Abstract
A vibrating table assembly for an apparatus for filling and weighing bulk bags comprises a bag support table, a vibrating device for vibrating the bag support table, and a lifting device for raising an lowering the bag support table, the lifting device being located below the bag support table. Preferably, the lifting device comprises a convoluted air bellows. Location of the lifting device below the table overcomes problems encountered with known bag filling apparatus where the bag support table and the lifting mechanism are connected to the frame of the apparatus.
Claims28
A table assembly for a bag filling apparatus, comprising:
- (a) a bag support table having an upper surface for at least partially supporting a bag to be filled;
- (b) at least one vibrating motor for vibrating the bag support table, the at least one vibrating motor being connected to the bag support table and being located below the upper surface of the table;
- (c) a lifting device for raising and lowering the bag support table along an axis, the lifting device being located below said bag support table;
- (d) at least one resilient connector through which the lifting device is connected to the bag support table, the at least one resilient connector damping vibrations produced by the at least one vibrating motor and transmitted from the bag support table to the lifting device;
- (e) a base plate having an upper surface on which the lifting device is mounted;
- (f) a mounting plate on which the bag support table is mounted, the mounting plate having an upper surface and a lower surface;
- and
- (g) a guide member for guiding vertical movement of the bag support table;
- wherein said guide member comprises an elongate member protruding vertically from the base and has an upper end which passes through an aperture in the mounting plate during lowering of the support table.
A table assembly for a bag filling apparatus, comprising:
- (a) a bag support table having an upper surface for at least partially supporting a bag to be filled;
- (b) at least one vibrating motor for vibrating the bag support table, the at least one vibrating motor being connected to the bag support table and being located below the upper surface of the table;
- (c) a lifting device for raising and lowering the bag support table along an axis, the lifting device being located below said bag support table;
- (d) at least one resilient connector through which the lifting device is connected to the bag support table, the at least one resilient connector damping vibrations produced by the at least one vibrating motor and transmitted from the bag support table to the lifting device;
- (e) at least one upper stop member for preventing upward movement of the bag support table beyond an upper height limit;
- (f) a mounting plate having an upper surface and a lower surface, the bag support table being mounted on the upper surface of the mounting plate;
- and
- (g) at least one bracket attached to the lower surface of the mounting plate, said bracket having a lower portion spaced from the lower surface of the mounting plate, the lower portion having an aperture sized to closely receive the upper stop member;
- wherein said upper stop member comprises an elongate member having a lower end attached to the upper surface of the base plate, the elongate member extending through the aperture in the bracket and having an enlarged upper end having an area greater than an area of the aperture, such that when the bag support table is at the upper height limit the enlarged upper end abuts the lower portion of the bracket and is located between the lower portion of the bracket and the lower surface of the mounting plate.
