Abstract

PROBLEM TO BE SOLVED: To surely avoid the contact of a member of an empty package frame regardless of the type of a winding tube to be used in each case.SOLUTION: A locking means (13) works to give a gap from a drive roller to a winding tube storing part (3). The means includes a spacer (9) confined and movably disposed in a package frame and a fastening device (13) working with the spacer (9) in which the spacer (9) is supported by a fixed part of a working part at a locking position. When there is no winding tube (2'), the package frame (1) is automatically held by a locking metal thin plate with a locking pin with a gap against the drive roller regardless of the type of the winding tube in use. In this case, no adjustment takes place in the package frame of a machine.

Description

  The present invention relates to a winding device used at a work site of a textile machine for manufacturing a traverse package, the winding device including a package frame for holding the traverse package, and the winding tube of the traverse package includes: The winding device is tightened between the winding tube accommodating portions of the package frame during the winding operation, and the winding device further includes means for traversing the yarn to be wound, and a driving roller for driving the traverse winding package by a frictional force. One winding tube accommodating portion is movable in the axial direction to an open position for inserting a new winding tube against the action of the pressing means, and the package frame has locking means, The lock means relates to a winding device used at a work site of a textile machine for manufacturing a traverse package, which acts to give a space from the drive roller to the winding tube housing portion. .

  Textile machines that produce traverse packages are winders and spinning machines, such as open-end spinning machines. Winders and spinning machines have been known for a long time and have been described in detail in numerous rights protection applications, usually having multiple working points of the same type arranged in a row next to each other. Yes.

  At the work site of an automatic winder, usually a plurality of spinning cups with relatively little yarn material are rewound to produce a high capacity traverse package required by subsequent textile machines, such as looms, in the manufacturing process. Form.

  The traversing package is placed on a driving roller and is driven by a frictional force by the driving roller, that is, rotated. If the drive roller is formed as a grooved roller, this drive roller further takes over the guide of the yarn to be wound. In contrast, if a drum without grooves is used as the drive roller, the yarn guide is guaranteed by a separate yarn guide, for example a finger yarn guide.

  The individual work points of the open-end spinning machine each have a spinning and winding device. In this spinning and winding device, the sliver stored in the spinning cannula is spun and wound up to form a traverse winding package.

  After the traversed package is taken out, the axially movable winding tube accommodating portion is moved by the pressing means until it reaches its end stopper. The wound tube housing portion includes a so-called wound tube housing plate. This winding tube accommodation plate is rotatably supported and is exchanged corresponding to various winding tube forms. When the countermeasure is not taken, the package frame itself descends based on its own weight. In this case, the package frame is placed on the driving roller in the moved winding tube accommodating portion, and in particular, the driving roller is erroneous. Lowers enough to be damaged at start-up.

  The instruction manual of Oerlikon Schlahorst, Autoconer X5, April 2012, version V3.0, which forms the closest solution of the known prior art, describes the current method of avoiding damage. In order to prevent the winding tube housing from being placed on the drive roller, two adjustable limiting elements are provided. That is, an adjustment screw that restricts the descent of the entire package frame and an abutment ring that restricts the travel of the movable winding tube housing.

  For this purpose, when the winding tube is inserted, the two screws must be loosened, so that the winding tube is placed on the drive roller or travel ring. After the screw has been tightened again, one stopper screw has to be screwed into the package frame and finally the nut. In this case, when the package frame is lowered, the right-hand winding tube accommodating portion does not come into contact with the driving roller. In order to check play, it is ensured that the windings are reliably connected when the drive roller is started.

  For this purpose, the winding tube is replaced by a gauge and the stopper metal sheet is applied against the cam of the package frame release lever by loosening another screw, and finally locked by tightening the screw. . The distance thus adjusted between the stopper and the cam must be in the range of 0.5 mm to 1.0 mm.

  The disadvantage of this method is that both adjustments depend on the geometry of the supplied winding tube and must therefore always be repeated and renewed. That is, on the one hand, it is necessary to make these adjustments every time the winding tube type is changed in order to prevent the winding tube housing portion from being placed on the driving roller and, on the other hand, to limit the travel of the movable winding tube housing portion. There is. Furthermore, these adjustments need to be performed very accurately based on the geometrical arrangement, and are therefore very time consuming and often require post-adjustment.

  This method not only adversely affects the productivity of the winder or spinning machine, but also causes the possibility of damage to the drive roller or the winding tube housing due to inaccurate adjustment.

Instruction manual for Oerlikon Schlahorst, AutoconerX5, April 2012, V3.0

  Starting from the above-mentioned known prior art, the problem underlying the present invention is to ensure avoidance of contact of the components of the empty package frame, irrespective of the winding tube type used each time. In this case, it is desirable not only to simplify handling, thereby ultimately increasing the productivity of the winding process, but also to reduce potential error sources.

  In the configuration according to claim 1 of the present invention that solves the above-described problem, the winding device is used at a work site of a textile machine that manufactures a traverse winding package, and the winding device holds the traverse winding package. A package frame, wherein the winding tube of the traverse package is fastened between the winding tube accommodating portions of the package frame during the winding operation, and the winding device further includes means for traversing the yarn to be wound; A winding roller that drives the traverse package by frictional force, and one winding tube housing portion can move axially to an open position for inserting a new winding tube against the action of the pressing means The package frame has a locking means, and the locking means is a winding device that acts to give a space from the driving roller to the winding tube housing portion. It is formed by a spacer which is confined and movably arranged in the package frame, and a clamping device which cooperates with the spacer, so that the spacer is supported by a fixed portion of the work location in a locked position. did.

  Advantageous embodiments of the present invention are described in claims 2 and below.

  In order to solve the above-mentioned problem, according to claim 1, the locking means is formed by a spacer that is movably disposed in a limited manner within the package frame, and a tightening device that cooperates with the spacer. The spacer is supported by the fixed portion of the work location at the locked position. With this arrangement, in the absence of the winding tube, the package frame is maintained at a distance (distance) from the drive roller by the clamped spacers automatically and independently of the winding tube type used. If this is the case, no preadjustment is carried out on the machine for this purpose. That is, since the spacer is locked by the tightening device, the winding tube housing portion cannot contact the drive roller.

  Preferably, as defined in claim 2, the clamping device is adapted to clamp the spacer when the winding tube is not inserted, thereby fixing the spacer in its immediate position. The device is arranged and loaded by pressing means. That is, when there is no winding tube, the pressing means acts on the tightening device, and the tightening device locks the spacer.

  According to the third aspect, the spacer is movably supported in the base body of the package frame, whereas the fastening device is fixed to a package frame release lever that is pivotally supported by the base body. The package frame release lever is connected to a winding tube accommodating portion that is movable in the axial direction and is loaded by a pressing means. By the movable support of the spacer in the substrate of the package frame and the temporary release of the spacer by the clamping device arranged on the package frame release lever, which is performed when the package frame is opened via the package frame release lever, Providing the package frame with a distance to the drive roller is guaranteed without any manual adjustment. That is, the tightening device attached to the package frame release lever locks the spacer by obtaining a tightening force to the spacer by the pressing means of the package frame when the package frame is empty and when the package frame release lever is released. Therefore, the spacer supports the package frame at the fixed portion of the work location. The spacer is dimensioned so that the distance between the drive roller and the winding tube storage portion is sufficient for providing a space even when a very large winding tube storage plate is used. Thus, the need for adjustment is eliminated even in the case of extreme tube types.

  According to a fourth aspect of the present invention, it is advantageous that the spacer and the tightening device are arranged and formed so that the end position of the movable winding tube accommodating portion does not intersect the driving roller. In other words, the tightening device restricts the maximum stroke of the winding tube housing portion, and thereby restricts the path of the winding tube housing portion that can move in the axial direction.

  As described in claim 5, the spacer comprises a drop pin. The drop pin is slidably supported and axially movable so that simple handling can be ensured without having to make adjustments in the package frame.

  According to the variation of the winding device according to the sixth aspect of the present invention, the tightening device is formed of a lock metal thin plate. Such a lock metal thin plate can be produced in large quantities without much effort in terms of manufacturing technology.

  Furthermore, as described in claim 7, the pressing means may be a spring. The spring as a mechanical element can be constructed maintenance-free and simply. The clamping force exerted by the spring force is sufficient to hold the package frame in place and prevent it from descending towards the drive roller. Instead of a spring, the clamping force can also be generated, for example, electromagnetically.

  According to the aspects described in claims 8, 9 and 10 of the present invention, the drop pin has the stopper means for limiting the axial movement distance. In order to prevent the drop pin from falling off when the traverse package is taken out, the drop pin is fixed in position against the drop by an O-ring above. The O-ring is made from a flexible material and does not cause additional noise during operation. Since the drop pin is fixed with respect to the drop-off by the end cap on the side positioned below in the assembling direction, for example, the drop pin cannot be mistakenly dropped from the guide portion during the reassembly work in the package frame.

  According to claim 11, the drop pin has one or more radial grooves. By this recessed portion, a shape connecting portion, that is, a connecting portion based on the shape is formed between the drop pin and the lock metal thin plate, so that the package frame can be reliably held at a spaced position. As a result, additional pressure acts on the package frame, and even when the package frame is lowered, the winding tube housing portion is prevented from coming into contact with the drive roller.

  The invention is explained in more detail below with reference to exemplary embodiments shown in the drawings.

It is the schematic of a package frame. It is the schematic of the package frame provided with the traverse package. FIG. 2 is a detailed view showing an apparatus according to the present invention without a winding tube. FIG. 2 is a detailed view showing an apparatus according to the present invention without a winding tube. It is a figure which shows the support part of the drop pin in the base | substrate of a package frame.

  1 and 2 show schematic views of a package frame 1 of the winding device. In such a type of winding device, the yarn is wound up to form the traverse package 2. The traverse winding package 2 is held in the package frame 1 by the winding tube 2 'during the spinning process or the winding process. In this case, for example, a yarn guide drum is provided via the package driving roller 8 in this embodiment. Via the frictional force. In addition to driving, the yarn guide drum 8 acts so that the package 2 is wound up while being traversed. The package frame 1 is supported so as to be pivotable about the pivot axis 6.

  Furthermore, this type of package frame 1 has a winding tube housing portion 3 provided with a winding tube housing plate 4 as a whole. The winding tube 2 ′ is tightened between the winding tube accommodation plates 4. By means of the package frame release lever 5, the winding tube housing part 3 located on the right side when viewed from the front is moved in the axial direction, so that the winding tube 2 ′ of the traverse package 2 can be inserted. it can.

  3 and 4 are detailed views of the apparatus according to the present invention. In this case, the winding package 2 or the winding tube 2 'is not inserted. A drop pin 9 functioning as a spacer is slidably supported on one arm of the package frame 1 and is freely movable along its axis. A lock metal thin plate (Sperrblech) 13 acting as a tightening device (Klemmvorrichtung) is applied to the drop pin 9 on the arm of the package frame 1. A clamping force transmitted to the package frame release lever 5 is formed by the pressing spring (Spannfeder) 14. The drop pin 9 is fixed in the axial direction by the O-ring 10 at the upper position in the assembling position. In this case, the movement in the vertical direction is restricted without the action of the lock metal thin plate 13. Below the assembling direction, this vertical movement limitation is guaranteed by the end cap 11. The one or more grooves 12 ensure additional retention based on the shape connection type of the drop pin 9 in the lock metal sheet 13, that is, based on shape constraints.

  FIG. 5 shows a support portion for the drop pin 9 in the base body of the package frame 1.

  The traverse package 2 can be taken out of the package frame 1 by operating the package frame release lever 5 toward the right against the force of the pressing spring 14. The drop pin 9 falls down to the O-ring 10 and is placed on the winding unit casing 7. Next, the movable winding tube accommodating portion 3 moves toward the left side by the action of the pressing spring 14 and is tightened in the radial direction by the lock metal thin plate 13. This tightening force is transmitted from the pressing spring 14 of the winding tube housing 3 to the package frame release lever 5 to which the lock metal thin plate 13 is attached via the joint 15. In this case, the spring force and the lever ratio are sufficient for the clamping force acting on the drop pin to hold the drop pin 9 and thus the package frame 1 in that position and prevent it from dropping towards the yarn guide drum 8. There is to be.

  The lock metal thin plate 13 applied to the drop pin 9 limits the maximum stroke of the movable winding tube housing 3. When pressure is applied to the spaced apart package frame 1, the drop pin 9 is captured by the radial groove 12 provided in the drop pin 9 and forms a shape connection with the lock metal thin plate 13. 12 additionally protects the spacing.

  When a new winding tube 2 ′ is inserted into the package frame 1, the movable winding tube accommodating portion 3 moves further to the right along the axis thereof, and the pressing spring 14 moves the winding tube 2 ′. Tightening, the lock metal sheet 13 releases the drop pin 9. The drop pin 9 is now movable again in the axial direction and the package frame 1 or the winding tube 2 ′ can be placed on the yarn guide drum 8. In this case, the drop pin 9 does not limit the required turning path. Since the package frame 1 is supported exclusively by the winding tube 2 'or the traverse package 2 at the winding position, an accurate frictional connection naturally occurs.

  Therefore, regardless of the package type, when the package frame 1 is empty, the reliable interval of the winding tube receiving plate 4 from the driving roller 8, the winding tube 2 ′ or the traverse winding package 2, and the driving roller 8. It can be seen that the optimum frictional connection for the package type is given between

The traverse package 2 can be taken out of the package frame 1 by operating the package frame release lever 5 toward the right against the force of the pressing spring 14. The drop pin 9 falls down to the O-ring 10 and is placed on the winding unit casing 7. Next, the movable winding tube accommodating portion 3 moves toward the left side by the action of the pressing spring 14, and the drop pin 9 is fastened in the radial direction by the lock metal thin plate 13. This tightening force is transmitted from the pressing spring 14 of the winding tube housing 3 to the package frame release lever 5 to which the lock metal thin plate 13 is attached via the joint 15. In this case, the spring force and the lever ratio are sufficient for the clamping force acting on the drop pin to hold the drop pin 9 and thus the package frame 1 in that position and prevent it from dropping towards the yarn guide drum 8. There is to be.

The lock metal thin plate 13 applied to the drop pin 9 limits the maximum stroke of the movable winding tube housing 3. When a pressure in the direction of the yarn guide drum 8 is applied to the spaced apart package frame 1, the drop pin 9 is captured by the radial groove 12 provided in the drop pin 9 to form a shape with the lock metal thin plate 13. Since the connection is formed, the groove 12 additionally protects the spacing.
