Description

The invention relates to lifting devices for transporting products, in particular to devices with permanent magnets, and can find wide application in the metallurgical and machine-building industry during unloading and loading operations.

The purpose of the invention is to increase reliability and convenience by automating unloading.

Figure 1 shows the device, a general view; figure 2 is the same, side view; fig.Z - node 1 in figure 2; 4 shows a kinematic connection of a safety pickup with a gripping magnet, side view; in FIG. 3, view A in FIG. 4; figure 6 - section bb in figure 4; figure 7 - section bb In figure 5.

The load gripping device comprises a frame 1 consisting of two uprights 2 and 3 and a base 4 on which a lifting system 5 with a flexible thrust 6 and a drive 7 is mounted. The pick-up body includes a permanent magnet 8 which is kinematically connected with head plate 9 and brackets 10 and 11 through actuator 12 mounted on the basis of a discharge casing 13, the drive shaft 12 being connected to head plate 9, and the latter through two racks 14 with brackets 10 and II fixed on them, rigidly connected to the magnet 8. frame 1 attached bracket Teyns 15 with arms 16 fixed on the trays 17, mounted with or without free support on the brackets 10 and P. At the ends of the pillars 2, dampers 18 and 19 are mounted, consisting of body 20, spring 21, support sleeve 22, washers 23 and nuts 24

The device is usually installed in a continuous line an automatic line, where it is necessary to remove ferromagnetic products from fragile objects, for example, close the neck of the sprues of the ceramic molds to obtain exact castings, and transfer them to another operation, producing only reciprocating movement in a vertical flat bones.

The device works as follows.

Products are supplied under the magnet. At 7, through the load-lifting system 5 of the flexible pull 6, the traverse-, su 9 and the casing 13 with the supports 14 and the brackets 10 and 11 are lowered down the supports 2 and 3, the base of the casing reaches the dampers 18 and 19, while the brackets 10 and 11 racks 14 allow tray

17 tilt due to the rotation of the levers 16 around the hinges of the brackets 15, without obstructing the magnet 8.

The whole system with a magnet 8 compresses with its mass the springs of 21 dampers

18 and 19, adjusted with nuts 24 so that there is a gap between the product and the lower part of the magnet housing 13, which ensures the attraction of the products to the housing and prevents the 1st magnet from lowering onto the products and deforming or destroying them.

The actuator 12 lowers the magnet 8 to the bottom of the discharge casing 13. The products are attracted to the bottom of the casing 13 of the magnet 8.

After the products are captured by the actuator 7, the system is raised with the magnet 8 and the products upward, while the brackets 10 and II racks 14 drive the tray 17 through the levers 16 to the initial position, i.e. the tray 17 is under the articles held by the magnetic beam.

After lifting, the actuator 12 is turned on, which raises the yoke 9, the strut 14, the magnet 8, which increases the gap between the bottom of the casing 13 and the magnet 8 and weakens the force of magnet attraction of the products. The products are torn off from the discharge casing 13 and fall onto the tray 17, from which they roll into the container.

Claims (1)

Invention Formula A load gripping device containing a frame with supports, mounted on the frame movably from a drive in a vertical plane, a magnetic gripping body and an L-shaped safety catch hinged to the frame, kinematically connected to a magnetic gripping body drive, characterized in that, in order to increase reliability and convenience of work by automating unloading, it is sn, abrasive is movable in a vertical flat network mounted on supports and covering the magnetic gripping casing, made of non-magnetic Methods and material, and with the possibility of support frames arranged on the ends of dampers reacting with a casing, wherein the working arm of the safety pickup, located between the housing and gripping the product, is inclined tray.
