Definitions

  • ABSTRACT In an installation for the mass production of bathroom pieces such as toilets and bidets, of the type utilizing mould mounts comprising two wheels rotatably mounted in two parallel vertical planes, each wheel consisting of two unequal segments of which the minor one is adapted to be removed when said wheels have been rotated for causing the major segment thereof to bear on a cradle supporting the mount and slidably mounted in the direction of he planes of said wheels on a base plate provided with rollers enabling this plate to travel on a track perpendicular to the plane of said wheels, the piston of the mould, at the piston-release station, is lifted by a fork, rotated about one of its two pairs of pivot studs and deposited as a consequence of a downward movement of the fork upon a lateral conveyor directing the assembly to a
  • a movable mount comprising two wheels rotatably mounted in two parallel vertical planes, each wheel consisting of two unequal segments of which the minor one is adapted to be removed when the set of wheels has been tipped or rotated for causing the major segment thereof to bear on a cradle supporting the mount, said cradle being slidably mounted in the direction of the planes of said wheels on a base plate provided with rollers enabling this plate to travel on a pair of rails directed at right angles to the planes of said wheels.
  • the piston after having been lifted by the fork, is rocked about one of its two pairs of pivot studs and deposited as a consequence of a downward movement of said fork upon a lateral conveyor directing this assembly to a waiting position close to the stripping station.
  • this stripping station comprises a fork engageable from beneath by the mount after overturning the two wheels by rotation on said cradle and pivoting the casting on a stripping plate, the upper portion of the mould stand supporting wheel being lifted for releasing this stand.
  • FIG. 1 illustrates the general mount arrangement, the reference numerals designating the same parts as in the above-mentioned prior Patent application;
  • FIG. 2 is a diagrammatic illustration of the general arrangement of the manufacturing installation
  • FIG. 3 is a diagrammatic view showing a mount equipped with the mould filled with slip as it registers with the mechanical piston removing device;
  • FIG. 4 illustrates the same mount engaged under the mechanical device during the operation thereof
  • FIG. 5 is a view taken in the direction of the arrows V V of FIG. 4;
  • FIG. 6 illustrates the mechanical device provided in the apparatus for removing the piston after the release of said mount and during the laying of said piston upon the lateral conveyor;
  • FIG. 7 illustrates the mount registering with the mechanical stripping device
  • FIG. 8 illustrates the mount engaged under the mechanical stripping device subsequent to a movement preliminary to the operation of this device
  • FIG. 9 is a view taken in the direction of the arrows IX-D( of FIG. 8 after the engagement of one of the pieces of the mechanical stripping device;
  • FIG. 10 is a view similar to FIG. 9 illustrating the manner in which the stand is released;
  • FIG. 11 illustrates similarly the release of the final piece by removing the lateral half-mould therefrom.
  • the mould to be used in the installation of this invention is of the type comprising essentially a piston 43, a pair of lateral half-moulds or shells 2 and a stand 16 assembled and locked to constitute an integral body for moulding an object, namely a toilet or a bidet in the specific example considered herein, and is held in a circular mount 1 according to the above-mentioned prior patent application of the Applicants. More particularly, this mount 1 comprises two vertical wheels consisting each of two unequal segments 3b, 3a adapted to be assembled as illustrated in FIG.
  • This cradle 22 supporting the two wheels is adapted either to be supported in turn by a tray 19 rolling through small wheels on rails 20, or to travel on this tray 19 in a direction at right angles to the track 20 for engaging a transverse or perpendicular clearing track (not shown in FIG. 1).
  • the complete installation illustrated in FIG. 2 comprises a pair of rails 20 forming a loop circuit track on which a plurality of such mounts 1 are adapted to travel; each mount is thus directed in succession to a casting station where the mould is filled with slip, to a draining station 31 where the excess slip is removed from the mould, to a piston release station 32 where the piston 43 is removed mechanically and laid upon a lateral conveyor 33 and driven to a waiting position adjacent a stripping station 34 where the following steps take place, namely: stripping the stand 16, moving the two half-moulds or shells 2 away from the assembly, stripping the moulded piece proper and laying same upon another lateral conveyor 35 on which it is directed to one of the finishing stations (not shown), and eventually re-positioning the piston 43 between the two half-moulds 2 and re-introducing the stand 16, so that each mount 1 thus re-equipped with a complete empty mould assembly can be directed to a drying station 36 in which the mould elements are dried, whereafter the mount 1 is recycled by being directed to
  • the casting station 30 and draining station 31 have no specific features, yet it should be emphasized that by using the mount 1 it is possible for each operation to set the mould in the optimum angular position as may be required for a particularly easy handling, consisting in rotating the two-wheel assembly on the cradle 22.
  • the piston release station 32 is connected to the main track 20 by a lateral or transverse clearance track 37.
  • a mount 1 is stopped in lateral alignment with this clearance track 37 the upper segment 3b is removed from the mount, thus eliminating the holddown pressure on piston 43.
  • the cradle 22 is transferred laterally to said clearance track 37 as shown in FIG. 4 and during this movement the two pairs of pivot studs 38, 39 projecting from opposite sides of piston 43 engage corresponding lugs 40, 41 of a fork 42. Then this fork 42 is lifted and, as shown in FIGS. 4 and 5, the studs 38, 39 and piston 43 are raised accordingly and removed from the mould assembly.
  • the mount 1 is returned to the main track 20 and piston 43 can be tipped in the direction of the arrow of FIG. 6 about the lugs of fork 42 until the rear end of this piston engages an apron 44 and the piston is deposited upon this apron as a consequence of the downward movement of fork 42.
  • the movement of apron 44 in the direction of the horizontal arrow of the Figure is attended by the deposition of said piston 43 upon the lateral transfer conveyor 33 shown in the drawing in the form of sequence of rollers, this assembly being thus driven to a waiting position adjacent the stripping station 34.
  • the mount 1 carried by track 20 and leaving the piston release station 32 is directed along the track 20 to a position in which it registers with another transverse track 54 as shown in FIG. 7, this track 54 leading to the stripping station 34.
  • the mould In the waiting position as illustrated in FIG. 7 the mould is completed with a stripping plate 17 fitting on the upper peripheral contour of the pair of lateral half-moulds or shells 2, and the remaining elements are reassembled by refitting the segments 3b on segments 3a. Then the wheels are rotated through half a revolution and the cradle 22 is transferred to the lateral track 54 as shown in FIG. 8.
  • Suitable studs or lugs 45 carried by the major segment 3a are then caused to engage the pair of arms of a fork 46 mounted in this station 34 above the transverse track 54, as shown in FIG. 9.
  • the fork 46 is subsequently lifted so that the stand 16 is raised bodily with the pair of segments 3a until said stand 16 is released completely above the two half-moulds 2 as shown in FIG. 10.
  • the two half-moulds 2 are subsequently moved away as shown in FIG. 11, by causing them to bear on side brackets 47 provided in station 34 on either side of the transverse track 54, so that the casting or moulded piece 48 can eventually be removed and deposited upon the lateral conveyor 35 which directs it to the other finishing stations.
  • the piston 43 in a waiting position at the end of conveyor 33 is then picked up by the oncoming fork 46 and replaced in its central position with respect to the wheel.
  • the two half-moulds or shells 2 are folded back against the piston sides and the stand 16 is finally lowered between the two half-moulds or shells 2.
  • said piston release'station comprises a fork under which the mount is engaged after releasing its upper segments, said fork mounted to pick up the studs of said piston, so that the latter is lifted to free the lower elements of the mould.
  • the stripping station comprises a fork under which the mount is engaged after tipping the two wheels by rotation on said cradle by causing the casting to bear on a stripping plate and lifting the upper portion of the wheel supporting the mould stand by releasing said stand.
