Abstract

A washer dispensing system includes a retaining bin that is configured to receive washers within a washer-retaining chamber. The retaining bin includes a bin outlet connected to the washer-retaining chamber. A vibration motor is coupled to the retaining bin. The vibration motor is configured to vibrate at least a portion of the retaining bin to move the washers towards the bin outlet. A discharge chute is coupled to the retaining bin. The discharge chute includes a washer delivery channel connected to the bin outlet.

First claim

What is claimed is:

1. A washer dispensing system, comprising:
a retaining bin that is configured to receive washers within a washer-retaining chamber, the retaining bin comprising a bin outlet connected to the washer-retaining chamber;
a vibration motor coupled to the retaining bin, the vibration motor being configured to vibrate at least a portion of the retaining bin to move the washers towards the bin outlet; and
a discharge chute coupled to the retaining bin, the discharge chute comprising:
a washer delivery channel connected to the bin outlet; and
a recessed opening proximate to a delivery end, wherein the discharge chute is configured to stop at least one of the washers at the delivery end over the recessed opening such that a central hole of the at least one washer is positioned over the recessed opening.

2. The washer dispensing system of claim 1 , wherein the retaining bin further comprises lead-in walls that inwardly angle towards the bin outlet, wherein the lead-in walls are configured to direct the washers towards the bin outlet.

3. The washer dispensing system of claim 1 , wherein the bin outlet is sized and shaped to receive only one of the washers at one time.

4. The washer dispensing system of claim 1 , wherein the bin outlet has a width and a height that are slightly larger than a diameter and a thickness of a plurality of the washers.

5. The washer dispensing system of claim 1 , wherein the discharge chute further comprises a bed and opposed side rails, wherein the washer delivery channel is defined between the bed and the side rails.

6. The washer dispensing system of claim 1 , wherein the discharge chute further comprises one or more slots formed in one or more side rails proximate to a delivery end, wherein the one or more slots are configured to retain portions of resilient stops that are configured to extend into a washer delivery channel to stop one or more of the washers.

7. The washer dispensing system of claim 1 , wherein a base of the retaining bin is downwardly angled towards the bin outlet to allow gravity to draw the washers towards the bin outlet.

8. The washer dispensing system of claim 1 , further comprising a mounting flange that downwardly angles a base of the retaining bin towards the bin outlet to allow gravity to draw the washer towards the bin outlet.

9. The washer dispensing system of claim 1 , further comprising one or more resilient stops proximate to a delivery end of the discharge chute.

10. The washer dispensing system of claim 9 , wherein the one or more resilient stops comprise an anchor retained within a portion of the discharge chute, and a spring extending into the washer delivery channel.

11. A washer dispensing method, comprising:
coupling a vibration motor to a retaining bin including a washer-retaining chamber connected to a bin outlet;
coupling the retaining bin to a discharge chute including a washer delivery channel connected to the bin outlet;
receiving washers within the washer-retaining chamber of the retaining bin;
operating the vibration motor to vibrate at least a portion of the retaining bin to move at least one of the washers towards and into the bin outlet;
moving the at least one of the washers into the washer delivery channel from the bin outlet; and
stopping at least one of the washers over a recessed opening proximate to a delivery end of the discharge chute.

12. The washer dispensing method of claim 11 , further comprising directing the washers towards the bin outlet with lead-in walls that inwardly angle towards the bin outlet.

13. The washer dispensing method of claim 11 , wherein the bin outlet is sized and shaped to receive only one of the washers at one time.

14. The washer dispensing method of claim 11 , further comprising retaining portions of resilient stops in one or more slots formed in one or more side rails proximate to a delivery end of the discharge chute.

15. The washer dispensing method of claim 11 , further comprising downwardly angling a base of the retaining bin towards the bin outlet to allow gravity to draw the washers towards the bin outlet.

16. The washer dispensing method of claim 11 , further comprising securing one or more resilient stops proximate to a delivery end of the discharge chute.

17. The washer dispensing method of claim 11 , further comprising retaining an anchor of a resilient stop within a portion of the discharge chute, and extending a spring of the resilient stop into the washer delivery channel.

18. A washer dispensing system, comprising:
a retaining bin that is configured to receive washers within a washer-retaining chamber, the retaining bin comprising a bin outlet connected to the washer-retaining chamber, and lead-in walls that inwardly angle towards the bin outlet, wherein the bin outlet is sized and shaped to receive only one of the washers at one time, wherein the lead-in walls are configured to direct the washers towards the bin outlet, wherein a base of the retaining bin is downwardly angled towards the bin outlet to allow gravity to draw the washers towards the bin outlet;
a vibration motor coupled to the retaining bin, the vibration motor being configured to vibrate at least a portion of the retaining bin to move the washers towards the bin outlet;
a discharge chute coupled to the retaining bin, the discharge chute including a bed and opposed side rails that define a washer delivery channel that is connected to the bin outlet, and a recessed opening proximate to a delivery end, wherein the discharge chute is configured to stop at least one of the washers at the delivery end over the recessed opening; and
one or more resilient stops that extend into the washer delivery channel proximate to the recessed opening, wherein the one or more resilient stop are configured to stop one or more of the washers.

19. A washer dispensing system, comprising:
a retaining bin that is configured to receive washers within a washer-retaining chamber, the retaining bin comprising a bin outlet connected to the washer-retaining chamber;
a mounting flange that downwardly angles a base of the retaining bin towards the bin outlet to allow gravity to draw the washer towards the bin outlet;
a vibration motor coupled to the retaining bin, the vibration motor being configured to vibrate at least a portion of the retaining bin to move the washers towards the bin outlet; and
a discharge chute coupled to the retaining bin, the discharge chute including a washer delivery channel connected to the bin outlet.

20. A washer dispensing system, comprising:
a retaining bin that is configured to receive washers within a washer-retaining chamber, the retaining bin comprising a bin outlet connected to the washer-retaining chamber;
a vibration motor coupled to the retaining bin, the vibration motor being configured to vibrate at least a portion of the retaining bin to move the washers towards the bin outlet;
a discharge chute coupled to the retaining bin, the discharge chute including a washer delivery channel connected to the bin outlet; and
one or more resilient stops proximate to a delivery end of the discharge chute.

21. The washer dispensing system of claim 20 , wherein the one or more resilient stops comprise an anchor retained within a portion of the discharge chute, and a spring extending into the washer delivery channel.

22. A washer dispensing method, comprising:
coupling a vibration motor to a retaining bin including a washer-retaining chamber connected to a bin outl
