Description

one

The invention relates to transport devices and can be applied in foundries at casting transshipment sites, where they are transported using plastic copiers.

Known scraper conveyors, made in the form of an endless chain with scrapers, rigidly mounted on the chain 1.

A disadvantage of the known scraper conveyors is the possibility of their failure during the transfer of the incoming bulk products due to the rigid attachment of the scrapers to the traction element.

The closest known device is a device for moving products, including a tray and an infinitely closed drive chain with hinged spring-loaded coaxial aprons and restrictive uior, and the second similar circuit is used to periodically issue products from the tray section serving as an accumulator in multiple feeds. 2

A disadvantage of the known device is the possibility of breakage, since the pushing stops (sanding elements or aprons), when receiving incoming bulk pouring, cannot deviate in the direction opposite to the chain movement, and the possibility of their deviation in direction

the movement of the chain does not allow the casting to be restrained when it is moved downwards from the tray.

The purpose of the acquisition is to increase

case of transfer of castings on the tray, smooth transfer of castings on the tray at the place of transshipment, ensuring the entry of aprons between the castings during their preparation, i.e. deviation of aprons and collisions with

castings.

For this, the aprons are provided with additional stops for interacting with the axes of the chain and counter-relief mounted on the canopy of the tray with the possibility of the interaction with the limiting stop.

The device contains endless lamellar chains 1 with rollers 2, which can roll along guide rails 3. The chain is placed between the tensioning sprocket 4 and the driving sprocket 5, connected chain 6 through the sprockets 7 to the driving shaft of the plate conveyor 8. On the axis x 9, which lamellar chains 1 are connected to, aprons 10 having a

the ability to rotate about the axis 9, the stops And are welded from the sides to the apron 10 and pressed through the springs 12 to the adjacent axes 9. On the aprons are also mounted brackets 13 with roller stops 14, which are located on the other side of the hinge axis of the apron. The rollers 14 can interact with the counter-rail 15 installed above the chute 16, which is attached to the metal structure 17 and serves to prevent casting 18 from the conveyor 8 to the conveyor 19 on it. The device works as follows. The aprons 10 with chains 1 (lower branch) move in the same direction and with the same or greater speed as the plate conveyor 8 due to the withdrawal of power from the drive shaft of the conveyor 8 by chain 6. Castings 18 that are located on the conveyor randomly when falling from it they fall on the aprons 10 and are lowered on the aprons into the tray 16, through which they move to the conveyor 19. If, on approach, the casting does not fall between the aprons, then the apron hitting the casting deflects the hinge opposite to the price movement, preventing the device from breaking, and not It prevents the casting from falling off the conveyor on the front apron, which lowers the casting as described above. The deflected apron after the casting falls under the action of the spring 12 returns to its original position before the stop 11 touches the axis 9. If the casting moves along the tray 16 slows down or stops due to insufficient tilt of the tray, the next apron moves the casting to the conveyor 19, since roller 14, interacting with counter rail 15, prevents the apron from turning in the opposite direction of the chain movement. The use of the device prevents the breakage of fragile products, for example, cast-iron thin-walled casting, when transferring from the upper level to the lower level due to the prevention of the acceleration of castings on the tray and their subsequent impact, which increases the yield of the suitable casting. In addition, the presence of a counter rail and a stop preventing the aprons from deviating in the direction opposite to the chain movement allows the proposed device to forcibly move the casting on the tray with a small angle of inclination. Apparatus of invention for transferring castings, including a tray with steep and gently sloping sections and an infinitely closed drive chain with hinged spring-loaded cantilever aprons and restrictive stops, characterized in that, in order to increase the reliability of the transfer of castings to the tray, the aprons are provided with additional stops for interacting with chains, and a counter rail mounted on a gentle part of the tray with the possibility of interaction with a restrictive stop.
