Description

one

The invention can be used in STB type weaving machines.

A device for tracking times to a weaving machine is known, comprising a clutch mounted on a machine transverse shaft, a clutch disengaging mechanism and an electric motor connected kinematically to a shedding mechanism.

A disadvantage of the known device is the presence of manual operations when disengaging a clutch.

The aim of the invention is to increase comfort.

For this, the electric motor is kinematically associated with the machine weft fork mechanism and the clutch disengagement mechanism.

Figure 1 shows the kinematic scheme of the device proposed; Fig. 2 is the same, is a top view without a clutch and its disconnection assembly.

The device contains an electric motor I and mechanical transmission systems mounted in the gearbox housing 2. The gear housing housing is attached to the frame of the weaving machine 4 with the help of the bracket 3; gear sectors 7 and 8, respectively, are applied to the vertical shaft 9 in the bevel 5 and cylindrical gear 6 The assembly 10 is located, by means of which the clutch -ii of the shedding mechanism with the drive of the weaving machine is disengaged.

The electric motor I is kinematically connected with eccentrics -12 of the shedding mechanism by means of a screw pair 13, 14 mounted on the drive shaft 15; chain 6 and sprocket d7 seated on the keyed shaft 8; chain transmission -19 and spur gear 20.

When a weft yarn is broken, the fork turns on the device electric motor at the same time as the machine drive is turned off. The latter, turning the screw to -13 and the black wheel -14, drives the shaft -15 into rotation. Together with valou 15, the toothed sectors 7 and 8, which are rigidly mounted on it, are mounted on the shaft 15 so that after switching on the electric motor I, the conical sector rotates the bevel wheel 5 by a certain angle; and with it the vertical shaft 9: clutch clutch 10, clutch assembly 10. This accomplishes disengagement of the diaphragm 8 from the drive of the weaving machine. Then the bevel wheel 5 stands, and the cylindrical toothed sector 8 is put into operation, which through the gear wheel 6, the sprockets 1 (one of which is rigidly mounted on the -18 shaft) and the chain-16 rotates the shaft 360, and with it eccentrics -12 of the shedding mechanism (by means of a chain drive 19 and a gear-type cylindrical gear 20-.), which corresponds to finding 0, waiting for the previous pharynx, in which there is a dangling thread. The gear sectors 7 and 8, having completed a complete revolution with the shaft 5, are stopped, ready to repeat the work done after switching on the electric motor -1.

A further rotation by inertia is prevented by a worm pair (a worm-13 and a worm wheel 14) with self-braking properties. The motor I is stopped after a complete revolution of the shaft 15 by a cam 2i acting on the limit switch 22.

Characteristic for the mechanical transmission of the device proposed is that in the conical and

cylindrical gears used gear sectors, made in such a way that during one complete rotation of the shaft, the bevel gear sector 7 rotates the bevel gear 5, and with it the vertical shaft of the disengagement mechanism 10 of the clutch II at the desired angle (approximately 60-70 ° ), which corresponds to the disengagement of the clutch -I, after which the taper pair stands, and the cylindrical gear sector 8 comes into operation, which, turning the gear wheel 6 with the asterisk -17 fixed with it through the chain 6, rotates the spindle shaft 18, and the last eccentrics12 are zoobazovator-. of the mechanism at 860,

During the periods when the shed-forming eccentrics work from the main electric motor, there is no connection with the drive of the searcher. This is provided through the cylindrical gear sector 8., which at this time is not engaged with the gear wheel 6, rotated by the spindle shaft 18 through a chain transmission: sprocket i7 and chain 16.

When found in this way, it remains only to remove from the pharynx the ends of the broken gommon and turn on the walls in the usual way.

SUBJECT MATTERS

A device for locating a weaving machine comprising a clutch mounted on the machine’s transverse shaft, a clutch disabling mechanism and an electric motor are kinematically associated with a shedding mechanism, characterized in that, in order to enhance machine service convenience, the electric motor is kinematically connected with the weft mechanism machine forks and with a clutch release mechanism.
