Description

Technical Field

[0001] This invention relates to the field of automated production line equipment for filling film conveying, and specifically to a method for thermal bonding of film using a material trolley in conjunction with film bonding equipment. Background Technology

[0002] When the film splicing equipment continuously supplies filling film, it is necessary to thermally bond the previous roll of film to the next roll to ensure a continuous and uninterrupted supply of film material. When the supply of the previous roll of film is detected to be at the end, the film material needs to be cut so that the splicing head can thermally bond the end of the previous roll of film to the beginning of the next roll of film.

[0003] Current technologies for thermally bonding films have low levels of automation. When the previous roll of film reaches the end of its supply, the splicing equipment must be stopped, and the next roll of film must be reinstalled before thermal bonding can proceed. This results in low bonding efficiency and high labor intensity for workers. Furthermore, existing material trolleys only function to carry and transport the filling film and cannot assist the splicing equipment in completing the thermal bonding between the previous and next rolls of film. If the material trolley could assist the splicing equipment in completing the film-to-film bonding, the efficiency of film thermal bonding could be greatly improved, while simultaneously reducing the labor intensity for workers.

[0004] In summary, there is an urgent need for a method for thermal bonding of membranes using a material trolley in conjunction with a membrane bonding device to solve the problems existing in the prior art. Summary of the Invention

[0005] The purpose of this invention is to provide a method for thermal bonding of membranes using a material trolley in conjunction with a membrane bonding device, aiming to solve the problem that existing material trolleys cannot assist the membrane bonding device in completing the thermal bonding between membranes. The specific technical solution is as follows:

[0006] A method for thermal bonding of film using a material trolley in conjunction with a film bonding device, the material trolley comprising a trolley body and n unwinding assemblies and n working station assemblies all disposed on the trolley body, the unwinding assemblies being used to place the roll film, and the working station assemblies being used to place the first section of film material released from the roll film, wherein n is a natural number greater than or equal to 1.

[0007] The work station assembly includes a work station panel and a film pressing rod. The work station panel has a lower cutting groove and a film pressing groove arranged in parallel. The film pressing rod is movably disposed in the film pressing groove. After the film roll releases the film material, the first section of the film material is placed on the work station panel, and the end of the first section of the film material is placed in the film pressing groove. The film pressing rod applies pressure to the film material below it. When the external force on the film material is greater than the pressure applied by the film pressing rod, the film material will be pulled out from below the film pressing rod.

[0008] In a preferred embodiment of the above technical solution, the work station assembly further includes k rollers, and the film material released from the roll passes around the k rollers in sequence and is placed on the upper surface of the work station panel; where k is a natural number greater than or equal to 1, and the highest point on the roller surface circle of the last roller is flush with the upper surface of the work station panel.

[0009] In the preferred embodiment of the above technical solutions, the pressing rod is magnetically adsorbed in the pressing groove.

[0010] In the preferred embodiment of the above technical solution, m sets of film bonding station components are arranged side by side on the top of the vehicle body. The film bonding station components include an installation frame and multiple sets of working station components arranged along the length of the installation frame, where m is a natural number greater than or equal to 1.

[0011] In the preferred embodiment of the above technical solutions, the vehicle body includes a chassis frame and handrails and an unwinding frame both mounted on the chassis frame, and the unwinding assembly and the film splicing station assembly are both mounted on the unwinding frame.

[0012] In a preferred embodiment of the above technical solutions, the unwinding assembly includes an air shaft, a bearing, an unwinding base plate, and a magnetic damper disposed on the unwinding base plate. The air shaft is rotatably disposed on the unwinding base plate via the bearing, and the air shaft passes through the bearing and the unwinding base plate before connecting to the magnetic damper.

[0013] In the preferred embodiment of the above technical solutions, the air shaft is provided with an unwinding disc, and the end face of the film sleeved on the air shaft abuts against the unwinding disc.

[0014] In the preferred embodiment of the above technical solution, the bottom of the vehicle body is provided with multiple pairs of traveling wheels, at least one pair of guide wheels, and at least one pair of clamping blocks. The traveling wheels are used for the movement of the material cart, the guide wheels are used to guide the movement of the material cart, and the clamping blocks are used to clamp the material cart with the clamping device.

[0015] In the preferred embodiment of the above technical solutions, the bottom of the vehicle body is provided with a booster seat, and the driving wheels are mounted on the booster seat.

[0016] In a preferred embodiment of the above technical solutions, the bottom of the vehicle body is further provided with a wear-resistant component for supporting and lifting the material trolley; the wear-resistant component includes a wear-resistant strip, a mounting frame, and anti-collision rollers, with anti-collision rollers provided at both ends of the mounting frame, and the wear-resistant strip is disposed on the mounting frame.

[0017] The application of the technical solution of the present invention has the following beneficial effects:

[0018] The material trolley of this invention is equipped with multiple working station components. Each working station panel has a cutting groove and a pressing groove. The pressing rod and the pressing groove work together to press the end of the film material, ensuring it is laid flat on the working station panel. The film receiving head assembly, in conjunction with the cutting groove, presses the film material on both sides of the cutting groove, ensuring the cutting head can smoothly cut the film material. After cutting, the film receiving head assembly moves with the film material to the top of the next working station component, allowing the film material on the receiving head assembly to be pressed against the flatly laid film material on the next working station component, thus completing the thermal bonding between the films. Since the pressure applied by the pressing rod to the film material is not high, after bonding, the end of the new roll of film can be automatically pulled out from under the pressing rod, allowing for continued film supply without manual intervention. This material trolley can work with film splicing equipment to complete film cutting and splicing, enabling continuous supply of n rolls of film material in a single loading operation, without manual intervention, greatly improving splicing efficiency and reducing worker workload.

[0019] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

[0034] To facilitate understanding of the present invention, a more comprehensive description is provided below, along with preferred embodiments. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0036] Example:

[0037] This embodiment provides a material trolley for membrane conveying. The material trolley is used to supply membrane material to the membrane splicing equipment, enabling the continuous output of membrane material from the membrane splicing equipment, and assisting the membrane splicing head assembly of the membrane splicing equipment in completing the thermal bonding between the tail section of the previous roll of film and the head section of the next roll of film.

[0038] See Figures 1-7 The material trolley 200 includes a trolley body 203 and n unwinding assemblies 202 and n working station assemblies, all of which are disposed on the trolley body 203 (i.e., n rolls of film can be placed on the material trolley). The i-th unwinding assembly 202 is used to place the i-th roll of film, and the i-th working station assembly is used to place the first section of film material A01 released from the i-th roll of film. n is a natural number greater than or equal to 1, and i is a natural number and 1≤i≤n.

[0039] Please see Figure 5 and Figure 6 The work station assembly includes a work station panel 2014 and a film pressing rod 2015. The work station panel 2014 is provided with a lower knife groove 2013 and a film pressing groove (not shown in the figure) in parallel. The film pressing rod 2015 is movably disposed in the film pressing groove. After the film roll releases the film material A01, the first section of the film material A01 is placed on the work station panel 2014, and the end of the first section of the film material is placed in the film pressing groove. The film pressing rod 2015 applies pressure to the film material below it. When the external force on the film material is greater than the pressure applied by the film pressing rod 2015, the film material A01 will be pulled out from below the film pressing rod 2015.

[0040] Specifically, the lower cutting groove 2013 is used to cut the film material with a lower cutter. That is, when the film roll has been supplied to the end section (the end section of the film material is generally identified by a sensor, such as a color mark sensor), the cutter on the film splicing head assembly moves down into the lower cutting groove to cut the film material.

[0041] Please see Figure 5 and Figure 6 The workstation panel is divided into panel one and panel two (not shown in the figure) by a lower cutting groove. Panel one and panel two cooperate with the film receiving head assembly to press the film material tightly on both sides of the lower cutting groove. Panel one is also used for subsequent thermal bonding of the film with the film receiving head assembly. Panel one, in conjunction with the film receiving head assembly, presses the film material on one side of the lower cutting groove, while panel two, in conjunction with the film receiving head assembly, presses the film material on the other side of the lower cutting groove. Then, the cutter moves down into the lower cutting groove to smoothly cut the film material. Furthermore, to facilitate thermal bonding of the film, the pressing groove is provided on panel one, specifically on the side of panel one away from the lower cutting groove. The surface of panel two can be provided with multiple grooves to increase the contact area with the film during pressing.

[0042] Please see Figure 5 and Figure 6 The work station assembly also includes k rollers. The film material A01 released from the roll film passes around the k rollers in sequence and is placed on the upper surface of the work station panel 2014. Here, k is a natural number greater than or equal to 1, and the highest point on the roller surface circle of the last roller is flush with the upper surface of the work station panel. Furthermore, the last roller is set close to the second panel.

[0043] In this embodiment, the roller surface circle refers to the circle formed by the circumferential surface of the roller, which is used to contact the film material. The highest point of the roller surface circle of the last roller is flush with the upper surface of the workstation panel, which allows the film material to be directly laid horizontally onto panel two and panel one after it comes out of the last roller (that is, the film material laid on the workstation panel is tangent to the last roller). Then, the end of the film material is placed in the pressing groove and pressed with a pressing rod to complete the installation of the film material on the material trolley 200.

[0044] In this embodiment, a work station component includes roller 1 2012 and roller 2 2016, wherein roller 2 is the last roller closest to the work station panel; by arranging the rollers, the film material can be tensioned and the film direction can be adjusted.

[0045] Preferably, in this embodiment, the pressing rod 2015 is magnetically adsorbed in the pressing groove. At least one of the pressing groove or the pressing rod is equipped with a magnet, so that the pressing rod is magnetically adsorbed after being placed in the pressing groove. One end of the pressing rod and the pressing groove can be hinged, and the pressing rod can be pressed into and out of the pressing groove by rotating the pressing rod; alternatively, the pressing rod and the pressing groove can be connected only by magnetic adsorption, in which case the pressing rod can be completely removed from the pressing groove. Magnetic adsorption can apply a certain pressure to the film material below the pressing rod, but it is still sufficient to ensure that the external force on the film material (this external force is generated by the upward movement of the film receiving head assembly after thermal bonding; that is, after the film thermal bonding is completed, the upward movement of the film receiving head assembly will carry the film material away from the workstation panel) is greater than this pressure, so that the film material can be pulled out from below the pressing rod.

[0046] In this preferred embodiment, the top of the vehicle body 203 is provided with m sets of film-attachment station assemblies 201 arranged in parallel. Each film-attachment station assembly 201 includes a mounting frame 2011 and multiple sets of working station assemblies arranged along the length of the mounting frame 2011, where m is a natural number greater than or equal to 1. Preferably, under normal circumstances, n working station assemblies are evenly distributed on the m sets of film-attachment station assemblies. However, in some special cases, the number of working station assemblies on each film-attachment station assembly may be inconsistent.

[0047] In this embodiment, there are two sets of film-attaching station assemblies, each with four working station components arranged on it. Generally, the film-attaching head assembly slides only along the arrangement direction of the working station components on the film-attaching station assembly. Switching the film-attaching station components to a working position below the film-attaching head assembly requires movement of the material trolley. However, in some embodiments, the material trolley may not need to move; instead, the film-attaching head assembly can move horizontally and vertically in the horizontal plane to be positioned above the working components.

[0048] Please see Figure 3The vehicle body 203 includes a chassis 2031 and handrails and an unwinding frame 2033, both mounted on the chassis 2031. The unwinding assembly 202 and the film splicing station assembly 201 are both mounted on the unwinding frame 2033. Specifically, the top of the unwinding frame 2033 has two sets of film splicing station assemblies 201, and each side of the unwinding frame 2033 has four unwinding assemblies 202. The handrails are used to facilitate the movement of the material cart by the operator.

[0049] Please see Figure 4 The unwinding assembly 202 includes an air shaft 2021, a bearing 2023, an unwinding base plate 2024, and a magnetic damper 2025 disposed on the unwinding base plate 2024. The air shaft 2021 is rotatably disposed on the unwinding base plate 2024 through the bearing 2023. The air shaft 2021 passes through the bearing 2023 and the unwinding base plate 2024 and is connected to the magnetic damper 2025.

[0050] Furthermore, the air shaft 2021 is provided with an unwinding disc 2022, and after the film is sleeved on the air shaft 2021, its end face abuts against the unwinding disc 2022.

[0051] In this embodiment, the unwinding base plate 2024 is fixed to the unwinding frame 2033 with screws. The air shaft 2021 is preferably a flange-type air shaft. The unwinding disc is set on the flange of the air shaft. After the film roll is sleeved on the air shaft, the air shaft clamps the film roll, and at the same time, the inner end face of the film roll (referring to the end face near the magnetic damper) abuts against the unwinding disc. The magnetic damper provides damping force to the rotation of the film roll, preventing the film roll from rotating freely and causing excessive release of film material, which would result in the film material not being in a taut state.

[0052] See Figure 2 The bottom of the vehicle body 203 is provided with multiple pairs of traveling wheels, at least one pair of guide wheels 206 and at least one pair of clamping blocks 208. The traveling wheels are used for the movement of the material cart, the guide wheels 206 are used to guide the movement of the material cart, and the clamping blocks 208 are used to clamp the material cart with the clamping device.

[0053] Furthermore, the bottom of the vehicle body is provided with a riser seat 209, and the traveling wheels are mounted on the riser seat 209. By adding the riser seat 209 to the bottom of the vehicle body, the clearance at the bottom of the vehicle body can be increased, which facilitates the installation of clamping blocks at the bottom of the vehicle body, without affecting the normal movement of the material cart. Specifically, in this embodiment, the traveling wheels include a pair of directional wheels 204 and a pair of omnidirectional wheels 205. The omnidirectional wheels 205 allow operators to easily adjust the direction of travel when pushing the material cart.

[0054] The guide wheel 206 is used to guide the forward movement of the material trolley, specifically to guide its movement on the guide rail of the conveying assembly. After the film roll on the material trolley is installed, it needs to be manually pushed (or automatically driven, such as by an AGV) to the film splicing equipment. During film conveying and splicing, it is necessary to ensure that the working station components are in the working position so that the film splicing equipment can work normally. This requires high positional accuracy for the material trolley, so it needs to be moved to the designated position by the conveying assembly (usually a ground rail device). To ensure that the material trolley can smoothly enter the conveying assembly, the guide wheel 206 needs to be set to roll in contact with the guide rail in the conveying assembly to achieve motion guidance. The clamping block 208 is used to enable the conveying component to smoothly clamp the material trolley. The conveying component is equipped with a sliding gripper assembly. The gripper assembly is moved to the clamping block of the material trolley and clamped. Then the material trolley can slide on the conveying component with the gripper assembly to realize the sliding of the work station assembly to the work position. At the same time, each film splicing station assembly 201 also switches to the work position by following the movement of the gripper assembly.

[0055] Furthermore, to ensure the material trolley remains stationary during film bonding operations, the conveying assembly typically includes a support component to fully elevate the material trolley. When fully elevated, the wheels are suspended and provide no support; the trolley can only move along the support component following the gripper assembly. Correspondingly, in this embodiment, a wear-resistant component 207 for supporting and lifting the material trolley is provided at the bottom of the trolley body 203. In the elevated state, the wear-resistant component rests directly on the support component, and the material trolley is supported by the support component and the wear-resistant component. Further, the wear-resistant component 207 includes a wear-resistant strip 2071, a mounting frame 2072, and anti-collision rollers 2073. Anti-collision rollers 2073 are provided at both ends of the mounting frame 2072, and the wear-resistant strip 2071 is disposed on the mounting frame 2072.

[0056] Preferably, the wear-resistant strip has inclined surfaces at both ends, and the bottom surface of the middle part of the wear-resistant strip is lower than the bottom surface of the anti-collision roller (i.e., the anti-collision roller will be suspended in the supporting state). Correspondingly, the support member of the conveying assembly also has inclined surfaces at both ends. This is to reduce the difficulty for the material trolley to climb onto the support member. As the material trolley moves with the gripper assembly, the anti-collision roller 2073 will first contact the inclined surface of the support member. During the movement, the anti-collision roller will slowly climb onto the inclined surface of the support member, and finally climb onto the upper surface of the support member, thus completing the process of the material trolley completely climbing onto the support member and being supported by the support member. The ends of the wear-resistant strip are set with inclined surfaces to prevent the ends of the wear-resistant strip from pressing against the inclined surface of the support member during the process of the anti-collision roller climbing onto the inclined surface of the support member, generating excessive movement resistance.

[0057] Furthermore, in actual setups, depending on the structural form, a wear-resistant component may be installed at the middle position of the bottom of the vehicle body to meet the support requirements of the material trolley; or, as in this embodiment, two wear-resistant components may be symmetrically installed at the bottom of the material trolley to meet the support requirements of the material trolley; the specific arrangement of the wear-resistant components depends on the arrangement of the support components in the conveying assembly.

[0058] In this embodiment, the material cart works in conjunction with the film splicing equipment to transport the membrane, specifically:

[0059] After the material trolley's work station component arrives at the working position of the film splicing equipment, the film material released from the roll passes through k rollers in sequence and enters the film splicing head component of the film splicing equipment. Then, the film conveying component of the film splicing equipment outputs the film material from the film splicing equipment.

[0060] In this embodiment, the material cart works in conjunction with the film bonding equipment to perform thermal bonding of the membrane, specifically:

[0061] A1. When it is detected that the current roll of film has been supplied to the end, the film splicing equipment stops the film feeding, and then the film splicing head assembly moves down to press the film material on the lower station panel;

[0062] A2. The cutter in the film receiving head assembly moves down to the lower cutting groove to cut the film material. After cutting, the film material on one side of the lower cutting groove is vacuum-adsorbed onto the film receiving head assembly, while the film material on the other side of the lower cutting groove remains on the material trolley waiting for the operator to remove it.

[0063] A3. The film material adsorbed by vacuum moves with the film splicing head assembly to the top of the next workstation panel, ready to be thermally bonded to the head section of the next roll of film.

[0064] A4. The film splicing head assembly descends and presses against the workstation panel. The film material that has been vacuum-adsorbed and the film material on the workstation panel are pressed together. The film splicing head assembly generates heat to complete the thermal bonding between the film material on the film splicing head assembly and the film material on the workstation panel.

[0065] A5. After the heat bonding is completed, the film splicing head assembly moves upward, and the film splicing equipment continues to supply film material.

[0066] The effect of applying the technical solution of this invention is:

[0067] The material trolley of this invention is equipped with multiple working station components. Each working station panel has a cutting groove and a pressing groove. The pressing rod and the pressing groove work together to press the end of the film material, ensuring it is laid flat on the working station panel. The film receiving head assembly, in conjunction with the cutting groove, presses the film material on both sides of the cutting groove, ensuring the cutting head can smoothly cut the film material. After cutting, the film receiving head assembly moves with the film material to the top of the next working station component, allowing the film material on the receiving head assembly to be pressed against the flatly laid film material on the next working station component, thus completing the thermal bonding between the films. Since the pressure applied by the pressing rod to the film material is not high, after bonding, the end of the new roll of film can be automatically pulled out from under the pressing rod, allowing for continued film supply without manual intervention. This material trolley can work with film splicing equipment to complete film cutting and splicing, enabling continuous supply of n rolls of film material in a single loading operation, without manual intervention, greatly improving splicing efficiency and reducing worker workload.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
