Description

Technical Field

[0001] This application relates to the field of packaging film removal equipment technology, and in particular to a film removal device and a film removal system. Background Technology

[0002] For ease of transport and storage, a stack typically consists of multiple boxes piled together, usually wrapped in packaging film to prevent them from falling apart. In this case, when destacking, the packaging film must be removed first, and then the boxes on the stack can be disassembled.

[0003] Previously, packaging film was usually wrapped around the entire stack of goods, that is, wrapped around the top, bottom, left, right and front of the stack. However, recently, non-wrap packaging film has emerged, that is, the packaging film does not wrap the entire stack, but only wraps the part between the top and bottom ends of the stack.

[0004] For non-integral wrapping film, the height of the film may vary for different products, or even for the same product. Therefore, it is a challenge to easily remove non-integral wrapping film at different heights. Summary of the Invention

[0024] In some embodiments, the film removal mechanism engages with the packaging film after the film breaking device breaks the packaging film and separates the packaging film from the stack to remove the packaging film broken by the film breaking device from the stack. The film removal equipment also includes a film winding mechanism, which is disposed on the frame and is used to wind the packaging film removed from the stack by the film removal device into a film roll.

[0025] In some embodiments, the film rolling mechanism includes a winding mechanism rotatably mounted on a frame to wind packaging film removed from the stack by the film removal device into a film roll during rotation.

[0070] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0071] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0072] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0073] In the description of this application, it should be understood that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.

[0074] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0075] Figures 1-15 The structure of the membrane removal system and membrane removal equipment in this application is illustrated by way of example.

[0076] See Figures 1-15 In this application, the film removal system 100 includes a conveying device 20 and a film removal device 10. The conveying device 20 is used to convey a stack of goods 30. A packaging film 40 is wrapped around the stack of goods 30. The film removal device 10 is used to remove the packaging film 40 from the stack of goods 30, and is located on one side of the conveying device 20 along a first direction W perpendicular to the vertical direction H, such that the stack of goods 30 on the conveying device 20 is located on one side of the film removal device 10 along the first direction W.

[0077] Based on the conveying equipment 20 and the film removal equipment 10, the film removal system 100 can realize the automatic conveying of the stack 30 and the automatic removal of the packaging film 40 on the stack 30.

[0078] Among them, see Figures 1-3 The packaging film 40 on the stack 30 is a non-integral wrapping packaging film, which does not wrap around the top and bottom ends of the stack 30, but only wraps between the top and bottom ends of the stack 30.

[0079] Due to the complexity of the product specifications, the height of different specifications of the stacks 30 is different, and the position of the packaging film 40 on the stacks 30 is also different. Moreover, the same product may be produced by multiple production lines. When different production lines produce the same product, the position of the packaging film 40 on the stacks 30 may not be the same. Therefore, the position of the non-integral packaging film is variable.

[0080] In related technologies, film removal equipment 10 can usually only remove integral packaging film. However, for the aforementioned non-integral packaging film that has recently emerged, there is no dedicated film removal equipment 10, and it is impossible to use the same film removal equipment 10 to effectively remove packaging films of different specifications and locations.

[0081] In view of the above situation, this application improves the structure of the membrane removal device 10.

[0082] See Figures 1-15 In this application, the film removal equipment 10 includes a frame 1, a height detection device 2, and a film cutting device 3. The height detection device 2 is mounted on the frame 1 and detects the height position of the packaging film 40 wrapped between the upper and lower ends of the stack 30 located on one side of the frame 1 along a first direction W. The film cutting device 3 is vertically mounted on the frame 1 and includes a film cutting component 31 to break the packaging film 40 detected by the height detection device 2.

[0083] By setting a height detection device 2, the height position of the non-integral packaging film 40 on the stack 30 is detected, so that the film cutting device 3 can accurately and efficiently cut the packaging film 40 at different height positions. Therefore, it is convenient to remove non-integral wrapping packaging films of multiple specifications and different positions. This is beneficial to improve the working flexibility of the film removal equipment 10 and the film removal system 100, expand the application range of the film removal equipment 10 and the film removal system 100, and improve the film removal efficiency of the film removal equipment 10 and the film removal system 100.

[0084] To achieve the detection of the height position of the packaging film at 40°, in some embodiments, see [reference needed]. Figure 1 The height detection device 2 includes a first detection element 21 and a second detection element 22. The first detection element 21 detects the height of the stack 30, and the second detection element 22 detects the height position of the packaging film 40 on the stack 30 after the first detection element 21 detects the height of the stack 30.

[0085] In the above scheme, the height detection device 2 does not obtain the height position of the packaging film 40 by directly detecting the packaging film 40, but adopts a two-stage detection method to detect the height position of the packaging film. The first detection element 21 detects the stack height, which is the first stage of detection, equivalent to a coarse positioning, and can serve as the basis for the detection of the second detection element 22. The second detection element 22, after the first detection element 21 has detected the stack height, detects the height position of the packaging film 40 on the stack 30 based on the detected stack height, which is the second stage of detection, equivalent to a second fine positioning, and can finally determine the height position of the packaging film 40 on the stack 30. This two-stage inspection method, which proceeds from coarse to fine, is beneficial for improving inspection accuracy. Moreover, since the second inspection component 22 only needs to perform inspection within the stack height range determined by the first inspection component 21, it does not need to perform full-stroke inspection. For example, the second inspection component 22 only needs to perform inspection within a preset height range below the top of the stack detected by the first inspection component 21 (which can be preset to correspond to the maximum height range that the packaging film 40 may be in) to determine the height position of the packaging film 40 on the stack 30. Therefore, it is beneficial to shorten the inspection time and improve the inspection efficiency.

[0086] During the process of wrapping the packaging film 40 around the stack 30, there is a general height range, for example, it is usually between the top two layers of boxes. However, the specific position may vary, it may be higher or lower. Therefore, a packaging film height range that can cover all situations can be determined in advance. Then, the second inspection piece 22 can be inspected within the corresponding range. In this way, the second inspection piece 22 does not need to be inspected within the entire stack height range, which can effectively improve the inspection efficiency and accuracy.

[0087] It is evident that by setting up the first detection element 21 and the second detection element 22, and adopting a two-stage detection method of coarse and fine detection, the detection of the packaging film at the height position of 40 can be achieved efficiently and accurately. This is beneficial for further facilitating the removal of non-integral wrapping packaging films of various specifications and positions.

[0088] As an example of the first detection element 21 mentioned above, see Figure 1 The first detection element 21 includes a first photoelectric sensor 211. The first photoelectric sensor 211 detects the height of the stack by sending light to the stack 30. Specifically, the detection of the stack 30 can be achieved by determining whether the light sent by the first photoelectric sensor 211 is blocked or interrupted by the stack 30.

[0089] Additionally, as an example of the second inspection piece 22 mentioned above, see [link to relevant documentation]. Figure 1The second detection element 22 includes a color mark sensor 221. The color mark sensor 221 detects the height position of the packaging film 40 by projecting a laser beam onto the packaging film 40. Since the packaging film 40 and the stack 30 have different reflective properties, the color mark sensor 221 can determine whether there is a film or not based on the difference in light reflection between the two, thus detecting the height position of the packaging film 40. Using the color mark sensor 221 allows for convenient and accurate detection of the packaging film 40, especially effectively solving the detection problem of transparent packaging films 40. Light can pass through transparent packaging films 40, making it difficult to detect them using photoelectric sensors. However, the color mark sensor 221 effectively solves this problem by utilizing the difference in reflective properties between the packaging film 40 and the stack 30, enabling convenient and accurate detection of the packaging film 40.

[0090] In the case where the second detection element 22 includes a color mark sensor 221, see [link / reference]. Figure 1 The height detection device 2 may further include an auxiliary light source 23, which provides auxiliary illumination for the color mark sensor 221. This reduces the impact of ambient light variations on the detection results of the color mark sensor 221. In particular, it prevents insufficient ambient light from causing the color mark sensor 221 to have difficulty detecting effectively. Therefore, it is beneficial to achieve more accurate and reliable detection of the height position of the packaging film.

[0091] In embodiments where the height detection device 2 includes a second detection element 22, the second detection element 22 can be configured to extend or retract relative to the frame 1 along a first direction W to approach or move away from the packaging film 40 on the stack 30. This allows the second detection element 22 to approach the packaging film 40 for accurate height detection when needed, while also allowing it to move away from the packaging film 40 before and after detection. This facilitates both the detection of the packaging film's height by the second detection element 22 and the orderly execution of other steps. In particular, when the second detection element 22 includes a color mark sensor 221, the color mark sensor 221 requires a certain distance from the packaging film 40 to perform its detection function. Therefore, configuring the second detection element 22 to approach or move away from the packaging film 40 makes it easier for the color mark sensor 221 to accurately detect the packaging film 40 without affecting other operations.

[0092] In the foregoing embodiments, the height detection device 2 can be vertically mounted on the frame 1. This makes it easier for the height detection device 2 to detect packaging film 40 at different height positions. Moreover, the height detection device 2 can only be lowered to a lower detection position when detection is required, while it is in a higher initial position before detection begins to avoid obstacles, thus facilitating other steps such as the transportation of the stack 30.

[0093] The height detection device 2, which can be raised and lowered, can rise and fall sequentially or synchronously with the film-breaking device 3. When the height detection device 2 and the film-breaking device 3 rise and fall synchronously, the film-breaking device 3 can move to the height of the packaging film 40 just after the height detection device 2 detects it, and promptly break the packaging film 40. Since the film-breaking device 3 rises and falls at the same time as the height detection device 2, it does not require additional time, thus improving efficiency.

[0094] In the foregoing embodiments, the film-breaking device 3 breaks the packaging film 40 via the film-breaking component 31. The film-breaking component 31 can be used in various ways to break the packaging film 40. For example, in some embodiments, the film-breaking component 31 includes a heating wire 311 (see...). Figure 8 In some embodiments, the heating wire 311 heats and melts the packaging film 40, thus breaking the packaging film 40. In this case, the film-breaking component 31 uses heating to melt the film, achieving the breaking of the packaging film 40. In other embodiments, the film-breaking component 31 includes a cutter (not shown), which cuts the packaging film 40 to break it. In this case, the film-breaking component 31 uses a cutting method to break the packaging film 40. In yet another embodiment, the film-breaking component 31 includes both a cutter and the heating wire 311, allowing for the simultaneous use of both cutting and heating to break the packaging film 40.

[0095] As an example of the membrane-breaking device 3 in the foregoing embodiments, see Figure 6 as well as Figure 8 and Figure 9 The film-cutting device 3 includes not only a film-cutting component 31, but also a film-cutting telescopic drive mechanism 32. The film-cutting telescopic drive mechanism 32 is drivenly connected to the film-cutting component 31 and drives the film-cutting component 31 to extend or retract relative to the frame 1 along the first direction W, so that the film-cutting component 31 moves closer to or further away from the packaging film 40 on the stack 30. Based on this, the film-cutting component 31 can automatically move closer to or further away from the packaging film 40 on the stack 30 under the drive of the film-cutting telescopic drive mechanism 32, flexibly and conveniently meeting different needs when film cutting is required and when film cutting is not required, thereby improving efficiency.

[0096] To further improve efficiency, the film removal equipment 10 may include not only the frame 1, the height detection device 2, and the film cutting device 3, but also the film removal device 4. The film removal device 4 is vertically mounted on the frame 1 and includes a film removal mechanism 41. The film removal mechanism 41 is used to engage with the packaging film 40 before and / or after the film cutting device 3 cuts the packaging film 40 and to separate the packaging film 40 from the stack 30.

[0097] The film removal device 4 separates the packaging film 40 from the stack 30 before the film cutting device 3 cuts it. This ensures that when the film cutting device 3 cuts the packaging film 40, the packaging film 40 is no longer attached to the stack 30, but is separated from the stack 30 by a distance. In this way, the film cutting device 3 can act only on the packaging film 40, cutting the packaging film 40 more quickly and effortlessly. Moreover, it helps to prevent the film cutting device 3 from damaging the stack 30.

[0098] After the packaging film 40 is broken by the film cutting device 3, the film removal device 4 separates the packaging film 40 from the stack 30, that is, it removes the broken packaging film 40 from the stack 30. This can realize the automatic removal of the packaging film 40 from the stack 30. Compared with the situation where the broken packaging film 40 falls off by itself under the action of gravity or is removed manually, the degree of automation is higher and it is more conducive to improving efficiency. Moreover, the film removal device 10 can integrate the detection, film cutting and film removal functions into one, with a higher degree of integration and richer functions.

[0099] The film removal device 4 uses a film removal mechanism 41 to engage with and separate the packaging film 40. As an example, the film removal mechanism 41 may include a clamping mechanism that clamps the packaging film 40 to engage with it; or, the film removal mechanism 41 may include a suction device 411 that adsorbs the packaging film 40 to engage with it; or, the film removal mechanism 41 may simultaneously include both a clamping mechanism and a suction device 411 to achieve engagement with the packaging film 40 using both clamping and adsorption methods.

[0100] In the membrane removal equipment 10, the number of membrane removal devices 4 is not limited; there can be one, two, or more. For example, see... Figures 1-5 In some embodiments, the film removal device 10 includes at least two film removal devices 4, which are arranged at intervals to engage with different parts of the packaging film 40. Based on this, when the packaging film 40 needs to be separated, there are more engagement points between the film removal device 10 and the packaging film 40, resulting in a stronger bond and making it easier for the film removal device 10 to reliably separate the packaging film 40 from the stack 30. Furthermore, by engaging different parts of the packaging film 40 with different film removal devices 4, the film removal device 10 also allows the different film removal devices 4 to straighten the portions between different engagement points with the packaging film 40, facilitating further processing of the removed packaging film 40, such as placing the removed packaging film 40 onto the film winding mechanism 5, which will be mentioned below.

[0101] When the film removal equipment 10 includes at least two film removal devices 4, the film cutting device 3 can be located between the different film removal devices 4, or it can be located on one side of all the film removal devices 4. For example, see Figures 1-3In some embodiments, the film-breaking device 3 is located on one side of the at least two film-removing devices 4 along the arrangement direction of the at least two film-removing devices 4.

Figure 2 The position C where the film-cutting device 3 breaks the packaging film 40 is located at the position where the different film-removing devices 4 are engaged with the packaging film 40 (e.g., Figure 2 The outer side of positions A and B in the diagram is such that after the packaging film 40 is broken, the portion of the packaging film 40 located between different film removal devices 4 can still be well held by the film removal device 4 (e.g., straightened), thereby facilitating other processing of the removed packaging film 40 by the film removal device 4, such as placing the removed packaging film 40 onto the film winding mechanism 5 mentioned below.

[0102] In the foregoing embodiments, see Figure 6 The film removal device 4 may include not only the film removal mechanism 41, but also a film removal telescopic drive mechanism 42. The film removal telescopic drive mechanism 42 is drivenly connected to the film removal mechanism 41 and drives the film removal mechanism 41 to extend or retract relative to the frame 1 along the first direction W, so that the film removal mechanism 41 approaches or moves away from the packaging film 40 on the stack 30. Based on this, the film removal mechanism 41 can automatically approach or move away from the packaging film 40 on the stack 30 under the drive of the film removal telescopic drive mechanism 42, flexibly and conveniently meeting different needs when separation of the packaging film 40 from the stack 30 is required and not required, thereby improving efficiency. When the film removal device 10 includes at least two film removal mechanisms 41, each film removal mechanism 41 is equipped with a film removal telescopic drive mechanism 42, and each film removal mechanism 41 is driven by a different film removal telescopic drive mechanism 42, which can extend or retract independently. This makes it convenient for different film removal mechanisms 41 to retract one after another before the film cutting device 3 cuts the packaging film 40, reducing the tensile force on the packaging film 40 before it is cut, and reducing the risk of the uncut packaging film 40 falling off.

[0103] In addition, to improve the operational reliability of the film removal device 4, as a further improvement to the film removal device 4 in the aforementioned embodiments, see [reference needed]. Figure 5 and Figure 10 The film removal device 4 also includes a first presence detection device 43, which detects whether the packaging film 40 is located on the film removal mechanism 41. This prevents the packaging film 40 from falling off the film removal mechanism 41, thereby effectively improving the operational reliability of the film removal device 4.

[0104] See also Figure 5 and Figure 10As an example of a first in-situ detection device 43, the first in-situ detection device 43 includes at least one of an ultrasonic sensor 431 and a pressure sensor 432. The ultrasonic sensor 431 detects whether the packaging film 40 is on the film removal mechanism 41 by emitting ultrasonic waves towards the packaging film 40; the pressure sensor 432 detects whether the packaging film 40 is on the film removal mechanism 41 by detecting the pressure on the film removal mechanism 41. When the first in-situ detection device 43 includes both the ultrasonic sensor 431 and the pressure sensor 432, the first in-situ detection device 43 can perform dual detection of the packaging film 40, resulting in more accurate and reliable detection results and more effectively preventing the packaging film 40 from falling off the film removal mechanism 41.

[0105] Since the packaging film 40 is usually quite soft, it is easy for it to get caught on the stack 30 during the separation process of the film removal device 4. Therefore, in order to solve this problem, see [reference needed]. Figures 1-4 In some embodiments, the film removal device 10 includes an air blowing device 72, which blows air onto the packaging film 40 during the process of the film removal device 4 separating the packaging film 40 from the stack 30. During the separation process of the packaging film 40 by the film removal device 4, the air blowing device 72 effectively prevents the packaging film 40 from getting caught on the stack 30. In particular, it effectively prevents the packaging film 40 from getting caught on the stack 30 during the process of the film removal device 4 removing the broken packaging film 40 from the stack 30, thus avoiding affecting the smooth removal of the packaging film 40. Moreover, the stack 30 is usually not completely flat, but may have sharp corners due to local unevenness of the cargo box. In this case, the packaging film 40 is more likely to get caught on the stack 30, making it difficult to remove. Therefore, the purpose of providing the air blowing device 72 to blow air onto the packaging film 40 is even more significant.

[0106] The blowing device 72 may include an air nozzle 721 for blowing air onto the packaging film 40. The number of air nozzles 721 in the blowing device 72 may be one, two, or more. When the blowing device 72 includes at least two air nozzles 721, see [reference needed]. Figure 1 and Figure 2 In some embodiments, at least two air nozzles 721 are arranged at intervals around the perimeter of the stack 30 to blow air onto different positions of the packaging film 40. In this way, the air blowing device 72 can blow air around the perimeter of the packaging film 40, which can more reliably prevent the packaging film 40 from getting caught on the stack 30, thereby improving the packaging film separation efficiency more effectively.

[0107] Additionally, to facilitate the blowing device 72 blowing air during the separation of the packaging film 40 by the film removal device 4, see [link to relevant documentation]. Figures 1-4In some embodiments, the film removal device 10 includes a frame 71 connected to the frame 1 and raised and lowered synchronously with the film removal device 4. The frame 71 allows the stack of goods 30 to pass through, and the air blowing device 72 is disposed on the frame 71.

[0108] In the above configuration, since the air blowing device 72 is mounted on the frame 71, and the frame 71 and the film removal device 4 are raised and lowered synchronously, the air blowing device 72 can be raised and lowered synchronously with the film removal device 4. This allows the air blowing device 72 and the film removal device 4 to reach the height position of the packaging film 40 simultaneously, thus enabling timely air blowing during the process of the film removal device 4 separating the packaging film 40, thereby improving efficiency. Moreover, since the frame 71 allows the stack of goods 30 to pass through, the frame 71 and the air blowing device 72 will not interfere with each other, facilitating the smooth raising and lowering of the film removal equipment 10 and enabling the air blowing device 72 to achieve a better blowing effect. In particular, in this case, all the air nozzles 721 of the air blowing device 72 only need to be spaced out on the frame 71 to achieve a spaced arrangement around the perimeter of the stack of goods 30, blowing air onto the packaging film 40 from all sides, reliably preventing the packaging film 40 from getting caught.

[0109] In the foregoing embodiments, both the film removal device 4 and the film cutting device 3 are height-adjustable to facilitate the breaking and separation of the packaging film 40 at different heights. The lifting and lowering of the film removal device 4 and the film cutting device 3 can be synchronized or asynchronous. When the film removal device 4 and the film cutting device 3 lift and lower synchronously, the efficiency is higher and the structure is simplified.

[0110] For example, see Figures 1-4 In some embodiments, the film removal equipment 10 includes a lifting frame 13, which is movably mounted on the frame 1. Both the film removal device 4 and the film cutting device 3 are mounted on the lifting frame 13, allowing the film removal device 4 and the film cutting device 3 to move up and down synchronously. In this way, the film removal device 4 and the film cutting device 3 are integrated onto the lifting frame 13. Only by driving the lifting frame 13 to move up and down, synchronous movement of the film removal device 4 and the film cutting device 3 can be achieved. This not only improves the synchronization of movement but also eliminates the need for separate lifting drive mechanisms for the film removal device 4 and the film cutting device 3, thus simplifying the structure.

[0111] When the lifting frame 13 is provided, other mechanisms that lift and lower synchronously with the film cutting device 3 or the film removal device 4, such as the height detection device 2, the frame 71, the air blowing device 72, and the stop 73 and the take-up mechanism 6 mentioned below, can also be provided on the lifting frame 13 to achieve more synchronized lifting and lowering based on a simpler structure.

[0112] The packaging film 40 removed from the stack 30 by the film removal device 4 would occupy a large amount of space if not processed. Therefore, to save space, see [reference needed]. Figures 1-7In some embodiments, the film removal device 10 includes not only a film removal device 4, but also a film winding mechanism 5. The film winding mechanism 5 is mounted on the frame 1 and is used to wind the packaging film 40 removed from the stack 30 by the film removal device 4 into a film roll. In this way, the film removal device 10 integrates not only packaging film height detection, film breaking and film removal functions, but also film winding function, so that the packaging film 40 detached from the stack 30 can be wound into a roll, reducing space occupation.

[0113] To achieve the film winding function of the film winding mechanism 5, see [link to relevant documentation]. Figure 3 as well as Figure 12 and Figure 13 In some embodiments, the film winding mechanism 5 includes a winding mechanism 51, which is rotatably mounted on the frame 1. During rotation, the winding mechanism 51 winds the packaging film 40 removed from the stack 30 by the film removal device 4 into a film roll. Thus, the rotating winding mechanism 51 can conveniently wind the removed packaging film 40 into a film roll, achieving the corresponding film winding function. The rotation of the winding mechanism 51 can be driven by a winding drive mechanism 52 to automatically rotate the winding mechanism 51 and automatically wind the packaging film 40 into a roll, improving efficiency.

[0114] As an example of the winding mechanism 51, see Figure 12 and Figure 13 In some embodiments, the winding mechanism 51 includes a first winding rod 511 and a second winding rod 512. The first winding rod 511 and the second winding rod 512 are rotatably mounted on the frame 1, and a receiving space 513 is provided between the first winding rod 511 and the second winding rod 512, so that the packaging film 40 removed from the stack 30 by the film removal device 4 can be placed into the receiving space 513 between the first winding rod 511 and the second winding rod 512, and wound into a film roll during the rotation of the first winding rod 511 and the second winding rod 512. In this way, simply placing the packaging film 40 into the receiving space 513 between the first winding rod 511 and the second winding rod 512 and driving the first winding rod 511 and the second winding rod 512 to rotate can wind the originally unfolded packaging film 40 into a roll, forming a film roll, which is simple, convenient, and highly efficient.

[0115] The packaging film 40 can be manually placed into the receiving space 513, or it can be automatically placed into the receiving space 513 by the film removal device 4 to further improve efficiency. When the packaging film 40 is placed into the receiving space 513 by the film removal device 4, see [link to relevant documentation]. Figures 1-3The film winding mechanism 5 can be positioned below the film removal device 4, allowing the film removal device 4 to sequentially complete the two operations of removing the packaging film 40 and placing the removed packaging film 40 into the receiving space 513 simply by continuously descending. This makes control easier and more efficient. Alternatively, in some embodiments, the film winding mechanism 5 can be positioned above the film removal device 4, allowing the film removal device 4 to place the removed packaging film 40 into the receiving space 513 by moving upwards.

[0116] To ensure a smooth and efficient film rolling process, please refer to [link / reference needed]. Figures 1-4 In some embodiments, the film removal device 10 includes a stop 73. The stop 73 stops the packaging film 40 during the winding process of the film winding mechanism 5 to prevent it from detaching from the winding mechanism 5. Thus, under the action of the stop 73, the packaging film 40 is less likely to detach from the winding mechanism 5 during winding and can be reliably held on it. Therefore, it is easier for the winding mechanism 5 to wind it into a film roll, resulting in higher efficiency.

[0117] Among them, the stop member 73 can stop the packaging film 40 from top to bottom, from bottom to top, or from both directions simultaneously.

[0118] As an example, see Figures 1-4 During the winding process of the film winding mechanism 5, the stop member 73 acts from above to prevent the packaging film 40 from detaching from the top of the film winding mechanism 5 during the winding process. In this way, under the action of the stop member 73, the packaging film 40 will not detach from the top of the film winding mechanism 5, and the film winding mechanism 5 can wind the packaging film 40 into a film roll more efficiently.

[0119] In an embodiment where the stop member 73 stops the packaging film 40 from above, see [reference needed]. Figures 1-3 The stop member 73 can be raised and lowered on the frame 1. This allows the stop member 73 to be lowered to the stop position when a stop is needed, pressing on the film roll to achieve a stop from top to bottom. When a stop is not needed, the stop member 73 can be kept in a higher position to avoid other structural components and facilitate the operation of other structural components.

[0120] The lifting and lowering of the stop member 73 can be synchronized with the film removal device 4, so that when the film removal device 4 places the packaging film 40 onto the film winding mechanism 5, the stop member 73 reaches the stop position simultaneously to stop, thereby improving efficiency and achieving a better stopping effect.

[0121] Additionally, see Figure 3In the case where the film winding mechanism 5 includes a winding drive mechanism 52, the film winding mechanism 5 may further include a protective member 53, which is located above the winding drive mechanism 52, with at least a portion of the winding mechanism 51 located above the protective member 53. Based on this, the protective member 53 can support and stop the packaging film 40 from below during the winding process, preventing the packaging film 40 from entering the winding drive mechanism 52, thus avoiding affecting the smooth completion of the winding process.

[0122] Among them, see Figure 3 In some embodiments, the protective member 53 is provided with a downwardly recessed groove 531. The groove 531 facilitates the insertion of a hand or tool (such as the second clamping member 62 of the take-up mechanism 6 mentioned below), thus facilitating the removal of the wound film roll from the winding mechanism 51 after the winding mechanism 51 has wound the packaging film 40 into a film roll.

[0123] The unwinding action can be performed manually by staff or automatically by the film removal equipment 10.

[0124] For easier scroll retrieval, please refer to [link / reference]. Figure 12 and Figure 13 In some embodiments, the film removal device 10 includes a second presence detection device 54, which detects whether the film roll is located on the film winding mechanism 5. This allows the film roll to be retrieved only when the second presence detection device 54 detects that the film roll is on the film winding mechanism 5, preventing the film roll from accidentally detaching from the film winding mechanism 5 and thus ensuring successful retrieval. The second presence detection device 54 can take various structural forms. For example, see [link to example]. Figure 12 and Figure 13 The second presence detection device 54 includes a second photoelectric sensor 541. Since the packaging film 40 is no longer transparent after being wound into a roll, the second photoelectric sensor 541 can be used to successfully detect whether the roll is in place. The device has a simple structure, low cost, and high accuracy.

[0125] Additionally, to achieve automatic roll-fetching, see [link to documentation]. Figures 1-7 In some embodiments, the film removal device 10 includes a take-up mechanism 6, which is mounted on the frame 1 and used to remove the film roll from the film winding mechanism 5. Thus, the film removal device 10 not only integrates functions such as packaging film height detection, film breaking, film removal, and film winding, but also integrates a take-up function, enabling automatic removal of the film roll, resulting in richer functionality and higher efficiency.

[0126] The winding mechanism 6 can adopt various structural forms.

[0127] For example, in some embodiments, the roll-up mechanism 6 includes a robotic arm that removes the film roll from the film-winding mechanism 5 by grasping the film roll.

[0128] For example, see Figure 14 and Figure 15 In some embodiments, the film reeling mechanism 6 includes a first clamping member 61, a second clamping member 62, and a swing drive mechanism 63. The first clamping member 61 and the second clamping member 62 are arranged sequentially from top to bottom and face each other. The swing drive mechanism 63 is drivenly connected to the first clamping member 61 and the second clamping member 62 and drives the first clamping member 61 and the second clamping member 62 to swing relative to each other in the vertical direction H to clamp or release the film roll. The film reeling mechanism 6 is vertically and vertically mounted on the frame 1 to drive the film roll clamped between the first clamping member 61 and the second clamping member 62 away from the film winding mechanism 5. In this way, the first clamping member 61 and the second clamping member 62 swing towards each other in the vertical direction H to clamp the film roll and drive the film roll to rise, thereby removing the film roll from the film winding mechanism 5, which is simple and efficient. Furthermore, the first clamping member 61 and the second clamping member 62 swing in opposite directions in the vertical direction H to release the film roll, which is convenient for subsequent processing such as collection of the removed film roll. The first clamping member 61 and the second clamping member 62 hold the membrane roll in a way that is less likely to damage it and makes it easier to reuse the membrane roll in the future.

[0129] The first clamping member 61 and the second clamping member 62 can adopt various structural forms such as plate or rod. For example, see Figure 14 and Figure 15 In some embodiments, the first clamping member 61 and / or the second clamping member 62 includes at least two clamping rods 611, which are spaced apart. This facilitates the clamping of the film roll located between the first and second clamping rods 511 and 512. Moreover, the first clamping member 61 and / or the second clamping member 62 can engage with different positions of the film roll through different clamping rods 611, applying force to the film roll at at least two locations. Therefore, it is easier for the unwinding mechanism 6 to firmly engage with the film roll, thereby smoothly and reliably removing the film roll. Furthermore, configuring the first clamping member 61 to include clamping rods 611 particularly facilitates the engagement of the first clamping member 61 with the groove 531 on the protective member 53 of the film winding mechanism 5, smoothly realizing the unwinding action.

[0130] To facilitate the relative oscillation of the first clamping member 61 and the second clamping member 62 in the vertical direction H for clamping or releasing the film roll, see [reference needed]. Figure 14In some embodiments, the swing drive mechanism 63 includes a first swing drive mechanism 631 and a second swing drive mechanism 632. The first swing drive mechanism 631 is driven to the first clamping member 61 to swing the first clamping member 61 downward, so that the first clamping member 61 and the second clamping member 62 clamp the film roll on the film winding mechanism 5. The second swing drive mechanism 632 is driven to the second clamping member 62 to swing the second clamping member 62 downward, so that the first clamping member 61 and the second clamping member 62 release the film roll from the film winding mechanism 5. In this way, during operation, the take-up mechanism 6 can be controlled to reach the take-up height position, so that the second clamping member 62 is located below the film roll. Then, the first swing drive mechanism 631 is controlled to move, driving the first clamping member 61 to swing downward and clamp the film roll. Then, the first clamping member 61 and the second clamping member 62 are controlled to move the film roll up together, so that the film roll leaves the film winding mechanism 5. After the first clamping member 61 and the second clamping member 62 bring the film roll to a suitable position for releasing the film roll, the second swing drive mechanism 632 is controlled to move, driving the second clamping member 62 to swing downward and release the clamp on the film roll, thus releasing the film roll. The whole process is simple, orderly, efficient and convenient.

[0131] In the foregoing embodiments, the take-up mechanism 6 detaches the film roll from the film winding mechanism 5 by lifting and lowering. The lifting and lowering of the take-up mechanism 6 can be synchronized with or asynchronous with the film cutting device 3. When the take-up mechanism 6 and the film cutting device 3 lift and lower synchronously, they can be driven by the same lifting mechanism to simplify the structure. When the take-up mechanism 6 and the film cutting device 3 lift and lower asynchronously, their actions can be relatively independent, with film cutting and take-up actions occurring simultaneously. This allows the film cutting device 3 to disconnect the next packaging film 40 while the take-up mechanism 6 is removing the previous film roll, effectively accelerating the operating cycle and improving efficiency.

[0132] For the convenience of the retrieving mechanism 6 in performing the retrieving action, see [link / reference]. Figure 14 and Figure 15 In some embodiments, the film removal device 10 includes a take-up telescopic drive mechanism 64, which is drivenly connected to the take-up mechanism 6 and drives the take-up mechanism 6 to extend or retract relative to the frame 1 along a first direction W, so that the take-up mechanism 6 approaches and moves away from the film winding mechanism 5. In this way, the take-up mechanism 6 can automatically approach or move away from the film winding mechanism 5 under the drive of the take-up telescopic drive mechanism 64, flexibly and conveniently meeting different needs during and before and after take-up, thereby improving efficiency.

[0133] The membrane roll removed by the unloading mechanism 6 can be collected by the collecting component 9 to further reduce space occupation and facilitate subsequent unified processing of the membrane roll.

[0134] When collecting the film roll using the collector 9, the film roll can be placed into the collector 9 manually or automatically. For example, in some embodiments, the take-up mechanism 6 is configured not only to remove the film roll from the film winding mechanism 5, but also to place the film roll removed from the film winding mechanism 5 into the collector 9 for collection by the collector 9. In this case, the take-up mechanism 6 integrates the take-up and unwinding functions into one unit, which can automatically remove the film roll from the film winding mechanism 5 and automatically place the removed film roll into the collector 9, resulting in richer functionality and higher efficiency.

[0135] To facilitate the placement of the film roll into the collection unit 9 by the roll-up mechanism 6, see [link / reference]. Figure 7 as well as Figure 14 and Figure 15 In some embodiments, the film removal device 10 includes a rotary drive mechanism 65, which is motive-connected to the take-up mechanism 6 and drives the take-up mechanism 6 to rotate so that the take-up mechanism 6 rotates to a position where the film roll is placed in the collection member 9. Based on this, under the action of the rotary drive mechanism 65, the take-up mechanism 6 can rotate away from the position directly above the film winding mechanism 5 and rotate to a position that facilitates the placement of the film roll into the collection member 9.

[0136] As mentioned earlier, the take-up mechanism 6 may need to move the film roll up, down, and rotate. To prevent the film roll from accidentally detaching from the take-up mechanism 6 during operation, thus affecting the smooth functioning of the mechanism, please refer to [reference needed]. Figure 14 In some embodiments, the film removal device 10 includes a third presence detection device 66, which detects whether the film roll is located on the take-up mechanism 6. This allows for timely detection of whether the film roll has accidentally detached from the take-up mechanism 6, effectively ensuring that the film roll remains on the take-up mechanism 6 throughout the entire process after the take-up mechanism 6 engages with the film roll. This facilitates the take-up mechanism 6 in driving the film roll to perform lifting, rotating, and other actions, smoothly achieving the take-up and unwinding functions.

[0137] For example, see the third in-situ detection device 66. Figure 14 The third presence detection device 66 includes a third photoelectric sensor 661. After the packaging film 40 rolls are wound into a film roll, they are no longer transparent. Therefore, the presence of the film roll can be easily detected by using the third photoelectric sensor 661. The device has a simple structure, low cost, and high accuracy.

[0138] Next, combine Figures 1-15 The embodiments shown further illustrate the membrane removal system 100 and membrane removal equipment 10 of this application.

[0139] like Figures 1-3 As shown, in this embodiment, the membrane removal system 100 includes components along a first direction W (in... Figure 1Specifically, a conveying device 20 and a film removal device 10 are arranged opposite each other in a left-right direction. The conveying device 20 is used to convey stacks 30 with non-integral packaging film 40. The film removal device 10 is used to remove and collect the non-integral packaging film 40 on the stacks 30 on the conveying device 20. In this embodiment, the first direction W is perpendicular to the vertical direction H and the conveying direction of the conveying device 20.

[0140] The conveying equipment 20 can be any conveying mechanism, such as a conveyor chain or conveyor belt, as long as it can transport the stack of goods 30. Therefore, the structure of the conveying equipment 20 will not be described in detail here. The structure of the film removal equipment 10 will be the focus of the following description.

[0141] like Figures 1-15 As shown, in this embodiment, the film removal equipment 10 includes a frame 1, a lifting frame 13, a guide rail 14, a lifting drive mechanism 15, a lifting limit 16, a height detection device 2, a film breaking device 3, a film removal device 4, a film winding mechanism 5, a roll-up mechanism 6, a frame 71, an air blowing device 72, a stop 73, and a collection component 9.

[0142] Frame 1 is used to support other components and provide a mounting base for them. For example... Figure 1 and Figure 2 As shown, in this embodiment, the frame 1 is located on one side of the conveying device 20 along the first direction W (in Figure 1 (Specifically, the left side). And, as... Figure 2 As shown, in this embodiment, the bottom of the frame 1 is provided with a foot cup 11 and a pressure block 12. The height of the foot cup 11 is adjustable, so that the height of the frame 1 is adjustable. The pressure block 12 is disposed above the foot cup 11 to limit the position of the foot cup 11.

[0143] The lifting frame 13 is mounted on the machine frame 1 to support the height detection device 2, film cutting device 3, film removal device 4, winding mechanism 6, frame 71, air blowing device 72, and stop 73, and to achieve synchronous lifting and lowering of the height detection device 2, film cutting device 3, film removal device 4, winding mechanism 6, frame 71, air blowing device 72, and stop 73. Figure 1 and Figure 2 As shown, in this embodiment, the lifting frame 13 is connected to the frame 1 via a vertically extending guide rail 14, allowing the lifting frame 13 to be raised and lowered relative to the frame 1. This enables the lifting frame 13 to be raised and lowered on the frame 1, facilitating the synchronous raising and lowering of the height detection device 2, film cutting device 3, film removing device 4, roll taking mechanism 6, frame 71, air blowing device 72, and stop 73. Furthermore, as... Figure 1As shown, in this embodiment, the lifting frame 13 is equipped with a cable drag chain 85 and a cable clamp 84. The cable drag chain 85 is used to drag the cables of the film removal equipment 10 (e.g., the wires required for the motor, the signal lines required for the sensors, and the pipelines required for the drive cylinder) to accommodate the extension and retraction of the cables during the operation of each mechanism. The cable clamp 84 is used to engage with the cables of the film removal equipment 10 to limit the cables of the film removal equipment 10 and prevent tangling.

[0144] The lifting drive mechanism 15 is mounted on the frame 1 and is drivenly connected to the lifting frame 13. By driving the lifting frame 13 to lift, it synchronously lifts and lowers the height detection device 2, film cutting device 3, film removing device 4, roll taking mechanism 6, frame 71, air blowing device 72, and stop member 73 located on the lifting frame 13. Figures 1-3 As shown, in this embodiment, the lifting drive mechanism 15 includes a lifting motor 152 and a chain drive mechanism 151. The lifting motor 152 is driven to the lifting frame 13 via the chain drive mechanism 151 to drive the lifting frame 13 to rise and fall.

[0145] Lifting limit 16 (see) Figure 2 It is installed on the frame 1 to limit the lifting displacement of the lifting frame 13, thereby limiting the lifting displacement of the height detection device 2, film cutting device 3, film removal device 4, roll taking mechanism 6, frame 71, air blowing device 72 and stop 73.

[0146] The height detection device 2, film breaking device 3, film removal device 4, roll taking mechanism 6, frame 71, air blowing device 72 and stop 73 are all mounted on the lifting frame 13, together with the lifting frame 13, forming a lifting assembly, which together are lifted and lowered under the drive of the lifting drive mechanism 15.

[0147] The height detection device 2 is used to detect the height position of the packaging film 40, so as to facilitate the film cutting device 3 and the film removal device 4 to cut and remove the packaging film 40 at different height positions. Figure 1 As shown, in this embodiment, the height detection device 2 includes a first detection element 21, a second detection element 22, and an auxiliary light source 23. The first detection element 21, used to detect the height of the stack 30, is mounted on the frame 71 and includes a first photoelectric sensor 211. The first photoelectric sensor 211 is a through-beam photoelectric sensor, with its emitting and receiving parts disposed on opposite sides of the frame 71. This allows the light emitted by the first photoelectric sensor 211 to be blocked when the stack 30 passes through the frame 71, thereby detecting the stack 30 and determining its height. The second detection element 22 is used to detect the height position of the packaging film 40 after the first photoelectric sensor 211 detects the height of the stack 30. Figure 1As shown, in this embodiment, the second detection element 22 is a color mark sensor 221, which detects within a preset height range (corresponding to a preset packaging film range) below the top surface of the stack 30. Based on the different reflective properties of the packaging film 40 and the stack 30, it detects the packaging film 40 and accurately determines its height position. Figure 1 As can be seen, in this embodiment, the color mark sensor 221 is mounted on the film-cutting device 3. This allows the color mark sensor 221 to move up and down together with the film-cutting device 3, and also to move along the first direction W together with the film-cutting device 3, approaching and moving away from the packaging film 40. This facilitates the color mark sensor 221 moving along the first direction W to a suitable detection position before detection. The auxiliary light source 23 provides auxiliary illumination for the color mark sensor 221, enabling reliable detection even under insufficient natural light. Figure 1 As shown, in this embodiment, the auxiliary light source 23 is also disposed on the membrane cutting device 3 and is located on one side of the color mark sensor 221 along the second direction L. This facilitates the auxiliary light source 23 to provide sufficient illumination for the color mark sensor 221. The second direction L is perpendicular to both the first direction W and the vertical direction H. Figure 1 Specifically, the direction is front and back, and it is parallel to the conveying direction of the conveying equipment 20.

[0148] The film-cutting device 3 is used to cut the packaging film 40 on the stack 30 to facilitate the separation of the packaging film 40 from the stack 30. For example... Figure 10 and Figure 11 As shown, in this embodiment, the film-cutting device 3 includes a mounting base 33, a heating wire 311, and a film-cutting telescopic drive cylinder 321. The mounting base 33 is disposed on the lifting frame 13 to enable the film-cutting device 3 to be mounted on the lifting frame 13, allowing the film-cutting device 3 to rise and fall together with the lifting frame 13. The heating wire 311 is disposed on the mounting base 33 and serves as a film-cutting component 31, used to heat and melt the packaging film 40 to break the packaging film 40. The film-cutting telescopic drive cylinder 321 is also disposed on the mounting base 33 and serves as a film-cutting telescopic drive mechanism 32, driven by the heating wire 311, driving the heating wire 311 to extend or retract along the first direction W, so that the heating wire 311 can approach and move away from the packaging film 40, facilitating the heating wire 311 to melt the packaging film 40 when needed.

[0149] The film removal device 4 is used to separate the packaging film 40 from the stack 30 before and after the film cutting device 3 cuts the packaging film 40, so as to facilitate the film cutting device 3 to melt and cut the packaging film 40 and remove the cut packaging film 40. Figures 1-6 As shown, in this embodiment, the film removal device 10 includes two film removal units 4, which are arranged at intervals along the second direction L, and are located on the same side of the film cutting device 3 along the second direction L. Thus, as... Figure 2As shown, the two film removal devices 4 can engage with the packaging film 40 at positions A and B. The film cutting device 3 can cut the packaging film 40 at position C, on the side away from position B, outside the two film removal devices 4. This allows the portion of the packaging film 40 located between positions A and B to remain straight after the packaging film 40 is cut, facilitating the subsequent placement of the packaging film 40 between the first winding rod 511 and the second winding rod 512 of the film winding mechanism 5 by the two film removal devices 4.

[0150] Moreover, such as Figure 10 and Figure 11 As shown, in this embodiment, the two film removal devices 4 have the same structure, both including a film removal mechanism 41, a film removal telescopic drive mechanism 42, and a first in-situ detection device 43. The film removal mechanism 41 includes a film suction device 411, a vacuum generator 414, and an adsorption limiter 415. The film suction device 411 includes a suction cup seat 412 and a suction cup 413. The suction cup seat 412 is disposed on the lifting frame 13 to connect the film removal device 4 to the lifting frame 13, allowing the film removal device 4 to rise and fall together with the lifting frame 13. The suction cup 413, vacuum generator 414, and adsorption limiter 415 are all disposed on the suction cup seat 412. The suction cup 413 is used to adsorb the packaging film 40. In this embodiment, the suction cup seat 412 is provided with multiple suction cups 413, allowing the same film removal device 4 to adsorb the packaging film 40 at multiple locations. Vacuum generator 414 is in gas communication with suction cup 413, evacuating suction cup 413 to allow it to adsorb packaging film 40 under negative pressure. Adsorption limiter 415 limits the suction cup 413. Film removal telescopic drive mechanism 42 is mounted on suction cup base 412 and includes film removal telescopic drive cylinder 421. Film removal telescopic drive cylinder 421 is drivenly connected to film removal mechanism 41, which can drive film removal mechanism 41 to move along the first direction W, closer to or further away from packaging film 40, to facilitate adsorbing packaging film 40 when close and to pull packaging film 40 off the stack 30 when moving away. First in-situ detection device 43 is mounted on suction cup base 412 and includes ultrasonic sensor 431 and pressure sensor 432. After the suction cup 413 picks up the packaging film 40, the ultrasonic sensor 431 sends ultrasonic waves to the packaging film 40, and the pressure sensor 432 detects the pressure of the suction cup 413, thereby realizing dual detection of the packaging film 40 to determine whether the packaging film 40 is held on the film suction device 411, and to prevent the packaging film 40 from falling off accidentally during the operation of the film suction device 411.

[0151] In this embodiment, the film removal device 4 not only pulls the packaging film 40 from the stack 30 before it is broken, facilitating the breaking device 3 to break the film 40, but also removes the packaging film 40 from the stack 30 after it is broken. Furthermore, it sends the removed packaging film 40 to the film winding mechanism 5, where it is wound into a roll. The process of removing the packaging film 40 from the stack 30 and sending it to the film winding mechanism 5 is achieved through the lowering action of the film removal device 4.

[0152] During the descent of the film removal device 4 and the delivery of the packaging film 40 to the film winding mechanism 5, air is blown by the air blowing device 72 to prevent the packaging film 40 from getting caught on the stack 30, thus facilitating the smooth removal of the packaging film 40 from the stack 30 and delivery to the film winding mechanism 5. Figures 1-3 As shown, in this embodiment, the air blowing device 72 includes multiple air blowing components, all of which are mounted on a frame 71 connected to the lifting frame 13 and spaced apart around the perimeter of the frame 71. The frame 71 is square with a hollow center, allowing the stack of goods 30 to pass through. Each air blowing component has the same structure, including an air nozzle 721 and a connector 722. The air nozzle 721 is connected to an air source via the connector 722 to blow air onto the packaging film 40, facilitating the film removal device 4 to smoothly remove the packaging film 40 from the stack of goods 30 and send it to the film winding mechanism 5.

[0153] The film winding mechanism 5 is mounted on the frame 1 and located below the film unwinding device 4, and is used to wind the disconnected packaging film 40 into a film roll. See also Figure 12 and Figure 13 and combined Figure 1 and Figure 2As can be seen, in this embodiment, the film winding mechanism 5 includes a winding mechanism 51, a winding drive mechanism 52, and a protective member 53. The winding mechanism 51 includes a first winding rod 511 and a second winding rod 512. The first winding rod 511 and the second winding rod 512 are arranged at intervals along a first direction W, forming a receiving space 513 between them. Moreover, the first winding rod 511 and the second winding rod 512 are located between two film removal devices 4 along a second direction L, so that after the two film removal devices 4 adsorbed and disconnected the packaging film 40 descend directly, the portion of the packaging film 40 located between the two film removal devices 4 can be placed into the receiving space 513. The first winding rod 511 and the second winding rod 512 are rotatably arranged and drivenly connected to the winding drive mechanism 52, so that they rotate under the drive of the winding drive mechanism 52 to wind the packaging film 40 placed between them into a film roll. The winding drive mechanism 52 is located below the winding mechanism 51 and includes a winding motor 521 to drive the first winding rod 511 and the second winding rod 512 to rotate when the winding motor 521 rotates. The protective member 53 is configured as a protective cover, with its opening facing downwards and covering the winding drive mechanism 52. The first winding rod 511 and the second winding rod 512 pass through the protective member 53 from bottom to top, such that the lower ends of the first winding rod 511 and the second winding rod 512 are located below the protective member 53 and are driven and connected to the winding motor 521, while the upper ends of the first winding rod 511 and the second winding rod 512 extend above the protective member 53 and are exposed. Thus, the protective component 53 can provide a certain degree of protection for the winding drive mechanism 52 and provide a certain degree of support for the packaging film 40 during the winding process. Moreover, during the winding process, the protective component 53 can stop the packaging film 40 from below, preventing the packaging film 40 from getting tangled in the winding drive mechanism 52. This not only facilitates the smooth progress of the winding process and improves efficiency, but also avoids damage to the winding drive mechanism 52 due to the packaging film 40 getting tangled in, thereby improving structural reliability.

[0154] To further prevent the packaging film 40 from detaching from the winding mechanism 51 during the winding process, such as Figures 1-4 As shown, in this embodiment, the frame 71 is also provided with a stop 73. The stop 73 is initially located directly above the winding mechanism 51, and the middle of the stop 73 is hollowed out to form a through hole 731. In this way, when the stop 73 descends with the frame 71 to the height position of the winding mechanism 51, the first winding rod 511 and the second winding rod 512 of the winding mechanism 51 can pass through the through hole 731 of the stop 73, so that the stop 73 can press on the packaging film 40 placed between the first winding rod 511 and the second winding rod 512, and stop the packaging film 40 from above. In this way, the stop 73 can prevent the packaging film 40 from detaching from the first winding rod 511 and the second winding rod 512 from above, so as to facilitate the smooth progress of the winding process.

[0155] Since the protective element 53 and the stop element 73 can stop the packaging film 40 from the top and bottom sides, the packaging film 40 can be more reliably prevented from falling off the winding mechanism 51 during the winding process.

[0156] Depend on Figure 12 and Figure 13 As can be seen, in this embodiment, the protective member 53 is provided with a second presence detection device 54, which includes a second photoelectric sensor 541. The emitting part and the receiving part of the second photoelectric sensor 541 are located on both sides of the first winding rod 511 and the second winding rod 512 along the second direction L, and the emitted light can pass through the receiving space 513 between the first winding rod 511 and the second winding rod 512. Thus, when the film roll is located in the receiving space 513, the light from the second photoelectric sensor 541 is blocked, and the receiving part of the second photoelectric sensor 541 cannot receive the light. However, when the film roll is not in the receiving space 513, the light from the second photoelectric sensor 541 is not blocked, so the receiving part of the second photoelectric sensor 541 can receive the light. Therefore, the second photoelectric sensor 541 can determine whether the film roll is located on the winding mechanism 51 based on whether its receiving part receives the light, and thus determine whether the film roll has fallen off the winding mechanism 51, so as to facilitate the unwinding mechanism 6 to perform the unwinding action when the film roll has not fallen off.

[0157] The unwinding mechanism 6 is used to remove the film roll from the winding mechanism 5 and place it into the collecting container 9 for collection. For example... Figures 1-7 As shown, in this embodiment, the take-up mechanism 6 is mounted on the lifting frame 13, allowing it to rise and fall synchronously with the height detection device 2, the film cutting device 3, and the film removal device 4. This facilitates the take-up mechanism 6 descending to the take-up height position when take-up is required. Furthermore, in the second direction L, the take-up mechanism 6 is located between the two film removal devices 4, corresponding to the position of the film winding mechanism 5 in the second direction L. This ensures that after descending, the take-up mechanism 6 aligns with the film winding mechanism 5 in the second direction L, facilitating take-up.

[0158] Figure 14 and Figure 15 The structure of the winding mechanism 6 is further illustrated. For example... Figure 14 and Figure 15As shown, in this embodiment, the film take-up mechanism 6 includes a base 69, a first clamping member 61, a second clamping member 62, and a swing drive mechanism 63. The swing drive mechanism 63 includes a first swing drive mechanism 631 and a second swing drive mechanism 632. The base 69 is connected to the lifting frame 13 to realize the setting of the film take-up mechanism 6 on the lifting frame 13, so that the film take-up mechanism 6 can rise and fall together with the lifting frame 13. The first clamping member 61 and the second clamping member 62 are respectively disposed at the upper and lower ends of the base 69, facing each other vertically, and both can swing up and down relative to the base 69. The first swing drive mechanism 631 and the second swing drive mechanism 632 are both drive cylinders, and they are respectively driven connected to the first clamping member 61 and the second clamping member 62 to drive the first clamping member 61 and the second clamping member 62 to swing between a horizontal position and a swing position below their respective horizontal positions. In this way, the film roll can be clamped or released simply by controlling the swing of the first clamping member 61 and the second clamping member 62. Specifically, when unwinding is required, the second clamping member 62 is positioned below the film roll, and the first clamping member 61 is positioned above the film roll. The first clamping member 61 swings downward, thus clamping the film roll together with the second clamping member 62. When unwinding is required, the first clamping member 61 remains in the swinging position, and the second clamping member 62 swings downward, releasing the clamping effect on the film roll, allowing it to fall downward and detach from the unwinding mechanism 6.

[0159] Depend on Figure 14 and Figure 15 As can be seen, in this embodiment, both the first clamping member 61 and the second clamping member 62 include multiple clamping rods 611 arranged at intervals along the second direction L, and the clamping rods 611 of the first clamping member 61 and the second clamping member 62 are vertically aligned in a one-to-one correspondence. Thus, after the first clamping member 61 swings downward, each clamping rod 611 of the first clamping member 61 can clamp the film roll in a one-to-one correspondence with each clamping rod 611 of the second clamping member 62, achieving reliable engagement with the film roll, facilitating the removal mechanism 6 to take away the film roll, and effectively preventing the film roll from falling off during the transfer process. Furthermore, as... Figure 13 As shown, corresponding to the multiple clamping rods 611 of the second clamping member 62, the protective member 53 of the film winding mechanism 5 is provided with multiple grooves 531. The grooves 531 on the protective member 53 correspond one-to-one with the clamping rods 611 of the second clamping member 62, so that when it is necessary to unwind the film, each clamping rod 611 of the second clamping member 62 can extend into the corresponding groove 531 to hold the film roll. The grooves 531 are recessed downwards, open at the top, and open at both ends along the first direction W. In this way, after descending to the correct position, the clamping rods 611 of the second clamping member 62 can move in and out of the grooves 531 by moving along the first direction W. Furthermore, the first clamping member 61 and the second clamping member 62 move upwards to bring the clamped film roll away from the film winding mechanism 5, thereby achieving the purpose of unwinding the film.

[0160] In order to make the take-up mechanism 6 automatically move closer to or further away from the film winding mechanism 5 along the first direction W, such as Figure 14 and Figure 15 As shown, in this embodiment, the film removal device 10 includes a take-up telescopic drive mechanism 64, which is disposed on a base 69 and includes a take-up telescopic drive cylinder 641. The take-up telescopic drive cylinder 641 extends along a first direction W and is drivenly connected to a first clamping member 61 and a second clamping member 62 through the base 69, so that when the take-up telescopic drive cylinder 641 extends or retracts, it can drive the first clamping member 61 and the second clamping member 62 to move along the first direction W, thereby approaching and moving away from the film winding mechanism 5 in the first direction W.

[0161] During operation, after the first winding rod 511 and the second winding rod 512 wind the packaging film 40 into a film roll, the take-up mechanism 6 descends to a suitable take-up height, and the take-up telescopic drive cylinder 641 extends, causing the clamping rod 611 of the second clamping member 62 to extend into the groove 531, supporting the film roll from below. At this time, the first clamping member 61 is located above the film roll. In this case, the first swing drive mechanism 631 drives the first clamping member 61 to swing downward, so that the first clamping member 61 and the second clamping member 62 together clamp the film roll. Then, the take-up mechanism 6 moves upward, moving the film roll above the first winding rod 511 and the second winding rod 512, so that the film roll is detached from the film winding mechanism 5. After that, the take-up telescopic drive cylinder 641 retracts, so that the take-up mechanism and the film roll it holds are no longer located directly above the film winding mechanism 5, but are offset from the film winding mechanism 5 in the first direction W, making it convenient for the take-up mechanism 6 to move to a suitable unwinding position to release the film roll.

[0162] In this embodiment, the unwinding position suitable for releasing the membrane roll is located directly above the collector 9. For example... Figures 1-3 As shown, in this embodiment, the collecting component 9 is located on the side of the frame 1 away from the conveying device 20, and its top is open to facilitate the falling of the membrane roll, thereby achieving the purpose of membrane roll collection.

[0163] In the first direction W, when the take-up telescopic drive cylinder 641 retracts to its position, the first clamping member 61 and the second clamping member 62 of the take-up mechanism 6 still face the conveying device 20. To change the orientation of the first clamping member 61 and the second clamping member 62 towards the collecting member 9, so that they can easily deposit the film roll into the collecting member 9, as follows... Figure 14 and Figure 15As shown, in this embodiment, the film removal device 10 further includes a rotary drive mechanism 65. The rotary drive mechanism 65 is disposed on the base 69 and includes a rotary drive cylinder 651, a rotating shaft 652, and a slewing bearing 653. The rotating shaft 652 extends vertically and is rotatably connected to the base 69 via the slewing bearing 653. The rotary drive cylinder 651 extends along a first direction W and is drivenly connected to the take-up mechanism 6 to drive the take-up mechanism 6 to rotate around the rotating shaft 652, allowing the take-up mechanism 6 to rotate in a horizontal plane, thereby rotating it from a position facing the conveying device 20 to a position facing the collecting member 9.

[0164] After the take-up mechanism 6 rotates to the position where the first clamping member 61 and the second clamping member 62 face the collector 9, the take-up telescopic drive cylinder 641 can extend again, so that the first clamping member 61 and the second clamping member 62 move along the first direction W to the position where the film roll is directly above the collector 9. Then the second swing drive mechanism 632 is activated, driving the second clamping member 62 to swing downward and release the film roll. Thus, the film roll can fall into the collector 9 under the action of gravity and be collected by the collector 9.

[0165] As can be seen, in this embodiment, the take-up mechanism 6 can smoothly complete the take-up and unwinding process by moving along the first direction W, moving up and down in the direction H, and rotating around the vertical axis.

[0166] To prevent the film roll from falling off during the operation of the take-up mechanism 6, such as Figure 14 As shown, in this embodiment, the base 69 is also provided with a third presence detection device 66, which includes a third photoelectric sensor 661. Specifically, the third photoelectric sensor 661 is a diffuse reflection photoelectric sensor, which detects whether the film roll is located on the winding mechanism 6 by emitting light to the film roll, so as to prevent the film roll from falling off during the operation of the winding mechanism 6.

[0167] At the same time, such as Figure 14 and Figure 15 As shown, in this embodiment, the base 69 is also provided with a cable guide tube 67 and a cable reel drag chain 68, which are used for the cable to pass through and the cable to be dragged.

[0168] In this embodiment, each drive cylinder (e.g., film-breaking telescopic drive cylinder 321, film-removing telescopic drive cylinder 421, first swing drive mechanism 631, second swing drive mechanism 632, roll-taking telescopic drive cylinder 641, and rotation drive cylinder 651) is a pneumatic cylinder. Figure 1As shown, to control the orderly operation of these cylinders, in this embodiment, the membrane removal device 10 also includes a pneumatic valve island 82 and a pneumatic triplet 81. All cylinders are connected to the air source through the pneumatic valve island 82 and the pneumatic triplet 81, which are mounted on the frame 1. The pneumatic valve island 82 is equipped with a solenoid valve to control the opening and closing of each air path. The pneumatic triplet 81 connects the pneumatic valve island 82 to the air source and serves to regulate pressure, filter, and lubricate. Furthermore, in this embodiment, a pressure gauge 83 is also provided on the frame 1 for air pressure regulation.

[0169] With the structural form of this embodiment, the film removal device 10 can adapt to the removal of packaging films 40 of various specifications and in different positions, and can wrap and collect the packaging films 40, saving space.

[0170] Before the stack 30 moves into position on the conveyor 20, the lifting component is at a high position. After the stack 30 is in position, the lifting component descends. During the descent, the first detection element 21 detects the stack height. After detecting the stack height, the second detection element 22 detects the position of the packaging film according to the preset packaging film range to determine the accurate position of the packaging film. After the position of the packaging film 40 is determined, the film suction device 411 extends first to suck up the packaging film 40. Then, the heating wire 311 extends to prepare to melt the film. The film suction device 411 pulls back to pull the packaging film 40 off the stack 30, so that the packaging film 40 is melted by the heating wire 311. After that, the film suction device 411 continues to suck up the broken packaging film 40 and descends to the film winding mechanism 5. The broken packaging film 40 is placed on the film winding mechanism 5 and wound into a film roll by the film winding mechanism 5. After the winding is completed, the roll-up mechanism 6 takes the roll and puts it into the collection unit 9.

[0171] Specifically, the working process of the membrane removal equipment 10 is roughly as follows:

[0172] Initially, the lifting assembly, including the film cutting device 3, the film removing device 4, and the roll taking mechanism 6, is at a high position above the top of the stack 30. The stack 30 is then transported by the conveying equipment 20 and positioned.

[0173] Subsequently, the lifting assembly descends under the action of the lifting drive mechanism 15. During the descent, the height of the stack 30 is identified by the first detection element 21. After the height of the stack is identified, the second detection element 22 searches for the accurate film position according to the preset packaging film height range to determine the accurate height position of the packaging film 40.

[0174] After the height and position of the packaging film 40 are determined, the two film suction devices 411 extend simultaneously and adhere to the surface of the packaging film 40 on the stack 30 facing the film suction device 411 (on the stack 30). Figure 2 The middle part is the left side of the packaging film 40), in Figure 2 The packaging film 40 is picked up at positions A and B, and the packaging film 40 is pulled up a distance from the stack 30. Then the heating wire 311 extends and sticks tightly to the packaging film 40.

[0175] Then, the two film suction devices 411 retract one after the other, causing the pulled-up packaging film 40 to be held in place by the heating wire 311. Figure 2 The melt is broken at position C as shown. At the same time, the two film suction devices 411 continue to suck up the packaging film 40 and retract it. During the process, the pressure sensor 432 and the ultrasonic sensor 431 detect whether the packaging film 40 has fallen off.

[0176] Then, the lifting assembly carries the packaging film 40 downward. When the two film suction devices 411 move down to the height position of the film rolling mechanism 5, the two film suction devices 411 place the adsorbed packaging film 40 between the first roll bar 511 and the second roll bar 512 of the film rolling mechanism 5. During the process, the air blowing device 72 blows air onto the packaging film 40 to prevent the packaging film 40 from getting caught on the stack 30.

[0177] Subsequently, the first winding rod 511 and the second winding rod 512 of the film winding mechanism 5 rotate under the drive of the winding drive mechanism 52 to complete the winding of the packaging film 40 and form a film roll. During the process, the protective member 53 and the stop member 73 stop the packaging film 40 from the top and bottom sides to prevent the packaging film 40 from coming off during the wrapping process.

[0178] After the film roll is wound, the second photoelectric sensor 541 detects whether the film roll is on the film winding mechanism 5. When the film roll is on the film winding mechanism 5, the take-up mechanism 6 descends to a suitable take-up height, the take-up telescopic drive cylinder 641 extends into place, the first swing drive mechanism 631 drives the first clamping member 61 to swing downward to clamp the film roll, and then the take-up mechanism 6 moves upward to bring the film roll out of the winding mechanism 51, and the take-up telescopic drive cylinder 641 retracts.

[0179] When the take-up mechanism 6 moves up to the appropriate unwinding height, the rotary drive mechanism 65 drives the take-up mechanism 6 to rotate, the take-up telescopic drive cylinder 641 extends again, and the second swing drive mechanism 632 drives the second clamping member 62 to swing downward, so as to put the film roll into the collection member 9.

[0180] As can be seen, the film removal device 10 of this embodiment has a simple structure, rich functions, and is easy to use. It can efficiently and reliably remove packaging films 40 of various specifications and in uncertain positions, and wrap and collect the packaging films 40, saving space.

[0181] The above description is merely an exemplary embodiment of this application and is not intended to limit this application.
