SU139590A1 - Installation for removal of raw bricks from the table of the turret press and its transfer to the shelf trolley - Google Patents

Description

Installations are known for removing raw brick from the table of a turret press and moving it to a trolley in a strictly defined position. They use buccal pneumatic, hydraulic or mechanical grips for each pair of bricks, mounted on a cantilever swivel rod, as well as pulsating belt conveyors-grousers, group bump loaders (combs) and depressors for trolleys.

In the proposed construction of an installation for removing bricks from a table of a revolving press, a grab-type lever system was used for buccal gripping of a brick remover, driven by a pull-out rod, which simultaneously brought the bricks removed from the press table to the edge. This makes it possible to combine the operations of shifting and tilting bricks,

FIG. I shows the mechanism for removing bricks from a press and installing it on a conveyor: in FIG. 2 is a section along the line A-A in FIG. one; in fig. 3 is a section along BB in FIG. one; in fig. 4 - detacher, side view; in fig. 5 - the same, front view; in fig. 6 is the same, top view without a conventionally not shown press; in fig. 7-pneumatic comb.

.A brick removal mechanism consists of a two-way system of spacers 1.2, 3З, interconnected by a hinged and movable crosspiece 4 on the rod 5, during movement of which the levers 6 with sponges 7 rotate 90 ° around the hinge of the hollow cross member 5. The product is gripped by the sponge with. using a cylinder-piston system of 5, 10 and // operating from compressed to three to five atmospheres of air, which is supplied by a flexible high pressure hose through a valve that turns on the air during the lowering of the mechanism for gripping the product. After this mechanism raise number 139590

up to 50 ll1 above the press and driver / 2, slides on rollers in the opposite direction with respect to the axis of the grouping conveyor - Moving the mechanism through the roller 14, bar 15, traverse 4 on the rod 5 and the articulated system of spacers rotates that the lever 6 with the jaws 7 goes from a horizontal position to a vertical one. At the same time, the hollow cross braces 8 come closer to the required adjusted distance, which provides a gap between the products of 15 mm. On command from the commanding device, air is released from the cylinders 9 and 16, and the levers 6 under the action of the spring 17 release the product, which is lowered onto the conveyor grouping.

The gripping and removal mechanism is located on the horizontal swing of the frame 18 and is driven in lateral movement by the driver 12. The frame 18 and the driver 12 receive a swinging motion from the grapple 19, which, in turn, receives a rotational motion of the shaft 20 through a bevel gear pair 2 / from the drive shaft 22. The shaft 22 has a direct connection to the press through an asterisk 25 mounted on the shaft and a plate roller chain 24. On the drive shaft 22 a curved disk 25 is mounted, through which the horizontal frame 18 is produced through the roller 26 and the pull 27 It moves up and down. Lowering the frame is necessary to grab a brick, after which a climb occurs.

In addition, the frame is raised during the movement of the gripping mechanism to the line above the pile conveyor 28 and lowered to turn the brick on the edge and place it on the conveyor belt. After the accumulation of sixteen pieces of brick on the gang conveyor 28, the pneumatic ridge 29 is taken up, which is lowered above the conveyor at the time of the collection of bricks. The comb consists of a frame 30 with pneumatic elements /, an air duct 32 and connecting sleeves 33. The pneumatic comb clamps the brick with its pneumatic elements and carries it away in the opposite direction, being located horizontally in the Direction of the standing trolley. The pnevmogrebevki operation is guided through the gearbox 34 and the electric motor 35. The pnevmogrebenka moves by means of a chain transmission 55 / sprocket 7 and an actuator 38. Simultaneously with the rotation of the pneumo-comb, the frame 39 of the elevator by the comb 40 and the gear wheel 41 rises to the corresponding free shelf of the trolley using the electric motor 42 s gearbox.

The mechanism for removing bricks and pnevmogrebenka work on compressed up to 5 atm. The control of all operations of the mechanisms is controlled by a command device which is driven by a drive shaft 22.

Subject invention

An installation for removing raw brick from a table of a revolving press and moving it to a shelf trolley consisting of a rotary puller with a buccal gripper for a pair of bricks, a pulsating grouping conveyor, a group pneumatic or hydraulic auxiliary loading device - fixed to the movable carriage . that, in order to combine the operations of shifting and tilting the bricks removed from the press table to the edge, the buccal gripper of the brick remover is equipped with a lever system of a clamshell type, which is activated by a retractable rod of the stripper shaft.
