[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0032] like Figures 1 to 8 As shown, the film material storage mechanism of the first aspect of this embodiment includes: a base 100, which has a first position; a lifting device 300 and a slider 330, which are arranged on the base 100, and the lifting device 300 is used to drive the slider 330 to rise and fall; a transport vehicle 200 and a winding roller 600, a positioning platform 210 is provided on the transport vehicle 200, and a placement portion for placing the winding roller 600 is provided on the top of the positioning platform 210, and the transport vehicle 200 can move to the first position so that the winding roller 600 moves at least partially to above the slider 330; a driving roller 410, which is rotatably arranged on the base 100, and the driving roller 410 is located above the slider 330, and the slider 330 can lift the winding roller 600 so that the slider 330 and the driving roller 410 clamp the end of the winding roller 600; a driving motor 420, which is arranged on the base 100, and the driving motor 420 is used to drive the driving roller 410 to rotate.

[0033] By applying the above-mentioned film material receiving mechanism, during use, the transport vehicle 200 can be controlled to move to the first position first, so that the end of the winding roller 600 placed on the placement portion moves to above the slider 330, and then the transport vehicle 200 can be controlled to move to the first position, so that the end of the winding roller 600 placed on the placement portion moves to above the slider 330, and then the film material to be received is fixed on the winding roller 600, and then the driving motor 420 is controlled to drive the driving roller 410 to rotate, so that the film material is wound on the winding roller 600; after the winding is completed, the film material is cut off, and the lifting device 300 is controlled to move to the first position. , driving the slider 330 to descend, so that the wound film roll falls onto the placement portion; finally, the transport vehicle 200 is controlled to transport the film roll on the placement portion; during the entire film storage process, the connection between the film roll and the rotating mechanism can be completed only by relying on the rise of the slider 330. Similarly, the film roll can be disassembled and transported to the placement portion only by relying on the lowering of the slider 330, and then transported away by the transport vehicle 200; the entire loading and unloading mechanism only needs to be raised and lowered to complete the loading and unloading of the winding roller 600, without the need for horizontal movement. Its structure is greatly simplified, and the assembly efficiency is also greatly improved compared to the traditional lifting mechanism.

[0034] The second aspect of this embodiment also provides a film material storage method, which uses the above-mentioned film material storage mechanism, and includes the following steps: S100, controlling the transport vehicle 200 to move to the first position, so that the end of the winding roller 600 placed on the placement portion moves to above the slider 330; S200, controlling the lifting device 300 to lift the slider 330, so that the slider 330 lifts the end of the winding roller 600 until the slider 330 and the driving roller 410 clamp the end of the winding roller 600 together; S300, fixing the film material to be stored on the winding roller 600, and then controlling the driving motor 420 to drive the driving roller 410 to rotate, so that the film material is wound on the winding roller 600; S400, after the winding is completed, cutting the film material, controlling the lifting device 300, driving the slider 330 to descend, so that the wound film material roll falls onto the placement portion; S500, controlling the transport vehicle 200 to transport the film material roll on the placement portion away.

[0035] In this embodiment, the base 100 generally refers to the basic structure of the entire film material storage mechanism, which is used to install and support other components, including Figure 1 The two vertical panels shown also include other brackets on the ground for installing and fixing the vertical panels and the lifting device 300.

[0036] like Figure 1As shown, the first position is located between the two vertical plates and is used for parking the transport vehicle 200. When the transport vehicle 200 is parked at the first position, the end of the winding roller 600 on the placement portion can move to the top of the slider 330, that is, the bottom of the driving roller 410. When the slider 330 rises, it can drive the winding roller 600 to rise together, so that the slider 330 and the driving roller 410 clamp the end of the winding roller 600. When the driving roller 410 rotates, the driving roller 410 drives the winding roller 600 to rotate through the action of friction.

[0037] like Figures 5 to 8 As shown, in order to prevent the winding roller 600 from overturning during the lifting process and ensure its lifting stability, there are two lifting devices 300, sliders 330, drive rollers 410 and drive motors 420. The two lifting devices 300, two sliders 330, two drive rollers 410 and two drive motors 420 are respectively arranged on the left and right sides of the base 100. The slider 330 and drive roller 410 on the left and the slider 330 and drive roller 410 on the right can respectively clamp the left and right ends of the winding roller 600; that is, the two sets of mechanisms are respectively located on the left and right sides, respectively lifting the left and right ends of the winding roller, and driving the winding roller 600 to rotate at the same time through the two drive rollers 410.

[0038] like Figure 3 As shown, in order to reduce the friction between the slider 330 and the winding roller 600, two lifting rollers 340 are rotatably connected to the slider 330, and the two lifting rollers 340 are spaced apart in the front-to-back direction. The two lifting rollers 340 can clamp the end of the winding roller 600 together with the driving roller 410; in step S200, when the slider 330 rises, the end of the winding roller 600 can be stuck in the gap between the two lifting rollers 340 and cannot pass through, so that the winding roller 600 rises together with the slider 330. Specifically, the sliders 330 at the left and right ends are provided with lifting rollers 340 with the same structure, and the winding roller 600 is lifted together at the left and right ends; of course, it is also possible to adopt a method of providing a bearing portion for bearing the end of the winding roller 600 on the slider 330 and coating the bearing portion with lubricating material to reduce friction.

[0039] like Figure 3 、 Figure 7 and Figure 8As shown, a first positioning portion 610 is provided on the winding roller 600, and the first positioning portion 610 can cooperate with the placement portion. A second positioning portion 620 is provided at the end of the winding roller 600, and the gap between the two lifting rollers 340 is smaller than the diameter of the second positioning portion 620. The diameter of the two lifting rollers 340 is equal to the diameter of the second positioning portion 620. The two lifting rollers 340 can clamp the second positioning portion 620 together with the driving roller 410; wherein, the two lifting rollers 340 and the second positioning portion 620 are both made of rigid materials. When the gap between the two lifting rollers 340 is smaller than the diameter of the second positioning portion 620, the slider 330 drives the two lifting rollers 340 to lift in step S200, which can drive the winding roller. The second positioning portion 620 at the end of 600 is lifted; specifically, the symmetry plane between the two lifting rollers 340 passes through the axis of the driving roller 410. When the two lifting rollers 340 and the driving roller 410 clamp the second positioning portion 620 together, since the diameter of the two lifting rollers 340 is equal to the diameter of the second positioning portion 620, the lowermost position of the driving roller 410 can abut against the second positioning portion 620. At the same time, the driving roller 410 does not rub against the two lifting rollers 340. In step S300, when the driving motor 420 drives the driving roller 410 to rotate, the driving roller 410 drives the second positioning portion 620 to rotate, and the two lifting rollers 340 rotate accordingly. There is no relative friction between the rollers, which effectively reduces the rotation resistance.

[0040] Specifically, in order to increase the friction between the driving roller 410 and the second positioning portion 620, the side wall of the driving roller 410 is provided with a friction pattern, wherein the friction pattern can increase the friction between the driving roller 410 and the second positioning portion 620 by increasing the roughness of the side wall of the driving roller 410.

[0041] like Figure 6 、 Figure 8 As shown, the first positioning portion 610 and the second positioning portion 620 are actually portions of the entire winding roller 600 that are slightly smaller in diameter than other portions, wherein the second positioning portions 620 at both ends are used to cooperate with the driving roller 410 to drive the entire winding roller 600 to rotate, while the first positioning portion 610 is used to cooperate with the V-shaped groove provided on the placement portion to ensure the stability of the position of the winding roller 600 relative to the transport vehicle 200 during the transportation process of the transport vehicle 200.

[0042] It can be understood that the transport vehicle 200 referred to in this embodiment is an AGV cart commonly used in industrial automation, which can transport materials to designated locations in a factory environment; two positioning platforms 210 are placed on the left and right edges of the transport vehicle 200, and the placement parts on the top of the two positioning platforms 210 respectively cooperate with the two first positioning parts 610 on a winding roller 600, thereby ensuring the stability of the winding roller 600 during the transportation process.

[0043] Specifically, in this embodiment, the driving roller 410 is preferably made of a steel frame and a soft wrapping material, and friction grooves are provided on the side walls of the soft wrapping material. In step S300, the soft wrapping material can be slightly deformed after being abutted by the second positioning portion 620, so as not to squeeze the lifting roller 340. At the same time, it can prevent the driving roller 410 from being damaged by excessive extrusion force due to the lifting error of the slider 330.

[0044] like Figure 2 、 Figure 4 As shown, the film material storage mechanism also includes an air supply device 500 arranged on the base 100, the air supply device 500 is located above the driving roller 410, the air inlet 510 of the air supply device 500 is connected to the heat pump system, the air outlet 520 of the air supply device 500 is downward, and an electric heater 521 is provided at the air outlet 520 of the air supply device 500; due to process requirements, during the process of winding and storing the film material, hot air needs to be blown to the film material to reduce the risk of breakage during the process of winding and storing the film material; therefore, in step S300, when controlling the driving motor 420 to drive the driving roller 410 to rotate, At the same time, the air supply device 500 is started to blow the hot air generated by the heat pump system toward the film material wound on the winding roller 600; wherein the air supply device 500 is preferably a cross-flow fan system, and its air inlet 510 is connected to the heat pump system, and the hot air generated by the heat pump system is pressurized and blown downwardly through the air outlet 520 to the wound film material, which can effectively reduce energy consumption. At the same time, the axial direction of the cross-flow fan system is arranged along the left and right directions, which can improve the uniformity of the hot air covering the film material in the left and right directions; at the same time, using a heat pump system to generate hot air can effectively reduce energy consumption compared to directly using an electric heating device to generate hot air.

[0045] Furthermore, in order to prevent the film material from being scratched and damaged during transportation after it is wound, in step S400, after the winding is completed, the film material is cut, and then the heat shrink film is wrapped around the wound film material for at least one circle, and then the drive motor 420 is controlled to drive the drive roller 410 to rotate, and at the same time the air supply device 500 and the electric heater 521 are turned on, so that the hot air blown out by the heat pump system is heated by the electric heater 521 and blown toward the heat shrink film, so that the heat shrink film shrinks and is fixed on the periphery of the wound film material, and then the control is turned on. The lifting device 300 drives the slider 330 to descend, so that the wound film roll falls onto the placement portion; since the temperature of the hot air blown out by the heat pump system is insufficient, the heat shrink film cannot be fully heated to shrink it, and the temperature of the hot air of the heat pump system rises slowly. Therefore, in the process of heating the heat shrink film, the electric heater 521 is turned on, so that the hot air blown out of the air outlet 520 is quickly heated, and the heat shrink film is quickly heated, so that the heat shrink film shrinks and covers the entire film roll; after the heat shrink film is completely shrunk, the electric heater 521 can be turned off.

[0046] In step S400, the heat shrink film can be manually fixed on the outside of the rolled film material, and then the drive motor 420 is controlled to drive the drive roller 410 to rotate at least one circle, so that the heat shrink film can be wrapped around the outer periphery of the film material roll.

[0047] During the transportation process in step S500, a protective layer formed by a heat shrink film is placed between the placement portion and the film material, which can effectively prevent the placement portion from scratching the film material and causing damage to the film material.

[0048] like Figure 1 As shown, the drive motor 420 is located on the outside of the vertical plate, and the drive roller 410 is located on the inside of the vertical plate. The drive motor 420 is connected to the drive roller 410 through a transmission box 430. A pulley transmission mechanism is provided in the transmission box 430, which can decelerate and increase the torque of the drive roller 410, thereby reducing the occurrence of slippage between the drive roller 410 and the second positioning part 620.

[0049] like Figure 3 As shown, the lifting device 300 includes: a lifting screw 310, which is rotatably set on the base 100, and the lifting screw 310 extends in the up and down directions, and the lifting slider 330 is threadedly engaged with the lifting screw 310; a lifting motor, which is set on the base 100, and the lifting motor is used to drive the lifting screw 310 to rotate; wherein the lifting motor is set in the cabinet below the lifting screw 310, and drives the slider 330 to rise and fall by driving the screw to rotate forward or reverse; in this embodiment, the lifting motor can be controlled to drive the screw to rotate a specified angle, so that the slider 330 can move up and down to the specified position, without the need to set a sensor to sense the lifting position of the slider 330, and the up and down position of the slider 330 can be controlled by open-loop control.

[0050] Specifically, in order to ensure the stability of the lifting and lowering of the slider 330, the lifting device 300 also includes a lifting guide rail 320, which is fixed on the base 100, and extends in the up and down directions. The lifting guide rail 320 and the slider 330 slide together; there are two guide rails, which are respectively arranged on the front and rear sides of the driving screw, and the slider 330 is limited on both sides to ensure the stability of the lifting and lowering of the slider 330.

[0051] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
