Description

Technical Field

[0001] This disclosure belongs to the field of covering technology, and specifically relates to an automatic canvas retraction and deployment system and method. Background Technology

[0002] In outdoor production and daily life, canvas is frequently used to cover products or provide shade. However, the unfolding and folding of canvas often relies on manual labor; either the canvas is pulled open or folded manually. For large areas of canvas, such as those used to cover coal mines, this method of unfolding and folding is labor-intensive and inefficient. Summary of the Invention

[0003] This disclosure provides an automatic canvas deployment and take-up system and method, which can improve the efficiency of canvas deployment and take-up. The technical solution is as follows:

[0004] This disclosure provides an automatic canvas loading and unloading system. The system includes a canvas storage box, a lifting assembly, and a guiding assembly. The canvas storage box has an opening at the top and is used to store canvas stacked along its height. In the storage box, every two adjacent layers of canvas are connected to form a U-shaped structure. The opening direction of the U-shaped structure is perpendicular to the height direction of the storage box, and the opening directions of two adjacent U-shaped structures are opposite. The U-shaped structure located at the opening and being the topmost layer is the target U-shaped structure. When loading or unloading the canvas, the topmost layer of canvas in the target U-shaped structure can... Under the action of external force, it moves within the opening along the opening direction; the lifting assembly is located inside and connected to the canvas storage box, and is used to drive the canvas inside the canvas storage box to rise and fall along the height direction of the canvas storage box; the guiding assembly includes a translation drive and a guide, the translation drive is connected to the canvas storage box, the guide is located at the opening and within the target U-shaped structure, the guide is attached to the end of the target U-shaped structure away from its own opening, and the guide is configured to move synchronously with the target U-shaped structure along the opening direction of the target U-shaped structure under the drive of the translation drive.

[0005] In another implementation of this disclosure, the translation drive component includes a translation drive motor and a translation drive rod; the translation drive motor is connected to the translation drive rod, the translation drive motor is used to drive the translation drive rod to rotate, the middle part of the translation drive rod is inserted into the guide and threadedly connected to the guide, and the length direction of the translation drive rod is the opening direction.

[0006] In another implementation of this disclosure, there are two guide components, which are located on opposite sides of the canvas storage box along a length direction perpendicular to the translation drive rod.

[0007] In another implementation of this disclosure, the lifting assembly includes a lifting drive rod and a lifting platform. One end of the lifting drive rod is connected to the bottom of the canvas storage box, and the other end of the lifting drive rod is located in the opening. The length direction of the lifting drive rod is the height direction of the canvas storage box. The lifting platform is connected to the lifting drive rod, and the lifting drive rod is used to drive the lifting platform to move along the length direction of the lifting drive rod. The canvas is located on the lifting platform.

[0008] In another implementation of this disclosure, the lifting assembly further includes a plurality of guide rods, which are spaced apart on the outer periphery of the lifting platform. Each guide rod is parallel to the lifting drive rod. The bottom of the guide rod is connected to the canvas storage box, the top of the guide rod is located in the opening, and the middle of the guide rod is slidably connected to the lifting platform.

[0009] In another implementation of this disclosure, the automatic canvas take-up and take-down system further includes a pressing component, at least a portion of which is located inside and connected to the canvas storage box. The pressing component is used to limit and press the other layers of canvas within the canvas storage box when the two layers of canvas in the target U-shaped structure move.

[0010] In another implementation of this disclosure, the clamping assembly includes a clamping plate and a driving unit. The clamping plate and the driving unit are connected, and the driving unit is configured to drive the clamping plate to switch between a first position and a second position. When the clamping plate is in the first position, the clamping plate is located inside the canvas storage box, and at least a portion of the clamping plate is located inside the quasi-target U-shaped structure and is abutted against the end of the quasi-target U-shaped structure away from its own opening. The quasi-target U-shaped structure is located below the target U-shaped structure. When the clamping plate is in the second position, the clamping plate is located outside the quasi-target U-shaped structure.

[0011] In another implementation of this disclosure, the drive unit includes a rotary drive motor and a transmission gear set; the rotary drive motor is connected to the outer wall of the canvas storage box, the transmission gear set is connected to the output shaft of the rotary drive motor, the output gear shaft of the transmission gear set is connected to the pressure plate, the output gear shaft of the transmission gear set is parallel to the output shaft of the rotary drive motor, and the axial direction of the output gear shaft is the same as the height direction of the canvas storage box.

[0012] In another implementation of this disclosure, there are two clamping components, which are located on opposite sides of the canvas along a direction perpendicular to the opening.

[0013] In another implementation of this disclosure, an automatic canvas retraction and deployment method is also provided. The automatic canvas retraction and deployment method is implemented by the above-described automatic canvas retraction and deployment system. The automatic canvas retraction and deployment method includes: using a lifting component in the automatic canvas retraction and deployment system to position a target U-shaped structure in an opening; placing a guide component in the automatic canvas retraction and deployment system inside the target U-shaped structure, such that the guide component is in contact with the end of the target U-shaped structure away from its opening; and controlling the guide component and the top layer of canvas in the target U-shaped structure to move back and forth synchronously along the opening direction.

[0014] The beneficial effects of the technical solutions provided in this disclosure are:

[0015] When the automatic canvas storage and take-up system provided in this embodiment is used to store canvas, the system includes a canvas storage box with an opening at the top, providing storage space for the canvas. Furthermore, during storage and take-up, the canvas can be placed into the storage box through the opening, and when unfolded, it can be removed from the storage box through the opening.

[0016] Because the automatic canvas storage and unfolding system also includes a guiding component, which comprises a translational drive and a guide member, the guide member is located within the target U-shaped structure. The guide member is abutted against the end of the target U-shaped structure furthest from its opening, and is configured to move synchronously with the target U-shaped structure along the opening direction under the drive of the translational drive. This allows the guide member to move synchronously with the target U-shaped structure within the opening during canvas storage, ensuring the target U-shaped structure completely fills the opening. When the canvas is stacked on top of other U-shaped structures, the target U-shaped structure can be moved out of the opening when the canvas is unfolded. Furthermore, since the automatic canvas storage and unfolding system also includes a lifting component, which drives the canvas to move up and down along the height of the canvas storage box, when the target U-shaped structure fills the opening during canvas storage, the lifting component can lower the U-shaped structure to create space for further canvas storage. Alternatively, when the canvas is unfolded, after the target U-shaped structure moves out of the opening, the lifting component can be used to move the canvas in the canvas storage box upwards, so that the canvas under the original target U-shaped structure forms a new target U-shaped structure, which can then be unfolded outside the canvas storage box.

[0017] In other words, by combining the lifting and guiding components, the canvas can be stacked sequentially, and when unfolded, it can be easily unfolded along the stacking direction without getting messy, greatly improving the efficiency of unfolding and retracting. Attached Figure Description

[0031] 100. Canvas. Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0033] This disclosure provides an automatic canvas deployment and retraction system for automatically deploying and retracting canvas (e.g., canvas covering an open coal bunker).

[0034] Figure 1 This is a schematic diagram of the automatic canvas take-up and take-down system provided in the embodiments of this disclosure, as shown below. Figure 1 As shown, the automatic canvas storage and take-up system includes a canvas storage box 1, a lifting assembly 2, and a guiding assembly 3. The top of the canvas storage box 1 has an opening 10, and the canvas storage box 1 is used to store canvases 100 stacked along the height direction of the canvas storage box 1.

[0035] In the canvas storage box 1, every two adjacent layers of canvas 100 are connected to form a U-shaped structure. The opening direction of the U-shaped structure is perpendicular to the height direction of the canvas storage box 1, and the opening directions of two adjacent U-shaped structures are opposite. The U-shaped structure located at the opening 10 and being the topmost layer is the target U-shaped structure 101. When the canvas is being unfolded or retracted, the topmost layer of canvas in the target U-shaped structure 101 can move along the opening direction under the action of external force ( Figure 1 a) Move within opening 10 in the direction of the middle.

[0036] The lifting assembly 2 is located inside and connected to the canvas storage box 1. The lifting assembly 2 is used to drive the canvas 100 inside the canvas storage box 1 to move up and down along the height direction of the canvas storage box 1. The guide assembly 3 includes a translation drive 31 and a guide 33. The translation drive 31 is connected to the canvas storage box 1. The guide 33 is located at the opening 10 and inside the target U-shaped structure 101. The guide 33 is attached to the end of the target U-shaped structure 101 away from its own opening. The guide 33 is configured to move synchronously with the target U-shaped structure 101 along the opening direction of the target U-shaped structure 101 under the drive of the translation drive 31.

[0037] When the automatic canvas storage and unfolding system provided in this embodiment of the present disclosure is used to store and unfold the canvas, since the automatic canvas storage and unfolding system includes a canvas storage box 1 and the top of the canvas storage box 1 has an opening 10, the canvas storage box 1 can provide storage space for the canvas. Furthermore, when the canvas is being stored or unfolded, it can enter the canvas storage box 1 through the opening 10 for storage, and when the canvas is unfolded, it can also be removed from the canvas storage box 1 through the opening 10.

[0038] Because the automatic canvas unfolding and retracting system also includes a guide assembly 3, which includes a translation drive 31 and a guide 33, the guide 33 is located inside the target U-shaped structure 101. The guide 33 is attached to the end of the target U-shaped structure 101 away from its opening, and is configured to move synchronously with the target U-shaped structure 101 along the opening direction under the drive of the translation drive 31. In this way, when the canvas is being retracted, the guide 33 can move synchronously with the target U-shaped structure 101 in the opening 10, so that the target U-shaped structure 101 fills the opening 10 and is then stacked on top of other U-shaped structures during the canvas retraction process. Alternatively, when the canvas is unfolded, the target U-shaped structure 101 can be moved out of the opening 10. Furthermore, since the automatic canvas unfolding system also includes a lifting component 2, which drives the canvas 100 to move up and down along the height of the canvas storage box 1, when the canvas is being stored, once the target U-shaped structure 101 has filled the opening 10, the lifting component 2 can move the U-shaped structure down to make room for further canvas storage. Alternatively, when the canvas is unfolding, after the target U-shaped structure 101 has moved out of the opening 10, the lifting component 2 can move the canvas inside the canvas storage box 1 up, causing the canvas below the original target U-shaped structure 101 to move up and form a new target U-shaped structure 101, which can then continue to unfold outside the canvas storage box 1.

[0039] In other words, through the cooperation of the lifting component 2 and the guiding component 3, the canvas can be stacked sequentially to form a U-shaped structure, and when unfolded, it can also unfold in the direction of stacking without getting messy, greatly improving the efficiency of unfolding and retracting.

[0040] In this embodiment, the canvas needs an external power structure, such as a hand pull or a motor, to apply force to the canvas during its unfolding and retraction so that the canvas can move horizontally.

[0041] Optionally, the canvas storage box 1 is a cuboid structure with an opening at the top. The canvas storage box 1 includes a base plate 11 and four side plates 12. The four side plates 12 are located on the same surface of the base plate 11 and are vertically connected to the four sides of the base plate 11. An opening 10 is formed on the side of each side plate 12 away from the base plate 11. This allows for a simple construction of the canvas storage box 1 to provide a base for receiving the canvas 100.

[0042] The connection between the base plate 11 and the side plate 12 can be achieved by welding or by other fasteners such as bolts.

[0043] Figure 2 yes Figure 1 The left view, combined with Figure 2 Optionally, the lifting assembly 2 includes a lifting drive rod 21 and a lifting platform 22. One end of the lifting drive rod 21 is connected to the bottom of the canvas storage box 1, and the other end of the lifting drive rod 21 is located in the opening 10. The length direction of the lifting drive rod 21 is the height direction of the canvas storage box 1.

[0044] The lifting platform 22 is connected to the lifting drive rod 21, and the lifting drive rod 21 is used to drive the lifting platform 22 to move along the length direction of the lifting drive rod 21. The canvas 100 is located on the lifting platform 22.

[0045] In the above implementation, the lifting drive rod 21 is used to drive the lifting platform 22 to move up and down relative to the canvas storage box 1. The lifting platform 22 is used to support the canvas 100 so that the canvas can be raised and lowered as a whole.

[0046] In this embodiment, the outer wall of the lifting drive rod 21 has threads, and the lifting platform 22 has a threaded hole that matches the threads on the outer wall of the lifting drive rod 21. By rotating the lifting drive rod 21, the lifting platform 22 can be raised or lowered relative to the canvas storage box 1.

[0047] To facilitate the rotation of the lifting drive rod 21, the lifting assembly 2 also includes a lifting drive motor 211, which is connected inside the canvas storage box 1. The output end of the lifting drive motor 211 is connected to one end of the lifting drive rod 21. In this way, by controlling the working state of the lifting drive motor 211, the rotation of the lifting drive rod 21 can be controlled, thereby controlling the lifting and lowering of the lifting platform 22.

[0048] The canvas storage box 1 also includes an L-shaped support plate 13, which is connected to the base plate 11 of the canvas storage box 1. The lifting drive motor 211 is connected to the L-shaped support plate 13. This facilitates the installation and fixation of the lifting drive motor 211.

[0049] In other examples, the lifting drive rod 21 and the lifting platform 22 can be replaced with other structures. For example, the lifting drive rod 21 can be a hydraulic cylinder, with its piston rod connected to the bottom of the lifting platform 22. By controlling the extension and retraction of the piston rod, the lifting platform 22 can also be raised and lowered.

[0050] Compared to hydraulic cylinders and other drive components, the lifting drive motor 211 occupies less space and is easier to connect and fix. As long as the lifting platform 22 can be raised and lowered relative to the canvas storage box 1 without affecting the use of other components, the driving method of the lifting drive rod 21 can be any form, and this disclosure does not impose any restrictions on it.

[0051] Optionally, the lifting assembly 2 also includes a plurality of guide rods 23, which are spaced apart on the outer periphery of the lifting platform 22, and each of the guide rods 23 is parallel to the lifting drive rod 21. The bottom of the guide rod 23 is connected to the bottom of the canvas storage box 1, the top of the guide rod 23 is located in the opening 10, and the middle part of the guide rod 23 is slidably connected to the lifting platform 22.

[0052] In the above implementation, the guide rod 23 is used to limit the lifting direction of the lifting platform 22, so that the lifting platform 22 will not deviate during lifting, but can only move along the length direction of the guide rod 23.

[0053] Figure 3 yes Figure 1 Top view, combined Figure 3 In this embodiment, there are two lifting drive rods 21, which are arranged at intervals and are symmetrical about the center of the lifting platform 22. The axis of the line connecting the two lifting drive rods 21 is the axis of symmetry of the lifting platform 22. Both lifting drive rods 21 are located on the outer periphery of the canvas inside the canvas storage box 1. Each lifting drive rod 21 is connected to a corresponding lifting drive motor 211. This allows the lifting drive rods 21 to be symmetrically distributed on both sides of the lifting platform 22, so that the supporting force of each lifting drive rod 21 on the lifting platform 22 is the same, ensuring that the lifting platform 22 will not tilt.

[0054] In other examples, the number of lifting drive rods 21 can also be other numbers, such as three, four, etc.

[0055] In this embodiment, there are four guide rods 23, located at the four corners of the lifting platform 22, and all four guide rods 23 are situated around the canvas inside the canvas storage box 1. Two of the guide rods 23 are aligned with the first lifting drive rod 21, with the first rod located on either side of the lifting drive rod 21. The other two guide rods 23 are aligned with the second lifting drive rod 21, with the second rod located on either side of the lifting drive rod 21. This arrangement ensures that both the lifting drive rod 21 and the guide rods 23 are located on the outer periphery of the lifting platform 22, preventing interference with the canvas on the lifting platform 22.

[0056] Figure 4 yes Figure 3 Enlarged view of point B in the image, combined with Figure 4Optionally, the translation drive component 31 includes a translation drive motor 311 and a translation drive rod 312. The translation drive motor 311 is connected to the translation drive rod 312 and is used to drive the translation drive rod 312 to rotate. The middle part of the translation drive rod 312 is inserted into the guide member 33 and is threadedly connected to the guide member 33. The length direction of the translation drive rod 312 is the opening direction.

[0057] In the above implementation, the translation drive motor 311 is used to drive the translation drive rod 312 to rotate, and the guide member 33 is used to move along the length direction of the translation drive rod 312 when the translation drive rod 312 rotates. This allows the guide member 33 to move synchronously with the target U-shaped structure 101, thereby guiding the target U-shaped structure 101 to fill the opening 10 and be stacked in the canvas storage box 1, or guiding the target U-shaped structure 101 to move out of the opening 10, so that the canvas is unfolded from the canvas storage box 1.

[0058] The translation drive motor 311 is connected to one of the side plates 12 of the canvas storage box 1 via a connecting plate 313. The connecting plate 313 is welded perpendicularly to the connected side plate 12. The translation drive motor 311 is connected to the connecting plate 313 by bolts or other fasteners. The output shaft of the translation drive motor 311 is perpendicular to the connecting plate 313. This allows for easy and simple fixing of the translation drive motor 311 to the outside of the canvas storage box 1.

[0059] In this embodiment, the translation drive rod 312 is a screw, and the guide member 33 has an internal threaded hole, which is threadedly connected to the screw. Thus, when the translation drive rod 312 rotates, the guide member 33 can move along the length of the translation drive rod 312.

[0060] The output shaft of the translation drive motor 311 is connected to one end of the translation drive rod 312 via a coupling. The other end of the translation drive rod 312 is rotatably connected to one side plate of the canvas storage box 1 via bearings or the like.

[0061] To facilitate a good fit between the guide member 33 and the target U-shaped structure 101, the guide member 33 can be a cylindrical structure. The axial direction of the cylindrical structure of the guide member 33 is perpendicular to the axis of the internal threaded hole.

[0062] In other examples, the guide component 3 can also be other structures, such as a hydraulic cylinder set outside the canvas storage box 1. The piston rod of the hydraulic cylinder is connected to the guide component 33. By controlling the extension and retraction of the piston rod of the hydraulic cylinder, the guide component 33 can also follow the target U-shaped structure 101.

[0063] Combination Figure 3 and Figure 4Optionally, there are two guide components 3, which are located on opposite sides of the canvas storage box 1 along the length direction perpendicular to the translation drive rod 312.

[0064] In the above implementation, two guide components 3 are set up to guide and push the opposite sides of the target U-shaped structure 101, thereby improving the efficiency of the canvas 100's unfolding and retraction.

[0065] In other examples, instead of two guide components 3, only one guide component 3 may be used. However, in the direction perpendicular to the length of the translation drive rod 312, the length of the guide member 33 in the guide component 3 shall not be less than half the width of the target U-shaped structure 101. For example, the length of the guide member 33 in the guide component 3 shall be 2 / 3 of the width of the target U-shaped structure 101. That is, the guide member 33 can extend to the opposite sides of the target U-shaped structure 101. This also prevents the target U-shaped structure 101 from curling or other abnormalities, and instead allows it to be translated and stacked to form a U-shaped structure, which is then placed inside the canvas storage box 1 or unfolded smoothly.

[0066] See you again Figure 1 and Figure 2 Optionally, the automatic canvas take-up and take-down system also includes a clamping assembly 4, at least a portion of which is located inside and connected to the canvas storage box 1. The clamping assembly 4 is used to limit and clamp the other layers of canvas inside the canvas storage box 1 when the two layers of canvas in the target U-shaped structure 101 move.

[0067] In the above implementation, the clamping component 4 is used to ensure that the canvas below the target U-shaped structure 101 does not move with the target U-shaped structure 101, but is firmly fixed in the canvas storage box 1, so as to improve the efficiency of canvas loading and unloading.

[0068] In other examples, the canvas below the target U-shaped structure can also be pressed down manually to keep it stationary.

[0069] Optionally, the clamping assembly 4 includes a clamping plate 41 and a drive unit 42, the clamping plate 41 and the drive unit 42 being connected, and the drive unit 42 being configured to drive the clamping plate 41 to switch between a first position and a second position.

[0070] When the clamping plate 41 is in the first position (that is...) Figure 1 When in the position shown, the clamping plate 41 is located inside the canvas storage box 1, and at least a portion of the clamping plate 41 is located inside the quasi-target U-shaped structure 102, and is abutting against the end of the quasi-target U-shaped structure 102 away from its own opening. The quasi-target U-shaped structure 102 is located below the target U-shaped structure 101. When the clamping plate 41 is in the second position, the clamping plate 41 is located outside the quasi-target U-shaped structure 102.

[0071] In the above implementation, by setting the clamping plate 41, the clamping plate 41 can be located inside the target U-shaped structure 102, so that the canvas below the target U-shaped structure 101 will not move with the target U-shaped structure 101.

[0072] The drive unit 42 is used to drive the pressure plate 41 to freely switch between the first position and the second position, so as to adjust the position of the pressure plate 41 at any time as needed, so that the pressure plate 41 is in the second position when the lifting platform 22 is raised and lowered, without affecting the raising and lowering of the lifting platform 22, and is in the first position when the target U-shaped structure 101 moves, pressing down the target U-shaped structure 102 so that the canvas below the target U-shaped structure 101 will not move.

[0073] In this embodiment, the clamping plate 41 is a flat plate structure. A U-shaped structure is spaced between the quasi-target U-shaped structure 102 and the target U-shaped structure 101. This improves clamping efficiency.

[0074] In other examples, the clamping component 4 may also be other structures, such as ropes, which are tied to the canvas below the target U-shaped structure 101, so that the canvas below the target U-shaped structure 101 remains stationary.

[0075] Figure 5 yes Figure 2 Enlarged view of point A in the image, combined with Figure 5 The drive unit 42 includes a rotary drive motor 422 and a transmission gear set 423. The rotary drive motor 422 is connected to the outer wall of the canvas storage box 1, and the transmission gear set 423 is connected to the output shaft of the rotary drive motor 422. The output gear shaft of the transmission gear set 423 is connected to the pressure plate 41. The output gear shaft of the transmission gear set 423 is parallel to the output shaft of the rotary drive motor 422, and the axial direction of the output gear shaft is the same as the height direction of the canvas storage box 1.

[0076] In the above implementation, the rotary drive motor 422 serves as a power source to drive the transmission gear set 423 to rotate. The transmission gear set 423 transmits the power from the rotary drive motor 422 to the pressure plate 41, thereby driving the pressure plate 41 to rotate.

[0077] In other words, when the pressure plate 41 needs to switch positions, the rotation drive motor 422 is started to rotate. After the rotation drive motor 422 rotates, it can drive the transmission gear set 423 to rotate. After the transmission gear set 423 rotates, it can drive the pressure plate 41 to rotate, thereby switching between the first position and the second position.

[0078] In this embodiment, the transmission gear set 423 includes a first gear 4231, a second gear 4232, and a gear shaft 4233. The first gear 4231 is sleeved on the output shaft of the rotary drive motor 422. The second gear 4232 is located on one side of the first gear 4231 and meshes with the first gear 4231. One end of the gear shaft 4233 is inserted into the second gear 4232, and the other end of the gear shaft 4233 is connected to the pressure plate 41. Thus, after the rotary drive motor 422 is started, the first gear 4231 can rotate synchronously with the output shaft of the rotary drive motor 422, and the second gear 4232 can rotate under the drive of the first gear 4231. After the second gear 4232 rotates, it can drive the pressure plate 41 to rotate via the gear shaft 4233.

[0079] In this embodiment, to facilitate the installation of the clamping assembly 4, the canvas storage box 1 further includes a fixing plate 14 and two bearing seats 15. The fixing plate 14 is welded to one of the side plates 12. The fixing plate 14 is arranged parallel to the clamping plate 41. The two bearing seats 15 are connected to the surface of the fixing plate 14 facing the clamping plate 41. Each of the two bearing seats 15 contains a bearing.

[0080] The rotary drive motor 422 is fixed in the fixed plate 14, and one end of the output shaft of the rotary drive motor 422 passes through the fixed plate 14 and a bearing in one of the bearing seats 15. A bushing 4221 is provided on the outside of one end of the output shaft of the rotary drive motor 422, and the bushing 4221 is externally threaded to the cover plate 4222.

[0081] One end of the gear shaft 4233 is connected to a bearing in another bearing housing 15, and the other end of the gear shaft 4233 is provided with a flange that fits against the second gear 4232 and is connected to the clamping plate 41. This allows the gear shaft 4233 to be stably installed outside the canvas storage box 1.

[0082] See you again Figure 3 Optionally, there are two clamping components 4, which are located on opposite sides of the canvas 100 along a direction perpendicular to the opening.

[0083] In the above implementation, two clamping components 4 are set up to guide and push the opposite sides of the target U-shaped structure 101, thereby improving the efficiency of the canvas's unfolding and retraction.

[0084] In other examples, instead of two clamping components 4, there may be only one clamping component 4. However, in the direction perpendicular to the length of the translation drive rod 312, the length of the clamping plate 41 in the clamping component 4 shall not be less than half the width of each U-shaped structure. For example, the length of the clamping plate 41 shall be 2 / 3 of the width of the U-shaped structure.

[0085] In other words, the clamping plate 41 can be as long as possible, so as to extend to the opposite sides of the U-shaped structure, without being able to rotate flexibly and without interfering with other structures. In this way, the canvas below the target U-shaped structure 101 can be kept stationary in the canvas storage box 1 without being moved by the clamping plate 41.

[0086] The following is combined with Figure 6 Here is a brief introduction to the working process of the automatic canvas take-up and take-down system provided in this embodiment:

[0087] See Figure 6 When the canvas is unfolded, the guide 33 is located at the rightmost end of the opening 10 (that is... Figure 6 (The rightmost end of the opening 10). Then, control the lifting platform 22 to move upward, so that the U-shaped structure at the top inside the canvas storage box 1 is in the opening 10. External force pulls the canvas, so that one end of the canvas extends out of the canvas storage box 1, and the U-shaped structure at the top inside the canvas storage box 1 becomes the target U-shaped structure. Control the guide 33 to move to the left and fit against the end of the target U-shaped structure away from its own opening.

[0088] External force pulls the target U-shaped structure 101 (that is... Figure 6 The topmost layer of the U-shaped structure (that is) Figure 6 The top layer of canvas in the target U-shaped structure 101 is moved outwards and out of the opening 10. At the same time, since the guide 33 is attached to the target U-shaped structure 101, the guide 33 moves synchronously with the top layer of canvas in the target U-shaped structure 101.

[0089] At this time, the control drive motor 422 is turned so that the clamping plate 41 is in the first position, located in the target U-shaped structure 102, and is in contact with the end of the target U-shaped structure 102 away from its own opening (that is, the clamping plate 41 is at the leftmost end of the third U-shaped structure from the top in Figure 6). The clamping plate 41 presses the canvas below the target U-shaped structure 101 and keeps it fixed. After the top layer of canvas in the target U-shaped structure 101 moves out of the opening 10, the guide 33 also moves from the leftmost end to the rightmost end.

[0090] Next, the rotation drive motor 422 is controlled to switch the clamping plate 41 from the first position to the second position. Then, the lifting platform 22 is controlled to move upward by the distance of a U-shaped structure, so that the original quasi-target U-shaped structure 102 becomes the new target U-shaped structure 101.

[0091] Then, the rotation drive motor 422 is controlled to drive the clamping plate 41 to switch from the second position to the first position, placing it in the new target U-shaped structure 102. Then, the translation drive 31 is controlled to reset the guide 33, moving it from the rightmost end to the leftmost end of the new target U-shaped structure 101. Repeating the above steps can complete the automatic release of the canvas.

[0092] The automatic retraction process of the canvas is exactly the reverse of the process described above.

[0093] When the canvas is retracted, the guide 33 is located at the rightmost end of the opening 10 (that is... Figure 6 (The rightmost end of the opening 10). Control the lifting platform 22 to rise, so that the lifting platform 22 is located in the opening 10. External force pulls the canvas, so that the canvas forms the target U-shaped structure 101 in the opening 10.

[0094] The control guide 33 moves to the left, and the guide 33 is located inside the target U-shaped structure 101 and fits against the end of the target U-shaped structure 101 away from the opening.

[0095] The control clamping plate 41 is in the first position, that is, it is located in the quasi-target U-shaped structure 102 and is attached to the end of the quasi-target U-shaped structure 102 away from the opening.

[0096] An external force pulls the canvas, causing the top layer of canvas in the target U-shaped structure 101 to be in a horizontally extended state. Driven by the translation drive motor 311, the control guide 33 moves from the rightmost end of the canvas storage box 1 to the left along the length of the translation drive rod 312, thus extending the target U-shaped structure 101 (i.e., the top layer of canvas in the target U-shaped structure 101) into a horizontally extended state. Figure 6 The topmost layer of the U-shaped structure at the very top (that is...) Figure 6 The topmost canvas moves to the left in sync with the guide 33, lays flat and occupies the opening 10, so that the length of the target U-shaped structure 101 increases to the length of the U-shaped structure stored in the canvas storage box 1.

[0097] The control guide 33 moves from the leftmost end to the rightmost end.

[0098] The control clamping plate 41 is switched from the first position to the second position under the drive of the rotation drive motor 422. The control lift platform 22 is also moved downward by the distance of a U-shaped structure, so that the original target U-shaped structure 101 becomes the quasi-target U-shaped structure 102.

[0099] Then, the drive motor 422 is controlled to switch the clamping plate 41 from the second position to the first position, positioning it within the new target U-shaped structure 102. Next, the canvas outside the canvas storage box 1 is rolled into the new target U-shaped structure, and the guide 33 is positioned within the new target U-shaped structure 101, causing the rightmost end of the guide 33 to move to the leftmost end within the new target U-shaped structure 101. Repeating these steps completes the automatic retraction of the canvas.

[0100] On the other hand, embodiments of this disclosure also provide an automatic canvas deployment and retraction method, such as... Figure 7 As shown, the automatic canvas take-up and take-down method is implemented through the automatic canvas take-up and take-down system described above. The automatic canvas take-up and take-down method includes:

[0101] S701: The target U-shaped structure is placed in an opening by means of the lifting component in the automatic canvas retraction system.

[0102] S702: Place the guide component in the automatic canvas take-up and take-down system inside the target U-shaped structure, and make the guide component fit against the end of the target U-shaped structure away from its own opening.

[0103] S703: The control guide moves synchronously back and forth with the top layer of canvas in the target U-shaped structure along the opening direction.

[0104] The above-described automatic canvas take-up and take-down methods have the same beneficial effects as the automatic canvas take-up and take-down system, and will not be elaborated further here.

[0105] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
