Description

Technical Field

[0001] This invention relates to the field of resource circulation, and more particularly to material distribution and conveying systems. Background Technology

[0002] Material flow within manufacturing plants takes many forms. Taking metal processing plants as an example, some production lines use conveyor belts to transfer materials between machine tools. After one process is completed, the material is transported to the next process via the conveyor belt. However, not all production lines can be linked together by conveyor belts. A heavy-duty stamping machine may be the common starting point for multiple production lines, but multiple different production lines can extend from the stamping machine with little or no connection between them. Machine tools on the same production line are not necessarily close to each other. Material flow and distribution are mainly done by trolleys, while forklifts can be used to transport larger and heavier materials. Outdated material flow methods affect production efficiency.

[0003] Our current solution involves automating material handling by using short-distance conveyor belts and / or robotic arms in conjunction with long-distance conveyor belts between machine tools. For example, after stamping on a heavy-duty stamping machine, the material is transported from a short-distance conveyor belt to a long-distance conveyor belt, which then handles the remaining processes. Alternatively, robotic arms can be used to transport the stamped material to the long-distance conveyor belt, or a combination of methods can be used to ultimately complete the material distribution and flow. The drawbacks of this existing solution are twofold: firstly, conveyor belts occupy too much space and can easily enclose personnel activity areas, restricting personnel movement and significantly impacting worker access. To avoid disrupting factory traffic, conveyor belts cannot truly achieve point-to-point transport. Secondly, while robotic arms are in high demand, their range of motion is limited and their cost is high. Overall, the cost-effectiveness of the existing conveyor equipment is not high, and the efficiency improvement is limited.

[0004] Based on existing industrial automation material handling solutions, we aim to provide a material distribution and conveying solution suitable for the needs of the metal processing and manufacturing industry. This solution needs to address issues related to land occupation, the integrity of the conveying lines, safety and stability, and cost. Summary of the Invention

[0005] To solve the above-mentioned technical problems, a material distribution and conveying system is provided. The provided technical solution includes a pickup unit, a distribution and conveying unit, and a material handling unit.

[0006] The picking unit includes a base, a feeding section, a support section, and a circulating picking section. The top of the base is equipped with an operating table, and the feeding section is located on both sides of the base. The feeding section is used to transport the material processed by the machine tool to the operating table.

[0007] The circulating material picking unit includes at least a strip-shaped support base and a gripper assembly A. There are multiple gripper assemblies A, which are arranged around the outer wall of the support base.

[0008] The support unit includes a support plate, a support rod, a sliding mechanism, a power mechanism, and a self-rotating connector. There are two support plates, which are respectively set on the front and rear sides of the base. The bearing base is slidably mounted on the support rod. The two ends of the support rod are respectively connected to the support plate through the self-rotating connector. The sliding mechanism provides sliding power to the bearing base. The power mechanism drives the self-rotating connector through the transmission mechanism, thereby causing the bearing base to rotate.

[0009] The distribution and conveying unit includes a conveying mechanism and a gripper assembly B. The conveying mechanism is mounted above the picking unit and the material handling unit, and the gripper assembly B is mounted on the conveying mechanism and is driven by it to move along the conveying route.

[0010] The material handling unit includes a lifting mechanism and a support part. The lifting mechanism is used to drive the support part to move up and down, and the support part is used to transport the material located on the gripper assembly B to the lower part.

[0011] Both gripper assembly A and gripper assembly B have structures capable of gripping materials. Gripper assembly A also has a telescopic mechanism that can extend or retract according to the distance of the material. Preferably, there are multiple material handling units.

[0012] Based on the above technical solution, there are multiple conveying mechanisms arranged side by side, and each conveying mechanism is equipped with multiple gripper components B.

[0013] Based on the above technical solution, both gripper assembly A and gripper assembly B have a retractable mechanism.

[0014] Based on the above technical solutions, both gripper assembly A and gripper assembly B have electromagnetic chuck devices.

[0015] Based on the above technical solution, the lifting mechanism is a transmission belt mechanism.

[0016] Based on the above technical solution, the supporting part includes a supporting plate and an electromagnet installed on the supporting plate.

[0017] Based on the above technical solution, the telescopic mechanism adopts an electric push rod.

[0018] Based on the above technical solution, the gripper assembly A further includes a deformable assembly, which includes a fixed sleeve and a swing arm. The fixed sleeve is fitted onto the telescopic mechanism, and one end of the swing arm is hinged to the fixed sleeve, while the other end is fixed to the electromagnetic chuck. Preferably, there are at least two swing arms, and each swing arm is equipped with an electromagnetic chuck.

[0019] Based on the above technical solution, a fixed arm is used to replace the swing arm. One end of the fixed arm is fixedly connected to the fixed sleeve, and the other end is hinged to the electromagnetic chuck.

[0020] Based on the above technical solution, the fixed arm is connected to the electromagnetic chuck through an adjustment component. The adjustment component includes an upper sleeve with internal threads, a lower sleeve, and a fixing component. The fixed arm has external threads. The upper sleeve is threaded to the fixed arm. The lower sleeve is rotated and inserted into the upper sleeve, and the two are restricted from separating by a limiting mechanism. The upper sleeve is fixed to the fixed arm by the fixing component. The electromagnetic chuck is hinged to the bottom of the lower sleeve.

[0021] Beneficial Effects: This system provides a complete material handling system, including a pickup unit for picking up materials from the initial processing stage, a distribution and conveying unit for grabbing and distributing the materials picked up by the pickup unit, and a receiving unit for receiving the materials conveyed by the distribution and conveying unit. This system can supply materials to multiple processing devices, even those on different production lines. The distribution and conveying unit is mounted in the air, occupying a small area, and can be configured according to the actual material flow path of the production line, unaffected by ground-based installations or minimally affected by ground facilities, thus maintaining the integrity of the conveyor line as much as possible. The pickup unit has multiple gripper components A. While gripping materials via a rotating support base, it slides under gripper components B to convey the materials, achieving simultaneous gripping and conveying, improving production efficiency. The system integrates the functions of multiple devices into a single pickup unit.

[0022] As the end of the circulation system, the material handling unit can be deployed in the middle of the path of the conveying mechanism as a node for material transportation, working with the conveyor belt to achieve the final transportation of materials. It can also be used directly as the endpoint of point-to-point transportation, where materials are picked up by the material handling unit and directly enter the subsequent processing steps. It can even be both, configured according to the actual situation of the production line, with flexible configuration and full utilization of existing equipment to reduce costs.

[0023] By setting up multiple conveying mechanisms and multiple gripper components B, different conveying mechanisms can lead to different production lines, which can better realize the material conveying of different production lines, speed up the turnover, and increase the material turnover efficiency.

[0024] Adding a deformation component to gripper assembly A allows for adjustment of the electromagnetic chuck angle when the material shape is complex, enabling it to better adapt to gripping materials of different shapes and providing better material conveying for different production lines.

[0041] Grip assembly A9, support plate 10, support rod 11, sliding mechanism 12, conveying mechanism 13, gripper assembly B14, lifting mechanism 15, support part 16, support plate 17, electromagnet 18, fixed sleeve 19, swing arm 20, fixed arm 21, upper sleeve 22, lower sleeve 23, fixing part 24. Implementation Example

[0042] This embodiment provides a conveying system that can provide material distribution and conveying services for multiple production lines. The specific usage principle is as follows:

[0043] 1. The stamping machine starts stamping, and the stamped material is fed into the feeding section 5 of the picking unit 1;

[0044] 2. The material slides along the feed section 5 toward the base 4. When the material slides into the operating table 7 on the base 4, the conveying operation is ready to start.

[0045] 3. Activate the sliding mechanism 12 of the support section, which drives the bearing base 8 of the circulating material picking section 6 to slide along the support rod 11;

[0046] 4. When a gripper assembly A9 on the support base 8 moves to a suitable position above the material, the support base 8 stops sliding;

[0047] 5. Start the power mechanism to drive the self-rotating connector to rotate. The self-rotating connector drives the support rod 11, sliding mechanism 12, bearing base 8 and other structures to rotate together, so that the gripper assembly A9 is facing the material.

[0048] 6. Activate the retractable mechanism of gripper assembly A9 to bring gripper assembly A9 into contact with the material and grip it;

[0049] 7. Restart the power mechanism to drive the bearing base 8 to rotate, so that the gripper assembly A9 for grabbing materials is vertically upward;

[0050] 8. Start the conveying mechanism 13 of the distribution and conveying unit 2, which will drive the gripper assembly B14 to move above the material;

[0051] 9. Reactivate the retractable mechanism of gripper assembly A9 to allow gripper assembly B14 to contact the material;

[0052] 10. When gripper assembly B14 comes into contact with the material, gripper assembly A9 releases the material and gripper assembly B14 grips the material;

[0053] 11. Restart the conveyor mechanism 13 to move the material toward the next process;

[0054] 12. When the material moves above the material handling unit 3, the lifting mechanism 15 drives the supporting part 16 to move upward, supporting the material on the gripper assembly B14. At the same time, the gripper assembly B14 releases the material and restarts the lifting mechanism 15 to drive the material down. At this time, the material arrives at the next process.

[0055] The gripper assemblies A9 are arranged in an array on the support base 8 and are arranged around the outer wall of the support base 8. Since the stamped parts are large, sufficient spacing needs to be maintained between adjacent gripper assemblies A9 to avoid collisions.

[0056] In this embodiment, gripper assembly A9 and gripper assembly B14 are used to grip materials. Since the stamping machine produces metal stamping parts, the structure of gripper assembly A9 and gripper assembly B14 can adopt conventional mechanical gripper solutions for gripping metal products, such as vacuum chucks, but electromagnetic chucks are preferred as the gripping solution. The telescopic mechanism can also adopt mature solutions, such as cylinders, and an electric push rod is preferred as the telescopic structure solution. When the material is conveyed to the operating table 7, the telescopic mechanism of gripper assembly A9 extends, driving the electromagnetic chuck to adsorb the material. The feeding part 5 can use gravity for material conveying, such as... Figures 1 to 3 As shown, there is a height difference between the feeding section 5 and the stamping part, and the material can be slid onto the operating table 7 by gravity.

[0057] In this embodiment, the conveying mechanism 13 can adopt a mature solution, such as a crane, but it is preferred to use an existing overhead chain mechanism. Since the weight of the stamped part is within an acceptable range, the gripper assembly B14 is mounted on the hook of the overhead chain mechanism or other structure used for mounting, which can achieve stable conveying.

[0058] Material picking unit 3 can serve as the endpoint of the material conveying path in the entire system, or multiple material picking units 3 can be used, making it both the endpoint and a node in the material conveying path. Based on this conveying system, the layout of machine tools within the factory can be arranged according to processes. For example, shearing, CNC punching, CNC bending, leveling, and laser cutting equipment can be grouped together by type. Stamping machines can also be grouped together, with picking unit 1 positioned on one side of the stamping machine. All materials from the stamping machines are then conveyed from picking unit 1 to the next process. The equipment for the second process can also be grouped together, with a material picking unit 3 positioned at the second process location as a distribution node. All machine tools in this process can be arranged around this node, forming a "relatively isolated island" layout, rather than a traditional linear layout. The conveyor belt travel time serving this node can be shortened, and due to the centralized equipment layout, the conveyor belt can also connect all equipment uninterruptedly without worrying about land occupation or affecting worker access; only a unified entrance and exit is required. Other processes are arranged similarly, which can greatly improve the utilization rate of the factory space, allowing for the placement of more equipment and paving the way for increased production. The sliding mechanism 12 and the power mechanism (not shown) can adopt conventional solutions. The sliding mechanism 12 preferably uses an electric slide rail, with both ends of the rail fixed to the self-rotating connector, just like the support rod 11. The slider of the rail is connected to the bearing base 8. The bearing base 8 can be hollow to accommodate the sliding mechanism 12, allowing the electric slide rail and support rod 11 to pass through it. The slider is fixedly connected to the inside of the bearing base 8 via the frame. The purpose of the self-rotating connector is to support the support rod 11, the sliding mechanism 12, and other related structures and drive their rotation. The power mechanism can preferably be a motor.

[0059] Multiple gripper assemblies B14 can be arranged on a conveying mechanism 13. The number of gripper assemblies B14 can also correspond to the number of gripper assemblies A9. The gripper assemblies B14 can adopt the same or similar structure as A9. Any gripping scheme can be used, or an electromagnetic chuck scheme can be adopted.

[0060] like Figure 1 , Figure 4 and Figure 8 As shown, the support plate 10 of the support part of the picking unit 1 stands on the ground on the front and rear sides of the base 4, which facilitates the feeding of materials from the left and right sides of the base 4. However, if it is necessary to feed materials from a third or even more directions, the structure of the support plate 10 can be adapted. It can be any shape, as long as it provides connection and support for the support rod 11, sliding mechanism 12 and other structures. It does not necessarily have to be plate-shaped.

[0061] The supporting part 16 is actively raised by the lifting mechanism 15. When the supporting part 16 reaches its highest point of travel, it comes into contact with the material gripped by the gripper assembly B14. The lifting mechanism 15 can be any design, but to improve material conveying efficiency, a conveyor belt mechanism is preferred. The conveyor belt mechanism is vertically arranged through the frame, and the supporting part 16 is connected to the conveyor belt. The supporting part 16 can reciprocate, and when multiple supporting parts 16 are provided, uninterrupted material conveying can be achieved. The shape and structure of the supporting part 16 are not limited, as long as it can support the material. Due to the large size of the material, the supporting part 16 can be composed of a supporting plate 17 and an electromagnet 18. The electromagnet 18 on the supporting part 16 can also prevent the extreme situation of material slipping off the supporting part 16. Figure 10 and Figure 11 As shown, when conveying materials that are large in size and weight, a single lifting mechanism 15 and supporting part 16 may not be effective. Therefore, two lifting mechanisms 15 can be set up, and the supporting part 16 on each lifting mechanism 15 moves synchronously to support the material from both sides, thereby increasing the stability of material handling. Example

[0062] This embodiment is based on the first embodiment. By optimizing the picking unit 1 and the distribution and conveying unit 2, a scheme with higher conveying and distribution efficiency is proposed.

[0063] In order to better carry out transportation and distribution, such as Figures 5-7 As shown, the front view, left view, and right view of the support base 8 and the gripper assembly A9 are presented respectively. The number of gripper assemblies A9 shown in the figures is used as an example for illustration; however, it should be noted that the number of gripper assemblies A9 shown in the figures is for illustrative purposes only and is not intended to limit the actual number. Figures 5 to 7 For example, there are 25 gripper components A9. For ease of description, the first 20 gripper components A9 are described and numbered, grouped into groups of ten. The first group is numbered from 1 to 10, and the second group is numbered from 11 to 20. Figure 6 As shown, in order to avoid collisions between the gripped materials, the gripper assembly A9 can be arranged in a staggered manner in this embodiment.

[0064] like Figure 4 and Figure 9 As shown, in this embodiment, there can be multiple conveying mechanisms 13, which are numbered using letters. Multiple gripper assemblies B14 can be installed on each conveying mechanism 13.

[0065] The specific operating principle and method of this embodiment are as follows:

[0066] 1. When the materials to be transported are the same;

[0067] 1. Activate the sliding mechanism 12 to drive the bearing base 8 to slide;

[0068] 2. Start the power mechanism to drive the bearing base 8 to rotate. When the No. 1 gripper assembly A9 (hereinafter referred to as No. 1, and so on) is facing the operating table 7, the sliding mechanism 12 and the power mechanism stop.

[0069] 3. When the material slides into the operating table 7, activate the No. 1 telescopic mechanism to drive the electromagnetic chuck to adsorb the material;

[0070] 4. When the material continues to slide into the operating table 7, the sliding mechanism 12 and the power mechanism are activated at the same time, so that No. 3 is facing the operating table 7, and the No. 3 telescopic mechanism is activated to drive the electromagnetic chuck to adsorb the material.

[0071] 5. After No. 5, No. 7 and No. 9 have respectively adsorbed and grabbed the material, the sliding mechanism 12 and the power mechanism are activated to drive No. 9, which grabbed the last material, to rotate to face directly upward and slide to the bottom of the nearest gripper assembly B14. The telescopic mechanism is activated to transfer the material to the gripper assembly B14.

[0072] 6. At this time, No. 4 is facing the operating table 7. Start No. 4 to telescopically grab the material, rotate the supporting base, and make No. 6, No. 8, No. 10 and No. 2 grab the material in sequence. Drive No. 2, which grabs the last material, to rotate to face directly upward and slide to the bottom of the nearest gripper assembly B14. Start the telescopic mechanism to transfer the material to gripper assembly B14.

[0073] 7. Repeat steps 5 and 6 until the gripper assembly A9 has completed one material conveying cycle, then repeat step 1 on the support base 8.

[0074] 2. However, when the materials to be transported are different, the steps for when the materials are the same can be referred to. The difference is that the stamping machines on both sides of the picking unit 1 produce different products. Therefore, after picking unit 1 picks up the first type of product, the second type of product slides into the operating table 7. In order to avoid material accumulation, picking unit 2 should pick up the other type of product, picking unit 3 should pick up the first type of product, picking unit 4 should pick up the second type of product, and so on. When it is necessary to transport materials to the distribution and conveying unit 2, different conveying mechanisms 13 can be selected according to the destination. For example, the product picked up by picking unit 1 needs to be transported through the nearest first conveying mechanism 13, while picking unit 2 needs to be transported through the second conveying mechanism 13. In this way, fast picking and fast distribution can be achieved, and the goal of products not falling to the ground during the production process can be achieved. The products can be quickly delivered to the processing point for processing, and the production efficiency can be improved. Example

[0075] This embodiment provides a gripper assembly A9 capable of adapting to gripping materials of different shapes. The specific structure of the gripper assembly A9 is provided, such as... Figure 12 and Figure 13As shown, a fixed sleeve 19 is provided at the end of the telescopic mechanism. A swing arm 20 is hinged to each side of the fixed sleeve 19. An electromagnetic chuck is installed on each swing arm 20. The swing arms 20 can be locked together by any means. When it is necessary to grasp materials with a complex surface structure, the limiting measures between the swing arms 20 are released and the angle of the electromagnetic chuck is adjusted to facilitate adsorption. Example

[0076] This embodiment provides another gripper assembly A9 capable of adapting to gripping materials of different shapes. For example... Figure 13 As shown, the electromagnetic chuck may have the problem of excessive swing amplitude. In this embodiment, the swing arm 20 is removed and a fixed arm 21 is used instead of the swing arm 20. One end of the fixed arm 21 is fixedly connected to the sleeve, and the other end is hinged to the electromagnetic chuck through a hinge, so that the electromagnetic chuck can rotate and swing with a small radius, which can better adapt to the shape of the material. Example

[0077] This embodiment is an improvement on the fourth embodiment, forming a variant of the fourth embodiment, and provides a gripper assembly A9 that can extend and retract slightly up and down. The extension and retraction effect of the gripper assembly A9 is achieved by adjusting the assembly.

[0078] The upper sleeve 22 and lower sleeve 23 of the adjusting assembly are pre-assembled together. The lower sleeve 23 can rotate freely within the upper sleeve 22, but the two are prevented from separating or are restricted from separating by a limiting component. The upper sleeve 22 is threaded onto the fixed arm 21 and then fixed by a fixing component 24. The fixing component 24 can be a locking component, etc., and preferably a fixing bolt is used to pass through the upper sleeve 22 for fixing.

[0079] The electromagnetic chuck is still hinged to the bottom of the lower sleeve 23. When the material to be gripped has a complex structure, the angle can be adjusted by rotating the electromagnetic chuck. The upper sleeve 22 can also be slid on the fixed arm 21 for telescopic adjustment, so as to adjust the two electromagnetic chucks to different heights and angles for better gripping of materials.
