Definitions

  • the invention relates to a frame for a rotary tablet press according to the preamble of patent claim 1.
  • a rotary press usually contains a rotor with upper and lower punches, which cooperate with guide curves and printing stations.
  • the printing stations contain upper and lower rollers which, when passing the stamps, press them against each other against the material to be pressed in dies of a die plate.
  • the pressure rollers which are attached to an upper or lower crossbar of a press frame, can be adjusted in height.
  • the rotor is driven by a suitable drive motor, wherein DE 10 2004 040 163 has become known to arrange a drive motor immediately below the rotor on the shaft of the rotor or to integrate the drive motor in the rotor. In the latter case, it is an external rotor motor, and the stator sits on a pillar in the frame of the tablet press, which also supports the rotor.
  • the rotor of the tablet press is driven at high speed, which in turn make the press dies at high speed linear movements. As a result, not inconsiderable vibrations are generated, which, if not damped, are introduced into the underground. In addition, there is a significant noise.
  • the invention has for its object to provide a particularly simple design and the individual functions of the rotary press counter coming construction, with which the vibrations occurring during operation of the rotary press are attenuated or largely decoupled from the ground.
  • a first horizontal support member which supports the rotor with the drive motor and a lower pressure roller unit at least one printing station.
  • a second horizontal support member is arranged on which, inter alia, the upper pressure unit of the printing station is mounted.
  • the curve elements can be mounted, which are required to guide the upper punch.
  • First and second horizontal support members are secured together by at least two vertical supports, and the supports are supported by a pair of spaced damping members on the undercarriage.
  • two diametrically opposed supports are provided.
  • the support elements have according to a further embodiment of the invention, the outline of a polygon and are equal to each other in outline.
  • the support elements of suitable lattices with flat top and bottom sides are formed.
  • the support elements in turn make housing for receiving various aggregates, such as adjusting devices for pressure rollers, drive for the filling device, drives for guide curves, etc ..
  • the base frame on a base plate which is supported by feet on the ground.
  • a hood surrounding the frame can be supported on a damped base plate according to a further embodiment of the invention.
  • the hood serves to dampen the airborne sound.
  • a base plate 10 is supported by feet 12 on a substrate.
  • the feet 12 may include damping elements.
  • a subframe 18 or 20 On opposite sides of the base plate 10 is a subframe 18 or 20 with two pairs of spaced short column sections 22 and 24, respectively arranged, which are connected by a transverse web 26, wherein the pairs are diametrically opposite each other.
  • Columns 14, 16 are supported on the underframe 18 and 20, respectively via two damping elements 28.
  • the columns 14, 16 are approximately U-shaped in horizontal section, with the main supporting force being transmitted via the cross-sectionally trapezoidal leg sections, which are connected by a thinner web section.
  • a lower support member 30 and an upper support member 32 are arranged between the pillars 14, 16, a lower support member 30 and an upper support member 32 are arranged.
  • the support members 30, 32 represent a kind of latticework with flat upper and lower sides. They are octagonal in outline, with the columns 14, 16 extending over one side of the octagon and connected thereto in a suitable manner, for example by screwing. From the outline, the support members 30, 32 are the same.
  • the lower support member 30 is disposed at a certain distance above the base plate 10 and carries centrally a column 34 on which a rotor 36 is rotatably supported for a tablet press.
  • the rotor contains inter alia a die plate 38 with die holes 40, as known per se.
  • Upper and lower punches which are guided in the rotor above and below the die plate 38, have been omitted for the purpose of illustration.
  • the upper and lower punches cooperate with an upper pressure roller unit 42 and a lower pressure roller unit 44, respectively. They have at least one pressure roller 46 and 48, which are rotatably mounted in a suitable bearing member 50 and 52, which is fork-shaped.
  • the fork-shaped bearing components 50, 52 are of columnar guides 52, in particular to recognize the bearing member 52, guided vertically.
  • the columns 54 are held by suitable brackets, the lower of which is shown at 56.
  • the brackets 56 are attached to the lower support member 30 and the upper support member 32, respectively. In this way, the compressive force of the rollers 46, 48 can be axially introduced into the upper and lower punches, without causing excessive deformations.
  • An unrecognizable electric drive motor is integrated in the rotor 36. Its outer runner is rotatably connected to the rotor 36, while the stator is fixedly connected to the column 34. The storage of the rotor 36 on the column 34 is also not visible.
  • a cabinet 58 is housed for the tablet press shown.
  • Lower and upper support members 30, 32 and pillars 14, 16 form a stable frame which receives all forces and vibrations generated by the rotary tablet press shown.
  • the generated structure-borne noise of the frame is attenuated via the four damping elements 28, so that the base plate 20 is low in vibration and transmits relatively few vibrations into the ground.
  • a hood 60 is supported (dashed lines), which surrounds the entire frame.
  • the hood 60 dampens the airborne sound produced by the tablet press.
  • the column after Fig. 2 has two parallel spaced, in cross-section square supports 60, 62, which are interconnected at the top and bottom by transverse plates 64, 66. They are also connected by a diagonal tension strut 68.
  • the plates 64, 66 laterally with the platforms 32, 30 after Fig. 1 connected.
  • Foot plates 70 are with the damping elements 28 after Fig. 1 connected.
  • Openings 72, 74 in the plates 64, 66, comparable to the non-designated openings in Fig. 1 allow penetration into the interior of the platforms 30, 32.
