Description

Have fixed hook, be used for metal rolled or the line that draws and/or the coiler of bar

Technical field

The objective of the invention is a kind of feature, that have fixed hook, coiler of being used for metallic rolled or draw line and/or bar according to main claim.

The Wiring apparatus and/or the material production line that comprise described coiler also are parts of the present invention.

Definition

Line and/or bar are all understood with the strictest meaning, the meaning of bar promptly has than major diameter and/or has the profile of changes shape and/or the material in cross section, it will be wound in coil by live spindle or the spool that flange is arranged, and described coil takes out and send to the binding machine again.

Described line and/or bar and/or profile and/or cross section can be made in continuous or discontinuous mode with various speed in rolling and drawing device, and preferably (although not exclusive) makes in the Continuous Heat rolling equipment.

In this manual, the definition of the material material that maybe will twine is the above-mentioned elongated material of any type.

Background technology

In the current state of this area, known dissimilar line coiler particularly derives from the coiler of the continuous manufacturing apparatus of rolling and draw line or bar.

Particularly, in the rolling field, need very high process velocity, therefore line or bar are segmented into and the corresponding definite length of coil, redirect then, so that on one or another coiler unit, twine, like this, so that when forming coil, another coiler draws off the coil of having finished when a coiler wrap wire.

A subject matter during high speed is that line is introduced coiler (being also referred to as wrapping machine or axle re-reeler), and this carries out in the time of must onlinely advancing, and can not stop to advance of described line.

There is multiple different system to be used to introduce and extract the end of the material that will twine at present, so that under the situation of tension a little, described material is wrapped on the axle of coiler, like this, owing to slight tension material in winding process, therefore make the compact and good coil that is shaped.。

The first lap by can forming coil at least or the guide channel of a series of first laps are carried out the introducing and the clamping of line.

US3592399 (on July 13rd, 1971), FR2057722, GB1277515, DE2027516 (MORGAN) have introduced a kind of line wrapping machine, wherein, coiler enters conduit, and form first lap by half guiding piece that use has 180 ° of circular arcs and (see specification sheets, Fig. 3,4,5,6,7 particularly), this half guiding piece can make the line introduced or bar along the shape of axle, so that it self closely and apace is wrapped on the described axle.

1976 disclosed US3945585 on March 23, (DEMAG) a kind of conduit is provided, be used for accurately forming entering and the clamping conduit of line by the bell-shaped element (10,6,11) that moves forward and backward, thereby clamping and formation are around the first lap of the coil of axle in the process of twining first lap.

US-4664329 (Pali-Essex-1987 May 12) provides a kind of line guiding and grasping system, be used for bringing the formation coil by bar, this band winding around spurs it simultaneously, thereby makes the winding mandrel rotation, force the compact winding of line self like this, continuously.

DE821666 (Siemens-1949 July 8) has introduced the guide channel that is used for line/bar and the different system of clamping, so that be used for forming the coil around axle/coiler spool.Particularly, see specification sheets and accompanying

drawing

1,2,3,4,5,6,7, they have been represented to be used to guide and have hooked or the different schemes of the end of clamping line 3.

EP1126934 and EP1126935 (Danieli) have also introduced the line designating system that is used to begin to form coil, are similar to Morgan.

Disclosures in Italian patent application UD2004A000006, UD2004A000007 (Danieli) relate to and two schemes that aforementioned schemes is identical to a certain extent, wherein, fixedly conduit of described line/bar is provided, and uses the dynamic operation clamp to come the end of clamping material, so that form first lap.

In the scheme of DEMAG and in the scheme of DANIELI, the dynamic clamp system provides wired clamp function, and line released (returning in the DEMAG system) then is so that twining when finishing and can take out coil from winding mandrel.

In a kind of known Danieli scheme, work similarly among the grasping system of the first lap of line and the US3945585 (DEMAG), but whole base flange motion, this base flange is moved along axle, it is darker to make that line enters conduit, so that can embed some circles, is return then, when forming returning of the second layer and twine, only cover the part of first lap.The structure of this scheme is very complicated, and makes the required kinematic mechanism of big quality (for example base flange) also very expensive.

In other scheme, provide measure so that line follows simply, like this, more multi-turn self has been determined clamping.

A feature that repeats in existing scheme is to enter guiding piece, is used for as described above by the form of semicircle circular arc guiding piece line being slided, because friction force, this guiding piece will make the head-bent of advancing line, and self is wrapped on the axle.

Have fixing circular arc conduit and do not have the designating system of rotating element that the shortcoming of the bigger friction of generation is arranged, and because the line that will twine still hotter (when it during from hot rolling), it will be very soft, therefore may cause entanglement, force Wiring apparatus to stop, and therefore whole production line is stopped.

And, (this guide channel has 180 ° of semicircular in shape in the scheme of Morgan to use this guide channel, and in the scheme of Danieli, cover 360 ° whole circle axle by two relative semicircles) produce tangible temperature accumulation problem (because this guiding piece hinders heat radiation), and because material must slide and produces wearing and tearing against these guiding pieces.

It can't guarantee reliably to hook or clamp the line that the shortcoming of the material that will twine may cause introducing and break off relations, thereby may cause entanglement, and needs breaks in production under serious situation.

In fact, should be known in that the axle of coiler must be with the circumferential velocity rotation higher a little than the speed of advance of material, like this, material is arranged under the situation of tension a little, so that correct and winding compactly.

But, this makes material break off relations when just introducing usually, so overslaugh production.

Summary of the invention

Main purpose of the present invention provides a kind of more effective and suitable system, so that do not guide automatically under the situation of dynamic pincer system and hook the material that will twine having, and will be restricted to minimum to the damage of line during online introducing.

This problem solves by the feature of main claim.

Subclaim requires to have represented the preferred embodiments of the present invention.

Like this, have the relative pressure guiding piece of roller by use, apparent friction reduces, therefore can quick heat radiating, and the end of the line that can more effectively will introduce is pressed in the maintenance system of first lap or its part, thus avoid line self wearing and tearing and damage.

And, owing to use the tooth rim of the bottom of the flange that is arranged in winding mandrel, this tooth rim is left axle self a little according to wanting the diameter of section of winding material, this tooth rim and relative guides fitting effect (described roller pushes the material that enters between the tooth) with relative claw type roller, and the accurate effect of the similar pawl of axle and the described material of clamping, therefore can perfect, reliably and apace hook material, therefore and the danger of not unclamping guarantees unhinderedly, perfect and form coil apace.

In fact, clamp jaw is substantially by forming with the lower part:

The bottom tooth rim, this tooth rim is rotated with axle, and the helical rib at the relative position of axle side is preferably arranged;

Half wheel rim of upper roll, they are static, that is to say that they do not rotate with respect to axle, but idle running, therefore with the top tooth same way as operation of pawl, but static and rotation, so they force the material self that advances to insert between the outside face of bottom tooth rim and axle.

Therefore, having the hook system of pawl (this pawl has the clamping tooth) and the thought of formation first lap is used for especially effectively:

Tooth, and not as existing scheme in conduit, but at a side (downside); And

Idle press rollers at opposite side (relative upside);

On the surface of axle, also there are helical rib or the tooth relative with tooth.

The present invention also proposes to use removable tooth, thereby make coiler adapt to dissimilar lines or bar or cross section and differently contoured at an easy rate, otherwise also will need to change wrapping machine, because identical conduit can not be applicable to the winding material of wanting of Any shape or profile.

As an example, flat rolled cross section or moulding cross section or even level and smooth or the bar (diameter with variation) etc. of rib is arranged, the various winding material (for example be directed to a rolling equipment or derive from a plurality of rolling lines that separate) of wanting all will become clear.

Therefore, advantageously make coiler can twine kinds of materials, this is also relevant with the intermediate transport device, normally at the binding machine in downstream, is used for bundling this coil when finishing coil.

Description of drawings

To understand the present invention better by means of accompanying drawing below, accompanying drawing comprises particularly preferred (but not being a restrictive) embodiment.

In the accompanying drawing:

Fig. 5 has represented the identical view of Fig. 4, and combine with Fig. 6, Fig. 6 has represented the enlarged drawing of the shape and the structure of tooth, and represented how line or bar or bar (material that will twine) closely cooperate between tooth and axle body, at this in particular cases, the material that twines (T1) is the shape that the bar of rib is arranged, and this material is mainly used in the enhancing concrete structure in the building.

At this moment, clear seeing that the rib of bar (T1) is easy to insert between the tooth (252), thereby block this in complete failure-free mode, but, also is like this when not having described rib.Fig. 6 has represented that this clamping rib obviously improves clamping action, and anti-principal vertical line is owing to the spiral fluted internal traction is escaped at scheme drawing axle, that face toward the lip-deep helical grip rib (2531) of tooth (252).Fig. 7 has represented the view that amplifies more of the left part of Fig. 3, so that illustrate in greater detail the have roller pressing system of (234,2341), this roller promotes bar gradually and bar is remained between described clamping tooth (252) and the axle (253).

Similarly, Fig. 8 has represented the amplification right side view of Fig. 3, so that the recessed bowed shape (2520) of tooth (252) towards axle not only is shown, its inclination trapezoidal shape towards outside (2521) also is shown, so that tilt with prevent that its height from surpassing the diameter of bar (T1), thereby avoid the circle between overslaugh formation insertion one circle and another circle, promptly between first row and the 3rd of coil arranges.

Like this, should be known in that coil can take out at an easy rate vertically when finishing, and can not influence its shape, size or weight substantially by the minimum space that tooth (252) stays.

The specific embodiment

As seen from the figure, twine the unit and comprise: coiler (2), this coiler (2) is connected with the engine installation (M, M1) of the axle that is used to make it (25) rotation; And semicircle pressure apparatus, this pressure apparatus becomes the form of opening pawl (233), this opening pawl has the pressure roller (234,2341) on arm (232), this arm (232) hinged (230) and return lever (231) driving by having piston (23), this piston (23) is hinged on the pedestal (20) of coiler (2).

Like this, shown in fine rule, it comprises the have roller pawl of (232,233), this pawl is towards outside opening, can raise and reduce, so that be pressed on the bottom base flange (252) of winding mandrel (253), according to the present invention, therefore this base flange has tooth rim, is used to keep material (252) and against these teeth.

The tapered inlet of the approaching side (235) of pawl (233) helps entering of line, and and then this import has first pressure roller (234), and it is more effective that this enters scheme than other.

Pressure claw (232 ..., 32) hinged for like this, be that it can move in the outside position of opening between basic of material winding zone (when finishing with convenient coil when line and can't help to allow when actuating device keeps tension to be applicable to that other serial opposed roller (not shown) of maintenance last lap coil is approaching against the engage position of tooth rim (252) from its roller (234,2340,2341), this makes it possible to catch and take out coil, and their each circles itself are relaxed).

Winding mandrel (253) have roller by being arranged in (233,234) the pawl side the downstream motor system (M, M1) effect and with the rotation of variable speed.Like this, winding system is without any obstruction, thereby can engage so that make after safeguarding unwinding that other quadrature opposed roller is relatively approaching in the last winding stage.

Revolution speed calculating promptly always has and the corresponding identical outer circular velocity of the linear travel speed of line for like this, and assembly is controlled by the electronic control unit away from safety system, so as can not to be twined or wrapping range in the Temperature Influence that forms.

Axle comprises can return fan-shaped part, and when coil was finished, this fan-shaped part was return ordinatedly with downward and inside motion (255,256), and this scallop branch is arranged to taper, so that the coil that the taking-up that makes progress forms and the end of a thread that discharges first front clamp.

Transverse groove (2510) is arranged on the base flange (251), so that make and can utilize relative gripper jaws to firmly grasp coil, thereby take out coil by raising, described flange is integrated in the structure of axle self (2530), therefore simplify the structure, do not have complicated kinematic mechanism.

In detail, axle (2530) is formed by described (although not shown) on flange (251) pedestal four hinged fan-shaped parts, these fan-shaped part tensions are so that take out, and also be connected (by the below running gear (257) of axle (255) and unit (256) with mechanism, the rotating mechanism (not shown) of corresponding four fan-shaped parts of upper flange (254) links to each other, and the petal as flower raises, thereby makes it possible to upwards take out coil (petals close)).

At the wired guide roller in the front side of coiler (2) (1), this line guide roller (1) comprises the horizontal guide (121) of pedestal (10), this horizontal guide (121) is vertical with the preceding inlet wire (X-X) of the medium of material, and sliding part (11) utilizes borded pile (111) to be installed on this horizontal guide (121).

Therefore, sliding part (11) is according to instruction (not shown) and alternating movement, so that borded pile (11-111) is moved according to axis (Y-Y), thereby make it always remain on the route, promptly tangent with the coil cooling diameter of axle (253), along with the diameter increase of coil in twining, this cooling diameter increases gradually.

Therefore borded pile (11-111) makes sliding part (110) with crank motion mode (alternately) perpendicular movement, like this, this sliding part (110) raises according to quadrature-axis (Z-Z) and reduces, so as to form gradually winding around forward with return circle.

Therefore, (this borded pile passes through the known electric motor of for example stepping control and passes through the appropriate electronic control unit and left rotation and right rotation by borded pile (111), this electronic control unit is checked all motions of wind) and end that the plate of the sliding part (110) of perpendicular movement supporting member or waved guide bar (1131) by hinged support, this supporting member or wave guide bar (1131) carrying and want winding material is for example from line or the bar or the bar of the mill with suitable diced system (not shown).

Described guiding piece hinged (1130) so that can reciprocal inclination, be used for forming circle at coiler (25) on described plate (110).

Guide bar supporting member (11341) comprises the guide channel (113) of material, the wired guiding import of this guide channel extendible portion (1130).

Be right after this guide channel (1130-113) downstream and wave line guiding extension part (112), this waves line guiding extension part and waves on pin (1120), so as always to make winding material keep once making progress (its center line guiding extension partly moves downward) according to the angle of inclination and once downward (wherein, line guiding extension part upward movement), like this, the angle of inclination is always corresponding to the winding angle of inclination of the line that twines on bobbin, this angle and out of plumb.This end of waving line guiding extension part (112) is preferably replaceable, so that adapt to the shape type of the material that will twine.

Therefore, the material that advances leaves line guiding extension part (112), and introducing has the import (235) of the pawl of guide reel (233-234), wherein, material (T1) is pressed between the outside face of tooth rim (252) and axle (253) gradually by roller (234,2341), thereby with forced mode clamping material (T1).

Like this, material (T1) is blocked in the tooth rim (252), and helps elastic threads, so that closely be wrapped on the axle (25).

Should know, preferably first enter roller recessed (234-2340) a little, so that help material (T1) to enter, then, subsequent roller is cylindricality (2341), so that material (T1) is pressed in definitely between the outside face of tooth rim (252) and axle (253), up to the bottom that knocks base flange (251).

Certainly, also can or the roller of rib be arranged, promote line or bar between tooth better so that in the end leave the stage (end pawl) in the overhang bracket convex.

Inner recessed arc tooth (2520) helps to hook material, and helps to put to stop material to be escaped from.

The external trapezoidal shape of tooth (2520,252) makes it possible to put better each circle subsequently of coil, is not staggered to form and can not hinder them.

Should know, idle press rollers is installed (233) on bearing (2331-2332), and this bearing is with the axle (2342) of the mode bearing roller 234 that dangles, therefore, described roller 234 has enlarging inclined flange (2342), and this flange (2342) cooperates with the inclination step surface (2521) of tooth (252).

This improved supporting member helps to control in accurate mode wants passing of winding material.And the roller that dangles towards axle can make it farthest near having the axle of improving the line guiding piece.

Certainly, as previously mentioned, all teeth (252) can change other suitable shape into, so that adapt to the winding material of wanting of difformity and size.

The number of pressure roller (234) obviously can alter a great deal.

In order to keep better, can also be provided for catching the protrusion helical rib of material, it is arranged on the outside face (2531), and is corresponding with axle (253) part facing to tooth (252).

In case formation coil, axle diameter are return and become to present cone shape, therefore discharge first and twine the clamping strip of circle, thereby help upwards to take out coil.

Preferably, the inside face of described tooth (252) has rib and/or tooth is arranged and/or protruding joint is arranged.Like this, going up assurance apparent surface (2520) catches better.

The convertibility of described tooth is guaranteed by the fixed system that passes described base flange (251).Like this, when odontotripsis, can change at an easy rate, even change them so that adapt to the different materials that will twine with other dissimilar tooth.

For fear of dangerous and because security reason, whole coiler is packed in the case of being made by metal sheet, and suitable video camera TV control cabin from afar controls its operation, and it links to each other so that operation is totally controlled with computer installation.
