Description

The invention relates to a machine tool industry, to transport devices, mainly to conveyors of automated lines, with orientation of parts in the process of transporting and can be used when orienting sufficiently heavy parts (such as flanges, hubs, discs and so on with a ratio of height to diameter less than 1 ) with an unprocessed bottom surface, with lines on the side surface and turning them during transport.

The aim of the invention is to improve the reliability of the device.

FIG. 1 shows a device with two parts (one - before orientation, the second - after orientation), a plan view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 1, the detail is depicted at the moment of contact with the chains of the conveyor; pas figs. 4 - the same, the detail is depicted at the moment of contact with the conveyor chain and the plate.

The device for transporting and orienting part 1 with a protrusion (Fig. 1-4) contains two vertically closed traction organs in the form of infinite prices 2 and 3, the upper branches of which rest on the guides 4 and 5 fixed to the frame 6, and the lower ones branches are kept from sagging with blanks 7 (Fig. 2). The slats 8 and 9 (figs. 2-4) fixed on the frame 6 limit the lateral displacement of the part 1. An emphasis 10 for orienting the part 1 is mounted on the frame 6 and is made in the form of a roller with the possibility of rotation around a vertical axis.

The bottom surface 11 (Fig. 3 and 4) near the protrusion 13 of the part 1 when it is in contact with the chains 2 and 3 is located above the surface 13 of the plate 14 with the gap HI (Fig. 3).

The sprocket 15 is mounted on a shaft 16 mounted in bearings 17 on frame 6 in the zone of plate 14 below the surface of the upper branches of chains 2 and 3. On the eccentric neck 18 of shaft 16 a support 19 is mounted, which is in constant contact with chain 3. Support surface 20 details 1 is located above the chain 2 with a gap H2 (Fig. 4) when the bottom surface 11 of the detail 1 contacts the plate 14 and the surface 20 with the chain 3.

The protrusion 21 (Fig. 1) when rotating parts 1 relative to the stop 10 comes into contact with the side surface 22 of the strap 8.

The device works as follows.

Parts 1 in an arbitrary angular position are mounted on endless chains 2 and 3, the upper arms of which are continuously moving in guide bars 4 and 5. The conveyor drive is not shown in the drawing.

Parts 1, limited in the transverse direction by strips 8 and 9, are transported on a conveyor to the stop 10. There may be three options:

1) the center of the part 1 coincides with the axis of the conveyor, the part is in the oriented position and regardless of the position of the movable support 19 passes unhindered by the stop 10;

2) at the moment of approach of part 1 to the stop 10, the movable support 19 is at the top, while the bottom surface 11 of the part near the protrusion 12 contacts the top surface 13 of the plate 14 and the part rotates around the contact point by moving the part on the chain 3, overcoming only the resistance force from the friction details about the plate 14;

3) at the moment of approach of the part 1 to the stop 10, the movable support 19 is at the bottom, while the protrusion -12 of the non-oriented part 5 contacts the stop 10, abutting on which the part rotates, overcoming the moment from the friction forces of the part on the chains. 2 and 3.

If, due to the increased adhesion forces between the bearing surface of the part and the chain

 2, the moment preventing rotation of the part is greater than the moment that ensures the rotation of the part relative to the stop 10, then the rotation stops before the movable support 19 as it lifts tears off the bearing surface of the part from the chain 2, thereby ensuring unhindered rotation (see option 2 ).

The rotation of the shaft 16, providing the lifting of the movable support 19 due to the eccentric cheek 18, can be carried out

0 both directly from the conveyor chain and from an independent drive.

In the course of orientation, the part 1 rotates around the stop 10 counterclockwise until the protrusion 21 of the part 1 is in contact with the side surface 22 of the bar 8.

5 Next, the part 1 is rotated already relative to the protrusion 21, and its protrusion 12 slips relative to the stop 10 and the plaque 14 by moving the part on chains, then the oriented part moves on the conveyor in the direction of transport.
