WINDING PLANT FOR ROLLED-STOCK

Description

[0001] This invention relates to a winding plant according to the pre-characterizing part of the main claim 1.

Technical Field

[0002] This plant is particularly intended, if not exclusively, to be placed downstream of a wire, band or strip rolling-mill plant, in which instead of fly-cutting the rolled-stock, the latter is wound in coils

Background Art

[0003] In the prior art different systems are known for coil-winding the rolled-stock or also wire, for example originating from others plants, in a continuous way, citing as an example: US-A- 3,796,389 discloses an apparatus for strip winding placed in a feeding line with a split-system for two alternating winding-machines in the winding operation.

[0004] A similar plant is disclosed in DE-A-4035193 where substantially a flying cutting shear and splitting-system to split is provided, without stopping the advancement of the wire on either of the two winding-machines so that while the winding is carried out in one machine, it is possible to proceed with the extraction of the coil in the other.

[0005] Another similar plant is explained in EP1126933 in which a handling device is associated to each winding-machine to draw out axially the coil from the stopped winding-machine and transfer it to evacuating transfer means, while the other is winding. Further prior art is JP06091720 (see Patent Abstracts of Japan vol.18, no.354 (M-1632), 5 July 1994 (1994-07-05)-&JP06091720A (Mitsuboshi:KK), 5 April 1994 (1994-04-05). In this disclosure exclusive taking motors M1,M2, are provided to respective bobbins 5,6 in order to continue the tacking-up of a molded product B, even at the time of work, for replacing the bobbins 5,6. Arranging rollers 54a,54b, prescribing the posture and shape of the molded product B are provided to the loading end of a guide arm 42 in close vicinity to the bobbins 5,6 in order to be moved in the lateral direction and radius direction of the bobbins (reels). Each reel having an exterior flange realized with radial arms (27) hinged to the mandrel reel (26) to be rotate externally close to axial direction to allow extraction of the coil.

Drawbacks of the Prior Art

[0006] The known solutions have operating speed limits and moreover are structurally complex and expensive. The winding process can involve stops due to tangling and due to the fact that handling arrangements and storage of the coil are impractical and quite slow.

[0007] The machines are cumbersome.

[0008] Both systems therefore present one or more of the aforementioned drawbacks and limitations.

[0009] In particular the solution EP1126933 is very complex and inefficient particularly with the limited speed of the system for opening and closing the reel that takes place with the system in the form of a flag-opening cap, with all the resultant drawbacks. The complexity of the latter solution derives furthermore from the of pick-up and movement system of the pulled coil by means of ground guide-rails, trolleys and the like. All these embodiments make the system very complex, cumbersome and difficult to access and maintain. In conclusion, it is unreliable. The operating speed is further limited by the complex structure of systems for wire entry guidance and control of the coil after formation for pick-up.

Aim of the Present Invention

[0010] The aim of the present invention is to avoid the aforementioned drawbacks and improve the performance of the plant, to improve the quality and/or to reduce the cost of the treated material.

Summary of the Invention

[0011] The winding plant according to the present invention is concretized according to the characteristics of the main claim 1.

[0012] The characteristics of the sub-daims refer to particularly advantageous solutions.

Advantages

[0013] The advantages obtained achieve the pre-established aims and in particular allow a high functional performance to be achieved and moreover allow a qualitatively good product to be obtained at a reduced production cost.

[0014] All this is obviously favoured by the vertical axis coil extraction system.

Detailed Description of the Plant in Connection with the Figures

[0016] As disclosed in the previous Figures, the winding plant (see Fig. 1 -1A, 2-2A) includes a split system or splitting of the known type with a flying shear, schematized with (1) that deviates the wire on two lines, alternatively on one or on the other (2) towards one or the other of two respectively adjacent winding-machines (4), with the aid of suitable wire-guide means of the known type (3) for the coil-winding (B).

[0017] While a coil forms in a winding-machine, in the adjacent winding-machine that is stopped, the pick-up of the completed coil is carried out, with transfer (5', .., 521).

Coil Transfer (5. Figg.1, 1A, 2, 2, 2A, 3B, 3A, 3B, 3C)

[0018] The coil transfer (5' ..., 521)Fig.1,521)Fig.1,1A, is of the portal type, namely with a column (51), with a rotary flag-type arm (S2-510), whose end (521) carries an opening clamping device with a couple of clamps or cross-opposite jaws (522) for the pick-up and axial extraction of the coil (B) from the winding-machine (AV) of the respective winding device (4, 4a) to transfer it (Fg2) from the stopped winding-machine to a tie/binding back-station by means of two known art opposite binding machines or tie-machines (6) Fig.2A, being provided furthermore with the transfer of the coil to the respective storage of tied coils (B1).

[0019] The mullion-transfer is therefore of the portal type and its rotating arm (52) can be raised and lowered by means of a dynamic-fluid piston (520) for the pick-up and deposition action, while rotation is guaranteed by respective motor/ratiomotor (510) at the base of the column on respective thrust-bearing (5101).

[0020] The lifting and lowering of the arm (52) being assured by a folded-plate guide (520) with pairs of guide opposite rolls (5201) operating in a sliding way on the column in double-T section.

[0021] The pick-up of the coils is facilitated by the clamping device with four clamps that self-centre on the coil (B), opening and closing by means of respective opening and closing fluid operated cylinders (5220).

[0022] In this way it is understood that the movement of the transfer is very fast and given that it has open-air excursion, it does not encumber or hamper the surrounding zones allowing moreover greater compactness of the plant. Furthermore, the type of movement is manifestly very simple and very reliable with greatly reduced maintenance.

Winding Groups (4, 4A, 48, AC, Fig.4. 4A, 5, 6, 6A)

[0023] The two winding groups are identical and adjacent with a wire-winding reel (F) having a reel that can be opened (AV) with a vertical axis.

[0024] Each group includes in addition to the central winder (AV-41) two opposite coil-compacting apparatus (4b) in couples of rolls (422) and two auto-introducing wire-guide jaws to automatically guide the wire at the beginning of winding (4C).

[0025] In the centre the reel (41) is found with openable winding reel (AV).

Opposite Coil-Compacting Apparatus (4B)

[0026] They include two respective articulated devices (42), placed on one side and one on the other of the winding reel (AV) with respect to the advancing line wire that fits sideways into the reel (AB).

[0027] The rolls are mounted on an articulated arm (421) hinged to the base structure (420) and operated in rotation from a spaced position (Fig.4) to a position against the coil (B) Fig.6. The movement occurs by means of a base dynamic-fluid cylinder (4212) on a reacting arm (4210).

[0028] Said rolls (422, see Fig.6A) being a pair mounted on a parallelogram (4222) in couples of opposite arms mounted on support rolls (4220) and moved elastically under pressure by respective means with dynamic-fluid cylinder (4221).

[0029] In this way the movement is simple and reliable and the orientability of the rolls guaranteed to be unchanged for the suitable control of the end turns of the coil (B) in the winder (4V-41) to avoid the slackness prior to pick-up.

Wire-Guide Group (4C)

[0030] The wire-guide group includes two guide opposite jaws entrance semicircular wire (431) hinged sideways horizontally (430) and controlled by a fast-moving dynamic-fluid cylinder (4311) at the end of the movement arm jaw (4310) hinged sideways to the base machine (4301) and rotated in sending-away and approach by means of a resending arm (43101) operated by fluid-operated base-cylinder (43102).

[0031] In this way it is understood that while with the opposite fluid operated base-cylinders (43102) the sending-away and approach of the drive-introduction jaws wire (431) is carried out, their final movement being precise and fast in order to engage and disengage the wire, with independent, short precise and fast action (4311) that would otherwise prove impossible with this type of performance by the approaching and spacing-apart mover device with wide excursion (43102).

[0032] Therefore, the above allows a very high speed and good performance to be achieved, without danger of tangling or the need to reduce the advancing speed of the wire or use of adapting wire-loops speed.

[0033] The short engaging and disengaging movement is clearly visible in Fig.5

Central Winding Group - Winding Reel (4A, Figg. 7, 7A, 7B, 8)

[0034] It comprises the central winding reel (41) with a closable and openable reel (AV), Opening and closing of the reel (AV):

[0035] Once the opening and closure of the reel (AV), necessary to extract the coil (B) has been completed, occurring by means of four rotatable petal flange sectors (411) with a reacting arm (4111) moved by a sleeve (413) that moves axially by means of a dynamic-fluid cylinder (4131-4132) operated by a dynamic-fluid circuit (4133) with transmission to the base reel (41330) on a non-rotating coaxial axis with respect to the rotating reel (AV).

[0036] The advantage of this solution is very important for the compactness and simplicity of the rotation guaranteed by the connection shaft end (4131) with respect to the sleeve (413).

Variation of the External Shape of the Reel Mandrel (AV)

[0037] The reel mandrel (AV) is composed of four sectors, namely four nippers (410), hinged to the base (4121) of a flange rest-coil lower reel (412).

[0038] On the upper part the reel-mandrel movable sectors (410) are articulated (4112) to said axially movable sleeve (413).

[0039] In this way, when the movable sleeve (413) is raised the upper flanging petals (411) are open, namely orthogonal to the reel axis and allow coil formation (B) during winding, and the sectors of the reel-mandrel (410) are parallel and form a cylinder (Fig.7).

[0040] When the coil is finished, to allow easy extraction, the movable internal sleeve (413) withdraws downwards simultaneously operating:

• the petals of the upper flanging of the reel that close upwards like a flower,
• the sectors of the core that re-enter on the upper part (410, Fig.7A) determining a conical shape with an upper base size less than the lower base.

[0041] In this way the extraction of the coil (B) is allowed and facilitated by means of the jaws of the clamping device (522).

Cooling System

[0042] The sectors or nippers of the semicircular shaped reel mandrel (410) are internally holed with channels (4102). The channels convey on a connecting duct (41020) with a duct inside a double coaxial channel (41021, 41022).

[0043] In this way the cooling of the reel is guaranteed.

[0044] Furthermore the external shape of said core nippers or sectors is undulated by means of alternate longitudinal tanglings (4101).

[0045] In this way the contact of the surface of the reel mandrel (AV) with the coil (B) is reduced and a circulation of air through these longitudinal tanglings is facilitated.

[0046] The reel (AV) rotates coaxially to the central axis by means of motorization of the type known with connection to bevel-type drive (40, 401-402).

Winding Cycle

[0047] The start of coil-winding occurs by means of said device with movable semicircular opposite jaws (431) in association with the wire-introduction system (AB) for first adherent turns to the base side or flange of the reel (AV) of the winding-machine.

[0048] This device receives the wire (F) from the dispenser (2-3) while it is closely fitted to the reel mandrel (AV) and subsequent to the priming of the first turn, it must quickly free the coil forming area. To do this with maximum efficiency, the fast movement of rapid displacement (short rotation 4310, Fig.5) is used.

[0049] Subsequently, with other slower and wider rotation movements (4310-43102) the wire-guide jaws sending-away is carried out, leaving free the space to the approach said control rolls' last coil turns (422).

[0050] In this way when the coil stops, the last turns are held closed until the clamping device (522) of the transfer (5) intervenes, whose four jaws are rotated to 45° to clamp the coil (B) between said rolls (422).

[0051] Subsequently, the rolls (422) move away and the coil (B) still remains clamped by the clamping device. At the same time the reel (AV) is also opened thus tightening and closing the upper flanging petals that are oriented upwards.

[0052] In this way the closed coil is also loosened internally and it can be easily removed upwards with the lifting of the arm (52) of the mullion-transfer (5) and it can be rotated rearward for the deposition into the binding-machine with two opposite binding groups (6).

[0053] At this point the cycle repeats thus returning the priming wire-guide jaws in the position adjacent to the reel mandrel (AV) to receive a new wire (F) to wind (Fig.4).
