Description

Technical Field

[0001] The present invention generally relates to the technical field of webbing winding equipment, and in particular to a mobile webbing multi-layer winding and unwinding vehicle. Background Art

[0002] Ribbon production requires multiple processes, including weaving, dyeing, printing, and shaping. In actual production, to improve production efficiency, facilitate storage, and enhance quality management, each process is divided into multiple production lines. Therefore, semi-finished ribbons need to be transferred between production lines. The existing transfer method is to place the ribbons woven by the weaving machine directly into a frame for transfer. However, the ribbons in the frame are messy and prone to twisting or knotting, making it difficult to feed them to the next process, directly affecting the production and product quality of subsequent processes such as dyeing. Therefore, it is necessary to upgrade and improve the ribbon transfer method. Using appropriate winding equipment to wind and organize the ribbons before transferring them is one of the more feasible methods.

[0003] At present, most winding equipment has a horizontal drum structure, which forms a covering layer by wrapping the webbing around the drum several times on the same radius, and repeating this process back and forth to form multiple layers to complete the winding. During the trial, it was found that although it can quickly complete the webbing winding, the webbing needs to move back and forth along the length of the drum during winding. Due to the structural characteristics of the webbing being flat and having a certain degree of stretchability, the winding posture of the webbing wound on the drum is generally and significantly skewed. Winding on the drum for a long time further aggravates the irreversibility of this deformation, making the webbing structure loose and the quality reduced. At the same time, when winding and unwinding, the webbing is repeatedly pulled diagonally, which can easily cause the local force on the webbing to be different, resulting in the overall deformation of the webbing, and the flatness and straightness of the webbing are reduced. Therefore, the existing horizontal winding equipment is not well suited for webbing winding.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0036] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without one or more of these details. In other instances, certain technical features well known in the art are not described to avoid confusion with the present invention.

[0037] Example 1

[0038] See also Figures 1 to 3 , schematically shows a structural diagram of a mobile multi-layer webbing winding and unwinding vehicle, which includes a frame assembly 1, on which at least two webbing winding units are provided, and the webbing winding unit includes a working platform 11, a winding device 2, a webbing guide device 3, and a layer full detection device 4.

[0039] See also Figure 1 and Figure 2 The winding device 2 includes a rotating table 20, a winding shaft 204, and a driving mechanism 21. The rotating table 20 is horizontally arranged on the working platform 11, and a first plane bearing 203 is provided between the rotating table 20 and the working platform 11; the winding shaft 204 is arranged on the central axis of the rotating table 20, and a driving mechanism 21 for driving the rotating table 20 to rotate is connected to the bottom of the rotating table 20.

[0040] See also Figure 2The webbing guide device 3 is used to guide the webbing to the winding device 2. The webbing guide device 3 includes a first lifting device 30 and a webbing guide mechanism 31. The first lifting device 30 is located on one side of the rotating platform 20, and the webbing guide mechanism 31 is located on the lifting portion of the first lifting device 30. The webbing guide mechanism 31 of the webbing guide device 3 is mounted on a mounting plate 33, which is fixedly connected to the lifting portion of the first lifting device 30. A webbing tension control device 5 is provided on one side extending from the mounting plate 33. In this embodiment, a manually adjustable tensioning pulley mechanism is used as the webbing tension control device 5.

[0041] See also Figure 2 The layer fullness detection device 4 is located on one side of the rotating platform 20. It is used to detect changes in the thickness of the ribbon layer and issue a layer fullness signal. Layer fullness detection can be performed as the ribbon guide mechanism 31 rises and falls, and can be detected using a distance sensor. The mounting plate 33 of the ribbon guide mechanism 31 is equipped with an arc-shaped extension plate 32 coaxial with the central axis of the rotating platform 20. The layer fullness detection device 4 is mounted on the arc-shaped extension plate 32.

[0042] The working process of the mobile webbing multi-layer winding and unwinding vehicle of this embodiment is as follows:

[0043] After passing through the webbing tension control device 5, the webbing guide device 3 guides the webbing to the reeling shaft 204 of the winding device 2 for winding. As the rotating platform 20 drives the reeling shaft 204 to rotate and rewind the webbing, the height of the webbing guide mechanism 31 of the webbing guide device 3 remains constant, allowing the webbing to be continuously wound on the first webbing layer at a fixed height on the reeling shaft 204. As the number of webbing turns increases, the thickness of the reeling layer increases. When the full layer detection device 4 detects that the reeling layer thickness reaches a set value, it issues a full layer signal. At this point, the winding device 2 shuts down manually or automatically upon receiving this signal. After shutting down, the first lifting device 30 is activated to drive the webbing guide mechanism 31 up to the height of the second webbing layer. The second lifting device 61 is activated to drive the full layer pressing device 6 to the height of the first webbing layer and press the pressing mechanism 62 onto the outermost circle of the first webbing layer. At this point, staff members use tools such as clips and tape to temporarily secure the outermost webbing of the first webbing layer, then activate reel 204 to reel in the second webbing layer. Repeating the reeling process for the first webbing layer completes the reeling process, and after repeating this process several times, a multi-layer webbing reeling structure is formed. After a certain number of turns of webbing are wound around the second webbing layer, staff members can remove the temporarily secured webbing. To unwind, simply pull the webbing upwards, and it will detach layer by layer in an orderly manner, eliminating the need to rotate reel 204. This prevents potential deformation of the webbing during unwinding, further ensuring product quality.

[0044] Example 2

[0045] See also Figures 4 to 7Although the equipment of Example 1 has a good webbing rewinding capability, it still requires a certain amount of manual assistance, and the rewinding efficiency still has a lot of room for improvement. Therefore, this embodiment provides a mobile webbing multi-layer rewinding and unwinding vehicle with a higher degree of automation to improve the rewinding efficiency of the equipment. Specifically, the difference between Example 2 and Example 1 is that in this embodiment, the rotating table 20 is provided with a stepped outer edge 205, and a layer full pressure belt device 6 is provided on the stepped outer edge 205, wherein the stepped outer edge 205 can lower the center of gravity, making the rotation more stable. Furthermore, another preferred embodiment can also provide a counterweight at a mirrored position of the layer full pressure belt device 6 centered on the rotation axis to balance the influence of centrifugal force on the rotating table 20.

[0046] See also Figure 7 The layer-full belt pressing device 6, shown as part A in the figure, comprises a second lifting device 61 and a belt pressing mechanism 62 for pressing the webbing roll surface. The belt pressing mechanism 62 comprises a connecting plate 621, an articulated seat 622, an articulated frame 623, a pressure roller 624, and an electric push rod 625. The articulated seat 622 is mounted on the connecting plate 621. One end of the articulated frame 623 is hinged to the articulated seat 622. The other end of the articulated frame 623 is provided with a pressure roller 624. The middle portion of the articulated frame 623 is hinged to the piston rod end of one end of the electric push rod 625. The other end of the electric push rod 625 is hinged to the connecting plate 621. The second lifting device 61 is located on one side of the rotating platform 20, and the belt pressing mechanism 62 is located in the lifting portion of the second lifting device 61. The second lifting device 61 includes an electric lifting screw. Since the belt pressing mechanism 62 is mainly used to replace manual temporary fixation of the webbing in the "first webbing layer", the belt pressing mechanism 62 must always be maintained at a lower height than the webbing guide mechanism 31. Only when the webbing guide mechanism 31 rises to begin winding the next layer of webbing does the belt pressing mechanism 62 push the webbing layer to temporarily fix it. Therefore, the cylinder of the electric lifting screw is fixed to the bottom surface of the step outer edge 205. When the electric lifting screw is in the retracted state, its upper end is at the lowest point relative to the step outer edge 205, ensuring that the electric lifting screw is within the working range at any extension length. The upper end of the electric lifting screw is provided with a lifting block 611, and the belt pressing mechanism 62 is fixed to the lifting block 611, that is, the connecting plate 621 is fixed to the lifting block 611. Lifting block 611 has sliding holes on either side, each containing a T-shaped guide rod 612. The lower end of guide rod 612 extends through outer edge 205 of step. As lifting block 611 is raised or lowered, guide rod 612 rises and slides synchronously along the sliding holes. Guide rod 612 supports lifting block 611, preventing deformation of lifting block 611 caused by the reaction force of pressure roller 624 of belt pressing mechanism 62 pressing the webbing layer, thereby improving the stability of the device.

[0047] See also Figure 5 and Figure 6A second plane bearing 206 is provided between the outer edge 205 of the step and the working platform 11. The driving mechanism 21 includes a driving motor 211 and a load-bearing shaft 222. The load-bearing shaft 222 is a hollow steel shaft. The load-bearing shaft 222 is passed through the working platform 11. A radial bearing 2223 is provided on the outer periphery of the load-bearing shaft 222 and the working platform 11. The upper part of the load-bearing shaft 222 is fixedly connected to the rotating table 20, and the lower part of the load-bearing shaft 222 is fixedly connected to a gear disk 213. The outer peripheral teeth of the gear disk 213 are engaged with the gear 212 provided on the output shaft of the driving motor 211 for transmission. A load-bearing edge 2221 is provided on the outer periphery of the load-bearing shaft 222, and a third plane bearing 2222 is provided between the load-bearing edge 2221 and the working platform 11.

[0048] See also Figure 5 and Figure 6 A wire groove 201 is provided on the bottom surface of the rotating table 20, and a conductive slip ring 202 is provided at the center axis position of the bottom surface of the rotating table 20. The wire at one end of the conductive slip ring 202 passes through the wire groove 201 and is connected to the layer full pressure belt device 6 for power supply, and the wire at the other end of the conductive slip ring 202 is led downward from the bearing shaft 222 and connected to the power supply.

[0049] See also Figure 4 and Figure 5 The webbing guide device 3 is provided on a bracket of the frame assembly 1, and the first lifting device 30 of the webbing guide device 3 is a screw lifting device. A turntable 70 is detachably connected to the rotating table 20, and the reel 204 is provided on the turntable 70 and coincides with the central axis of the rotating table 20. The detachable turntable 70 is convenient for replacing the reel 204 as needed, such as replacing the reel 204 with a different diameter as needed, thereby improving the flexibility and practicality of the device. In this embodiment, the detachable structure of the turntable 70 is that a plurality of connecting columns are provided on the bottom surface of the turntable 70, and a plurality of corresponding sockets are provided on the rotating table 20. During installation, the two are plugged in. In addition, the detachable structure of the turntable 70 can also be bolt-locked, buckled, or the like.

[0050] In order to better coordinate the operation of various devices and improve the automation level of the equipment, a control device is also provided in this embodiment. Specifically, the control device is electrically connected to the drive mechanism 21, the first lifting device 30, the layer fullness detection device 4, the second lifting device 61, and the electric push rod 625.

[0051] The working process of the mobile webbing multi-layer winding and unwinding vehicle of this embodiment is as follows:

[0052] After the webbing passes through the webbing tension control device 5, the webbing is guided by the webbing guide device 3 to the winding shaft 204 of the winding device 2 for winding. The driving mechanism 21 is started by the control device, and the driving mechanism 21 drives the rotating table 20. The winding shaft 204 on the rotating table 20 rotates accordingly. At this time, since the head end of the webbing guided by the webbing guide device 3 has been pre-fixed at the lower part of the winding shaft 204, the rotation of the winding shaft 204 will rewind the webbing.

[0053] Specifically, the height of the webbing guide mechanism 31 of the webbing guide device 3 remains unchanged, so that the webbing is continuously wound on a fixed height of the winding shaft 204, that is, the first webbing layer. As the number of webbing turns increases, the thickness of the winding layer increases continuously. When the layer full detection device 4 detects that the layer thickness reaches the first set value, it sends a layer full signal to the control device.

[0054] At this time, the control device controls the first lifting device 30 to start according to a pre-set program, raising the webbing guide mechanism 31 to the height of the second webbing layer. At the same time, the control device controls the second lifting device 61 to start, and the second lifting device 61 drives the layer-full pressing device 6 to the height of the first webbing layer. The control device controls the electric push rod 625 to start and push out to press the pressing mechanism 62 to the outermost circle of the first webbing layer. Since the pressing mechanism 62, i.e., the layer-full pressing device 6, is integrally arranged on the outer edge 205 of the step of the rotating platform 20, it will rotate with the rotating platform 20. Therefore, when the pressing mechanism 62 is pressed on a point on the outermost circle of the first webbing layer, it can remain relatively fixed with the position of the first webbing layer, thereby fixing the outermost webbing of the first webbing layer. After the webbing guide mechanism 31 rises, the reel 204 continues to rotate and the webbing can be wound to form the second webbing layer. When the full layer detection device 4 detects that the layer thickness has reached the second set value, that is, after a certain number of turns of ribbon have been wound on the second ribbon layer, the control device controls the tape pressing mechanism 62 to release the fixation of the outermost ribbon of the first ribbon layer. At this time, the winding of the second ribbon layer will no longer cause the outermost ribbon of the first ribbon layer to detach. Specifically, the reel 204 continues to rotate to rewind the second ribbon layer. When the second ribbon layer is full, the control device repeats the above control operation to form a rewinding structure with a number of n layers of ribbon layers. When unwinding, the ribbon only needs to be continuously pulled upward, and the ribbon will be detached layer by layer in an orderly manner. There is no need to rotate the reel 204, which avoids the stress deformation that may occur in the ribbon during unwinding, further ensuring product quality.
