Description

i 2530683 The invention relates to an installation for drying coils

  wet-processed yarn, including a centrifuge

  for pre-dehydration and a high frequency dryer

sant following this.

  In known installations of this kind, the spools of wire having been treated wet in a column arrangement on perforated tubes are first removed from the tubes, then inserted one by one into a centrifuge where they are pre-dehydrated. case, we slide the coils one by one on a mandrel arranged coaxially in the center of a centrifuge drum which corresponds to the volume of a coil

  of wire and they are rotated around their axis, or else they are

  pose by group in a circle around the center of a drum of dimensions

  sufficiently large and they are rotated, these coils being protected

  by means of retaining devices provided on the inside of the wall

  side of the drum, against excessive deformation due to central forces

trifuges which come into action.

  These two centrifugal executions require a relatively long time for the feeding and removal processes and,

  given the small capacity, the acceleration and deceleration times

  furthermore have particularly negative effects on

  the coil rate that can be obtained per unit of time with these cen-

  trifugeuses. Transferring the different coils from the centrifuge to a subsequent high-frequency dryer requires

  corresponding time, so that the drying of a determined number of bo-

  bines takes a relatively long time and, in addition, the multiple manipu-

  the different coils require too much labor

  aunt. The object of the invention is to provide an installation for drying coils of wire treated by the wet process, by means of which it is possible to obtain a significantly higher rate of coils per unit of

  time than in known installations and which makes it possible to avoid

  repeated injections of the different coils.

  Starting from the installation defined above, to re-

  to solve the problem posed, it is proposed that to the centrifuge be added a receiving plate which can rotate around a vertical axis, on which can be placed a support carrying columns of spools of treated wire

  wet, and that above this receiving plateau and the centri-

  runaway is located, in a linear fashion, a conveyor comprising a lifting device and leading to the high-frequency drying apparatus, at

2 2530683

  by means of which columns of coils can be individually bound

  centrifuged, withdrawn therefrom and brought to the

high frequency drying.

  The receiving plate according to the invention allows, in a single E dporation, I simultaneously receive a load of columns of coils 8 ^ wire treated by wet process in the form of a ring of coils Using the transporter and its machine lifting, coil columns

  can be removed individually or together from the holder and inserted

  in the centrifuge After pre-dehydration, you can introduce

  these columns of coils in the high frequency drying apparatus Con-

  In contrast to known installations, it is possible to pass the coils through the drying process, not one by one, but grouped in columns.

  According to one embodiment of the invention, between the center

  the centrifuge and the high-frequency drying apparatus, there is a receiving frame in which the columns can be placed using the

lifting gear carrier.

  The receiver frame according to the invention, in which, according to its design, the columns of coils can be arranged in a circle as on

  the receiving tray and in the centrifuge, or again, in one or more

  rows, constitutes a buffer zone, so that despite the feeding-

  discontinuous operation of the receiving plate, the power to the

  High frequency chage can be done continuously.

  According to another embodiment of the invention, the center

  trifugeuse comprises a drum provided with shells, arranged in a crown

  has its inner circumference, vertically aligned, open in direction

  tion of the axis of the centrifuge and whose diameter is adapted to that

coil columns.

  -The Shells according to the invention provide support for the co-

  "O lons of spools of thread over their entire height, so that the forces

  which act on them cannot deform in particular

  neither the coils taken individually, nor the columns of bobi-

  nes. According to another embodiment of the invention, the frame

  receiver can also consist of a base plate that can turn

  ner around a vertical axis and on which are fixed, in the form of a cou-

  ronne, frame shells practically vertically aligned, open

  towards the edge of the plate and whose diameter is adapted to that of the co-

lons of coils.

  Thanks to this design of the invention, the receiver frame can be supplied with a complete ring of coil columns as simply as with individual columns and the frame shells, open towards the edge of the plate, facilitate the removal of the columns,

  one by one, for powering the high frequency dryer.

  In addition, according to one embodiment of the invention, the

  high frequency dryer is equipped with a conveyor in con-

  continuous, following the lifting gear carrier and / or arriving at-

  above the receiving frame and which is provided with load-bearing elements, intended for

  spool columns and arranged one behind the other, with a circle

  tain spacing from one to the other.

  Thanks to this design according to the invention, it is possible,

  simple lesson, suspend the different columns of coils from the successive load-bearing elements of the continuous conveyor and transport them in

  this position through the high frequency dryer.

  Finally, according to another embodiment of the invention, the load-bearing elements, intended for transporting the columns of coils through the high-frequency drying apparatus, each consist of a hook member to which can be hung at least a column of coils. According to the drying capacity of the high-frequency drying apparatus, the conveyor can be equipped with carrying elements which follow one another suitably close together.

  load-bearing elements can also have a structure allowing

  have several columns of coils per carrier element.

  An embodiment of the installation, in accordance with the

  vention and given by way of nonlimiting example, is shown diagrammatically

  Only in the accompanying drawings in which Figure 1 is a side elevational view and 1 _t 5 f = Xrei? -st nn vi I Pn plani-e 1 installatinn, which produces the longitudinal treatment remain in the

  lower ends of these tubes 8.

  These tubes 8 can be removed from the support 7 with their flanges 11, so that the columns of coils 6 can be removed one after the other from the support 7, using a conveyor with lifting device (not shown), and introduced into a drum 12 of the centrifuge 2 For the radial support of the coil columns 6 are provided,

  at the inner circumference of the side wall of the drum 12, co-

  pins 13 open towards the axis of the centrifuge which, on the one hand, are of sufficiently stable execution to maintain the shape of the columns 6 comprising the coils 9 and which, on the other hand, are provided permeable so that the liquid expelled from the coils 9, during centrifugation,

can flow without obstacle.

  By means of the lifting gear conveyor which passes linearly over the receiving plate 1 and the centrifuge 2, the columns of coils 6 are removed one by one from the centrifuge 2.

  after the end of the pre-dehydration and they are placed in the receiving frame

  tor 3 For this purpose, this receiver frame 3 is equipped, on a plate of

  base 15 can also rotate around a vertical axis 14, of shell-

  the frame 16, which are arranged in a crown and open towards the

edge 17 of the plate.

  Coming from the shells 16 of the receiving frame 3 supplied discontinuously with columns of coils 6, the columns 6 are suspended continuously from hook members 18 of carrying elements 19 of a

  transporter that runs through the high frequency dryer 4.

  It is only when the coil columns 6 have dried

  day in the high frequency dryer 4 and that the coils 9

  are completely dried as columns 6 are broken down into separate coils

ready 9.
