Abstract

The invention relates to a bobbin supply system adapted to simplify the random replacing operation of completely exhausted bobbins to be replaced by completely full bobbins on a spinning frame. This supply system comprises at least a first path (1) coming from a bobbin frame and adapted to transfer a bobbin assembly or train arranged near a second path (1 min ) which extends on the perimeter of the parts constituting a spinning frame. The mentioned first path is provided with a conveyor belt driven with a substantially reciprocating motion, whereas the second path is provided with a conveyor belt having a substantially continuous motion, the system further comprising means for transferring individual bobbins (2) between the conveyor belts of the first and second paths (1, 1 min ).

Description

  • The invention relates to a bobbin supply system adapted to simplify the random replacing operation of completely exhausted bobbins to be replaced by completely full bobbins on a spinning frame.
  • This supply system comprises at least a first path (1) coming from a bobbin frame and adapted to transfer a bobbin assembly or train arranged near a second path (1') which extends on the perimeter of the parts constituting a spinning frame.
  • The mentioned first path is provided with a conveyor belt driven with a substantially intermittent motion, whereas the second path is provided with a conveyor belt having a substantially continuous motion, the system further comprising means for transferring individual bobbins (2) between the conveyor belts of the first and second paths (1, 1').
  • Such a system is conventionally called the set by set replacing system.
  • However, because of very different reasons, the bobbins of a given set do not exhaust at the same time or within a given short period of time.
  • Accordingly, this type of bobbin supplying system does not afford the possibility of exploiting in an optimal way the efficiency capabilities of the spinning frame, with a consequent increase of the operating cost.
  • Another system is to supply the bobbins to the spinning frame by sets or trains and, in this system, the bobbins are changed individually, that is upon sensing each single empty bobbin.
  • This second system, on the other hand, requires comparatively long operating times, which negatively affect the efficiency of the spinning frame.
  • The documents DE-A-3 601 832 and PATENT ABSTRACTS OF JAPAN Vol.11, No 262 (C-442) 2709 disclose a system for loading bobbins on and unloading bobbins from a spinning frame according to the pre-characterizing part of the main claim.
    • SUMMARY OF THE INVENTION
  • Accordingly, the task of the present invention is to overcome the above mentioned drawbacks by providing a spinning frame supplying system able of causing the spare full bobbins to be displaced in a continuous way along the front sections of the spinning frames.
  • Another object of the present invention is to provide a spinning frame supplying system which is adapted to greatly facilitate the replacing of empty bobbins by completely full bobbins.
  • Still another object of the present invention is to provide a bobbin supplying system which is very
    • reliable in operation.
  • According to one aspect of the present invention the above mentioned objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a system for supplying spinning frames with completely full bobbins, having the features of the characterizing part of the main claim.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • Further characteristics and advantages of the system for supplying spinning frames with full bobbins according to the present invention will become more apparent hereinafter from the following detailed description of a preferred embodiment of said system which is illustrated, by way of an indicative but not limitative example in the figures of the accompanying drawings,in which:
    • figure 1 is a schematic top view illustrating the supplying system according to the present invention; and
    • figure 2 is a cross-sectional view illustrating a spinning frame
    DESCRIPTION OF THE PREFERRED EMBODIMENT
  • With reference to the drawing figures,the improved system for supplying spinning frames with full bobbins according to the present invention preferably comprises two supplying circuits or paths, indicated generally at the reference numbers 1 and 1' including two conveyor belts and adapted to take up all of the bobbins 2 formed on corresponding roving frames 3.
  • More specifically,each said circuit or path comprises a first portion 4 associated with the corresponding roving frame and a second portion 5 adapted to transfer the full bobbin sets, sent from either roving frame,to a third common portion 6 so as to reach a switching device 7.
  • The mentioned third portion 6 adjoins a portion of a further circuit or path 8 which perimetrically extends with respect to the roving frames 9 and defines,through a switching device 10, two further portions 11 meeting,through corresponding switching devices 12, with the mentioned first portions 4.
  • At the adjoining portions of the first and second circuits or paths there are moreover provided an interexchanging apparatus 13 and a sensor 14 which will be discussed in a more detailed way hereinafter.
  • More specifically,the conveyor belt 15, defining the path 8 and carrying both full and empty bobbins is provided with a continuous motion and is stopped as the sensor 14 detects, near the apparatus 13, the presence of an empty bobbin,while a bobbin train coming from the path 1 or from the path 1' is arranged on a side of the mentioned apparatus 13.
  • The operation of replacing an empty bobbin by a full bobbin, in particular, is very easy.
  • In fact as an empty bobbin is sensed by the sensor 14, the operation of the path 8 will be interrupted (that is this path has an intermittent type of driving) so as to arrange an empty tube on a side of the apparatus 13, which will exchange this empty tube with a full bobbin, by supplying the bobbin to the path 8 and the empty tube to the path or circuit 1.
  • As the train arranged in a rest condition at a side of the mentioned apparatus 13 exclusively comprises empty tubes, the operation of said train will be started again so as to locate at said side another full bobbin train.
  • The empty tube train, in turn, will be sent, through the switching device 10, to the roving frame for forming new full bobbins.
  • In this connection it should be pointed out that the legs of the path 8 preferably laterally extend in an alternate way, one of this leg being sufficient to supply two adjoining roving frames.
  • From the above disclosure it should be apparent that the invention fully achieves the intended objects.
