Description

Technical Field

[0001] This utility model relates to the field of film processing equipment, and in particular to a fully automatic film winding machine. Background Technology

[0002] As a crucial medium for image recording, film's core imaging layer is the emulsion layer. This layer contains photosensitive silver halide particles that are extremely sensitive to light. Exposure to uncontrolled light or physical damage during processing will directly render the film unusable, causing irreversible economic losses. Therefore, strict control of the operating environment and precision is essential throughout the entire film processing process. During processing, storage, and transportation, to prevent wear, moisture absorption, adhesion, or accidental exposure of the emulsion layer, film is typically wound onto a reel together with oiled paper (a special release paper with moisture-proof, scratch-resistant, and light-blocking properties), forming an alternating "film-oiled paper" roll structure to create a double protective barrier.

[0003] In existing technologies, the winding of film and parchment paper mostly relies on manual operation, which has the following drawbacks: 1. When winding manually, the operator needs to manually and synchronously pull the film and the oil paper in a semi-dark room environment and wind them around the film roll one turn at a time. During this process, the operator's hand shaking and uncoordinated movements can easily cause the film and oil paper to shift, causing some of the film to be exposed. If the ambient light is not properly controlled, the exposed film is very likely to be exposed and wasted. 2. Manual operation is labor-intensive and inefficient, and uneven tension can easily lead to loose winding, which can damage the emulsion layer due to interlayer friction during subsequent storage or transportation.

[0030] like Figure 1-9 As shown, the present invention provides a fully automatic film winding machine, which includes a frame 1, and a film conveyor 2, an oil paper conveyor 3, a film reel conveyor 4, a handling robot 5, and a winding mechanism 6 are installed on the front side of the frame 1. The oil paper conveyor 3 is equipped with an oil paper roll 7. After the oil paper roll 7 is pulled out, it is horizontally inserted into the winding mechanism 6. The film conveyor 2 is equipped with a film roll 8. After the film roll 8 is pulled out, it is inclinedly inserted into the winding mechanism 6. The film spool conveyor 4 is located on the left side of the winding mechanism 6. Multiple film spools 9 are connected and driven inside the film spool conveyor 4. The handling robot 5 clamps a single film spool 9 inside the film spool conveyor 4 and transports it to the winding mechanism 6. The winding mechanism 6 drives the film shaft 9 to rotate. After the film roll 8 is pulled out, it is attached to the oil paper roll 7, and the film roll 8 and the oil paper roll 7 are wound together on the film shaft 9. The principle is as follows: A fully automated winding infrastructure is built, replacing traditional manual winding operations through the collaboration of film conveyor 2, oil paper conveyor 3, film reel conveyor 4, handling robot 5, and winding mechanism 6; the layout of tilted film insertion and horizontal oil paper insertion is clearly defined to ensure precise fit between the two within the winding mechanism 6; the handling robot 5 automatically feeds the film reel 9, and the winding mechanism 6 drives its rotation, achieving fully automated assembly between the reel, film, and oil paper, fundamentally avoiding film layering misalignment and exposure risks caused by manual operation, while improving winding efficiency; the equipment needs to be placed in a dark environment for production and processing to effectively avoid the risk of film exposure and waste.

[0031] Furthermore: The oil paper conveyor 3 is equipped with a plurality of first guide rollers 31 and a plurality of first tension rollers 32. The first guide rollers 31 are rotatably mounted on the front side of the frame 1. The rear side of the first tension rollers 32 is fixedly mounted with a first lifting block 33. The front side of the frame 1 is fixedly mounted with a first lifting slide rail 34. The first lifting block 33 is slidably mounted on the first lifting slide rail 34. The oil paper roll 7 is horizontally conveyed through the plurality of first guide rollers 31 and the plurality of first tension rollers 32 and inserted into the film shaft 9 in the winding mechanism 6. Furthermore: The film conveyor 2 is equipped with a plurality of second guide rollers 21 and a plurality of second tension rollers 22. The second guide rollers 21 are rotatably mounted on the front side of the frame 1. The rear side of the second tension rollers 22 is fixedly mounted with a second lifting block 23. The front side of the frame 1 is fixedly mounted with a second lifting slide rail 24. The second lifting block 23 is slidably mounted on the second lifting slide rail 24. The film roll 8 is inclinedly conveyed through the plurality of second guide rollers 21 and the plurality of second tension rollers 22 and inserted into the film shaft 9 in the winding mechanism 6.

[0032] Furthermore: The oil paper conveyor 3 is equipped with a stamping die 10, through which the oil paper roll 7 is stamped and cut; the stamping die 10 performs real-time stamping and cutting of the oil paper roll 7, and the cutting size can be adjusted according to the film winding requirements, eliminating the need for manual pre-processing of the oil paper, avoiding dimensional errors caused by manual cutting, ensuring that the oil paper and film are perfectly matched, improving the protective consistency of the wound product, and reducing the waste of oil paper materials.

[0033] Furthermore: The film spool conveyor 4 is equipped with a steering mechanism 11, which drives a single film spool 9 to rotate back to center. The steering mechanism 11 drives a single film spool to rotate back to center, which solves the problem of directional deviation caused by placement or collision during the conveying process, avoids winding misalignment caused by incorrect film spool direction, ensures accurate docking between the winding mechanism 6 and the film spool, and improves the overall operational stability of the equipment.

[0034] Furthermore, the steering mechanism 11 includes a vision inspection mechanism 111, a rotary cylinder 112, and an arc-shaped centering plate 113. The vision inspection mechanism 111 is fixedly installed on the upper left side of the film spool conveyor 4. The vision inspection mechanism 111 performs reverse inspection on the film spool 9 conveyed in the film spool conveyor 4. The rotary cylinder 112 is fixedly installed on the front side of the film spool conveyor 4. The arc-shaped centering plate 113 is fitted with a clearance fit in the film spool conveyor 4. The rotary cylinder 112 drives the arc-shaped centering plate 113 to rotate, and the arc-shaped centering plate 113 drives a single film spool 9 to rotate back to center. The vision inspection mechanism 111 can accurately identify the direction of the film spool, replacing manual visual judgment and reducing inspection errors. The rotary cylinder 112 drives the arc-shaped centering plate 113 to smoothly drive the film spool to rotate through the arc-shaped contact surface, avoiding physical damage to the film spool, while ensuring that the centering action is fast and accurate, further improving the consistency of film spool conveying and ensuring the stability of subsequent winding processes.

[0035] Furthermore, the vision inspection mechanism 111 adopts an industrial camera; the industrial camera has the characteristics of high resolution and high response speed, and can accurately capture directional features during the rapid transport of the film shaft. Compared with other detection methods (such as infrared detection), it can more clearly identify the details of the film shaft, reduce the misjudgment rate, and ensure that the steering mechanism 11 only adjusts the film shaft with the wrong direction, thereby improving the overall operating efficiency of the equipment.

[0036] Furthermore: A film spool feeding mechanism 12 is fixedly installed on the left side of the frame 1. The film spool feeding mechanism 12 includes a hopper 121, a lifting cylinder 122, and several lifting edges 123. Film spools 9 are placed in batches in the hopper 121. The bottom side of the hopper 121 is inclined to the right. Several fixed edges 124 are fixedly installed on the right side of the hopper 121. The fixed edges 124 are parallel to each other and separated. The lifting edges 123 are staggered between two fixed edges 124. The lifting cylinder 122 drives the lifting edges 123 to move up and down. The hopper 121 can store film spools 9 in batches. The inclined bottom surface facilitates the natural sliding of the film spools 9. The lifting edges 123 and fixed edges 124 are raised and lowered alternately to realize the orderly and gradual conveying of film spools and avoid the accumulation and blockage of film spools. There is no need to manually place film spools one by one, which reduces the labor intensity of operators and ensures the matching of the feeding rhythm with the subsequent conveying and winding processes, thereby improving the overall production efficiency.

[0037] Furthermore, the top surfaces of both the lifting edge 123 and the fixed edge 124 are inclined to the right; gravity assists the movement of the film shaft 9, reducing the frictional resistance between the film shaft 9 and the lifting edge 123 and the fixed edge 124, ensuring that the film shaft 9 slides smoothly during lifting and conveying, avoiding film shaft retention and jamming caused by flat contact surfaces, and further improving the stability and conveying efficiency of the film shaft 9 feeding mechanism.

[0038] Furthermore: A belt conveyor 13 is provided between the hopper 121 and the film shaft conveyor 4. The film shaft feeding mechanism 12 drives the film shafts 9 to be conveyed into the belt conveyor 13. A push cylinder 14 is fixedly installed on the left side of the front end of the belt conveyor 13. The push cylinder 14 pushes the film shafts 9 one by one into the film shaft conveyor 4. The belt conveyor 13 receives the film shafts 9 output from the hopper 121 and avoids collision damage to the film shafts 9 through smooth conveying. The push cylinder 14 pushes the film shafts into the film shaft conveyor 4 one by one, replacing manual sorting and pushing, ensuring that the film shafts 9 are arranged individually and orderly during the conveying process, avoiding overlapping or misalignment of the film shafts 9, providing a guarantee for the accurate detection and return of the subsequent steering mechanism 11, and further improving the automation level of the feeding process.

[0039] Furthermore, a clamping mechanism 15 is provided on the left side of the winding mechanism 6. The clamping mechanism 15 includes a clamping cylinder 151, a clamping frame 152, and two clamping wheels 153. The clamping cylinder 151 is fixedly installed on the front side of the frame 1. The clamping cylinder 151 drives the clamping frame 152 to move left and right. The two clamping wheels 153 are rotatably installed in the clamping frame 152, and the two clamping wheels 153 press the film shaft 9 into the winding mechanism 6. The clamping cylinder 151 drives the clamping frame 152 to move, so that the two clamping wheels 153 tightly press the film shaft 9 onto the winding mechanism 6, ensuring that the film shaft 9 does not wobble during the rotation and winding process. At the same time, the rotation of the clamping wheels 153 is coordinated with the rotation of the film shaft to avoid friction damage to the film shaft 9, effectively solving the problem of loose winding caused by uneven tension in manual winding, and reducing the risk of wear of the emulsion layer during subsequent storage and transportation.

[0040] Furthermore: A discharge plate 16 is provided below the clamping frame 152. The discharge plate 16 is tilted to the left. The clamping cylinder 151 drives the clamping frame 152 to move closer to or away from the discharge plate 16. A discharge box 17 is fixedly installed on the frame 1. The discharge box 17 is located below the discharge plate 16. Film shafts 9 in the opposite direction in the film shaft conveyor 4 pass through the gap between the clamping frame 152 and the discharge plate 16 and fall into the discharge box 17 for recycling. Unqualified film shafts 9 in the opposite direction can fall into the discharge box 17 along the inclined discharge plate 16 through the gap between the clamping frame 152 and the discharge plate 16, without the need for manual screening and recycling. This avoids material waste caused by unqualified film shafts 9 entering the winding process (such as the ineffective consumption of film and oil paper, and avoids the situation where film and oil paper cannot be inserted into the film shaft 9 for winding), while reducing the time cost of manual sorting and improving the economy and automation of equipment operation.

[0041] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
