Cleaning device
View Patent ↗A cleaning device for cleaning a conveyor system including a slotted track that defines an elongate path along which product is moved and that has opposed glide surfaces from which product is suspended. The conveyor system also includes a wall that is disposed above the track and that cooperates with the track to define a product passageway along the elongate path. The cleaning device includes a drive unit, a wheel rotatably coupled to the drive unit and engageable with the wall within the product passageway to move the drive unit along the slotted track, a glide coupled to the drive unit and engageable with the glide surfaces to support the drive unit on the slotted track, and a cleaning implement coupled to the drive unit to clean the track.
1. A cleaning device for cleaning a conveyor system including a slotted track that defines an elongate path along which product is moved and that has opposed glide surfaces from which product is suspended, the conveyor system also including a wall disposed above the slotted track and cooperating with the track to define a product passageway along the elongate path, the cleaning device comprising:
a drive unit;
a wheel rotatably coupled to the drive unit and biased into engagement with the wall within the product passageway to move the drive unit along the slotted track;
a glide coupled to the drive unit and engageable with the glide surfaces to support the drive unit on the slotted track; and
a cleaning implement coupled to the drive unit and positionable within the product passageway to clean the track.
2. The cleaning device of claim 1 , wherein the wheel defines a central plane of the cleaning device and the glide is aligned with the wheel along the central plane.
3. The cleaning device of claim 1 , wherein the drive unit includes a housing, the cleaning device further comprising a power source and a motor disposed in the housing and operably coupled to the wheel to move the drive unit along the slotted track.
4. The cleaning device of claim 3 , further comprising a controller in electrical communication with the motor and the power source to control movement of the drive unit.
5. The cleaning device of claim 4 , further comprising a sensor device coupled to the drive unit and positioned to detect a track marker positioned along the slotted track, wherein the sensor device is in communication with the controller, and wherein movement of the drive unit is controlled in response to detection of the track marker.
6. The cleaning device of claim 5 , wherein the sensor device is operable to detect a magnetic field of the track marker.
7. The cleaning device of claim 5 , wherein the drive unit is adapted to at least one of start, stop, accelerate, and slow down in response to detection of the track marker.
8. The cleaning device of claim 5 , wherein the drive unit is adapted to reverse direction in response to detection of the track marker.
9. The cleaning device of claim 1 , wherein the cleaning implement is attached to the glide.
10. The cleaning device of claim 9 , further comprising an attachment mechanism coupled between the glide and the cleaning implement, and wherein the cleaning implement is removably coupled to the attachment mechanism.
11. The cleaning device of claim 10 , wherein the attachment mechanism includes a stabilizer engageable with the track to support the attachment mechanism above the track.
12. The cleaning device of claim 1 , further comprising a suspension arm pivotably coupled to the drive unit and biased to force the wheel into engagement with the wall, and wherein the glide is coupled to a distal end of the suspension arm.
13. The cleaning device of claim 12 , wherein the suspension arm is a first suspension arm and the glide is a first glide coupled to the first suspension arm adjacent a first end of the drive unit, the cleaning device further including a second suspension arm pivotably coupled to the drive unit and biased to cooperatively force the wheel into engagement with the wall, and a second glide coupled to a distal end of the second suspension arm and located adjacent a second end of the drive unit opposite the first end.
14. The cleaning device of claim 13 , further comprising a hook coupled to the second glide to manually manipulate the drive unit within the slotted track.
15. The cleaning device of claim 12 , wherein the glide includes an alignment key and is pivotably coupled to the suspension arm by a connector pin.
16. The cleaning device of claim 15 , wherein the glide defines a slot and the suspension arm has a pivot pin disposed in the slot to limit pivotal movement of the glide.
17. The cleaning device of claim 15 , wherein the alignment key has a flange shaped to substantially match the shape of an upper end of the product distributed through the conveyor system.
18. The cleaning device of claim 17 , wherein the flange is substantially circular and has a diameter substantially corresponding to the diameter of a neck finish of the product supported by the track.
19. The cleaning device of claim 17 , wherein the flange has a first engagement surface and a second engagement surface that is wider than and tapered from the first engagement surface toward the perimeter of the flange.
20. The cleaning device of claim 1 , further comprising a cleaning head including a cleaning pad coupled to a side of the drive unit to clean a portion of the conveyor system.
21. The cleaning device of claim 1 , wherein the wheel is resiliently biased under spring force into engagement with the wall within the product passageway.
