Definitions

  • the invention relates to a device for filling a container open on one side with a granular substance, in particular a molding box of a mold combination with foundry molding material, with a filling container with a bottom closure.
  • a filling container For filling a container with a granular substance, in particular a molding box with foundry molding material in the production of foundry molds, a filling container is preferably used which is equipped with a bottom closure which has a plurality of flaps which can be actuated at the same time.
  • Such filling containers are charged with a metered amount of molding material according to the filling volume of the molding box.
  • the entire molding material mass simultaneously falls into the molding box below, the falling molding material mass acting as a piston-like displacer. This traps the air trapped in the molding box to the sides displaces and tears away parts of the molding material when it escapes into the environment. Air that cannot escape is enclosed by the sand mass and thus prevents a homogeneous molding material filling of the molding box, since the individual molding material particles are unevenly distributed in volume.
  • a device can be seen from DE-PS 1 758 414 (Boomer) (FIG. 4) in which a filling container has been moved via a combination of filling frame and molding box.
  • a funnel-shaped frame is placed here, which should guide the falling molding material to the filling frame.
  • the molding material mass is fed into the molding box practically without loss, but also covers a larger area than that of the molding box.
  • the air in the molding box can escape only with difficulty and thus prevents a homogeneous filling and pushes a considerable amount of molding material into the environment during the escape.
  • the discharged molding material is also a not insignificant loss factor.
  • the object of the invention is to provide a device by means of which a metered amount of a granular substance can be easily and without loss into a container without polluting the environment, the air displaced by the falling mass being discharged without interference.
  • Fig. 1 shows a vertical section through a device with a filling container which is surrounded by a container frame
  • Fig. 2 shows a vertical section through a variant, with venting arrangements used in a filling container.
  • Fig. 1 shows a simplified representation of an inventive device with possible use in a molding system.
  • the device essentially consists of a filling container 1 with an upper opening 2 and a lower opening 3.
  • the filling container 1 is provided with a funnel-shaped collar 4, while the lower opening 3 is equipped with a bottom closure 5, which consists of a plurality of actuatable flaps 6.
  • the side walls 7 of the filling container 1 widen conically from the transition to the collar 4 of the upper opening 2 towards the lower opening 3, whereby an improved measurement of a molding material mass 8 is achieved.
  • the filling container 1 encloses at a distance 10 a Sehalterrahi ⁇ en 9 connected to the filling container 1 whose inner cross-sectional area is matched to the cross-sectional area of a filling frame 11.
  • the Golfrahiaen 11 is connected to a cross-section molded box 12 which rests on a model plate 13 with model 14.
  • Filling frame 11, molding box 12 and model plate 13 together form a shape Combination in which a metered amount of the molding material mass 8 is filled for the production of the mold.
  • the distance 10 between the filling container 1 and the container frame 9 is selected in accordance with the displaceable air volume of the molding box 12.
  • the arrangement of the distance 10 means that the inner horizontal cross-sectional area of the filling container 1 is smaller than the inner horizontal cross-sectional area of the molding box 12, which means that the air displaced when the molding box 12 is filled can be measured without interference over the cross-sectional area of the distance 10.
  • Fig. 2 shows a variant with a filling container 20, the upper opening 21 also has a funnel-shaped collar 22.
  • the lower opening 23 is in turn provided with a 3ode closure 25 formed from actuatable flaps 24.
  • a bottom lock can also be used, e.g. is equipped with a slide or the like.
  • At least one tubular hollow body 26 is inserted in the filling container 20, the upper end of which is provided with a cross-section-covering shield 27.
  • the tubular hollow body 26 is advantageously designed conically narrowing towards the bottom closure in order to provide the lowest possible resistance to the falling molding material mass 8.
  • the side walls 28 of the filling container 20 are also arranged towards the bottom closure 25, conically expanding the horizontal spatial cross section of the filling container 20.
  • the tubular hollow body 26 is used approximately lying on the flaps 24 of the bottom closure 25, with which the most favorable possible outflow of the air displaced when the molding material mass is poured into the molding box 12 can be achieved.
  • the inner cross-sectional area of this filling container 20 is provided approximately equal to the cross-sectional area of the combination of filling frame 11 and molding box 12 which can be made to coincide.
  • a device according to the invention is loaded in the dosing station "A" from a dosing belt with a certain amount of molding material and then brought into the filling position "B" via the shape combination of filling frame 11, molding box 12 and model plate 13 with model 14 in the functional sequence.
  • a lifting piston 16 inserted in a lifting cylinder 15 By actuating a lifting piston 16 inserted in a lifting cylinder 15, the shape combination placed on a plate 17 is raised against the filling device 1, 9 or 20 and connected to it.
  • the molding box 12 is first lifted off from these carrying rollers 18 and guided against the filling frame 11 resting on supports 19.
  • the flaps 6 or 24 are actuated to open the bottom closure 5 or 25, so that the molding material composition 8 into the mold combination 11, 12, 13 can measure. While the molding material mass 8 is flowing out, the air in the molding combination 11, 12, 13 can escape unhindered on the one hand through the cross section of the distance 10 between the filling container 1 and the container frame 9, and on the other hand through the hollow bodies 26, 26a, without any molding material particles being released into the environment be pushed.
  • the application of the device described is not only limited to the filling of foundry mold materials, but can be used wherever granular materials in dosed amount must be filled in a container open on one side.

Abstract

Le dispositif pour le remplissage d'un réservoir (12) ouvert d'un côté avec un matériau granuleux (8), en particulier un matériau pour moules de fonderie dans un châssis de moule, comporte un récipient de remplissage (1) avec une fermeture du fond (3). La superficie intérieure horizontale du récipient de remplissage (1) délivrant le matériau granuleux est plus petite que la superficie intérieure horizontale du châssis de moule (12). Ce dispositif a pour but de laisser échapper l'air chassé par le remplissage sans difficulté et sans entraîner des particules de matériau de moulage dans le milieu ambiant. Ainsi on réalise un dosage non-polluant et sans pertes du matériau de moulage.
