Definitions

  • the object of present invention consists of a modular machine for spinning and doubling with individual transmission elements for spindles with continuous and individual conical or double conical folding system by means of conventional asynchronous alternative current motors controlled by frequency converters and programmed by a control or microprocessor unit.
  • the textile industry uses two types of the so called continuous spinning and doubling machines whic, among other elements, are provided basically with some elements, called spindles, in a number ranging from fiive units up to several hundreds in each machine. Said spindles are turning continuosly at the same speed, driven by only one electric motor by means of gear or pulleys assembly. Also, there is the possibility of having each spindle driven by an individual electric motor, with all motors controlled by a frequency variation unit so that all spindles turn at a same speed.
  • the modular machine for spinning and doubling with elements for spindles individual transmission with a continuous and individual conical or double conical folding system is made of a frame composed by two metal cabinets, one at the left and the other at the right hand side, with vertical cubic shape, made preferably in steel plate, each cabinet provided in its exterior side with a pivoting access door.
  • the central portion of said frame, connecting the two cabinets fastened by bolts, is provided with cross bars made preferably of welded steel tubes whic will act as a support for the different moving elements that will be described hereinafter.
  • the central portion of said frame contains within the space between both cabinets and held by the crossing tubes, from one to thirty spinning or folding spindles, each having its own driving means.
  • the spindles are turning vertical axis on which the different types of spinning or folding reels will be mounted.
  • Said spindles are held by a twin roller system of the ball type bearing.
  • the upper bearing unit is packed in connection with a synthetic rubber ring to absorb the radial vibrations and the lower bearing unit is mounted on a support of the swinging type which is allowed to be displaced radially.
  • the spindle bottom part has fastened a pulley arranged to receive a transmission flat belt, for connection to the output of an induction electrical motor mounted on a pair of crossing tubes placed in the back side of frame.
  • a ring rail having a vertical up and down displacement, on which a sliding piece rotates to create the twisting of the thread, is mounted coaxially on the spindle head.
  • a thread guide having a similar movement but with a different speed, said thread guide having the purpose of guiding the different threads towards the sliding piece coming from the hake box or feeding assembly.
  • the feeding assembly for each spindle comprises a pair of feeding rollers, an inlet thread roller and a pressure cylinder.
  • the feeding rollers made preferably of chromed carbon steel, are driven by means of two horizontal shafts, which are also driven, through a flat belt transmission system by an alternate current motor controlled by a conventional frequency variator controlled by a potentiometer, the whole assembly being located in the right hand side cabinet.
  • Said shafts are made of carbon steel and go through from one cabinet to the other supported by said cabinets, and a shaft is located vertically above the other, connected to each other by means of a chain that makes them turn in the same direction.
  • the pressure roller is located between the two feeding rollers and exerts a pressure on the thread in order to obtain a better draw, said pressure roller being held by means of ball bearings, the pressure arm is also fastened by means of bearings to another vertical shaft placed on top of those supported by the feeding rollers. Said pressure arm is allowed to move radially when actuated by a neumatic piston as to exert more or less pressure on threads moving through the pressure roller and feeding rollers.
  • the neumatic pistons acting on the pressure rollers of the feeding system in each spindle are driven by the pressured air flow coming from the air pressure piping system, with pressure regulated by a pressure control valve located in the left hand side cabinet.
  • spindles are the main elements that are in continuous movement, and are able to turn at different speeds;
  • the ring rail has a vertical up and down movement, with the sliding pieces and thread guides turning around and having, as in the case of the ring rail, a vertical up and down movement, the feeding rollers, the pressure rollers and the inlet thread rollers.
  • Each spindle turns around its own shaft driven by an alternate current induction motor by means of a belt preferably of the flat type with interior teeth.
  • Each motor is individually controlled by a frequency variator, preferably of the conventional, vectorial or other type, which is programmed independently for each spindle by means of a potentiometer located in each spindel control panel, so that each spindle can turn at a different speed and have a opposite turning direction.
  • the ring rail can move vertically along two vertical guides, one in each side cabinet.
  • Said guides are of cylindrical shape and are made of carbon steel and fastened in the bottom to each cabinet forming the machine frame.
  • Said ring rail moves vertically up and down with a stroke equivalent to the spindle reel height, being possible to regulate the length of said stroke.
  • the thread guides move above the ring rail, following a similar motion pattern, along said guides.
  • the ring rail as well as the thread guides are driven by an alternate current electric motor provided with a speed variator of the manual regulation disc type.
  • Said variator transmits the turning movement to a speed reduction unit by means of said flat teethed belt, the output of said reduction unit being an horizontal shaft driving two drums with a different diameter on which steel cables are wound which hold the thread guides and the ring rail.
  • the vertical up and down displacement is created as a consequence of the reverse in the motor turning direction by means of the control provided by limit switches mounted on said drums.
  • the thread guides and the ring rail are driven by same means and the same motor with reduction unit, so all have the same frequency of movement.
  • the feeding rollers are mounted on two horizontal cross shafts vertically one on top of the other and are driven through a flat belt transmission system by an alternate current motor controlled by a conventional frequency variator controlled by a potentiometer.
  • the turning movement is transmitted, between both of them, by means of a driving chain so that both shafts turn in the same direction.
  • the driving motor as well as the frequency variator and the control potentiometer are located in the right band side cabinet. Finally, the swing arm of each pressure roller is actuated by means of a neumatic cylinder.

  • the processed thread is inserted in the central body bottom part of said reel, driving the spinning and doubling machine so the reel turns driven by the spindle.
  • the process to obtain a bobbin is totally different from the conventional process.
  • the thread or welt is folded in accordance with a bobbin simple pattern with most of its lenght being of cylindrical shape and truncoconical upper portion
  • the folding pattern corresponds to a bobbin made up of multiple concentric cylinders and truncocones, forming assemblies called "subcycles", each of said subcycles comprising a smaller given number of thread or welt coats, with respect to the conventional system, and each subcycle having a height slightly lower than that of previous subcycle.
  • the assembly comprising a given number of subcycles is called "repeated great cycle".
  • the modular machine for spinning and doubling with individual transmission elements for spindles is provided with a control unit comprising a microprocessor which enables said machine to program, on a display, the length required to be stored in each reel, the reel length, the height (h) of the cone or truncocone, and by means of a display restricted to the user, the number of subcycles (m) and number of thread or welt coats in each subcycle (n) in accordance with the features of the processed products.
