Description

The The present invention relates to a winding machine according to the preamble of the main claim 1.

field of use

These Plant is especially, if not exclusively, meant to be one Wire or strip rolling mill to be followed in the place Fly-cutting the Walzguts latter is wrapped in coils.

State of the art

In the prior art, various systems for continuous coil winding of rolling stock or wire are known, for example from other systems, for example:
US-A-3 to 796.389 discloses a device for tape winding in a feed line with a split system for two winding machines alternating during winding.

A similar facility will be in DE-A-40 35 193 Essentially, there is provided a flying shear and a splitter system which does not stop the advancement of the wire on one of the two winding machines, so that while one is being wound, one can pass in the other to extend the waistband.

Another similar facility will be in EP1126933 explains that a handling device is connected to each winding machine to pull the collar axially out of the stopped winding machine and transfer it to discharge means while the other winds.

US4964587 and USB63186601 reveal machines with winding devices.

Especially USB63186601 discloses a winding device with wire input guide ( 37 . 39 . 40 . 42 . 43 ).

Disadvantages of the prior art

The known solutions have operating speed limits and are also structural complex and expensive.

The Wrapping may include stops, due to tangling, and the handling arrangements and bedding storage are impractical and rather slowly.

The Machines are bulky.

Both Systems therefore have one or more of the disadvantages mentioned above and restrictions on.

In particular, the solution of EP1126933 is very complex and rather inefficient, especially because of the limited speed of the reel opening and closing system that takes place with the system in the form of a flag-like opening cap, with all the resulting drawbacks. The complexity of the latter solution also stems from the receiving and moving system of the molded collar by means of floor guide rails, trolleys and the like forth. All these forms make the system very complex, bulky and hard to access and maintain. In summary, it is pretty unreliable. The speed of operation is further limited by the complex structure of the wire entry guide systems to introduce the head of the wire at the start of winding (guiding the head of the wire to be inserted at the beginning of bunching). The two opposite semicircular wire input guide means 37 . 39 . 40 from US6318660 use a single large movement to approach the reel or move away from the reel by means of a rotary arm coming from the cylinder (FIG. 42 . 43 ), and ripple control after the formation of the Confederation.

Object of the present invention

The The aim of the present invention is to overcome the abovementioned disadvantages to avoid and improve the performance of the plant and the quality and / or to reduce the cost of the treated material.

Summary of the invention

Of the Winding system according to the present invention is according to the Characteristics of main claim 1 given a definitive form. The characteristics the dependent claims refer to particularly advantageous solutions.

advantages

The solved advantages the preconceived goal and in particular allow the achievement of a high multifunctional performance and also a good quality Products with reduced production costs.

This becomes obvious from the bundle extension system with vertical axis favored.

Full Description of the system in connection with the figures

As disclosed in the previous figures, the winding machine (see 1 - 1A ; 2 - 2A ) a splitting system of the known type with a flying shear, which ( 1 ) is schematic and redirects the wire to two lines, alternatively one or the other ( 2 ) to one or the other two adjacent winding machines ( 4 ), by means of suitable wire guide means of the known type (US Pat. 3 ) to the coil winding (b).

While a covenant forms in a winding machine, in the adjacent Wickelma which is stopped, the admission of the completed Confederation with transfer ( 5 ; ...; 521 ) carried out.

Bund transfer ( 5 . 1 . 1A ; 2 . 2A ; 3A ; 3B . 3C )

The federal transfer ( 5 ; ...; 521 ) 1A is with portal, with a pillar ( 51 ), with a flag-like arm ( 52 ), which turned ( 510 ), whose end ( 521 ) an openable vise with a pair of clamps or jaws (FIG. 522 ) for the reception and the axial extension of the collar (b) from the winding machine (AV) of the winding device ( 4 . 4A ) to you ( 2 ) from the stopped winding machine to a downstream binding or flat steel belt station by means of two opposing binding machines or tractors of the prior art ( 6 ) 2A on which the bundle transfer is provided for the storage of tied coils (B1).

The post transfer is therefore with portal, and its rotating arm ( 52 ) can by means of a liquid piston ( 520 ) can be raised and lowered to receive and store while the rotation of a motor / ratiomotor ( 510 ) at the base of the column on a pusher block ( 5101 ) is guaranteed.

The raising and lowering of the arm ( 52 ) is controlled by a cassette guide ( 5200 ) with pairs of opposite guide rollers ( 5201 ), which glide on the column with double T-section.

The reel pick-up is facilitated by the four-clip clamping device self-centering on the collar (b) opening and closing by liquid cylinder for opening and closing ( 5220 ).

hereby becomes understandable that the transfer movement is very fast and short open air movement Therefore, it does not obstruct the surrounding areas, which is a even greater compactness the plant allowed. Furthermore This type of movement is obviously very easy and very reliable with to a minimum of reduced maintenance.

Winding groups ( 4 . 4A . 4B . 4C . 4 . 4A ; 5 . 6 . 6A )

The Both winding groups are identical and adjacent to a wire winding reel (F) with one openable Reel (AV) with a vertical axis.

Each group comprises, in addition to the central winding reel (AV- 41 ), two opposing collar compactors ( 4B ) in pairs of rolls ( 422 ) and two self-feeding wire guide jaws to secure the wire at the beginning of winding ( 4C ) automatically.

In the middle is the reel ( 41 ) with open winding reel (AV).

Opposite collar compacting device ( 4B )

They comprise two hinged devices ( 42 ) placed on either side of the winding reel (AV) with respect to the wire advancing line which fits laterally in the reel (AB).

The rollers are on a limb ( 421 ) mounted with the basic structure ( 420 ) is hinged ( 420 ) and from a position at a distance ( 4 ) is rotated in a position against the collar (b) 6 , The movement takes place through a base liquid cylinder ( 4212 ) on the reacting arm ( 4210 ).

Said roles ( 422 , please refer 6A ) are in pairs on a parallelogram ( 4222 ) mounted on pairs of opposite arms which are supported on support rollers ( 4220 ) are mounted and elastically under pressure by means of liquid cylinder ( 4221 ) are moved.

In this way, the movement is simple and reliable, and the unchanging orientation of the rollers is for the proper control of the federal government's final turns (b) in the winding reel (FIG. 4V - 41 ) in order to avoid slack before admission.

Wire guide group ( 4C )

The wire guide assembly comprises two semicircular opposed wire entry jaws ( 431 ), which are articulated laterally and horizontally ( 430 ) and from a fast-moving liquid cylinder ( 4311 ), at the end of the jaw movement arm ( 4310 ), which is laterally aligned with the base of the machine ( 4301 ) is articulated, and by means of a reacting arm ( 43101 ) is turned back and forth again by a base liquid cylinder ( 43102 ) is driven.

As a result, it is understood that while with the opposed liquid-driven base cylinders ( 43102 ) the removal and approach of the wire entry jaws ( 431 ), their final movement, which is precise and fast to insert and disengage the wire, with independent, short, accurate and fast ler control ( 4311 ), which would otherwise be impossible in this type of process, from the extended-range approaching and 43102 ).

The The above therefore allows very high speed and excellent Performance, without the risk of entanglement or the need to the advancing speed reduce the wire or the need for speed adjustment loops to use.

The short entry and unthreading movement is in 5 good to see.

Medium winding group winding reel ( 4A . 7 . 7A ; 7B . 8th )

It includes the central winding reel ( 41 ) with the lockable and open reel (AV), reel opening and closing (AV):
The opening and closing of the reel (AV), which is necessary to extract the collar (b) after completion, is effected by four rotatable blade flange sectors, ( 411 ) with a reacting arm ( 4111 ), of a sleeve ( 413 ) is moved axially by means of a liquid cylinder ( 4131 - 4132 ), which is driven by a dynamic fluid circuit ( 4133 ), with transmission to the reel base ( 41330 ) on a coaxial non-rotating axis with respect to the rotating reel (AV).

The advantage of this solution is very important for compactness and simplicity, whereby rotation through the connection wave end ( 4131 ) with respect to the sleeve ( 413 ) is guaranteed.

Coiler mandrel: outer shape change (AV)

The coiler mandrel (AV) consists of four sectors, four squeeze rolls ( 410 ), with the base ( 4121 ) of a lower collar support reel flange ( 412 ) are hingedly connected.

On the upper part are the movable sectors of the coiler mandrel ( 410 ) on said axially movable sleeve ( 413 ) ( 4112 ).

In this way, when the movable sleeve ( 413 ), the upper flange blades ( 411 ) open at right angles to the reel axis, and allow the rounding (b) during winding, and the reel-mandrel sectors (FIG. 410 ) are parallel and form a cylinder ( 7 ).

• – die Blätter des oberen Flanschs der Haspel, die sich wie eine Blume wieder nach oben schließen,
• – die Sektoren des Kerns, die auf das Oberteil (410, 7A) zurückkehren, so dass eine konische Form entsteht, deren obere Basisgröße kleiner als die untere Basis ist.

When the collar is finished, the movable inner sleeve (to permit easy extension) ( 413 ) retracted downwards, simultaneously driving:

• The leaves of the upper flange of the reel, which close up again like a flower,
• - the sectors of the core that are on the top ( 410 . 7A ), so that a conical shape is created whose upper base size is smaller than the lower base.

In this way, the Bundausziehen (b) by means of the jaws of the clamping device ( 522 ) allows and facilitates.

cooling system

Semicircular coiler mandrels or squeezing rollers ( 410 ), are inside with channels ( 4102 ) perforated. The channels move on a connecting line ( 41020 ) with a line in a double coaxial channel ( 41021 . 41022 ). In this way, the cooling of the reel is guaranteed.

Moreover, the external shape of the nip rolls or sectors is by means of alternating longitudinal shafts ( 4101 ) corrugated.

On in this way the contact of the coiler mandrel surface (AV) with the collar (b) is reduced, and the air circulation through these longitudinal shafts is relieved.

The reel (AV) rotates coaxially to the central axis by means of a motor according to the prior art with connection to a bevel gear ( 40 . 401 - 402 ).

wrapping cycle

The coil winding start takes place by the movable semicircular opposing jaw device ( 431 ) in connection with the wire insertion system (AB) for the first adjacent turns on the base side or on the flange of the reel (AV) of the winding machine.

This jaw device ( 431 ) receives the wire (f) from the distributor ( 2-3 ) while snugly resting on the coiler mandrel (AV), and after preparing the first turns, it must quickly clear the banding surface. To do this as efficiently as possible, the fast movement of fast displacement (short rotation 4310 . 5 ) used.

Subsequently, with further slower and more expansive rotational movements ( 4310 - 43102 ) carried out the removal of the wire guide jaws, leaving the space for the approach of the last coil windings of the control rollers ( 422 ).

That way, when the covenant arrives holding the last turns closed until the clamping device ( 522 ) of the transfer ( 5 ), the four jaws of which are turned 45 ° in order to move the collar (b) between the rollers ( 422 ) to cling.

Then the rollers move ( 422 ) and the collar (b) remains closed by the clamping device.

simultaneously the reel (AV) is also opened and thus tighten the upper flange leaves and close them, which are oriented upwards.

In this way, the locking collar is also loosened inside and can easily with the lifting of the arm ( 52 ) of the post transfer ( 5 ) withdrawn upward and for storage in the binding machine with two opposite binding groups ( 6 ) are turned backwards.

At this point, the cycle is repeated, returning the preparation wire guide jaws to the position adjacent the coiler mandrel (AV) to receive a new wire (f) and ( 4 ) to wind.
