Description

Technical Field

[0001] This utility model relates to the technical field of logistics equipment, and in particular to an automatic box opener. Background Technology

[0002] In the process of packing boxes for logistics and express delivery, staff usually need to unfold the stacked boxes and seal the bottom of the boxes to facilitate subsequent packing. This requires a lot of manual labor for opening the boxes, which is costly and reduces the efficiency of opening the boxes, making it difficult to meet the needs of the express delivery industry for streamlined processing.

[0003] Existing box-opening equipment only processes a portion of the process and suffers from complex structures and poor adaptability. There is a lack of an automatic box-opening machine that can integrate and automate the entire process. Utility Model Content

[0004] In order to improve the problems in the process of unfolding folded cardboard boxes in the above-mentioned background art, this utility model provides an automatic carton opening machine.

[0005] The automatic box opener provided by this utility model adopts the following technical solution:

[0006] An automatic carton unpacking machine includes a conveying mechanism, an unfolding mechanism, and a folding mechanism. The conveying mechanism includes a track for conveying folded cartons, and a pusher plate is slidably mounted on the conveying track. The pusher plate abuts against stacked folded cartons and pushes them along the length of the conveying track. The unfolding mechanism includes a fixed frame installed at the end of the conveying track. A robotic arm that extends and retracts horizontally is mounted on the fixed frame. An adsorption plate is fixedly connected to the front end of the robotic arm. The adsorption plate adsorbs the side wall of the folded cartons. A swing plate is movably connected to one side of the adsorption plate. The swing plate is driven by a servo motor to swing horizontally. The swing plate abuts against the back wall of the cartons and pushes the folded cartons to unfold into a cylindrical shape. A sealing track is connected to one side of the fixed frame. The folding mechanism includes a bottom cover folding mechanism installed at the bottom of the fixed frame and a bottom side cover folding mechanism installed on the sealing track. A sealing mechanism for sealing the gap between the two bottom side covers of the cartons is also installed on the sealing track.

[0007] Preferably, the bottom cover folding mechanism includes a first folding plate movably disposed at the bottom of the fixed frame. The first folding plate is driven by a servo motor to swing upward. The first folding plate abuts against and pushes the bottom cover of the carton located on the rear side to bend inward. The bottom cover folding mechanism also includes a second folding plate inclinedly disposed at the front end of the sealing track. The second folding plate abuts against and pushes the bottom cover of the carton located on the front side to bend inward when the carton passes by.

[0008] Preferably, the bottom side cover folding mechanism includes two symmetrically arranged side folding plates, which are driven by a side folding servo motor to swing inward into the sealing track, pushing the two bottom side covers of the carton to bend inward.

[0009] Preferably, the sealing mechanism includes a tape reel, a pressing roller, and a cutting component installed sequentially along the sealing track. The tape reel outputs tape with the adhesive side facing upward along the carton conveying direction. The pressing roller is distributed on the carton conveying path. The cutting component includes cutting teeth and an electromagnetic push rod. The electromagnetic push rod drives the cutting teeth to move in a direction perpendicular to the tape and cut the tape.

[0010] Preferably, the bottom of the push plate is connected to a nut seat, which cooperates with a lead screw arranged along the length of the conveying track. The extended end of the lead screw is connected to a drive motor, and the drive motor drives the push plate to slide along the conveying track through the lead screw transmission.

[0011] Preferably, a group of photoelectric sensors is distributed along the carton processing path. The photoelectric sensor group is electrically connected to a controller installed outside the folding mechanism and triggers the actions of each mechanism.

[0012] Preferably, the adsorption plate is a vacuum adsorption plate, and the vacuum adsorption plate is connected to a vacuum generator through an air pipe.

[0013] In summary, this utility model has the following beneficial technical effects:

[0014] 1. This utility model designs an automatic carton opening machine. First, a conveying mechanism pushes a folded carton. The unfolding mechanism unfolds the folded carton with the help of a robotic arm and a swing plate. The end cap folding mechanism consists of two parts, which fold the bottom end cap and the bottom side cap respectively. Then, the sealing mechanism glues and seals the bottom of the carton. The cooperation of each mechanism realizes the automatic unfolding, bottom folding and tape sealing of the folded carton. The fully automated process saves costs, and the assembly line operation does not require manual intervention, thus improving the sealing efficiency.

[0015] 2. This utility model uses a combination of multiple mechanisms, which is highly adaptable. It can be disassembled and repaired individually, while the multiple mechanisms are linked and controlled to meet the needs of carton opening and subsequent production. Attached Figure Description

[0022] The following combination Figures 1-5 The present invention will be described in further detail below.

[0023] This utility model discloses an automatic box opener.

[0024] Reference Figure 1 , Figure 2 , Figure 3 An automatic box opener includes a conveying mechanism 1, an unfolding mechanism 2, and a folding mechanism 3.

[0025] The conveying mechanism 1 includes a conveying track 4 for conveying folded cartons. A pusher plate 5 is slidably disposed on the conveying track 4. The pusher plate 5 abuts against the stacked folded cartons and pushes them along the length of the conveying track 4.

[0026] The unfolding mechanism 2 includes a fixed frame 6 installed at the end of the track. A mechanical arm 7 that extends and retracts in the horizontal direction is installed on the fixed frame 6. An adsorption plate 8 is fixedly connected to the front end of the mechanical arm 7. The adsorption plate 8 is a vacuum adsorption plate. The adsorption plate 8 is connected to a vacuum generator through an air pipe. The vacuum generator is electrically connected to a controller 25 located outside the conveying mechanism 1. The adsorption surface of the adsorption plate 8 is provided with honeycomb-shaped adsorption holes. At the position of the adsorption holes, an adsorption force is formed on the side wall 26 of the carton. The adsorption plate 8 adsorbs the side wall 26 of the folded carton. A swing plate 9 is movably connected to one side of the adsorption plate 8. The swing plate 9 is driven by a servo motor to swing in the horizontal direction. The swing plate 9 abuts against the back wall 27 of the carton and pushes the folded carton to unfold into the cylindrical shape of the carton.

[0027] The fixing frame 6 is connected to the sealing track 10 on one side. The sealing track 10 includes conveyor belts on both sides, which are driven by motors. The folding mechanism 3 includes a bottom cover folding mechanism 11 installed at the bottom of the fixing frame 6 and a bottom side cover folding mechanism 12 installed on the sealing track 10. The sealing track 10 is also equipped with a sealing mechanism 13 for sealing the gap between the two bottom side covers 29 at the bottom of the carton.

[0028] Reference Figure 1 , Figure 3 , Figure 4 The bottom cover folding mechanism 11 includes a first folding plate 14 movably disposed at the bottom of the fixed frame 6. The first folding plate 14 is driven by a servo motor to swing upward. The first folding plate 14 abuts against and pushes the bottom cover 28 of the carton located on the rear side to bend inward. The bottom cover folding mechanism 11 also includes a second folding plate 15 inclinedly disposed at the front end of the sealing track 10. There is a height difference between the fixed frame 6 and the sealing track 10. When the carton passes by, the second folding plate 15 abuts against and pushes the bottom cover 28 of the carton located on the front side to bend inward.

[0029] Reference Figure 3 , Figure 5 The bottom side cover folding mechanism 12 includes two symmetrically arranged side folding plates 16. The side folding plates 16 are driven by a side folding servo motor to swing inward into the sealing track 10, pushing the two bottom side covers 29 of the carton to bend inward.

[0030] Reference Figure 1 , Figure 3 The sealing mechanism 13 includes a tape reel 17, a pressing roller 18, and a cutting component 19, which are installed sequentially along the sealing track 10. The tape reel 17 outputs tape with the adhesive side facing upward along the carton conveying direction. Multiple pressing rollers 18 are provided and distributed along the carton conveying path. The cutting component 19 includes cutting teeth 20 and an electromagnetic push rod 21. The electromagnetic push rod 21 drives the cutting teeth 20 to move in a direction perpendicular to the tape and cut the tape.

[0031] Reference Figure 1 The bottom of the push plate 5 is connected to the nut seat 22, which cooperates with the lead screw 23 set along the length of the track. The extended end of the lead screw 23 is connected to the drive motor, and the drive motor drives the push plate 5 to slide along the track through the lead screw 23.

[0032] Reference Figure 1 , Figure 3 A photoelectric sensor group 24 is distributed along the carton processing path. The photoelectric sensor group 24 includes a photoelectric output device and a photoelectric receiver. The photoelectric sensor group 24 is respectively set at the output end of the conveying mechanism 1, the unfolding mechanism 2, the entrance of the sealing track 10, the front side of the bottom cover folding mechanism 12, and the side of the cutting piece 19. The photoelectric sensor group 24 is electrically connected to the controller 25 installed outside the folding mechanism 3, and is used to detect the position of the carton and trigger the action of each mechanism.

[0033] The implementation principle of an automatic box opener according to this utility model embodiment is as follows:

[0034] The stacked folded cartons are placed on the conveyor track 4 of the conveyor mechanism 1 and continuously pushed by the pusher plate 5. When the photoelectric sensor 24 at the output end of the conveyor mechanism 1 detects the folded cartons, it triggers the extension of the robotic arm 7. The suction plate 8 at the front end of the robotic arm 7 adsorbs the side wall 26 of the cartons and moves the folded cartons out. The controller controls the servo motor to drive the swing plate 9. The swing plate 9 swings horizontally to push the back wall 27 of the cartons, unfolding the folded cartons into a cylindrical shape.

[0035] The carton is in an upright position. The bottom cover 28 of the carton is pushed inward by the bottom cover folding mechanism 11. The carton is fed in by the sealing track 10. The bottom cover folding mechanism 12 inside the sealing track 10 pushes the bottom cover 29 of the carton inward, so that all four sides of the bottom of the carton are bent.

[0036] The sealing mechanism 13 is used to seal the gap between the two bottom side covers 29 at the bottom of the carton, and the carton with the bottom sealed is output for subsequent packing processes.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
