Description

Technical Field

[0001] This application relates to the field of membrane storage technology, specifically to a roll-up film three-dimensional storage device, a roll-up film transport trolley, and its operation method. Background Technology

[0002] With societal development, roll film is being used in various aspects of life, from ubiquitous snack bags to insulation materials for refrigerators and air conditioners. The demand for roll film is increasing everywhere, necessitating more efficient storage. However, existing storage devices use a flat, upright design, resulting in a high center of gravity and susceptibility to wobbling. This leads to poor stability during storage and the inability to stack the film, wasting valuable storage space and resulting in high costs. Furthermore, current technologies typically use forklifts for transporting roll film. Forklifts require professional operators, incur additional costs, and can easily cause deformation due to compression during operation and loading / unloading. Summary of the Invention

[0003] To address the problems in existing technologies where roll film storage on a flat surface results in a high center of gravity, making it prone to swaying and causing poor storage stability, and the inability to stack them leads to extremely high storage costs, this application provides a roll film three-dimensional storage device.

[0004] In order to solve the problems that the existing technology requires the use of mechanical forklifts to transport roll film, which requires professional personnel to operate, and the use of mechanical forklifts to transport roll film will incur additional costs and is also prone to damage to the roll film during operation and loading and unloading, this application provides a roll film transport trolley.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a roll film three-dimensional storage device, comprising: a support plate, a fixed shaft, and two rotating wheels. The number of support and fixed plates is two. The two ends of the fixed shaft are respectively mounted on the two support plates via bearings. The two rotating wheels are symmetrically arranged on both sides of the fixed shaft, and each rotating wheel is fixed to the fixed shaft. Each rotating wheel is provided with multiple shaft-stopping mechanisms, which are circumferentially distributed on the rotating wheel. Each rotating wheel includes an outer rotating wheel and an inner rotating wheel. The inner rotating wheel is fixed to the outer rotating wheel on the side away from the support plate. The outer rotating wheel is provided with multiple first holes, which are circumferentially arranged. The rotating inner wheel has multiple first grooves and multiple second holes distributed on the rotating outer wheel. The multiple first grooves and multiple second holes correspond one-to-one. The multiple first grooves are distributed circumferentially on the rotating inner wheel, and the diameter of the first groove is the same as the diameter of the film roll. One end of the second hole is aligned with the first hole, and the other end of the second hole is connected to the first groove. The size and shape of the second hole are the same as the first hole. The film roll is engaged in the first groove and extends into the second hole. The shaft-stopping mechanism is disposed on the outside of the rotating outer wheel. The shaft-stopping mechanism passes through the first hole in sequence and fixes the film roll in the second hole.

[0006] As a further improvement to the above solution, the first hole and the second hole are polygonal in shape, and the corresponding shaft-stopping mechanism is a polygonal structure.

[0007] As a further improvement to the above solution, the retaining shaft mechanism includes a pull ring and a retaining shaft body. The pull ring is installed on the retaining shaft body. The shape of the retaining shaft body is the same as the shape of the first hole. The retaining shaft body and the first hole are in clearance fit. The retaining shaft body is provided with a through hole for the film roller to be inserted. The retaining shaft body is inserted into the first hole and abuts against the second hole.

[0008] As a further improvement to the above solution, the rotating outer wheel is also provided with a stop mechanism and a fixing plate. One end of the fixing plate is fixed to the support plate, and the other end of the fixing plate is connected to the stop mechanism, which faces the rotating outer wheel. When the stop mechanism abuts against the rotating outer wheel, the rotating outer wheel is fixed by the stop mechanism and cannot rotate. When the stop mechanism separates from the rotating outer wheel, the rotating outer wheel can rotate.

[0009] As a further improvement to the above solution, a gear is fixed to the edge of the rotating outer wheel, and the stopping mechanism includes a housing, a right-angle clamp, and a locking member. The right-angle clamp penetrates the housing laterally and moves telescopically in the horizontal direction. The right-angle clamp is aligned with the gear of the rotating outer wheel and is adapted to be inserted into the gear to fix the rotating outer wheel. The locking member is adapted to limit the movement of the right-angle clamp.

[0010] As a further improvement to the above solution, a limiting retaining ring is provided between the rotating outer wheel and the support plate, and the limiting retaining ring is sleeved on the outside of the fixed shaft.

[0011] As a further improvement to the above solution, the rotating outer wheel is provided with a second groove, which is integrally formed by recessing from the outside of the rotating outer wheel inward. The second groove is a flower-shaped structure centered on the center of the rotating outer wheel. The support plate has a triangular structure and a third hole, which is also triangular. The shaft-stopping mechanism is adapted to pass through the third hole and be inserted into the first hole.

[0012] A roll film handling trolley includes a trolley body and two guide rails. The trolley body includes a base plate, a first handle, a second handle, two side plates, and two pairs of wheels. The two pairs of wheels are symmetrically mounted below the base plate. The two side plates are symmetrically fixed to the left and right sides above the base plate. The first handle and the second handle are respectively located on the front and rear sides above the base plate, with their lower ends rotatably mounted on the base plate. A third groove is provided on the side plate, and the roll film roller is adapted to be placed in the third groove. The two guide rails are symmetrically arranged below the aforementioned roll film three-dimensional storage device. The distance between the two guide rails is less than the distance between the two support plates. Each pair of wheels consists of two wheels, which are rotatably mounted within the two guide rails, allowing the wheels to drive the trolley body to move along the guide rails.

[0013] A method for storing a single roll of film in a roll-film stereoscopic storage device includes the following steps:

[0014] S1, first place the roll film into the third groove through the roll film roller, adjust the handle facing the roll film three-dimensional storage device to a horizontal position, and then push the roll film trolley so that the wheels of the roll film trolley move along the guide rail.

[0015] S2, manually move the rotating outer wheel through the second groove so that the two ends of the film rolling roller on the film rolling trolley are aligned with the first groove at the bottom of the rotating inner wheel on both sides. Then push the film rolling trolley so that the film rolling trolley and the rotating wheel can rotate together.

[0016] S3, when the film rolling trolley moves to the bottom of the rotating wheel, the film rolling roller is fully inserted into the first groove of the inner rotating wheel on both sides and extends into the second hole. Then, it passes through the first hole through the shaft blocking mechanism and clamps the film rolling roller in the second hole.

[0017] S4, then the outer wheel is rotated by the second groove, and the film rolling trolley is pushed out to complete the film rolling into the film three-dimensional storage device.

[0018] S5, after the roll film is stored and retrieved, the rotating outer wheel is fixed by the stop mechanism to keep the roll film three-dimensional storage device stationary.

[0019] A method for storing multiple rolls of film in a roll-film stereoscopic storage device includes the following steps:

[0020] S11, Remove the handles from the six film rolling trolleys, leaving only the second handle on the first film rolling trolley and the first handle on the sixth film rolling trolley. Use the connector to assemble the six film rolling trolleys into a whole, so that the six trolleys form a trolley group with handles only at the front and back.

[0021] S12, push the trolley group to the appropriate position of the three-dimensional storage device, adjust the handle of the first roll film operation trolley to the horizontal position, and push the wheels of the first roll film operation trolley into the guide rail.

[0022] S13, manually move the rotating outer wheel through the second groove so that the two ends of the film rolling roller on the first film rolling trolley are aligned with the first groove at the bottom of the rotating inner wheel on both sides, and then push the trolley group and rotate the rotating outer wheel.

[0023] S14, when the first film roll trolley moves to the bottom of the rotating wheel, the roll roller is fully engaged in the first groove of the inner rotating wheel on both sides and extends into the second hole. Then, it passes through the first hole through the shaft blocking mechanism and clamps the roll roller in the second hole.

[0024] S15, continue to push the trolley group and rotate the outer wheel, so that the film roller on the second film rolling trolley enters the first groove of the next inner wheel. When the second film rolling trolley moves to the bottom of the next inner wheel, the first film rolling trolley has moved along the guide rail to the other side of the three-dimensional storage device. At this time, the second film roller is locked by the shaft blocking mechanism.

[0025] S16, in sequence, to realize the storage of six rolls of film in the roll film three-dimensional storage device.

[0026] Compared with the prior art, the beneficial effects of this application are as follows:

[0027] (1) By setting multiple first grooves, multiple first holes and multiple second holes, multiple rolls of film can be stored between two support plates, and the rolls of film can be stacked and placed on the rotating wheel. Each roll of film will not come into contact with each other, which solves the problem that the existing technology uses flat standing placement of rolls of film, which wastes storage space and causes the cost of roll of film storage to rise sharply.

[0028] (2) By setting the shaft stop mechanism, the shaft stop mechanism can lock the film roll into the first groove, prevent the film roll from falling out of the first groove, improve the stability of the film roll installed on the rotating wheel, and when disassembling the film roll, it is only necessary to pull out the shaft stop mechanism to achieve disassembly. The entire installation, fixing and disassembly process is very simple and has a good fixing effect on the film roll.

[0029] (3) By setting up a roll film transport trolley, the use of mechanical forklifts to transport roll film in the prior art can be effectively replaced. The roll film transport trolley is easy to operate and does not require professional personnel to operate, which greatly reduces the transportation cost. Moreover, the roll film transport trolley of this application will not squeeze the roll film during the transportation process, thus protecting the roll film during the transportation process.

[0030] (4) The method provided in this application for storing roll film in a three-dimensional storage device by means of a roll film transport trolley can realize the rapid storage of roll film. The whole storage process is simple to operate, has a good storage effect, and is convenient to disassemble later. Attached Figure Description

[0044] Reference Figure 1-10As shown, one embodiment of this application provides a roll film three-dimensional storage device, which includes: a support plate 9, a fixed shaft 3, and two rotating wheels 7. There are two support plates 9. The two ends of the fixed shaft 3 are respectively mounted on the two support plates 9 through bearings 8. The two rotating wheels 7 are symmetrically arranged on both sides of the fixed shaft 3. Each rotating wheel 7 is fixed on the fixed shaft 3. The fixed shaft 3 and the support plate 9 are mounted by bearings 8, and the rotating wheels 7 and the fixed shaft 3 are fixedly connected. This allows the fixed shaft 3 to drive the two rotating wheels 7 to rotate while the support plate 9 does not rotate, ensuring the stability of the fixed shaft 3 and the rotating wheels 7 during rotation. The rotating wheel 7 is provided with multiple shaft-blocking mechanisms 6, which are circumferentially distributed on the rotating wheel 7. The rotating wheel 7 includes an outer rotating wheel 71 and an inner rotating wheel 72. The inner rotating wheel 72 is fixed to the side of the outer rotating wheel 71 away from the support plate 9. The outer rotating wheel 71 is provided with multiple first holes 711, which are circumferentially distributed on the outer rotating wheel 71. The inner rotating wheel 72 is provided with multiple first grooves 721 and multiple second holes 722, which correspond one-to-one. The first grooves 721 are circumferentially distributed on the inner rotating wheel 72. The diameter of the first grooves 721 is the same as the diameter of the film roll 51. By setting multiple first grooves 721, multiple rolls of film 5 can be three-dimensionally installed on the rotating wheel 7, and the rolls of film 5 can be stacked through the rotating wheel 7. This effectively solves the problem in the prior art where the rolls of film 5 are placed flat and upright, wasting storage space and causing a sharp increase in the storage cost of the rolls of film 5. One end of the second hole 722 is aligned with the first hole 711, and the other end of the second hole 722 is connected to the first groove 721. The size and shape of the second hole 722 are the same as those of the first hole 711. The film roll 51 is engaged with the first groove 721 and extends into the second hole 722. The shaft-stopping mechanism 6 is located on the outside of the rotating outer wheel 71. The shaft-stopping mechanism 6 passes through the first hole 711 and fixes the film roll 51 in the second hole 722. In actual operation, the film roll 5 needs to be stored. When the film roll 51 is fully inserted into the first groove 721, the outer side of the film roll 51 will pass through the first groove 721 and extend into the second hole 722. Then, the shaft stop mechanism 6 is inserted through the first hole 711 and into the second hole 722. Thus, the shaft stop mechanism 6 can limit the film roll 51, so that the film roll 51 can be engaged in the first groove 721, thereby realizing the storage of the film roll 5.

[0045] like Figure 2 and Figure 3 As shown, both the outer rotating wheel 71 and the inner rotating wheel 72 have a certain thickness, and the outer rotating wheel 71 and the inner rotating wheel 72 are welded together.

[0046] like Figure 3 As shown, preferably, there are 6 first grooves 721 on one side of the rotating inner wheel 72. The 6 first grooves 721 are distributed circumferentially on the rotating inner wheel 72. Setting 6 first grooves 721 can prevent the edge of the film 5 from being squeezed and deformed when two adjacent film 5s are stored, while stacking and installing the film 5, thus improving its stability during storage.

[0047] like Figure 3-5 As shown, the first hole 711 and the second hole 722 are polygonal in shape, and the corresponding shaft-stopping mechanism 6 is also polygonal in structure. When the shaft-stopping mechanism 6 passes through the first hole 711 and is inserted into the second hole 722, the shaft-stopping mechanism 6 can limit the film roller 51, prevent it from falling out of the first groove 721, and improve the stability of the film roller 51 installed on the rotating wheel 7.

[0048] like Figure 1-2 As shown, the shaft retaining mechanism 6 includes a pull ring 61 and a shaft retaining body 62. The pull ring 61 is installed on the shaft retaining body 62. The shape of the shaft retaining body 62 is the same as that of the first hole 711. The shaft retaining body 62 and the first hole 711 are in clearance fit. The clearance fit allows the shaft retaining body 62 to pass through the first hole 711 and be inserted into the second hole 722. The retaining shaft body 62 is provided with a locking hole 63 for inserting the film roller 51. In actual operation, the film roller 51 is first inserted into the first groove 721. After the film roller 51 is fully inserted into the first groove 721, the locking hole 63 is aligned with the film roller 51, and the retaining shaft body 62 is pushed through the first hole 711 and inserted into the second hole 722 by the pull ring 61. Thus, the film roller 51 is inserted into the locking hole 63, thereby realizing the retaining shaft mechanism 6 to limit the film roller 51, preventing it from falling out of the first groove 721 and improving the stability of the film roller 51 installed on the film three-dimensional storage device.

[0049] like Figure 1 As shown, the locking hole 63 can be circular, and the film roller 51 can also be circular, making it easy for the film roller 51 to be inserted into the locking hole 63. At the same time, in conjunction with the polygonal structure of the retaining shaft body 62 and the polygonal structure of the first hole 711 and the second hole 722, the film roller 51 can be fixed between the two rotating wheels 7, achieving the purpose of limiting and fixing it, and improving its stability during storage. At the same time, since the locking hole 63 is circular and the film roller 51 is also circular, the film roller 51 can rotate within the locking hole 63. That is, the retaining shaft mechanism 6 of this application can limit the film roller 51 between the two rotating wheels 7.

[0050] In addition, the film roller 51 can also be a quadrilateral or polygonal structure. At the same time, the locating hole 63 also needs to be set as a quadrilateral or polygonal structure so that the film roller 51 can be inserted into the locating hole 63. However, in this case, the film roller 51 cannot rotate in the locating hole 63. Therefore, the shaft blocking mechanism 6 under this structure can not only limit the film roller 51 between the two rotating wheels 7, but also prevent the film roller 51 itself from rotating.

[0051] like Figure 1-2 As shown, the rotating outer wheel 71 is also provided with a stop mechanism 2 and a fixing plate 1. One end of the fixing plate 1 is fixed to the support plate 9, and the other end of the fixing plate 1 is connected to the stop mechanism 2. The stop mechanism 2 faces the rotating outer wheel 71. When the stop mechanism 2 abuts against the rotating outer wheel 71, the rotating outer wheel 71 is fixed by the stop mechanism 2 and cannot rotate. When the stop mechanism 2 is separated from the rotating outer wheel 71, the rotating outer wheel 71 can rotate. Understandably, when the roll film 5 needs to be stored, the rotating outer wheel 71 needs to be able to rotate. Therefore, in the actual operation, the stop mechanism 2 needs to be operated first to separate the stop mechanism 2 from the rotating outer wheel 71 before the roll film 5 can be stored. After the roll film 5 storage operation is completed and the rotating outer wheel 71 comes to a stop, the stop mechanism 2 is activated to abut against the rotating outer wheel 71, thereby fixing the rotating outer wheel 71. By setting the stop mechanism 2, the rotation of the rotating wheel 71 is prevented from rotating after storage, which can improve the stability of the entire roll film three-dimensional storage device during the storage process.

[0052] like Figure 1-2As shown, a gear 712 is fixed to the edge of the rotating outer wheel 71. The stopping mechanism 2 includes a housing 21, a right-angle clamp 22, and a locking member 23. The right-angle clamp 22 extends laterally through the housing 21 and moves horizontally. The right-angle clamp 22 is aligned with the gear 712 of the rotating outer wheel 71. The right-angle clamp 22 is suitable for inserting the gear 712 to fix the rotating outer wheel 71. The locking member 23 is suitable for limiting the movement of the right-angle clamp 22. Specifically, a spring is provided inside the housing 21. The spring is sleeved on the outside of the right-angle clamp 22. The elastic force of the spring is suitable for driving the right-angle clamp 22 to move horizontally. The locking element 23 can be a pin, and the right-angle clip 22 is provided with multiple insertion holes arranged in sequence along the horizontal direction. The pin is suitable for passing through the insertion holes and abutting against the housing 21. In actual operation, if the stop mechanism 2 is required to limit and fix the rotating outer wheel 71, the locking element 23 can be pulled up first. Under the spring force, the right-angle clip 22 can be inserted into the gear 712 along the horizontal direction. Then, the locking element 23 is passed through the mounting hole on the housing 21 and inserted into the insertion hole, thereby realizing the operation of the stop mechanism 2 to limit and fix the rotating outer wheel 71. When the roll film 5 needs to be stored or disassembled, the stop mechanism 2 must first be separated from the gear 712 on the rotating outer wheel 71. The separation process is as follows: first, remove the locking member 23 from the housing 21, then pull the right-angle clip 22 away from the rotating outer wheel 71, so that the right-angle clip 22 is away from the gear 712. Then, insert the locking member 23 into the housing 21 and pass through the insertion hole to limit the right-angle clip 22, thereby separating the right-angle clip 22 from the gear 712, thus realizing the rotation of the rotating wheel 7.

[0053] like Figure 2 As shown, a retaining ring 4 is provided between the rotating outer wheel 71 and the support plate 9. The retaining ring 4 is sleeved on the outside of the fixed shaft 3. By placing the retaining ring 4 between the rotating outer wheel 71 and the support plate 9, rubbing between the shaft-blocking mechanism 6 and the support plate 9 can be prevented. Specifically, one end of the retaining ring 4 is fixed to the rotating outer wheel 71, and the other end of the retaining ring 4 has a gap with the bearing 8 installed in the support plate 9. This installation method can ensure the stability of the retaining ring 4 and prevent it from shaking.

[0054] The rotating outer wheel 71 is provided with a second groove 713, which is integrally formed by recessing from the outside of the rotating outer wheel 71 inward. The second groove 713 is a flower-shaped structure centered on the center of the rotating outer wheel 71. By providing the second groove 713, not only can the weight be reduced, but the rotating outer wheel 71 can also be rotated manually.

[0055] like Figure 2As shown, the support plate 9 has a triangular structure, which can improve the stability of the support plate 9 supporting the rotating wheel 7. The support plate 9 is provided with a third hole 91. The third hole 91 has a triangular structure, which can not only reduce the weight of the support plate 9, but also facilitate the shaft blocking mechanism 6 to pass through the third hole 91 and be inserted into the first hole 711.

[0056] like Figure 2 As shown, the lower end of the support plate 9 is provided with screw holes, so that the support plate 9 can be fixed to the warehouse floor by passing anchor bolts through the screw holes.

[0057] During the installation of the roll film 5, it needs to be handled. In existing technologies, this is generally done using a forklift. However, using a forklift requires professional operators, which significantly increases the cost of the entire roll film 5 storage process. Furthermore, handling the roll film 5 with a forklift can easily cause compression and deformation. Figure 6-10As shown, this application provides a roll film transport trolley 10, which includes a trolley body and two guide rails 11. The trolley body includes a base plate 101, a first handle 102, a second handle 103, two side plates 104, and two pairs of wheels 105. The two pairs of wheels 105 are symmetrically installed below the base plate 101, and the two side plates 104 are symmetrically fixed to the left and right sides above the base plate 101. The first handle 102 and the second handle 103 are respectively located on the front and rear sides above the base plate 101. By setting the first handle 102 and the second handle 103, the roll film transport trolley 10 can be pulled from the front and rear ends respectively, improving the convenience of transporting the roll film. The lower ends of the first handle 102 and the second handle 103 are rotatably mounted on the base plate 101. The rotatable mounting method allows the first handle 102 and the second handle 103 to be placed in a horizontal state and pass through the roll film three-dimensional storage device. Specifically, handle 102 and handle 2 103 are respectively fixed to the base plate 101 of the trolley body with bolts. The bolt fixing allows for pushing and pulling of the film-rolling trolley 10 using the handles, and the direction of pushing and pulling can be controlled by adjusting the angle between handle 102 and handle 2 103 and the base plate 101. Furthermore, when the film-rolling trolley 10 enters the film-rolling storage device, handle 102 or handle 2 103 can be placed horizontally to facilitate its passage through the storage device. The side plate 104 has a third groove 106, in which the film-rolling roller 51 is adapted to be placed. The third groove 106 supports the film-rolling roller 51, which extends beyond the side plate 104 by a certain thickness. Two guide rails 11 are symmetrically arranged below the above-mentioned roll film storage device. The distance between the two guide rails 11 is less than the distance between the two support plates 9. There are two wheels 105. The two wheels 105 are respectively rolled and installed in the two guide rails 11. The wheels 105 can drive the trolley body to move along the guide rails 11, so that the wheels 105 on the roll film moving trolley 10 are suitable for moving along the guide rails 11 from one side of the roll film storage device to the other side and placing the roll film 5 on the roll film moving trolley 10 into the roll film storage device.

[0058] The roll film transport trolley 10 in this application can be assembled. During the assembly process, handle 102 or handle 2103 can be retained as appropriate. Multiple roll film transport trolleys 10 can be assembled into a trolley group, thereby enabling the transport of multiple rolls of film.

[0059] like Figure 6-9 As shown, a method for storing a single roll of film in a roll-film stereoscopic storage device is characterized by comprising the following steps:

[0060] S1. First, place the roll film into the third groove through the roll film roller. Adjust the handle facing the roll film three-dimensional storage device to a horizontal position. Then, push the roll film trolley so that the wheels of the roll film trolley can move along the guide rail.

[0061] S2, manually move the rotating outer wheel through the second groove so that the two ends of the film rolling roller on the film rolling trolley are aligned with the first groove at the bottom of the rotating inner wheel on both sides. Then push the film rolling trolley so that the film rolling trolley and the rotating wheel can rotate together.

[0062] S3, when the film rolling trolley moves to the bottom of the rotating wheel, the film rolling roller is fully inserted into the first groove of the inner rotating wheel on both sides and extends into the second hole. Then, it passes through the first hole through the shaft blocking mechanism and clamps the film rolling roller in the second hole.
