Definitions

  • ABSTRACT The invention provides systems for opening and closing access apertures in the outer walls of tannery pad dle tumblers and the like.
  • the system consists of a door which is slid in guides, the movement of the door being controlled by a fluid motor and fluid control. The movement of the door is efiected by the fluid motor which moves a rack attached to the door. Means for providing a seal between the door and the access aperture are also described.
  • the present invention provides a mechanized opening system for a door of a tannery paddle tumbler or the like comprising sliding guide means for the door and a fluid control to slide said door along said guide means between an open position and a closed position and vice versa including a rack control and a fluid motor.
  • the present invention generally permits the manual operations required with such tumblers and the like to be reduced and such operations as are effected to be combined with increased machine production output. Furthermore, a good seal between the door and the rotatable container can be provided for easy discharge of the contents to be effected.
  • sliding guide means for a door structure are provided with fluid control to slide the door along the said guides between an opening position and a closing position and vice versa.
  • the fluid (hydraulic or preferably pneumatic) control can be operated from a stationary position through manifold means.
  • Control of the opening system according to the invention is effected by means of a rack and a fluid motor, the rack preferably being integral with the door and the fluid motor with a meshing pinion carried on the paddle tumbler wall.
  • the door sliding guides are provided in planes normal to the rotational axis of the tumbler and they are generally arcuate around the generally circular profile of the rotor section.
  • the corresponding rack or racks are also arcuate, said racks extending on and/or from the door panel to mesh with the pinion or pinions operated by the fluid motor.
  • a resilient packing such as an inflatable enclosure wherein a pressurized fluid may be fed to deform the packing and press it against the inner surface of the door (slidable on the outside of the tubular wall) when the door is in the closed position.
  • a pressurized fluid may be fed to deform the packing and press it against the inner surface of the door (slidable on the outside of the tubular wall) when the door is in the closed position.
  • supports 1 and 3 serve to hold a rotor 5 for rotation, the rotor being in the form of a paddle tumbler for a tannery.
  • 5A indicates one hub of the rotor S for support in rotation.
  • a motor or drive unit for tumbler rotation is indicated generically at 7.
  • An opening 9 in the cylindrical wall of the tumbler is provided with an edge or rim 9A which forms a seat for an annular inflatable packing or gasket 1 l which is provided for the hereinafter described purposes.
  • An arcuate panel 13 forming the closing door is the same shape as the tumbler wall and it may slide along arcuate guides 15 fixed onto the outside of the tumbler wall.
  • the sliding of the door 13 along the guides 15 is obtained with the aid of an arcuate rack 17 integral with the door 13 and of a geared pinion l9 meshing therewith and operated by a fluid motor 21 attached to the tumbler wall and fed with fluid in the hereinafter described manner.
  • a fluid motor 21 attached to the tumbler wall and fed with fluid in the hereinafter described manner.
  • a fluid for instance air
  • the door 13 may be moved by the system of operating parts indicated by the reference numerals 21, 19 and 17 into the closed position (FIG. 5)
  • a fluid for instance air
  • the door may be retained in the closed position (and also the open position) by maintaining the fluid feed to the motor so as to force the door against the attained position.
  • a member 22 attached to the hub 5A forms the movable portion of a manifold.
  • the channels follow the structure of the rotor and they are provided in a sufficient number to allow the desired control operations to be provided.
  • the rotary member 22 attached to the tumbler is surrounded by a member 29, to which are connected channels 31 fed with fluid, for instance from a power unit.
  • the interior of the member 22 and of the hub 5A can be axially hollow for additional purposes.
  • the operation of the motor 21 can also be controlled by limit switches, for example those indicated at 35,
  • FIG. 7 an embodiment is shown including two racks 43 on the panel 41 of the cover which mesh with coaxial pinions 45 operated by a motor 47.
  • the described arrangement may be provided with locking means for the panel, for example a hydraulic or pneumatic latch or the like.
  • a locking effect may also be provided using the same fluid motor as is used to open the panel.
  • a tannery paddle tumbler or the like comprising a generally cylindrical rotatable member having an opening formed in the peripheral wall thereof for gaining access to the interior of the tumbler, arcuate guide means mounted on the outer wall of the tumbler adjacent said opening, an arcuate closure member, means for opening and closing movement of said closure member along said arcuate guide means including an arcuate rack attached to the outer surface of said closure member and a motor-driven pinion meshing with said rack and mounted on the outer wall of the tumbler a fluid inflatable elastic gasket around the periphery of the opening in the wall of the tumbler forming a resilient seal between said closure member and the wall of the tumbler, a fluid motor for driving said pinion, and means for introducing fluid from a common source to said motor and to said seal.
  • said means for introducing fluid includes an axially extending hub and a member rotatable about said hub defining a plurality of annular grooves through which fluid is permitted to flow in a selective manner.
  • a tannery paddle tumbler or the like comprising a generally cylindrical rotatable member having an opening formed in the peripheral wall thereof for gaining access to the interior of the tumbler, arcuate guide means mounted on the outer wall of the tumbler adjacent said opening, an arcuate closure member, means for moving said closure member along said arcuate guide means for opening and closing said opening, said moving means comprising an arcuate rack attached to the outer surface of said closure member and a motor driven pinion meshing with said rack and mounted on the outer wall of the tumbler, a fluid inflatable elastic gasket around the periphery of the opening in the wall of the tumbler forming a resilient seal between said closure member and the wall of the tumbler, a fluid motor for driving said pinion, an axially extending hub, a rotary member attached to said hub having a plurality of annular grooves formed therein and channels causing selective communication between whereby fluid can be introduced to said gasket and to said motor, and an enclosure member surrounding said rotary member having radial openings therein for re?
