DESCRIPTION

FIELD OF APPLICATION

[0001] The present invention relates to an apparatus for handling spools and tubes for a textile plant, and to a textile plant comprising such an apparatus for handling spools and tubes.

STATE OF THE ART

[0002] How? known, generally the textile plants of the Multilink type comprise a plurality? of spinning frames that feed a winder, and a transport system for the bobbins to send the bobbins from a spinning frame to the winder, and a transport system for the empty tubes arriving from the winder and destined for a specific spinning machine.

[0003] In this discussion, we will refer to the handling of the spools or tubes, in any case, the handling of the spools takes place through systems suitable for the purpose, for example tube-plate systems, per se? known to the person skilled in the art.

[0004] These systems provide a plate, arranged with a protruding portion, called collar, suitable for being partially inserted into a tube. The pan is guided by the transport system which essentially comprises a conveyor belt on which the pan is placed, and a guide suitable for coupling with the portion of the collar which is not? contained inside the tube. The guide can be made, for example, by means of two portions of sheet metal placed side by side but spaced apart from each other, in such a way as to identify a crack just wider? large than the diameter of the collar.

[0005] In traditional plants of the Multilink type, the spinning frames are arranged in parallel, with one end aligned, so that they can face a single shared transport system.

[0006] Typically, the shared transport system ? substantially composed of two conveyor belts, onto which the cops or empty tubes are automatically loaded. A first conveyor belt transports the bobbins from the respective spinning frame to the winder, and a second conveyor belt transports the empty tubes from the winder to the destination spinning frame.

[0007] In this discussion, with conveyor belt or conveyor, we mean a system suitable for transporting the cops from one position to another. For this purpose, the conveyors can be of the type indicated above, and can comprise lanes onto which the plates can be inserted, and a movable element such as a belt or a chain suitable for moving the plates from one position to another.

[0008] Once the winder has finished processing the yarn by completely emptying the bobbin, the tube is thus? released is placed on the shared transport system and sent to the destination spinning mill.

[0009] In this discussion, the term thread or monofilament or continuous thread refers to a single filament or continuous filament (for example in the case of silk, artificial or synthetic fibres) while the term yarn refers to the set of fibrils of length variable that are parallelized and joined by torsion. In the following you will use? one or the other term without distinction, meaning that the applications of the present invention are not limited to one or the other typology.

[0010] In order to be assigned correctly, each cop is associated with a plate, on which a tracking device is generally placed which allows this plate and therefore the relative cop or tube to be associated with a specific unit. winding machine or to a specific spinning machine.

[0011] The transport systems for bobbins or tubes of the prior art, although widely used and appreciated, are not free from drawbacks.

[0012] For example, in the event that the existing textile plant has spinning machines aligned with each other, and not arranged parallel to each other, since these are devices with dimensions and complexity relevant, isn't it? it is always possible, easy, or convenient from an economic point of view to change their arrangement over time.

[0013] Furthermore, precisely because of the position of the spinning machines, the system that is used for handling the cops? a complex system, since each spinning machine unloads the bobbins independently of the other spinning machines on the same conveyor belt. So, ? It is necessary to set up sophisticated systems to prevent the unloading of a cop by a spinning machine from conflicting with a cop from an unloading of a previous spinning machine which is already on the conveyor belt.

[0014] Furthermore, the apparatuses currently used occupy a large amount of floor space, which could instead be used in other ways.

PRESENTATION OF THE INVENTION

[0015] And? therefore having felt the need to solve, at least partially, the drawbacks and limitations mentioned with reference to the prior art.

[0016] Therefore ? having felt the need to make available an apparatus for handling bobbins and tubes for a textile plant, which allows for better adaptation to the provisions of the individual existing apparatuses.

[0017] Furthermore, ? felt the need for a system that simplifies the spinning frame interconnection structure? winder, reducing its overall dimensions and increasing simplicity? of the textile plant.

[0018] Again, ? having felt the need to make the system for handling bobbins and tubes modular, so that it can be easily replicated in the case of a textile plant with many spinning machines.

[0019] These requirements are satisfied at least partially by an apparatus for handling cops and tubes for a textile plant according to claim 1, and a textile plant comprising this apparatus according to claim 13.

DETAILED DESCRIPTION

[0022] Figure 1 shows in schematic form an apparatus 12 for handling cops and tubes in a textile plant 14 essentially comprising at least one group of at least two spinning machines 100; 200 and at least one winder 300.

[0023] The apparatus 12 comprises a forward conveyor 102; 202, and a return conveyor 104; 204 for each spinning frame 100; 200, wherein the outward conveyor 102; 202 ? suitable for transporting the cops leaving the relative spinning frame 100, 200; and the return conveyor 104, 204 ? suitable for transporting the tubes entering the relative spinning frame 100, 200.

[0024] Furthermore, the apparatus comprises a sorting device 400, which comprises a conveying station 402 in which the forward conveyors 102 converge; 202, and a redistribution station 404 where the return conveyors 104 converge; 204.

[0025] The conveying station 402 and the redistribution station 404 are respectively connected by a conveying conveyor 406 and a redistributing conveyor 408 to a bobbin input line 302 to at least one winder 300, and to a tube output line 304 from at least one 300 winder.

[0026] The conveying station 402 and the redistribution station 404 are suitable for redistributing the cops or tubes respectively to the conveying conveyor 406 or to the return conveyors 104; 204 on the basis of predetermined operating parameters of the bobbins and tubes to be redistributed.

[0027] As can be seen in figure 1, the spinning machines 100; 200 can be substantially aligned with each other.

[0028] According to a possible embodiment, the forward conveyors 102 and the return conveyors 104 of the spinning frame 100 located near the of said sorting device 400 can be arranged internally with respect to the outward 202 and return conveyors 204 of the spinning machine 200 distal to the sorting device 400.

[0029] As can be seen in Figures 1-3, the forward conveyors 102, 202 and the return conveyors 104, 204 can be arranged substantially parallel to each other.

[0030] By way of example only, the spinning machines 100, 200 can have 300-600 heads.

[0031] In figure 2 ? shown is an alternative embodiment of the apparatus of the present invention.

[0032] As can be seen in figure 2, downstream of the sorting device 400, i.e. between the sorting device 400 and the at least one winder 300, can? at least one additional spinning frame 250 be set up.

[0033] The apparatus 14 therefore comprises a forward conveyor 252 and a return conveyor 254 for at least one further spinning frame 250. These conveyors 252, 254, together with the conveying conveyor 406 and the redistribution conveyor 408 converge on a second sorting device 401, comprising a conveying station 403 and a redistribution station 505.

[0034] Advantageously, the second sorting device 401 can be quite similar to the sorting device 400.

[0035] The conveying station 403 and the redistribution station 405 of the second sorting device 401 are connected via a conveying conveyor 407 and a redistributing conveyor 409 respectively to a bobbin input line 302 to the at least one winder 300, and to a tube output line 304 from at least one winder 300.

[0036] According to a possible embodiment, the conveying station 402 of the sorting device 400 can include a conveying disc 410. Furthermore, the redistribution station 404 can also? include a 412 redistribution disk.

[0037] The conveying disc 410 and the redistribution disc 412 comprise at least one lateral seat 414, 416 suitable for engaging a neck of a cap of a spool, and by rotating they move the cap from an input position to the relative station 402, 404 and an exit location from station 402, 404.

[0038] The rotation of the conveying disk 410 and of the redistribution disk 412, can? happen so in s? known to the person skilled in the art, for example through an actuator (not shown) operated by the unit? central control 500 of the textile plant, or through a unit? dedicated control unit (not shown).

[0039] Advantageously, the conveying disc 410 and/or the redistribution disc 412 can comprise six lateral seats 414, 416, as shown in the examples of figures 4-7.

[0040] In accordance with a possible alternative embodiment shown in figure 9, the conveying disc 410 and/or the redistribution disc 412 can comprise three lateral seats 414, 416.

[0041] The lateral seats 414, 416 are adapted to be engaged by a collar of a plate, so that they can be repositioned through a rotation of the conveying disk 410 or of the redistribution disk 412.

[0042] In accordance with a possible embodiment, the disc with six lateral seats 414, 416, whether for conveying or redistribution, given the number of of the seats on its lateral surface pu? be able to rotate in one direction only.

[0043] On the other hand, as regards the embodiment which provides for a disc with three lateral seats 414, 416, whether for conveying or redistribution, it can be be able to rotate in both directions.

[0044] In both cases, the unit? of control 500 of the textile plant can? be suitable to manage these rotations, so that they are, for example, the pi? as short as possible, in terms of time or travel.

[0045] According to a possible embodiment, the conveying station 402 and the redistribution station 404 can be of different types in the same sorting device 400.

[0046] According to a possible embodiment, which can be seen for example in figure 8, the conveying station 402 can be arranged at each forward conveyor 102, 202 with stops 209, 211 suitable for selectively blocking a plate. Said stops 209, 211 can be of the mechanical type, actuated electrically or pneumatically. In any case, can said stops 209, 211 be of the type in itself? known to the person skilled in the art and therefore? will not be explored further.

[0047] Again with reference to figure 8, the redistribution station 404 can comprise a diverter 213 suitable for diverting the plates arriving from the winder to one of the return conveyors 104, 204. The diverter 213 can? be for example of the mechanical type, and operated electrically or pneumatically. In any case, the diverter 213 pu? be of type in s? known to the person skilled in the art and therefore? won't come further described.

[0048] As previously mentioned, the conveying station 402 of the sorting device 400 receives the cops prearranged on their bobbin and relative plate exiting the spinning machines 100, 200. In accordance with a possible embodiment, on the forward conveyor 202 of the spinning wheel 200 pi? distant can? be provided a stop 203. This stop 203 ? suitable to prevent traffic jams in the vicinity? of the sorting disk and, at the same time, uses the same forward conveyor 202, which ? more long, as a temporary storage system for the bobbins. Advantageously, the stop 203 can? be pneumatic. Also, latch 203 can? be managed directly by the unit? of control 500.

[0049] In accordance with a possible embodiment, shown for example in figure 7, the return conveyor 104 of the spinning frame 100 more? near the marshalling yard 400 pu? be set up with a bypass conveyor 105 suitable for directly connecting the return conveyor 104 with the forward conveyor 102 of the spinning machine 100. of the bifurcation between the return conveyor 104 and the bypass conveyor 105 ? a diverter 107 is provided, suitable for diverting the plates towards the return conveyor 104, or towards the bypass conveyor 105.

[0050] Diverter 107 can? be of type in s? known to the person skilled in the art, and therefore? will not be further described.

[0051] The operation of the bypass conveyor 105 foresees that in the eventuality in which the spinning wheel pi? near the sorting station 400 is unable to receive empty tubes, these are sent to the conveying station 402 to be sent back to the winder 300. The winder 300, detecting the presence of an empty tube, will send it? back to the spinning wheel. Advantageously, the procedure can repeat until the spinning wheel returns? operating to receive a tube.

[0052] In other words, according to a possible embodiment, the winder will recirculate? the empty tubes inside the winder itself until the spinning machine returns? operating.

[0053] In accordance with a possible embodiment, overflow sensors 205, 207 can be provided in both forward conveyors 102, 202 coming from the spinning machines 100, 200, suitable for detecting the presence of cops and for sending this information to the unit control panel 500 to stop the feeding of the bobbins into the relative conveyors if necessary. Advantageously, these sensors can be optical presence photocells.

[0054] According to a possible embodiment, the conveying station 402 of the sorting device 400 can comprising at least one reading device 418 of the tracking device arranged on the plate associated with the tube. This reading device 418 ? suitable for reading this tracking device arranged on the plate for the management of the plate and therefore of the cop associated with it.

[0055] According to a possible embodiment, the reading device 418 can be suitable to send this information detected to a unit? central control system 500 for managing the caddy and therefore the shuttle associated with it. Furthermore, the reading device 418 can be suitable for adding information to the tracking device set up on the target.

[0056] According to a possible embodiment, the reading device 418 ? arranged below the conveying disk 410. Advantageously, there can be two reading devices 418, one for each outward conveyor.

[0057] Advantageously, the reading device 418 can be a radio frequency reader. In particular, the reading device 418 can be a radio frequency reader suitable for interacting with an RFID-type tracking device.

[0058] The purpose of the redistribution station 404 is to redistribute the tubes coming from at least one winder 300 to the corresponding spinning machine and, if the tube is not present, restore it so that the empty tube always arrives at the correct spinning machine, ready for being wrapped up in a new spool.

[0059] To properly carry out the addressing, the redistribution station 404 can comprising at least one reading device 420 suitable for detecting and reading a tracking device arranged on a plate associated with a tube. The reading device 420 can? be suitable to send this information detected to a unit? central control system 500 for bobbin management.

[0060] According to a possible embodiment, the reading device 420 can be arranged below the conveying disc 410.

[0061] Advantageously, the reading device 420 can be a radio frequency reader. In particular, the reading device 420 can be a radio frequency reader suitable for interacting with an RFID-type tracking device.

[0062] Will the management system evaluate? where to direct the target and will it recommunicate? to the redistribution station 404 itself allowing to correctly address the target.

[0063] According to a possible embodiment, shown for example in figures 5 and 6, downstream of the redistribution disc 412, for each return conveyor 104, 204 for feeding the spinning machines 100, 200? there is a tube presence device 419, 421 suitable for assessing whether there is a tube present on the plate in transit. If it were absent, the device would position a new tube fitting it suitably onto the plate in transit.

[0064] In figures 1, 2 and 3 ? shown is a textile plant 14 comprising at least one group of two spinning machines 100, 200 and at least one winder 300, which comprises an apparatus for handling cops and tubes of the type just described.

[0065] As can be seen in Figures 1, 2, and 3, the textile plant 14 comprises a bobbin input line 302 to at least one winder 300, and a tube output line 304 from at least one winder 300.

[0066] Furthermore, the textile plant 14 can understand a unit? central control system 500 for managing the cops and tubes connected to said at least one sorting device 400 and to said at least one winder 300.

[0067] The advantages of an apparatus according to the present invention are therefore now evident.

[0068] First, yes? made available an apparatus for handling bobbins and tubes for a textile plant that can better adapt to the provisions of individual existing equipment.

[0069] In other words, the possible arrangements of the spinning frame are much more? versatile compared to the traditional Multilink model and also allow better use of the limited space between the spinning frames.

[0070] Furthermore, the apparatus according to the present invention, ? easily replicable, both in different systems, but also within the same system, as can be seen in the example shown in figure 3.

[0071] Furthermore, the apparatus according to the present invention makes it possible to improve textile plants already in use. constituted, without the need? to move the spinning wheels down? installed.

[0072] In the embodiments described above, the skilled person may, in order to satisfy specific needs, make modifications and/or replacements of the elements described with equivalent elements, without thereby departing from the scope of the attached claims.
