Abstract

The invention relates to lifting devices, in particular, to electromagnetic grippers, intended for single piece loading of steel products from a stack of similar products. The purpose of the invention is to increase reliability. The device comprises a frame 1 with longitudinal grooves, on which rollers 4 are installed by means of rollers, on which attracting grippers 8 are hinged. In the middle part of frame 1, on longitudinal grooves, by means of rollers 9, a hinged parallelogram 10 is mounted, the upper levers 11 of which are hinged to the upper hinge 1, on which is placed the counterweight. The lower arms 14 are connected by a lower hinge, on which additional grippers are mounted. When a traverse is taken from a stack of products, the load bends in the middle part under the action of an additional gripper, which continues to interact with it in the direction opposite to that of the grippers 8. 9 Il.

Description

Fiá.1

The invention relates to cargo-taking devices, in particular Electromagnetic grippers, intended for single cargo handling of steel products of various dimensions and geometrical shape.

The purpose of the invention is to increase the reliability of the device in single piece cargo handling of products of various dimensions and geometric shape. FIG. 1 shows the proposed device, a general view of FIG. 2 - the same, top view; in fig. 3 - section A-A in FIG. 1} in FIG. 4 — device at the moment of capture of the sheet stock | in fig. 5-9 are diagrams of the seizures of goods differing in dimensions and geometric shape.

The device comprises a frame 1 with longitudinal slots 2 made of a sheller (FIGS. 1 and 2). On the lower half of the Ki-paz 2 by means of the rollers 3, the BTEHbi axis 4 is mounted on which the holders 5 are mounted. Each of the holders has a rod 6 mounted in the required height, for example, with a bolt 7, each. by gripping 8 of the attractive type, it is harnessed in its lower part,

In the middle part of the frame 1, on longitudinal grooves 2, by means of rollers 9, a pivotally parallelogram 10 is mounted, the upper arms 11 of which are pivotally connected to the upper hinges 12 (Fig. 3) and a counterweight 13 placed on it. The lower levers 14 are connected to each other by a lower hinge 15, on which additional grippers 16 are installed (FIG. 3).

To limit the movement of the rollers 9 of the parallelogram 10, the movable stops 17 are fixed on the frame 1, for example by screws 18, with the possibility of their movement along the longitudinal grooves 2 and the fixed stops 19 (Fig. 2). To ensure the capture of products of 20 different sizes, each axis 4 is connected with Pa 1 by a setting mechanism 21 for the size-type screw-nut type.

The device works as follows

To capture sheet products from, i

the package on him down the device, hung by the upper hinge 12 on the lifting mechanism (not shown), with additional grippers

16 abut against the surface of article 20, and frame 1 continues to descend along with electromagnets. At the same time, the upper arms 11 move apart from their own weight of the counterweight 13 by rolling from their rollers 9 (FIG. 2) along longitudinal grooves 2. The movement of the rollers 9 is limited by fixed stops 19. At the moment of contact of the grippers 8 with the surface of the product 20 onto the clamps 16 and 8, the supply voltage and the upper sheet, i.e. The product 20 from the package is attracted to said electromagnets (Fig. 1).

When the device is subsequently lifted, frame 1 together with the upper hinge 12, the counterweight 13 and the claws 8, to which the product 20 is pressed by the magnetic field, moves upward, and the upper 11 and lower 14 levers of the hinge parallelogram 10 move closer along longitudinal slots 2 by means of their rollers 9 until the latter interact with the stops 17, and thereby provide a downward movement of the axis 15 with the grippers 16 (Fig. 4).

As a result, when the device is lifted, the sheet-product 20 bends in its middle part and is easily separated both from the bag and from the underlying sheets. Then the product 20 is moved to the next technological position, where the device is lowered and the power of the grippers 8 and 16 is turned off.

For cargo handling, products 20, differing in overall dimensions and geometrical shape, the device can be reconfigured: in overall dimensions by moving in a horizontal plane by the mechanisms 21 settings of the grippers 8 fixed on the axis 4 with rollers 3, in the geometrical shape of the products by setting the movable stops 17 with screws 18 and vertical movement in the holders 5 of the rods 6, followed by fixing them with bolts 7.

The use of the proposed electromagnetic load gripping device will reduce the range of cargo captures when reloading products of various dimensions and geometric shape, as well as increase labor productivity approximately

Claims (1)

Claim 1. A load gripping device containing a frame, a suspension unit and an abutment for engaging with the load, connected to it in its middle in the upper and lower parts, respectively, and attractors of the attracting type mounted on rods arranged along the edges of the frame pivotally with respect to the horizontal axis characterized in that, in order to increase reliability, the frame is made with longitudinal grooves, and the emphasis is formed by an additional grip of a longitudinal movement, and the upper hinge is a counterweight, with an additional grip azmeschen 10 on the lower parallelogram hinge pivotable about a horizontal axis, and the suspension assembly is connected to the top hinge of a parallelogram, fifteen . 2. The device according to p. 1 ,. due to the fact that, in order to ’/ expand the range of captured loads, the gripper rods are mounted on the frame with the ability to move 20 along it, and the grips are placed on the rods with the ability to move along the latter.
