Description
Technical Field
[0001] The present application relates to the technical field of film production, and in particular to a film roll transfer device. Background Art
[0002] In a film production factory, it is often necessary to transfer the produced film rolls to the corresponding production and testing equipment through a transfer device, and install the roller with the film rolled up on the corresponding roller rack for processing or testing. However, for some heavier film rolls, it is difficult to transfer the film rolls to the transfer device only by manual handling, so a lifting mechanism is required for transfer.
[0003] The existing lifting device is usually installed directly on the beams of the factory building. However, since the lifting point of the lifting device is too high, the lifting device needs to move a long distance when lifting and lowering the film roll, which increases the time it takes to transfer the film roll to the transfer device, reduces the transfer efficiency of the film roll, and has obvious shortcomings. Utility Model Content
[0004] In order to improve the transfer efficiency of a film roll, the present application provides a film roll transfer device.
[0005] The film roll transfer device provided in this application adopts the following technical solution:
[0006] A film roll transfer device comprises a base plate, a transfer frame is arranged on the base plate, a lifting device is arranged on the inner top wall of the transfer frame, the lifting device comprises an electric cylinder and a driving assembly, the output shaft of the electric cylinder is provided with a cross beam, a clamping assembly for clamping the film roll is arranged on the cross beam, the driving assembly comprises a screw and a guide rod, the screw is rotatably connected to the inner top wall of the transfer frame, a mounting block is jointly arranged on the screw and the guide rod, one end of the mounting block is threadedly connected to the screw, and the other end is slidably connected to the guide rod, the electric cylinder is fixedly connected to the mounting block, a support plate for placing the film roll is arranged on the base plate, and a first motor for driving the screw to rotate is arranged on the transfer frame.
[0007] By adopting the above technical scheme, when it is necessary to transfer the produced film roll, the worker starts the electric cylinder, and the electric cylinder drives the crossbeam to move downward. When the crossbeam drops to the clamping height, the clamping assembly clamps the film roll, and then the electric cylinder drives the crossbeam to move upward. At the same time, the first motor drives the screw to rotate, and the rotation of the screw drives the mounting block to move along the screw toward the support plate. The movement of the mounting block drives the electric cylinder loaded with the film roll to move. When the film roll moves to just above the support plate, the electric cylinder drives the crossbeam downward until the film roll is placed on the support plate, and then the clamping assembly cancels the clamping effect, thereby completing the transfer operation of the film roll to the transfer rack. By arranging a lifting device on the transfer rack, the vertical distance of the film roll during the transfer process is shortened, thereby reducing the transfer time of the film roll and improving the transfer efficiency.
[0008] Optionally, a groove is provided on the crossbeam, and the clamping assembly includes a bidirectional screw rod rotatably connected in the groove, and connecting blocks are threadedly connected to the rod body at both ends of the bidirectional screw rod with opposite threads, and the connecting blocks are slidably connected in the groove, each of the connecting blocks is provided with a hook, and the hook is provided with a hanging rope, and the crossbeam is provided with a second motor that drives the bidirectional screw rod to rotate.
[0009] By adopting the above technical scheme, when the crossbeam descends to the clamping height, the second motor drives the two-way screw to rotate forward, and the two-way screw drives the two hooks to move toward the direction close to the film roll drum through the connecting block, and the hook drives the hanging rope sleeve arranged on the outer surface of the film roll, and then the crossbeam rises and the hanging rope is tensioned to complete the clamping of the clamping assembly. When the film roll needs to be released, the crossbeam descends to relax the hanging rope, and the two-way screw rotates in the opposite direction to drive the two hooks to move in the direction away from the film roll drum. At this time, the hanging rope is separated from the film roll. Such a setting realizes the clamping and release of the clamping assembly. At the same time, the two-way screw can freely adjust the clamping point according to the length of the film roll to ensure the stability of the film roll during transportation.
[0010] Optionally, limiting plates are provided on opposite sides of the support plate, and the bottom ends of the two limiting plates are inclined downward toward the center of the support plate. The opposite surfaces of the two limiting plates respectively abut against the two sides of the film roll to limit the film roll.
[0011] By adopting the above technical solution, after the film roll is placed on the support plate, it cannot temporarily leave the support plate due to the restriction of the two limit plates, thereby avoiding the phenomenon of the film roll rolling out of the support plate after being transferred to the support plate, thereby ensuring the normal operation of subsequent transportation work.
[0012] Optionally, a through slot for a trolley to enter is formed on the base plate, a guide ramp is provided on the base plate, the guide ramp is provided between the through slot and the support plate, both ends of the support plate are rotatably connected to a rotating shaft, the limit plate is fixedly connected to the outer surface of the rotating shaft, and a rotating component for driving the two rotating shafts to rotate in opposite directions is provided on the support plate.
[0013] By adopting the above technical solution, the worker pushes the bottom of the cart into the through groove, and then the rotating assembly starts to drive the rotating shaft to move in the opposite direction. The rotation of the rotating shaft drives the two limit plates to rotate, and the two limit plates gradually become horizontal and tilt upward away from the support plate. When the two limit plates are enclosed to form an inverted V shape, the film roll rolls onto the guide slope under the guidance of the inclined surface of the limit plate, and is finally transferred to the cart along the guide slope. This arrangement realizes the automatic transfer of the film roll from the transfer rack to the cart. The transfer process is automatically driven by the rotating assembly to avoid manual handling, thereby further improving the transfer efficiency of the film roll.
[0014] Optionally, the rotating assembly includes a worm wheel coaxially fixedly connected to the rotating shaft, the outer wall of the support plate is rotatably connected to a worm that is meshed with the two worm wheels, the spiral threads at both ends of the worm have opposite rotation directions, and a third motor is provided on the support plate to drive the worm to rotate.
[0015] By adopting the above technical solution, the third motor drives the worm to rotate. When the worm rotates, it drives the meshing worm wheel to rotate in the opposite direction. The worm wheel drives the rotating shaft to rotate. The rotation of the rotating shaft drives the two limit plates to rotate in opposite directions, thereby realizing the switching of the two limit plates.
[0016] Optionally, both opposite ends of the through slot are rotatably connected to hinge shafts, and the outer surfaces of the hinge shafts are commonly connected to baffles. When the two baffles abut against each other, the two baffles jointly block the through slot, and a fourth motor for driving the hinge shaft to rotate is provided on the outer side wall of the bottom plate.
[0017] By adopting the above technical solution, the worker pushes the carrying plate of the cart into the gap between the baffle and the ground, and then drives the two articulated shafts to rotate in different directions through the fourth motor. The rotation of the articulated shaft drives the baffle to rotate, and the angle between the baffle and the ground continues to increase. When the baffle is perpendicular to the ground, the fourth motor is turned off. At this time, the two vertical baffles and the carrying plate of the cart together form a moving path for the film roll. At the same time, under the protection of the baffle, the film roll will not leave the cart, ensuring the smooth progress of the film roll transfer process.
[0018] Optionally, driving grooves are provided on the opposite surfaces of the through groove, one end of the hinge shaft extends into the driving groove and is fixedly connected with a gear, the gear is rotatably arranged in the driving groove, a rack plate is slidably connected in the driving groove, the rack plate is meshing with the gear, and the opposite surfaces of the two rack plates are fixedly connected with limit baffles, and the limit baffles are slidably connected in the driving groove.
[0019] By adopting the above technical solution, in the process that the fourth motor drives the baffle to rotate in the vertical direction through the hinge shaft, the hinge shaft drives the two gears to rotate in opposite directions, the rotation of the gear drives the rack plate to move, and the movement of the rack plate drives the limit baffle to gradually extend out of the driving groove. At this time, the surface of the limit baffle facing the guide slope abuts against the surface of the cart bearing plate, and the cart cannot move out of the through groove due to the restriction of the limit baffle. Such a setting ensures the stability of the cart in the through groove, reduces the possibility of the cart moving when the film roll rolls onto the cart, and further improves the stability of the transfer process.
[0020] Optionally, a plurality of universal wheels are provided at opposite ends of the base plate.
[0021] By adopting the above technical solution, the setting of the universal wheel makes it convenient for workers to adjust the position of the transfer rack according to the position of the production equipment, thereby facilitating the lifting device on the transfer rack to transfer the completed film roll to the transfer rack, further improving the transfer efficiency of the film roll.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. The present application provides a transfer rack and a lifting device. By providing a lifting device on the transfer rack, the vertical distance of the film roll during the transfer process is shortened, thereby reducing the transfer time of the film roll and improving the transfer efficiency;
[0024] 2. The present application sets a limit plate, a rotating assembly, a guide slope and a through groove. The worker pushes the bottom of the cart into the through groove, and then starts the rotating assembly to drive the limit plate to rotate. When the two limit plates are enclosed to form an inverted V shape, the film roll rolls onto the guide slope under the guidance of the inclined surface of the limit plate, and is finally transferred to the cart along the guide slope. This setting realizes the automatic transfer of the film roll from the transfer rack to the cart. The transfer process is automatically driven by the rotating assembly to avoid manual handling, thereby further improving the transfer efficiency of the film roll. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0030] The following is combined with Figure 1-4 This application is described in further detail.
[0031] The embodiment of the present application discloses a film roll transfer device.
[0032] Reference Figure 1 A film roll transfer device includes a base plate 1, a transfer frame 2 is fixedly installed on the base plate 1, a plurality of universal wheels 101 are fixedly installed on the bottom end of the base plate 1, a lifting device 3 is provided on the transfer frame 2, and a support plate 4 for placing the film roll is fixedly connected to one end of the base plate 1. The worker pushes the transfer frame 2 to an area near the production equipment through the universal wheel 101, and then transfers the produced film roll to the support plate 4 on the transfer frame 2 through the lifting device 3.
[0033] Reference Figure 1 and Figure 2 The lifting device 3 includes an electric cylinder 31 and a driving assembly 32. The driving assembly 32 includes a screw 321 and a guide rod 322 connected to the inner top wall of the transfer frame 2 through an ear plate. The screw 321 and the guide rod 322 are arranged in parallel. The screw 321 and the guide rod 322 are arranged along the length direction of the film roll. A first motor 323 is fixedly installed on the outer wall of the transfer frame 2. The output shaft of the first motor 323 is coaxially fixedly connected to the screw 321. A mounting block 324 is commonly provided on the screw 321 and the guide rod 322. One end of the mounting block 324 is threadedly connected to the screw 321, and the other end is slidably connected to the guide rod 322.
[0034] Reference Figure 1 and Figure 2 The electric cylinder 31 is fixedly mounted on the mounting block 324, the output shaft of the electric cylinder 31 is fixedly connected to the crossbeam 33, the crossbeam 33 is parallel to the screw rod 321, a clamping assembly 5 for clamping the film roll is arranged on the crossbeam 33, a groove 331 is opened on the crossbeam 33, the length direction of the groove 331 is parallel to the length direction of the crossbeam 33, the clamping assembly 5 includes a bidirectional screw rod 51 rotatably connected in the groove 331, two sections of the rod body with opposite thread rotation directions of the bidirectional screw rod 51 are threadedly connected with a connecting block 52, the connecting block 52 is slidably connected in the groove 331, the cross sections of the connecting block 52 and the groove 331 are both square, so as to limit the rotation of the connecting block 52 in the groove 331, each connecting block 52 is fixedly connected to a hook 53, a circular hanging rope 54 is fixedly connected to the hook 53, a second motor 55 is fixedly mounted on the outer wall of the crossbeam 33, and the output shaft of the second motor 55 is coaxially fixedly connected to the bidirectional screw rod 51.
[0035] When the film roll needs to be transported after production, the electric cylinder 31 is started, and the electric cylinder 31 drives the crossbeam 33 to move downward. When the crossbeam 33 drops to the clamping height, the second motor 55 drives the bidirectional screw rod 51 to rotate forward, and the bidirectional screw rod 51 drives the two hooks 53 to move toward the direction close to the film roll drum through the connecting block 52. The hook 53 drives the hanging rope 54 to be sleeved on the outer surface of the film roll. Then the electric cylinder 31 drives the crossbeam 33 to rise to tighten the hanging rope 54. At this time, the film roll is clamped by the clamping assembly 5. Then the electric cylinder 31 drives the crossbeam 33 to move upward. At the same time, the first motor 323 drives the screw rod 321 to rotate. The rotation of the screw rod 321 drives the mounting block 324 to move along the screw rod 321 toward the support plate 4. The mounting block 32 4 moves and drives the electric cylinder 31 loaded with the film roll to move. When the film roll moves to just above the support plate 4, the electric cylinder 31 drives the crossbeam 33 downward until the film roll is placed on the support plate 4. At this time, the hanging rope 54 is relaxed, and the two-way screw rod 51 rotates in the opposite direction to drive the two hooks 53 to move in the direction away from the film roll drum. The hook 53 pulls the hanging rope 54 away from the film roll, thereby completing the transfer operation of the film roll to the transfer rack 2. By arranging the lifting device 3 on the transfer rack 2, the vertical distance of the film roll during the transfer process is shortened, thereby reducing the transfer time of the film roll and improving the transfer efficiency. At the same time, the two-way screw rod 51 can freely adjust the clamping point according to the length of the film roll to ensure the stability of the film roll during the transfer process.
[0036] Reference Figure 1 and Figure 3, the two opposite sides of the support plate 4 are rotatably connected with the rotating shaft 6, the outer surface of the rotating shaft 6 is fixedly connected with the limiting plate 61, and the support plate 4 is provided with a rotating assembly 7 for driving the two rotating shafts 6 to rotate in opposite directions. When the limiting plates 61 are in a limited state, the bottom ends of the two limiting plates 61 are inclined downward toward the center direction of the support plate 4, and the two limiting plates 61 are enclosed to form a V shape, and the opposite surfaces of the two limiting plates 61 are respectively against the two sides of the film roll to limit the film roll;
[0037] When the limit plate 61 is in a non-limiting state, the top ends of the two limit plates 61 are tilted upward toward the center of the support plate 4, and the two limit plates 61 are combined to form an inverted V shape. The end of the bottom plate 1 away from the support plate 4 is provided with a through groove 8 for the trolley 01 to be pushed in. A guide slope 9 is fixedly connected to the bottom plate 1, and the guide slope 9 is arranged between the through groove 8 and the support plate 4. The high end of the guide slope 9 is arranged close to the support plate 4, and the low end is arranged close to the through groove 8. The opposite ends of the bottom plate 1 are fixedly connected with protective plates, which are arranged on both sides of the guide slope 9 to limit the transportation of the film roll.
[0038] Reference Figure 3 The rotating assembly 7 includes a worm gear 71 coaxially fixedly connected to the rotating shaft 6. A worm 72 that is rotatably connected to the support plate 4 through an ear plate and is meshed with the two worm gears 71 is provided. The spiral patterns at both ends of the worm gear 72 have opposite rotation directions. A third motor 73 is fixedly mounted on the support plate 4, and the output shaft of the third motor 73 is coaxially fixedly connected to the worm gear 72.
[0039] The worker pushes the bottom of the cart 01 into the through groove 8, and the third motor 73 drives the worm 72 to rotate. When the worm 72 rotates, it drives the meshing worm wheel 71 to rotate in the opposite direction. The worm wheel 71 drives the rotating shaft 6 to rotate, and the rotation of the rotating shaft 6 drives the two limit plates 61 to rotate. The two limit plates 61 gradually become horizontal and tilt upward in the direction away from the support plate 4. When the two limit plates 61 are surrounded to form an inverted V shape, the film roll rolls onto the guide ramp 9 under the guidance of the inclined surface of the limit plate 61, and is finally transferred to the cart 01 along the guide ramp 9. This arrangement realizes the automatic transfer of the film roll from the transfer rack 2 to the cart 01. The transfer process is automatically driven by the rotating component 7 to avoid manual handling, thereby further improving the transfer efficiency of the film roll.
[0040] Reference Figure 3 and Figure 4 The two opposite ends of the through slot 8 are rotatably connected with hinge shafts 10, and the length directions of the two hinge shafts 10 are parallel to the length direction of the through slot 8. A fourth motor 11 for driving the hinge shafts 10 to rotate is fixedly installed on the outer peripheral side wall of the bottom plate 1. A baffle 12 is commonly connected to the outer surface of each hinge shaft 10. When the two baffles 12 abut against each other in the horizontal direction, the two baffles 12 jointly block the through slot 8.
[0041] The worker pushes the load-bearing plate of the cart 01 into the gap between the bottom surface of the baffle 12 and the ground, and then drives the two articulated shafts 10 to rotate in different directions through the fourth motor 11. The rotation of the articulated shaft 10 drives the baffle 12 to rotate, and the angle between the baffle 12 and the ground continues to increase. When the baffle 12 is perpendicular to the ground, the fourth motor 11 is turned off. At this time, the two vertical baffles 12 and the load-bearing plate of the cart 01 together form a moving path for the film roll. At the same time, under the protection of the baffle 12, the film roll will not separate from the cart 01, ensuring the smooth progress of the film roll transfer process.
[0042] Reference Figure 3 and Figure 4 , driving grooves 13 are provided on the opposite surfaces of the through groove 8, and the length direction of the driving groove 13 is perpendicular to the length direction of the hinge shaft 10. One end of the two hinge shafts 10 extends into the driving groove 13 and is fixedly connected with a gear 14. The gear 14 is rotatably set in the driving groove 13, and a rack plate 15 is slidably connected in the driving groove 13. The rack plate 15 is meshed with the gear 14. The opposite surfaces of the two rack plates 15 are fixedly connected with a limit baffle 151, and the limit baffle 151 is slidably connected in the driving groove 13.
[0043] When the fourth motor 11 drives the baffle 12 to rotate in the vertical direction through the hinge shaft 10, the hinge shaft 10 drives the two gears 14 to rotate in opposite directions. The gear 14 rotates to drive the rack plate 15 to move. The movement of the rack plate 15 drives the limit baffle 151 to gradually extend out of the driving groove 13. At this time, the surface of the limit baffle 151 facing the guide ramp 9 abuts against the surface of the bearing plate of the cart 01. The cart 01 cannot move out of the through groove 8 due to the restriction of the limit baffle 151. This arrangement ensures the stability of the cart 01 in the through groove 8, reduces the possibility of the cart 01 moving when the film roll rolls onto the cart 01, and further improves the stability of the transportation process.
[0044] The implementation principle of a film roll transfer device in an embodiment of the present application is as follows: when the produced film roll needs to be transferred, the electric cylinder 31 is started, and the electric cylinder 31 drives the cross beam 33 to move downward. When the cross beam 33 drops to the clamping height, the second motor 55 drives the bidirectional screw rod 51 to rotate forward, and the bidirectional screw rod 51 drives the two hooks 53 to move toward the direction close to the film roll drum through the connecting block 52. The hook 53 drives the hanging rope 54 to be sleeved on the outer surface of the film roll, and then the electric cylinder 31 drives the cross beam 33 to rise to tighten the hanging rope 54. At this time, the film roll is clamped by the clamping assembly 5, and then the electric cylinder 31 drives the cross beam 33 to move upward. At the same time, the first motor 323 drives the screw rod 321 to rotate, and the rotation of the screw rod 321 drives the mounting block 324 to move along the screw 321 toward the support The support plate 4 moves, and the mounting block 324 moves to drive the electric cylinder 31 loaded with the film roll to move. When the film roll moves to just above the support plate 4, the electric cylinder 31 drives the crossbeam 33 downward until the film roll is placed on the support plate 4. At this time, the hanging rope 54 is relaxed, and the two-way screw rod 51 rotates in the opposite direction to drive the two hooks 53 to move in the direction away from the film roll drum. The hook 53 pulls the hanging rope 54 off the film roll, thereby completing the transfer operation of the film roll to the transfer rack 2. By arranging the lifting device 3 on the transfer rack 2, the vertical distance of the film roll during the transfer process is shortened, thereby reducing the transfer time of the film roll and improving the transfer efficiency. At the same time, the two-way screw rod 51 can freely adjust the clamping point according to the length of the film roll to ensure the stability of the film roll during the transfer process.
[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
