Description

The invention relates to plate-chain conveyors intended for semi-automatic sorting of packages into a large number of directions, distribution of newspaper packs to workplaces and similar production processes in postal enterprises.

Plate conveyors equipped with carriages, platforms of which are made tilting around trunnions, mounted on the bogie frame by means of platform-mounted rollers that interact with the tires installed at the place of unloading are known.

A disadvantage of the known conveyors of this type is that the rotation of the platform (table) and, consequently, the dumping of the transported piece cargo at the selected place cannot be controlled from the control panel.

In the described conveyor, in contrast to the known arbitrary unloading of the parcel, one of the positions located along the conveyor is dried by means of a moving roller mounted on the turntable, which enters the upper or lower branch of the guide curves installed at these positions, and the direction of the roller in the corresponding branch is assigned on the control panel.

FIG. 1 shows a general view of the conveyor, side view; in fig. 2 the same, top view; in fig. 3 is an LL section of FIG. one.

The lamellar chain conveyor mainly consists of the following units: frame 1 of the conveyor, motor group 2, traction device 5, screw device 4, blocks of curves 5, turntables 6 and control panel 7.

The frame of the conveyor is welded from angle steel, on it there are reinforced runners, blocks of curves, supports and other details of the conveyor. Two pro. № 113584- 2 -

intermediate frames 8 border one section consisting of two blocks of curves.

The motor group consists of an electric motor, a worm gearbox and a V-belt transmission. The installed three pairs of stepped pulleys at the transmission make it possible to have three different speeds of movement and, accordingly, three values of conveyor productivity.

The traction organ is a bush-roller chain, on which the clips (carriages) that support the tilting platforms (tables) are fastened.

A screw tensioning device intended for tensioning a chain consists of two tension screws abutting the conveyor frame.

The blocks of curves serve to carry out the rotation of the carriage table, necessary for the discharge of the transported cargo into the corresponding slots 9, which are located on both sides of the conveyor; Each slot has a block of curves and magnets with contacts corresponding to any one combination on the control panel. The curve block is a welded from the corners structure, forming three guide branches (stream): straight, upper and lower. For the direction (run) of the roller, the upper and lower branches are provided with arrows, which are translated using electromagnets.

The turntable is a square plate hinged on the carriage. A kerchief 10 is hinged to the slab, carrying a comb // with a set of plates and a roller 12, which moves in guide blocks. The table is tilted to one side or another along the conveyor movement when the roller enters the upper or lower branch of the block.

The control panel is attached to the conveyor frame at the point of loading the parcels 13 and serves to control the electromagnets, with the help of which the arrows of the curve blocks are transferred.

When choosing the right direction for the next load, the worker at the console presses the corresponding buttons assigned to this direction, which rotate the comb plates fixed on the kerchief of the turntable. At the approach of the gusset plate to the place of discharge (schlyuz), the turned plates of the comb, in interaction with the plates installed at the gate, close the electrical circuit of one or another electromagnet. The latter, when triggered, produces a rotation of the arrow, which directs the turntable roller to one of the branches of the curve block. This rotates the table and dumps the transported load into the corresponding drive.

The number of directions depends on the number of buttons included in the console and the number of simultaneously working comb plates.

Subject invention

Claims (2)

1. A plate conveyor equipped with carriages, platforms of which are tilted around the trunnions mounted on the bogie frame, by means of rollers mounted on the platforms, interacting with the women installed at the place of unloading, and intended mainly for sorting postal parcels in several directions, different that for the purpose of arbitrary unloading of the parcel at one of the positions located along m; the exporter, the axles of the trunnions are oriented along the conveyor, and the platforms are equipped with pivoting Yelnia stops, trailing one of the discharging places electromagnets controlled unloading schipami guides. 2. The form of the conveyor according to claim 1, characterized in that, in order to perform the rotation of the respective stops in the operating position from the central control panel, in the path of the carriages are installed the stoppers moved by electromagnets and acting with the stops when the carriages pass.
