Definitions
- the invention relates to a tongs unit of a combing machine with a reciprocally movable tongs frame, which has a lower tongs plate and with an upper one mounted in the tongs frame via lateral pivot arms
- Forceps plate which can form a clamping point with the lower forceps plate in the area of the forceps plate lip and with a feed cylinder mounted above the lower forceps plate in bearing receptacles of the forceps frame.
- DE-4216485 shows and describes such a forceps unit of a combing machine which reciprocates via swivel arms.
- a forceps unit of a combing machine which reciprocates via swivel arms.
- the upper pliers plate is pivotally mounted on the pliers frame via swivel arms.
- a spring strut is attached to the respective swivel arm via a hinge point, which is mounted at the other end on a driven eccentric.
- the feed cylinder shown in the tongs unit is mounted on the side in bearings in the tongs frame. If the feed cylinder has to be removed (e.g.
- the invention is therefore based on the object of eliminating these disadvantages and proposing an embodiment of a forceps unit, the accessibility for the expansion of the feed cylinders being substantially improved.
- This object is achieved in that it is proposed that the lateral pivot arms of the forceps plate are arranged or designed such that they are outside the area which the feed cylinder traverses when it - transversely to its axis - from an operating position to an out-of-operation position is transferred.
- This enables the feed cylinder to be freely accessible in the forceps unit.
- the feed cylinder can be easily moved from its operating position to an out-of-service position in any position of the tongs, without the need to move the top tongs plate with its swivel arms to another position using special tools.
- relocation of the feed cylinder means the feed cylinder including its bearings and other components which have to be moved during the relocation in order to bring it into an out-of-operation position.
- operating position includes the fixed position of the feed cylinder, in which it forms a conveying gap in cooperation with the tongs plate 12, or with a feed trough mounted therein, in which an interposed wad of cotton is transported by rotating the feed cylinder.
- area which the feed cylinder traverses when it is shifted from its operating position into an out-of-service position is essentially to be understood as the space through which the feed cylinder is passed on its way into this position.
- the free accessibility is guaranteed if the swivel arms of the top tong plate run below the bearing receptacles of the feed cylinder.
- a spring strut provided with a spring element is hinged to the swivel arms, the other free end of which is mounted at a fixed pivot point in the machine frame, the spring strut being designed so that a clamping force in the area of the tong plate lip between the upper and lower pliers plate is generated when the pliers unit is in a rear
- the fixed pivot point of the respective shock absorber can advantageously be arranged below the pliers assembly.
- the bearing receptacles of the feed cylinder have an opening at the top, the clear width of which is at least the diameter of the bearing of the feed cylinder inserted in the bearing receptacle, and means are provided in order to close the opening. This ensures simple and quick disassembly or assembly of the feed cylinder or feed cylinder.
- the release of the locking of the feed cylinders is simplified if the means for closing the opening are mounted so as to be pivotable about an axis fastened in the forceps frame.
- the means can consist of a pivotable two-armed lever, a first arm being displaceable for overlapping with the opening and a second arm being pivotable into the effective range of a spring element.
- the spring element consist of two sleeves, a first sleeve being fastened to the tong frame and receiving a compression spring and a second sleeve, which is closed on one side, in the region of the open side on the first sleeve to be led.
- a radially projecting tab can be provided on the second sleeve, with which the handling is facilitated.
- FIG. 1 shows a schematic side view of a pliers unit of known type.
- FIG. 2 shows a schematic side view according to FIG. 1 with the attachment of the swivel arms of the upper pliers plate designed according to the invention.
- FIG. 3 shows a view X according to FIG. 2.
- FIG. 4 shows another embodiment of Figure 1 with swivel arms designed according to the invention.
- 5 shows a schematic side view according to FIG. 4
- Figure 1 shows a pliers unit 1, which is pivotally mounted on the crank arms 2, 3.
- Two crank arms 2 are each pivotally mounted on the side of a round comb 4 on its round comb shaft 5.
- the other end of the swivel arms 2 is rotatably attached to the tong frame 8.
- the rear swivel arm 3 (there may also be two) is rotatably mounted on a pliers shaft 10.
- the opposite free end of the swivel arm 3 is rotatably connected to the pliers frame 8 via a shaft 9.
- the pliers assembly 1 essentially consists of a lower pliers plate 12 firmly connected to the pliers frame 8 and an upper pliers plate 14 (sometimes also called a pliers knife) which is attached to two pivot arms 15, 15 '. These pivot arms are pivotally attached to the pincer frame 8 via a pivot axis 16.
- the swivel arms 15, 15 ' are each connected to a spring strut 18, which in turn is mounted on a driven eccentric 21 via an axis 20.
- a tear-off cylinder pair 24 is provided behind the pliers unit.
- a feed cylinder 27 is rotatably mounted within the forceps unit 1 and carries out a discontinuous rotary movement via a drive (not shown in more detail) in order to transport the supplied cotton wool W in sections.
- the feed cylinder 27 has a shaft 28, via which it is rotatably supported on both ends via bearings 29 in bearing receptacles of the forceps frame (not shown here). With this arrangement it is necessary - as already described in the introduction to the description - to swivel the upper tong plate via the swivel arms 15, 15 'into a rear position indicated by dash-dotted lines in order to replace the feed cylinder 27.
- FIG. 2 To remedy these disadvantages, an embodiment according to FIG. 2 is proposed, which will now be explained in more detail.
- the swivel arms 15a of the upper tong plate 14 run below the bearing holder 26 of the feed cylinder 27.
- the swivel axis 16 of the swivel arms 15a is also fitted below the bearing holder 26. This ensures that there is a sufficient swivel range for the swivel arms 15a to carry out the necessary swivel movement.
- the area above the feed cylinder is completely freely accessible, which means that the feed cylinder can be removed quickly and easily.
- the spring struts 18a which act laterally on the pivot arms 15a via the axes 23 (see FIG. 3), are pivotably mounted on an axis 34 which below the tear-off cylinder 24 is attached to the machine frame. This allows the space above the feed cylinders to be kept completely free. If such an attachment of the spring struts is provided, another drive arrangement (not shown) for the pliers assembly would also be possible.
- the pliers unit could be driven, for example, from the circular comb axis. However, this is not decisive for the claimed design.
- the opening 31 of the guide 38 is covered in the position shown by the arm 33 ", which is part of a two-armed lever 33, which is pivotally mounted about the axis 30 in the tongs frame 8.
- the second arm 33 'of the lever 33 lies approximately at right angles to the arm 33 "and is acted upon by a spring element 40, whereby the arm 33' against the surface of the bearing seat 26 in the area the opening 31 is pressed. This ensures that the feed cylinder 27 remains in its installed position during operation.
- the spring element 40 consists of a sleeve 41 which is attached to the tong frame 8. Another sleeve 42, which is provided with a tab 46, is guided coaxially on the sleeve 40. A spring 44 is guided within the sleeve 41, which rests on one end on a bolt 45 of the sleeve 41 and on the opposite end on the inner wall of the end 49 of the sleeve 42.
- a lever 47 is fastened in a rotationally fixed manner and is connected to a drive (not shown in more detail).
- this drive could take place from a main drive shaft via a correspondingly designed articulated gear which interacts with a cam disk.
- GB-PS 933,946 One possible version is e.g. from GB-PS 933,946.
- the sleeve 42 is moved backwards against the spring force of the spring 44 via the tab 46.
- the arm 33 'of the lever 33 is released and can be pivoted about the axis 30 in the clockwise direction.
- the opening 31 is cleared, with which the feed cylinder or its bearing 29 can be withdrawn upward from the guide 38.
- the lever 33 is pivoted counterclockwise with the sleeve 42 pushed back simultaneously until it rests on the surface of the bearing receptacle 26 and thus closes the opening 31 again.
- the sleeve 42 can also be moved to the left with the spring force of the spring 44 until the end 49 comes to rest on the arm 33 '. It is also possible, if necessary, to fix the spring element 40 in this position with an additional locking device (not shown) in order to prevent the lever 33 from being released automatically. The locking of the feed cylinder 27 in its working position is now complete.
- the drive element 47 can now be coupled again, making the system ready for the combing process again.
- FIG. 4 and 5 show a further exemplary embodiment, in contrast to the previous exemplary embodiment the pivot arms 15d, 15e being arranged above the tong plate 12 and being able to pivot about an axis 16 in each case.
- the two swivel arms 15d, 15e have an internal width L to one another which is greater than the length B of the feed cylinder 27 including its bearings 29 and the lever 47 articulated on the feed cylinder.
- This lever 47 is only indicated schematically and is responsible for driving the feed cylinder.
- a freewheel can be provided between the axis 28 of the feed cylinder 27 and the lever 47, via which a discontinuous drive movement is generated.
- the lever can be part of an articulated gear, not shown, which has a roller which is guided on a cam disk, which is connected in a rotationally fixed manner, for example, to the circular comb axis. It is also conceivable to provide a drive with a freewheel on both ends of the feed cylinder 27 in order to carry out a mixed feed in the feed and return flow of the tongs. Such an arrangement can be found, for example, in US Pat. No. 3,400,431. In this case, the clear width L must be chosen to be large enough so that when the feed cylinder is moved, the opposite drive element within the clear one Width L is. There are of course other possible drive options for the feed cylinder, as can be seen from the known literature.
- the design of the swivel arm 15e is (as an example) designed somewhat differently than the design of the swivel arm 15d; It is important for the displacement of the feed cylinder 27 that this in any position or position of the
- Pliers 1 can be shifted from its operating position without the pivot arms 15d, 15e hindering this shift.
- the term "relocation" can on the one hand transfer the feed cylinder 27 into a maintenance position. Position for threading a new cotton wool W or include the complete removal from the forceps unit.
- the maintenance position described above is indicated by dash-dotted lines in FIG. 5.
- the drive (freewheel) to the feed cylinder is of course not released, but rather moved with the feed cylinder to the position shown in dashed lines.
- the drive of the pliers unit 1 is initiated via a drive rod S articulated on the pliers frame 8 on the shaft 9.
- the struts 18 are attached above the tong frame 8.
- an attachment below the pliers frame would also be possible, as described and shown in FIG.
- the feed cylinder 27 can also be locked via a two-armed lever 33, as in the example in FIG.
