Description

The invention relates to welding, in particular, to devices for loading welding electrodes, and can be used in mechanical engineering for automating the processes for producing welding electrodes in nuclear engineering and boiler building.

The purpose of the invention is to increase productivity.

FIG. 1 is a schematic depiction of a device for loading welding electrodes, a general view; FIG. 2 is the same, side view; in fig. 3 - the same, top view; in fig. 4 - roller clutch; in fig. 5 shows section A-A in FIG. four.

The device comprises a welding frame 1, on which a mechanized conveyor 3 with a toothed belt 4, which has an inclination section 5 and a horizontal section 6, cantilevered and intended to load the electrodes 7 into the container 8, is fitted to a press conveyor 2 (not shown).

Inside frame 1, there is a lifting roller table 9, fixed by gears 10 on stub-roller chains 11, thrown over gears 12, which are fixed on tension and drive shafts 13 and 14, respectively. Shafts 13 and 14 are mounted in frame bearings (not shown).

The drive shafts 14 are connected to a drive 15 for moving the roller table 9, made in the form of an electric motor 16c by a gearbox 17, connected via a rigid coupling 18 to a Maltese mechanism 19. An sprocket 20 is mounted on the output shaft of the latter, connected by a stub-roller chain 21 with a gear holder 22 a roller double-sided clutch 23 rigidly mounted on a transverse shaft 24, which through bevel gears 25 is connected to drive shafts 14. The device is equipped with a drive for continuously variable movement of the roller table 9.

The drive of the stepless movement of the roller table is made in the form of an asterisk 26 on the separator 27 mounted on the gear case 22. The sprocket 28 is connected to an electromagnetic clutch 29 of the drive 30 of the roller table 9 connected to a worm gear reducer 31 connected through a coupling 32 with an electric motor 33.

In order to reduce jamming in a roller two-way clutch 23, the device is equipped with a shock-absorbing mechanism, made in the form of two counterweights 34, which can be mounted on cargo platforms 35 and suspended symmetrically relative to the lifting roller table 9 on the rods 37, which are passed through holes 36 in each counterbalance of the rods 37, which are connected to the rods 38 of the pneumatic cylinders 39 mounted on the frame 1. The cargo platforms 35 are connected to the roller table 9 by cables 40, thrown over the blocks 41 attached to the tension shafts 13. For maintenance tim of the respective positions of each counterweight 35 and the pad through the openings 42 therein skipped ropes 43 fixed to the bracket 44 of the frame 1.

The device works as follows.

Preliminarily, the container 8 is supplied to the lifting roller table 9 and is moved to the loading point where it stops when interacting with an electric cork (not shown). The horizontal section 6 of the mechanized conveyor 3 is slightly above the upper shelf of the container. The latter begins to be filled with welding electrodes 7. Then the command to turn on the drive 15 for stepping the roller table 9 is given, and the electric motor 16 is turned on through the gearbox 17, the coupling 18, the Maltese mechanism 19 begins to rotate the sprocket 20, which moves the roller-roller chain 21, which interacts with the toothed yoke 22 of the roller double-sided clutch 23. which, due to the rigid connection with the transverse scarlet 24 starts to rotate it. Through bevel gears 25, the rotation is transmitted to the drive shafts 14. The sleeve-roller chains 11, the envelopes of the gears 12 are driven, and the conveyor 9, fixed by the suspensions 10 on these chains, moves up and stops to fill the next shelf of the container welding electrodes. The stepwise movement of the roller table continues until all the shelves of the container 8 are filled. Then, at the command of the electric foil, the rotation of the roller roller table 9 is turned on, the container 8 is moved from the horizontal feed section 6 of the conveyor 3 and stops.

Then, pneumatic cylinders 39 are turned on, the rods of which extend and lower the counterweights 34 suspended on them to the cargo platforms 35. The drive of the stepless movement of the roller table is turned on, the roller coupling 32 is wedged, and after the electric motor 33 is turned on, the coupling 32, the worm gear 31, is wedge-mounted roller chain 28 connected with an asterisk 26 on the separator 27, begins to rotate in the direction opposite to the direction of rotation of the gear

clips 22 of the roller double-sided clutch 23. This rotation is transmitted through the transverse shaft 24 and bevel gears 25 to the drive shafts 14, while the live rolls 9 move continuously downwards, and the counterweights 34 compensate for the weight of the container 8 loaded with the electrodes 7.

After stopping the lowered roller table 9, a command is given to the pneumatic cylinders 39, the rods 38 of the latter are raised and the counterweights 34 are retained, eliminating their effect during the stepwise raising of the roller table when the containers are loaded with 8 electrodes.

Thus, equipping the device with an infinitely variable drive improves the performance of the device, since the roller conveyor smoothly, without stopping, descends to its original position, shortens the time of loading and unloading the electrodes into the container. Eliminating the inertial interface of the containers when the roller table stops, improves the quality of the electrodes, and the damping mechanism allows the coupling 32 to be wedged out smoothly, which prevents the container from being worn out and ensures a smooth movement of the roller table.
