Definitions

  • the present invention relates to a device for facilitating the handling of objects such as large capacity bags filled with a wide variety of materials: for example, but not limited to, bags of powdered or granular products such as those described in French patent 2,564,440.
  • the bags which are to be handled are generally provided with belts. Stras, handles or suspenders used to attach the hooks to hoists, cranes or other handling equipment. This requires the intervention of an agent, other than the one who drives the handling machine, or, if it is the same, he must get off his machine.
  • the invention relates more particularly to the handling of such bags by forklifts.
  • the driver may not engage the forks in the bag gripping straps without the assistance of an auxiliary, or without getting off his station. if you place the forks under the bag, you risk overturning it
  • Patent application GB A 2 150 538 which corresponds to the preamble of claim 1, describes an equipment comprising four metallic elements, two long elements joined in scale by two short elements. The latter are fitted with hooks for hanging the straps of a bag. One can pass under the long elements the teeth of a forklift, to lift said equipment with the bag.
  • the present invention relates to a device for gripping bags by a forklift, without any intervention from the driver, in much better conditions.
  • the present invention relates to a device for handling large capacity bags filled with pulverulent or granulated materials, provided with straps for lifting them, comprising a rigid element of generally substantially flat shape comprising in its thickness at least four bars with means for hanging the straps and leaving between them a surface allowing normal filling of a bag, characterized in that comprises four tubes arranged in a square and intersecting two by two, their ends projecting from the square.
  • the tubes are open at their two ends so as to be able to receive the teeth of a forklift while leaving between them sufficient surface to allow normal filling of a bag, the length of the opening between two parallel bars being appreciably greater than the lengths of the two bars added together.
  • the surface of the rigid planar element will correspond substantially to the horizontal section of a bag to be lifted apart from the ends of the tubes which protrude to ensure secure attachment.
  • the rigid element is associated with a rigid toroid-shaped accessory whose outside diameter is slightly less than that of the central opening of said rigid element, a latching means being provided for allow said accessory to be kept inscribed in said central opening of said rigid element.
  • torus is understood here to mean a "surface of revolution generated by a curve which turns around an axis situated in its plane and not passing through its center". Said torus is a priori arbitrary, but is advantageously open, that is to say such that said curve is not closed, thus being able, for example, to form by turning a circular gutter -annular- with substantially concentric edges, and of different diameters. This latter configuration has, among other advantages, that of being able to stack such accessories one inside the other. We will see later how this can be interesting in the use of the device of the invention.
  • Said accessory is intended to facilitate the filling and emptying operations of a bag of the type described above and provided in its upper part with a flexible chute in the form of a sleeve, said sleeve extending from the upper edge of the bag. , between its straps, and ending with an advantageously circular opening, with a diameter slightly greater than the inside diameter of the central opening of said accessory in the form of an annular gutter.
  • Said latching means may comprise a groove or a recess provided circumferentially on the radially outer part of said accessory, and cooperating with protuberances in the form of bumps formed on the inner part of said element and extending radially inwards.
  • said accessory has substantially the same height as said rigid element, and practically does not protrude therefrom when it is in place, inscribed in the central opening of said rigid element.
  • flexible containers or bags 1 of the type shown in FIG. 1 are used to move, store, evacuate, etc., all kinds of powdery or granular products such as earth, sand, gravel , fertilizers, chemicals, seeds, etc.
  • These bags have gripping straps 2, 3, 4, 5, in which crane hooks, forklift trolleys, etc. can be passed.
  • a square forcing 6 having the shape of four tubes 11, 12, 13, 14, of rectangular section arranged in a square in the same plane, orthogonal to each other .
  • the tubes extend so that their ends 7, 8 (FIG. 3) extend the sides of the square beyond the vertices, so as to form cross-shaped nuts 9 depending on the square by zones 10 of narrow section ( Figure 3) so as to constitute an attachment zone.
  • the dimensions of the square 6 correspond substantially to the horizontal dimensions of the bag 1.
  • the tubular sides of the square are released from one end to the other on each side and open at the two ends.
  • the device of the invention is used in the following manner. Place the square 6 on top of a filled bag, and pass the straps 2, 3, 4, 5, over the braces 9, in the throttles 10, as shown in Figure 2. It is then simple to engage in the tubes 11 and 13, or 12 and 14, by one end or the other, the forks of a handling carriage, the spacing of which has been previously adjusted appropriately. The bag can then be conveniently handled by the operator, without having to get out of his cart, and without the assistance of any other person.
  • Figure 5 shows in plan another embodiment of a square with braces according to the present invention.
  • the device of the invention can be made of any suitable material: metal wood, plastic.
  • the latter having the advantage of low cost price.
  • the material of the spider practically does not work in operation. Only the upper part of the throttle 10 is stressed in compression between the strap 2, 3, 4, 5, and the fork of the carriage engaged inside the tube 11, 12, 13, 14, constitutive.
  • the lower surface of the brace does not support any effort during the handling of the bag (the upper part and the lower part are identical, the brace having neither above nor below, to maintain the simple use).
  • the lower part with the sides is mainly used for guiding the forks and assists in keeping them in place correctly during handling.
  • the handling device has at least two parallel tubular conduits, and the square shape with four tubes is very suitable. A shape with 6 or more sides would not bring any appreciable advantage, and would complicate the manufacture.
  • FIGs 6, 7 and 8 is illustrated another embodiment of the present invention.
  • a rigid element 16 resembling that shown in Figure 5, but further comprising four elongated bumps 17 provided substantially in the middle of the inner side faces of said tubes arranged in a square, a bump on each tube. The large dimension of each bump is aligned with the longitudinal axes of said tubes.
  • a rigid accessory 18 in the form of an annular gutter open upwards and with concentric edges can be snapped into the central opening of said rigid element 16 by means of a groove or a recess 19 provided circumferentially on the external part of said accessory, and cooperating with said elongated bumps formed on the internal part of said rigid element.
  • To snap said accessory into said element it suffices to present it axially above said element and to force it into it.
  • a bag 20 provided with a chute 21 is suspended by its straps 4, 5 from the arms 22 of a lift truck - not shown in the figure - by means of a rigid element 16 as described above with reference to Figures 6, 7 and 8.
  • a first and a second rigid accessories 18 ⁇ and 18 ⁇ both identical to that described with reference to the same figures.
  • the two accessories 18 ⁇ and 18 ⁇ are engaged one inside the other, and wedge between them the upper edge of the chute 21. This greatly facilitates the filling of the bag 20 with material 23.
  • the device of the invention promotes stacking or "stacking" of the bags; it suffices to leave said rigid element in the straps of the bag.
