Description

The present invention relates to a coil winding introducer for the precharacterizing part of the main claim.

This introducer is particularly intended, if not exclusively, to be placed below a cable or strip or strip of a rotary mill introducer, in which instead of the laminate cutting tool, the most recently used is wind-blown.

In the prior art different systems are known for coil winding of a laminated material and also wire, for example originating from other introductors, in a continuous manner, citing US Pat. No. US-A-3,796 as an example. 389 disclosing a device for tuning the winding of the bobbin placed on a feed line with a divider system for two winding machines alternating with each other during winding.

A similar introducer is disclosed in DE-A-4035193 where substantially the cutting tool laminates the splitter system to provide breakage without paralyzing the progress of the wire or wire or also two coil winding machines so that the winding It is performed on one machine, and the coil can be extracted on the other.

Another similar introducer is shown in EP 112693 in which a hand-held apparatus is associated with each winding machine to axially withdraw the coil from the paralyzed winding machine and transfer said coil to evacuate transfer means while the other is winding. The known technique for coil transfer is disclosed by US Pat. GBA1047571; USA3105653; and Patent Abstract of Japan, vol. 1996, No. 06, June 28, 1996 (June 28, 1996) &JP8039146A; WO96 / 30137A.

Known solutions have operated fast limits and even more are structurally complex and costly. The winding process may involve downtime due to embarrassing arrangements and coil storage that are not only practical but very slow and the machines are very bulky.

Both systems have one or more of the above obstacles and limitations.

In particular, EP1126933 solution is very complex and inefficient particularly with the limited speed of opening and closing of the carriage which occurs with the system in the form of an indicator opening lid, with all resulting inoperative. The complexity of the above solutions derives further from the coil loading motion system being formed by means of guide rail areas, pulleys and the like. All these forms make the system very complex, cumbersome and difficult to access and maintain. Concluding are uncertain. The speed of operation is further limited by the complex frame systems for conducting the wire or wire to control the coil after forming for its loading. The object of the present invention is to prevent the discomforts described above, to improve introducer performance and to improve the quality and / or to reduce the cost of the treated material. The coil winding introducer according to the present invention is embodied in accordance with the features of the main claim.

The features of the other claims relate in particular to advantageous solutions.

The advantages achieved address the particular goal set by enabling high multifunctional performance to accomplish and even more allowing a very good quality product to be obtained at a reduced production cost.

All of this is obviously favored by the vertical axial extraction system.

The features of the invention and other relevant features will be better understood with reference to the drawings included herein, which show by way of example, but not limitation, in which: - Figure 1 is a schematic side view of the winding introducer applied to the extreme part of a rotary grinder line during the winding or winding phase in the first winding machine of two coordinate adjacent winding machines supplied by a key guard with associated sharpened shearer; Figure 1a depicts the coil depositing phase at the connection station; Figure 2 is an overview of the introducer of Figure 1, in which it is possible to see the two adjacent winding machines associated with a signal protractor, particularly with a column with a rotatable arm designed to extract the coils from other winding machines and unloading said coils a further connection, and / or transferring to the material and stock station in Figure 2A. Figures 3A and 3B show, in an elevated side view, the transfer of the vertical bar with the previous figures, respectively without coil, decreased and with the coil increased for transfer by rotation. Figure 3C is a view of an introducer of an apparatus for loading a four-jaw coil, placed at the end, under a portal arm of a vertical bar transfer apparatus; Figure 4A represent respectively a plan and elevated side view of the winding machine from the feed side of the wire or wire to be blown, with the pair of wire guide jaws lowered from the wire winding reel. to allow the automatic splitting of the yarn division by the fine-sheared shearing (40-2.3), while the pair of rollers holding the spool compact at the winding end are upwardly rotatable at a distance from the winding reel (4B -422); Figure 5 is a view of the immediately following phase of threading and start of winding (F), opposite wire guide jaws (4C-431) immediately being added with a small untangled movement from the previous opposite wire guide jaw , being this movement very fast since it is not integrated in the total untangled mechanism that happens in the next phase; Figures 6 and 6A represent a view of the same device as shown in the previous Figures, but in which the opposing jaws are completely rotated by rotation in a different joint, sending out the winding carriage (AV), while the two opposing pairs of rolls (422) have been moved in approach against the yarn bobbin which is formed in rotation (B); Figure 7 is an enlarged view of constructive details of a wire winding reel for winding (winding reel) in a partial axial section to show the respective movement of the cooling mechanism and device. Said winder or reel and winding being in the winding position; Figure 7A is a view of the take-up reel (AV) as shown in the previous figure, in which the axial partial section and the movement of the mechanism are still visible and the latter has been transformed from a closed to a tapered reel (410). and the edge of the reel (411) is pivoted upward, mainly toward the existing and outwardly to allow axial extraction of said coil (B); Figure 7B is a plan view of the reels or mandrel sections of the reel, of which four form the reel reel in a movable manner, particularly the reel reel mandrel with a created view of the respective inner holes, these channels being for cold water circulation and then with the dispersion of hot water which introduces heat into the coiled wire, introducing into the coil winding, together with the special outer wavy shape of said tweezers, to minimize contact with the wire or wire and allow improved heat dispersion by aeration; Figure 8 is a front view of a reel clamp (410), with a view of the respective channeling of the internal coil (4102) for cooling.

As shown in the above-described Figures, the winding introducer (see Figures 1-1 A, 2-2A) includes a separation or break system of the type known as a tuned shearer, schematic with (1) that deflects the wire in two lines, alternatively on one or the other (2) towards the two adjacent winding machines (4) for the purpose of usable known wire guide means (3) by coil winding (B).

While a coil forms and a winding machine, the adjacent winding machine is paralyzed, the full bobbin loading is performed with the transfer (5, ..., 521).

Coil transfer (5, Figure 1.1A, 2, 2A, 3 A, 3B, 30. The coil transfer (5, ..., 521) of Figure 1A is a portal type, particularly with a column (51) with a rotatable signaling arm (52) (510) whose end (521) carries an opening clamp device with a pair of opposite crossed clamps or jaws (522) for loading the axial extraction of the coil (B) from the winding machine (AV) of the respective winding apparatus or device (4, 4A), to transfer said coil (Figure 2) from the paralyzed winding machine to a subsequent docking or laying station by means of two connecting machines known from the prior art (Figure 2A), the transfer of the coil to the respective storage of the attached coils (B1) is then provided The transfer of the vertical and then portal type bar and its rotary arm (52) may be increased or decreased. by means of a fluid piston din malic (520) for loading and depositing action, while rotation is guaranteed by respective motor / radiomotor (510) in a column based on a momentum blocker (5101). Lifting and lowering of arm (52) is ensured by a guide box (520) with pairs of opposing guide rollers (5201) slidingly operating the column with a double-T section. Loading of the coils is facilitated by the four-clamp centering fastener on the coil (B), opening and closing by means of the fluid-operated opening and closing cylinders (5220).

In this way, it is understood that the transfer of motion is performed rapidly having an air vent which does not prevent surrounding areas but still allows for greater introducer compactness. Moreover, this type of movement is clearly very simple and very safe and reliable with its maintenance kept to a minimum.

Winding groups (4, 4A, 4B, 4C, Figures 4, 4A, 5, 6, 6A).

The two winding groups are identical and adjacent with a winding wire reel (F) with an open reel (AV) with a vertical axis.

Each group includes, in addition to the central take-up reel (AV-41), two opposing coil compact devices (4B) in the roll pair (422) and two wire guide jaws to automatically guide the wire to the start of winding (4C).

In the center is the reel (41) with the openable winding reel (AV).

Opposite Coil Compaction Device (4B) They include two hinged appliances (42) placed on either side of the take-up reel (AV) with respect to the advance of the yarn line being attached to the sides of the reel (AB).

The rollers are mounted on an articulated arm (421) joined to the base of the frame (420) and operated in rotation from the spaced position (Figure 4) to an opposite position of the coil (B) (Figure 6). Movement occurs through a fluid-operated cylindrical base (4212) in the reaction arm (4210).

Said rollers (422, see Figure 6A) are mounted in pairs on a parallelogram (4222) with pairs of opposite arms mounted on roller support (4220) and elastically moved under pressure by the respective dynamic fluid cylindrical means (4221).

In this sense, the movement is simple and reliable and invariably guaranteed from the orientation of the rollers for proper control of the coil end shifts (B) on the winding reel (4V-41) to avoid neglect before loading.

Wire guide group (4C). The wire guide assembly includes two semicircular opposed wire entry jaws (431) hinged horizontally on the sides (430) and controlled by a fast moving dynamic fluid cylinder (4311) at the end of the movement arm jaw (4310) articulated on the sides at the machine base (4301) and rotated outward and approached by a reaction arm (43101) operated by a fluid-operated base cylinder (43102).

In this way it is understood that while the opposite thread base (43102) sends out and approaches the wire entry jaws (431) its final movement is made, which is accurate and quick to engage and disengage the wire. , occurring with independence, speed, precision and fast control (4311) which on the other hand may prove the impossibility of this kind of performance by the approach and space-moving device apart with great excursion (43102).

This allows very high speed and good performance in its performance without the danger or risk of tangling or the need to reduce advanced yarn speed or the need to use speed adapters. The brief movement of interlocking and clearing is clearly visible in Figure 5.

Winding Central Group - Winding Reel (4A, Figure 7, 7a, 7B, 8) The central winding reel (41) is comprised of a closing and opening (AV) reel, Possible reel action to be closed and opened (AV): The possible to be closed and opened (AV) reel necessarily for the extraction of the coil (B) once it is completed occurs through four sectors with retractable petal edges (411 ) with a reaction arm (4111) driven by a connection (413) that moves axially by means of a dynamic fluid cylinder (4131-4132) operated by a dynamic fluid circuit (4133) with transmission at the carriage base (41330). ) on a non-rotating coaxial axis with respect to the rotational reel (AV). The advantage of this solution is very important for the compactness and simplicity of rotation guaranteed by connecting the rod end (4131) to the connection (413).

Variation of Outer Shape of Reel Mandrel (AV) The Reel Mandrel (AV) is composed of four sectors, notably four tongs (410) hinged to the base (4121) of a reel edge below the coil resting place (412). ).

At its top, the movable sectors of the reel chuck (410) are hinged (4112) to said axially movable connections (413).

In this way, the movable connections (413) are increased at the edges of upper petals (411) which are opened, notably to the reel axis and allowing the formation of the coil (B) during winding, and the reel mandrel sectors (410). ) being parallel and forming a cylinder (Figure 7).

When the coil is terminated in order to facilitate extraction, the movable internal connection (413) is withdrawn downwards operating simultaneously: - the edges of the upper petals of the reel closing upwards like a flower; - the core sectors reentering the top (410, Figure 7A) determining a conical shape with the size of the upper base being smaller than the lower base.

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

Cooling System The semicircular reel chuck or collet sectors (410) are internally drilled with tubes. The pipes or channels lead into a connector duct (41020) with a double inner coaxial duct (41021, 41022).

By this way the cooling of the reel is guaranteed.

In addition, the outer shape of said core clamps or sectors is corrugated by means of reciprocating longitudinal depressors (4101).

By this contact the surface of the reel mandrel (AV) with the coil (B) is reduced and air circulation through these longitudinal lowerers is facilitated. The reel (AV) alternates coaxially with the central axle by means of motorization known in the state of the art with connection by a chamfered path (40, 401-402).

Winding Cycle The winding of the bobbin begins by means of said opposite moving semicircular jaw devices (431) in association with the yarn introduction system (AB) for the first shift adhering to the side or base of the reel edge (AV). of winding machine.

This apparatus receives the wire (F) from a dispenser (2-3) while it is hermetically secured to the reel chuck (AV) and after priming the first turn, the coil forms an area to which it must be quickly released. To perform this procedure more efficiently, rapid movement of the ready displacement (short rotation 4310, Figure 5) is used. Subsequently, with other fast and slow rotational movements (4310-43102), the outwardly directed wire guide jaws are realized, leaving the approach space of said coil shift rollers free. (422).

In this way when the coil is stopped, the last turns are effectively secured until the intervention of the locking device (522) of the transfer (5), whose four jaws are rotated at 45 ° to tighten the coil (B) between said rollers ( 422).

Subsequently the rollers 422 move outward and the coil b still remains closed by the locking apparatus. At the same time the reel (AV) is also opened and then tightened and stretched closing the edges of the upper petals which are oriented upwards.

In this sense, the coil lock is also relieved internally and can easily be removed upwards by lifting the upright bar transfer arm (52) and pivoting to the rear for deposition of the connecting machine with the two opposite groups. of connection (6). At this point the cycle is repeated returning the priming of the wire guide jaws to the position adjacent to the reel chuck (AV) to receive a new wire (F) to be blown (Figure 4).
