Detailed description of the invention

The basic function of vertical off line 1 these parts is always identical.Web 29 must be divided for subsequent process.In Fig. 1 and 2, show to simplified schematic the general principle of the vertical off line 1 of parts.

Web 29 be fed to cutter unit 3 from top by control framework 4 and be divided at least two, can be also multiple material bands 31 if desired, the material width of the band wherein cut apart can be different (asymmetric) or identical (symmetry).

Before cutting, web 29 is had the control framework 4 of roller 7 and is guided.Multiple rollers 7 along material throughput direction 28 be arranged parallel to each other and formation control framework 4 in the supporting base of arc.In manufacture process, before longitudinally cutting apart, correspondingly make thus web 29 static.

Web 29 is more accurately transported in vertical off line 1, just can more accurately measure and cut this web.Therefore be furnished with and enter guiding device 13 at the approaching side of vertical off line 1, this enters guiding device web 29 is carried out pre-control and therefore guaranteed correct center.Other less inexactness in material conveying before cutter unit 3 is compensated by control framework 4.Enter the adjusting of guiding device 13 can artificially or motor carry out.Use guiding finger or guide plate as the side direction equipment in web.

Driven cutter unit 3 is arranged in frame 2, and comprises at least two disc cutters that material is cut apart 5.This cutting process carries out under very fast device rate and otch must be realized continuously and accurately in web 29.Cut material bands 31 must meet the specific width tolerance in the margin of tolerance in +/-0.5mm.Cutter unit 3 can regulate transverse to material throughput direction 28.Therefore can regulate desired material bands width dimensions.On the both sides of disc cutter 5, be provided with the band Moving plate 6 of annular knurl, this is born and sends into the task of material and carry material with Moving plate.One of two cutter shaft 19 are driven.The joint of disc cutter 5 can be carried out by device for precisely regulating 18.

Disc cutter 5 thrust is each other adjustable.For this reason, not driven cutter shaft 19 with disc cutter together by means of regulon---normally cylinder 22---defeated to relative disc cutter 5 with adjustable.

Width adjusting device 14 these assemblies are positioned at whole cutter unit 3 on needed material cutting width by means of driver element.Cutter unit 3 is bearing on guidance system 16 transverse to material throughput direction 28 ground point-blank in frame 2 for this reason.Can cut out identical and different material bands width 31.If do not need cutter unit 3, this cutter unit by means of width adjusting device backward, towards the direction location at the machine back side.Can in the situation that not cutting, in equipment, carry thus web.

In frame 2, there are one or more guide rollers 12 in cutter unit 3 upstream arrangement.One or more tangent lines that web 29 forms between this guide roller 12 and last roller 15 of control framework 4.

Web via roller guiding has the trend of running out of from track.In the time of the different cutting angle of processing and material thickness, in carrying, material there is different situations especially.This for example causes, and the place that pressure no longer should occur at it occurs, and web can not accurately be extended by arris.In order to compensate this effect, the arris of web 29 is detected.Servo drive system 8 is revised orientation and web 29 is remained in the nominal position of regulation, even and if also guarantee that in the time that speed is higher position in process of production discharges accurately.

For web 29 being cut into the material bands width 31 of expectation, must correspondingly regulate again cutter unit 3 transverse to material throughput direction 28 in process of production for previous reasons.Lie in web 29 on control framework 4, that be transported to cutter unit 3 by correspondingly deflection or control.To this, web 29 contactlessly between last roller 15 of control framework 4 and the guide roller 12 of cutter unit 3 upstreams by camera chain 21 optical detections or detected by sensing element adjuster 20.Detection system 10 is transferred to the corresponding signal of servo drive system 8 one, a correction value, for making control framework swing or it is controlled, thereby makes web 29 also accurately extend past continuously cutter unit 3.Depending on width tolerance and the extension situation of carried web 29, control framework 4 must be controlled with positive-angle or negative angle and regulated value more or less.

For this reason, it is upper that the control framework 4 in top is bearing in a vertical centre of gyration---being vertical axes---, is connected in frame 2 with servo drive system 8, and can be conditioned in mode that can horizontal hunting around this centre of gyration.Servo drive system 8 is born the task of realizing described swing.The vertical centre of gyration is seen the middle position on approaching side 30 along material throughput direction 28.On the opposite side of servo drive system 8 in the centre of gyration.Control framework 4 is supported in frame 2.

In the embodiment to material throughput direction 28 side linear regulation, control framework 4 is bearing on guidance system 35 transverse to material throughput direction 28.Servo drive system 8 between control framework 4 and frame 2 is controlled for the control framework 4 of the web 29 to being placed on it.This principle is shown in Fig. 3 and 4.

In cutter unit 3 downstreams, divided material bands 31 travels through material separating device 17.This is to be bonded together and essential for fear of cut material bands 31.Material separating device 17 has been predetermined definite bearing of trend and has been prevented that material bands 31 from intersecting again for cut material bands 31.

For vertical off line 1, there is the embodiment of the vertical off line of hilted broadsword and the vertical off line of multitool.The vertical off line of hilted broadsword and the vertical off line of multitool are from the appearance almost as broad as long in principle.Therefore vertical hilted broadsword off line and the vertical off line of multitool are called parts " vertical off line " 1 by unification below.

Main difference is the right quantity of cutter in cutter unit 3, and this quantity must reach the quantity of the material bands 31 that will cut out in equipment output.
