Ejection module is the last mechanism in KOMBIS TMM8003. It is designed to eject the ready tube from machine.
The position consists of transportation tape, optical sensor, clamp with a gripper and linear axis. When the tube ready with winded cap stays in front of this position the clamps of the mandrel open, an air enters in the cavity of the mandrel which blows out the tube, the gripper holds it and lets the tape through. The sensor reads the tube passed through. If this does not happen the clamp for pulling out of the tube without a cap is put into action. It presents a pneumatic clamp fastened for a pneumatic cylinder. As soon as the clamp clasps the tube the pneumatic cylinder is put into action and draws out the tube. If this does not happen the machine stops.
The ejection module has some basic mechanisms: Transporter Digital fiber sensor Clamp with a gripper Linear axis Pushing mechanism The transporter is drive by Three phase Asynchronous Motor. The Linear axis by servo motor. Their drivers are in Electrical cabinet in front of Tube making module.(see page 10)
Transporter Fiber head Clamp with a gripper Linear axis Servo motor Asynchrony motor Pushing mechanism Digital Fiber Sensor
The Fiber head of Digital fiber sensor is mounted under the mandrel. The sensor is on the outside profile (near the doors). His function is to check for blowing tube. In the previous position have a sensor which check for cap. When the tube is blow out the clamp just underlay it until blowing. When the tube hasn’t cap, the gripper opens and eject it from mandrel. The sensor The Fiber Head
1 2 1. Change the clamps on gripper. You can do this as unscrew the bolts on two clamps. 2. Unscrew the bolts from both side and move profiles how wide or narrow how necessary. 3 3 4 5 6 Be sure POWER SUPPLY and AIR SUPPLY are SWITCH OFF !!!
3. Do same with other holders 4. Move long profiles inward or outward in depending of tube size. The tubes must move on transporter between profiles free. 5. Put on the tube on the transporter belt under the cover and check the sensor. He must light when have a tube in front of it. If he isn’t light, move the sensor up or down, or tune it sense by potentiometer in the rear side of the sensor. potentiometer
6. Move forward by hand the table on Linear axis until the clamps on the gripper touch the tube’s cap (on the mandrel). 9. First sensor 7. When we are sure that this is right position, we must move back the table 20÷30 mm and tune the middle sensor until he light. 8. Unscrew the tube’s cap (on the mandrel), open clamps on gripper and move forward by hand until we are sure that by closing the clamps will catch shoulder. 9.Tune the first sensor until he light. 6 7. Middle sensor 8
10. Move backward by hand the table on Linear axis until second sensor start lighting. (As a rule this sensor is factory tuning) 11. When we are sure that the second sensor is lighting, we must check for collision between clamps and profiles. 11. Check Position 12. Switch on power supply and air supply and in “STEP mode” check the three positions. 10. Second sensor
Irregularity CauseWay of removing 1. The machine stopped work, because the tube is not eject 1.1 The Digital Fiber Sensor light constantly. 1.2 The gripper with clamps can not catch the tube’s shoulder (when there isn’t cap). 1.3 The tube is not blow from mandrel (when there is cap). 1.4 The Linear axis not move. There is Alarm of the servo drivers. 1.5 The belt is broken. 1.1Check the sensor. If it is necessary adjust it (see passport 10.Sensors). 1.2 Switch off power and air supply, open the clamps and move by hand gripper in front position until reach shoulder, close clamps. If it is necessary adjust the first magnetic sensor (see page 13) 1.3 Check for air supply on index table. 1.4 See application with servo driver alarms to know how to correct it. \\A15fs1\groups\ Конструктивен Отдел \Training\Applications\Servo SGDH Alarms.pdf 1.5 Switch off power and air supply and change the broken belt.
Irregularity CauseWay of removing 2. Tubes not move on transporter 2.1 The lateral profiles are not on necessary distance. 2.2 The belt is broken. 2.3 The belt not turn. There is Alarm of the frequency inverter. 2. 1 Do step 2 and 3 from page 11 and 12. 2.2 Switch off power and air supply and change the broken belt. 2.3 See application with inverter alarms to know how to correct it. \\A15fs1\groups\ Конструктивен Отдел \Training\Applications\Inverter J1000 Alarms.pdf 3. The tubes are not push from belt. 3.1 The pneumatic cylinder not move. 3.2 Optical sensor can not “see” tube 3.1.1 Check for air supply. 3.1.2 Switch off air supply then move the cylinder by hand. If it is defective change it. 3.2 Do step 5 from page 12
