Description

"

The invention relates to a machine tool industry and can be used in automated areas and mechanical processing lines when feeding and moving workpieces.

The purpose of the invention is to improve the reliability of the device by ensuring that the pallets move at the intersection of the conveyors with both conveyors simultaneously.

FIG. 1 shows a transmission device of pallets; a general view of FIG. 2 shows section A-A in FIG. one; in fig. 3 — node 1 in FIG. one,

 The proposed device contains a main conveyor 1, located at a right angle to it and intersecting with it conveyors 2, supplying them with trays 3 from a warehouse of blanks (not shown).

Each conveyor contains a frame 4 on which a drive, drive, tension (not shown) and deflecting 5 and 6 sprockets are mounted, placed in the upper and lower parts of the conveyor, transporting elements made in the form of two parallel endlessly closed chain contours 7, forming a load-carrying and idle branches of conveyors. Chain loops are a chain, for example, of the type of TRD with special links on which rods 8 are mounted. On the latter, rollers 9 are mounted on bearings with rubber rims with a spherical surface, the axles of which are parallel to the longitudinal axis of the conveyor, and 10, resting on idle-supporting conveyor guides 11,

Guides 12 are also mounted on the frame for the load-carrying branch of the conveyor and longitudinal guides 13, which limit the lateral displacement of the pallets 3.

In the intersection zone of perpendicularly arranged conveyors, the overloading section of the feeding conveyor 2 is located in the opening formed by the load-carrying branch of the main conveyor 1, which, by turning the deflecting sprockets 5 and 6, forms an arcuate section. The load carrying branches of both conveyors in the area of overload lie in the same horizontal plane.

In the zone of intersection of the conveyors at the stopping points of the pallet 3, limit switches 14 of the contactless 5 type and electromagnetic stops 15 are fixed on the metalwork.

The width of the opening should be less than the width of the pallet 3 by an amount equal to two radii of the arcuate section of the load-carrying branch. to The device works as follows.

A pallet 3 with blanks is installed by a stacker (not marked) of the warehouse on the feed conveyor 2 and 15 moves along the latter until it crosses the main line; m conveyor 1.

In the intersection zone, the limit switch 14 and the electrostatic stop 15 are triggered. programs. By conveyor

2 pallets 3 will proceed to the workplace (not shown), where the limit switches are also installed

3Q and electromagnetic stops. Pallet

3 follows from one workplace to another in accordance with a given program for the technological cycle. When moving any conveyor carrying the branch of its chain loop 7 with rods 8 and rollers

9 rolls with chain bushings along guide 12, and a single branch rolls along guide 11 with rollers 10 fixed also on rod 8.

Once in the intersection zone of the two conveyors, the pallet 3 is above the opening formed by the load-carrying branch with the help of deflection sprockets 5 and 6.

Here, in connection with the fact that the rims of the rollers 9 are made of rubber, the pallet always rests on the rollers of the load-carrying branches of both conveyors. At the moment when the pallet 3 passes through the intersection zone, there is always one conveyor, for example, the trunk is turned off, and the other, for example, the feed is turned on. The rollers 9 of the moving conveyor move the pallet 3 by adhering their surface to its bottom, and the rollers of the fixed main conveyor 1

rotate freely under the tray, supporting it and preventing it from moving in the direction perpendicular to the movement. Intersecting

in all conveyors, the displacement of the pallet in the direction perpendicular to the direction of movement is limited by the guides 13,
