According to such a suction device, lint may be discharged to the outside together with air.
The present invention has been made in view of the above-described problems, and an object thereof is to provide a false twisting machine and a lint recovery device that can appropriately separate lint from air and suppress the lint from being discharged to the outside.
(1) The false twist processing machine of the present invention is provided with a fiber scrap recovery device for recovering fiber scraps, characterized in that,
the lint recovery device includes:
a lint transfer pipe provided with a plurality of suction portions for sucking lint generated in the false twist processing machine, the lint sucked from the plurality of suction portions being transferred together with air in the lint transfer pipe;
a lint recovery unit configured to recover the lint transferred in the pipe of the lint transfer pipe;
a cyclone separator provided between the lint transfer pipe and the lint recovery unit, for separating the lint from the air transferred in the pipe of the lint transfer pipe, and for recovering the separated lint to the lint recovery unit; and
an air discharge unit connected to the cyclone separator for discharging air from which the lint is separated,
the lint transfer piping is provided in plurality,
the cyclone separator is provided with one for each of the plurality of lint transfer pipes.
The false twist machine described in (1) above is a fiber dust collecting device for collecting fiber dust generated in the false twist machine. The lint sucked from the suction portion is transferred in the lint transfer piping, and is collected in the lint collection portion through the cyclone connected to the lint transfer piping. In the cyclone separator, lint is separated from air transferred in a pipe of the lint transfer pipe. The separated lint is collected in the lint collection unit, and the air from which the lint is separated is discharged from the air discharge unit. By providing the cyclone between the lint transfer pipe and the lint recovery unit in this manner, the lint and the air can be separated appropriately, and the lint can be prevented from being discharged to the outside from the air discharge unit. The cyclone is provided one for each of the plurality of lint transfer pipes. That is, the lint transfer piping is connected to the cyclone one by one. Therefore, the lint transfer piping can be connected to the cyclone without being limited by other lint transfer piping. Therefore, the lint transfer pipe and the cyclone can be connected at a suitable position where lint and air are well separated. The "proper position" corresponds to, for example, a position of the lint transfer pipe below the end portion on the lower side of the air discharge portion.
(2) The false twist processing machine of the present invention is provided with a fiber scrap recovery device for recovering fiber scraps, characterized in that,
the lint recovery device includes:
a lint transfer pipe provided with a plurality of suction portions for sucking lint generated in the false twist processing machine, the lint sucked from the plurality of suction portions being transferred together with air in the lint transfer pipe;
a lint recovery unit configured to recover the lint transferred in the pipe of the lint transfer pipe;

The false twist machine described in the above (2) is a fiber dust collecting device for collecting fiber dust generated in the false twist machine. The lint sucked from the suction portion is transferred in the lint transfer piping, and is collected in the lint collection portion through the cyclone connected to the lint transfer piping. In the cyclone separator, lint is separated from air transferred in a pipe of the lint transfer pipe. The separated lint is collected in the lint collection unit, and the air from which the lint is separated is discharged from the air discharge unit. By providing the cyclone between the lint transfer pipe and the lint recovery unit in this manner, the lint and the air can be separated appropriately, and the lint can be prevented from being discharged to the outside from the air discharge unit. Further, since the lint recovery section has a smaller number than the plurality of lint transfer pipes, the overall structure of the lint recovery device can be made compact. Further, by providing the cyclone, the lint can be formed into a pellet and discharged, and therefore, the volume occupied by the lint in the lint recovery portion can be suppressed. By separating the lint from the air and discharging the air from the air discharge portion, the volume occupied by the air can be suppressed as compared with a system in which the air cannot be separated as in a conventional lint recovery apparatus in which a blower or the like is connected to the lint transfer pipe. As a result, in the lint recycling device of the present invention, a large amount of lint can be stored in the lint recycling portion, and the number of lint recycling portions can be suppressed, as compared with the conventional lint recycling device. In addition, if the number of lint recovery sections is small, the frequency of replacement or the like can be reduced, and the load on the operator can be reduced.
According to the lint recovery device described in the above (2), the lint can be separated from the air satisfactorily, and the lint can be further prevented from being discharged to the outside from the air discharge portion.

the air discharge unit is configured such that a flow rate of air discharged from the air discharge unit is greater than a flow rate of air discharged from the lint discharge unit.
According to the false twist machine described in the above (3), the lint can be separated from the air satisfactorily, and the lint can be further prevented from being discharged to the outside from the air discharge portion.
(4) The false twist texturing machine according to any one of the above (1) to (3), characterized in that,
the air discharge portion is provided so that a lower end of the air discharge portion is located above the lint transfer pipe.
According to the false twist texturing machine described in the above (4), it is possible to prevent the lint from being entangled in the air discharge portion and to prevent the lint from being satisfactorily separated from the air, and to satisfactorily separate the lint from the air.
(5) The false twist texturing machine according to any one of (1) to (4) above, wherein,
the air discharge portion is provided so as not to enter the inside of the cyclone separator, and the inside of the air discharge portion communicates with the inside of the cyclone separator.
According to the false twist texturing machine described in the above (5), the air discharge portion is provided so as not to enter the cyclone and to communicate with the cyclone, and therefore, the lint is not entangled in the air discharge portion, and the lint and the air can be separated satisfactorily.
The false twist machine described in (1) may be constituted by only the constitution described in (1), or the constitution described in (1) may be arbitrarily combined with any one of the constitutions described in (3) to (5) insofar as integration is possible. When the configuration described in (1) is combined with the configurations described in any one of (3) to (5), all or a part of the configuration described in (1) may be combined with all or a part of the configuration described in any one of (3) to (5) as long as integration is possible. Similarly, the false twist machine described in (2) may be constituted by only the constitution described in (2), or all or part of the constitution described in (2) may be combined with any of the constitutions described in any of (3) to (5) as long as integration is possible. When the configuration described in (2) is combined with the configurations described in any one of (3) to (5), all or a part of the configuration described in (2) may be combined with all or a part of the configurations described in (3) to (5) as long as integration is possible.
(6) The invention provides a fiber scrap recovery device, which is characterized by comprising:
a lint transfer pipe having a plurality of suction units for sucking lint, wherein the lint sucked from the suction units is transferred together with air in the lint transfer pipe;
a lint recovery unit configured to recover the lint transferred in the pipe of the lint transfer pipe;
a cyclone separator provided between the lint transfer pipe and the lint recovery unit, for separating the lint from the air transferred in the pipe of the lint transfer pipe, and for recovering the separated lint to the lint recovery unit; and
an air discharge unit connected to the cyclone separator for discharging air from which the lint is separated,
the above-mentioned fiber chips are polyester fibers or polyamide fibers,
the cyclone separator has:
a cylindrical main body portion connected to the lint transfer piping so that a longitudinal direction of the lint transfer piping extends along an inner peripheral wall, and configured to move the lint transferred in a pipe of the lint transfer piping downward along the inner peripheral wall by centrifugal force;
A lint transfer part connected to the lower part of the main body part; and
a lint discharging part for discharging lint separated from the air to the lint recycling part,
the lint transfer portion is configured to have an inclined portion having a diameter that decreases from a connection portion with the main body portion toward the lint discharge portion,
the inclined portion is formed in a tapered shape having an angle of 7 DEG or more and 10 DEG or less with respect to the vertical direction.
According to the lint recycling apparatus described in the above (6), lint sucked from the suction portion is transferred in the lint transfer piping, and is recycled to the lint recycling portion through the cyclone connected to the lint transfer piping. In the cyclone, the lint is separated from the air transferred in the pipe of the lint transfer pipe by moving the lint downward along the cylindrical inner peripheral wall by centrifugal force. The separated lint is formed into a lump and discharged from the lint discharge unit, and the discharged lint is recovered in the lint recovery unit, so that the lint can be suppressed from being discharged to the outside from the air discharge unit. Here, the density of the polyester fiber was 1.4g/cm 3 The density of the polyamide fiber was 1.12g/cm 3 However, it is difficult to separate lint from air for fibers such as polyester fibers and polyamide fibers, which have a relatively low density even among the fibers. Therefore, by providing the cyclone between the lint transfer pipe and the lint recovery portion, even when the density of lint is relatively small, the lint and air can be appropriately separated,the lint can be suppressed from being discharged to the outside from the air discharge portion. In particular, by forming the inclined portion in a tapered shape having an angle of 7 ° or more and 10 ° or less with respect to the vertical direction, it is possible to separate the lint and the air with high accuracy, and to prevent the lint discharge portion from being clogged with the lint and to discharge the lint from the lint discharge portion satisfactorily.

an air discharge unit connected to the cyclone separator for discharging air from which the lint is separated,
the air discharge unit is configured such that a flow rate of air discharged from the air discharge unit is greater than a flow rate of air discharged from the cyclone separator to the lint recovery unit.
According to the lint recycling apparatus described in the above (8), lint sucked from the suction portion is transferred in the lint transfer piping, and is recycled to the lint recycling portion through the cyclone connected to the lint transfer piping. In the cyclone separator, fibers are separated as lint from air transferred in a pipe of the lint transfer pipe. The separated lint is collected in the lint collection unit, and the air from which the lint is separated is discharged from the air discharge unit. By providing the cyclone between the lint transfer pipe and the lint recovery unit in this manner, the lint and the air can be separated appropriately, and the lint can be prevented from being discharged to the outside from the air discharge unit. In particular, the air discharge portion is configured such that the flow rate of air discharged from the air discharge portion is greater than the flow rate of air discharged from the cyclone separator to the lint recovery portion. Therefore, the lint can be separated from the air satisfactorily, and the lint can be further suppressed from being discharged to the outside from the air discharge portion.
(9) The lint recycling apparatus according to any one of (6) to (8) above, characterized in that,
the air discharge portion is provided so that a lower end of the air discharge portion is located above the lint transfer pipe.

[ false twisting machine ]
The false twisting machine 101 is configured as a textile machine for producing a processing yarn rich in stretchability by applying false twisting to thermoplastic synthetic fibers such as polyester and polyamide, for example. Referring to fig. 1, in a false twisting machine 101, a main body 102 is arranged to extend in the vertical direction. Further, the false twist texturing machine 101 includes: a yarn feeding creel 104 disposed to face the main body 102 with the working space 103 therebetween, and holding a plurality of yarn feeding packages 105; a false twisting device 106 disposed above the main body 102 for false twisting the fiber Y as a yarn supplied from the yarn supply bobbin cradle 104; and a winding device 107 provided in the main body 102 for winding the fiber Y false-twisted by the false twisting device 106; etc. The winding device 107 is provided with 4 layers in the up-down direction. Further, the winding device 107 is provided in plural in the front-rear direction in each of the 1 st to 4 th layers. The front-rear direction in which the plurality of winding devices 107 are arranged in each of the 4 layers arranged in the up-down direction is a direction along the horizontal direction, and is a direction perpendicular to the direction in which the yarn feeding creel 104 is arranged with the main body 102 (the left-right direction).
In the yarn path from the yarn feeding bobbin cradle 104 to the false twisting device 106, a 1 st yarn feeding roller 108, a yarn moving guide 109, a 1 st heating device 110, and a cooling device 111 are arranged in this order from the upstream side in the yarn advancing direction. Further, a 2 nd yarn feeding roller 112, an interlacing nozzle 113, a 2 nd heating device 114, a 3 rd yarn feeding roller 115, and an oil feeding roller 116 are disposed in this order from the upstream side in the yarn advancing direction on the yarn path from the false twisting device 106 to the winding device 107.
The 1 st godet 108 is disposed above the working space 103. The 1 st heating device 110 is disposed above the work space 103 and above the 1 st godet 108. The cooling device 111 is disposed on the main body 102 side of the 1 st heating device 110 above the working space 103. The 1 st heating device 110 and the cooling device 111 are disposed above the working space 103 so as to extend obliquely upward away from the main body 102. The yarn moving guide 109 is disposed between the 1 st yarn feeding roller 108 and the 1 st heating device 110 in the up-down direction, and is configured to pass the fiber Y through the 1 st heating device 110 and the cooling device 111 when the yarn is hooked on the false twisting machine 101.
The 2 nd godet 112 is disposed above the main body 102. The interlacing jet 113 is disposed above the main body 102 and below the 2 nd godet 112. The 2 nd heating device 114 is provided in the main body 102, is disposed on the back side of the winding device 107 as viewed from the working space 103, and extends in the vertical direction from the 1 st layer to the 4 th layer of the 4-layer winding device 107. The devices are arranged such that the yarn path from the yarn supply creel 104 to the winding device 107 is formed to enclose the working space 103.
In the false twisting machine 101, the fiber Y as a yarn fed from the yarn feeding bobbin cradle 104 is fed to the above-described devices and wound up on the winding device 107, thereby forming a package 117. First, the 1 st to 3 rd godet (108, 112, 115) is a roller for transporting the fiber Y from the upstream side to the downstream side in the yarn traveling direction, and each yarn transporting speed is set so that the yarn transporting speed of the 2 nd godet 112 is faster than the yarn transporting speed of the 1 st godet 108. Thus, fiber Y is drawn between the 1 st and 2 nd godets 108 and 112. Further, each yarn conveying speed is set so that the yarn conveying speed of the 3 rd godet 115 is slower than the yarn conveying speed of the 2 nd godet 112. Thus, the fiber Y is relaxed between the 2 nd and 3 rd godets 112 and 115.
The fiber Y stretched between the 1 st godet 108 and the 2 nd godet 112 is then twisted and fed by, for example, a false twisting device 106, which is a friction disk type two-for-one twister. The twist formed by the false twisting device 106 propagates to the 1 st godet 108, and the fiber Y which is drawn and twisted while being heated by the 1 st heating device 110 is cooled by the cooling device 111, and the twist is fixed. The twisted and heat-set fiber Y is untwisted to the 2 nd godet 112 after passing through the false twisting device 106.
The fiber Y thus drawn and false twisted is appropriately formed into a entangled portion in the interlacing jet 113, and after the coagulation is imparted, the fiber Y is subjected to a relaxation heat treatment in a 2 nd heating device 114, and is wound on a paper tube by a winding device 107 via an oil feeding roller 116, thereby forming a package 117. Then, the package 117 in the full-wound state is removed from the winding device 107 by the operator. Then, the operator installs a new paper tube in the winding device 107, and resumes the winding operation on the paper tube. In this way, the package 117 is replaced. The lint recycling apparatus 1 of the present embodiment is provided in the false twist machine 101. The following describes the lint recovery device 1 according to the present embodiment.
[ outline of fiber chip recovery device ]
Referring to fig. 2, the lint recycling apparatus 1 includes, for example, a plurality of lint transfer pipes 11 (11 a to 11 d), one lint return container 13 provided for the plurality of lint transfer pipes 11 (11 a to 11 d), and a plurality of cyclones 30 provided for each of the plurality of lint transfer pipes 11 (11 a to 11 d). The plurality of cyclone separators 30 are disposed between the lint transfer piping 11 (11 a to 11 d) and the lint recovery container 13. The cyclone 30 separates lint from air transferred in the pipe of the lint transfer pipe 11, and recovers the separated lint into a lint recovery container, which will be described in detail later. The "lint" includes yarn flying, and includes, in addition to lint having a relatively short length, lint in which lint having a relatively short length is gathered, yarn lint having a relatively long length, and the like. The "lint recovery container 13" corresponds to the "lint recovery unit" of the present invention.
The lint recycling apparatus 1 is provided in the false twist processing machine 101. The plurality of lint transfer pipes 11 of the lint recycling device 1 are arranged in correspondence with each layer of the winding device 107 in which, for example, 4 layers are arranged in the vertical direction in the false twisting machine 101. Therefore, the lint recovery device 1 of the present embodiment, in which the 4-layer winding device 107 is disposed, includes 4 lint transfer pipes 11 (11 a to 11 d). The lint transfer pipes 11 (11 a to 11 d) are arranged to extend in the front-rear direction. In each of the winding devices 107 from the 1 st to 4 th layers, the winding devices 107 are arranged in a line in the front-rear direction, and the lint transfer pipes 11 (11 a to 11 d) extend in the front-rear direction in which the winding devices 107 are arranged. The lint transfer pipes 11 (11 a to 11 d) suck the fibers Y (see fig. 1) from the vicinity of the winding devices 107 arranged in the front-rear direction in the layers of the winding devices 107 arranged in 4 layers up and down, and transfer the fibers Y together with air. The 4 lint transfer pipes 11 (11 a to 11 d) are connected to a common lint recovery container 13. Then, the air containing the fibers Y transferred in the pipes of the lint transfer pipes 11 (11 a to 11 d) is separated into the lint as the fibers Y and the clean air from which the lint is separated in the cyclone 30. The lint separated from the air is recovered by the lint recovery container 13. The clean air from which the lint is separated is discharged to the outside from an air discharge unit 50 (see fig. 4 described later).
However, by providing the cyclone 30 and discharging the air from which the lint is separated to the outside from the air discharge portion 50 (see fig. 4 described later), the number of lint recovery containers 13 can be reduced to a smaller number than the number of lint transfer pipes 11 (11 a to 11 d), and the entire lint recovery device 1 can be made compact. That is, by providing the cyclone, the lint can be formed into a pellet and discharged, and therefore, the volume occupied by the lint in the inside of the lint recovery container 13 can be suppressed. Further, by separating the lint from the air and discharging the air from which the lint has been separated from the air discharge unit 50, the volume occupied by the air can be suppressed as compared with a system in which the air cannot be separated as in a conventional lint recovery apparatus in which a blower or the like is connected to the lint transfer piping 11 (11 a to 11 d). As a result, in the lint recycling device 1 of the present embodiment, a large amount of lint can be stored in the lint recycling container 13, and the number of lint returns to the storage 13 can be suppressed, as compared with the conventional lint recycling device. Further, if the number of lint recovery containers 13 is small, the frequency of replacement or the like can be reduced, and the load on the operator can be reduced. In the present embodiment, one lint recovery container 13 is provided for all of the plurality of lint transfer pipes 11 (11 a to 11 d), but the present invention is not limited thereto, and the number of lint recovery containers 13 may be smaller than the number of lint transfer pipes 11 (11 a to 11 d).
The yarn collecting apparatus 1 collects such yarn as yarn without cutting the yarn when the yarn is switched by the winding device 107 of the false twist machine 101. That is, as shown in fig. 1, the lint recovery device 1 is configured to recover, as lint, the fiber Y continuously supplied from the yarn feeding bobbin cradle 104 to the vicinity of the winding device 107 via the respective devices (110, 111, 106, 114) or the like, from the suction portion when the fiber Y is hooked on the false twist machine 101 or when the package 117 formed by the winding device 107 of the false twist machine 101 is replaced. In this way, when the package 117 is replaced in the winding device 107 of the false twist machine 101, the fiber Y continuously supplied to the vicinity of the winding device 107 can be recovered, and therefore, the operation of the false twist machine 101 can be continued without cutting the yarn. The details of the structure of the lint recovery device 1 will be described in more detail below.
[ lint transfer piping ]
Referring to fig. 2, the lint transfer piping 11 (11 a to 11 d) is configured as piping for transferring the fibers Y sucked from the plurality of suction portions 15, in which the plurality of suction portions 15 for sucking the fibers Y (refer to fig. 1) are provided in the vicinity of each winding device 107. The suction portion 15 for sucking the fiber Y will be described later. The lint transfer pipe 11 is provided in a hollow circular tube shape, for example. The lint transfer piping 11 (11 a to 11 d) is provided in plurality, and in the present embodiment, 4 lint transfer piping are provided as described above.
As the 4 lint transfer pipes 11 (11 a to 11 d), a 1 st lint transfer pipe 11a corresponding to the winding device 107 of the 1 st layer of the lowermost layer, a 2 nd lint transfer pipe 11b corresponding to the winding device 107 of the 2 nd layer from the bottom, a 3 rd lint transfer pipe 11c corresponding to the winding device 107 of the 3 rd layer from the bottom, and a 4 th lint transfer pipe 11d corresponding to the winding device 107 of the 4 th layer of the uppermost layer are provided. The lint transfer pipes 11 (11 a to 11 d) are disposed in the false twist machine 101 in a state where their longitudinal directions extend in the front-rear direction. Further, the 1 st to 4 th lint transfer pipes (11 a to 11 d) are arranged so as to extend in the front-rear direction at positions corresponding to the respective layers of the winding device 107 from the 1 st layer to the 4 th layer. In the present embodiment, the cyclone separator 30 is provided with a 1 st cyclone separator 30a provided between the 1 st lint transfer piping 11a and the lint recovery container 13, a 2 nd cyclone separator 30b provided between the 2 nd lint transfer piping 11b and the lint recovery container 13, a 3 rd cyclone separator 30c provided between the 3 rd lint transfer piping 11c and the lint recovery container 13, and a 4 th cyclone separator 30d provided between the 4 th lint transfer piping 11d and the lint recovery container 13.
One end (rear end shown in fig. 2) of each lint transfer pipe 11 (11 a to 11 d) in the longitudinal direction extending in the front-rear direction is closed, and the other end (front end shown in fig. 2) is connected to the cyclone 30.
[ suction portion ]
Referring to fig. 2, the suction portion 15 is provided as a mechanism for sucking the fibers Y (see fig. 1), and a plurality of the lint transfer pipes 11 (11 a to 11 d) are provided. The plurality of suction portions 15 provided in each lint transfer pipe 11 are configured to include a suction pipe 16 and an opening and closing mechanism 17 (see fig. 3 described later), and are arranged in the lint transfer pipes 11 (11 a to 11 d) along the longitudinal direction thereof. The plurality of suction portions 15 provided in the arrangement of the lint transfer pipes 11 (11 a to 11 d) are provided at positions corresponding to the winding device 107 in the lint transfer pipes 11 (11 a to 11 d). More specifically, the plurality of suction portions 15 are provided in the respective lint transfer pipes 11 (11 a to 11 d) at respective layers of the winding device 107 (see fig. 1) arranged vertically, for example, in 4 layers in the false twist processing machine 101 (see fig. 1), at positions corresponding to the winding devices 107 arranged in the front-rear direction.
The suction portions 15 provided in the 1 st to 4 th lint transfer pipes 11 (11 a to 11 d) are configured in the same manner. The same applies to the configuration in which a plurality of suction portions 15 are arranged in the lint transfer pipes 11 (11 a to 11 d).
The suction pipe 16 is a tubular member for sucking the fiber Y (see fig. 1), has a smaller diameter than the lint transfer pipes 11 (11 a to 11 d), and is provided to be bent and extended in the middle. One end side of the suction pipe 16 communicates with the lint transfer pipes 11 (11 a to 11 d), and a suction port (not shown) that is disposed in the vicinity of the winding device 107 (see fig. 1) and sucks the fibers Y is provided at the other end side. The fibers Y sucked from the suction port flow into the pipe of the lint transfer pipe 11.
Fig. 3 is a cross-sectional view showing an example of the suction portion 15 provided in the lint transfer pipe 11. Fig. 3 shows a state in which the opening/closing member 19 is pushed upward to open the suction port 16 a. Referring to fig. 3, the suction pipe 16 is connected in an inclined state with respect to the lint transfer piping 11 (11 a to 11 d). The suction pipe 16 is connected to the lint transfer pipes 11 (11 a to 11 d) at an acute angle to a direction from an upstream side (a rear side shown in fig. 3) toward a downstream side (a front side shown in fig. 3) of an air flow flowing in the pipe of the lint transfer pipe 11. That is, the suction pipe 16 is connected to the lint transfer pipes 11 (11 a to 11 d) at an acute angle with respect to a direction from one end side (rear side shown in fig. 3) toward the other end side (front side shown in fig. 3) connected to the lint recovery container 13. Accordingly, when the fiber Y (see fig. 1) sucked from the suction port (not shown) flows into the pipe of the lint transfer pipe 11, the fiber Y flows in a direction from the upstream side toward the downstream side of the air flow in the pipe of the lint transfer pipe 11. The fibers Y flowing into the tubes of the lint transfer piping 11 are transferred downstream by the air flow flowing in the tubes of the lint transfer piping 11.
The suction pipe 16 is provided with a compressed air injection nozzle hole 16d and a guide passage 16e. The compressed air injection nozzle hole 16d is provided as a nozzle hole for injecting compressed air into the suction pipe 16 between one end side provided with the outlet opening 16b and the other end side provided with the suction port 16 a. The compressed air injection nozzle hole 16d is configured to inject compressed air toward the outlet opening 16b, i.e., toward one end side, in the suction pipe 16. In the present embodiment, two compressed air injection nozzle holes 16d are provided. Both of the compressed air injection nozzle holes 16d extend from the suction port 16a side toward the outlet opening 16b side and extend from the outer peripheral side toward the inner peripheral side of the suction pipe 16, thereby communicating with the suction flow path 16 c. According to this configuration, both the compressed air injection nozzle holes 16d are configured to inject compressed air toward the outlet opening 16b side in the suction pipe 16. The number of the compressed air injection nozzle holes 16d is not limited to two.
The guide passage 16e of the suction pipe 16 is provided in the suction pipe 16 as a flow path of compressed air extending annularly along the circumferential direction of the suction pipe 16. The guide passage 16e communicates with a compressed air injection nozzle hole 16d and with a cylinder chamber 20 described later. The compressed air supplied to the cylinder chamber 20 flows into the guide passage 16e, flows into the compressed air injection nozzle hole 16d from the guide passage 16e, and is injected into the intake passage 16 c.
The cylinder chamber 20 is formed as a cylindrical space inside the main body 18, and is configured to be supplied with compressed air. The cylinder chamber 20 communicates with the guide passage 16e of the suction pipe 16 via a communication passage 20a provided in the main body 18. Accordingly, the compressed air supplied to the cylinder chamber 20 flows into the guide passage 16e and then into the compressed air injection nozzle hole 16d. Further, a compressed air supply pipe 23 for supplying compressed air to be injected from the compressed air injection nozzle hole 16d of the intake pipe 16 is connected and communicated to the cylinder chamber 20. The compressed air supply pipe 23 is connected to a compressed air supply source (not shown) that supplies compressed air. The compressed air supply pipe 23 is provided with a solenoid valve 24, and the solenoid valve 24 is opened and closed to switch between a communication state and a shut-off state, thereby controlling the supply of compressed air to the cylinder chamber 20. When the solenoid valve 24 is opened, the compressed air supply pipe 23 is in a communication state, and compressed air is supplied from the compressed air supply pipe 23 to the cylinder chamber 20. When the solenoid valve 24 is closed, the compressed air supply pipe 23 is in a shut-off state, and the supply of compressed air from the compressed air supply pipe 23 to the cylinder chamber 20 is shut off.
In the suction portion 15, the opening/closing member 19 is rotated about the rotation shaft 29 by the urging force of the spring member 22 disposed in the spring chamber 25 in a state in which the compressed air supply pipe 23 is shut off in a state in which the electromagnetic valve 24 is closed and the compressed air is not supplied to the cylinder chamber 20, and the suction port 16a is closed. In this state, the suction unit 15 does not perform the suction operation for the fiber Y (see fig. 1). On the other hand, when the compressed air supply pipe 23 is connected to supply compressed air to the cylinder chamber 20 with the solenoid valve 24 opened, the piston 21 is displaced upward to push up the opening/closing member 19 upward, and the suction port 16a is opened. Further, in a state where compressed air is supplied to the cylinder chamber 20, the compressed air flows into the compressed air injection nozzle hole 16d, and the compressed air is injected from the compressed air injection nozzle hole 16d into the suction flow path 16c of the suction pipe 16. The compressed air injected into the suction flow path 16c is injected toward the outlet opening 16 b. In this way, the compressed air injected into the suction pipe 16 from the compressed air injection nozzle hole 16d generates an air flow for transporting the fibers Y to the lint transfer pipe 11 side in the suction pipe 16, and further generates an air flow for transporting the fibers Y to the cyclone 30 side (front side shown in fig. 3) in the lint transfer pipe 11. In this way, the fibers Y sucked from the suction port 16a can be transferred in the pipe of the lint transfer pipe 11.
Further, if the fiber Y can be sucked from the suction port (see fig. 1) and the sucked fiber Y can be transferred in the pipe of the lint transfer piping 11 (11 a to 11 d), the mode is not limited to a specific mode. For example, compressed air may be injected into the suction pipe 16 as described above, or the inside of the lint transfer pipe 11 may be brought into negative pressure by suction by a blower, for example.
The flow rate of air in the pipes of the lint transfer pipes 11 (11 a to 11 d) is preferably 1000m/min or more. Therefore, when the flow rate of the air in the pipe of the lint transfer pipe 11 is less than 1000m/min, for example, a connection portion for supplying the compressed air may be provided at one end (for example, the rear end) of the lint transfer pipe 11 (11 a to 11 d), so that the compressed air supplied from the compressed air supply source (not shown) can be supplied from the one end of the lint transfer pipe 11 (11 a to 11 d) to the lint transfer pipe 11 (11 a to 11 d). Further, a conventionally provided blower may be provided near the cyclone separator 30 to suck the inside of the lint transfer piping 11 (11 a to 11 d) to make up for the shortage required to satisfy the flow rate of air of 1000m/min, for example.
[ cyclone separator ]
Fig. 4 is a perspective view showing an example of the cyclone 30 and the air discharge portion 50. Fig. 5 is a plan view showing an example of the cyclone 30 and the air discharge portion 50. Fig. 6 is an example of a front view of the cyclone separator 30. Fig. 4 to 6 also show the connection portion with the lint transfer pipe 11. In the present embodiment, the 1 st to 4 th cyclones 30a to 30d are provided as described above, but the 1 st to 4 th cyclones 30a to 30d have the same configuration.
Referring to fig. 4, the cyclone 30 includes a cylindrical main body 32, a tapered portion 42 provided below the main body 32, and a lint discharge portion 46 for discharging lint separated from air into the lint recovery container 13 (see fig. 2). The main body 32 includes a cylindrical portion 34 that forms a side wall, and an upper surface portion 36 that forms an upper end surface of the cylindrical portion 34. An opening 38 concentric with the cylindrical portion 34 and smaller in diameter than the cylindrical portion 34 is formed in the upper surface portion 36. The cyclone separator 30 does not completely separate the air from the lint, but the lint from which the air was separated also contains air. Therefore, not only the lint but also the air that is not separated together with the lint are discharged from the lint discharging portion 46.
The tapered portion 42 has an upper end portion having a circular shape with the same diameter as the cylindrical portion 34, and a lower end portion having a circular shape with a smaller diameter than the upper end portion. The tapered portion 42 is open at an upper end and a lower end, and has an inclined portion 44 that linearly tapers from the upper end toward the lower end in front view. The angle θ of the acute angle side between the vertical direction and the direction of the inclined portion 44 (hereinafter referred to as "taper angle θ") is preferably in the range of 7 ° to 10 ° (including upper and lower limit values), although the details of the inclined portion 44 will be described below. The tapered portion 42 is connected at an upper end portion to a lower end portion of the cylindrical portion 34. In addition, there is no member separating the respective interiors between the tapered portion 42 and the main body portion 32, and the interior of the tapered portion 42 communicates with the interior of the main body portion 32. The "tapered portion 42" corresponds to the "lint transfer portion" of the present invention.
The lint discharging portion 46 has a cylindrical shape with both ends open, and the inner diameter of the lint discharging portion 46 is equal to the inner diameter of the lower end portion of the tapered portion 42. The lint discharging portion 46 is connected to the lower end portion of the tapered portion 42 at the upper end portion so as to be concentric with the lower end portion of the tapered portion 42. The lint discharging portion 46 is connected to the lint collecting container 13 (see fig. 2) at a lower end portion. No member for partitioning the respective interiors is present between the lint discharging portion 46 and the tapered portion 42, and the interior of the lint discharging portion 46 communicates with the interior of the main body portion 32.
An air discharge unit 50 for discharging the air from which lint has been separated to the outside is provided above the cyclone 30. The air discharge portion 50 has a cylindrical pipe with both ends open, and the inner diameter of the air discharge portion 50 is the same as the diameter of the opening 38. The air discharge portion 50 is connected to the opening 38 at a lower end portion so as to be concentric with the opening 38. More specifically, the air discharge portion 50 is connected to the main body portion 32 such that the cylindrical portion of the air discharge portion 50 does not enter the interior of the main body portion 32 of the cyclone 30, and the lower end of the cylindrical portion of the air discharge portion 50 is coplanar with the lower surface of the upper surface portion 36 of the cyclone 30 (more specifically, the main body portion 32).
As shown in fig. 6, the air discharge portion 50 preferably has a lower end 50a of a cylindrical portion of the air discharge portion 50 located above the upper end 11U of the lint transfer pipe 11. This is because, according to the findings of the present inventors, when the lower end 50a of the cylindrical portion of the air discharge portion 50 is located below the upper end 11U of the lint transfer pipe 11, lint is entangled in the cylindrical portion of the air discharge portion 50, and good separation of the lint from the air is inhibited. Therefore, by making the lower end 50a of the cylindrical portion of the air discharge portion 50 at least above the upper end 11U of the lint transfer pipe 11, it is possible to prevent lint from being entangled in the cylindrical portion of the air discharge portion 50, and to separate the lint from the air satisfactorily. In the present embodiment, as shown in fig. 4, since the lower end of the cylindrical portion of the air discharge portion 50 is coplanar with the lower surface of the upper surface portion 36 (see fig. 4) of the main body portion 32, the lower end of the cylindrical portion of the air discharge portion 50 is located above the upper end of the lint transfer pipe 11, and therefore, lint can be separated from air satisfactorily.
However, when a plurality of lint transfer pipes 11 (11 a to 11 d) are connected to one cyclone 30, the connection position between the lint transfer pipes 11 (11 a to 11 d) and the cyclone 30 is limited. For example, the connection position between one lint transfer pipe 11a of the plurality of lint transfer pipes 11 (11 a to 11 d) and the cyclone 30 is restricted by the other lint transfer pipes 11b to 11 d. Then, the single lint transfer pipe 11a may not be connected to the cyclone 30 so as to be lower than the lower end of the cylindrical portion of the air discharge portion 50. Therefore, by connecting each of the plurality of lint transfer pipes 11 (11 a to 11 d) to the cyclone 30 one by one, the lint transfer pipes 11 (11 a to 11 d) can be connected to the cyclone 30 at a proper position where the lint is well separated from the air, that is, at a position below the lower end of the cylindrical portion of the lint transfer pipe 11 (11 a to 11 d) than the air discharge portion 50.
There is no member separating the respective interiors between the air discharge portion 50 and the cyclone 30 (more specifically, the main body portion 32), and the interior of the air discharge portion 50 communicates with the interior of the cyclone 30. Further, according to the findings of the inventors, when the inner diameter of the lint discharging portion 46 (i.e., the inner diameter of the lower end portion of the tapered portion 42) is larger than the inner diameter of the air discharging portion 50 (i.e., the diameter of the opening portion 38), the separation of the lint from the air becomes insufficient, and the lint may be discharged from the air discharging portion 50. Accordingly, the inner diameter of the lint discharging portion 46 (i.e., the inner diameter of the lower end portion of the tapered portion 42) is preferably smaller than the inner diameter of the air discharging portion 50 (i.e., the diameter of the opening portion 38).
In the present embodiment, the air discharge portion 50 and the lint discharge portion 46 are both cylindrical, but the present invention is not limited thereto, and may be square cylindrical. In this case, the opening area in the horizontal direction of the portion communicating with the inside of the main body portion 32 (i.e., the connection portion with the upper surface portion 36) is preferably larger than the opening area in the horizontal direction of the lint discharging portion 46.
As shown in fig. 5, the lint transfer pipe 11 is connected to the main body 32 at an upper portion of the main body 32 so as to extend along an inner peripheral wall 35 of the main body 32 of the cyclone 30 in the longitudinal direction. That is, the lint transfer pipe 11 is connected to the main body 32 so as to be a tangent line to the cylindrical portion 34 of the main body 32 of the cyclone 30 in a plan view. In other words, the lint transfer pipe 11 is connected to the main body 32 of the cyclone 30 so that the traveling direction of the air containing the fibers as lint transferred in the pipe of the lint transfer pipe 11 is along the inner peripheral wall 35 of the cylindrical portion 34. By connecting the lint transfer piping 11 and the cyclone 30 in this manner, the air containing lint transferred in the pipe of the lint transfer piping 11 moves in the circumferential direction along the inner peripheral wall 35 of the cylindrical portion 34 as shown in fig. 4. Accordingly, the lint contained in the air is transferred downward by centrifugal force, that is, centrifugal separation while rotating in the circumferential direction along the inner peripheral wall 35 of the cylindrical portion 34. The lint which moves downward while rotating along the inner peripheral wall 35 of the cylindrical portion 34 is further transferred along the inner wall 45 of the inclined portion 44 toward the lint discharge portion 46. The lint transferred to the lint discharging portion 46 is transferred from the lint discharging portion 46 to the lint collecting container 13 (see fig. 2). The lint is separated from the air containing lint transferred in the pipe of the lint transfer pipe 11, and the separated lint is recovered in the lint recovery container 13. On the other hand, the air from which the lint is separated is discharged to the outside from the air discharge portion 50.
In addition, when each of the plurality of lint transfer pipes 11 (11 a to 11 d) is connected to the cyclone 30 in one-to-one manner, the lint transfer pipes 11 (11 a to 11 d) can be connected to the cyclone 30 at appropriate positions, and the inner peripheral wall 35 of the cylindrical portion 34 can be secured, so that the lint can be reliably transferred to the tapered portion 42.
[ Effect of the invention ]
According to the lint recycling apparatus 1 of the present embodiment, the lint Y sucked from the suction unit 15 is transferred in the pipe of the lint transfer pipe 11, and is recycled as lint in the lint recycling container 13 through the cyclone 30 connected to the lint transfer pipe 11. In the cyclone 30, lint is separated from air transferred in the pipe of the lint transfer pipe 11. The separated lint is recovered in the lint recovery container 13, and the air from which the lint is separated is discharged from the air discharge portion 50. By providing the cyclone 30 between the lint transfer pipe 11 and the lint recovery container 13 in this manner, lint and air are appropriately separated, and the lint can be prevented from being discharged to the outside from the air discharge portion 50.
Further, according to the lint recovery device 1 of the present embodiment, the lint transfer pipe 11 is connected to the main body portion 32 so that the longitudinal direction of the lint transfer pipe 11 extends along the inner peripheral wall 35 of the cylindrical portion 34. Accordingly, the air moves in the circumferential direction along the inner circumferential wall 35 of the cylindrical portion 34, and the lint transferred in the pipe of the lint transfer pipe 11 moves downward along the inner circumferential wall 35 of the cylindrical portion 34 and the inner wall 45 of the inclined portion 44 by centrifugal force, that is, centrifugal separation, and is separated from the air. The lint separated from the air is recovered in the lint recovery container 13 via the lint discharge portion 46. The clean air from which the lint is separated is discharged from the air discharge portion 50. However, the air discharge portion 50 communicates the interior of the air discharge portion 50 with the interior of the main body portion 32 and is connected to the main body portion 32 so that the lower end of the air discharge portion 50 is coplanar with the upper surface portion 36 of the main body portion 32 without entering the interior of the main body portion 32. Therefore, the lint is not entangled with the air discharge portion 50, and the lint can be separated from the air satisfactorily.
Further, according to the lint recovery device 1 of the present embodiment, the tapered portion 42 has the inclined portion 44, and the diameter of the inclined portion 44 becomes smaller from the connection portion with the main body portion 32 toward the lint discharging portion 46. Since the lint can be separated from the air in the inclined portion 44, the lint can be further prevented from being discharged to the outside from the air discharge portion 50. The inclined portion 44 is formed in a tapered shape having an angle in the range of 7 ° to 10 ° (including upper and lower limit values) with respect to the vertical direction, whereby the lint can be separated from the air with high accuracy, and the lint discharge portion 46 is prevented from being clogged with the lint, so that the lint can be discharged from the lint discharge portion 46 satisfactorily. In particular, if the density of the lint is relatively high, it is relatively easy to separate the lint from air, but the false twisting machine 101 performs false twisting on thermoplastic synthetic fibers such as polyester and polyamide as described above, for example, to apply crimping. The density of the polyester fiber is 1.4g/cm 3 The density of the polyamide fiber was 1.12g/cm 3 Even in the fiber, the density is relatively small, and therefore, it is difficult to separate the polyester and polyamide from the air. In this regard, according to the lint recycling apparatus 1 described in the present embodiment, even if it is made of, for example, polyester, Even when the density of the lint such as polyamide is small, the lint can be separated from the air appropriately. Then, the separated lint is discharged from the lint discharge portion 46, and the discharged lint is recovered in the lint recovery device 1, so that the lint can be suppressed from being discharged to the outside from the air discharge portion.
Further, according to the lint recycling apparatus 1 of the present embodiment, the inner diameter of the lint discharging portion 46 (i.e., the inner diameter of the lower end portion of the tapered portion 42) is smaller than the inner diameter of the air discharging portion 50 (i.e., the diameter of the opening portion 38). Accordingly, the lint and the air can be appropriately separated, and the lint can be more effectively prevented from being discharged to the outside from the air discharge portion 50.
Experimental example
This embodiment is supported by the following experimental examples. The results of this experimental example are described. Fig. 7 is an example of a front view of the cyclone separator 30. Fig. 8 shows an example of experimental results showing the relationship between the taper angle θ and the flow rate of air in the air discharge portion 50 and the flow rate of air in the lint discharge portion 46. The fibers used in experimental examples 1, 2 and 3 described later were 75 denier false twisted yarns.
In fig. 7 and 8, the vertical direction is the Y direction, and in particular, the upward direction is the Y direction (positive direction) and the downward direction is the Y direction (negative direction). The flow rate shown in fig. 8 indicates the flow rate of the vector component in the Y direction, and indicates the air flow in the Y direction (positive direction) when the flow rate has a positive value, and indicates the air flow in the Y direction (negative direction) when the flow rate has a negative value.
Referring to fig. 7, the dimensions of the respective portions of the cyclone 30 are set to a Y-direction length a of the cyclone 30 as a whole, a Y-direction length b of the main body 32, an inner diameter c of the main body 32, a Y-direction length d of the air discharge portion 50, an inner diameter e of the air discharge portion 50, a Y-direction length f of the inclined portion 44, a Y-direction length g of the lint discharge portion 46, an inner diameter h of the lint discharge portion 46, and a taper angle θ. In experimental example 2 described later, the inner diameter of the inlet of the lint transfer pipe 11, which is the connection portion with the cyclone 30, is i.
Experimental example 1
In experimental example 1, the dimensions of each portion of the cyclone 30 were a=280 mm, b=80 mm, c (inner diameter) =80 mm, d=50 mm, e (inner diameter) =48 mm, g=10 mm, h (inner diameter) =31 mm, and the taper angle θ was changed to verify the suitability of the lint discharged from the lint discharge portion 46 (hereinafter referred to as "suitability of lint discharge"). The taper angle θ was verified at 10 °, 15 °, 30 °, 40 °. The Y-direction length f of the inclined portion 44 is determined according to the taper angle θ.
The results of the verification obtained in experimental example 1 are shown in table 1. Table 1 shows an example of experimental results showing the relationship between the taper angle θ and the suitability for discharging lint. In order to properly discharge the lint from the lint discharge portion 46, it is important to aggregate the lint into a pellet. The condition that the lint is in a lump and is satisfactorily discharged from the lint discharge portion 46 is judged as OK, the condition that the lint is not in a lump and is not discharged from the lint discharge portion 46 is judged as NG, and the condition that the lint is gathered into a lump and the lint discharge portion 46 is clogged with 1 out of 5 times is judged as Δ.
[ Table 1 ]
| Cone angle theta | 10° | 15° | 30° | 45° |
| Good fiber chip discharge performance | △ | NG | NG | NG |
As shown in table 1, if the taper angle θ exceeds 10 °, the suitability for the lint discharge is judged as NG. When the taper angle θ was 10 °, the fiber was found to be "Δ" by blocking the fiber discharge portion 46 1 time out of the 5 times, and found to be "OK" by collecting 4 times of the fiber into a lump and discharging the fiber from the fiber discharge portion 46 out of the 5 times. Although not shown in table 1, when the taper angle θ is smaller than 10 °, the good performance of the lint discharge is all determined as OK.
From the above verification results, the taper angle θ is preferably 10 ° or less from the viewpoint of the good properties of the filings discharged from the filings discharge portion 46.
Experimental example 2
In experimental example 2, the dimensions of the respective parts of the cyclone separator 30 were a=300.1 mm, b=90 mm, c=90 mm, d=30 mm, e=48 mm, f=170.1 mm, g=10 mm, i=21 mm, and only the taper angle θ was changed, so that the change in the flow rate of the air in the Y direction in the air discharge portion 50 and the change in the flow rate of the air in the Y direction in the lint discharge portion 46 were verified. The taper angle θ was verified at 10 °, 9 °, 7 °,5 °. The inner diameter h of the lint discharging portion 46 is determined by the taper angle θ. The flow rate of the air in the lint transfer pipe 11 was assumed to be 1000m/min, and the mass flow rate of the air at the inlet of the lint transfer pipe 11 was 0.014896kg/s.
As is clear from the verification result obtained in experimental example 2, if the flow rate of the air discharged from the lint discharging portion 46 increases, the flow rate of the air discharged from the air discharging portion 50 decreases, as shown in fig. 8, on the premise that the inner diameter e of the air discharging portion 50 and the inner diameter h of the lint discharging portion 46 are constant. Further, the flow rate of the air discharged from the air discharge portion 50 decreases as the taper angle θ becomes smaller. On the other hand, the flow rate of the air discharged from the lint discharge portion 46 branches off at a taper angle θ of 7 °, and is kept stable without decreasing even if the taper angle θ is further reduced. However, if the taper angle θ is reduced by setting the inner diameter e of the air discharge portion 50 and the inner diameter h of the lint discharge portion 46 to be constant, the Y-direction length f of the inclined portion 44 increases accordingly. It is considered that if the Y-direction length f of the inclined portion 44 becomes large, the Y-direction length a of the entire cyclone 30 becomes large, and the pressure loss becomes large. Therefore, if the taper angle is smaller than 7 °, it is considered that the ratio of the flow rate of the air discharged from the lint discharging portion 46 to the flow rate of the air discharged from the air discharging portion 50 becomes large. According to the findings of the inventors, if the flow rate of the air discharged from the lint discharging portion 46 is greater than the flow rate of the air discharged from the air discharging portion 50, the separation of the lint from the air cannot be performed satisfactorily. Therefore, the lower limit of the taper angle θ is preferably 7 ° or more.
From the results of the above experiments in experimental example 1 and experimental example 2, it is understood that the taper angle θ is preferably in the range of 7 ° to 10 ° (including the upper limit value and the lower limit value).
Experimental example 3
In experimental example 3, the relationship between the inner diameter h of the lint discharge portion 46 and the ratio of the flow rate of the air discharged from the lint discharge portion 46 to the flow rate of the air discharged from the air discharge portion 50 was verified. Further, as the air discharge portion 50, the air from which the lint is separated may be discharged to the outside air, and therefore, the inner diameter e of the air discharge portion 50 is set to be, for example, 48mm. As a result of the experiment, although not shown, the flow rate (absolute value) of air in the Y direction (negative direction) in the lint discharging portion 46 increases as the inner diameter h of the lint discharging portion 46 increases, and decreases as the inner diameter h of the lint discharging portion 46 decreases. On the other hand, the flow rate (absolute value) of the air in the Y direction (positive direction) in the air discharge portion 50 tends to be smaller as the inner diameter h of the lint discharge portion 46 becomes larger, and tends to be larger as the inner diameter h of the lint discharge portion 46 becomes smaller. As described above, according to the findings of the inventors, the inner diameter h of the lint discharging portion 46 is preferably smaller than the inner diameter e of the air discharging portion 50. However, it is found that when the inner diameter h of the lint discharging portion 46 is 27mm or less, it is difficult to discharge lint from the lint discharging portion 46. When the inner diameter h of the lint discharging portion 46 is 27mm, the ratio of the flow rate of the air discharged from the air discharging portion 50 to the flow rate of the air discharged from the lint discharging portion 46 is approximately 7 to 3. This ratio becomes smaller as the inner diameter h of the lint discharging portion 46 becomes larger. For example, in the range of 27mm to 35mm in the inner diameter h of the lint discharging portion 46, as the inner diameter h of the lint discharging portion 46 becomes larger, the ratio of the flow rate of air discharged from the air discharging portion 50 to the flow rate of air discharged from the lint discharging portion 46 becomes smaller. It is also understood that if the inner diameter h of the lint discharging portion 46 is 35mm, the ratio of the flow rate of the air discharged from the air discharging portion 50 to the flow rate of the air discharged from the lint discharging portion 46 is approximately one to one. As described above, if the ratio of the flow rate of the air discharged from the lint discharging portion 46 to the flow rate of the air discharged from the air discharging portion 50 becomes large, the separation of the lint from the air cannot be performed satisfactorily, and therefore, the inner diameter h of the lint discharging portion 46 is preferably 35mm or less.
The results of the above-described experimental examples 1, 2 and 3 were obtained by using 75 denier false twisted yarns as described above, and the present inventors have also made the same verification on other fibers. As a result, by forming the inclined portion 44 into a tapered shape having an angle in the range of 7 ° to 10 ° (including upper and lower limit values) with respect to the false twisted yarn, the polyester fiber, and the polyamide fiber, the lint can be separated from the air with high accuracy, and the lint discharge portion 46 can be prevented from being clogged with the lint, and the lint can be discharged from the lint discharge portion 46 satisfactorily. In particular, it was confirmed that remarkable effects were obtained for 75 to 450 denier false twisted yarns, 150 denier PET, and nylon.
