SU130809A1 - Adaptation to the carding machine to automatically disable the tape length counter when it breaks on the duplicated board - Google Patents

Description

Known adaptations to a carding machine for automatically disconnecting a tape length counter when it breaks on a duplicated board contain rotary styli, kinematically connected with a two-arm lever that affects the length counter drive mechanism, and a tray for transferring the tape from one pelvis to another.

The described device differs from the known ones in that each probe interacting with the tape entering the slot of the duplicated board is made in the form of a plate fixed on a rotary sleeve with a protrusion on one side and mounted on a fixed hollow roller with several transverse slots, located opposite the protrusions of the rotary sleeves, and inside of this roller is a rotary bar, which is equipped with several axles, interacting with the protrusions of the rotary sleeves, and one tooth. The latter interacts with the end of the movable spring-loaded rod, the second end of which interacts with the free end of the two-arm swinging arm connected with the drive mechanism of the tape length counter and the turning tray for transferring the tape into another basin.

To enable the mite length counter, a gear coupling was used, one half of which is rigidly connected to the KOvieca worm gear drive hub, and the second half of it is movably mounted on the worm gear shaft and connected to the end of the two upper arm by means of a fork.

These distinctive features of the device simplify its design.

FIG. 1 shows the device, top view; in fig. 2 is the same side view; in fig. 3 probe; in fig. 4-bar; in fig. 5-interaction-tape and probe (in section).

No 130809- 2 Under the duplicate board / against each of its slots 2 a rotary probe 3 is mounted, made in the form of a plate - probe, which is pressed from below to the duplicated board 1, passing under it tape 4. Each plate-probe 3 is fixed on the rotary sleeve 5, having 6 on one end. The rotary bushings 5 are mounted on a fixed hollow roller 7 with transverse slots located opposite the projections of 6 rotary bushings 5. Inside the fixed hollow roller 7 passes a rotating bar 8, Which is provided with several pins 9. Each of the tip c passes through the notch of the stationary hollow roller 7 "interacts with the protrusion 6 of the rotary sleeve 5. The bar 8 is provided at one end with a tooth 10 interacting with the end of the shank 11. The latter has a spring 12 with which the shank rests with its teeth into the stationary void 13 protecting it from longitudinal movement. This shtanga // interacts with the longitudinal movement of slide 14 with one end of the two shoulders lever 15 turning about axis 16. The other end of lever 15 carries a fork 17, which interacts. one half of the gear coupling 18. The other side of the coupling 18 is fastened to the bushing of the worm gear 19 to drive the tape length counter and is connected to the rotary chute 20 for transferring the tape from one pelvis to another.

When the duplicated board 1 is broken by one of the passing ribbons 4, the probe 3, which is not held by the tape, rotates together with the sleeve 5 under the action of its own weight on the stationary hollow roller 7. At this time, the protrusion 6 presses the sleeve 5 and rotates the rod 8. When the latter is rotated, the tooth 10 presses on the end of the rod //, which with the teeth slips off the stops 13 and under the action of the spring 12 moves to the right (Fig. 4) along its axis. At the same time, the right end of the lever 15, sliding along the slide M, is lowered down by the action of its own weight, and the left end together with the fork 17 rises up, uncouples the clutch 18 and disconnects the tape length counter. After refilling the broken ribbon, the rod 11 is pulled off manually, with the device being brought to a working condition.

Claims (2)

1. An accessory for the carding unit to automatically turn off the tape length counter when it breaks on a duplicated board, including turning probes kinematically associated with a double-arm lever acting on the drive mechanism of the length counter, and a tray for transferring the tape to another basin, distinguished by that, in order to simplify the design, each probe interacting with the tape entering the slot of the duplicate board is made in the form of a plate fixed to. a rotary sleeve with a protrusion at one end and mounted on a stationary hollow roller with several transverse slots opposite the projections of the rotary bushings, and inside the hollow roller there is a rotary rod equipped with several teeth of the rotary bushings and one tooth interacting with the end movable spring loaded bar, the second end of which interacts with the free end of the two-arm swivel lever associated with the mechanisms for driving the tape length counter and along door tray to transfer the tape to another basin. 2. Device according to claim 1, characterized in that a tape-type coupling is used to turn on the tape length counter, one half of which is made integral with the bushing of the counter drive worm wheel, and the second half of it is movably mounted on the worm pinion shaft and connected by means of a fork with the end of the two shoulders swivel arm.
