  • This invention relates to presses for compressing granular material mixed with a binder into solid blocks, especially electrode blocks. More particularly the invention concerns a press using a mold open above and below, operating together with upper and lower compression or stamping members. ln this type of press the mold and one or both compression members are movably mounted in the press frame.
  • the capacity of the known types of presses is limited, because the individual operations, particularly the measuring out of the material, the charging of the mold and the pressing of the material into a block follow in succession. In order to increase capacity, therefore, a number of presses are used. It is also known to break down the operations into stages accomplished with different equipment in which case, for example, precompression is performed in one equipment and final compression in another. The expense of such operations is, however, relatively large and for that reason they are economical only in particularly exacting applications. It is an object of the invention to provide a press for compressing granular material into blocks which is capable of providing a substantial increase of capacity. It is desirable to use a time of compression that is as long as possible, since that reduces the drive power that is necessary. A relatively long compression period is also desirable from a process engineering standpoint, because plastic deformation of the material under compression can then proceed more effectively and uniform density of the block can be obtained.
  • a laterally movable charging container that has an openable wall provided with a piston drive by which that wall can be held closed and by which it can be brought into open position.
  • the pressing operation can already begin before the charging container has been removed from the compression site and, nevertheless, the next charging operation can be prepared during pressing of a block.
  • the charging container is open above and below and its bottom slides over a surface flush with the top end of the mold, so that at the outer end of its lateral movement, where it is resting on a bracket attached to the mold, it is loaded by material dumped into it from above by a dosage device and guided by a sleeve that encloses the loading path.
  • the sleeve is extended into position before loading in order to allow for downward movement of the charging container and its support bracket resulting from reaction of the mold to the power stroke of the movable plunger of the press.
  • the charging container moves .per is provided on the exterior of the charging container for that operation.
  • the movements of the mold, the movable compression member or members, the charging container and its movable wall, as well as the discharge of the dosage device and the extension of the guide conduit sleeve are preferably all driven and synchronized by hydraulic piston drives.
  • FIGS. 1 to 4, inclusive, are vertical sections, partly in elevation, of a diagrammatically represented press in accordance with the invention, respectively showing the press at various stages of operation in a single operation cycle;
  • FIG. is a top view of the charging container of a press according to the invention provided with an openable wall actuated by means of piston drives.
  • a movable mold 2 In FIGS. 1 to 4, inclusive, a movable mold 2, a fixed lower compression member or anvil 3 and an upper movable compression member or ram 4 are mounted on a diagrammatically represented press frame 1.
  • the compression member 4 is a part of a press piston 6 protruding into a press cylinder 5.
  • the pressure medium (which may be hydraulic) can enter or leave the cylinder 5 through a passage 7.
  • On both sides of the press cylinder 5 are rapid motion cylinders 8 for providing the necessary quick return motion.
  • the pistons of these rapid motion cylinders are provided with piston rods 9 affixed to a cross piece 10 mounted on the movable compression member 4.
  • the rapid motion piston drives 8,9 are reversible, whereas the main cylinder 5 and the press piston 6 provide a single acting or one-way piston drive.
  • Another pair of piston drives 14 is provided at the base of the press frame 1. These drives move the mold 2.
  • a bracket 15 is affixed to the mold 2 for support of the charging container 16 that is arranged to slide horizontally on the upper surface of the bracket and the mold, as driven by a piston drive 17.
  • the charging container 16 At one end of its travel the charging container 16 is in the middle of the press, whereas at the other end of its travel it is located under a dosage device collectively designated 18 that measures out the filling material.
  • the granular material is supplied over a conveyor belt 19 and a conveyor chute 20 which may, for example, be an oscillating chute, by which it is delivered to a weighing container 21.
  • the charge for the next compression step is prepared and weighed by means of a scale 22.
  • Piston drives 23 are provided on the weighing container 21 for raising and lowering a guide conduit.
  • the guide conduit 24, in the form of a vertical sleeve, serves to provide a closed connection from the weighing container to the charging container 16, so that when the trap door that forms the floor of the weighing container 21 is opened the entire charge of material is dumped into the charging container without loss.
  • the charging container 16 has one wall 25 that can be moved out of the way by means of piston drives 27 as described with reference to FIG. 5.
  • FIG. 5 the charging container 16 is represented as seen from above.
  • the piston drive 17 acts by means of a plate 28 fixed on the charging container 16.
  • the latter is slidably mounted by means of guide bushings 30 on guide rods 29.
  • the wall 25 of the charging container consists of two flaps, or door leaves, mounted to swing on hinges 31.
  • Each of the two piston drives 27 grips a lever 32 connected with one of the flaps of the wall 25.
  • the flaps of the wall 25 are swung in the direction of the two arrows until they reach the position shown in broken lines, at which point this side of the charging container is fully open.
  • On the outside of the flaps of the wall 25 are respectively located two bumpers 33 by means of which a block completely pressed in the previous operation can be pushed on to a roller conveyor 35 adjacent to the press, when the charging container 16 is moved into the press.
  • the press In FIG. 1 the press is in its normal or idle position, i.e. the mold 2 is fully depressed and the end plate 36 of the lower compression member 3 is flush with the end surface of the mold 2 and with the support surface surface of the bracket 15.
  • the movable upper compression member 4 is in its highest position.
  • the charging con tainer 16 is filled with a charge of material to be compressed.
  • the flaps of the openable wall 25 of the charging container 16 are closed and the bumpers 33 are in position for knocking the completed block 37 out of the press.
  • the bottom (not shown) of the weighing container 21 is closed and the scale 22 is measuring the weight of the material flowing over the chute 20 as it pours in.
  • the completed block 37 pressed in a previous cycle of operation stands ready to be knocked on to the roller chute 35.
  • the filled charging container 16 now begins to travel into the space between the two compression members 3 and 4, and at the same time oil nozzles 38 provided in the charging container spray a lubrication oil mist on the faces of the respective compression plates 12 and 36 in order to prevent adhering of the block to the same.
  • the bumpers 33 push the block 37 until the charging container 16 has reached the middle of the press.
  • the mold 2 is now raised, raising with it the bracket and the charging container 16, so that the charging container can now empty itself into the space enclosed by the mold 2 above the lower compression member 3.
  • an oil mist is sprayed on to the inner walls of the mold from a number of nozzles 40 provided in the lower compression member 3.
  • FIG. 2 the mold 2 is raised to its upper extreme position and the contents of the charging container 16 have been completely dropped into the mold 2.
  • the walls of the charging container 16 enclose the upper compression member 4.
  • the pressing operation now begins, first with precompression of the charge produced by the rapid mo tion piston drives 8,9 of the upper compression member 4. At the same time the flaps of the openable wall 25 of the charging container 16 are opened, so that the container can be moved laterally out of the press. As soon as the charging container 16 gets back to the other end of its travel underneath the weighing container 21, at the left in FIGS. 1-4, the flap wall 25 closes and the guide conduit 24 is then lowered over the charging container, as shown in FIG. 3.
  • FIG. 3 shows the position of the press at the beginning of the main compression operation, during which the mold 2 is knocked downward against a counter force brought to bear by means of the piston drives 14 causing the mold to hover in an intermediate position.
  • the mold is driven downward only far enough to place the completely compressed block in about the middle of the mold 2.
  • the mold is held between opposing forces and upon the drive pressure exceeding a certain specific compression on the block being formed, it is dragged along downwards a little way.
  • the weighing container 21 When the pressing operation is terminated, the weighing container 21 at the same time becomes filled with a new dosage quantity of material for compression, at which point the conveyor chute 20 is momentarily held still in nondelivering position, as shown in FIG. 3.
  • the trap bottom (not visible in the drawing) of the weighing container 21 opens and allows the filling material to be dumped into the charging container 16.
  • the weighing container 21 is then closed again and the inflow of granular material from the conveyor belt 19 sets the conveyor chute 20 back into operation.
  • the upper compression member 4 begins to move towards its upper terminal position under its quick return drive, as shown in FIG. 4.
  • the mold 2 is lowered, which causes the block 37' that rests on the lower compression member 3 to be stripped from the descending mold 2.
  • the press is returned to its normal or idle position shown in FIG. 1 and the operation cycle can begin again.
  • the guide conduit sleeve 24 is necessary to avoid risk of loss of the input material, because during the stage shown in FIG. 2 the mold 2 is held hovering between opposing forces and can also be dragged along somewhat by the downward push of the close-fitting upper compression member 4. That downward movement of the mold which is not necessarily always of the same extent, is communicated to the bracket 15 and the charging container 16, but the presence of the guide conduit 24 lowered over the top of the charging container l6 prevents that downward movement from opening up a gap through which any of the material dumped from the weighing container 21 into the charging container 16 might escape.
  • a block molding press particularly suited for forming block electrodes by compression of granulated material mixed with a binder comprising, in combination with a press frame:
  • a laterally movable charging container (16) movable between a position below the discharge of said dosage device and a position above the upper opening of said mold means (2) and having an openable wall (25), said charging container means (16) also being'open above and below and being slidably supported on a surface flush with the top of said mold means (2) provided by bracket means (15) affixed to said mold means (2);

  • said actuating means and said lateral drive means being so synchronized that one of said compression means protrudes at least part way into said charging container (16) before said charging container is moved away from its said position above the upper opening of said mold means.
  • said dosage device (18) includes a weighing container (21) disposed above the loading position of said charging container l6) and in which there is provided between said weighing container and said charging container a vertically movable guide conduit (24) and in which vertical drive means (23) are provided to displace said guide conduit (24) so as to enclose a path between said weighing container (21) and said charging container (16) when the latter is in its loading position, regardless of any vertical lowering of the position of said charging container (16) as the result of displacement of said mold means (2) by a concurrent pressing operation.
  • a block molding press as defined in claim 1 in which said upper compression means is movable by said actuating means and in which said actuating means are arranged to insert said upper compression means partly into said charging container (16) when said charging container is in its position above the upper opening of said mold means, and in which, further, said operating means are arranged to open said wall (25) to permit said lateral drive means (17) to move said charging container (16) away from said position above the upper opening of said mold means.
