Definitions

  • This invention refers to a mobile anti-noise, anti-pollution and anti-accident comprehensive protection device for textile machines.
  • textile machines are usually pieces of equipment of large dimensions constituted by numerous mechanical parts in continuous alternating and rotational movement. Owing to this fact, textile machines have a high noise level which often exceeds the tolerance threshold of the human ear, thus making the working environment particularly uncomfortable for the workers.
  • the yarns which are treated by the textile machines move at a very high speed, for example the rotating spindles turn at a speed of between 6,000 and 25,000 rpm (revolutions per minute).
  • the high speed of rotations imparts a strong centrifugal force on the yarn which causes the detachment of particles from the yarn.
  • Another problem is due to the fact that the environment in which the textile machines are found is maintained at a considerable level of humidity to assist the textile handling of the yarns. These humidity levels which can arrive as high as 80% contribute to making the work environment even more uncomfortable.
  • the object of this invention is to provide a device which is able to reduce considerably the noise generated by these machines, eliminate the dust which pollutes the air, eliminate the high level of humidity in the working environment and eliminate the danger of accidents.
  • a mobile anti-noise, anti-pollution and anti-accident comprehensive protection device for textile machines characterized in that it is constituted by a case made of sound-absorbent material open at its lower base and shaped in order to completely isolate a textile machine from the external environment.
  • number 1 indicates the device which is the object of this invention, and it is constituted substantially by a case 2 made of sound-absorbent material.
  • Case 2 is open at its lower base so that by making it descend from above, as described hereinafter, it can completely cover a textile machine 4.
  • the case has the form of a parallelepiped, but it is evident that it may be realised in any other form in order to be better suited to the textile machine which must be isolated from the external environment.
  • case 2 is made of a transparent material which allows the operators to control the textile machines while they are functioning. In this way they can intervene quickly as soon as there is a problem, for example when the bobbins of yarn are running out.
  • a transparent material suitable for this purpose is polycarbonate inasmuch as it maintains its transparent characteristics for a long time.
  • Case 2 is also equipped with entrance openings 6 and exit openings 8 to cause the air to circulate on the inside of the said case.
  • Air entrance openings 6 are equipped with silencers 7.
  • Air exit openings 8 instead of being realised on one of the walls of the case, may also be realised in the cement base on which the textile machine is mounted, as shown in figure 1.
  • the exit openings 8 are connected by means of a system of tubes 10 and a suction pump 12 which serves to take up the air on the inside of the case.
  • the suction pump is connected beyond, by tube 14, to a filter 16 which eliminates the impurities present in the air arriving from the case 2.
  • the air purified by the filter 16 passing through a second tube 18 is expelled to the external environment by means of air exit holes 20 realised in said second tube.
  • the device 1 is furthermore equipped with means for lifting case 2 with respect to textile machine 4 in order to allow said operators to carry out maintenance operations and substitution of the yarn bobbins.
  • the lifting means are constituted by a frame 22 which is formed by two vertical rods 24 united at the top by a horizontal transverse 26.
  • a couple of pulleys 28, 30 are fixed rotatably to the transverse 26.
  • At the inside of the case a second pair of pulleys 28 and 32 are fixed rotatably.
  • Around the pulleys 28 and 32 and around pulleys 30 and 34 means 36 and 38 are arranged respectively for the transmission of the movement between the pulleys.
  • These transmission means may be constitued by transmission belts or chains which are indicated in the drawing simply by a broken line. If transmission chains are used, the pulleys 28, 30, 32 and 34 will be toothed wheels.
  • the case 2 is fixed to the forward or return run of transmission means 36, 38 in order to be raised or lowered with respect to machine 4.
  • the pulleys 28, 30 are driven by motor means which are not illustated and can be constituted for example by an electric motor.
  • the lifting means may also be constituted by hydropneumatic pistons.
  • Figure 2 represents a second form of embodiment of the invention similar to the first one, so that identical numbers represent the same parts to those represented in the form of embodiment of figure 1.
  • the device of figure 2 differs from the one described hereinbefore in that the air exit holes are connected to the air entrance opening 6 on case 2 by means of flexible tubes 40. Furthermore, the filter 16 may be equipped with an air humidifier which is not illustrated.
  • case 2 is lowered by means of the lifting means in order to completely isolate the textile machine 4 from the external environment.
  • textile machine 4 may be started together with air suction pump 12.
  • the polluted air full of particles which have become detached from the yarns during working is taken up by means of pump 12 which then sends the air towards filter 16 which eliminates the dust from the air, finally the cleaned air is returned to the external environment passing subsequently along tube 18 and exit holes 20.
  • the case 2 is equipped with silencers 7 in order to prevent noise from passing to the inside of the machine room by passing through the entrance openings 6.
  • the air is humidified by means of a humidifier present on the inside of the machine room where the textile machine is contained.
  • the functioning of the second form of embodiment is identical to that of the form of embodiment 1 and is different only in that the air going out of holes 20 is conducted directly to the case by means of flexible tubes 40.
  • this form of embodiment avoids the need to humidify the whole machine room environment with considerable energy saving.
  • the humidifier since a closed circulation system is concerned the humidifier may be positioned on the inside of said system. In the illustrated example it has been positioned on filter 16.
  • the device has achieved the proposed objectives. In fact, it prevents the dispersion of noise and polluted air inside the working environment, and in the case of the second form of embodiment, it also allows the humidity of the working environment to be reduced.
  • the device described may then be further improved by equipping it with a seal made of elastomeric material or another material suitably arranged along the perimeter of the lower base of case 2.
  • This seal when it is in the lowered position completely adhers to the base of the textile machine 4.
  • the seal prevents vibrations transmitted to the ground by the machine from being in turn transmitted to the case which in turn causes it to vibrate and so create noise.
  • the seal prevents noise created by the machine from going out of the cracks which form between the outside edge of the case and the irregularities of the base.
  • the seal also prevents the polluted air contained in the inside of the case from passing to the outside environment.
  • case 2 of the device may be provided with openings equipped with doors which allow simple maintenance of the machine or substitution of the yarn bobbins this avoiding the need to completely lift the case 2 with respect to the textile machine 4.
