Description

The invention relates to ancillary devices for the orientation of parts and, in particular, to devices for the orientation of core and glass-like parts having a large ratio of length to diameter.

Known rotor orientation piece parts containing evenly spaced around the circumference of the rotor mechanisms of secondary orientation, made in the form of rotary cylinders 1.

The disadvantage of the rotor is its large size with the orientation of the l-dimensional parts, which increases their inertia.

In order to reduce the size of the rotor by reducing the stepping distance between the orientation mechanisms during the orientation of lengthy parts, the reciprocating rotary cylinders are installed with the possibility of radial movement and rotation around its axis in a vertical plane passing through the axis of rotation of the rotor.

FIG. 1 shows a rotary automat, longitudinal section; in fig. 2 -

fragment of the rotor orientation (orientation mechanism); in fig. 3 is a section along A-A in FIG.

The orientation rotor contains a hopper 1, a shaft 2, a drum 3 is rigidly fixed on it, in the slots of which are placed sliders 4 interacting with agitators 5, devices for transferring parts from

0 bunker 1, made in the form of a vertical channel 6, orientation mechanisms 7, placed evenly around the rotor circumference and made in the form of rotary cylinders 8,

5 placed on gates 9 with the possibility of radial movement from the cam 10 and rotation around its axis in a vertical plane passing through the axis of rotation of the rotor

0 due to the fixed gear rack 11, the cut-off devices 12 interacting from one cam 13. The rotor is rotated from the gear wheel 14, and the parts from the mechanism

5 orientations fall on the transport chain 15 for transfer to subsequent operations.

The rotor orientation works as follows. When the shaft 2 rotates, the turners 5 are activated by the movement of the sliders 4, interacting with the slotted cams. Simultaneously with the rotation of the rotor, the gates 9 from the cams 10 are set in motion, on which the through holes and the swivel cylinders 8 of the orientation mechanisms 7 are placed. The parts are protruding from the hopper. 1 through the agitators 5 into the vertical channels 6 pre-oriented with respect to its vertical axis and passing to the orientation mechanisms 7. The alternate arrival of parts into the orientation mechanisms 7 occurs due to the sequential actuation of the cut-off devices 12 from the cam 13. Each part, depending on its position enters the recess in the cylinder 8 and, turning back 180 °, changes its orientation. In another case, the part is correctly oriented through
