Definitions

  • the present invention relates to an improvement made to the devices making it possible to wind a fabric (fabric, knitting, etc.) on an appropriate support mandrel during the various stages of manufacturing said fabric (weaving, knitting, dyeing, finishing, etc.).
  • the knitted product is wound on a tubular support or mandrel which facilitates subsequent handling.
  • the first of these techniques consists in having an axial drive of the support mandrel, the drive speed of said mandrel being modified as the diameter of the winding increases so as to have a constant linear speed and a tension also constant.
  • the second consists in carrying out the drive by means of two carrying rollers on which the knitting winding rests (tangential carrying winding).
  • the system for communicating the pressure to the driving cylinders essentially consists of an articulated arm associated with a jack which, on the one hand, therefore necessarily limits the diameter of the winding capable of being formed and, on the other hand, significantly increases the floor area of the installation.
  • the device according to the invention overcomes the drawbacks of previous solutions and in particular, to produce a winding which is independent of the weight of the part, to considerably increase the diameter (therefore the weight) of the winding formed as well as to facilitate placing and removing the roll of formed material.
  • the device according to the invention makes it possible to avoid creating surface defects on the material and to carry out a winding without tension, in particular in the case of elastic knits, and this by having a correct unfolding of the selvedges.
  • the invention therefore relates to a device for winding a fabric (knitting in particular) during the various stages of its manufacture, device according to which the material is wound on a support mandrel, the drive being obtained by contact tangential with driving cylinders arranged above the winding, the device according to the invention being characterized in that the driving cylinders are at least two in number and are arranged symmetrically on either side of a plane vertical passing through the axis of said winding, these cylinders rotating at the same speed, exerting constant pressure on the winding and being mounted on a support capable of sliding along vertical uprights, arranged on each side of the machine, and this as the diameter increases.
  • the material is wound up on a mandrel supported by a carriage (or container) which can be used for transport and storage.
  • the reel according to the invention can be adapted either at the front or at the rear of the loom,
  • the driving of the driving cylinders can be carried out either by an independent motor or directly from the loom.
  • the speed can be adjusted using a potentiometer or a reduction gear and, in the second, by a gearbox.
  • the reel is disengageable compared to the trade.
  • the device according to the invention is associated with means making it possible to modify the pressure exerted by the driving cylinders on the winding.
  • the device according to the invention also comprises an element making it possible to ensure the unfolding of the selvedges, this element being, in one embodiment, constituted by an assembly comprising a rotary brush and a widening bar.
  • the structure and operation of the reel according to the invention is as follows, this reel being arranged either at the front or at the rear of a loom, knitting by example, profession not shown.
  • the knitted fabric (1) from the trade is wound on a cylindrical support (mandrel) (2) whose drive is obtained by tangential contact with motor cylinders (or rollers) (3,4) .
  • the engine cylinders (3,4) are at least two in number and are arranged above the winding (5) of material, symmetrically on either side of a vertical plane XX passing through the axis of rotation of the support mandrel (2).
  • the drive cylinders (3,4) are mounted on a chassis (6), by means of a roller holder consisting of two support plates (7) mounted to slide freely on guide posts (8), arranged in each side of the machine on the chassis (6).
  • the support plates (7) are guided on the uprights (8) by rollers (9).
  • the driving rollers (3,4) are mounted on bearings.
  • the drive of the rollers (3,4) is carried out in this embodiment, by means of a chain (10) driven by the loom, on a gear train (11) (or gear box) acting on a control axis (13) allowing a symmetrical drive on each side.
  • the transmission of the movement is obtained by means of a chain (14) which passes over sprockets (15, _ 16,17) and return elements.
  • the pinions (16,17) are mounted on the support plates (7) and therefore move with the latter.
  • the drive of the widening screw (21) and the border widening brush (22) is carried out, in this example, by means of a chain (31) controlled by an electric motor. (12) which passes over pinions (33) and return elements.
  • the pinions (32) and (33) are mounted on the support plates (7) and move with the latter.
  • a counterweight system is associated with the roller drive system so that the latter exert constant pressure on the winding.
  • This counterweight system is constituted, in the embodiment described, by an assembly (18) suspended in a casing (19) of the frame (6). It is connected, by means of belts or chains (29) to the support plates (7). It can extend over the entire width of the assembly or, as in the present example, simply on each side.
  • the two counterweights are connected by an axis (36) allowing a parallel rise and fall of the plates.
  • the winder is also associated with means making it possible to widen and unwind the edges of the knitted fabric.
  • These means are constituted by a conventional widening roller (21) comprising a surface with a helical profile, inverted on each side and by a rotary helical brush (22).
  • a widening system is shown in more detail in Figure 3 and allows, thanks to the particular structure of the drive system to act on the knitted fabric in close proximity to the driving roller.
  • the rotary drive of the spreader bar (21) and the helical brush (22) is obtained by the control chain (31) for the spreader bar and by means of the chain (20) for the helical brush.
  • the winding mandrel (2) is, for its part, supported in a container or trolley (25) capable of being moved, for example by means of a pallet truck.
  • the ends of the roller (2) are mounted in suitable bearings (39) provided on the sides of the carriage (25) under the bearing (30).
  • a second support winding (23) is also provided.
  • This bearing (23) allows exact parallelism between the rollers (3) and (4) and the mandrel (2) throughout the winding time.
  • the bearing (30) allows the unwinding of the finished part, for example in front of a train.
  • the bearing (23) is supported on an appropriate bearing (24) provided on the chassis (6), bearing adjustable in height as a function of the diameter of the parts (5) requested.
  • this winding system is as follows.
  • the container (25) equipped with the winding mandrel (2) is brought below the driving rollers (3,4).
  • the knitted fabric (1) leaving the loom is brought in the manner presented in FIG. 1 by passing around the enlarging system (21) and by wrapping one of the driving rollers, the roller (4) in the present case.
  • the counterweight system (18) has been previously adjusted according to the pressure which it is desired to ensure on the knitted fabric.
  • the winding (5) increases in diameter and, simultaneously, the rollers (3,4) on the plates (7) move vertically along the slide (8).
  • the piece (5) is released from the rollers (3) and (4) by the lifting crank (35) connected to the axis (361 of the counterweight chains (29).
  • the finished knitting piece remains in its container (25) (or on its trolley), is evacuated for example by means of a pallet truck and the container or the trolley are placed for the winding of the next part.
  • Such a winding system makes it possible to form coils of a very high weight, the diameter of the coil which can easily reach 1 m to 1.70 m, that is to say, to have a weight of material which can reach several hundred kilos.
  • Such a winding capacity is possible, in this case, by the fact that the pressure exerted by the driving rollers (3,4) remains constant and can be preset beforehand by means of the counterweights (18).
  • the winding speed can be very slow. It is therefore possible to obtain greater relaxation of the knitted fabric.
  • such a system can be easily fitted with widening means and brushes which act on the edge of the knitted fabric just before it passes over the drive roller (4).
  • Such a reel can have any width depending on the width of the knitted fabric.
  • the winding being independent of the weight of the part, the diameter of the wound fabric can, as said previously, be considerably increased.
  • the engine cylinders are only two in number, it could be envisaged, without departing from the scope of the invention, to provide additional engine cylinders (37) and (38) shown in dotted lines in Figure 1, which come to bear on the fabric winding formed only from a certain diameter of said winding.
  • the weight of these additional engine cylinders is of course also compensated for by the counterweight system.
