Definitions
- the present invention relates to a compacting unit for a powder compacting machine.
- a compacting unit for a powder compacting machine.
- Such compactor is known from DE 891 642 C. There the torque transmitted via a separate wedge or several. The transfer high torques are not possible.
- Another one Compacting unit is known from US-PS-3,234,769. There must go to Replacement of the compaction roller dismantled the bearing become.
- Such compacting is also known from the prospectus "powtec compacting / granulating machine RC 100 x 30 for laboratory and Production.”
- the compacting unit easy to access and disassemble. This is in some compacting plants by a so-called flying bearing of the drive shafts reached. With these Compacting units, the compaction elements are accessible from the front, without having to dismantle the drive shafts.
- the invention solves this problem with the features of Main claim.
- the advantage of the invention is that at less Remaining quantity and thus little waste after processing the set-up time for cleaning the compacting unit in one batch is low.
- the rollers are easily interchangeable, Rolls of different surface properties can be removed and installed quickly and easily.
- This advantage is due to the successful integration of the Principle of compacting units with two-sided drive shaft in a design with easy access to the Roller attachment without dismantling the upstream bearing achieved.
- the drive shaft is supported on two sides.
- the area of rotation lies between the bearing points of the compression elements.
- the powder material is in the compression gusset promoted and through the convergent geometry in the Nip is forced in, where the compaction takes place.
- Tripartite drive shaft This creates two stub waves, each intercepted in a deposit while the shaft center piece is fixed to the compaction roller connected is.
- the bearing stub and the shaft center piece have mutually assigned rotary drivers, the turning drivers are e.g. in the transverse direction or in the longitudinal direction to the longitudinal axis of the drive shaft in or out of engagement brought.
- roller center piece can be put together with the compacting roller in at least one Rotational position transverse to the longitudinal direction from the drive shaft remove.
- the entire housing space, which contains the compression elements surrounds, is thus easily accessible and can therefore be cleaned with little effort.
- the axial clamping device brings about a positive fit Engagement of the mutually associated rotary driver, the also under operating loads, especially due to transverse loads, Relative movements between the shaft ends and excludes the shaft centerpiece in the micrometer range.
- cylindrical roller bearings offers more the advantage of large ratios of outside diameters to inner diameters.
- the load-bearing cross-sections can be make the drive shaft large enough so that also Hollow shafts are possible.
- Hollow shafts also offer the advantage that the axial clamping device realized by a clamping screw that can be separated from the one wave stub by the Shaft center piece extends into the other shaft stub and screwed in there while engaging the bottom its screw head on the first shaft stub.
- the clamping screw can be used with a push-off device be equipped, which facilitates the disassembly. Because using cylindrical roller bearings the drive shaft build hollow cylindrical with large diameter can, it is sufficient for the transmission of the occurring torques to design the rotary drivers as tongue and groove combinations. Every tongue and groove combination runs secantial or diametrically to the drive shaft. Trials have shown that a single tongue and groove combination for each pair of Drivers can be sufficient. Other embodiments are not excluded.
- a machine frame 2 there is a vertical one Filler neck 3 housed, the filler opening is accessible from the outside.
- the filler neck 3 opens into a vertical one Feed hopper 4. Comes in the convergent hopper area Agitator 5 um.
- a screw conveyor is coaxial with the agitator 5 6 coupled.
- the drive of the agitator and screw conveyor takes place via an angular gear 7 at the upper end of the feed hopper 4. This is done by a worm motor 8, which is coupled to the input side of the bevel gear 7 is.
- the compacting unit 9 essentially has two compression elements 10, 11 on. This is in present case around two compaction rollers facing each other are arranged in parallel, the distance between the roller axes slightly larger than the sum of the two roll radii is.
- the rotary movement of the compacting rollers is such that their Surfaces in the compacting gusset in the same direction and have the same high speeds.
- the compacting unit 9 receives its Rotary movement impressed by the compactor motor 14, the either via a transfer case with one of each two drive shafts of the compression elements 10, 11 connected or only with one of the drive shafts. In this Fall drives the first drive shaft via a pair of spur gears the second drive shaft and in this way the second compression element on.
- a downstream can be located at the output 15 of the compacting unit Processing, e.g. through a pelletizer 16th
- Fig. 1 shows further details.
- the compacting unit is symmetrical Has structure and consists of two compaction rollers.
- the drive shaft 17 of the first compacting roller 10 is rotatably connected to the compactor motor 14.
- the Power flows from Kompaktierwerkmotor 14 via the drive shaft 17 on the gear 19 arranged at the end. This is in constant engagement with another Spur gear 19a, which with the drive shaft 18 of the second Compaction roller 11 is coupled.
- each spur gear 19, 19a has a Key 20, 20a coupled to the corresponding drive shaft.
- the pitch circle radii of the spur gears 20, 20a are the same large, therefore the rotational speeds correspond of the two compaction rollers are identical.
- the drive shaft 17 - and likewise the drive shaft 18 - in the longitudinal area in front and behind the compacting roller 10 and 11 each have a stub shaft 23 or 24 forms, of which at least the one below the torque 50 of the drive shaft 17 is on his inner end 25 or 26 a rotary driver 27 or 28 wearing.
- each drive shaft 17 or 18 first division level 21 or 22.
- the shaft is on this Way in the longitudinal area between the two division levels 21, 22 each interrupted radially. From the continuous drive shaft is a bit removed, so to speak. This removed piece is now the subject of a shaft center piece 29, which is connected to the compacting roller 10 or 11 is.
- the shaft center piece contributes to the rotary drivers 27 or 28 complementary rotary drivers.
- the rotary drivers are in positive engagement with each other.
- the rotary drivers are with respect to the transverse direction Drive shaft 17 or 18 uninhibited. This way the compacting roller crossways with the shaft center piece pull out between the shaft ends 23,24 as long as the corresponding rotary position of the compactor this Permitted with regard to the compact housing open at the top.
- an axial tensioning device 30 provided which the two shaft ends with the shaft center piece then rigidly couples with each other when the shaft center piece in the inserted position between the wave ends.
- Fig.1 shows that of the shaft ends 23.24 each in the housing of the compacting 9 in a roller bearing 31,32,33,34 is rotatably supported.
- both shaft ends together with the shaft center piece 29 be provided with an aligned bore 36.
- a clamping screw 37 at its screw tip has a thread 38.
- This thread 38 corresponds with a hollow thread 39 in the first shaft stub 23.
- the clamping screw 37 in turn is supported with the Underside of their screw head 14 on the end face of the second shaft end 24. If the clamping screw 37 is tightened, this creates an axial tensioning force, which the first shaft end 23 and the second Stub shaft 24 in the direction of the compacting roller 10 forces. In this way, the compacting roller 10 between the first stub 23 and the second stub 24 pinched.
- the diameter of the screw shaft 41 with a transition fit (e.g. H7, h7 or H7, f8) fitted in the bore 36.
- the area of the transitional fit extends from the first shaft end 23 via the shaft center piece into the second shaft end 24.
- Tensioning screw 37 therefore arises in the highly stressed area between the bearing points of the drive shaft in the transverse direction construction subject to bending stress only, which is free of play in the transverse direction.
- the larger diameter of the screw shaft on the other hand is freely movable in the axial direction. There the screw is only in direct contact with the Wall of the bore 36 to the transverse loads that occur record without play. The length of the screw shaft is therefore less than the length of the aligned Holes in the first shaft stub, shaft center piece and second wave stub to the point where the first Shaft stub 23 the screw thread for the screw tip having.
- the clamping screw 37 on her Screw head 40 provided with a support ring 42, with which the clamping screw 37 on the free end face of the second shaft end 24 rests and in this way the axial clamping force is coupled into the hollow shaft combination.
- Fig. 5 shows further details of the clamping screw 37th
- the screw shaft tapers in the area of the Screw tip to a smaller diameter thread 38, which is offset from the screw shaft 41 via an expansion zone 43 is.
- the large screw shaft is conical trained lead-in zone and then goes in a finely machined longitudinal area 44. In this finishing zone is between the screw shaft 41 and the Hole 36 made a transition fit. This zone practical extends to the storage area of the outside Wave stub 24 into it to the required tight To achieve a seat between screw shaft 41 and bore 36.
- the screw shaft can be slightly Continue the diameter server down to the screw head 40.
- the screw head 40 offers a key engagement surface on the one hand and on the other hand a support ring 42 which in the Installed condition on the free end face of the second shaft end 24 sits on.
- the support ring is continuous in the longitudinal direction Provide threaded holes in the assembled state of the Clamping screw blind in front of the end face of the second shaft end 24 mouth.
- a forcing screw can be screwed in here for disassembly, which with the screw thread 38 then removed Pushing the tensioning screw 37 axially out of its installation position.
- FIG. 2 shows, for example, a shaft stub 24 which is not coupled to the motor 14 of the compacting unit.
- a cutout 46 is provided at the front end, which serves to accommodate a feather key 20, 20a. On this way is between the shaft end 24 and the concerned Spur gear 19, 19a established a non-rotatable connection, while at the same time the spur gear in the axial direction can be pushed onto the shaft end 24.
- the end face is the radial division plane the drive shaft, from which the rotary driver protrude claw-like to complement with trained Interacting rotary drivers on the shaft center piece.
- the shaft center piece 29 has two correspondingly diametrically mounted recesses 47 whose Contour to the rotary drivers 27,28 is complementary.
- the rotational positions between the shaft ends and shaft center piece match identically, can with the clamping screw 37 removed, the shaft center piece Pull out transversely to the longitudinal direction of the drive shaft.
- the compacting roller 10 which is here is integrally connected to the shaft center piece 29, from the compacting housing removed.
- FIGS. 8 and 9 show further special features.
- Figure 8 shows another embodiment of the rotary driver 27 and 28 respectively.
- the rotary drivers are formed here by axial bores 48a, b, c, each in the shaft center piece 29 and in the shaft ends 23,24 are introduced.
- the axial bores can be placed in a common aligned position become.
- the complementary rotary drivers are replaced by a Insert pin 49 formed, the axial bores 48a, b, c appropriately enforced.
- the insertion pin 49 has on his Inserting end via an external thread, which with an associated Internal thread in the first shaft end 23 corresponds.
- Fig. 8 shows as a further special feature that the spur gear 19 on that Side of the compactor is on which also the torque 50 is initiated by the Kompaktierwerkmotor 14.
- This measure has the advantage that in principle only a pairing on one end face of the shaft center piece 29 must be provided from rotary drivers.
- Fig. 9 additionally shows that for this case the Pairing of rotary drivers and complementary rotary drivers also lie only on that side of the shaft center piece 29 must where the actually necessary for compacting Torques must be initiated.
- the shaft center pieces 29 have smooth faces.
- Fig. 9 also shows the special feature, that the torque transmission from drive shaft 17 the spur gear 19 via a double screwed driving ring 52 can take place, the two concentric to each other Bolt circles.
- the inside bolt circle 53 lies within the face by the drive shaft 17 is provided.
- the outer bolt circle 54 lies within the end face provided by the spur gear 19 becomes.
- Corresponding screw holes are behind the bolt circles arranged in alignment in the drive shaft 17 or the spur gear 19, so that a pair of circular arranged Driver screws results, which is a torque safe Transfer of the initiated torque 50 to the other Drive shaft 18 results.
- the clamping screw is also complementary 37 arranged within a centering sleeve 51. On this way the lateral forces and bending moments that are about the compacting unit can be transferred to the shaft combination, from the relatively easy to manufacture centering sleeve 51 added while the clamping screw 37 from an inexpensive Standard part can exist.
