Description

Technical Field

[0001] This application relates to the field of door and window profile production technology, and more specifically, to a symmetrical material storage bin based on position control. Background Technology

[0002] In the field of door and window profile manufacturing, the high degree of customization of doors and windows leads to a wide variety of door and window profiles. Existing technologies include numerous intelligent processing devices for processing door and window profiles to produce finished products. However, after obtaining the finished profiles, they need to be assembled to form a complete door or window. Due to the diversity of door and window types, door and window profiles also become diverse. A single initial profile often cannot be processed into a profile for a single door or window; that is, a single initial profile is often processed into door and window profiles for different doors and windows to ensure maximum material utilization. However, this method also results in a single initial profile producing door and window profiles for different doors and windows. In other words, multiple door and window profiles for different doors and windows are mixed together. Traditional manual operations require manual sorting, severely slowing down overall production efficiency.

[0003] With the development of technology, a complete set warehouse solution for door and window profiles has been proposed. A complete set warehouse refers to a storage space that provides a complete set of door and window profiles for a specific door or window. Specifically, the complete set warehouse is set up with different storage layers. Each storage layer is used to store a set of door and window profiles for a specific door or window. When assembly is required, all the complete door and window profiles for a specific door or window are taken out for subsequent assembly.

[0004] In the solution of complete door and window profile warehouse, in order to facilitate the retrieval and storage of door and window profiles and to save costs, the storage area is usually set up by using long poles to extend outward to form a placement space. However, in the existing technical solution, the long poles are usually set to be evenly distributed. This even distribution setting does not take into account the characteristics of the door and window profiles themselves and has room for improvement. At the same time, in the existing solution, the conveyor channel is designed to run continuously without intelligent control of start and stop. As a result, the door and window profiles will be intercepted or stopped at a fixed position during the conveying process, and then the retrieval and placement device will pick up and place the door and window profiles at the fixed position. Specifically, there are usually two settings. One is to set the retrieval and placement device to move in three axes and then select the placement position according to the profile. This method makes the structure of the retrieval and placement device complex and costly. Another type is a two-axis moving pick-and-place device. This method causes the door and window profiles to be concentrated at one end. Usually, this concentrated end is the end where the door and window profiles are intercepted or stopped at a fixed position during the transportation process. As a result, the weight is concentrated at one end, which can easily lead to increased bending and deformation at that end, resulting in "material slippage". Specifically, excessive deformation occurs, and under the heavy force of gravity, the door and window profiles slide to one end, then leave the storage space and fall. This situation not only affects the subsequent assembly of doors and windows, but also easily causes defects on the surface of the door and window profiles.

[0005] The above problems urgently need to be addressed. Utility Model Content

[0006] The purpose of this application is to provide a symmetrical material storage bin based on position control, which has the advantage of effectively solving the material slippage problem caused by rod deformation in the prior art.

[0007] Firstly, this application provides a location-controlled symmetrical material matching warehouse for storing and matching door and window profiles. The technical solution is as follows:

[0008] It includes at least a storage silo, on which at least one storage layer is provided, and for the at least one storage layer, there are storage rods that extend outward in a horizontal direction, which are dense in the middle and sparse at at least one end.

[0009] Furthermore, this application also includes:

[0010] Feeding channel and extraction device;

[0011] The extraction device extracts door and window profiles from the feeding channel and places them into the storage layer for storage, and extracts door and window profiles from the storage layer and places them into the feeding channel for transmission;

[0012] Also includes:

[0013] A control device, connected to the feeding channel, is used to control the start and stop of the feeding channel when conveying door and window profiles, as well as the start and stop positions, so that the start and stop positions of the door and window profiles correspond to the distribution of the storage rods on the storage layer.

[0014] Furthermore, in this application, the control device includes a control module and a servo motor. The control module is electrically connected to the servo motor to control the servo motor, and the servo motor is drive-connected to the feeding channel.

[0015] Furthermore, in this application, the control device includes a control module, a motor, and a position sensor. The control module is electrically connected to the motor and the position sensor, respectively, and is used to control the start and stop of the motor according to the position of the door and window profile detected by the position sensor. The motor is drivenly connected to the feeding channel.

[0016] Furthermore, in this application, the control device includes a control module, a position sensor, and a blocking mechanism. The control module is electrically connected to the position sensor and the blocking mechanism, respectively, and is used to control the blocking mechanism to block the door and window profiles according to the position of the door and window profiles detected by the position sensor.

[0017] Furthermore, in this application, the storage rods are symmetrically distributed in the horizontal direction, either entirely or partially, and include at least the following: the control device controls the start and stop of the feeding channel when conveying door and window profiles and the start and stop positions, so that the middle area of ​​the door and window profiles when stopped is aligned with the symmetrical center position of the storage rods in the horizontal direction, either entirely or partially.

[0018] Furthermore, in this application, the storage rods are symmetrically distributed in the horizontal direction, with the center of symmetry located at the center of the storage layer in the horizontal direction.

[0019] Furthermore, in this application, the storage rods located at the center of symmetry are densely distributed, while the distribution of the storage rods becomes sparse as they extend from the center of symmetry to both ends.

[0020] Furthermore, in this application, the storage layer of one layer includes multiple storage rods, which are distributed along the conveying direction of the feeding channel.

[0021] Furthermore, in this application, the storage rod extends in a cantilever shape toward the direction of the extraction device.

[0022] As can be seen from the above, the symmetrical material storage bin based on position control provided in this application, by setting up storage rods that are densely packed in the middle and sparsely spaced at least one end extending outward on the storage layer, makes the distribution of the storage rods compatible with the placement position of the door and window profiles. This can reduce the situation where door and window profiles are concentrated at one end of the storage space, reduce the possibility of bending and deformation of the storage rods, and effectively solve the problem of material slippage caused by rod deformation in the prior art. It has the beneficial effect of effectively solving the problem of material slippage caused by rod deformation in the prior art. Attached Figure Description

[0028] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0029] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Please refer to Figures 1 to 4 This application proposes a position-controlled symmetrical material matching warehouse for storing and matching door and window profiles. It includes at least a material storage warehouse 100, which has at least one material storage layer 110. For the at least one material storage layer 110, there are material storage rods 120 that extend outward in a horizontal direction, which are dense in the middle and sparse at at least one end.

[0031] The storage silo 100 is a component of the complete set storage system and is used for storing door and window profiles. The storage silo 100 has at least one storage layer 110 on which the door and window profiles are placed. The storage layer 110 is equipped with storage rods 120, which support the door and window profiles. The storage rods 120 extend horizontally, providing space for the door and window profiles. In a specific arrangement, the storage rods 120 exhibit a distribution pattern that is densely packed in the middle and sparsely spaced at at least one end, either overall or partially. "Densely packed in the middle" means that the distribution density of the storage rods 120 is relatively high in the middle area, with smaller spacing between the rods. "Sparsely spaced at at least one end" means that the distribution density of the storage rods 120 is relatively low in at least one end area, with larger spacing between the rods.

[0032] The storage rods 120 are arranged horizontally as follows: dense in the central area and sparse at least one end, preferably sparse at both ends. The sparse end area is to reduce costs and the number of storage rods 120. The dense middle area provides better support. At the same time, the small spacing between the storage rods 120 in the dense area allows for the placement of short profiles. That is, in some specific embodiments, short profiles will appear in the middle area instead of the two ends to avoid the weight being concentrated at the ends. Of course, in the scheme defined by the maximum protection scope of this application, it is not necessary for short profiles to be placed in the middle area, because the limitation is that at least one end is sparse, which also includes the scheme where the other end is dense. In this case, short door and window profiles can still be placed at the dense end. Furthermore, the solution in this application is limited to a horizontal orientation where the profiles are densely packed in the middle and sparsely distributed at at least one end. This includes two approaches: one where the profiles are densely packed in the middle and sparsely distributed at at least one end, and another where the profiles are densely packed in the middle and sparsely distributed at at least one end. The essence of both approaches is to ensure a good overall weight distribution for the door and window profiles, preventing excessive weight at the ends and thus material slippage. This arrangement solves the problem of unstable profile storage caused by improper arrangement of storage rods 120 in existing door and window profile storage warehouses. The dense storage rods 120 in the central area provide support for the central area of ​​the door and window profiles, distributing the weight of the profiles and preventing deformation or slippage due to their own weight. The sparse storage rods 120 at the ends avoid placing short-sized door and window profiles, reducing end weight, and together with the support in the central area, increase storage stability. The symmetrical storage warehouse embodies a balanced design, increasing storage stability.

[0033] In one implementation, the storage rods 120 are distributed in a horizontal direction with a denser distribution in the middle and a sparser distribution at both ends. That is, the density of the storage rods 120 gradually decreases from the middle to both ends.

[0034] In one implementation, the storage rod 120 is generally distributed in the horizontal direction with a dense distribution in the middle and one end, and a sparse distribution at the other end.

[0035] In one implementation, the storage rod 120 is locally distributed in the horizontal direction, with a dense distribution in the middle and a sparse distribution at both ends.

[0036] In another implementation, the storage rods 120 are locally distributed in the horizontal direction, with a denser distribution in the middle and a sparser distribution at least one end. This non-uniform distribution design of the storage rods 120 is intended to allow the weight of the door and window profiles to be more rationally distributed on the storage rods 120 when placed, preventing the door and window profiles from deforming or sliding due to the weight being concentrated at the ends.

[0037] Specifically, during operation, the door and window profiles are first placed on the storage rods 120 of the storage layer 110. Since the storage rods 120 are distributed horizontally with a denser distribution in the middle and a sparser distribution at least one end, when the door and window profiles are placed on the storage rods 120, the middle area of ​​the profiles receives support from the denser storage rods 120, while the end areas have relatively sparser distribution. This distribution allows the weight of the door and window profiles to be distributed throughout the middle area, reducing weight concentration at the ends. This reduces the risk of deformation due to the profiles' own weight and decreases the possibility of them sliding or falling, ensuring the stability of the stored door and window profiles.

[0038] In some specific embodiments, the storage layer 110 has a rectangular structure, and the storage rods 120 have a square column-shaped rod structure extending outward in the horizontal direction. The storage layer 110 is 1 meter long, and multiple storage rods 120 are arranged along its length. In the middle 0.6-meter area of ​​the storage layer 110 in the horizontal direction, a storage rod 120 is arranged every 5 centimeters; in the 0.2-meter areas on both sides, a storage rod 120 is arranged every 10 centimeters. The storage rods 120 are made of steel and have sufficient strength to support the door and window profiles. When the door and window profiles are placed on the storage rods 120, the middle area is densely supported by the storage rods 120 with smaller spacing, while the two end areas are supported by the storage rods 120 with larger spacing, achieving a dense support effect in the middle and sparse support at the ends, ensuring the stability of the door and window profile storage.

[0039] This application further proposes a feeding channel 200 and an extraction device 300; the extraction device 300 extracts door and window profiles from the feeding channel 200 and places them into the storage layer 110 for storage, and extracts door and window profiles from the storage layer 110 and places them into the feeding channel 200 for transmission; it also includes a control device connected to the feeding channel 200 for controlling the start and stop of the feeding channel 200 and its start and stop positions when conveying door and window profiles, so that the start and stop positions of the door and window profiles correspond to the distribution of the storage rods 120 on the storage layer 110.

[0040] The feeding channel 200 is configured as a conveying channel for door and window profiles, used to transport the profiles to a designated location. The extraction device 300 is configured to perform the picking and placing actions of the door and window profiles; it can grab the profiles from the feeding channel 200 and place them in the storage layer 110 for storage, and vice versa. The control device is a key component for achieving precise control of the feeding channel 200. The control device is connected to the feeding channel 200 and can precisely control the start, stop, and specific stopping position of the feeding channel 200. By controlling the stopping position of the feeding channel 200, the stopping position of the door and window profiles on the feeding channel 200 can be aligned with the stopping position on the storage layer 110. The storage rods 120 are distributed in a matching manner. For example, the storage rods 120 are densely distributed in the middle and sparsely distributed at both ends on the storage layer 110. The control device controls the start and stop of the feeding channel 200 so that when the door and window profiles stop, the middle area of ​​the door and window profiles can be aligned with the relatively dense area of ​​the storage rods 120. Thus, the stopping position of the door and window profiles on the feeding channel 200 can be adjusted according to the arrangement of the storage rods 120 and the size of the door and window profiles, so that the door and window profiles will not always stay at the fixed end of the feeding channel 200. This realizes the flexible adjustment of the placement position of the door and window profiles and makes the weight distribution of the material on the storage layer 110 more balanced.

[0041] Specifically, addressing the problem in existing technologies where materials tend to concentrate at a fixed end position, leading to bending, deformation, or even slippage, this application adds a control device to achieve precise control of the start and stop positions of the feeding channel 200. When door and window profiles need to be placed on the storage layer 110, the control device controls the feeding channel 200 to stop at an appropriate position during the conveying process, rather than running continuously. This is based on the distribution of the storage rods 120 on the storage layer 110, ensuring that the stopping position of the door and window profiles on the feeding channel 200 corresponds to the distribution of the storage rods 120 on the storage layer 110. Therefore, when the extraction device 300 extracts the door and window profiles at the stop position of the feeding channel 200 and places them on the storage layer 110, the position of the door and window profiles on the storage layer 110 can match the distribution of the storage rods 120. This avoids the door and window profiles always being concentrated at a certain fixed end, making the weight distribution of the door and window profiles on the storage layer 110 more uniform. This reduces the risk of bending deformation and slippage caused by weight concentration, ensures the stability of the door and window profile storage, facilitates the subsequent assembly of doors and windows, reduces the occurrence of defects on the surface of the door and window profiles, and this solution does not require the extraction device 300 to have three-axis movement capability.

[0042] In some specific embodiments, the feeding channel 200 can be configured as a roller conveyor, belt conveyor, etc., and the extraction device 300 can be configured as a robotic arm, suction cup, forklift-like device, etc. The control device can be a PLC controller, combined with encoders, sensors, and other components, to achieve precise control of the start and stop positions of the feeding channel 200. For example, the storage rods 120 on the storage layer 110 have a symmetrical distribution that is dense in the middle and sparse at both ends. When placing door and window profiles, the control device controls the movement of the feeding channel 200, and the encoder detects the movement of the feeding channel 200. With a movement distance of 0, when the center position of the door and window profile is detected to be aligned with the symmetrical center position of the storage layer 110, the control device controls the feeding channel 200 to stop moving. At this time, the extraction device 300 starts, extracts the door and window profile from the feeding channel 200 and places it on the storage layer 110. Since the center position of the door and window profile is aligned with the dense area of ​​the storage rods 120 and the two ends are aligned with the sparse area of ​​the storage rods 120, the weight of the door and window profile can be more evenly distributed on the storage rods 120, reducing the risk of bending deformation and slippage.

[0043] This application further proposes a control device including a control module and a servo motor. The control module is electrically connected to the servo motor to control the servo motor, and the servo motor is drive-connected to the feed channel 200.

[0044] The control device includes a control module and a servo motor. The control module issues control commands, while the servo motor receives these commands and executes precise movements. The control module and servo motor are electrically connected to transmit signals; the electrical signals from the control module control the servo motor's operating state, such as start, stop, speed, and position. The servo motor is connected to the feeder 200 via a transmission system, transmitting its power output to drive the feeder 200. The servo motor is characterized by high control precision and fast response. The control module and servo motor work together to achieve precise control of the feeder 200.

[0045] Specifically, to address the issue of inaccurate control of the feeding channel 200, a combination of a control module and a servo motor is used. The control module issues commands, which are transmitted to the servo motor. The servo motor operates precisely according to the commands, driving the feeding channel 200 to the predetermined position. Due to the precise positioning of the servo motor, the feeding channel 200 can accurately stop at the position corresponding to the distribution of the storage rods 120, ensuring that the door and window profiles are accurately placed on the storage rods 120. This improves the accuracy of storing and retrieving door and window profiles, and enhances storage efficiency. Compared to using ordinary motors or other control methods, the servo motor provides more precise position control of the feeding channel 200, ensuring the reliability and efficiency of the entire kitting warehouse operation.

[0046] In some specific embodiments, the feeding channel 200 is a roller conveyor line, and the servo motor is connected to the drive roller of the roller conveyor line. The control module can specifically be an encoder that can communicate with the production and processing system and receive the operating data of the servo motor. This allows it to calculate the specific position of the door and window profiles in real time. When the desired position is reached, the control module controls the servo motor to stop. Thus, the roller conveyor line stops accurately at the required position, and the door and window profiles also stop at the position corresponding to the distribution of the storage rods 120, facilitating subsequent storage or retrieval operations.

[0047] In other embodiments, this application proposes a control device including a control module, a motor, and a position sensor. The control module is electrically connected to the motor and the position sensor respectively to control the start and stop of the motor according to the position of the door and window profile detected by the position sensor. The motor is drivenly connected to the feeding channel 200.

[0048] The position sensors are configured in various ways to detect the position of the door and window profiles. For example, the position sensors can be non-contact sensors, such as photoelectric sensors or laser sensors, which avoid direct contact with the door and window profiles, reducing the risk of wear and damage. Alternatively, the position sensors can be proximity switches, which can directly detect the displacement of the feeding channel 200 or the position of the door and window profiles. The position sensors can be installed beside or on the feeding channel 200 to monitor the position of the door and window profiles on the feeding channel 200 in real time. The control module receives position signals from the position sensors, reflecting the real-time position information of the door and window profiles. The control module is the core component of the control system and can be a PLC programmable logic controller or a microcontroller. The control module has a preset program that sets the precise position where the door and window profiles need to stop, which corresponds to the distribution of the storage rods 120 on the storage layer 110. The control module compares the received position signal with the preset precise position and generates control commands based on the comparison result. The motor, as the driving component of the feeding channel 200, is connected to the feeding channel 200 for driving its operation. The motor can be a servo motor or a stepper motor to facilitate precise position control. The control module controls the motor's start and stop according to generated control commands. When the position sensor detects that the door / window profile is approaching or has reached a preset precise position, the control module issues a stop command, the motor stops running, and the feeding channel 200 also stops moving. Thus, the door / window profile is precisely stopped at a position corresponding to the distribution of the storage rods 120.

[0049] Specifically, the position control process of the control device is as follows: First, the position sensor detects the position of the window and door profiles on the feeding channel 200 in real time and converts the position information into an electrical signal, which is then sent to the control module. Next, the control module receives the position signal and compares the received actual position with the preset target position. Then, the control module calculates the deviation value based on the comparison result and generates a corresponding control signal based on the deviation value. Following this, the control module sends the control signal to the motor driver, which precisely controls the motor's operating state according to the control signal, adjusting the speed of the feeding channel 200 or stopping it. Finally, when the position sensor detects that the window and door profiles have reached the preset position, the control module controls the motor to stop precisely, ensuring that the window and door profiles stop accurately at the position corresponding to the distribution of the storage rods 120. Through the coordinated work of the position sensor, control module, and motor, precise position control of the window and door profiles conveyed by the feeding channel 200 is achieved.

[0050] In some other embodiments, this application further proposes a control device including a control module, a position sensor, and a blocking mechanism. The control module is electrically connected to the position sensor and the blocking mechanism, respectively, to control the blocking mechanism to block the door and window profiles based on the position detected by the position sensor.

[0051] The control device is configured to include a control module, a position sensor, and a blocking mechanism. The control module, position sensor, and blocking mechanism are electrically connected. The position sensor is configured to detect the position of the door / window profile and send the position information to the control module. The control module is configured to control the action of the blocking mechanism based on the position information sent by the position sensor, causing the blocking mechanism to act at an appropriate time to stop the door / window profile at a designated position. The blocking mechanism is configured to block the door / window profile, stopping it at the designated position. Specifically, the blocking mechanism can be configured to have multiple different blocking positions, for example, by setting multiple parallel cylinders, each cylinder can be connected to a blocking plate, controlling the blocking mechanism to block the door / window profile at the corresponding position according to the specific required position. Therefore, by blocking the door / window profile through the blocking mechanism, the stopping position of the door / window profile can be more precisely controlled, and the material storage efficiency of the door / window profile is improved.

[0052] Specifically, when the door and window profiles are conveyed on the feeding channel 200, the position sensor detects the position information of the profiles in real time. The position sensor sends the detected position information to the control module. The control module receives the position information and determines whether the door and window profiles have reached the predetermined stop position. If they have reached the predetermined position, the control module sends a control signal to the blocking mechanism. Upon receiving the control signal, the blocking mechanism immediately acts to block the door and window profiles, stopping them at a precise position. Thus, the door and window profiles can be precisely stopped at the distribution positions of the storage rods 120 on the storage layer 110, facilitating subsequent storage operations.

[0053] In some specific embodiments, the position sensor is implemented as a photoelectric sensor, the material blocking mechanism is implemented as a cylinder-driven baffle, and the control module is implemented as a PLC controller. The photoelectric sensor is installed on the side of the feeding channel 200. The material blocking mechanism is installed above the feeding channel 200. When the front end of the door / window profile reaches the position of the photoelectric sensor, the photoelectric sensor sends a signal to the PLC controller. After receiving the signal, the PLC controller controls the cylinder to actuate, causing the baffle to extend and block the door / window profile from continuing to move forward. The extension speed and force of the baffle can be adjusted according to the weight of the door / window profile and the conveying speed to ensure reliable blocking.

[0054] This application further proposes that the storage rods 120 are symmetrically distributed in the horizontal direction, either as a whole or in part, including at least: a control device controls the start and stop of the feeding channel 200 when conveying door and window profiles and the start and stop positions, so that the middle area of ​​the door and window profiles when stopped is aligned with the symmetrical center position of the storage rods 120 in the horizontal direction, either as a whole or in part.

[0055] Symmetrical distribution can be achieved, for example, the number of storage rods 120 is equal on both sides of the center of symmetry. The spacing of the storage rods 120 can be symmetrical, denser in the middle area and gradually thinner towards both ends. This dense arrangement in the middle area can provide support for the weight-concentrated areas of the door and window profiles. The control device can use sensors to detect the position of the door and window profiles on the feeding channel 200. Based on the sensor feedback, the control device can start or stop the drive mechanism of the feeding channel 200. The stop position is pre-calculated or dynamically adjusted to ensure alignment. The middle area refers to the central part of the door and window profile along its length. The center of symmetry is the center point of the symmetrical arrangement of the storage rods 120. Alignment means that the door and window profiles are placed such that the central area of ​​the door and window profiles basically coincides with the center of symmetry of the storage rods 120. This alignment is important for balanced weight distribution.

[0056] It should be noted that the symmetry referred to in this application means that the structural layout on both sides is roughly the same, and does not necessarily mean very strict and precise symmetry. For example, the spacing between the storage rods 120 on both sides can be regarded as and understood as symmetry in this application if it is within a preset range. Depending on the overall size and requirements, the preset range can also be different. For example, if the preset range is 5mm, then when there is a 5mm deviation between the storage rods 120 on both sides, it can also be regarded as symmetry. Similarly, the number of storage rods 120 is also the same.

[0057] Specifically, the core idea of ​​this application is to prevent window and door profiles from slipping by ensuring balanced support. Existing solutions with uniformly distributed storage rods 120 and fixed stopping positions of the feeding channel 200 can lead to uneven weight distribution, especially when the window and door profiles are placed asymmetrically. This asymmetry can cause bending and slippage. This solution addresses the problem by symmetrically arranging the storage rods 120, especially with a denser spacing in the central area, thereby forming a more balanced support structure. This symmetrical arrangement is designed to counteract the bending tendency of the window and door profiles due to their own weight. A control device precisely manages the movement of the feeding channel 200. The control device stops the feeding channel 200 at a specific position, aligning the central area of ​​the window and door profile with the symmetrical center position of the storage rods 120. This precise alignment ensures that the weight of the window and door profile is evenly distributed on the symmetrically arranged storage rods 120. By combining the symmetrical arrangement of the storage rods 120 and the controlled alignment of the stopping position of the feeding channel 200, the system achieves stable storage of the window and door profiles, significantly reducing the risk of slippage.

[0058] In some specific embodiments, the storage rods 120 are symmetrically arranged along the horizontal direction of the storage layer 110, specifically, there are a total of 9 storage rods 120. The spacing between the storage rods 120 increases outward from the center of symmetry. For example, the distance from the center outward can be 12 cm, 36 cm, 96 cm, and 192 cm. The control system uses position sensors to detect the leading edge of the door / window profile on the feeding channel 200. When the sensor detects that the door / window profile has reached the center of symmetry, the control system sends a signal to stop the feeding channel 200, so that when the feeding channel 200 stops, the middle part of the door / window profile is aligned with the central storage rod 120. This ensures that the weight of the door / window profile is evenly distributed on the symmetrical storage rods 120, preventing bending and slippage.

[0059] This application further proposes that the storage rods 120 are densely distributed at the center of symmetry and sparsely distributed as they extend from the center of symmetry to both ends.

[0060] The symmetry center refers to the center of the storage layer 110 in the horizontal direction. The storage rods 120 are distributed around this center as an axis of symmetry. In the symmetry center region, multiple storage rods 120 are densely arranged with small spacing between them, thus forming a high support density in this area. As the position extends from the symmetry center towards the two ends, the distribution of the storage rods 120 gradually becomes sparser, and the spacing between adjacent storage rods 120 gradually increases, resulting in a relatively low support density in the end regions. As one implementation, the densely distributed area of ​​the storage rods 120 can be set as the middle third of the horizontal length of the storage layer 110, with the remaining two end regions set as sparsely distributed areas. The density and sparseness of the storage rods 120 can be achieved by adjusting the specific spacing between them. For example, the spacing of the storage rods 120 in the dense area can be set to 50 mm, and the spacing of the storage rods 120 in the sparse area can be set to 150 mm.

[0061] Specifically, when window and door profiles are placed on the storage rods 120, the middle area of ​​the profiles, typically the heavier area, falls within the densely distributed area of ​​the storage rods 120. Because the storage rods 120 are densely distributed in this area, and because these densely distributed rods are spaced close together, they are designed to support shorter profiles. Therefore, they provide sufficient support to the middle area of ​​the profiles, effectively distributing and bearing their weight, thus reducing the risk of bending and deformation in this area. Simultaneously, at the ends of the profiles, where the weight is relatively lighter, the sparse distribution of the storage rods 120 still provides sufficient support, preventing the profiles from falling. Thus, this dense-center, sparse-outward distribution of the storage rods 120 reduces the overall number of rods required while ensuring the stability of the window and door profile storage, achieving cost savings.

[0062] This application further proposes a single-layer storage layer 110 comprising multiple storage rods 120, which are distributed along the conveying direction of the feeding channel 200.

[0063] The term "multiple storage rods 120" refers to two or more storage rods 120 installed on the same storage layer 110. "Distributed along the conveying direction of the feeding channel 200" means that the arrangement direction of the multiple storage rods 120 is consistent with the direction in which the feeding channel 200 conveys the window and door profiles. Therefore, when the window and door profiles are conveyed to the storage layer 110 through the feeding channel 200, the multiple storage rods 120 can provide support for the window and door profiles along the conveying direction. As a preferred embodiment, the multiple storage rods 120 can be arranged in a parallel configuration.

[0064] Specifically, multiple storage rods 120 are provided on the same storage layer 110, and these storage rods 120 are arranged along the conveying direction of the feeding channel 200. This structural design allows the door and window profiles to be simultaneously supported by multiple storage rods 120 arranged along the conveying direction when they are conveyed to the storage layer 110 along the feeding channel 200. Specifically, the door and window profiles are usually conveyed along their length during the conveying process. By distributing multiple storage rods 120 along the conveying direction of the feeding channel 200, the door and window profiles can be directly taken out from the side and placed directly into the storage space formed by the multiple storage rods 120 without having to turn, thus improving storage efficiency.

[0065] This application further proposes that the storage rod 120 extends in a cantilever shape toward the extraction device 300.

[0066] The cantilever structure of the storage rod 120 refers to the fact that one end of the storage rod 120 is fixedly connected to the storage layer 110 of the storage silo 100, while the other end extends freely towards the extraction device 300, forming a suspended support structure. The fact that the storage rod 120 extends towards the extraction device 300 means that the free end of the storage rod 120 points towards the working area of ​​the extraction device 300. When extracting material, the extraction device 300 can approach the material along the direction of the storage rod 120 without having to bypass or cross it. This structure simplifies the movement path of the extraction device 300 and makes the extraction action more direct and efficient.

[0067] Specifically, in the material storage and retrieval system, the storage rod 120 serves as a support structure for the materials. When materials are placed on the storage rod 120, the cantilevered rod provides support, preventing direct contact between the materials and the storage layer 110 and reducing friction. Since the storage rod 120 extends towards the retrieval device 300, the retrieval device 300 can approach the materials from the free end of the storage rod 120 to perform grasping and retrieval operations. This cantilever structure facing the retrieval device 300 avoids complex operations from the side or below, reducing retrieval difficulty and improving retrieval efficiency. Simultaneously, the cantilever structure also reduces obstruction during material placement.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
