(54) SEMI-AUTOMATIC LINE OF MANUFACTURING ROOFING STRIPS

I

The invention relates to semi-automagical lines, in particular, lines for the assembly and painting of sheet materials, mainly steel roofs, and can be used in repair and construction enterprises for the manufacture of wavy, painted or primed roof strips of the required length.,

The closest technical solution to the invention is a device containing technological processing, installed in a technological sequence, loading and unloading devices and

roller conveyor 1.

A disadvantage of the known technical solution is the lack of mechanical assembly of the sheets into strips.

The purpose of the invention is to increase productivity.

To achieve this goal, the roller table is made in the form of three sections.

equipped with autonomous drive and control, with the beginning of the second section of the roller table shifted in the horizontal plane relative to the first section, at least by the thickness of the sheet.

FIG. I shows the line layout; in fig. 2 is a view A of FIG. 1; FIG. 3 shows a section BB in FIG. I; in FIG. 4, view B in FIG. 1; FIG. 5 - node 1 on. one.

Claims (1)

The semi-automatic line contains a rack installed in the technological sequence for the original steel sheet (not shown), a vacuum transfer unit 1 with four vacuum suction cups 2, pushers 3 on the receiving table requested a bending installation 4, at the output of which the limit switch flag is set, and tilting 6 is profiled - nymi corrugated sheet 7. The tilter 6 is made in the form of a rotary frame from the drive with parallel mounted armor-; chic rollers. In the vertical position, the tilter is combined with the beginning of the first section of the roller table 8, while its rollers serve to hold the product. The rolling table 8 contains three sections, each of which has an autonomous drive and control. In each section of the roller table, the upper row of cylindrical non-driven supporting rollers 9 and the lower row of pairs of profiled hued rollers along the profile of the corrugated sheet are installed; and pressure rollers 11 on the other side of the line. The pressure rollers are spring-loaded on the axles to the springs 12. On the sides of the first section of the roller table are welding stations 13 with a control panel for the line, and in front of them is a Multiple device 14, by means of which the edges of the two sheets can be pressed to overlap. In the area of the clamping device, the beginning of the second section of the roller table is shifted in the horizontal plane to the bar of the sheet being welded. In the second section of the roller table, a tunnel-type painting chamber 1 with a mechanism 16 for displacement of paint sprays is installed, and a roof-layer drying chamber 17 adjoins it. Flags of limit switches 18-2О are set at the entrance and exit of chambers. The end of the third section of the roller table 8 is combined with a dropper, for which the section does not have supporting upper rollers from the side of accumulator 21, and the lower profiled rollers on the same side are mounted on a common horizontal axis 22, which can be rotated. Semi-automatic line works as follows. From the control panel installed at the welding station 13, a command is sent to the vacuum transfer unit I, which by means of pneumatic suction devices 2 takes from the foot of the roof sheets 23 on the railing of the roof and transfers it to the receiving table of the bending installation 4. Using the pushers 3, the sheet is set rolls roll forming installation 4, from which the sheet goes to the tilter corrugated, wavy form. When the sheet completely leaves the roll forming unit 4, the limit switch 5 is triggered, 24 the drive of the transfer unit 1 and the roll forming set 4 is turned off and the tilting device 6 is turned with the sheet into a vertical position. The tilter 6 is combined with the beginning of the first section pojtt raHra 8, which, when launched, transports the corrugated sheet in a vertical position to the welding station zone 13. In this case, the rear end of the sheet is installed at the beginning of the second section of the roller table. Then the same procedure is repeated with the second / sht, it is only stopped when the leading edge overlaps the back edge of the first sheet, after which the pressing device 14 is activated and two-sided welding of the sheets is started. Since the beginning of the second section of the roller table is shifted relative to the first, the next sheets during transportation from the first section do not abut against the end of the previous sheet, but come with a lateral touch. The welded sheets are moved by the second section of the roller table to the sheet length, then profiling and feeding into the welding zone of the third sheet is performed. This process is repeated until the complete assembly of the roof strip of a given length g. After welding to the strip of the last sheet, the front end of the strip enters the chamber 15 of the tunnel-type painting. This triggers the limit switch 18, which turns on the movement mechanism 16 with the paint sprayers in the paint chamber. When the end of the strip leaves the painting chamber, the limit switch 19 is released, causing the sprayers to stop working and the profiled rollers of the third section of the roller table mounted on the horizontal axis 22 are simultaneously turned to vertical position. When the roller table is transported through the drying chamber 17 following the chamber 15 colors, it is blown with hot air. When the output of the rear end of the band is triggered, the limit switch 20 turns off when. - the water of the third section of the roller table, the axis of the roller 22 of the dumper is rotated to a horizontal position, the roofing strip is placed in the rack of the accumulator 21. Then the cycle repeats. Claims of the Invention Semi-automatic line for the production of roofing strips, containing Technological equipment, loading and unloading devices and roller conveyors, characterized in that, in order to increase productivity, the roller table is made in the form of three sections equipped with autonomous drive and control, with the beginning of the second section of the roller table being shifted in the horizontal plane relative to the first section, at least on sheet thickness.
