Description

  The present invention relates to a method and apparatus for separating feathers used as fillings such as bedding and batting of clothing and the like.

Feathers are used for bedding, clothes, etc. as fillings or batting, but feather products are usually divided into down, small feathers, large feathers, etc., and these are usually used in combination.
Feather has a slightly bent wing shaft from the front to the back, with soft wings on both sides and small wings on the left and right. Down is a feather without a wing shaft, a ball-shaped waterfowl feather in which two or more wings derived from a small original wing shaft and its tip are shaped like a dandelion cotton hair, and the trunk wing shaft is not clear Is. Because the down has spines (nodes) on the wings, the downball and the downball are difficult to stick together (referred to as mutual exclusion) and are extremely bulky.
On the other hand, since the feather has a curved wing shaft, it has a repulsive function like a leaf spring. Therefore, by mixing the feather in the down, it has a repulsive force when compressed as a stuffing or batting. In the case of a futon, it is used by mixing down and feathers as stuffed in a side sack. Feather futon is defined as a mixture of 50% or more of down, and feather futon is defined as a mixture of 50% or more of feather. Has been.
When used for a long period of time as bedding, cushions, etc., the feathers are damaged or broken, or the comrades of the down are entangled to form a ball down. However, if a large force is applied to the down ball, the down of the down ball Will pierce into the feathers of other downballs, and the spines and spines on the feathers will be caught, making it difficult to recover the bulk and reducing the bulkiness.
Repeatedly wearing a futon every day means that if you repeatedly apply pressure to the futon, the downball and the downball will stick together, or a mass of several downballs will be gathered together in a dumpling form, The ball will be heavier and less bulky. In addition, the down ball feathers are not robust and are thin and delicate. While pressure is repeatedly applied, the tip portion is damaged and dropped due to catching of spines and spines, friction between down balls and down balls, etc. A short fiber of about ~ 2 mm is produced. The fiber is almost not bulky. It must be separated and sorted for each type of feather, and dust must be removed. As such an apparatus, there is known an apparatus provided with a plurality of floating chambers for floating and separating feathers to be processed (see Patent Document 1).

The floating separation chamber has a tower-like body, has a fan at the lower part thereof, supplies feathers to be processed toward the fan, and raises the feathers in the tower body by the rotation of the fan. Ascends to the top of the tower, and heavy feathers accumulate at the bottom. A plurality of the towers are provided, and the feather selection is repeated a plurality of times for each tower.
The feathers separated and collected at the bottom of each tower are collected by a collection blower.
In this separation and collection apparatus, since a plurality of towers separate and sort feathers, the number of towers according to the number of collections to be separated is necessary, and one tower is once. Only the two types of feathers were selected by this operation, and it was not possible to select multiple types by one operation.
JP-A-62-137088

In view of the above points, the present invention collects new feathers or used feathers, agitates, and employs air feeding means, so that down, small feather, ball down, large feather can be used according to the type of feather. The purpose is to enable selective separation without damaging feathers by a single treatment for a plurality of species.
In the present invention, as described above, it is possible to separate and remove the wound feather fibers and other dust from the gathered feathers before sorting the feathers.

In the invention of the sorting method according to claim 1, a plurality of chambers that are in contact with the first chamber provided with the feather outlet and are partitioned by the partition so as to gradually have a distance from the first chamber are arranged at the upper part of the partition. Communicating with each other, the communication portion is a feather air passage, and the feather air passage between the first and second chambers is provided with a shutter, and the feather blown into the first chamber is stirred. In the method of separating and sorting the feathers into the respective chambers according to the difference in the free fall point of the feathers, the first chamber between the first chamber and the second chamber. In a state where the shutter provided on the partition wall is sealed, the feathers are stirred in the first chamber, then the shutter between the first and second chambers is opened, Feathers staying in the upper chamber was blown into the second chamber direction, and the feathers to each of the plurality of chambers below the second chamber so as to separate deposit.
According to the invention of the sorting method of claim 2, in the separation and sorting method of claim 1, the shutter provided between the first and second chambers for blocking the feather air passage is closed or opened as appropriate. Thus, the feathers were stirred in the first chamber or were blown from the first chamber to the second chamber.
In the invention of the separation / separation apparatus according to claim 3, in the separation / separation method according to claim 1, when the first chamber is sealed and the feathers are stirred and separated, damage is caused by the sieve provided at the lower part of the first chamber. The feather fiber dust was separated.
In the invention of the separation / separation apparatus according to claim 4, a plurality of chambers are arranged in contact with the first chamber having a feather outlet and partitioned by a partition so as to gradually have a distance from the first chamber, A shutter that allows the chambers adjacent to the upper part of the partition walls of the plurality of chambers to communicate with each other to provide a feather air passage, and that allows the air passage to be appropriately blocked and opened only at the partition wall between the first and second chambers. Provided at the bottom of each chamber is a discharge means for removing the processing feathers in each chamber out of the chamber.
According to the invention described in claim 5, in the invention described in claim 4, a sieve is provided in the lower part of the first chamber, and damaged feather fiber dust is sieved in the lower part of the first chamber.
In the invention described in claim 6, in the invention described in claim 4, an auxiliary air blowing port capable of blowing air toward the feather air passage is provided.

  The present invention is a single housing that is in contact with a first chamber provided with a feather outlet and is configured to communicate with a plurality of chambers that form a feather air passage in the upper part so that the distance from the first chamber gradually increases. Since the feathers blown out from the feather outlet in the first chamber are allowed to fall freely from the upper part to the adjacent chambers below the second chamber from the first chamber, the second time from the first chamber is just one second. Feathers can be separated and collected into multiple types by blowing into the chamber below the chamber, which is extremely efficient compared to separating and accumulating the same operation many times as in the conventional method, and processing. This reduces the chance of damaging feathers.

  Further, the feathers sealed in the first chamber are agitated by the air blown into the first chamber. Accordingly, since the fibers are blown out from the first chamber after being sufficiently defibrated, entanglement of feathers and other agglomeration can be prevented, and selection can be performed accurately.

  Next, the feather separation / selection apparatus 100 of the present invention will be described. In the illustrated example, the feather separation / separation apparatus 100 includes a casing 6 in which a plurality of chambers 1, 2, 3, 4 and 5 are arranged in parallel, and a partition wall 7 separating adjacent chambers is located above the bottom surface of the casing 6. However, it does not reach the ceiling, and a feather air passage 8 is formed between the top of the partition wall 7 and the ceiling.

The first chamber 1 has a feather outlet 9 that blows feathers to be processed into the first chamber 1. The feather outlet 9 blows off feathers as described above, and can blow only pressure air by switching a switching valve (not shown). If the feather outlet 9 is opened at the lower part of the first chamber 1, it is effective for stirring the feathers in the first chamber 1, and it is preferable that the blown airflow flows in the upward direction in the first chamber 1. . In addition, an auxiliary air blowing port 16 that ejects compressed air toward the feather air passage 8 is provided in the upper portion of the first chamber 1. A sieve 10 is provided at the lower part of the first chamber, and a dust collecting chamber 11 is provided at the lower part of the sieve 10. The dust collecting chamber 11 is provided with suction means 13 for sucking and discharging the accumulated feather fiber dust 12 and the like.
An openable / closable shutter 14 is provided in the feather channel 8 above the partition wall 7 located between the first chamber 1 and the second chamber 2. The upper part of the sieve 10 of the first chamber and the lower part of each of the chambers 2, 3, 4 and 5 below the second chamber are used as accumulation places for the separated feathers F, respectively, and appropriate discharge means 15 such as a suction pipe are provided. Yes.

Next, the method of the present invention will be described.
Not shown FIG appropriate amount of feathers to be treated discharged from the storage container to the first chamber 1 through the down air outlet 9. When a predetermined amount of feathers is accommodated in the first chamber 1, the emission of the feathers is stopped, only air is blown out from the air outlet 9, and the feathers are stirred in the chamber 1. At this time, the shutter 14 between the first and second chambers is closed, and the feather air passage 8 between the first and second chambers is closed. The feather blowing direction of the feather outlet 9 is directed upward, the feathers blown into the first chamber 1 are agitated and separated in the first chamber, and the light feathers stay in the upper part in the first chamber.
The feather fiber dust 12 and the like separated during stirring of the feathers falls in the first chamber 1, passes through the sieve 10, and is collected in the dust collecting chamber 11. This process removes feathers or dust that cannot be reused in the feathers, so that the remaining feathers are appropriately divided into groups.

Next, the feathers staying in the upper part of the first chamber are blown out through the feather channel 8 by opening the shutter 14. The feathers that have passed through the opened shutter 14 and flew in the feather channel 8 in the direction of the parallel chambers 2, 3, 4, and 5 are heavy or have a shape that is not easily affected by the air flow. Successively fall into the second chamber 2 and the third chamber 3 that are close to the first chamber 1, and the selected feathers are deposited on the bottom of each chamber. If the feathers are divided into five in the order close to the chamber 1, the result is “large ball down + large feather”, “ball down + small feather”, “down + small feather”, “down”, “good quality down”. The above grouping can be appropriately changed depending on the number of chambers. When the required amount is reached, the feathers are discharged from the discharge means 15 at the bottom of each chamber.
In addition, in order to allow the circulating air to pass through the feather air passage 8 smoothly, an air discharge means (not shown) is appropriately provided in the end chamber 5.

  The present invention can be used to regenerate new feathers or feathers after use, and the feathers can be efficiently divided into a plurality of airflows in a single treatment. It can also be applied to materials such as fine shredder dust that can be transported.
