Definitions

  • the invention relates to a device in tableting machines for feeding molding compounds, especially those related to their flowability are problematic, in one Feed channel that ends in a filling shoe, a control or controllable metering device is arranged.
  • the filling shoe with the help of which the molding compounds the individual Press chambers are fed, is largely sealing for example a round tray table or a die table on. It covers a large number of bale chamber openings.
  • the filling shoe is mostly during tableting filled with molding compound from a feed channel a reservoir got there.
  • the molding compounds used for the tablet production exist from a mixture of active ingredients and carrier substances. Most of the powdered carrier substances have the task, to make the active ingredients manageable in the form of tablets. For this purpose, the carrier substances have to be under Exposure to pressure in a permanently stable shape let bring.
  • the molding compound generally passes from the storage container gravity feed into the filling shoe.
  • Vibrators are supported in some feeding systems and / or stirring devices used. With some feeding systems If several paddlewheels are used in the filling shoe, which are stored around vertical axes, immediately above turn the tablet table. They are among themselves in engagement.
  • the impeller wheels transport the molding compound out of the feed area and push it continuously through the bale chamber openings.
  • the excess, not the same Pressing compound taken up by the press chambers is in the filling shoe transported and mixed along the inner wall in a circle. In the gaps between the blade edges and the The molding compound becomes the tablet table and the filling shoe inner wall permanently compacted and tumbled.
  • the impeller is an endless belt guided by two wheels used.
  • the driven endless belt has on its outside a variety of cams that the molding compound of a feed hopper from to the die holes.
  • the Feed hopper is part of an adjustable orifice metering. For this purpose, it is rotatably mounted on the filling shoe about its longitudinal axis, its outlet opening being eccentric to its Axis of rotation arranged and only congruent in one position with the filling opening of the filling shoe.
  • a motor Twisting the feed funnel in relation to the filling shoe the molding compound flow is changed controllably.
  • the molding compound is also in the filling shoe through the endless belt permanently transported, mixed with his cams and walked.
  • the closing movement of the feed hopper also leads on its lower edge for baking the molding compound.
  • the the resulting cross-sectional change causes an uncontrollable Control behavior of the dosing device.
  • the invention is therefore based on the problem of a feed device to create molding compounds with which the molding compound during the tableting process without changing their bulk density and their flow behavior controlled or regulated the Filling shoe is fed and stored there temporarily. All parts the feed device should be designed such that it easy to assemble and easy to clean. Furthermore should the disadvantages known from the prior art avoided become.
  • An at least controllable metering device is located in the feed channel arranged, the one, surrounded by a housing, motor driven cell roller with at least four cells, the approximately horizontally oriented axis of rotation the cell roller is arranged transversely to the feed channel.
  • a motor-driven cellular wheel for loading one Briquette press is known from DE-PS 595 130.
  • This Document describes an eight-winged cellular wheel, in the coal dust for portioning the individual briquette masses through an adjustable slot from the side into the Cells is erased. The bulk material fills one completely open control slot the cell space completely out.
  • a cell roller is known from US Pat. No. 4,238,058 known with central inflow. With this cell roller the individual cells due to the special design of the Inlet completely filled, so that here too Bulk between the cell walls and the cell roller surrounding housing is maltreated.
  • the cell roller is in the Feed channel to the filling shoe of the tableting machine - at least in terms of construction - with an overshot water wheel comparable.
  • the molding compound trickles from above, for example coming over the feed channel onto the cell roller. In doing so the cells just moved under the channel opening filled one after the other. At the same time, the filled cells in the feed channel below the cell roller emptied. This lower part of the feed channel opens into the Filling shoe, whereby it can also be part of the same.
  • the cell roller is driven to the water wheel. Corresponding the speed that can be set on your drive promotes them a certain amount of molding compound per unit of time.
  • the cell roller is surrounded by a housing whose inner contour only Transport can be slightly larger than its outer contour the molding compound is reduced by lowering the drive speed or be stopped.
  • the imaginary center lines of the feed channel and the metering device oriented transversely to it be skewed to each other.
  • the molding compound despite the effect of gravity often not in sufficient quantity in the filling shoe slips, scooped from the upper feed channel into the lower one or poured.
  • the diameter of the cell roller is larger than twice Inner diameter of the upper part of the feed channel or at a rectangular feed channel larger than its double Width.
  • the length of the cells is preferably greater than that Sum of the inside diameter of the feed channel - or its Expansion parallel to the axis of rotation of the cell roller - and the quotient from the double cell depth through the tangent the angle of repose of the molding compound. Accordingly, it has the cell roller housing penetrating feed channel a smaller Cross section as the maximum parallel longitudinal cut area through the cell roller.
  • the molding compound can the individual Neither fill cells to their full length nor can they adhere to the Sprinkle the cell roller freely.
  • the cells are filled.
  • the cell volume is not a direct dosage size, since the degree of filling of the cells is a function of the physical Properties of the molding compound is.
  • the cell cross section and the cell length are dimensioned such that the Pressing compound for cells on the front of the cell roller are open, do not touch the end walls of the housing. Hence The molding compound does not get between parts that are relative move towards each other.
  • the cells are arranged parallel to the axis of rotation and have an almost semicircular cross-sectional contour. Such a shape enables a smooth, edge-free surface of the cell, which is both inexpensive manufacture as well as easy to clean.
  • Other cross-sectional contours such as. polygonal, triangular, trapezoidal etc. are also possible.
  • the bars act between the cells like scoops that are almost perpendicular to the there tangent or tangential plane of the inner wall of the Housing.
  • This cell and web design prevented compressing the molding compound in front of the respective web edge. Possibly can be the angle between the sliding web edge and the corresponding housing tangent also more than 90 ° be.
  • cells are also conceivable which not exactly straight, but e.g. crescent-shaped run curved. These cells, their curved Course mirror-symmetrical to the average cross-sectional area are aligned in terms of their sweeping so that the side edge area of the cells is the middle area - seen in the direction of rotation - advanced.
  • This shape prevents additionally a contact of the molding compound with the end walls of the housing.
  • Another possibility is the molding compound Keeping away the end walls is keeping the cells with to be provided on the side edges or laterally via cover disks to limit.
  • the cell depth corresponds to at least the maximum, half Width of the cells.
  • the cell width is the clear distance two adjacent bridges. Among other things about the cell depth the molding compound throughput per unit of time is determined constructively. To minimize the grinding and compacting of the Molding compounds between the inlet edges of the feed channel and Ridges of the cell roller prefer deep cells.
  • the feed channel penetrating the housing of the cell roller makes an angle of, for example, with the vertical 20 to 50 °.
  • the angle is generally dependent on the spatial conditions predefined within the tableting machine. In in some cases there is also a vertically aligned feed channel possible.
  • the imaginary center line of the feed channel intersects the Rotation axis of the cell roller, preferably in the area of half length.
  • the bulk quantity distribution is within of a cell mirror-symmetrical to the cross-sectional area in the center of the cell.
  • an inclined feed channel which also the housing the cell roller cuts vertically and in the center
  • the cell roller selected a direction of rotation in which the Cell trickling molding compound first by rotating the cell roller is raised. That is, the cell moves on it Circular path a little further up around its axis of rotation, before it reaches the highest point. This makes it down leading pivoting movement of the individual filled cells from the highest point less than 180 °. Consequently, the falls Molding compound before reaching the horizontal housing area in the lower part of the feed channel or directly in the filling shoe.
  • the molding compound is not with the help of Ridges or cell partitions are pushed through the housing.
  • the cell roller is powered by a DC motor with a tachometer generator driven.
  • the tachometer generator enables one Speed monitoring of the DC motor.
  • On the DC motor a gearbox is flanged with which the engine speed ins Slow is translated.
  • Between the transmission output shaft and the shaft of the cell roller is preferably a torsionally rigid, Movable or a torsionally flexible coupling arranged.
  • the drive of the cell roller can also be operated in a controlled manner.
  • a fill level sensor is accommodated at least in the fill shoe. It is preferably located in the front area of the Filler shoe that is furthest away from the molding compound feed lies. The relative movement jams in this area between the tablet table and the filling shoe Molding compound.
  • One arranged there in an upper filling shoe zone Sensor that works, for example, capacitively or inductively, recognizes the degree of filling. According to this degree of filling a regulation causes a speed change on the DC motor. This regulation is only indirectly dependent on the Press performance of the tableting machine.
  • the volume flow of the molding compound passing through the filling shoe Speed changes can be varied over a wide range.
  • the speeds are too high undesirable because such molding compounds on the warming Fix cell partitions.
  • the cross-sectional areas can achieve volume flow without increasing the speed the cells are enlarged along the axis of rotation, e.g. by increasing the cell depth.
  • the cell roller have a frustoconical basic shape. At this Shape can be maintained with the same thickness of the cell walls very large changes in cell cross section along the Realize the axis of rotation.
  • Another alternative is to between the cell walls the rigid cell partition walls made of flexible material to manufacture.
  • elastic foils can be attached there which are e.g. to Axis of rotation or an axis laterally offset to it to be pulled. This creates cells with a V-shaped cross-section, the depth of which depends on the respective preload is.
