Description

Technical Field

[0001] The present invention relates to a cooling well device for combining and automatically guiding synthetic filaments in a cooling well, a melt spinning device for producing synthetic filaments, and a winding device for winding synthetic filaments with a cooling device. Background Art

[0002] Devices for guiding and applying synthetic filaments from a melt spinning device to a winding device are known from the general prior art.

[0003] DE10117087A1 describes a device for melt spinning at least one multifilament. The device has a spinning device, a cooling device, a processing device, and a winding device, which are arranged vertically one above the other. For the initial application of the filaments, a filament applicator is provided, which has a guide rail and a suction nozzle guided on the guide rail. The guide rail extends at least as far as possible from the cooling device to the winding device, so that the suction nozzle can pick up the filaments in the area of the cooling device and guide them to the winding device.

[0004] EP3312120B1 describes and claims a spun yarn winding system, including spun yarn winding machines aligned in a predetermined direction and a yarn threading robot that can move in a predetermined direction and can perform yarn threading onto the spinning winding machines. The yarn threading robot has a drive unit configured to move a robot-side supply line connection member, which is intended to be connected to or disconnected from a system-side supply line connection member.

[0005] WO2018153739A1 describes an operating machine for applying yarn to a spinning position of a winding device. The operating machine can be guided to each spinning position to apply the filaments. To obtain reliable guidance and accurate positioning during filament application, the operating machine is held in the spinning position by at least one removable support mounted on the winding device.

[0006] WO2020058046A1 discloses an operating robot for applying filaments to a spinning position of a winding device. The operating robot can be guided to each spinning position to apply the filaments. For this purpose, the robot has a suction injector. To connect the suction injector to a compressed air source and to a waste yarn box, a supply bracket is associated with the operating robot and is connected to the operating robot via a compressed air line and a waste line.

[0007] The application of synthetic filaments to the spinning positions of the winding device can be achieved using the proposed devices.

[0008] However, for fully automatic application in equipment for producing and winding filaments, the application position in the cooling well, which is located behind the spinning box and where the synthetic filament yarn is extruded, particularly requires the synthetic filament to be provided by an experienced operator. For this purpose, the operator has to manually grasp the filament extruded from the spinning box near the spinning box and apply it to the application position in the cooling well. This can lead to accidents. Additionally, it can be extremely time-consuming and dangerous when the operator cannot correctly grasp the filament and wears the wrong protective equipment. Summary of the Invention

[0009] Therefore, an object of the present invention is to provide a cooling well device for combining and automatically guiding synthetic filaments in a cooling well, by means of which the above problems can be prevented or at least alleviated.

[0010] Furthermore, an object of the present invention is to provide a melt spinning device for producing synthetic filaments, which has a device for combining and automatically guiding synthetic filaments, by means of which the above problems can be prevented or at least alleviated.

[0011] Regarding the cooling well device according to the present invention, this object is achieved by a device for combining and automatically guiding synthetic filaments.

[0012] According to one aspect of the present invention, there is provided a cooling well device for combining and automatically guiding synthetic filaments in a cooling well, wherein the filaments can be bundled and guided in the cooling well by means of a plurality of converging filament guides to combine the filaments to form a filament bundle, and wherein the plurality of converging filament guides can be automatically moved in the cooling well on a converging support, so that for feeding to a feed well, the filament bundle position can be changed between a collection position for combining the filaments to form a filament bundle and a first feed position arranged adjacent to each other and / or a second feed position for feeding the combined filament bundle to a winding device for winding the filament bundle.

[0013] Herein, in particular, the cooling well device should be understood as the cooling area between the spinning box for extruding synthetic filaments and the feed well for feeding the extruded filaments to the winding device.

[0014] By means of the converging filament guides movably mounted on the converging support according to the present invention, the filaments can be bundled to form a filament bundle and automatically moved to a predetermined feed position.

[0015] Here, a first feed position allowing the collection of the filament bundle at a predetermined position can be provided. As an alternative to the first feed position, a second feed position can also be provided, in which the filament bundle is positioned by means of the converging filament guides such that transfer to a filament capture funnel at the feed well can be achieved.

[0016] Advantageously, with the cooling well device according to the invention, the feeding and application of the synthetic filaments on the winding device can also be carried out fully automatically in the area of the cooling well, so that the accident risk for the operator can be prevented and the automatic complete application of the filaments in the cooling well can be achieved. In addition, the application of the filaments in the cooling well on the melt spinning device can be carried out there without an operator. The operator can advantageously monitor the filament application at the level of the winding device and does not need to be located at the level of the melt spinning device.

[0017] According to another embodiment of the cooling well device, the cooling well of the converging support is located between the spinning box for extruding synthetic filaments and the feed well for feeding the filament bundle to the winding device.

[0018] The positioning of the converging support in the cooling well allows for the automatic and precise application of the filaments on the converging filament guide, which combines the filaments to form a filament bundle. The filament bundle is combined in the winding device by means of a vortex device to form a windable filament and is wound onto a bobbin for further processing.

[0019] According to another embodiment of the cooling well device, each converging filament guide is mounted on the converging support in such a way that it can be pivoted automatically and / or displaced automatically.

[0020] The pivoting of the converging filament guide on the converging support is particularly intended to mean a 180° position change towards and away from the spinning box.

[0021] The automatic displacement of the converging filament guide on the converging support is particularly intended to mean the reciprocating movement of the converging filament guide on the converging support.

[0022] According to yet another embodiment of the cooling well device, these converging filament guides can be displaced in the direction of extension of the converging support from a collecting position for receiving and bundling the filaments to a first feeding position, such that these converging filament guides are positioned adjacent to each other laterally, so that the filament bundle can be collected in the feed collecting tube, which is located in the feed well and has a smaller cross-section than the feed well, and / or displaced into a cutting position, such that the converging filament guides are positioned adjacent to each other laterally, so that the filament bundle can be jointly severed by a cutting machine.

[0023] According to the embodiment just presented, the converging filament guides can be reciprocated in the direction of extension of the converging support, so that they can be positioned in the collecting position and the first feeding position for feeding the collected filament bundle into the feed well, in particular the collecting tube.

[0024] The collecting tube is arranged transversely in the feed well and can be opened and closed.

[0025] Via the collecting tube, the collected filament bundle can then be fed to a winding device, which also has an automatic application system, more quickly and with a higher point accuracy, so that together with the automatic application system of the cooling well device and the winding device according to the invention, a fully automatic application from the spinning box as far as possible to the winding device can be achieved without human intervention.

[0026] Furthermore, the converging thread guide can be displaced along the extension direction of the converging support as far as possible to the cutting position, so that, for example, in the case of a thread break, the filaments can already be severed in the cooling well, with the result that waste can be avoided.

[0027] According to another embodiment of the cooling well device, a thread cutting device for filament severing and / or a suction gun for filament suction are movably mounted on the converging support.

[0028] In order to better remove the severed filaments, the suction gun can also be arranged on the converging support, which is intended to suck the filaments extruded from the spinning box, so that the filament strands that cannot yet be applied do not further contaminate the winding device, for example, when an error that needs to be remedied has occurred during the application to the winding device.

[0029] According to another embodiment of the cooling well device, each converging thread guide has a guiding part, which can be moved towards the spinning box to a receiving position and away from the spinning box to a feeding position.

[0030] In another embodiment of the cooling well device, the converging thread guides cannot be displaced along the converging support, but are pivotally mounted on the converging support in such a way that their guiding parts can be pivoted towards or away from the spinning box.

[0031] The guiding part can have a corresponding coating, which prevents the converging thread guide from being torn and / or worn by the filaments. This coating can contain, for example, ceramics.

[0032] According to another embodiment of the cooling well device, the filaments can be captured at the channel inlet of a movable filament capture funnel, which can be automatically moved from a starting position for capturing the filaments at the spinning box to an intermediate position and / or a feeding position for applying the filaments to the converging thread guide.

[0033] As a supplement and / or alternative to the converging thread guide displaceable along the converging support, a filament capture funnel can be provided, by means of which the filaments can be directly removed at the spinning box and fed to the feed well.

[0034] According to another embodiment of the cooling well device, the filament capture funnel has a plurality of channels for each filament bundle, which channels combine to form a channel outlet, and a suction mechanism for filament bundle suction can be mounted on the channel outlet.

[0035] In order to better guide and bundle the filaments, the filament capture funnel has a channel for each filament bundle, and the channels merge at the channel outlet, so that the filament bundles can also be fed point by point to the winding device for collecting the filament bundles.

[0036] According to an additional embodiment of the cooling well device, at the channel inlet of the filament capture funnel, a filament cutting device for cutting the filaments and / or a suction gun for sucking the filaments are movably mounted along the channel inlet.

[0037] In the embodiment with a filament capture funnel, a cutting device can be arranged at the height of the channel inlet of the filament capture funnel so that the filament bundle can be selectively severed and cut. A suction gun can be additionally arranged at the cutting device, which can then immediately suck the severed filaments and feed them to a waste filament collection box connected to the suction gun.

[0038] This object is achieved by a melt spinning device.

[0039] According to one aspect of the present invention, there is provided a melt spinning device for producing synthetic filaments, which has a spinning box for extruding synthetic filaments and a winding device for winding synthetic filaments, and the synthetic filaments can be fed from the melt spinning device to the winding device through a cooling well and / or a feed well, wherein the cooling well device according to at least one of the above embodiments is arranged in the cooling well.

[0095] Figure 1.1 and Figure 1.2 shows a device for producing and winding synthetic fiber F, Figure 1.1 in an overall view, andFigure 1.2 is shown in detail. The equipment for producing and winding synthetic fiber F has a melt spinning device 1 with a spinning box 2 for extruding synthetic filaments F from a plastic melt and a winding device 14 for winding the synthetic filaments F.

[0096] Figure 1.1 Basically, the winding device 14 with a feed wire well 4 and a cooling well 3 is shown.

[0097] The melt spinning device 1 with the spinning box 2 and the associated cooling well 3 is schematically shown in Figures 2 to 10 together with a cooling well device for automatically applying filaments on a converging filament guide 22 according to the present invention. The converging filament guide 22 is movably mounted on a converging support 21 within the cooling well 3, as shown, for example, in Figure 1.2 the detailed view of.

[0098] In Figure 1.1 the winding device 14 can also be arranged in a double configuration. Two cooling wells 4 are thus shown in Figure 1.1 while the opposite winding device 14 is not shown for simplicity of display.

[0099] The filaments FF are extruded from the plastic melt through the spinning box 2 into the cooling well 3, as shown, for example, in Figure 2 the view of.

[0100] Therefore, the application of the filaments FF in the winding device 14 can also be carried out automatically. The filaments FF can be combined on the converging filament guide 22 of the cooling well device according to the present invention to form a filament bundle FB. The filament bundle FB can then be collected as a filament bundle skein FBS in a collection pipeline 8 and sent to a drafting zone 10 on the winding device 14, with the help of a winding suction gun 12 on the winding device.

[0101] The collection pipeline 8 is located in the corner area of the feed wire well 4 and is used for automatic application on the winding device 14, because more precise positioning and feeding of the filament bundle skein FBS containing many filament bundles can be carried out with the collection pipeline 8.

[0102] At the end facing the cooling well 3, the collection pipeline 8 has a collection pipeline opening 6 where the fiber bundle is to be positioned and can be shifted towards the winding device 14.

[0103] A sealing plate 7 is appropriately arranged between the cooling well 3 and the feed wire well 4 so that the cold air conveyed by the cooling well can be guided downward to the feed wire well 4 and cannot escape in the connection area between the cooling well 3 and the feed wire well 4.

[0104] Figure 1.2 is shown Figure 1.1Detail view of the open cooling well 3. The cooling well 3 is shown open as such to better show the relevant features.

[0105] After the filaments FF have been fully applied to form the filament bundle FB, the cooling well 3 is closed so that cold air can be directed along the cooling well and can accordingly cool the filaments FF or the filament bundle FB.

[0106] The pretreatment support 18 is installed inside the cooling well 3 and the converging support 21 is installed below the pretreatment support 18 in the filament running direction. The automatically movable converging filament guide 22 is indicated on the converging support 21. This converging filament guide 22 or these converging filament guides 22 correspond to the number of filaments FB that can be extruded by the spinning box 2.

[0107] The pretreatment support 18 can have sensors for monitoring the filaments FF and / or a fluid dispenser for wetting the filaments FF with a suitable fluid, for example.

[0108] The cooling well device also has a filament converging device 20, which includes a converging support 21 and a converging filament guide 22.

[0109] The cooling well inlet 16 is also indicated Figure 1.2 in.

[0110] It can also be seen that the collection line 8 is in place in the corner region of the feed filament well 4. The collection line 8 has a collection line opening 6 with a connection for compressed air supply, which connection can be arranged for the downward guidance of the air flow of the filament bundle sliver FBS.

[0111] Figure 2 The cooling well 3 with a first embodiment of the cooling well device according to the invention is shown schematically simplified.

[0112] In Figure 2 the embodiment shown, the filaments FF have been collected and applied to a plurality of converging filament guides 22 to form a filament bundle FB. The filament bundle FB can also be referred to as a filament F and can be wound onto a bobbin by the winding device 14.

[0113] A plurality of converging filament guides 22 are located on the converging support 21 in the collection position SP. In the collection position SP, the filaments FF are combined to form the filament bundle FB.

[0114] The converging filament guide 22 has a guiding portion 23 by means of which the filaments can be combined into the filament bundle FB.

[0115] In order to prepare the filaments FF or the filament bundle FB extruded by the spinning box 2 for automatic application to the winding device 14, they are preferably combined in the collection line 8 to form a filament bundle sliver FBS after being applied to the converging filament guides 22.

[0116] For this purpose, the filament bundle FB clamped by the converging filament guide 22 must be fed into the collecting line 8.

[0117] The collecting line 8 is arranged near the feed well 16 with its collecting line opening 6 in the corner region of the feed well and is in the open position as Figure 3 shown. The collecting line 8 is open. This can be seen from the fact that the first line part 8.1 is spaced apart from the second line part 8.2, thus providing an access opening for the filament bundle strand FBS.

[0118] The first line part 8.1 and the second line part 8.2 are pivotally interconnected by a hinge joint 9.

[0119] In Figure 3 , the filament bundles FF bundled and combined in the cooling well device have been incorporated from the collecting position through the converging filament guide 22 in the extension direction ER of the converging support 22 into the first feeding position ZP1 and are positioned adjacent to each other laterally in such a way that the filament bundle FB can be combined into the feed well in the collecting line 8 to form the filament bundle strand FBS.

[0120] Figure 3 The first feeding position ZP1 of the converging filament guide 22 on the converging support 21 is shown. The filament bundle FB has been fed into the collecting line 8 as the filament bundle strand FBS. The collecting line 8 is in the closed position GP as shown, in which the first line part 8.1 and the second line part 8.2 are combined in such a way that the collecting line 8 has a closed cross-section and the filament bundle strand can be pneumatically conveyed by the supply of compressed air at the collecting line opening 6 to the winding device 14.

[0121] As can be further seen from Figure 3 , the collecting line 8 has a much smaller cross-section than the feed well 4. The cross-section of the collecting line 8 allows the pneumatic conveyance and supply of compressed air, which facilitates, improves and accelerates the conveyance of the filament bundle strand FBS to the winding device.

[0122] It can be further seen from Figure 2 and Figure 3 that the converging filament guide 22 on the converging support 21 can move back and forth in the extension direction ER of the converging support 21, which is indicated by the double arrow with the reference sign ER.

[0123] According to the invention, the movement takes place by means of a drive device which can displace the converging filament guide 22 to the collecting position SP and the first feeding position ZP1.

[0124] Therefore, the drive device (not shown) is also adjusted such that the converging filament guide 22 can be displaced back from the first feeding position ZP1 to the collecting position SP.

[0125] The drive device can also be configured such that the converging filament guide 22 can be automatically and movably displaced along the converging support 21 to other positions.

[0126] Figures 4 to 6 Another embodiment of a cooling well device for combining by means of a converging filament guide 22 on a converging support 21 according to the invention is shown.

[0127] In Figure 4 the cooling well device further has a cutting device 26 which can be displaced in the extending direction ER of the converging support 21 by means of a cutting device support 28.

[0128] In Figure 4 the filaments FF are combined into a filament bundle FB by means of the converging filament guide 22 in the collecting position SP respectively.

[0129] If, for example, a fiber break has occurred on the creel device 14 below the feed well 4, the filaments FF can and need to be severed and resupplied. This can be done on the one hand on the creel device 14 and on the other hand also by means of the cooling well device according to the invention in the cooling well 3.

[0130] For this purpose, as Figure 5 shown, the converging filament guide 22 is displaced along the converging support 21 from the collecting position SP to the cutting position SCP. At the cutting position SCP, the cutting machine 26 can then act. At the cutting position SCP, the converging filament guides 22 are in place adjacent to one another, so that the cutting machine 26 can sever the bundled filaments FF with the help of the converging filament guides 22.

[0131] In order to dispose of the filaments FF which have been severed by the cutting device 26, a suction gun 24 for sucking the filaments FF and capable of guiding them to a waste filament collecting box 40 is provided close to and / or adjacent to the cutting device 26 ( Figure 10 ).

[0132] Figures 7 to 10 Another embodiment of a cooling well device according to the invention is shown.

[0133] In this embodiment, the cooling well device has a pivotable converging filament guide 22 which can be pivoted from the collecting position SP to a second feed position ZP2. In the collecting position SP, the guiding part 23 of the converging filament guide 22 faces the spinning box 2, and in the second feed position ZP2, the guiding part 23 of the converging filament guide 22 faces the feed well inlet 16, just as, for example, in Figure 9 and Figure 10 shown.

[0134] In this embodiment, the converging filament guide 22 is pivotally mounted on the converging support 21. Additionally or alternatively, the converging filament guide 22 can also be displaced to the first feeding position ZP1 for collection and to the cutting position SCP for cutting.

[0135] In Figures 7 to 10 , the filament capture funnel 30 is arranged to position the fiber bundle FB in the feeding position.

[0136] The filament capture funnel 30 has a conical configuration and is divided into a plurality of channels 38 which merge in the channel outlet 39 so that the collected filaments FF can be discharged together via the channel outlet 39 and the suction mechanism 36.

[0137] In the starting position STP, the filament capture funnel 30 collects the filaments FF and guides them to the converging support 21 and into the converging filament guide 22 so that the filaments FF can be combined to form a filament bundle FB.

[0138] Furthermore, the function of the filament capture funnel 30 is to combine the filament bundles FB to form filament bundle strands FBS so that they can be fed to the winding device 14 through the feed well 4. The filament capture funnel 30 is configured in a funnel shape and includes a funnel 34.

[0139] The shape of the funnel 34 facilitates the combination of the filaments into a filament bundle at the converging filament guide 22.

[0140] The filament capture funnel 30 can be displaced between the collection position and the feeding position along and against the filament path FLR adjacent to or near the spinning box, as indicated in Figure 7 and Figure 8 . The converging filament guide 22 is respectively arranged in the collection position in this case, and the guide portion 23 faces the spinning box 2 in the collection position.

[0141] The filament capture funnel 30 is in the starting position STP as shown in Figure 1.1 and Figure 1.2 , so that the filament capture funnel 30 can directly receive the filaments FF.

[0142] The received filaments FF are bundled through the channels 38 and collected, for example, into the waste filament collection box 40 as shown in Figure 10 by the suction mechanism 36 away from the filament capture funnel 30.

[0143] In the starting position of the filament capture funnel 30, the converging filament guide 22 is arranged in the collection position with its guide portion 23 facing the spinning box 2.

[0144] In Figure 8 , the filament capture funnel 30 is displaced to the feeding position ZP next to the feed well inlet 16.

[0145] In Figure 9 this case, the converging filament guide 22 has been pivoted to the second feed position ZP2. The collected filament bundle FB or filament bundle sliver can then be fed to the winding device 14 by means of the suction means 36.

[0146] Figure 9 and Figure 10 shows the situation where the converging filament guide 22 is in the second feed position ZP2, such that the filament bundle FB can be fed accordingly to the filament capture funnel 30 and can be fed to the winding device 14 via the channel outlet 39.

[0147] Furthermore, a cutting device 26 can be provided on the filament capture funnel 30, which acts at the entrance of the channel 38 and is displaced together with the filament capture funnel, as can be seen in the co - research Figures 7 to 10 as shown.

[0148] The cutting device 26 can be displaced on the cutting device support 28 such that the cutting device 26 can be displaced along the channel 38 in such a way that the filament bundles combined in the channel 38 can be successively severed.

[0149] Now a new filament bundle from the spinning box can be fed directly to the waste filament collection box 40 via the filament capture funnel and the suction means 36.
