Description

The present invention relates to a feather product recycling system for recycling feather products such as a duvet, a feather product recycling method, and a store equipped with a feather product recycling system.

Feathers have excellent hygroscopicity and heat retention, and are lightweight, so they are used in various products such as duvets, pillows, and cushions. A feather product using feathers as a filler is used for many years, so that the side fabric containing the feathers and the feathers filled therein become dirty and hurt, and the original performance cannot be exhibited.
Therefore, it is known that the feather product is regenerated by dismantling the feather product, washing and drying the feather, and filling the treated feather in a new side fabric.
Patent Literature 1 describes a feather processing device that dismantles a feather product and regenerates the taken-out feathers. This feather treatment device is equipped with a stirring device that stirs the feathers and performs the processing necessary for regeneration. By stirring the feathers in the stirrer, the aggregated feathers are dispersed, and the dust mixed in the feathers is separated from the feathers and removed. In addition, the feather treatment device sequentially introduces high-temperature steam, ozone, and hot air into the stirrer according to the treatment stage, and spreads steam, ozone, and hot air to each feather while stirring the feathers. The feathers are subjected to sterilization treatment with high-temperature steam, deodorant sterilization treatment with ozone, and drying treatment with hot air.

JP, 2001-17754, A

In Patent Document 1, since the feathers taken out from the side cloth are directly introduced into the stirring device, there is a problem that the feathers adhere to each part in the stirring device. Therefore, cleaning of the stirring device becomes very complicated. Further, in the case where the feathers relating to the feather products received from different customers are continuously regenerated, there is a possibility that the feathers that cannot be removed by cleaning may be separated and mixed during the treatment of the next feathers.
The present invention has been made in view of the above circumstances, and prevents the mixing of feathers derived from different feather products during the regeneration processing of feather products, and gives the customer a sense of security for the regeneration processing of feather products. With the goal.

In order to solve the above problems, the present invention provides a transfer means for transferring feathers extracted from a feather product to a treatment bag, a cleaning/dehydration means for cleaning/dehydrating the feathers together with the processing bag, and the cleaning. The primary drying means for primary drying the dehydrated feathers together with the treatment bag, the secondary drying means for secondary drying the primary dried feathers for the treatment bag, and the secondary drying means. Waste heat induction piping for guiding waste heat to the primary drying means.

Advantageous Effects of Invention According to the present invention, it is possible to prevent mixing of feathers derived from different feather products during the regeneration treatment of feather products, and to give a customer a sense of security regarding the regeneration treatment of feather products.

[Regeneration system for down products]
FIG. 1 is a schematic diagram illustrating a feather product recycling system according to an embodiment of the present invention. The feather product recycling system according to the present embodiment includes a pre-drying step and a main drying step in which each processing relating to the recycling of the feather product is performed for each processing bag (with the feathers stored in the processing bag), and the step of drying the feathers. It is characterized in that the waste heat discharged during the main drying is used for pre-drying after being separated into steps. Hereinafter, the regeneration treatment of the feather product according to the present invention will be described based on the example of the duvet, but the present invention can be applied to a feather product other than the duvet, such as a pillow or a cushion in which the feather is used as the filling material. is there.
The feather product recycling system 1 dismantles a duvet A (feather product: see FIG. 3), takes out the feathers filled in the duvet, and stores them in the treatment bag B. The dismantling unit 10 cleans and dehydrates the feathers. A washing machine (washing/dehydrating means) 50, a drying section (drying means) 60 for drying feathers, and a filling section 90 for filling the side fabric C for a new duvet with feathers are provided.

<Dismantling section>
The dismantling unit 10 dismantles the duvet to take out the feathers, a recovery chamber 31 that recovers the feathers taken out from the duvet by the dismantling, and collects dust separated from the feathers in the recovery chamber 31. A dismantling dust collecting chamber (dust removing means in a dismantling/transferring process) 41. The dismantling chamber 11 and the recovery chamber 31 are connected via a recovery pipe (transfer means) 25, and the recovery chamber 31 and the dismantled dust collecting chamber 41 are connected via a dust removing pipe 35.
In the following description, of the side surfaces of the dismantling chamber 11, the side surface facing the worker during the dismantling operation of the duvet will be described as the front surface. Further, the direction of gravity will be described as the height direction, the direction along the shoulder width direction of the worker during the dismantling work of the duvet as the width direction, and the direction orthogonal to both directions as the depth direction (front-back direction when viewed from the worker).

The dismantling chamber 11 includes a substantially box-shaped housing 15 that forms a dismantling space 13 that is a space for disassembling a duvet, a dismantling hanger 17 installed in the dismantling space 13 in a substantially horizontal posture, and a dismantling hanger 17. A transport path (transport means) 19 that is disposed below and transports the feathers taken out from the duvet toward the recovery chamber 31.
An opening 21 is formed in the upper front part of the housing 15, and the upper part of the dismantling space 13 communicates with the external space through the opening 21.

The dismantling hanger 17 is a means for suspending a duvet to be dismantled in a two-fold posture, and both ends (one end 17a, the other end 17b) in the axial direction are opposed to the inner surface 15a in the width direction of the dismantling space 13. , 15b, respectively.
One end 17a in the axial direction of the disassembly hanger 17 is swingably supported in the depth direction (the direction of arrow D in the drawing) by a hinge portion attached to the inner side surface 15a. Further, the other end portion 17b in the axial direction of the disassembly hanger 17 is detachably locked to a locking member attached to the inner side surface 15b. The dismantling hanger 17 engages the other end 17b in a pulling-out position (shown by a broken line) in which the other end 17b is drawn out of the opening 21 to the outside of the dismantling space 13, and the other end 17b is engaged with a locking member provided on the inner side surface 15b. It swings in the depth direction (the direction of arrow D in the drawing) between the stopped posture (shown by the solid line). By displacing the dismantling hanger 17 in the pulled-out posture, the duvet can be hung on the dismantling hanger 17 outside the dismantling space 13, so that the hanging operation becomes easy. When the dismantling hanger 17 is displaced to the locked posture, the entire down duvet is located in the dismantling space 13, so that it is possible to prevent the feathers taken out by the dismantling work from scattering from the opening 21 to the outside.

The transport path 19 is arranged at the bottom of the dismantling space 13. The transport path 19 shown in this example is formed by an inclined surface that is inclined so that one end side in the width direction of the disassembly chamber 11 is high and the other end side is low. A recovery port (transfer means) 23 communicating with the recovery pipe 25 is formed through the inner surface 15b located at the downstream end of the transport path 19. The conveyance path 19 guides the feathers, which have been taken out of the duvet and dropped, toward the recovery port 23 by using gravity. The inclination direction of the transport path 19 and the shape thereof can be freely set according to the formation position of the recovery port 23 and the like.
The feathers transported through the transport path 19 are transported to the recovery chamber 31 via the recovery port 23 and the recovery pipe 25.

The recovery chamber 31 has a box shape having a hollow portion capable of accommodating the processing bag B therein, and includes a door 33 for opening and closing the hollow portion on one side surface (for example, front surface).
The recovery pipe 25 communicates with the inside of the recovery chamber 31 at the downstream end. The downstream end of the recovery pipe 25 is exposed inside the recovery chamber 31, and the processing bag B is detachably attached to the downstream end of the recovery pipe 25 by using a fastening band or the like. The processing bag B is attached to the recovery pipe 25 so that no gap is generated so that all the feathers can be recovered without leakage. In this example, since the downstream end of the recovery pipe 25 is connected to the ceiling of the recovery chamber 31, the processing bag B is suspended in the recovery chamber 31.

The processing bag B prohibits passage of feathers and small feathers, but has a mesh-like material with a large number of holes that allow passage of finer dust than the feathers mixed in the feathers and dirt attached to the feathers. (Or a porous material). The dust includes dust, dust, mite feces and carcasses, and feather dust (down fiber and powder). The processing bag B functions as a filter that separates unnecessary dust from the feathers. The treatment bag B is made of a woven fabric having a density that prevents feathers and small feathers mixed in the feathers from coming out. The treatment bag B has a predetermined air permeability such that the feathers can be washed and dried with the feathers housed inside.
A dust removing pipe 35 that conveys the dust that has passed through the processing bag B to the dismantling dust collecting chamber 41 is connected to an appropriate place (the lower portion of the side surface in this example) of the collecting chamber 31.
The door 33 that opens and closes the recovery chamber 31 has such a degree that the inside of the recovery chamber 31 can be maintained in a negative pressure state (atmospheric pressure lower than atmospheric pressure) when the air in the recovery chamber 31 is sucked from the dust removing pipe 35. It only needs to have a hermeticity. In other words, the door 33 only needs to have a sealing property such that an air flow capable of transporting feathers into the processing bag B can be created in the recovery pipe 25.

The dismantling dust collecting chamber 41 is a box-like shape having a hollow portion inside which a dust collecting bag (dust removing means in the disassembling/transferring process) 45 can be housed, and a door 43 for opening and closing the hollow portion on one side surface (for example, front surface). Equipped with.
The dust removing pipe 35 communicates with the inside of the demolition dust collecting chamber 41 at the downstream end. The downstream end of the dust removing pipe 35 is exposed inside the dismantling dust collecting chamber 41, and the dust collecting bag 45 is detachably attached to the downstream end of the dust removing pipe 35 by using a tightening band or the like. The dust-collecting bag 45 is attached to the dust-removing pipe 35 so that no space is generated so that all dust can be collected without leakage. In this example, since the downstream end of the dust removing pipe 35 is connected to the ceiling of the dismantling dust collecting chamber 41, the dust collecting bag 45 is suspended in the dismantling dust collecting chamber 41.

The dust collecting bag 45 is made of a mesh-like material (or a porous material) having a large number of holes that allow passage of air while prohibiting passage of dust. The dust collection bag 45 functions as a filter that removes dust in the air sucked from the collection chamber 31. For the dust bag 45, a woven fabric having a predetermined density can be used. Since the dust collecting bag 45 captures the dust that has passed through the processing bag B and creates clean air, the hole of the dust collecting bag 45 is smaller than the hole of the processing bag B. In other words, the dust collecting bag 45 has finer eyes than the processing bag B. The clean air that has passed through the dust collecting bag 45 is discharged to the outside (in the atmosphere) from an exhaust port (exhaust pipe 47) provided at an appropriate position of the dismantling dust collecting chamber 41.
A blower (suction blower) 37 that sucks the air in the collection chamber 31 and introduces it into the disassembly dust collection chamber 41 is installed at an appropriate position in the middle of the dust removal pipe 35. In this example, the feather is transferred from the recovery port 23 of the dismantling chamber 11 to the processing bag B through the recovery pipe 25 by using the suction force generated by the blower 37, and also passes through the processing bag B in the recovery chamber 31. Remove dust.

Here, the inner diameter of the exhaust pipe 47 is determined based on the air volume of the blower 37. The inner diameter of the exhaust pipe 47 is set so that the amount of air discharged from the exhaust pipe 47 per unit time is the same amount (equivalent) to the amount of air introduced from the dust removing pipe 35 per unit time. Is desirable. When set in this way, the dismantling and dust collecting chamber 41 does not need to be specially sealed. At least the inner diameter of the exhaust pipe 47 is preferably set so as to have an exhaust capacity such that the inside of the dismantling and dust collecting chamber 41 does not become an environment having a pressure higher than atmospheric pressure.
When the collection of all the feathers taken out from the duvet is completed, the worker removes the treatment bag B from the collection pipe 25, closes the mouth of the treatment bag B, and moves the treatment bag B to the washing machine 50.

<Washing machine>
The washing machine 50 removes various stains attached to the feathers and dewaters the washed feathers. The feathers are washed for each processing bag B (in the state of being contained in the processing bag B). In this example, in order to avoid damage to the feathers, as a rule, only the water or lukewarm water is used to wash the feathers. However, when it is determined that the stains and odors attached to the feathers cannot be removed by water or lukewarm water alone, the feathers are washed with a washing liquid prepared by adding neutral detergent to water or lukewarm water.
The feathers that have been washed and dehydrated in the washing machine 50 are moved to the next-stage drying unit 60 while being kept in the processing bag B.

<Drying part>
The drying unit 60 includes a pre-drying chamber (primary drying means) 61 for semi-drying the feathers, a main dryer (secondary drying means) 69, 69 for completely drying the semi-dried feathers, and a main dryer 69, Waste heat recovery pipes (waste heat induction pipes) 71 (71a, 71b) for recovering waste heat from 69, and a dry dust collecting chamber (dust removing means in a drying process) 73 for removing dust contained in the recovered waste heat 73 And a waste heat supply pipe (waste heat induction pipe) 79 for supplying the waste heat after dust collection to the pre-drying chamber 61.
The pre-drying chamber 61 is a device for semi-drying the feathers that have been washed and dehydrated together with the treatment bag B. The pre-drying chamber 61 includes a door 63 that opens and closes the pre-drying chamber 61, a drying hanger 65 installed in the pre-drying chamber 61, and the like. The pre-drying chamber 61 has a size such that an operator can enter and work inside the pre-drying chamber 61. The worker enters and leaves the pre-drying chamber 61 through the door 63.

The drying hanger 65 is a means for suspending the processing bag B in a roughly folded posture, and is composed of, for example, a long bar. The drying hanger 65 is such that the lower ends of the processing bags B are separated from each other when the processing bags B are hung in a double weave posture (for example, an inverted V-shaped posture or an inverted U-shaped posture). It is desirable that the processing bag B be provided with a configuration that allows the processing bag B to be hung. For example, one dry hanger 65 can include two or more long rods that are arranged in parallel at a predetermined distance.
The illustrated pre-drying chamber 61 is provided with one drying hanger 65 made of one long bar, and one processing bag B can be hung from the drying hanger 65. The chamber 61 may have a structure capable of suspending two or more processing bags B at the same time in the pre-drying chamber 61. For example, one dry hanger 65 has a configuration capable of suspending a plurality of treatment bags B with respect to the dry hanger 65, that is, a configuration capable of suspending the treatment bags B at different positions in the longitudinal direction. May be. Alternatively, the pre-drying chamber 61 may include two or more (two or more sets) of drying hangers 65, and a configuration in which a plurality of processing bags B can be hung on each of the drying hangers 65.

A blower fan 66 may be installed in the pre-drying chamber 61 to blow the air in the pre-drying chamber 61 toward the processing bag B. For example, the blower fan 66 is a position where the air can be blown between the opposite lower end portions (between the opposite side surfaces) of the one processing bag B that is suspended in a two-fold posture, and is located at the floor of the pre-drying chamber 61. It can be installed on the surface or in a suitable place under the pre-drying chamber. By installing the blower fan 66 in the pre-drying chamber 61, the flow of air is promoted in the portion of the surface of the processing bag B where air is likely to stay, and the air having a flow is spread over the entire surface of the processing bag B. Is possible. By doing so, the drying time of the feathers stored in the treatment bag B can be shortened as a whole. Particularly, when the temperature of the waste heat introduced from the main dryer 69 is relatively low (for example, when electricity is used instead of gas as the heat source of the main dryer 69), the blower fan 66 is installed. Is very effective. It should be noted that a guide unit such as a pipe for guiding the air to an arbitrary position and direction may be optionally provided so that the air with the flow generated by the blower fan 66 can be blown to the arbitrary position of the processing bag B. The blower fan 66 may be a device that simply stirs the air in the pre-drying chamber 61.

A waste heat supply pipe 79 is connected to an appropriate place of the pre-drying chamber 61 (a lower part of the pre-drying chamber 61 in this example), and waste heat from the main dryer 69 is introduced into the pre-drying chamber 61. Further, the pre-drying chamber 61 is provided with a heat radiating port (heat radiating pipe 67) for radiating the waste heat used for pre-drying to the outside (into the atmosphere) in another suitable place (ceiling in this example).
Here, the inner diameter of the heat radiation pipe 67 is determined based on the air volume of the blower and the air volume of the blower 72 provided in the main dryers 69, 69. The inner diameter of the heat radiation pipe 67 is set so that the amount of air discharged from the heat radiation pipe 67 per unit time is the same amount (equal) to the amount of air introduced from the waste heat supply pipe 79 per unit time. It is desirable to be done. When set in this way, the pre-drying chamber 61 does not need to be specially sealed. It is desirable that at least the inner diameter of the heat radiation pipe 67 is set so that the predrying chamber 61 has an exhaust capacity such that the predrying chamber 61 does not have a high-pressure environment higher than the atmospheric pressure.

The dryer 69 is a well-known dryer including a heating unit that heats air to generate hot air. Gas, electricity, or steam is generally used as the heat source. The main dryer 69 fully dry the feathers together with the treatment bag B. The dryer 69 is a so-called drum type dryer, and while the processing bag B is rotated, hot air is spread over the entire feathers to completely dry the feathers. The dryer 69 dries the feathers with hot air of about 70 degrees. In this example, waste heat from the main dryer 69, which is close to 70 degrees, is introduced into the pre-drying chamber 61 and reused. The hot exhaust gas discharged from the main dryer 69 is first introduced into the dry dust collecting chamber 73 through the waste heat recovery pipe 71.

The dry dust collection chamber 73 is means for removing dust contained in the high-temperature exhaust gas discharged from the main dryer 69. Its structure is similar to that of the dismantling and dust collecting chamber 41. That is, the dry dust collecting chamber 73 has a box shape having a hollow portion inside which a dust collecting bag (dust removing means in the drying process) 77 can be housed, and a door 75 for opening and closing the hollow portion on one side surface (for example, front surface). Equipped with.
The waste heat recovery pipe 71 communicates with the inside of the dry dust collecting chamber 73 at the downstream end. Further, the downstream end of the waste heat recovery pipe 71 is exposed inside the dry dust collecting chamber 73, and the downstream end of the waste heat recovery pipe 71 can be detachably attached with a dust collecting bag 77 by using a tightening band or the like. Attached to. The dust collecting bag 77 is attached to the waste heat recovery pipe 71 so that no gap is generated so that all the dust can be collected without leakage. In this example, since the downstream end of the waste heat recovery pipe 71 is connected to the ceiling of the dry dust collecting chamber 73, the dust collecting bag 77 is suspended in the dry dust collecting chamber 73.
The waste heat recovery pipe 71 shown in this example is configured to include waste heat recovery pipes 71a, 71a arranged on the upstream side and a waste heat recovery pipe 71b arranged on the downstream side. The upstream ends of the waste heat recovery pipes 71a and 71a are connected to the dryers 69 and 69, respectively, and the waste heat recovery pipe 71b is connected to the waste heat recovery pipes 71a and 71a on the upstream side and the drying end is connected to the downstream end. It communicates with the inside of the dust chamber 73. The high-temperature exhaust gases discharged from the respective main dryers 69, 69 and flowing through the waste heat recovery pipes 71a, 71a join together in the waste heat recovery pipe 71b.

The dust collecting bag 77 is made of a mesh-like material (or a porous material) having a large number of holes that allow passage of air but prohibit passage of dust. The dust collecting bag 77 functions as a filter that removes dust in the waste heat introduced from the main dryers 69, 69. For the dust collecting bag 77, a woven fabric having a predetermined density can be used. Since the dust collecting bag 77 captures the dust that has passed through the processing bag B during the main drying and creates clean air, the hole of the dust collecting bag 77 is smaller than the hole of the processing bag B. In other words, the dust collecting bag 77 has finer eyes than the processing bag B. The clean, high-temperature exhaust gas that has passed through the dust collecting bag 77 is introduced into the pre-drying chamber 61 from a waste heat supply pipe 79 connected to an appropriate place (the ceiling portion in this example) of the dry dust collecting chamber 73. Since clean waste heat after dust collection is introduced into the pre-drying chamber 61, it is possible to prevent dust from adhering to the surface of the processing bag B in the pre-drying process. The pre-drying chamber 61 is supplied with drying air having a relatively high temperature (for example, about 65 degrees).
Here, the inner diameter of the waste heat supply pipe 79 is determined based on the air volume of the blower and the air volume of the blower 72 provided in the main dryers 69, 69. As for the inner diameter of the waste heat supply pipe 79, the amount of air discharged from the waste heat supply pipe 79 per unit time is equal to (equal to) the amount of air introduced from the waste heat recovery pipe 71 per unit time. It is desirable to set so that When set in this way, the dry dust collecting chamber 73 does not need special airtightness. At least the inner diameter of the waste heat supply pipe 79 is preferably set so that the dry dust collecting chamber 73 has an exhaust capacity that does not create an environment higher than atmospheric pressure.

A blower 72 for sending the exhaust gas discharged from the main dryer 69 toward the downstream side may be additionally provided at an appropriate position in the middle portion of the waste heat recovery pipe 71. When a plurality of main dryers 69, 69 are provided, it is efficient to arrange the blower 72 in the waste heat recovery pipe 71b after the exhaust air from the main dryers 69, 69 merges. The blower 72 always forces the fresh exhaust gas into the pre-drying chamber 61 by creating an exhaust gas flow of a predetermined speed. The blower 72 may be provided at an appropriate position on the waste heat supply pipe 79 or may be provided at an appropriate position on the heat radiation pipe 67. Further, the blower 72 can be installed in all of the waste heat recovery pipe 71, the waste heat supply pipe 79, the heat radiation pipe 67, or selectively with respect to each pipe.

<Filling part>
The filling unit 90 includes a weighing machine 91 for weighing the weight of the feathers, and a filling machine (filling means) 93 for filling the side fabric C for the new duvet with the feathers. In the filling section 90, the feathers after drying are weighed by the weighing machine 91, new feathers in an amount corresponding to the shortage are added, and the new side cloth C is filled with feathers by the filling machine 93.
The weight of the feathers after the main drying is measured by the measuring device 91 together with the processing bag B (in the state where the processing bag B is still contained). Here, "weighing the feathers together with the treatment bag B" means that the total amount of the feathers is weighed without taking out the feathers from the treatment bag B. If the feathers are weighed together with the processing bag B, the feathers do not adhere to the weighing container (or weighing pan) provided in the weighing device 91, so that it is possible to prevent the feathers from coming from different duvets from being mixed and to clean the weighing container. It will be easy.

By measuring the feathers after the main drying, the amount of feathers insufficient with respect to the total amount of the feathers to be filled in the new side cloth C is calculated. The total amount of feathers to be filled in the new side cloth C is adjusted by adding new feathers in an amount corresponding to the shortfall to the feathers after the main drying.
The filling machine 93 uniformly mixes the feathers after the main drying with the newly added feathers, and blows the feathers out of the nozzle. The operator uses the filling machine 93 to fill each square of the side cloth C with feathers.
Finally, the blow-off port of the feather provided on the new side fabric C is sewn to complete the regeneration process of the duvet, that is, the tailoring.

<Feather management>
In the feather product recycling system 1, a plurality of duvets are simultaneously recycled in parallel. Therefore, in the feather product recycling system 1, a plurality of processing bags B, B... Are used at the same time. Each processing bag B is given a unique reference number (identifier) that is distinguished from other processing bags B.
The reference number attached to each processing bag is linked to the information (name, telephone number, etc.) that identifies the customer who requested the duvet's recycling processing and the details of the request from the customer (hereinafter referred to as "customer information"). Be managed.
For this management, for example, the customer information and reference number are entered in the order receipt, and the identification tag with the reference number is attached to each of the duvet, the processing bag, and the new side cloth C selected by the customer. It is done by doing.
In this way, by managing the serial number attached to the treatment bag and the customer information in association with each other, and performing each treatment related to feather reproduction for each treatment bag, it is confused with the mixture of feathers derived from feather products of different customers. Can be prevented.

<Process flow>
Hereinafter, each process in the feather product reproducing system will be described based on a flowchart. FIG. 2 is a flowchart showing the flow of processing in the feather product recycling system.

In step S1, the worker receives the duvet from the customer. At this time, the worker associates the customer information with the reference number (an example of an identifier) used during the feather processing. For example, the customer information and the reference number are written on the order receipt, and the duvet, the processing bag, and the new side cloth C selected by the customer are each attached with a tag indicating the reference number.
In step S2, the worker confirms the state of the duvet and determines the work policy of each process.
In step S3, the worker disassembles the duvet and stores the taken out feather in the treatment bag. That is, as shown in FIGS. 1 and 3, the worker suspends the duvet A on the dismantling hanger 17 of the dismantling chamber 11, and collects the processing bag B having the same reference number as the duvet A in the collection chamber 31. Install inside. Further, the operator turns on the switch of the blower 37 to start the operation of the blower 37. The operator cuts the side cloth of the down duvet A with a cutter or the like, opens each square, and sequentially takes out the down. The taken-out feathers fall into the transport path 19 and are transferred from the recovery port 23 to the processing bag B through the recovery pipe 25 by the guidance of the operator and the suction force of the blower 37.
When the feathers are collected in the treatment bag B, dust mixed in the feathers passes through the treatment bag B. These dusts are collected in the dust collecting bag 45 in the dismantling dust collecting chamber 41 through the blower 37 and the dust removing pipe 35. Further, the air that has passed through the dust bag 45 is discharged into the atmosphere through the exhaust pipe 47.

In step S4, the feathers are washed and dehydrated together with the treatment bag B. That is, the worker removes the feathered treatment bag B from the collection chamber 31, closes the mouth of the treatment bag B, and then moves the treatment bag B to the washing machine 50. The worker turns on the switch of the washing machine 50 to wash and dehydrate the feathers by the washing machine 50.
In step S5, the feathers are pre-dried together with the treatment bag B. That is, the worker takes out the processing bag B after the completion of the dehydration from the washing machine 50 and moves it to the pre-drying chamber 61. The operator suspends the processing bag B on the drying hanger 65 in the pre-drying chamber 61. Waste heat from the main dryer 69 is introduced into the pre-drying chamber 61, and this waste heat is used to remove a part of water from the feathers in advance before the main drying. When the main dryer 69 is not operating, the pre-drying process of step S5 is omitted and the process proceeds to the main drying process of step S6.
In step S6, the feathers are fully dried together with the treatment bag B. That is, the operator takes out the processing bag B after the pre-drying from the pre-drying chamber 61 and moves it to the main dryer 69.

The main dryer 69 is a rotary drum type dryer, and in the main drying step, the processing bag B is dried with high-temperature hot air while rotating in the main dryer 69. The dust that has passed through the processing bag B in the main drying step is collected in the dust collecting bag 77 via the waste heat recovery pipe 71. Since clean waste heat after dust collection is introduced into the pre-drying chamber 61, dust can be prevented from adhering to the surface of the processing bag B in the pre-drying process.
When the pre-drying step of step S5 is omitted, in order to completely dry the feathers, the main drying time is set longer than the main drying time set for the feathers that have gone through the pre-drying step.

In step S7, the feather is weighed together with the treatment bag B by the weighing device 91.
In step S8, new feathers are added to the treatment bag B to adjust the total weight of the feathers so that the new side cloth C has the amount of feathers to be filled.
In step S9, the new side cloth C is filled with feathers. That is, the operator prepares a new side fabric C having the same reference number as the reference number attached to the processing bag B, and uses the filling machine 93 to provide a required amount of feathers on each square of the side fabric C. In sequence. Further, after the filling of the feathers is completed, the operator sew the feather blow openings provided on the side cloth C to complete the re-tailoring of the duvet.
In step S10, the duvet after the reproduction is delivered to the customer.

<Effect>
In this example, since each step of regenerating the duvet, that is, washing, dehydration, drying, and weighing is performed for each processing bag, the feathers taken out from one duvet and the feathers taken out from another duvet. And do not mix.
Further, the cost for cleaning each device constituting the feather product recycling system is reduced. If the feathers are taken out of the treatment bag and dried with this dryer, a large-scale cleaning work is required to remove the feathers adhering to the drying drum. Complete removal is difficult. This also applies to a washing machine.
In this way, in this example, since each step of regenerating the duvet is carried out for each treatment bag, it is possible to prevent the feathers taken out from different duvets from being mixed with each other and to reduce the maintenance cost of each device. You can

Since it takes time to dry feathers containing water, there is a large difference between the time required for washing/dehydrating and the time required for drying feathers. Particularly, in the present embodiment in which the feather regenerating process is performed for each processing bag, the drying time tends to increase. It is necessary to allocate a plurality of (for example, three) dryers to one washing machine in order to continuously perform the reproduction processing of a plurality of duvets without delaying each work. .. However, if a drying device having a heating source is adopted for all of the drying devices, the facility introduction cost increases and a large amount of fuel is required, so that the fuel cost and the environmental load increase. In the present embodiment, since waste heat at the time of main drying is used for pre-drying, it is possible to shorten the main drying time, save the fuel required for drying the feathers, and reduce the environmental load.
