Description

DESCRIPTION of the industrial invention

The present invention relates to the production of yarns by winding, ie the combined process of spinning and winding, ie winding.

The winding operation generally has a productivity? much more? high than that of spinning, as the yarn is spooled with speed? much more? higher than those with which it is spun. For this reason a small number of winding stations? able to process the yarn produced in a large number of spinning stations, for example of a ring spinning machine, which produce many spools of thread wound on tubes that are unraveled and rewound in a smaller number of larger packages after eliminating any defective or irregular sections from the wire.

The difference in productivity? between the two stages? such that the winder itself? able to absorb the yarns produced by pi? spinning machines and frequently also to work at the same time yarns of different types produced at the same time by different spinning machines connected to the winder by continuous transport systems.

The handling involved in the winding does not only concern the full cops supplied by the spinning to the winding and the empty tubes returned from the winding to the spinning to form new cops, but also a non-negligible number of irregular cops. Such irregular spools are generally tubes from which the wound yarn is not? been taken completely and from which the winding station is not? able to recover further yarn, for example why? Not ? able to grasp the key to resume its unraveling, with the means of which it? equipped with. The re-use of these irregular spools therefore requires special separate processing circuits for their exhaustion or for their unloading.

Before feeding the bobbins to the winding? it is necessary to prepare them with the end of the thread in a predetermined position, for example threaded into the tube on which? wrapped up. The winding station? cos? able to pick up the end of the bobbins on its own and start winding with an automatic procedure without the intervention of the operators.

Between the spinning wheel and the winder is there so? a considerable circulation of material to be handled and controlled: the empty tubes returned to the spinning machine to rewind them as new spools, the wound spools produced by the spinning machine to be prepared and fed to the winder. In the winding machines of updated conception each winding station? able to treat fifty and more? shuttles for now, cos? that the overall handling concerns thousands of pieces per hour.

For these reasons, the handling and normal management of the machines are entrusted to the pi? possible to automatic devices, the intervention of the operators being limited to supervision and malfunctions.

A technical solution for the handling of spools and tubes that has met with considerable favor, for example according to patents FR 1.571.158, JP-A-12128, DE 3.235.442 and 3.213.253, consists in transferring them on plate supports provided of a central vertical pin that holds them in an upright position and in moving the plate itself in the circulation between and within the machines themselves, even during the preparation and unwinding phase.

This arrangement allows the spools to be transferred and processed practically without touching them and without the thread wound on them getting dirty due to unwanted contact with parts of the machine. The vehicle constituted by the plate is also very useful for the simultaneous processing in the winding of more? lots of different yarns, why? the bobbins can be distinguished from each other on the basis of the plate that carries them and then directed towards the stations of the winder which are specifically intended for each of the batches being processed.

In the known art, the movement of the plates carrying the cops or the tubes? generally carried out by making the surface on which they rest move, for example conveyor belts for rectilinear motions and rotating discs for circular motions.

The management of the handling of the material in the winding machines is then even more? delicate and complex in the event that pi? batches are processed simultaneously.

The present invention relates to a process and a device for winding yarns into bobbins for the simultaneous processing of a plurality of yarns. of lots of yarn that provides for feeding, processing and handling d? full spools and exhausted spools with said plate supports.

How already? mentioned above, in the known art it is envisaged to identify the type of spool on the basis of the plate on which it is fed, for example as described in Italian patent application no. 49452A / 83 According to this solution, the winding machine has a set of plates of different conformation and the spools of the different batches are loaded on said different plates. This different conformation can? be made up of one or more? grooves on the cylindrical surface of the base of the plate or by metal magnetic ring inserts or bar codes which are the same for all the plates of a certain series of the machine equipment.

The discrimination of the spools is made solely on the basis of the plate that carries them and the spools carried by the same type of plate are therefore indistinguishable from each other. Discrimination occurs on the basis of a sensor which identifies the marking on the plate, discriminates it and gives a corresponding operating instruction for sorting. This type of approach to the problem involves dividing the winder, in advance and rigidly, into a plurality of? of separate sections which can be reached with appropriate deviation of the paths of the plates, in correspondence with doors that are opened or closed by the identification sensors. In the most? simple the paths are discriminated on the basis of a geometric constraint, for example they can be equipped with deviating guides with plates placed at the levels of the grooves and the selection is based on whether or not the levels of the grooves on the base disc of the plate and the plate coincide diverter. This kind of problem solving does not? free from significant drawbacks, such as for example the rigidity? of the subdivision of the winder in its sectors of different processing, the necessity? of a very large number of plates supplied with the machine, wear and inaccuracies due to mechanical selectors in contact.

According to a technical solution pi? recent, for example according to the Italian patent n? 1.246.225, it is envisaged to provide the plates or spool tubes with magnetic memory elements, such as electronic chips, on which the indication of the type of spool that is fed to them is loaded each time and then deleted. The selector elements of the machine operate on the basis of the information recorded on each of the plates which is erased and again recorded at each spool loading on it. Also this technical solution provides for dividing the winding machine, in advance and rigidly, into a plurality of products. of separate sections which can be reached with appropriate deviation of the paths of the plates in correspondence with accesses that are opened or closed according to the identification read on the plate. Each section of the winder is constituted as a winder independent of the other sections and which does not communicate with them. Also in this case the shuttles of each batch circulate indistinctly within their sector, once the deviators have directed them into it: a possible registration or reading error cannot? pi? be remedied.

Purpose of the present invention? that of realizing a device and a procedure for the simultaneous automatic winding of a plurality of of batches of yarn, free from the drawbacks of similar devices of the prior art.

In order to make the characteristics and advantages of the present invention more evident, it is hereinafter described with reference to a typical embodiment thereof illustrated in Figures 1 to 3 by way of example but not of limitation.

The identifying element of the material that circulates inside the machine? consisting of a plate for conveying the spools and tubes, which contains a memory chip - that is an integrated recordable and readable microcircuit - for coding, in which an identification code of the individual is recorded, in a permanent and non-modifiable way by the machine plate. This guarantee of non-modifiability? the identification coding of each plate is given, for example, by introducing in the chip program a "password" for any cancellation or new registration on it.

Each clay pigeon can? be, and in practice? In its path in the machine each target? cos? also distinguishable from the targets that carry the cops of its own game. The structure of the plate can? advantageously be provided with elastic elements for retaining and centering the spools and tubes according to the copending patent application n? MI96A125.

According to the diagram of Figure 1, the plate 1 carries the full spool 2 wound on the tube 3 and is made to travel on the plane 4. The chip 6 is inserted in a protected position in the base disk 5 of the plate, in which preferably? the identification code was recorded before its insertion in the plate. The identification of the plate is carried out with a detector 7 placed at a discrete distance with respect to the plate in transit and in correspondence with a portion of the support surface 4 made of non-ferromagnetic material.

In its essential lines the detector 7? consisting of an antenna emitting an electromagnetic pulse which excites the chip 6 to emit a response pulse corresponding to the encoding recorded on it and which discriminates each plate from the others. The signal with the encoding of the plate passed in correspondence with the detector 7 is transmitted with the line 8 to the unit? control of the machine for the required processing.

In Figure 2? illustrated the assembly diagram of the winding machine comprising both the part R of the actual winding and the part A containing its units? auxiliary feeding, preparation, recycling of the spools not exhausted and unloading of empty tubes, as well as? the services and the units? control of the machine. The winder? equipped with a device for moving and positioning the spools being processed making them slide by pushing on fixed support surfaces and following a path delimited by guides and deviators controlled according to the pending European patent applications n? 96200006, 96 200007 and 96 200024 to which reference should be made for more details about handling and processing. The remaining parts of the movement circuit of the plates carrying spools and tubes can be made with conveyor belts or with other movement means known in the art.

The circuit part 10 of the handling path? dedicated to the feeding of full cops to the winding stations in which a plurality of thrust members 11 circulating along a closed path carry the plates 1 with their spools 2 of the various batches, keeping them ready for the winding stations that require them. For simplicity? white spools and black spools have been indicated to indicate spools of different batches. The path (10) constitutes cos? the only path for feeding all the winding stations (12) for the various batches of yarn.

The winding stations 12 are indicated in broken lines and placed facing the return path of the spools of the circuit 10 and arranged above in correspondence with the passages 13 towards the path 14 for the return of the empty spools or for the recycling of the unused spools. Along these stations and in these passages, the cops are placed according to waiting stations, in which the cops are in reserve for the reeling, unwinding and unloading spool respectively, from which the exhausted cops are removed in path 14. In circuit 10 the spools are continuously in circulation and pass indistinctly in front of all the winding stations, since the winder is not divided into separate sections for the various batches.

In the realization of figure 2? was indicated as divided into two sections, the left one for the white spools and the right one for the black spools, in reality? such physical subdivision not? absolutely necessary. Each winding station 12? equipped with a diverter 15 which is activated, every time that its waiting station has delivered its plate with the full spool to the following unwinding station and yes? then freed, to intercept the target with the shuttle of the specific batch, to which it? been dedicated with a command sent through the unit? control of the winder as a setting for the working campaign. The winding stations 12 dedicated to the different batches can be divided in any way, for example by alternating them and dedicating the even stations to the white bobbins and the odd stations to the black bobbins. The division of the machine into sections or groups takes place solely on the basis of a logical assignment of belonging without barriers and physical separations, how? instead in the devices according to the known art.

This subdivision can? be modified also during the working campaign, for example when you want to dedicate a greater number of stations to one batch of yarn and a smaller number to the other batch. As described more? forward, this opportunity? it is very advantageous at the so-called end of the game.

Each winding station 12? connected with the unit? of government of the machine,? able to give and receive information and consequently recall any shuttle 2 of the totality? of spools that pass in front of it, choosing the type of spool that? been assigned and obviously to unload the targets with the spools exhausted. This can? take place, as well as depending on the situation in the various positions of the winding station, also taking into account particular logics of distribution of the bobbins within the machine, for example by favoring the stations that operate with higher speeds. linear, or the stations that first requested the replacement, or finally the stations that are more? close to complete the length of the bobbins and so? Street.

The logic type assignment allows you to create a machine system with the following characteristics:

- the number of definable groups of winding stations? limited by the number of stations of the machine: a winder made up of sixty stations could work up to sixty batches of different yarns at the same time;

- the number and location of the stations making up the various groups can be changed at any time, without any mechanical / electrical modification and in a time corresponding to the allocation in the unit? control unit supplied with the winder;

- Not ? Stations belonging to the same group must be adjacent.

The movement circuit of the spooler according to the invention is described starting from the loading stations of the bobbins on the plates without the tube coming from the unit. of the tubes 20.

Said unit? discharge of the tubes? consisting of an interception member of the plate that blocks its path on the conveyor belt and stops it, letting the conveyor belt slide under it, and of a gripper element that moves on a conveyor with vertical pitches, similar to that described in the patent EP-A-463.674 already? cited and in the name of the same applicant to transfer the spools of the spinning machine, which undermines the tubes, delivers them to the return transport line to the right of the spinning machine and not shown in the figure.

This operation is carried out only on the targets for which? been ascertained that the tube above? without thread, while the other targets are left to continue. A special guard photocell sensor device lets the plates start again only after having checked that their tube has been removed. On this occasion the reader 21 detects the name of the discharged plate and transmits it to the unit? machine steering; following this reading, the previous entry in the electronic coding table / batch of spool is deleted, which will come? renewed at the next stage of the machine circuit, consisting of the loading stations. If, on the other hand, the plate is presented with an unused package, the plate is not deprived of its tube, its registration is not canceled and it is allowed to pass through the loading stations towards the subsequent stations for preparing the packages.

Said loading stations 22 and 23, respectively for the type T (black) and S (white) spools indicated, but which could be in a much greater number for a greater number of batches of yarn to be processed at the same time, consist of members gripper grippers, which move on conveyors in vertical steps similar to those mentioned above, and lead the spools of their own batch to insert them on the plates that run along the path 24 constituted for example by a straight conveyor belt.

The insertion of the spools on the plate can? preferably take place in a single load segment, for example by delivering the spools of the two or more? games with conveyor pliers that tread the spools on their plate. In the loading segment defined by the loading stations 22 and 23, the empty plate in transit in the path 24 is stopped at the loading station, a spool is fitted to it on the respective peg, and in a station 25 inside the segment it is identified by the code reader 26 which detects the name of the loaded plate and transmits it to the unit? control of the machine, together with the identification of the type of spool according to which of the two stations 22 or 23 delivered the spool T or S respectively.

The information "the plate xxxx carries the spool of type S" forms the electronic table of the situation on the machine.

These pairs of data are in fact gradually transmitted to the unit? control unit of the machine to form an association table of the type

SPOOL TYPE PLATE CODE

from which ? It is possible to uniquely trace the type (or batch) of spool carried by each plate in the cycle. At each new plate / spool coupling the situation is updated and the table constitutes the main tool for distributing the spools to their winding processing stations.

To the table indicating the match of the shuttle? It is possible to combine other information, relating for example to:

material, color, length, spool type (geometry) ...,

- origin, results of the processes to which? been submitted, ...,

- destination, list of processes to which it must be subjected,

In the same way, any combination of the following cases can be handled simultaneously:

- different spools: for material, color and / or geometry, quality? ...,

- identical spools but with different attributes: full spool, discarded spool, partial spool ...,

spools equal but with different feed: spool ready for unwinding, spool to be prepared with end pick ...

The plate xxxx with the type S spool inserted continues on its way along the path 24 and is transported to the end preparation and search stations 30 and 31, which correspond to two alternative paths 32 and 33 respectively by means of a diverter, placed at the end of the path 24 and for simplicity? not shown in the figure, which operates on the basis of identifying which of the two stations 22 or 23 delivered the shuttle.

According to a preferred embodiment of the invention, each of such preparation stations? dedicated to a specific batch of yarn of the two being processed, why? the optimized preparation procedure could require different working parameters according to the characteristics of the yarn batches that are processed. The two alternative routes through the preparation stations 30 and 31 allow to create a certain reserve of plates already? provided with spools for the circuit 10 for feeding the winding.

The preparation stations 30 and 31 of the spools S and T are made to operate according to processes and devices for s? known from the art, for example according to the process described in patent application EP-A-463.695 in the name of the same applicant, to which one can? refer for more details. In its essential lines, it consists in the exploration of the foot and of the surface of the spools with suction nozzles for capturing the end, keeping the spool in counter-rotation with respect to the winding direction, in the subsequent exploration with a nail member with the spool rotating in the same direction of the winding, in the socket with a curved suction nozzle of the end cos? traced and detached, in its cut to size and insertion by suction into the inside of the tube. Typically the success of the operation? signaled by an appropriate sensor that signals that the end has been taken and d? consent to the continuation of the procedure.

The spool, after its successful preparation, then continues towards the winding machine with the path 32 'and 33', respectively with the type S and type T spools, to form the tail of the spools ready and awaiting loading at the winder R. In the event that the preparation is not successful, the bobbins involved are started on the parking path 34 of the bobbins waiting to be prepared by hand. This parking start is carried out with switches placed on paths 32 and 33 of the type per s? known and therefore not shown in the figure for simplicity.

At the end of each of the two paths 32 'and 33' on which there are the queues of spools ready waiting, there are two distributors 35 and 36, which are capable of alternative opening so as to be able to release only one spool at a time and of the batch requested at delivery station 37, into which a plate with shuttle is pushed by distributors 35 or 36.

The detail of Figure 3 illustrates the structure and operation of these plate distributors 35 and 36 with alternative opening. On the external side of the paths 32 'and 33' there are the two members 35 and 36 each consisting of a horizontal and crescent-shaped plate 101 and 102 with the concavity. facing these paths. The plates 101,102 are hinged on the vertical pins 103,104 and are capable of rotation in the horizontal plane to move into two alternative positions defined by the limit switches not indicated in the figure for simplicity: the rest position (solid line) in which the passage of the plates is locked, and the release position (dotted line) in which the first plate of the tail is left free.

Under the guides 105,106,107, which define the paths 32 'and 33',? placed a conveyor belt 110 which is kept in continuous movement according to the arrow c to bring the plates towards the circuit 10, to its loading position 37. The conveyor belt 110? made with a width 1, sufficient to carry out the movement in both paths 32 'and 33'.

A spring return 111,112 tends to hold the plates 101,102 in the rest position with solid line, while a pneumatic piston 113,114 with single effect? capable, when fed with pressurized fluid, to overcome the traction of the spring 111,112 and to make the plate 101,102 rotate according to the arrow a.

Distributor 35,36 operates as follows.

On the path 32 ', 33' the plates 1 'and 1 "of each of the two types of spool being processed are stopped in the queue, blocked by the interference of the end 115,116 of the plate 101,102 while the conveyor belt 110 runs under them according to the arrow c) The situation is the one shown in solid line

When a plate is to be released from the distributor 35,36, the piston 113,114 (either one or the other) is then fed with pressurized fluid, causing the plate 101,102 to rotate according to the arrow a, to move into the dotted configuration.

The two plates 1 'and 1 "of the queue on the path 32', 33 'for the two batches move according to the arrow c, dragged by the conveyor belt 110 below, according to the command sent by the central control unit of the machine , which affects one or the other batch alternately.

The plate 1 'proceeds freely towards the loading position 37, but the following plate 1 "moves only up to its dotted position and therefore locks due to the effect of the interference with the end 117,118 of the plate 101,102.

When the pressure in the piston 113,114 is released, the return of the spring 111,112 prevails and there is the reverse rotation of the plate 101,102 according to the arrow b. The plate 1 "then moves from the hatched position to the solid line position 1 ', previously occupied by the plate just released.

From said loading position a shuttle is delivered with the relative plate, according to the logic set for the management of deliveries in the unit. control of the machine. For example, a spool of the same lot as that of the last spool delivered to the winding stations 12 is delivered to circuit 10, or of that of the last plate from which in station 20? the empty tube has been removed. In general, except for the transitional periods at the beginning and at the end of the batch, the numerical ratio between the cops of the various batches being worked in the circuit 10 of the section R of the machine is kept substantially constant.

For this purpose, a sensor 38 is installed in the circuit 10 and immediately upstream of the delivery station 37, for example a photocell sensor, which signals the arrival of an empty position of the circuit, or of a thrust member 11. without plate, and commands the actuation of the distributors 35 or 36, or causes their command, according to the described management logic.

The shuttles cos? loaded into the handling circuit 10, they are kept in continuous circulation and pass in front of all the winding stations 12 of the machine, gradually replenishing the empty positions of the circuit 10 with new spools to keep them occupied as much as possible.

Each of said stations 12? equipped with a code reader 39 positioned to detect the name of the plate arriving in front of its winding station (or head). Such readers 39, cos? like the other code readers present in the machine, are they connected to the unit? control of the winder, for example with a serial line, and with it they exchange information in real time, receiving consent to operate.

In the winding process, each winding head 12 in which the waiting station? without spool waiting, having delivered it to the unraveling station - in the realization of figure 2 the second and last heads are without it going from left to right - keeps in activity? its reader 39 to "read" the identification codes of the targets in transit, consults, through the unit? of government, the plate / spool association table described more? above and, if the incoming target brings a shuttle from the game to which the head in question? dedicated, receives the consent to activate the return device of this spool with its plate diverter 15.

According to a preferred embodiment of the device and of the method according to the invention, each winding head thus? like the other units? of the machine can read, add or modify information on the association table of the spools transported to the conveyor plates.

Inside the winding stations 12, the handling of the bobbins with the relative plates between the waiting, unwinding and unloading stations can? advantageously take place with the device described in the cited European patent application n? 96 200024 in the name of the same applicant, to which reference should be made for more details regarding handling and processing in the winding station.

At the exit from the winding section R, the conveyor 14 carries the exhausted cops towards the selection device 51 which serves to recognize the cops rejected by the winding heads due to the end not being picked up, the half cops and dirty tubes or finally the clean tubes.

Such a device? known from the art and consists, for example, of a mechanical feeler member which touches the surface of the tube and which, if there is a residual winding of yarn around it, is stopped at a certain distance or at a certain height, such as example in the Italian patent application n? 491441A / 83 in the name of Murata.

On the basis of the measurements of the device 51, the diverter 52 diverts the clean tubes and the spools still to be unraveled on the path 53, while the dirty bottoms and tubes - that is to say those tubes with a winding residue that is no longer convenient. unravel - are started along the path 54. A tube-cleaning device is placed along the path 54. known from the art and consists, for example, of a pick-up of the tube that temporarily removes it from its plate, takes it to a cutter-like cutting member that explores a generatrix of the truncated cone surface of the tube, cutting the residual winding of yarn and repositioning it then on the plate.

The paths 34, 53 and 54 meet with the main feed path 24, with the interposition of selective and alternative stop and start devices 56, 57 and 58, which respectively lead towards the device 20 or the cops to be recycled and the clean tubes of the path 53, or the tubes cleaned in the path 54 by the device 55, or finally the spools of the path 34 which have been worked by hand by the workers. The procedure of starting one plate at a time from the queues of plates waiting on these paths is managed by the unit? of government based on the queue management logic that the? been charged.

The structure and operation of the devices 56,57,58 are analogous to what has been described, again by way of example but not of limitation, for the devices 35 and 36 for delivering the plates to the circuit 10, in position 37.

The plates started on the path 24 by one of the three paths described meet a selector device 60 similar to the device 51 which recognizes on the plate in the position 61 the spools to be allowed to pass in order to return to the cycle for the use of the yarn wound on them and distinguishes them from the empty tubes to be undermined with the device 20 which follows in the circuit.

One of the characteristic advantages of the device and of the process of the present invention, due to the flexibility? which the invention allows and which distinguishes it from the known art, occurs on the occasion of the batch change, that is to say in the transitory phase in which one batch of yarn is about to be finished and another is put into operation.

On that occasion, the possibility? to modify the distribution of the winding heads between the two batches, without mechanical or electrical modifications but only by giving an appropriate instruction to the unit? control of the machine, it allows to remove from the processing of the batch that is about to finish, for example of the spools S, the winding heads that have reached the length established for the bobbin and to allocate them gradually to work on a different batch, which can ? be for example the match T gi? being processed in the other winding heads or a new batch V, U .... Can you cos? reserve the remaining spools S to complete the not yet completed packages on the remaining winding heads still working on batch S. In this way the end of batch S does not d? resulting in incomplete packages, the change of processing takes place gradually and without downtime as there are no rigid subdivisions in machine sectors.
