Detailed Embodiments

[0015] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0016] The specific implementation of the present invention will be described in detail below in conjunction with specific embodiments.

[0017] As Figure 1 and Figure 2 shown, a kind of automatic luggage packaging equipment provided by an embodiment of the present invention, the equipment includes: A base 1, on which a first conveyor belt 4 and a second conveyor belt 5 are installed, driven by a first motor 2 and a second motor 3 respectively. The first conveyor belt 4 and the second conveyor belt 5 are arranged in parallel. A first bracket 6 is installed on the base 1, and an image acquisition device 7 is fixedly installed on the first bracket 6. The image acquisition device 7 is located directly above the first conveyor belt 4 and the second conveyor belt 5; A third conveyor belt 11 and a fourth conveyor belt 12 are also fixedly installed on the base 1. Film edge sealing mechanisms are arranged at both ends of the third conveyor belt 11 for packaging the luggage with film; At one end of the base 1 away from the third conveyor belt 11 of the fourth conveyor belt 12, a film opening mechanism is provided for cleaning the film around the luggage rollers; A hot air gun is arranged on the base 1 for heat shrinking the film.

[0018] In the embodiment of the present invention, at airports or other places where items need to be entrusted, bags are generally protected by laminating, but the efficiency of manual laminating is low, which affects the efficiency of transportation and handling. When laminating by the present device, the bags are directly placed on the first conveyor belt 4 and the second conveyor belt 5. At this time, the bags can be placed obliquely on the two sets of conveyor belts. The first conveyor belt 4 and the second conveyor belt 5 run synchronously in the same direction, and the bags are moved to the vicinity below the image acquisition device 7. The image acquisition device 7 is used to acquire images, thereby identifying the size and posture of the bags. According to the recognition result, the first conveyor belt 4 and the second conveyor belt 5 are controlled to cooperate, and the posture of the bags is changed to make the bags roll smoothly. The wheel axis is parallel to the conveying direction of the first conveyor belt 4. After the luggage is adjusted, it is conveyed to the third conveyor belt 11. The upper and lower groups of films are compounded on the periphery of the luggage through the film edge sealing mechanism. The coating is a heat-shrinkable film. During its further movement, the film is heated by a hot air drying gun to cause the film to shrink and tightly wrap around the periphery of the luggage. At this time, the rollers of the luggage are also covered and cannot be used. At this time, according to the recognition result of the image acquisition device 7, the film opening mechanism is controlled to clean the film near the roller, so that the roller is exposed for easy handling and movement; the third conveyor belt 11 is driven by the third motor 13, and the fourth conveyor belt 12 is driven by the fourth motor 14.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, as a preferred embodiment of the present invention, the film edge-sealing mechanism includes a second bracket 8, which is fixedly installed on the base 1. Two groups of mandrels are rotatably arranged on the second bracket 8. The two groups of mandrels are respectively used to install the upper feeding roller 9 and the lower feeding roller 10. The mandrels are connected to the second bracket 8 through damping bearings, and the damping bearings are used to provide tension. A side bracket is also fixedly installed on the base 1. An upper guide rod 22 and a lower guide rod 23 are fixedly installed on the side bracket. The upper guide rod 22 is located above the third conveyor belt 11, and the lower guide rod 23 passes through the middle of the third conveyor belt 11. A group of extension brackets are fixed on both sides of the side bracket. Two groups of guide rollers 20 are rotatably arranged on the extension brackets. The guide rollers 20 are spiral rollers. Two groups of crimping rollers 21 are also rotatably arranged on the extension brackets. The crimping rollers 21 are used to crimp the upper and lower layers of the film into one body. A third bracket 15 is fixedly installed on the base 1. A plurality of first telescopic rods 16 are symmetrically arranged on the third bracket 15. The first telescopic rods 16 are divided into upper telescopic rods and lower telescopic rods, and the upper telescopic rods and the lower telescopic rods are arranged oppositely. A first crimping plate 24, a cutting blade 25 and a second crimping plate 26 are fixedly installed on the telescopic end of the upper telescopic rod. The cutting blade 25 is installed between the first crimping plate and the second crimping plate 26. A third crimping plate 27, a cutting groove 28 and a fourth crimping plate 29 are fixedly installed on the telescopic end of the lower telescopic rod. The cutting groove 28 is located between the third crimping plate 27 and the fourth crimping plate 29.

[0020] In this embodiment, when the luggage is wrapped with a thin film, the starting position of the luggage is determined by the image acquisition device 7. Since the lengths and conveying speeds of all conveyor belts are known, the current position of the luggage can be determined according to the starting position of the luggage, the running directions and times of the respective conveyor belts. When the luggage enters the third conveyor belt 11, the ends and edges of the two layers of thin films are connected, and the luggage drives the thin film to move synchronously. At this time, the two groups of thin films that have not been connected are respectively wound out from the upper feeding roller 9 and the lower feeding roller 10. The thin film on the upper feeding roller 9 passes under the upper guide rod 22, while the thin film on the lower feeding roller 10 is located above the third conveyor belt 11. The two layers of thin films will synchronously pass through the gap between the ends of the upper guide rod 22 and the lower guide rod 23. Subsequently, the edges of the thin films will pass through the gaps between the guide rollers 20. The guide rollers 20 press the two groups of thin films together. The thin film drives the guide rollers 20 to rotate, and the guide rollers 20 are of a spiral structure. During their rotation, they will drive the thin film to move to both sides to achieve the transverse tension of the thin film. When the closely attached thin films pass through the gap between the crimping rollers 21, they will be connected together. Specifically, the crimping rollers 21 can be connected by pressure or by heat welding. If heat welding is used, the corresponding edges of the thin film need to be thickened for easy connection, or the edges of the thin film can be connected by bonding. This will not be elaborated here. Then the luggage will be wrapped by the upper and lower layers of thin films. When the thin film passes through the third bracket 15, the upper telescopic rod and the lower telescopic rod extend synchronously. The first crimping plate 24 abuts against the third crimping plate 27, and the second crimping plate 26 abuts against the fourth crimping plate 29. Here, high-pressure crimping can also be used, or welding can be used, or other connection methods can be used. The cutting blade 25 cooperates with the cutting groove 28 to cut off the thin film. By sealing and cutting the thin films at both ends of the luggage, the luggage will be completely wrapped by the thin film. At this time, by using the hot air drying method, the thin film can be made to closely adhere to the outer wall of the box; by setting the damping spring, a stable tension force can be ensured in the length direction of the thin film, preventing the thin film from wrinkling and affecting the film covering effect.

[0021] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, as a preferred embodiment of the present invention, the film opening mechanism includes a fourth bracket 17, which is fixedly installed on the base 1. A second telescopic rod 18 is fixedly installed on the fourth bracket 17. A connecting seat is fixedly installed on the second telescopic rod 18. An electromagnet 31 is fixedly installed on the connecting seat. Two sets of guiding square rods 34 are fixedly arranged at both ends of the electromagnet 31. A telescopic sleeve 33 is slidably sleeved on the guiding square rod 34. An installation seat 32 is fixedly connected to the telescopic sleeve 33. The installation seat 32 is fixedly connected to a heating ring 30 through a short bracket. A magnetic block 36 is fixedly installed on the telescopic sleeve 33. The magnetic poles of the two magnetic blocks 36 on the side close to each other are opposite. Springs 35 are arranged between the two installation seats 32 and the connecting seat.

[0022] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, the width of the ring body gradually decreases downward along the vertical direction, with the smallest width on the side close to the base 1 and the largest width on the side far from the base 1.

[0023] In this embodiment, the distance between the rollers of the luggage is determined by the image acquisition device 7, so as to control the energization of the electromagnet 31. The electromagnet 31 generates a magnetic field. Since the magnetic poles of the two magnetic blocks 36 on the side close to each other are opposite, the two magnetic blocks 36 can be synchronously repelled or attracted, realizing the adjustment of the distance between the two installation seats 32, so that the distance between the two installation seats 32 is equal to the distance between the rollers of the luggage in the width direction of the luggage. As the fourth conveyor belt 12 moves, the rollers on the luggage enter into the heating ring 30. The heating ring 30 generates heat to cut the film around the rollers and promotes the further shrinkage of the film around the rollers to tightly adhere to the luggage, only exposing the rollers. When constructing the three-dimensional model of the luggage, the distance between the rollers on the luggage can be obtained, so as to control the telescopic movement of the second telescopic rod 18 to perform the film removal treatment on the upper and lower pairs of rollers in two times; here, the distance between the installation seats 32 can also be changed by using a screw and a threaded sleeve, with the same effect, which will not be elaborated; due to the different widths of the ring body, the film near the upper part is cut first and turns downward under its own weight, which can prevent the film from adhering to the rollers.

[0024] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, as a preferred embodiment of the present invention, during the process of packaging the luggage, multiple image acquisitions are performed by an image acquisition device, modeling processing is performed based on the acquired luggage images, a three-dimensional model of the luggage is constructed, the size information and attitude information of the luggage are determined according to the three-dimensional model of the luggage, and the attitude of the luggage is adjusted according to the attitude information of the luggage, so that the edge of the luggage is parallel or perpendicular to the conveying direction of the first conveyor belt 4.

[0025] In this embodiment, when the luggage is placed on the first conveyor belt 4 and the second conveyor belt 5, by changing the position of the luggage, the image acquisition device can perform image acquisition on the luggage from different angles, and then use the Structure from Motion (SfM) algorithm or deep learning algorithm for processing to construct a three-dimensional model of the luggage. The width, length, and distance between the rollers of the luggage can be extracted from the three-dimensional model, and the relative position relationship between the luggage and the conveyor belt, such as whether it is tilted, can also be determined. According to the attitude information of the luggage, the attitude of the luggage is adjusted. When the first conveyor belt 4 and the second conveyor belt 5 move synchronously and in the same direction at a constant speed, the luggage can be driven forward or backward. When the first conveyor belt 4 and the second conveyor belt 5 move synchronously and in the opposite direction at a constant speed, the luggage can be driven to rotate in place. When the conveying speeds of the first conveyor belt 4 and the second conveyor belt 5 are different, the luggage can be driven to move towards the first conveyor belt 4 or the second conveyor belt to achieve the attitude adjustment of the luggage.

[0026] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, after the attitude adjustment of the luggage is completed, the luggage is moved to directly below the image acquisition device 7 through the cooperation of the first conveyor belt 4 and the second conveyor belt 5, a set of top-down images are acquired, the top-down images are processed, the width between the rollers of the luggage is identified, and the film opening mechanism is adjusted based on the width between the rollers.

[0027] In this embodiment, the distance between the luggage rollers can also be directly obtained from the three-dimensional model.

[0028] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, a guide plate 19 is fixedly provided on one side of the base 1 close to the fourth conveyor belt 12.

[0029] In this embodiment, setting the guide plate 19 can ensure that the luggage is in an upright state after being packaged, eliminating the need for manual flipping by workers and reducing labor intensity.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
