Description

Technical Field

[0001] The invention relates to the technical field of film coating, and specifically relates to a film coating machine. Background Art

[0002] In order to prevent unnecessary losses caused by collisions between pipe fittings, the pipe fittings must be wrapped before leaving the warehouse.

[0003] The spacing of the clamping devices of the existing coating machines cannot be adjusted and the width of the protective film corresponds to the length of the pipe, resulting in the coating machine being able to only coat pipes of fixed specifications. Pipes of different lengths require coating machines of different specifications. The poor applicability of the coating machine is bound to lead to high investment costs, which invisibly increases the production cost of the pipes.

[0004] In addition, the existing film coating machine is not suitable for pipes with parts on the body. The parts protruding from the pipe body are easy to collide with the film feeding mechanism during film coating, thereby causing damage to the film feeding mechanism.

[0005] Especially for the arm parts of high-speed rail contact network, the arm tube needs to be transported from the pre-assembly factory to the on-site installation after pre-assembly. During the transportation process, the arm tube and parts will be collided and scratched. If the damage is serious, it will be directly scrapped.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-8 The present invention provides a technical solution: a film coating machine, comprising a machine table 1, a clamping mechanism, a film feeding mechanism 3 and a film cutting mechanism 5. The clamping mechanism is arranged on the upper surface of the machine table 1 and can reciprocate in the X-axis direction relative to the machine table 1. The film feeding mechanism 3 is mounted above the machine table 1. The film feeding mechanism 3 is used to feed the film, and the film cutting mechanism is used to cut the protective film. In this embodiment, the movement of the clamping mechanism relative to the machine table 1 is achieved by the cooperation of the slide seat and the guide rail. The clamping mechanism clamps the pipe to be coated and drives the pipe to roll. While the pipe rolls, the protective film is evenly wrapped around the pipe in cooperation with the reciprocating movement of the clamping mechanism in the X-axis direction, so that the entire pipe is wrapped with the protective film, so that the coating of the pipe is no longer limited by the width of the protective film, and is no longer limited by the distance between the clamping mechanisms. One film coating machine can be used to coat pipes of various specifications and lengths, thereby improving the applicability of the film coating machine and reducing the production cost. Especially when producing high-speed rail contact network arm parts, the film machine can be flexibly connected to the arm pre-assembly production line, and the pre-assembled arm tube can be directly clamped by the clamping mechanism after unloading. Since the length of each arm tube is different, the clamping mechanism can move freely along the X-axis to clamp arms of different lengths.

[0033] Film feeding mechanism

[0034] According to one embodiment of the present invention, the film feeding mechanism 3 includes a film feeding roller 32 and a protective film roll 31 sleeved on the film feeding roller 32. The film feeding roller 32 is driven by a film feeding motor 33 to feed the film. A pressure roller 34 is provided on one side of the film feeding roller 32. The pressure roller 34 abuts against the protective film roll 31 under the action of a torsion spring, so that the protective film roll 31 can be unloaded smoothly. The protective film fed by the protective film roll 31 is located on one side of the pipe fitting waiting for winding. The film feeding mechanism 3 is fixed on a sliding frame 61, and the sliding frame is driven by an avoidance cylinder 6 fixed on the machine 1. When the protective film roll 31 interferes with a part on the pipe fitting, it can be moved away to avoid the part. For example, in this embodiment, the pipe fitting is a wrist arm, and a clamp needs to be assembled on the wrist arm. When wrapping the film, the protective film roll 31 can use the avoidance cylinder 6 to avoid the clamp.

[0035] Film cutting mechanism

[0036] The film cutting mechanism 5 is located below the film feeding mechanism 3, and the protective film drawn out by the film feeding mechanism 3 will pass through the film cutting mechanism 5. Specifically, the film cutting mechanism 5 includes a film cutting frame 51, on which are provided a cutter 52 and a roller 53 which are arranged relatively to each other. The cutter 52 is driven by a film cutting cylinder 54 to press against the roller 53 to cut off the film passing therebetween. In the present embodiment, the film cutting mechanism 5 is also mounted on a sliding frame 61, also for the purpose of avoiding parts on the pipe fittings.

[0037] Clamping mechanism

[0038] According to one embodiment of the present invention, the clamping mechanism includes two clamping modules 2 arranged relatively on the machine table 1, the clamping module 2 includes a moving base plate 21, an X-axis cylinder 22, a Z-axis cylinder 23 and a clamping rotating head 24, wherein the moving base plate 21 can be driven by a servo screw mechanism, without specific limitation, the clamping rotating heads 24 of the two clamping modules 2 clamp the pipe fittings from both ends of the pipe fittings and drive the pipe fittings to roll, a first guide rail 26 extending along the X-axis direction is installed on the machine table 1, a first slide seat 25 is installed at the bottom of the moving base plate 21, and a motor drives the first slide seat 25 to slide back and forth along the first guide rail 26, thereby realizing the movement of each clamping module 2 in the X-axis direction separately, and when clamping the pipe fittings, according to the length of the pipe fittings, The distance between the two clamping modules 2 is adjusted to a certain degree so that the clamping modules 2 can clamp the pipe fittings. When wrapping the protective film, the two clamping modules 2 move in the same direction at the same time so that the pipe fittings are completely wrapped with the protective film. Furthermore, a second guide rail 28 extending along the Y-axis direction is installed on the upper surface of the movable base plate 21, and a second slide seat 27 slidingly matched with the second guide rail 28 is installed at the bottom of the cylinder seat of the Z-axis cylinder 23. The piston rod end of the Z-axis cylinder 23 is connected to the mounting plate of the X-axis cylinder 22, and the X-axis cylinder 22 is installed on the upper surface of the mounting plate. The clamping rotating head 24 is connected to the piston rod of the X-axis cylinder 22 through a connecting seat. When loading, the second slide seat 27 is driven to allow the components on the movable base plate 21 to move along the Y-axis direction.

[0039] Before loading, pipes to be wrapped with protective film are arranged on one side of the machine 1. The pipes to be wrapped can be pre-assembled arm tubes. The arm tubes can be unloaded by the truss robot of the arm pre-assembly platform or transmitted by a conveyor belt. There is no limitation on this.

[0040] During loading, the second slide 27 moves to drive the components on the movable base plate 21 to move to this side of the machine table 1, and then the Z-axis cylinder 23 drives the clamping rotating head 24 to move up and down to the height of the docking pipe fittings, and then the X-axis cylinder 22 drives the clamping rotating head 24 to move along the X-axis direction, so that the clamping rotating head 24 can extend into the end of the pipe fitting to clamp the pipe fitting, thereby realizing automatic loading of the coating machine.

[0041] According to one embodiment of the present invention, the clamping rotating head 24 can clamp the pipe and can rotate the winding protective film. Specifically, the clamping rotating head 24 includes a rotating motor 241 and a clamping head 242. The rotating motor 241 is installed on the connecting seat. The output shaft of the rotating motor 241 is fixedly connected to the clamping head 242. When wrapping the film, the rotating motor 241 drives the clamping head 242 to rotate.

[0042] Furthermore, an air hole 2421 is opened on the clamping head 242, and the air hole 2421 is connected to the vacuum generator and the high-temperature gas circuit respectively. Furthermore, an air source seat is fixed on the rotating motor 241, and the air source seat and the clamping head 242 are rotationally sealed. The air inlet end of the internal air circuit of the air source seat 243 is connected to the vacuum generator and the high-temperature gas circuit respectively through an electromagnetic valve, and the air outlet end of the internal air circuit of the air source seat is connected to the air circuit of the clamping head 242 through a through port 2422, and the air circuit of the clamping head 242 is connected to the air hole 2421.

[0043] Before encapsulation, a vacuum generator is used to evacuate the film, and a negative pressure is formed between the protective film delivered by the feeding mechanism 3 and the clamping head 242, so that the protective film is tightly attached to the clamping head 242, and then the clamping rotating head 24 rotates and moves along the X-axis. At this time, the protective film will be wound from the clamping rotating head 24 on one side to the pipe fitting until it is wound on the clamping rotating head 24 on the other side. The clamping rotating head 24 on this side will also absorb the protective film through negative pressure. Then the film is cut by the film cutting mechanism 5, and the closing work is carried out at the same time, that is, the high-temperature gas circuit is turned on by the solenoid valve, and the high-temperature gas circuit inputs high-temperature gas to the air hole 2421, so that the protective film is instantly hot-melted to complete the encapsulation and closing work, so that the wrapped protective film will not loosen.

[0044] After the film coating is completed, it will be transported by the unloading mechanism.

[0045] Feeding mechanism

[0046] According to one embodiment of the present invention, the coating machine provided in the present application also includes a unloading mechanism 4 for removing the pipe fittings wrapped with a protective film on the clamping mechanism. The unloading mechanism 4 is arranged under the machine platform 1. Specifically, the unloading mechanism 4 includes a receiving platform 41, a receiving base 42 and a unloading bottom plate 43. The receiving base 42 is installed on the upper surface of the unloading bottom plate 43. The receiving platform 41 is connected to the receiving base 42 through a first cylinder 44. A plurality of groups of receiving claws 45 are provided on the receiving platform 41. The first cylinder 44 drives the receiving platform 41 to reciprocate in the Z-axis direction. The receiving claws 45 pass through a unloading port (not shown in the figure) on the machine platform 1 to remove the pipe fittings wrapped with a protective film on the clamping mechanism. A unloading mechanism 4 is configured to remove the pipe fittings in a timely and safe manner after the pipe fittings are wrapped, so as to prevent the pipe fittings from falling and being damaged when the clamping mechanism releases the pipe fittings. Furthermore, the material receiving base 42 can reciprocate in the Y-axis direction relative to the material unloading base 43. In the present embodiment, the movement of the material receiving base 42 relative to the material unloading base 43 is achieved by the cooperation of the slide seat and the guide rail. Since a plurality of sets of material receiving claws 45 are provided on the material receiving platform 41, when a set of material receiving claws 45 has received a pipe fitting, it is necessary to adjust the position of the material receiving base 42 so that the other set of material receiving claws 45 are aligned with the position of the pipe fitting. In this way, the material receiving platform 41 can receive a plurality of pipe fittings and wait until all the pipe fittings are received by the material receiving claws 45 on the material receiving platform 41 before unloading, which can greatly improve the efficiency of unloading.

[0047] Working principle: loading, drive the second slide 27 to move along the Y-axis to one side of the machine 1, the Z-axis cylinder 23 drives the clamping rotary head 24 to move up and down to the height of the butted pipe fittings, adjust the distance between the two clamping modules 2 according to the length of the pipe fittings to be clamped, and then the X-axis cylinder 22 drives the clamping rotary head 24 to move along the X-axis so that the clamping rotary head 24 can extend into the end of the pipe fitting to clamp the pipe fitting, drive the second slide 27 to move to the vicinity of the center of the machine 1 to prepare for film coating; film coating, pull down one end of the protective film on the protective film roll 31 onto the pipe fitting, the vacuum generator draws vacuum to make the protective film close to the clamping head 242, and the rotating motor 241 drives the clamping head 24 2 drives the pipe to rotate and start coating. At the same time, the clamping mechanism moves along the X-axis to drive the pipe to move along the X-axis, so that the pipe is completely wrapped with the protective film. After the coating is completed, the film cutting mechanism cuts off the protective film, and then the high-temperature gas circuit inputs high-temperature gas to the air hole 2421 to instantly melt the protective film to complete the coating and closing work; for unloading, adjust the material receiving base 42 to reciprocate in the Y-axis relative to the unloading bottom plate 43, so that the material receiving claw 45 on the material receiving platform 41 is aligned with the position of the pipe to be unloaded, and the first cylinder 44 drives the material receiving platform 41 to move upward, so that the material receiving claw 45 catches the pipe, releases the clamping head 242, and the first cylinder 44 drives the material receiving platform 41 to move downward to complete the unloading.

[0048] The clamping mechanism in the coating machine provided by the present application can move in the X-axis direction, clamp the pipe fitting and rotate it to coat it, and at the same time drive the pipe fitting to move along the X-axis, that is, it coats and moves at the same time. When the width of the protective film is not enough to cover the entire pipe fitting, the entire pipe fitting can also be wrapped with the protective film, the applicability of the coating machine is improved, and the production cost is reduced; it is equipped with an automatic unloading mechanism 4. After the pipe fitting is wrapped, the unloading mechanism 4 passes through the unloading port on the machine table 1 to support the pipe fitting and remove it, so as to prevent the pipe fitting from falling and being damaged when the clamping mechanism releases the pipe fitting; the film feeding mechanism 3 is connected to the avoidance cylinder 6. When there are parts on the pipe fitting, the avoidance cylinder 6 can drive the film feeding mechanism 3 to move and avoid, so as to prevent damage to the film feeding mechanism 3 and the parts on the pipe fitting, and at the same time make the coating machine suitable for pipe fittings of more specifications and more types; loading and unloading are completed automatically, the operation is convenient, and basically no human participation is required, and the efficiency is improved.
