We produce washers (rinsers) for jars, bottles and cans. The devices are designed for washing and drying packages in the production lines of agri-food processing, fruit and vegetable industry, meat, poultry, fish, food concentrates and others.
The packages, after entering the washer, are transported by the plate chain of the input conveyor, and then collected by the gripper conveyor system. Packages held by gripper chains are carried over nozzles installed in the lower part of the device, to which water and air are supplied. As soon as each package is within the reach of the nozzles, the rinsing or blowing process takes place (depending on which nozzles are working). The package is positioned so that the nozzles are directed towards the inside of the package. After passing through the area with the nozzles, the packages (still held by the gripper chains) are transferred to the exit plate chain conveyor, which feeds the packages to the next element of the line. The washer operation depends on the signals coming from the line devices cooperating with the washer.
The packages transported by the plate chain, after entering the washer, are picked up (perpendicular to the direction of movement) by a rotating (clockwise) ring with swords. Swords locate the packages around the circumference of the ring. There are nozzles under the ring to which water and air are supplied. When the packaging rotating with the ring is within the reach of the nozzles, the rinsing or blowing process takes place (depending on which nozzles are working). The package is then positioned such that the nozzles are directed towards the inside of the package. The ring is driven by a system of rollers which are driven by a gear motor through chain gears. The linear speeds of the transporting chain of the line conveyor and the rotational speed of the ring are selected so as to ensure a smooth transition of packages from the conveyor to the ring and vice versa. In order to fully protect this process, inductive sensors were installed on the conveyor, before the entrance to the washer and after the exit from it, which immobilize the washer ring in the event of disruptions in the supply or collection of packages from the washer. Additionally, in order to fully synchronize the above-mentioned speed, the washer ring speed is regulated.
