  • Figure 7 shows an example of a state of the art carrier or bin configuration where a component tape holders or reel 103 may be positioned on two rollers 101 and 102, both arranged on roller shafts.
  • the front roller 101 is positioned horizontally out from the centre of the shaft of the component reel in order to prevent the component tape holders or reel from moving when applying a traction force F to the component tape 104, e.g. by pulling the tape.
  • the front roller 101 exerts a frictional force u*N1 against the reel 103 due to the counteracting force N1 , i.e. counteracting the traction force.
  • the front roller constitutes a mechanical stop for blocking a movement of the component tape holders or reel in the traction force direction, thereby enabling and facilitating a spinning or rotational movement of the tape reel, i.e. feeding of the component tape.
  • the reel instead only begins to spin.
  • the second roller 102 exerts a frictional force u*N2 due to the counteracting force N2, i.e. counteracting the gravity force mg.
  • the reel may, in addition to the spinning or rotational movement, begin to momentarily lift from the lower roll 102 in an uncontrolled manner thereby causing an unwanted jumpy behavior. Because the small amount of tape left on the reel reduces the gravity force mg acting on the reel, the gravity force acting on the reel becomes too small relative to the traction force F resulting in a rolling movement against the front roller 101 , thereby lifting the reel from the lower roller 102. Thus, instead of an intended spinning movement, the reel 103 is lifted or elevated from its spinning or resting position, i.e. when the reel is supported by the lower roll 102.
  • the rolling movement against the front roller 101 may generate a quick increase of the traction force thereby causing a temporarily and quick build-up of component tape tension which, in turn, causes the tape to be pulled backwards when the reel resumes its position on the lower roll 102.
  • This effect may coincidence with the release of the tape feeding pins 43 causing the tape to slip backwards in the feeder.
  • the fed component tape may accidentally be withdrawn which, in turn, could cause a malfunction in the feeding of the subsequent component since the following compartment may be empty during the subsequent feeding step of feeding a component to its pick-up position.
