Description

The present invention relates to an integrated device for a system for transporting bobbins and tubes between a roving frame and a spinning frame of a spinning line.

As is well known, the bobbin formed on the roving frame comprises a tube around which the roving drawn by the roving frame is wound, and is conveyed to the spinning frame. The bobbins to be treated are found in the spinning frame suspended on the frame, from which the rovings processed by the spinning frame emerge. When the bobbins to be processed are exhausted, they are replaced with bobbins coming from the roving frame.

Exhausted bobbins consist of tubes without any roving (called "empty tubes") or tubes with a plurality of remaining rovings (called "contamination tubes").

The contaminated tubes (sometimes empty) are cleaned with special equipment, usually called a "cleaner", to remove the remaining rovings and obtain empty tubes.

The empty tubes coming from the cleaner and the ones taken from the spinning frame are returned to the roving frame, where they replace the bobbin formed in between and continue to form new bobbins.

These steps are performed manually or with a fully or partially automated mechanization system.

In the case of an automatic system, an automatic rail transfer system is provided between the roving frame and the spinning frame. In the vicinity of the roving frame, the transport system works with a bobbin that is fed to the spinning frame and a changer that changes the tubes coming from the spinning frame. In addition, the transport system works with a cleaning device that removes residual roving from the contaminated tube before it is fed to the roving frame.

The performance of these operations, despite a high degree of automation, requires a certain amount of execution time and, given the large number of bobbins and tubes to be managed, can substantially affect the economic characteristics of the entire plant. It is clear that there is.

It is an object of the present invention to provide an integrated device for a system for transporting bobbins and tubes between a roving frame and a spinning frame, which makes it possible to reduce the overall execution time of cleaning and replacement steps.

A spinning frame side hook/release device 90 ″ associated with 12 defines a spinning frame side hook/release axis K.

In some cases, in the first configuration of the integrated device 50, the first support plate 52a and the second support plate 52b are in the retracted position, that is, near the axis of rotation Z.

In the next configuration (FIG. 4b), the first support plate 52a and the second support plate 52b are horizontally translated along the horizontal translation direction X by the drive of the horizontal translation means, and the support portion 54a carried by the first plate 52a is The support 54b that is aligned with the bobbin 10, that is, coaxial with the roving frame side hook/release axis J and carried by the second plate 52b, is aligned with the contamination tube 12, that is, the spinning frame side hook/ It becomes coaxial with the release axis K and moves from the retracted position to the advanced position.

Aligned with the hook/release device 90″, in particular coaxial with the spinning frame side hook/release axis K, from the retracted position to the advanced position.

In the next configuration (FIG. 4l), the first support plate 52a and the second support plate 14b are vertically translated along the vertical translation direction Y by the drive of the vertical translation means, and in particular, are raised from the lowered position to the raised position, The empty tube 14 and bobbin 10 work with each hook/release device 90', 90" and can remain suspended from the rail 22' and second track 26'.

Thus, the bobbin and empty tube release steps are performed separately, one bobbin and one empty tube per cycle.

Further, in the next configuration (FIG. 4m), the first support plate 52a and the second support plate 52b are vertically translated along the vertical translation direction Y by the drive of the vertical translation means, and particularly, they are moved down from the raised position to the lowered position. Pass through, releasing empty tube 14 and bobbin 10, leaving them suspended from rail 22' and second track 26', respectively.

In some cases, integrated device 50 returns to its initial configuration, with first support plate 52a and second support plate 52b in the retracted position (FIG. 4a).

Driving the main carrier 22 makes another bobbin 10 available to the integrated device 50, and driving the second carrier 26 makes another contamination tube 12 available to the integrated device 50.

In other words, according to the method of operation of the spinning line according to the invention, between the cleaning of the contaminated tube 12 and the release of the empty tube 14, said empty tube 14 or contaminated tube is no longer released and is picked again (picked). ).

The innovation reduces the overall time required to change tubes and bobbins and clean contaminated tubes, so the above integrated device meets the needs described above with reference to known techniques. ..

In fact, according to the invention, the cleaning of the contaminated tube takes place at substantially the same time as the position change between the bobbin and the contaminated tube.

Advantageously, furthermore, the spinning line with the integrated device according to the invention is particularly reliable as it limits the use of empty tube hooks and commuter for release.

As is well known, the commuter, the hook/release device for bobbins and empty or contaminated tubes, is the most delicate part of the transport system between the roving frame and the spinning frame, in order to reduce the number of failures and malfunctions. , Need to reduce their use as much as possible.

Precisely for this purpose, according to the invention, the integrated device operates directly on the rails which feed the roving frame, thereby picking bobbins and feeding empty tubes and feeding the spinning frame. By working directly above, picking of contaminated tubing and bobbin feeding can be performed, avoiding intermediate steps and unnecessary use of commuter.

In the above embodiments, the step of cleaning the contamination tube is performed in a retracted cleaning position of the plate carrying the contamination tube.

According to another variant, the cleaning step is carried out after a further rotation of the plate carrying the tube, for example 90° to the retracted position.

According to yet another variant, the cleaning step is performed after the step of exchanging the position between the contamination tube and the bobbin.
