Description

  The present invention relates to a feather product regenerating system for regenerating a feather product such as a duvet, a feather product regenerating method, and a store including a feather product regenerating system.

Feathers are used in various products such as futons, pillows, cushions, etc. because they are excellent in hygroscopicity and heat retention and are lightweight. A feather product using feathers as a filler material has been used for many years, so that the side fabric containing the feathers and the feathers filled therein are soiled and painful, and cannot exhibit their original performance.
Therefore, it has been known that the feather product is dismantled, and the feather taken out is washed and dried, and the treated feather is filled in a new side cloth to regenerate the feather product.
Patent Literature 1 discloses a feather processing apparatus that regenerates feathers that are taken out of a feather product by being disassembled. The feather processing apparatus includes a stirrer that stirs the feathers and performs a process required for regeneration. By stirring the feathers in the stirrer, the aggregated feathers are dispersed, and dust mixed in the feathers is separated from the feathers and removed. In addition, the feather processing device sequentially introduces high-temperature steam, ozone, and hot air into the stirring device according to the processing stage, and distributes steam, ozone, and hot air to each feather while stirring the feather. The feathers are subjected to a sterilization treatment with high-temperature steam, a deodorization and sterilization treatment with ozone, and a drying treatment with hot air.

JP 2001-17754 A

In Patent Literature 1, since the feathers taken out of the side dough are directly introduced into the stirring device, there is a problem that the feathers adhere to each part in the stirring device. For this reason, cleaning of the stirring device becomes very complicated. Further, in the case where the feather regenerating process for feather products received from different customers is continuously performed, feathers that cannot be removed by cleaning may be separated and mixed during processing of the next feather.
The present invention has been made in view of the above-described circumstances, and prevents mixing of feathers derived from different feather products during the feather product regeneration process, and provides customers with a sense of security for the feather product regeneration process. With the goal.

In order to solve the above problems, the present invention includes a transfer means for transferring the feather taken out of the feather product disposal bag, and washing and dewatering means for the disposal bag for each washing and dehydrating the feathers, the processing A primary hanger for drying the washed and dehydrated feathers together with the processing bags, and a secondary drying unit for secondary drying the primary dried feathers together with the processing bags. Means, and a waste heat induction pipe for guiding waste heat discharged from the secondary drying means to the primary drying means.

  Advantageous Effects of Invention According to the present invention, it is possible to prevent feathers derived from different feather products from being mixed during a feather product regeneration process, and to give a customer a sense of security in the feather product regeneration process.

  Hereinafter, the present invention will be described in detail using embodiments shown in the drawings. However, the components, types, combinations, shapes, relative arrangements, and the like described in this embodiment are not merely intended to limit the scope of the present invention but are merely illustrative examples unless otherwise specified. .

[Feather product reproduction system]
FIG. 1 is a schematic diagram illustrating a feather product regeneration system according to one embodiment of the present invention. The feather product regeneration system according to the present embodiment includes a pre-drying process and a main drying process in which each process related to feather product regeneration is performed for each processing bag (while the feathers are stored in the processing bag), and the process of drying the feathers. It is characterized in that waste heat discharged during main drying is used for predrying separately from the process. Hereinafter, the regeneration treatment of the down product according to the present invention will be described based on an example of a duvet, but the present invention is also applicable to down products other than the duvet, such as pillows and cushions using down as a filling material. is there.
The reproductive system 1 for a feather product dismantles the duvet A (feather product: see FIG. 3), takes out the feathers filled in the duvet, and stores it in the disassembly section 10 to be stored in the processing bag B. A washing machine (washing / dehydrating means) 50, a drying section (drying means) 60 for drying down, and a filling section 90 for filling the down with the side fabric C for a new duvet.

<Dismantling part>
The disassembly section 10 dismantles the down duvet to take out the down, a disassembly chamber 11 for collecting the down taken out of the down duvet by the disassembly, and collects dust separated from the down in the collection chamber 31. Dismantling dust collection chamber (dust removing means in dismantling / transfer process) 41; The disassembly chamber 11 and the collection chamber 31 are connected via a collection pipe (transfer means) 25, and the collection chamber 31 and the disassembly dust collection chamber 41 are connected via a dust removal pipe 35.
In the following description, among the side surfaces of the disassembly room 11, the side surface facing the worker during the disassembly operation of the duvet will be described as the front surface. The direction of gravity will be described as the height direction, the direction along the shoulder width direction of the worker during the work of dismantling the duvet will be referred to as the width direction, and the direction perpendicular to both directions will be referred to as the depth direction (front-back direction as viewed from the worker).

The dismantling chamber 11 includes a roughly box-shaped housing 15 that forms a dismantling space 13 that is a space for dismantling the duvet, a dismantling hanger 17 that is installed in the dismantling space 13 in a substantially horizontal posture, and a dismantling hanger 17. And a transport path (transfer means) 19 disposed below and transporting the feathers taken out of the duvet to the collection chamber 31.
An opening 21 is formed in the upper front part of the housing 15, and the upper part of the disassembly space 13 communicates with the external space via the opening 21.

The dismantling hanger 17 is a means for suspending the duvet to be dismantled in a folded state in two positions, and has both ends (one end 17a, the other end 17b) in the axial direction opposed to the inner surface 15a facing the width direction of the dismantling space 13. , 15b, respectively.
One end 17a in the axial direction of the dismantling hanger 17 is supported by a hinge attached to the inner side surface 15a so as to be swingable in the depth direction (the direction of arrow D in the drawing). The other end 17b in the axial direction of the dismantling hanger 17 is detachably locked to a locking member attached to the inner side surface 15b. The dismantling hanger 17 is related to a withdrawal posture (indicated by a broken line) in which the other end 17b is drawn out of the dismantling space 13 from the opening 21 and a locking member provided on the inner side surface 15b at the other end 17b. It swings in the depth direction (the direction of arrow D in the figure) between the locked posture (indicated by the solid line). If the dismantling hanger 17 is displaced to 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. If the dismantling hanger 17 is displaced to the locked position, the entire duvet is located in the dismantling space 13, so that the feathers taken out by the dismantling operation can be prevented from scattering outside through the opening 21.

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

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

The processing bag B is a mesh-like material having a large number of holes that allow passage of dust finer than feathers mixed in feathers and dirt attached to feathers while prohibiting passage of feathers and small feathers. (Or a porous material). Dust includes dust, dust, mite droppings and dead bodies, feather debris (down fiber and powder), and the like. The processing bag B functions as a filter for separating unnecessary dust from feathers. The processing bag B is manufactured using a woven fabric having a density such that feathers and small feathers mixed in feathers do not go outside. The processing bag B has a predetermined air permeability such that the feathers can be washed and dried while the feathers are stored inside.
A dust removal pipe 35 that conveys the dust that has passed through the processing bag B to the disassembly dust collection chamber 41 is connected to an appropriate place (the lower part of the side surface in this example) of the collection chamber 31.
The door 33 that opens and closes the collection chamber 31 has a pressure enough to maintain the interior of the collection chamber 31 in a negative pressure state (a pressure lower than the atmospheric pressure) when the air in the collection chamber 31 is sucked from the dust removal pipe 35. What is necessary is just to have airtightness. In other words, the door 33 only needs to have such a tightness that an air flow capable of transporting feathers into the processing bag B can be created in the collection pipe 25.

The disassembly dust collection chamber 41 has a box shape having a hollow portion in which a dust collection bag (dust removing means in the disassembly / transfer process) 45 can be accommodated, and a door 43 that opens and closes the hollow portion on one side surface (for example, the front surface). It has.
The dust removing pipe 35 communicates with the inside of the dismantling dust collecting chamber 41 at the downstream end. The downstream end of the dust removal pipe 35 is exposed inside the disassembly dust collection chamber 41, and a dust collection bag 45 is detachably attached to the downstream end of the dust removal pipe 35 using a fastening band or the like. The dust collecting bag 45 is attached to the dust removing pipe 35 so that no gap is generated so that all dust can be collected without leakage. In this example, since the downstream end of the dust removal 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 the passage of air while prohibiting the passage of dust. The dust bag 45 functions as a filter for removing dust in the air sucked from the collection chamber 31. As the dust bag 45, a woven fabric having a predetermined density can be used. Since the dust collection bag 45 captures dust passing through the processing bag B and creates clean air, the holes provided in the dust collection bag 45 are smaller than the holes provided in the processing bag B. In other words, the dust bag 45 has finer meshes than the processing bag B. The clean air that has passed through the dust collection bag 45 is discharged to the outside (in the atmosphere) from an exhaust port (exhaust pipe 47) provided at an appropriate position in the disassembly dust collection chamber 41.
A blower (suction blower) 37 that sucks air from the collection chamber 31 and introduces the air into the disassembly dust collection chamber 41 is provided at an appropriate position in the middle of the dust removal pipe 35. In this example, the feathers are transferred from the recovery port 23 of the dismantling chamber 11 to the processing bag B via the recovery pipe 25 using the suction force generated by the blower 37, and passed 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 equal to (equivalent to) the amount of air introduced from the dust removal pipe 35 per unit time. It is desirable. In such a case, the disassembly dust collecting chamber 41 does not require a special sealing property. It is desirable that at least the inner diameter of the exhaust pipe 47 be set so that the inside of the disassembly dust collecting chamber 41 has an exhaust capacity that does not make the environment higher than the atmospheric pressure.
When the collection of all the feathers removed from the duvet is completed, the worker removes the processing bag B from the collection pipe 25, closes the opening of the processing bag B, and moves the processing bag B to the washing machine 50.

<Washing machine>
The washing machine 50 removes various stains attached to the feather, and dewaters the washed feather. Washing of feathers is performed for each processing bag B (in a state of being stored in the processing bag B). In this example, in order to avoid damage to the feathers, the feathers are washed using only water or lukewarm water in principle. However, when it is determined that the dirt and smell attached to the feather cannot be removed only with water or lukewarm water, the feather is washed using a cleaning solution obtained by adding a 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 drying section 60 while being stored in the processing bag B.

<Drying section>
The drying unit 60 includes a pre-drying chamber (primary drying means) 61 for semi-drying feathers, main dryers (secondary drying means) 69 and 69 for completely drying 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 collection chamber (dust removing means in a drying process) 73 for removing dust contained in the recovered waste heat And a waste heat supply pipe (waste heat induction pipe) 79 for supplying 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 processing 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 that allows a worker to enter the inside of the pre-drying chamber 61 and work. The worker enters and exits the pre-drying chamber 61 from the door 63.

The drying hanger 65 is a means for suspending the processing bag B in a substantially folded state, and is made of, for example, a long bar. The drying hanger 65 is configured such that the lower ends of the processing bags B are separated from each other when the processing bags B are suspended in a two-weave posture (for example, an inverted V-shaped posture or an inverted U-shaped posture). It is desirable to have a configuration in which the processing bag B can be hung. For example, one drying hanger 65 can include two or more long bars 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 suspended from the drying hanger 65. The chamber 61 may have a configuration in which two or more processing bags B can be suspended simultaneously in the pre-drying chamber 61 at one time. For example, one drying hanger 65 has a configuration in which a plurality of processing bags B can be hung from the drying hanger 65, that is, a configuration in which the processing bags B can be hung at different positions in the longitudinal direction. You may. Alternatively, the pre-drying chamber 61 may include two or more (two or more sets) of drying hangers 65, and may have a configuration in which a plurality of processing bags B can be hung on each of the drying hangers 65.

  A blower fan 66 that blows the air in the pre-drying chamber 61 toward the processing bag B may be provided in the pre-drying chamber 61. For example, the blower fan 66 is located at a position where air can be blown between opposed lower end portions (between opposed side surfaces) of one processing bag B suspended in a two-folded posture, as a floor of the pre-drying chamber 61. It can be placed on a surface or in a suitable location below the pre-drying chamber. By installing a blower fan 66 in the pre-drying chamber 61, the flow of air is promoted in a portion of the surface of the processing bag B where air tends to stay, and the air with a flow spreads over the entire surface of the processing bag B. Becomes possible. By doing so, the drying time of the feathers stored in the processing bag B can be shortened as a whole. In particular, 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 installation of the blower fan 66 is set. Is very effective. Optionally, a guide means such as a pipe for guiding air to an arbitrary position and direction may be provided so that air having a flow generated by the blowing fan 66 can be blown to an arbitrary position of the processing bag B. Further, the blower fan 66 may be a means for simply stirring 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 (the 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 radiating port (radiating pipe 67) for releasing waste heat used for pre-drying to the outside (in the atmosphere) at another appropriate place (the ceiling in this example).
Here, the inner diameter of the heat radiation pipe 67 is determined based on the air volume of the blowers provided in the main dryers 69 and 69 and the air volume of the blower 72. The inner diameter of the heat radiating pipe 67 is set so that the amount of air discharged per unit time from the heat radiating pipe 67 is equal to (equivalent to) the amount of air introduced from the waste heat supply pipe 79 per unit time. It is desirable to be done. In this case, the pre-drying chamber 61 does not require a special airtightness. It is desirable that at least the inner diameter of the heat radiating pipe 67 is set so that the inside of the pre-drying chamber 61 has an exhausting capacity that does not make the environment higher than the atmospheric pressure.

  The main dryer 69 is a known dryer provided with a heating unit that generates hot air by heating air. Generally, gas, electricity, or steam is used as the heat source. The main dryer 69 completely dry the feathers together with the processing bag B. The main drier 69 is a so-called drum type drier, in which hot air is spread over the entire feather while rotating the processing bag B to completely dry the feather. The main dryer 69 dries feathers with hot air of about 70 degrees. In this example, the waste heat from the main dryer 69 near 70 degrees is introduced into the pre-drying chamber 61 and reused. The high-temperature exhaust gas discharged from the main dryer 69 is first introduced into the dry dust collecting chamber 73 from the waste heat recovery pipe 71.

The dry dust collecting chamber 73 is a means for removing dust contained in the high-temperature exhaust gas discharged from the main dryer 69. Its structure is the same as that of the disassembly dust collecting chamber 41. That is, the dry dust collecting chamber 73 has a box shape having a hollow portion in which a dust collecting bag (dust removing means in a drying step) 77 can be accommodated, and a door 75 that opens and closes the hollow portion on one side surface (for example, the front surface). It has.
The waste heat recovery pipe 71 communicates with the inside of the dry dust collection chamber 73 at the downstream end. The downstream end of the waste heat recovery pipe 71 is exposed in the dry dust collection chamber 73, and the downstream end of the waste heat recovery pipe 71 is detachably attachable to a dust collection bag 77 using a tightening band or the like. Attached to. The dust collection bag 77 is attached to the waste heat recovery pipe 71 so that no gap is generated so that all 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 waste heat recovery pipes 71a, 71a are connected at their upstream ends to the main dryers 69, 69, respectively, and the waste heat recovery pipe 71b is connected to the waste heat recovery pipes 71a, 71a on the upstream side and is dried and collected at the downstream end. It communicates with the inside of the dust chamber 73. The high-temperature exhaust gas discharged from the main dryers 69 and 69 and flowing through the waste heat recovery pipes 71a and 71a joins 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 the passage of air while prohibiting the passage of dust. The dust collecting bag 77 functions as a filter for removing dust in waste heat introduced from the main dryers 69, 69. A woven fabric woven at a predetermined density can be used for the dust collecting bag 77. Since the dust collecting bag 77 catches the dust that has passed through the processing bag B during the main drying and creates clean air, the holes provided in the dust collecting bag 77 are smaller than the holes provided in the processing bag B. In other words, the dust collecting bag 77 has finer meshes 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 in this example) of the dry dust collecting chamber 73. Since clean waste heat after dust collection is introduced into the predrying chamber 61, it is possible to prevent dust from adhering to the surface of the processing bag B in the predrying step. A relatively high temperature (for example, about 65 degrees) drying air is introduced into the predrying chamber 61.
Here, the inner diameter of the waste heat supply pipe 79 is determined based on the air volume of the blower provided in the main dryers 69 and 69 and the air volume of the blower 72. The inner diameter of the waste heat supply pipe 79 is equal to (equivalent to) the amount of air discharged per unit time from the waste heat supply pipe 79 with respect to the amount of air introduced from the waste heat recovery pipe 71 per unit time. It is desirable to be set to be. In such a case, the dry dust collecting chamber 73 does not require a special airtightness. Note that it is desirable that at least the inner diameter of the waste heat supply pipe 79 be set so that the drying and dust collecting chamber 73 has an exhaust capacity that does not make the environment higher than the atmospheric pressure.

  A blower 72 for sending out exhaust gas discharged from the main dryer 69 toward the downstream side may be additionally provided at an appropriate position in the intermediate 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 from the main dryers 69, 69 has joined. The blower 72 always forcibly introduces fresh exhaust gas into the pre-drying chamber 61 by creating an exhaust stream at a predetermined speed. The blower 72 may be provided at an appropriate location of the waste heat supply pipe 79, or may be provided at an appropriate location of the heat radiation pipe 67. In addition, the blower 72 can be installed in all of the waste heat recovery pipe 71, the waste heat supply pipe 79, and the heat radiation pipe 67, or alternatively, can be selectively provided for each pipe.

<Filling part>
The filling section 90 includes a weighing device 91 for measuring the weight of the down and a filling machine (filling means) 93 for filling the down into the side cloth C for the new duvet. In the filling section 90, the feather after drying is measured by the measuring device 91, new feathers in an amount corresponding to the shortage are added, and the filling machine 93 fills the new side cloth C with feathers.
The weight of the feather after the main drying is measured by the measuring device 91 for each processing bag B (in a state where the feather is contained in the processing bag B). Here, “measuring the feathers together with the processing bag B” means that the entire amount of the feathers is measured without removing the feathers from the processing bag B. If the feathers are weighed together with the processing bag B, the feathers do not adhere to the weighing container (or weighing dish) provided in the weighing device 91, so that mixing of feathers derived from different duvets can be prevented and cleaning of the weighing container can be prevented. It will be easier.

By weighing the feathers after the main drying, the amount of feathers that is insufficient with respect to the total amount of feathers to be filled in the new side cloth C is calculated. A new feather in an amount corresponding to the shortage is added to the feather after the main drying, and the total weight of the feather to be filled in the new side cloth C is adjusted.
The filling machine 93 uniformly mixes the feather after the main drying and the newly added feather, and blows the feather from the nozzle. The worker uses the filling machine 93 to fill each cell of the side cloth C with feathers.
Finally, the feather blowing port provided on the new side cloth C is sewn to complete the duvet regeneration process, that is, re-tailoring.

<Feather management>
In the feather product regeneration system 1, regeneration processes for a plurality of duvets are performed simultaneously in parallel. Therefore, in the feather product reproduction system 1, a plurality of processing bags B are used at the same time. Each processing bag B is assigned a unique reference number (identifier) that is identified from other processing bags B.
The identification number assigned to each processing bag is linked with information (name, telephone number, etc.) identifying the customer who has requested the duvet regeneration process and the details of the request from the customer (hereinafter referred to as “customer information”). Managed.
This management includes, for example, entering customer information and a serial number in an order receipt, and attaching an identification tag describing a serial number to each of the duvet, processing bag, and new side fabric C selected by the customer. And so on.
As described above, the serial number assigned to the processing bag and the customer information are linked and managed, and by performing each processing related to feather regeneration for each processing bag, mixing and mixing of feathers derived from feather products of different customers are mistaken. Can be prevented.

<Process flow>
Hereinafter, each process in the feather product reproduction system will be described with reference to flowcharts. FIG. 2 is a flowchart showing a flow of processing in the feather product reproduction system.

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

In step S4, the feathers are washed and dehydrated together with the processing bag B. That is, the worker removes the processing bag B with feathers from the collection chamber 31, closes the opening of the processing bag B, and moves the processing bag B to the washing machine 50. The operator turns on the switch of the washing machine 50 and performs washing and dehydration of the feathers by the washing machine 50.
In step S5, the feathers are pre-dried together with the processing bag B. That is, the operator takes out the processing bag B after the completion of dehydration from the washing machine 50 and moves it to the pre-drying chamber 61. The operator hangs 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 a part of the moisture is removed from the feathers before the main drying by using the waste heat. When the main dryer 69 is not operating, the pre-drying step of step S5 is omitted, and the process proceeds to the main drying step of step S6.
In step S6, the feathers are completely dried together with the processing bag B. That is, the operator takes out the processing bag B after the completion of 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. In the main drying step, the processing bag B is dried in the main dryer 69 with high-temperature hot air while rotating. Dust that has passed through the processing bag B in the main drying step is collected in the dust collection bag 77 via the waste heat recovery pipe 71. Since clean waste heat after dust collection is introduced into the predrying chamber 61, dust can be prevented from adhering to the surface of the processing bag B in the predrying step.
If the pre-drying step in step S5 is omitted, the main drying time is set longer than the main drying time set for the feathers that have undergone the pre-drying step in order to completely dry the feathers.

In step S7, the feathers are weighed by the weighing device 91 together with the processing bag B.
In step S8, new feathers are added to the processing bag B to adjust the total weight of the feathers so that the amount of feathers to be filled into the new side cloth C is obtained.
In step S9, the new side cloth C is filled with feathers. That is, the worker prepares a new side cloth C having the same reference number as the reference number given to the processing bag B, and uses the filling machine 93 to add a required amount of feather to each cell of the side cloth C. Is blown in sequentially. After the filling of the feather is completed, the worker stitches the feather blowing port provided on the side fabric C to complete the re-dressing of the duvet.

<Effect>
In this example, each step of regenerating the duvet, i.e., washing, dehydration, drying, and weighing are performed for each processing bag, so that the feather taken out from one duvet and the feather 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 processing bag and dried by the present dryer, a large-scale cleaning work is required to remove the feathers attached to the drying drum. Complete removal is difficult. This is the same in a washing machine.
As described above, in this example, since each step of regenerating the duvet is performed for each processing bag, mixing of the feathers taken out from different duvets is prevented, and maintenance cost of each device is reduced. Can be.

  Since the drying of the feather containing moisture takes time, there is a large difference between the time required for washing and dehydration and the time required for drying the feather. In particular, in the present embodiment in which the feather regeneration process is performed for each processing bag, the drying time tends to increase. For example, in order to continuously perform a plurality of duvet regeneration processes without stagnation of each operation, it is necessary to allocate a plurality of (for example, three) drying apparatuses to one washing machine. . However, if a drying apparatus having a heating source is used for all of the drying apparatuses, the cost for introducing the equipment increases, and a large amount of fuel is required, so that the fuel cost and the environmental load increase. In the present embodiment, since the waste heat at the time of the main drying is used for the pre-drying, the main drying time can be reduced, the fuel required for drying the feathers can be reduced, and the environmental load can be reduced.
