in consideration of the difference in color tone due to the difference in lots. Can be secured. Therefore, for example, redelivery TCP removed from a plurality of areas, a plurality of floors, and a plurality of facilities can be stored and reused while maintaining quality when requested.

(Example of cleaning process)
Here, an example of the cleaning step of the redelivery TCP (S7 in FIG. 1) will be described. FIG. 12 is a diagram showing an example of a cleaning process. FIG. 13 is a top view showing a configuration example of a cleaning line used in the cleaning step shown in FIG. In the example shown in FIG. 12, the tile carpet is placed on the transport device 31a of the washing line and transported (S71). The transfer device 31a can be composed of, for example, a belt conveyor, a roller conveyor, or a combination thereof. The tile carpet is, for example, placed on a transport device with the surface facing up and transported in the horizontal direction.

The tile carpet on the transfer device is brushed and washed in the first direction (S72). The cleaning device 32a shown in FIG. 13 is used for cleaning the S72 in the first direction. The cleaning device 32a has a roller brush 33a whose rotation axis is a direction perpendicular to the transport direction. For example, cleaning in the first direction is performed by pressing the roller brush against the surface of the tile carpet on the transport device 31a with an appropriate pressure and rotating the pile in a compressed state.

For cleaning, it is desirable to use a neutral detergent solution of anion or nonion. The temperature of the neutral detergent solution is preferably a relatively high temperature of 30 ° C. or higher. The highly contaminated tile carpet can be washed, dried at 85 to 100 ° C., and then washed again. By using such a washing line, the tile carpet is dried immediately, so that the occurrence of defects such as pile discoloration can be suppressed.

Returning to FIG. 12, after cleaning in the first direction, the orientation of the tile carpet with respect to the transport direction is changed on the transport device (S73). For example, the tile carpet on the washing line may be transferred to conveyors having different transport directions, or the tile carpet may be rotated about the vertical direction on the same conveyor. In the example shown in FIG. 13, the tile carpet is washed by the cleaning device 32a and then transferred from the transport device 31a to the transport device 31b having a different transport direction. A plate 34 is provided at the end of the transport path of the transport device 31a. The tile carpet 1 transported by the transport device 31a moves to the transport device 31b by hitting the plate 34 at the end of the transport path. This changes the orientation of the tile carpet with respect to the transport direction.

Returning to FIG. 12, the tile carpet 1 turned on the washing line is brushed in a second direction different from the first direction (S74). The cleaning device 32b shown in FIG. 13 is used for cleaning the S74 in the second direction. The cleaning device 32b has a roller brush 33b whose rotation axis is a direction perpendicular to the transport direction. The cleaning in the second direction is performed, for example, by pressing the roller brush 33b against the surface of the tile carpet on the transport device and rotating it, as in the cleaning in the first direction. For example, by setting the second direction to be 90 ° different from the first direction in the surface direction, cleaning can be performed efficiently.

Returning to FIG. 12, after cleaning in the second direction, the tile carpet 1 is dehydrated (S75) and dried (S76) on the line. As described above, the cleaning steps of the present embodiment include a step of brushing the tile carpet transported on the transport path with the surface facing up in the first direction and a step of changing the orientation of the tile carpet with respect to the transport direction. And the step of cleaning the tile carpet whose orientation has been changed by brushing in a second direction different from the first direction. As a result, high-quality cleaning can be performed efficiently.

Further, the cleaning line of the present embodiment has a transfer device for transporting the tile carpet, a first cleaning device for brushing the tile carpet transported by the transfer device in the first direction, and a first cleaning device for cleaning. The direction changing means for changing the orientation of the tile carpet conveyed by the conveying device with respect to the conveying direction, and the brush in the second direction different from the first direction for the tile carpet whose orientation is changed by the orientation changing means. It is provided with a second cleaning device to be hung.

Further, a cleaning inspection process may be provided for the tile carpet after the cleaning process. In the cleaning inspection process, the tile carpet may be classified into a non-defective product and a defective product. For example, it can be classified based on the following criteria. Defective products are transported to the reprocessing plant F1 (S9 in FIG. 1).
Good product Dirt is cleanly cleaned, and it is a defective product with excellent texture and aesthetics. Dirt is not cleanly removed.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. For example, the configuration of the storage location 40, the facility 50 having a cleaning line, the reprocessing factory F1, the TCP production factory F2, and the raw material factory F3 and the means of transportation between them are not limited to the example shown in FIG. At least two of the storage place 40, the facility 50 having a cleaning line, the reprocessing plant F1, the TCP production plant F2, and the raw material plant F3 may be configured in the same building, and at least one of them is separated. It may consist of multiple buildings at the location. The transportation of the tile carpet between these facilities may be carried out using only the carriage 2 or may be carried out by using a truck. For example, FIG. 2 shows an example in which the redelivery TCP is transported by the trolley 2 between the facility 50 having the cleaning line and the storage location 40, but a truck may be used for this transportation.

In the example shown in FIG. 2, a step of producing a raw machine by tufting a pile on a base cloth and a backing step of attaching a backing layer to the raw machine are performed in different factories, that is, production lines. In this way, when the production of tile carpet includes a plurality of production lines, the lot information of the production line of the process that contributes relatively greatly to the finish of the tile carpet surface (the process of producing a livestock in this embodiment) is provided in this book. It can be lot information in the invention. The lot information in the present invention may include lot information of a plurality of production lines.

The TCP reuse system may manage data on new tile carpets and tile carpets being laid, in addition to redelivered TCP. For example, the recording unit 6 may be associated with the product number, lot information, and information (for example, production date) indicating the storage time of the new tile carpet produced in the TCP production factory F2. In this case, when the redelivery TCP satisfying the condition is insufficient, the extraction unit 53 can extract the information of the new tile carpet to make up for the shortage from the data of the recording unit 6. As a specific example, the extraction unit 53 can extract a new tile carpet having the same product number as the requested product number and the same quantity of the same lot to make up for the shortage.

In the above example, the redelivered TCP removed from the facility is once stored in the storage location 40, and then transported to another or the same facility for re-laying. The removed redelivery TCP may be transported to the facility to be re-laid without going through the storage location 40. For example, as shown in FIG. 2, the redelivery TCP may be transported from the facility 50 of the cleaning line to the facility to be re-laid without passing through the storage location 40. In this case, the information indicating the storage time can be, for example, the date of removal, the date of delivery to the cleaning line, or the like. In this way, the information indicating the storage time can be used as information for specifying the storage period after the removal.

Further, the TCP reuse system may share data and cooperate with other systems such as a new tile carpet production management system, an inventory management system, a delivery destination management system, and a recycled material production management system. ..

The TCP reuse system has a function of acquiring data from at least one of a storage shelf 4, a cleaning line, a volume reducing device of a reprocessing plant F1, a production line of a TCP production plant F2 and a raw material plant F3, and / or. It may have a function of controlling at least one of these.

For example, as described above, the shelf 4 of the storage location 40 may include an IC tag reader attached to a pallet, a box, or a tile carpet placed on the shelf 4. The TCP reuse system receives the data read by the reading device of the storage location 40, and records the product number, lot information, information indicating the storage time, storage position, etc. of the redelivered TCP in the storage location 40 in the recording unit 6. can do.

Further, the shelf 4 may be provided with an automatic loading / unloading device for loading and unloading pallets, boxes or tile carpets on the shelves. In this case, the TCP reuse system can control the automatic loading / unloading device to unload the redelivered TCP extracted by the extraction unit 53 from the shelf 4. Alternatively, the automatic loading / unloading device can be controlled so that the redelivered TCP is placed at the position determined by the TCP reuse system.

Further, the TCP reuse system may be able to communicate with a sensor for measuring the color of the surface of the redelivered TCP in the transfer device of the cleaning line, and a sorting device. In this case, the TCP reuse system may execute the contamination degree determination process of the redelivered TCP based on the information from the sensor, control the sorting device, and automatically perform the sorting based on the contamination degree determination result. it can. In this way, for example, S4 to S14 shown in FIG. 1 can be automatically processed by the computer of the TCP utilization system. It is also possible to automate a part of S4 to S14.
