Definitions

  • This invention concerns a method and an apparatus suitable to feed cans to textile machines.
  • the invention provides for the automatic feed of cans full of textile sliver to, and the automatic removal of empty cans from, textile machines and, in particular, spinning machines of the open-end type.
  • the invention concerns in particular, but not only, cans of an elongate type, namely cans having one dimension of their horizontal section greater than the other, such as the rectangular cams to which we shall refer as an example in the description which follows.
  • These textile machines may all be those which process slivers held in cams, such as fly frames, spinning machines and, in particular, the open-end spinning machines to which we shall refer as an example in the following description.
  • the trolleys work at one machine side at a time along set paths and handle the normal round cans. Examples of these solutions are disclosed in WO-A-06358, FR-A-2.367,843, DE-A-3.440.598 and DE-A-3.505.494.
  • the present applicant has the purpose of providing a method and relative apparatus suitable to handle full cans and empty cans, preferably of an elongate type, by placing them directly to feed a spinning machine or other textile machine or by removing them from their feed positions.
  • the invention arranges that one or more movable trolleys, the number of which depends on the spinning machines of which the plant consists, cooperate directly with sliver production machines such as drawing frames, for instance.
  • Each drawing frame fills with sliver elongate cans which, when filled, are loaded automatically onto movable trolleys for delivery to the spinning zone.
  • the trolley After a full elongate can has been loaded, the trolley is sent on a path through the spinning machines.
  • the trolley can move automatically along pre-set paths and can be, for instance, of a type guided by a magnetic guide wire; it passes in one single direction between pairs of adjacent spinning machines. As it is equipped with means to communicate with spinning units requiring a change of feed, it turns the full can, in correspondence with those units, towards the side of the machine to which those units belong.
  • the trolley of the invention during its passage can feed equally well either of the the contiguous spinning machines and can turn the full can towards either of those spinning machines.
  • the can is unloaded from the trolley and positioned directly in correspondence with the spinning unit for which the can has been requested.
  • the trolley is also provided with suitable means to withdraw and to load on the trolley the empty can to be removed, and the empty can is unloaded automatically thereafter at the drawing frames or at any desired collection station.
  • the trolley can also be equipped advantageously with means to engage the pre-positioned end of the sliver on the full can.
  • the end of the sliver can be brought to cooperate directly with the spinning unit in the automatic restarting of the relative spinning process.
  • the invention provides a working method and apparatus which are well adapted to present spinning requirements, particularly as regards open-end spinning machines fed from rectangular cans or cans of any other elongate shape.
  • the invention can be applied also to other cases relating to various machines that process sliver, for instance in the handling of cans between the drawing frames and the fly frames, and intermediate stations may also be included for the storage of full and empty cans.
  • Fig.1 shows a possible lay-out of a spinning shop containing open-end spinning machines 10 and drawing frames 11.
  • Elongate cans 12 are filled with sliver in the drawing frames 11 and are removed therefrom on movable trolleys 13 which provide a secure connection between the open-end spinning machines 10 and drawing frames 11.
  • a full can, bearing the reference 112, is loaded on the trolley 13 in a neutral or waiting position, as will be described better hereinafter.
  • the trolley 13 follows a path 14 connecting the drawing frame 11 to a main path 15 according to the arrow 16 and runs along a part or the whole of the first side of the first open-end spinning machine 10.
  • the full can 112 is positioned on the trolley 13 on top of a rotary platform 17, which can be actuated to rotate by 90° clockwise or anticlockwise according to the arrows 18 (see Figs.2 and 3).
  • the position called "neutral" of the full can 112 on the platform 17 is such that the can 112 is located at a right angle to the analogous cans 12 taking part in the processing on the spinning machines 10 while the trolley 13 is moving on the main paths 15.
  • the full can 112 is therefore ready, whether it is travelling on the segment of path outside the first spinning machine 10 or on the segment of path between the spinning machines 10 (see Fig.2), to be rotated in one direction or the other (position shown with lines of dashes in Fig. 2) according to the arrows 18 so as to meet the requirements for feed of a full can 112.
  • the movable trolley 13 is equipped with at least one space to hold an empty can 212 taken from the spinning machines 10; this empty can 212 is advantageously positioned perpendicularly to the full can 112 when the latter is in its neutral position.
  • a trolley 13 is travelling towards the zone of the drawing frames 11 and is carrying the only empty can 212 to be removed.
  • the trolley 13 can run advantageously along direct return paths 19, which can be used equally well for its outward journey if it has to reach the farthest spinning machines 10 directly.
  • the trolley 13 is equipped preferably with means suitable to engage the end of the sliver 20 pre-positioned on the full can 112.
  • Such means may be a pair of rotary and possibly telescopic arms 21 which bear a terminal gripper assembly 22.
  • Each rotary arm 21 is located at a lateral position on the trolley 13 so that it can descend vertically according to the arrow 23 to grip the end 20 of the sliver whether the full can 112 has been rotated to the right or the left.
  • the arm 21 is rotated according to the arrows 24 and is possibly extended to take the end 20 of the sliver directly to a spinning unit which is to be restarted or to an automatic carriage which restarts the spinning and which is positioned, as is known, on the spinning machine 10.
  • Each arm 21 may bear, equally well, terminal assemblies 25 to discharge a full can 112 from the trolley 13. These discharge assemblies 25 descend vertically according to the arrow 23 to cooperate with the inner upper edge of the full can 112 and discharge the full can 112 thereafter from the trolley 13 by means of rotation of the arm 21 according to the arrows 24.
  • one rotary arm alone 21 is provided and is located in a central position, advantageously on the rotary platform 17, and carries out discharge of the full can 112 either to the right or the left of the trolley 13.
  • the trolley 13 is also equipped with an assembly 26 to engage and handle empty cans 212; this assembly 26 may be able to slide and extend and may be equipped advantageously with magnetic means capable of being coupled to analogous magnetic means 27 included on the cans 12.
  • Fig.3 shows an assembly 28 which actuates and controls the functions cited above of the trolley 13.
  • Figs.4a and 4b respectively show as an example a lengthwise section and a plan view of a known type of elongate can 12 which can be used with this invention.
  • the can 12 has a rectangular section and a movable bottom 29, which cooperates with springs 30 and with a pantograph-type balancing system 31.
