Definitions

  • This invention relates to an apparatus and a method for conveying both winding tubes empty of wound yarn and winding tubes filled with wound yarn on holding pegs rigidly fixed to the upper part of a plurality of flat elements and for aligning the tubes in correspondence with the spinning spindles of a ring spinning machine, said apparatus being arranged to serve and to cooperate with an automatic doffing device in the ring spinning machine.
  • This apparatus for conveying and positioning winding tubes and the pegs holding said winding tubes, is used in operational correlation with an automatic doffing device which automatically removes the winding tubes filled with wound yarn from the spindles and replaces them with a like number of tubes empty of wound yarn to allow further yarn collection.
  • Said spindles are normally the spinning machine of a ring spinning machine.
  • the tubes when filled with yarn are the so-called yard packages, which accumulate the yarn spun by the individual spindles.
  • Ring spinning machines are already known which incorporate automatic doffing devices.
  • the preference is for a device with gripper elements projecting from a longitudinal bar which is driven with the necessary movement for simultaneously withdrawing all the tubes filled with wound yarn from the spindles and simultaneously positioning tubes empty of wound yarn on all said spinning spindles in suitable sequence. After each gripper element has handled one tube filled with wound yarn, it is made to grip a tube empty of wound yarn and mount it on the spindle.
  • the gripper elements the levers or the other means of the automatic doffing device do not form part of the present invention and can therefore be of any constructional type suitable for this purpose. They will therefore be neither represented on the accompanying drawings nor described in the description.
  • the automatic doffing device in ring spinning machines is known to function in operational correlation with conveyors in the form of two endless flexible steel belts, one for each spinning face, which are driven by drive rollers along suitable guides carried by a fixed structure which extends longitudinally along the entire spindle line.
  • Said flexible belt conveyors comprise a plurality of pegs fixed to them at regular intervals for holding and supporting both the tubes filled with wound yarn which the gripper elements of the automatic doffing device have removed from the relative spindles, and for receiving and holding the tubes empty of wound yarn which are to replace the yarn packages extracted from the spindles.
  • the flexible belt conveyors which extend along the entire length of the machine between the respective ends, can move horizontally and parallel to the machine length to bring the pegs coaxial with the axes of the various spindles.
  • the flexible belts are made to resume their intermittent or continuous movement along the front sides of the spinning machine, and as this latter again starts to newly accumulate wound yarn the tubes filled with wound yarn are unloaded from the respective support pegs by known means and also, by known means, new tubes empty of wound yarn are loaded onto the pegs.
  • a conveyor apparatus of this type with flexible belts for moving the winding tubes is presented and described for example in US-A-3 382 659.
  • current ring spinning machines can comprise many hundreds of spindles along a single working face. When the tubes are full of wound yarn they are withdrawn from the relative spindles and deposited in ordered arrangement on a belt or conveyor element.
  • the conveyor system or device of the aforesaid U.S. patent and others of the known art operate on the friction drive principle. Devices of this construction are subject to more or less extensive slippage if the conveying length is long. To limit this slippage to acceptable values a considerable increase in the installed tension of the flexible conveyor belt is required in order to increase the contact pressure on the drive roller and so increase the friction force along the contact arc between said drive roller and the inner surface of the flexible belt which wraps it.
  • This belt is susceptible to longitudinal elastic deformation, which increases as the installed tension is increased and therefore gives rise to a increasing linear non-uniformity in the distance between the peg which hold the winding tubes. This compromises the operation of the entire conveying system during the action of the aforesaid automatic doffing device in the ring spinning machine.
  • said lateral guides have to act with force-against the longitudinal edges of the flexible belt to retain it within the guide, and this results in rubbing friction which because of its abrasive effect is damaging for the entire flexible belt and increases the power required to drive said belt.
  • the object of the present invention is to obviate the aforesaid drawbacks by providing an apparatus and a method for conveying winding tubes filled with wound yarn or empty of wound yarn and for aligning them in correspondance with the spinning spindles along the faces of a ring spinning machine, which have the following advantages:
  • 1 is a flat element comprising on its upper part holding pegs, of which in the proposed preferred application one peg holds and supports the winding tube empty of wound yarn and the other peg holds and supports the winding tube filled with wound yarn.
  • Said flat element 1 rests by gravity on the upper surface of an underlying mobile drive belt.
  • 2 is the tube empty of wound yarn mounted on one of the two pegs which are rigidly fixed to the flat element 1.
  • 3 is the machinery housing of the ring spinning machine having two opposing spinning faces formed from some hundreds of adjacent spindles one adjacent the other.
  • 4 is the last element of the articulated chain ready to engage with the lever mechanism of the tensioning brake.
  • 5 and 6 are the mobile flat belts arranged along the respective spinning faces to support and drive the articulated chain of mutually connected flat elements 1. Said endless mobile belts can be advantageously driven with continuous motion and thus free of electrical or electronic locks linked to the operating cycle sequences relative to the withdrawal, insertion and positioning devices for the winding tubes.
  • 7 are the end structures, one opposite the other, of the ring spinning machine.
  • 8 and 10 are arrows indicating the respective directions of motion of the upper branches of the two endless mobile belts 6 and 5.
  • 9 and 11 are the respective idle return rollers for the two endless mobile belts 6 and 5.
  • 12 and 14 are the respective drive rollers for driving the endless mobile belts.
  • 15 is the block for transmitting motion to the drive rollers 12 and 14.
  • 16 are the pegs for holding and supporting the winding tubes 2. Said pegs 16 are fixed rigidly to the flat elements 1 by a lower shank pin 17 about which a connecting rod 25 is pivotally engaged to form the swivel joint for two consecutive flat elements 1.
  • 18 is a threaded element rigid with a respective flat element 1 and screwed into the respective connecting rod 25 to allow the precise and adjustable axial positioning of two consecutive flat elements 1.
  • 19 is a position transducer which cooperates with identifiable means 21 applied to the lateral surfaces of the flat elements 1.
  • 20 is the drive source for operating the drive rollers 12 and 14.
  • 22 is the support slide for the lever mechanism of the tensioning brake. Said slide 22 is normally stationary in position 22 and moves into position 22a when it is required to move the lever mechanism of the tensioning brake together with the articulated chain through a distance equal to the distance between the axes of the two pegs 16 fixed on a single flat element 1, ie the pitch of said consecutive pegs 16.
  • 24 are blocking levers operated by known means for engaging between the flat elements 1 and causing them to advance intermittently.
  • 25 is the connecting rod which connects two consecutive flat elements and which at one end is connected to the pin shank 17 to form the swivel joint and at the other end 13 connected to the threaded element 13 to allow adjustable axial positioning.
  • 26 is the articulated chain formed from the plurality of flat elements 1 which surround the ring spinning machine.
  • 27 (Fig.1) is the device which contains both the accumulation of tubes 2 empty of wound yarn and the known means for mounting said tubes 2 in the direction of the arrow 46 onto the pegs 16 of the flat elements 1.
  • 28 is the container bin for the tubes 50 filled with wound yarn which are conveyed into it by the chute 29 after being seized and withdrawn from the pegs 16 by any known withdrawal device 52, the linkages or operating means of which are located in the block 30.
  • 32 (Fig.3-5) is the actuator which moves the support slide 22 for the tensioning brake.
  • a tube filled with wound yarn which is withdrawn from a spindle by the gripper element of the automatic doffing device and held on a peg 16 to be then moved by the articulated chain 26 to its position for withdrawal and conveying in the direction of the arrows 48 to place it in the bin 28.
  • 33 is a section bar or structure of suitable shape which acts as a lateral guide track, and along the portions free of the mobile belt acts as the track for supporting the flat elements 1 of the articulated chain 26.
  • Said guide and support section bar 33 passes around the end structures 7 of the spinning machine and about the whole spinning machine forming an endless slide track.
  • 34 is the rod of the actuator 32.
  • 35 and 36 are the levers of the tensioning brake lever mechanism which engage with the frusto-conical sides of the last flat element 4. Said engagement is implemented by the action of the actuator 44, which by pressing the levers 41 and 42 pivoted on the pivots 39 and 40 causes the levers 35 and 36 to gradually approach the frusto-conical sides of the flat element 4 with the aid of the elastic elements 43.
  • 37 and 38 are two mechanical positioning elements in the form of brackets fixed rigidly to the levers 41 and 42, against said brackets there being positioned the two levers 35 and 36 at the end of their engagement with the flat element 4.
  • 6a, 6b and 6c (Fig.8) are endless mobile flat belts which can replace the belt 6 and which together cover one whole spinning face, their motion being perfectly identical.
  • 5a, 5b and 5c are endless mobile flat belts which can replace the belt 5 and which together cover the other spinning face, their motion being perfectly identical. Their upper branches are driven in the direction indicated by the arrow 10. 55 are optional mobile flat belts in a transverse position, they being driven substantially with the same motion as the longitudinal belts 5 and 6.
  • the winding tubes 2 empty of wound yarn are already, as shown in Figure 1, arranged in a position in front of the spinning spindles awaiting operational correlation with the automatic doffing device which when a winding is complete replaces the tubes filled with wound yarn and mounted on the relative spindles, with said tubes 2 empty of wound yarn and held stationary on the pegs of the articulated chain 26.
  • the winding tubes 2 are held in a line on alternate pegs at a distance apart equal to the spindle pitch, the spindle pitch being the distance between the axes of two adjacent spindles.
  • the gripper elements firstly remove all the tubes filled with wound yarn simultaneously from both spinning faces by withdrawing them from their spindles and immediately mounting them on the free pegs 16 which alternate with the tubes 2 empty of wound yarn.
  • Said free pegs 16 are stationary in positions perfectly coaxial with the axes of the various spindles, this correct precise location being determined by the clamping action of the levers 35 and 36 of the tensioning brake (see Figure 5), while the endless belts 5 and 6 exercise by their movement according to arrows 8 and 10 the tensioning and aligning action on the individual flat elements 1.
  • the gripper elements are released and rise from them, after placing them on the relative pegs 16, by the distance needed not to obstruct the subsequent movement of the articulated chain 26.
  • the same gripper elements are preferably made to grip tubes empty of wound yarn and mount them on the spindles.
  • the gripper elements can be of any construction suitable for the purpose. However it is preferable to use gripper elements of a type such as those described in EP-A-0 290 063.
  • the actuator 32 is then activated to move the slide 22 into the position 22a (see Figure 5, dashed-line position).
  • the entire lever mechanism of the tensioning brake which continues to clamp the flat element 4, moves rigidly with said slide 22 to produce the aforesaid movement of the articulated chain 26. This latter advances through one half the spindle pitch by the dragging action of the endless mobile belts 5 and 6.
  • the mobile belts 5 and 6 are preferably operated continuously at least during the entire doffing cycle so that by the friction dragging action which they exert on the flat elements 1 they produce a continuous positioning tension throughout the articulated chain 26.
  • Said positioning tension which arises by the simultaneous cooperation between the clamping action of the levers 35 and 36 of the tensioning brake and the dragging movement according to arrows 8 and 10 of the endless belts 5 and 6, is necessary to preserve the alignment of the flat elements 1 along the two horizontal longitudinal sections of the spinning faces of the spinning machine, and also to ensure operational coaxiality between the holding pegs 16 and the axes of the many hundreds of spindles.
  • the expulsion of the individual winding tubes 50 from the respective pegs 16 of the articulated chain 26 can be continuous or intermittent in known manner.
  • the insertion mechanism and pickup device can be of any known type suitable for the purpose.
  • Said endless mobile belts 5 and 6 are driven by the same drive source 20 (see Figures 1 and 6) which by way of a reduction gear and inverter block 15 causes the two drive pulleys 12 and 14 to rotate substantially synchronized but in reverse directions. These latter drive the two endless belts 5 and 6 at a substantially identical rate, their upper branches moving in opposite directions in accordance with the arrows 10 and 8.
  • the articulated chain 26 is adjusted in length by making micrometric adjustments on the screw connections between the elements 18 and the connecting rods 25 of consecutive flat elements 1, this precision then not changing with time because their movement within the apparatus of the present invention does not involve any forced dragging, the sliding of the chain also being smooth about curves because of the facility for considerable swivelling between said flat elements 1 (see Figure 7).
  • the belts 5 and 6 shown in Figures 1 and 6 for moving the articulated chain 26 are only one example of the many possible dragging means, such as moving by several short-length belts disposed along the individual spinning faces. They are driven in the same direction and in substantial synchronism along their individual spinning face.
  • Figure 8 shows one possible arrangement in which the belts 5a, 5b and 5c are driven in the direction indicated by the arrow 10 whereas the belts 6a,6b and 6c of the opposite spinning face are driven in the direction indicated by the arrow 8.
  • Figure 8 also shows the presence of transverse belts 55 which can be installed to improve the movement of the articulated chain 26.
  • the aforesaid embodiment involving two or more dragging belts enables two spindle faces, one opposite the other, to be served with a single articulated chain, and a construction of this type cooperating with an automatic doffing device acting simultaneously on both faces is therefore economically interesting.
  • an installation can be desirable consisting of a double apparatus of the type according to the invention, one for each spinning face, to cooperate with an automatic doffing device which operates on only one face of the spinning machine independently of the other face, to allow spinning of different batches of yarn.
  • Each apparatus in this case extends horizontally about the spindle line of one spinning face in an arrangement comprising a return track for the articulated chain entering and underlying the machinery housing 3 of the spinning machine. Both apparatuses then assume an arrangement symmetrical to each other about the longitudinal axis of the spinning machine.
  • the pegs 16 could be fixed one following the other on the flat elements 1 at a distance apart equal to the spindle pitch of the ring spinning machine.
  • the gripper elements of the automatic doffing device would firstly remove the tubes filled with wound yarn from the spindle and place them temporarily on stationary pegs fixed to a rod or similar element fixed rigidly to the spinning machine frame, to then grip the tubes empty of wound yarn and fix them onto the spindles, and then again grip the tubes filled with wound yarn and transfer them from the pegs on which they are held to the pegs 16 of the flat elements 1 of the apparatus according to the invention.
  • Such an automatic doffing cycle and device are known in the art and thus no further description is necessary. It is apparent that in this latter modification the slide 22 of the tensioning brake would no longer be moved through the aforesaid half spinning spindle pitch.
  • the apparatus must also be made compatible with the movement of other elements such as travelling cleaner devices, yarn rejoining trolleys etc.
  • the number of pegs 16 fixed on each flat element 1 can vary; the shapes and dimensions of said holding pegs 16 can vary; a single transfer belt could be provided extending along the entire spinning face opposite that spinning face comprising the tensioning brake; a plurality of transfer belts could be provided driven with identical or slightly different speeds; dragging elements other than belt elements could be provided; it would also be possible to provide a different lever mechanism for the tensioning brake; and drive sources could be added or removed to advantageously coordinate the movement of the dragging belts with all the various operating stages of the devices provided in the apparatus of the present invention.
