Abstract

A cleaning machine for a textile factory has a filter through which air moves from the machine under pressure against textile machinery for loosening lint. A second filter in a suction chamber of the machine collects the lint as it is moved through the chamber of the machine collects the lint as it is moved through the chamber by suction generated in the machine. The machine traverses a fixed path over the textile machinery and the first filter is cleaned as the machine moves past a vacuum cleaner nozzle. The second filter is cleaned by moving it first out of the suction chamber, this movement bringing it into position to be cleaned by the same vacuum nozzle. During cleaning of the filters, a shutter shuts communication between the filters and the air-moving mechanism of the machine. The shutter and the movable filter are actuated incidental to movement of the machine it its fixed path under predetermined control.

Claims

1. In a combination of the class described, a traversing machine having an intake chamber for a pressure-blower means, and a suction chamber for a suction-blower means, a first screen for one of said chambers positioned on said machine for moving with said machine relatively to a vacuum cleaner nozzle for the cleaning of the said screen by said vacuum cleaner as said machine moves past said nozzle, a second screen for said other chamber, means for moving said second screen relatively to said machine into a position for cleaning also by said nozzle, said intake chamber and first screen being at one side of a linear path traversed by said machine, said suction chamber and said second screen being at the opposite side of said linear path, and movement of said second screen is transverse to said path so that both screens may be cleaned by one vacuum nozzle positioned relatively to said path for coaction with said first screen as said machine moves in said path.

2. In the combination of claim 1, the feature that the first screen is fixed and the second screen slides over said first screen into coextensive juxtaposition thereto for cleaning by said nozzle, said first screen being exposed to the atmosphere at the top of said pressure chamber and said second screen being within said suction chamber and moved outwardly thereof for cleaning.

3. In the combination of claim 1, the feature that said blower means are in the form of a separate motor-operated blower for each chamber.

4. In the combination of claim 1, the feature that there are shutter means for closing communication between said chambers and said blower means when said screens are being cleaned.

5. In the combination of claim 1, the feature that said pressure-blower means is in communication with a pressure duct positioned transversely of said machine at one end thereof tRansverse to the said linear path while said suction chamber is in communication with a suction duct positioned transversely of the machine at the other end thereof, and also transverse to said linear path, a pair of vertically aligned pressure tubes, one tube in communication with one end of said pressure duct and the other in communication with the other end of said pressure duct, and a pair of vertically aligned suction tubes similarly communicating with said suction duct.

6. In the combination of claim 5, the feature that said pressure-blower means and said suction-blower means are each a separate motor-operated fan with one fan at each side of the linear path, whereby said motors, said fans and said ducts and tubes are balanced relatively to said linear path whereby to facilitate the mounting of the machine for movement on a single rail.

7. In the combination of claim 5, the feature that shutter means are positioned to shut off communication between said blower means and tubes when said screens are being cleaned.

8. In a machine of the class described mounted for movement on a rail or the like in a fixed path and having a screen adapted for exposure to a vacuum cleaner for cleaning said screen, means positioning said screen relatively to said path so that when said screen and machine move in said path said screen will be at one side relatively to said vacuum cleaner whereby not to be exposed to the action of said cleaner, the improvement that comprises means mounting said screen for linear movement relatively to said machine into a position for exposure to said cleaner, and means for moving said screen on said mounting means.

9. In the combination of claim 8, the feature that said means for moving said screen comprise a friction drive wheel, a friction drive wheel mounting device movably mounted on said machine, means mounting said wheel for rotation on said device, means for moving said device to bring the periphery of the wheel into and out of contact with a stationary surface in said path, said wheel rotating on its mounting when brought into contact with said stationary surface, and means between said screen and wheel whereby rotation of said wheel moves said screen.

10. In the combination of claim 9, the feature that said screen is connected to said drive wheel by a cable.

11. In the combination of claim 10, the feature that said cable is so secured relatively to said wheel that rotation of said wheel in either of opposite directions will exert pull on said cable.

12. In the combination of claim 9, the feature that said wheel-mounting-device is an arm, and a solenoid for moving the arm to bring the drive wheel against the stationary surface upon excitation thereof.

13. In the combination of claim 12, the feature that said solenoid is excited upon the movement of the machine into a particular position in said path.

14. In the combination of claim 8, the feature that said machine has a fixed screen positioned relatively to said mounting means so that it is just under said movable screen when said movable screen has been moved to expose it to said cleaner, and the reverse movement of said movable screen to said one side of said path exposing said fixed screen to said cleaner.

15. In the combination of the class described , a traversing machine having an intake chamber for a pressure-blower means, a suction chamber for a suction-blower means, a first screen for one of said chambers positioned on said machine for moving with said machine relatively to a vacuum cleaner nozzle for the cleaning of the said screen by said vacuum cleaner as said machine moves past said nozzle, said machine being mounted on a rail and provided with means for moving said machine on said rail in a linear path in which is aligned the longitudinal axis of the machine, said pressure-blower means being a fan mounted on said machine at one side of the rail while said suction means is a fan mounted on said machine at the other side of the rail, said first sCreen being fixed on said machine and exposed to the atmosphere at the top of the machine at one side of the rail, said second screen being mounted for sliding motion transversely of the machine from a position over said first screen to a position within said suction chamber, said suction chamber being at the top of the machine and enclosing said second screen when said second screen is in said chamber, shutter means for closing communication between said fans and said chambers, means actuated incidental to movement of said machine relatively to said rail for imparting movement to said shutter means, a duct positioned on said machine transversely thereof at each end, one duct communicating with one fan and the other duct with the other fan, and a vertical tube extending downwardly from each end of each duct whereby one of said tubes at each side of the machine is a pressure tube and the other is a suction tube.
