Carrier for holding a plurality of multi-receptacle units
A system and method provides a supply of consumables to a processing instrument that uses one or more of the consumables for each of a plurality of processes performed by the instrument. The system includes a loading drawer holding a carrier for receiving a plurality of consumables and an input module for holding a carrier supporting a plurality of consumables thereon and presenting the consumables for access by the instrument. A transporter includes a vertical elevator and a lateral actuator for moving a lift platform vertically and laterally and for transporting carriers on the lift platform with or without consumables supported thereon between the loading drawer and the input module, between the loading drawer and one or more holding shelves, or between the input module and one or more holding shelves. A carrier includes parallel support rails for holding multiple receptacle units and retainer tabs for retaining the units on the support rails.
1. A carrier for holding a plurality of multi-receptacle units, each multi-receptacle unit including a plurality of receptacles connected to each other in a side-by-side arrangement, wherein the carrier comprises:
a pair of parallel support rails for slidably supporting the multi-receptacle units thereon with at least one of the receptacles of each multi-receptacle unit disposed between the support rails, and
a resilient tab associated with each support rail, wherein the resilient tabs are configured to be laterally flexible between first positions at which the resilient tabs will be contacted by a multi-receptacle unit supported on the support rails to prevent the multi-receptacle unit from sliding off the ends of the support rails and second positions at which the multi-receptacle unit supported on the support rails is not prevented from sliding off the ends of the support rails.
2. The carrier of claim 1 , wherein each resilient tab is disposed at the end of a serpentine spring.
3. The carrier of claim 2 , wherein each serpentine spring is an integral portion of each associated support rail.
4. The carrier of claim 1 , wherein the support rails are made from spring steel.
5. The carrier of claim 1 , further comprising a carrier base comprising a first end, a second end, and a connecting portion extending between the first end and the second end, wherein the connecting portion is generally narrower than the first and second ends.
6. The carrier of claim 5 , wherein the support rails are attached to opposed edges of the connecting portion.
7. The carrier of claim 1 , further comprising a carrier base with one or more locator holes formed in the bottom of the carrier base.
8. The carrier of claim 7 , comprising one locator hole at a first end of the carrier base and a locator slot at a second end of the carrier base.
9. The carrier of claim 8 , comprising two locator holes at the first end of the carrier base and two locator slots at the second end of the carrier base.
10. The carrier of claim 7 , comprising two locator holes at a first end of the carrier base and two locator slots at a second end of the carrier base.
11. The carrier of claim 1 , wherein the resilient tabs are bent laterally inward or laterally outward to be contacted by the multi-receptacle unit supported on the support rails when the resilient tabs are in their respective first positions.
12. The carrier of claim 1 , further comprising at least one multi-receptacle unit including a plurality of receptacles connected to each other in a side-by-side arrangement, wherein the multi-receptacle unit is slidably supported on the pair of support rails with at least one of the receptacles disposed between the support rails.
13. The carrier of claim 12 , wherein at least one of the receptacles of the multi-receptacle unit is disposed on either side of the support rails.
