(5 ") FLOWING LINE FOR SHEET DISPOSAL

one

The invention relates to gas

cutting, in particular to the design of the production line for cutting sheets, which can be used in the procurement workshops of machine-building plants.

A known flow line for cutting sheets containing loader sheets with a mi-gripper, placed successively along the process flow, lifting-transporting carts with cutting tables with working tables parallel to the base, mounted on parallel rail tracks, cutting machines, supporting devices, as well as sheet unloader.

The drawback of the flipper production line is that the sheet to be cut is mounted on cutting tables placed on the support devices, without coordination relative to the table. In this case, the gas cutting machine

idle along the edge of the sheet and, with the distortions of the edges of the latter above the permissible limits relative to the mutually perpendicular axes of the machine, the sheet is manually coordinated directly under the machine, which entails a loss of time and, consequently, a reduction in the productivity of the production line.

The purpose of the invention is to increase productivity by reducing the time for coordinating sheets on cutting tables under gas cutting machines.

This goal is achieved by

15 that in the production line for cutting sheets containing loading sheets with magnetic grips placed successively along the process flow,

20 on parallel rail tracks, transporting carts with cutting tables with working planes parallel to the base, gas cutting machines, support equipment, and sheet unloader, the line is equipped with a stand for pre-orientation of sheets in the plane parallel to the base, placed between the loader sheets and lifting and transporting carts and made in the form of trellised frames with two opposite edges of the trellis frame parallel to the rail track of the lifting and transporting carts and machines for gas cutting, fixed stops are fixed on two adjacent edges of the lattice frame, and stops on movable adjacent edges are placed in the plane parallel to the base, Figure 1 schematically shows the proposed flow line, view in plan; figure 1; on fig.z section aa in figure 1; ° figure 4 - section bb in figure 2. The production line contains a sheet-loader 1, including a traverse with electromagnetic grippers for transporting sheet 2 from warehouse 3 of billets to stand k for pre-orientation of sheets mounted on parallel rail tracks 5 transport and transport trolleys 6, on which cutting tables 7, machines are installed 8 for gas cutting, supporting devices 9, 10-sheet unloader. The stand k for pre-orientation of the sheets is made in the form of a lattice frame 11, along the entire length of which transverse walls 12 are installed, carrying rotatable support heads 13 with eccentrically located rollers 14, as well as movable in a plane parallel to the base, stops 15c drives 16 and stationary stops 17- Stand C for pre-orientation of the sheets in a plane parallel to the base is placed between the 1-sheet loader and the load-carrying carts 6. The two opposite edges of the lattice frame of the stand k are parallel to the rail 5 unloading and transporting carriages 6 and cutting machines 8 for cutting gas, fixed stops 17 are fixed to two adjacent edges of the trellised frame, and stops 16 that are movable in a plane parallel to the base are placed on opposite adjacent edges. Lifting and transporting carts 6 are equipped with jacks 18, and supporting devices 9 are made with folding stops 19 consisting of strips 20 and 21. Point B (fig. base point for coordinating sheets 2. The line includes a series of parallel-installed gas cutting machines with loading and unloading positions. One stand k is provided for the entire line for pre-orientation of sheets 2 and one loader 1. The flow line works as follows. I Sheet 2, which is subject to a gas cutter, from the warehouse of 3 metals, is fed by the loader 1 with electromagnetic grippers to stand 4 for the preliminary orientation of the sheets along two mutually perpendicular axes and base point B, i.e. so that the sheet 2, located on the cutting table 7 and installed under the gas cutting machine 8, is always in the transverse direction at the beginning of the cut at the same point regardless of the dimensions of the sheets. From stand k, sheet 2 with loader 1 is fed to the cutting table 7 mounted on the folding stops 19 of the support devices 9 at the loading position. The lifting and transport bed 6, at the command of the control panel, approaches the loading position and removes the cutting table 7 with sheet 2 with jacks 18 and transports it under the gas cutting machine 8. Then, the lifting and transporting carriage 6 by jacks 18 places the cutting table 7 on folding supports 19 of support devices 9 located near the machine 8 for gas cutting, and itself follows the position that is required in the technological cycle. After the sheet 2 is cut by the gas-cutting machine 8, the transport and transport trolley 6, at the command of the control panel, approaches the cutting position and removes the cutting table 7 with sheet 2 with jacks 18 and transports it to the unloading position, i.e. under the unloader 10. Here jacks 18 the cutting table 7 with the sheet 2 is installed on the folding stops 19 of the support devices 9 located at the unloading position. After that, the unloader 10 with electromagnets of the cut parts is unloaded into containers. At this time, the lift truck 6 no ksmande from the control panel returns to the loading position, removes the next cutting table 7 with the oriented sheet 2 from the supporting devices 9 and transports it to the cutting position, then the cycle repeats. According to this principle, all sections of the line work. Due to the fact that the line is equipped with a stand for pre-orientation of sheets, mechanized coordination of sheets is carried out along two mutually perpendicular axes and a base point of the plane parallel to the base, which allows reducing the auxiliary time for preparing to cut the sheet and thereby increasing line productivity. The use of the invention yields an annual economic efficiency in the amount of ISOAS rubles. when cutting on the ling 600 pcs. sheets.
