Description

one

The invention relates to the tobacco industry, namely to installations for transport | cigarette smoking.

A device is known for supplying a series of machines with rod-shaped articles, for example, we have cigarettes, which contain means for the delivery of articles into a device, for example, a conveyor connected to it by a channel, means for distributing products in the form of transport vehicles, and a variable-capacity reservoir with a movable partition, branch of the channel.

A disadvantage of the known device is that voids or undesirable accumulation of products are formed in the mass of transported products, which leads to a decrease in Productivity.

In order to prevent voids in the mass of products or undesirable accumulation when the capacity in the proposed device is changed, the wall of the channel opposite the inlet of the tank is curved in the direction of the legacy to form two faces, the bottom of which is parallel to the movable partition, and the angle of the face of this face is horizontal planes more angle of repose products.

/ Upper face of the curved part of the cana wall

LA makes with a sharp horizontal yro.ni equal to the friction angle.

The top of the curved part of the channel wall is located below the upper level of the inlet of the reservoir.

The upper level of the inlet of the tank is p-aspolished under the lower branch of the feeding conveyor, in the upper part of the opening there is a pulley driven into rotational motion in both directions, and in the lower part an additional pulley, which is rotary in the direction of the products. In this case, the pulley is installed parallel to the conveyor pulley, on which the partition is fastened, which is driven in both directions, and there is a connecting bridge between the pulleys.

The canal wall adjacent to the inlet of the reservoir forms an acute angle with a horizontal angle greater than the angle of repose of the products.

FIG. shows a schematic of the proposed device, a longitudinal section; va fi1g. 2 - the same, the increased size of the left part of the device.

A device for feeding a series of machines with rod-shaped products, such as cigarettes, consists of a reservoir / variable container bounded by conveyors 2 and. 3 to the movable partition 4. Moreover, the partition is rigidly connected to the conveyors 2

and 3. A rotating roller 5 controls the flow of cigarettes fed to the reservoir by the conveyor. 6, above which a plate of 7 levels of cigarettes is placed in a channel 8. There are transport carriers 9–14 below the Reservoir. The intervals / 5 between the conveyors 12, 13 and 14 are used to supply cigarettes to the fed machines.

The stationary wall 16 is bent in the direction of the inlet 17 of the tank to form two faces / 5 and 19. The bottom face 19 is parallel to the partition 4 and the angle of inclination of this face relative to the horizontal plane is greater than the angle of repose of the products. The top face 18 constitutes with a sharp horizontal angle equal to the friction angle of the articles. In this case, the top, 20 of the curved part of the wall is lower than the upper level of the inlet 17, and the latter is located below the feeding conveyor 6, the pulley 21 of which bounds the opening / 7 in its upper part together with the pulley 22 of the conveyor 2. In the lower part, the opening 17 is limited by the pulley 23 conveyor 3. Between the pulley 23 and the driving pulley 24 there is a connecting bridge 25, and the pulley 24 may be inserted in both directions. The pulleys 22 and 23 are arranged so that the plane, passing through their axes, is angled to the horizontal, greater than the angle of repose of the products.

A rigid partition 26 is located between the sensor plate 7 and the pulley 22 in the zone of the upper part of the inlet of the reservoir, forming a sharp angle equal to the shear angle with the horizontal. The nlastin-1 sensor acts on photoelectric sensors 27 and 2-8 that control the operation of the conveyor 3.

The device works as follows.

: When all the machines powered by the device are working normally, the productivity of the conveyor a 6 is equal to the performance of the distribution conveyors 12, 13 and 14. At the same time, the level of cigarettes in the transition channel 8 stabilizes at such a height that the plate 7 remains in the neutral position, which corresponds to the stopped conveyor 3 and the pulley 22. The flow of cigarettes passes the channel. 8 by the opening 17 of the reservoir; the channel in the channel, the images of the annoto by the 19 Mina face and the pulley 23, and conveyors 12, 13 and il4 get into, and the machine, between intervals 15, goes to the fed machines. When the synchronization of feeding and dispensing of cigarettes from the device is violated, the level of the latter in Caial 8 is fixed by plate processor 7. If the supply of cigarettes is higher than the output, the sensor plate, acting on photoelectric sensor 28, turns on conveyor 3, which, due to the shift of the partition to the right, increases the reserve of cigarettes in the tank .

If the supply of cigarettes is less than the output, then the sensor plate 7 acts on the photoelectric sensor 27, turns on the conveyor 3,

but in the opposite direction, i.e., the partition 4 is shifted to the left. This compensates for the lack of cigarettes in the reservoir. When the delivery of cigarettes is greater than or equal to the output, moving them along the fixed wall 16 takes place under the pressure of gravity. Moreover, the angle and not dolzhev should be less than the angle of repose, in order to avoid the formation of cavities under the wedge apex 20, since this will allow cigarettes to cross the movement. In this case, the angle p must always exceed the angle T (rhenium.
