  • the first bypass guide rait coupling member 120 further includes a threaded engagement cap 120 ⁇ and in this embodiment, the engagement cap 120i is made of zinc alloy having a number of engagement fingers 120j. As shown in Figure 4, there are four engagement fingers 120j which are slightly arcuate, spaced apart (with the spaces aligned with the ridges 120f) and arranged in a ring to form a generally cylindrical shape. Each of the engagement fingers 120J is adapted to engage with corresponding engagement surfaces 120f of the attachment member 120b so that the engagement cap 120i sits over and on the head portion 120d.

  • the rotation of the tightening screw 120k draws the threaded engagement cap 1201 further inwards towards the attachment member 120b and causes the engagement surfaces 120f to spread the respective engagement fingers 120] of the engagement cap 1201 further apart to enlarge or increase the diameter of the engagement fingers 120i slightly to engage the first bypass guide rail's internal surface 112c.
  • the first bypass guide rail is fixedly (and removably) and securely attached to the first vertical support member 108 and also to the first support frame 104.

  • the first bypass guide rail 112 has a generally full cylindrical shape after the half cylinder section 112a and in particular when the bypass guide rail 112a travels to the next work station 200. Further, the first bypass guide rail 112 similarly includes a first bypass free-movement section 112d which is inclined to allow the hanger 2000 to move or roil by gravity to its destination. As the name implies, the first bypass guide raii 112 is intended to bypass the main guide rail 1012 which is used mainly by the workers if no line rebalancing is needed.
  • the main guide rail 1012 includes a first step section 1012a to form a first holding section 1012b immediately before the first step section 1012a which is located in close proximity to where the worker sits in order for the worker to easily retrieve any hangers 2000 from the first holding section 1012a.

  • the main guide rail 1012 runs and gradually reduces in gradient from the first work station 100 to the second work stations 200 and Figure 5 illustrates the second work station 200. It can be appreciated that the main guide rail 1012 continues and forms a second step section 1012e at the second work station 200. Similar parts of the second work station 200 use similar reference numerals as the first work station 100 except that the numerals start with "2" to be consistent with the reference numeral for the second work station 200.

  • pivoting mechanism 504 is slightly bigger than the connector 502 so that when the connector 502 is inserted into the first bypass guide rail 112, the diameter and profile of the first bypass guide raii 112 is substantially flushed with the diameter and profile of the pivoting mechanism 504.
  • the pivoting arm 504e includes an attachment portion 504i for connecting to the traversing bridge 506.
  • the traversing bridge 506 has a bridge connector 506a for connecting to the attachment portion 5041 of the pivoting arm 504e and a half cylinder bridge section 506b to reduce the profile of the traversing bridge 508 to enable the hanger 2000 along the first bypass guide rail 112 to cross smoothly to the main guide rail 1012.
  • the pivoting arm 504e also includes a tapered section 504j to allow a gradual transition to the traversing bridge 506.

  • a force is needed to deflect the traversing bridge 506 to an "open" position and when the force is removed, the bearing 504d allows the switch 500 (i.e. the traversing bridge 506) to drop back to the first position under gravity.
  • the switch 500 may inciude a biasing spring (not shown) which biases the traversing bridge 506 from the second position to the first position.
  • the hanger 2000 would not arrive at the second holding section 1012f of the second work station 200 and instead, the hanger 2000 bypasses this in view of the arrangement of the first bypass guide rail 112 and travels to the second station first switch 500 and rolls along the traversing bridge 506 and drops onto the main guide rail 1012 and travels along the second free-moving section 1012h of the second work station 200 to arrive at a third holding section (not shown but similar to the second holding section 1012f of the second station 200) of the third work station 300. In this way, the hanger 2000 bypasses the second work station 200 to arrive at the third work station 300 which may be used to balance the production line.
  • FIG. 8 and 9 illustrate a first position DD of the hanger 2000 when the hanger 2000 is roiling along the traversing bridge 506b and a second position EE when the hanger 2000 has "dropped" (see step arrow FF of Figure 8) onto the main guide rail 1012.
  • the second bypass guide rail 114 and the third bypass guide rail 116 of the first work station 100 works in a similar manner and from Figure 5, it can be appreciated that the second bypass guide rail 114 includes a second station second switch 600 at its end, and the third bypass guide rail 116 includes a second station third switch 700 at its end.
  • the second station second and third switches 600,700 are similar in construction and structure as the second station first switch 500. if the worker at the first work station 100 places the hanger 2000 at the second bypass guide raii 114, the hanger 2000 would travel along the second bypass guide rail 114 and onto the second station second switch 600 before crossing over to the first bypass guide rail 212 at the second work station 200. This would mean that the hanger 2000 would bypass the third work station 300 and cross over from the first bypass guide rail 212 of the second work station 200 to the main guide rail 1012 at the third work station to reach a fourth holding section (not shown but similar to the second hoiding section 1012f of the second work station) of the fourth work station for the garment attached to the hanger 2000 to be worked on by a worker at the fourth station,
  • the hanger 2000 if placed at the third bypass guide rail 116 at the first work station would bypass three work stations and arrive at a fifth work station along the production line.
  • a worker at the second work station may similarly bypass downstream work stations 200,300... by placing hangers 2000 at the first, second or third bypass guide rails 212,214,216 at the second work station 200.
  • the separation distance between the guide rails and the traversing bridge 506b needs to be relatively small of about a few millimeters, and preferably up to 1cm. This explains why it Is preferred for the traversing bridge 506 to have the half cylinder bridge section 506b to reduce the profile of the traversing bridge 506 to faciiitate a much smoother crossing of the hanger 2000. This also means that the apparatus 1000 needs to allow hangers 2000 to travel smoothly when the hangers 2000 are not travelling on the traversing bridge 506b for example.
  • the hanger 2000 needs to push open the second station first switch 500 as the hanger 2000 travels along the second free-movement section 1012h of the main guide rail 1012 to the third work station 300.
