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.
  • Figure 1 is a perspective view schematically showing the configuration of an automatic coner machine equipped with a device of the present invention
  • Figure 2 is an elevation sectional view of a device according to the present invention taken across the tray conveyor
  • Figure 3 is a top plan view of the device of Figure 2
  • Figure 4 is a sectional view similar to that of Figure 2, but showing the relationship between the pirn housing tray, in its open configuration, and a chute by means of which said pirn is fed to a receiver pin integral with a pirn carrier plate at a winding station.
  • 1 is an automatic coner machine producing cross-wound pirns
  • 2 is a conveyance tray housing an individual pirn
  • 4A is an automatic charging device suitable for drawing the A type of pirns, stored in bulk, prearranging them, in lined-up and parallel positions, on a conveyor belt, to convey them to operating means, such as pirn-orienting means, and means suitable for finding out the end of the thread on the same pirns
  • 4B is an automatic charging device suitable for drawing the B type of pirns, stored in bulk, prearranging them, in lined-up and parallel positions, on a conveyor belt, to convey them to operating means, such as pirn-orienting means, and means suitable for finding out the end of the thread on the same pirns
  • 4C is an automatic charging device suitable for drawing the C type of pirns, stored in bulk, prearranging them, in lined-up and parallel positions, on a conveyor belt, to convey them to operating means, such as pirn-orienting means, and means suitable for finding out
  • the operation of the device of the present invention is as follows.
  • the individually conveyed pirns are collected by the belt conveyor 10 which transfers said pirns to the station 8, suitable for orienting the pirn and finding out the end of the thread.
  • the automatic charging device for the C type of pirns is equipped with conveyor belts, to convey said pirns to the station 8.
  • the automatic charging devices 4A or 4B or 4C feed, with the respective pirns 16A or 16B or 16C, the station 8
  • the charging on the station 8 of a spinning pirn of A type, or of B type, or of C type takes place following a request signal coming from a winding sector 18A or 18B or 18C.
  • the station 8, upon receiving the spinning pirn 16, memorizes the type of pirn, and the position wherein said pirn is charged, such that, moment by moment, the operation of the same station, which is also a transfer device, is determined in its progressing by the knowledge of the location of the various pirn types it conveys.
  • the station 8 predisposes it and charges it, by a technique known in the prior art, into the proper 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 the discriminator element 47 in the A or B or C position namely with the end of the arm 56 in position 64A or 64B or 64C and the end of the arm 52 in position 52A or 52B or 52C, which witnesses the type of thread wound on the conveyed pirn.
  • the tray-holder conveyor belt 26 continuously transfers the spinning pirns 16 along the winding front of the automatic coner machine.
  • the automatic coner machine is subdivided into winding sectors 18A or 18B or 18C, wherein each winding station belonging to a winding sector is provided with a mechanical movable striker element 72 in position 72 A or 72B or 72C, located in height (see Figure 2) in accordance with the type of pirn 16A or 16B or 16C to be drawn.
  • the mechanical striker element 72 is in its rearwards-moved position.
  • the pirn-holder plate 28 revolves through one step, putting under unwinding the pirn previously charged in reserve position on a receiver pin 30, and makes the mechanical striker element 72 come out, with a substantially horizontal shifting, to reach its position of mechanical interference with the corresponding release arm 52 in position 52A or 52B or 52C.
  • Said release arm 52 running together with the conveyance tray 2 housing the pirn 16, yields by rotating during the interference step, around the vertical hinge 68 of the discriminator element 47, simultaneously causing the shifting, from its locking position, of the wing 50 which in its turn releases the movable bottom plate 36 of the conveyance tray 2.
  • the mechanical striker element 72 of the associated winding station is made re-enter through a substantially horizontal shifting by using means per se known, and the release arm 52 places itself, or remains placed, in a position of non-interference with possible subsequent striker elements positioned in position 72A or 72B or 72C at other winding stations which require a spinning pirn 16.
  • the conveyance tray returns empty back to the station 8.
  • the movable 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.
  • the discriminator element 47 during the step of pirn charging to the tray, by pivotably actuating the discriminator arm 56 causes the release arm 52 to assume position 52A or 52B or 52C, corresponding to the type of pirn supplied to its own tray.
  • the pivotal movement of the discriminator element 47 about the hinge 66 positions the ball 58 inside one of the hollows 62, with a stable and safe position of the discriminator element 47 and of the release arm 52 during their movement being obtained thanks to the urging by the spring 60.
  • Said spinning pirn delivered to, and housed inside, the conveyance tray 2, runs along the winding front, ready to be conveyed on a receiver pin 30, to feed a pirn-holder plate 28 of a whatever winding unit belonging to a winding sector 18A or 18B or 18C into which the automatic coner machine 1 is subdivided.
  • 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.
