Description

one

The invention relates to devices for gripping and transporting sheet material, which can be used for cleaning strips of metal from a cutting of a gas-cutting machine 5.

A device for gripping and transporting sheet material is known, comprising a height-adjustable beam, on which a trolley transported along it is mounted, carrying a traverse with electromagnets 1 located on it in a row.

A disadvantage of the known devices is the long duration of the cleaning process due to the fact that the strips are transported one by one.

The need to create a device that accelerates the process of cleaning the strips from the rack of the gas-cutting machine 20 is caused by large losses of machine time of the main equipment when cleaning by conventional sheet-laying machines. The cleaning cycle of one strip continues-. with an average of 3 Min (operations: magnet-25 capture, transportation, release with storage, return to the starting position). If, for example, a sheet is cut into 6 lanes with 2 tank waste (on modern 30

gas cutting machines installed 7 cutters), the cleaning process lasts 15-20 minutes. which represents from 15 to 25% of the total time of the technological process of cutting the sheet into strips.

Perhaps another solution to the problem by increasing the width of the cross member to the width of the original sheet. This makes it possible to remove all the lanes in one cycle, but requires the installation of a receiving device outside the rack, the dimensions of which are close to the dimensions of the rack. This causes a large loss of production area, which is eliminated from the process. The damage from such a decision can be estimated at 15 thousand rubles. in year. In addition, after cleaning the strips, they still need to be packaged, which causes additional manual labor costs.

The aim of the invention is to provide such a device for capturing and transporting sheet material, which would increase productivity by capturing and simultaneously transporting several panels.

The goal is achieved by the fact that the traverse is designed as a polyhedron.

and electromagnets arranged in a row are placed on each face of a polyhedron, while the traverse is mounted on a trolley with the possibility of rotation from a drive around its longitudinal axis.

FIG. 1 shows a diagram of the section for cutting gas sheets in the plan; in fig. 2 shows a section A-A in FIG. in fig. 3 shows a section BB in FIG. 2

Here, 1 is a rack, 2 is the location of the gas-cutting machine during stripping, 3 is a receiving device for storing and packing strips, including longitudinal beams 4 and crossmembers 5. Stands 6 serve for vertical movement of beams 7, which are suspended on cables 8 and through blocks 9 are centered with a drive 10. A carriage 11 is driven along beams 7, to which traverse 12 is suspended in the form of a polyhedron, and the rotational drive of traverse 12 is conventionally not shown. The edges of the traverse are equipped with limiters 13, which exclude the slipping of the trapped by electromagnets

in the inclined position of the traverse. The edges of the traverse are equipped with electromagnets 14c independent of the electromagnets of other faces, which allows the sequential capture of the cut strips 15. The operation of the device is controlled from the control panel 16. The operation of the proposed device is that the traverse 12 is installed above the retractable strip 15 the actuator 10 lowers the beam 7, turns on the electromagnet 14 on the lower face of the crosspiece 13 and the strip 15 is captured and further held. Then the yoke 12 is raised and turned around its axis at a predetermined angle until the free face of the yoke is set to the lower position, after which the cycle repeats: lowering the yoke, turning on the electromagnet, grabbing the strip, lifting

traverse, rotating it to the desired angle. After the traverse 12 is loaded with cut strips, it is transported to the receiving device 1 3. Here, the electromagnets 14 of the lower edge of the traverse 12 are turned off, and the strip is laid on the cross member 5. Rotation of the traverse G2 and alternate switching off of the electromagnets 14 of the corresponding faces follows the procedure for releasing the traverse and storing the strips . Additional devices may be installed on the receiving device to align the stack of strips along one edge. Removing the bag from the receiving device is carried out with an overhead crane using various devices, for example, traverses with jaw grips, etc.

The expected economic effect of 0 15 thousand rubles.
