Description

The invention relates to devices for the separation and single-piece delivery of cylindrical objects in automatic lines during transmission to subsequent transitions, namely, automatic winding machines, in particular to devices for dispensing reels to the winding zone.

The purpose of the invention is to increase the reliability of operation by reducing the impact loads.

FIG. 1 is a diagram of the device for the single issue of cylindrical parts at the time of submission of parts; in fig. 2 - the same at the time of issue of the part; in fig. 3 - the proposed device, side view.

A device for the delivery of cylindrical parts such as textile reels 1 and 2 contains an inclined Yushi direction 3 for gravitational transportation of the reels to the winding zone and the parts slinger, made in the form of a rocker arm 4 with running rollers 5 and 6, installed with the possibility of cyclic rotation from power actuator 7.

The yoke 4 is mounted above the guide 3 so that in its middle position the axis of rotation 8 passes through the center of a circle inscribed in a triangle, the bottom side of which coincides with the guide 3 and the side ones pass along tangential 9 and 10 to the rollers 5 and 6.

In addition, the axis of rotation of the 8 yoke

4 and the axes of the rolling rollers 5 and 6 have means 11 for adjusting their position relative to the guide 3.

To completely eliminate the impact of the rollers.

5 and 6, parts 1 and 2 establish the angle a between the axial lines connecting the axis of rotation 8 of the rocker plate 4 and the axes of the rollers 5 and 6 in accordance with the following relation:

a arcsin / dt-d

where D is the diameter of the part;

d is the diameter of the roller.

The axis of rotation 8 of the yoke 4 is positioned at a distance from the guide 3 equal to the radius of the parts being transported, and the rollers 5 and 6 are made of a shock-absorbing material, for example rubber.

The device works as follows.

In the initial position of the rocker arm 4 shown in FIG. 1, a gravity-type feed mechanism, for example, an inclined guide 3, feeds part 1 as far as it will go to roller 6, which occupies position I, while

The roller 5 in position II does not prevent the passage of this part, since it is as far as possible from the guide 3 and the distance between this surface to the forming roller 5 is equal to the diameter of the part.

„

After actuation of the drive / rocker 4, it deflects 5 left and takes the position shown in FIG. 2, in this case, the roller 5 rolls around the surface of the part 1, keeping it from rolling out. AT

position IV, roller 5 touches part 2 and fixes it, and roller 6, which has moved from position J to position III, does not prevent delivery of part 1 from the device, since it occupies the uppermost position.

After the actuator 7 is actuated again, the yoke 4 with the rollers 5 and b returns to its original position, while the roller 6 holds the part 2, preventing the free rolling of this and the next parts. In the minimum, when roller 5

occupies position II, to form a clearance for the passage of the part, the latter is fixed by roller b, which has passed into position I, and the device is ready to issue the next part.

Making the device for single-piece dispensing cylindrical details with rollers made of shock-absorbing material swiveling along the movement path of the parts significantly reduces production noise and prevents damage to thin-walled and fragile parts or other cylindrical objects, such as reels, which improves working conditions and saves considerable number of reels.
