Description

Technical Field

[0001] This invention relates to an automatic package transfer mechanism with a corrective and guiding function, and relates to the field of packaging machinery. Background Technology

[0002] With the gradual development of industrial technology, industrial production is constantly improving its production methods and raising the technological requirements. In existing packaging conveyor lines, from the moment materials are fed into the packaging bags to the actual conveying process, there are a series of actions targeting the bag openings. Packaging bags filled with material often experience problems such as bag opening misalignment and unevenness, which significantly impacts subsequent sewing processes. This requires constant manual intervention, greatly affecting packaging and conveying efficiency and also posing certain safety hazards. Summary of the Invention

[0003] This invention provides an automatic bag transfer mechanism with a correction and guide function to overcome the defects in the prior art where packaging bags will shift and be arranged unevenly during transportation, which will affect the subsequent sewing station.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] This invention discloses an automatic bag transfer mechanism with a correction and guide function, including a frame assembly as the main carrier, lifting assemblies installed on both sides of the frame assembly, bag receiving assemblies connected to both sides of the lifting assemblies, a bag clamping assembly installed above the bag receiving assembly, and the two moving synchronously, an electrical limit assembly installed at the rear of the frame assembly, and a bag opening guide assembly connected to a lifting screw located on the frame assembly.

[0006] Furthermore, the bag opening inlet assembly includes an inlet platform, a reduction motor B mounted on top of it, and a set of meshing gears connected to its output end. Below the gears, a folding drive shaft is connected via a universal joint. The folding drive shaft is mounted above the inlet plate via a bearing C. A cylinder is mounted below the inlet platform and connected to a swing arm bracket via a spherical bearing. An inlet plate is mounted below the swing arm bracket. The cylinder controls the opening and closing of the swing arm bracket by extension and retraction. A synchronous pulley is mounted below the folding drive shaft, and the synchronous belt wraps around the synchronous pulley to form a loop. Several sets of guide wheels are mounted below the inlet plate and press the synchronous belt. When the reduction motor B operates, the folding drive shaft drives the synchronous belt to move. Under the action of the guide wheels, the contact surface of the synchronous belt plays a guiding and shaping role.

[0007] Furthermore, the frame assembly is an integral structure in the form of a gantry frame, which is formed by welding square tubes. Chain A is installed on the left and right side columns of the frame, and lifting screws are installed on the upper side of the frame.

[0008] Furthermore, the bag receiving assembly includes guide rails, which serve as the carrier of the assembly. The left and right sides are connected to the mounting frames of the lifting assembly. The bag receiving platform is connected to the sliders of the two sets of guide rails, enabling left and right translation. Bellows covers are installed on the left and right sides of the bag receiving platform, providing dust protection for the guide rails during translation. The mounting frames serve as the transmission carrier for the lifting assembly. Each of the left and right mounting frames has two seated bearings A. The right mounting frame is fitted with a reduction motor A and a drive shaft, which rotate synchronously via two sets of sprockets A and a chain. The left mounting frame is fitted with a driven shaft, with a sprocket A mounted in the middle of each shaft. The open ends of the chain are installed on the left and right sides below the bag receiving platform, forming a closed loop around the sprocket A in the middle of the two shafts. When the reduction motor A starts running, it drives the drive shaft to rotate, and the chain B causes the bag receiving platform to slide left and right on the guide rail assembly.

[0009] Furthermore, the bag clamping assembly includes a bag clamping platform with a slide rail A mounted on top and a slide rail B mounted at the front end in conjunction with an adapter plate. A moving cylinder, guide rods, and guide wheels are sequentially mounted below. When the moving cylinder extends or retracts, the left and right guide rods, in conjunction with the guide wheels, extend or retract synchronously to achieve a balanced and stable effect. An expansion cylinder, in conjunction with two sets of cylinder mounting parts, is mounted above the bag clamping platform. The cylinder head is connected to a Y-joint and, in conjunction with a connecting plate, is connected to the slider of slide rail A. One end of each of the two sets of adjusting rods is connected to the connecting plate, and the other end is connected to the cylinder base plate. The cylinder base plate is mounted above slide rail B. When the expansion cylinder extends or retracts, the connecting plate slides back and forth on slide rail A, and the two sets of adjusting rods drive the cylinder base plate to slide left and right on slide rail B. Two sets of bag clamping cylinders are mounted above the cylinder base plate, and their output ends, in conjunction with a rotating shaft, control the opening and closing of the bag clamping plate. The Y-joint is a connector with an internal thread at one end for connecting the moving end of the cylinder and a Y-shaped circular hole at the other end.

[0010] Furthermore, the lifting assembly includes mounting frames, with two sets of mounting frames installed on the left and right side columns of the frame. A rotating shaft, in conjunction with a bearing B, connects the two sets of mounting frames. Sprockets B are installed on both sides, and the two sets of sprockets B mesh with a chain. A worm gear is mounted on the left end of the rotating shaft. One end of the worm is connected to a rocker arm, and the other end meshes with the worm gear. By rotating the rocker arm and the worm, the rotating shaft is driven to rotate, and the sprockets mesh on the chain A to achieve the lifting function. Both sets of mounting frames are equipped with a front roller, a rear roller, and a locking handle. During lifting, the front roller and the rear roller rotate in contact with the left and right side columns of the frame, playing a balancing and stabilizing role. The worm gear and worm combination has a self-locking function, and the locking handle locks at the matching height, providing a locking and safety function for fixing the lifting assembly.

[0011] Furthermore, the electrical limiting component includes an aluminum profile, which is installed at the rear of the frame. Four sets of optical inspection brackets and optical inspection devices are installed on the aluminum profile for the purpose of detecting and controlling the position of the bag receiving assembly.

[0012] The beneficial effects achieved by this invention are: the mechanism incorporates an automatic feeding function from the feeding port to the subsequent work station. The packaging bag automatically enters the feeding mechanism from the bag clamping point. After being shaped by the rollers between the synchronous belts, the bag opening will enter the subsequent work station in a neat and uniform manner, which can significantly improve the conveying efficiency and safety reliability.

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] Example 1

[0027] like Figure 1-10 As shown, an automatic bag transfer mechanism with a correction and guide function includes a frame assembly as the main carrier, lifting assemblies installed on both sides of the frame assembly, bag receiving assemblies connected to both sides of the lifting assemblies, a bag clamping assembly installed above the bag receiving assembly, and the two moving synchronously, an electrical limit assembly installed behind the frame assembly, and a bag opening guide assembly connected to a lifting screw 3 located on the frame assembly.

[0028] The frame assembly is an integral structure in the form of a gantry frame, which is composed of square tubes welded together to form the frame 1. The chain A2 is installed on the left and right side columns of the frame 1, and the lifting screw 3 is installed on the upper side of the frame 1.

[0029] The bag receiving assembly includes guide rails 5, which serve as the carrier of the assembly. Mounting brackets 29 of the lifting assembly are connected to the left and right sides. The bag receiving platform 4 is connected to the sliders of the two sets of guide rails 5, enabling left and right translation. Bellows covers 6 are installed on the left and right sides of the bag receiving platform 4, providing dust protection for the guide rails 5 during translation. The mounting brackets 29 serve as the transmission carrier for the lifting assembly. Two bearings A12 are mounted on each of the left and right mounting brackets 29. The right mounting bracket 29 is fitted with a reduction motor A8 and a drive shaft 10, and rotates synchronously with the chain via two sets of sprockets A9. The left mounting bracket 29 is fitted with a driven shaft 11, with a sprocket A9 mounted between the two shafts. The open ends of the chain 7 are installed on the left and right sides below the bag receiving platform 4, forming a closed loop around the sprockets A9 between the two shafts. When the reduction motor A8 starts running, it drives the drive shaft 10 to rotate, and the chain B7 causes the bag receiving platform 4 to slide left and right on the guide rail assembly 5.

[0030] The bag clamping assembly includes a bag clamping platform 13, with a slide rail A17 mounted on top, a slide rail B20 mounted at the front end with a connecting plate 26, and a moving cylinder 25, guide rods 27, and guide wheels 28 mounted below. When the moving cylinder 25 extends or retracts, the two guide rods 27 and guide wheels 28 extend or retract synchronously to achieve a balanced and stable effect. An expansion cylinder 14 is mounted above the bag clamping platform 13 with two sets of cylinder mounting parts 15. The cylinder head is connected to a Y-joint 16 and is connected to the slider of the slide rail A17 with a connecting plate 18. One end of two sets of adjusting rods 19 is connected to the connecting plate 18, and the other end is connected to the cylinder base plate 22, which is mounted above the slide rail B20. When the expansion cylinder 14 extends or retracts, the connecting plate 18 slides back and forth on the slide rail A17, and the two sets of adjusting rods 19 drive the cylinder base plate 22 to slide left and right on the slide rail B20. Two sets of bag-clamping cylinders 21 are installed above the cylinder base plate 22. The output end cooperates with the rotating shaft 23 to control the opening and closing of the bag-clamping plate 24. The Y-connector is a connector with an internal thread for connecting the moving end of the cylinder at one end and a Y-shaped round hole at the other end.

[0031] The lifting assembly includes mounting frames 29, with two sets of mounting frames 29 mounted on the left and right side columns of the frame 1. A rotating shaft 33, in conjunction with a seated bearing B34, connects the two sets of mounting frames 29. Sprockets B35 are mounted on both sides, and the two sets of sprockets B35 mesh with the chain 2. A worm gear 32 is mounted on the left end of the rotating shaft 33. One end of a worm 31 is connected to a rocker arm 30, and the other end meshes with the worm gear 32. By rotating the rocker arm 30, the worm 31 drives the rotating shaft 33 to rotate, and the sprockets 35 engage with the chain A2, achieving the lifting function. Both sets of mounting frames 29 are equipped with a front roller 36, a rear roller 37, and a locking handle 38. During lifting, the front roller 36 and rear roller 37 rotate against the left and right side columns of the frame 1, providing balance and stability. The worm gear 32 and worm 31 have a self-locking function; the locking handle 38 locks at a suitable height, providing a locking and safety function for fixing the lifting assembly.

[0032] The electrical limiting component includes an aluminum profile 39, which is installed at the rear of the frame 1. Four sets of optical inspection brackets 40 and optical inspection 41 are all installed on the aluminum profile 39 for the purpose of detecting and controlling the position of the bag receiving component.

[0033] The bag inlet assembly includes an inlet platform 42, on which a geared motor B43 is mounted. A set of meshing gears 44 are connected to the shaft end of the motor. Below the gears 44, two sets of folding drive shafts 46 are connected via two universal joints 45. The folding drive shafts 46 are mounted above the inlet plate 51 via bearings C47. Four sets of cylinders 50 are mounted below the inlet platform 42, connected to two sets of swing arm supports 49 via spherical bearings 48. The inlet plate 51 is mounted below the swing arm supports 49. The cylinders 50 extend and retract, controlling the opening and closing of the swing arm supports 49. Two sets of synchronous pulleys 52 are mounted below the two sets of folding drive shafts 46, and synchronous belts 54 form a loop around the synchronous pulleys 52. Multiple sets of guide wheels 53 are mounted below the inlet plate 51, pressing the two sets of synchronous belts 54 together. When the geared motor B43 starts operating, the folding drive shafts 46 drive the synchronous belts 54 to move. Under the action of the guide wheels 53, the contact surface of the synchronous belts guides and shapes the belts.

[0034] Work process:

[0035] Initial state: The bag clamping platform 13 is at the right origin position, the moving cylinder 25 is retracted, the expanding cylinder 14 is retracted, the bag clamping cylinder 21 is retracted, and the bag clamping plate 24 is in the open state; the cylinder 50 is extended, and the swing arm bracket 49 is in the open state.

[0036] Operating status: The electrical limit component detects the material packaging bag, the moving cylinder 25 extends, and the bag clamping plate 24 reaches the bag mouth clamping position; the bag clamping cylinder 21 extends, and the bag clamping plate 24 closes to clamp the bag mouth; the expansion cylinder 14 extends, and the bag clamping plate 24 slides left and right to tighten the bag mouth; the reduction motor A8 starts running, driving the bag clamping platform 13 to move to the left, and the bag mouth enters the guide plate; the optical detector 41 detects the bag receiving platform position, the bag clamping cylinder retracts, the bag clamping plate 24 opens, and at the same time, the cylinder 50 retracts, the swing arm bracket 49 closes, and the synchronous belt 54 clamps the bag mouth; the moving cylinder 25 retracts, and the bag clamping platform 13 moves backward; the expansion cylinder 14 retracts; the reduction motor A8 rotates in the opposite direction, and at the same time, the reduction motor B43 starts running, the bag clamping platform 13 moves to the right to return to the original position, and the bag clamping plate 24 returns to the initial state to wait for the next packaging bag. When the geared motor B43 starts running, the synchronous belt rotates to shape the bag opening until the bag opening is completely away from the range of the guide plate 51. Then the geared motor B43 stops running, the synchronous belt stops rotating, the cylinder 50 retracts, and the swing arm bracket returns to its initial state, waiting for the next bag opening to be introduced.
