CS234826B1 - A gripping device for a material of rectangular shape placed one above the other with a gap - Google Patents

Abstract

The gripping device is intended for gripping prismatic-shaped material, such as steel sheets and bundles or bundles formed from them, if they are stacked with gaps above each other. The dimensions of the prisms can be different, but prisms of the same width must be placed in one stack. Access to the gripped prism is from above. The device allows for a remotely controlled or automated method of manipulation.

Description

4 234826

The invention solves the gripping of the material of the rectangular shape of the spit, the width, and the length of the spaced-apart spacing, which gap is created by the translation.

The gripping of the material of the prismatic shape, for example, the bits of width, width and length, and the bundled or unbound bundles formed therefrom, is predominantly hand-made even when these prisms are separated by a gap formed by the translations. Gripping allows gripping work when the prism is carried by the forks. The approach and distance is solved from the side, which requires free space wider than the width of the prism. The gap between the prisms depends on the fork dimensions. These circumstances reduce the use of storage space. With regard to the spit height dimensions of the prisms or the interspace height, it is the same from the ground plane. For these reasons, the transfer to the stacker method in the steel sheet warehouses without the use of shelves has failed. Mechanization and automation of the gripping action with the upper access to the prism impinges on the problem of reliably identifying the gap between the prisms so as to grasp the coarse pile, whereby the height and width of the prism can be varied to a considerable extent.

These drawbacks are eliminated by the device according to the invention, the principle of which is a separation. the beam to the main beam that is stabilized on the handling shaft and is provided with a stand to support the gripping beam from above, and to the support beam, which is provided to identify the first of the two at different edge widths and heights gap and seize the upper prism.

To this end, the auxiliary beam is vertically guided in the main beam and is vertically mechanized by the main beam. This movement allows the auxiliary beam to adjust to the height of the clamped prism. Depending on the length and stiffness of the retained prism, at least one cross member is provided on the sub-beam. Jaws are moved mechanically and transversely in each transverse direction. This movement makes it possible to adapt to the width of the prism. The claws are rotatably mounted on the vertical claws of the jaws. It can be secured mechanically by a actuator. In the unlocked state, the force of the force can deflect in both directions, but by the action of a set of two springs it returns to the equilibrium position after the deflection force is extinguished. The secured claw may be deflected upwards and also return automatically to equilibrium. The equilibrium position of the claw is identified by the sensor. The claw foot is provided with a gap in the vertical motion of the auxiliary beam by snapping it in place and, after being identified in the secured state, to support the prism during its transfer. In order to make better use of the storage area, when prisms of very different widths are stored, the crossbeams of the auxiliary beam are provided with symmetrically positioned spring-loaded barriers extending into the path of the claws. which is used to sort the jaws on these obstacles.It allows to access from above to grasp the table with open jaws to two and even more width.

The gripping device according to the invention allows for the mechanization of gripping the material of the prismatic shape with the complete exclusion of the human factor in this operation and in the preservation of the simultaneous use of the storage panels. The grip is carried out with the upper access to the material, thereby allowing it to be stacked in higher heights and eliminating the needy and dangerous human activity. By solving the gripping mechanism of the sheet metal or sheet bundles, the most serious obstacle to automating the sheet metal folding is overcome.

The main beam 1 is stabilized by the ropes 2 on the handling crane and is supported by a base 3 and a vertical guide for the auxiliary beam 4. The auxiliary beam 4 is fixed to the main beam 1 by a guide 5 and the relative movement is defined by the steps 7. \ t fixed beams 6 with crossbars 8. The beams 8 are provided with a symmetrically disposed system of hinged barriers 9, the pre-tensioning of which is provided by the spring 10 and swiveling the sensor, and symmetrically positioned by a plurality of stops 11. The movement is ensured by the actuators 13. On the vertical arms of the jaws 12 there are rotary claws 14 provided with return springs 15, mechanically operated fuses 16 and an equilibrium sensor 17.
