Description

Improved Coil Delivery Coiler for Rolled Products

technical field

The invention relates to a coil conveying and coiling device for rolled materials.

Such a device is intended in particular, but not exclusively, to be placed downstream of a rolling production plant for wire or strip, in which the rolled material is not rapidly cut but rolled into coils.

Background technique

A number of different systems are known in the prior art for coiling in a continuous manner e.g. rolled and wire rod from other installations, the following are cited as examples:

US-A-3,796,389 discloses a device for strip coiling placed in a feed line with a separation system for making two coilers work alternately with each other during coiling.

A similar device is disclosed in DE-A-4035193, which actually provides a flying shear and a separation system for separation, without stopping the advance of the wire on either of the two coilers, so that when carried out in one machine When coiling, it can be taken out in another machine.

Another similar arrangement is described in EP1126933, in which handling means are connected to each coiler to axially withdraw the coil from a stopped coiler and to transfer said coil away so that the transfer device is emptied, At the same time, another coiler is coiling.

The prior art related to coil conveying column has: USA2126528; GBA1047571; USA3105653; Japanese patent abstract vol.1996, no.06, 28, June 28, 1996 (1996-06-28) and JP8039146A;

Known solutions have a speed limit of work and are also structurally complex and expensive.

The coiling process stops due to tangling, handling arrangement and coil storage are impossible and very slow.

The size of the machine is large.

Both systems thus suffer from one or more of the aforementioned disadvantages and limitations.

In particular, the solution of EP1126933 is very complex and inefficient, with all the above-mentioned disadvantages due to the limited speed of the opening and closing action of the reel due to the system in the form of a flag-shaped cap. The latter solution is also complicated by the use of floor rails, trolleys and the like for the pick-up and movement system of the formed coils. These approaches make the system complex, bulky and difficult to use and maintain. The conclusion is that it is not reliable enough. The complex structure of the wire entry guide system and the coil pick-up control system after forming also limits the speed of the operation.

Contents of the invention

The object of the present invention is to avoid the aforementioned disadvantages, to improve the performance of the device, and to improve the quality and/or reduce the cost of the material to be processed.

According to the present invention, there is provided a coiling device for rolled material, which comprises, downstream of the rolling equipment: a quick cutting device for the rolled material and a two-way separating device; a coiled wire rod entering guide device; at least two Coilers for forming rolls, wherein each coiler includes a roll core including an outer flange that can be opened so that the roll can be removed when complete, so The coiling machine is connected with a movable wire entering guide for starting coiling to form a coil; a coil transfer device can take the coil out of the coil core and transfer the coil to another place; it is characterized in that: said coil conveying device is revolving door shape, and it has column, and column has flag-shaped arm, and said flag-shaped rotating arm is equipped with the device that makes it can be raised and lowered, and in arm's The ends include engagement means for gripping by opposing jaws or talons, which are substantially transverse and openable to grip one of said coils, to hold said coils The material is taken from the reel core of the coiler, rotated outwards and placed in the corresponding other working area; bringing said opposed movable rollers from a remote upwardly rotated position to a position against a web formed in said mandrel core, said rollers being mounted on opposed parallelogram joints on roller mounts Mechanistically, the dynamic fluid cylinder device abuts the web during coiling until the opposing gripping jaws grip the web for removal from the roll core, gripping the roll The coils between them; the conveying device cooperates with the strapping machine to bundle the coils in the transverse clamps with two opposite strapping groups.

The advantages obtained address the aforementioned objectives, in particular that efficient multifunctional properties can be obtained and that products of good quality can be produced at reduced manufacturing costs.

All these advantages are clearly facilitated by the vertical axis coil take-off system.

Detailed ways

As disclosed in the above figures, the coiling device (see Figures 1-1A, 2-2A) includes a separation system or a known type of separation with flying shears, this separation system or flying shears indicated by 1 separates the wire Separated into two lines, by suitable wire guides 3 of known type, either on one line or on the other line 2, the wires go towards either of two adjacent coilers 4, respectively, so that Do coil B.

While a coil is being formed in one coiler, the adjacent coiler has stopped and the finished coils are picked up with conveyors 5 , . . . , 521 .

Coil conveyor (5, Fig. 1, 1A, 2, 2A, 3A, 3B, 3C)

The coil conveying device 5 of Fig. 1A, ..., 521 is gate type, promptly has column 51, and has the flag-shaped arm 52 of rotation, and arm 52 ends have the clamping device that can open, and this clamp The holding device has a pair of grippers or laterally opposite claws 522 for picking up and axially withdrawing the coil B from the coiler 4 of the corresponding coiling device 4, 4A, said coil ( FIG. 2 ) from In the stopped coiler, the bundling or bundling position is transferred to the back, and the bundling is carried out by two oppositely arranged bundling machines or bundling machines 6 of the known technology of Fig. 2A, and then the coils are sent to each bundle. Bale coil B1 storage place.

The mullion conveyor is therefore of the gate type, and its swivel arm 52 can be raised and lowered by dynamic fluid pistons 520 for pick-up and settling actions, while being secured by corresponding motors/variable motors 510 on corresponding thrust blocks at the bottom of the columns. its spinning.

By means of a box guide 520 with a pair of opposing guide rollers 5201, which work in a sliding manner on a double T-section column, the raising and lowering of the arm 52 is guaranteed.

Easy coil pick-up thanks to clamping unit with four jaws, self-centering of the jaws on coil B and release and closing of the jaws by means of corresponding fluid-operated cylinders for release and closing .

It will be appreciated that the conveying movement in this way is very fast and works openly, it does not hinder or obstruct the surrounding area, thus also making the whole device more compact. In addition, such movement is obviously simple and stable, and reduces maintenance costs to a minimum.

Coil Group (4, 4A, 4B, 4C, Figure 4, 4A, 5, 6, 6A)

The two take-up groups are identical and adjacent, with wire take-up reels F with openable reels AV and with vertical axes.

Each set includes, in addition to the central roll mandrel AV-41, two opposing roll hold-down devices 4B in the form of pairs of rollers 422, and two automatically introduced wire guide claws for The wire is automatically guided at the beginning of coiling 4C.

In the center is the bobbin 41 with the openable take-up core AV.

Opposite Coil Holder 4B

They comprise two respective articulated means 42 placed on both sides of the take-up mandrel AV with respect to the wire advance line adapted laterally to the reel AB.

The rollers are mounted on articulating arms 421 hinged to the base structure 420 and the rollers rotate from the remote position ( FIG. 4 ) to the abutting position against the web B in FIG. 6 . This movement is produced by the fluid operated bottom cylinder 4212 on the reaction arm 4210.

The rollers 422 (see FIG. 6A ) are installed in pairs on the parallelogram joint mechanism 4222, and the opposite arms of the pair are installed on the roller support 4220 and are elasticized under the pressure of the corresponding dynamic fluid cylinder device 4221. move.

Such movement is simple and stable, and ensures constant positioning of the rollers to properly control the end turns of coil B in the take-up mandrel 4V-41, avoiding slack before pick-up.

Wire guide group 4C

The wire guide set consists of two semicircular opposing wire entry guide claws 431 which are horizontally 430 hinged to the side and are driven by a rapidly moving end of the claw moving arm 4310 which is laterally hinged at the bottom 4301 of the machine. The dynamic fluid cylinder 4311 controls the rotation of the reaction arm 43101 operated by the fluid operated bottom cylinder 43102 to move away and approach.

It can thus be understood that although the wire entry guide talons 431 are moved away and approached by the opposing bottom cylinders 43102, their ultimate movement, that is, the accurate and rapid engagement and disengagement of the wire, depends on independent, short, precise And rapid control device 4311 realizes, if approaching and departing from moving device 43102 with large stroke, then can not realize the final movement of above-mentioned performance.

Therefore the above can obtain high speed and good effect without tangling, or without reducing the advance speed of the wire, or without using a speed adjusting looper.

The brief engaging and disengaging movements are clearly visible in FIG. 5 .

Take-up Center Group - Take-up Reels (4A, Figure 7, 7A, 7B, 8)

It consists of a central take-up bobbin 41 with a closable and openable bobbin core AV whose opening and closing action:

The opening and closing of the mandrel core AV, necessary to remove the coil B once it is complete, is produced by four rotating petal flange parts 411, internal linkage articulation 4111 by means of sleeves 413 while the sleeve is moved axially by means of dynamic fluid cylinders 4131-4132 operating through a dynamic fluid circuit 4133 delivered to the drum base 41330 on a non-rotating common axis relative to the rotating drum mandrel AV .

The advantages of this solution are important to ensure compactness and simplicity of rotation by means of the rod end connection 4131 relative to the sleeve 413 .

AV shape change of reel core

The roll core AV consists of four parts, namely four pincers 410 which are hinged on the bottom 4121 of the lower roll flange 412 on which the roll rests.

In its upper part, the movable part of the roll core 410 is hinged 4112 on said axially movable sleeve 413 .

In this way, when the movable sleeve 413 is raised, the upper flange petals 411 are opened, i.e. perpendicular to the axis of the reel so that the roll B can be formed during the coiling process, the reel core part 410 is parallel and forms a cylinder barrel (Figure 7).

When the coil is finished, for easy removal, the movable inner sleeve 413 is retracted downwards while operating:

- the upper flange petals of the roll are closed upwards like a flower,

- The re-entrant core at the upper part 410 (FIG. 7A) defines a conical shape with the upper base smaller than the lower base.

This makes it possible and easy to remove the coil B by the claws of the holding device 522 .

cooling system

The semicircular mandrel core portion or tongs 410 are perforated internally to form channels 4102 . This channel is connected to the double coaxial channels 41021, 41022 of the inner tube by means of the connecting tube 41020.

This ensures cooling of the reel.

Additionally, the profile of the core or pliers is undulated by alternating longitudinal counterbores 4101 .

This reduces the contact of the surface of the roll core AV with the web B and facilitates the circulation of air through these longitudinal counterbores.

The mechanization of bevel gear drives 40, 401-402 is connected by means of known techniques, so that the mandrel core AV rotates coaxially with respect to the central axis.

coiling cycle

The start of coiling is through said movable semicircular opposing claw means 431 connected to the wire introduction system AB, connecting the first turn to the side of the coiler or the flange of the bottom bobbin mandrel AV.

When the wire F is tightly fitted on the reel core AV, and after the first turn has started, the device receives the wire F from the dispenser 2-3, the area where the coil is formed must be emptied quickly. In order to do this in the most efficient way, rapid movements of rapid displacements (short rotations 4310, Fig. 5) are used.

The wire guide claws are then moved away with other slower and farther-travel rotary motions 4310-43102, freeing up space so that the last coil turn 422 of the control roller can be approached.

Thus when the web stops, the last turn remains closed until the intervention of the clamping device 522 of the conveyor 5, the four claws of which are rotated by 45° to clamp the web B between said rollers 422 .

The rollers 422 are then removed while the web B is still held closed by the clamping means. At the same time the mandrel core AV is also opened to fasten and close the upwardly positioned upper flange petals.

In this way the stopped coils are also loose inside and are lifted by the arms 52 of the mullion conveyor 5 to be easily moved upwards and rotated backwards to settle in the baler with the two opposing baling groups 6 .

The cycle is now repeated, returning the original wire guide jaws to a position adjacent to the spool core AV to receive a new wire F for coiling (Fig. 4).
