Description

This invention relates to a winding apparatus according to the pre-characterized part of the main claim.

This apparatus is particularly intended, if not exclusively, to be placed on the lower level of laminating apparatus, wires, strips or tapes, in which instead of the rotary cutting of the laminated material it is now wound into coils.

In the different systems present in the foregoing it is known for winding coils of laminated material and also yarn, for example originating from other apparatus, in a continuous path citing as an example: US-A-3,796,389 discloses an apparatus for strip winding placed on a feed line with a split system alternating winding machines in the winding operation.

A similar apparatus is disclosed in DE-A-4035193 where substantially a rotary cutter blade and a cracking system is provided without stopping the advance of the yarn in either winding machine, so that while winding is conducted In one machine, it is possible to proceed with the extraction of the coil in another.

Another similar apparatus is explained by EP1126933 in which a hand-held device is associated with each winding machine to axially withdraw the coil from the stopped winding machine and transfer it by evacuation while the other is being wound. Followed by the above JP06091720 {see Japanese Patent Summary Vol. 18, No. 354 (M-1632), July 5, 1994 (1994-07-05) - & JP06091720A (Mitsubishi: KK), April 5, 1994 (05.04.1994), In this disclosure exclusive M1, M2 motors are provided for the respective coils 5,6 to continue manufacturing a molded product B at the same time as the work to replace the coils 5,6. Roller arrangement 54a, 54b, prescribing the posture and shape of the molded product B are provided for the loading end of a guide arm 42 near the coils 5,6 to be moved in the lateral direction and the radius direction of the coils ( winding coils). Each winding spool having an outer flange made with radial arms (27) hinged to the winding spool mandrel (26) to be rotated extremely close to the axial direction to allow the spool to be extracted.

Known solutions have been operating at speed limits, and even more so are structurally complex and expensive. The winding process may involve stopping due to embarrassment and also because the coil handling and storage arrangements are impractical making the process completely slow.

The machines are embarrassing.

Thus one or more disadvantages and limitations are present in both systems.

In particular the solution of patent EP 1126933 is very complex and particularly ineffective due to the limited speed of the reel opening and closing system that occurs with a system in the form of a signaling opening lid, with all the resulting disadvantages. The complexity of these latter solutions derives further from the capture and movement of the coil system pulled by means of base guide rails, pulleys and the like. All of these configurations make the system very complex, disadvantageous and difficult to access and maintain. In conclusion it is a fallible, unreliable system. The speed of operation is further limited due to the complexity of the system structure for wire entry orientation and coil control after forming to be caught. The purpose of is to avoid the above-mentioned damage, to improve the performance of the apparatus and to improve the quality and / or reduce the costs of the treated material. The winding apparatus according to the present invention is embodied according to the features of the main claim.

The features of the subclaims relate particularly to advantageous solutions.

The advantages achieved achieve the pre-set objectives, and in particular allow a highly functional performance to be achieved, and even more allow a qualitatively good product to be obtained at a reduced production cost.

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

The features of the invention and other embodiments will be better understood with reference to the accompanying figures which are to be interpreted by way of example and not limitation, in which: Figure 1 is a schematic side elevational view of the winding apparatus applied to the end portion of a laminator line during the winding phase or winding in a first winding machine of two adjacent coordinate winding machines, which is supplied by a offset with an associated shear rotary cutter. Figure 1A represents the winding phase. deposit the coil at the docking station. Fig. 2 is a top view of the apparatus of Fig. 1 in which two adjacent winding machines are views associated with a transfer beacon, primarily with a column with a rotating arm projecting to extract the coils either from the winding machines. or unloading said coils at a mooring, transfer and reserve station of Figure 2A.

Figures 3A and 3B show, in an elevated side view, transfer bar as in the previous figures, respectively without coil, and with coil lowered and raised for transfer by means of rotation. Figure 3C is a plan view of the four collet coil capture device placed at the lower end of the transfer bar device arm portal.

Figures 4 and 4A respectively represent a side elevational view and a plan view of the winding machine from the feed side of the wire to be wound (AB) with the pair of wire guide tongs around the wire reel. to allow the thread to be threaded automatically shifted upwards from a slotted rotating blade (4C-2, 3) while the pair of rollers holding the coil compact at the end of the winding is rotated upwards from the winder ( 4B-422). Figure 5 is a view of the phase immediately following that of which the thread was threaded starting its winding (F), with the opposing wire guide clamps (4C-431) immediately raised with a small disengagement movement from the previous guiding position. the wire, this movement is very fast since it is not integrated within a full release mechanism that happens in a subsequent phase.

Figures 6 and 6A represent a view of the same device as in the previous figures, but in which the opposing wire guide tweezers are completely replaced by rotation in a different joint, sending away the winder (AV) while the two pairs Opposite rollers (422) are rotated nearby against the yarn bobbin which is formed in rotation (B). Figure 7 is an enlarged view of the constructive details of the winding reel (reel) for forming the coil in partial axial section to illustrate the respective movement of the mechanism and the cooling device. Said reel or reel being in position winding Figure 7A is a view of the winder (AV) as in the previous figure, in which in the partial axial section, the movement of the mechanism is still visible, and is subsequently transformed from a closed reel into a tapered reel (410) with the upper flange of the reel (411) rotated upwards mainly in the axial direction and outwards to allow axial extraction of said coil (B). Figure 7B is a plan view of the reel spindle sectors, which are a total of four, forming in a movable path the winding reel mainly the core of the winding reel, with a dashed view of the respective internal holes, these channels are for chilled water circulation and thus for the heat dispersion generated by the introduction of the coiled hot wire to the coil winding, along with the special corrugated outer shape of said mandrel claws / sectors to minimize contact with the wire and allow optimum dispersion of the caior by means of ventilation. Figure 8 is a front view of a reel claw (410) with a view of the respective internal channeling of the back and forth coils (4102) for cooling. Hereinafter the present invention will be fully understood in accordance with the exemplary and non-limiting description of the accompanying drawings.

As revealed in the previous figures, the winding apparatus (see figures 1-1 A, 2-2A) includes a known type split or cracking system with a rotary shearer, schematic with (1) that diverts the wire to two lines. alternatively at one or the other (2) towards one of the adjacent winding machines or towards the other (4) respectively, aiming at the suitable wire guide means of known types (3) for the winding spool (B) .

While a coil forms in a winding machine, in the adjacent winding machine that is stopped, the complete pickup of the bobbin is conducted with a transfer (5 ', ... 521).

Coil Transfer (5, Figures 1. 1 A, 2, 2, 2A, 3B, 3A, 3B, 30 The Coil Transfer (5 '..... 521) of Figures 1, 1A is of the portal type, principally with a column (51), with a signaling type rotary arm (52-510) whose end (521) drives a clamp opening device with a pair of opposite crossed clamps or jaws (522) for axial pickup and extraction of the coil (B) from the winding machine (AV) of the respective winding device (4, 4a), to transfer it (Figure 2) from the winding machine stop to a tie-down station by means of two machines already known by the state of the art of opposing binding or mooring machines (6) .Figure 2A being further provided with the transfer of the coil to the respective storage of tied coils (B1) .The transfer bar is thus provided with the portal type and its rotating arm (52) can be raised and lowered by means of a dynamic fluid piston (520) to capture and drive deposition, while rotation is ensured by a respective motor / motor ratio (510) at the base of the column over a respective thrust block (5101). The lifting and lowering arm (52) being secured by the folded plate guide (520) with opposing guide roller pairs (5201) operating in a sliding path over the double T-section column. Pickup of coils is facilitated by the device self-centering four-clamp stapling device over the coil (B), opening and closing by means of the respective opening and closing fluid operated cylinders (5220).

It is thus understood that the transfer movement is very fast and has a wide opening of air, so that it does not overload or prevent adjacent areas, while still allowing a better compactness of the apparatus. Moreover, this type of movement is manifestly very simple and very reliable with very low maintenance.

Winding Groups (4, 4A, 4B, 4C, Fig, 4, 4A, 5, 6.6A) The two winding groups are identical and adjacent with a wire take-up reel (F) having an openable reel ( AV) with a vertical axis.

Each group includes, in addition to the central winder (AV-41), two opposite coil compaction devices (4B) in pairs of rolls (422) and two self-introducing wire guide jaws to automatically guide the wire to the winding start (4C).

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

Opposite Roller Compaction Devices (4B).

They include two respective hinged devices (42), placed on either side of the take-up spool (AV) with respect to the yarn feed line that laterally adjusts into the spool (AB).

The rollers are mounted on a pivot arm (421) which bends relative to the base of the frame (420) and is operated in rotation from a distanced position (figure 4) to a position against the coil (B) of figure 6 The movement occurs by means of the fluid operated cylinder (4212) on a reaction inducing arm (4210).

Being a pair of said rollers (422, see figure 6A) mounted on a parallelogram (4222) in the pairs of opposite arms which in turn are mounted on the roller support (4220) and moved elastically under pressure by the respective means with the dynamic fluid cylinder (4221).

Thus, the movement is simple and reliable and the orientation of the rollers is invariably guaranteed to be unchanged providing proper control of the termination of the coil turn (B) in the winder (4V-41) avoiding the previous pickup inactivity.

Wire Guide Group (4C) The wire guide group includes two opposing guide jaws that allow for semicircular wire entry (431) horizontally hinged to the sides (430) and controlled by a rapidly moving dynamic fluid cylinder (4311). ) at the jaw end of the arm (4310) hinged to the sides of the machine base (4301) and rotated away and approached by a fluid-driven cylinder-operated throwing arm (43101) (43102).

Thus it is understood that while with opposite cylinders which are fluid-based operated (43102) the throwing and approaching of the jaws that drive the introduction of the wire (431) is conducted, their final movements being precise and quick to engage and disengage the wire with independence, short precision and fast action (4311) which would otherwise prove impossible with this type of performance by approaching and spacing the moving device with the wide excursion (43102) Thus, the above, It allows for extremely high speed and good performance which is achieved without the danger of embarrassment or the need to reduce the advanced yarn speed or the need to use the speed adapting to the loops.

The short engaging and disengaging movements are visibly clear in figure 5.

Central Winding Group - Winding Coil Í4A, Fiq. 7, 7A, 7B, 8) The central winding group comprises the central winding coil (41) with the closable or open (AV) coil. The closing action and opening of coil (AV);

Once the opening and closing of the coil (AV) required for roll extraction (B) has been completed, it occurs through four sectors of rotating flange petals (411) with an inductor arm (4111) driven by a connection ( 413) which moves axially by means of a dynamic fluid cylinder (4131-4132) operated by a dynamic fluid circuit (4133) with transmission to the coil base (41330) about a non-rotating coaxial axis with respect to the rotary coil (AV). The advantage of this solution is very important for the compactness and simplicity of rotation guaranteed by the end of the connecting rod (4131) with respect to the connection (413).

External Coil (AV) Format Variation The Coil (AV) Mandrel is comprised of four sectors primarily four claws (410) hinged to the base (4121) of a lower roll rest coil flange (412).

Over the top, the movable sectors of the coil mandrel (410) are hinged (4112) to said axially movable connection (413).

In this way, when the movable connection (413) is lifted, the overturning upper petals (411) are opened, mainly orthogonally with respect to the coil axes allowing the formation of the coil (B) during winding, and the spindle sectors of the coil (410) are parallel and form a cylinder (figure 7).

To allow easy coil extraction when terminated, a movable internal connection (413) is withdrawn from underneath while simultaneously operating: - the upper edge overturning petals of the reel that closes upward like a flower; - the top-re-entering core sectors (410, Figure 7A) determining a conical shape with the upper base size being smaller than the lower base.

In this way, the extraction of the coil (B) is possible and facilitated by the clamps of the clamp device (522).

Cooling System The semicircular shaped reel chuck sectors or jaws (410) are internally drilled with channels (4102). The channels carry from a connector duct (41020) to an internal duct with a dual coaxial channel (41021, 41022).

Thus the cooling of the reel reel is guaranteed.

Moreover, the outer core shape of said claws or sectors is corrugated by a tangle of longitudinally alternating wires (4101).

This reduces the contact of the surface of the reel mandrel (AV) with the spool (B) facilitating an air circulation through them a tangle of longitudinal wires. The coil (AV) rotates coaxially towards the center axis by known types of motorization with connection to a beveled type drive (40, 401-402) Winding Cycle The beginning of the winding of the roll occurs by means of said winding device. semicircular opposing jaws (431) in association with the yarn introduction system (AB) for the first clamping loop back to the side or to the base coil (AV) flange of the winding machine.

This device receives the wire (F) from the distributor (2-3) while it is firmly fitted to the coil mandrel (AV) and then for the first turn priming, the coil forming an area should be quickly released. To do this with maximum efficiency, a fast-moving rapid movement is used (short rotation 4310, figure 5).

Subsequently, with other slower and wider rotational movements (4310-43102) the wire guide jaws are driven away, leaving room for the approach of said last turn control rollers (422).

In this way when the coil stops on its last turn it is kept closed until the stapling device (522) of the transfer (5) intervenes so that the four jaws are turned 45 ° to staple the coil (B) between the said rollers (422).

Subsequently the rollers 422 move away and the coil B still remains closed by the stapling device. At the same time the reel (AV) is also opened by squeezing and closing the upwardly oriented upper petals of the upturn.

In this way, the closed spool is also internally relaxed and can easily be lifted upwards by lifting the arm (52) of the transfer bar (5) and can be rotated backward for deposition in the joining machine with 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 the reel chuck (AV) to receive a new wire (F) to be wound (figure 4).
