Description

(54) TRUCK STEP CONVEYOR

one

The invention is intended to transport parts from position to position and may find application in various industries.

Carriage walkway conveyors are known, comprising trolleys moving along the guides of the fixed frame, a frame movable from the drive with pushing stops, a carriage stopping mechanism made in the form of a brake tire.

However, such a conveyor does not provide accurate fixation of the carts at work positions.

In order to increase the reliability of the proposed conveyor in operation, the pushing stops of the movable frame are rigid, the folding dogs interacting with the pushing stops are fixed on the carts, and the stop mechanism is designed as a pivoting two-armed lever mounted on a fixed frame that interacts at the end of the movable frame with one shoulder fixed on drink cams, and the other shoulder with carts.

FIG. 1 shows the proposed stepping conveyor with carts in the initial position; pas figs. 2 - the same, with the carts in the locked position; in fig. 3 is a section along A-A in FIG. one.

Parts are placed on carts 1, in prisms or satellites 2.

Trolleys are equipped with locking lugs 3, and 4 dogs mounted in axles x

5, made folding in the direction opposite to the movement of carts.

The executive body is the cylinder

6, to the rod 7 of which a frame 8 is attached, reciprocating along the rollers 9. The rollers are mounted in racks 10.

On the frame 8 fixed the stops 11, with the adjusting bolts 12, and installed Cams 13.

The carriage retainers consist of pivoting arms 14, mounted on a common axis 15, fixed in bearings on a rack 16.

The levers have stops 17 on one shoulder, made in the form of adjusting bolts, and rollers 18 on the other. The trolleys are mounted on rails 19 attached to the frame 20 of the conveyor.

The conveyor works as follows.

The parts to be machined are fixed in the prisms of 2 carriages 1.

Oil is supplied to the rod cavity of the cylinder 6, and the frame 8 along the rollers 9 begins to move forward. By this, the pivot arms 14 will go off the cams 13 of the frame 8, then the stops

11 stumbles upon the dogs of 5 conveyor carts.

Trolleys will start moving to new work positions with frame 8.

When the carts approach the working positions, the cams 13 of the frame 8 rotate the levers of the 14 locking pins and, when the locking lugs of the 3 carriages meet with the lugs of the 17 locking lugs, the frame with the carriages will stop.

After processing the parts, to move the carts to the next position, the carts must be unlocked.

When supplying oil to the rodless cavity of the cylinder 6, the latter moves the frame 8 backwards.

When it moves, the cams 13 move away from the rollers 18 of the clamps, and the clamps go down under the action of their own weight.

Uncoupling carts.

Upon further movement of the frame 8, the stops 11 will approach the dogs 5 of the carts and fold them, the cams 13 will raise the pivot levers 14 of the cart locks, and the frame will again be in the initial position, after which the cycle of the step conveyor will repeat.

Subject invention

A trolley stepping conveyor comprising bogies moving along fixed frame guides, movable from

a drive frame with pushing lugs interacting with carriages and a stopping mechanism for carriages, characterized in that, in order to increase its reliability in operation, the pushing lugs of the movable frame are rigid, the folding paws interacting with the pushing mounts are attached to the carts, as a two-arm swivel arm mounted on a fixed frame

interacting at the end of the step of the movable frame with one shoulder with the cams attached to it, and the other shoulder with carts.
