Description

Technical Field

[0001] This invention relates to the field of roll material winding equipment, and particularly to an intelligent winding equipment for waterproof roll materials. Background Technology

[0002] The waterproof membrane winding equipment is located at the end of the waterproof membrane production line. It is used to receive long strips of waterproof membrane and wind up the rated length of the membrane onto a roll. During the winding process, when the length of the waterproof membrane on a roll reaches the rated length, the waterproof membrane needs to be cut. Then, the wound waterproof membrane and the roll are packaged, and a new roll is placed to start the winding operation again.

[0003] During the cutting and roll replacement of the waterproof membrane, the winding equipment was stopped and no winding operation was performed. However, the production equipment of the waterproof membrane did not stop working simultaneously. The waterproof membrane continued to move towards the winding equipment through the conveyor equipment, causing the long strip of waterproof membrane to bulge in the middle, affecting the quality of the finished waterproof membrane. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an intelligent waterproof membrane winding device that can continuously wind up waterproof membranes without stopping the machine and switching between rolls, thereby improving the quality of the finished waterproof membrane.

[0005] According to an embodiment of the present invention, a smart rewinding device for waterproof membrane includes: a rewinding device for clamping a roll, and the rewinding device is capable of driving the roll to rotate circumferentially along the roll to wind and store the waterproof membrane in the roll. A circulating conveying device is provided with multiple winding devices. The circulating conveying device has at least a pre-winding position, a transition position, a winding position, and a packing position. The circulating conveying device can drive each winding device to pass through the pre-winding position, the transition position, the winding position, and the packing position in sequence. The winding device can stop at the pre-winding position, the winding position, and the packing position respectively. The movement path of the winding device from the pre-winding position and the transition position to the winding position is arc-shaped. A cutting device is disposed between the transition position and the winding position, and the cutting device is used to cut the waterproof roll material; When the winding device is located at the pre-winding position, the roll does not contact the waterproof membrane. When the winding device moves from the pre-winding position toward the transition position and continues to move to the winding position, the roll contacts and is fixed to the waterproof membrane. When the winding device is located at the winding position, the winding device can drive the roll to rotate and wind up the waterproof membrane.

[0006] The intelligent winding device for waterproof membrane according to embodiments of the present invention has at least the following beneficial effects: the winding device in the pre-winding position will move to the winding position after passing through the transition position; the winding device in the winding position will move to the packaging position; and the winding device in the packaging position will move back to the pre-winding position. Therefore, even if the winding device in the winding position stops winding, the waterproof membrane will still be pulled along when the winding device moves from the winding position to the packaging position. It is only necessary to adjust the moving speed of the winding device to be basically consistent with the feeding speed of the waterproof membrane to avoid the waterproof membrane from piling up and bulging. During the process of the winding device in the pre-winding position moving to the winding position, the drum on the winding device can contact the waterproof membrane. After reaching the winding position, the winding device can directly drive the drum to rotate to start a new winding operation.

[0007] According to some embodiments of the present invention, a guiding device is further included, which is disposed between the pre-winding position and the transition position. The guiding device has a guiding surface that extends from the pre-winding position toward the transition position. When the winding device moves from the pre-winding position to the transition position, the waterproof membrane can be pressed against the surface of the roll by the guiding surface.

[0008] According to some embodiments of the present invention, the guiding device includes a plurality of guide rollers, which are equidistant from the moving path of the winding device. The guide rollers are rotatable, and the rotation axis of the guide rollers is parallel to the axial direction of the drum. The side surface of the plurality of guide rollers facing the moving path of the winding device constitutes the guiding surface.

[0009] According to some embodiments of the present invention, a guide rail is further included, which is disposed between the transition position and the winding position. The cutting device is slidably connected to the guide rail. When the cutting device cuts the waterproof membrane, the cutting device can move along the guide rail so that the cutting device moves synchronously with the winding device.

[0010] According to some embodiments of the present invention, the guide rail includes a connected synchronization section and a release section. The synchronization section has an arc-shaped guide path, and the guide path of the synchronization section is coaxially arranged with the moving path of the winding device. The cutting device moves along the synchronization section and the release section. In the synchronization section, the cutting device moves synchronously with the winding device. In the release section, the cutting device disengages from the winding device and retracts to the synchronization section.

[0011] According to some embodiments of the present invention, the cutting device is provided with a first contact member, the winding device is provided with a second contact member, and the distance between the guide path of the release section and the moving path of the winding device gradually increases in the guide rail along the direction away from the synchronization section. When the winding device moves from the transition position to the winding position, the second contact member can contact the first contact member and drive the first contact member to move. When the cutting device moves to the release section, the second contact member separates from the first contact member, so that the cutting device can retract to the synchronization section.

[0012] According to some embodiments of the present invention, the guide rail is provided with an elastic element connected to the cutting device. The elastic element is configured to deform to store energy when the cutting device moves from the synchronization section toward the release section, and has a tendency to push the cutting device back to the synchronization section.

[0013] According to some embodiments of the present invention, the circulating conveying device includes an annular circulating track and a drive assembly, wherein a plurality of the winding devices are slidably connected to the circulating track, and the drive assembly is drively connected to the winding devices to drive the winding devices to move along the circulating track.

[0014] According to some embodiments of the present invention, a conveying device is also included, which is disposed at the packing position, such that when the winding device moves to the packing position, the wound waterproof membrane and the roll can be conveyed away from the winding device by the conveying device.

[0015] According to some embodiments of the present invention, the conveying device includes a plurality of conveying rollers, the arrangement direction of which is perpendicular to the movement path of the winding device.

[0016] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0023] Reference Figure 1 and Figure 2 As shown, an embodiment of the intelligent waterproof membrane winding device of the present invention includes a winding device 100, a circulating conveying device 200, and a cutting device 300.

[0024] The winding device 100 is used to clamp the roll 001, and the winding device 100 can drive the roll 001 to rotate circumferentially to wind and store the waterproof membrane in the roll 001; the circulating conveyor 200 is provided with multiple winding devices 100, and the circulating conveyor 200 has at least a pre-winding position 210, a transition position 220, a winding position 230 and a packing position 240, and the circulating conveyor 200 can drive each winding device 100. The winding device 100 sequentially passes through the pre-winding position 210, the transition position 220, the winding position 230, and the packing position 240, and can stop at the pre-winding position 210, the winding position 230, and the packing position 240 respectively. The movement path of the winding device 100 from the pre-winding position 210 and the transition position 220 to the winding position 230 is arc-shaped. The cutting device 300 is disposed between the transition position 220 and the winding position 230, and the cutting device 300 is used to cut the waterproof membrane. When the winding device 100 is in the pre-winding position 210, the drum 001 does not contact the waterproof membrane. When the winding device 100 moves from the pre-winding position 210 to the transition position 220 and continues to move to the winding position 230, the drum 001 contacts and is fixed to the waterproof membrane. When the winding device 100 is in the winding position 230, the winding device 100 can drive the drum 001 to rotate and wind up the waterproof membrane.

[0025] After the winding device 100 clamps the roll 001, it can drive the roll 001 to rotate around an axis, which is the central axis of the roll 001. One end of the waterproof membrane is connected to the roll 001, so when the roll 001 is driven to rotate, the waterproof membrane can be wound onto the roll 001. It should be understood that the winding device 100 can be equipped with a drive motor and a clamping assembly. The clamping assembly is used to clamp the roll 001, and the drive motor is used to drive the clamping assembly and the roll 001 to rotate together. Of course, the winding device 100 can also adopt other structures to achieve the aforementioned functions. The winding device 100 is a relatively mature technology, and its specific structure will not be described in detail in this application.

[0026] The circulating conveyor 200 has at least a pre-winding position 210, a transition position 220, a winding position 230, and a packing position 240. A winding device 100 can stop at each of these positions. The circulating conveyor 200 has multiple winding devices 100. Therefore, during the winding operation, the winding device 100 at the winding position 230 drives the roll 001 to rotate to wind up the waterproof membrane. The winding device 100 at the packing position 240 has the wound waterproof membrane on it. The packing equipment can pack the waterproof membrane at the packing position 240 and then unload it. It should be understood that the packing equipment is also mature prior art, and its specific structure will not be described in detail here. A new roll 001 is installed on the winding device 100 at the pre-winding position 210, but at this time the roll 001 is not in contact with the waterproof membrane.

[0027] When the roll 001 of the winding device 100 at the winding position 230 has wound up the rated length of waterproof membrane, the winding device 100 will stop driving the roll 001 to rotate. At the same time, the circulating conveyor 200 will start, driving each winding device 100 to move. For example, the winding device 100 at the pre-winding position 210 will move to the winding position 230 after passing through the transition position 220, the winding device 100 at the winding position 230 will move to the packing position 240, and the winding device 100 at the packing position 240 will move back to the pre-winding position 210. Therefore, even if the winding device 100 at the winding position 230 stops winding, when the winding device 100 moves from the winding position 230 to the packing position 240, it will still pull the waterproof membrane to move. It is only necessary to adjust the moving speed of the winding device 100 to be basically consistent with the feeding speed of the waterproof membrane to avoid the waterproof membrane from piling up and bulging. It is important to understand that when the winding device 100 at the pre-winding position 210 moves towards the transition position 220, it will come into contact with the waterproof membrane, and the winding device 100 will also move synchronously with the waterproof membrane. After the winding device 100 passes the transition position 220, the cutting device 300 will activate to cut the waterproof membrane between the winding device 100 and the previous winding device 100 (i.e., the winding device 100 that moved from the winding position 230 to the packing position 240). After the winding device 100 moves to the winding position 230, the winding device 100 will start driving the drum 001 to rotate for a new winding operation, and the circulating conveyor 200 will simultaneously stop driving the winding device 100 to move. During the aforementioned process, the waterproof membrane is always in motion, that is, the waterproof membrane moves with the winding device 100, and then moves as the drum 001 rotates to start winding. The waterproof membrane will not accumulate and bulge due to the cessation of movement.

[0028] When the circulating conveyor 200 drives each winding device 100 to move, the empty roll 001 moves from the pre-winding position 210 toward the winding position 230 and contacts the waterproof membrane, and performs winding operations at the winding position 230. Therefore, the waterproof membrane will also roughly pass through the pre-winding position 210, the transition position 220 and the winding position 230.

[0029] Reference Figure 1 and Figure 3 As shown, it can be understood that a guide device 400 is also included. The guide device 400 is disposed between the pre-winding position 210 and the transition position 220. The guide device 400 has a guide surface 401 that extends from the pre-winding position 210 toward the transition position 220. When the winding device 100 moves from the pre-winding position 210 to the transition position 220, the waterproof membrane can be pressed against the surface of the roll 001 by the guide surface 401.

[0030] When the circulating conveyor 200 drives each winding device 100 to move, the winding device 100 located at the pre-winding position 210 will move through the transition position 220 and then reach the winding position 230. Simultaneously, the roll 001 of this winding device 100 will contact the waterproof membrane during its movement and then enter the area of ​​the guide device 400. At this time, the waterproof membrane is located between the guide surface 401 and the roll 001, and under the action of the guide surface 401, the waterproof membrane is pressed against the surface of the roll 001. Preferably, the surface of the roll 001 is provided with an adhesive layer, so the waterproof membrane can be fixed to the roll 001. The guide device 400 plays a role in improving the fixing effect, driving the waterproof membrane to contact the surface of the roll 001 through the guide surface 401.

[0031] As the winding device 100 continues to be driven to move by the circulating conveyor 200, the drum 001 and the waterproof membrane remain relatively stationary, and the waterproof membrane will not detach from the drum 001. Furthermore, after the drum 001 passes the transition position 220, the cutting device 300 cuts the waterproof membrane. At this time, the waterproof membrane between the drum 001 and the previous drum 001 is cut off. When the drum 001 moves to the winding position 230, the drum 001 can rotate to perform the winding operation.

[0032] It is understood that the guiding device 400 includes a plurality of guide rollers 410, which are equidistant from the moving path of the winding device 100. The guide rollers 410 are rotatable, and the rotation axis of the guide rollers 410 is parallel to the axial direction of the drum 001. The surface of the plurality of guide rollers 410 facing the moving path of the winding device 100 forms a guide surface 401.

[0033] As the roll 001 moves from the pre-winding position 210 to the transition position 220, the waterproof membrane moves between the roll 001 and the guide roller 410. At this time, the guide roller 410 can rotate, and the friction between the guide roller 410 and the waterproof membrane is lower. While pressing the waterproof membrane onto the roll 001, it can also reduce the risk of the waterproof membrane being peeled off the roll 001 due to high friction.

[0034] Reference Figure 3 and Figure 4 As shown, it can be understood that a guide rail 500 is also included. The guide rail 500 is disposed between the transition position 220 and the winding position 230. The cutting device 300 is slidably connected to the guide rail 500. When the cutting device 300 cuts the waterproof membrane, the cutting device 300 can move along the guide rail 500 so that the cutting device 300 moves synchronously with the winding device 100.

[0035] When the cutting device 300 cuts the waterproof membrane, the membrane is still in motion. If the cutting device 300 were stationary, a slanted cut would be left on the membrane. Therefore, a guide rail 500 is provided. After the winding device 100 carrying the roll 001 passes the transition position 220, the cutting device 300 moves along the guide rail 500. The cutting device 300 moves synchronously with the winding device 100 to keep the cutting device 300 and the waterproof membrane relatively stationary. When the waterproof membrane is cut at this time, the cut will be perpendicular to the length of the membrane.

[0036] It is important to understand that the cutting device 300 specifically includes a guide rod and a cutting wheel mounted on the guide rod. The guide rod is perpendicular to the length direction of the waterproof membrane. When the cutting wheel moves along the guide rod, it can cut the waterproof membrane along a direction perpendicular to its length. It is also important to understand that the cutting device 300 being relatively stationary relative to the waterproof membrane means that both the guide rod and the cutting wheel are stationary relative to the waterproof membrane along its winding / movement path. However, during the cutting process, the cutting wheel still needs to move along a direction perpendicular to the length of the waterproof membrane to achieve the cutting effect.

[0037] It is understood that the guide rail 500 includes a connected synchronous section 510 and a release section 520. The synchronous section 510 has an arc-shaped guide path. The guide path of the synchronous section 510 is coaxially arranged with the moving path of the winding device 100. The cutting device 300 moves along the synchronous section 510 and the release section 520. In the synchronous section 510, the cutting device 300 moves synchronously with the winding device 100. In the release section 520, the cutting device 300 disengages from the winding device 100 and retracts to the synchronous section 510.

[0038] Specifically, after the winding device 100 carrying the roll 001 passes through the transition position 220, the cutting device 300 begins to move synchronously. During its movement along the synchronization section 510, the cutting device 300 and the waterproof membrane remain relatively stationary along the membrane's movement path. The cutting wheel on the cutting device 300 actuates, cutting the waterproof membrane. It is important to understand that the cutting wheel must complete the cutting operation on the waterproof membrane before the cutting device 300 enters the release section 520.

[0039] After the waterproof membrane is cut, the cutting device 300 continues to move with the winding device 100 into the release section 520. Upon entering the release section 520, the cutting device 300 is disconnected from the synchronous movement of the winding device 100, and the cutting device 300 can detach from the winding device 100 and retract to the synchronization section 510, awaiting the next cutting operation. It is important to understand that the cutting operation is performed after the waterproof membrane on one roll 001 has been wound up, during the process of switching rolls 001.

[0040] Reference Figure 5 As shown, it can be further understood that the cutting device 300 is provided with a first contact member 610, the winding device 100 is provided with a second contact member 620, and in the guide rail 500, along the direction away from the synchronization section 510, the distance between the guide path of the release section 520 and the moving path of the winding device 100 gradually increases. When the winding device 100 moves from the transition position 220 to the winding position 230, the second contact member 620 can contact the first contact member 610 and drive the first contact member 610 to move. When the cutting device 300 moves to the release section 520, the second contact member 620 separates from the first contact member 610, so that the cutting device 300 can retract to the synchronization section 510.

[0041] The winding device 100 will only move to switch positions after completing the winding operation on a roll 001. At this time, the winding device 100, having passed through the transition position 220, approaches the cutting device 300 until the second contact member 620 contacts the first contact member 610, causing the first contact member 610 to move. That is, the cutting device 300 moves synchronously with the winding device 100, and the cutting wheel on the cutting device 300 actuates, cutting the waterproof membrane. The second contact member 620 continues to push the first contact member 610 to move, and the cutting device 300 will move from the synchronization section 510 into the release section 520. As the distance between the guide path of the release section 520 and the moving path of the winding device 100 gradually increases along the direction away from the synchronization section 510, the first contact member 610 and the second contact member 620 gradually move away from each other. The second contact member 620 breaks contact with the first contact member 610, and the second contact member 620 can no longer apply external force to drive the first contact member 610 to move. Therefore, the cutting device 300 can retract to the synchronization section 510. It should be understood that in some embodiments, the second contact 620 will only contact the first contact 610 when the winding device 100 approaches the cutting device 300. That is, when the cutting device 300 cuts the waterproof membrane, the cut surface is closer to the roll 001 on the winding device 100. Therefore, during winding, there will be no long suspended waterproof membrane on the roll 001, and the waterproof membrane will not bulge after winding.

[0042] Understandably, the guide rail 500 is provided with an elastic element 630, which is connected to the cutting device 300. The elastic element 630 is configured to deform to store energy when the cutting device 300 moves from the synchronization section 510 toward the release section 520, and has a tendency to push the cutting device 300 back to the synchronization section 510.

[0043] In some embodiments, the elastic member 630 is configured to be compressible and store energy when the cutting device 300 moves from the synchronization section 510 toward the release section 520. When the cutting device 300 moves to the release section 520, the second contact member 620 disconnects from the first contact member 610, and the elastic member 630 resets to drive the cutting device 300 back to the synchronization section 510.

[0044] In other embodiments, the elastic element 630 is configured to be stretched and store energy as the cutting device 300 moves from the synchronization section 510 toward the release section 520. When the cutting device 300 moves to the release section 520, the second contact element 620 disengages from the first contact element 610, and the elastic element 630 resets to drive the cutting device 300 back to the synchronization section 510. Preferably, the elastic element 630 is a spring.

[0045] It is understood that the circulating conveying device 200 includes an annular circulating track 201 and a drive assembly. Multiple winding devices 100 are slidably connected to the circulating track 201, and the drive assembly is drively connected to the winding devices 100 to drive the winding devices 100 to move along the circulating track 201.

[0046] The drive assembly preferably includes a chain disposed on a circulation track 201, in which adjacent winding devices 100 are connected by the chain. When the transmission mechanism drives the chain to move, each winding device 100 will be driven by the chain to move synchronously.

[0047] It is understandable that it also includes a conveying device 700, which is set at the packing position 240. When the winding device 100 moves to the packing position 240, the wound waterproof membrane and the roll 001 can be conveyed by the conveying device 700 and detached from the winding device 100.

[0048] When the winding device 100 at the winding position 230 drives the drum 001 to complete the winding of the waterproof membrane, the winding device 100 will move to the packing position 240. At this time, the wound waterproof membrane will be located in the conveying device 700. After the packing operation is completed, the winding device 100 will release the drum 001, and the waterproof membrane can be transferred by the conveying device 700 to get off the winding device 100, thus completing the unloading of the finished waterproof membrane.

[0049] It is understood that the conveying device 700 includes a plurality of conveying rollers 710, and the arrangement direction of the plurality of conveying rollers 710 is perpendicular to the movement path of the winding device 100.

[0050] The conveyor roller 710 can contact the outer surface of the finished waterproof membrane. When the conveyor roller 710 is driven to roll, it can move the waterproof membrane. As long as the winding device 100 releases its grip on the roll 001, the waterproof membrane and the roll 001 can be transferred away from the winding device 100 by the conveying device 700.

[0051] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
