RU2295490C2 - Batcher for liquids - Google Patents

Abstract

FIELD: arrangements for batching.

SUBSTANCE: batcher comprises distributing head, air pipe, valving member mounted in the line for supplying liquid to the batcher, pickup of the presence of container, and control device. The batcher additionally has pipe for supplying liquid to the container, pressure gage of air in the container, pressure gage of liquid at the entrance to the batcher, and additional air pipe. The pipe for supplying liquid to the container is mounted inside the distributing head and is in communication with the line for supplying liquid to the batcher. The additional air pipe is mounted concentrically on the bottom part of the main air pipe. The gage of air pressure in the container is in communication with the air space of the container. The pickups of the presence of the container, the gage of liquid pressure at the entrance to the batcher, and gage of air pressure in the container are connected with the control device that is connected with the valving member mounted in the line for supplying liquid to the batcher.

EFFECT: enhanced precision.

Description

The invention relates to the field of dispensing liquid media, for example, in bottles, cans, etc. and can be used in various fields of technology.

Liquid dispensers are known, for example, according to AC 1337670, RF patent 2161590, containing filling devices, vessels with a constant liquid level, locking elements, vacuum sources, etc., in which the liquid is poured directly into containers (bottles, cans, etc.).

The device according to patent 2081815 (prototype) has a consumable container with liquid, a sealed chamber with a folding bottom and a vacuum line.

The disadvantages of the known device: 1) the need to maintain a constant liquid level in the supply tank, which requires the presence of additional devices; 2) the need for a vacuum source and a vacuum line; 3) the complexity of the device itself and the procedures for working with this device.

The technical result is to simplify the design as a whole, eliminating dosing errors.

The technical result is achieved by the fact that the liquid dispenser in level, containing a pouring head, an air tube, a shut-off element on the liquid supply line to the dispenser, a container availability sensor, a control device, is additionally equipped with a liquid supply pipe into the container, an air pressure sensor in the container, a pressure sensor liquid at the inlet to the dispenser and an additional air tube, and the tube for supplying liquid to the container is located inside the filling head and is in communication with the line for supplying liquid to the dispenser, an additional air tube located concentrically on the bottom of the main air tube, the air pressure sensor in the container is in communication with the airspace of the container, and the sensors for the presence of packaging, liquid pressure at the inlet of the dispenser and air pressure in the container are connected with a control device, and the latter with a shut-off element on the supply line liquid into the dispenser, while the tube for supplying liquid to the container is placed in the filling head so that an air space is formed between the tube and the inner surface of the neck of the container, and an additional air tube It executes with the possibility of movement relative to the primary air tube.

The device shown in the drawing. The device comprises a casting head 1 placed on the neck of the container 2, a liquid supply line 3 with a locking member 4, an air tube 5 and a liquid supply pipe 6, air pressure sensors in the bottle 8, liquid pressure at the inlet to the dispenser 9 and the presence of the container 10, which controls device (UU) 11, additional air tube 12.

The device operates as follows: in the initial position, the locking element 4 is closed. After supplying the container 2 for filling, it is placed at the bottom of the casting head and the container rim is sealed with an elastic element located in the head by mutual movement of the head and / or container. In this case, the sensor for the presence of containers 10 is activated and UU 11 opens the locking element 4. The liquid from line 3 enters the head and through the tube 6 to the container. Air from the container is removed through tubes 5 and 12. When the liquid level in the container reaches the lower edge of the tube 12, the air outlet is blocked, and air pressure is generated in the container above the liquid level, caused by the pressure of the liquid at the inlet to the dispenser. A pressure jump occurs in the cavity 7 of the head, the pressure sensor 8 is triggered, the signal from it enters the UU 11, and it gives a signal to close the organ 4. The required dose is dialed. When the next container is supplied to the dispenser, the cycle of the device is repeated.

The advantages of the device are determined by the fact that: 1) in the proposed device there are no moving parts in the casting head, it is simple to manufacture and reliable, because consists of one hard element; 2) the specified level of liquid filling in the container can vary within wide limits; 3) dosing error due to changes in fluid pressure at the inlet to the dispenser is eliminated.

Claims (3)
