Definitions

  • the present invention relates to the field of the treatment of textile fibers, in particular by means of a card known as "for animal, vegetable and chemical fibers", in particular the loader intended to feed it with a sheet of textile fibers as regular as possible.
  • Known loaders of this kind generally receive their fiber reserve pneumatically, by manual loading or by loading well.
  • the reserve rests on a hood apron, is taken up by the spiked apron, is detached from the latter by the detacher and falls into the hopper with adjustable spacing and oscillating wall.
  • the delivery cylinders then place this reserve on the food apron supplying the card.
  • a photoelectric cell controls the level of fibers in the reserve and, as soon as a predetermined fiber height is reached, the cell is obscured, leading to a stop command of the fan bringing the bundles of fibers.
  • the level of fibers in the hood drops below the level of the cell, so that the latter is again released, the fan bringing the fibers is restarted.
  • the thickness of the fiber mat that the spiked apron takes to the hopper is controlled by another cell placed near said spiked apron.
  • the loading of the latter is carried out according to the same principle as that of the hood, that is to say that the thickness of the fiber mat is controlled by the cell which is obscured when said thickness is too large, which results in a loader stop command and, when the thickness of the mattress has returned to normal, the cell is released and commands a restart of the loader.
  • a third cell is placed at the entrance of the hopper and is intended to control the stop or the running of the loader, according to the same principle as that described above, depending on the height of the material in the hopper. .
  • the various control points of the loader control the latter in all or nothing, that is to say by stopping or starting it, which leads to various drawbacks for a card loader.
  • the routing of the material to the carding machine is necessarily discontinuous due to the discontinuous operation of the loader consisting of numerous stops and restarting of the latter, which entails the same drawbacks as described above, that is to say that is to say an outgoing product which is irregular and of poor quality and which generates significant variations in the specific weight of the mass of fibers.
  • the various constituent parts such as the hood apron, the spiked apron, the delivery cylinders and the regulating flywheel are controlled by a single speed motor, so that it lacks flexibility, which also contributes to the irregularity in card feeding.
  • the present invention aims to overcome these drawbacks.
  • a loader for feeding a card with a textile fiber as regular as possible which is essentially constituted by a hood supplied with fiber flakes by a fan, and provided with a fiber level control cell controlling the operation and stopping the fan, by a hood apron extending under the latter, by a spiked apron taking up the fibers brought by the hood apron, by a cell for controlling the thickness of the fiber mattress on the apron to spikes, by a hopper with adjustable spacing and oscillating wall loaded by the spiked apron and provided, at its lower part, with delivery cylinders cooperating with a food apron carrying out the feeding of the carding machine, characterized in that the hood apron is continuously driven at variable speed controlled by the cell for controlling the thickness of the fiber mat on the spiked apron, in that the hood is fitted, in addition re, at its exit, above the hood apron, a haspel for regulating the flow of
  • the figure of the appended drawing represents a loader for feeding a carder 14 with a sheet of textile fibers as regular as possible, which essentially consists of a hood 2 supplied with flakes 1 of fibers by a fan, not shown, and equipped with a fiber level control cell 3 controlling the start and stop of the fan.
  • a hood apron 5 is placed under the latter and brings the fibrous material 4 to a spiked apron 6.
  • the thickness of the fiber mat on the spiked apron 6 is controlled by a cell 7, then said mattress is brought to a hopper 11 with adjustable spacing and an oscillating wall loaded by the spiked apron 6 and provided, at its lower part , of delivery cylinders 12 cooperating with a food apron 13 carrying out the feeding of the card 14.
  • the loader is provided with a hood apron 5, which is driven continuously at variable speed controlled by the cell 7 for controlling the thickness of the fiber mat on the spiked apron 6.
  • the hood 2 is provided at its outlet, above the hood apron 5, with a haspel 8 for regulating the flow of fibers leaving said hood 2 and a regulating flywheel 9 at variable speed cooperates with the apron at tips 6 for regulating the fiber mat taken by the latter.
  • the fiber flakes 1 are brought into the hood 2 by the fan, not shown, and their level in said hood 2 is controlled by the cell 3 which, as long as it is cleared, maintains the operation of the fan and, as soon as it is obscured, commands the latter to stop.
  • the latter performs the control of the loader speed by allowing operation at normal speed when it is cleared and operation at predetermined minimum speed when it is obscured.
  • the position of the cell 7, relative to the spiked apron 6 and to the hood apron 5, is adjustable. So the thickness of the fiber mat on the ta blier with spikes 6 can be adjusted.
  • the fiber mat driven by the spiked apron 6 is further regulated by the haspel 8 and by the regulating flywheel 9.
  • the spiked apron 6 pours the bundles 10 of fibers into the hopper 11 to adjustable and oscillating wall spacing, by cooperation with the detaching cylinder 17, said hopper 11 supplying the card 14 via the delivery cylinders 12 cooperating with the food apron 13.
  • the hopper 11 is provided with two level control cells 15 and 16, arranged vertically apart, and controlling a device for regulating (not shown) the drive speed of the spiked apron 6 , delivery cylinders 12 and regulating flywheel 9, respectively at maximum speed when the fiber level in the hopper 11 is below the lower cell 15, at normal speed when the cell 15 is obscured and when the cell 16 is released and at minimum speed when the two cells are obscured.
  • a continuous level control in the hopper 11 and to maintain this level more or less constant by carrying out either a height adjustment of material, or a level maintenance, or a loss of height of material .
  • the loader according to the invention makes it possible to easily and easily adjust the thickness of the layer of fibers which it must deliver to the carding machine, so that the latter is fed in a regular manner and that the outgoing product is also regular and of good quality.
  • the routing of the fibers to the carding machine takes place continuously, owing to the fact that the loader rotates constantly, that is to say without stopping one of its constituent elements, which also contributes to the consistency and good quality of the outgoing product.
  • the movable members such as the hood apron 5, the spiked apron 6, the delivery cylinders 12 and the regulating flywheel 9 being controlled at variable speed, they have a certain flexibility of operation contributing to the regularity of supply of the card 14.
