Abstract
Description
Technical Field
[0001] This utility model relates to the field of film roll wrapping equipment, specifically to an automatic adjustable film roll gripping device for film roll wrapping. Background Technology
[0002] Rolled film, or film roll, is cylindrical. After winding, the film roll needs to be wrapped with a protective film on its outer surface. However, current film roll handling devices only have the ability to grasp and transport, and cannot perform film roll wrapping. For example, Chinese Patent Publication No. CN113845017A describes an invention entitled "A Gripping Device for Lifting Film Rolls." Therefore, current film roll wrapping operations generally involve laying the packaging film on a wrapping platform; then, using a film roll handling device, transporting the film roll to be wrapped onto the platform; and finally, manually rolling the film roll to wrap the packaging film from the platform onto its outer surface. Manual wrapping not only affects the wrapping efficiency but also easily leads to wrapping skew and looseness, affecting the wrapping quality. Utility Model Content
[0003] The purpose of this invention is to provide an automatic adjustable film roll gripping device for film roll wrapping that can not only grip and transport film rolls, but also cooperate with a wrapping platform to wrap film rolls, thereby improving the wrapping efficiency and wrapping quality.
[0004] The technical solution of this utility model is:
[0005] An automatic adjustable film roll gripping device for film roll wrapping includes:
[0006] Rack, including top rack;
[0007] The longitudinal movement device includes a longitudinal movement slide mounted on a top frame and a longitudinal movement actuator that drives the longitudinal movement slide to move.
[0008] The transverse movement device includes a transverse slide that is slidably mounted on a longitudinal slide and a transverse movement actuator that drives the transverse slide to move.
[0009] A lifting device, including a lifting seat and a lifting mechanism disposed on a transverse slide to drive the lifting seat to rise and fall;
[0010] The gripping mechanism includes two grippers slidably mounted on a lifting base and a gripper drive mechanism that drives the two grippers to approach or separate from each other. A film roll shaft is rotatably mounted on each gripper. The specific operation of an automatic adjustable film roll gripping device for film roll wrapping according to this solution is as follows:
[0011] First, lay the packaging film on the wrapping platform (the edges of both ends of the wrapping film are coated with glue).
[0012] The position of the gripping mechanism is adjusted by the longitudinal movement device, the transverse movement device and the lifting device so that the film roll to be gripped is located between the two grippers on the lifting seat; then the gripper drive mechanism drives the two grippers to move closer to each other so that the film roll shafts on the two grippers are inserted into the center holes at both ends of the film roll.
[0013] Second, the lifting device drives the film roll between the gripping mechanism and the two grippers to rise; then the longitudinal and transverse movement devices move the film roll to a designated position above the wrapping platform.
[0014] Next, the lifting device lowers the film roll, causing it to contact the adhesive-coated edge of the packaging film on the wrapping platform.
[0015] Next, the longitudinal movement device drives the transverse movement device, lifting device, gripping mechanism, and film roll to move horizontally. Since the film roll shaft is rotatable, the film roll supported on the two grippers can rotate with it. Therefore, during the film roll's horizontal movement, it can move and rotate simultaneously, allowing the packaging film to wrap around the outer circumference of the film roll, thus achieving the wrapping operation for the cylindrical film roll. Therefore, the automatic adjustable film roll gripping device in this solution can not only grip and transport film rolls but also work with the wrapping platform to wrap the film rolls, thereby improving wrapping efficiency and quality. It effectively solves the problems of manual wrapping, which not only affects wrapping efficiency but also easily leads to wrapping skew and looseness, affecting the wrapping quality.
[0016] Third, the lifting device drives the film roll between the gripping mechanism and the two grippers to rise; then the longitudinal and transverse moving devices move the film roll to a designated position above the wrapping platform.
[0017] Preferably, the grippers are equipped with fixed shafts, which are coaxially distributed on both grippers. The membrane roll has coaxially distributed shaft holes, and the fixed shafts are inserted into the corresponding shaft holes of the membrane roll. The fixed shafts and the membrane roll are connected by bearings. This ensures that the membrane roll can rotate stably and reliably around the fixed shafts.
[0018] Preferably, the membrane roll spool is provided with an outwardly extending membrane roll stop. In this way, when the gripper drive mechanism drives the two grippers to move closer to each other, the membrane roll spools on the two grippers are inserted into the center holes at both ends of the membrane roll until the membrane roll stop is against the end of the membrane roll, thereby ensuring that the membrane roll is stably and reliably gripped between the two grippers, and without affecting the rotation of the membrane roll with the membrane roll spool.
[0019] Preferably, the sliding direction of the gripper is parallel to the sliding direction of the transverse slide, and the film roll is parallel to the sliding direction of the gripper.
[0020] Preferably, the lifting seat is equipped with a guide rail, and the gripper includes a gripper slide that slides along the guide rail and a vertical gripping arm disposed on the gripper slide. The vertical gripping arm extends downward from the gripper slide, and the membrane roll is disposed on the vertical gripping arm, with the membrane roll parallel to the guide rail. This facilitates the manufacture of the gripper; furthermore, in the actual manufacturing process, the use of membrane rolls with different outer diameters can be adapted by changing the vertical gripping arms of different lengths.
[0021] Preferably, the lifting seat is provided with a guide rail, and the gripper slides along the guide rail. The gripper driving mechanism includes:
[0022] Two first lead screw mechanisms correspond one-to-one with the grippers. The lead screw of the first lead screw mechanism is rotatably mounted on the lifting seat and parallel to the guide rail. The nut of the first lead screw mechanism is connected to the corresponding gripper.
[0023] The first dual-output-shaft motor, located between the two first lead screw mechanisms, includes two output shafts. The first output shaft is connected to the lead screw of one of the first lead screw mechanisms, and the other output shaft is connected to the lead screw of the other first lead screw mechanism. Thus, a single first dual-output-shaft motor can synchronously drive the two grippers to approach or separate, which helps reduce manufacturing costs and simplifies the equipment structure.
[0024] Preferably, the lifting seat is provided with two vertical guide columns, which are slidably connected to the horizontal sliding seat in a height-adjustable manner.
[0025] The lifting mechanism includes:
[0026] Two vertical racks are installed on the vertical guide posts, one for each of them;
[0027] The lifting gears, which correspond one-to-one with the vertical racks, are rotatably mounted on the transverse slide block, and the lifting gears mesh with the corresponding vertical racks;
[0028] The dual-output shaft lifting motor includes two output shafts. One output shaft is connected to one lifting gear, and the other output shaft is connected to the other lifting gear. In this way, a single dual-output shaft lifting motor can synchronously drive the two lifting gears to rotate, thereby achieving the lifting and lowering of the lifting platform and ensuring its stability.
[0029] Preferably, the transverse slide has two L-shaped vertical supports, each consisting of two vertical plates. Each vertical support corresponds to a vertical guide post, which has a rectangular cross-section and is located between the two vertical plates of the corresponding vertical support. Both vertical plates of the vertical support have vertical tracks, allowing the guide posts to slide up and down along these tracks. This not only further improves the lifting stability of the slide but also facilitates the installation of the vertical rack.
[0030] Preferably, the lateral movement device further includes a transverse track disposed on the longitudinal movement slide, the lateral movement slide sliding along the transverse track, and the lateral movement actuator includes:
[0031] A transverse rack is mounted on the longitudinal slide block and is parallel to the transverse track;
[0032] The transverse gear is rotatably mounted on the transverse slide and meshes with the transverse rack;
[0033] A transverse motor, mounted on the transverse slide, drives the transverse gear to rotate. This ensures that the transverse actuator smoothly drives the transverse slide to move.
[0034] Preferably, the longitudinal movement device further includes a longitudinal rail mounted on the top frame, and the longitudinal movement slide slides along the longitudinal rail. The longitudinal movement actuator includes:
[0035] Two parallel longitudinal racks are mounted on the top frame;
[0036] The longitudinal shift gears, which correspond one-to-one with the longitudinal racks, are rotatably mounted on the longitudinal slide block, and the longitudinal shift gears mesh with the corresponding longitudinal racks;
[0037] The dual-output-shaft longitudinal traverse motor includes two output shafts. One output shaft is connected to one longitudinal traverse gear via a connecting rod, and the other output shaft is connected to the other longitudinal traverse gear via a connecting rod. In this way, a single dual-output-shaft longitudinal traverse motor can synchronously drive the rotation of both longitudinal traverse gears to achieve the translation of the longitudinal slide and ensure the translational stability of the longitudinal slide.
[0038] The beneficial effects of this invention are: it can not only grasp and transport film rolls; but also, during the process of driving the film roll to move horizontally, the automatic adjusting film roll grasping device can make the film roll rotate while moving horizontally, so that it can cooperate with the film wrapping platform to achieve film wrapping, thereby improving the film roll wrapping efficiency and wrapping quality; it effectively solves the problem that manual wrapping not only affects the film roll wrapping efficiency, but also easily causes wrapping skew and looseness, affecting the film roll wrapping quality.

[0049] Specific Implementation Example 1, such as Figure 1 , Figure 2 , Figure 3 As shown, an automatic adjustable film roll gripping device for film roll wrapping includes a frame 1, a longitudinal movement device 2, a transverse movement device 3, a lifting device 4, and a gripping mechanism 5.
[0050] The rack 1 includes the top rack 1.1.
[0051] The longitudinal movement device 2 includes a longitudinal movement slide 2.2 slidably mounted on the top frame 1.1 and a longitudinal movement actuator 2.3 for driving the longitudinal movement slide 2.2 to move. Specifically, the longitudinal movement device 2 also includes a longitudinal track 2.1 mounted on the top frame 1.1, and the longitudinal movement slide 2.2 slides along the longitudinal track 2.1.
[0052] The transverse movement device 3 includes a transverse slide 3.1 slidably mounted on the longitudinal slide 2.2 and a transverse movement actuator 3.3 for driving the transverse slide 3.1 to move. Specifically, the transverse movement device 3 also includes a transverse track 3.2 mounted on the longitudinal slide 2.2, along which the transverse slide 3.1 slides. The transverse track 3.2 is perpendicular to the longitudinal track 2.1. The transverse track 3.2 and the longitudinal track 2.1 are horizontally distributed.
[0053] The lifting device 4 includes a lifting seat 4.1 and a lifting mechanism 4.2 mounted on a transverse slide 3.1 to drive the lifting seat 4.1 to rise and fall.
[0054] The gripping mechanism 5 includes two grippers 5.1 slidably mounted on the lifting base 4.1 and a gripper drive mechanism 5.3 that drives the two grippers 5.1 to approach or separate from each other. Specifically, the lifting base 4.1 is provided with a guide rail. The grippers slide along the guide rail. Each gripper is rotatably mounted with a membrane roll 5.2. The membrane rolls 5.2 on the two grippers are coaxially distributed.
[0055] The specific operation of the automatic adjustable film roll gripping device for film roll wrapping in this embodiment is as follows:
[0056] First, lay the packaging film on the wrapping platform (the edges of both ends of the wrapping film are coated with glue).
[0057] The position of the gripping mechanism 5 is adjusted by the longitudinal movement device 2, the transverse movement device 3 and the lifting device 4 so that the membrane roll 6 to be gripped is located between the two grippers on the lifting seat 4.1; then the gripper driving mechanism 5.3 drives the two grippers to move closer to each other so that the membrane roll shaft 5.2 on the two grippers is inserted into the center holes at both ends of the membrane roll 6.
[0058] Second, the lifting device 4 drives the gripping mechanism 5 and the two grippers to rise; then the longitudinal movement device 2 and the transverse movement device 3 move the film roll to a designated position above the wrapping platform.
[0059] Next, the lifting device 4 lowers the film roll, so that the film roll contacts the edge of the packaging film coated with adhesive on the wrapping platform;
[0060] Next, the longitudinal movement device 2 drives the transverse movement device 3, the lifting device 4, and the gripping mechanism 5 to translate the film roll. Since the film roll shaft 5.2 is rotatable, the film roll supported on the two grippers on the film roll shaft 5.2 can rotate with the film roll shaft 5.2. Therefore, during the translation of the film roll, the film roll can move and rotate at the same time, so that the packaging film is wrapped around the outer circumference of the film roll, thereby realizing the wrapping operation of the cylindrical film roll. Therefore, the automatic adjustable film roll gripping device for film roll wrapping in this embodiment can not only grip and transport the film roll, but also cooperate with the wrapping platform to realize the wrapping of the film roll, thereby improving the film roll wrapping efficiency and wrapping quality; effectively solving the problem that manual wrapping not only affects the wrapping efficiency of the film roll, but also easily causes wrapping deviation and looseness, affecting the wrapping quality of the film roll.
[0061] Third, the lifting device 4 drives the gripping mechanism 5 and the two grippers to rise; then the longitudinal movement device 2 and the transverse movement device 3 move the film roll to a designated position above the wrapping platform.

[0063] The frame 1 includes a top frame 1.1. Specifically, the frame 1 includes several supporting columns. The top frame 1.1 is located on top of each supporting column. The space below the top frame 1.1 is used to arrange the coating platform.
[0064] The longitudinal movement device 2 includes a longitudinal movement slide 2.2 slidably mounted on the top frame 1.1 and a longitudinal movement actuator 2.3 for driving the longitudinal movement slide 2.2 to move. Specifically, the longitudinal movement device 2 also includes a longitudinal track 2.1 mounted on the top frame 1.1, and the longitudinal movement slide 2.2 slides along the longitudinal track 2.1.
[0065] The transverse movement device 3 includes a transverse slide 3.1 slidably mounted on the longitudinal slide 2.2 and a transverse movement actuator 3.3 for driving the transverse slide 3.1 to move. Specifically, the transverse movement device 3 also includes a transverse track 3.2 mounted on the longitudinal slide 2.2, along which the transverse slide 3.1 slides. The transverse track 3.2 is perpendicular to the longitudinal track 2.1. The transverse track 3.2 and the longitudinal track 2.1 are horizontally distributed.
[0066] The lifting device 4 includes a lifting seat 4.1 and a lifting mechanism 4.2 mounted on a transverse slide 3.1 to drive the lifting seat 4.1 to rise and fall. Specifically, the lifting seat 4.1 is provided with two vertical guide columns 4.3, which are slidably connected to the transverse slide 3.1.
[0067] The gripping mechanism 5 includes two grippers 5.1 slidably mounted on the lifting seat 4.1 and a gripper drive mechanism 5.3 that drives the two grippers 5.1 to move closer together or separate. Specifically, the lifting seat 4.1 is provided with a guide rail. The guide rail is parallel to the transverse track 3.2. The grippers slide along the guide rail. The sliding direction of the grippers is parallel to the sliding direction of the transverse slide 3.1. Each gripper is rotatably equipped with a membrane roll 5.2. The membrane rolls 5.2 on the two grippers are coaxially distributed. The membrane rolls 5.2 are parallel to the sliding direction of the grippers.
[0068] The specific operation of the automatic adjustable film roll gripping device for film roll wrapping in this embodiment is as follows:
[0069] First, lay the packaging film on the wrapping platform (the edges of both ends of the wrapping film are coated with glue).
[0070] The position of the gripping mechanism 5 is adjusted by the longitudinal movement device 2, the transverse movement device 3 and the lifting device 4 so that the membrane roll 6 to be gripped is located between the two grippers on the lifting seat 4.1; then the gripper driving mechanism 5.3 drives the two grippers to move closer to each other so that the membrane roll shaft 5.2 on the two grippers is inserted into the center holes at both ends of the membrane roll 6.
[0071] Second, the lifting device 4 drives the gripping mechanism 5 and the two grippers to rise; then the longitudinal movement device 2 and the transverse movement device 3 move the film roll to a designated position above the wrapping platform.
[0072] Next, the lifting device 4 lowers the film roll, so that the film roll contacts the edge of the packaging film coated with adhesive on the wrapping platform;
[0073] Next, the longitudinal movement device 2 drives the transverse movement device 3, the lifting device 4, and the gripping mechanism 5 to translate the film roll. Since the film roll shaft 5.2 is rotatable, the film roll supported on the two grippers on the film roll shaft 5.2 can rotate with the film roll shaft 5.2. Therefore, during the translation of the film roll, the film roll can move and rotate at the same time, so that the packaging film is wrapped around the outer circumference of the film roll, thereby realizing the wrapping operation of the cylindrical film roll. Therefore, the automatic adjustable film roll gripping device for film roll wrapping in this embodiment can not only grip and transport the film roll, but also cooperate with the wrapping platform to realize the wrapping of the film roll, thereby improving the film roll wrapping efficiency and wrapping quality; effectively solving the problem that manual wrapping not only affects the wrapping efficiency of the film roll, but also easily causes wrapping deviation and looseness, affecting the wrapping quality of the film roll.
[0074] Third, the lifting device 4 drives the gripping mechanism 5 and the two grippers to rise; then the longitudinal movement device 2 and the transverse movement device 3 move the film roll to a designated position above the wrapping platform.
[0075] Furthermore, such as Figure 1 , Figure 2 As shown, the longitudinal traverse actuator 2.3 includes a dual-output-shaft longitudinal traverse motor 2.33, two parallel longitudinal racks 2.31, and longitudinal traverse gears 2.32 corresponding to the longitudinal racks 2.31. The longitudinal racks 2.31 are parallel to the longitudinal track 2.1. The longitudinal racks 2.31 are mounted on the top frame 1.1. The longitudinal gears 2.32 are rotatably mounted on the longitudinal slide 2.2 and mesh with the corresponding longitudinal racks 2.31. The dual-output-shaft longitudinal traverse motor 2.33 is mounted on the longitudinal slide 2.2. The dual-output-shaft longitudinal traverse motor 2.33 includes two output shafts, which are coaxial. One output shaft is connected to one of the longitudinal gears 2.32 via a connecting rod 2.34, and the other output shaft is connected to the other longitudinal gear 2.32 via a connecting rod 2.34. In this way, a single dual-output shaft longitudinal motor 2.33 can synchronously drive the two longitudinal gears 2.32 to rotate, thereby realizing the translation of the longitudinal slide 2.2 and ensuring the translational stability of the longitudinal slide 2.2.
[0076] It should be noted that the longitudinal actuator 2.3 can also use other drive mechanisms available on the market, such as linear modules or electric cylinders.
[0077] Furthermore, such as Figure 1 , Figure 2 , Figure 3 As shown, the transverse actuator 3.3 includes a transverse rack 3.31, a transverse gear, and a transverse motor 3.32. The transverse rack 3.31 is mounted on the longitudinal slide 2.2 and is parallel to the transverse track 3.2. The transverse gear is rotatably mounted on the transverse slide 3.1 and meshes with the transverse rack 3.31. The transverse motor 3.32 is mounted on the transverse slide 3.1 and drives the transverse gear to rotate. This ensures that the transverse actuator 3.3 smoothly drives the transverse slide 3.1 to move.
[0078] It should be noted that the transverse actuator 3.3 can also use other drive mechanisms available on the market, such as linear modules or electric cylinders.
[0079] Furthermore, such as Figure 1 , Figure 2 , Figure 3 As shown, the lifting mechanism 4.2 includes a dual-output shaft lifting motor 4.22, two vertical racks 4.21, and lifting gears 4.23 corresponding to the vertical racks 4.21. The two vertical racks 4.21 are mounted on vertical guide posts 4.3. The lifting gears 4.23 are rotatably mounted on the transverse slide block 3.1 and mesh with their corresponding vertical racks 4.21. The dual-output shaft lifting motor 4.22 is mounted on the transverse slide block 3.1. The dual-output shaft lifting motor 4.22 includes two output shafts, which are coaxially distributed. One output shaft is connected to one of the lifting gears 4.23, and the other output shaft is connected to the other lifting gear 4.23. Thus, a single dual-output shaft lifting motor 4.22 can synchronously drive the two lifting gears 4.23 to rotate, achieving the lifting and lowering of the lifting seat 4.1 and ensuring the stability of the lifting seat 4.1.
[0080] Furthermore, such as Figure 2 , Figure 3 As shown, the transverse slide 3.1 is equipped with two L-shaped vertical supports 3.4, each consisting of two vertical plates. Each vertical support 3.4 corresponds to a vertical guide post 4.3. The vertical guide post 4.3 has a rectangular cross-section and is located between the two vertical plates of the corresponding vertical support 3.4. Vertical rails are provided on both vertical plates of the vertical support 3.4. The vertical guide post 4.3 slides up and down along the vertical rails of the vertical support 3.4. This not only further improves the lifting stability of the lifting seat 4.1 but also facilitates the installation of the vertical rack 4.21.
[0081] Furthermore, such as Figure 1 , Figure 3As shown, the gripper 5.1 includes a gripper slide 5.11 that slides along the guide rail and a vertical gripping arm 5.12 mounted on the gripper slide 5.11. The vertical gripping arm 5.12 extends downward from the gripper slide 5.11. A membrane roll 5.2 is mounted on the vertical gripping arm 5.12. The membrane roll 5.2 is parallel to the guide rail. This facilitates the manufacture of the gripper; furthermore, in actual manufacturing, different lengths of the vertical gripping arm 5.12 can be used to accommodate membrane rolls with different outer diameters.
[0082] Furthermore, such as Figure 3 As shown, the gripper drive mechanism 5.3 includes a first dual-output shaft motor 5.32 and two first lead screw mechanisms 5.31. Each first lead screw mechanism 5.31 corresponds to one gripper. The lead screw of each first lead screw mechanism 5.31 is rotatably mounted on the lifting seat 4.1 and parallel to the guide rail. The nut of each first lead screw mechanism 5.31 is connected to the corresponding gripper. The first dual-output shaft motor 5.32 is located between the two first lead screw mechanisms 5.31. The first dual-output shaft motor 5.32 includes two output shafts, which are coaxial. The first output shaft is connected to the lead screw of one of the first lead screw mechanisms 5.31, and the other output shaft is connected to the lead screw of the other first lead screw mechanism 5.31. Thus, only one first dual-output shaft motor 5.32 is needed to synchronously drive the two grippers to move closer or further apart, which helps reduce manufacturing costs and simplify the equipment structure.
[0083] It should be noted that the gripper drive mechanism 5.3 can also use other drive mechanisms available on the market, such as linear modules or electric cylinders.
[0084] Furthermore, such as Figure 3 As shown, a fixed shaft 5.4 is provided on the gripper 5.1. The fixed shafts 5.4 on the two grippers are coaxially distributed. The membrane roll spool 5.2 has coaxially distributed shaft holes. The fixed shaft 5.4 is inserted into the corresponding shaft hole of the membrane roll spool 5.2, and the fixed shaft 5.4 and the membrane roll spool 5.2 are connected by bearings. In this way, the membrane roll spool 5.2 can rotate stably and reliably around the fixed shaft 5.4.
[0085] Furthermore, such as Figure 3 As shown, the membrane roll spool 5.2 is provided with an outwardly extending membrane roll stop 5.21. Thus, when the gripper drive mechanism 5.3 drives the two grippers to move closer to each other, the membrane roll spool 5.2 on the two grippers is inserted into the center holes at both ends of the membrane roll until the membrane roll stop 5.21 abuts against the end of the membrane roll, thereby ensuring that the membrane roll is stably and reliably gripped between the two grippers, and without affecting the rotation of the membrane roll with the membrane roll spool 5.2.
[0086] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
