Description

one

This invention relates to automatic brick laying machines for drying trolleys.

A known mechanism for feeding frames, comprising feed and stepper conveyors with supporting elements, as well as a feeder.

A disadvantage of the known mechanism is the frequent jamming of the frames when removing them from the store to the stepping conveyor.

The aim of the invention is to increase the reliability of the frame feeding mechanism.

For this, in the proposed mechanism, the feeder is made in the form of a tilt-and-turn table installed between the supporting elements of mutually perpendicular feeding and stepping conveyors, while the supporting elements of the feeding conveyor are located above the stepping conveyor.

FIG. 1 and 2 show the stacker with the proposed mechanism.

The stacker contains a raw loading mechanism 1, a conveyor 2, a transnorter grouping 3, a storage hoist 4 with a fork-lift table and a frame feeding mechanism consisting of a feeding conveyor 5 of a package 6 with frames, a feeder in a lifting and turning table 7 and stepper conveyor 8.

A lifting-rotary table is located between the carrier branches 9 of the feeding conveyor 5 with the drive 10 and the movable tires 11 of the stepping conveyor 8.

The tilt-up table consists of a platform 12 supported on the rod 13 of the hydraulic cylinder 14 and movably mounted relative to the cylinder body 14 by means of guides 15 and crosshead 16 rigidly connected to the cylinder body 14, and a turning mechanism 17 with a hydraulic cylinder 18.

The step conveyor 8 consists of two fixed tires 19, two movable tires 11 and a carriage 20 with a pushing stop 21, reciprocating along the fixed guides.

The movable tires 11, which are rigidly interconnected by bridges 22, are connected to the tension spring 23, which ensures the idling of the stepping conveyor, and have pushing stops 24 that can be rotated in the feed direction of the frames.

The movement of the stroke of the carriage 20 with pushing the stop by the stop 21 is carried out through a chain

and an asterisk 25 from the drive mechanism 1 loading framework cheesy, turned on non-periodically, and the reverse movement - due to the load 26.

The step conveyor 8 is arranged perpendicularly to the feeding transnorter 5 and so

that the bearing branches of the 9th feed conveyor

located above the movable tires 11 of the stepper conveyor.

The automatic stacker works in the following way.

The molded bricks from the press (not shown in the drawings) are transported along the conveyor of the cutting machine to the two-belt conveyor of the frame loading mechanism 1. At the same time, a mechanism 28 for feeding the frame is fed under the two-belt conveyor to the bevelled drums 27. When the first brick is pressed on the switch 29, the drums 27, turning, lift the frame with a group of bricks above the level of the two-belt conveyor and transmit it to the drive roller table 2. Simultaneously with the command to turn the drums, the final switch 29 is sent to the gearbox 31, the sprocket 25, which through the chain transmits the movement in the direction of feeding of the frames to the carriage 20 with the stop 21, ensures step stepping of the frames located on the fixed tires i9 of the stepping conveyor.

The simultaneity and synchronism of the feeding of the framework is ensured by the fact that the movement of the formed brick from the press along a two-belt conveyor and the feeding of the framework by the stepping conveyor dried out from one drive.

The feeding of the frames from the stack 6 onto the fixed tires of the stepping conveyor is dried as follows.

A stack of 6 frames stacked with one row of frames rotating 90 ° relative to another is fed by a feed conveyor 5 to the position of the tilting turntable 7 and stopped along the circuit breaker 32, which is influenced by the front frame of the fed packet 6.

The last of the four frames located on the fixed tires 19 of the stepping conveyor 8 in the process of their stepping feed, when it leaves the zone of the tilt-and-turn table, frees the limit switch 33, which is constantly in the depressed position, and the most gives the command to feed the next group of frames to the stepping conveyor 8.

At the command of the final switch 33, the hydraulic cylinder 14 of the tilt-up table 7 lifts the stack of 6 frames above the uncrowded branches 9 of the feeding conveyor, and the mechanism 17 turns the lift-turntable together with the frame packet by 90 relative to its initial position. When lowering the tilt-turn table with the frame package of the lower row of the package, it passes between the carrier branches 9 of the feeding conveyor and is placed on the fixed tires of the stepping conveyor, and the package of the remaining frames is installed on the bearing branches of the feeding conveyor, since they are longer than the distance between carrier branches 9. In the following, the paver operation cycle is repeated.

Subject invention

A frame feeding mechanism comprising feed and stepper conveyors with carrying elements, as well as a feeder, characterized in that, in order to increase the reliability of its operation, the feeder is made in the form of a tilt-and-turn table mounted between the supporting elements of mutually perpendicular feed and stepping conveyors , while the bearing elements of the feeding conveyor are located above the stepping conveyor.
