Description

Technical Field

[0001] This invention relates to the field of flexible sheet processing equipment, and more particularly to a flexible thin sheet rolling mechanism and a rolling machine comprising the same. Background Technology

[0002] In automated production, incoming materials are typically sheets for convenient transportation and loading. However, in actual use, to adapt to the operating environment, these sheets usually need to be rolled into cylindrical rolls before being installed onto various parts of the product. For example, in oil valves, to improve their wear resistance, a Teflon anti-slip layer is usually added. The Teflon anti-slip layer arrives as a sheet, but to fit the oil valve, it needs to be rolled into a cylindrical shape and placed inside. Due to the complexity of the rolling process, current sheet rolling is usually done manually. However, manual rolling leads to slow work efficiency, high deviations, increased costs, and a significant reduction in product yield. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide a flexible thin sheet material winding mechanism that utilizes the bending and stretching characteristics of thin sheet materials to cleverly realize the automatic winding and installation of thin sheet parts through contouring.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a flexible sheet-like material rolling mechanism, including a vertical plate, on which a rolling device, a pushing device, and a feeding device are provided. The rolling device includes a film rolling seat fixed on the vertical plate. A film rolling cavity with a circular cross-section is vertically arranged inside the film rolling seat. A feeding channel tangential to and communicating with the film rolling cavity is also provided on the film rolling seat. The pushing device pushes the sheet into the film rolling seat from the feeding channel. The sheet moves within the film rolling cavity and forms a roll under the limitation and guidance of the film rolling cavity.

[0005] The beneficial effects of this invention are as follows: the winding device utilizes the winding cavity within the winding seat, allowing the sheet material to move along the winding cavity under the action of the sheet material pusher. By utilizing its own bending and stretching characteristics, it abuts against the outer wall of the winding cavity, which has a circular cross-section, forming a roll material that matches the winding cavity. This cleverly achieves automatic winding and installation of thin sheet parts through contouring.

[0006] Furthermore, the film winding base includes a housing fixed to the upright plate and a guide post vertically inserted into the housing. The housing has a through hole through which the guide post passes. The fixed post is fixedly connected to the housing, and the guide post and the sidewall of the through hole define the film winding cavity. The film winding cavity, formed by the housing and the guide post, is easy to manufacture.

[0007] Furthermore, the housing includes a winding section and a guide section arranged vertically. The through hole penetrates both the winding section and the guide section. The lower end face of the guide post is flush with the lower end face of the guide section. The feeding channel is located on the winding section. The sheet material enters the winding cavity of the winding section through the feeding channel, and the winding is completed within the winding section. The completed roll of material slides out of the housing from the guide section, improving the stability of the roll material unloading.

[0008] Furthermore, the feeding device includes a feeding blade with an end that can abut against the sheet. The feeding blade is fixed to the feeding drive assembly and can enter the feeding channel and slide within the feeding channel under the action of the feeding drive assembly. The feeding drive assembly is fixed to the upright plate. The feeding blade slides under the push of the feeding drive assembly, pushing the sheet into the feeding channel and allowing the sheet to move along the winding cavity to complete the winding. When the end of the feeding blade that abuts against the sheet reaches the tangent point between the feeding channel and the winding cavity, the sheet is completely entered into the winding cavity to complete the winding.

[0009] Furthermore, a limiting block is fixed to the upright plate, and a feeding gap is left between the limiting block and the film winding seat for feeding the sheet. The pusher blade can pass through the limiting block and abut against the sheet within the feeding gap. The limiting block provides a feeding gap for the sheet, making it easy to place the sheet accurately within the feeding gap. On the other hand, it guides the pusher blade, improving the stability of its movement. At the same time, the limiting block also limits the distance the pusher blade moves toward the film winding seat, effectively protecting the pusher blade and preventing its end from hitting the film winding seat and causing damage to both the pusher blade and the film winding seat.

[0010] Furthermore, the fixing plate is also fixed with two guide strips at the feeding spacing. The guide strips are arranged parallel to each other and extend along the sliding direction of the pusher blade. The guide strips are located at the upper and lower ends of the pusher blade and match the height of the pusher blade. Both the pusher blade and the sheet are slidably connected between the two guide strips. The guide strips limit the pusher blade and the sheet on the vertical plane, improving the stability of the pusher blade and the sheet sliding.

[0011] Furthermore, the feeding device is used to eject the roll material formed by the winding device from the winding device. The feeding device includes a feeding blade and a feeding drive assembly. The feeding drive assembly is fixed on the vertical plate and is used to drive the feeding blade into the winding cavity. The feeding blade moves up and down along the axial direction of the winding cavity, and the feeding blade can abut against the upper end face of the formed roll material. When the feeding blade moves downward, it can push the roll material to slide out of the winding device.

[0012] Furthermore, the unloading blade is cylindrical, and it has a strip-shaped clearance notch along its axial direction, facing the tangent point between the feed channel and the film winding cavity. The unloading blade and the feed blade move in perpendicular directions. The unloading blade is C-shaped, and there is a gap between the two ends of the unloading blade in the circumferential direction and the feed channel. The clearance notch prevents the unloading blade from colliding with the loading blade during movement, ensuring that while the unloading blade is unloading, the loading blade can slide within the feed channel, exit the feed channel, and move back to its initial position to prepare for the next feed, greatly improving processing efficiency.

[0013] Furthermore, a detection channel is provided through the guide post located within the roll section, the detection channel being perpendicular to the axis of the guide post and parallel to the feed channel. A detection sensor corresponding to the detection channel is provided on the housing. The detection sensor detects the presence or absence of sheet material within the roll cavity. When the sheet material enters the roll cavity and completes the roll winding, the detection sensor detects that the roll winding is complete and can trigger the unloading device to push the roll material out.

[0014] The present invention also provides a winding machine that utilizes the bending and stretching characteristics of thin sheet materials to achieve automatic winding and installation of thin sheet parts by cleverly using contouring.

[0015] The technical solution adopted in this invention is a winding machine, including the aforementioned winding mechanism, and also a worktable. The worktable is equipped with a vacuum feeding mechanism, a processing mechanism, and a cross slide. A vertical plate is fixed on the cross slide, and the vertical plate can move back and forth between the vacuum feeding mechanism and the processing mechanism under the drive of the cross slide. Furthermore, the cross slide can drive the vertical plate to move up and down, moving it closer to or further away from the vacuum feeding mechanism and the processing mechanism in the vertical direction. The winding machine can achieve automatic feeding of sheet materials, cleverly utilizing contouring to achieve automatic winding of thin sheet parts, with a high degree of automation and significant cost savings.

Detailed Implementation

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0032] Example

[0033] See appendix Figure 1As shown, the flexible sheet-like material rolling mechanism of the present invention includes a vertical plate 1, on which a rolling device 2, a pushing device 3, and a feeding device 4 are disposed. The pushing device 3 pushes the sheet 11 into the rolling device 2. During the process of entering the rolling device 2, the sheet 11 is rolled up by mechanical physical conforming. The feeding device 4 pushes the rolled material formed by the rolling device 2 out of the rolling device 2. The sheet 11 is a flexible material with a certain degree of plasticity. When an external force is applied to the sheet 11, if the external force exceeds a certain value, the sheet 11 will undergo irreversible deformation, such as thin sheets made of Teflon or steel. See the attached diagram for the rolled material. Figure 12 As shown, it is a cylindrical structure.

[0034] See attached document Figure 2-3 As shown, the film winding device 2 includes a film winding base 21 fixed on the upright plate 1. A film winding cavity 22 with a circular cross-section is vertically arranged inside the film winding base 21. A feeding channel 23 is also provided on the film winding base 21, tangential to and communicating with the film winding cavity 22. One end of the feeding channel 23 communicates with the film winding cavity 22, and the other end passes through the film winding base 21 to form a feeding port. The sheet 11 enters through the feeding channel 23 under the push of the pushing device 3. Under the constraint and guidance of the film winding cavity 22, it forms a roll. The process of the sheet 11 turning into a roll is described in the appendix. Figure 2 As shown by the hollow arrow in the diagram. The width of the film winding cavity 22 is the same as the width of the feeding channel 23 and matches the thickness of the sheet 11. That is, the width of the film winding cavity 22 is the same as or slightly larger than the thickness of the sheet 11, ensuring that the sheet 11 fits into the film winding cavity 22 and the feeding channel 23 without wrinkles, thus improving the winding effect.

[0035] See attached document Figure 4 As shown, the feeding device 3 includes a feeding blade 31 that can slide along the feeding channel 23. The feeding blade 31 is fixed on the feeding drive assembly 32 and can enter the feeding channel 23 and slide within it under the action of the feeding drive assembly 32. The feeding blade 31 has a cuboid structure and its thickness is less than that of the feeding channel 23. The end of the feeding blade 31 can abut against the sheet 11 and push the sheet 11 into the feeding channel 23 first, and then continuously into the film winding cavity 22. When the feeding blade 31 moves to the tangent point between the feeding channel 23 and the film winding cavity 22, the sheet 11 is completely entered into the film winding cavity 22, and the film is wound around the film winding cavity 22 to complete the winding.

[0036] The pusher drive assembly 32 is fixed on the upright plate 1. The pusher drive assembly 32 includes a pusher drive component and a slider 321 that slides along the feeding direction of the feeding channel 23 under the action of the pusher drive component. The end of the pusher blade 31 is fixed on the slider 321. In order to save space, the pusher drive component is fixed on the opposite surface of the upright plate 1 to the surface on which the film roll holder 21 is fixed. That is, the film roll holder 21 is fixed on the front end surface of the upright plate 1, and the pusher drive component is fixed on the rear end surface of the upright plate 1. The slider 321 can extend to the front end surface of the upright plate 1.

[0037] See attached document Figure 1 and 2 As shown, a limiting block 5 is fixed on the upright plate 1 between the film roll holder 21 and the slider 321. A feeding gap is left between the limiting block 5 and the film roll holder 21 for feeding the sheet 11. The sheet 11 is first placed at the feeding gap, and can be adsorbed by the vacuum suction cup 82 before being placed on the feeding gap. Then, it is pushed into the feeding channel 23 by the pusher blade 31. The limiting block 5 is provided with a through hole for the pusher blade 31 to pass through. The feeding gap matches the size of the sheet 11 and can be flexibly adjusted according to the size of the sheet 11. The limiting block 5 also limits the movement distance of the pusher blade 31. When the slider 321 abuts against the limiting block 5, it stops pushing the pusher blade 31 to continue moving. At this time, the end of the pusher blade 31 just reaches the tangential position between the feeding channel 23 and the film roll cavity 22. Simultaneously, the limiting block 5 also serves as a guide, guiding the pusher blade 31.

[0038] To improve the stability of the pusher and the roll material during movement, two guide strips 51 are fixed to the fixing plate at the feeding spacing. The two guide strips 51 are parallel and extend along the sliding direction of the pusher blade 31. The guide strips 51 are located at the upper and lower ends of the pusher blade 31 and match its height; that is, the distance between the two guide strips 51 is the same as or slightly greater than the height of the pusher blade 31, while the height of the sheet 11 is the same as the height of the pusher blade 31. The pusher blade 31 and the sheet 11 slide sequentially between the two guide strips 51 and insert into the feeding channel 23, reducing the vertical offset of the pusher blade 31 and the sheet 11 and improving the stability of their movement.

[0039] See appendix Figure 5 and 6As shown, the roll holder includes a housing 211 fixed to the upright plate 1 and a guide post 212 vertically inserted into the housing 211. A through hole 2111 is provided on the housing 211 for the guide post 212 to pass through. The guide post is fixedly connected to the housing 211, and a roll-up cavity 22 is defined between the guide post 212 and the side wall of the through hole 2111. The housing 211 includes a roll-up section 211a and a guide section 211b arranged vertically. The through hole 2111 penetrates both the roll-up section 211a and the guide section 211b. A feeding channel is provided on the roll-up section 211a. The sheet 11 enters the roll-up cavity 22 located in the roll-up section 211a through the feeding channel 23, completing the roll-up. After the roll-up is completed, it slides out along the roll-up cavity 22 of the guide section 211b under the push of the unloading device 4, improving the stability of the unloading. Simultaneously, during the unloading process, the pushing device 3 can continue to push the sheet, improving work efficiency. The lower end face of the guide post 212 is flush with the lower end face of the guide part 211b, so that the rolled material formed by the roll can be stably slid out of the housing 211 under the guidance of the guide post 212.

[0040] See appendix Figure 7 As shown, in order to facilitate the fixing of the guide post 212, an integrally formed upper cover 2122 is fixed to the upper end of the guide post 212, and the upper cover 2122 is fixed to the upper end face of the housing 211 by bolts.

[0041] A detection channel 2121, penetrating only the guide post 212, is provided on the guide post 212. The detection channel 2121 is perpendicular to the axis of the guide post 212, and its axis is parallel to the feed channel 23. The detection channel 2121 is located within the winding section 211a. A detection sensor 6, corresponding to the detection channel 2121, is provided on the housing 211. The detection sensor 6 is located outside the winding cavity 22 and can be an infrared detection sensor 6, used to detect the presence or absence of sheet 11 within the winding cavity 22. The detection sensor 6 emits infrared light into the detection channel 2121. When the sheet 11 has not entered the winding cavity 22, the detection sensor 6 can receive the emitted infrared light. When the sheet 11 has entered the winding cavity 22 and completed winding, the detection sensor 6 can no longer receive the emitted infrared light, indicating that winding is complete, and the unloading device 4 can be activated to push the roll out.

[0042] See appendix Figure 4 As shown, the feeding device 4 includes a feeding blade 41 and a feeding drive assembly 42. The feeding drive assembly 42 is used to drive the feeding blade 41 into the film winding cavity 22 and move it up and down along the axial direction of the film winding cavity 22. After the feeding blade 41 enters the film winding cavity 22, it can abut against the upper end face of the formed roll material, push the roll material down, and push the roll material out of the feeding device 2.

[0043] In one embodiment, see Appendix Figure 8As shown, the unloading blade 41 is C-shaped, meaning it is cylindrical and has a axially oriented clearance notch 411. The clearance notch 411 faces the tangent point between the feed channel 23 and the film winding cavity 22, allowing space for the back-and-forth movement of the loading blade. The movement directions of the unloading blade 41 and the feed blade are perpendicular. A gap is maintained between the two circumferential ends of the unloading blade 41 and the feed channel 23. The clearance notch 411 prevents the unloading blade 41 from colliding with the loading blade during movement, ensuring that while the unloading blade is unloading, the loading blade can slide within the feed channel 23, exit the feed channel 23, and return to its initial position to prepare for the next feed, greatly improving processing efficiency.

[0044] See appendix Figure 7 As shown, the upper cover 2122 has an infeed hole 2122a that matches the cross-section of the unloading knife 41. The infeed hole 2122a has a C-shaped structure, which guides the insertion of the unloading knife 41 and improves stability to prevent the unloading knife 41 from rotating.

[0045] The unloading drive assembly 42 includes an unloading drive component and a lifting plate 421 that moves axially along the film winding cavity 22 under the action of the unloading drive component. The end of the unloading knife 41 is fixed on the lifting plate 421. The lifting plate 421 serves to fix the unloading knife 41 in one direction and to limit the movement distance of the unloading knife 41 in another direction. When the lifting plate 421 abuts against the upper cover 2122, the unloading drive component no longer drives the lifting plate 421 to move. The unloading drive component is a cylinder fixed on the vertical plate 1, and the piston rod of the cylinder is fixedly connected to the lifting plate 421.

[0046] During the winding process, the sheet 11 is first placed at the feeding gap. Then, the pushing drive assembly 32 drives the pushing knife 31 to move. After the end of the pushing knife 31 abuts against the end of the sheet 11, it pushes the sheet 11 into the feeding channel 23. The pushing knife 31 continues to push the sheet. After the end of the sheet 11 reaches the tangent between the feeding channel 23 and the winding cavity 22, it enters the winding cavity 22 along the intersection of the feeding channel 23 and the winding cavity 22. Under the push of the pushing knife 31, it moves along the winding cavity 22 to form a roll. Due to the friction between the sheet 11 and the winding cavity 22, the formed roll does not fall down along the winding cavity 22. At this time, the detection sensor 6 detects that the winding is complete, and the unloading drive assembly drives the unloading knife 41 to move down, pushing the roll in the winding cavity 22 out of the winding cavity 22 axially.

[0047] See appendix Figure 9As shown, in another embodiment, a winding machine is also disclosed. The winding machine includes a worktable 7, on which a vacuum feeding mechanism 8, a processing mechanism 9, and a cross slide 10 are provided. A vertical plate 1 is fixed on the cross slide 10. The vertical plate 1 can move back and forth between the vacuum feeding mechanism 8 and the processing mechanism 9 under the drive of the cross slide 10. The cross slide can drive the vertical plate 1 to move up and down to move closer to or further away from the vacuum feeding mechanism 8 and the processing mechanism 9 in the vertical direction.

[0048] See appendix Figure 10 As shown, the cross slide 10 includes a first upright 101 fixed on the worktable 7. A first horizontal slide plate 102 is slidably connected to the first upright 101. The first horizontal slide plate 102 moves back and forth between the vacuum feeding mechanism 8 and the processing mechanism 9 under the push of a first horizontal cylinder 103. The first horizontal cylinder 103 is fixed on the first upright 101. The upright plate 1 can move up and down along the first horizontal slide plate 102. A first vertical cylinder 104 is fixed on the first horizontal slide plate 102 to push the upright plate 1 up and down. The first horizontal cylinder 103 and the first vertical cylinder 104 cooperate to drive the winding mechanism to reach the working range of the vacuum feeding mechanism 8 and the processing mechanism 9.

[0049] In another embodiment, the upright plate 1 can also be fixed to the robotic arm directly, without the need for the cross slide 10, as long as the robotic arm can drive the upright plate 1 to move.

[0050] The vacuum suction feeding mechanism 8 is used to pick up the sheets 11 one by one and transport them to the winding mechanism. See Appendix Figure 11 As shown, the vacuum feeding mechanism 8 includes a moving device 81 and a vacuum suction cup 82 fixed on the moving device 81. The moving device 81 drives the vacuum suction cup 82 to the position where the sheet 11 is stored. The vacuum suction cup 82 picks up a sheet 11, and then the vacuum suction cup 82 moves to the feeding gap of the winding mechanism. The vacuum suction cup 82 fixes the sheet 11 at the feeding gap until the pusher blade 31 pushes the sheet 11 into the feeding channel 23. Then the vacuum suction cup 82 resets and picks up the next sheet 11.

[0051] The moving device 81 can drive the vacuum suction cup 82 to rise, rotate, and move closer to or away from the cross slide table 10. In one embodiment, the moving device 81 includes a second upright 811 fixed on the worktable 7, and a second horizontal slide plate 812 slidably connected to the second upright 811. The second horizontal slide plate 812 is perpendicular to the moving direction of the first horizontal slide plate 102. The second horizontal slide plate 812 moves closer to or away from the cross slide table 10 under the push of a second horizontal cylinder, which is fixed to the second upright 811. A rotary cylinder 813 is fixed to the second horizontal slide plate 812, and the rotary cylinder 813 can drive a rotating plate to rotate. A second vertical cylinder 814 is fixed to the rotating plate, and the vacuum suction cup 82 is fixed to the telescopic rod of the second vertical cylinder 814.

[0052] In another embodiment, the moving device 81 can also be a robotic arm fixed to the worktable 7, with the vacuum suction cup 82 fixed to the output end of the robotic arm. The moving device 81 is only required to move the vacuum suction cup 82, allowing it to pick up and move the sheet 11; its specific type is not limited. The moving device 81 moves the suction cup holding the sheet 11 to the feeding gap, and then the sheet 11 is pushed into the feeding channel 23 by the pusher blade 31. At this time, the suction cup can be reset under the drive of the moving device 81 to pick up the next sheet 11.

[0053] The processing mechanism 9 is used for conveying the workpiece, including a support plate on which the workpiece is placed. When the workpiece arrives below the winding mechanism, the winding mechanism moves to the film holder 21 and abuts against the workpiece. At this time, the unloading drive drives the unloading knife 41 to move down, pushing the roll material out of the film holder 21 and into the workpiece, thus completing the fixing of the roll material and the workpiece.

Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention.
