Definitions

  • the present invention relates to transporting devices.
  • the present invention relates to a device for transporting pourable goods such as liquids or solids in bulk.
  • the invention relates particularly to that type of device where the goods are contained within a silo-type of container made of a foldable sheet material which is suspended from a frame such as a steel frame.
  • Transporting devices of this general type are known.
  • the container for the goods is fixed at a plurality of locations to the steel frame.
  • Such containers have proved, in practice, however to be particularly prone to damage during transport, especially when the transporting vehicle is abruptly braked. Under these conditions the container is likely to burst, especially during an extreme change in acceleration or deceleration.
  • the device includes a container means made of a folable sheet material and adapted to contain the pourable goods which may take the form of a liquid or a solid in bulk.
  • the container means has upper and lower end regions, and a frame means is operatively connected with the upper end region of the container means so as to carry the latter with the container means suspended from the frame means.
  • a guide means is operatively connected to the lower end region of the container means to guide the lower end region for movement in a given direction which preferably is the direction of travel of the device during transport thereof.
  • the container means is made in one piece of a sheet material, especially a woven fabric which may be coated with plastic.
  • the guide means at the lower end region of the container means is preferably operatively connected with the frame means for shifting movement with respect thereto, this guide means is particular taking the form of a pin-and-slot connection with the frame means.
  • FIG. 1 is a fragmentary partly sectional schematic elevation of the symmetrically constructed container means and part of the frame means to which it is connected, the sectional illustration, particularly at the lower portion of FIG. 1, being taken in a plane which is perpendicular to the predetermined direction in which the guide means guides the lower end region of the container means for movement;
  • FIG. 2 is a schematic perspective illustration of the frame means
  • FIG. 3 is a schematic front elevation of the foldable container means
  • FIG. 4 is a fragmentary sectional elevation illustrating the manner in which the upper central region of the container means is connected with the frame means;
  • FIG. 5 is a fragmentary schematic sectional elevation illustrating the manner in which an upper peripheral region of the container means is connected with the frame means;
  • FIG. 6 is a schematic fragmentary sectional elevation illustrating the manner in which a lower central region of the container means is connected with the frame means;
  • FIG. 7 is a fragmentary schematic elevation showing in section, in a plane parallel to the direction of movement provided by the guide means, the details of the structure at the lower region of the container means from which the goods is discharged.
  • the container means 1 is provided at its upper end region with extensions 2, and it is by way of these extensions 2 that the container means is fixed to and suspended from the illustrated frame means formed by the steel frame 3.
  • the lower end region of the container means 1 forms the discharge end for the goods situated within the container means 1 and has the configuration of a discharge funnel 6 which is tapered as illustrated.
  • the freely swingable lower end region of the container means 1 is operatively connected with the frame means 3 by a guide means 14 which guides the lower end region 6 of the container means 1 for movement in a predetermined direction with respect to the frame means 3. This latter direction is preferably the same as the direction of travel of the device of the invention.
  • the guide means 14 has the construction of a pin-and-slot connection between the lower end region of the container means I and the frame means 3.
  • the bottom end of the container means 1 is fixed with a pair of elongated side flanges which extend perpendicularly to the plane of FIG. 1 and which are formed with elongated slots.
  • These side flanges rest upon elongated bottom frame members 21 of the frame means 3.
  • These frame members 21 extend perpendicularly to the plane of FIG. I and are preferably arranged in the direction of travel.
  • the members 21 fixedly carry bolts 23 which extend upwardly through the slots in the side flanges of the guide means 14 so that in this way the pin-and-slot connection which forms the guide means is provided.
  • These bolts carry nuts which can be tightened to a predetermined extent for forming a means for adjusting the frictional engagement between the guide means 14 and the frame means 3 so that in this way the extent to which movement of the bottom end of the container means is frictionally resisted can be adjusted.
  • a spring structure to form shock absorbers at the bottom end of the container means, to absorb any shocks in connection with movement provided by way of the guide means 14.
  • This discharge structure may include a slidable valve plate shown in its closed position in FIG. 1 and capable of being shifted to an open position for releasing the goods out of the container means 1.
  • the discharge structure may have, as shown in FIG. 7 and described in greater detail below, connections 28 for pneumatic or electro-mechanical conveyer structure used to convey the goods away from the container means 1 during discharge of the goods out of the latter.
  • the container means 1 has a top inlet opening 11 through which the goods is introduced into the container means 1.

  • This inner ring 8 is surrounded by a clamping ring or collar 9 of the clamping means 8, 9.
  • an extension 2 of the top wall 7 of the container means is clamped directly to the frame means by way of the clamping means 8, 9 shown in FIG. 4.
  • the portion of the central upper extension 2 which is folded back upon itself surrounds a reinforcing ring 10 in the form of a cable or metal ring situated in th hem which is formed by the folded back portion of the fabric which forms the extension 2 shown in FIG. 1.
  • this ring 10 inserted in and surrounded by the extension 2 is situated directly over the clamping ring 9 which does not have a diameter greater than the reinforcing ring 10, so that downward slipping of the container means 1 with respect to the clamping ring 9 is prevented.
  • a further securing of the container means 1 to the frame means 3 is achieved by welding the bottom edge of the ring 8 an additional ring 16 which also'has an outer diameter substantially equal to the outer diameter of the ring 9 when the latter is in its clamping position shown in FIG. 4, so that by way of this circular ring 16 downward slipping of the clamping ring 9 is prevented.
  • This clamping ring 9 is in the form of a circular ring having a pair of adjoining ends provided with outwardly directed flanges located directly next to each other and capable of being bolted together for releasably holding the clamping ring 9 in its clamped position shown in FIG. 4, one of the flanges at one of the ends of the ring 9 being apparent from FIG. 4 extending from the left of the remainder of the ring 9.
  • a closure in the form of a steel closing plate 13 is provided over the filling opening 11 of the container means 1.

  • the frame means 3 is provided with elongated bars 18 which define the upper edges at the periphery of the top wall of the frame means 3, and the supporting ring 17 is fixed, as by welding, directly to the central regions of each of the upper bars 18 forming the upper edges of the frame means 3.
  • the ring 17 from which the container means 1 is directly supported is itself supported by the frame means 3 at the upper edge regions 18 thereof.
  • These reinforcing bars 19 are fixed at their ends, as by welding, to the bars 18, and the ring l7 may additionally be fixed to central regions of the reinforcing bars 19.
