Definitions

  • a machine for crosswise depositionoof carded webs and the like which are advanced on a feeder belt onto a continuously driven discharge belt. This latter belt is positioned below the feeder belt and travels in a direction essentially at right angles to the direction of movement of the feeder belt.
  • the machine also comprises two conveyor belts interposed between the feeder belt and the discharge belt and these two belts are driven at the same speed and at a constant tension. Means are provided to advance the carded web on these conveyor belts under forced guidance such that said carded web is deposited on the discharge belt evenly and without formation of folds.
  • a second reciprocating carriage situated at a lower level than the first one, above a discharge belt which is movable at right angles relatively said carriages and onto which the carded webs are deposited in the form of bats.
  • the carriages are driven so as to perform a reciprocating movement between adjustable end positions.
  • the first car riage which is connected to the second carriage in some suitable manner and follows it in the same directions of movements but at half its speed serves as an intermediate station.
  • the speed of the conveyor belt on the upper carriage must be higher when the carriage is moving in the opposite direction relatively its conveyor belt than when the directions of movement are the same.
  • the carded webs are somewhat tensioned when being transferred in the direction of feeding from one conveyor belt to the next one in succession.
  • the different and changing speeds of the belts make it difficult to master such tensioning when the carded webs are to be transferred freely between the various belts, and as a consequence thereof various tensions arise with resultant varying web thickness of the carded web.
  • the bat as discharged from the machine will in addition be at its thinnest in its middle and at its thickest at its longitudinal edges.
  • the present invention relates to a machine for crosswise deposition of carded webs advanced on a feeder belt, onto a continuously driven discharge belt which is positioned below the feeder belt and travels in a direction which is essentially at right angles to the direction of movement of the feeder belt, the machine comprising two conveyor belts for the carded web, these conveyor belts being arranged between the feeder belt and the discharge belt, and an outlet opening for the carded web, which opening is provided on a first travelling carriage adapted to be displaced in a reciprocating manner over the discharge belt in the transverse direction of the latter, an a second travelling carriage.
  • the carded web travels between two belts during a certain part of the transfer operation.
  • the carded web is not, however, locked during the entire transfer since before discharge, it is allowed to be supported freely on the lower run of the belt when the carriage is to theleft of the roller.
  • Such free transfer although limited, is sufficient for the bat to tend to form folds when being transversely deposited on the conveyor belt.
  • To tension the carded web is difficult since the belt must be driven at two different speeds depending upon the direction in which the two carriages are being driven.
  • the frame 1 of the machine shown on the drawings comprise two legs 2 supporting horizontal beams 3, on which run the runner wheels 4 of two carriages 5 and 6.
  • the beams are provided with one roller chain 7 each, see FIG. 5, between the rollers of which engage the teeth of chain wheels 8, these chain wheels being arranged on the same transverse shaft 9 on which the runner wheels 4 are arranged in pairs.
  • the chains 7 and the chain wheels 8 insure that the carriages 5 and 6 are not inclined during their reciprocating movements on the beams 3.
  • the machine also comprises two conveyor belts I0 and II running in parallel over each their drive roller 12 and 13, respectively, which rollers are rotatably journaled at the upper part of the frame 1.
  • the rollers 12 and 13 are positioned in such a way that an' opentop inlet opening 14 is formed between the conveyor belts l0 and II to receive the carded web 15 as the latter is being advanced by means of a feeder belt 16 at the upper part of the machine.
  • belt 10 runs over two pulleys 21 and 22 on the carriage 6 and over to two pulleys 23 and 24 on the carriage 5 back to drive roller 12, whereas conveyor belt 11, having left pulley 20 on the carriage 6, travels over two pulleys 25 and 26 on the latter carriage and over a pulley 27 on the carriage 5 back to its drive roller 13.
  • a steel wire 29 is attached to a carriage 6 at a point 28, said wire running over a pulley 30 at the left end of the frame I as seen on the drawings and extending along the entire length of the frame.
  • the wire runs over a pulley 31 supported at the opposite frame end, further over a pulley 32 on carriage 5 and over two additional pulleys 33 and 34 at the right end of the frame and is attached at point 35 in the frame.
  • a wire tensioning device is indicated at 36 and a spring balance is arranged between this device and frame point 35 to indicate the tensile stress of the wire.
  • a continuous drive belt 37 serves to move the carriages 5 and 7 on the frame beams 3 and said belt 37 runs over a drive wheel 38 at the left end of the frame and over a delinking wheel 39 at the right end of the machine.
  • the belt 37 is driven continuously in one and the same direction as indicated by the arrows 40 and 41.
  • the drive mechanism also includes a clutch 42 on the carriage 6 (see HO. 4)
  • the clutch consists of a compressed-air cylinder 43 which is attached on the carriage 6 so as to incline relatively the vertical plane and whichis provided with a piston 44 protruding at both ends of the cylinder.
  • the piston 44 is at the ends thereof provided with clamp shoes 45, 46, positioned opposite abutment plates 47 and 48, respectively, on the carriage 6.
  • the upper run 37 of the belt 37 runs between the upper clamp shoe 45 and the abutment plate 47. and the lower run 37 runs between the lower shoe 46 and the abutment plate 48.
  • the movement of the piston 44 upwards or downwards forces the upper part 37' or the lower part 37 against the abutment plate 47 or the abutment plate 48, respectively, whereby the carriage is brought to move to the right or the left. respectively, on the supporting beams 3.
  • Reference numbers 49 and 50 designate adjustable impulse means which are provided with buffers and which upon actuation by the carriage 6 at the end position thereof communicate a source of compressed air (not shown) with one end or the other of the cylinder 43 for displacing the piston 44 to the upper or lower end position of the latter.
  • the machine operates in the following manner with the initial position of the various parts of the machine being imagined to be the one shown in HO. 1.
  • the carriage 6 in its left end position has just struck on the impulse means 49 causing compressed air to be introduced at the lower end of the cylinder 43, whereby the piston 44 is forced upwards and the shoe 45 clamps belt run 37 against the abutment plate 47.
  • the carriage 6 is then by the belt 37 driven in the direction of arrow 40.
  • With the aid of the wire 29 which runs over pulleys 30, 31, 32, 33 and 34 also carriage 5 is forced to move in the direction of arrow 40.
  • the latter carriage will however, be able to move at only half the speed of carriage 6.
  • the result is that the conveyor belts l0 and 11 will be kept continuously stretched and at a constant tension.
  • the carded web when leaving the conveyor belt 16 consequently will be advanced continuously through the inlet opening 14 and, with the same evenness and continuity, be discharged out through the outlet opening 51 between the pulleys 21 and 25 on the carriage 6.
  • the carded web 15 is thus supplied as a transverse band down onto a continuously driven discharge belt 52 the direction of movement of which is at a right angle to the direction of movement of the carriage 6.
  • the conveyor belts 10, 11 are suitable formed from continuous fabrics with the warp and weft threads made from some synthetic material. Along their longitudinal edges they are preferably provided with guides which are coordinated with peripheral grooves in the pulleys, providing the required lateral guidance of the conveyor belts.
  • said machine comprising two conveyor belts for the carded web. These conveyor belts being arranged between said feeder belt and the discharge belt, an outlet opening for. the carded web.
  • said opening being provided on a first travelling carriage which is adapted to be displaced in a reciprocating manner over the discharge belt in the transverse direction of the latter, and a second travelling carriage, wherein the improvement comprises adapting the two conveyor belts to be driven at the same speed, an inlet opening formed between the conveyor belts, said inlet opening being arranged to be stationary beneath the outlet end of the feeder belt, means for running the two conveyor belts over pulleys on said first carriage on which said outlet opening is provided and means for adapting said second carriage to be displaced in such a direction and at such a speed relatively the first carriage that the two conveyor belts are held under a constant tension.
  • a clutch comprises a pneumatically operated piston in a cylinder in which said piston is adapted to move in a reciprocating manner, said piston beingprovided at both its ends with a clamping shoe which cooperates with a fixed abutment on the first carriage and is adapted to clamp the belt run in question against the associated abutment when the piston is axially displaced and thus connect said carriage to the belt run in question travelling between the shoe and the abutment.
