Abstract

A conveying system includes a conveyor for moving items along a primary conveyance path. A first buffer table is releasably connected at a first lateral side of the conveyor, and a second buffer table is releasably connected at a second lateral side of the conveyor.

Claims

1. A conveying system, comprising:

a conveyor for moving items along a primary conveyance path;

a first buffer table releasably connected at a first lateral side of the conveyor;

a second buffer table releasably connected at a second lateral side of the conveyor;

a first latch arrangement releasably engaging the first buffer table with the first lateral side of the conveyor; and

a second latch arrangement releasably engaging the second buffer table with the second lateral side of the conveyor.

2. The conveying system of claim 1 wherein:

the first latch arrangement includes at least one male part and at least one female part, the male part includes a rod member with an external groove, and the female part includes an opening to receive the rod member, the female part further includes a retaining member biased into a latching position within the opening for engaging with the external groove when aligned therewith.

3. The conveying system of claim 1 wherein:

the first buffer table is supported by a plurality of wheel members such that the first buffer table can be pulled away from the conveyor upon release of the first latch arrangement;

the second buffer table is supported by a plurality of wheel members such that the second buffer table can be pulled away from the conveyor upon release of the second latch arrangement.

4. The conveying system of claim 1 wherein:

the first latch arrangement includes a first latching part and a second latching part at spaced apart locations along the first lateral side of the conveyor, and a third latching part and a fourth latching part at spaced apart locations along a first lateral side of the first buffer table, wherein the third latching part is releasably engaged with the first latching part and the fourth latching part is releasably engaged with the second latching part;

the second latch arrangement includes a fifth latching part and a sixth latching part at spaced apart locations along the second lateral side of the conveyor, and a seventh latching part and an eighth latching part at spaced apart locations along a first lateral side of the second buffer table, wherein the seventh latching part is releasably engaged with the fifth latching part and the eighth latching part is releasably engaged with the sixth latching part.

5. The arrangement of claim 1 further comprising:

a first electrical connection between the first lateral side of the conveyor and the first lateral side of the first buffer table, the first electrical connection formed by a first electrical connector component located along the first lateral side of the conveyor and a second electrical connector component located along the first lateral side of the first buffer table, wherein the first electrical connector component is releasably mated to the second electrical connector component;

a second electrical connection between the second lateral side of the conveyor and the first lateral side of the second buffer table, the second electrical connection formed by a third electrical connector component located along the second lateral side of the conveyor and a fourth electrical connector component located along the first lateral side of the second buffer table, wherein the third electrical connector component is releasably mated to the fourth electrical connector component.

6. The conveying system of claim 5 wherein:

the first buffer table includes a conveyor and a conveyor drive and power for the conveyor drive is delivered through the first electrical connection;

the second buffer table includes a conveyor and a conveyor drive, and power for the conveyor drive of the second buffer table is delivered through the second electrical connection.

7. The conveying system of claim 6 wherein:

the first buffer table includes at least one sensor and feedback from the sensor is delivered to a conveying system controller through the first electrical connection;

the second buffer table includes at least one sensor and feedback from the sensor of the second buffer table is delivered to the conveying system controller through the second electrical connection.

8. A conveying system, comprising:

a conveyor for moving items along a primary conveyance path;

a first buffer table releasably connected at a first lateral side of the conveyor via a first releasable latch arrangement including at least one latch part mounted on the first buffer table and at least one latch part mounted on the conveyor, and at least one electrical connector arrangement including at least one connector part mounted on the first buffer table and at least one connector part mounted on the conveyor; and

a second buffer table releasably connected at a second lateral side of the conveyor via a second releasable latch arrangement including at least one latch part mounted on the second buffer table and at least one latch part mounted on the conveyor, and at least one electrical connector arrangement including at least one connector part mounted on the second buffer table and at least one connector part mounted on the conveyor.

9. The conveying system of claim 8 wherein:

the first buffer table is supported by a plurality of wheel members such that the first buffer table can be pulled away from the table upon release of the first releasable latch arrangement;

the second buffer table is supported by a plurality of wheel members such that the second buffer table can be pulled away from the table upon release of the second releasable latch arrangement.

10. The conveying system of claim 8 wherein:

the first releasable latch arrangement includes at least one male latch part and at least one female latch part, the male latch part includes a rod member with an external groove, and the female latch part includes an opening to receive the rod member, the female latch part further includes a retaining member biased into a latching position within the opening for engaging with the external groove when aligned therewith.

11. A conveying system, comprising:

a conveyor for moving items along a primary conveyance path;

a buffer table releasably connectable at a first side of the conveyor via a releasable latch arrangement including a first latch part mounted on the buffer table and a second latch part mounted on the conveyor, and at least one electrical connector arrangement including a first connector part mounted on the buffer table and a second connector part mounted on the conveyor.

12. The conveying system of claim 11 wherein:

the releasable latch arrangement is configured to assure alignment between the first connector part and the second connector part when the buffer table is being engaged with the first side of the conveyor.

13. The conveying system of claim 12 wherein:

as the buffer table is moved into an operating position at the first side of the conveyor, the first latch part and the second latch part are sized and positioned to engage each other before the first connector part and the second connector part engage each other.

14. The conveying system of claim 11 wherein:

the releasable latch arrangement includes a male part and a female part, the first latch part comprises one of the female part or the male part, and the second latch part comprises the other of the female part or the male part.

15. The conveying system of claim 14 wherein:

the male part includes a rod member with an external groove;

the female part includes an opening to receive the rod member, the female part further includes a pin member biased into a latching position within the opening for engaging with the external groove when aligned therewith.

16. The conveying system of claim 15 wherein:

the pin member is manually retractable from its latching position.

17. The conveying system of claim 11 wherein:

the conveyor includes a third latch part located along a second side of the conveyor and a third connector part located along the second side of the conveyor,

and the buffer table is alternatively releasably connectable at the second side of the conveyor via engagement of the third latch part with the first latch part and engagement of the third connector part and the first connector part.

18. The conveying system of claim 11 wherein:

the buffer table includes a conveyor and a conveyor drive and power for the conveyor drive is deliverable through the electrical connector arrangement.

19. The conveying system of claim 18 wherein:

the buffer table includes at least one sensor and feedback from the sensor is deliverable to a conveying system controller through the electrical connector arrangement.
