(54) DEVICE FOR SECONDARY ORIENTATION OF PARTS

one

The invention relates to mechanical engineering, in particular to automatic orienting devices.

A device for the secondary orientation of parts is known, comprising a rotary drum with inlet and outlet radial channels, between which spring-loaded strips are installed, supplying and discharging trays and driving the rotation of drum 1.

A disadvantage of the known device is the impossibility of orientation of stepped parts having identical diameters at the ends.

The purpose of the invention is to expand the technological capabilities of the device when feeding the stepped parts.

The goal is achieved by the fact that it is equipped with a reciprocating movement from an additionally introduced drive and interacting with spring-loaded strips, a wedge and a part presence sensor located in the output radial channel and connected to the drum rotation drive and the wedge driving drive, with This spring-loaded strips are placed with the possibility of rotation relative to one another.

FIG. 1 shows a device for the secondary orientation of parts, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3–5 section BB in FIG. one; in fig. 4 - details oriented by the proposed device.

The device for the secondary orientation of the parts contains a feed tray 1 with a cutter 2, a rotary drum 3, in which between the input radial 4 and the output radial channel 5 are hinged on the axis x 6, spring-loaded spring 7 (Fig. 3) 8

15 at their ends, the rollers 9 and forming in the initial position the through hole 10, the base 11 with a wedge 12 and a sensor made in the form of an LED 13 and a photodiode 14, and an output tray 15. Orientable

, - the parts 16 have a step of the same length d (Fig. 4) of at least 1 length and differ in the total length and design of the other steps.

The device works as follows.

When the cutter 2 is triggered from the input tray 1, the orientable part 16 enters the radial inlet 4 of the rotary drum 3. If the orientated part 16 enters, in a position where its diameter step d is at the bottom, then it does not require reorientation the hole 10 formed by the strips 8 blocks the light beam from the LED 13 and a signal is transmitted from the photodiode 14 to move the wedge 12 in the direction of the rollers 9. The strips 8 move apart and the part falls through the input radial channel 5 to the output tray 15. If the orientable part 16 comes in a position where its diameter step d is at the top, then it requires reorientation, i.e., a 180 ° rotation. In this position, the part cannot overlap the LED 13, and this is a signal for turning the rotation of the drum 3 through 180 ° together with the oriented part 16 to align the input radial channel 4 of the drum 3 with the opening of the output tray 5. Part 16 falls into the output tray with a diameter step d down, i.e. again correctly oriented.

In order to provide orientation of the parts 16, for example tips of flexible brake hoses having a common feature in the form of the same diameter step d of length I (Fig. 4), but differing in length L, it is necessary that length A (Fig. 2) of the inlet radial channel 4 be The longest of the group of orientable parts Li, Tm.) r (Fig. 4), and the distance B from the upper surface of the strips 8 to the level of the sensor was no more than the length of 1 step of diameter d of the oriented part 16.

A lirra; In I. Application of the invention will allow to extend the technological capabilities of the device when feeding parts of the stepped form.
