Abstract

The invention relates to welding, in particular, to the construction of an installation for the manufacture of welded metal structures, mainly refrigerated shelves. The goal is to increase productivity by reducing the time for changeover of the switchgear when supplying usable and defective metal structures to it. The installation contains welding mounted on the base and connected by a transport device.

a machine, a device for adjusting welded metal structures, a chipping device, a quality control device with a distribution device 7 for feeding valid and defective metal structures on opposite sides of the longitudinal axis of the installation. The distribution device is made in the form of a stand 11 mounted on a base with a screw groove 23 and a straight linear length of groove 22. On the base there are mounted fingers mounted in the carriage 16 with the possibility of alternately placing from the cylinder 17 in the corresponding slots 22, 23 of the stand P The gravity reamer is made in the form of a hinged plate 14 on a stand 11, equipped with a tilt drive in the form of a cable 26, one faucet connected to the plate 14, and the other with a base. Depending on the signal coming from the welding quality control device, the carriage 6 with fingers inserts one of the fingers either into the screw groove 23 or inserts the other finger into the longitudinal straight groove 22 of the stand 11. When lifting the stand 11, the plate 14 rises or turns around the axis of the rack 11 by 180 due to the screw groove 23, or without rotation due to the longitudinal straight groove 22. In its upper position, the plate 14 is tilted by the cable 26 and ensures that the good shelves of the refrigerator are reset to one side or the defective shelves are reset to the other side relative to the longitudinal axis of the installation. 1 hp ffy 7 ill.

The invention relates to welding, in particular, to the construction of an installation for the manufacture of welded metal structures, preferably refrigerated shelves,

The aim of the invention is to reduce the time for readjustment of the switchgear when suitable and defective metal structures are supplied to it.

Figure 5 shows the installation, side view; figure 2 is the same, top view; in FIG. 3, view A in FIG. 2; figure 4 - view B in fig.Z; on fig.Z - section bb In figure 4; Fig 6 - the position of the plate when the welded metal structure is dumped to one side; nafigo7- the same, in the other direction.

The plant for the manufacture of welded metal structures, mainly refrigerated shelves, contains a base s on which the transport device 2, welding machine 3, rivetting device 4, edge fining device 5, welding quality control device 6 with switchgear for supplying valid and defective metal structures along different sides of the longitudinal axis of the installation. The device 7 comprises a frame 8, on which the bar 9 is mounted, the guide 10, the tilt-up column 1 connected to the lower end with the rod 12 of the lifting cylinder 13, and the upper end to the gravitational desiccator in the form of a plate 14 connected to the bar 9 through horizontal axis 15. The carriage 16 is connected to the cylinder 17 through the bracket 18 and the threaded tip 19, is equipped with fingers 20 and 21, mutually acting either with the longitudinal straight groove 22 or with a screw groove 23, made in the rack 11, the carriage 16 is mounted on 24 and secured together those with a cylinder 17 on the bracket 25 of the cable 26. The plate 14 is provided with a drive for its inclination, executed in the form of a cable 26 connecting the plate 14 with the guide 10. The installation works as follows.

The shelf of the refrigerator is transported by the transport device 2 from the welding machine 3 to the device of leveling 4, then the shelf is transferred to the device of the 5 ends of the edges and then

to the welding quality control device 6, after which the shelf is fed to the plate 14 of the rail 9 of the switchgear 7 when suitable and defective metal structures are fed to it. The rod 12 of the lifting cylinder 13 moves upwards in the guide post 11, on which the plate 14 is hinged on the horizontal axis 15. At the same time, depending on the signal from the welding quality control device 6, the carriage 16 is driven by the cylinder 17, moving on the rails 24 enters either the finger 20 into the longitudinal slot of the groove 22 or the finger 21 into the screw groove 23 of the stand 11, the plate 14 together with the stand 11 and the shelf of the refrigerator on it rises either with a turn on (FIG. 6) or without turning (Fig.7) around the vertical axis, and in its extreme the upper position of the plate 14, getting tilted, ensures the discharge of the shelves of the refrigerator in one direction or the other, thus producing. The fit is in one tau, the defective in the other.

The inclination of the plate 14 is ensured by the fact that it is mounted on a stand 11 sariirno with the possibility of rotation on a horizontal axis 15 and one side of it is connected by a cable 26 to a guide 10, while the cable 26 has a certain length and does not interfere with its free ascent to the required height , and turning it together with the pillar 11 around a vertical axis.

In a plant for the manufacture of shelves of refrigerators, the process of removing and sorting the shelves of refrigerators is mechanized, which eliminates the possibility of mass rejection, since when dumping several shelves of refrigerators, the plant stops working on the container for defective shelves.
