Description

Technical Field

[0001] The present invention relates to the field of profile storage, and in particular to a storage device for conveying profile rods into a warehouse and a working method thereof. Background Art

[0002] In a profile production line, the production of window and door frames involves multiple steps. After cutting and processing, the profiles need to be temporarily stored to facilitate subsequent processes such as sorting and framing. A material warehouse, serving as an intermediate storage link, ensures smooth transitions between processes and avoids production stalls caused by varying process speeds. For example, profiles produced quickly by cutting and processing equipment can be stored in the warehouse until they become available in subsequent processes, ensuring the continuity of the entire production line.

[0003] A Chinese patent (publication number CN 222388869 U, publication date 20250124) discloses a profile storage device. Considering that the glue on the external packaging tape of the profile will cause the profile to skew during transportation, if it is directly put into storage without correction, it is easy to cause interference and slipping of the profile, increasing the risk of mechanical failure. Therefore, the storage equipment in its material warehouse has a correction function. The profile correction unit can be used to correct the posture of the profile to ensure smooth storage and storage stability of the profile, thereby improving the stability and safety of the entire production process. However, it only considers the convenience and efficiency during storage. When taking out of the warehouse, due to the different lengths of the profiles, the relative position between the profiles placed in the warehouse and the side of the warehouse for taking out of the warehouse is not fixed. For the profiles whose ends are still retracted in the side for taking out of the warehouse, it is difficult for the corresponding operators and operating equipment to quickly locate and grasp them, which increases the time for finding and adjusting the grasping position, reduces the production rhythm, and affects the overall efficiency of the production line. In addition, since the position of the profiles after entering the warehouse is not controlled, it is difficult to locate them when taking them out. For plastic profiles, the ends of the rods obtained after processing are relatively fragile. When probing into the warehouse for taking them out, it is easy to cause the profile rods to shake and collide, damaging the surface of the profile rods, affecting the appearance and dimensional accuracy of the product, and causing a decline in product quality. Summary of the Invention

[0004] The purpose of the present invention is to address the defects of the prior art and provide a storage device and working method for conveying and storing profile rods into the warehouse. The rods are grabbed, transported and position-adjusted by the transfer component on one side of the loading end of the warehouse, so that the rods can be accurately loaded into the warehouse, and the position of the rods can be adjusted by the pushing mechanism after the rods are loaded into the storage grid, so that one end of the rods can be extended beyond the unloading end of the storage grid, so that when the downstream takes the rods, the part of the rods that protrudes out of the storage grid can be directly grabbed, and there is no need to probe into the storage grid to perform identification and positioning in the narrow space. When the rods are taken out of the warehouse, the protruding unloading end is used as a unified and obvious mark. Whether it is manual operation or automated equipment operation, the grabbing operation can be performed more conveniently, which improves the convenience and smoothness of operation.

[0005] The first object of the present invention is to provide a storage device for transporting and storing profile rods, which adopts the following scheme:

[0006] include:

[0007] The material storage includes a material storage grid arranged in an array, with both ends of the material storage grid open, one end serving as a loading end and the other end serving as a unloading end;

[0008] The transfer assembly includes a robotic arm and a clamping mechanism and a pushing mechanism located at the end of the robotic arm. It is arranged on the side of the material storage close to the loading end. The clamping mechanism is provided with a clamping part for clamping the rod, so that the rod can be loaded into the storage grid under the drive of the robotic arm; the pushing mechanism is used to push the rod in the storage grid to adjust the relative position of the rod and the unloading end, so that one end of the rod protrudes out of the unloading end.

[0009] Furthermore, it also includes a conveyor platform to supply rods to the transfer assembly. The conveyor platform includes a conveyor belt and a conveyor roller. The conveyor belt carries the rods and runs in a first direction. The conveyor roller is equipped with a lifting mechanism. The conveyor roller utilizes the lifting and lowering movement of the lifting mechanism to protrude or recess into the area where the conveyor belt carries the rods. The conveyor roller carries the rods and runs in a second direction. The first direction and the second direction are distributed at an angle.

[0010] A second object of the present invention is to provide a method for the storage device for transporting and storing profile rods as described in the first object, comprising:

[0011] The robotic arm drives the clamping mechanism to adjust its position and grab the rods to be stored in the warehouse;

[0012] The robotic arm drives the rod to slide into the storage compartment through the loading end of the storage compartment, and releases the clamping after the rod is stably placed in the storage compartment;

[0013] According to the length relationship between the rod and the storage grid after loading, the robotic arm drives the pushing mechanism to push the rod to adjust its position. One end of the rod protrudes out of the unloading end of the storage grid and is clamped when waiting to be used.

[0014] The robotic arm drives the clamping mechanism and the pushing mechanism to reset and load the next rod to be stored in the material warehouse.

[0015] Furthermore, when the rods are loaded into the material warehouse, the rods constituting the same frame are arranged in sequence on the same layer or in the same column.

[0016] Furthermore, when the rods are loaded into the material warehouse, the rods constituting different frames are loaded into the material warehouse in sequence according to the direction from the bottom storage compartment to the top storage compartment of the material warehouse.

[0017] Furthermore, the length of the rod clamped by the clamping mechanism is obtained, and the operation of the pushing mechanism is controlled based on the dimensional relationship between the length of the rod and the distance between the two ends of the material storage grid.

[0018] Furthermore, after the rod is loaded onto the material storage grid, the rod is pushed so as to be retracted into the loading end.

[0019] Furthermore, the pushing mechanism is a telescopic rod. When the clamping mechanism clamps the rod to load the material into the material storage grid, the pushing mechanism remains in a contracted state, so that the pushing mechanism and the material storage are kept spaced apart.

[0020] Furthermore, the clamping portion of the clamping mechanism clamps the middle portion of the rod.

[0021] Furthermore, the clamping mechanism and the pushing mechanism are spaced apart. After the clamping mechanism loads the plurality of rods, the pushing mechanism operates to push the rods in the storage grid to adjust their positions.

[0022] Compared with the prior art, the present invention has the following advantages and positive effects:

[0023] In order to solve the problem of low warehouse-out efficiency caused by the difficulty in positioning and grasping the rods after they are put into the warehouse, the rods are grasped, transferred and position-adjusted through the transfer component on the loading end of the warehouse, so that the rods can be accurately loaded into the warehouse. In addition, the position of the rods can be adjusted by the pushing mechanism after the rods are loaded into the storage grid, so that one end of the rods can be extended beyond the unloading end of the storage grid. When the downstream takes the rods, the part of the rods that protrudes out of the storage grid can be directly grasped, and there is no need to reach into the storage grid to perform identification and positioning in the narrow space. When the rods are taken out of the warehouse, the unloading end is used as a unified and obvious mark. Whether it is manual operation or automated equipment operation, the grasping operation can be performed more conveniently, which improves the convenience and smoothness of operation.

[0024] Compared to traditional storage and warehousing processes, this invention facilitates integration with a wide variety of subsequent processing equipment through standardized access methods. Different equipment can be designed with unified gripping interfaces or operating procedures based on the rod protruding from the blanking end, enhancing compatibility and synergy across the entire production system. This reduces time lost due to positioning difficulties, avoids losses caused by reduced product quality, improves production efficiency, and reduces time costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Example 1

[0030] In a typical embodiment of the present invention, Figure 1-Figure 2 As shown, a device for transporting and storing profile rods into a warehouse is provided.

[0031] In the prior art, the position of profiles in the material warehouse 1 is not fixed, especially when the end is retracted to the side for outbound access, making it difficult for operators and equipment to quickly locate and grasp them. Since the position of the profiles after storage is not controlled, positioning is difficult when accessing them. For plastic profile rods 4 with fragile ends, reaching into the material warehouse 1 to grasp them can easily cause shaking and collision, damaging the surface of the rods 4 and affecting product quality. Based on this, this embodiment provides a storage device for conveying profile rods into the warehouse. The push mechanism of the transfer component adjusts the position of the rods 4 so that one end of the rods 4 protrudes from the discharge end 3. This eliminates the need to reach into the interior of the material warehouse 1 when accessing, thus avoiding such damage.

[0032] Specifically, such as Figure 1 As shown, the storage device for conveying profile rods into the warehouse is mainly composed of a material warehouse 1 and a transfer component. The two work together to solve the problem of storing and taking out the rods 4, and work closely with the upstream and downstream structures in the production line to ensure a smooth production process.

[0033] The material warehouse 1 includes material storage grids 2 distributed in an array, such as Figure 1As shown, the storage compartments 2 on the material warehouse 1 are arranged in a rectangular array. In other optional embodiments, the arrangement of the storage compartments 2 on the material warehouse 1 can also be configured according to needs. The storage compartments 2 are open at both ends, one end is the loading end 6, and the other end is the unloading end 3, which facilitates the entry and exit of the rods 4. The array arrangement helps to improve space utilization and facilitates the classified storage of profile rods 4 of different specifications.

[0034] The transfer assembly consists of a robotic arm and a clamping mechanism and a pushing mechanism at the end of the robotic arm. The robotic arm can move flexibly, driving the clamping mechanism to grab the profile rod 4 and send it into the storage compartment 2 through the loading end 6 of the storage compartment 2; the pushing mechanism is used to adjust the position of the rod 4 in the storage compartment 2 so that one end of it protrudes from the unloading end 3. This solves the problem of the rod 4 being in an unstable position and difficult to access after being stored in the prior art. It avoids the situation where the end of the rod 4 is retracted in the warehouse, making it difficult for operators and equipment to locate and grab it; at the same time, it prevents shaking and collision caused by reaching into the warehouse 1 to grab the fragile plastic profile rod 4 when taking it, protects the surface of the profile rod 4, and ensures product quality.

[0035] Specifically, the transfer assembly is mainly used to realize the grabbing, transfer and position adjustment of the profile rod 4, and the robotic arm, clamping mechanism and pushing mechanism can be adaptively configured according to needs.

[0036] For example, the robotic arm can be a multi-jointed one, similar to the six-axis robotic arms commonly used in industry. It features multiple rotational and telescopic joints, enabling flexible movement within space, achieving three-dimensional displacement and posture adjustment. Based on pre-programmed commands or instructions from a control system, the robotic arm can precisely control its trajectory, reaching a designated location to grasp and place the profile rod 4.

[0037] The clamping mechanism is mounted at the end of the robotic arm and utilizes pneumatic or electric jaws. These jaws can be designed as split jaws with anti-slip rubber pads or toothed structures inside to enhance grip on the profile rod 4 and prevent it from slipping during transport. The jaws' opening and closing are driven by a pneumatic cylinder or motor. By controlling the air pressure or current, the gripping force can be adjusted to accommodate profile rods of varying sizes and materials.

[0038] The pushing mechanism consists of a linear guide, a slider, an electric push rod, and a push plate. The linear guide and slider are mounted at the end of the robotic arm near the clamping mechanism, providing stable linear motion guidance for the pushing action. The electric push rod is fixed to the slider, with its telescopic end connected to the push plate. When the position of the profile rod 4 needs to be adjusted, the electric push rod is activated, pushing the push plate forward. The push plate contacts the rod 4 within the storage compartment 2 and pushes it toward the unloading end 3 of the storage compartment 2, causing one end of the rod 4 to protrude beyond the unloading end 3. The pushing distance can be precisely adjusted by controlling the telescopic length of the electric push rod.

[0039] By configuring the transfer component, the position of the rod 4 after loading can be adjusted so that it can be in a state that is convenient for the retrieval equipment to grab, thereby improving the efficiency of retrieval of the rod 4, reducing the time for finding and adjusting the grabbing position, and speeding up the production rhythm; improving the overall efficiency of the production line and enhancing the stability of production; standardized storage and retrieval methods facilitate connection with upstream and downstream equipment, and reduce production costs.

[0040] The structure connected upstream of the transfer assembly is usually a profile processing equipment. The processed rod 4 is directly transported to the vicinity of the transfer assembly, waiting to be grabbed by the transfer assembly. In this embodiment, a conveyor platform is configured to carry the rod 4 obtained after processing by the profile processing equipment. The conveyor platform supplies the rod 4 to the transfer assembly. The conveyor platform includes a conveyor belt 7 and a conveyor roller 8. The conveyor belt 7 carries the rod 4 and runs along the first direction 9. The conveyor roller 8 is equipped with a lifting mechanism. The conveyor roller 8 uses the lifting movement of the lifting mechanism to protrude or recess into the area where the conveyor belt 7 carries the rod 4. The conveyor roller 8 carries the rod 4 and runs along the second direction 10. The first direction 9 and the second direction 10 are distributed at an angle.

[0041] In this embodiment, the conveyor belt 7 is mainly responsible for carrying the rod 4 and running along the first direction 9, playing the role of preliminary conveying of the rod 4, continuously conveying the rod 4 from the upstream connecting structure to the position near the transfer component, realizing long-distance conveyance of the rod 4, and ensuring that the transfer component has a stable supply of rods 4.

[0042] The conveyor rollers 8 work in conjunction with a lifting mechanism. When the direction of the rod 4 needs to be changed, the lifting mechanism activates, causing the conveyor rollers 8 to protrude from the conveyor belt 7's load area, lifting the rod 4. The conveyor rollers 8 can now carry the rod 4 in a second direction 10, precisely positioning the rod 4 for the transfer assembly. When the conveyor rollers 8 are not needed, they can be recessed into the conveyor belt 7, maintaining proper transport of the rod 4. The first and second directions 9, 10 can be arranged perpendicularly or at varying angles to meet site requirements, enabling the conveyor platform to flexibly adjust the rod 4 transport path to meet diverse production layouts and process requirements.

[0043] The robotic arm drives the clamping mechanism to grab the profile rod 4 to be stored conveyed by the conveyor table, slides it into the storage compartment 2 through the loading end 6 of the storage compartment 2, and releases the clamping after the rod 4 is stably placed; then, according to the length of the profile, the robotic arm drives the pushing mechanism to push the rod 4 so that one end of it protrudes out of the unloading end 3 of the storage compartment 2; then the robotic arm drives the clamping mechanism and the pushing mechanism to reset, preparing to process the next profile rod 4 to be stored.

[0044] The downstream equipment connected to the material storage 1 can be various processing or assembly equipment. When the profile is needed, the downstream equipment can directly grab the profile rod 4 that has been protruded from the unloading end 3 of the material storage grid 2 for subsequent processing or assembly operations.

[0045] Example 2

[0046] In another typical embodiment of the present invention, Figure 1-Figure 2 As shown, a working method of a device for conveying and storing profile rods into a warehouse is provided, and the device for conveying and storing profile rods into a warehouse is constructed as in Example 1.

[0047] A working method of a device for conveying and storing profile rods into a warehouse, comprising:

[0048] The robotic arm drives the clamping mechanism to adjust its position and grabs the rod 4 to be stored in the material warehouse 1;

[0049] The robotic arm drives the rod 4 to slide into the material storage grid 2 through the loading end 6 of the material storage grid 2, and releases the clamping after the rod 4 is stably placed in the material storage grid 2;

[0050] According to the length relationship between the rod 4 and the material storage grid 2 after loading, the robot arm drives the pushing mechanism to push the rod 4 to adjust the position. One end of the rod 4 protrudes out of the unloading end 3 of the material storage grid 2 and is clamped when waiting to be used.

[0051] The robotic arm drives the clamping mechanism and the pushing mechanism to reset, and loads the next rod 4 to be stored in the material warehouse 1.

[0052] Specific, combined Figure 1 and Figure 2 , the working method of the storage device for conveying profile rods into the warehouse is explained in detail.

[0053] The robotic arm drives the clamping and pushing mechanisms to complete a series of actions, ensuring the precise loading and position adjustment of the rod 4. The robotic arm drives the clamping mechanism to grasp the rod 4, which then slides through the loading end 6 of the storage compartment 2. This ensures that the rod 4 is accurately placed in the storage compartment 2 and releases the clamp after it is stably placed, preventing the rod 4 from falling or being placed improperly.

[0054] like Figure 1 As shown, the position is adjusted according to the length relationship between the rod 4 and the storage grid 2 so that one end protrudes out of the unloading end 3, which is convenient for subsequent use. Both manual and automated equipment can quickly locate and grasp, thereby improving production efficiency.

[0055] According to the arrangement rule of the rods 4 configured in the material warehouse 1, the rods 4 constituting the same frame are arranged in sequence on the same layer or in the same column, which facilitates quick finding of the relevant rods 4 during subsequent retrieval and assembly, reduces the searching time, and improves the assembly efficiency; the rods 4 constituting different frames are loaded in sequence from the bottom layer to the top layer of the material warehouse 1, which makes the storage of the material warehouse 1 more orderly, facilitates management and inventory statistics, and also conforms to the habit of general production lines to retrieve from bottom to top or in sequence, further optimizing the production process.

[0056] Obtain the length of the rod 4 clamped by the clamping mechanism, and control the operation of the pushing mechanism based on the dimensional relationship between the length of the rod 4 and the distance between the two ends of the storage grid 2, so as to achieve precise position adjustment and ensure that rods 4 of different lengths can be extended to the appropriate length outside the unloading end 3 of the storage grid 2, which is convenient for access and avoids extending too long to affect other operations.

[0057] To precisely adjust the position of the push mechanism based on the length of the rod 4 and the distance between the two ends of the storage compartment 2, the length of the rod 4 can be first acquired. A laser distance sensor can then be installed on the clamping mechanism. When the clamping mechanism grasps the rod 4, the sensor emits a laser beam toward both ends of the rod 4. By measuring the time it takes for the laser to reflect back, the distance from the sensor to the ends of the rod 4 is calculated, and the length of the rod 4 can be determined. This method is highly accurate and fast, allowing accurate rod 4 length data to be obtained in a short period of time.

[0058] The detected length data of the rod 4 is transmitted to a controller, such as a programmable logic controller (PLC) or an industrial computer. The controller pre-stores the information of the distance between the two ends of the storage grid 2. After receiving the length data of the rod 4, the controller calculates the distance that the pushing mechanism needs to push according to the preset algorithm. The algorithm can be set according to actual needs, such as ensuring that the length of the rod 4 protruding from the blanking end 3 is a fixed value, or adjusted according to a certain ratio. The standard pushing distance data of rods 4 of different specifications are stored in the controller's database. After obtaining the actual length of the rod 4, the controller compares it with the standard data, quickly obtains the operating parameters of the pushing mechanism, and improves processing efficiency.

[0059] In this embodiment, the push mechanism is a linear module driven by an electric push rod. Based on the calculation results, the controller sends a control signal to the motor, controlling the rotation angle and speed of the motor inside the push rod. The motor drives the lead screw or belt, which in turn pushes the rod 4 a set distance.

[0060] After loading, the rod 4 is pushed and retracted within the loading end 6, preventing it from protruding beyond the loading end 6 and potentially affecting subsequent loading operations or creating safety hazards, ensuring a smooth and safe loading process. The push mechanism utilizes a telescopic rod that remains retracted during loading and spaced from the material reservoir 1. This prevents interference with the loading process caused by the push mechanism, preventing collisions and other issues, and ensuring stable loading.

[0061] The clamping mechanism clamps the middle part of the rod 4, which can better balance the weight of the rod 4, keep the rod 4 stable during transportation, reduce the risk of shaking and falling, and improve the safety and accuracy of transportation.

[0062] The clamping mechanism and the pushing mechanism are distributed at intervals. After the clamping mechanism loads multiple rods 4, the pushing mechanism operates to adjust the position, avoiding conflicts that may arise from the simultaneous operation of the two mechanisms, improving the coordination and stability of the device operation, and also facilitating the control and management of each operation link.

[0063] In addition, if Figure 1 As shown, the ends of the rods 4 that extend beyond the blanking end 3 can also be aligned. This alignment ensures that the protruding portions of all rods 4 are aligned. Operators or automated equipment no longer need to adjust the gripping position one by one when grasping. They can simply reach out or activate the gripping device to grasp accurately, greatly saving retrieval time and speeding up production. In door and window manufacturing production lines, workers can quickly grab profiles for assembly, reducing waiting time and improving work efficiency. The fast and accurate retrieval process reduces the production line's downtime caused by waiting for materials, making the connection between various production links closer, the material supply smoother, and enhancing the continuity and overall operational efficiency of the production line.

[0064] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
