Oil Filter Assembly Line

Machine No. 6318

This machine assembles Inner Elements used in oil filters. Pleat Packs are conveyor fed laying flat from the curing oven to a diverter which rotates them on edge and splits them into 2 tracks. Packs are compressed 2 up into forming dies and pressed down into forming fixtures on a 16 station cam driven index table. Formed packs are pressed down 2 up through gluing fixtures into curing fixtures on a 2nd 16 station cam driven index table. As the packs are pressed down through the gluing fixtures, dual glue heads position and apply glue 2 up through window ports in the gluing fixtures to the pack ends, seaming the packs into the cylindrical form. Seamed cylindrical pack elements are pressed down 2 up through the curing fixtures into fixtures on a 3rd 16 station cam driven index table. Center Tubes are hopper and bowl fed through a dual inline feeder track to a dead track.

Tubes are picked up and rotated 90 degrees and placed 2 up onto lower rams which have been raised up through the center of the seamed pack elements. Upper rams lower engaging the top of the center tubes then forces both rams and center tubes down, placing the center tube in the desired position inside of the seamed pack elements. Seamed Pleat Pack Elements with Center Tubes are pushed 2 up down into jaws on a dual part fixture on a 52 position cam driven indexed carousel. First End Caps are hopper and bowl fed through a dual track where they are rejected if bad otherwise they are filled with a measured amount of Plastisol Epoxy and placed under the Seamed Pleat Pack Elements with Center Tubes. The First End Caps are pressed onto the Seamed Pleat Pack Elements with Center Tubes and transverse across Induction Heaters to cure the Plastisol. The fixtures are rotated 180 degrees and the Second End Caps are placed and epoxied onto the Seamed Pleat Pack Elements in the same manner as the First End Caps. Completed Inner Element assemblies are offloaded onto a conveyor for further conveyance down the production line. Reject assemblies are offloaded into a reject chute.

CONTROLS – The control system uses an Allen Bradley PLC5  running a ladder logic program to control the real time sequencing of the machine.  Operator interface, data logging and any other interface to high-level devices are provided by a custom Microsoft Visual Basic program running on an Intel-powered PC using Windows NT Workstation 4.0 as the operating system.  The control system provides the following standard features as well as many others:

· Machine Status display and messages for any machine fault stops.
· Storing, loading, and editing operational parameters, by customer part number.
· Operational Mode selection.
· Production data accumulation by Year, Week, Day, Hour and Lot.
· Manual control of each output and status monitoring for each input for every station.
