Definitions

  • the invention relates to a device for cutting a sliver, as described in the preamble of the first claim and can be found in US Pat. No. 3605198.
  • a device for automatically changing cans in which a sliver is held by a pivotable double arm and separated by means of a pivoting movement of two levers in a direction transverse to the sliver.
  • Another US Pat. No. 3354513 shows a pair of scissors which can be actuated automatically by a power means and which separates a band sagging between the band channel outlet and the displaced full can.
  • a third US patent number 3381342 finally shows and describes a sliver separating device in which, after the can has been changed, the sliver is gripped by a pneumatically displaceable gripper and brought against a separating means which can be moved in the opposite direction.
  • the release agent is actuated by the gripper.
  • the invention has for its object to remedy these disadvantages and to propose a simple tape cutting device which can be operated simultaneously with the can change. This object is achieved by the invention set out in the claims.
  • FIG. 1 and 3 each show an elevation of part of a can changing device with a can filling station and a can extending device and with a device according to the invention, shown semi-schematically,
  • Figures 2 and 4 each have a plan view of the device of Fig. 1. 3, shown semi-schematically.
  • a funnel wheel 3 (indicated by dotted lines in FIGS. 1 and 2) is rotatably mounted in the head part 2.
  • the funnel wheel serves to receive a sliver channel 4 (indicated by dashed lines), which has a sliver outlet opening 5.
  • FIG. 1 On the bottom part 1 there is a can 6 to be filled in FIG. 1 (shown with dash-dotted lines).
  • a can extending device 7 consists of a chassis 8, an arm 9 pivotally arranged thereon and a can carrier 10 pivotally arranged thereon.
  • the chassis 8 is movably supported on rails 14 and 15 by means of rollers 11, 12 and 13 arranged thereon.
  • the rails 14 and 15 are part of the can filling station.
  • the arm 9 or the driver 10 is pivoted by means of a double-acting pneumatic cylinder 16, which is pivotally connected on the one hand to the driver 10 and on the other hand to the arm 9 via a spring member 17.
  • the spring member 17 comprises a helical spring 18 which can be subjected to tensile and compressive stress and which is guided in a bush 19 against lateral swerving in such a way that the spring windings are slidably guided on the inner wall of the bush 19.
  • the sleeve 19 is connected to a piston rod of the cylinder 16.
  • One end of the spring 18 is fixed to the sleeve base 21 and the other end is articulated to the arm 9 by means of articulated bolts 22.
  • the arm 9 serves to receive a belt scraper 23, which consists of a holder 24 and a hard lip 25 made of plastic, for. B. polyurethane.
  • a tab 26 provided on the holder 24, together with a hinge pin 27, serves for the articulated connection of the band scraper 23 with the arm 9. This pivotability is only necessary in order for the band scraper 23 to be in precise contact with the underside 29 of the head part 2, which is flush with the underside 28 of the funnel wheel enable.
  • Arm 9 is such that the position of the belt scraper 23, relative to the arm 9, does not change when pivoting from the working position shown in FIGS. 1 and 2 into a substantially vertical starting position (not shown).
  • the chassis 8 of the can extending device in the direction of arrow A ver pushed so that the driver 10 comes to rest against the full can 6 and moves it away from the can filling station in the aforementioned arrow direction A.
  • the wiping lip 25 detects the fiber sliver which has meanwhile stopped at the exit opening 5 of the sliver channel 4 and tears the fiber sliver by means of this wiping movement within a feed length B which corresponds to at least twice the length of the longest fiber contained in the sliver.
  • the minimum can extension distance must therefore be selected such that this condition is met.
  • the pneumatic cylinder 16 is actuated again, so that the driver 10 and the arm 9 pivot back into the starting position. Thereupon the can extending device moves back into its starting position shown in FIGS. 1 and 2. In the meantime, an empty jug was moved from either direction C or direction D to the jug filling position. The can filling process can then be started again.
  • the cans extend and thus also the strip cutting is carried out not with a straight movement but with a circular movement.
  • the arm 9 and the can driver 10 are pivotally attached to a rotary column 30.
  • the rotating column 30 is rotatably supported at the upper end in a bearing element 31 fastened to the head part 2 and the lower end in a bearing element 32 belonging to the bottom part 1.
  • the arm 9 When the can is extended, the arm 9 must be pivoted to the minimum that the distance B shown in FIG. corresponds to twice the length of the longest fiber contained in the ribbon.
  • the stopping of the exit opening 5 is not tied to a position within the circular movement of the opening, provided that. that the condition relating to route B is met.
  • the can extenders are each moved by a drive with appropriate control (neither shown), which are not part of this invention.
