Description

Technical Field

[0001] This application relates to the field of automation control technology, and in particular to a method and apparatus for controlling the processing mechanism of a feeding machine. Background Technology

[0002] In modern industrial production, the widespread application of automated equipment has significantly improved production efficiency and product quality. As a crucial piece of equipment in manufacturing, the core function of a material feeder is to precisely cut, separate, or shape raw materials through processing mechanisms. However, with the increasing complexity and diversification of production demands, traditional material feeder control methods have gradually revealed some problems.

[0003] On the one hand, existing technologies typically rely on manually setting parameters or simple preset rules to complete processing tasks. This approach struggles to handle raw materials of different types, shapes, and materials, especially in large-scale, multi-category processing scenarios, where low classification efficiency becomes a key bottleneck restricting overall production efficiency. On the other hand, achieving automatic classification requires comprehensive consideration of multi-dimensional information such as material characteristics, processing requirements, and equipment operating status, which places extremely high technical demands on data collection, processing, and decision-making.

[0004] Furthermore, to meet the high-efficiency demands of actual production, it is necessary not only to ensure classification accuracy but also to optimize control algorithms to shorten response time and reduce unnecessary resource consumption. However, within the existing technological framework, balancing the contradiction between classification accuracy and execution efficiency remains a critical technical challenge. These issues necessitate a more intelligent and efficient solution for controlling the processing mechanism of the feeding machine. Summary of the Invention

[0005] The purpose of this application is to provide a method and device for controlling the processing mechanism of a feeding machine, which realizes automatic classification of finished products and waste materials and improves production efficiency.

[0006] To achieve the above objectives, this application provides the following solution: In a first aspect, this application provides a method for controlling the processing mechanism of a feeding machine, including: Step 101: During the feeding process, the position of the front end face of the profile is detected by a laser sensor, and the end-cutting length is calculated based on the current position of the slide table; Step 102: Control the slide table to feed the material to the saw blade position for end cutting; Step 103: After end cutting, control the slide to move backward by the distance of the cut dimension; Step 104: Control the clamps to move the profile forward by the specified cutting dimension to cut it; Step 105: When the remaining tail of the profile is in the detection wheel, check whether the profile has come out of the clamping identification roller; Step 106: If the profile comes out of the clamping recognition roller, control the slide to move forward slowly until the tail end of the profile touches the clamping recognition roller; Step 107: Calculate the remaining length of the tail material based on the position of the slide table. If the remaining length is greater than the minimum clamping length, cut again; otherwise, eject the tail material. Step 108: Control the discharge separation tray to swing left or right to separate finished products and waste materials; the waste materials are tail materials with a length less than the minimum clamping length and scrap materials generated by end cutting.

[0007] Optionally, the discharge separation tray can be controlled to swing left or right, specifically including: The discharge separation tray is driven by a cylinder to swing left or right.

[0008] Optionally, the position of the front end face of the profile is detected by a laser sensor, and the end-cutting length is calculated based on the current position of the slide table, specifically including: The position of the front end face of the profile is determined by emitting a laser beam and receiving the reflected signal using a laser sensor. Based on the current position information of the slide, the required end-cut length is calculated using the end-cut length calculation method.

[0009] Optionally, the laser sensor is located at the front end of the feeding direction to detect the position of the front end face of the profile in real time.

[0010] Optionally, the minimum clamping length is 10 mm.

[0011] Secondly, this application provides a processing mechanism control device for a feeding machine, characterized in that it includes: The positioning module is used to detect the position of the front end face of the profile and calculate the end-cut length using a laser sensor; The cutoff control module is used to control the movement of the slide table to perform cutoff. The tail material processing module is used to detect the length of the tail material and decide whether to cut or eject it; The discharge control module is used to control the oscillation of the discharge separation tray.

[0014] Optionally, the discharge control module drives the discharge separation tray to swing via a cylinder.

[0015] Optionally, the cut-off control module controls the sliding distance of the slide according to the cut-off size set by the user.

[0016] According to the specific embodiments provided in this application, the following technical effects are disclosed: This application provides a processing mechanism control method and device for a blanking machine. In this method, a laser sensor with high-precision detection capability can accurately acquire the position information of the front end face of the profile, providing reliable data for calculating the subsequent end-cutting length. Precise control of the slide table feeding to the saw blade position ensures the end-cutting operation is performed at the appropriate position, guaranteeing cutting quality. Control of the slide table's backward movement to the cutting dimension distance prepares for subsequent cutting operations. The clamps grip the profile and move forward to the cutting dimension distance for cutting, ensuring a stable and reliable process. Timely and accurate detection of whether the remaining tail of the profile has dislodged from the clamping roller. If the profile dislodges from the clamping roller, the slide table is controlled to move slowly forward until the tail of the profile touches the clamping roller, effectively avoiding cutting problems caused by profile position deviation. The remaining tail length is calculated based on the slide table position, and it is determined whether to cut again, improving material utilization. Controlling the discharge separation tray to swing left or right to separate finished products and waste materials achieves automatic classification of finished products and waste materials, improving production efficiency.

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1 like Figure 1 As shown, this embodiment provides a method for controlling the processing mechanism of a feeding machine, including: Step 101: During the feeding process, the position of the front end face of the profile is detected by a laser sensor, and the end-cutting length is calculated based on the current position of the slide table; Step 102: Control the slide table to feed the material to the saw blade position for end cutting; Step 103: After end cutting, control the slide to move backward by the distance of the cut dimension; Step 104: Control the clamps to move the profile forward by the specified cutting dimension to cut it; Step 105: When the remaining tail of the profile is in the detection wheel, check whether the profile has come out of the clamping identification roller; Step 106: If the profile comes out of the clamping recognition roller, control the slide to move forward slowly until the tail end of the profile touches the clamping recognition roller; Step 107: Calculate the remaining length of the tail material based on the position of the slide table. If the remaining length is greater than the minimum clamping length, cut again; otherwise, eject the tail material. Step 108: Control the discharge separation tray to swing left or right to separate finished products and waste materials; the waste materials are tail materials with a length less than the minimum clamping length and scrap materials generated by end cutting.

[0022] In some embodiments, when performing steps 101-108, the specific steps may be as follows: At the initial feeding stage, the laser sensor system is activated. The laser sensor, positioned at the front end of the feeding direction, emits a laser beam and receives the reflected signal to detect the position of the profile's front end face in real time. The position calculation unit in the positioning module accurately calculates the required end-cut length based on the current position information of the slide table and using the end-cut length calculation formula.

[0023] To calculate the end cut length, the following algorithm can be used: Get the current position of the slide: Read the real-time position data of the slide, denoted as (x).

[0024] Define preset parameters: Set target location .

[0025] Set safety margin This is to address potential errors or dynamic adjustment needs.

[0026] Calculate the theoretical end-cut length: ; in, This represents the theoretical cutting length from the current position to the target position.

[0027] Add a safety margin: ; Final end cut length It includes additional safety margins to ensure the reliability of the cutting operation.

[0028] Boundary condition check: if Exceeding the maximum allowable cutting length of the equipment If so, a warning will be issued and the length will be limited. .

[0029] if Less than the minimum cutting length Then adjust to .

[0030] Output result: Returns the final calculated end-cut length. .

[0031] The algorithm described above can accurately calculate the required end-cut length based on the current position information of the slide, while taking into account both safety and feasibility in practical applications.

[0032] The control system drives the slide table to smoothly feed the material along the guide rail to the saw blade position for end cutting. After the end cutting is completed, the cutting control module controls the slide table to move backward a corresponding distance according to the user-preset cutting size D (unit: millimeters). Subsequently, the clamping system is activated, clamping the profile and moving it forward a distance of cutting size D to complete the first cut.

[0033] During subsequent processing, the tail material handling module continuously monitors the profile's condition. When a remaining tail of the profile is detected, the clamping recognition roller monitors in real time whether the profile has come off. If this occurs, the system automatically controls the slide to move slowly forward at a speed of v=50mm / s until the tail of the profile accurately contacts the clamping recognition roller. The length calculation unit then calculates the remaining tail material length Lr.

[0034] When the remaining length Lr of the tail material is detected to be greater than the minimum clamping length of 10 mm, the system will automatically perform a recutting operation; if Lr is less than or equal to 10 mm, the tail material ejection program will be started to push the tail material to the discharge separation tray.

[0035] like Figure 2 As shown, the discharge control module drives the discharge separation tray to swing via a cylinder. The separation process of finished product and waste is as follows: After receiving the control signal, the cylinder pushes the discharge separation tray to swing left or right by an angle α (usually 30°-45°), effectively separating the finished product from the waste. The waste includes tail material less than 10 mm in length and scrap material generated from end cutting.

[0036] Example 2 like Figure 3 As shown, a processing mechanism control device for a feeding machine is characterized by comprising: Positioning module 301 is used to detect the position of the front end face of the profile and calculate the end-cut length using a laser sensor; The cutoff control module 302 is used to control the movement of the slide table to perform cutoff. The tail material processing module 303 is used to detect the length of the tail material and decide whether to cut or eject it; The discharge control module 304 is used to control the oscillation of the discharge separation tray.

[0037] The system also includes multiple functional modules. The positioning module 301 achieves precise positioning through a laser sensor and a position calculation unit; the tail material processing module 302 uses a clamping identification roller and a length calculation unit to detect and calculate the length of the tail material; the discharge control module 303 uses a cylinder to drive the discharge separation tray to swing so as to discharge the material; and the cutting control module 304 precisely controls the movement distance of the slide according to the cutting size set by the user, thereby completing the cutting operation.

[0038] In summary, this application has the following technical effects: The processing mechanism control method and device of the feeding machine provided in this application realizes the automation and intelligence of the feeding machine processing process through a precise positioning module, an efficient cutting control module, an intelligent tail material processing module, and a flexible discharge control module.

[0039] The positioning module utilizes a laser sensor to detect the position of the profile's front end face in real time and, combined with the current position information of the slide table, accurately calculates the required end-cutting length, providing accurate data support for subsequent cutting operations. The cutting control module precisely controls the slide table's movement distance according to the user-preset cutting dimensions, ensuring the accuracy and efficiency of the cutting operation. The tail material handling module continuously monitors the profile's condition during processing. When it detects remaining tail material, it automatically determines the remaining length and decides whether to perform further cutting or ejection, effectively avoiding waste. The discharge control module uses a cylinder to drive the discharge separation tray to swing, achieving effective separation of finished products and waste materials, improving discharge efficiency and cleanliness. Therefore, this application not only improves the processing accuracy and efficiency of the blanking machine but also reduces the labor intensity of operators, demonstrating significant technical and economic benefits.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
