Definitions

  • the invention relates to a can with a rotating on a circular path, on a turntable or rotating ring located band outlet channel for a sliver, which outlet channel for the belt conveyor serving calender rollers are arranged upstream, and with a stationary sliver separating device which transversely into the orbit of the outlet channel Band stretching direction in a transverse groove of the turntable pivotally retracting and extending separating element.
  • a can of this type is known from DE-OS 28 21 325.
  • the Trennelenemt is designed there as a comb. In the area of the so-called funnel wheel, the latter moves into the fiber sliver channel, controlled by a rotating magnet, and which has a horizontally oriented slot for this purpose.
  • the sliver also known as a fuse, is practically torn open. The full width of the sliver hits the corresponding "obstacle". This affects the quality, especially the uniform structure of the sliver; the sudden train continues jerkily into the feed area. The tape density is impaired. By unraveling the sliver, the sliver channel becomes clogged very easily.
  • a separating device of this type is not yet satisfactory from the perspective of careful cutting.
  • this device is also structurally disadvantageous because the sliver separating device is arranged above the pitcher head. This creates a space-consuming superstructure and impairs access, especially cleaning.
  • US Pat. No. 3,354,513 discloses a sliver cutting device in which the separating element is designed as scissors. As possible today at full production speed the can change should take place, the US Pat. No. 3,354,513 does not meet these requirements. When changing at full speed, 10-20m sliver is placed between the cans. The cutting plane is also transverse to the direction of the sliver conveying.
  • One scissor blade is arranged in a fixed position and is undermined by the sliver.
  • the other scissor blade is pivotally assigned to this first scissor blade.
  • the separating effect should also be disadvantageous in the same way as set out above, if the corresponding separating cut does not have to take place at all with the belt standing still. But that reduces the economic utilization.
  • the separating element which also acts here in a transverse plane to the course of the thread strand, is designed in the form of a title-shaped separating knife, which linearly travels into an elongated cutting channel as it passes through the thread strand channel, which is separated from an upper and underside of the contact edge is limited to prevent evasion when cutting.
  • This cutting knife suddenly moves in due to a spring-loaded piston / cylinder control unit.
  • the sliver is drawn through the calender rolls. If the sliver is now separated from the rollers, further transport is not safe. There is a malfunction.
  • the object of the present invention is to provide a pitcher with sliver separation device which has practically no effect on the sliver travel, so that the quality of the sliver is not impaired and it is even irrelevant whether the fuse is a short-fiber web of vegetable, animal type or and especially it is one of endless or long filaments acts like synthetic fibers.
  • the fiber sliver is cut safely and quickly. No repercussions like the explained jerking etc. occur.
  • the fiber structure is not subject to spontaneous stress.
  • the tape density is no longer adversely affected. Rather, the result is a smooth, even run.
  • the thread cross-section therefore does not strike the cutting edge bluntly; rather, the pulling cut results in a cutting action which is distributed over a range of rotation angles, that is to say only gradually deepens.
  • the sliver runs onto a continuously increasing cutting ramp.
  • the belt also rotates under the cutting action due to the rotation of the Kannenstock turntable.
  • the sliver is cut off smoothly.
  • the blade of the cutting knife is pivotally mounted on the machine frame at one end about a vertical bolt and is connected to a drive device for its displacement. The corresponding pivotability of the blade favors the use of an extremely short actuation stroke due to the use of leverage. The blade can be quickly inserted and removed.
  • the drive device is advantageously implemented as a piston / cylinder unit, the piston rod of which acts at a distance from the pivot axis of the cutting knife, the cutting knife in the cutting position extending up to a radial of the orbit, which radial is essentially perpendicular to the cutting knife cutting edge.
  • the development is characterized by an acute angle between the cutting edge and the head surface of the separating knife pointing in the circumferential direction.
  • the corresponding undercut can be chosen to be so large-angled that when the last fibers are severed, more than 2/3 or even almost the entire cross section of the outlet channel is open again.
  • the piston rod of the piston / cylinder unit it also proves to be advantageous for the piston rod of the piston / cylinder unit to run approximately parallel to the radial, ie to extend essentially perpendicular to the cutting knife edge. This leads to an actuation direction that is optimal in terms of force. Furthermore, there is an advantageous embodiment by a proximity switch activating the piston / cylinder unit, which receives its pulse from a turntable or rotating ring-side trigger. In addition, it proves to be advantageous in this context that the separating device functions depending on the activation of the proximity switch and the position of a jug for receiving the sliver. That represents a committee-free, fully automatic operation safe.
  • an advantageous alternative solution to the cutting knife assignment is that the cutting edge of the cutting knife that provides the pulling cut is arranged on the outward-facing side of the cutting knife, that is, further away from the center of the orbit, and the cutting knife tip points counter to the direction of rotation.
  • the fiber sliver thereby overflows a practically hook-shaped separating device.
  • the sliver inevitably overflows the cutting edge. No fibers can escape.
  • Another advantage of this version is that the cutting pressure does not work against the pressure medium of the piston / cylinder unit, but is absorbed by the rigid end stop of the cylinder.
  • Another advantage of this solution is that the fiber and dust residues are conveyed out of the groove by the separating knife that has entered.
  • the separating knife which acts like a shovel or plow, works in a self-cleaning manner, the discharge of said residues being additionally supported by the centrifugal force. It is also advantageous that the cutting knife tapered towards the free end. Accordingly, no particularly deep transverse groove needs to be cut into the turntable. Taking into account the spatial requirements for the pivoting movement of the cutting knife, an embodiment has proven to be advantageous in that the sharpening angle is 10 ° and the side of the cutting knife facing the center of the orbit includes an angle of 90 ° to the radial (deposit radius) in the cutting position .
  • the can holder 1 integrated in a linear changer has a turntable 2. The latter rotates in the direction of the arrow x.
  • a sliver 3 fed to the can stick 1 is placed in a can 4 in an orderly manner.
  • the latter stands on a turntable 5 in the bottom 6 of the can stick 1.
  • the deposit takes place in a ring in an increasing manner, whereby due to the rotation of the turntable 2 and an eccentrically arranged passage opening 7 for the fiber sliver 3, a helical position, as shown in FIG. 8, results.
  • the passage opening 7 is formed by a nozzle 8 which is directed upwards and adjoins this vertically downward an outlet channel 9 which runs partly in the material of the turntable 2 and is partly formed by a tube 10 arranged above it.
  • the downward-facing end section of the nozzle 8 extends deep into the gusset of two calender rolls 11.
  • the calender rolls 11 mounted in the pot-shaped turntable 2 pull the fiber sliver 3 downwards and push it through the smooth outlet channel 9 onto the underside of the jug head.
  • the upper end of the tube 10 is designed accordingly.
  • the drive of the calender rolls 11 is derived from the rotary movement of the turntable 2. This has been realized Belt drive.
  • the elements forming it, like the calender rolls, are accommodated in the pot space of the turntable 2, which is covered by a cover 12 at the top.
  • the tapping of the rotary movement takes place via a friction wheel 13.
  • the latter rolls on the ring surface 14 'of an annular body 14 which is arranged in a fixed manner in the can end of the can.
  • the friction wheel 13 is loaded by the belt tension in the direction of contact. It sits on a handlebar 15 which pivots about an axis 16. The latter extends from the bottom 2 'of the pot-shaped turntable 2. The wall of the pot is called 2 ''.
  • the pivot axis carrying the friction wheel 13 bears the reference numeral 17. It is extended upwards for the attachment of a belt pulley 19 which transfers the rotary movement of the friction wheel 13 to a drive belt 18.
  • the belt drive comprises six further deflection belt pulleys.
  • the lower end of the Kannenstockkopf forms a centrally mounted disk 25. This is freely rotatable and coincides with the bearing axis of the central pulley 20 and can be curved flat downwards.
  • the ring outer surface 14 ′′ opposite the ring surface 14 ′ of the ring body 14 accommodates a wire ring bearing 26, via which the turntable 2 receives its bearing in the pitcher head by means of a bearing ring 27.
  • the friction wheel 13 extends through a window 2 ′′ ′′ in the jacket wall of the pot-shaped rotary plate 2.
  • a sliver separation device TV is assigned to the can 1 in the area of the can head.
  • This has a cutting knife 28. Its storage is designed in such a way that the knife edge 28 'for the separating process moves from a free, that is not yet tangent, rest position into a cutting position lying in the orbit U of the outlet channel 9 transversely to the strip longitudinal extension.
  • the turntable 2 has a horizontally running transverse groove 29 approximately at the level of the underside of its base 2 '. The latter is pierced all the way round and is located in a downward, annular web-like thickening 30 of the turntable base 2 '.
  • the thickening corresponds approximately to the material thickness of the plate base, on the inside. The thickening is used to form the vertically aligned, cylindrical outlet channel 9.
  • the sliver separation device TV is located on the side of the periphery of the turntable 2 having the outlet channel 9.
  • the blade of the separating knife 28 pivots at one end about a vertical bolt 31. It is a stay bolt that starts from the machine frame, here the press plate 32 of the can end.
  • the cutting knife 28 moves with the aid of an electrically or electronically controlled drive device 33 from the rest position into the active cutting position and back.
  • a drive device is used, which is implemented as a pneumatic piston / cylinder unit. Its piston rod 34, spaced from the pivot axis (vertical bolt 31) of the separating knife 28, articulates on the latter. It is an indirect attack as a result of the interposition of an angular actuating part 35 made of flat material. Its longer angle leg slides on the top of the press plate 32 and projects into the relatively narrow gap area Sp between the edge-side section of the base 2 'of the turntable 2 and the outside in front of it extending, slightly higher ring body 14. The shorter, vertical angle leg of the actuating part 35 forms the attachment point for the free end of the piston rod 34.
  • the latter has an external thread 36. Two nuts 37 allow fine adjustment of the actuating part 35 for exact adjustment of the separating knife 28.
  • the hinge pin between the actuating part 35 and the separating knife 28 bears the reference number 38 and is seated approximately half the length of the blade, slightly displaced on the back of the blade.
  • an elongated hole would be formed in this area Compensate for movement needs; otherwise, it is sufficient if the cylinder 39 of the drive device 33 were articulated about a vertical axis.
  • this alternative is not shown.
  • Preferred is the first-mentioned type of assignment with a correspondingly fixed assignment of the cylinder 39 to a vertical bracket 40 which is firmly connected to the press plate 32.
  • the cutting edge 28 ′ is essentially perpendicular to an imaginary radial R of the turntable 2, which cuts the cutting knife tip 28 ′′ radially.
  • the corresponding angle alpha between the radial R and the cutting edge 28 ' is 95 °.
  • a corresponding angle of approx. 82 ° results in the release position.
  • the head surface 28 ′′ ′′ of the cutting knife 28 pointing in the direction of rotation x is designed here to be fleeing.
  • the relevant acute angle beta based on the radial R as the base, is approximately 15 °. This has the consequence that the cover field F is shortened in the cutting phase by this bevel.
  • the cover field F is shown in FIG. 6 by means of a contour. It is determined on the inside and outside edge by the circular-arc-shaped edges of the orbit U on the one hand and on the knife side by the cutting edge 28 'on the other hand.
  • the piston rod 34 runs approximately parallel to the radial R.
  • FIG. 5 The immersion of the fiber strand cross-section (defined by the circular cross-section of the outlet channel 9) into the cutting zone of the separating knife 28 is clearly shown in FIG. 5.
  • the inlet is strikingly acute.
  • the sliver cross-section overflows the cutting edge 28 'facing the center of the circular orbit U and after about one round trip of about 1 1/2 times the size of the outlet duct cross-section is compressed in half and partially severed (position b). After a further section of the path in the direction of arrow x by approximately the same amount, the sliver cross section has already been cut apart to a small remaining amount (position c).
  • the exact engagement of the separating knife 28 takes place in motion-dependent control or triggering, specifically by means of a proximity switch 41 which activates the piston / cylinder unit (cf. FIG. 3).
  • the latter receives its impulses from a trigger 42 on the turntable.
  • This and / or the proximity switch 41 can be ascertained in a precise position.
  • the trigger 42 has a radially directed elongated hole which is penetrated by the shaft of a retaining screw 43.
  • the sliver separation device TV comes into operation depending on the activation of the proximity switch 41 and the position of the can 4 for receiving the sliver 3, which position is detected by a corresponding switch or button (This is explained in more detail below).
  • the strip separation is thus controlled electrically. If necessary, it can be computer-controlled.
  • the cans are changed by means of the device shown in detail in FIG. 1, which has a track 45 for the cans 4 indicated by dash-dotted lines, which adjoin a bracket 46 on one side.
  • a can displacement unit 49 is arranged between the end walls 47 and 48 of the console 46.
  • the can displacement unit 49 has a piston / cylinder unit 56, a polygonal profile 57, a longitudinally displaceable but non-rotatably mounted support piece 53 on the polygonal profile 57 and arms or grippers 44 fastened to the support piece 53.
  • the free end of the piston rod 58 of the piston / cylinder unit 56 engages a tab 59 of the can displacement unit 49.
  • Bearings 50, which support the polygon profile 57, are located on the side walls 47 and 48.
  • the polygon profile 57 can be pivoted via a pivoting lever 52, so that the arms or grippers 44 attached to the support piece 53 move from their downward-pointing vertical position into a lifting position (according to FIG. 1) and can be returned.
  • the grippers 44 have a distance from each other which corresponds approximately to the outer diameter of a can 4.
  • An electrical switch 54 shown only schematically, is arranged in the horizontal displacement path of the support piece 32.
  • a limit switch 60 or 61 is provided in each of the two end regions of the cylinder of the piston / cylinder unit 56, these likewise only being indicated schematically.
  • the switches 54, 60 and 61 trip according to the position of the support piece 53 and can be operated mechanically or by approach (preferably reed contacts can be used, which are triggered by the magnetic piston of the piston / cylinder unit 56).
  • the switch 54 is slidably supported in the direction of the double arrow 55 and can be set in the desired position. As a result, its response to the position of the can displacement unit 49 can be adjusted.
  • the limit switches 60 and 61 have the task of monitoring the horizontal displacement path of the can displacement unit 49.
  • the end positions correspond to the takeover position of a new can 4 which has not yet been filled or the shift position assigned to the turntable 5.
  • the device now works as follows: It is assumed that the piston / cylinder units 56 and 51 have assumed the positions shown in FIG. 1, the can 4 located on the turntable 5 being filled with sliver. In the course of this filling process, the piston / cylinder unit 51 is actuated in such a way that the polygon profile 57 rotates around the bearings 50, as a result of which the grippers 44 move into their vertically downward position. Then - triggered by a not shown Control unit - the support piece 53 shifted in the direction of the end wall 48, into a position which corresponds to the waiting, empty can 4. This displacement is brought about by the piston / cylinder unit 56, the force being transmitted via the piston rod 58 and the plate 59.
  • the grippers 44 are then brought back into the lifting position by means of the piston / cylinder unit 51, so that they take up the still empty can 4 between them. If it is now determined by suitable means (for example by counting the number of revolutions of the can) that the can 4 subjected to the filling process comes closer to its filling position, the control unit causes the piston of the piston / cylinder unit 56 to be displaced in the direction of the end wall 47 so that over Piston rod 58 and bracket 59, the support piece 53 and thus the can 4 to be filled is carried along via the arms 44, as a result of which the already filled can 4 is moved out of the device to the right (cf. FIG. 1). The horizontal displacement of the grippers 44 takes place until the new can 4 assumes its position on the turntable 5.
  • suitable means for example by counting the number of revolutions of the can
  • the switch 54 is actuated, which brings about a kind of "arming". This means that at the moment when the proximity switch 41 is activated due to the proximity of the trigger 42 and at the same time the arming has been carried out by the switch 54, the drive device 33 receives a trigger pulse. The separating knife 28 is thus advanced into the cutting position. The retraction of the knife takes place as a function of the rotational speed of the passage opening 7, ie, as already explained above, in a period of time for the advance moment of the knife which is less than or at most equal to a round trip time of the passage opening 7. It is clear from the preceding explanations that the time of the band separation can be set by means of the positioning of the switch 54 along the double arrow 55. The position of the switch 54 defines the positions of the filled or to be filled can 4 at the time of the cutting process.
  • a further advance of the cutting time relative to the can positions can be realized to such an extent that the end of the band of the filled can remains on the sliver holder, i.e. does not hang outwards, while the beginning of the band formed then hangs far over the edge of the can 4 to be filled.
  • the desired sliver protrusion or the remaining sliver end or sliver start can be set in the respective can.
  • the rotational speed of the passage opening 7 is not reduced by the cutting of the sliver according to the invention during the cutting process or the can changing process needs to be. This enables quick operation. Furthermore, the constant rotational speed of the passage opening 7 (and thus the constant delivery speed of the sliver 3) ensures that there are no losses in production or quality.
  • Another advantage is that the separating knife 28 is held interchangeably, so that a remedy can be quickly provided in the case of a blunt knife or a knife break.
  • the invention is not limited to the linear changer for the cans 4 shown in FIG. 1, but it can also be used, for example, in so-called turret changers.
  • the cans 4 are not guided linearly but on a circular path.
  • the variant of the cutting knife 28 according to the invention shown in FIG. 10 realizes the same advantageous principle as explained in relation to the drawing cut as explained for FIGS. 1-9.
  • the reference numbers are used analogously, but without repeating the relevant text in detail.
  • the cutting edge 28 'of the cutting knife 28 now lies on the outward-facing side of the cutting knife 28, that is to say farther away from the said center of the orbit U.
  • the separating knife 28, which also pivots about a fixed articulation point 31, can be finely adjusted according to a correspondingly adjustable support for the vertical bolt 31 forming the swivel axis or articulation axis.
  • the actuating part 35 which is explained in detail above and above, extends practically parallel to it said piston / cylinder unit is moved. It is interesting that the cutting pressure acting on the cutting edge 28 'of the separating knife 28 no longer acts against the medium loading the piston of the piston / cylinder unit. The cutting pressure is rather absorbed by the rigid end stop of said cylinder. In order to get by with a relatively small swivel stroke, the separating knife 28 is tapered towards its free end.
  • the corresponding tapering angle is approximately 10 °, the side of the cutting knife 28 facing the center point of the circular orbit U including an angle of approximately 90 ° to the radial (deposit radius) in the cutting position (FIG. 10).
  • a very short working stroke is sufficient for the piston / cylinder unit.
  • the tapering is continuous and begins in the area of the hinge pin 38.
  • the tapering also results in an extreme undercut 28 '''in the head surface, which opens the cross section of the sliver largely in the direction of conveyance (transport direction of the sliver) right from the start.
  • the non-active cutting position of the cutting knife 28 is shown in dash-dotted line in FIG. 10.
