Definitions

  • the invention relates to a take-off device for flat knitting machines, with a goods take-up roller divided into several coaxial partial rollers, in which each partial roller can be driven separately via an adjustable coupling.
  • a trigger device of the type mentioned above has been proposed in DE-PS 32 17 395.
  • the invention has for its object to provide a trigger device so that a continuous adjustment of the clutch of the individual sub-rollers can be done remotely and the clutch ensures a constant effect in each setting.
  • the object is achieved with a trigger device of the type mentioned in the invention in that the partial rollers are freely rotatably mounted on a common concentric driven shaft and their coupling to the shaft takes place in each case via an electromagnetic clutch with individually variable excitation.
  • the electromagnetic clutch allows the clutch to be adjusted remotely by simply changing the current supplied as a function of any control or regulating device which is not the subject of the present invention.
  • the entire trigger device can be formed on the concentric common drive shaft in a space-saving and robust manner in various ways and from rotationally symmetrical parts that can be produced to exact dimensions.
  • a stationary web which carries power supply lines, can dip into a circumferential gap between adjacent partial rolls, which web can also serve to support parts of the electromagnetic clutch that are held in a rotationally fixed manner.
  • the magnetic coupling permits precise adjustment of the driving torque as a function of the excitation coil of the electromagnet supplied current, in contrast to a more unstable electromotive rotary field coupling, as is known from EP-OS 261 049.
  • the design of the electromagnetic clutch of the trigger device can be different in adaptation to the required torque values and / or spatial conditions and can be designed according to the features listed in the subclaims.
  • FIG. 1 shows a take-off roller 10 from the take-off device for a flat knitting machine, which is divided into a plurality of identical coaxial partial rollers 11, which are arranged next to one another on a concentric drive shaft 13 to form peripheral gaps 12.
  • a web 14 projects into each of the circumferential gaps 12 between the individual partial rollers 11, and all webs 14 are fastened with one end region to a common support rod 15 which runs parallel and at a distance from the goods take-off roller 10.
  • the partial rollers 11 of the goods take-off roller 10 cooperate with a counter-pressure roller 17, and the knitted web 16 or several separate knitted webs 16 formed on the flat knitting machine are over one part of the circumference of one or more several partial rollers 11 and passed between these partial rollers 11 and the counter-pressure roller 17.
  • 3 to 6 each show an axial longitudinal section through two adjacent partial rollers 11, but with four differently designed electromagnetic clutches arranged within the partial rollers, with which one adjustable driving coupling of the partial rollers 11 with the central and common drive shaft 13 can be effected.
  • a clutch disc 20 is fastened on the common drive shaft 13 in the region of each of the partial rollers 11 arranged concentrically to the drive shaft 13, which is indicated by a fastening pin 21 anchored in the drive shaft 13.
  • an annular body 22 is supported, which carries an electromagnetic excitation winding 23.
  • the annular body 22 is connected to the web 14 which is immersed through the peripheral gap 12 between the two partial rollers 11 and is thereby held stationary. Power is also supplied to the electromagnetic excitation winding 23 via the web 14 in a manner not shown in detail.
  • a concentric annular groove 24 is formed, into which an annular magnet armature 25 projects, which with a flange part 25.1 by means of screws 26 on radial webs 27 of the partial roller 11, which is freely rotatably mounted on the drive shaft 13 by means of a hub 28 is attached.
  • the drive shaft 13 of the take-off device is driven by a motor, not shown, at a speed which is at least so large that it can impart a maximum take-off speed to the partial rollers 11 for an orderly take-off of goods.
  • the electromagnetic winding 23 is de-energized, the partial roller 11 can be on the drive shaft 13 rotate freely and does not cause any pulling force on a knitted web 16 guided over it.
  • the electromagnet is energized by supplying current to the excitation winding 23, the magnet armature 25, which is firmly connected to the partial roller 11, is electromagnetically coupled to the clutch disc 20, which is firmly connected to the drive shaft 13, and thus A torque is transmitted to the partial roller 11 from the common drive shaft 13, which torque depends on the strength of the current conducted into the excitation winding 23.
  • the partial roller 11 begins to slip relative to the clutch disc 20. Since the electromagnetic clutch works purely non-positively, the electromagnetic clutch is practically wear-free. The torque occurring on the ring body 22 during the electromagnetic coupling is received by the web 14 and transmitted to the support rod 15.
  • the electromagnetic winding (not shown) is housed within the clutch disc 20 'which is firmly connected to the drive shaft 13'.
  • the power supply takes place via two on the circumference of the clutch disc 20 'formed conductor rings 29 which interact with arranged on a stationary and connected to the web 14 ring 30, which is also a protective ring against dusting of the conductor rings 29, sliding contacts.
  • the construction of the electromagnetic clutch is the same, and the same parts are provided with the same reference numerals as in Fig. 3.
  • the electromagnetic winding is again housed within the clutch disc 20 'fixedly connected to the drive shaft 13, which, as in the embodiment of FIG. 4, is supplied with current via a slip ring connection.
  • the magnet armature here consists of an annular disk 31 which can be tightened against an end face 20.2 of the clutch disk 20 'and can be designed as a friction disk ring or can be provided with a friction lining.
  • Axial parallel driving pins 32 are anchored in the annular disk-shaped magnet armature 31, which protrude into suitable recesses in the radial webs 27 of the partial roller 11 and thus create a rotationally fixed connection of the magnetic armature 31 with the partial roller 11, but allow the magnetic armature 31 to make an adjustment movement in the axial direction.
  • driving pins 32 ' are anchored in the radial webs 27' in kinematic reversal, which protrude into suitable through-bores in the annular disk-shaped armature 31 and on which the annular disk 31 can perform an axial movement.
  • FIG. 6 shows an embodiment of an electromagnetic clutch for the transmission of larger torques.
  • the electromagnetic winding is accommodated in a similar manner to the exemplary embodiment according to FIG. 3 in an annular body 22 which is held stationary by the web 14 and which has a sliding fit on the Socket part 20.1 of the clutch disc 20 fixedly connected to the common drive shaft 13 is arranged.
  • the magnet armature has the shape of a brake ring 33, which is freely rotatable and axially movable on the socket part 20.1 of the brake disc 20 and bears against an end face of the ring body 22 carrying the electromagnetic winding.
  • the magnetic armature designed as a brake ring 33 also has a ring gear 34, which lies at the same axial height as an inner ring gear 35 of the partial roller 11.
  • at least one pinion 36 is freely rotatably mounted on an axle pin 37, which simultaneously engages with the two sprockets 34 and 35.
  • the at least one pinion 36 rolls on the internal ring gear 35 of the partial roller 11 and thereby sets the electromagnetic armature, designed as a brake ring 33, in rotation via its ring gear 34.
  • the magnet armature designed as a brake ring 33 is pulled against the annular body 22, which is held stationary and expediently provided with a friction lining on its end face 22.1, and is braked to a greater or lesser extent.
  • the stronger the braking effect the stronger the pinion 36 is supported on the brake ring 33 and the stronger the torque is transmitted from the drive shaft 13 to the partial roller 11.
  • the stationary ring body 32 is supported via the web 14 in the manner already mentioned.
  • a pinion gear could also be arranged between the two ring gears 34 and 35 for torque reduction.
