Definitions

  • the present invention relates to the field of the textile industry, in particular the treatment of the raw material after working and in particular sorting and elimination of pollutants in fibrous materials such as cotton or others, and relates to a device for detecting polluting materials.
  • drums or conveyor belts there are also mechanical transport devices of a sheet of material, in which the material is conveyed in sheet on mechanical means, such as drums or conveyor belts, and detection means are placed transversely to the material flow and issue an impurity removal command to means tires in the form of nozzles arranged under the carpet or in the drum.
  • the drum and the carpet are advantageously perforated and allow the passage of polluting material propulsion air to a corresponding receiving device.
  • the object of the present invention is to overcome these drawbacks by proposing a device for detecting pollutants in fibrous materials such as cotton or other, which allows to check simultaneously existence and elimination, in a flow of displaced matter pneumatically, mechanically or by gravity, of all products pollutants contained in said material.
  • the invention relates to a device characterized in what it basically consists of is the combination of means of optical detection and ultrasonic detection means arranged transversely to a flow of material transported from a machine of working, upstream of a means of extraction of pollutants, towards downstream processing machines.
  • the single figure in the accompanying drawing partially represents a sorting machine interposed between a processing machine and downstream processing, in which the material to be sorted is moved in front of a device 2 for detecting pollutants, which are ejected through an opening 3 of the machine.
  • the device 2 for detecting pollutants is essentially constituted by the combination of optical detection means 4 and ultrasonic detection means 5 arranged transversely to a flow of material transported from a working machine, upstream of a means 6 for extracting the materials polluting, to downstream processing machines.
  • the sorting machine is pneumatic and has a transport channel tire 1, in which the material to be sorted is propelled by through a pressurized air flow, forming an air mixture fibers or a sheet, and passes in front of the material detection device 2 pollutants, which are ejected through an opening 3 of said channel 1.
  • the invention is also applicable to machines sorting machines, not shown, in which the material is scrolled by using a mechanical transport device for a sheet of material, in which the material is conveyed in a web on a means mechanical, such as a spreader drum or conveyor belt, or still in which the air fibers mixture or the sheet is transported by gravity at the exit of a free accumulation means, such as a hopper or the like.
  • a mechanical transport device for a sheet of material in which the material is conveyed in a web on a means mechanical, such as a spreader drum or conveyor belt, or still in which the air fibers mixture or the sheet is transported by gravity at the exit of a free accumulation means, such as a hopper or the like.
  • the detection means constituted by the combination of means of optical detection and ultrasonic detection means, are placed transversely to the material flow, cooperate with the spreading drum or the conveyor belt, which are then preferably made in one ultrasound absorbing material, and issue an elimination command impurities in pneumatic means in the form of nozzles arranged under the carpet or in the drum, which are advantageously perforated and allow the passage of polluting material propulsion air to a corresponding reception device located opposite these nozzles.
  • a device involving a gravity transport of the air fibers mixture or of the sheet at the outlet of a fiber accumulation means, such as a hopper or the like said transport is carried out through a vertical transport channel, in which the material to be sorted falls under its own weight, forming an air mixture or a tablecloth, and passes in front of the device 2 for detecting materials pollutants, which are ejected through an opening 3 of said channel.
  • the optical detection means 4 are advantageously constituted by light bars emitting a light beam in direction of material flow through channel 1, or transported mechanically or transported by gravity in a vertical channel, and cooperating with receptor cells analyzing the contrasts appearing during the passage of light rays passing through matter transported or reflected by pollution. Any appearance of contrast important means the existence in the material flow of a product or a original material or constitution or different colors in front be eliminated by means of the extraction means 6 through the opening 3 of the channel 1.
  • the ultrasonic detection means 5 consist of at least a 5 'transmitter - 5 "absorber - 5"' receiver of ultrasound arranged on either side of the pneumatic conveying channel 1, of the vertical channel of gravity transport, or parallel to the mechanical transport device of the sheet of material, transversely to the flow of the latter and opposite of this transport device with respect to said material flow.
  • the 5 'transmitter continuously emits ultrasound in the direction of the absorber 5 "and the receiver 5" 'collects the ultrasound possibly reflected by pollutants passing through the beam emitted by the 5 'transmitter.
  • the 5 ′ transmitter emits waves of a length less than 1 cm and works at frequencies between 50 kHz and 200 kHz.
  • the transmitter 5 'of the means 5 ultrasonic detection is advantageously in the form of a elongated element of small thickness and the 5 "receiver is constituted by a large number of small individual cells and its width total substantially equivalent to that of the elongated element forming the transmitter 5 '.
  • the bandwidth of each individual cell forming the 5 "receiver is at least 4 kHz.
  • the transmitter 5 ′ advantageously has a width equivalent to that of the pneumatic transport channel 1, or of the mechanical transport device or to the depth of the vertical gravity transport channel. while the individual cells forming the 5 "receiver have a receiving surface of about 1 cm 2 at most and are arranged side by side without gap, also over the entire width of the transport channel pneumatic 1, of the vertical gravity transport channel or of the mechanical transport device.
  • the depth of the vertical gravity transport channel corresponds, in fact, to the dimension of the channel perpendicular to the direction of the material flow, therefore to the width of the pneumatic conveying channel 1.
  • the height of the pneumatic conveying channel 1 or of the mechanically transported ply or the width of the vertical gravity conveying channel can advantageously be 80 mm.
  • the receiver 5 "'is able to recognize a pollutant in about 0.5 ms.
  • Light bars illuminate the material passing through the flow of pneumatically propelled material or flowing by gravity, or passing on the spreading drum or the conveyor belt and simultaneously the ultrasonic transmitter emits waves towards said flow through the pneumatic transport channel 1 or the gravity transport channel, spreader drum or conveyor belt, so that all products pollutants passing through light and wave fields cause corresponding reflections towards the optical receivers and 5 "ultrasound and thus allow delivery by the control means computer extraction signals corresponding to means 6.
  • This extraction is controlled by means computer control not shown and not described in detail, which takes into account counts, on the one hand, the characteristics of the product to be treated, namely, by example, cotton and, on the other hand, the running speed of the air mixture free or of the product in the pneumatic conveying channel 1, or in the vertical gravity transport channel or on the mechanical transport of the sheet of material to trigger in good time means 6, that is to say at a time interval consecutive to the detection corresponding to the movement made by the pollutant detected so that it found in the area of action of the extraction means 6.
  • the extraction means 6 is in the form of a ramp of nozzles extending over the entire width of the pneumatic conveying channel 1, vertical gravity transport channel or transport device mechanical, opposite the pollutant elimination opening 3, these nozzles can be operated individually by the control means IT, according to the signals emitted by the optical detectors of the means 4 or by the individual cells of the 5 "ultrasonic receivers. as a result a transverse jet of compressed air can be delivered exactly to the location of the transported material flow, corresponding to the position of the pollutant previously detected by one of the aforementioned detectors.
  • the invention allows, on the one hand, to sort by taking into account existing contrasts, due to the very existence of different materials, both in colors and in their characteristics of own reflection and, on the other hand, to take into account transparent matters optical sorting, that is to say which cannot be detected by using optical means.
  • optical sorting that is to say which cannot be detected by using optical means.
  • the pollutants present in the flow of moving material for example cotton, could not date, be eliminated.
  • detection means implemented by the present invention makes it possible to discern, in a material flow, materials which were to date transparent to known detection means and which, therefore, could not be eliminated.
  • the invention makes it possible to obtain a material raw perfectly free of all pollutants. Because of the use of very small individual cells for the 5 "ultrasonic receiver. The invention makes it possible, in fact, to detect pollutions of very low importance and thus also eliminate these.
