    • D01H9/182—Overhead conveying devices

Definitions

  • the invention relates to a device for conveying full and empty roving bobbins between the creel of a textile machine, in particular a ring spinning machine, and a transfer station, with a circulating monorail having rails running parallel to the creel, on which a transport unit can be moved.
  • a monorail around the ring spinning machine can be provided to convey full and empty roving bobbins.
  • 1 shows an existing system with a closed or endless rail, on which transport carriages or trolleys, which lead coils from a transfer station parallel to the gate, can be moved by means of brackets having rollers. An operator transfers the empty spools from the gate to the trolley and full spools from the trolley to the gate. The trolleys are moved along the rail by a friction wheel drive.
  • DE 32 40 822 shows a chain which runs around the ring spinning machine and consists of elongated links which are articulated at the ends and on which hanging pins for coils are arranged, the chain hanging on a sliding monorail. Due to the construction of both devices, the overhead conveyor takes up a lot of space on the narrow sides of the ring spinning machine. This disadvantage is particularly serious if a winding machine is arranged in a link with the ring spinning machine on a narrow side. But the passage on the other narrow side of the ring spinning machine is also narrowed due to the space requirements.
  • a particularly assembly and repair-friendly, relevant device is made possible by the teaching of claim 4, because the drivers can be quickly replaced if necessary. Fixing the drivers in the vertical direction prevents them from falling.
  • Claim 5 provides a teaching, according to which the tape can be arranged more gently, in such a way that wear of the rail through the tape is made impossible.
  • a ring spinning machine 4 with 4-row attachment according to FIG. 1 has two rows of work coils on both sides of the machine center plane 5, which are indicated by the gate coils 6 and 7.
  • Reserve roving bobbins 10 can be moved longitudinally on a monorail 9 via a bar chain or a carriage, the reserve roving bobbins 10 being approximately at the same height as the creel bobbins 6 and 7.
  • the changing of the empty gate coils 6 and 7 and the reserve coils 10 is done by hand switching.
  • a friction wheel drive 11 transports the trolley or trolleys or a drive sets the chain in motion, as a result of which the empty spools reach a transfer station 14.
  • the device according to FIG. 2 works with the aid of an endless, upstanding or vertically aligned or standing steel strip 24, which has four deflection rollers 25, 26, 27, 28 is tensioned and is arranged in a rail 29 shown only on one machine longitudinal side.
  • the monorail and the steel belt 24 can run around the entire ring spinning machine 4 (reference number 9.2) or, according to an advantageous embodiment, only around the drive head 16 and the gate 30 (reference number 9.1).
  • the monorail 9.1 leads through a passage between the end head 18 and the gate 30, this passage only having to be so wide that a full spool does not touch.
  • On the narrow sides of the monorail 9.1 there are also preferably rails 31 (only shown on the right in FIG. 2) which are identical to the rails 29.
  • the slots 37 have, for example, a width of 1-2 mm and can preferably be punched close to one another, for example 2-3 mm in the band, so that the drivers 35 can be placed or adjusted practically as desired.
  • a preferred placement of the drivers 35 is the spacing between the gate coils 6 and 7 in the gate 30.
  • an annular groove is provided for the passage of the tabs 36.
  • a deflection roller 27 is driven directly by a motor 40, the position of which is shown purely schematically, as a result of which the drivers 35 and the steel strip 24 have Transport unit is moved. If this friction drive proves to be insufficient, a drive belt or belt 41 can be tensioned from the deflection roller 27 to the deflection roller 28, so that the deflection roller 28 is driven indirectly by the motor 40.
  • a hinge pin 42 for a reserve roving bobbin 10 is preferably attached below the driver 35, for example by a snap connection.
  • the hanging pin 42 can of course also be arranged on the side of the driver 35.
  • the rails 29, 31 are attached to the structure of the gate 30.
  • One or more drivers 35 or one or more points on the steel strip 24 can be responsive to a stable or fixed sensor 43. This makes it possible to use keyboard 17 to determine a specific time duration setpoint to motor 40. In FIG. 4, for example, the sensor 43 is directed at the connection point between the hanging pin 42 and the driver 35.
  • FIG. 3 shows an arrangement in which a rotating steel band 24.1 and a suspension track (not shown) following this band are assigned to a machine longitudinal side.
  • the steel band is shown alone, in the lower half it is shown how the steel band 24.1 is stretched over deflection rollers 46, 47, 48, 49.
  • Two parallel band strands 52, 53 thus run along a gate side, so that the reserve coil capacity is doubled over this gate length. It is thus possible to replace all gate coils 6, 7 on one side of the gate with reserve prewarning coils 10 on run 52 and reserve prewarning spools 10.1 on run 53 without the steel strip 24.1 having to be moved.
  • the belt strands 52, 53 extend to the end head 18 and on the other side make a kink around the drive head 16, where the transfer station 14 is located.
  • the belt or the overhead conveyor on the other side of the machine is arranged in mirror image.
  • the deflection roller 48 is driven directly, but it is possible to drive both belts 24.1 at the same time. This can be done, for example, by a Drive belt 41 take place.
  • the deflection roller 49 is the only roller that also comes into contact with the driver 35. In this case, it is necessary to make these drivers 35 somewhat thicker. It is advantageous to adapt the outer surface of the driver to the roller surface.
  • the steel strip 24, 24.1 can also be assembled from partial strip sections by means of connecting sleeves 55 (FIG. 5). This makes it possible to realize all the desired strip lengths with a small number of these sub-strip sections. Subband sections can also be replaced if damaged. For further details, reference is made to the patent application EP 89 117 489.8.
