Definitions
- the present invention relates to a device for keeping clean the regions of textile machines in contact with feed threads, particularly for hosiery knitting machines or the like.
- blower nozzles which dispense compressed air jets in order to remove the dust from such regions.
- this solution has the problem that it scatters the dust in the vicinity of the machine, causing problems as regards the healthfulness of the working environment and because the removed dust tends to settle on other parts of the machine.
- the aim of the present invention is to solve the problems described above by providing a device that keeps clean the regions of textile machines that are in contact with feed threads, particularly for hosiery knitting machines or the like, avoiding the scattering into the surrounding environment of the dust generated by the friction of the threads against the elements that guide, support and brake them.
- an object of the invention is to provide a device that effectively avoids pollution of the working environment on the part of the dust generated by the friction of the threads against the elements that guide, support and brake them along their path from the spool to the various thread guides of the machine.
- Another object of the invention is to provide a device that is structurally simple and can be installed on current textile machines, particularly on hosiery knitting machines or the like.
- a device for keeping clean the regions of textile machines that are in contact with feed threads particularly for hosiery knitting machines or the like, characterized in that it comprises a housing that delimits a space around a region where the thread makes contact with a supporting and/or guiding and/or braking element arranged along the path followed by the thread from the spool to a thread guide of the machine, where dust is generated and/or accumulates, and aspirator means which are connected to such space.
- Figure 1 is a side elevation view of the device according to the invention, applied to a thread feeder;
- Figure 2 is a front elevation view of the device according to the invention applied to a thread feeder
- Figure 3 is a top plan view of the device according to the invention applied to a thread feeder. Ways of carrying out the Invention
- the device according to the invention comprises a housing 2, which delimits a space 3 around a region where the thread 4 makes contact with a supporting and/or guiding and/or braking element 5 along the path followed by the thread 4 from the spool to a thread guide of the machine, and aspirator means 6 connected to said space 3.
- the device according to the invention is applied to a conventional feeder which is generally designated by the reference numeral 7.
- the space 3 delimited by the housing 2 contains the regions of the feeder 7 at which the thread is subjected to friction against the various elements of the feeder 7, such as for example braking brushes, guiding elements, and the exit passage 8, generally formed by a ceramic ring.
- the aspirator means comprise a duct 9, which is connected to an aspirator 10 and is provided with an inlet 9a connected to the space 3.
- filter 11 is designed to retain internally the dust aspirated along the duct 9. If a plurality of aspirator ducts connected to different housings 2 mounted on a same machine or on a plurality of machines are provided, it is possible to provide also a single filter arranged on a manifold, whereto the various aspirator ducts converge.
- filter 11 can be of the removable type in order to clean it periodically.
- the housing 2 whose dimensions and shape can vary according to the requirements, delimits a space 3 that is arranged at least on the side where the thread 4 enters through said passage, i.e., the side at which the greatest quantity of dust forms and deposits due to the sliding of thread through said passage.
- the housing 2 is mounted on the supporting and/or guiding and/or braking element or on a suitable supporting structure without a seal with respect to the outside or in such a manner that the suction generated by the activation of the aspirator 10 causes, without problems, a stream of aspirated air through the space 3.
- Operation of the device according to the invention is as follows.
- the thread 4 in its sliding against the various supporting and/or guiding and/or braking elements arranged along the path of the thread from the spool to the thread guide that feeds it to the needles of the machine, generates dust which is retained within the space 3 thanks to the housing 2.
- the actuation of the aspirator 10 causes the gradual aspiration of the dust along the duct 9 and its retention within the filter 11. In this manner, the dust that forms in the space 3 is removed constantly and the thread supporting and/or guiding and/or braking elements, enclosed by the housing 2, stay clean.
- the device according to the invention differently from the blowers currently used to keep clean the thread supporting and/or guiding and/or braking elements, avoids scattering the dust into the surrounding environment but instead captures it and collects it optionally in a filter, thus avoiding contaminations of the working environment, and also avoids scattering the dust onto the other components of the machine.
- the device according to the invention fully achieves the intended aim and objects, since by removing and capturing the dust that forms on the elements of the machine affected by the sliding of the threads, it keeps such elements constantly clean and at the same time avoids scattering dust into the working environment.
- Another advantage of the device according to the invention is that it limits the use of housings to protect elements of the machine that are particularly sensitive to the problem of cleanness.
- Another advantage of the device according to the invention is that it keeps constantly clean the thread supporting and/or guiding and/or braking elements, avoiding abnormal friction on the threads and therefore avoiding qualitative changes to the manufactured article.
- the materials used may be any according to requirements and to the state of the art.
