Description
Technical field
Theme of the present invention is the device that metal tape is detected in output place of online treatment equipment.
Background technology
In the online treatment equipment of metal tape, especially in rolling equipment, metal tape must be at the output place wound into coiled stock of handling section so that easily be transported to another part of this equipment or another field of employment fully.
For this reason; We use wrapping machine, and this wrapping machine comprises axle, this axle on frame, be mounted to round with the axis rotation of the feeding longitudinal axis quadrature of metal tape; And on this axle, be applied with turning moment; The metal tape thereby the tractive force that allows use in the operation of rolling, to need is reeled in addition, also makes it possible to let be applied on another circle around circle one circle.
For a long period, in order to improve production capacity, this equipment continuous operation, the afterbody of the roll coil of strip and the head of the next roll coil of strip welded together when unwinding finished.
In order to keep the continuity of metal tape feeding in the treatment facility, the winding mandrels of two alternations is installed usually in output place of treatment facility.
Traditional method is, uses two wrapping machines, they one then a ground be placed in the hole that is provided with in the pedestal, in the feeding under of metal tape.
What for example, document WO 2006/051239 was described is exactly this device.
Yet; To change the necessary time of the roll coil of strip and reduce the expense of infrastructure and equipment simultaneously in order to reduce; The wrapping machine that use is called " circulating conveyor formula (carrousel) " is favourable, and it comprises two winding mandrels that are installed on drum barrel (tambour) the shape frame, and said frame is rotated round the axis with the direction of feed quadrature; So that one after the other each axle is placed into the primary importance of the beginning of reeling; Through rotary frame, be placed into the second place of reeling and finishing then, take turns to another axle then and come primary importance.Like this; After the roll coil of strip that is positioned at the axle coiling on the second place has reached the maximum gauge of wanting; It is disconnected that metal tape just is positioned at the shearing of handling section output place; So that the roll coil of strip that allows to be rolled up is withdrawn from, the head of the metal tape of handling simultaneously can be drawn towards another axle that has been in the primary importance of the beginning of reeling immediately.
In addition, in the operation of rolling of metal tape (for example sheet material), the defective of flatness may appear.Equally, may produce vestige, and vestige can repeat periodically in rolling process to occur in the one side of the metal tape that for example contacts or another side with roll, therefore metal coil tape around after can be present in the whole roll coil of strip.
Therefore,, be necessary the sheet material that regularly detects from milling train, to come out, at least on pairing that segment length of that a period of time that repeats to occur with vestige in order to detect the geometrical defect or the product surface quality defective that might take place.For obvious defects, we can do simple detection through vision.Yet in fact, preferably, use the method that is called " honing ", this method is intended to special building stones are passed through so that defective manifests from the sheet material that is placed on the horizontal table top.
In order to realize this detection, can extract the roll coil of strip in equipment output place every now and then, then it is placed on the unwinder to get off so that will detect the metal tape unwinding of Len req.
This device is heavy and expensive, and this device is merely able to detect the single face of metal tape.
Someone is the on-line measuring device of suggestion use once also; These on-line measuring devices can be checked sheet material certain-length, that form sample that extracts from metal tape; Said sample is placed on the monitor station, can this sample be turned to detect another side then.
For example, document JP-A-2000-254 725 has described this type of device.This device comprises circulating conveyor formula wrapping machine and monitor station in output place of rolling equipment; This monitor station supporting is several to centering on the pinch roll of side shaft line Rotate 180 degree simultaneously; Be arranged on cutting of last milling train seat downstream and can cut off the sample that is maintained between the different pair rollers, then through pinch roll Rotate 180 degree being made the sample upset to detect lower surface so that detect upper surface earlier.
Document WO 2006/051239 has been described another kind of device, and this device can be avoided relying on table top as support.In fact, in this case, sample is stretched between two binding clips, and these two binding clips are mounted respectively on two rotating disks that vertically separate, and can rotate simultaneously with the upset sample round longitudinal axis.
In this layout, as stated, use two wrapping machines that are arranged in succession in the hole.Therefore, each wrapping machine must be equipped with envelope device (enveloppeur) with instant rolled around beginning, switch (aiguillage) also is housed simultaneously, or is used for, or be used for head guiding axle with metal tape the sample checkout gear that leads.
On the contrary, the circulating conveyor formula wrapping machine of describing among document JP-A-2000-254725 can only use a switch and an envelope device to serve two axles of coming winding start position in succession.
Yet the head of jointing metal band must accurately be guided the metal tape head into axle through being arranged on the switching device shifter of cutting trip for ease.Therefore, must apply certain bending force metal tape is guided into the axle that is positioned at the feeding under to metal tape.For this reason, metal tape is passed through between two transversely movable rollers, perhaps can push back to axle through the push roller (rouleau-pousseur) that activates by jack head with metal tape.Also can use guiding device, like the knowledge of many institutes, this guiding device comprises two hang plates (plateau), they are arranged on the metal tape both sides and form the guiding groove that entad axis congruence gathers.
In addition, with after the engagement of metal tape is on axle, make the head of metal tape several circles of reeling, thereby the rotation of controlling frame then causes its winding position with axle, and it is replaced with another axle that is positioned at winding start position.
In the second place of this fully relative (diam é tralement oppos é e), metal tape must bear relatively large tractive force, and this tractive force points to the deflection roll that is arranged on inherent wrapping machine top, feeding plane.
Yet; We observe; This tractive force of points upwards is tending towards through to alignment bearing (palier de centrage) with to being used for support frame being fixed on that device on the pedestal applies power and the rotation drum barrel that will carry axle upgrades; Like this, in the course of time, will produce injurious effects to the performance of material and the quality of coiling.

The specific embodiment
In the drawings, schematically show and be arranged on output place of sheet metal online treatment equipment, at the checkout gear of handling section A (not shown) downstream, said online treatment equipment for example comprises the cold-rolling equipment of the support of continuous several tandem workings.
For example, among the embodiment as shown in the figure, the output section 1 of equipment can comprise along the direction of feed of metal tape M (promptly in the drawings from right to left direction) in succession: deflection roll 11 is used for guiding metal tape M into edge scissor (cisaille de rive) 12; The metal tape drive unit, for example, a pair of pinch roll 13 that is installed on the frame 12 and is driven in rotation; The flying shear 14 of known type, it can shear the metal tape in the feeding; And wrapping machine 2, be used for metal tape at rolling or other processing back wound into coiled stock.
As stated; Advantageously; This wrapping machine 2 is to comprise two complete relative axles 21,21 ' circulating conveyor formula wrapping machine by rack support; Said frame does not illustrate in the drawings, and it becomes the drum barrel shape, on support frame 22, is mounted to center on horizontal axis 20 (with the direction of feed quadrature of metal tape M) rotation.Each axle 21,21 ' is equipped with the device that is used to engage and clamp the metal tape head that does not illustrate in the drawings in known manner.Each axle 21,21 ' also can be driven around its axis 23,23 ' rotation by driving torque, and said driving torque can apply on the one hand metal tape and be the rolling required tractive force T around circle that guarantees that the metal tape wrapping becomes to join of being enough on the other hand.
In addition; As everyone knows, wrapping machine 2 is equipped with unique envelope device 25 to realize the coiling of initial a few circle on axle, and envelope device 25 comprises at least two lead arm 26,26 '; The degree of crook of their decision metal tapes; Said envelope device is installed on the frame, moves between bonding station that this frame can illustrate in the drawings and the position that separates, wherein on said bonding station; Said lead arm 24,24 ' is around axle 21, and the said position that separates makes that frame can be round its axis 20 rotations.
When rolling pass began, the engagement of clamped roller driving of metal tape M (representing with chain-dotted line) and metal tape was on first axle at the primary importance E1 place that is positioned at the beginning of reeling.The engagement of metal tape on axle and after several circles of having reeled, is made the frame rotation so that first axle is brought to relative second place E2 fully, and second axle moves to primary importance E1 place then.The second place E2 place that is wound on of metal tape proceeds, up to obtaining the roll coil of strip 3 with diameter d.
As stated, in whole winding process, metal tape receives tangential force T always.
On axle 21 ', reeled after the metal tape corresponding to the desired length of the maximum diameter d of the roll coil of strip 3, metal tape M is cut 14 and is cut off, thereby can the roll coil of strip 3 be unloaded on the handling carrier 24 so that it is withdrawn.Articulated jib 31 can maintain the metal tape of this winding before the metal tape of winding is taken over by handling carrier 24.
Yet after shearing, the head of new metal tape just has been directed to the axle 21 of the primary importance that is positioned at the beginning of reeling immediately.As stated; In the conventional equipment of in JP-A-2000 254725 for example, describing; Circulating conveyor formula wrapping machine is positioned in the hole, in metal tape feeding under, therefore is necessary the head of metal tape is applied bending force so that accurately guide it axle of wrapping machine into.
But in layout of the present invention (illustrating in the drawings), the axle 21 that is positioned at winding start position is located substantially in the downstream of cutting 14 on the height of feeding horizontal plane P of metal tape, and the rotation 20 of the rotary frame of wrapping machine is positioned at this top, plane.
Therefore, need not in the pedestal that is fixed with the distinct device instrument, bore the hole again to settle wrapping machine 2.
And major advantage of the present invention is; After shearing, the head of the new metal tape that is driven by pinch roll 13 is located substantially on the axle 21 on the height on feeding plane by guiding naturally; Therefore, the head of new metal tape can easily join in the jaw device that is provided with on the axle 21.Therefore; In order metal tape to be guided into axle 21; Only need and cut the guided plate 4 that basic horizontal is set between 14 in axle 21, this guided plate for example can be made up of belt conveyor, and said belt conveyor comprises and is stretched in two rollers 42, the continuous belts between 42 ' (bande sans fin) 41.
In addition, because the rotation 20 of rotary frame is positioned at the top of axle 21, second axle 21 ' that therefore is positioned at second place E2 place relative fully, that reel end is positioned at higher relatively place, feeding plane P top.So; During rotary frame is to make axle move to the rotation that position E2 carries out and up to the roll coil of strip 3, reel and finish; Metal tape is all following the path that becomes certain angle of inclination (α) with respect to the feeding plane P, and the tractive force T that is applied on the metal tape is downward always.In conventional arrangements, tractive force is tending towards wrapping machine is upgraded, and in the present invention, is on the contrary, be applied on the metal tape and tend to framework 22 with wrapping machine by being pressed on the pedestal 15 via the tractive force of axle transmission.
The result that this layout of wrapping machine causes is, the monitor station 5 that should place metal tape sample to be detected on it (nettement) significantly is positioned in the top of feeding plane P, rather than as in the past basically on the height on this plane.Therefore, for the metal tape sample is transported to monitor station 16 places from cutting 14 always,, use the transmitting device 6 that above the roll coil of strip 3, passes through according to the present invention.
In preferred embodiment as shown in the figure; Said transmitting device 6 comprises guide table 61; Guide table 61 forms and is inclined upwardly so that be stretched in two continuous conveyors 62 between the roller that separates at plate that passes through above the roll coil of strip 3 and supporting when finishing reeling, said two rollers that separate be respectively be positioned at metal tape feeding plane P slightly the place, top position upstream rollers 63 be positioned at the perpendicular Q downstream rollers 63 ' in downstream slightly.The axis of the axle 21 ' of said perpendicular Q through being positioned at coiling end position E2.
Preferably, continuous conveyor 62 is magnetic type, and it comprises the series of magnets 64 between the two parts that assign into continuous conveyor 62, and this continuous conveyor is arranged on the lower surface that turns to feeding plane P and wrapping machine 2 of guide table 61.
In addition, in order guide table 6 to be remained on the minimum distance above the metal tape in winding process, plate 6, is supported on the outer surface 32 of the roll coil of strip 3 through roller 65 round hinged with the axis 60 of direction of feed quadrature in its lower end in the top.Preferably, this roller is covered with the material that can not damage the surfaces of metallic strip quality, and this traditionally material is used for various deflection roll as the metal tape guiding piece.
In addition, in order to reduce the power that is imposed on the roll coil of strip by roller 65, the weight that is supported with the guided plate 6 of conveyer belt is compensated for by the jack hinged at equipment skeleton C place 67.
On the other hand, at the upstream extremity of metal tape direction of feed, guide table 6 is provided with that be mounted to can be round the deflection roll 66 of the hinge axes of plate 61 60 rotations.
According to another kind of preferred arrangements, cut 14 and axle 21 between metal tape guiding device 4 be used to the metal tape sample is applied on the magnetic conveyer belt 62,64 so that with its guiding monitor station 5.
For this reason; Continuous conveyor 41 is installed in hinged and can be through on the directed tabular frame of jack 43 round axis 40; The body supports of said jack is on pedestal 15, and the bar of said jack then is hinged on the supporting device that connects with orientable plate 4 round axis 44.
In order to realize the detection of metal tape, on metal tape, implement corresponding to other shearing in twice minute of expecting to detect length through cutting 14.
After shearing for the first time, the afterbody of previous metal tape is wound onto on the roll coil of strip 3 that can withdraw.Then, jack 43 upwards pivots guided plate 4, is positioned at centre position shown in Figure 2, so that when shearing from the first time of sample, the head of sample just is drawn towards can be with the magnetic conveyer belt 62 of rear tube sample.Plate 4 continue to pivot up to conveyer belt 62 straight positions (being the position of representing among Fig. 3), cut 14 and implement to shear for the second time with sample M1 separately.The clamped roller of sample M1 13 promote and be applied on the magnetic conveyer belt 62 in case by the magnetic conveyer belt drive from the roll coil of strip 3 tops through and towards monitor station 5.
Because magnetic conveyer belt 62 is positioned on the lower surface of plate 61, the sample that therefore leaves conveyer belt 62 can be placed on the monitor station 5 easily.Usually; Monitor station is made up of continuous conveyor; Preferably, the upstream extremity 51 of this continuous conveyor was opened with wrapping machine and is connected with the downstream 63 ' of guide table 6 through transport platform 7 in 2 minutes, and this transport platform 7 also comprises continuous conveyor 71; It is installed on the tabular frame (not shown) and is stretched between two rollers that separate, and these two rollers that separate are respectively upstream rollers 72 and the downstream rollers 72 ' that is positioned at upstream rollers 51 next doors of monitor station 5 that is positioned at the downstream rollers 63 ' below of guide table 6.
Like this; Dispensing begins to break away from magnetic conveyer belt 62 from downstream rollers 63 ' on magnetic conveyer belt 62 lower surfaces and by the sample M1 that it transports; And fall to putting on the top of continuous conveyor 71 of transport platform 7; Take turns to transport platform 7 then sample M1 carried downstream is located up to monitor station 5 (only showing its upstream portion), this monitor station 5 is made up of continuous conveyor too, and its length of known ground is corresponding with the desired length of sample.
As stated, guide table 6 directly is supported on the roll coil of strip 3 so that follow roll coil of strip diameter variation through roller 65.Yet the length of the metal tape of reeling on the roll coil of strip, thereby the maximum gauge of this roll coil of strip can change, because in the continuous rolling process, can handle the sheet material with heterogeneity and different size continuously.For example, what Fig. 1 and Fig. 2 showed is the roll coil of strip 3 of maximum gauge, and the layout that Fig. 3 shows is then corresponding to the roll coil of strip 3 of minor diameter.
Therefore, transport platform 7 also must be followed diameter variation.
For this reason, transport platform 7 is hinged corresponding to the horizontal axis of the rotation of downstream rollers 72 ' round preferably in its downstream, and said downstream rollers 72 ' is positioned near the upstream rollers 51 of monitor station 5.Transport platform 7 can be through jack 73 orientations, the intermediate altitude place between the roll coil of strip 3 that makes its upstream extremity 74 be positioned at all the time to reel when finishing and the downstream (downstream rollers 63 ' of magnetic conveyer belt 62) of guide table 6.
Shown in figure, the upstream extremity of transport platform 7 can be provided with gradually thin part 73, and the guiding beak that extend the below that gradually thin part 73 is formed on the lower part of guide table 6 is so that sample is sent to transport platform 7.
Have benefited from these layouts, at the coiling initial stage, the head of metal tape is directly guided into axle 21 and is remained on simultaneously in its feeding plane P.According to the present invention; Because the rotation 23 of axle 21 is located substantially in the plane P, one of them arm 25 of envelope device extends above axle 21, with its common guide space that forms; This guide space tightens up gradually, and the head of metal tape joins in this guide space naturally.
After former circles had been reeled, the frame of wrapping machine was rotatable so that take axle to its position E2, and jack 67 can carry out said rotation with the roll coil of strip that guide table 6 gets out to allow reeling simultaneously.When the roll coil of strip was positioned at position E2, guide table 7 was lowered up to roller 65 and touches the outer surface around circle.As stated, in winding process, metal tape is from deflection roll 66 angle (a) that begins to be inclined upwardly, tractive force T directed downwards.
When the metal tape of expectation length had been wound into the roll coil of strip, metal tape was sheared so that produce the head of sample M1, guided the head of sample M1 into guide table 6 through rotation cut bank 4.It should be noted that advantageously the hinge axes 40 of cut bank is positioned at its middle body and downward skew as shown in the figure.Like this; The continuous conveyor that constitutes cut bank 4 rotates round its point of contact with deflection roll 66; And upstream rollers 42 is left downwards so that let the head of sample M1 pass through, and the head of this sample M1 moves upward with mode as shown in Figure 3 through the downstream 42 ' of switching conveyer belt 4 and is applied on the lower surface of continuous conveyor 61.
Therefore, sample M1 is guided until monitor station 5 places by cut bank 4, guide table 6 and transport platform 7 in succession, above wrapping machine 2, passes through simultaneously.
The raising of wrapping machine 2 positions makes can cancel the hole that is generally used for placing wrapping machine 2, thereby can all devices all be arranged on the same grade slab 15.In addition, the roll coil of strip 3 ' of winding is withdrawn from also very convenient.
Equally, monitor station 5 is raised to higher relatively height place, grade slab 15 tops, convenient laying of switching mechanism (for example as the switching mechanism of describing among above cited document WO 2006/051239 or the JP 2,000 254725).
But obviously, the present invention is not limited to the details of the above-mentioned preferred embodiment of describing as an example.
Especially, sample is passed through on a series of continuous conveyors 4,6,7,5, but also can use other conveyer.
Equally, though described the common circulating conveyor formula wrapping machine that comprises two complete relative axles, also can use the wrapping machine that for example has 3 axles.
