MRC-II-1200-E

The MRC-II-1200-E dual lane post repair system is designed for round ends with diameters from 52.5 mm (202) to 99 mm (401). (Other sizes on demand). The lacquer is applied in a spray station and it is dried in a convective tower oven. The conveyor speed is adjustable from 100 up to 600 ends per minute en each lane therefore achieving the two lanes a combined production of 1200 ends per minute. Its design allows differences in size installation in each lane. Also it is allowed to keep one lane working and other lane stopped. Working at different speeds in the lanes is also possible.
By means of the downstackers that have a turned end and low level detector installed, the ends are driven to the spray station. There, a dual rotating head fitted with Peñalver pneumatic airless spray guns apply the lacquer in only one pass. The dual rotary head gun speed is adjustable and assures the accurate spray on the score line. The new dual rotary head lets you, choosing the suitable nozzle, cover also the rivet or all the end's surface. This is possible using solid tungsten carbaid seals designed specially for this application.

The dog chains convey the end with a forward and stop movement, right into the spray station stop, where the guns spray the score and optionally the rivet (by a wider spray pattern). The spray guns have a seat for interchangeable nozzles, which are available for different flows and patterns.

The vertical oven completely integrated in the compact unit design provides the necessary temperature and time to achieve the lacquer curing. The oven incorporates a cooling chamber to decrease the temperature at the oven exit.

The heating and cooling are produced by convection inside the oven, for this purpose the oven has ventilation turbines and a fume outlet. The oven is supplied with electric heaters or a gas burner (100mbar or 1bar) depending on the customer's preferences. By construction and design jams and end damages are nearly impossible. Fans in the oven are equiped with security systems to assure that the flows are correct and an accumulation of gases fail will never occure. A VOC level monitor always advises if the % in the oven begins to be dangerous.

The unit includes an electrical cabinet and lacquer equipment (own or shared). The PLC and control system are located in the electrical cabinet, on which the temperature and revolution gauges are visible. In the lacquer cabinet is installed a security system to behave so that leakages do not appear on the hoses. All the electric components installed are explosion proof and ATEX certified.

On the unit, a button and synoptic panel show the alarms and other relevant information. The lacquer system includes a pump and other devices such as filters and regulators for the required application within the established parameters. The desired amount of lacquer per end can be achieved (within a range) by modifying the pump pressure and installed nozzle (different flow).

The Peñalver machines incorporate a semimanual grease system and automatic oiling system, reducing drastically the maintenance time and increasing the machine's lifetime. Also the unit includes a pneumatic system for the automatic tensing oven chain, ends feeding and opening and closing of the oven's front bottom doors. Due to its configuration, the machines are easy to install and to join adjacent processes, such as conversion presses, automatic bagging stations, etc.

Features

- Concentric gun head based on a rotary union allowing a speed per line of 600 epm with combined speed of 1200 epm.

- Allows different end sizes per lane and independent speeds (max. 600 epm per lane).

- Each lane runs independently achieving therefore a higher efficency.
