Carry out the displacement action of displacement roller 20,21.Using displacement roller 20,21 guide line materials 10 relative to spool 11,12 batch and
It releases.If the velocity of displacement (movement speed of the displacement roller 20,21 relative to spool 11,12) of displacement roller 20,21 is high speed,
Then wire rod 10 becomes low-density relative to batching for spool 11,12, if velocity of displacement is low speed, wire rod 10 is relative to volume
Batching for spool 11,12 becomes high density.
In rack and along the wire rod 10 extended between each roller for machining 15 and corresponding displacement mechanism 18,19
Walking path position on be supported with elasticity adjusting mechanism 24,25.It is revolvably propped up respectively on elasticity adjusting mechanism 24,25

It is linked with the elastic adjusting motor 28,29 for the control for being controlled device 41.Also, pass through elastic adjusting motor 28,29
Action, assign tension via 26,27 pairs of wire rods 10 of dance roller, and the tension power of wire rod 10 is conditioned.Elastic tune
Section mechanism 24,25 is respectively arranged with pressure sensor 30,31, and pressure sensor 30,31 is by for the tension progress to wire rod 10
The compositions such as the load cell of detection.It will indicate that the detection data of wire tension is input to control from the pressure sensor 30,31
Device 41 and wire tension is adjusted to appropriate value, and the rotation of the motor 16 of the 1st, the 2nd spool 11,12 is controlled,
It is conditioned to the rotary speed of spool 11,12.As a result, with spiral barrel dliameter, to batch the size of diameter unrelated, wire rod 10 with
Constant speed is walked.
Between each dance roller 26,27 and corresponding roller for machining 15 and the position near roller for machining 15
It is revolvably configured with guiding rod 32, guiding rod 32 is used for the walking of guide line material 10.
Then, the effect of the wire saw of present embodiment is illustrated.Wire saw is by the control of control device 41
It is acted.Control device 41 is constituted such as by the processing circuit including computer and memory, according to being stored in memory
Program control the various actions that are executed by wire saw.
When carrying out the cutting off processing of workpiece 200, with the reciprocal walking of wire rod 10, by the driving of displacement motor 22,23,
Displacement mechanism 18,19 carries out displacement action along the axis of spool 11,12.Pass through the action of displacement mechanism 18,19, wire rod 10
It is controlled in a manner of being batched in spool 11,12 by setting spacing, and the wire rod 10 is guided, so that wire rod 10 is from volume
The releasing of spool 12,11 is smooth.In this case, appropriate tension is assigned to wire rod 10 by elasticity adjusting mechanism 24.
Also, as described above, wire rod 10 conveys go to running stroke every time with the progress of the cutting off processing of workpiece 200
Length alpha and the poor γ for returning to running stroke length β, while each section is used for multiple times in cut-out.Also, in the present embodiment,
By the control of control device 41, the length of nonexpondable difference γ used part with narrow spacing (such as with wire rod
The equal spacing of 10 diameter) and batched in the 2nd spool 12 with high-tension.This is using referring to partly：Cut-out is used in add
The part of the pre-determined multiple access times of work, and batched after the 2nd spool 12 without using in the portion of cutting off processing
Point.
It is said below according to flow chart shown in fig. 6 to batching action described in being carried out under the control of control device 41
It is bright.
In the present embodiment, before work pieces process, the state to be rolled onto the 1st spool 11 from end side prepares not used line
Material 10, the part for being used in the used wire rod 10 of work pieces process are wound to the 2nd spool 12 from starting end side.It is preferred that not
The wire rod 10 used is wound in the 1st spool 11 with the spacing bigger than the diameter of wire rod 10.Flow chart shown in fig. 6 indicates the 2nd
The action of spool 12, displacement mechanism 19 corresponding with the 2nd spool 12 and elasticity adjusting mechanism 25.
As shown in fig. 6, in step (hereinafter referred to as S) 1, wire rod 10 goes to walking to start.Walking is gone to open with this
Begin, in S2, elasticity adjusting mechanism 25 assigns high-tension to wire rod 10.In addition, it is performed simultaneously S3 after s 2 or with S2,
In S3, roller 21 temporarily from wire rod 10 leave by (such as can be less than 1 second), so that the tension that elasticity adjusting mechanism 25 assigns transmits
To the wire rod 10 extended between dance roller 27 and the 2nd spool 12, that is to say, that so that the roller 21 of displacement mechanism 19
The transmission of tension is not hindered, and then roller 21 returns to original position (position contacted with wire rod 10).That is, making the (tool of displacement mechanism 19
Body is roller 21) it is moved in a manner of leaving or reducing the contact between wire rod 10 from wire rod 10, by displacement mechanism 19
Effect (function) temporarily release or make its decline.In S4, the movement speed of displacement mechanism 19 is set as low speed.Therefore,
Walking, wire rod 10 is gone to be wound in the 2nd spool 12 with high-tension and with narrow spacing with wire rod 10.In this embodiment party
In formula, in S1~S4, wire rod 10 is batched with the spacing equal with its diameter.
Then, in S5, the data of the accumulative rotation amount based on roller for machining 15 judge the length of the poor γ of wire rod 10
Whether partial batching terminates, and in the case where being not over, repeats the judgement of S5.Here, wire rod 10 go to walking before
The length of the poor γ on head point is the difference gone to running stroke length alpha and return to running stroke length β, and it is reciprocal to be equivalent to wire rod 10
Mobile primary delivered length.This goes to the front part of walking not released after the 2nd spool 12 batching, and becoming has made
With part, so cutting off processing will not be used in.
In the judgement of S5, being judged as using part relative to the 2nd spool 12 in the case of batching end,
In S6, using elasticity adjusting mechanism 25 by the tension recovery of wire rod 10, in S7, the velocity of displacement of displacement mechanism 19 is set as high
Speed.In this state, wire rod 10 go to walking continue, therefore wire rod 10 it is predetermined using part with wide spacing and with low-tension
It batches in the 2nd spool 12.Predetermined use partly refers to the part for not reaching pre-determined access times.Wherein, exist
The starting end side of wire rod 10 being connect with the 2nd spool 12, initial goes in running stroke length alpha the portion that will be equivalent to poor γ
The part (that is, returning to part of running stroke length β) of removal gained is divided not reach pre-determined access times
During as use part processing.
In S8, being judged as going in the case of going to walking to terminate of running stroke length alpha amount, in S9, wire rod
10 are switched to return walking, are accompanied by this, and wire rod 10 is set as low-tension in S10, and displacement mechanism 19 is set as high in S11
Speed.Therefore, the wire rod 10 on the 2nd spool 12 is batched with wide spacing to be successfully easily released.Then, in S12,
In the case of being judged as that the return walking for returning to running stroke length β amounts terminates, judge that the cut-out of workpiece 200 adds in S13
Whether work terminates, and S1 is returned in the case where cutting off processing is not over.In S13, terminate in the cutting off processing of workpiece 200
In the case of end processing.
In this way, wire rod 10 is batched with high density in the 2nd spool 12 using part, therefore can prevent from making a reservation for use portion
The wire rod 10 divided enters between the wire rod 10 for having used part.In addition, when the moving direction of displacement mechanism 19 is in wire rod 10
When being inverted in the predetermined way batched with wide spacing using part, then it is overlapped and is rolled up with wide spacing on the wire rod 10 wound with wide spacing
Around wire rod 10.In this case, the reel-up of wide spacing only has one layer, therefore does not lead to the problem of substantially.
In addition, in the 1st spool 11, wire rod 10 is batched and is released with low-tension and carried out with high-speed displacement.Therefore,
In the 1st spool 11, wire rod 10 is batched with low-tension and with wide spacing, and is put with velocity of displacement corresponding with the spacing
Go out." thin space " in present embodiment refers to batching spacing (wide spacing) as benchmark spacing using part by predetermined
In the case of it is narrower than the benchmark spacing.Equally, " high-tension " in S2 refers to that the low-tension in S6 (is being made a reservation for the volume using part
Tension when taking) as higher than the basal tension in the case of basal tension.In addition, " low speed " in S4 refers to will be in S7
Speed when batching of part (predetermined use) is used as in the case of reference speed than the reference speed low speed at a high speed.
Therefore, it has the following effects that in the present embodiment.
(1) wire rod 10 using part with the spacing equal with the diameter of wire rod 10, i.e. with than wire rod 10 it is predetermined use portion
Narrow spacing is divided to be batched to high-density in the 2nd spool 12.Therefore, it is avoided that the predetermined using partly by spiral of wire rod 10
Cylinder batching and enter using between part or with release and deviate from between the wire rod using part.Therefore,
It is avoided that caused by 10 mutual contact of wire rod and makes a reservation for the Grain Falling Off using part, wire rod damage, and can prevent
The big tension change generated with the releasing of wire rod 10.In this way, because can be by wire rod 10 using partly suitably rolling up
Around the 2nd spool 12, so energy is efficient and efficiency carries out cutting off processing to workpiece 200 well.
(2) wire rod 10 using being partly not only wound to the 2nd spool 12 with thin space, but also batched with high-tension,
Even if therefore predetermined be wound to if having used on part using part can more reliably avoid predetermined entered using part from making
With between the wire rod 10 of part.Therefore, it is avoided that the harmful effect of the cutting off processing for workpiece 200, can be accurately proceed
Processing.
(3) because being wound in the 2nd spool 12 using part with thin space and with high density, even if in wire rod 10
It is batched in the state of the 2nd spool 12 throughout its overall length, is also avoided that the volume that stores of wire rod 10 becomes larger.Therefore, such as Fig. 1 institutes
Show, for the 2nd spool 12 compared with the 1st spool 11, the size of at least one party in the axis direction length and diameter of reeling end can
To reduce.Therefore, the 2nd spool 12 can be formed as to small-sized, light weight, wire saw becomes relative to the handling of the 2nd spool 12
It is easy, and convenient for the carrying of the 2nd spool 12 and keeping etc..
(4) wire rod 10 it is predetermined using part to batch spacing wider than having used part, therefore this can be reduced and predetermined use part
Mutual contact.Grain Falling Off, wire rod damage can be reduced as a result,.
(the 2nd embodiment)
Then, the 2nd embodiment of the present invention is illustrated based on Fig. 7.
In the 2nd embodiment, wire rod 10 goes to the stroke length α of walking equal with the stroke length β for returning to walking.And
And it if wire rod 10 back and forth reaches defined limited number of times (last time), is used as and has used part in the 2nd spool 12
On batch the stroke length α amounts for going to walking.
That is, execute stroke length α in S21 goes to walking, the return that stroke length β is executed in S22 is walked.
S21's goes in walking and the return of S22 walking, keeps the tension of wire rod 10 and velocity of displacement equal, and velocity of displacement is set
It is set to so that wire rod 10 is batched with the spacing wider than its diameter.Also, in S23, when judging that reciprocal time has reached
When limited number of times, then further start stroke length alpha in S24 goes to walking.At this point, in S25, wire tension ratio S21
Be set to height when going to walking.Then in S26, the roller 21 of displacement mechanism 19 temporarily leaves from wire rod 10.Then, in S27
In, the speed of displacement mechanism 19 is switched to low speed when going to walking than S21.As long as the speed of the displacement mechanism 19 of S27 is set
To make wire rod 10 be batched with the spacing equal with its diameter.It is narrow when used wire rod 10 is with than cutting off processing as a result,
It narrow spacing and is batched in the 2nd spool 12 with high-tension.
In the case of being judged as that reciprocal time does not reach limited number of times in S23, or it is judged as in S28 going to row
In the case of walking end, judge whether the cutting off processing of workpiece 200 terminates in S29.Cutting off processing is not in S29
In the case of, return to S21.In the case that the cutting off processing of workpiece 200 terminates in S29, end processing.Therefore, wire rod 10 is limiting
After the reciprocal walking of number processed, stroke length amount has used winds portions in the 2nd spool 12.
Therefore, effect in a same manner as in the first embodiment can be also obtained in the 2nd embodiment.
(other embodiment)
The present invention is not limited to the described 1st, the 2nd embodiments, can also embody in the following manner.
In the described 1st, the 2nd embodiment, batched with the spacing equal with the diameter of wire rod 10 using part, but
It is will using the 1.1 times of degree of part batched spacing and be set as such as diameter of wire rod 10, part can also to be used by predetermined
Spacing of batching be set as spacing more than 1.1 times.In short, making using part to be rolled up than predetermined the batch spacing small using part
It takes.
By wire rod 10 using partly batching in the case of, the tension of wire rod 10 is set as and tension phase before this
Same tension.That is, to execute batching using part using the identical tension that batches of part with predetermined.
