Description

(54) ROTARY CLEARING DEVICE

one

The invention relates to the field of mechanical engineering, in particular to dividing devices.

A rotary dividing device is known, which contains a dividing gear disk, a latch, a rotary lever with a tooth, and a drive for moving the latch and a lever: /}

This device is complicated in construction and unreliable in operation.

In order to simplify the design and increase reliability in operation, the device is equipped with a thrust and a sleeve rigidly mounted on the lever, with the axis of the sleeve perpendicular to the axis of the dividing gear disk, the tooth is mounted in said sleeve with the possibility of reciprocating movement, and the traction is pivotally connected to lock and tooth.

FIG. 1 shows the proposed device, top view; in fig. 2 shows a section through section A-A of FIG. one.

The device includes a toothed separating disk 2 mounted in the housing 1, rigidly mounted on the shaft 3, having the possibility of free rotation on the shaft 3 of the rotary lever 4, equipped with a guide sleeve 5, in which

the tooth 6 is reciprocating, the pneumatic cylinder 7, the rod of which is pivotally connected with the pivoting lever 4, the latch 8, actuated by the pneumatic cylinder 9 and pivotally connected by the hard 10 with the tooth 6, adjustable stops 11 and 12, fixed to the housing 1.

The device works as follows. When air is supplied to the corresponding cavity of the pneumatic cylinder 9, the clamp 8 is released from the engagement with the separating disk 2, and the tooth 6, carried away by the thrust 10, enters the corresponding depression of the disk 2, moving progressively in the guide sleeve 5. Thereafter, air is supplied to the pneumatic cylinder cavity 7, its rod turns the lever 4 by moving it, and since the tooth 6 is in the cavity of the divider disk 2, the divider disk is rotated by the corresponding angle. At the end of rotation, air is supplied to the other cavity of the pneumatic cylinder 9, the latch 8 indexes the separating disk 2 in the new position and simultaneously disconnects the tooth 6. After that, the air is supplied to the other cavity of the pneumatic cylinder 7, and pulls it, turning the lever 4 in the opposite direction, deduces

tooth b on the axis of the next cavity of the toothed disk. The required angle of rotation of the dividing disc is adjusted using stops 11, 12 mounted on the housing 1 of the rotator.
