Definitions

  • This invention relates to the delivery of slivers from textile machines into cans. Many attempts have been made to carry out such delivery so that the sliver is packed in a regular manner in the can, for if that is and the subsequent unfolding of the sliver, in order to carry out further operations upon it, is rendered diflicult. It is the principal object of the present invention to provide a mechanism for piling sliver into cans in a zigzag manner which would be relatively simple and more satisfactory than devices hitherto employed.
  • the sliver is delivered to a pair of rollers turning inwardly with respect to each other about their parallel axes substantially at right angles to the width of the sliver but at a linear speed somewhat less than that at which the sliver is supplied to the rollers.
  • the gap between the surfaces of the two rollers is rather less than the width of the sliver, and these surfaces engage the edges of the sliver, which is delivered to them near the rear end thereof somewhat obliquely.
  • the result of the difference of peripheral speeds is that the sliver is retarded and tends to bulge upwardly and,
  • the two rollers referred to are preferably placed justabovethe mouth of the can and may be associated with two or more additional rollers so that all the rollers act as presser rollers when the can becomes filled, to roll down the sliver and pack it into the can in a satisfactory manner.
  • the sliver may be supplied over an inclined delivery plate, and at the instant a full can is removed, it may be nipped and moment. not arranged, the can is not properly filled
  • Figure 1 is a side elevation of the delivery end of a carding engine to which the improved arrangement is applied. 7
  • Figure 2 is a sectional elevation at right angles to Figure 1 of the upper part of the mechanism taken on the line IIII in Figure 1.
  • the sliver is being fed into a can a carried on a platform 6, and a can 0 is empty and is waiting to take the place of the can a when the latter is full.
  • the platform I) and the cans are reciprocated by means of a crank (Z, connecting rod 6, and an upstandingbracket 7 carried by the platform 6 to which the connecting rod 6 is attached.
  • the carding engine is provided with the usual pair of delivery rollers g g and an inclined delivery plate It is mounted in front of the roller g in such a way that the sliver has to pass over the plate It on its way to the can a.
  • the cans a and 0 are substantially elliptical in plan, and as can be seen, are reciprocated in the direction of the major axes of the cans.
  • rollers and 70 are mounted between the lower end of the delivery plate It and the top of the can a there are mounted two rollers and 70 with their axes at right angles to the width of the sliver, and consequently at right angles to the major axis of the can a.
  • the rollers 10* are driven from a spindle I through bevel wheels 772 and m so as to turn inwardly as shown by the arrows in Figure 1.
  • the roller 70 turns clockwise and the roller 70 counter-clockwise, but at speeds such that the linear sped of the surfaces of the rollers is rather less than that of the delivery rollers 9 g of the .carding engine.
  • the width of the gap between therollers k and 10 as seenin Figure 1 is rather less than the width of the sliver shown diagrammatically at n.
  • the rollers 70 engage the edges of the sliver, which initially is fed to the rear ends thereof down the inclined plate h.
  • the effect of the retardation due to the slower peripheral speed of the rollers 70, 76 will be clear from Figure 2.
  • the line w indicates the form which the sliver first takes on entering these rollers. Owing to the retardation the sliver by degrees takes the form indicated by the lines in and a, bulging upwardly and forwardly and at the same time travelling forward between the rollers. lVhen it reaches the position indicated at 2, its weight causes it to collapse to the position shown by the dotted line y.
  • the sliver is folded back upon itself. That part of it which is adjacent the plate It presently assumes the position indicated at w so that the initial conditions are renewed and the same cycle of operations is repeated. Thus the sliver has imparted to it a more or less regular zig-zag form solely by reason of the retardation aforesaid.
  • the legs of the zig-zag tend to fall apart again owing to gravity.
  • the distance through which it falls is, however, so small that substantially no opening out of the zig-zags takes place, particularly as this form is rendered more or less permanent by the lateral pressure exerted by the rollers.
  • the folds lay themselves flat together as soon as they reach the bottom of the can or the fold previously laid.
  • the velocity ratio between the rollers g, and 7c, 79 can be varied within wide limits. depending on the character of the sliver. It may for example be 3:2. Owing to the reciprocation of the can the successive folds are drawn out sideways so that the whole width of the can is occupied.
  • a pair ofadditional rollers 0 0 is arranged above the can a, the rollers being parallel to the rollers m and 721 while the roller 0 is outside the roller m and is driven similarly to it and in the same clock-' wise direction, while the roller 0 is driven in the same direction as the roller lcflthat is in a counter-clockwise direction,
  • the four rollers, '0 7: 7m 0 act to roll down the sliver and press the same into the can so that as the can reciprocates below the rollers, the sliver is packed firmly into the can.
  • the effect when the cover p is lowered is to retain the sliver on the delivery plate h and only allow it to fall into the empty can 0 when the latter has fully arrived in its position to receive the sliver.
  • the cover 7) is then lifted and the can 0 continues to be filled as already described.
  • This gearing comprises bevel wheels s, a chain 6, and the bevel gearing m and m already referred to.
  • a mechanism for delivering sliver into cans comprising a pair of rollers arranged above the can with their axes at right angles to the width of the sliver, a driving mechanism connected to said rollers to rotate them in opposite directions so that their upper surfaces move inwardly, aud means for delivering sliver to the bite of said rollers near one end thereof at a speed greater than the peripheral speed of said rollers.
  • a mechanism for delivering sliver into cans comprising a pair of rollers arranged above the can with their axes at right angles to the width of the sliver, spaced apart with a. gap between them less than the width of the sliver and driven to rotate in opposite directions so that their upper surfaces move inwardly, and means for delivering sliver to the bite of said rollers near one end thereof at a speed greater than the peripheral speed of .said rollers.
  • a mechanism for delivering sliver into cans comprising a pair of rollers arranged above the can and frictionally engaging the edges of the sliver, means for rotating them to urge the sliverdownwardly, and means for delivering sliver to. the bite of said rollers near one end thereof in a direction inclined to the. vertical at a speed less than the peripheral speed of said rollers.
  • a mechanism for delivering sliver into cans comprising a pair of rollers arranged above the can and frictionally engaging the edges of the sliyer, means for rotating them to urge the sliver downwardly, a pair of sliver delivery rollers situated above said rollers at one. end thereof, engaging the faces of the sliver and means for rotating them at a peripheral speed greater than that of the rollers first mentioned.
  • a mechanism for delivering sliver into cans comprising a pair of rollers arranged above the can and frictionally engaging the edges of the sliver, means for rotating them to urge the sliver downwardly, a pair of sliver-delivery rollers situated above said rollers at one end thereof, engaging the faces of the sliver, means for rotating them at a peripheral speed greater than that of the rollers first mentioned, a support for the can, and means for reciprocating said can horizontally in a direction transverse to the axes of said rollers first mentioned.
