Pneumatic bottler for chemical products, especially paints and varnishes

The subject of the invention is a pneumatic filler for chemical products, especially paints and varnishes.

The previously used design solution for the drive of the bottling machine elements, i.e. the dosing piston, the chain with drivers and the valve control unit, consisted in transferring the power from the electric motor to individual elements by means of a gear, cam system and connecting rods. Filling machines in which the electric motor has been removed, introducing a set of pneumatic actuators in its place are also known. This solution, however, has major drawbacks in the form of difficulties in synchronizing the movements of pneumatic actuators driving the dispenser and the chain moving the package. The inability to achieve a smooth chain movement causes the product to splash out of filled but not yet closed cans. This disadvantage was partially overcome by reducing the speed of operation of the individual actuators, which, however, significantly reduced the efficiency.

An object of the invention is to increase the speed of the endless chain with drivers and to eliminate product spill from filled but not yet closed cans.

In the pourer according to the invention, the piston rod of the dosing cylinder is located under the spreader table in the axis of the endless chain with drivers and is connected to the actuator and has a vertical chain driver. The vertical chain driver is bounded on both sides by guide bars and ends at the top with a movable lever that overlaps the endless chain driver on the pushing direction side.

The movement of the actuator driving the dosing piston and the coupled endless chain drive with drivers is hydraulically damped, thereby achieving a constant speed of the endless chain with the drivers moving the filled cans across the bottler table. The constant speed makes it possible to move the filler of the filled, not closed, cans across the table without splashing the product contained in them. Also, the association of the dosing plunger movements with the endless chain with the drivers makes it impossible to repeat the dosing of the liquid to the previously filled can.

The subject of the invention is shown in an exemplary embodiment in the drawing, which shows schematically the pourer.

The bottler consists of an endless chain with drivers 3, the upper strand of which is above the surface of the bottler table. Under the surface of the spreader table, in the axis of the endless chain with drivers 3, there is a dosing cylinder 9 whose piston rod is connected to the cylinder 7 and has a vertical chain driver 4. The vertical chain driver 4 is limited on two sides by guide bars and ends at the top with a movable overlapping lever one end on the chain driver 3 from the side of the pushing direction. The paint hopper 1 is located above the bottler table and is connected by a conduit via a three-way dosing valve 11 to the dosing cylinder 9, and the output from this cylinder via a three-way dosing valve 11 is connected to the nozzle 2. The three-way dosing valve 11 is linked by a linkage to the actuator 10. The actuator 10 is connected by a conduit 6 with an impulse valve 8 controlled by a button of a lever that moves the can on the table surface and with a manifold 18. A double-acting actuator 7 is connected by conduits 17 through throttle valves 16 with a two-position three-way manifold 18 pneumatically controlled impulse valves 13,14 powered by a line 6 in front of the distributor 18. Additionally, the position of the impulse valve 13 is regulated by the dosing regulator knob 12. Above the spreader table in the can axis, behind the filler there is a pneumatic lid closing machine 5 connected by a conduit 6 through an impulse valve with a broken lever 15 with the supply line to the distributor 18. The distributor 18 is supplied with compressed air from the network through the air filter 23, the reducer 22, the air lubricator 21, the shut-off valve 20 and the spool valve 19.

The size of the dose is regulated by the dosing regulator 12 impulse valve 13. The frequency of actuator strokes, and thus the capacity of the bottler, is changed by throttles 16. The filled can is closed with a lid closing machine 5 controlled by an impulse valve with a broken lever 15. The filling machine has a safety device before dosing the paint in the absence of packaging under the nozzle 2 in the form of an impulse valve 8 controlled by a lever moved by the can moved under the nozzle.
