Camera 40 claps the twisting action of torsion device 14 to obtain the information of the coil of fiber 101,102 It takes the photograph, sends photographing information to the length detection portion 80a of control device 80 from camera 40 by signal wire 81.It is clapped in camera 40 When taking the photograph, in order to improve manufacture efficiency, such as will mark forming region 201 and non-formation region 202 is marked to be included in shown in Fig. 9 Interior mode is shot, and can successfully realize the length detection of many places.

Length detection portion 80a carries out image procossing to the image that camera 40 obtains, and extracts in multiple label forming regions 201 At least one of at least one and the non-formation regions 202 of multiple labels, detection label forming region 201 is at the center of coil The length of length and the non-formation region 202 of label on the central axis direction of coil in axis direction.Specifically, length detection Portion 80a carries out image procossing to the photographing information from camera 40, and the difference based on luminance difference or color extracts label shape respectively At region 201 and non-formation region 202 is marked, detects respective length 311,312, the respective length 311 that will test out, 312, which complete length Lt with scheduled torsion, is compared.It is set as here, length Lt is completed in the torsion for marking forming region 201 Scheduled 1st length L₁, the torsion for marking non-formation region 202 completion length Lt is set as scheduled 2nd length L₂.Have as a result, For body, in label forming region 201, by length 311 and scheduled 1st length L₁It is compared, is marking non-formation area In domain 202, by length 312 and scheduled 2nd length L₂It is compared.Compare in processing at this, until the length detected 311,312 length L is completed with scheduled torsion₁、L₂Until identical, rotating device 14m is controlled by control device 80, it is lasting to carry out The twisting action.If length L is completed in the length 311,312 detected and scheduled torsion₁、L₂It is identical, then pass through control dress 80 drivings for stopping rotating device 14m are set, torsion process S12 is terminated.This compares the feelings that processing is not in the given time Under condition, it is determined as that twisting action is abnormal by detection device 15, to 80 output error signal of control device, passes through control device 80 drivings for stopping rotating device 14m.As such abnormal example, shown in Fig. 6 B since the material of fiber or torsion are dynamic , there is the case where defective part 331 for not normally forming winding portion 102a in the undesirable condition etc. of work.Here, at adjacent two Mark the intermediate existing defects portion 331 in the non-formation region 202 of label between forming region 201.

As modified embodiment of the present embodiment, detection device 15 is not limited to the structure, can also by light sources such as laser, sweep The mechanism and optical receiving sensor for retouching light source are constituted.In such device, can by the light source to the fiber 101, 102 irradiations detect the label forming region 201 and mark the reflectivity or transmitance in non-formation region 202, thus count respectively It surveys the markd label forming region 201 of coating of the fiber 102 in the manufacture and the label of not no applying indicia is non-formation Length of the region 202 on long axis direction.

Control device 80 at least the label forming region 201 detected by detection device 15 coil central axis direction On length and scheduled 1st length L₁In identical situation, carry out torsion device 14 to adjacent with label forming region 201 The fiber 101 in the non-formation region 202 of label apply the movement of torsion.Alternatively, control device 80 is at least by detection device 15 Length and scheduled 2nd length L of the non-formation region 202 of label detected on the central axis direction of coil₂Identical feelings Under condition, torsion device 14 is made apply to the fiber 101 of the label forming region 201 adjacent with non-formation region 202 is marked The movement of torsion.Here, as an example, scheduled 1st length L₁For 10mm, scheduled 2nd length L₂For 20mm.In addition, conduct An example, the number of winding portion 102a are 37 relative to every 1cm coil-like fiber.

Specifically, control device 80 respectively with the driving device 10m of roller 10, the 1st keeping body 30 driving device 30m and Mobile device 30g, the label driving device 29m of apparatus for coating 29, the rotating device 14m of torsion device 14, the 2nd keeping body 50 Driving device 50m and camera 40 connect, and independently action control are carried out to each device or component, so as to implement line The manufacturing method of ring-shaped fiber.

As an example, the predetermined time after since the movement for applying torsion to the fiber 101 marked in forming region 201 In (such as 2.5 seconds), length of the label forming region 201 detected by detection device 15 on the central axis direction of coil is not Equal to scheduled 1st length L₁In the case where, the movement that control device 80 makes torsion device 14 apply torsion stops.This means that Exception has occurred in twisting action, generates the defective part 331 that winding portion 102a etc. can not be formed applying and reversing (referring to figure 6B), it needs to stop manufacturing process, carries out removing the replies appropriate such as defective part 331.

Alternatively, the predetermined time after since the movement for applying torsion to the fiber 101 marked in non-formation region 202 In (such as 2.5 seconds), length of the non-formation region 202 of label detected by detection device 15 on the central axis direction of coil Not equal to scheduled 2nd length L₂In the case where, the movement that control device 80 makes torsion device 14 apply torsion stops.This with it is upper State situation similarly, it is meant that exception has occurred in twisting action, and winding portion 102a etc. can not be formed applying torsion by generating Defective part, need to stop manufacturing process, carry out removing the reply appropriate such as defective part.

Fiber 1 be before applying indicia in the state of at least one fiber, be before implementing coil without applying Fiber in the state of torsion.The fiber 1 is that flexible fiber can be carried out by heat, this is displacement is big or material Stablize and can cheaply obtain etc. preferably, is also possible to be stretched by applying voltage as piezopolymer The fiber of contracting.As the example that can carry out flexible fiber by heat, there is polymer fiber.For example, fiber 1 can be with A fiber made of straight-chain low density polyethylene (LDPE) is constituted.Material in addition to this, such as poly- second also can be used in fiber 1 Alkene (low density polyethylene (LDPE), straight-chain low density polyethylene (LDPE), high density polyethylene (HDPE)), nylon (nylon 6, nylon 6,6, nylon 12 Deng), PVDF, polyester or elastomer (silicon rubber).

Hereinafter, referring to Fig. 7 A~Fig. 7 C, to the manufacturing method for being able to use the coil-like fiber that the manufacturing device is implemented It is illustrated.

Fig. 7 A indicates flow chart relevant to the coilization of fiber 101 in torsion section 91.

As shown in Figure 7 B, the manufacturing method of coil-like fiber can be also equipped with the process (S12) to 1 applying indicia of fiber. In this case, the manufacturing method of coil-like fiber, which is also equipped with, is coated with the work that the fiber 101 of label is conveyed to torsion section 91 Sequence (S13).

In addition, the manufacturing method of coil-like fiber as seen in figure 7 c, can have to label coating cloth deck 20 as an example The process (S11) of conveying fiber.

Firstly, as depicted in figs. 1 and 2, by driving device 10m, revolve roller 10 clockwise shown in the arrow 11 Turn, in linkage with this, rotates the direction shown in the arrow 71 of cylinder 70 by rotating device 70m, fiber 1 is applied to label The label coating cloth deck 20 of cloth apparatus 29 conveys (S11).

Then, it by mark part is coated on fiber 1 (S12) as follows.By driving device 29m, have multiple It marks the support 21 of coating part 22 to drive upside down relative to label coating cloth deck 20, thus to 1 applying indicia of fiber, is formed simultaneously Multiple label forming regions 201 and the non-formation region 202 of label shown in Fig. 5 A.This drives upside down carries out in the following manner: Drive control is carried out to driving device 29m by signal wire 81 by control device 80.At this point it is possible to stop the conveying of conveying device 12 Fiber 1 presses fiber 1 multiple label coating parts 22, thus applying indicia.It can also replace, in control device 80 Control under, label coating part 22 is pressed to fiber 1 on one side, on one side by 12 conveying fiber 1 of conveying device, thus coating mark Note.

It is shown in Fig. 5 A to 1 applying indicia of fiber and forms multiple fibers 101 for marking forming regions 201.I.e., described Label is applied with length shown in 301, forms label forming region 201, the interval of adjacent label forming region 201 is vacated Mark the length 302 in non-formation region 202.

In order to keep the coating method of the label as simple as possible or simplify aftermentioned image procossing, preferred length 301 With length 302 respectively in the fiber entirety it is identical, i.e., 22 arranged at equal intervals of label coating part, even if the length Degree 301 and length 302 are uneven, will not lose the effect of embodiments of the present invention.Hereinafter, as an example, being set as length 301 and length 302 distinguish it is identical.

In terms of being easy coating or easily identifying, label used in the label coating part 22 is preferably the depth of oiliness Color ink is also possible to aqueous ink but if fiber 101 does not repel coating.In addition, if utilizing ultraviolet light in the detection of label Light color or transparent fluorescent paint then also can be used in the fluorescence developing of irradiation.

Furthermore it marks forming region 201 corresponding with either in the 1st region or the 2nd region, marks non-formation region 202 is corresponding with another party.Above-mentioned coating method, such as can use and mark the surface color and the 2nd region for making the 1st region Surface color is different.

After the fiber 101 progress coil is configured to coil-like fiber 102, in order to no matter from coil-like fiber 102 which direction observation can identify the label, entire circle of the label preferably over the coil-like fiber 102 Week is coated.I.e., as an example, by marking apparatus for coating 29, in the whole circumference applying indicia of fiber 101, mark is formed Remember forming region 201.In this case, when the diameter of the coil-like fiber 102 is set as D (referring to Fig. 6 B), the label Length 301 of the forming region 201 on long axis direction is more preferably at least (D × π), in other words, at least described coil-like fiber About 3 times or more of 102 diameter, but in the case where coil-like fiber 102 is the transparent body, it is not so limited.In addition, long Degree 301 can be at least { D × π × (1/2) }, in other words, at least more than (D × 1.5).

In the case where carrying out the detection of the label forming region by image procossing, only clapped from a direction It takes the photograph.At this point, if label is coated with more than at least half of circumference of coil-like fiber, in the line described from a direction When ring-shaped fiber, the label Hide All situation as the back side of coil-like fiber 102 that will not be coated with necessarily can At least part of label is enough taken, therefore length 301 is { D × π × (1/2) } or more.

Here, in order in the whole circumference applying indicia of fiber 1, will label coating part 22 is .ed while pressing to fiber 1 Front side and inboard alternately movement to the paper vertical direction of Fig. 1, thus fiber 1 is revolved in label 20 Co-coercivity of coating cloth deck Turn, it being capable of whole circumference applying indicia to fiber 1.In this case, the manufacturing device of coil-like fiber has for that will mark The driving devices (not shown) such as the front side of coating part 22 to the paper vertical direction of Fig. 1 engine mobile with inboard.Alternatively, will The support 21 for having label coating part 22 for example configures 2 groups in a manner of opposing upper and lower, sandwiches fiber 1 with 2 groups of supports 21, Thus, it is possible to the whole circumference applying indicias to fiber 1.

Then, as shown in Figure 2 to 3, it is coated with markd fiber 101, torsion section 91 is delivered to by conveying device 12 (S13).At this point, under the control of control device 80, the clockwise rotation shown in the arrow 11 of roller 10 stops, and stops fine The conveying of dimension 101.

Then, in order to which the torsion section 91 for providing to apply the fiber 101 of torsion is protected as shown in Fig. 2 and Fig. 8 A by the 1st Body 30 and the 2nd keeping body 50 is held to sandwich the fiber 101 for applying the section 91 of torsion and keep (S14).1st keeping body 30 and Section 91 between 2 keeping bodies 50 is the section for being applied torsion.

As shown in Figure 8 B, rotating device 14m is controlled by control device 80, the section 91 for applying the torsion is applied and is turned round Turn, starts the coil (S15) of fiber 101.Fig. 8 B is the amplification of part corresponding with part B enclosed by the dotted line in Fig. 8 A Figure.

At this point, for example shown in Fig. 8 B, in the case where the length detection in forming region 201 is only marked, in label shape When at starting coil in the 201a of region, as shown in Figure 8 C, the length 311 of the label forming region 203 after detection coil (S16).It, can also be with furthermore the processes (S15) of torsioned fibres 101 and the process (S16) for detecting length 311 can successively be implemented Implement simultaneously.

The length 311 that be will test out by length detection portion 80a and scheduled 1st length L₁It is compared (S17).

In the given time, the length 311 detected is equal to scheduled torsion and completes length L₁In the case where (S17；It is), Whether the whole coilization for judging to reverse the fiber 101 in section 91 completes (S18).

(the S18 in the case where coilization is not completed；It is no), it continues to reverse in this state, as in fig. 8d, Start coil (S15) in the non-formation region 202a of the label adjacent with the label forming region 203 after coil.

(the S18 in the case where coilization is completed；It is), terminate the processing of coil.

On the other hand, in the given time, as illustrated in fig. 8e, the mark after 80a is judged as coil in length detection portion Remember that the length 311 of forming region 203 is not equal to scheduled 1st length L₁In the case where (S17；It is no), stopped by control device 80 Spin-ended rotary device 14m stops twisting action (S19).

The length 311 of the label forming region 203 after coil can effectively be made in this way becomes scheduled 1st length L₁。

In addition, another example of the process (S16) as detection length 311, such as non-shape is only marked as shown in Figure 8 F In the case where at the length detection in region 202, when starting coil in marking non-formation region 202a, as shown in fig. 8g, By length detection portion 80a the length 312 in non-formation region 204 and scheduled 2nd length L will be marked after coil₂Into Row is relatively (S17).

Fig. 8 F is the enlarged drawing of part corresponding with the part F surrounded in Fig. 8 A by a chain-dotted line.In the given time, The length 312 detected completes length L not equal to scheduled torsion₂In the case where (S17；It is), judge to reverse in section 91 Whether the whole coilization of fiber 101 completes (S18).

(the S18 in the case where coilization is not completed；It is no), it continues to reverse in this state, as illustrated in figure 8h, Start coil (S15) in the label forming region 201b adjacent with the non-formation region 204 of label after coil.

On the other hand, in the given time, as shown in fig. 81, after being judged as coil by length detection portion 80a The length 312 in the non-formation region 204 of label be not equal to scheduled 2nd length L₂In the case where (S17；It is no), it is filled by control It sets 80 to stop rotating device 14m, stop twisting action (S19).

The length 312 in the non-formation region 204 of label after coil can be effectively set to become the scheduled 2nd so long Spend L₂。

In addition, another example of the process (S16) as detection length 311, such as in forming region 201 is marked Length detection and in the case where marking length detection this two side in non-formation region 202, starts in label forming region 201 When coil, as illustrated by figure 8j, by length detection portion 80a by the length 311 of the label forming region 203 after coil with Scheduled 1st length L₁It is compared, on the other hand, when starting coil in marking non-formation region 202, such as Fig. 8 J institute Show, the length 312 in non-formation region 204 and scheduled 2nd length L will be marked after coil by length detection portion 80a₂ It is compared (S17).Movement after respectively is as previously described.

The length 311 of the label forming region 203 after coil can effectively be made in this way becomes scheduled 1st length L₁, and the length 312 in the non-formation region 204 of label after coil is made to become scheduled 2nd length L₂。

Like this, in section 91, forming region 201 is continuously and alternately marked and marks non-formation region 202 Coil.

After the coilization in section 91 is completed, as shown in Fig. 8 K and Fig. 8 L, the guarantor of the 2nd keeping body 50 is released It holds, starts the conveying of the fiber 101.At this point, the 1st keeping body 30 is in a manner of synchronous with the conveying since mobile Position I is moved to mobile end position II, stops the conveying.Fig. 8 L indicates the state after conveying.

When the 1st keeping body 30 is moved to mobile end position II from mobile starting position I, if controlled, The relaxation of torsion section 91 for not making fiber 101, limits fiber 101 downstream by keeping the 1st keeping body 30 of fiber 101 Movement, then can torsion section 91 to fiber 101 apply tension.At this point, in order to become the tension of setting, by control device 80 feed back tension by signal wire 81 always.Specifically, for example in the 1st keeping body 30 or the keeping body pair of the 2nd keeping body 50 A side connection or built-in weighing sensor, thus, it is possible to measure tension.The weighing sensor is filled via signal wire and control 80 connections are set, the setting and control of tension are carried out by the control device 80.As control method, such as PID control can be enumerated System.It is reversed to apply to fiber 101, in the 1st keeping body 30 and the 2nd to play a role to an example for applying component as tension In the state that the fiber 101 in the section 91 between keeping body 50 applies tension, the 2nd keeping body 50 and by coil-like fiber 102 cylinders 70 and guiding piece 72 batched, by rotating device 14m, as shown in arrow 51,71,73, all with the same direction And identical rotation speed rotation, carry out twisting action.As long as these components are all the same direction, its rotation side is not limited To.In addition, direction of rotation and the speed of rotating device 14m, are controlled by control device 80 by signal wire 81.

Twisting action in this way, the fiber 101 between the 1st keeping body 30 and the 2nd keeping body 50 are twisted, such as Fruit is more than a certain number of torsions, then fiber 101 cannot keep linear, is deformed into coiled type by starting point of certain, becomes line Ring-shaped fiber 102.The starting point depends on the uniformity etc. of tension or the fiber 101 itself, sometimes also using many places as starting point. As the coilization of fiber 101 carries out, the 1st keeping body 30 and the length in the section 91 of the 2nd keeping body 50 shorten, therefore the It is moved by mobile device 30g in direction shown in arrow 31 of 1 keeping body 30 along Fig. 2.At this point, being begun by control device 80 Feedback tension eventually, so that tension is constant all the time as setting value.

Hereinafter, being illustrated in detection device 15 according to the method for the carry out degree of spectral discrimination coil.

If the coilization of fruit fiber 101 carries out, then coilization can be on the long axis direction of fiber 101 from the coil Starting point starts to carry out.Fig. 6 A shows the ongoing fiber 102 of coilization.Coil is carried out from the right side of Fig. 6 A side direction to the left To the position as shown in reference marker 303, if further applying torsion, coilization can from 303 position to a left side of Fig. 6 A Side direction carries out.

At this point, being for example conceived to the non-formation region 202A of label of the ongoing not applying indicia of coilization, coil The length in the non-formation region 202 of label before is identical as the length 302 in the non-formation region 202 of label shown in Fig. 5 A, but With the beginning of coil, the length in non-formation region 202 is marked proportionally to shorten with rotation speed, the final label is non- Constant about 1/3 length for the length 302 before coil of the length 304 of forming region 202A.I.e., the length 302 About 1/3 length becomes torsion and completes length Lt.As a result, by the length 304 of the non-formation region 202A of marker for determination whether Length Lt is completed as torsion, can determine whether twisting action is completed by length detection portion 80a.

While the length 304 of the non-formation region 202A of label becomes torsion completion length Lt, with the non-shape of label The beginning is melted at the coil of region 202A adjacent label forming region 201A, length 305 as described above, is shown from Fig. 5 A The length 301 of label forming region 201 out foreshortens to its about 1/3 length and reverses completion length Lt.It marks non-formation It is identical as marking the torsion of forming region 201A to complete length Lt that length Lt is completed in the torsion of region 202A.Therefore, pass through camera The 40 and length detection portion 80a of control device 80 monitors the length of each region 201,202, can track the fiber 101 The progress of coil in all sections can identify the completion of the coil in each region 201,202.

At this point, the change rate of the length in order to accurately confirm each region 201,202, need to make the region 201, 202 length is sufficiently small.The effect of embodiments of the present invention in order to obtain, although will receive the resolution of aftermentioned filming apparatus Interference etc. caused by the vibration of rate or device itself influences, but preferably up to several cm of the length in the region 201,202 or so. On the contrary, if the length in the region 201,202 is too short, processing capacity needed for needing to increase aftermentioned image procossing, Or it reduces and the length of torsion disposably is applied to the fiber, slow down manufacturing speed, therefore not lose reality of the invention The degree for applying the effect of mode reduces the length in the region 201,202.

Like this, by the graphics process of the length detection portion 80a, determining the 1st keeping body 30 and the 2nd keeping body 50 Between coilization while complete (i.e., torsion complete), pass through control device 80 and stop the 2nd keeping body 50,70 and of cylinder The rotation of guiding piece 72.

As shown in figure 3, the 2nd keeping body 50 is separated with fiber 101, rotate roller 10 and cylinder 70, in the 1st keeping body Conveying fiber 101 in the state of 30 gripping fibers 101 batches the fiber 102 after the completion of coil on cylinder 70.It is controlling Under the control of device 80 processed, when the 1st keeping body 30 is moved to the 2nd keeping body 50 and is clamped with the mobile end position II of fiber 101, The rotation of stop roller 10 and cylinder 70, as shown in figure 4, make the 2nd keeping body 50 be moved to Fig. 1 the 1st keeping body 30 position Move starting position I, the 2nd keeping body 50 gripping fibers 101 again.It through this structure, can be always by stay in grade Coil-like fiber conveyed and batched, even therefore long fiber, can also obtain the uniform line of whole number of torsions Ring-shaped fiber.

By the way that the above process is repeated, even long fibre, also can automatically be carried out with uniform number of torsions Coil.

(embodiment)

Hereinafter, embodiments of the present invention are described in detail referring to embodiment.

The production method of coil-like fiber is illustrated.

Firstly, making high-intensitive straight-chain low density polyethylene (LDPE) (hereinafter referred to as LLDPE) fiber according to the following steps.It will The LLDPE (blocky, to buy from Sigma-Aldrich) that density is 0.918g/cc is put into heating melting extruder, heats It is 220 DEG C, after being kept for 30 minutes, is squeezed out from the nozzle that diameter is 1mm, the fiber for becoming Filamentous is wound on roller.

Then, the fiber of the LLDPE batched is stretched between two rollers that can adjust revolving speed, places add between the rolls Heat is 80 DEG C of heating plate, in a manner of the fiber and contact heater plate that stretch between the rolls, fibre that will be released from the roller of a side Dimension, stretches while being batched by the roller of another party.The diameter of roller is 5cm, and the revolving speed for releasing roller is set as 2rpm, work beam Revolving speed be set as 20rpm, be stretched as 10 times, obtain fiber.

Then, for the fiber after stretching, an example as label uses black felt pen (the タミヤ coating mark of oiliness Note X-1) label of 3cm is coated on to the whole circumference of fiber on the long axis direction of fiber, and area is formed as label Domain.Label forming region is vacated the interval 3cm (in other words, the length in non-formation region being marked to be set as 3cm) each other, is coated with shape At multiple label forming regions.

Then, coil-like fiber is processed.The load of 25g is applied to the fiber for being coated with label and with per second 5000 The revolving speed of degree is twisted, and coil-like fiber is obtained.By twisting, fiber reverses in the state of keeping linear, if turned round Going to the twisting count of the standardized unit fibre length of the rugosity of fiber is 0.23 to turn left the right side, then fiber cannot keep linear, It can occur Texturized for coiled type.The coil melt begin needed for number of torsions can be different according to the rugosity of fiber, this at It is usual rugosity there are in the stretching fiber of a degree of irregular unevenness, only can not determines that coilization is completed by the length of fiber The reason of required number of torsions.Fiber increases by one turn whenever twisting count, and coil will reverse a circle (i.e., 1 winding portion).

The state of coil is shot by video camera.The fiber 103 of Fig. 9 be coil during fiber image. Coil proceeds to the position as shown in 306, if further progress is twisted, coilization can be carried out to the left direction of Fig. 9. Here, the label forming region in Fig. 9, in the length 307 and coil of the non-formation region 202B of label after coil Length 309 of the length 308 of 201C as the non-formation region 202D of label before coil.Here, being conceived to the non-shape of label At region 202B, label forming region 201C and non-formation this three of region 202D of label, these areas are shot at predetermined time intervals Domain.Then, image procossing is carried out to the image of shooting (i.e. image), finds out the variation that the length of each region is passed through at any time. Figure 10 is the chart of the length 307,308,309 for indicating described region 202B, 201C, 202D and the relationship of time.Coilization it The length 307,308,309 of preceding region 202B, 201C, 202D respectively 3cm marks non-formation region first in the time 401 The coil of 202B melts the beginning, and the length 307 of non-formation region 202B is marked linearly to shorten, the time after about 2.6 seconds 402, length 307 shorten to 1cm, is no longer changed later.Therefore, when which is 1cm, length is completed for torsion Lt.At the same time, the coil of forming region 201C is marked to melt the beginning.Therefore, in the time 402 it can be determined that marking non-formation area The coilization of domain 202B is completed.This means that can be determined that if the length in the region becomes torsion and completes length Lt to turn round Turn to complete.Furthermore in the time 403, the image of shooting is equivalent to Fig. 9.

By proceeding as described above in entire section, the completion of the coil in entire section can be judged (in other words as line The manufacture of ring-shaped fiber 102 is completed) and conveying start.

(effect of embodiment)

According to the embodiment, detection applies label forming region 201 or label non-formation region 202 after torsion The region for being applied with torsion length, if the length detected and scheduled length L₁Or L₂It is identical, then it can terminate to reverse Movement, starts the torsion in adjacent region.As a result, it is possible to stable and fully automatically manufacture coil number of torsions is uniform The coil-like fiber 102, the efficient activity that can be realized the raising of yield rate and manufactured by full-automatic bring.
