Abstract

A device for maintaining a pneumatic conveyance line can include a body having one or more wings. In some examples, the body is configured to be positioned between opposing rails of a pneumatic conveyance track with the one or more wings positioned on a respective opposing rail of the track. The wings can carry one or more agents for at least one of cleaning and lubricating the track. As the device is pushed along the track, the device can clean and/or lubricate the track.

First claim

The invention claimed is:

1. A device for servicing a pneumatic conveyance line comprising:
a body having a length extending from a leading end to a trailing end and a width extending perpendicularly to the length, the width of the body defining a pair of wings projecting in opposed directions from a centerline of the body,
wherein the body is configured to be positioned between opposed rails of a pneumatic conveyance track with each of the pair of wings positioned on a respective one of the opposed rails,
the pair of wings carry an agent for at least one cleaning and lubricating the opposed rails of the pneumatic conveyance track, and
the body further comprises at least one rail projecting downwardly from the pair of wings, the at least one rail being configured to be positioned between the opposed rails of the pneumatic conveyance track.

2. The device of claim 1 , wherein the trailing end of the body has a shape corresponding to a shape of an object to be conveyed on the pneumatic conveyance track.

3. The device of claim 2 , wherein the object is a circular shaped bottle, and the shape of the trailing end of the body is a rounded groove configured to mate with the circular shaped bottle positioned in the pneumatic conveyance track and used to propel the body along the pneumatic conveyance track.

4. The device of claim 1 , wherein each of the pair of wings and the at least one rail, in combination, define a groove having a top surface formed by a bottom surface of one of the pair of wings and a sidewall surface formed by the at least one rail, wherein the top surface is configured to be positioned in contact with an upwardly facing surface of a respective one of the opposed rails and the sidewall surface is configured to be positioned in contact with a sidewall of the respective one of the opposed rails.

5. The device of claim 1 , wherein the body comprises an elongated body with the length being greater than the width.

6. The device of claim 5 , wherein the length ranges from 1 centimeter to 25 centimeters, the width ranges from 1 centimeters to 15 centimeters, and the body has a thickness less than 25 centimeters.

7. The device of claim 1 , wherein the device has a total weight greater than 30 grams and less than 300 grams.

8. The device of claim 1 , further comprising at least one sheet impregnated with the at least one of a cleaning agent and a lubricating agent, the at least one sheet being attached to the pair of wings such that the pair of wings carry the agent by carrying the sheet.

9. The device of claim 8 , wherein the body comprises at least two sections configured to mechanically engage together with the at least one sheet positioned therebetween.

10. The device of claim 8 , wherein the at least one sheet covers at least a bottom surface of each of the pair of wings configured to contact a respective one of the opposed rails.

11. The device of claim 1 , wherein the body further comprises a pair of retaining ledges extending outwardly from the at least one rail parallel to the pair of wings, wherein a bottom surface of each of the pair of wings, a sidewall of the at least one rail, and a top surface of a corresponding one of each of the pair of retaining ledges collectively define a channel configured to be positioned over each of the opposed rails.

12. A device for servicing a pneumatic conveyance line comprising:
a body having a length extending from a leading end to a trailing end and a width extending perpendicularly to the length, the width of the body defining a pair of wings projecting in opposed directions from a centerline of the body, and
at least one sheet impregnated with the at least one of a cleaning agent and a lubricating agent, the at least one sheet being attached to the pair of wings such that the pair of wings carry the sheet,
wherein the body is configured to be positioned between opposed rails of a pneumatic conveyance track with each of the pair of wings positioned on a respective one of the opposed rails, and
the body comprises at least two sections configured to mechanically engage together with the at least one sheet positioned therebetween, thereby attaching the sheet to the pair of wings.

13. The device of claim 12 , wherein the trailing end of the body has a shape corresponding to a shape of an object to be conveyed on the pneumatic conveyance track.

14. The device of claim 12 , wherein each of the pair of wings and the at least one rail, in combination, define a groove having a top surface formed by a bottom surface of one of the pair of wings and a sidewall surface formed by the at least one rail, wherein the top surface is configured to be positioned in contact with an upwardly facing surface of a respective one of the opposed rails and the sidewall surface is configured to be positioned in contact with a sidewall of the respective one of the opposed rails.

15. The device of claim 12 , wherein the body comprises an elongated body with the length being greater than the width.

16. The device of claim 15 , wherein the length ranges from 1 centimeter to 25 centimeters, the width ranges from 1 centimeters to 15 centimeters, and the body has a thickness less than 25 centimeters.

17. The device of claim 12 , wherein the device has a total weight greater than 30 grams and less than 300 grams.

18. The device of claim 12 , wherein the at least one sheet covers at least a bottom surface of each of the pair of wings configured to contact a respective one of the opposed rails.

19. The device of claim 12 , wherein the body further comprises at least one rail projecting downwardly from the pair of wings and a pair of retaining ledges extending outwardly from the at least one rail parallel to the pair of wings, wherein a bottom surface of each of the pair of wings, a sidewall of the at least one rail, and a top surface of a corresponding one of each of the pair of retaining ledges collectively define a channel configured to be positioned over each of the opposed rails.

20. The device of claim 13 , wherein the object is a circular shaped bottle, and the shape of the trailing end of the body is a rounded groove configured to mate with the circular shaped bottle positioned in the pneumatic conveyance track and used to propel the body along the pneumatic conveyance track.
