[0028] Example

[0029] A fully automatic film wrapping device, such as Figures 1-4 As shown, it includes a frame 1, a top film winding device, and a side film winding device.

[0030] The frame 1 includes a base 101, columns 102, and a frame body 103. The base 101 is fixed to the ground, for example, by screws or anchor bolts. The columns 102 are arranged vertically and fixed to the base 101. There are usually two columns 102 forming a gantry shape. The frame body 103 is slidably connected to the columns 102. For example, both columns 102 are equipped with slide rails. The frame body 103 is equipped with sliders or grooves that cooperate with the slide rails. The frame body 103 is usually a planar frame structure to facilitate the arrangement of the top film winding device.

[0031] The side film winding device includes a turntable 2, a turntable drive mechanism 5, a roll support base 6, a lifting drive mechanism 7, a side film roll 8, a side film clamping mechanism 9, a film clamping and lifting mechanism 10, a side film cutting mechanism 11, and a film cutting drive mechanism 13.

[0032] The turntable 2 is rotatably connected to its configured support via a shaft and bearings, which is fixed to the ground for use; or the turntable 2 is rotatably connected to the base 101 via a shaft and bearings. The shaft configured on the turntable 2 is arranged vertically (i.e., in the height direction), and the top surface of the turntable 2 is horizontal. The turntable 2 is used to carry the product 3 to be wrapped with film, which is usually carried by a tray 4 and placed on the turntable 2.

[0033] The turntable drive mechanism 5 is also fixedly mounted on the ground or on the base 101. For example, the turntable drive mechanism 5 includes a turntable motor 51, a driving gear 52, and a driven gear 53. The turntable motor 51 is fixedly mounted on the ground by screws or bolts, the driving gear 52 is fixed on the motor shaft of the turntable motor 51, and the driven gear 53 is coaxially fixedly mounted on the turntable 2. Of course, in other embodiments, the turntable drive mechanism 5 can also be that the turntable motor 51 directly drives the shaft fixed on the turntable 2 to rotate through a reducer and a coupling. In this case, the turntable drive mechanism 5 is arranged on the lower side of the turntable 2 to prevent it from affecting the arrangement of the product 3 on the turntable 2.

[0034] The coil support 6 is slidably connected to the frame 1 vertically. For example, the base 101 is fixed with a vertically arranged slide rail, and the coil support 6 is slidably connected to the slide rail. The lifting drive mechanism 7 is fixedly installed on the base 101. The lifting drive mechanism 7 is, for example, any device capable of outputting linear motion in the vertical direction, such as a cylinder, hydraulic cylinder, electric cylinder, or gear and rack transmission structure driven by a motor. Its output end is fixedly connected to the coil support 6, thereby driving the coil support 6 to reciprocate vertically.

[0035] The side film roll 8 is used to unwind the side film. It has a hollow cavity. A fixed rod or fixed shaft with a diameter smaller than the hollow cavity is fixed on the roll support 6, so that the side film roll 8 can rotate freely while being sleeved on it.

[0036] The side film clamping mechanism 9 is slidably connected to the turntable 2 vertically. The side film clamping mechanism 9 includes a frame 91, grippers 92, and gripper drive 93. Typically, the side film clamping mechanism 9 is not directly mounted on the turntable 2. Instead, a wall panel 201 is first fixedly mounted on the turntable 2, for example, by screws. Then, the frame 91 is slidably connected to the wall panel 201 via a slide rail groove or slide rail slider structure. The film clamping lifting mechanism 10 is fixedly mounted on the wall panel 201. The film clamping lifting mechanism 10 can be any device capable of outputting linear motion in the vertical direction, such as a cylinder, hydraulic cylinder, electric cylinder, or a gear and rack transmission structure driven by a motor. Its output end is connected to the frame 91, thereby driving the frame 91 to reciprocate vertically.

[0037] There are two grippers 92, and their midpoints along their length are staggered. The two grippers 91 are rotatably connected to the frame 91 at the intersection via the same pivot axis, which is horizontal. This allows the two grippers 92 to clamp the side film roll 8 when their upper parts come together, and to release the side film when they separate. The gripper drive 93 is any device capable of outputting linear motion in the vertical direction, such as a cylinder, hydraulic cylinder, electric cylinder, or a gear and rack transmission structure driven by a motor. It is fixedly mounted on the frame 91, and its output end is connected to two connecting rods 94. The two connecting rods 94 are respectively connected to the lower ends of the two grippers 92. Thus, when the output end of the gripper drive 93 moves upward, it causes the two grippers 93 to release the side film; when the output end of the gripper drive 93 moves downward, it causes the two grippers 93 to clamp the side film.

[0038] The side-cutting mechanism 11 is movably mounted on the base 101, or it can also be movably mounted on the ground. The side-cutting mechanism 11 includes a support column 111, a support base 112, a support plate 113, a brush 114, a cutting blade 115, and an air nozzle 116.

[0039] The support column 111 is arranged vertically and can be rotatably connected to the base 101 via bearings, or slidably connected to the base 101 via a slide rail slider or slider groove structure. This allows the distance between the cutting blade 115 and the product 3 to be changed during sliding, enabling the cutting blade 115 to approach the product 3 and cut the side film. Typically, the sliding direction of the support column 111 relative to the base 101 is approximately perpendicular to the pulling direction of the side film, which is the direction in which the side film is pulled towards the product 3 during winding. This pulling direction is usually approximately parallel to the feeding and discharging direction of the product 3. Of course, in other preferred embodiments, the pulling direction of the side film can also be approximately perpendicular to the feeding and discharging direction of the product 3. To avoid the side film cutting mechanism 11 affecting the feeding and discharging movement of the product 3, the sliding direction of the support column 111 can have a certain angle with the feeding and discharging direction of the product 3.

[0040] The support base 112 is fixed on the support column 112. The support base 112 is usually cantilevered and has a certain length. The support plate 113 is slidably connected to the support base 112 in the horizontal direction. For example, there are two or more guide rods fixed on the support plate 113. The support base 112 is provided with guide holes that are adapted to the guide rods. In addition, a position adjustment mechanism 117 for driving the support plate 113 to move is fixedly installed on the support base 112. For example, it is any device that can output linear motion in the horizontal direction, such as a cylinder, hydraulic cylinder, electric cylinder, or gear and rack transmission structure driven by a motor. Its output end is connected to the support plate 113.

[0041] The brush 114, cutter 115, and air nozzle 116 are all fixedly installed on the side of the support plate 113 away from the support base 112. The brush 114 and cutter 115 are both elongated and vertically arranged, with a length approximately equal to the height of the product 3. The cutter 115 can be a serrated blade. Multiple air nozzles 116 are arranged vertically at intervals, with an arrangement range also approximately equal to the height of the product 3. The blowing angle and gas pressure of different air nozzles 116 can be adjusted. For example, the air nozzle 116 can be configured as a universal bamboo-joint air nozzle, and each air nozzle 116 is equipped with a valve for adjusting the blowing flow and pressure. Alternatively, the air nozzles 116 can be integrated into a single composite nozzle. Thus, when the side film cutting mechanism 11 approaches the product 3, the brush 114 can press the side film on the product 3 firmly, preventing it from loosening. The cutter 115 can cut the side film wrapped around the product 3, and the air nozzle 116 can maintain the adhesion of the cut side film to the product 3 through its ejected airflow. Typically, an air supply device 12, such as a pump, air compressor, or high-pressure air tank, is also installed on the base 101, which is connected to each air nozzle 116 via pipelines (specifically, flexible hoses). A film-cutting drive mechanism 13 is fixedly installed on the base 101. This side-cutting mechanism 13 drives the side-cutting mechanism 11 to move, allowing the side-cutting mechanism 11 to change its distance from the product 3 on the turntable 2, so that the cutting blade 115 can cut the side film when it approaches the product 3. The specific structure of the film-cutting drive mechanism 13 depends on the movement of the support column 111 relative to the base 101. For example, when the support column 111 is rotatably connected to the base 101, the film-cutting drive mechanism 13 is configured as a motor, with its motor shaft connected to the support column 111 via a gear transmission structure. When the support column 111 is slidably connected to the base 101, the film-cutting drive mechanism 13 is configured as any device capable of outputting linear motion in the horizontal direction, such as a cylinder, hydraulic cylinder, electric cylinder, or a gear and rack transmission structure driven by a motor.

[0042] It is easy to understand that the side film may loosen during the winding process. Therefore, in this embodiment, a composite nozzle 14 is also installed on the mounting wall panel 201. The composite nozzle 14 is used to provide airflow to the product 3 so that the free end of the side film can adhere to the side wall of the product 3 during the winding process. At this time, the shaft to which the turntable 2 belongs can be configured as hollow, and a rotary joint for supplying air to the composite nozzle 14 is arranged based on the hollow hole of the shaft. The rotary joint is connected to the air supply device 12 mentioned above through a pipeline. At this time, the composite nozzle 14 rotates together with the turntable 2. Therefore, the composite nozzle 14 can always blow towards the free end of the side film. In this case, the air pressure requirement is not high, and the blowing efficiency is high. The air path control is simple, the cost is low, and the noise is low. Of course, in other preferred embodiments, the composite nozzle 14 can also be fixedly installed on the frame 1. The composite nozzle 14 is connected to the air supply device 12 mentioned above through a pipeline. In this case, the composite nozzle 14 does not rotate with the turntable 2. There is more than one composite nozzle 14, which is arranged in a circle around the turntable 2. In this way, during the rotation of the turntable 2, the free end of the side film can be blown by each composite nozzle 14 at some specific positions, so that the free end of the side film can be attached to the side wall of the product 3. In this case, the composite nozzle 14 is far away from the product, and precise blowing is required. It has high requirements for air pressure, high cost, and high noise.

[0043] In this embodiment, the top film winding device includes a top film traction rod 19, a top film clamping component 20, a top film roll 21, a traction rod drive mechanism 22, a top film cutting mechanism 23, a height drive mechanism 24, and a height and position detection module 25, all mounted on the frame 1.

[0044] The top film traction rod 19 is specifically arranged on the frame body 103. It is slidably connected by a slide rail slider or a slider groove structure. The top film traction rod 19 slides in the horizontal plane, and the sliding direction of the top film traction rod 19 is approximately perpendicular to the feeding and discharging direction of the product 3. Furthermore, the length direction of the top film traction rod 19 itself is approximately parallel to the feeding and discharging direction of the product 3.

[0045] The top film clamping component 20 is fixedly installed on the top film traction rod 19. The top film clamping component 20 is used to clamp a section of the top film covering the top of the product 3. For example, the top film clamping component 20 is a pneumatic gripper or an electric gripper. Usually, there are two or more top film clamping components 20 and they are installed at intervals along the length direction of the top film traction rod 19.

[0046] The top film roll 21 is used to release the top film that covers the top of the product 3. A horizontally arranged crossbar is fixed on the frame 1, parallel to the feeding and discharging direction of the product 3. The structure of the top film roll 21 is the same as that of the side film roll 8. The top film roll 21 is fitted onto the crossbar, allowing it to rotate freely while on the crossbar, releasing the top film during rotation. It is easy to understand that when the crossbar and the top film traction rod 19 are not at the same height (for example, when the crossbar is fixed to the column 102), rollers are correspondingly installed on the frame 1 to guide the top film's direction, so that the top film released from the top film roll 21 can be pulled to the top film traction rod 19 and then clamped by the top film clamping member 20. Of course, the top film clamping member 20 can also release the clamped top film.

[0047] The traction rod drive mechanism 22 is fixedly installed on the frame body 103. It is used to drive the top film traction rod 19 to slide on the frame body 103. When the top film clamping member 20 clamps the top film, the traction rod drive mechanism 22 drives the top film traction rod 19 to slide on the frame body 103, which can pull the top film out and unfold it above the product 3.

[0048] In this embodiment, the traction rod drive mechanism 22 includes two chain drive structures, which are parallel to each other and arranged at intervals along the feeding and discharging direction of the product 3. Each chain drive structure includes two sprockets and a chain wound between the two sprockets. The sprockets are rotatably connected to the frame body 103, and the length direction of the chain is parallel to the sliding direction of the top film traction rod 19. The two ends of the top film traction rod 19 are respectively fixedly connected to the chains in the two chain drive structures. The traction rod drive mechanism 22 also includes a traction motor, which is fixed to the frame body 103. The traction motor is connected to the shaft of the sprocket in one of the chain drive structures, and the shaft is also connected to the corresponding sprocket in the other chain drive structure. Thus, when the traction motor is working, it can drive the two chain drive structures to rotate synchronously in the same direction, thereby causing the top film traction rod 19 to slide back and forth on the frame body 103.

[0049] Of course, in other preferred embodiments, the traction rod drive mechanism 22 can also be any device capable of outputting linear motion in the horizontal direction, such as a cylinder, hydraulic cylinder, electric cylinder, or gear and rack transmission structure driven by a motor, and its output end is fixedly connected to the top membrane traction rod 19.

[0050] The top film cutting mechanism 23 is mounted on the frame body 103 and located on the path of the top film. When the top film clamping member 20 on the top film traction rod 19 clamps the top film and moves it away from the top film roll 21 until the top of the product 3 is completely covered by the top film, the top film cutting mechanism 23 on the frame body 103 can cut the top film from the root. The "root" refers to the side of the frame body 103 near the top film roll 21, so that the cut top film has a size that can cover the product 3.

[0051] In this embodiment, the top film cutting mechanism 23 includes a top cutter 231 slidably connected to the frame body 103 and a top cutter drive mechanism 232 fixedly mounted on the frame body 103 for driving the top cutter 231 to move. The top cutter 231 moves in a direction perpendicular to the top film traction rod 19. The top cutter drive mechanism 232 can be any device capable of outputting linear motion in the horizontal direction, such as a pneumatic cylinder, hydraulic cylinder, electric cylinder, or a gear and rack transmission structure driven by a motor. Thus, when the top cutter 231 moves, it can cut the top film. Simultaneously with the top film being cut, the top film clamping member 20 releases the top film, and the cut top film falls and covers the top of the product 3, achieving the top wrapping operation of the product 3.

[0052] It is easy to understand that if the frame body 103 is too high above the top of the product 3, the top film may deviate due to the excessive falling distance, making it difficult to completely cover the top of the product 3.

[0053] Therefore, in this embodiment, the frame body 103 is slidably connected to the column 102 in a vertical direction. A height driving mechanism 24 is fixedly installed on the base 101 or the column 102. For example, it is any device that can output linear motion in a vertical direction, such as a cylinder, hydraulic cylinder, electric cylinder, or gear and rack transmission structure driven by a motor. Its output end is fixed on the frame body 103.

[0054] Meanwhile, a height and position detection module 25 for detecting the height and position information of product 3 is also fixed on the rack 1 (e.g., on the rack body 103).

[0055] It is easy to understand that when product 3 is completely wrapped in the side film and the turntable 2 stops rotating, the gap between the side film and product 3 may not be sufficient for the grippers 92 of the side film clamping mechanism 9 to extend. Therefore, the turntable 2 can be rotated slightly in the opposite direction to allow the side film to loosen and create a gap, so that the grippers 92 of the side film clamping mechanism 9 can extend between the side film and product 3. Therefore, as Figure 1As shown, the turntable 2 is also equipped with a conveying device 15 for transporting products, such as a roller conveyor, to carry the products. This roller conveyor can be used for loading and unloading products 3. In addition, when the product 3 is fully wrapped by the side film and the turntable 2 stops rotating, the conveying device 15 can still move the product 3, thereby loosening the side film and creating a gap between the side film and the product 3, so that the grippers 92 of the side film clamping mechanism 9 can extend in.

[0056] Or such as Figure 2 As shown, it also includes a movable rod 16, which is slidably connected to a slide rail arranged on the ground (or base 101). The movement direction of the movable rod 16 is parallel to the product's feeding and discharging direction. In addition, a movable rod drive component for driving the movement of the movable rod 16 is fixed on the ground (or base 101), such as a cylinder, hydraulic cylinder, electric cylinder, or any device capable of outputting linear motion in the horizontal direction, such as a gear and rack transmission structure driven by a motor. Thus, after the product has completed the side film winding, the movable rod 16 applies a pushing force to the side film connected between the side film roll 8 and the product 3, which can loosen the side film, thereby creating a margin between the side film and the product 3 that allows the gripper 92 of the side film clamping mechanism 9 to extend into.

[0057] The film winding process of a film winding device provided in this embodiment of the utility model is as follows:

[0058] When product 3 needs to be wrapped with film, the side film clamping mechanism 9 is first raised to the top surface of the turntable 2 by the film clamping lifting mechanism 10, and then the material roll support 6 is raised and lowered by the lifting drive mechanism 7 so that the side film roll 8 and the side film clamping mechanism 9 are at approximately the same height.

[0059] The free end of the side film released from the side film roll 8 is clamped by the side film clamping mechanism 9.

[0060] Place product 3 onto turntable 2;

[0061] The height and position detection module 25 detects the height and position information of product 3;

[0062] The height drive mechanism 24 drives the frame body 103 to move up and down, so that the distance between the frame body 103 and the top of the product 3 is within the required range;

[0063] When the equipment is used for the first time, the top film unwound from the top film roll 21 is manually pulled out and pulled to the top film traction rod 19. Then the top film clamping component 20 clamps the free end of the top film. The traction rod driving mechanism 22 drives the top film traction rod 19 to move away from the top film roll 21 until the top film completely covers the top space of the product 3.

[0064] The top film is cut at the root by the top film cutting mechanism 23, and then the top film clamping member 20 releases the free end of the top film. The cut top film falls and covers the top of the product 3, thus completing the top wrapping operation of the product 3. It is easy to understand that before the top film clamping member 20 releases the free end of the top film, the cut top film can also be moved by the traction rod drive mechanism 22 and the top film traction rod 19 to better cover the top of the product 3, thus completing the top film covering of the product 3.

[0065] The turntable 2 is rotated by the turntable drive mechanism 5, so that the side film wraps around the product 3 and the free end of the side film is tightly wrapped.

[0066] The side film clamping mechanism 9 releases the free end of the side film and is driven down to below the top surface of the turntable 2 by the film clamping lifting mechanism 10; after the side film clamping mechanism 9 releases the free end of the side film, it blows air into the free end of the side film through the nozzle 14 so that it always adheres to the side of the product 3.

[0067] The turntable 2 continues to rotate through the turntable drive mechanism 5. While the turntable 2 is rotating, the material roll support 6 is raised and lowered through the lifting drive mechanism 7 until the product 3 is completely wrapped by the side film. Then the rotation of the turntable 2 stops. At the same time, the top film covering the top of the product 3 can also be wrapped tightly by the side film.

[0068] The side film clamping mechanism 9 is raised above the top surface of the turntable 2 by the film clamping lifting mechanism 10. The conveying device 15 on the turntable 2 drives the product 3 to move. The moving rod 16 moves along the feeding and discharging direction of the product 3, thereby pulling the side film and leaving a margin between the side film and the product 3 for the side film clamping mechanism 9 to work. Then the side film is clamped by the side film clamping mechanism 9.

[0069] The side film cutting mechanism 11 is driven by the film cutting drive mechanism 13 to approach the product 3. The side film cutting mechanism 11 cuts the side film, completing the side film winding of the product 3. Then the side film clamping mechanism 9 and the side film cutting mechanism 11 are reset.

[0070] Normally, when cutting the side film, the side film clamping mechanism 9 holds the side film closer to the side film roll 8 than the side film cutting mechanism 11 cuts the side film. In this way, after the side film is cut, the side film clamping mechanism 9 can still hold the free end of the side film, which is convenient for the side film winding of subsequent products.

[0071] It is easy to understand that when winding the side film, product 3 is divided into three areas in the height direction: lower, middle and upper. As the material roll support 6 moves vertically, the lower area of ​​product 3 is wound at 50% speed for 4-5 turns, the middle area at 70% speed for 2-3 turns, and the upper area at 70% speed for 3-4 turns. This can maintain the stability of the side film winding of product 3, while also saving the amount of side film used and improving production efficiency.

[0072] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
