Definitions

  • the present invention relates to a device for depositing a sliver in a can, comprising a depositing head with take-off rollers for transporting the sliver into the can via a rotatable turntable arranged below the depositing head and with at least one sliver funnel arranged pivotably for the automatic separation of the sliver when the sliver is changed Jug.
  • the sliver delivered by the spinning preparation machine is taken over by a so-called sliver depository.
  • the sliver is guided via guide aids via a sliver funnel to a pair of calender rollers, which deposits the sliver into the cans that are waiting by means of a turntable.
  • the sliver is severed, with the full can being removed and an empty can being pushed in at the same time.
  • the delivery head of a can changer in which the sliver coming from a card is guided into a sliver funnel and fed into the rotating sliver channel of a turntable by means of calender rollers. Due to the rotary movement of the turntable in combination with the rotating can, the fiber sliver is deposited in the can in the form of a cycloid. To change the can, the sliver must be torn and inserted into the new can. For this purpose, the sliver is clamped inside the sliver funnel and at the same time the sliver funnel is removed from the calender rollers, whereby the sliver tears. Because the distance between the sliver funnel and the calender rolls is reduced again after the tear-off process, the calender rolls grasp the end of the torn sliver so that the can changer can continue to operate automatically.
  • the DE 102006012335 A1 describes the displaceable arrangement of the tape guide funnel from an operating to a waiting position.
  • the take-off roller can be pressed against the take-off roller by means of the pneumatic loading means in order to increase the pressure on the sliver depending on the quality of the fleece.
  • the take-off roller can also be moved away from the take-off roller by pivoting it about a pivot point by means of pneumatic loading means in order to create a gap.
  • a depositing head of a can changer in which a depositing tube is arranged at an angle (45 °) with calender rollers arranged at the end.
  • a first calender roll is driven by a friction wheel that is driven on a rotating head carrier.
  • a second calender roll is practically dragged along.
  • the calender rollers can be swiveled out of the longitudinal direction of the storage tube, but at the same time the necessary pressure for the friction wheel can also be generated. This is intended to facilitate a cleaning process.
  • the GB 883,306 discloses the pivotable or displaceable mounting of the sliver funnel, in which the sliver is still clamped by the take-off rollers during the can change.
  • the pivoting movement is carried out by a plunger which engages the flap in the area of the swivel joint.
  • the plunger can also be part of an armature of a motorized or magnetic actuation.
  • the disadvantage is that the funnel has to be opened manually by the operator in order to remove blockages or for cleaning work. Then the calender rolls can be opened separately with a lever. This is time-consuming and difficult to accomplish for the operator, especially with large cans in an unfavorable position at a height of about 1.60 to 1.80 m.
  • the object of the invention is to develop a device for cutting the sliver on a can changer.
  • the device should be designed to be structurally simple and user-friendly.
  • This task is based on a device for depositing a sliver in a can, having a depositing head with take-off rollers for transporting the sliver via a rotatable turntable arranged below the depositing head into the can and with at least one swiveling sliver funnel for the automatic separation of the sliver when changing the jug according to the preamble of claim 1 and solved with the respective characterizing features.
  • the invention includes the technical teaching that the device has means with which the distance between the take-off rollers can be increased and with which at least the sliver funnel can be moved away from the take-off rollers. This facilitates the maintenance process, since the storage head can be opened completely with just one actuation in order to carry out cleaning work.
  • the automatic separation of the sliver takes place by means of a cylinder which moves the sliver funnel away from the take-off rollers, while the fiber sliver is clamped by the take-off rollers.
  • the cylinder can be operated automatically via the control of the can body when changing cans, or it can act as a rigid component that swings the funnel with the sliver guide away from the take-off rollers.
  • the means have at least one swivel joint with which the cylinder and a take-off roller can be moved. Further mechanical components, with which both the take-off roller and the cylinder are movably attached, can be attached to the swivel joint.
  • the swivel joint is designed as a split swivel joint which is connected via an eccentrically arranged bolt.
  • This eccentrically arranged bolt creates space for the cylinder on the one hand, but also acts as a rotary engagement point for the mechanical displacement of the cylinder, whereby the sliver funnel with the pre-compressor is moved away from the take-off rollers.
  • the cylinder is connected to the eccentrically arranged bolt.
  • One draw-off roller is advantageously arranged in a stationary manner, while a second draw-off roller is arranged movably.
  • the movable arrangement takes place directly or indirectly rotatable on a frame.
  • the piston rod of the cylinder can advantageously be retracted under pressure by means of a 5/2-way valve.
  • the cylinder thus acts as a rigid component which, thanks to the eccentrically arranged bolt, enables the sliver funnel to pivot.
  • the piston rod of the cylinder can advantageously be moved into a pressureless central position by means of a 5/3-way valve, whereby the cylinder with the piston rod acts as a telescopic component. This allows the sliver funnel with the pre-funnel to be opened by hand.
  • Figure 1 shows a card A, from which a sliver B is guided to a depositing head 1 in a can changer C and deposited in a can D1, D2.
  • the can changer C is designed as a linear can changer in which the depositing head 1 is arranged to be linearly displaceable along a frame or a rack wall.
  • the can changer C can, however, also be designed as a rotary can changer, in which the cans D1, D2 are changed by means of a rotating device underneath the fixedly arranged depositing head 1.
  • the storage head 1 is arranged under a covering, which is not designated in detail, and is described in detail in the following figures.
  • Figure 2 shows the storage head 1 in an operational position. What is essential is the pre-funnel 16 with the sliver funnel 17 arranged below it (see Fig. 3 ) and the take-off rollers 20, 21.
  • a sliver is guided via guide rollers, for example from a carding machine, to the delivery head 1 of a can changer and there guided through the pre-funnel 16 with the sliver funnel 17 arranged below.
  • the take-off rollers 20, 21 ensure a constant transport of the sliver into the rotating cans arranged under the depositing head 1.
  • the fiber sliver can be deposited in the can in the form of a cycloid, there is a turntable (not shown) below the deposition head 1, on which a curved sliver channel is rotatably arranged.
  • the registration refers in full to the DE 3807239 .
  • the sliver can be clamped in the area of the sliver funnel 17 and torn apart by increasing the distance between the sliver funnel 17 and the take-off rollers 20, 21 ( Fig. 3 ) will.
  • the distance is increased by means of a cylinder 18 which, for example pneumatically driven, engages with its piston rod 19 on an engagement element 13 below a pivot point 12.
  • Sliver funnel 17 and pre-funnel 16 are arranged below a plate 10, which are reinforced on the underside by one or more angled reinforcement profiles 11 and are mounted pivotably about a pivot point 12.
  • the two reinforcement profiles 11 are arranged spaced apart in the region of one longitudinal side of the plate 10.
  • a rod which is designed as a pivot point 12, penetrates both reinforcement profiles 11 and is attached to a frame 2 of the storage head 1.
  • a rod or a tube is also formed as an engagement element 13, which likewise penetrates both reinforcement profiles 11.
  • the piston rod 19 of the cylinder 18 engages the engagement element 13 and pivots the sliver funnel 17 in a circular arc from the take-off rollers 20, 21 away.
  • a first pre-compression ring 15 with a second pre-compression ring 14 can be arranged, with which a voluminous band is pre-compressed.
  • the sliver can be clamped within the sliver funnel 17 by a clamping element, not shown, which is pneumatically actuated, for example, on or in a wall of the sliver funnel 17 and clamps the sliver.
  • a clamping element not shown
  • the inner diameter of the pre-funnel 16 and the sliver funnel 17 can be adjusted so closely to the dimensions of the sliver to be processed that a jerky movement of the pre-funnel 16 and sliver funnel 17 away from the take-off rollers 20, 21 is sufficient to tear the fiber sliver.
  • the representation of the Figure 4 shows a top view of the storage head 1, which is shown with the pre-funnel 16 and the sliver funnel 17 open.
  • the cylinder 18 with the sliver funnel 17 is swung up by means of the piston rod 19, as a result of which the sliver funnel 17 is removed from the take-off rollers 20, 21 holding the fiber sliver and thus the sliver tears off. This is done so far automatically by the control, which supplies the cylinder 18 with compressed air. In order to remove the wound fiber tape from the take-off rollers 20, 21, these must be moved apart.
  • the take-off rollers 20, 21 are mounted with their gear bearings 34, 35 in a frame 33 and opposite the take-off rollers 20, 21 have drive pins 23, 24 which are driven by a motor via a belt (not shown). At least one take-off roller 20 or 21 is arranged in a stationary manner with the gear mounting 34 or 35 and the drive pin 23 or 24, the second take-off roller 20 or 21 being adjustable. The adjustability for cleaning and maintenance takes place in this exemplary embodiment, in which the take-off roller 21 with the gear bearing 35 and the drive pin 24 is arranged in a stationary manner on the frame 33.
  • the second adjustable take-off roller 20 is pivotably mounted with the gear bearing 34 and the drive pin 23 in the frame 33 in a pivot bearing 25 such that the distance between the take-off rollers 20, 21 is adjustable.
  • the gearbox bearing 34 is connected with a rod 32 and an articulated connection 31 with a swivel joint 27a, 27b.
  • the invention provides a lever 26 with which the sliver funnel 17 can be raised manually and at the same time the take-off rollers 20, 21 can be moved apart.
  • the lever 26 cooperates with a swivel joint 27a and 27b which is divided in the axial longitudinal extension and which is mounted in a stationary bearing 30.
  • the swivel joint 27a, 27b has a subdivision in its longitudinal extension which is formed by two rotary plates 28a and 28b with a bolt 29 which is arranged eccentrically to the rotary joint 27a, 27b and connects the rotary plates 28a, 28b.
  • On the bolt 29 is the Cylinder 18 attached, which is supported on this by means of compressed air during automatic actuation.
  • the lever 26 When using a 5/2-way valve for the cylinder 18, the lever 26 is operated manually for the maintenance process. As a result, the sliver funnel 17 pivots away from the take-off rollers 20, 21. The take-off rollers 20, 21 move or pivot apart and can be cleaned. The cylinder piston is retracted because it is pressurized by the 5/2-way valve and acts as a rigid component that enables the sliver funnel to pivot through the eccentrically arranged bolt.
