Description

Belt conveyors are known for distributing unit loads to transverse conveyors by means of devices mounted on a conveyor at the discharge point flush with its belt and made in the form of a section of a driven roller conveyor.

A disadvantage of the known belt conveyors is that. that during their operation it is not possible to automatically distribute the cargo to the cross conveyors and at the same time to control their dimensions.

Belt conveyor, made according to the invention, is devoid of this disadvantage. It differs from the well-known in that for clashing a load from the roll section of the npiiMeiieiUji drive chain transmissions. Operative chain drives, on which chains are pushed up above the rollers, are located between the rollers of the section in the rear of its section, counting in the direction of movement of the colliding load.

The automatic distribution of loads on cross conveyors and their control over dimensions is carried out through the use of limit switches, the blocking of which ensures the alternate filling of cross conveyors with cargo and the control of loads on dimensions.

FIG. 1 shows schematically the proposed belt conveyor, in plan with transverse conveyors; in fig. 2 - the proposed belt conveyor is combined with the drive unit.

The proposed belt conveyor, for example, for transporting boxers with bottles, includes the belt / conveyor belt bent under the roller table from long rollers 2, in places where people go to the bottle masters, through turn 142571-2iP roller table 3 and a straight chain conveyor 4, guides to the automatic removal of bottles from the boxes.

Crosswalkers in the transverse direction and the axle is fitted with a mechanical dashboard, an elliptical line consisting of four complete chain transmissions with protruding colliders over the rollers of the tachtkatel. Continuous rotation of the roller of the roller table and the periodic movement of the collider chains are carried out from the reducer b, the kinematic scheme of which allows to have one electric motor, due to the electric coupling, two rotations - continuous for rolls and periodic for the sliders depending on the arrivals. The operation of the conveyor belt is carried out as follows: drawers with empty dishes from a simple conveyor belt arrive with a break in the proposed conveyor belt. When the box comes to the roller conveyor, the normally open switch VK-211 closes, raises on the bracket above the roller conveyor, the gear reducer receives power and drives the collision mechanism 5, the speed of which is approximately 4 times the speed of the main conveyor belt. One of the chains which are knocking the teeth in the position before the arrival of the box opens the normally-closed switch VK-211 under the roller table; when moving the push button, the tooth releases the switch, providing a constant power supply to the electrofusion until the switch descends from the roller table in the transverse direction to the position opposite to the rotary roller table 3. At this time, the counter-mounted stalker tooth fits the normal-open control switch VK-211 and by opening it, de-energize the electromagnetic clutch.

If it is necessary to select a normal-closed switch VK-211, located above the roller table and connected in series with a normally-open switch, to one of the processes with a smaller height and connected in series with a normally-open switch, which turns off the power to the process of the box with a greater height, thereby providing its easy access to the next process. With the passage of small boxes of height, this switch does not work.

The installation of two normally-closed switches VK-211, connected in parallel, which provide the necessary supply of boxes in front of the slotting machine, is provided for processes to the bottle-washing maschines. When the process is filled with boxes, the switches are opened and the electromagnetic clutch of the reducer does not receive power. And the boxes begin to run straight along the roller table to the next process. In this way, continuous feeds are ensured for the full capacity of the line to ensure the full productivity of the automatic machineries.

The proposed belt conveyor is recommended for implementation by the Leningrad Economic Council.
