The machine shown in Figure 1 is designed to automatically trim part of an automobile door seal extrusion away and leave the desired part intact. Both ends of an extrusion are trimmed and then the ends of the extrusion are bonded together to make the complete door seal.
Figure 2 shows a closer view of the operator interface and the guide holes through which the extrusion is drawn. As the operator places the extrusion into the guide holes, sensors detect the extrusion and start the drive mechanism. Each end of the extrusion is trimmed independently as it is positioned and drawn into the machine. Sensors detect when the proper length of extrusion edge is trimmed and severed from the base extrusion. The severed part is dropped into the scrap bin and the rest of the extrusion is pushed back out of the machine. All sequences and operations of the machine are controlled by a PLC controller. The speed of the extrusion as it is drawn into the machine and the speed with which it is pushed out is controlled from the front panel. The length of cut is controlled by the position of sensors that detect the length of the extrusion. For safety purposes, the machine will not operate when access doors are open.
This machine is equipped with an operator light and a fan to help the operator stay cool. The machine is mounted on castors and with adjustable feet to stabilize the machine when it is properly positioned.
