DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, 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 intended to limit the present invention.

[0024] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0025] like Figure 1 and Figure 2 FIG. 1 is a diagram showing an automatic bag packaging device according to an embodiment of the present invention, the device comprising:

[0026] A base 1 is provided with a first conveyor belt 4 and a second conveyor belt 5, which are 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 provided on the base 1, and an image acquisition device 7 is fixedly mounted 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.

[0027] A third conveyor belt 11 and a fourth conveyor belt 12 are also fixedly mounted on the base 1. Film edge sealing mechanisms are provided at both ends of the third conveyor belt 11 for sealing the bags with a film.

[0028] The base 1 is located at the end of the fourth conveyor belt 12 away from the third conveyor belt 11 and is provided with a film opening mechanism for cleaning the film around the luggage roller;

[0029] A hot air gun is provided on the base 1 for heat shrinking the film.

[0030] In the embodiment of the present invention, at airports or other places where items need to be stored, bags are generally protected by laminating. However, the efficiency of manual laminating is low, which affects the efficiency of transportation and handling. When laminating is performed by this 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. The bags are moved to the vicinity below the image acquisition device 7, and the image acquisition device 7 is used to capture 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 so that the bags can be rolled. 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 sets 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, causing 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 results of the image acquisition device 7, the film opening mechanism is controlled to clean the film near the roller, and 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.

[0031] 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 mounted on the base 1, and two sets of core shafts are rotatably provided on the second bracket 8, and the two sets of core shafts are respectively used to install the upper feed roller 9 and the lower feed roller 10, and the core shaft is connected to the second bracket 8 through a damping bearing, and the damping bearing is used to provide tensioning force. A side bracket is also fixedly mounted on the base 1, and an upper guide rod 22 and a lower guide rod 23 are fixedly mounted 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, and two groups of guide rollers 20 are rotatably provided on the extension bracket. The guide rollers 20 are The spiral roller and the extension bracket are also rotatably provided with two groups of crimping rollers 21, which are used to crimp the upper and lower layers of film into one. A third bracket 15 is fixedly installed on the base 1, and a plurality of first telescopic rods 16 are symmetrically arranged on the third bracket 15. The first telescopic rod 16 is divided into an upper telescopic rod and a lower telescopic rod. The upper telescopic rod and the lower telescopic rod are arranged opposite to each other. The first crimping plate 24, the cutting blade 25 and the 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. The third crimping plate 27, the cutting groove 28 and the 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.

[0032] In this embodiment, when the bag is wrapped with film, the starting position of the bag 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 bag can be determined based on the starting position of the bag and the running direction and time of each conveyor belt. When the bag enters the third conveyor belt 11, the ends and edges of the two layers of film are connected, and the bag drives the film to move synchronously. At this time, the two groups of film that have not yet been connected are respectively wound out from the upper feed roller 9 and the lower feed roller 10, and the upper feed roller 9 is rotated. The upper film passes under the upper guide rod 22, and the film on the lower feed roller 10 is located above the third conveyor belt 11. The two layers of film will pass through the gap between the upper guide rod 22 and the end of the lower guide rod 23 synchronously, and then the edge of the film will pass through the gap between the guide rollers 20. The guide rollers 20 press the two groups of films together, and the film drives the guide rollers 20 to rotate. The guide rollers 20 are spiral structures. During their rotation, they will drive the film to move to both sides to achieve lateral tensioning of the film. When the films that are tightly attached pass through the gap between the pressing rollers 21, they will be connected together. Specifically, the pressing rollers 21 can be connected by pressure or by heat welding. If heat welding is used, the corresponding film edges need to be thickened to facilitate connection. The edges of the film can also be connected by gluing, which will not be described here. In this way, the luggage will be covered with two layers of film, upper and lower. When the film passes through the third bracket 15, the upper telescopic rod and the lower telescopic rod extend synchronously, and the first pressing plate 24 is abutted against the third pressing plate 27, and the second pressing plate 26 is abutted against the fourth pressing plate 29. High-pressure pressing, welding, or other connection methods can be used here. The cutting blade 25 cooperates with the cutting groove 28 to cut the film. By sealing and cutting the film at both ends of the luggage, the luggage will be completely wrapped by the film. At this time, heat drying is used to make the film close to the outer wall of the box; by setting a damping spring, it can be ensured that the film has a stable tension in the length direction to avoid wrinkles in the film and affect the coating effect.

[0033] like 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, the fourth bracket 17 is fixedly mounted on the base 1, the fourth bracket 17 is fixedly mounted with a second telescopic rod 18, the second telescopic rod 18 is fixedly mounted with a connecting seat, the connecting seat is fixedly mounted with an electromagnet 31, two ends of the electromagnet 31 are fixedly provided with two groups of guide square rods 34, the sliding sleeve on the guide square rod 34 is provided with a telescopic sleeve 33, the telescopic sleeve 33 is fixedly connected to a mounting seat 32, the mounting seat 32 is fixedly connected to a heating ring 30 through a short bracket, the telescopic sleeve 33 is fixedly mounted with a magnetic block 36, the magnetic poles of the two groups of magnetic blocks 36 on the side close to each other are opposite, and a spring 35 is provided between the two groups of mounting seats 32 and the connecting seat.

[0034] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown in FIG. 1 , as a preferred embodiment of the present invention, the width of the ring body gradually decreases downward along the vertical direction, with the width being the smallest on the side close to the base 1 and the width being the largest on the side away from the base 1 .

[0035] In this embodiment, the distance between the rollers of the bag is determined by the image acquisition device 7, thereby controlling the electromagnet 31 to be energized, and the electromagnet 31 is used to generate a magnetic field. Since the magnetic poles of the two sets of magnetic blocks 36 are opposite on the side close to each other, the two sets of magnetic blocks 36 can be synchronously repelled or attracted, thereby adjusting the distance between the two sets of mounting seats 32, so that the distance between the two sets of mounting seats 32 is equal to the distance between the rollers on the bag in the width direction of the bag. As the fourth conveyor belt 12 moves, the rollers on the bag enter the heating ring 30, and the heating ring 30 generates heat to heat the rollers. The film around the wheel is cut, and the film around the roller is further contracted to fit tightly against the bag, leaving only the roller exposed. When constructing a three-dimensional model of the bag, the distance between the rollers on the bag can be known, so that the upper and lower pairs of rollers can be de-filmed twice by controlling the extension and retraction of the second telescopic rod 18. The distance between the mounting seats 32 can also be changed by using a screw and a threaded sleeve, and the effect is the same, so it will not be repeated here. Due to the different widths of the ring body, the film near the top is cut first and flipped downward under the action of its own weight, which can prevent the film from adhering to the roller.

[0036] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, as a preferred embodiment of the present invention, in the process of packaging luggage, multiple image acquisitions are performed by an image acquisition device, and modeling is performed based on the acquired luggage images to construct a three-dimensional model of the luggage. The size information and posture information of the luggage are determined based on the three-dimensional model of the luggage, and the posture of the luggage is adjusted based on the posture information of the luggage, so that the edge of the luggage remains parallel or perpendicular to the conveying direction of the first conveyor belt 4.

[0037] In this embodiment, when a bag is placed on the first conveyor belt 4 and the second conveyor belt 5, the image acquisition device can capture images of the bag from different angles by changing the position of the bag. The images are then processed using a Structure from Motion (SfM) algorithm or a deep learning algorithm to construct a three-dimensional model of the bag. The width, length, and distance between the rollers of the bag can be extracted from the three-dimensional model, and the relative positional relationship between the bag and the conveyor belt, such as whether it is tilted, can also be determined. The bag's posture is adjusted based on the posture information of the bag. When the first conveyor belt 4 and the second conveyor belt 5 move synchronously in the same direction and at a constant speed, the bag can be driven forward or backward. When the first conveyor belt 4 and the second conveyor belt 5 move synchronously in opposite directions and at a constant speed, the bag 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 bag can be driven to move toward the first conveyor belt 4 or the second conveyor belt 5 to achieve posture adjustment of the bag.

[0038] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, after the posture adjustment of the luggage is completed, the luggage is moved to the bottom of the image acquisition device 7 through the cooperation of the first conveyor belt 4 and the second conveyor belt 5, and a group of overhead images are acquired. The overhead images are processed to identify the width between the rollers of the luggage, and the film opening mechanism is adjusted based on the width between the rollers.

[0039] In this embodiment, the distance between the luggage rollers can also be directly obtained based on the three-dimensional model.

[0040] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, a material guide plate 19 is fixedly provided on one side of the base 1 close to the fourth conveyor belt 12 .

[0041] In this embodiment, the material guide plate 19 can ensure that the bags are in an upright state after being packed, and does not require workers to turn them over, thereby reducing labor intensity.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
