SU105527A1 - Adaptation to carding, tape, etc. automatic tape numbering machines - Google Patents

Description

The subject matter of the invention is to adapt to carding, tape, etc., machines for automatic numbering of a tape number, including a stretcher mounted on the head of the paver, with conical exhaust rollers and a device for automatically moving the tape along the stretcher, made in the form of a spring-loaded lever ribbon guide funnel.

The proposed device in comparison with the known has a simpler design.

The peculiarity of the device is that the spring-loaded lever, mounted to rotate the wok of the vertical axis, carries the rollers located above the device and rotated by means of a pair of taper shakers from the vertical shaft of the laying machine.

FIG. Figure 1 shows the layout; in fig. 2 is a plan view; in fig. 3-curler and flatting rollers; in fig. 4-scheme of force dependence, determined yup4, their position of plush-coil rollers.

On the head of the paver, an exhaust device is mounted, consisting of a pair of conical exhaust rollers 1 and a pair of feeding cylindrical rollers 5.

A pair of cylindrical pliable rollers is located above the pair of feeding cylindrical rollers i in the perpendicular direction to their axes.

The axis 4 of the leading flatting roller, funnel D), the belt guide}, and the fixed axis 6 of the driven flatting roller are mounted on a spring-loaded pivoting lever 7 mounted on the sleeve поворачив turning on the ball bearing around the vertical axis 9. The slave flatting roller presses the leading plate. 70 mounted on the lever 7.

The leadpanne of the leading plus1 roller is produced through a pair of tapered gears / ./ from the vertical shaft 12 of the paver. From the shaft .1, rotation and rollers of the exhaust device are obtained (gear transmission, as shown in the drawing).

Fixed on the axis 4 of the leading flatting roller gear 13

rolls over bevel gear 14 in the direction of rotation of the latter. The rolling of gears 7L is counteracted by a spindle, 76, which holds the lever 7 and the axis of the driving flatting roller in a certain position.

The position of the flattening rollers 3 is determined by the force of pulling the ribbon through the funnel 5. This force is a variable value n depends on the thickness (number) of the ribbon. With a low ribbon number, this force is greater, and at high - less.

Variable force on the circumference flatting rollers.; determines the moment of their rotation, which determines the force developed on the gear teeth: lh and 14. The force acting on the gear axis 4 changes accordingly. It is always possible to attach two oppositely directed forces P to the axis 4, equal to the force acting on the gear tooth. One of these forces P, together with the force on the prong, constitutes a pair of forces, turning axis 4, and the other acting on the axis and through ball bearings on lever 7 in the direction of rotation of the drive bevel gear 14.

Since the force P varies depending on the belt number, the opposing spring 7o has a different tension, as a result of which the lever 7 and the flatting rollers .9 occupy a different position.

With a low ribbon number, when force P increases,, 75 is stretched by a large amount and rollers 3 occupy a position corresponding to a larger stretch.

With a high belt number, when the force P is reduced, the spring 7o is stretched by a smaller amount and the rollers 5 occupy a position corresponding to a lower stretch.

Thus, the incoming

into the funnels O and B, and 1, from the B of the instrument, the tape is automatically aligned.

Subject invention

Adaptation to carding, tape, etc. machines for automatic alignment of the tape number, including a stretching device mounted on the head of the paver, with conical exhaust rollers and a device for automatically moving the tape along the stretcher, made in the form of a spring-loaded lever with a guide belt funnel , characterized in that, in order to simplify the construction, the spring-loaded lever is rotatably mounted around a vertical axis and carries flatting rollers located above the exhaust zhnym device and driven in rotation by a pair of bevel gears of a vertical shaft coiler.
