Among Fig. 8, the 4th, multiaxis device 1 is employed cutter when changing spool, the 5th, used crimping roller when multiaxis device 1 changes spool, 6 are arranged on the bonds such as two sides adhesive tape on the uncoiling top lateral surface of the band 30 of being reeled on the new axle 3, the 7th, in the uncoiling side tenslator 47 shown in Fig. 1 with detect that tension force and uncoiling side set that computing is carried out in the corresponding Torque Control output of difference of tension force and to the Torque Control output arithmetic unit of magnetic powder brake 1e or magnetic powder brake 1f output.The 8th, set the uncoiling sides for uncoiling side tension controller 47 by the operator and set the tension force setting apparatus that tension force are used, the 9th, band 30 transmit old axle 2 revolutions 1 in the action change the detected portion 1h of the detected portion 1g that detects magnetic powder brake 1e or magnetic powder brake 1f and convert to electric signal to coil diameter detecting device 10 and programming controller 11 outputs near cycle detecting devices such as switches.

Coil diameter detecting device 10 preestablishes the thickness of band 30 for example and is wound on the beginning diameter of band 30 maximum gauges on the old axle 2, to the old axle 2 per 1 from cycle detection device 9 transfer into pulse signal count, according to its accumulative total and beginning diameter calculate with band 30 emit and the coil diameter of the old axle 2 that reduces, as detecting coil diameter, and an electric signal suitable with the coil diameter of being calculated exports in the programming controller 11.

Programming controller 11 is for using the programming controller of microcomputer, and it is according to the spinning movement of predefined control sequence to revoliving arm 1c, and the action etc. of depressing of the cut-out action of cutter 4, crimping roller 5 is controlled.

Below, the axle that changes that above-mentioned multiaxis device 1 is described with reference to Fig. 9 moves, band 30 is being transmitted the course of action to the reel spool shown in Fig. 7 33 from old axle 2, programming controller 11 sets by coil diameter that coil diameter detecting device 10 is detected and the predefined axle that changes that a coil diameter compares and send the signal that expression prepares to change axle to multiaxis device 1 during changing axle, drives to be contained in the motor that is provided with among the pedestal 1a so that revoliving arm 1c rotates (referring to step 901 among Fig. 9).

Rotate owing to revoliving arm 1c make old axle 2 cross from position shown in Figure 8 output shaft 1b directly over along a circular arc to the process of a relative side shifting, make by means of the driving of the rotation of revoliving arm 1c and transfer roller 38 band 30 from the old axle 2 with more discharge capacity discharging in the unit interval of turning round than usual, supporting by guide roller 1d to the old axle 2 of a relative side shifting and the band 30 between the uncoiling side measuring roll 36.

And, because revoliving arm 1c rotation, new axle 3 from the position of Fig. 8 by under the output shaft 1b along circular arc to an opposite side shifting, when the approaching above-mentioned guide roller 1d of outer peripheral face of the band 30 on being wound on this new axle 3 and the band 30 between the uncoiling side measuring roll 36, programming controller 11 is received the signal that detects new 3 outer peripheral face that for example transmits from sensor not shown in the figures, perhaps, above-mentioned guide roller 1d that calculates with the angle of revolution of revoliving arm 1c and the band between the uncoiling side measuring roll 36 detect the interval between band 30 and new 3 outer peripheral face to the difference of the beginning diameter of distance between the center of new axle 3 and predefined new axle 3, when this is spaced apart the setting interval, programming controller 11 makes the motor of multiaxis device stop to drive, revoliving arm 1c stop the rotation and make the outer peripheral face of new axle 3 be configured in band 30 from old axle 2 transmits be near and discontiguous state.

Then, as shown in step 903-907 among Fig. 9, when predrive motor not shown in the figures being connected on the new axle 3 and driving revolution, and make new axle 3 with old axle 2 on band 30 in transmitting when rotating on equidirectional, programming controller 11 receive the detected portion 1h that detects cycle detection device 9 each pulse signal and to the maximum periphery of new axle 3, promptly the maximum outer peripheral face peripheral speed of the band 30 of new axle 3 is carried out computing, programming controller 11 control predrive rotating speed of motor make above-mentioned peripheral speed become the transfer rate of band 30 on the old axle 2 that transfer roller 38 rotating speeds are produced, when the transfer rate of the peripheral speed of the maximum periphery of new axle 3 and old 2 band 30 is consistent, the position that programming controller 11 detects the adhering part 6 of the axle 3 that makes new advances by the detection signal of cycle detection device 9 arrive at old axle 2 on transmit moment of position approaching between relative cutter 4 of band 30 in the action and the crimping roller 5, make the position synchronous of the adhering part 6 relative with this cutter 4, allow cutter 4 works cut off action for 1 time repeatedly band 30 cut-outs that transmit on the old axle 2, simultaneously crimping roller 5 is pressed to the below, also the cut-out end of the band 30 of transfer roller 38 sides is crimped on the adhesive portion device 6 of new axle 3 with old axle 2 disengagings, by adhering part 6 the uncoiling top of the cut-out end of band 30 on the transfer roller 38 with new axle 3 is serially connected, the band 30 thereby discharging makes new advances on the axle 3 is to replace from old axle 2 discharging bands 30.

So, being electrically connected of programming controller 11 conversion magnetic powder brake 1e, 1f and uncoiling side tension controller 47, provide Torque Control output from uncoiling side tension controller 47 to magnetic powder brake 1f, cut off Torque Control output simultaneously to magnetic powder brake 1e, and then being connected of the new axle 3 of releasing and predrive motor, stop to drive the predrive motor simultaneously, make crimping roller 5 risings and stop at its upper limit stop position, (referring to the step 908 of Fig. 9,909) finished in just accusing to the conversion of new axle 3 from old axle 2 of multiaxis device 1.

Changing under the completion status, new axle 3 becomes the old axle 2 shown in Fig. 8, the old axle 2 that is positioned at new axle 3 positions shown in Fig. 8 unloads from revoliving arm 1c, after the outer peripheral face pre-wound of abridged spool shaft other new axle of band in the installation diagram on the position of this revoliving arm 1c, programming controller 11 judgements are changed a time, just can carry out the axle that changes of multiaxis device 1 repeatedly and operate.

And in coiling portion, use the occasion of multiaxis device, its basic structure is the inboard Fig. 8 from paper, transfer roller 38, the direction of transfer of 39 rotation direction and band 30 is regarded the rightabout of its arrow as, and uncoiling side measuring roll 36, uncoiling side steering roll 35,37, uncoiling side tension detector 46 and uncoiling side tension controller 47 become coiling measuring roll 42, winding side guide roller 41,43, winding side tension detector 49 and winding side tension controller 50, and on the outer peripheral face of the spool shaft of blank coil winding reel 33, adhering part 6 is set, the outer peripheral face of the maximum outer peripheral face of reel spool 33, so just understood easily as spool shaft.

In transmitting, changes the band on old axle 2 30 in above-mentioned past the changing in the axis controller of multiaxis device 1 of axle, cut off the occasion of band 30 in cutter 4 actions, because its structure is by uncoiling side tension detector 46, the Tension Control feedback control system that uncoiling side tension controller 47 is constituted with magnetic powder brake 1e realizes, be lower than cutter 4 and cut off required tension force for example setting tension force, or in the feedback control system of Tension Control, introduced electrical Interference and the Torque Control output of uncoiling side tension controller 47 is reduced, perhaps the detection tension force of uncoiling side tension detector 46 uprises under the situations such as Torque Control output step-down that make from uncoiling side tension controller 47 when cutter 4 touches band 30, the braking moment of magnetic powder brake 1e is descended, strap tension between guide roller 1d and the transfer roller 38 is lower than cutter 4 and cuts off required tension force, like this, even cutter 4 actions, band 30 also can allow and edge a knife and can't cut band, thereby causes changing the axle failure.

The present invention addresses the above problem to propose, its objective is provides a kind of before the cut-out action beginning of changing a cutter in the feedback control system of releasing Tension Control, the braking moment of Torque Control actuator is fixed on cutter to be cut off on the required cut-out moment, thereby can cut off band with cutter exactly, realize reliably changing axle the multiaxis device change a control device.

A control device that changes that changes the multiaxis device of axle in band transmits of the present invention is provided with cut-out moment setting device and moment stationary installation, cutting off the moment setting device sets out with the required cut-out moment of cutter cut-out band, the moment stationary installation from old axially new axle change axle prepare cutter before cutting off the action beginning during, disengagement is exported with the Torque Control of actuator output the Torque Control of old axle, the cut-out moment that sets in this Torque Control of old output and the above-mentioned cut-out moment setting device is compared, Torque Control is exported and be conducted to the fixed end taken about the point of fixation control when changing as new axle with the bigger side of its value with in the actuator simultaneously.

Multiaxis device of the present invention change a control device, in the common transmission action of band on old axle or operation when beginning, cut off the moment setting device by operator's operating and setting, set out with cutter for cut-out moment setting device and cut off the required cut-out moment of band, old axle is gone up band and is still continued its transmission action, with the place-exchange of old axle with new axle, and the approaching old axle of the maximum outer peripheral face that makes the band of being reeled on the new axle is gone up the band in transmitting, after revoliving arm stops the rotation, drive new axle and on the identical direction of band direction of transfer, do pre-revolution, when the band peripheral speed of being reeled on the new axle during near the transfer rate of band, throw off from tension controller to the Torque Control output of Torque Control with the moment stationary installation with actuator, compare simultaneously with the cut-out moment of above-mentioned setting and with a side of higher value the fixed end taken about the point of fixation during as new axle conversion control and export and provide to the Torque Control actuator, when band is cut off in the cutter action, the band that separates with old axle is cut off end be connected on the adhering part of new axle.

Cutting off the operation of moment setting apparatus 12 by operating personnel preestablishes out and cuts off bands 30 required settings with cutter 4 and cut off moment.

Moment fixator 13, cut off in during before preparing to change axle to cut off the action beginning and export to magnetic powder brake 1e from uncoiling side tension controller 47 to cutter, the Torque Control output of 1f, compare simultaneously with from the setting cut-out moment of cutting off moment setting apparatus 12, with higher value person wherein when changing spool fixed end taken about the point of fixation control output and be conducted to magnetic powder brake 1e, 1f, specifically, moment fixator 13 forms in microcomputer, Torque Control output storage 14 is arranged, comparer 15 and switch 16, Torque Control output storage 14 constantly upgrade from Torque Control arithmetical unit 7 output of uncoiling side tension controller 47 the time be engraved in the Torque Control output valve of variation, comparer 15 is accepted from the cut-out moment output order of cut-out moment output order device 17 outputs of programming controller 11, reception from the up-to-date Torque Control output of Torque Control output storage 14 with from the cut-out moment of the setting of cutting off moment setting apparatus 12 and compared, with its higher value person when changing spool fixed end taken about the point of fixation control output and export.

Switch 16 is provided with the fixed contact 16a that is connected with the output terminal of Torque Control output arithmetical unit 7, the fixed contact 16b that is connected with the output terminal of comparer 15 reaches and magnetic powder brake 1e, the travelling contact 16c that the input end of 1f links to each other, the state that changes that travelling contact 16c before the axle beginning contacts with fixed contact 16a and the output terminal that Torque Control is exported arithmetical unit 7 is connected to the input end of magnetic powder brake 1e has been shown among Fig. 2, Fig. 1 then shows just cutting off travelling contact 16c before the band 30 and the output terminal of comparer 15 is received state on the input end of magnetic powder brake 1f, this travelling contact 16c is to carry out when switch 16 receives from the cut-out moment output order that cuts off 17 outputs of moment output order device from fixed contact 16a to the conversion of fixed contact 16b, travelling contact 16c from fixed contact 16b to the conversion of fixed contact 16a then be switch 16 receive programming controller 11 outputs preset new axis signal the time carry out.

Cut off moment output order device 17 and keep sending to comparer 15 and switch 16 synchronously of cutter 4 adhering parts 6 positions cut off the moment output order, and programming controller 11 presets new axis signal changing under the condition that axle finishes to send to comparer 15 and switch 16 by programming controller 11.

Below, the axle that changes that present embodiment is described with reference to Fig. 3-6 moves, as shown in Figure 2 band 30 from old axle 2 to the process that reel spool 33 (see figure 7)s transmit, at first shown in step 301-305 among Fig. 3 (step 901-901 is identical with it among Fig. 9), the signal that changes axle by the expression preparation rotates revoliving arm 1c, in case the band 30 between guide roller 1d and the uncoiling side measuring roll 36 becomes setting at interval to the interval of the band 30 maximum outer peripheral faces of new axle 3, revoliving arm 1c just stops, so just as illustrated in fig. 1 the maximum outer peripheral face of the band 30 of new axle 3 be configured in old axle 2 in transmitting band 30 near and don't contacted states, then by predrive motor not shown in the figures make new axle 3 with old axle 2 on band 30 in transmitting rotate on equidirectional, and the transfer rate of band 30 is consistent on the peripheral speed that makes the maximum outer peripheral face of band 30 on the new axle 3 and the old axle 2, and is all identical with the past example up to the operation of adhering part 6 that detects new 3.

Then, shown in step 402 among step 306 among Fig. 3 and Fig. 4, cut off moment output order device 17 and when the position synchronous that keeps cutter 4 adhering parts 6, send and cut off the moment output order to comparer 15 and switch.

Like this, the travelling contact 16c of switch 16 just from fixed contact 16c changing-over to fixed contact 16b, 15 pairs of up-to-date Torque Control outputs of comparer are simultaneously cut off moment with setting and are compared, and with a side of higher value when changing spool fixed end taken about the point of fixation control output and export, specifically, as shown in Figure 5, set when connect cutting off the moment output order and to cut off the up-to-date Torque Control of torque ratio and export when big, comparer 15 is exported to magnetic powder brake 1e set cutting off the fixed end taken about the point of fixation control output (output fix) of moment when changing spool by switch, otherwise, as shown in Figure 6, when the output of up-to-date Torque Control is bigger than the cut-out moment that sets when connecting cut-out moment output order, 15 of comparers are exported to magnetic powder brake 1e to the fixed end taken about the point of fixation control output (output fixing) of up-to-date Torque Control output when changing spool by switch 16, so just can save when changing spool exporting the pretty troublesome control measure of deliberately forcing down than using cutter 4 to cut off the bands 30 required also big Torque Control of settings cut-out moment.

So, still exporting to the control of magnetic powder brake 1e output fixed end taken about the point of fixation, make cutter 4 do back and forth to cut off action 1 time and the time the band cut-out in transmitting on the old axle 2, crimping roller 5 is crimped on the cut-out end of the band that separates with old axle 2 but link to each other with transfer roller 38 on the adhering part 6 of new axle 3 to pressing down also, thereby the cut-out end by 6 bands 30 that link to each other with transfer roller 38 of adhering part is serially connected with new axle 3 uncoiling tops, makes the discharging of the band 30 on the new axle 3 replace the discharging (seeing step 308 among Fig. 3,309) of the band 30 of old axle 2.

Then, shown in step 407 among Fig. 4, programming controller 11 switches to the travelling contact 16c of switch 16 on the fixed contact 16a from fixed contact 16b, thereby switched being electrically connected of magnetic powder brake 1e, 1f and uncoiling side tension controller 47, from uncoiling side tension controller 47 magnetic powder brake 1f is supplied with in Torque Control output, cut off Torque Control output simultaneously to magnetic powder brake 1e, remove again and being connected and making the predrive motor stop to drive of the new axle 3 of predrive motor, crimping roller 5 risings and be parked on its upper limit stop position.Just finished moving of multiaxis device 1 from the axle that changes of old axle 2 to new axle 3.

Change axle when being over, shown in step 408 among Fig. 4, programming controller 11 presets new axis signal to comparer 15 and switch 16 outputs, the travelling contact 16c of transfer switch 16 from fixed contact 16b changing-over to fixed contact 16a, magnetic powder brake 1f is passed in the Torque Control output of exporting arithmetical unit 7 from the Torque Control of uncoiling side tension controller 47, braking moment during magnetic powder brake 1f usual the running is applied on the new axle 3, just can suitably comply with the cut-out action of cutter 4 during Torque Control output when changing spool fixing, the result is owing to the driving of transfer roller 38, and band 30 just is sent to (referring to Fig. 7) on the reel spool 33 from new axle 3.

Be under the state changing axle, new axle 3 becomes the old axle 2 shown in Fig. 2, unload the old axle 2 shown in Fig. 1 and load onto the reeling other new axle of band of the spool shaft outer peripheral face that omits the figure in the position of its revoliving arm 1c from revoliving arm 1c, exchange axle times by programming controller 11 and judge, the axle that changes that carries out multiaxis device 1 repeatedly moves.

In a word, when cutting off band 30 with cutter in the present embodiment, owing to removed the Tension Control feedback control system, again the control moment of magnetic powder brake 1e, 1f is fixed on simultaneously and cuts off more than the required setting cut-out moment values, just can make band 30 not get out of the way and realize cutting off exactly from the blade of cutter 4.

And then, inboard Fig. 1 and Fig. 2 from paper, transfer roller 38, the direction of transfer of 39 rotation direction and band 30 is regarded as and the arrow reverse direction, uncoiling side measuring roll 36, uncoiling side steering roll 35,37, uncoiling side tension detector 46 and uncoiling side tension controller 47 are considered as winding side measuring roll 42, winding side guide roller 41,43, winding side tension force measuring roll 49 and winding side tension controller 50, simultaneously adhering part 6 is arranged on the outer peripheral face of spool shaft of blank coil winding reel 33 and the outer peripheral face of the maximum outer peripheral face of reel spool 33 as spool shaft, then will have routinely understood easily with the past the samely for situation about multiaxis device 1 being used in the coiling portion.

In addition, by in cutting off moment setting apparatus 12 corresponding to material based on band 30, the kind of fabric width and thickness etc. is different and preestablish with cutter 4 and cut off the required cut-out moment of band 30, to the cut-out moment output order and the instruction of specifying band 30 kinds of comparer 15 outputs from programming controller 11, comparer 15 will corresponding to the cut-out moment values of setting from the kind designated order of the above-mentioned band 30 that cuts off moment setting apparatus 12 read in and judgement and the output of up-to-date Torque Control between size, thereby the mistake that can prevent required cut-out moment values setting when cutting off bands 30 with cutter 4.

In addition, for coil diameter detecting device 10, though what illustrate in example and describe is the detection mode of cumulative thickness, utilizes the scale operation mode of not shown count pulse generator set on cycle detection device 9 and the transfer roller 38 and ultrasonic type, directly the armed lever of band roller be against on the material and also be same being suitable for the feeler lever formula structure of sensor measurement armed lever angles such as pot.

As explained above, the present invention transmits in the action at band, removed a Tension Control feedback control system of cutting off the action beginning when changing spool with cutter, simultaneously the braking moment of Torque Control actuator is fixed on cutter and cuts off on the numerical value more than the required setting moment and constitute, so just can eliminate the unfavoured state that band is avoided cutting edge roundness, thereby can cut off band exactly and change the effect that axle is received its quality of raising, reliability reliably with cutter.
