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.
