treadmill/moving platform - moving Objects by colliding on a platform to the direction of the platform

Hello.

I'm new to game dev and unity maybe that is why this is so hard for me.

I'm trying to build a moving platform in 3D similar to the treadmill concept but for a factory.

my current code, move the items that Hit the platform to the right of the (ITEM) not the platform .. I know that because when i rotate the "item" or change it's direction, it starts moving in a different direction than that of the platform's

void OnCollisionStay(Collision collision) { collision.collider.transform.Translate(this.transform.right * Time.deltaTime); }

---

this code is on the platform that is supposed to move the collided objects to the X axis of the platform that is not what is happening, it moves the "items" ( collided objects ) to the collided objects's X-axis so it's currently moving based on the collider's direction no the platform.

it seems to be quite simple, could anyone help?
