SU124852A2 - Ribbon number controller for carding and belt machines - Google Patents

Description

BASIC Auth. St. jNs 96907 a tape number regulator for carding and ribbon machines was described, characterized in that an additional pair was installed at the main outlet pair of rollers, having an adjustable speed through the variator, and a sensor consisting of a hollow funnel that communicates; through an air duct with a source of compressed air and a pneumatic control mechanism acting on the speed variator.

The described controller is a further improvement of this, as it simplifies the design and increases the reliability of its operation.

A characteristic of the regulator is that the sensor of the regulator - a hollow funnel is connected, in addition to a source of compressed air, to a multi-chamber membrane servo motor, the stem of which is connected to the disks interacting with the membranes on the one hand, and on the other hand a double-shouldered lever carrying a conversion fork, with a spring-loaded roller of a disk variator of speed of an additional wire pair. In another embodiment, the lower end of the servomotor rod is connected through a full-arm lever with a conversion fork of the conoidal variator speed belt of the additional outlet pair.

FIG. 1 depicts a regulator with a speed variator; in fig. 2 - part of the regulator with a conoidal variable speed; in fig. 3 - funnel.

The tape number regulator is a single-zone stretch 124852

A device installed near the main exhaust cushion of the rollers and consisting of a power supply shaft of the valix / and exhaust roller 2.

The feed pair of rollers receives the thrust from the shaft 3 through gears 4, 5 and 6 and has a linear speed exceeding the speed of the main exhaust pair of rollers. The ejection pair of roller 2 receives rotation from the shaft 5 through alternating 1, the roller 7 along the axis, the interaction with the friction disk 8. implanted on the axis 9 of the draw roller, and has a variable speed depending on the position of the roller 7 relative to the center of the disk 8. Roller 7 equipped with a spring 10, squeezing the roller downwards, and the disk 6 - with a spring 11, pressing Dpsk to the roller. In front of the supply pair / install the regulator sensor is a funnel 12, which simultaneously serves to seal the tape and from the bottom of the upper 13 and lower 14 parts with openings for the tape strap 15. The inner CAVITY of the funnel is connected by a tube 16 to the main line 17 for compressed air through the nozzle 18, as well as with a tube 19 with a multi-chamber membrane servo mover 20. Rod 21; Ervomoto) and connected with discs 22 installed in the chambers of the latter, intersection; modulated with elastic membranes 23. The bottom end of the brush 21 shchar nirnno connected with the lever 24 carrying the conversion plug 25 for the roller 7.

Regulation of the tape number is produced by changing the size of its stretch between the supply Y and the exhaust 2 pairs of rollers due to the change in the speed of the exhaust pair 2. When an underestimated number passes through the funnel 12 of the lower number, the outflow of air entering the internal funnel of the funnel through the gaps between the military holes tape 5 and the openings of the upper 13 and lower 14 funnel parts are reduced. As a consequence, the air pressure in the chambers of the servomotor 20 increases. The elastic membranes 23 press down the disks 22, and the wiper 21 goes down and rotates the lever 24, the plug 25 of which moves the rotating roller 7 up closer to the center of the disk 8. The latter starts to rotate faster and increases the speed of the exhaust pair of rollers 2. The ribbon is extended and the number of the belt increases. In the case of a higher ribbon number passing through the funnel 12, the outflow of air from the internal cavity of the funnel to the atmosphere increases, the air pressure in the chambers of the servomotor 20 decreases, and the spring 10 does not lower the rotating roller 7; the speed of the disk 8 and the exhaust pair of rollers 2 decreases; tape stretching is reduced, and the tape number is lowered.

In another embodiment, the lower end of the H1 current 21 of the servomotor 20 pivots) is connected to the lever 26, a non-flexible convertible plug 27 acting on the belt 28. The belt connects the lower conoid 29 to the upper conoid 30. The lower conoid 29 receives constant rotation from the shaft 3 through a pinion. 31 and transmits rotation through the belt 28 to the upper conoid 30, which, with the nose of the gears 32, rotates the exhaust pair of rollers 2. The rest of the adjustment device remains unchanged.

Depending on the number of the tape passing through the funnel 12, the air pressure in the chambers of the servomotor 20 varies. The rod 21 moves the padding 27, and with it the belt 28 along conoids 29 and 30 to that side or the other n changes the speed of the exhaust pair 2 and, consequently, the amount of stretching, which regulates the number of the tape.
