[0002] Currently, CNC machine tools and other processing equipment generate large amounts of waste, including chips and dust, during operation. This waste not only affects processing efficiency but can also damage the equipment, such as clogging cooling systems and damaging precision components. It also increases operator safety risks and can cause environmental pollution.

[0003] However, traditional methods for handling this waste primarily involve manual cleaning and simple automatic chip removal systems, but these methods have numerous limitations. Manual cleaning is labor-intensive and inefficient, and frequent manual intervention can introduce safety hazards. While simple automatic chip removal systems alleviate the manual burden to some extent, they lack precise monitoring and control methods, resulting in a low degree of automation and often being unable to cope with fluctuations in waste volume. This can lead to untimely or excessive chip removal, which in turn affects equipment stability and efficiency. Summary of the Invention

[0055] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0056] like Figure 1As shown, one embodiment of the present invention provides a chip collection device, which includes a conveying part, a dust collecting part, a weight detection part and a control part. At least a part of the conveying part is movably arranged, and the conveying part has a bearing surface for bearing waste chips. The dust collecting part is arranged on one side of the conveying part, and the dust collection port of the dust collecting part is arranged toward the bearing surface for sucking up flying waste chips. The weight detection part is arranged on the conveying part and is used to detect the weight of the waste chips on the conveying part. The conveying part, the dust collecting part and the weight detection part are all connected to the control part to control the moving speed of at least part of the conveying part and the air volume of the dust collecting part according to the detection result of the weight detection part.

[0057] In a chip collection device provided by one embodiment of the present invention, a weight detection element can detect changes in the weight of waste chips on the support surface in real time, providing accurate data input to the control element, enabling the device to intelligently respond to the state of waste chip accumulation. At least a portion of the conveying portion is movably arranged, and the control element can automatically adjust its movement speed based on the detection results of the weight detection element, thereby ensuring timely and efficient transportation of waste chips and avoiding the problem of low transportation efficiency caused by waste chip accumulation. At the same time, a dust collection element is arranged on one side of the conveying portion, and its dust collection port is arranged toward the support surface. The control element can adjust the air volume of the dust collection element in real time based on the weight of the waste chips on the support surface, ensuring sufficient suction when the amount of waste chips is large, while reducing energy waste when the amount is small, thereby achieving optimization of dust collection effect and resource utilization. The control element is connected to the conveying portion, the dust collection element, and the weight detection element, and can automatically control the movement speed of the conveying portion and the air volume of the dust collection element based on the real-time detection results, reducing manual intervention and improving the automation level and production efficiency of the device. By dynamically adjusting the air volume of the dust collecting element, waste chip splashing and dust are effectively controlled, pollution to the working environment is reduced, and healthier and safer working conditions are provided for operators. Therefore, the chip collection device provided by this embodiment can solve the problem of low automation level of chip collection devices in the prior art.

[0058] Specifically, the weight detection element is a load cell. The conveyor unit includes a support structure and a conveyor member, which is movably mounted on the support structure and forms at least a portion of the conveyor unit. The load cell is integrated into the bottom of the support structure and monitors the total mass of the waste chips in real time. Specifically, the conveyor member is a conveyor belt. The conveyor belt is made of high-strength rubber material with high wear resistance. The surface is antistatic to prevent metal chips from being attracted to the belt due to static electricity, thereby improving conveying efficiency.

[0059] Specifically, the conveyor section can be a chain conveyor belt structure, which is composed of a series of connected chain links with a metal plate support surface formed by clamping between the chain links. It is suitable for carrying heavy or sharp-edged waste chips, such as large metal chips or casting residues. The conveyor section can also be a rubber conveyor belt structure, which is suitable for transporting lighter waste chips, such as metal powder, wood chips, or plastic chips. The conveyor section can also be a scraper conveyor, which is equipped with multiple scrapers arranged along the conveying direction. It is suitable for transporting waste chips generated by wet operations, such as metal chips with coolant.

[0060] Specifically, the chip collection device is used to collect waste chips generated by the machine tool during the cutting process. The conveying part is arranged at the bottom of the machine tool, and the dust collecting part is located on the side of the machine tool, which uses the negative pressure principle to absorb metal chips in the surrounding air. With such a structural setting, the reasonable layout of the conveying part and the dust collecting part can effectively collect the waste chips generated by the machine tool during the cutting process, prevent the waste chips from accumulating in the working area, ensure the continuous and stable operation of the machine tool, and improve the processing efficiency. The conveying part is placed at the bottom of the machine tool, which can capture and collect the waste chips generated by the processing in the first time, reduce the physical path of the waste chips from the generation point to the collection point, and simplify the process of waste chip treatment. The dust collecting part is arranged on the side of the machine tool to ensure that the dust collection range covers the main waste chip generation sources of the machine tool, and improves the comprehensiveness and effectiveness of waste chip collection.

[0061] Specifically, multiple machine tools can share a single chip collection device. This structural setup allows multiple machine tools to share the same chip collection device, reducing the equipment cost required for each machine tool. This also facilitates centralized waste chip processing, unified management and maintenance of the chip collection device, reducing the manpower and time required to individually handle waste chips from each machine tool, and improving the overall operational efficiency of the factory. Sharing a chip collection device across multiple machine tools reduces the number of waste chip processing facilities, optimizes the spatial layout of the workshop, promotes the rational allocation and utilization of resources, and enhances the consistency and coordination of the production process.

[0062] Specifically, the control unit uses a PLC controller (programmable logic controller) with an automatic alarm function. It can predict the amount of waste chips generated based on historical data and real-time sensor data, and optimize the waste chip processing process. When the chip collection box used to collect waste chips transported by the conveying unit is about to be full, the control unit will sound an alarm and stop the operation of the conveying unit. The control unit also provides a human-machine interface, which is connected to the cloud platform. The operator can remotely monitor the status of the device through a mobile phone or computer and receive fault alarm information. The control unit can automatically adjust the conveyor belt speed, the air volume of the dust collection unit and other parameters according to the characteristics of the different processing materials processed by the machine tool (such as metal type, processing method), to achieve intelligent operation. In addition, the control unit has a built-in fault self-diagnosis function that can automatically identify and locate the fault point, provide maintenance suggestions, and reduce downtime.

[0063] In one embodiment, the conveying portion includes a first conveying section, a second conveying section, and a third conveying section that are connected in sequence. The first conveying section, the second conveying section, and the third conveying section are all extended along a preset direction. The inlet end of the first conveying section is connected to a chip outlet for discharging chips to a bearing surface, and the outlet end of the third conveying section is connected to a chip collecting chamber for collecting waste chips. The first conveying section, the second conveying section, and the third conveying section are all connected to a control member, and the control member is used to control the moving speed and moving direction of any one of the first conveying section, the second conveying section, and the third conveying section.

[0064] With this structural setup, the first, second, and third conveyor sections can each independently control their speed and direction, with the control unit managing them uniformly. This modular design allows the system to fine-tune the chip transfer path and speed based on the chip characteristics (such as quantity, shape, and humidity) and processing conditions in different work areas, improving the efficiency and accuracy of chip transfer. The inlet of the first conveyor section is connected to the machine tool's chip outlet, directly receiving freshly generated chips. The second conveyor section handles intermediate transfer, dynamically adjusting its speed based on chip accumulation to prevent blockage or overload. The outlet of the third conveyor section is connected to the chip collection chamber, ensuring stable delivery of chips. By flexibly adjusting the speed and direction of each conveyor section, the system can quickly adapt to varying processing conditions and fluctuating chip loads. Whether in emergency situations with large amounts of chip waste or routine conditions with smaller amounts of chip waste, it ensures continuous and stable transfer, enhancing the system's adaptability to complex production environments. Furthermore, the control unit intelligently allocates drive energy based on the actual load of each conveyor section, avoiding unnecessary energy waste. The controller independently controls the speed and direction of each conveyor section, providing operators with greater flexibility. In certain situations, it may be necessary to change the waste conveyor path or adjust the conveyor speed. This can be achieved through simple parameter adjustments without the need for major equipment modifications, improving operational convenience and responsiveness.

[0065] Specifically, the first conveying section, the second conveying section and the third conveying section are all strip conveyor belts.

[0066] Specifically, the ratio of the length of the first conveyor section in the predetermined direction to the overall length of the conveyor section in the predetermined direction is greater than or equal to 0.25 and less than or equal to 0.35. This ensures that waste chips generated by the machine tool are quickly and effectively captured and transferred to the subsequent conveyor section. The optimal length ratio of the first conveyor section ensures efficient initial waste collection while avoiding the energy waste and increased equipment complexity caused by an excessively long section, providing a good starting point for subsequent waste chip processing.

[0067] Specifically, the ratio of the length of the second conveying section in the predetermined direction to the overall length of the conveying section in the predetermined direction is greater than or equal to 0.45 and less than or equal to 0.55. Thus, the second conveying section is responsible for the intermediate transport of waste chips from the collection point to the storage point, and its length accounts for the majority of the entire conveying section. This enables the device to transport waste chips stably and continuously, maintaining good transport capacity and efficiency even with large amounts of waste and long transport distances. This reduces the time waste chips remain in the transport process and reduces the risk of blockage.

[0068] Specifically, the ratio of the length of the third conveying section in the preset direction to the overall length of the conveying section in the preset direction is greater than or equal to 0.15 and less than or equal to 0.25. Thus, the third conveying section, serving as the terminal of the conveying process, is responsible for accurately delivering waste chips into the chip collection chamber. Its shorter length ratio enables rapid response to control commands, ensuring efficient and accurate waste discharge, reducing waste accumulation at the end and avoiding system failures caused by poor discharge.

[0069] Specifically, L1:L2:L3 = 3:5:2. This ensures that each conveying segment works in harmony, forming an efficient and smooth waste processing chain. It not only optimizes the waste transmission path but also rationally allocates the length and function of each segment according to the different stages of waste processing, improving the overall performance and stability of the system.

[0070] Specifically, the first conveyor section is driven by a variable frequency motor and, in conjunction with an encoder, rapidly receives the initial drop. The second conveyor section, driven by a servo motor, serves as the main conveying area, with dynamic speed regulation. The third conveyor section, driven by a reduction motor, smoothly delivers waste chips to the chip collection box. If a section fails, the adjacent section automatically increases speed to compensate for the conveying capacity.

[0071] Specifically, when the weight detection component detects that concentrated material falling occurs in the first conveying section (ie, when the weight of waste chips on the first conveying section suddenly increases), the first conveying section is accelerated.

[0072] Specifically, when the chip collection device begins operation, each conveying segment must be initially moved at an initial speed, and then the speed of each conveying segment is adjusted accordingly based on the detection results of the relevant detection components. The third conveying segment always maintains its initial speed to ensure that the waste chips are smoothly loaded into the box.

[0073] In one embodiment, at least a portion of the conveyor section comprises a conveyor belt. The conveyor section also includes a torque sensor, whose detection end is located on the conveyor section and is used to detect the tension in the conveyor belt. The torque sensor is connected to a control unit, which controls the speed and direction of the conveyor belt based on the torque sensor's detection results. This configuration allows for real-time monitoring of belt tension changes during operation, ensuring continuous and stable waste conveyance. This monitoring helps prevent belt tension from becoming too tight or too loose, leading to reduced efficiency or failure, thereby improving the operational reliability of the equipment. The torque sensor is connected to the control unit, allowing it to intelligently adjust the speed and direction of the conveyor belt based on the detected tension. When the tension is excessive and approaches a set threshold, the control unit reduces the speed of the conveyor belt to prevent damage due to overload. Conversely, when the tension is low, indicating a potential conveying failure, the control unit stops the conveyor belt, thereby improving waste conveyance efficiency. This dynamic adjustment mechanism optimizes the waste handling process and reduces energy waste. By continuously monitoring the tension of the conveyor belt and taking corresponding control measures, the conveyor belt can be prevented from accelerated wear or structural deformation due to long-term high-tension or low-tension operation, thereby extending the service life of the conveyor belt and reducing equipment maintenance costs and downtime.

[0074] Specifically, the conveying section includes a first conveying section, a second conveying section, and a third conveying section, which are connected in sequence. There are three torque sensors, one for each of the first conveying section, the other for the second conveying section, and the other for the third conveying section. In this way, when the loads on the various conveying sections are uneven, the tension in each section can be detected by the corresponding torque sensors, thereby automatically balancing the speed differences between the various conveying sections. When the torque sensor detects abnormal tension in a particular conveying section, the control unit automatically adjusts the moving speed and direction of the conveying section based on the detection results to reduce its load. At the same time, the control unit also adjusts the speeds of the front and rear conveying sections accordingly to maintain flow balance across the entire conveying section and avoid overload. For example, if the first conveying section detects a sudden increase in tension, the control unit will reduce the speed of the first conveying section and appropriately increase the speed of the second conveying section, thereby reducing the pressure on the first conveying section while ensuring smooth transmission of waste chips.

[0075] In one embodiment, at least a portion of the conveying portion comprises a conveyor belt. The conveying portion further comprises a scraper structure disposed beneath the conveyor belt. The scraper structure comprises a scraping end configured to contact a supporting surface, with the scraping end being adjustable to contact or avoid the supporting surface. With this structural arrangement, the scraper structure is disposed beneath the conveyor belt, with its scraping end in contact with the supporting surface, effectively scraping away debris adhering to the conveyor belt surface. This prevents debris from accumulating during conveyance, improves the efficiency of debris transport, ensures the cleanliness and speed of the conveyor belt, and thereby enhances the performance of the entire debris collection device.

[0076] Specifically, the chip collection device also includes a visual detection component, the detection end of the visual detection component is arranged below the conveyor belt and is used to detect the residual waste chips on the bearing surface. The visual detection component and the scraper structure are both connected to the control component, and the control component is used to control the scraper structure to contact or avoid the bearing surface according to the detection results of the visual detection component. With such a structural setting, the detection end of the visual detection component is arranged below the conveyor belt, and it can identify the residual waste chips on the bearing surface of the conveyor belt in real time through high-precision image acquisition and analysis, including the particle size, distribution density and adhesion of the waste chips, providing accurate data support for waste chip cleaning. The visual detection component can be an industrial camera with high resolution and processing speed, which can meet the needs of high-speed dynamic detection. The control component receives feedback from the visual detection component and intelligently selects whether the scraping end of the scraper structure contacts the bearing surface, as well as the strength and position of the contact according to the residual waste chips on the bearing surface. For example, in areas where debris is concentrated, the control component will adjust the scraping end of the scraper structure to be close to the load-bearing surface to more effectively clean the debris; and in locations where there is less or no debris, the control component will move the scraping end of the scraper structure away from the load-bearing surface to avoid unnecessary contact and wear.

[0077] In one embodiment, the chip collection device further includes a first height detection member, which is disposed above the conveying portion and is used to detect the maximum height and minimum height of the waste chips on the conveying portion; the first height detection member is connected to a control member, which is used to control the movement speed and movement direction of at least a portion of the conveying portion based on the detection result of the first height detection member. With such a structural arrangement, the first height detection member is disposed above the conveying portion and can accurately detect the maximum height and minimum height of the waste chips on the conveyor belt, thereby being able to determine the accumulation of waste chips on the conveyor belt and whether there is an accumulation slope based on the maximum height and minimum height. The control member can then be used to adjust the movement speed and movement direction of the conveyor belt to adjust the accumulation of waste chips on the conveyor belt, so that the surface of the waste chips is smooth and not too loose or too dense.

[0078] Specifically, the first height detector is a laser displacement sensor, mounted on top of the chip collection device. It emits a laser downward toward the waste chips on the conveyor unit, scanning the surface contour of the waste chips and measuring the height and volume of the waste accumulation. When an inclined surface is detected (i.e., the difference between the maximum and minimum heights of the waste chips on the conveyor unit is greater than a preset height difference), the laser displacement sensor's detection results are used to assist in correcting the speed of at least part of the conveyor unit, which is adjusted based on the load cell's detection results.

[0079] Specifically, when the weight of the waste chips approaches a set threshold but the accumulation is loose, the conveyor belt speed is increased by 20% to facilitate the flow of the waste chips. When the weight of the waste chips does not reach the set threshold but the accumulation is dense, the conveyor belt speed is increased by 15% to prevent blockage. When different sensor data conflict, the load cell data takes precedence, and the load cell detection result directly affects the conveyor belt movement speed.

[0080] Specifically, when the laser displacement sensor detects a sloped accumulation of waste chips on the second conveyor section, the control unit briefly reverses the second conveyor section. This impact of the short reverse movement adjusts the flatness of the waste chip pile. This optimized flatness reduces chip jamming and accumulation on the second conveyor section, improves chip flowability and conveying efficiency, ensures continuous and stable chip transport, avoids blockages and overflows, and enhances the overall efficiency of the chip collection system.

[0081] Specifically, the conveyor belt's kinetic energy is provided by an electric motor, whose operating speed is adjustable to suit varying processing conditions. A control unit automatically adjusts the motor's drive speed based on data from a load cell (equivalent to a weight detector) and a laser displacement sensor (equivalent to a first height detector), thereby adjusting the conveyor belt's speed and ensuring continuous and stable waste conveying.

[0082] In one embodiment, the first height detection member includes a detection portion and a cleaning portion, the detection portion is used to detect the maximum height and minimum height of the waste chips on the conveying portion, and the cleaning portion is movably arranged on one side of the detection portion and is used to clean the detection portion; the chip collection device also includes a second height detection member, the second height detection member is arranged on one side of the conveying portion and is spaced apart from the conveying portion, and the second height detection member is used to detect the maximum height and minimum height of the waste chips on the conveying portion; the second height detection member, the cleaning portion and the detection member are all connected to a control member, and the control member is used to control the cleaning portion to clean the detection member according to the difference between the detection results of the first height detection member and the second height detection member. With such a structural arrangement, the first height detection member and the second height detection member independently monitor the height of the waste chips on the conveying portion, and the two detection members cooperate with each other to provide redundancy and verification for the waste chip height data, thereby improving the comprehensiveness and accuracy of monitoring. The cleaning part can be movably arranged on one side of the detection part. When the control part detects that there is a significant difference between the detection results of the first height detection part and the second height detection part, it is determined that the detection part may be affected by waste debris blocking or adhesion, and the cleaning part is controlled to start automatically to clean the detection part, thereby avoiding data errors and ensuring the accuracy of the monitoring data.

[0083] Specifically, the second height detection component is an ultrasonic liquid level sensor, which is used to monitor the height of waste chips and is particularly suitable for powdered waste chips.

[0084] Specifically, when the ratio of the difference between the detection results of the first height detection part and the second height detection part to the detection result of the first height detection part is greater than the preset difference ratio, it means that the detection result of the first height detection part is not accurate enough. Therefore, the cleaning part cleans the detection part to clean the contamination on the surface of the detection part.

[0085] Specifically, the preset difference ratio is 15%.

[0086] Specifically, during use, the chip collection device first detects the weight of the waste chips using a weighing sensor. When the weight reaches a preset threshold, the conveyor speed is adjusted, increasing the speed to facilitate rapid removal of the waste chips. Simultaneously, the dust collection unit increases its frequency to increase air volume. On this basis, a laser displacement sensor assists in adjusting the movement of the conveyor. Specifically, the laser displacement sensor detects the height and volume of the waste chips. When the weight approaches a preset threshold and a slope of waste chip accumulation is detected, the conveyor is briefly reversed to level the waste chips. This facilitates determining the stacking density of the waste chips based on their weight and volume. This allows for further adjustment of the conveyor speed based on the stacking density of the waste chips, based on the speed of the conveyor adjusted by the weighing sensor. Simultaneously, a second height detection element ensures the reliability of the detection results of the first height detection element. The weighing sensor primarily determines when to adjust the speed and the base speed level, while the laser displacement sensor dynamically compensates for the speed according to different waste chip accumulation patterns.

[0087] Specifically, the conveying part moves according to the initial speed before speed adjustment. The weighing sensor detects the mass of waste chips, and the maximum adjustable speed ratio is ±30% (that is, the maximum speed reduction ratio is 30%, and the maximum speed increase ratio is 30%); the maximum adjustable speed ratio of the laser displacement sensor is ±15% (that is, the maximum speed reduction ratio is 15%, and the maximum speed increase ratio is 15%); the maximum adjustable speed ratio of the dust sensor is ±5% (that is, the maximum speed reduction ratio is 5%, and the maximum speed increase ratio is 5%).

[0088] In one embodiment, the chip collection device further includes a dust detection element, which is arranged at the dust suction port of the dust collection element and is used to detect the dust concentration at the dust suction port; the dust detection element is connected to a control element, and the control element is used to adjust the air volume of the dust collection element and / or the moving speed of at least part of the conveying part according to the detection result of the dust detection element. With such a structural arrangement, when the dust detection element detects that the dust concentration exceeds a preset threshold, the control element can immediately adjust the air volume of the dust collection element, increase the suction force to more effectively capture and control the dust, avoid dust overflow, reduce pollution to the working environment, and protect the health of the operator. The control element can also intelligently adjust the moving speed of at least part of the conveying part according to the detection result of the dust detection element. When the dust concentration is high, the conveying speed is appropriately reduced to reduce the generation and flying of dust, thereby achieving more efficient dust control. At the same time, when the dust concentration is low, the conveying speed is accelerated to improve the overall waste chip processing efficiency.

[0089] Specifically, the dust detection element is a dust concentration sensor that is used to detect dust concentration. When the dust concentration suddenly increases, the dust collection power of the dust collection element is automatically increased and the conveyor belt is triggered to slow down to prevent dust.

[0090] Specifically, when the dust concentration increases suddenly (ie, the difference between the dust concentration at a later moment and the dust concentration at a previous moment is greater than a preset dust concentration difference), the conveyor belt is decelerated by 10% to reduce dust.

[0091] Specifically, the weighing sensor takes the lead in deciding when to adjust the speed and the basic speed level, and is assisted by the dust concentration sensor. The dust concentration sensor only sets a safety limit on the speed when the dust concentration is abnormal (i.e., the dust concentration increases suddenly).

[0092] In one embodiment, the dust collection unit includes a main body having interconnected air ducts and a fan chamber; the dust collection unit also includes a fan disposed within the fan chamber; the fan is connected to a control unit, which is used to control the fan's operating power to adjust the air volume of the dust collection unit. With this structural arrangement, the fan's operating power is intelligently controlled by the control unit, allowing the air volume to be flexibly adjusted according to actual operating conditions, ensuring effective dust collection while avoiding resource waste. By dynamically adjusting the fan's power, the dust collection unit can adapt to the dust collection needs of different waste volumes and materials, improving the versatility and flexibility of the device.

[0093] In one embodiment, the dust collection member includes a main body having an interconnected air duct and a fan chamber; the dust collection member also includes a filter portion and a pressure differential detection member, the filter portion being disposed within the air duct; a first detection end of the pressure differential detection member being disposed on the air inlet side of the filter portion, and a second detection end of the pressure differential detection member being disposed on the air outlet side of the filter portion, the pressure differential detection member being configured to detect a pressure differential between the air inlet and air outlet sides; the pressure differential detection member being connected to a control member, the control member being configured to control the air volume of the dust collection member based on the detection result of the pressure differential detection member. With this structural arrangement, the real-time monitoring data of the pressure differential detection member enables the control member to intelligently adjust the air volume based on the blockage of the filter portion, thereby maintaining optimal dust collection performance and ensuring that the dust collection performance remains at a consistently high level.

[0094] Specifically, changes in the pressure difference data reflect the working status of the filter unit. When the pressure difference exceeds the set threshold, the control component can also trigger an alarm, prompting maintenance personnel to clean or replace the filter unit in time, avoiding dust collection failure caused by decreased filtration efficiency and reducing unplanned downtime.

[0095] Specifically, the filter unit adopts a multi-stage filtration system, including a primary filter, a medium-efficiency filter and a high-efficiency filter. The multi-stage filters capture dust particles of different particle sizes respectively, thereby better extending the service life of the filter unit.

[0096] Specifically, a pulse back-flushing structure is provided on the filter part to achieve the purpose of automatic dust cleaning, and the dust accumulated on the filter part is automatically cleaned regularly to ensure the dust collection efficiency.

[0097] Specifically, the fan adopts variable frequency control to automatically adjust the air volume according to the processing status of the machine tool and the amount of waste chips, thereby reducing energy consumption.

[0098] Specifically, the air volume of the dust collector is first detected by a weight detector to determine the speed of waste generation. The weight detector's detection result then determines the base wind speed. A dust concentration sensor detects the coarseness of the debris, and the control unit assists in fine-tuning the air volume based on the dust concentration sensor's detection result.

[0099] Specifically, when metal cutting begins, the air volume gradually increases (such as from a breeze to a strong wind), so that flying debris can be captured immediately; when a large amount of fine dust is generated (that is, the dust concentration reaches a certain set concentration value), the dust collection component automatically increases the wind pressure to prevent dust from escaping; when the filter is half-blocked (that is, the pressure difference between the air inlet and air outlet sides of the filter reaches a certain set value), the fan increases the speed to maintain suction, and at the same time flashes an alarm; when the machine tool changes tools or pauses processing, the dust collection component automatically switches to energy-saving mode to reduce energy consumption. When the conveyor belt accelerates, the fan increases the wind force 0.5 seconds in advance to form a negative pressure preparatory state. The dust collection component also has an air outlet for exhaust. When the conveyor belt vibrates, the air outlet synchronously emits a short strong wind pulse to shake off the debris adhering to the conveyor belt. When the machine tool is shut down in an emergency, the dust collection component delays closing to clean up the waste chips in the pipeline.

[0100] In one embodiment, the chip collection device further includes a chip collection box, which is disposed at the outlet of the conveying portion and has a chip collection chamber for accommodating waste chips. The chip collection device further includes an overflow sensor, which is disposed at the top of the chip collection box and within the chip collection chamber. The overflow sensor is configured to detect the minimum distance between the waste chips in the chip collection chamber and the top of the chip collection box. The overflow sensor is connected to the control unit. With this structural arrangement, the overflow sensor monitors the accumulation of waste chips in the chip collection chamber in real time. When the waste chips approach the top of the box, an alarm mechanism is immediately activated, thereby preventing waste chips from overflowing, maintaining a clean working environment, and reducing safety hazards.

[0101] In one embodiment, the chip collection device further includes an alarm, located on one side of the chip collection box and configured to emit an alarm signal. The alarm is connected to a control unit, which controls the alarm to emit an alarm signal based on the detection results of the overflow prevention sensor. With this structural arrangement, the alarm's immediate response can promptly notify operators when waste chips approach or reach an overflow threshold, allowing them to take appropriate measures and avoid potential equipment failures and safety incidents.

[0102] In one embodiment, a discharge outlet is provided at the bottom of the chip box, and the discharge outlet can be opened and closed. The discharge outlet is connected to a control component, and the control component is used to control the opening and closing of the discharge outlet according to the detection results of the anti-overflow sensor. With such a structural arrangement, the control component automatically controls the opening and closing of the discharge outlet based on the data of the anti-overflow sensor, thereby realizing the automatic discharge of waste chips without the need for human intervention, thereby improving the automation level of the equipment. The automatic opening and closing of the discharge outlet reduces the manual operation of maintenance personnel, reduces the difficulty of maintenance, and also reduces the chance of contact with waste chips, thereby improving the working conditions of maintenance personnel. This automatic chip removal mechanism can reasonably arrange the discharge time of waste chips according to the filling status of the chip box, avoids chip removal too early or too late, optimizes resource utilization, and reduces additional energy consumption and production interruptions caused by improper chip removal.

[0103] In one embodiment, the chip collection device further includes an alarm, which is disposed on one side of the chip collection box and is configured to emit an alarm signal. The alarm is connected to a control unit, which is configured to control the alarm to emit an alarm signal based on the detection result of the overflow prevention sensor. A discharge outlet is disposed at the bottom of the chip collection box, which is openable and closable. The discharge outlet is connected to a control unit, which is configured to control the opening and closing of the discharge outlet based on the detection result of the overflow prevention sensor. With this structural arrangement, the discharge outlet is linked to the overflow prevention sensor and the control unit, forming a complete closed-loop system, ensuring the coordination of the waste chip processing process and the stability of its operation, thereby reducing the failure rate of the equipment.

[0104] Specifically, the chip box is made of corrosion-resistant materials. This material resists common industrial corrosives such as metal chips, coolant, and oil, ensuring long-term stable operation and extending the life of the equipment. Compared to conventional materials, chip boxes made of corrosion-resistant materials require less frequent maintenance and replacement, reducing maintenance costs and minimizing production interruptions caused by maintenance downtime.

[0105] Specifically, the chip box is made of corrosion-resistant materials such as stainless steel, polytetrafluoroethylene, polyvinyl chloride, and polypropylene.

[0106] Specifically, the chip box is connected to the conveying part through a conveying structure. The conveying structure can be a conveyor belt or a pipeline.

[0107] Specifically, the capacity of the chip box can be designed according to the processing requirements of the machine tool, so that chip boxes of different capacities can be quickly replaced according to the processing requirements of different machine tools, thereby improving the versatility of the device.

[0108] Specifically, a transparent window is provided on the outer wall of the chip box so as to observe the filling status inside the chip box.

[0109] Specifically, a detachable cover is provided on the top of the chip collection box to facilitate regular cleaning of metal chips.

[0110] Specifically, a liquid level sensor (such as an ultrasonic sensor) and a weighing sensor are installed inside the chip box to monitor the height and weight of the waste chips in real time, providing more accurate information on the waste chip capacity. An automatic chip discharge port (equivalent to the discharge port mentioned above) is designed at the bottom of the chip box. When the waste chips reach the set capacity, the automatic chip discharge port automatically opens and the waste chips are discharged to a centralized processing area via a conveyor belt or pipe, reducing manual intervention.

[0111] like Figure 1 As shown, Figure 1The automated workflow of the chip collection system is shown. After the chip collection system begins collecting chips, sensors begin monitoring. A load cell measures the weight of the chips, ensuring real-time monitoring of the accumulated amount. A laser displacement sensor detects the height of the chips, enabling timely action. An ultrasonic sensor monitors the height of the chips and compares it with the laser displacement sensor to ensure accurate detection results. A dust sensor (also known as a dust concentration sensor) monitors air quality and dust concentration. Once the chip level reaches the cleaning threshold (the load cell measurement reaches a preset threshold), the process automatically transitions to the cleaning process. This involves adjusting the conveyor speed based on the chip level, adjusting the dust collection air volume based on the dust level, and automatically removing chips from the chip box. This process, aided by a conveyor belt or duct, ensures efficient chip removal. While these devices are being adjusted, the chip collection system monitors system status. During this phase, the PLC control system (control unit) monitors the status of the chip collection system in real time, displaying key data such as chip weight, chip height, and conveyor speed through the human-machine interface, allowing operators to monitor equipment operation in real time. During the monitoring phase, if a device fault is detected, the system automatically initiates a troubleshooting process. This process begins with an automatic alarm and display of fault information. Operators then follow the prompts to perform repairs, ensuring the device is restored to normal operation, thereby reducing downtime and improving equipment efficiency.

[0112] Specifically, the real-time monitoring status of the PLC control system includes: 1. Core operating status, such as: conveyor belt, motor current, speed, synchronization deviation of each conveying section, and the operating frequency, vibration amplitude, bearing temperature of the fan of the dust collection part, as well as the opening and closing position signal and action count of the chip discharge door (equivalent to the discharge outlet of the chip collection box); 2. Safety protection status, such as: hardware protection to prevent motor overload, mechanical limit moving parts, etc.; 3. Environmental safety, such as: dust accumulation, automatic start of cooling fan when the temperature inside the electric control cabinet reaches a certain level, etc.; 4. Energy efficiency management monitoring, such as: waste chip processing speed, etc.; 5. Maintenance inspection, such as: conveyor belt wear, filter life, lubrication reminder, consumables status, etc.

[0113] Specifically, equipment failures include: 1. Mechanical aspects: waste chips blocking the conveyor belt, scraper wear and falling off, conveyor belt deviation, etc.; 2. Electrical aspects: sensor failure, circuit aging, poor contact, etc.; 3. Pneumatic / hydraulic methods: insufficient dust suction force, chip removal door cannot be opened, etc.; 4. Control system aspects: PLC crashes, conveyor belt suddenly reverses, etc.

[0114] like Figure 2As shown, one embodiment of the present invention provides a control method, which is applicable to the above-mentioned chip collection device, and the control method includes: obtaining the weight of waste chips on the conveying part of the chip collection device to obtain the actual weight; comparing the actual weight with a preset threshold, and adjusting the moving speed of at least part of the conveying part and the air volume of the dust collection part of the chip collection device according to the difference between the actual weight and the preset threshold.

[0115] By using the control method provided by one embodiment of the present invention, the actual weight of the waste chips on the conveying part can be compared with a preset threshold value, and the moving speed of the conveying part and the air volume of the dust collecting part can be intelligently adjusted according to the difference between the two. In this way, when the amount of waste chips is small, the conveying speed and the dust collecting air volume can be reduced to save energy; and when the waste chips approach or reach the cleaning threshold, the conveying speed is accelerated and the dust collecting air volume is increased to ensure timely and effective processing of the waste chips. By precisely controlling the speed of the conveying part and the air volume of the dust collecting part, unnecessary overloads are avoided, equipment wear is reduced, thereby extending the service life of the entire chip collection device and reducing maintenance costs and equipment depreciation costs. Moreover, based on the monitoring and adjustment of the actual weight, the status of the waste chips can be remotely monitored, abnormal conditions can be discovered in time, and potential faults can be warned, so that measures can be taken in advance to avoid production interruptions, thereby enhancing the reliability of the equipment and the stability of the production plan. Therefore, the control method provided by this embodiment can solve the problem of low automation level of the chip collection device in the prior art.

[0116] Specifically, the preset threshold is set according to the material density of the waste, and different preset thresholds are used for waste of different materials. For example, when the waste is aluminum, the preset threshold is 80 kg.

[0117] Specifically, when the actual weight is greater than or equal to a preset threshold, the chip collection device will trigger an alarm state.

[0118] Specifically, the conveying portion includes a support structure and a conveying member, wherein the conveying member is movably arranged on the support structure and forms at least a part of the conveying portion. The conveying member is a conveyor belt.

[0119] Specifically, the air volume of the dust collecting member is adjusted by adjusting the power of a fan provided in the dust collecting member.

[0120] In one embodiment, a method for adjusting the speed of at least a portion of a conveying unit based on the difference between an actual weight and a preset threshold value includes: increasing the speed of at least a portion of the conveying unit when the actual weight is greater than or equal to the preset threshold value; and maintaining the speed of at least a portion of the conveying unit unchanged when the actual weight is less than the preset threshold value. A method for adjusting the air volume of a dust collection unit of a chip collection device based on the difference between the actual weight and the preset threshold value includes: increasing the air volume of the dust collection unit when the actual weight is greater than or equal to the preset threshold value; and maintaining the air volume of the dust collection unit unchanged when the actual weight is less than the preset threshold value. With this arrangement, when the actual weight approaches or reaches the preset threshold value, the system automatically increases the speed of the conveying unit, accelerating the delivery of waste chips to the chip collection box, reducing the retention time of waste chips, avoiding the degradation of machine tool performance due to waste chip accumulation, and improving the timeliness and efficiency of waste chip processing. When the waste chip volume is low, the system maintains the original operating state of the conveying unit and the dust collection unit, avoiding unnecessary energy consumption, achieving energy-saving and environmentally friendly equipment operation, and reducing production costs. The suction air volume is dynamically adjusted based on actual weight. When the amount of waste chips is high, the air volume is increased to ensure efficient dust collection and prevent metal chips from flying in the air, which could pose a safety hazard and environmental pollution. When the amount of waste chips is low, the air volume is maintained at a lower level, reducing energy waste, lowering the burden on the dust collection system, and extending the equipment's lifespan. Through refined speed and air volume control, excessive load on the equipment during waste processing is avoided, reducing wear on the conveyor belt and dust collection components, and reducing the frequency of maintenance and component replacement, thereby saving maintenance costs and extending the overall equipment lifespan.

[0121] In one embodiment, after comparing the actual weight with a preset threshold, the control method further comprises: when the difference between the actual weight and the preset threshold is less than the preset weight difference, obtaining the maximum height and minimum height of the waste on the conveying portion and comparing the maximum height and the minimum height; when the difference between the maximum height and the minimum height is greater than the preset height difference, causing at least a portion of the conveying portion to move in the reverse direction at least once, and each reverse movement lasting for a preset time period before the at least portion of the conveying portion is moved forward again; when the difference between the maximum height and the minimum height is less than or equal to the preset height difference, maintaining the direction of movement of at least a portion of the conveying portion unchanged; when the difference between the actual weight and the preset threshold is greater than or equal to the preset weight difference, maintaining the direction of movement of at least a portion of the conveying portion unchanged. With such a configuration, when the difference between the actual weight and the preset threshold is small, and the difference between the maximum height and the minimum height of the waste exceeds the preset height difference, i.e., when the waste accumulation slope is severe, the conveyor belt will be able to reverse for a preset time period to cause the waste surface to be re-leveled. In this way, the waste can be more evenly distributed on the conveying portion, avoiding a situation where there is too much waste on one side and the other side is empty. Balanced chip distribution and timely reverse movement strategies can effectively prevent chip overflow or blockage of the conveying section, reducing safety risks and ensuring operator safety and normal equipment operation.

[0122] It should be noted that the forward direction refers to the direction from the chip outlet to the chip collecting box, and the reverse direction refers to the direction from the chip collecting box to the chip outlet.

[0123] Specifically, the preset time length is less than or equal to 2 seconds. In this way, the short preset time length can cause the conveyor belt to run in the reverse direction for a short period of time. The rapid change in conveying direction causes the waste chips on the conveyor belt to shake, thereby leveling the accumulated waste chips and adjusting the waste chip distribution in real time, avoiding uneven accumulation of waste chips for a long time and improving the immediacy and efficiency of waste chip processing.

[0124] Specifically, the case where the difference between the maximum height and the minimum height is greater than the preset height difference corresponds to a case where the waste chips on the conveying portion are accumulated on an inclined surface.

[0125] In one embodiment, after comparing the actual weight with the preset threshold, the control method further includes: obtaining the volume of the waste chips on the conveying part, and obtaining the stacking density of the waste chips on the conveying part based on the actual weight and volume; when the difference between the actual weight and the preset threshold is less than the preset weight difference, when the stacking density is less than the preset stacking density, the moving speed of at least part of the conveying part is increased according to a first speed-up ratio; when the stacking density is greater than or equal to the preset stacking density, the moving speed of at least part of the conveying part is increased according to a second speed-up ratio; when the difference between the actual weight and the preset threshold is greater than or equal to the preset weight difference, when the stacking density is less than the preset stacking density, the moving speed of at least part of the conveying part is increased according to a third speed-up ratio; when the stacking density is greater than or equal to the preset stacking density, the moving speed of at least part of the conveying part is increased according to a fourth speed-up ratio; wherein the first speed-up ratio is greater than the second speed-up ratio; the third speed-up ratio is greater than the fourth speed-up ratio; the first speed-up ratio is greater than the third speed-up ratio; and the second speed-up ratio is greater than the fourth speed-up ratio. By calculating the stacking density of the waste chips, the equipment can adjust the conveyor speed based on the physical characteristics of the waste chips. When the stacking density is low, a higher speed increase ratio is used to speed up the conveying of the waste chips, thereby compensating for the space utilization issues caused by loose distribution of the waste chips. When the stacking density is high, a lower speed increase ratio is used to avoid overload or blockage caused by dense waste chips. By adjusting the movement speed, the equipment can intelligently control the distribution of waste chips in the chip collection device, avoiding the space wasted due to uneven accumulation or unstable density of waste chips, and improving the efficiency of waste collection.

[0126] In one embodiment, the chip collection device is the above-mentioned chip collection device, and the conveying portion is a conveyor belt structure; wherein, the method for adjusting the moving speed of at least part of the conveying portion according to the difference between the actual weight and the preset threshold value includes: adjusting the moving speed of the first conveying section and the second conveying section of the chip collection device according to the difference between the actual weight and the preset threshold value, so that the moving speed of the third conveying section of the chip collection device remains unchanged. With such a setting, by adjusting the speed of the first conveying section and the second conveying section, the equipment can dynamically accelerate or decelerate according to the actual weight of the waste chips, ensuring that the waste chips can be transported to the chip collection box in a timely and effective manner, thereby improving the efficiency and accuracy of waste chip processing. The constant moving speed of the third conveying section can avoid the influence of the change in speed on the smooth entry of the waste chips into the chip collection box, thereby reducing dust and the overflow of waste chips, and ensuring that the waste chips are stably collected by the chip collection box.

[0127] In one embodiment, the chip collection device is the chip collection device described above, and the conveying portion is a conveyor belt structure; wherein the control method further comprises: obtaining the tension of the second conveying section of the chip collection device; when the tension is greater than a preset tension, decelerating the first conveying section of the chip collection device and causing the third conveying section of the chip collection device to run in reverse; when the tension is less than or equal to the preset tension, maintaining the moving speed and direction of the first conveying section, the second conveying section, and the third conveying section. With such a setting, by monitoring the tension of the conveying section, the speed and direction of the conveyor belt are adjusted in a timely manner, thereby avoiding potential mechanical failures and operational risks and improving workplace safety. When the tension of the second conveying section is too large, by decelerating the first conveying section and causing the third conveying section to run in reverse, the conveying pressure of the second conveying section is effectively alleviated, thereby avoiding equipment damage or failure and ensuring the normal operation of the equipment.

[0128] Specifically, when the tension is greater than the preset tension, the first conveying section is immediately decelerated by 50%, the third conveying section is briefly reversed to release the pressure, and the chip collection device emits an alarm sound and light to indicate the risk of blockage.

[0129] In one embodiment, the chip collection device is used to collect and discharge waste chips generated by the cutting device; the control method also includes: obtaining the working state of the cutting device; when the cutting device switches from a stopped state to a cutting state, increasing the air volume of the dust collection member; when the cutting device switches from a cutting state to a stopped state, reducing the air volume of the dust collection member. With this arrangement, when the cutting device starts working, increasing the air volume of the dust collection member can quickly capture and collect waste chips generated during the processing process, ensuring that the waste chips do not float or scatter in the air, thereby improving the efficiency and effectiveness of waste chip collection. Reducing the air volume of the dust collection member when the cutting device is in a stopped state avoids high energy consumption when the equipment is operating when no waste chips are generated, achieving energy-saving operation, reducing production costs, and meeting the requirements of green production. By dynamically adjusting the air volume of the dust collection member, the continuity and coordination of the production process are ensured, production interruptions caused by improper waste chip handling are avoided, and production efficiency and the smoothness of the overall workflow are improved.

[0130] Specifically, the cutting device is a machine tool. The working states of the cutting device include a stop state and a cutting state. When the cutting device is in the stop state, the cutting device does not generate waste chips; when the cutting device is in the cutting state, the cutting device generates waste chips.

[0131] In one embodiment, the control method further comprises: continuously obtaining the moving speed of at least a portion of the conveying unit; increasing the air volume of the dust collecting element when the moving speed of at least a portion of the conveying unit increases; decreasing the air volume of the dust collecting element when the moving speed of at least a portion of the conveying unit decreases; and maintaining the air volume of the dust collecting element constant when the moving speed of at least a portion of the conveying unit remains unchanged. With this arrangement, the air volume of the dust collecting element increases as the speed of the conveying unit increases, ensuring that waste chips can still be effectively captured even when they are moving rapidly, preventing waste chips from diffusing in the air or reattaching to the machine tool surface, and improving the overall efficiency of waste chip collection. As the speed of the conveying unit changes, the air volume of the dust collecting element adjusts accordingly, achieving a precise match between the two, avoiding the use of excessively high air volumes when the waste chip transmission rate is low, reducing unnecessary energy consumption, and achieving energy conservation and environmental protection. By synchronously adjusting the air volume and moving speed, the various components of the equipment operate more coordinated, reducing equipment wear and failure caused by improper waste chip handling or overload operation, and effectively extending the service life of the entire chip collection device.

[0132] One embodiment of the present invention provides a control device applicable to the above-mentioned control method, comprising an acquisition unit, a comparison unit, and a control unit. The acquisition unit is used to acquire the weight of waste chips on the conveying portion of the chip collection device to obtain an actual weight; the comparison unit is connected to the acquisition unit and is used to compare the actual weight with a preset threshold; and the control unit is connected to the comparison unit and is used to adjust the moving speed of at least part of the conveying portion and the air volume of the dust collection device's dust collection member based on the difference between the actual weight and the preset threshold.

[0133] The control device provided by one embodiment of the present invention can compare the actual weight of the waste chips on the conveying part with a preset threshold value, and intelligently adjust the moving speed of the conveying part and the air volume of the dust collection part based on the difference between the two. In this way, when the amount of waste chips is small, the conveying speed and the dust collection air volume can be reduced to save energy; and when the waste chips approach or reach the cleaning threshold, the conveying speed is accelerated and the dust collection air volume is increased to ensure timely and effective processing of the waste chips. By precisely controlling the speed of the conveying part and the air volume of the dust collection part, unnecessary overloads are avoided, equipment wear is reduced, thereby extending the service life of the entire chip collection device and reducing maintenance costs and equipment depreciation costs. Moreover, based on the monitoring and adjustment of the actual weight, the status of the waste chips can be remotely monitored, abnormal conditions can be discovered in time, and potential faults can be warned, so that measures can be taken in advance to avoid production interruptions, thereby enhancing the reliability of the equipment and the stability of the production plan.
