Description

[Technical Field]

[0002] This utility model relates to the field of film roll packaging technology, and in particular to a gripping and handling device for use in film roll packaging lines. [Background Technology]

[0004] In the production and processing of film rolls, from raw material feeding and transfer between processing steps to final product packaging and storage, the rolls need to be efficiently and precisely moved between multiple workstations. Traditional roll handling methods have many drawbacks. Some simpler handling equipment uses a combination of manual assistance and simple mechanical structures, such as using forklifts with simple pallets or hooks to move the rolls. This method is not only inefficient, with long handling cycles, making it difficult to meet the pace requirements of modern high-speed production lines, but also prone to damage due to the uncontrollability of manual operation. Improper handling can easily lead to collisions and slippage of the rolls, affecting product quality and increasing the scrap rate. In addition, some existing relatively automated roll gripping and handling devices also have shortcomings. Common roll gripping and handling devices use clamping or gripping structures, which inevitably come into direct contact with the surface of the roll when gripping it. During long-term handling, especially for some film rolls with high surface quality requirements and fragile materials, direct contact can easily leave scratches, indentations or cause local deformation of the roll surface, seriously affecting the appearance quality and performance of the roll, reducing the yield rate of the product, and causing significant economic losses to the enterprise.

[0005] In summary, in order to overcome the aforementioned shortcomings of existing film roll handling methods and devices, there is an urgent need for a gripping and handling device that can efficiently and accurately handle film rolls and avoid damage to the roll surface, so as to meet the growing production needs and quality requirements of the modern film roll production and processing industry.

Detailed Implementation Methods

[0035] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0036] Please see Figures 1 to 9 This embodiment provides a gripping and handling device for a film roll packaging line, designed to efficiently and accurately handle film rolls while avoiding damage to the roll surface. It includes a sliding frame 1 slidably connected to a machine frame 5. Sliding blocks are provided on both sides of the sliding frame 1, which are connected to corresponding slide rails on both sides of the machine frame 5. A first drive mechanism 2 is connected to one side of the sliding frame 1 to drive its movement on the machine frame 5. Two opposing transverse moving components 3 are slidably connected to the sliding frame 1. Each of the two transverse moving components 3 is connected to a lifting gripping component 4. The lifting gripping component 4 can be connected to the core of the film roll to realize the turnover of the roll between different workstations.

[0037] Specifically, in this embodiment, sliders are provided on both sides of the sliding frame 1, which are connected to corresponding slide rails on both sides of the frame 5 to achieve movement on the packaging line. The first drive mechanism 2 is located on one side of the sliding frame 1 and is responsible for driving the sliding frame 1 to move on the frame 5. The first drive mechanism can be a motor, cylinder, hydraulic cylinder, or other device capable of providing power. Two opposing transverse moving components 3 are slidably connected to the sliding frame 1 and can move laterally. They can also adopt a slider-slide rail connection structure.

[0038] Each transverse component 3 is connected to a lifting gripping component 4. The lifting gripping component 4 can be a cylinder, hydraulic cylinder, motor-driven screw mechanism, or other device capable of lifting motion to adapt to workstations and rolls of material at different heights.

[0039] Furthermore, existing roll material gripping structures generally employ clamping or gripping types, which typically come into direct contact with the roll material surface, potentially causing damage. In contrast, the gripping and handling device of this embodiment features a lifting gripping component 4 that can precisely connect to the core of the film roll. For example, the gripping component can employ a pin-type structure adapted to the shape of the inner hole of the film roll core or a core connection structure with a special clamping mechanism. By precisely connecting to the core, direct contact with the film roll surface is avoided, effectively preventing damage to the roll material that may occur during handling due to friction or compression between the gripping structure and the roll material surface. This significantly improves the yield rate of film roll packaging production and reduces production costs caused by roll material damage.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the lifting and gripping assembly 4 includes a lifting mechanism 41 fixedly connected to the transverse assembly 3, the lifting mechanism 41 is connected to a gripping mechanism 42, the gripping mechanism 42 includes a gripping part 421 fixedly connected to the lifting mechanism 41, and the gripping part 421 is provided with a connecting end 4211 that can extend into the core of the roll material.

[0041] In this embodiment, through the precise connection between the connecting end 4211 and the roll core, the gripping mechanism 42 can provide accurate and stable gripping force, ensuring that the roll will not fall off or shift during transportation. Specifically, the connecting end 4211 on the gripping part 421 is shaped to match the inner diameter of the roll core. For example, for a roll core with a specific inner diameter, the connecting end 4211 can be a cylindrical protrusion slightly smaller than that inner diameter. When the lifting mechanism 41 drives the gripping part 421 to descend, the connecting end 4211 can smoothly extend into the roll core. In some other embodiments, the connecting end 4211 can also be a metal column structure with an elastic rubber layer. When inserted into the roll core, the rubber layer deforms moderately to provide sufficient friction and clamping force, ensuring that the roll is firmly gripped without damaging the roll core.

[0042] In actual handling of the roll material, the first drive mechanism 2 first operates, moving the sliding frame 1 above the area where the roll material is located. Then, the lateral movement component 3 adjusts its lateral position according to the roll material's location. Next, the lifting mechanism 41 is activated, causing the connecting end 4211 of the gripping part 421 to descend and extend into the roll material core, forming an insertion with the core and completing the gripping action. Afterward, through the reverse actions of each mechanism, the roll material is transported to the target workstation.

[0043] Furthermore, as a preferred embodiment of this solution and not a limitation, the lifting mechanism 41 includes a mounting base 411 fixedly connected to the lateral moving assembly 3, a gripping arm 412 connected below the mounting base 411, and a second drive mechanism 413 for realizing lifting is connected between the gripping arm 412 and the gripping mechanism 42.

[0044] In this embodiment, the lifting mechanism 41 includes a mounting base 411 fixedly connected to the traversing component 3. The mounting base 411 serves as the foundation of the lifting mechanism 41, providing stable connection and support for other components. A gripping arm 412 is connected below the mounting base 411. The gripping arm 412 is a key component for realizing the vertical movement of the gripping mechanism 42. Through its connection with the mounting base 411, it transmits the lifting motion to the gripping mechanism 42. A second drive mechanism 413 for realizing lifting is connected between the gripping arm 412 and the gripping mechanism 42. The second drive mechanism 413 is responsible for driving the vertical movement of the gripping mechanism 42. It can be a cylinder, hydraulic cylinder, motor-driven screw mechanism, or other devices capable of realizing lifting motion. It can precisely adjust the height position of the gripping mechanism 42 to adapt to the needs of handling roll materials at different heights, improving the device's adaptability to different specifications of roll materials, enhancing the device's versatility, reducing the strict requirements for the consistency of roll material placement height, and improving the flexibility and efficiency of roll material handling on the production line.

[0045] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the second drive mechanism 413 includes a lead screw 4131 arranged vertically along the gripping arm 412. The upper end of the lead screw 4131 passes through the mounting base 411 and is connected to a second reducer 4132. The second reducer 4132 is connected to a second servo motor 4133. A connecting block 4134 that can move vertically along the lead screw 4131 is sleeved on the lead screw 4131. A guide shaft 4135 is connected below the connecting block 4134. A linear bearing 4136 corresponding to the guide shaft 4135 is provided on one side of the lower part of the gripping arm 412. The gripping mechanism 42 is fixedly connected to the guide shaft 4135 through the linear bearing 4136.

[0046] Specifically, two guide shafts 4135 are connected below the connecting block 4134. Each guide shaft 4135 passes through its corresponding linear bearing 4136 and is fixedly connected to the gripping part of the gripping mechanism 42. In this embodiment, the second drive mechanism 413 employs a structure composed of a lead screw 4131, a second reducer 4132, and a second servo motor 4133, enabling precise lifting control. The high-precision control characteristics of the servo motor allow the lifting position of the gripping mechanism 42 to be accurate to a fraction of a millimeter. This is crucial for handling roll materials with varying height requirements, greatly improving the device's adaptability to changes in roll material height, reducing damage or handling failures caused by inaccurate gripping height, and improving production success rate and product quality.

[0047] The cooperation between the guide shaft 4135 and the linear bearing 4136 provides stable guidance for the lifting and lowering of the gripping mechanism 42. During high-speed lifting, this guiding structure effectively prevents the gripping mechanism 42 from swaying or deviating, ensuring the accuracy and stability of the gripping action. It avoids problems such as roll material falling or colliding caused by unstable gripping, further protecting the integrity of the roll material, reducing production costs, and improving production efficiency. At the same time, the stable guiding structure also helps extend the service life of various components of the device, reducing component wear and failures caused by vibration and impact, and lowering equipment maintenance costs.

[0048] Furthermore, as a preferred embodiment of this solution and not a limitation, the gripping arm 412 is provided with a strip-shaped hole 4121, and a first limit sensor 4122 passing through the strip-shaped hole 4121 is provided on one side of the connecting block 4134. A first proximity switch 4123 cooperating with the first limit sensor 4122 is provided along the upper and lower edges of the strip-shaped hole 4121, respectively, to limit the lifting range of the gripping mechanism 42.

[0049] In this embodiment, the combination of the first limit sensor 4122 and the first proximity switch 4123 precisely limits the lifting range of the gripping mechanism 42. This not only effectively prevents equipment damage caused by overtravel of the gripping mechanism 42, extending the service life of the equipment and reducing equipment maintenance costs, but also ensures the safety of the entire gripping and handling process, avoids safety accidents caused by equipment failure, and provides a safe working environment for operators.

[0050] Precise control of the lifting range also helps improve the accuracy and stability of roll material handling. By preventing the gripping mechanism 42 from stopping or moving in unexpected positions, the stability of the roll material's posture during gripping, handling, and placement is ensured, reducing surface scratches, deformation, and other damage that may occur due to positional deviations, and improving the yield rate of film roll packaging production.

[0051] In this embodiment, the first protective cover 4124 and the second protective cover 4125 effectively protect the transmission components inside the lifting and gripping assembly 4, greatly reducing component failures caused by external factors such as dust and impurities, significantly improving the reliability and stability of the equipment, reducing downtime and maintenance time and costs due to equipment failures, and improving production efficiency. Furthermore, the heat dissipation holes on the second protective cover 4125 provide good heat dissipation conditions for the second servo motor 4133 and other components, avoiding performance degradation and shortened lifespan caused by motor overheating, ensuring the motor can work continuously and stably, thereby guaranteeing the accuracy and timeliness of the lifting action of the gripping mechanism 42, further improving the working performance and stability of the entire gripping and handling device, and contributing to the long-term stable operation of the film roll packaging production line and the improvement of production efficiency.

[0052] Furthermore, as a preferred embodiment of this solution and not a limitation, the lateral movement component 3 includes a sliding mounting plate 31 slidably connected to the sliding frame 1. The bottom of the sliding mounting plate 31 is provided with a slider that cooperates with a corresponding slide rail on the sliding frame 1. The sliding mounting plate 31 is connected to the lifting and gripping component 4. The sliding mounting plate 31 is provided with a third drive mechanism 32 to enable the lifting and gripping component 4 to move laterally relative to the sliding frame 1.

[0053] In this embodiment, the sliding connection between the sliding mounting plate 31 of the transverse component 3 and the sliding frame 1, along with the precise control of the third drive mechanism 32, enables the lifting gripping component 4 to achieve high-precision position adjustment in the horizontal direction. This not only adapts to film rolls placed in different lateral positions, improving the versatility of the device, but also ensures precise docking with other workstation equipment when gripping and placing the rolls, reducing roll handling errors caused by positional deviations and improving production efficiency and product quality.

[0054] Specifically, the third drive mechanism 32 includes a third reducer 321 mounted on the sliding mounting plate 31. The upper end of the third reducer 321 is connected to a third servo motor 322 and the lower end is connected to a third gear 323 passing through the sliding mounting plate 31. The sliding frame 1 is provided with a corresponding rack that cooperates with the third gear 323 to realize the lateral movement of the lifting and gripping component 4 relative to the sliding frame 1. A second proximity switch 311 is mounted on one side of the sliding mounting plate 31. The sliding frame 1 is equipped with a plurality of second limit sensors 13 that can cooperate with the second proximity switch 311 to limit the lateral movement range of the lateral movement component 3.

[0055] In this embodiment, the third drive mechanism 32 employs a combination of a third servo motor 322, a third reducer 321, and a third gear 323 with a rack and pinion to achieve high-precision, high-speed movement of the lifting gripping assembly 4 in the lateral direction. This precise control capability enables the device to quickly adapt to the handling needs of rolls of different widths, improving the device's working efficiency and versatility. Simultaneously, the high-precision lateral positioning effectively reduces the risks of collisions and slippage caused by positional deviations during the gripping and placement of rolls, ensuring the integrity of the rolls and the accuracy of handling, thereby improving the yield rate of film roll packaging production.

[0056] Furthermore, as a preferred embodiment of this solution and not a limitation, the first drive mechanism 2 includes a first reducer 21 fixedly connected to one side of the sliding frame 1. The upper end of the first reducer 21 is connected to a first servo motor 22, and drive shafts 23 are respectively provided on both sides. A first gear 24 is provided on one side of the drive shaft 23, which cooperates with the rack on the frame 5 to make the sliding frame 1 slide relative to the frame, thereby realizing the turnover of the film roll at different work stations. A corresponding drive shaft protective cover 25 fixedly connected to one side of the sliding frame 1 is also provided next to the drive shaft 23.

[0057] In this embodiment, the first drive mechanism 2 employs a first servo motor 22, a first reducer 21, a first gear 24, and a rack and pinion mechanism on the frame, and is equipped with a drive shaft protective cover 25, enabling precise and stable movement of the sliding frame 1 on the frame. Precise movement facilitates rapid positioning of the roll material, improving handling efficiency and reducing potential damage to the roll material or surrounding equipment caused by inaccurate positioning, thus ensuring the safety and stability of the production process. The drive shaft protective cover 25 extends the service life of the drive components, reduces equipment maintenance costs, and ensures the long-term reliable operation of the entire device.

[0058] Furthermore, as a preferred embodiment of this solution and not a limitation, the sliding frame 1 is provided with a matching third protective cover 11, the third protective cover 11 is provided with a slot through which the third servo motor 322 can pass, and the third protective cover 11 is also provided with a heat dissipation cover 12 covering the third servo motor 322.

[0059] In this embodiment, the third protective cover 11 provides comprehensive protection for the transverse moving assembly 3 inside the sliding frame 1, effectively blocking external impurities and reducing the risk of component wear, jamming, and other malfunctions caused by impurities entering the device. This improves the operational reliability and stability of the transverse moving assembly 3 and reduces the frequency and cost of equipment maintenance. Simultaneously, the heat dissipation cover 12's cooling effect on the third servo motor 322 ensures stable motor performance during prolonged operation, preventing malfunctions caused by motor overheating, extending motor lifespan, and further guaranteeing the continuous and efficient operation of the entire gripping and handling device, thereby improving production efficiency.

[0060] Furthermore, as a preferred embodiment of this solution and not a limitation, the sliding frame 1 is provided with buffer devices 14 on both sides to provide pressure and shock absorption for the sliding mounting plate 31. The buffer device 114 includes an anti-collision base fixedly connected to the sliding mounting plate 31, and an anti-collision pad is provided on the anti-collision base to provide pressure and shock absorption for the sliding mounting plate 31.

[0061] In this embodiment, buffer devices 14 are disposed on both sides of the sliding frame 1 to provide pressure and shock absorption for the sliding mounting plate 31, reducing the impact and vibration of the sliding mounting plate 31 during movement. The buffer devices 14 reduce the impact and vibration of the sliding mounting plate 31 during movement, protecting the sliding mounting plate 31 and its connected lifting and gripping assembly 4, and extending the service life of the equipment. Simultaneously, by reducing impact and vibration, the stability and reliability of the equipment can be improved, ensuring that the equipment operates within its normal working range. Furthermore, the buffer devices 14 can also reduce the noise generated during equipment operation, improving the comfort of the working environment.

[0062] Working principle of this utility model:

[0063] This embodiment provides a gripping and handling device for use in a film roll packaging line. In actual packaging production, when the handling operation is started, the first servo motor starts running under the drive of a control signal. The power is transmitted to the drive shaft through the first reducer. The first gear on the drive shaft meshes with the rack on the frame, thereby driving the sliding frame to move on the frame. During this process, the drive shaft protective cover effectively prevents external impurities from interfering with the drive shaft and the first gear, ensuring the stability and reliability of the transmission.

[0064] Subsequently, the lateral movement assembly begins operation. Upon receiving the command, the third servo motor drives the third gear to rotate via the third reducer, causing the sliding mounting plate to move laterally on the sliding frame. At this point, the third protective cover on the sliding frame plays a crucial role. It fits snugly against the frame, providing protection for the internal transmission components and preventing dust, oil, and other impurities from entering and affecting the normal operation of the lateral movement assembly. The slots on the cover allow the third servo motor to pass through, ensuring its proper installation and connection while also limiting the entry of other foreign objects. The heat sink covering the third servo motor effectively dissipates the heat generated during operation, keeping the motor temperature within the normal operating range and ensuring the stable operation of the lateral movement assembly.

[0065] Next, the second servo motor of the lifting and gripping assembly starts, driving the lead screw to rotate, causing the connecting block to move vertically along the lead screw. The guide shaft is smoothly guided within the linear bearing, and the gripping mechanism descends accordingly. The connecting end of the gripping part precisely extends into the core of the film roll and firmly grips it, ensuring that the film roll will not fall off during transportation. In addition, this gripping structure can also avoid damage to the surface of the film roll.

[0066] Finally, through the coordinated efforts of all components, the roll material is transported to designated packaging, inspection, or storage stations. For example, when transporting it to the packaging station, the first drive mechanism, the traversing component, and the lifting and gripping component move in sequence with precision, placing the roll material smoothly on the operating platform of the packaging station. The entire process is efficient, accurate, and stable.

[0067] The above are implementation methods provided in conjunction with specific content, and it is not intended that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
