Description

Technical Field

[0001] This invention relates to the field of material handling equipment technology, and more specifically to a rope cutting and winding mechanism for a pack unpacking machine. Background Technology

[0002] Lightweight materials typically require compression and baling using baling or strapping machines before transport, significantly reducing transport space. Once the bundled materials are in place, they need to be unbundled during production, meaning the binding ropes need to be removed. Currently, manual unbundling is the most common method, requiring manual rope cutting and pulling, which wastes significant manpower and poses safety hazards. This method is increasingly failing to meet the requirements of modern production and therefore needs improvement.

[0003] To address the aforementioned technical problems, the applicant previously filed a patent application (application number CN202422732588.1) entitled "A Rope Removal Mechanism for Bundled Materials." This patent enables automatic rope removal from bundled materials, extracting the cut rope from the bundled material, thus completing the automatic rope cutting and removal operation without manual intervention, significantly improving the efficiency of rope removal from bundled materials. However, in actual use, it was found that because the ropes binding the materials are relatively long, during the actual rope removal process, the cut rope is prone to hitting other equipment or operators in the factory, posing a potential safety risk. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a rope cutting and winding mechanism for a pack unpacking machine, which can automatically untie the ropes from bundled materials and wind up the ropes after they are cut, thus eliminating potential safety risks.

[0005] To achieve the above technical solution, the present invention provides a rope cutting and winding mechanism for a pack unpacking machine, comprising: a frame, on which a transverse guide rail is mounted, and on which a rope cutting mechanism and a rope winding mechanism movable along the transverse guide rail are mounted, the rope winding mechanism comprising: a rope winding moving frame, which is mounted on the transverse guide rail via a second transverse moving module, a longitudinally driven sliding cylinder is mounted on the rope winding moving frame, a movable mounting seat is mounted on the telescopic shaft of the sliding cylinder, a rope winding box is mounted at the bottom of the movable mounting seat, a vertically downward-arranged rope winding motor is mounted inside the rope winding box, a turntable is mounted on the output shaft of the rope winding motor, two downward-extending and symmetrically arranged rope winding rods are mounted at the bottom of the turntable, a horizontally arranged rope winding detection cylinder is mounted at the bottom of the rope winding box, and a material sensor is mounted on the telescopic shaft of the rope winding detection cylinder.

[0006] In the above technical solution, during actual operation, when the bundled material is conveyed between the rope cutting mechanism and the rope winding mechanism, the distance between the rope cutting mechanism and the bundled material is first sensed by sensors installed in the rope cutting mechanism and the rope winding mechanism. Then, the distance between the rope cutting mechanism and the bundled material is adjusted by the lateral movement module. After the distance between the rope cutting mechanism and the bundled material (with the bundled material located in the middle of the rope cutting mechanism and the rope winding mechanism) is adjusted, the rope cutting mechanism and the rope winding mechanism move simultaneously from top to bottom. The rope cutting mechanism cuts the rope of the bundled material, while the sliding cylinder in the rope winding mechanism drives the moving mounting base to move... The rope winding box and the rope winding rod installed on the rope winding box move downwards, gathering the synchronously cut ropes together. Then, the rope winding motor drives the turntable to rotate the rope winding rod, winding the cut ropes neatly. This prevents the cut ropes from hitting other equipment or operators in the factory, eliminating potential safety risks. After the ropes are wound, the sliding cylinder drives the movable mounting base to reset. Then, the second lateral movement module drives the rope winding frame to move to the rope recovery station. The rope winding motor drives the turntable to rotate in the opposite direction, unloading the rope wound on the rope winding rod. Finally, the above operation is repeated.

[0007] Preferably, the bottom of the rope winding box is equipped with three downward-extending rope support brackets, and the bottom of the three rope support brackets are connected by an arc-shaped rope support plate. In actual operation, by setting the rope support brackets and the arc-shaped rope support plate, the rope can be prevented from flying around during the winding process, further ensuring the safety of operation during the winding process.

[0008] Preferably, the left and right sides of the rope winding box are each provided with an outwardly extending cylinder mounting plate. A downwardly vertically positioned rope-pressing cylinder is mounted on the cylinder mounting plate, and a rope-blocking pressure plate is mounted on the telescopic shaft of each of the two rope-pressing cylinders. The rope-blocking pressure plate is located below the turntable. In actual operation, the rope-pressing cylinders can drive the rope-blocking pressure plate to move up and down. The rope-blocking pressure plate serves two purposes: firstly, it presses down and collects the cut rope during the rope-cutting process; secondly, it prevents the cut rope from getting tangled on the turntable or motor.

[0009] Preferably, a second guide rod is installed vertically upward on the rope-blocking pressure plate, and a guide rod sleeve is installed on the cylinder mounting plate. The bottom of the second guide rod is fixed to the rope-blocking pressure plate, and the top of the second guide rod is inserted longitudinally into the guide rod sleeve on the cylinder mounting plate. This ensures that the rope-blocking pressure plate moves vertically up and down when the rope-pressing cylinder drives it to move.

[0010] Preferably, the rope cutting mechanism includes a rope cutting moving frame, which is connected to a transverse guide rail via a first transverse moving module. A longitudinal driving component is mounted on the rope cutting moving frame, a sliding mounting column is mounted on the longitudinal driving component, and the rope cutting component is mounted at the bottom of the sliding mounting column. In actual operation, the longitudinal driving component can drive the rope cutting component to move up and down, and the rope cutting component contacts the bundled material to cut the rope on the bundled material.

[0011] Preferably, the longitudinal drive assembly includes a mounting base installed on the rope cutting moving frame, a longitudinal moving slide rail mounted on the bottom of the mounting base, a sliding mounting column mounted on the longitudinal moving slide rail, and a longitudinal drive motor mounted on the mounting base and connected to the longitudinal moving slide rail. In actual operation, the longitudinal drive motor can drive the sliding mounting column to move up and down on the longitudinal moving slide rail, thereby controlling the vertical position of the cutting assembly mounted on the sliding mounting column.

[0012] Preferably, the rope cutting assembly includes a rope cutting drive motor mounted at the bottom of the sliding mounting post, and a cutting wheel is mounted on the output shaft of the rope cutting drive motor. In actual operation, the cutting wheel is driven to rotate at high speed by the rope cutting drive motor to cut the binding rope.

[0013] Preferably, a rope-cutting detection cylinder is installed on the sliding mounting column above the rope-cutting assembly, and a pressure sensor is installed on the telescopic shaft of the rope-cutting detection cylinder. In actual operation, when it is necessary to confirm the distance between the rope-cutting mechanism and the bundled material, the rope-cutting detection cylinder can drive the pressure sensor forward, and then the first lateral movement module drives the entire rope-cutting moving frame to approach the bundled material. When the pressure sensor contacts the surface of the bundled material, the distance between the rope-cutting mechanism and the bundled material can be determined, and then the cutting assembly can be driven to cut the rope on the surface of the bundled material.

[0014] Preferably, a vertically upward-oriented first guide rod is mounted on the movable mounting base, and a guide rod sleeve is mounted on the rope winding frame. The bottom of the first guide rod is fixed to the movable mounting base, and the top of the first guide rod is inserted longitudinally into the guide rod sleeve. By setting the first guide rod, it is ensured that the movable mounting base moves vertically up and down when driven by the sliding cylinder.

[0015] The beneficial effects of the rope cutting and winding mechanism of the unpacking machine provided by this invention are as follows: The rope cutting and winding mechanism of this unpacking machine is reasonably designed and highly automated, enabling automatic rope untying of bundled materials, significantly improving the rope untying efficiency, and can be wound up after the rope is cut, eliminating potential safety risks. In actual operation, the rope cutting mechanism and the rope winding mechanism can move on the transverse guide rail respectively through the first transverse moving module and the second moving module. When the bundled material is conveyed between the rope cutting mechanism and the rope winding mechanism, the distance between the rope cutting mechanism and the bundled material is first sensed by sensors installed in the rope cutting mechanism and the rope winding mechanism. Then, the distance between the rope cutting mechanism and the bundled material is adjusted by the transverse moving module. After the distance between the rope cutting mechanism and the bundled material (the bundled material is located in the middle of the rope cutting mechanism and the rope winding mechanism) is adjusted, the rope cutting mechanism and the rope winding mechanism move from top to bottom simultaneously, wherein the rope cutting mechanism cuts the rope of the bundled material. During operation, the sliding cylinder in the rope winding mechanism drives the movable mounting base to move the rope winding box and the rope winding rod installed on the rope winding box downwards, gathering the synchronously cut ropes together. Then, the rope winding motor drives the turntable to rotate the rope winding rod, winding the cut ropes neatly. This prevents the cut ropes from hitting other equipment or operators in the factory, eliminating potential safety risks. After the ropes are wound, the sliding cylinder drives the movable mounting base to reset, and then the second lateral movement module drives the rope winding frame to move to the rope recovery station. The rope winding motor drives the turntable to rotate in the opposite direction, unloading the rope wound on the rope winding rod. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] Example: A rope cutting and winding mechanism for a pack unpacking machine.

[0025] Reference Figures 1 to 6As shown, a rope cutting and winding mechanism for a pack unpacking machine includes: a frame 1, on which a transverse guide rail 2 is mounted, and a rope cutting mechanism 3 and a rope winding mechanism 4 are mounted on the transverse guide rail 2. The rope cutting mechanism 3 includes a rope cutting moving frame 31, which is connected to the transverse guide rail 2 via a first transverse moving module 32. In actual operation, the first transverse moving module 32 can drive the rope cutting moving frame 31 to move on the transverse guide rail 2. A longitudinal driving assembly is mounted on the rope cutting moving frame 31, and a sliding mounting column 36 is mounted on the longitudinal driving assembly. The longitudinal driving assembly includes a mounting base 33 mounted on the rope cutting moving frame 31, and a longitudinal moving slide rail 35 is mounted at the bottom of the mounting base 33. The sliding mounting post 36 is mounted on the longitudinal moving slide rail 35, and the longitudinal drive motor 34 is mounted on the mounting base 33 and connected to the longitudinal moving slide rail 35. In actual operation, the longitudinal drive motor 34 can drive the sliding mounting post 36 to move up and down on the longitudinal moving slide rail 35, thereby controlling the up and down position of the cutting component mounted on the sliding mounting post 36. The rope cutting component is mounted at the bottom of the sliding mounting post 36. The rope cutting component includes a rope cutting drive motor 38 mounted at the bottom of the sliding mounting post 36. A cutting wheel 39 is mounted on the output shaft of the rope cutting drive motor 38. In actual operation, the rope cutting drive motor 38 drives the cutting wheel 39 to rotate at high speed to cut the binding rope. A rope-cutting detection cylinder 37 is installed on the sliding mounting column 36 above the rope-cutting assembly. A pressure sensor 310 is installed on the telescopic shaft of the rope-cutting detection cylinder 37. In actual operation, when it is necessary to confirm the distance between the rope-cutting mechanism 3 and the bundled material, the pressure sensor 310 can be pushed forward by the rope-cutting detection cylinder 37. Then, the first lateral moving module 32 drives the rope-cutting moving frame 31 to move closer to the bundled material. When the pressure sensor 310 contacts the surface of the bundled material, the distance between the rope-cutting mechanism 3 and the bundled material can be determined. Then, the cutting assembly can be driven to cut the rope on the surface of the bundled material.

[0026] The rope winding mechanism 4 includes a rope winding moving frame 41, which is mounted on the transverse guide rail 2 via a second transverse moving module 43. A longitudinally driven sliding cylinder 42 is mounted on the rope winding moving frame 41, and a movable mounting seat 44 is mounted on the telescopic shaft of the sliding cylinder 42. In actual operation, the sliding cylinder 42 can drive the movable mounting seat 44 to move up and down. A rope winding box 47 is mounted at the bottom of the movable mounting seat 44, and a vertically downward-oriented rope winding motor 416 is mounted inside the rope winding box 47. A turntable 415 is mounted on the output shaft of the rope winding motor 416, and two downward-extending and symmetrically arranged rope winding rods 412 are mounted at the bottom of the turntable 415. In actual operation, the rope winding motor 416 can drive the turntable 415 to rotate the two rope winding rods 412. The bottom of the rope winding box 47 is equipped with a rope winding detection cylinder 411 arranged horizontally in the transverse direction. A material sensor is installed on the telescopic shaft of the rope winding detection cylinder 411. In actual operation, when it is necessary to confirm the distance between the rope winding mechanism 4 and the bundled material, the material sensor can be pushed forward by the rope winding detection cylinder 411. Then, the second transverse moving module 43 drives the rope winding moving frame 41 to move closer to the bundled material. When the material sensor contacts the surface of the bundled material, the distance between the rope winding mechanism 4 and the bundled material can be determined.

[0027] Reference Figure 5 and Figure 6 As shown, the bottom of the rope winding box 47 is equipped with three downward-extending rope-collecting brackets 413. The bottom of the three rope-collecting brackets 413 is connected by an arc-shaped rope-collecting plate 414. In actual operation, by setting the rope-collecting brackets 413 and the arc-shaped rope-collecting plate 414, the rope can be prevented from flying around during the winding process, further ensuring operational safety during the winding process. Both the left and right sides of the rope winding box 47 are equipped with outward-extending cylinder mounting plates. Vertically downward-mounted rope-pressing cylinders 49 are mounted on the cylinder mounting plates. Rope-blocking pressure plates 48 are mounted on the telescopic shafts of the two rope-pressing cylinders 49, and the rope-blocking pressure plates 48 are located below the turntable 415. In actual operation, the rope-pressing cylinders 49 can drive the rope-blocking pressure plates 48 to move up and down. The rope-blocking pressure plates 48 serve two purposes: firstly, they can press down and collect the cut rope during the rope-cutting process; secondly, they can prevent the cut rope from getting tangled on the turntable 415 or the rope winding motor 416. A second guide rod 410 is installed vertically upward on the rope-blocking pressure plate 48, and a guide rod sleeve is installed on the cylinder mounting plate. The bottom of the second guide rod 410 is fixed on the rope-blocking pressure plate 48, and the top of the second guide rod 410 is inserted longitudinally into the guide rod sleeve provided on the cylinder mounting plate, which can ensure that the rope-pressing cylinder 49 drives the rope-blocking pressure plate 48 to move vertically up and down.

[0028] To further explain the present invention, the working steps of the present invention are explained as follows:

[0029] (1) The bundled material is conveyed to the area below between the rope cutting mechanism 3 and the rope winding mechanism 4.

[0030] (2) The longitudinal drive motor 34 in the rope cutting mechanism 3 drives the sliding mounting column 36 to move the rope cutting assembly and the rope cutting detection cylinder 37 downward. Then, the rope cutting detection cylinder 37 drives the pressure sensor 310 to push forward. The first lateral movement module 32 drives the rope cutting moving frame 31 to move closer to the bundled material. When the pressure sensor 310 contacts the surface of the bundled material, the first lateral movement module 32 stops moving, the longitudinal drive motor 34 drives the sliding mounting column 36 to reset upward, and the rope cutting detection cylinder 37 drives the pressure sensor 310 to retract and reset. At the same time, the sliding cylinder 42 in the rope winding mechanism 4 drives the movable mounting base 44 to move the rope winding box 47 and the rope winding detection cylinder 411 downward. Then, the rope winding detection cylinder 411 drives the material sensor to push forward. Then, the second lateral movement module 43 drives the rope winding moving frame 41 to move closer to the bundled material. When the material sensor contacts the surface of the bundled material, the second lateral movement module 43 stops moving, the sliding cylinder 42 drives the rope winding box 47 and the rope winding detection cylinder 411 to reset upward, and the rope winding detection cylinder 411 drives the material sensor to retract and reset.

[0031] (3) The first lateral movement module 32 in the rope cutting mechanism 3 drives the rope cutting moving frame 31 to move closer to the bundled material by 2-5cm, ensuring that the cutting wheel 39 can contact the rope on the surface of the bundled material. At the same time, the second lateral movement module 43 drives the winding moving frame 41 to move closer to the bundled material by 2-5cm, ensuring that the winding rod 412 can be inserted into the rope on the surface of the bundled material when it moves downward.

[0032] (4) The rope cutting drive motor 38 in the rope cutting mechanism 3 drives the cutting wheel 39 to rotate at high speed. Then, the longitudinal drive motor 34 drives the sliding mounting column 36 to move the cutting wheel 39 downward. During the downward movement, the cutting wheel 39 contacts multiple ropes on the surface of the bundled material to cut the ropes binding the material. At the same time, the sliding cylinder 42 in the rope winding mechanism 4 drives the movable mounting seat 44 to move the rope winding box 47 and the rope winding rod 412 downward. During the downward movement, the rope winding rod 412 presses down on the cut ropes. When all the ropes are cut, the rope winding motor 416 drives the turntable 415 to rotate the rope winding rod 412 to wind the cut ropes. This can prevent the cut ropes from hitting other equipment or operators in the factory and eliminate potential safety risks.

[0033] (5) After the rope is wound, the sliding cylinder 42 in the rope winding mechanism 4 drives the movable mounting base 44 to reset. Then, the second transverse moving module 43 drives the rope winding moving frame 41 to move to the rope recycling station. The rope winding motor 416 drives the turntable 415 to rotate in the opposite direction to unload the rope wound on the rope winding rod 412, thereby completing the entire process of rope disassembly, rope winding and rope unloading.

[0034] The rope cutting and winding mechanism of this unpacking machine is reasonably designed and highly automated, enabling automatic rope untying of bundled materials without human intervention. This significantly improves the efficiency of untying bundled materials. Furthermore, the rope can be wound up after being cut, eliminating potential safety risks.

[0035] The above description is only a preferred embodiment of the present invention, but the present invention should not be limited to the content disclosed in the embodiments and drawings. Therefore, any equivalent or modified embodiments made without departing from the spirit of the present invention shall fall within the protection scope of the present invention.
