Definitions
- the present invention relates to a device for feeding types of pirns different in thread count, colour or composition to a plurality of winding stations, according to the preamble of claim 1.
- Pirns which are formed by a spinning frame, in particular a ring spinning frame, are subsequently unwound, and the thread is rewound on rigid cones, to produce cones having suitable shape and dimensions for the following processing steps, such as: knitting, loom feeding, warping, dyeing, or the like.
- An automatic coner machine prearranged for the rewinding operation shows a working front constituted by a considerable number of winding stations positioned closely approached side-by-side to each other.
- the thread drawn from a full pirn in feeding step, and fed to a corresponding winding stations is wound in cross-turns mode on a cone made revolve at a high speed by a drive drum, and during such transfer, possible faulty portions of the thread are removed.
- the whole winding front normally winds one type of thread.
- the pirns belonging to one single thread batch, can be randomly red, without any need for establishing a whatsoever relationship between the winding stations and the pirns to be fed to them.
- specific threads have to be respectively fed to specific winding stations, without mixing the fed pirns.
- coner machines are provided, each taking up more thread types. This makes it possible to optimize the usage rate of the winding stations, with said winding stations being advantageously grouped in sectors, whose extensions are related to the amounts, and to the characteristics of the individual thread batches which are simultaneously processed. It is advantageous as well to be able to operate by taking up two different thread types at the batch-end-change time.
- coner machines have been known in the art, which are equipped with a set of frontally predisposed storage units, a storage unit per each winding station, to contain the pirns which must be processed.
- the filling of the storage units is carried out by an attending workman.
- arrangements have already become known, wherein the pirns are fed and charged to the storage units by means of a conveyor tape. From said storage units, the pirns are transferred to the winding stations.
- Conveyance arrangements are also known, wherein the pirns are received inside trays fastened onto a conveyor belt which runs along a closed-loop path, along the whole working front.
- the working front of an individual automatic coner machine usually winds one thread type.
- only one type of pirn is fed to the individual coner machine, which can take up, on all of its winding positions, one type of pirn thread each time.
- a plurality of coner machines In order to re-wind a plurality of pirn thread types, which are different in count, colour or composition, a plurality of coner machines have to be used, wherein each of said coner machines winds one thread type, or, when on an individual coner machine a plurality of thread pirn types have to be wound, a different thread type will be wound after the end of the winding of a particular, previously fed thread type.
- said above described systems are not suitable for simultaneously supplying and feeding different types of threads, which are generally in the form of small-size batches, along an individual winding front.
- a pirn feeding device of the type defined in the preamble of claim 1, wherein the mechanical element is provided with a cam element and is fixed on each tray in one of four different angular positions.
- the cam element is provided for engaging actuating pins associated to delivery tubes for the pirns arranged below the trays at each winding station.
- Said pins are arranged according to four different angular directions so that the pins are selectively engaged only by the cams which are arranged according to a corresponding angular direction and are associated to trays transporting the type of pirns specific for the winding unit to which the pins are associated.
- each type of pirn must be housed in a specific tray, prearranged therefor.
- the conveyor constantly conveys a fixed sequence of pirn types and when the various winding stations operate at different production rates, as is often the case, an oversupply of one type of pirn and an undersupply of another needed type of pirn may occur.
- the present invention aims at the purpose of providing a solution capable of overcoming such drawbacks by a device wherein an automatic coner machine can simultaneously take up a plurality of different thread types belonging to batches different in count, colour or composition, according to the actual requests of the individual winding stations without any fixed sequence of the types of pirns fed to the machine.
- the present invention therefore, substantially consists of a conveyor device equipped with conveyor trays, which are different from one another in the position on them of a witness element, having a lever shape, or a pin shape, or similar shapes, which certifies the type of thread taken up on the pirn carried by the tray.
- a witness element having a lever shape, or a pin shape, or similar shapes, which certifies the type of thread taken up on the pirn carried by the tray.
- Each tray houses the individual pirn coming from the preparation station.
- Said preparation station makes it possible to search for, extract and position, in the desired form, the end of the thread contained on the pirns. These latter, after being prepared for undergoing the unwinding, are transferred into their respective housing trays, which are conveyed, in continuous, along the working front, to the winding stations.
- the device of the invention in no way alters the operating system and the equipment pieces composing the automatic coner machine, so that the traditional winding machine will be not described, but only reference to those parts thereof, which concern and clarify the present invention, will be made, and precisely reference will be made to the continuous belt or chain conveyor system, on which the trays housing the pirns are fastened, as well as to the chutes along which said pirns move from up downwards by gravity, in order to prepare them on their corresponding receiving pins.
- the station for the search for, and the charging, of the pirns to be unwound will not be described: it is in fact already per se known in many structural forms, and a detailed description thereof is not necessary. To the end of the present invention, it is important that such station for pirn searching for, and charging should be equipped with lever systems, also already known from the prior art, to carry out the transfer of the prepared pirns into the trays of the conveyor system which makes it possible to automatically feed the pirns to the winding stations.
- a valuable advantage of the device of the present invention is its suitability for being applied both on working fronts of already existing machines, and on working fronts of the machines under way of assemblage.

Description
- The present invention relates to a device for feeding types of pirns different in thread count, colour or composition to a plurality of winding stations, according to the preamble of claim 1.
- Pirns, which are formed by a spinning frame, in particular a ring spinning frame, are subsequently unwound, and the thread is rewound on rigid cones, to produce cones having suitable shape and dimensions for the following processing steps, such as: knitting, loom feeding, warping, dyeing, or the like.
- An automatic coner machine prearranged for the rewinding operation shows a working front constituted by a considerable number of winding stations positioned closely approached side-by-side to each other.
- The thread drawn from a full pirn in feeding step, and fed to a corresponding winding stations is wound in cross-turns mode on a cone made revolve at a high speed by a drive drum, and during such transfer, possible faulty portions of the thread are removed.
- When all of the thread of the pirn has been wound on the cone, a subsequent pirn is fed again, and the end of the thread on the cone side, as well as the thread end on the side of the new pirn are knotted to each other, to continue the winding operation, so that a cone is formed, which is completely filled with threads coming from a large number of pirns filled with the same thread type.
- On such an automatic coner machine, the whole winding front normally winds one type of thread. Thus, in this case, only one type of pirn is used, and the pirns, belonging to one single thread batch, can be randomly red, without any need for establishing a whatsoever relationship between the winding stations and the pirns to be fed to them. However, when different thread types are wound up by an individual winding front of the individual automatic coner machine, specific threads have to be respectively fed to specific winding stations, without mixing the fed pirns.
- In this case, coner machines are provided, each taking up more thread types. This makes it possible to optimize the usage rate of the winding stations, with said winding stations being advantageously grouped in sectors, whose extensions are related to the amounts, and to the characteristics of the individual thread batches which are simultaneously processed. It is advantageous as well to be able to operate by taking up two different thread types at the batch-end-change time.
- For example, for a long time, coner machines have been known in the art, which are equipped with a set of frontally predisposed storage units, a storage unit per each winding station, to contain the pirns which must be processed. The filling of the storage units is carried out by an attending workman. In order to eliminate such a manual operation, arrangements have already become known, wherein the pirns are fed and charged to the storage units by means of a conveyor tape. From said storage units, the pirns are transferred to the winding stations. Conveyance arrangements are also known, wherein the pirns are received inside trays fastened onto a conveyor belt which runs along a closed-loop path, along the whole working front.
- In some structural solutions, the working front of an individual automatic coner machine usually winds one thread type. Thus, in this case, only one type of pirn is fed to the individual coner machine, which can take up, on all of its winding positions, one type of pirn thread each time.
- In order to re-wind a plurality of pirn thread types, which are different in count, colour or composition, a plurality of coner machines have to be used, wherein each of said coner machines winds one thread type, or, when on an individual coner machine a plurality of thread pirn types have to be wound, a different thread type will be wound after the end of the winding of a particular, previously fed thread type. In other words, said above described systems are not suitable for simultaneously supplying and feeding different types of threads, which are generally in the form of small-size batches, along an individual winding front.
- On the other hand, it is also known, in some structural solutions, and, e.g., from JP - A - 143,565/83, to equip an automatic coner machine with conveyance routes which occupy a rather large surface area of the floor adjacent the coner machine. In such a structural solution, the conveyance routes extend on a floor surface area which is often larger than the surface area of the base of the same coner machine. Furthermore, such a solution is also disadvantageous from the view point of the increase in complexity of the base structure which becomes, due to its location at the floor level, an area wherein the building up occurs of dust, large amounts of which are always present in a textile factory.
- The build-up of dust causes the damaging to start of the drive mechanisms moving the pirn-holder plates and of the various running components of the machinery, due to the effect of an excess of dirt which is generated by the continuous building-up of said dust. All the above is furthermore a factor which considerably increases the contamination of the threads of the pirns, which are moved without being protected by any protecting trays.
- From US-A-3 774 859 there is known a pirn feeding device of the type defined in the preamble of claim 1, wherein the mechanical element is provided with a cam element and is fixed on each tray in one of four different angular positions. The cam element is provided for engaging actuating pins associated to delivery tubes for the pirns arranged below the trays at each winding station. Said pins are arranged according to four different angular directions so that the pins are selectively engaged only by the cams which are arranged according to a corresponding angular direction and are associated to trays transporting the type of pirns specific for the winding unit to which the pins are associated. In this known device, therefore, each type of pirn must be housed in a specific tray, prearranged therefor. This means that the conveyor constantly conveys a fixed sequence of pirn types and when the various winding stations operate at different production rates, as is often the case, an oversupply of one type of pirn and an undersupply of another needed type of pirn may occur. This may result in a substantial production slowdown of the coner machine because needed types of pirns may become available only with more or less delay.On considering the above, as well as analogous drawbacks and disadvantages affecting the known solutions, the present invention aims at the purpose of providing a solution capable of overcoming such drawbacks by a device wherein an automatic coner machine can simultaneously take up a plurality of different thread types belonging to batches different in count, colour or composition, according to the actual requests of the individual winding stations without any fixed sequence of the types of pirns fed to the machine.
- This purpose is achieved by a device as claimed in claim 1.
- The present invention, therefore, substantially consists of a conveyor device equipped with conveyor trays, which are different from one another in the position on them of a witness element, having a lever shape, or a pin shape, or similar shapes, which certifies the type of thread taken up on the pirn carried by the tray. Each tray houses the individual pirn coming from the preparation station. Said preparation station makes it possible to search for, extract and position, in the desired form, the end of the thread contained on the pirns. These latter, after being prepared for undergoing the unwinding, are transferred into their respective housing trays, which are conveyed, in continuous, along the working front, to the winding stations. Incidentally, it is known in the art to prepare the thread end, e.g., on the top of the pirn tube, or inside the hole of the tube of the same pirn; the device, or the station, for the timed search for the end of the thread of the pirns, in order to prepare them for the subsequent unwinding is known as well, and also known are lever systems for transferring the pirns from said pirn end search station to a tray on a conveyor.
- The device of the invention in no way alters the operating system and the equipment pieces composing the automatic coner machine, so that the traditional winding machine will be not described, but only reference to those parts thereof, which concern and clarify the present invention, will be made, and precisely reference will be made to the continuous belt or chain conveyor system, on which the trays housing the pirns are fastened, as well as to the chutes along which said pirns move from up downwards by gravity, in order to prepare them on their corresponding receiving pins.
- Furthermore, the station for the search for, and the charging, of the pirns to be unwound, will not be described: it is in fact already per se known in many structural forms, and a detailed description thereof is not necessary. To the end of the present invention, it is important that such station for pirn searching for, and charging should be equipped with lever systems, also already known from the prior art, to carry out the transfer of the prepared pirns into the trays of the conveyor system which makes it possible to automatically feed the pirns to the winding stations.
- A valuable advantage of the device of the present invention is its suitability for being applied both on working fronts of already existing machines, and on working fronts of the machines under way of assemblage.
- Futhermore, in no way operators attending the device, which operates in a completely automatic way, are necessary.
- The preferred form of practical embodiment herein illustrated is neither binding nor limitative as to the mutual position of the components and as to the consequent simplifications which could derive from it; said solution is herein illustrated in order to exemplify the device of the present invention in its entirety, precisely resorting to a preferential form of practical embodiment.

pirn 16, the station 8 predisposes it and charges it, by a technique known in the prior art, into theproper conveyance tray 2 and simultaneously, by detecting and memorizing the type of pirn, 16A or 16B or 16C, which it is charging, the station 8 predisposes thediscriminator element 47 in the A or B or C position namely with the end of thearm 56 inposition 64A or 64B or 64C and the end of thearm 52 inposition holder conveyor belt 26 continuously transfers the spinningpirns 16 along the winding front of the automatic coner machine. - The automatic coner machine is subdivided into winding
sectors movable striker element 72 inposition 72 A or 72B or 72C, located in height (see Figure 2) in accordance with the type ofpirn - Normally, the
mechanical striker element 72 is in its rearwards-moved position. When a winding station ends the unwinding of a spinningpirn 16, the pirn-holder plate 28 revolves through one step, putting under unwinding the pirn previously charged in reserve position on areceiver pin 30, and makes themechanical striker element 72 come out, with a substantially horizontal shifting, to reach its position of mechanical interference with the correspondingrelease arm 52 inposition - Said
release arm 52, running together with theconveyance tray 2 housing thepirn 16, yields by rotating during the interference step, around thevertical hinge 68 of thediscriminator element 47, simultaneously causing the shifting, from its locking position, of thewing 50 which in its turn releases themovable bottom plate 36 of theconveyance tray 2. The spinningpirn 16, of the type as determined by the position of the above-said interference elements, by being free from its bottom support, starts sliding by gravity along therigid chute 34, running along the direction indicated by thearrow 35, to come to slip, after running along the self-centeringguide chute 32, on thereceiver pin 30. Said spinningpirn 16 goes to constitute the reserve in the pirn-holder plate 28. Themechanical striker element 72 of the associated winding station is made re-enter through a substantially horizontal shifting by using means per se known, and therelease arm 52 places itself, or remains placed, in a position of non-interference with possible subsequent striker elements positioned inposition 72A or 72B or 72C at other winding stations which require a spinningpirn 16. The conveyance tray returns empty back to the station 8. - Along the path length preceding the area wherein the spinning
pirns 16 are charged to theconveyance trays 2, themovable bottom plate 36 of the tray comes back to its closed position, so driven by suitable driving means, not shown in the Figures, because they are per se known. Thediscriminator element 47 during the step of pirn charging to the tray, by pivotably actuating thediscriminator arm 56 causes therelease arm 52 to assumeposition discriminator element 47 about thehinge 66 positions theball 58 inside one of thehollows 62, with a stable and safe position of thediscriminator element 47 and of therelease arm 52 during their movement being obtained thanks to the urging by thespring 60. Said spinning pirn, delivered to, and housed inside, theconveyance tray 2, runs along the winding front, ready to be conveyed on areceiver pin 30, to feed a pirn-holder plate 28 of a whatever winding unit belonging to a windingsector - In case from the
conveyance trays 2 the pirn is not drawn, when this latter runs before the station 8, suitable optical detecting means or sensors, already known per se, provided in the area which precedes the area concerned by the pirn charging operation, recognize the presence of thepirn 16 in theconveyance tray 2, and inhibit the actuation of the cycle of pirn charging to the above saidtray 2. The charging cycle will be actuated at the passage of a subsequentempty tray 2 running before the pirn preparation station 8. - One should observe that although the invention has been disclosed by referring to the practical embodiment wherein the automatic coner machine is subdivided into three winding sectors, i.e., the A, B, C sectors, the number of such winding sectors can anyway be increased to four or more, by positioning the discriminator and detector elements in a plurality of positions, subtantially a position per each individual winding sector.
- A preferred solution has been herein disclosed with some variants thereof, but other solutions are anyway possible.
- Thus, positions of the operative lever systems can be varied; a tray-holder conveyor belt can be used, which is provided with an intermittent motion; shapes and dimensions of the discriminator element can be varied, together with the release lever and with the mechanical striker elements.
