Definitions

  • This invention is directed to a briquette machine that manufactures briquettes.
  • a briquette machine that comprises a pair of rolls that solidify raw material by compressing the raw material that is supplied from a hopper and forms briquettes is known (see, for example, Patent Documents 1 and 2).
  • Patent Document 1 JPH09-192896
  • Patent Document 2 JPH06-55299
  • this briquette machine has the following problem. That is, if the pockets that are formed on each outer surface of the rolls do not match, the briquettes that are manufactured by the machine are likely to have misalignment or burr, which lower the quality of the briquettes.
  • One method that enables the pockets on one roll to match those of the other roll is by resetting the positions of the rolls. But usually the rolls are disposed within a frame that surrounds them. So, resetting the positions of the rolls would require work that would lowers the efficiency of resetting the positions of the rolls.
  • the present invention is to provide a briquette machine that can maintain the quality of the briquettes while it can increase the efficiency of the work to match the pockets of one roll with those of the other roll.
  • the briquette machine of the present invention comprises a first roll and a second roll that each are ring-shaped, having the axis of rotation of the first roll and that of the second roll being disposed parallel to each other and each roll having pockets on its outer surface whereby raw material is compressed between the pockets of the first roll and those of the second roll, a driving unit that produces a driving force for rotation, a first coupling member that conveys the driving force for rotation of the driving unit to the first roll, a rotating member on the roll-side that rotates with the second roll as one body, a rotating member on the side of the driving unit that is rotated by the driving unit, a mechanism for adjusting the position of the rotating member on the roll-side along the direction of the rotation of the rotating member on the roll-side relative to the rotating member on the side of the driving unit, and a second coupling member that conveys the driving force for rotation of the driving unit to the second roll (hereafter, the first invention).
  • the briquette machine having the structure of the first invention is able to have the pockets of the first roll match those of the second roll by adjusting the position of the rotating member on the roll-side along the direction of the rotation of the rotating member on the roll-side relative to the rotating member on the side of the driving unit.
  • the adjustment of the position is carried out by the mechanism for adjusting the position that is disposed on the second coupling member.
  • the briquette machine of the present invention can compress the raw material by the coordinated work of the pockets of the first roll and the pockets of the second roll, of which both pockets are matched. So, the quality of the briquettes is maintained.
  • first coupling member and the second coupling member are exposed above a frame. So, by installing a mechanism for adjusting the position on the second coupling member, the efficiency in matching the pockets can be improved.
  • the briquette machine according to the first invention is modified to be one wherein the mechanism for adjusting the position is disposed at the position that is to the outer side in the radial direction as seen from the center of the rotating member on the side of the driving unit.
  • the mechanism for adjusting the position comprises a nut disposed so that the axis of the nut is laid parallel to the tangential direction or the radial direction of the rotating member on the side of the driving unit, a bolt that is screwed into the nut, and a pressed portion that is formed on the rotating member on the roll-side where the tip of the bolt contacts the rotating member on the roll-side wherein the pressing force is exerted by the tip of the bolt in the tangential direction or the radial direction of the rotating member on the roll-side as the bolt is screwed into the nut (hereafter, the second invention).
  • the work that enables both pockets to match can be performed by the following process. Namely, first, the numerical correlation between the rotation of the bolt and that of the rotating member on the roll-side relative to the rotating member on the side of the driving unit is to be obtained. Next, the necessary degree of rotation of the bolt is calculated based on the data on the amount of the misalignment of the pockets that is obtained from the briquettes formed by the first roll and by the second roll and the correlation obtained as described above. If the bolt is screwed into the nuts by rotating the bolt by the degree of rotation thus calculated, the pressed portion is pressed by the end of the bolt in the tangential direction of the rotating member on the roll-side.
  • the rotating member on the roll-side is rotated relative to the rotating member on the side of the driving unit so that the pockets on both sides match.
  • the efficiency of the work for matching both pockets is improved compared with one where matching the pockets is carried out by examining the briquettes that are formed by compressing the raw material. This is because the work for matching the pockets of the present invention does not require examining the briquettes.
  • the briquette machine according to the second invention is modified to be one wherein the mechanism for adjusting the position is disposed to the inside in the radial direction of the outer surface of the rotating member on the roll-side and the inside in the radial direction of the outer surface of the rotating member on the side of the driving unit (hereafter, the third invention).

  • the briquette machine 10 is able to have the pockets 28 and 30 match by having the position in the rotational direction of the rotating member on the roll side 64 adjusted relative to the rotating member on the side of the driving unit 66, by means of the mechanism for adjusting the position 86 provided on the second coupling member 20.
  • the briquette machine 10 can form the briquettes by compressing the raw material with the pockets 28 and 30 that were matched, such that the quality of the briquettes can be maintained.
  • first coupling member 18 and the second coupling member 20 are exposed beyond the frame 27. So, by installing the mechanism for adjusting the position 86 at the second coupling member 20, the efficiency of matching the pockets 28 and 30 is improved.
  • the following procedures can be applied so as to enable the pockets 28 and 30 to be matched. That is, first the numerical correlation between (1) the rotation of the bolt 90 and (2) the rotation of the rotating member on the roll side 64 relative to the rotating member on the side of the driving unit 66 is to be obtained. Next, from the amount of the misalignment between the pockets 28 and 30, as obtained from the briquettes manufactured by the first roll 12 and the second roll 14, and the numerical correlation thus obtained, the degree of the rotation of the bolt 90 that is required is calculated.
  • the pressing force F at the end of the bolt 90 is exerted on the pressed part 92 in the tangential direction of the rotating member on the roll side 64 whereby the rotating member on the roll side 64 is rotated relative to the rotating member on the side of the driving unit 66 so that the pockets 28 and 30 are led to match.
  • the pockets 28 and 30 matched without actually deciding if the pockets 28 and 30 are matched. So, the efficiency of the work to match the pockets 28 and 30 is improved.
  • the mechanism for adjusting the position 86 is located at a position that is to the inner sides of the outer surface 64 A and 66A of the rotating member on the roll side 64 and the rotating member on the side of the driving unit 66, respectively. So, the mechanism for adjusting the position 86 is prevented from contacting any object that is placed outside the rotating member on the roll side 64 and the rotating member on the side of the driving unit 66, while they are rotating.
  • the pressure detector 124 that is used as a detector can detect the pressure more accurately than can a detector that uses an electric current. So, it can more easily be controlled.
  • the rotation of the feeder screw 24 is controlled so that it increases or decreases depending on the increase or decrease of the pressure between the other end of the cylinder rod 110 and the bearing unit on the movable side 46.
  • a briquette machine of the following structure can also be used.
  • the first roll 12 can contact, and retract from, the second roll 14 in the radial direction. Further, if the force is generated in such a way that the second roll 14 retracts from the first roll, then the first roll 12 is pressurized to move by the hydraulic cylinder 128.
  • a pressure detector 130 At the bottom end of the hopper 22 is provided a pressure detector 130 that detects the pressure when the raw material is pushed down and between the first roll 12 and the second roll 14 by means of the feeder screw 24.
  • the variable-speed control motor 26 is controlled by the control unit 126 so that the rotation of the feeder screw 24 decreases or increases corresponding to the increase or decrease of the value that is detected by the pressure detector 130.
  • a current detector 132 that detects the current of the driving motor 32 or the electric power detector 133 that detects the power consumption of the driving motor 32 can be used as a detector that is connected to both the control unit 126 and the driving motor 32 and that is positioned between them.
  • the variable-speed control motor 26 can be controlled by the control unit 126 so that the rotation of the feeder screw 24 decreases or increases corresponding to the increase or decrease of the value that is detected by the current detector 132 or the electric power detector 133.
  • the current detector 132 If the current detector 132 is used as a detector, it will reduce the cost, compared with the cost when a pressure detector is used. If the electric power detector 133 is used, it will reduce the cost, compared with the cost when a pressure detector is used.
  • the electric power detector 133 which is not affected by the voltage, can achieve a more accurate control than can the current detector 132.
  • the nut 88 is disposed in such a way that it has its axis running in the tangential direction of the rotating member on the side of the driving unit 66.
  • the pressed part 92 extends in the radial direction of the rotating member on the roll side 64.
  • the nut 88 can be positioned in such a way that it has its axis running in the radial direction of the rotating member on the side of the driving unit 66.
  • the pressed part 92 can be positioned in such a way that it slants against the radial direction and the tangential direction of the rotating member on the roll side 64.
  • the mechanism for adjusting the position is constituted in this way, by rotating the bolt 90 by the degree of rotation that was previously calculated and by having it screwed into the nut 88, the component force F of the pressing force at the end of the bolt 90 that is generated against the pressed part 92 is obtained, where the component force F is generated in the tangential direction of the rotating member on the roll side 64,.
  • the component force F can rotate the rotating member on the roll side 64 relative to the rotating member on the side of the driving unit 66, whereby the pockets 28 and 30 can be matched.
  • the second roll 14 which is on the side of the bearing unit on the fixed side 56, is used.
  • the mechanism for adjusting the position 86 that is disposed on the first coupling member that is connected to the first roll 12 that is on the bearing unit on the movable side 46 can also be used.
