Description

Technical Field

[0001] This invention relates to the field of metal sheet receiving technology, specifically a receiving and unloading device applicable to all sizes and shapes. Background Technology

[0002] Material handling equipment is mainly used in the material conveying process of industrial production to automate the receiving and placement of materials, replacing manual operation and improving production efficiency. However, existing material handling devices have many limitations in practical applications:

[0003] For materials of different sizes, it is often necessary to change specific fixtures or adjust complex mechanical structures, which has poor adaptability and makes it difficult to meet the needs of flexible production.

[0004] For materials of various shapes, especially curved, irregular, or irregularly protruding materials, traditional rigid gripping methods can easily cause damage to the material surface or unstable gripping, leading to the material falling off.

[0005] Some devices are only applicable to materials of a single type. Different equipment is required for ferromagnetic and non-ferromagnetic materials, which increases the equipment investment cost and floor space. Furthermore, the positioning accuracy is insufficient during the connection between material conveying and gripping, often resulting in material deviation and inaccurate gripping position, which affects the smooth progress of subsequent processes. In addition, some lightweight and easily floating materials are prone to posture disorder during gripping, which further reduces the stability and reliability of material receiving and unloading operations. Summary of the Invention

[0006] The purpose of this invention is to provide a material receiving and unloading device applicable to all sizes and shapes, which automatically accommodates materials of various shapes and sizes, and eliminates the need for manual secondary adjustments during operation and production changeover, thereby solving the problems raised in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a full-size, multi-shape applicable material receiving and unloading device, the material receiving and unloading device including a support structure, a conveying component and a material receiving and unloading component arranged between the support structure, and an adjustment component arranged between the material receiving and unloading component and the support structure;

[0008] The material receiving and discharging assembly includes a mounting frame, which is connected to the support structure via an adjusting component. Several suction structures and several attraction structures are installed at the bottom of the mounting frame.

[0009] The suction structure includes a suction cup tube connector, a logic valve, a suction cup elastic rod, and a rubber nozzle. The logic valve is installed at the bottom of the suction cup tube connector, and the suction cup elastic rod is installed at the other end of the logic valve. A suction cup mounting rod is installed on the side of the suction cup elastic rod, and the suction cup mounting rod limits several suction structures to the same horizontal line. A rubber nozzle and a suction cup limiting tube are installed at the bottom of the suction cup elastic rod.

[0010] When the suction cup picks up material from the belt, due to the different sizes and shapes of the materials, there may not be any material covering the area under the suction cup. There is a risk that the suction cup may directly stick to the belt in the area where there is no material. In addition, some suction cups may cause the material to deform when picking up thin metal plates. However, the rubber suction nozzle of this invention will not stick to the belt, and the suction cup limiting tube at the bottom of the rubber suction nozzle prevents the suction cup from being excessively deformed, thereby achieving the purpose of foolproof.

[0011] Furthermore, the attraction structure includes a magnet frame on which a permanent magnet is disposed, and several attraction structures and several magnets are evenly installed under the mounting frame.

[0012] Different equipment is required for ferromagnetic and non-ferromagnetic materials, which increases equipment investment costs and floor space requirements.

[0013] Furthermore, the support structure includes a material receiving and discharging bracket, on which an mounting frame is installed, and a conveying assembly and a material receiving and discharging platform are installed between the material receiving and discharging brackets, with the material receiving and discharging platforms respectively located on both sides of the conveying assembly.

[0014] Existing gripping devices have only one material feeding area, which leads to serious material accumulation and affects their working efficiency during material transfer.

[0015] Furthermore, the conveying assembly includes a drive device, several drive shafts, several belt liners, a perforated belt, and a synchronizer. The drive device is connected to a set of drive shafts, and the several drive shafts are interconnected through a transmission structure. Belt liners and perforated belts are provided outside the drive shafts. The synchronizer is installed at one end of the conveying assembly. Several holes are provided on the perforated belt, and the holes are equidistantly arranged on the perforated belt.

[0016] In existing conveying devices, materials are prone to positional deviation during the conveying process due to uneven friction on the belt surface or external interference, making subsequent gripping and positioning difficult. However, the conveying component of this invention provides stable support for the perforated belt through the belt liner plate and, together with the synchronizer, ensures that the drive shaft speed is consistent, effectively preventing belt deviation and achieving precise positioning.

[0017] Furthermore, the diameter of the rubber suction nozzle is larger than the diameter of a set of holes on the perforated belt, and also larger than the center distance between two sets of adjacent holes, so that the suction cup can release pressure normally through the belt holes whenever the belt stops at any position.

[0018] Furthermore, the adjustment assembly includes a Z-axis moving module and an X-axis moving module. The X-axis moving module is installed on the material receiving and unloading bracket. The X-axis moving module cooperates with the mounting frame. An adjustment frame is installed on the mounting frame. The adjustment frame is connected to the X-axis moving module. The Z-axis moving module is provided on the adjustment frame.

[0019] The adjustment component enables flexible movement of the feeding and receiving components through X-axis and Z-axis moving modules. The lateral position can be quickly adjusted in the X-axis direction, and the lifting and lowering in the Z-axis direction is controlled by a cylinder, which can adapt to materials of different thicknesses and avoid rigid collisions, thereby improving the flexibility and automation of the operation.

[0020] Furthermore, the X-axis moving module includes two sets of limiting slide rails, and the adjusting frame is connected to the limiting slide rails through a driving device.

[0021] Furthermore, the Z-axis moving module includes an adjustment plate and several auxiliary guide rods. The fixed ends of the adjustment plate and the auxiliary guide rods are fixedly connected to the adjustment frame, and the output ends of the adjustment plate and the auxiliary guide rods are connected to the mounting frame.

[0022] Furthermore, a rubber layer is provided on the material receiving and unloading platform.

[0023] Furthermore, a lifting eye screw is provided above the material receiving and unloading bracket, and rollers are installed at the bottom of the material receiving and unloading bracket.

[0024] The lifting eye bolts on the top of the material receiving and unloading bracket can be used with a crane for lifting operations, and also facilitate handling during production; the bottom rollers are universal casters with brakes, which ensure the stability of the device when locked and facilitate movement when released, adapting to changes in site layout, reducing handling difficulty and saving labor costs.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. Through the adaptive fit design of the suction cup elastic rod and the rubber suction nozzle, it can stably grasp flat, curved and irregularly shaped materials on the planar conveying mechanism; combined with the precise adjustment of the X-axis and Z-axis moving modules, it can meet the positioning requirements of materials of different sizes and improve the adaptability of the device to diverse materials.

[0027] 2. The combination of suction structure and magnetic suction structure can handle both non-ferromagnetic and ferromagnetic materials at the same time, reducing equipment configuration costs; the optimized design of the rubber suction nozzle diameter avoids the suction cup from accidentally sucking up the belt, preventing material deformation or equipment failure.

[0028] 3. The use of perforated belts and synchronizers prevents material deviation and improves material receiving accuracy; the surface of the receiving and unloading platform is covered with a rubber layer to buffer impact and prevent slippage; the bracket is equipped with eye bolts and rollers to improve space utilization and mobility, ensuring the stability and reliability of materials throughout the entire process of conveying, grabbing and placing.

Detailed Implementation

[0037] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example: Figures 1-7As shown, the present invention provides a technical solution for a material receiving and discharging device applicable to all sizes and shapes. The material receiving and discharging device includes a support structure 1, a conveying component 2 and a material receiving and discharging component 3 are arranged between the support structures 1, and an adjusting component 4 is arranged between the material receiving and discharging component 3 and the support structure 1.

[0039] The material receiving and discharging assembly 3 includes a mounting frame 31, which is connected to the support structure 1 via an adjusting assembly 4. Several suction structures and several attraction structures are installed at the bottom of the mounting frame 31.

[0040] The suction structure includes a suction cup tube connector 32, a logic valve 33, a suction cup elastic rod 34, and a rubber suction nozzle 35. The logic valve 33 is installed at the bottom of the suction cup tube connector 32, and the suction cup elastic rod 34 is installed at the other end of the logic valve 33. A suction cup mounting rod 36 is installed on the side of the suction cup elastic rod 34. The suction cup mounting rod 36 limits several suction structures to the same horizontal line. A rubber suction nozzle 35 and a suction cup limiting tube 37 are installed at the bottom of the suction cup elastic rod 34.

[0041] Therefore, when the device is in use, when the material to be collected is transported by the conveying component 2 to the bottom of the material collection component 3, the adjusting component 4 will drive the mounting frame 31 to make precise spatial position adjustments according to the size and shape parameters of the material, so as to ensure that the suction structure and the attraction structure can be aligned with the optimal working area of ​​the material. At this time, the suction structure starts to work, the suction cup tube connector 32 is connected to the external negative pressure source, and the negative pressure is transmitted to the inside of the suction cup elastic rod 34 through the logic valve 33, so that a negative pressure environment is formed inside the rubber suction nozzle 35. Since the suction cup elastic rod 34 has good elastic deformation ability, when the rubber suction nozzle 35 contacts the material surface, it can adaptively conform to the material surface of different shapes, such as flat, curved, or even irregularly shaped surfaces with a certain curvature. At the same time, the suction cup limiting tube 37 will contact the material surface to avoid excessive compression of the rubber suction nozzle 35.

[0042] The suction cup limiting tube 37 is to limit the excessive deformation of the suction nozzle. When the rubber suction nozzle 35 is in the material shortage area and is located exactly in the middle of the two belt holes, the excessive deformation of the rubber suction nozzle 35 will cause the small hole in the middle of the rubber suction nozzle 35 to stick to the belt, and further cause the middle of the rubber suction nozzle 35 to be directly sucked to the belt. Regardless of whether the edge of the rubber suction nozzle 35 is in contact with the belt, it cannot release pressure from the two belt holes.

[0043] The suction cup mounting rod 36 ensures that the multiple suction structures are always on the same horizontal line, ensuring that the suction force on the material is evenly distributed and preventing the material from tilting or falling off during the suction process. The suction structure further assists in fixing the material while the suction structure is working. Especially for some lightweight, easily floating or uneven materials, it can effectively enhance the overall gripping stability, enabling the device to reliably perform loading and unloading operations on materials of all sizes and shapes.

[0044] like Figure 2 , Figure 6 and Figure 7 As shown, in this embodiment, specifically, the attraction structure includes a magnet frame 38, on which a permanent magnet is provided, and several attraction structures and several magnets are evenly installed under the mounting frame 31;

[0045] When the material to be picked up or put down is ferromagnetic, the permanent magnets on the magnet frame 38 generate a stable magnetic field, which continuously attracts the material. This attraction force works synergistically with the negative pressure attraction generated by the suction structure to form a double fixation. For ferromagnetic materials with a certain thickness or weight, the attraction force of the permanent magnets can share part of the material weight, reduce the load on the suction structure, and prevent the rubber suction nozzle 35 from aging and failing due to long-term excessive pressure. At the same time, even if the negative pressure of the suction structure drops slightly due to minor leakage on the material surface, the attraction force of the permanent magnets can serve as a backup guarantee to prevent the material from falling accidentally. Several suction structures and several permanent magnets are evenly installed under the mounting frame 31, making the magnetic force and attraction force more evenly distributed on the material surface. For some irregularly shaped ferromagnetic materials, stable forces can be provided from multiple points to ensure the stability of the material's posture during the picking and putting process, further expanding the device's adaptability to different materials, especially ferromagnetic materials.

[0046] like Figures 1-3 and Figure 7 As shown, in this embodiment, specifically, the support structure 1 includes a material receiving and discharging bracket 11, an mounting frame 31 is installed on the material receiving and discharging bracket 11, a conveying assembly 2 and a material receiving and discharging platform 12 are installed between the material receiving and discharging brackets 11, and the material receiving and discharging platform 12 is respectively located on both sides of the conveying assembly 2.

[0047] The material receiving / unloading support 11, as the basic load-bearing component of the entire device, is welded from high-strength steel and has excellent structural stability and load-bearing capacity. It can effectively support the weight of the conveying component 2, the material receiving / unloading component 3, and the materials to be received / unloaded, ensuring that the device will not deform or shake during long-term operation. The mounting frame 31 serves as the direct mounting carrier for the material receiving / unloading component 3. It is connected to the material receiving / unloading support 11 through the adjusting component 4, enabling flexible movement and positioning of the material receiving / unloading component 3 in space. The conveying component 2 is installed between the material receiving / unloading supports 11 to transport the materials to be received / unloaded from one end of the device to the working area of ​​the material receiving / unloading component 3, completing the material loading or unloading process.

[0048] like Figure 4As shown, in this embodiment, specifically, the conveying component 2 includes a driving device, several transmission shafts, several belt liners 21, perforated belts 22, and a synchronizer 23. The driving device is connected to a set of transmission shafts, and the several transmission shafts are interconnected through a transmission structure. Belt liners 21 and perforated belts 22 are provided outside the transmission shafts. The synchronizer 23 is installed at one end of the conveying component 2. Several holes are provided on the perforated belts 22, and the holes are equidistantly arranged on the perforated belts 22.

[0049] When the conveying assembly 2 is running, the drive unit rotates a set of drive shafts, and then transmits the power to all drive shafts through the transmission structure, causing several drive shafts to rotate synchronously. This drives the perforated belt 22, which is sleeved on the drive shafts, to transport materials smoothly. The belt liner 21 is installed inside the perforated belt 22 and fits tightly against the drive shaft, providing solid support for the perforated belt 22 and preventing it from sagging or deforming due to force during material transport, thus ensuring the flatness of the conveying surface. The design of several equally spaced holes on the perforated belt 22 has multiple advantages: on the one hand, when the material is placed on... When the material is on the perforated belt 22, some air can be discharged through the holes, reducing the air resistance between the material and the belt and making the material placement more stable. On the other hand, when working with the take-up and unload assembly 3, if the material is lightweight or has small adsorption points, the holes can prevent the formation of a sealing negative pressure between the belt and the material, which would affect the smooth release of the material. The synchronizer 23 is installed at one end of the conveying assembly 2 and can monitor and adjust the speed of the drive shafts on both sides in real time, ensuring that the material can be accurately conveyed to the predetermined position below the take-up and unload assembly 3, providing a strong guarantee for the accuracy of subsequent take-up and unload operations.

[0050] like Figure 7 As shown, in this embodiment, specifically, the diameter of the rubber suction nozzle 35 is larger than the diameter of a set of holes on the perforated belt 22, and larger than the center distance between two sets of adjacent holes, so that the suction cup can normally release pressure through the belt holes whenever the belt stops at any position.

[0051] When the rubber suction nozzle 35 picks up material from the belt, due to differences in material size and shape, there may not be material covering the area under the suction cup. In areas lacking material, there is a risk that the rubber suction nozzle 35 may stick to the belt. However, the diameter of the rubber suction nozzle 35 is larger than the distance between a set of holes on the perforated belt 22. This ensures that when the rubber suction nozzle 35 contacts the belt, its coverage area can include at least one hole. This allows the suction cup to release pressure normally through the belt hole, regardless of where the belt stops, effectively preventing the rubber suction nozzle 35 from directly sticking to the belt. At the same time, it ensures that the suction cup can fully contact the material surface in the material-covered area, forming an effective negative pressure seal and ensuring stable suction force. This size design cleverly balances the effective adsorption of material and the avoidance of belt during material picking, further improving the reliability and stability of the device when picking up and dropping materials of different sizes and shapes, and avoiding equipment failure or material damage caused by the suction cup accidentally sucking into the belt.

[0052] like Figures 1-3 and Figure 5 As shown, in this embodiment, specifically, the adjustment component 4 includes a Z-axis moving module 6 and an X-axis moving module 5. The X-axis moving module 5 is installed on the feeding and receiving bracket 11. The X-axis moving module 5 cooperates with the mounting frame 31. An adjustment frame is installed on the mounting frame 31. The adjustment frame is connected to the X-axis moving module 5. The Z-axis moving module 6 is provided on the adjustment frame.

[0053] When the adjustment component 4 is in use, the X-axis moving module 5 is installed on the receiving and discharging support 11, driving the adjustment frame to move the mounting frame 31 horizontally. The X-axis moving module 5 is only responsible for handling, while the Z-axis moving module 6 is set on the adjustment frame and drives the mounting frame 31 to rise and fall vertically, controlling the distance between the suction structure and the material. After the conveying component 2 delivers the material to the designated position, the X-axis module moves the mounting frame 31 above the material, and the Z-axis module drives it to fall so that the suction structure is close to the material. If the material height is different or needs to be placed on platforms of different heights, the Z-axis module can adjust the height of the mounting frame 31 in real time. Both the X-axis and Z-axis modules are driven by high-precision servo motors, combined with linear guides and ball screw transmission, resulting in high positioning accuracy and smooth movement, meeting the spatial adjustment needs of full-size materials.

[0054] like Figures 1-3 and Figure 5 As shown, in this embodiment, specifically, the X-axis moving module 6 includes two sets of limiting slide rails 51, and the adjusting frame is connected to the limiting slide rails 51 through a driving device;

[0055] Two sets of limit slide rails 51 are installed in parallel on the top crossbeam of the receiving and unloading support 11 to provide guidance and support for the horizontal movement of the adjustment frame. The two ends of the adjustment frame are connected to the slide rails through sliders. The sliders have built-in wear-resistant balls to reduce friction. The drive device uses a servo motor in conjunction with a synchronous belt or ball screw to drive the adjustment frame to move linearly along the slide rails. Mechanical limit blocks and photoelectric sensors are set at both ends of the slide rails to prevent overtravel collisions and provide real-time position feedback to ensure that the X-axis positioning accuracy reaches ±0.02 mm, meeting the horizontal position adjustment needs of materials of different sizes.

[0056] like Figures 1-3 and Figure 5 As shown in this embodiment, specifically, the Z-axis moving module 5 includes an adjustment plate 61 and several auxiliary guide rods 62. The fixed ends of the adjustment plate 61 and the auxiliary guide rods 62 are fixedly connected to the adjustment frame, and the output ends of the adjustment plate 61 and the auxiliary guide rods 62 are connected to the mounting frame 31.

[0057] The adjusting plate 61 is the main drive of the Z-axis, providing stable driving force to enable the rapid lifting and lowering of the mounting frame 31. The auxiliary guide rods 62 are evenly distributed around it, connecting the mounting frame 31 together to distribute the weight and prevent the adjusting plate 61 from being subjected to excessive force alone. They also extend and retract synchronously to ensure the horizontal lifting and lowering of the mounting frame 31. Both the adjusting plate 61 and the auxiliary guide rods 62 are equipped with stroke control sensors, which, together with the control system, precisely adjust the height of the mounting frame 31 to meet the docking requirements of the material picking and unloading platform 12 for materials of different thicknesses, thereby improving the vertical adjustment accuracy and operational stability.

[0058] like Figures 1-2 As shown in this embodiment, specifically, a rubber layer is provided on the material receiving and unloading platform 12;

[0059] The rubber layer on the surface of the material receiving and unloading platform 12 has multiple functions: the elasticity of the rubber material can buffer the impact of falling materials and protect fragile or delicate materials; the high surface friction coefficient can prevent materials from sliding and ensure positional stability; at the same time, it can insulate and reduce noise, and is wear-resistant and corrosion-resistant, extending the service life of the platform.

[0060] like Figure 1 As shown in this embodiment, specifically, a lifting eye screw is provided above the material receiving and discharging bracket 11, and rollers are installed at the bottom of the material receiving and discharging bracket 11;

[0061] The lifting eye screws on the top of the material receiving and unloading bracket 11 can be used with a crane for lifting operations, and also facilitate handling during production; the bottom rollers are universal wheels with brakes, which ensure the stability of the device when locked and facilitate movement when released, adapting to changes in site layout, reducing handling difficulty and saving labor costs.

[0062] Working Principle: When the material to be collected is transported by the conveying component 2 to the area below the receiving / discharging component 3, the adjusting component 4 drives the mounting frame 31 to make precise spatial adjustments based on the material's size and shape parameters. At this time, the suction structure begins to work. The suction cup tube connector 32 connects to an external negative pressure source. The negative pressure is transmitted through the logic valve 33 to the inside of the suction cup elastic rod 34, creating a negative pressure environment inside the rubber suction nozzle 35. Because the suction cup elastic rod 34 has good elastic deformation capability, when the rubber suction nozzle 35 contacts the material surface, it can adaptively conform to material surfaces of different shapes, such as flat surfaces, curved surfaces, etc. The suction cup is positioned on irregularly shaped surfaces with a certain curvature. Simultaneously, the suction cup limiting tube 37 contacts the material surface to prevent the rubber suction nozzle 35 from being over-compressed and failing in areas with insufficient material. The suction cup mounting rod 36 ensures that several suction structures are always on the same horizontal line, ensuring a uniform distribution of suction force on the material and preventing the material from tilting or falling off during the suction process. The suction structure further assists in fixing the material while the suction structure is working. Especially for some lightweight, easily floating, or uneven materials, it can effectively enhance the overall gripping stability, enabling the device to reliably handle the loading and unloading of materials of all sizes and shapes.

[0063] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
