Description

Technical Field

[0001] The utility model relates to a winding device, in particular to a winding device with multiple winding positions. Background Art

[0002] The winding equipment is composed of a plurality of winding modules of the same structure, each of which is called a "winding station".

[0003] A similar winding station is disclosed in the known patent document with publication number CN101124138B. A reciprocating device is arranged in front of the friction roller. The reciprocating device is constructed as a belt-type reciprocating device. The reciprocating yarn guide is fixed on a continuous belt. The belt is guided parallel to the bobbin between two deflection wheels. A driving wheel parallel to the deflection wheel is also provided. The driving wheel is driven by a motor in an oscillating manner, so that the reciprocating yarn guide is reciprocated in the area between the two deflection wheels.

[0004] In the patent document, the reciprocating device is located on the side of the friction roller close to the operating side. The operator uses this "side" to spin the yarn or perform maintenance on the winding position.

[0005] With the design trend of accommodating as many winding positions as possible in one machine, the size of winding equipment has become larger and larger, and the two most important size indicators are the width and height of the winding equipment.

[0006] Under the existing mechanical structure, the height between winding layers cannot be reduced, which means that the increase in the number of layers will lead to a proportional increase in the height of the entire winding equipment. Whether it is maintenance or threading of the top winding position, it faces the adverse effects of the increased size. At the same time, the excessive width of the winding equipment also brings inconvenience to maintenance and threading operations. Utility Model Content

[0007] In order to suppress the expansion of the overall width and height of the winding device while increasing the number of winding positions as much as possible, the utility model proposes the following solution, thereby eliminating the negative impact of the size expansion on maintenance and threading.

[0008] According to the first aspect of the utility model, a winding device having a plurality of winding positions is provided, wherein the plurality of winding positions are arranged in a manner of vertical multi-layer stacking and horizontal side-by-side arrangement, and each winding position has a cradle unit with clamping disks provided at opposite ends, a belt-type reciprocating guide unit for laterally guiding the filament, and a friction roller unit, wherein the belt-type reciprocating guide unit comprises a driving wheel, a steering wheel, a belt element tensioned by the driving wheel and the steering wheel, a guiding element arranged on the belt element, and a driving unit for driving the driving wheel, wherein, taking the plumb line where the guiding element is located as a reference, the belt element and the driving unit are located on the side of the plumb line away from the operating side.

[0009] By arranging the belt-type reciprocating guide unit on the other side of the vertical line where the guide element is located, away from the operating side, the transverse width of the winding device is significantly reduced.

[0010] According to a second aspect of the utility model, the belt element is arranged in a manner of surrounding the friction roller unit through the driving wheel and a plurality of the steering wheels. In order to avoid interference with the friction roller unit, the belt element and other elements are arranged in this way.

[0011] According to a third aspect of the present utility model, the guiding element and the driving portion are located on different sides of a vertical line where the rotation center of the friction roller unit is located.

[0012] In order to further reduce the lateral space occupied by each winding position, according to a fourth aspect of the utility model, the winding position of each layer has an electrical box unit, which is closer to the operating side relative to the guiding element, and the electrical box unit is arranged along the vertical direction.

[0013] Even though the electrical box will occupy more space vertically after being arranged vertically, since the distance between the operating side and the cradle unit is significantly reduced, the distance between the lower surface of the electrical box unit at one winding position and the bobbin-dropping auxiliary unit at the adjacent next winding position is sufficient for the operator to spin the yarn.

[0014] According to the fifth aspect of the utility model, a doffing auxiliary unit having a rotatable wire suction tube is arranged at a position closer to the operating side relative to the friction roller, and the wire suction tubes of the doffing auxiliary units at the winding positions in the same column are all connected to the same vertically arranged waste wire tube, and the waste wire tube is connected to the waste wire box.

[0015] In order to further reduce the lateral space occupied by each winding position, according to a sixth aspect of the utility model, the bobbin-dropping auxiliary unit is partially integrated in the electrical box unit.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] Textile machinery uses winding equipment to wind filaments or yarns. The filaments are wound on the winding tube in a cross-winding manner. The reciprocating guide unit is an indispensable component for achieving cross-winding.

[0026] There are two construction modes of the current reciprocating guide unit, one is the grooved drum type and the other is the belt type.

[0027] The basic structure and working principle of the grooved drum reciprocating guide unit belong to the prior art, so only a general description is given here. The grooved drum reciprocating guide unit mainly consists of a cylinder with grooves on the surface, a shuttle sliding in the grooves, and a track that restricts the shuttle from moving linearly. The cylinder driven to rotate by a driving source causes the shuttle to reciprocate in the track. The guide element is installed on the shuttle.

[0028] The belt-type reciprocating guide unit relies on a driving wheel directly driven by a driving part, a steering wheel installed parallel to the driving shaft, a belt element partially sleeved on the driving wheel and the steering wheel, and a guiding element installed on the belt element to achieve the reciprocating motion of the guiding element. The structure of the belt-type reciprocating guide unit will be described in detail later in this application.

[0029] Figure 1 The structure diagram of the winding device according to the utility model is shown in FIG. The winding device is a collection of multiple winding positions. Multiple winding positions are stacked vertically in multiple layers and arranged in multiple rows in parallel longitudinally. Referring to the perspective of the attached figure, direction A is the width direction and direction B is the vertical direction. Figure 1 In the embodiment, the winding device comprises four layers of winding positions, and the winding positions 1, 2, 3, and 4 are shown in each layer as examples, and the structure of each winding position is basically the same. Therefore, only the winding position 1 is taken as an example to explain its structure.

[0030] The function of the cradle unit 1.1 is to provide a mechanism that can clamp the winding tube and thus the filament bobbin. One end of the mechanism has a pair of opposite clamping parts 1.2, and the other end has a rotating shaft 1.13. Driven by the cylinder, the cradle unit 1.1 can rotate around its rotating shaft 1.13 at a certain angle, so that the winding tube clamped by the clamping part 1.2 can contact or move away from the friction roller unit 1.4 located at the lower left of the cradle unit 1.1. The cylindrical friction roller unit 1.4 is fixedly installed horizontally. The winding tube pressed on the friction roller unit 1.4 rotates together with the friction roller unit 1.4 that is directly driven to rotate. After the filament is introduced into the winding position 1, it is wound on the winding tube to form a filament bobbin 1.3.

[0031] The bobbin forming process requires that the filaments be wound in the form of a cross angle. The belt-type reciprocating guide unit 1.5 makes this possible. As the winding time goes by, the diameter of the filament bobbin 1.3 gradually increases. The cradle unit 1.1 rotates clockwise.

[0032] After the filament bobbin 1.3 is fully wound, the control unit identifies the fully wound state of the bobbin and sends a signal to open a pair of clamping parts 1.2. The fully wound filament bobbin 1.9 is released by the clamping part 1.2, falls on the fully wound track 1.12 directly below it, and rolls along the slope of the fully wound track 1.12, and finally stops at a predetermined position. Generally, the fully wound track 1.12 can accommodate 2-4 fully wound bobbins. After observing that the fully wound track 1.12 is full, the operator takes out multiple fully wound bobbins 1.9 one by one.

[0033] A winding tube warehouse 1.7 is installed above the full-winding track 1.12, which contains a plurality of empty winding tubes 1.8. The function of the winding tube warehouse 1.7 is to provide a new winding tube 1.8 to the cradle unit 1.1 to replace the previously released full-winding filament bobbin. One implementation method is that when the cradle unit 1.1 is at the highest position, a pair of clamping parts 1.2 are very close to the outlet of the winding tube warehouse 1.7, and the first winding tube in the winding tube warehouse 1.7 is released, falls between the pair of clamping parts 1.2 and is clamped. This method places high requirements on the vertical height of each winding position. As another method with lower requirements on the vertical height of the winding position, the winding tube warehouse 1.7 is configured to be movable in the direction of the clamping part 1.2. In this case, the cradle unit 1.1 is not required to rotate a large angle, and the winding tube warehouse 1.7 actively moves to a position close to the clamping part 1.2 only after it rotates a small angle. According to the disclosure of the prior art, the winding tube bin 1.7 can achieve the above-mentioned movement by means of gear transmission or cylinder pushing.

[0034] Each winding position 1-4 is equipped with a doffing auxiliary unit 1.11, which usually has a cutting element, a suction element and a rotating mechanism driven by a drive motor 1.6. The cutting element cuts the full bobbin and the continuously supplied filaments, the suction element sucks the ends of the cut filaments, and the rotating action of the rotating mechanism enables the sucked filaments to be transferred to the guide unit. In the well-known automatic doffing machine, the doffing auxiliary unit 1.11 assists the automatic doffing process.

[0035] Figure 1 The marked 6 is the operating side, and the operator stands on this side facing the winding device and holds a suction gun to perform the spinning operation. The spinning operation is that the operator holds the suction gun that sucks the end of the filament and delivers the filament to the vicinity of the doffing auxiliary unit 1.11, so that the suction element of the doffing auxiliary unit 1.11 sucks the filament. In this embodiment, the belt reciprocating guide unit 1.5 can also be maintained through the operating side 6, such as replacing the belt, motor, etc.

[0036] Also in Figure 1 The side opposite to the operator's operating side 6 is shown as the take-out side 11. The operator takes out several full rolls 1.9 from the full roll track 1.12 through this side, so that the next full rolls that have been wound can fall onto the full roll track 1.12 without interruption to be temporarily stored.

[0037] In order to reduce the transverse width of the winding device in direction A, the belt reciprocating guide unit 1.5 is arranged as follows, with the plumb line where the guide element is located as a reference, the left side of the plumb line is the operating side, which provides space for the operator to operate the threading. The right side of the plumb line 7 is the side opposite to the operating side 6. The belt element 10 and the drive unit 1.14 are located on the side of the plumb line 7 opposite to the operating side 6. Correspondingly, the belt element 10 is installed in a manner of surrounding the friction roller unit 1.4, and the drive unit 1.14 is further located below the cradle unit 1.1.

[0038] even though Figure 1 The schematic diagram shows that the belt-type reciprocating guide unit 1.5 is installed in a nearly horizontal direction, but the present application is not limited to this. The belt-type reciprocating guide unit 1.5 can also be installed at a larger inclination angle, which will be described later.

[0039] Figure 2 Schematic illustration Figure 1 A top view of the friction roller unit and the belt-type reciprocating guide unit according to the embodiment.

[0040] The driving shaft of the driving part not shown in this view is directly connected to the driving wheel 9, and the driving wheel 9 is directly driven to rotate. The belt-type reciprocating guide unit is further provided with four deflection wheels 8.1-8.4 installed along the periphery of the friction roller unit 1.4 in a manner parallel to the driving wheel 9. The belt element 10 is simultaneously mounted on the driving wheel 9 and the deflection wheels 8.1-8.4, so that the driving wheel 9 and the deflection wheels 8.1-8.4 can rotate simultaneously. The belt element 10 is arranged around the friction roller unit 1.4.

[0041] The first section 10.1 of the belt element 10 is formed between the steering wheel 8.1 and the steering wheel 8.4, close to the circumferential surface of the friction roller unit 1.4 and parallel to the axial direction of the friction roller unit 1.4. The second section 10.2 is formed between the steering wheel 8.1 and the steering wheel 8.2, and the third section 10.3 parallel to the second section 10.2 is formed between the steering wheel 8.4 and the steering wheel 8.3. The second section 10.2 and the third section 10.3 are close to the end surface of the friction roller 1.4 and perpendicular to the axial direction of the friction roller unit 1.4. The guide element 12 is fixed on the first section 10.1. Under the control of the controller, the driving part alternately changes the rotation direction at high frequency to make the guide element 12 reciprocate along the axial direction of the friction roller unit 1.4. The stroke of the guide element 12 determines the length of the wound filament bobbin.

[0042] Figure 3 for Figure 1 The following embodiment shows only the side view of the friction roller unit and the belt-type reciprocating guide unit.

[0043] In order to utilize the existing idle space, the drive unit 1.14 is installed nearly horizontally, and the output shaft 1.15 of the drive unit 1.14 is arranged upward. The drive wheel 9 is arranged on the free end of the output shaft 1.15, and the steering wheels 8.1, 8.2, and two other steering wheels not shown in this perspective are freely rotatably arranged on the upper surface of the base part 1.16. The belt element 10 surrounds the upper half of the friction roller unit 1.4. The plumb line where the guide element 12 is located is marked as 7, and the left side thereof is the operating side 6. The drive wheel 9, the belt element 10 and the drive unit 1.14 are located on the right side of the plumb line 7. The beneficial effect brought about is that the width of the winding device between the operating side 6 and the removal side 11 can be significantly compressed compared with the prior art.

[0044] Further Figure 3 As shown, a vertical line passing through the rotation center of the friction roller unit 1.4 is marked with 5. The guide element 12 and the drive part 1.14 are located on both sides of the vertical line 5.

[0045] Figure 4 A schematic diagram of a winding device according to another embodiment.

[0046] The winding device in this embodiment is a manual type. Figure 1The difference between the embodiments is that the replacement of the full roll bobbin is performed by the operator. After the bobbin reaches the predetermined diameter size or the full roll size, the operator needs to immediately remove the full roll bobbin and install the empty winding tube. The cradle units 1.2, 1.3, 1.4, 1.5 are rotatably arranged on the wall panels 14.1, 14.2, 14.3, 14.4 respectively. There is no space for the operator to stand on the left side of the wall panels 14.1-14.4. The operating side and the removal side are on the same side, located on the right side of the winding device, marked by 13. On this side 13, in addition to the operations of removing the full roll and installing the empty tube, the operator also performs the head-spinning operation. The belt element of the belt reciprocating guide unit 1.5 is arranged in a manner to surround the lower half of the friction roller unit. A recess 15.1, 15.2, 15.3, 15.4 is provided on one side of each wall panel portion 14.1, 14.2, 14.3, 14.4, respectively, to provide an installation space for the driving portion of the belt-type reciprocating guide unit 1.5.

[0047] Figure 5 for Figure 4 The illustrated embodiment only shows a side view of the friction roller unit and the belt-type reciprocating guide unit at one winding position.

[0048] Based on space considerations, the drive unit 1.14 is installed above the base unit 1.16, and the output shaft 1.15 directly connected to the drive unit 1.14 is installed downward. A drive wheel 9 is installed on the free end of the output shaft 1.15. Steering wheels 8.1, 8.2 and other steering wheels not shown are installed on the lower surface of the base unit 1.16. Taking the plumb line 7 where the guide unit 12 is located as a reference, the operation / removal side 13 is located on one side of the plumb line 7, and the drive unit 1.14 and the belt element 10 are located on the other side of the plumb line 7. In order to adapt to the spatial layout of the manual model, the belt reciprocating guide unit is inclined at a larger angle relative to the plumb line 7. The effect is that when the full roll of the lower winding position is taken out from the operation / removal side 13, it will not interfere with the belt reciprocating guide unit of the adjacent upper winding position.

[0049] according to Figure 1 As shown, an electrical box unit 16 is provided on the outer side of each winding position close to the operating side, which is used to accommodate the electrical components for controlling the bobbin-dropping auxiliary unit 1.11. In order to further reduce the width of the winding device in the A direction, the electrical box unit 16 is arranged in the vertical direction (direction B), and its internal electrical components are also arranged vertically accordingly, so as to reasonably utilize the internal space of the electrical box unit 16. Even though the electrical box unit 16 will occupy more space in the vertical direction (direction B) after being arranged vertically, since the distance between the operating side 6 and the cradle unit 1.1 is significantly reduced, the distance between the lower surface of the electrical box unit of one winding position and the bobbin-dropping auxiliary unit of the adjacent next winding position is sufficient for the operator to spin the yarn.

[0050] The doffing auxiliary unit 1.11 is partially integrated in the electrical box unit 16 , so the doffing auxiliary unit 1.11 no longer occupies space alone in direction A. To this end, at least the drive motor 1.6 and part of the wire suction tube 17 are accommodated in the electrical box unit 16 together.

[0051] When each winding position is performing the bobbin-dropping operation, the wire suction tube 17 will continue to suck the filament for a period of time, producing a section of filament that cannot be wound. Because it is waste silk, it needs to be collected uniformly. For this reason, a waste silk box 19 is provided below the winding position 4 at the bottom layer, which collects waste silk from each winding position. Connected to the waste silk box 19 is a waste silk tube 18, which is arranged vertically (direction B) and is respectively connected to the wire suction tube 17 of each winding position.

[0052] Before the filaments enter each winding position 1, 2, 3, 4, grease is applied centrally at the oiling unit 20. The oiling unit 20 is located at a height close to the lowest winding position.

[0053] The present application is described above in conjunction with specific embodiments, but it should be clear to those skilled in the art that these descriptions are exemplary and are not intended to limit the scope of protection of the present application. Those skilled in the art can make various modifications and variations to the present application based on the spirit and principles of the present application, and these modifications and variations are also within the scope of the present application.

Many features and advantages of these embodiments are clear from this detailed description, and therefore the appended claims are intended to cover all such features and advantages of these embodiments that fall within their true spirit and scope. In addition, since many modifications and changes are easily conceivable to those skilled in the art, the embodiments of the present application are not intended to be limited to the precise structures and operations illustrated and described, but all suitable modifications and equivalents that fall within their scope may be covered.
