Marking system for springs

1. A marking system for springs comprising:

a conveyor;

an arranging apparatus for arranging a spring fed to the arranging apparatus by the conveyor, wherein the arranging apparatus comprises: an arranging unit base; a first arranging jig fixed to the arranging unit base to contact one surface of the spring; a second arranging jig located at a site facing the first fixing jig and contacting an surface opposite to the surface of the spring that contacts the first arranging jig; a rotary motor connected to the second arranging jig, for rotating the second arranging jig; an arranging unit moving unit to which the second arranging jig is fixed and configured to move forwards and rearwards towards the spring; an arranging unit moving shaft passing through the arranging unit moving unit; and an arranging unit cylinder connected to the arranging unit moving unit, for moving the arranging unit moving unit forwards and rearwards; and

a marking apparatus for applying an identification mark on the arranged spring fed to the marking apparatus by the conveyor,

wherein the marking apparatus comprises:

a frame having a space for marking therein;

a pad unit for applying a mark on the arranged spring located in the frame; and

an ink unit for supplying ink to the pad unit.

2. The marking system of claim 1 , wherein the pad unit comprises:

a pad for applying a mark on the arranged spring;

a pad feeding unit to which the pad is connected, for moving the pad upwards and downwards, and forwards and rearwards;

a pad unit cylinder to which the pad is connected, for providing power for moving the pad upwards and downwards; and

a rodless cylinder connected to the pad feeding unit, for providing power for moving the pad forwards and rearwards.

3. The marking system of claim 1 , wherein the ink unit comprises:

an ink cup base;

an ink cup for supplying ink;

a marking plate to which the ink contained in the ink cup is stuck;

a marking plate feeding unit for positioning the marking plate and moving the marking plate forwards and rearwards on a lower side of the ink cup; and

a marking unit cylinder for providing power for moving the marking plate feeding unit forwards and rearwards.

4. The marking system of claim 1 , wherein an escape part contacting an end of the spring where the rotation of the spring is completely ended is formed in the second arranging jig, and the spring is rotated by bringing the escape part and the end of the spring into contact with each other through rotation of the second arranging jig.

5. The marking system of claim 1 , wherein a protrusion contacting a start part of the spring where the spring starts to be rotated is formed in the first arranging jig, and a location of the spring is arranged by bringing the protrusion and the start part of the spring into contact with each other through rotation of the spring.
