I 2, Grip according to claim 1, differing from each other, the brackets are mounted with pins and with the fact that the lifting plate is om, passed through the grooves, is provided with slots with grooves, and onto the plates of the plate.

The invention relates to the building materials industry and can be used for reloading and stacking rectangular products.

The purpose of the invention is the expansion of technological capabilities through

ensuring the capture of rows of bricks with significant fluctuations in their linear dimensions.

Fig. 1 shows the capture in the lowering moments on the formed group of bricks; figure 2 - capture, left and right; on fig.Z - group capture, the frame of which lies on the bricks; 4 - the same, at the moment of clamping the rows of bricks.

The gripper for transferring bricks contains a frame, on brackets 2 of which there are pivotally spring-loaded two shoulders levers 3, which serve to grip rows of the formed group of bricks, and on brackets 4 - pins 5, a lifting plate 6 with straps 7 attached to it with grooves 8 in which the pins enter, providing limited movement of the frame 1 with respect to plate 6 in the vertical plane. The cheeks 9 with notches on the pressure plane are pivotally attached to the short arm of the levers 3, and the equal arm of the rocker arms 1C) to the long shoulder. Similar rocker arms 11 are also pivotally mounted on the lifting plate 6. The ends of the rocker arms 10 and 11 are connected to each other by means of 12, with the outer arms of the rocker arms 10 of the levers 3 being connected to the lifting plate 6 tons of i 2 through additional links 13 and elastic compensators 14. The joints of the rocker arms 10 and II with the rods 12, as well as the rods 12 with the links 13 are made with the help of a spatial hinge mechanism, for example, a spherical structure. T gi 12 and links 13 connect the long shoulders of the ьkogov 3 located on each side

gripping, between, a, and with the slab 6, providing a suspended state of frame I with respect to the slab 6, rotates the levers 3 while gripping a row of bricks when the slab rises. The rocker arm system and the pull rod provides the necessary stroke for clamping bricks with any pair of levers 3 and redistributes

the clamping force on each row of the formed group, keeping its constant regardless of the linear size of the row. In addition, frame 15 has racks 15, on which

pivotally fixed stops 16, pressed against the stroke limiters 17 by means of springs and used for fixing the frame relative to the plate 6. The unlocking of the frame I with the plate 6 occurs when the stops 16 are rotated.

attached to the plate 20 of rubber.

The gripper for transferring bricks works as follows.

In the initial position (figure 1), the frame 1 being suspended from the plate 6 with

using racks 15 with stops 16, brackets 4 with pins 5, bars 7 with grooves 8, 9 levers 3 with divorced cheeks, it is lowered together with the plate onto the formed group of bricks at the loading position, with the stops 16 being supported by one of the arms onto the fixed supports 18, they turn, the second shoulder of the stops 16 slides along the plate 6 and, descending, descends. With

sliding stops 6 on the plate 6 when it is lowered, the speed of movement of the frame 1 slows down relative to the speed of the plate. After the lugs 16 slide off the plate 6, the frame 1 with stand, ikami 15 freely lowers at a speed higher than the lowering speed of the plate 6, which ensures the position of the lowered arms of the levers 16 at an angle one of the arms is tucked inside the supports 18), nАe plates 6. When lowering the frame 1, the levers 3 rotate to a predetermined angle, which leads to a decrease in the dilution of the cheeks 9, but not so much as to hinder the free coverage of them. clamped bricks. The stroke of frame 1, when it is lowered freely, depends on the accepted dilution of the cheeks, the weight of the frame, the strength of the brick, etc. The height of the supports 18 is selected. At the end of lowering the frame 1 by the plate 20 lies on the bricks 19, while between the pins 5 and the lower part of the grooves 8 there should be a gap allowing the arms 3 dp to clamp the bricks when lifting the plate 6 without interrupting the contact of the frame 1 s brick. At the moment of contact of the frame 1 with a brick, a command is given to the drive of lifting the gripper. When lifting, the movement from the cable is transmitted to the plate 6 and from it through the yokes 10 and 1I and the rods 12 with links 13 to the levers 3, which are additionally turned and the cheeks 9 clamp the rows of bricks. using the supports 18 by the stops 16, it lies motionless on the bricks, since at this moment the rigid connection between the plate 6 and the frame I itself is not the plate 6 is found Bbmie of the lowered shoulder of the stops 16). After the cheeks 9 of the arms 3 are in contact with the brick, it is clamped, and the grip with the bricks held together begins to rise. The stops 16 are released from the supports 18 and occupy a position under the slab 6. If the clamped rows of bricks have a different linear dimension, the corresponding rocker arms 10 and 11 are rotated through the desired angle and thereby compensates for even a significant difference in the lengths of rows while maintaining the same clamping force every p yes. Captured transfer bricks to the unloading position where the packets are formed. At the unloading positions, when the bricks in the gripper touch the pallet or the laid group of bricks, the frame 1 stops, the plate 6 descends under the action of springs and pull 12 with links 13, the levers turn, cheeks 9

consumption, freeing the bricks 19. Under the action of the descending plate 6, the stops 16, which are under it, turn, pass it and occupy a position above the plate. When lifting, the plate 6 through the stops 16 and the posts 15 fixes the frame 1 in relation to itself, which keeps the cheeks 9 in a diluted state. The grip is again returned to POSITION 1–1 loading. Cycle

his work is repeated. The clamping force of bricks is determined by the weight of the products, the weight of the frames :, the ratio of the arms and other factors.

A constructive mechanical gripping solution for transferring bricks expands its technological capabilities due to its ability to capture all rows of bricks of a formed dense group with significant fluctuations of their linear rows with guaranteed clamping force of each row.
