Definitions

  • the present invention relates to a can filling device with a head part, which in operation is arranged above a rotatable can, and has a turntable that can be driven to rotate, the turntable using two calender rolls mounted on it over at least substantially horizontal axes, a fiber sliver in continuous deposits cycloid-shaped loops in the can, at least one of the calender rollers being drivable by a friction wheel running on a fixed annular surface of the head part and rotatably mounted on the turntable.
  • a can filling device of this type is known from EP-OS 175 072, but is complex and complex in construction.
  • a simplified can filling device of the type mentioned is also known from DE-OS 33 18 944.
  • the construction of this further known device is less expensive, but, due to the chosen construction, leads to an undesirable load on the sliver, so that breakages can occur, especially when the machine has been in use for a long time, and wear to undesirable play led the individual elements.
  • the axis carrying the friction wheel is pivotally supported at its end opposite the friction wheel, a helical compression spring arranged below the axis trying to pivot the axis upward and thereby the friction wheel engaging with the horizontal Holds the ring surface of the head part on which it rolls during operation. Wear of the friction wheel or tolerances in the construction are compensated by this spring.
  • the friction wheel and the one calender roll form a hollow unit which is rotatably mounted on the pivotable axis. This unit also contains a gear that meshes with another gear driving the second calender roll. As a result, the axis of rotation of the second calender roll is fixed on the turntable.
  • the design of the friction wheel with a horizontally extending surface is unfavorable because the friction wheel itself is deformed by this design, since the peripheral speed of the radially inner edge of the friction wheel must be lower than the peripheral speed of the radially outer edge of the friction wheel, the expression “ radial "here in relation to the axis of rotation of the turntable.
  • the constant deformation of the friction wheel due to this design necessarily leads to premature wear of the friction wheel, which increases the aforementioned difficulties in the area of the calender rolls.
  • the object of the present invention is to develop a can filling device of the type mentioned in such a way that with a simple and uncomplicated construction, a constant load on the sliver in the clamping area between the calender rolls can be achieved, so that the risk of Band breaks are significantly reduced, and the wear that occurs should also be kept low in long-term operation.
  • a first embodiment proceeds in such a way that the imaginary axis about which the friction wheel rotates is fixed in space, and the friction wheel has a conical surface that rolls on a complementary, conical ring surface of a window ring that the friction wheel in The direction of the imaginary axis for engagement with the window ring is adjustable or prestressable, and drives the calender roller assigned to the friction wheel directly or via a shaft representing the axis of rotation of the calender roller, possibly via a cone wheel arranged between it and the shaft or it and the calender roller .
  • the axis of rotation of the friction wheel can be attached to the turntable by means of conventional bearing arrangements such that the imaginary axis of rotation of the friction wheel is fixed in relation to the turntable.
  • a secure engagement between the friction wheel and the ring surface of the head part is achieved by axially prestressing the friction wheel having a conical surface. Furthermore, this cone-shaped surface can be designed so that no slippage and no deformation of the. By selecting the cone angle with regard to the dimensions of the individual elements and the selected working speed Friction wheels are created, so that no significant wear of the friction wheel can occur over a long period of time, which likewise leads to constant conditions in the clamping area of the calender rolls.
  • the friction wheel has, in addition to the conical surface, a cylindrical surface which is in contact with the surface of the calender roll and drives it directly.
  • This arrangement has a minimum of individual elements, it is very compact and enables the calender roller bearing to be made very rigid, so that the working conditions in the clamping area of the calender rollers always remain constant.
  • the conical surface of the friction wheel can be in contact with a conical wheel arranged on an end face of the calender roll.
  • the friction wheel with its conical surface can be in drive engagement with a cone wheel diametrically opposite the calender roll and drive it via the shaft mentioned.
  • the largest radius of the conical surface of the friction wheel should be arranged further away from the axis of rotation of the turntable than the smallest radius of this surface, ie that when a window ring is arranged above the turntable or the friction wheel the conical surface of the window ring on which the friction wheel rolls diverges upwards.
  • this should be arranged such that its conical surface complementary to the friction wheel converges in the direction opposite to the conical surface of the friction wheel.
  • An alternative solution to the problem according to the invention is characterized in that the imaginary axis about which the friction wheel rotates is arranged fixed in space and that the fixed ring surface is formed on a window ring which is prestressed in the direction of the axis of rotation of the spring plate and towards the friction wheel.
  • the prestressing of the window ring towards the friction wheel can be achieved by means of spring elements, for example by means of helical compression springs which press against the surface of the window ring facing away from the friction wheel and are supported on the head part. This prestresses the window ring in the manner of the pressure plate of a clutch, and if desired, the window ring can be brought out of engagement with the friction wheel by the attachment of some levers or actuating devices, so that the drive can be decoupled.
  • the cone wheel when driving the first-mentioned calender roll through the friction wheel via a cone wheel, the cone wheel can be in driving engagement with another cone wheel fastened on the axis of rotation of the second calender roll and thus also ensure the drive of the second calender roll.
  • the first-mentioned calender roll rotates about an axis arranged radially with respect to the rotary plate and itself has a conical surface, the tip of this conical surface on or in the is very close to the axis of rotation of the turntable.
  • the second calender roll then has the same shape as the first-mentioned calender roll, but is directed in the opposite direction to this.
  • This embodiment favors the distortion-free storage of the sliver.
  • the rotary drive of the rotary plate can be carried out by a motor which also brings about the rotary movement of the can, preferably via a drive belt encompassing an annular wall of the rotary plate.
  • FIG. 1 shows at 10 a pot-like turntable, which is rotatably mounted in the head part 12 of a can filling device by means of a bearing 14.
  • the turntable 10 is driven in operation by a belt 16 for a rotary movement about its axis of rotation 18.
  • the belt 16 itself is set in motion by a motor (not shown) via a shaft 19 and a pulley 20.
  • the drive belt 16 extends around the drive wheel 20 and around the upper flange of the pot-like turntable 10.
  • a window ring 22 which in this example is fixedly attached to the head part 12.
  • the pair of calender rolls serves to deposit the card sliver 24 coming from a guide in a known manner in continuous cycloidal loops in a can 26 arranged below the head part 12 and driven to rotate.
  • the rotary movement of the can is also accomplished by the shaft 18, the lower end of which via gear wheels, not shown a plate supporting the can 26 rotates.
  • the calender roll 22 is mounted in a rotationally fixed manner on an axis 28 which is rotatably mounted in two bearings 30, 32 of the rotary plate which are spaced apart from one another.
  • a cone wheel 34 At the end of the axis 28 opposite the calender roller 22 there is a cone wheel 34.
  • a friction wheel 36 which has a conical surface and is mounted on an axis of rotation 38 in a rotationally fixed but axially adjustable manner.
  • the axis 38 is rotatably mounted in a bearing in the side wall of the pot-like turntable 10.
  • the conical surface of the friction wheel meshes on the one hand with the corresponding conical ring surface 40 of the window ring, on the other hand with the complementary conical surface of the conical wheel 34.
  • the rotary movement of the turntable leads to a rolling movement of the friction wheel 36 on the conical surface 40 of the window ring and therefore also to a rotary movement of the cone wheel 34, which drives the calender roller 22 via the axis 28.
  • the rotary movement of the calender roll 22 is selected so that the card sliver 24 is pulled down and then placed in the can in the manner mentioned.
  • the second calender roll 23 shown in FIG. 2 lies parallel to the calender roll 22 and forms a nip with it.
  • the second calender roll is then driven by friction at the same rotational speed as the calender roll 22.
  • the second calender roll can also be driven, for example, either by meshing gears as shown in DE-OS 33 18 044, or with an arrangement as indicated in Fig. 3.
  • the cone wheel 34 meshes with a further cone wheel 42, which has the same shape as the cone wheel 34, but is directed in the opposite direction.
  • the arrangement is such that the second cone wheel 42 with the friction wheel 36 is not engaged, but only with the cone wheel 34, so that it rotates in the other direction of rotation as the cone wheel 34, but at the same speed.
  • the second cone wheel 42 is connected to the further calender roll via a further axis corresponding to the axis 28, this further axis also being rotatably supported on the turntable in positions spaced apart from one another.
  • the arrangement of the cone wheel 42 of the further axis and the further calender roller is the same as the arrangement of the cone wheel 34, the axis 28 and the calender roller 22, except that the cone wheel 42 is directed in the opposite direction to that Cone wheel 34.
  • Fig. 4 shows a section through the friction wheel 36, it being seen that the friction wheel is mounted on a rigid rotatable axis 38 in a rotationally fixed manner by means of a tongue and groove arrangement.
  • the friction wheel 36 is axially displaceable on the axis 38 and is pretensioned in the axial direction to the right in FIG. 4 by means of a helical compression spring 60 which is attached to the left end face of the friction wheel 36 on the one hand and to the left end of the axis 38 on the other hand , disk-like abutment is supported.
  • the friction wheel is constantly pressed to the right by the spring 60, so that the desired contact pressure with the conical surface of the window ring 20 is created.
  • the spring compensates for any wear on the friction wheel or on the window ring, in that it always generates the desired contact pressure between the friction wheel and the window ring.
  • the compression spring 60 ensures that there is sufficient contact pressure with the cone wheel 34.
  • the friction wheel can also be made adjustable, for example by using spacers 64 packs between the friction wheel 36 and the abutment 62 in order to achieve the desired setting relative to the window ring 20. This arrangement can be adjusted if wear occurs, by using more or thicker spacers.
  • the friction wheel 36 has, in addition to the conical surface, also a cylindrical surface 44 which is in direct contact with the circumference of the calender roller 22.
  • the second calender roll 23 is driven by the first calender roll 22 and is freely rotatable by means of an axis 48.
  • the geometric arrangement of the two calender rolls, as in all other exemplary embodiments, can be as described in the earlier Swiss patent application CH 01321 / 88-9 or in the earlier EP application with publication no. 338 277.
  • FIG. 8 A further embodiment variant can be seen in FIG. 8, the same components being identified with the same reference numerals here as in previous examples.
  • the cone wheel 34 is attached directly to the end face of the calender roll 22 or is made from it in one piece.
  • the adjustability of the friction wheel 36 is made here in accordance with the embodiment of FIG. 4 or 5.
  • FIG. 10 shows a further embodiment, which is designed somewhat differently than the previously described embodiments, but in which the same components are identified with the same reference numerals as before.
  • the smaller calender roll 23 mounted on an axis of rotation 48 which is mounted in fixed bearings 50 and 52 of the turntable. That is, the imaginary axis of rotation 54 of the calender roll 23 is arranged fixed in space in this arrangement with respect to the turntable.
  • the axis of rotation 48 of the calender roller 23 is extended outwards in the radial direction and carries the friction wheel 36 outside the turntable 10.
  • the friction wheel is designed here as a cylindrical wheel, although it could also be designed as a bevel gear.
  • the cylindrical wheel 36 runs on an annular surface 40 of the window ring 20, the window ring 20 being prestressed upward in FIG. 10 by means of helical compression spring 56, 58, so that there is always sufficient engagement between the friction wheel 36 and the window ring 20.
  • helical compression spring 56, 58 are shown in this drawing, it is understood that several such pairs of springs are arranged at regular angular intervals around the axis of rotation 18 of the turntable.
  • the friction wheel 36 has a diameter D2 which is somewhat smaller than the diameter D1 of the calender roller 23.
  • the diameter ratio of D1 / D2 is chosen such that no relative speed occurs at point P.
  • the calender roll 23 is the smaller one and drives the large calender roll 22.
  • FIG. 9 shows a shape for the calender rolls 22 and the calender roll 23 meshing with them, which is particularly favorable.
  • the outer surface of the calender roll 22 is namely a cone surface, the associated cone being arranged such that its tip lies on the axis of rotation 18 of the turntable.
  • the calender roll 23 has the same shape, but is directed in the opposite direction.
  • the axis 28 is slightly inclined with respect to the axis 18, so that the surface of the laying roller 22 runs horizontally in its deepest point, ie where it places the card sliver into the can.
  • the axis of rotation 28 of the calender roll 22 is directed radially with respect to the turntable 10.
  • the friction wheel can consist of a metal wheel with a rubber layer on the surface, it being possible to use all other soft-elastic, rubber-like substances instead of rubber, for example polyurethane.
  • 11 and 12 show two practical preferred arrangements which can be used with all previous embodiments. It can be seen that the card sliver is first passed through two deflection rollers 6, 8, which are arranged so that the nip formed between them lies on the axis of rotation of the turntable.
  • the turntable 10 is provided with a cover 60 which also rotates, the card sliver running through an inlet funnel 62 which is arranged on the cover and lies directly above the calender rolls 22, 23.
  • the calender roll 23 can also be referred to as a laying roll, since it ensures that the card sliver is deposited directly onto the card sliver that is already in the can.
  • the laying roller 22 has a diameter D which is selected such that the circumference of the laying roller 22 for a given position of the shaft 28 receiving the laying roller 22 extends a predetermined amount C deeper against the sliver can than the underside 64 of the turntable 10. Due to the fact that the circumference of the laying roller 22 protrudes deeper into the can 26, the laying roller 22 places the sliver directly on the sliver loops already in the can (also called sliver loops or sliver layers).
  • the amount C can be selected, for example, in the range from 1 to 10 mm.
  • the measure of the amount C depends, however, on the desired measure of the pressing of the strip to be deposited onto the strip layers already in the can 26 and is chosen at will.
  • the laying plate 66 which leads the calender roller 22 in the direction of rotation, has the known task of compressing the sliver deposited in the can 26 in combination with the spring-loaded spring plate, which presses the layers from bottom to top.
  • the spring for loading the spring plate is not shown, but lies in a manner known per se on the bottom (not shown) of the can 26.
  • peripheral speed of the laying roller 22 is selected such that there is no relative speed between the band 24 to be laid and the sliver already in the can.
  • the can 26 rotates in the direction B (FIG. 11) and the turntable 10 in the direction A.
  • the type of loop formation in the sliver can mentioned, with the rotating can 6 and the rotating depositing plate 66, is cycloidal.
  • a stripper 68 is provided.
  • This wiper 68 actually forms the previously mentioned storage plate.
  • Another stripper can be provided for stripping fibers from the calender roll 23.
  • This further scraper can be arranged as shown in EP 338 277.
  • Fig. 12 shows that the two calender rolls 22, 23 can be carried out with substantially the same diameter, but still retain the feature that the Storage roller 22 protrudes by the amount C below the turntable.
  • the peripheral surface of the laying roller does not have to be flat (cylindrical), instead it can e.g. be a hollow surface or have grooves that run essentially axially.
  • the two calender rolls can be encompassed by circulating belts which serve to guide the card sliver.
  • the circulating belts can be designed exactly as in Fig. 11 of the European application with publication no. 338 277.
  • further details from this European application can also be used with the arrangement according to the present application, if necessary.
