Description

(54) LINE FOR UNPACKING SHEET PROTECTED MATERIALS

one

The invention relates to mechanical engineering, in particular, equipment for unpacking sheet materials, which are predominantly protected, and can be used in the reception departments of metal warehouses of engineering plants.

The closest to the invention to the technical essence and the achieved result is the line for unpacking the sheet protected materials containing receiving SOL, sheet transferor, fork tilter, device for opening sheets, drying chamber, device for wiping sheets, paired fork tilter, driving roller conveyors, roller table For stacking processed sheets, marking device and roller table for stacking labeled sheets 1.

A disadvantage of the known line is low productivity, since the process of removing the protected material from the surface of the sheet is done manually and requires, in turn, an increase in the number of service personnel.

. The purpose of the invention is to increase productivity.

This goal is achieved by the fact that in-line for unpacking of sheet protective materials containing a receiving table, sheet transferor, fork turner, de-preserver

5 sheets, a drying chamber, a device for wiping sheets, a paired fork tilter, drive roller tables, a roller table for laying treated sheets, a marking device and a roller table, Q, labeled sheets, the receiving table is equipped with a device for removing the protected layer from the sheet surface, made in the form of a portal equipped with a winding drum consisting of two parts, one of which is rigidly fixed on

15, the drive shaft, and the other, is skrenched with the first one with the help of hinges and springs, with guides attached to the upper part of the portal, on which a carriage with a knife is placed.

20 In FIG. Figure 1 shows schematically a line for unpacking sheet materials, a general plan view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a device for removing the protected layer from the surface of the sheet; in fig. 4 is a view B in FIG. 3; in fig. 5 shows the node I in FIG. 3; in fig. 6 is a sectional view BB in FIG. five; in fig. 7 - section G-Y in FIG. 5. The line contains a receiving table 1 with a device for removing the protected layer from the surface of the sheet, a transferor 2 of sheets 3, a fork turner 4, a conveyor 5 with drive rollers 6, a device 7 for re-preservation of sheets, a drying chamber 8, a device 9 for wiping sheets, a twin fork turner 10, left and right drive roller tables 11 and 12, roller table 13 for stacking finished sheets, marking device 14 and roller table 15 for stacking labeled sheets. The device for removing the protected layer from the surface of the sheet is made in the form of a portal 16 equipped with a winding drum consisting of two parts 17 and 18, while the winding drum part 17 is rigidly fixed on the drive shaft 19, and the winding drum part 18 is fastened to its part 17 with help, hinges 20 and springs 21. Guides 22 are attached to the upper part of the portal 16, on which a carriage 23 is placed, having a knife 24. To drive the carriage 23 into motion along the winding drum serves as an electric drive 25 with a chain linkage 26, for the driver Yes, the winding drum has an electric drive 27 for moving the portal 16 by means of a transmission mechanism 28. The winding drum may be made of wood. The line operates on two technological routes. According to the first technological route, sheet 3 is placed on receiving table 1, the device for removing the protected layer 29 from the sheet 3 is moved and installed over the edge of the sheet 3. Then, using an eccentric mechanism (not shown), the winding drum part 18 rotates around the hinge 20 relative to its part 17, wherein the springs 21 are expanded. Then, the edge of the protruded material from the end of the sheet 3 enters the resulting gap between parts 17 and 18 of the winding drum along the length, the eccentric mechanism rotates to its original position and the edge of the protected material is fixed on the winding drum. Next, the drum winds up the protected layer 29 as the portal 16 moves along the sheet 3 along the guides 22 by means of the electric drive 27 and the transmission mechanism 28. The electric drive 25 is simultaneously turned on, and the knife 24 cuts the cropped layer 29 wound onto the drum falls into the container (not shown), and the transferor 2 sheets shifts from the receiving table 1 sheet 3 onto the fork turner 4, which sets sheet 3 in a vertical position with the lower edge resting on the drive rollers 6 conveyor EPA 5. Further conveyor 5 sheet 3 moves alternately through the device 7 for reactivation of sheets where the last washed off from the surface of canning lubricant through suschilnuyu chamber 8 and through the device 9 for wiping the surface of the sheets where protirayuts. The sheet 3 is then moved onto a paired fork turner 10, which puts the sheet 3 in a horizontal position on the left drive roller table 1-1 to move it onto the roller table 13 for laying the processed sheets, where the latter are placed on pallets in bags (not shown). The line on the second technological route is similar to the work on the first technological route before the sheet 3 is fed to the paired fork turner 10, and then the latter puts the sheet 3 in a horizontal position on the right drive roller table 12, which moves it through the marking device 14 and then on the roller table 13 dl the stacking of the processed sheets, where the marked sheets are palletized into packages (not shown). The proposed line for unpacking sheet materials ensures the mechanization of the process of removing the protected material from the surface of the sheets and allows, thereby, to increase productivity, can be used in engineering and aircraft factories. Claims of the Invention Lines for unpacking sheet-protected materials containing a receiving table, sheet transferor, fork tilter, device for de-preservation of sheets, existing camera, device for wiping sheets, paired forked tilter, driving roller tables, roller table for laying treated sheets, marking device, roller table laying of marked sheets, characterized in that, in order to increase productivity, the receiving table is provided with a device for removing from the surface of the sheet of the installed layer, made in the form of a portal equipped with a winding drum consisting of two parts, one of which is rigidly fixed on the drive shaft, and the other one is fixed to the first one with the help of hinges and springs, and guides are attached to the upper part of the portal carriage having a knife.
