SU62249A1 - Device for transferring molded grinding wheels from a press to a conveyor, etc. - Google Patents

Description

Devices are known that take a molded article, remove it from the press, turn it over 180 ° and stack the conveyor with a tapping.

A device is provided for transferring the ground grinding wheels from a press to a drying trolley or conveyor. The invention aims at the comprehensive mechanization of the production of grinding wheels with a diameter of WO mm and more and, as a result of mechanization, an increase in labor productivity and the elimination of defects.

Using the proposed device, the following operations are performed: delivery of the drying plate to the press, lining it on a circle, turning the circle, transporting the product to the trolley, COOLING the lower molding plate from the molded circle, placing the circle on the shelf of the trolley, returning to the molding press molding plate.

All these operations are performed by a device which is a mobile mechanical stacker with a turning mechanism. The device is equipped with two jaws, pivoting around a horizontal shaft, mounted on a vertically movable carriage, which, in turn, is mounted on a stand pivotally about a vertical axis.

in fig. I is the image described by the device Oe obok in FIG. 2 - kinematic diagram of the mechanisms of the device.

On the trolley 1, which is moving along the rails and carrying all the mechanisms of the device, is rotatably mounted a vertical axis of the frame 2 along which the carriage 3 moves in the guides, equipped with a jaw 4 and 4 for gripping and turning the product. The carriage 3 bears on itself an electric motor 5 with a worm gear and a drive for turning the trunnion that guides the frame 6, in whose slots the jaws are reinforced.

The lower jaw t, having a fork-like view and passing under the circle past the pins, is set in height with the help of the lead screw, depending on the height of the circle to be turned. This setting is made once before starting the whole batch of circles.

The upper jaw 4 serves as a support for the platform 7, to which the product is attached when turned over. Platform 7 is hinged so that it can swing in two mutually perpendicular planes; this enables it to self-align with the plane of the clamped circle. The jaw 4 moves along the slots for taking the platform 7 to the circle, i.e. for the gripper round jaws when turning.

Rollers are mounted on the carriage 3, which encloses the guide frames 2 to allow vertical movement.

For pushing the jaw from the platform onto the drying cart of a circle located on the drying plate, a pneumatic ejector 8 is used, which consists of two pneumatic piston engines.

In order to fit;} the curving and drying plate in the slots of the lower and upper jaws, pneumatic motors are mounted with clamps 9 of one-way action, having a cylinder, a piston and a spring for reversing.

The clamping of the circle with the phosphor when turning is carried out by the pistons of the hydraulic cylinder 10 mounted on the wrench b.

An electric motor II with a worm gear reducer 12 and a friction clutch is installed to rotate Paray 2 around the vertical axis.

The jaw carriage is raised and lowered by an electric motor 13 with a worm gear 14 and a drum 15 on which a cable is wound, bending around the block 16 installed in the upper part of the frame 2, and the blocks 17 of the chain pulley connected to the carriage 3.

The movement of the device on the rails within its working stroke is carried out by a hydraulic piston engine 18.

The movements of the carriage 3 are limited by limit switches operating automatically.

All movements of the device are accomplished with the help of three electromotive drives, one hydraulic drive, three pairs of pneumatic drives operating in parallel, and one separate pneumatic drive.

The circle is turned over by an electric motor 5, which informs the worm gear 19 to rotate the gear 20,

meshed with a gear wheel 21 mounted on a pin of the frame with a jaw.

The movable, lower jaw, as well as the upper one, is fixed mounted in the grooves of the frame with the pin. When the pin is rotated, the jaws are turned over. A limit switch is installed to limit and fix the position of the jaws.
