Description

"Apparatus for spinning textile pieces and method used

work when using this

  The present invention relates to a device

  positive for the spinning of textile pieces assembled in a large band. In the dyeing industry, it has become customary, to subject them to the various operations necessary for their final preparation, to assemble by seams textile pieces whose average size is of the order of 50. meters; this operation carried out in a special workshop thus makes it possible to obtain textile strips whose length may be of the order of km 15. At the time of their introduction into the processing machine, such strips are closed again.

  on themselves by coarse seams and in relief. During treatment, especially

  re, these curls are made to rotate an endless movement, in machines such as for example de-

  Written in the unpublished document FR-A-91 00 857. On leaving these machines, the textile pieces contain a quantity of liquid of the

  from 2 to 3 times their dry weight It is therefore necessary to

  do a spinning operation of removing the treatment liquid from its support. In order to carry out this treatment, it has been thought to adapt to the textile industry spinning centrifuges comprising a perforated rotary basket controlled by

  high speed rotation; such wringers

  on the use of centrifugal force are in

  currently used successfully in many

  many branches of activity such as

  example, the agri-food industry or hematology-

  ogy. The adaptation of these spinning machines to the processing of textile belts whose size is of the order of one kilometer, however, posed numerous problems due to

  other than the pressure due to the

  addition to the weight of the processing liquid

  crushes the textile material and causes creases

  anarchic and often indelible breaks.

  In addition, twisting loading increased by that which may exist at unloading contributes to

  to hinder the good continuation of the works in continuous.

  Another disadvantage of the spinners that are currently on the market is linked to the extremely arduous nature of their load: the operator in charge of the maneuver must indeed lean mid-body in the basket of the wringer for

  distribute and balance the load; in addition, the

  immediately out of the dye release

  too much liquid falling on this worker.

  The aforementioned drawbacks make more than the kg / hour yield of these spinning operations

is extremely weak.

  The object of the present invention is to

  to overcome these disadvantages by proposing a

  for the spinning of textile pieces and more particularly

  of textile parts assembled in a large band likely to increase the yield

  and the quality of the spin, while at the same time improving

  ideally the convenience and comfort of the work of

  the user in charge of the maneuver.

  According to the invention, this device is

  it consists of a centrifugal centrifuge

  fuge classic type, that is to say provided with a perforated rotating basket rotated by a motor, a transport carriage for bringing the textile strip coming out of the machine and reopened close to the ci or away from it, as well as from organs

  transfer of the textile band from the trolley to the

  reuse or vice versa, these transfer members being mounted in height so as to raise the textile strip in the cart or wringer before

  introduce it into the wringer or cart and

  a set of at least two training rotors

is lying.

  The particularly advantageous nature of

  this device is mainly related to the configuration

  transfer bodies, and in particular

  their mounting above the trolley and the esso-

  at a height sufficient to allow

  the band, and thus avoid as much as possible all

  lage, entanglement or crushing of textile pieces

at this level.

  The training rotors can be

  conch without going beyond the scope of

  the invention; they are, however, advantageously

  staggered by a set of rotors formed of a central core provided, on its edge, blades whose adjacent portion of the outer edge is flexible; such bodies

  for example described in the document

FR-A-82 14 615.

  According to another characteristic of the invention

  the transfer members have two rings

  centering which co-operate with the training rotors.

  are respectively intended to receive the ex-

  tremity of the belt during loading or unloading

the wringer.

  Such rings, in which the end

  the tape is manually introduced by the opera-

  tor responsible for the maneuver, make it possible to exclude any defective positioning of the latter at the level of

transfer organs.

  Experience has shown that it is

  advantageously to be able to move the organs

  transfer between a loading position in the

  which drive rotors are located above the wringer and an unloading position in

  which they are located above the carriage.

  For this purpose, and according to a characteristic

  preferred embodiment of the invention, the transmission

  are constituted by a suspended pendulum

  hanging from a mast and likely to make a movement

  This pendulum assembly is preferably

  this set up in a protective case.

  A lid must of course close the door.

  soreuse after introduction of the textile band so

  to avoid any projection of liquid to the outside.

  According to another characteristic of the invention

  tion, the control motor of the rotation of the basket

  punched out of the wringer is a three-phase asynchronous motor

  phased to vary the speed and direction

of this rotation.

  The various organs mentioned above

  positive embodiment according to the invention can advantageously be controlled automatically from a unit

programming center.

  The invention also relates to the method

  implemented by the use of the above-mentioned

  tioned. This process is characterized by the following sequence of operations mentioned below: the transport carriage containing the conveyor belt is brought

  textile coming out of the processing machine near

of the centrifugal wringer.

  the end of the strip is grasped and introduced into the centering ring for loading the organs

  which have been previously placed in

loading.

  the activation of the training rotors is ordered

  is lying; the end of the band can then move

in the direction of the wringer.

  at the same time, low-speed rotation is

  the perforated basket of the wringer in a first

  meaning to ensure regular loading

of it.

  when the carriage is empty, the transfer members are moved to the unloading position for the purpose

  to be able to close the lid of the wringer.

  we then gradually increase the speed of rotation

  perforation of the perforated basket of the wringer; the character

  of this operation makes it possible to

  a large amount of treatment fluid

  before reaching the maximum speed.

  experience has shown that it is particularly

  to provide a maximum speed of around 3

  000 rpm and access it in about 3 minutes.

  after a predetermined step adjustable to this speed

  maximum, gradually decreases the speed of rotation of the perforated basket of the wringer

until complete stop.

  then open the lid and then seize the end

  mity of the textile band before introducing it into

  the unloading centering ring.

  at the same time, we order the start of

  twisting drive as well as low rotation

  speed of the perforated basket of the wringer in a se-

  cond meaning opposite to the first so as to exclude everything

  twisting and to facilitate the traction of the textile band

  tile. when the wringer is empty, all that remains is to move the transfer members to the loading position: the device is ready to perform

  the spinning of a new textile band.

  According to another characteristic of the invention

  automatically control the movement of the

  cover and transfer organs and the rock

  the perforated basket of the wringer and rotors

  from the central processing unit

  grammage which is constituted by a classical unit of this type which, for this reason, will not be described

  in more detail later in this talk.

  It has been verified that the use of the

  The aforesaid system is particularly advantageous, especially fast and convenient for the operator in charge of the maneuver; in particular, for a band of one

  length of about 1100 meters, the manual loading

  time of about 20 minutes; the use of

  transfer ganes according to the invention makes it possible to

  reduce this time to about 5 minutes.

  The features of the device as well as

  of the process which are the subject of the invention will be de-

  in more detail with reference to the

  in which: Figure 1 is a diagram showing the

loading the wringer.

  Figure 2 is an identical diagram but

  representing the unloading operation.

  According to FIGS. 1 and 2, the dewatering device is schematically composed of a centrifugal wringer 1, a transport trolley 2 and organs

transfer 3.

  The centrifugal centrifuge 1 which is of the conventional type is closed by a lid 4 and comprises in

  its internal part a perforated basket 5 driven in rotation

  according to arrows I and II by an asynchronous motor

  chrone three phase 6 The direction and speed of rotation

  of basket 5 can be reversed.

  A discharge orifice 7 makes it possible to evacuate

  outward water taken from the wringer.

  The carriage 2 is intended to receive a ban

  of textile 8 from a not shown processing machine and to bring it near the wringer 1

  in the position shown in Figures 1 and 2.

  According to the figures, the transfer members 3 consist of a pendular assembly suspended from a mast 9 at a point 10 situated at a certain height.

  above Wringer 1 and Trolley 2 This assembly

  ble can move, by a swinging motion

  schematized in the figures by the arc AB between a po-

  the loading unit shown in FIG. 1 and an unloading position shown in FIG.

  Transfer devices 3 are mainly

  constituted by a protective casing 11 made

  closing in its internal part a set of two

  12, 12 'in a manner known in the art.

  even, these rotors are each formed of a central core 13 provided on its blade edge 14 whose part 15 of the outer edge is flexible These rotors correspond in fact to those described in document FR-A-82 14 615 and will not for this reason not described here in more detail.

  The rotors 12, 12 'cooperate with two years

  centering rings 16, 16 'respectively intended to receive the end of the strip 8 during loading

  or unloading the wringer 1.

  The operation of this device is as follows: During a preliminary operation, the transport carriage 2 containing the textile strip 8 is brought near the centrifugal wringer in the position

  shown in Figures 1 and 2.

  The transfer members 3 are then

  in the transfer position shown in FIG.

  re 1 in which the rotors 12 and 12 'are

above the wringer 1.

  When the carriage 2 is in this position

  the operator in charge of the maneuver seizes

  the unillustrated end of the strip 8 and introduces it into the loading centering ring 16 The start of the drive rotors 12 and 12 'is then controlled and the whole of the strip 8 can be transferred according to the arrows III of the cart

  the low-speed basket of the perforated basket 5

  reuse 1 in a first sense, schematized by the arrow

  I in order to guarantee a regular loading of

  the latter. When the entire band has been transferred to the wringer 1, the transfer members 3 are moved into the unloading position shown in FIG.

  The rotational speed in the direction I of the perforated basket 5 is then progressively increased up to an adjustable predetermined value in which it is held for a time also determined so as to obtain a satisfactory spin. When this time has elapsed , the speed of rotation of the basket 5

  decreased again until complete stoppage.

  the circle is then automatically raised and the operator

  re-enter the unrepresented end manually

  felt from the band 8 to introduce it into the ring

  12, 12 'are then also started and the band 8 freed of its treatment water is in its entirety transferred according to the arrows IV in the

  carriage 2 to be taken to another

  A guiding cylinder 17 can, if necessary, facilitate this transfer. During this, the perforated basket 5 of the wringer 1 is rotated in rotation.

  low speed in a second direction II opposite to the first

  to exclude twisting and to facilitate

the traction of the textile band.

  When this operation is completed, it remains only to move the transfer members 3 again in the loading position shown.

  in FIG. 1 so as to make it possible to wring out another

to be textile band.

  The above operations are preferably

  automatically ordered in their entirety at
