Description

Technical Field

[0001] The present invention belongs to the technical field of the production of waterproof coiled materials, and particularly relates to an automatic winding device and method for waterproof coiled materials. Background Art

[0002] High molecular waterproof coiled materials are mainly used in building walls, roofs, tunnels, highways, landfills, etc., and are flexible building materials in a rollable shape that can resist the leakage of external rainwater and groundwater. They are a basic infrastructure material. After the production and processing of high molecular waterproof coiled materials, a winding mechanism is used to store and organize the waterproof coiled materials, so as to facilitate the storage, transportation and sales of high molecular waterproof coiled materials.

[0003] In the prior art, the commonly used winding devices for high molecular waterproof coiled materials are to manually put a paper tube on an air shaft, then manually turn it over and start the head to make the high molecular waterproof coiled material wind around the paper tube for half a circle, and then use the method of manually applying tape to bond the end of the incoming high molecular waterproof coiled material to the paper tube. Then start the machine to make the air shaft rotate, and the air shaft of the equipment rotates continuously to achieve winding. After winding a certain number of turns, the operation is carried out to cut the roll and fix and package it, completing a cycle.

[0004] In the prior art, a lot of manual participation is required, especially the bonding of high molecular waterproof coiled materials and paper tubes, which is time-consuming and laborious. The overall automation and intelligence level is not high. It is urgent to adopt an intelligent solution for transformation to cancel manual operation, improve the intelligence level and production efficiency.

[0005] For products such as non-woven fabrics, there are fully automatic winding mechanisms, but the characteristics of high molecular waterproof coiled materials are very different from those of products such as non-woven fabrics. The technologies and devices of the automatic winding mechanism for non-woven fabrics cannot be applied to the automatic winding of high molecular waterproof coiled materials, and new technologies and devices must be developed.

[0006] In summary, there is an urgent need to provide a device and method for automatic winding that can improve production efficiency and realize continuous winding of waterproof coiled materials. Summary of the Invention

[0007] The purpose of the present invention is to provide a device and method for automatic winding that can improve production efficiency and realize continuous winding of waterproof coiled materials.

[0008] The above object is achieved through the following technical scheme: an automatic winding device for waterproof coiled material, comprising a frame, a driving mechanism, a lifting mechanism, a pressing mechanism and a profiling guide mechanism, wherein the driving mechanism is used to drive the winding shaft to rotate to wind the waterproof coiled material, the lifting mechanism is arranged on the frame, the lifting mechanism comprises a lifting platform, the pressing mechanism and the profiling guide mechanism are arranged on the lifting platform, the pressing mechanism comprises a pressing roller and a roller pressing member, the pressing roller is fixedly arranged in the middle of the lifting platform, the profiling guide mechanism comprises a profiling component and a driving component, the driving component comprises a first driving member and a second driving member, the profiling component comprises a first profiling plate and a second profiling plate, the first profiling plate and the second The profiling plate can form a profiling circle, which is located above the pressing roller. The first driving member and the second driving member are respectively connected to the first profiling plate and the second profiling plate in a transmission manner, and are used to drive the first profiling plate and the second profiling plate to rotate along different rotating shafts respectively. The roller pressing component includes a supporting base and a rotating shaft and a third driving member arranged on the supporting base. The rotating shaft is connected to a pressing roller through a rotating arm. The supporting base is arranged on one side of the lifting platform. The third driving member is connected to the rotating shaft in a transmission manner and can drive the pressing roller to rotate along the rotating shaft. A spacing is reserved between the lower side of the second profiling plate and the pressing roller, and the pressing roller can rotate to the spacing and press the winding shaft.

[0009] The present invention is used for the automatic winding of waterproof coiled materials. The waterproof coiled materials are continuously conveyed to a predetermined position through previous processes. The lifting mechanism operates to lift the pressing roller, and the pressing roller presses against the winding shaft. The waterproof coiled materials are clamped between the pressing roller and the winding shaft. The profiling plate assembly encloses the winding shaft within a profiling circle, and a gap with a predetermined distance is reserved between the first profiling plate and the second profiling plate and the winding shaft. The driving mechanism drives the winding shaft to rotate to start winding the waterproof coiled materials. At the same time, the conveying device operates to continuously convey the waterproof coiled materials. The end of the waterproof coiled materials enters the gap between the first profiling plate, the second profiling plate, and the winding shaft. Under the guiding action of the first profiling plate and the second profiling plate, the end of the waterproof coiled materials winds around the winding shaft. When the end of the waterproof coiled materials runs below the second profiling plate, the third driving member drives the pressing roller to move to the position at a distance from the pressing roller below the second profiling plate. The pressing roller presses the end of the waterproof coiled materials and the second layer of waterproof coiled materials tightly against the winding shaft together. The driving mechanism continues to drive the winding shaft to rotate for winding. When the waterproof coiled materials are wound to the second circle, the first driving member drives the first profiling plate to rotate to a predetermined angle to slightly increase the diameter of the profiling circle. When winding more than three circles, the first driving member and the second driving member respectively drive the first profiling plate and the second profiling plate to fully open to complete the introduction and winding actions of the waterproof coiled materials. The lifting mechanism drives the pressing mechanism and the profiling guiding mechanism, and the overall winding mechanism returns downward. At this time, due to the pressing action of the front pressing roller and the toughness and strength characteristics of the waterproof coiled materials, the pre-tension force during the winding process of the waterproof coiled materials will continue to be retained. The driving mechanism continues to drive the winding shaft to rotate for winding until the waterproof coiled materials on the paper tube are wound to a predetermined size.

[0010] The present invention makes full use of the material characteristics of the waterproof coiled materials. The waterproof coiled materials have certain flexibility, extensibility, and mechanical strength. The profiling assembly and the pressing roller are designed so that the second layer presses on the first layer to establish a pre-tension force in the first circle of the waterproof coiled materials. Only by relying on the pre-tension force to generate friction can the rotational torque be transmitted from the winding shaft to the waterproof coiled materials to achieve rotational winding. The key to establishing the pre-tension force is that when the waterproof coiled materials are in a taut state, the waterproof coiled materials must be wound more than one circle, that is, the second circle presses on the first circle to release the constraint.

[0011] A further technical solution is that the profiling guiding mechanism includes a mounting base, on which a central rotating shaft and a fixing member are provided. A transmission rod is provided on the central rotating shaft, and the first profiling plate is fixed to the transmission rod. The first driving member is in transmission connection with the central rotating shaft and can drive the first profiling plate to rotate along the central rotating shaft. The fixing member is provided with a lateral rotating shaft, on which a connecting plate is provided. The second profiling plate is connected to the connecting plate. The second driving member is in transmission connection with the lateral rotating shaft and can drive the second profiling plate to rotate along the lateral rotating shaft. The lateral rotating shaft is located above the central rotating shaft. With such a setting, when the waterproof coiled material is wound to the second circle, the first driving member drives the first profiling plate to rotate to a predetermined angle, so that the diameter of the profiling circle is slightly enlarged. When it is wound to more than the third circle, the first driving member and the second driving member respectively drive the first profiling plate and the second profiling plate to fully open, completing the introduction and winding actions of the waterproof coiled material.

[0012] A further technical solution is that the lifting mechanism further includes a fixed bottom plate, a lifting assembly and a linear bearing assembly. The fixed bottom plate is connected to the frame. The fixed end of the lifting assembly is fixed on the fixed bottom plate, and the movable end is connected to the lifting platform. The lifting platform is connected to the fixed bottom plate through the linear bearing assembly.

[0013] A further technical solution is that the lifting assembly includes a cylinder. A floating joint is provided at the movable end of the air rod of the cylinder, and the floating joint is connected to the bottom of the lifting platform. With such a setting, the automatic lifting assembly has an up-and-down floating function. As the number of winding circles of the waterproof coiled material increases, the floating function can cause the lifting device to descend slightly, ensuring that the waterproof coiled material will not be overly tightened.

[0014] A further technical solution is that a reel fixing plate for fixedly supporting the winding shaft is provided on the frame.

[0015] A further technical solution is that the driving mechanism includes a gear reduction box and a driving motor. The output shaft of the driving motor is connected to the input shaft of the gear reduction box, and the output shaft of the gear reduction box is used for transmission connection with the winding shaft. The gear reduction box is conducive to realizing the function of speed reduction and torque increase, aiming to wind the waterproof film tightly.

[0016] To achieve the above object, the present invention also provides a method for automatically winding a waterproof coiled material, which is characterized in that it is carried out by any one of the above-mentioned waterproof coiled material automatic winding devices, and the specific steps include:

[0017] (1) Using a conveying device to convey the waterproof coiled material to a predetermined position;

[0018] (2) The lifting mechanism operates to lift the pressing roller. The pressing roller presses against the winding shaft, and the waterproof coiled material is clamped between the pressing roller and the winding shaft. The profiling plate assembly encloses the winding shaft within a profiling circle, and there is a gap with a predetermined distance reserved between the first profiling plate and the second profiling plate and the winding shaft.

[0019] (3) The driving mechanism drives the winding shaft to rotate, and starts to wind the waterproof coiled material. At the same time, the conveying device operates to continuously convey the waterproof coiled material. The end of the waterproof coiled material enters the gap between the first profiling plate, the second profiling plate and the winding shaft, and under the guiding action of the first profiling plate and the second profiling plate, the end of the waterproof coiled material winds around the winding shaft.

[0020] (4) When the end of the waterproof coiled material runs to below the second profiling plate, the third driving member drives the pressing roller to move to the position at a distance from the pressing roller below the second profiling plate. The pressing roller presses the end of the waterproof coiled material and the second layer of waterproof coiled material tightly against the winding shaft together, and the driving mechanism continues to drive the winding shaft to rotate for winding.

[0021] (5) When the waterproof coiled material is wound to the second circle, the first driving member drives the first profiling plate to rotate to a predetermined angle, so that the diameter of the profiling circle is slightly enlarged. When it is wound to more than the third circle, the first driving member and the second driving member respectively drive the first profiling plate and the second profiling plate to fully open, completing the introduction and winding actions of the waterproof coiled material.

[0022] (6) The lifting mechanism drives the pressing mechanism and the profiling guiding mechanism and the overall winding mechanism to return downward. At this time, due to the pressing action of the pressing roller in steps (2) to (5), and at the same time the toughness and strength characteristics of the waterproof coiled material, the pre-tension force during the winding process of the waterproof coiled material will continue to be retained.

[0023] (7) The driving mechanism continues to drive the winding shaft to rotate for winding until the waterproof coiled material on the paper tube is wound to a predetermined size.

[0024] A further technical solution is that the automatic winding device for the waterproof coiled material is provided with a sensor for detecting the tension of the waterproof coiled material. In step (4), through the synchronous transmission of the transmission mechanism and by turning on the tension control of the automatic winding device for the waterproof coiled material, the tension of the waterproof coiled material is controlled at a predetermined value.

[0025] Compared with the prior art, the present invention realizes the full-automatic winding of the waterproof coiled material. During the winding process, no manual participation is required, the equipment has a high level of intelligence and high labor productivity; at the same time, there is no need for the bonding of the waterproof coiled material and the paper tube. The method of automatic head generation, guiding and tightening of the waterproof coiled material makes the waterproof coiled material closely adhere to the paper tube, and the rotational torque is transmitted to the paper tube through the air-expansion shaft and then to the waterproof coiled material, enabling the continuous rotation of the waterproof coiled material roll and realizing continuous winding.

[0048] The present invention is used for automatic winding of waterproof coiled material 7, such as Figure 1 and Figures 5 to 8, the waterproof coiled material 7 is continuously conveyed to a predetermined position through the previous process. The lifting mechanism 4 operates to lift the pressing roller 8, and the pressing roller 8 presses against the winding shaft 9. The waterproof coiled material 7 is clamped between the pressing roller 8 and the winding shaft 9. The profiling plate assembly encloses the winding shaft 9 within a profiling circle, and there is a gap with a predetermined distance between the first profiling plate 61 and the second profiling plate 62 and the winding shaft 9; the driving mechanism 3 drives the winding shaft 9 to rotate, and starts to wind the waterproof coiled material 7. At the same time, the conveying device operates to continuously convey the waterproof coiled material 7. The end of the waterproof coiled material 7 enters the gap between the first profiling plate 61, the second profiling plate 62 and the winding shaft 9, and under the guiding action of the first profiling plate 61 and the second profiling plate 62, the end of the waterproof coiled material 7 winds around the winding shaft 9; when the end of the waterproof coiled material 7 runs below the second profiling plate 62, the third driving member 54 drives the pressing roller 51 to move to a position at a distance from the pressing roller 8 below the second profiling plate 62, and the pressing roller 51 presses the end of the waterproof coiled material 7 and the second layer of the waterproof coiled material 7 tightly against the winding shaft 9 together. The driving mechanism 3 continues to drive the winding shaft 9 to rotate for winding; when the waterproof coiled material 7 is wound to the second circle, the first driving member 63 drives the first profiling plate 61 to rotate to a predetermined angle, so that the diameter of the profiling circle is slightly enlarged.

[0049] The present invention makes full use of the material characteristics of the waterproof coiled material 7. The waterproof coiled material 7 has certain flexibility, extensibility and mechanical strength. The profiling assembly and the pressing roller 51 are designed to make the second layer press on the first layer, and a pre-tension force is established in the first circle of the waterproof coiled material 7. Only by relying on the pre-tension force to generate friction can the rotation torque be transmitted from the reel to the waterproof coiled material 7 to achieve rotary winding. The key to establishing the pre-tension force is that when the waterproof coiled material 7 is in a taut state, the waterproof coiled material 7 must be wound more than one circle, that is, the second circle presses on the first circle to release the constraint.

[0050] On the basis of the above embodiments, in another embodiment of the present invention, as Figure 2, the profiling guiding mechanism 6 includes a mounting base 65, on which a central rotating shaft 66 and a fixing member 67 are provided. A transmission rod 70 is provided on the central rotating shaft 66, and the first profiling plate 61 is fixed on the transmission rod 70. The first driving member 63 is in transmission connection with the central rotating shaft 66 and can drive the first profiling plate 61 to rotate along the central rotating shaft 66.

With such a setting, as Figure 8 , when the waterproof coiled material 7 is wound to the second circle, the first driving member 63 drives the first profiling plate 61 to rotate to a predetermined angle, so that the diameter of the profiling circle is slightly enlarged. When it is wound to more than the third circle, the first driving member 63 and the second driving member 64 respectively drive the first profiling plate 61 and the second profiling plate 62 to fully open, completing the introduction and winding actions of the waterproof coiled material 7.

A floating joint is provided at the movable end of the air rod of the cylinder 44, and the floating joint is connected to the bottom of the lifting platform 41. With such a setting, the automatic lifting assembly has an up and down floating function. As the number of winding circles of the waterproof coiled material 7 increases, the floating function can cause the lifting device to descend slightly, ensuring that the waterproof coiled material 7 will not be overly tightened.

[0053] On the basis of the above embodiment, in another embodiment of the present invention, as Figure 1 , a reel fixing plate 2 for fixedly supporting the winding shaft 9 is provided on the frame 1.

The gear reduction box 31 is conducive to realizing the function of speed reduction and torque increase, aiming to make the waterproof film tightly wound.

[0055] The present invention also provides an automatic winding method for the waterproof coiled material 7, and the embodiments are as follows. Figures 5 to 8 , which is carried out by the automatic winding device for the waterproof coiled material 7 described in any one of the above, and the specific steps include:

[0056] (1) Use the conveying device to convey the waterproof coiled material 7 to a predetermined position;

[0057] (2) As Figure 5 and Figure 6 , the lifting mechanism 4 acts to lift the pressing roller 8, the pressing roller 8 presses against the winding shaft 9, the waterproof coiled material 7 is clamped between the pressing roller 8 and the winding shaft 9, the profiling plate assembly encloses the winding shaft 9 within the profiling circle, and a gap with a predetermined distance is reserved between the first profiling plate 61 and the second profiling plate 62 and the winding shaft 9;

[0058] (3) As Figure 6 , the driving mechanism 3 drives the winding shaft 9 to rotate, starts to wind the waterproof coiled material 7, and at the same time the conveying device works to continuously convey the waterproof coiled material 7.

[0059] (4) As Figure 7 , when the end of the waterproof coiled material 7 runs to the lower part of the second profiling plate 62, the third driving member 54 drives the pressing roller 51 to move to the position at the spacing between the lower part of the second profiling plate 62 and the pressing roller 8, and the pressing roller 51 presses the end of the waterproof coiled material 7 and the second layer of the waterproof coiled material 7 against the winding shaft 9 together, and the driving mechanism 3 continues to drive the winding shaft 9 to rotate for winding;

[0060] (5) When the waterproof coiled material 7 is wound to the second circle, the first driving member 63 drives the first profiling plate 61 to rotate to a predetermined angle, so that the diameter of the profiling circle is slightly enlarged. As Figure 8 , when it is wound to more than the third circle, the first driving member 63 and the second driving member 64 respectively drive the first profiling plate 61 and the second profiling plate 62 to be fully opened, and the introduction and winding actions of the waterproof coiled material 7 are completed;

[0061] (6) The lifting mechanism 4 drives the pressing mechanism, the profiling guiding mechanism and the integral winding mechanism of the waterproof coiled material 7 to return downward. At this time, due to the pressing action of the pressing roller 8 in steps (2) to (5), and the toughness and strength characteristics of the waterproof coiled material 7, the pre-tension force during the winding process of the waterproof coiled material 7 will continue to be retained;

[0062] (7) The driving mechanism 3 continues to drive the winding shaft 9 to rotate for winding until the waterproof coiled material 7 on the paper tube is wound to a predetermined size.

[0063] Based on the above embodiments, in another embodiment of the present invention, the automatic winding device of the waterproof coiled material 7 is provided with a sensor for detecting the tension of the waterproof coiled material 7.

(5) When the waterproof coiled material is wound to the second circle, the first driving member drives the first profiling plate to rotate to a predetermined angle, so that the diameter of the profiling circle expands within a small range. When it is wound to more than the third circle, the first driving member and the second driving member respectively drive the first profiling plate and the second profiling plate to open completely, completing the introduction and winding actions of the waterproof coiled material. (6) The lifting mechanism drives the pressing mechanism and the profiling guiding mechanism as a whole to return downward. At this time, due to the pressing action of the pressing roller in steps (2) to (5), and at the same time, due to the toughness and strength characteristics of the waterproof coiled material, the pre-tension force during the winding process of the waterproof coiled material will continue to be retained. (7) The driving mechanism continues to drive the winding shaft to rotate for winding until the waterproof coiled material on the paper tube is wound to a predetermined size.

8. The automatic winding method for waterproof coiled materials according to claim 7, characterized in that, The automatic winding device for the waterproof coiled material is provided with a sensor for detecting the tension of the waterproof coiled material. In step (4), through the synchronous transmission of the transmission mechanism, the tension control of the automatic winding device for the waterproof coiled material is turned on, so that the tension of the waterproof coiled material is controlled at a predetermined value.
