Definitions

  • the present invention relates to a process and to a device for feeding pirns to the individual reeling points of a textile machine, e.g., an automatic coner machine, by using a tray conveyor means suitable for feeding a plurality of reeling points of various winding sectors prearranged to reel different threads; thus, the simultaneous processing of taking up of a plurality of thread batches along one single winding front becomes possible.
  • a textile machine e.g., an automatic coner machine
  • the pirn which is formed by a spinning frame, in particular a ring spinning frame, is subsequently unwound, and the thread is rewound on a rigid cone, to produce a cone 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 taking up 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 taking up unit 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 taking-up 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 taking-up units and the pirns to be fed to them.
  • specific threads have to be respectively fed to specific taking-up positions, without mixing the fed pirns.
  • the purpose of the present invention is to cause the production to be easily adjusted, according to the need for a plurality of different batches of thread being simultaneously taken up, in order to be flexible as a function of the various market areas, and to meet all of the users' needs.
  • coner machines are prepared, each taking up one or more thread types.
  • coner machines have been known in the art, which are equipped with a set of frontally predisposed storage units, a storage unit per each taking up 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 unwinding stations.
  • Conveyance arrangements are also known, wherein the pirns are received inside the trays fastened onto a conveyor belt which runs along a closed-loop path, along the whole working front.
  • 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 takes up 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 taken up after the end of the taking up 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 taking up front.
  • the present invention aimed at the purpose of providing a solution capable of overcoming such drawbacks.
  • a purpose of the present invention is to provide a device wherein an individual automatic coner machine can simultaneously take up a plurality of different thread types belonging to batches different in count, colour and composition. More particularly, the present invention consists in 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.
  • 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 use of 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, all the more that it is not an object of the present invention.
  • a valuable characteristic of the device of the present invention is its suitability for being applied both on the working fronts of the already existing machines, and on the working fronts of the machines under way of assemblage.
  • Another valuable characteristic of the present device is its operating way, which is prevailingly mechanical, in that, besides the drive unit driving the conveyor belt or chain, no electrical, electromechanical or electronic components enslaved to the device exist.
  • 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 spools will be equipped with advantageously prearranged 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 suitable for orienting and finding out the end of the thread of the pirns, and transferring them into the suitable conveyance trays 2.
  • 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 taking up sector 18A or 18B or 18C.
  • the station 8 when receives 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, A or B or C, which it is charging, predisposes the operative block of the dis­criminator lever 47 in the A or B or C position, 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 taking-up unit belonging to a winding sector is provided with a mechanical movable striker element 72 A or 72B or 72C, located in height (see Figure 2) in accordance with the type of pirn to be drawn 16A or 16B or 16C.
  • 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 72A or 72B or 72C come out, with a substantially horizontal shifting, to reach its position of mechanical interference with the corresponding release lever 52 in A or B or C position.
  • Said release lever 52 running together with the conveyance tray housing the pirn 16, yields by rotating during the interference step, around the central hinge of the discriminator lever 68, 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 taking up unit is made re-enter through a substantially horizontal shifting by using means known from the prior art, and the release lever 52 places itself, or remains placed, in a position of non-interference with possible subsequent striker elements 72A or 72B or 72C, placed in an interference position by the taking-up units which require a spinning pirn 16.
  • the conveyance tray returns empty back to the station 8 wherein the search for the pirn thread end is carried out.
  • 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 operative block of the discriminator lever 47 during the step of pirn charging to the tray by rotatably actuating the discriminator element 56 bearing, at its end, the contact roller 64, will cause the release lever 52 to assume an A or B or C position, corresponding to the type of pirn supplied to its own tray.
  • positions of the operative lever systems can be varied; a tray-holder conveyor belt can be envisaged, which is enabled in its running function at each drawing signal, and hence 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 element made integral, in a pre­arranged position, with the structure of the taking up unit.
