Description

Technical Field

[0001] This invention relates to the field of bag sorting machine technology, and more particularly to an integrated bag sorting machine. Background Technology

[0002] Materials individually packaged in bags usually need to be placed in boxes or larger bags for easier transport and storage. However, for long, narrow bags, due to their unusual shape, directly conveying materials with haphazard orientations and disordered arrangement via conveyor belts may cause conveyor jams and packing blockages. Additionally, some manufacturers have specific requirements regarding the orientation of the bagged materials and the direction they face upwards.

[0003] Therefore, corresponding equipment is needed to meet various bag sorting requirements. For example, regarding the orientation of bagged materials, i.e., horizontal or vertical placement, Chinese utility model patent No. ZL202222753809.4 discloses an automatic bag sorting machine, including a sorting section and a conveying section. Several photoelectric eyes are evenly arranged above the sorting section to monitor the material on the surface of the rollers below. Multiple rows of spacing adjustment rollers, multiple rows of rejection rollers, directional rejection rollers, and single rows of spacing adjustment rollers are arranged in a row on the sorting section. The multiple rows of rejection rollers reject the outer material, and the directional rejection rollers work in conjunction with the sweeping rollers to reject horizontally placed materials.

[0004] For other bag-sorting requirements, such as the direction of the bag's ends or its orientation upwards, additional bag-sorting equipment is needed. Ultimately, the bagged materials must pass through these bag-sorting devices sequentially to meet all bag-sorting requirements. Therefore, a complete bag-sorting system often requires significant cost and floor space. Summary of the Invention

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0042] like Figure 1As shown, this embodiment provides an integrated bag sorting machine, including a frame 1, a differential speed separation mechanism 2, a direction adjustment mechanism 3, a transfer channel 4, a first conveyor line 5, a co-directional mechanism 6, a channel selection mechanism 7, a co-face mechanism 8, and a second conveyor line 9, all mounted on the frame. The differential speed separation mechanism 2 houses the direction adjustment mechanism 3. The first conveyor line 5 is located below the differential speed separation mechanism 2. The transfer channel 4 connects the discharge end of the differential speed separation mechanism 2 to the feed end of the first conveyor line 5. The co-directional mechanism 6 is located on the first conveyor line 5. The second conveyor line 9 is located below the first conveyor line 5. The co-face mechanism 8 is located between the first conveyor line 5 and the second conveyor line 9. The channel selection mechanism 7 is located between the first conveyor line 5 and the co-face mechanism 8. The first conveyor line 5 and the second conveyor line 9 can be conventional belt conveyors. The overall working principle of this embodiment is as follows: The differential separation mechanism 2 is itself a conveyor line. Therefore, the differential separation mechanism 2, the first conveyor line 5, and the second conveyor line 9 are distributed vertically, meaning the entire equipment has three vertically distributed conveyor lines. First, the bagged material passes through the differential separation mechanism 2, achieving separation between materials during conveying, thus forming a state of sequential, intermittent conveying. Generally, the direction adjustment mechanism 3 is located downstream of the differential separation mechanism 2. After the materials are basically separated, they pass through the direction adjustment mechanism 3 to align their directions. This direction applies to long or rectangular materials, which are placed horizontally or vertically on the conveyor line, or in other words, the width direction of the material is the same as the conveying direction (horizontal) or the length direction is the same as the conveying direction (vertical). Then, materials arranged sequentially and in the same direction pass through transfer channel 4 and enter the first conveyor line 5. On the first conveyor line 5, they first pass through the same-direction mechanism 6. An image recognition device is generally installed upstream of the same-direction mechanism 6 to identify materials with incorrect head and tail orientation, thereby accurately reversing the orientation of the incorrectly oriented materials and conveying materials with the correct head and tail orientation to the rear. To improve efficiency, this embodiment sets up two sets of same-direction mechanisms 6, each with an image recognition device upstream. Of course, more sets of same-direction mechanisms can be set up depending on equipment specifications. Next, the materials continue to be conveyed along the first conveyor line 5 and reach the upstream of the channel selection mechanism 7. Again, the materials are identified by the image recognition device. If the orientation is correctly identified as upward, the channel selection mechanism 7 remains unchanged, and the materials continue to be conveyed along the first conveyor line 5 until discharge. If the orientation is incorrect, the channel selection mechanism 7 activates, conveying the materials downward to the same-face mechanism 8. After being flipped by the same-face mechanism 8, the materials change their orientation and fall to the second conveyor line 9, where they are conveyed until discharge.

[0043] The structure and working principle of each mechanism are described below.

[0044] like Figure 2 As shown, the differential separation mechanism 2 includes multiple sets of sequentially connected bag-feeding roller assemblies 231 and a material sensor 232 located at the tail end of each set of bag-feeding roller assemblies 231. A speed controller is provided between the bag-feeding roller assemblies 231 and the material sensors 232. The structure of the bag-feeding roller assembly 231 is relatively conventional, with six rollers connected by pulleys and belts and driven by a servo motor. The material sensor 232 is generally a photoelectric sensor. The working principle of the differential separation mechanism is as follows: when material A passes the material sensor at the tail end of the first set of bag-feeding roller assemblies, that is, when material A enters the second set of bag-feeding roller assemblies, the first set of bag-feeding roller assemblies decelerates, while the speed of the second set of bag-feeding roller assemblies containing material A remains unchanged, thus increasing the distance between material A and subsequent materials. This process continues, and after the differential separation action of more than ten sets of bag-feeding roller assemblies, all materials can be effectively separated.

[0045] like Figure 3 As shown, the differential separation mechanism 2 is inclined along its width, with a baffle 223 on the lower side, allowing materials to move towards the baffle 223 under gravity, thus ensuring all materials are conveyed along the same straight line. Meanwhile, as... Figure 1 As shown, the differential separation mechanism is inclined along its length, with the discharge end higher than the feed end. This allows materials stacked on top of other materials to naturally slide off under gravity and vibration during the conveying process. Furthermore, after a portion of the material slides down, as it passes two adjacent sets of bag-sorting roller assemblies, the lower material contacts the upstream set, while the upper portion sliding down contacts the downstream set. The differential speed operation of the two sets of bag-sorting roller assemblies facilitates the separation of the stacked materials. Of course, a direction adjustment mechanism is also included within the differential separation mechanism and has a corresponding structure.

[0046] like Figure 4 As shown, the discharge end of the differential separation mechanism 2 is equipped with a discharge roller assembly 25, which is set close to the baffle 223. A screening channel 261 is provided on the side of the discharge roller assembly 25, and an identification device and a blow-off device 262 are provided above the screening channel 261. The width of the discharge roller assembly 25 is approximately the same as the width of the bagged material. Therefore, when the bagged material passes normally along its length direction, it can pass through the discharge roller assembly 25 and enter the transfer channel 4. However, when the bagged material is tilted or horizontal, part of it will extend above the screening channel 261 as it passes through the discharge roller assembly 25, and be identified by the identification device, triggering the blow-off device 262 to blow the bagged material into the screening channel 261 for direct output. The identification device can generally be an image recognition device, and the blow-off device 262 can be provided with high-pressure gas by a high-pressure pump.

[0047] like Figure 5 As shown, the direction adjustment mechanism 3 includes an adjustment roller conveyor 31 and a steering device 32. The width of the adjustment roller conveyor 31 is along its first side ( Figure 5 The width gradually decreases from the lower middle side. The first side of the adjusting roller conveyor 31 is equipped with the steering device 32, and the second side of the adjusting roller conveyor 31 is the baffle 223. The steering device 32 has a conveying surface facing one side of the adjusting roller conveyor 31. This conveying surface is adapted to the shape of the first side of the adjusting roller conveyor 31, i.e., it is inclined. The conveying speed of this conveying surface is different from that of the adjusting roller conveyor 31. Working principle: The conveying direction of the adjusting roller conveyor 31 is from the wider end (…). Figure 5 (middle left end) towards the narrower end ( Figure 5 The narrower end of the adjusting roller 31 is matched to the width of the bagged material. Thus, on the one hand, the bagged material can only pass through the narrower end of the adjusting roller 31 along its length, and the width variation structure of the entire adjusting roller 31 itself has a guiding function; on the other hand, to prevent bagged material with irregular orientation from getting stuck at the narrower end of the adjusting roller 31, the steering device 32 applies a conveying force different from the conveying speed of the adjusting roller 31 to the skewed bagged material, thereby causing the skewed bagged material to rotate, ultimately allowing the bagged material to pass through the narrower end of the adjusting roller 31 along its length, ensuring the consistency of the output direction of the bagged material, that is, along the length direction of the material. It should be noted that the conveying speed of a roller 32 generally has certain requirements and cannot be arbitrarily adjusted. If the conveying speed of the steering device 32 is made less than that of the adjusting roller 31, even if the conveying speed of the steering device 32 is reduced to zero, the required speed difference may not be achieved. Of course, the conveying direction of the steering device 32 can also be made opposite to that of the adjusting roller 31, which can achieve the purpose of steering, but will affect the conveying efficiency. Therefore, in this embodiment, the conveying direction of the turning device 32 is the same as that of the adjusting roller 31, and the conveying speed of the turning device 32 is greater than that of the adjusting roller 31. The conveying speed of the turning device can be adjusted according to the actual situation to achieve a better turning effect of the bagged material without affecting the conveying efficiency of the bagged material.

[0048] Specifically, the adjusting roller conveyor 31 is connected to a transition roller conveyor 34 with the same width at its narrower end. The width of the transition roller conveyor 34 is adapted to the width of the bagged material, making the direction of the bagged material more stable and accurate after passing through the transition track. Correspondingly, the steering device 32 also has a portion located on one side of the transition roller conveyor 34. The steering device 32 and the baffle 223 also constitute the two side walls of the guide structure of the transition roller conveyor 34.

[0049] like Figure 6As shown, the steering device 32 includes a steering motor 321, a driving pulley 322, four driven pulleys 323, a belt 324, a first base 325, and a housing. The belt 324 has the conveying surface. The driving pulley 322 and the four driven pulleys 323 are mounted on the first base 325. The steering motor 321 is located below the first base 325, and its output end is connected to the driving pulley 322 via a synchronous pulley and a synchronous belt. The belt 324 covers the outer sides of the driving pulley 322 and the four driven pulleys 323. Except for the sides facing the adjusting roller conveyor 31 and the transition roller conveyor 34, the other sides and the top surface are provided with a housing. To make the transmission between the driving pulley 322 and the belt 324 more stable, the driving pulley 322 is located at the narrower end of the entire steering device, thus increasing the contact area between it and the belt and making the transmission more stable and reliable.

[0050] To prevent bagged materials from being squeezed between the baffle 223 and the steering device 32 and causing unexpected situations such as bouncing, the steering device 32 is provided with a limiting plate 35 on the side facing the adjusting roller 31 and on the baffle 223.

[0051] like Figure 7-9 As shown, the co-directional mechanism 6 includes a second base 61, a lifting assembly, a rotating assembly, and a straw 62. The lifting assembly and the rotating assembly are mounted on the second base 61. The straw 62 is vertically and horizontally connected to the second base 61. The output end of the lifting assembly is axially and rotatably connected to the straw 62, and the output end of the rotating assembly is circumferentially and slidably connected to the straw 62. The working principle of this mechanism is as follows: when the bagged material reaches below the mechanism and the material orientation needs to be adjusted, the lifting assembly moves, causing the straw 62 to approach the material surface downwards. The straw uses a vacuum pump or other equipment to generate suction to hold the material. Then, the rotating assembly drives the straw to rotate 180 degrees, thereby changing the orientation of the material. Finally, the straw releases the material, and the lifting assembly drives the straw to return to its original position. To improve adsorption stability and avoid damage to the material packaging caused by the straw, the lower end of the straw 62 is provided with an elastic nozzle 65. The elastic nozzle adapts more easily to the shape of the material surface, ensuring the adsorption effect, while the elastic material is less likely to damage the material packaging.

[0052] Specifically, the lifting assembly includes a support 631, a lifting motor 632, a screw 633, a nut 634, and a lifting plate 635. The screw 633 is axially and rotatably connected to the support 631. The nut 634 is mounted on the lifting plate 635, and the screw 633 is threadedly connected to the nut 634. The lifting motor 632 is drively connected to the screw 633, and the lifting plate 635 is axially and rotatably connected to the straw 62. Thus, the lifting motor 632 drives the screw 633 to rotate, and the screw 633, through its threaded engagement with the nut 634, drives the lifting plate 635 to rise and fall, while the straw 62 rises and falls synchronously with the lifting plate 635. The specific connection method between the lifting plate 635 and the straw 62 can be as follows: the lifting plate 635 is provided with a first bearing 636, and the straw 62 is provided with first limiting clamps 6361 on both the upper and lower sides of the first bearing 636. The first limiting clamps 6361 can be installed and positioned by opening an annular groove on the straw 62, so that the straw 62 cannot slide up and down relative to the lifting plate 635, while not affecting the rotation of the straw 62. Similarly, the connection method between the screw 633 and the support 631 is similar, that is, the support 631 is provided with a second bearing 637, and the screw 633 is provided with second limiting clamps on both the upper and lower sides of the second bearing 637.

[0053] To maximize the lifting range without increasing the overall height of the mechanism, the support 631 includes a support plate 6311 and multiple support legs 6312. The lifting motor 632 is located above the support plate 6311, and its output end is connected to the screw 633 below the support plate 6311. This design places the connection between the lifting motor and the screw at the lower end, providing sufficient space for the lifting of the upper lifting plate.

[0054] The rotating assembly includes a rotary motor 641, a driving synchronous pulley 642, a driven synchronous pulley 643, and a synchronous belt. The driving synchronous pulley 642 is located at the output end of the rotary motor 641. The driven synchronous pulley 643 is circumferentially slidably connected to the suction tube 62 and axially rotatably connected to the second base 61. While the transmission method using a motor, synchronous pulleys, and a synchronous belt is conventional, the rotary motor 641 needs to be fixedly mounted on the second base 61, and the suction tube 62 needs to be raised and lowered. Therefore, the driven synchronous pulley 643 on the suction tube 62 needs to slide relative to the suction tube 62 while rotating synchronously. To address this, the second base 61 is provided with a third bearing 644. The driven synchronous pulley 643 has third limiting clamps 6441 on both the upper and lower sides of the third bearing 644, preventing it from moving up and down without affecting its rotation, thus ensuring stable engagement with the driving synchronous pulley at the output end of the rotary motor. Meanwhile, the straw 62 is provided with a sliding limiting groove 621 along its axial direction on its side, and a circumferential limiting block is provided between the driven synchronous pulley 643 and the sliding limiting groove 621, so that the straw 62 can slide up and down along the driven synchronous pulley 643, and the two can rotate synchronously.

[0055] In addition, the output end of the rotary motor 641 is located below the second base 61 to leave space for other components on the base and avoid interference between them.

[0056] like Figure 10As shown, the channel selection mechanism includes a connecting conveyor platform 71, a support base 72, a swing arm 73, a connecting rod 74, and a drive device 75. Two connecting conveyor platforms 71 are arranged adjacently in the first conveyor line 5, and the opposite ends of the two connecting conveyor platforms 71 are rotatably connected to the first conveyor line 5. The middle part of the swing arm 73 is rotatably connected to the support base 72, and the two ends of the swing arm 73 are rotatably connected to the adjacent parts of the two connecting conveyor platforms 71 through the connecting rod 74. The drive device 75 is drivenly connected to the swing arm 73. Since the middle part of the swing arm 73 is rotatably connected to the support base 72, when the swing arm 73 rotates, its two ends will rise and fall respectively, thereby driving the two connecting conveyor platforms 71 to rotate upward and downward respectively. The downward rotating connecting conveyor platform connects with the same-plane mechanism 8, thereby realizing the conveying of materials on the first conveyor line 5 to the same-plane mechanism 8. The synchronously upward rotating connecting conveyor platform frees up enough space for the materials. When the connecting conveyor platform 71 rotates at a small angle, it can convey materials to the same-plane mechanism 8, improving the overall working efficiency. The working principle of this mechanism is as follows: When the material facing upward is correctly conveyed normally along the first conveyor line 5, the two connecting conveyor platforms 71, as part of the entire first conveyor line 5, are responsible for the horizontal conveying of materials. When the upstream image recognition system detects incorrectly facing material, the two connecting conveyor platforms 71 rotate synchronously, and the material enters the same-plane mechanism 8 along the downward rotating connecting conveyor platform. Then the two connecting conveyor platforms reset and continue the material conveying work.

[0057] like Figure 11 As shown, the swing arm 73 is rotatably connected to the support base 72 via a rotating shaft 731. The driving device 75 is a cylinder, and a driving arm 77 is provided between the output end of the cylinder and the rotating shaft 731. Since the two connecting conveying platforms rotate synchronously up and down, the rotation amplitude does not need to be too large to form a channel for material conveying downward. Correspondingly, the rotation amplitude of the swing arm 73 is small, and a cylinder can meet the requirements. At the same time, the cylinder's operation is more efficient. To adapt to the positional changes of the driving arm 77 during rotation, the cylinder is mounted on a cylinder base 78. The main body of the cylinder is rotatably connected to the cylinder base 78, and the output end of the cylinder is rotatably connected to the driving arm 77.

[0058] To ensure the stability of the swing arm's movement, an expansion sleeve 732 is provided between the swing arm 73 and the rotating shaft 731 to prevent slippage between the swing arm and the rotating shaft. To ensure the stability of the transmission between the swing arm and the connecting conveyor platform, each end of the swing arm 73 is provided with a connecting shaft 733, and each end of the connecting shaft 733 is rotatably connected to a connecting rod 74. The two connecting rods 74 at each end of the connecting shaft 733 are respectively rotatably connected to both sides of the connecting conveyor platform 71, meaning each connecting conveyor platform 71 is pulled and supported by two connecting rods 74. Furthermore, the vertical width of the swing arm 73 gradually decreases from the middle to both ends and along both sides; that is, the middle of the swing arm is wider to improve structural strength, while the width gradually decreases at both ends to avoid collision with the bottom surface of the support base 72 during rotation.

[0059] like Figure 12 As shown, to save costs, the connecting conveyor platform 71 is synchronously connected to the first conveyor line 5, so that the power of the first conveyor line 5 drives the connecting conveyor platform 71, thereby saving the drive device and related transmission components. Specifically, the connecting conveyor platform 71 includes a connecting conveyor roller 711 and a connecting conveyor belt 712, and the first conveyor line 5 includes a first conveyor roller 51 and a first conveyor belt 52. The connecting conveyor platform 71 is rotatably connected to its adjacent first conveyor roller 51, and the adjacent connecting conveyor roller 711 and the first conveyor roller 51 are connected by a synchronous pulley 781 and a synchronous belt 782. When the connecting conveyor platform rotates, the distance between the connecting conveyor roller 711 and the first conveyor roller 51 remains unchanged, and a stable transmission relationship can be maintained between them. The upper conveyor line is a belt conveyor, the detailed structure of which will not be described in detail.

[0060] like Figure 13-16As shown, the same-face mechanism 8 includes a spiral plate 81 and a cover 82 disposed above the spiral plate 81. A bag-feeding channel is formed between the spiral plate 81 and the cover 82. The spiral plate 81 is inclined, with the higher end being the feed end and the lower end being the discharge end. The spiral plate 81 has 0.25-0.5 spiral turns. Specifically, in this embodiment, the spiral plate has approximately 0.375 spiral turns, or the relative twist angle between the two ends of the spiral plate is approximately 135°. This ensures that the bagged material can be effectively turned over after passing through the spiral plate, while avoiding adding ineffective spiral parts, or, given a fixed spiral plate length, avoiding excessive twist angle that could cause material jamming. The inclination angle of the spiral plate 81 is 30°-45° to allow the material to slide smoothly and to fit as close to the spiral plate as possible, ensuring a good turning effect. The principle of this mechanism is as follows: the bagged material enters from the higher end of the spiral plate, slides down the spiral plate under its own gravity, and is flipped over by the spiral structure. Then, it loses support and falls downwards onto the second conveyor line 9, completing the flipping of the bagged material. Of course, an image recognition device is usually installed upstream of this mechanism to identify incorrectly facing material and transport the corresponding material back to this mechanism.

[0061] Specifically, the two ends of the spiral plate 81 are connected to the cover 82 by screws for easy disassembly and maintenance. Due to manufacturing considerations, the spiral plate 81 is generally made of a thin sheet material, thus lacking sufficient thickness for screw connection. Therefore, a bent portion 811 is formed by bending both ends of the spiral plate 81, and a mounting shaft 83 is inserted into the bent portion. Screw holes at both ends of the mounting shaft 83 are used to connect the screws, achieving stable installation.

[0062] The mounting shaft at the feed end of the spiral plate is generally horizontal to facilitate material reception. However, since the torsion angle of the spiral plate 81 does not need to be too large, the mounting shaft at the discharge end is often inclined. Meanwhile, the structure of the cover 82 includes two vertical plates 821 on both sides and an arc-shaped plate 822 connecting the upper ends of the two vertical plates 821. The two ends of the inclined mounting shaft at the discharge end need to be connected to one side of the vertical plate 821 and the arc-shaped plate 822 respectively. One end of the mounting shaft can just vertically abut against the arc-shaped plate, while the other end has a certain angle and gap with the vertical plate 821, making a stable connection impossible. Therefore, a shim 84 is placed between this end of the mounting shaft 83 and the vertical plate 821 to fill the gap and ensure connection stability. The shim 84 has connecting surfaces that respectively fit the mounting shaft 83 and the cover 82, and a connecting hole runs through the two connecting surfaces. Screws are then passed through the vertical plate 821 and the shim 84 to connect with the mounting shaft 83, ensuring connection strength. The vertical plate 821 is provided with multiple mechanism mounting holes 8211 to facilitate installation in equipment such as bag sorting machines.

[0063] To prevent materials sliding off the spiral plate from interfering with each other and affecting the flipping effect, a second conveyor line 9 is located below the discharge end of the spiral plate 81 to promptly transport materials below the spiral plate 81, ensuring the flipping effect of subsequent materials. Furthermore, to improve the mating surface between the cover 82 and the second conveyor line 9 and prevent materials from falling out through the gap between the second conveyor line 9 and the cover 82, the lower end of the vertical plate 821 of the cover 82 has a chamfer 8212 that mates with the second conveyor line 9.

[0064] like Figure 17 As shown, the upstream end of the differential separation mechanism 2 is provided with a feeding mechanism 10. The feeding mechanism 10 includes a feeding belt conveyor 101 and a feeding roller conveyor 102. The feeding roller conveyor 102 is connected to the feeding end of the differential separation mechanism 2. The discharge end of the feeding belt conveyor 101 is located above the feeding roller conveyor 102. The conveying direction of the feeding belt conveyor 101 is perpendicular to the feeding roller conveyor 102, thereby shortening the length of the entire equipment and further reducing the floor space.

[0065] The above description is merely a preferred embodiment of the present invention, and is one implementation method based on the overall concept of the present invention. Furthermore, the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
