Definitions

  • the present invention relates to a card with an inlet side for fiber flakes, the card being designed to feed the fiber flakes to a rotating drum by means of at least one licker-in.
  • the fiber flakes are broken up, aligned and cleaned down to the individual fibers between fixed carding elements and rotating flat bars.
  • the resulting fibrous web is transferred from the drum to a recipient, which is followed by a device for converting the fibrous web into a sliver.
  • revolving flat cards which essentially have a large main cylinder, the drum or the reel, on which carding of fibers takes place by a certain number of revolving flats and fixed carding elements.
  • the work organ that supplies the material is the licker-in and the work organ that removes the material is the buyer.
  • the carding length and in particular the number of engaged circumferential flat bars of the revolving flat has a significant influence on the carding quality.
  • the carding area and the speed of the drum are crucial for the productivity of the card. It is possible to increase the drum speed, although very high centrifugal forces occur here, which lead to a convex deformation of the drum.
  • the common method is to move the licker-in and/or doffer further under the drum. The usable circumferential length is thus increased in order to be able to accommodate a desired number of additional revolving lids.
  • the drum must be positioned very high in the machine, at least high enough to be above the doffer.
  • the running stability and vibration stiffness become worse the higher the heavy and high-speed drum is positioned at approx. 600 rpm.
  • the supporting frame construction must be appropriately large and strong and must not be too slim.
  • Increasing the carding length and the drum diameter also changes the geometry of the frame on which the drum with the doffer and the licker-in unit are arranged and stored.
  • the dimensions of the frame are higher and wider, so that the effort required to process the cultivated areas increases with the existing machinery.
  • the frame cannot be processed in one clamping operation with the existing machines, but must be repositioned and clamped several times on the machine tool tables. The manufacturing costs increase significantly.
  • EP 2527505 discloses a revolving flat card, which proposes a certain geometric arrangement of licker-in and doffer to achieve high productivity.
  • the entire geometry is based on a horizontal orientation of the card.
  • the frame provides a central receiving surface for storing the reel, with receiving surfaces for the licker-in unit and the doffer being arranged on both sides.
  • the length of the construction is therefore very large and requires a processing machine with a large clamping area. If the card is to be manufactured at several locations worldwide, these locations must all have processing machines with this large clamping area.
  • the invention is based on the object of developing the frame of a carding machine in such a way that it can be produced on processing machines of different sizes with, if possible, only one clamping device.
  • the invention relates to a card with an inlet side for fiber flakes, the card being designed to feed the fiber flakes to a rotating drum by means of at least one licker-in.
  • the fiber flakes are broken up, aligned and cleaned down to the individual fibers between fixed carding elements and rotating flat bars.
  • the resulting fibrous web is transferred from the drum to a recipient, which is followed by a device for converting the fibrous web into a sliver.
  • the invention includes the technical teaching that the card has a frame for holding the drum and the doffer, and that the at least one licker-in is on or in is arranged and stored in a separate housing, the separate housing being arranged and fastened to the frame in such a way that the distance between the at least one licker-in and the drum is adjustable.
  • the card frame By separating the licker-in assembly with all attachments, drives and suction units from the card frame, the card frame can be made shorter. This makes it possible to produce the frame with just one clamping on different processing stations, which reduces manufacturing costs.
  • the adjustable arrangement or attachment of the housing with the assembly of the licker-in to the frame of the card has the further advantage that the distance between the drum and the adjacent licker-in can be adjusted depending on the material to be processed, the operating temperature and / or the state of wear of the clothing .
  • the transfer of the pre-cleaned fiber flakes or fibers from the licker-in to the drum is optimized so that the card works with higher productivity.
  • the housing Depending on how the housing is arranged in an adjustable manner on the frame, its position relative to the frame can be adjusted using an actuator.
  • the actuator can be designed to move the housing to the frame of the card, for example along a guide or to pivot about a pivot point.
  • the housing can be pivotably arranged on the frame results in a fixed pivot point which serves as a fixed bearing.
  • the distance between these two rollers can be adjusted by pivoting the housing around this pivot point.
  • the transfer gap between the drum and the adjacent licker-in can be adjusted with high precision.
  • a support can be arranged between the frame and the housing and is designed to pivot the housing about the pivot point.
  • the support can be designed mechanically and can be adjusted manually, or can be designed as an actuator, whereby the housing is pivoted, for example by a motor, at a distance from the frame. This makes it possible to adjust the transfer gap between the drum and licker-in during operation, which can be varied, for example, when the operating temperature changes.
  • the support can interact with a vertical side part of the frame below the pivot point. This means that the weight of the housing always acts on the support around the pivot point, so that dead play or free play, for example in a screw thread of the support, is always avoided.
  • the transfer gap is always adjusted precisely.
  • the at least one licker-in can be stored in a bearing that is open at the top in the housing. Without dismantling the associated components, the licker-in can be dismantled very quickly and fitted with a new set.
  • the at least one licker-in works together with a fixed carding element, which are also attached to the housing.
  • the fixed carding elements can be arranged above or below the licker-in.
  • lateral mounting openings can be arranged on the housing, through which the fixed carding elements can be adjusted at a distance from the associated licker-in.
  • a higher separation of impurities and a better dissolution of the fiber flakes can be achieved if the housing has three lickers that are arranged in bearings that are open at the top.

  • Figure 2 a frame of a card according to the prior art
  • Figure 3 a card frame according to the invention with the licker-in unit
  • Figure 4 another enlarged view of the licker-in unit.
  • Fig. 1 shows a card according to the prior art, in which fiber flakes are guided via a shaft to a feed roller 1, a feed table 2, via several licker-ins 3a, 3b, 3c, to the drum 4 or the reel.
  • the fibers of the fiber flakes are parallelized and cleaned using fixed and rotating carding elements.
  • the resulting fibrous web is subsequently conveyed via a pickup 5, a stripping roller 6 and several squeezing rollers 8, 9 to a fleece guiding element 10, which forms the fibrous web with a funnel 11 into a sliver that is fed via take-off rollers 12, 13 to a subsequent processing machine or a Pot 15 hands over.
  • the removal of the fibers from the customer 5 is supported by a fleece guide profile 7, which is arranged below the stripping roller 6.
  • a cleaning roller 6a Above the stripping roller 6 there is a cleaning roller 6a, with which fiber residues are removed from the stripping roller 6 and fed to a suction device (not further specified).
  • Figure 2 shows a frame 18 of a card according to the prior art.
  • the central component is the receiving area 18a for the drum, which in this illustration is adjoined on the left by the receiving area for the doffer 18b and on the right by the receiving area for the licker-in 18c.
  • an enlarged frame 18 of the card results, the dimensions of which become higher and/or longer .
  • the frame 18 for machining the mounting surfaces and bearings can no longer be machined in one clamping on the machine tool.
  • the invention provides for the frame 18 to be shortened by the receiving area for the licker-in(s) and to integrate the complete assembly of the licker-in(s) 3a-3c in its own separate housing 19.
  • This housing 19 is rotatably attached to a pivot point 20 of the frame 18 and is adjusted at a distance from the drum 4 by means of a support 21 which is arranged between a side part of the frame 18 and the housing 19.
  • three lickers 3a - 3c are arranged in the housing 19.
  • Alternative assemblies provide the embodiment with only a single licker-in.
  • the housing 19 with the assembly of the lickers 3a-3c is designed to be pivotable about the pivot point 20 - due to its own weight - and is only held in position by the support 21.
  • the housing 19 pivots about the pivot point 20, so that the distance between the sets of the licker-in 3c and the drum 4 can be adjusted.
  • the support 21 can also be completely retracted, so that the distance between the sets of the licker-in 3c and the drum 4 is increased. This makes it easier to redress the licker-ins 3a-3c, as they become easier to access.
  • a distance between 200mm and 300mm between the support 21 and the pivot point 20 has proven to be advantageous. At this distance, on the one hand, a precise adjustment of the licker-in 3c to the drum 4 is possible, and at the same time a compact design can be achieved.
  • the licker-in 3a-3c are arranged in a bearing that is open at the top, whereby all licker-in 3a-3c can be removed from the housing 19 without much assembly effort.
  • the support 21 can be actuated mechanically or via an actuator (hydraulic, pneumatic, electric motor), so that a control can be designed to adjust the gap or distance between the clothing of the drum 4 and the clothing of the card while the card is in operation or when it is at a standstill licker-in 3c.
  • the setting can be made depending on, for example, the material to be processed, the operating temperature and/or the state of wear of the clothing.
  • the housing 19 is designed to accommodate the entire assembly of the licker-ins 3a-3c including feed roller 1, dining table 2, with all associated drives and suction systems 22.
  • the transition to fiber flock feeding takes place via a flexible connection (not shown) in order to compensate for the movement of the housing 19.
  • the licker-in 3c has a fixed carding element 23c, which is arranged vertically below the licker-in 3c in the housing 19.
  • the middle licker-in 3b has a fixed carding element 23b, which is arranged above the licker-in 3b on the housing 19.
  • the licker-in 3a also has a fixed carding element 23a, which is arranged obliquely below the licker-in 3a in the housing 19. Also visible are drives with drive belts and a suction 22, which are all part of the licker-in assembly and are arranged or integrated on or in the housing 19.
  • Figure 4 shows an enlarged view of the second and third licker-in 3b, 3c with the associated fixed carding elements 23b, 23c.
  • the fixed carding elements 23b, 23c can be adjusted at a distance from the set of licker-ins 3b, 3c by adjusting or moving or pivoting the associated spacer elements 25b, 25c, and thus the distance between the carding elements 23b, 23c to set the licker-in 3b, 3c can be varied.
  • the spacing position is then fixed again by the fastening elements 24b, 24c.
  • a housing cutout is arranged in the form of a window through which the fitter can loosen or tighten the fastening element 24c with a tool.
  • the fixed carding element 23b is arranged above the licker-in 3b.
  • the fastening element 24b is exposed and can be loosened or refastened after the fixed carding element 3b has been adjusted.
  • a spacer element 25b is arranged between the fixed carding element 23b and the licker-in 3b, so that the distance of the fixed carding element 23b to the clothing of the licker-in 3b can be adjusted by moving or pivoting the distance element 25b.
  • Both spacer elements 25b, 25c are accessible through windows in the housing 19.
  • the design described here is arranged on both sides of the card, so that the distances to be set can always be set over the entire working width of the card.
  • This improvement has the advantage that the distances between the fixed carding elements and the associated licker-in rollers can be adjusted without dismantling the suction hoods, profiles or other components, in that the fastening elements and the spacer elements are accessible through windows arranged in the housing. All components remain in place without dismantling when adjusting the fixed carding elements.
