Description

Technical Field

[0001] The present invention relates to the technical field of plate cutting equipment, and in particular to a cutting and feeding device. Background Art

[0002] In the modern woodworking industry, panel cutting is a core process across furniture manufacturing, architectural decoration, and other fields. As market demands for panel processing precision, efficiency, and large-scale production continue to rise, the degree of automation in panel cutting equipment has gradually become a key indicator of industry competitiveness. However, panel loading, especially the handling and positioning of large-sized panels, still generally relies on manual operation.

[0003] At present, when loading large-sized boards in a woodworking workshop, two or more workers are required to hold the two sides of the board respectively, lift it with the strength of their waist and arms, adjust the angle and place it on the work surface of the cutting equipment; finally, the position of the board is adjusted by manual pushing and pulling to align it with the positioning reference of the equipment. Workers need to bend and lift frequently when carrying the board, which can easily lead to occupational injuries such as lumbar muscle strain. In addition, during the manual handling process, the board may fall due to workers' coordination errors, slippery ground or hand slippage, causing equipment damage or personal injury accidents. At the same time, the sharp edges of the board can easily scratch the hands. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides a cutting and feeding device that can replace manual handling, efficiently clean dust, and ensure reliable adsorption of suction cups.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A cutting and feeding device includes a feeding member for grabbing a plate body and a moving member for moving the feeding member, wherein the feeding member is arranged on the moving member and includes a grabbing member for sucking the plate body and a dust cleaning member for removing dust from the surface of the plate body;

[0007] The dust cleaning member can sweep the dust on the surface of the plate through a composite airflow and form a negative pressure field to guide the dust before the grabbing member contacts the plate. The composite airflow includes a spiral airflow tangential to the plate surface and a central airflow perpendicular to the plate surface.

[0008] Preferably, the dust cleaning member includes a sleeve provided on the grasping member. An inclined conical channel is formed in the sleeve wall. The conical channel can eject a spiral air flow. A linear through hole capable of ejecting a vertical air flow from the central region is provided in the grasping member. The spiral air flow and the vertical air flow cooperate to form a negative pressure field. The inclined conical channel in the sleeve wall enables the air flow to be ejected in a spiral manner. This spiral air flow has a strong tangential force, which can effectively peel the dust from the surface of the plate and guide it to the edge. The linear through hole in the grasping member ejects a vertical air flow, which can lift the dust from the central region and cooperate with the spiral air flow to form a stable negative pressure field. This structural design makes the dust cleaning process more accurate and efficient, can effectively reduce dust residue, improve the cleanliness of the plate, and provide a good foundation for subsequent adsorption and processing processes.

[0009] Preferably, the loading member includes a frame and a lifting device. The lifting device is installed on the frame and connected to the grasping member. The moving member includes a bracket and a linear module. The linear module is provided on the bracket, and the frame is provided on the linear module. The lifting device can drive the grasping member to move up and down to achieve the grasping and placing of the plate. The linear module can accurately control the horizontal movement of the frame, enabling the loading member to accurately reach the plate placement area and the workbench of the plate cutting device.

[0010] Preferably, a plurality of grasping members are provided. The grasping member includes a connecting rod and a suction cup. The connecting rod is connected to the loading member. The linear through hole is provided on the connecting rod. A first connecting pipe head communicating with the linear through hole is provided on the connecting rod. The first connecting pipe head is connected to a negative pressure air source device through a pipeline. The suction cup is provided on the sleeve. The linear through hole communicates with the inner cavity of the suction cup. The linear through hole on the connecting rod is not only used to eject a vertical air flow for dust cleaning but also serves as a negative pressure channel, enabling the suction cup to generate an adsorption force.

[0011] Preferably, the frame includes a moving plate. The moving plate is connected to the linear module. Connecting plates are symmetrically provided on the moving plate. Fixing plates are provided on the two connecting plates. The lifting device is provided on the fixing plates. An installation plate is provided on the output shaft of the lifting device. The connecting rod is provided on the installation plate. The lifting device can be a cylinder or an electric cylinder and other devices when in use, used to drive the installation plate to move up and down. The distance sensor can be installed on the installation plate when set.

[0012] Preferably, the sleeve is sleeved on the connecting rod. A third connecting pipe head communicating with the conical channel is provided on the sleeve. The air outlet end of the conical channel faces the plate body. A second connecting pipe head communicating with the linear through hole is provided on one side of the connecting rod. Both the second connecting pipe head and the third connecting pipe head are connected to a blowing device through pipelines. The second connecting pipe head and the third connecting pipe head are connected to the blowing device, so as to introduce compressed air into the linear through hole and the conical channel respectively. The compressed air introduced into the conical channel forms a spiral air flow. The air outlet end of the conical channel faces the plate body, ensuring that the spiral air flow can directly act on the surface of the plate and improving the dust cleaning effect. A net plate can be provided at the end of the second connecting pipe head where the gas enters according to the actual situation to ensure that the vertical air flow is not stronger than the spiral air flow.

[0013] Preferably, the dust cleaning member further includes a cover body. A fixing block is provided on the sleeve. The cover body is movably sleeved on the sleeve. A spring is provided between the cover body and the fixing block. A fitting ring is provided on the contact surface between the lower part of the cover body and the plate body. When the cover body contacts the surface of the plate, the spring can play a buffering role to avoid damaging the plate. The setting of the fitting ring enhances the sealing performance between the cover body and the surface of the plate and prevents dust from leaking from the edge of the cover body. During the dust cleaning process, a relatively closed space is formed between the cover body and the surface of the plate, which is beneficial to the formation of a stable negative pressure field by the spiral air flow and the vertical air flow, and improves the collection and guiding effect of dust.

[0014] Preferably, a distance sensor is provided on the loading member. A pressure sensor is provided at the pipeline connection part connected to the first connecting pipe head. The distance sensor is used to control the moving distance of the lifting device. The pressure sensor is used to monitor the negative pressure value in the suction cup. A controller and an alarm are further provided on the moving member. The distance sensor can detect the position of the plate in real time and provide an accurate control signal for the movement of the lifting device to ensure that the grasping member can accurately reach the surface of the plate. The pressure sensor is used to monitor the negative pressure value in the suction cup and feedback it to the controller.

[0015] Preferably, the controller can execute the following steps: when the pressure sensor detects that the negative pressure value in the suction cup does not reach the preset adsorption threshold, control the lifting device to drive the suction cup to move up a certain distance, and at the same time send an instruction to the dust cleaning member to restart purging the surface of the plate;

[0016] After the purging is completed, the controller controls the lifting device to drive the suction cup to descend again to contact the plate body for secondary adsorption;

[0017] If the adsorption fails three times in a row, the controller triggers the alarm and controls the device to stop running;

[0018] It stipulates the processing logic of the controller when adsorption fails. When the pressure sensor detects that the negative pressure value in the suction cup does not reach the preset adsorption threshold, the controller controls the lifting device to move the suction cup up a certain distance, and then starts the dust cleaning component again for secondary purging to remove the possibly remaining dust. After the purging is completed, adsorption is attempted again. If adsorption fails three times in a row, the controller triggers the alarm component and controls the device to stop running, and at the same time stores relevant data. This retry mechanism and fault handling method improve the fault tolerance of the feeding rack, reduce adsorption failures caused by accidental factors, and ensure the continuity and stability of production.

[0019] Preferably, the controller includes a storage module for recording the negative pressure value, purging times, and plate position data each time adsorption fails. The alarm includes an audible and visual alarm installed on the device main body. When adsorption fails three times in a row, the controller controls the audible and visual alarm to emit a flashing light and a beeping alarm signal. The storage module records the negative pressure value, purging times, and plate position data each time adsorption fails, providing an important basis for equipment maintenance and fault diagnosis. The audible and visual alarm emits an obvious alarm signal when adsorption fails three times in a row, attracting the attention of the operator.

[0020] A solenoid valve one is provided on the connecting pipe head one, and solenoid valve twos are provided on both the connecting pipe head two and the connecting pipe head three. The solenoid valve one and the solenoid valve twos are all linked with the controller and can close the corresponding channels when blowing air or forming negative pressure. When the solenoid valve one, solenoid valve twos, negative pressure gas source device, blowing device, lifting device, linear module, and alarm are connected to the power supply, they are all connected to the power supply through a relay module. The controller is connected to the control module to control the on-off of the power supply.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention realizes the full-automatic grasping, transferring, and positioning of large-size plates through the linkage of the linear module and the lifting device, completely replacing manual handling, effectively improving the feeding efficiency of the plates, and eliminating the risk of lumbar muscle strain caused by bending and lifting, as well as safety hazards such as plate falling and scratching.

[0023] Moreover, the provided dust cleaning component forms a vortex negative pressure field through spiral + vertical combined airflows, can effectively remove the dust at the adsorption part of the plate, and cooperates with the elastic sealing cover to avoid dust scattering, ensuring the cleanliness of the adsorption surface of the suction cup. And the intelligent control system supports automatic retry (up to 3 times) when adsorption fails, and records data such as negative pressure value and plate position to assist in fault diagnosis, effectively improving the adsorption success rate.

[0038] Please refer to Figure 1-8 , a cutting and feeding device, including a loading member 2 for grasping a plate body and a moving member 1 for moving the position of the loading member 2. The loading member 2 is arranged on the moving member 1. The loading member 2 includes a grasping member 24 for adsorbing the plate body and a dust cleaning member 25 for removing dust on the surface of the plate body. The dust cleaning member 25 can, before the grasping member 24 contacts the plate, blow the dust on the surface of the plate through a composite air flow and form a negative pressure field for guiding the dust. The composite air flow includes a spiral air flow tangential to the surface of the plate and a central air flow perpendicular to the surface of the plate.

[0039] The dust cleaning member 25 includes a sleeve 251 arranged on the grasping member 24. An inclined conical channel 2511 is formed in the wall of the sleeve 251. The conical channel 2511 can eject a spiral air flow. A straight through hole 2424 capable of ejecting a vertical air flow from the central area is arranged in the grasping member 24. The spiral air flow and the vertical air flow cooperate to form a negative pressure field. The inclined conical channel 2511 in the wall of the sleeve 251 can make the air flow eject in a spiral manner. This spiral air flow has a strong tangential force, which can effectively peel the dust from the surface of the plate and guide it to the edge. The straight through hole 2424 in the grasping member 24 ejects a vertical air flow, which can raise the dust from the central area and cooperate with the spiral air flow to form a stable negative pressure field. This structural design makes the dust cleaning process more accurate and efficient, can effectively reduce dust residue, improve the cleanliness of the plate, and provide a good foundation for subsequent adsorption and processing processes.

[0040] The loading component 2 includes a frame 21 and a lifting device 22. The lifting device 22 is installed on the frame 21 and connected to the grasping component 24. The moving component 1 includes a bracket 11 and a linear module 12. The linear module 12 is arranged on the bracket 11, and the frame 21 is arranged on the linear module 12. The lifting device 22 can drive the grasping component 24 to move up and down to realize the grasping and placing of the board. The linear module 12 can accurately control the horizontal movement of the frame 21, enabling the loading component 2 to accurately reach the board placement area and the workbench of the panel cutting device. The linear module 12 is a mechanical device for realizing linear motion when in use.

[0041] There are multiple grasping components 24. The grasping component 24 includes a connecting rod 242 and a suction cup 241. The connecting rod 242 is connected to the loading component 2. A linear through hole 2424 is arranged on the connecting rod 242. A first connecting pipe head 2421 communicating with the linear through hole 2424 is arranged on the connecting rod 242. The first connecting pipe head 2421 is connected to a negative pressure air source device through a pipeline. The suction cup 241 is arranged on a sleeve 251. The linear through hole 2424 communicates with the inner cavity of the suction cup 241. The linear through hole 2424 on the connecting rod 242 is not only used to eject vertical air flow for dust cleaning but also serves as a negative pressure channel, enabling the suction cup 241 to generate an adsorption force.

[0042] The frame 21 includes a moving plate 211. The moving plate 211 is connected to the linear module 12. Connecting plates 212 are symmetrically arranged on the moving plate 211. A fixing plate 213 is arranged on the two connecting plates 212. The lifting device 22 is arranged on the fixing plate 213. An installation plate 23 is arranged on the output shaft of the lifting device 22. The connecting rod 242 is arranged on the installation plate 23. The lifting device 22 can be a cylinder or an electric cylinder and other devices when in use, used to drive the installation plate 23 to move up and down. The distance sensor 3 can be installed on the installation plate 23 when set.

[0043] The sleeve 251 is sleeved on the connecting rod 242. A third connecting pipe head 252 communicating with a conical channel 2511 is arranged on the sleeve 251. The air outlet end of the conical channel 2511 faces the board body. A second connecting pipe head 2422 communicating with the linear through hole 2424 is arranged on one side of the connecting rod 242. Both the second connecting pipe head 2422 and the third connecting pipe head 252 are connected to a blowing device through pipelines. The second connecting pipe head 2422 and the third connecting pipe head 252 are connected to the blowing device, thereby introducing compressed air into the linear through hole 2424 and the conical channel 2511 respectively. The compressed air introduced into the conical channel 2511 forms a spiral air flow. The air outlet end of the conical channel 2511 faces the board body, ensuring that the spiral air flow can directly act on the surface of the board to improve the dust cleaning effect. Whether to set a mesh plate for weakening the vertical air flow at the end of the second connecting pipe head 2422 for entering gas can be selected according to the actual situation to ensure that the vertical air flow is not stronger than the spiral air flow.

[0044] The dust cleaning component 25 further includes a cover body 256. A fixing block 254 is provided on the sleeve 251. The cover body 256 is movably sleeved on the sleeve 251. A spring 255 is provided between the cover body 256 and the fixing block 254. A fitting ring 2561 is provided on the contact surface between the lower part of the cover body 256 and the plate body. When the cover body 256 contacts the surface of the plate, the spring 255 can play a buffering role to avoid damaging the plate. The setting of the fitting ring 2561 enhances the sealing performance between the cover body 256 and the surface of the plate, preventing dust from leaking from the edge of the cover body 256. During the dust cleaning process, a relatively closed space is formed between the cover body 256 and the surface of the plate, which is conducive to the formation of a stable negative pressure field by the spiral air flow and the vertical air flow, improving the dust collection and guiding effects.

[0045] The feeding component 2 is provided with a distance sensor 3. A pressure sensor 4 is provided inside the pipeline connection part connected to the connecting pipe head 2421. The distance sensor 3 is used to control the moving distance of the lifting device 22. The pressure sensor 4 is used to monitor the negative pressure value inside the suction cup 241. The moving component 1 is also provided with a controller 5 and an alarm. The distance sensor 3 can detect the position of the plate in real time, providing an accurate control signal for the movement of the lifting device 22 to ensure that the grasping component 24 can accurately reach the surface of the plate. The pressure sensor 4 is used to monitor the negative pressure value inside the suction cup 241 and feedback it to the controller 5.

[0046] The controller 5 can execute the following steps: when the pressure sensor 4 detects that the negative pressure value inside the suction cup 241 does not reach the preset adsorption threshold, control the lifting device 22 to drive the suction cup 241 to move up a certain distance, and at the same time send an instruction to the dust cleaning component 25 to restart purging the surface of the plate;

[0047] After the purging is completed, the controller 5 controls the lifting device 22 to drive the suction cup 241 to descend again to contact the plate body for secondary adsorption;

[0048] If the adsorption fails three times in a row, the controller 5 triggers the alarm and controls the equipment to stop running;

[0049] The processing logic of the controller 5 in case of adsorption failure is specified. When the pressure sensor 4 detects that the negative pressure value inside the suction cup 241 does not reach the preset adsorption threshold, the controller 5 controls the lifting device 22 to move the suction cup 241 up a certain distance, and restart the dust cleaning component 25 for secondary purging to remove the possibly remaining dust. After the purging is completed, try to adsorb again. If the adsorption fails three times in a row, the controller 5 triggers the alarm component and controls the equipment to stop running, and at the same time stores the relevant data. This retry mechanism and fault handling method improve the fault tolerance of the feeding rack, reduce the adsorption failure caused by accidental factors, and ensure the continuity and stability of production.

[0050] The controller 5 includes a storage module for recording the negative pressure value, the number of purging times, and the plate position data each time the adsorption fails. The alarm includes an audible and visual alarm disposed on the device body. When the adsorption fails three times in a row, the controller 5 controls the audible and visual alarm to emit a flashing light and a beeping alarm signal. The storage module records the negative pressure value, the number of purging times, and the plate position data each time the adsorption fails, providing an important basis for the maintenance and fault diagnosis of the device. The audible and visual alarm emits an obvious alarm signal when the adsorption fails three times in a row, attracting the attention of the operator;

[0051] A first solenoid valve 2423 is provided on the first connection pipe head 2421, and second solenoid valves 253 are provided on both the second connection pipe head 2422 and the third connection pipe head 252. The first solenoid valve 2423 and the second solenoid valves 253 are all linked with the controller 5 and can close the corresponding channels when blowing air or forming negative pressure. When the first solenoid valve 2423, the second solenoid valves 253, the negative pressure gas source device, the blowing device, the lifting device 22, the linear module 12, and the alarm are connected to the power supply, they are all connected to the power supply through the relay module 6. The controller 5 is connected to the control module to control the on-off of the power supply.

[0052] When loading the board, the controller 5 starts the linear module 12 to drive the frame 21 and the loading part 2 to move to the board placement area. The distance sensor 3 can check the board position and feedback it to the controller 5. The controller 5 drives the lifting device 22 to act by controlling the relay module 6. The output shaft of the lifting device 22 extends and drives the grasping part 24 to move downward through the mounting plate 23, so that the cover 256 of the dust cleaning part 25 contacts and fits with the board surface (at this time, the spring 255 is compressed by a certain distance). At this time, there is still a certain distance between the suction cup 241 and the board. Then the controller 5 opens the relay module 6 of the blowing device by controlling the relay module 6. At this time, the first solenoid valve 2423 is in the closed state. The controller 5 controls the two second solenoid valves 253 corresponding to the second connection pipe head 2422 and the third connection pipe head 252 to open. The blowing device blows compressed air through the second connection pipe head 2422 and the third connection pipe head 252 into the conical channel 2511 and the straight through hole 2424 respectively. The air flow entering the conical channel 2511 is ejected in a spiral air flow manner, and the air flow entering the straight through hole 2424 is ejected in a vertical air flow manner. The middle vertical air flow can blow the dust, and the spiral air flow can form a negative pressure field in the center, spirally throwing the blown dust to the edge of the cover 256, so as to perform local dust treatment on the board body, and the treated dust will not fly in the air or be blown under the adjacent suction cup 241 to cause interference;

[0053] After the dust cleaning is completed, the controller 5 controls the relay module 6 to turn off the air blowing device. At the same time, the second solenoid valve 253 is also closed, and the first solenoid valve 2423 is opened. The controller 5 controls the relay module 6 to start the lifting device 22 to move downward, ensuring that the suction cup 241 contacts and fits with the plate body, and turns on the relay of the negative pressure air source device. At this time, the circuit of the negative pressure air source device is connected, and a negative pressure is established in the suction cup 241 through the linear through hole 2424 to adsorb the plate body. The pressure sensor 4 monitors the negative pressure value in the suction cup 241 in real time and transmits the data to the controller 5. If the negative pressure reaches the standard, the lifting device 22 lifts the plate to the transportation height; if it does not reach the standard, the following steps are executed:

[0054] Treatment for adsorption failure:

[0055] The controller 5 controls the relay module 6 to control the lifting device 22 to move the suction cup 241 upward by 5 - 10 mm. At the same time, the air blowing device is turned on again, the negative pressure air source device is turned off, the second solenoid valve 253 is opened, and the first solenoid valve 2423 is closed. The dust cleaning part 25 is restarted for secondary purging. After the purging is completed, the relay is controlled again to switch the air path and try to adsorb. When the adsorption fails three times in a row, the controller 5 controls the relay module 6 to power on the alarm for warning, and at the same time, the device stops. The controller 5 stores the current negative pressure value (such as -70 kPa), the number of purging times (3 times), and the position of the plate (X = 1.2 m, Y = 0.8 m) in the storage module for subsequent maintenance.

[0056] When the adsorption is successful, the linear module 12 drives the feeding part 2 to move to the workbench of the plate cutting device, and the lifting device 22 descends to place the plate to complete the feeding. During the transfer process, the controller 5 controls the relay to drive the linear module 12 and the lifting device 22 to act according to the preset program to ensure that the plate is accurately placed on the plate cutting device.
