Definitions

  • This invention concerns the sector of circular knitting machines of the type with a rotating dial, bearing components set out in a radial, horizontal manner, which make stitches together with the vertical needles of the cylinders of these machines.
  • the main purpose of this invention therefore is to equip circular machines, especially knitting ones, with a dial for the radial-horizontal components that can be raised or lowered according to requirement and depending on the functions and working phases in progress.
  • This purpose is achieved with a plate located co-axially above the cylinder of a knitting machine, guided vertically and commanded by a servo-mechanism of any kind for its movements and height positioning above the cylinder.
  • the dial can be raised to assume various positions with great precision, even when the machine is operating, depending on the operating requirements in the construction of the desired knitting and/or cylinder access and/or the other neighbouring components for inspections and various controls.
  • the dial would continue to be coupled with the respective command components and to rotate like the cylinder, a condition which can represent a danger to the safety of the operator who has to perform work and which can obstacle the effective free access to the inside of the cylinder from its top and to the surrounding components.
  • Another purpose of this invention therefore is to create the conditions to stop the dial from rotating when raised to a certain height above the cylinder, even when this continues to rotate.
  • a still further purpose of this invention is to associate devices to stop its rotation to the dial when in the raised position to permit access for work from above, inside the cylinder without useless risks to the operator: in this way, the known technical problems and the safety issues complained of above are excluded.
  • a further purpose of this invention is to stop the dial from rotating when in the raised, idle position, but also to keep its correct position in relation to the cylinder when lowered and made to operate again.
  • the drawings show a cylinder (11) with needles (12) vertically arranged of a circular machine and a rotating dial (13) fitted above the cylinder, bearing horizontal components (14) such as needles, hooks or other parts, to make the stitch in combination with the vertical needles on the cylinder.
  • the dial (13) When operational, the dial (13) rotates perfectly synchronous with the cylinder (11). To rotate, the dial can be driven by its own motor device or more commonly by gear or similar transmission derived from that rotating the cylinder.
  • a toothed drive wheel (15) on a motor shaft (16) and a toothed driven wheel (17) on a shaft (18) supporting the dial is shown of this type of transmission. Toothed wheels (15) and (17) normally engage when the dial is in the operating position.
  • the dial (13) can be adjusted in height between a lowered, operating position, in which the wheel is driven by the transmission 15, 17 and a raised, idle position, in which it is raised. To this purpose it is connected to and commanded by a servo-mechanism 19.
  • This may be mechanical, electrical, electro-mechanical, pneumatic and can anyway be programmed and managed through the electronic apparatus circular machines are usually equipped with for controlling their operation and the stitch construction phases.
  • the dial can be positioned in height above the cylinder, even when this is rotating, according to the work program or for maintenance operations and for all work at the top and inside the cylinder.
  • the dial is equipped with at least one stopping device (20) interfering directly or indirectly with the dial to block its rotation, when in the raised or in other words idle position.
  • the stopping device (20) is comprised of a fixed catch (21) located above the drive wheel (15) that intercepts the driven wheel (17).
  • the dial is raised until the driven wheel (17) disengages from the drive wheel (15) (dotted line in Fig. 1) and at that level, the fixed catch (21) intercepts the driven wheel (17) thus automatically arresting the rotation of the dial, as soon as it finds itself raised to the idle position, that permits access to the cylinder from above.
  • the stopping mechanism (20) could be configured or arranged in any other way, as long as it is suitable for stopping the rotation of the dial when in the raised position.
  • This device can be stationary or move between an active and inactive position, commanded by any mechanical, electrical, electro-mechanical or pneumatic means. It may be oriented vertically or transversely to the dial, to the driven wheel, the dial shaft or to any other element onboard the dial, always with the purpose of being able to stop the same from rotating when raised and disengaged from its drive transmission. With the adoption of a moving stopping device, the blocking/releasing of the dial rotation can be controlled according to need and managed by the machine's electronics.
