Definitions

  • the present invention relates to a packing or tamping arrangement.
  • the present invention relates to a tamping apparatus for tamping powdered material into a metallic sheathed cable composed of a central conductor and a sheath surrounding the same.
  • the objects of the present invention also include the provision of a tamping or packing arrangement which is of very simple construction and incorporates very few parts so that the apparatus may be built, operated and maintained at very low cost.
  • the present invention mainly consists in that improvement in a packing or tamping apparatus which comprises a support, a tubular packing member having a free end face and mounted on the support for reciprocating movement relative thereto in axial direction between an operative position wherein the end face engages a material to be packed and an inoperative position spaced therefrom material supply means in communication with the packing member for conveying the material to be packed to the interior thereof, closure means operatively associated with the packing member for movement therewith while the latter moves between its operative and inoperative positions and for movement relative to the packing member between a closed position wherein the closure means closes the packing member in the region of the end face thereof and an open position spaced from the closed position, and operating means for holding the closure means in its open position when the packing member is in its inoperative position, for moving the closure means to its closed position during movement of the packing member from its inoperative position to an intermediate position intermediate the operative and inoperative positions, and for maintaining the closure means in its closed position during movement of the packing member from its intermediate position to
  • Fig. l is an assembly view of this apparatus
  • Figs. 2 and 3 are respectively sections of upper and lower portions of the apparatus on a larger scale
  • Figs. 4 to 8 are diagrammatic representations of various positions of the apparatus during operation thereof.
  • the distribution and compression element is constituted by a hollow tamper or packing element 3, the end of which is open and carries a seat 5 on which a valve 6 may bear.
  • the valve 6 acts as a closure means for closing the tamper 3 in the region of its lowermost end face.
  • the valve seat 5 thus constitutes the lower or free end of the tamper 3, and this free end when the tamper is axially reciprocated will engage and exert downward pressure upon a powdered material to be tamped or packed as will be further described.
  • the latter is carried by and movable with a control tube 4.
  • Wings 7, associated with the valve 6, ensure the centering of the latter inside the hollow tamper, and the tamper and valve are arranged in the annular space formed between a tight tubular sheath 1 and by a central conductor 2 which together form a sheath and conductor assembly.
  • An eccentric actuator member 8 imparts to the tamper 3, 5, a reciprocating motion along the axis of the assembly.
  • the tube 4 carrying the valve also carries a cross piece 9 which is pushed upwards by a spring 10 bearing on a stop 11 which is mounted on the hollow tamper 3 and held by a set screw 11a or the like.
  • the cross piece 9 carries a pair of adjustable abutment screws 12 which are adapted to engage a stationary abutment 13 carried by the housing of the driving mechanism.
  • the housing represents a supporting structure or support for the driving mechanism for the tamper 3 so that in this way the tamper is mounted on said support for reciprocating movement relative thereto in axial direction.
  • this movement is between an upper operative position wherein the lower or free end of the tamper engages and exerts downward pressure upon a material to be packed and an inoperative position in which the tamper is disengaged and spaced from the material.
  • the sheath and conductor assembly 1, 2 rests on a base or carrier 15 through a pedestal plate 22 and springs 21.
  • the base itself is suspended from cables 23 which pass over pulleys 24 and are tensioned by counter-weights 16.
  • the mass of these counter-weights is such that they tend to move the base upwards.
  • This action is prevented by ratchet wheels 17 associated with the pulleys 24, so that when the base 15 is subjected to the thrust of the tamper 3 through the powdered material, the base can move downwardly during a downward stroke of the tamper.
  • the pawls cooperating with the ratchet wheels prevent upward movement of the base.
  • the sheath and conductor assembly 1, 2 is further held vertical by a guide 19.
  • a motor 18 rotates the eccentric actuator member 8.
  • a tubing 20 makes it possible for the powdered material to be introduced into the hollow tamper 3.
  • the apparatus operates as follows:
  • Powdered material is introduced into the material supply tubing 20 which is in communication with the interior of the tamper 3.
  • the material remains in the interior of this tamper as long as the valve 6 is urged against its seat 5 by the action of the spring 10.
  • the rotation of the eccentric actuator member has the efiect of reciprocating the tamper 3, and Figs. 4 to 8 illustrate the various positions of the tamper 3 and the valve 6 during one cycle of operation.
  • Fig. 4 shows the tamper 3 in its lowermost operative position in which the bottom end face of the tamper is in engagement with a mass of powder that has just been tamped.
  • Fig. 4 further shows the valve 6 in its closed position in which it closes this bottom end face of the tamper.
  • valve 6 will be carried along inasmuch as the spring 1t which is interposed between the ring 11 carried by the tamper 3 and the cross piece 9 carried by the tube 4 will continue to act in such a manner as to maintain the valve 6 in engagement with the valve seat 5. That is to say, the spring 10 will constantly urge the valve 6 into engagement with the valve seat irrespective of the axial position of the tamper 3, and Fig. 5 shows the tamper 3 in an intermediate position in which it is spaced from the operative position, i.e., in which the end face 5 is spaced from the mass of previously tamped powder. It will be seen that while the tamper is in its intermediate position, the valve 6 is still in its closed position.
  • valve 6 Upon continued reciprocation of the tamper 3, it will commence its downward movement until the Valve seat 5 reaches the valve 6. Thus, as soon as the tamper again reaches its intermediate position, the valve 6 will be closed (Fig. 7), and during continued downward movement of the tamper 3 from this intermediate position to the operative position shown in Fig. 8, the valve 6 will remain closed.
  • a vibrator device 14 may be provided on the base 15 for vibrating the same and consequently for vibrating the material to be packed in the assembly 1, 2 during operation of the apparatus.
  • the downward face received by the tamper 3 is transmitted by the material to the pedestal plate 22 then through springs 21 suitable loaded, to the base 15.
  • this face is sufficient for overcoming the action of the counter-weights 16, the sheath and conductor assembly 1, 2 moves downwardly under the action of the tamper and becomes fixed in the position corresponding to the end of the run of the tamper 3 owing to the ratchet wheels 17.
  • the present invention is not limited to apparatus of the type described above. It is possible, without departing from the scope of the present invention, to use apparatus of the same type in which the rough 1, 2, is placed in an inclined or even a horizontal position. It is sufficient, then, to merely provide means for feeding the powdered material up to the valve 6.
