Definitions

  • the invention relates to a nonwoven carding machine for the nonwoven production of fiber material according to the preamble of claim 1, and to a method for producing a nonwoven fabric from fiber material according to the preamble of claim 7.
  • Such a fleece card is for example from the EP 484 812 A known.
  • a fibrous web are each removed from a master cylinder with the help of two fiber removal devices and placed on a conveyor belt in each case with the aid of upsetting and removal rollers.
  • the conveyor belt of a fiber removal device transmits a batt on a conveyor belt of another fiber removal device, so that finally all batt on a common conveyor belt can be transported away as a nonwoven.
  • the decrease of two batts is provided by the master cylinder, wherein the bobbins are relined on a common subsequent roll.
  • From the GB 962162 goes out a device that is to replace a doffer cylinder or the like in a card.
  • This device allows the removal of a single batt from the main drum by means of a fan, with which the fibers are removed from the set of the main drum.
  • the leached fibers are deposited on an evacuated fabric tape which feeds the single pile of fibers to the next carding roll.
  • the fabric tape is vacuumed at the transfer point.
  • the invention has for its object to improve the transmission of multiple removed batt on a common conveyor belt and to allow a more compact construction of a fleece card.
  • the invention advantageously provides that a permeable, endlessly circulating conveyor belt of a transport device wraps around a rotating screen drum at least in the area of the transfer sections of the transport surface, wherein the at least two batt on the common conveyor belt of the transport device can be stored as a nonwoven.
  • the invention provides a removal system in which a guided transfer of individual bobbins is made possible on a common conveyor belt.
  • the circular cylindrical curved, permeable transport surface allows a more favorable storage angle at the transfer sections.
  • the curved surfaces on the transfer sections facilitate the extraction of the fibers on the take-off roll of the fiber take-off device in connection with the suction of the transport surface in the region of the transfer sections.
  • the superposition of the batt in short successive transfer sections also allows a better connection between the top and bottom pile, as well as a compact design of fleece carding.
  • the circular cylindrical curved transport surface allows a low-distortion transfer of the batt on the conveyor belt, so that higher production speeds are possible.
  • a permeable, endlessly circulating conveyor belt of a transport device wraps around a rotating screen drum at least in the area of the transfer sections of the transport surface and removes the superimposed fibrous webs sucked onto the conveyor belt by the screen drum.
  • the speed of the conveyor belt corresponds to the peripheral speed of the rotating screen drum.
  • the transport device is pivotable about an axis coaxial with the axis of the screen drum, such that the transfer point of the conveyor belt for the common batt is height-adjustable from the transport device to a follower device.
  • the fiber removal means may comprise at least one doffer roller engaged with the master cylinder.
  • the fiber take-off device has at least one whirl roll which is in engagement with the master cylinder and which holds the fiber web on at least transfers a doffer roll.
  • a fiber take-off device or a plurality of fiber take-off devices can each have a random roller, which each take over a batt from the master cylinder. From the respective random roller of a fiber take-off device, the fiber web can be transferred to one or more doffer rollers.
  • Each doffer roll is preferably engaged with at least one subsequent draft roll and one take-off roll or only one take-off roll.
  • the intake device with feed rollers and a licker-in between the licker-in and the master cylinder has at least one co-rotating with the master cylinder and the lickerinside roller.
  • the fibers are transferred from the licker-in at least two ways to the master cylinder.
  • the part of a fleece carding on the pulp removal side shown in FIG. 1 has a draw-in device 2 with the aid of which fibers are transferred to a master cylinder 4.
  • a possible embodiment of a collection device. 2 with Verwrwalzen 3a, 3b can be seen in Fig. 4.
  • Two fiber removal devices 6a, 6b on the fiber pile removal side of the nonwoven carding each take a batt from the master cylinder 4 and transfer it to a screen drum 14, which forms a circular cylindrical curved permeable transport surface 15 and is partially besaugbar inside, so that an air flow, the lateral surface the screen drum 14 flows through in a predetermined segment from the outside to the inside.
  • Each fiber take-off device 6a, 6b consists of a doffer roll 8a, 8b and at least one take-off roll 12a, 12b, wherein at least one upsetting roll 10a, 10b can be arranged between the doffer roll 8a, 8b and the take-off roll 12a, 12b.
  • the screen drum 14 forms a circular cylindrical curved, permeable transport surface 15, to which the transferred from the fiber take-off device 6a, 6b bobbin transferred circumferentially offset transfer sections 15a, 15b can be transferred.
  • the transfer sections 15a, 15b are at the narrowest points between the take-off rollers 12a, 12b and the transport surface 15.
  • the peripheral speed of the screen drum is adjusted at its transport surface in direction and amount to the transfer speed of the batt at the transfer sections 15a, 15b.
  • the screen drum 14 is preferably vacuumed in a segment which extends from the pickup roller 12a to a transfer point between the screen drum 14 and a conveyor belt 16.
  • the boundary of the evacuated area is indicated in the drawings by angle symbols.
  • the advantage of the segmented suction of the screening drum 14 is also that only a small volume of air is required in the case of lateral sealing of the fiber removal device 6a, 6b in order to be able to transfer the batt safely to the transfer points even at high transport speeds.
  • the conveyor belt 16 wraps around the screen drum 14 and is moved at the same speed as the peripheral speed of the screen drum 14. This preferred solution avoids a further transfer point between a screen drum 14 and the conveyor belt 16 and thus enables an even more compact construction of the nonwoven carding machine.
  • Fig. 2 shows an embodiment in which pivotable compression rollers 10a, 10b are shown in a weggeschwenkten position in which they are no longer with the doffer rollers 8a, 8b and the take-off rollers 12a, 12b are engaged.
  • the compression rollers 6a, 6b can be disengaged or engaged with a suitable pivoting device.
  • FIG. 3 shows an exemplary embodiment in which a total of three fiber take-off devices 6a, 6b, 6c are provided, so that a total of three fiber webs on the endlessly circulating conveyor belt 16 in conjunction with the permeable transport surface 15 formed together with the sieve drum 14 at transfer points 15a, 15b , 15c can be stored.
  • the screen drum 14 can be completely sucked instead of segmented. It is understood that the conveyor belt 16 between the separation point of the screen drum 14 to the transfer point 20 to the subsequent machine also in the embodiments of FIGS. 1 to 6 may have on the underside air guide vanes 22, which ensure due to the deflection of an air flow below the conveyor belt for a secure adhesion of the batt on the conveyor belt 16.
  • the transport device with the conveyor belt 16 is pivotable about the axis of rotation of the screen drum 14, so that the height of the transfer point 20 is adjustable to a subsequent machine.
  • louvers 13, eg tubes, as shown in Fig. 3, may be arranged to reduce cross-flows.
  • Fig. 4 shows an embodiment of a retraction device 2 with a feed roller 2a, a roughing roll 2b and a lickerin 2c.
  • a feed roller 2a Between the lickerin 2c and the master cylinder 4, two impeller rolls 3a, 3b are arranged.
  • the random rollers 3a, 3b allow for feeding back on the lickerin, so that the carding performance of the licker-in 2c can be used several times. It is understood that even a single whirl roll 3 can be engaged with the lickerin 2c and the master cylinder 4.
  • the random rollers 3a, 3b rotate in the same direction with the master cylinder 4 and the lickerin 2c.
  • Fig. 5 shows an embodiment in which the upper fiber take-off device 6a has a circlip 3c, which is the only roller of the fiber take-off device 6a with the master cylinder 4 in engagement.
  • the whirling roller 3c rotates in the same direction as the master cylinder 4 and in opposite directions to two doffer rollers 8a, 8b engaged with the whirling roller 3c.
  • the transferred from the master cylinder 4 on the random roller 3c bobbin on two doffer rollers 8a, 8b and from there via take-off rollers 12a, 12b or compression rollers in combination with take-off rollers 12a, 12b on the transport surface 15 of the screen drum 14 and the conveyor belt 16 transmitted.
  • the lower fiber take-off device 6b consists of a doffer roller 8c engaged with the master cylinder 4 and a take-off roller 12c engaged on the one hand with the doffer roller 8c and, on the other hand, transferring the fiber web to the transport belt 16 on the drum 14 ,
  • the lower fiber removal device can also be designed as shown in the other embodiments.
  • Fig. 6 shows a further embodiment in which lower fiber take-off device 6b is designed in approximately mirror image to the upper fiber take-off device 6a.
  • the lower fiber take-off device 6b accordingly has a whirling roller 3d engaged with the master cylinder 4, which splits the fiber web onto two doffer rollers 8c and 8d. It is understood that in this embodiment Also upsetting rollers between the doffer rollers 8a to 8d and the doffer rollers 12a to 12d can be arranged.
  • the diameter of the master cylinder is about 1,200 to 1,800 mm, preferably 1,500 mm, wherein the diameter of the random rollers between 400 and 700 mm, preferably 550 mm.
