Definitions

  • Th1s mventlon relates to an lmprovernent in devices [51] Int. C1. B65g51/02 for transportmg Oblects Over long dstances by [58] Field Of Search 243/25-28 quizzed Particularly in inject members having a 243/38.
  • induced air devices comprising at least one injector member having the section of a Venturi tube.
  • this device does not always ensure a satisfactory guiding of the different objects which are desired to be transported and which may have different shapes and volumes.
  • the present invention has mainly for its object guide means which are disposed in particular in the injector member and which facilitate the rational transport of all objects such as bottles, flasks, boxes, tubes, balls,
  • a means for guiding the objects constituted by a slide whose shape is adapted to the section of the objects to be transported, and which extends over the whole of the length of the injector member, beingconstututed by a conduit having, at least in a part of its wall, openings communicating the inside of said conduit with the air flowing in the injector member.
  • a conduit having, at least in a part of its wall, openings communicating the inside of said conduit with the air flowing in the injector member.
  • opposite the outlet aperture of the injector member is disposed at deflectormember unitary with a sleeve capable of being displaced for adjusting the output. This sleeve adjusting the air output enables a maximum yield to be obtained at aspiration without affecting the long-distance transport, as a function of the distance, the weight of the object and the rhythm of transport.
  • FIG. 1 is a longitudinal section through the injector member of an object transporting device, provided with a means for guiding the objects.
  • FIG. 2 is a longitudinal section through an injector member provided with a different guide means.
  • FIG. 1 an injector member 1 with a section in the form of a Venturi tube is shown, which forms part'of a device for transporting objects by induced air, said injector member being connected to a conduit 2 for the inlet of pressurised air, and to a transport pipe 3 placed at the outlet of the injector member.
  • a nozzle 4 comprising an aperture 5 for the intro
  • This slide 6 whose section is adapted to the section of the object to be transported, ensures the guiding of the objects between the input nozzle 4 and the transport pipe 3.
  • a material is used which is adapted to the problem of transport, particularly stainless steel, black sheets, aluminum, plastics material.
  • the slide 6 is limited to the part of the injector member corresponding to the outlet cone 1a and it stops at the injection cone lb.
  • the length of the slide 6 is established as a function of the fragility of the objects to be transported.
  • a sleeve 9 mounted to slide on the tube 3 or on the outlet piece 11, has a deflector member 10 disposed opposite the outlet aperture 11 of the injector member 1, said deflector member being able to occupy positions 10a, 10b, 100, for which it is more or less close to the aperture 11 of the injector member so as to regulate the output of air.
  • said conduit may be constituted of a perforated tube or another conduit having air outlet apertures.
  • a device for transporting objects over long distances by induced air having injector members having a section in the form of a Venturi tube and comprising slide means for guiding the objects through the tube disposed inside the injector member, said slide being a conduit having a shape conforming to that of the said objects and extending over the whole length of the injector, said slide having a wall with openings in at least a part thereof which connect the inside of said conduit with air flowing in the injector member.
  • the guiding slide is constituted by a bundle of separate rods disposed longitudinally inside the injector member, according to a determined profile.
  • conduit presents said openings only in a limited part of its length located opposite the part of the injector member outside the injection cone.
  • the improved injector comprising a tubular member having a longitudinal axis which is in substantially the same plane as the longitudinal axis of the conveyor tube and is disposed with one' end thereof adjacent an end of the conveyor tube, a Venturi in the injector tube diverging towards the conveyor tube, means for introducing material to be conveyed into the injector tube upstream of the Venturi, means for guiding the said introduced material through the Venturi and into the conveyor tube, said guiding means having a longitudinal axis common with those of tube upstream of the Venturi and through the perforated wall into the guiding means.
  • the pneumatic conveyor of claim 6 wherein the said guide means is cylindrical and the perforated wall 9.
  • the pneumatic conveyor of claim 7 wherein the is a plurality of circumferentially spaced longitudinally guide means extends from adjacent the part of the inextending members. jector where material to be conveyed is introduced 8.
  • the pneumatic conveyor of claim 7 wherein the through the Venturi into the said end of the conveyor guide means extends from just downstream of the Ventube.
